FR2711174A1 - Electrical device for remotely opening and closing so-called "French style" shutters - Google Patents

Abstract

Electrical device for remotely opening and closing either solid or louvred (slatted) so-called "French style" shutters. The invention relates to a low-voltage electrical mechanism which can be used to open and close outside shutters, to lock/unlock an espagnolette bolt having a round rod and to immobilise the shutter in the desired position. A motor (39) with reduction gear and drive disengageable by a knurled knob (28), these being housed in a reversible housing mounted on a hinged mechanism plate (43), transmits a rotational movement to an adjustable angled arm (51), the other end of which includes a screw (56) which travels in a guide (58) with an angled piece (elbow) (59) fastened to the shutter (71) which it accompanies. At the end of the movement, the fitted end of the arm (66) causes the espagnolette bolt (68) to rotate, while pushing a flat iron with adjustable bearing element (60) acting as the latch bolt. A helical spring (not shown) brings the espagnolette bolt back into the initial position when opening is caused. According to the invention, the device is particularly intended for opening and closing so-called "French style" shutters by means of electrical control.

Description

tI 2711174 This invention relates to a device intended to open and

  close, remotely, the shutters called "à la Française" made of wood or any other material, straight

or bent.

  The shutters thus named, have the particularity of opening towards the outside, then of folding back on one side or on either side of the opening from which they then move away appreciably from the fact that they articulate around a hinge which acts as a pivot. they come to rest against the exterior plane of the construction using permanently sealed stops. This forces users to lean outward to manipulate them. To this must be added the maneuvering of the spanish, which, although not involving any major risk, cannot be carried out without opening the glass frame, which is unpleasant in bad weather. These basic operations for ordinary people can be difficult, even dangerous for physically impaired people or children, especially if you have to use a step. In addition, one can be confronted with the awkward or inaccessible situation of an exit, either located on the floor, or practiced above a piece of furniture as it is sometimes the case in the kitchens. The disadvantages are

  renew, thus, several times a day.

  There are devices on the market capable of operating such shutters from the inside. Those who are manual can only stand near the window sill. Those that are electric, attach themselves to the brace and

  are exposed to the weather while being unsightly.

  The device, object of the present invention, provides a remedy for these drawbacks and goes beyond if the flap to be fitted is lockable with a

  Round stem spanish. If this is not the case, only one operation is canceled, in this case the one which has the role of locking and unlocking the spanish.

  Whatever the case, the external retainers become useless since this device replaces them. On the other hand, operations are carried out without the need to open the window.

  This device is characterized by the fact that it consists of a relatively discreet, permanently fixed casing and of a guided arm responsible for moving the brace. Said box which is fixed on the panel, that is to say between the shutter and the glazed frame, shelters an electric mechanism with low tension, comprising a transmission at the end of which comes to adjust an arm of which the other end is based on a guide permanently fixed to the flap Thus, when a switch is pressed, the flap is forced to pivot in the desired direction. The arm, meanwhile, is equipped with a few accessories that extend its use to the

  maneuvering the spanish handle, both for locking and for the reverse operation.

  s Being a device operating on low voltage, therefore not involving electrical risks, the choice, as for the location of the switch, does not entail

no difficulty.

  The case, previously mentioned, contains a motor-reduction unit-

  transmission that it is responsible for protecting. Lubricated during assembly, it does not require any maintenance thereafter. It is universal (right or left). Its drive axis can be located above or below although having been designed to lead to below. The choice of its position is made at the time of assembly, before its mounting plate is adapted to it. Only the guide, which was initially planned for a flap with a rebate opening to the right, will undergo a

  tiny modification which will be, above all, of an aesthetic nature, when it is intended for a shutter without rabbet opening to the left.

  Seven and a half seconds are enough to cover the 180. The motor requires little energy (3 amperes at 12 volts DC) supplied either by rechargeable batteries, or by batteries (dry or rechargeable) or by a suitable transformer20 connected to the network. Each device has its own switch. In the event of damage, a manual declutching system enables it to be isolated. Although sufficiently powerful, the encounter with an obstacle, during pivoting, causes it to stop. Likewise, as soon as the pressure is released on the switch, the stroke of the brace is interrupted. This is why the flaps25 can be positioned ajar, except, of course, in strong winds, which could damage the mechanism. However, the same wind would not prevent

not pivot the shutter.

  As has been touched on previously, the housing itself is articulated. It is fixed, like a hinge, on a base provided with an axis and a spring responsible for absorbing any blows in both directions. Two screws with their dowels are enough to fix it. The junction of the box on its base is almost instantaneous. Two other wood screws (or agglo) keep the guide immobilized on the brace. A sheet metal screw or a metal screw (depending on the type of spanner encountered) is used for mounting an accessory on the rod. a rubber stopper fixed on the outside, on the last blade of the shutter or on the rebate, when it has one, is responsible for protecting the wood (or the

  P.V.C.) against the roughness of the wall.

  With reference to these drawings, the device essentially consists of two complementary, inseparable elements: - an electrically driven motor attached to a concentric reducer which causes the rotation of a final axis; - an arm responsible for transmitting the movement to a pivoting element (flap). The primary mechanism, more fragile, facing the weather, is protected, as well from humidity as from dust, by a molded case, of small dimensions, from which two parts emerge: the power cable and the secondary shaft on which comes to fix the arm. In a way, a box composed of two halves substantially equal in size and shape, but different in structure. According to the invention, this box is intended to be installed against the window panel (or of the French window) at a height previously chosen according to the location of the accessories. The most appropriate place, unless a particular situation comes to thwart the project, is, undoubtedly, under the lintel, out of the axis down. Indeed, an installation near the support would cause discomfort in the use of this space, especially when it is intended to receive flower vases or

  planters. The element that militates most in favor of a higher location is that related to bad weather. At this point, the device will be protected from direct atmospheric scourges such as rain or snow.

  For more convenience, an articulated plate, provided with a pivot and a damping spring, is interposed between this mechanism and the fixing point on the construction and absorbs any jolts. The molding is designed in such a way that the casing can be fixed with upward or downward transmission. On the other hand, it can be used on a right flap as on a left flap by simply changing the side of the fixing plate. It is only necessary to ensure that a space of 5 mm separates the internal vertical plane of the shutter (a

  once closed) and the outer and anterior edge of the case.

  The second element, accessory to the mechanism described above, consists essentially of profiled parts, unalterable and treated against

  severe weather. They are designed to be assembled together and make up additional equipment for the engine.

  These parts are fixed or mobile. The main element is constituted by a bent arm, made in a metal of square section which, by means of additional pieces, can lengthen or shorten to adapt to the type of window on which it must be fixed. He is responsible for printing the movement on the shutter following the impulse received on the control. It is also responsible for rotating the respagnolette a quarter of a turn to cause it to lock, then keeping it in this position. In order for these operations to be carried out, one end of the arm is integral with the transmission of the motor, while the other moves in a guide fixed to the interior wall of the brace. The length of this element, its shape and its section, have been dimensioned and calculated to offer & use in a fairly wide range of frames. It is of square, tubular section and has an underlying longitudinal groove and a bend at one end. A helical spring, intended to return to the initial position of the round iron plate and a flat steel bent finger, intended to be integral

  s of said espagnolette, complete the range.

  This device, which is designed to be used without having to use a professional for its installation, has the characteristics resulting from the invention and which are as follows: 1 - THE MOTIE1URRlEDUCTEUR-TRANSMISSION COMPONENT a) The engine: The active function of the mechanism is provided by an electric motor (39) with an outside diameter of 28 mm and an overall length of 40 mm. Its axis has a section of 2 mm. It exceeds the outside plumb on one side, 8 mm and has a flat over a length of 6 ramm. A pinion (49) 6 mm in diameter and 5 mm in length, comprising 8 teeth, engages on said axis through a central hole with a suitable flat. The diameter at the base of the teeth is 4.5 mm. This pinion is made of brass. He went up to the press. Its teeth are cut longitudinally in a quasi-triangular shape. The motor plate, pinion side, is fitted with a nylon ring (38) hollowed out to be held together by two 1.5 mm sheet metal screws (88). The outer diameter of this one is 35.5 mm. Its total thickness is 5.5 mm, 2 mm of which form a shoulder 30 nun in diameter intended to be housed in the body of the reducer (34). Two lugs 1.5 mm high and 1.5 mm wide, diametrically opposite, protrude from the outer periphery to combine with

  2s the anti-torque ribs (48) of the body of the reducer, on the end of which they come to bear.

  This motor works with a direct current of 12 Volts. Its direction of rotation is reversed by change of polarity caused by a switch. It requires an intensity of 1.4 amps and a power of 15 watts to produce its maximum force. The speed thus obtained is 11,500 revolutions per minute. Its power can come from a dry battery, a rechargeable battery, a

  accumulator or transformer with adequate rectifier. Their duration is, of course, a function of the type of energy source, and above all the daily stresses on the device.

  b) The reducer: Coupled directly to the motor, this accessory is metallic and its mechanical machining very precise. The body (34) is cylindrical and smooth. Two diametrically opposite longitudinal shoulders (48) 1.5 mm high s and 1.5 mm wide extend over its entire outer height. The outer diameter of this hollow cylinder is 35.5 mm. The internal diameter is 30 mmn. The interior wall is lined with longitudinal grooves of triangular section, the height of which is 1.25 mm. These grooves are 58 in number and constitute regular teeth whose base joined together form a diameter of 10 32.5 mm. They extend to the base of the cylinder, the thickness of which is 7.5 nmm. The external height is 41.5 mm, the internal height, in other words, the length of the teeth, is 34 mm. An orifice of 8 mm in diameter crosses the base in the middle and ends, outside of the latter, in a bowl (92) of 13 mm in diameter and 5.5 mm in height, which serves as a housing for a clip to

  is circular spring (79) resting on a flat steel washer (91) calibrated to limit the lateral play of the primary transmission shaft (32) during the effort.

  The cup (92) houses the spring (23) responsible for pushing the primary pinion (22). Inside the cylinder (34) there are several mechanical parts, the combined rotation of which leads to a considerable reduction in the initial speed of the engine. Firstly, we have seen that the motor transmits its energy through the 8-tooth pinion (49). Trapped in the reducer, this pinion moves in the axis of the cylinder between three toothed wheels (36) machined in mild steel 13.5 mm in diameter and 4 mm in height, around which 24 teeth are arranged. with a triangular profile, 1.25 mm high, thinned on the tips of the side faces25 in order to reduce their friction. These three wheels, which we will call "planetary" (36) rotate around an individual axis (47) fixed at equal distance from each other, forming an equilateral triangle of 15.5 mmn side. These three axes (47) are integral with a crown (35) against one of the faces of which they are integral with one of their ends. This crown (35) measures 25 mmn in diameter, at a height of 3 mm_ It is made of mild steel On the face opposite the three planetary gears (50) made of steel 6 mm in diameter, 4 mm in length and comprising 8 triangular teeth similar to the motor pinion (49) is integral with the part and takes place in the center of said face.The crown (35), the central pinion (50), the three axes (47) and the three planetary (36) form an association which we will call "element". The reduction gear cylinder (34) houses four of these elements, three of which are strictly identical. Only the fourth differs from it. Indeed, the pinion (50) integral with each crown,

  has given way, on the fourth crown, to the primary shaft (32) the place it occupies.

  2711174 The element (37) thus formed takes place inside the cylinder (34) in which it is the first engaged, the shaft (32) occupying the orifice of the base (33) of said cylinder which is, remember, 8mm. A mild steel washer (78) has been previously interposed between the crown (37) and the bottom of the cylinder (33) to reduce friction. This washer measures 12 mm in diameter and I mm in thickness. the shaft (32) is immobilized by a spring clip

  (79) placed in its groove formed on the shaft at the outlet in the bowl (92) and wedged by a calibrated washer (91).

  The three other reduction elements, will take place, one after the other, in the body of the cylinder (34), the pinion (50) of each of them, coming to take place between the planets (36) of the element preceding it. The last element

  engaged, receives, meanwhile, the drive pinion (49), after two steel washers (87) 30 mm in diameter 1.5 mm thick and having an orifice of 8 mm, came to take place between the three visible planets and the nylon nylon ring (38). During assembly, the gear unit is lubricated with bearing grease.

  Thus constituted, the reducer occupies a limited space. while retaining its initial torque and without absorbing a lot of energy, the motor of which we have said, the speed of rotation is situated at 11,500 revolutions per minute, will, at the outlet of the concentric reducer, rotate the primary shaft (32) at 4,185 revolutions. 20 To go into detail, we will say that crown 1, that is to say that driven by the motor, will perform, in the same period of time, 1,588.3977 rotations, crown 2, placed just after, will make 219.3919 rotations, the crown 3: 30.3027 rotations and finally, the driving crown: 4.1854 rotations per minute. This speed will be further reduced at the output of the secondary shaft (13) 2s to 3.8964 revolutions per minute. This feature will be described in the next chapter. c) Trusn sion This mechanism, as it was designed in this invention, will cause the rotation of the secondary shaft (13) on which is fixed the bent arm (51) connecting the housing to the shutter This tree forms an angle of 90 with the primary shaft (32), hence the need for a joint composed of two bevel gears with conical size

  right, right out of the reducer.

  In the previous description, concerning the reducer, we have

  found that the primary shaft (32) transmits the rotation of the last ring (37) with which it is integral. This shaft has a total length of 31 mm, two of which are lost in the crossing of the base (33) of the reducer. Having an initial diameter of 8mm, this will be reduced to 6mm on the 25mm measured from the spring clip s (79) to the end. However the difference is used to make four longitudinal ribs (93) of the square section (1 x lmm) diametrically opposite and also spaced, which are interrupted 2mm before the end to use it as a pivot with the transverse bearing ( 20) described later These ribs correspond to grooves of the same size and of the same arrangement, hollowed out inside the axial orifice of the primary toothed wheel (22) of 14 teeth into which the shaft slides after interposition of a helical spring (23) whose function is to force the pinion to remain in contact with the toothed wheel (17) and also allow its retreat during disengaging. This spring, itself is made with steel wire of 12/10 section. Its diameter is 12mm outside and its height before mounting is 12mm for 3 and a half turns. After assembly, its height is 8mm, the extreme turns having been previously adjusted to the square. One end is backed by the clip (79), the other rests against the rear part of the pinion (22) which constitutes the stop (95) of the clutch release fork (24). This stop has a diameter of

  1 8mm and a thickness of 2mm. The groove in which the fork (24) is housed offers a width of 6mm and its internal diameter is 12mm.

  The primary gear (22) is made of brass. The self height is 8mm and the maximum outside diameter is 23mm. The total height, including the stop, is 16mm. The size of the teeth is conical, straight and 45 to 45. There are 14 of these. They are in the form of an isosceles trapezium, the long side of which is the base which measures 3.096mm and the short side of the top which is 2.064mm wide before rectification. The angle formed by the two sides of the teeth is 71. The height of the teeth, which is 2mm at the base, forms a circle of 19mm. This height goes to I mm at the top and we get a circle of about 9mm (approximate diameter since it follows from the size to 45). Thanks to its longitudinal opening of 6mm in diameter, mentioned, which has four grooves of 1 X lmm, the pinion and, consequently, the stop, circulate on the primary shaft (32) during the back-up stresses on the occasion of a declutching operation. The shaft, as far as it is concerned, accommodates its end of 6mm in diameter and 2mm in width (94) in the orifice of the same dimension provided for this purpose in the bearing (20). The latter is cut from l 2mm rolled steel. 11 has the shape of a polygon with six sides or, in other words, of a rectangle from which two angles at the end of the same length would have been removed and, consequently, reduced the sides, to add two sides additional. Its largest 0o length measures 42mm, its shortest length, parallel to the first and

  2711174

  also distributed on each side of its median, measures 13mm. The two perpendicular widths have a height of 12mm while the two transverse sides which join one end of the widths with the ends of the short length measure, each, 17nmm. The 6mm hole intended to receive the end of the primary rarbre (94), is located on the median of the greatest length. The axis of this hole is 5mm from the base of it. The bearing (20) takes place in the lateral guides (21) of the interior housing by the short sides, enters the transverse groove (96) arranged in the upper reinforcement (19) of the secondary axis (13) against which it s supported by one side. It is maintained

  o10 in this position by the secondary gear (17) against which it is backed by the edge of the greatest length.

  When the primary pinion (22) has found its place between the bearing (20) and the spring (23), it has 40mrnm of longitudinal travel to retreat during the declutching function. This distance is more than enough to allow it to detach from the secondary toothed wheel (17) while undergoing the grip caused by the rotation of the primary shaft (32) thanks to the combination of

  ribs and grooves previously mentioned.

  The secondary shaft (13) is perpendicular to the primary shaft (32). This axis is turned in mild steel and its total length is 60mm. It is neckline and bored at 8mm over a length of 32mm, then at 21mm over a height of 1.5mm then at 12mm over a length of 9.5mm. Then, it has a square of 8mm side on a height of 5mm, then a threaded part at 8mm with a pitch of 125 over a length of 12mm. This axis emerges through the orifice provided in the lower casing (2) of 14mm in diameter, with a ring reducing it to 25 12mm. The bevel gear (17) has been previously fixed there using a tubular steel pin of 3 x 14mmn against the circular shoulder (16) on which it is supported by its posterior plane. Then, the 8mm smooth part is housed in the internal circular inner reinforcement (19) of the housing (1) by means of a bronze ring acting as a bearing (18). This ring is cylindrical and has a base 2mm thick. The inside diameter is 8mm and the outside diameter is 13mm. The outside height is 7mm, the inside height, of course, 5mm. The total height of this ring is reduced to 4 mm on one side, by the rectilinear and vertical removal, over a height of 3 mm, of the thickness in order to obtain a flat. This is intended to house the part

  upper bearing (20) against the vertical axis and in the groove (96) provided in the semicircular reinforcement (19) of the housing (1).

  In the lower part, the drive axis (13) (or secondary shaft) passes through the thickness of the casing (2) through a reinforced zone inside (9) and outside (8) bored at 14mm where is housed a bronze ring with an internal diameter of 12mm and comprising, at one end, a flange 1.5mm thick and 21mm in diameter which will then take place between the plate (16) of the axle and the internal reinforcement of the casing (9) in order to reduce friction. This ring is placed in the press. After having emerged outside the casing (2), said axis successively receives a flat washer of 21mm outside diameter and 2mm thick (6) with a square hole of 8mm side which abuts, for one side, against the 12mm cylindrical part, the other side of which is then in contact to serve as support, in turn, at the end of the arm provided for this purpose. AT

  on this occasion, it compresses the O-ring (14) housed in the external reinforcement of the casing (8). Finally, a flat washer of 21mm outside diameter, 2mm thick, bored to 8mm, will fit between the arm and the cap nut (4). The arm and its complements are the subject of a description in a next chapter.

2 - MANUAL RELEASE

  We have seen, in the foregoing, that the electric motor transmits its movement to the primary shaft through a reduction gear, which shaft (32) drives a toothed wheel (22) of conical size, which in turn transmits the movement to another toothed wheel of the same type (17) integral with the secondary shaft (13) mounted perpendicularly We also noted that from an initial speed of 11,500 revolutions, we managed to rotate the arm of the around 4 turns. If the motor encounters little difficulty in driving the arm actuating the shutter, under normal conditions of use of the device, it would, on the contrary, be difficult or even impossible to drive the engine by pushing the shutter, without running the risk seriously damage the engine mechanism due to the difference in torque. However, any mechanical device is not without functional hazards, whose origin can be accidental or consecutive to a lack of energy. Whatever the cause, it would be insecure, in what concerns us, to be forced to leave the shutters open or, on the contrary, inconvenient to remain the shutters closed when, suddenly, the device is subject to a parmnne. For this reason, the apparatus which is the subject of the present invention has been provided with a small mechanism which is fairly rudimentary, but effective enough to dissociate the primary shaft (32) from the secondary shaft (13). This device which we will call "declutching" although it differs somewhat from the system commonly used in automobile mechanics, is

  composed of some internal parts to the housing associated with external parts.

  In the previous description, concerning the components of the primary transmission, we found that the 14-tooth bevel gear

  (22) was engaged on a rarebre (32) between the transverse bearing (20) and the helical spring (23) which forced it to remain in contact with the toothed wheel of 16 s teeth (17). We also noticed that the primary pinion (22) had a machined posterior part, integral and that a groove of 3 x 6mm in section and whose internal diameter was 12mm was formed by the posterior plane of said pinion and a stop of l8mrm in diameter and 2mm thick. This assembly is mobile and can move longitudinally on the shaft (32) but cannot pivot on itself due to the presence of the ribs (93). In normal operating position, a coil spring (23)

  pushes it against the transverse bearing (20) and consequently, against the secondary gear (17).

  In order to isolate the two cogwheels, a fork (24) has been provided as follows: Cut from the laminated racer, it consists of two identical elements somewhat in the form of inverted "tees", the junction point of the two branches that compose them is slightly offset. Their section is based on 6 x 3mm. The transverse branches have a length of 16mm. They have an orifice at each end, on the longest side, 3mm in diameter. The axis of these is located 3mm from the circumference rounded in a semicircle. The middle branch has a length of 17mm. Its longitudinal axis, meanwhile, ends at 7mm from the end located on the side of the link (27), therefore 9mm from the opposite end where its pivot will be located The junction is at 90, however the 2s middle branch has a setback of 1.5mm over a length of 1mm, starting from the edge of the transverse branch, where the angle is rounded, up to 5mm from the end which is semi-circular. The face, thus reduced, adjoins the posterior plane of the primary pinion (22) during assembly; This arrangement is intended to avoid discomfort and friction between the fork and the pinion when the latter recoils during disengagement. When each of the two elements of the fork is made, each of the two middle branches undergoes a double bending on their lesser thickness which consists in flaring the middle branches at their rounded end until a gap of 12mm is obtained for an interval of 3mm at the level of their respective transverse branch. During this operation, the median branches which had, as we have said, a length of 11.7mm, each lose two millimeters. The respective planes of the flared vertices are parallel to each other, vertically and longitudinally, as is the base.

  formed by the two transverse branches.

13 2711174

  The two elements are then assembled using the axis (25) of 20 x 3mm, which occupies the orifices located on the longest side of the transverse branches, to immobilize thereon, halfway length, a space of 3nmm always separating said branches. The fork (24) is now made. s The axis slides in the horizontal grooves of the support (100) of the housing (1) while each element of the fork is housed, at the base, between the three guides of this

  support, the description of which is given on page in the chapter relating to the upper casing (1). The widened median branches, as far as they are concerned, are placed in the groove formed by the back of the pinion (22) and the stop (95). The hole made in

  the other end of each of the transverse branches, is intended, for its part, to receive the 3 x 12 flat head pin (26) having a groove 2mm from its end intended to receive a spring clip This axis performs the junction with the steel link (27) leading to the outside of the casing (1). The special features of this piece are as follows: its head, flat on top, has a diameter of 8mm and a thickness of at least 2mm. The underside of the head has two asperities of triangular section, diametrically opposite. Their height is 2mm which brings the head to 4nmm in the same place. The rod of the rod, which has a cross section of Smm and a length of 18mm, measured from the tip of the asperities mentioned, has two flats diametrically opposite the other end. These have a length of 7mm and reduce the thickness of the link to 3mm. Thus thinned, this end is perforated transversely to 3mm. The axis of this orifice is located 3mm from the end, and in the longitudinal axis. She

  then fits between the two transverse branches of the fork (24) until the orifices coincide. The axis (26) assembles them and a spring clip immobilizes the latter.

  On the external side, the head of the link (27) is housed from above, against the external circular part of a wheel (28) of cadmium-plated steel 13mm in diameter, provided with an arm 20mm in length. The height of this part is mm, the part concealed by the link head (27) corresponds exactly to the latter both by its shape and by its dimensions. In other words, it could be the mold. The central part of this kind of bowl is provided, in its center, with an orifice of 5mm in diameter over the entire height of the wheel which rests, on the other side, on the reinforcement (29) of the casing ( 1) by means of a flat brass washer (31) 13mm in diameter, 1mm thick and 3s with a central opening of 5mm. An O-ring 5mm in diameter and section Imm (30) is placed in a housing in the reinforcement (29) on the outside of the housing (1). During assembly, the action of the helical spring (23) of the primary shaft (32), pushing the fork (24) forces the wheel (28) to press the washer (31) and the seal (30) by way of consequence; In the normal operating position, the wheel arm is located in the direction of the longitudinal axis of the upper housing (1), on one side or the other of its axis. The male protrusions of the rod head being housed, in turn, in the corresponding female cavities of the wheel, while at the other end, the axis (26)

combines rod and fork.

  To cause the primary pinion (22) to disjoin from the secondary toothed wheel (17), the thumbwheel (28) makes a quarter turn to the right or to the left.

  o0 This maneuver causes the recoil of the pinion (22) which slides on the primary shaft (32) and compresses, at the same time, the spring (23). Indeed, the link (27) can not, itself, pivot since held between the two elements of the fork (24) by the axis (26). For this reason, it retreats outwards, pushed in this by the difference in level of the male and female asperities s15 of the underside of the link head and of the external plane of the wheel, the respective action of which is opposed, the asperities are not in the same transverse axis. The recoil measured at the end of the fork (24), pressing against the stop (95), is 2.5 mm, that is to say the space available between the turns of the spring (23). the toothed wheels being disconnected, the secondary shaft (13) can pivot freely and, consequently, the arm (51) can come and go without encountering opposition and above all without the motor member undergoing any deterioration. To again cause the junction of the two toothed wheels (22) and (17), it suffices to rotate a quarter turn, in one direction or the other, the arm wheel (28). The rod head (27) will then be housed in the corresponding female cavity, will resume its place by withdrawing inwards, freeing from its grip the fork (24) which will retreat under the effect of

  helical spring (23) initially compressed during the disengagement operation. The two pinions will then be reunited again.

3 - THE BOX

  This piece, whose primary role is to protect the mechanical organ,

  is used to support certain elements of the mechanism itself.

  For this, it includes facilities intended to support, support or even

block active parts.

  For clarity of the explanation, we will consider that the rear part is that which is on the interior side of the building and which presents the outlet for the power cable. Conversely, the front part is "s 2711174

  the one outside, which houses the transmission.

  As described in Figures 10 and II (page 6/8) and according to our invention, the housing consists of two half-shells, one upper rune (1) the other lower (2) molded in "rigiplast" (name deposited), whose shape is approximately that of a rectangular parallelepiped with rounded corners and edges. Its external dimensions, vertical to the walls are as follows: length 148mmn, width 52rmm, height 46mm. The presence of a junction "belt" brings the housing to the following dimensions: length: 160mm, width 65mm, height to 51mmn. The wall thickness is generally 2mm, except in certain areas where reinforcements have been added. The two half-shells are assembled using a belt (10) which is located at mid-height and on the external and internal periphery of the housing. The two halves assembled, form a projection of 6mm in width and 6ram in height. This belt has 10 matching s15 holes for the passage of the rivets (11) of 3mm in diameter. Four of these are located at the corners, four on either side of a 13mm space arranged in each length, intended to accommodate helical fixing springs (44). At the center of these spaces, an orifice milled inside, serves as a housing for a screw (12) for fixing said springs. The other two holes with 20 rivets (1 1) are located between the anterior rivet and the rivet adjoining the screw hole

(12) on each longitudinal side.

  Inside the housing there is also a belt similar to that previously described with regard to the dimensional characteristics. The only difference lies in the fact that this inner belt has male and female half-round ribs around the periphery of 2mm in width and 1mm in height. The outer side of these profiles corresponds to the vertical of the inner wall of the housing. Taken individually, the upper casing (1) has a belt 14mm wide, 3mrnm high and a male rib (84). As for the lower casing (2), the belt which it presents has the same characteristics, except that the rib (85) is female. The junction of these two ribs seals the housing. By examining the closed case, we notice, on the posterior width, an orifice of rectangular section of 6mm of width and 4mm of height, whose axis is located at 14mm from the external plane of the longitudinal wall, allows the housing of the joint sealing rubber (42) of the power cable (41) with two 7.5mm2 conductors. On the side wall, molded at the same time as the latter, vertically, are located on either side of the front part of the housing, two intermediate nodes of hinges composed, themselves of two superimposed parts integral with the respective casings. These nodes have a vertical opening of 3mm, form an isosceles triangle of 15mm base, which merges with the wall of each housing and whose opposite row is straight and in a semicircle. When the housings (1) and (2) are assembled, the total height of these protrusions is 25ram. These knots are intended to form the central part of the hinge joint, two other parts (top and bottom) of which are located on the fixing plate at the

dormant (43).

  External examination of the case reveals other particularities. They are essentially prominences intended to reinforce the wall around areas subjected to torsional forces. Thus, the lower casing (2) has a crown 28mm in diameter and 3mm in height (8) relative to the outside plane of the wall. The central hole of 14mm in diameter, reveals on its outer periphery, withdrawal of 0.75mm in width and 1.03mm in height, intended to accommodate an O-ring (14) of 12mm inside and 1, 5mm of 15 section. The axis of this orifice is located 24mm from the external plane of the anterior wall and in the longitudinal median axis of said casing, which does not have, moreover, any other external characteristic. On the upper casing (1), the external features are also located in the anterior horizontal zone. Indeed, set back 45mm from the vertical plane of the external front wall20 of the casing (1) and in the median axis of its length, is the location of the declutching mechanism. I is a 5mm orifice whose vertical axis is located in the middle of a circular crown of 21nmm outside diameter and 2mm thick (29) in which has been fitted the housing of an O-ring on the outside. This measures 5mm inside diameter and 2.2mm

  section (30). It is intended to seal around the link (27).

  The two half-housings having been separated, the internal examination reveals, on each of them, the presence of several reinforced or arranged zones in order to maintain the mechanical organs in their place and, possibly to serve as support for other parts. These details are particularly visible on the

  Figures 10 and 11 attached on page 6/8.

  a) - The upper casing () First, we notice the perimeter belt 6mm wide and 3mm high which adjoins, on the other side of the wall, the outer belt thus forming a plane 14mm wide and 3mm high. View

7 2711174

  horizontally we notice the protrusion of the watertight rib

  (84) with half-round section of Imm height and 2mm width.

  Five profiles of rectangular section are arranged transversely and are used as supports for the motor and the reduction gear. Adherent to the internal peripheral wall, they offer a circular cradle of width and diameter which can be varied individually. are described from the rear plane of the housing to the anterior plane. The first profile has a thickness of 5mm. It has a dual role: it holds the gear motor unit longitudinally and laterally. The rear plane is located 1 mm from the internal wall of the casing and forms a semicircle 2 mm thick and 26 mm in diameter and a semicircle of 3mm thick and 28mm in diameter, molded together. 20mm from the internal posterior plane of the wall, the posterior plane of the second 2mm thick profile is located and forms a 28mm circle. It is intended to support the motor around its perimeter. The third profile has the same characteristics as the previous one, in terms of its shape, dimensions and use. Its posterior plane is located 49mm from the plane of the same wall. At 91.5mm from it, is the posterior plane of the fourth section, 2mm thick and 35.5mm in diameter, on which the exterior face of the base of the concentric reducer (33) rests longitudinally20 by the vertical walls. interior of the belt (10). The fifth section of a

  thickness of 2mm, is separated from the previous one by a vacuum of 2mm. Its diameter is 26mm. This is used as a longitudinal stop for the engine assembly -

  reducing and opposes the first profile. Between the third and fifth sections, two ribs of 3 x 3mm square section protrude from the horizontal and longitudinal plane of the casing, separated by a space of 1.5mm which will serve as a housing for the anti-torque rib (48) of the reducer, and which will pass beyond the fourth

  profiled at the same level of the cradle thereof. Between the two ribs, the thickness of the wall of the casing will be 3.75 mm and will be in abutment with the external part of said anti-torque rib.

  All these sections are integral with the casing over their entire outer perimeter.

  After the fifth section, in the area where the transmission is located, two lateral and vertical guides (21) pass through the interior junction belt (10) leaned over their entire length, to the vertical interior wall. These guides, intended for holding the laminated bearing (20) seen from above, have a square section. A space 2mm wide and 6mm deep is provided on the face

  opposite the housing wall. This space is interrupted 12mm from the inside plane of the bottom of the housing. It houses the lateral sides of the bearing (20). The middle of the groove which they comprise is situated 27 nm from the internal plane of the front wall of the casing.

  In the same zone of the casing, there is the orifice for the passage of the declutching link (104) whose axis is 3mm from the anterior vertical plane of the fifth section and on the median of the casing. Still on the longitudinal median, axis 22mm from the inner and anterior wall of said casing, seo10 locates the cylindrical housing (99) of the bronze ring (18) whose diameter is 13 mm and the depth is 7 mm. This ring, once engaged, is flush with the upper plane of a semicircular reinforcement of the casing (19) which is located 9mmn from the interior plane of the horizontal wall of the said casing, or it begins gradually to decrease then, until measure l9mm in diameter. The outline of this semicircle then extends longitudinally, on each side of the median to 9.5mm from the latter, in other words, to 8mm from the vertical plane of the inner belt (10). At 8mm from the circular housing axis of the bronze ring (99), the extension thus described, forms over its entire height (9mm) a three-pronged fork whose base is integral with the wall of the casing. The length20 of each tooth is 8mm, thus leaving a transverse space of 8mm measured on the anterior wall of the fifth profile. These three teeth measure respectively: 5.5mm, 3mm, and 5.5mm. The interval between the outer teeth and the central tooth is 3 mm. A groove 3mm wide is dug transversely and horizontally in the height of the three teeth. The bottom of 2s this one is in a semicircle. The maximum depth is 6mm, the axis of the pivot (25) which will occupy it will therefore be 4.5mm from the vertical plane of the said teeth forming the support (100). The central tooth is intended to separate the two elements from the fork (24) which are thus housed in the intervals formed with the outer teeth. The axis of the pivot (25) will also be 4.5mm from the axis of a 2mm wide groove (96) which crosses the support (100) transversely, overlapping the thickness of the bronze ring previously cut on one side as described on page 11 line 6 and along the edge of the orifice 8mm from said ring (18) which houses the end of the secondary shaft (13). This groove (96) is located exactly in the extension of those which are made in the lateral and vertical guides (21) described in the previous page line 38. There, the small length of the transverse bearing (20) is housed, the front face of which East

  attached to the secondary shaft (13).

  b) - The lower casing (2) The internal examination of the lower casing (2), that is to say the one through which the secondary shaft (13) emerges, presents little difference from its counterpart. It has the same number of half-arch profiles as those contained in the upper casing (1) because they are the extension of each other to form a circle. For this, they are supported by their horizontal edge located at the same level as the plane of their half-belt with the half-hangers of the corresponding profiles having the same characteristics: the axis of the circle thus formed, coincides with the central and longitudinal axis of the interior space of the housing when it is closed. It is in this space that the motor and the concentric reducer are housed, which thus remain immobilized laterally and longitudinally and, also, between them. The notable differences between the two casings, are located on the one hand, at the level of the sealing ribs (85). We noticed that the casing (1) included isimeter ribs with a curved profile having a width of 2mm and a height of lmm and the outer edge of this rib merges with the vertical plane of the wall

  internal. The lower casing (2) has, for its part, ribs with a hollow profit located in the same configuration, thus coinciding with the previous ones to overlap when the two casings are assembled.

  The second match is located at the lateral and vertical guides (21) of the transverse bearing (20). The latter, who have the same profile as

  those of the upper casing extend over 3mm, that is to say over the height of the inner half-belt (10). The groove which they comprise also extends over the entire height. On the one hand, it will merge with that of the casing (1) and on the other, it will receive the side edges of the bearing (20) when it is put in place.

  The notable feature that can be seen on the casing (2) is located around the outlet of the secondary transmission. Indeed, the adequate reinforcements help to consolidate the box itself, during the efforts of the mechanism. For this, the external reinforcement (8) already described, is extended inside the casing 30 by forming a circular protuberance of 28mm in diameter and 4mm in diameter.

  height, but whose diameter decreases regularly until measuring 21mrm.

  The hole which crosses this reinforcement from side to side has, as for the reinforcement (8), a diameter of 14 mm intended to accommodate the bronze ring with flange (15) which

reduces the hole to 12mm.

  4- THE BOX FIXING PLATE (43)

  This part is complementary to the housing. It is the normal extension of it because it is necessary for its attachment to the frame of the opening to be fitted. It is molded and designed in the same material as the housing on

  s which it adapts simply and quickly.

  Having somewhat the shapes of a rectangular parallelepiped, its dimensions are as follows: 120 x 46 x 6mm. Two 5mm orifices (90) flared on the opposite side to that intended to lean against the frame, are made in the median longitudinal axis, one at 17mm from the small anterior side, the other at 33mm from the small posterior side. Their interval is therefore 71 min. One of the planar faces is arranged to form a hinge with the corresponding nodes (89) integral with the housing. For this, two thicknesses are added to give offset to the articulation axis (45). These two parts, which are molded at the same time as the plate on which they adhere, have the form, seen from the longitudinal plane, of two isosceles triangles whose run of the sides has been truncated. The latter is located near the anterior part of the plate itself. As for the angle formed by the two sides which were originally equal, it has been rounded. Their respective height is 10 mm and the outside plane coincides with the plane of the thickness of the plate. The interval between the two planes facing each other is 26mm, which corresponds to the height of the node secured to the housing which will be housed between them. The base of the isosceles triangles which was originally to be 42mm is reduced to 34mm by removing the front side portion of the plate. The height of the offsets thus obtained is l2mrm, which corresponds to the height of the median of the triangles initially planned but rounded in an arc of a circle with a radius of 3mm. These two polyhedra each have, over their thickness, an orifice 3mm in diameter, the axis of which is common and concentric with the rounding already mentioned. The interval between the internal plane of the stage and the axis of

  the orifice is 9 nm. The sectioned part of the sides of the triangles forms a right angle with the plane of the plate and its base is located 1 mm from the anterior edge of the plate. In the middle of the short anterior side, on the same plane as the half

  hinges, a small rectangular parallelepiped of 11 x 6 x 3mn, is attached to the plate by its widest plane. The short side is plumb with the anterior edge of said plate and the remaining angle is rounded. This protrusion thus obtained forms a limit stop (82) intended to protect the shock-absorbing spring (44) in the event of excessive extension of the housing when the shutter Au closes.

  if necessary, it is supported on the external and vertical plane of the joining belt (10).

  2t In its rear part, the plate comprises the housing of a profile (80) of rectangular section with external 15 x 4mm and 25mm in length. The thickness of the cadmium metal in which it is made, is 1mm. One of the two widest surfaces was grooved lengthwise over a width of 7mm. This accessory fixed in the ad hoc housing previously fitted in the thickness of the plate, by means of a rivet, is intended for

  trap the last of the five turns of the helical spring (44). This is made with 15/10 steel wire, has an outside diameter of l3mm and its first turn will be reduced to form a 4mm diameter hole intended to engage the nut screw (12).

- THE GUIME ARM AND SFS ACCESSORIES

  Responsible for communicating the energy of the driving organ, the arm (51) fixed on the secondary shaft (13), drives the shutter in the desired direction. In order to perform

  this movement without anarchy, it is accompanied by a guide (54) whose shape has been designed with a view to using accessories for the purpose of operating the spanish plate when the shutter is closed and / or reopened.

  This arm is made with 10 x l0mm fercarré for what is essential, then 12 x l2mm square tube and lmm thick then 25 x 4mm flat iron, resettable cadmium-plated after manufacture, as exposed to the

severe weather.

  The square iron of 10 is divided into three sections, two straight sections and one angled section at 105. Their assembly is carried out using small sections of square tube previously arranged to be used as adjustment slides, all immobilized, then, using nut bolts and

4 x 20 mm flat washer. The guide (54) is made with section iron tube

  12mn square outside and 9am inside. It consists of two sections assembled at 90, grooved over their entire length on one side and completed by two brackets (65) for their attachment to the flap The whole is cadmied

to escape oxidation.

  In detail, the confection and the assembly are carried out as follows: a) - The hras (51) As mentioned above, the arm is produced using three sections of

  s 10 mmn solid square iron, intended to be assembled end to end by interlocking in intermediate square tubes of the same interior dimension.

  The first square iron section is straight and has a length of 52mrnm.

  At one of its ends, a flat iron 25mm wide, 45mm long and 4mm thick is inserted over 10mm and in the horizontal axis. This part (53) has been arranged to adapt to the secondary shaft (13) emerging from the housing. It comprises, in fact, in the longitudinal axis, a square section orifice of 8mm side and whose center is located 12, Smm on the short side. The diagonal of this square merges with the longitudinal axis of the arm after this piece has been immobilized by welding in the ad hoc recess of the square which is in fact, a groove 4mm wide and 10mm deep. Once the welding has been carried out, we can see that the axis of the square is located 22.5mm from the end of the section of the guide. For aesthetic reasons, the exterior angles are ground to obtain a semicircle and the angles located on either side of the junction are also cropped to give a flared shape to the flat iron. The female square which has just been mentioned takes place on the male square of

the secondary shaft (7).

  On the other end of the previously described section, is fitted, by interlocking, a square tube section of 10aOm of internal width and 64mm in length, which is inserted over a depth of 22mm to be thus welded. This accessory has a groove 5mm wide, acting as a slide in the longitudinal axis of the two side faces. It begins in a semicircle 8mm from the free end of the tube and ends in the same way

  24mm from the other welded end, a length of 36mmn.

  The second part of the arm is made in a length of iron 2: a

23 2711174

  172mm full square, bent slightly rounded to form an angle of 105, of which one side is 60m long and the other is 112nmm long. The short side (angle seen from above) is drilled transversely and in the median axis of the sides, at 4mm, the axis of this orifice being located 7mm from the end. This is intended to accommodate a nut bolt (55) of 4 x 20m which crosses, at the same time, the solid square and the slide to immobilize them together after adjustment

of the desired length.

  The long side (l 12mm) receives a square tube identical to that which we have just described, but whose length is 120mm. The longitudinal groove

  measure, meanwhile 64mm measured from the free end. The other end is welded to the square after it has been nested on 32mm.

  The third section of the arm is practically straight. One end engages in the square slide tube welded to the long side of the bent element after a 4mm orifice has been made 7mm from the end to allow the passage of a bolt (55) which will immobilize the two pieces after

length adjustment.

  The other end of this section, which has a total length of 200mm, is sectioned longitudinally and in the axis over a length of 25mm. One of the two halves, thus obtained, that located on the side opposite the angle of the second section, is removed at its base. The cut made for this operation will release an obtuse angle of 152. Half of the remaining iron, which we will call "finger" (66) is folded from its base towards the space thus freed up to form an angle of 155. During this operation, this finger (66) loses 2mm along its length. It is then bevelled on the outside on a length of 6nrm to finish in rounded 2s. Thus obtained, the part responsible for making the quarter-turn to lespagnolette (66) acquires a shape which will allow it to follow the plane of the shutter, during the closing thereof, without deviating too much from it. At 48mm from the end (before bending) the section will have been previously drilled vertically in the longitudinal axis and tapped at 5mm with a pitch of 90 right through This hole receives a hexagon socket head screw (56) . Its dimension is 5 x 15mm and its rod is threaded on 1 Imm. Once screwed and blocked from above, the base of the head will emerge 4mm above the upper plane of the square of the arm (51). This

  space allows to engage the screw head in the slide and to imprison it.

  The arm, after assembly, will have the minimum dimensions of: 168mm for the short side measured from the axis of the transmission (13) to the axis

  median of the angle; 340mm for the long side measured from the median axis of the short side to the end of the finger (66).

  It will have the following maximum and respective dimensions measured under the same conditions as above: 240mm for the short side and 404mm for the long side. This arm, thus designed, can be adjusted to most of the existing widths of rebate shutters. For shutters without round stem spandrel and

  comprising, therefore, another locking system, it is not necessary to remove the finger (66) because of the risks of oxidation at the level of the saw cut.

  b) - The profile guide (58) The guide (58) described below, equips a rebate shutter with Spanish

with round stem.

  As mentioned above, this piece is complementary to the arm.

  It is made in square tube of 12mm section and 1.5mm thick which offers an interior passage of 9mmin. Its length is 300mm whatever the width of the brace used. It forms a right angle bend (59) whose offset is 40mm taken on the short side of the assembly and, therefore, 52mm on the long side. Seen from above, the rectilinear part, towards you, the reference is located on the left, that is to say, at the end of the end close to the spanish. On the rectilinear part, two 12mm wide brackets (65) cut from 20 x 30mm drawn steel angle iron, are welded, one mm from the elbow, aure 30mm from the other end, measurements established on the median axis of the squares previously drilled at 5mm on the long side at 9mm from the end. This one faces down while the short side goes over

  of the guide, 'end flush with the outer vertical wall thereof.

  On the lower face, the guide has a longitudinal groove 6mm wide overlapping the longitudinal axis. This groove continues along the length of the bent part obstructed at its end to serve as a stop for the screw (56) and thus limit the stroke of the arm when it has been trapped inside the guide (58) by the other end. The edge of the internal junction angle of the two elements of the guide, will be reduced to form a rounding of 5 3mm radius. This will facilitate the initiation of the direction of the screw (56). For a flap without rebate and without Spanish, the angled part of the guide will be

  deleted and the guide will be brought closer to the outer edge of the brace by about 20mm to prevent the wash (56) from coming out of its groove, in the final phase.

  C) - The aeessoires complimentai d hr These are two in number. They are only useful if the brace is

  fitted with a round stem spanish.

  First, a kind of appendix (60) made in flat iron 12 x 4mm with a length of 55mmn. Seen by its song, it presents at one end, a curve forming an arc of a circle of 90 and 9mm in radius. Halfway through this rounding, a milled orifice on the outside of Smm in diameter occupies the center. i is intended to receive the screw (61) of 5 x 10mm which will fix it on the stem of the spanish. The other end of the part has been bevelled on the flat which corresponds to that having the "curved" of the curve and the angles obtained filed so that the part has no roughness. On the lower edge, 20 the rounding on the left, a small flat iron square of 10 x 10 x 4mm, carrying a central orifice tapped at 4mm with a pitch of 60, is welded by the edge, the axis of the hole 13mm from the beveled end of the appendix (60). In this hole, a 4 x 10mm round head machine screw (97) is engaged by the plate located on the side of the offset of the arc of a circle. This screw is intended to adjust the support of the part (60) 25 on which it adheres, with respect to the flap, on the one hand and with respect to the elbow

  upper part of the plate (68) which must be as close as possible to the sealed stop (69).

  The mentioned appendix (60) will be fixed on the round rod of the latter, the arc of a circle will follow its shape and the screw (61) will occupy the hole made in the center of the arc

  of circle. This part is treated against oxidation.

  Secondly, a cadmium-plated steel spring 20mm in diameter (62) made with 8/10 steel wire is used to return the plate to the rest position. This spring, introduced turn after turn, is supported by a curved end held by a screw on the brace and by the other end in a 2mm orifice previously made on the stem of the spanish. Before its final fixation, the spring will have been tensioned to

  have five turns instead of four that it has before installation.

  Under these conditions, the upper elbow (68) of the span, in the rest position, will form an almost right angle with the plane of the flap. When the electrical device is requested to operate the closing of the brace, the arm will engage, at the end of the race, under the appendage (60) via the end of the arm (66). Continuing its action, and entering the curve (59) of the guide (58) it forces the appendix (60) to perform a quarter turn necessary for locking. When unlocking, the reverse operation will take place and the spring 10 (62) will return the plate to its initial position. It should be noted, however, that between the two maneuvers, the finger (66) was held at the end of the elbow (59) of the guide (58) bearing on the appendage (60) effecting its blocking instead of the manual articulated handle which therefore becomes useless but which should be kept in the event of an incident 6- LEOUEIPEfMENT ELECIOQUE

  The device, as described, does not require in the state, the use of sophisticated equipment to equip a shutter. It includes very basic wiring

  : electric wire with two conductors of 0.75mm2 and a toggle switch with five connections, responsible for reversing the polarities of the current source for

  change the direction of rotation of the motor. The switch does not have the advantage of a detailed description because it appears on the outfits of the shops of

  trade in automobile accessories. We will only say, that it is mounted on a plate. This plate is itself fixed to the construction using suitable screws. The current source, on the other hand, is left to the choice of the user. If dry batteries are chosen, their location will depend on the location of the switch and discretion. If you opt for rechargeable batteries, you should think about recharging them, therefore think about the type of device responsible for this operation. In this case, it is preferable to equip yourself with a single 12V battery fitted with male plugs for connection. The charger will be fixed permanently. Its operation will be automatic. If the choice is on a transformer i rectifier this last must have at least, an energy of 15 watts and 3 amps so that the motor offers all its power. Its implantation will only be conditioned by the aesthetic result.
