Description

The invention relates to a motorized drive device for

  the drive, between two extreme positions of a leaf closing an opening, such as a leaf of a vertically erasing door, to a door comprising such a drive device, to a method of operating the device. Motorized drive devices are already known for driving an opening leaf, in particular a door such as a

tilting or sectional garage.

  Numerous documents describe devices comprising a motorization at the end of a balancing shaft, for example documents EPA-592,374, FR-2

  696 207, FR-2 697 573, EP-A-526 781, FR-2 653 485.

  These devices require a space close to the frame to place the drive motor of the shaft which can lead to environmental problems. Numerous variants of doors are also known using a motorization device remote from the opening, fixed to the garage ceiling or the like, and connected to the opening by a shaft typically transverse to

  the door balancer shaft.

  Such structures are described for example in documents EP-A767

  288, WO-97/15745, EP-A-632 182, FR-A-2 711 175, EP-A-455 358.

  These devices however cause congestion of the door, in particular

  when the ceiling is far or too close to the opening.

  There are also known motorized drive devices fixed on the opening, mobile when the opening is moved. These on-board motorization devices on the upper part of the opening, cause vertical bulk and require adjustments in the implementation of

the door.

  These devices are for example described in documents FR-2,665,478,

US-3311 159.

  On the other hand, a person skilled in the art knows motorization devices comprising a motor shaft connected for example by a transmission belt or chains or gears, to the shaft of the balancing device. These devices require a mechanical adaptation added to the door, requiring the engine to be placed on the site after the door, to adjust the engine on the site after its break, cause congestion which can io require a significant lintel height, and cause a reduction of the

height of the passage height.

  The object of the invention is to overcome these drawbacks, by proposing a motorized drive device pre-assembled and preset in the factory, having a

  dimensions similar to that of a non-motorized door.

  To this end, the subject of the invention is a motorized drive and balancing device intended for driving between two extreme positions of a leaf closing an opening, such as a leaf of a vertically erasing door comprising a frame, the drive and balancing device extending longitudinally and successively comprising, from a first edge to a second edge, first means for connecting said device to the opening, a first half transmission shaft fixed to the first connecting means, a first drive output shaft driving the sash connected and coaxial with the first half transmission shaft, the motor casing, a second drive output shaft driving the sash, a second half transmission shaft connected and coaxial to the second drive output motor shaft, second means of connection to the leaf, return means being in

  additionally mounted on at least one of the two half transmission shafts.

  The first and second drive output drive shafts cooperate axially, with the distal end portions, distant from the first and second edges respectively of the first and second half transmission shafts. and

  are connected by blocking means to the distal end portions.

  The locking means are removable elements for fixing the distal end portions of the first and second half transmission shafts, to the first and second motor drive output shafts, and to

  spacers placed at the first and second distal end portions.

  The first and second means for connecting to the opening element comprise a cable winding drum mounted wedged on the proximal end parts of the drive shaft, close to the edges, and a lifting cable linked on the one hand to the part lower of the opening on the side of the drum, and on the other hand wound on the drum To The return means are in the form of a helical torsion spring mounted wound on the half drive shaft and the end part

  of the spring close to the drum being immobilized in rotation.

  A second object of the invention is a door comprising a leaf, sectional or not, guide rails, rollers cooperating with the rails, comprising

  a motorized drive and balancing device as described above.

  According to a variant, the door can be sectional with ceiling erasure and

  vertical travel, such as typically a garage door, manufactured, pre-

  mounted for installation, capable of being thus stored, delivered and supplied to the installation site, comprising on the one hand a first assembly including vertical lateral guide rails; a leaf comprising several articulated panels, rollers cooperating with the side rails; a motorization device as described above disposed longitudinally between the lateral rails, the cable winding drums being mounted wedged on the end parts of the drive shaft towards the outside of the leaf and between the latter and the side rails, the two cables being linked on the one hand to the leaf to the lower end panel, on the other hand wound on the drums, the cables not being thus undesirably assembled; electrical supply means located next to the door on a stable support and connected to a current source; and on the other hand, a second assembly including horizontal upper guide rails connected by a rear high crossmember. According to a first variant, the motor assembly is fixed to the upper cross member of the frame between the vertical rails. In a second variant, the motor assembly is fixed to the upper rear cross member for spacing the horizontal rails, the cables hoists being extended and returned to the bottom of the door by pulleys or the like. The motor casing is fixed to the upper cross member or the rear upper cross member of the frame spacing by fixing means such as angle brackets.

  fixing fixed on the one hand to the cross member and on the other hand to the casing.

  A third object of the invention is a device for monitoring and controlling a motorization device presented above comprising control means for switching over from a motorized mode using the device

  motorized in manual mode using manual operating means.

  The device comprises supply means, means for correcting the motor supply voltage, means for adjusting the parameters

  security and means of lighting the door.

  According to one embodiment, the adjustment means are in the form of a feeler bar fixed to the bottom of the door, the crushing of which causes the direction of rotation of the motor to be reversed and therefore the door to rise in the event of closing or a stop in the event of opening, an electric lock fixed inside the opening, and a detector of an obstacle or an overload of the opening. The device comprises means for controlling the opening and closing of the opening located at a distance from the transmitter type or near the push button type. A third object of the invention is a method of operating the drive and balancing device as presented above integrated into a door described above, comprising for the opening of the door the opening control steps , lighting of the interior maneuvering area, unlocking of the bolt, rotation of the motor in the upward direction, with control, detection if necessary of an obstacle or of an overload on the opening causing the stopping of the opening lifting cables on

  the drums, opening the sash, stopping the opening and ending the opening.

  io The maneuvering process includes for closing the door the steps of: closing command, lighting of the interior maneuvering area, rotation of the motor in the direction of descent, unwinding of the lifting cables on the drums, descent of the '' opening, stopping the descent, locking the bolt, checking, detecting if necessary an obstacle or

  overload on the opening causing the descent to stop.

  The invention will be better understood from the following description with reference to

  attached drawings, in which: - Figure 1 is a schematic perspective view of the interior side of a construction comprising a door according to the invention, shown closed, according to a first embodiment; - Figure 2 is a view similar to that of Figure 1, according to another embodiment; - Figure 3 is a sectional top view of the drive and balancing device of Figure 1 along the line I-I of Figure 1; - Figure 4 is a partial sectional view in enlargement of Figure 1, in the coupling zone between a motor half-shaft and a transmission half-shaft of the drive and balancing device according to the invention; - Figure 5 is an enlarged cross-sectional view of the device

  drive and motorization along line 11-11 of Figure 1.

  In the figures is shown a construction having an opening 1 to

which is intended for a door 2.

  The opening 1 is typically that allowing the passage of a vehicle

  automobile, door 2 therefore being a garage door.

  The ground is designated by 3, by 4 the lintel fallout and by 5 the spandrels, on one side and on the other. According to the constructive arrangements envisaged, the dropout of the lintel 4 and the spindles 5 are of reduced size, compared with those of the state of the art. For example, in one embodiment, the sizes are less than 10 cm and in particular of the order of 8 cm for the fall of the lintel and of the order of 9 cm

for each corner piece.

  Door 2 includes a leaf 6, movable between a closed position

  (Figures 1 and 2) and an open position.

  In the closed position, the leaf 6 is arranged vertically or substantially

vertically in opening 1.

  In the open position, the leaf 6 is arranged horizontally or substantially horizontally towards the ceiling adjoining the dropout of the lintel 4. The door 2 considered is therefore of the erasing type on the ceiling and vertical movement. It is also of sectional type, the leaf 6 comprising a succession of panels 7 similar or identical to each other. Two adjacent panels are arranged and mounted one on the other so as to be associated

  to each other by pivoting means 8.

  A leaf can also be a single piece, the door not being sectional, such as

than a tilting door.

  The door 2 also comprises lateral guide rails 9 and upper guide rails 10. These rails are arranged respectively vertically or

  substantially vertically, horizontally or substantially horizontally.

  They are placed inside the building, respectively on both sides

  and above opening 1. They are located near this opening 1.

  The rails 9 and 10 form two sets on one side and the other of the opening 1. Each of these two sets comprises one or two side rails 9 and one or two upper rails 10, the latter adjacent to the upper end portions. lateral rails 9. The two sets of rails 9 and 10 are located in two vertical planes parallel to each other, perpendicular to the plane of the opening 1. The rails 9 are fixed, directly or not, to the wall of the construction in which the opening 1 is made. The rails 10 are fixed

especially on the ceiling.

  We define by D a horizontal direction located in the plane of the opening 1,

  perpendicular to the plane of the two sets of rails 9 and 10.

  When the door is sectional, rollers are provided for each panel.

  Rollers 11 of axis D cooperating with the rails 9 and 10 are carried by the panels 7 projecting from their vertical lateral edges. The rollers 11 can slide in the rails 9 and 10 to allow movement of the leaf 6 between

  its open and closed positions.

  The cables are arranged vertically or substantially vertically between the lateral edges of the leaf 6 and the rails 9. They are located in the immediate vicinity of the plane of the opening 1. They pass between this plane and the roller supports 11. They

  are therefore not unwanted accessible.

  The panels 7 include a lower end panel 7a, an upper end panel 7b and one or more intermediate panels 7c. In the embodiment of Figure 1, the leaf 6 has a total of four

identical panels 7.

  The panels 7 have in front elevation a generally rectangular outline, the long side being horizontal and of direction D and the short side vertical (when the

door 2 is installed and closed).

  A panel 7 comprises a first and a second facing respectively 14 and 15, defining its large visible external faces, which are parallel. The facings 14 and 15 are made from thin metal sheets, rigidly secured to one another. In particular, the facings 14 and 15 are made from steel sheets with a thickness of the order of 0.4 mm. The two facings 14 and 15 are, in this embodiment, made from a

same type of thin sheet.

  According to the embodiments, the two facings 14 and 15 are made from different types of sheets. The sheets of the facings 14 and 15 can be made of materials other than steel, provided that this material is

  suitable for the use and performance required.

  The first facing 14 is that located on the exterior side of the construction, that is to say towards the "noble" visible face of the door 2. The second facing 15 clearly visible in FIG. 1, is located on the interior side of the construction (face 19).

  At least one of the facings - in this case the first facing 14-

  has at least one longitudinal stiffening rib,

  extending between the two vertical lateral edges of the panel 7.

  The internal space 58 of the panel 7, closed at the periphery by the two facings 14 and 15, is filled - at least partially - with a material

  synthetic which expands during manufacturing.

  Furthermore, the panel 7 is devoid of reinforcement or internal insert of

substantial stiffening.

  The total mass of a panel 7 according to the structure described can be of the order of

  9 to 10 kg / m2, especially around 9.5 kg / m2.

  However, despite this lightness, the rigidity of the panel 7 in bending is

excellent.

  This result can be achieved even when the facings 14 and 15 can be devoid of rib, groove or projection of substantial stiffening.

  extending in transverse direction.

  However, it would be possible to provide such -or-such rib (s), groove (s)

  or transverse stiffening projection (s).

  According to one embodiment, the depth of a longitudinal rib is of the order

  one third of the total thickness of the panel 7.

  The two sheets forming the facings 14 and 15 are rigidly secured

to each other.

  The panels 7 thus formed have the advantage of being of reduced weight. It is therefore the same for the entire leaf 6. This structure results in the cable winding drum

  may be of reduced diameter, such as between 65 and 75 mm.

  As a result, lintel fallout and spandrels can also

  be reduced in size, as indicated above.

  The drive and balancing device 13 of the door 2 will now be described. The drive and balancing device 13 comprises a first edge 18, and a second edge 19. From the first edge 18 to the second edge 19, the device 13 comprises, aligned and coaxial: - a first drum 21 for winding a first cable 29; - a first transmission half-shaft 22; - a first motor output shaft 23; - the motor casing 24; - a second motor output shaft 25; - a second half-drive shaft 26;

  a second drum 28 for winding a second cable 30.

  The device 13 extends substantially longitudinally, parallel to the direction D. The first drum 21 is fixed to the first end part 34 of the first transmission half-shaft 22. The first drum 21 is grooved helically externally, receiving a first cable 29 wound on the first drum 21, which first cable 29 is also fixed to the leaf 6 at

  lower end panel 7a.

  The first transmission half-shaft 22 is itself connected to the first shaft

  drive motor 23 of the motor by first blocking means 49.

  Symmetrically with respect to the motor in this embodiment, the device 13 comprises a second motor half-shaft, connected by second locking means to the second transmission half-shaft 26 supporting the second

  winding drum 28 of the second cable 30.

  The device 13 further comprises return means 31 fixed on the side of the drums. In the embodiment shown, the return means 31 are a first helical return spring 32 mounted on the first half transmission shaft 22. The first spring 32 comprises a first end part 38, towards the first end part 34 of the drive device 13 on the first side

  edge 18, and a second end portion 39 located towards the engine.

  The first end portion 38 of the first spring 32 is immobilized in

  rotation, being fixed relative to the frame of the construction.

  The second end portion 39 of the first spring 32, in this case that placed towards the middle portion of the drive device 13, is immobilized on the first half transmission shaft 22, and is therefore locked in rotation

relative to.

  I For this purpose, an insert 47 is provided, in the form of a ring, mounted on the first half-shaft 22 and wedged on it, possibly

  adjustable in axial position and in relative angular position.

  In the embodiment shown, the door 2 comprises a mounting 44 fixed to the

  sleeping above the opening 1, and in particular on either side of the latter.

  The assembly 44 firstly comprises a support piece 45 intended to be fixed to the frame of the construction, and supporting the first half transmission shaft 22. The assembly 44 then comprises a connecting piece 46 integral and molded

  in this embodiment by forming both a bearing 46a and a flange 46b.

  The assembly 44 also includes fixing members, such as screws for

  rigid fixing of the flange 46b on the support piece 45.

  The support piece 45 forms a cradle for receiving the connecting piece 46.

  The first drum 28 has on its transverse face, on the side of its connection with the first half transmission shaft, a hollow in which is mounted an added ring 43 interposed between the first half shaft

transmission 22 and assembly 44.

  We will now describe the assembly and the locking means 49 between the shaft of

  transmission 22, 26 and the motor shaft 23, 25.

  The motor comprises a casing 24. The two drive output motor shafts 23, 25 are coaxial with one another, and with the two half shafts of

transmission 22, 26.

  Each of the two drive motor shafts 23, 25 cooperates in rotation

  with the half transmission shaft 22, 26 located on the same side of the casing 24.

  More specifically, in this embodiment, the first drive motor shaft 23 cooperates with the second end portion 35 of the first half transmission shaft 22. In this embodiment, the diameter of the half transmission shafts 22, 26 is greater than the diameter of the trees engine

23, 25.

  Locking means 49 block the motor shafts 23 in rotation,

  drive on the half transmission shafts 22, 26.

  In one embodiment, the locking means are fixing screws 49 associated with intermediate spacers 53 slid to the distal end portions 35, 36 of the half transmission shafts 22, 26. The drive motor shafts 23, 25 protrude at the outside of housing 24

of the motor.

  The motor has a tubular shape in order to limit its size in the door. This size is thus close to the size generated by a

  balancing assembly not associated with a motorization device.

  The casing 24 is fixed to the upper crosspiece 4a of the door frame and to the lintel 4 using fixing brackets. In this embodiment, the device

  drive comprises two mounting brackets 50, 51.

  The casing 24 is immobilized at its end portions by screws

  fixing 52 of the casing 24 on the brackets 50, 51.

  In this embodiment, the two brackets 50, 51 fixed on the upper crosspiece 4a of the frame also allow the fixing of the device assembly

  drive 13 and balancing and frame on a rigid masonry support.

  The screws 54 allow the fixing of the brackets 50, 51 on the cross-member and

possibly on masonry.

  The brackets 50, 51 participate in guiding the balancing assembly.

  The motor used is typically of the reversible electric gearmotor type.

  The engine can be placed in manual operation mode. The user can then drive the door 2 using the manual operating means 48 placed in

  typically low position on the opening.

  To dismantle the motor, in particular in the event of replacement, the user dismantles the two brackets 50, 51 which support the drive and balancing device 13. He uncouples the first 23 and second 25 drive output motor shafts, first and second half transmission shafts 22, 25 respectively. The user then adjusts the cables 29, 30, this

  which does not require detaching them from the balancing device 13.

  We now describe the electrical installation of door 2.

  The motor is supplied from supply means 70 connected to a control box 56 fixed next to the door on a stable support. This box 56 is

  itself powered from a power outlet 57.

  This control box 56 further comprises monitoring and control means comprising: - means for correcting the supply voltage of the motor; - means for adjusting the security parameters, connected for example; - to a safety edge 60 fixed at the bottom of door 2, the crushing of which causes a reversal of the direction of rotation of the motor, and therefore a rise in the door in the event of closing or a stopping of the door in the event of opening; - force control means related to the presence of an obstacle or an overload on the opening, causing the opening to stop during the ascent or descent; - Locking means such as an automatic lock 61 placed in this embodiment on the top of the opening but can also be laterally on the opening;

  - lighting control means.

  We now describe the operating principle of the opening and the

door closing.

  For opening, the user actuates, by the control box 56, opening control means 71, typically either a transmitter or a push-button. The interior operating area of the door then lights up, with the

  if necessary a time delay device.

  The lock 61 is then unlocked.

  The motor is then driven in rotation in the direction of the leaf 6 rise.

  with winding of lifting cables 29, 30 on the winding drums.

  The leaf 6 is then driven from the bottom up, being guided by the lateral and upper guide rails 9, 10, at a variable or constant speed

  depending on the control device provided.

  The leaf stroke stops when the extreme opening position is reached, for example detected by an electrical contact at the end of the stroke or at

  using a revolution counter integrated in the control box.

  For closing, the user actuates the closing control means, of the transmitter or push-button type 71. The interior door operating area

  lights up, for example with a timer.

  The motor is rotated in the downward direction of the leaf with unwinding of the lifting cables 29, 30. The leaf is driven from top to bottom to an extreme closing position, for example detected by an electrical contact at the end of the stroke or using a revolution counter integrated in the control box. When moving the door, from the extreme closed position to the extreme open position, the leaf exerts an opening mass on the transmission shaft, and the spring exerts on the transmission shaft a spring torque, the torques decreasing in absolute value when the leaf is rotated. In the case of a door as described above, but not comprising a motorized drive device according to the invention, that is to say a manual door not comprising a motor, the adjustment is made so that the spring exerts a torque slightly greater than the torque exerted by the

leaf mass.

  When opening, this results in residual torque and the door rises alone.

  In the case of a motorized door comprising a motorized drive and balancing device as described above, the spring is adjusted so that the spring torque is slightly less than the mass torque

leaf.

  When opening, the door thus tends to descend if it is not driven by the motor. The engine torque is therefore adjusted to compensate

  this under-balancing during opening and allow opening.

  The engine is also able to respond to "accidental" situations. Thus, when the door encounters an obstacle in the descent, it stops, the mass torque then becomes zero. Conversely, when the door is exposed to a

  overload on opening, the mass torque increases.

  In both cases, the spring torque then reaches a triggering threshold value.

automatic engine shutdown.

  We will now describe the assembly of the different constituent parts of the

  motorized door and their pre-assembly.

  This pre-assembly allows two sets to be made.

  This pre-assembly is first described in the embodiment of Figure 1. A first set includes the lateral guide rails 9, the leaf 6 placed between them, the rollers 11 cooperating with the rails 9 and, finally, the drive device 13. A second set includes the upper guide rails

  , and the rear upper cross member 12 intended to connect them.

  The first set 6, 7, 9, 11, 13 is compact and fits in an envelope of generally flattened parallelepiped shape. Indeed, this first assembly is laterally limited by the rails 9, the drums 21, 28 not projecting from this assembly since placed between the leaf 6 and the rails 9. As for the cables 28, 29, they are incorporated in the hardware of door 2, i.e.

that they are not protruding.

  The first set of the door which has just been described is such that it can

  also be pre-set during manufacturing.

  This constructive arrangement is advantageous because it leads to quality pre-assembly during manufacture and avoids tedious operations,

  long or delicate at the final door installation site.

  Thus, the two assemblies which have just been described form a package which can be included in an overall thickness of less than 125 mm, while

  in the state of the art the thickness is close to and even exceeds 155 mm.

  Doors as they have just been described are conditioned.

  This packaging is easily transportable given the limited weight of the panels 7. The packaging allows for convenient standby storage of

  doors before they are installed in a building.

  For this installation, take a packaging door, bring it to the construction site, put in place and fix the said construction to

  first set 6, 7, 9, 11, 13 and the second set 10, 12.

  And we install the command and control means.

  The door having been pre-assembled in manufacturing and pre-adjusted, assembly can be quick. In the embodiment of Figure 2, the first set includes the guide rails 9, the leaf 6, the rollers 11. The second set is placed in the thickness of the door, and includes the rear cross member 12, the device 13, the upper guide rails 10. The cables 28, 29 are not pre-assembled, but fixed to the lower parts of

  opening it, while walking on the pulleys 63.

  The balancing spring is tensioned and then blocked on the half-shaft 22.
