Abstract

The mechanism has a drive member (1) e.g. in the form of an angled arm with one end (1A) moving in a slideway (11) in the door or window leaf (4). Its other end (1B) is equipped with an axle (2) carrying a cam (3) with an aperture (5) forming a cam track for a peg (6) connected to a drive (7). During operation the peg travels along the cam track to produce a controlled angular movement which is transmitted by the axle to the drive member (1) to open or close the door or window leaf or fix it in an intermediate position.

Description

The present invention relates to an opening-closing device a door leaf, shutter or the like.

It relates more particularly to a device opening-closing of a leaf of the type comprising at minus an operating member, such as a bent arm, of which the free end moves inside a slide equipping said leaf to move said leaf by a stroke generally close to 180 ° between a position opening and closing position.

Such shutter operating devices are in particular described in patent FR-A-2,717,216 and in US-A-1,676,064. Such devices have the advantage of being able to open and close doors, example of traditional shutters, without having to open the window to access it.

The major drawback of the wing operating device described in patent FR-A-2,717,216 resides in the behind the scenes complexity. Indeed, the path of these behind the wings is a complex path necessary to allow an offset to be obtained during the opening or closing of two actuated leaves simultaneously. The backstage must therefore be made either by milling a block made of a material allowing easy sliding of the operating member in said slide, either by plastic injection. Through elsewhere, such parts must each time be precisely installed on the leaves during the installation of such an operating device. It results from long assembly times.

The operating device described in the American patent above does not allow to meet the standards which require the design of a device anti-pinch in which in particular the crushing of fingers when closing the shutter is impossible. Through against, it solves the backstage problem mentioned about of the aforementioned French patent by offering backstage having a straight guide path.

Another door closing device is described in EP-A-0.559.947. This device includes a set of pinions and rack ensuring movement linear, possibly alternating, of a rod acting at its end on a profile of an integral cam in rotation of the door pivot axis to generate a angular displacement of the door at most equal to 90 °. The disadvantage of such a device, in addition to its bulk linked to its design which forces the rod and the cam to be arranged aligned, lies in the lack of control of the movement of the cam. So, for example, during a door closing, any action exerted on the door can generate an opening of the latter without one elements of the device could prevent such movement. It is easy to understand that such a system is not transposable in particular to shutters exposed to the wind and likely to be closed in an intermediate position.

The risk of accident would then become significant. Through elsewhere, this device essentially concerns doors whose closing stroke is controlled. As such, it therefore only belongs to the technological background of the present invention.

The aim of the present invention is therefore to propose a opening-closing device of a single leaf easy to install and whose design allows meet all safety rules and standards imposed for this type of device by preventing by especially any free, uncontrolled movement of the leaf other than that authorized by construction.

Another object of the present invention is to provide a leaf opening-closing device as a fully pre-assembled set, easily for example in the lintel of a closed opening by the clapper.

Another object of the invention is to propose a device opening-closing of a wing easily coupled to a other similar opening-closing device for allow, during a simultaneous operation of said devices, an early opening or closing of one of the fighters.

To this end, the invention relates to a device opening-closing of a door leaf, flap or similar, to move the leaf of a race generally close to 180 ° between the open position and the closed position, this device comprising at minus an operating member, such as a bent arm, of which the free end moves inside a slide equipping said leaf, characterized in that the maneuver is equipped at its other end with a pivot axis parallel to the pivot axis of the leaf, this pivot axis carrying a cam provided with at least one light forming a cam path inside which a finger moves taken with a leading organ, this finger, driven in displacement by said driving member, cooperating with the cam path to generate angular movement cam controlled transmitted through the pivot axis and / or from the cam to the operating member for cause the leaf to open or close, or bidirectional immobilization of the latter in a any intermediate position between the position opening and closing position.

Thanks to this design of the opening-closing device, precise and controlled angular movement of the operating member can be obtained by means of a device easy to manufacture and install. Otherwise, due to the presence of lights in the cam, the angular movement of the cam and consequently of the maneuver is continuously monitored, thereby ensuring safe immobilization of the leaf, at least within one predetermined force by construction exerted on this said beating, so that any unauthorized movement of the clapper is prevented. So the risk that the beating immobilized, for example in an intermediate position, opens or closes under the action of the wind is prevented.

According to a first preferred embodiment of the invention, the cam is integral in rotation with the axepivot, the rotational connection between the pivot axis and cam being a disengageable link when a force of value greater than a predetermined value is exercised on one side of the leaf.

According to a second embodiment of the invention, the cam is integral in rotation with the operating member, this rotational securing link being a disengageable link when a force of value greater than a predetermined value is exerted on one of the faces of the beating.

Thanks to this design of the connection between the pivot axis and cam or actuator and cam, any risk of injury due to jamming during shutter closure is prevented. So, such a device responds perfectly security standards.

The invention will be clearly understood on reading the following description of an exemplary embodiment, with reference to the accompanying drawings in which:

Figure 1 shows a perspective view of a window with a right wing in the open position, the window being equipped with an opening-closing device of said leaf according to the invention;

FIG. 3 represents a partial schematic view of part of the opening-closing device of a leaf fitted with a cremone bolt and

Figure 4 shows a partial sectional view of another embodiment of an opening-closing device according to the invention.

The leaf opening-closing device, object of the invention can equally be installed in the vicinity an opening 15 comprising one or two leaves. These leaves are indifferently door leaves, shutter or similar. This device can be applied to a leaf to the right of the opening (figure 1) or to a leaf disposed to the left of the opening (Figure 2). This leaf 4 is in known manner, pivotally mounted on a hinge 16, as shown in Figure 1.

This leaf opening-closing device is generally arranged, as shown in Figure 1, in the upper part of the opening 15 provided with the leaf (s) 4. The ideal is to be able to position this device inside the lintel of the opening 15. However, everything other positioning can also be considered.

In known manner, this device comprises a slide 11 integral with the wing 4 of the shutter, door or similar. This slide 11 can be produced in the form of an insert or be made up of a groove formed directly in the leaf panel 4. An organ maneuver 1 affecting, in the example shown in Figures 1 and 2, the shape of a bent arm, connects the opening-closing device of leaf 4 to slide 11. This operating member 1 is generally equipped at its end 1A, moving inside the slide 11, a roller 12 to facilitate this movement. His other end 1B is integral with the rest of the device opening-closing of the leaf. This bent arm can be made of several elements, for example the number of three. These three elements then include an elbow and two arm sections slidably inserted into the elbow portion to allow obtaining a bent arm easily adjustable in length so that adapt to renovation sites where the hinges are variably distant from the angle of the table, where the thickness of the flaps is variable and where we see the presence of bars or scarves on the flap which prevent sometimes the position of the slide at the place initially planned.

It should be noted that this opening-closing device of flying, although shown here in the case of the command an opening-closing of a leaf 4 pivotally mounted around a vertical axis, can also apply to a leaf pivotally mounted about a horizontal axis.

In addition to the operating member 1, this opening-closing device leaf has a pivot axis 2 fitted the other end 1B of the operating member 1. This pivot axis 2 extends parallel to the pivot axis of the beating. This pivot axis 2 carries a cam 3 mounted freely at rotation around said axis 2 (Figure 4) or integral in rotation of axis 2 (figure 2). This cam 3 is provided at least one light forming a cam path 5 to the interior of which a finger 6 moves in engagement with a driving member 7. This finger 6, driven in displacement by the driving member 7 cooperates with the cam path 5 to generate a controlled angular movement of the cam 3 transmitted via the pivot axis 2 (figure 2) and / or from the cam (FIG. 4) to the operating member 1 for cause the leaf to open or close, or possibly immobilization of the latter in a any intermediate position.

Preferably, the pivot axis 2, the finger 6 and the driving member 7 are housed at least partially inside a casing 9 while the operating member 1 is arranged below said housing. Cam 3 is indifferently positioned inside the casing 9 (figure 3) or below of the casing 9 (FIG. 4). This casing 9, of form general parallelepiped, is shown here open on two of its side faces. It is housed inside or in the vicinity of the lintel of the opening 15 closed by the leaf 4 controlled by the opening-closing device. This casing 9 is itself housed inside a tunnel 17 on which is fixed a motor. This tunnel 17 allows the holding two devices in an aligned position opening-closing equipping the same opening.

The opening-closing device, as described above, is a device that can be used interchangeably for opening the left wing or the wing right of an opening 15. Thus the device shown in Figure 1 is designed for the opening-closing of the leaf 4 right of an opening 15 while the device shown in Figure 2 is designed for opening-closing of the left wing of an opening.

In the example shown in Figures 1 to 3, the cam 3 comprising the cam path 5 substantially affects the form of a plate arranged between the upper faces and bottom of the casing 9, this plate extending substantially parallel to these faces. The pivot axis 2 carrying the cam 3 extends meanwhile orthogonally to said upper and lower faces of the housing 9. In the example shown in Figure 4, the cam 3 substantially affects the form of a plate placed outside the casing 9, substantially parallel to the underside of the housing 9 and below it.

Finger 6 can consist of a simple rod extending substantially parallel to the pivot axis 2 as shown in Figure 2. The driving organ 7 resulting in displacement finger 6 is an organ generating a rectilinear displacement of finger 6. This finger 6 which extends parallel to the pivot axis 2 is kept parallel to said pivot axis 2 during its movement.

Although a large number of leading organs 7, such as rack, cylinder, can be used for driving movement of finger 6, preferably the driving member 7 is an endless screw housed inside of the housing 9. This worm is rotated by means of a motor (not shown), generally arranged outside the housing 9. This motor is controlled by operation by a control unit generally located inside the building or in the vicinity of the opening. This worm screw passes through a threaded bore of finger 6 which is kept fixed in rotation on said screw 7 to cause, during the rotation of the screw, a linear displacement of the finger.

In the examples shown, the worm extends horizontally inside the casing 9 and the means of immobilization in rotation of finger 6 on the screw are constituted by lights 8 for guiding the ends free of the finger 6 formed in the upper faces and bottom of housing 9.

The worm is rotated in two directions of rotation to allow, in a first direction, a displacement of finger 6 in cam path 5 causing the opening of the leaf and, in a second direction, the leaf closing. 6 finger / cam path cooperation 5 provides perfectly controlled angular displacement or control of the cam 3. In fact, thanks to this embodiment, any movement of the leaf other than that imposed by the cam or wanted by the manufacturer is prevented. Indeed, in the case where the connection between cam 3, pivot axis 2 and operating member 1 is not disengageable, any movement leaf other than that imposed by the cam is prevented. Similarly, in the case where this link is disengageable, as this will be described below, a movement of the wing other that the one imposed by the cam is only possible in conditions imposed by the manufacturer. Consequently, the controlled movement of the cam free of any movement free to rotate around the pivot axis without declutching wanted by the builder brings a perfect mastery of the movement of the leaf.

As stated above and for reasons of security, it is sometimes necessary that the device door opening-closing is designed not to generate user injury, particularly by jamming when closing or opening the beating. To do this, in a first embodiment according to Figures 1 to 3, the pivot axis 2 is integral in rotation of the cam 3, the connection rotation between pivot axis 2 and cam 3 being a connection disengageable when a force of value greater than one predetermined value is exerted on one side of the clapper 4. So if fingers get caught between the clapper and part of the opening 15 during the closing of said leaf, the connection between pivot axis 2 and cam 3 is disengaged so that cam 3 continues to move under the combined effect of finger 6 and the path of cam 5 while the pivot axis 2 is kept fixed.

To allow this disengagement of the securing link in rotation between the cam 3 and the pivot axis 2, this connection consists of an elastic member 10, in this case a spring, integral with the cam 3, this elastic member 10 cooperating with a flat formed on the pivot axis 2 for generate a friction force on the pivot axis 2 sufficient to rotate the pivot axis 2 when an angular displacement of the cam 3.

Conversely, when the force exerted on one of the faces of the wing is a force of value greater than the force of friction between pivot axis 2 and elastic member 10, the rotational drive of the pivot axis 2 by the cam 3 is no longer insured. Obviously, sensors are provided respectively on the cam 3 and on the pivot axis 2 to detect such a situation and order the shutdown of the engine.

To return to normal operation of the device open-close, the motor is then actuated in direction reverse to bring cam 3 back to a position corresponding to the position it occupied in relation to the pivot axis 2 when the link has been disengaged.

In another embodiment according to FIG. 4 and for the same reasons as those mentioned above, we may consider that the cam 3 is integral in rotation with the operating member 1, this connecting link in rotation being a disengageable link when a force of value greater than a predetermined value is exercised on one side of the leaf. In this case, cam 3 and the actuator are both mounted free at rotation about the pivot axis 2 or at least one of the two elements is mounted free to rotate about axis 2. This pivot axis 2 is maintained in bearings of the housing housed for example in the upper faces and bottom of housing 9.

In the example shown in Figure 4, this link disengageable consists of an elastic member 20 of return of the cam 3 in position coupled to the operation 1, this return member 20 cooperating with balls 19 positioned between cam 3 and actuator 1 so as to generate by friction of the cam 3 on the actuator 1 a sufficient support force for drive in rotation the operating member 1 during a angular displacement of the cam 3.

In the case where an opening is provided with two leaves, an opening-closing device similar to that described above is installed on the other leaf. So, as example, it is possible to install the device opening shown in Figure 1 for the leaf right of an opening and the opening device shown in Figure 2 for the left wing of a opening. The motor for rotating the organ leading 7 of each device can then be arranged between the two housings 9 each containing a device opening-closing of the leaf and driving simultaneously the driving members 7 of each device. In the case where these driving members 7 are constituted by endless screws, these worms are not inverted. Path 5 of each cam 3 is adapted, that is to say differentiated to allow angular offset on opening or closing of said leaves.

Finally, the interest of such an opening-closing device is that it can be easily used for the leaf locking in open or closed position. So for example, to allow the locking of the beating in the closed position, the finger 6 is arranged to cause, during its movement beyond the closed leaf position, tension or loosening a cable 13 connected at one end directly or by through a connecting piece at a point any of the device and at its other end to the axis 14 of a cremone bolt equipping said leaf 4. The tension of the cable 13 generates a rotation of the axis 14 of the cremone bolt which locks the leaf in the closed position, this axis of cremone bolt being recalled when the cable is released in opening position of the cremone bolt by a spring reminder.

Such an installation is shown in Figure 3. In this installation, the cable 13 is fixed to one of its ends to a lever 18 pivotally mounted in a location of the casing 9 generally chosen on the face of the below the underside of the housing. On the way to this cable 13 can be arranged a nut (not shown) allowing adjustment of the tension of the cable 13. This cable 13 or the pivoting lever 18 pass through the light guide 8 formed in the underside of said housing so that they are on the travel path of finger 6. This intersection between cable 13 or lever pivoting 18 and finger 6 takes place when finger 6 occupies in the cam path 5 the position shown at Figure 2. Thus, we see that, in this case, the cam is arranged in such a way that the cam track 5 then extends substantially parallel to the axis of moving finger 6 so that the continuation of the movement of finger 6 in cam path 5 does not cause no movement of the cam 3. This cam is therefore in closed leaf position as shown by the position of the operating member 1.

Continued movement of finger 6 will therefore not have no action on the positioning of the leaf. On the other hand, during the continuation of its movement, the finger 6 tends to drag the cable 13 through it of the pivoting lever 18 and to cause its tension, as the shows the dotted representation in figure 3. This cable 13 is connected at its other end to axis 14 of the cremone bolt around which it is partially wrapped, as shown in Figure 3.

When finger 6 comes into contact with cable 13 or with the pivoting lever 18 and ensures the tension of the cable 13, the cable tends to pivot the axis 14 of the cremone bolt and this axis 14 of the cremone bolt is equipped so in itself known by hooks which then lock on stop members generally mounted in the opening closed by said leaf. The hook of the cremone bolt in the locked position of the leaf is shown dashed in Figure 3.

Unlocking is obtained by reverse movement of the finger 6. This reverse movement causes the loosening of the cable 13, a return spring helping the axis 14 of the cremone bolt to return to the initial unlocked position. Thus, thanks to the design of the opening-closing device of the leaf, it becomes easy to allow the locking in the closed position of this leaf.

The leaf can be locked in the open position obtained in a similar manner. This locking in position open is done for security reasons. he thus allows, in the case of a strong wind, avoid any accident, in particular by disengaging the connection between cam 3 and pivot axis 2. To allow this leaf lock in open position, finger 6 is arranged to cause, during its movement beyond the open position of the leaf, the tension or the loosening of a cable attached to one end directly or through a connecting piece at a point any of the device and at its other end to a leaf locking member in the open position. The cable tension generates passage from an inactive position to an active position of said locking member in open leaf position. This locking member is recalled, when the cable is released in the inactive position, by a return spring. The functioning of such locking device in the open position of the leaf is therefore analogous to that described in more detail above for a leaf in the closed position.

For security reasons and in particular in the event of power failure, an unlocking can be provided manual of these devices. So this device manual unlocking (not shown) can be set up by a stud arranged on the cable path, this stud being mobile only by rotational drive of a crank introduced through the leaf of said flap and allowing manual release of the cable. Once this unlocking performed, handling of the flaps is made possible after pressing hard on the leaf to disengage the connection between cam and pivot axis.

Thus, such an automatic opening-closing device does not in any way prevent the manual operation of such doors.
