Description

lO) Device for opening and closing a door leaf, shutter or

similar

  The present invention relates to an opening device

  closing a door leaf, flap or the like.

  It relates more particularly to an opening-closing device of a leaf of the type comprising at

  at least one operating member, such as a bent arm, the free end of which moves inside a slide fitted to said leaf.

  Such shutter operating devices are in

  particular described in patent FR-A-2,717,216 and in patent USA-1,676,064. Such devices have the advantage of being able to open and close shutters par3 (0 example of traditional type shutters without having to open the window to access them.

  The major drawback of the leaf operating device described in patent FR-A-2,717,216 lies in the complexity of the slides. Indeed, the path of these slides integral with the leaves is a complex path necessary to allow obtaining an offset when opening or closing two leaves actuated 2 simultaneously. The slides must therefore be produced either by milling a block made of a material allowing easy sliding of the operating member in said slide, or by plastic injection. Furthermore, such parts must each time be precisely installed on the leaves during

  the installation of such an operating device. This results in significant assembly times.

  ) The operating device described in the aforementioned American patent does not, for its part, meet the safety standards which impose the design of an anti-pinch device in which in particular the crushing of fingers when the shutter is closed. is impossible. On the other hand, it solves the backstage problem mentioned in connection with the aforementioned French patent by proposing backstage

  having a straight guide path.

  The object of the present invention is therefore to propose a 2) opening-closing device for a leaf which is simple to manufacture, easy to install and whose design makes it possible to

  meet all the safety rules and standards imposed for this type of device.

  Another object of the present invention is to provide a leaf opening-closing device in the form of a completely pre-assembled assembly, easily accommodated for example in the lintel of an opening closed by the leaf. another object of the invention is to propose a device

  opening-closing of a leaf easily coupled to another similar opening-closing device to allow during simultaneous operation of said devices an early opening or closing of one of the leaves.

  3 To this end, the subject of the invention is a device for opening and closing a door leaf, a shutter or the like, of the type comprising at least one operating member, such as a bent arm, the free end of which moves inside a slide fitted to said leaf, characterized in that the operating member is equipped at its other end with a pivot axis parallel to the pivot axis of the leaf, this pivot axis carrying a cam integral in rotation with said axis and provided with at least one lumen forming a cam path inside which moves a finger engaged with a driving member, this

  finger, driven in displacement by said driving member, cooperating with the cam track so as to generate an angular movement of the cam transmitted via the pivot axis to the operating member to cause the opening or the leaf closing.

  Thanks to this design of the opening device

  closing, a precise angular movement of the operating member can be obtained by means of a device which is easy to manufacture and to install.

  According to a preferred embodiment of the invention, the rotational securing connection between the pivot axis and the cam is a disengageable connection when a force of value greater than a predetermined value is exerted on one

of the leaves.

  Thanks to this design of the connection between the pivot axis and the cam, any risk of injury by jamming during the closing of the shutter is prevented. So, such a device

  perfectly meets safety standards.

  The invention will be clearly understood on reading the

  Following description of an exemplary embodiment, with reference to the accompanying drawings in which:

  FIG. 1 represents 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 wing in accordance with the invention, FIG. 2 represents a perspective view enlarged of an opening-closing device of a left wing similar to that shown in 1I) Figure 1 and Figure 3 shows a schematic view

  partial of part of the opening device-

  closing of a leaf fitted with a cremone bolt.

  The leaf opening-closing device, object of the invention, can be installed in the vicinity of an opening 15 comprising one or two leaves. These leaves 4 are indifferently door leaves, shutters or the like. This device can be applied to a leaf disposed 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 FIG. 1.25. This leaf opening-closing device is generally disposed as shown in FIG. 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

  ) the interior of the lintel of the opening 15. However, any other positioning can also be envisaged.

  In a manner known per se, this device comprises a slide 11 secured to the leaf 4 of the shutter, door or the like. This slide 11 can be made in the form of an insert or be constituted by a groove made directly in the panel of the leaf 4. An operating member 1 affecting, in the example shown in Figures 1 and 2, the shape of a bent arm, connects the opening-closing device of the leaf 4 to the slide 11. This operating member 1 is generally equipped at its end 1A, moving inside the slide 11, with a roller 12 for facilitate this movement. Its other end IB is secured to the rest of the leaf opening-closing device. This bent arm can be made of several elements, for example three in number. These three elements then include an elbow and two arm sections slidably introduced into the elbow portion to allow obtaining an elbow arm easily adjustable in length so as to be able to adapt to renovation sites where the hinges are variably distant from the angle of the table, where the thickness of the shutters is variable and / or there is the presence of bars or scarves on the shutter which prevent

  sometimes the position of the slide at the place initially planned.

  It should be noted that this leaf opening-closing device, although shown here in the case of the command

  of an opening-closing of a leaf 4 pivotally mounted about a vertical axis can also be applied to a leaf pivotally mounted around a horizontal axis.25 In addition to the operating member 1, this device d 'opening-

  leaf closure comprises a pivot axis 2 fitted to the other end IB of the operating member 1. This pivot axis 2 extends parallel to the pivot axis of the leaf. This pivot axis 2 carries a cam 3 integral in rotation with the axis 2. This cam is provided with at least one light forming a cam path 5 inside which moves a finger 6 engaged with a driving member 7. This finger 6 driven in movement by the driving member 735 cooperates with the cam track 5 to generate an angular movement of the cam 3 transmitted via

  the pivot axis 2 to the operating member 1 to cause the opening or closing of the leaf.

  Preferably, all of this opening device-

  closure as described above, namely the pivot axis 2, the cam 3, the finger 6 and the driving member 7 is housed at least partially inside a casing 9 with the exception of the operating member 1 which is arranged below said casing. This casing 9 of generally parallelepiped shape and shown here open on two of its lateral faces. It is housed inside or in the vicinity I) 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 a motor is fixed. This tunnel 17 allows the maintenance in

  aligned position of two opening-closing devices15 equipping the same opening.

  The opening-closing device, as described below

  above, is a device which can be used indifferently for the opening of the left wing or the right wing of an opening 15. Thus the device represented in FIG. 1 is designed for the opening-closing of the wing

  4 on the right of an opening 15 while the device represented in FIG. 2 is designed for the opening-

  closing the left wing of an opening.25 In the example shown in the figures, the cam 3 comprising the cam path 5 substantially affects the shape of a plate disposed between the upper and lower faces of the casing 9, this plate s extending substantially parallel to these faces. The pivot axis 2 carrying the cam 3 extends as

  to it substantially orthogonally to said upper and lower faces of the casing 9.

  The finger 6 can be constituted by a simple rod extending substantially parallel to the pivot axis 2 as shown in FIG. 2. The driving member 7 causing the finger 6 to move is a member generating a rectilinear movement of the finger 6 This finger 6 which extends 7 parallel to the pivot axis 2 is held parallel to said

  pivot axis 2 during its movement.

  Although a large number of driving members 7, such as rack, actuator, can be used for driving movement of the finger 6, preferably the driving member 7 is an endless screw housed inside the casing 9. This worm is driven in rotation by means of a motor (not shown), generally arranged outside the casing 9. This motor is controlled in operation by a control member generally located inside the construction or near the opening. This worm screw passes through a threaded bore

  of the finger 6 which is kept fixed in rotation on said screw 15 7 to cause during the rotation of the screw a linear movement of the finger.

  In the example shown, the worm extends horizontally inside the casing 9 and the means20 for immobilizing the finger 6 in rotation on the screw consist of slots 8 for guiding the ends

  free from the finger 6 formed in the upper and lower faces of the casing 9.

  The worm is rotated in two directions of rotation to allow in a first direction, a movement of the finger 6 in the cam path 5 causing the opening of the leaf and, in a second direction the closing of the leaf. As stated above and for safety reasons, it is essential that the leaf opening-closing device is designed not to generate injury to the user, in particular by jamming, when closing or the opening of the leaf. To do this, the rotational securing connection between pivot axis 2 and cam 3 is a disengageable connection when a force of value greater than a predetermined value is exerted on one of the sides of the leaf 4. Thus, if fingers are wedge between the leaf and the frame of the opening 15 during the closing of said leaf, the connection between pivot axis 2 and 5 cam 3 is disengaged so that the cam 3 continues to move under the combined effect of the finger 6 and from

  cam 5 while the pivot axis 2 is kept fixed.

  To allow this disengagement of the securing connection 1) 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 to generate, by friction on the pivot axis 2, a bearing force 15 sufficient to rotate the pivot axis 2 during an angular displacement of the cam 3.

  Conversely, when the force exerted on one of the sides of the leaf is a force of value greater than the friction force between pivot axis 2 and elastic member 10, the rotation drive of the pivot axis 2 by 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 control the stopping of the engine.

  To return to normal operation of the device

  opening-closing, the motor is then actuated in the opposite direction to bring the cam 3 back to a position 30 corresponding to the position it occupied relative to the pivot axis 2 when the connection has been disengaged.

  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. Thus, by way of example, it is possible to install the opening device shown in FIG. 1 for the right wing of an opening and the opening device 9 shown in FIG. 2 for the left wing. of an opening. The drive motor for rotating the driving member 7 of each device can then be arranged between the two casings 9 each containing a device 5 for opening and closing the leaf and simultaneously driving the driving members 7 of each device. In the case where

  these driving members 7 are constituted by endless screws, these endless screws are not inverted. The path 5 of each cam 3 is itself adapted, that is to say differentiated to allow the angular offset at the opening or at the closing of said leaves.

  Finally, the advantage of such a leaf opening-closing device is that it can be easily used for locking the leaf in the open or closed position. Thus, for example, to allow the leaf to be locked in the closed position, the finger 6 is arranged to cause, during its movement beyond the closed position of the leaf, the tension or the loosening2) of a cable 13 connected at one end directly or by means of a connecting piece at any point 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 cremone pin being recalled when the cable is released in

  opening position of the cremone bolt by a return spring.

  3 (0 Such an installation is shown in FIG. 3. In this installation, the cable 13 is fixed at one of its ends to a lever 18 pivotally mounted at a location of the casing 9 generally chosen on the face of the underside of the underside of the housing. On the path of 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 guide light 8 formed in the face lower of said casing so that they are on the path of movement of the finger 6. This intersection between cable 13 or pivoting lever 18 and finger 6 takes place when the finger 6 occupies in the cam path 5 the position represented in FIG. 2. Thus, it can be seen that in this case, the cam is arranged in such a way that the cam path 5 then extends substantially parallel to the axis of movement of the finger 6 so that the pursuit movement of the finger 6 in the cam path 5 does not cause10) no displacement of the cam 3. This cam is therefore in the closed position of the leaf as shown in the position of

the operating member 1.

  The further movement of the finger 6 will therefore have no action on the positioning of the leaf. On the other hand, during the continuation of its movement, the finger 6 tends to entrain with it the cable 13 by means of the pivoting lever 18 and to cause its tension as shown by the representation in dotted lines in FIG. 3. Ce2) cable 13 is connected at its other end to the axis 14 of the cremone bolt around which it is partially wound, as

shown in Figure 3.

  When the finger 6 comes into contact with the 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 come to 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 in dotted lines in Figure 3.

  Unlocking is obtained by reverse movement of finger 6. This reverse movement causes the release of the

  cable 13, a return spring helping the axis 14 of the cremone bolt to return to the initial unlocked position.

  It thus, thanks to the design of the opening device-

  closing the leaf, it becomes easy to allow the locking in the closed position of this leaf.

  Locking in the open position of the leaf can be obtained in a similar manner. This locking in the open position is carried out for safety reasons. It thus makes it possible, in the event of a strong force wind, to avoid any accident, in particular by disengagement of the1) connection between cam 3 and pivot axis 2. To allow this locking of the leaf in the open position, the finger 6 is arranged to cause during its movement beyond the open position of the leaf the tension or loosening of a cable fixed at one end directly or15 via a connecting piece at any point of the device and at its other end to a leaf locking member in the open position. The tension of the cable generates the passage from an inactive position to an active position of said locking member in 2) open position of the leaf. This locking member is recalled when the cable is released in the inactive position,

  by a return spring. The operation of such a locking device in the open position of the leaf is therefore similar to that described in more detail above for a leaf in the closed position.

  For safety reasons and in particular in the event of a power failure, it is possible to provide for manual unlocking of these devices. Thus, this manual unlocking device (not shown) can be constituted by a stud disposed on the cable path, this stud being movable only by driving in rotation a crank inserted through the leaf of said flap and allowing the manual release of the cable. Once unlocked, manipulation of the flaps is made possible after pressing the leaf firmly

  to disengage the connection between cam and pivot axis.

  Thus, such an automatic opening-closing device in no way prevents the manual operation of such leaves. i
