Description

The present invention relates to motorized actuators for mobile Locking plates, like a door or a goal.

For example, in the case of a Tors this latter at least one movable wing that on a fixed structure, a pillar or a wall around an axis realized by mandrels is articulated. The actuator is thus arranged between the fixed structure and the movable wing, this device being an actuator in the true sense of any suitable known type, hydraulic or electromechanical, and comprises at least two articulation axes, which are essentially parallel to the articulation axis of the wing the fixed structure, one of the articulations in the vicinity of the fixed structure and the other near the wing is arranged.

In the event of a device defect due to any malfunction, with the wing in the closed position is blocked, it is necessary to neutralize him to open, this process generally by disconnecting the device from the drive of the wing carried out becomes.

However, with the known Devices this decoupling not easy because in the closed position the actuator exerts a hanging force like this that the means that for the loosening or decoupling the drive device of the wing are difficult are to be handled. For example, it is a device in document FR-A-2 469 543 which describes a realization of a Linkage between the actual actuator and a block provides that in one on the wing attached slide rail and with this slide rail using a locking screw can be firmly connected, which acts through friction, such that the bigger the Frictional force is all the more difficult to unlock.

A first object of this invention is an actuator, especially for to propose a goal that does not have this disadvantage and that in Quite the opposite in the event of a defect or any malfunction can be easily disconnected.

To this end, the invention an actuator a movable closure plate, which is hinged to a fixed structure is to the subject, this actuator between the fixed structure and the movable plate is arranged and at least one actuating element and comprises at least two joints, means being provided, around two elements of the actuator uncoupling and so the movable plate in case of malfunction free, characterized in that the means have a locking mechanism of the type comprising a striker plate carried by one of the elements and comprises a latch carried by the other member, wherein the locking plate includes a control body that allows the bolt to be released, the force necessary to operate the control member very much is much less than that and essentially independent of the hanging force is that of the actuator is exerted between the bolt and the striker plate.

The locking mechanism is convenient of a kind like the belt buckles or equipping the vehicles Seat belts are used.

It's also important that Gate close can if the actuator is still broken and it is important to keep it in the closed position to be able to lock again. This process can be difficult when decoupling the device generates a release of the games at normal operation due to the effect of the hanging force, to hold the plate in the closed position against the stop shoe be eliminated again.

To solve this particular problem includes the device according to the invention means for compensating for unlocked games.

These funds can be in different places the device. For example, you can use one the joints must be integrated, the axis of which is at least two each can take appropriate positions, one in normal operation and the other in the event of a fault in the device.

According to a special embodiment, the articulation of the arm on the sliding shoe is realized by means of an articulation piece which has at least two positions can to modify the position of the axis of the linkage.

These agents can also be used in the locking mechanism, closing plate and bolts, are installed and include an additional blocking member, that works with the bolt in such a way that the latter is blocked in a position that is different from that in which it normally locks in the striker plate, this additional Blocking element resettable is attached to release the bolt.

Another disadvantage of known ones Devices lies in the fact that the decoupling of the actuator can only be realized from the inside of the gate, d. i.e. from the Side where the actuator located, which is extremely disabling is when the fence closed by the gate is not a door in the gate includes that independently open can be.

To solve this problem includes the actuator according to the invention in a preferred embodiment of one of the movable plate carried lock, at least to the latter seen from the outside accessible is, this lock is designed to on the control member of the locking mechanism to be able to act and the bolt from the closing plate to free.

You can see in the 1 a part of a gate which comprises a movable wing V which is mounted on a pillar P by means of hinges G. In the closed position, this wing strikes a block fastened in the floor.

It is equipped with a motorized actuating device which, in the exemplary embodiment shown, has an arrangement of a motor reduction gear 10 includes that of a fitting 12 worn by any suitable means ( 2 and 3 ) is attached to the wing.

The motor reduction gear forming an actuating element is about an axis 14 hinged to the fitting and comprises a bracket at its end opposite the end where the linkage is located 16 who has a tie 18 delimits, the bar being formed by a rag in which a notch 19 is incorporated.

The fitting that carries the motor reducer 12 is at its end 20 bent over a locking plate or locking cap 22 to form part of a locking mechanism of the type used in the seat belt of vehicle belts or any other mechanism performing the same function. The mechanism forming this locking plate is known per se and is therefore not described in detail. A description of such a mechanism can in particular be found in documents DE-A-19 38 380, SE-A-38 97 98, DE-27 54 389, WO-80/00404, FR-A-20 349 296, FR-A- 2,379,995, FR-A-2,509,969.

It is only stated that this bracket comprises a blocking element, which with the bolt 18 can work together by using the notch incorporated in this bolt 19 engages, as well as a control button 24 which allows the locking member to disengage and release the latch, a spring also being provided in the locking cap or striker plate to push the latch back when released. These mechanisms are designed to be able to withstand relatively large tensile forces which occur between the bolt and the striker plate, and for the actuation of the control button and releasing the bolt to keep the necessary force small and preferably to keep it essentially constant.

The actuator is articulated by two in a known manner 27 connected arms completed, the first of which 26 firmly with the output shaft 15 the arrangement motor-reduction gear is connected while the other 28 on the fitting 30 at 29 is articulated, which itself is attached to the pillar.

The operation of such a device is as follows: the motor reducer is in normal operation 10 by means of a locking mechanism 18 . 22 firmly with the fitting attached to the wing 12 connected as it is in 2 is shown. The opening and closing of the wing is realized by supplying the motor reduction gear and by rotating its output shaft in one direction or the other.

In the event of a defect due to any malfunction of the device or its electrical supply, the user can disconnect this device simply by pressing the control button 24 of the locking mechanism presses. The engine reducer 10 can thus be around the joint 14 rotate. Although a hanging force is exerted between the latch and the striker plate, the actuation of the control button can be performed without force, which well solves the problems encountered with the prior art devices.

In the 4 and 5 is part of the actuator of the same general type as used in connection with the 1 to 3 has been described, but which includes an additional improvement. This is because the wing has a lock 40 is equipped, which is arranged in the vicinity of the locking mechanism, which lock can be actuated by means of a key, seen from the outside to the wing V. The castle 20 includes a body 42 attached to the wing and a cylinder 44 using a cable 46 with the control button 24 of the locking mechanism is connected.

The lock used is of a type known per se, in which in the closed position the cylinder is firmly connected to the lock body, while in the open position this cylinder is detached from the body and can be pulled out, as in the 5 is shown.

The operation of this device is very simple: while in the embodiment of the 1 to 3 the actuator can only be disconnected from the inside, the user can by means of the presence of the lock 40 In the event of a defect, open the lock as seen from the outside towards the sash, the detachable cylinder 44 pull out and by means of the cable 46 exert a train that has the effect that the control button moves and releases the bolt from the striker plate, as in the 5 is shown.

The 6 to 8th show another embodiment of a device according to the invention. One finds in this figure a part of a gate with a movable wing V, which is hinged to a pillar P by hinges G. The actuating device, the design of which is known, comprises a support fixed to the pillar P. 50 , one on this support around an axis 54 articulated arm 52 , an angle arm 56 who on the one hand at 57 on the arm 52 and on the other hand by means of an axis through a mandrel 59 ( 7 ) is realized on a fork head 58 is articulated.

The joint 57 between the arm 52 and the angle arm 56 comprises a drive mechanism of the type with gear and worm, the latter being driven for rotation by an electric motor, not shown, which, for example, in the carrier 50 or the arm 52 is stored. Such drive means form an actuating element. They are also known and are therefore not described in detail.

The end of the angle arm is on the clevis 58 by means of the mandrel 59 hinged in the normal functioning of the device in a first set of openings 60 is incorporated, which are incorporated in the legs of the fork head ( 8th ). According to a particular feature, which will be explained later, the fork head preferably comprises a second set of openings 62 in which the mandrel can be received around the location of the hinge axis between the arm 56 and move the clevis.

The clevis 58 is on a sliding shoe 64 stored, which has the shape of a U and which is fixed with a tab forming a bar 66 is connected, this bolt near its free end a notch or a hole 68 having. The sliding shoe 64 is in a slide rail 70 added, which is attached to the wing. This slide rail is formed by a profile with a rectangular cross section, the surface facing the actuating device 71 at 72 is cut out to indicate the passage and displacement of the clevis 58 to enable. This cutout 72 is open at the end of the slide that is farthest from the pillar, as in the 7 you can see.

Inside the slide rail 70 is the locking plate 74 forming part of a locking mechanism attached ( 8th ) which, as in the previous embodiments, is of the type used for the seat belt brackets for vehicles. This locking plate or locking cap 74 is by means of a screw 76 attached and by a cut and bent part 78 the slide rail 70 blocked and centered. The closing cap 74 is through a part 80 completed in the form of a bracket, the two longitudinal webs 81 two folded edges near its ends 82 around grasp that on the control button 84 of the locking mechanism come into engagement.

The device is a lock 90 of the European cylinder type, this lock being of sufficient length to reach through the slide and to be accessible from the inside and outside of the wing. The lock extends in an empty space between the locking cap 74 of the locking mechanism and the connecting bridge 83 of the bracket 80 , and it is arranged so that its flexible beard 92 , which is actuated during the rotation of the key and the cylinder, in contact with the connecting web of the bracket 80 comes, pushes the latter back and so the control button 84 shifts.

The operation of such a device is as follows: when the gate is in the closed position, the actuating element exerts a certain force which pushes the wing against the stop shoe 6 suppressed. This hanging force is necessary in order to avoid the games and the rebound of the wing as well as the noises that result from it. If for any reason the device becomes defective, the user can move the bracket 80 and pressing the control button 84 of the locking mechanism when it locks 90 actuated, this actuation has the effect that of the sliding shoe 64 worn latch 66 free and consequently uncouple the wing actuating device. It is thus easy to open the latter, with the slide shoe and the clevis protruding from the slide rail through the open end of the cutout 72 let solve. The lock can be operated from the inside or from the outside.

In order to couple the actuating device to the wing again, it is sufficient for the user, the sliding shoe 64 in the slide rail 70 and slide the sash into the closed position until the latch 66 back into the locking cap 74 of the locking mechanism engages.

To simplify this operation, before closing the wing, it is appropriate to place the hinge axis between the angle arm 56 and the shoe 64 to move by the thorn 59 is removed and in the second set of openings 62 that in the clevis 58 are incorporated, is used. The position of the second set of openings in the hinge is chosen to account for the games eliminated when the device is in the hanging position with the wing closed.

The 9 to 12 represent a variant for the arrangement of a pivot axis, which is described and which can take two positions.

In this variant, the means which take account of the games which are released during the uncoupling of the actuating device are integrated in the locking mechanism with the bolt and locking plate. In order to simplify the identification of the different parts, the parts that come from the 7 and 8th correspond in the 9 to 12 with the same reference numbers, increased by 100 Mistake.

You can find a glide shoe 164 again, the one bar 166 carries and slides in a slide rail 170 is included. This bar has two holes or notches 168 . 169 instead of that of the embodiment of FIG 7 and 8th ,

The locking plate or locking cap 174 is from a carrier 175 worn, even on the slide rail 170 is attached. This locking cap includes a control button 184 and a blocking device 173 that with a hole 168 can work together. Between the bottom of the slide rail and the carrier 175 a second blocking member is arranged by an elastically deformable metallic tongue 20 is formed, which has a hook at one end 202 with a second hole 169 of the bolt can work together, and a rag at its opposite end 204 which can work with the beard of a castle, which is optional, however. This castle 119 is in the 9 shown in dash-dotted lines.

The tongue 200 also includes two side tabs 206 which extend substantially perpendicular with respect to their plane and which are in two side recordings 208 the control button 184 are included.

The tongue 200 is thus firmly connected to the control button translationally in accordance with a direction parallel to the direction of displacement of the bolt with respect to the locking cap.

The operation of such a device is as follows: In the position of the 9 the bolt is in the approaching position before it is latched into the locking cap. This latching position is in the 10 shown in which you can see that the blocking member 173 in the hole 168 of the bolt engages. The blocking hook 202 is thus neutralized elastically under the bar.

In the position of the 11 the latch is locked by the cooperation of the hook 202 with the second hole made in the bolt 169 receive. This position of the bolt is offset from the previous one by a distance d, which corresponds to the value of the games that are released during the uncoupling of the actuating element.

This decoupling corresponds to that in the 12 illustrated situation in which the control button 84 to the right of the drawing, at the same time as the tongue 200 what has the effect, the hook 202 neutralize by a ramp effect that is between the front edge 175a of the carrier 175 and the inclined part 201 the tongue 200 occurs. The bar is therefore one or the other of the two blocking members freed and can move to the left in the drawing to then detach from the slide, as already in connection with the 6 to 8th was explained.

Pressing the control button 184 can be implemented manually by pressing this button directly or by means of a lock 190 , whose agile beard angularly towards the end 204 the tongue works.

• – Die Abkopplung der Betätigungsvorrichtung wird extrem leicht gemacht durch die Verwendung eines Verriegelungsmechanismus und Entriegelungsmechanismus, bei dem die notwendige Kraft während der Betätigung der Entriegelung gering ist und praktisch unabhängig von der Hängekraft, die von der Vorrichtung ausgeübt wird;
• – Dieses Ergebnis wird erhalten, indem ein Mechanismus verwendet wird, der anderweitig in anderen völlig unterschiedlichen Anwendungen bekannt ist und der, da er in einer großen Serie hergestellt wird, relativ geringe Kosten aufweist. Die Anpassung der Vorrichtung für die Einbettung eines solchen Mechanismus ist relativ einfach und wenig kostenaufwendig;
• – Wenn der Verriegelungsmechanismus einem Schloss zugeordnet wird, das, sei es von außen oder von innen und außen von dem beweglichen Verschlusselement gesehen, zugänglich ist, wird ein zusätzlicher wesentlicher Vorteil erhalten, da der Benutzer sehr einfach die Betätigungsvorrichtung sowohl von innen als auch von außen des Tors leicht abkoppeln kann;
• – In den Ausführungsformen der 6 bis 8 und 9 bis 12 kann die Betätigungsvorrichtung in der Benutzungsstellung und in der Blockierstellung einge setzt werden, da aufgrund der Berücksichtigung der Spiele, die bei der Abkopplung freigesetzt werden und die üblicherweise durch die in der Schließstellung ausgeübten Hängekraft resorbiert werden. Wenn der Gleitschuh einfach in die Gleitschiene wiedereingesetzt wird, kann der Benutzer dann, wenn er zum Tor gesehen außen ist und dieses letztere schließt, die Wiederverriegelung des Riegels hervorrufen, ohne direkt auf den Mechanismus einwirken zu müssen.

It follows from the preceding description that, in its different embodiments, the device according to the invention offers significant advantages with respect to the arrangements according to the prior art:

• - The decoupling of the actuating device is made extremely easy by using a locking mechanism and unlocking mechanism, in which the force required during the actuation of the unlocking is small and practically independent of the hanging force exerted by the device;
• This result is obtained using a mechanism which is otherwise known in other completely different applications and which, since it is manufactured in a large series, has a relatively low cost. The adjustment of the device for embedding such a mechanism is relatively simple and inexpensive;
• If the locking mechanism is assigned to a lock that is accessible, be it from the outside or from the inside and outside of the movable locking element, an additional significant advantage is obtained since the user can very easily operate the actuating device both from the inside and from the outside can easily disconnect the gate;
• - In the embodiments of the 6 to 8th and 9 to 12 The actuating device can be inserted in the use position and in the blocking position, because due to the consideration of the games that are released during the uncoupling and that are usually absorbed by the hanging force exerted in the closed position. If the slide shoe is simply reinserted into the slide rail, the user can, when he is facing the door and closes the latter, bring about the relocking of the bolt without having to act directly on the mechanism.

This possibility of relocking without size Power and from the outside undoubtedly represents a very great advantage of the device according to the invention.

Of course, analog or equivalent means in the embodiment of the 1 to 5 be provided in order to be able to easily re-lock the gate in the closed position.

The invention can be used with any actuator of gates or the like be used, however the type of actuator used may be hydraulic or electromechanical and whatever the kinematics the means may be the gate with the fixed structure on which it's attached, connect.
