The invention relates to the field of security technology and is used for automatic closing-opening and locking-unlocking two leaf swing mostly garage doors.

The known device for closing-opening valves, which represent different ways of hinged automatic actuators (for example, patent RF №2033516, E05F 15/00, 1995, as the USSR №1470923, E05F 15/00, 1989). However, the design of these actuators is that they are for reasons of economy of materials and the desire to minimize the size have a relatively short working stroke and to open the valves at a large angle (90°...120°) interact with them through small shoulders. After closing of the gate leaf poorly pressed against the opening and not locked relative to each other in the clamping area, so do not exclude the possibility, not putting much effort to lift or bend of the leaf, i.e. the gates remain closed, but not locked.

As a rule, are used in devices in which the closing-opening of the valves by a single mechanism, such as an automatic actuator, and a locking-unlocking - other, for example an Electromechanical lock, the bolt which moves under the action of a built-in lock motor or an electromagnet. After closing the valves bolt connects them with each other in the area of note is Chania to each other. The sequence of interaction between the actuator and the lock is set by limit switches mounted on the opening of the gate and latch. This solution complicates the possibility of unauthorized opening of the valves, but is complicated due to the large number of interdependent electrical components, do not provide a firm pull of the valves for opening and prone to jamming of the bolt, if one of the valves will be badly pressed against the opening, for example, because of the falling snow.

Famous locks for gates that implement various principles, such as electromagnetic on AU of the USSR №1289977, RF patent No. 2261976, mechanical patent RF №2002927, No. 2277623.

They use separate actuators for locking devices (see RF patent №2091554, EV 47/00, 1995). In this device, the lock includes a spring-loaded bolt, clamps open and closed position, the latch comprising two pivotally connected elements and cooperating with the latch open position of the bolt, and move the bolt. The device consists of an electric motor, worm gear and Cam, an eccentric mounted on the worm wheel. When the Cam releases the bolt from the latch to its closed position and moves the bolt. The castle is equipped with an emergency release.

The disadvantage at which trojstva is its complexity.

It is also known eccentric locking device in the rear swing folds car refrigerators, containing mounted in bushings on the edge of the covering leaf, equipped with a folding handle vertical axis, on the upper and lower ends of which are protrusions that interact with the locking of the valves with counter parts, fixed on the doorway. This device tightly pulls the sash to the doorway, but only works in manual mode, not providing automatic closing-opening and locking-unlocking of the valves (see, for example, hinged doors for high-sided vehicles and trailers manufactured by group companies gird (www.gird.ru/furgon168.html). Also in manual mode work fixing the locking device tailgate of the vehicle (GR No. 54074).

The challenge which seeks the proposed solution is to automate the closing-opening and locking-unlocking of the gate simplify the design and increase the reliability of the device.

The problem is solved in that the locking device gate includes two reported with leaves through the brackets automatic drive, one of which is associated with covering the leaf through mounted with angle bracket and rod, pivotally attached at one end to the bracket and the other to a growling is, attached to installed on the edge of the sash vertical rotary axis with the handle, and the axis provided with a lower locking Cam unit having the opportunity to interact with the response item on the gates opening, and the upper locking hook with a Cam surface having the opportunity to interact with the roller mounted on the opening of the gate, in addition, on the hook, there is connected through a spring clamp with a wing of the shank to lock in the wheel.

Such structural embodiment of the device, in which:

- mounted on covering the sash bracket is limited by stops turning;

the lower locking unit is designed in the form of a hook with a Cam surface having the opportunity to interact with the movie on the opening of the gate;

- on brackets on the hinge side of the sash is made of vertical grooves, in which is mounted a removable studs for mounting drives.

The set of essential features of the proposed technical solutions using universal drive, providing both the opening-closing and locking-unlocking gate leaves, simplifies the design and provides automation of the process.

The invention is illustrated in the drawings, where figure 1 shows a top view of the swing gate in closed position figure 2 - top view of the swing gate in the open position; figure 3 - installation of the device on the gate (inside view); figure 4 is a view As in figure 1; figure 5 - callout I figure 3; figure 6 - a view B figure 5 with a locked gate; 7 - a view B figure 5 when door is open.

The device will keep two hinged automatic actuator, opening and closing doors, and locking, unlocking and locking of the sash due to the use of part of the stroke of one of the actuators. The device is hung from the inside, for example, on garage doors.

Consist of valves 1 and 2, rotating around a vertical axis hinges 3 running automatic actuators 4 and 5. On covering the sash 1 is welded strip 6, which covers the vertical gap between the doors when the door is closed, presses the shutter 2 to the opening of the gate 7 and does not allow it to open. Thus, for locking the gate enough to lock in closed position only covering the sash 1, so the auto lock is only on it (figure 3).

Each of the actuators 4 and 5 are installed on the fixed side walls of the opening of the gate bracket 8 and includes a motor, lead screw 9 and nut 10 welded to the tube 11, into which is inserted a pin 12 mounted on the bracket attached to the leaf (figure 4). When the operation of each actuator his e is tradigital rotates the screw 9, forcing the nut 10 to move, and through the tube 11 and the pin 12 and the bracket to open or close the corresponding door. Drive 5 communicates with the door 2 through the bracket 13, and performs only the functions open or close the sash 2. The actuator 4 communicates with the door 1 through the automatic lock algorithm "open-open" or "close-to lock.

Auto lock is arranged as follows. The actuator 4 his pipe 11 (figure 4) is connected to pin 12 mounted on the bracket 14, through which the hinge 15 is connected with the bracket 16 fixedly mounted on the sash 1 (6, 7). The hinge 15 allows the bracket 14 to rotate relative to the bracket 16 at a slight angle to lock into each other points and, With this rotation, the pin 12 is moved to 60...80 mm, which, as shown below, and provide a trigger lock. Pets attaching the hinge 15 directly to the sash 1 without bracket 16. In order not to clutter the drawings, figure 5, 6, 7, the actuator 4 and the bracket 8 of its fastening on the opening conventionally not shown.

With the bracket 14 via the hinge 17 are connected to rod 18, which includes a threaded sleeve 19, which serves to adjust the length of pull. The second end of the thrust has a tip 20 curved shape and through the hinge 21 is connected with the lever 22 that is welded to the axle 23. The axis 23 is vertically installed on the edge of the sash 1 andhas able to rotate in the sleeve 24. On the lower and upper ends of the axis 23 is welded to the locking hooks 25 and 26.

In the center of the gates opening at its lower and upper horizontal surfaces of the fixed rollers 27 and 28 serving to grip the hooks 25 and 26. Surface hooks that are in contact with rollers made according to the principle of the eccentric, so when running around the rollers they with increasing force pulling the flap 1 to the opening and provide a reliable locking of the gate. The shape of the upper hook 26 is different from the shape of the lower availability of the shank 29 welded to the axle 30, with which cooperates a spring clamp that is designed to bring and hold the hooks in open or closed positions. The latch consists of a rod 31 with the ring 32, the compression spring 33 and the cylindrical body 34 with two pins 35 (figure 5). The axle can be rotated located in the second grooves of the two brackets 36 mounted on the sash 1, the spring 33 presses the pin 35 to the slots of the brackets 36, holding the latch between the axle 30 and the brackets 36 in the process. When the axis of the pins 35, the axis 30 and the axis 23 are located on the same line, the spring 33 is maximally compressed and the latch is in its position of unstable equilibrium. When the offset axis 30 in either direction from this position the spring is starting to spring up through the axle 30 to rotate together with the axis 23 of the hooks 25 and 26 to their fully open and the closed positions.

The fully-open state of the hooks 25 and 26 through a chain of parts 23, 22, 21, 20, 18 is determined by the emphasis in each other points G of the brackets 14 and 16 (7), and the maximum closed - points C. In practice, the emphasis in each other points may not be achieved (6)if the hooks stop a little earlier when you achieve a snug fit of the sash 1 to the opening 7 of the gate, which is provided by adjustment of the actuator 4. Instead of the lower hook 25 and its corresponding roller 27 may use the lower eccentric locking node in another construction of interacting with a return item for opening the gate.

To be able to disconnect the actuator from the bracket 13 and 14 (for example, when electric power is off) pins 12 are removable and are attached to the brackets by screws 37, which are wrapped in brackets on the hinge side 3 (Fig.7). Such arrangement of the screws 37 provides parallelism or small angles between the axes of the screws 37 and driving screws 9 drives and allows you to disconnect the drives on the locked gate, loosening loosening of screws 37 created drives the tightness of the valves, or Vice versa, to attach to shutters bezel drives, restoring when tightening the screws 37 a tight fit shutters to the doorway. To the trunnion 12 to better transmit the lateral components of the efforts of the actuators and to eliminate the deviation of C is PF from the vertical position due to the gradual weakening of the tightening of the screws 37 during long-term operation of the gate under the action of vibration operating drives and fluctuations of the wings with the wind in the process of opening and closing, the brackets are made of vertical cylindrical grooves 38, which are placed and are attracted by screws 37 cylindrical base pins 12.

For locking and unlocking the gate using the described lock in manual mode when turned off and power is disconnected from the valves actuators to the axis 23 is welded to the sleeve 39, which is threaded axis 40 of the handle 41 (Fig 3). Under the action of gravity arm 41 is freely hanging parallel to the axis 23, without creating obstacles in the area of the valves.

The device operates as follows.

When the gates are open (figure 2), parts of the castle are in the positions shown in Fig.7, the brackets 14 and 16 contact points G, the spring pin through the axle 30 has rotated the axis 23, and with it the lever 22 to the stop lug 20 in the axis 23. In addition, the line connecting the hinges 21 and 17, is at a distance D behind the axis 23 (in practice, D=1...3 mm), the hooks 25 and 26 are open.

When the feed control gate commands to the closing, to avoid collision of the valves first starts to close the door 2. After about 5...10 seconds (when the door 2 rotates 20°...30°) begins to close and the shutter 1. The actuator 4 through the trunnion 12 and the bracket 14 pulls it over the rod 18, and the tip 20 due to the negative of the shoulder On the actuator thrust is pressed to the axis 23, which prevents longitudinal movement of draw rod 18 and premature rotation of the hooks 25, 6. The shutter 2 of the first concerns of the opening and stops; the moment it is stopped is determined by the adjustment of the actuator 5. After 5...10 seconds to the doorway approaching the door 1 and the shank 29 abuts against the roller 28 (Fig.7). The drive continues to close the sash 1 and the pressure roller 28 on a shaft 29, the hook 26 starts to rotate clockwise, compressing the spring 33 of the latch, and together with the hook 25 captures the rollers 28 and 27. The rotation of the hook 26 by the shaft 23 causes to rotate clockwise the lever 22, and the tip 20 moves away from the axis 23 and the distance D is gradually reduced to zero. Further, the hinge 21 crosses the line connecting the hinge 17 and the axis 23, and from this moment, the lever 22 continues not only due to the pressure roller 28 on a shaft 29, and also due to the positive leverage On and made possible by the longitudinal displacement of the actuator 4 thrust 18. Then turn hooks starts to help and the latch spring 33 which begins to spring up after passing through a position of unstable equilibrium. As you rotate the lever 22, the shoulder D increases, which together with the eccentric shape of hooks provides a significant increase in the pressing force of the leaf to the doorway at a constant force actuator 4. The bracket 14 is rotated clockwise relative to the bracket 16, the point G stop contactor is obtained and removed from each other. Final closing and locking doors 1 occurs when the hooks grab the rollers at the desired depth, both wings firmly pressed against the aperture and the nut 10 of the actuator 4 will stop in a predetermined position on command from a remote control gate (6). Application in the design of the lock tip 20 curved shape is the most rational, but not the only solution. This is the same function of converting the translational movement of the thrust 18 in the rotation axis 23 can be implemented by other parts of the geometry.

Opening of the gate is as follows. On command from a remote control gate first opens the shutter 1. The movement of the screw 9 and nut 10 of the actuator 4 in the first stage can not open the door, because it is held by the hooks, but through the journal makes 12 to rotate counterclockwise bracket 14 relative to the bracket 16, causing convergence points G (6, 7). The rotation of the bracket 14 through the rod 18 and the lever 22 causes the pivot axis 23 with hooks 25, 26. Hooks gradually disengage from the rollers 27, 28 and pivoting the hook 26 through the axis 30 compresses the spring 33 of the retainer. In the process of turning of the lever 22 the axis of the hinge 21 is approaching the line connecting the axis of the hinge 17 and the axis 23, and crosses it, and the shoulder D is first reduced to zero and then becomes negative (Fig.7). The latch passes through p is a position of equilibrium, the spring 33 begins to spring up and over the axle 30 rotates the axis 23 and the lever 22, bringing the tip 20 is fully inserted in the axis 23 and maximum opening and holding in this state, the hooks, the point G start to touch.

Further opening of the sash 1 is already without the participation of the thrust 18 and its associated parts, and only due to the pressure of the actuator 4 through the pin 12 to the bracket 14 and through the point G on the bracket 16. Force transmission through the points G unloads rod 18 from the longitudinal compression forces during movement of the sash (when she can meet any obstacle, stone, snow, etc. and the force of the actuator to the door sharply) and allows to make it more subtle. The castle remains operable, if the draught regulation 18 through the sleeve 19 tip 20 has already touched the axis 23, and the point G is not yet in contact (the length of the rod more required) or if the bracket 14 when the manufacturer does not specifically provided for limiting rotation and between points G remains a gap. In these cases, the opening of the door will be happen in normal mode, but only due to the impact of the actuator 4 through the parts 12, 14, 17 along the thrust 18 on the axis 23 that loads longitudinal traction power compression and tends to increase its diameter in the manufacture.

After the shutter 1 will turn 20°...30°, approximately 5...10 seconds starts to open the door 2. This time the Itza in time to avoid snagging and jamming of the valves in the area of the strap 6. Stop valves in the open position (figure 2) occurs on command from a remote control gate upon reaching each leaf of the desired opening angle.

If you disable the electricity drives the gate will not allow you to open and close the shutters manually. If the electricity is turned off at the locked gate, then fold with tightness drawn to the doorway and drives their tubes 11 with great effort put pressure on the trunnion 12. Thanks to the detachable design of the pins and their location on the hinge side 3 by unscrewing the screws 37 there is a gradual reduction and termination of the pressure tube 11 on the axle 12, which allows you to remove the pins from the brackets 13 and 14, take them out of the tubes 11 and disconnect the drives from the valves, which then can be opened or closed manually.

If the electricity is turned off when open or half-open gate, the pressure tube 11 on the axle 12 is missing and disconnecting the drives from the valves is easier due to the lighter screws 37.

If necessary, unlock or lock the gate in manual mode when disconnected the actuator arm 41 is rotated by hand relative to the sleeve 39 to approximately a horizontal position and it turns the axis 23, and with it the hooks 25, 26 that extend or enter into engagement with the rollers 27, 28 and release or lock the sash 1. Pru is ion battery latch provides communication to the stop and hold the hooks in an open state when the vehicle is unlocked gate. When the locking gate latch helps the handle 41 to close the hooks and pull the sash toward the opening, and then holds them in this position, not allowing the gate to open when accidental or intentional fluctuations shutters.
