When the hook 32 is inserted more than a predetermined distance (that is, when the lower end of the lock 21 is beyond the curved portion of the hook), the lock 21 is lowered by its own weight (hook) 32 Will be fixed.

The hook 32 is to press the reaction means (40) when inserted into the through hole 11, the hook 32 is caught by the locking hole 21 to lock the door, the reaction means (40) Waits for the hook 32 to press forward. That is, the reaction means 40 in a pressurized state has a force to push the hook 32.

When the user operates the solenoid 80 through the control unit in order to open it in the state in which the sliding door 1 is closed, the lock 21 coupled to the solenoid 80 is raised, and the lock 21 By the lifting of the lock 21, the hook 32, which has been restrained by the forward movement, is released.

At this moment, the hook 32 is pushed forward by a predetermined distance by the elastic force of the reaction means 40, and the user grips the handle 31 provided on the swing door 1 to open the swing door 1 Will open.

The reaction means 40 is composed of an elastic body 41 that is pressed by the hook 32 to enter and a portion of the elastic body 41 is inserted into the buffer portion 42 which is in contact with the hook 32, the hook ( It absorbs the shock generated when the 32 enters to prevent the shock from being transmitted to the door frame 2, and furthermore, the elastic force of the elastic body 41 is intact on the hook 32 when the opening door 1 is opened. It serves to be delivered.

In the present invention, the anti-theft frame 100 may also function as a door frame (2), it is also possible to be firmly mounted with a screw or the like in addition to the existing door frame (2). When installing the anti-theft frame 100 according to the present invention to the existing door frame 2, the jaw having a height corresponding to the thickness of the anti-theft frame 100 is protruded from the door frame (2) The bent portion 30 is formed on the handle 31 to be formed, and the hook 32 is provided at the rear of the bent portion 30 in contact with the crime prevention frame 100.

The shock absorbing portion 42 may be made of various materials. It is preferable to use a rubber or urethane having a property of returning to the original state in a deformed state by absorbing shock and absorbing an impact, and the shock absorbing portion 42 includes an elastic body. A portion of the 41 is further provided with an insertion groove 43 is fixed.

In addition, the recoil means 40 is to be disposed in a position that is not caught when the lock 21 is moved up and down for this purpose, the recoil means 40 is disposed on the rear lower side of the lock 21 and the front It is supported in contact with the rear surface of the lock 21 in the protruding state.

The upper side of the lock 21 is provided with a second locking device (A2) for limiting the vertical movement of the lock (21).

The second locking device (A2) is provided on the upper side of the lock (21) and is fixed to the lock device (50) provided with a hollow 51, the lock device (70) provided in the security frame (100) It consists of the latch 60.

The movement limiter 50 is to move up and down in conjunction with the lock 21, made of a '⊃' shape toward the front panel 10 of the crime prevention frame 100, the locking mouth 60 is provided to be movable up and down by the lock device 70 provided in the crime prevention frame 100 and is located in the hollow 51 of the lock 21.

When the user operates the first locking device A1 to open or close the swing door 1, the lock 21 moves up and down and the movement limit fixed integrally on the upper side of the lock 21 is limited. The sphere 50 is also moved up and down at the same time.

However, the position of the movement limiter 50 may be limited by the movement of the locking hole 60, the locking hole 60 located in the hollow 51 of the movement limiter 50 is the movement limiter 50 Raising and lowering of the movement limiting means 50 is limited (of course, the raising and lowering of the lock 21 is also limited) depending on whether located above or below the hollow 51 of the hollow.

For example, in order to open the swing door 1, as shown in Fig. 6, the locking hole 60 of the second locking device A2 must be located above. If the locking hole 60 of the second locking device A2 is located below, as shown in FIG. 7, the lower inner surface 52 of the movement restrictor 50 is the locking hole 60. ), The movement restrictor 50 and the locker 21 cannot rise even when the solenoid 80 is operated by the control signal of the control unit of the first locking device A1.

Here, the lock device 70 is sufficient if the structure to change the position of the locking hole 60 up and down by using a key, attaching the rack to the locking hole 60, by forming a pinion on the key bundle side It can also be configured, it is also possible for those skilled in the art to sufficiently predict that the locking mechanism 60 is eccentric to the rotation axis of the key bundle.

In addition, as shown in FIG. 8, the security frame 100 is fixed to the upper part of the door frame 2, and the bent portion 30 provided with the hook 32 corresponds to the security frame 100. Coupled to so that the security frame 100 can be selectively fixed to the upper or side of the door frame (2) according to the installation environment and location of the door frame (2).

Hereinafter, the operation of the present invention will be described.

When the sliding door 1 is rotated toward the door frame 2 to close the entrance and exit, as shown in FIG. 2, the bent portion 30 coupled to the handle 31 comes into contact with the crime prevention frame 100. The hook 32 provided in the bent portion 30 is inserted into the through hole 11 of the crime prevention frame 100 to push up the lock 21 to the upper portion and at the same time to press the reaction means 40 backward. do.

The hook 32 and the lock 21 are formed with a rear bent portion 33 and the front bent portion 22, respectively, the upper portion of the lock opening 21 by the force that the hook 32 is in contact with each other. It is pushed up smoothly.

When the hook 32 passes through the front curved portion 22 of the lock 21, the lock 21 moves downward by the weight of the hook 32, and the lock 21 is hooked. Since it binds (32), the door is eventually locked.

That is, the hook 32 is to move the lock 21 to the upper by the force to enter and at the same time to press the reaction means 40, after the hook 32 has entered a predetermined distance or more the lock (21) is lowered by its own weight, so that the jaws of the hook 32 is caught by the lock 21.

At this time, the hook 32 is pressurized to the reaction means 40 while entering the interior of the crime prevention frame, the pressurized reaction means 40 continues to act as a force to push the hook 32 in the locked state Even if the user does not open the door 1 by holding the handle 31, the hook 32 is moved forward by the restoring force of the reaction means 40 at the moment when the lock 21 is raised by the door open signal. It is convenient because it is opened by a predetermined distance as if bounced.

Furthermore, a double locking function may be given by using the lock device 70 provided above the crime prevention frame 100.

That is, as illustrated in FIGS. 2 to 6, when the locking device 60 fixed to the locking device 70 is located above, only the configuration of the first locking device A1 may be locked / opened.

If necessary, there may be a case in which the locking device needs to be operated in a double manner. For this case, in the present invention, as shown in FIG. 7, the opening and closing security door (access door) is configured as shown in FIG. 7. ), The double locking effect can be obtained very simply by simply switching the locking hole 60 of the lock device 70 downward.

That is, when the locking hole 60 of the second locking device A2 is located below, since the lower inner surface 52 of the movement restrictor 50 is in close contact with the locking hole 60, 1 Even when the solenoid 80 is operated by the control signal of the control unit of the locking device A1, the movement restrictor 50 and the locker 21 cannot rise, so that the security card (IC card or R / F card) There is an advantage that can strengthen the security to prevent the door opening alone.

The process of opening the double locked door 1 is also not very different from the process described above. That is, in order to raise the lock 21 to the position beyond the jaw of the hook 32, first release the lock device 70 provided in the anti-theft frame 100 to raise the position of the latch 60 upwards After moving to allow the movement limiter 50 to move upward, the solenoid 80 is operated by operating a control unit with a security card (IC card or R / F card) or a switch.

When the lock 21 is raised by the opening signal of the door, the hook 32 is bounced forward by the restoring force of the reaction means 40 even if the user does not hold the handle 31 to open the door 1. Will open.

As described above, the door-to-door security structure according to the present invention is not only capable of opening and closing operation with the first locking device A1, but also selectively operating the second locking device A2 as necessary to ensure a double locking function. It is possible to implement a more secure security structure of the swing door (1).

In addition, by combining the bent portion 30 provided with the anti-theft frame 100 and the handle 31 according to the present invention to the conventional swing door can be easily obtained a swing door having a security structure consisting of a double locking means The security of the door can be strengthened, but the installation cost can be reduced, thereby reducing the installation time and having an economically useful effect.

While the security structure of the swing door according to the present invention has been described above with reference to the accompanying drawings, the present invention is not limited to these descriptions and various modifications and changes by those skilled in the art within the scope of the idea of the utility model registration claims attached thereto.
