The DC motor (M) attached to the bottom plate 4 of the inner side of the vault door 2 and opening and closing the vault door 2 as a hinge 3 without a handle on the vault door 2 of the vault 1. The normal controller (C) connected to the installation is operated by a separate remote control (R), so the DC motor (M) is installed to operate.

On the side where the bottom plate 4 is attached to the rectangular frame 5 of the inner side of the vault door 2, the latch 6 is fixed to the latch fixing plate 7 in a row and inserted into the hole 8 to one side. It was installed so that the latch 6 can be inserted into the fastening groove 10 formed in the body of the safe 1.

In addition, the upper surface portion 11 ′ of the connecting plate 11 of the latch fixing plate 7 made of the same plate body as the latch fixing plate 7 is provided with a relief piece 12 fixed in the bottom plate 4 by a cut-out hole. A spring 15 is installed between the fixing pieces 13 bent at the end of the portion 11 'so that the spring 15 is elongated when the latch 6 is reversed and the spring 15 is extended. This contraction return action.

In addition, the position of the reducer 18 which is installed on the DC motor M at a position adjacent to the engaging piece 9 bent at the upper surface portion 11 'of the connecting plate 11 for the reverse release action of the latch 6. Fixing the tack rods 17 on the installation of the latch reverse cam 16 on the rotating shaft 18 ', while pushing the latch 9 to the left while the latch reverse cam 16 rotates 360 degrees. As the spring 15 is extended, the latch 6 is released backward.

In addition, the pin 20 fixed on the bottom plate 4 on the upper surface portion 11 ′ of the connecting plate 11 of the latch fixing plate 7 which is overlapped on the bottom plate 4 so as to flow in a double manner. The type safety piece 21 is horizontally installed on the surface, but the receiving groove 23 is caught by the end 24 'of the bending extension piece 24 by receiving the elasticity of the coil spring 22. The projection (16 ') at the time of 360 degree rotation of the reverse cam (16) Since the relief portion 26 of the type safety piece 21 is quenched, the coil spring 22 is extended so as to move forward from the end portion 24 ′ of the bending extension piece 24 and to allow the cladding 6 to move forward and guide. It was.

In addition, the present invention forms a hole jaw (27) in the lower part of the fixing plate (7) in order to maintain a stationary state after the latch 6 is released and the lower surface portion (11 ″) of the connecting plate 11 of the fixing plate (7) With pin 30 fixed on bottom plate 4 on top The hook-type hook piece 31 is rotatably installed so that the hook piece 31 and the upper catching jaw 31 ′ are caught when inserted into the hole jaw 27, and the lower support piece 31 ″ has a rectangular frame 5 and The end portion in which the push rod 29 is inserted through the holes 28 and 28 'bored in the lower surface portion 11 ″ is placed in contact with the support piece 31 ″. A coil spring 32 was elastically installed on the mold hook piece 31.

This is because one side end of the push rod 29 is slightly exposed to the outside of the rectangular frame 5 so that the exposed portion 29 ′ touches the safe 1 wall when the safe door 2 is closed, exposing the push rod 29. As we push part (29 ') While extending the coil spring 32 elastically installed on the mold hook piece 31, the upper catching jaw 31 'of the hook piece 31 is rotated to move away from the hole jaw 27, so that the forward rule of the latch 6 is improved. It can be configured.

In addition, between the fixing piece (34) (34 ') standing on the bottom plate (4) on the top of the rectangular frame (5), the front and rear vibration bars (35) are installed to receive the elasticity of the spring 36, so that the end (35') of the rectangular frame ( 5) The end 35 'comes into contact with the side wall of the vault when the vault door 2 is closed by installing it to be slightly exposed to the outside of the hole 37 of the vault, so that the spring 36 is contracted and the vault 6 is released. (2) was configured to open automatically under the spring force of the spring (36).

When the present invention as described above is pushed to close the handleless door (2) by hand and pushed the button using the remote control (R) of Figure 2 in the state where the latch 6 is advanced and inserted into the locking groove (10). An electronic current flows to the normal controller C installed on the fixing plate 4 inside the rectangular frame 5 inside the vault door 2 without a handle to operate the DC motor M.

At this time, the rotary shaft 18 'of the reducer 18 connected to the DC motor M shaft rotates the latch reverse cam 16 fixed to the rotary shaft 18' at a low speed rotation and rotates the latch reverse cam 16 at the same time. Relief piece 12 because the tack rod 17 fixed to the upper side pushes the engaging piece 9 in which the connecting plate 11 and the upper surface portion 11 'of the fixing plate 7 are integrated to the left. At the same time the spring (15) is elastically installed between the fixing piece (13) and elongated at the same time fixed to the latch fixing plate (7), the latch (6) is released from the insertion groove (10) is released and released.

At the same time as the release of the latch 6, the vault door 35 is installed between the bottom plate 4 and the upper fixing piece 34, 34 'to receive the elasticity of the spring 36 when the vault door 2 is closed. By closing the vault door 2, the spring 36, which has been contracted, acts as a shot, so the vault door 2 is automatically opened.

At this time, the pin 30 is installed to receive the elasticity of the coil spring 32 on the lower surface portion 11 ″ of the connecting plate 11 of the fastening plate 7 at the same time. The catching jaw 31 'of the hook-type hook piece 31 is in a state of being detached from the hole jaw 27 of the latching plate 7 and the coil spring 32 contracts due to the backward movement of the push rod 29. Under elasticity Since the hook 31 is rotated from the pin 30 as a starting point, the latching jaw 31 'of the hook 31 is inserted into the hole jaw 27 drilled into the fixing plate 7 so that the latch 6 is held. It will hold the unlocked state and keep it.

When the vault door 2 is opened and closed by hand, the lower push rod 29 exposed portion 29 'and the upper and rear push rod 35 end 35' touch the inner wall surface of the safe 1 at this time. The push rod 29 Since the support piece 31 ″ of the hook type piece 31 is pushed out, the hook piece 31 extends the coil spring 32 from the pin 30 as a starting point, and the hook piece 31 from the hole jaw 27. Since the latching jaw 31 'of the bar comes out as shown in Figure 5, the latches 6 fixed in a row to the latch fixing plate 7 by the elastic action that the spring 15 in the extended state is contracted (safe) ( 1) It is inserted into the ruled groove 10 formed on the body wall surface.

In addition, when the latch fixing plate (7) fixing the bar (6) when the forward action, the bending extension piece (24) formed integrally with the latch plate (7) also has the same forward action as the pin 20 to the bottom plate (4) Installed The mold safety piece 21 is caught by the engaging groove 23 being inserted into the end 24 'while the coil spring 22 is elastic due to the forward movement of the end 24' in place.

therefore The locking groove 23 of the type safety piece 21 supports the end portion 24 'and prevents the reverse of the latch fixing plate 7 integrated with the bending extension plate 24, so that the latch 6 is retracted by the other. If you try to force the freeze is not freed, so you can use a safe safe.

As such, the present invention releases the latch 6 using the remote control from the outside of the safe door 2 without a handle, and when the latch 6 is released, the safe door is automatically opened as well as the hand when closing the safe door. Since the door is closed, the opening and closing of the safe door is easy and the latch 6 is inserted into the locking groove 10 at the same time. The type safety piece 21 stops the reverse of the latch 6, so that even if it tries to forcibly operate the shock or the backward of the bow, it becomes a safety device and can use a safe safe.
