Description

  The present invention relates to a door lock device that locks a single-open outer door disposed on the front face of a vending machine to a closed position.

As a door lock device for vending machines, it has a lever-handle-type lock mechanism with a single-open outer door located on the front of the main cabinet, and a vertically movable slider lock linked to the swing cam of the lock mechanism. In a locked state with the door closed, a configuration in which the slider lock is locked to a latch provided on the front surface of the outer box of the main body cabinet and the outer door is locked in the closed position is well known (for example, a patent Reference 1).
In addition, as a measure for protecting the door lock device having the above-described structure from vandalism and improving the anti-theft property of the vending machine, an anti-theft cover is attached to the side edge of the door lock side of the outer door and the outer box of the main cabinet. The thing of the structure which covered the clearance gap between these from the outside is also known (for example, refer patent document 2).
Japanese Patent No. 3146820 Japanese Patent Laid-Open No. 11-53631

By the way, even if an anti-theft cover is additionally provided as a measure for protecting the door lock device from the destructive action, it cannot be said that the destructive action using a tool such as a bar or an electric saw is sufficient. Therefore, in the past, anti-theft measures have been taken such as providing an independent lock with a lock separately from the door lock device, or locking the door double by locking the outer door and the main body cabinet with a chain. ing.
However, with these anti-theft measures, each time the door is opened and closed, each door lock must be individually unlocked and locked, which is cumbersome to operate. Moreover, since the installation location of each door lock can be seen at a glance from the outside, there is also a problem that it is easy to receive a vandalism aiming at the door lock.
The present invention has been made in view of the above points, and its object is to solve the above-mentioned problems, and to provide an auxiliary lock that engages and releases in conjunction with the main lock mechanism of the outer door, and includes an outer door and a main body cabinet. Another object of the present invention is to provide a door lock device for a vending machine that is double-locked and prevents the presence of an auxiliary lock from the outside, thereby improving the anti-theft and operability.

In order to achieve the above object, according to the present invention, an outer door is provided with a lever handle type lock mechanism with a lock and a vertically movable slider lock linked to a swing cam of the lock mechanism, and the door is closed. In the door lock device of the vending machine in which the slider lock is locked to a latch provided on the front of the outer box of the main body cabinet and the outer door is locked in the closed position in the locked state.
As a lock backup means for the outer door, an auxiliary lock that is engaged with and released from the outer box of the main body cabinet in conjunction with the handle operation of the door lock mechanism is provided at a position different from the latch. There is no lock plate which is arranged on the back side of the door and linked with the slider lock, and is guided and supported so as to be slidable left and right to the release position by following the vertical movement of the slider lock. The lock plate is locked to the front edge of the outer box of the main body cabinet from the inside in the closed locked state (Claim 1).

In the above configuration, the guide means for moving the auxiliary lock between the right and left locking positions and the release position in conjunction with the vertical movement of the slider lock can be configured in the following embodiment.
(1) The linkage leg piece provided on the lock plate is linked to the slider lock through the guide groove hole in the inclined direction formed on the back surface of the outer door, and the lock plate is moved to the left and right engagement positions in conjunction with the vertical movement of the slider lock. , Advance and retreat to the release position (claim 2).
(2) Contrary to the previous item (1), a guide groove hole in the inclined direction is opened in the lock plate, and the lock plate is directed to the left and right engagement and release positions via the stepped screws passed through the guide groove hole. And slidably guided and supported (claim 3).

According to the above configuration, when the outer door is closed and the slider lock is locked to the latch of the main body cabinet, the lock plate of the auxiliary lock slides from the released position to the locked position in conjunction with the movement of the slider lock. The outer door is double-locked by directly engaging with the front edge of the outer box of the main body cabinet from the inside. Moreover, the auxiliary lock is hidden behind the outer door and is not visible at all. Therefore, even if the latch that locks the slider lock using an electric saw or the like is cut from the gap between the outer door and the main body cabinet due to a destructive action, an auxiliary lock separate from this latch is used. Since the outer door and the outer box of the main body cabinet are locked, the outer door cannot be opened immediately, thereby ensuring high anti-theft performance.
If the administrator unlocks the door lock mechanism with the key when the door is opened, the slider lock is pushed up and removed from the latch by operating the handle, and at the same time, the auxiliary lock is retracted from the locked position to the released position. Since the latching state is released from the front edge of the cabinet outer box, the outer door can be freely opened.

  Hereinafter, embodiments of the present invention will be described with reference to the illustrated examples.

1 to 4 show an embodiment corresponding to claims 1 and 2 of the present invention. In each figure, 1 is an outer box of the main body cabinet, 2 is an outer door, 3 is a lever handle type lock door lock mechanism mounted on the outer door 2, 3a is a handle, 3b is a cylinder lock, 3c is a rear of the handle 3a Swing cam 4 connected to the end, 4 is a vertically movable slider lock (U channel type) laid inside the outer door 2 linked to the swing cam 3c, 5 is fixed to the reinforcing metal 1a of the outer box 1 The latch 6 protruding forward from the front edge of the outer box 1 is fixed to the rear side edge (door lock side) of the outer door 2 so as to cover the gap between the outer box 1 and the outer door 2 from the side. An anti-theft cover (refer to Patent Document 2), 7 is an auxiliary lock newly installed according to the present invention, and the auxiliary lock 7 is arranged on the side of the swing cam 3c of the door lock mechanism 3 at a different height from the latch 5 described above. is set up.
Here, the lock plate of the auxiliary lock 7 is a deformed sheet metal product (made of steel plate) as shown in FIGS. 3A and 3B, and a tongue-like linkage leg forward from the U-shaped hook portion. The portion 7a protrudes. Further, as shown in FIG. 2, a wide linkage hole 7a into which the linkage leg portion 7a of the auxiliary lock 7 is fitted is opened on the back surface of the slider lock 4, and the position is relatively aligned with the linkage hole 7a. A guide groove hole 6a inclined in an arc shape is formed in the back plate of the outer door 2 and the base portion of the anti-theft cover 6 provided to overlap therewith. It should be noted that the hole width A of the linkage hole 7a shown in the figure corresponds to the left and right movement ranges corresponding to the locking and releasing positions of the auxiliary lock described later.

In order to attach the auxiliary lock 7 to the outer door 2, the linkage leg 7 a is fitted and inserted into the guide groove hole 6 a and the linkage hole 4 a from the back side of the outer door 2, and the tip of the linkage leg 7 a is a door lock mechanism. 3 on the upper edge of the swing cam 3c. The distal end of the linkage leg 7a is bent in an L shape, and in the locked state of the outer door shown in FIG. 1, the bent end of the linkage leg 7a is engaged with a convex portion formed on the upper edge of the swing cam 3c. In addition, the auxiliary lock 7 is held so as not to come out behind.
With the above configuration, in the locked state of the door in which the outer door 2 is closed and the slider lock 4 is locked to the latch 7 of the outer box 1, it protrudes to the back side of the outer door 2 as shown in FIG. The U-shaped auxiliary lock 7 enters the inside of the front edge of the outer box 1 and engages with the front edge wall 1b. At this position, the link leg 7a is connected to the guide groove hole 76a and the link hole 4a of the slider lock 4. It is held in place so that it does not move left and right. Further, in the locked state of the auxiliary lock 7, the tip of the linkage leg 7a of the auxiliary lock 7 is engaged with the swing cam 3c to prevent the lock plate from coming out.

On the other hand, when opening the outer door 2, the key 3d is used to unlock the cylinder lock 3b of the door lock mechanism 31, and the handle 3a is turned counterclockwise as shown in FIGS. 4 (a) and 4 (b). When it is turned to, the swing cam 3c at the rear end pushes up the slider lock 4 in conjunction with this and releases the locked state with the latch 5 (see FIG. 1). When the slider lock 4 moves upward, the linkage leg portion 7a of the auxiliary lock 7 linked to the slider lock 4 slides obliquely upward along the guide slot 6a, and the lock plate is the front edge wall portion of the outer box 1. It escapes from 1b and retreats to the release position (arrow P in FIG. 4 (b)). As a result, the outer door 2 can be freely opened by subsequently pulling the handle 3a forward.
That is, when the outer door 2 is closed and the handle 3 is locked, the door is double-locked by the engagement with the slider lock 4 / the latch 5 and the auxiliary lock 7 / the front edge wall 1b of the outer box 1. It will be. In addition, the auxiliary lock 7 is installed at a different height from the latch 5 and is hidden behind the door on the back side so that its presence cannot be visually recognized from the outside.

Therefore, it is assumed that the latch 5 locked to the slider lock 4 of the outer door 2 is cut with a tool such as an electric saw due to a destructive action aiming at money or goods stored in the vending machine. However, since the space between the outer box 1 and the outer door 2 is locked in the locked state by the auxiliary lock 7, the door cannot be opened immediately, thereby improving the anti-theft property of the vending machine.
Moreover, since the auxiliary lock 7 is engaged and released in conjunction with the operation of the handle-type lock door lock mechanism 3, an auxiliary lock with an independent lock is additionally provided on the outer door as a conventional anti-theft measure. Compared with double locking the outer door using a chain lock, the door lock can be locked and unlocked in one place, and the auxiliary lock 7 is hidden behind the outer door and visible from the outside. Therefore, there is little possibility that the breaking action is directly applied to the auxiliary lock 7.
In the illustrated embodiment, an anti-theft cover 6 (see Patent Document 2) is attached to the outer door 2, and a guide slot 6a is formed in the substrate portion of the anti-theft cover 6 to lock the auxiliary lock 7 in the release position. Although the guide is provided, but the anti-theft cover 6 is not provided, it can be dealt with by opening a guide groove hole of the auxiliary lock on the rear surface of the outer door 2.

Next, the configuration of an application embodiment corresponding to claim 3 of the present invention is shown in FIGS. That is, in the first embodiment, as a means for guiding the auxiliary lock 7 to the locking position / release position, an inclined guide slot 6b is formed on the back surface of the outer door 2, and the guide slot 6b is provided with an auxiliary. The linkage leg 7a of the lock 7 is inserted and guided to move to the locked and released position. In this embodiment, as shown in FIG. 6, the guide slot 7b inclined to the lock plate itself of the auxiliary lock 7 is provided. And a stepped screw 8 fitted in the guide slot 7b is fixed to the back surface of the outer door 2 for guidance. Other structures are the same as those in the first embodiment.
In this configuration, as in the first embodiment, when the slider lock 4 is raised and lowered by operating the handle of the door lock mechanism 3 when the outer door 2 is opened and closed, and the auxiliary lock 7 moves up and down in conjunction with this, the auxiliary lock 7 Is guided by the guide slot 7a / stepped screw 8 and slides to the locking position and the releasing position, and when the outer door 2 is closed, it is locked to the front edge wall portion 1b of the outer box 1 as in FIG. Double lock the door.
