Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door lock device for locking an outer door of a vending machine in a closed state, and more particularly, to a mounting structure of a lock plate. 2. Description of the Related Art FIG. 4 is a perspective view of a vending machine with a front door opened. In FIG. 4, a main body 1 of a vending machine having an open front has an outer box 2 and an inner box 3, and a product (a canned beverage in the illustrated case) is accommodated in the inner box 3 having a heat insulating structure. The front opening of the main body 1 is closed by an inner door 4 having a heat insulating structure and an outer door 5 on the outside thereof, and the side-opening doors 4 and 5 are hinged on the left side of the figure so as to be freely opened and closed. I have.
Lock plate 6 is attached to the inside of the right side wall in the figure of main body outer box 2 so as to protrude forward and downward at two places in the case shown in the figure, and this lock plate 6 is slit when outer door 5 is closed. 7 and enters the outer door 5 and engages with a latch (not shown) to lock the outer door 5 in a closed state. FIG. 5 is an exploded perspective view of a lock plate mounting portion of the vending machine shown in FIG. 4, and FIG. 6 is a cross sectional view thereof. In FIG. 5, a pair of upper and lower arms 6a are bent at right angles to a lock plate 6 in which an engaging groove 8 into which a latch on the side of the outer door 5 is fitted is cut out from above at a front portion. Two mounting holes 10 for passing the mounting screws 9 are provided near the rear. On the other hand, on the inside of the side wall of the outer box 2, a mounting plate 11, which is also a reinforcing plate of the outer box 2, is fixed by welding. A pair of upper and lower rectangular holding holes 12 are provided, and two screw holes 13 are provided corresponding to the mounting holes 10. The lock plate 6 is positioned by inserting the arm portion 6a into the holding hole 12 with a small gap therebetween, and the mounting plate 1
The screw is tightened by the mounting screw 9 screwed into the screw hole 13 through the hole 0, and is fixed to the mounting metal 11 as shown in FIG. In the above vending machine, in order to illegally take out a product, a bar material such as a bur is inserted into a gap between the outer box 2 and the outer door 5 as shown in FIG. 14 may be inserted to attempt to pry out the outer door 5. In this case, when the conventional lock plate 6 receives a force in a direction perpendicular to the plate thickness (the direction of the arrow in FIG. 6), the force is enlarged by leverage to directly act on the mounting screw 9 and its head 9a. However, there was a problem that it broke and flew. Therefore, an object of the present invention is to improve the mounting strength of a lock plate against an external force. In order to solve the above-mentioned problems, the present invention is to integrally form a hook piece projecting forward on an arm portion of a lock plate inserted into a holding hole of a lock plate mounting metal,
The hook piece is to be engaged with the back side of the mounting metal with the arm inserted into the holding hole. By taking such a measure, when an external force is applied to the lock plate in a direction perpendicular to the thickness of the lock plate, the force is received by the hook piece engaging with the lock plate mounting metal, and thus acts on the mounting screw. The mounting screws are not damaged. FIG. 1 is an exploded perspective view of a lock plate mounting portion showing an embodiment of the present invention, FIG. 2 is a front view of a vending machine, and FIG. 3 is a line III-III in FIG. FIG. 3 is a partially enlarged cross-sectional view along the line. Note that the same reference numerals are used for the portions corresponding to the conventional example. In FIG. 2, the outer door 5 of the vending machine
On the front surface of the camera, an illumination plate 15, a deposit panel 16, a product outlet 17 and the like are arranged. The outer door 5 hinged on the left side of FIG. 2 is locked in a closed state by two upper and lower lock plates 6 on the right side, and is unlocked and opened by the turning operation of the handle 18. FIG. 1 shows a lock plate 6 according to the present invention.
The hook 6b projecting forward (to the front of the vending machine) is integrally formed with the arm 6a inserted into the holding hole 12 of the lock plate mounting metal 11. Other configurations are the same as the conventional example. The lock plate 6 is tilted so that the tip side (the right side in FIG. 1) approaches the mounting metal 11, the hook piece 6 b is first passed through the holding hole 12, then the arm 6 a is inserted, and then attached with the mounting screw 9. Tighten to gold 11. Thereby, as shown in FIG. 3, the hook piece 6b is engaged with the back side of the mounting metal 11. According to such a configuration, in FIG. 3, a bar 14 such as a bar is inserted between the outer box 2 and the outer door 5, and the bar 14 is inserted into the lock plate 6 in a direction perpendicular to the plate thickness (arrow). Direction), the force is received by the hook pieces 6b engaging with the mounting metal 11, so that the head is not damaged due to excessive force applied to the mounting screw 9. Here, the configuration and operation of the entire door lock device will be briefly described with reference to FIG. The lock plate 6 is engaged with the latch 19 on the outer door 5 side to lock the outer door 5 in a closed state. The latch 19 having a U-shaped cross section is a long member extending vertically over two lock plates 6 at the top and bottom, and a pin 20 for passing the right and left legs is formed by a vertical direction (not shown) of a guide plate 21 having a U-shaped cross section. And is guided in a vertically movable manner. A square hole 22 is formed in front of the latch 19 in accordance with the lock plate 6, and the upper edge of the square hole 22 falls into the engaging groove 8 (FIG. 1) of the lock plate 6 inserted through the square hole 22. An engagement between 6 and latch 19 is formed. On the other hand, a cam 23 is fixed to the rear end of an operation shaft (not shown) to which the handle 18 is attached to the front end, so that the cam 23 can be rotated integrally with the handle 18. The cam 23 is provided with a square hole 24 on the side of the latch 19.
, And the latch 19 moves up and down in conjunction with the rotation of the cam 23. Then, when the handle 18 is rotated counterclockwise in FIG. 3 in the closed state of the outer door 5 in FIGS. 2 and 3, the latch 19 is lifted by the cam 23 and escapes from the engagement groove of the lock plate 6. . As a result, the lock plate 6 is disengaged from the latch 19, and the outer door 5 can be opened. When the opened outer door 5 is closed, the latch 19 is pressed against the lock plate 6 and its front end slope (FIG. 1).
), And then fall into the engaging groove 8 to re-engage. Note that in FIG.
A burglarproof plate 25 is attached to cover the gap between, and prevents insertion of a crowbar or the like. The handle 18 is locked by a key operation on the key lock 26. As described above, according to the present invention, the lock plate has a simple structure in which the hook piece integrally formed on the arm of the lock plate inserted into the mount is engaged with the mount. The mounting screws can be protected from external forces acting in the thickness direction, and the security against fraud can be increased.
