BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIGS. The same reference numerals are given to those having the same functions as those of the conventional vending machine.

As shown in FIGS. 1 to 3, a lock frame 15 as a vertically long door-side lock member is supported on the front door 10 so as to be vertically movable inside a rear surface of a door body 16 as a door-side fixing member. Has been done. In a normal state such as when selling a product, the tip of the lock plate 2 protruding toward the front door 10 side from the vending machine body 1 is inserted into the square hole 15a formed in the lock frame 15, and the square hole of the lock frame 15 is formed. The cutout portion 2b of the lock plate 2 is inserted into the lower end portion of the peripheral wall of 15a from above and the claw portion 2a at the tip thereof is engaged to be locked, and the opening operation of the front door 10 is prohibited.

When a staff member opens the front door 10 such as when replenishing merchandise, a predetermined key is inserted into the key cylinder 14 (see FIG. 5) and rotated. Then, in conjunction with this, the lock frame 15 descends and the peripheral wall portion of the square hole 15a is disengaged to a position where it does not engage with the claw portion 2b of the lock plate 2, so that the front door 10 as shown in FIG. Can be opened and closed freely.

As shown in FIGS. 1 to 3, a metal outer cover 17 is intimately welded to a rear end portion of the door body 16 of the front door 10, and further, a back surface of the outer cover 17 is further welded. The inner cover 21 made of metal is closely welded. The outer cover 17 and the inner cover 21 are U-shaped in a plan view, and the outer cover 17, the inner cover 21 and the door body 16 are provided with the lock plate 2 like the lock frame 15. Square holes 17a, 21a, 16a are formed for insertion.

Here, as shown in FIGS. 1 and 2, the outer surface side end portion of the outer cover 17 is extended rearward from the outside of the rear surface of the front door 10 toward the outside of the vending machine body 1, and this extension is performed. The installation portion 17b covers the gap between the front door 10 and the vending machine body 1 from the outside. Further, the outer surface side end portion of the inner cover 21 extends rearward from the back surface of the outer cover 17 toward the inside of the vending machine body 1, and the extension portion 21b also allows the front door 10 and the vending machine body 1 to be extended. The gap between and is covered by the inside. Further, the extended portion 2 of the inner cover 21
A plurality of protrusions 21c projecting further rearward are provided on the 1b at appropriate vertical intervals.

Reference numeral 3 is a case body of the vending machine body 1, and 4 is a case reinforcing member as a mounting member fixed to the inside of the front edge of the case main body 3. The lock plate 2 is fixed.
Then, on the surface of the case reinforcing member 4 facing the front door 10, hole portions 4a are formed at positions corresponding to the protrusions 21c of the inner cover 21, and when the front door 10 is closed, the case reinforcing member 4 is formed. The projection 21c of the inner cover 21 is adapted to be inserted into the hole 4a of No. 4.

According to the above construction, the extended portion 17b of the outer cover 17 not only covers the gap between the front door 10 and the vending machine body 1, but also the extended portion 21b of the inner cover 21. Also, the gap between the front door 10 and the vending machine body 1 is covered. Therefore, in an attempt to steal the front door 10 by prying open the door 10 with something like a bar A, there is a gap between the case body 3 on the vending machine body 1 side and the outer cover 17 on the front door 10 side. Even when the tip of the burl A is forcibly thrust (indicated by the arrow B), the tip of the burl A only comes into contact with the joint between the inner cover 21 and the outer cover 17 or the extended portion 21b of the inner cover 21. Yes, square hole 1 of lock plate 2 and lock frame 15
It does not reach a location such as 5a.

Further, the extended portion 21 of the inner cover 21 is further provided.
Since b is further extended and the projection 21c is projected into the hole 4 of the case reinforcing member 4, a jig such as the burl A reaches the lock plate 2, the square hole 15a of the lock frame 15, or the like. This can be more surely prevented, and the bar A can be
Even if a great deal of force is applied by the inner cover 2
It is also possible to prevent the protruding portion 21c of No. 1 from coming into contact with the case reinforcing member 4 and largely bending the extended portion 21b of the inner cover 21 inward.

In this way, even if the tip of the burl A is forcibly thrust into the gap between the vending machine body 1 and the front door 10, the lock plate 2, the square hole 15a of the lock frame 15, etc. Since it is surely prevented that the place is deformed or destroyed, the front door 10 is never opened and the theft can be prevented.

In the above embodiment, the case where the inner cover 21 and the outer cover 17 are extended vertically also covers the entire gap between the vending machine body 1 and the front door 10. However, the invention is not limited to this, and at least the portion of the lock plate 2 or the lock frame 15 facing the gap between the front door 10 and the vending machine body 1 may be covered with the inner cover 21 and the outer cover 17. Good. In addition, in the above-described embodiment, not only the inner cover 21 but also the outer cover 17 is provided on the back surface of the front door 10 so that the gap between the front door 10 and the vending machine body 1 is double. Although it has been described that the cover member can be reliably covered with the lock plate 2 and the lock frame 15 to prevent deformation and destruction of the vending machine body side locking member and the door side locking member, the outer cover 17 may be omitted in some cases. It is also possible. That is, although the case where the inner cover 21 is fixed to the outer cover 17 has been described in the above embodiment,
The inner cover 21 and the outer cover 17 may be fixed to a member fixed to the door side. Further, it goes without saying that the engaging structure of the vending machine main body side locking member and the door side locking member is not limited to the above embodiment.

[0024]

As described above, according to the present invention, the inner cover that extends rearward from the back surface of the door toward the inside of the vending machine main body is fixed to the member fixed to the back surface of the door. By covering the vending machine main body side locking member and the part of the door side locking member facing the gap between the door and the vending machine main body, a jig such as a burl is provided in the gap between the door and the vending machine main body. Even if the tool is pushed in, such jigs are prevented from entering with the inner cover, so that the jigs such as crowbars will not reach the vending machine body side lock member and door side lock member, and theft should be prevented. You can

Further, a plurality of protrusions projecting further rearward are provided on the rearwardly extending portion of the inner cover, and the protrusions of the inner cover are inserted into the holes formed in the mounting member, whereby the vending machine It is possible to more reliably prevent a jig such as a burl from reaching the main body side lock member or the door side lock member, and even when a great amount of force is applied to the extended part of the inner cover by the burl, It is also possible to prevent the extended portion of the inner cover from being largely bent inward.
