The level of the vending machine 1 is adjusted by adjusting the projecting length of the screw shaft portion 4.

[0003] In order to prevent the vending machine 1 from falling forward, JIS B8562 "Standards for installing vending machines", for example, as shown in FIG. It requires the use of two ski-shaped iron plates 8 extending forward. In order to attach the iron plate 8, at the time of installation of the vending machine 1, two iron plates 8 are arranged on the installation surface 3 with an interval between the landing members 2, and after the vending machine 1 is placed on the iron plate 8, the fixing bracket is mounted. 9 bolts
Fix to the iron plate 8 with 10. Further, as shown in FIG. 9, there is a structure in which a fixing metal 9 is fixed to a bolt 11 welded to an iron plate 8 with a nut 12.

[0004]

However, when the iron plate 8 as described above is used, it is necessary to place the heavy-weight vending machine 1 at an accurate position on the iron plate 8, and it is necessary to fix the vending machine 1. Since the metal fitting 9 needs to be attached to the iron plate 8 with the bolt 10 or the nut 12, there is a problem that the workability of the installation is not good.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a fall prevention plate having good installation workability.

[0006]

In order to achieve the above object, a fall prevention plate according to the present invention is provided with a landing member provided with a landing portion at a lower end of a screw shaft portion screwed to four corners at the bottom of a vending machine. A fall prevention plate that engages with two front and rear holes, and two long holes for guiding the screw shafts of the front and rear landing members in the front and rear direction are provided at both front and rear ends, and at least the front end side long holes of these two long holes are provided. The lower surface is provided with a concave portion for accommodating the landing portion of the front landing member, and a rear end of the long hole is provided with a through hole through which the landing portion of the front landing member can be inserted.

[0007]

[Operation] To attach the fall prevention plate having the above structure to a vending machine, first lift the vending machine and insert the screw shaft portion of the rear landing member through the slot on the rear end side. After the landing portion is inserted into the through hole, the fall prevention plate is shifted backward to accommodate the landing portion in the concave portion, and then the vending machine is lowered.
When the vending machine to which the fall prevention plate is attached in this way is tilted forward, the rear landing member engages with the rear end side long hole by contacting the lower surface of the long hole. Therefore, the fall prevention plate is lifted by the rear landing member on the rear end side and tilts forward and downward with the front end as a fulcrum, thereby preventing the tilting movement of the vending machine.

And a seat plate 25 having a groove-shaped cross-section is fixed to the lower surfaces of both long holes 23.

In order to attach the fall prevention plate having the above structure to the vending machine 1, first, the vending machine 1 is lifted and the hexagonal portion 5 and the landing portion 6 of the front and rear landing members 2 are transmitted through the front and rear of the prevention plate body 21. Then, the prevention plate body 21 is shifted rearward to accommodate the front and rear hexagonal portions 5 and the landing portions 6 in the recesses 22, and the front and rear screw shaft portions 4 are inserted into the front and rear long holes 23. Then, the vending machine 1 is lowered, and the front and rear landing portions 6 are seated on the front and rear seat plates 25 (see FIG. 1). The distance between the front and rear landing members 2 is shorter (longer) than the distance between the front and rear through holes 24.
First, after inserting the rear (front) hexagonal portion 5 and the landing portion 6 into the rear (front) through hole 24 to shift the prevention plate body 21 backward, the front (rear) hexagon Part 5 and landing part 6 are inserted into the front side (rear side) through-hole 24, and furthermore, the prevention plate body 21 is shifted rearward to accommodate the front and rear hexagonal part 5 and landing part 6 in the recess 22, and then the automatic The vending machine 1 is lowered to obtain the state shown in FIG. As described above, the attachment of the fall prevention plate is performed by inserting the front and rear hexagonal portions 5 and the landing portion 6 into the front and rear through holes 24, and inserting the prevention plate body
21 is shifted backward, and the hexagonal part 5 and the landing part 6 on the front and rear are
Since it only needs to be accommodated in the 22, accuracy is not required and it is extremely simple. Therefore, the workability of the installation of the vending machine 1 is also good.
