DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fall prevention device for preventing a vending machine from falling forward or backward of the vending machine.

[0002]

2. Description of the Related Art A vending machine is installed by attaching landing members 2 to the four bottom corners of a vending machine main body 1 as shown in FIG. The landing member 2 referred to here is formed integrally with the screw shaft portion 3, the hexagonal portion 4, and the dish-shaped landing portion 5,
The screw shaft 3 is screwed into a female screw welded to the bottom of the vending machine main body 1, and the hexagonal portion 4 of the landing member 2 is rotated with a wrench to adjust the length of the landing member 2. Thus, the level adjustment of the vending machine main body 1 is performed.

Further, in order to prevent the vending machine from falling forward, in JIS B8562 "Standards for installing vending machines", for example, as shown in FIG. It is necessary to attach two ski-shaped iron plates 6.

[0004]

When a ski-shaped iron plate 6 as shown in FIG. 7 is used, when installing the vending machine, the two iron plates are placed at an interval between the legs of the vending machine. C, the vending machine is placed on top of this, and the fixing metal 7 needs to be fixed to the iron plate 6 with bolts 8. FIG. 8 shows a detailed structure of the landing member 2, the fixture 7, and the iron plate 6 when the fixture 7 is attached to the bolt 9 welded to the iron plate 6 with a nut 10.

However, in such a case, it is necessary to perform a large-scale operation of placing the vending machine main body 1 which is a heavy object at an accurate position on the iron plate 6, and the installation workability is poor. Further, when trying to adopt this installation standard for an existing vending machine, it is necessary to lay the iron plate 6 under the vending machine main body 1 by lifting the installed vending machine. However, the workability is extremely poor for existing vending machines.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fall prevention device having good installation workability irrespective of new installation and existing vending machines.

[0007]

According to the present invention, there is provided a fall prevention device comprising: a lever having an upper end pivotally supported by a vending machine main body so that the lower end can rotate in the front-rear direction of the vending machine; And a weight that is attached to the vending machine body and is positioned near the installation surface of the vending machine when the vending machine body is in an upright posture.

[0008]

According to this configuration, when the vending machine main body is tilted forward or backward from the upright posture, the lever is maintained in the vertical posture by the action of the weight attached to the lower end so as to maintain the vertical posture. The lever rotates and the lever comes into contact with the installation surface of the vending machine via the weight, thereby preventing the vending machine from falling down.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS. 1 and 2 show a first embodiment.

As shown in FIGS. 1A and 1B, a lever 12 is rotatably mounted on a side surface 11, 11 of a vending machine main body 1 by a shaft 13. A weight 14 is attached to a lower end of the lever 12. Reference numeral 15 denotes a stopper for restricting the rotation of the lever 12. G represents the center of gravity of the vending machine main body 1.

When the vending machine body 1 is in the upright posture, a gap 15 is formed between the weight 14 and the installation surface C of the vending machine. With this configuration, if an accident occurs in which the vending machine main body 1 tilts forward, the lever 12 pivots in the vertical direction by the action of the weight 14, as shown in FIG. The vending machine body 1 is prevented from further tilting by contacting the installation surface C.

Although FIG. 2 shows the vending machine main body 1 in a state of being greatly inclined, in actuality, by reducing the gap 15, the weight of the vending machine main body 1 is slightly inclined. 14 can be configured to contact the installation surface C.

FIG. 3 shows a second embodiment. In the first embodiment, the lever 12 provided with the weight 14 at the lower end is rotatably pivoted to a position near the front surface A where the customer service surface 16 of the vending machine main body 1 is formed. As shown in FIG. 3, the vending machine main body 1 can be pivotally supported at a position close to the rear surface D, so that the vending machine main body 1 can be prevented from falling over.

FIG. 4 shows a third embodiment. In the third embodiment, the lever 12 with the weight 14 attached to the lower end is pivotally supported at a position close to the front face A of the vending machine main body 1 and is also pivoted to a position near the back face D. The vending machine is pivotally supported so that the vending machine main body 1 can be prevented from falling back and forth.

FIG. 5 shows a fourth embodiment. In the fourth embodiment, a single lever 12 having a weight 14 attached to the lower end is attached to the center of the side surface 11 of the vending machine main body 1, and the vending machine main body 1 falls back and forth. Can be prevented.

The lever 12 with a weight in each of the above embodiments is
Even if it is provided on both sides 11, 11 of the vending machine body 1,
Alternatively, the effect of preventing falling can be expected simply by providing it on one side surface 11.

[0017]

As described above, according to the present invention, a lever whose upper end is pivotally supported by the vending machine main body so that the lower end can rotate in the front-rear direction of the vending machine, and which is attached to the lower end of the lever. When the vending machine main body is in the upright posture, a weight is provided near the installation surface of the vending machine, so that when the vending machine main body is tilted forward or backward from the upright posture, the lever is moved to the lower end. By the action of the attached weight,
Rotate with respect to the vending machine body so as to maintain a vertical posture,
The lever contacts the installation surface of the vending machine via the weight, and can prevent the vending machine from falling down.

Further, since the lever is simply attached to the side of the vending machine main body, the existing vending machine can be mounted without lifting the whole, and the workability is improved as compared with the conventional fall prevention device. Is good.
