Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a support foot holding device for a vending machine.

[0002]

2. Description of the Related Art As a conventional supporting foot holding device in a vending machine for soft drinks, cigarettes and other products, for example, FIG.
And those shown in FIG.

In this supporting leg pressing device, between the supporting leg 102 of the vending machine 101 and the anchor bolt 103 planted on the installation surface S of the vending machine 101, a connecting plate 104 is inserted through the supporting leg 102 and the anchor bolt 103. The connection plate 104 is pressed toward the installation surface S by the nut 105 screwed to the anchor bolt 103, and the flange-shaped bottom piece 106 of the support leg 102 is pressed against the installation surface S by the connection plate 104.

According to this device, the vending machine can be prevented from skidding (movement on the installation surface S) and the vending machine as a whole overturning due to vibration of a passing vehicle in the vicinity or an earthquake. It is being carried out in various places because it enhances the quality.

However, in the conventional device as described above, the supporting leg 102, the connecting plate 104 and the anchor bolt 10 are used.
Since all 3 are made of metal such as iron and are rigidly connected to each other, most of the vibration applied to the vending machine body 101 due to a passing vehicle or an earthquake is transmitted to the anchor bolt 103. become.

Therefore, during long-term use or occurrence of a strong earthquake, a crack is formed around the locking hole 108 of the installation base into which the sheath pipe 107 of the anchor bolt 103 is fitted, and the anchor bolt 103 is fixed in a fixed state. If it becomes loose or in extreme cases, the anchor bolt will come off.

The loosening of the anchor bolts 103 means that the bolts 103 can be easily pulled out, and the device does not exert the pressing action of the supporting leg at all.

[0008]

SUMMARY OF THE INVENTION The supporting leg pressing device for a vending machine according to the present invention has been proposed to solve the above-mentioned problems. That is, it was proposed for the purpose of improving durability and being able to endure a relatively large earthquake.

[0009]

In order to achieve the above-mentioned object, a supporting leg pressing device for a vending machine according to the present invention is a supporting leg of the vending machine, wherein the supporting leg of the vending machine has a length adjustable screw rod, a tool engaging portion and a flange-shaped bottom piece. The anchor bolts should be planted on the installation surface of the vending machine; the anchor bolts should be connected to the supporting legs with a connecting plate; the connecting plate should have peripheral hem pieces and anchor bolts. It has a long hole for inserting a hole and a supporting leg insertion hole communicating with the outside by a notch; when the anchor bolt and the supporting leg are inserted through the long hole and the supporting leg inserting hole of the connecting plate, respectively, the upper surface of the supporting leg bottom piece and the connecting plate. A rubber-like elastic body between it and the back surface of; the rubber-like elastic body has a support leg through hole that communicates with the outside by a notch; and the connecting plate is a nut screwed to the anchor bolt. Vending machine Is pressed toward the surface, with the proviso that suppress bottom piece support leg via a rubber-like elastic body.

[0010]

1 and 2, when the vending machine 1 vibrates (displaces) upward in FIG. 1 together with the support leg 2 when the vending machine 1 vibrates (displaces), the upper surface of the flange-shaped bottom piece 23 of the support leg 2 and the anchor. The rubber-like elastic body 6 held between the bolt 3 and the back surface of the connecting plate 5 which is rigidly pressed by the nut 4 is elastically compressed and deformed, so that a part of the vibration is absorbed.

Therefore, the upward vibration of the vending machine 1, that is, the support leg 2 is damped by the rubber-like elastic body 6, and the anchor base 3 is locked on the installation base during long-term use or occurrence of a strong earthquake. The loosening of the holes 9 is suppressed.

Considering this buffer action in terms of energy, it is as follows. That is, for example, when earthquake energy is applied to the vending machine due to an earthquake, the seismic energy is eventually absorbed somewhere in the vending machine.

In the vending machine, the supporting foot pressing device mainly absorbs the seismic energy. Then, the seismic energy absorbed by the supporting foot pressing device is the product of the load applied to the supporting foot pressing device and the elastic deformation amount thereof.

In the conventional supporting leg holder of the vending machine, a load acts so that the bottom piece 106 of the supporting leg lifts the free end (right end) of the connecting plate 104 upward in FIG.

At this time, since the amount of elastic deformation of the connecting plate 104 is small, a large upward load is applied to the free end of the connecting plate 104, and this load is expanded by the pulling action to pull out the anchor bolt 103 from the installation surface S. Act on.

On the other hand, in the support foot pressing device of the vending machine according to the present invention, as apparent from FIG. 1, the load acting upward on the free end of the connecting plate 5 is connected by the elastic deformation amount of the rubber-like elastic body 6. Since it is larger than that of the plate 5, it is significantly reduced as compared with the conventional one.

Therefore, although the vibration amplitude of the vending machine is increased, the load applied to the anchor bolt 3 is also significantly reduced.

[0018]

EXAMPLES Hereinafter, based on the examples shown in FIGS. 1 and 2,
The present invention will be described. Reference numeral 1 is an automatic vending machine, and 2 is an arbitrary number (usually 4) of supporting legs provided in a lower corner portion or the like.

Each supporting leg 2 is attached to the lower part of the vending machine 1 by screwing so that the length (height) can be adjusted, and a screw rod 21 for detachably engaging a tool such as a spanner. And a flange-shaped bottom piece 23 fixed to the lower end of the screw rod 21 via the tool engaging portion 22.

Each supporting leg 2 on the installation surface S of the vending machine 1
A locking hole 9 is provided in the vicinity of, and the anchor bolt 3 is planted in the locking hole 9 through the sheath tube 30.

A connecting plate 5 for connecting the anchor bolt 3 and the supporting leg 2 which has a rectangular planar shape or another arbitrary shape.
Is usually manufactured by bending a single iron plate, a steel plate or other metal plate, and a hem piece 51 that serves as a spacer is hung down on the periphery thereof.

Further, the flat plate portion of the connecting plate 5 is provided with long holes 52 through which the anchor bolts 3 are inserted and support leg insertion holes 53 which are communicated with the outside by notches 54 at appropriate intervals.

When assembling the connecting plate 5, when the anchor bolt 3 and the supporting leg 2 are inserted into the long hole 52 and the supporting leg insertion hole 53 of the connecting plate 5, respectively, the upper surface of the supporting leg bottom piece 23 and the back surface of the connecting plate 5 are connected. A rubber elastic body 6 having a supporting leg through hole 61 communicated with the outside by a notch 62 and having a planar shape of C-shape or other arbitrary shape is interposed therebetween.

The notch 62 of the rubber-like elastic body 6 forms a passage for fitting the support leg 2 into the support leg through hole 61 from the lateral direction.

If the rubber-like elastic body 6 is integrally fixed beforehand to the back surface of the connecting plate 5 by baking adhesion or the like, the work can be facilitated at the time of assembling the support foot pressing device at the site, and the parts management is also possible. Is also preferable.

After the connecting plate 5 and the rubber-like elastic body 6 are arranged as described above, the nut 4 screwed onto the anchor bolt 3 is used.
Thus, the connecting plate 5 is pressed toward the installation surface S of the vending machine 1, and the upper surface of the support leg bottom piece 23 is restrained on the back surface of the connecting plate 5 via the rubber-like elastic body 6.

The height position of the connecting plate 5 at this time is determined by the connecting plate 5.
It is regulated by the hem piece 51 of abutting against the installation surface S.

Although the nut 4 is shown as a single nut in the illustrated example, this nut may be a double nut. It goes without saying that a washer or the like for preventing loosening may be interposed between the nut 4 and the connecting plate 5.

In the assembled state shown in FIGS. 1 and 2,
The rubber-like elastic body 6 is naturally mounted in a state of being slightly compressed in its thickness direction.

In other words, the depth of the connecting plate 5 (hem piece 51
Height) is smaller than the sum of the thickness of the support leg bottom piece 23 and the thickness of the rubber-like elastic body 6 in a free state (non-compressed state).

It should be noted that the optimum mounting state varies depending on the size and the value of the elastic coefficient of the rubber-like elastic body 6, but when the elastic coefficient of the rubber-like elastic body 6 is large, as shown in FIG. As shown, when the hem piece 51 of the connecting plate 5 is brought into full contact with the installation surface S, the spring coefficient of the rubber-like elastic body 6 may be slightly increased.

In such a case, the hem piece 51 at the free end of the connecting plate 5 should be slightly lifted from the installation surface S, and the connecting plate 5 should be placed on the leg piece 23 of the supporting leg in an inclined state. .

In this case, since the force applied to the nut 4 is not so large as the elastic force of the rubber-like elastic body 6, the nut may loosen due to long-term use.

Therefore, in this case, a double nut is used,
It is advisable to prevent loosening of the nuts by tightening the nuts together.

[0035]

As described above, according to the foot support device of the vending machine of the present invention, even if a concentrated vibration occurs due to repeated vibrations of a passing vehicle or a strong earthquake during normal operation, one of the total vibrations is reduced. Since the upward vibration (component force) of the part, that is, the vending machine and the supporting leg is buffered by the compressive deformation of the rubber-like elastic body, the durability and the It has the effect of significantly improving the strength.
