Description

The present invention is a display dummy attached to a display part of a vending machine for unattended sales of coffee, juice, beer, tea or other containers, or cigarettes, dry batteries, etc. This relates to the mounting structure.

For example, in a vending machine for various beverages and other products contained in containers such as plastic bottles, a stage is provided on the front display part, and a display dummy is installed on this stage. A display dummy having the same shape as the product to be formed and having a fitting portion formed in the lower portion is formed, and the fitting portion is fitted into a fitting hole formed in the stage.

In such cases, since the cost is high, a half display dummy called half is used in recent years. When such a display dummy is a half, the vibration and wind pressure when the door is opened and closed is used. There is a risk that the dummy installed on the stage may be tilted, displaced or detached.
Therefore, in order to deal with these problems, a main body that vertically divides a member that has the shape of a container that wraps the products to be sold and has a lid, and a vending machine that is connected to the lower part of the main body are displayed. A substantially C-shaped insertion portion in a cross-sectional view that can be locked to a substantially circular opening provided in the pedestal portion of the portion, and the insertion portion protrudes outward from the outer peripheral surface thereof, and A locking portion and bottom surface that form a ridge that can be locked to the opening are formed, and the left and right side surfaces of the main body are urged inward to be deformed to be attached to and detached from the display portion of the vending machine. Proposed in advance is a viewing body configured to be free and further formed with extending portions extending rearward on the left and right sides thereof.

However, according to the previous proposal, since the insertion portion is formed by a substantially C-shaped portion in a cross-sectional view and an extension portion extending rearward on the left and right sides thereof, the insertion portion is formed of a circular opening. There is a slight difference in the thickness of the sheet metal on the stage where the dummy is fitted without being in close contact with the peripheral part, and it is said that the holding force is also reduced when the thickness is reduced due to cost reduction of the sheet metal. There was a fatal problem.
In particular, in a case where a substantially C-shaped portion in cross-sectional view and an extension portion extending rearward on both right and left sides thereof are formed by vacuum forming, the synthetic resin sheet is stretched like a deep drawing, so that the thickness of the insertion portion is increased. The thickness is extremely thin and the strength is low, so that sufficient holding force cannot be obtained, and the peripheral edge portion of the circular opening is damaged or torn at the time of mounting, which causes problems in quality and durability.

T) Display chambers 5 for displaying display bottles 4 of so-called bottle (so-called PET bottles) type are provided in the upper and lower stages, and the front door 2 is a push for selecting products related to the dummy 3 and 4 Buttons 6, 6... Are arranged.
In addition, a product takeout port 7 is provided on the lower side of the front door 2, and in addition to this, a money insertion port, a change port 9 and a money return operation lever 10 indicated by reference numeral 8 are provided. .

A stage 11 serving as a mounting surface for the dummy 3 and 4 is provided inside the display chamber 5.
This stage 11 has a metal band plate that is formed in a “U” shape downward in a side view, and is fitted to a lower portion of a dummy 3 and 4 described later at a position where a dummy 3 and 4 on the upper surface portion is attached. A fitting hole 13 for fitting the joint portion 12 is formed.
As shown in FIG. 1, the fitting hole 13 has a light transmitting hole for irradiating the light of the fluorescent lamp 14 installed on the inner side of the stage 11 from the inner side of the display dummies 3 and 4 to lift the product. Also, it is based on a circle formed with a diameter smaller than the diameter of the dummy 3 or 4, and each of the symmetric positions of the peripheral portion has a large and small semicircular recess as shown by a two-dot chain line in FIG. 2. In many cases, it is formed by providing the alignment portions 15 and 16 for alignment.

On the other hand, the display dummies 3 and 4 installed on the stage 11 are formed as shown in FIGS.
That is, the display dummies 3 and 4 are printed on one side of a polycarbonate transparent sheet having excellent heat resistance and weather resistance by the same printing as the product, and vacuum-molded so that the printed surface is inward. The lower part is formed in half with a fitting part that fits into the fitting hole of the stage, and the fitting part 12 is formed integrally with the vacuum forming.

The outer peripheral surface (bottom surface) 19a of the circular groove portion 19 is composed of a plurality of arcs a, b, and c, as will be described later, and is formed larger than the radius r1 of the fitting hole 13.
Here, the gap 22 in which the groove portion 19 is formed is slightly wider than the thickness of the fitting hole 13 of the stage 11 because the groove portion 19 including the gap 22 is formed by vacuum forming the synthetic resin sheet. The reason is that the thickness of the portion where the groove portion 19 including the gap 22 is formed is prevented from becoming too thin by increasing the area of the extended portion as much as possible.

Incidentally, as described above, it is advantageous that the gap 22 is wide. However, if the gap 22 is widened, it becomes easy to cause rattling in the vertical direction, and the gap between the dummy body 17 and the upper surface of the stage when the display dummy 3 or 4 is installed. It becomes unsightly.
Therefore, the gap 22 is widened to such an extent that it does not become unsightly, and rattling in the vertical direction is prevented by a clamping protrusion 23 described later.

The fitting protrusions 21 are provided at two positions on the front end portion of the outer periphery of the bottom surface 24 of the fitting portion 12 and the left and right portions, respectively. Protrusions are formed.
The triangular clamping protrusion 23 clamps the peripheral edge portion 12 of the fitting hole 13 of the stage 11 having a thickness of about 1 mm, for example, to prevent vertical rattling.
Although the triangular clamping protrusions 23 are three in the drawing, the number may be one or two, and it goes without saying that the number may be four or more.
In addition, in the case where the engagement hole 13 is provided with the alignment engaged portions 15 and 16 formed of large and small semicircular depressions, the fitting portion 12 corresponding to this is fitted to the fitting portion 12 at a regular position. A circular alignment engagement portion 25 is formed (the alignment engagement portion corresponding to the alignment engagement portion 16 is not shown).

As shown in FIG. 6, the semicircular shape of the groove portion 19 has a plurality of (three) radiuses r2 smaller than the radius r1 of the substantially circular fitting hole 13, each having different centers O, P, and Q. The arcs a, b, and c are made continuous to form a semicircular shape, and the rear end portion 19 b of the semicircular groove portion 19 is positioned outside the maximum diameter (diameter) portion of the fitting hole 13 in a free state. It is formed to do.
As described above, when the groove portion 19 has a radius r2 smaller than the radius r1 of the fitting hole 13 and a plurality of arcs a, b, and c formed by different centers O, P, and Q are continuously formed into a semicircular shape. As shown in a partially enlarged view in FIG. 6, a recessed portion 26 is formed at the end of adjacent arcs a, b, and c, and this recessed portion 26 reinforces the groove portion 19.

Next, the case where the display dummy 3 and 4 configured as described above are attached to the stage 11 will be described.
As shown in FIG. 7, the both ends of the fitting portion 12 of the display dummy 3, 4 are sandwiched between fingers, and the peripheral surface portion of the fitting hole 13 is formed on the periphery of the fitting portion 12. And inserted into the groove portion 19 between the clamping projection 23 formed on the bottom portion 20 of the dummy main body 17.
Next, the peripheral portion of the fitting hole 13 is hidden with the fitting protrusion 21 formed in the vicinity of both ends of the peripheral edge of the fitting portion 12 by elastically deforming the vicinity of the fitting portion 12 held by the hand. Thereafter, the finger is moved away from the fitting portion 12 of the display dummy 3 and 4, and the portion is elastically restored.

When the fitting portion 12 is elastically restored, the periphery of the fitting hole 13 is sandwiched between the fitting projection 21 and the triangular projection 23 formed on the bottom portion 20 of the dummy body 17 in a side view. In addition, as shown in FIG. 8, the rear end portion 19 b of the groove portion 19 of the fitting portion 12 fitted in the fitting hole 13 is formed on the rear side portion that gradually becomes smaller in diameter than the diameter portion of the fitting hole 13. Abut.
By the elastic restoring force of the rear end 19b of the groove portion 19 (expansion force) a force rearward end 19b of the groove portion 19 to shift to the large diameter portion (diameter portion) of the fitting hole 13, i.e., fitted Since a force for pushing the joint portion 12 forward is generated, substantially the entire outer periphery of the semicircular groove portion 19 abuts on the fitting hole 13 and the display dummy 3 and 4 are securely held in the fitting hole 13. The display dummy 3 and 4 are attached to the stage 11.

When the position of the display dummy 3 or 4 attached to the stage 11 is deviated from the normal position, the display dummy 3 or 4 is simply rotated while attached to the stage 11. The dummys 3 and 4 can be rotated, and when the normal dummy position is set, the mounting operation is completed.
Further, in the case where the engaging hooks 15 and 16 are formed in the fitting holes 13 and the engaging hooks 25 are formed and rubbed on the fitting part 12, these alignment hooked parts 15 and 16 are formed. Then, the display dummy 3 and 4 can be easily fixed at the normal position of the stage 11 simply by engaging with the alignment engagement portion 25.

In the above-described embodiment, the semicircular shape of the groove portion 19 has a radius r2 smaller than the radius r1 of the substantially circular fitting hole 13 and a plurality (three) of different centers O · P · Q. The arcs a, b, and c are formed in a continuous semicircular shape, and a recess 26 that reinforces the groove portion 19 is formed at the ends of the adjacent arcs a, b, b, and c. As shown, for example, of these three arcs a, b, and c, the radius r3 of the left and right arcs a and c is made larger than the radius r1 of the fitting hole 13, and the centers Q and O of the left and right arcs a and c are When the arcs a, b, and c are switched at a portion passing through the center P of the intermediate arc b, the semicircular shape in which the rear end portion 19 b is gently positioned outside the maximum diameter (diameter) portion of the fitting hole 13.
