Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a product display stand used for displaying various products, and more specifically to a product display stand with foldable legs. be.

[Conventional technology and its problems]

Product display stands generally have legs with casters fixed to the back of a base plate for placing and displaying products.
Many of them are moved to display and sell products, but if the legs are fixed when not in use, it is extremely inconvenient to store and transport.

For this reason, foldable legs such as those described in Japanese Utility Model Publication No. 39-30044 are also used for display stands and are widely used.

However, the structure of the legs described in the above-mentioned publication fixes the bases of the pair of left and right support pieces to the substrate, and pivots the upper ends of the legs in the vicinity of the bases in a state that is externally fitted. A tube is provided between the lower parts of the support pieces, and a hook piece with a spherical hook at the tip is elastically supported by the tube, and when the leg is raised, each hook hole formed opposite to the leg itself is inserted into the tube. The spherical engaging portions of the engaging pieces are engaged with each other.

Therefore, when folding the legs, it is necessary to simultaneously release the engagement between the left and right spherical engagement parts and the engagement holes, and the structure itself is extremely complex, requiring a large number of parts for folding. Since the supporting pieces that pivotally attach the legs are not strong, they tend to wobble due to repeated folding operations, and the lifespan of the legs is extremely short, especially when placing heavy items. It was hot.

In view of the current situation, this invention aims to provide a product display stand whose legs can be folded with a single touch and whose legs can be folded with an extremely small number of parts.

[Means for solving problems]

In order to achieve the above object, the product display stand of this invention is a display stand in which the legs are foldably pivoted via the leg attachment parts on the back side of the placing stand for placing the products. is constituted by a square cylindrical member, and constitutes a leg portion having an engaging member having a U-shaped cross section that engages with the peripheral wall of the leg attachment portion fixed at right angles to the base end thereof, and the leg attachment portion and the engaging member of the leg are pivotally supported by a pivot pin on a side surface near one end, and a leaf spring having a substantially chevron-shaped cross section with a pin protruding from the top is provided near the other end of the leg attachment part,
The pin of this leaf spring is always projected from the side surface of the leg attachment part, and a through hole that engages with the pin is provided on the side surface near the other end of the engaging member, and when the leg part is in an upright state, the leaf spring is inserted into the through hole. The pin is engaged, and by pressing the pin and releasing the engagement between the pin and the through hole, the leg portion is folded from the pivot portion along the back surface of the mounting table.

[Effect]

In the product display stand of this invention, a leg attachment part 2 made of a square cylindrical member and an engaging member 4 provided orthogonally to the base end of the leg part 3 are pivotally supported by a pivot pin 6, and the leg attachment part 2 is made of a square cylindrical member. A pin 7 of a leaf spring 8 provided inside the leg attachment part 2 is always projected from the side surface of the leg attachment part 2, and this pin 7 is connected to the engagement member 4.
By fitting the legs 3 into the through holes 9 formed in the openings 9, the legs 3 maintain the normal opened state and securely hold the mounting table.When folding the legs, the head of the pin 7 Push to release the fitting between the through hole 9 of the engaging member 4 and the pin 7, fold the leg part 3 by rotating it approximately 90 degrees inward about the pivot pin 6, and by the reverse operation. It can be put into normal use condition.

〔Example〕

An embodiment of the product display stand of this invention will be described below with reference to the accompanying drawings.

FIG. 1 is a side view showing an example of a product display stand of this invention, with reference numeral 1 indicating a product placement table and 2 indicating a leg attachment portion provided on the back side of the placement table 1.

The leg attachment portion 2 is composed of a square cylindrical member, and one side wall of this cylindrical member is fixed along the back surface of the mounting table 1.

3 is a leg, 4 is an engagement member fixed to the upper end of the leg 3, and as shown in FIGS. It has a U-shaped cross section that covers the surrounding wall.

In addition, 5 in the figure is a caster.

The engagement member 4 fixed to the base end of the leg 3 is
It is attached perpendicular to the leg 3 and when the engaging member 4 is maintained horizontally,
The legs 3 are configured to be vertical.

The engagement member 4 is pivotally supported by a pivot pin 6 at one end of the leg attachment portion 2, and pivots around the pivot pin 6 from a state in which the engagement member 4 covers the leg attachment portion 2 to a state close to a right angle. It is rotatable.

Further, at the other end of the leg attachment part 2, as is particularly clear in FIG. The pin 7 of 8 is always projected from the side surface of the leg attachment part 2 by the biasing force of the leaf spring 8.

On the other hand, a through hole 9 that engages with the pin 7 is formed on the side surface of the engaging member 4 attached to the base end of the leg 3 that faces the pin 7 .

The leg mounting part 2, which has a leaf spring 8 having such a pin 7 therein, and the leg part 3, to which the engaging member 4 is fixed, have pivot pins 6 at the four corners of the back surface of the mounting table 1, respectively, which are connected to the pin 7 of the leaf spring 8. It is also placed on the inside.

[Effect of idea]

The product display stand of this invention is based on a leg attachment part made of a square cylindrical member, and an engaging member with a U-shaped cross section that comes into contact with the peripheral wall of the leg attachment part is arranged orthogonally at the base end of the leg part. Since it is fixed in place, the engagement member provided on the leg attachment part and the base end of the leg part is securely engaged, and since the engagement area of both is large, the entire leg is extremely sturdy. , which does not cause looseness during use.

In particular, since the leg attachment part is a square cylindrical member,
The legs do not wobble in the horizontal direction, and the products can be displayed stably even when heavy products are placed on the mounting table.

In addition, a leaf spring with a nearly chevron-shaped cross section and a pin at the top is installed in the leg mounting part, and the pin of the leaf spring is always projected from the side of the leg mounting part by the biasing force of the leaf spring, and is engaged with this pin. Since a matching through hole is provided on the side surface of the engaging member, the engagement between the pin and the through hole of the engaging member can be released by simply pressing the top of the pin toward the leg attachment part, especially when folding the leg. Since it is a one-touch method, it has the practical advantage of being extremely easy to handle.

There is no.

Moreover, the structure of the shelf of the product display stand includes a leg attachment part made of a square cylindrical member, and a leg part with an engaging member having a U-shaped cross section at the base end that engages with the leg attachment part. Since it is a small part of a leaf spring with a pin disposed inside the leg attachment part, the manufacturing of the display stand is extremely simplified, the cost can be reduced significantly, and there are almost no failures, so it can be used for a long period of time. It has the great advantage of being able to be used in many situations.
