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. .

[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 products are moved to display and sell products, but if the legs are fixed to a mounting table when used, it is extremely inconvenient for storage and transportation.

For this reason, foldable legs such as those described in Japanese Utility Model Application Publication No. 47-7101 are also used for display stands and are widely used.

The foldable legs in this Utility Model No. 47-7101 are
When the upper part of the cylindrical leg is foldably pivoted around a shaft on a U-shaped base having a top plate, a spring is wound around the cylindrical leg and the shaft plate is fitted across the cylindrical leg in contact with the lower end of the U-shaped base and parallel to the axis. Then, one end of the shaft plate is bent to form a push button, and a branch shaft plate is provided so as to extend along the inner surface of the cylindrical leg in a non-rotating direction, and a stop plate provided on the branch shaft plate is attached to the side surface of the U-shaped base. It is engaged in a provided stop hole so that it can move in and out.

Therefore, even if the shaft plate is thin and thin, the supporting force of the table plate when the cylinder leg is raised is good, and as a result of the integrated stop plate and push button engaging and supporting the U-shaped base and the cylinder leg, the cylinder leg This has the effect that the shaft connecting the U-shaped base and the U-shaped base can be extremely thin.

However, product display stands are required to have as much strength as possible because they typically hold products of various weights, from light products to heavy products.

Therefore, the display stand consisting of legs and a U-shaped base having the structure described in the above publication cannot withstand the weight of the products placed on it, and cannot be used for displaying many products. There are many problems in practical use, such as the risk that the legs will instantly become folded if the push button is pressed carelessly.

In view of the current situation, this invention aims to provide a product display stand that does not cause play in the legs even when a large number of heavy products are placed on it, has an extremely small number of parts, and has a simple structure. It is.

[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 table for placing the products, and the leg attachment parts are foldably pivoted. The structure includes a U-shaped frame member, and a leg portion having a shaft member having a circumferential wall in contact with a side wall of the leg attachment portion fixed at the base end in a state perpendicular to the leg attachment portion. Fix the U-shaped opening on the inside of the back surface of the mounting table, and insert the shaft member into the leg mounting part so that the mounting side of the leg is located at the back of the U-shape. A shaft member is pivotally supported by a pivot pin on the leg attachment part on the side surface near the opening of the shaft member, and the shaft member normally protrudes from the hole provided at one end of the shaft member due to the biasing force of a spring within the shaft member, and the protrusion is eliminated by pressing. A spring-loaded pin is provided, and a through-hole that engages with the spring-loaded pin is provided in the inner part of the leg attachment part, and when the leg is in an upright state, the spring-loaded pin engages with the through-hole, and the spring is released by pressure. The attachment pin is disengaged from the through hole, and the leg portion is folded along the back surface of the mounting table using the pivot pin as a fulcrum.

[Effect]

In the product display stand of this invention, a leg attachment part 2 formed of a frame member is provided on the back surface of a placing table 1, and a leg part 3 having a shaft member 4 is pivotally supported thereon using a pivot pin 7. Spring-loaded pin 1 provided at the other end of the shaft member 4
By fitting and protruding the 0 into the through hole 9 provided in the leg attachment part 2, the leg 3 is maintained in a normal open state and the mounting table 1 is securely held.

In addition, when folding the leg 3, as is particularly clear in FIG. By rotating it, it will be in the folded state, and by reversing it, it can be put into the normal usage state.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

Fig. 1 is a side view showing an example of a product display stand of this invention, and Fig. 2 is an assembled perspective view thereof, in which 1 is a product placement stand, and 2 is a leg mounting portion provided on the back side of the placement stand 1. This leg attachment part 2 is made up of U-shaped frame members, each of which is fixed to the four corners of the back surface of the mounting table 1, and the U-shaped openings are connected to the mounting table 1. Each pair is provided facing each other on the inside of the back surface.

Although not shown, the frame member has a horizontally bent flange portion in contact with the back surface of the mounting table, and is fixed with screws.

A pin hole 8 is provided to pass through the side surface near the U-shaped opening of the leg attachment portion 2, and a through hole 9 is provided at the back of the U-shaped opening at the other end, that is, at the abutting portion. be.

Reference numeral 3 denotes a leg portion, the base end of which is tubular and can be fitted into the frame member of the leg attachment portion 2, and a shaft member 4 having approximately the same length as the frame member is in a state where the shaft members 4 are orthogonal to each other. It is attached integrally by welding.

Note that 5 is a caster, and 6 is a reinforcing plate provided between the shaft member 4 and the leg portion 3 to maintain a correct angle and improve the strength thereof.

As shown in FIG. 3, the shaft member 4 has a pin 10 whose tip protrudes from a hole 10a provided deep inside.
is installed inside the spring 11 and stopper 12.
A spring-loaded pin 10 (same as pin 10) is pressed so that the pin 10 normally protrudes outside due to the biasing force of the spring 11, and when pressed, the pin 10 resists the biasing force of the spring 11 and cancels the protrusion. (Indicated by figure number.)
It incorporates the following mechanism.

In addition, at the stopper 12 part of the shaft member 4,
A pin hole 13 is provided which penetrates the shaft member 4 and the stopper 12 and is pivotally supported.

The leg portion 3 having the shaft member 4 having such a configuration has the pin hole 13 of the shaft member 4 inserted into the pin hole 8 of the leg attaching portion 2.
When the shaft member 4 is inserted into the frame member of the leg attachment part 2, the spring-loaded pin 1 is inserted through the pivot pin 7 with the
0 matches the through hole 9 and is configured to fit and protrude.

The legs 3, 3 may be pivoted to stand upright on the floor at four points.

[Effect of idea]

The fixing structure of the legs in the product display stand of this invention is based on a leg attachment part made of a U-shaped frame member, and a shaft member provided at the base end of the leg is connected to a pivot pin in this leg attachment part. Since it is pivoted, the engagement between the leg attachment part and the leg part is extremely strong, and can sufficiently withstand the display and display of heavy products, with no horizontal sway in particular.

Further, the shaft member and the leg are configured to form a substantially right angle, and when the leg is in an upright state, the mounting table is supported with the side wall of the shaft member in parallel contact with the back surface of the mounting table. Therefore, even if the spring-loaded pin is inadvertently pushed, it will not be folded unless an active folding operation is applied to the legs, and it can be used stably.

Furthermore, when folding the legs, it is possible to easily make it into a compact state by disengaging the spring-loaded pin from the through hole and folding the legs. The display stand is easy to carry, does not take up much space for storage, and can be handled very conveniently, and one of its major features is that it can be easily opened and folded with a single touch. It is.

Furthermore, the product display stand of this invention has foldable legs made up of an extremely small number of parts, so the display stand is simple to configure and easy to manufacture, and will not break down even after repeated use. It has many practical advantages, such as being able to be used for a long period of time.
