Abstract

<P>PROBLEM TO BE SOLVED: To inexpensively provide metallic fittings for a bar for merchandise display, which are excellent in mechanical strength and hardly deformed even when a large load is imposed. <P>SOLUTION: The metallic fittings 4 for reception, which is manufactured by bending a steel plate simultaneously with punching the steel plate by press working, includes: a substantially triangular plate-like swelling part 5 where hooks 7a-3c to be engaged with a supporter 1 are formed at the rear edge by punching; and an insertion part 6 which is formed at the swelling edge 9 of the swelling part by bending to have a perpendicular plane, so as to be inserted into the opening end of the bar 2 for merchandise display. The insertion part is, furthermore, perpendicularly bent inward in the upper side edge 10 and the lower side edge 11 respectively, so as to have a U shape cross section. The widths of the upper side edge 10 and the lower side edge 11 are set, so as to allow the upper side edge and the lower side edge to reach the upper surface 9a and the lower surface 9b of the swelling edge in the swelling part. Thus, the swelling edge 9 is held from above and below between the bent upper and lower side edges 10, 11. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a commodity display bar receiving bracket for supporting a commodity display bar on a support.

The following Patent Document 1 shows a structure in which a commodity display bar that supports a commodity display hook or the like is supported on a column so that the height can be adjusted. Moreover, the following patent document 2 shows the structure of a hook bar receptacle similarly.
Japanese Patent Laid-Open No. 9-271431 Japanese Patent Laid-Open No. 11-76015

In the product display bar, generally, a metal square pipe of 14 mm × 32 mm is cut to an appropriate length, receiving metal fittings (also referred to as brackets) are inserted into both opening ends, and the receiving metal fittings are engaged with support columns. It is configured so that it can be supported at an appropriate height, but since the load on the bar, such as a product, is concentrated on the bent edge of the metal fitting, the bent edge is twisted under the load, There was a risk of deformation.
Conventionally, this receiving metal fitting has been manufactured by punching a steel sheet having a thickness of about 2 to 3 mm by pressing and bending it at the same time, and in order to increase its load resistance, mechanical strength, etc., the bent edge is attached to a bag. In some cases, the strength is increased by welding into a shape or by narrowing the bent edge in advance when the steel plate is pressed and forming it into a bag shape.

However, press dies and equipment that can process thick steel plates are expensive because the required press pressure is very high, and manufacturing costs are high, and burrs are easily generated during molding, which requires man-hours to remove them. was there. Further, although it was possible to increase the strength by welding the bent edge in a bag shape, there was a problem that there were many factors for increasing the cost, such as increasing the number of processes.
The present invention solves such conventional problems, makes it possible to easily produce a bar holder for a product display with a small number of steps, which has excellent mechanical strength and is difficult to be deformed even when a heavy load is applied. The production cost is going to be.

  Therefore, the present invention is a receiving metal fitting manufactured by punching a steel plate by pressing and bending the steel plate at the same time, and a substantially triangular plate-like overhang portion formed on the trailing edge by a hook that engages with a column. And an insertion part formed so as to be inserted into the opening end of the bar for product display by being bent at a right angle to the extension edge of the extension part, the insertion part further comprising an upper edge and a lower edge Each of the upper edge and the lower edge so that the upper edge and the lower edge reach the upper surface and the lower surface of the protruding edge, respectively. By setting the width of the lower edge, the protruding edge of the protruding portion is sandwiched from above and below by the bent upper edge and the lower edge.

  According to the commodity display bar receiving metal fitting of the present invention, the load applied to the insertion part from the commodity display bar is supported and supported by the overhanging edge of the overhanging part via the upper edge and the lower edge of the insertion part. Therefore, the strength is remarkably increased and the durability is increased without concentrating the load on the bent edge. In addition, since the number of processes is not increased, the manufacturing cost is reduced.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a merchandise display device using a metal fitting according to the present invention, and FIG. 2 is an exploded perspective view thereof. In the figure, 1 is a column having a number of engaging holes formed at regular intervals on the front surface, 2 is a product display bar made of a metal square pipe cut to a certain length, and 3 is detachable on the bar The product hanging hook 4 to be engaged is a receiving bracket for supporting the bar.

  The receiving metal fitting 4 is manufactured by punching a 2.6 mm thick steel sheet by pressing and bending it at the same time. As shown in an enlarged view in FIGS. And an insertion portion 6 connected to the overhanging portion 5 in a plane right-angle bent shape via a bent edge 8. FIG. 6 shows a development view of the metal fitting 4, that is, a state after the steel plate is punched and before being bent. Hooks 7 a to 7 c are formed on the rear edge of the overhanging portion 5 by punching a press, and the hooks can be engaged with arbitrary engagement holes of the support column 1. Reference numeral 12 denotes a small hole formed in a part of the overhanging portion 5, and the small hole is used for hanging when plating the receiving metal fitting.

  Further, the insertion portion 6 bends the tip of the overhanging edge 9 of the overhanging portion 5 at a plane right angle at the bent edge 8, and the upper edge 10 and the lower edge 11 of the insertion portion 6 are respectively perpendicular to the inside. The insertion portion 6 can be inserted into the opening end of the product display bar 2 by being bent into a U-shape. Further, the upper edge 10 and the lower edge 11 are bent by setting the widths of the upper edge 10 and the lower edge 11 so that they reach the upper surface 9a of the overhanging edge 9 and the lower surface 9b of the overhanging edge 9. The overhanging edge 9 is sandwiched from above and below by the upper edge 10 and the lower edge 11.

In the receiving metal fitting 4 configured in this way, the load applied to the insertion portion 6 from the product display bar 2 is applied not only to the bent edge 8 but also to the overhanging edge 9 via the upper edge 10 and the lower edge 11. Therefore, the burden on the bent edge 8 is reduced, and the breakage and deformation are avoided. In particular, since the protruding edge 9 is sandwiched between the upper edge 10 and the lower edge 11 from above and below, even if a twisting force is generated in the product display bar 2, the twisting force is transmitted through the upper edge 10 and the lower edge 11. It is loaded on the upper and lower surfaces of the leading edge 9 and has a very strong strength against twisting force.
Although not shown, separation may be prevented by spot welding the lower surface of the upper edge 10 and the upper surface of the overhanging edge 9. Similarly, the upper surface of the lower edge 11 and the lower surface of the overhanging edge 9 can be spot-welded.
