Description

[Detailed Description of the Invention] For the caps of so-called bags such as handbags and pouches, a metal fitting called a top structure member is used which has an open top and can freely come into contact with the other side on one side.

This invention relates to a ring material that is fixed to such a sky structure material.

Conventional cover ring materials had a flat bottom surface, so when fixing them to the roof structure material by welding, etc., they were positioned by eye.
As a result, they did not arrive straight along the center line but were bent, or wobbly and distorted.

For this reason, the defective rate of the product reached about 30%, which was not only uneconomical, but also because the product was not attached accurately, the adhesion strength could not be maintained.

Furthermore, in order to avoid the above-mentioned drawbacks and to achieve accurate measurements, most of the work was done manually, resulting in extremely poor workability.

Therefore, the inventors of the present invention initially attempted to draw lines on the underside of the cover ring material, but although it was possible to position the material, it did not solve the problem of the product being distorted. I couldn't figure it out.

Next, I tried making a groove protruding from the underside of the ring material, but if it was too shallow, the above purpose could not be achieved, and if it was too deep, the strength of the material itself would be lost, so it was difficult to obtain a groove of an appropriate depth. There wasn't.

Therefore, the present inventors developed a cap ring material that not only improves positioning accuracy but also improves fixing strength and workability by making the groove deep enough to hold the internal structure. That's what I did.

In other words, this invention is based on a ring material that is fixed to a cap with an open top and one side that can freely come into contact with the other, and a filament that holds the internal structure of one of the caps on the lower surface of the cap. It is characterized by having a groove formed therein.

This invention will be explained based on the embodiment shown in the drawings.
Reference numeral 1 denotes a quarter-section wire member having an open upper part 2 and integrally forming an inner structure part 3 and an outer structure part 4, and is called a top structure member.

Reference numeral 5 denotes a cap formed by connecting a pair of left and right ceiling members 1 with pins or the like, and the inner structure portion 3 on one side and the inner structure portion 3' on the other side are in contact with each other when the cap is tightened. .

Reference numeral 6 denotes a cover ring material having a height of about 2 mm (example in Figure 1) to 1.5 mm (example in Figure 2), and a roof ring material 6 having a height of about 2 mm (example in Figure 1) to 1.5 mm (example in Figure 2). In the following, it is fixed to the internal structure part 3 of the roof structure 1).

That is, a linear groove 8 is bored in the lower surface 7 of the cover ring member 6 so as to hold the inner structure 3, and the top 9 of the inner structure 3 of the top structure member 1 is fitted into the groove 8. and secure by welding, etc.

The shape of the upper surface of the cover ring material 6 is a planar shape with rounded corners in the example shown in FIG. 1, and is curved in the example shown in FIG. 2, but is not limited to any particular shape.

The depth of the groove 8 is 0.9 mm in the example shown in FIG. 1 and 0.7 mm in the example shown in FIG.
From the point of view of preventing the roof member 1 from being distorted or bent, the height and thickness of the cover member 6 may be approximately the same.

The shape of the groove 8 does not matter, but if it is curved as shown in the examples in Figures 1 and 2, it will be easier to cut the groove.
(not shown), the fitting to the ceiling member becomes even more reliable.

In addition, in the illustrated example, the groove 8 is connected to the central protrusion 1 in both FIGS. 1 and 2.
0 is placed symmetrically on the left and right, but this will improve the design effect.

However, only one groove 8 may be provided on the side of the internal structure to be fixed.

11 is the outer cover of a handbag or purse.

Therefore, if the present covering ring material 6 is used, the inner structure 3 of the top structure member 1 may be fitted into the groove 8 of the covering ring material 6 and fixed by welding or the like. This eliminates the need for positioning and distortion correction, which were previously required.

Therefore, productivity is improved, and there is no risk of manufacturing defective products even by unskilled workers.

In addition, since the cover ring material 6 firmly holds the inner structure 3 of the ceiling structure material 1 in the groove 8, the fitting is reliable, and the fixing area increases, so that the fixing strength is increased, and from the top structure material 1. There is no peeling.

In this way, according to this invention, when fixing the cover ring material to the sky structure member, the positioning can be performed accurately and easily without reducing the strength of the cover ring material, and the fixation is reliable and there is no distortion or bending. This has the effect of increasing adhesion strength and improving workability.

Further, there is an effect that the defect rate of products obtained by such operations is completely eliminated.
