Description

  In the present invention, a belt insertion ring made of leather or synthetic fiber that passes a belt is formed on the upper part of the substrate, and the substrate has one or a plurality of tool mounting portions, and is suspended from the belt that an operator or the like tightens. It relates to a working case to be used.

  Various works are necessary for the construction of buildings such as buildings or bridges, road construction, etc., and various tools corresponding to the various work contents are used. For example, pliers or midget cutters are used for cutting mild steel wires, and hackers (binding tools) are used for bundling reinforcing bars. The tool is frequently put in and out of the work case attached to the waist.

In other words, the worker puts a tool such as a midget cutter, pliers or hacker to be used in the work case suspended from the belt, enters the work site, and when using a tool such as a midget cutter, removes the midget cutter from the work case. If you do not use a tool such as a midget cutter, keep the tool such as a midget cutter in the work case, rest, and do another work. To go.
The same applies to other work other than cutting work and bundling work, etc. There are various work cases made to put midget cutters and other tools, and the applicant company has also developed various work cases. For some of the results, patent applications or utility model registration applications have been filed (Patent Document 1: Japanese Patent Laid-Open No. 2003-82856, Patent Document 2: Japanese Patent Laid-Open No. 2003-80474).

In such work cases, there is a work case in which a belt insertion ring for passing a belt is formed on the upper part of a substrate made of leather or synthetic fiber, and various tool storage portions are formed on the front and side surfaces of the lower part of the substrate.
FIG. 2 is a perspective view showing an example of such a work case (case for housing a midget cutter). In the figure, reference numeral 2 denotes a substrate made of leather, synthetic fiber, or the like. An upper portion 4 of the substrate 2 is folded back, and an upper end is fixed to the back surface of the substrate 2 to form a belt insertion ring 6.

Reference numerals 8, 8, 8, and 8 denote rivets for fixing the upper end of the substrate 2 to the back surface of the substrate 2, and are fixed by caulking. In FIG. 2, three rivets 8, 8, 8 out of four rivets 8, 8, 8, 8 appear, but one rivet 8 does not appear.
Reference numeral 10 denotes a pocket-forming piece, which is made of, for example, leather or synthetic fiber. The both-side pieces and the lower edge of the pocket-forming piece 10 itself are fixed on the both sides and the lower edge of the front lower portion of the substrate 2 so An open tool storage pocket 12 is formed. 14, 14,... Are fixing members for fixing the substrate 2 and the pocket forming piece 10, and 16 is a sewing portion for fixing the substrate 2 and the pocket forming piece 10.

Such a working case shown in FIG. 2 is a state in which a belt for fastening a worker's trousers or a work-dedicated belt is passed through the belt insertion wheel 6 to be suspended from the belt, and a tool, for example, When a midget cutter is inserted and it is necessary to use it for work, the tool, for example, a midget cutter, is taken out and a work, for example, a cutting work of a mild steel wire or the like is performed.
Note that the structure, shape, and storage form of the tool storage section differ depending on the type of tool, and there are many types of work cases. The one shown in FIG. 2 is merely one of the conventional examples.

By the way, when the working case is used, a portion made of leather or synthetic fiber is deteriorated due to secular change, and in particular, the width direction of the belt of the folded portion 4 to form the belt insertion ring 6 of the substrate 2. The part in contact with the lower edge is subjected to local concentrated load by the belt and concentrated fatigue occurs there, so there is a problem that the crack deteriorates first, then the crack expands rapidly and the life is exhausted, The service life was relatively short, which was a disadvantage of the conventional work case.
FIG. 3 is a rear view of the case showing such a problem. In FIG. 3, parts that are the same as those in FIG. 2 are given the same reference numerals, and parts that are not shown or do not appear in FIG.

In the figure, 18 is a belt passed through the belt insertion wheel 6, and 20 is a lower edge portion in the width direction of the belt 18.
And it begins to tear from the part which contact | connects the lower edge part 20 in the width direction of the belt 18 of the side edge of one side of the said pocket formation piece 10 (for example, the left side in a figure). 22 is a tear.
Once the tear 22 occurs, the tear 22 rapidly expands and becomes unusable as a work case in a relatively short time.

  In this way, the fold 22 can be formed in the folded portion 4 of the substrate 2 made of leather or synthetic fiber of the working case, because the working case is suspended while walking on the belt 18, or the working case is something, Each time the structure is touched or a tool such as a midget cutter is inserted or removed from the work case, the lower side of the work case is swung away from the operator's body. This is because concentrated fatigue occurs in contact with the lower edge.

The tear 22 does not occur while the number of swings is small, but it has been unavoidable in the past that the tear 22 occurs when the number of swings increases.
In the example of FIG. 3, a tear 22 has occurred from the right side of the folded portion 4 in the same figure, but a tear may also occur from the left side, and it seems that it is determined by the operator's heel or the like. is there.

  In the present invention, due to secular change, the belt inserted into the belt insertion ring made of leather or synthetic fiber on the upper part of the work case substrate can be ruptured by the belt, which spreads and becomes unusable. The present invention has been made to solve the problem that it is difficult to extend the service life, and an object thereof is to provide a work case with a long service life.

The working case according to claim 1 is made of leather or synthetic fiber on the upper part of the substrate, and a belt insertion ring through which the belt is passed is formed. The working case having one or a plurality of tool mounting portions on the substrate, A reinforcing piece is fixed to a portion of the substrate that is in contact with the lower edge in the width direction of the belt that has passed through the belt insertion wheel and / or the back side thereof.
In addition, the belt insertion ring on the upper part of the base body is integrated with a so-called so-called substrate (made of leather or synthetic fiber) formed by, for example, folding the upper part of the substrate to the back side and fixing the upper end to the back surface of the substrate. There may be a case where it is separate from the substrate. In this case, the belt insertion wheel is made of leather or synthetic fiber.
Further, even when the belt insertion wheel is integrated with the substrate, the belt insertion ring is not necessarily folded, but may be formed integrally with the substrate by other means.
