Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saw sheath for inserting a saw blade having exposed dangerous saw teeth when the saw is not used, and covering the saw blade in a safe state.

[0002]

2. Description of the Related Art Generally, a saw sheath of this type is mostly made of a cylindrical wooden or synthetic resin. It is made of a material that is easily damaged by biting. However, in the past, there was no saw sheath in the portion of the saw sheath that was in contact with the saw blade, for which effective measures were taken to avoid damage.

[0003]

Therefore, when the saw blade is inserted into or taken out of the sheath, the inner wall portion of the sheath, particularly, which comes into contact with the saw teeth, is gradually scraped and cut.
And such a phenomenon appears more remarkably in the case where the saw blade is put into and taken out of the saw sheath frequently or when it is severely rough. Not only is the saw tooth exposed and exposed to danger, which is unfavorable in terms of safety, but also the operation of inserting and removing the saw blade into and out of the sheath of the saw may cause the sheath to be further damaged by being caught at the cutting damage point of the sheath. On the other hand, there was an inconvenience that smooth operation was hindered and work efficiency was reduced.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a saw sheath that has solved the above-mentioned problem with an extremely simple configuration and at a low cost.

[0005]

According to the present invention, a saw sheath is provided.
In a sheath of a saw having a sheath 2 capable of covering and storing a saw blade 1 therein, and a saw insertion slot 3 formed to receive the saw blade 1 in the sheath 2, a sheath 2 is provided. When the saw blade 1 is put in and out of the saw blade, a hard roller member 4 capable of guiding and contacting the saw blade 1 at least near the saw tooth side edge of the saw blade 1 in the vicinity of the insertion slot 3 for inserting the saw blade, It is characterized in that it is configured to be rotatably mounted on the sheath 2.

Here, "at least the saw-tooth side edge of the saw blade 1" means both sides of the saw-tooth side edge of the saw blade 1 and the back side edge of the opposite saw blade. In addition, it means that only one side of the sawtooth side edge is included. The hard roller member refers to a roller member formed of a material such as a synthetic resin, a synthetic rubber, or a synthetic aluminum having a hardness that is not harder than the steel material forming the saw blade.

[0007]

When using the saw sheath according to the present invention, the sheath 2 is usually hung on the waist by a hanging leather or the like integrally attached to the sheath. In order to store the saw blade 1 in the sheath 2, the handle 12 of the saw 5 is held, and the saw blade 1 is gradually inserted deeply into the insertion slot 3 of the sheath 6 for inserting the saw blade. Eventually, the sheath 6 is stored and held in a safe state in which the saw blade 1 is not exposed, and the handle 12 of the saw 5 is kept exposed from the sheath body 2. On the other hand, in order to pull out the saw blade 1 from the sheath 2, simply hold the handle 12 of the saw 5 with one of the palms and pull it, and the saw blade 1 can be easily pulled out of the sheath 2 through the insertion slot 3 for inserting the saw blade. It can be extracted.

It should be noted that when the saw blade 1 is put into and taken out of the sheath 2, the saw blade 1 faces the saw-tooth side edge of the saw blade 1 in the vicinity of the insertion slot 3. do it,
Since the guide member is brought into contact with the hard roller member 4 rotatably mounted on the sheath body 2, the operation of taking the saw blade 1 into and out of the sheath body 2 is performed extremely smoothly and lightly.

[0009]

[Effects of the Invention] Since the sheath of the present invention has the above-described configuration and operation, it has the following effects. When the saw blade is taken in and out of the sheath, the guide is smoothly and lightly guided by the hard roller member without being caught, so that the operation is quick and easy, and the working efficiency can be further improved. . Further, as in the prior art, an inconvenience in which the saw blade bites into the inner wall of the sheath and the saw blade or the sheath body is damaged is prevented beforehand, and moreover, the operation of putting the saw blade into and out of the sheath body is frequent and intense. Even in a rough case, since the sheath body is not cut and damaged, the saw teeth are exposed from the cut and damaged portion of the sheath body, and it is possible to avoid a situation in which the saw blade is exposed to a dangerous state, and to perform a safe operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. 1 to 3 show an embodiment of a saw sheath according to the present invention. FIG. 1 is a perspective view of the saw sheath, and FIG. 2 shows a state where the saw is inserted into the saw sheath of FIG. FIG. 3 is a cross-sectional view as viewed from the direction of arrows III-III in FIG. 1, and FIG. 4 is a partially enlarged vertical cross-sectional view as viewed from directions of arrows IV-IV in FIG.

In these figures, the saw sheath according to the present invention is made of wooden or synthetic resin, and is a tubular sheath having a substantially rectangular cross section including a front wall 7, a rear wall 8, a left side wall 9, and a right side wall 10. The saw blade 1 can be covered and stored inside the body 2. In addition, at the upper end of the sheath 2, an insertion slot 3 for inserting the saw blade 1 is formed to accommodate the saw blade 1, and the lower end of the sheath 2 does not abut the tip of the saw blade 1. Opening 11
Is formed.

The front wall 7 of the insertion slot 3 has a substantially semicircular cutout 13 at the center of its upper end so that the handle 12 of the saw 5 can be seen. The hard roller members 4 are provided on both the left and right sides of the notch 13 of the front wall 7 of the sheath 2.
A support part 14 for supporting the shaft 4 is formed. In other words, as shown in FIG. 4, the support portion 14 is formed so as to protrude bifurcated above the left side wall 9 and the right side wall 10, respectively, and the support portions 14, 14 of the front wall 7 and the rear wall 8 are formed. The hard roller members 4 and 4 are axially mounted between the
The one hard roller member 4 faces the saw-tooth side edge of the saw blade 1 and the other hard roller member 4 faces the back side edge of the saw blade 1. The saw body 1 can be guided when the saw body 1 is brought into contact with the body 1 and the sheath body 1 is moved in and out of the sheath body 2.

The hard roller members 4 and 4 are hollow members 15 (specifically, made of a material such as synthetic resin, synthetic rubber, synthetic aluminum, etc.) having a hardness that is not harder than the steel material forming the saw blade 1. In the embodiment, hard urethane is used), and a screw rod 16 that is inserted through the hollow member 15 and rotatably attaches the hollow member 15 to the sheath 2 in a rotatable manner. As shown, the bearing 14 has a bolt head that can face the recess 17 on one side, and the other side has a tail end that can face the recess 18 of the rear wall 8, and this tail end is axially moved by the Casinu. The retaining has been made.

As described above, hard urethane is used for the hollow member 15 of the hard roller member 4 in the present embodiment, and the hollow member 15 is coated with a fluorescent paint. Therefore, for example, when used in a cluttered environment such as a mountain forest, even if the saw sheath is neglected or misplaced carelessly at that location, it can be easily found without losing the saw sheath. There are advantages that can be done. Reference numeral 19 denotes a hanging leather for hanging the sheath 2 on a belt (not shown) which is fastened to the waist. The hanging leather 19 is joined to the side of the insertion opening 3 for inserting the body of the sheath 2 with rivets 20, 20. Is done.
