Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a saw sheath for inserting a saw blade having an uncovered dangerous saw tooth when the saw is not used and covering and storing the saw blade in a safe state.

[0002]

[Prior art]

 In general, most of the sheaths of this type of saw are made of tubular wood or synthetic resin, and when the saw blade is put in and taken out, when it comes in contact with the saw blade, friction resistance is caused or the saw teeth bite. Made of easily damaged material. However, in the past, no part of the saw sheath that comes into contact with the saw blade had any effective measures to be taken to avoid the damage.

[0003]

[Problems to be solved by the device]

 Therefore, when the saw blade is put in and taken out of the sheath, the part of the inner wall of the sheath that comes into contact with the saw teeth is gradually shaved and cut. And, such a phenomenon becomes more remarkable when the operation of putting the saw blade in and out of the saw sheath is frequent or severely rough, and if it is left unattended, it will eventually disappear from the cut and damaged portion of the sheath. Not only is the saw blade exposed, it is exposed to a dangerous condition and is not preferable in terms of safety, but the operation of putting in and out of the saw sheath of the saw blade also catches on the cut damage point of the sheath, further damaging the sheath. On the other hand, there were some inconveniences such as smooth operation being hindered and work efficiency being reduced.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a saw sheath that solves the above problems with a very simple configuration and at a low cost.

[0005]

[Means for Solving the Problems]

 The sheath of the saw according to the present invention comprises a sheath body 2 capable of covering and storing the saw blade 1 therein, and a saw blade insertion opening 3 formed to store the saw blade 1 in the sheath body 2. In the sheath of the saw, when the saw blade 1 is put in and taken out of the sheath body 2, the saw blade 1 is opposed to at least the 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 a hard roller member 4 that can be brought into guide contact is configured to be rotatably attached to the sheath body 2 by a shaft.

[0006] Here, "at least the saw-tooth side edge of the saw blade 1" refers to both sides of the saw-tooth side edge of the saw blade 1 and the back side edge of the saw blade on the opposite side. In addition, it is meant to include the case where only one side of the serrated side edge is inserted. The hard roller member is a roller member formed of a material such as synthetic resin, synthetic rubber, or synthetic aluminum having a hardness not higher than that of the steel material forming the saw blade.

[0007]

[Action]

 Thus, when the saw sheath according to the present invention is used, the sheath body 2 is usually hung on the waist with a hanging leather or the like integrally attached to the sheath body 2. To store the saw blade 1 in the sheath body 2, the handle portion 12 of the saw 5 is held, and the saw blade 1 is gradually inserted deeply into the saw blade insertion insertion opening 3 of the sheath 6. 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 body 2, simply grasping the handle 12 of the saw 5 with one palm and pulling it allows the saw blade 1 to easily insert the saw blade insertion opening 3 from the sheath body 2. It can be pulled out through.

When operating the saw blade 1 in and out of the sheath body 2, it should be noted that the saw blade 1 faces the side edge of the saw blade 1 near the saw blade in the vicinity of the saw blade insertion opening 3. Since it is guided and contacted by the hard roller member 4 rotatably attached to the sheath body 2, the operation of putting the saw blade 1 in and out of the sheath body 2 can be carried out very smoothly and lightly.

[0009]

[Effect of device]

 Since the sheath of the saw according to the present invention has the above-described structure and operation, it has the following effects. When the saw blade is put in and out of the sheath, it is guided smoothly and lightly by the hard roller member without getting caught, so the operation is quick and easy, and the work efficiency can be further improved. . In addition, as in the conventional case, the inconvenient situation that the saw blade strongly digs into the inner wall of the sheath body and damages the saw blade and the sheath body is prevented, and the operation of putting the saw blade in and out of the sheath body is frequent. Even in severe and rough conditions, the sheath body is not damaged by cutting, so it is possible to avoid a situation in which the saw blade is exposed from the cut and damaged portion of the sheath body, which exposes it to a dangerous state, and it is possible to perform safety work. it can.

【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. 1 to 3 show one 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 in which the saw is inserted into the saw sheath of FIG. FIG. 3 is a plan view, FIG. 3 is a horizontal cross-sectional view as seen from the arrow III-III direction in FIG. 1, and FIG. 4 is a partially enlarged vertical cross-sectional view as seen from the arrow IV-IV direction in FIG.

In these drawings, a saw sheath according to the present invention is made of wood or synthetic resin, and has a cylindrical sheath having a substantially rectangular cross section, which includes 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. A saw blade insertion opening 3 is formed at the upper end of the sheath body 2 for accommodating the saw blade 1, and the tip of the saw blade 1 does not hit the lower end portion of the sheath body 2. Is formed in the opening 11.

The front wall 7 of the insertion slot 3 for inserting the saw blade has a substantially semicircular cutout 13 at the center of the upper end thereof so that the handle 12 of the saw 5 can be seen. Then, bearing portions 14 for axially supporting the hard roller members 4, 4 are formed on both the left and right sides of the notch 13 of the front wall 7 of the sheath body 2 between them. In other words, as shown in FIG. 4, the support portion 14 is formed in a bifurcated shape above each of the left side wall 9 and the right side wall 10, and the support portions 14, 14 and the rear wall of the front wall 7 are formed. Since the hard roller members 4 and 4 are axially mounted between the hard roller members 4 and 8, the one hard roller member 4 is opposed to the saw blade side edge of the saw blade 1 in the saw blade insertion insertion port 3 of the sheath body 2. In addition, the other hard roller member 4 faces the back side edge of the saw blade 1 and contacts the saw blade 1, and guides the saw blade 1 when operating the saw blade 1 in and out of the sheath body 2. You can do it.

The hard roller members 4 and 4 are hollow members 15 (specifically, made of synthetic resin, synthetic rubber, synthetic aluminum or the like having a hardness not higher than the steel material forming the saw blade 1). In this embodiment, hard urethane is used) and a screw rod 16 which is inserted into the hollow member 15 and rotatably shaft-attaches the hollow member 15 to the sheath body 2. The screw rod 16 is shown in FIG. As shown in FIG. 3, the bearing portion 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. Has been prevented.

As described above, hard urethane is used for the hollow member 15 of the hard roller member 4 in this embodiment, but the hollow member 15 is coated with fluorescent paint. Therefore, for example, when used in a cluttered environment such as a forest, and even if the saw pod is left carelessly or misplaced in that place, it can be easily found without losing the saw pod. There are advantages. Further, 19 is a hanging leather for hanging the sheath body 2 on a belt (not shown) which is fastened to the waist. The hanging leather 19 is joined to the saw body insertion insertion port 3 side of the sheath body 2 with rivets 20 and 20. To be done.
