[Detailed description of the invention]

[0001]

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

[0002]

2. Description of the Related Art Conventionally, this kind of saw sheath is susceptible to expansion and contraction due to temperature change and humidity change, and the saw blade in the sheath is loose and cannot be easily pulled out. It is easy to happen. Inconvenient situations such as forcibly pulling out the saw blade that has become difficult to pull out and injuring your hand, or the sheath or saw falling off easily and falling on your feet, and sufficient safety cannot be maintained Is known to occur.

In order to prevent such a situation, for example, a retaining member such as a leaf spring for pressing and biasing the back side of the saw blade is integrally provided relatively near the inlet of the saw blade inside the sheath. Even if the sheath is affected by temperature change or humidity change, the saw blade stored in the sheath can always put the saw blade into and out of the sheath with moderate hardness, regardless of those. Such a saw sheath has been proposed.

[0004]

However, in the case of such a saw sheath, the following various inconveniences occur. In other words, first of all, since the pull-up member is mounted inside the sheath, it is difficult to manufacture or it takes time to manufacture,
Not only is the cost increased, but it is not suitable for mass production.
Second, the back side of the saw blade is urged downward by the retaining member, and the saw blade is pressed against the retaining member and the abdominal wall surface in the sheath. However, the saw blade bites into the inner wall of the sheath and sharpens the inner wall of the sheath, so that not only the sheath itself is damaged, but also the stored saw blade itself is also damaged. Third, since the retaining member is mounted relatively close to the insertion port inside the sheath, elasticity such as a spring is always applied when the saw is inserted into or removed from the sheath. And other problems.

An object of the present invention is to provide a saw sheath that solves the above-mentioned problem with an extremely simple structure and at a low cost.

[0006]

According to the present invention, a saw sheath is provided.
A sheath body 5 having an insertion port 4 formed therein for accommodating the saw blade 3 of the saw 2 between the pair of side walls 1 and 1, provided at the tip of the sheath body 5 and housed in the sheath body 5. An incision 6 for exposing a part of a certain saw blade 3 and a retaining member 7 integrally attached to the sheath body 5 and capable of facing the exposed portion of the saw blade 3 stored in the sheath body 5. Equipped,
The retaining member 7 is characterized in that, when the saw blade 3 is stored, an elastic force for pressing and holding the saw blade 3 in the thickness direction is applied to the retaining member 7.

[0007]

When using the saw sheath according to the present invention, the sheath is usually attached to the hanging leather 1 integrally attached thereto.
It is hanging on the waist at 5 mag. In order to store the saw 2 in the sheath, the handle 8 of the saw 2 is held, and the saw blade 3 is gradually inserted into the insertion port 4 of the saw 2. Eventually, the saw blade 3 reaches an incision 6 provided at the distal end of the sheath body 5, and a part of the saw blade 3 is exposed from the incision 6. Since the member 7 is facing,
The saw 2 is securely stored and held in the sheath body 5. Then, the entire saw blade 3 is covered with the sheath main body 5 to keep the saw blade 3 in a safe state in which the saw blade 3 is not exposed, and the handle 8 of the saw 2 is maintained in a state as shown in FIG. It is dripping.

On the other hand, in order to pull out the saw blade 3 from the sheath body 5, the handle 8 of the saw 2 is gripped by one of the palms. Release from the force, the saw blade 3 can be easily extracted from the sheath body 5 to the insertion port 4.

It should be noted that when the saw blade 3 is put in and out of the saw 2, it is important to keep the saw blade 3 out of the sheath body 5 frequently. Even if not pinched, the saw 2 was not always inserted into the distal end portion of the sheath main body 5, that is, the saw blade 3 was inserted to a state slightly before the elastic force from the retaining member 7 did not act. If it is in a state, the sheath body 3 is free and light without any hindrance of the saw blade 3 by elastic force.
It is possible to perform the operation of taking in and out of the device, and it is possible to further improve the work efficiency.

[0010]

[Effects of the Invention] Since the sheath of the present invention has the above-described configuration and operation, it has the following effects. (I). Unless the saw blade is inserted up to the very tip of the sheath body, the elastic force from the retaining member will not be applied, so as in the past,
It is possible to avoid a situation in which the elastic force of the retaining member acts on the saw blade all the time to hinder quick operation, and the operation of inserting and removing the saw blade into and from the sheath body can be performed extremely easily and smoothly. Work efficiency can be improved. (B). The location where the retaining member is attached to the sheath body can be made to face the saw blade not only inside the sheath body that is difficult to attach, but also outside the sheath body that is easy to attach. It can be downsized and suitable for mass production. (C). Pressing and holding by the retaining member is performed in the thickness direction of the saw blade, so that an inconvenient situation in which the saw blade bites into the inside of the sheath body and the saw blade or the sheath body is damaged as in the related art ends. It is prevented naturally. (D). In cases where the saw blade must be frequently taken in and out of the sheath body, the saw blade is not pushed into the distal end of the sheath body, in other words, the saw blade does not receive the elastic force from the retaining member. A light and efficient operation can be achieved by inserting the device up to this level. (E). Conventionally, sawdust and the like easily accumulate inside the sheath body, but the sawdust can be easily discharged from the incision to the outside of the sheath. (F). The saw blade does not rattle or fall out easily inside the sheath, and the saw blade can be taken in and out of the sheath with moderate hardness, and it is possible to avoid injuries etc. and maintain a safe state it can.
