Description

Detailed description of the invention

The present invention relates to a sheath for a saw having a structure for safely and easily holding the saw in a sheath for housing the saw and preventing the saw from falling off.

In the conventional saw sheath, the saw is provided inside the sheath by providing an elastic spring or the like that presses the saw to hold it inside the sheath, or by firmly engaging the holding portion of the saw with the insertion portion of the sheath. Was holding on to. If a spring or the like having an elastic force is used, it is necessary to provide the sheath or the saw holding portion, but in this case, the cost of parts is increased, and at the same time, an extra step and time for mounting the parts are required. Has become more complicated, resulting in higher production costs.

In the case where the engagement is hardened, a delicate adjustment is required for the engagement between the engagement portion of the saw and the insertion portion of the sheath. Moreover, as the saw is repeatedly inserted and removed, the engagement portion becomes loose and the saw cannot be held in the sheath, and the saw falls off the sheath, which is very dangerous.

As a simple measure to prevent the saw from falling off, there is a method of hanging a loop-shaped leather / vinyl belt around the saw holder, but this loop-shaped belt may get caught on the blade of the saw when inserting or removing the saw. Many of them become obstacles and reduce work efficiency.

Issues that the device is trying to solve

When an extra part such as an elastic spring is provided to hold the saw in the sheath, the structure becomes complicated and the manufacturing cost increases. Further, when the saw is held on the sheath by engagement, it is necessary to finely adjust the pressing force without being too stiff or too loose, but such fine adjustment also increases the production cost. In addition, there is a possibility that the saw may come loose from the sheath due to the long-time insertion / removal of the saw, and the operator may be injured. Even in the case of holding with a loop-shaped belt or the like, the saw blade is caught on the belt when the saw is taken in and out, which hinders the work.

Means for solving the problem

The present invention has been made to eliminate these drawbacks.A conventional sheath has a structure in which a wall on one side is removed, an opening is provided, and a parallel translation is inserted from the back of the saw blade into the opening on the side to insert. A raised portion is provided on one wall surface inside the sheath, and the saw blade rides on the raised portion to generate the elastic force of the saw blade, and the saw is stored and held in the sheath.

Also, by providing a projection on the inner surface of the sheath, the saw is prevented from jumping out of the sheath. When removing the saw from the sheath, the handle of the saw is released from the protruding portion by pressing the saw handle in the direction opposite to the restoring force of the saw blade, and then is slid laterally from the side surface of the sheath and removed from the sheath.
A guide plate for guiding the saw blade into the sheath is provided around the saw blade insertion port of the sheath. This allows a long saw blade to be easily inserted into the sheath. Since it is not necessary to use an elastic part such as a spring when manufacturing the sheath, the sheath can be easily manufactured and the production cost can be kept low.

As shown in FIG. 1, the wall of one side of the sheath body 1 is removed and opened like 1a so that the inside of the sheath body can be looked into. Thereby, the saw blade 4 shown in FIG. 2 can be inserted from the portion 1a. As shown in the front view 6 of the sheath, the portion 1a has a shape protruding from the upper surface of the sheath. When inserting the saw into the sheath, a saw blade is placed on the protruding portion so that the saw can be inserted into the sheath. Plays the role of guiding.

A raised portion 1b is provided on the inner bottom surface of the sheath body 1. As shown in FIG. 2, the saw blade 4 is slid into the sheath body, so that the saw blade 4 rides temporarily on this raised portion. Since the saw blade has elasticity, the saw blade is passed under the portion 1c while being pressed against the bottom surface side of the sheath (see FIG. 5), and is received by the sheath body. When the saw is completely received in the sheath (see FIG. 7), the saw blade is pressed against the upper surface of the sheath 1 by the elasticity of the saw blade (see FIG. 4), and the saw is pushed into the sheath by the projection 1c. Is held.

An embodiment of the present invention will be described with reference to FIG. The sheath body 1 of FIG. 1 is provided with an open surface 1a from which one side wall is removed. A raised portion 1b is provided on the bottom surface inside the sheath body 1. A projection 1c is provided on the upper surface of the sheath to prevent the saw blade received inside the sheath from sliding in the lateral direction. A belt loop 2 is provided on the sheath body so that the sheath can be attached to the waist portion of the worker by passing through the belt of the worker.

The effect of the invention

The saw blade can be easily guided and inserted into the sheath simply by aligning the tip of the saw blade 4 with the guide plate shown in FIG. In addition, since the elasticity of the saw blade 4 is used, other components such as a spring need not be mounted. This makes it possible to produce a sheath that is easy to assemble and that has a reduced cost.

It is a perspective view of a sheath. It is a figure which is going to insert the saw 3 in a sheath. The state where the saw was received in the sheath is shown. It is a side view in the state where saw 3 was received in sheath main part 1. FIG. 2 illustrates a moment when the protruding portion 1 is passed through when the saw 3 is taken out from the sheath body 1 or when the saw 3 is inserted into the sheath body 1. It is a front view of a sheath. It is a front view at the time of putting a saw in a sheath.
