Description

  The present invention relates to a saw sheath for hanging and carrying a saw mainly used for pruning and pruning operations.

  In order to carry the saw, it has been conventionally performed to house the saw in a sheath hanging around the waist or various protective cases. Further, it has been conventionally practiced to provide a locking means so that the saw does not fall off during operation while being accommodated in the sheath and hung. In order to prevent the saw housed in the sheath from falling off, conventionally, it has been common to use a fixed string, a belt, or the like to mainly fix the handle portion to the sheath or protective case. Such a conventional fixing method has a drawback in that workability is poor because it takes time to attach and detach the saw.

The structures of Patent Document 1 and Patent Document 2 have been devised so that the saw accommodated in the sheath can be quickly taken out and the saw does not fall out of the sheath. The invention disclosed in Patent Document 1 forms a handle neck forcing holding portion having elasticity in the sheath body itself, and elastically holds a part of the handle of the saw by this handle neck forcing holding portion. In addition, the invention disclosed in Patent Document 2 prevents the saw from coming out by pressing a retaining member provided on the side surface of the sheath body, specifically, a saw blade inserted into the sheath by a leaf spring. It is a thing.

  The inventions described in Patent Document 1 and Patent Document 2 can freely insert and remove the saw with respect to the sheath, but it is difficult to securely hold the saw accommodated in the sheath. Depending on the person's movement and posture, there was a risk that the saw would fall out carelessly. In view of the drawbacks of the prior art, the present invention prevents the saw housed in the sheath from being inadvertently pulled out, facilitates the removal and storage of the saw, and efficiently performs operations such as pruning. It is an object to provide a saw sheath that can be used.

  In order to achieve the above object, the present invention is attached to the upper outer surface of the sheath body 1 so that the sheath body 1 can be pivoted inward and outward of the sheath body 1 and the distal portion is pivoted inwardly by the spring 10. The biased locking body 3 is arranged. The locking body 3 has a smooth guide surface 3a from the top to the bottom on the inner surface, and a downward claw 11 is formed at the tip of the guide surface 3a. The claw 11 of the locking body 3 is attached to the sheath body 1. The inserted saw 4 is engaged with an engaging step 12 formed on a part of the saw handle 6. As a result, the saw 4 inserted into the sheath body 1 cannot be pulled out because the claw 11 of the locking body 3 engages with the engaging step 12 of the saw handle 6. In order to take out the saw 4, it is possible to remove the saw 4 by pressing the locking body 3 with fingers and releasing the engagement between the claw 11 and the engaging step portion 12.

  The locking body 3 disposed on the upper outer surface portion of the sheath body 1 is provided at the opening end portion of the sheath body 1 and has a structure in which a finger hook portion 3b that is warped toward the outer surface is formed at the proximal end of the locking body 3. In addition, with respect to the inward rotation of the locking body 3, the overturning is greatly larger inward than the position where the claw 11 is engaged with the engagement step portion 12 formed on the saw handle 6. It is preferable to provide a stopper means so as not to occur.

  According to the saw sheath of the present invention, when the saw 4 is accommodated in the sheath body 1, the saw 4 is inserted into the sheath body 1 and the saw handle 6 reaches the claw 11 portion of the locking body 3. When the hook 3 is pushed up by the saw handle 6 itself and the claw 11 reaches the engagement step 12 formed on the saw handle 6, the claw 11 of the lock 3 is engaged with the engagement step 12. In addition, the locked state is maintained by the biasing force of the spring 10, and the saw 4 is prevented from coming out. When the saw 4 is taken out, the locking body 3 is rotated against the urging force of the spring 10 and the like, and the claw 11 of the locking body 3 and the engagement step 12 formed on the saw handle 6 are engaged. By releasing, it can be taken out freely.

  According to the second aspect of the present invention, when the engagement between the claw 11 of the locking body 3 and the engagement step portion 12 formed on the saw handle 6 is released in order to take out the saw 4, it is hung on the saw handle 6. Since the rotation operation of the locking body 3 can be performed with a finger of the hand, the handling is easy. According to the invention described in claim 3, when the saw 4 is taken out, the locking body 3 does not rotate more than necessary, and the saw 4 can be easily inserted into the sheath body 1. Have real benefits that can.

  Hereinafter, preferred embodiments of a saw sheath according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view of only an upper portion of a saw sheath according to the present invention.

  The saw sheath of the illustrated embodiment includes a flat tubular sheath body 1 into which the saw blade plate 5 of the saw 4 can be inserted, and a suspension piece for hanging the sheath body 1 on an operator's waist belt or the like. 2 and a locking body 3 for locking the saw 4 inserted in the sheath body 1. The sheath body 1 has a tapered shape in accordance with the shape of the saw blade plate 5 of the saw 4 to be accommodated, and a part of the saw handle 6 of the saw 4 enters into the opening at the upper end. That is, the width of the sheath body 1 that is a flat tube is tapered and the thickness thereof is also increased upward, and the tip of the saw handle is inserted so that only the tip of the saw handle 6 enters the upper end. Part 7 is formed. A locking body 3 for preventing the saw 4 from coming out is disposed on the outer surface of the upper portion of the sheath body 1 of the saw handle tip insertion portion 7.

  In order to arrange the locking body 3 on the upper outer surface of the sheath body 1, a locking body accommodating portion 8 is formed. The locking body accommodating portion 8 is formed in a substantially trapezoidal shape by erecting ribs 9, 9 on both the left and right sides, and the locking body 3 having a substantially trapezoidal flat plate shape is arranged in a manner of fitting inwardly. The locking body accommodating portion 8 is formed by cutting a part of the bottom wall 8a to form a window hole 8b, and by supporting the locking body 3 on the ribs 9 and 9 on both the left and right sides, 3 is rotatable in the inner and outer directions of the sheath body 1 so that at least the distal end portion of the locking body 3 can be projected and retracted inside the sheath body 1.

  In order to arrange the locking body 3 in the locking body housing portion 8 so as to be rotatable, in the illustrated embodiment, recesses 13 and 13 are formed in the left and right side walls and the bottom wall 8a of the locking body housing portion 8. At the same time, as shown in FIG. 4, short cylindrical projections 14, 14 that fit into the recess 13 are formed on the back surface of the locking body 3, and the projection 14 is fitted into the recess 13. The stop body 3 is rotatable. That is, the locking body 3 is pivotally attached. This attachment structure may be another pivoting structure, for example, one that is pivoted through another shaft.

  The overall planar shape of the locking body 3 is the same as the shape of the locking body housing portion 8 formed in the sheath body 1, but as shown in FIG. The protruding portion 15 is formed in a shape along the shape of the window hole 8b formed in the body accommodating portion 8. On the back surface of the locking body 3, portions other than the protrusions 15 and the protrusions 14 are formed on a flat surface. Further, a spring receiving portion 16 is formed as a recess at a position above the protrusion 14 on the back surface of the locking body 3, and the locking body 3 is also formed on the bottom wall 8 a of the locking body housing portion 8. A spring receiving portion 17 which is a recess corresponding to the spring receiving portion 16 is formed, and a coiled spring 10 is mounted between the spring receiving portions 16 and 17 as shown in FIG. As a result, the locking body 3 is assembled in a state in which the distal portion is biased to rotate inward of the sheath body 1. The spring that urges the locking body 3 inward can be replaced by any spring means other than the coiled spring 10.

  With the above-described structure, the locking body 3 is in a state in which the distal portion is urged to rotate toward the inside of the sheath body 1, and the protruding portion 15 is the locking body housing portion. 8 is protruded into the inside of the sheath main body 1 from the window hole 8b, and a flat portion other than the protruding portion 15 is set in contact with the bottom wall 8a of the engaging body accommodating portion 8. That is, the contact between the surface of the locking body 3 other than the protruding portion and the bottom wall 8a of the locking body housing portion 8 serves as stopper means, thereby preventing the locking body 3 from over-rotating.

The projecting portion 15 projecting into the inside of the sheath body 1 is formed so that the tip projects most greatly and linearly decreases toward the base. That is, the tip of the protrusion 15 functions as the claw 11, and the linear surface following the claw 11 becomes the guide surface 3a. In the illustrated embodiment, since the projecting portion 15 is formed in a rib shape branched in a trifurcated shape, the upper surface of the rib shape is the guide surface 3a. However, the projecting portion 15 may not be a rib shape, but may bulge entirely in a trapezoidal shape, and the entire upper surface thereof may be the guide surface 3a.
In addition, a finger hook portion 3b that warps outward is formed at the upper end of the locking body 3.

  The shape of the saw 4 accommodated in the sheath body 1 described above is such that the saw blade plate 5 can be inserted into the sheath body 1 and the tip of the saw handle 6 can be inserted into the saw handle tip insertion portion 7 of the sheath body. If there is, it will not be specifically limited. Although the shape of the saw 4 inserted into the sheath body 1 is arbitrary, a specific example of the saw 4 is shown in FIG. The saw 4 shown in FIG. 7 is provided with a metal saw handle 6 formed by aluminum die casting or the like. The neck portion 6a exposes the metal, and the gripping portion 6b is subjected to a non-slip rubber process. Yes. At least the neck portion 6a where the metal is exposed is shaped and sized to be inserted into the sawtooth tip insertion portion 7 of the sheath body 1. An engaging step portion 12 as shown in FIG. 8 is formed at the side surface tip of the saw handle 6, that is, the side surface portion of the neck portion 6a tip. The front side of the engagement step portion 12 is continuous with the front end surface of the saw handle 6 with a relatively large rounded surface. The height of the engagement step portion 12 does not need to be particularly high, and it is sufficient that it should be 1 to 2 millimeters at the highest portion in the center and converge at a height of 0 toward the upper and lower ends in the drawing. And can look good. By making the saw handle 6 made of metal and forming the engagement step portion 12 in this metal portion, the engagement step portion 12 is less worn and a long and reliable operation can be maintained.

  When the saw 4 as shown in FIG. 7 is inserted from the upper end opening of the saw sheath according to the present invention shown in FIG. 1 and the saw handle 6 is inserted into the saw handle tip insertion portion 7 of the sheath body 1, First, the tip portion of the saw handle 6 comes into contact with the guide surface 3a on the back surface of the locking body 3, and as the saw 4 is inserted, the locking body 3 resists the elasticity of the spring 10, and the outer side indicated by a dotted line in FIG. When the position of the engaging step 12 formed on the saw handle 6 reaches the position of the claw 11 of the locking body 3, the locking body 3 is moved to the inside by the elasticity of the spring 10. 2, the claw 11 of the locking body 3 engages with the engaging step portion 12 of the saw handle 6 as shown in FIG. 2. Therefore, the saw 4 is held in a state where it cannot be pulled out. At this time, since the tip of the saw handle 6 is formed with a relatively large rounded surface, the locking body 3 can be smoothly pushed outward. Moreover, since the back end of the saw handle tip insertion portion 7 of the sheath body 1 is matched to the tip shape of the saw handle 6, the inserted saw 4 is stably held. At this time, as shown in FIG. 9, the grip 6 a of the saw handle 6 protrudes from the upper end of the sheath body 1 with the saw 4 inserted into the sheath body 1.

As shown in FIGS. 2 and 9, in order to take out the saw 4 held by the sheath body 1, the upper end portion of the locking body 3 is pressed with fingers, and the locking body 3 as shown by the dotted line in FIG. Rotate the tip of to the outside. When the locking body 3 rotates outward, the engagement between the claw 11 and the engaging step 12 of the saw handle 6 at the tip of the locking body 3 is released, and the saw 4 can be taken out freely. That is, the locking body is pressed by pressing the upper end portion of the locking body 3, for example, the finger hooking portion 3b that is curled outward, with the finger of the hand holding the gripping portion 6a of the saw handle 6 protruding from the sheath body 1. 3 is disengaged from the engaging step 12 of the saw handle 6, and the saw 4 can be easily extracted.
Thus, in the case of the saw sheath according to the present invention, when the saw 4 is accommodated in the sheath body 1, the engaging step portion 12 formed on the saw handle 6 and the claw 11 of the locking body 3 can be formed by simply inserting the saw. In addition to being able to engage, when pulling out the saw 4, it can be easily attached and detached by a series of actions of pulling out while pressing the upper end of the locking body 3 with the finger of the hand holding the saw handle 6. It is.
