However, the saw sheath described in Patent Document 1 can exert an effect when guiding the insertion of the saw body (1) into the sheath (6), but the insertion opening (3) for inserting the saw body is wide. Construction, because the saw body (1) is easy to insert, the inserted saw body (1) is also easy to fall out, especially because of the hard The roller part (4) produces a reverse guide, which is prone to accidents that are unintentional.

Further, since a pair of rigid roller members (4) are arranged in a rough manner near the entrance, the roughness thereof causes a problem that the direction of the blade tip surface inserted into the sheath (6) cannot be guided, and therefore, the saw body ( 1) The blade tip surface is tilted and rotated in the flat surface of the sheath (6). As a result, the blade tip surface is damaged by the inner wall of the sheath or is stuck in the inner wall, leaving it impossible to smooth. Inserted question.

Further, in the case of the sheath of a saw or the like disclosed in Patent Document 2, since the roller (3) is provided on one side of the sheath body (1), the blade portion (4) of the saw moves on the roller. This effect prevents the sheath from being damaged by the saw blade, but does not achieve the purpose of smoothly inserting the saw from the inlet of the sheath body (1), and does not exhibit such an effect.

Further, in the case of the sheath of a saw or the like disclosed in Patent Document 3, it is possible to prevent the saw inserted into the sheath (1) from being pulled out from the sheath, but the elastic fit of the saw handle (4) and the sheath (1) The combination is not based on the combination with the roller, but is a concave-convex fitting which is simply formed by the elasticity of the thin resin film. Although it can be temporarily used after being removed from the package, the design is actually a packaging container; in addition, it is easily cut by the saw blade, and the durability problem that can withstand long-term repeated use occurs.

Further, in the case of the sheath of the saw or the like disclosed in the above Patent Document 4, since the grip insertion preventing member (15) must be formed as an upright vertical column on the back surface of the first guide roller (11a), the sheath member (10) is made The type is very complicated and becomes a difficult problem. Further, in the case where the columnar grip is inserted into the preventing member (15), there is only one back surface of the first guide roller (11a) mounted on one side, the saw grip (32) and the grip insertion preventing member ( 15) The docking position is on one side and there is only one place, and there is a problem that the shaking is unstable. Therefore, the necessity of the pair of grip insertion preventing members (15) to be attached to both sides is increased, and the disadvantage is that such a configuration makes the formation of the sheath member (10) more complicated and becomes a difficult design. .

Here, the present invention solves various problems of the foregoing prior art, and provides that the insertion of the saw at the entrance of the sheath becomes easy, and the inserted saw is not easily ejected or unstable in the sheath. Inserting the blade edge of the saw blade inserted into the sheath into the depth smoothly, thereby sufficiently reducing the saw sheath for cutting the inner wall of the saw blade in the sheath; providing the storage structure of the saw sheath and the retractable saw This is the subject of the present invention.

In order to achieve the above-described object, the saw sheath of the present invention includes a flat sheath member and a sheath body that is continuously flattened; the saw blade is inserted from the tip of the saw blade through the sheath member. a sheath sheath of the sheath body; the sheath member configured to have a wide opening and narrowed to a depth, and a guide blade is provided on the left and right sides of the widthwise direction of the inlet of the sheath member a pair of guide rollers that enter the opening of the sheath member; and a grip insert preventing section that blocks the insertion of the upper portion of the sheath member; Further, the pair of guide rollers are inserted into the space for the grip insertion preventing member, and the pair of guide rollers are elastically deformable while being subjected to the front end of the saw grip grip member for elastic engagement. Elastic grip-fitting space; such a configuration is taken as the first feature.

Further, in the saw sheath of the present invention, in addition to the first feature described above, the grip insertion preventing member is formed by using a part of the inner wall of the opening of the sheath member. Two features.

Further, in the saw sheath of the present invention, in addition to the first and second features described above, the inner wall of the opening of the sheath member is formed as a guide inclined guide surface for the sheath member The direction of the saw blade inside the opening insertion opening coincides with the flat direction of the sheath hole of the sheath body; and a part of the aforementioned inclined guide surface is formed as a grip insertion preventing member, and such a configuration is a third feature.

Further, the saw sheath and the saw storage structure according to the present invention are the saw sheath and the saw storage structure according to any one of the first to third aspects; the saw is designed at a front end of the saw grip a bulging member that passes through the aforementioned sheath sheath guide roller during elastic deformation; when the saw is inserted into the saw sheath, the bulging member of the saw grip is blocked at the crossing position of the sheath guide roller; the front end of the saw grip is at the saw While the grip insertion preventing member of the sheath is blocked, it is held in the space for elastic engagement of the grip; when the saw is pulled out from the sheath, the saw grip held in the space for elastic engagement of the grip is held. The bulging member of the front end is slid over the pull-out direction with respect to the saw sheath guide roller, and the saw is pulled out by the saw sheath; such a configuration is a feature of the present invention.

According to the saw sheath according to the first aspect of the patent application, the saw sheath is a flat sheath member and a sheath body which is continuously flattened by a sheath, and the saw blade is inserted into the sheath portion from the sheath member toward the rear. The sheath body gradually enters. Since the sheath member has a wide inlet and a pair of guide rollers are disposed on both sides in the lateral direction, the tip end of the saw blade is easily guided from the wider inlet of the sheath member by the aforementioned guide roller. Inside the opening, it is guided into the sheath body.

Moreover, according to the saw sheath sheathed in the first item of the patent application scope, due to the opening of the sheath member The grip insertion preventing member and the saw grip are disposed in the mouth, that is, the upper portion of the grip of the saw can be prevented from being inserted into the saw sheath at all times, and the tip end of the saw blade can be prevented from hitting the bottom of the saw sheath.

In particular, since the space from the pair of guide rollers at the inlet of the sheath member to the grip in the opening of the sheath member is inserted into the space for preventing the member, the space for elastically fitting the grip is subjected to elastic deformation with respect to the guide roller. The front end member of the saw grip is used to hold the fitting; the saw front end member that passes through the guide roller and stops at the grip insertion preventing member when the saw is inserted into the sheath sheath is elastically fitted to the grip The space is fitted and held in this state in a state of being sandwiched between the pair of guide rollers and the grip insertion preventing member.

On the other hand, when the saw is pulled out from the saw sheath, the saw grip is gripped, and the front end member of the saw grip held by the elastic engagement space of the grip is pulled in the pull-out direction, with respect to the guide roller The elastic deformation crosses the past, so the fitting of the front end member of the saw grip is released, and the saw is pulled out of the outer sheath of the saw.

Of course, regardless of whether the saw is inserted into the sheath or the sheath is pulled out, the insertion and extraction of the elastic deformation of the saw grip are easier to perform because the roller of the guide roller rotates.

Therefore, according to the invention described in the first paragraph of the patent application, the insertion of the saw at the entrance of the sheath is easy, and there is no possibility that the inserted saw is likely to fall out or be damaged in the sheath. Furthermore, since the blade edge of the saw blade can be smoothly guided into the sheath sheath, the saw blade can be sufficiently reduced in the case of cutting the inner wall of the sheath.

Further, in addition to the effect of the structure described in the first item of the above-mentioned patent application, the grip insertion preventing member according to the second aspect of the patent application is added. It is made by using a part of the inner wall of the opening of the sheath member, so that the grip insertion preventing member is not required to be attached with other components, as long as the inner wall shape of the opening of the sheath member is considered, Made. Therefore, the number of parts and the combination of man-hours can be reduced.

Further, in addition to the effect of the structure described in the first or second aspect of the aforementioned patent scope, in addition to the opening of the sheath member, the saw sheath according to the third aspect of the patent application is added. The inner inner wall is formed to guide the inclined guide surface from the inlet of the sheath member into the opening in the opening so as to conform to the flat direction of the sheath body, and a part of the inclined guiding surface is made into a grip Because of this configuration, the blade edge of the saw blade inserted into the opening of the sheath member is guided at the inclined guide surface to correct the direction of the flat blade tip and the sheath hole of the sheath body The flat direction is the same and it is easy to operate. Therefore, the blade tip can be guided and inserted smoothly from the sheath opening member toward the sheath body without any trouble.

Further, a part of the inclined guiding surface is configured as a grip insertion preventing member, so that the cutting edge direction can be corrected to the direction of the sheath hole at one position of the inclined guiding surface. This causes the front end of the saw grip that inserts the traction saw blade into the opening of the sheath member.

Further, the storage structure of the saw sheath and the saw according to the fourth aspect of the invention is the storage structure of the saw sheath and the saw described in any one of the first to third features. before The saw is designed to have a bulging member that passes through the saw sheath guide roller when elastically deformed at the front end of the saw grip; when the saw is inserted into the saw sheath, the bulging member of the saw grip is on the sheath guide roller The traversing position is blocked; the front end of the saw grip is held in the elastic engagement space of the grip while the grip insertion preventing member of the saw guard is blocked; and the saw is retained from the sheath when the saw is pulled out The bulging member at the front end of the saw grip in the space for elastically fitting the grip is slid in the direction of pulling out with respect to the saw sheath guide roller, and the saw is pulled out by the saw sheath; Because it is such a structure, the saw blade is quickly inserted from the sheath opening into the sheath body with respect to the sheath sheath, and is not hindered, and can be smoothly guided to the deepest point. Therefore, it is possible to sufficiently reduce the situation in which the saw blade cuts the inner wall of the sheath.

Moreover, when the saw grip enters the opening of the sheath member of the saw sheath, the elastic fitting space is surely held by the grip, so that the inserted saw does not unexpectedly pull out the saw sheath It will not cause damage inside the sheath.

Of course, when the saw is pulled out from the saw sheath, the front end of the saw grip is elastically pulled out along with the rotation of the guide roller, so that it can be sufficiently smoothly pulled out.

The saw sheath associated with this embodiment will be described with reference to the following drawings.

First, referring to Figs. 1(A) to (D), the saw sheath 1 is made of the sheath member 10 and the sheath body 20. At the sheath member 10. A hanging member 30 that can be freely attached and detached is installed.

At the saw sheath 1, the saw 2 can be inserted freely into and out.

According to the needs of the user, the saw 2 can be pulled out from the saw sheath 1 or the saw sheath 1 can be inserted at the end of the work.

The user can use the hanging member 30 to wear the saw sheath 1 to the waist or the like.

Referring to Fig. 2 (A) to (C), the sheath member 10 and the sheath body 20 of the saw sheath 1 are formed into a flat cylindrical body. The sheath member 10 and the sheath body 20 may be connected together to form an integrally formed structure, or may be separately fabricated and combined to serve as the saw sheath 1.

The sheath member 10 is constructed such that its opening amplitude 'is broad at the inlet 11 and narrower toward the depth in the opening.

The inlet 11 of the sheath member 10 is configured as a flat opening, and a pair of guide rollers 12 that are freely rotatable are mounted on the left and right sides of the lateral direction "longitudinal direction of the inlet" of the flat inlet 11. The pair of guide rollers 12 whose rotation axis is perpendicular to the lateral direction "longitudinal direction" of the inlet 11 "the short side direction of the inlet" can complete the saw blade tip 41a of the saw 2 to be inserted. Referring to Figure 3 (A), it is smoothly guided into the inlet 11 of the sheath member 10.

Referring to FIG. 3 again, the saw 2 is provided with a saw blade 41, a saw blade tip 41a, and a saw grip 42.

A bulging member 43 is provided at the front end 42a of the saw grip. The aforementioned saw grip 42, including the bulging member 43, may be made of elastic rubber or plastic, or may be made of other materials; however, at least the bulging member 43 is constructed of an elastically deformable material. The saw grip 42 and the bulging member 43 of the front end 42a thereof are integrally formed, but are not necessarily limited thereto.

At the sheath member 10 of the saw sheath 1 described above, a blade end receiving table 13 is provided for receiving the blade edge 41a of the saw 2 and guiding it to the side of the inlet 11. The blade tip receiving platform 13 is formed by the aforementioned The mouth 11 starts and is made to extend out without a height difference. When the saw 2 is inserted into the saw sheath 1, the blade tip 41a of the saw 2 is first received by the blade end receiving table 13, and is guided while the blade end receiving table 13 is moved to reach the guide roller 12 by the guide roller. 12 is quickly introduced into the entrance 11.

At the front end of the blade end receiving table 13, a hanging member 30 is attached to the side of the back surface.

The hanging member 30 is constituted by the fitting claw member 31 of the blade edge receiving table 13 and the hanging strap member 32.

The sheath body 20 is a flat and elongated tubular body having a flat sheath hole 21 (see FIG. 4 to FIG. 7) inside.

The sheath hole 21 is a structure in which the inlet 11 of the sheath member 10 and the inlet are continuously smooth.

The end of the sheath body 20 can be in a closed state in addition to the open state. The length and width of the sheath body 20, the length of the longitudinal direction of the flat cut surface, and the thickness of the short length of the flat cut surface are as short as possible, short in width, and thick in the range of the slidable cutting edge. Thin and light weight is the most ideal.

When the sheath body 20 and the sheath member 10 are integrally molded, it is preferable to use a synthetic resin. When the sheath body 20 and the sheath member 10 are made of different materials, the sheath body 20 is preferably formed. In addition to the synthetic resin, a light metal such as aluminum or the like may be used.

Referring to FIGS. 2(D) and 5, the inclined guide surface 14, the grip insertion preventing member 15, and the grip elastic fitting space 16 are provided in the opening of the inlet 11 of the sheath member 10.

The inclined guide surface 14 is designed such that the direction of the blade edge 41a of the saw blade 41 inserted from the inlet 11 of the sheath member 10 coincides with the flat direction of the sheath hole 21 of the sheath body 20.

The inclined guide surface 14 is formed as a slanting surface of a considerable length which is inclined by the rearward position of the guide roller 12 of the inlet 11 of the sheath member 10 to reach the sheath hole 21 of the sheath body 20 The length of the long side of the flat sheath hole 21.

In the present embodiment, the inclined guide surface 14 is attached to one side in the longitudinal direction of the flat opening of the sheath member 10, but may be attached to the opposite sides in the longitudinal direction.

The blade edge 41a of the saw blade 41 of the pair of guide rollers 12 is guided by the inclined guide surface 14, and the direction of the surface of the blade edge 41a is corrected to match the flat direction of the sheath hole 21. Enter the sheath hole 21.

The grip insertion preventing member 15 is designed such that the saw grip 42 that enters the opening from the inlet 11 of the sheath member 10 cannot penetrate to a specific position or more.

The grip insertion preventing member 15, more specifically, may be formed by using a part of the inner wall in the opening of the sheath member 10; that is, by inserting the grip with the grip at the inner wall in the opening of the sheath member 10. It is possible to prevent the same projection of the member 15, or to insert the prevention member 15 by the grip, and to block the front end 42a of the saw grip, and it is not possible to insert it.

Actually, a part of the inclined guide surface 14 formed in the opening of the sheath member 10 can be used as the grip insertion preventing member 15. Due to the presence of the inclined guiding surface 14, the diameter in the opening of the sheath member 10 gradually becomes smaller toward the sheath hole 21, and the diameter in the opening is smaller than the outer diameter of the front end 42a of the saw grip. The front end 42a of the saw grip is inserted, so that a part of the inclined guide surface 14 formed by the smaller diameter of the opening of the sheath member 10 smaller than the outer shape of the front end 42a of the saw grip becomes the grip insertion preventing member. 15.

The grip elastic fitting space 16 (see FIG. 4) is a space between the guide roller 12 and the grip insertion preventing member 15 in the opening of the sheath member 10. In the grip elastic fitting space 16, the saw grip front end 42a abuts the grip insertion preventing member 15, and the bulging member 43 of the saw grip 42 is inserted while the guide roller 12 is elastically deformed. Go in. In other words, the saw grip front end 42a is inserted into the grip elastic fitting space 16 so as to be caught between the grip insertion preventing member 15 and the guide roller 12, and is held in a fitted state. The bulging member 43 which is passed through when the guide roller 12 is elastically deformed is elastically fitted in a state in which it is stopped at a position just before, and is in contact with a part of the guide roller 12, and is maintained in this state. Therefore, the saw grip front end 42a is maintained in a stable state in the grip elastic fitting space 16.

In other words, the grip elastic fitting space 16 is a space in which the front end 42a of the saw grip is elastically fitted.

That is, when the saw 2 is inserted into the sheath member 10, the bulging member 43 is inserted into the grip preventing member 15 at a position just past the guide roller 12, and the portion of the front end 42a of the saw holder is blocked from being inserted. The saw grip 42 remains resiliently fitted.

On the other hand, when the saw 2 is pulled out from the saw sheath 1 and pulled out by the grip grip 42, the bulging member 43 in the grip elastic fitting space 16 is elastically deformed by the guide roller 12, thereby The saw grip end 42a is disengaged from the grip elastic fitting space 16, and the saw 2 is pulled out from the sheath member 10.

Please refer to Fig. 4 to Fig. 7 to explain the effect of inserting the saw 2 with respect to the saw sheath 1.

Next, the saw 2 shown in Fig. 3 is inserted into the empty saw sheath 1 shown in Fig. 2. As the user inserts, first, as shown in FIG. 5, the blade edge 41a of the saw 2 contacts the blade end receiving table 13, and slides on the blade end receiving table 13 toward the inlet 11. Then, a pair of guide rollers 12, 12 disposed on the left and right sides in the lateral direction of the inlet 11 are inserted between the blade tips 41a, and the saw blade 41 contacts either of the pair of guide rollers 12, 12 against the guide roller 12. Quickly guide to the inside. At this time, since the guide roller 12 is kept free to rotate, the saw blade 41 faces the insertion direction of the saw sheath 1 and contacts the guide roller 12, and accordingly, the guide roller 12 rotates, and the saw blade 41 smoothly enters the inlet 11 The inside.

The gap between the pair of guide rollers 12, 12 is designed to be the same as or slightly wider than the length of the longitudinal direction "longitudinal direction" of the sheath hole 21 of the sheath body 20, so the saw 2 is no matter what The angle is guided by the guide roller 12, and the blade edge 41a can be surely introduced into the gap of the transverse direction "longitudinal direction" of the sheath hole 21 of the sheath body 20.

Once the blade tip 41a of the saw 2 reaches the inclined guiding surface 14, the blade tip 41a guides the tilting The oblique guide surface 14 faces the sheath hole 21 of the sheath body 20, and at this time, the length of the longitudinal direction "longitudinal direction" of the sheath hole 21 is a direction perpendicular to the "short side direction", which is smaller than the sheath member 10 described above. The length of the short side direction of the inlet 11 "that is, flatter than the inlet 11". Therefore, when the blade edge 41a and the saw blade 41 connected thereto are guided on the inclined guide surface 14, the direction thereof coincides with the direction of the flat sheath hole 21.

Referring to Figure 6, once the saw blade 41 of the saw 2 is deeply inserted into the sheath body 20, the saw front end 42a naturally reaches the inlet 11 of the sheath member 10, and the bulging member 43 disposed at the front end 42a of the saw grip arrives. A pair of guide rollers 12. At this time, the front end 42a of the saw grip is temporarily blocked by the guide roller 12 due to the presence of the bulging member 43.

When the front end 42a of the saw grip is temporarily blocked by the pair of guide rollers 12, the bulging member 43 is elastically deformed while passing over the guide roller 12 while being urged by the user in the direction in which the saw is inserted. At this time, since the guide roller 12 rotates, the traverse of the bulging member 43 proceeds smoothly.

Referring to Fig. 7, the bulging member 43 has just passed through the guide roller 12. At this position, because of the midway position of the inclined guide surface 14, a portion of the inclined surface is formed by the grip insertion preventing member 15, the aforementioned saw The insertion of the upper portion of the front end 42a of the grip is prevented. Therefore, the grip front end 42a is in the grip elastic fitting space 16 in a space in which the grip insertion preventing member 15 and the pair of guide rollers 12, 12 are held in a fitted state. At this time, the rear end of the bulging member 43 is in contact with the guide roller 12 in an elastically deformed state, so that the front end 42a of the grip The grip elastic fitting space 16 is elastically fitted and placed in an immovable state, that is, the saw 2 is held in a stable state.

Next, the operation when the saw 2 is pulled out from the saw sheath 1 will be described.

In this case, as shown in Fig. 7, that is, the saw 2 "saw blade 41" is housed in the saw sheath 1, and the user holds the saw grip 42 and pulls it in the direction in which the saw sheath 1 is pulled out. Once this is done, by pulling out, the bulging member 43 of the saw grip 42 is elastically deformed and passes through the guide roller 12 in a direction in which it is pulled out. At this time, since the guide roller 12 rotates, the traverse of the bulging member 43 can be smoothly performed, and therefore, the pulling out of the saw 2 can be easily performed.
