Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention is applied to, for example, mountain climbing, mountain vegetable picking,
The present invention relates to a sheath for a knife carried on hiking, diving, and the like.

[0002]

2. Description of the Related Art Conventionally, as a knife sheath of this type, as shown in, for example, Japanese Utility Model Laid-Open Publication No. Sho 57-94469, a blade member is pressed by a spring material in a state where a knife is inserted into a storage portion. There is known one in which the knife is prevented from coming off by pressing.

[0003]

However, in the case of this conventional structure, it is possible to prevent the knife from being pulled out to some extent by the pressing action of the spring material. When a large external force is applied, it may come out unexpectedly, and there is a disadvantage that a very dangerous state may be caused.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve such inconvenience, and the gist of the present invention is to store a knife including a blade, a handle and a flange for climbing. A sheath portion in which a blade portion can be inserted in the sheath body, a locking projection that the flange portion can climb over at the end of the blade portion insertion at the open end of the sheath portion of the sheath body, and the sheath body. A spring member capable of elastically pressing the blade portion toward the locking projection at the opening end of the collar is further provided. A knife sheath characterized by comprising a rotary knob capable of holding or releasing the overriding locked state.

[0005]

The rotary knob is turned to the released state, and the blade is inserted into the sheath body. When the blade is completely inserted, the flange goes over the locking projection and the spring member locks the blade. When the rotary knob is rotated in this over-pressed state, the rotary knob can be brought into contact with the flange portion, and the over-locking state is restricted.

[0006]

1 to 8 show an embodiment of the present invention. Reference numeral 1 denotes a knife, which comprises a blade 2, a handle 3 and a flange 4. FIG.

Reference numeral 5 denotes a sheath body, which is formed of a synthetic resin and has a housing portion 6 in which the blade portion 2 can be inserted, and a waist abutment portion for hanging the opening portion 7 of the housing portion 6 on a belt or the like. 8 and a belt suspension 9 are formed.

Reference numeral 10 denotes a locking projection which is formed on one side of the opening end 7 so that the inner space of the storage section 6 is closed when the blade 2 is completely inserted. Are formed so as to be able to get over the locking projection 10.

Reference numeral 11 denotes a spring member. In this case, a leaf spring is used. The spring member is provided on the other side of the open end 7 of the sheath body 5 so as to resiliently press the blade 2 toward the locking projection 10. Is configured.

Reference numeral 12 denotes a rotary knob. In this case, a rotary knob 12b is formed so as to project from the center of a substantially rectangular knob-shaped plate 12a. Is rotatably inserted through the sheath wall 5a of the first member, and the spring member 11 is connected to the plate portion 11a.
11b, the elastic tongue 11c is formed in one of the plate portions 11a, three holes 11d are formed in the plate portion 11b, and a fixing screw 13 is passed through the hole 11d to stop. Arrival screw 1
3 is screwed onto three boss portions 5b projecting from the inner surface of the sheath wall 5a to fix the plate portion 11a.
A keyhole-shaped through-hole 14 is formed by connecting a locking hole 14a and a large-diameter hole 14b that can be locked to the annular locking groove 12d formed on the inner surface protruding portion 12c of the sheath wall of the rotating shaft portion 12b. The blade portion 2 is formed to resiliently press the blade portion 2 by the plate portion 11b. Therefore, the spring member 12 also serves to attach the rotary knob 12, and the bottom surface of the knob plate portion 12a of the rotary knob 12 is a flange. Part 4
Is formed on a contact surface 12e that can contact the
When the rotary knob 12 is rotated to a position facing the flange 4, the above-mentioned locking state of the flange over the locking projection 10 is held and regulated. Further, as shown in FIG. When the rotary knob 12 is rotated to a position where the rotary knob 12 does not face, the overriding locked state is released.

In this case, a concave seat 5c is formed on the sheath wall 5a, and the rotary knob 12 is disposed on the seat 5c.
A stopper projection 15 is formed on the peripheral surface of the seat 5c. The stopper projection 15 regulates the rotation range of the rotary knob 12 to 90 degrees in the normal and reverse directions, and the detent projection 16 is formed on the seat 5c.
And two positioning recesses 17 are formed on the bottom surface of the knob plate portion 12a at intervals of 90 degrees, and the elastic tongue pieces 11c are formed.
The detent projection 16 and the positioning recess 17 can be fitted and detached by the elastic action of.

Since this embodiment has the above configuration, FIG.
As shown in FIGS. 4 and 5, the rotary knob 12 is rotated to the released state, and the blade 2 of the knife 1 is inserted into the storage section 6 in this state. Is pressed against the spring member 11, and the knife 1 is further inserted while the knife 1 is pressed, so that the flange portion 4 gets over the locking protrusion 10. When the knife 1 is released, the blade portion 2 is pressed toward the locking projection 10 by the spring member 11, and the rear surface of the flange 4 is locked by the locking projection 10.

In this state, as shown in FIGS. 2, 3, 6, and 7, when the rotary knob 12 is rotated by 90 degrees to the holding restricted state, the knob plate portion 12a of the rotary knob 12 is rotated. The contact surface 12e, which is the bottom surface, faces the flange portion 4, so that the flange portion 4
When the flange 4 is moved to the side of the rotary knob 12, which is a direction deviating from 0, the flange 4 comes into contact with the contact surface 12e. Can be restricted and the knife 1 can be prevented from being pulled out.

When the knife 1 is to be withdrawn, the rotary knob 12 is rotated as shown in FIGS. 1, 4 and 5, and the knife 1 is pressed against the spring member 11 in this state. The knife 1 is withdrawn while being pressed.

In this case, a leaf spring is used as the spring member 11, and the rotating shaft 12 b of the rotating knob 12 is rotatably inserted into the sheath wall 5 a of the opening end 7 of the sheath body 5. 1
Since the spring member 11 is locked and fixed to the inner wall projection 12c of the sheath wall 2b, the rotary knob 12 can also be used for attachment by the spring member 12, so that the assembling workability can be improved and a simple structure can be achieved. Can be

The shapes of the sheath body 5, the locking projection 10 and the structure of the rotary knob are not limited to those in the above-described embodiment, but are designed by appropriately changing according to the shape of the knife. is there.

[0017]

According to the present invention, as described above, the rotary knob is rotated to the released state, and the blade is inserted into the sheath body. When the blade is completely inserted, the collar rides over the locking projection. The spring member presses the blade portion toward the locking convex portion, and when the rotating knob is rotated in the overriding state, the rotating knob can be brought into contact with the flange portion. Holding can be restricted, so that even if a strong movement or a large external force is applied, the knife can be prevented from being accidentally pulled out, and safety can be enhanced.

As described above, the intended purpose can be sufficiently achieved.
