Description

[Detailed description of the invention] This invention particularly relates to a cutter knife in which the blade body can be stored inside the handle, and its purpose is to incorporate the protrusion and storage mechanism of the blade body inside the handle.
To enable easy disassembly and assembly of a handle.

Hereinafter, the first embodiment of the present invention will be explained according to FIGS. 1 to 5. As shown in FIG. 1, the handle 1 has a box-shaped body member 2 (see FIG. 2) and It consists of a metal cover 3 having a cross-sectional shape, and both upper and lower walls 2a and side walls 2b of the main body member 2.
A notch 4 is formed at the rear end of both corners of the upper and lower walls 2a to form a flexible arm 5 at the rear end of both the upper and lower walls 2a. A retaining protrusion 5a is formed at the tip of the flexible arm 5. A sliding surface 6 extending in the front-rear direction is provided in the center of the side wall 2b of the main body member 2 so as to form a stepped shape with respect to the upper and lower outer surfaces of the sliding surface 6. 2 mouth part 2
c also has a stepped shape with respect to both the upper and lower walls 2a of the main body member 2 and the upper and lower both sides of the side wall 2b. A guide groove 7 is formed in this slide surface 6 so as to extend in the front-rear direction.

As shown in FIGS. 4 and 5, a slide member 10 is installed inside the main body member 2, and its operating section 11
is exposed to the outside of the main body member 2 through the guide groove 7 and is in sliding contact with the slide surface 6, as shown in FIG. The slide member 10 is movable in the front-rear direction along the guide groove 7. Pattern 1
A blade 16 is fitted into the interior so that it can protrude from the front end opening 9 of the main body member 2, and a locking hole 17 formed in the blade 16 is inserted into a locking protrusion formed at the front end of the slide member 10. It is attached to part 12. Elastic beams 14 are formed by forming elongated holes 13 on both sides of the center of the slide member 10, and engagement protrusions 15 are provided protruding from the outside of the elastic beams 14. This engaging convex portion 15 is formed on both the upper and lower walls of the main body member 2.
It is possible to engage into the engagement recesses 8 formed in both the front and rear parts of a. As shown in FIG.
When the engagement protrusion 15 of the slide member 10 is engaged with both engagement recesses 8 on the rear side as shown in FIG. 5, the blade body 16 is housed in the handle 1.

Now, to assemble the handle 1, bend both flexible arms 5 of the main body member 2 toward the notch 4 against its elasticity, and fit the main body member 2 into the cover 3 as shown in FIG. . In this assembled state, both side edges 3a of the cover 3 are located on both sides of the guide surface 6 of the main body member 2. Further, the cover 3 is interposed between the opening 2c of the main body member 2 and the retaining protrusion 5a of the flexible arm 5, and does not fall off from the main body member 2. On the other hand, to disassemble the handle 1, bend both flexible arms 5 toward the notch 4 against its elasticity to disengage one end of the cover 3 and the retaining protrusion 5a of the flexible arm 5.
Remove the cover 3 from the main body member 2.

Next, the second embodiment will be explained with reference to FIGS. 6 to 11. In this second embodiment, the protrusion and storage mechanism of the blade body 16 are changed, and the basic structure of the handle 1 is the same as described above. This is the same as in the first embodiment. In this embodiment, retaining pins 18 and 1 are provided protruding from the rear end portions of the slide member 10 and the main body member 2.
A spring 20 is connected between the blades 9 and 9, and biases the slide member 10 rearward so that the blade 16 is normally housed in the handle 1, as shown in FIG. An engagement convex portion 15 is formed on the lower surface of the front end of the operating portion 11 of the slide member 10, and the slide member 10 is moved by a spring 20 so that the blade body 16 protrudes from the front end opening 9 of the handle 1, as shown in FIG. When the slide member 10 is moved forward against the bias of the slide member 10, the slide member 10 is engaged with an engagement hole 8 formed further forward than the front end of the guide groove 7 of the handle 1, thereby preventing the slide member 10 from moving. ing.

In this second embodiment as well, the handle 1 is disassembled and assembled in the same manner as in the first embodiment.

Note that in both of the embodiments described above, it is also possible to use only one flexible arm 5.

In the present invention described in detail above, a handle 1 is formed from a main body member 2 and a cover 3 into which the main body member 2 is fitted, and a notch 4 is formed in the rear end of the main body member 2 to make it flexible. A retaining protrusion that forms an arm 5 and is engaged with one end of the cover 3 when the main body member 2 is inserted into the cover 3 by bending the flexible arm 5 toward the notch 4 against its elasticity. 5a is formed on the flexible arm 5, and the cover 3 is interposed between the mouth portion 2c of the main body member 2 and this retaining protrusion 5a, so that the protrusion and storage mechanism of the blade body 16 can be controlled from the handle 1. Since the handle 1 can be easily disassembled and reassembled, the cover 3 can be reliably prevented from falling off from the main body member 2.
