[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting tool that can be used by switching to scissors or a knife.

[0002]

2. Description of the Related Art Since scissors and knives have different cutting functions, it is difficult to use them both.

[0003]

[Problems to be Solved by the Invention] For example, when fishing, scissors and a knife are indispensable for cutting the fishing line and opening the belly of the fish, but it is not portable to prepare both. There is a problem in that workability is not good if both hands are switched according to the work. It should be noted that it is extremely unwieldy and even dangerous to use the knife as a substitute with the scissors open.

Therefore, the present invention provides a convenient cutting tool which is always housed in a grip case and can be protruded when necessary to switch to scissors or a knife for quick and safe cutting work. Squeezing is a technical problem to be solved.

[0005]

[Means for Solving the Problems] For this purpose, the following cutting tools were created. That is, according to the present invention, the stationary blade body and the moving blade body are connected so as to be opened / closed and relatively slidable via a pivot that engages with the elongated hole of the stationary blade body, and then the stationary blade body and the moving blade body are connected to each other. The housing is housed in a grip case so as to be retractable in a direction in which the elongated hole extends, and further comprises a spring for urging the moving blade body projecting from the grip case to expand the stationary blade body, When the stationary blade and the moving blade are submerged in the grip case, the elongated hole and the pivot allow the stationary blade to follow the moving blade and project from the grip case when the moving blade is extended. It is characterized in that only the stationary blade body can be grasped and projected from the case when the stationary blade body is extended.

[0006]

[Function] When the stationary blade body and the movable blade body are immersed in the grip case, when the movable blade body is extended, the stationary blade body whose end of the elongated hole is pushed by the pivot is driven by the movable blade body. And project from the grip case. Since the moving blade protruding from the grip case is urged by the spring and is in an expanded state with respect to the stationary blade, the cutting tool can be used as "scissors" if the moving blade is closed. Then, by sliding the stationary blade body and the moving blade body relative to each other, the protruding moving blade body is immersed in the grip case, or when the stationary blade body and the movable blade body are immersed in the grip case. The cutting tool can be used as a "knife" by extending only the stationary blade. After use, hold the stationary blade in the case.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, a gripping case 1 for a cutting tool
A slide groove 1a having a U-shaped cross section is formed in the longitudinal direction (hereinafter, simply referred to as a "case"), and a slide groove 1a 'having a slightly wider width is formed so as to overlap the slide groove 1a. A window hole 1b extending in the longitudinal direction and a locking recess 1e are formed on one side surface of the slide groove 1a.
An opening 1c extending in the longitudinal direction and an engagement hole 1d are formed on one side surface of a '. A stationary blade body 2 of the illustrated shape is slidably fitted in the slide groove 1a,
The protrusion 2b formed on the side of the main body 2a of the stationary blade 2 is covered with a slider 4a for operating with a finger and then inserted into the window hole 1b. An elongated hole 2d is formed from the center of the main body 2a to the rear, and a locking projection 2c and a slit 2e are formed at the rear end of the main body 2a. This locking projection 2c is the locking recess 1 of the slide groove 1a.
It is for locking the slide of the stationary blade body 2 at two positions, the retracted position and the protruding position, by engaging with e or the window hole 1b.

Further, a moving blade body 3 of the illustrated shape is slidably fitted in the slide groove 1a 'and is inserted into the elongated hole 2d of the stationary blade body 2 and the round hole 3a of the moving blade body 3. A pair of upper and lower rivets 5a and 5b (also referred to as pivots) connect the overlapping blade bodies 2 and 3 in a relatively slidable manner and serve as a fulcrum for opening and closing of the blade bodies 2 and 3. In addition,
The positional relationship between the rivets 5a and 5b and the slot 2d is shown in FIG.
As shown in (a) and (b), when both blade bodies 2 and 3 are both in the retracted position or the projected position, the rivet 5
While a and 5b are located on the left end side of the elongated hole 2d in the figure,
As shown in (c), the moving blade body 3 is in the retracted position,
When the stationary blade body 2 is in the protruding position, the rivet 5
It is set so that a and 5b are located on the right end side of the elongated hole 2d in the figure.

A projection 3b formed on the side of the moving blade body 3
Is covered with a slider 4b for operation with a finger and then inserted into the opening 1c of the case 1. Also,
At the rear end of the moving blade body 3, a projection 3c that can be engaged with and disengaged from the engagement hole 1d.
Is formed, and a narrow plate-shaped spring 6 is attached. The spring 6 is configured such that the tip end thereof is brought into contact with the side surface of the slide groove 1a 'to urge the moving blade body 3 in the counterclockwise rotation direction in the drawing. And the double-edged body 2,
The case 1 containing 3 is covered with a lid 7 that closes the upper opening and the rear end.

Next, the operation of the cutting tool having the above construction will be described with reference to FIG. As shown in FIG. 2A, a stationary blade body 2 and a moving blade body 3 are housed in the case 1, and the heads of the sliders 4 a and 4 b project from the side portions of the case 1. To use the cutting tool in this state as "scissors", hold the case 1 by hand, push down the slider 4b with your thumb, and disengage the protrusion 3c from the engagement hole 1d.
Push the slider 4b forward (left side in the figure). When the moving blade body 3 is pushed, the rivet 5a comes into contact with the end of the elongated hole 2d and pushes the stationary blade body 2. Then, since the locking projection 2c can be displaced by the amount of the slit 2e, it is disengaged from the locking recess 1e, and subsequently,
The moving blade body 3 and the stationary blade body 2 which follows this slide groove 1a,
Sliding along 1a ', the double-edged bodies 2 and 3 are case 1
Stick out from.

The slider 4b abuts on the end of the window hole 1b (see FIG. 1), and the locking projection 2c is attached to the window hole 1b.
The position of the stationary blade body 2 is determined by engaging with the edge portion of b. At this time, since the moving blade body 3 is biased by the spring 6,
When the force of the thumb is loosened, as shown in FIG. 2 (b), the rear end of the moving blade body 3 pops out of the opening 1c together with the slider 4b, and the blade bodies 2 and 3 are opened. Therefore, the slider 4b is pushed down with the thumb to rotate the moving blade body 3 in the closing direction to cut the object to be cut.

Next, when the blades 2 and 3 are protruding from the case 1, if the slider 4b is pushed down by the thumb and pulled back, the moving blade 3 is moved as shown in FIG. 2 (c).
Slides in the slide groove 1a 'and then the protrusion 3
It is held at a position where c and the engaging hole 1d are engaged with each other. Then, the cutting tool with only the stationary blade body 2 protruding can be used as a "knife". After that, when the slider 4a is pulled back backward, the engagement between the locking projection 2c and the window hole 1b is released,
The stationary blade 2 slides in the slide groove 1a,
The storage state shown in FIG.

That is, in the cutting tool of this embodiment, by operating the slider 4b, the case 1 is moved to the stationary blade 2
Since the moving blade body 3 and the moving blade body 3 can be projected at the same time, and subsequently only the moving blade body 3 can be immersed in the case 1, the "scissors" and the "knives" can be operated by a one-touch operation with the thumb. , And can be switched. By operating the slider 4a when the blades 2 and 3 are in the protruding state, the stationary blade 2 and the moving blade 3 can be accommodated in the case 1 all at once, and the slider 4a can be operated. Te blade 2
Only the case 1 can appear and disappear from the case.

By the way, in the above embodiment, the engaging projection 2c is easily elastically displaced due to the presence of the slit 2e, and when the stationary blade 2 slides in the slide groove 1a, the engaging projection 2c is engaged. The protrusion 2c is formed so as to be disengageable from the locking recess 1e or the window hole 1b. Another example of this stopper mechanism will be described below with reference to FIG. The parts corresponding to those in the above-described embodiment are designated by the same reference numerals. The resin case 1 shown in FIG. 3 has projections 1f, 1f formed on the bottom of the slide groove 1a, while the stationary blade body 2 has a locking hole 2f having a size corresponding to the projection 1f. There is. The case 1 has a thin wall in the vicinity of the protrusion 1f so that the protrusion 1f is easily elastically displaced in the direction of the arrow in the figure. The engagement hole 1d in the above-described embodiment is a groove in this example. That is, in this example, the resin molding die of the case 1 is simplified as compared with the above-described embodiments, and it is effective in suppressing the manufacturing cost of the molding die. For the same reason, although not shown, the locking hole 2f on the stationary blade 2 side can be replaced with a projection, and the projection 1f on the slide groove 1a side can be replaced with a hole, and the shape of the window hole 1b can also be a mold. Can be easily removed.

In the embodiment described above, the stationary blade 2
Also, the sliders 4a and 4b are mounted on the protrusions 2b and 3b provided in the respective plate surfaces of the moving blade body 3, but the sliders 4a and 4b can be protruded from the case 1 in a bent state. Further, the sliders 4a and 4b may be omitted by directly operating the protrusions 2b and 3b with fingers. Also,
Although the spring 6 is a leaf spring, a spiral spring or the like may be used instead. In addition, it is needless to say that the present invention can be implemented in various modified modes based on the knowledge of those skilled in the art.

[0016]

As described above, since the cutting tool of the present invention can be used by switching to scissors or a knife at any time,
It is possible to easily and quickly cut according to the work content.
Moreover, since the scissors and the knife are housed together in the grip case, the portability is good and the safety is high.
Therefore, if it is carried when fishing, the cutting work becomes easy and it is very convenient.
