Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to nail clippers, and specifically relates to a nail clipper with a case for preventing nails from scattering.

[Conventional technology]

Conventionally, in this type of nail clipper, as shown in Fig. 1, a case 6 is installed at a fixed position so as to close both openings of the nail clipper body 1, which prevents nails from scattering during cutting. Since it is not possible to leave very large openings near the cutting edges 2a and 3a of the double-edged blades 2 and 3 in order to prevent the nails from scattering, it takes time and effort to dispose of the cutting nails in the case 6 as it is.

Therefore, by making the case movable within a certain range in the longitudinal direction with respect to the nail clipper body, and making it possible to form the opening of the clipper near the cutting blade,
Nail clippers that not only prevent the cut nails from scattering but also allow the cut nails to be easily disposed of outside are also provided. (For example, see Utility Model Publication No. 52-27025 and Utility Model Publication No. 52-125975.) [Problem to be solved by the invention] However, in this type of nail clipper, the means for restricting the movement of the nail clipper body is the lower blade. This is done by engaging a long hole formed in the body with a protrusion formed on the bottom plate of the case, so considering that the lower blade body is usually made of metal, it is difficult to manufacture, and There was also a problem with the structure that had to become complicated.

The present invention has been made to solve these problems, and its purpose is to provide a nail clipper with a case for preventing nail scattering that is easy to manufacture and has a simple structure.

[Structure of the idea]

In order to achieve the above object, this invention fixes the upper blade body and the lower blade body to each other at their proximal ends, gives them elasticity in the direction of approaching and separating them, and provides elasticity on the tip sides of both the upper and lower blade bodies. A pivot pin is inserted between the upper and lower blade bodies near the proximal end of the formed upper and lower blade bodies, and a press operation lever is rotatably pivoted to the pivot pin on the outer surface of the upper blade body, and a nail clipper is formed. The nail clipper has a main body, and a nail scattering prevention case is attached to the nail clipper body to close both side openings between the upper and lower blade bodies, and the nail scattering prevention case has side plate parts that close both side openings between the upper and lower blade bodies. and a bottom plate part that covers the outer surface of the lower blade body, and is movable within a certain range in the longitudinal direction with respect to the nail clipper body, and an insertion hole is formed in the side plate part at a position where a stop member is attached, The stopper member is provided with a leg portion that is inserted into the insertion hole and projects inside the side plate portion, and the lower blade body is held between the leg portion and the bottom plate portion of the case. The part comes into contact with the pivot pin and stops at a moving position where the side plate parts almost close the openings on both sides of the upper and lower blade bodies, and there are cutting claw openings on both sides between the blade bodies corresponding to the vicinity of the cutting blades of the upper and lower blade bodies. The gist is that the blade is inserted between the inner surfaces of the upper and lower blade bodies and stopped at the moving position where the blade is formed.

[Effect]

When the nail scattering prevention case is moved toward the tip of the nail clipper body, the legs of the stopper member come into contact with the pivot pins at a position where the side plates of the case almost close the openings on both sides of the upper and lower blade bodies, and the case stops. movement is prevented.

In addition, when the nail scattering prevention case is moved toward the proximal end of the nail clipper body, the legs of the stopper member are moved to a position where the nail disposal openings are formed on both sides between the upper and lower blade bodies corresponding to the vicinity of the cutting blades of the upper and lower blade bodies. Since the part is inserted between the inner surfaces of the upper and lower blade bodies and stopped, movement of the case is prevented.

In addition, since the movement regulating means of the case for preventing claw scattering is configured such that the stop member comes into contact with the pivot pin and stops, or is stopped by being inserted into the gap between the upper and lower blade bodies, manufacturing is easy. Yes, and the structure is also simpler.

[Example] Hereinafter, the first example embodying this invention will be described as the second example.
To explain according to Figures 8 to 8, 1 is elasticity in the direction in which the upper blade body 2 and the lower blade body 3 are fixed to each other at their proximal ends so that the upper blade body 2 and the lower blade body 3 are expanded toward their distal ends, and are moved toward and away from each other. The nail clipper body has a
Cutting blades 2a and 3a are formed at the tips of the double blade bodies 2 and 3 to face each other, and a pivot pin 4 is inserted between the double blade bodies 2 and 3 in the vertical direction near the base end sides of the cutting blades 2a and 3a. The locking portion 4a formed at the lower end of the pivot pin 4 is locked to the outer surface of the lower blade body 3. Reference numeral 5 denotes a pressing lever rotatably pivoted to the upper end of the pivot pin 4 on the outer surface of the upper blade body 2, as shown in FIGS. 5 and 7.
A metal (or plastic) decorative plate 5 having a U-shaped cross section is formed in the mounting groove 5a formed on the periphery of the upper surface.
b are inserted and adhered to each other.

Reference numeral 6 denotes a nail scattering prevention case made of a metal plate (plastic may also be used) formed with a bottom plate part 6a and side plate parts 6b on both sides thereof, each having a U-shaped cross section.
a covers the outer surface of the lower blade body 3, and both side plate portions 6b can close the openings on both sides of the upper and lower blade bodies 2 and 3. As shown in FIG.
Cuts 7 and 8 are formed in the distal edges of both side plate portions 6b that protrude slightly from the distal edges of the side plate portions 6b, and insertion holes 9 are formed near the distal ends of both side plate portions 6b. 1
0 is a plastic stopper member consisting of a flat head 11 and a hook-shaped leg 12 protruding from the back side thereof, and the leg 12 has a downwardly bent portion 12a at its tip. , the horizontal part 12b of the leg part 12 has an elastic piece 1 that floats upward near the back side of the head part 11.
A U-shaped notch is formed to form 3. When the leg portions 12 of this stopper member 10 are inserted into the insertion holes 9 of the side plate portions 6b, the head 11 is locked to the outer surface of the both side plate portions 6b, as shown in FIG. The elastic piece 13 is engaged with the upper edge of the insertion hole 9 to prevent the stopper member 10 from coming off, and the legs 12 of the stopper members 10 that protrude inside the side plate portions 6b are inserted into the case 6. are brought close to each other.

The nail scattering prevention case 6 configured as described above is attached to the lower blade body 3 side of the nail clipper main body 1 with its stopper member 10 removed, and then the legs 12 of the stopper member 10 are inserted into the insertion holes of the side plate parts 6b. If you insert it into 9,
Bent portion 12a of leg portion 12 and bottom plate portion 6a of case 6
Since the lower blade body 3 is held between the nail clipper body 1 and the nail clipper body 1, the case 6 does not fall off from the nail clipper body 1, and furthermore, the case 6 is prevented from shaking in the vertical direction. And case 6
In this state, the nail clipper body 1 can be moved in the longitudinal direction.

Now, when you want to use nail clippers, use the second and third nail clippers.
As shown in the figure, the case 6 is moved toward the distal end of the nail clipper body 1 until the leg portion 12 of the stopper member 10 comes into contact with the pivot pin 4 of the nail clipper body 1 and is prevented from moving.
At this time, the notch 7 of the case 6 becomes a recess for accommodating the locking portion 4a of the pivot pin 4. In this state, the openings on both sides of the upper and lower blade bodies 2 and 3 are the upper and lower cutting edges 2a,
Both side plate parts 6 of the case 6 so that 3a is slightly exposed.
blocked by b. Then, when the side edge of the claw is inserted between the side edges of both cutting blades 2a and 3a through the notch 8 of the case 6 and the pressing operation lever 5 is pressed, the claw will scatter. It is reliably accommodated in the case 6 without any problems.

If you want to discard the cutting claw, one side edge of the leg 12 of the stopper member 10 comes into contact with the inner surface of the upper blade body 2 and is inserted between the inner surfaces of the upper and lower blade bodies 2 and 3, as shown in FIGS. 6 to 8. The case 6 is moved toward the proximal end of the nail clipper main body 1 until the case 6 is jammed and the movement of the case 6 is prevented by the resistance. At this time, as shown in FIG.
One side edge of the elastic piece 13 of No. 2 is also pressed downward,
Since the engagement state between the other side edge of the elastic piece 13 and the upper edge of the insertion hole 9 of the side plate portion 6b is maintained, the stop member 1
0 will never escape from case 6. In this state, a cutting nail discard opening S is formed on both sides between the double blade bodies 2 and 3 corresponding to the vicinity of the cutting edges 2a and 3a of the double blade bodies 2 and 3, and the cutting nail can be disposed of to the outside from here.

Next, another example of the stopper member 10 will be described.

[Effect of idea]

As detailed above, the nail scattering prevention case used for the nail clipper of this invention has both side plate parts that close the openings on both sides between the upper and lower blade bodies, and a bottom plate part that covers the outer surface of the lower blade body. On the other hand, it is movable within a certain range in the longitudinal direction, and an insertion hole is formed in the side plate portion at a position where a stop member is attached, and the stop member is inserted into the insertion hole and protrudes inside the side plate portion. The lower blade is held between the legs and the bottom plate of the case, and the legs are in a moving position such that both side plates substantially close the openings on both sides of the upper and lower blades. It comes into contact with the pivot pin and stops, and it also stops when it is sandwiched between the inner surfaces of the upper and lower blades at a moving position that forms a cutter opening on both sides between the upper and lower blades corresponding to the vicinity of the cutting edge of the upper and lower blades. By doing so, when the case is cut, when the case is moved to the position where the stopper comes into contact with the pivot pin, the openings on both sides of the upper and lower blade bodies are almost completely covered by the side plates of the case, preventing the cut nails from scattering. can be prevented. Also, after cutting, if you move the case to the position where the stopper member is inserted between the inner surfaces of the upper and lower blades,
Since the cutting nail disposal opening is formed on both sides between the two blade bodies corresponding to the vicinity of the cutting blade, the cutting nail can be easily disposed of to the outside through the disposal opening. In particular, the gap between the inner surfaces of the upper and lower blade bodies and the pivot pin of the pressing lever can be effectively used as means for regulating the movement of the case, and a long hole can be formed in the lower blade body, which is usually made of metal, as in the conventional case. Since there is no need for this, manufacturing is easy and the structure can be simplified, which is an excellent effect.
