Description

[Detailed explanation of the idea] Technical field This idea is related to nail clipping.

Prior Art As shown in Figures 8 and 9, a conventional nail clipper has an upper blade body 1 and a lower blade body 2 fixed to each other at their base ends, and each tip has elasticity in the direction of separating them from each other. Then, insert the pin 9 between the upper and lower blade bodies 1 and 2 near the upper and lower cutting edges 7 at the tips of the upper and lower blade bodies 1 and 2, and insert the press rod 13 into the pin 9 on the outer surface of the upper blade body 1. On the other hand, it was mounted on 12 shafts so that it could rotate.

When the push rod 13 of this nail clipper is not in use as shown in FIG. Force point protrusion 13 for pressing body 1
A will be in a state where it protrudes upward. As a result, the overall shape of the nail clipper was unsightly, and it also had the disadvantage of being bulky.

Therefore, there are devices in which the force point protrusion is removed from the press rod, and instead a force point member is rotatably provided between the press rod and the upper blade body (for example,
(See Publication No. 146006). This force point member is provided with a protruding engagement protrusion that engages with the press rod during use. Since this engaging protrusion comes into contact with the push rod and the upper blade body when not in use, a space is created between the upper blade body and the force point member, and between the push rod and the force point member, resulting in the same defects as in the case described above. It was hot. In order to prevent this, for example, in the blade described in the Blade Publication, the upper blade had to be shaped like a step.

Purpose The purpose of this invention is to eliminate these drawbacks by eliminating interference between the engaging protrusion of the force point member and the upper blade body and press rod, thereby making the whole compact and providing a good external appearance. Our goal is to provide nail clippers that will make you feel better.

Examples Examples of embodiments of this idea are shown in Figures 1 to 1.
This will be explained according to FIG.

As shown in FIGS. 1 and 2, the upper blade body 1 and the lower blade body 2, which have the same width, are fixed to each other at their proximal ends, and each has elasticity in the direction of separation. Cutting edges 7 are provided at the tips of the upper and lower blade bodies 1 and 2, respectively.

A pin 9 is inserted into the tips of the upper and lower blade bodies 1 and 2 from below. A support shaft 12 extending on both left and right sides of the blade bodies 1 and 2 is inserted into the tip end 9a of the pin 9 as a support shaft protruding from the upper surface of the upper blade body 1, and a push rod 13 is formed at the base end at both ends thereof. bifurcated connecting part 1
4 is supported, and the push rod 13 is rotatable about the support shaft 12.

The push rod 13 has the same width in the left and right sides as the width in the left and right sides of the upper and lower blade bodies 1 and 2, and is bent slightly downward at approximately the center in the longitudinal direction.

On the lower surface of the press rod 13, a hooking recess 15 is formed at the distal end, as shown in FIG. Power point protrusion 1 extending in the width direction
3a is provided.

The cover 17, which has a reverse channel cross-section, is attached so as to cover the upper surface of the upper blade body 1, excluding the tip from which the pin 9 is protruded, and both sides of the upper and lower blade bodies 1 and 2, and extends from the base end of the upper wall 17a. The lower wall 17b covering the outer surface of the base end of the lower blade body 2 is bent. Furthermore, engaging portions 18 are projected upward on both sides of the tip of the lower wall 17b, and the engaging portions 18 are slidable in sliding grooves 2a cut out on both sides of the base end of the lower blade body 2. When the cover 17 is inserted, the cover 17 covers both sides of the upper and lower blade bodies 1 and 2 as shown in FIG. It's summery.

Incidentally, reference numeral 19 denotes an insertion recess for inserting a nail formed at the tip of the side wall 17c for preventing the nail from scattering in the cover 17.

Support portions 20 are formed protruding from both sides of the upper wall 17a of the cover 17 at the substantially central portion, and between the support portions 20, the base end of a square frame-shaped force point member 21 is rotatably mounted on a shaft 22.

When in use, the force point member 21 is folded down to the upper wall 17a on the distal end side of the cover 17 as shown in FIG. 13a. Further, when the force point member 21 is not in use, it is folded down to the proximal upper wall 17a of the cover 17 as shown in FIG.
It can be held in pressure contact with the base end surface of the upper blade body 1 through the. Then, in a state where the engagement protrusion 23 is pressed against the base end surface of the upper blade body 1, when the push rod 13 is superimposed on the upper blade body 1 side, the engagement protrusion 16 of the push rod 13 is inserted into the hollow part of the force point member 21. It is now possible to press and hold.

A method of using the nail clipper configured as above will be explained.

Now, when in use, as shown in FIGS. 1 and 2, the force point member 21 is pushed down to the proximal end side of the upper part 17a of the cover 17, and while the force point protrusion 13a is engaged with the engagement protrusion 23, the press rod 13 is inserted into the upper blade. It is arranged diagonally with respect to the body 1.

In this state, when the press rod 13 is pressed in the opposite direction of the arrow P, the force point protrusion 13a
The cutting blade 7 of the upper blade body 1 is moved in the closing direction via the force point member 21 and the cover 17 while resisting the elasticity of the
Close both the upper and lower cutting blades 7.

On the other hand, when the pressure on the press rod 13 is released, the cutting edge 7 of the upper blade 1 is separated from the cutting edge 7 of the lower blade 2 due to the elasticity of the upper and lower blade bodies 1 and 2, resulting in the open state shown in FIG. Return.

Next, when this nail clipper is not used, rotate the push rod 13 in the direction of the arrow P to the position indicated by the chain line in FIG.
3 is held in pressure contact with the base end surface of the upper blade body 1 via the cover 17. Then, the press rod 13 is rotated in the opposite direction of the arrow P, and the engagement protrusion 16 is held in pressure contact with the force point member 21 and overlapped with the upper blade body 1 (see FIG. 4).

In this way, when not in use, the push rod 13 is attached to the upper blade body 1.
The point of effort protrusion 13
Since a does not protrude upward, the entire structure can be made compact.

In particular, since the engagement protrusion 23 of the force point member 21 is held in pressure contact with the base end surface of the upper blade body 1 when not in use, the contact between the engagement protrusion 23 and the push rod 13 or the upper blade body 1 may be the cause. There will no longer be any space between them, making the entire nail clipper more compact.
The appearance of the nail clipper also improves.

In this embodiment, by sliding the cover 17 in the direction of the arrow S, both sides of the tips of the upper and lower blade bodies 1 and 2 are opened as shown by the chain line in FIG. The nail can be ejected from the openings on both sides.

Effects As detailed above, this invention fixes the upper blade body 1 and the lower blade body 2 to each other at their base ends, gives each tip part elasticity in the direction of separating them from each other, and allows both the upper and lower blades to A push rod 13 that can be held overlappingly on the upper blade body 1 side with respect to the support shaft 12 provided on the tip side of the bodies 1 and 2
is rotatably supported at its base end, and when in use, the tip is interposed between the base end of the press rod 13 and the tip of the upper blade 1, and is pressed by the press rod 13 to move the upper blade 1 to the lower part. It is pressed toward the blade 2 side, and when not in use, it is reversed to the base end of the upper blade 1 and is located between the tip of the press rod 13 superimposed on the upper blade 1 side and the base end of the upper blade 1. A force point member 21 is provided above the upper blade body 1 so as to be rotatable with respect to the support portion 20, and the force point member 21 is provided with a protruding engagement protrusion 23 that can engage with the press rod 13 during use, Since the engaging protrusion 23 can be held in pressure contact with the base end surface of the upper blade body 1 when not in use, the press rod 13 can be superimposed on the upper blade body 1 side without being turned upside down, and this engagement There is no longer a space created between the mating protrusion 23 and the press rod 13 or the upper blade 1 due to their contact, making the nail clipper more compact as a whole, and improving the external appearance of the nail clipper. .
