Description

[Detailed explanation of the idea] Purpose of invention (Industrial application field) This idea is related to nail clipping.

(Prior art) As a conventional nail clipper, for example,
There is one shown in Publication No. 18409. In this nail clipper, the upper blade body and the lower blade body are fixed to each other on the rear end side and have elasticity in the direction of approaching and separating, and the upper and lower blade bodies are formed near the upper and lower cutting blades formed on the front end side of the upper and lower blade bodies. A support shaft extending in the left-right direction between the upper and lower blade bodies is supported by a support part provided on the lower blade body, and this support shaft has a direction in which it approaches the lower blade body on the upper blade body during use. A press rod that presses the blade is supported so as to be rotatable in the vertical direction, and the press rod can be rotated below the lower blade body when not in use.

(Problem that the invention aims to solve) However, with this nail clipper, there is no means to restrict the expansion of the upper blade body relative to the lower blade body, so if a large expansion force is applied to both the upper and lower blade bodies, both the upper and lower blades will open. The body plastically deforms and opens more than necessary, causing problems during use, such as the rising angle of the press rod relative to the upper blade body becoming large, making it difficult to place the thumb on the press rod. Furthermore, it is difficult to manufacture the upper and lower blades with a constant amount of expansion, and the amount of expansion varies from product to product, causing a decrease in product value.

Therefore, the present invention solves this problem by devising a means for regulating the expansion of the upper and lower blades with a simple structure.

Structure of the invention (means for solving the problems) That is, as shown in the drawings of the embodiments described later, the invention consists of an upper blade body 1 and a lower blade body 2 that are fixed to each other at their rear end sides so that they can be separated from each other. has elasticity in the direction of approaching and separating, and extends in the left-right direction between the upper and lower blade bodies 1 and 2 in the vicinity of the upper and lower cutting edges 1a and 2a formed on the front end sides of the upper and lower blade bodies 1 and 2. is supported by a support part 3 provided on the lower blade body 2, and this support shaft 4 has a press rod 7 in the vertical direction that presses the upper blade body 1 in a direction to approach the lower blade body 2 when in use. In this nail clipper, the upper blade body 1 is provided with an expansion restricting portion 5, and the upper blade body 1 is provided with an expansion regulating portion 5, and the upper blade body 1 is provided with an expansion regulating portion 5, which allows the push rod 7 to be rotated below the lower blade body 2 when not in use. The regulating portion 5 is formed with a locking hole 6 into which the support shaft 4 of the press rod 7 is inserted, and the support shaft 4 is inserted into the locking hole so as to restrict the expansion of the upper and lower blade bodies 1 and 2 in the direction of separation. It can be locked to 6.

(Function) In the nail clipper configured in this way, the fourth
As shown in the figure, the expansion of the upper and lower blade bodies 1 and 2 is done using the support shaft 4.
It is regulated by the locking between the and the locking hole 6. During use, the press rod 7 is rotated onto the upper blade body 1 as shown in FIG. 1 and 2 approach each other, and both the upper and lower cutting edges 1a and 2a come into contact with each other. Also, when not in use, the push rod 7 is
Rotate the lower blade body 2 downward.

(Example) Hereinafter, a first example of the present invention will be described with reference to FIGS. 1 to 4 and FIG. 7.

As shown in FIGS. 1 and 2, the upper blade body 1 and the lower blade body 2 are fixed to each other at their rear end sides, and each has elasticity in the direction of moving toward and away from each other. Upper and lower cutting edges 1a and 2a are formed at the front ends of the upper and lower blade bodies 1 and 2, respectively. As shown in FIGS. 3, 4, and 7, support portions 3 are integrally provided on both left and right sides of the lower blade body 2 in the vicinity of the upper and lower cutting edges 1a, 2a, and these support portions Support hole 3a formed in 3
A support shaft 4 is inserted between the upper and lower blade bodies 1 and 2 so as to extend in the left-right direction.

The upper blade body 1 corresponds to both support parts 3 of the lower blade body 2.
Expansion regulating portions 5 are integrally provided downwardly on both left and right sides of the support portion 3 and overlapped with the outer sides of both support portions 3 . This expansion regulating part 5 has a locking hole 6 for the upper and lower blade bodies 1 and 2.
The support shaft 4 is formed to extend in the direction of approach and separation, and both ends of the support shaft 4 are inserted into both of the locking holes 6 . In this state, the lower end 6 of both locking holes 6 is attached to the support shaft 4.
a is locked, the expansion of the upper and lower blade bodies 1 and 2 in the direction of separation is restricted, and the upper and lower blade bodies 1 and 2 are prevented from opening beyond a certain level.

As shown in Figures 1, 2 and 7, the press rod 7 consists of an upper plate part 8 and both side plate parts 9 bent on both left and right sides of the front part. It protrudes forward from the front edge 8a of the plate portion 8. Both ends of the support shaft 4 are inserted into the support hole 10 formed in the protruding portion 9a on the outside of the expansion restriction portion 5 and caulked, and the press rod 7 is moved vertically around the support shaft 4. It is rotatable.

Now, when in use, the press rod 7 is rotated onto the upper blade body 1 as shown in FIG.
a comes into contact with the upper blade body 1 and can press the upper blade body 1 in the direction of approaching the lower blade body 2. and,
When this press rod 7 is pressed down, the support shaft 4 is moved into the locking hole 6.
The upper and lower blade bodies 1 and 2 approach each other while moving upward relative to each other, and the upper and lower cutting blades 1a and 2a come into contact with each other. Also, when not in use, the push rod 7 is
is rotated below the lower blade body 2, and the lower blade body 2 is inserted between the side plate portions 9 and locked.

On the other hand, when assembling this nail clipper, the upper and lower blade bodies 1 and 2 are fixed to each other with a substantially constant expansion amount that is larger than the expansion amount when assembled, and the upper and lower blade bodies 1 and 2 are pressed and narrowed. Then, the press rod 7 is placed on top of this, and the support shaft 4 is inserted through them. Therefore, the amount of expansion of the upper and lower blade bodies 1 and 2 can be made constant.

In addition, as shown in FIGS. 5 and 6, the support part 3 of the lower blade body 2 and the expansion restriction part 5 of the upper blade body 1 are connected to the upper and lower blade bodies 1,
2 may be formed separately and spot welded to the inside thereof.

Effects of the invention In short, according to the present invention, the expansion of the upper and lower blade bodies 1 and 2 can be regulated with a simple structure, so even if a large expansion force is applied to the upper and lower blade bodies 1 and 2, The upper and lower blade bodies 1 and 2 do not open beyond a certain level, and the rising angle of the press rod 7 with respect to the upper blade body 1 is always constant during use, making it easier to place the thumb on the press rod 7, thereby eliminating problems during use. . Further, the opening amount of the upper and lower blade bodies 1 and 2 can be made constant, and the opening amount is constant for all products, so that the commercial value can be maintained.
