Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention relates to a support structure for the blade in a nail clipper with a storage case.

(Problems to be solved by conventional techniques and inventions) In nail clippers, in order to improve the appearance of the nail clipper and to prevent the cut nails from scattering, it is conceivable to put the upper and lower blades in a storage case. In this case, it is necessary to position the upper and lower blades in the storage case so that they do not move inadvertently during use.

For example, a storage case is formed by a bottom wall, left and right side walls, and a rear wall, and the upper side is opened as the overlapping part of the pressing operation lever for the upper blade body, and the front side is opened as the exposed part of the cutting edge of the upper and lower blade bodies. In this case, the downward, left-right, and rearward movements of the upper and lower blades can be restricted by the bottom wall, left and right side walls, and rear wall of the storage case, but the forward and upward movement of the upper and lower blades movement cannot be regulated.

Therefore, the present invention is devised to prevent the upper and lower blades from moving inadvertently in any direction during use, even though the upper and lower blades can be easily attached to the storage case.

Structure of the invention (means for solving problems) That is, as shown in the drawings of the embodiments described later, the invention consists of a storage case 1 with a bottom wall 2 and left and right side walls 3.
and a rear wall 4, the rear end of the bottom wall 4 is provided with a hole 5 that opens downward, and the rear wall 4 is provided with a protrusion 6 extending obliquely downward to the front thereof. The inner surface of the part 6 is used as a slide guide plate 6a, and a blade locking part 6b is formed at the tip thereof. A plate part 9 is integrally provided downward from the rear ends of the upper and lower blade bodies 7 and 8, and the hole 5 is provided at the lower end of the plate part 9.
A locking protrusion 9a that is inserted and locked in the plate part 9 is provided, and a locking hole 10 is provided in which the blade locking part 6b of the protrusion 6 of the plate part 9 is inserted and locked. The base end portion of a pressing lever 13 for pressing the upper blade body 7 is rotatably supported on the front end portions of the left and right side walls 3.

(Function) Then, by sliding the plate portion 9 with respect to the slide guide portion 6a of the storage case 1,
The locking protrusion 9a of the plate part 9 is locked in the hole 5 of the storage case 1 so that the upper and lower blade bodies 7, 8 cannot be detached from the front of the storage case 1, and the locking protrusion 9a of the plate part 9 is locked in the locking hole 10 of the plate part 9. The blade locking portion 6b of the protrusion 6 is locked to the storage case 1 in such a manner that the base ends of the upper and lower blades 7, 8 cannot be released upwardly, and furthermore, the upper part of the front ends of the upper and lower blades 7, 8 is locked by the pressing lever 13. By being irremovably supported, the upper and lower blade bodies 7 and 8 can be easily attached to the storage case 1, and will not fall off inadvertently.

(Example) An example of the present invention will be described below with reference to the drawings.

The storage case 1 has a bottom wall 2, left and right side walls 3, and a rear wall 4.
The top and front sides are open. A pair of left and right locking holes 5 are formed in the rear end corners 2a of the bottom wall 2 of the storage case 1, and a pair of locking holes 5 on the left and right sides are formed in the upper inner surface of the rear wall 4 of the storage case 1. A locking projection 6 is provided as an extending projection, and the inner surface of this projection 6 serves as a slide guide plate 6a, and a blade locking portion 6b is formed at its tip.

The upper and lower blade bodies 7, 8 are fixed to each other at their rear ends, and have elasticity in the vertical direction at the cutting edges 7a, 8a formed at their front ends. A locking plate portion 9 serving as a plate portion is bent downward at the rear end of the lower blade body 8, and a pair of left and right locking protrusions 9a are formed at the lower end edge of the locking plate portion 9. Further, a locking hole 10 is formed at a bent corner of the locking plate portion 9 facing the upper blade body 7.

The upper and lower blade bodies 7 and 8 are fitted and stored in the storage case 1, and the cutting edges 7a and 8a of the upper and lower blade bodies 7 and 8 are exposed from the front end side of the storage case 1. In this state, both the left and right side surfaces 11 of the upper and lower blade bodies 7 and 8 overlap the inner surfaces of the left and right side walls 3 of the storage case 1, and the rear end surface 12 of the upper blade body 7
The locking plate portion 9 of the lower blade body 8 is overlapped with the inner surface of the rear wall 4 of the storage case 1, and the lower surface on the cutting edge 8a side of the lower blade body 8 and the lower edge of the locking plate portion 9 are on the bottom wall. It is in contact with 2. As a result, movement of the upper and lower blade bodies 7 and 8 in the left-right direction, rearward direction, and downward direction within the storage case 1 is restricted. Furthermore, in this state, the locking protrusion 9a of the locking plate part 9 is locked in the locking hole 5 of the storage case 1 so that the upper and lower blade bodies 7, 8 cannot be detached from the front with respect to the storage case 1. The blade locking portion 6 of the locking protrusion 6 is inserted into the locking hole 10 of the locking plate portion 9.
b is locked to the storage case 1 so that the base ends of the upper and lower blade bodies 7 and 8 cannot be removed upwardly. As a result, the movement of the upper and lower blade bodies 7 and 8 in the forward and upward directions within the storage case 1 is restricted. Furthermore, when attaching the upper and lower blade bodies 7 and 8 to the storage case 1, the locking plate part 9 is slid along the slide guide part 6a, so it can be easily attached with one touch, and once attached, Locking hole 1
Since the blade locking portion 6b is locked at 0, movement is reliably regulated.

A shaft support 1 is provided on the lower surface of the base end of the pressing operation lever 13.
4 is formed, and this pivot support 14 is fitted between the front ends of the left and right side walls 3 of the storage case 1 on the upper blade body 7, and is rotatable in the vertical direction with respect to the left and right side walls 3 by a support shaft 15. is supported by This shaft support 1
The cutting edge 7a side of the upper blade 7 is pressed against the upper blade 4 by its elasticity, and the upper and lower blades 7 and 8 are held between the coaxial support 14 and the bottom wall 2 of the storage case 1. As a result, the front ends of the upper and lower blade bodies 7 and 8 are restricted from moving in the vertical direction within the storage case 1.

In the nail clipper with a storage case configured as described above, when the pressing operation lever 13 is pushed down as shown in FIG.
is pressed against its elasticity, and the upper and lower blade bodies 7, 8
The cutting edges 7a and 8a of the two come into contact with each other.

Even during this use, the upper and lower blade bodies 7, 8 are securely positioned relative to the storage case 1 as described above, so they will not move inadvertently.
It becomes much easier to use.

In addition, each of the locking protrusions 9a, 6 and the locking hole 5,
By changing the shape of the upper and lower blades 7 and 8, it becomes possible to restrict the movement of the upper and lower blades 7 and 8 in all vertical, lateral, and front-back directions, thereby preventing the overlapping or contacting of the upper and lower blades 7 and 8 with respect to the storage case 1. connection is not necessarily required.

Effects of the invention In short, according to the invention, the upper and lower blade bodies 7 and 8 can be positioned and attached from above with a single touch operation to the storage case 1 in which the bottom wall 2, left and right side walls 3, and rear wall 4 are integrated. Once installed, the upper and lower blades 7 and 8 are reliably positioned with respect to the storage case 1 by the action of the pressing operation lever 13 supported on the front side of the upper and lower blades 7 and 8, so that they will not come off accidentally. It has the excellent effect of not moving and being very easy to use.
