2. Description of the Related Art In a conventional nail clipper, the lever is shifted using the fingertips of both hands, turned upside down to a usable state, and returned to the original state by the reverse operation after use. Although it is a simple operation, there is an inconvenience that it can not be done well without using both hands.

[0003] In the conventional method of fixing the lever when not in use, a stopper must be separately provided.

[0004]

Accordingly, the operation procedure of the conventional lever-type nail clipper until it can be used and the lever is folded down is simplified, the time is shortened, and one-handed operation is achieved. It can be operated with a light fingertip, the lever can be fixed without a stopper so that it does not move up, down, left and right when not in use, and it must be turned upside down when using, and the lever needs to be turned over The purpose is to solve the problem of eliminating.

Further, the fulcrum of the fulcrum portion on the surface of the lever is eliminated, and the fulcrum portion is provided on the back surface of the lever. When not in use, the fulcrum portion is stored between the upper blade body and the lower blade body so that the lever can be stored. Make it thinner, make it smaller overall and make it more functional.

[0006]

In order to achieve this object, a method according to the present invention is to install a push plate or a fulcrum rod on a back surface of a lever so as to form a fulcrum portion, and when the lever is not used, it is used. It is housed between the upper blade and the lower blade, and the lever is fixed on the upper blade without rubbing, while utilizing the fact that the upper blade and the lower blade have the ability to always spread. , The lever is automatically slid up by sliding the lever forward. For this reason, the lever fulcrum is structured to be located rearward of the pin regardless of whether the lever is used or not.

For the lever, a push plate having a fan-shaped arc portion with two grooves at the center of the back surface immediately after the pull bar, or a fulcrum bar having a curved outer arc portion with two grooves at the outer arc portion. With the arc portion or the outer arc portion facing backward, insert this push plate or fulcrum bar into the slit or fulcrum bar storage hole described later, and insert the tip portion between the upper blade body and the lower blade body. Bend.

Further, the arc portion and the outer arc portion described in "0007" are on the same circle as an arc drawn around the lever fulcrum.

The slit and the fulcrum rod storage hole are provided at the same position when the push plate and the fulcrum rod described in “0007” are lowered on the upper blade body surface, and have a size capable of penetrating the push plate and the fulcrum rod. A shallow groove which rises forward is provided on the upper blade body surface at the rear of the slit and the fulcrum bar storage hole.

[0010] The drawbar stopper hole is slightly shifted rearward from the same position immediately below the drawbar through-hole of the upper blade body. It will be in the form of contact with the drawbar.

When the drawbar stop hole is located immediately below the drawbar through hole and at the same position, the circumference of the drawbar fixing hole on the lower blade body surface is dug down with the same diameter as the drawbar head, and By making the upper blade body parallel and inserting the drawbar head, the same shape as “0010” is obtained when the nail clipper is used.

The drawbar through hole is formed in an elliptical shape with the front and rear major axes because of the mechanism by which the lever connected to the drawbar slides back and forth.

[0013] The diameter of the drawbar stopper hole described in "0010" or "0011" is larger than the diameter of the drawbar because of the structure in which the drawbar can be moved to the front.

The non-slip is positioned in front of the lever surface to facilitate folding and raising of the lever.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In FIG. 1, the upper blade 15
The upper blade body 15 comes into contact with the lever fulcrum 38 via the pull rod 36 and the pin 35 while the lower blade body 14 and the lower blade body 14 have a spreading force, the lever 31 is pushed up, and the push plate 6 is moved to the lever back surface 5.
And the groove c9 and the groove a4 engage with each other,
Since the push plate tip 10 is bent laterally, the push plate 6 is prevented from coming off the slit 3. The drawbar 36 is in contact with the rear part of the drawbar through-hole 2 and illustrates a so-called usable state.

In the same figure, the engagement between the groove a4 and the groove c9 and the contact point between the pin 35 and the pull bar 36 are flexible and have a shape that cannot be forced. In addition, push plate 6
Fulcrum 40 where the groove c9 of the upper blade contacts the groove a4 of the upper blade body surface 1
Is located at only one location, but the pin 35 is firmly supported at two other locations at the tip of the lever 31 (not visible from this figure, but see FIG. 8). The movement is smooth and stable.

FIG. 3 is an enlarged view of the periphery of the push plate 6 in a state where the lever 31 is raised, the push plate 6 is fixed to the lever back surface 5, and the groove c9 of the push plate 6 corresponds to the upper blade body surface. The groove c4 is engaged with the first groove a4, and furthermore, since the pull rod 36 has a backward force, even if the lever 31 is lowered as it is, the groove c9 does not come off from the groove a4 having the upwardly rising shape, without difficulty. Can cut nails.

FIG. 4 shows a state in which the lever 31 is being folded, in which the upper blade body 15 is connected to the lever fulcrum 38.
The arc 7 touches the rear of the slit 3 while pressing it,
Since the lever 31 is pushed forward, the pull rod 36 is located in front of the oval-shaped pull rod through hole 2.

In the state described above, if the lever 31 is pushed down as it is, the arc portion 7 comes off the slit 3 and the groove b8 meshes with the groove a4 on the upper blade surface 1, so that the lever 31 moves up, down, left and right. It does not move, resulting in the folded configuration shown in FIG.

Further, the lever fulcrum 38 in FIG. 4 has a structure which is always located behind the pin 35 regardless of whether the lever 31 is lifted or folded, and
In the same state, the lever contact surface 39 does not come into contact with the upper blade body surface 1, so that the upper blade body surface 1 attempts to lift the lever 31 regardless of the position of the lever 31. Becomes

Further, when the lever 31 is pushed down, the lever fulcrum 38 does not have the function of lowering the upper blade body 15, and is located away from the upper blade body surface 1 and located above.

In "0019", the lever 31
The upper blade body 15 still has the lever 3
1 has an upward force, the groove b8 is disengaged from the groove a4 of the upper blade body surface 1 only by sliding the non-slip 24 forward, and the lever 31 is sprung up.
The state is as described.

FIG. 5 shows the structure of the pull-stop hole 12 of the lower blade body 14.
A structure in which the periphery of 2 is dug down with the same size as the drawbar head 37, the dug surface is made parallel to the upper blade body surface 1, and the rear part of the drawbar through hole 2 is brought into contact when the drawbar 36 is installed. Has become. In other words, the pull bar 36 keeps the balance of the force in this position, and if the pull bar 36 is moved forward, a force for inevitably returning to the original position will be exerted. When the groove b8 and the groove c9 of No. 6 are engaged with the groove a4 of the upper blade body surface 1 together with the forward rising shape of the groove a4, they cannot be removed unless the slip stopper is pushed forward.

FIG. 6 shows the position of the pull-bar stopping hole 12 of the lower blade body 14 when the fulcrum bar 19 is installed as another method having the same function as the push plate 6. The position of the bar stopper hole 12 is slightly shifted rearward from the same position immediately below the draw bar through hole 2 of the upper blade body 15, so that when the draw bar 36 is installed, the draw bar through hole 2
It is structured to contact the rear. Therefore, the groove e21 and the groove f22 of the fulcrum bar 19 are formed in the groove d1 of the upper blade body surface 1.
When meshing with No. 7, it does not come off unless the non-slip is pushed forward, similarly to the description of "0023".

As a supplement to the description of “0023” and “0024”, the diameter of the drawbar stopper hole 12 and the drawbar 36
The diameter of the pull rod stopper hole 12 may be increased or the diameter of the pull rod 36 may be reduced,
It is desirable that the drawbar 36 has some backlash so that the drawbar 36 can smoothly move back and forth in the oval drawbar through hole 2. Further, as another method of making the upper blade body surface 1 and the lower blade body 14 described in “0023” parallel to each other, the same effect can be obtained even if the area immediately after the drawbar stopper hole 12 of the lower blade body 14 is bent inward. is there.

The shape of the arc portion 7 and the outer arc portion 20 formed between the groove b8 and the groove c9 of the pressing plate 6 and between the groove e21 and the groove f22 of the fulcrum bar 19 are the same even if they are linear. effective.

In addition, regarding the non-slip 24, the lever 3
If the movement of the lever 31 at the time of automatic splash raising from the folded state of 1 and a part to which a finger should be applied when the lever 31 is folded and a force should be applied is taken into consideration, the lever 31 is located in front of the lever surface 18. Is appropriate.

Further, the position where the push plate 6 and the fulcrum bar 19 are installed is desirably at the center portion 33 of the lever back surface immediately after the pull bar 36, whereby the force applied to the lever 31 can be reduced.

[0029]

Since the present invention is configured as described above, the following effects can be obtained as a result.

In the lever type nail clipper, a push plate serving as a fulcrum of the lever is provided on the back surface of the lever, and this push plate is fixed on the upper blade body when in use, and is passed through a slit when not in use. By storing the lever between the blade and the blade, the thickness of the lever can be reduced.

Also, by utilizing the spreading force of the upper blade body and the lower blade body, a state in which the groove b of the push plate and the groove a of the upper blade body are engaged and folded, only by pressing the non-slip with a fingertip. Can be easily released,
The lever can be raised automatically.

Further, when folding the lever, the state in which the groove c of the push plate on the back surface of the lever and the groove a of the upper blade body are engaged is pushed forward by a non-slip attached to the lever surface to release the engagement and fold. By engaging with another groove b provided in the push plate, the lever is fixed on the upper blade and does not move, and there is no need to turn the lever over.

Therefore, overall, the nail clippers can be made more compact, the required time can be reduced by one-touch operation, and the operability can be improved.
Effective for preventing mischief of infants.
