Description

[Detailed description of the invention] [Industrial application field] The present invention relates to nail clippers.

[Prior Art] A conventional nail clipper shown in FIG. 10 is generally used. When this nail clipper is not in use, the protrusion 3 formed on the upper surface of the base end of the operating lever 1 is in a state of greatly protruding upward, making the front end of the nail clipper high and bulky. was.

[Problems to be Solved by the Invention] However, in the recent product market, there is a demand for nail clippers with a smarter shape that eliminates the clunkiness caused by the bulkiness of the front end seen in conventional nail clippers.

An object of the present invention is to reduce the height of the front end of the nail clipper by reducing the protrusion height of the protrusion formed on the upper surface of the base end of the operating lever as much as possible.

[Means for Solving the Problem J To achieve the above object, the nail clipper of the present invention was constructed as follows.

An engagement protrusion consisting of an engagement protrusion or an engagement protrusion is provided on the upper surface of the front end of the upper blade body. A recess is formed on the lower surface of the proximal end of the operating lever at a position corresponding to the engaging protrusion of the upper blade, into which the engaging protrusion of the upper blade can engage when not in use.

Further, an engagement protrusion may be provided protruding from the back surface of the recess on the lower surface of the operating lever, so that the engagement protrusion of the upper blade body and the engagement protrusion of the operating lever come into contact with each other in the operating state.

[Operation] In the operating state in which the engagement protrusion on the upper surface of the upper blade body and the upper surface of the operating lever are joined, the operating lever can be pressed using the supporting shaft of the base end of the operating lever as a fulcrum and the joint portion as a point of force. By pressing the operating lever, the cutting blade at the tip of the blade closes against the elasticity of the upper and lower blades in the direction of separation from each other, allowing the nail to be cut in the same way as a conventional nail clipper.

In addition, if an engaging protrusion is provided on the operating lever,
The joint between this engaging protrusion and the engaging protrusion on the upper blade body becomes the point of effort when pressing the operating lever.

[Example] Examples embodying the present invention will be described below.

A first embodiment of the present invention is shown in FIGS. 1-4. The upper blade body 7 and the lower blade body 8, which have the same width, are fixed to each other at their proximal ends (right end in FIG. 2), and their distal ends are held apart from each other. Cutting blades 9 are provided at the tips of the upper and lower blade bodies 7.8, respectively.

As shown in FIG. 3, on the upper surface of the front end of the upper blade body 7,
An engagement protrusion 11 as an engagement protrusion extending in the width direction of the upper blade body 7 is provided in a protruding manner. This engagement protrusion 11 is formed by press working, and does not reach both ends of the upper blade body 7. A support pin 10 is rotatably inserted into the upper and lower blade bodies 7.8 at a position slightly forward of the engagement protrusion 11.

The support bottle 10 has a lower blade body 8 by a head at its lower end.
It is locked to. Further, the tip of the support bottle 10 projects upward from the upper blade body 7, and a support shaft 1 is attached to the projecting portion.
2, the base end of the operating lever 13 is attached so as to be rotatable in the vertical direction.

As shown in FIGS. 3 and 4, an engaging protrusion 14 and a recess 15 are simultaneously formed by press working on both the upper and lower surfaces of the base end of the operating lever 13.
It extends in the width direction, but does not reach both ends. The recess 15 is located at a location corresponding to the engagement protrusion 11 on the upper blade body 7 when the operating lever 13 is placed face down on the upper blade body 7, and the engagement protrusion 11 can be accommodated therein. It is formed like this. The engagement protrusion 14 is formed with a relatively low protrusion height.

The engagement protrusion 11 on the upper blade body 7 is arranged so that when the nail clipper is in use, as shown in FIG. This is the point of emphasis F.

The method of using the nail clipper of this embodiment is almost the same as that of the conventional nail clipper shown in FIG. That is, when using
First, from the unused state shown in FIG.
Make it 2. And the operating lever 1 is centered around the support bin 10.
3 by 180 degrees and then tilted toward the upper surface of the upper blade body 7 to be in the operating state as shown in FIG. When the operating lever 13 is pressed in the direction of the arrow R, the cutting blade 9 is closed and the nail can be cut.

The features of this embodiment will be described below.

First of all, when not in use, as shown in FIG.
Since the protruding height of the engaging protrusion 11 is low, the height of the front end of the nail clipper can be made lower than that of conventional nail clippers so that the front end of the nail clipper does not become bulky. Also,
In this state, when the operating lever 13 is laid down on the upper blade body 7, the engagement protrusion 11 enters the recess 15, so that the operating lever 13 is aligned in the longitudinal direction on the upper blade body 7 without shifting laterally. can be superimposed.

On the other hand, when using the nail clipper, the engagement protrusion 11 of the upper blade body 7 and the engagement protrusion 14 of the operating lever 13 are in contact with each other. Even if the height is lower than the conventional one, a sufficiently large inclination angle of the operating lever 13 can be ensured as shown in FIG. Therefore, it does not become difficult to use because the protruding height of the engaging protrusion 14 is reduced.

Furthermore, when using the nail clipper, two engaging protrusions 11.1
4 is the point of force F when pressing the operating lever 13,
These all extend in the width direction of the blade body 7.8 and are in contact with each other over a wide range. Therefore, even if the operating lever 13 is not completely aligned in the longitudinal direction of the blade body 7.8 at the time of pressing, the engaging protrusion 11.14 can be pressed stably without coming undone.

In the first embodiment, the engagement protrusion 14 may not be provided protrudingly on the operating lever 13, and this is considered as a different example in the fifth embodiment.
It is shown in Figure 6. In this example, the upper surface of the operating lever 13 is formed as a smooth surface with no unevenness, and other aspects are the same as in the first embodiment.

In this case, the height of the front end of the nail clipper can be made even lower than that of the nail clipper of the first embodiment since there is no protrusion on the upper surface of the operating lever.

Next, a second example of the engagement protrusion of the upper blade body and the engagement protrusion of the operating lever will be described. A third example is shown below.

In the second embodiment shown in FIG. 7, an engagement protrusion 17 is formed at the front end of the upper blade body 16 as an engagement protrusion extending over the entire width direction of the upper blade body 16. Operation lever 1
An engaging protrusion 19 and a recess 20 are simultaneously formed on the upper and lower surfaces of the proximal end portion of 8 by press working. All of these extend over the entire width direction of the operating lever 18, and the recess 20 has a groove shape. In this embodiment as well, when the nail clipper is not in use, the engagement protrusion 17 enters into the recess 20, allowing the operating lever 18 to be superimposed on the upper blade body 16.

This embodiment has engagement protrusions 17 and 19 compared to the first embodiment.
Another advantage is that the concave portion 20 can be easily formed mechanically.

In the third embodiment shown in FIG. 8.9, the upper blade body 31
An engagement protrusion 32 serving as an engagement protrusion is formed in a circular planar shape at the front end of the holder. Further, on the upper surface of the base end of the operation lever 33, an engagement protrusion 34 as an engagement protrusion is formed in a planar circular shape, and on the lower surface of the base end, an engagement protrusion 32 is formed as shown in FIG.
A recessed portion 35 corresponding to this is formed.

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

The engagement protrusion that forms the point of force when pressing the operating lever is provided on the upper blade body, and when the nail clipper is not in use, the engagement protrusion can be stored in the recess on the lower surface of the operating lever, so that the front end of the nail clipper It is possible to reduce the overall height of the device so that it does not become bulky.

An engagement protrusion is also provided on the top surface of the operation lever, and the nail clipper is used with this engagement protrusion and the engagement protrusion on the upper blade in contact with each other, so the engagement protrusion on the operation lever Even if the protruding height of the part is relatively low, it is possible to ensure an easy-to-use opening between the operating lever and the upper blade.
