Abstract

PROBLEM TO BE SOLVED: To allow even a handicapped person with one hand feeble by a method wherein nails are inserted between upper and lower blades and the blades are vertically moved automatically by a switching action to perform a cutting operation. SOLUTION: This automatically nail clipping device is provided with a nail cutting part 1 comprising an upper blade 1a and a lower blade 1b, a pressing means 2 which performs a nail cutting operation by pressing the upper blade 1a, a driving means 3 to drive the pressing means 2 and a switching means 4 for actuating the driving means 3. Any form is possible for the pressing means 2 only if nails can be cut by pressing down the upper blade. The driving means 3 for driving the pressing means 2 employs a driver such as an electric motor or a cylinder device. The lower blade 1b is provided with a pressure sensing sensor 5, which 5 is connected to a switching means 4. When a position where a nail is carried on the lower blade 1b and cut is decided, a pressure on the lower blade 1b by the nail is detected and the driving means 3 is operated to cut the nail through the switching means 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nail clipper, and more particularly, to automatically perform a nail clip operation so that a nail can be easily clipped even when one hand cannot be used. In particular, the present invention relates to an automatic nail clipper that is convenient for people with physical disabilities.

[0002]

2. Description of the Related Art A general nail clipper comprises a pair of blades, an upper blade and a lower blade, and a lever for pressing the upper blade to cut the nails. It is cut.

[0003]

However, it is not easy or impossible for a handicapped person, for example, who has a hand with one hand to cut the nail of his hand.

An object of the present invention is to provide an automatic nail clipper capable of cutting a nail with only one hand even when one hand cannot be used.

[0005]

In order to achieve the above object, in the present invention, a nail clipper composed of an upper blade and a lower blade,
An automatic nail clipper comprising: a pressing means for pressing an upper blade to cut a nail; a driving means for driving the pressing means; and a switch means for operating the driving means. provide.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a preferred embodiment,
It is characterized in that a sensor for detecting that the claw is at the cutting position is provided and the sensor is connected to the switch means.

In another preferred embodiment, a base for holding a nail clipper comprising the nail clipper and pressing means is provided, the drive means is attached to the base, and the nail clipper is attached to the drive means. The nail cutting tool is configured to be engaged with the pressing means of the tool, and the nail cutting tool can be attached to and detached from the base.

1 is a schematic diagram showing the basic structure of the present invention. This automatic nail clipper comprises a nail clipper 1 including an upper blade 1a and a lower blade 1b, a pressing means 2 for pressing the upper blade 1a to perform a nail cutting operation, and for driving the pressing means 2. Drive means 3 and switch means 4 for operating the drive means 3. The pressing means 2 may be a lever type like a normal nail clipper, or any other type as long as it can push down the upper blade to cut the nail. The driving means 3 for driving the pressing means 2 can drive the pressing means 2 up and down by using an electric motor, a cylinder device or another type of driving device.

A pressure sensor 5 is provided on the lower blade 1b. The pressure-sensitive sensor 5 is connected to the switch means 4, detects the pressure applied to the lower blade 1b by the claw when the position where the claw is placed on the lower blade 1a and cut is determined, and the pressure sensor 5 detects The claw is cut by operating the driving means 3. This pressure-sensitive sensor 5 includes a lower blade 1 formed by the tip of a finger.
The pressure on b may be detected, or the position of the nail may be detected by an optical sensor or the like. Alternatively, a claw or finger stopper 21 may be provided at an appropriate position as a safety device, and this stopper may be used as a switch. The position of the stopper 21 is preferably adjustable.

It is desirable that the drive means 3 is further connected to the second switch means 6 at the hand or foot. The second switch means 6 is composed of a switch such as a push button switch which is easy to operate, and when the position where the nail is cut is determined, the nail cutting operation can be started by operating the elbow or foot of the hand. .

FIG. 2 shows a more specific configuration example of the embodiment of the present invention. In this example, an automatic nail clipper is configured by detachably mounting a commercially available nail clipper 20 including a nail clipper 1 including an upper blade and a lower blade and a lever-type pressing means 2.

The nail clipper 1 of the nail clipper 20 is fixedly held on the base 12 by screwing or other fixing means or an appropriate clamp means. The rotary cam 9 is attached above the base 12. The rotary cam 9 presses and drives the pressing plate 13 via the sliding contact plate 10 and the spring 11. The lower surface of the pressing plate 13 engages with the upper end of the lever lever (pressing means 2) of the nail clipper 20. The rotary cam 9 is rotationally driven by the motor 14. When the rotating cam 9 rotates from the state shown in the figure as shown by the arrow, the pressing plate 13 descends, depresses the lever lever 2, and cuts the claw.

The spring 11 is for keeping the nail cutting pressure constant. The spring may be omitted by allowing the cam shape and the height of the pressing plate 13 to be constantly adjusted with respect to the nail clipper. The nail clipper 20 is attachable to and detachable from the base 12, and a commercially available nail clipper can be replaced and attached. In this case, it is desirable that the pressing plate that presses the lever of the nail clipper be adjustable in height so that it can be used with nail clippers of various shapes and sizes.

A pressure sensor 5 is provided at the tip of the base 12 in correspondence with the position of the lower blade 1b of the nail clipper 20. This pressure-sensitive sensor 5, when placed at the position where the nail is cut,
As described above, this is detected and the motor 14 is driven via the switch 15. It is desirable that the switch 15 is configured not only to be operated by the pressure-sensitive sensor 5 but also to be operated manually or by stepping as described above. Instead of or in addition to the pressure sensor 5, a nail or finger stopper 21 is provided as a nail or finger safety device.
May be provided at an appropriate position with a position-adjustable structure, and the switch 15 may be operated by the stopper 21.

In the above embodiment, the position of the nail is detected via the pressure sensor and the nail cutting operation is performed based on the detected position. However, only the hand or foot switch is provided without using the sensor. Alternatively, when the position of the nail is determined, the switch of the hand or the foot may be operated to perform the nail cutting operation. The vertical drive mechanism is not limited to the rotary cam connected to the motor, and any type of drive mechanism may be used.

[0016]

As described above, according to the present invention, by simply inserting the claw between the upper and lower blades, the blade is automatically moved up and down by the detection by the sensor or the switch operation to perform the nail cutting operation. Since it is performed, even a physically handicapped person with one hand disabled can cut the nail by himself.

Further, the driving means including the rotary cam, the motor, the spring, the pressing plate and the like and the switch for operating the driving means are constituted as an integral unit, and the nail clipper can be exchanged with the integral unit for use. The nature is enhanced.
