Description

The present invention relates to an automatic nail grinder.

Recently, oriental medicine such as acupuncture, acupuncture and massage is gaining attention in the West.
The nail growth massage targeted by the present invention stimulates the acupuncture points (wells) at the position of the nail line (nail, fistula, and finger pressure) to improve autonomic nerves and increase body immunity. It is said that it can be expected to have a remarkable therapeutic effect on various symptoms of the body, and it is said that the effect can be expected to maintain health.
In general, when practicing nail fisting by hand, the nail of the finger that is pressed with the thumb and forefinger is pinched, but the finger is tired and it is difficult to effectively apply the finger pressure.
Therefore, as a fingertip stimulation method using a machine, Evo Inc. filed an invention related to a fingertip stimulation device that irradiates near-infrared rays at the nail line (JP 2006-166959, JP 2007-159684, JP 2007-7449), It was commercialized as the world's first nail massage robot “Warming Ru”. There are also a method of applying stimulation by pinching a finger with an instrument similar to a plier (Japanese Patent Application Laid-Open No. 2007-125335) and a method using a slightly complicated link mechanism (Japanese Patent Application Laid-Open No. 2006-181178). Because the pliers method is easy, it is marketed as “Mitaro Tsujimi” designed by the instructor of Tokyo Women's Medical University.

As described above, it is cumbersome to implement the technique, and it is difficult to automatically nail it with a commercial product of a complicated link system or a simple plier system.
Since the present invention arranges the function of the autonomic nerve in the medical welfare field as described above, even if a finger having a different thickness is selected, an appropriate gap is selected and a physical stimulus is effectively applied to the hairline of the nail just by inserting the finger there. It is intended to provide an automatic nail grinder having a simple structure that is automatically given automatically.

(1) The outer ring 100 and the inner ring 200 are arranged inside thereof, and a finger or a claw is inserted between the outer periphery of the outer ring 100 and the outer periphery of the inner ring 200,
An eccentric tilting disc 300 which is mounted in the inner ring so as to be rotatable along the inner periphery thereof, and is eccentrically and tilted and fixedly connected to a rotating shaft 400 having an axis 401 positioned inside the outer ring. The automatic nail grinder is characterized in that the rotary shaft 400 fixed to the eccentric tilting disc 300 is mounted on the rotational drive geared motor 500.
(2) The elastic members 110 and 220 are disposed on the inner peripheral portion of the outer ring 100 and the outer peripheral portion of the inner ring 200, and the outer ring 100 is provided separately from the inner ring 200 without a connecting portion, and The automatic nail grinder has the second feature of elastically floating and supporting.

That is, according to the above configuration, the automatic nail grinder of the present invention performs a complicated three-dimensional operation in the outer ring of the floating support without rotating the inner ring by the three-dimensional rotation operation of the eccentric tilting disc. Because it can be tightened, the nails and fingers can be safely and easily inserted between the inner and outer rings that do not rotate, regardless of their thickness, etc. By rotating the tilting disk, the three-dimensional pressing and squeezing operation of the inner ring is automatically performed, so that physical stimulation can be effectively applied.
Therefore, since the nail is not moved suddenly, an excessive force is not applied to the finger or the like, and the finger muscle, muscle or bone is not damaged. In addition, since an excessive load is not applied to the motor, the device itself is not damaged.
Furthermore, the automatic nail grinder of the present invention sets the relative relationship between the inner diameter of the outer ring and the outer diameter of the inner ring and the rotation center position of the eccentric tilting disc to an arbitrary relationship position inside the outer ring, The change pattern of the gap relationship formed by the inner peripheral surface of the outer ring that floats elastically and the outer peripheral surface of the inner ring can be changed to a desired one. Further, the degree of eccentricity and the degree of inclination of the eccentrically tilting disk, and further the rotational speed of the rotary shaft can be arbitrarily adjusted. By these, it has the flexibility which can change the strength and speed of the above-mentioned automatic physical stimulation freely.
Furthermore, since the automatic nail grinder of the present invention has a simple and compact structure, it is easy to manufacture, can be carried, and can easily carry out nail-plunging acupressure immediately and easily to anyone at any time. is there.

The best mode of the automatic nail grinder of the present invention will be described in more detail in Example 1 below.

1 to 3 show an embodiment of the present invention.
The automatic claw grinder in this example has an outer ring 100 and an inner ring 200 freely arranged inside, an eccentric tilting disc 300 is mounted in the inner ring 200, and the rotary shaft 400 is connected and fixed to the eccentric tilting disc 300. The rotary shaft 400 is mounted on the rotary drive geared motor 500.
The outer ring 100 is provided independently of the inner ring 200 without a connecting portion, and is attached and supported on the base 600 so as to be elastically floatable by a rubber belt 700.
The eccentric tilting disc 300 is eccentrically and tilted and fixedly connected to a rotating shaft 400 supported rotatably by a bearing 410, and has an outer peripheral surface in the inner ring 200 along its inner periphery. Positioned and rotatably mounted.
The rotary shaft 400 has an axial core 401 positioned inside the outer ring 100.
Elastic members 110 and 220 are disposed on the inner periphery of the outer ring 100 and the outer periphery of the inner ring 200, respectively.
The elastic material 110 is arranged along the inner peripheral surface of the outer ring 100 as a continuous wavy protrusion or discontinuous protrusion, and the elastic material 220 is formed as a continuous wavy protrusion or discontinuous protrusion on the outer peripheral surface of the inner ring 200. It is arranged along and is designed to apply a strong pressing force locally to the finger portion at the nail. In addition, the protrusions of the elastic members 110 and 220 may be arranged so that they are not uniform in size and hardness and can be freely selected.
The gap pattern formed by the inner peripheral surface of the outer ring 100 in a stationary state and the outer peripheral surface of the inner ring 200 is supported in the radial direction as shown in the front view of FIG. Because of the irregular gap change pattern, the gap between the outer ring 100 and the inner ring 200 on the inner ring 200 can be inserted according to its thickness. Can be inserted.
After inserting the nail massager driven by the rotational drive geared motor 500, the outer ring 100 is provided separately from the inner ring 200 without a connecting portion, and is elastically supported by the rubber belt 700 on the base 600. Therefore, excessive force is not applied to the finger of the nail, etc., finger muscles, muscles or bones are not damaged, and an excessive load is not applied to the motor. It can be done very safely. Furthermore, since the inner ring 200 moves in a three-dimensionally complex manner such as up, down, left, right, back and forth by the rotation of the eccentric tilting disc 300, nail biting finger pressure can be practiced immediately and effectively.
That is, the rotation center axis of the eccentric tilting disc 300 is not only offset from the center of the eccentric tilting disc 300 but is also slightly tilted with respect to the axis 401 of the rotation shaft 400. Since the eccentric tilting disc 300 is fixed to the rotating shaft 400 with a set screw or the like, it rotates integrally with the rotating shaft 400. Therefore, when the rotating shaft 400 is rotated, the outer circumference of the eccentric tilting disc 300 is complicatedly touched, and the movement in the direction of pressing the finger due to the eccentricity (the movement in the vertical direction Y in FIG. 2) and the tilted attachment The movement of the finger in the direction of the bone axis (movement in the horizontal direction X in FIG. 2) can be performed simultaneously. On the other hand, by attaching the inner ring 200 with the rolling bearing 330 to the eccentric tilting disc 300, the rotational speed component in the circumferential direction of the eccentric tilting disc 300 from the complicated motion of the eccentric tilting disc 300 (FIG. 2). Then, only the speed perpendicular to the paper surface can be removed. Therefore, even if the finger is inserted into the gap, the fingertip can be effectively and smoothly pressed and stimulated without being rubbed in the rotational direction of the eccentric tilting disc 300.
The rotation drive geared motor 500 is started / stopped by the control unit 800, and the pressure stimulation time can be freely set by incorporating the timer 801, and the operation pattern that combines the rotation start / stop of the motor. Can be repeated as many times as the number of fingers to be pressed and stimulated. The user can easily press and stimulate all fingers by removing the finger that has been pressure-stimulated until the time when the motor 500 is stopped and replacing it with the finger that is to be pressure-stimulated next. The rotation speed of the motor 500 can also be changed by the speed setting unit 803 of the control unit 800.

Since the automatic nail grinder of the present invention has the above-described excellent effects, it can be easily used in medical institutions and general households.
