Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an electric nail polisher that polishes nails by driving a polishing member. [Conventional technology]

Conventionally, electric nail polishers have been provided that rotate the polishing member, but in the case of this rotary type, the rotating polisher is pressed against the nail and the polishing member is removed from a targeted location on the surface of the nail. This has the disadvantage that the nails tend to escape, making it impossible to polish the nails as desired.In addition, when the polishing member is disc-shaped, it is difficult to polish the narrow corners of the nails. From these points, what is shown in U.S. Patent No. 3,240,966 and Japanese Utility Model Publication No. 40-27070,
In other words, it is easier to polish nails if the polishing member is driven back and forth.

[Problem to be solved by the invention]

However, in the above-mentioned reciprocating electric nail polisher, the polishing member is arranged in the direction of the extension of the grip, and the polishing member is driven back and forth in the direction of the extension of the grip. The center of gravity and the grip are located far away from the hand that holds the grip, which causes a see-saw phenomenon centered on the grip during use, making it impossible to apply the abrasive member to the nail as desired, causing the nail to be abrasive. The force with which the members are pressed tends to be uneven, which still poses a problem in terms of usability, and the overall length is long, making it difficult to put into a small bag and inconvenient to carry. The present invention has been developed in view of these points, and its purpose is to provide an easy-to-use product that allows you to polish your nails as you wish by reliably pressing the polishing member against the desired location on your nails. , to provide an electric nail polisher with good portability.

[Means to solve the problem]

Therefore, the present invention includes a main body case housing a driving member;
The electric nail polisher is comprised of a polishing member that is reciprocally driven by the drive member, the top surface of which is held in the palm of the hand, and both left and right sides that serve as finger contact surfaces on which the fingers of the hand that grips the main body case are placed. On the lower end of the main case,
A polishing member is disposed that is reciprocally driven in a direction along the longitudinal direction of this end surface, and the main body case is characterized in that the thickness in the left and right direction of the portion below the finger contact surface is thinner. are doing. [Operation] According to the present invention, when the main body case is gripped and the finger is placed on the finger contact surface, the polishing member is reciprocated near the finger, and a force to press the polishing member against the nail is reliably applied. Since the abrasive member is located where it can be, the abrasive member can be reliably pressed to the desired position of the nail. [Example] The present invention will be described in detail below based on the illustrated example.The main body case 1 of this electric nail polisher has a flat shape with a thin left and right thickness, and a smooth upper part of the front end surface. The switch handle 5 is formed into a curved surface, and a switch handle 5 is disposed on this curved surface, and a grip portion 10 whose interior is a battery storage portion integrally protrudes rearward from the rear end surface, and a grip portion 10 whose interior is a battery storage portion is integrally protruded from the rear end surface. A movable plate 2 is disposed, and an attachment 3 to which a polishing member 30 is attached is detachably attached to the lower surface of the movable plate 2. 8 in the figure is a battery cover. As shown in FIG. 5, inside the main body case 1 is a motor 4 whose axial direction is vertical, a pinion 41 attached to the output shaft of the motor 4, and a pinion 41 supported by an intermediate shaft 42 and meshed with the pinion 41. A drive member consisting of a gear 43 and an eccentric pin 44 integrally formed with the gear 43 is housed, and a switch plate 55 is connected to the leg 50 of the switch handle 5 and slides in conjunction with the switch plate 55. A movable contact plate 62 is provided which is pressed toward the fixed contact plate 61 by a protrusion 56 projecting from the movable contact plate 62 . In the figure, 11 is a motor mounting base. As shown in FIGS. 8 and 9, the switch plate 55 has a pair of click springs 57 and 5 that engage with click protrusions 59 and 59 protruding from the inner surface of the main body case 1.
7, which provides a click when the switch handle 5 is slid. In the figure, 51 is a protrusion protruding from the leg 50. By intersecting the movable contact plate 62, the movable contact plate 62 Displacement during attachment is kept within the clearance between the protrusion 51 and the protrusion 51. Furthermore, when the switch plate 55 is assembled in the reverse direction, the root portion of the click spring 57 comes into contact with the click protrusion 59 to operate the switch plate 55 and the switch handle 5 in a sliding manner, as shown in FIG. In order to prevent this, installation errors can be determined by operating the switch handle 5 from the outside, and since the protrusion 56 is located away from the movable contact plate 62 at this time, There is no possibility that the movable contact plate 62 will be deformed. Furthermore, when attempting to assemble the switch plate 55 face down, the protrusion 56 hits the inner surface of the main body case 1, as shown in FIG. 11, making it impossible to assemble the switch plate 55. A metal fixed plate 15 is attached to the lower end surface of the main body case 1 facing the eccentric bin 44, and the movable plate 2

It also has protrusions 17 on both ends that are inserted into the levers 13 that span both the left and right parts of the main body case 1, and the protrusions 16 separate the main body case 1, create a gap, and prevent the main body case from being damaged during use. In addition to preventing the vibration and chatter noise of 1, the protruding piece 17 prevents displacement. The movable plate 2 has a hook 20 that is inserted into the engagement groove 12 of the main body case 1, and since the hook 20 is movable in the longitudinal direction of the engagement groove 12, the movable plate 2 has a hook 20 that is inserted into the engagement groove 12 of the main body case 1. It is movable in the front-back direction, and includes a peripheral wall 21 that integrally projects downward from the periphery of the lower surface, and a presser plate 25 is arranged on the lower surface side surrounded by the peripheral wall 21. There is. This presser plate 25 is
An insertion piece 26 is provided which is inserted into the engagement groove 12 of the main body case 1 to prevent the hook 20 of the movable plate 2 from being bent. If you do not remove the presser plate 25, the movable plate 2 will not come out, and you will not be able to remove the movable plate 2 without strengthening the hook 20, which will cause the problem of difficult disassembly. The movable plate 2 does not come off at the same time when the detachably attached attachment 3 is removed. A groove 2 in the left and right direction provided on the upper surface side of the movable plate 2
2, since the eccentric bin 44 is engaged, when the eccentric bin 44 is rotated by the motor 4, the movable plate 2 is protruded from the upper surface of the guide groove 19 formed in the fixed plate 15, and the movable plate 2 is connected to the guide groove 19 formed in the fixed plate 15. It performs a reciprocating motion in the back and forth direction guided by the guide protrusion 23 that engages with the groove 19. As shown in FIG. 7, on the upper surface side of the movable plate 2, a protrusion 24 that is long in the direction of movement is formed. The sliding resistance between the two is small. As described above, the polishing member 30 is provided as being fixed to one surface of the attachment 3, and is attached to the lower surface side of the movable plate 2 so as to be fitted into the peripheral wall 21. At this time, a notch 28 is formed in a part of the peripheral wall 21 of the movable plate 2, and a notch 28 is formed on the attachment 3 side.
