DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention relates to an electric nail polisher that performs nail polishing by reciprocatingly driving a polishing member.

[Prior art]

Conventionally, as an electric nail polisher, a type in which a polishing member is rotated is provided.In the case of this rotary type, when the rotating polishing member is pressed against the nail to perform nail polishing, the nail is In addition to being slippery, the polishing member easily escapes from the intended location on the surface of the nail and has the disadvantage that it is not possible to perform nail polishing as desired. Difficult to polish parts. In view of these points, the one shown in U.S. Pat. No. 3,240,966 or Japanese Utility Model Publication No. 40-27070, that is, the one in which the polishing member is reciprocally driven, is easy to nail polish.

[Problems to be solved by the invention]

However, among the reciprocating electric nail polishers, the former is difficult to use because the polishing member is supported by the cantilever, and when the polishing member is pressed against the nail, deflection occurs. Met. In the latter, since the main body case has a surface that receives the sliding of the polishing member, the polishing member does not bend, but the sliding load is large,
This is a major problem in battery-powered systems. The present invention has been made in view of such a point, and an object of the present invention is to provide an electric nail polisher that does not cause a problem in terms of deflection and sliding load while being a reciprocating type. is there.

[Means for Solving the Problems]

Thus, the present invention provides an electric nail polisher including a split main body case accommodating a driving member, and a movable plate having a polishing member mounted on one surface of the main body case and driven reciprocally by the driving member. A feature is that a metal fixing plate having a sliding receiving surface of the movable plate and a connecting portion of the split main body case is provided on a mounting surface of the movable plate in the main body case. I have. [Operation] According to the present invention, since the movable plate slides on the metal fixed plate that is arranged on the mounting surface of the movable plate and connects the two main body cases, the movable plate may bend. Of course, there is no sliding resistance. [Embodiment] Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. The main case 1 of this electric nail polish machine has a thin left and right thickness and a smooth upper portion of a front end face. A switch handle 5 is provided on the curved surface, and a grip portion 10 having a battery housing inside projects integrally from the rear end surface toward the rear, and is formed on the lower end surface. The movable plate 2 is disposed, and the attachment 3 on which the polishing member 30 is mounted is detachable on the lower surface side of the movable plate 2. In the figure, reference numeral 8 denotes a battery cover. As shown in FIG. 5, in the main body case 1, a motor 4 whose axial direction is the vertical direction, a pinion 41 attached to an output shaft of the motor 4, and supported by an intermediate shaft 42 to mesh with the pinion 41 A driving member including a gear 43 and an eccentric pin 44 formed integrally with the gear 43 is housed,
A switch plate 55 connected to the leg 50 of the switch handle 5 and sliding in conjunction therewith;
And a movable contact plate 62 which is pressed toward the fixed contact plate 61 by a projection 56 protruding from the movable contact plate 62. In the figure, reference numeral 11 denotes a motor mount. A metal fixing plate 15 is attached to the lower end surface of the main body case 1 facing the eccentric pin 44, and the movable plate 2 is arranged on the lower surface side of the fixing plate 15. Above, fixed plate 15
As shown in FIG. 4, both sides have a projection 16 and a hook 18 which are respectively inserted into engagement grooves 12 of the left and right portions of the main body case 1 which are formed in two right and left parts. A projecting piece 17 inserted into a groove 13 extending over both right and left portions of the main body case 1;
When the main body case 1 is attached to the main body case 1, the protrusions 16 separate the main body case 1, generate a gap, and use the main body case 1 in use.
The generation of vibration and chatter noise is prevented, and the protrusion 17 prevents displacement in the front-rear direction. The movable plate 2 has a hook 20 that is inserted into the engaging groove 12 of the main body case 1, and the hook 20 extends in the longitudinal direction of the engaging groove 12.
20 is movable, so that it is movable in the longitudinal direction of the lower end surface of the main body case 1, that is, in the front-rear direction, and has a peripheral wall 21 integrally protruding downward from the peripheral edge of the lower surface. A holding plate 25 is disposed on the lower surface side surrounded by the peripheral wall 21. The holding plate 25 has an insertion piece 26 that is inserted into the engagement groove 12 of the main body case 1 and prevents the hook 20 of the movable plate 2 from bending. A left-right groove provided on the upper surface of the movable plate 2
Since the eccentric pin 44 is engaged with the motor 22,
When the eccentric pin 44 is rotated by the
A reciprocating motion in the front-rear direction guided by a guide groove 19 formed on the upper surface and a guide protrusion 23 projecting from the upper surface and engaging with the guide groove 19 is performed. On the upper surface side of the movable plate 2, as shown in FIG. 7, a ridge 24 long in the direction of movement is formed, and the ridge 24 comes into sliding contact with the fixed plate 15. Fixed plate
Because 15 is made of metal and has a small sliding contact area,
The sliding resistance between the fixed plate 15 and the movable plate 2 is small. The polishing member 30 is provided as being fixed to one surface of the attachment 3 as described above, and is mounted on the lower surface side of the movable plate 2 so as to be fitted into the peripheral wall 21.
At this time, the notch 28 is formed in a part of the peripheral wall 21 of the movable plate 2, and the knob 31 that is located in the notch 28 is provided on the attachment 3 side.
The attachment 3 can be easily attached to and detached from the movable plate 2. A plurality of attachments 3 having different roughness of the polishing member 30 are prepared, and these can be used properly. In this electric nail polisher, if the upper side of the main body case 1 is gripped so as to be in the palm of the hand, the fingers come into contact with the finger contact surfaces 14, 14 on both sides of the main body case 1, and in this state, When the switch handle 5 is operated, the movable plate 2 and the attachment 3 attached to the movable plate 2 are reciprocally driven as described above, and the nail is brought into contact with the polishing member 30 of the attachment 3 by touching the nail. Can be polished. At this time, the reaction force when the polishing member 30 is applied to the nail acts between the movable plate 2 and the fixed plate 15, but the frictional resistance between the two is originally small, so that the force of the motor 4 is small. In both cases, there is no problem in driving the movable plate 2.

【The invention's effect】

As described above, in the present invention, since the movable plate slides on the metal fixed plate that is arranged on the mounting surface of the movable plate and connects the two main body cases, the movable plate may bend. Needless to say, the sliding resistance can be reduced and the load can be reduced, and the sliding operation of the main body case side can be eliminated, so that a light operation can be obtained.
