Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wax applicator for uniformly applying wax to the surface of an automobile body or the like.

(B) Prior art Wax has a role to protect the paint applied to the body of a car and to give a beautiful luster.

Therefore, it is necessary to apply the wax uniformly and thinly and uniformly from the economical viewpoint. Work is inefficient.

Therefore, conventionally, as described in Japanese Utility Model Laid-Open No. 60-119973, an electric wax applicator using a pad that is eccentrically rotated by a drive motor is known.

C Problems to be solved by the present invention Since the conventional wax applicator rotates the pad eccentrically (revolves around the motor shaft), the wax scatters around due to the centrifugal force generated by the rotation of the pad. Would.

In addition, the eccentric rotation of the pad generates a self-propelling force, and an arc-shaped unevenness rubbed with a sponge remains on the application surface, so that it is difficult to control the application to be thin and uniform.

The disadvantage can be solved by connecting the pad to the housing so as not to rotate, but when connecting the pad to the housing, the transmission balance of the eccentric rotational force is lost if the pad is not evenly mounted and supported. Will cause flapping.

However, if the connection is made at a plurality of locations, not only is it difficult for the pad to move freely, but also the structure becomes complicated and assembly becomes difficult.

D. Means for Solving the Problems The present invention is a wax applicator capable of imparting the same movement to a pad as a manual operation, and has a structure including a housing having a built-in drive motor and an exposed surface on one surface of the housing. A pad, a resilient pad support member interposed between the pad and the housing, a crank member having a slight eccentric width fixed to the rotating shaft of the drive motor, and a concave A waxing machine provided with a bearing portion for rotatably holding an eccentric portion of a crank member, wherein the pad support member has a connecting leg having means for coupling to both the pad and the housing. And a supporting leg having a means for coupling to only one of them.

E. The pad is a housing having a pad supporting member having elasticity and having a connecting leg having means for coupling to both, and a supporting leg having means for coupling to only one of them. Because it is connected and supported, it can not rotate, but it is in a state where it can move freely along the plane orthogonal to the rotation axis, so when receiving the eccentric rotational force of the crank member,
A motion describing a circular orbit centered on the rotation axis of the motor, that is, a fine vibration along a circular locus whose radius is the eccentric width of the crank member.

F Example An embodiment of the wax applicator according to the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a housing in which a pad cover 1b is integrally formed under a flat egg-shaped grip 1a which can be held by a palm,
The housing 1 has a structure that can be divided into two parts by removing set screws 2, 2,....

In the grip 1a of the housing 1, the grip 1a
A flange 4 surrounding the outer periphery of the body of the driving motor 3 housed therein is provided, and a partition plate 5 for dividing an internal space is integrally formed at a boundary between the grip portion 1a and the pad cover portion 1b. The partition plate 5 has an insertion hole 6 in the center, into which the bearing 3a of the motor 3 is inserted.
Fitting holes 8, 8 for fitting and connecting the tips of rubber connecting legs 7, 7 as support members are provided at front and rear portions of the through hole 6.
Are provided respectively.

The insertion hole 6 and the fitting hole 8 are formed in half so as to be symmetrical with respect to the division surface of the partition plate 5, and the division surface has a screw hole 9 for the set screw 2 and a screw insertion hole in the plate surface. 9 '
Are provided respectively.

On the front and rear portions of the partition plate 5, concave recesses 11, 11 are provided on the side opposite to the grip portion 1a, into which support support legs 10, 10 as pad support members are fitted and connected.

The concave portion 11 has a cross section in which the opposite surface of the circle is cut off, and the base end portion 10 of the corresponding supporting leg is cut off.
a Shape matches.

On the other hand, the distal end portion 10b of the support leg has a larger diameter than the base end portion 10a, and the central portion of the distal end surface is depressed.

In addition, a switch mounting window 13 for sandwiching and supporting the switch 12 and a cord pull-out window 15 for pulling out the cord 14 are cut out at front and rear portions of the grip portion 1a.

A socket 14a for obtaining power from a cigar lighter of the vehicle is attached to a leading end of the cord 14, and the cord 14 is electrically connected to the switch 12 and the motor in the housing 1.

Reference numeral 16 denotes a disc-shaped pad. Fitting holes 17 and 17 for fitting the base end of the connecting leg 7 into the front and rear portions corresponding to the connecting leg 7 are provided in the pad 16, respectively. The fitting hole 17 is provided with a step at an intermediate portion, and the front side exposed outside the housing is large, and the opposite back side is narrow.

As a result, if the connecting leg 7 is inserted from the front side, the large diameter portion at the base end of the connecting leg 7 is prevented from coming off.

A hook-and-loop fastener 18 is adhered to the front side of the pad 16 on one side, and a bearing 19 is fixed to the center of the back side.

The motor 3 and the pad 16 are assembled in the housing 1 thus formed in the following manner.

In the motor 3, a rubber ring body 20 is externally fitted to the body, the ring body 20 is fitted into a concave groove 4 a formed on the inner periphery of the flange 4, and the bearing of the rotating shaft projection is inserted into the insertion hole 6. It is fixed in the grip portion 1a by inserting the portion 3a.

A crank member 21 eccentric about 0.5 mm is attached to the end of the rotating shaft of the motor.
21 is provided with a disk-shaped balancer 22.

The distal end of the eccentric shaft 21a of the crank member 21 is inserted and supported by a bearing 19 of a pad 16, and the pad 16 is attached to the partition plate 5 of the housing while being connected to the partition plate 5 by a connecting leg 7, and is vibrated freely by the supporting leg 10. Supported by

One end of the connecting leg 7 is connected to the fitting hole 17 of the pad 16, and the other end is fitted into the fitting hole 17 so as to be sandwiched by the divided partition plate 5 with respect to the partition plate 5. In addition, since the support leg 10 is connected to be fitted only to the partition plate 5, the assembly of the pad support member is simplified, and there is no need for a member for fixing the support leg 10. In addition, costs can be reduced.

Furthermore, the supporting leg 10 has a shape in which the cross section of the concave portion 11 has a shape obtained by cutting off the facing surface of a circle, and the base end portion 10a corresponding thereto is fitted therein, so that it does not rotate or shift due to vibration. When assembling the pad 16, the support leg 10 is prevented from bending even when pressed by the recessed portion of the distal end surface.

Since the pad 16 is uniformly connected and supported by the connecting leg 7 and the supporting leg 10 interposed between the housing 1 and the connecting leg 7, the pad 16 is prevented from rotating and flapping up and down. Is suppressed.

A rubber bumper 23 for protecting the vehicle body is mounted around the pad cover 1b.

The wax applicator thus formed is used in a state where the sponge 24 is attached to the exposed surface fastener 18 of the pad 16 using the surface fastener 25 attached to one surface of the sponge 24. .

On the eccentric shaft side of the crank member 21, the rotational motion of the motor is converted into a circular locus motion about the rotary shaft, so that the pad 16 elastically supported by the housing has the eccentric width of the crank member as a radius. It only makes small vibrations along the circumferential trajectory but does not rotate.

As a result, the sponge 24 can be finely vibrated integrally with the pad 16 so that the wax can be applied evenly. Thus, the movement of the portion in contact with the application surface is suppressed, so that an excessive application force does not act, and the application force is kept constant even if the pressing strength changes.

The number and arrangement of the connecting legs and the supporting legs and the eccentric width of the crank member can be changed as appropriate, and are not limited to the embodiments.

According to the present invention, the pad is supported by the housing by the pad supporting member including the elastic connecting leg and the supporting leg, so that the pad is easily assembled and the pad supported by the pad supporting member is provided. Is connected by the connecting legs, so it does not rotate even if it receives the rotational force of the crank member, it only vibrates.It is easy to use because the fluttering is suppressed by being supported by the supporting legs. There is no danger of scattering.

By a motion very close to a manual operation, a uniform application force due to a uniform circular locus vibration always acts on the body irrespective of the pressing force, and the body can be applied thinly and uniformly without causing uneven coating.
