US 5,206,967 A · Electric wax applicator

Abstract

An electric wax applicator comprises a housing, a pad defining a bottom portion of the housing, a sponge removably joined to a lower surface of the pad, an electric motor provided in the housing and having a drive shaft, a crank member connected to the drive shaft and including a balancer portion and an eccentric shaft portion which has a center deviated slightly from an axis of rotation of the drive shaft and is rotatably received in a bearing of the pad, and a pad support of resilient material located between an inner horizontal partition wall of the housing and the pad. The pad support may include first supporting members joined both to the pad and to the partition wall of the housing and second supporting members joined only to either of the pad and the partition wall of the housing. When the wax applicator is switched on, the crank member rotates together with the drive shaft. While the crank member is rotating, the eccentric shaft portion thereof vibrates to cause the pad to vibrate in the plane in which the pad is located.

Dependent claims

In an electric wax applicator having

(a) a housing,
(b) a pad received in a bottom portion of the housing,
(c) a sponge removably and replaceably joined to a lower surface of the pad,
(d) an electric motor mounted in the housing and having a drive shaft,
(e) a crank member connected to the drive shaft and including a balancer portion and an eccentric shaft portion having a center deviated slightly from the axis of rotation of the drive shaft and rotatably received in a bearing of the pad,
the improvement comprising pad supporting means of resilient material secured between the housing and the pad, said pad supporting means including
A. first resilient supporting members joined both to the pad and to the housing for mountingly securing the pad to the housing, said first members being so joined by seating in apertures in the pad and in the housing, and
B. second resilient supporting members joined, by seating in apertures, to only one of the pad and the housing and in contact with the other, said second members being spaced from said first members and resisting movement of said pad relative to said housing along a direction parallel to said drive shaft.

In a hand-held electric wax applicator having

(a) a housing having a pad-receiving bottom portion,
(b) a pad received in said housing,
(c) an electric motor provided in the housing and having a drive shaft and a bearing portion,
(d) crank member connected to the drive shaft and having a shaft portion rotatably received in a bearing of said pad, and
(e) the shaft portion having a center deviated slightly from the axis of rotation of the drive shaft, so that when the crank member is rotated by the drive shaft, every point on the shaft portion describes a circle with a radius corresponding to the amount of deviation of the center of the shaft portion from the axis of rotation of the drive shaft, thereby causing the pad to vibrate relative to the housing in a direction perpendicular to the axis of rotation of the drive shaft,
the improvement comprising
A. means forming second openings in said pad,
B. first and second shells constituting said housing when coupled together,
(i) each said shell having and inner recessed base portion with a middle semicircular cut and two side semicircular cuts aligned on either side of said middle semicircular cut along an imaginary line that extends through the axis of said middle semicircular cut,
(ii) the middle semicircular cuts of said shells defining a central opening in said base portion of said housing, and said side semicircular cuts of said shells defining first openings in said base portion of said housing,
(iii) said bearing portion of said motor being concentric with said central opening, and
C. first pad supporting members,
(i) each said first pad supporting members having a recessed portion removably and replacedly seated in one of said side openings for seating that first member in said first openings,
(ii) said first pad supporting member being fixed to said pad by being seated in said second openings,
(iii) said first pad supporting members being coupled between said pad and said housing for mounting said pad to said housing, and being resilient and allowing said pad to vibrate in a direction perpendicular to the axis of rotation of the drive shaft and preventing said pad from rotating relative to said housing, and
(iv) said first pad supporting members providing the sole mounting of said pad to said housing.
