Illlll l vw mm [NVE/WUR. RICHARD L. URBUSH lll! .mm2 mm, mm,
United States Patent 3,316,576 ELECTRIC TOOTHBRUSH Richard L. Urbush, Racine, Wis., assignor to Scovill Manufacturing Company, Waterbury, Conn., a corporation of Connecticut Filed Aug. 19, 1965, Ser. No. 481,020 4 Claims. (Cl. 15-22) This invention relates to electric toothbrushes and more particularly to the brush handle holder which is part of the portable power actuated unit for a toothbrush or the like.
The main object of the invention is to provide a holder into which the handle of a toothbrush or the like can be inserted by a simple pushing motion and withdrawn by merely pulling the brush handle out of the holder without manipulation of any of the holder parts.
Another object is to provide a holder which is self adjustable to receive brush handles of different sizes and shapes and to retain the handles by friction.
Another object is to provide a brush handle holder and means for mounting it in a portable power actuated unit in such manner that moisture is prevented from entering the unit between the holder and the unit casing.
The objects and advantages of the invention will be apparent from the drawings and following description.
In the drawings:
FIG. 1 is a longitudinal vertical sectional view, partly in elevation, of a portable power actuated unit for a toothbrush or the like embodying my invention.
FIG. 2 is a longitudinal vertical sectional view, on an enlarged scale, of the brush handle holder and part of the housing in which it is mounted.
FIG. 3 is a transverse vertical sectional view, on an enlarged scale, in the plane of the line 3 3 of FIG. 1.
In that embodiment of the invention shown in the drawings, the power actuated unit comprises a generally cylindrical casing consisting of an end member 11, intermediate portion 12 having a reduced diameter forward end 13, and a front end casing 14 provided with a central opening 15. The reduced diameter end portion 13 of the the casing 12 is slightly smaller in external diameter than the internal diameter of the front end casing 14 which is retained on the part 13 by a flange 16 engaged in the groove :formed by the projection 17 on the member 13 adjacent its junction with the casing 12.
A conventional toothbrush, shown in FIG. l, comprises the `bristle mounting 18, bristles 19 and handle 20;
The holder for receiving and frictionally holding the brush handle 20 comprises a holder housing 21 cylindrical in form with closed end 22 provided with lan apertured tongue 23, the opposite end being open and provided with external screw threads 24 or other means for holding brush handle clamping means adjacent said open end. Brush handle clamping means located in the holder housing 21 comprises a pair of clamping bars 25 generally rectangular .in cross section, their proximate surfaces being parallel to each other and nearly contacting as sho-wn in FIGS. 1 and 3 when not spaced apart by insertion of a brush handle. The forward ends of the proximate faces of the clamping bars 25 are beveled as indicated at 26 to facilitate placement of a handle 20 between the bars. yPreferably the housing 21 and clamping bars 25 are made of plastic materials, such for example, as Delrin Each clamping bar 25 has attached to its outer side surface a leaf spring 27 having a ilat central portion provided With two apertures, a rearward free end 28 and a forward portion 29 with end hook 30. Each spring 27 is attached to a clamping bar 25 by two rivets 31 counter- 3,3 16,5176 Patented May 2, 1967 sunk at 32 on the proximate sides of the clamping bars 25. The - free ends 28 and 30 of the springs 27 are biased to extend outwardly from the flat portion 27 in divergent directions. The two units are held together by an O-ring 33 located in grooves formed in the outer faces of the clamping bars. Two at pieces of plastic material 34, as long as the bars 25 and as wide as the thickness of the two bars 25 contacting each other, are placed adjacent opposite side edges of the bars to keep them in line. These flat pieces 34 are also held in place by the O-rings 33. The outer surfaces of the parts 28 of the springs 27 bear a-gainst the inner surfaces of the holder housing 21 to urge the clamping bars 25 toward each other. The parts 29 likewise bear on the inner sur-faces of the holder housing 21 to urge the bars 25 toward each other, and the hook ends 30 extend over and engage notches in the open end edge of the housing 21 adjacent the screw threads 24.
After the clamping bars 25 with attached springs 27, side pieces 34 and O-rings 33 have been assembled and placed in the holder housing 21, the assembly is placed in the casing 12 and mounted therein by the following described means: ball bearings 35 in grooves formed in `buttress 36 on the casing 12 and buttress 37 on housing 21; and a sealing sleeve 38 of flexible or other suitable material shaped to engage the forward end edge of the member 13 of casing 12 and to extend over the space between the member 13 and the holder housing 21. After mounting said parts in the casing 12, a cap 39 is screwed on the threads 24, or snapped on, thereby clamping the sleeve 3S between the cap 39 and holder housing 21. Finally the front end casing 14 is snapped into place on the casing 12-13.
The holder housing 21 and contents are given an 1000 orbital reciprocatory movement by any suitable means, such as the mechanism shown which comprises a rotated shaft 40, pinion 41, gear 42 with eccentric shaft 43 which extends through the round hole in the tongue 23. The shaft 40 may 4be driven by a motor (not shown). A switch 44 controls the motor.
The brush handle 20 can be inserted between the clamping bars 2S with the bristles facing in one direction or in the opposite direction. The clamping bars automatically return to the position shown in FIG. 1 when the brush handle is withdrawn. Moisture cannot enter between the outer casing and the brush holder housing. The construction of the housing 21 and clamping assembly is such that moisture which may enter therein is harmless and readily eliminated.
Changes may be made in details of construction and in the form and arrangement of parts without departing from the scope of the invention as defined by the appended claims.
