Flatt, 7561 Mackey, Overland Park, Kans. Filed Aug. 11, 1960, Ser. No. 49,059 4 Claims. (Cl. 74-48) This invention relates to electrically operated toothbrushes.
The principal objects of the present invention are; to provide a hand-held electrically operated toothbrush holder which imparts a reciprocatory motion to the brush in the direction of the intervals between the teeth and permitsthe brush to be directed to any region of the tooth structure; to provide such a device which includes a novel mechanical linkage for translating rotary motion into reciprocal motion; to provide such a device which is simple in construction and,l therefore, inexpensive to produce and market; and to provide such a device which comprises a convenient integral stand for maintaining the `brush out of contact with the surroundings.
Other objects and advantages of this `invention will become apparent from the following description taken in connection with the accompanying drawings wherein are set forth lby way of illustration and example certain embodiments of this invention.
FG. 1 is a side elevational View partly in section, showing the motionftranslating linkage of this invention.
FlG. 2 is a fragmentary sectional view rotated 90 degrees from FIG. l showing the motion-translating linkage from a different vantage point.
FIG. 3 is a sectional view taken on the lines 3 3, of
FIG. 2, showing the pin mounting of the projecting rod.
FIG. 4 is a sectional view taken on the lines 4-4, of FIG. l, showing the stationary disc and guide slot therein. FIG. 5 is a sectional view taken on the lines 5 5, of FIG. l, showing the rotating disc with the oifset aperture therein.
FIG. 6 is a detailed sectional view of the joint between the orbiting flink and the projecting rod.
Referring more in detail to'the drawings:
The reference numeral 1 generally indicates an elongated housing containing the operating mechanism of this invention. conveniently held in the hand and carries at the rearward end thereof a pedestal 2 which supports the hou-sing 1 in a vertical position when the device is not in use.
The housing 1 contains an electric motor 3 preferably of the type operable with the usual 60-cycle alternating current found in most households. The motor 3 receives current through electric transmission wires 4.
rlhe motor 3 contains a shaft 5 extending longitudinally of thehousing 1 and adapted to be rotated at approximately 360 r.p.m. by said motor, although such speed is not critica-l. Adisc 6 is secured at the center 7 thereof to the shaft 5 for rotation therewith in a plane transverse to the housing 1. The rotating disc 6 contains an aperture therethrough which is offset from the center thereof. The aperture 8 extends substantially longitudinally of the housing 1, but is formed by sloping bearing edges 9 for a purpose hereinafter described.
A rod lil having an outer end 11 and an inner end 12. projects outwardly of the housing 1 and also extends inwardly thereinto substantially .longitudinally of the housing 1. The outer end 11 has a collar 13 vfixed thereto which extends yforwardly of the outer end 11 and terminates in an internally threaded cylindrical portion 14. The cylindrical portion 14 is adapted to receive a toothbrush 15 supported upon a shaft 16 carrying a threaded end 17. 1t is apparent that various toothbrushes similar The housing 1 is formed so as to ber 3,029,65l Patented Apr. 17, 1962 to the toothbrush 15 may be interchanged therewith to provide sanitary convenience for several persons in a household who wish to use separate toothbrushes with a single electrically operated toothbrush holder.
A pin 18 is mounted transversely to the housing 1 on the forward end 19 thereof by means of a plate Ztl retained thereon with screws 21. The plate Z0 contains a slot 22 therethrough for receiving the rod 10, and a bore 22 intersecting the slot 22. The pin 1S is maintained in the bore 22 and extends through a transverse receiving hole 22 in the rod 10 to pivotally secure the rod 10 with respect to the housing 1 and at a location spaced forwardly from the rotating disc 6. A stationary member or disc 23 is secured transversely in the housing l. and between the pin 18 and the rotating disc 6. The stationary disc 23 has a slot 2.4 therethrough extending in a direction transversely of the pin 18, and adapted to receive and guide the rod 1) in a lateral reciprocal path about the pin 18 (as indicated by the broken lines in FIG. l) but preventing substantial movement at right -angles to said path. The inner end 12 of the rod 10 extends through the slot 24 and terminatesV in a joining means in the form of a pair of integral spaced ears 25 and '26 each having an inner surface 27 and 28 which are mutually parallel and. positioned at right angles to the extending direction of the slot 24.
A link 29 has a forward end 30 exhibiting spaced opposed parallel outer surfaces 31 and 32 positioned respectively in contacting or closely spaced relation with respect to the inner surfaces 27 and 28 of the ears 25 and 26. A pin 33 extends through the ears 25 and 26 and the forward end 30 of the link 29 transversely to the inner surfaces 27 and 2S forming a joint 34 which is pivotable only in a plane parallel to the inner surfaces 27 and 28.
The rearward end 35 of the link 29 extends into and through the aperture 8 which acts as a retainer therefor. The edges 9 of the aperture 8 surrounds the rearward end 35 and provides a bearing surface to support the rearward end 35 during rotation of the disc 6, but permits relative movement therebetween.
The rotating disc 6 imparts an orbital path to the rearward-end 35 of the link Z9. The inner end 12 of the rod `10, however, is permitted movement only in a lateral direction as guided by the slot 24 about the pin 18. It can, therefore, be seen that the vertical component of motion imparted to the rearward end 35 (as seen in FIG. 2) cannot be imparted to the rod 10, but is passively permitted by the bending or pivoting of the joint 34. The horizontal component of the orbital path, however, cannot produce a ybending or pivoting of the joint 34, but Y rather, is transmitted to the inner end 12 of the rod 10, producing a lateral reciprocatory motion about the pin 18 which produces a corresponding reciprocating or vibratory path of the toothbrush 15 in an upwardly and ydownwardly direction which facilitates cleaning of the teeth.
A push button switch 36 may be mounted on the housing 1 to provide a convenient control for actuating the motor 3 to initiate the reciprocatory motion. of the toothbrush.
