PROTECTIVE GUARD FOR TOOTHBRUSH Filed Nov. 28, 1952 INVENTOR. MYRON B. GREEN u/ma #cm/ ATTORNEYS United States Patent PROTECTIVE GUARD FOR TOOTHBRUSH Myron B. Green, Minneapolis, Minn. Application November 28, 1952, Serial No. 322,924
6 Claims. (Cl. 15-143) The present invention relates to improvements in a protective guard for a toothbrush. In general it relates to a guard structure for use with a toothbrush to prevent fluids on the bristles from flowing to the handle and also acts to prevent the bristles from coming in contact with a surface on which the brush may be laid. In particular it relates to a guard having a dual function of protecting the bristles of a toothbrush from coming into contact with a contaminating surface when the brush is either laid or accidentally dropped on the surface and which further acts to prevent fluids such as suds or saliva from flowing from the bristles onto the hand of a person using the brush.
In the active use of a toothbrush, several factors enter into its use other than the mere scrubbing of teeth. Frequently, fluids on the brush will flow down the handle onto the hand of the user and under certain conditions this may be highly annoying. Furthermore, when a person has completed use of a brush and attempts to lay the same onto a supporting surface such as a wash stand, it is desirable that the bristles be held in spaced relation to the wash stand to prevent contamination of the bristles. Still further, almost everyone has experienced the annoyance of accidentally dropping a toothbrush, and if the same descends to the floor it is highly desirable that the bristles be held in such a manner as to avoid contact and contamination by the floor surface.
My present invention incorporates a guard which may be attached to a toothbrush but is preferably formed integral with the toothbrush handle. A particular feature of the guard is that it has an oil? center relationship with the brush handle so as to always cause rotation of the brush handle in such a manner as to hold the bristles in spaced relation to any surface with which the brush may come into contact. Another feature is that the guard is composed of a pair of such cams interconnected with each other to form a double barrier between the bristles and the handle, which will prevent any fluid from creeping over the double cam surface to the handle.
An object of the invention is to provide in combination with a toothbrush, of aguard in the form of an off center cam which is capable of holding the bristles in spaced relation to any surface on which the brush may be laid and for causing rotation of the brush with respect to a contacting surface to always hold the bristles away from contact with the surface.
Another object is to provide an eccentric shaped off center cam which acts as a guard between the bristles of a toothbrush and its handle and to cause rotation of the brush when the latter comes into contact with a surface so as to hold the bristles away from the surface.
Another object is to provide a guard in the form of two interconnected cams which are mounted in off center relationship to a toothbrush handle to prevent fluids from flowing from the bristles to the handle and also cause rotation of the brush when the latter comes into contact with a surface to hold the bristles away from contaminating contact with said surface.
w ce
Other and further objects may become apparent from the following specification and claims, and in the appended drawings in which:
Fig. 1 is a side elevation of a toothbrush incorporating my invention;
Fig. 2 is an enlarged cross section taken on line 22 of Fig. 1 showing one form of toothbrush guard; and,
Fig. 3 is a view similar to Fig. 2 of a modified form of guard such as is shown in Fig. 1.
Referring now to the drawings, general reference numeral v10 indicates a toothbrush including a handle portion 12 having an aperture 14 at one end to support the brush on a hook, and a curved forward end 16 that supports a plurality of. tufted bristles 18 on one lateral side of the handle 12.
A guard indicated by general reference character 20 is placed on the handle at the center of balance and yet far enough away from the bristles 18 to prevent any possibility of interfering with the proper brushing of the teeth. The guard is preferably formed integral with the handle as it is desirable that it be situated at about the point of balance between the opposite ends of the handle. Guard 20 is composed of cam 22 having a beaded edge 23 and cam 24 having a beaded edge 25. The two cams are spaced from each other and connected by a narrow neck portion 26.
Referring now to Fig. 2, the guard 20 is shown in a slightly enlarged scale. It will be noted that cam 24 is of an eccentric shape and is of a type generally referred to as a heart-shaped cam having -a relatively flat lower surface 28 but with the major portion of the cam 30 extending in the same direction as the bristles 18. It will be further noted that the handle 12does not pass through the center of the cam but rather is in off center relation ship thereto, being on the side closest to the surface 28.
Referring now to Fig. 3 is shown a guard which differs from guard 20 only as to the shape of the cams. Shown in Fig. 3 is a cylindrical cam 32 which-is connected to a similar cam, not shown, by a connecting portion 34. The cam 32 has a beaded edge 33. Like cam 24, cam 32 is secured in an oil? center relationship to handle 12 so as to have its major portion designated by reference character 36 on the same .side of the handle as the bristles 18.
When a toothbrush is inactive use in brushing the teeth, it frequently occurs that fluids, such as water, cleanser or saliva will flow .from the bristles 18 in the direction of the handle portion and will flow onto the hand of the user. Guard 20, whether of the type shown in Fig. 2 or Fig. 3, by being composed of two spaced apart members, will prevent the fluid from flowing to the hands since the beaded edge 33 of cam 22 of Fig. 1 will tend to form a barrier to prevent the fluid from passing across the center connection 26 to the second cam 24, whose beaded edge 25 acts as a further barrier since fluid will not normally pass through the space of the center connection 26 and over the beads 23, 25. Of equal importance is the fact that guard 20, being situatedat the center of balance and having the major portion of each of the cams extending on the same side of the handle .12 as the bristles 18, will act as an eccentric to cause rotation of the handle when laid or droppedona supportingrsurface such as a wash stand or shelf, thereby always turning the brush with the bristles upwardly. The function of the off center guard is of equal importance in the event that the brush is accidentally dropped such as to a contaminated floor surface, since the guard is situated at the balance of the handle the brush will always tend to fall on the guard and by reason of its off center relationship with the handle will cause the handle to'roll over to hold the bristles upwardly and away from contact with the floor. This function is particularly applicable to the guard made up of the heartshaped cams of Fig. 2.
The advantages of my invention reside in the provision of a toothbrush guard which prevents fluids from flowing from the bristles to the hand and also in the provision of an off center relationship with the handle so as to cause the brush to rotate to a position with the bristles held away from a contacting surface when the brush is laid or dropped on said surface.
