2 claims. (i. 1s,167)
This invention relates to tooth brushes and more particularly to an attachment adapted to be removably mounted on a toothbrush of conventional construction.
The primary object of the invention is to provide an attachment of the character indicatedabovehaving a U-shaped cross section and being equipped with a plurality of rows of tufts of bristles secured on the mner sides of the flanges of the attachment extending toward each other and located below the level of the bristles of the tooth brush proper when the attachment is mounted on a tooth brush.
Another object of the invention is to provide an attachment of the character indicated above made of one piece of a resilient material and equipped with projections or the like adapted to enter between and engage the bristles of the tooth brush proper to prevent accidental displacel ment of the attachment in relation to the bristles of the tooth brush.
A further object of the invention is to provide an attachment of the character indicated above comprising a clamping member equipped at its front end portion with a stop for engaging the front end of the head of the tooth brush.
An additional object of the invention is to provide an attachment of the character indicated above the bristles of which are arranged on the inner sides of the outer end portions of the flanges of the U-shaped attachment so that said bristles are adapted to engage the inner and outer surfaces of the teeth being cleaned.
A still further object of the invention is to provide an attachment of the character indicated above the bristle t supporting means of which are easily and readily removable from the tooth brush for the purpose of cleaning the bristles.
With the foregoing objects in view together with such other objects and advantages as may subsequently ap- .f
pear, the invention resides in the parts and in the combination, construction and arrangement of the parts hereinafter described and claimed, and illustrated by way of example in the accompanying drawings in which:
Figure l is a bottom view in elevation of a tooth brush attachment in accordance with the invention mounted on a partly shown tooth brush of conventional construction.
Figure 2 is a side view in elevation.
Figure 3 is an end view in elevation.
Figure 4 is a view in section taken on line 4-4 in Figure 3.
Figure 5 is an end view in elevation of a modified form of a tooth brush attachment in accordance with the invention mounted on a tooth brush of conventional construction.
Figure 6 is a view in perspective of the modified form of the tooth brush attachment, and
Figure 7 is a view in section taken on line 7--7 in Figure 5.
The tooth brush attachment as embodied herein comprises a clamping member 10 having a body 11 adapted to extend across the top surface of the head 12 of a tooth brush B of conventional construction. The front end portion 13 of the body 11 is curved downwardly and tapers outwardly so that this front end portion 13 is adapted to engage the front end of the tooth brush head 12 to prevent the attachment from sliding too far back on the tooth brush.
The longitudinal edge portions 14 and 15 respectively of the lrear end portion of the body 11 are curved downwardly so that they embrace the longitudinal edges of United States Patent O 2,701,380 Patented Feb. 8, 1955 ice .the tooth brush head 1,2- The damping .member 10 is made of a resilient material preferably a plastic such as Lucite or the like so that said member is adapted to be mounted on tooth brush heads of different sizes. The .two curved longitudinal edge Vportions ,14 and 15 are Provided with a plurality 0f projections 16 and `17 respectively extending toward each other and adapted to enter between and engage the bristles 18 of the tooth brush B and which prevent accidental displacement kof the clamping member 10. i
On the longitudinal center line kof the body 1 1 of the member 10 a tapped hole 19 yis provided approximately one-half of the length of said body 11 from the rear end thereof.
A bristle carrier 20. has a U-shaped form and its web 21 rests Ori the rear end portion of the clamping member 1,()v and its flanges 22 and 23 respectively extend downwardly beyondthe bristles 18 of the tooth brush B when the bristle carrier 2.0 is arranged 011 the clamping member 10 and said member is disposed in working position on the brush B.
The bristle carrier is made of one piece of asuitable resilient material preferably a plastic s ueh as Lucite or the'like. The upper end portions 26 and 27 of the flanges 22 and 23 respectively connect said flanges with the web r2.1 and are reduced in thickness and .in Width in comparison with the lower end portions 2,4 and .2,5 of the flanges 22 and 23, and a plurality of bristles 28 are secured to the inner sides of said lower flange portions so that they extend toward each other.
A hole 29 is provided in the web 21 of the bristle car rier 20 so that it will be coaxial with the tapped hole 19 in the clamping member 10 when the bristle carrier 20 is located in working position on the clamping member. A screw 30 having a knurled head 31 or the like extends through the hole 29 and engages the tapped hole 19, whereby the bristle carrier 20 is secured to the clamping member 1i). To prevent a pivotal movement of the bristle carrier 20 about the screw 30 a transverse centrally located groove 32 is provided in the body 11 of the clamping member 10 and a longitudinal rib 33 is formed on the inner side of the web 21 of the bristle carrier 20 to engage the groove 32.
In the Figures 5, 6 and 7 a modified form of the tooth brush attachment in accordance with the invention is illustrated. The attachment as embodied in said figures is made of a suitable, resilient material, preferably a plastic such as Lucite or the like and has a U-shaped body 34 comprising a thin web 35 curved from side to side so that its under side is concave. 36 and 37 of the body 34 extend downwardly from the web 35' and are thicker than said web. The upper portions of the flanges 36 and 37 are reduced in thickness and in width as shown at 38 and 39. On the inside surfaces of the connections between the flanges 36 and 37 and the web 35 ribs 40 and 41 are formed so that they extend toward each other and are provided with inwardly extending projections.
finger 42 is formed on the web 35 and extends forwardly therefrom. The front end portion of said finger 42 is curved downwardly as at 43. A plurality of bristles 44 are arranged on the inside surfaces of the thicker potions of the flanges 36 and 37 and extend toward each ot er.
The attachment as embodied in Figures 5, 6 and 7 is adapted to be mounted on a tooth brush B by pushing it onto said brush from the front until the curved portion 43 of the finger 42 engages the front end of the tooth brush. This action is facilitated by pressing downwardly on the web 35 of the body 34, whereby the flanges 36 and 37 and the ribs 40 and 41 are spread from each other. When the pressure on said web is terminated the flanges and the ribs return into their normal position so that the projections on the ribs will engage the bristles 18 of the brush B.
When an attachment in accordance with the invention is mounted on a tooth brush and said brush is being used, the tooth brush bristles are cleaning the top surfaces of the teeth while the bristles of the attachment engage the inside and the outside surfaces of the teeth. The resiliency of the material of which the attachment is made The two flanges is increased by the shape of the bristle carrying anges and will insure the cleansing of the incisors as Well as the cleansing of the broader molars.
The entire attachment or the bristle carrying portion thereof can be removed easily and readily from the brush for the purpose of purifying the bristles of the attachment.
