TOOTH-BRUSHES AND THE LIKE Filed Oct. 14, 1955 2,935,755 v TOOTH-BRUSHES AND THE LIKE Alberto Ramon Leira and Vitalicia Hortensia Sanin Cabo,

Buenos Aires, Argentina Application October 14, 1955, Serial No. 540,585 1 Claims. c1. 15-167) The invention relates to improvements in tooth-brushes and the like such as massage brushes, and more particularly it refers to an improved arrangement of the bristles or the like so that a better cleaning or massage may be carried out.

The tooth-brushes so far well known are all of the fixed bristles type, that is to say that the bristles are stationary mounted in the bristles supporting portion 'or housing of the handle, and different designs have been proposed as to the operating surface 'of the bristles so as to achieve better cleaning results for the teeth.

With these known types of tooth-brushes it is necessary to apply a substantial pressure, in order to be able to reach as far as possible all the different interstices, which method is erroneous and even injurious if the user has a delicate gum. Accordingly it has been considered that the ideal toothbrush would be one which is able to efliciently clean the teeth with a minimum of pressure, by adapting the bristle tips to the shape of the surface to be cleaned.

Thus, the present invention consists of a tooth-brush comprising a handle including a bristle supporting portion, a plurality of bristle assemblies slidably mounted substantially along their respective longitudinal axes in said bristle supporting portion, flexible, inextensible means in said bristle supporting portion, said bristle assemblies resting on said means.

. Although reference has so far been made only to bristles it is obvious that a brush for massages could be provided in accordance with the present invention, wherein the bristles are substituted by rubber 'pins or the like.

From the foregoing it will be apparent that it is an object of the present invention to provide a tooth-brush or the like, which always will be able to adapt its brushing surface to the surface to be brushed, and to maintain this feature even if the brush is moved along an irregular surface.

Another object is to provide a-tooth-brushof simple structure and low manufacturing cost.

These and further objects and advantages of the present invention will become more apparent during the coarse of the following description, wherein by way of example several embodiments have been described and shown in the accompanying drawings.

in the drawings:

Figure 1 is a perspective view, partially in section of part of a tooth-brush according to a first embodiment of the present invention.

Figure 2 is a longitudinal section along line 11-11 of Figure 1.

Figure 3 is a cross section along line III]1H of Figure 1.

Figure 4 is a partial perspective view of a second embodiment, similar to Figure l.

Figures 5 and 6 are similar longitudinal and cross sections, respectively, as Figures 2 and 3, of the embodiment shown in Figure 4.

United States Patent 0 ice Fig. 7 is a perspective view of the partition arrangement of the embodiment of Figs. 4 to 6;

Figure 8 is a side elevation of a modified structure showing a rubber pin.

As may be seen in Figure 1, the tooth brush consists of a handle 1 having abristle supporting portion or housing 2 and a cover 3, said cover 3 having a plurality of spaced apart holes 4 defining in this embodiment three banks of holes. Each bank of holes 4 is destined to receive a corresponding number of bristle assemblies 5 each mounted in a U shaped bristle holder 6.

The housing 2 and more particularly, the lower base 2' thereof is integral with a plurality of upstanding transversal partitions 7 located between pair of rows ofv holes 4 and each partition 7 has in this embodiment three recesses 8 facing one of the banks of holes 4, so that the total of the partitions 7 define three longitudinal channels, in each of which a flexible inextensible band 9 is housed. The length of each flexible inextensible band 9 is preferably considerablylonger than the length of the housing 2, more particularlythe distancebetwen the front wall 10 and the rearwall 11 into which the ends of the bands 9 are fastened, so that a band of irregular shape, as best seen in Figure 2, is obtained. I

Each U shaped bristle holder 6 straddles on one of the bands 9 and the bristles pass through the correspondin hole 4.

It will now be understood that when one or more bristle 5 of one band are depressed others will be raised sliding along their respective longitudinal axes a and the flexibility of each bank of bristles is sufficient so as to adapt the tooth brush to the plurality of convexities defined by the outer side of a row of teeth or to the plurality of concavities defined by the inner side of a row of teeth (not shown).

Conveniently, housing 2 is provided with a plurality of additional holes such as holes 12, to enable to discharge the liquid which may have entered the housing 2.

In the embodiment shown in Figures 4 ,to 7, the same concept is used, although the bands 9 are replaced by air cushions 20 or hollow flexible containers, inextensible along their respective longitudinal axes and filledwith any suitable means such as air, gas or liquid. The tooth brush as such comprises in this embodiment a lid 21 forming the lower base of the housing 22 and which lid 21 (see Figures 3 and 7) may be provided with small ribs 23 which are arranged opposite partial longitudinal partitions 25 integral with the upper base portion 26 of the handle 27, thereby defining in this embodiment three channels into which the corresponding elongated resilient cushions 20 are located, which are inextensible along their longitudinal axes since the ends thereof engage the ends or the front and rear walls of the housing 22, but they are not inextensible and resilient in the same direction. The bristle holders 28 are small blocks each of which may be provided with a tubular projection 29, the height of which is sufficient to assure that they act as a bushing in the holes 30 of the base 26, so that the bristles 31 are not able to wedge the hole 30.

Alternatively, the upper base 26 may be of suflicient width, that the tubular projection becomes unnecessary.

The lid 21 may be withdrawn for cleaning purposes of the brush and for replacement of spare units of bristle assemblies.

As to the cleaning purposes only, the lid is obviously not necessary, since by means of the vent holes 12 it is possible to submerge the housing into a disinfectant liquid, which enters the housing and as soon as said housing is withdrawn from the disinfectant liquid, the latter is evacuated through said vent holes.

It is not considered necessary to enter further details as to the second embodiment shown in Figures 4 to 7 in view of the foregoing description made in connection with the first embodiment corresponding to Figures 1 to 3. In case the brush is to be used for massages, each of the bristles 5 or 3-1 may be replaced by a massage 'pin 32 (see Figure 8), as will be apparent to those skilled in the art. These massage pins 32 are usually made of rubber or the like.
