Application April 28, 1947, Serial No 74 4:, 1 21 'lClaim. (crane-4;)
This invention relates to new and useful improvements in toothbrushes. In particular, it is concerned with toothbrushes of the adjustable type, having relatively movable brush and handle portions, with the backs of each lying in substantially the same plane.
In my novel toothbrush, the brush or head portion and the handle portion being substantially and smoothly in the same plane provides a compact and streamlined structure fully equivalent to that of any non-adjustable brush now known to me. My brush has the additional advantage of being fully and easily adjustable, over a wide angle and within the common plane of head and handle thereof, so that proper care of all surfaces'of the teeth may be effected. Furthermore, the adjustment mechanism is concealed, i. e., is self-contained within the interior of the toothbrush. The application of required torque between head and handle, as by mere finger pressure, will change the relative angle therebetween; yet the adjustment is suficiently stable, when once made, to prevent any changes by forces exerted during normal use of the toothbrush for its intended purpose.
The invention will be more readily understood by referenceto the accompanying drawing, in which:
Figure l is a fragmentary perspective view of one form of my improved toothbrush,
Figure 2 is a vertical section of a part of the brush on the line 8-8, Figure 1, and
Figure 2A is a bottom plan View of a portion of the brush-head.
Similar numerals refer throughout the several views.
In Figure 1, handle Ill, terminating in semicircular portion 1 l, and brush-head l2, terminating in cooperating semi-circular portion [3, are in the same plane and in adjustable relationship therein about the central axis of semicircular portions II and I3. The brush-head carries clumps of bristles l4, cemented or otherwise anchored in suitably spaced holes l5. Handle l and head l2 are permanently but movably held together by hollow rivet l6 and solid rivet l1.
As shown in Figure 2, the combination of hollow rivet l8, solid rivet I! having its stem internally located therein, and coiled compression spring 19 placed around the shank and beneath the head of hollow rivet l8, holds semi-circular portion l3 of brush-head l2 firmly pressed against cooperating semi-circular portion ll of handle ill. The internal or cooperating faces of circular portions II and I3 contain to similar parts 4 respectively radial depressions l9" and-cooperatmg radial protrusions 20, equally spaced, e. g., as shown inFigure 2A, andpreferably of rounded or semi-circular cross-section. The shank of solid rivet l'l fits tightly within'hollow rivet [8,- and its exposed tip may additionally be peened'.
over or otherwise secured so'as to hold the assembly firmly together.
With the arrangement shown in Figures 1 and 2, it will be apparent that the brush-head 12 may be moved sidewise in either direction with respect to the handle Ill, about the axis of the rivet l1, and furthermore that it will be quite rigidly held in any one of the several possible positions defined by cooperating protrusions 20 and depressions l9, by means of compression spring l9.
In place of rivets, other means for holding handle and brush-head portions in assembled relationship may be employed. For example, screws or bolts may be used, in which event the head may readily be removed and replaced.
Other means of locking the head in the desired angular position may also be employed.
It will be apparent that, although the brushhead I2 is in the same plane as the forward portion of the handle, particularly the semicircular portion thereof, and in effect forms an extension thereof, the rearward portion of the handle may if desired be in some other plane at an angle with the plane of the forward portion.
The adjustable feature of my novel toothbrush provides distinct advantages when employed with brush-heads having the conventional uniform arrangement of bristles, and in which the clumps of bristles may be restricted to any desired area of the face of the brush-head, or may be spaced over the entire face including the semi-circular portion. A further distinct improvement is obtained by the combination including an arrangement of bristles as indicated in Figures 1 and 2, wherein the bristles in effect form a wedge with the peak of the wedge above the longitudinal axis of the brush-head and inclined upwardly from the juncture of head and handle. With this arrangement of bristles, and with the brush-head at a sharp angle with the handle, proper care of the teeth is greatly facilitated, since the peak of the wedge may then readily be placed directly in line with the vertical spaces between adjacent teeth.
What I claim is as follows: v
In an adjustable toothbrush, an adjustable head and handle comprising: a handle having at one end a flat semi-circular axially perforated hinge portion having an interior face and an exterior face; and, as an angularly adjustable extension thereof, a brush-head having, at the end adjacent the handle, a flat semi-circular axially perforated hinge portion having an interior face and an exterior face; one of said interior faces having equally spaced radial depressions and the other having cooperating equally spaced radial protrusions fitting within said depressions; the axial perforations of one of said joint portions terminating at the exterior face in an enlarged recess; a compression coil spring fitting within said enlarged recess; a hollow rivet passing through the axial perforations of said hinge portions and passing through said coil spring, and having a flat head fitting within said enlarged recess and over said spring, holding said spring under compression, and holding the said hinge portions in adjustable cooperating relationship with the two interior faces together; and a solid rivet with its stein fitting, tightly within the axial bore of, said hollow rivet, said solid rivet retaining said hollow rivet in place against the pressure of said compression spring FERDINAND ROBERT HAUPT.
