Abstract

An elongated handle has a head at one end. The head has four flat surfaces extending in the longitudinal direction which are arranged into two pairs of opposite parallel surfaces, one pair extending at right angles to the other pair. Each two adjacent surfaces are separated by a rounded edge extending in the longitudinal direction. Bristles disposed in rows extending in said direction extend outward from each of three adjacent surfaces at right angles thereto. Additional non-intersecting rows of bristles also extending in this direction extend outward in a non-intersecting manner from the edges disposed between each of the outer adjacent surfaces and the inner adjacent surface.

1 DEVICE FOR BRUSI-IING DENTURES SUMMARY OF THE INVENTION My invention is directed toward a new type of brush which can be used for cleaning dentures and is so constructed that, when manually operated, a variety of different surfaces of a denture can be cleaned simultaneously.

To this end, I employ an elongated handle having a head at one end. The head has four exposed flat surfaces which extend in the direction of elongation and which are separated by rounded edges extending in this direction. The surfaces are arranged into two pairs which extend at right angles to each other, the two surfaces in each pair being opposite and parallel.

Bristles arranged in rows extending in this direction are secured to each of three adjacent surfaces and extend outward at right angles thereto.

Additional parallel rows of bristles can extend outward in a non intersecting manner from the two edges disposed between the central one of the three adjacent surfaces and each of the two outer surfaces included in the three adjacent surfaces.

In operation, the handle is held in one hand, the denture is held in the other hand, and the head can be used together with conventional paste powder or the like to clean the denture. The number and position of the various rows of bristles enables a variety of denture surfaces to be cleaned simultaneously.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:

FIG. 1 shows one side view of my device;

FIG. 2 is a rear view thereof;

FIG. 3 shows an opposite side view thereof; and

FIG. 4 shows a cross sectional view taken along line 4-4 in FIG. 2.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to FIGS. 1-4, an elongated handle has an elongated head 12 which in cross section defines a rectangle 14 with rounded edges 16. The head has a first pair of opposite

parallel surfaces

18 and 20 which extend in the direction of elongation and a second pair of

parallel surfaces

22 and 24 which extend in the direction of elongation and are perpendicular to pairs 18 and 20. Each two adjacent surfaces are separated by a rounded edge 16 which extends in the direction of elongation.

First and second sets of parallel horizontal bores 26 are disposed in the head and extend between

surfaces

18 and 20. Bristles 28 are disposed in each bore whereby two rows of bristles, disposed along the direction of elongation, extend outward at right angles to these surfaces. Bristles 30 are set into recesses in surface 24 and define two parallel rows, extending along the direction of elongation, extend outward at right angles to surface 24.

Bristles 32 are set into recesses in edges 16 disposed between surface 24 and surface 20 and between surface 24 and surface 18. Each edge carries one row of bristles which extends in the direction of elongation and also extends outward in a non intersecting manner between

bristles

30 and 28 and typically at an angle of 45 with respect to

surfaces

24 and 18 or

surfaces

24 and 20.

The invention can then be used as described.

While I have described my invention with particular reference to the drawings, such is not to be considered as limiting its actual scope.

Having thus described the invention, what is asserted as new is:

I. A device adapted to be manually operated to clean dentures by brushing, said device comprising:

an elongated handle with a head at one end, said head in cross section defining a rectangle with rounded corners and thus having four flat surfaces extending in the direction of elongation, oppositely disposed surfaces being parallel whereby two pairs of paralleled surfaces extend at right angles to each other, each two adjacent surfaces being interconnected by a rounded edge extending in the direction of elongation;

first bristle means secured to a first head surface and including first and second parallel rows of bristles extending in the direction of elongation and extending outward at right angles to the first head surface;

second bristle means secured to a second head surface parallel to the first head surface and oppositely disposed thereto, said second means including first and second parallel rows of bristles extending in the direction of elongation and extending outward at right angles to the second surface whereby the first and second means extend outward in opposite directions;

third bristle means secured to a third head surface which extends between the first and second surfaces at right angles, said third means including first and second parallel rows of bristles extending in the direction of elongation and extending outward at right angles to the third surface, said third means extending at right angles to the first and second means; and

fourth and fifth bristle means, each of the fourth and fifth bristle means including a single row of bristles extending in the direction of elongation and being secured to a corresponding one of the edges between the first, second and third surfaces, each of the fourth and fifth means extending outward at right angles to the corresponding edge and not intersecting with any other means.

Claims

1. A device adapted to be manually operated to clean dentures by brushing, said device comprising: an elongated handle with a head at one end, said head in cross section defining a rectangle with rounded corners and thus having four flat surfaces extending in the direction of elongation, oppositely disposed surfaces being parallel whereby two pairs of paralleled surfaces extend at right angles to each other, each two adjacent surfaces being interconnected by a rounded edge extending in the direction of elongation; first bristle means secured to a first head surface and including first and second parallel rows of bristles extending in the direction of elongation and extending outward at right angles to the first head surface; second bristle means secured to a second head surface parallel to the first head surface and oppositely disposed thereto, said second means including first and second parallel rows of bristles extending in the direction of elongation and extending outward at right angles to the second surface whereby the first and second means extend outward in opposite directions; third bristle means secured to a third head surface which extends between the first and second surfaces at right angles, said third means including first and second parallel rows of bristles extending in the direction of elongation and extending outward at right angles to the third surface, said third means extending at right angles to the first and second means; and fourth and fifth bristle means, each of the fourth and fifth bristle means including a single row of bristles extending in the direction of elongation and being secured to a corresponding one of the edges between the first, second and third surfaces, each of the fourth and fifth means extending outward at right angles to the corresponding edge and not intersecting with any other means.
