Abstract
A toothbrush having an elongated handle, the handle defining a center plane containing the longitudinal axis. A pair of bristle-bearing segments, each segment containing a plurality of bristles mounted therein, is connected to the handle by a pair of short arms. The arms, bristle-bearing segments, and the handle form a fork having two prongs, each prong containing one bristle-bearing segment and one connecting arm. The prongs are located on opposite sides of the first center plane and below a second center plane perpendicular to the first center plane. The bristle-bearing segments have mutually facing inside surfaces sloping toward each other in a gable-manner and intersect above the upper side of the handle at a first angle of less than 55.degree.. The free ends of the bristles bound a gap and define side surfaces sloping in a gable-manner toward each other intersecting above the gap and at a second angle which is less than the first angle.

4938539 - Process for producing a toothbrush and toothbrushes produced by the process

A toothbrush blank having a handle, a pair of head portions provided with a plurality of bristles receiving bores on one side of the head portions, and a narrow hinge-forming V-shaped cavity or groove formed on the same bristle receiving side of the head portions. The V-shaped groove enables the head portions to be bent in a convex arch so that the bristles can be cut and polished in a common plane. Thereafter, the head portions are bent towarad each other into a finished condition where the side surfaces of the V-shaped groove form support abutments which are glued or welded against each other.

7175238 - Process and arrangements for producing a toothbrush, the toothbrush, and also the use of the toothbrush

A method and a device are described for manufacturing of a toothbrush from a starting-material which comprises a handle that runs into a neck part which divides into two equal and diverging arms/head parts, in which the bristle-carrying surface (bottom surfaces) of the head parts is approximately in a plane which runs parallel to the main axis of the toothbrush and head, and in which bristle which extend approximately vertically out from the surface is inserted and is of approximately equal of different lengths. According to the invention the starting-material is arranged in a shaping appliance in which the neck and head part adjacent to the respective associated arms, is supported with its underside on a support body, and the two head parts are bent, in particular by twisting/deformation, to the desired angle position by torsion-twisting of the two arms/heads along the respective axes approximately parallel to the center-line axis of the handle, approximately at the same height as the underside of the neck part, so that the edges of the head parts and the upper sides of the arms in the V-shaped opening form a head part with decreasing height towards the foremost part of the head part. The manufactured toothbrush is particularly suited to animals, in particular domestic animals, pets and especially intended for dogs and cats but can also be used by humans.

4876157 - Process for producing a toothbrush and a toothbrush blank for use in the process

A toothbrush blank having a handle, a pair of head portions provided with a plurality of bristles receiving bores on one side of the head portions, and a narrow hinge-forming V-shaped cavity or groove formed on the same bristle receiving side of the head portions. The V-shaped groove enables the head portions to be bent in a convex arch so that the bristles can be cut and polished in a common plane. Thereafter the head portions are bent toward each other into a finished condition where the side surfaces of the V-shaped groove form support abutments which are glued or welded against each other.

5114214 - Process for producing tooth brushes and blanks for use for same

A process for producing a toothbrush produced thereby have the cavities (11, 12) arranged on the back side of the tooth brush head. The longitudinal axes (14a, 15a) for angling the head portions (13, 14, 15) relative to each other are arranged on or at the bristle-carrying side of the head portion directly opposite the associated cavity (11, 12). A blank for carrying out the process and a toothbrush produced thereby have the cavities (11, 12) arranged on the back side of the toothbrush head. The longitudinal axes (14a, 15a) for angling the head portions (13, 14, 15) relative to each other are arranged on or at the bristle-carrying side of the head portion directly opposite the associated cavity (11, 12).

4763379 - Cleaning device

A hand tool facilitating removal of cobwebs and the like from ceilings, walls, baseboards and furniture without smudging the same and without the necessity of stooping or standing on an elevated support to accomplish the same. The tool is comprised of a circular base with a pair of opposing tracks or recesses provided therein adapted to engage and support a complementary nose piece thereon. The nose piece in turn has a lining or covering of flocking to attract cobwebs, dust and dirt, etc., and a plurality of spaced semi-circular projections along the exterior to prevent the entire surface from contacting and soiling the wall while in use. A socket is provided for receiving a handle to manipulate the same.
