Abstract

The present invention refers to a strip-holder which is used in interdental therapy. The main object of the invention is to produce a strip-holder in which the abrasive steel-strip or the steel-sawblade, which is used for the reduction of the tooth width or for the abrading, cleaning and the prophylactic treatment of tooth and filling surfaces in the interdental space, can be easily and quickly inserted into the bow frame of the strip-holder and then tensed. The inventive strip-holder comprises a handle, a flat steel-bow or steel-frame and a gripping device, made of drawn-rod material, for the fixing and tensing of the steel-strip, which is inserted over the outer opening of the steel-bow into grip-slots. These slots are at the two opposite ends of the steel-bow and are cut at these ends into the rod material in such a way as to be slightly wider than the thickness of the steel-strips. The bow-half adjoining the handle of the strip-holder is part of the quick-tensing and gripping-device for the tape-like steel-strip or steel-sawblade.

Dependent claims

A strip-holder for interdental therapy comprising a handle, a steel-bow, a tape-like steel-strip, and a quick-tensing and gripping-device providing grip-openings at opposite ends of said steel-bow for fixing and tensing the tape-like steel-strip over an outwardly facing opening of the steel-bow, wherein:

said steel-bow is substantially flat, approximately U-shaped, and made of drawn-rod material;
said grip-openings are cut in said steel-bow ends so as to provide grip-slots having only a slightly greater width than the thickness of the tape-like steel- strip;
said handle is attached to a portion of said steel-bow and extends outside the bow itself, this bow portion adjoining the handle being part of the quick-tensing and gripping-device for the tape-like steel strip and comprising an internal bow-end having a turning and locking-peg which is pivotally attached to a frame-piece of the U-shaped steel-bow and is perpendicular to said frame-piece;
a prolongation-piece is attached to said frame-piece of the U-shaped steel-bow and is extended so as to form the handle of the strip-holder;
said handle is made of the material of the steel-bow and, in the shape of a loop, is brought to the beginning of the frame-piece of the U-shaped steel-bow, where it forms a segment for the reinforcement of said prolongation-piece attached to said frame-piece of the U-shaped steel-bow;
and,
said turning and locking-peg is placed through bore-holes made in two parallel-running rod-pieces forming said reinforcement-segment.
