Abstract
The improved tennis racket string straightener is a one-piece unitary pocket comb, preferably of molded plastic, with an elongated body and spaced integral teeth depending therefrom along the length thereof. The body has curved ends to prevent pocket snagging and includes a vertical lower plate from which the teeth depend, and a top horizontal flange acting as a hand grip. The plate is integral with the flange and connected thereto along the longitudinal center-line thereof. The teeth in one embodiment are all the same size and spacing. In another embodiment the teeth are of generally similar shape and size but the distance between adjacent teeth gradually increases the farther the teeth are away from the mid-point along the length of the comb. The teeth are generally triangular in front, rear and side elevation, thus generally wedge-shaped with apices pointing down, and the spaces defined thereby are generally triangular with their apices up. All apices are slightly rounded to prevent string damage. The sides of the teeth are recessed to provide raised rims. The rims, teeth, flange and plate are not more than about 1/4 inch thick for maximum dimensional stability during molding.
