Patent ID: 8574103

Claim:
A ball striking implement comprising: (a) a head frame which is hollow and made from it fiber-reinforced plastics material by injection molding or by laminating, with prepregs the head frame comprising an impact surface determined by at least one string which is stretched crosswise and forms string portions fastened to the head frame substantially parallel to one another by means of arcuate or bow shaped holding elements; and (b) a stem which is formed integrally on the head frame and comprises a handle, wherein the arcuate or bow shaped holding elements are embedded and fully integrated in the head frame and each arcuate or bow shaped holding element has a central part in the shape of a sector of a circle and two curved legs corresponding to the curvature of the head frame in a region of the upper inner edge and lower inner edge of the head frame, and wherein a plane defined by the arcuate or bow shaped holding elements is substantially perpendicular to the impact surface, whereby the string portions are positioned in a single plane forming the impact surface, such that ends of the string portions perform a lateral movement in the arcuate or bow shaped holding elements upon impact of a ball, which results in a lateral deflection of the entire impact surface.
