A racket structure to be used in a tennis and the like racket and a method for producing it, where the handle section and the head frame section are made of a one-piece composite member including an inner lightweight soft plastic core member having a central prestressed multifilament cord member and a glass fibers reinforced hard plastic, outer surrounding layer, anchored on said core member within the head frame section, said surrounding layer being covered on opposite faces with respective resilient flow cover members which also sheath part of the height of said head frame section on the inside face, facing the netting, defining the striking surface stretched in the oval space defined by the head frame section of the racket.
A racket structure comprising a one-piece composite member having two contiguous parallel straight end portions continuing into an intermediate open oval shaped, arcuate portion, a bridge portion extending between and connected to said end portions adjacent the beginning of said arcuate portion and closing said open oval shaped, arcuate portion, said bridge and oval portions defining a head frame section for stringing with a taut string, said head frame section to form a striking surface, said parallel straight end portions defining a handle section with a grip, said one-piece composite member having an inner light-weight soft plastic core member defining a longitudinal center line and having an inner face, an outer face and further including a central prestressed longitudinal cord member, said open oval shaped arcuate portion of said core member having between said center line and said outer face, crosswise to said center line arranged spaced apart anchoring recesses each continuing by a bore from said center line towards said inner face, each of said bores being oriented towards the space circumscribed by said frame section, a glass fiber, reinforced outer hard plastic layer, sheathing said core and entering said recesses by way of anchoring portions, each of said anchoring portions including a perforation coaxial with the pertinent bore, a pair of resilient, flat cover members mounted an opposite sides on said composite member, each cover member having a head portion and a handle portion, each head portion being of oval shape substantially equal to the shape of said head frame section, each handle portion being of substantially the same shape as said handle section, an endless oval shaped inner rim integral with said head portion, the height of said rim being less than half the height of the inner face of said head frame section, and each rim abutting on said inner face and leaving between them a central free portion into which end said bores for said string.
