Abstract

Ball game racket, especially tennis racket or squash racket has a frame made of plastics, which in the plane of stringing provided on the head is designed in two parts and whose halves exhibit a trough-shaped cross section profile--open toward central plane (M)--with a concave wall, whose two longitudinal sides, bordering the open side of the cross section profile, are adjacent to central plane (M). The halves are connected to one another by connecting pins, formed on the respective wall, as well as sleeve-like sections receiving them. The connecting pins and sleeve-like sections each merge directly into the wall in the area of longitudinal sides or alternately to this the frame halves, at least on some connecting pins provided on the head and/or sleeve-like sections, exhibit a distance from one another, and the strings forming the stringing are run around these connecting pins or sleeve-like sections.

Dependent claims

A racket including:

a hollow frame comprising a handle and a head for supporting an array of strings in a central plane, the frame being formed from two frame portions disposed on opposite sides of said central plane, each said frame portion is integrally formed by plastic molding with a handle portion and a head portion, said head portion having an inwardly concave wall exhibiting two longitudinal wall edges adjacent to said central plane and facing said central plane, wherein said frame portions are identical with respect to the size and shape of the handle portions and head portions;
each said head portion having interfitting pin and sleeve connectors extending from its concave wall for engagement with complementary connectors on the other of said head portions, said pin and sleeve connectors each merging into the concave wall of each of said two longitudinal wall edges, said concave walls being spaced apart in the vicinity of at least some of said connectors to permit the strings to be strung around the connectors such that the strings are supported by the connectors, and said pins are hollow and have a diameter equal to at least half of the width of said head as measured in a direction parallel to said central plane.
