Abstract
A racquet extending along a longitudinal axis includes a frame formed of a thermoplastic material. The frame includes two halves having two spaced apart hoop regions, two handle regions and two mating surfaces. One of the halves includes a set of projections extending from one of the mating surfaces. At least one of the halves defines a set of bores. The projections are configured to engage the bores. At least two of the projections are stepped projections having a proximal section and a distal section. The transverse cross-sectional area of the proximal section is greater than the transverse cross-sectional area of the distal section. Two of the bores are configured to receive the corresponding distal sections, but not the proximal sections, of the two stepped projections, such that the projected height of the proximal section of the two stepped projections substantially defines the spacing between the hoop portions.
