Definitions

  • This invention relates to an improved sports racket, in particular an improved tennis racket.
  • US-A-4 437 662 and EP-A-93 210 also relating to a sports racket, disclosed a string network, wherein a majority of longitudinal strings, inclined at a moderate angle with respect to the axis of the frame, converge from the head towards the handle and are anchored at a string anchoring device in the shank region behind the throat. This long converging string system improves power and control of the racket.
  • the present invention uses a similar stringing concept, but the frame of the racket takes the form of the earlier classical wood racket form in which the throat is not the open yoke type, and the shank is a long beam which extends from the throat to the handle.
  • a sports racket comprising:
  • a tennis racket is used to illustrate the innovative concept, but it is understood that the concept applies to other applicable sports rackets.
  • Fig. 1 is a plane view of a racket 1 according to a preferred embodiment of the invention in section through the stringing plane of the frame, comprising a racket body 2 having a longitudinal axis 3.
  • the racket body 2 is composed of a handle 4 and a frame 5 composed of structural load-carrying boundary members, including, from top down, a head part 6, a middle part 7, a curved throat element 8 and a straight shank element 9 connecting the throat element to the handle.
  • the body of the racket also includes a string system defining a stringing plane 10, shown in Fig. 2, which coincides with the mid-plane of the racket body, composed of two string segment systems.
  • Each string segment possesses two ends, attached to the frame.
  • the lateral string segments 11 run substantially perpendicular to the longitudinal axis 3, and intersect with the longitudinal string segments 12.
  • Fig. 2 shows a section along the line A-A of the throat element 8 of Fig. 1, wherein a majority of the longitudinal string segments pass through the opening 21, towards the shank element 9.
  • Fig. 3 is a cross section along the line B-B of the shank element 9 of Fig. 1.
  • the cross section shows an I-beam as an example, wherein a plurality of the longitudinal string segments 12, which pass through the opening 21 of the throat element, is converging to the anchoring region, a region 30 between the throat element and the handle, which is generally referred to here as the region of the shank element.
  • the upper flange 32 of the cross section may join the upper wall 22 of the throat of Fig. 2, and the lower flange 33 may join the lower wall 23.
  • FIG. 1 A preferred arrangement of anchoring the longitudinal string segments in the shank element region 30 is shown in Fig. 1 by installing a string seat element 13, which is shown as a bar element in the stringing plane, rigidly attached to the shank element thereof, extending outwardly as an arm in a symmetrical manner on both sides of the central column 31. There may be more than one of such seat in the shank element.
  • a characteristics of the present invention is that at least for two side string segments, one on each side of the longitudinal axis, such as 14 and 15 in Fig. 1, after exiting from the opening 21, which are anchored in the region between the throat element 8 and the handle 4, there is no structural, load-carrying member of the frame standing between said side string segments and the outboard space beyond, such as the space 16 and 17 respectively in Fig. 1.
  • the boundary encircled by the structural members of the frame is not continuous.
  • the majority of the longitudinal string segments generally converge from the head part towards the shank element, ie they are typically spaced further apart from each other at the head part than at the shank element.
  • the structural discontinuity in the boundary of the frame may be disguised by a lightweight, non-structural connecting member.
  • this mending member is a structural load-carrying member or not can be seen by a simple test: If the frame can stand the rigour of ball playing after the shank element is cut between the throat element and the seat element, then the connecting member is a structural, load-carrying member, which has made the frame continuous; a frame having such a disguising member and shank element is not claimed by the present application. Otherwise, the disguising member is purely decorative; the racket with a seemingly continuous boundary is within the claims of the present invention.
