DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a handle of the kind defined in the preamble of Claim 1.
The invention is directed to sport implements, preferably implements for ball sports where high demands are placed on the contact, i.e. grip, between hand and implement, more preferably to tennis rackets, badminton rackets, squash rackets, baseball bats and cricket bats, golf clubs and similar implements, although the invention can also be applied advantageously in other fields, such as with tools, for instance, where an ergonomical design of the tool handle can result in significant improvements in efficiency.
Sporting implements have been the subject of highly comprehensive developments and new materials and new designs have made possible sporting results that were earlier considered to be totally unachievable. This applies to practically all fields of sport, for instance pole vaulting, skiing, tennis, golf, etc., and attempts by "old masters" to use their old sporting implements and equipment when making a comeback has resulted in catastrophical failure.
The present invention is described with reference to tennis, although as before mentioned measures that are immediately evident or measures which will be obvious to the skilled person can be applied to practically all racket sports and also other sporting fields and areas.
The game of tennis has become faster and actively more precise, the racket blade has become larger and new materials have been used in the strings, frames and shafts of the tennis rackets. The actual grip around the shaft, however, has not been changed to any great extent and the handle of the tennis racket has in the main the same octagonal shape as in the childhood of tennis.
BACKGROUND ART
Many attempts have been made earlier to improve the handles of tennis rackets and like implements, although the majority of these endeavours have been directed towards producing handles that are custom-built to suit the individual.
U.S. Pat. Nos. 4,696,842, 4,765,856 and 4,785,495 relate to handles for tennis rackets and tools which include ridges and intermediate finger grooves.
U.S. Pat. No. 3,868,110 describes a similar tubular handle which is intended to be fitted to a racket shaft and which has two thumb grooves or recesses which enable the grip on the handle to be changed precisely and simply when switching between forehand and backhand strokes.
According to U.S. Pat. No. 4,147,348, a similar handle is angled at about 32.degree. to the remainder of the shaft so as to provide a pistol grip fitting, and the handle may also be angled at 5.degree. to the blade. The grip is intended to be customer-made from an uncured, soft epoxy resin and is gripped by the individual concerned until the resin has hardened.
DOS 2,746,168 and 3,616,414 describe similar handles and different methods of imparting individuality to the handles by a tennis player gripping around soft, uncured resin with his/her playing hand so as to mould the plastic to the individual grip of the person concerned. The resin is then hardened.
GB-A 2,133,294 relates to a handle which is formed anatomically by two half tubes which are fixed to the shaft.
GB-A 2,169,839 relates to a cricket bat handle provided with finger grooves.
U.S. Pat. No. 1,396,424 relates to similar handles for squash rackets.
BACKGROUND OF THE INVENTION
Connections between different elements are used within the technique to transfer forces in one or the other direction and may be fixed connections, such as a weld or a screw joint, or movable connections in the form of a bearing or a hinge. Similarly, manually used tools and implements are movably and detachably connected to the main body of the implement or tool through the medium of one or more connections or contact surfaces, for instance in the case of a knife or hammer through the medium of a single contact surface, in the case of a scythe through the medium of two contact surfaces, and in the case of a spade through the medium of three contact surfaces, and so on.
A number of different measures can be taken on eith
