Definitions

  • the present invention relates to a golf club provided with a head having an innovative structure.
  • features such as elasticity, hysteresis, mechanical strength of the head are of the greatest importance.
  • heads are made of steel or similar alloys.
  • impact characteristics such as hysteresis
  • other mechanical characteristics such as mechanical strength.
  • a golf club which comprises a cane and a head, the head being formed of a body into which a generally L-shaped insert is incorporated, said insert having the upper arm of the L projecting from the body to constitute a fastening element between the cane and head.
  • a golf club made in accordance with the invention and comprising a cane 11 and a head 12 is shown therein and generally identified by 10.
  • the head consists of a body 13 into which a generally L-shaped insert 14 is incorporated.
  • Insert 14 has the upper arm of the L 15 projecting from the head body 13 to constitute the fastening element between the cane and head.
  • arm 15 advantageously terminates with a connecting socket 16.
  • Insert 14 is made of a material having a greater mechanical strength than the material forming the body. Conversely, the body is made of a material of high hysteresis.
  • a club thus made acquires features of accuracy and throwing power that have been considered as exceptional by skilled players.
  • the insert advantageously has the L foot curved downwardly and is formed with opposite ends 17 having a bigger height than the centre. This, together with the selected materials, enables achievement of a mass concentration and a low moment of inertia for the striking energy.
  • the head body is made symmetric with respect to a transverse median plane (coincident with line III-III in Fig. 1).
  • the same casting die for the head enables right or left clubs to be obtained by merely turning the insert in the die (as shown by way of example in chain line in Fig. 1).
  • the cane is connected to the insert in such a manner as to have an extension passing through the impact centre, generally denoted at 20 (on the side opposite to the head).
  • an elliptical plate of hard material such as steel, and low thickness (1-2 mm) may be advantageously provided to be inserted centrally of the impact region, as denoted at 21 in the figures.
  • the head comprises housings 18 disposed close to the ends for receiving balancing weights 19.
  • these weights can be made in the form of a plurality of axially bored disks, packed and fastened to the inside of the housing in a removable manner (by screws, for example). If necessary, removability can be inhibited or hindered (by known systems not shown) after arrangement of the weights in an amount considered as appropriate.
  • FIG. 4 Shown in Fig. 4 is a second advantageous embodiment of a club in accordance with the invention.
  • the club generally identified by 110, has a head 112 formed of a body 113 into which an insert 14, already described above, is incorporated, the upper arm 15 of said insert terminating into the fitting socket 16 for connection with cane 111.
  • the insert advantageously has a shaped (curved, for example) central lower part to partly surround the central axis 20 of the impact region at a distance, without touching it.
  • the body 113 (still made of a material of high hysteresis, such as silver) comprises housings 118 that are embodied by holes formed in the head bottom, so that a discontinuity in the side surface of the head is not created.
  • Each hole is advantageously threaded and a correspondingly threaded and replaceable balancing weight 119 is screwed down therein.
  • the weight can also be made in the form of one or more disc-shaped inserts locked by a threaded plug 130 closing the housing.
  • the head of the plug or the threaded weight is provided with an appropriate grasping system (two small holes or grooves, for example) for carrying out untightening and tightening operations with an appropriate tool.
