Abstract

A golf club (10) comprises a head (12) consisting of a body (13) into which a generally L-shaped insert (14) is incorporated, said insert having the upper arm of the L projecting from the body to constitute a fastening element for the cane (11). The body is advantageously made of silver and the insert is made of titanium.

Description

    BACKGROUND OF THE INVENTION
  • The present invention relates to a golf club provided with a head having an innovative structure. [0001]
  • In manufacturing golf clubs, features such as elasticity, hysteresis, mechanical strength of the head are of the greatest importance. [0002]
  • Usually heads are made of steel or similar alloys. Unfortunately, impact characteristics (such as hysteresis) are substantially incompatible with other mechanical characteristics such as mechanical strength. [0003]
  • It is a general aim of the present invention to obviate the above mentioned drawbacks by providing a golf club with a head having high impact characteristics (such as high and optimal hysteresis) while at the same time showing characteristics of appropriate mechanical strength. [0004]
  • SUMMARY OF THE INVENTION
  • In view of this aim, in accordance with the invention, a golf club has been conceived 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. Still in accordance with the invention, making the body of silver material was found exceptionally advantageous. [0005]
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • For better explaining the innovative principles of the present invention and the advantages it offers over the known art, a possible embodiment applying these principles will be described hereinafter, by way of example, with the aid of the accompanying drawings. In the drawings: [0006]
  • FIG. 1 is a rear view of the head portion of a golf club in accordance with the invention; [0007]
  • FIG. 2 is a view taken along line II-II in FIG. 1; [0008]
  • FIG. 3 is a view taken along line III-III in FIG. 1; [0009]
  • FIG. 4 is a view, similar to FIG. 1, of a second embodiment applying the principles of the invention.[0010]
  • DETAILED DESCRIPTION OF THE INVENTION
  • With reference to the drawings, a golf club made in accordance with the invention and comprising a cane [0011] 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. For the purpose, arm 15 advantageously terminates with a connecting socket 16.
  • Insert [0012] 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.
  • In particular, use of silver for making the body was surprisingly found exceptionally advantageous. Thus the insert is incorporated into the casting of the silver head. Advantageous mechanical features were instead found in using titanium for making the insert. [0013]
  • A club thus made acquires features of accuracy and throwing power that have been considered as exceptional by skilled players. [0014]
  • As can be viewed from FIG. 1, the insert advantageously has the L foot curved downwardly and is formed with opposite ends [0015] 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.
  • Still advantageously, the head body is made symmetric with respect to a transverse median plane (coincident with line III-III in FIG. 1). In this manner, 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). [0016]
  • As diagrammatically shown 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 [0017] 20 (on the side opposite to the head).
  • To protect the silver surface against repeated impacts with the ball, 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 [0018] 21 in the figures.
  • In an improved embodiment, the head comprises housings [0019] 18 disposed close to the ends for receiving balancing weights 19. As well apparent from the figures these weights (of a material of convenient mass) 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.
  • At this point it is apparent that the intended purposes have been achieved by providing a club having high impact and mechanical characteristics that are deemed greatly satisfactory by those skilled in the art. [0020]
  • Obviously the above description of an embodiment applying the innovative principles of the present invention is given by way of example only and therefore must not be considered as a limitation of the scope of the patent rights herein claimed. For example, the exact conformation of the head may vary depending on specific technical and aesthetic requirements and on the desired club type. [0021]
  • Shown in FIG. 4 is a second advantageous embodiment of a club in accordance with the invention. The club, generally identified by [0022] 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. As in the preceding embodiment, 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.
  • In the embodiment in FIG. 4, the body [0023] 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. As shown in chain line in the right-hand housing 118, 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.
