For the above configuration guide means, the securing means may include a securing screw for each guide rod, each screw being displaceable within the second head part into abutment with its guide rod for securing the location of the second head part on the guide rods. More particularly, each guide rod defines a set of peripheral grooves within a segment along the length thereof, each groove being engageable by the end of a securing screw for locating the second head part on the guide rods in different locations and for providing a mechanical lock between the guide rods and the securing screws that lock the position of the second head part on the guide rods.
a putter shaft having one end secured to the putter head via the shaft securing formation thereof and having a grip located on the other end thereof. The putter head of the golf putter of the invention particularly includes all the features of the putter head, in accordance with the present invention.

Figure 7 shows a three-dimensional view of an alternative embodiment first head part for the putter head as shown in Figure 1.
Referring initially to Figures 1 to 6 of the drawings, a putter head for a golf putter, in accordance with the invention, is designated generally by the reference numeral 10. The putter head 10 includes a first head part 12 and a second head part 14, the two head parts being displaceably located with respect to one another in a configuration as described hereafter.
The first head part 12 defines also a rear face 20, that is disposed parallel to and rearwardly spaced from the striking face 16. Two elongate guide rods 22 serve to guide displacement of the second head part 14 with respect to the first head part 12 as described hereafter, particularly along a line extending substantially perpendicularly to the striking face 16 defined by the first head part 12. More particularly, the first head part 12 defines two threaded bores 24 on the operative rear face side 20 thereof, the guide rods 22 defining threaded leading ends 26 that can operatively screw into the respective bores 24. When screwed into the bores 24, the guide rods 22 will be axially aligned with the said line extending substantially perpendicularly to the striking face 16 defined by the first head part 12. The second head part 14 is slidably located on the guide rods 22 via suitable guide passages 28 that are defined therethrough, thus providing for sliding displacement of the second head part 14 on the guide rods 22. The two head parts particularly are displaceable with respect to one another between a first position, in which the operative front face 30 of the second head part 14 abuts against the operative rear face 20 of the first head part 12 and a plurality of positions in which the two head parts are spaced apart (see respectively Figures 5 and 6 of the drawings).
As is clearly illustrated in Figure 2 of the drawings, each guide rod 22 defines a set of peripheral grooves 32 therein along a segment of the length thereof. The putter head 10 includes also two securing screws 34, each screw being displaceable in a complementary threaded passage 36 defined therefor within the second head part 14, so that the leading end of the securing screw 34 can be displaced into abutment with one of the guide rods 22 and particularly into mechanical engagement with one of the peripheral grooves 32 in the guide rod 22. As such, the second head part 14 can be mechanically locked in different positions with respect to the first head part 12, with its position being determined by the location of the peripheral grooves 32 with respect to the securing screws 34, i.e. being determined by the position of the second head part 14 on the guide rods 22.
Referring particularly also to Figures 3 and 4 of the drawings, the first head part 12 of the putter head 10 has a shaft securing formation, for securing a shaft to the putter head, formed within the rear face 20 thereof. The shaft securing formation includes particularly a circular recess 38 which is located midway between opposite ends of the first head part 12 and two sets of three equally spaced threaded bores 40, extending further into the first head part 12 from the base of the recess 38.
Referring now particularly to Figure 3 of the drawings, with the shaft engagement formation 48 orientated with respect to the first head part 12 in the configuration as shown, the shaft engagement formation 48 can be secured to the first head part 12 by means of three securing screws 52 that can screw into one of the sets of threaded bores
40 and engage the disc-like body 44, to thereby secure its location with respect to the first head part 12. As is clear from the drawing, by the angular displacement of the shaft engagement formation 48 between limits determined by the slot-like apertures 46 defined in the body 44, the angular position of the shaft engagement formation 48 and, therefore, a shaft secured thereto, can be adjusted, thus to accommodate particular golfer requirements. The limits of adjustment particularly are determined by formal rules that are associated with the design of golf putters and that require there to be a particular angular relationship between the shaft of a golf putter and its associated putter head.
The angular relationship between a putter shaft secured to the shaft engagement formation 48 and the first head part 12 of the putter head 10 as shown in Figure 3 particularly accommodates putting by right handed golfers. In order to accommodate putting by left handed golfers, the shaft engagement formation 48 can be displaced to a range of angular positions as determined by the slot-like apertures 46 in relation to their position with respect to the second set of threaded bores 40, the mode of angular adjustment of the shaft engagement formation 48 and, therefore, of a shaft, with respect to the first head part 12, being effected merely by loosening and fastening of the securing screws 52. The particular relationship between the slot-like apertures 46 and the two sets of threaded bores 40 is such that only "legal" angular relationships are permitted, as determined by the formal rules that are associated with the design of golf putters, although accommodating particularly both left handed and right handed golfers.
As is clearly illustrated particularly also in Figures 5 and 6 of the drawings, the second head part 14 of the putter head 10 is profiled to define a space 54 between the two head parts, 12 and 14, which space is disposed centrally behind the centre of the first head part 12 and which thus serves to accommodate the location of the shaft engagement formation 48 with respect to the putter head. The space 54 also is located centrally behind the centre of percussion defined by the striking face 16 as referred to above, this space thus serving also to provide for a desired mass distribution of the second head part 14 behind the first head part 12.
Insofar as the overall mass and the mass distribution associated with a putter head is considered very important to particular golfers, the displacement of the first head part 12 and the second head part 14 of the putter head 10 serves to accommodate various such requirements. It is further envisaged in this regard that the putter head 10 may be provided with additional pairs of guide rods that are selectively interchangeable with the guide rods 22, the additional guide rods being formed of different materials and of a different mass, so that through interchanging guide rods, further requirements of particular golfers can be accommodated. Although it is envisaged that a particular pair of guide rods used would usually have the same mass, it is envisaged in this regard that a pair of guide rods can be used where the rods have a different mass to one another, thus altering the mass distribution on the operative toe end and heel end of the putter head. In practice, this can reduce a tendency by a golfer to either push/slice a putt orto pull/hook a putt.
The putter head of the invention further may be associated with various other features that are commonly associated with known putters in order to provide a putter with different putting characteristics, it being envisaged, for example, that either one or both parts of the putter head can be associated with removable mass inserts that can still further accommodate mass and mass distribution requirements of a golfer in relation to the putter head. Clearly, the two head parts of the putter heads can be formed of the same or different materials, while different configuration striking faces also can be provided for. For example, the striking face 16 of the first head part 12 of the putter head 10 as described is a milled face, whereas, as shown in Figure 7 of the drawings, the first head part 60 of a putter head may have a striking face 62 defined by an insert element 64 that is located within a recess 66 provided therefor in the front face side of the first head part 60, the insert element providing the associated putter head with particular striking characteristics. Clearly, the putter head of the invention as described can accommodate numerous other requirements of a golfer in this regard.
