DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] The drawings FIGS. 1 to 7 illustrates a first embodiment of a putter type golf grip 100 having a dual density design formed of a light weight, front topside area 102 that serves as a shaft encasing grip section and faces the golf ball when gripped by a golfer in a normal position. The grip 100 includes side sections 103 and a rear, longitudinal underside section 104. Typically, the grip 100 is molded as a unitary member or the grip can be made with separate sections that are secured together by adhesive or a similar connecting means with the sections enclosed in an outer skin 105. The golf grip 100 is formed with a closed upper butt end 106 and an opening 108 on the opposite lower end of the grip 100 to accommodate the insertion of a golf shaft into an interior bore 110 for connection thereto using adhesive or double sided tape.

[0032] In a preferred embodiment, the front topside section is made of a light material such as light weight foam material or synthetic polymer compound. The rear, longitudinal underside section 104 of the grip 100 is made with a heavier material such that the underside section 104 gravitates downwardly due to the force of gravity when the grip 100 is permitted to freely assume a rest position without manipulation by a golfer's hands.

[0033] The heavier rear, longitudinal underside section 104 is made of heavy polymer, metal or other heavy material. As shown in the sectional view of FIG. 3, the heavier rear, longitudinal underside section 104 extends from just under the closed upper butt end 106 essentially the entire distance toward and just above the lower opening 108. It will be appreciated that the heavier weighted rear, longitudinal underside section 104 may extend shorter distances between the butt end 106 and the opening 108 while functioning similarly to a longer rear, longitudinal underside section 104 depending upon the materials used.

[0034] As seen in the sectional views of FIGS. 6 and 7, the weighted rear, longitudinal underside section 104 is formed in a generally C-shaped configuration with an outer edge area having a first diameter with essentially the same parabolic shape as the outer most edge of the grip 100. The inner edge area of the C-shaped, weighted rear, longitudinal underside section 104 is formed with a second lesser diameter facing and generally conforming to the interior bore 110 of the grip 100. The weighted rear, longitudinal underside section 104 of the grip 100 is located in an area of the grip 100 that is offset furthest from the center of torque of the grip 100 where the shaft is located in the internal bore 110 with the grip 100 attached to a golf shaft. The radial distance between the center of torque and the weighted rear, longitudinal underside section 104 provides increased MOI, preventing unwanted torque of the shaft.

[0035] FIGS. 8 and 9 show a second embodiment of a golf grip 200 of the present invention. In this embodiment, a separate elongated weight member 202 is attached to a rear area of a longitudinal underside section 204 of the grip 200. The weight member 202 can be shaped to conform to and fit within a slot or other cutout portion of the 200. Alternately the weight member may be adhesively attached to the rear, longitudinal underside section 204 of the grip 200.

[0036] FIGS. 10 and 11 show a third embodiment of a golf grip 300 of the present invention. In this embodiment, a weighted rod 302 is imbedded in the rear, longitudinal underside section of the grip 300. The weighted rod 302 may be inserted in a suitable cavity formed in the grip 300 or the grip 300 may be molded around the weighted rod 302.

[0037] FIGS. 12 and 13 show a fourth embodiment of a grip with a series of individual weights 402 attached or molded directly into the rear, longitudinal underside section 404 of the grip 400. The individual weights 402 are aligned and closely spaced but are not touching each other thereby maintaining a measure of flexibility in the grip 400 prior to the attachment to the shaft of a golf putter.

[0038] It will be appreciated using a heavier rear, underside section of the grip is not limited to the precise grip shape disclosed in the above illustrations. The concept underlying the present invention can apply equally to round grips, contoured grips, oversized grips and grips with a flat alignment surface, among others.

[0039] In addition, the size and shape of the weighted section is not limited. For example, a continuous strip of heavy metal may be provided at the underside of the grip extending almost the entire length of the grip. Also, smaller weight members may be used, or a series of various sized weights may be imbedded at the underside of the grip and perform in the same way to position the rear underside of the grip in a lowermost position due to the force of gravity thereby increasing the MOI of the grip.
