Adjustable weight golf clubs

Abstract

The present invention relates to golf clubs having a movable weight which may be used to adjust the center of gravity of the golf club head. The golf club may include a slidable weight movable to various positions along a slot between the heel and the toe of the club. The head may include a cavity shaped to receive an insert. In one embodiment, a slidable weight consisting of a screw and a weight which may engage with each other may be configured to move along the length of the insert. During assembly, the weight may be inserted into an opening in the end of the insert and slid along a close fitting channel running the length of the insert. The weight's position along the channel may be secured by engaging the screw and tightening down the screw with a portion of the insert secured between the screw head and the weight. The assembled insert and slidable weight may then be press fit into the cavity in the head. By adjusting the position of the weight and screw within the insert, the center of gravity of the golf club may be adjusted.

Description

FIELD OF THE INVENTION[0001]The present invention relates to golf clubs. More specifically, the present invention relates to golf clubs having a movable weight which may be used to adjust the center of gravity of the golf club head.BACKGROUND OF THE INVENTION[0002]When golf clubs are designed and manufactured, they are typically given specific weight characteristics to achieve performance standards that the manufacturer deems desirable for a large number of golfers. Specifically, manufacturers may wish to adjust the overall weight of the shaft of the club, the overall weight of the head of the club, the weight distribution along the shaft of the club and / or the weight distribution within the head of the club. Each change in weight has different results for different golfers depending on a golfers' height, weight, ability and swing type.[0003]Often, manufactures distribute the weight of the head of the club by casting more mass into the toe of the club, the heel of the club or both t...

However, because of the inherent differences between each golfers' size, swing and ability, this location for the sweet spot is not always ideal.

However, “custom” golf clubs are often not economically feasible for most golfers due to the cost associated with tailoring clubs to individual golfers.

Additionally, manufacturers are not able to pre-manufacture a large number of clubs for sale as the manufacturing process must account for any changes required by each individual golfer.

One drawback of previous adjustable weight clubs is that weight adjustment may be time-consuming because the weights may need to be detached and reattached or adjusted using special tools.

As such, when a golfer wishes to make a quick change or an alteration to the weight of the club (as may be desirable during pla
