ABSTRACT:

The present invention relates generally to an improved leg mechanism attachment to a golf bag, the leg mechanism improvement more particularly contributing to greater ease and effort in using the leg mechanism to provide a tripod support for the golf bag.
EXAMPLE OF THE PRIOR ART
It is well documented in the patented literature that playing golf is greatly facilitated if the golf bag containing the golf clubs not in use is supported in an upright condition while the golfer is using the golf club selected from the golf bag appropriate for the golf shot at hand. The prior art support of choice is one assuming a tripod configuration in which left and right legs are urged through pivotal traverses into angular positions which are effective to steady the golf bag positioned therebetweeen.
Exemplifying the patent literature is U.S. Pat. No. 5,634,616 for “Removable Automatic Tripod Legs For Golf Bags” issued to Wang et al. on Jun. 3, 1997. In the '616 patent and all other known patents, the leg-opening mechanism uses cranks operated by a wire spring which, in response to ground contact, causes a rotation of the cranks which, in turn, impart corresponding rotational traverses to the legs. To this end, the spring has a Y-shape and each upper leg of the Y is attached to a cooperating crank, while the bottom leg is used to make ground contact and impart an ascending movement to the spring. While generally useful for the purposes intended, the operational mode as just generally described of the prior art leg mechanism do not operate with optimum case and effort, as can be verified by the upper Y-shape legs manifesting a noticeable bow configuration between their attachment to the cranks and to their extension from the bottom ground-engaging leg. Stated somewhat differently, the force producing the bending of the upper legs of the spring is better used in rotating the cranks, and this is not achieved in the prior art legopening mechanisms.
Broadly, it is an object of the present invention to provide a golf bag tripod support overcoming the foregoing and other shortcomings of the prior art.
More particularly, it is an object to provide a golf bag leg-opening construction which has a leg-opening operating mode which is implemented with a mechanical advantage, to thereby contribute to greater ease and optimum minimum effort in its use.
