Publication number: 20070044880Abstract: A tire for a golf cart includes an inner tire, and a thin outer tire mounted around the inner tire. The inner tire made of EVA solid foam material co-operates with the thin outer tire having a plurality of protruding bosses to construct a solid composite tire, so that the tire has a light weight, needs not to be inflated and has a better shock-absorbing effect. In addition, the pointed cylindrical shaped protruding bosses of the thin outer tire can be extended into the muddy or snowy ground to provide an excellent grip effect, so that the golf cart can be moved smoothly and conveniently. Thus, the tire has an excellent ground grip effect, so that the tire is available for the muddy or snowy ground.Type: ApplicationFiled: September 1, 2005Publication date: March 1, 2007Applicant: Unique Product & Design Co., Ltd.Inventor: Gordon Liao

Patent number: 7000928Abstract: A third wheel collapsing device for a golf club cart includes a third wheel support frame having a U-shaped frame fixed pivotally with a third wheel and a hollow support arm fitted therein with a fit block. The support arm and the fit block respectively have insert holes and connecting holes. A support base assembled on the support arm has a pivotal shaft under the bottom and a threaded hole before the pivotal shaft for receiving an elastic lock member, which has an engage rod biased by a compression coil spring and controlled by a user. The support base has a fastening frame fixed with the lower end of the main frame of a golf club cart. When the engage rod is pulled and removed from the first insert hole of the support arm and the first connecting hole of the fit member, the third wheel support frame can be transversely collapsed.Type: GrantFiled: December 3, 2003Date of Patent: February 21, 2006Assignee: Unique Product & Design Co., Ltd.Inventor: Gordon Liao
