Abstract
A wheel supporter and shaft for a golf cart includes a wheel shaft having an end portion protruding out of a wheel. The protruding end portion is formed with two opposite recesses respectively provided with a curved projection. The wheel supporter has a shaft hole for the wheel shaft to fit therein, and an eccentric push member is pivotally connected under a bottom wall of the shaft hole. The eccentric push member has two round projections to protrude in the shaft hole to engage a space between each recess and each curved projection so that the wheel supporter may be locked with the wheel shaft in a stabilized condition with easy handling.
Description
TITLE: WHEEL SUPPORTER AND SHAFT FOR A GOLF CART
BACKGROUND OF THE INVENTION
This invention relates to a wheel supporter and a shaft for a golf cart, particularly to one having a simple structure for easy assemblage and collapsing.
Conventional golf carts are generally made collapsible, with a wheel supporter and shaft capable to be collapsed and assembled by a user, so as to be easily carried with a small dimensions or stored in a car trunk after collapsed.
Nowadays, there are two kinds of conventional wheel supporters and shafts for a golf cart.
A first kind of conventional wheel supporter and shaft is shown in Figs. 1 and 2, including a wheel supporter 1 consisting of a metal plate unit 11. The metal plate unit 11 has a pin 35 to pivotally connect a recover spring 34 and a push member 3, a shaft hole 111 for a shaft 21 of a wheel 2 to insert therein. The push member 3 has a projecting pointed member 31 in an intermediate portion, a groove 32 under the pointed member 31, and an engage plate portion 33 formed in an upper portion. The recover spring 34 has one end hooked on the metal plate unit 11, and the other end hooked at a middle point of the push member 3, controlling engagement and disengagement of the groove 32 of the push member 3 and an annular groove 211 of the shaft 21.
This conventional wheel supporter and shaft is convenient in handling, but its structure is a little complicated for assembly or collapsing.
The second kind of conventional wheel supporter and shaft is shown in Figs. 3 and 4, including a wheel supporter 10, which has a rectangular opening 14 and an insert hole 12, a coil spring 13 contained in the opening 14, and an engage block 5 elastically urged by the coil spring 13 and normally located in the opening 14 to be able to be half pushed out of the opening 14. The engage block 5 has a protruding hook 51 in a left longitudinal side of an outer block portion engaging an inner wall of the opening 14, and an L-shaped position hook 52 with a sloped surface extending inward from the outer block portion. A wheel shaft 4 has one end firmly connected to a wheel 20 and the other end portion 41 formed with a distal square end 43 facing the sloped surface of the L-shaped position hook 52 of the engage block 5 located in the wheel supporter 10, and an intermediate groove portion 42 to engage the L-shaped position hook 52.
In handling the second conventional wheel supporter and shaft, the wheel shaft 4 is inserted in the insert hole 12 of the wheel supporter 10, with the other end portion of the wheel shaft 4 engaging the L-shaped position hook 52 of the engage block 5, finishing assemblage of the wheel supporter 10 with the wheel shaft 4. On the contrary, if the wheel shaft 4 is to be pulled out of the wheel supporter 10, the push block 5 is pushed up (in Fig. 4, or inward) to compress the coil spring 13, forcing the L-shaped position hook 52 disengage from the other end portion 41 of the wheel shaft 4 to free the wheel shaft 4 from the wheel supporter 10.
However, the second conventional wheel supporter and shaft is also handy to handle, but its structure is also complicated for assembly and collapsing.
SUMMARY OF THE INVENTION
The purpose of the invention is to offer a wheel supporter and shaft for a golf cart, having a simpler structure than the conventional ones for easy assemblage and collapsing.
According to the present invention, there is provided a wheel supporter and shaft for a golf cart comprising:
a wheel supporter and a wheel shaft, said wheel shaft having one end portion protruding out of a wheel, said protruding end portion is formed with two recesses therein, each said recess having a curved projection, said wheel supporter having a shaft hole to receive said wheel shaft, an eccentric push member is located under a bottom wall of said shaft hole, said eccentric push member having two round projections that protruded in said shaft hole, each said round projection engages a space between a respective one of said recesses and a respective one of said curved projections so that said wheel supporter is locked with said wheel shaft, the eccentric push member being swingingly pushable down to force the two round projections into a disengagement from the recesses and the curved projections while the wheel shaft is pulled out of the shaft hole, the wheel supporter being then disengaged from the wheel shaft.

3a DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A preferred embodiment of a wheel supporter and shaft for a golf cart in the present invention, as shown in Figs. 6 and 7, includes a wheel shaft60 having a round end to fix firnily with a wheel 6 and the other end protruding out of a wheel 6 and shaped rectangular and having two opposite recesses 61 of smaller size than the rest portion and a curved projection 62 formed in each recess 61. A wheel supporter 7 has a rectangular shaft hole 71 formed in a lower end for the wheel shaft 60 to fit therein, a pivotal base 72 formed in a bottom wall defining the shaft hole 71, a groove 73 for-med respectively at two sides of the pivotal base 72 for pivotally connecting an eccentric push member 8 with a pin shaft 74. The eccentric push member 8 has two projecting ears 81 formed in an upper portion, and a round projection 82 respectively formed on an inner side of each ear 81 to pass through the grooves 73 and extend in the shaft hole 71, and a cuived push means 83 formed in the other end portion.
In assembling the wheel supporter 7 with the wheel shaft 60, firstly insert the wheel shaft 60 together with the wheel 6 in the shaft hole 71 of the wheel supporter 7, with the two opposite recesses 61 just facing the grooves 73. Then pull backward the eccentric push member 8 as shown with an arrow head in Fig. 7, forcing the two round projections 82 extend in the recesses 61, slide over the curved projections 62 and engage the space between each projection 62 and the each recess 61, securing the wheel supporter 7 with the wheel shaft 60, as shown in Figs. 8 and 9.
On the contrary, if the wheel supporter 7 is to be disengaged from the wheel shaft 60, only push swingingly down the eccentric push member 8, forcing the two round projections 82 disengage from the recesses 61 and the projections 62, with the wheel shaft 60 pulled out of the shaft hole 71, ~
as shown in Figs. 7.
It has to be noted that the protrucling end portion of the wheel shaft 60 protruding out the wheel 6 may gradually enlarged to the rear portion in corresponding to the hole 71 also gradually enlarged to the rear portion so that the wheel shaft 60 may easily fit in the shaft hole 71, as shown in Fig.
7.
As can be understood from the aforesaid description, the wheel supporter 7 may be disengaged from the wheel shaft 60 only by pulling or pushing the eccentric push member 8, which is a very simple structure for handling.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended clairns are intended to cover all such modifications which may fall within the spirit and scope of the invention.
