Description
FRONT WHEEL ADJUSTING DEVICE FOR A GOLF
CART
BACKGROUND OF THE INVENTION
This invention relates to a front wheel-adjusting device for a golf cart, particularly to one able to adjust an angle of the front wheel of a golf cart so as to enable it to run straightforward without being influenced by the topography of a golf course.
Generally, a golf cart has a front wheel and two rear wheels. The front wheel,, as shown in Figs. l and 2, includes a U-shaped support frame 20 and a front wheel respectively fixedly assembled with a golf cart 10.
The front wheel 30 fitted between the two parallel rods of the support frame 20 is pivotally assembled with the support frame 20 for rotating by means of a threaded rod 301 inserted through the shaft holes of the support frame and the front wheel 30 and then locked. However, after used for a period of time, the unadjustable front wheel is liable to become deflected and unable to keep running straightforward in case a golf course is uneven.
SUMMARY OF THE INVENTION
The objective of this invention is to offer a front wheel-adjusting device for a golf carts able to adjust the front wheel of a golf cart and keep it running straightforward, regardless of the topography of a golf course.
The front wheel-adjusting device for a golf cart in the present invention includes a U-shaped support frame and a front wheel fitted between two parallel rods of the support frame. The two parallel rods of the support frame have their ends respectively formed with a hollow interior and bored with a vertical groove in the inner side. The front wheel has its shaft hole inserted with a shaft which has its opposite ends protruding out of the shaft hole and respectively bored with a through inner threaded hole. The shaft has its opposite ends respectively fitted with a fixing member which is bored with a slide groove in one side facing the front wheel and a lengthwise through hole aligned to the inner threaded hole of the shaft. Thus, the two fixing members are respectively fitted with the outer ends of the shaft, letting the opposite ends of the shaft respectively located in the slide grooves of the two fixing members Then, a properly long threaded rod is inserted upward through the lengthwise through hole of the fixing member and the inner threaded hole of the shaft, and then extending out of the topside of the fixing member and screwed with a nut. Next, the two fixing members are respectively stuffed into the two parallel rods of the support frame and fixed therein by bolts, letting the opposite ends of the shaft respectively positioned in the vertical grooves of the two parallel rods of the support frame. Thus, the opposite ends of the shaft are able to move up and down horizontally along the threaded rod to adjust the front wheel of a golf cart by turning around the threaded rod.

DETAILED DESCRIPTION OF THE PREFERRED
EMBODIMENT
A preferred embodiment of a front wheel-adjusting device for a golf cart in the present invention, as shown in Fig. 3, includes a U-shaped support frame I and a front wheel 2 as main components combined together.
The support frame I is formed with two parallel rods 11 having their ends respectively formed with a hollow interior and bored with a vertical groove t 11 in the inner side.
The front wheel fitted between the two parallel rods 11 of the support frame I has a shaft hole 21 for a shaft 22 to insert, which has its opposite ends respectively protruding out of the shaft hole 21 and bored with a through threaded hole 221. Two fixing member 23 are respectively fitted with the outer ends of the shaft 22, respectively having a slide groove 231 in one side facing the front wheel 2. Each fixing member 23 has a lengthwise straight groove 232 aligned to the threaded hole 221 of the shaft 22 and a recessed chamber 233 formed integral under the straight groove 232.
In assembling, as shown in Fig 4, firstly, the shaft 22 is inserted in the shaft hole 2 t of the front wheel 2 and has its opposite ends with the inner threaded holes 221 respectively protruding out of the shaft hole 21.
Next, the two fixing members 23 are respectively fitted with the outer ends of the shaft 22, letting the two inner threaded holes 222 in the opposite ends of the shaft 22 respectively located in the slide grooves 231 of the fixing members 23. Then, a properly long threaded rod 24 is inserted upward in the lengthwise straight groove 232 of the fixing member 23 and the inner threaded hole 221 of the shaft 22 and then extending out of the topside of the fixing member 23 and screwed with a nut 241, letting the head of the threaded rod 24 received in the recessed chamber 233 of the fixing member 23.
Subsequently, the two fixing members 23 are respectively stuffed into the two parallel rods 11 of the support frame I and fixed therein by bolts 112, letting the opposite ends of the shaft 22 respectively fitting in the vertical grooves 111 of the parallel rods 11 to finish assembly of the front wheel adjusting device. Lastly, the finished front wheel-adj usting device has the support frame 2 assembled on the front end of the framework of a golf cart 3, as shown in Fig. 5.
In using, after the golf cart 3 is used for a period of time, and its front wheel becomes deflected and unable to go straightforward, only turn around the threaded rod 24 with a simple tool (like an inner hexagonal spanner) to let the threaded rod 24 rotate idly in the through hole 232 of the fixing member 23 and actuate the shaft 22 to move up and down horizontally along the threaded rod 24, as shown in Fig. 6, because the inner threaded hole 221 in the opposite ends of the shaft 22 are meshed with the threaded rod 24.
Synchronously, the shaft 22 actuates and adj usts the front wheel of the golf cart 3 to a correct angle to enable the golf cart to go straightforward again.
While the preferred embodiment of the invention s has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention. 1 0
