Golf cart umbrella holder

A golf cart umbrella holder comprising a mounting device fastened to the frame of a golf cart by a screw, a clamping device fastened to the mounting device by a screw to hold a socket for holding an umbrella. The clamping device has teeth on a contact wall to the mounting device around a circle respectively meshed with teeth on the mounting device. By changing the meshing order between the teeth on the mounting device and the teeth on the clamping device, the angular position of the umbrella relative to the golf cart is adjusted.

BACKGROUND AND SUMMARY OF THE INVENTION 
The present invention relates to a golf cart umbrella holder for holding an 
umbrella on a golf cart. 
The golf is an outdoor game in which a player using special clubs attempts 
to sink a ball with as few strokes as possible into each of the 9 or 18 
successive holes on a course. While playing on the course, the players may 
be suffering the beating of the weather. Therefore, a golf player may hold 
or ask a caddie to hold an umbrella for protection against the sun or 
rain. However, it is not convenient to carry an umbrella by a golf player 
oneself. 
The present invention has been accomplished under the aforesaid 
circumstances. It is therefore an object of the present invention to 
provide a golf cart umbrella holder which can be conveniently fastened to 
the frame of any of a variety of golf carts for holding an umbrella. It is 
another object of the present invention to provide a golf cart umbrella 
holder which can be conveniently adjusted to change the angular position 
of the umbrella on a golf cart. 
To achieve these objects, there is provided a golf cart umbrella holder 
which is generally comprised of a mounting plate fastened to the frame of 
a golf cart by screw means, a clamping device fastened to the mounting 
device by screw means to hold a socket for holding an umbrella. The 
mounting device is comprised of two symmetrical plates having each a 
channel through respective inside wall which receives the frame of a golf 
cart. The channel has a V-groove and two chamfered opposite top edges 
which make the mounting plate applicable for fastening to any of a variety 
of golf cart frames. The clamping device has teeth on a contact wall to 
the mounting device around a circle respectively meshed with teeth on the 
mounting device. By changing the meshing order between the teeth on the 
mounting device and the teeth on the clamping device, the angular position 
of the umbrella relative to the golf cart is adjusted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to FIGS. 1 and 2, a golf cart umbrella holder as constructed in 
accordance with the present invention is generally comprised of a mounting 
device 1 fastened to the frame 91 of a golf cart 9 to hold a socket 6 by a 
clamping device 2 for holding an umbrella 8. The mounting device 1 is 
consisted of two symmetrical plates 11, 12 each having a channel 111 or 
121 on an inside wall thereof, which channel 111 or 121 has a V-shaped 
groove 1111 or 1211 centrally arranged in the in longitudinal direction, a 
flat bottom with square corners and two chamfered peripheral top edges 
1112 or 1212. At least one of the symmetrical plates 11, 12 has a 
plurality of teeth 1141 on an outside wall thereof around a circle. The 
clamping device 2 has an opening 23 which receives the socket 6, and a 
plurality of teeth 2142 on a peripheral wall thereof around a circle. The 
socket 6 fits the opening 23 on the clamping device 2 and has a tapered 
bore 61 through the central axis thereof. 
Referring to FIGS. 3A, 3B, 3C, 3D and seeing FIG. 2 again, by means of the 
arrangement of the V-shaped grooves 1111, 1211 and the chamfered edges 
1112, 1212, the two symmetrically plates 11, 12 can be conveniently 
tightly fastened to any of a variety of golf cart frames 91 by screw bolts 
3, 7. Once the mounting device 1 has been fastened to the frame 91 of a 
golf cart 9, the clamping device 2 is fastened to the mounting device 1 by 
a screw bolt 5 with the teeth 1141, 2142 meshed or mated, to hold the 
socket 6 in the opening 23. By inserting the handle 81 of an umbrella 8 in 
the tapered boring bore 61 on the socket 6, the umbrella 8 is supported on 
the frame 91 of the golf cart 9 for protection against the sun or rain. 
By changing the meshing order between the teeth 1141 on the mounting device 
1 and the teeth 2142 on the clamping device 2, the angular position of the 
umbrella 8 relative to the golf cart 9 is adjusted.
