ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a support of a golf cartwheel, which is provided on the lower part of the golf cart in order for a wheel to be fitted thereto to provide the golf cart with mobility.
Referring to
FIG. 4
, a heretofore known support of a golf cartwheel issued with U.S. Pat. No. 5,529,385 comprises an axle
10
and a connecting member
20
.
The axle
10
has an outer end portion provided for a wheel (not shown) to be fitted thereto and an inner end portion
101
. The inner end portion
101
has a cylindrical part
102
, a square part
103
and an annular trench
104
between the cylindrical part
102
and the square part
103
.
The connecting member
20
has a receiving hole
201
, and has a fastening cover
30
pivoted thereon. The receiving hole
201
has a round hole
202
and a square hole
203
. The fastening cover
30
has a stopping protrusion
301
.
In combination, the axle inner end portion
101
is passed into the receiving hole
201
of the connecting member
20
; the cylindrical part
102
and the square part
103
will be received in the round hole
202
and the square hole
203
respectively. The fastening cover
30
is closed on the connecting member
20
with the stopping protrusion
301
engaging the annular trench
104
in order to prevent the axle
10
from separating from the connecting member
20
.
The wheel support is found to have a disadvantage; when the golf cart is moved on an uneven place and jolts, the axle
10
will separate from the connecting member
20
very easily because the fastening cover
30
cannot secure the axle
10
very well.
SUMMARY OF THE INVENTION
Therefore, it is a main object of the present invention to provide a support for a golf cartwheel which has its parts firmly connected, and cannot fall apart easily.
The support comprises:
a holding member having two square fixing parts each having a square hole;
an axle having a first end portion provided for the wheel to be fitted thereto, and a second end portion inserted into the holding member; the second end portion having two square blocks each received in a respective one of the square holes of the holding member;
an intermediate rod portion being provided between the square blocks of the axle;
a resilient curved fastening plate pivoted on the holding member, the fastening plate being capable of being pivoted to a closed position where a curved portion and a curved protrusion thereof contacts, and engages the axle intermediate rod portion respectively to secure the axle to the holding member; in the closed position, the fastening plate being further inserted into between, and fixed by the square fixing parts of the holding member to prevent the fastening plate from separating from the axle.
