Abstract
A foldable golf cart includes a main support rod, a pair of wheel support rods, a connecting members, two connecting rods and a handle. The wheel support rods are pivoted to an intermediate portion of the main support rod, and each connected to a wheel. The connecting member is connected to an upper end of the main support rod. The handle is pivoted to an upper end portion of the main support rod. The connecting rods are each pivoted to the handle from one end, and pivoted to a respective one of the wheel support rods from other end. The handle has hooked portions separately engaging a depressing block of the connecting member. The handle is pivoted down to a folded position; thus, the connecting rods will at the same time move the wheel support rod to a folded position. The handle is pivoted upwards to an upright unfolded position; thus, the connecting rods will move the wheel support rods to an unfolded position. The depressing block fixes the handle in the upright position by engaging the hooked portion of the handle. The depressing block is disengaged from the hooked portion when depressed.
Description
BACKGROUND OF THE INVENTION
The present invention relates to a foldable golf cart which can be easily folded to a smaller size for storage.
Foldable golf carts are convenient to use. There are many kinds of foldable golf carts available in the market. However, some of them are not very convenient to fold.
SUMMARY OF THE INVENTION
Therefore, it is a main object of the present invention to provide a foldable golf cart which can be folded in a very simple way.
The foldable golf cart of the present invention includes
a main support rod member;
a pair of wheel support rods; the wheel support rods being pivoted to the intermediate part of the main support rod member;
two wheels; the wheels being each fitted to a respective one of the wheel support rods;
a connecting member; the connecting member being connected to an upper end portion of the main support rod member; the connecting member having a depressing block movably received in a holding room of the connecting member; the depressing block having two locking rods on two sides thereof; the depressing block is biased upwardly of the holding room by a spring;
a handle; the handle having two hooked portions and a lower end portion; the handle lower end portion being pivoted to the upper end portion of the main support rod member; the hooked portions being passed into the holding room of the connecting member, and engaging a respective one of the locking rods of the depressing block to fix the handle when the handle is pivoted to an upright position; the depressing block being capable of be depressed for the locking rods to be disengaged from the hooked portions of the handle; permitting the handle to be pivoted down to a folded position;
two connecting rods; the connecting rods being each pivoted to the handle from one end, and pivoted to a respective one of the wheel support rods from other end; the connecting rods can move the wheel support rods to a folded position when the handle is pivoted down, and can move the wheel support rods to an unfolded position when the handle is pivoted up to the upright position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 1
,
2
and
3
, a foldable golf cart of the present invention includes a main support rod
10
, wheel support rods
20
, wheels
30
, a handle
40
, a pair connecting rods
50
and a connecting member
1
.
The wheel support rods
20
are pivoted to intermediate portions of the main support rods
10
. The wheels
30
are fitted to outer ends of the wheel support rods
20
. The connecting member
1
is connected to upper ends of the main support rods
10
. Referring specifically to
FIG. 3
, lower end portions of the handle
40
are pivoted to the main support rods
10
. The connecting rods
50
are each pivoted to a respective one of the lower end portions of the handle
40
from an upper end of the connecting rod
50
, and pivoted to a respective one of the wheel support rods
20
from a lower end portion of the connecting rod
50
such that the connecting rods
50
can move the wheel support rods
20
between a stretched in-use position and a folded not-in-use position when the handle
40
is pivoted on the main support rod
10
.
Referring to
FIGS. 2 and 3
again, the connecting member
1
has a holding room
2
defined by a wall (not numbered) on an upper side thereof. The wall has two openings
21
and two through holes
22
. Two locating protrusions
23
are formed within the holding room
2
on the connecting member
1
. The connecting member
1
further has a depressing block
3
. The depressing block
3
has two receiving holes
33
, two elongated holes
32
and two locking rods
31
each on one side of the depressing block
3
. The depressing block
3
is movably received in the holding room
2
of the connecting member
1
with springs
4
inserted into the receiving holes
33
from upper end portions of the springs
4
. The locating protrusions
23
are each inserted into a respective one of the springs
4
from lower end portions of the springs
4
. Thus, the depressing block
3
is biased upwardly by the springs
4
. Each of the through holes
22
and a corresponding one of the elongated holes
32
of the depressing block
3
have a bolt
5
passed therethrough such that the depressing block
3
will not falling off the holding room
2
.
The locking rods
31
each communicates with a respective one of the openings
21
of the wall of the holding room
2
. The handle
40
has hooked portions
6
on the lower end portions. Referring specifically to
FIG. 3
, the hooked portions
6
each passes through a respective one of the openings
21
and engages a respective one of the locating rods
31
of the depressing block
3
to locate the handle
40
when the handle
40
is pivoted on the main support rods
10
upwards to an upright position; when the handle
40
is pivoted to the upright position, the wheel support rods
20
will be stretched to the in-use position by the connecting rods
50
.
In folding the golf cart, referring to
FIGS. 4
,
5
, and
6
, first tile depressing block
3
is depressed to disengage the lock rods
31
of the depressing block
3
from the hooked portions
6
of the handle
40
. Then, the handle
40
is pivoted downwards until the handle
40
is disposed adjacent to the main support rod
10
; the connecting rods
50
will at the same time move the wheel support rods
20
to the folded not-in-use position. Thus, the golf cart is folded.
When the handle
40
is pivoted back to the upright position, and hooked portion
6
will engage the locking rods
31
of the depressing block
3
again to fix the handle
40
in position.
The connecting member
1
of the present invention can also be used in a golf cart which has a single main support rod and a handle made of a single rod.
From the above description, the foldable golf cart can be known to be able to be folded and stretched very fast and easily.
