ABSTRACT:
BACKGROUND OF THE INVENTION
FIELD OF APPLICATION
The present invention relates to
an assembly for releasably attaching wheels to a golf cart
a device for releasably engaging a member
.
BACKGROUND OF THE INVENTION—DESCRIPTION OF THE PRIOR ART
There are presently available
for use a wide variety of types of wheel assemblies for golf carts.
many means for the releasable attachment of a member. Such means of attachment are frequently used to attach, for example, wheel sets to a golf cart.
As shown in
FIGS. 1
to
3
, a known golf cart wheel assembly includes a bracket
1
pivotally connected to lower end of a leg
2
. The bracket
1
carries a sleeve
11
which defines a central passage extending transversely relative to the golf cart. A nut
12
is secured to a side wall of the sleeve
11
by means of welding and defines a screw passage inwardly communicating the central passage of the sleeve
11
through an opening (not shown) formed in the side wall of the sleeve
11
. A wheel
3
rotatably mounting on a stub axle
31
which is formed with a recess
311
and inserted into the sleeve
11
. Said stub axle
31
is secured in position within the sleeve
11
by means of a clamp screw
13
which extends through the nut
12
and opening in side wall of the sleeve
11
into the central passage with a protruding end thereof engaging the recess
311
of the axle. A coil spring
14
mounts between the clamp screw
13
and the nut
12
for facilitation of retracting the clamp screw
13
.
The known wheel assembly resides on the following defects:
(1) For attachments of the sleeve
11
and nut
12
to the golf cart, welding is necessary that results being labor consuming and relatively expensive in manufacture of this wheel assembly; and
(2) In mounting operation, it is time consuming that the clamp screw
13
should be threaded into the central passage of the sleeve
11
and correspondingly engaging the recess
311
of the axle
31
.
SUMMARY OF THE INVENTION
It is therefore
a primary
an
object of the present invention to provide an improved wheel assembly for a golf cart which can diminish the defects and disadvantages of a known wheel assembly.
It is another object of the present invention to provide
a wheel
an
assembly for
use with, among other types of devices,
a golf cart with an improved construction that is easy in assembly and
cheap
inexpensive
in manufacture.
With the above objectives in view, a releasable wheel assembly for golf cart includes a bracket member attached to a lower end of a leg of a golf cart, a wheel set having a wheel rotatably mounting on an axle mechanism having an axle and laterally extending into the bracket member and a locking member extending trasversely into the bracket member and being slidably secured therein by means of a rivet for releasable engagement with the axle to secure the wheel set to the bracket.
In accordance with this invention, there is provided a releasable engaging device for engaging an engageable member. The device comprises housing means. In addition there is provided locking means coupled to and movable with respect to the housing. The locking means has at least one first aperture extending therethrough to receive the engageable member. The locking means is movable from at least first to a second position with respect to said housing. With the locking means in the first position, the engageable member is freely insertable in the first aperture. With the locking means in the second position the locking means engages the engageable member so as to hold the engageable member with respect to the housing. Resilient means are provided for resiliently urging the locking means from the first position to the second position.
