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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to FIGS. 4 to 6, there is shown a releasable engaging device for engaging an engageable member. The releasable engaging device includes housing means, which may be, for example, a bracket 4, and an engageable member, such as an axle 31. The engageable member may be releasably engaged by means of locking means which may include, for example, a locking member 5, operatively connected to the bracket 4, as more fully discussed below. Thus, there is provided a wheel assembly for a golf cart according to the present invention. The releasable engaging device includes a housing or bracket 4 formed with a mounting slot 40 which extends upwardly inwardly and is equally divided by a partition 41 for firmly receiving lower end portions of two parallel legs 2 by means of rivets, a wheel set 3 having a wheel 32 rotatably mounting on an axle mechanism which has an axle 31 circumferentially formed with a an indentation or groove 312 and extending axially outwardly and a locking member 5 extending transversely into the bracket 4 and being slidably secured therein by means of a rivet 46 and forming together a releasable engagement device for releasably releasable engagement with the axle 31 so as to secure the wheel set 3 to the bracket 4.

Said bracket, or housing, 4 has a lower solid portion 47 transversely formed with a passage 42 which has a recess 43 extending from one side of the solid portion 47 so as to form an outwardly facing annular shoulder 431 near its inner end. Bores 44, 45 are formed in a side wall of the bracket 4 to define passages inwardly communicating and perpendicular to the passage 42 for respectively receiving the axle 31 and joining means such as pin-like rivet 46 wherein at least the bore 44 extends through the solid portion 47.

The locking member 5 has a key 52 in the form of a an elongated plate formed with spaced apertures or slots 521, 522 and an enlargement, head, or flange 51 attached to outer free end of the key 52 for pressing the locking member 5 to move with a finger. Apertures 521 and 522 are formed along a major axis of key 52. The first slot 521 is elongated and dimensioned to allow a relative movement between the key 52 and rivet 46 along a longitudinal direction of the key 52 and the second slot 522 is tear drop in circumferential configuration and is dimensioned to allow the axle 31 passing through the key 52 from an outer side portion 524 of larger diameter and the groove 312 of the axle 31 being engaged by an inner side portion 523 of smaller diameter.

In assembly, as best shown in FIG. 6, a resilient coil spring 53 is sleeved on the key 52 and accommodated in the recess 43, the key 52 of the locking member 5 is inserted into the passage 42 and slidably secured therein by means of the rivet 46 which extends through the bore or passage 44 of the bracket 4 and slot 521 of the key 52. The locking member 5 then can be pressed to locate the slot 522 in a position where the outer side portion 524 of the second slot 522 corresponds to the bores 45 and the wheel set 3 is secured to the bracket 4 by inserting the axle 31 thereof into bores 45 of the bracket member 4 and the slot 522 of the key 52. The axle 31 thus arranged is secured in position by the locking member 5 when the locking member 5 is released that allows the compressed coil spring 53, which is disposed between the shoulder 431 of the recess 43 and the flange 51 of the locking member 5, to bias the locking member 5 to move outwardly that resulting a firm engagement between the groove 312 of the axle 31 and the inner side 523 of the second slot 522, as best shown in FIGS. 6 & 7.

In operation for removing the wheel set 3, as shown in FIGS. 8 and 9, the flange 51 is pressed with finger to overcome biasing force of the coil spring 53 and move the locking member 5 inwardly, the inner side 523 of the second slot 522 is disengaged from the groove 312 and the axle 31 is located within the outer side portion 524, the wheel set 3 can be removed by retracting axle 31 from the bracket 4. The rivet 46 serves as a guider for locating slot 522 of the key 52 of the locking member 5 in assembly and disassembly operations of the wheel set 3.

Various changes and modifications can be made in this construction without departing from the spirit of the invention. Such changes and modifications are contemplated by the inventor and he does not wish to be limited except by the scope of the appended claims.
