Abstract

A golf cart wheel positioning structure is disclosed generally consisting of a wheel (1), a bearing (2) inserted in the wheel center (11) of the wheel (1), an axle sleeve (3) inserted into the bearing (2), a lug (4) mounted on the frame of a golf cart, and a wheel axle (5) mounted on the lug (4) and inserted into the axle sleeve (3). When the wheel axle (5) is inserted into the axle sleeve (3), the retaining ribs (411) of the hollow flange (41) of the lug (4) are respectively meshed with the retaining grooves (321 ) of the shaft sleeve element (3) and the tenons (45) of the tab (4) are inserted into the through hole (332) of the extension (331) and the flap (7) of the tab (4) is rotated to abut the extension (331) to strengthen the connection.

Description

This invention relates to a position structure

golf cart wheel wheel.

  A normal golf wheel, as illustrated in FIG. 1, has a wheel center 11 ′ for the insertion inside of this of a bearing 2 ′ into which a wheel axle (not shown) is inserted and firmly held in place with a 3 'screw As positioning

  is made by connecting the wheel axle with the wheel

  lement and locking the screw 3 ', the screw 3' tends to unscrew and the wheel 1 'can become unstable or

escape from the wheel axle.

  Therefore, the main purpose of this

  invention is to provide such a posi structure

  golf cart wheel actuation in which the axle sleeve is firmly connected to the frame of the cart by means of a lug through the engagement of grooves

  support with support ribs and in

  tenon with a through hole.

  Another object of the present invention is to pro-

  curing such a golf cart wheel positioning structure in which the engagement of the lug

  the tab with the extension through hole is closed

  Supported by means of a flap which pivots on the leg. According to the present invention, a golf cart wheel structure generally comprises a wheel, a bearing inserted in the center of the wheel, and an axle sleeve which is inserted inside the bearing and which comprises

  carries an element comprising a defined internal hole-

  sant inside thereof a plurality of retaining grooves and which comprises outside an extension having thereon a through hole, a tab being mounted on the frame of a golf cart and comprising at

  top a hollow flange having on it, outside

  laughing, a plurality of retaining ribs and

  both at the base a lug, and a wheel axle mounted on the hollow flange of the lug and inserted inside the axle sleeve When the wheel axle is inserted in the axle sleeve, the retaining ribs hollow flange

  of the tab are respectively meshed with the enco-

  retaining pins of the axle sleeve element and the lug tenon is inserted into the through hole of the extension and the lug flap is turned so

  to abut against the extension in order to reinforce the

nexion.

  An embodiment of the present invention goes to-

  can be described by way of example with reference to the accompanying drawings, in which: Figure 1 is a perspective structural view of the existing technique; Figure 2 is a fragmentary perspective view of the present invention; and Figure 3 is a schematic overview in

section of the present invention.

  If we refer to the different attached drawings,

  a detailed description of the structural characteristics

  rales of a wheel positioning structure

  The golf riot of the present invention is as follows. Referring now to the accompanying drawings,

  detail, we find here illustrated a structure of posi-

  golf cart wheel actuation representing the present invention and generally composed of a wheel 1, a bearing 2 and a shaft sleeve 3, a lug 4, and

a wheel axle 5.

  The shaft sleeve 3 has at the rear end an element 31 made in one piece by a shaping process The element has an internal hole 32 defining inside thereof a plurality of grooves support 321, and two raised parts

  opposite 33 and 34 made on the outer wall surface

  lower, namely a lower raised part 33 and an upper raised part 34 The lower raised part 33 is made in one piece with an extension 331 arranged horizontally along the axial direction opposite to the sleeve of axis 3, which extension 331 has a through hole 332 made on

this one at the front end.

  The lug 4 is fixedly mounted on the frame of a golf cart and comprises a hollow flange 41 which is an integral part thereof, in which is inserted the wheel axle 5 The hollow flange 41 has a plurality of retaining ribs 441 made so

  equiangular on the outer wall surface available

  seated horizontally along the axial direction (in the present embodiment, the retaining ribs 411 form a cross structure), which raised retaining ribs 411 have, suitably, a size which corresponds to that of the retaining grooves 321 of the element 31, which means that when the flange 41 of the tab 4 is inserted into the internal hole 32 of the shaft sleeve 3, the retaining ribs 411 become respectively meshed with the retaining grooves 321 so as to resist twisting force

  4 further comprises two parts 42 and 43 of side walls

  Opposite rails extending vertically downwards, having a pivot hole 420 made respectively thereon for the insertion through it of a locking pin 6 so as to pivot a flap 7 towards the tab 4, which flap 7 has one end

  extending forward 71 spaced from the lower surface

  lower leg 4 within a certain range so as to define therewith a door 44 suitable for the insertion through it of the extension 331 of the

axle sleeve 3.

  When assembled, the shaft sleeve 3 is sim-

  insert inserted into the inside diameter of the bearing 2 after the bearing 2 has been inserted in the center 11 of the wheel 1 After having been mounted on the hollow flange 41 of the lug 4, the wheel axle 5 as well as the flange 41 of the tab 4 are inserted into the internal hole 32 of the shaft sleeve 3, leaving the retaining ribs 411 to be respectively meshed with the retaining grooves 321, and leaving the extension 332 inserted inside the door 44 formed between the flap 7 and the lower surface of the lug 4 As soon as the extension 332 is inserted inside the door 44, the lug 45 which forms an integral part of the lower surface of the lug 4 is placed in the through hole 332 so as to firmly maintain the extension 332 As soon as the tenon 45 is put in the through hole 332, the flap 7 rotates to the upper limit position, and the end extending towards the front 71 of the flap 7 East

  immediately driven so as to press the extension

  sion 331 in order to let the extension 331 be firmly held by the lug 4 Thanks to an axial arrangement with double locking (the holding ribs 411 with the holding grooves 321, and the lug 45 with the through hole 332), the wheel 1 is connected more stably and more firmly to the frame of the trolley

associated golf.
