Description
(1) TITLE OF THE INVENTION
VEHICLE WHEEL REPLACING EQUIPMENT
(2) BACKGROUND TO THE INVENTION
In especially the case of the wheels of large vehicles the replacement of a flat tyre by the spare wheel often involves a cumbersome effort owing to the sheer weight of such wheels. It is ,in fact, a job that cannot easily be dealt with by one person only as the action of replacement involves the removal of the flat tyre that is in an upright condition from its position of use, the retraction of the spare wheel from below the body of the vehicle and its location in the use condition with the flat tyre finally being stored in the spare wheel cradle. It is, amongst others, an object of this invention to facilitate such actions.
(3) FIELD OF THE INVENTION
This invention relates to wheel manipulating equipment for use in manipulating vehicle wheels in response to their circumferential gripping from one side. While not so limited the invention finds useful application when in the form of wheel replacing equipment for replacing a flat tyre with a spare wheel.
(4) PRIOR ART DESCRIPTION
The nearest prior art equipment known to the applicant in removing a wheel that has gone flat once a vehicle to which such wheel is attached has been appropriately jacked includes an elevatable wheel gripping cradle that is used to circumferentially grip such wheel once the device has been displaced to the matching elevation. Once such wheel has been removed from the vehicle the cradle is lowered to a level in which it can be removed there from while still in its upright condition. A spare wheel that is stored up against the bottom of such vehicle must be removed in another way prior to its positioning in an upright condition to the cradle for elevation and fitment to the hub of the vehicle from which the wheel with the flat tyre has been removed.
(5) BRIEF DESCRIPTION OF THE DRAWING
The invention is now described, by way of example, with reference to the accompanying drawings. In the drawings
Figure 1 in side elevation shows vehicle wheel manipulating equipment in the form of manually manipulable vehicle wheel replacing equipment for use in manipulating and especially replacing flat tyres on vehicle with their spares wheels,
Figure 2 shows the wheel replacing equipment in plan view, Figure 3 shows the wheel replacing equipment in frontal view, and
Figure 4 diagrammatically shows the operation of the wheel replacing equipment in replacing a flat tyre.
(6) DETAILED DESCRIPTION OF THE DRAWINGS
Referring to figures 1 to 3 of the drawings vehicle wheel manipulating equipment in the form of manually manipulable vehicle wheel replacing equipment is generally indicated by reference numeral 10.
The equipment 10 comprises swivellably mounted holding means in the form of a grasping facility 12 constituted from a set of circumferentially arranged holding formations 14 extending from base providing means in the form of a set of regularly spaced base defining arms 16 that radiate from a common centre as provided by a central support 18 including a journal 18.1 by means of which the grasping facility 12 is swivellably and rotatably fitted to jacking means in the form of a hydraulic jack 20 for swivelling it between grasping facility upright and horizontal conditions while the jack 20 is used for lifting and lowering the grasping facility 12 in the process of performing a wheel relocation function. The jack 20 is in turn mounted on a mobile holding means carrier in the form of a trolley 22 by means of which the equipment 10 is rollably displaceable between its locations of use. The grasping facility 12 in combination with the jack 20 defines a jacking and swivelling assembly 24.
Each holding formation 14 is constituted from a holding arm 26 that is swivellably mounted to its base defining arm 16 while its free end is fitted with gripping means in the form of a gripping finger 28. The extent of swivelling the holding arms 26 relative to their base defining arms 16 is limited to between a folded condition in which they lie flush there against, as for example shown in figure 1(a), and an operative condition in which they extends transverse thereto, as shown in figure 1 (b). This is achieved by way of stops 30 into which holding arms 26 are swivellably mounted.
In again referring to figure 1(b) and in their extended conditions a holding or grasping zone 32 is defined intermediate the holding formations 14 and beyond the arms 16 into which a wheel is received along a grasping zone inlet 34 during use of the equipment 10. When the grasping facility 12 is in its grasping zone defining condition while holding a wheel the gripping fingers 28 extend into the grasping zone inlet 34 in each performing a tyre outer surface gripping function of the tyre of such wheel in becoming lodged into tyre treading thereby promoting a firm wheel gripping action. The cross sectional size of the grasping zone 32 is adjustable by way of telescopic adjustment of the arms 16 as locked at their desired lengths by means of locking wing nuts 36, as shown in figures 1 and 2(a). The grasping facility 12 is swivellably mounted to the end of the piston 38 of the jack 20 via the journal 18.1 by way of an extent of swivelling limiting bracket 40 (as more clearly shown in figure 1) that limits the range of swivelling of the grasping facility 12 to an angle of 90 degrees. Swivelling of the grasping facility 2 is constrained to between a condition in which the holding zone 32 and thus the arms 16 extend transverse to the axis 42 of the jack 20, as shown in figures 1(a), 2(a) and 3(a), for overhead wheel location and release, and a condition in which it extends generally parallel to the axis 42, as shown in figures 1 (b), 2(b) and 3(b) for vertical wheel location and release. When in its condition of being transverse to the axis 42 the grasping facility is 12 locked against swivelling by way of a locking catch 44, as shown in figure 1 that releasably engages the support 18 to the bracket 40. As shown more clearly in figure 2 the trolley 22 extends channel shaped in plan view by way of a cross member 46 and side members 50. The assembly 24 is in such a way mounted onto the cross member 46 to cause the swivelling action of the grasping facility 12 into its holding zone upright condition to proceed into a zone 48 that extends intermediate the side members 50. The trolley 22 is manipulable via its rollers 52 of which the trailing roller 52.1 is castor fashion mounted to the cross member 46 to promote trolley steering.
In an embodiment the manipulator 10 is disassemblable by removal of the grasping facility 12 from the jack 20 and by disengagement of the jack 20 from the trolley to enable the compact storage of the disassembled equipment.
In use and also referring to figure 4 replacement of the wheel 54 of which the tyre is flat is achieved by causing the grasping facility 12 to swivel to its grasping zone upright extending condition according to figure 1 (b), 2(b) and 3(b). The grasping facility 12 is subsequently
jacked to its flat tyre wheel alignment condition where the arms 16 are adjusted, if required, to cause the grasping zone 32 to match the diameter of the wheel 54 to ensure a firm gripping effect. The grasping facility 14 is preferably rotated, if required, to cause two of the holding arms 26 to automatically swivel outward under the force of gravity while the upper arm 26.1 is manually held in such condition. While not shown the grasping facility 12 may be fitted with releasable catches by means of which the arms 26 can locked in their outwardly extending conditions, such as shown in figure 1 (b). The manipulator 10 is then pushed in the direction of arrow 56 resulting in the wheel 54 entering the grasping zone 32 along the grasping zone inlet 34 until the inside of the wheel 52 lies against the base defining arms 16, as shown in figure 4(a). In the process of passing into the grasping zone 32 the fingers 28 run firmly along the tyre tread and generally against the tread direction. Proper gripping receipt of the wheel 54 into the zone 32 is achieved when a substantial part of the wheel 54 is situated within the grasping zone 32 while each of the fingers 28 form a gripping engagement with the tread of the tyre of the wheel 54. The wheel 54 is thus removed from its use condition once the wheel nuts have been removed by simple retraction of the trolley 22. The wheel 54 is subsequently removed from the grasping zone 32 by dislodging it and putting it aside. This can be achieved while the grasping facility 12 is still in its grasping zone vertically situated condition or after the grasping facility has been swivelled to its grasping zone horizontally extending condition in which it is held by the action of the catch 44. While held in or returned to its grasping zone horizontally extending condition the trolley 22 is located below and in alignment with the spare wheel 58 of the vehicle involved in the tyre replacement action. With the holding arms 26 in their grasping zone 32 defining conditions the grasping facility 12 is jacked into engagement with the spare wheel 58, as shown in figure 4(b), and the wheel 58 released from its cradle. It will be appreciated that the cross sectional area of the grasping zone 32 will have to be re-adjusted to accommodate for increased wheel diameter of the pressurised wheel 58. The grasping-facility 12, as holding the wheel 58, is thus lowered by releasing the jack 20. Thereafter the trolley 22 is pulled from underneath the vehicle.
As shown in figure 4(c) operative fitting of the wheel 58 is achieved by permitting the grasping facility 12 to swivel to its gasping zone upright condition on release of the locking catch 44, aligning the wheel 58 with the wheel-bolting layout on the wheel drum, pushing the wheel into engagement and bolting the wheel into its operative condition. The grasping
facility 12 is then released from the wheel by retracting the trolley 22 in the process perhaps releasing the wing nuts 36 to release the grip of the grasping facility 12 onto the wheel 58.
It desired to store the wheel 54 in the spare wheel cradle it is fitted to the grasping zone 32, as desirably adjusted. While the grasping facility 12 has been swivelled and locked in its grasping zone horizontally extending condition the wheel 54 is simply fitted to the cradle by way of a set of steps that are the reverse of that for removal of the spare wheel.
As shown in figure 4(d) the vehicle jack is naturally subsequently removed resulting in the vehicle being at the ready to be driven off.
The procedure is described with reference to a vehicle of which the spare wheel cradle is situated from below up against its body. This is naturally not necessarily the case. A spare wheel that is, for example, situated at a high elevation and in an upright condition, as often found on four-by-four vehicles, must be manually removed. Once on the ground it is simply passed into the grasping zone 32, whether extending upright or horizontally, where after the spare wheel is operatively fitted to the vehicle by way of the procedure as already described. The manipulator of the invention is particularly useful in replacing a flat tyre that is too large to be manually handled or only handlable with difficulty. But it can naturally also be used under other tyre replacement circumstances as well to facilitate such operation. It can even be used to move wheels between locations not necessarily involving vehicle wheel replacement.
