The present invention relates generally to portable caddies, article holders and the like. More particularly, the present invention is a portable tire-handling device for holding and manipulating a vehicle tire while changing a flat tire or for other purposes.
Tires are likely the single most frequent repair or replacement item on a motor vehicle. The carriage of a spare tire is nearly universal in motor vehicles, with the exception being vehicles equipped with newer “run-flat” type tires. No other repair or replacement item or part is nearly so likely to be carried in a motor vehicle as a spare tire.
Motor vehicle tires have become considerably more reliable over the years, but total reliability is yet to be achieved. At the same time, motor vehicles have generally become heavier, with their wheels and tires becoming correspondingly larger and heavier as well. In past generations, the fifteen-inch wheel and a relatively narrow tire was the norm for full-size vehicles, but wheel and tire sizes have been increasing to ever larger diameters and widths, with corresponding weight increases, as the years have progressed.
In the past, it was considered routine to remove a flat tire and replace it with a spare tire carried in the vehicle. Even relatively small people could handle a standard tire, albeit with some degree of effort and exertion. With ever larger tires and wheels, many drivers (both male and female) find themselves unable to handle the weight and bulk of a tire from their vehicle when a roadside tire change is required, particularly in the case of larger sport-utility vehicles with wheels ranging perhaps up to nineteen inches in diameter. Yet, very little has been done in the past to aid the driver in this task.
Thus, a tire-handling device solving the aforementioned problems is desired.
The tire-handling device comprises a relatively compact and lightweight tool, which may be carried easily in the trunk or storage area of a motor vehicle to facilitate handling of a tire during the removal and replacement thereof when changing a flat tire or similar vehicle service. The tire handler includes a low, flat floor with four peripheral walls defining a tire support area therebetween. Two of the opposed walls include arcuate cutouts to provide clearance for a tire resting upon the device.
A vertically adjustable tire support cradle spans substantially all of the area of the underlying floor of the device. The tire support cradle is supported at opposite ends by a vertically adjustable handle. The handles may be locked in position to place the cradle at the desired height for positioning the device beneath a tire on a raised axle, or for positioning a spare or repaired tire at the proper height for securing to the wheel hub during a tire change. The cradle includes a pair of opposed tire support belt rollers and a belt extending therebetween. The belt enables a user of the device to rotate the tire as required to align the wheel mounting stud holes with their mounting studs, with the roller and belt assembly providing sufficient friction to hold the wheel and tire in position.
Various accessories may be provided for the tire-handling device, including a wheeled platform for greater versatility. The wheeled platform may include a vertically adjustable stop or brake to preclude unwanted motion of the assembly. A ramp may also be provided, the ramp being removably attachable to either handle to enable the user to transfer the tire between the device and the adjacent surface. The ramp may be removably attached to the remainder of the structure of the device. Lighting may also be provided along the upper periphery of the device for use at night or in conditions of poor light.
These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.
Similar reference characters denote corresponding features consistently throughout the attached drawings.
The present invention is a relatively small and lightweight tire-handling device 10 suitable for carriage within the trunk or storage area of a motor vehicle, trailer, or the like to facilitate roadside changing of a tire or for other occasions when handling a tire may be necessary. The device 10 is configured for placement beneath an elevated tire on a motor vehicle V or the like to support and maneuver the tire during the removal thereof from the vehicle, and for the support and maneuvering of a spare tire (or repaired tire, etc.) back into position for installation on the vehicle.
Mutually opposed first and second handle assemblies extend upwardly from the corresponding first and second ends 14 a, 14 b of the floor 12. These handle assemblies are vertically adjustable, and permit the vertical adjustment of the tire support structure to compensate for the elevation of a lifted tire during tire change operations or the like.
Each of the handle assemblies includes a generally vertically disposed base tube 24 attached to and extending upwardly from the respective end 14 a, 14 b of the floor 12. A tire cradle attachment tube 26 telescopes concentrically within each of the base tubes 24, to extend from and retract into the respective base tube as desired. A tire support cradle attachment arm 28 extends inwardly, i.e., toward its opposite member, from the upper end of each tire cradle attachment tube 26, with the two arms 28 supporting a rigid, arcuate tire support cradle 30 therebetween. The tire support cradle 30 is generally curved to correspond to the rounded circumference of a tire T, which may be supported and carried thereon. A generally horizontally disposed handgrip 32 extends outwardly from the upper end of each tire cradle attachment tube 26, i.e., opposite the tire support cradle attachment arms. The handgrips 32 may include a padded grip cover thereon, if so desired.
Each handgrip 32 includes a latch release lever 34 pivotally extending from its base end. The lever 34 is connected to a pair of latch pins 36 by cables 38. The pins 36 are biased outwardly by springs 40 to engage holes or passages 42 formed through the walls of the base tube 24 and its tire cradle support or attachment tube 26. When it is desired to adjust the height of the tire support cradle 30, the latch release levers 34 of the two handle mechanisms are drawn toward their respective handgrips 32, thereby withdrawing the pins 36 from their passages 42 and allowing the tire cradle support tubes 26 to be adjusted upwardly or downwardly within their respective base tubes 24. The levers 34 are released when the cradle 30 has been positioned at about the height desired, with the pins 36 being urged into the holes or passages 42 through the two tubes 24 and 26 as the holes become aligned with one another during adjustment. This mechanism allows the height of the tire support cradle 30 to be adjusted closely to the height of the bottom of the tire T, to support the tire T as it is removed from the wheel hub. The tire support cradle 30 height may also be adjusted to vertically align a tire T placed thereon with the wheel hub for installation of the tire thereon, thereby obviating any need to physically lift the tire T into position.
Details of the tire support cradle 30 are shown in
The tire-handling device 10 may be used as described above, i.e., with its floor 12 resting directly upon the underlying surface, or may alternatively be supported by wheels, either permanently attached to the floor 12, or, more preferably, with the wheels depending from a removable platform.
It will be recognized that it will be necessary to remove a tire T from its rest position atop the tire-handling device 10 and to reposition a tire T thereon during the use of the device. Accordingly, a ramp 58 may be provided to facilitate the placement or removal of a tire T upon or from the device, as shown in
It is likely that there will be occasion to use the present tire-handling device 10 at night, or at least in conditions of low light. Accordingly, one embodiment may include lighting therein, as shown in
In conclusion, the tire-handling device 10 in its various embodiments will prove to be a most appreciated accessory for many motorists. The device may be stored in the trunk or storage compartment of a car or other motor vehicle until needed, and removed and positioned as desired for the tire change operation. The device may include a pair of flexible carrying handles 78 to facilitate the carriage and positioning of the device. When the vehicle has been jacked up to elevate the tire above the underlying surface, the tire cradle 30 of the tire-handling device 10 is adjusted vertically to position the cradle 30 as closely as possible beneath the raised tire. This allows the tire to be unbolted from the wheel hub and to rest upon the tire support cradle 30 with minimal physical effort by the user of the device. The tire-handling device 10 with the defective tire resting thereon may be maneuvered as desired by means of the wheeled support platform and the defective tire and wheel assembly may be rolled from the handling device for storage as desired. The ramp provided with the tire-handling device will be of assistance in maneuvering the defective tire and wheel assembly into the trunk or storage compartment of the vehicle, if sufficient length is provided for the ramp.
Once the defective tire and wheel assembly have been removed, the inflated spare or replacement tire and wheel assembly may be installed. The procedure is essentially the reverse of that described above, i.e., height of the tire support cradle is adjusted as required, the new wheel and tire are rolled onto the device by means of the ramp, and the tire-handling device with its fresh tire and wheel assembly are rolled into position at the wheel hub. The tire and wheel assembly may be rotated upon the support cradle by means of the roller and belt assembly to align the mounting lug holes of the wheel with the mounting lugs of the wheel hub. The new tire and the wheel assembly are bolted in place, and the tire-handling device 10 is stored away for future use.
Accordingly, the tire-handling device 10 will prove to be a most desirable accessory for many motorists, particularly persons who may have less than ideal upper body strength for lifting and manipulating a wheel and tire assembly. Even stronger men will appreciate the value of the tire-handling device 10 when presented with the need to handle a larger wheel-and-tire assembly from a larger sport utility vehicle, light truck, or the like. Thus, many motorists will appreciate the presence of the tire-handling device 10 onboard their vehicles as they travel.
It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
