The present disclosure generally relates tubeless tires. More particularly but not exclusively the present disclosure relates to an apparatus and method for seating a tubeless tire.
Unlike pneumatic tires which use a separate inner tube, tubeless tires have continuous ribs molded integrally into the bead of the tire so that they are forced by the pressure of the air inside the tire to seal with the flanges of the metal rim of the wheel. The tire bead is the term for the edge of a tire that sits on the wheel. The bead is an important component of tire construction, helping it to stand and support weight. The rim has a slot or groove defining the flanges. When the tire is properly inflated the air pressure within the tire keeps the bead in this groove. The tire bead is held in this groove by air pressure. This is referred to as seating the tire, the tire is properly positioned on the rim with the bead of the tire snuggly engaging the flanges of the rim by of air pressure.
Inflating and seating tubeless tires is a burdensome process that poses several dangers. The tire is mounted on the rim and laid flat on the floor, sometimes a small support is used to space the rim and tire slight from the floor (e.g. a couple of side by side two-by-fours on a plank). The user will then inflate the tire about the rim. At a given air pressure level, the user will use a bead seater tool which includes a tank and nozzle to blast air pressure between at the junction of the tire bead with the rim flange there seating the bead within the groove so that it properly engages the inner side of the flange. The user will continue to add air pressure. The user may stop adding pressure to place the tire vertically to add the remaining air pressure. The foregoing steps are time consuming and may cause injury to the worker as the tire needs to be rolled, laid flat. The worker needs to bend down to connect the air tube to the tire. The worker also needs to bend down near the inflating tire during blasting with the heavy bead seater tool. The worker needs to lift the tire vertically and position it for additional inflation, thereby needing to remove the air tube in order to add another air tube and finally the tire is rolled out to be mounted to the object vehicle. The foregoing steps can cause fatigue as the worker is freely handling high-pressure tools such as the bead seater. Improper seating may also be life threatening as the blast may backfire. Overinflating the tire can also cause the tire to explode thereby potentially gravely injuring the worker. In some cases, the user should stop inflating the tire and the blast the rim and tire junction for seating with the bead seating tool and then restart inflating as blasting during inflating may also cause blowback which can be dangerous.

With reference to
The apparatus 10 comprises an enclosure 14 including a platform 16 having spaced apart cage bars 18 upstanding therefrom along the lateral sides 20A and 20B of the enclosure 14 and defining front and rear faces 22A and 22B respectively. As shown both front and rear faces, 22A and 22B are open and define a respective entry opening for the tire 12 and rim 13 assembly. It is to be understood that the terms ‘front’ and ‘rear’ are interchangeable and are only used herein for indicative purposes. In an embodiment, only one of the faces 22A and 22B may be open. In an embodiment, closure doors (not shown) may also be used to selectively close and open either one of the faces 22A and 22B.
The configuration of the enclosure 14 provides lateral access opening 24 at each lateral side 20A and 20B. In this example, the lateral openings 24 are formed by the spaces between the cage bars 18. The bars 18 define the top part 26 of the enclosure 14. In this example, bars 18 on side 20A are co-aligned bars 18 on side 20B and meet up (at top part 26) by curved extension portions 28 defining the dome like configuration of the top part 26. A flat member 29 sits on top of the extension portions 28 to provide structural support to the cage 14 and maintain the bars 18 in place along with platform 16.
As such, enclosure 14 is a cage with flat platform 16, bars 18 on each lateral side 20A and 20B meeting at the top part 26 via curved extension 28 and open front and rear faces 22A and 22B. The enclosure cage 14 thus defines the tire receiving area 30 therein.
The platform 16 includes a tire roller 32 for providing the tire 12 to roll into and out of the cage 14 so as to be positioned within the area 30 and removed therefrom. The tire roller includes a pair of longitudinal rollers 34A and 34B spanning the width of a tire rolling thereon and forming a groove 36 therebetween for keeping the tire 12 in place during inflating and seating as will be further described herein. Short ramps 35A, 35B are adjacent to rollers 34A and 34B for rolling a tire onto or off of a roller. The short ramps 35 and 35B are connected to at their ends to side support members 37 which also rollingly receive the ends of rollers 34A and 34B. Of course, other types of rollers to facilitate tire movement in and out of the cage 14 can be contemplated by the skilled artisan within the scope of the present disclosure.
The enclosure cage 14 includes a lateral tire support element 38 mounted to the bars 18 at lateral side 20B. The support element 38 is in the form of backing plate extending into area 30 with rear clamps 40 clamped to bars 18. The backing plate 38 includes an impact face 39 comprising a resilient and flexible material for not damaging the rim 13 of the tire 12 (see
A control unit 42 is mounted to lateral side 20A of the enclosure cage 14. The control unit 42 includes a panel 44 mounted to a bar 18 via a rear clamp 46A. The panel 44 includes an inlet 48 for being connected to an air pressure tank (not shown but known in the art). A conduit in the form of an air hose 50 extends from the panel 44 along the extension portion 28 of the bar 18 that the panel 44 is mounted to. From this position at the top 26 of the extension portion 28, the hose extends downwardly along a co-aligned bar 18 on side 20B (where it is attached thereto via an attachment 45 such as tie-wrap) towards the platform 16. The hose 50 includes an open air chuck 52 for being connected to the tire 12 during inflating thereof. As such, the chuck 52 is provided to be easily mounted to the tire for inflating as it is in a convenient position with enough free slack (from its attachment 45) to allow the user to conveniently secure it to the tire for inflation.
A conduit 54 extends from the panel 44 to a bead-seater 56 which will be discussed further below.
The panel 44 includes a user interface board 58 for allowing the user to selectively control air pressure flowing from the air pressure source tank (not shown) to the tire 12, via hose 50 during the inflating and to control air pressure flowing to the bead-seater 56 via hose 54 connected to a safety valve 55 (shown in
The panel 44 and the bead-seater 56 are both mounted to a support frame 60. Support frame 60 includes lateral wing members 62A and 62B, each wing member 62A and 62B including a respective rear clamp 46A and 46B for clamping a respective bar 18 on lateral side 20A of the enclosure cage 14. The panel 44 is mounted to lateral wing member 62A.
With reference to
Bead-seater 56 is mounted to the center portion 64 of the support frame 60 interposed between the wings 62A and 62B, which downwardly extend from the center portion 64. The bead-seater 56 includes a tank 66 connected to the conduit 54 which is connected to the control panel 44 for selectively receiving air pressure from the source tank (not shown but known in the art). The tank 66 provides for storing a sufficient amount of pressurized air which is blasted out via the nozzle 68 downwardly and radially extending from the tank 66 and connected thereto via tank inlet tube 80 and connector 82 (see
The user interface board 58 provides for the user to selectively blast air from the tank 66. The user interface board 58 is thus fixedly positioned neat the fixed but movable position of the bead seater 56 providing an ergonomic and safe arrangement for the user. The interface board 58 and the bead seater is thus laid out in front of the user near eye level range as shown in
A lever 70 radially extends from tank 66 allowing the user to pivot the tool 56 about the pivot defined by the center portion 64 and as shown by the arrows P in
The center portion 64 defines an inwardly rectangular body for receiving pivots 65 pivotally connected to a connector 67 extending from the tank of the bead seater 56 as shown in
With reference to
With reference to
As shown in
At a desired inflated level, the user will seat the bead of the tire on the rim via the bead-seater 56. For this operation, the user may selectively stop inflating the tire 12 via the control unit 42.
As shown in
Apparatus 10 allows the user to inflate the tire without laying it on the floor and having to pick it up again. The worker does not need to bend down to connect the air hose to the tire and the does not need to walk towards the source tank to shut it off in order to execute the seating step. The rim/tire assembly is always in the vertical position, eliminating the need to pick and drop the assembly on the ground. This also protects the rim from getting scratched.
During seating, the worker does not need to pick up the bead seating tool and bend down to blast air. The weight of the bead-seater and kick-back force when blasting is on the enclosure thereby reducing worker fatigue and risk of injury. The nozzle of the bead seater can be selectively adjusted in length and angle to account for tires and rims of variable diameters. The bead seater nozzle retracts automatically outside the protective enclosure cage, preventing it from being a projectile in the case of an explosion.
All operations are performed with the tire inside the protective enclosure cage thereby increasing safety. The rim/tire assembly is simply rolled in and out of the cage.
Tire inflating and tire seating operations are controlled via the same control unit which is on the cage next to the bead seater tool thereby providing the worker with easier handling. The worker simply stands at face 20A for the inflating and seating operations. Moreover, the air inlet from the source tank is the same for both tire seating and inflating operations.
The pivotable bead seater tool and control assembly with conduit for inflating a tire and backing plate can be installed on different cage models and can be retro-fitted on approved pre-purchased cages.
The apparatus 10 and components thereof can be provided in kits.
