Description

TECHNICAL FIELD

The present disclosure relates to tire inflation repair assemblies and methods, and in particular embodiments, currency operated fluid addition and tire repair assemblies and methods.

BACKGROUND

Fluids that may be added to tires to repair leaks in tires are currently available. The present disclosure addresses the problem of providing these fluids at remote locations at a cost to the consumer, thereby alleviating the need for the consumer to store these fluids in a vehicle. The storage of these fluids can be difficult because the consumer is required to periodically exchange the fluids for other fluids that may be newer or fresher fluids. The present disclosure provides currency operated assemblies and methods for providing these fluids. The preparation of these assemblies and methods can be difficult for at least the reason that the fluids have a tendency to clog conduits that they may in for extended periods of time. Embodiments of the present disclosure provide methods and assemblies that overcome these problems.

DESCRIPTION

The assemblies and methods of the present disclosure will be described with reference to FIGS. 1-4. Referring first to FIG. 1, an assembly 10 is shown that includes an air consolidation assembly 12. Air consolidation assembly 12 can be a motorized compressor, for example. It can also be a pressurized tank of air. The air that may be utilized may be pure oxygen, or air itself which is a mixture of oxygen, nitrogen, and carbon dioxide, for example. It may also be nitrogen, for example. This air supply 12 may be coupled to a valve assembly 16. Valve assembly 16 may be a solenoid valve that can be operated through mechanical and/or electrical means, for example. In accordance with example configurations, a mechanically operated solenoid valve may provide air from assembly 12 to fluid storage assembly 14. Fluid storage assembly 14 may be a tank or other container that may be constructed of, for example, metal or an inert plastic such as a polypropylene or polystyrene material. Fluid container 14 can contain a tire sealant, for example. The fluid can be, for example, liquid latex based, liquid rubber based, synthetic foaming agents and of varying viscus coagulating properties to seal punctures. Control of value 16 thereby providing air from assembly 12 through liquid container 14 can be manipulated through a user interface. The user interface may be mechanical and/or electrical. The user interface may be computer operated, for example, as well. The user interface may be configured to receive coins for operation or other currency, such as dollar bills. The user interface may also be configured to receive credit cards for operation as well. Upon initiation of the valve solenoid, air can be provided from air storage assembly 12 to fluid container 14, and fluid and air can be provided to a tire for re-inflation and/or repair, as desired. The tubing connecting air assembly 12 and the fluid assembly 14 as well as the tubing to the tire can be constructed of an inert material that does not facilitate the solidification of the sealant material in tank 14. In accordance with example configurations, the sequence of events can be started to facilitate the repair and/or filling of a tire. For example, upon initiation of operation of assembly 10, a slight amount of air can be added to the tire, and then the solenoid engaged to provide tire sealant to the tire, and then a desired amount of tire sealant or a predetermined amount of tire sealant is added followed by air being provided through the lines to the tire. In such a fashion, the lines exiting the assembly can be cleared of sealant for the next use.

Referring to FIG. 2, an assembly 20 is provided according to another embodiment. In accordance with example configurations, assembly 20 includes air assembly 12 which, as shown here, is an air compressor. Assembly 20 can include valve assembly 16 as well as tank assembly 14. Assembly 20 can also include interface 22. As shown here, interface 22 can be a coin operated interface. Assembly 20 can include a top cover 30 as well as a door panel 32 that may be connected to a housing 28 that encompasses a substantial number of assemblies within assembly 20. Assembly 20 can also include line 24 such as a tire hose that may be utilized to extend to a tire 26 for inflation.

As can be seen from assembly 20, repair maintenance access can be provided to different components of assembly 20 by design. For example, cover 30 can be removed from assembly 20 to allow access to air assembly 12 for repair and maintenance. Also, door 32 can be coupled to housing 28 to allow for repair and maintenance and/or refilling of tank 14. According to example implementations, tank 14 can be a refillable tank that may not have hard side walls. It may be simply a bag with soft side walls that may be suspended in a tank. These tanks can have easy-clasp configurations or snap fits that allow for the quick release of the tank to the hardware of assembly 12. In accordance with example implementations, upon initiation of the repair and filling sequence, compressor 12 may be initiated for a few moments to build up sufficient pressure and air provided to tire 26, then at a predetermined time or desired time, valve 16 may be engaged to provide fluid from tank 14 through tubing 24 to tire 26. Upon a desired amount of time and/or an amount of fluid being provided to tire 26, a close down or cleaning sequence may be initiated, allowing for the removal of fluid from lines such as tire line 24.

Referring to FIG. 3, tire repair assembly 50 can include a tire sealant tank 51. Tank 51 can be configured as a product storage tank and may include a proprietary filling unit that only accepts manufacture/operator designed interfaces to discourage other non-approved sealants from being utilized. Tank 51 can contain a suspension of flakes and fine fibers in a liquid, and/or a natural or synthetic liquid rubber; example materials include latex materials.

Air assembly 52 such as a pressure unit that can include an air compressor such as diaphragm pump, piston or screw pump and/or air pressure pump, can be coupled to the tire sealant tank 51 via pressure unit product connection 59.
