The present invention relates, in general terms, to an improved apparatus for use in the sealing/resealing and subsequent re-inflation of a damaged inflatable article, as for example a punctured or flat tire (tyre) for a vehicle. The invention relates more particularly, but not exclusively, to an improved apparatus in the form of a kit which includes as principal components a supply/container of a fluid which is capable of resealing/repairing such a damaged tire to allow for subsequent re-inflation thereof, and a means for injection of such fluid into the damaged tire as well as for injection of air to allow for re-inflation thereof.
Wheeled vehicles of any given type are subject to puncturing of one or more wheels. Once a puncture occurs, the pressure within the tire (tyre) will decrease, either drastically or progressively dependent upon the nature and location of the puncture such that, within a finite period, the relevant tire is no longer suitable for use and is not capable of properly supporting the relevant vehicle.
When such a situation arises it becomes necessary for the damaged/deflated tire to be either repaired on the spot, to allow for subsequent re-inflation and re-use, or in the alternative to be actually removed from the vehicle and replaced by what is commonly referred to as the spare tire, to allow for repair of the damaged tire at a later date.
Regardless of which of these two alternatives is followed, the object is to restore the vehicle to a usable condition in the shortest possible time and with the least possible effort.
In recent years there have been a number of attempts made at providing an apparatus of this general type. One of these is disclosed in the present Applicant's U.S. Pat. No. 8,640,744. The present invention seeks to provide an improvement over the apparatus of that United States patent by providing an apparatus, in kit form, which is compact and hence able to be readily stored when not in use, yet is extremely simple to operate, with little physical effort required on the part of the operator. As such, an apparatus in accordance with the present invention lends itself to ready use, regardless of the age, sex and/or physical capabilities of the proposed user.
It is a preferred object of the present invention to provide an apparatus for the sealing/resealing and subsequent re-inflation of a damaged and/or deflated inflatable article, in particular a punctured and/or flat tire, which substantially overcomes, if not removes altogether the problems and disadvantages associated with the prior art and/or provides a useful commercial alternative.
The invention provides a simple method of, and apparatus for, sealing or repairing, and then re-inflating, a punctured tire. The apparatus in accordance with the present invention, in the form of a kit, is intended to overcome drawbacks and disadvantages associated with existing methods and apparatus. The kit in accordance with the present invention is compact (which lends itself to easy storage when not in use), fully reusable and extremely simple and effective to operate.
In accordance with one aspect of the present invention, but not necessarily the broadest aspect, there is provided an apparatus for the repairing and/or inflating of a damaged and/or deflated inflatable article, such as a punctured and/or flat tire, said apparatus including:
The arrangement is such that, when the container for said sealant composition is in its first, storage position or configuration, then actuation of the compressor will only allow for air to be dispensed from the valve assembly. On the other hand, when that same container is pivoted to its second, in some instances upright dispensing position, activation of the compressor will result in dispensing of sealant composition and air, to be injected into the tire or the like inflatable article.
Suitably, said container includes a main body portion which is closed at one end and has a neck portion extending substantially normally from the other, open end thereof, said neck portion of said container being adapted, in use, to receive and releasably retain said valve assembly.
Suitably, said valve assembly is releasably disposed within said neck portion of said container and is adapted to be in flow connection with said compressor assembly.
Suitably, said compressor assembly has associated therewith means allowing for connection to a source of power, said connection means being in the form of a retractable cord or power conduit, said cord or conduit having, at one end thereof, adaptor means allowing for connection to a source of electrical energy/power.
Suitably, said valve assembly has associated therewith a connector assembly including a pivoting or hinging member having a first hollow tube and a second hollow tube associated therewith and extending transversely of a closed end of said connector assembly.
Suitably, the apparatus includes a pair of nipples extending laterally from opposed sides of respective dividers of a case for housing said apparatus, a first of said pair of nipples allowing for releasable connection to said compressor assembly and a second of said pair of nipples allowing for releasable connection to a hose, in turn to be releasably connected to said inflatable article.
Preferably, actuation of said compressor when said container is in said first position/configuration allows air flow through the first hollow tube for inflation or re-inflation of said inflatable article.
Preferably, actuation of said compressor when said container is in said second position/configuration allows air flow through said second hollow tube for dispensing a mixture of air and sealant composition from said container to said inflatable article.
In some embodiments, a connector assembly associated with said valve assembly includes a main body adapted to be releasably connected to said neck portion of said container.
Suitably, said main body of said connector assembly includes a first passageway extending axially thereof, said first passageway terminating, at one end, with means allowing for releasable connection to said compressor assembly.
Suitably, said connector assembly includes a second passageway, in use to be in flow connection with a lateral substantially tubular extension of said main body of said connector assembly, wherein said lateral extension includes means allowing for releasable connection to a hose, in turn to be releasably connected to said inflatable article.
Further aspects and/or features of the present invention will become apparent from the following description.
In order that the invention may be more clearly understood and put into practical effect reference will now be made to a preferred embodiment of an apparatus in accordance with the present invention. The ensuing description is given by way of non-limitative example only and is with reference to the accompanying drawings wherein:
As shown in the drawings the present invention provides, in a compact manner and stored within a case generally designated 1, the apparatus needed to prepare and reseal a damaged or deflated inflatable article, that is for example a vehicle tire (tyre). To be located or held within the case 1, in a compact and readily accessible manner, are the principal components of the kit or apparatus, namely a container 100 for receiving and releasably retaining, for dispensation as and when necessary, a supply of a sealant composition of any suitable type, said container 100 having associated therewith a valve assembly 200, a compressor 300, an adaptor 400 intended, in use, to be inserted into the cigarette lighter outlet or an equivalent power outlet of the vehicle, such being an electrical connection with the compressor 300, a hose 500 to be, in use, connected to the tire valve, and a connector assembly 600 to which the container 100 and associated valve assembly 200 are to be connected. In this embodiment, all these components, to be described in more detail hereinafter, are housed within compartments of the case 1 formed by appropriately-shaped dividers, which may be either formed integrally with the case or, in the alternative, adapted in use to be removably and selectively located therein.
In accordance with the invention the container 100 for sealant composition is to be, preferably, in threaded connection with the connector assembly 600. The arrangement, put simply, is that when the container 100 is lying flat (see for example
As best shown in
The container 100 for sealing fluid may be constructed from any suitable material, and more preferably from a plastics material, and may be of any suitable shape. In the preferred embodiment illustrated such container 100 is in the form of a substantially cylindrical bottle having a main body portion 101 and a neck portion 102 extending from one end thereof and substantially normally thereto, with that neck portion 102 preferably including a plurality of external threads 103 extending along at least part of the axial dimension thereof. The container 100 is intended to house, for dispensing as and when required, a sealant or repair fluid of the type described and defined in, for example the present Applicant's International (PCT) Application No. PCT/AU2008/001499 or PCT/AU2007/001222, or Australian Patent No. 2009905952. It should be understood however, that neither the material of construction of the container 100, nor the actual composition of the repair/sealant composition to be housed therein, constitute part of the present invention.
When not in use, and in its storage position, the container 100 will lie flat in the case 1, located between dividers 4 and 5 and in the second or middle compartment 7, as shown for example in
Turning now to the compressor assembly 300, such is preferably in the form of a shaped container 301 which serves as a housing for a compressor and associated equipment. Preferably the container 301 includes a main body section, of a substantially cylindrical shape. The container 301 includes, housed there within, a compressor, motor or the like for operation thereof, and means allowing for connection of said compressor, motor or the like to a suitable power source. In the especially preferred embodiment illustrated such will take the form of a cord or electrical conduit 302, with the cord 302 having associated therewith at the free or external end thereof an adaptor or connector 400, of any known type, which in use can be releasably connectable to a cigarette lighter outlet or the equivalent power outlet of the vehicle, whereby to allow for activation/operation of the motor, and hence the compressor, as and when required.
The arrangement may include means allowing for retraction of the conduit 302 when not in use. The means for extraction/retraction of the cord 302 are not of the essence of the invention.
The second or middle compartment 7 of the bottom section 3 of case 1 includes, at one end thereof, a portion of lesser width which is adapted, in use, to have releasably located therein the connector assembly 600. The connector assembly 600 includes, as principal components, a substantially cylindrical member 601, open at one end and closed at the other, such being releasably affixable to a pivoting or hinging member 602 having a pair of hollow tubes including first hollow tube 603 and second hollow tube 604 associated therewith and extending transversely of the closed end thereof. The first hollow tube 603 does not provide fluid communication with the valve assembly 200 whereas the second hollow tube 604 allows fluid communication with the valve assembly 200. As shown for example in
As shown in, for example,
The main body 201 includes a shaped indent adapted to receive, and releasably retain, suitable sealing means, as for example O-ring type seal 205.
The main body 201 further includes, sited substantially centrally thereof and extending axially thereof, a hollow member 206 in flow connection with the passage 204. The hollow member 206 is sealed at the uppermost end thereof by, suitable sealing means, as for example, an O-ring type seal 207.
When the compressor 300 is actuated, air commences to flow via suitable hosing, and then through the nipple 605. If the container 100 is in the horizontal or storage position, as in
When the container 100, however, has pivoted to its upright position, see for example
In similar manner to the earlier described embodiment, in the embodiment of
Located at the top end of the passageway 703 is yet another O-ring seal 711, adapted to constitute a seal for said passageway 703. The compressor 300 housed within case 1 is in flow connection with the passageway 703. In use the lateral extension or outlet 710 is in flow connection with the damaged or flat tire.
When the compressor 300 is actuated, air commences to flow into the passageway 703. As pressure builds, the O-ring seal 711 will be moved from its seating, allowing air to flow via the passageway 711 into the container 100, to be mixed with the content thereof. As the compressor 300 continues to operate, the O-ring seal 708 will be forced relatively downwardly, in the direction of the arrow as shown, to allow the mixture of air and sealant composition to flow into the passageway 709, and from there via the outlet 710 and associated hose or tubing 500 to the tyre. Operation of the compressor 300 will be continued until such time as, firstly, the content of the container 100 has been dispensed/injected into the tire, and will continue until such time as the tire is re-inflated to the desired pressure (determined by reference to the pressure gauge 9).
An apparatus in accordance with the invention gives rise to a number of practical advantages when compared with known and in-use requirements.
Firstly, by being in a kit form, with all necessary relevant/components preferably provided interconnected, actual use or preparation for use is extremely simplified. Indeed all the user need do is:
Furthermore, the apparatus lends itself to ready re-use. Once a container 100 is emptied, it can be readily released, as by un-screwing, from the connector assembly 600, to be readily removed from the case 1 and replaced by a new, filled container.
In accordance with an especially preferred embodiment the apparatus may include a means, as for example an electrical micro-contact switch of any suitable type (not shown), which serves to allow the compressor 300 to function, and thereby allow for discharge of sealant composition from the container 100, only where the container 100 for sealant composition is connected to the connector assembly 600, has been rotated to the second positon/configuration, such as the vertical position as shown in, for example
This will remove the possibility of accidental or inadvertent discharge of sealant composition, which could otherwise take place when, for example, the compressor 300 is plugged in or in an electrical connection and/or in the instance of the connection on/off switch for the compressor 300 inadvertently or accidentally being moved permanently to the on position.
In some arrangements, when air only is required, as for example when the compressor is being used to re-inflate a tire, the hinged lid or top section 2 of the case 1 will activate the same micro-switch.
The apparatus in accordance with the invention preferably should include such a micro-switch, in the form of a “fail-safe” mechanism, to avoid the possibility of inadvertent discharge of sealant composition in the event that the air hose has not been connected at all, or not properly connected at least, to the tire valve before the compressor has been turned on. If such was to occur, the result would be that the container of sealant composition would be at best partially, and at worst fully, discharged by the time the user has realised the problem. Apart from the mess involved—which would need to be cleaned up—there would then be little, if any, sealant composition left to be used for sealing a deflated or damaged tire.
In an alternative arrangement, which is not shown in the drawings, the valve assembly could include, rather than the system of O-ring seals as previously described, a low cost seal of a known type, referenced to in this specification indirectly as aluminium induction seals. In such embodiments, as the container 100 is screwed into place relative to the valve/connector assembly, such an aluminium induction seal may be cut or screwed, or penetrated, by a small blade-like protrusion which could be formed as an integral part of the main body, thereby to overcome the sealing effect and allow for entry of air (generated by the compressor 300) into the container 100, to be mixed with the sealant composition for ultimate egress therefrom, via the nipple, into the hose 500 for delivery to the tire valve and tire.
In other alternative arrangements, such as the embodiments shown in
In some preferred arrangements, a second portion 2b of the top section 2 is configured to not hinge open. In such arrangements, second portion 2b is attached to the bottom section 3 via one or more fasteners, such as clips or buckles, e.g. made of suitable plastics material. Configuring the second portion 2b of the top section 2 to not hinge open prevents users accessing the compressor 300 in normal use.
Examples of suitable hinges 12 for hingedly attaching one or more top sections 2a, 2b of the case to the bottom section 3 of the case of the apparatus are shown in
In such alternative arrangements, the first portion 2a of the top section 2 can comprise an aperture 14 through which the container 100 can be viewed whilst the first portion 2a of the top section 2 is still closed. It is therefore possible to view at a glance that the container 100 is present in the case 1. Where the container 100 is formed of a transparent material, it is also possible to view at a glance that the container 100 comprises a sufficient quantity of the sealant composition. The aperture 14 is preferably an elongate aperture aligned with a longitudinal axis of the container 100 such that a substantial middle to upper portion of the length of the container 100 can be viewed there through.
In such alternative arrangements, a second portion 2b of the top section 2 can comprise an aperture, such as a circular aperture 16, through which the pressure gauge 9 can be viewed whilst the second portion 2b of the top section 2 is still closed.
In such alternative arrangements, the second portion 2b of the top section 2 can comprise a cavity or recess 18 for receiving therein the adaptor 400 such that the apparatus can be easily and quickly connected to a power outlet without the need to retrieve the adaptor from inside the case 1. A side of the case 1 can comprise a cavity or recess 20 for storing the power cord or conduit coupled to the adaptor 400.
In such alternative arrangements, the second portion 2b of the top section 2 can comprise a cavity or recess 22 for accommodating the on/off switch 19 for the compressor 300. The recessed on/off switch 19 prevents the on/off switch from protruding from the case 1 thus minimising the likelihood of inadvertent activation. In this arrangement, the compressor 300 can be activated via the switch 19 without the need to open the case 1, for example, when the inflatable article needs to be inflated or re-inflated, but not repaired.
