BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to accessories for vehicle tires, and particularly to a tool for removing a tire valve stem cap that aids in the removal and replacement of tire valve stem caps from dual-tire wheel assemblies.
2. Description of the Related Art
Dual-tire wheels are commonly found on trucks and other heavy vehicles. The tire air valves are typically found on the innermost tire (as shown in FIG. 1), which makes removal or replacement of the valve cap extremely difficult for most users. Attempting to reach the valve cap through the outer tire rim can result in staining of the user's clothing from accumulated dirt, tar, etc., or may even result in injury to the user through abrasions with the metal rim. Thus, a tool for removing a tire valve stem cap solving the aforementioned problems is desired.
SUMMARY OF THE INVENTION
The tool for removing a tire valve stem cap is an elongated tool, allowing a user to easily reach the valve stem on dual tires. The tool includes an elongated handle portion having opposed front and rear ends, and a head portion joined to the front end of the handle portion.
Preferably, the elongated handle portion has a substantially cylindrical contour and the head portion has a substantially circular cross-sectional contour. In some embodiments, the head portion has a larger diameter than the elongated handle portion, the head portion having a flared or substantially bell-shaped contour.
The head portion has a recess centrally formed in a front face thereof for receiving an annular gripping member. The annular gripping member has a central bore formed therethrough, with the central bore being dimensioned and configured for frictionally engaging the tire valve stem cap for removal and insertion thereof. The annular gripping member may be formed from rubber, plastic or the like, allowing for frictional engagement with the tire valve stem cap.
These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention is directed towards a tool for removing a tire valve stem cap. As best shown in FIG. 1, the tool 10 is an elongated tool, allowing a user to easily reach a valve stem cap 101 of a tire valve stem 100. Tool 10 is particularly useful in removing and replacing a valve stem cap 101 on dual tires, such as exemplary tire assembly T, although it should be understood that tool 10 may be used in combination with any suitable tire or wheel assembly.
As shown in FIG. 2, tool 10 includes an elongated handle portion 12 having opposed front and rear ends, and a head portion 14 joined to the front end of the handle portion 12. Preferably, the elongated handle portion 12 has a substantially cylindrical contour, and the head portion 14 is substantially circular in cross section (best shown in FIG. 4). In the preferred embodiment, the head portion 14 has a larger diameter than the elongated handle portion 12, with the head portion 14 having a flared or substantially bell-shaped contour.
In the some embodiments, elongated handle portion 12 and head portion 14 are formed from aluminum, although it should be understood that tool 10 may be formed from any suitable, structurally strong material. Further, in the some embodiments, tool 10 is approximately eighteen inches long, elongated handle portion 12 is approximately ⅝ of an inch in diameter, and head portion 14 has an outer diameter of approximately three-quarters of an inch.
The head portion 14 has a recess or opening 16 centrally formed in a front face thereof for receiving an annular gripping member 18 therein. The annular gripping member 18 has a central bore 20 formed therethrough, with the central bore 20 being dimensioned and configured for frictionally engaging and releasably retaining the tire valve stem cap 101 for selective removal and insertion thereof. The annular gripping member 18 may be formed from rubber, plastic or other resilient material, allowing for releasable frictional engagement with the tire valve stem cap 101.
In FIGS. 3 and 4, the annular gripping member 18 is shown as having a substantially annular cross-sectional contour, with both the inner and outer perimeters being circular in appearance. It should be understood that the inner surface of annular gripping member 18 may be contoured to increase frictional engagement with tire valve stem cap 101 through the addition of knurling or the like. Annular gripping member 18 may be secured within head portion 14 through the use of glue or any other suitable adhesive or other fastening means.
As shown in FIGS. 1 and 2, the outer surface of handle portion 12 may include knurling 22 or other surface configuration or additional gripping elements in order to increase the frictional coefficient thereof. Knurling 22 allows the user to retain a stable grip on handle portion 12. Further, although shown as having a static head 14 fixed to static handle portion 12, it should be understood that head 14 may be a ratcheting head, or a similar tool having a rotating head, or portion of the head, with respect to the handle.
In the alternative embodiment of FIGS. 5 and 6, tool 110 includes an elongated handle 112 and a head portion 114, mounted thereon, similar to that described above with reference to FIGS. 1-4. Head portion 114 has a recess or opening 116 centrally formed in a front face thereof for receiving a gripping member 118 therein. Annular gripping member 18 of FIGS. 1-4 had a substantially cylindrical bore, but the gripping member 118 has a central bore 120 formed therethrough that tapers, with a decreasing diameter along the direction from the open end of head 114 towards the handle 112 (for engaging the rounded valve stem cap 101 of valve stem 100). The central bore 120 is dimensioned and configured for frictionally engaging and releasably retaining the tire valve stem cap 101 for selective removal and insertion thereof. Similar to annular gripping member 18, gripping member 118 may be formed from rubber, plastic or other resilient, allowing for releasable frictional engagement with the tire valve stem cap 101. Preferably, a rim or annular lip 130 is formed about the open end of gripping member 118, as shown, for secure grasping by the user or a tool holder, during use, transport or storage and to ensure proper seating of the gripping member in head 114.
It is to be understood that the present invention is not limited to the embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
