BACKGROUND AND SUMMARY
This invention pertains generally to systems for attachment of a tire protection device to a tire and/or wheel. A tire protection device generally takes the form of a covering applied to the exterior surface of a tire and is used to prevent or mitigate damage to the tire used in vehicle operation. The types of damage that tires are typically subjected to include, but are not limited to, cuts from rough terrain, sabotage, fire, and ballistic attacks. Various methodologies to attach the device to the tire and/or wheel are described herein. The geometry/design of the tire protection device(s) referenced herein and the materials/construction of the tire protection device(s) referenced herein are covered in separate filings, including those set forth in U.S. Provisional Application 61/073,897 and any successor application thereto—the teachings of which are incorporated herein by reference.
Methodologies for sidewall and tread protection have been covered in numerous U.S. patents. Representative examples of these patents include: U.S. Pat. No. 235,251 for “Sidewall Protector,” issued Mar. 6, 1915; U.S. Pat. No. 1,867,518 for “Mud Guard,” issued Apr. 10, 1928; U.S. Pat. No. 1,905,674 for “Splash Protector,” issued Jan. 2, 1931; U.S. Pat. No. 2,017,891 for “Skip Preventer,” issued Aug. 11, 1933; U.S. Pat. No. 2,334,388 for “Ornamental Sidewall,” issued Nov. 12, 1941; U.S. Pat. No. 3,187,797 for “Water Deflecting Sidewall,” issued Nov. 27, 1963; U.S. Pat. No. 3,811,488 for “Tread & Sidewall Protector,” issued Apr. 3, 1989; U.S. Pat. No. 4,030,530 for “Removable Tread,” issued Sep. 26, 1991; U.S. Pat. No. 4,111,250 for “Removable Tread,” issued Nov. 19, 1986; U.S. Pat. No. 4,235,271 for “Sidewall Protector,” issued Jul. 13, 1979; and U.S. Pat. No. 4,319,618 for “Sidewall Protector,” issued Apr. 28, 1980.
However, while all of the aforesaid prior devices and methods exist to protect certain aspects of the tire, all have disadvantages. First, the protection device(s) described that are compressed between the wheel flange and the tire bead may cause excessive wear on the tire bead. Second, the protection device(s) described with excessive or inaccessible hardware cannot be easily assembled or disassembled from the wheel/tire assembly. Third, in many cases, the protection device(s) described must be removed in order for the tire to be replaced.
The instant invention resolves and avoids these difficulties using novel attachment methodologies, resulting in numerous advantages. First, these methods for attachment of a protection device to a wheel/tire assembly are more versatile and robust. Second, these attachment methods for a protection device are simplified and require less time to assemble and disassemble. Third, these attachment methods for a protection device are simplified and require fewer parts to affix the device to the wheel/tire assembly. Fourth, these attachment methods can be used on any type of road wheel including, but not limited to, single and multi-piece wheels. Fifth, the mode of attachment for the protection device can include isolation methods that can prevent or mitigate damage to the wheel/tire assembly from impact or other dynamic shocks experienced during vehicle operation. Sixth, these attachment methods allow for lateral and radial tire and/or wheel flexing at various operating pressures. The numerous other advantages of our invention will become more apparent in view of the more detailed description and claims that follow.

DESCRIPTION
FIG. 2 illustrates the protection device 1 affixed directly to the tire 2 by means of spray on coatings or adhesives 3 that apply directly to the tire and/or wheel. (Although steel wheels are shown in many of the drawing figures, it is clear that many of these concepts can be extended to wheels constructed of any material or combinations of material. Also, most of the concepts described can be applied to one-piece or multi-piece rims).
FIG. 3 illustrates the protection device 1 attached directly to the rim 4 using a threaded interface 5. The protection device 1 is constructed with external threads that interface with internal threads on the wheel itself. The protection device 1 revolves onto the wheel, which results in the threads engaging one another. The connection is maintained through the use of a set screw, thread locker, or some other common thread locking methodology. The configuration could be reversed, having the external threads on the wheel, and the internal threads on the protection device.
FIG. 4 illustrates the protection device 1 attached directly to the rim 4 using a clip interface 6. The protection device is constructed with a continuous or discrete series of clips that retain the protection device when assembled to the wheel/tire assembly. The clip can be an interference fit or snap fit onto the rim 4. As such, the clips can be internal to the rim 4 (as shown), external, or intermediate (directly into the flange 8).
FIG. 1 illustrates the protection device 1 attached to the wheel/tire assembly by means of a clamping ring 7 on the rim flange 8. The protection device 1 is compressed between the rim flange 8 and the clamping ring 7. The clamping ring 7 can be affixed to the wheel using threaded fasteners 9, keyhole lock pins, locking tabs, rivets, or other means. FIG. 5 shows a detailed view of the clamping ring 7 attached to the wheel/tire assembly using a threaded fastener 9. Although a threaded fastener is shown, it is obvious that other connection methods, such as rivets, can be used.
FIG. 6 illustrates the protection device 1 attached to the wheel/tire assembly by means of a clamping ring 7 on an intermediate body that is affixed to the wheel/tire assembly. This is to account for cases in which the rim is not suited for direct connection, as may be the case with a steel wheel that has a relatively thin section in the flange area 8. A supporting ring 10 or sectors may be added to the rim to allow the clamping ring 7 to affix to the wheel as described in Section 5(d). The ring 10 or sectors may be welded 11 or bonded to the wheel/tire assembly. FIG. 7 illustrates an alternative to welding or bonding a continuous supporting ring 10 to the wheel/tire assembly. A snap-fit or mechanical interference 12 can be used to affix the supporting ring 10 to the wheel/tire assembly.
FIG. 8 illustrates the protection device 1 attached to the wheel/tire assembly by means of a series of clips 13. Each clip 13 features a slot 27 with which the protection device mates. The clips are constructed and mounted in such a fashion to keep the protection device in tension and/or allow the use of retaining hardware to keep the protection device firmly in place. The clip 13 is designed with a contour that allows it to grip to the rim flange 8, similar to crimp-on balance weights used on passenger cars. Additionally, the clip can be separate pieces or can be made as an integrated portion of the protection device 1.
FIG. 9 illustrates the protection device 1 attached to the wheel/tire assembly by means of a circumferential clamping to the rim flange 8. The protection device 1 is constructed such that it can be clamped between the circumferential retaining device. A hose clamp 14 is an example of a circumferential retaining device that can clamp the protection device 1 radially inward to the rim flange 8. A rigid ring with a spanner is an example of a circumferential retaining device that can clamp the protection device 1 radially outward to a specially contoured rim flange 8 (not shown). Although a screw-type hose clamp is shown, any variety of well-known configurations of hose clamps can be used.
FIG. 10 illustrates the protection device 1 attached to the wheel/tire assembly using the stud 15 and/or nut 16 that fastens a multi-piece wheel together. The protection device 1 can be attached to the hardware using some type of mechanical fastener, shown herein with a jam nut 17. Alternatively, the protection device 1 can be attached without a mechanical fastener if it is clamped by the stud 15 or nut 16. Rubber grommets or similar devices can be used to dampen or mitigate vibrations, impacts, or other dynamic events that may occur on the wheel assembly. The protection device 1 may or may not use a bracket 18 or other type of standoff to attach the ring 10 to the wheel hardware. A close-up view of the connection is shown in FIG. 11.
FIG. 12 illustrates the protection device 1 attached to the wheel/tire assembly in the disc area using the lug stud 20 and/or lug nut 21 that fastens the wheel assembly to the vehicle hub 22. The protection device 1 can be attached to the hardware using some type of mechanical fastener, shown herein with a bolted connection 23/24. As described in 5(h) the protection device 1 can be attached without a mechanical fastener if it is clamped by the lug stud 20 or lug nut 21. Rubber grommets or similar devices can be used to dampen or mitigate vibrations, impacts, or other dynamic events that may occur on the wheel assembly. The protection device 1 may or may not use a bracket 18 or other type of standoff 25 to attach to the wheel hardware. A close-up view of the connection is shown in FIG. 13.
FIG. 14 illustrates the protection device 1 can be combined with the functionality of a wheel cover 26. Wheel covers can be attached to the wheel by any one or combination of methodologies, including but not limited to threaded fasteners, wire springs, attachment to assembly hardware, attachment to the lug hardware, or snap fit into the wheel, etc. (See, also, FIG. 15).
FIG. 16 illustrates the protection device 1 attached to the wheel/tire assembly using an adapter ring 29 between the protection device 1 and the stud 15 and nut 16 that fastens a multi-piece wheel together. The adapter ring 29 can be attached to the hardware using some type of mechanical fastener, shown herein with a jam nut 17. The protection device 1 is shown attached to the adapter ring 29 using a fastener 9, a clamp ring 7, and a nut 28, which may or may not be permanently affixed to the adapter ring 29.
