DETAILED DESCRIPTION OF THE INVENTION

As shown in FIGS. 1, 2, and 3 of the drawings, one exemplary embodiment of the supplemental tread apparatus 100 present invention is used to lock a tire 50 with a tire wall 52 for use in low pressure rough treatment situations. While the present invention discloses a double bead lock design, it is envisioned that a single side bead lock may be utilized.

The supplemental tread apparatus 100 includes the basic components of a rim 200, a bead lock 300, and a connection bolt 400.

As shown in FIGS. 1, 2, and 10-16, the rim 200 includes an inside rim face 202 connected to a spanning web 204 that connects across the rim to the other side of the rim 200. The inside rim face 202 connects across an axle distal rim end 218 to the an outside rim face 206. The axle distal rim end 218 forms an inner tire support 220 for capturing the tire wall 52 with a tire end 222 having a rounded edge 224 for support the tire wall 52 when it is bent over the rounded edge 224 of the inner tire support 220. This rounded edge 224 become import in extreme four wheeling situations such as that shown in FIG. 2 where the tire wall 52 is squeezed between the inner tire a support 220 and the exterior rock 60. This rounded edge 224 keeps the tire from cut or compromised by the inner tire support 220. Prior art designs tended to have square or even pointed edges which cut the tire wall during these situations.

Continuing in a clockwise manner, the outside rim face 206 leads down to the axle proximate rim end 208 having the first connection body 210. The first connection body 210 differs from the prior art by utilizing a shank aperture 211 connecting to a nut recess 212 on the inner side of the first connection body 210. Previous design used threaded tapped holes directly in the rim for this connection. This causes problems on the trail when the bolt head 402 sheers off from the shank 406 or the shank 406 pulls loose from the rim. This ruins the ability to provide a quick fix because either the remaining shank 406 must be unthreaded from the rim or the entire rim must be replaced. In contrast to this prior art, the configuration of the present invention allows for the bolt 400 to simply be punched out of the bolt aperture 211 and a replacement bolt 400 to be inserted. Additionally the nut recess 212 may use a rounded recess 214 so that different sized nuts and bolts can be utilized, or the preferred embodiment's faceted recess 216 may be used so that the nut is rotationally held to the rim so that only an exterior wrench is needed to tighten the bolt 400.

FIGS. 1-9, and 3 show the improved a bead lock 300 of the present invention. The bead lock 300 includes an inside lock face 302 and an outside lock face 304 connected by an axle proximate lock end 306 and an axle distal lock end 310. A second connection body 308 is formed at the axle proximate lock end 306 and defines a bolt aperture 309 for passage of the bolt shank 406 through the bead lock 300. The axle distal lock end 310 forms an outer tire support 312 having a supplemental tread 314 with an axle distal tread face 320 to reduced the pressure that is directly applied to the tire wall 52. Similarly, an axle proximate tread end 316 is provided on the axle proximate lock end 306 to protect the axle proximate end of the rim 200.

As best seen in FIG. 3, the outside lock face 304 is covered by an outer tread face 318 with a treaded pattern forming tread recesses 322 and tread extensions 324 for increased effectiveness in extreme conditions. FIG. 3 shows a circular tread pattern for use where some slippage may be desirable and FIG. 6 shows a lug type of pattern with tread lugs 326 and sharp edges 328 for use where an increased lug grip may be desirable. Thus, the tread pattern on the supplemental tread may be varied for different scenarios. Bolt head apertures 330 are provided for recessing the bolt head 402 into the tread pattern for additional protection so that the edges of the bolt head 402 don't get rounded off during extreme use situation.

As noted by FIGS. 1, 2, and 3, the bead lock 300 is clamped to the rim 200 by multiple connection bolts 400 having a bolt head 402 with a head thickness 404 that is preferably less than the supplemental tread thickness. The bolt 400 has a bolt shank 406 having a shank length 408 and threads 410 appropriate to the application. The bolt 400 is adapted to connect into a connection nut 450 that has a faceted nut body 452 with an external rim 454 having facets 456 that mate to the faceted aperture 216 on the rim 200. The nut 450 defines a central aperture 458 with threads 460 appropriate for mating to the threads 410 on the bolt shank 406.

FIGS. 17, 18, and 19 show a rim using an extending center extended paddle bead lock 300. The bead lock 300 is similar to that previously described with the addition of shaped extensions 500 that are used as the supplemental tread 314. In the preferred embodiment shown, the shaped extensions 500 are made from the same compound as the bead lock 300 and are welded to the outside lock face 304 and cross over the open center of the bead lock 300 in a star type of arrangement with mirror image shaped offset sides in relation to the axle line to provided for balancing the assembly. The open center allows access to the bolts for installing the rim on the vehicle. The shaped extension's 500 shape may vary according to the application of the assembly 100. The shaped extensions 500 provide additional traction and protection to the vehicle and may be constructed from any suitable material such as metals, rubbers, synthetics, polymers, etc. The preferred embodiment is constructed from aluminum and has the triangular shape shown in the drawings. Other shapes may be utilized. A block type shape is useful for rock crawling applications. For deep water racing such as that associated with swamp buddy racing, these may be formed in a paddle wheel configuration or a curved pattern similar to a turbine or propeller to allow for additional motivating force for the vehicle. As shown in the preferred embodiment of FIGS. 18 and 19, the shaped extensions 500 extend past the sidewall of the tire to prevent side damage to the rim or tire while providing an increased traction surface for the tire to contact obstacles for additional traction. Note that the shaped extensions 500 should not be construed as being limited to the interior rim portion of the tire, but can extend distally over the sidewall of the tire such as is known in the prior art to provide sidewall protection and auxiliary weight carrying rims for emergency situations.

FIGS. 20-23 show another embodiment of as an extending edge version of an extended paddle bead lock 300. The shaped extensions 500 are thicker for more strength and impact resistance and the extension has been reduced for less leverage on rim. Once again, the open center allows access to the bolts for installing the rim on the vehicle. The shaped extension's 500 shape may vary according to the application of the assembly 100. The shaped extensions 500 provide additional traction and protection to the vehicle and may be constructed from any suitable material such as metals, rubbers, synthetics, polymers, etc.
