EXERCISE TIRE

Abstract

A replacement exercise bike tire that will emulate the ride characteristics and effort of a conventional bike tire that is partially deflated. The increased roll resistance imparted by the exercise tire will enhance the bike rider's workout by imparting greater pedal effort required to ride. Multiple interconnected compartments within the tire body are filled with a high viscosity material that will displace under load as the tire rotates during use emulating a flat tire.

Claims

1. An exercise bike tire comprising, an annular tire body having a tread portion, tire bead, and a plurality of interlinked independent deformable inserts within said tire body, said inserts infilled with non-compressible material for sequential deformation under tire load, said tire body having a known outer and inner transverse dimension.

2. The exercise bike tire set forth in claim 1 wherein said deformable inserts are deformable from a first position to a second position independently within the annular tire body.

3. The exercise bike tire set forth in claim 1 wherein said inserts are of a transverse dimension less than that of said tire body's known interior dimension.

4. The exercise bike tire set forth in claim 1 wherein each of said interlinked independent deformable inserts non-compressible material is in communication with one another.

5. The exercise bike tire set forth in claim 1 further comprises said non-compressible infilled material imparts variable increase tire rotational resistance under an operational load.

6. An exercise bike tire comprising, an annular tire body, contoured depending annular sidewalls having tread beads, and a tread portion between said sidewalls, a plurality of interlinked deformable inserts within said tire body, said inserts infilled with non-compressible material, an air chamber between said inserts and said tire body.

7. The exercise bike tire set forth in claim 6 wherein said air chamber has means for infill air under pressure.

DETAILED DESCRIPTION OF THE INVENTION

[0014] Referring to FIGS. 1-4 of the drawings, an exercise bike tire 10 of the invention can be seen for use on a standard bicycle 11. The exercise bike tire 10 has an annular tire body 12 with a tread portion 13 and contoured depending annular sidewalls 14A and 14B. A tire bead 15 extends from the respective sidewalls 14A and 14B for sealing engagement with a standard bicycle tire rim 16 as shown in dotted lines in FIG. 2 of the drawings.

[0015] The exercise tire 10 has a plurality of inner linked non-compressible inserts 17 which in this example are configured as elongated inner linked chambers 18, each filled with a non-compressible viscous material VM.

[0016] The respective inserts will deform under applied pressure to the tire 10 as that of the weight of the rider (load), not shown, so as to allow the tire body 12 to deform as if flat during use. The tire body 12 may have an air chamber 19 there about for infill of air to effectively regulate the corresponding deformability of the tread 13 and sidewalls 14A and 14B under load and reduce the deformation of the viscous material VM filled insert 17 under load indicated by load arrows LA which is indicative of being applied by mounting and riding of the bicycle 11 by a user, not seen.

[0017] The exercise tire 10 of the invention may be used on any standard bicycle tire rim thus providing interchangeability and universality thereto. The transverse diameter of the non-compressible insert 17 may be varied so as to reduce or eliminate the air retaining dimensions within the bike tire depending on the venues and required use.

[0018] Such an example can be seen in FIG. 4 of the drawings wherein an alternate exercise tire replacement 20 can be seen having typical tire body 21 with a tread portion 22 and depending opposed integral sidewalls 23A and 23B on a standard bike tire rim 24. A deformable non-compressible insert 25 of interconnected elongated chambers extends around and within the tire body 21. The insert 25 is of a larger transverse dimension filling more of the tire body 21 so as to be responsive to direct load onto the tread achieved during use.

[0019] Such an alternate configuration may have apertures A within the tire tread portion that assure direct force transfer from the tire body 23 under load as noted. Therefore, the insert 25 filled with a non-compressible viscous material VM will be directly engaged and distorted for increased tire resistance during rotation thus imparting a more difficult workout as if on a partially deflated or flat tire.

[0020] It will be seen that the different inserts 17 and 25 can be used thus varying the size and sectional separation of the interconnected insert chambers. The viscous material VM used for the insert chamber 17 and 25 filling may be one from a family of related materials inclusive of but not limited to synthetic resin compounds, water, sand and gel like materials, all capable of non-compressible distortion dependent on chamber configuration and interlinking properties.

[0021] It may also be possible to interconnect the respective chambers thereby providing viscous material displacement from each independent chambers during load thus increasing the effective deformation of the tire against the road surface while maintaining tire stability during use indicated in broken line arrows 26 in FIG. 1 of the drawings.

[0022] It will thus be seen that a new and novel exercise tire has been illustrated and described and it will be apparent to those skilled in the art that various changes and modifications may be made thereto without departing from the spirit of the invention.
