Back strenghthening maching

Abstract

An improved back strengthening machine 5 having a rolling cushion assembly unit 1 contoured to firmly contact all back surfaces and strengthen all dorsal muscle groups. In addition, the back strengthening machine 5 comprises: a rolling cushion assembly unit 1, weight resistance assembly unit 2, base assembly unit 3 and a handlebar assembly unit 4. While using this machine, a user will stand onto base of base assembly unit 3, hold onto hand grips adhered to handlebar assembly unit 4, and then press onto the rolling cushion adhered to rolling cushion assembly unit 1, while aligning the elevated convex cushion shape onto the spinal location. Next, the user will use knee flexion to maintain the spinning cushion adhered to rolling cushion assembly unit 1, to spin freely up and down the user's back structures.

BACKGROUND OF THE INVENTION

[0004] 1. Field of Invention

[0005] This invention relates to back strengthening machines, specifically to such which use weight resistance during operation.

[0006] 2. Prior Art

[0007] A consumer purchases back strengthening equipment in order to exercise and strengthen all of their back muscles. Ultimately, these devices should be capable of strengthening all dorsal muscle groups.

[0008] Indeed, several designs of back strengthening machines were invented. However, these former designs only partially strengthen dorsal structures. This is clearly shown in U.S. Pat. No. 5,618,250 to Butz (1997) and U.S. patent D439, 938 S to Batca (2001) wherein, both machines lack a cushion that makes total contact with all back structures.

[0009] These cushions fail to rotate along the entire spinal column or all back structures. Ultimately, these devices only slightly activate the partial strengthening of back muscles.

[0010] Thus a later back strengthening machine depicts similar lacking design features-in example U.S. Pat. No. 6,387,024 B1 to Monti (2002). This back strengthening apparatus clearly fails to make contact with all dorsal muscle groups. The absurd shape of its back strengthening rolling cushions is two lateral components, which lack a continuous contact surface for all dorsal structures. Indeed, they fall short of any surface contact for the spinal column. Nor do these lateral cushions roll along the entire back thereby ignoring the lumbar region and lower back structures.

[0011] Conclusively, heretofore-back strengthening machines render subsequent users to succumb nonetheless, into an unbalanced strengthening of back muscles. Therefore, the need still exists for a back strengthening machine that can apply equal weight resistance to all dorsal structures.

[0012] 3. Objects and Advantages

[0013] Accordingly, besides the advanced structural aspects and optimum dorsal exercise technique of the back strengthening machine in my above patent, several objects and advantages of the present invention are: [0014] (a) to provide a back strengthening machine which enables the amount of weight resistance to be used easily adjustable; [0015] (b) to provide a back strengthening machine whose rolling cushion contour will adequately make firm contact with all back structures; [0016] (c) to provide a back strengthening machine whose embodied weight resistance will sufficiently exercise all dorsal muscle groups; [0017] (d) to provide a back strengthening machine whose advantages also include the strengthening of intervertebral muscles; [0018] (e) to provide a back strengthening machine which allows a user to perform the exercise in a standing then squatting up and down repeated motion position; [0019] (f) to provide a back strengthening machine whose muscle strengthening technique will help decrease vertebrae subluxations within the spinal column; [0020] (g) to provide a back strengthening machine whose muscle strengthening technique will help to cease the onset of back pain symptoms; [0021] (h) to provide a back strengthening machine, which will decrease the malfunctions of the spine, that cause nerves to become pinched between vertebrae. [0022] (i) to provide a back strengthening machine, which will stimulate the piezoelectric effect within the spinal column and all back structures.

SUMMARY

[0023] In accordance with the present invention an improved back strengthening machine comprises a rolling cushion assembly unit with a convex shaped center adhered to a weight resistance assembly unit, base assembly unit, and a handle bar assembly unit.

DETAILED DESCRIPTION--FIG. 1-7--PREFERRED EMBODIMENT

[0030] A preferred embodiment of the back strengthening machine of the present invention is illustrated in FIG. 1 (left side perspective view). Two metal vertical bars adhered to weight resistance assembly unit 2 (FIG. 1) insert into hollowed cubes adhered to rolling cushion assembly unit 1 (FIG. 1). The bottom vertical bar adhered to weight resistance assembly unit 2 (FIG. 1) inserts into top bar adhered to base assembly unit 3 (FIG. 1). The base bar adhered to handlebar assembly unit 4 (FIG. 1) inserts into larger base bar adhered to base assembly unit 3 (FIG. 1). Top bar adhered to handlebar assembly unit 4 (FIG. 1) inserts into larger bottom bar adhered to handlebar assembly unit 4 (FIG. 1).

Operation--FIG. 1

[0031] The manner of using the improved back strengthening machine to strengthen all dorsal muscle groups is not identical to that for back strengthening machines in present use. In operation a user will stand on top of base of base assembly unit 3, hold onto hand grips adhered to handlebar assembly unit 4, and then press onto the rolling cushion adhered to rolling cushion assembly unit 1, while aligning the elevated convex shape onto the spinal location. Next, the user will use knee flexion to maintain the spinning cushion adhered to rolling cushion assembly unit 1 to spin freely up and down the user's back structures.

[0032] During operation of the back strengthening machine a user will benefit from the strengthening of all dorsal muscle groups, thereby increasing the stability of all back structures.

Claims

1. A back strengthening machine having a rolling cushion with a convex shaped middle section attached to a weight resistance unit.

2. The back strengthening machine of claim 1 having a said rolling cushion with an innovative contour that also strengthens intervertebral muscles, thereby increasing the overall stability of all back structures.

3. The back strengthening machine of claim 1 is operated by a user during which said user will perform repetitious knee flexion to maintain spinning cushion adhered to the rolling cushion assembly unit to spin freely up and the user's back and spinal structures.

4. The back strengthening machine of claim 2 wherein during said operation said user activates the said rolling cushion with said rolling cushion assembly unit to activate weight resistance unit to freely roll up and down the back.

5. The back strengthening machine of claim 3 wherein during said operation the said user will activate the said back strengthening machine to apply an even amount of weight resistance to all back surfaces.

6. The back strengthening machine of claim 4 wherein during said operation the said user remains in a prone position on the bed cushion.

7. The back strengthening machine of claim 4 wherein during said operation the said weight resistance applied to said all back surfaces will strengthen all dorsal muscle groups and activate the piezoelectric effect to all back structures.
