Abstract

A therapeutic back stretching device that stretches and relaxes the muscles in the lumbar section of the spine as well as concomitant muscles, such as the abdominal muscles. The device includes a rigid base constructed from a strong rigid lightweight plastic material. The base has two opposed ends with a plurality of spaced parallel slots between which is selectively fit an arched insert. The insert being formed from a lightweight flexible material and includes an opening in the center thereof to accommodate the spine of a user. The insert can be fit between slots closer or further apart to vary the degree of curvature.

Claims

1. A back stretching device designed to be positioned on the ground under the lumbar portion of a user'"'"'s back, comprising:

a base formed of a rigid material having a first end and a second end, wherein each end includes at least one slot shaped and dimensioned for selectively and respectively receiving first and second ends of an insert;

one of said ends including a plurality of spaced parallel slots; and

a bendable insert having a first and second end selectively secured to said base, wherein the insert is bent into an arch and the first and second end of the insert respectively fit between slots on said first and second end of the base and is selectively adjustable between said slots to vary the height of the arch formed by said insert.

2. An exercise device according to claim 1, wherein the base has one slot at said first end and at least three parallel spaced slots at said second end.

3. An exercise device according to claim 1, wherein the insert is a lightweight plastic material.

4. An exercise device according to claim 1, wherein the base is a rigid lightweight plastic material.

5. An exercise device according to claim 1, wherein the base has an opening formed between the ends thereof to reduce the overall weight of the device.

6. An exercise device according to claim 1, wherein the insert has an opening formed between the ends thereof to accommodate a user'"'"'s spine.

7. An exercise device according to claim 1, wherein the first end of the insert is longer than the second end of the insert, thereby providing more support to a user'"'"'s lower back portion.

8. An exercise device according to claim 1, wherein the first end of the base is longer than the second end of the base, thereby providing more support to a user'"'"'s lower back portion.

9. An exercise device according to claim 1, wherein said at least one slot on the first end of the base is opened at an angle extending towards the second end of the base.

10. An exercise device according to claim 1, wherein said at least one slot on the second end of the base is opened at an angle extending towards the first end of the base.

11. An exercise device according to claim 1, wherein said first end of said base includes a cutout section to accommodate the tail bone of a user.

12. A back stretching device designed to be positioned on the ground under the lumbar portion of a user'"'"'s back, comprising:

a base formed of a rigid material having a first end with a central cutout section to accommodate a user'"'"'s tail bone and a second end, wherein each end includes at least one slot shaped and dimensioned for selectively and respectively receiving first and second ends of an insert;

one of said ends including a plurality of spaced parallel slots; and

a bendable insert having a first and second end selectively secured to said base, wherein the insert is bent into an arch and the first and second end of the insert respectively fit between slots on said first and second end of the base and is selectively adjustable between said slots to vary the height of the arch formed by said insert.

13. An exercise device according to claim 12, wherein the base has one slot at said first end and at least three parallel spaced slots at said second end.

14. An exercise device according to claim 12, wherein the insert has an opening formed between the ends thereof to accommodate a user'"'"'s spine.

15. An exercise device according to claim 12, wherein the first end of the insert is longer than the second end of the insert, thereby providing more support to a user'"'"'s lower back portion.

16. An exercise device according to claim 12, wherein the first end of the base is longer than the second end of the base, thereby providing more support to a user'"'"'s lower back portion.

17. An exercise device according to claim 12, wherein said at least one slot on the first end of the base is opened at an angle extending towards the second end of the base.
