Abstract

A mattress support device for a sofa sleeper for protecting an individual from the support bars beneath the mattress in a sofa sleeper. The mattress support device for a sofa sleeper includes a first section, a second section pivotally attached to the first section and a third section pivotally attached to the second section. The second section and the third section are pivotally attached to one another by a first hinge channel extending into an upper surface between thereof. The first section and second section are pivotally attached to one another by a second hinge channel extending into a lower surface between thereof. The first section, second section and third section are preferably comprised of a solid sheet structure with the channels formed or created within to create hinges within.

Claims

1. A mattress support device for a sofa sleeper, comprising:

a sheet member having a first section, a second section and a third section extending parallel to one another;

a first hinge channel extending longitudinally within a lower surface of said sheet member between said second section and said third section creating a hinge structure; and

a second hinge channel extending longitudinally within an upper surface of said sheet member between said first section and said second section creating a hinge structure.

2. The mattress support device for a sofa sleeper of claim 1, wherein said first hinge channel is parallel to said second hinge channel.

3. The mattress support device for a sofa sleeper of claim 1, wherein said first hinge channel and said second hinge channel each have a U-shaped cross section.

4. The mattress support device for a sofa sleeper of claim 1, wherein said wherein said first hinge channel and said second hinge channel each have a V-shaped cross section.

5. The mattress support device for a sofa sleeper of claim 1, wherein sheet member has a thickness of at least 0.02 inches at said first hinge channel and said second hinge channel.

6. The mattress support device for a sofa sleeper of claim 1, wherein said first hinge channel and said second hinge channel each have a first end and a second end, wherein said first end and said second end are tapered providing an increased thickness of said sheet member relative to a middle portion of said hinge channels.

7. The mattress support device for a sofa sleeper of claim 6, wherein said first end and said second end are curved.

8. The mattress support device for a sofa sleeper of claim 1, wherein said sheet member has a rectangular shape.

9. The mattress support device for a sofa sleeper of claim 1, including a first aperture within said first section, a second aperture within said second section and a third aperture within said third section.

10. The mattress support device for a sofa sleeper of claim 9, wherein said apertures are centrally aligned within said sections such that when said sheet member is folded said apertures are aligned within one another.

11. A mattress support device for a sofa sleeper, comprising:

a sheet member comprised of high density polyethylene having a first section, a second section and a third section extending parallel to one another;

a first hinge channel extending longitudinally within a lower surface of said sheet member between said second section and said third section creating a hinge structure; and

a second hinge channel extending longitudinally within an upper surface of said sheet member between said first section and said second section creating a hinge structure.

12. The mattress support device for a sofa sleeper of claim 11, wherein said first hinge channel is parallel to said second hinge channel.

13. The mattress support device for a sofa sleeper of claim 11, wherein said first hinge channel and said second hinge channel each have a U-shaped cross section.

14. The mattress support device for a sofa sleeper of claim 11, wherein said wherein said first hinge channel and said second hinge channel each have a V-shaped cross section.

15. The mattress support device for a sofa sleeper of claim 11, wherein sheet member has a thickness of at least 0.02 inches at said first hinge channel and said second hinge channel.

16. The mattress support device for a sofa sleeper of claim 11, wherein said first hinge channel and said second hinge channel each have a first end and a second end, wherein said first end and said second end are tapered providing an increased thickness of said sheet member relative to a middle portion of said hinge channels.

17. The mattress support device for a sofa sleeper of claim 16, wherein said first end and said second end are curved.

18. The mattress support device for a sofa sleeper of claim 11, wherein said sheet member has a rectangular shape.

19. The mattress support device for a sofa sleeper of claim 11, including a first aperture within said first section, a second aperture within said second section and a third aperture within said third section.
