## Abstract

A system and method for tightening and removing slack in a fitted or flat sheet and to secure the sheet to prevent the slack from returning.

## Claims

### Claim 1

A bed sheet tightening system comprising:
an elongated L-shaped base having a length; a vertical member that has a height, a top edge, and is generally curved; a horizontal member that is generally flat, the horizontal member having a width, a length, a top surface, and a bottom surface that incorporates at least two downwardly protruding ridges; wherein the curve of the vertical member extends the top edge over at least a portion of the horizontal member top surface;
an elongated roller having a length, a width and a height; a substructure that has a stadium shaped profile, the substructure having two parallel flat sections integrated with two curved sections that connect the two flat sections;
two cap members, each cap member being generally integrated with the substructure and centered on a longitudinal axis of the stadium shaped profile, each cap member having a narrowed tip portion, the narrowed tip portions pointing generally away from the substructure; and,
wherein the length of the base is generally the same as the length of the roller; the height of the vertical member of the base is less than the width of the horizontal member of the base; the height of the roller is less than the height of the vertical member of the base; and, the width of the roller is generally the same as the width of the horizontal member of the base.

### Claim 2 (depends on 1)

The system of claim 1 wherein the length of the roller is approximately nine (9) inches.

### Claim 3 (depends on 1)

The system of claim 1 wherein the caps terminate on the flat sections of the substructure, and a ridge is formed at each point of termination.

### Claim 4 (depends on 3)

The system of claim 3 wherein the ridge is constructed of soft PVC material.

### Claim 5 (depends on 1)

The system of claim 1 wherein the narrowed tip portions, the downwardly protruding ridges and the top edge of the vertical member of the base are constructed of soft PVC material.

### Claim 6

A sheet tightening system comprising:
an elongated L-shaped base having a length; a horizontal section of the L-shaped having a top surface and a bottom surface, the bottom surface having two downwardly protruding gripping portions; a vertical section of the of the L-shaped base having a top ridge configured to frictionally engage a mattress surface;
an elongated roller having a generally stadium shaped profile, having a first and a second curved end, a length that is generally the same length as the elongated base; the curved ends are narrowed and configured to grip a sheet rolled around the rollers; and,
wherein the base is sized such that, when a sheet is rolled onto the roller, the roller can be securely placed into the base such that the vertical section of the L-shape resists the roller exiting the base.

### Claim 7 (depends on 6)

The system of claim 6 wherein the length of the roller is greater than 8 inches but less than 14 inches.

### Claim 8 (depends on 6)

The system of claim 6 wherein the vertical section of the base is curved such that the center of curvature lies on the horizontal section side of the base.

### Claim 9

A bed sheet tightening kit comprising:
two elongated L-shaped bases, each having a length; a horizontal section having a bottom surface incorporating two downwardly protruding gripping portions; a vertical section having a top ridge configured to frictionally engage a mattress bottom surface;
two elongated rollers each having a generally stadium shaped profile, each having a first and a second curved end, each having a length that is generally the same length as each elongated base; and each roller having curved ends that are narrowed and configured to frictionally grip a sheet rolled around each of the rollers; and,
wherein each base is sized such that, when a sheet is rolled onto each roller, each roller can be securely placed into one base such that the vertical section of each base resists each roller exiting each base.

### Claim 10 (depends on 9)

The kit of claim 9 wherein the length of each base greater than 8 inches but less than 14 inches.
