Abstract

The invention relates to an embroidery frame and a frame cover configured to mate with the fabric frame and align a fabric frame opening with a frame cover opening to provide a single embroidery frame opening, where the frame cover has a plurality of engagement members adapted to releasably engage the fabric frame and cover the gripper strips.

Claims

1. An embroidery frame, comprising:

at least one pair of gripper strips;

a fabric frame having

a fabric frame opening,

a top surface,

a bottom surface, and

at least one pair of recesses formed in the top surface of the fabric frame, wherein the at least one pair of recesses are arranged across the fabric frame opening and configured to receive the at least one pair of gripper strips;

a frame configured to mate with the fabric frame and having

a frame cover opening corresponding in size and geometry to the fabric frame opening,

an inner surface, and

a plurality of engagement members extending inwardly and adapted to releasable engage the bottom surface of the fabric frame and align the frame cover opening above the fabric frame opening, wherein the inner surface of the frame cover runs substantially parallel to the top surface of the fabric frame,

wherein engagement of the frame cover to the fabric frame results in the frame cover overlaying the at least one pair of gripper strips received by the at least one pair of recessed formed in the top surface of the fabric frame.

2. The embroidery frame of claim 1, wherein the fabric frame is a unitary structure.

3. The embroidery frame of claim 1, wherein the fabric frame comprises at least three legs.

4. The embroidery frame of claim 1, wherein the fabric frame and frame cover are plastic.

5. The embroidery frame of claim 1, wherein the fabric frame is a rounded rectangle.

6. The embroidery frame of claim 5, wherein the frame cover has an arched cut away at each corner.

7. The embroidery frame of claim 1, wherein the at least one pair of gripper strips are adhered in the at least one pair of recesses.

8. The embroidery frame of claim 1, wherein the at least one pair of recesses have retaining ridges configured to secure the at least one pair of gripper strips.

9. The embroidery frame of claim 1, wherein the frame cover is made of a flexible plastic.

10. The embroidery frame of claim 1, wherein the frame cover further comprises a plurality of grasping means.

11. The embroidery frame of claim 1, wherein the top surface of the fabric frame has a downward curvature running from an inner edge of the top surface to the bottom of the fabric frame.

12. The embroidery frame of claim 11, wherein the fabric frame is a rounded rectangle having four sides at right angles to one another and a leg at each corner.

13. The embroidery frame of claim 12, wherein the fabric frame is a unitary plastic structure and there is a single recess on each of the four sides.

14. The embroider frame of claim 13, wherein the frame cover is a rounded rectangle having an arched cut away at each corner and two engagement members on opposing sides and wherein the frame cover is made of flexible plastic.

15. An embroidery method for reducing stress to the base fabric, the method comprising:

stretching a base fabric over a fabric frame having

a fabric frame opening,

a top surface,

a bottom surface,

at least one pair of recesses formed in the top surface, and

at least one pair of gripper strips disposed in the at least one pair of recesses;

attaching a frame cover configured to mate with the fabric frame, wherein the frame cover comprises

a frame cover opening corresponding in size and geometry to the fabric frame opening,

an inner surface, and

a plurality of engagement members adapted to releasably engage the bottom surface of the fabric frame;

aligning the frame cover opening above the fabric frame opening and covering the at least one pair of gripper strips; and

preventing the force generated by passing a needle and one or more threads through the base fabric to produce an image on the base fabric from at least partially disengaging the base fabric from the gripper strips.

16. The method according to claim 15, further comprising producing the fabric frame as a unitary structure.

17. The method according to claim 15, wherein producing the fabric frame as a unitary structure comprises injection molding plastic.

18. The method according to claim 17, comprising providing a plastic frame cover.

19. The method according to claim 15, comprising providing a generally rectangular fabric frame.

20. The method according to claim 15, comprising providing the top surface of the fabric frame with a downward curvature running from an inner edge of the top surface to the bottom of the fabric frame.

21. The method according to claim 20, comprising producing the fabric frame as a generally rectangular unitary plastic structure and adhering a gripper strip on each side of the generally rectangular fabric frame.

22. An embroidery frame, comprising:

at least one pair of gripper strips;

a fabric frame having

a fabric frame opening,

a top surface,

a bottom surface, and

at least one pair of recesses formed in the top surface of the fabric frame, wherein the at least one pair of recesses are arranged across the fabric frame opening and configured to receive the at least one pair of gripper strips;

a frame configured to mate with the fabric frame and having

a frame cover opening corresponding in size and geometry to the fabric frame opening,

an inner surface, and

a plurality of engagement members extending inwardly and adapted to releasable engage the bottom surface of the fabric frame and align the frame cover opening above the fabric frame opening, wherein the inner surface of the frame cover runs substantially parallel to the top surface of the fabric frame, wherein engagement of the frame cover to the fabric frame results in the frame cover overlaying the at least one pair of gripper strips received by the at least one pair of recessed formed in the top surface of the fabric frame, wherein the at least one pair of gripper strips are adhered in the at least one pair of recesses.
