Abstract

This invention relates to a clamp assembly useful for attaching together two items of clothing, a garment comprising the clamp assembly, and a process for attaching two items of clothing; the clamp assembly including a circular band and a tubular resilient cover having a hollow body, and wherein the clamp is positioned in the hollow and is encased on all sides by the resilient cover.

Claims (26)

1. A clamp assembly, comprising:

i) a clamp including a circular band that can be tightened and loosened; and

ii) a tubular resilient cover having a hollow body,

wherein the clamp is positioned in the hollow and is encased on all sides by the resilient cover; and

wherein the tubular resilient cover comprises artificial or natural rubber and is compressed when the circular band is tightened;

wherein the cover has an opening for operating the clamp; and

wherein the clamp includes a screw housing mounted to the band, and a worm screw disposed in the screw housing for engaging and positioning the band.

2. The clamp assembly of claim 1 wherein the opening is a slit in the tubular resilient cover.

3. The clamp assembly of claim 1 wherein the tubular resilient cover is a tube having first and second ends and the opening in the cover is formed by inserting a first end of the tube into the second end.

4. The clamp assembly of claim 1 wherein tubular resilient cover has a D-shaped cross-section.

5. A garment comprising a glove layer attached to a sleeve layer by a clamp assembly and a support ring, the clamp assembly comprising

i) a clamp including a circular band; and

ii) a tubular resilient cover having a hollow body,

wherein the clamp is positioned in the hollow and is encased on all sides by the resilient cover; and

wherein the clamp compresses the sleeve layer and glove layer between the clamp assembly and the support ring;

wherein the cover has an opening for operating the clamp; and

wherein the clamp includes a screw housing mounted to the band, and a worm screw disposed in the screw housing for engaging and positioning the band.

6. The garment of claim 5 wherein the opening is a slit in the tubular resilient cover.

7. The garment of claim 5 wherein the tubular resilient cover is a tube having first and second ends and the opening in the cover is formed by inserting a first end of the tube into the second end.

8. The garment of claim 5 wherein tubular resilient cover has a D-shaped cross-section.

9. A process for attaching a first item of clothing to a second item of clothing, each item of clothing comprising at least one material layer, comprising the steps of:

a) providing a support;

b) placing on an outside surface of the support one material layer from the first item of clothing and one material layer from the second item of clothing;

c) applying a clamp assembly to sandwich the first and second material layers together between the support and the clamp assembly,

the clamp assembly comprising a clamp including a circular band and a tubular resilient cover having a hollow body, wherein the clamp is positioned in the hollow and is encased on all sides by the resilient cover, and

wherein the resilient cover has an opening for operating and accessing the clamp and the clamp includes a screw housing mounted to the band and a worm screw disposed in the screw housing for engaging and positioning the band.
