Fabric retaining clip having crenated-serrated jaw assembly

1. A fabric-retaining structure comprising:

a body; and

a fabric-gripping jaw arrangement coupled to the body,

a crenated jaw having non-uniform, rounded teeth, wherein a distance between peaks of neighboring teeth in the crenated jaw is non-uniform;

a serrated jaw having serrated teeth, the serrated jaw being arranged in opposition to the crenated jaw;

wherein the jaw arrangement includes a substantially zero-offset teeth configuration, a medium offset teeth configuration and a plurality of substantially completely offset teeth configuration wherein, in an insertion direction from a mouth of the jaw arrangement towards a fabric collection cavity, said teeth configurations are encountered in the following order: first, the substantially zero-offset teeth configuration; second, the medium-offset teeth configuration; third, the substantially completely-offset teeth configuration; and fourth, the other substantially completely-offset teeth configuration.

2. A fabric-retaining structure comprising:

a body; and

a fabric-gripping jaw arrangement coupled to the body, the arrangement including

a crenated jaw having non-uniform crenated teeth, wherein a distance between peaks of neighboring teeth in the crenated jaw is non-uniform; and

a serrated jaw having serrated teeth, the serrated jaw being arranged in opposition to the crenated jaw;

each of the crenated and serrated jaw having an end proximal to the body and an end distal to the body;

the jaw arrangement having one of the following orientations:

the distal ends of the jaws being located near to each other and the proximal ends of the jaws being located near to each other; and

the distal end of the crenated jaw being located near the proximal end of the serrated jaw and the proximal end of the crenated jaw being located near the distal end of the serrated jaw wherein the jaw arrangement includes a substantially zero-offset teeth configuration, a medium offset teeth configuration and a plurality of substantially completely offset teeth configurations wherein, in an insertion direction from a mouth of the jaw arrangement towards a fabric collection cavity, said teeth configurations are encountered in the following order: first, the substantially zero-offset teeth configuration; second, the medium-offset teeth configuration; third, the substantially completely-offset teeth configuration; and fourth, the other substantially completely-offset teeth configuration.

3. The structure of claim 2 , wherein the height of the rounded tooth at the distal end is smaller than the remaining rounded teeth.

4. The structure of claim 2 , wherein a distance between peaks of neighboring teeth in the crenated jaw is non-uniform.

5. The structure of claim 2 , wherein at least one of the teeth in the crenated jaw has a left portion and a right portion that are substantially symmetric.

6. A fabric-retaining device comprising:

a base Structure; and

pinching means, connected to the base structure, for pinching together fabric, the pinching means including

crenated jaw means having non-uniform crenated teeth, wherein a distance between peaks of neighboring teeth in the crenated jaw is non-uniform; and

serrated jaw means having serrated teeth, the serrated jaw means being configured to oppose the crenated jaw means;

wherein the pinching means includes a substantially zero-offset teeth configuration, a medium offset teeth configuration and a plurality of substantially completely offset teeth configurations wherein, in an insertion direction from a mouth of the pinching means towards a fabric collection cavity, said teeth configurations are encountered in the following order: first, the substantially zero-offset teeth configuration; second, the medium-offset teeth configuration; third, the substantially completely-offset teeth configuration; and fourth, the other substantially completely-offset teeth configuration.

7. The structure of claim 6 , wherein

the crenated jaw means has an end proximal to the base structure and an end distal to the base structure;

the crenated jaw means includes rounded teeth;

the height of the rounded tooth at the distal end is smaller than the remaining rounded teeth.

8. The structure of claim 6 , wherein at least one of the teeth in the crenated jaw has a left portion and a right portion that are substantially symmetric.
