Abstract
Abstract A spring-type embroidery hoop or knitting ring includes a plastic annular member with an interiorly-grooved surface, a spring-loaded member that fits securely with the free ends of said spring-loaded member projecting radially outwardly, and a locking member that restrains the free ends of the spring-loaded member from separating from one another more than a fixed spacing distance. A squeezing manipulation of the free ends causes them to be spaced from each other a distance less than the fixed spacing distance, while concomitantly reducing the circumferential dimension of the inner ring, so that the inner ring may be moved in or out of the groove in the outer ring in a controlled manner.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
217 words
A spring-type embroidery hoop or knitting ring comprising: (a) an outer, circular, continuous, annular ring, said outer ring having an inner perimetral groove or the like in its inner surface; (b) an inner circular ring, said inner ring having a gap and being composed of a springy material, so that said inner ring is resiliently deformable to a smaller generally circular shape than said outer ring, said inner ring being concentrically disposed within said outer ring, so that said inner ring nests in said groove; (c) two spaced-apart fingers, each of said fingers extending generally radially outwards from said inner ring at one end of said gap; and (d) restraining means comprising a clip member, said means extending between said fingers to curtail and prevent excessive lateral displacement of said two fingers away from each other beyond and greater than a fixed spacing distance upon removal of the outer ring from the inner ring, while permitting lateral movement and displacement of said two fingers towards each other, so that squeezing manipulation of said two fingers causes said two fingers to be spaced from each other a distance less than said fixed spacing distance, while concomitantly reducing the circumferential dimension of said inner ring, so that said inner ring may be moved in or out of said groove.
Claim 2
Dependent Claim
217 words
A spring-type embroidery hoop or knitting ring comprising: (a) an outer, circular, continuous, annular ring, said outer ring having an inner perimetral groove or the like in its inner surface; (b) an inner circular ring, said inner ring having a gap and being composed of a springy material, so that said inner ring is resiliently deformable to a smaller generally circular shape than said outer ring, said inner ring being concentrically disposed within said outer ring, so that said inner ring nests in said groove; (c) two spaced-apart fingers, each of said fingers extending generally radially outwards from said inner ring at one end of said gap; and (d) restraining means comprising a clip member, said means extending between said fingers to curtail and prevent excessive lateral displacement of said two fingers away from each other beyond and greater than a fixed spacing distance upon removal of the outer ring from the inner ring, while permitting lateral movement and displacement of said two fingers towards each other, so that squeezing manipulation of said two fingers causes said two fingers to be spaced from each other a distance less than said fixed spacing distance, while concomitantly reducing the circumferential dimension of said inner ring, so that said inner ring may be moved in or out of said groove.
Claim 3
Dependent Claim
48 words
The spring-type embroidery hoop or knitting ring of claim 1 in which the means of (d) is a generally rectilinear clip provided with an axial slot and a terminal opening at one end, one of said fingers extending through said slot, the other finger extending through said opening.
Claim 4
Dependent Claim
35 words
The spring-type embroidery hoop or knitting ring of claim 1 in which the means of (d) is a generally rectilinear clip provided with an axial slot, both of the spaced-apart fingers extending through the slot.
