Abstract
Abstract An improvement in fastening devices of the type comprising two centrally connected resilient loops and in which each loop has an enlargement (as a bead or other ornament) at its outer end, whereby the device may be stretched around an article, as for example a tress of hair, such as a pony tail and fastened by slipping the enlargement on the end of one loop under the enlargement at the end of the other loop. The improvement provides structures wherein the two loops are formed of the resilient material in such a manner that continuous lengths of the material pass through the central contiguous area of the two loops and all loose ends of the material are held within the end enlargements in such a way as to resist being pulled apart by strain or by necking down of the resilient material in normal use of the device. The enlargements are fixedly attached, one at each end to the double loop structure, in such a manner that the two lengths of material which protrude from each enlargement are each positioned at a substantial angle to the longitudinal axis of the device.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
134 words
A fastening device comprising two centrally connected loops, each of said loops having an enlargement at its longitudinal outer end, said loops comprising resilient material, two continuous lengths of said material being in side by side relationship, clamp means holding said lengths together substantially midway of their length whereby the material of both lengths is continuous and unbroken as it passes through said clamp means, said continuous lengths of material being fastened together at each of the longitudinal outer ends thereof, each of said fastened together ends being fixedly engaged within one of said enlargements, each of said enlargements being of solid construction, whereby the entirety of the length of resilient material within said enlargement is tightly engaged by the said enlargement and relative movement of said material relative to said enlargement is inhibited.
Claim 2
Dependent Claim
134 words
A fastening device comprising two centrally connected loops, each of said loops having an enlargement at its longitudinal outer end, said loops comprising resilient material, two continuous lengths of said material being in side by side relationship, clamp means holding said lengths together substantially midway of their length whereby the material of both lengths is continuous and unbroken as it passes through said clamp means, said continuous lengths of material being fastened together at each of the longitudinal outer ends thereof, each of said fastened together ends being fixedly engaged within one of said enlargements, each of said enlargements being of solid construction, whereby the entirety of the length of resilient material within said enlargement is tightly engaged by the said enlargement and relative movement of said material relative to said enlargement is inhibited.
Claim 3
Dependent Claim
40 words
A fastening device according to claim 1, wherein the two lengths are two separate discrete pieces of resilient material, having second and third clamp means holding the free outer ends thereof together at the longitudinal outer ends of the device.
Claim 4
Dependent Claim
29 words
A fastening device according to claim 2 wherein said two enlargements are solid molded pieces in which said second and third clamp means are respectively embedded and fixedly engaged.
Claim 5
Dependent Claim
45 words
A fastening device according to claim 2 wherein each of said enlargements comprises a plurality of complimentary portions including means whereby said portions may be fixedly attached to one another to fixedly engage the clamped outer ends of resilient material and to form the enlargement.
Claim 6
Dependent Claim
61 words
A fastening device according to claim 4 wherein the plurality of portions forming each of said enlargements are provided with complementary grooves, each of said grooves being of a size to tightly accommodate a single run of said resilient material, said grooves diverging from one another as they extend radially outwardly from the interior of the enlargement to the exterior thereof.
Claim 7
Dependent Claim
74 words
A fastening device according to claim 3, wherein each of said fastened outer ends is fixedly engaged in one of said enlargements whereby two runs of material enter into each of said enlargements, said two runs of material being spread apart from one another at the points of entry into each of said enlargements, whereby the said material is held within the enlargement at substantial angles to the longitudinal axis of the fastening device.
Claim 8
Dependent Claim
62 words
A fastening device according to claim 1 wherein the two lengths of material are comprised of a single piece of said material, the free ends of which are connected together by a mechanical fastening device to form a ringlet of said material, said clamp means holding the material of said ringlet together substantially midway of its length to form said two loops.
Claim 9
Dependent Claim
60 words
A fastening device according to claim 7 wherein the continuous length of material of said ringlet opposite to said mechanical fastening device is provided with means to tightly pinch the material together adjacent the edge thereof whereby said pinched end, the free ends held together by said mechanical fastening device, and said clamp means define saId two centrally connected loops.
Claim 10
Dependent Claim
22 words
A fastening device according to claim 8 wherein said pinched end and said mechanical fastening device are fixedly engaged within said enlargements.
Claim 11
Dependent Claim
30 words
A fastening device according to claim 8, wherein said enlargements are solid molded pieces in which said pinched end and said mechanical fastening device are respectively embedded and fixedly engaged.
Claim 12
Dependent Claim
112 words
A fastening device comprising two centrally connected loops of resilient material, each of said loops having a solid enlargement at its longitudinal outer end, each of said enlargements being fixedly attached around said material whereby two runs of said material enter into each of said enlargements, the two runs of material within each of said enlargements being fastened together at the outer ends of the material within the enlargement, said two runs of material being spread apart from one another at the points of entry into each of the enlargements whereby the said material is held within each of the enlargements at substantial angles to the longitudinal axis of the fastening device.
Claim 13
Dependent Claim
112 words
A fastening device comprising two centrally connected loops of resilient material, each of said loops having a solid enlargement at its longitudinal outer end, each of said enlargements being fixedly attached around said material whereby two runs of said material enter into each of said enlargements, the two runs of material within each of said enlargements being fastened together at the outer ends of the material within the enlargement, said two runs of material being spread apart from one another at the points of entry into each of the enlargements whereby the said material is held within each of the enlargements at substantial angles to the longitudinal axis of the fastening device.
