Abstract
Abstract An attachment device comprising a filament having a laterally oriented bar at one end and a hollow body member at its other end, a wall of said body member having an opening therethrough large enough to receive the filament and the bar when they are in parallel orientation but of a width smaller than the length of the bar so as to prevent the withdrawal of the bar from the hollow interior subsequent to insertion, a self-contained, interlocked attachment thereby being obtained.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
168 words
An attaching device comprising a filament having a normally laterally oriented bar at one end and a hollow body member at its other end, at least one wall of said body member having an opening therethrough leading into the hollow interior of said member, said hollow interior having a greater width than said opening, an abutment defined therebetween, said filament being passable through said opening and said bar having a length greater than the maximum width of said opening and a thickness such that it is passable through said opening when said bar is oriented in a direction generally parallel to said filament, said bar when in a direction other than generally parallel to said filament being receivable in said hollow interior and engageable with said abutment, said body member comprising a two piece assembly wherein said pieces are secured to one another, one of said pieces being integrally connected to said filament, with one piece being an open-ended tube and the other piece being a closed-ended tube.
Claim 2
Dependent Claim
168 words
An attaching device comprising a filament having a normally laterally oriented bar at one end and a hollow body member at its other end, at least one wall of said body member having an opening therethrough leading into the hollow interior of said member, said hollow interior having a greater width than said opening, an abutment defined therebetween, said filament being passable through said opening and said bar having a length greater than the maximum width of said opening and a thickness such that it is passable through said opening when said bar is oriented in a direction generally parallel to said filament, said bar when in a direction other than generally parallel to said filament being receivable in said hollow interior and engageable with said abutment, said body member comprising a two piece assembly wherein said pieces are secured to one another, one of said pieces being integrally connected to said filament, with one piece being an open-ended tube and the other piece being a closed-ended tube.
Claim 3
Dependent Claim
18 words
The attachment of claim 1, wherein said laterally oriented bar extends substantially at right angles to said filament.
Claim 4
Dependent Claim
31 words
The attachment of claim 2, wherein a plurality of projections extend laterally into said opening from the wall surrounding said opening to facilitate retention of said bar in said hollow interior.
Claim 5
Dependent Claim
13 words
The attachment of claim 3, which is constituted by a molded plastic assembly.
Claim 6
Dependent Claim
31 words
The attachment of claim 1, wherein a plurality of projections extend laterally into said opening from the wall surrounding said opening to facilitate retention of said bar in said hollow interior.
Claim 7
Dependent Claim
13 words
The attachment of claim 1, which is constituted by a molded plastic assembly.
Claim 8
Dependent Claim
21 words
The attachment of claim 1, wherein said pieces are connected along a line generally perpendicular to the axis of said opening.
Claim 9
Dependent Claim
158 words
An assembly of a plurality of attachments, each attachment comprising a filament having a normally laterally oriented bar at one end and a hollow member at its other end, at least one wall of said body member having an opening therethrough leading into the hollow interior of said member, said hollow interior having a greater width than said opening, an abutment defined therebetween, said filament being passable through said opening and said bar having a length greater than the maximum width of said opening and thickness such that it is passable through said opening when said bar is oriented in a direction generally parallel to said filament, said bar when in a direction other than generally parallel to said filament being receivable in said hollow interior and engageable with said abutment; said assembly comprising a mounting element and a connector between said mounting element and each laterally oriented bar, whereby said bar is connected to said mounting element.
Claim 10
Dependent Claim
158 words
An assembly of a plurality of attachments, each attachment comprising a filament having a normally laterally oriented bar at one end and a hollow member at its other end, at least one wall of said body member having an opening therethrough leading into the hollow interior of said member, said hollow interior having a greater width than said opening, an abutment defined therebetween, said filament being passable through said opening and said bar having a length greater than the maximum width of said opening and thickness such that it is passable through said opening when said bar is oriented in a direction generally parallel to said filament, said bar when in a direction other than generally parallel to said filament being receivable in said hollow interior and engageable with said abutment; said assembly comprising a mounting element and a connector between said mounting element and each laterally oriented bar, whereby said bar is connected to said mounting element.
Claim 11
Dependent Claim
31 words
The assembly of claim 7, wherein a plurality of projections extend laterally into said opening from the wall surrounding said opening to facilitate retention of said bar in said hollow interior.
Claim 12
Dependent Claim
34 words
The assembly of claim 8, wherein securing means are interposed between and connected to said body members to secure said members together, said securing means being comparatively more readily severable than said frangible means.
Claim 13
Dependent Claim
31 words
The assembly of claim 10, wherein said body members are arranged essentially parallel to one another with facing surfaces, said securing means being interposed between and secured to said facing surfaces.
Claim 14
Dependent Claim
12 words
The assembly of claim 8, wherein the body members are connected together.
Claim 15
Dependent Claim
15 words
The assembly of claim 12, wherein the body members are interconnected by means interposed therebetween.
Claim 16
Dependent Claim
110 words
An attachment device comprising a filamentary member, a flexible and laterally oriented bar at one end of said filamentary member and a body member at the other end of said filamentary member, said body member having an opening therein leading into a hollow interior having a width greater than said opening and an abutment defined therebetween, said filamentary member being passable through said opening and said bar having a length greater than the minimum width of said opening and a thickness such that it is passable through said opening into said hollow interior and engageable with said abutment therein when oriented in a direction generally parallel to said filamentary member.
Claim 17
Dependent Claim
110 words
An attachment device comprising a filamentary member, a flexible and laterally oriented bar at one end of said filamentary member and a body member at the other end of said filamentary member, said body member having an opening therein leading into a hollow interior having a width greater than said opening and an abutment defined therebetween, said filamentary member being passable through said opening and said bar having a length greater than the minimum width of said opening and a thickness such that it is passable through said opening into said hollow interior and engageable with said abutment therein when oriented in a direction generally parallel to said filamentary member.
