Strip fastener for holders

Claim 2

An enclosure for sheet material adapted to be retained on a supporting structure comprising: a holder having an interior cavity for storing the sheet material; strap means integrally secured to opposite ends of said holder and adapted to encircle the supporting structure so as to be retained thereon; said strap means comprising a pair of elongated strips of resilient and flexible plasticlike composition, each strip having a plurality of rib elements projecting outwardly from one side thereof in spaced-apart relationship whereby said strips are adapted to be pressed together to interlock said rib elements in releasable securement; each of said rib elements terminates in a substantially enlarged bead extending along the length thereof; each of said rib elements includes a root portion integrally formed with a base layer common to all of said rib elements associated with a selected strip; said root portion being formed with parallel sidewalls extending between said base layer and said bead; said bead being relatively wedge-shaped in cross section having a tip and diverging surfaces extending therefrom to define a pair of side lobes on opposite sides of said bead wherein the height of said wedge-shaped bead and the width of said bead being less than the distance between opposing root portions of adjacent ones of said ribs; and the separation of said interlocked rib elements is effected by lateral displacement of said strips with respect to each other whereby said beads are forced out of communication with each other on both of said strips

Claim 3

An enclosure for sheet material adapted to be retained on a supporting structure comprising: a holder having an interior cavity for storing the sheet material; strap means integrally secured to opposite ends of said holder and adapted to encircle the supporting structure so as to be retained thereon; a first and a second exTruded, elongated, resilient and flexible strip; each of said strips being provided with a plurality of integrally formed ribs arranged in fixed parallel spaced-apart relationship on one side thereof across the width of each of said strips along the entire length thereof; each rib of said plurality terminating in a substantially thickened or enlarged bead extending along the length thereof; each of said ribs includes a root portion integrally formed with a base layer common to all of said ribs associated with each one of said first and said second members respectively; said root portion formed with parallel sidewalls extending between said base layer and said bead; said bead being relatively wedge-shaped in cross section having a tip and diverging surfaces extending therefrom to define a pair of side lobes on opposite sides of said bead, wherein the height of said wedge-shaped bead and the width of said bead being less than the distance between opposing root portions of adjacent ones of said ribs; said first strip and said second strips being adapted to be manually pressed together so that said beads of one strip releasably lock with said beads of the other strips; and wherein the separation of said locked strips is effected by lateral dislodgement of said strips with respect to each other whereby said beads are slidably urged out of communication with each other on both of said strips.

Claim 4

An enclosure for sheet material adapted to be retained on a supporting structure comprising: a holder having an interior cavity for storing the sheet material; strap means integrally secured to opposite ends of said holder and adapted to encircle the supporting structure so as to be retained thereon; a first and a second exTruded, elongated, resilient and flexible strip; each of said strips being provided with a plurality of integrally formed ribs arranged in fixed parallel spaced-apart relationship on one side thereof across the width of each of said strips along the entire length thereof; each rib of said plurality terminating in a substantially thickened or enlarged bead extending along the length thereof; each of said ribs includes a root portion integrally formed with a base layer common to all of said ribs associated with each one of said first and said second members respectively; said root portion formed with parallel sidewalls extending between said base layer and said bead; said bead being relatively wedge-shaped in cross section having a tip and diverging surfaces extending therefrom to define a pair of side lobes on opposite sides of said bead, wherein the height of said wedge-shaped bead and the width of said bead being less than the distance between opposing root portions of adjacent ones of said ribs; said first strip and said second strips being adapted to be manually pressed together so that said beads of one strip releasably lock with said beads of the other strips; and wherein the separation of said locked strips is effected by lateral dislodgement of said strips with respect to each other whereby said beads are slidably urged out of communication with each other on both of said strips.

Claim 5

The invention as defined in claim 2 wherein the length of said sidewalls is at least twice the vertical depth dimension of said thickened portion so that a substantial gap surrounds said thickened portion when said thickened portions are pressed between adjacent ribs.

Claim 6

The invention as defined in claim 2 wherein the area between adjacent ones of said ribs constitutes a receptacle for insertably receiving said beads carried by the other of said strips; and wherein said receptacle is substantially formed as a rectangle in cross section having dimensions substantially greater than the dimensions of said bead so as to permit lateral sliding disengagement of said strips when said strips are moved in opposite directions respectively.

Claim 7

The invention as defined in claim 4 wherein the height of said root portion is 0.050 of an inch and the height of said bead is 0.015 of an inch with a width of 0.042 inches.

Claim 8

The invention as defined in claim 2 wherein said bead is defined between a pair of edges extending along the opposite sides thereof; each of said edges being in communication with the opposite sidewalls of said root portions respectively by a flat surface normal to its associated sidewall; and said pair of edges being in communication via a shaped surface constituting the top of said bead.

Claim 9

The invention as defined in claim 6 wherein said shaped surface is characterized by a pair of converging surfaces extending from each of said edges to merge together in a point.

Claim 10

The invention as defined in claim 6 wherein said shaped surface is characterized by a rounded surface extending between said opposite edges.

Claim 11

The invention as defined in claim 2 wherein said bead is substantially arrow-shaped in cross section having opposite parallel edges separated by said root portion and said opposite edges being in communication with the opposite sidewalls of said root portion so as to define a pair of barbs.
