Abstract
Abstract Silent touch fastener material adapted to releasably engage a mating surface and adapted to produce reduced sound during rapid separation of the touch fastener material from the mating surface. The material comprises a planar backing material having an engaging surface thereon contacting the backing material at discrete points and adapted to releasably engage the mating surface and means for reducing the coupling of noise-producing vibration from the backing material into the surrounding air. Various embodiments disclose the backing material as having a high mass relative to the mass of the engaging surface; a planar high mass supplemental backing material bonded to the backing material; a flexible, high mass material incorporated into the backing material; means disposed at the discrete points of attachment of the engaging surface to the backing material for suppressing the coupling of vibrations produced in the engaging surface into the backing material; and, the backing material comprising a lattice structure having low ability for transferring vibrations induced therein into the air surrounding it.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
108 words
Silent touch fastener material, to releasably engage a mating surface and adapted to produce less sound than prior art touch fasteners during rapid separation of the touch fastener material from the mating surface, said touch fastener material comprising: (a) a planar backing material having an engaging surface thereon, extending therefrom at discrete points and adapted to releasably engage the mating surface; and, (b) the backing material comprising a lattice structure having low ability for transferring vibrations induced therein into the air surrounding it thereby providing means for reducing the coupling of noise-producing vibration from said backing material into the surrounding air upon separation of said touch fastener material.
Claim 2
Dependent Claim
108 words
Silent touch fastener material, to releasably engage a mating surface and adapted to produce less sound than prior art touch fasteners during rapid separation of the touch fastener material from the mating surface, said touch fastener material comprising: (a) a planar backing material having an engaging surface thereon, extending therefrom at discrete points and adapted to releasably engage the mating surface; and, (b) the backing material comprising a lattice structure having low ability for transferring vibrations induced therein into the air surrounding it thereby providing means for reducing the coupling of noise-producing vibration from said backing material into the surrounding air upon separation of said touch fastener material.
Claim 3
Dependent Claim
17 words
The silent touch fastener material of claim 1 said lattice structure comprising at least 50% air space.
Claim 4
Dependent Claim
17 words
The silent touch fastener material of claim 2 said lattice structure comprising at least 70-% air space.
Claim 5
Dependent Claim
91 words
A touch fastener material according to claim 1 having a noise of separation of less than about 66 dB(A), at a normal rate of separation, when measured at 1 foot from the area of separation of the fastener with one component of the fastener being rigidly attached to a massive structural member chosen to contribute minimum noise to the noise of separation, measurement being made by a sound meter meeting ANSI 51.4-1983 type 1 and set to RMS, fast response and random incidence, the fastener being a hook and loop fastener.
Claim 6
Dependent Claim
18 words
A touch fastener according to claim 4 wherein the noise of separation is less than about 60 dB(A).
Claim 7
Dependent Claim
18 words
A touch fastener according to claim 4 wherein the noise of separation is less than about 54 dB(A).
Claim 8
Dependent Claim
116 words
Silent touch fastener material, to releasably engage a mating surface and adapted to produce less sound than prior art touch fasteners during rapid separation of the touch fastener material from the mating surface, said touch fastener material comprising: (a) a planar backing material having an engaging surface thereon, extending therefrom at discrete points and adapted to releasably engage the mating surface; and, (b) the planar backing material having an increased mass to provide an aerial density of the backing thereby providing means for reducing the coupling of noise-producing vibration from said backing material into the surrounding air sufficiently to reduce the sound pressure level by at least 4.2 dB upon separation of said touch fastener material.
Claim 9
Dependent Claim
116 words
Silent touch fastener material, to releasably engage a mating surface and adapted to produce less sound than prior art touch fasteners during rapid separation of the touch fastener material from the mating surface, said touch fastener material comprising: (a) a planar backing material having an engaging surface thereon, extending therefrom at discrete points and adapted to releasably engage the mating surface; and, (b) the planar backing material having an increased mass to provide an aerial density of the backing thereby providing means for reducing the coupling of noise-producing vibration from said backing material into the surrounding air sufficiently to reduce the sound pressure level by at least 4.2 dB upon separation of said touch fastener material.
Claim 10
Dependent Claim
31 words
The silent touch fastener material of claim 7 wherein: said increased mass of said backing material is produced by bonding a planar high mass supplemental backing material to said backing material.
Claim 11
Dependent Claim
23 words
The silent touch fastener material of claim 7 said increased mass material comprising a material having the qualities and characteristics of leaded vinyl.
Claim 12
Dependent Claim
15 words
