Abstract
Abstract A cleaning device for cleaning the hooked portion of hook and loop fasteners includes a body member defining a curved surface on which is mounted a strip of hooked fastener material. A debris collecting surface of sticky, resilient material is disposed adjacent one edge of said hooked fastener material in substantially tangential alignment therewith. In a preferred embodiment of the invention, the sticky surface is disposed on a replaceable, rotatable cylindrical roll. The repeated stroking movement of the hooked fastener material over the surface to be cleaned effects a loosening of debris which is collected on the sticky surface.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
99 words
A device for cleaning the hooked portion of hook and loop fasteners comprising a body member, means on said body member defining a convexly curved surface, an array of hooked fastener elements secured to said curved surface, and means providing a sticky, debris attracting surface closely adjacent one edge of said array of hook fastener elements on said curved surface in substantially tangential alignment therewith, the relative movement of said device across a debris laden hooked fastener material engaging the array of hooked fastener elements with the debris to lift the debris therefrom for collection on said sticky surface.
Claim 2
Independent Claim
99 words
A device for cleaning the hooked portion of hook and loop fasteners comprising a body member, means on said body member defining a convexly curved surface, an array of hooked fastener elements secured to said curved surface, and means providing a sticky, debris attracting surface closely adjacent one edge of said array of hook fastener elements on said curved surface in substantially tangential alignment therewith, the relative movement of said device across a debris laden hooked fastener material engaging the array of hooked fastener elements with the debris to lift the debris therefrom for collection on said sticky surface.
Claim 3
Dependent Claim
17 words
The invention as claimed in claim 1, wherein said sticky debris attracting surface comprises a resilient surface.
Claim 4
Dependent Claim
19 words
The invention as claimed in claim 2, wherein said sticky, debris attracting resilient surface is a rotatable cylindrical surface.
Claim 5
Dependent Claim
32 words
The invention as claimed in claim 3, wherein said sticky, debris attracting resilient cylindrical surface is mounted on a demountable roll, and means on said body member for rotatably supporting said roll.
Claim 6
Dependent Claim
23 words
The invention as claimed in claim 4, wherein said means for supporting said roll comprises a split mandrel extending from said body member.
Claim 7
Dependent Claim
30 words
The invention as claimed in claim 1, including gripping means for manually grasping said body member to manually draw said array of hooked fastener elements over material to be cleaned.
Claim 8
Dependent Claim
29 words
The invention as claimed in claim 6, wherein said gripping means comprises a handle extending from the opposite end of said body member from the sticky debris attracting surface.
Claim 9
Independent Claim
139 words
A device for cleaning the hooked portion of hook and loop fasteners comprising a body member, means on said body member defining a convexly curved surface, a strip of hooked fastener material secured to said curved surface, said strip of hooked fastener material having a leading edge and a trailing edge substantially parallel to the axis of curvature of said curved surface, a cylindrical roll having a sticky, debris attracting outer surface adjacent said trailing hooked material edge, and means for rotatably supporting said roll with the sticky surface thereof in substantially tangential alignment with the curved hooked fastener covered surface, the relative movement of said device across a debris laden hooked fastener material engaging the hooked fastener material of the device with the debris to lift the debris therefrom for collection on the sticky surface of said roll.
Claim 10
Independent Claim
139 words
A device for cleaning the hooked portion of hook and loop fasteners comprising a body member, means on said body member defining a convexly curved surface, a strip of hooked fastener material secured to said curved surface, said strip of hooked fastener material having a leading edge and a trailing edge substantially parallel to the axis of curvature of said curved surface, a cylindrical roll having a sticky, debris attracting outer surface adjacent said trailing hooked material edge, and means for rotatably supporting said roll with the sticky surface thereof in substantially tangential alignment with the curved hooked fastener covered surface, the relative movement of said device across a debris laden hooked fastener material engaging the hooked fastener material of the device with the debris to lift the debris therefrom for collection on the sticky surface of said roll.

Claim 16
Independent Claim
142 words
A device for cleaning the hooked portion of hook and loop fasteners comprising a body member, means on said body member defining a convexly curved surface, a strip of hooked fastener material secured to said surface, said hook material having a leading edge and a trailing edge each parallel to the radius of curvature of said curved surface, and a substantially planar surface extending substantially tangentially from said curved surface adjacent the trailing edge of said hooked material, and means providing a sticky, debris attracting surface on said planar surface with one edge of sticky surface being parallel to and closely adjacent said hooked material trailing edge, the relative movement of said device across a debris laden hooked fastener material engaging the hooked fastener material of the device with the debris to lift the debris therefrom for collection on said sticky surface.
Claim 17
Independent Claim
142 words
A device for cleaning the hooked portion of hook and loop fasteners comprising a body member, means on said body member defining a convexly curved surface, a strip of hooked fastener material secured to said surface, said hook material having a leading edge and a trailing edge each parallel to the radius of curvature of said curved surface, and a substantially planar surface extending substantially tangentially from said curved surface adjacent the trailing edge of said hooked material, and means providing a sticky, debris attracting surface on said planar surface with one edge of sticky surface being parallel to and closely adjacent said hooked material trailing edge, the relative movement of said device across a debris laden hooked fastener material engaging the hooked fastener material of the device with the debris to lift the debris therefrom for collection on said sticky surface.
