Abstract
Abstract A detachable trough structure is provided by securing two strips of elastomeric material along longitudinal edge portions to form two opposing walls providing a generally V-shaped cross sectional space therebetween. The two secured strips may be stored in the form of a roll and a desired portion cut off as needed for a trough. One of the walls strips has a planar surface provided with an adhesive layer and vacuum cup formations for attaching the trough structure to a desired surface. The ends of the trough are closed in a liquid tight manner by clamping or pinching the wall ends of the trough by means of a U-shaped clamp. A coupling to couple adjacent ends of trough structure to form a longer trough structure is also provided.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
161 words
A detachable trough structure comprising a trough body formed by a first longitudinal wall having a planar outer surface, a top edge, a bottom edge and end edges, and a second longitudinal wall having a top edge, a bottom edge, and two end edges, said walls being of flexible elastomeric material and being secured together along the bottom edge of each wall in an angular spaced relationship to form a trough space therebetween having a generally V-shaped cross sectional configuration, said walls thus forming a triangular trough channel having an open top, a closed bottom, and opposed open ends, said walls being foldable at their joined bottom edges from their angularly spaced relationship to a position wherein they form a double wall strip for storage purposes, and attaching means on the planar surface of the first wall for securing the trough structure to a support surface for the collection of a liquid flowing along said support surface above the trough channel.
Claim 2
Dependent Claim
161 words
A detachable trough structure comprising a trough body formed by a first longitudinal wall having a planar outer surface, a top edge, a bottom edge and end edges, and a second longitudinal wall having a top edge, a bottom edge, and two end edges, said walls being of flexible elastomeric material and being secured together along the bottom edge of each wall in an angular spaced relationship to form a trough space therebetween having a generally V-shaped cross sectional configuration, said walls thus forming a triangular trough channel having an open top, a closed bottom, and opposed open ends, said walls being foldable at their joined bottom edges from their angularly spaced relationship to a position wherein they form a double wall strip for storage purposes, and attaching means on the planar surface of the first wall for securing the trough structure to a support surface for the collection of a liquid flowing along said support surface above the trough channel.
Claim 3
Dependent Claim
25 words
The detachable trough structure of claim 1 wherein the attaching means is a recess means in the planar surface to act as suction cup means.
Claim 4
Dependent Claim
20 words
The detachable trough structure of claim 1 wherein the attaching means is a layer of adhesive on the planar surface.
Claim 5
Dependent Claim
30 words
The detachable trough structure of claim 1 wherein the first and second walls are positively held in their spaced V-shaped cross sectional position by removable means placed between said walls.
Claim 6
Dependent Claim
65 words
The detachable trough structure of claim 1 wherein a closure is provided for an open end of the trough channel, said closure comprising a body having a wall closing off the open end, an extension on the wall containing a cavity of a V-shaped configuration compelementary to the V-shaped trough body, said cavity receiving the end of the body and thereby sealing the open end.
Claim 7
Dependent Claim
33 words
The detachable trough structure of claim 1 wherein an opening is provided in the body communicating with the trough channel; a hose connected to said opening, and pump means connected to said hose.
Claim 8
Dependent Claim
44 words
The detachable trough structure of claim 1 wherein an open end of the trough channel between the walls is closed off by a clamp device pinching the opposing wall edges at the end together to from a liquid tight joint at the space end.
Claim 9
Dependent Claim
24 words
The detachable trough structure of claim 7 wherein the attaching means comprise recess means in the planar surface to act as suction cup means.
Claim 10
Dependent Claim
22 words
The detachable trough structure of claim 7 wherein the attaching means comprise a layer of an adhesive medium on the planar surface.
Claim 11
Dependent Claim
70 words
The detachable trough structure of claim 1 wherein two adjacent trough bodies may be coupled together to form a continuous body by a coupling comprising a body, an open ended through cavity extending through said body having a general V-shaped cross section complementary to the V-shape of the trough body, the adjacent ends of said trough bodies fitting into the opposing ends of the trough cavity in the coupling body.
Claim 12
Dependent Claim
46 words
The detachable trough structure of claim 10, wherein the inner surface of the trough cavity is provided with parallel serrations for engaging the embedding into the ends of the trough bodies to thereby form a liquid tight joint therewith and a holding means for the bodies.
