Abstract

Abstract The invention relates to an expandable tarpaulin comprising plastic or canvas materials, an X-pattern array of elasticized reinforcing and tie down straps or cords, and one or more elasticized perimeter cords. A problem with previous tarpaulins is that they are difficult to tie down over varying irregular sized loads. As a result, loose edges of tarp material flap in the wind causing distracting noise and damage to the vehicle, the load and the tarpaulin. Also the loose ends permit a wind tunnel effect which induces suction, loss of particulate loads causing road hazards. These problems are avoided by means of an expandable tarpaulin according to the invention which is characterized by a unitary expandable tarpaulin with elasticized reinforcing, tie downs, and perimeter hand holds, cord or straps. A safety reflective coating on selected portions of the tarp sheet may also be employed.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 168 words
An expandable tarpaulin assembly comprising in operative combination: a) a tarpaulin sheet having a central area and at least one marginal edge; b) at least one elasticized member disposed in association with the marginal edge of said sheet, each of said members having a retracted length shorter than the length of said marginal edge; c) a plurality of elasticized reinforcing members attached to said tarpaulin sheet; d) said elasticized reinforcing members extending in geometric, non-spider web paths across said tarpaulin sheet to provide reinforcing to said tarpaulin sheet; e) the retracted length of said elasticized reinforcing members being shorter than the length of the tarpaulin sheet along the paths of attachment to said tarpaulin sheet; and f) said elasticized members in their natural retracted condition forming gathers in said tarpaulin sheet so that the elasticized members can be stretched to expand the tarpaulin sheet to cover and secure loads of varying size with reduced tendency for wind flap damage to said tarpaulin and wind loss of load material.
Claim 2
Dependent Claim 168 words
An expandable tarpaulin assembly comprising in operative combination: a) a tarpaulin sheet having a central area and at least one marginal edge; b) at least one elasticized member disposed in association with the marginal edge of said sheet, each of said members having a retracted length shorter than the length of said marginal edge; c) a plurality of elasticized reinforcing members attached to said tarpaulin sheet; d) said elasticized reinforcing members extending in geometric, non-spider web paths across said tarpaulin sheet to provide reinforcing to said tarpaulin sheet; e) the retracted length of said elasticized reinforcing members being shorter than the length of the tarpaulin sheet along the paths of attachment to said tarpaulin sheet; and f) said elasticized members in their natural retracted condition forming gathers in said tarpaulin sheet so that the elasticized members can be stretched to expand the tarpaulin sheet to cover and secure loads of varying size with reduced tendency for wind flap damage to said tarpaulin and wind loss of load material.
Claim 3
Dependent Claim 29 words
An expandable tarpaulin as in claim 1 wherein said tarpaulin sheet is selected from a plastic laminate having reinforcing fibers sandwiched between layers of plastic, canvas, and combinations thereof.
Claim 4
Dependent Claim 28 words
An expandable tarpaulin as in claim 1 which includes material covering at least portions of said reinforcing members to provide protection and reduce snagging of said reinforcing members.
Claim 5
Dependent Claim 53 words
An expandable tarpaulin as in claim 3 wherein said covering material has spaced and aligned gaps exposing a portion of the elasticized reinforcing members to permit a user to grasp the reinforcing members, to engage a securing means to the reinforcing members, or to pass additional securing means underneath the exposed reinforcing members.
Claim 6
Dependent Claim 33 words
An expandable tarpaulin as in claim 4 wherein said marginal edge comprises at least one sleeve portion in which said marginal edge elasticized member is disposed to contain and protect said elasticized member.
Claim 7
Dependent Claim 33 words
An expandable tarpaulin as in claim 1 wherein said marginal edge comprises at least one sleeve portion in which said marginal edge elasticized member is disposed to contain and protect said elasticized member.
Claim 8
Dependent Claim 65 words
An expandable tarpaulin as in claim 6 wherein said sleeve has spaced gaps exposing the elasticized member to permit a user to grasp the exposed portion of the elasticized member to position the tarpaulin sheet, to engage a securing means to the exposed portion of the elasticized member, or to stretch the exposed portion of the elasticized member to engage it to a securing member.
Claim 9
Dependent Claim 52 words
An expandable tarpaulin as in claim 7 wherein the exposed portion of the perimeter elasticized members are formed into the shape of a loop, and which includes a clamp member at the base of the loop to maintain the permanent loop shape for use as a loop pull and a securing means.
Claim 10
Dependent Claim 39 words
An expandable tarpaulin as in claim 1 wherein said elasticized reinforcing members extend substantially beyond the perimeter edge of the tarpaulin sheet, and which include means for engaging a securing member attached to the end of said extending members.
Claim 11
Dependent Claim 55 words
An expanqable tarpaulin as in claim 1 wherein said tarpaulin sheet has four marginal edges, pairs of which intersect at corners, each of said marginal edges includes at least one elasticized member extending beyond said marginal intersection corner, and which includes means for engaging a securing member attached to the outermost end of said extension.
Claim 12
Dependent Claim 19 words
An expandable tarpaulin as in claim 10 wherein said reinforcing members are configured in at least one "X" pattern.
Claim 13
Dependent Claim 19 words
An expandable tarpaulin as in claim 1 ,wherein said reinforcing members are configured in at least one "X" pattern.
Claim 14
Dependent Claim 23 words
An expandable tarpaulin as in claim 1 which includes a plurality of cut-outs adjacent the marginal edge disposed medially of the elasticized member.
Claim 15
Dependent Claim 22 words
An expandable tarpaulin as in claim 1 which includes tie down loops secured on said tarpaulin sheet in a generally rectilinear alignment.
Claim 16
Dependent Claim 22 words
