Form-shapable tarpaulin material

Abstract

A form-shapable tarpaulin material incorporates a malleable component that enables the form-shapable tarpaulin material to be shaped into a formed shape and retain this shape. The malleable component may be coupled to a first side layer which may be a plastic layer that is waterproof. The malleable component may be continuous or discontinuous, such as including strands that form a screen or net. The malleable component may be configured between a first side layer and a second side layer, or sandwiched between these two layers. A form-shapable tarpaulin material may have a drape angle of no more than 25 degrees.

This description should be read to include one or at least one and the singular also includes the plural unless it is obvious that it is meant otherwise.

(16) Certain exemplary embodiments of the present invention are described herein and are illustrated in the accompanying figures. The embodiments described are only for purposes of illustrating the present invention and should not be interpreted as limiting the scope of the invention. Other embodiments of the invention, and certain modifications, combinations and improvements of the described embodiments, will occur to those skilled in the art and all such alternate embodiments, combinations, modifications, improvements are within the scope of the present invention.

(17) Referring now to FIGS. 1 and 2, an object 20, such as a chair 22 is covered by a form-shapable tarpaulin material 10 that is formed about the chair to create formed shape 18. The form-shapable tarpaulin material comprises a planar sheet of material 30 having a malleable component 50 that is configured to be deformed into a formed shape and will retain that shape. The formed shape may include bends or folds and the formed shape may be formed to ensure that precipitation or rain does not collect on the formed shape. As shown, the area above the seat 23 of the chair is sloped from the back 25 of the chair to the front of the seat of the chair to ensure that water does not puddle on the form-shapable tarpaulin material.

(18) Referring now to FIGS. 3 to 5, an exemplary form-shapable tarpaulin material 10 includes a planar sheet of material 30 that has a first surface layer 40 on a first surface 34, a second surface layer 60 on a second surface 36, opposing said first surface and a malleable component 50 configured between the first and second surface layers. The malleable component 50 may comprises a plurality of strands 57 formed into a screen 54 having apertures 52 between the strands, as shown in FIG. 4. A strand 57, as shown in FIG. 5, may have a curved or circular cross-sectional shape with a strand diameter 72 or a stand may be a polygonal strand 57′, being polygonal in shape having a plurality of planar sides with a stand width 74 and strand thickness 75. The malleable component 50 may have apertures 52 and an aperture width 53 between the strands. The planar sheet of material 30 has a thickness 35.

(19) Referring now to FIGS. 6 to 8, a drape test is a common and straight forward way to measure the stiffness of a fabric or material. As shown in FIG. 6, a conventional tarp material is supple and readily drapes having a drape angle of at least 75 degrees, as described herein. As shown in FIG. 7, an exemplary form-shapable tarpaulin material 10 or planar sheet of material 30 of the form-shapable tarpaulin material 10 is stiff and has a drape angle of no more than 20 degrees. As shown in FIG. 8, the drape angle 105 extends down from a horizontal axis 104 to the extended end 107 of the projected material 100. For the purposes of measuring drape angle, the projected material 100 has a length 101, as shown in FIG. 7 of 100 mm and for the material to be considered stiff according to the present invention, the drape angle under these parameters can be no more than 25 degrees and may be 15 degrees or less or even 10 degrees or less. A lower drape angle means the material is stiffer and therefore may retain a formed shape more effectively. The test specimen for the drape test may have a width, orthogonal to the projected direction, that is 100 mm.

(20) As shown in FIG. 9, an exemplary form-shapable tarpaulin material 10 has a planar sheet of material 30 and a plurality of anchor tabs 80 on the first side 31, second side 32, first end side 38 and second end side 39, as well as a fold portion 90 that is void of the malleable component 50 to allow folding of the form-shapable tarpaulin material. Also, corner anchor tabs 81 are formed by the tab gaps 86, 86′ between adjacent anchor tabs on adjacent sides. The anchor tab width 82 is shown and may be consistent across a side or may be different from one anchor tab to another. The anchor tab depth 84, the distance into the form-shapable tarpaulin material from the side, is also shown and this may be about the same dimension as the tab width or greater. There may be a gap between adjacent tabs having a tab gap width 87, that may be very small, such as no more than about 5 mm, for example. It should be noted that the strands 57 are shown in a grid buy may extend in only one direction, wherein the strands are parallel to each other and extend from the first side to the second side or alternatively from the first-end side to the second-end side. Also, a perimeter strand 58 may extend around the perimeter of the form-shapable tarpaulin material and may extend in along the tab gaps to provide additional rigidity to the anchor tabs. The perimeter strand may be different in cross-sectional shape and weight from the strands extending along or across the sheet of material 30.

(21) Referring now to FIGS. 10 and 11, an object 20 to be covered has an overhang or underside surface 24, as shown in FIG. 10. The underside is a surface, such as a planar surface that extends underneath of a portion of an object with respect to vertical. A table when standing vertically with a horizontal table top has a top surface and an opposing underside of the table top, for example. An exemplary form-shapable tarpaulin material 10 is configured over the object 20 with the anchor tabs 80 folded under the underside surface 24 to retain the form-shapable tarpaulin material 10 on the object to be covered, as shown in FIG. 11. Note that a corner anchor tab 81 is folded and additional anchor tabs 80 hold the corner tab in place. The anchor tabs may extend along the underside and may be substantially orthogonal (within 15 degrees of orthogonal) to a side surface 28 of the object to be covered. The anchor tabs are configured to retain this folded shape to retain the form-shapable tarpaulin material over the object.

(22) As shown in FIG. 12 a malleable component 50 has cells 56 with a cell width or aperture width 53, the largest dimension across the cell, that is the substantially the same, within 20% of the same value, from cell to cell. The malleable component may be referred to as a screen 54, wherein the percent open area is more than 70%. The cells 56 of this screen 54 are polygonal in shape, hexagons, wherein the strands 57 extend between adjacent cells. The cells have linear sides formed by the strands. This polygonal shape may enable formation of curved formed shapes as there are many planes along which to bend the malleable component. As described herein this malleable component may comprises a coating 58, and the coating may substantially cover the surface of the malleable component or the screen, as described herein.

(23) It will be apparent to those skilled in the art that various modifications, combinations and variations can be made in the present invention without departing from the scope of the invention. Specific embodiments, features and elements described herein may be modified, and/or combined in any suitable manner. Thus, it is intended that the present invention cover the modifications, combinations and variations of this invention provided they come within the scope of the appended claims and their equivalents.
