Removable fastener
First Claim
1. A removable fastener for holding a material, comprising:
- a base having a first surface and having a geometrically-shaped protrusion spaced from said first surface;
a frame having a geometrically-shaped opening, said geometrically-shaped protrusion being freely moveable at least partially through said opening when said base and frame are in a first orientation and said geometrically-shaped protrusion being blocked from passing through said opening when said base and frame are in a second orientation in which said frame and base are engaged; and
a seat formed in said fame adapted to engage said geometrically-shaped protrusion when said base and frame are engaged in said second orientation to prevent relative movement of said frame and base;
whereby a section of material may be removably engaged and held between said frame and base without piercing said material.

Abstract
A fastener is provided for removably engaging and holding sections of material, such as a tarp, without piercing the material. One piece of the fastener is a base with one end providing a contact surface for a support structure, and the other forming a substantially elliptical flange. The second piece is a frame having an opening that substantially defines a first ellipse having a first orientation, and a second ellipse having a second orientation. The second elliptical opening is partially occluded at its opposite ends. A section of material to be engaged and held is placed over the elliptical flange. The second piece is oriented to align the first elliptical opening and the elliptical flange, and is inserted over the elliptical flange and section of material to be held. The second piece is then rotated to align the second elliptical opening and elliptical flange. In this position, the occlusions of the second elliptical opening and the ends of the elliptical flange prevent disengagement of the two pieces and hold the section of material therebetween without piercing it.

14. A removable fastener for holding material, comprising:
-
a base having a first surface and a second surface comprising a substantially elliptical flange spaced apart from said first surface;
a frame having an outer frame section surrounding an interior opening, said opening substantially defining a first ellipse having a first orientation and a second ellipse having a second orientation, said second ellipse having a partial occlusion at opposite elongate ends thereof;
said substantially elliptical flange being free to pass through said interior opening when said base and frame are in a first orientation wherein said substantially elliptical flange and said opening substantially defining a first ellipse are aligned, and said substantially elliptical flange being blocked from passing through said interior opening when said base and frame are in a second orientation wherein said substantially elliptical flange and said opening substantially defining a second ellipse are aligned, said base and frame being removably engaged in said second orientation;
whereby a section of material may be removably engaged and held between said base and said frame without piercing said material when said frame and base are in said second orientation. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A removable fastener for holding a material, comprising:
-
a first piece having a geometrically-shaped protrusion;
a second piece having a geometrically-shaped opening corresponding to said protrusion, said opening adapted to receive said protrusion in a first orientation and to cause said first and second pieces to be engaged in a second orientation; and
a seat formed in said second piece adapted to engage said protrusion to prevent relative movement of said first and second pieces when engaged;
wherein said seat extends inwardly from said geometrically-shaped opening of the second piece of said removable fastener;
whereby a section of material may be removably engaged and held between said first and second pieces when engaged without piercing said material. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
