Claims
- 1. A self-locking quick release grip for flexible sheeting and the like comprising:
- an elongated rigid main body securable at one end to a support and having a generally semi-circular surface at the other end thereof;
- said generally semi-circular surface and the adjacent lateral edges of said main body being covered with a multiplicity of grit-like points effective to provide a self-locking grip on sheet material in pressure contact therewith;
- resilient means normally in pressure contact with said grit-like points on one lateral edge of said main body, said resilient means being momentarily deflectable away from said grit-like points to permit the edge of sheet material to be inserted or withdrawn past said grit-like points and, at other times, being effective to press the sheet material into self-locking gripping contact with said points; and
- said grit-like points on said generally semi-circular surface bing effective to supplement said last mentioned grit-like points in gripping said sheet material when draped thereover under tension.
- 2. A self-locking grip for sheet material as defined in claim 1 characterized in that said resilient means comprises spongy resilient material carried by said main body.
- 3. A self-locking grip for sheet material as defined in claim 1 characterized in that said resilient means comprises a slot extending lengthwise of said main body with one side thereof tangent to the semi-circular end thereof, said one side of said slot being covered by said grit-like points and the other side of said slot having fixed thereto a thick layer of spongy resilient material normally in resilient contact with said grit-like points on said one side of said slot.
- 4. A self-locking grip for sheet material as defined in claim 3 characterized in that said slot is L-shaped with one leg spaced beyond and extending partially across said semi-circular end of said main body and the other leg forming one side of said slot.
- 5. A self-locking grip for sheet material as defined in claim 1 characterized in that said grit like points comprise sharp-edged grit bonded to said main body.
- 6. A self-locking quick-release grip for flexible sheeting and the like comprising:
- a rigid main body securable to a support and having a generally semi-circular surface offset thereon;
- said generally semi-circular surface and a tangentially aligned lateral surface of said main body being covered with a multiplicity of grit-like points effective to provide a self-locking grip on sheet material tensioned in pressure contact over said generally semi-circular surface;
- resilient means normally in pressure contact with said grit-like points on said tangentially aligned lateral surface of said main body, said resilient means being momentarily deflectable away from said grit-like points to permit the edge of sheet material to be inserted or withdrawn past said grit-like points and, at other times, being effective to press said edge of the sheet material into self-locking gripping contact with said points on said lateral surface; and
- said grit-like points on said generally semi-circular surface being effective to supplement said grit-like points on said lateral surface to provide the self-locking grip on said sheet material when draped thereover under tension.
- 7. A self-locking quick-release grip for flexible sheeting and the like comprising:
- a rigid main body securable to a support and having a generally semi-circular surface offset thereon;
- said semi-circular surface on said main body being covered with a multiplicity of grit-like points effective to provide a self locking grip on sheet material tensioned thereover;
- a lateral grip surface on said main body adjacent said semi-circular surface on said main body;
- resilient means in pressure contact with said lateral grip surface of said main body, said resilient means permitting the edge of sheet material to be slidably inserted or withdrawn past said lateral grip surface; and
- said grit-like points on said semi-circular surface being effective to supplement said lateral grip surface to provide the self-locking grip on said sheet material when draped thereover in tension.
