Abstract
A clamping device for clamping onto a support element, the device being made of a semi-rigid material having a high coefficient of elasticity and preferably in the form of a unitary piece. The device has a peripheral portion with a geometry such as a parallelogram whereby when pressure is applied from opposite sides along the shorter axis the device expands along its longer axis. A pair of fingers are formed extending lengthwise along the longer axis, to provide gripping surfaces at about the center of the device, whereby the applied pressure moves the gripping surfaces away from the support element, and release of such pressure results in their returning into a gripping condition.
Claims13
A clamping device for clamping onto a support element made at least in part of a semi-rigid material having a high coefficient of elasticity, comprising:
- a. a unitary piece of said material;
- b. said piece of material having a peripheral portion with a geometry defining a length bounded by respective ends and a width bounded by respective sides;
- c. said piece of material having a gripping portion extending inward from said peripheral portion and being aligned substantially lengthwise relative to said peripheral portion;
- and
- said gripping portion having at least two gripping surfaces for gripping a said support element, each said gripping element extending inwardly from a respective location of said peripheral portion and presenting a convex gripping surface toward the other of said gripping elements, said two surfaces defining a space adapted to normally receive a said support element;
- and
- said side being reduced in cross sectional thickness at about the centers thereof,
- whereby pressure applied to said sides causes outward movement of said gripping surfaces to disengage a said support element, while the lack of such side pressure results in said gripping surfaces being in position for clamping contact with a said support element.
Clamping device for clamping onto a support element comprising:
- a. a unitary piece of material having a high coefficient of elasticity;
- b. said piece of material being formed to have a portion with geometry which defines a major axis and a minor axis, whereby external pressure applied inwardly and substantially perpendicular to said major axis causes elastic outward movement of said piece substantially along said minor axis;
- c. said piece having fingers extending substantially along said major axis and connected to said portion substantially adjacent opposite ends of said major axis;
- d. said fingers defining substantially convex clamping surfaces at the inner ends thereof, said surfaces being separated by a predetermined distance to define a receiving space;
- and
- e. said portion having a pressure side with a reduced thickness opposite said receiving space for receiving side external pressure.
