Abstract
A clamp for coupling together temporary fencing panels. The clamp comprises two pairs of clamping jaws, arranged side by side with jaw mouths facing the same direction. The inner jaw of each pair is hinged to the frame to allow each pair to close around an upright of the fencing panel. Between the inner jaws is a bias spring that biases the hinged jaws towards the closed position. The clamp also comprises a locking mechanism that can selectively inhibit movement of the inner jaws to hold the pairs of jaws closed in order to prevent unauthorised removal of the clamp.
Claims16
A clamp comprising two pairs of clamping jaws for clamping uprights of respective fence panels, each pair of clamping jaws comprising a fixed outer jaw and a moveable inner jaw;
- the clamp comprising a frame that provide the fixed jaws;
- each moveable inner jaw provided by a separate moveable jaw member pivotably mounted to the frame to allow rotation of the moveable inner jaws relative to their respective fixed outer jaws to open and close the clamping jaws;
- and the clamp comprises means to hold the pairs of clamping jaws closed.
A clamp according to any previous claim further comprising a bias means that connects between the moveable jaws members and adapted to bias both moveable jaw members towards their respective fixed jaw members to hold the two pairs of clamping jaws in the closed position.
A clamp according to any previous claim wherein the frame member is comprised from a single integral piece defining, at least in part, the fixed jaws.
A clamp according to any previous claim when used as a fence coupler.
A clamp when used as a fence coupler, the clamp comprising two pairs of clamping jaws, and a bias means that bias the two pairs of jaws closed.
A clamp when used as a fence coupler, the clamp comprising two pairs of clamping jaws, each pair of jaws having a mouth that face the same direction that allow the clamping jaws to be passed over parallel upright posts of adjacent fence panels when the clamp is moved laterally towards the parallel upright posts.
A clamp for clamping over circular cross section posts;
- the clamp having two pairs of clamping jaws, each pair comprised of a fixed jaw and a moveable jaw, the fixed jaws provided by a frame, each moveable jaw comprised from a moveable jaw element pivotably mounted to the frame;
- each pair of clamping jaws providing at least one arcuate clamping face to clamp against a curved outer surface of the post;
- and
- the clamp comprising a restraint mechanism to selectively retain the clamping jaws in a closed position, the restraint mechanism including a restraint member that is threadably engaged onto a threaded shaft mounted to the frame, the thread of the shaft having a lead length L;
- the restraint member arranged to be rotatable about the threaded shaft between a retaining position in which the restraint member is engaged against engagement surfaces of the moveable jaw elements to hold the two pairs of clamping jaws shut, and an open position in which the restraint member is spaced away from the engagement surfaces;
- and
- in which the engagement surfaces are arranged to move not more than a distance equating to lead length L towards or away from the restraint member during opening and closing of the two pairs of clamping jaws.
