Abstract
The disclosure relates to a clamp (18) for an elongate member (16) comprising a housing (25) through which an elongate member may extend, a clamping member (33) to engage the elongate member and a locking mechanism for pressing the clamping member against the elongate member. The locking mechanism has a rotatable input (37, 41) about a defined axis and a rotary cam means (35, 39) for converting rotation of the input into linear movement of the clamping member in said axis to effect and release engagement of the clamping member with the elongate member.
Claims9
A clamp for an elongate member comprising a housing through which an elongate member may extend, a clamping member to engage the elongate member and operating means for pressing the clamping member against the elongate member, the operating means having a rotatable input about a defined axis and a rotary cam means for converting rotation of the input between retracted and advanced positions into linear movement of the clamping member in said axis to effect and release engagement respective of the clamping member with the elongate member, wherein means are provided for pre-adjusting the operating means for the clamping member such that in said advanced position, the clamping member is fully locked with the elongate member and wherein the rotary cam means includes detent means engageable in the advanced position of the cam means to resist rotation of the cam means from the advanced position.
A clamp as claimed in any of the preceding claims, wherein detent means is provided for resisting rotation of the rotary cam means from the “fully locked” position.
A clamp as claimed in any of the preceding claims, wherein means are provided for pre-adjusting the operating means for the clamping member such that in the “fully locked” position, the clamping member locks the elongate member in the housing.
An extendible telescopic leg having a clamp or clamps as claimed in any of the preceding claims.
