Clamps

A clamp for slidably engaging an elongate member, having a body comprising two body parts, a through-opening formed by complementary portions of said two body parts to receive the elongate member, means of said body for a hinge connection between said body parts to one side of the through-opening formed by said body parts, clamping means on an opposite side of said through-opening from the hinge connection and spanning between said two body parts, said clamping means being displaceable to and from a clamping position, in said clamping position said clamping means drawing together said two parts about the hinge connection to reduce the size of said through-opening for grasping the elongate member when inserted therein,

• said clamping means comprising a one-piece clamping member, projecting elements of said one-piece member for engagement with the body parts and an integral portion of each said body part being releasably engaged by a respective one of said elements, when said elements are engaged with said integral portions said clamping member being pivotable on said body portions from said clamping position to a release position in which the clamping member permits the parts to pivot a limited distance apart from said clamping position.

An adjustable construction comprising at least one pair of elongate uniform cross-section members disposed side by side and a clamp connecting said members together, said clamp comprising a body formed of a plurality of parts, an opening in said body through which a first of said members projects and a series of aligned bores in at least two said body parts forming a further opening through which a second of said members projects, successive said bores of one of said at least two body parts having at least one bore of another of said parts interposed between them, whereby to lock the parts together axially on said second member, a clamping member spacing said at least two body parts and having limited displacement thereon between respective end positions, one being a clamping position in which it draws together said body parts into clamping engagement with said pair of elongate members, the other end position being a release position for the body parts, and there being retaining means for holding the clamping member in its clamping end position, the location of said second member in said aligned bores providing a pivot for said at least two body parts to permit them to move to and from the clamping engagement of the elongate members with the displacement of the clamping member to and from said clamping position.

A clamp for slidably engaging an elongate member, the clamp having a body comprising two body parts, a through-opening formed by complementary portions of said two body parts to receive the elongate member, means on said body for a hinge connection between said body parts to one side of the through-opening formed by said body parts, clamping means on an opposite side of said through-opening from the hinge connection and spanning between said two body parts, said clamping means being displaceable to and from a clamping position, in said clamping position said clamping means drawing together said two parts about the hinge connection to reduce the size of said through-opening, for grasping the elongate member when inserted therein, said clamping means comprising a one-piece clamping member, coaxial elements of said one-piece clamping member projecting to opposite sides thereof and integral portions of said body parts providing a pivot mounting releasably engaged by said coaxial elements whereby the clamping member can be engaged with both said body parts and pivoted thereon, said clamping member when engaged with said parts being pivotable on said integral portions from said clamping position to a release position in which the clamping member permits the parts to pivot a limited distance apart from said clamping position.

A clamp for slidably engaging an elongate member, said clamp having a body comprising two body parts, a through-opening formed by complementary portions of said two body parts to receive the elongate member, means on said body for a hinge connection between said body parts to one side of the through-opening formed by said body parts, clamping means on an opposite side of said through-opening from the hinge connection and spanning between said two body parts, said clamping means being displaceable between clamping and release positions, in said clamping position said clamping means drawing together said two parts about the hinge connection to reduce the size of said through-opening, for grasping the elongate member when inserted therein, said clamping means comprising a one-piece clamping member having projecting elements for engaging with the body parts, the body parts having respective snap-fitting engagement elements forming coaxial mountings receiving the respective projecting elements of the clamping member formed in the body parts, the clamping member being pivotable between the clamping and release positions while mounted in said snap-fitting engagements, the clamping member permitting the body parts to pivot a limited distance apart from said clamping position when in said release position.
