Abstract
A hook clamp has surfaces allowing the clamp to be placed on a support and clamped thereto. The surfaces are such that the clamp can be placed on the support and its weight held by the support prior to tightening.
Claims11
A support apparatus for holding a lamp comprising:
- a cylindrical support having a predetermined outer size and shape;
- and
- a clamp comprising:
- a first base portion, comprising inner surfaces including a first inner surface having a shape which is substantially the same size and shape as an outer surface of said support, said base portion including at least a first hook portion which forms a cylindrically-inner shaped notch portion having inner surfaces which are substantially the same size and shape as the outer surface of said support, said hook portion hooking over the cylindrical support to form a first portion which extends below and contacts a top of the support on a first side of the support to form a hooked area, a second portion which is substantially the same size and shape as the outer surface of said support, and which extends below said top of the support on a second side of the support, and an opening,
- a closable element, movable relative to said first portion between a first position where said opening is open, and a second position where said opening is closed,
- a closure mechanism, connected to said first portion and to said closable element, and connectable between said first portion and said closable element when said closable element is located in said second position to close said opening, and selectively tightenable to tighten inner surfaces of said hook clamp against said opening, and
- a lamp attachment portion coupled to the first base portion aligned directly below said top of the support, disposed such that substantially all the weight of said clamp is borne by said first and second portions, when said closeable element is in said first open position.

A surface holding apparatus, comprising:
- a clamp comprising:
- a support member;
- and
- a first base portion, having an inner surface at least a portion of which is approximately the same size as an outer surface of said support member having a predetermined outer size and shape, said inner surface including a top area, a first hook area which extends below said top area in a first direction, and which defines a first part of an opening to said clamp at an end of said hook area, a second area which extends on the other side of said top area from said hook area, and which includes at least a portion which has an inner surface which is substantially the same size and shape as the outer surface of said support member, and an entry portion, having surfaces which define another side of said opening against which said support member can be located;
- a closable element, which closes said opening to hold said support member therein;
- a closure mechanism, which holds said closable element to cover said opening, and adjusts a position of said closure mechanism relative to said opening to tighten and loosen relative to said support member;
- and
- a load attachment portion coupled to said first base portion, said load attachment portion being aligned directly below said top of the support member, wherein a load is attachable to a load holding area directly below said load holding area, said load being aligned directly below said top of the support member, wherein substantially all of the weight of the load is borne by said first base portion when said closeable element is in said open position.

A support apparatus for holding a load relative to a support member, comprising:
- a support member having a predetermined outer size and shape;
- a clamp comprising:
- a base portion, having an inner surface shape which is substantially the same as said predetermined outer size and shape of said support member;
- a hook element, coupled to a side of said base portion, and forming a hook area;
- said hook element also including a bottom piece, which includes a load holding area;
- a closable element, which closes around said support member when in a closed position, and when in an open position, forming an opening permitting the support member to enter the hook area, the closeable element having inner surfaces which are substantially the same size and shape as said support member;
- and
- said load holding area, located below said top of the support, wherein said load is attachable to said load holding area aligned directly below said load holding area said load being disposed substantially below said top of the support, wherein substantially all the weight of said load is borne by said hook element when said closeable element is in said first open position.
