A rapid locking and quick release article retaining means comprising: first and second clamp members, an elongate thrust member supporting the second clamp member for movement in a predetermined direction with respect to the first clamp member to permit variation in separation distance between the clamp members, a manually operable unidirectional drive means for producing relative movement between the first and second clamp members to produce a required relative clamping displacement between the first and second clamp members, including a tiltable element engaged by the thrust member so as to be tiltable relative to said predetermined direction, the tiltable element being arranged for positioning between a thrust member engaging position and a released position relative to the thrust member, spring means urging the tiltable element into said released position, and a manually operable member co-operating with the tiltable element for alternately positioning the tiltable element into the engaging position to cause the thrust member to move by a predetermined extent in said clamping direction and to said released position in which the tiltable element returns to its initial position; a lock for selectively preventing movement of the thrust member, and a lock release for permitting movement of the thrust member. 3. Apparatus as claimed in claim 1 or 2 further comprising a second tiltable element resiliently biased toward a position in which the tiltable element prevents reverse movement of the thrust member. 4. Apparatus as claimed in claim 3 further comprising a manually operated lever connected to the second tiltable element for moving the second tiltable element to its release position allowing said reverse movement of the thrust member. 5. Apparatus as claimed in claim 3 further comprising a handle arrangement including a manually operable lever operationally connected with said second tiltable element, the lever being pivotable between an actuated position in which the second tiltable element is moved against a second spring means to an operated position and a rest position in which the second tiltable element returns to a released position. 6. Apparatus as claimed in either claim 1 or 2 further comprising clamping surfaces selectively engagable with the first and second clamp members so that the clamping surfaces face toward each other or face away from each other. 7. Apparatus as claimed in claim 6 wherein the clamp members are rotatable relative to each other. 8. Apparatus as claimed in claim 1 or claim 2 further comprising a handle arrangement including a manually operable lever operationally connected with said tiltable element, the lever being pivotable between an actuated position in which the tiltable element is moved against said spring means to an operated position and a rest position in which the tiltable element returns to a released position. 9. Apparatus as claimed in claim 1 or claim 2 further comprising an elongate support whose longitudinal axis coincides with said predetermined direction, the elongate support having a bore engaged by said thrust member in such manner as to allow relative displacement between the first clamp member and the elongate support. 10. Apparatus as claimed in claim 9, further comprising an elongate slot provided in the elongate support, the slot extending over the range of displacement of the thrust member within the elongate support, and a thrust element engaging with the outer surface of the elongate support that is coupled to an end region of the portion of the thrust member engaging in the elongate support. 11. Apparatus as claimed in claim 9, further comprising an axially displaceable member coupled to the elongate support, the axially displaceable member adapted to provide a further clamping element, which in conjunction with said thrust element, converts the article retaining means to a sash form of cramping means for a work piece. 12. Apparatus as claimed in claim 9, wherein the elongate support is adapted for receiving extensions whereby the overall length of the elongate support can be selectively varied. 13. Apparatus as claimed in claim 1, wherein a leg of the foldable support assembly comprises an elongate support. 14. Apparatus as claimed claim 13, each of said two similar pivotally interconnected frames incorporate two leg members maintained in a pre-selectable spaced relationship by at least one connecting member, and said first clamp member is adapted for releasable connection to an upper end of one of the legs. 15.
