ABSTRACT:
The invention relates to means for coupling a first rigid element to a second rigid element, the coupling means including a wheel having a central circular opening therein with a screw thread on the inner surface of the central opening and a rod member including a longitudinal rod having a screw thread on the outer surface thereof. The wheel screw thread and the rod screw thread are mating threads. The wheel is received in a transverse passage extending through the width of the first rigid element in a plane at right angles to the length of the first element and the rod is received in a longitudinal passage in the first element, the passage extending from one edge of the first element into the element and being in communication with the transverse passage. The longitudinal passage is also aligned with a central opening when the wheel is received in the transverse passage, whereby the rod can extend, at one end thereof, through the longitudinal passage into the central opening so that the rod screw threads can matingly engage the screw threads of the inner surface. Engagement means, such as lugs, are disposed at the other end of the rod for couplingly engaging openings in the second rigid element.
