Abstract: A universal platform adapter for use with a clipless pedal on a bicycle includes a body portion having upper and lower surfaces, wherein the upper surface is adapted to be engaged by a generally flat bottom surface of a shoe. A first plurality of attachment apertures is provided in a first arrangement on the lower surface of the body portion and is adapted to cooperate with a first cleat that is adapted for use with a clipless pedal on a bicycle. A second plurality of attachment apertures is provided in a second arrangement on the lower surface of the body portion and is adapted to cooperate with a second cleat that is adapted for use with a clipless pedal on a bicycle. The second arrangement defined by the second plurality of attachment apertures is different from the first arrangement defined by the first plurality of attachment apertures.

Abstract: A portable, suspendable cot used in rock climbing and the like includes a collapsible frame supporting a webbing therebetween. The frame includes linkages that pivot from a parallel orientation in a closed position to an orthogonal angle (for rectangular frames) or an acute angle (for trapezoidal frames) in an open position. The linkages further comprise couplings that complete the framework and use gravitational forces to enhance the linkages, forming a secure platform that resists warping. Cabling connects the respective linkages and supports the frame so as to be suspendable from a central apex vertically displaced from the frame. The cabling can pass through a free end of the pivoting links to guide the free end to the coupling, and preserve a closed loop for the respective elements of the frame.
