Abstract: A mono-ski frame adapted for skiing in the sitting position and designed to allow a rearward and downward traverse of the upper portion of the frame relative to the lower portion during loaded conditions to enhance the carvability during the turn. The mono-ski frame includes a lower frame having a forward end and a rearward end adapted to be attached to a ski. A foot rest is attached to the forward end of the lower frame. An upper frame having a seat mounted thereon is moveable relative to the lower frame via a first link arm. The first link arm is pivotally attached at a first position to the lower frame and at a second position to the upper frame, wherein the first position is located forwardly of the second position so that the seat attached to the upper frame travels in a rearward direction under loaded conditions.

Abstract: A method and apparatus for securing a tarp in which a planar clip having an elongate opening is placed on one side of the tarp. The opening has a wide end and a narrow end. A first portion of the opening has substantially straight edges which taper towards one another. The wide end is formed in the first portion. A second portion of the opening has substantially straight edges which are substantially parallel to one another. A button having a base, a neck and a head engages the clip with a tarp therebetween thereby securing the clip to the tarp. An elastic cord is connected to a hook at one end thereof which is connected to a structural member. The other end of the elastic cord is stretched and connected to the clip at a selected location on the cord thereby securing the tarp.
