ABSTRACT:
An improved sled for recreational use. The sled comprises a support member which is formed in the shape of a seat to accommodate a rider in an upright position. The support member has handholds at either edge for the rider to grasp. A block of ice is coupled to the bottom side of the support member. The ice is held in place by an adjustable retention member. The retention member is made up of two support blocks which are rigidly attached to the support member. A compression block is adjustably connected to each of the support blocks by means of a locking screw disposed through the support blocks. As the screw is turned, the compression blocks move inwardly clamping the ice. In alternative embodiments of the retention member, the locking screws are replaced by springs which automatically force the support blocks inward and pieces of flexible foam rubber are used to hold the ice block in place.
