Abstract:

A long colored ribbon streamer is bundled preferably in zig-zag fashion in and transversely of the length of an envelope adapted to be releasibly fastened to an upper surface of a ski when skiing in deep powder snow. An end of the streamer is adapted to be fastened to the ski when skiing in the deep powder, while the envelope itself is adapted to be fastened to the skier usually through his or her ski boot. A fall in the snow that releases the ski boot and skier from the ski will cause the streamer to trail the ski at the surface of the snow that covers the ski, thereby revealing the ski's location to the skier.

Abstract:

Drywall sheets and other construction materials may be more easily transferred into and within a partially completed building shell by the use of a drywall slideboard. The drywall slideboard consists of upper and lower hinge plates separated by a horizontal hinge. The upper hinge plate supports a removable top plate, which in turn supports a slide plate of a relatively low friction coefficient material. The lower hinge plate is supported by retaining members which permit the drywall slideboard to be temporarily installed upon a section of lumber stock such as a two by four for use, or alternatively the top plate and slide plate may be easily removed from the remainder of the slideboard. Methods of use are further described in which the drywall slideboard may be installed over a two by four or similar material at a window opening and used to facilitate the transfer of building materials into or out of the structure, or alternatively the drywall slideboard may be used to transfer materials up or down a stairway when only the top plate and slide plate are used.
