Abstract: A light which may be mounted in a corner is disclosed which utilizes a light cover having a unique configuration specifically designed to be quickly and conveniently mounted in a corner or like location, with any of several lighting arrangements being located in the corner under the light cover. The light cover is made of translucent material which will disseminate the light from a light source contained under the light cover, which consists of an essentially rectangular segment which is bent along one diagonal to form a configuration which will fit entirely in a corner. Either a fluorescent tube or one or more incandescent light bulbs may be used as the light source, which in the preferred embodiment is mounted in a socket apparatus which is installed in the corner on one or both of the surfaces forming the corner, thereby centrally locating the light source with respect to the light cover which is anchored to the wall or ceiling.

Abstract: A collapsible rigid lodgment structure erectable from a single blank and collapsible to a relatively small, compact and transportable size is shown and described. The structure when collapsed can be folded by folds and bifurcations to have an area approximately one-fourth the area of the blank from which the structure is made. When erected, the structure is generally in the form of a tetrahedron. The structure when erected is suitable for expedient use as a hut or shelter.
