Abstract
Abstract The present invention includes a stand which is capable of gripping and supporting an article in its preferred operative position. The article contemplated may be any one of a number of calculating machines such as, without limitation, a relatively small electronic calculator or the like. In a preferred embodiment, the article and stand become integral such that, upon folding the stand in a manner hereinafter disclosed, the combined article and stand may be carried together for repeated use with one another.

Claim 1
Independent Claim
307 words
In a calculator, or the like, for imparting visual information to a viewer, a housing, internal electronic calculating means disposed within said housing for providing information to a viewer in response to input signals, said housing including foldable means for positioning said calculator upon a surface at an angle with respect to said surface such that the calculator may be operated in a conventional manner without slipping being induced as between the calculator and the surface upon which it is supported, said folding means comprising a first elongated supporting frame member extending from a left side to a right side, a first generally U-shaped leg assembly supported for pivotal movement between support and retracted positions by said first supporting frame member, said leg assembly including transversely spaced friction surfaces for engaging a surface upon which the calculator is to be positioned during use, said first supporting frame member including groove means within which said first leg assembly pivotally moves, said folding means comprising a second elongated supporting frame member extending from a left side to a right side, a second generally U-shaped leg assembly supported for pivotal movement between support and retracted positions by said second supporting frame member, said leg assembly including transversely spaced friction surfaces for engaging the surface upon which the calculator is to be positioned during use, said second supporting frame member including groove means within which said second leg assembly pivotally moves, first fastening means for holding said first frame member to the underside of the calculator housing at a first location, second fastening means for holding said second frame member to the underside of the calculator housing at a second location spaced from said first location, the length of said first leg assembly being greater than the length of said second leg assembly in order to create said angle of operation.
