Abstract

Abstract A stand for a conventional rectilinearly shaped compact high-speed manual digital calculator is provided which is removably mountable on a table-top, desk-top or like planar support and skid resistant thereon. The stand includes a substantially rectilinear web having a first elevated end and a second descendent end contiguous to the planar support. Proximately underlying the second end of the web is a rail flange having upper and lower oblique surfaces corresponding to the angle of elevation of the web and providing a level mount therefor. Issuing generally upwardly from the second end of the web is a lip flange which provides a fixed support for a calculator overlying the web. Cooperating means are mounted in the surfaces of the stand that engage the support which render the stand substantially skid resistant thereon.

Total Claims: 2
Claim 1
Independent Claim 301 words
A supporting stand for a calculator which is removably mountable on a planar support comprising, a substantially rectilinear web having a first elevated end, and a second descendent end substantially contiguous to said planar support; a lip flange connected to said web, said lip flange issuing upwardly from said second descendent end of said web substantially normally thereto, said lip flange providing a bearing support for a calculator overlying said web; a substantially rectilinear butt flange connected to said web, said butt flange issuing downwardly substantially from said first elevated end of said web, and elevating said web at a predetermined angle of inclination relative to a horizontal plane medianly through said stand of about 45° or less a longitudinally extending rail flange connected to said web, said rail flange underlying substantially said second end of said web, and having respective upper and lower oblique surfaces, said upper oblique surface thereof being fixedly connected to said web, said upper and lower oblique surfaces defining an angle corresponding to the angle of inclination of said web and providing a level mount therefor, said butt flange and said rail flange having respective beveled planar support engaging surfaces, and including cooperating means mounted, respectively, in said beveled planar support engaging surfaces of said butt flange and said rail flange, for rendering said stand substantially skid resistant on said planar support, said means comprising a corresponding longitudinally elongated recess in each of said beveled planar support engaging surfaces provided in said butt flange and said rail flange, and a felt strip mounted in each of said recesses spaced from the side walls of said recesses to provide a clearance therebetween, each of said felt strips extending past the mouth of its respective recess to abut a planar support surface on which said stand is mounted.
