Abstract: A clamping device adapted to be secured on the wrist of a person and conformed to retain portable calculators of various sizes thereat. In a first embodiment the clamping device comprises an angulated base plate including wrist band receiving slots along the lateral edges thereof and provided with an outwardly extending longitudinal securing lip. The base plate surface subjacent the wrist band furthermore, includes two transverse surface recesses conformed to receive at various depths of insertion, two parallel tongues extending from a locking plate similarly provided with a longitudinal retaining lip. Both the tongues and the recesses and the interiorly opposed surfaces of the locking lip each include longitudinal serrations biased to maintain the calculator in position and to provide an engaging interface. In a second embodiment a single, unitary, structure is utilized to form the base plate, such base plate including two spirally wound longitudinal edges which by spring deformation retain the calculator.

Abstract: A support assembly for a flat soaker hose comprising a spike insertable into the ground, said spike including mounting provisions at the top end thereof for receiving a clamp assembly at various angular dispositions. The clamp assembly is conformed to provide a plurality of cantilevered fingers disposed in staggered opposing alignment, the interior separation between fingers being dimensioned to provide a clamping fit about the soaker hose. One exterior surface of said clamp is furthermore joined to a mounting structure variously conformed for attachment to the upper end of said spike at various angular alignment. In a first embodiment the upper end of the spike is provided with a planar or rectangular cavity extending vertically downward along or parallel to the axis of the spike and the support structure is conformed as a planar member having a plurality of elongate, coplanar elements extending at various angular alignments therefrom each element being conformed for receipt in said cavity.

Abstract: A universally attachable tray assembly adapted to be secured to table edges of various configurations including on the surface thereof a set of instructions regarding a particular card game, chip recesses for storing betting chips and a drink recess. The underside of the tray is provided with an orthogonal mounting surface arranged as a rectangular strip extending transversely across the tray bottom, the rectangular strip including a plurality of vertical slots formed therein for receiving securing fixtures. The vertical slots are separated by a dimension equal to the dimension separating a plurality of screw holes and slots formed in the surfaces of an angulated mounting bracket which may thus be secured in any angular arrangement to adapt to the edge configuration of the table.
