Abstract: A safety device for hinged doors comprising a spring loaded wedge shaped stopper means. A bracket including a flat rectangular plate is attached to the front face along the edge near the hinge side of a hinged door at a sufficient height and out of reach from small children, by adhesive or other fastening means. A pair of opposing hinge walls are mounted orthogonally at the extremities on the front face of the rectangular plate. Said stopper means is hingedly attached to the rectangular plate by means of a hinge pin and a restoring spring. When the spring is not loaded, said stopper means is positioned naturally in an obtrusive manner in the front face gap near the hinge side created by the opening and closing of the hinged door, thereby preventing a partially opened door from being shut by small children who can accidently insert their fingers or other body parts into said gap.

Abstract: A portable, compact exerciser comprising a semi-rigid torsion member with a pair of gripping surfaces at each end. The end faces of the gripping surfaces are designed to receive detachable handles orthogonally to the longitudinal axis of the torsion member. The torsion member comprising thin walled sections running along the longitudinal axis to offer resistance to any rotational force applied about the longitudinal axis of the torsion member. In one mode of operation, the user can primarily exercise the wrists by rotating the torsion member by rotating the gripping surfaces in a direction relative to each other. In another mode of operation, by moving the detachable handles attached to the gripping surfaces back and forth relative to each other in a plane orthogonal to the longitudinal axis of the torsion member, the user can exercise forearms and other muscle groups.
