Abstract: An emergency key holder card which includes a credit card sized key holder card retaining emergency keys, as well as, various other incidentals. The keys may be separably retained within corresponding apertures of the card, or may be separably, hingedly attached to the emergency key holder card such that they may pivot into and out of the plane of the card. The hinge means provided pursuant to this invention allows for each key to be separated from the card at the preference of the user. Each key may be separably retained within the key holder card by means of a tab and corresponding recess arrangement, by manufacturing the key such that each non-cut edge directly abuts the corresponding key aperture edge of the key holder card, or by a separable hinge means as described above. Each key may also be separably retained within corresponding key shaped apertures.

Abstract: A demountable exercise apparatus for installation in conventional doorways comprises a pair of parallel rectangular support members each formed of separable sections. Each support member has a plurality of longitudinally spaced polygonal recesses, in opposed relation, which receive the rectangular extensible ends of a horizontal exercise cross bar. The recesses are also adapted to receive the ends of an expandable chinning bar. The cross bar height is vertically adjustable by positioning in selected octagonal recesses in the support members. The angular position of the flat surfaces of the rectangular cross bar about its longitudinal axis may be adjusted by positioning the extensible rectangular ends between opposed flats of the polygonal recess. The chinning bar may be used in conjunction with the vertically adjustable cross bar for performing a more diverse program of exercise, and the cross bar allows use of auxiliary equipment such as an inclined board, a weight beach, ropes and pulley, or several others.

Abstract: A demountable exercise apparatus for installation in conventional doorways comprises a pair of parallel rectangular support members each formed of separable or foldable lower and upper sections. Each support member is provided with a series of longitudinally spaced slots or recesses, in opposed relation, which receive the extensible ends of a horizontal exercise crossbar, and is adapted to receive the ends of an expansible chinning bar. The crossbar is vertically adjustable by positioning in selected slots or recesses in said support members. The chinning bar may be used in conjunction with the vertically adjustable crossbar for performing a more diverse program of exercise, and the crossbar allows use of auxiliary equipment such as an inclined board, a weight bench, ropes and pulley, or several others.
