Abstract

This portable exerciser device includes a cross strap with enlarged end portions, a central portion of the cross strap may be stood on or disposed between a door and its adjacent, supporting post. The enlarged end portions will prevent sliding movement of the cross strap by engagement of such enlarged end portions with the outside edges of the shoes of the party standing on the central cross strap portion or engagement thereof by the juncture between the door and its adjacent, supporting post. A pulley is connected with the central portion of the cross strap. A cord is connected with a first handle-stirrup, thence reeved about the pulley and thence connected with a cord connector and at a location intermediate the length of the cord. The cord connector is connected with a second handle-stirrup. The connection between the cord connector and the cord is characterized by free sliding movement during one direction of relative travel therebetween and releasable, positive stop, connection during relative travel in the other direction. A form of such connector includes a ball check cooperating with the tapered conical enclosure.

A portable exercising device comprising a flexible cross strap having a central portion of sufficient length to be retained by being stood on by a wearer of shoes or being placed between a door and its adjacent supporting post and having enlarged end portions positionable on the outside of said shoes or beyond a door and its adjacent support post to engage the same, said enlarged end portion resisting sliding movement of the cross strap when a tension is placed on a central portion thereof;

pulley means for supporting a cable means;
pulley connector means disposed between said pulley means and the central portion of said cross strap;
a pair of cord connector means for connecting first and second stirrup means to a cable means;
first and second handle-stirrup means for grasping by a user during an exercise program;
cord means having one end portion thereof connected with said first handle-stirrup means, thence reeved about said pulley means, and thence releasably connected with one of said cord connector means at a location intermediate the cord means length and removed from its other end portion;
said other of said cord means including an additional means to permit free sliding movement of said cord means when pulled in one direction and to automatically lock and stop the cord means in response to only pulling in the opposite direction of said cord means when said second handle stirrup means is held stationary.
