Abstract
Abstract An exercising apparatus having a support adapted for vertical mounting in a doorway or the like; a slide member received on the support for reciprocal movement therealong; a weight supported on the slide member, said slide member and weight being nonrotationally engaged with the support; and a pulley and cable mechanism mounted at the upper end of the support with the cable connected to the member for lifting and lowering the same for exercising purposes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
182 words
A simplified exercising apparatus for releasable attachment in doorways and the like comprising a rest; a rigid support of angular cross section mounted on the rest and having a remote portion of adjustable length for extensible mounting of the support in an upright position on the rest in a doorway, or the like; a first pulley mounted adjacent to the remote portion of the support; a cable extending about the pulley and toward the rest; a holder slidably mounted on the support and connected to the cable, and said holder being adapted to carry a selected number of weights, having slots therein, in stacked relation thereon so as to fit about the support for stable elevational movement therealong supported on the holder upon the application of force to the cable and about the pulley; and a bracket mounted on the remote portion of the support, said bracket being bent for fitted engagement with a door jamb upon adjustment of the length of the remote portion to secure the support in a doorway while permitting the door to be closed within the doorway.
Claim 2
Dependent Claim
182 words
A simplified exercising apparatus for releasable attachment in doorways and the like comprising a rest; a rigid support of angular cross section mounted on the rest and having a remote portion of adjustable length for extensible mounting of the support in an upright position on the rest in a doorway, or the like; a first pulley mounted adjacent to the remote portion of the support; a cable extending about the pulley and toward the rest; a holder slidably mounted on the support and connected to the cable, and said holder being adapted to carry a selected number of weights, having slots therein, in stacked relation thereon so as to fit about the support for stable elevational movement therealong supported on the holder upon the application of force to the cable and about the pulley; and a bracket mounted on the remote portion of the support, said bracket being bent for fitted engagement with a door jamb upon adjustment of the length of the remote portion to secure the support in a doorway while permitting the door to be closed within the doorway.
Claim 3
Dependent Claim
154 words
An exercising apparatus adapted to be mounted in a doorway or the like comprising an elongated telescopically adjustable support, said support having a tubular lower portion and an upper extension telescopically mounted in the lower portion and having a downwardly disposed stop; means for longitudinally extending the support for rigid mounting thereof in an upright position in a doorway or the like; means slidably mounted for elevational reciprocal movement on the support, said means and the support being of mated configuration to preclude relative rotational movement thereof; a carriage having a pulley mounted therein; means for mounting the carriage with the pulley in selected elevational positions along the support, the carriage being disposed for engagement with the stop to limit downward movement of the extension in the loWer portion of the support; and a cable connected to the slidably mounted means and passed upwardly over the pulley adapted to raise said means when tensioned.
Claim 4
Dependent Claim
154 words
An exercising apparatus adapted to be mounted in a doorway or the like comprising an elongated telescopically adjustable support, said support having a tubular lower portion and an upper extension telescopically mounted in the lower portion and having a downwardly disposed stop; means for longitudinally extending the support for rigid mounting thereof in an upright position in a doorway or the like; means slidably mounted for elevational reciprocal movement on the support, said means and the support being of mated configuration to preclude relative rotational movement thereof; a carriage having a pulley mounted therein; means for mounting the carriage with the pulley in selected elevational positions along the support, the carriage being disposed for engagement with the stop to limit downward movement of the extension in the loWer portion of the support; and a cable connected to the slidably mounted means and passed upwardly over the pulley adapted to raise said means when tensioned.
Claim 5
Dependent Claim
43 words
The apparatus of claim 2 in which the means for extending the support includes a bolt screw-threadably mounted in the upper end of the extension in alignment with the support rotatable to make fine adjustments of the overall effective length of the support.
Claim 6
Dependent Claim
167 words
In combination with a door frame having a door jamb and a door mounted in the frame for movement to and from said jamb, an exercising apparatus comprising an elongated support of angular cross section having opposite ends; a member slidably engaging the support in nonrotational relation, said member being adapted gravitationally to support a weight thereon; a rest secured on one end of the support; a pulley fastened on the support adjacent to the end thereof opposite to the rest; a weight raising cable connected to the member and extended about the pulley; and a bracket mounted on the end of the support adjacent to the pulley extending laterally from said support in a direction substantially opposite to that of the pulley for releasable fitted engagement with the door jamb in noninterfering relation to the door to secure the support in erect position in the doorway on the opposite side of the jamb from the door whereby the door can be closed without removing said apparatus.
Claim 7
Dependent Claim
167 words
