Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
145 words
Exercise apparatus for use with an associated barbell which comprises: a support for holding the body of a user in reclining position on his or her back; first and second generally vertical columns disposed on respective sides of said support; first and second bar raising arms carried respectively on said first and second generally vertical columns, each bar raising arm being mounted for vertical movement with respect to one of said columns; means for raising said bar raising arms in synchronism; and means integral with said exercise apparatus for sensing the lowering of the associated barbell to a predetermined vertical elevation and switching means integral with said exercise apparatus for automatically moving at least one switch contact upon sensing the lowering of the associated barbell to said predetermined vertical elevation and means for actuating said means for raising upon movement of said one switch contact.
Claim 2
Dependent Claim
145 words
Exercise apparatus for use with an associated barbell which comprises: a support for holding the body of a user in reclining position on his or her back; first and second generally vertical columns disposed on respective sides of said support; first and second bar raising arms carried respectively on said first and second generally vertical columns, each bar raising arm being mounted for vertical movement with respect to one of said columns; means for raising said bar raising arms in synchronism; and means integral with said exercise apparatus for sensing the lowering of the associated barbell to a predetermined vertical elevation and switching means integral with said exercise apparatus for automatically moving at least one switch contact upon sensing the lowering of the associated barbell to said predetermined vertical elevation and means for actuating said means for raising upon movement of said one switch contact.
Claim 3
Dependent Claim
47 words
