Abstract
Abstract A physical exercise equipment, in the form of a pulling apparatus, having a weight, to which a string is attached, which is reeved over a number of pulleys, and a hand grip at the free end of the string. At least one of said pulleys is a displaceable lockable sheeting pulley, through the displacement of which the length of a looped portion of the string and accordingly also the length of the free end portion of the string is adjustable. The height of the sheeting pulley may be read on a scale.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
205 words
Physical exercise equipment comprising a weight, a cable means so associated with said weight as to be loaded thereby when the equipment is in use, grip means at one free end of the cable means remote from said weight, a first substantially vertical guide means, a grip end pulley which is rotatably mounted for sliding movement on said first guide means to adjust the height of the grip end of said cable means and over which the grip end portion of said cable means runs means for locking said grip end pulley to said first means at any selected posiTion between a first lower level and a second higher level, a second substantially vertical guide means extending adjacent to said first guide means and substantially coextensive therewith, a displaceable and lockable sheeting pulley which is mounted for substantially upwardly and downwardly vertical movement on said second guide means past said grip end pulley to adjust the length of the free end portion of said cable means at any position of said grip end pulley, and a top pulley which is rotatably mounted above said higher level and over which said cable means runs on its way from said sheeting pulley to said grip end pulley.
Claim 2
Dependent Claim
205 words
Physical exercise equipment comprising a weight, a cable means so associated with said weight as to be loaded thereby when the equipment is in use, grip means at one free end of the cable means remote from said weight, a first substantially vertical guide means, a grip end pulley which is rotatably mounted for sliding movement on said first guide means to adjust the height of the grip end of said cable means and over which the grip end portion of said cable means runs means for locking said grip end pulley to said first means at any selected posiTion between a first lower level and a second higher level, a second substantially vertical guide means extending adjacent to said first guide means and substantially coextensive therewith, a displaceable and lockable sheeting pulley which is mounted for substantially upwardly and downwardly vertical movement on said second guide means past said grip end pulley to adjust the length of the free end portion of said cable means at any position of said grip end pulley, and a top pulley which is rotatably mounted above said higher level and over which said cable means runs on its way from said sheeting pulley to said grip end pulley.
Claim 3
Dependent Claim
37 words
Physical exercise equipment as recited in claim 1, wherein said first and second vertical guide means are disposed on a single vertical member and said top pulley is rotatably mounted at the top of said vertical member.
Claim 4
Dependent Claim
40 words
Physical exercise equipment as claimed in claim 2 further including indicia formed upon said vertical member whereby the height of said sheeting pulley and thus the length of the free grip end portion of said cable means may be determined.
