Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
174 words
A hydraulic exercise device comprising, a load-bearing mast means adapted to be secured to a supporting surface; a head arranged on said mast for axial travel therealong, means for locking said head in place on said mast means and a closed hydraulic loop resistance means arranged therewith that includes a cylinder secured to said head, a piston rod and connected piston for movement against a contained fluid that includes adjustable flow restriction means therewith; handlebar means arranged to be vertically pivotally movable on said head and is connected to said piston rod to translate that vertical movement into piston movement against said contained fluid; and laterally spaced mounting means secured to said head releasably attaching a chest exercise portion for operation by a bodybuilder comprising a pair of outstanding arms arranged to be gripped and moved apart and back together in a generally horizontal plane by a bodybuilder, said arms being connected to respective ends of a piston cylinder assembly comprising a closed hydraulic loop means providing a controlled resistance to that arm movement.
Claim 2
Dependent Claim
174 words
A hydraulic exercise device comprising, a load-bearing mast means adapted to be secured to a supporting surface; a head arranged on said mast for axial travel therealong, means for locking said head in place on said mast means and a closed hydraulic loop resistance means arranged therewith that includes a cylinder secured to said head, a piston rod and connected piston for movement against a contained fluid that includes adjustable flow restriction means therewith; handlebar means arranged to be vertically pivotally movable on said head and is connected to said piston rod to translate that vertical movement into piston movement against said contained fluid; and laterally spaced mounting means secured to said head releasably attaching a chest exercise portion for operation by a bodybuilder comprising a pair of outstanding arms arranged to be gripped and moved apart and back together in a generally horizontal plane by a bodybuilder, said arms being connected to respective ends of a piston cylinder assembly comprising a closed hydraulic loop means providing a controlled resistance to that arm movement.
Claim 3
Dependent Claim
71 words
A hydraulic device as set forth in claim 1 further including, with the mast means, a leg exerciser portion for operation by a bodybuilder on a bench means that includes a hydraulic loop means arranged to provide a resistance to axial pivoting of a bar means that is pivotally coupled to said mast means and whereto foot engaging means are secured to be pivoted by a bodybuilder on said bench means.
Claim 4
Dependent Claim
65 words
A hydraulic exercise device as set forth in claim 1 or 2, wherein the hydraulic loop means includes a cylinder assembly wherein is contained the piston arranged for back and forth longitudinal travel by the connected piston rod, against a fluid contained therein, and including fluid passage means where through said fluid is displaced from said moving piston face to below said piston moving face.
Claim 5
Dependent Claim
37 words
A hydraulic exercise device as set forth in claim 3 wherein the fluid passage means is a tube whose ends connect to the cylinder assembly between the piston travel and includes the adjustable flow restriction means therein.
Claim 6
Dependent Claim
47 words
A hydraulic exercise device as set forth in claim 4 wherein the adjustable flow restriction means is a needle valve, and a gauge is connected into the tube for reading the line pressure in one direction of flow, which gauge is calibrated to indicate load in pounds.
Claim 7
Dependent Claim
41 words
A hydraulic exercise device as recited in claim 1, further including, sliding arms; hand grip means for coupling to ends of said sliding arms; and pivot means for pivotally coupling each said hand grip means to each said sliding arm end.
Claim 8
Dependent Claim
66 words
A hydraulic exercise device as recited in claim 2, wherein leg exercise portion includes, a post that is connected to the support surface to support the pivoting of the bar means; an arm that is fixed to said bar means to extend normal thereto; and the hydraulic loop means connects between the arm and the post to provide a resistance to rotation of said bar means.
Claim 9
Dependent Claim
65 words
A hydraulic exercise device as recited in claim 7 wherein the leg exercise portion includes, a first pair of oppositely projecting members supported on said bar means in proximity to the post; and a second pair of oppositely projecting members supported from the bar means, in a spaced relation to said first pair, said second pair of oppositely projecting members being separated from each other.
Claim 10
Dependent Claim
57 words
A hydraulic exercise device as set forth in claim 1 wherein, the handlebar means is arranged to provide spaced apart grips between an open center area wherethrough a bodybuilder's head can pass, the bodybuilder's shoulders to contact opposite sides of the handlebar means and including padding means for arrangement between the bodybuilder's shoulders and said handlebar means.
Claim 11
Dependent Claim
80 words
A hydraulic exercise device as set forth in claim 1, wherein, the mast means is part of a collapsible frame and includes two upright parallel posts that are spaced apart and are pivotally connected at an apex, as one side of a triangle with a brace as the other side, detachably connected at a foot end to the support surface with said brace which mast means is pivotally connected at a foot end adjacent an edge of said support surface.
Claim 12
Dependent Claim
79 words
A hydraulic exercise device as recited in claim 10 wherein, the brace includes two tubular members maintained in parallel spaced relation, connected at like ends to an edge of the support surface, the opposite tubular member ends joined by a spacer journaled therebetween to rotate about its longitudinal axis; and the mast means is connected at one end to the support-surface near its center, with the other mast means end fixed to said spacer between said brace tubular members.
Claim 13
Dependent Claim
50 words
A hydraulic exercise device as recited in claim 10, wherein, the head includes a pair of relatively short tubular sections dimensioned to telescope onto the parallel posts of the mast means, with a pair of laterally extending rods spanning between the upper and lower ends of the short tubular sections.
Claim 14
Dependent Claim
38 words
A hydraulic exercise device as recited in claim 1, wherein the mounting means whereto the chest exercise portion is releasably attached provides for vertical and horizontal pivoting at the connection thereto of each of the outstanding arm ends.
