Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
170 words
A physical exercise device comprising: a base having a bracket at one end; a seat member detachably engaged with said base; a supporting frame having two rods extending out therefrom in opposite directions and having one end detachably engaged with said bracket; a handling means having a connecting plate, pivotally engaged to the other end of said supporting frame, two handle bars, two sleeves sleeved on said rods respectively, each sleeve being connected to said connecting plate at one end and having an ear element at the other end for pivotally connecting to said respective handle bar, so that said handle bars can be rotated in a horizontal direction, and two plastic resistors respectively sleeved on to the connective portions between said handle bars and said sleeves for resisting the movement of said handle bars; and a hydraulic cylinder comprised of a piston and a piston rod having the piston end connected to said supporting frame and the piston rod detachable connected to said connecting plate for producing hydraulic resistance.
Claim 2
Dependent Claim
170 words
A physical exercise device comprising: a base having a bracket at one end; a seat member detachably engaged with said base; a supporting frame having two rods extending out therefrom in opposite directions and having one end detachably engaged with said bracket; a handling means having a connecting plate, pivotally engaged to the other end of said supporting frame, two handle bars, two sleeves sleeved on said rods respectively, each sleeve being connected to said connecting plate at one end and having an ear element at the other end for pivotally connecting to said respective handle bar, so that said handle bars can be rotated in a horizontal direction, and two plastic resistors respectively sleeved on to the connective portions between said handle bars and said sleeves for resisting the movement of said handle bars; and a hydraulic cylinder comprised of a piston and a piston rod having the piston end connected to said supporting frame and the piston rod detachable connected to said connecting plate for producing hydraulic resistance.
Claim 3
Dependent Claim
42 words
A physical exercise device as claimed in claim 1, wherein said connecting plate has a plurality of holes for the piston rod of said hydraulic cylinder to selectively connect to said connecting plate through one hole in order to provide selective resistance.
Claim 4
Dependent Claim
99 words
A physical exercise device as claimed in claim 2, wherein said bracket has a front plate and two side plates, and said physical exercise device further comprises two reinforced plates respectively secured on said side plates of said bracket with a portion extending out from two sides of said front plate for said supporting frame to pivotally connect between said reinforced plates and adjacent to the front surface of said front plate, so that said supporting frame only can rotate between said base and said front surface when the engagement between said bracket and said supporting frame is detached.
Claim 5
Dependent Claim
38 words
A physical exercise device as claimed in claim 3, wherein said supporting frame is a rectangular frame which has a centrally hollow portion, with said hydraulic cylinder is mounted in said centrally hollow portion at its one end.
Claim 6
Dependent Claim
100 words
A physical exercise device as claimed in claim 4, wherein on said front plate of said bracket an aperture is provided, and said supporting frame is engaged to said front plate by a handled screw screwing into a nut behind said front plate through said centrally hollow portion of said supporting frame and said aperture with the handle of said handled screw abutting against said supporting frame, so that said supporting frame is firmly engaged with said base in an upright position, and so that said handle bars can be upwardly and downwardly moved in relation to said supporting frame.
Claim 7
Dependent Claim
18 words
A physical exercise device as claimed in claim 5, wherein said hydraulic cylinder inclines toward said seat member.
Claim 8
Dependent Claim
26 words
A physical exercise device as claimed in claim 6, wherein said physical exercise device further comprises a pair of pedals pivotally connected on said base respectively.
Claim 9
Dependent Claim
37 words
A physical exercise device as claimed in claim 4, wherein said supporting frame with said handling means are arranged between said base and said seat member, so that said handling means can be moved in rowing motion.
Claim 10
Dependent Claim
21 words
A physical exercise device as claimed in claim 8, wherein said hydraulic cylinder inclines toward the bottom of said seat member.
Claim 11
Dependent Claim
26 words
A physical exercise device as claimed in claim 9, wherein said physical exercise device further comprises a pair of pedals pivotally connected on said base respectively.
