Abstract
Abstract An adjustable weight lifting device including an angled longitudinal bar fitted with an arm brace at its proximal end, and a stop at its distal end. On the longitudinal bar between the arm brace and the longitudinal bar's angle is a slidably mounted crossbar which the user grasps with his hands. Adjustable handles may be placed on the crossbar to provide different exercises for the arm muscles. A slidable carriage assembly to receive supplemental weights is mounted on the longitudinal bar between its angle and its distal end. The user achieves variety in his exercise by adjusting the crossbar, the handles and the carriage assembly, and by adding supplemental weights.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
195 words
An exercise apparatus for wrists and arms comprising: (a) a generally longitudinal angled bar said angle located proximate said bar's midpoint; (b) an elongated arm brace of a length sufficient to span the distance between a user's outwardly extended forearms, said brace mounted perpendicularly on and to said longitudinal bar's proximal end at said arm brace's midpoint; (c) a transverse crossbar slidably mounted on said longitudinal bar parallel to said arm brace and between said proximal end of said longitudinal bar and said bar's angle, said crossbar adapted to receive handles; (d) a carriage assembly slidably mounted on said longitudinal bar between said longitudinal bar's angle and said distal bar end, said assembly adapted to receive supplemental weights; (e) two adjustable, mushroom-shaped handles, each handle including: (i) a stem; (ii) a generally flat circular head on one stem end, said head having a stem-aligned aperture and at least one radial aperture; and, (iii) a handle locking assembly adapted slidably and rotatably to circumscribe said crossbar, said lock including two pins intended to mate with said apertures of part (ii) to adjustably lock said handle in a multitude of radial positions, one position at a time.
Claim 2
Dependent Claim
195 words
An exercise apparatus for wrists and arms comprising: (a) a generally longitudinal angled bar said angle located proximate said bar's midpoint; (b) an elongated arm brace of a length sufficient to span the distance between a user's outwardly extended forearms, said brace mounted perpendicularly on and to said longitudinal bar's proximal end at said arm brace's midpoint; (c) a transverse crossbar slidably mounted on said longitudinal bar parallel to said arm brace and between said proximal end of said longitudinal bar and said bar's angle, said crossbar adapted to receive handles; (d) a carriage assembly slidably mounted on said longitudinal bar between said longitudinal bar's angle and said distal bar end, said assembly adapted to receive supplemental weights; (e) two adjustable, mushroom-shaped handles, each handle including: (i) a stem; (ii) a generally flat circular head on one stem end, said head having a stem-aligned aperture and at least one radial aperture; and, (iii) a handle locking assembly adapted slidably and rotatably to circumscribe said crossbar, said lock including two pins intended to mate with said apertures of part (ii) to adjustably lock said handle in a multitude of radial positions, one position at a time.
Claim 3
Dependent Claim
129 words
The exercise apparatus according to claim 1 wherein said carriage assembly comprises: (a') a carriage sleeve slidably mounted on said longitudinal bar, said sleeve including a safety ridge at one end; (b') a slidable collar parametrically mounted around said sleeve; (c') collar locking means to secure said collar to said sleeve; (d') a backing plate circumscribing said sleeve proximate said sleeve's other end; (e') carriage locking means to hold said carriage in place on said longitudinal bar; and, (f') stop means to prevent said carriage assembly from sliding into undesired positions, so that when one or more supplemental weights are mounted on said sleeve between said collar and said backing plate, said backing plate aligns said weights and said collar locking means holds said collar fast against said weights.
Claim 4
Dependent Claim
25 words
The exercise apparatus according to claim 2 wherein said collar locking means is a bolt and said collar includes an aperture to receive said bolt.
Claim 5
Dependent Claim
25 words
The exercise apparatus according to claim 2 wherein said carriage locking means is a bolt and said sleeve includes an aperture to receive said bolt.
Claim 6
Dependent Claim
90 words
The exercise apparatus according to claim 1 wherein said handle locking assembly comprises, additionally, a U-shaped bolt, each bolt end forming one of said pins, a first leg including threads to receive a nut, said other leg including a stop to align said pressplate against said crossbar, said bolt having circumferential markings to aid in placement of said handle; a press plate having two apertures through which each of said U-bolt legs pass, said press plate stabilizing said handle head; and a nut adapted to fit said threaded bolt end.
Claim 7
Dependent Claim
38 words
The exercise apparatus according to claim 1 wherein said longitudinal bar is a rod having a flattened area along at least part of its length, said flattened area preventing said crossbar from rotating around said longitudinal bar's circumference.
Claim 8
Dependent Claim
16 words
The exercise apparatus according to claim 3 wherein one of said carriage stops is a knob.
Claim 9
Dependent Claim
23 words
The exercise apparatus according to claim 1 wherein said arm brace includes circumferential padding to protect a user's arms and prevent their slippage.
Claim 10
Dependent Claim
31 words
The exercise apparatus according to claim 1 wherein said transverse crossbar is marked longitudinally and circumferentially in evenly spaced positions along said crossbar's length to evenly align said handle locking assembly.
Claim 11
Dependent Claim
18 words
The exercise apparatus according to claim 1 including, additionally, a reinforcing brace spanning said longitudinal bar's obtuse angle.
Claim 12
Dependent Claim
16 words
The exercise apparatus according to claim 1 wherein said arm brace includes caps on its ends.
Claim 13
Dependent Claim
14 words
The exercise apparatus according to claim 1 wherein said arm brace is a rod.
Claim 14
Dependent Claim
24 words
The exercise apparatus according to claim 1 wherein said transverse crossbar has a slot at generally its midpoint sized to receive said longitudinal bar.
Claim 15
Dependent Claim
28 words
The exercise apparatus according to claim 1 wherein said transverse crossbar includes a locking bolt to secure said crossbar in position and an aperture to receive said bolt.
Claim 16
Dependent Claim
12 words
The exercise apparatus according to claim 1 wherein said crossbar is cylindrical.
Claim 17
Dependent Claim
20 words
The exercise apparatus according to claim 1 including, additionally, a hand stop on said handle's stem end opposite said head.
Claim 18
Dependent Claim
13 words
The hand stop according to claim 16 wherein said stop is a knob.
