The weights 123, for example, calibrated weights, sand bags, etc., at the first end 122a of the cable 122 counterbalance the user's weight at the second end 122b of the cable 122.
[0041] FIG. 12 illustrates a method for assembling an exercise apparatus 100. A clamping assembly 101 comprising claw members 102a and 102b, one or more adjustment plates 105, one or more pivot plates 106, and a weight bearing assembly 107 is provided 1201. The adjustment plates 105 are rigidly attached 1202 to a second surface 103b of the vertical web 103 of a first claw member 102a of the clamping assembly 101. The adjustment plates 105 extend outwardly and perpendicularly from the second surface 103b of the vertical web 103 of the first claw member 102a. The pivot plates 106 are rigidly attached 1203 to the second surface 103b of the vertical web 103 of the second claw member 102b of the clamping assembly 101. The pivot plates 106 extend outwardly and perpendicularly from the second surface 103b of the vertical web 103 of the second claw member 102b. The first end 108a of the leg member 108 of the weight bearing assembly 107 is pivotally connected 1204 in the space 106c defined between the pivot plates 106, for example, using a pivot sleeve 127a and a pivot sleeve cap screw 127c.

The second end 108c of the leg member 108 of the weight bearing assembly 107 is rigidly attached 1206 to the support frame 109. The gripping handles 110 are rigidly attached 1207 to the support frame 109. For example, the gripping bars 113 are rigidly attached to the ends 112a of the lateral arms 112 of the support frame 109. An elongated rod 114 can also be inserted into openings 112b and 112c defined on the ends 112a of the lateral arms 112 of the support frame 109 and disposed within the space 109a defined by the support frame 109. A pulley 117 is rigidly attached 1208 to the leg member 108 of the weight bearing assembly 107. A cable 122, for example, a cord, a rope, a thick metal wire, etc., is rollably attached 1209 to the pulley 117, where the first end 122a of the cable 122 bears one or more weights 123, and the second end 122b of the cable 122 is removably attachable to a user.
[0042] Consider an example where a user performs exercises using the exercise apparatus 100 disclosed herein. The exercise apparatus 100 is detachably attached, for example, by bolts 118, countersunk bolts, etc., to a support structure 128, for example, an I-beam of a ceiling. The user adjusts the position of the weight bearing assembly 107 to one of different heights by rotating the weight bearing assembly 107 about the pivoting axis 106b and selectively connecting the leg member 108 of the weight bearing assembly 107 to opposing apertures 105a of the adjustment plates 105 using the adjustment fastener 115. The position of the weight bearing assembly 107 is selected based on preferences of the user. The user attaches the first end 122a of the cable 122 disposed within the pulley 117 to one or more weights 123. The user then attaches the second end 122b of the cable 122 around the user's waist. The weights 123, for example, calibrated weights, sand bags, etc., at the first end 122a of the cable 122 counterbalance the user's weight at the second end 122b of the cable 122, thereby reducing work done by the user to perform pull up exercises. The user now holds the gripping handles 110 and pulls upwards against the force of gravity to perform pull up exercises.
[0043] The exercise apparatus 100 disclosed herein allows the user to perform the pull up exercises repeatedly in an uninhibited motion, where the user has adequate clearances in multiple directions. The exercise apparatus 100 disclosed herein also enables a beginner to complete a full range of motion with the assistance of the weights 123 that counterbalance the user's weight via the pulley 117 until the beginner is strong enough to perform the pull up exercises without assistance. Furthermore, seasoned athletes can use the weights 123 that counterbalance their weight via the pulley 117 to perform negative repetitions, when the athletes have pushed themselves past a point of exhaustion.
[0044] The foregoing examples have been provided merely for the purpose of explanation and are in no way to be construed as limiting of the present invention disclosed herein. While the invention has been described with reference to various embodiments, it is understood that the words, which have been used herein, are words of description and illustration, rather than words of limitation. Further, although the invention has been described herein with reference to particular means, materials and embodiments, the invention is not intended to be limited to the particulars disclosed herein; rather, the invention extends to all functionally equivalent structures, methods and uses, such as are within the scope of the appended claims. Those skilled in the art, having the benefit of the teachings of this specification, may effect numerous modifications thereto and changes may be made without departing from the scope and spirit of the invention in its aspects.
