Extending Pull-Up Bar

Abstract

An exercise apparatus for pull ups has two L-shaped tubes, each having a first segment and a second segment. The L-shaped tubes are mounted in parallel planes to a mounting bracket, a stabilizer bar, and a pull up bar. The first segment of the L-shaped tube is a first outer tube containing a plurality of telescoping tubes within the outer tube. The apparatus may be lowered or raised by removing the pin from the pin-holes of the plurality of telescoping tubes, sliding at least one inner telescoping tube out from, or into, an outer telescoping tube, and then inserting the pin through the through-hole of the telescoping tubes to lock the adjusted height in place.

What is claimed is: 
     
         1 . An exercise device comprising:
 at least one L-shaped tube having a first, length-adjustable, segment and a generally perpendicular second segment;   the L-shaped tube rigidly fixed to a mounting bracket, a stabilizer bar, and a pull up bar; and   the mounting bracket, stabilizer bar, and pull-up bar extending generally parallel to each other, and generally perpendicular to the L-shaped tube.   
     
     
         2 . The exercise device of  claim 1 , further comprising:
 at least two of the L-shaped tubes mounted in parallel planes, wherein the stabilizer bar and pull-up bar extend between the two parallel L-shaped tubes.   
     
     
         3 . The exercise device of  claim 1 , wherein the first segment includes an outermost telescoping tube, and an innermost telescoping tube slidably attached to the outermost telescoping tube. 
     
     
         4 . The exercise device of  claim 3 , wherein:
 the mounting bracket is attached to the outermost telescoping tube; and   the stabilizer bar is mounted to the innermost telescoping tube.   
     
     
         5 . The exercise device of  claim 3 , further comprising:
 a through-hole for receiving a pin on the distal end of the outermost telescoping tube; and   a through-hole on both the distal end and the proximal end of the innermost telescoping tubes.   
     
     
         6 . The exercise device of  claim 3 , wherein:
 the first segment and the second segment are connected by a curved cuff;   a first end of the curved cuff is rigidly fixed to the distal end of the innermost telescoping tube; and   a second end of the curved cuff is rigidly fixed to one end of the second segment.   
     
     
         7 . The exercise device of  claim 3 , further comprising:
 a plurality of telescoping tubes slidably attached to the outermost telescoping tube and the innermost telescoping tube.   
     
     
         8 . The exercise device of  claim 7 , wherein:
 each telescoping tube is lockable to at least one adjacent tube at the extended position.   
     
     
         9 . The exercise device of  claim 7 , further comprising a through-hole for receiving a pin on each distal end and each proximal end of each of the plurality of telescoping tubes. 
     
     
         10 . The exercise device of  claim 1 , wherein:
 the mounting bracket is attached at the proximal end of the first segment, and the stabilizer bar is attached to the distal end of the first segment.   
     
     
         11 . The exercise device of  claim 1 , further comprising a pin, wherein one end of the pin is attached to the stabilizer bar with a stretchy cord. 
     
     
         12 . The exercise device of  claim 1 , wherein the first segment and the second segment are connected by a connector. 
     
     
         13 . The exercise device of  claim 1 , wherein the pull up bar is attached to the second segment of the L-tube. 
     
     
         14 . The exercise device of  claim 13 , wherein the pull up bar is set partially back from the distal end of the second segment, to create a free end at distal end of the second segment. 
     
     
         15 . The exercise device of  claim 1 , further comprising at least one accessory ring attached to at least one of the pull-up bar and the stability bar. 
     
     
         16 . The exercise device of  claim 1 , further comprising a plurality of grips at least partially encasing the pull up bar, the stabilizer bar, and the second segment. 
     
     
         17 . The exercise device of  claim 16 , wherein the grip is a flexible material, and is one of:
 rubberized, texturized, or soft touch.   
     
     
         18 . An exercise device comprising:
 at least two L-shaped tubes, each having a vertically extending first segment and a generally perpendicular outwardly extending second segment;   a pull up bar and a stabilizer bar extending generally parallel to each other between the two L-shaped tubes, and generally perpendicular to the L-shaped tubes;   the first segments include an outermost telescoping tube, and an innermost telescoping tube slidably attached to the outermost telescoping tube; and   a mounting bracket attached to at least one of the L-shaped tubes;   the pull up bar being attached to the second segment of the L-tube; and   the pull up bar being set partially back from the distal end of the second segment, to create a free end at distal end of the second segment.   
     
     
         19 . The exercise device of  claim 20 , further comprising a plurality of grips at least partially encasing the pull up bar, the stabilizer bar and the free end of the second segment. 
     
     
         20 . The exercise device of  claim 20 , further comprising a releasable lock for releasably locking the innermost telescoping tube with respect to the outermost telescoping tube.
