Telescoping Door Mount Exercise Bar

Abstract

A door-frame mounted exercise bar having two ends, each covered by a frictional, compressible substance, wherein said exercise bar is lengthwise adjustable by means of a ratchet operated strap, thus allowing the user to securely fit the exercise bar into a door-frame. The exercise bar has attachment points for elastic straps and other devices and mounting posts on its top surface. A stabilizer/attachment bar is provided having mounting sleeves aligned to coincide with, and attach to, the mounting posts on top of the exercise bar. These mounting sleeves also serve as attachment points for handles, exercise bars, and other accessories. The stabilizer/attachment bar is lengthwise adjustable such that the ends of the bar may be fixably insinuated behind the door stop molding found on most doors. When thus deployed, the stabilizer/attachment bar prevents the exercise bar from rotating when used.

What is claimed is: 
     
         1 . A telescoping door frame mount exercise bar comprising:
 a) a central outermost telescoping bar, a left innermost telescoping bar, and a right innermost telescoping bar,   b) wherein said central outermost telescoping bar is disposed outside of said left innermost telescoping bar and said right innermost telescoping bar,   c) wherein the proximal ends of said left innermost telescoping bar and said right innermost telescoping bar are inserted into opposite ends said central outermost telescoping bar and telescopically slidably displaceable with respect to said central outermost telescoping bar,   d) wherein a plurality of elastic band attachment points are attached at different positions along the length of said central outermost telescoping bar,   e) wherein said elastic band attachment points comprise a selection from a group consisting of:
 a) a rectangular ring, and 
 b) a clip, and 
 c) a hook, 
   f) wherein a plurality of attachment posts are perpendicularly attached to the top surface of said central outermost telescoping bar at different positions along the length of said central outermost telescoping bar,   g) wherein the distal end of said left innermost telescoping bar is attached to a left end plate, said left end plate having an outward-facing frictional, compressible pad and the distal end of said right innermost telescoping bar is attached to a right end plate, said right end plate having an outward-facing frictional, compressible pad,   h) wherein said left innermost telescoping bar is provided with a plurality of holes at different positions along its length, said central outermost telescoping bar being selectively fastenable to said holes at different hole positions along said left innermost telescoping bar to provide an initial rough length adjustment to a dimension less than the width of a door frame,   i) wherein a variable length adjusting means is attached at its first end to the distal right of said central outermost telescoping bar by means of a bolt or other anchoring means and at the other end to the proximal end of said right innermost telescoping bar by means of a bolt or other anchoring means protruding though a linear slot in said central outermost telescoping bar, and   j) wherein said variable length adjusting means comprises a selection from a group consisting of:
 a) a ratchet adjustable strap, and 
 b) a ratchet adjustable cable, and 
 c) a ratchet adjustable rope, and 
 d) a ratchet adjustable rod. 
   
     
     
         2 . A telescoping door mount exercise bar as in  claim 1 , further comprising:
 a) a vertical linear groove or depression formed in the outward-facing face of said frictional, compressible outer pad attached to said left end plate, and   b) a vertical linear groove or depression formed in the outward-facing face of said frictional, compressible outer pad attached to said right end plate.   
     
     
         3 . A telescoping door mount exercise bar as in  claim 2 , further comprising:
 a) a horizontal stabilizer tube, a left extensible innermost outrigger tube, and a right extensible innermost outrigger tube,   b) wherein said horizontal stabilizer tube is disposed outside of said left extensible outrigger tube and said right extensible outrigger tube,   c) wherein the proximal ends of said left extensible outrigger tube and said right extensible outrigger tube are inserted into opposite ends of said horizontal stabilizer tube and telescopically slidably displaceable with respect to said horizontal stabilizer tube,   d) wherein at least one arresting means capable of penetrating into the central cavity of said horizontal stabilizer tube is provided at the left end of said horizontal stabilizer tube such that said arresting means fixably prohibits the slidable displacement of said left extensible outrigger tube with respect to said horizontal stabilizer tube at a user selectable position, and, at least one arresting means capable of penetrating into the central cavity of said horizontal stabilizer tube is provided at the right end of said horizontal stabilizer tube such that said arresting means fixably prohibits the slidable displacement of said right extensible outrigger tube with respect to said horizontal telescoping stabilizer tube at a user selectable position,   e) wherein said arresting means comprise a selection from a group consisting of:
 a) a thumb screw, and 
 b) a screw, and 
 c) a pin, and 
 d) a cam, 
   f) wherein a plurality of mounting sleeves are perpendicularly attached to the front surface of said horizontal stabilizer tube at different positions along the length of said outermost telescoping stabilizer tube,   g) wherein at least one locating means capable of penetrating into the central cavity of said mounting sleeves is provided at the top end of said mounting sleeves,   h) wherein said locating means comprise a selection from a group consisting of:
 a. a rivet, and 
 b. a screw, and 
 c. a pin, 
   i) wherein the distal end of said left extensible outrigger tube is covered by a left protective cap, and, the distal end of said right extensible outrigger tube is covered by a right protective cap,   j) wherein said protective caps are composed of a substance selected from a group consisting of:
 a) rubber, and 
 b) plastic, and 
 c) leather, and 
 d) vinyl. 
   
     
     
         4 . A telescoping door mount exercise bar as in  claim 3 , further comprising:
 a) One or more exercise attachments, slidably insertable into said mounting sleeves, comprising a selection from a group consisting of:
 a) handles, and 
 b) a pull-up bar, and 
 c) a dips-bar, 
   b) wherein exercise attachments are notched so as to engage said locating means penetrating into said mounting sleeves when slidably inserted into said mounting sleeves.
