Height adjustable pull-up bar apparatus

Abstract

A removably mountable, height adjustable pull-up bar allows the device to be rapidly mounted at a number of different heights to the pair of vertical support members. The pull-up bar interconnects a pair of brackets, the top end of each bracket containing a pin which slides into apertures on the sides of each vertical support member from a first direction while the bottom end of each bracket includes a U-shaped member which may be clamped around the front and/or sides of a vertical support member and secured thereto.

What is claimed is: 
     
         1 . A removably mountable pull-up bar apparatus for use with a pair of support structures, each structure having at least two apertures extending at least partially therethrough, the apparatus comprising:
 a pair of brackets, each bracket having a first end securable to one of the support structures from a first direction and second end mountable to one of the support structures from a second direction; and   a bar extending between and secured to the brackets.   
     
     
         2 . The apparatus of  claim 1  wherein the first end of each bracket has extending therefrom a projection shaped to be received within an aperture of one of the support structure. 
     
     
         3 . The apparatus of  claim 2  wherein the projection at the first end of each bracket and the aperture extending at least partially through each support structure have circular perimeter profiles. 
     
     
         4 . The apparatus of  claim 1  wherein the second end of each bracket defines a U-shaped member disposable about an exterior portion of one of the support structure. 
     
     
         5 . The apparatus of  claim 4  wherein each of the support structures has a plurality of apertures extending at least partially therethrough, and wherein the U-shaped member at the second end of each bracket further comprises a movable locking member secured thereto and at least partially insertable into one of the plurality of apertures of the support structures. 
     
     
         6 . The apparatus of  claim 5  wherein at least one of the movable locking members is securable to a support structure from a second direction. 
     
     
         7 . The apparatus of  claim 5  wherein the second direction is a direction which is one of the same as, opposite to, or perpendicular to, the first direction. 
     
     
         8 . The apparatus of  claim 1  wherein the bar extends along an axis parallel with the first direction. 
     
     
         9 . The apparatus of  claim 6  wherein the bar comprises a hollow tube of rigid material. 
     
     
         10 . The apparatus of  claim 6  wherein the bar comprises a solid cylindrical body of rigid material. 
     
     
         11 . The apparatus of  claim 6  wherein the second direction is a direction that is the same as the first direction. 
     
     
         12 . The apparatus of  claim 6  wherein the second direction that is a direction opposite to the first direction. 
     
     
         13 . A method for mounting a pull-up bar apparatus to pair of support structures each structure, the method comprising:
 A) providing a removably mountable pull-up bar apparatus comprising a bar extending between and secured to a pair of brackets, each bracket having a first end pivotally securable to one of the support structures and second end mountable to one of the support structures;   B) pivotally mounting the first end of each bracket to one of the support structures from a first direction; and   C) mounting the second end of at least one of brackets to one of the support structures from a second direction.   
     
     
         14 . The method of  claim 13  wherein the second direction is a direction opposite the first direction. 
     
     
         15 . The method of  claim 13  wherein the second direction is a direction parallel to the first direction. 
     
     
         16 . The method of  claim 13  wherein the second direction is a direction perpendicular to the first direction. 
     
     
         17 . An article of manufacture comprising:
 a pair of brackets, each bracket comprising:
 i) a body member extending between first and second ends thereof; 
 ii) a projection extending outwardly from the first end of the body member in a first direction, the projection shaped to be received within an aperture on a support structure, and 
 iii) an aperture extending through a second end of the body member, the aperture shaped to retain a movable locking member therein; and 
   a bar extending between and secured to the pair of brackets.   
     
     
         18 . The article of manufacture of  claim 17  wherein at least one of the projections has substantially cylindrical shape. 
     
     
         19 . The article of manufacture of  claim 17  wherein at least one of the movable locking members is securable to the support structure from second direction which is one of the same as, opposite to, or perpendicular to, the first direction. 
     
     
         20 . The article of manufacture of  claim 17  wherein at least one of the movable locking members comprises one of a screw and a pop-pin.
