Adaptable bar

Abstract

An adaptable bar with means at the ends thereof for securing same between two opposite surfaces is provided that includes a variable-angle attachment unit with a movable double spider that allows the joining angle between the variable-angle attachment unit and the bar to be changed and fixed in two axes of space, the length of the bar being adjustable by means of inner tubes provided with threaded units. The attachment unit includes a plate for securing to a wall, which plate is secured independently and on which the bar fits. The movable double spider includes a cardan joint to which is joined, on one side, respective lugs of a connection base with a pin that provides an articulated joint in a first axis of the space, and on the other side, a connector with another pin perpendicular to the first that provides another articulated joint in a second axis of the space.

1 . An adaptable bar which, being one of those intended for doing pull-ups and made up of a bar ( 1 ) with wall securing means at the two ends thereof for securing same between two opposing surfaces, is characterised in that it comprises, on at least one of said ends, a variable-angle attachment unit ( 2 ) which includes a movable double spider ( 21 ) that allows the joining angle between said variable-angle attachment unit ( 2 ) and the bar ( 1 ) itself to be changed and fixed in two axes of the space. 
     
     
         2 . The adaptable bar, according to  claim 1 , characterised in that it has at both ends a variable-angle attachment unit ( 2 ) with a movable double spider ( 21 ) that allows the joining angle thereof with the bar ( 1 ) itself to be changed and fixed in two axes of the space. 
     
     
         3 . The adaptable bar, according to  claim 1 , characterised in that the variable-angle attachment unit ( 2 ) comprises a plate for securing to the wall ( 22 ) which is secured independently, whereon the bar ( 1 ) fits. 
     
     
         4 . The adaptable bar, according to  claim 3 , characterised in that the bar ( 1 ) fits into the securing plate ( 22 ) through a connection base ( 24 ) which can be inserted into a guide ( 25 ) envisaged for this purpose in said securing plate ( 22 ). 
     
     
         5 . The adaptable bar, according to  claim 4 , characterised in that the movable double spider ( 21 ) comprises a cardan joint ( 26 ) to which is joined, on one side, respective lugs of the connection base ( 24 ) with a pin ( 27 ) that provides an articulated joint in a first axis of the space, and on the other side, a connector ( 28 ) with another pin ( 27 ) perpendicular to the first that provides another articulated joint in a second axis of the space, this connector ( 28 ) being joined, in turn, to the bar ( 1 ) on the opposite side thereof. 
     
     
         6 . The adaptable bar, according to  claim 1 , characterised in that the variable-angle attachment unit ( 2 ) is covered and protected by an ornamental bellows ( 29 ) which covers all the elements thereof. 
     
     
         7 . The adaptable bar, according to  claim 1 , characterised in that it further comprises means for adjusting the length of the bar ( 1 ). 
     
     
         8 . The adaptable bar, according to  claim 7 , characterised in that, as means for adjusting the length of the bar ( 1 ), it comprises two inner tubes ( 11 ), joined at one end to the respective securing ends of the bar, and at the opposite end to a central outer tube ( 12 ), by means of respective threaded units ( 13 ), one right-handed and the other left-handed, which, in turn, comprise a conical screw ( 14 ) integral to the inner tube ( 11 ) which threads into a nut ( 15 ) integral to the outer tube ( 12 ). 
     
     
         9 . The adaptable bar, according to  claim 2 , characterised in that the variable-angle attachment unit ( 2 ) comprises a plate for securing to the wall ( 22 ) which is secured independently, whereon the bar ( 1 ) fits. 
     
     
         10 . The adaptable bar, according to  claim 2 , characterised in that the variable-angle attachment unit ( 2 ) is covered and protected by an ornamental bellows ( 29 ) which covers all the elements thereof. 
     
     
         11 . The adaptable bar, according to  claim 3 , characterised in that the variable-angle attachment unit ( 2 ) is covered and protected by an ornamental bellows ( 29 ) which covers all the elements thereof. 
     
     
         12 . The adaptable bar, according to  claim 4 , characterised in that the variable-angle attachment unit ( 2 ) is covered and protected by an ornamental bellows ( 29 ) which covers all the elements thereof. 
     
     
         13 . The adaptable bar, according to  claim 5 , characterised in that the variable-angle attachment unit ( 2 ) is covered and protected by an ornamental bellows ( 29 ) which covers all the elements thereof. 
     
     
         14 . The adaptable bar, according to  claim 2 , characterised in that it further comprises means for adjusting the length of the bar ( 1 ). 
     
     
         15 . The adaptable bar, according to  claim 3 , characterised in that it further comprises means for adjusting the length of the bar ( 1 ). 
     
     
         16 . The adaptable bar, according to  claim 4 , characterised in that it further comprises means for adjusting the length of the bar ( 1 ). 
     
     
         17 . The adaptable bar, according to  claim 5 , characterised in that it further comprises means for adjusting the length of the bar ( 1 ).
