Pull Up System And Bar Locking Fastener Therefor
A pull up system including a bar member a support assembly. The bar member is coupled to the support assembly and the support assembly is attachable to an outside surface. A bar locking fastener is likewise disclosed, as is a support assembly for a pull up system.
1 . A pull up system comprising:
a bar member having a first end and a second end opposite the first end, the bar member having an outer surface; and
a support assembly attachable to an outside surface, the support assembly including:
a first arm member and a second arm member, spaced apart from each other, and each having a proximal end and a distal end opposite the proximal end with the distal end spaced apart from the outside surface, at least one of the first arm member and the second arm member including:
a transverse opening, the transverse opening structurally configured to receive the bar member slidably therethrough with a locking opening positioned proximate thereto, and in communication therewith; and
a bar locking fastener having a flange nut with an upper portion and a lower flange, the upper portion having a perimeter which shape matingly engages the locking opening so as to preclude substantial rotation therebetween when the upper portion is inserted into the locking opening, with the lower flange being such that passage thereof through the locking opening is precluded when in the operable position between the locking opening and the transverse opening, and, a bolt being threadedly engaged with the flange nut, with a lower end surface extendable into the transverse opening,
whereupon positioning of the bar member through the transverse opening, the lower end surface of the bolt can be threadedly engaged with the flange nut to clamp the bar member to the arm member.
2 . The pull up system of claim 1 wherein the bar member has a substantially circular cross-sectional configuration.
3 . The pull up system of claim 2 wherein the bar member is a substantially elongated cylindrical member.
4 . The pull up system of claim 1 wherein the first arm member and the second arm member each include the transverse opening and the bar locking fastener.
5 . The pull up system of claim 4 wherein the transverse opening comprises a polygonal configuration.
6 . The pull up system of claim 5 wherein the upper portion of the flange nut comprises a polygonal configuration.
7 . The pull up system of claim 6 wherein the polygonal configuration of each of the transverse opening and the upper portion of the flange nut each comprise a hexagonal configuration.
8 . The pull up system of claim 6 wherein the lower flange comprises a substantially circular configuration.
9 . The pull up system of claim 1 wherein the flange nut is separable from the transverse opening so as to selectively permit coupling and decoupling of the same.
10 . The pull up system of claim 1 wherein the first arm member and the second arm member are substantially parallel to each other and spaced apart from each other a distance that corresponds to a distance that is less than a length of the bar member.
11 . A bar locking fastener for a pull up system comprising:
a flange nut insertable into a corresponding opening of an arm member of a support assembly, proximate a transverse opening; and
a bolt threadable through the flange nut and extendable into the transverse opening.
12 . The bar locking fastener of claim 11 wherein the flange nut includes an upper portion and a lower flange, the upper portion having a shape that limits rotation within the transverse opening.
13 . The bar locking fastener of claim 12 wherein the flange nut comprises a polygonal configuration.
14 . The bar locking fastener of claim 13 wherein the polygonal configuration comprises a hexagonal configuration.
15 . The bar locking fastener of claim 14 wherein the lower flange has a circular configuration.
16 . A support assembly for a pull up system comprising:
an arm member having:
a proximal end and a distal end, a first side and a second side opposite the second side, and a top surface and a bottom surface opposite the top surface so as to define an elongated member with a substantially rectangular cross-sectional configuration;
a transverse opening extending through the first side and the second side, the transverse opening structurally configured to have a bar member extendable through the transverse opening;
a locking opening extending through one of the top surface and the bottom surface and in communication with the transverse opening, the locking opening having a shape; and
a bar locking fastener having:
a flange nut, the flange nut having an upper portion and a lower flange, with the flange nut insertable through the transverse opening so as to extend the upper portion through the locking opening, with the lower flange sized so as to preclude passage thereof through the locking opening, and with the shape of the locking opening limiting rotation of the flange nut therein; and
a bolt having a shaft threadable through the flange nut so as to be extendable into the transverse opening, with the bolt having a lower end surface engageable with the bar member, upon insertion of the bar member through the transverse opening.
17 . The support assembly of claim 16 wherein the transverse opening comprises a generally circular opening.
18 . The support assembly of claim 17 wherein the transverse opening is positioned closer to the distal end than the proximal end of the arm member.
19 . The support assembly of claim 16 wherein the shape of the locking opening and the upper portion of the flange nut each comprise a polygonal configuration.
20 . The support assembly of claim 16 wherein the flange nut is separable from the arm member.
