Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority from U.S. Pat. App. Ser.
No. 62/544,954 filed Aug. 14, 2017, entitled "Pull Up System and
Bar Locking Fastener Therefor", the entire disclosure of which is
hereby incorporated by reference in its entirety.
BACKGROUND OF THE DISCLOSURE
1. Field of the Disclosure
[0002] The disclosure relates in general to exercise equipment, and
more particularly, to a pull up system as well as to a bar locking
fastener utilized with the pull up system.
2. Background Art
[0003] The performance of body weight exercises has long been the
mainstay of many athletes. One of these body weight exercises is
the pull up (also sometimes known as a chin up). Such body weight
exercises are known and equipment for such exercises has been
known.
[0004] Typically, such equipment comprises a bar (generally of a
substantially uniform round cross-sectional configuration). Such
bars are coupled to support arms, support members, or other
structures which essentially suspend the bar therebetween. In many
instances, the bar is welded to the support structures. As such,
the bar is essentially permanently coupled to the support
structures.
[0005] In other configurations, the bar may be releasably coupled
to the support structures. In some such configurations, the
supports may include a bar with openings configured to slidably
receive a bar member. Typically, the bar member is maintained in
the desired position by a clamp bolt that can sandwich the bar
member against the opening. Typically, such a clamp bolt relies
upon an opening transverse to the bar opening, which opening has a
threaded nut welded thereover. The bolt can be threaded through the
fastener and the opening and into contact with the bar. One such
configuration is shown in the P3 Pull-Up system offered by Rogue
Fitness of Columbus, Ohio. Problematically, such a construction is
typically time consuming and requires proper alignment of the nut
and the opening.
[0006] Additionally, in many instances the support arms comprise
relatively complex systems of components that are welded together.
Again, such a system is time consuming and costly to manufacture
due to the different components and the welding that is required to
join the different components.
SUMMARY OF THE DISCLOSURE
[0007] The disclosure is directed to a pull up system comprising a
bar member and a support assembly. The bar member is coupled to the
support assembly. The support assembly is attachable to an outside
surface.
[0008] In an aspect of the disclosure, the disclosure is directed
to a pull up system comprising a bar member, and a support
assembly. The bar member has a first end and a second end opposite
the first end. The bar member has an outer surface. The support
assembly is attachable to an outside surface. The support assembly
includes a first arm member and a second arm member which are
spaced apart from each other. Each has 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 includes a transverse opening and a bar locking
fastener. The transverse opening is structurally configured to
receive the bar member slidably therethrough with a locking opening
positioned proximate thereto, and in communication therewith.
[0009] The bar locking fastener has a flange nut with an upper
portion and a lower flange. The upper portion has 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. The lower flange is configured
such that passage thereof through the locking opening is precluded
when in the operable position between the locking opening and the
transverse opening. A bolt is threadedly engaged with the flange
nut, with a lower end surface extendable into the transverse
opening. Upon 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.
[0010] In some configurations, the bar member has a substantially
circular cross-sectional configuration.
[0011] In some such configurations, the bar member is a
substantially elongated cylindrical member.
[0012] In some configurations, the first arm member and the second
arm member each include the transverse opening and the bar locking
fastener.

polygonal configuration.
[0014] In some such configurations, the upper portion of the flange
nut comprises a polygonal configuration.
[0015] In some such configurations, the polygonal configuration of
each of the transverse opening and the upper portion of the flange
nut each comprise a hexagonal configuration.
[0016] In some configurations, the lower flange comprises a
substantially circular configuration.
[0017] In some configurations, the flange nut is separable from the
transverse opening so as to selectively permit coupling and
decoupling of the same.
[0018] In some configurations, 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.
[0019] In another aspect of the disclosure, the disclosure is
directed to a bar locking fastener for a pull up system that
includes a flange nut and a bolt. The flange nut is insertable into
a corresponding opening of an arm member of a support assembly,
proximate a transverse opening. The bolt is threadable through the
flange nut and extendable into the transverse opening.
[0020] In some configurations, the flange nut includes an upper
portion and a lower flange. The upper portion has a shape that
limits rotation within the transverse opening.
[0021] In some configurations, the flange nut comprises a polygonal
configuration.
[0022] In some configurations, the polygonal configuration
comprises a hexagonal configuration.
[0023] In some configurations, the lower flange has a circular
configuration.
[0024] In another aspect of the disclosure, the disclosure is
directed to a support assembly for a pull up system. The system
comprises an arm member and a bar locking fastener. The arm member

generally circular opening.
[0027] In some configurations, the transverse opening is positioned
closer to the distal end than the proximal end of the arm
member.
[0028] In some configurations, the shape of the locking opening and
the upper portion of the flange nut each comprise a polygonal
configuration.
[0029] In some configurations, the flange nut is separable from the
arm member.

DETAILED DESCRIPTION OF THE DISCLOSURE
[0036] While this disclosure is susceptible of embodiment in many
different forms, there is shown in the drawings and described
herein in detail a specific embodiment(s) with the understanding
that the present disclosure is to be considered as an
exemplification and is not intended to be limited to the
embodiment(s) illustrated.
[0037] It will be understood that like or analogous elements and/or
components, referred to herein, may be identified throughout the
drawings by like reference characters. In addition, it will be
understood that the drawings are merely schematic representations
of the invention, and some of the components may have been
distorted from actual scale for purposes of pictorial clarity.
[0038] Referring now to the drawings and in particular to FIG. 1,
the pull up system is shown generally at 10. The pull up system is
typically mounted to a wall or to a ceiling spaced apart from the
ground so that a user can utilize the pull up system to perform
exercises such as pull ups, chin-ups, muscle ups, hangs, among
others. Indeed, the pull up system is not limited to any particular
exercise nor is the same limited to attachment to any particular
outside device. In some configurations, the pull up system, for
example, may be configured to be free standing, and mounted to a
stand of various types. In other configurations, the pull up system
may be releasably mounted to an outside structure, such as a tree
or the like.
[0039] In the configuration shown, the pull up system comprise bar
member 12 and a plurality of support assemblies, such as support
assembly 14. It is to be understood the pull up system 10 is
manufactured with a substantially strong metallic material such
that it allows for supporting an adult body within motion. Further,
it is to be understood the pull up system 10 includes two support
assemblies 14 be positioned parallel in reference to one another
along a planar wall. Distance between the two support assemblies 14
is, in many instances, the length of the bar member 12. A number of
different assemblies of the bar member 12 and support assembly 14
are contemplated. For example, a contemplated configuration
designed outside of the scope of the figures is an extended bar
member 12 that is secured through three support assemblies 14 that
are all parallel and equal in reference to one another. Further,
the bar member 12 in the contemplated assembly is perpendicular in
reference to all previously described support assemblies and equal
secured to each.
[0040] As illustrated in FIG. 1, bar member 12 comprises first end
16, second end 18, and outer surface 19. The length of the bar
member 12 is defined by the distance between first end 16 and
second end 18. In the configuration shown, the bar member 12 is
substantially of a uniform circular cross-sectional construction
and include an inner hollow structure or cavity such that the bar
member is has a pipe-like configuration. It will be understood that
the first end and the second end may be capped with a cap or other
covering to preclude ingress into the inner hollow structure. In
other configurations, the ends may remain open and access to the
inner cavity is permitted. In other configurations, it is
Contemplated that bar member 12 may define non-circular
cross-sectional shapes, such as oval, square, polygonal, arbitrary
or other shapes. It will further be understood that the
cross-sectional configuration may change along the length thereof
between the first and second ends thereof.
[0041] Additionally, while a generally hollow bar 12 is shown, it
will be understood that the bar 12 may be solid, or may include
reinforcing ribs or other structures that extend within the hollow
cavity (wherein the bar can be formed from an extrusion or the
like, for example). It will be understood that the bar is formed,
preferably from a metal member, and may have a finish or a coating
thereon. For example, the metal member may be anodized, painted,
powder coated, dipped, or otherwise finished. Additionally, surface
finishes such as knurling, for example, are also contemplated.
[0042] As illustrated in FIGS. 1, 2, and 3, support assembly 14
comprises an arm member 20, wall coupling member 22, and bar
locking fastener 24. The arm member 20 includes proximal end 30 and
distal end 31 which defines the length of the arm member 20. In the
configuration shown, the arm member 20 has a generally rectangular
cross-sectional configuration (which is again hollow, defining a
cavity), and includes first side 32, second side 33, top surface 34
and bottom surface 35 on the vertical plane. It will be understood
that a number of different configurations are contemplated for the
arm member 20 for example, in reference to location of coupling,
size differences, and shapes of both members. Additionally, it will
be understood that while the arm members are shown to be identical,
variations between arm members is contemplated.
[0043] The arm member 20 further comprises at least one transverse
opening 36 aligned axially through the first side 32 and second
side 33. Transverse openings 36 are generally of equal or greater
dimension relative to the bar member 12 so that the bar member can
be slidably extended through the openings. A plurality of
transverse openings 36 may be present along the arm member 20.
Further, transverse openings are separated by a contemplated
distance along the length of the arm member, between the proximal
end 30 to the distal end 31. In the configuration shown, two
openings are positioned in a spaced apart orientation with the
first of the openings being positioned proximate the distal end,
and the second being spaced therefrom toward the proximal end. In
the configuration shown, both openings remain closer to the distal
end than the proximal end. Additionally, both openings are
substantially identical in configuration, although the same is not
required.
[0044] With additional reference to FIG. 4, in addition to FIGS. 1
through 3, located along with the transverse openings 36 are
corresponding locking openings 37. In particular, the locking
openings extend through the top surface 34 of the arm member 20
just above the openings. More specifically, the locking openings 37
are located along just above of the center of the transverse
openings 36. That is, for each transverse opening 36 positioned
along the arm member 20, a locking opening 37 is present just above
through the top surface. Locking openings 37 are shaped in a
hexagonal manner with all sides substantially equal in size in
relation to one another, in the configuration shown, to
substantially match a hexagonal fastener. It is contemplated that
the opening may have a shape different than the hexagonal shape,
wherein the shape precludes rotation of a structure positioned
therein, which has the same shape. As such, an opening other than
circular is contemplated. That is, the opening is preferably keyed
in some manner such that positive engagement (without relative
rotation) can be achieved (as will be explained below).
Additionally, while the locking opening is shown to be in the top
surface, the opening can likewise be present in the bottom surface,
or in both surfaces. In some configurations, additional surfaces
(which are outside of the transverse opening but close thereto) may
likewise define the locking openings.
[0045] The wall coupling member 22, as is shown in FIG. 1 comprises
first gusset bracket 50 and second gusset bracket 60. The two
gusset brackets are substantially identical to each other. As such,
the first gusset bracket will be described in detail with the
understanding that the second gusset bracket is substantially
equivalent thereto (and their coupling will be described below,
thereafter). First gusset bracket 50 comprises a base web 51, a
wall coupling portion 52 and an arm coupling portion 53. The base
web 51 forms the body of the structure, and in the configuration
shown, comprises a generally planar right triangle having two legs
that are associated with each other at right angles. The wall
coupling 52 comprises a flange, that, in the configuration shown,
extends from one of the legs generally perpendicular to the base
web. In the configuration shown, the wall coupling extends
generally along the entire length of the leg and is likewise
substantially planar. A plurality of openings are defined in the
wall coupling, and wall fasteners, such as wall fasteners 57 are
extendable therethrough.
[0046] The arm coupling portion 53 further comprises first wall 54
and second wall 55. The first wall 54 of the arm coupling portion
53 extends generally perpendicular to the base wall and on the same
side thereof as the wall coupling 52. The second wall extends from
the end of the first wall 54, opposite the base web 51, and extends
in a direction away from the base web. In the configuration shown,
the first wall and the second wall are substantially perpendicular,
such that the second wall is parallel to the base web 51. In other
words, the first wall 54 is separated from the base web by a
distance substantially equal to the width of the second wall 55 and
is perpendicular thereto.
[0047] As set forth above, the first gusset bracket 50 and second
gusset bracket 60 are substantially identical to one another. As
such, the second gusset bracket 60 comprises a base web 61, a wall
coupling portion 62 and an arm coupling portion 63. The base web 61
forms the body of the structure, and in the configuration shown,
comprises a generally planar right triangle having two legs that
are associated with each other at right angles. The wall coupling
62 comprises a flange, that, in the configuration shown, extends
from one of the legs generally perpendicular to the base web. In
the configuration shown, the wall coupling extends generally along
the entire length of the leg and is likewise substantially planar.
A plurality of openings is defined in the wall coupling, and wall
fasteners, such as wall fasteners 57 are extendable
therethrough.
[0048] The arm coupling portion 63 further comprises first wall 64
and second wall 65. The first wall 64 of the arm coupling portion
63 extends generally perpendicular to the base wall and on the same
side thereof as the wall coupling 62. The second wall extends from
the end of the first wall 64, opposite the base web 61, and extends
in a direction away from the base web. In the configuration shown,
the first wall and the second wall are substantially perpendicular,
such that the second wall is parallel to the base web 61. In other
words, the first wall 64 is separated from the base web by a
distance substantially equal to the width of the second wall 65 and
is perpendicular thereto.
[0049] To couple the structures together, the first gusset bracket
50 is, relative to the second gusset bracket 60, rotated 180
degrees about an axis that is centrally located relative to the
first and second walls of the arm couplings and substantially
parallel thereto. When relatively rotated and positioned together,
the arm coupling portions 53, and 63 of the first and second gusset
brackets 50, 60 form a pocket, or arm slot 67 (also in FIG. 5)
which has a cross-section substantially corresponding to the arm
member 20 proximate the proximal end, such that, and as will be
explained below, the arm member can be slidably inserted into the
arm slot.
[0050] The wall coupling member 22 further includes wall fasteners
57 and arm fasteners 59. Wall fasteners 57 are tapered and aligned
planer to the first wall coupling portion 52 and second wall
coupling portion 62. A plurality of wall fasteners 57 are used for
both the first gusset bracket 50 and second gusset bracket 60 in
such a number than the wall coupling member 22 is substantially
mated to the external surface. Wall fasteners 57 are vertically
aligned substantially in relation to one another between the first
gusset bracket 50 and second gusset bracket 60 of the wall coupling
member 22, in the configuration shown. The number of wall fasteners
57 are contemplated in different numbers per configurations of the
wall coupling member 22, first gusset bracket 50, and second gusset
bracket 60 sizes.
[0051] Arm fasteners 59 are axially aligned through the second wall
55 and second wall 65 of the first gusset bracket 50 and second
gusset bracket 60 of wall coupling member 22, respectively. Arm
fasteners run through both the first gusset bracket 50 and second
gusset bracket to secure and mate the arm member 20 (through
appropriate openings therein which are not shown) to the arm slot
67 created by the conjoined gusset members. Once secure, the first
side 32 of the arm member 20 will be mated and coupled to the
interior of first wall 64 of second gusset bracket 60 through the
axial alignment of the arm fasteners 59. Further, the second side
33 of the arm member 20 will be mated to the interior of the first
wall 54 of the first gusset bracket 50 through the axial alignment
of the arm fasteners 59. As contemplated in alternate
configurations, the fasteners may be of different sizes, lengths,
and possess alternate securing mechanisms including, but not
limited to, tapered screws, nails, or bolting systems. The base web
51 of the wall coupling member 22 for both gusset brackets is the
primary load member of the design. Additional fasteners may be
configured to extend through the first walls 54, 64 of the gusset
brackets as well, and, correspondingly through corresponding
openings of the arm member.
[0052] As is shown in FIGS. 2 and 3, the bar locking fastener 24 is
a securing device positioned within the locking opening 36 of the
arm member 20. The bar locking fastener comprises a flange nut 70
and bolt 80. The flange nut 70 has an upper portion 71 and lower
flange 73. It is to be understood the upper portion 71 is hexagonal
in shape and has size substantially corresponding to the locking
opening 37 such that when inserted thereinto, the flange not is
precluded from a complete rotation due to the correspondence of
shape (i.e., it is, at least to some extent, keyed). The upper
portion 71 and locking opening 37 may have alternative shapes in
contemplative configurations, as is discussed above, with the
understanding that relative rotation is limited.
[0053] Further, the lower flange 72 is of radially size
substantially larger than the locking opening 37, in such a way
that movement through the locking opening 37 for the lower portion
72 is not feasible when the upper portion is extended into an
operable position. The combination of features involving the flange
nut 70 results in a structure that can be axially slid into the
locking opening 37 from the inside (i.e., by being inserted into
the transverse opening prior to slidable insertion of the bar
member), without being able to slide through due to the lower
flange being larger than the locking opening. Further, due to the
hexagonal configuration about the upper portion 71 of the flange
nut 70, rotation of the flange nut 70 while in an operable position
within the locking opening is restricted due to the mated sides of
the hexagonal surface and the general corresponding structures.
[0054] The bolt 80 of bar locking fastener 24, as shown in FIG. 3,
comprises a head 81 and shaft 82, which further includes lower end
surface 83. The head 81 of the bolt 80 is mated to the shaft 82
which terminates at lower end surface 83. Shaft 82 is threaded and
matingly engages the threads of the flange nut 70. The length of
shaft 82 is dependent upon a the configuration of a number of
different structures, including but not limited to, the length of
flange nut 70, the size of the transverse opening, the
configuration of the bar member, and/or the thickness of the arm
member and is contemplated to be of varying lengths depending upon
use, material, and configuration of the pull up system 10.
[0055] To assemble the bar locking fastener 24 into an operable
configuration, first the flange nut 70 is inserted through the
locking opening 37. Placement is done from the interior of arm
member 20, such as, for example, through the transverse opening.
The upper portion 71 of the flange nut fits into the locking
opening 37 until the lower flange 73 is mated to the interior of
the top surface 34 of bar member 20. Following this, the shaft 82
of bolt 80 is placed axially in alignment with the interior of the
flange nut 70 and the two are threaded together It is desirable
that the head of the bolt is larger than the opening so that,
absent a bar member, the bolt does not fall through the locking
opening. Additionally, if the locking opening and the flange nut
are such that an interference fit can be created therebetween when
the flange nut is inserted into the locking opening.
[0056] Advantageously, with the present configuration, the assembly
of the subsystems to the pull up system 10 does not require welding
or other mating, and, instead the pull system 10 are assembled
using prefabricated fasteners of contemplated sizes and
lengths.
[0057] To assemble the pull up system of the present disclosure,
the user is first provided with the various components. For
example, in the configuration shown, the pull-up system 10 includes
one bar member 12, two arm members 20, and four gusset brackets.
The quantity of bar locking fasteners 24, wall fasteners 57, and
arm fasteners 59 are dependent upon a number of different factors.
It will be understood that while the system is shown with only two
arm members, it is contemplated that the system my include more
than two arm members and that the bar member may be of sufficient
length to require multiple arm members. Alternatively, multiple arm
members may be utilized with a separate bar member being positioned
therebetween, such that arm members between the end arm members
have a separate bar member extending from either side thereof.
[0058] The mounting of the pull up system will be described with
the mounting thereof onto a substantially vertical and planar
surface. Of course, the structure, a identified above, can be
mounted to any number of different outside devices. Mounting of the
pull up system 10 is initiated by the formation of the support
assembly. Specifically, the first gusset bracket 50 and the second
gusset bracket 60 are assembled by putting the second gusset
bracket is positioned in a manner opposite in relation to the first
gusset bracket 50. That is, the second gusset bracket 60 is rotated
180 degrees in relation to the first gusset bracket 50.
[0059] The positioning of the two forms the arm slot 67. And, the
arm member 20 is inserted into the arm slot 67 by insertion via
proximal end 30 thereinto. The arm slot, as discussed above is
substantially equal in height and width to the height and width of
the arm member 20 to allow insertion, while maintaining a,
preferably snug fit. In some configurations, the arm member may
form the body with the arm coupling portion being positionally
defined thereby. The arm member 20 is placed with proximal end 30
within the cavity until such point arm fasteners 59 are aligned
along the first wall 54, arm member 20, and first wall 64. The arm
fasteners 59 are secured through tapered insertion, using an
external tool to supply necessary force to thread the axially
aligned arm fasteners 59 through the first wall 54, first wall 64
and arm member 20.
[0060] The first of the support assemblies are now formed. As the
configuration shown has a pair of substantially identical support
assemblies, a second support assembly is formed by again coupling
an arm member with a wall coupling member having a first and second
gusset bracket.
[0061] In some configurations, the two support assemblies are
coupled to the vertical surface in a spaced apart orientation, and
in an orientation wherein the two arm members are mounted so as
correspond, and so that the transverse openings thereof align with
each other. In other configurations, the bar member is first
assembled, and then the entire structure may be mounted to an
outside structure. In either manner, it becomes necessary to mount
the support assembly to the vertical surface. In either instance,
the wall fasteners 57 are directed into the vertical surface. In
some configurations, the vertical surface may comprise studs or
wood/metal based structures wherein appropriate fasteners may
comprise lag bolts or the like. In other instances bolts may be
utilized, wherein the surface comprises a rack or other framework.
In still other configurations, masonry screws may be utilized. It
will be understood that the particular fasteners that are utilized
are not to be deemed limiting, and these are to be considered
exemplary.
[0062] To secure the bar member 12 to the arm member 20, with
reference to FIGS. 2 and 3, the bar locking fastener is first
coupled to the respective arm member. In particular, bar locking
member 24 is prepared by placing flange nut 70 within the locking
opening 37 in such a way that the upper portion 71 of the flange
nut is sufficiently mated to the locking opening while the lower
flange 73 of the flange nut 70 remains within the interior of the
arm member 20. Generally, the fit between the opening and the upper
portion of the flange nut comprises an interference fit. Typically,
although not required, the lower flange is mated to the interior of
the top surface 34 of the bar member. It will be understood that
the flange nut is directed between the top surface and the
transverse opening so as to allow passage of the arm member through
the transverse opening. The bolt is placed with lower end surface
83 of shaft 82 facing towards the bottom surface 35 of arm member
20 and threaded onto the nut to a desired depth (typically, this
would be such that the two do not separate, but that the bolt does
not obstruct the passage of the arm member therethrough). In the
configuration shown, each of the arm members have two transverse
openings, and, as such, a total of four bar locking fasteners may
be required for assembly.
[0063] Once the desired bar locking fasteners are formed, the bar
member 12 of the pull up system 10 is directed through a transverse
opening 36 of each one of the arm members 20 to which it is to be
coupled (which is two in the present configuration). As set forth
above, when assembled and coupled to a wall (or set up for
attachment of the bar member), the transverse opening 36 of the
first arm member 20 and the transverse opening 36 of the second arm
member 20 of the support assembly 14 are placed in substantial
alignment. It will be understood that the separate support
assemblies are positioned at a desired distance apart from each
other with the understanding that the bar member is of sufficient
length to span therebetween (and typically to have a portion extend
beyond each of the support assemblies). In many instances, the bar
member is sized appropriately for systems that will be mounted at
some multiple of 16'' on center, for example, as this will
correspond to the gap between studs or vertical supports in typical
construction in North America.
[0064] Upon placement of the bar member 12 into and through the
desired transverse openings, bolt 80 of the bar locking fastener 24
is tightened. Continued tightening will result in the lower end
surface 83 of the bolt 80 resting on the outer surface 19 of the
bar member 12 in such a way that it supplies a downward force that
forces a coupling between the bar member and arm member 20 through
the transverse opening, essentially sandwiching the bar member
between the bolt and the transverse opening perimeter. Because the
locking opening 37 which holds the bar locking faster 24 is of
substantially equal shape as the flange nut 70 upper portion 71,
the flange nut will not rotate any appreciable amount (i.e., an
amount that destroys the functionality of the combination) while
the bolt 80 is being placed and the flange precludes the passage of
the nut entirely through the locking opening.
[0065] Further bar members or arms can be provided and coupled as
desired to the appropriate transverse opening. From time to time,
it may be desirable to remove the bar member, or to move the bar
member to be between other transverse openings. In such an
instance, the user can loosen the appropriate bolts of the desired
bar locking fasteners to release the clamping hold on the
respective bar member. Once each of the bolts that retain the
particular bar member are loosened, the user can slidably remove
the bar member from interaction with the respective transverse
openings, and remove the bar member.
[0066] It is contemplated that while the particular support
assembly is shown, the bar locking fastener can be utilized with
other systems and with other types of pull up systems that include
different manners of coupling to outside structures. For example,
the particular type of fastener can be utilized, without
limitation, in the pull up support assemblies that are of the type
that are sold under the trade names P-3 Pull-Up System, P-4 Pull-Up
System, P-6V Garage Pull-Up System, P-5V Garage Pull-Up System
and/or the Infinity Flying Pull-Up Bar, each of which are available
from Rogue Fitness of Columbus, Ohio. In such systems, the support
assembly includes a wall coupling members and arm members that are
welded or otherwise joined together (with support members
buttressing the coupling in some configurations), Some of such
systems can be mounted from walls, ceilings or other structures
that may be neither substantially vertical, substantially
horizontal but substantially oblique to both the vertical and the
horizontal.
[0067] The foregoing description merely explains and illustrates
the disclosure and the disclosure is not limited thereto except
insofar as the appended claims are so limited, as those skilled in
the art who have the disclosure before them will be able to make
modifications without departing from the scope of the
disclosure.
