Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a Divisional of U.S. patent application
Ser. No. 13/676,802, filed Nov. 14, 2012, the disclosure of which
is incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] An embodiment of the present invention relates generally to
an adjustable rod assembly, and more particularly, to an adjustable
tension-mounted dual rod assembly.
[0003] Adjustable length tension-mounted rods for use as curtain or
shower curtain rods are generally known. These tension-mounted rods
typically include a single straight rod having a first straight
shaft that telescopingly receives a second straight shaft, wherein
the first and second shafts house a long threaded stud. Dual rod
assemblies, such as those having a curved shower curtain rod,
however, typically require the use of screws, bolts, and the like
in order to permanently fix the curved rod to support surfaces
through. This results in dual rod assemblies being more complex to
install and the risk of permanently damaging the support surfaces
upon removal of the assembly.
[0004] It is therefore desirable to provide an adjustable dual rod
assembly that is mounted between opposing support surfaces by a
tension rod mechanism, thereby providing for simpler installation
of the assembly and reducing, if not eliminating, the risk of
damage to the support surfaces upon removal of the assembly.
BRIEF SUMMARY OF THE INVENTION
[0005] Briefly stated, one embodiment of the present invention is
directed to an adjustable rod assembly comprising a first rod
assembly having a first tube of a generally straight configuration,
a second tube of a generally straight configuration, and a third
tube of a generally straight configuration. A first end of the
first tube is telescopingly received within the second tube and a
first end of the second tube is telescopingly received within the
third tube. The second tube is rotatable relative to the first tube
and the third tube. The adjustable rod assembly further comprises a
second rod assembly having a first tube and a second tube. A first
end of the first tube is telescopingly received within the second
tube. The adjustable rod assembly further comprises a first end
support, a second end support, and a tension rod mechanism fixedly
secured within the second tube of the first rod assembly for
rotational movement therewith. The third tube of the first rod
assembly and the second tube of the second rod assembly are secured
to the first end support. The respective first tubes of the first
and second rod assemblies are secured to the second end support.
The tension rod mechanism has a threaded portion configured to
extend into an interior of the first tube of the first rod
assembly.
[0006] Another embodiment of the present invention is directed to a
method of installing an adjustable rod assembly. The method
comprises: (a) providing an adjustable rod assembly including a
first straight rod assembly having a first straight tube and a
second straight tube, a second curved rod assembly having a first
arcuate tube and a second arcuate tube, and first and second end
supports, wherein each of the first and second straight tubes and
each of the first and second arcuate tubes has opposing first and
second ends; (b) assembling the adjustable rod assembly by: (i)
telescopingly positioning the first end of the first straight tube
in the second end of the second straight tube and telescopingly
positioning the first end of the first arcuate tube in the second
end of the second arcuate tube, (ii) pivotably securing the second
end of the first straight tube and the second end of the first
arcuate tube to the second end support, (iii) pivotably securing
the first end of the second arcuate tube to the first end support,
and (iv) rotatably securing the first end of the second straight
tube to the first end support; c) positioning the assembled
adjustable rod assembly between opposing support surfaces; d)
adjusting a length of the assembled adjustable rod assembly such
that a respective rear surface of each of the first and second end
supports is proximate a respective one of the opposing support
surfaces; and e) rotating the second straight tube about a
longitudinal axis thereof until the respective rear surface of each
of the first and second end supports directly contacts a respective
one of the opposing support surfaces and the assembled adjustable
rod assembly applies a compressive force against the opposing
support surfaces.
[0007] In another embodiment, the present invention is directed to
an adjustable tension rod assembly comprising a first straight rod
assembly and a second curved rod assembly. The first straight rod
assembly includes a first straight tube having a first end and a
second end, a second straight tube having a first end and a second
end, and a third straight tube having a first end and a second end.
The second end of the first straight tube is telescopingly received
within the second end of the second straight tube and the second
straight tube is rotatable relative to the first straight tube. The
first end of the second straight tube is rotatably and
telescopingly received within the second end of the third straight
tube. The second curved rod assembly includes a first arcuate tube
having a first end and a second end and a second arcuate tube
having a first end and a second end. The first end of the first
arcuate tube is telescopingly received within the second end of the
second arcuate tube. The adjustable tension rod assembly further
comprises a first end support, a second end support, and a tension
mechanism including a rod with a connector and a threaded portion.
The first end of the third straight tube and the first end of the
second arcuate tube are pivotably secured to the first end support
at spaced apart positions. The second end of the first straight
tube and the second end of the first arcuate tube are pivotably
secured to the second end support at spaced apart positions. The
connector of the tension mechanism is fixedly secured within the
first end of the second straight tube and rotatably secured within
the third straight tube. The threaded portion of the tension
mechanism is rotatably secured within the first straight tube by a
threaded bushing. Rotation of the second straight tube in a first
direction about a longitudinal axis of the second straight tube
causes the first and third straight tubes to move away from each
other and causes the first and second arcuate tubes to move away
from each other. Rotation of the second straight tube in a second
opposite direction about the longitudinal axis of the second
straight tube causes the first and third straight tubes to move
toward each other and causes the first and second arcuate tubes to
move toward each other.

those skilled in the art that the adjustable rod assembly 10 may
comprise only one straight or curved rod assembly 12, 100, two
generally straight rod assemblies 12, or two generally curved rod
assemblies 100.
[0021] The curved rod assembly 100 comprises a first, inner tube
112 having an arcuate portion and a second, outer tube 114 having
an arcuate portion. The first, inner arcuate tube 112 has a first
end 112a and a second end 112b. The second, outer arcuate tube 114
has a first end 114a and a second end 114b. The first end 114a of
the second arcuate tube 114 and the second end 112b of the first
arcuate tube 112 are each provided with a pair of diametrically
opposed apertures 116 (see FIG. 2). The first and second arcuate
tubes 112, 114 are preferably made from a metal, and more
preferably a non-corrosive metal, such as cold-rolled steel,
stainless steel, aluminum, chrome or nickel or alloys or
combinations thereof, but may also be constructed using wood,
plastic, acrylic, or a like strong, lightweight material or a
combination of materials. The first and second arcuate tubes 112,
114 may also be coated with any type of known coating for applying
a non-corrosive finish to the curved rod assembly 100.
[0022] The first and second arcuate tubes 112, 114 are both
preferably generally cylindrical in shape with a circular cross
section. However, it will be understood by those skilled in the art
that any other suitable cross-sectional shape may be used,
including oval, square, rectangular, hexagonal, octagonal, and the
like. Preferably, the outer diameter of the first arcuate tube 112
is at least slightly smaller than the inner diameter of the second
arcuate tube 114, such that first arcuate tube 112 is telescopingly
received within the second arcuate tube 114 in a reasonably tight
fit. More particularly, in an assembled position of the adjustable
rod assembly 10, the first end 112a of the first arcuate tube 112
is telescopingly positioned or received within the second end 114b
of the second arcuate tube 114. Accordingly, the first and second
arcuate tubes 112, 114 of the curved rod assembly 100 are
telescopingly configured.
[0023] The straight rod assembly 12 comprises a first, inner tube
14 of a generally straight configuration and a second, outer tube
16 of a generally straight configuration. The first, inner straight
tube 14 has a first end 14a and a second end 14b. The second, outer
straight tube 16 has a first end 16a and a second end 16b. The
second end 14b of the first straight tube 14 is provided with a
pair of diametrically opposed apertures 18. The first and second
straight tubes 14, 16 are preferably made from a metal, and more
preferably a non-corrosive metal, such as cold-rolled steel,
stainless steel, aluminum, chrome or nickel or alloys or
combinations thereof, but may also be constructed using wood,
plastic, acrylic, or a like strong, lightweight material or a
combination of materials. The first and second straight tubes 14,
16 may also be coated with any type of known coating for applying a
non-corrosive finish to the straight rod assembly 12.
[0024] The first and second straight tubes 14, 16 are both
preferably generally cylindrical in shape with a circular cross
section. However, it will be understood by those skilled in the art
that any other suitable cross-sectional shape may be used,
including oval, square, rectangular, hexagonal, octagonal, and the
like. Preferably, the outer diameter of the first straight tube 14
is at least slightly smaller than the inner diameter of the second
straight tube 16, such that first straight tube 14 is telescopingly
received within the second straight tube 16 in a reasonably tight
fit. More particularly, in an assembled position of the adjustable
rod assembly 10, the first end 14a of the first straight tube 14 is
telescopingly positioned or received within the second end 16b of
the second straight tube 16. Accordingly, the first and second
straight tubes 14, 16 of the straight rod assembly 12 are
telescopingly configured.
[0025] The second straight tube 16 of the straight rod assembly 12
is preferably a rotatable tube. More particularly, the second
straight tube 16 of the straight rod assembly 12 is preferably
rotatable about a longitudinal axis X1 thereof. Further, in the
assembled position of the adjustable rod assembly 10, the
longitudinal axis X1 of the second straight tube 16 of the straight
rod assembly 12 is preferably generally aligned with the
longitudinal axis X2 of the first straight tube 14 of the straight
rod assembly 12. As such, in the assembled position of the
adjustable rod assembly 10, the second straight tube 16 is
preferably freely rotatable relative to the first straight tube 14
positioned therein.
[0026] Preferably, the first and second straight tubes 14, 16 are
each at least partially hollow, such that a tension mechanism 20
can be fitted therein (see FIGS. 2A-2C). More specifically, the
tension mechanism 20 is fixedly secured within an interior of the
second straight tube 16, and more preferably within the first end
16a of the second straight tube 16, such that the tension mechanism
20 is configured to rotate with the second straight tube 16. U.S.
Pat. No. 5,330,061, which is assigned to Zenith Products Corp. and
is incorporated herein by reference, describes a preferred
embodiment of a tension mechanism of the type for use in the
adjustable rod assembly 10.
[0027] Specifically, referring to FIG. 2C, the tension mechanism 20
of the straight rod assembly 12 is preferably a tension rod
mechanism 20 comprising a rod 22 having a first end 22a, a second
end 22b, a first stop piece 24 and a second stop piece 26. The
first stop piece 24 is provided at the first end 22a of the rod 22,
while the second stop piece 26 is positioned in between the first
and second ends 22a, 22b. The first and second stop pieces 24, 26
may be shaped differently, as shown in FIG. 2C, or alternatively
may have substantially identical structures. As will be discussed
more fully herein, the first and second stop pieces 24, 26 define
the limits to which the overall length of the adjustable rod
assembly 10 can be adjusted.
[0028] The rod 22 comprises a threaded portion 28, an unthreaded
portion 30 and a connector portion 32. The threaded portion 28 of
the rod 22 is defined by the portion of the rod 22 having an
external thread pattern. Preferably, at least one part of the
threaded portion 28 of the rod 22 is flexible. More preferably, the
entirety of the threaded portion 28 of the rod 22 is flexible.
However, it will be understood by those skilled in the art that a
portion or the entirety of the threaded portion 28 of the rod 22
may alternatively be generally rigid. In one embodiment, as shown
in FIG. 2C, the threaded portion 28 of the rod 22 extends from the
second end 22b of the rod 22 and the first stop piece 24 to the
second stop piece 26.
[0029] The connector portion 32 of the rod 22 preferably comprises
a connector 34 which defines the first end 22a of the rod 22. At a
distal tip of the connector 34, a locking pin 36 is integrally
formed with the connector 34. However, it will be understood that
the locking pin 36 may be formed as a separate component which is
secured to the connector 34 by any conventional means. The locking
pin 36 protrudes outwardly from a surface of the connector 34 and
also from the threaded and unthreaded portions 28, 30 of the rod
22.
[0030] The unthreaded portion 30 of the rod 22 extends from the
second stop piece 26 to the connector 34 at the first end 22a of
the rod 22. Preferably, at least one part of the unthreaded portion
30 of the rod 22 is flexible. More preferably, the entirety of the
unthreaded portion 30 of the rod 22 is flexible. However, it will
be understood by those skilled in the art that a portion or the
entirety of the unthreaded portion 30 of the rod 22 may
alternatively be generally rigid.
[0031] In the assembled position of the adjustable rod assembly 10,
the first end 14a of the first straight tube 14 is telescopingly
positioned within the interior of the second straight tube 16, and
the first end 112a of the first arcuate tube 112 is telescopingly
positioned within the interior of the second arcuate tube 114.
Further, the connector portion 32 of the tension mechanism 20 is
fixedly secured within the first end 16a of the second straight
tube 16 and at least a portion of the threaded portion 28 of the
rod 22 extends into and is rotatably secured within the first
straight tube 14. More preferably, the connector 34 of the rod 22
is fixedly secured within the first end 16a of the second straight
tube 16, the unthreaded portion 30 of the rod 22 is positioned
within an interior of the second straight tube 16, and at least a
portion of the threaded portion 28 of the rod 22 extends into an
interior of the first end 14a of the first straight tube 14.
Accordingly, rotation of the second straight tube 16 about the
longitudinal axis X1 thereof, relative to the first straight tube
14, also causes rotation of the rod 22 of the tension mechanism 20
relative to the first straight tube 14.
[0032] In one embodiment, at least a portion of an interior surface
of the first end 14a of the first straight tube 14 preferably
includes a threaded portion which is configured to threadingly
engage the threaded portion 28 of the rod 22 to rotatably secure
the rod 22 within the first straight tube 14. In another
embodiment, the interior of the first end 14a of the first straight
tube 14 preferably includes a threaded bushing or nut 38 configured
to threadingly engage the threaded portion 28 of the rod 22 to
rotatably secure the rod 22 therein. The threaded bushing 38 is
preferably fixedly secured within the first end 14a of the first
straight tube 14. More preferably, the threaded bushing 38 is
positioned at substantially a distal-most tip of the first end 14a
of the first straight tube 14. However, it will be understood by
those skilled in the art that the threaded bushing 38 may be
positioned at some other location within the first straight tube
14, as long as the location allows extension and collapse of the
adjustable rod assembly 10 to the desired length.
[0033] The threaded bushing 38 is preferably made from a metal,
such as cold-rolled steel, stainless steel, aluminum, chrome or
nickel or alloys or combinations thereof, but may also be
constructed using wood, plastic, acrylic, or a like strong,
lightweight material or a combination of materials. The threaded
bushing 38 may be secured within the first straight tube 14 by any
conventional means, such as a flange connection, a dimple
connection, adhesives, welds and the like. Preferably, the threaded
bushing 38 is secured within the first end 14a of the first
straight tube 14 by a flange 40 which extends circumferentially
from the threaded bushing 38 around at least a portion of the
distal-most tip of the first end 14a of the first straight tube
14.
[0034] Preferably, an exterior surface of the threaded bushing 38
is in direct contact with an interior surface of the first straight
tube 14. An interior surface of the threaded bushing 38 is
preferably defined by a centrally located and threaded through-hole
42. The thread pattern of the through-hole 42 corresponds to or
complements that of the threaded portion 28 of the rod 22. The
centrally located through-hole 42 of the threaded bushing 38 also
includes an inner diameter that is substantially equal to the outer
diameter of the threaded portion 28 of the rod 22. Accordingly, in
the assembled position of the adjustable rod assembly 10, and more
particularly in the assembled position of the straight rod assembly
12, the threaded portion 28 of the rod 22 is positioned within the
centrally located through-hole 42 of the threaded bushing 38, such
that the threaded portion 28 of the rod 22 rotates within the
threaded bushing 38.
[0035] Preferably, rotation of the second straight tube 16 causes
the first straight tube 14 and the second straight tube 16 to move
axially relative to each other. More particularly, rotation of the
second straight tube 16 in a first direction about the longitudinal
axis X1 thereof preferably causes the first straight tube 14 and
the second straight tube 16 move away from each other, thereby
extending a length L1 of the straight rod assembly 12. Rotation of
the second straight tube 16 in the first direction, and more
particularly movement of the threaded portion 28 within the
threaded bushing 38 as the second straight tube 16 is rotated in
the first direction, is preferably limited by the second stop piece
26.
[0036] Rotation of the second straight tube 16 in a second
direction, opposite the first direction, about the longitudinal
axis X1 thereof preferably causes the first straight tube 14 and
the second straight tube 16 to move axially toward each other,
thereby reducing the length L1 of the straight rod assembly 12.
Rotation of the second straight tube 16 in the second direction,
and more particularly movement of the threaded portion 28 within
the threaded bushing 38 as the second straight tube 16 is rotated
in the second direction, is preferably limited by the first stop
piece 24.
[0037] Referring to FIGS. 3A-3C, the straight rod assembly 12
further comprises a third tube 44 which is preferably generally
cylindrical in shape with a circular cross section and which
preferably has a generally straight configuration. The third tube
44 is preferably a generally cylindrical coupler 44. The coupler 44
has a first end 44a and a second end 44b. Referring to FIG. 4, in
one embodiment, the coupler 44 preferably includes at least one
generally closed interior and intermediate wall 46 (see FIG. 4) at
a position between the opposing first and second ends 44a, 44b.
Preferably, the interior and intermediate wall 46 includes an
aperture or groove 46a formed therein. More preferably, the
interior and intermediate wall 46 includes a centrally-located
aperture 46a formed therethrough. The first end 44a of the coupler
44 preferably includes a pair of diametrically opposed apertures
48.
[0038] The inner diameter of the coupler 44 is at least slightly
larger than the outer diameter of the second straight tube 16, such
that the second straight tube 16 can be positioned within an
interior of the coupler 44. More particularly, in the assembled
position of the adjustable rod assembly 10, the first end 16a of
the second straight tube 16 of the straight rod assembly 12 is
telescopingly positioned and received within the second end 44b of
the coupler 44. Preferably, the second straight tube 16 is
rotatably secured within the coupler 44, such that the second
straight tube 16 is freely rotatable relative to the coupler
44.
[0039] In one embodiment, the preferred structural configuration of
the second straight tube 16 and the coupler 44 is achieved by
rotational engagement of the locking pin 36 and the aperture or
groove 46a of the intermediate wall 46 of the coupler 44. More
particularly, in one embodiment, the first end 16a of the second
straight tube 16, in which the connector 34 of the tension
mechanism 20 is fixedly secured, is positioned within the second
end 44b of the coupler 44 until the locking pin 36 of the connector
34 passes through the aperture 46a of the intermediate wall 46.
Preferably, at least a portion of the locking pin 36 has a diameter
which is at least slightly larger than that of the aperture 46a,
such that once the locking pin 36 is positioned within the aperture
46a (e.g., by snapping the locking pin 36 into position), the
locking pin 36 is frictionally engaged by the aperture 46a and is
not easily detached or removed from the aperture 46a.
[0040] Such an engagement between the tension mechanism 20 and the
coupler 44 secures the tension mechanism 20 to the coupler 44 in a
stable manner, while simultaneously enabling both the second
straight tube 16 and the tension mechanism 20 to rotate relative to
the coupler 44 and the first straight tube 14, as necessary for
adjustment of the overall length of the adjustable rod assembly 10
and the generation of a tensile or compressive force which holds
the adjustable rod assembly 10 in place between opposing supporting
surfaces. More particularly, rotation of the second straight tube
16 in the first direction about the longitudinal axis X1 thereof
preferably causes the first straight tube 14 and the coupler 44 to
move away from each other, thereby extending the overall length of
the straight rod assembly 12, as well as that of the curved rod
assembly 100 and the adjustable rod assembly 10. Conversely,
rotation of the second straight tube 16 in the second, opposite
direction about the longitudinal axis X1 thereof preferably causes
the first straight tube 14 and the coupler 44 to move toward each
other, thereby reducing the length L1 of the straight rod assembly
12, as well as that of the curved rod assembly 100 and the
adjustable rod assembly 10.
[0041] The coupler 44 is preferably made from a metal, and more
preferably a non-corrosive metal, such as cold-rolled steel,
stainless steel, aluminum, chrome or nickel or alloys or
combinations thereof, but may also be constructed using wood,
plastic, acrylic, or a like strong, lightweight material or a
combination of materials. The coupler 44 may also be coated with
any type of known coating for applying a non-corrosive finish to
the coupler 44. More preferably, the coupler 44 is made from the
same material as the first and second tubes 14, 16.
[0042] The adjustable rod assembly 10 further comprises a first end
support 50 and a second end support 52. Each of the first and
second end supports 50, 52 is configured to be removably mounted to
a respective support surface (not shown) of the two opposing
support surfaces. The coupler 44 of the straight rod assembly 12
and the first end 114a of the second arcuate tube 114 are both
secured to the first end support 50. The second end 14b of the
first straight tube 14 and the second end 112b of the first arcuate
tube 112 are both secured to the second end support 52.
[0043] The first end and second end supports 50, 52 are preferably
made from a lightweight, high strength material, such as
cold-rolled steel, stainless steel, aluminum, chrome or nickel or
alloys or combinations thereof, but may also be constructed using
wood, plastic, acrylic, or a like strong, lightweight material or a
combination of materials, without departing from the spirit and
scope of the invention. Preferably, the first and second end
supports 50, 52 are made from the same material as the straight rod
assembly 12 and the curved rod assembly 100. One or both of the
first and second end supports 50, 52 may optionally be provided
with a decorative cover 54.
[0044] The first end support 50 is preferably a mirror image of the
second end support 52. For convenience in the description and
clarity in the drawings, only the first end support 50 is described
in detail and completely labeled in the drawings with the
understanding that the second end support 52 includes similar
features.
[0045] Referring to FIGS. 3A-3C, the first end support 50 includes
a base plate 56 having a first, rear face 56a and an opposing
second, front face 56b. Preferably, a resilient pad 58 is secured
to the rear surface 56a of the base plate 56 and is configured to
directly contact one of the opposing support surfaces to support
the adjustable rod assembly 10 above a ground surface when the
assembly is installed. The resilient pad 58 may be made of a rubber
(natural or synthetic), foam, an elastomeric plastic or any other
resilient material having a sufficiently high coefficient of
friction to ensure secure mounting of the adjustable rod assembly
10 between the two opposing support surfaces.
[0046] A first flange 60 and a second flange 62 extend generally
perpendicularly from the front face 56b of the base plate 56 of the
first end support 50. The first and second flanges 60, 62 are
spaced apart from each other so as to form a first support area 64
and a second support area 66 therebetween. Preferably, the first
support area 64 is spaced apart from the second support area 66. A
first aperture 60a and a second aperture 60b are formed in the
first flange 60. A first aperture 62a and a second aperture 62b are
formed in the second flange 62. Preferably, the respective first
apertures 60a, 62a of the first and second flanges 60, 62 are
generally aligned or in registry with each other and the first
support area 64 is formed therebetween. Preferably, the respective
second apertures 60b, 62b of the first and second flanges 60, 62
are generally aligned or in registry with each other and the second
support area 66 is formed therebetween.
[0047] In one embodiment, the straight rod assembly 12 is secured
between and to the first support areas 64 of the first and second
end supports 50, 52. Specifically, the first support area 64 of the
first end support 50 preferably receives the first end 44a of the
coupler 44 of the straight rod assembly 12 in a stable manner, and
the first support area 64 of the second end support 52 preferably
receives the second end 14b of the first straight tube 14 of the
straight rod assembly 12 in a similarly stable manner.
[0048] In one embodiment, a first fastener assembly comprising a
first fastening pin 68 and a first fastening pin end 70 is utilized
to secure the coupler 44 within the first support space 64 formed
between the first and second flanges 60, 62 of the first end
support 50. Specifically, in the assembled position of the
adjustable rod assembly 10, the first end 44a of the coupler 44 is
positioned within the first support space 64, such that the
apertures 48 of the first end 44a of the coupler 44 are generally
aligned or in registry with the respective first apertures 60a, 62a
of the first and second flanges 60, 62. The first fastening pin 68
and the first fastening pin end 70 are then inserted through the
respective first apertures 60a, 62a of the first end support 50 and
the apertures 48 of the coupler 44. The first fastening pin 68 may
be secured within the first fastening pin end 70 by any known
conventional mechanisms, such as corresponding thread patterns, an
adhesive, friction fit, an interference fit and the like. As such,
the coupler 44, and more particularly the first end 44a of the
coupler 44, is pivotably secured to the first end support 50.
However, it will be understood by those skilled in the art that the
coupler 44 may alternatively be fixedly secured to the first end
support 50.
[0049] Preferably, the second end 14b of the first straight tube 14
is pivotably secured to the first support area 64 of the second end
support 52 in a similar manner. Specifically, a second fastening
pin and a second fastening pin end of a second fastening assembly
(not shown) engage the respective first apertures 60a, 62a of the
first and second flanges 60, 62 of the second end support 52 and
the apertures 18 of the second end 14b of the first straight tube
14 to pivotably secure the first straight tube 14 to the second end
support 52. However, it will be understood by those skilled in the
art that the second end 14b of the first straight tube 14 may
alternatively be fixedly secured to the second end support 52.
[0050] In one embodiment, the curved rod assembly 100 is secured
between and to the second support areas 66 of the first and second
end supports 50, 52. Specifically, the second support area 66 of
the first end support 50 preferably receives the first end 114a of
the second arcuate tube 114 in a stable manner, and the second
support area 66 of the second end support 52 preferably receives
the second end 112b of the first arcuate tube 112 in a stable
manner.
[0051] In one embodiment, a third fastener assembly comprising a
third fastening pin 72 and a third fastening pin end 74 is
preferably utilized to secure the first end 114a of the second
arcuate tube 114 within the second support space 66 formed between
the first and second flanges 60, 62 of the first end support 50.
Specifically, in the assembled position of the adjustable rod
assembly 10, the first end 114a of the second arcuate tube 114 is
positioned within the second support area 66, such that the
apertures 116 of the first end 114a of the second arcuate tube 114
are generally aligned or in registry with the respective second
apertures 60b, 62b of the first and second flanges 60, 62. The
third fastening pin 72 and the third fastening pin end 74 are then
inserted through the respective second apertures 60b, 62b of the
first end support 50 and the apertures 116 of the first end 114a of
the second arcuate tube 114. The third fastening pin 72 may be
secured within the third fastening pin end 74 by any known
conventional mechanisms, such as corresponding thread patterns, an
adhesive, friction fit, an interference fit and the like. As such,
the second arcuate tube 114, and more particularly the first end
114a of the second arcuate tube 114, is pivotably secured to the
first end support 50.
[0052] Preferably, the second end 112b of the first arcuate tube
112 is pivotably secured to the second support area 66 of the
second end support 52 in a similar manner. Specifically, a fourth
fastening pin and a fourth fastening pin end of a fourth fastening
assembly (not shown) engage the respective second apertures 60b,
62b of the first and second flanges 60, 62 of the second end
support 52 and the apertures 116 of the second end 112b of the
first arcuate tube 112 to pivotably secure the first arcuate tube
112 to the second end support 52. As such, pivotal movement of the
curved rod assembly 100 is enabled.
[0053] In use, to obtain an assembled adjustable rod assembly 10,
both the straight rod assembly 12 and the curved rod assembly 100
must be placed in assembled positions. To place the curved rod
assembly 100 in the assembled position, the first end 112a of the
first arcuate tube 112 is positioned within the second end 114b of
the second arcuate tube 114, such that the first and second tubes
112, 114 are telescopingly configured. Also, the first end 114a of
the second arcuate tube 114 is pivotably secured to the second
support area 66 of the first end support 50, and the second end
112b of the first arcuate tube 112 is pivotably secured to the
second support area 66 of the second end support 52.
[0054] To place the straight rod assembly 12 in the assembled
position: the first end 14a of the first straight tube 14 is
positioned within the second end 16b of the second straight tube
16, such that the first and second tubes 14, 16 are telescopingly
configured and the second straight tube 16 is freely rotatable
relative to the first straight tube 14; the connector portion 32 of
the rod 22 of the tension mechanism 20 is fixedly secured within
the first end 16a of the second straight tube 16 and at least a
portion of the threaded portion 28 of the rod 22 extends from the
second straight tube 16 into the first straight tube 14 where it is
rotatably secured therein by the threaded bushing 38; the first end
16a of the second straight tube 16 is rotatably secured within the
second end 44b of the coupler 44 such that the locking pin 36 of
the connector 34 is positioned within the aperture 46a of the
intermediate wall 46 of the coupler 44; the first end 44a of the
coupler 44 is pivotably secured to the first end support 50; and
the second end 16b of the second straight tube 16 is pivotably
secured to the second end support 52.
[0055] Accordingly, in the assembled adjustable rod assembly 10,
both ends of the curved rod assembly 100 (i.e., first end 114a of
the second arcuate tube 114 and the second end 112b of the first
arcuate tube 112) are pivotably secured to the first and second end
supports 50, 52. Also, in the assembled adjustable rod assembly 10,
one end of the straight rod assembly 12 (i.e., the second end 14b
of the first straight tube 14) is pivotably secured to the second
end support 52, while the other end of the straight rod assembly 12
is rotatably secured to the first end support 50. More
particularly, while the coupler 44 is pivotably secured to the
first end support 50, the second straight tube 16 remains rotatable
relative to the first end support 50. Thus, the second straight
tube 16 is rotatably secured to the first end support 50, such that
rotational movement of the second straight tube 16 is enabled in
the assembled position of the adjustable rod assembly 10.
[0056] Since both rod assemblies 12, 100 are secured to the first
and second end supports 50, 52, any adjustment of the length L1 of
the straight rod assembly 12 results in a similar adjustment of the
overall length L2 of the curved rod assembly 100, and accordingly
of the overall length of the entire adjustable rod assembly 10.
Specifically, as the second straight tube 16 is rotated in either
the first or second direction, causing movement of the first and
second straight tubes 14, 16 either away from or toward each other,
the first and second arcuate tubes 112, 114 will similarly move
either away from or toward each other.
[0057] To install the assembled adjustable rod assembly 10 in a
bathtub or shower stall (not shown), the assembly 10, with the
straight rod assembly 12 and the curved rod assembly 100 both in
their respective assembled positions, is positioned between the
opposing support surfaces of the stall and the lengths L1, L2 of
both rod assemblies 12, 100 are adjusted until the desired overall
length of the adjustable rod assembly 10 is achieved. As described
above, the length L2 of the curved rod assembly 100 is adjusted by
sliding the first and second tubes 112, 114 either toward or away
from each other until the initial desired length is achieved.
Similarly, the length L1 of the straight rod assembly 12 is
similarly adjusted by sliding the first and second straight tubes
14, 16 either toward or away from each other until the initial
desired length is achieved.
[0058] The desired overall length of the adjustable rod assembly 10
is dependent upon the distance between the opposing support
surfaces and is achieved when the rear face 56a of the base plate
56 (or the resilient pad 58 attached thereto) of each end support
50, 52 is proximate a respective opposing support surface. More
preferably, the desired overall length of the adjustable rod
assembly 10 is achieved when the rear face 56a of the base plate 56
or (the resilient pad 58 attached thereto) of each end support 50,
52 directly contacts or almost directly contacts a respective
opposing support surface at generally the same height, such that
the first and second straight tubes 14, 16 and the first and second
arcuate tubes 112, 114 are generally horizontal in the mounted
configuration.
[0059] Finally, once the assembled adjustable rod assembly 10 is
properly positioned between the two opposing support surfaces, the
second straight tube 16 can be manually rotated by a user to
generate a tension or compressive force to be exerted by the
adjustable rod assembly 10 upon the opposing support surfaces, such
that the assembly 10 is maintained between the two opposing
surfaces without the use of fasteners or adhesives. Specifically,
when the assembled adjustable rod assembly 10 is positioned between
the two opposing surfaces, the user manually rotates second
straight tube 16 about its longitudinal axis X1, thereby extending
the length L1 of the straight rod assembly 12. The length L2 of the
curved rod assembly 100 is similarly extended, since the
telescoping first and second arcuate tubes 112, 114 will naturally
move away from each other as the first and second straight tubes
14, 16 do so.
[0060] Rotation of the second straight tube 16 is performed until
the rear surface 56a of the base plate 56 or (the resilient pad 58
attached thereto) of each end support 50, 52 directly contacts a
respective opposing support surface and a compressive or tensile
force, generated by the tension mechanism 20, is applied or exerted
against the opposing support surfaces. In one embodiment, upon
rotation of the second straight tube 16, the threaded portion 28 of
the rod 22 becomes flexed within the interior of the first straight
tube 14, thereby causing the adjustable rod assembly 10 to exert a
force against the opposing support surfaces and providing
sufficient tension to maintain a secure fit between the surfaces.
Preferably, a compressive or tensile force is also generated and
exerted between the threads of bushing 38 and the threads of
threaded portion 28 to maintain the position of bushing 38 along
the threaded portion 28. As such, the adjustable rod assembly 10 is
maintained between the two opposing surfaces without the use of
fasteners or adhesives.
[0061] Those skilled in the art will appreciate that changes could
be made to the embodiments described above without departing from
the broad inventive concept thereof. It is understood, therefore,
that this invention is not limited to the particular embodiments
disclosed, but it is intended to cover modifications within the
spirit and scope of the present invention as defined by the
appended claims.
