[0001] Benefit is claimed from U.S. Patent Application No.
63/127,498, filed Dec. 18, 2020, U.S. Patent Application No.
63/127,509, filed Dec. 18, 2020 and U.S. Patent Application No.
63/127,525, filed Dec. 18, 2020, the entire contents and
disclosures of these applications are incorporated, in entirety,
herein by reference.
FIELD
[0002] The present disclosure is a patent application and relates
generally to provision of tension to a member, and associated
structures and methods, and within a specific example relates to
provision of tension to a member in a direction transverse to an
anchor point and which permits some articulation movement of the
member.
BACKGROUND
[0003] Within many situations it is desired to attach and tension a
member to an anchor point. Within an example, the tensioned member
is an elongated rod. Within an example, the elongated rod is
further attached to a cable made of metal of the like. Within an
example, the elongate rod is at least partially threaded and
extends through an aperture at the anchor point. Within an example,
a threaded nut is mated with the threaded portion on the elongated
rod. Turning of the nut relative to the elongated rod may cause the
elongated rod to be pulled in a direction through aperture at the
anchor point. Such pulling causes a tension force to be built-up
within the elongated rod.
[0004] For some example circumstances, it is desired that the
member (e.g., elongated rod) have a major extent (e.g., the
elongation of the elongated rod) that is transverse, generally
perpendicular, to the anchor point. As such, the tension force is
transverse, generally perpendicular, to the anchor point.
BRIEF SUMMARY
[0005] The following presents a simplified example summary in order
to provide a basic understanding of some aspects of the present
disclosure. This summary is not an extensive overview of the
present disclosure. It is intended to neither identify key or
critical elements nor delineate the scope of the present
disclosure. Its sole purpose is to present some concepts of the
present disclosure in a simplified form as a prelude to the more
detailed description that is presented later.
[0006] For some example circumstances of attaching and tensioning a
member to an anchor point, some articulation movement of the member
(e.g., elongated rod) is permitted and/or simply occurs. For some
example circumstances, the articulation movement may occur
repeatedly over time. Such, repeated articulation movement may be
associated with changes in a load force that may also be present
within the member. Such, changing load force may be cyclic. It is
possible that changes in a load force may increase a possibility of
a reduction of the tension force (e.g., an increased possibility
for the nut to loosen).
[0007] As part(s) of an arrangement that includes the member (e.g.,
elongated rod) and the nut, one or more washers may also be
provided. For some example circumstances, it is desirable to avoid
binding of the one or more washers that may occur during
articulation movement of the member that may occur and/or changes
in the load force that may present within the member. For some
specific example circumstances, it is desirable to avoid binding of
the one or more washers that may occur during articulation movement
of the member that may occur and/or changes in the load force that
may present within the member with the major extent (e.g., the
elongation of the elongated rod) being transverse, generally
perpendicular, to the anchor point and the tension force being
transverse, generally perpendicular, to the anchor point.
[0008] For some example circumstances, it is desirable to avoid
wear and/or fatigue that may occur within an arrangement during
articulation movement of the member that may occur and/or changes
in the load force that may present within the member. For some
specific example circumstances, it is desirable to avoid wear
and/or fatigue that may occur within the arrangement during
articulation movement of the member that may occur and/or changes
in the load force that may present within the member with the major
extent (e.g., the elongation of the elongated rod) being
transverse, generally perpendicular, to the anchor point and the
tension force being transverse, generally perpendicular, to the
anchor point.
[0009] In accordance with at least some aspects, the present
disclosure provides an articulating-tension arrangement for
tensioning against and articulation relative to an anchor point.
The arrangement includes an elongate member for extension through
an aperture at the anchor point and having an elongation extending
in a direction generally transverse to the anchor point. The
arrangement includes a tightening member operable for providing a
tension force toward the elongate member to pull the elongate
member through the aperture. The arrangement includes an
articulating-tension washer, to be retained at the aperture to
transmit force between the tightening member and the anchor point,
and includes an arcuate surface for location away from the
aperture, the arcuate surface extending in an arc symmetrically
across the direction of elongation of the elongate member.
[0010] In accordance with at least some aspects, the present
disclosure provides an articulating-tension arrangement for
tensioning against and articulation relative to an anchor point
having a bearing face extending is a plane and an aperture
therethrough. The arrangement includes an elongate member for
extension through the aperture. The elongate member has an
elongation extending in a direction generally transverse to the
plane. The arrangement includes a tightening member operable for
providing a tension force toward the elongate member to pull the
elongate member through the aperture. The arrangement includes an
articulating-tension washer, to be retained relative to the bearing
face to transmit force between the tightening member and the anchor
point, that includes an arcuate surface for location away from the
bearing face. The arcuate surface extends in an arc symmetrically
across the direction of elongation of the elongate member.
[0011] I In accordance with at least some aspects, the present
disclosure provides an articulating-tension washer for an
articulating-tension arrangement to be tensioned against and to
permit articulation relative to an anchor point having a bearing
face extending in a plane and an aperture therethrough, the
arrangement including an elongate member for extending through the
aperture, the elongate member having an elongation extending in a
direction generally transverse to the plane, and the arrangement
including a tightening member operable for providing a tension
force toward the elongate member to pull the elongate member
through the aperture, wherein the articulating-tension washer, to
be retained relative to the bearing face to transmit force between
the tightening member and the anchor point, and the

DETAILED DESCRIPTION
[0025] Subject matter will now be described more fully hereinafter
with reference to the accompanying drawings, which form a part
hereof, and which show, by way of illustration, specific example
embodiments. This description is not intended as an extensive or
detailed discussion of known concepts. Details that are known
generally to those of ordinary skill in the relevant art may have
been omitted, or may be handled in summary fashion.
[0026] Certain terminology is used herein for convenience only and
is not to be taken as a limitation on the disclosed subject matter.
Relative language used herein is best understood with reference to
the drawings, in which like numerals are used to identify like or
similar items. Further, in the drawings, certain features may be
shown in somewhat schematic form.
[0027] The following subject matter may be embodied in a variety of
different forms, such as methods, devices, components, and/or
systems. Accordingly, this subject matter is not intended to be
construed as limited to any illustrative embodiments set forth
herein as examples. Rather, the embodiments are provided herein
merely to be illustrative.
[0028] Provided herein are examples of an articulating-tension
washer, an articulating-tension arrangement that includes an
articulating-tension washer, and a system that includes an
articulating-tension arrangement with an articulating-tension
washer therein. Also provided herein are example methods of
providing and using such.
[0029] Within an example and in accordance with an aspect, the
present disclosure provides an articulating-tension arrangement for
tension against and articulation relative to an anchor point. The
arrangement includes an elongate member for extension through an
aperture at the anchor point and having an elongation extending in
a direction generally transverse to the anchor point. The
arrangement includes a tightening member operable for providing a
tension force toward the elongate member to pull the elongate
member through the aperture. The arrangement includes an
articulating-tension washer, to be retained at the aperture to
transmit force between the tightening member and the anchor point,
that includes an arcuate surface for location away from the
aperture, the arcuate surface extending in an arc symmetrically
across the direction of elongation of the elongate member.
[0030] Within an example and in accordance with an aspect, the
present disclosure provides an articulating-tension arrangement for
tension against and articulation relative to an anchor point having
a bearing face extending is a plane and an aperture therethrough.
The arrangement includes an elongate member for extension through
the aperture. The elongate member has an elongation extending in a
direction generally transverse to the plane. The arrangement
includes a tightening member operable for providing a tension force
toward the elongate member to pull the elongate member through the
aperture. The arrangement includes an articulating-tension washer,
to be retained relative to the bearing face to transmit force
between the tightening member and the anchor point, that includes
an arcuate surface for location away from the bearing face. The
arcuate surface extends in an arc symmetrically across the
direction of elongation of the elongate member.
[0031] Within an example and in accordance with an aspect, the
present disclosure provides an articulating-tension washer for an
articulating-tension arrangement to be tensioned against and to
permit articulation relative to an anchor point having a bearing
face extending is a plane and an aperture therethrough, the
arrangement including an elongate member for extending through the
aperture, the elongate member having an elongation extending in a
direction generally transverse to the plane, and the arrangement
including a tightening member operable for providing a tension
force toward the elongate member to pull the elongate member
through the aperture, wherein the articulating-tension washer, to
be retained relative to the bearing face to transmit force between
the tightening member and the anchor point, and the
articulating-tension washer including an arcuate surface for
location away from the bearing face, the arcuate surface extending
in an arc symmetrically across the direction of elongation of the
elongate member.
[0032] An example articulating-tension arrangement 10, in
accordance with an aspect of the present disclosure, is shown
within FIG. 1. Within the shown example, the arrangement 10
includes an elongate member 12, a tightening member 14 and an
articulating-tension washer 16. As shown within FIG. 2, the
elongate member 12 is for extension through an anchor point (e.g.,
an anchor member, support member or the like) 20 and the elongate
member has an elongation extending in a direction generally
transverse (e.g., perpendicular) to the anchor point 20. The
tightening member 14 is operable to provide a tension force,
imparted into the elongate member 12, that tends to pull the
elongate member through an aperture 22 (hidden in FIG. 2, hidden
location indicated by a dashed line) of the anchor point 20. The
force tending to pull the elongate member 12 is the tension force.
The articulating-tension washer 16 is retained at the anchor point
20 to transmit force between the tightening member 14/elongate
member 12 and the anchor point 20. Accordingly, the
articulating-tension washer 16 bears upon the anchor point 20, and
thus the anchor point 20 has a bearing face (e.g., a surface) 24
against which the articulating-tension washer 16.
[0033] The articulating-tension washer 16 has an arcuate (i.e.,
curved) surface 26. The arcuate surface 26 is located to face away
from the anchor point 20 and extends in an arc symmetrically across
(i.e., transverse) the direction of elongation of the elongate
member 12. Such construction and configuration permit secure
tension and articulation traverse, i.e., generally perpendicular,
to the anchor point 20. Binding, and possible associated fatigue
that may occur during loading including cyclical loading, may be
avoided by such construction and configuration. Such aspects, and
other aspects, are discussed further following.
[0034] It is to be appreciated that within the example shown in
FIGS. 1 and 2, the elongate member 12 may be an example male
threaded rod 12 and the tightening member 14 may be an example
female threaded nut 14. The threaded nut 14 mates onto the threaded
rod 12. The threaded nut 14 may be rotated relative to the threaded
rod 12 so that rotational force applied to the threaded nut is
converted into a linear pulling force to provide the tensioning
force within the threaded rod. Such cooperation and operation are
logically well-understood by the person of ordinary skill in the
art.
[0035] It is to be appreciated that the elongate member 12 and the
tightening member 14 may have other constructions/configurations.
As such, the example of the elongate member 12 being a threaded rod
and the tightening member 14 being a threaded nut need not be
limitations upon the present disclosure. It is to be appreciated
that one example material for the elongate member (e.g., the rod)
12 and the tightening member (e.g., the nut) 14 may be metal, such
as steel. Of course, other materials are possible, contemplated and
within the scope of the present disclosure.
[0036] Also, it is to be noted that some additional and optional
example structures are shown within FIGS. 1 and 2. It is to be
appreciated that such additional and optional structures may be
present, absent or replaced with other, different examples
structures. As such, the additional and optional structures need
not be limitations upon the present disclosure. The shown
additional and optional structures are to indicate some examples of
how the information within the present disclosure may be utilized.
The shown additional and optional structures are discussed further
below.
[0037] An example of an additional/optional example structure is a
lock nut 28 (see FIG. 1) added onto the elongate member (e.g., the
rod) 12 and abutting against the tightening member (e.g., the nut)
14. Similar to the tightening member (e.g., the nut) 14, the lock
nut 28 may be a threaded nut. Tightening of the lock nut 28 into
engagement with the tightening member 14 helps prevent further
movement, and specifically a loosening movement, of the tightening
member 14. As mentioned, such is additional/optional, but can be
useful and logical. Also, the function of preventing further
movement, and specifically a loosening movement, of the tightening
member 14 may be accomplished via other additional/optional
structures/mechanisms. For example, a movement prevention coating
may be applied to the threads of the elongate member (e.g., the
rod) 12 and the tightening member (e.g., the nut) 14. As another
example, a retention clip, pin, binder, welding, etc. may be
interconnected between the elongate member (e.g., the rod) 12 and
the tightening member (e.g., the nut) 14. Other options to prevent
further movement, and specifically a loosening movement, of the
tightening member 14 are contemplated and within the scope of the
present disclosure. It is to be appreciated that specifics of
additional/optional structures/mechanisms for prevent further
movement, and specifically a loosening movement, of the tightening
member 14 need not be limitations upon the present disclosure.
Still further, it is to be appreciated that the example of the lock
nut 28 shown with FIG. 1 is understood as showing that the option
of such can occur. Moreover, it is to be appreciated that the
example of the lock nut 28 shown with FIG. 1 is understood as
indicating/showing such to be optionally present or optionally not
present in the any/all of the other figures and/or any/all other
presented examples. For such other figures and/or any/all other
presented examples, the lock nut 28 may not be shown/presented to
simply avoid extra clutter in the figures/discussion. But again to
be clear, the lock nut 28, or other additional/optional
structures/mechanisms for prevent further movement, may be present
for the other figures/examples via this clear indication of such
possibility.
[0038] Focusing upon the articulating-tension washer 16, attention
is directed to FIGS. 3A through 4D, which show some details of an
example of the articulating-tension washer. It is to be noted that
the shown example of the articulating-tension washer 16 is simply
an example and that variations, modifications and the like are
possible, contemplated and within the scope of the present
disclosure.
[0039] The example articulating-tension washer 16 includes a
through aperture 32. The aperture 32 extends completely through
from a first side 34 (see FIG. 3A) to a second side 36 (see FIG.
3B). As is easily seen and appreciated from FIG. 4A, the aperture
32 tapers radially outwardly, in a truncated cone-like shape from
the first side 34 to the second side 36. Specifically, the diameter
of the aperture 32 is relatively smaller adjacent to the first side
34 and is relatively larger adjacent to the second side 36. It is
contemplated that the taper may extend for the entire length of the
aperture 32 or may extend for a majority of the length of the
aperture (e.g., the aperture possibly includes some non-tapered
portion). As such, the aperture 32 include a conic segment. The
conic segment has a taper of angle .alpha.. Within an example,
which is shown in FIG. 4A, the taper angle .alpha. is an 8.degree.
taper as measured from a direction of a center axis 42 of the
aperture 32. So, as seen in FIG. 4A, an upper portion of the conic
extends at an 8.degree. angle up from the direction of the axis 42
(i.e., which is horizontal as viewed in FIG. 4A) and a lower
portion of the conic extends at a taper angle .alpha. (e.g., an
8.degree. angle) down from the direction of the axis (i.e., which
is horizontal as viewed in FIG. 4A). However, it is to be
appreciated that a different taper angle .alpha. (i.e., different
than 8.degree.) is contemplated and within the scope of the present
disclosure.
[0040] It is to be appreciated the respective opening of the
aperture 32 at each of the first and second sides 34, 36 of the
articulating-tension washer 16 is circular in cross-section. The
diameter of the aperture 32 at the first side 34 is smaller than
the diameter of the aperture at the second side 36 (i.e., diameter
is larger at the second side). A taper .beta. (see FIG. 4B) may
provide for the difference in diameter.
[0041] It is to be appreciated that, as viewed in FIGS. 3A, 3B, 4A,
4B, and 4D, the aperture 32 extends along a horizontal direction.
Within these Figures such direction/orientation is identified to
provide ease of reference. As viewed in FIGS. 3A, 3B, 4A, 4B, and
4D, it is to be appreciated that the example articulating-tension
washer 16 has symmetrical structures above and below (i.e.,
vertically) the aperture 32.
[0042] Focusing upon the first side 34 (e.g., see FIG. 3A), the
articulating-tension washer has the arcuate surface 26. The arcuate
surface 26 extends in a convex curve or arc. The aperture 32 is
centered relative to the arcuate surface 26. In general, the
arcuate surface 26 is smooth and may be considered to be a segment
of a cylindrical surface, with a cylinder axis being oriented
horizontally and transverse to the axis 42 of the aperture 32. With
the elongate member 12 (see FIGS. 1 and 2), extending through the
aperture 32, the arcuate surface 26 thus extends in an arc
symmetrically across (i.e., transverse) the direction of elongation
of the elongate member. It is contemplated that the amount of
curvature (e.g., radius of the arc) may be of a different/varied
amount or be changed/adjusted and that such variation/change is
within the scope of the present disclosure and the specific amount
of curvature (e.g., radius of the arc) need not be a specific
limitation upon the present disclosure.
[0043] Focusing upon the second side 36 (e.g., see FIG. 3B), a
significant portion of the second side is a flat, planar surface
46. The planar surface 46 extends in a plane that is transverse
(e.g., perpendicular) to the axis 42 of the aperture 32. The planar
surface 46 extends to the outer periphery of the second side 36.
Within the shown example, the arcuate surface 26 of the first side
34 meets/intersects the planar surface 46 of the second side 36 at
the top (as viewed in FIGS. 3A, 3B, 4A, 4B, and 4D) and the bottom
of the articulating-tension washer 16. A protruding boss 50 extends
outwardly from the plane of the planar surface 46. The boss 50
encircles the aperture 32 that extends through the
articulating-tension washer 16. As such, the boss 50 has the shape
of a short, hollow cylinder.
[0044] It is to be appreciated that the articulating-tension washer
16 may have some additional structural aspects. For example, the
shown example articulating-tension washer 16 includes clipped or
filleted shoulders adjacent each of the top (as viewed in FIGS. 3A,
3B, 4A, 4B, and 4D) and the bottom of the articulating-tension
washer. Also, the shown example articulating-tension washer 16
includes some smoothed/contoured surface junctions. It is to be
appreciated that such additional structural aspects may or may not
be present, may be different, etc., and that such
difference/variation is within contemplated and within the scope of
the present disclosure. It is to be appreciated that one example
material for the articulating-tension washer 16 may be metal, such
as galvanized iron. Of course, other materials are possible,
contemplated and with the scope of the present disclosure.
[0045] Turning now to some functional/operational aspects of the
articulating-tension washer 16, attention is first directed to FIG.
5, in which an example of the vertical anchor point (e.g., anchor
member) 20 is partially shown. The vertical anchor point 20 is at
least part of a system 60 (FIGS. 6 and 7) within which the example
articulating-tension arrangement 10 is utilized/employed. Note that
the vertical anchor point 20 (see FIG. 5) includes a planar segment
64 through which the aperture 22 extends. The bearing face (e.g.,
surface) 24 is on the planar segment 64. Note that the planar
segment 64 extends in a vertical plane and that a center axis of
the aperture 22 is thus transverse (e.g., perpendicular) to the
vertical plane. As such, the axis of the aperture 22 is thus
generally horizontal relative to the vertical anchor point 20 and
with reference to views shown in the Figures.
[0046] Note that the aperture 22 through the planar segment 64 is
sized such that the boss 50 of the articulating-tension washer 16
fits into the aperture 22 through the planar segment 64. The
remainder of the articulating-tension washer 16, and in particular
the planar surface 46 of the articulating-tension washer, does not
fit into the aperture 22 of the anchor point 20. As such, the
planer surface 46 of the articulating-tension washer 16 is
configured to face against and abut against the bearing face (e.g.,
surface) 24 of the planar segment 64 of the anchor point 20. Such
is easily seen in FIG. 7. Also, it is clear that the arcuate
surface 26 of the articulating-tension washer 16 is located away
from the bearing face (e.g., surface) 24 of the planar segment
64.
[0047] It is to be noted that the anchor point 20 may have
other/optional structures. As an example, reinforcing ribs or legs
66 are shown (e.g., see FIG. 5) as extending transversely from the
planar segment 64. Such reinforcing ribs or legs 66 may provide
rigidity or strength. As another example, additional
apertures/holes 68 are shown as extending through the planar
segment. Such additional apertures/holes 68 may be utilized for
connection(s) to other items, members or the like (e.g., 70, see
FIGS. 6 and 7). Such connection(s) may be for a variety of
functions. Such other structures of the anchor point 20 are
contemplated, within the scope of the present disclosure and are
not limitations upon the present disclosure. As an example of such
optional other items, members or the like (e.g., 70), see the
portion of an angled stay 70, which is an optional item, connected
to the anchor point 20 shown within FIGS. 6 and 7. It is to be
appreciated that the presence or absence of such other optional
items, members or the like is not a limitation upon the present
disclosure.
[0048] Please note that the anchor point 20 may be supported,
affixed or the like to something else, such as the ground,
concreate-embedment, other structures, etc. The details of such
support, affixing or the like to can be varied, such variations are
contemplated and within the scope of this disclosure. It is to be
noted that the planar segment 64 may extend in a vertical plane and
the axis of the aperture 22 may be generally horizontal in a use
environment.
[0049] It is to be appreciated that within an example, the
articulating-tension arrangement 10, which includes the
articulating-tension washer 16, is for tensioning (i.e., pulling)
against the anchor point 20. As such and as mentioned, the
articulating-tension arrangement 10 may be part of a system 60.
FIGS. 1, 2, 6 and 7 show some example additional portions of such
an example system 60. Within the shown example, the system 60 is a
cable tension system 60 and the shown example additional portions
are associated with the example cable tension system. Of course,
other example systems are possible, contemplated and thus within
the scope of the present disclosure. Accordingly, the present
disclosure is not limited to only the shown example system.
[0050] Within the shown example, the articulating-tension
arrangement 10 also includes a cable attachment 74. The cable
attachment 74 is secured (e.g., via one or more threaded nuts 76)
onto the elongate member (e.g., the threaded rod) 12. The cable
attachment 74 includes a frame 78 and a spool 80 supported by the
frame via a pin. A cable, or cable holding member(s), 84 may extend
around the spool 80 such that force (e.g., tension force) may be
transmitted from the articulating-tension arrangement 10 (e.g.,
through the elongate member 12, the cable attachment frame 78 and
the spool 80) to the cable holding member/cable 84. The cable may
extend as desired to some other, possible distal location and may
even extend to some other device, structure or the like. The
specifics of the cable extent, other connections, etc. can be
varied. Such variations are contemplated and within the scope of
the present disclosure, and need not be limitations upon the
present disclosure.
[0051] Also within the shown example, the articulating-tension
arrangement 10 includes an optional example flat washer 90 that is
located upon the elongated member (e.g., threaded rod) 12, at a
location that is interposed between the articulating-tension washer
16 and the tightening member (e.g., threaded nut) 14. Specifically,
the flat washer 90 is in engagement with the arcuate surface 26 of
the articulating-tension washer. The flat washer 90 has an aperture
therethrough and two oppositely facing flat sides. Within an
example, the flat washer 90 is made of metal, however other
materials are contemplated and thus within the scope of the present
disclosure. Within the shown example, the example flat washer 90 is
shown as having a polygonal (e.g., square) outer periphery.
However, it is to be appreciated that other outer periphery shapes
(e.g., non-square polygonal, round, ovoid, etc.) are possible,
contemplated and within the scope of the present disclosure.
Accordingly, the present disclosure is not limited to the specifics
of the flat washer 90.
[0052] The flat washer 90 is to transmit force between the
tightening member (e.g., threaded nut) 14 and the
articulating-tension washer 16. Also, the flat washer 90 may
provide a function of permitting a smooth, or at least relatively
smooth/smoother, pivoting/tilting motion of the flat washer 90 upon
the arcuate surface 26 of the articulating-tension washer 16. Such
pivoting/tilting motion may occur during a motion, and possibly a
specific articulation (i.e., pivoting) motion, of the elongate
member (e.g., threaded rod) 12 relative to the articulating-tension
washer 16 and the anchor point 20 to which the articulating-tension
washer is engaged and is bearing upon. Such connection/movement of
the elongate member 12 and the articulating-tension washer 16 is
articulation (e.g., connected so as to permit motion).
[0053] It is to be appreciated that the presence of the flat washer
90 is shown within the presented example and is logical. However,
it is to be appreciated that it is contemplated that within some
examples it may be possible to omit the flat washer 90. For such
examples, the tightening member (i.e., threaded nut) 14 could
engage and bear directly upon the articulating-tension washer 16.
It is contemplated that such examples possibly may not operate as
efficiently as examples that include the flat washer 90. Also, such
examples in which the flat washer 90 is not present may employ a
different tightening member (e.g., threaded nut) 14 than as shown
within the Figures. Some possible examples of such a different
tightening member 14 may be a larger periphery tightening member, a
tightening member that includes a collar bushing, or the like. So,
the option of the presence of the flat washer 90 and the option of
the absence of the flat washer 90 are both within the scope of the
present disclosure. It is also to be appreciated that the flat
washer 90 may be provided as an optional multi-component
arrangement/device (e.g., stacked plural flat washers). Such
options are also within the scope of the present disclosure.
[0054] FIG. 7 shows that the amount of force, and specifically
tension force, can be adjusted via tighten/loosen the tightening
member 14. Specifically, the horizontal double-headed arrowhead
indicates adjustment movement of the elongate member 12 relative to
the anchor point 20. Movement of the elongate member 12 toward the
right, as viewed within FIG. 7, via operation (i.e., turning to
tighten) of the tightening member 14 increases the tension force.
Movement of the elongate member 12 toward the left, as viewed
within FIG. 7, via operation (i.e., turning to loosen) of the
tightening member 14 decreases the tension force.
[0055] FIG. 7 also indicates that the tension direction (a pulling
force toward the right as viewed in FIG. 7) is transverse (e.g.,
perpendicular) to the planar extend of the anchor point 20. Also,
within the orientation of FIG. 7, the figure shows that the tension
direction is horizontal.
[0056] It is to be appreciated that at least one, and possibly more
than one, condition, event or the like may impose a vertical (as
viewed in FIG. 7) force upon a distal end (i.e., the end at which
the cable attachment 74 is located) of the articulating-tension
arrangement 10. The vertical force may be either upward or
downward. See the vertical double-headed arrowhead at the location
of the cable attachment 74.
[0057] In accordance with at least one aspect of the present
disclosure, the articulating-tension arrangement 10 may
accommodate/accept such force. For such, it is contemplated that
the elongate member 12 may tilt or pivot. Moreover, in accordance
with at least one aspect of the present disclosure, the
articulating-tension arrangement 10 may accommodate/accept such
force without issues such as binding, wear, or the like. Also, in
accordance with an aspect of the present disclosure, such helps
avoid unintended loosening of the tightening member 14.
[0058] In accordance with at least one aspect of the present
disclosure, the elongate member 12 is permitted to pivot relative
to the articulating-tension washer 16 and the anchor point 20
against which the articulating-tension washer bears. With reference
to at least FIG. 7, see that the elongate member 12 has room to
pivot within the conic shape of the aperture 32 within the
articulating-tension washer 16. Also, with reference to at least
FIGS. 7 and 8, see that the arcuate surface 26 on the first side 34
of the articulating-tension washer 16 permits movement (e.g.,
rocking or pivoting) along the arcuate surface. Such permitted
movement may be the by the flat washer 90, if present, and/or the
tightening member 14. Such, permitted movement (e.g., rocking) on
the arcuate surface 26 avoids binding and/or fatigue occurring
upon/within parts of the articulating-tension arrangement 10.
[0059] It is to be appreciated that the permitted movement is
equally permitted both upward (as viewed within FIGS. 7 and 8) and
downward. Such is due to the construction/configuration of the
articulating-tension washer 16, and specifically the arcuate
surface 26 being symmetrical, about (i.e., above and below) the
axis of the aperture 32 in the vertical direction. See also FIG.
4A, which shows the conic taper of the aperture 32 being both above
the axis 42 and bellow the axis, and also the curve of the arcuate
surface 26 being both above the axis 42 and below the axis 42. The
portion of the arcuate surface 26 above the axis 42 could be
considered to be a mirror-image of the portion of the arcuate
surface 26 below the axis 42.
[0060] Attention is directed to FIG. 8 which shows three possible
pivot positions of the elongate member 12 relative to the
articulating-tension washer 16. Note that the articulating-tension
washer 16 remains stationary (i.e., as would occur with the
protruding boss 50 within the aperture 22 of the anchor point 20,
and the planar surface 46 bearing upon the planar segment 64 of the
anchor, see FIGS. 5-7). Within the shown example of FIG. 8, the
shown middle position occurs with the elongate member 12 aligned
with the axis 42 of the aperture 32 of the articulating-tension
washer 16.
[0061] The shown "left side tipped lower" position (as shown in
FIG. 8, which is shown in phantom and indicated with reference
numerals provided with the addition of "'" (prime)) is to provide
an appreciation that the position is a possible position that
occurs with the elongate member 12 pivoted "left side down"
relative to the axis of the aperture of the articulating-tension
washer 16. Note that the flat washer 90' and the tightening member
14' are shown in a rocked/pivoted position up the arcuate surface
26 of the articulating-tension washer 16. Note that the
rocking/pivoting of the flat washer 90 and the tightening member 14
is at a location away from the bearing face 24 of the anchor point
20. So, the articulating-tension washer 16 allows the elongate
member 12 to "articulate."
[0062] Within one example (e.g., see FIG. 8) regarding the movement
or articulation of the elongate member 12, the angle of pivot is
8.degree. from the axis of the aperture of the articulating-tension
washer 16. It is to be recalled, that an example of the
articulating-tension washer 16 included an example conic taper of
8.degree. for the aperture of articulating-tension washer.
Accordingly, the shown "left side tipped lower" position would be a
maximum downward permitted pivoting for such example.
[0063] The shown "left side tipped higher" position (as shown in
FIG. 8, which is shown in phantom and indicated with reference
numerals provided with the addition of "''" (double prime)) occurs
with the elongate member 12 pivoted up relative to the axis of the
aperture of the articulating-tension washer 16. Within one example,
the angle of pivot is 8.degree. from the axis of the aperture of
the articulating-tension washer. Note that the flat washer 90'' and
the tightening member 14'' are shown in a rocked/pivoted position
down the arcuate surface 26 of the articulating-tension washer 16.
So, the articulating-tension washer 16 allows the elongate member
12 to "articulate."
[0064] It is to be recalled, that an example of the
articulating-tension washer included a conic taper of 8.degree. for
the aperture of articulating-tension washer 16. Accordingly, the
shown "left side tipped higher" position would be a maximum upward
permitted pivoting for such example.
[0065] It is to be appreciated that the angle of pivot may be
different (i.e., other than 8.degree.). Such, different angles of
pivot are within the scope of the present disclosure. In other
words, the angle of pivot being 8.degree. is only an example and
need not be a specific limitation upon the present disclosure.
[0066] It is to be appreciated that the discussed example is
presented in terms of the articulating-tension washer 16 having the
arcuate surface 26 oriented with the arc in a vertical plane, and
thus the permitted pivoting of the elongate member 12 is within a
vertical plane. Such orientation/function may be useful for load
force/tension force that is horizontal. It is to be appreciated
that a different orientation of the articulating-tension washer 16
may be selected/utilized. Attention is directed to FIG. 2, which
shows that any orientation (i.e., any rotational position within
360.degree. of rotation availability) is possible and contemplated.
Thus, such is within the scope of the present disclosure. Such
selection may be useful to accommodate particular directional
forces that may be imposed upon the elongate member 12, and thus
accommodate particular directional pivot movements that may be
occur for the elongate member.
[0067] Of course, methods of making the articulating-tension
arrangement and/or the articulating-tension washer, and portions
thereof, and methods of utilizing the articulating-tension
arrangement and/or the articulating-tension washer, and portions
thereof, are contemplated and within the scope of the present
disclosure.
