Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application is a non-provisional utility
application claiming priority to U.S. Provisional Patent
Application No. 60/602,263 titled "Exercise Equipment" filed Aug.
16, 2004, which is hereby incorporated by reference herein.
FIELD OF THE INVENTIONS
[0002] Aspects of the present invention involve exercise equipment,
and more particularly involve exercise equipment, such as a
treadmill, with a four wheel combination elevation and transport
assembly, a dual power plug arrangement, an arm support upright
assembly providing structural and aesthetic flexibility, and a
diagnostic light arrangement, alone or in combinations.
BACKGROUND
[0003] The health benefits of regular exercise are well known. Many
different types of exercise equipment have been developed over time
to facilitate exercise as well as medical rehabilitation. One
example of a successful type of exercise equipment is the
treadmill. Conventionally, a treadmill provides a moving surface,
typically a belt arranged between rollers, that moves at a
specified rate. The user walks or runs on the moving surface.
Besides having well developed moving surface mechanics to provide a
great user experience, it is important to also present a treadmill
that is aesthetically pleasing, easy to move about a home, health
club, rehabilitation facility or the like, and able to be arranged
in a home or other area as a user desires.
[0004] Conventional treadmills typically include a pair of front
wheels that allow a user to pick up the back of the treadmill and
roll the treadmill to a desired location. Treadmills that
incorporate only the pair of front wheels force the user to support
a substantial amount of the weight of the treadmill making movement
of the treadmill strenuous. Therefore, there is a need in the art
for a treadmill that allows for efficient and reliable movement of
the treadmill.
[0005] To drive the tread belt or other moving surface, typical
conventional treadmills include a motor and drive electronics. Most
conventional treadmills also include other electronics, such as to
provide a customized workout or for selecting from existing
preprogrammed workout routines. Conventional treadmills typically
provide one power outlet where a power cord is connected and may be
plugged into a conventional wall outlet. The power outlet is
typically provided at the front or rear of the treadmill. Many
spaces are not tailored for placement of a treadmill, and wall
plugs are inconveniently located in relation to the desired
placement of a treadmill. In these situations, it is often
necessary to add extension cords in order to reach a wall outlet.
Oftentimes, the treadmill power outlet will be on a side of the
treadmill away from the desired outlet; thus, causing the cord to
be stretched around the treadmill to reach the outlet. Therefore,
there is a need in the art to provide for alternative or additional
power outlets on the treadmill to provide for alternative power
cord location.
[0006] As with any electromechanical equipment, exercise equipment,
whether a treadmill or other form of exercise equipment, requires
periodic maintenance and sometimes malfunctions. In an effort to
remind users of maintenance and expedite diagnosis of malfunctions,
diagnostic light arrangements have been developed. The lights are
illuminated in various combinations to identify various issues.
However, conventional treadmills typically arrange the lights
adjacent or on the various internal electronics, which are placed
under covers. As such, the cover must be removed to view the
lights. Therefore, there is a need in the art to provide for
diagnostic lights that viewable without removal of covers or
otherwise easily viewed by a user.
[0007] Various aspects of the present invention discussed in detail
below address these and other concerns with conventional
treadmills.

supported on the panel, but may be arranged on some other portion
of the exercise apparatus so that they are visible without having
to remove the shroud. It is also possible to arrange the diagnostic
lights in such a manner that they are only visible from some
angles. For example, the diagnostic lights might be mounted on a
panel located under below a shroud, but visible from the side of
the device as they are arranged below a lower edge of the
shroud.
[0010] Another aspect of the invention involves an exercise
apparatus, such as a treadmill, elliptical, exercise bicycle, stair

502. A brace 1004 extends between each wheel support bracket 302,
802 to provide lateral stabilization to the wheel brackets 302, 802
and rear wheels 306, 502 when engaged with the floor. The front of
the wheel support brackets 302, 802 are fixed to a pivot rod 902
that extends between left pivot support 904 and right pivot support
1002 connected to the bottom of left and right frame rail 104, 102
respectively. The pivot rod 902 is adapted to pivot or rotate
within the pivot supports 904, 1002. Being pivotally supported in
the wheel support brackets 302, 802, the rear wheels 306, 502 are
adapted to pivot downwardly from the frame 101 to lift the front of
the treadmill 100. Pivoting downward in such a manner and raising
the front of the treadmill 100 causes an increase in the angle (or
slope) of the tread belt 106 to simulating walking or running
uphill. The rear wheels 306, 502 in their most downwardly pivoted
orientation, as shown in FIG. 8, may also form a four wheel
transport assembly 132. The user lifts up on the rear of the device
causing the treadmill 100 to pivot about the rear wheels 306, 502
downwardly to engage the front wheels 120, 122, as shown in FIG. 8.
Arranged in such a manner, all four wheels 306, 502, 120, 122 are
in engagement with the ground which allows easier movement of the
treadmill 100 about a room.
[0049] In some conventional exercise equipment, only the front two
wheels 120, 122 are provided. If the transport assembly 132 is
withdrawn, the user may still move the treadmill 100 by only
engaging the front two wheels 120, 122, as in conventional
treadmills. With the transport assembly 132 extended, the transport
assembly 132 bears the weight of the treadmill 100, rather than the
user. Preferably, the transport assembly 132 is arranged so that
the center of gravity of the treadmill 100, in the elevated
position, is roughly centered above the assembly 132 between the
front 120, 122 and rear wheels 306, 502. In this way, the transport
assembly 132 bears most of the weight in the transport position
(after the user has lifted the treadmill 100 to engage the four
wheels 306, 502, 120, 122).
[0050] The rear wheels 306, 502 are pivoted downwardly through a
pivot bracket 808 connected with a deck elevation motor 208. The
pivot bracket 808 is generally triangular shaped with one point of
the triangular shape being fixed to the front pivot rod 902. A
second rearward point on the triangle defines a concave recess
adapted to engage the brace 1004 extending between the wheel
support brackets 302, 802. The pivot bracket 808 is not fixed to
the rear brace 1004 but rather merely touches the rear brace 1004
so that when the assembly 132 is rotated downwardly, rotational
movement with respect to the pivot bracket 808 may occur unimpeded.
It is possible to lubricate the interface between the pivot bracket
808 and the brace 1004, through liquid lubricants or structural
interfaces that reduce the coefficient of friction.
[0051] The top point on the triangular pivot support bracket 808
pivotally supports a screw collar 906. The deck elevation motor 208
is arranged to drive a motor screw 910. The motor screw 910 extends
through the screw collar 906. As is known in the art, the motor
screw 910 defines threads adapted to engage the threads within the
screw collar 906. Thus, by rotation of the motor screw 910, the
screw collar 906 is driven forwardly or rearwardly depending on the
rotation direction of the screw 910. Driving the screw 910
rearwardly causes the pivot bracket 808 to rotate downwardly about
the front pivot, rotating downwardly in such a manner presses down
on the transverse brace 1004 which in turn causes the rear wheels
306, 502 to move downwardly from the rear to elevate the front of
the treadmill 100. In contrast, when the screw 910 is rotated in
the opposite direction the screw collar 906 is pulled forwardly
allowing the deck to settle back down into its flat position. To
facilitate such movement, the screw collar 906 is pivotally
supported on the pivot bracket 808 and the motor drive screw 910 is
also pivotally supported. Such pivotal support is necessary because
the angle and elevation of the screw collar 906 changes as the
pivot bracket 808 rotates downward or upward about the front pivot
rod 902.
[0052] Besides four wheels, it is possible to use rollers, one
front wheel and two rear, or two front and one rear, or other
combinations. Further, it is possible to rotatably support the
front wheels 120, 122 or rear wheels 306, 502 to ease turning the
treadmill 100 when it is being moved.
[0053] C. Upright
[0054] FIG. 12 is a section view taken along line 12-12 of FIG. 1.
FIG. 12 illustrates some of the inner components of the upright
construction. FIG. 13 illustrates the treadmill 100 of FIG. 1 and
others with a section taken to illustrate the inner structure of
the uprights. FIG. 14 is a close-up view of the right upright 108
from the perspective of the section of FIG. 13. FIG. 15 is an
isometric view similar to FIG. 14 but orienting the upright in such
a manner as to see downward within the upright construction. FIG.
16 is a close-up of FIG. 13 illustrating the left upright 110 and
the inside view of the upright. FIG. 17 is a section view taken
along line 17-17 of FIG. 1 through the left upright 110. Referring
to FIGS. 12-17, the upright assembly of a treadmill or other
exercise apparatus conforming to the present invention generally
comprises a right metal upright standing member 1204 and a left
upright standing member 1612 and an assembly shrouding a portion of
the metal inner frame members 1204, 1612. The combination of the
metal inner members 1204, 1612 and outer shroud, which may be a
molded polymer, provides both a structurally sound upright
construction and the flexibility to construct various aesthetically
pleasing shapes in a cost effective manner.
[0055] The right inner member 1204 generally defines an elongate
upstanding three sided piece. The right inner member 1204 (and
upright generally) extends upwardly from the right frame rail 102.
The right inner member 1204 has a side wall 1502, a forward wall
1206 and a rearward wall 1208, but does not define a second side
wall. As such, as best shown in FIG. 15, a cross-section through
the right inner member 1204 defines a generally U-shaped. Referring
now to FIG. 17, a section through the left inner member 1612 is
provided to illustrate the side wall 1602 configuration of the left
inner member 1612. Note, the left and right uprights 110 and 108,
respectively, are substantially mirror images of each other; thus,
discussion with respect to one upright is equally applicable to the
other upright. As seen in FIG. 17, the side wall 1602 defines a
downwardly extending mounting tongue 1704. The mounting tongue 1704
includes four apertures 1706-1, 1706-2, 1706-3 and 17064 adapted to
receive mounting bolts (not shown). Referring now to FIG. 12, it
can be seen that the right frame rail 102 includes four mounting
bosses 1202-1, 1202-2, 1202-3 and 1202-4 arranged to receive the
mounting tongue bolts (not shown). Thus, the right metal upright
1204 may be fixed to the frame 101 by threading four bolts through
the corresponding tongue apertures into the threaded bosses 1202-1,
1202-2, 1202-3 and 1202-4 provided in the right frame rail 102. For
added stability and rigidity, an X flange pattern is provided
between the upright bosses 1202-1, 1202-2, 1202-3 and 1202-4. As
best shown in FIG. 12, the front wall 1206 and rear wall 1208 of
the right inner member 1204 include a cutout portion adapted to
engage the top of the right frame rail 102.
[0056] Referring to FIG. 1, a right shroud 138 includes an upper
portion 136 and a lower portion 140. The upper portion 136 of the
right shroud 138 generally defines an inverted U-shaped arrangement
with a front portion of the U covering the front wall 1206 of the
right inner member 1204, a rear portion of the U covering the rear
wall 1208 of the right inner member 1204 and the concave portion of
the U extending across the top of the right upright member 108 and
further including a partially cylindrical channel adapted to
receive the right upper handrail 112. Note the upper portion 136 of
the right shroud 138 defines an upside down U-shaped configuration.
In contrast, the lower portion 140 of the right shroud 138 defines
an upstanding U-shaped configuration. The rear portion or leg of
the U is adapted to engage with the corresponding rear portion of
the upper portion 136 of the right shroud 138 and further is
arranged over the rear wall 1208 of the right inner member 1204.
The front upstanding portion of the lower portion 140 of the right
shroud 138 is arranged over the front wall 1206 of the right inner
member 1204 and is adapted to cooperate with the front leg of the
upper portion 136 of the right shroud 138. The combination of the
upper portion 136 and lower portion 140 of the right shroud 138
define an elongate somewhat elliptical opening exposing a part of
the side wall 1502 of the right inner member 1204.
[0057] As best shown in FIG. 16, the left upright 110 has a left
shroud 142. The left shroud 142 includes an upper portion 146
(shown in FIG. 1) and a lower portion 144. The front and rear legs
of upper 146 and lower portions 144 of the left shroud 142 define a
generally J-shaped cross-section. The short or hook portion of
J-shapes 1610 and 1608 engage the side wall 1602 of the left inner
member 1612 adjacent a front wall 1604 (for the front legs) and
adjacent a rear wall 1606 (for the rear legs). The long portion of
the J-shapes 1610 and 1608 is arranged outwardly of the front 1604
and rear walls 1606 of the left inner member 1612, respectively.
Generally speaking, the elongate portion of the J-shapes 1610 and
1608 which corresponds with the forward and rearward portions of
the left shroud 142, extend generally parallel to the front wall
1604 and rear wall 1606 of the left inner member 1612,
respectively. Along the forward and rearward portions of the left
shroud 142 a series of bosses 1614 are molded in the left shroud
142 to provide an attachment point for a back plate 1616. As shown
in the various Figures, a back plate 1616 extends along the length
of the left upright 110 from an area adjacent its lower end to an
area adjacent its upper end. The back plate 1616 defines a series
of apertures (not visible) adapted to receive screws to fix the
back plate 1616 to the bosses 1614 defined in the left shroud 142.
The back plate 1616 is generally arranged to cover the otherwise
opened inside portion of the left inner member 1612 and otherwise
opened portions of the inside part of the left shroud 142. In one
particular arrangement, the back plate 1616 is recessed between the
elongate portions of the J-shapes 1610 and 1608. Arranged in such a
manner, the back plate 1616 defines a common plane with the end of
each portion of the each J-shaped elongate portions 1610 and 1608
of the left shroud 142 and the back plate 1616. Note again, the
left and right uprights 110 and 108, respectively, are
substantially mirror images of each other; thus, discussion with
respect to one upright is equally applicable to the other
upright.
[0058] Referring to FIG. 12, a shroud mounting bracket 1210 is
welded to the upper portion of the inner right frame rail 102. The
shroud mounting bracket 1210 is generally L-shaped with one portion
of the L being welded to the upper portion of the right frame rail
102 and the other portion of the L extending upwardly from the
right frame rail 102 and adapted to receive a bolt (not shown)
affixing the lower portion 140 of the right shroud 138 to the
mounting bracket 1210. Still referring to FIG. 12, it can be seen
that the upper portion 136 of the right shroud 138 defines a
setback 1212 at its lower rim. The setback 1212 is adapted to
receive the upper rim of the lower portion 140 of the right shroud
138. Providing a setback in such a manner helps to facilitate
assembly of the right upright 108 by providing a positive placement
of the upper portion 136 with respect to the lower portion 140 and
also provides a smooth aesthetically pleasing interface between the
upper 136 and lower portions 140 of the right shroud 138. The lower
portion 140 of the right shroud 138 also defines a forwardly
extending piece that is adapted to cooperate with other decorative
cover components of the treadmill 100. Further, the lower portion
140 of the right shroud 138 defines a rearwardly extending portion
adapted to cooperate with other decorative covers over the right
frame rail 102.
[0059] D. Power Plugs and Associated Electronics
[0060] FIG. 18 is a front view of the treadmill 100 of FIG. 1 and
others employing a dual power plug configuration, in accordance
with one aspect of the present invention. To more clearly view the
power plug 508 and associated power plug selection switch 506, a
front decorative cover 1902 of the treadmill 100 is removed. In
contrast, FIG. 19 is also a front view of the treadmill 100
employing a dual power plug configuration, but with the front
decorative cover 1902 in place. As can be seen, a window 1904 is
supplied in the front decorative cover 1902 to provide access to
both the plug 508 and the plug selection switch 506. FIG. 20
(similar to FIG. 7) is a bottom view of the treadmill 100,
illustrating the rear power plug 704. The switch 506 shown in FIGS.
18 and 19 allows a user to select between the front plug 508 and
the rear plug 704. In one position of the switch 506, the front
plug 508 is activated and in a second position of the switch 506
the rear plug 704 is activated. In such a manner a power cord (not
shown) coupled with an AC inlet may be connected with the front
plug 508 or the rear plug 704. By appropriately selecting the
switch 506, power is routed to the various electronics of the
treadmill 100 through the front plug 508 or rear plug 704,
whichever is connected with an AC power source.
[0061] The location of the plugs 508 and 704 and switch 506 is
selected to facilitate the front of the treadmill 100 to be
arranged generally facing a power supply, i.e., with the front of
the treadmill 100 facing an AC power source, or with the rear of
the treadmill 100 facing the power source. In a frontward facing
orientation, the front plug 508 would be used and the associated
power cord may be discreetly located between the front of the
machine and the AC power source. In contrast, if the rear of the
machine is arranged to face the AC power source, the power cord may
be discreetly arranged and utilize the rear plug 704. Without such
a dual plug arrangement, to reorient the device would require in
one orientation or the other the cord to be serpentinely routed
along the entire length of the treadmill 100 to get to the power
source. Stated another way, without a front plug 508, but in a
situation where the user would like to orient the front of the
treadmill 100 to face the power supply, a cord would have to be
routed between the rear plug 704 along the length of the treadmill
100 to the front of the treadmill 100 and to the AC power source.
With such power cord arrangements, which is typical in prior art
treadmills, the cord oftentimes is in the way of the user. Further,
a much longer cord must be supplied with the treadmill or extension
cords used to provide access to the power plug in any particular
arrangement.
[0062] FIG. 21A is a block diagram illustrating the dual power plug
arrangement, the switch and other electronics. More particularly,
each power plug 508 and 704 is wired to a switch 506. In one
particular embodiment, the switch 506 is a double-pull,
double-throw ("DPDT") type switch with center off. In the
arrangement of the switch 506 shown in FIG. 21A, power is not
supplied from either power plug 508, 704, i.e., the switch 506 is
in the OFF state. FIG. 21B illustrates the switch 506 oriented to
select the rear plug 704, and FIG. 21C illustrates the switch 506
arranged to select the front plug 508. When the rear plug 704 is
selected, the front plug 508 is completely isolated from power.
Similarly, when the front plug 508 is activated, the rear plug 704
is completely isolated from power. Other switching configurations
may be employed in a treadmill employing a plurality of plugs.
Additionally, multiple switch configurations may be employed. As
such, a switch may be separately arranged at the rear plug 704 and
the front plug 508 to activate each plug independently.
[0063] Regardless of the switching configuration, when either plug
508, 704 is activated power is supplied through a conventional
circuit breaker 2102 and a line filter 2104 to the control board
218 of the treadmill 100. The control board 218 comprises an
elevation control board and a motor control board and includes a
communication and power path to the treadmill deck elevation motor
208 and the treadmill belt drive motor 206. The control board 218
also includes a communication path to the console 118 and control
inputs 124. Finally, the control board 218 includes a CE Harmonics
filter 2106 arrangement. Conventional control signals for the
treadmill deck elevation motor 208 and the treadmill belt motor 206
are supplied through the console 118 or control inputs 124. As
such, a user may adjust the treadmill deck elevation and the
treadmill belt speed and also turn the treadmill 100 "on" through
various switches and inputs on the console 118 or control inputs
124 to the control board 218. Embodiments of the present invention
may include more than two plugs and as such may include a plurality
of plugs and the appropriate switching arrangement to select the
various plugs. The power inlets may be 15 or 20 amp rated and
conforming to IEC320 specifications, in embodiments conforming to
the present invention. Besides manually activated switches, it is
also possible to use a relay or other switching mechanism in
embodiments of the present invention.
[0064] E. Diagnostic Lights
[0065] FIG. 22 is a partial isometric view of the front of a
treadmill 100 conforming to the present invention. The front of the
treadmill 100 includes a front cover 1902 arranged over the drive
motor 206, elevation motor 208 and other adjacent components.
Arranged on the front cover 1902 is a plurality of diagnostic
lights 134-1, 134-2 to 134-R, which may be light emitting diodes.
Each diagnostic light 134-1, 134-2 to 134-R is coupled or in
electrical communication with the motor control board and the
elevation control board, located in the control board 218, and also
the control console 124 and the console 118 electronics. The
elevation control board and motor control board located in the
control board 218 are arranged under the decorative cover 1902 and
provide the control electronics for the motors 206, 208. Each board
includes various communication pathways to the other boards as
needed and to the diagnostic lights 134-1, 134-2 to 134-R as
needed.
[0066] Conventionally, diagnostic lights are not visible outside
the treadmill decorative housing, or any exercise device shrouding.
As such, when a treadmill is functioning or malfunctioning as the
case may be, it is necessary to remove some portion of the
shrouding in order to view the diagnostic lights. Note, the covers
while being partially decorative in nature are also functional by
providing protection for the underlying components and performing
other functions as well.
[0067] Generally speaking, various combinations of the diagnostic
lights 134-1, 134-2 to 134-R convey to a knowledgeable viewer
status information of the motor control subsystem and other
electronic subsystems of the treadmill 100. In a simple
arrangement, each diagnostic light 134-1, 134-2 to 134-R is
associated with one diagnostic status. In a more complicated or
sophisticated arrangement, the lights 134-1, 134-2 to 134-R may be
lit in various combinations to display a greater amount of
diagnostic and general status information. Further, multi-color
lights may be used where various light combination indicate status.
For example, a red and green light emitting diode may be employed,
where red indicates a malfunction and green indicates proper
function.
[0068] In one particular implementation, one of the diagnostic
lights 134-1, 134-2 to 134-R is associated with a grade up status
indicator, one of the diagnostic lights 134-1, 134-2 to 134-R is
associated with a grade down status indicator, one of the
diagnostic lights 134-1, 134-2 to 134-R is associated with a speed
movement status indicator, one of the diagnostic lights 134-1,
134-2 to 134-R is associated with a speed control pulse width
modulator status indicator, and one of the diagnostic lights 134-1,
134-2 to 134-R is associated with a belt enable indicator. The
grade up status indicator is driven from the command relay that
engages grade up motor windings in the elevation motor 208.
Generally speaking, the grade up status light illuminates when the
control board 218 sends a signal to the elevation motor 208 to move
upward. As such, if the grade up indicator does not illuminate,
then the control board 218 is not sending the commanded voltage to
the elevation motor 208.
[0069] Similar to the grade up diagnostic light, the grade down
diagnostic light is illuminated when the control board 218 sends a
signal from the command relay that engages the grade down motor
windings of the elevation motor 208. Thus, if the elevation motor
208 is receiving the grade down command then the grade down
diagnostic light will illuminate. Conversely, if the control board
218 is sending the signal, but it is not being received, then the
grade down diagnostic light will not illuminate.
[0070] The speed movement status light is set to flash with every
turn of the front roller 710 showing that front roller movement
sensor (not shown) is functioning correctly. Note, front roller
movement sensors are well known in the art of treadmill control. If
the speed movement LED does not flash then various problems might
be indicated, such as the roller is not moving, the connection
between the front roller sensor and the diagnostic light is broken,
or a sensor or positioning problem, amongst others.
[0071] The speed control diagnostic light's intensity is directly
related to speed, the faster the tread belt 106 is commanded to go,
the brighter the LED's output. For example, if there is no
intensity increase when an increase in speed request is sent, it
might indicate that the motor control simply is not receiving the
speed control signal. This is not the actual motor drive control
signal, but the console (118 or 124?) generated target speed
value.
[0072] The belt enable diagnostic light is illuminated as a
function of whether power is being transferred to the belt drive
circuitry. If the belt enable diagnostic light is illuminated, this
indicates that the motor control assembly has received the belt
start command and is attempting to apply power to the switching
control circuitry.
[0073] It is also possible to illuminate the diagnostic/status
lights as a function of the communication path between the control
inputs 118 and the corresponding motor control boards located in
the upper and lower portions of the treadmill 100, respectively. It
is also possible to illuminate the diagnostic lights as a function
of deck wear replacement status, lubrication schedules, service
intervals, etc. Such diagnostic light illuminations may be done
throughout operation of the treadmill 100 or at any time there is
power to the treadmill 100. For example, certain diagnostic status
indicators may be illuminated only at startup or shutdown of the
treadmill 100 whereas other diagnostic illuminations may be
continued throughout use of the treadmill 100.
[0074] Although preferred embodiments of this invention have been
described above with a certain degree of particularity, those
skilled in the art could make numerous alterations to the disclosed
embodiments without departing from the spirit or scope of this
invention. All directional references (e.g., upper, lower, upward,

to "ends" having a particular characteristic and/or being connected
to another part. However, those skilled in the art will recognize
that the present invention is not limited to components which
terminate immediately beyond their points of connection with other
parts. Thus, the term "end" should be interpreted broadly, in a
manner that includes areas adjacent, rearward, forward of, or
otherwise near the terminus of a particular element, link,
component, member or the like. In methodologies directly or
indirectly set forth herein, various steps and operations are
described in one possible order of operation, but those skilled in
the art will recognize that steps and operations may be rearranged,
replaced, or eliminated without necessarily departing from the
spirit and scope of the present invention. It is intended that all
matter contained in the above description or shown in the
accompanying drawings shall be interpreted as illustrative only and
not limiting. Changes in detail or structure may be made without
departing from the spirit of the invention as defined in the
appended claims.
[0076] It will be recognized by those skilled in the art, that
various elements discussed with reference to the various
embodiments may be interchanged to create entirely new embodiments
coming within the scope of the present invention. It is intended
that all matter contained in the above description or shown in the
accompanying drawings shall be interpreted as illustrative only and
not limiting. Changes in detail or structure may be made without
