DETAILED DESCRIPTION
[0026] This disclosure generally relates to offset casters,
computing device supports, systems for supporting a computing
device, and methods of use. More particularly, this disclosure
generally relates to offset casters that may be used to alter the
center of gravity of a support and/or may provide a brake that
maintains its position relative to the support.
[0027] In at least one implementation, an offset caster may alter
the center of gravity of a computing device support by 25.0
millimeters (mm). In at least one implementation, an offset caster
may alter the center of gravity of a computing device support by
more than 1% of the distance between two wheels. In at least one
implementation, an offset caster may provide access to a brake
regardless of wheel position. In at least one implementation, an
offset caster may provide a brake that may limit caster rotation
and/or wheel rotation. In at least one implementation, an offset
caster may provide a brake that may engage with a single push of an
actuator and may disengage with a single push of the actuator.
[0028] FIG. 1 is an isometric view of an implementation of a
computing device support 100. FIG. 2 is a front view of the
implementation of the computing device support 100 of FIG. 1. FIG.
3 is a top view of the implementation of the computing device
support 100 of FIG. 1.
[0029] Referring generally to FIGS. 1-3, the computing device
support 100 may include a mount 102. The mount 102 may receive a
computing device. Computing devices may include monitors, displays,
smart televisions, tablet computers, hybrid computers, laptops, or
other computing devices. In implementations where the mount 102 has
received a computing device, a system may be formed.
[0030] The computing device support 100 may include a plurality of
legs 104. As shown, the computing device support 100 includes four
legs 104-1, 104-2, 104-3, 104-4. The legs 104 may provide support
to the mount 102. The computing device support 100 may include
front legs (e.g., legs 104-1, 104-2) and rear legs (e.g., legs
104-3, 104-4).
[0031] As shown, the legs 104 may form an A-frame type easel. In
other words, the pairs of legs 104 (e.g., one front leg and one
rear leg) may be connected at one end. In other implementations,
the legs 104 may be otherwise arranged. In some implementations,
the rear legs may be shorter than the front legs and/or may connect
at a location along the length of the front leg. For example, the
rear legs may be connected near the middle of the front legs.
[0032] Referring briefly to FIG. 4-1, a side view of the
implementation of the computing device support 100 of FIG. 1, the
legs 104 may form an angle 105 between them. In some
implementations, the angle 105 may be in a range having an upper
value, a lower value, or upper and lower values including any of 15
degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40
degrees, or any value therebetween. For example, the angle 105 may
be 15 degrees. In other examples, the angle 105 may be less than 40
degrees. In further examples, the angle 105 may be greater than 20
degrees. In yet other examples, the angle 105 may be in a range of
15 degrees to 40 degrees. In yet further examples, the angle 105
may be in a range of 20 degrees to 35 degrees.
[0033] Referring back to FIGS. 1-3, the computing device support
100 may include storage 106. The storage 106 may be connected to
one or more legs 104. As shown, the storage 106 is connected to
each leg 104. The storage 106 may be used to support one or more
components of a computing device. For example, the processor and/or
memory of a computing device may be supported by the storage 106
and connected to a monitor. In another example, a keyboard, a
mouse, a digital pen, other accessories, or combinations thereof
may be supported by the storage 106.
[0034] The computing device support 100 may include one or more
casters (e.g., casters 110, 120). The computing device support 100
may include one or more types of casters. As shown, the rear legs
(e.g., legs 104-3, 104-4) are connected to casters 110 and the
front legs (e.g., legs 104-1, 104-2) are connected to offset
casters 120. In at least one implementation, the computing device
support 100 includes at least one offset caster 120.
[0035] With larger computing devices received by the mount 102, the
stability of the computing device support 100 may be affected. For
example, for a computing device (e.g., monitor) that is a weight
greater than 40 kg, a weight less than 50 kg, a diagonal length of
greater than 150 cm, or combinations thereof, the center of gravity
of the computing device support 100 with a mounted computing device
may move toward the back of the computing device support 100. In at
least one implementation, the use of an offset caster may adjust
the center of gravity of the computing device support 100 to offset
the effects of the computing device.
[0036] Referring back to FIG. 4-1, the casters 110, 120 are both
shown in an inward position. In this position, a distance 111-1
between the casters 110, 120 is shown. The center of gravity
without an offset caster 120 is shown as line 109. With the offset
caster 120, the center of gravity is shown as line 108-1 with the
casters 110, 120 in the inward position. Thus, the center of
gravity is altered by a distance 113-1 with the casters 110, 120 in
the inward position.
[0037] FIG. 4-2 is a side view of the implementation of the
computing device support 100 of FIG. 1 with the casters 110, 120 in
an outward position. In this position, a distance 111-2 between the
casters 110, 120 is shown. The center of gravity without an offset
caster 120 is shown as line 109. With the offset caster 120, the
center of gravity is shown as line 108-2 with the casters 110, 120
in the outward position. Thus, the center of gravity is altered by
a distance 113-2 with the casters 110, 120 in the outward
position.
[0038] FIG. 4-3 is a side view of the implementation of the
computing device support 100 of FIG. 1 with the front casters 120
in an inward position and the rear casters 110 in an outward
position. In this position, a distance 111-3 between the casters
110, 120 is shown. The center of gravity without an offset caster
120 is shown as line 109. With the offset caster 120, the center of
gravity is shown as line 108-3 with the front casters 120 in an
inward position and the rear casters 110 in an outward position.
Thus, the center of gravity is altered by a distance 113-3 with the
front casters 120 in an inward position and the rear casters 110 in
an outward position.
[0039] FIG. 5 is an isometric view of an implementation of an
offset caster 120 as shown in FIGS. 1 through 4-3. The offset
caster 120 includes a wheel 122 and an axle 124 connected to the
wheel 122. As shown, the axle 124 extends around the wheel 122. In
other implementations, the axle 124 may be otherwise
positioned.
[0040] The axle 124 is connected to an offset base 126. The offset
base 126 may include a connection 128. The connection 128 may
connect a computing device support (e.g., computing device support
100) to the offset caster 120. For example, the connection 128 may
connect to a leg 104 of a computing device support. The caster 120
may include a brake 130. The caster 120 may pivot about the brake
130.
[0041] FIG. 6-1 is a top view of the implementation of the offset
caster 120 of FIG. 1 with the wheel 122 in an inward position. In
other words, the wheel 122 may be oriented toward an inside of a
computing device support. FIG. 6-2 is a top view of the
implementation of the offset caster 120 of FIG. 1 with the wheel
122 in an outward position. In other words, the wheel 122 may be
oriented away from the inside of a computing device support. As
shown in FIG. 6-2, the axle 124 may wrap, at least partially,
around the wheel 122.
[0042] Referring generally to FIGS. 6-1 and 6-2, the leg 104 may
connect to the offset base 126 at an angle. As shown, the leg 104
connects to the offset base 126 at an angle (not labeled) from the
vertical relative to the side face of the offset base 126 and at an
angle (not labeled) from the vertical relative to the front face of
the offset base 126, as shown. In other implementations, the leg
104 may be parallel to the vertical or may vary from the vertical
in only one direction (e.g., only relative to the side face or the
front face).
[0043] A distance 123 from the front edge of the leg 104 and a
centerline of the axle 124 is shown. In the inward position, the
distance 123-1 is relatively small. In the outward position, as
shown in FIG. 6-2, the distance 123-2 is relatively large. In other
words, the distance 123-1 in the inward position may be smaller
than the distance 123-2 in the outward position.
[0044] A distance 125 may be defined from the center of the brake
130 to the front edge of the leg 104. The distance 125-1 in FIG.
6-1 and the distance 125-2 in FIG. 6-2 are the same, because the
caster 120 pivots about the brake 130. In implementations where the
caster 120 pivots about another point, the distance 125 may change
between the inward and outward positions (as well as sideways
positions).
[0045] A distance 127 may be defined from the center of the brake
130 to the front edge of the leg 104. The distance 127-1 in FIG.
6-1 and the distance 127-2 in FIG. 6-2 are the same, as the brake
130 does not change position in the top view from the inward to the
outward position.
[0046] FIGS. 7-1 through 7-3 are side views illustrating internal
components of the implementation of the offset caster 120 of FIG. 1
with the wheel 122 in an inward position. FIG. 7-1 illustrates the
brake 130 in a free position, FIG. 7-2 illustrates the brake 130 in
a caster locked position, and FIG. 7-3 illustrates the brake 130 in
the caster locked and a wheel locked position. FIG. 7-4 is a side
view of the implementation of the offset caster 120 of FIG. 1 with
the wheel 122 in an outward position and the brake 130 in the free
position.
[0047] FIG. 7-1 illustrates a distance 115 between the brake 130
and the leg 104. This distance 115 may facilitate a user's access
to the brake 130, regardless of the position of the wheel 122. In
other words, whether the wheel 122 is in the inward, outward,
sidewards, or otherwise positioned, the user may access the brake
130 without having to move the wheel 122.
[0048] A distance 116 from the center of the wheel 122 to the top
of the offset base 126 is also shown. The brake 130 may utilize
space in this distance 116 for various components as will be
described below.
[0049] The brake 130 may have a dimension 131. The dimension in
FIGS. 7-1 through 8 is the diameter of the brake 130. In other
implementations, the dimension 131 may be a width or other major
dimension.
[0050] Referring generally to FIGS. 7-1 through 7-4, the brake 130
includes an actuator 132 that is connected to a caster brake 134
and a wheel brake 136. The wheel brake 136 is shown as being
slidable within the caster brake 134. The offset base 126 includes
a caster brake receptacle 135 and a wheel brake receptacle 137.
[0051] The brake 130 may include a brake index 138. The brake index
138 is shown on the side of FIGS. 7-1 through 7-3 and may be found
around an inside of the offset base 126. The brake index 138 may
control the brake 130. As shown in FIGS. 7-1 through 7-3, the brake
index 138 may create three positions for the brake 130, the free
position, the caster locked position, and the wheel locked
position. In other implementations, more or fewer positions may be
used. In the caster locked position, rotation of the wheel 122
about an axis perpendicular to an axis of the axle 124 is limited.
In the wheel locked position, rotation of the wheel 122 about the
axle 124 is limited.
[0052] The brake 130 may be biased toward a position. As shown, the
brake 130 may be biased toward the free position. For example, a
biasing element (not shown), such as a spring, may bias the brake
130 toward the free position.
[0053] The brake 130 may include a brake pin 139. The brake pin 139
may be located on the brake 130. In other implementations, the
brake index 138 may be on the brake 130 while the brake pin 139 may
be on the offset base 126. As shown in FIGS. 7-1 through 7-3, the
brake index 138 may include a channel in which the brake pin 139
may slide. When the actuator 132 is first activated (e.g., pushed),
the brake pin 139 may move from a first position (e.g., the free
position) to a second position (e.g., the caster locked position).
The brake pin 139 may be retained in the second position until the
actuator 132 is actuated again. When the actuator 132 is second
activated, the brake pin 139 may move from the second position
(e.g., the caster locked position) to a third position (e.g., the
free position). The brake pin 139 may be retained in the third
position until the actuator 132 is actuated again. When the
actuator 132 is third actuated, the brake pin 139 may move from the
third position (e.g., the free position) to a fourth position
(e.g., the wheel locked position and caster locked position). The
brake pin 139 may be retained in the fourth position until the
actuator 132 is actuated again. When the actuator 132 is fourth
actuated, the brake pin 139 may move from the fourth position
(e.g., the wheel locked position and the caster locked position)
back to the first position (e.g., the free position).
[0054] As shown in FIGS. 7-1, 7-4 and 8, in the first position, the
caster brake 134 is not engaged with the offset base 126 and the
wheel brake 136 is not engaged with the wheel 122. As shown, a
distance 133-1 is formed between the top of the offset base 126 and
the top of the brake 130. The distance 133-1 is the largest, as
shown. In the free position, the offset caster 120 may rotate about
the brake 130 and the wheel 122 may rotate about the axle (e.g.,
axle 124). As shown in FIG. 7-2, in the second position, the caster
brake 134 is engaged with the caster brake receptacle 135 while the
wheel brake 136 is not engaged with the wheel 122. In this
position, the distance 133-2 is smaller than the distance 133-1 of
the free position. As shown in FIG. 7-3, in the fourth position,
the caster brake 134 is engaged with the caster brake receptacle
135 and the wheel brake 136 is engaged with the wheel 122. In this
position, the distance 133-3 is smaller than both the distance
133-2 of the caster locked position and the distance 133-1 of the
free position.
[0055] In order to engage both the wheel brake 136 and the caster
brake 134, the caster brake 134 may be formed of an elastomeric
material. For example, as shown in FIG. 7-3, the caster brake 134
may deform sufficiently to allow the wheel brake 136 to engage the
wheel 122. In other implementations, the caster brake 134 and the
wheel brake 136 may be separated and/or may be separately
actuated.
[0056] FIG. 8 is a front view of the implementation of the offset
caster 120 of FIG. 1 with the brake 130 in the free position. As
shown in FIG. 8, the axle 124 may have a gap 140 between the axle
124 and the ground. An axis 141 may extend through the wheel 122
and may be colinear with an axis of the axle 124. An axis 142 may
extend perpendicular to the axis 141. The axis 142 may extend
through the center of the brake 130. In other implementations, the
axis 142 may extend through another portion of the offset base 126.
The brake 130 may limit rotation about the axis 141 (e.g., about
the wheel 122) and/or may limit rotation of the offset caster 120
about the axis 142 (e.g., about the brake 130).
[0057] Referring briefly back to FIG. 5, the brake 130 may extend
above a top surface of the offset base 126. A portion of the brake
130 above the top surface may be colored to indicate the state of
the brake 130. For example, the portion may be green to indicate
that the device is unlocked. In another example, the portion may be
partially green at the bottom to indicate that the axle is free and
partially yellow at the top to indicate that the wheel is free, but
the axle is locked.
[0058] FIG. 9 is a front view of a second implementation of the
offset caster 220 and FIG. 10 is a side view of the implementation
of the offset caster 220 of FIG. 9. Referring generally to FIGS. 9
and 10, the offset caster 220 may include a wheel 222 supported by
an axle 224. The axle 224 of the offset caster 220 of FIGS. 9 and
10 may differ from the axle 124 of the implementation of an offset
caster 120 of FIGS. 1 through 8. For example, the axle 224 may
extend through the wheel 222. In another example, the axle 224 may
be forked.
[0059] The axle 224 may be connected to an offset base 226. As with
the offset base 126 of FIG. 1 through 8, the offset base 226 of
FIGS. 9 and 10 a leg 204 may connect to the offset base 226 at an
angle.
[0060] The axle 224 may connect to the offset base 226 by a
connection 228. The connection 228 may extend into the offset base
226 to provide support for the axle 224. The offset base 226 may
include a connection surface. As shown, the connection surface may
include bearings 229. The bearings 229 may facilitate rotation of
the offset caster 220 about the connection 228.
[0061] Unlike the offset caster 120 of FIGS. 1 through 8, the
offset caster 220 of FIGS. 9 and 10 may not include a brake (e.g.,
brake 130). In some implementations, the offset caster 120 of FIGS.
1 through 8 and/or the offset caster 220 of FIGS. 9 and 10 may
include or exclude a brake (e.g., brake 130).
[0062] The articles "a," "an," and "the" are intended to mean that
there are one or more of the elements in the preceding
descriptions. The terms "comprising," "including," and "having" are
intended to be inclusive and mean that there may be additional
elements other than the listed elements. Additionally, it should be
understood that references to "one implementation" or "an
implementation" of the present disclosure are not intended to be
interpreted as excluding the existence of additional
implementations that also incorporate the recited features. For
example, any element described in relation to an implementation
herein may be combinable with any element of any other
implementation described herein. Numbers, percentages, ratios, or
other values stated herein are intended to include that value, and
also other values that are "about" or "approximately" the stated
value, as would be appreciated by one of ordinary skill in the art
encompassed by implementations of the present disclosure. A stated
value should therefore be interpreted broadly enough to encompass
values that are at least close enough to the stated value to
perform a desired function or achieve a desired result. The stated
values include at least the variation to be expected in a suitable
manufacturing or production process, and may include values that
are within 5%, within 1%, within 0.1%, or within 0.01% of a stated
value.
[0063] A person having ordinary skill in the art should realize in
view of the present disclosure that equivalent constructions do not
depart from the spirit and scope of the present disclosure, and
that various changes, substitutions, and alterations may be made to
implementations disclosed herein without departing from the spirit
and scope of the present disclosure. Equivalent constructions,
including functional "means-plus-function" clauses are intended to
cover the structures described herein as performing the recited
function, including both structural equivalents that operate in the
same manner, and equivalent structures that provide the same
function. It is the express intention of the applicant not to
invoke means-plus-function or other functional claiming for any
claim except for those in which the words `means for` appear
together with an associated function. Each addition, deletion, and
modification to the implementations that falls within the meaning
and scope of the claims is to be embraced by the claims.
[0064] It should be understood that any directions or reference
frames in the preceding description are merely relative directions
or movements. For example, any references to "front" and "back" or
"top" and "bottom" or "left" and "right" are merely descriptive of
the relative position or movement of the related elements.
[0065] The present disclosure may be embodied in other specific
forms without departing from its spirit or characteristics. The
described implementations are to be considered as illustrative and
not restrictive. The scope of the disclosure is, therefore,
indicated by the appended claims rather than by the foregoing
description. Changes that come within the meaning and range of
equivalency of the claims are to be embraced within their
scope.
