DESCRIPTION
[0006] The present concepts relate to devices, such as computing
devices employing hinge assemblies that can rotationally secure
first and second device portions relative to a first hinge axis
that relates to the first portion and a second hinge axis that
relates to the second portion. From one perspective, some of the
present hinge assemblies can be viewed as being `self-regulating`
in that rotation is controlled so that an extent of rotation around
the first hinge axis corresponds to an extent of rotation around
the second hinge axis.
[0007] Introductory FIG. 1 shows an example device 100 that has
first and second portions 102 and 104 that are rotatably secured
together by a hinge assembly 105, which in this case is manifest as
a pair of a self-regulating hinge assemblies 106.
[0008] The first portion 102 can extend from a hinge end 108 to a
distal end 110. The second portion 104 also can extend from a hinge
end 112 to a distal end 114. The hinge assembly 105 can define two
hinge axes 116. The first portion 102 can rotate around first hinge
axis 116(1) and the second portion 104 can rotate around second
hinge axis 116(2). The first portion 102 can include opposing first
and second major surfaces 118 and 120 (hereinafter, first and
second surfaces). Similarly, the second portion 104 can include
opposing first and second major surfaces 122 and 124 (hereinafter,
first and second surfaces). (Note the second surfaces 120 and 124
are facing away from the viewer and as such are not directly
visible in this view, but are shown and designated in subsequent
FIGS.).
[0009] In some implementations, displays 126 can be positioned on
the first and/or second surfaces. In this case, displays 126(1) and
126(2) are interposed between the self-regulating hinge assemblies
106(1) and 106(2). In the illustrated configuration, the displays
126 are positioned on first surfaces 118 and 122, respectively and
curve or wrap around hinge ends 108 and 112 between self-regulating
hinge assemblies 106(1) and 106(2) onto second surfaces 120 and
124, respectively. Thus, from one perspective, the displays are
interposed in that the self-regulating hinge assemblies 106 are
positioned at the extremes of the first and second portions and the
displays extend between them on the first surfaces and wrap around
to the second surfaces between the self-regulating hinge assemblies
106.
[0010] FIGS. 2A-2D collectively show a use case scenario of device
100. FIG. 2A starts with device 100 in the closed orientation where
the first and second portions 102 and 104 are positioned against
one another and are rotatably secured by hinge assembly 105. In
this case, the second surfaces are facing outwardly with the first
portion's second surface 120 facing the reader and the first
surfaces (designated in FIG. 2B) facing inwardly. The closed
orientation can be very compact and easy for the user 202 to
transport. For instance, the device may fit in the user's pocket.
Further, the first surfaces can be protected in this closed
orientation by the second surfaces. The device can be biased to
maintain this orientation until acted upon by the user. At this
point user 202 is starting to open the device 100 (e.g., rotate the
device portions 102 and 104 away from one another).
[0011] FIG. 2B shows the device 100 opened to an angle .alpha.
defined between the first and second portions 102 and 104 of about
110 degrees. This orientation can be thought of as a `notebook` or
`laptop` orientation. The notebook orientation can be manifest as
an angle in a range from about 90 degrees to about 150 degrees. In
this case, the device portions 102 and 104 are configured to
maintain this relative orientation while the user 202 uses the
device. In this example, video content is presented on a GUI 204(1)
on display 126(1) of the first portion 102 and a virtual keyboard
is presented on display 126(2) on second portion 104. The user can
control GUI 204(1) via the virtual keyboard of GUI 204(2).
[0012] FIG. 2C shows the device 100 rotated until the relative
angle .alpha. is about 180 degrees between the first and second
portions 102 and 104. In this orientation, a single GUI 204(3) can
be presented collectively across displays 126(1) and 126(2). This
GUI 204(3) offers basically twice the display area of either device
portion 102 or 104. The device can be biased to maintain this fully
open orientation for viewing, yet when not utilized by the user
202, the user can close the device 100 to a compact easy to carry
configuration (e.g., see FIG. 2A) that protects the displays 126
from damage.
[0013] FIG. 2D shows another orientation where the angle .alpha. is
about 270 degrees (or in a range from about 240 degrees to about
330 degrees). This orientation can be thought of as an `alarm
clock` orientation where the device stands on its own and the
displays 126 are readily visible to the user.
[0014] Note that while obscured by the displays 126, several
electronic components, such as circuit boards, processors, and/or
storage/memory can be secured to the first and second portions 102
and/or 104.
[0015] The processor can generate GUIs 204 for presentation on the
displays 126. In some implementations, the processor may generate
different GUIs for the displays when the first and second portions
102 and 104 are in some orientations and a single GUI for a
combined presentation in other orientations. For instance, when the
first and second portions are oriented at 90 degrees relative to
one another, the processor may generate a first GUI for
presentation on the first portion and a second GUI for presentation
on the second portion. When the first and second portions are
oriented to 180 degrees, the processor can generate a single GUI
that is collectively presented across both displays to create a
larger display area. In other orientations, such as the alarm clock
orientation, the same GUI may be presented on both the first and
second portions. For instance, the time could be presented on both
portions so that it is visible from more positions around the
device.
[0016] Stated another way, in some configurations, the first
surfaces 118 and 122 can be manifest as displays 126, such that in
the fully open orientation of FIG. 2C the displays can work
cooperatively to create a larger (e.g., 2x) display area. In some
cases, the second surfaces 120 and 124 can be manifest as
protective covers so that in the orientation of FIG. 2A the
protective covers protect the displays of the first surfaces. In
other configurations, both the first and second surfaces can
include displays, or neither can include displays.
[0017] FIGS. 3A-3C collectively show more details of example
self-regulating hinge assembly 106(1). The self-regulating hinge
assembly 106(1) can include a communication member 302 (not shown
in FIG. 3A) and first and second hinge bodies 304(1) and 304(2).
The hinge bodies can define primary gears 306 that can interact
with intervening or secondary gears 308. The hinge bodies can also
have a curved shape (e.g., radius of curvature r.sub.1) around the
axes 116 that can facilitate rotation of the hinges. This aspect
will be discussed in more detail below relative to FIGS.
10A-10E.
[0018] The communication member 302 can include hinge pins 310 that
pass through the primary gears 306 and apertures 312 in the first
and second bodies 304. In some implementations, the apertures 312
can be sized so the that the bodies 304 act as friction cylinders
for the hinge pins 310 (e.g., provide a degree of frictional
resistance that can hold the portions in an existing orientation
unless acted upon by the user). Retainers 314 can secure the hinge
pins 310 with the first and second bodies 304. The communication
member 302 can also be configured to secure the secondary gears 308
in engagement with the primary gears 306. In this example, the
secondary gears 308 include protuberances or pins 316 that are
received by bores 318 in the communication member 302 to retain the
secondary gears in engaging relation with each other and the
primary gears.
[0019] The communication member 302 can also define a passage 320
configured to receive a conductor, such as a flexible printed
circuit (FPC) 322. The conductor can connect displays and/or other
electronic components on the first portion with displays and/or
other electronic components on the second portion. A retainer 324
can maintain the FPC in the communication member 302. Similarly, a
retainer 326 can retain secondary gears 308 in the communication
member 302.
[0020] FIGS. 4A-8B collectively show operation of the
self-regulating hinge assembly 106(1) of device 100. FIGS. 4A and
4B show the first and second portions 102 and 104 at zero degrees
relative to one another. FIGS. 5A and 5B show the first and second
portions at 90 degrees of relative rotation. FIGS. 6A and 6B show
the first and second portions at 180 degrees of relative rotation.
FIGS. 7A and 7B show the first and second portions at 300 degrees
of relative rotation. FIGS. 8A and 8B show the first and second
portions at 360 degrees of relative rotation.
[0021] FIGS. 4A-4B show the device 100 in the closed positioned
with the first and second portions 102 and 104 against one another
such that first surfaces 118 and 122 are parallel to and opposing
one another. The first and second surfaces 118 and 122 are also
parallel to a reference line 402. The relevance of reference line
402 will be explained below relative to FIGS. 5A-8B.
[0022] FIGS. 5A and 5B show the device 100 opened until the first
and second portion are oriented about 90 degrees from one another
(as measured relative to first surfaces 118 and 122). Note also,
that gear interaction ensures that rotation around one hinge axis
116 causes a corresponding amount of rotation in the other hinge
axis 116. In this example, the corresponding rotation is
one-to-one, such that 45 degrees of rotation around hinge axis
116(1) accompanies 45 degrees of rotation around hinge axis 116(2).
In the illustrated configuration, primary gear 306(1) is positioned
around hinge axis 116(1) and interacts in a timed manner with
secondary gear 308(1). The secondary gear 308(1) interacts in a
timed manner with secondary gear 308(2). The secondary gear 308(2)
interacts in a timed manner with primary gear 306(2), which is
positioned around hinge axis 116(2). As such, a degree of rotation
of first portion 102 around hinge axis 116(1) produces a
corresponding rotation of second portion 104 around hinge axis
116(2). Thus, from one perspective the self-regulating hinge
assemblies can control the extent and/or timing of rotation around
the two hinge axes 116.
[0023] FIGS. 6A and 6B show the device 100 with the device portions
rotated to 180 degrees. In this implementation the self-regulating
hinge assembly 106(1) causes the 180 degrees of rotation to be
achieved by 90 degrees of rotation by first portion 102 around
hinge axis 116(1) and an equal rotation by second portion 104
around hinge axis 116(2) relative to line 402.
[0024] FIGS. 7A and 7B show further rotation of the device so that
the device portions 102 and 104 are 300 degrees apart. Consistent
with the discussion above, equal rotation occurs around each hinge
axis 116 due to the self-regulating hinge assembly 106(1). Thus,
first portion 102 has rotated 150 degrees around hinge axis 116(1)
relative to line 402 and second portion 104 has rotated 150 degrees
around hinge axis 116(2).
[0025] FIGS. 8A and 8B show complete rotation of this
implementation to 360 degrees with the first and second surfaces
102 and 104 parallel to and facing away from one another. Note that
other implementations can have other ranges of rotation besides 360
degrees. For instance, another implementation can have a range of
rotation of 130 degrees while still another implementation has a
range of rotation of 180 degrees, for example. Regardless, the
self-regulating hinge assembly 106(1) can ensure corresponding
rotation around the first and second hinge axes 116(1) and 116(2).
Thus, when a user rotates the first and second portions toward
and/or away from one another, the self-regulating hinge assembly
can ensure that rotation around the first hinge axis corresponds to
rotation around the second hinge axis. For instance, in this
implementation the rotation can be performed equally around the
first and second hinge axes 116(1) and 116(2). As such, if the user
rotates the first and second portions back from the 360 degree
orientation of FIGS. 8A and 8B, the self-regulating hinge assembly
106(1) can ensure equal and synchronized and simultaneous rotation
around both hinge axes.
[0026] FIGS. 9A and 9B show another example self-regulating hinge
assembly 106A(1) on device 100A. In this case, primary gears 306A
are associated with their respective bodies 304A and rotate around
hinge axes 116. In this example, the primary gears 306A(1) and
306A(2) directly engage one another to regulate rotation of first
portion 102 around hinge axis 116(1) and second portion 104 around
hinge axis 116(2).
[0027] FIGS. 10A-10E and 11 collectively show additional features
of example device 100. In this implementation, displays 126(1) and
126(2) are positioned on first surfaces 118 and 122, respectively.
Further, the displays wrap around the hinge ends 108 and 112 of the
first and second portions 102 and 104 onto the second surfaces 120
and 124, respectively. In this case, the displays 126 wrap at the
hinge ends along a curve (e.g. radius of curvature) that has the
same profile as a profile of the self-regulating hinge assembly 106
when viewed along the axes of rotation. These profiles both have a
radius r.sub.1 relative to the hinge axes 116. Recall from the
discussion of FIGS. 3A-3C above that the self-regulating hinge
assembly 106(1), as defined by first and second bodies 304, can
have this same curved or radiused profile represented by radius
r.sub.1. This shared radius can allow the first and second portions
to be rotated relative to one another while maintaining a
consistent and small gap G (designated on FIG. 11) between the
first and second portions 102 and 104 at the self-regulating hinge
assemblies 106 and between the displays 126(1) and 126(2) during
the range of orientations.
[0028] In this implementation, the displays 126 are visible on the
first surfaces 118 and 122. The displays then wraps around the
hinge ends 108 and 112 to the second surfaces 120 and 124. In the
illustrated implementation, on the second surfaces 120 and 124 a
region 1002 of the display 126 are visible and a remainder or
remaining region 1004 of the display is obscured. In other
implementations, the displays can be visible across the second
surfaces in a similar manner to the first surfaces. Having the
displays visible as the displays curve around the hinge ends and on
the second surfaces can allow content to be displayed and be
visible to the user even when the first and second portions 102 and
104 are in the closed or in the zero degree orientation of FIG.
10A.
[0029] Further, in this implementation, as can be appreciated in
FIG. 11, the displays 126 can include connectors 1102 on the
remainder 1004 of the displays. The connectors can connect the
displays to each other and/or to other components via conductors,
such as flexible printed circuits that are connected to the
connectors. This configuration can allow the displays to extend
across more of the first surfaces and the hinge ends than would
otherwise be possible (e.g., increased screen real estate) if the
connectors occupied area of the first surface.
[0030] The illustrated implementation includes another radiused
curve or radius of curvature (r.sub.2) that is less than r.sub.1
and extends between the first and second surfaces (118 and 120 and
122 and 124). This second radiused curve can provide a location for
the connectors 1102 to be connected to the conductors without
occupying real estate on the device that could otherwise be
utilized for the displays to present content to the user.
[0031] Individual elements of the hinge assembly 106 can be made
from various materials, such as metals, plastics, and/or
composites. These materials can be prepared in various ways, such
as in the form of sheet metals, die cast metals, machined metals,
3D printed materials, molded or 3D printed plastics, and/or molded
or 3D printed composites, among others, or any combination of these
materials and/or preparations can be employed.
[0032] The present hinge assembly concepts can be utilized with any
type of device, such as but not limited to notebook computers,
smart phones, wearable smart devices, tablets, and/or other types
of existing, developing, and/or yet to be developed devices.
[0033] Various methods of manufacture, assembly, and/or use for
hinge assemblies and devices are contemplated beyond those shown
above relative to FIGS. 1-11.
[0034] Various device examples are described above. Additional
examples are described below. One example includes a device
comprising a first portion and a second portion. The device further
comprises a pair of self-regulating hinge assemblies rotatably
securing hinge ends of the first and second portions around a first
hinge axis associated with the first portion and a second hinge
axis associated with the second portion so that an extent of
rotation around the first hinge axis corresponds to an extent of
rotation around the second hinge axis. The device further comprises
a first display positioned on the first portion and wrapped around
the hinge end between the pair of hinge assemblies, and also
comprises a second display positioned on the second portion and
wrapped around the hinge end between the pair of hinge
assemblies.
[0035] Another example can include any of the above and/or below
examples where the first display is wrapped axially around the
first hinge axis and the second display is wrapped axially around
the second hinge axis.
[0036] Another example can include any of the above and/or below
examples where the first display is wrapped axially around the
first hinge axis at a first radius of curvature and the second
display is wrapped 180 axially around the second hinge axis at the

[0037] Another example can include any of the above and/or below
examples where beyond wrapping around the hinge end, the first
display extends generally orthogonally away from the first hinge
axis and then wraps back toward the first hinge axis at a second
radius of curvature that is smaller than the first radius of
curvature.
[0038] Another example can include any of the above and/or below
examples where the pair of self-regulating hinge assemblies each
comprise first and second friction cylinders through which
individual hinge axes pass and where a curved profile of the

and second displays.
[0039] Another example can include any of the above and/or below

body that is secured to the first portion and the second friction
cylinder is defined by a second body that is secured to the second
portion.

include first and second hinge pins that reside within respective
first and second friction cylinders.

that provide timing of the self-regulating hinge assemblies.

[0044] Another example can include any of the above and/or below
examples where the first and second hinge pins extend from a
communication member.
[0045] Another example can include any of the above and/or below
examples where the gears are rotatably retained in the
communication member.
[0046] Another example can include any of the above and/or below
examples where the communication member defines a passage between
the first portion and the second portion and further comprising a
flexible printed circuit positioned in the passage and electrically
connecting components of the first portion to components of the
second portion.
[0047] Another example can include any of the above and/or below
examples where the components of the first portion comprise the
first display and where the components of the second portion
comprise the second display.
[0048] Another example can include a device comprising a first
portion that includes a first display that is wrapped around a
hinge end of the first portion and a second portion that includes a
second display that is wrapped around a hinge end of the second
portion. The device further comprises a pair of hinge assemblies
rotatably securing the hinge ends of the first and second portions
so that a gap between the hinge end of the first display and the
hinge end of the second display remains constant during rotation of
the first and second portions.
[0049] Another example can include any of the above and/or below
examples where the pair of self-regulating hinge assemblies are
timed so that the rotation occurs equally relative to the first and
second portions.
[0050] Another example can include any of the above and/or below
examples where the pair of self-regulating hinge assemblies are
timed by gears.
[0051] Another example can include any of the above and/or below
examples where the rotation occurs around either the first portion
or the second portion.
[0052] Another example can include a device comprising a first
portion that includes a first display that is wrapped in a radiused
profile around a hinge end of the first portion and a second
portion that includes a second display that is wrapped in a
radiused profile around a hinge end of the second portion. The
device further comprises a pair of hinge assemblies rotatably
securing the hinge ends of the first and second portions with the
first and second displays interposed therebetween and where the
pair of hinge assemblies have radiused profiles that match the
radiused profiles of the first and second displays.
