Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to a wristband, and
in particular, to a wristband for a watch, wherein the watchband
can flex and pivot about both longitudinal and transverse axes.
[0003] 2. Description of the Related Art
[0004] Many types of straps and bracelets, and in particular,
watchbands designed to hold a timepiece around a user's wrist, are
known in the art. However, it is difficult to design a watchband
that both resists wear and comfortably conforms to a user's
wrist.
[0005] A number of watchbands have been developed in attempts to
provide a watchband that is either wear resistant or that conforms
comfortably to a user's wrist. For example, watchbands have been
developed that comprise a flexible material, such as a plastic or
leather strap. These watchbands may have improved conformance to a
user's wrist, but are subject to wear and may require regular
replacement, which can be costly and inconvenient to the owner of
the watch. Watchbands have been developed for improved
wear-resistance, such as those comprising stronger or rigid
materials, such as metal. However, these rigid designs may require
complex mechanisms such as hinges and springs in order for the
watchband to fit around a user's wrist. These mechanisms may also
be prone to failure, and are thus also expensive to maintain,
repair and replace. Further, metal watchband designs have limited
flexibility, and thus may not conform to a user's wrist, and are
uncomfortable to wear.
SUMMARY OF THE INVENTION
[0006] Embodiments of the wristwatch band of the present invention
have several features, no single one of which is solely responsible
for their desirable attributes. Without limiting the scope of this
invention, its more prominent features will now be discussed
briefly. However, not all of the following features are necessary
to achieve the advantages of the wristwatch band. Therefore, none
of the following features should be viewed as limiting. After
considering this discussion, and particularly after reading the
section entitled "Detailed Description of the Preferred
Embodiments," one will understand how the features of the preferred
embodiments provide advantages over prior art.
[0007] There is provided in accordance with one aspect of the
present invention, a band having longitudinal, transverse and
torsional flexibility. The band may be worn on a wrist or ankle of
a wearer, and may support a watch or other device. The band
comprises a plurality of segments extending in a loop for
encircling the wrist. A first segment extends at least partially
across a width of the band, and comprises a first section and a
second section. The first and second sections are separated by a
longitudinal flexible joint.
[0008] A second segment is connected to the first segment, the
first and second segments aligned along a longitudinal axis of the
band. The second segment is flexible about a transverse axis
relative to the first segment.
[0009] The second segment may comprise first and second
side-by-side sections. The sections are separated by a
longitudinally extending flexible joint. The band comprises a
plurality of segments flexibly connected end to end along the
length of the band. This results in a plurality of transverse flex
lines, allowing the band to be flexed into a circular configuration
such as for wearing on a wrist. The band may also be flexed about
at least one longitudinal flex line, extending circumferentially
around the wrist.
[0010] There is provided in accordance with another aspect of the
present invention, a method of enabling a band to conform to
noncylindrical anatomy, such as a wrist at the junction with the
hand.
[0011] The band comprises at least one longitudinally extending
flex line, which, in the as worn orientation, encircles the wrist.
The band additionally comprises a plurality of transverse flex
lines, which, in the as worn orientation, extend in parallel to the
longitudinal axis of the wearer's wrist.
[0012] As the band slides in a distal direction with respect to the
wearer's arm, a distal row of modular sections in the band can
flare radially outwardly in the distal direction, with respect to a
proximal row of modular segments, spaced apart around the
circumference of the wearer's wrist.
[0013] Further features of the present invention will become
apparent from the detailed descriptions of preferred embodiments
which follows, when considered together with the attached drawings
and claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0029] FIG. 1 illustrates a partial side cross-sectional
perspective view of a conventional wristband that can be worn
around a user's wrist. The wristband can be a watchband 10,
configured to hold a timepiece (not shown). Many aspects of the
watchband 10 shown in FIG. 1 can be used in various embodiments of
the present invention. The watchband 10 can comprise a plurality of
segments 20, wherein each segment thereof extends across a width W
of the watchband 10. The plurality of segments 20 can comprise a
segment 21 that is pivotably, or hingeably, connected along its
width to an approximately adjacent segment 22. Segments 21 and 22
can be pivotably connected to each other with a rotatable element
30. Rotatable element 30 allows segment 21 to pivot relative to
segment 22 about a transverse axis 40 configured between segments
21 and 22 and extending through the width of watchband 10. In the
illustrated embodiment, transverse axis 40 can extend through the
center of rotation of the rotatable element 30. Rotatable element
30 can comprise any type of element that hingeably connects segment
21 to segment 22, such as a plurality of alternating apertured tabs
or knuckles, pivotably held together by a hinge pin as is known in
the art. Here, for exemplary purposes, element 30 is illustrated as
a generic hinge 30. Segments 20 and hinges 30 can comprise many
different materials, although in conventional watchband designs,
segments 20 and hinges 30 typically comprise a rigid material, such
as a metal.
[0030] The hinge 30 can be configured between each segment in the
watchband 10, allowing each segment to pivot relative to an
approximately adjacent segment and function similarly to that
described above for segments 21 and 22. When the plurality of
segments 20 pivot, watchband 10 can at least partially wrap around
a central axis 50, forming a channel 60 through which a user can
extend his or her wrist. As used herein, a watchband is in a
"transversely wrapped" position when it at least partially wraps
around a central axis to form a channel through which a user can
extend his or her wrist.
[0031] Channel 60 can comprise many different geometries, such as
an oblong or approximately oval shape. In the illustrated
embodiment, channel 60 can be approximately cylindrical, comprising
a first opening 70a of a diameter .phi..sub.1 configured at its
proximal end, and a second opening 70b of a diameter .phi..sub.2
configured at its distal end. In a conventional watchband 10,
diameter .phi..sub.1 is approximately equal to diameter .phi..sub.2
because segments 20 and hinges 30 extend substantially across the
width of watchband 10 and the rigidity of the materials used for
segments 20 and hinges 30 do not allow the watchband 10 to flex or
pivot in a direction other than around transverse axis 40. As such,
the cross sectional area, shape, and orientation of opening 70a is
approximately equal to the cross sectional area, shape, and
orientation of opening 70b in a conventional watchband 10 with
segments 20 comprising a rigid material. Thus, the adjacent
segments 20 in a conventional watchband can only pivot about a
single, transverse axis 40 and can only provide a channel 60 of a
single, or continuous diameter, cross sectional area, shape, and
orientation throughout its axial length, through which a user can
extend his or her wrist.
[0032] FIGS. 2 and 3 are a schematic top and cross-sectional side
view, respectively, of a watch 100, which can include a watchband
110 connected to a timepiece 115. The watchband 110 illustrated in
FIGS. 2 and 3 is shown in a substantially unwrapped, or
substantially flat, position. As used herein, a watchband is in an
"unwrapped" or "flat" position when it does not pivot about a
longitudinal or transverse axis. Watchband 110 can comprise a
single integrated piece, or, as shown in the illustrated
embodiment, watchband 110 can comprise a first portion 110a and a
second portion 110b, connected to opposing sides of timepiece 115,
as is well known in the art. As used herein, the ends of first
portion 110a and second portion 110b that can be connected to
timepiece 115 are referred to as the "proximal" ends of portions
110a, 110b, and the ends of first portion 110a and second portion
110b that extend away from timepiece 115 and the proximal ends, are
referred to as the "distal" ends of watchband portions 110a,
110b.
[0033] First portion 110a can comprise a first connector 112a
connected to the distal end of first portion 110a. Second portion
110b can comprise a second connector 112b connected to the distal
end of second portion 110b. First connector 112a and second
connector 112b can be configured to connect and disconnect the
distal ends of first portion 110a and second portion 110b, as is
known in the art. For example, first connector 112a can be sized
and shaped to receive second connector 112b, or 112b can be sized
and shaped to receive first connector 112a, such as with a buckle
and corresponding strap, or a pair of interlocking clips or clasps,
or other watchband connectors known in the art. First connector
112a and/or second connector 112b can comprise a mechanism that is
moveable between a locked and unlocked position, such as a latch,
to hold connectors 112a and 112b in a connected and disconnected
position, respectively.
[0034] Watchband 110 can comprise a plurality of segments 120 that
can be spaced along the length of sections 110a and/or 110b,
wherein each segment can extend at least partially across the width
of watchband 110. Segments 120 can comprise many different shapes,
such as square, rectangular or trapezoidal, and can vary in size
and shape along the length of watchband 110. Segments 120 can be
solid or hollow, and can be flat or have a surface profile or
surface structures to give watchband 110 an "armored" appearance.
In an embodiment, segments 120 can be an approximately rectangular
prism and can be approximately equal size. In a preferred
embodiment described further below, segments 120 can vary such as
progressively in size and shape along the length of watchband 110
and can comprise a lip, or sidewall extending away from an angled
top portion.
[0035] The plurality of segments 120 can comprise a first segment
121 that is pivotably connected along its width to a segment 122
configured approximately adjacent to segment 122 relative to the
length of watchband 110. Segments 121 and 122 can be pivotably
connected to each other to allow segment 121 to pivot relative to
segment 122 about a transverse axis 140 that extends through the
width of first section 110a. The plurality of segments 120,
segments 121 and 122, and transverse axis 140 can function
similarly to the manner described above and shown in FIG. 1 for the
plurality of segments 20, segments 21 and 22, and transverse axis
40, respectively. Segments 121 and 122 can be pivotably connected
to each other with a rotatable element 30 as described above (not
shown in FIGS. 2 and 3). In some embodiments, segments 121 and 122
can be pivotably connected to each other with a flexible element
130, as described further below. Note that the function and
structures described herein for the segments of any watchband
embodiment, such as adjacent segments 121 and 122 of watchband 110,
either individually, or in relation to each other as a pair of
adjacent segments, are for exemplary purposes, and can be employed
for any individual segments or pair of adjacent segments within the
plurality of segments for that watchband embodiment.
[0036] Segments 120 can comprise any of a variety of different
materials, such as a plastic or metal. Segments 120 can vary in
material along the length of watchband 110, and each individual
segment can comprise more than one material, such as a plated
metal. In some embodiments, segment 120 is a precious metal, such
as gold or silver. Segments 120 may alternatively comprise
stainless steel, titanium, magnesium, alloys such as
Nickel-Titanium alloys (Nitinol), carbon fiber composites and other
materials known in the art.
[0037] Each segment in the plurality of segments 120 can comprise
two or more side-by-side sections, with each section extending
partially across the width of watchband 110. The adjacent sections
can be configured on opposing sides of a longitudinal axis 80 which
extends along the length of watchband 110.
[0038] In the illustrated embodiment, segment 121 can comprise a
first section 121a configured approximately adjacent to a second
section 121b, extending across the width of watchband 110. The next
segment 122 can comprise a first section 122a configured
approximately adjacent to a second section 122b extending across
the width of watchband 110.
[0039] Sections 121a and 122a can be configured on one side of
longitudinal axis 80, with sections 121b and 122b configured on the
opposite side of longitudinal axis 80. Although longitudinal axis
80 is shown extending approximately centrally through the length of
watchband 110, in some embodiments, longitudinal axis 80 can be
laterally offset from the longitudinal midline. In other
embodiments, such as that shown in FIG. 9 and described further
below, two or more longitudinal axes 80 can extend through the
length of watchband 110, and segments 121 and 122 can comprise more
than two sections of the same or different size spaced across the
width of watchband 110. Although sections 121a and 122a are shown
as being approximately the same size as sections 121b and 122b,
respectively, in some embodiments, section 121a can be a different
size than section 121b, and section 122a can be a different size
than section 122b. Note that the function and structures described
herein for the sections of any segment within a watchband
embodiment, such as adjacent sections 121a, 121b of segments 121 of
watchband 110, either individually, or in relation to each other as
a pair of adjacent sections, are for exemplary purposes, and can be
employed for any individual sections or pair of adjacent sections
within the plurality of segments for that watchband embodiment.
[0040] Sections 121a and 122a can be pivotably or hingeably
connected to segments 121b and 122b, respectively, and can rotate
relative to each other about longitudinal axis 80, as will be
described further below. Sections 121a and 122a can be connected to
sections 121b and 122b, respectively, with a rotatable element 30
as described above in FIG. 1. In some embodiments, the adjacent
sections of the segments within watchband 110 are connected to a
flexible element so that the adjacent sections can rotate about the
longitudinal axis 80, as described presently.
[0041] Referring to FIGS. 2 and 3, watchband 110 can comprise a
flexible support element 130 connected to the plurality of segments
120. The flexible element 130 can comprise many different shapes
and sizes. In some embodiments, the flexible element 130 can
comprise a rod, or bar, or a plurality of rods or bars, extending
across the width and/or length of watchband 110. In some
embodiments, flexible element 130 can be an approximately
rectangular strip of flexible material that provides a structure on
which segments 120 can be mounted.
[0042] Flexible element 130 can be configured to connect portions
110a, 110b of watchband 110 to the timepiece 115. Flexible element
130 can be connected to timepiece 115 in many different ways, such
as with a snap or friction fit, clamps, clips, pin and loop or
other hinge, adhesive, or any other mechanical, chemical, thermal,
or other bonding methods known in the art. In some embodiments,
flexible element 130 can be hingeably connected to timepiece 115,
so that watchband portions 110a, 110b can rotate relative to
timepiece 115, as is known in the art. In a preferred embodiment,
flexible element 130 comprises an outer flange 151 that can extend
at an angle from the proximal end of flexible element 130. One or
more holes 150 can extend through flange 151, and corresponding
aligned holes can be configured on each side of timepiece 115.
Screws or other fasteners 152 can extend through holes 150 and
screw into corresponding holes on the side of timepiece 115 to
connect flexible element 130 and either of watchband portions 110a,
110b to timepiece 115.
[0043] The flexible element 130 can comprise any of a variety of
materials suitably flexible about a transverse axis and a
longitudinal axis as described herein. Flexible element 130 can
comprise elastomers or other plastics, rubber, or leather, or
composite materials such as reinforced fabrics, fibers or rebar.
Flexible element 130 can comprise layers or composite materials,
such as a rubber bonded with a flexible metal backing or fiber
reinforced polymers. In a preferred embodiment, flexible element
130 comprises rubber.
[0044] FIG. 4 is an enlarged partial cross-sectional elevational
side view of an embodiment of the watchband 110 illustrated in
FIGS. 2 and 3 in a transversely wrapped position. In this
embodiment, segments 120 can be mounted on a top surface 131 of
flexible support 130. Segments 120 can be mounted on flexible
support 130 in many different ways, such as with a mechanical
fastener, an interference and/or press fit, adhesive, and/or any
other mechanical, chemical, thermal, or other bonding methods known
in the art. In a preferred embodiment, segments 120 can be mounted
to flexible element 130 with screws, as described further below and
shown in FIGS. 7B-D and 7G-H. Flexible element 130 can comprise a
groove 132 that can extend at least partially across the width of a
bottom surface 133 of flexible element 130. The cross section of
groove 132 can comprise many different shapes, such as a rectangle,
triangle, trapezoid or semicircle. In a preferred embodiment,
groove 132 can extend across the entire width of flexible element
130 and can comprise an approximately rectangular cross-sectional
shape. Groove 132 can provide an airspace for breathability, or
provide a gripping function, when the flexible element 130 is worn
against a user's skin, and it can provide increased flexibility of
flexible element 130 along each transverse flex plane. The size and
shape of groove 132 can be varied to tune the amount of flexibility
of flexible support 130.
[0045] A transverse axis 140 can extend across the width of
flexible element 130 and below a gap 134 configured between
adjacent segments 121 and 122. Segments 121 and 122, transverse
axis 140, and flexible element 130 can function similarly to
segments 21 and 22, transverse axis 40, and hinge 30, respectively,
described above and shown in FIG. 1. A transverse axis 140 can be
configured for each corresponding pair of adjacent segments in the
plurality of segments 120, and is shown in FIG. 4 as being
configured only below segments 121 and 122 for simplicity.
[0046] In operation, a force can be applied to the ends of flexible
element 130 or watchband 110, in the directions shown by arrows 135
and 136. Flexible element 130 can flex in response to the applied
force, and segments 121 and 122 can pivot about the transverse axis
140 in response. When segments 121 and 122 pivot about the
transverse axis 140, the gap 134 increases or decreases in length.
For example, when segments 121 and 122 are moved in the direction
shown by arrow 136, the gap 134 can increase in length, and when
segments 121 and 122 are moved in the direction shown by arrow 135,
the gap 134 can decrease in length. As such, when segments 121 and
122 are moved in the direction shown by arrow 136, they pivot away
from each other, and when segments 121 and 122 are moved in the
direction shown by arrow 136, they pivot away from each other.
[0047] When the force is applied to flexible element 130, the
plurality of segments 120 can collectively pivot, as described
above for segments 121 and 122, moving watchband 110 about the
central axis 50 in the direction of the applied force. In this way,
watchband 110 can move from a transversely wrapped position to a
flat position, and vice versa. As described above, FIGS. 2 and 3
show watchband 110 in a flat position, and FIG. 4 shows watchband
110 in a transversely wrapped position. In an embodiment shown in
FIG. 4, watchband 110 can be moved from a flat position to a
transversely wrapped position by moving flexible element 130 about
the central axis 50 in the direction shown by arrows 136. Watchband
110 can be moved from a transversely wrapped position to a flat
position by moving flexible element 130 about the central axis 50
in the direction shown by arrows 135. When watchband 110 is in a
transversely wrapped position, it can form a channel or aperture
160 through which a user can extend his or her wrist. As such,
watchband 110 and channel 160 can function similarly to watchband
10 and channel 60, as described above and shown in FIG. 1. In an
embodiment shown in FIG. 4, when watchband 110 is in a transversely
wrapped position, the bottom surface 133 of flexible element 130
can face and contact the user's wrist, and segments 120 can face
outwardly from watchband 110 and the user's wrist. When segments
120 face outwardly from watchband 110, they can protect flexible
element 130 from wear, increasing the expected life of flexible
element 130.
[0048] FIG. 4A shows a schematic perspective side view of an
embodiment of the watchband shown in FIG. 4. In this embodiment,
the configuration of flexible element 130 and segments 120 on
watchband 110 are reversed relative to a user's wrist and timepiece
115 (not shown). In this embodiment, watchband 110 can be moved
from a flat position to a transversely wrapped position by moving
flexible element 130 about a central axis 50a in the direction
shown by arrows 135. In this embodiment, watchband 110 can be moved
from a transversely wrapped position to a flat position by moving
flexible element 130 about the central axis 50a in the direction
shown by arrows 136. When watchband 110 is in a transversely
wrapped position, it can form a channel 160a through which a user
can extend his or her wrist. In this embodiment, the top surfaces
of segments 120 face and contact the user's wrist. In this
embodiment, the bottom surface 133 of the flexible element 130
faces outwardly from watchband 110 and the user's wrist. In some
embodiments, a watchband 110 can be removably or pivotably
connected with timepiece 115 so the user can select between a
watchband in which flexible element 130 faces the user's wrist, as
shown in FIG. 4, and a watchband in which the segments 120 face the
user's wrist, as shown in FIG. 4A. In this way, watchband 110
and/or watchband 210 can be reversible. Note that in some
embodiments, a second plurality of segments can be connected to
flexible element 130 on a side opposite to the plurality of
segments 120, such as that described below and shown in FIG. 9.
[0049] FIG. 5A is a schematic cross-sectional end view of an
embodiment of the watchband 110 illustrated in FIGS. 2 and 3 viewed
from the longitudinal axis 80. FIG. 5A shows watchband 110 in a
flat position about longitudinal axis 80. FIG. 5A illustrates an
embodiment of segment 121 wherein sections 121a and 121b can
comprise a sidewall 124a connected to and extending at an angle
from a top section 124b. In an embodiment, sidewall 124a can extend
approximately perpendicular to top section 124b. The outer surface
of sidewall 124a can extend at an angle from top section 124b
within the range of from about 15.degree. to about 90.degree.,
often from about 35.degree. to about 55.degree.. See FIGS.
7A-7F.
[0050] Top section 124b and sidewall 124a can be solid or hollow,
and can be many different shapes, such as a triangular,
trapezoidal, or rectangular prism. In an embodiment shown in FIGS.
7A-7F, the top surface of a section 121a increases in thickness
towards the central longitudinal axis 80 and the complementary
section 121b also increases in thickness towards the longitudinal
axis 80 to form a ridge with a longitudinal gap between the two
adjacent sections that extends the length of watchband 110.
Referring again to FIG. 5A, top section 124b can be positioned on
the top surface 131 of flexible element 130, with sidewall 124a
extending over and engaging with at least a portion of a sidewall
130a of flexible element 130. In this way, segment 121 can wrap
around an edge of flexible element 130. Sidewall 124a can comprise
an inner surface 126a that engages with sidewall 130a and a surface
126b configured on the outer surface of 124a. Inner surface 126a
and outer surface 126b can be configured parallel to each other or
at an angle relative to each other. Section 121b can comprise a
sidewall 124a and top section 124b that are configured on the
opposing sidewall 130b of flexible element 130. A similar
configuration can be employed for the other segments 120, although
they are not shown for simplicity.
[0051] Top section 124b can comprise a top surface 125a and a
bottom surface 125b. The bottom surface 125b of top section 124b
can be sized and shaped to releasably or permanently engage with
the top surface 131 of flexible element 130. In some embodiments,
the bottom surface 125b and the top surface 131 are flat surfaces
that engage with each other. In other embodiments, either or both
of surfaces 125a and 131 can be roughened, contoured, or provided
with complementary interlocking structures to engage with each
other. In a preferred embodiment, as illustrated in FIGS. 7B, 7D,
7F, 7G, and 7I, bottom surface 125a can comprise a pin or other
element extending away therefrom that can be sized and shaped to be
received by a corresponding opening in top surface 131.
[0052] FIG. 5B is a schematic cross-sectional side view of an
embodiment of the watchband 110 illustrated in FIG. 5A in a
longitudinally wrapped, or flexed, position. Referring to both
FIGS. 5A and 5B, longitudinal axis 80 can extend through the length
of flexible element 130 and below a gap 137 configured between
adjacent sections 121a and 121b. In operation, a force can be
applied to the sidewalls 130a, 130b of flexible element 130, in the
directions shown by arrows 155 and 156. Flexible element 130 can
flex in response to the applied force, and segments 121a and 121b
can pivot about the longitudinal axis 80 in response. When segments
121a and 121b pivot about the longitudinal axis 80, the gap 137
increases or decreases in the length direction of the watch band.
For example, when segments 121a and 121b are moved in the direction
shown by arrow 156, the gap 137 increases in length. When segments
121 and 122 are moved in the direction shown by arrow 155, the gap
137 decreases in length. Note that in some embodiments, flexible
element 130 can extend into and/or through gaps 134 and 137 as
described above, such that any or all of sections 121a, 121b and
122a, 122b, are recessed within flexible element 130 (not
shown).
[0053] In some embodiments, flexible element 130 can be configured
to flex along longitudinal axis 80 and/or transverse axis 140. As
used herein, "along longitudinal axis" and "along transverse axis"
refers to the direction of longitudinal axis 80 or transverse axis
140 extending through watchband 110, regardless of whether
watchband 110 is in a wrapped or flat position.
[0054] Referring to FIG. 3, in use, a linear tension force can be
applied to watchband 110 along longitudinal axis 80, as shown by
direction arrows 165. When a force is applied in the direction
shown by arrows 165, flexible element 130 can flex (stretch) in
response, along the longitudinal axis 80, increasing the length of
gap 134 (and the distance between segments 120), and the overall
length of watchband 110.
[0055] Referring to FIG. 4, in use, a radially outwardly directed
force can be applied to watchband 110 (shown in a transversely
wrapped position) in the direction shown by direction arrows 166.
When a force is applied in the direction shown by arrows 166,
flexible element 130 can flex radially outwardly, or, as defined
above, increasing the circumference of the watch band. When
flexible element 130 flexes outwardly, the length of gap 134 (and
the distance between segments 120) can increase, and the overall
length, or as shown here, circumference, of watchband 110 can
increase.
[0056] Referring to FIG. 5A, in operation, a transverse tension
force can be applied to watchband 110 (in a substantially flat
position) along transverse axis 140, as shown by direction arrows
167. When a force is applied in the direction shown by arrows 167,
flexible element 130 can stretch laterally in response, increasing
the width of gap 137 (and the distance between sections 121a and
121b), and the overall width of watchband 110. As such, flexible
element 130 can flex or stretch along transverse axis 140.
[0057] Referring to FIG. 5B, in operation, a radially outwardly
directed force can be applied to watchband 110 (shown in a
longitudinally wrapped position) in the direction shown by
direction arrows 157. When a radially outwardly directed force is
applied in the direction shown by arrows 157, flexible element 130
can flex about longitudinal axis 80 and along transverse axis 140.
When flexible element 130 flexes radially outwardly, the length of
gap 137 (and the distance between sections 121a, 121b) can
increase, and the overall width of watchband 110 can increase.
[0058] The flexibility and/or pivotability of flexible element 130
and segments 120, as described above and shown in FIGS. 2-5B, allow
watchband 110 to flex, pivot, and twist to conform to many
different shapes and sizes, providing increased fit and comfort to
the user, some embodiments of which will be discussed below.
[0059] FIG. 6A illustrates a partial side cross-sectional view of
watchband 110 as it would be configured as worn on a wrist. In this
embodiment, watchband 110 can comprise the plurality of segments
120 carried by the flexible support 130. Axes 80 and 140 are not
shown in FIG. 6A for simplicity. The watchband 110 is shown in FIG.
6A in a longitudinally wrapped position about a central axis 50,
and comprises a central tubular channel 60 and openings 70a and 70b
for receiving a wrist therethrough. Referring again to FIG. 6A,
openings 70a and 70b comprise a diameter .phi..sub.1 and a diameter
.phi..sub.2, respectively, configured at the proximal end and
distal end, respectively, of channel 60. In this embodiment,
flexible element 130 can flex along and/or pivot about transverse
axis 140 and/or longitudinal axis 80, as described above, and
diameter .phi..sub.1 can vary relative to diameter .phi..sub.2.
[0060] In some embodiments, .phi..sub.1 can be substantially less
than (as shown) or substantially greater than (not shown) diameter
.phi..sub.2. In another embodiment, diameter .phi..sub.1 can be
substantially equal to (not shown) diameter .phi..sub.2, similar to
FIG. 1. In some embodiments, flexible element 130 can flex along
and/or pivot about transverse axis 140 and/or longitudinal axis 80,
and the cross sectional area and/or shape of opening 70a can be
substantially different from, or substantially the same as, the
cross sectional area and/or shape of opening 70b. In an embodiment,
opening 70a can comprise a roughly circular cross sectional shape,
and opening 70b can comprise a roughly elliptical cross sectional
shape (not shown). In another embodiment, opening 70a and opening
70b can be approximately the same circular cross sectional shapes,
but with different diameters .phi..sub.1 and .phi..sub.2, such that
channel 60 and flexible element 130 can form an approximately
frustroconical shape. Thus, channel 60 can vary in cross sectional
shape, diameter, and/or area along the width of watchband 110. As
such, watchband 110 can vary in cross sectional shape, diameter,
and/or area across its width while in a wrapped position. This
flexibility in cross sectional shape and/or area of openings 70a
and 70b, and channel 60, can provide increased comfort and fit to a
user of watchband 110.
[0061] FIG. 6B illustrates a partial side cross-sectional view of
watchband 110. In this embodiment, watchband 110 can comprise the
plurality of segments 120, the flexible element 130, the central
axis 50, the channel 60, and openings 70a and 70b of diameter
.phi..sub.1 and .phi..sub.2, respectively, as described above and
shown in FIG. 6A. The embodiment shown in FIG. 6B can further
comprises sections 121a and 121b, and gap 137 configured
therebetween, as described above and shown in FIGS. 2-3 and
5A-5B.
[0062] Referring again to FIG. 6B, the plurality of segments can
comprise a segment 123, wherein segment 123 can comprise side by
side sections 123a and 123b, with a gap 138 configured
therebetween. Sections 123a and 123b and gap 138 function similarly
to sections 122a and 122b and gap 137, respectively, and are
positioned on an opposing side of channel 60 therefrom. An opening
70c of diameter .phi..sub.3 can be configured to be substantially
aligned with gaps 137, 138 and to extend across channel 60. Channel
60 can comprise channel sections 60a and 60b configured on either
side of opening 70c.
[0063] In this embodiment, flexible element 130 can flex along
and/or pivot about transverse axis 140 and/or longitudinal axis 80,
as described above. When flexible element 130 flexes along and/or
pivots about transverse axis 140 and/or longitudinal axis 80,
diameters .phi..sub.1, .phi..sub.2, and .phi..sub.3 can vary
relative to each other. In some embodiments, .phi..sub.1 can be
substantially less than (as shown) or substantially greater than
(not shown) or substantially equal to (not shown) diameter
.phi..sub.2, which can be substantially less than (not shown) or
substantially greater than (as shown) or substantially equal to
(not shown) .phi..sub.3. In some embodiments, flexible element 130
can flex along and/or pivot about transverse axis 140 and/or
longitudinal axis 80 to vary the cross sectional area and/or shape
of openings 70a, 70b and 70c and channels 60a and 60b relative to
each other. In an embodiment, openings 70a and 70b can comprise an
approximately circular cross sectional shape with approximately the
same cross sectional area, and opening 70c can comprise an
elliptical shape with a substantially different cross sectional
area. As such, channels 60a and 60b can transition in shape and/or
area along the width of watchband 110.
[0064] In the illustrated embodiment, openings 70a, 70b, and 70c
can comprise an approximately circular cross sectional shape,
wherein diameters .phi..sub.1 and .phi..sub.3 are approximately
equal and .phi..sub.2 is substantially greater than .phi..sub.3 and
.phi..sub.1. This might happen as the watch slides down the
wearer's arm and rides up onto the wearer's hand. Channel section
60a can comprise an approximately cylindrical shape, and channel
section 60b can comprise an approximately frustroconical shape. As
such, channel 60 can comprise a channel section 60a that is
approximately the same cross sectional shape and area along its
width, and a channel section 60b that can vary in cross sectional
shape, diameter, and/or area along its width. Thus, watchband 110
can comprise two or more channel sections that vary independently
of each other in cross sectional shape, diameter, and/or area
across the width of watchband 110 while in a wrapped position. This
flexibility in cross sectional shape and/or area of openings 70a
and 70b, and channel 60, can provide increased comfort and fit to a
user of watchband 110.
[0065] FIGS. 7A-7B show a schematic top perspective and an exploded
top perspective view of an embodiment of a watchband 210. FIGS.
7C-7D show a schematic bottom perspective and an exploded bottom
perspective view of the watchband illustrated in FIGS. 7A-7B. FIGS.
7E and 7F show a schematic top and bottom perspective view of a
segment 221 of the watchband 210 shown in FIGS. 7A-7D. Watchband
210 can function similarly to the embodiments of watchband 110a
and/or watchband 110b described above and shown in FIGS. 2-6B. The
elements in FIGS. 7A-7F that are numbered the same as the elements
in FIGS. 1-6B function similarly as described above.
[0066] Referring to FIGS. 7A-7D, Watchband 210 comprises a
connector 212 that can function similarly to connectors 112a and/or
112b described above. In the illustrated embodiment, flexible
element 130 comprises openings 281 extending into an upper surface
131 and the lower surface 133 of flexible element 130. Openings 281
can comprise many different shapes, such as rectangular or round
holes that extend partially into the upper and lower surfaces 131,
133, with or without extending therethrough. In a preferred
embodiment, opening 281 can comprise an approximately circular hole
that extends through flexible element 130. In an even more
preferred embodiment, opening 281 can further comprise a
counterbore and/or countersink extending into surfaces 131, 133.
Opening 281 can be sized and shaped to receive a projection 284
that protrudes outwardly from the lower surface 125b of any of the
sections of segments 120, such as sections 121a-122b, as shown in
FIGS. 7E and 7F.
[0067] Referring to FIGS. 7B, 7D and 7F, projection 284 can be
configured to be received by corresponding opening 281, and to
connect segments 120 to flexible element 130 using any of the
methods described above, such as a press fit into opening 281 or
with adhesives, etc. In an embodiment, projection 284 can comprise
a non-circular shape that fits into a corresponding non-circular
opening 281, to prevent rotation of each section of segments 120
relative to flexible element 130 about an axis 260 extending
orthogonal to and through the thickness of flexible element 130,
and longitudinally through pin 284. In a preferred embodiment,
projection 284 can comprise a hollow cylinder comprising female
threads 285 extending around its inner diameter. The threads 285
can be sized and shaped to receive a screw 282 that can extend
through the lower surface 133 and opening 281 of flexible element
130. In a preferred embodiment, at least one and optionally two
pins 284 and openings 281 are employed on each section of segments
120 to prevent rotation of the section relative to flexible element
130. As such, screw 282 can mechanically attach segments 120 to
flexible element 131.
[0068] Other embodiments can be employed to mechanically attach
sections of segments 120, such as section 121a, to flexible element
131. In an embodiment shown in FIG. 7G, pin 284 can comprise an
approximately cylindrical shape with threads 284a on its outer
surface that can correspond to matching threads 281a on the inner
diameter of opening 281. In another embodiment shown in FIG. 7H, an
opening 286 can extend through the top section 124b of section
121a, and screw 282 can extend through opening 286 and be received
by threads 281a configured on the inner diameter of opening 281. In
another embodiment shown in FIG. 7I, a head 287 can be connected to
the distal end of pin 284. Head 287 can be a width greater than
opening 281 and pin 284, but small enough that it can be inserted
into opening 281. In operation, a force is applied to section 121a
in the direction shown by arrow 288, and head 284 engages with
opening 281. Opening 281 increases in width in response to the
force of head 287, and head 287 can extend through opening 281 and
the opposite side of flexible element 131. When head 287 extends
through the opposite side of flexible element 131, the width of
opening 281 returns to its quiescient state, preventing head 287
from moving in the direction opposite to arrow 288, and connecting
section 121a to flexible element 131.
[0069] In any of the embodiments described above for FIGS. 7A-7G,
openings 281 and/or 286 can be configured with or without a
countersink and/or counterbore, so that the head of screws 282 can
extend above or below the surfaces of segments 120 and/or flexible
element 130. Allowing screws 282 to extend below the surface of
segments 120 and/or flexible element 130 can provide a smoother,
more comfortable fit, when segment 120 or flexible element 130 is
worn against the user's skin, as described above. Allowing screws
to extend above the surface of segments 120 and/or flexible element
130 can improve the engagement of watchbands 110 or 210 with the
user's skin, when segment 120 or flexible element 130 is worn
against the user's skin.
[0070] FIGS. 8A and 8B comprise a schematic top view and side view
of an embodiment of a watchband 310. The elements in FIGS. 8A and
8B that are numbered the same as the elements in FIGS. 1-7H
function similarly as described above. Watchband 310 can comprise a
plurality of segments 120 and two or more flexible elements 130
that can function relative to each other, and relative to axes 80
and 140, similarly to the elastic support of watchbands 110 and 120
described above.
[0071] In this embodiment, the plurality of segments comprises
segments 321 and 322, configured adjacent to each other, similarly
to segments 121 and 122 described above. Segments 321 and 322 can
comprise sections 321a, 321b, and 322a, 322b, respectively,
configured adjacent to each other, across the midline of the band,
similarly to adjacent sections 121a, 121b, and 122a, 122b,
respectively, described above. Flexible element 130 can comprise
one or two or more longitudinal sections 130a connecting the
plurality of segments 120 along the length of watchband 310.
Longitudinal section 130a can allow the adjacent segments, such as
segments 321 and 322, to pivot about transverse axis 140 and flex
along longitudinal axis 80 as described above. Longitudinal section
130a can comprise any of a variety of flexible and preferably
elastic materials such as the materials described above for
flexible element 130.
[0072] Longitudinal connector section 130a can pass through and/or
attach to the plurality of segments 120 along the length of
watchband 310 in many different ways, such as by bonding a lower
surface of section 130a to an upwardly facing surface of segments
120, or vice versa. In another embodiment, longitudinal section
130a can comprise a plurality of individual pieces, with each piece
connected to and extending between each adjacent segment within the
plurality of segments 120. In a preferred embodiment, two
longitudinal sections 130a extend through a first and second
channel that extends through each of segments 120, such as channels
301, as shown extending through sections 321a and 321b (See FIG.
8B).
[0073] The flexible support matrix may additionally comprise a
plurality of transverse sections 130b connecting each of the
adjacent sections of the plurality of segments 120, such as
adjacent sections 321a and 321b, or sections 322a and 322b, along
the width of watchband 310. Transverse section 130b can allow the
adjacent sections, to pivot about longitudinal axis 80 and flex
along longitudinal axis 80 as described above. Transverse section
130b can comprise any of the materials described above for flexible
element 130. Transverse section 130b can connect the two rows of
sections of the plurality of segments 120 along the length of
watchband 310 in many different ways, such as by connecting a lower
surface of transverse section 130b to an upwardly facing surface of
sections 321a (and others), or vice versa. In another embodiment,
transverse section 130b can comprise a plurality of individual
pieces, with each piece connected to and extending between each
adjacent section within the plurality of segments 120. In a
preferred embodiment, each transverse section 130b extends through
a channel that extends through at least a portion of each of
segments 120, such as channel 302, as shown extending through
sections 321a and 321b (See FIG. 8B).
[0074] FIG. 9 shows a schematic side cross-sectional perspective
view of an embodiment of a watchband 410. Watchband 410 can
function similarly to watchbands 110, 210, and 3 10, described
above. Watchband 410 can comprise a first plurality of segments 120
connected to a first surface of flexible element 130, functioning
similarly to that described above. The first plurality of segments
120 can comprise segments 421 and 422, comprising sections 421a,
421b and sections 422a, 422b, that function similarly to segments
121, 122 and sections 121a, 121b and sections 122a, 122b described
above. In this embodiment, each segment, such as illustrated
segments 421 and 422, can comprise a third row of sections, such as
illustrated sections 421c and 422c, extending across the width of
watchband 410, configured to pivot about a second longitudinal axis
80. Watchband 410 can also comprise a second plurality of segments
420, such as segments 423 and 424, connected to the surface of
flexible element 130 opposite to segments 120. The second plurality
of segments 420 can function similarly to the first plurality of
segments 120, but will pivot in the opposite direction about axis
140 and axis 80. Segments 423 and 424, and the other segments in
the plurality of segments 420, can comprise sections extending
across the width of watchband 410, such as sections 423a-c and
424a-c. Sections 423a-c and 424a-c function similarly to sections
421a-c and 422a-c, but pivot in the opposite direction about axes
80 than sections 422a-c and 421a-c, respectively.
[0075] Although the invention has been disclosed in the context of
certain embodiments and examples, it will be understood by those
skilled in the art that the invention extends beyond the
specifically disclosed embodiments to other alternative embodiments
and/or uses and obvious modifications and equivalents thereof
Accordingly, the invention is not intended to be limited by the
specific disclosures of preferred embodiments herein.
