Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims the benefit of U.S.
Provisional Patent Application No. 61/305,267 filed on Feb. 17,
2010 and U.S. Provisional Patent Application No. 61/419,105 filed
on Dec. 2, 2010, the contents of which are incorporated herein by
reference in their entirety.
FIELD
[0002] The present invention is related to a device for easily and
unobtrusively winding, storing, and protecting cords and/or
cables.
BACKGROUND
[0003] Many devices have a cord or cable associated with the
device. For example, kitchen appliances such as toasters, coffee
makers, and blenders all have a power cable for the transmission of
electrical power. In the digital age, most audio-visual devices
have a cord or cable. For example, users use headphones or earbuds
with their MP3 players and smart phones. Moreover, the cost to
replace damaged or broken cords/cables/headphones is increasingly
expensive. Although there are a variety of winders available to
organize and store cords and cables, these conventional devices
fail to be user friendly and/or fail to adequately wind and store
the cord or cable. As such, cable management, including organizing,
storing, preventing tangling, and protecting cords/cables, remains
a continued source of frustration for many people. Accordingly,
there is a need for devices that organize and/or make cords easier
to use and store.
SUMMARY
[0004] It is to be understood that the present invention includes a
variety of different versions or embodiments, and this Summary is
not meant to be limiting or all-inclusive. This Summary provides
some general descriptions of some of the embodiments, but may also
include some more specific descriptions of other embodiments.
[0005] In accordance with one or more embodiments, winders of
various size and characteristics are provided to wind and store a
variety of cords or cables and to operate "automatically." As used
herein, "automatically" means the winder device in its ready state
can operate without turning a crank or handle in order to rotate a
winding spool. In use, a folded portion of a cable or cord is
engaged around a grasping member, such as a hook. Thereafter, the
cord/cable is pulled slightly to disengage a pawl from a spool, and
a button is then pushed releasing a spring for winding the
cord/cable around the spool. When the two ends of the cord/cable
reach the entry point, the refraction stops. To extract the
cord/cable, the user pulls the two portions of the cord/cable,
either to a desired length or all the way until the cord/cable
releases from the winder. Alternatively, a locking hook may be used
to lock the cable to the hook so that the cable remains attached to
the winder when fully unwound. As the cord/cable is extracted, the
spring is re-loaded for the next use. Accidental spin-out is
prevented by locking the winder device in its loaded state.
Accordingly, a winder device substantially as herein shown and
described is provided.
[0006] In at least one embodiment, a device for winding a cord is
provided. The cord is bendable to form a looped portion.

DETAILED DESCRIPTION
[0232] One or more embodiments of the one or more inventions
described herein include one or more devices, assemblies and/or
methods related to a winder device. A winder device in accordance
with at least one embodiment described herein can be used to
organize, store, and/or protect cables, such as wire rope, and
electrical cords. One or more embodiments of the winder devices
described herein have application for audio equipment, such as
stereophones, headsets, earphones, earbuds, etc.
[0233] Referring now to FIGS. 1A-10C, one embodiment of the one or
more present inventions is shown. In at least the embodiment
depicted, the winder device 100 generally includes back and front
housings 104 and 108, back and front spool sides 112 and 116, a
spool 120, a drive spring 124, a pawl 128, a button 132, button
spring 136, and a button plate 140.
[0234] With particular reference now to FIGS. 2A-2H, the back
housing 104 of at least one embodiment is shown. The back housing
104 generally includes a front interior surface 200, a back surface
204, and top and bottom struts 208 and 212 adapted to interconnect
the back housing 104 and the front housing 108. In at least one
embodiment, the top and bottom struts 208 and 212 are integrally
formed with the back housing 104. The top and bottom struts 208 and
212 may include at least one bracket 216 and at least one bracket
receiving space 220 adapted to mate with corresponding elements on
the front housing 108 such that the back and front housings 104 and
108 are interconnected by a press or interference fit. However, any
number or combinations of fastening devices may be used to
interconnect the back housing 104 and the front housing 108,
including pins, screws, rivets, retaining rings, clamps, threaded
fasteners, or glues and other adhesives.
[0235] In at least one embodiment, the front interior surface 200
of the back housing 104 also includes a spool side area 224 adapted
to abut at least a portion of the back spool side 112. In some
embodiments, the spool side area 224 is recessed such that at least
a portion of the back spool side 112 sits within the spool side
area 224. In at least one embodiment, the spool side area 224 is
disc-shaped. Furthermore, in at least one embodiment, the spool
side area 224 includes a circular ledge 228 positioned within at
least a portion of the spool side area 224. The ledge 228 is
adapted to facilitate movement of the back spool side 112 within
the back spool side area 224. The ledge 228 may also facilitate the
placement or positioning of the back spool side 112 in the spool
side area 224.
[0236] In at least one embodiment, the front interior surface 200
of the back housing 104 further includes an axle 232 adapted to
receive a portion of the spool 120. The axle 232 of at least one
embodiment is cylindrical in shape and is substantially rigid.
Moreover, in at least one embodiment, the axle 232 is formed
integral with the back housing 104. However, in other embodiments,
the axle may be formed separately from the back housing and
subsequently fastened thereto using a variety of known fastening
mechanisms. The axle 232 may also include a spring anchor 236 for
securing the drive spring 124 to the axle 232. In at least one
embodiment, the spring anchor 236 is a longitudinal opening that
spans the length of the axle 232 and bifurcates at least a portion
of the axle 232. In other embodiments, the spring anchor 236 may be
a longitudinal groove (or other receiving portion) that spans at
least a portion of the length of the axle 232. The axle 232 remains
fixed (or otherwise non-rotatable) while under loaded and unloaded
conditions. In at least one embodiment, the axle 232 is made from
Acrylonitrile Butadiene Styrene ("ABS"); however, the axle 232 may
be made from a variety of other materials that are durable, low
friction, and wear resistant, such as a metal, or other hard
plastic.
[0237] In at least one embodiment, the front interior surface 200
of the back housing 104 further includes a plurality of spokes 240
positioned adjacent to the spool side area 224 and the axle 232. In
at least one embodiment, the plurality of spokes 240 extend
radially outward from the axle 232 toward the spool side area 224.
The plurality of spokes 240 decrease the surface contact between
the drive spring 124 and back housing 104 and further serve as
structural reinforcements for the back housing 104.
[0238] In at least one embodiment, the back surface 204 of the back
housing 104 includes a surface treatment or material, such as a
non-slip, grippable, traction providing, shock absorbing, drop
resistant, or other impact resistant material (not shown) to
facilitate a user's handling or manipulation of the winder device
100 and/or to protect the winder device 100 from being damaged.
Similarly, in still other embodiments, the back surface 204
includes a decorative or aesthetic decal or design to enhance the
marketability of the device.
[0239] In at least one embodiment, the back housing (including the
aforementioned features) 104 are formed integrally. For example,
the back housing 104 may be formed using an injection molding or
other cost effective manufacturing process or processes.
[0240] Referring now to FIGS. 3A-3F, the spool 120 of at least one
embodiment of the present inventions is shown. The spool 120 of
this embodiment has a substantially cylindrical configuration, an
outer surface 300, a front surface 304 a back surface 308, and a
plate 312. The plate 312 is generally positioned to separate the
front surface 304 from the back surface 308 and\or to prevent the
drive spring 124 from interfering with the pawl 128. In at least
one embodiment, the spool 120 has a diameter D.
[0241] Referring specifically now to FIGS. 3A-3B, the plate 312
includes an aperture 316 adapted to receive a portion of the axle
232 associated with the back housing 104. In one embodiment, the
aperture 316 is sized to have at least some clearance such that the
spool 120 may easily slide on and rotate about the axle 232. In
other embodiments, ball bearings or other friction reducing
materials may be provided at a contact point of the aperture 316
and the axle 232.
[0242] Referring now to FIGS. 3B and 3F, the back surface 308 of at
least one embodiment of the spool 120 includes a back edge 320 and
a hollow portion 324 therein. The back edge 320 includes a first
set of holes 328 for selectively receiving a plurality of
corresponding projections 416 positioned on the back spool side 112
(discussed below). Moreover, any number of fastening means may be
included on the back edge 320 to selectively and/or removably
interconnect the back surface 308 of the spool 120 to the first
face 400 of the back spool side 112, such as slots or channels.
[0243] The hollow portion 324 is adapted to receive the drive
spring 124. The hollow portion 324 substantially encloses the drive
spring 124; however, one of skill in the art will appreciate that
in other embodiments, the hollow portion 324 may partially enclose
the drive spring 124. The hollow portion 324 helps maintain the
shape of the drive spring 124 and also protects the drive spring
124 from distortion and/or damage.
[0244] In addition, in at least one embodiment the back surface 308
of the spool 120 also includes a spring engaging member adapted to
engage the drive spring 124. The spring engaging member of one
embodiment is a spring slot 332 that extends from the back edge 320
of the back surface 308 longitudinally along the outer surface 300
to some length or depth. The length of the spring slot 332 may vary
depending on the type or size of the drive spring 124 that is used
for a particular winder.
[0245] Referring now to FIGS. 3A and 3E, in at least one
embodiment, the front surface 304 includes a front edge 336 that
has a second set of holes 340 and teeth 344. The second set of
holes 340 are adapted to receive a plurality of projections 416
positioned on the front spool side 116 (discussed below). Any
number of interconnecting mechanisms, such as slots or channels,
may be included on the front edge 336 to selectively and removably
interconnect the front surface 304 of the spool 120 to the first
face 400 of the front spool side 116.
[0246] The teeth 344 generally project radially inward (i.e.,
toward the center of the spool 120) and are sized and shaped to
engage at least a portion of the pawl 128. The teeth 344 are
oriented at an angle .alpha. in order to reduce and/or prevent
winder spin-out. Accidental spin-out is undesirable because a user
has to then manually re-load the drive spring 124 before the
cord/cable may be wound. As such, the engagement between the spool
120 and the pawl 128 is configured such that the drive spring 124
is maintained in a loaded condition until the user is ready to wind
the cord/cable (thereby unloading the drive spring). In order to
achieve the desirable spool/pawl engagement, the teeth 344 are
properly angled to engage and maintain the engagement (i.e.,
minimize slip) with the pawl teeth 616. In at least one embodiment,
this engagement is achieved by orienting the teeth 344 at an angle
.alpha. that ranges from about 25 degrees to about 45 degrees. In a
preferred embodiment, the teeth 344 are oriented at an angle
.alpha. of about 37 degrees.
[0247] Referring back to FIGS. 3A-3F, the outer surface 300 of the
spool 120 includes a plurality of grasping members. In at least one
embodiment, the grasping members are hooks 348 adapted to
selectively engage a portion of a cord, cable, or other object to
be wound with the winding device 100. The number of hooks 348
positioned on the outer surface 300 of the spool 120 may vary
depending on a number of variables, such as size and the
graspability of the object. Moreover, the grasping members are not
limited to hooks and may include a variety of configurations,
geometries, and superficial features that are adapted to assist
with grasping and/or selectively retaining the cord/cable.
Consequently, the height H of the spool 120 may vary depending on
the exact configuration of the grasping members. In some
embodiments, it may be desirable to include locking hooks to lock
the cord/cable to the hook so that the cord/cable remains attached
to the winder device when fully unwound.
[0248] In at least one embodiment, the spool 120 is manufactured as
an integral piece using any number of conventional manufacturing
processes, such as injection molding, and is made at least
partially from Delrin, or other similar materials. In other
embodiments, the grasping members may be individually and/or
selectively interconnected to the outer surface 300 of the spool
120, depending on the application.
[0249] Referring now to FIGS. 4A-4E, a spool side of one embodiment
is shown. In at least one embodiment, the winder device includes
two spool sides, adapted for positioning on either side of the
spool. In other embodiments, the winder device has no spool sides.
In yet other embodiments, the winder device has only one spool
side. In still yet other embodiments, the spool sides are formed
integrally with the spool.
[0250] In at least one embodiment, the winder device 100 includes a
back spool side 112 and a front spool side 116. The back and front
spool sides 112 and 116 may be substantially identical parts. As
such, the spool side shown in FIGS. 4A-4E, can be either the back
spool side 112 or the front spool side 116. Because the back and
front spool sides 112 and 116 are substantially identical, the
number of different component parts that need to be manufactured
decreases and the throughput of the manufactured parts increases.
However, in some embodiments, it may be desirable to have back and
front spool sides 112 and 116 that are not substantially identical
parts. For example, the back and front spool sides 112 and 116 may
have different interconnecting mechanisms that allow the spool 120
to be selectively removable from the back and front spool sides 112
and 116.
[0251] In at least one embodiment, the back and front spool sides
112 and 116 are adapted to interconnect with the spool 120. The
back and front spool sides 112 and 116 have a first face 400, a
second face 404, an outer diameter 408, an inner diameter 412, and
a substantially planar torus shape. The first face 400 of back
spool side 112 is adapted to interconnect to the back surface 308
of the spool 120 and the second face 408 of the back spool side 112
is adapted to abut the spool side area 224 of the back housing 104.
Similarly, the first face 400 of the front spool side 116 is
adapted to interconnect to the front surface 304 of the spool 120
and the second face 404 of the front spool side 116 is adapted to
abut the spool side area 732 of the front housing 108.
[0252] In addition, in at least one embodiment, a plurality of
projections 416 positioned on the first face 400 of the back and
front spool sides 112 and 116 are positioned proximate to the inner
diameter 412. The plurality of projections 416 may be spaced,
equidistantly, non-equidistantly, or in any number of other
configurations, around the perimeter of the inner diameter 412. In
at least one embodiment, the plurality of projections 416 have a
dowel pin or cylindrical rod shape. The plurality of projections
416 are adapted to be received by corresponding fastening means,
i.e., in corresponding holes on the front and back surfaces 304 and
308 of the spool 120. Moreover, the plurality of projections 416
may have various shapes and/or geometry, so long as the spool 120
has corresponding or mating interconnection means.
[0253] The back and front spool sides 112 and 116 may be made from
any number of materials, including thermoplastics, such as Delrin
having high stiffness, low friction, and good dimensional
stability. Moreover, the spool sides 112 and 116 may be
manufactured using a number of methods and/or processes, including
injection molding.
[0254] Referring now to FIGS. 5A-5C, a biased member is shown. In
at least one embodiment, the biased member is a drive spring
(mainspring) 124. However, the biased member may be a coil spring
in a biased condition. The drive spring 124 includes a first end
tab 500 and a second end tab 504. The first end tab 500 is adapted
to engage the spring anchor 236 on the axle 232, and the second end
tab 504 is adapted to engage the spring slot 332 on the spool 120.
In at least one embodiment, the first end tab 500 further includes
an approximately 90 degree bend that interconnects the drive spring
124 to the axle 232 and the second end tab 504 includes a 180
degree or substantially U-shaped bend that interconnects the drive
spring 124 to the spool 120. The width W of the drive spring 124 is
designed to fit within at least a portion of the hollow portion 324
of the spool 120 and is made of a strip of metal ribbon. The drive
spring 124 may be made of a strip of blue steel, a steel alloy, a
carbon steel alloy, other metal alloys, or combinations thereof.
Moreover, in at least one embodiment, in a non-compressed (or
un-stressed) state, the drive spring 124 includes about ten turns
and is adapted to provide at least about 0.5 inch-pounds of torque,
and more preferably about 0.8 inch-pounds of torque. As such, the
drive spring 124 is the power source for the winder device 100. In
another embodiment, the biased member may be an elastic material
such as `bungee` cord.
[0255] Referring now to FIGS. 6A-6H, a pawl 128 of at least one
embodiment is shown. The pawl 128 generally includes an outer
surface 600, a front surface 604, a back surface 608, and an
aperture 612 between the front and back surfaces 604 and 608. The
front surface 604 of the pawl 128 is adapted to abut at least a
portion of the button 132, and the back surface 608 of the pawl 128
is adapted to abut at least a portion of the spool 120, in at least
one embodiment.
[0256] The outer surface 600 has pawl teeth 616 on a portion
thereof. The pawl teeth 616 are adapted to selectively and operably
engage the teeth 344 on the front edge 336 of the spool 120. The
number of pawl teeth 616 may vary depending on a variety of
factors. In at least one embodiment, the outer surface 600 also
includes an offset or recessed portion 620. Incorporation of a
recessed portion 620 may be advantageous for winder devices where
additional clearance between the pawl 128 and the spool 120 is
desired.
[0257] Referring specifically now to FIGS. 6A and 6G, the front
surface 604 of at least one embodiment includes a projection 624
adapted to engage a portion of the button 132 (discussed below). As
shown in FIG. 6A, the projection 624 is D-shaped. In alternative
embodiments, the projection 624 may have a number of different
configurations, including cylindrical, conical, polygonal, or an
"O" shaped projection. In some embodiments, the front surface 604
has more than one projection. The position of the projection 624
may vary depending on the size of the pawl 128 and the
configuration of the front housing 108, among others. Moreover, in
at least one embodiment, the projection 624 has a surface treatment
such as a texturizing coating (not shown) on at least a portion
thereof to enhance the surface contact between the projection 624
and the button 132.
[0258] Referring now to FIGS. 6A and 6B, the aperture 612 is
adapted to receive a portion of the front housing 108. More
particularly, the aperture 612 is adapted to receive a projection
728 on the back interior surface 704 of the front housing 108.
[0259] Referring now to FIGS. 7A-7H, the front housing 108 is
shown. The front housing 108 of at least one embodiment generally
includes a front surface 700, a back interior surface 704, an
aperture 708 therethrough, and top and bottom struts 712 and 716
adapted to interconnect the front housing 108 and the back housing
104. In at least one embodiment, the top and bottom struts 712 and
716 are integrally formed with the front housing 108. The top and
bottom struts 712 and 716 may include at least one bracket 720 and
at least one bracket receiving space 724 adapted to mate with
corresponding elements on the back housing 104 such that the front
and back housings 108 and 104 are interconnected by a press or
interference fit. In alternative embodiments, various fastening
mechanisms are used to interconnect the front and back housings 108
and 104. In another embodiment, in lieu of the top and bottom
struts 712 and 716, the front and back housings 108 and 104 are
connected with a centered bracket (not shown). In still another
embodiment, the front housing 108 includes one bracket that is
adapted to connect to the back housing 104. In yet another
embodiment, the axle 232 interconnects the front and back housings
108 and 104 and no brackets need be provided.
[0260] In at least one embodiment, the back interior surface 704 of
the front housing 108 is adapted to engage the pawl 128. The back
interior surface 704 includes a projection 728 to interconnect with
the aperture 612 of the pawl 128. Depending on the configuration of
the pawl 128, the size, shape, and position of the front housing's
projection 728 may vary. In at least one embodiment, the projection
728 is cylindrical and proximate the aperture 708 of the front
housing 108. The back interior surface 704 of the front housing 108
may also include a spool side area 732 adapted to abut at least a
portion of the front spool side 116. In some embodiments, the spool
side area 732 is recessed such that at least a portion of the front
spool side 116 sits within the spool side area 732. Moreover, the
portion of the back interior surface 704 that is proximate the
spool 120 may optionally be recessed to ensure that the spool 120
has sufficient clearance to rotate and/or to make the winder device
100 lighter.
[0261] Referring now to FIGS. 7A-7B and 7G-7H, the aperture 708 of
the front housing 108 of at least one embodiment is adapted to
allow at least a portion of the pawl 128 to pass at least partially
therethrough. The shape of the aperture 708 may vary depending on a
variety of factors, such as the size of the winder device, size of
the pawl, etc. In at least one embodiment, the aperture 708 has a
generally kidney-bean shape. In operation, the position of the pawl
128 in the aperture 708 varies depending on the position of the
button 132.
[0262] Referring specifically now to FIGS. 7A and 7G, in at least
one embodiment, the front surface 700 of the front housing 108
generally includes a button receiver 736. The button receiver 736
is generally adapted to receive the button 132 and the button plate
140. The button receiver 736 is preferably positioned such that the
aperture 708 passes therethrough. In some embodiments, the button
receiver 736 is recessed relative to the front surface 700 of the
front housing 108. The size and shape of the button receiver 736
may vary depending on the size and shape of the button 132 and
button plate 140. In at least one embodiment, the button receiver
736 has a clip 740 adapted to interconnect to a portion of the
button 132. The clip 740 in at least one embodiment is sized and
shaped to engage the button's spring receiver 916. The front
surface 700 of the front housing 108 may also include a direction
indicator 744. In an exemplary embodiment, the direction indicator
744 is positioned on the button receiver 736. The direction
indicator 744 helps facilitate use of the winder device 100.
Furthermore, the front surface 700 of the front housing 108 may
include an ornamental design or feature (not shown), including a
product name, brand, logo, design, or decorations such as
rhinestones. An ornamental design or feature may be desirable for
brand recognition and/or marketing purposes.
[0263] The button plate 140 of at least one embodiment is shown in
FIGS. 8A-8H. The button plate 140 generally includes a front face
800, a back face 804, and a window 808 therebetween. The back face
804 of the button plate 140 is adapted to interconnect to the front
housing 108. In at least one embodiment, the back face 804 of the
button plate 140 is adapted to engage at least a portion of the
button receiver 736. The back face 804 of the button plate 140 may
be snap-fit, press-fit, glued, or otherwise positioned at least
partially within the button receiver 736 of the front housing 108.
As such, depending on the desired interconnection, the back face
804 of the button plate 140 may include additional fastening means,
including screws, pins, and glues, among others. In some
embodiments, when the button plate 140 is received within the
button receiver 736, the button plate 140 is substantially flush
with the front surface 700 of the front housing 108, whereas in
other embodiments, the button plate 140 is raised relative to the
front surface 700 of the front housing 108.
[0264] In at least one embodiment, the back face 804 of the button
pate 140 is also adapted to engage at least a portion of the button
132. For example, the back face 804 of the button plate 140 may
include at least one bracket receiving slot 812 for engaging the
button 132. In at least one embodiment, the back face 804 has two
bracket receiving slots 812, one on each longitudinal side of the
button plate 140. The bracket receiving slots 812 are adapted to
receive corresponding brackets 908 on the button 132. In at least
one embodiment, the bracket receiving slots 812 are larger than the
button brackets 908 such that the button brackets 908 may slide
within the bracket receiving slots 812 so that the button 132 can
move in a translational direction within the window 808.
[0265] In at least one embodiment, the window 808 is positioned
such that at least a portion of the front face 900 of the button
132 extends at least partially therethrough. In some embodiments,
when the button 132 is aligned in the window 808, the button 132 is
substantially flush with the window 808 of the button plate 140. In
other embodiments, the button 132 extends beyond the front face 800
of the button plate 140.
[0266] Referring now to FIGS. 9A-9H, the button 132 of at least one
embodiment is shown. The button 132 generally includes a front face
900 and a back face 904 and is adapted to interconnect to the
button plate 140 and the front housing 108.
[0267] In at least one embodiment, the back face 904 of the button
132 abuts at least a portion of the button receiver 736 on the
front housing 108. Brackets 908 may be used to at least partially
retain the button 132 within the button receiver 736. In at least
one embodiment, the button 132 has two brackets 908, one on either
side of the back face 904 of the button 132, that are adapted to be
received in the bracket receiving slots 812 of the button plate
140. As such, the button 132 is slidably engaged with the button
plate 140 and the button 132 is able to move within the button
receiver 736.
[0268] The back face 904 of the button 132 is also generally
adapted to engage at least a portion of the pawl 128. In at least
one embodiment, the back face 904 includes a pawl receiver 912. The
pawl receiver 912 may be shaped to correspond to the shape of the
pawl's projection 624. In at least one embodiment, the pawl
receiver 912 is substantially D-shaped (to interconnect to a
D-shaped projection 624 on the pawl 128). In other embodiments, the
pawl receiver 912 is substantially O-shaped, polygonally shaped, or
conically shaped to receive a corresponding pawl projection.
[0269] In at least one embodiment, the back face 904 of the button
132 also includes a spring receiver 916 configured as a
longitudinal slot. The spring receiver 916 is adapted for receiving
the clip 740 on the front surface 700 of the front housing 108. The
spring receiver 916 is also adapted to receive a biased member. An
exemplary biased member is illustrated in FIGS. 10A-10C. In at
least one embodiment, the biased member is a coil or helical button
spring 1000. The button spring 1000 may be made from a number of
materials. The button spring 1000 is adapted for positioning within
the spring receiver 916. As such, the clip 740 is proximate the
button spring 1000. The button spring 1000 of at least one
embodiment is adapted to store and release a sufficient amount of
energy such that when the button 132 is moved from a first position
of use to a second position of use, the button spring 1000 is
loaded (i.e., compressed against the clip 740) and when the button
132 is moved from the second position of use to the first position
of use, the button spring 1000 is unloaded (i.e., expands away from
the clip 740).
[0270] The front face 900 of the button 132 may include surface
features to assist a user's manipulation of the button 132. For
example, in at least one embodiment, the front face 900 has a
grippable or textured surface (not shown) such that users of
varying age and dexterity may slidably move the button 132.
[0271] Although an exemplary winder device 100 is depicted in FIGS.
1A-10C, one of skill in the art can appreciate the winder device
100 may be sized up or down depending on the application and the
type of cord/cable used. For example, for extension cords, power
cords or other larger/longer/thicker cords, the winder device may
require a large size whereas, for kitchen appliances and computers,
the winder device may require a medium size, and whereas, for
headphone and cellular phones, the winder device may require a
small size. That is, the size of the winder device may be designed
large enough to store and protect the type of cable/cord while also
small enough to be non-bulky and unobtrusive.
[0272] Referring now to FIGS. 11A-11C, the operation of at least
one embodiment of the winder device 100 is shown. FIGS. 11A and 11B
show that as a user pulls the cord/cable 100 associated with the
winder out of (or at least partially out of) the winder device 100,
the spool 120 rotates. When the spool 120 rotates, the spool 120
engages the pawl 128 and torque is transmitted to the drive spring
124. As such, the rotation of the spool 120 causes the drive spring
124 to wind/spiral tighter, which loads the drive spring 124. In
the loaded condition, the drive spring 124 stores a certain amount
of energy. Moreover, as the spool 120 rotates, the teeth 344 on the
spool 120 selectively engage the pawl teeth 616 such that when the
user stops pulling on the cord/cable 1100, the pawl teeth 616 lock
the position of the spool 120 in place. Because of the engagement
between the pawl teeth 616 and spool's teeth 344, the spool 120 is
held in place and is maintained in a loaded state, which prevents
the drive spring 124 from releasing its energy.
[0273] FIG. 11C shows how the cable/cord 1100 is wound into the
winder device 100. When the user is ready to wind the cable/cord
1100 onto the spool 120, the user loops the cable/cord 1100 around
one of the grasping members (hooks in the embodiment shown) and
pulls slightly to exert some force against the cable/cord 1100 to
at least partially disengage the pawl teeth 616 from the spool 120.
Once the pawl teeth 616 have disengaged, the user is able to move
the button 132 from a first position of use to a second position of
use (by moving the button up in the embodiment shown), which moves
the pawl teeth 616 away from the spool's teeth 344. Once the pawl
128 and the spool 120 are disengaged, the drive spring 124 is able
to release and return to an unloaded state. Unloading the drive
spring 124 causes the spool 120 to spin and wind the cable/cord
1100 into the winder device 100. One of skill in the art will
appreciate that having both ends of the cord/cable at one entry
point (rather than each end of the cord/cable coming out of
different entry points) is desirable in that both ends of the cord
can be quickly accessed.
[0274] It is desirable to be able to keep the drive spring in a
loaded state so that the spool is ready to wind the cable/cord when
the user is ready. As such, it is desirable to prevent accidental
spin-out (or unloading) of the drive spring. In at least one
embodiment, accidental spin-out is prevented by preventing the
button from moving when a cord/cable is not engaged with the winder
device. That is, the button cannot move from a first position of
use to a second position of use unless and until a cord is engaged
with the spool and the user pulls slightly on the cord while moving
the button. A user who completely removes his or her headphones
from the winder device is prevented from accidentally unloading the
drive spring because he or she may not move the button to a second
position of use until the cord/cable has been re-engaged with the
spool's grasping members and the user has pulled slightly on the
cord/cable. Similarly, a user who partially removes his or her
earbuds from the winder device is prevented from accidentally
unloading the drive spring because he or she has to pull slightly
on the cord/cable before he or she may move the button to a second
position of use. Preventing accidental spin-out is highly desirable
for the user who, for example, takes his or her earphones out of
the winder device and then places the winder device in a backpack,
briefcase, or purse while he or she is using the earphones. In this
example, the winder device will not accidentally unload while in
the backpack, briefcase, or purse and the winder device is ready to
wind the cord/cable when the user is ready to. If, however, the
drive spring does spin-out or unload accidentally, the user may
simply reload the drive spring by manually rotating the spool.
[0275] Referring now to FIGS. 12-23, another embodiment of the
present inventions is illustrated. To draw a few exemplary and
non-limiting distinctions between the winder device 100 of at least
one embodiment (discussed above) and the winder device 1200 of at
least another embodiment (discussed below), one will notice that in
the embodiment shown in FIGS. 12-23, the winder device 1200
includes front and back cover plates. One of skill in the art will
appreciate that depending on the application or use of the winder,
it may be desirable to have or not have front and back cover
plates. For example, when a lower profile winder is desirable, the
winder device 100 without cover plates may be advantageous.
Alternatively, when a more robust winder is desired, the winder
device 1200 having cover plates may be advantageous. To further
contrast the at least two embodiments, the winder device 100 has an
axle 232 that is integral to the back housing 104 whereas the
winder device 1200 has an axle 1220 separate from the back cover
plate 1204 and back housing 1212. Again, depending on the
particular application or use of the winder device, it may be
desirable for the winder device to have fewer individual components
such that the efficiency of the manufacturing and/or assembly
processes are increased. In contrast, it may be desirable to have a
separate axle if the cable/cord to be wound requires a stronger
axle.
[0276] Referring now to FIG. 12, an exploded view illustrates at
least another embodiment of a winder device 1200. The winder device
1200 of at least this embodiment generally includes back and front
cover plates 1204 and 1208, back and front housings 1212 and 1216,
an axle 1220, back and front spool sides 1224 and 1228, a spool
1232, a drive spring 1236, a pawl 1240, a button 1244, and a button
spring 1248.
[0277] With reference now to FIGS. 13A-13H, the back cover plate
1204 of at least one embodiment is shown. The back cover plate 1204
generally includes front surface 1300 and a back surface 1304. The
front surface 1300 includes a first recessed portion 1308. In the
embodiment shown, the first recessed portion 1308 is disc-shaped
(having a flat circular shape). The first recessed portion 1308 is
adapted to receive a mating portion on the back housing 1212. In at
least one embodiment, the front surface 1300 also includes a second
recessed portion 1312 adapted to cover a portion of the axle 1220.
In the embodiment shown, the second recessed portion 1312 is
circular and positioned in substantially the center of the back
cover plate 1204. However, one of skill in the art will appreciate
that the shape and position of the second recessed portion 1312 may
vary depending on the shape and position of the axle 1220.
[0278] The back cover plate 1204 also includes top and bottom
brackets 1316 and 1320. In at least one embodiment, the top and
bottom brackets 1316 and 1320 are integrally formed with the back
cover plate 1204. For example, in at least one embodiment, the back
cover plate 1204 includes integral top and bottom brackets 1316 and
1320 and is manufactured using an injection molding process. The
top and bottom brackets 1316 and 1320 are adapted to fasten the
back cover plate 1204 to the back housing 1212. In at least one
embodiment, the top and bottom brackets 1316 and 1320 mechanically
interconnect to the back housing 1212 by a snap fit. The top and
bottom brackets 1316 and 1320 may include a raised lip 1324 to
enhance the snap fit design. One of skill in the art will
appreciate that any number of fasteners may be used to interconnect
the back cover plate 1204 and the back housing 1212, such as a
screws, rivets, pins, retaining rings, clamps, threaded fasteners,
or glues and other adhesives. In at least one embodiment, the back
surface 1304 of the back cover plate 1204 further includes a
non-slip, grippable, traction providing, or other surface treatment
or material (not shown) to facilitate a user's handling of the
winder device 1200. Similarly, depending on the application, it is
envisioned that the back surface 1304 of the back cover plate 1204
includes shock absorbing, drop resistant, or other impact resistant
material (not shown) to further protect the winder device 1200 from
being damaged.
[0279] Referring now to FIGS. 14A-14H, the back housing 1212 of at
least one embodiment is depicted. The back housing 1212 generally
includes a front surface 1400 and a back surface 1404. The back
surface 1404 of the back housing 1212 (see FIGS. 14B and 14H) is
adapted to interconnect with the front surface 1300 of the back
cover plate 1204. In at least one embodiment, the back surface 1404
of the back housing 1212 generally includes a first raised portion
1408 that is shaped to mate with or otherwise engage the first
recessed portion 1308 on the front surface 1300 of the back cover
plate 1204. In at least one embodiment, the first raised portion
1408 is disc-shaped (having a flat circular shape). The back
surface 1404 of at least one embodiment also includes a second
raised portion 1412 having an aperture 1416 adapted to allow the
shaft portion 1508 of the axle 1220 to pass therethrough. The
second raised portion 1412 may include, among others, an inner
diameter 1420 and an outer diameter 1424. In at least one
embodiment, the inner diameter 1420 is substantially "D" shaped (to
receive the planar edge 1528 of the substantially circular head
portion 1512 of the axle 1220), whereas the outer diameter 1424 is
substantially circular in shape. One of skill in the art will
appreciate that the shape of the inner diameter 1420 may vary
depending on the shape and configuration of the axle 1220. In at
least one embodiment, the first and second raised portions 1408 and
1412 (on the back surface 1404 of the back housing 1212) are
adapted to engage the first and second recessed portions 1308 and
1312 (on the front surface 1300 of the back cover plate 1204) and
selectively interconnect the back housing 1212 to the back cover
plate 1204.
[0280] Referring specifically to FIGS. 14A and 14G, the front

durable, low friction, and wear resistant.
[0287] Referring now to FIGS. 16A-16E, the spool 1232 of at least
one embodiment of the present invention is shown. The spool 1232
may have a generally cylindrical configuration and in one
embodiment includes an outer surface 1600, a front surface 1604, a
back surface 1608, and a plate 1612 positioned therebetween
(separating the front surface 1604 from the back surface 1608). In
at least one embodiment, the spool 1232 has a diameter D.
[0288] In the embodiment shown, the plate 1612 includes an aperture
1616 adapted to receive the shaft portion 1508 of the axle 1220. In
one embodiment, the aperture 1616 is sized to have at least some
clearance such that the spool 1232 may easily slide on and rotate
about the axle 1220.
[0289] In at least one embodiment, the back surface 1608 includes a
back edge 1620 and a hollow portion 1624 therein. The back edge
1620 includes a first set of holes 1628 for receiving a plurality
of projections 1716 that are positioned on the back spool side 1224
(discussed below). One of skill in the art will appreciate that any
number of interconnecting means may be included on the back edge
1620 to selectively and/or removably engage and interconnect the
back surface 1608 of the spool 1232 to the first face 2408 of the
back spool side 1224.
[0290] In at least one embodiment, the hollow portion 1624 is
adapted to receive the drive spring 1236. The hollow portion 1624
substantially encloses the drive spring 1236 in at least one
embodiment; however, one of skill in the art will appreciate that
in other embodiments, the hollow portion 1624 may partially enclose
the drive spring 1236. The hollow portion 1624 protects the drive
spring 1236 from distortion and/or damage.
[0291] Referring specifically now to FIGS. 16B and 16F, in at least
one embodiment the back surface 1608 of the spool 1232 also
includes a spring engaging member. The spring engaging member of
one embodiment is a spring slot 1632 that extends from the back
edge 1620 of the back surface 1608 longitudinally along the
cylindrical outer surface 1600 of the spool 1232 to some length.
The length of the slot may vary depending on the type or size of
the drive spring 1236 that is used for the particular winder
embodiment.
[0292] Referring now to FIGS. 16A and 16E, the front surface 1604
includes a front edge 1636. In at least one embodiment, the front
edge 1636 includes a second set of holes 1640 and teeth 1644. The
second set of holes 1640 are adapted to receive a plurality of
projections 1716 positioned on the front spool side 1228 (discussed

the front edge 1636 to selectively and/or removably engage and
interconnect the front surface 1604 of the spool 1232 to the first
face 1700 of the front spool side 1228.
[0293] In at least one embodiment, the teeth 1644 project radially
inward (i.e., toward the center of the spool) and are sized and
shaped to engage at least a portion of the pawl 1240. The teeth
1644 are oriented at an angle .alpha. in order to reduce and/or
prevent winder spin-out. Accidental spin-out is undesirable because
the user has to manually re-load the drive spring 1236 before the
cord/cable may be wound. As such, the engagement between the spool
1232 and the pawl 1240 is configured such that the drive spring
1236 is maintained in a loaded condition until the user is ready to
winder the cord/cable (thereby unloading the drive spring). In
order to achieve the desirable spool/pawl engagement, the teeth
1644 are properly angled to engage and maintain the engagement
(i.e., minimize slip) with the pawl teeth 1916. In at least one
embodiment, this engagement is achieved by orienting the teeth 1644
at an angle .alpha. that ranges from about 25 degrees to about 45
degrees. In a preferred embodiment, the teeth are oriented at an
angle .alpha. of about 37 degrees.
[0294] Referring now to FIGS. 16C and 16D, the outer surface 1600
of the spool includes grasping members. In at least one embodiment,
the grasping members are hooks 1648 adapted to selectively engage a

winding device 1200. One of skill in the art will appreciate that
the number of hooks 1648 positioned on the outer surface 1600 of
the spool 1232 may vary depending on a number of variables, such as
size, and the graspability of the object. For example, in at least
one embodiment, four hooks are provided. In another embodiment, two
hooks are provided. In yet another embodiment, seven hooks are
provided. One of skill in the art will appreciate that the grasping
members may include a variety of configurations. The grasping
element may take on a variety of different forms and is not limited
to a hook. By way of example and not limitation, a V-shaped
engaging mechanism that uses friction to hold the cord/cable and
allows the winder to pull the cord/cable into its frame may be
used. In at least another embodiment, a cord engaging mechanism
includes texturing for a plurality of superficial features to
assist with grabbing and holding the cord/cable. The height H of
the spool 1232 may vary depending on the exact configuration of the
grasping members.
[0295] In at least one embodiment, the spool 1232 is manufactured
as an integral piece using conventional injection molding processes
and is made from polyoxymethylene plastic (commonly sold under the
trade name "Delrin"). In other embodiments, the grasping members
may be individually and selectively interconnected to the outer
surface 1600 of the spool 1232, depending on the application. In
another embodiment, the teeth 1644 may be selectively removable
from the front surface 1604 such that they may be easily replaced
if they get worn or otherwise damaged.
[0296] A spool side of one embodiment is shown in FIGS. 17A-17E. In
at least one embodiment, the winder device includes two spool
sides, adapted for positioning on either side of the spool. One of
skill in the art will appreciate that in at least one embodiment,
the winder device has no spool sides, and in other embodiments, the
winder device has only one spool side, and in still other
embodiments, the spool sides are formed integrally with the
spool.
[0297] In at least one embodiment, the winder device 1200 includes
a front spool side 1228 and a back spool side 1224. The front and
back spool sides 1228 and 1224 are adapted to interconnect with the
spool 1232. In one embodiment, the front and back spool sides 1228
and 1224 are shaped as a substantially flat or planar torus
(doughnut-shaped) and have a first face 1700, a second face 1704,
an outer diameter 1708, and an inner diameter 1712. In at least one
embodiment, the second face 1704 of the back spool side 1224 is
adapted to abut a front surface 1400 of the back housing 1212 and
the second face 1704 of the front spool side 1228 is adapted to

inner diameter 1712. One of skill in the art will appreciate that
the plurality of projections 1716 may be spaced equidistantly,
non-equidistantly, or other configuration, around the perimeter of
the inner diameter 1712. In at least one embodiment, the plurality
of projections 1716 have a dowel pin or cylindrical rod shape. The
plurality of projections 1716 are adapted to be received by
corresponding fastening means, i.e., in corresponding holes on the
front and back surfaces 1604 and 1608 of the spool 1232. One of
skill in the art will appreciate that the plurality of projections
1716 may have various shapes and/or geometry, so long as the spool
1232 has corresponding or mating fastening means. One of skill in
the art will appreciate that any number of fastening mechanisms,
including screws, rivets, retaining rings, snap fits, or glues and
other adhesives, can be used to interconnect the front and back
spool sides 1228 and 1224 to the spool 1232.
[0299] In at least one embodiment, the front and back spool sides
1228 and 1224 are substantially identical parts. One of skill in
the art will appreciate that using front and back spool sides 1228
and 1224 that are substantially identical decreases the number of
different component parts that need to be manufactured and
increases the throughput of manufactured parts. However, one of
skill in the art can also appreciate that in some embodiments, it
may be desirable to have front and back spool sides that are not
substantially identical parts. For example, in other embodiments,
the front and back spool sides 1228 and 1224 have different
fastening mechanisms, are made from different materials, or have
different dimensions. In another embodiment, the front and back
spool sides 1228 and 1224 are integrally formed with the spool. In
still other embodiments, the winder device only includes one spool
side.
[0300] In at least one embodiment, the spool side(s) are made from
Delrin. One of skill in the art will appreciate that the spool side
may be made from any number of thermoplastics having high

bottom brackets 2320 and 2324 are integrally formed with the front
cover plate 1208. For example, in at least one embodiment, the
front cover plate 1208 includes integral top and bottom brackets
2320 and 2324. The top and bottom brackets 2320 and 2324 are
adapted to fasten the front cover plate 1208 to the front housing
1216. In at least one embodiment, the top and bottom brackets 2320
and 2324 mechanically interconnect to the front housing 1216 by a
snap fit. The top and bottom brackets 2320 and 2324 may include a
raised lip 2328 to enhance the snap fit design. One of skill in the
art will appreciate that any number of fasteners may be used to
interconnect the front cover plate 1208 and the back housing 1212,
such as a screws, rivets, pins, retaining rings, clamps, threaded
fasteners, or glues and other adhesives.
[0320] In at least one embodiment, the back surface 2304 of the
front cover plate 1208 further includes a surface treatment or
material, such as a non-slip, grippable, or traction providing
treatment (not shown) that facilitate a user's handling and
manipulation of the winder device 1200. Similarly, depending on the
application, it is envisioned that the front surface 2300 of the
front cover plate 1208 includes shock absorbing, drop resistant, or
other impact resistant material (not shown) to further protect the
winder device 1200 from damage. It is further envisioned, that the
front cover plate 1208 include decals or other ornamental features
to enhance the marketability of the winder device 1200.
[0321] It is to be understood that the cord winding devices
described herein may be used for a variety of cords and cables for
a variety of purposes and industries. Storing headphone cords and
kitchen appliance cables are but a few possible applications for
utilizing the winder device. Moreover, as one of skill in the art
can appreciate that the dimensions of the winder device may be
sized up or down depending on the application and the type of
cord/cable used.
[0322] Referring now to FIGS. 24A-24F, a spool 2400 of another
embodiment is shown. This spool configuration may be particularly
desirable and useful for larger winder applications that require a
larger spool. Should the particular application or use dictate that
the winder device have a larger size (i.e., to accommodate larger
cables/cords having a larger radius of curvature), instead of
re-sizing and manufacturing all of the component parts for the
winder, the spool 2400 may be re-configured to work with a smaller
pawl. Unlike the spool's discussed above, the front surface 2404 of
the spool 2400 includes a first face 2408 having a first diameter
D1 and a second face 2412, having a second diameter D2. In this
configuration, the grasping members are interconnected to the
second face 2412. Like the spools discussed above, the first face
2408 has teeth 2416 to operably engage the pawl teeth. Because the
teeth 2416 are positioned on the first face 2408, the dimensions of
the pawl and pawl teeth do not need to be increased, rather the
overall size of the spool 2400 may be increased simply by having a
second face 2412 with a larger diameter D2. The structural
stability and/or strength of the spool 2400 may be increased by
further including a plurality of radially extending struts (not
shown) that interconnect the first and second faces 2408 and 2412.
The second face 2412 may be slotted 2420 to receive mating
projections 2500 positioned on the spool sides 2500. FIGS. 25A-25E
show the spool side(s) adapted for use with the spool 2400. The
projections 2504 are sized to selectively interconnect to the
second face 2412 of the spool 2400.
[0323] Referring now to FIGS. 26A-26E a spool 2600 of another
embodiment is shown. This spool configuration may be desirable when
a low-profile or recessed spool would be useful for the particular
winder application. In this embodiment, the grasping members 2604
are integrated into the spool's outer periphery 2608.
[0324] In still other embodiment of the present inventions, the
winder device is configured to mate with an existing device, such
as a portable DVD player, an MP3 player, a smartphone, or other
commercially popular devices. FIGS. 27A-27D illustrate an exemplary
embodiment of a winder device 2700 adapted to work with an APPLE
brand IPHONE or IPOD. One of skill in the art will appreciate
IPHONE/IPOD users typically carry headphones or earbuds with them
so that they may watch television, movies, and to listen to music.
The winder device 2700 provides a way to safely store and protect
the associated earbuds/headphones unobtrusively.
[0325] One of skill in the art will appreciate that the structure
shown in FIGS. 27A-27D is consistent with the embodiments
previously described in detail herein. That is, similar in
structure to the embodiments discussed herein, the winder device
2700 generally includes back and front housings 2704 and 2708, back
and front spool sides 2712 and 2716, a spool 2720, a drive spring
(not shown), a pawl 2728, a button 2732, and button spring (not
shown). The winder device 2700 may also include a spacer 2740. In
at least one embodiment, the spacer 2740 includes an aperture 2744
and the front surface 2748 also includes a projection 2752. The
aperture 2744 and the projection 2752 are adapted to interconnect
with the pawl 2728. The front housing 2708 of the winder device
2700 may also include an aperture 2756 that is configured to allow
at least a portion of an axle 2760 to pass therethrough. One of
skill in the art will readily recognize the desirability and
advantages to storing earphones/earbuds and the desired device
(e.g., smartphone) together in a protective housing.
[0326] With reference now to FIGS. 28A-C and 29, in at least one
embodiment a winder device includes a biased member, such as a
mainspring or flat coil spring, in a biased condition. A means for
grasping an interior region of a folded or overlapped cord, such as
a hook (as shown in FIG. 29), is operatively associated with the
mainspring. Accordingly, the cord can be overlapped and engaged
with the hook (see FIGS. 28A and 29). Thereafter, a spring release
trigger, such as button, is depressed (as shown in FIG. 28B),
thereby causing the cord to be pulled into the winder device and to
be wound around an inner spool. Both portions of the cord are
adjacent each other and enter the same aperture, thereby allowing
the cord plugs to reside adjacent one another (as shown in FIG.
28C). Alternatively, the fold in the cord can be located closer to
one end than the other, and then the fold can be engaged with the
hook. Advantageously, in such a configuration cord plugs can be
established at different distances from the winder.
[0327] As those skilled in the art will appreciate, in at least one
embodiment the winder device is separate from the cord.
Accordingly, the winder device may be sold in a separate package.
The consumer then uses the winder device with any given cord to
wind the cord into the winder device. By way of example, a user
could purchase the winder device for use with stereo speaker
wiring, and thereafter engage a folded portion of the speaker wire
into the winder device to wind excess portions of the speaker
wire.
[0328] With reference now to FIG. 30, the cord grasping element may
take on a variety of different forms, and are not limited to a
hook. By way of example and not limitation, the V-shaped cord
engaging mechanism of FIG. 30 uses friction to hold the cord and
allow the winder device to pull the cord into its frame. In at
least one embodiment, a cord engaging mechanism includes texturing
or a plurality of surficial features to assist with grabbing the
cord.
[0329] With reference now to FIG. 31, a plurality of winder devices
are shown in a stacked configuration. In accordance with at least
one embodiment, the winder frames include a tongue and groove
structure and/or other engaging mechanism for allowing the winder
frames to be stacked. The winder frames may further include a
releasable lock structure, such as a biased catch that allows a
first winder to releasably interlock with a second winder.
[0330] In accordance with one or more embodiments of the present
invention, a winder device uses a ratchet and pawl system for
releasably securing the spring from unwinding. As shown in FIG.
28B, a button can be depressed that releases the spring and
retracts the cord. In at least one embodiment the button is located
near the center of one side of the winder. In an alternative
embodiment, the winder utilizes a squeeze release, wherein the
spring releases when the two halves of the winder are squeezed
together. In another embodiment, a cam or other lock-and-release
mechanism will be positioned on the outer perimeter of the
spool.
[0331] Embodiments of the winder device described herein may be
used in connection with a wide variety of electrically operated
devices. FIGS. 32A and 32B show a winder device in accordance with
at least some of the embodiments described herein used in
connection with a coffee maker. FIG. 33 shows a winder device in
accordance with the embodiments described herein used in connection
with a blow dryer. FIG. 34 shows a winder device in accordance with
the embodiments described herein used in connection with a
handheld/mobile device. FIG. 35 shows a winder device in accordance
with the embodiments described herein used in connection with a
lamp. As can be seen in FIG. 35, the two portions of the cord can
be different distance relative to the lamp. That is, the distance
between the socket and the winder is a different distance than the
distance between the winder and the lamp.
[0332] The present invention may be embodied in other specific
forms without departing from its spirit or essential
characteristics. The described embodiments are to be considered in
all respects only as illustrative and not restrictive. The scope of
