Full 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.

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&#39;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 α 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 α that ranges from about 25 degrees to about 45 degrees. In a preferred embodiment, the teeth  344  are oriented at an angle α 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&#39;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  7 G- 7 H, 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&#39;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&#39;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&#39;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&#39;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&#39;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&#39;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).

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).

         [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 below). Any number of interconnecting mechanisms may be included on 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 α 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 α that ranges from about 25 degrees to about 45 degrees. In a preferred embodiment, the teeth are oriented at an angle α 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 portion of a cord, cable, or other object to be used with the 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.

         [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 abut a back surface  2004  of the front housing  1216 . 
         [0298]    In addition, in at least one embodiment, a plurality of projections  1716  positioned on the first face  1700  of the front and back spool sides  1228  and  1224  are positioned proximate to the 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.

In some embodiments, when the button  1244  is aligned in the window  2308  of the front cover plate  1208 , the button  1244  is substantially flush with the front surface  2300  of the front cover plate  1208 . In other embodiments, the button  1244  extends beyond the front surface  2300  of the front cover plate  1208 . 
         [0319]    The front cover plate  1208  also includes top and bottom brackets  2320  and  2324 . In at least one embodiment, the top and 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&#39;s handling and manipulation of the winder device  1200 .

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&#39;s discussed above, the front surface  2404  of the spool  2400  includes a first face  2408  having a first diameter D 1  and a second face  2412 , having a second diameter D 2 . 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 D 2 . 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&#39;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.
