- kitchen appliances such as toasters, coffee makers, and blenders all have a power cable for the transmission of electrical power.
- audio-visual devices have a cord or cable.
- users use headphones or earbuds with their MP3 players and smart phones.
- the cost to replace damaged or broken cords/cables/headphones is increasingly expensive.
- 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.
- 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.
- winders of various size and characteristics are provided to wind and store a variety of cords or cables and to operate “automatically.”
- “automatically” means the winder device in its ready state can operate without turning a crank or handle in order to rotate a winding spool.
- a folded portion of a cable or cord is engaged around a grasping member, such as a hook.
- 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.
- the two ends of the cord/cable reach the entry point, the refraction stops.
- a winder device substantially as herein shown and described is provided.
- a device for winding a cord is provided.
- the cord is bendable to form a looped portion.

- a spool including:
- a pawl that is selectively moveable from a first position to a second position, the pawl including:
- the drive spring at least partially unloads and causes the spool to rotate in a winding direction, which causes the cord to wind onto the spool.
- the cord is wound onto the spool until at least one of three events occurs: (1) the cord is fully wound onto the spool; (2) the cord is pulled again to cause the plurality of pawl teeth to reengage the plurality of spool teeth; or (3) the spring release mechanism is deactivated.
- the plurality of spool teeth are oriented at an angle of about 25 degrees to about 45 degrees with respect to a vertical axis.
- the device for winding a cord further comprises at least one of a front spool side and a back spool side adapted to connect to a portion of the spool.
- the drive spring is a coil spring adapted to provide at least about 0.5 inch-pounds of torque.
- the spring release mechanism is a button.
- the front housing and back housing are interconnected by at least one of a strut, a pin, a screw, a rivet, a clamp, and a threaded fastener.
- an assembly comprising:
- a winder for winding the cord including:
- the means for biasing at least partially unloads and causes the means for rotating to rotate in a winding direction, the cord is wound onto the means for rotating until at least one of three events occurs: (1) the cord is fully wound onto the means for rotating; (2) the cord is pulled again; or (3) the bias release mechanism is deactivated.
- the assembly further includes extracting a desired length of the cord from the winder by exerting a force on the looped portion of the cord such that as the means for rotation rotates the means for preventing rotation slidably engages the means for slidably engaging in a ratchet configuration, and wherein the cord extraction re-loads the means for biasing.
- the means for preventing rotation are spool teeth oriented at an angle of about 25 degrees to about 45 degrees with respect to a vertical axis.
- the means for biasing is a coil spring.
- a winder for winding a cord is provided.

- a biased member connected to the spool, the pawl having at least a first position and a second position operably associated therewith;
- the biased member when in the second position, is at least partially unloaded by activating a spring release mechanism and releasing the cord, which causes the spool to rotate, which causes the cord to wind onto the spool.
- the biased member is a coil spring adapted to provide at least about 0.5 inch-pounds of torque.
- a method for selectively winding a cord comprising: folding the cord; operably engaging a portion of the folded cord with a grasping member of a winder; pulling on the cord to cause at least one pawl tooth of a pawl of the winder to disengage from at least one spool tooth of a spool of the winder; and activating a spring release mechanism operably associated with the pawl to at least partially unload a spring of the winder such that the spool rotates to wind the folded cord around the spool.
- the method further comprises deactivating the spring release mechanism to stop further spool rotation and spring unloading.
- the folded cord when the folded cord is fully wound around the spool, two end portions of the folded cord are collocated and substantially adjacent.
- the method further comprises extracting the cord from the winder to a desired length by pulling the folded cord such that as the spool rotates and the cord extraction re-loads the spring. In at least one embodiment, the method further comprises removing the cord entirely from the winder, wherein, when the cord is entirely removed, the spring remains in a loaded state.
- the grasping member is at least one of a hook and a v-shaped, friction engaging member.
- the spring release mechanism is activated by moving a button from a first position to a second position.
- the button cannot move from the first position to the second position unless the cord has operably engaged a grasping member, and, substantially simultaneously, a tension on the cord is exerted in a direction opposite from a winding direction and activating the button, and thereby preventing accidental spin-out.
- a device comprising:
- a frame having a cord access aperture for receiving the cord, the frame including an inner spool and a concentrically located spring operatively connected to a catch mechanism for engaging the cord; wherein the spring is adapted for winding the cord around the inner spool upon engaging the cord with the catch mechanism and releasing a brake operatively securing a tension in the spring.

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.
- 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.
- 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.
- FIG. 11C shows how the cable/cord 1100 is wound into the winder device 100 .
- 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 .
- 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 .
- 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.
- 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.
- 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.
- 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.
- the winder device 1200 includes front and back cover plates.
- 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.
- 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 .
- 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.

Abstract
A device for winding, storing, tangle prevention, and protecting cords and/or cables is described. The device for winding a cord includes a frame having a cord access aperture for receiving the cord. The frame also includes an inner spool and a concentrically located spring, such as a flat coil spring, operatively connected to a catch mechanism for engaging the cord. The spring is adapted for winding the cord around the inner spool upon engaging the cord with the catch mechanism and releasing a spring control, such as a ratchet and pawl, that serves to secure tension in the spring. Methods associated with such a device are also described herein.
Description
- 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.
- The present invention is related to a device for easily and unobtrusively winding, storing, and protecting cords and/or cables.
- 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.
- 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.
- 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.

FIGS. 9A-9H , thebutton 132 of at least one embodiment is shown. Thebutton 132 generally includes afront face 900 and aback face 904 and is adapted to interconnect to thebutton plate 140 and thefront housing 108. - In at least one embodiment, the
back face 904 of thebutton 132 abuts at least a portion of thebutton receiver 736 on thefront housing 108.Brackets 908 may be used to at least partially retain thebutton 132 within thebutton receiver 736. In at least one embodiment, thebutton 132 has twobrackets 908, one on either side of theback face 904 of thebutton 132, that are adapted to be received in thebracket receiving slots 812 of thebutton plate 140. As such, thebutton 132 is slidably engaged with thebutton plate 140 and thebutton 132 is able to move within thebutton receiver 736. - The
back face 904 of thebutton 132 is also generally adapted to engage at least a portion of thepawl 128. In at least one embodiment, theback face 904 includes apawl receiver 912. Thepawl receiver 912 may be shaped to correspond to the shape of the pawl'sprojection 624. In at least one embodiment, thepawl receiver 912 is substantially D-shaped (to interconnect to a D-shapedprojection 624 on the pawl 128). In other embodiments, thepawl receiver 912 is substantially O-shaped, polygonally shaped, or conically shaped to receive a corresponding pawl projection. - In at least one embodiment, the
back face 904 of thebutton 132 also includes aspring receiver 916 configured as a longitudinal slot. Thespring receiver 916 is adapted for receiving theclip 740 on thefront surface 700 of thefront housing 108. Thespring receiver 916 is also adapted to receive a biased member. An exemplary biased member is illustrated inFIGS. 10A-10C . In at least one embodiment, the biased member is a coil orhelical button spring 1000. Thebutton spring 1000 may be made from a number of materials. Thebutton spring 1000 is adapted for positioning within thespring receiver 916. As such, theclip 740 is proximate thebutton spring 1000. Thebutton spring 1000 of at least one embodiment is adapted to store and release a sufficient amount of energy such that when thebutton 132 is moved from a first position of use to a second position of use, thebutton spring 1000 is loaded (i.e., compressed against the clip 740) and when thebutton 132 is moved from the second position of use to the first position of use, thebutton spring 1000 is unloaded (i.e., expands away from the clip 740). - The
front face 900 of thebutton 132 may include surface features to assist a user's manipulation of thebutton 132. For example, in at least one embodiment, thefront face 900 has a grippable or textured surface (not shown) such that users of varying age and dexterity may slidably move thebutton 132. - Although an
exemplary winder device 100 is depicted inFIGS. 1A-10C , one of skill in the art can appreciate thewinder 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. - Referring now to
FIGS. 11A-11C , the operation of at least one embodiment of thewinder 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) thewinder device 100, thespool 120 rotates. When thespool 120 rotates, thespool 120 engages thepawl 128 and torque is transmitted to thedrive spring 124. As such, the rotation of thespool 120 causes thedrive spring 124 to wind/spiral tighter, which loads thedrive spring 124. In the loaded condition, thedrive spring 124 stores a certain amount of energy. Moreover, as thespool 120 rotates, theteeth 344 on thespool 120 selectively engage thepawl teeth 616 such that when the user stops pulling on the cord/cable 1100, thepawl teeth 616 lock the position of thespool 120 in place. Because of the engagement between thepawl teeth 616 and spool'steeth 344, thespool 120 is held in place and is maintained in a loaded state, which prevents thedrive spring 124 from releasing its energy. -
FIG. 11C shows how the cable/cord 1100 is wound into thewinder device 100. When the user is ready to wind the cable/cord 1100 onto thespool 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 thepawl teeth 616 from thespool 120. Once thepawl teeth 616 have disengaged, the user is able to move thebutton 132 from a first position of use to a second position of use (by moving the button up in the embodiment shown), which moves thepawl teeth 616 away from the spool'steeth 344. Once thepawl 128 and thespool 120 are disengaged, thedrive spring 124 is able to release and return to an unloaded state. Unloading thedrive spring 124 causes thespool 120 to spin and wind the cable/cord 1100 into thewinder 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. - 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.

FIGS. 12-23 , another embodiment of the present inventions is illustrated. To draw a few exemplary and non-limiting distinctions between thewinder device 100 of at least one embodiment (discussed above) and thewinder device 1200 of at least another embodiment (discussed below), one will notice that in the embodiment shown inFIGS. 12-23 , thewinder 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, thewinder device 100 without cover plates may be advantageous. Alternatively, when a more robust winder is desired, thewinder device 1200 having cover plates may be advantageous. To further contrast the at least two embodiments, thewinder device 100 has anaxle 232 that is integral to theback housing 104 whereas thewinder device 1200 has anaxle 1220 separate from theback cover plate 1204 and backhousing 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. - Referring now to
