DETAILED DESCRIPTION OF THE INVENTION
(24) Reference will now be made in detail to the description of the present subject matter, one or more examples of which are shown in figures. Each embodiment is provided to explain the subject matter and not a limitation. These embodiments are described in sufficient detail to enable a person skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that logical, physical, and other changes may be made within the scope of the embodiments. The following detailed description is, therefore, not be taken as limiting the scope of the invention, but instead the invention is to be defined by the appended claims.
(25) The present invention provides a detachable spring loaded headphone reel for storing and protecting the headphone cable against tangle, misfire and slip off. The headphone reel comprises a base plate, a spindle, at-least two cover plates, a lever and a spring. The spring provides enforcing mechanism during the rotation of the spindle in clockwise and counter clockwise direction. The spindle rotation allows the head-phone cable to wrap and store around the dial for a sufficient number of revolutions to coil up the cable. In one embodiment, the spindle rotation is capable of between about 5 to 7 complete revolutions. The ear buds of the headphone may be placed in the slips of the cover plates once the headphone cable is stored in the dial of the spindle.
(26) In a preferred embodiment, the headphone reel (100) comprises a base plate (101), a spindle (108), at least two cover plates (112), a pawl-type lever (116) and a spring (119). The base plate (101) includes a wall (102). The base (101) further includes a ring wall (103) with an opening (103a), two flanges (104a and 104b), a release arch (105), release slot (106), a pivot nub (120) centered on axis (10) on the base underside (101b) for securing one end (119a) of spring (119) to the base (101), and an anchor bay (107). The two flanges are the first flange (104a) and the second flange (104b). The two flanges (104a and 104b) are extended from the wall (102) and placed on opposed sides of the wall (102). The release arch (105) is attached to the first flange (104a).
(27)
(28) In a preferred embodiment, the headphone reel (100) comprises a base plate (101) having outer surface (101a) and inner surface (101b). The reel device (100) further comprises a spring wound spindle (108), rotatable about an axis (10), further including a ratchet gear (111) capable of engaging with a pawl lever (116), at least two cover plates (112), and a tensioning spring (119).
(29)
(30)
(31)
(32) In a preferred embodiment, the spindle (108) comprises a disc (109) with an upper end (109a), a lower end (109b) and an outer circumferential edge (1090. The upper end (109a) further comprises a generally cylindrical dial (110) disposed a distance inwardly about the axis (10) from the outer circumferential edge (1090 and extending upwardly a distance from the disc upper end (109a) surface. The dial (110) further comprises outer circumferential surfaces (110d) for receiving the spooled headphone cable (20a).
(33) The dial (110) further comprises a dial shelf or shoulder (110c) at its top outer circumference leaving the remaining upper portion of the dial to form lip shaped surfaces (110e) that extend upwardly. As will be seen in connection with the other figures, the plate covers (112) attach to the base flanges (104a, 104b) and have as one function, the creation of a semi-enclosed internal space (30) to permit housing of the coiled or spooled cable (20a). Another function of the cover plates is to provide an upper boundary to retain the spindle, such that, as the spindle moves about the axis (30), the spindle will have some room to move upward, but the covers (112a, 112b) will retain the spool (108) within the reel device (100) via interaction with the dial shoulder or shelf (110c). The opposed plate covers do not extend around the entire circumference of the spindle (108) so as to permit top loading of the cable (20a) into the slots. Once the cable is loaded into the slots, the headphone cable (20a) is wound around the dial and stored within semi-enclosed space (30).
(34) The lower end of the disc (109) includes a ratchet gear (111) comprising a plurality of cog or ratchet teeth (111a) disposed about the circumference of the gear (111), the gear (111) being attached to the underside (109b) of the spindle (108), and extending downwardly, the gear also being disposed inwardly from the disc outer circumferential edge (109f) to permit the ratchet gear outer circumference to fit within the ratchet gear receiving area (103b) within the ring wall (103). The lower end (109b) having the cog teeth (111a) is positioned inside the ring (103) thereby creating a gap between the base plate ring wall (103) and the cog teeth (111a) to achieve better stabilization during rotational and translational movement therein. The ratchet gear (111) is a generally hollow cylindrical shape extending downwardly from the spindle underside (109b), the gear teeth (111a) being located on the outer surface of the cylinder. The inner surface (109g) of the gear cylinder forms the housing area (109e) for the spring 119. The inner gear cylinder surface (109g) further comprises a spring catch (109c) extending therefrom forming a spring catch groove (109d) for receiving one end (119b) of the spring (119). The other end (119a) of the spring attaches within the pivot nub slot (120a) of the pivot nub (120) located at the axial (10) midpoint on the base underside (101b).
(35)
(36)
(37)
(38) The two cover plates (112) include top portions (112a and 112b) and bottom portions (118a, 118b). The cover plates (112) comprise primary sides (114a and 114b) and secondary sides (113a and 113b). The bottom portion (118a) of the secondary side (113a) and the bottom portion (118b) of the secondary side (113b) of the cover plates (112) are extended with flanges (115a and 115b). The flanges (115a and 115b) of the two cover plates (112) and the flanges (104a and 104b) of the base plate (101) are conjoined together to achieve better stabilization between the two cover plates (112) and base plate (101) during winding or pulling operation of the headphone cable (20a).
(39) The primary sides (114a, 114b) of the cover plates (112) provide an appropriate horizontal stabilizing force to the lip shaped surfaces (110e) at the top of slots (110a and 110b). The bottom portions (118a, 118b) of the cover plates (112) provide lateral stabilizing force and retaining force to the dial shelf or shoulder (110c) of the spindle (108) in spindle retaining area (118c) during its operation by retaining the upward movement of the dial shelf (110c) within the spindle retention gap (118d). The cover plates (112) serve to prevent the headphone cable (20a) from slipping off of the dial (110) of the spindle (108).
(40) Referring to
(41) In a preferred embodiment, the pawl lever (116) includes a first pivot end (116a) and a second end (116b) that a user can press, e.g., with the user's thumb or finger. The second end (116b) may comprise a smooth surface, or a surface comprising surface features, such as ridges or grooves (as shown) or other gripping material. The pawl first end (116a) is at placed at the anchor bay (107) and the pawl second end (116b) is allowed to protrude towards the release slot (106) of the base plate (101). The second end (116b) of the pawl lever (116) is engaged or pressed when the user(s) desires to wind the head-phone cable around the dial (110d) of the spindle (108). The pawl lever (116) also comprises a pawl engagement point (116c) for engaging with or disengaging from the ratchet gear (111) and a flex point (116d) to permit the inward and outward movement of the engagement point (116d).
(42) Referring now to
(43)
(44)
(45)
(46) As thus constructed, cable (20a) is subjected to a continuous tension by spring (119). A ratchet and pawl mechanism in permits cable (20a) to be withdrawn to a desired length and go slack. Ratchet gear (111) is fixably attached to spindle (108). The periphery of gear (111) is serrated or toothed for engaging a pawl as illustrated in
(47) The ratchet and pawl mechanism, coupled with the action of spring provides a one-way restriction on the motion of cable (20a), enabling cable (20a) to be withdrawn from base (101) but preventing cable (20a) from being retracted into base except upon manual disengagement of the pawl engagement point from the ratchet gear by pressing on the pawl engagement end (116b). Other mechanisms for controlling cable (20a) could be used instead, such as a cam or friction brake engaging cable (20a).
