Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cord-like body winding device and a manufacturing method thereof, and in particular, a winding device that winds an excess portion of a cord-like body such as a cord in which a signal line is arranged and an outer peripheral side is covered with insulation. Regarding the method.

  With the advancement of mobile phone technology, various functions can be attached. That is, not only functions such as digital cameras and music players, but also functions as a television broadcast receiver called one-segment television, payment such as Suica (registered trademark), Felica (registered trademark), etc. Various additional functions such as functions tend to be added. This allows the music player to be hung from the neck with a neck strap, placed in a chest pocket or bag, and used as a mobile phone instead of acting with a wallet or commuter pass. It can be hung from the neck with a neck strap to watch television broadcasts, move by train, or shop.

  On the other hand, it is possible to provide a winding device for winding a cord in an electronic device with a cord for transmitting a power source or an audio signal, for example, Japanese Patent Publication No. 5-34840 or Japanese Utility Model Publication No. 57-91389. As disclosed in the Gazette, it has been widely performed conventionally. Even in headphones and headsets, the use of a winding mechanism for winding a cord for the purpose of preventing the cord from being entangled at the time of storage is not uncommon. Under such circumstances, more convenient portable performance is considered by the development of portable electronic devices such as a portable digital player that reproduces hundreds or thousands of songs and videos, etc. There is a tendency to require the use method.

  However, there are no convenient strap-type headphones or headsets for mobile phones that are especially multifunctional. This is because when a conventional small player is of a type that is suspended from the neck by a neck strap, and a mobile phone having a one-segment television receiver function or a settlement function is suspended from the neck. The hanging length from the neck strap to the mobile phone is a constant value from the neck to the chest. Therefore, if an attempt is made to watch a television receiver using the one-segment function with a mobile phone in the state as it is, the distance from the chest becomes a value of about 20 cm, and the position of the display becomes too close. For this reason, it is necessary to remove the neck strap when viewing the television receiver with a mobile phone. The automatic ticket gate also has an automatic ticket gate touch sensor at a waist level, so it is unnatural to hold a mobile phone suspended from the neck by a neck strap over the automatic ticket gate touch sensor. Therefore, it was necessary to remove the cellular phone from the neck and access the cellular phone to the touch sensor of the automatic ticket gate.

Further, the total length of the cord wound by the winding device is determined assuming the maximum drawing length. In practice, however, the length of the code used varies depending on the mode of use, the user's preference, and the like. Thus, when set to the maximum length, the code will cause more or less excess. Accordingly, unless such surplus portion is wound by any winding means, there is a problem that the cord is caught on another part or the handling becomes troublesome.
Japanese Patent Publication No. 5-34840 Japanese Utility Model Publication No. 57-91389

  The subject of this invention is providing the winding apparatus of the string-like body which can wind up an excess string-like body arbitrarily.

It is related with a string-like body winding device provided with.

  Here, it may be integrally formed of an elastic material. Moreover, you may shape | mold integrally with rubber | gum. Moreover, the hook part which hooks the said string-like body may be provided in the said winding-up part. The flange portion is substantially cup-shaped, and the pair of flange portions take a back-to-back posture at the separated position, and the pair of flange portions face each other at a close position, and the flange portion is in the flange portion. You may make it the said winding-up part which wound up the string-like body located. The string-like body may be a cord.

The invention relating to the manufacturing method is such that a rod-like or cylindrical take-up portion that winds a string-like body around an outer peripheral portion and an axial end of the take-up portion that are integrally connected to each other. In a manufacturing method of a string-like body winding device comprising: a separation position that is separated in a direction; and a flange portion that is displaced between a separation position that faces each other and an outer peripheral edge portion abuts or approaches.
A pair of first molds that are in contact with the outer peripheral portion of the winding portion and the outer peripheral portion of the separated flange portion and are movable in a direction orthogonal to the axial direction of the winding portion, and the flange portion in the separated state And a pair of second molds that are movable in the axial direction of the winding portion, and are formed by the closed first mold and the second mold. The present invention relates to a method for manufacturing a string-like body winding device characterized by injecting and molding an elastic material into a cavity.

  The main invention of the present application is a rod-like or cylindrical take-up portion that winds a string-like body around an outer peripheral portion, and is integrally connected to both ends in the axial direction of the take-up portion. And a flange portion that is displaced between a separation position that separates in the direction and a proximity position that faces each other and the outer peripheral edge abuts or approaches.

  Therefore, according to such a cord-like body winding device, the cord-like body is wound around the winding portion in a state where the pair of flanges at both ends are separated from each other. The flange portion is displaced so as to exceed a predetermined position so as to be in a close position, whereby the winding portion around which the string-like body is wound is covered. Therefore, not only is winding easy, but it is possible to hold the wound string-like body in an invisible state, and the string-like body is held inside the flange. Unexpectedly unraveling from the winding part.

  The main invention related to the manufacturing method is that a rod-like or cylindrical take-up portion that winds a string-like body around the outer peripheral portion, and a single continuous connection at both ends in the axial direction of the take-up portion.

A pair of first molds that are in contact with the outer peripheral portion and the outer peripheral portion of the separated flange portion and are movable in a direction perpendicular to the axial direction of the winding portion, and are in contact with the inner side of the separated flange portion for winding And a pair of second molds movable in the axial direction of the part, and injecting an elastic material into a cavity formed by the closed first mold and the second mold It is what you do.

  Therefore, according to the manufacturing method of such a string-like body winding device, the pair of first and second molds are closed in the cavity formed between these molds. By injecting and molding the elastic member, the string-like body winding device can be integrally formed, and the string-like body winding device can be easily formed.

  The present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 shows the overall configuration of a hanging device for a mobile phone according to the present embodiment, and this hanging device includes a neck strap 10. The neck strap 10 is wound around the neck so as to suspend and hold the mobile phone 20. A cord 11 is routed along the length direction of the neck strap 10, and the cord 11 is separated from the neck strap 10 at the position of the presser 14. An earphone 12 or a headphone is connected to the tip of the cord 11. The earphone 12 functions as a playback device when the mobile phone 20 is used as a music player. Alternatively, the earphone 12 is used as a handset when the mobile phone 20 is used hands-free.

  A winding device 13 is attached to a portion of the neck strap 10 that hits the pendant. The connecting member 16 is connected to the cylindrical mouth portion 15 on the lower end side of the winding device 13, the cord 17 is pulled out from the side of the connecting member 16, and the plug 18 is connected to the distal end portion of the cord 17. ing. The plug 18 is inserted into a jack on the side of the mobile phone 20. The mobile phone 20 is suspended from the connecting member 16 via a suspension string 21.

  A feature of the hanging system of the cellular phone 20 is that the load of the cellular phone 20 is suspended by the neck strap 10 via the winding device 13, the connecting member 16, and the hanging strap 21. Here, the load of the cellular phone 20 is not applied to the cord 17 that can be drawn and wound by the winding device 13. This is because the coupling member 16 is provided with an engagement mechanism, and this engagement mechanism employs a structure in which the coupling member 16 is engaged and held with the cylindrical mouth portion 15 of the casing of the winding device 13. is there.

  When the engagement between the cylindrical mouth portion 15 of the winding device 13 and the connecting member 16 is released, the connecting member 16 is detached from the cylindrical mouth portion 15 as shown in FIG. Accordingly, when the cellular phone 20 is held by hand and moved away from the winding device 13, the cord 17 connected to the plug 18 connected to the cellular phone 20 is connected to the cylindrical port of the winding device 13. It is pulled out from the part 15. Therefore, the cellular phone 20 can be moved to an arbitrary position by arbitrarily pulling up to the maximum length of the cord 17 wound on the winding device 13. Therefore, for example, when accessing the touch sensor of the automatic ticket gate, the connecting member 16 can be detached from the cylindrical mouth portion 15 and the mobile phone 20 can be easily held over the touch sensor of the automatic ticket gate.

  FIG. 3 shows the configuration of the winding device 13 and the connecting member 16. The winding device 13 includes a chassis 25, and a support shaft 26 is provided so as to stand at the center of the chassis 25. A reel 27 for winding the cord 17 is rotatably supported by the support shaft 26. An upper portion of the reel 27 is a recess 28, and a mainspring 29 is accommodated in the recess 28. The mainspring spring 29 is charged with an elastic restoring force for winding the cord 17 on the outer peripheral surface of the reel 27. A slip ring is provided on the lower surface of the reel 27, and a brush 30 is attached to the bottom of the chassis 25 so as to come into contact with the slip ring. The brush 30 is connected to the cord 11 arranged along the neck strap 10. Therefore, the cord 17 that can be wound by the reel 27 and the cord 11 arranged along the neck strap 10 are electrically connected to each other by the slip ring and the brush 30.

  A front cover 35 is attached to the lower surface of the chassis 25. On the other hand, a rear cover 36 is attached to the upper side of the chassis 25. A support shaft 37 is erected on the lower surface of the rear cover 36, and a holder 38 is disposed on a side portion of the support shaft 37, and the ball 39 is supported by the holder 38. The ball 39 is formed of a steel ball and is fitted into the groove of the lock disc 40. Moreover, since the lock disc 40 is coupled to the reel 27, the cord 17 is pulled out and locked through the lock disc 40.

  A semi-cylindrical portion 43 extended from the chassis 25 and a semi-cylindrical portion 44 pressed by the rear cover 36 are mutually connected to the lower end portion of the winding device closed by the front cover 35 and the rear cover 36. The cylindrical mouth portion 15 is assembled by this. An engagement groove 45 is formed on the outer peripheral surface of the cylindrical mouth portion 15, and the engagement between the connecting member 16 and the winding device 13 is achieved by the engagement groove 45. A holding ring 46 is attached to the base side of the cylindrical mouth portion 15 in order to hold the semi-cylindrical portions 43 and 44 constituting the cylindrical mouth portion 15 in a coupled state. FIG. 5 shows a cross-sectional configuration of the winding device according to the above configuration.

  Next, the structure of the connecting member 16 that is connected to the cylindrical mouth portion 15 of the winding device 13 so as to be engageable and disengageable will be described. As shown in FIGS. 3 and 6, the connecting member 16 includes a cylindrical cord holder 51, and the cord 17 is inserted through the cord holder 51 and pulled out to the side. A rear-side presser 52 is attached to the upper portion of the cord holder 51, and an operation member 53 is attached to the lower end side. Further, on the inner side of the operation member 53, support shafts 54 project so as to face each other. The support shaft 54 is rotatably supported by a bearing 55 provided on the lower surface of the cord holder 51. That is, the operation member 53 is rotatably supported on the lower surface of the cord holder 51 through the support shaft 54 and the bearing 55. In addition, a winding spring 56 is attached around the support shaft 54, and the operation member 53 is urged to rotate counterclockwise about the support shaft 54 as shown in FIG. It is like that.

  A pair of hooks 57 are integrally formed on the inner surface of the operation member 53, and the clip spring 58 is supported by the hooks 57. The clip spring 58 has a substantially U-shape and is received in slits 59 formed on both sides of the cord holder 51, and the clip spring 58 is engaged with an engagement groove on the outer peripheral surface of the cylindrical mouth portion 15. By being engaged with 45, the connecting member 16 and the cylindrical mouth portion 15 of the winding device 13 are engaged with each other. Accordingly, the connecting member 16 can receive the load by the winding device 13 through the cylindrical mouth portion 15, and the cord 17 does not receive the load of the mobile phone 20.

  An attachment member 62 is attached to the end of the cord holder 51. The attachment member 62 is adapted to attach the hanging strap 21. The hanging strap 21 is inserted into the strap insertion hole of the mobile phone. Accordingly, the connecting member 16 suspends and supports the mobile phone 20 via the suspending strap 21 attached to the attachment member 62.

  Next, the structure of the plug 18 connected to the tip of the cord 17 that is the tip of the cord 17 and drawn from the side of the cord holder 51 will be described. As shown in FIGS. 3 and 6, the plug includes plug cases 67 and 68 joined to each other from both sides, and a circuit board 69 is disposed in the plug cases 67 and 68 as shown in FIG. Yes. A microphone 70 is mounted on the circuit board 69. An operation button 71 is attached to the upper part of the plug cases 67 and 68.

  Next, the operation of winding the cord 17 by the winding device 13 will be described. As shown in FIG. 4, the lock disc 42 has an outer peripheral groove 75 formed on the outer peripheral side thereof. A wall 76 is formed at a predetermined position in the circumferential direction of the outer circumferential groove 75. The wall 76 has a relatively low height. A V-shaped lock portion 77 is formed in the vicinity of the wall portion 76. Further, an inner circumferential groove 78 is formed on the center side of the lock disc 40. A communication groove 79 is formed so that the inner circumferential groove 78 and the outer circumferential groove 75 communicate with each other.

  In the winding mechanism portion of the cord 17 using the lock disc 40 as described above, when the cord 17 is pulled out, the reel 27 returns slightly and stops, and when winding, the winding starts when the cord 17 is pulled a little. The operation is performed. This operation will now be described with reference to FIGS. 4A, 4B and 4C. In this winding device, the winding disk 40 is coupled to the reel 27, while the ball 39 is moved in the radial direction by the holder 38. However, here, for convenience of explanation, in consideration of the fact that the ball 39 rotates relative to the lock disk 40, the description will be made with the ball 39 rotated with respect to the lock disk 40.

  The ball 39 moves clockwise on the groove 75 on the outer peripheral side of the lock disc 40 shown in FIG. 4A when the cord 17 is pulled out. Here, while the cord 17 is being pulled out, it is repeated to get over the wall portion 76 that blocks the groove 75 on the outer peripheral side, whereby the total length of the cord 17 wound on the reel 27 is reduced. Also makes it possible to unwind.

  When the drawing of the cord 17 is stopped, the reel 27 rotates counterclockwise by the elastic restoring force of the mainspring spring 29 as shown in FIG. 4B, and the cord 17 is wound around the reel 27. At this time, the ball 39 moves in the clockwise direction in the groove 75 on the outer peripheral side of the lock disc 40 and is hooked on the V-shaped lock portion 77 continuous with the inner groove 78. A locking operation is performed. That is, in such a state, the relative motion between the ball 39 and the lock disc 40 is stopped, and the reel 27 is locked. When the ball 39 is positioned at the maximum retracted position 80 in FIG. 4B, the ball 39 returns to the locked position counterclockwise along the longest path, and thereby the cord 17 of about 80 mm at the maximum is retracted. Will stop.

  When the cord 17 is further pulled while the ball 39 is locked to the V-shaped lock portion 77 as described above, the ball 39 moves from the V-shaped lock portion 77 through the inner circumferential groove 78 in the clockwise direction. The wall portion 81 that separates the V-shaped lock portion 77 from the inner circumferential groove 78 cannot be climbed when the ball 39 rotates counterclockwise, but this wall portion moves when the ball 39 moves clockwise. It is possible to get over 81. Thereafter, the ball that has passed through the inner circumferential groove 78 moves in the outer circumferential groove 75 by the communication groove 79, and for this purpose, the same operation as that shown in FIG. 4A is performed. If the cord 17 is returned while the ball 39 is in the inner circumferential groove 78, the ball 39 continues to rotate in the counterclockwise direction on the inner circumferential groove 78, so that the locking operation is not performed. 17 is rewound over its entire length. The lead length of the cord 17 is 0.5 m, and the maximum length that can be locked is 0.45 m.

  As the mainspring spring 29 disposed below the lock disc 40, a leaf spring having a leaf pressure of about 0.1 mm is used. In general, the mainspring spring 29 cannot bear the force required to suspend a mobile phone of about 160 g with a one-segment function and a settlement function. Accordingly, when the hand is released in a state where the lock by the lock disc 40 is released, the mobile phone 20 falls while the cord 17 is pulled out from the reel 27 of the winding device 13, but the operation of the reel 27 is performed at this time. Thus, the fall of the mobile phone 20 is buffered, so that a large impact is prevented from being applied to the mobile phone 20. Further, in order to perform winding, it is only necessary to pull the cord 17, and therefore a winding button is not required. By eliminating the winding button, it is possible to prevent inadvertent winding when the strap is attached.

  Next, the engagement and disengagement structure between the connecting member 16 and the cylindrical mouth portion 15 will be described with reference to FIG. When the connecting member 16 is connected to the cylindrical mouth portion 15 of the winding device 13, the cylindrical mouth portion 15 enters the central hole portion of the cord holder 51 as shown in FIG. 7A. Therefore, the clip spring 58 facing the slit 59 of the cord holder 51 gets over the tapered portion on the tip end side of the cylindrical mouth portion 15 and falls into the engagement groove 45. That is, the clip spring 58 achieves an engagement structure between the cylindrical mouth portion 15 and the connecting member 16. Therefore, the mobile phone 20 suspended from the connecting member 61 via the suspension strap 21 is in a state in which the load is borne by the casing of the winding device 13 due to the engagement structure of the clip spring 58 described above.

  Next, when the operating member 53 of the connecting member 16 is pressed as shown in FIG. 8 and the operating member 53 is rotated clockwise around the support shaft 54 against the winding spring 56, the operating member 53 is operated. The hook 57 on the back side of 53 pulls the clip spring 58 downward. As a result, the clip spring 58 facing the slit 59 is detached from the engagement groove 45 of the cylindrical mouth portion 15. As a result, the engagement between the cylindrical mouth portion 15 of the winding device 13 and the connecting member 16 is released.

  Therefore, for example, when watching a television broadcast with the mobile phone 20 using the one-segment function or when the mobile phone 20 is accessed by the touch sensor of the automatic ticket gate, as shown in FIG. Can be positioned greatly downward. At this time, the cord 17 having the plug 18 connected to the cellular phone 20 is drawn out from the cylindrical mouth portion 15 of the winding device 13. That is, when the mobile phone 20 passes the automatic ticket gate, the cylindrical mouth portion 15 is operated by operating the operation member 53 of the connecting member 16 to which the hanging strap 21 is attached while holding the mobile phone 20 with one hand. It becomes possible to remove the connecting member 16 from.

  Next, the winding device 85 for the cord 17 (see FIG. 1), which is pulled out from the side portion of the connecting member 16 and has the plug 18 connected to the distal end portion, will be described. As shown in FIGS. 9 to 11, the winding device 85 is a molded body that is integrally formed of an elastic material, for example, rubber, and is configured as a winding portion 86 in which an intermediate portion forms a rod shape. The winding portion 86 does not necessarily have to be a non-empty rod shape, and may be formed of a cylindrical body. A cup-shaped or hemispherical flange 87 is integrally connected to both sides of the winding portion 86. As shown in FIGS. 9A and 9B, the flange 87 is in a state where the flanges 87 on both sides are back-to-back with each other, and the outer peripheral edges of the flanges 87 on both sides are in contact with or close to each other as shown in FIG. 9C. By adopting a posture, and elastically deforming the flange 87, the posture of either the separation position or the proximity position is taken with a certain position as a boundary. Further, the winding portion 86 is formed with a hook portion 88 formed of a concave portion as shown in FIG. 10 at an intermediate position thereof, and a portion of the winding cord 17 is inserted and pulled by the hook portion 88. I try to hang it.

  Thus, when winding the cord 17 by the winding device 85 integrally formed of rubber, the cord 17 is hooked on the hook portion 88 of the winding portion 86 as shown in FIGS. 9A and 10. In such a state, the cord 17 is wound around the outer periphery of the winding portion 86 as shown in FIGS. 9B and 10. As shown in FIG. 1, the winding amount is set to a length for winding a surplus portion longer than the required length of the cord 17.

  When winding the cord 17 by the winding portion 86, as shown in FIGS. 9A, 9B, and 10, the cup-shaped flanges 87 on both sides of the winding portion 86 are elastic so that they are back to back with each other. Deform it. This facilitates winding of the cord 17 around the winding portion 86. When the winding is finished, the flanges 87 on both sides are elastically deformed so as to be in the proximity state as shown in FIGS. 9C and 11. In the deformation operation of the flange 87, the flange 87 is elastically deformed beyond a predetermined position so that the outer peripheral edge portions of the flange 87 are brought close to or in contact with each other. When changing to such a posture, as shown in FIG. 9C in particular, the winding device 85 has a substantially spherical shape as a whole, and the cord 17 wound by the winding portion 86 is hardly visible from the outside. Moreover, since the internal winding portion is covered with the flange 87, the cord 17 is not unwound unintentionally.

  A forming apparatus for forming such a winding device 85 is shown in FIG. That is, here, a pair of first molding dies 91 that can be opened and closed in the vertical direction perpendicular to the axial direction of the winding portion 86 and a second molding die 92 that can be opened and closed in the axial direction of the winding portion 86 are provided. I have. By closing these molds 91 and 92, the molten rubber is injected into a cavity formed between these molds and molded so that the winding device 85 is integrally molded. Become. Since such a winding device is a rubber injection-molded body as described above, it is integrated and has a structure in which the flange 87 can be elastically deformed. Further, the winding device 85 having a single number of parts is manufactured.

  As described above, in the present embodiment, in the headphone / head device of the strap device type in which the cord 17 connected to the mobile phone 20 is wound up by the reel 27 including the mainspring spring 29, the connecting member 16 having the clip spring 58 is provided. By using the mobile phone 20, even if the mobile phone 20 is heavy, the mobile phone 20 does not slide down regardless of the weight of the mobile phone 20, and when the mobile phone 20 is pulled out, it is light against the mainspring 29 having a weak elastic restoring force. The reel 27 can be pulled out, and the winding force of the reel 27 by the mainspring spring 29 is not too strong. Further, since the length of the cord 17 can be adjusted by connecting the cellular phone 20 to the cord 17 via the plug 18, when the television receiver is viewed by the cellular phone 20 using the one-segment function. The cellular phone 20 can be viewed while being lowered from the neck by the neck strap 10. Further, when accessing the touch sensor of the automatic ticket gate, as shown in FIG. 2, the cellular phone 20 can be easily held over the touch sensor, and at this time, it is not necessary to remove the neck strap 10 from the chest. Further, when the microphone 70 is disposed inside the plug 18 when used as a headset, the shield wire of the microphone 70 can be completed inside the microphone, and the cord 17 wound up by the winding device is only an audio signal. Therefore, since the wire configuration is simple and the cord 17 can be made thin, the winding portion can be reduced in size and weight and the durability can be improved by preventing the cord from being disconnected. Further, when the excess portion of the cord 17 with the connecting plug is wound by the winding device 85 (see FIG. 1), or when this portion of the cord 17 is used as a curled cord, the excess portion of the cord 17 may protrude. Disappear.

  That is, a surplus portion of the cord 17 that is drawn from the side portion of the connecting member 16 of the cord 17 and that connects the plug 18 to the tip is wound by the winding device 85. Such a winding device 85 is composed of integrally molded rubber as described above. 9A and 9B, such a winding device places the flanges 87 on both sides of the winding portion 86 away from each other, winds the cord 17 on the winding portion 86 in this state, 9C, the flanges 87 on both sides are elastically deformed so that the outer peripheral edges thereof are close to each other or come into contact with each other, as shown in FIG. 9C. Therefore, as shown in FIG. 9C, the surplus cord 17 is wound in a substantially spherical winding device, whereby the surplus cord 17 is easily processed.

  Although the present invention has been described above with reference to the illustrated embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea of the present invention. For example, the engagement structure between the connecting member 16 and the cylindrical mouth portion 15 of the winding device 13 in the above embodiment does not necessarily need to be a structure using the clip spring 58, and any other various engagement structures can be used. Can be selected. Moreover, this hanging device is not necessarily limited to the hanging device of the mobile phone 20, and can be widely used as a hanging device for other various portable electronic devices.

  The present invention can be widely used as a hanging device for hanging a mobile phone with a neck strap.
