Description

  The present invention relates to a device for storing a headphone unit.

  As a prior art of an apparatus for storing an earphone (headphone) unit that reproduces sound by being applied to the left and right auricles, there is an electrical component storage case with cord shown in Patent Document 1. When storing, open the case and pull the cord, put the unit at the end of the cord in the case, fit it in and fix it, and close the case. When using, open the case, remove the inserted unit, pull out the unit, adjust the pinch position for fixing the cord and close the case. It takes time and effort during storage and use, and it cannot be used for different earphones, and is heavy.

 Patent Document 2 discloses a conventional technique of an earphone (headphone) cord that is relatively easy to handle. The root portions of the left and right units of the earphone are sandwiched in two concave portions of the clip and fixed. In use, it is easy just to open the clip. However, when storing, the roots of the left and right units are positioned in the two recesses of the clip, and it takes time to hold the clip while holding each. Moreover, it cannot be used for different earphones. The cord is wrapped around the unit's bent part or near the clip and easily entangled.

  Patent Document 3 discloses a conventional technique for preventing the headphone cord from being tangled. The cord is stored in a curl shape in the elastic bellows means. The problem is that the bellows means becomes long, and it takes time to store the cord, or it is difficult to store it sufficiently. Moreover, it cannot be used for different headphones.

  As a conventional technique for reducing the cord entanglement of the headphones, there is a technique using a small part that has two cords that pass through a cord branched to the left and right and are made movable. A mechanism is used in which a small part can be moved to the vicinity of the cord branching part when used and the unit can be attached to the ear, and when it is not used, it moves to the base part of the headphone unit so that the unit is not largely separated. It is easy to operate, small, and has few parts burdens, but the cord tends to get tangled near the bent part or the base of the unit, which is not enough to prevent the cord from getting tangled. Also, when the cord touches the clothes and rubs, noise is generated along the cord.

The arc-shaped umbrella portion 13 is continuously formed. The left and right units 2 and 3 are stored by holding the headphone unit storage device 1 with one hand and pulling the cord 10 integrated with the other hand in the direction of the central axis.

  In order to store the large left and right units 2 and 3 in the headphone unit storage device 1, it is necessary to expand the shape of the headphone unit storage device 1 in a bag shape in the central axis direction to increase the volume. In FIG. 1, the headphone unit storage device 1 is shown in a non-storage state shortened in the direction of the central axis. In order to make the shape variable in the central axis direction, the outermost cylindrical portion 12 forming the opening 11 is fixed, and the second cylindrical portion 14 from the outside and the second cylindrical portion 14 from the outside are fixed. The portions 15 and 16 between the end portions continuous from the end portions are reversed in the direction of the central axis so that they can be developed in a bag shape.

  The headphone unit storage device 1 shown in the first embodiment includes an outermost tubular portion 12 from the umbrella portion 13, a portion 15 between the end portions, a second tubular portion 14 from the outside, a portion 16 between the end portions, The innermost cylindrical portion 17 and the elastic deformation open portion 19 are continuously formed in an uneven shape with an elastic material such as rubber or soft vinyl chloride resin. The outermost cylindrical portion 12 is relatively thick and relatively high in rigidity, and the portions 15 and 16 between the end portions and the second cylindrical portion 14 from the outside are relatively thin and easily bent and deformed. And the innermost cylindrical part 17 is made relatively thick. An elastic deformation opening 19 having a slit 18 and having a relatively small area is provided at the end of the innermost cylindrical portion 17. The slit 18 is formed in a single shape that passes through the vicinity of the center or is branched in a plurality of directions from the vicinity of the center.

  The slit 18 of the elastic deformation opening 19 has a width narrower than the diameter of the branched cords 8 and 9, and the branched cords 8 and 9 are easy to move in the direction of the central axis. The deformed elastic force is applied to the branched cords 8 and 9. Moreover, it is made into the elastic deformation open part 19 which has the slit 18 of the length and shape which lets the headphone terminal 20 provided in the end of the integrated code | cord | chord 10 pass, and the branch part 21 which may be enlarged. The elastic deformation opening portion 19 corresponds to the bottom of the innermost cylindrical portion 17 or a bag-like bottom formed by developing the headphone unit storage device 1.

  FIG. 2 is a cross-sectional view showing a state in which the headphone unit storage device 1 shown in the first embodiment of FIG. 1 is deployed in the central axis direction and formed into a bag shape and the left and right units 2 and 3 are stored. Only the headphone unit storage device 1 is shown in a sectional view. The bent portions 4 and 5 and the root portions 6 and 7 of the left and right units 2 and 3 are concealed inside the bag-shaped space, so that the branched cords 8 and 9 and the integrated cord 10 are 3 is not entangled.

  The left and right units 2, 3 are pulled by an integrated cord 10, and the base portions 6, 7 are stopped in the vicinity of the elastic deformation opening portion 19 corresponding to the bottom so that the whole is stored. In the process of being housed, the second cylindrical portion 14 from the outside is continuously connected to the second cylindrical portion 14 from the outside in a state where the plurality of cylindrical portions 12, 14 and 17 are overlapped with a common central axis as shown in FIG. The relatively thin elastic material of the portions 15 and 16 between the end portions is changed in the direction in which the elastic deformation opening 19 moves in parallel with the central axis with bending deformation. The bent portions 4 and 5 of the left and right units 2 and 3 enter the opening 11 without stopping while hitting the umbrella portion 13. When the main deformation is finished, it is stabilized in a deployed bag shape, the branched cords 8 and 9 are stopped by friction by the slit 18 of the elastic deformation opening portion 19, and the left and right units 2 and 3 remain in the bag-shaped space. .

  In order to return from the state in which the left and right units 2 and 3 are stored in the bag shape of FIG. 2 to the non-storage shortened state shown in FIG. 1, the outermost cylindrical portion 12 in FIG. While holding, the left and right units 2 and 3 can be easily pushed out by pushing the elastic deformation open portion 19 corresponding to the bottom or the end of the innermost cylindrical portion 17. When the units 2 and 3 are slightly out, the branched cords 8 and 9 are pulled out to the required length while holding the left and right units 2 and 3. The portion inverted in the process of changing from the shortened state of FIG. 1 to the expanded shape of FIG. 2 is restored to the shape of FIG. The state is shortened in the direction of the central axis.

  FIG. 3 shows a second embodiment. The headphone unit storage device 22 of the present invention is shown in a sectional view shortened in the central axis direction. As shown in the first embodiment, the umbrella portion 23, the outermost cylindrical portion 24, the second cylindrical portion 25 from the outside, the innermost cylindrical portion 26, and the elastic deformation opening portion 27 are elastically uneven. It is formed continuously with materials. The adjacent outermost cylindrical portion 24 and the second cylindrical portion 25 from the outside, and the second cylindrical portion 25 and the innermost cylindrical portion 26 from the outside are alternately continuous at the portions 28 and 29 between the end portions. Is done. The portions 28 and 29 between the end portions are formed of an elastic material relatively thin together with the second cylindrical portion 25 from the outside, and are easily bent and deformed.

  A highly rigid resin material 30 having a cylindrical portion is arranged in close contact with the inner side of the outermost cylindrical portion 24, is made an umbrella shape near the umbrella portion 23, and extends outward. The resin material 30 supplements the rigidity of the outermost cylindrical portion 24 and the umbrella portion 23 so that the opening portion 31 is not crushed even when an external force is applied by hand so that the left and right units 32 and 33 can be easily accommodated. . In addition, the friction when the left and right units 32 and 33 move by hitting the periphery of the opening 31 is reduced, and the left and right units 32 and 33 can be easily entered from the opening 31. By arranging the resin material 30, the required rigidity can be ensured even if the outermost cylindrical portion 24 and the umbrella portion 23 are thinned, and the weight can be reduced. The process of storing the left and right units 32 and 33 from the shortened state in the headphone unit storage device 22 of FIG. 3 is the process of storing the left and right units 2 and 3 of the first embodiment shown in FIGS. The same.

  FIG. 4 is a sectional view showing a third embodiment of the headphone unit storage device of the present invention. A hole 36 parallel to the central axis is formed in the vicinity of the innermost cylindrical portion 35 of the headphone unit storage device 34. Although the center of the hole 36 is formed inside the innermost cylindrical portion 35 in FIG. 4, it may be arranged at a position coincident with the innermost cylindrical portion 35 or on the outer side. A clip 38 having a shape approximating the hole 36 and having a slightly thick cross-sectional protrusion 37 is integrated into the headphone unit storage device 34 by fitting the protrusion 37 into the hole 36.

  The clip 38 having the protruding portion 37 is integrally formed of a relatively soft resin material, and a metal leaf spring 39 is disposed inside the operation portion 40. The headphone unit storage device 34 is fixed by pinching the collar or chest pocket of the clothes with the pinching portion 41, and the branched cords 42 and 43 are set to an appropriate length from the ear. In use, sagging and shaking of the branched cords 42 and 43 or the integrated cord 44 are reduced. Furthermore, by making each cord difficult to rub against clothes and stopping each cord with the elastic material of the elastic deformation opening 45, the level of noise that propagates through the branched cords 42 and 43 and enters from the left and right units can be reduced.

  FIG. 5 is a perspective view showing the headphone unit storage device 34 of the third embodiment of the present invention in which the clip 38 shown in FIG. 4 is integrated. The headphone unit storage device 34 has the same form as the headphone unit storage device 22 shown in the second embodiment of FIG. A resin material 47 is arranged outside the umbrella portion 46 of the elastic material on the outer side in the central axis direction. The shape of the end of the resin material 47 does not necessarily need to be circular as long as it has a function of easily storing left and right units (not shown). The color of the resin material 47 can be different from that of the umbrella portion 46 and the inner portion 48 of the elastic material. As a result, the range of designs that can be selected can be widened.

  The clip 38 is fixed in close contact with the headphone unit storage device 34, and the outer shape of the clip 38 is made relatively small and smooth, so that the cords 42 and 43 that are branched and the integrated cord 44 are hardly entangled. .

  FIG. 6 shows Embodiment 4 of the headphone unit storage device of the present invention. A headphone unit storage device 49 is shown in cross-section. The outermost cylindrical portion 50 from the outside, the second cylindrical portion 51 from the outside, the third cylindrical portion 52, the fourth cylindrical portion 53, and the innermost fifth cylindrical portion 54 are the center. The shafts are arranged so as to overlap each other, and the end portions of the cylindrical portions are alternately connected by the portions 55, 56, 57, and 58 between the end portions, thereby forming a continuous uneven shape with an elastic material.

  Even-numbered cylindrical portions 51 and 53 from the outside, and portions 55, 56, 57 and 58 between the ends connected to the ends of the cylindrical portions 51 and 53 are continuously formed of a relatively thin elastic material. When the integrated cord 59 is pulled in the central axis direction and the base portions 62 and 63 of the left and right units 60 and 61 hit the elastic deformation opening portion 64, or a relatively thin elastic material portion is bent before hitting. While being deformed, it is inverted in the direction of the central axis (from the top to the bottom in FIG. 6), the headphone unit storage device 49 is developed in a bag shape, and the left and right units 60 and 61 are stored inside.

  When the number of the plurality of cylindrical portions is increased, when the bag-like depth for storing the left and right units 60 and 61 is made constant, the height of the individual cylindrical portions in the central axis direction can be reduced. The outer shape can be reduced by reducing the height of the state where the shape portions are overlapped.

  A through-hole 67 may be formed in the elastic deformation opening 64 that is passed through the branched cords 65 and 66 and is stopped. Unlike the slits 18 shown in the first and second embodiments, it is necessary to change the shape and diameter of the through hole 67. Therefore, the elastic material in the vicinity of the through hole 67 may be relatively thin. The through-hole 67 needs to pass the headphone terminal 68 and the branching portion 69, and may be used together with the slit 18 shown in the first embodiment.

  You can store and take out the unit with a simple operation, regardless of the type or shape of the headphones that will fit inside the auricle of a portable device, reduce cord entanglement, reduce noise caused by rubbing, and select the design Can be wide.
