Abstract

(57) [Abstract] [Purpose] To provide a cord entanglement prevention device which is easy to entangle and is troublesome to handle because it is flexible and thin, and which facilitates the unfolding and storing of the cord of a stereo earphone. [Configuration] 1. Attach the zipper 5 to each of the opposing ridgelines of the cord 1, which is divided into two left and right legs, and fasten the zipper (5).
When the puller (6) is pulled down to the position of the branch portion (3), the left and right two cords (1) can be separated into a Y-shape. 2. The cord 1 split into two left and right legs is covered with a stretchable tubular bag 6, and one end of the cord 1 is fixed to the branch portion 3 of the main cord 4 and closed. The left and right two cords 1 are passed through the ring 5, and the opening at the other end of the bag 6 is attached around the ring 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a device for preventing entanglement of stereo earphone cords.

[0002]

[Prior art]

 Conventionally, there has been a method of winding a reel-type storage container.

[0003]

[Problems to be solved by this proposal]

 The stereo earphone cord has a structure in which a heavy earphone hangs at each end of a flexible elongated cord that is divided into two left and right legs. When doing this, there was the problem that handling was troublesome because the cord had to be entangled and the nerves had to be taken care not to break the thin cord. The present invention has been made to solve such a problem.

[0004]

[Means for solving the problem]

 Claim 1. Attach the fasteners (5) so that the cord (1) is split into two left and right legs when the puller (6) is pulled down on each of the opposing ridgelines of the cord (1) that is split into two left and right legs. The present invention is a device for preventing the entanglement of stereo earphone cords having the above-mentioned configuration. Claim 2. On the main cord (4), one end of the elastic tubular bag (7) is fixed to the branch part (3) and closed, and the opening at the other end is passed through the left and right cords (1). Attach the bag (7) joined around the circular ring (8). The present invention is a device for preventing the entanglement of stereo earphone cords having the above-mentioned configuration.

[0005]

[Action]

 Claim 1. By moving the puller (6) of the fastener (5) up and down, the cord (1) split into two forks can be combined and separated. Claim 2. When the bag (7) is extended to the joint part of the earphone (2) and the force is relaxed there, the bag (7) contracts while swallowing the cord (1), so the cord (1) ends up in the bag (7). It is stored in 7).

【Example】

Hereinafter, examples of the present invention will be described. Embodiment 1 Embodiment 1 shows a device according to claim 1, and the configuration thereof will be described with reference to FIGS. 1 to 5. That is, as shown in FIG. 1, a fastener (5) is attached to each of the opposing ridgelines of the cord (1) which is divided into two left and right legs of the stereo earphone cord, and the puller (6) of the fastener (5) is attached. 2) is pulled down to the position of the branch portion (3), the left and right two cords (1) can be separated into a Y-shape. With this structure, when using a stereo earphone cord, pull down the pull tab (6) of the fastener (5) to the position of the branching part (3), and draw the two cords (1) on the left and right sides. Branch into a Y shape as shown in 1, and attach the earphone (2) to the ear. When storing this, pull the puller (6) of the fastener (5) together with the two cords (1), and the two cords (1) will be integrated as shown in FIG. So, just roll it up or roll it up and store it. In order to attach the fastener (5) to the cord (1), in the trial production, as shown in FIG. 3, the ear portion of the commercially available fastener (5) was rolled and the cord (1) was sewn in, but as shown in FIG. If the cord (1) and the fastener (5) are bonded, or if the code (1) and the fastener (5) are integrated as shown in Fig. 5, flexibility will be increased and mass production will be easier. For the fastener (5), in addition to the type in which the teeth of a comb are engaged, the type in which the vertical groove is engaged, a type that can be opened and closed by the puller (6), It is also possible to use a type that does not have (6) and that holds the vertical groove by hand or pulls it apart. Second Embodiment A second embodiment shows a device according to claim 2, and the configuration thereof will be described with reference to FIGS. 6 to 8. That is, as shown in Fig. 6, when the cord (4) is fully extended to the branch portion (3), it has the same length as the cord (1) split into two left and right legs. One end of a cylindrical bag (7) is fixed and closed, and the opening at the other end is joined to the bag (7) around the ring (8) that passes through the two cords (1) on the left and right. Install. The inner diameter of the ring (8) should be such that friction resistance is generated to some extent when the two cords (1) on the left and right are inserted and moved up and down. The present invention has the above structure. When storing the stereo earphone cord, hold the branch part (3) of the main cord (4) with one hand and combine the two cords (1) with one hand to make a ring. (8) is pulled up, and the stretchable tubular bag (7) is extended to the joint portion of the earphone (2). Then, when the force is relaxed, the bag (7) contracts while swallowing the cord (1), and as a result, as shown in FIG. 8, the bag (7) is rolled and stored small. When using this, hold the ring (8) with one hand and pull out the earphone (2) from the bag (7). Then, the cord (1) comes out of the bag (7) without being entangled, so it is branched into two left and right legs and attached to the ear. After mounting, the bag (7) should be shrunk slightly as shown in Fig. 7 so that it does not get in the way. In the trial production, a thin silk fabric was bias-cut and used as the material for the bag (7), but it was light and not bulky, slipped well, and felt good.

[0007]

[Effect of device]

 Due to its flexibility and thinness, the cord of the stereo earphone, which is easily entangled, is less likely to be entangled when unfolding and storing, making it easier to handle.
