Description

Retractable wire device with lever lock

The present invention relates to a device for establishing a cord such as an ear microphone, an earphone, and an electric device using a cord used in a mobile phone or a portable audio device, and more specifically, the bobbin 2 is a double-layered track and the bobbin is fixed. The lever lock 5 is provided for repetitive withdrawal as long as necessary for use (at this time, the withdrawal is artificial force), and the formulation is automatically performed by the whole bobbin 2 due to the spring spring provided in the bobbin 2. The present invention relates to a winding device having a lever lock that can be driven to prevent entanglement and twisting of earphone strings and to facilitate storage.

In general, earphones are used in hands-free or portable audio devices of mobile phones. Currently, hands-free products include speakers in the earphone case, microphones in the earphone string, and earphones and microphones in the earphone case, but these earphones do not have a winding device. Occurs and storage problems exist. As a way to solve this problem, there is a device that automatically establishes the cord. In this method, the cord of the plug is fixed and the portion of the cord to be wound must be rotated. It must be separated and must be separated, and this separated part is configured to be connected while rotating the contact terminal again. However, this is undesirable because it causes durability and contact noise in the future.

And since the earphone case of the side open type earphone cord bidirectional winding function of Korea Patent Publication No. 2000-0063791 is made in a straight shape, most of the earphone strings are drawn out of the case at the time of establishment. If the repetition of drawing and sizing occurs, the wear of the take-up roll may occur due to the friction between the ball and the take-up roll, which may cause a malfunction. There is also a problem that causes a malfunction.

In addition, the disadvantages inherent in the automatic sizing device consisting of a fault orbit of the conventional sizing method will be described with reference to FIG. When the rope is stopped at any length by pulling the rope, as shown in the drawing, the stop is only possible if the bobbin stop pin spring is between 3-1 and 3-2, which is 1/2 of the track. The cycle may cause an inoperable state that cannot be stopped. In addition, when switching to rewinding by slightly pulling the string again from the bobbin stop state, it is possible only between 3-3 and 3-4, so an inoperable state such as 50/100 may occur.

The present invention to solve the above problems;

The track surfaces 8 and 9 and the bobbin fixing part 14 are formed on the side of the bobbin 2 on which the cord is wound so that the bobbin fixing lever lock 5 can be stopped and the rotation of the bobbin 2 is pulled out. The artificial artificial force, ie physically withdrawal and winding of the cord 3, is automatically established using a separate spring-loaded spring (for automatic driving) inside the bobbin. In addition, the length of the cord (3) is arbitrarily accurate so that the bobbin (2) is composed of a double-orbit track, the first floor is a dedicated track (8) required for stopping, the second floor is a dedicated track (9) required for winding. It is an object of the present invention to provide a winding device having a lever lock, characterized in that configured.

The constitution and principle of the present invention for achieving the above object are as follows.

FIG. 2 is a front view of an automatic rewinding duplex track according to the present invention, in which a bobbin stop bobbin fixing lever lock 5 changes a traveling direction from a first track 8 to a second track 9; 10), the part 2 in which the first orbital plane 8 is connected to the second orbital plane 9, and the bobbin 2 rotate. In the arbitrary stop, the bobbin fixing part 14 and the bobbin 2 rotate direction A space for allowing the bobbin fixing lever lock (5) to automatically change direction by a guide (13) for automatically turning the bobbin fixing lever (5) so that the bobbin (2) can start rewinding after stopping. (12), the first track surface (8), the second track surface (9), the bobbin rotational central axis (7), the part which easily turns the track stop fixing lever (5) by physical force when the cord is pulled out ( 12), and the principle of fixed disassembly is that the bobbin fixed lever lock 5 is normally in a straight line due to the tension of the tension spring 6 It is guided and fixed at the bobbin fixing part 14 by the trajectory of the bobbin. When the cord 3 is pulled out or wound up, the lever lock 5 is guided in a straight line at the turning parts 12 and 13, and thus the lever lock 5 is reversed in the bobbin fixing part 14 during the winding operation. Up to full winding. When the stop at the desired length is fully wound, the lever lock 5 is turned upward when the lever lock 5 is turned upward at the turning part 12 so that the bobbin 2 is fixed at the bobbin fixing part 14. .

Hereinafter, with reference to the accompanying drawings, preferred configurations and embodiments of the present invention will be described in detail.

Figure 3 is an exemplary view showing the process of drawing out and automatic establishment of the string according to the present invention;

1 in FIG. 3 shows a state where the cord 3 is completely wound in both directions and the lever lock 5 is directed downward. As shown in ②, when the cord 3 starts to be pulled out in both directions, the bobbin 2 starts to rotate counterclockwise about the bobbin rotation shaft 7. Subsequently, when the cord 3 is pulled out, the lever lock 5 is straightened by the tension spring 6 in the space 12 for changing the fixed lever direction on the two-orbit plane 9 as in e. If it is pulled out more, the lever lock (5) is completely changed direction as shown in ④ and is directed upward. 5 indicates the state in which the cord 3 is continuously drawn out and completely drawn out. At this time, the lever lock 5 is lowered to the one orbit plane 8 while maintaining the changed direction. When the cord 2 is released in this state, the rotation (driving) state of the bobbin 2 is reversed (clockwise) by a spring spring (not shown) for reversely rotating the bobbin 2 as shown in ⑥. The lever lock, which starts to rotate (drive) and faces upward, enters the inclined surface 11. As shown in ⑦, it enters the two orbiting planes 9 from the first orbital plane 8 and is caught by the fixing unit 14, thereby maintaining the drawn state.

The automatic setting of the cord 3 is carried out after the cord 3 is pulled out a little so that the lever lock 5 is located in the lever lock 5 direction turning part space 13 when the lever lock 5 is wound as shown in ⑧. As shown in the main surface ⑨, the fixing lever 5 is pushed by the fixing portion 14 in the second orbiting surface 9 to be turned downward. When the bobbin 2 is continuously rotated, the bobbin 2 descends from the second orbit 9 to the first orbit 8, and the lever lock 5 is continuously positioned downward until the cord is fully established. (2) rotates in the reverse direction (clockwise) continuously by the restoring force of the spring, so it is completely rewound and finally has the same shape as ①. Therefore, withdrawal and automatic winding of the cord (3) is automatically established while the circular motion to repeat from ① to ⑩ of FIG.

Hereinafter, looking at the operation of the present invention as described above;

Since the fixed lever is connected by the tension spring 6, it is easy to move up and down, and the bobbin fixed lever lock 5 can be arbitrarily driven to reduce the cost according to the material savings. It is possible to withdraw only as long as the length of the, can be plugged into the main body (communication, sound) to be used or withdraw the cord 3 in a fixed state. And since the code (3) can be automatically established can be applied to any device that uses the code to prevent tangling and twisting of the line and has the advantage of easy storage. In addition, the length of the cord (3) can be arbitrarily adjusted within the limit length because the structure of the track can be stopped anywhere in the 360 ° direction even if the line is arbitrarily placed at the time of withdrawing the line. It can be switched to the ear microphones, earphones and cords of household appliances using cords, etc. can be used.

Recently, when mobile phone call bans using hands while driving is being made in Korea as well as abroad, the same codes as existing ear microphones or earphones are used in the process of becoming an essential item in accessories. It contains many problems such as after-sales code processing problem, especially driving obstacles caused by unnecessary line length during operation, and problems with existing code winding devices and new method of safe code winding. An apparatus is required.

The cord winding automatic device manufactured by the present invention is designed to meet the above demands. It is a device with many advantages such as durability of the product due to overwinding.
