DESCRIPTION JPH04110090
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the
improvement of the cord portion of an ear tray system used in portable cassette players and the
like.
[0002]
2. Description of the Related Art Except for the wireless type, the ear receiver is connected to the
cassette player by a code.
[0003]
[Problems to be Solved by the Invention] The cord for the ear receiver was sometimes entangled
during use and storage.
This is because the cord for the ear receiver is thin and the receiver part is easily caught. It is
often entangled by simply putting unused ear receivers in a pocket etc. In the case of more
random handling, the cord may be broken due to the entanglement of the code. .

For this reason, various cases for storing in a state of being wound with an ear receiver have
been commercially available. However, when the receiver is not used, it is a tedious task to store
it in the case one by one, and it is necessary to actually use the case when going on a trip, or
when using an earpiece. I think it was limited to cases where the bar is not used for a long time.
Moreover, although there also existed a thing which made the length of the code part different
by right and left, it was not an effective method to prevent the connection of a cord.
[0005]
The particularly entangled portion of the receiver bar code is in the vicinity of the bifurcated
portion of the code leading to the left and right receivers and in the vicinity of the receiver main
body portion, and the entangled cord is present in these portions. It was the hardest to loosen.
The present invention prevents the entanglement of the receiver code without using a case body
or the like.
[0006]
[Means for Solving the Problems] Of the two reciprocator codes wired in a Y-shape, of the two
cords on the side of the reciprocator from the bifurcated portion, A continuous concave portion
is formed in the cross-sectional shape of one of the codes, and a convex cross-sectional portion
which can be fitted into the concave portion is continuously formed in the other code. A slider is
provided between these two codes, and the upper and lower portions of the slider separate or
integrate the receiver codes. If one of the two codes has a circular cross-sectional shape, the code
itself can be used as a convex portion and fitted into the other concave cross-sectional code.
[0007]
When using the ear receiver of the present invention, the slider is lowered to separate the code
so that the receiver portion can be applied to both ears. When the ear receiver is not used, the
slider is raised to make one code, preventing the entanglement of the code, and at the same time,
the storage of the code can be simplified, as in the monaural earphone. It is possible to handle
the Further, according to the method of the present invention, since the length of the code of the
bifurcated portion can be set arbitrarily, it can be used in the optimum state in accordance with
the physical constitution and the use form of the user.

Next, specific embodiments of the present invention will be described based on the drawings. The
stereo receiver code is usually wired in a Y-shape. In the example shown in FIG. 1, a convex
portion is formed on the cross-sectional shape of the code 2 connected to the left receiver, and a
concave portion is formed on the cross-sectional shape of the code 3 connected to the right
receiver. Portions are formed, and these uneven portions are configured to function as band-like
fastening vinyl fasteners. The slider 4 provided between the reciprocator cords slides or
separates or integrates the two cords of the fastener body by sliding as in the case of a normal
fastener. can do. 2 and 3 are cross-sectional views showing a state in which the receiver code of
the present invention is integrated.
[0009]
The code 2 shown in FIG. 2 has a convex portion for fasteners formed along a shield material
portion for covering the lead wire. In the case of FIG. 3, the cross-sectional shape of the code 2 is
substantially circular as in the case of the conventional code material, and the code 2 itself is
inserted into the concave cross-sectional portion of the code 3. Be In FIG. 4, the slider 4 and the
receiver portion 1 are provided with mutually engaged portions, and when the slider 4 is fully
pulled up, the slider and the left and right receiver portions Shown is configured to be fixed. In
this example, the base portion of the reservoir is formed of a resin cover 5 having a crosssectional shape close to a cylinder or a square slightly thicker than the reservoir code, and the
guide hole end of the top surface of the slider 6 is formed for engagement with the resin cover 5.
When the cross-sectional shape of the resin cover 5 is similar to a square or a rectangle, by
connecting them, the slider 4 and the resin cover portion 5 can be prevented from being twisted.
[0010]
FIG. 5 shows an example in which a fastening portion 7 for connecting the left and right receiver
portions 1 to each other is provided. After raising the slider to unite the two receivers, when
force is applied to separate the receiver, the slider is lowered and the receiver is separated.
However, these problems can be prevented by the methods shown in FIGS. 4 and 5.

Although each drawing in the present embodiment is a receiver code of the type in which the
lengths of the left and right cord parts are the same, receiver cords of different lengths are also
unified by this configuration. It is possible to Conventionally, for example, a mechanism has been
considered that prevents the slider from moving by turning back the handle portion of the slider.
However, by adopting this structure also for the method, the receiver can be used. The code may
be fixed.
[0012]
The specific embodiments of the present invention have been described above. Although various
designs have been made with respect to the vinyl fastener body and the slider, the present
invention does not particularly limit the shape, configuration, material, etc. of the fastener
portion body.
[0013]
[Effects of the Invention] When the receiver is not used in the ear receptive cord of the present
invention, the cord is formed by unifying the bifurcated part of the cord. At the same time, it is
easy to take up and store at the same time, and when using the receiver, lower the slider to
separate the receiver into an optimal length. It is possible.
