Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for accommodating cords and the like used in various electric devices.

[0002]

2. Description of the Related Art As a conventional cord accommodating device of this type, a cord winding device for accommodating, for example, a cord incorporated in various electric devices so that the cord of the device can be pulled out is general. By the way, since the reel device rotatably accommodates the reel in the case, the plane of the case is formed into a substantially circular shape. Therefore, it suffices if a space corresponding to this circular case can be secured in the device, but it is impossible to install in a place without such a space, for example, in a place where there is only a long and narrow installation space. There was a problem that it could not be installed virtually.

Therefore, the present invention solves the above-mentioned conventional problems, and there is no space corresponding to a circular case,
In particular, it is an object of the present invention to provide a cord storage device that can be installed even in an elongated installation space and can efficiently extract and store a cord.

[0004]

In order to achieve the above-mentioned object, the invention of claim 1 stores a rotary member around which a cord is wound in a substantially rectangular case so as to be movable in the longitudinal direction thereof, and to rotate the rotary member. An urging member that constantly urges the body to one end side of the case is provided, and a cord pull-out port and a cord take-out port that pull out the cord wound around the rotating body by moving the rotating body against the urging member are provided. It is provided on the other end of the case. According to a second aspect of the present invention, in the first aspect, the rotating body is movable by engaging its central axis with a groove formed in the wall of the case. According to a third aspect of the present invention, in the first or second aspect, a plurality of rotating bodies are provided, a fixed rotating body is provided on the other end side of the case, and the cords are alternately wound around these rotating bodies. It is like this. According to the invention of claim 4, in any one of claims 1 to 3,
A stopper member that stops the pulled-out cord against the biasing member is provided at the cord pull-out port.

[0005]

With the above-mentioned structure, it is possible to install the cord even in an elongated installation space, and the cord can be pulled out from the case and stored.

[0006]

1 and 2 show a first embodiment of the present invention, FIG. 1 is a vertical sectional front view thereof, and FIG. 2 is a transverse plan view thereof. Reference numeral 1 is a substantially rectangular case, and a rotating body 3 around which a cord 2 is wound is housed in the case 1 so as to be movable in the longitudinal direction. The rotating body 3 is composed of a substantially U-shaped support portion 4 and a rotating roller 6 which is arranged inside the support portion so that both ends of the central shaft 5 penetrate the support portion 4. The rotary roller 6 is composed of a winding portion 7 around which the cord 2 is wound and flange portions 8 provided on both sides of the winding portion 7. The rotating body 3 configured as described above is movably supported by engaging both ends of the central axis 5 thereof with linear grooves 10 formed on the left and right side walls of the case 1 so as to face each other. Further, the rotating body 3 is always urged toward the one end side of the case 1 by the spring 11 attached to the case 1 by the supporting portion 4.

Reference numeral 12 is a cord take-out port provided at the other end of the case 1, and the cord 2 is fixed at one end thereof by a protrusion 14 at the port. Similarly, 13 is a cord outlet provided on the other end side of the case 1, from which the cord 2 fixed by the protrusion 14 at the outlet 12 and wound around the winding portion 7 of the rotating body 3 is pulled out to the outside. It is supposed to be. 15
Is a stopper member for stopping the cord 2 pulled out from the outlet 13 against the spring 11, and a stopper piece 20 pivotally supported by a pin 17 on a bracket 16 provided on the case 1 and having a pressing portion 18, A spring 21 is provided between the pressing piece 18 of the stopper piece and the case 1 to urge the pressing piece 18 toward the inside of the case 1, and a pressing piece 18 of the stopper piece 20.
And a cord receiving portion 23 provided in the case 1 facing the above.

The operation of the above configuration will be described. When the cord 2 is pulled out from the pull-out port 13 in the illustrated state, the rotating body 3 moves in the direction of the arrow against the spring 11, and the movement amount of the cord 2 allows the cord 2 to be pulled out. At this time, the stopper piece 20 of the stopper member 15 is slightly pushed outward of the case against the spring 21 by the pressing portion 18 that is in sliding contact with the cord 2 to allow the cord 2 to be pulled out. When the pulling out of the cord 2 is stopped at the predetermined pulling position, the cord 2 tries to move in the original direction by the force of the spring 11, but at this time, the movement is stopped by the stopper member 15 and stopped at the predetermined position. . That is, the stopper piece 20 of the stopper member 15 presses the pressing portion 18 against the cord 2 by the force of the spring 21, whereby the cord 2 is held between the pressing portion 18 and the receiving portion 23, and the movement is stopped.

3 and 4 show a second embodiment of the present invention,
1 is a vertical sectional front view thereof, and FIG. 2 is a transverse plan view thereof. The second embodiment differs from the first embodiment in that a plurality of rotating bodies 3 (two in this example) are provided in the vertical direction,
A fixed rotating body 3a is provided on the other end side of the case 1 so as to be located at an intermediate position between the rotating bodies 3 and 3, and the cord 2 is wound around the rotating bodies 3, 3a and 3 alternately to twist the cord inside the case 1. The point is that it can be stored for a long time. Since other configurations are the same as those of the first embodiment, the same reference numerals are given to the same portions and the description thereof will be omitted.

Also in the above case, the cord 2 is pulled out from the outlet 13.
When the cord 2 is pulled out, the rotating bodies 3 and 3 move in the direction of the arrow against the springs 11 and 11, and the cord 2 can be pulled out by the amount of movement, and when the pulling out of the cord 2 is stopped at a predetermined pulling position, It is stopped by the stopper member 15. As described above, in the case of this embodiment, the cord 2 having a length twice that of the first embodiment can be stored by simple calculation.

Incidentally, the rotating bodies 3 and 3 shown in the above respective embodiments.
The configurations of a, the spring 11, the stopper member 15 and the like are merely preferable examples, and various other designs can be adopted upon implementation. Further, in the embodiment, both ends of the central shaft 5 of the rotating bodies 3 and 3a are engaged with the linear grooves 10 formed in the wall of the case 1, but without forming the grooves,
The inner wall of the case 1 is recessed, and the rotating body 3, 3
You may make it engage both ends of the central axis 5 of a.

[0012]

Since the invention of claim 1 has the above-mentioned structure, it can be installed in a place where it could not be installed conventionally, that is, in a place where there is only an elongated installation space, and the cord can be pulled out and stored efficiently. be able to. According to the invention of claim 2, the rotation body can be smoothly moved. The invention of claim 3 can store a longer cord. According to the invention of claim 4, the cord can be easily stopped after being pulled out.
