Description

[Detailed description of the invention] The present invention relates to a cord holding device, and its purpose is to easily hold the cord by simply inserting it into a slit, improving work efficiency, and to improve workability even when the cord is flat. To provide a highly versatile cord holding device capable of holding even a round code.

Hereinafter, one embodiment of the present invention will be specifically explained by applying it to an electric fan. First, the first part shows the overall configuration of the electric fan.
In the figure, 1 is a base having a column 2, and 3 is a fan head supported on the upper end of the column 2 via a neck bearing 4 so that the angle of elevation can be adjusted and the head can swing. Reference numeral 3 is a case 5 in which a motor, a swinging mechanism, etc. are housed, and a plastic cover 6 is placed over it.A blade 8 is attached to the rotating shaft 7 of the motor, and the blade 8 is covered with a protective net 9. There is. Further, 10 is a switch provided on the base 1, and 11 is an intermediate cord connecting between the switch 10 and the motor. Next, in FIG. 2, reference numeral 12 denotes a cord holder integrally molded on the plastic lid of the case 5, and a holding plate 13 corresponding to the plate-shaped part has one end open at one side edge of the holding plate 13. A slit 14 of a predetermined length is formed. The open end of the slit 14 serves as an opening 15 for insertion of a cord, and the portion of the slit 14 on the side of the insertion opening 15 is widened outward so as to gradually become wider. Also, slit 1
A wide portion 16 is formed in the middle of the slit 4 by notching both side edges of the slit 14 into a substantially semicircular shape, for example. In this case, the notches 17 and 18 constituting the wide portion 16 are formed substantially opposite to each other and shifted by a predetermined amount in the direction in which the slit 14 extends, which is the direction in which the cord is inserted.

The intermediate cord 11 is held by the holding plate 13, and when the fan head 3 is adjusted in elevation or tilted, tensile force is repeatedly applied to the connection part with the motor, and the cord breaks. I try not to let that happen. As the intermediate cord 11, if the neck bearing 4 is attached to the support 2 and the fan head 3 is supported at a certain height, a flat cord 11A having core wires arranged in parallel as shown in FIG. 3 is used. In the case where the height of the fan head 3 can be adjusted by attaching the neck bearing 4 to the lifting column supported by the support 2, the core wires are twisted as shown in Fig. 4. An ivy round cord 11B is used.

Now, in order to hold the flat cord 11A on the holding plate 13, it is sufficient to insert the middle portion of the flat cord 11A into the slit 14 through the insertion opening 15 to the innermost part thereof. Then, the both side edges of the slit 14 strongly bite into the vinyl coating of the flat cord 11A, and the flat cord 11A is held between them.
It is held by the holding plate 13 in a state where it is prevented from coming off from the frame and from moving in the vertical direction (see FIG. 5).

Further, in order to hold the round cord 11B, the middle portion of the round cord 11B may be inserted into the slit 14 through the use opening 15 and fitted into the notches 17 and 18. Then, notch 1
The peripheral edges of the round cords 7 and 18 strongly bite into the vinyl coating of the round cord 11B and hold the round cord 11B, so the round cord 11B is attached to the holding plate 13 in the same state as the flat cord 11A. (See Figure 6). In this case, both notches 1
7 and 18 are formed substantially opposite each other and shifted by a predetermined amount in the cord insertion direction, so that the round cord 11
Since B is distortedly deformed and tries to return to its original circular state, the elastic restoring force causes it to come into even stronger contact with the inner edges of the notches 17 and 18, so that its holding becomes stronger and more reliable. In this way, the round cord 11B is strong due to the elastic restoring force at the notch 1.
Since the wires are held in contact with the inner edges of the wires 7 and 18, even if the number of core wires is different and the outer diameter size is different, the wires can be reliably held in the notches 17 and 18, further improving versatility. By the way, in the case of the flat cord 11A, even if the number of core wires is different, the flat cord 11A
There is no change in the thickness of the core wires, and the slits 14 can securely hold them almost regardless of the number of core wires.

Although the above embodiments have been described with reference to the case of holding intermediate cords, they may also be applied to holding power cords, and can be widely applied to holding cords in electrical equipment, not just electric fans. .

As explained above, the present invention allows the cord to be held simply by simply inserting it into the slit, making the cord holding work extremely efficient.Moreover, whether the cord is flat or round, In particular, round cords can be held reliably even when the outside diameter dimensions differ, and the cord holding device is highly versatile, so it is possible to provide a cord holding device that can cope with differences in the shape of the cords used with a single slit. .

Claims (1)

[Scope of utility model registration request] A slit for holding a flat cord is formed in the plate-shaped part, one end of which is opened at one side edge of the plate-shaped part, and this slit is used as an opening for inserting the cord, and approximately halfway between both edges of the slit. A cord holding device characterized in that round cord holding notches are formed so as to face each other and to be shifted by a predetermined amount in the cord insertion direction.
