Description

[Detailed description of the invention] This invention relates to a cord reel used in various electrical appliances.It is designed to make it easier to repair broken cords, and at the same time to reduce the number of parts (thus reducing costs). That's what I said.

Generally, a conventional cord reel has two reel bodies 21. as shown in FIG. It is divided into 22 parts, which has disadvantages such as an increase in the number of parts, which takes time to assemble and increases costs.

If a disconnection occurs between the current collection rail 24 and the cord 25 inside the reel body 23, the rotation support shaft 27 and the spiral spring 28 must be removed after the spring cover 26 is removed. It was very troublesome, as 28 had to be extremely careful because there was a risk of it flying out and causing injury.

The present invention eliminates these conventional drawbacks at once, and one embodiment thereof will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a reel made of resin, and flanges 3a and 3b are integrally formed at both ends of the knoll body 2.

An opening 4 is formed in a part of the reel body of the reel 1.

Further, a cross-shaped locking piece 5 is cut out and integrally formed on the opposite side of the reel body 2 from the opening 4.

The end of the horizontal piece of this locking piece 5 is connected to the reel body 2, and the vertical piece is separated from the reel body 2.

Therefore, as shown in FIG. 2, by pressing one end 5a of the vertical piece in the direction of arrow a, the locking piece 5 is rotated about the horizontal piece, and the other end 5b of the vertical piece is turned outward b. It is something that is displaced.

Reference numerals 6a and 6b are elastic pieces formed on the opening edge of one end of the reel 1, and 7 is a bearing portion integrally formed inside the reel body.

Reference numeral 8 denotes a rail base which is inserted into the reel body of the reel 1 through the opening 4 and whose other end is engaged and held by the other end 5b of the locking piece 5, and has an annular current collector in contact with a current collector (not shown). rail 9
a, 9b are provided, and the code 1 is connected to the current collecting rails 9a, 9b.
0 is connected.

Reference numeral 11 denotes a through hole formed approximately in the center of this rail stand 8.

Reference numeral 12 denotes a rotation support shaft fitted into the bearing portion 7 inside the reel body of the rail 1, and a spring case 13 is integrally provided therein.
A spiral spring 14 is provided within the spring case, and one end of the spiral spring 14 is attached to the rotation support 12 and the other end is attached to the spring case 13.

The outer circumferential wall of this spring case 13 is divided into a plurality of parts, which are crimped onto the inner wall of the reel body 2, so that the spring case 13 rotates integrally with the reel body 2. It is engaged with the elastic pieces 6a and 6b to prevent it from coming off.

Further, the rotation support 12 is fitted into the through hole 11 of the rail base 8 at the same time as it is fitted into the shaft portion 7, and is firmly supported in a freely rotatable manner.

Here, the rail stand 8 supporting the rotational support shaft 12 is tilted as shown by the parallel image in FIG. It is now possible to lean towards it.

The rotation support shaft 12 is detached from the through hole 11 of the rail base 8 by the above-mentioned tilting.

Therefore, with this cord reel, if a break occurs between the current collection rails 9a, 9b of the rail stand 8 and the cord 10, the rail stand 8 can only be disconnected by turning the rail stand 8 diagonally and pulling it out as described above. can be removed and broken cords can be repaired.

That is, a broken cord can be easily repaired without removing the rotating support shaft 12 and the spiral spring 14.

However, since the rail stand 8 has the current collecting rails 9a and 9b, it is formed using an expensive material with high arc resistance and heat resistance.However, since the rail stand 8 is independent of the reel 1, the reel There is no need to use expensive materials for 1, and the cost can be provided accordingly.

In addition, the above reel 1 has flanges 3 on both ends of the reel body 2.
Since a and 3b are integrally molded, there is no need to assemble two parts as in the conventional case, which improves productivity and at the same time allows for a reduction in the number of parts.

In the above embodiment, the spring case 13 is provided on the rotational support shaft 12 and the spiral spring 14 is unitized on the rotational support shaft 12, but this can be easily done by simply fitting this unitized part into the knoll barrel 2. This is to make it easier to assemble.
It does not necessarily have to be made into a unit.

That is, one end of the spiral spring 14 may be attached to the rotation support shaft 12, and the other end may be attached to the reel body 2.

As described above, according to the present invention, the number of parts is reduced by making the reel an integral part, so that productivity is improved and the reel can be provided at low cost.

However, the rail stand with the current collection rail is installed so that it can be attached and removed from the opening in the peripheral wall of the reel body, so even if a break occurs between the current collection rail and the cord, you can simply remove the rail stand. Its practical value is great as it is easy to repair and easy to handle.
