Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a cord winding device installed in electrical equipment.

(B) Prior Art As shown in FIG. 1, in a conventional cord winding device of this kind, a cord winding reel 1 has a cord winding section 3 for storing a winding part of an electric cord 2, and a cord winding part 3 for storing a winding part of an electric cord 4. The take-up part 5, the spring storage part 7 for storing the mainspring spring 6, etc. are sequentially laminated, and the electric cord 4 and the electric A connection accommodating part 9 for accommodating a connection part 8 with the cord 2 was formed. Therefore, when the electric cords 2 and 4 are band-shaped cords, the connecting portion 8 is formed in multiple stages, and the winding portion 5 has a dimension l.
When the laminated size L is larger than that of the cord winding reel 1, the thickness M of the cord winding reel 1 becomes larger, resulting in an increase in the size of the device. (For example, the cord winding device filed as Utility Model Application No. 56-42868 (see Utility Model Publication No. 17978) To provide a cord winding device in which an increase in thickness of the cord winding device due to a connecting portion of an electric cord when a spring storage portion and a spring housing portion are laminated is reduced.

(d) Means for solving the problem The present invention forms a cord winding part on one side of a cord winding reel with a cord winding part formed on the peripheral edge, and a cord winding part is formed on one side of the cord winding reel, and a cord winding part is formed on one side of the cord winding reel. A connection part for the electric cord wound on the cord winding part and the cord extra winding part is arranged in the cord winding part, and a spring for unwinding the cord winding reel is connected to the other side of the central part of the cord winding reel with a partition plate in between. The problem can be solved by means of forming a spring accommodating part and forming a concave part in the partition plate into which one end of the connecting part is inserted so as to be recessed into the spring accommodating part.

(E) Function The present invention absorbs the increase in size by housing the electrical cord connection part in a recess formed by immersing it in the spring housing part.

(F) Embodiment The present invention will be explained based on an embodiment shown in FIGS. 2 to 7.

11 is a cord winding reel 12;
The main body of the cord winding device consists of a pivot plate 14 that pivots the cord winding reel 12 with a pin 13.
The annular cord winding section 15 has a generally U-shaped cross section and is open toward the outer periphery; a partition plate 16 that is integrally formed to close an opening at the inner center of the winding section 15; and the partition plate 16 and the partition plate. It is composed of a spring storage section 17 formed on the outer surface of the winding section 15 on the side, and a cord extra winding section 18 formed on the outer surface of the central opening side of the winding section 15. A through hole 19 formed in the center of the partition plate 16
A cylindrical pin 13 is inserted through the cylindrical pin 13 to bring the pin 13 into contact with the pivot plate 14, and a screw 20 is screwed into the pin 13 from the opposite side of the pivot plate 14 to pivot the pin 13. In addition to being fixed to the plate 14, the reel 12
is pivotally supported on a pivot plate 14 by this pin 13. At this time, the spring storage portion 17 is connected to the pivot plate 14.
It is occluded by providing . The pin 13
An insertion hole 21 is formed in the center, and the insertion hole 2
A through hole 22 communicating with the pivot plate 14 is formed in the pivot plate 14. The spiral spring 23 housed in the spring storage section 17 has its outer end locked to the outer wall of the storage section 17 and its inner end locked to the pin 13 at a proper position. An electric cord 24 connected to an arbitrary device such as a fan motor is wound around the cord winding section 15, and the wound end is connected to the cord winding section 15.
The central part 2 is inserted through the insertion hole 25 formed in the wrapping wall.
Drawn to 6. The retracted end of the electric cord 24 is connected to an electric cord 27 having a smaller diameter than the cord 24 . Both electrical cords 24,
The connecting portion 28 of 27 is held between the inner circumferential side surface of the central portion 26 by a cord holding boss 29 protruding from the partition plate 16 near the inner circumferential side surface of the central portion 26 . The opening of the central portion 26 is closed by a disk-shaped partition plate 30, and the electrical cord 27 is connected to the partition plate 30 and the winding portion 1.
5 through the gap formed between the center portion 26 and the center portion 26. The partition plate 30 is fixed to the cord holding boss 29 with a screw 31, and has a through hole 32 in the center into which the end edge of the pin 13 fits. When the electric cord 24 is unwound to the maximum,
A tensile force acts on the holding portions of both the electric cords 24 and 27, bending the holding boss 29 and trying to release the holding, but this boss 29
Since it also serves as a mounting boss, it securely holds both the electrical cords 24 and 27 without bending. The electric cord 27 is pulled out into the cord extra-winding part 18, temporarily held by a pin 33 formed on its outer periphery, and then wound loosely inward several times, and then inserted through the pin 13 and attached to the pivot plate. It is pulled out to the back of 14. Pin 13 of electrical cord 27
The end inserted into the cord and pulled out to the pivot plate 14 is fixed to the rotating cord winding reel 12. However, the twisting of the electric cord 27 caused by winding and unwinding the electric cord 24 from the cord winding reel 12 is absorbed by the loosening and tightening of the portion that is wound several times loosely inward in the cord extra winding section 18. be done.

The partition plate 16 connects the electric cord 24 and the electric cord 2.
7 is recessed so as to be recessed into the spring storage part 17, and a recess 34 opening in the center part 26 is formed, and a part of the connecting part 28 facing It is fitted in the place 34. The opening width of the recess 34 is sufficient to allow the connection portion 28 to fit therein, and the distance between the partition plate 16 and the pin 13 in the recess 34 is such that the spring spring 23 in the spring storage portion 17 is wound up during normal use. It goes without saying that the dimensions are such that it can be rewound freely. The mainspring spring 23 in the unwound state is held by the partition plate in the recess 34.
As shown in FIG. 5, it is inevitable that the grooves will be dense on the recess 34 side and coarse on the opposite side, but this will hardly impede the operation. Further, the partition plate 16A at the bottom of the recess 34 is brought into contact with or close to the pivot plate 14.

(g) Effects of the invention Since the present invention is constructed as described above, even a plurality of connecting parts can be stored and held without increasing the size of the entire device, and the device can be made more compact. Further, by forming a recess for storing the connecting portion, the partition plate is reinforced, and deformation damage to the cord reel during winding and unwinding of the cord can be reduced.
