Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a cord winding device having a heat dissipation port in the end plate of the reel.

(Prior Art) Conventionally, in cord winding devices, a large number of heat dissipation ports are formed on the outer periphery of the end plate of the reel, and the heat of the cord wound on the reel is dissipated through the heat dissipation ports, thereby cooling the cord. The food is served in a manner designed to achieve this goal. Conventionally, the heat dissipation port is formed by an opening formed in the end plate.

(Problem to be solved by the invention) However, with the above structure, if the opening that constitutes the heat radiation port is blocked by the cord from the inside of the end plate, the heat radiation of the cord through the opening will be Only the part that was in front of the club was performed,
It had the disadvantage of poor heat dissipation.

On the other hand, in order to cope with this problem, it is conceivable to enlarge the openings constituting the heat dissipation ports, but if this is done, there is a situation in which the strength of the end plates is significantly reduced.

The present invention was devised in view of the above circumstances, and its purpose is to provide a cord winding device that can improve heat dissipation from the heat dissipation port, and achieve this while suppressing a decrease in the strength of the end plate. is to provide.

[Structure of the invention] (Means for solving the problem) The present invention is a cord winding device having a large number of heat radiation holes on the outer periphery of the end plate of the reel for winding the cord. , a recess formed in the end plate so as to bulge from the inside to the outside and extend from the outer periphery of the end plate toward the center, and a recess formed to communicate between the inside and outside of the recess. It is characterized by the fact that it is composed of an opening.

(Function) According to the above means, a space is always secured inside the recess in the heat dissipation port, and this space always faces the outside through the opening, so that the heat of the cord is dissipated through the space and the opening. Dissipated.
Further, since the recessed portion of the heat radiation port faces the cord, the surface facing the heat radiation port relative to the cord can be secured by the recessed portion, and there is no need to make the opening large.

(Example) An example of the present invention will be described below with reference to the drawings.

First, in FIG. 1 showing the whole, 1 is a support body, which has legs 2, 2 at the lower part, a handle part 3 at the upper part, and a shaft part (not shown) at the middle part. A cap 4 is attached to the tip of this shaft. Reference numeral 5 denotes a reel rotatably supported by the shaft, which has front and rear end plates 6 and 7 each having a substantially disk shape, and a cylindrical reel supported between both end plates 6 and 7. A body part 8 (only a part of which is shown in FIG. 2) is comprised of a body part 8 (only a part of which is shown in FIG. 2), and an outlet base 10 having three outlets 9 in this case is screwed to the front end plate 6 in the center thereof, and A knob 11 is rotatably attached to the outer peripheral part. 12
is a cord wound around the body 8 of the reel 5, one end of which is connected to each outlet 9, and the other end has a plug 13; by pinching and pulling the plug 13, the reel 5 is It is pulled out with rotation, and is wound onto the reel 5 by gripping the knob 11 and rotating the reel 5.

Now, reference numeral 14 denotes a large number of heat dissipation ports formed in the front end plate 6 of the reel 5. As shown in FIG. A concave portion 15 formed to bulge and extend from the outer periphery toward the center of the end plate 6, and an opening 16 in the concave portion 15 that communicates the inside and outside of the concave portion 15 with the central portion of the end plate 6. It is composed of: In this case, the recess 15 is an end plate 6 made of iron plate.
The extending direction of the recessed portion 15 is oblique to the radial direction of the end plate 6, as can be seen from FIG. Further, although not shown, the rear end plate 7 of the reel 5 is also formed with a heat dissipation port 14 having the same structure as the front end plate 6.

In the case of the above structure, when using it, connect the plug 13 of the cord 12 wound around the reel 5 to a power outlet (not shown), and connect the plug of the cord of the load (not shown) to the outlet 9. When connected, the load is operated, and the folded cord 12 generates heat during this operation. Here, even if the cord 12 is wound around the reel 5 to the extent that the opening end 15a of the recess 15 in the heat dissipation port 14 is covered as shown in FIG. A space 17 is always ensured between them, and this space 17 is the opening 16.
Since the cord 12 always faces the outside through the space 17 and the opening 16, the heat of the cord 12 can always be efficiently dissipated to the outside. Furthermore, in this case, a ventilation path is secured in the heat radiation port 14 by the outer peripheral side portion 15b of the recess 15, the space 17, and the opening 16, and the heat radiation performance can be further improved by allowing air to flow through this ventilation path. can.
Further, since the recess 15 faces the cord 12 and the size of the opening surface of the heat dissipation port 14 relative to the cord 12 can be secured by the recess 15, there is no need to make the size of the opening 16 particularly large. Therefore, a decrease in strength of the end plates 6 and 7 can be suppressed compared to the case where the size of the opening of the heat radiation port is increased.

In particular, according to the above embodiment, although the opening 16 is formed in the end plate 6 (and the end plate 7), the recess 15 is
are formed on the end plates 6, 7 by stamping, the shape of the concave portion 15 can strengthen the end plates 6, 7. A decrease in strength can be more reliably suppressed. Furthermore, by forming the extending direction of the recess 15 obliquely with respect to the radial direction of the end plates 6 and 7,
In addition to improving the appearance, the recess 15
There is an advantage that the length dimension can be ensured larger than when the extending direction of the end plates 6 and 7 is the radial direction of the end plates 6 and 7.

The present invention is not limited to the embodiments described above and shown in the drawings; for example, the specific shape of the recess 15 of the heat dissipation port 14 and the specific position of the opening 16 may be changed within the scope of the invention. It can be implemented with appropriate modifications within the scope of the invention.

[Effects of the invention] As is clear from the above description, the present invention has a heat dissipation port provided on the outer periphery of the end plate of the reel.
A recess formed in the end plate so as to bulge from the inside to the outside and extend from the outer periphery of the end plate toward the center, and an opening formed in the recess so as to communicate between the inside and outside of the recess. Compared to the conventional configuration in which the heat dissipation port was simply configured with an opening in the end plate, the heat dissipation performance from the heat dissipation port can be improved. This has an excellent effect of being able to achieve this while suppressing deterioration.
