Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a cord reel device for an electric iron that winds and holds a power cord so that it can be freely drawn out.

(Technical background of the invention and its problems) Fig. 4 shows the general structure of an electric iron with a cord reel, in which 1 is an iron main body, and a reel cover 2 is provided on the rear end surface of this iron main body 1. .Iron body 1
A support shaft 3 is integrally provided at the center of the rear end surface, and a connection shaft 4 is integrally provided at the center of the inner surface of the reel cover 2. It is connected by fitting into the inner hole. A cord reel 5 and a spiral spring 6 are provided around the outer circumferences of the support shaft 3 and the connection shaft 4, and a power cord 7 is wound around the cord reel 5. The spring spring 6 has one end fixed to the connecting shaft 4 and the other end fixed to the cord reel 5, and the spring spring 6 elastically urges the cord reel 5 in one rotation direction, that is, in the direction in which the power cord 7 is wound. ing. The winding end of the power cord 7 is led out to the outside through an outlet 8 formed at the upper end of the reel cover 2, and a plug 9 is attached to this outlet end.

By pulling out the power cord 7 against the spiral spring 6, the length of the power cord 7 can be set to any length necessary for use. Note that a one-way clutch mechanism (not shown) is provided between the reel cover 2 and the cord reel 5, and this one-way clutch mechanism prevents the cord reel 5 from reversing, and this one-way clutch mechanism is not shown. By performing a release operation via the operation button, the power cord 7 can be wound onto the cord reel 5 again by the biasing force of the spring spring 6 and stored compactly within the reel cover 2.

To describe the procedure for assembling such an electric iron with a cord reel, first attach the power cord 7 to the cord reel 5.
Then, the cord reel 5 is assembled with the spring spring 6 into the connecting shaft 4, and in this state, the cord reel 5 is rotated several times against the spring spring 6, so that the power cord 7 is always under an appropriate tension. Preliminary torque is applied to the reel 5, and the end of the power cord 7 is passed through the outlet 8 and the plug 9 is hooked to its edge. Thereafter, the reel cover 2 is placed against the rear end surface of the iron body 1 and fixed with screws or the like.

By the way, when the power cord 7 is wound around the cord reel 5, if the power cord 7 is left as it is, it will loosen due to its own elasticity and come off, so conventionally, as shown in FIG. A rubber band a is wrapped around the outer periphery of the power cord 7, and the rubber band a prevents the power cord 7 from becoming unraveled.

However, with this method of wrapping the rubber band a around the outer circumference of the cord reel 5 one by one, not only does the work efficiency drop significantly, but the rubber band a easily slips off, making it impossible to achieve the intended purpose. There are many things. Also,
Cord reel 5 and mainspring spring 6 are attached to reel cover 2
When incorporating it into the inner surface of the cord reel 5 to give preliminary torque to the cord reel 5, as shown in FIG. However, the peripheral edge of the flange 5a is located close to the peripheral wall 2a of the cover 2, and therefore 1! There was a problem in that the terminal part of the source cord 7 became a hindrance, making it difficult to rotate the cord reel 5 smoothly.

[Purpose of the invention]

This invention has been made with attention to these points, and its purpose is to easily and reliably lock the power cord to the cord reel and to facilitate the assembly of the cord reel into the reel cover. To provide a cord reel device for an electric iron, which can smoothly rotate the cord reel when applying preliminary torque to the cord reel.

[Summary of the invention]

That is, in the present invention, a locking portion capable of locking the winding end portion of the power cord is formed in the periphery of the flange of the cord reel, and the power cord is locked in the locking portion as necessary. It is designed so that it can be stored.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

A locking portion 10 is cut out in the periphery of one flange 5a of the cord reel 5. As shown in FIG. This locking portion 10 has a shape that substantially corresponds to the cross-sectional shape of the power cord 7. That is, in this embodiment, since the power cord 7 has a flat cross-sectional shape, the locking portion 1 is designed to correspond to the flat shape.
0 is formed into an oval shape. This elliptical locking part 10 is arranged so that its major axis is along the periphery of the flange 5a, and is opened to the outer periphery of the flange 5a through an opening 10a that continues in the middle, and the width of the opening 10a is is slightly narrower than the thickness t of the power cord 7.

Thus, during assembly, after winding the power cord 7 around the cord reel 5, the end portion of the power cord 7 is inserted into the locking portion 10 and locked.

At this time, as shown in FIG. 3(a), the power cord 7 is arranged so that the surface of the thickness t faces the open part 10a of the locking part 10, and in this state, the power cord 7 is inserted into the open part 10a. Push it into. In response to this, the insulating coating on the outer periphery of the power cord 7 is elastically deformed and the power cord 7 enters the locking part 10, so that the power cord 7 is then moved as shown in FIG.
It is rotated by 90 degrees and placed so that its two-width surface faces the open portion 10a. This prevents the power cord 7 from coming off and locks it in a stable and reliable state.

In this way, the end of the power cord 7 is locked to the flange 5a via the locking part 10, the plug 9 is led out to the outer surface of the flange 5a, and then the cord reel 5 is attached to the reel cover 2 in the same manner as described above. The cord reel 5 is assembled and given a preliminary torque. At this time, the terminal part of the power cord 7 is connected to the locking part 1
0 and does not protrude from the periphery of the flange 5a in any way, so that the cord reel 5 can be rotated smoothly and preliminary torque can be efficiently applied.

After applying the preliminary torque, remove the end of the power cord 7 from the locking part 10 while maintaining that state, pass this end through the outlet 8 of the reel cover 2, and plug the plug 9.
is hung on the edge of the outlet 8. In this state, the reel cover 2 is placed against the rear end surface of the iron main body 1 and fixed with screws or the like in the same manner as described above, thereby completing the assembly.

Note that the locking portion is not limited to being provided at one location on the flange, but may be provided at multiple locations, for example, at four equally spaced locations around the periphery of the flange. By selecting the locking portion closest to the flange, the end of the power cord can be locked to the periphery of the flange more efficiently.

(Effects of the Invention) As explained above, according to the present invention, the end portion of the power cord can be easily and efficiently and reliably connected to the periphery of the flange without using any separate members such as rubber bands as in the past. Therefore, the workability of assembling the cord reel into the reel cover is greatly improved, and the cord reel can be rotated smoothly when applying preliminary torque to the cord reel.
