Description

[Detailed description of the invention] Industrial applications This invention relates to an iron.

Conventional configurations and their problems There are two types of cord attachment methods for conventional irons: a free-turn type in which the direction of the cord is freely changed, and a fixed type in which the direction of the cord is always constant. If you install a fixed cord with a mounting structure or a free-turn cord with a fixed cord attachment structure, the following disadvantages will occur. It has the disadvantage that it cannot be installed selectively.

In other words, in the case of a fixed type, the cheapest option is to provide a protrusion on the cover that covers the terminal, insert the branch part of the cord into the groove provided on the handle side, and use the protrusion to insert the branch part of the cord into the groove provided on the handle side. This is a press fixing method, but when a movable cord is fixed using this method, when the cord is bent, concentrated stress is applied to the protrusion pressing part of the cord, and the protrusion pressing part is subjected to a considerably large force due to the protrusion. Since the cord is pressed at the position where it is pressed, there is a disadvantage that the cord is broken at the position where it is pressed.

On the other hand, when fixing a movable cord, in order to prevent the cord from breaking when the cord is bent as described above, another fixing device is used at the part where the cord is less likely to break when bent, that is, at the non-branching part of the cord. A method is used in which the cord is fixed to the iron body. When fixing a fixed cord using this method,
Since the cord is a fixed type, it is necessary to use a cord fixing device as a separate component, although the cord itself hardly experiences any bending force, resulting in a disadvantage of high cost.

Purpose of the Invention The purpose of the present invention is to make it possible to selectively attach a free-turn type cord and a fixed type cord using a common iron body, to prevent cord breakage when a free-turn type cord is attached, and to fix the cord in a fixed manner. To provide an iron in which a cord fixing device can be omitted when a cord is attached.

Structure of the Invention An iron having a main body that can be used in both an iron with a free-turn type cord protector at the rear of the main body and an iron with a cord fixing cord tube on the side of the main body, and a terminal chamber opened to the rear is formed at the rear. a cover that closes the rear opening of the terminal chamber; a cord that passes through the cover and connects the tip of the branched portion to a pair of terminals spaced apart from each other in the terminal chamber; a first groove provided in the vicinity of the attachment part of the free-turn type cord protector and through which the cord passes; a cord fixing device attachment part provided in the vicinity of the first groove; and the first groove in the terminal interior wall.
A second groove is provided between the groove and the pair of terminals and widens toward each terminal, and the branch part of the cord is press-fitted and fixed by a projection protruding from the inner surface of the cover.

As a result, the free-turn type cord is fixed by passing the cord through the first groove and attaching the cord fixing device to the cord fixing device attachment portion, and the cord branching portion inserted into the second groove protrudes from the back side of the cover. The fixed cord is fixed by press-fitting it with the provided protrusion.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 to 4. Figures 1 and 2 show the mounting structure of the free-turn type cord, and Figures 3 and 4 show the mounting structure of the free-turn type cord.
The figure shows the mounting structure of the fixed cord. In each figure, 1 is an iron main body which also serves as a handle, and a terminal chamber 2 which is open to the rear is formed at the rear thereof. A pair of dowels 3, 3 are placed on the inner wall of this terminal room 2.
are protruded in parallel to form a first groove 4 for inserting the non-branched part of the cord between both dowels 3, 3, and both dowels 3,
3 are formed with screw holes 5, 5 (FIG. 3) for attaching a cord fixing device, and these first grooves 4 and screw holes 5 constitute a cord fixing device attaching portion. Further, a second groove 6 for inserting a bifurcated cord branch is formed below the first groove 4, and a pair of terminals 7, 7 are provided below the exit side of the second groove 6. Place. 8 is a screw hole for attaching the cover, and 9 is a protrusion for preventing the cord from slipping.

In FIGS. 1 and 2, a cover 10 is attached to the rear part of the iron main body 1 by fastening a screw 11 to a screw hole 8, and closes the rear opening of the terminal chamber 2. 12 is code 1
This cord protector is rotatably attached to the upper part of the cover 10 so that the direction in which the cord 3 is led out can be changed.

In FIGS. 3 and 4, 14 is another cover, and a protrusion 15 is provided on the back surface of the cover at a position corresponding to the second groove 6 for inserting the cord branch part, and the iron body 1 screw to the rear part of the body through the screw hole 8. In this case, the protrusion 15 is the cover 1
When the cord 13' is screwed to the iron body 1, the branch part 13a' of the cord 13' can be pressed and fixed into the second groove 6. 16 is a cord tube for pulling the cord 13' out of the cover 14.

The installation procedure for the free-turn type cord 13 is as shown in FIGS. 1 and 2. With the cover 10 removed, the cord 13 is passed through the cord protector 12, and the branched end of the cord 13 is connected to the terminal 7 with the screw 17.
and connect the cord branch part 13a to the second groove 6.
By passing the cord non-branching part 13b into the other first groove 4 and fixing the cord fixture 18 to the boss 3 with the screw 19, the cord non-branching part 13b is fixed to the boss 3 with the cord fixture 18. Iron body 1
Finally, the cover 10 is attached to the iron body 1 with screws 11. On the other hand, the installation procedure for the fixed cord 13' is shown in FIGS. 3 and 4 with the cover 14 removed.
3' through the cord tube 16, and connect the branch end of the cord 13' to the terminal 7 with the screw 17.
By inserting the cord branching part 13a' into the groove 6, passing the cord non-branching part 13b' into the first groove 4, and screwing the cover 14 to the iron main body 1, a protrusion is formed on the back surface of the cover 14. protrusion 1
5, the cord branch 13a' is pressed and fixed into the second groove 6.

In this way, by using the common iron body 1, the free-turn type cord 13 and the fixed type cord 1 can be used.
3' can be selectively attached. Moreover,
In the case of the free-turn type, since the non-branched part 13b of the cord 13 is fixed to the iron body 1 by the cord fixing device 18, even if bending force is generated on the cord 13 by changing the direction in which the cord 13 is led out, the cord The non-branched portion 13b can sufficiently withstand the bending force, and breakage of the cord 13 can be prevented. In addition, in the case of a fixed type, the cover 14
The cord branching part 1 is
3a' can be press-fitted and fixed into the second groove 6, and unlike the free-turn type, no bending force is generated on the cord 13', so that the cord non-branching part 13b' can be fixed by the cord fixing device 18 (Fig. 1). Since there is no need to fix the cord, the cord fixing device 18 can be omitted and the manufacturing cost can be reduced accordingly.

Effects of the Invention According to the present invention, it is possible to selectively attach a free-turn type cord and a fixed type cord using a common iron body, and when a free-turn type cord is attached, it is possible to prevent the cord from breaking and to fix the cord. When the type cord is attached, the effect that the cord fixing device can be omitted can be obtained.
