Description

[Detailed description of the invention] The present invention relates to an iron in which a cover is fixed to an iron base using a plate nut.

Figure 1 shows a conventional ironing cover mounting device. Reference numeral 1 indicates an ironing cover, and a handle part 2 is formed integrally with the cover on the top surface of the cover, and is made of heat-resistant synthetic resin or the like. There is.

This cover 1 is removably attached to the iron base 3 so as to cover a heat generating device, a control device, etc. (not shown) attached to the upper surface of the iron base 3.

To attach the cover 1 to the iron base 3, a screw hole 5 is provided at the upper end of the mounting bracket 4 installed on the inner upper surface of the iron base 3, the cover 1 is placed over the upper surface of the base 3, and the screw 6 is inserted.
is passed through the cover from the upper surface of a step 8 formed by a notch 7 provided on the front end surface of the cover 1, and is tightened and fixed.

On the other hand, on both sides of the upper rear end of the iron base 3, support fittings 9 in the form of an extended channel-shaped piece bent parallel to the other piece are screwed with screws 10, and on the lower surface of the rear end of the iron cover 1. , an embedded metal fitting 11 with a cut female thread is embedded together with the cover, and the base 3 and the cover 1 are integrated by tightening the embedded metal fitting 11 with a screw 12 from the lower surface of the protruding part of the support metal fitting 9. are combined.

If this kind of installation is a conventional device, it is difficult to make a mold due to the presence of the embedded metal fitting 11 when molding the iron cover 1, and it takes time and effort during the molding work, and it also takes time during the assembly work. However, the molded resin material flows into the embedded metal fitting during molding, and the threads of the screw thread are filled with the resin, which hinders assembly.

This idea was created based on these circumstances.
The purpose is to provide an iron that allows easy molding of an iron cover using a mold with a simple structure, allows easy and accurate assembly of the base and cover, and can be manufactured at low cost. That's true.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 2 and 3.

Since the same reference numerals as in the conventional configuration of FIG. 1 indicate the same parts, the explanation will be omitted, and only the different parts will be explained.

Reference numeral 13 denotes a hole for inserting a plate nut, and a plurality of holes 13 are provided on the rear surface of the iron cover 1 provided to cover the base, and have a depth in a direction parallel to the iron base 3 (two holes in the illustrated case). .

Further, on the lower end surface of the portion of the iron cover 1 in which the plate nut insertion hole 13 is provided, a screw through hole 14 which is perpendicular to the plate nut insertion hole 14 is opened on the lower surface.

Reference numeral 15 denotes a plate nut, which is made by punching a metal plate into a rectangular shape, and has an end thread hole 16 cut approximately in the center thereof, and the rear end surface of the cover 1 is inserted into and removed from the hole 13 for inserting the plate nut. It can be inserted freely and loosely.

Then, the end thread hole 16 and the screw through hole 14 match each other.
At this point, the outer end of the plate nut protrudes slightly outward.

It is formed to a similar size.

Then, attach the iron cover 1 to the top surface of the iron base 3, and attach the screw 6 to the mounting bracket 4 on the front part as in the case of FIG.
For the rear attachment, the lower opening of the screw through hole 14 of the iron cover 1 is brought into contact with the support plate, that is, the support fitting 9 attached to the base 3.

Insert the plate nut 15 into the plate nut insertion hole 13, and tighten the screw 1.
The iron cover 1 is attached to the iron base 3 by inserting the iron cover 7 through the lower surface of the support fitting 9, screwing it into the end thread hole 16 of the plate nut 15 through the screw through hole 14, and tightening it.

This operation can be easily screwed in by manipulating the end of the plate nut 15 with your fingers.

18 is a temperature adjustment knob, which is similar to 1 in Figure 3.
9 is a hole for taking out a terminal.

Reference numeral 20 designates a protrusion protruding from the cover 1 and having an end thread hole for attaching a rear lid plate of an iron (not shown).

Note that the present invention is not limited to the embodiments described above.

For example, in the embodiment described above, the support plate 9 is made of metal, but it may be made of a heat-resistant material other than metal.

Further, in the above embodiment, the hole for inserting the plate nut is provided parallel to the base 3, but it may be formed so as to be gradually inclined toward the back from the opening, for example, downwardly.

The point is that it should be provided approximately parallel to the base so that it can correspond to the support plate.

Further, in the above embodiment, a rectangular plate nut was used as an example, but a plate nut with a shape that can be inserted into and removed from the hole 13 for inserting the plate nut and cannot rotate within the hole 13 when the screw 7 is inserted is required. It may be of any other shape, if any.

As explained above, according to the present invention, it is not only easier to mold than the conventional method because no embedded metal fittings are used, but also the iron cover can be molded from two directions: the rear side of the iron cover and the bottom side that joins to the top surface of the base. A hole for inserting a plate nut and a screw through hole necessary for fastening the base and cover can be formed using a split die with a simple butt-type structure, making it extremely easy to mold the iron cover, and making it possible to form the plate nut easily. By simply inserting the product into the insertion hole, the product will be installed in a standby state, and the position can be adjusted arbitrarily by external operation, so even if there are variations in parts, assembly work can be done easily and accurately. Since the plate nut itself has a simple structure, it is possible to provide an iron that can be manufactured at low cost.

Further, according to the present invention, the tip of the screw inserted into the screw through hole through the hole provided in the support plate is simply screwed into the end thread hole of the plate nut inserted into the plate nut insertion hole. Since the installation is completed, there is no need to make special adjustments to the hole positions for screw insertion, and you can simply adjust the position of the plate nut where the end thread hole exists independently as described above. Since it can be done at any time, there is an advantage that screw insertion can be easily done without increasing the manufacturing precision of each part.
