Description

[Detailed Description of the Invention] The present invention relates to a structure in which a plurality of plate-shaped parts are overlapped and fastened together.

Conventionally, in order to overlap and fasten multiple plate-like parts together,
Methods such as rivets and welding have been used, but these operations are difficult in narrow spaces.

For example, as shown in FIG. 5, in order to assemble the louver frame 3 in which the horizontal louvers 1 and vertical louvers 2 of the hot air blowing heater are assembled to the front panel 4, the louver frame 3 and the front panel 4 must be fitted with flanges, respectively. 5, 6 and 7, 8 are provided, and their flanges are overlapped with each other and fastened with rivets 9 and 10. The riveting work on the upper part of the louver frame 3 is performed using the shovel rivet tool base 11 and the front panel 4. Therefore, the protruding length of the flanges 5 and 7 must be increased, and as a result, a relatively large gap is created at the upper part of the louver frame 3. 13 has occurred.

Therefore, an object of the present invention is to provide a structure in which a plurality of plate-shaped parts can be overlapped and fastened together without the need for special tools instead of using rivets, welding, or the like.

Furthermore, the present invention aims to achieve the above object with a simple structure.

Another object of the present invention is to provide a plate fixing structure that can be easily fixed but cannot be easily removed after fixing.

According to the present invention, the other end is connected to the other end so that a plurality of plates to be fixed can be elastically sandwiched between two opposing substantially flat plate parts whose one end is connected to each other by the coupling part. By making cuts in each of the plate parts, opposing claws having free ends are provided on the joint side of the plate parts, and the claws are slightly bent in a direction toward each other, and The free ends of the plate parts include a plate fixing fitting which is integrally provided with guide parts that are gently bent in the direction of moving away from each other, and the plate to be fixed is provided with a hole for receiving the claw, and the plate fixing fitting is provided with a hole for receiving the claw. There is provided a plate material fixing structure characterized in that the plates to be fixed are fixed to each other by being attached to the plurality of mutually overlapping fixed opposing plates, and by fitting the claws into the holes, thereby fixing the plates to be fixed to each other. It will be done.

The present invention will be described below using examples with reference to the drawings.

First, FIGS. 1 and 2 show an embodiment of the plate fixing fitting used in the present invention.

This plate material fixing fitting 20 is made of carbon tool steel (SK-5), for example.
It is made by press-cutting or bending a plate, and includes two substantially flat plate portions 21 and 21 facing each other, and a joint portion 22 that connects these plate portions at one end. have.

By making cuts in each of the plate parts 21, 21, opposed claws 23.2 having free ends on the joint part 22 side are formed.
3 are provided respectively, and the claws 23 and 23 are bent slightly in the direction toward each other.

Further, the ends of the plate portions 21.21 opposite to the coupling portions 22, that is, the portions near the free ends, are integrally provided with guide portions 26 that are gently bent in the direction away from each other.

Now, in FIG. 2, the boundary parts of the plate parts 21, 21 and the guide part 26 are in contact with each other, but this can be separated from each other, and moreover, the plate parts 21 and 21 become almost parallel to each other. The claws 23, 23 are made so that they are in contact with each other even when they are separated.

Now, FIG. 3 shows an example structure in which the flange 5 of the louver frame 3 and the flange 7 of the front panel 4 are fastened together according to the present invention.

That is, holes 24. are formed in opposing positions of the flanges 5 and 7.
24 respectively, and the plate material fixing fittings 20 shown in FIGS.
, 7 and push it in so that the flanges 5 and 7 are received between the plate parts 21 and 21.

In other words, the guide section 26 guides the start of this mounting operation.

Note that when the plate material fixing fitting 20 is installed at its deepest position, the claw 2
The dimensions of each part are designed so that 3.23 fits into the hole 24.24.

Once the claw 23 is fitted into the hole 24, even if a pushing force is applied to the tip of the guide portion 26 from the outside with a finger or the like, that force will hardly be transmitted to the claw 23, so that the claw 23 will not come off from the hole 24, and if the guide part 26 is pushed open, the claw 23 will not come off.
Since the parts located on both sides of the
Even in this case, the tip of the claw 23 does not come out of the hole 24.

Therefore, the fixation is ensured without being easily released.

In this manner, in the state shown in FIG. 3, the claw 23 fits into the hole 24, thereby trapping the tip portions of the flanges 5, 7 between the joint portion 22 and the tip of the claw 23, thereby causing
This prevents misalignment.

Further, at this time, by making the hole 24 have such a shape and size that it can just receive the claw 23, displacement in the left-right direction can be prevented.

However, when assembling the louver frame 3 of the warm air heater to the front panel 4 as in this embodiment, as shown in FIG. It is sufficient to use the louver frame 3 to prevent displacement only in the front-rear direction 25, and displacement in the left-right direction can be prevented by collision of the flanges at the left and right portions of the louver frame 3.

In the structure in which the louver frame 3 is assembled to the front panel 4 in this manner, the gaps at the interface can be made uniform, and therefore a warm air blowing type heater with an excellent appearance can be provided.

As explained above using the embodiments, according to the present invention, it is possible to overlap and fasten a plurality of plates to be fixed to each other.
It can be easily installed even in narrow spaces without using any special tools, and the structure is simple. It has the advantage of being securely fixed.
