Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a shutter box structure in which a shutter material is wound around a drum provided in a storage box and moves up and down.

[Conventional technology]

Such a shutter is housed in a state of being wound around the outer upper part of the sash, etc., but the structural wall of the housing box is constructed by combining an appropriate number of metal plate materials. Therefore, this assembly is easy to assemble,
At the same time, it is required to be strong against internal pressure and external pressure caused by wind.

FIG. 8 shows the connection structure of the conventional example, in which the two plate members 4 and 5 are provided with concave and convex fitting structures 6 and 7, respectively. It is designed to be fitted with a plug-in type.

[Problems to be solved by the device]

However, with such a configuration, a space for inserting work is required to be at least twice the dimension of the finished product in the strip direction, and when it becomes long, it is caused by the bending or bending of the plate materials 4, 5, and the like. There is a problem that the resistance increases and you cannot slide smoothly. Further, in order to simplify the insertion work, it is conceivable to increase the gap between the fitting structures 6 and 7, but if this is done, there will be play in the fitting and the strength of the joint will be insufficient.

Fig. 9 shows the improvement of this, and although the fitting structures 6 and 7 of unevenness are the same, it is made into a shape that can be butted and joined from the left and right, and bolts are used between the joints. It is fixed through the etc. In this case, a space for assembling is not necessary, but holes and screw holes must be formed in the joint portion, and fasteners such as bolts, nuts or rivets are required. Furthermore, during bolting work, there is a risk of hitting the other party and damaging it.

The present invention solves such a problem, and an object thereof is to reveal a shutter having a coupling structure that is easily coupled and is firmly coupled.

[Means for solving the problem]

That is, this device: A shutter material storage box is constructed by using two mating structures that are fitted to each other and plate members formed at the ends are combined, and one of the two mating structures is A straight wall and a bent vertical wall having a horizontal part in the middle are hung from one plate to have a groove opening downward between the two, and the other plate has an upright wall and an outward curved wall from the other plate. And have a groove that opens upward between them, first tilt one plate and insert the outer curved wall of the other plate into that groove, and then rotate one plate. Then, straighten the other plate and make the straight wall contact the groove of the outer curved wall of the other plate, and at the same time the tip of the outer curved wall rests on the horizontal part of the bent vertical wall. Bend downwards at the bottom of a curved or curved vertical wall Shutter box structure provided with engagement pieces straight to one of the plate material and the other plate material, characterized in that disables bend detached.

. A box structure for a shutter, characterized in that, instead of the engaging piece described above, another member is inserted between the outward curved wall and the bent vertical wall to make one plate member and the other plate member incapable of being bent and separated. .

Is provided.

[Action]

By adopting the above means, both fitting structures can be joined simply by fitting, rotating and bending (extending). Further, since the engaging pieces are connected to each other in a state of being engaged with each other, a tight connection can be made without folding back or backlash.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 7 is a sectional view of the shutter. The shutter material 1 is wound up and down by a drum 3 installed in a storage box 2 provided at the upper part of the mounting portion. Then, the box 2 is assembled by a configuration in which the metal plate members 4 and 5 divided into appropriate sizes are appropriately combined as described above.

1 to 3 show this combined structure,
It is the same as the conventional example that the mating structures (ends) of both plate materials 4 and 5 are provided with concave and convex fitting structures 6 and 7, but the following structure is different from the insertion type and the butt type. Take That is, one has a straight wall 6a and a bent vertical wall 6b having a horizontal portion in the middle of one plate member 4 and has a groove 6c opened downward between the two 6a, 6b. The upright wall 7a and the outward curved wall 7b are hung from the other plate member 5 to have a groove portion 7c opened upward between the two members 7a, 7b, and the fitting operation is performed first. If the outer curved wall 7b of the other plate member 5 is fitted into the groove 6c of the plate member 4 tilted at a certain angle, both plate members 4 and 5 can be fitted in a fitting manner (Fig. 1), and then one of the plate members 4 and 5 can be fitted. When the plate member 4 is rotated, both plate members 4 and 5 are straightened in the connected state (Fig. 2), and finally, the engagement is provided by bending the lower end of the outward curved wall 7b downward. When the piece 7d is straightened, it extends to the bending vertical wall 6b of the other side, restricts both plates from trying to bend and separate, and is completely fixed. Than it is so (Figure 3). In addition to these, the engaging piece shown in FIG.
6a and 7a formed on both plate members 4 and 5 and another member 8 for fitting instead of these engaging pieces 6a and 7a shown in FIG. 5 between the outward curved wall 7b and the bent vertical wall 6b. It is conceivable that the sealing member 9 is inserted into the vertical wall 6a and the upright wall 7a shown in FIG.

[Effect of device]

As described above, since the present invention has been described above, the following effects can be expected.

i) Since both fitting structures 6 and 7 formed at the ends of both plate members 4 and 5 can be joined simply by fitting and turning, a large space is not needed for assembling, and the joining operation is also unnecessary. It's quick and easy.

ii) Since both fitting structures 6 and 7 are fitted and rotated, one of the engaging pieces 7a and the like is engaged with the other to restrict reverse rotation, so Even if a force is applied from the direction, it will not bend at this part nor will it separate.

iii) Since fasteners such as bolts and rivets are not used, hole drilling and the like associated therewith are unnecessary, and the machining cost is reduced.
