Description

[Detailed description of the invention] This invention relates to a louver assembly structure in which louver blades are stacked and assembled into a sash frame of a rain door or the like.

In general, a louver such as a rain door or a hinged door has 10 louver blades as shown in Figures 1 and 2 A and B.
The vertical frame 1 on both sides that makes up the frame of the louver is
1 with a screw 12 and stacked one after another, a sealing material 13 or the like is secured to the head of the screw 12 and assembled.

However, in the conventional structure described above, sealing the screws 12 that fixed the ratchet blades 10 to the sash vertical frame 11 took time and effort, and there were problems in workability. In addition, the sealing material on the screw head easily breaks, and if it is damaged, rainwater can enter the vertical frame of the sash through the fixed part of the screw and seep into the room, or corrode the base material of the frame. .

This idea was made in order to solve the above-mentioned drawbacks of the conventional structure, and the louver blade is assembled using splints that constitute the louver vertical frame at both ends of the louver blade, and the louver vertical frame to which the louver blade is attached is used. This provides an assembly structure of a louver which is assembled by fitting the whole sash into a vertical frame.

Hereinafter, embodiments of this invention will be explained in detail based on FIGS. 3 to 6. FIG. 3 is an exploded perspective view of the louver according to this invention before assembly.
1 is a louver blade, 2 is a sash vertical frame, and 3 is a louver vertical frame to which the louver blade 1 is fixed and fitted to the sash vertical frame 2, each of which is molded from an aluminum extrusion material.

The louver blade 1 is formed from an extruded material such as aluminum, and has screw holes 1a and the like provided at appropriate locations.

The louver vertical frame 3 is fixed to both ends of the louver blade 1 with screws 4, etc., and this louver vertical frame 3 has a width that fits into the square groove 2a of the sash vertical frame 2. However, on the opposite side to which the louver blade 1 is fixed, a square-shaped engagement groove 3a is integrally formed.

Further, in the square groove 2a of the sash vertical frame 2 into which the louver vertical frame 3 is fitted, a square engaging portion 2b is integrally formed at a position where the square engaging groove 3a of the louver vertical frame 3 is engaged. It is formed as follows.

Incidentally, mounting holes 3b for screws 4 are bored at appropriate positions in the vertical louver frame 3 to which the louver blade 1 is fixed.

When assembling the louver blades 1 formed as described above to the sash vertical frame 2, first, as shown in FIGS. A louver subassembly 5 is constructed by fixing it to the louver vertical frames 3, 3 with screws 4.

Next, assemble the left and right sash vertical frames 2, 2 and the lower horizontal frame 6, and with the upper horizontal frame 7 removed, attach the louver subassembly 5 to which the louver blades 1 are fixed to the sash vertical frames on both sides. Fits into 2,2. At this time, the square-shaped engaging portion 2b provided in the square-shaped groove 2a of the vertical frames 2, 2
The louver sub-assembly 5 is fitted in such a manner that the square-shaped engagement grooves 3a provided in the louver vertical frames 3, 3 are engaged with each other. Thereafter, the horizontal frame 7 is assembled from the upper part of the left and right vertical frames 2, 2 to assemble the louver.

As explained above in detail, the assembly structure of the louver according to this invention has simple components, and each component is molded from extruded materials such as aluminum sash, so no special machining is required. Can be manufactured cheaply.

In addition, the louver is assembled by fitting the louver sub-assembly, in which the louver blades are fixed to the louver vertical frames at both ends in advance, between the sash vertical frames, which simplifies the assembly process and reduces assembly man-hours. In addition, there is no damage such as the louver blade coming off after assembly.

Furthermore, the vertical louver frame to which the louver blades are fixed is not exposed to the outside of the sash vertical frame, and there is no place for rainwater to enter from the outside, so it has good corrosion resistance, and the high assembly strength improves durability. It has the following effects.
