Description

[Detailed explanation of the idea] 〔Technical field〕 The present invention relates to the structure of a long louver door.

[Background technology]

Conventionally, long louver doors are constructed by providing grooves for attaching the louver crosspieces inside the left and right vertical stiles, inserting both ends of the louver crosspieces into these grooves, and joining the vertical stiles and horizontal stiles with dowels. However, in this configuration, the grooves are provided directly on the vertical stile, which not only causes variations in the mounting positions of the louver crosspieces, but also causes warping and bending. It was necessary to make the frame thicker or to use a material with a high Young's modulus, which also posed a problem in terms of price. Furthermore, since the vertical stile and the horizontal stile are joined only by dowels, there is a problem in that a strong joint structure cannot be obtained.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and its purpose is to eliminate variations in the mounting position of the louver crosspieces, to reinforce the vertical stile so that no warping or bending occurs, and to provide a vertical stile that is not warped or bent. To provide a long louver door structure in which the connection between a stile and a side stile is also strong.

[Disclosure of invention]

The structure of the long louver door of the present invention is a long louver rail mounting rail 1 having a plurality of louver rail mounting grooves 2.
and horizontal frame fixing pieces 3 are extended from the ends at approximately right angles to the sides, this louver bar mounting rail 1 is fixed into recesses 7 provided on the inner surfaces of the left and right vertical frames 4, both ends of the louver bars 5 are inserted into the louver bar mounting grooves 2, and the horizontal frame fixing pieces 3 are fixed into recesses 8 provided on the inner surfaces of the horizontal frames 6, and with this configuration the above object is achieved. That is, since the louver bars 5 are mounted via the louver bar mounting rails 1, there is no variation in the mounting position of the louver bars 5, and since the vertical frames 4 are reinforced by the louver bar mounting rails 1, there is no warping even if a vertical frame 4 made of a thin material with a small Young's modulus is used.
No bending occurs, and furthermore, since the vertical frame 4 and the horizontal frame 6 are joined by the louver rail mounting rail 1, a strong joint structure is obtained. Moreover, since the louver rail mounting rail 1 is fixed in a recess 7 provided on the inner surface of the vertical frame 4 and the horizontal frame fixing piece 3 is fixed in a recess 8 provided on the inner surface of the horizontal frame 6, the louver rail mounting rail 1 is difficult to see from the outside, giving the exterior a neat appearance.

The present invention will be described below based on embodiments shown in the accompanying drawings.

The long louver crosspiece mounting rail 1 is made of metal, and is provided with a plurality of louver crosspiece mounting grooves 2, and horizontal stile fixing pieces 3 extend from both ends at right angles toward the sides. has been done. The louver crosspiece mounting groove 2 is connected to the louver crosspiece mounting rail 1 as shown in FIG.
They are provided at equal intervals along the longitudinal direction and inclined at equal angles. This louver crosspiece mounting rail 1 is fixed to the inner surfaces of the left and right vertical frames 4, and both ends 5b of the louver crosspiece 5 are inserted into the louver crosspiece mounting grooves 2 as shown in FIG. is fixed to the inner surface of the horizontal stile 6. Recesses 7 and 8 are provided in the inner surfaces of the vertical stile 4 and the horizontal stile 6, respectively, and the louver crosspiece mounting rail 1 and the horizontal stile fixing piece 3 are fixed in a buried state. As shown in FIG. 3, the thickness and width of both ends 5b of the louver crosspiece 5 are
The edge of the louver crosspiece mounting groove 2 is made slightly smaller than the thickness of the groove 2 so that the edge of the groove 2 is not visible from the outside. In the figure, 9 is a dowel that fits into the dowel hole of the horizontal stile 6, and 10 is a through hole for a screw nail.

[Effect of idea]

In the case of this invention, since the louver crosspieces are attached via the louver crosspiece mounting rails, there is no variation in the mounting position of the louver crosspieces, and since the vertical frame is reinforced by the louver crosspiece mounting rails, it can be made thinner. Even if the vertical stile is made of a material with a small Young's modulus, it will not warp or bend.Furthermore, the vertical stile and horizontal stile are connected by the louver crosspiece mounting rail, resulting in a strong joint structure. In addition, the louver frame mounting rail is fixed in the recess provided on the inner surface of the vertical stile, and the horizontal stile fixing piece is fixed in the recess provided on the inner surface of the horizontal stile. The rail for mounting the crosspiece can be made difficult to see from the outside, and the appearance can be made clean.

[Brief explanation of the drawing]

FIG. 1 is a schematic overall diagram showing an embodiment of the present invention;
Figures 2 and 3 are partially exploded perspective views of the same as above, in which 1 is a rail for attaching a louver crosspiece, 2 is a groove for attaching a louver crosspiece, 3 is a piece for fixing a horizontal stile, 4 is a vertical stile, and 5 is a louver. 6 is a horizontal stile, and 7 and 8 are recesses.
