Description

[Detailed description of the invention] Purpose of the invention (industrial application field) This invention relates to fittings such as shoji screens, doors, sliding doors, etc., in which a pleated screen is stretched within the frame.

(Prior art) Conventional fittings of this type have the disadvantage that the screen sags due to its own weight, and the opening angle of each pleat piece on the upper side is wider than that on the lower side, spoiling the overall aesthetic appearance. It was hot.

(Problems to be Solved by the Invention) This invention was made in view of the above-mentioned conventional technology, and aims to improve the appearance by positioning each pleat piece.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, this invention takes a measure of providing a holding member for contacting and holding each pleat piece inside the vertical stile.

(Function) With the above solution, the angle of the bent end of each pleat piece is kept substantially constant.

(Example) An example in which this invention is applied to a sliding door will be described below with reference to FIGS. 1 to 5.

As shown in FIG. 1, the frame 2 of the sliding door 1 is composed of a pair of left and right vertical frames 3, and an upper frame 4, a lower frame 5, and a middle frame 6 as horizontal frames. Therefore, the sliding door frame 2 is divided into an upper frame part 7 and a lower frame part 8 by the middle crosspiece 6, and a pleated screen 15, which will be described later, is stretched inside each part. As shown in FIG. 2, fitting grooves 5a are provided on the lower surface of the upper crosspiece 4, on both upper and lower surfaces of the middle crosspiece 6, and on the upper surface of the lower crosspiece 5, and on the left and right sides of each crosspiece 4, 5, and 6. An insertion hole 6a is formed in the vertical direction through which a reinforcing member 9 in the shape of a thin round rod made of synthetic resin or the like is inserted.

Inner crosspieces 10 made of metal such as aluminum or synthetic resin are fitted and fixed in each of the fitting grooves 5a. This inner crosspiece 10 includes a pair of left and right webs 11, and a pair of upper and lower ribs 12a, 12b bent inward from both upper and lower ends of the webs 11.
A joint 1 integrally constructed between the left and right webs 11
3, and the coupling portion 13 is provided with an insertion hole 13a that faces the insertion hole 6a.
Further, a groove-shaped support portion 14 is formed between the coupling portion 13 and one rib 12a. The inner crosspiece 10 is fitted into each fitting groove 5a so that the support portions 14 are vertically opposed to each other in both the upper and lower frame portions 7 and 8, respectively. The reinforcing member 9 is attached to each inner crosspiece 1.
0, and its upper and lower ends are fixed in the insertion holes 13a of the upper and lower bars 4 and 5 by nuts (not shown).

Inside the upper and lower frames 7 and 8 are a large number of pleat pieces 17 extending in the left-right direction and formed by folding sheets, cloth, non-woven fabric, paper, synthetic resin, etc., each having a predetermined rigidity, into the same width. A zigzag pleated screen 15 is arranged. The end pleat pieces 15a at the upper and lower ends of the screen 15 are supported by the supporting portion 14 so as to be movable in the lateral direction, and the left and right ends of the screen 15 are formed into accommodation grooves 1 formed on the inner surfaces of both vertical frames 3.
It is loosely fitted in 6. In addition, small holes 17a are provided in the left and right sides of each pleat piece 17, through which the reinforcing member 9 is inserted with a margin.

On the other hand, square bar-shaped wooden retaining bars 18 are respectively fitted into the front sides of both housing grooves 16, and both upper and lower end surfaces of both retaining bars 18 are brought into contact with the lower and upper surfaces of each of the inner bars 10. This prevents each inner crosspiece 10 from falling off from each of the fitting grooves 5a. A holding member 19 made of an elastic material such as rubber or sponge is attached to the rear side of the both clasp 18. and,
The front bent end of each pleat piece 17 of the screen 15 is in contact with the holding member 19 in a slightly bitten state.

Therefore, according to the configuration of this embodiment, even if a force in the drooping direction due to the weight of the screen 15 acts on each pleat piece 17 on the upper side side, the bent end of each pleat piece 17 is held by the holding member 19. Therefore, the opening angle of each pleat piece 17 is maintained at a predetermined position. Therefore, the pleat lines of the screen 15 extend at equal intervals, and the appearance can be made beautiful for a long period of time.

By the way, as shown by the solid line and chain line in Fig. 3, the vertical length of the pleats depends on the height of the fittings.
It is determined by the product of the pitch, which comes from the number of pleats and the opening angle. In this case, if the opening angle of each pleat piece 17 is changed according to the vertical length of the fittings, the front and rear widths of the screen 15 will accordingly have different dimensions as shown by B1 and B2 in the same figure. . However, according to the fittings of this embodiment, the retaining member 1 made of an elastic material is attached to the retaining member 18.
9, even if it is necessary to change the vertical dimensions of the screen 15, the holding member 19 can always be in contact with the bent end of each pleat piece 17 to securely hold it without damaging it. As a result, the above-mentioned effects can be obtained. Furthermore, since the reinforcing member 9 has a certain degree of rigidity, it acts as a resistance to the rearward movement of the screen 15 and has the function of holding the bent end so that it does not come off the holding member 19.

Note that this invention is not limited to the above-mentioned embodiments, and substantially the same effects can be achieved even if it is embodied in the following manner.
