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) Conventionally, in this type of fittings, as shown in FIG.
The inner crosspiece 42 is fitted and held in the fitting groove 44 of the horizontal crosspiece 43. However, in this structure, the screen 41 expands and contracts in the lateral direction, causing wrinkles and deteriorating the appearance. That is, the screen 41 deforms over time by repeatedly expanding and contracting due to changes in humidity and temperature. According to the conventional structure, the ends of the screen 41 are fixed to the inner crosspiece 42, so that the ends are prevented from expanding and contracting, while the middle portion can freely expand and contract. As a result, distortion of the paper concentrates in the area where the screen 41 and the inner crosspiece 42 are attached, causing problems such as spoiling the appearance and causing the screen 41 to peel off from the inner crosspiece 42 due to the strain. Furthermore, when the screen 41 is replaced, adhesive materials, adhesives, or resins such as staples remain on the inner rail 42, staining the inner rail 42.

(Problems to be solved by the invention) This invention was made in view of the above-mentioned conventional technology, and its purpose is to absorb the horizontal expansion and contraction of the screen, prevent its deformation, and provide long-term use. It is an object of the present invention to provide a new fitting that can maintain the aesthetic appearance of the screen and simplify the assembly work without using fixing means such as adhesives or staples.

Structure of the invention (means to solve the problem) In order to solve the above problem, this invention:
A support part for movably supporting the upper and lower ends of the screen in the horizontal direction is provided inside the horizontal frame, and a holding part made of an elastic material for contacting and holding the pleat pieces is provided inside the vertical stile. .

(Function) With the above solution, the screen can be stretched within the frame while allowing movement of both the upper and lower ends of the screen.

(Example) An example in which this invention is applied to a sliding door will be described below with reference to FIGS. 1 and 2.

As shown in FIG. 1, the frame 2 of the sliding door 1 is composed of a pair of vertical frames 3 on the left and right sides, 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.

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, a large number of pleat pieces 17 extending in the left-right direction are 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. Further, 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 rod-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 ends of each pleat piece 17 of the screen 15 are in contact with the holding member 19 in a slightly bitten state.

Now, in this embodiment, the support parts 14 are formed on the upper and lower inner bars 10, so that the screen 1
Since the end pleat pieces 15a of the screen 15 are movably supported, both the upper and lower ends of the screen 15 are not blocked by the inner crosspiece 10 against expansion and contraction that occurs over time, and are kept in the same state as the middle part. It can move freely laterally and maintain a good appearance. Furthermore, since the screen 15 can be assembled simply by inserting the end pleat pieces 15a into the support portion 14, the work can be easily carried out without using any fixing means such as adhesive or staples.

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