Description

[Detailed Description of the Invention] The present invention relates to a novel structure of a top-hung sliding door that can be stored in a hollow wall.

Sliding doors have a structure where the inside of the wall, such as a partition wall, is hollow and the door plate is stored inside the hollow wall when opened.As the door length increases, if the door plate stored inside is made of wood, the wall thickness will increase. Unless you increase the height and the thickness of the door, you will not be able to do it due to insufficient rigidity. However, if we try to reduce the wall thickness to about 90 mm or less, it is actually difficult to install sliding doors with such a long door length. Furthermore, in conventional sliding doors of this type, the entire door panel is retracted when the sliding door is retracted, and a metal fitting is provided that can be pushed to the end of the door in order to pull out the door panel. Therefore, the structure was complicated and required a lot of man-hours to manufacture, and the door panels were not easy to draw out. In addition, the door board is made larger than the opening so that it can completely close the space between the door stop and the edge of the hollow wall, so it is not easy to install or remove it.

This invention allows the door to be stored in a thin wall even if the door is long, prevents fingers from getting stuck, makes it easy to pull out the door plate, and also makes it easier to construct a wall-mounted top-hung sliding door and install a sliding door. The purpose is to Its structural feature is that the width is slightly wider than the thickness of the door plate, and the width of the door plate is extended wider than the frontage between the door stopper 18 and the partition edge 6, which are housed in the hollow wall with the upper rail. The vertical stile 8 is provided as a separate member from the door panel body, and a decorative material 7 is provided on the parting edge 6 of the hollow wall 5 as a separate member. The vertical stile 8 is provided with a pull groove 9 that is continuous in the vertical direction.

The present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a partially cutaway perspective view of a wall storage type top-hung sliding door according to the present invention, and FIG. 2 is an enlarged cross-sectional view of the same partially omitted. FIG. 3 is a longitudinal sectional view of the same.

As is clear from these figures, the wall storage type top-hung sliding door according to the embodiment of the present invention has a width slightly wider than the thickness of the door plate 1, and has an upper rail 2 attached to the ceiling and a spacing member provided on the floor. Wall plates 4, 4 in close contact with 20
is provided, and a decorative material 7 with an inner corner notched is attached continuously from the ceiling surface to the floor surface on the parting edge 6 of the hollow wall 5 obtained as a result. The end vertical stile 8 of the door board 1 housed in the hollow wall 5 has a width sufficient to extend the main body of the door board 1 wider than the width between the door stop 18 and the parting edge 6, and It has a structure in which it can be fixed and detached from the butt end, and a pull groove 9 is continuously provided. The pull groove 9 may be provided continuously along the length of the door as shown in the figure, or may be provided continuously from the child's pull position to the adult's pull position.

The illustrated door panel 1 is made of steel plate or decorative plywood whose surface panels 10, 10 are resin-treated, and has an upper frame 12 and a lower frame 1.
3 are each made of an aluminum mold material or a synthetic resin mold material. And inside is a foamed polyurethane layer 1
1 or a paper core layer is formed. Therefore, even though the door length is large, it is lightweight and has high surface rigidity. A hanging door wheel 14 is provided on the upper part of the door plate, and has a structure in which the hanging door wheel 14 is rolled onto a hook-shaped hanging rail portion 15 provided on the upper rail 2. The lower frame 13 is provided with a guide groove 16, which fits into and slides on the protrusion 3 of the doorway. Note that the lower rail is not necessarily required.

The hollow wall 5 having the above-mentioned structure for storing the door plate 1 has the wall plates 4, 4 having an outer surface made of gypsum board and an inner surface made of a steel plate, and has a polyurethane foam layer 19 inside. is formed,
It has high rigidity, excellent sound insulation and heat insulation properties, and has sufficient functionality as a partition wall even though it is thin. The above-mentioned wall panels 4, 4 utilize the upper rail 2 as a gap-maintaining material, and are arranged oppositely to maintain a gap for housing the door panels. The same effect can also be obtained by using a decorative steel plate, decorative plywood, or base plywood for cloth pasting on the outside of the wallboard, and using a filling material such as foam or honeycomb on the inside.

Decorative material 7 for the edge of the hollow wall as in the above embodiment
lacks internal corners as described above. This fits into a vertically long fixed shape member 17 fixed to the parting edge 6. For this purpose, one edge of the fixed part has a locking gap with the parting edge 6, and the other edge has a hook. It is becoming a state. The decorative material 7 that fits into such a fixed shape member 17 is made by folding back one edge of a channel material with one corner cut out, and providing a protrusion on the other edge. This structure prevents jamming accidents, allows for removal and assembly, and makes construction and installation easy as no screws are visible.

If the retractable type top-hung sliding door has the above structure, it can be used as either a single or double-hung storage type, and the door panel will not be visible when the door is retracted, making it possible to use a large top-hung sliding door even if the hollow wall is thin. can be provided. Furthermore, it is easy to construct and erect (particularly in the case of a single door partition with a single door panel, which is usually difficult to install and remove), it is possible to install and remove the door panel in the case of a single door panel with a single door panel. (This can be easily done by removing part or all of it), and it is safe to use, with no accidents caused by finger jamming.
