Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a structure for closing gaps in folding doors.

[Prior art]

As shown in FIG. 3, a folding door is one in which the upper and lower ends of the vertical frame side of the door are pivotally supported by upper and lower frames, and the folding door rotates around the axis to fold and open. Therefore, unless the vertical stile that is pivoted on the upper and lower frames has a slight gap with the vertical frame, they will come into contact with each other when rotated, resulting in a slight gap even when the door is closed.

This gap impairs airtightness and also does not look good, so as shown in Figure 4,
A gap closing material c was provided protruding toward the side to close the gap.

[Problems to be solved by this idea]

With the above configuration, the gap d created between the stile a and the vertical frame b as seen from the front is large, and the appearance is not good. Further, when the width of the gap closing material c is large, the gap closing material c is easily deformed, and there is a problem that a gap is generated between the gap closing material c and the vertical frame b.

[Means for solving problems]

This idea is based on the vertical frame 1 of the vertical stile 4 of the door 1 of the folding door.
A locking piece 18 whose tip is bent on the surface facing 6,
18 are continuously formed vertically, and the locking piece 1
8, 18 and is attached with an attachment made of a shaped material having a tapered surface portion 20, and one end located on the side in the direction of rotation when opening among the left and right ends in the width direction of the surface of the attachment facing the vertical frame 16. one end closer to the vertical frame 16 side than the other end, and a gap closing material 22 is provided protruding from the one end toward the vertical frame 16, and the surface facing the vertical frame 16 is moved toward the other end. It is formed so as to gradually separate from the vertical frame 16, so that the stile does not come into contact with the vertical frame during rotation, and also reduces the gap between the stile and the vertical frame that can be seen from the front, and also reduces the width of the gap closing material. It is something to do.

〔Example〕

This invention will be explained in detail below based on an embodiment shown in the drawings.

What is shown in FIG. 3 is a folding door, in which synthetic resin doors 1, 1 are attached on the left and right sides, and each door 1 is divided into left and right parts, each consisting of two divided doors 2, 2.
The split door 2 has upper and lower horizontal stiles 3, 3 and left and right vertical stiles 4, 4.
are assembled into square frames, and attachments 5 are attached to opposite sides of each frame 3 and 4. Each attachment 5 is provided with a groove 7, and an integrally formed louver decorative plate 9 whose end is fitted into the groove 7
is embedded.

The divided doors 2, 2 are foldably connected by a hinge 10 to form a single door 1. In the figure, the door 1 on the right side has a shaft 11 protruding upward and downward at the right end, and the door 1 on the left side has a shaft 11 protruding upward and downward at the left end. , 11 on the upper and lower horizontal frames. Further, a roller hanging tool 12 is provided upwardly protruding from the left end of the right door 1 and the right end of the left door 1. 1 is hanging. Further, guide rods 14 are provided below to protrude in correspondence with the roller hangers 12, and are fitted into rails 13 attached to the lower frame.

Among the left and right ends in the width direction of the surface facing the vertical frame 16 of the vertical stile 4 supported by the shafts 11, 11 of the door 1, one end located on the side in the direction of rotation when opening is vertically moved from the other end. Close to the frame 16 side. and stile 4
An attachment 17 is attached to the vertical frame 4 to change the distance between the vertical frame 16 at the left and right ends of the vertical frame 4.

That is, on the left and right ends of the surface of the vertical stile 4 facing the vertical frame 16, there are locking pieces 18 whose tips are bent toward the opposite side.
18 are formed continuously from top to bottom. The attachment 17 is attached by being locked by the locking pieces 18, 18. The attachment 17 includes a proximal portion 19 having a U-shaped cross section, a tapered surface portion 20 extending slightly bent from one of the two parallel surfaces of the proximal portion 19, and a tapered surface portion 20 extending from the other surface of the proximal portion 19. It consists of locking parts 21, 21 which are formed parallel to the end of the surface part 20 and have an arrow-shaped cross section. This attachment 17 is attached with locking portions 21, 21 locked to locking pieces 18, 18 of the vertical stile 4. The proximal portion 19 of the attachment 17 is mounted so as to be located in the rotation direction when the door 1 is opened.

A vertical frame 16 is provided in the vicinity 19 of the attachment 17.
A gap closing material 22 made of vinyl chloride or the like is integrally formed toward the side.

The end on the side where the gap closing material 22 is attached is protruded by the proximal part 19 of the attachment 17, and the tapered surface part 20 is gradually separated from the vertical frame 16 as it goes to the other end. Become.

[Effect of idea]

This invention has the above-mentioned configuration, and a locking piece with a bent tip is formed on the surface of the pivoted one of the left and right vertical stiles of the door facing the vertical frame, and the locking piece has a bent tip. By attaching an attachment made of a shaped material with a tapered surface, the left and right ends in the width direction can be
Since the end located in the direction of rotation when opening is made closer to the vertical frame than the other end, even if the stile rotates, it will not come into contact with the vertical frame. Furthermore, when viewed from the front, the gap between the vertical stile and the vertical frame becomes smaller, resulting in a better appearance. Furthermore, the width of the gap closing material that closes the gap becomes smaller, making it difficult to deform, and good airtightness is maintained. Further, since the tapered surface portion is formed using an attachment, the tapered surface portion and the closing material can be provided only at necessary locations without making the shape of the vertical stile a special shape.
