Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a side wall storage type folding door consisting of two doors, which is suitable for the door of a storage space close to the door of a house or a laundry room facing a hallway.

[Conventional technology]

It is preferable to close the door of a laundry room facing the hallway when it is not in use, as this will prevent the inside from being seen and keep it neat and tidy. However, if the door remains open during use, it obstructs the narrow passage and is inconvenient. Therefore, we have previously developed and proposed a retractable folding door in which the open door is stored in the side wall during use (Japanese Patent Laid-Open No. 58-222275).

[Problem that the idea aims to solve]

Conventional folding doors of this type were placed inside the laundry room when stored, creating a dead space that could not be used. In addition, in Japanese Utility Model Publication No. 56-74159, there is a device in which the door of the altar room is foldable so that it can be stored in the depth direction, but when the door is large and heavy, such as in a laundry room, It is necessary to secure the door plate stably when it is opened. Therefore, even when the door is opened, heavy objects are securely held at the top and bottom of the door.
The challenge was to provide a reliable locking mechanism to eliminate rattling.

[Means to solve the problem]

The present invention has been developed by further studying the previously proposed retractable folding door, and has made it possible to increase stability by adding a locking mechanism. A side upper rail and a side lower rail are provided above and below along the wall surface, and the front upper rail 3 of the front opening is provided almost at right angles to the side upper rail 4, and two door panels covering the front opening, that is, a front folding The door 1 and the base folding door 2 are hinged so that they can rotate freely so that the folded surface protrudes outward from the storage space and the inner surfaces meet, and the base folding door is attached to the upper side rail and the lower side rail, respectively. A storage type folding door which is hinged to a storage guide with a hanging wheel and a storage guide with a supporting wheel that move along the folding door, and has a guide 5 projected from the upper part of the front folding door guided by the front upper rail and the side upper rail. At the door,
A stopper 9 having a protrusion 14 for locking the support wheel 8 of the storage guide with support wheel is provided on the lower side rail 24 side, and the operating rod 26 of the stopper 9 is released by contact with the front folding door 1. It is located at a point set in the position.

[Effect]

With the structure of the present invention, when folding toward the hallway side, that is, so that the surface of the fold protrudes outside the storage space and the inner surfaces meet, the stopper attached to the lower side rail 24 9
The protrusion 14 locks the support wheel 8 of the storage guide with support wheel 7', so that the storage guide with support wheel 7' does not move.
Can be operated stably. Next, the two folded door plates are stored on the wall of a storage space such as a laundry room along the side upper rail, but at this time, the door plates come into contact with the action rod 26 of the stopper 9 attached to the side lower rail. By this, the protrusion 1 of the stopper
4 is released from the support wheel 8, and the storage guide becomes able to move backward. This automatically allows the entire folding door to move backwards.

【Example】

Embodiments of the present invention will be described in detail below with reference to the illustrative drawings. Fig. 1 is a perspective view of the storage type folding door, Fig. 2 is an enlarged cross-sectional view taken along line A-A in Fig. 1, Fig. 3 is an enlarged cross-sectional view taken along line B-B in Fig. The figure shows the state when stored, and is an enlarged cross-sectional view taken along the line CC in FIG. FIG. 5 is a front view of another embodiment of the front folding door guide, and FIG. 6 is a perspective view thereof. 7 to 9 show structural examples of the stopper, FIGS. 7 and 8 are a plan view and a front view of the first example, and FIG. 9 is a plan view of the second example. In FIG. 1, the surfaces of the folding doors 1 and 2 are on the back side of the figure, facing the hallway side, that is, the outside of the storage space, and the front faces facing the laundry room. These two folding doors, front folding door 1 and base folding door 2, are large enough to cover the front opening of the laundry room. It protrudes from the top and is hinged so that the inner surfaces meet. The front folding door 1 has upper and lower hinges 27 and 28 by the base folding door 2.
The load is supported by An upper rail 3 is provided above the front opening, and a side upper rail 4 is provided approximately at right angles thereto. As shown in Fig. 1, a guide 5 is provided at the top of the front end of the front folding door 1, and as shown in Fig. 2, the guide 5 moves inside the front upper rail 3 with the side surface of the guide being regulated by the lip of the rail. do. When the door plate is a heavy object, the guide 5 has a door wheel structure as shown in FIGS. 5 and 6, and is rolled within the upper rail 3 while supporting the load of the front folding door 1. When the front side folding door 2 is in close contact with each other, the guide 5 enters the upper rail side guide receiver 11 as shown in FIG. 6, and when the folding door is stored, it may be structured to slide along the side upper rail. This structure is preferable because the upper rail is hidden behind the door when the door is closed. The base side folding door 2 is hinged 10 to a storage guide 7 provided with an upper hanging wheel 6.
It is hinged by. The storage guide 7' with support wheels functions like a trolley, and in this example, as shown in FIG. The structure is such that a pair of rolling support wheels 8 support the base folding door 2 by hinges. In such a retractable folding door, the folding operation can be performed stably and reliably by restricting the rolling of the support wheel 8, which is the rotation fulcrum of the folding door, until the folding door is folded during storage. Ru. for that purpose,
Like the stopper 9 shown in FIGS. 7 and 8, a locking protrusion 14 is attached to the leaf spring 13 of the working rod 26, one end of which is fixed to the rail, and a roller 15 is attached to the curved end.
, and the fin part 16 provided by a partial notch in the frame of the support wheel 8 is locked to the locking protrusion 14, or like the stopper 9 shown in FIG. The supporting wheel 8 is supported by the locking protrusion 14 of the locking plate 18, which is a working rod 26 which is rotatable on the rail, elastically supported by a spring 17, and has a hook-shaped end and a roller 15. It is preferable to have a structure in which the wheels of the vehicle are fixed. This is because the diameter of the wheel is the full height of the guide rail as shown in FIG. 8, so the vehicle cannot ride over the locking protrusion 14 and retreat. When the folded door panel is moved backward, both the structures shown in FIGS. 7 and 9 move the roller 15 by the lower fin 25 of the door panel, as shown by the imaginary line in FIG. Push to the left of the illustration to automatically release the stopper. Note that the storage guide 7 with an upper suspension wheel and the storage guide 7' with a support wheel may be connected.

[Effect of the idea]

The storage-type folding door with the above structure enables smooth opening and closing even when the door panel is large and heavy, such as in a laundry room. When the door plate comes into contact with the operating rod, the stopper is automatically released, so it is not a nuisance, and when using the laundry room, etc., it can be folded toward the hallway as shown by the two-dot chain line in Figure 1. Then, it is stored on the wall of the laundry room along the side upper rail. Therefore, when storing the laundry equipment, it is now possible to place the laundry equipment in the corner part P, which used to be a dead space due to a folding door in the laundry room, and the storage space has been expanded. In addition, the structure is simple and there is no need for a lower front rail, making it safe and easy to use. The product of the present invention is thus ideal as a folding door for a storage space such as a laundry room facing a hallway.
