Description

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

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

[Conventional technology]

It is preferable to close the door of the laundry room facing the hallway when it is not in use, so that the inside is not visible and the room is neatly 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]

The present invention is based on further consideration of the storage-type folding door proposed above, and has made the storage space of the folding door as small as possible, making the storage space wider and allowing reliable movement with a simple structure. be.

[Means to solve the problem]

Therefore, in this invention, of the two folding doors large enough to cover the front opening, the base folding door is made wider than the front folding door, so that when folding, the hanging door wheel of the front folding door is moved from the side storage upper rail. Slider 14 in 4b
It was then changed to ``and stored.''

[Effect]

With this structure, the door does not protrude too much in front of the front rail, making it possible to reduce the dead space. In other words, as shown in Figure 5, the protrusion trajectory of the conventional folding door on the storage side when the door plate is stored is As shown in the dashed line, as in the present invention, the widths of the two door panels are made different by making the base side folding door 2 larger and the front side folding door 1 smaller. Therefore, the door does not protrude much in front of the front rail, and the folding door on the front side follows the trajectory shown by the chain line, so the dead space is extremely small. In addition, when folding, the upper hanging wheel of the front folding door moves rearward from inside the front upper rail, parallel to the side upper rail, and transfers to the slider in the side storage upper rail that is either integrated with or separate from the side upper rail. As a result, the structure is simple, there are few failures, and it operates reliably.

【Example】

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of the folding door seen from the hallway side, FIG. 2 is an enlarged cross-sectional view taken along line A-A in FIG. 1, and FIG. 3 is an enlarged cross-sectional view taken along line B-B in FIG. FIG. 4 is a perspective view of the slider. FIG. 5 is a schematic plan view showing the opened and closed state. In FIG. 1, the front sides of the folding doors 1 and 2 face the hallway, and the back faces the laundry room. These two folding doors 1 and 2 are large enough to cover the front opening of the laundry room and are hinged. Above the front opening, a front upper rail 3 as seen in FIGS. 2 and 3 is provided, and a side upper rail 4a and a side storage upper rail 4b are provided integrally or separately at almost right angles thereto. . Also provided on the floor are a front lower rail 5 and two side lower rails 6 substantially perpendicular to the front lower rail 5. In the structure of the illustrated embodiment, guide pins 7 and 8 on both sides at the bottom of the two folding doors 1 and 2 slide within the rail grooves of the lower front rail 5 and the lower side rail 6. At the base of the front side folding door 2 is a pivot suspension wheel 9.
is provided, and a hanging door wheel 1 is installed on the top of the folding door 1 on the forward side.
0 is set. The pivot suspension wheel 9 of the front side folding door 2 has a structure in which four wheels are provided on the body, and the body part is rotatably supported on the base side folding door 2. Move within the rail 4a. Hanging door wheel 1 at the top of the front folding door 1
0 is rotatably supported and rolls on the front upper rail 3. The hanging door wheel 10 has four wheels in FIG. 1, but if it has two wheels as shown in FIGS. 2 to 4, the slider width becomes narrower, which is a preferable embodiment. The two folding doors 1 and 2 have different widths, and the width of the forward folding door 1 is smaller than the width of the base folding door 2. As shown in FIG. 1, the ratio of the forward folding door to the base folding door is approximately 1:2. When this ratio is large, the inner dead space becomes large, and when the ratio is small, when the door is folded, the hanging wheels 9 and 10
The interval between the folding doors is small, and the holding force against tilting in the width direction of the folding door is insufficient, making it unstable. Furthermore, the amount of protrusion toward the hallway side becomes large, so from a design perspective, the ratio of the door width should be set to approximately 1:2. is optimal. The pivot upper suspension wheel 9 moves along the side upper rail 4a, and the front folding door 1 follows the movement of the base folding door 2 and moves along the front upper rail 3, but the folding ends when it is stored. Then, the hanging door wheel 10 moves from the front upper rail 3 to the slider 14 provided in the side storage upper rail 4b. The slider 14 for this purpose is provided so as to be slidable inside the side storage upper rail 4b.
As shown in Figure 4, the intrusion direction of the hanging door wheel 10 is in an open state, and the guide groove 15 for the support rod of the hanging door wheel 10 is provided at the bottom, and the lower side is in an open state, so that the hanging door wheel 10 of the forward folding door 1 rides. The structure is such that it can be done. Note that there is a bearing between the slider and the rail.
Alternatively, smoother movement can be achieved by inserting small rollers.

[Effect of the idea]

With a wall storage structure for folding doors as shown above,
Door panels 1 and 2 for laundry rooms, etc. facing the hallway of the residence
It is possible to reduce the dead space created when the door plate is stored in the corner part P formed by the side wall. In other words, as shown in Fig. 5, the locus of the protrusion on the storage side of the conventional folding door when the door panels are stored is as shown by the dashed line, but unlike the present invention, when the width of the two door panels is By making the base folding door 2 large and the front folding door 1 small, with different widths, the doors do not protrude too much in front of the front rail, and the base folding door is shown by the chain line. Since it follows a similar trajectory, the dead space is extremely small. In addition, when folding, the upper hanging wheel of the front folding door moves rearward from inside the front upper rail, parallel to the side upper rail, and transfers to the slider in the side storage upper rail that is either integrated with or separate from the side upper rail. In addition, by using a slider, compared to the conventional door with a sliding rail and door roller,
It has a simple structure, high strength, and operates reliably.
