[0003]
However, in order to ensure the maximum effective opening width at the opening, especially when the sliding door is opened, it is necessary to provide a door pocket along the wall next to the opening, which requires extra installation space. Therefore, there is a disadvantage that the installation position is limited to a place where a wall or the like is located beside the opening.
[0004]
On the other hand, some doors do not require a door pocket part and can secure a relatively large effective opening width at the opening. However, folding doors require an operation of turning by pushing or pulling in by hand when opening and closing, and for a disabled person or a care recipient using a wheelchair, opening and closing operations are not as simple as sliding doors and not easy. There is a disadvantage that.
[0005]
Therefore, in order to take advantage of the advantages of a sliding door whose opening and closing operation is simple and simple and the advantage of a folding door capable of securing a wide effective opening width, a folding door type sliding door device combining a sliding door and a folding door structure has been proposed.
[0006]
In this conventional folding door type sliding door device, a folding door body comprising two foldable folding door panels is rotatably connected by a link mechanism to a sliding door panel on the short side of the door having a handle so as to form a door. And the door is assembled to the opening of the wall so that it can be opened and closed freely. On the other hand, the inner guide rail and the outer guide rail are arranged in two rows on the wall above the opening and on the floor below. The inner and outer guide rails are fixed in parallel at an interval in an anticipated direction orthogonal to the opening and closing direction, and the folding door body is slidably engaged with the upper and lower inner guide rails via a connecting portion, while the sliding door panel is vertically moved. Are slidably engaged with the outer guide rails via a connecting portion to guide in the opening and closing direction. Then, when the sliding door panel is slid left and right with the handle, the folding door body is slid and opened and closed in conjunction with the sliding (for example, see Patent Document 1).
[0007]

Thus, as shown in FIGS. 1 and 2, when the door is closed, the folding door body 20 and the sliding door panel 15 are connected in series with the vertical frame surfaces facing each other, and the door A is entirely flush. . Thus, when the door A is in the closed state, the operating lever 40 of the folding door starting means E is in a state where the abutting portion 43a is in contact with the front surface 10a of the guide rail body G.
[0025]
Now, in the folding door type sliding door apparatus having the above-described configuration, when opening the now closed door A, the user slides the sliding door panel 15 toward the door butt side with a handle (not shown). At this time, when the door rollers 25a roll on the traveling paths 12a of the guide rail 12, and the sliding door panel 15 moves straight under the guidance of the guide rail 12, the folding door body 20 is moved according to the initial opening operation of the sliding door panel 15. , The pressing pin 38 of the folding door starting means E presses the operating lever 43 along the slope of the tapered portion 43b. When pressed by the tapered portion 43b, the operating lever 43 rotates clockwise as shown in FIG. 6 because the abutting portion 43a is in contact with the front surface 10a of the guide rail body G. Kicked out like that. Then, triggered by the kicking out of the operating lever 43, the door end side folding door panel 19 interlocks and starts pivoting in the folding direction in which the door tip side is separated from the wall W with the pivot shaft 53 and the pivot 56 as fulcrums. .
[0026]
When the door bottom side folding door panel 19 starts to rotate in this way, the interval between the two folding door panels 18 and 19 is reduced, and the gear hinge 30 is moved according to the movement as shown in FIG. -Following the engagement of 34, the bent portions 35a and 35b of the bent plate portion 35 swing while bending. Then, in conjunction with the movement of the gear hinge 30, the door-side folding door panel 18 also starts to rotate in the folding direction in which the door end is separated from the wall W, with the pivots 46 serving as fulcrums.
[0027]
When the sliding door panel 15 is further slid in the opening direction and the operating lever 43 is pressed by the pressing pin 38 of the folding door starting means E by the tapered portion 43b, both the folding door panels 18 and 19 turn in the folding direction accordingly. On the other hand, as shown in FIG. 8, the gear hinge 30 follows through the meshing of the teeth 31, 32, 33 and 34, and the bent portions 35 a and 35 b of the bent plate 35 swing while bending. As shown in FIG. 7, the folding door body 20 gradually bends in a C-shape. Further, when the sliding door panel 15 is further slid in the opening direction, the folding door body 20 is further sharply bent while turning the both folding door panels 18 and 19, and the door A is gradually opened at the door tip side. Thereafter, when the folding door panels 18 and 19 are further turned in the folding direction, the folding door body 20 is folded as shown in FIGS. 10 to 12, and the opening S is fully opened.
[0028]
Conversely, when closing the door A, the user similarly holds the handle and pulls the sliding door panel 15 in the closing direction toward the door tip side. Then, the folding door body 20 slides in the closing direction together with the sliding door panel 15 while turning the folding door panels 18 and 19 in a direction opposite to the opening direction. Thereafter, when the vertical frame surface on the front side of the sliding door panel 15 comes into contact with the door stop, the opening S is closed by the door A as shown in FIGS. 1 and 2.
[0029]
According to the first aspect of the present invention, by combining the structure of the sliding door and the folding door, the advantage of the sliding door that can be easily opened and closed and the effective opening width in the opening can be reduced. The advantages of folding doors that can be secured widely can be utilized, and at the same time, there is no need to secure a large door installation space at the opening to increase the thickness of the door in the expected direction as in the conventional structure. The problem that the panel and the panel are displaced in the expected direction and diagonally connected is also eliminated, thereby minimizing the door installation space and minimizing the appearance even if the sliding door and the folding door are combined. The effect of enhancing the beauty can be exhibited.
[0030]
In addition, a guide rail that guides the folding door body and sliding door panel is provided on the floor below the opening as in the past, so that the adverse effect of generating a step on the floor can be eliminated. Can be well adapted.
[0031]
In addition, since both folding door panels are connected so as to be freely foldable by meshing the teeth of a gear hinge having at least a pair of teeth, folding door starting means is provided between the two folding door panels that are the bent portions of the folding door body. When sliding the sliding door panel to open and close the door, the folding door body bends more smoothly with less resistance, making it extremely easy to open and close the door without any load, even by a disabled person or a care recipient using a wheelchair. it can.
