Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sliding door.
[0002]
[Prior art]
Conventionally, as shown in FIG. 3, the pair of sliding doors b that are slidable horizontally within the frame body a are positions where one sliding door b completely overlaps the other sliding door b in order to increase the effective opening. And an effective opening that is about half the width of the frame body a is obtained.
[0003]
Accordingly, the handle c of the sliding door b is also provided so as to be recessed in the vertical beam d so that the sliding door b does not buffer even if the sliding doors b overlap each other.
[0004]
[Problems to be solved by the invention]
However, in the conventional sliding door b, when the sliding door b is closed from a state where the sliding doors b are completely overlapped with each other, there is a problem that the handle c is hidden and the operation becomes difficult.
[0005]
Further, the handle c is recessed so as not to be buffered even if the sliding doors b overlap each other, and since it has to be provided on both sides of the vertical beam d, it can be formed only to the extent that a finger is caught. Therefore, for an elderly person etc., the opening and closing of the sliding door b becomes troublesome.
[0006]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a sliding door structure that can be easily opened and closed and can secure a sufficient effective opening.
[0007]
[Means for Solving the Problems]
Sliding door structure of the present invention for solving the above problems, it comprises a pair of outer door and Uchito to the frame body to slide the frame body horizontally been made openable, outer door door end stile On the inside of the door, a stopper is provided to abut against the summit of the inner door so that the outer door and the inner door do not completely overlap with each other. On the outside of the front vertical rod, a handrail is provided that includes a support leg protruding with an offset interval away from the side frame of the door frame, and a handle body fixed between the support legs. The trailing part is formed to have a narrow width that allows the handrail support legs to be fixed, and by sliding the outer door or the inner door with the handrail, the outer door or the inner door and the handrail are separated from each other. It can be opened and closed without buffering.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
FIG. 1 shows an outline of the overall configuration of the sliding door structure, and FIG. 2 shows the same cross-sectional view.
[0011]
That is, in this sliding door structure, a pair of outer door 2 and inner door 3 are slidable in the entrance frame 1, the outer door 2 is provided with a stopper 4, and the inner door 3 is provided with a handrail 5. .
[0012]
The entrance frame 1 is framed in a rectangular shape by a lower frame 11, an upper frame 12 and both side frames 13. The lower frame 11 is provided with two parallel rails 11a and 11b. The lower frame 11 is provided on the floor surface F. The upper frame 12 is also provided with two rails (not shown) that are parallel to each other in the same manner as the lower frame 11. The upper frame 12 is assembled in a gate shape with both side frames 13 and provided on the lower frame 11.
[0013]
The outer door 2 is framed in a rectangular shape by a lower beam 21, an upper beam 22, a doorside vertical beam 23, and a calling vertical beam 24. Of the outer door 2 framed in a rectangular shape, a glass plate 25 is provided on the inner side A, and a lattice plate 26 is provided on the outer side B. The outer door 2 is fitted into a rail 11a outside the entrance frame 1, and can be slid along the rail 11a in the entrance frame 1.
[0014]
Similarly to the outer door 2, the inner door 3 is framed in a rectangular shape by a lower rail 31, an upper rail 32, a door-end vertical rod 33, and a sump rod 34. Of the inner door 3 framed in a rectangular shape, a glass plate 35 is provided on the inner side A, and a lattice plate 36 is provided on the outer side B. The inner door 3 is fitted into a rail 11b inside the entrance frame 1, and can be slid along the rail 11b in the entrance frame 1.
[0015]
The outer door 2 and the inner door 3 are in a state in which the doorside vertical fence 23 of the outer door 2 and the entrance frame 1 are closed, and the doorside vertical fence 33 of the inner door 3 and the entrance frame 1 are closed. The entrance frame 1 is brought into a closed state by overlapping the sump wall 24 of the outer door and the sump wall 34 of the inner door 3.
[0016]
The stopper 4 is provided on the inner side A of the doorside vertical shaft 23 of the outer door 2, and comes into contact with the sump vertical shaft 34 of the inner door 3. The stopper 4 abuts on the sump 34 of the inner door 3 so that the outer door 2 and the inner door 3 do not completely overlap, and one end of the door shaft 33 of the inner door 3 as viewed from the outer side B. The part is exposed as the unremaining part 33a, and a part of the door-end vertical shaft 23 of the outer door 2 is exposed as the unremaining part 23a when viewed from the inside A.
[0017]
The handrail 5 is fixed between the pair of support legs 51, 51 projecting outward from the left-side portion 33 a of the door-end vertical shaft 33 of the inner door 3, and the support legs 51, 51. It is comprised by the rod-shaped handle main body 52 made | formed along the vertical rod 33. As shown in FIG. If the support legs 51 and 51 are simply provided on the outer side B from the remaining portion 33a, the distance between the support frame 51 and the side frame 13 of the entrance frame 1 cannot be sufficiently obtained with the inner door 3 closed. Therefore, an offset interval D is provided in a direction away from the side frame 13. Further, the support legs 51 and 51 are projected so that the handle main body 52 is positioned on the outer side B further than the outer door 2.
[0018]
Since the handrail 5 is provided in the left-side portion 33 a of the door shaft 33 of the inner door 3, it is not buffered with the outer door 2. On the contrary, the leaving part 33a is sufficient to fix the support leg 51 of the handrail 5, and it is not necessary to leave the leaving part 33a large, so that the outer door 2 and the inner door 3 are connected to each other. It is possible to obtain a sufficient effective opening that is equivalent to opening in the overlapped state.
[0019]
Further, since the handrail 5 is provided so as to protrude further to the outer side B of the outer door 2, a conventional handle (illustrated) recessed in the left-side portion 33 a of the door-end vertical rod 33 of the inner door 3 is illustrated. Compared with (omitted) etc., the opening / closing operation can be performed very easily.
[0020]
In addition, on the outer side B of the door toe vertical shaft 23 of the outer door 2, a pair of support legs 61 and 61 projecting from the outer side B are fixed between the support legs 61 and 61. A handrail 6 constituted by a rod-shaped handle main body 62 which is adapted to follow is provided. This support leg 61 is also provided with an offset interval D in a direction away from the side frame 13 of the entrance frame 1. Further, the handle main body 61 is aligned at the same protruding position as the handle main body 51 provided in the inner door 2.
[0021]
Moreover, in this Embodiment, although the handrails 5 and 6 are provided only in the outer side B of the inner door 2 and the outer door 3, the same handrail 5 is provided also in the inner side A of these inner doors 2 and the outer door 3, 6 may be provided.
[0022]
Further, in the present embodiment, the entrance frame 1 is formed in a rectangular shape by the lower frame 11, the upper frame 12, and the both side frames 13, 13, but there is no lower frame 11, and the outer door 2 and the inner door 3 are placed on the upper side. It may be slidable in a state of being suspended from the frame 12. Moreover, this sliding door structure may be provided in a desired site inside the house other than the entrance.
[0023]
【The invention's effect】
As described above, according to the present invention, the remaining portion is formed to have a narrow width enough to fix the support leg of the handrail , so that a sufficient effective opening can be secured. In addition, the handrail is composed of a support leg protruding with an offset interval in a direction away from the side frame of the door frame, and a handle body fixed between the support legs, so that it can be grasped firmly by hand. It can be opened and closed easily even by elderly people.
