DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a sliding door which is suspended from an upper side and can be freely opened and closed so that the light does not reach from one side to the other side of the sliding door.

[0002]

2. Description of the Related Art Conventionally, as an example of such a top-hanging sliding door, which conceals the light, there is one disclosed in Japanese Utility Model Laid-Open No. 7-15981 filed by the present applicant. This is done by drilling a long mounting groove in the upper direction of the sliding door in the running direction of the sliding door and inserting the lower part of the light concealing plate long in the width direction of the sliding door into the mounting groove and attaching the light concealing plate on the upper end of the sliding door. Was located at the lower opening of the upper rail.

[0003]

In such a conventional example, in a portion without a runner, a light concealing plate can conceal the light so that the light does not reach from one side of the sliding door to the other side.
There is a problem in that the light concealing plate cannot be attached to the runner shafts at the portions where the runners are at both ends at the upper end of the sliding door, and the light leaks at the runner portion.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to make it possible to conceal light even at a certain portion of a runner and to conceal light over the entire length of the upper end of a sliding door. .

[0005]

SUMMARY OF THE INVENTION In order to attain the above object, the present invention provides a light-hiding structure for an upper-hanging sliding door, wherein a runner 2 mounted on an upper end of a sliding door 1 is hung on an upper rail 3 so as to be able to travel freely. In the part other than the part where the runner 2 of the sliding door 1 is provided, the main light concealing plate 4 is mounted on the upper end of the sliding door 1 so as to protrude upward, and the part of the sliding door 1 where the runner 2 is provided.
The vertical piece 6a and the horizontal piece 6b form a substantially L-shaped cross section.
Place the sub-light concealed plate 6 and place the horizontal piece 6b on the sliding door 1.
Attach to the end and bypass the runner shaft 5 to the vertical piece 6a.
The turning concave portion 13 is provided over the entire vertical length, and the upper end of the vertical piece 6 a of the main light concealing plate 4 and the sub-light concealing plate 6 is located at the lower opening of the upper rail 3. In the portion of the sliding door 1 where the runner 2 is not provided, the light can be hidden by the main light blocking plate 4, and in the portion where the runner 2 is provided, the light can be hidden by the sub light blocking plate 6 bypassing the runner shaft 5, and the total length of the upper end of the sliding door 1 Can be hidden.

It is also preferable that a main light concealing plate 4 and a sub-light concealing plate 6 are mounted so as to protrude upward at the center of the sliding door 1 in the thickness direction.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to an embodiment shown in FIGS. At the upper ends on both sides in the width direction of the sliding door 1, runner mounting recesses 7 are recessed, and at the upper end of the sliding door 1, mounting grooves 8 are formed so as to extend between the runner mounting recesses 7 on both sides. This mounting groove 8 is a sliding door 1
It is drilled at the center in the thickness direction. The runner 2 is formed by mounting a fixed block 9 below the runner shaft 5 and rotatably mounting a runner main body 10 above the runner shaft 5. Rollers 11 are rotatably mounted on both sides of the runner main body 10. is there. The runner 2 is disposed at the upper end on both sides of the sliding door 1. The fixing block 9 is fitted into the runner mounting recess 7, and the fixing screw 16 is screwed in to attach the runner 2 to the sliding door 1. The upper rail 3 is formed in a U-shape with a lip in cross section that opens downward, the upper part of the runner 2 is inserted into the upper rail 3, and the roller 11 is placed on the lip 3 a of the upper rail 3 so as to roll freely. As a result, the sliding door 1 is suspended so that it can run freely. The main light concealed plate 4 is formed in an elongated plate shape,
On both left and right sides of the middle part in the vertical direction, ridges 12 are provided so as to protrude in the longitudinal direction. By inserting the lower part of the main light concealing plate 4 into the mounting groove 8 before hanging the sliding door 1 on the upper rail 3, the main light concealing plate 4 is attached to the upper end of the sliding door 1 without the runner 2. At this time, since the main light concealing plate 4 has the ridge 12, the lower portion of the main light concealing plate 4 has
2 is inserted until it comes to the upper end of the sliding door 1, and the amount of upward projection of the main light concealing plate 4 from the upper end of the sliding door 1 becomes constant.
A sub-light concealing plate 6 is attached to the upper end of the sliding door 1 in the vicinity of where the runner 2 is attached, except for the place where the main light concealing plate 4 is attached. The sub-light concealing plate 6 is formed in a substantially L-shaped cross section by the vertical piece 6a and the horizontal piece 6b,
The vertical piece 6a is provided with a concave portion 13 having a substantially U-shaped cross section that bypasses the runner shaft 5 over the entire length in the vertical direction.
Is provided with a mounting hole 14. The auxiliary light concealing plate 6 places the horizontal piece 6b on the upper end of the sliding door 1 and
Is loosely fitted to the runner shaft 5 and is attached to the upper end of the sliding door 1 by screwing the mounting screw 15 through the mounting hole 14. With the sub-light concealing plate 6 attached, the sub-light concealing plate 6
The end of the vertical piece 6a and the end of the main light concealing plate 4 are butted against each other without a gap. The main light concealing plate 4 is attached to the center of the sliding door 1 in the thickness direction because the main light concealing plate 4 is inserted into the mounting groove 8 in the center of the sliding door 1 in the thickness direction. Hidden plate 6
The vertical piece 6a of the auxiliary light concealing plate 6 is also located at the center of the sliding door 1 in the thickness direction. Main Light Hidden Board 4
When the sliding door 1 to which the auxiliary light concealing plate 6 is attached is hung freely on the upper rail 3 by the runner 2, the upper ends of the main light concealing plate 4 and the sub light concealing plate 6 are located at the lower opening of the upper rail 3, The gap between the upper rail 3 and the upper end of the sliding door 1 is covered with the main light concealing plate 4 and the sub-light concealing plate 5, so that light can be prevented from leaking from one side of the sliding door 1 to the other side.

[0008]

As described above, according to the present invention, the main light concealing plate is mounted on the upper end of the sliding door so as to protrude upward except for the portion where the runner of the sliding door is provided. A sub-light that can be formed into a substantially L-shaped cross section with the horizontal piece
Place the hidden plate and attach the horizontal piece to the upper end of the sliding door
Both of the vertical pieces have a concave curved part that bypasses the runner shaft.
And the length of the primary and secondary light concealed panels
Since the upper end of the piece is located at the lower opening of the upper rail,
In the part of the sliding door that does not have a runner, it can be concealed with the main light concealing board, and in the part with the runner, it can bypass the runner axis and be concealed with the sublight concealing board. With the plate, the light can be hidden over the entire length of the upper end of the sliding door.
