DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door structure.

[0002]

2. Description of the Related Art Conventionally, as a type of a sliding door device having a door wheel at a lower portion used for an entrance of an ordinary house, generally, a so-called "kendon system" is generally used. To assemble the door, first insert the sliding door upper frame into the opening upper frame rail groove, lift the entire unit once, and then move the door roller to the lower frame (sill).
The mounting and dismounting method of mounting on a rail was adopted. Therefore, in this method, it is necessary to make a relatively large gap (escape) between the upper and lower parts for attachment and detachment.

[0003]

In the case of the above-mentioned sliding door configuration, for example, when the family includes a disabled person or an elderly person who uses a wheelchair, the bathroom undressing room floor entrance / exit sill, the bathroom floor, etc. With a flat floor without steps,
The opening of the bathroom entrance is usually 2 to allow wheelchairs to pass.
It is necessary to increase the opening width of the entrance by setting the number of sliding doors to three, for example.

However, in such a case, when the number of sliding doors is set to, for example, three at the bathroom doorway having a predetermined height H and the entire width W in an ordinary house, the width of the open doorway is usually two. From approximately W / 2 to 2
Although it increases to W / 3, the aspect ratio of each sliding door increases from 2H / W to 3H / W, respectively, and becomes a vertically long shape.
When opening and closing the sliding door, the rolling resistance of the sliding door on the moving side direction increases to some extent, or when operating above the sliding door,
There is a possibility that the upper part of the sliding door falls down in the moving side direction to cause twisting, and the sliding door cannot be opened and closed smoothly. This tendency naturally becomes more remarkable as the number of sliding doors increases.

[0005] The present invention, in the above cases,
It is an object of the present invention to provide a sliding door structure that can be smoothly opened and closed without causing twisting even when the aspect ratio of the sliding door is relatively increased.

[0006]

According to the present invention, there is provided a sliding door apparatus which moves on an upper frame seal portion having a cross section of a lower opening groove and a sill rail portion of an entrance opening. The height of the top of the upper frame having a groove-shaped cross section is selected to be lower than the height of the lower surface of the upper frame, and the inside of the groove of the upper frame is longer than the width so as to be slidable in the width direction of the sliding door. The object is achieved by disposing the bar-shaped connecting member for engaging the upper frame rail.

[0007]

Since the connecting member as described above is provided in the cross section of the upper frame of the sliding door, the engaging length in the width direction with the opening upper frame rail portion when the sliding door is opened and closed is substantially larger than the sliding door width. Since the sliding door is long, the tendency of the sliding door to twist is reduced, and smooth opening and closing can be performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments.
FIG. 1 is a schematic perspective view of a sliding door structure according to an embodiment of the present invention, and FIG. In both figures,
Reference numeral 1 denotes, for example, one sliding door having three components. Reference numeral 2 denotes an upper frame having an upwardly open groove-shaped cross section. Reference numeral 3 denotes an upper frame rail portion of the entrance opening, which has a triple downward open groove-shaped cross section. The height of the sliding door 1 to the top of the upper frame 2 is determined to be slightly lower than the height of the lower surface of the upper frame 3 of the opening. A rod-shaped connecting member 4 is provided so as to be movable in the sliding door width direction. The length of the sliding door 4 is longer than the width of the sliding door 3.
For example, in the case of the three-piece sliding door shown in the figure, this length is within 2/3 of the width of the entrance opening.

In the lower half portion of the connecting member 4, elongated holes 4a penetrating on both side surfaces thereof are formed so as to have a length substantially close to both ends.
The slots 4 are provided on both sides of the groove of the upper frame 2 respectively.
A pair of small screws are fixedly provided as guide pins 5 so as to penetrate the sliding door 1, and the connecting member 4 is configured to be relatively movable with respect to the sliding door 1 within the range of the elongated hole 4 a.

Therefore, each sliding door 1 is opened and closed with a width substantially larger than the original width, that is, with a small aspect ratio. Can be done. In addition, reference numeral 6 shown in FIG. 1 denotes an opening vertical frame (not shown) when the connecting member 4 moves.
5 shows an elastic piece for cushioning when the vehicle collides with the slab. The material of the connection member 4 is wood, aluminum, synthetic resin, or the like.
An easily slidable material having appropriate strength can be selected, and if both end faces are appropriately chamfered, insertion during assembly is easy and sliding is smooth.

Although the above embodiment has been described with reference to the case of a three-sliding sliding door, it is needless to say that the length may be selected so as not to hinder movement according to the number of the sliding doors. is there.

[0012]

As described above, according to the present invention, since the upper frame of the sliding door having a relatively large aspect ratio and the sliding connection member longer than the width of the sliding door are provided, there is a tendency that twisting occurs when opening and closing. The opening and closing operation is performed smoothly and the top of the sliding door upper frame is set lower than the upper frame rail, so it is easy to attach and detach, and it is necessary to attach and detach Since no clearance gap is required, the sealing performance of the opening is also improved.
