DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower frame and a sliding door, which are entrances and exits of a bathroom, an entrance, a service entrance, a veranda and the like. It relates to the lower frame and the sliding door.

[0002]

2. Description of the Related Art As a conventional lower frame of an entrance which facilitates the passage of a wheelchair, for example, as shown in Japanese Patent Application Laid-Open No. Hei 6-93771, a lower frame of a sash at an entrance of a veranda is provided between an outdoor side and an indoor side. The height of the step is about 15 to 20 mm from the conventional 45 to 65 mm, and the height is almost the same.
It has been known that the outdoor end of the connecting piece of the rail portion is formed on a slope to facilitate passage of a wheelchair.

[0003]

The lower frame of the sash described above reduces the level difference between the outside and the inside of the sash to facilitate the passage of a wheelchair, but the gap between the two rails remains unchanged. Therefore, the wheelchair does not pass smoothly, the gap is about 25 mm, and the width of the wheelchair tire is about 15 mm, so when the front wheel turns sideways and becomes parallel to the rail, it may fall into the gap. There was a problem because it was not always safe. Therefore, the present invention has been made to solve the above-mentioned problem and to make the gap between the rails narrower than the width of the tire of the front wheel of the wheelchair so that even when the front wheel is turned sideways, it can safely and easily pass without falling. The purpose of the present invention is to provide a lower frame and a sliding door for a doorway which can be operated.

[0004]

For thick INVENTION SUMMARY OF THE INVENTION, to attain the aforementioned object, the indoor side, eliminating the step of each partition piece and the height of each rail of the outdoor side and respectively substantially the same height, between the rail A lower piece of the entrance is constructed by erecting a spacing piece having a T-shaped cross section having substantially the same height as the rail, and a drawer to be built in this lower frame.
A part that hangs between the rails at the lower end surface on the indoor side and the outdoor side of the door
Minutes are recessed inward to approach the rails.
The T-shaped spacer can be installed close to the
A ridge is provided along the length of the
In addition, by configuring the sliding door of the doorway, the lower frame of the doorway so as to reduce the gap generated between the rails when the sliding door is opened.
And a sliding door .

Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. The lower frame of the doorway of the present invention is used for a lower frame of a sliding door at a portion serving as an entrance such as a bathroom, an entrance, a self-service opening, a veranda, and FIG. 4 shows three doors at the entrance of the bathroom using the lower frame. FIG. 1 shows the lower frame of the three sliding doors in an embodiment in which sliding doors are built.
The three sliding doors have three rails 5, 5, as shown in FIG.
5 is opened by pulling the handle 11 at the left end to the right, and the sliding door 10 at the left end is moved to the right end by pushing the next sliding door 10 by the interlocking portion 12 provided on the side surface thereof. Thus, an entrance having a width of about two sliding doors is formed, so that people and wheelchairs can enter and exit the bathroom through this opening. The lower frame 1 used for such a bathroom doorway is constituted by a sash frame made by extrusion molding as shown in FIG. 1, and the height of the bathroom-side partition 2 and the dressing-room-side partition 3 is set to the height of the bathroom. Although the side is about 10 mm lower, it is almost the same height, so that elderly people and wheelchairs can pass easily. A rail mounting portion 4 is provided between the two partition pieces 2 and 3.
Is slightly inclined toward the bathroom so that the intruded hot water flows toward the bathroom. On the surface of the rail mounting portion 4, three rails 5, 5, 5 are provided integrally at the same height as the height of the partition 2 on the bathroom side at regular intervals. The door roller 8 attached to the lower frame 16 of the sliding door 10 is fitted and moves on the rail 5 to open and close the entrance. Also, between the rails 5, a spacing piece 6 is provided integrally with the rail mounting portion 4 as shown in FIGS. 1 and 5 in parallel with the rails 5 so as to close the gap. The spacing piece 6 has the same length and the same height as the rail 5 and has a T-shaped cross section so as to be as close to the rail 5 as possible. The distance between the head 7 is reduced to about 7.1 mm, which is smaller than the width of the front wheel tires of 15 mm. When the front wheel of the wheel chair is parallel to the rail 5, it is installed so that it does not fall between the rails. Have been. In the bathroom, the end of the partition 2 is bent toward the rail to narrow the gap with the rail.

The gap between the rails can be reduced by providing the spacing piece 6 so as not to obstruct the passage of the elderly and the wheelchair, but the expected width of the lower end of the sliding door 10 is reduced as shown in FIG. Thereby, the head 7 of the spacing piece 6 can be brought closer to the rail 5, and the gap between the rails generated when the sliding door is opened can be further reduced. Sliding door 1
The lower end surfaces 14, 14, 17, 17 of the vertical frame 13 and lower frame 16 on the bathroom side and the dressing room side are suspended to the side of the rail 5, so that they have the same height as the rail 5. Cannot be brought close to the rail 5, and the sliding door 10
Is opened, half of the expected width of the vertical frame 13 and the lower frame 16 always remains as a gap between the rails 5. In order to reduce this gap, the lower end surfaces 14 on both sides of the vertical frame 13 and the lower frame 16 are reduced. , 14, 17, 17 hanging parts 15, 15, 1
8 and 18 are recessed inwardly so as not to hinder the rotation of the door roller 8 to reduce the expected width so that the head 7 of the spacing piece 6 can be as close to the rail 5 as possible. .
FIG. 2 shows the joint between the lower end of the vertical frame 13 of the sliding door 10 and the lower frame 16. The lower end 16 of the lower frame 16 on the bathroom side and the dressing room side is on the rail 5 side. The hanging parts 18, 18 hanging down on the rail 5 are configured to be recessed inward so as to approach the side of the rail 5 so as not to hinder the rotation of the door roller 8, and the boundary between the hanging parts 18, 18. The lower frame 16
A ridge 19 is provided in the length direction of the lower frame 16 to improve the strength of the lower frame 16 and to fit the lower frame 13 to the lower side of the vertical frame 13 as shown in FIG. Is configured to be positioned by abutting the lower ends thereof. At the lower end of the vertical frame 13, the lower frame 16 has the same cross-sectional shape as the hanging portions 18, 18 on the bathroom side and the dressing room side of the lower frame 16. The hanging portions 15, on the bathroom side and the dressing room side are made of synthetic resin. The upper and lower parts 15 and 15 are connected together at the upper part, and the integrally formed mounting member is fitted and attached. As shown in FIG. Are arranged so as to be flush with the side surfaces of the hanging portions 18 on both sides of the rail 5 and approach the side of the rail 5. In addition, the connecting side of the hanging part 15 is shortened by the length of the fitting part of the lower frame 16, butted and connected to the end of the lower frame 16, and the lower end of the vertical frame 13 is located on the upper part of the ridge 19. They are placed, positioned and connected. The lower frame 16 connected to the lower end of the vertical frame 13 is tightened with screws 20 from the side of the vertical frame 13, and the sliding door 10 is assembled.
