When considering the entrance and exit of wheelchair users from the front door, there should be no step on the upper surface of the lower frame, as in the case of No. 1-7819 and No. 3002107, as well as between the indoor and outdoor floors that sandwich the door. However, since a rail protruding upward is formed on the lower frame of the sliding door, the lower frame itself cannot be flattened.
[0003]
In Japanese Patent Laid-Open No. 5-332068, the upper end of the rail of the lower frame is adjusted to the level of the indoor and outdoor floors to eliminate the step between the rails and the floor surface, eliminating obstacles when traveling in a wheelchair. If the upper surface of the floor is positioned below the outdoor floor, water and debris collected on the lower frame will not be discharged to the outside of the lower frame, and water will not be treated inside or below the lower frame. I do not get.
[0004]
In actual utility flat 1-118075, the upper end of the rail of the lower frame is adjusted to the level of the indoor floor surface, while a step is formed between the floor surface of the outdoor and the grating installed continuously outside the lower frame. By forming a slope between the rails of the lower frame, the obstacles during wheelchair traffic are alleviated. Here, the slope is formed in the grating, but when the slope is formed in the lower frame in this way, the slope protrudes from the opening frame alone to the outdoor side, and the slope is restrained by the vertical frame. As a result, the end support method becomes a problem.
[0005]
The present invention provides a sliding door lower frame that solves an end support problem when a step is provided between the rail and the floor of the room and a slope is formed on the lower frame, a connection structure between the lower frame and the vertical frame, and a sliding door The lower frame mounting structure is proposed.

The lower frame including the attachment is connected to the vertical frame with the end of the lower frame body and the attachment abutting against the prospective piece of the vertical frame, and a small cap and lower frame attached to both ends in the longitudinal direction of the attachment The end of the main body is connected to the vertical frame in a state in which the end of the vertical frame abuts against the expected piece of the vertical frame, but the vertical frame is more than the expected width of the entire lower frame with the attachment added to the lower frame main body as described in claim 3 . If there is a prospective width and the end of the lower frame hits the prospective piece of the vertical frame over the entire width in the prospective direction and the end of the lower frame including the attachment is connected to the vertical frame over the entire width in the prospective direction Therefore, the end portion of the slope is also supported by the vertical frame.
[0011]
The fore edge cap has an upper surface that is continuous with the upper surface of the lower frame body while closing the end surfaces at both ends in the longitudinal direction of the attachment.
[0012]
The attachment that guides the wheelchair's wheels between the rail of the lower frame and the outdoor floor surface is directly attached to the lower frame main body, or directly against the prospective piece of the vertical frame with a small cap, and is attached. Since the shape is constrained by the vertical frame, the problem of deformation of the end portion does not occur.
[0013]
The upper end of the rail of the lower frame is aligned with the level of the indoor floor surface in order to eliminate a step between the indoor floor surface. In order not to collect water on the upper surface of the lower frame, there is a step between the upper surface of the lower frame and the outdoor floor surface, and the lower frame is arranged so that the upper surface is not located below the outdoor floor surface. The
[0014]
In the case of using the small cap, water and dust existing on the lower frame are discharged to the outside by the small cap attached to the attachment. As described above, the top cap continues to the top surface of the lower frame main body to discharge water and dust on the lower frame main body to the outside through the top surface of the small cap regardless of the inclined surface of the attachment.
[0015]
Since water and dust existing on the lower frame move to both ends in the length direction through the upper surface of the lower frame and are discharged from the upper surface of the forehead cap, it is not necessary to treat on or below the lower frame.
[0016]
