DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower frame for a sliding door and a connection structure between a lower frame of the sliding door and a vertical frame.

[0002]

2. Description of the Related Art When considering the entrance and exit of a wheelchair user from an entrance door, the actual room No. 1-7819 and actual climbing, as well as the space between the room sandwiching the door and the outdoor floor surface, are taken into consideration.
The problem is that there is no step on the upper surface of the lower frame as in Japanese Patent No. 3002107, but since the lower frame of the sliding door is formed with a rail protruding upward, the lower frame itself cannot be flattened.

In Japanese Patent Application 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, thereby eliminating obstacles during wheelchair traffic. However, if the upper surface of the lower frame is located below the outdoor floor, water and debris accumulated on the lower frame cannot be discharged to the outside of the lower frame. I have to process it.

In Japanese Utility Model Laid-Open No. 1-118075, while the upper end of the rail of the lower frame is adjusted to the level of the indoor floor surface, a step is formed between the rail and the outdoor floor surface, and the rail is continuously installed outside the lower frame. By forming a slope between the grating and the lower rail, obstacles during wheelchair traffic are reduced. Here, the slope is formed in grating, but if the slope is formed in the lower frame in this way, the slope will protrude from the opening frame to the outside of the room alone, and the slope will be restrained by the vertical frame. The problem is how to support the ends.

The present invention provides a step between a rail and a floor in a room to solve a problem of supporting an end portion when a slope is formed in a lower frame, and to solve a problem of drainage from a lower frame by a sliding door. The present invention proposes a connection structure between a frame, a lower frame, and a vertical frame.

[0006]

According to the first aspect of the present invention, the slope is inclined downward from the upper end of the rail to the height of the upper surface of the lower frame body from the indoor side to the outdoor side, from the indoor side to the outdoor side of the rail positioned closest to the outdoor side. By attaching the attachment that forms the slope with the surface, it is possible to connect the end of the lower frame including the attachment to the vertical frame over the entire width in the expected direction, and to attach the end of the slope Obtain the state of being supported by the vertical frame.

The attachment gently guides the wheel of the wheelchair from the rail near the outdoor to the outdoor floor or vice versa by the inclined surface, and eliminates the impact on the wheel caused by the step between the rail and the outdoor floor. .

The lower frame including the attachment is connected to the vertical frame with the end of the lower frame main body and the attachment abutting against a prospective piece of the vertical frame. The fore cap attached to both ends in the vertical direction and the end of the lower frame main body are connected to the vertical frame in a state where they abut against the prospective pieces of the vertical frame. The fore cap has an upper surface that is continuous with the upper surface of the lower frame body while closing the end surfaces of both ends in the length direction of the attachment.

An attachment for guiding the wheel of the wheelchair between the rail of the lower frame and the floor surface of the outdoor is directly connected with the lower frame main body.
Alternatively, the attachment is restrained by the vertical frame by indirectly abutting against the prospective piece of the vertical frame via the small cap, so that the problem of deformation of the end does not occur.

[0010] The upper end of the rail of the lower frame is aligned with the level of the indoor floor to eliminate a step between the rail and the indoor floor.
In addition, a step is provided between the upper surface of the lower frame and the outdoor floor surface so that water does not collect on the upper surface of the lower frame, and the lower frame is arranged so that the upper surface thereof is not positioned below the outdoor floor surface. You.

[0011] In the case of the second aspect, water or dust existing on the lower frame is discharged outside the room by the small cap attached to the attachment.

[0012] As described above, the fore cap discharges water and dust on the lower frame body to the outside through the upper surface of the fore cap regardless of the inclined surface of the attachment because the upper surface is continuous with the upper surface of the lower frame body.

Water and dust existing on the lower frame move to both ends in the longitudinal direction through the upper surface of the lower frame and are discharged from the upper surface of the fore cap, so that there is no need to treat on or below the lower frame.
