DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash structure in which a door slides in and out of a sash frame attached to an outdoor opening of a building, and more particularly to a door in a barrier-free sash in which an upper surface of a lower frame is formed to be substantially flat. The present invention relates to a high watertight structure that has excellent slide opening and closing properties and prevents infiltration of rainwater with wind pressure into a room.

[0002]

2. Description of the Related Art In general, a sash frame is formed in an outdoor opening of a building by upper and lower frames and left and right vertical frames, and a sliding door structure is provided in which a sliding door is slidably opened and closed. In this case, conventionally, as shown in FIG. 8, a sash lower frame is provided with a deep concave portion having a groove also serving as drainage, and a high ridge-shaped rail is protruded into the concave portion. In general, a door wheel attached to a lower frame rotates and moves. Also, a step is provided so that the indoor side is higher between the outdoor sash rails and the indoor sash rails at the outdoor opening of the building, and a step is provided between the outdoor side and the indoor side in the rail groove. To prevent the infiltration of wind and rain. More specifically, rainwater sprayed on glass etc. falls along the shoji and accumulates in the rail groove of the lower frame, especially the combination of outer and inner shoji, and the door frame and sash vertical frame of the shoji. It is easy to stay in the corners of the room, but the wall of the rail groove prevents intrusion into the indoor side, and the accumulated rainwater flows out to the outside by its own weight.

However, a barrier-free type sash structure in which the upper surface of the sash lower frame is formed flat does not have a wall of a rail groove in which the drainage groove is deep, and in an outdoor sash, it becomes 500 Pa in middle and high-rise buildings. In order to prevent a nearby wind pressure or a pressure difference due to the temperature difference between the outside and the room, and to prevent rainwater from entering the room, secure an airtight line between the shoji and the sash frame, and form an airtight line. It was necessary to drain the water immediately from the top of the frame. In addition,
Japanese Utility Model Application Laid-Open No. 3-68285 discloses an example in which the upper surface of the lower frame of the sash (the traveling portion of the sliding shoji) is formed substantially flat. It is a constituent requirement to provide tight materials on both sides. As a result, the opening and closing operation force of the shoji increases due to the resistance of the tight material on both sides, and the outside material is prevented from entering the lower frame recess by the tight material on both sides of the protruding piece, so that the pressure of the outside air and the lower frame Since the pressure difference in the concave part becomes large and it is difficult to stably seal over the entire length of the protruding piece in the longitudinal direction, rainwater flows intensively due to this pressure difference from a weakly sealed part and invades the indoor side. There were technical challenges.

[0004]

The present invention relates to a door which slides on a lower frame surface of a sash composed of upper and lower and left and right vertical frames attached to an outdoor opening of a building. As shown in the construction image of the outdoor lower frame flat sash adopting the high watertight structure according to the invention, as shown in the diagram, the upper surface of the sash lower frame is formed flat, and the sliding property of the door by the conventional ridge rail structure is maintained.
