DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a cover member, which covers an upper opening of a drain groove provided outside a room, and a height of a floor surface on the indoor side substantially coincides with each other. More particularly, the present invention relates to a lower frame structure of an entrance sash having high watertightness and covering the upper part of the guide rail with a covering member.

[0002]

2. Description of the Related Art As a lower frame structure of a conventional entrance sash,
There is one disclosed in JP-A-7-305569.
In this method, a lower frame is provided at the lower part of the entrance, and a longitudinal gap is provided between the lower frame and a through-hole cover member for covering a drainage groove provided outside the entrance along the lower frame, so that rainwater can pass through the hole. Even if the water flows along the upper surface of the lid member and flows toward the lower frame, the water is drained from the gap to prevent water from entering the inside of the doorway, thereby increasing watertightness. Further, the upper surface of the through-hole lid member, the upper edge of the guide rail (running portion) of the sliding door and the screen door, the upper end of the indoor-side rising wall of the lower frame, and the floor surface of the entrance and exit are formed to be flush with each other. Part was lost. In this way, even a weak person such as a sick person, a physically handicapped person, an elderly person, and a wheelchair can be moved smoothly.

FIG. 10 shows an arrangement proposed by the present applicant (Japanese Patent Application No. 6-315679). This corresponds to the indoor rising wall 18 of the lower frame 8 provided below the entrance.
An upper end is provided at substantially the same height as the floor surface 10 and the lid member 20, and a cover member 52 above the lower frame 8 and closing the lid member 20 and the floor surface 10 at the same height is hinged to the lid member support frame 50. 51 was provided so as to be swingable. The position of the cover member 52 is switched between the closing position A and the retreat position B by the switching mechanism 53,
When the shoji is closed, one end of the swing lever 54 of the switching mechanism 53 and the engaging member 55 of the shoji 14 are engaged by the closing movement of the shoji, and the other end of the swing lever 54 is pushed up.
The cover member 52 is pushed up by the engagement of the other end of the cover member 52 with the cover member 52 and moves to the retreat position B, and the shoji screen 14 is moved to the lower wall 19.
When the sash 14 is opened by moving on the guide rail 15 extended to the other end, the other end of the swing lever 54 and the cover member 52 are disengaged, and the cover member 52 is positioned at the closing position A by its own weight. The space between the lid member 20 and the floor 10 on the indoor side is closed and flattened, so that a wheelchair or the like can smoothly move back and forth.

[0004]

In the above prior art, the upper end of the indoor-side rising wall of the lower frame, the upper edge of the guide rail, the through-hole cover member, and the floor of the entrance are provided at the same height. Therefore, the connecting piece (lower wall) of the lower frame that raises the guide rail whose rising height is reduced due to strength problems
The head difference (height from the connecting piece to the horizontal mounting piece) of the rising wall that rises from the inside of the room is low, and the rainwater that collects between the guide rail of the shoji and the connecting piece crosses the rising wall due to wind pressure, etc. There was a problem that it easily entered the floor.
Further, there is a problem that the front wheel of the wheelchair fits between the indoor side rising wall and the guide rail, between the guide rails of the shoji, and the like. Further, in the technology, the movement of a wheelchair or the like is smoothed by closing the cover member and the indoor side floor surface with a cover member, but a switching mechanism is used to switch the position of the cover member, and the switching mechanism is used. There was a problem that the structure was complicated. In addition, when the cover member is at the retracted position, it is conceivable that foreign matter enters from the longitudinal direction of the lower frame. There was a problem that it could not move and did not close the gap between the lid member and the floor on the indoor side.

[0005]

In order to solve the above problems, according to the present invention, the floor surface of the entrance, the upper surface of the lid member, and the upper end of the indoor-side rising wall of the lower frame are made substantially coincident with each other to cover the sliding door. This covering member covers the upper part of the guide rail of the lower frame corresponding to the opening part opened at the time of opening the shoji, so that the upper surface thereof is substantially the same height as the floor surface and the upper surface of the lid member,
When the shoji is closed, the cover member is accommodated in a storage portion provided outside the opening of the sash in the shoji closing direction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a lower frame structure of a sash provided between a cover member for covering an upper opening of a drain groove provided outside a room and a floor surface on the room side. The lower frame is provided below the entrance opening so that it substantially matches the indoor floor, and the sliding door covers the upper part of the guide rail of the lower frame corresponding to the opening that was opened when the sliding door was opened, and the upper surface was the floor surface. A cover member that connects the upper surface of the lid member is connected, and a storage portion for storing the cover member when the shoji is closed is provided outside the opening that is opened and closed by the shoji in the shoji closing direction. With the lower frame structure of the entrance sash configured as described above, the cover member is securely opened when the shoji is opened, compared to the prior art in which the closing member on the frame side swings by the shoji opening / closing operation. The upper part of the guide rail of the lower frame corresponding to the opening part is covered, and the upper surface of the covering member, the upper surface of the grating, and the height position of the floor surface coincide with each other. Can smoothly move indoors and outdoors. Furthermore, since the storage portion is provided outside the closing direction of the shoji and the cover member is housed in the storage portion when the shoji is closed, no foreign matter enters between the cover member and the lower frame at the time of closing the shoji as in the conventional case, The operation of the covering member is not hindered.

[0007] A guide rail for a cover member, which is continuous with the guide rail of the lower frame and in which wheels provided on the cover member roll, extends in the storage section. The operation of the cover member is smoothed by the wheels and the guide rails provided on the cover member.

Further, the covering member may have a structure in which a plurality of covering member elements extend and contract in the direction of opening and closing the shoji. The covering member can be shortened by making the covering member expand and contract, and even if the storage portion cannot be sufficiently removed. It is suitable because it can be stored in a short storage section.

[0009] Further, the storage section is formed to have a slope that becomes lower toward the shoji to discharge water, or is opened toward the drain groove, so that even if rainwater or the like enters the storage section, the storage section transmits the slope. Since it is discharged, rust and erosion due to water can be prevented.

Further, the cover member is configured to be swingable or movable in the vertical direction at a portion where the cover member is attached to the shoji so as to be inclined or moved up and down along the inclination of the storage section. With this configuration, even if the storage section is inclined as described above, the cover member can move in accordance with the inclination, and the operation of the entrance sash is smooth.
