Abstract

PROBLEM TO BE SOLVED: To improve the water-tightness and appearance by providing a gutter- like part formed between two rails with a lid disposed with such a little clearance as to permit inflow of rainwater in such a manner as to freely open and close, thereby covering a drain hole provided between the rails. SOLUTION: Rainwater which sweeps to a window from the outdoors passes through a drain hole 7 provided in a gutter-like part 6 of a flat lower frame 1, drops into the hollow interior of the lower frame 1 to flow down the bottom of a partition wall 8, and is discharged to the outdoors through a drain hole 11 provided in a lid plate 10. When rainwater is thrown up through the hole 11 by strong wind, a lid 15 prevents entering of rainwater. In the case of cleaning the gutter 6, after a sash is moved, one end of the lid 15 is turned upward to open the gutter 6, and dust in the gutter is removed. Thus, water-tightness can be improved, and as the drain hole is covered, the appearance can be improved, and dust between the rails can be easily cleared away.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage mechanism for a lower frame of a window sash, and more particularly, to prevent rainwater from being blown up from a drain hole.

[0002]

2. Description of the Related Art As a conventional drainage mechanism for a lower frame of a window sash, for example, as shown in Japanese Utility Model Laid-Open No. 6-62180,
Drain holes are provided in the center of the surface of the lower frame and on the inside of the surface of the lower frame, etc., so that rainwater can be discharged to the outside of the room through the drainage fittings provided outside the outdoor side of the lower frame. It is known to have been made.

[0003]

In the drainage mechanism of the lower frame, the drainage hole is formed in the surface of the lower frame, and the rainwater is drained through the extraction metal fitting provided outside the outdoor side. However, when there is a strong wind, wind may blow from the extraction fittings and rainwater may be blown up from the water drain hole, and the water drain hole drilled on the surface of the lower frame can be seen as it is, resulting in poor design. Was. Therefore, an object of the present invention is to solve the above problems and to provide a drainage mechanism for a lower frame of a window sash that has a good appearance while suppressing the blowing up of rainwater from the drain hole.

[0004]

In order to achieve the above object, the present invention provides a water drain hole between two rails provided on the upper surface of the lower frame of a window sash, the outer rail and the outer rail. In the drainage mechanism of the lower frame of the window sash, which also has a drainage hole in the lower portion of the side surface of the lower frame to discharge the invading rainwater to the outside through the drainage hole, between the two rails. It is configured to cover the drain holes provided between the rails, and at a slight interval so that rain water can flow in, with a lid that can be opened and closed to prevent the rain water from blowing up from the drain holes. It was done.

Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 shows an example in which the drainage mechanism of the present invention is applied to a flat lower frame of a sliding window, and shows a vertical cross section of its main part, and FIG. 2 shows a cross section thereof. The sliding window shown in FIG. 1 is a window sash frame in which an upper frame, a lower frame, and left and right vertical frames are combined in a square shape, and two shoji screens are installed in a sliding shape. A flat lower frame 1 in which the partition plates 3 and 3 and the rails 4 and 5 on the indoor and outdoor sides are configured to have the same height so that a wheelchair or the like can easily enter and exit on the lower frame. Has become. The flat lower frame 1 is formed in a hollow shape, and on its upper surface 2, partition plates 3 and 3, an external shoji rail 4 and an internal shoji rail 5 are integrally formed. A gutter-shaped portion 6 slightly lower than the upper surface 2 is formed between the external shoji rail 4 and the internal shoji rail 5, and each external shoji on the built-in side of the external shoji and on the built-in side of the internal shoji. As shown in FIG. 2, two long water drainage holes 7 and 19 are provided near the indoor side of the rail 4 for rainwater, and rainwater blown into the window from outside the room is passed through the water drainage holes 7 and 19, respectively. The flat lower frame 1 is designed to be dropped into the hollow interior and discharged outside the room. Further, inside the hollow bottom flat frame 1, a partition wall 8 is provided, the bottom portion of which is inclined outward so that rainwater falling through drainage holes 7 and 19 provided in the gutter-shaped portion 6 can flow to the outdoor side. ing. A lower portion of the flat lower frame 1 is opened on the outdoor side surface 9 in the longitudinal direction, and a receiving groove 12 is formed at the upper end of the opening.
Further, a step portion 14 on the lower surface 13 is arranged at the lower end portion, and the upper and lower end portions of the cover plate 10 are fitted and attached to these. Further, a water draining hole 11 is provided in the lower portion of the lid plate 10 and falls from the water draining holes 7 and 19 provided in the gutter-shaped portion 6 of the upper surface 2 of the flat lower frame 1 and along the bottom portion of the partition wall 8. The rainwater that flows down is discharged to the outside of the room.

The trough-like portion 6 formed between the two rails 4 and 5 of the flat lower frame 1 is formed so as to cover the drainage holes 7 and 19 on both sides of the trough-like portion 6 except for the fitting portion. Shaped lid 1
5, 15 are provided. As shown in FIG. 1, the lid 15 is formed with a tubular rotating portion 16 having a circular cross section at the indoor end, and is fitted to a bearing portion 17 formed at the indoor corner of the gutter-shaped portion 6. The one end can be opened and closed as shown by the dotted line. Further, a leg 18 is provided on the lower surface of the tip of the lid 15 so as not to block the water drain holes 7 and 19 provided at the bottom of the trough-like portion 6 and to prevent passage of a wheelchair or the like. As described above, the flat lower frame 1 is configured so as to be flush with the upper surface 2 of the flat lower frame 1 and to maintain a slight space between the flat lower frame 1 and the bottom of the trough-shaped portion 6. Further, the lid 15 is provided with a gap 2 between the lid 15 and the external shoji rail 4 so as not to block the flow of rainwater.
0 is provided and the leg portion 18 is provided with a cutout portion. When cleaning the gutter-shaped part 6, since one end of the lid 15 is located below the lower frame of the shoji as shown in FIG. 2, after moving the shoji, one end is moved upward as shown by a dotted line in FIG. It can be rotated to remove dust such as dust. In addition, the lid 15 is provided with legs at the front end and the rear end,
It may be attached by screwing it onto the gutter-shaped part 6 from above, and it is possible to suppress the blowing up of rainwater,
Alternatively, the gutter-shaped portion 6 may be cleaned by removing the screw and removing the lid. Although the above has described the example in which the drainage mechanism of the lower frame of the present invention is applied to the flat lower frame of the sliding window, it is also applicable to the flat lower frame of other window sashes such as a pulling window, and the like. The frame can be applied not only to a flat lower frame but also to a lower frame having a normal step and having drain holes between the rails.

[0007]

The present invention has the above-mentioned structure, and
Since a lid configured to be openable and closable is provided between the rails of the book so as to cover the drainage hole provided between the two rails, rainwater is prevented from being blown up from the drainage hole to improve watertightness. The drain hole is hidden and the appearance is good. Since the lid is openable and closable, dust such as sand dust between the rails can be cleaned at appropriate times, and good drainage of rainwater can always be maintained.
