Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a drainer for draining rainwater, etc. accumulated between the rails of the lower frame of the sash outside.

(Prior art) In general, when rainwater etc. enters from the outside in a sash, the inside of the sash formed on the upper surface of the sash bottom frame.
Rainwater collects between the rails for the outside shoji. Therefore, in order to drain such water to the outside, drainage holes are formed in the outer rail of the outer shoji screen.

(Problems with the Prior Art) However, if the difference in height between the drainage hole and the water reservoir on the sash bottom frame is small, there is a risk that drainage will not be carried out smoothly through the drainage hole.
For example, when wind and rain blow against the drain hole from the outside, the pressure prevents the draining action, and water accumulates on the lower frame until the water head reaches a level that balances the pressure.

The present invention has been made in view of the above, and an object of the present invention is to provide a satsui drainer that can suitably drain infiltrated water even when external pressure is high.

(Means for solving the problem) The drain of the present invention comes into contact with the outdoor vertical wall of the lower frame of the sash, forming a closed space that communicates with the indoor side through the drainage hole formed in the vertical wall. A main body that
a drain hole formed in the lower part of the main body in order to communicate the closed space with the outdoors at a position below the drain hole; and a drain hole that allows water to move only to the outdoors through the drain hole. and a fixing means for fixing the main body to a predetermined position on the outdoor vertical wall surface of the lower frame.

(Example) Examples of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show the mounting position of the drainer of the embodiment. In the figure, reference numeral 1 denotes an inner and outer sash, and the lower frame 3 of this inner and outer sash 1 has inner and outer rails 3b and 3c for the inner and outer shoji 5 and 7 extending vertically on the inclined bottom wall 3a. ing. Among these, the lower vertical frame 6d that is continuous with the outer rail 3c facing the outdoor side has a horizontal bottom wall 3e whose lower end is bent at right angles to the outdoor side, and the tip of the horizontal bottom wall 3e has an upward direction. Screen door rail 3f installed perpendicular to
is formed. Here, reference numeral 9 denotes a drainer of this embodiment, which is attached to the front surface of the drain hole 3h of the lower frame 3.

3 to 6 show the drain 9. FIG. As shown in the figure, the drain main body 9a has a substantially square shape, and forms a closed space 9b by coming into contact with the vertical wall 3d of the lower frame mentioned above. A rectangular recess 9d is formed on the lower side of the vertical wall 9c of the main body 9a, as shown in FIGS. A mouth 9f is formed. Furthermore, this drainage port 9f has four circumferential vertical walls 9e.
A valve body 9g having a valve seat is rotatably attached to the vertical wall 9c, which is the outdoor side, about its upper end axis. On the other hand, on the upper wall 9h of the main body 9a,
A rib 9i is formed that projects vertically upward, and a stretchable elastic piece 9k that projects diagonally downward and outdoors is formed on the bottom wall 9j of the main body 9a. In addition, protrusions 9n and 9o protruding toward the indoor side are formed on the inner surfaces of both side walls 9l and 9m of the main body 9a.

However, as shown in FIG. 7, a hook portion 3g is formed on the side of the lower frame 3 of the inner and outer sash so that it can be fitted from above the rib 9i, and the outer rail 3c of the lower frame is provided with a hook portion 3g. , a drainage hole 3h is bored, the lower end of which is connected to the inclined bottom wall. Further, the width of the drain hole 3h is set such that the above-mentioned drain protrusions 9n and 9o fit into the inner peripheral side walls thereof.

Therefore, by appropriately determining the length and elasticity of the elastic piece 9k at the lower end of the drainer 9 constructed as described above, the lower frame of the inner and outer sash 1 can be adjusted as shown in FIG. It can be attached to a vertical wall 3d.

In detail, the tip of the elastic piece 9k of the drainer 9 is
The screen rail 3f of the sash lower frame and the inner corner of the flat bottom wall 3e are pressed against each other and curved, the hook portion 3g is fitted from above the rib 9i, and both protrusions 9n and 9o are fitted into the drain hole 3h. As a result, the drainer 9 is fixed in the vertical direction by the upward elastic force of the elastic piece 9k, and is tightly attached to the lower frame vertical wall 3d and the outer rail 3h due to the elastic force of the elastic piece 9k in the indoor direction. By doing so, a closed space 9b is formed.

Furthermore, both protrusions 9n and 9o each have a drainage hole 3h.
Since the drainage device 9 is fitted into both side walls of the drainage device 9, the left and right sides of the drain device 9 are fixed.

In the internal/external sash with the drainer 9 attached in this way, as shown in Fig. 8, the infiltrating water accumulated on the inclined bottom wall of the lower frame is drained from the drain hole 3h of the outer rail into the closed space 9b of the drainer. flows into this closed space 9
It falls downward from inside b and is washed outdoors through a drain port 9f formed at the lower end. As is clear from the figure, the drain outlet 9f of the drainer is located at a step lower than the drain hole, and therefore, even when the outdoor pressure is high, the height difference h Drainage is carried out smoothly by the water head pressure, and a large amount of infiltrated water does not accumulate on the sloped bottom wall. In addition, the valve body 9g is rotatable only toward the outdoor side and has a function as a check valve, so that rainwater and the like will not enter the indoor side from the drain port 9f.

(Effects of the invention) As explained above, since the drain according to the invention has a drainage port below the upper surface of the lower frame of the sash where infiltrated water collects, drainage is effective regardless of the pressure on the outdoor side. This makes it possible to do this smoothly, thereby improving the watertightness of the inner and outer sashes. Furthermore, since the drain port is provided with a valve body that allows water to flow only from the outdoor side, it is possible to reliably prevent rainwater from entering from the outdoor side. Furthermore, the drainer of the present invention has the advantage that it can be easily attached to a predetermined position on the lower frame of the sash.
