Description

[Detailed description of the invention] This invention relates to an opening frame on which sliding windows, sliding doors, etc. are installed.

Conventionally, as shown in FIG. 4, opening frames in which sliding windows and sliding doors are installed do not form a flow path for condensed water.

During humid seasons such as winter and the rainy season, or when a bathroom is installed indoors, condensation water collects on the earthen walls near the indoor side of the kamiazusa and drips down, causing the tatami mats inside the room to become wet. The current situation was that it was seeping into the window sill where the bottom frame was attached.

The above phenomenon is particularly noticeable when a bathroom is provided indoors.

In addition, the influence of condensed water that drips down even in buildings made of reinforced steel is significant, causing the corrosion of structural materials to accelerate.

In this way, the inventor repeatedly created a condensed water flow path in order to address the above-mentioned conventional problems, and formed a flow path for the condensed water in the opening frame, so that the condensed water inside the room can be smoothly discharged to the outside, and the condensed water can be transferred to the indoor structural materials. We proposed an opening frame that prevents water from seeping in.

This invention will be explained below based on embodiments shown in the drawings.

First, an overhang portion 3 is provided at the indoor end portion 2 of the upper frame 1a constituting the opening frame 1.

The projecting portion 3 is provided so as to protrude 7 downward from the indoor end portion 2.

The upper frame 1a is provided continuously in the longitudinal direction of the upper frame 1a.

A horizontal concave groove 4 is provided at the tip of the projecting portion 3.

This horizontal groove 4 has discharge ports 6 at both ends 5 in the longitudinal direction.

As shown in FIG.
It is desirable to form a notch of about 2 mm.

However, the discharge port 6 may be formed by providing through holes (not shown) at both ends 5 of the horizontal groove 4.

By the way, in FIG. 3, a horizontal groove 4 is provided at the tip of the overhanging portion 3, on the outdoor side.

In order to drain the condensed water 7 into the horizontal groove 4, a protrusion 8 is provided at the tip of the overhang 3 and protrudes toward the indoor side with an upward slope, and between the protrusion 8 and the horizontal groove In order to connect
A long hole 9 is provided in the projecting portion 3.

Incidentally, both ends 5 of the lateral groove 4 shown in FIG. 3 also have discharge ports 6 as in the case shown in FIG. 2.

In the above description, the horizontal groove 4 is positioned as a flow path for the condensed water 7.

Next, on the indoor side surface 10 of the overhanging part 3, a flange 1 is attached extending from the overhanging part 3 to the structural material lintel 11.
2 is a protruding type.

The flange 12 has an upward slope extending from the overhanging portion 3 to the lintel 11.

Note that the upward slope is preferably about 10 degrees.

Thus, this idea consists of the above structure.

Next, the state of use of this invention will be explained.

Indoors, condensed water 7 adhering to the surface of the flange 12
is the surface of the flange 12, and the interior side surface 10 of the overhanging portion 3.
and accumulates in the horizontal concave groove 4.

This accumulated condensed water 7 flows from the discharge port 6 through the indoor side wall of the vertical frame 13 to the surface of the lower frame 14, and is finally discharged to the outside.

Note that the outflow route of the condensed water 7 is as shown in FIG.

Although not shown, the connecting portion of the rail 15 provided on the upper surface of the lower frame 14 with the vertical frame 13 is cut out by about 20 to 3 Q mm, and the cutout is formed as an outflow path.

Thus, this invention consists of the above, and according to the opening frame with a flow path for condensed water according to this invention, the condensed water adhering to the surface of the flange in the room flows into the horizontal groove along the slope of the flange, and further the condensed water flows. Since it is discharged outside through the channel, condensed water does not seep into structural materials such as lintels and window sills.

This is particularly advantageous for buildings made of reinforced steel.

Therefore, the practical value of this idea is extremely large.
