Description

[Detailed description of the invention] The present invention relates to a window frame having a hollow box-like cross section and having a shoji rail on the upper surface, and in particular, the upper surface of the lower frame is provided with an opening having the entire longitudinal length, and the longitudinal length of the opening is This relates to a window sill that has a removably attached blocking plate that closes the entire length, and a through hole is drilled in approximately half of the blocking plate located on the outside of the room.It prevents as much trash as possible on the blocking plate and only drains rainwater. To provide a window lower frame which prevents rainwater from entering a room by allowing rainwater to pass through a through hole into the lower frame and draining it outdoors from a drain port.

An embodiment according to the present invention is shown in Figs. 1 to 4 below.
This will be explained in detail based on the drawings. FIG. 1 is a front view of a sliding window according to the present invention, in which inner and outer shoji screens 3 and 4 are built into a window frame constituted by an upper frame 1, vertical frames 5 and 5, and a lower frame 2.

As shown in FIG. 2, the inner shoji 3 is composed of an upper stile 31, a lower stile 32, a gasket 34 that maintains watertightness between the glass 33 and the stile 31, 32, and a door roller 37 attached to the lower stile 32. The outer shoji 4 also has an upper stile 41, a lower stile 42, a glass 43, and the stile 41,
42, and a door roller 47 attached to the lower stile 42.

On the other hand, the upper frame 1 has a fitting groove 11, and airtight mohair 12 is attached only to the joining part of the fitting groove 11 to maintain the airtightness of the joining part of the shoji.

Further, the lower frame 2 has a hollow box-like cross section and is composed of an outer rail 21, an inner rail 22, a closing plate 23, an opening 24, a drain port 26, and the like.

The lower frame 2 is provided with an opening 24 having a full longitudinal length that opens upward between the inner and outer rails 21 and 22, and when the lower frame 2 is erected, the longitudinal direction of the opening 24 should be appropriately closed in advance. A plate 23 is detachably attached. This closing plate 23 has a through hole 23b bored in approximately the half located on the outdoor side to block dust as much as possible and drain only rainwater.

Further, the closing plate 23 has engaging convex portions 23a and 2 at both ends.
3a, and is removably engaged with the engagement recesses 23a', 23a' of the lower frame 2. Incidentally, the relationship between the convex portion 23a and the concave portion 23a' may be reversed.

Furthermore, the present invention has a predetermined number of transparent holes approximately the same length as the inner shoji in the closing plate 23 that closes the opening 24 of the lower frame 2, as shown in the right half of FIG. A hole 23b is bored. This through hole 23
b may be of a size and number such that the hollow interior of the lower frame and the outside air are in an equal pressure state.

In the above embodiment, the through hole 23b is an elliptical hole, but it may be a square hole, and its shape is not limited.

A predetermined number of drainage ports 26 are provided in the longitudinal direction of the outer surface of the lower frame, so that rainwater that has entered the lower frame can be quickly discharged to the outside. In addition,
At the joining part of the lower frame 2 and on the upper surface of the closing plate 23,
An airtight block 27 is attached to maintain the airtightness of the lower part of the joining frame 35, 45 of each inner and outer shoji 3, 4, thereby preventing rainwater etc. from flowing into the room.

In the vicinity of the doorstop of the inner shoji 3, there is a stile 3.
A stopper 28 is installed to prevent damage to the crescent lock (not shown) provided at 5.

On the other hand, in the outer shoji 4, the long and short inner and outer flanges 42a and 42b of the lower frame 42 straddle the outer rail 21 of the lower frame 2, and the dimension A of the long inner flange 42a is the fit between the upper frame 41 and the upper frame. Since the dimension B between the groove 11 and the bottom surface of the groove 11 is longer than the dimension B, and the dimension B between the upper stile 41 and the fitting groove 11 is longer than the dimension of the outer flange 42b, the outer shoji 4 can be removed only on the indoor side. Can not.

To remove the outer shoji 4 from the indoor side, remove the outer shoji 4 until the upper stile 41 comes into contact with the bottom of the fitting groove 11.
The lower stile 4 is lifted up using the upper stile 41 that it touched as a fulcrum.
2 can be easily removed by rotating it counterclockwise as shown in Figure 2. Furthermore, the lengths of the upper rails 13, 13 of the upper frame 1 are the same.

Incidentally, if the closing plate 23 is molded integrally with the airtight block 27, it will be convenient to attach and detach it.

As explained in detail above, the present invention has inner and outer shoji rails on the upper surface, and an opening with the entire longitudinal length that opens upward between the inner and outer rails, and the longitudinal direction of the opening should be appropriately closed. This window frame has a removable blocking plate attached and a through hole is drilled in approximately half of the blocking plate located indoors and outdoors, so it prevents dust from entering the bottom frame as much as possible on the blocking plate. Even if garbage accumulates, the blocking plate can be easily removed and cleaned, so the drain port will not be clogged, and rainwater that constantly falls into the bottom frame can be efficiently drained, which has practical effects. play.
