Description

[Detailed description of the invention] This invention relates to a window sill, and in particular to a window sill that prevents rainwater from entering the room through a seal structure of the window sill and simplifies the mounting structure to the frame. It is.

Conventionally, in the structure of this type of window sill, as shown in FIG. 1, an anchor rail 11 having a bent structure 10 is fixed with bolts 12, and then a shoji 13 is attached to the anchor rail 11. 1
4a, 14b, etc. When attaching the lower frame 15 to the anchor rail 11, the draining plate 16 is tightened on the outside with fixing bolts 17, and the anchor rail 11 and the fixing bolt 18 are tightened together. The lower frame 15 is fixed, and the joint between the lower frame 15 and the draining plate 16 and the draining plate 16
Seal portions 19a and 19b were provided between the main body 10 and the main body 10 to prevent rainwater from entering.

However, with the above-mentioned conventional structure, the installation work is time-consuming, and if the seal breaks at the joint between the bottom frame 15 and the drain plate 16, or if a mistake is made in the construction of the seal, rainwater, etc. may enter through the seal portion 19a. This is easy to do, and there are disadvantages such as the base corrodes and rainwater seeps into the interior of the room.

This idea was made to improve the drawbacks of the conventional structure mentioned above, and the structure of the lower frame is integrally formed with the draining plate, making it easier to assemble the anchor rail attached to the frame and the lower frame. The present invention provides a window sill which is characterized by being configured to improve installation workability and prevent rainwater from entering.

Hereinafter, an embodiment according to this invention will be explained in detail based on FIG. 2. Figure 2 is a cross-sectional view of the main parts of this invention, in which 1 is a frame to which a window frame is attached, 1a is an opening surface of this frame 1, 2 is an anchor rail fixed to the frame 1, and 3 is a shoji etc. The anchor rail 2 and the lower frame 3 are each integrally extruded.

The rail 3 on which a shoji etc. is attached to the lower frame 3
a, 3b, etc. are provided, and a draining portion 4 that hangs downward from the opening surface 1a of the frame 1 is integrally provided on the outside of the main body of the lower frame 3.

Further, a hollow portion 5 is provided on the lower surface of the rails 3a, 3b of the lower frame 3 to increase strength.
U-shaped fitting recesses 6a and 6b are integrally formed on the lower surface of the hollow portion 5 and inside the draining portion 4 in the longitudinal direction of the lower frame 3.

Anchor rail 2 to which the above lower frame 3 is attached
is fixed to the frame 1 by fixing bolts 7a, and the lower frame 3 is attached to this anchor rail 2.
A convex portion 8 that is fitted into the U-shaped fitting recesses 6a and 6b.
a and 8b are integrally formed in the longitudinal direction of the anchor rail 2.

Therefore, in order to attach the integrally formed anchor rail 2 and lower frame 3 to the body 1 as described above, first, fix the anchor rail 2 to the body 1 by tightening the fixing bolts 7a.
After fixing, the fitting recesses 6a, 6b of the lower frame 3
The anchor rail 2 is positioned by fitting into the convex parts 8a and 8b of the anchor rail 2, and the anchor rail 2 and the lower frame 3 are fixed with the fixing bolts 7b. A sealing portion 9 is provided between the draining portion 4 and the frame 1, and the installation work is completed.

As explained in detail above, the window sill according to this invention is provided with a draining part that is located on the outside of the shoji frame and hangs down from the frame, and is integrated with the bottom sill, and has an anchor. It has a structure in which all the fitting recesses that fit into the protrusions of the rail are opened toward the indoor side and are provided integrally. Therefore, the structure is simple, and since the lower frame is pushed in from the outdoor side with the anchor rail attached to the frame, the lower part is open, making it extremely easy to form a seal and to perform the installation work. Since there are no exposed areas where rainwater can enter from outside, there is no need to worry about water leaking into the room, and this has practical effects.
