Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an airtight device for a window shutter attached to a window frame such as a sash window.

[Problems to be solved by the conventional technology and invention] Conventionally, as shown in FIG. It was attached to the lower frame a.
Therefore, if you use this product in snowy areas in winter,
There is a drawback that snow accumulates on the drain plate b and the shutter curtain does not close completely. Therefore, as shown in Fig. 6, a receiving member f provided at the bottom of the guide rail c.
The structure is such that the shutter curtain is received by the shutter curtain, and there is no drain plate between the guide rails c and c, and the airtightness between the shutter curtain and the window sill a is as follows.
There is a method in which the free end of the elastic airtight material g protruding from the window sill a is brought into close contact with the seat plate e, but in this case, there is simply an elastic material between the seat plate e and the window sill a. Since only the airtight material g is present, there are drawbacks such as security concerns, which has been a problem.

[Means for Solving the Problems] The present invention has been devised in view of the above-mentioned circumstances with the aim of providing an airtight device for window shutters that can eliminate these drawbacks. The present invention is a window shutter installed on the outside of a window frame installed in a building, in which a bottom cap is provided at the lower end of a guide rail that guides the shutter curtain up and down in the window shutter, and a bottom cap is provided on the upper surface of the bottom cap. The present invention is characterized by being provided with a guide surface that guides the lower edge of the seat plate at the lower end of the shutter curtain at an angle so that it comes into contact with the outer surface of the window sill.

With this configuration, the present invention allows the seat plate to be guided by the bottom cap attached to the lower end of the guide rail to come into contact with the outer surface of the window sill, so that the shutter curtain can be used even during snowy conditions. The purpose of this invention is to make it possible to lower the roof reliably and to have extremely excellent airtightness and security.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawing, 1 is a sash window made of extruded material, which is installed to fit inside the opening of a building.
Guide rails 4, 4 are attached via appropriate mounting members 3, 3, and the upper part of these guide rails 4, 4 is attached to a shutter curtain 6 wound around a winding drum (not shown) inside the shutter case 5. The shutter curtain 6 is raised and lowered along the guide rails 4, 4 in such a manner that a window shutter is formed.

A bottom cap 7 is fitted to the lower end of the guide rail 4, and the upper surface of the bottom cap 7 is a guide surface 7a that is sloped so that it becomes lower towards the indoor side.
The seat plate 6a contacts from above and slides on the guide surface 7a in an inclined manner, so that the lower edge of the seat plate 6a touches the outer surface 9 of the lower frame 9 in the sash window as shown in FIG.
It is configured to be in a closed position in contact with a. On the other hand, 8 is a guide member provided at the lower end of the guide mounting frame 3 so as to face the bottom cap 7, and the guide member 8 has a seat plate 6a between it and the guide surface 7a of the bottom cap 7. Curved guide surfaces 8a are formed at intervals that allow guidance. Furthermore, the bottom cap 7 is provided with a plurality of through holes 7b in the vertical direction, through which snow and the like can fall and be discharged.

In the embodiment of the present invention constructed as described above, the shutter curtain 6 is now connected to the guide rail 4.
When the seat plate 6a comes into contact with the guide surface 7a of the bottom cap 7, the seat plate 6a contacts the guide surface 7a of the bottom cap 7.
a is inclined while the lower end is the outer surface 9a of the window lower frame 9
The window will be closed in contact with the

In this way, in the present invention, the bottom cap 7 is provided at the bottom of the guide rail 4, thereby eliminating the need for a conventional drain plate, and making it possible to reliably close the shutter even when it snows. However, in this closed state, the seat plate 6 is tilted.
a is in contact with the outer surface 9a of the window sill 9, so it is possible to provide airtightness by providing an elastic airtight material on the window sill 9, such as one in which the seat board descends vertically. No consideration is required at all. Moreover, since there is no gap at all between the window lower frame 9 and the seat plate 6a, it is possible to achieve an extremely excellent security feature.

Furthermore, due to the presence of the guide member 8, the seat plate 6
The inclination of the seat plate a becomes even more reliable, and even if the inclined seat plate 6a is lifted upward, it cannot be lifted because of the guide member 8, and therefore the security is further improved. Become. Furthermore, since the bottom cap 7 is provided with the through hole 7b, the surface area of the guide surface 7a of the bottom cap 7 is substantially reduced to the absolute minimum, so that the amount of snow that accumulates is not large enough to be absorbed. Since falling snow is also removed from the through hole 7b, the seat plate 6a can always be guided reliably without being affected by the snow.

[Operations and Effects] In summary, since the present invention is constructed as described above, the shutter curtain can be closed with the lower end of the seat plate in contact with the window sill by the inclined guide of the bottom cap. Therefore, although the structure eliminates the need for a drainage plate so as not to be affected by snow accumulation, the seat plate and the window sill are sealed with no space between them, thereby ensuring airtightness. It is possible to achieve excellent airtightness without separately preparing an elastic airtight material, and also to be extremely excellent in terms of crime prevention.
