Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a structure of a shutter attached to a doorway of a residential building, a window, etc., and in particular, a seat plate provided under a shutter curtain has an opening. The present invention relates to a lower structure of a shutter that is regulated so as not to come into close contact with the floor surface.

[Prior Art] Conventionally, ascending / descending shutters are, for example, shown in FIGS.
Like the window shutter shown, the shutter curtain 1
Is a series of slats 11 and the upper shutter case 2,
A shutter S is formed on the outer surface of the frame member 5 of the opening 4 by integrally framed the lifting guide rail assemblies 3 and 3 on both sides. The guide rail assembly 3 has a mounting base frame 31.
And a guide rail 32.

In such a lower structure of the shutter S, the seat plate 6 is connected as a bottom slat along the lower edge of the shutter curtain 1, while the drainer 7 has a receiving groove 71 formed at the front edge, and the upper surface thereof is formed. The seat plate 6 receives the lower end. Reference numeral 72 is a cap for closing the end of the water drain 7, and 73 is a small hole for draining water in the receiving groove 71.

In the example of the shutter shown in FIG. 9, the seat plate 6 is connected as a bottom slat along the lower edge of the shutter curtain 1, and the flange is inclined forward to form the contact portion 61, while the opening portion is formed. An ordinary drainer 7 that tilts forward is formed in the lower part of the shutter 4, and when the shutter curtain 1 is lowered, the two are brought into close contact with each other to close the opening 4. Further, as shown in FIG. 10, the contact portion 61 is formed of a seat plate rubber as a ridge 8 formed so as to be fixed to the lower surface of the seat plate 6 in the longitudinal direction and to be in close contact with the upper surface of the drainer 7. can do. In the above two examples, the contact portion 61 is always the seat plate 6
The shutter curtain 1 and the water drain 7 are brought into close contact with each other continuously in the longitudinal direction of, and the opening 4 is completely closed.

[Problems to be solved by the invention] However, when the shutter S is installed outside the building, rainwater may flow down the curtain surface when the shutter S is closed,
Since snowfall accumulates and stays between the drainage upper surface, it freezes at night or in the winter to solidify the two in close contact. In particular, in the example of FIG. 7, the retention of water in the receiving groove 71 is avoided. Not be
Further, in the example of FIG. 10, the protrusion 8 on the upper surface of the water drainer 7 causes a great tendency of freezing, which becomes an obstacle when starting the operation of raising and releasing the shutter, and it not only takes time to melt but also the driving portion. There was a defect that caused the breakdown of the.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention particularly relates to a shutter for restricting a mutual distance between a seat plate provided in a lower portion of a shutter curtain and a drainer on a lower side of an opening. In the shutter designed to open and close the opening by moving the shutter curtain up and down, the floor surface in the groove of the left and right guide rails that guide the shutter curtain up or down, or the groove. When the projections are formed at both ends of the lower surface of the seat curtain of the shutter curtain located inside, and when the shutter curtain is fully closed, a space for freezing prevention over the entire opening width is provided between the lower surface of the seat plate and the floor surface. It is an object of the present invention to provide a lower structure of a shutter characterized by being configured to be formed, and to disclose means for forming a gap. As a result, it is possible to prevent freezing and sticking between the floor curtain or the water drain and the shutter curtain with a slight modification of the window shutter. Of course, it can be applied to a conventional type shutter or an existing shutter.

[Embodiment] The configuration of the present invention will be described with reference to FIGS. 1 to 4 showing a window shutter as a preferred embodiment. The reference numerals in the drawings for explaining the conventional art are common to the corresponding portions.

In the figure, a seat plate 6 formed as a bottom slat is attached to the lower end of the shutter curtain 1, and protrudes at both ends of the receiving groove 71 of the drainer 7 at the upper surface portion located inside the groove 33 of the guide rail 32. When the parts 10, 10 are formed and the shutter curtain 1 descends to close the opening 4,
Before the lower surface of the seat plate 6 abuts and fits on the bottom surface of the receiving groove 71 of the water drain 7 that constitutes the front edge of the window frame member 5, the lower surface of the seat plate 6 abuts on the upper surface of the projecting portion 10 and the seat plate 6 and the receiving groove 71. A space portion 20 is left over the entire length of the opening width between and. The shape of the protrusion 10 may be a block body merely as a spacer, or may be formed as a downward U-shaped base so as to straddle the water drainage hole 73.

FIG. 5 shows another example of the shutter, and the projection 10 is formed by drawing so that both ends of the drainer 7 are projected into the groove 33 on the upper surface of the part incorporated below the guide rail 32. It is stamped and formed.

As shown in FIG. 6, the formation of the space portion 20 is performed by the protrusion 10
May be formed on both ends of the lower surface of the seat plate 6, or may be formed separately from a small body made of rubber or synthetic resin and fixed. Also in this case, it is desirable that the protrusion 10 be mounted in the groove 33 of the guide rail 3.

Further, in the above embodiment, the protrusion 10 is formed on the lower surface of the seat plate 6 or the upper surface of the drainer 7, but in other embodiments,
In the groove 33 of the guide rail 32, a separate block body can be formed horizontally so as to project from the vertical portion 34.

Obstacle detecting means can be provided on the lower surface of the seat plate 6, and in any of the above-described types, the protruding height of the protruding portion 10 is
A space 20 is secured between the seat plate 6 and the water drain 7 by making the height higher than the height of the seat plate switch which constitutes a part of the detection means.

In forming the space 20 by these protrusions 10,
Practically, it is desirable to form a flange 62 in front of the seat plate 6 to prevent rainwater and the like from entering the inside.

[Operation] In the shutter S configured as described above, it is usual that the shutter curtain 1 is moved up and down and opened and closed by the drive device in the shutter case 2. In the present invention, since the protrusion 10 is formed by being fixedly attached to the lower surface of the seat plate 6 or the upper surface of the drain 7 or the vertical portion 34 of the guide rail 32, the protrusion 10 is formed when the shutter curtain 1 is closed. , Serves as a spacer interposed between the lower surface of the seat plate 6 and the upper surface of the water drain 7, and forms a space portion 20 below the seat plate 6 over the entire opening width so that the seat plate 6 does not adhere to the water drain 7. At this time, the protruding portion 10 is
Since the shutter curtain 1 is formed in the groove 33 and supports the shutter curtain 1 in a small area, the space portion 20 is formed over the entire opening width of the seat plate 6, and therefore both of them are frozen due to the presence of rainwater or snow even in cold weather. The shutter S can be opened and closed without any trouble. Moreover, since the projecting portion 10 is formed by squeezing on the upper surface of the water drain 7 or mounted on the lower surface of the seat plate 6 or in the guide rail 32, there is no obstacle to drainage of the water drain 7 or leakage of water.

[Advantages of the Invention] In summary, the present invention relates to a shutter in which an opening is opened and closed by moving a shutter curtain up and down, a floor surface in a groove of left and right guide rails for guiding the shutter curtain up and down, or the groove When the projections are formed at both ends of the lower surface of the seat curtain of the shutter curtain located inside, and when the shutter curtain is fully closed, a space for freezing prevention over the entire opening width is provided between the lower surface of the seat plate and the floor surface. Since it is configured to be formed, it has an extremely simple structure, but even if there is rain or snow when the shutter is closed,
Due to the freezing caused by the condensation, troubles such as the lower end surface of the shutter closely adhering to the drain surface or the floor surface can be completely eliminated, and smooth opening and closing operation of the shutter can be secured.

Since the protrusion is provided in the groove of the guide rail, it does not spoil the aesthetics, and when driving the shutter curtain up and down, only the protrusion is used for landing, so there is no need for a special configuration. It is possible to reduce the impact sound at the time.

And so on, which have extremely useful practical effects.
