Description

[Detailed Description of the Invention] This invention relates to storm shutters, and in particular to storm shutters that open and close by rotating around their upper edges, such as eaves shutters.

This type of storm door has a pivot part such as a hinge on the upper edge, and wind and rain that blows on the door plate will be spread along the surface of the door plate, and there is a risk that rainwater will infiltrate through the pivot part. Ta.

In view of the above points, this invention was developed by forming a drain plate close to the upper edge of the door plate on both the door plate side and the building side to which the door plate is pivoted. The purpose of this is to prevent rainwater from entering at the pivot joint of a shutter that rotates around its upper edge to open and close.

Next, an embodiment in which this invention is applied to an eaves shutter will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a door plate of an eaves shutter, and this door plate 1 can be opened and closed vertically within a frame 3 attached to the outer periphery of a window 2.

This door plate 1 is divided into two parts, upper and lower, and the upper door plate 1a located at the upper part and the lower door plate 1b located at the lower part are connected to each other by a hinge 4.

Further, the upper end of the upper door plate 1a is pivotally connected to the upper frame 3a of the frame body 3 by a hinge 5, and a pulley mounting block 6 is pivotally connected to the lower end of the lower door plate 1b by a hinge 7.

This pulley mounting block 6 has a substantially square prism shape with a length equivalent to the lower end side of the lower door plate 1b, and a buffer sealing material 8 made of a flexible material is attached to the lower end surface, and a buffer sealing material 8 made of a flexible material is attached to the lower end surface. As shown in FIG. 5, two pulleys 9a and 9b are attached to the upper and lower sides, respectively.

Among these two pulleys 9a*9b, the pulley 9a attached to the upper part is attached via an extension plate 10 extending above the pulley attachment block 6.
One end of a hoisting wire 11 connected to a hoisting device such as a spiral leaf spring (not shown) is fixed to the hoisting wire 11 .

The pulleys 9a and 9b are loosely fitted into a guide rail 12 formed on the frame 3, and are movable up and down.

Further, a convex portion 13a is formed continuously on the left and right sides on the upper surface of the pulley mounting block 6, and a sealing material 14a made of neoprene sponge rubber material or the like is pasted on the lower end surface of the lower door plate 1b corresponding to this convex portion 13a. It is worn.

Similarly, a sealing material 14b is attached to the upper end surface of the lower door plate 1b, a protrusion 13b is formed on the lower end surface of the upper door plate 1a corresponding to this sealing material 14b, and a protrusion 13c is formed on the upper end surface of the upper door plate 1a. A sealing material 14c is formed on the lower surface of the upper part 3a corresponding to the convex part 13c.

The upper frame portion 3a is fixed to the outer circumferential portion 16 of the window of the building with mounting screws 15, and the upper frame portion 3a has a screw thread near the pivot point with the upper door plate 1a, that is, near the hinge 5. A fixed drain plate 17 that covers the number 5 is formed to protrude downward.

Furthermore, a rotary drain plate 18 is formed inwardly of the fixed drain plate 17 adjacent to the screw 5 on the upper surface side of the upper door plate 1a, and projects upwardly.
a flat plate portion 18a held substantially at right angles to a; and a curved plate portion 18b formed between the flat plate portion 18a and the upper door plate 1a.
It is made up of.

The curved plate portion 18b is bent so as to coincide with a part of a circle having the center of rotation of the hinge 5 as the center thereof, and covers a part of the outer periphery of the hinge 5.

The flat plate portion 18a has a width that substantially matches the lower edge of the fixed drain plate 17 when the door plate 1 is closed.

On the other hand, a drain gutter 20 is formed on the inner surface 19 of the lower door plate 1b, that is, the surface on the indoor side, and the drain gutter 20 has a plate body formed protruding from the inner surface 19 in the upper direction of the lower door plate 1b. It is bent into an L-shape, and is provided continuously on the left and right sides of the lower door plate 1b. In this embodiment, the drain gutter 20 is provided at both the upper and lower positions of the lower door plate 1b. It is set in.

Further, side plates 22 and 23 are attached to both side edges of the door plate 1 to cover the gap 21 between the upper door plate 1a and the lower door plate 1b that is created when the door plate 1 is folded.
Contact portions 22a and 23a formed by bending the end edges into an L-shape are formed on the opposing end edges of 2 and 23, respectively.
The edge on the other end side is fitted and fixed into side plate fitting grooves 24 and 25 formed in the upper door plate 1a and the lower door plate 1b, respectively.

As shown in FIG. 7, each of the side panels 22 and 23 is formed by removing unnecessary portions 26a and 26a of the rectangular plates 26 and 26 according to the size of the door panel 1 or the size of the window to be installed. It is formed.

On the other hand, a rail unit 27 is removably fitted inside the frame 3, and each rail 2B, 29.30
Glass doors 31 and 32 and a screen door 33 are respectively fitted into the windows.

The operation of the eave shutter with the above configuration will be explained below.

When the door plate 1 is pulled down from the folded state, the pulley mounting block 6 is guided by the guide rail 12 and descends, and at this time, the weight of the door plate 1 is transferred via the pulley mounting block 6 to the pulley 9a.

9b, and the pulleys 9a and 9b are connected to the guide rail 12.
The vehicle is lowered while being pressed toward the rear of the vehicle, that is, toward the indoor side, but the force is dispersed between the two upper and lower pulleys 9a and 9b, resulting in smooth movement of the pulleys.

In this lowered state of the door plate 1, the lower door plate 1b gradually slopes from the horizontal state, and if rainwater is collected on the inner surface 19 of the lower door plate 1b, the rainwater flows toward the indoor side when the door plate 1 is tilted. However, the rainwater is stopped by the drain gutter 20 and flows to the side of the door panel 1, thereby preventing rainwater from flowing into the room.

Furthermore, when the door plate 1 is tilted and becomes an upright state, the lower door plate 1b
The lower end of the block rotates around the hinge 7 until the end, but since the pulley mounting block 6 is always moving up and down, the lower end surface of the pulley mounting block 6 does not rub against the frame 3, and the pulley mounting block 6 does not rub against the frame 3. It comes into contact with the body 3 in a sealed manner.

When wind and rain blows on the door plate 1 that is in an upright state in this way, the wind and rain spreads along the surface of the door plate 1 and tries to enter the interior of the room through the respective pivot parts and the abutting parts at the lower end.
The contact between the convex portion 13 formed at each pivot portion and the sealing material 14 prevents the infiltration of wind and rain.

Furthermore, the wind and rain diffused along the surface of the door plate 1 are rewound by the rotary drain plate near the upper edge of the door plate 1, and the lower edge of the door plate 1 is in close contact with the pulley mounting block 6 and the frame 3. Since there are no gaps between the walls, the infiltration of wind and rain is more reliably prevented.

In addition, if it rains when the door plate 1 is raised and folded, the rain tends to enter the interior of the room through the pivot joint on the upper edge of the door plate 1, but the rotary drain plate 18 blocks the flow of rainwater, preventing rainwater from entering the indoor side.

On the other hand, when the door plate 1 is folded, the side plates 21 and 22, which prevent wind and rain from entering the inside of the door plate 1 from the sides, are manufactured in a rectangular shape separately from the door plate 1. Since the unnecessary parts 26a*26a are cut out and used depending on the size of the window or the size of the window to be installed, the side plates 21 and 22 can be easily adapted to windows of various sizes. There is.

The eaves shutter according to the present invention can also be formed into a substantially inverted W shape with two intermediate door panels interposed in a pivoted manner between the upper door panel 1a and the lower door panel 1b.

As explained above, according to this invention, in the vertically movable storm door, the door plate 1a is formed with a rotating drain plate 18 projecting upward so as to cover the upper edge pivot portion of the door plate 1a. On the other hand, a stationary drain plate 17 is formed protruding downward so as to cover the outside of the rotary drain plate 18 on the immovable part of the building to which the door plate 1a is pivotally attached. In both the substantially vertically closed state and the substantially horizontally opened state, wind and rain blown onto the outer surface of the door plate and diffused are prevented from entering the pivot portion by the rotary drain plate 18 which is integrated with the door plate.

Further, rain water from the gap between the upper edge of the rotary drain plate 18 and the wall surface of the immovable part on the building side is drained by a fixed drain plate 17 formed on the outside of the rotary drain plate 18 and protruding in the opposite direction. It is blocked and discharged to the outside of the rotary draining plate 1B.

Therefore, according to this invention, even when the wind and rain are strong, rainwater is almost certainly prevented from entering the pivot joint on the upper edge of the door plate in vertically movable shutters, and rainwater from the pivot joint is prevented from entering the room. This has the effect of reliably preventing infiltration and corrosion of the pivot joint due to rainwater.
