Description

[Detailed description of the invention] In this invention, the upper edge of the upper door plate is rotatably attached to the upper part of an opening such as a window, and the lower edge of the upper door plate is attached directly or via an intermediate door plate. The upper edge of the door plate is rotatably connected, and the lower edge of the lower door plate is movable up and down along both sides of the opening such as the window, and when the lower door plate is raised, the upper and lower edges of the door plate are connected. This relates to an eaves storm door in which the door panels overlap and protrude like an eave at a position above an opening such as a window, and when the lower door panel is lowered, the upper and lower door panels are continuous in the vertical direction and close the opening.

When this type of eaves shutter is folded, if rainwater enters between the folded door panels, there is a problem that when the door panels are closed, the rainwater will flow down into the room. Ta.

In view of the above points, the purpose of this invention is to prevent rainwater from falling into the room when the door is closed by forming a drain gutter on the inside surface of the door.

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.

Furthermore, the upper end side of the upper door plate 1a is the upper frame portion 3a of the frame body 3.
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 rectangular shape with a length equivalent to the lower end side of the lower door plate 1b, and a buffer sealing material 8 made of flexible pillar material is attached to the lower end surface, and a cushioning seal material 8 made of flexible pillar material is attached to the lower end surface. As shown in Figure 5, there are two pulleys 9 on top and bottom respectively.
a and 9b are attached.

Among these two pulleys 9a and 9b, the pulley 9a attached to the upper part is attached via an extension plate 10 extending above the pulley mounting 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 0 .

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 convex portion 13b is formed on the lower end surface of the upper door plate 1a corresponding to this sealing material 14b, and a convex portion is formed on the -E end surface of the upper door plate 1a. 13C is formed, and a sealing material 14C is formed on the lower surface of the upper frame portion 3a corresponding to the convex portion 13C.

The upper frame part 3a is fixed to the outer peripheral part 16 of the window of the building by means of mounting screws 15, and the upper frame part 3a has a pivot point with the upper door plate 1a, that is, near the hinge 5. A fixed draining plate 17 is formed to cover 5.

Furthermore, a rotating draining plate 18 is formed at a position close to the hinge 5 on the upper door plate 1a side, and this rotating draining plate 18 has a flat plate portion 18a held approximately at right angles to the upper door plate 1a, and It is composed of a flat plate part 18a and a curved plate part 18b formed between the upper door plate 1a.

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 18g 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, on the indoor side surface, and in this four drain gutter 20, a plate body protruding from the inner surface 19 is formed at the upper part of the lower door plate 1b. The lower door plate 1b is bent in an L-shape in the direction.
In this embodiment, the drain gutter 20 is provided at both the upper and lower positions of the lower door plate 1b.

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, and the edges on the other end side are formed with the upper door plate 1a and the lower door plate 1b. The side plate fitting grooves 24 and 25 are formed in the side plate fitting grooves 24 and 25, 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 depending on 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 28, 29, 30
A glass door 31, 32 and a screen door 33 are respectively fitted in the.

The operation of the eaves 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 transmitted to the pulley 9as9b via the pulley mounting block 6. and the pulley 9a
, 9b are lowered while being pressed against the rear side of the guide rail 12, that is, toward the indoor side, but the force is dispersed between the upper and lower two pulleys 9a and 9b, allowing 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 1b 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 separately from the door plate 1 in a rectangular shape. or the unnecessary portion 26a depending on the size of the window etc. to be attached.

Since the side plates 21 and 22 are configured to be used by cutting out the portion 26a, the side plates 21 and 22 can easily fit windows of various sizes.

The eaves shutter according to the present invention can also have 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, the eaves shutter of this invention has a structure in which a drainage gutter is formed on the inner surface of the door plate, so that when the door plate is folded, rainwater that has entered between the door plates can be blocked by the closing operation. This has the effect of stopping the drain in the gutter when it is done.

Therefore, there is an effect that there is no risk of rainwater running down into the room.
