Description

[Detailed description of the invention] [Purpose of the invention] "Industrial application field" This invention relates to a storm door installed on a bay window.

"Conventional technology and its problems" Conventionally, installing a shutter on a bay window requires a door pocket, so a shutter is often not attached. If a shutter is attached, the shutter will be attached horizontally like a normal window, and a door pocket will be provided next to the opening, so the opening will be restricted in the facing direction as a bay window.

Also, if the entire three vertical sides of a bay window are made of glass, it is difficult to attach shutters. It is especially difficult to attach shutters when the three sides of a bay window are fitted together.

A particular object of the present invention is to provide a shutter suitable for a bay window whose three sides are made of glass.

This invention relates to a bay window shutter in which each surface of the vertically intermediate part of the bay window is an opening, and both upper and lower sides are provided with external wall panels, and the shutter is divided into upper and lower parts along the vertical plane of the bay window so as to cover the opening of the bay window. , comprising an upper storm door and a lower shutter that fit vertically movably into a vertical guide rail provided on the frame material of the bay window on the outside of the bay window, and are connected to ends of ropes wound around a pulley provided at the top of the bay window, respectively. This is a bay window shutter characterized in that the lower shutter is placed on the inside of the upper shutter, and the upper and lower shutters are arranged in a sliding position.

"Embodiments" Examples of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a bay window with a shutter according to the present invention viewed from the outside. Figure 1 shows the bay window with the upper shutter 1 and lower shutter 2 open. Second
The figure shows the state in which the upper shutter 1 and lower shutter 2 of Figure 1 have been removed. FIG. 3 shows the upper shutter 1, the lower shutter 2, and the parts that operate them in relation to each other.

The framework of the bay window is similar to that of a normal bay window, with at least four arms 3 extending outward from the building frame, and beyond which the bay window end horizontal members 4, 5 and vertical frames 6, 6 are assembled on all sides. , a roof 7, and a base plate 8 are provided.

The outer periphery of the bay window of this invention is formed by connecting the vertical frames 6, 6 at about a quarter of the length from both ends of the vertical frames 6, 6, and passing the upper frame 11 and the lower frame 12, and further on the side wall side. A side wall upper frame 15 and a side wall lower frame 16 are provided in accordance with the upper frame 11 and the lower frame 12 between the vertical frame 6 and the column 13 as a member parallel to the frame column or the frame column.

Surrounded by vertical frames 6, 6, upper frame 11, and lower frame 12, outer shoji 17 and inner shoji 18 of sliding shoji containing glass guided by upper frame 11 and lower frame 12 are fitted. Side wall vertical frame 6, pillar 13, upper frame 15, lower frame 16
A piece of glass 14 is inserted in between. The upper and lower parts of the sliding shoji and glass 14 are all made of external wall boards 20.
It is becoming.

FIG. 4 is a horizontal sectional view of the bay window. Guide rails 19 and 21 are provided vertically on the outside of the bay window. The guide rail 19 is provided integrally with the vertical frame 6 or fixed to the vertical frame 6, and the guide rail 21 is provided on the column 1.
The guide rails 19 and 21 of the upper shutter 1 and the lower shutter 2 slide into these guide rails 19 and 21, respectively. Or guide rails 19, 21 (not shown)
Place the guide rollers on the upper shutter 1 and the lower shutter 2 so as to hold the
may be provided.

FIG. 5 is a sectional view taken along the line AA in FIG. 4, and FIG. 6 is a sectional view taken along the line BB in FIG. A rotatable pulley mechanism 25 is fixed to the vertical frame 6 at the side member position on the circumferential edge of the roof 7, and the rope 2 around which the pulley mechanism 25 is wound is fixed.
6 is fixed to the upper shutter 1 at one end and the lower shutter 2 at the other end. As shown in FIG. 5, the upper shutter 1 is located so as to overlap the outer side of the lower shutter 2. Therefore, the upper shutter 1 and the lower shutter 2 can be assembled in the closed position to prevent rain. The upper frame 1 is attached to the inner corner of the upper end of the upper shutter 1 when the upper shutter 1 is closed.
1. Inclined outer member 11' provided on the side wall upper frame 15;
An airtight gasket 24 made of an elastic material is attached to press against the vertical frame 15' and close to the outer surface of the vertical frame 6 to close the gap between the upper shutter 1 and the periphery of the bay window. The rope 26 is loosely inserted through the hole in the airtight packing 24, and at the part where it is attached to the lower shutter 2, it comes into a gutter 30 fixed to the lower shutter 2 for draining water to the outside. Therefore, when the rainwater on the rope 26 comes down along the rope 26, it is guided into the gutter 30 and discharged to the outside. Alternatively, the rain closing and airtightness of the upper storm door 1 can be achieved with the airtight packing 24 or by eliminating the airtight packing 24 and using the fifth
As shown in FIG. 6, the door pocket 43 is fixed under the eaves of the roof 7, and is wound so that the upper storm door 1 is stored between it and the outer wall board 20 on the almost upper side. The protrusions 45 of the upper shutter 1 may be overlapped.

The arrangement of the guide rails 19, 21 and the pulley mechanism 25 is such that the guide rails 19, 21 mutually complement the guided objects, the upper shutter 1 and the lower shutter 2, so that the guide rails 19, 21 complement each other in the expected direction. In the case where the rotation moment is supported, the pulley mechanism 25 is set so that the center of gravity of the upper shutter 1 and lower shutter 2 passes through the center of gravity of the upper shutter 1 and the lower shutter 2 so that they do not rotate around the horizontal axis. It is desirable to locate them on both the left and right sides of the direction line. When installing the pulley device 25 near the pillar 13, the shape of the guide rail 21 (narrow guide) is formed so that the guide rail 21 can receive forces in all directions, and the guide rail 19 is either not attached or used as an auxiliary. establish. When the guide rail 21 is used as the main guide, it is preferable that the guide rail 21 be held by rollers rather than guide grooves in the upper and lower shutters 1 and 2.

The inside of the outer wall board 20 is partitioned by shelf boards 27' and 28', and storage parts 27 and 28 are provided. Either lower the upper shutter 1 (not shown) by pulling it down, or lower the lower shutter 2.
When the upper shutter 1 and the lower shutter 2 are pulled up by the hand, the upper shutter 1 and the lower shutter 2 are linked by the rope 26 hooked to the pulley mechanism 25 and move in opposite directions.
approaches and closes. On the contrary, pull up the upper shutter 1 or
It opens by pulling down the lower shutter 2.

FIG. 7 is a perspective view of an embodiment of the operating mechanism provided on the shutter, and FIG. 8 is a horizontal sectional view thereof. Pulley device 25
A rotary shaft 29 fixed to the rotary shaft 29 is rotatably supported by passing through the outer wall board 20, and a pulley 31 is fixed to the rotary shaft 29 inside the bay window.An endless rope 32 is wound around the pulley 31, and the ropes 32 are attached to the outer wall respectively. The lower outer wall board 2 is wrapped around pulleys 33 and 34 pivotally mounted within the board 20.
It is wound around a pulley 35 fixed to a shaft 36 which is rotatably supported inside 0. A handle 37 is provided on the shaft 36. In this case, the storage portions 27 and 28 are provided excluding these portions.

When the handle 37 is rotated, the shaft 36 rotates and the pulley 35 rotates. The rope 32 moves and rotates the pulley 31 via the pulleys 33 and 34, which in turn rotates the rotating shaft 29, so the pulley mechanism 25 rotates.
Therefore, the upper shutter 1 and the lower shutter 2 can be operated from within the room. In the case of electric power, a reduction motor may be connected directly to the rotating shaft 29.

If such an operating mechanism for the upper shutter 1 and the lower shutter 2 is provided, the upper shutter 1 and the lower shutter 2 can be operated even if all three sides of the bay window are fitted with glass. In other words, shutters can be attached to bay windows fitted with three-sided glass.

FIG. 9 shows another embodiment of the guide rail of the upper storm door 1, and is a drawing of one of the two positions of the guide rail 21 seen from the viewing direction, with the right side being the inside side. In contrast to the above embodiment in which the guide rails of the upper shutter 1 and lower shutter 2 were made of the same material, the guide rails of the upper shutter 1 and the lower shutter 2 were
In order to improve airtightness and rain protection by drawing the pillars closer together, the two guide rails on the pillar 13 side are divided into upper and lower sections and guide rails 38 and 39 are provided, respectively, as shown in FIG. The lower ends of the guide rails 38 and 39 are bent in the direction of view corresponding to the position where the upper shutter 1 is closed.
A short eave 41 is exposed above the upper frame 15. Upper and lower shutters 1 are provided with rollers 42 and 42' whose shafts serve as support arms and which can be fitted into guide rails 38 and 39 fixed to upper and lower shutters 1 to roll. When the upper shutter 1 is lowered, the rollers 42 and 42' move towards the guide rail 3.
8, 39, the rollers 42, 42' change direction and move inward just before the descending upper shutter 1 closes, and the upper shutter 1 closes below the eaves 41. However, in this case, the bay window is limited to the case where the plan view is trapezoidal and the guide rail 19 allows the upper shutter 1 to move in the forward direction. In this way, the rain door itself can shut off the rain, and it also has airtight material to improve insulation performance.
It can also improve sound insulation performance. Further, the lower shutter 2 may be drawn in the same way.

In the above explanation, the end of the bay window has an opening in the center and outer wall boards above and below it, but it does not necessarily have to be distributed this way. Even in the case where a movable shoji is provided and the sides are fitted together, the guide rails 19 and 21 may be extended both upward and downward.

〔Effect of the invention〕

This invention relates to a bay window shutter in which each surface of the vertically intermediate part of the bay window is an opening, and both upper and lower sides are provided with external wall panels, and the shutter is divided into upper and lower parts along the vertical plane of the bay window so as to cover the opening of the bay window. , comprising an upper storm door and a lower shutter that fit vertically movably into a vertical guide rail provided on the frame material of the bay window on the outside of the bay window, and are connected to ends of ropes wound around a pulley provided at the top of the bay window, respectively. , because the lower shutter is located inside than the upper shutter, and the upper and lower shutters are arranged in a sliding position.(1) Because the upper and lower shutters are in a sliding position. , each end of the rope wrapped around the pulley comes to the upper end surface of the upper and lower shutters. Therefore, both the upper and lower shutters can be made into a simple plate shape that follows the surface of the outside of the bay window, and the ropes that hang the shutters do not apply any force that causes them to deviate laterally. In addition, the connecting part of the rope end to both shutters can be provided on the upper end surface of both shutters, so it can be connected without the need for other parts, the joint is simple, and there is no need to consider interference between the joint and other parts. There is no.

(2) Since the guide rail is oriented vertically,
Unlike normal horizontal shutter rails, there is no need for maintenance as there is no chance of foreign matter being accumulated outside and being exposed to the outside.

There are other effects.

The embodiment has advantages such as convenience because a storage section can be provided inside the outer wall board 20 in the portion corresponding to the door pocket.

According to the embodiment in which the operating part of the pulley operating mechanism is guided to the indoor side, a shutter can be installed even when three sides of the bay window are covered with glass.
