Description

[Detailed explanation of the idea] This idea relates to a bay window equipped with a shutter.

Traditionally, when terraces and windows with sliding shoji had shutters on one side, a door pocket was required, but the door pocket was only considered to function as a door pocket.
Attaching an independent door pocket to the exterior side of one side of the window means that the door extends outward, and especially when it is attached to a bay window, it will look extremely prominent. Furthermore, when a door pocket is provided on the inside of a bay window, it is not possible to effectively utilize the inside of the door pocket. Furthermore, if a bay window is structured so that it is guided by a single guide rail like a normal storm door, it is difficult to move the shutter in the forward direction when pulling out the shutter from inside the door pocket.

The purpose of this invention is to provide a structure for a storm door that makes effective use of the inside of the door pocket, and is particularly aimed at obtaining a structure for a storm door suitable for use in bay windows.

This idea provides one or more shutter guides on the upper surface of the upper frame and the lower surface of the lower frame of the opening, and in those with multiple guides, the external shutter is used for the internal guide, and the external shutter is used for the external guide. Engage the inner shutters in sequence,
The inner and outer shutters are designed to be able to slide back and forth, and in the case of a bay window, a storage space, a display shelf, a bookshelf, etc. are formed inside the door pocket.

Embodiments of this invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the bay window viewed from the inside, and FIG. 2 is a front view of the bay window viewed from the outside. The opening frame 1 is fixed to the building frame, and although details are not shown, a bay window frame 2 is provided at the end of the arm extending outward from at least the four corners of the opening frame 1.
The bay window frame 2 has an upper frame 3, a lower frame 4, and vertical frames 5 and 6 assembled in a four-sided manner, and the upper frame 3 and the lower frame 4 are connected by a mullion 20. The space between the opening frame 1 and the bay window frame 2 is separated from the inside and outside by wall members such as a roof plate, a base plate, and a side wall.

Airtight gaskets 64, 65, 66 that come into contact with the outer storm door 40 when the outer storm door 40 is closed are locked to the outside of each of the upper frame 3, the lower frame 4, and the vertical frame 6, and the inner storm door 41 is closed. Airtight gaskets 67, 68, and 69, which come into contact with the inner storm door 41 at times, are secured to the upper frame 3, the lower frame 4, and the mullion 20. Although the gas-tight gaskets 67 and 68 do not appear in FIG. 3, they are aligned in a row in the respective grooves of the upper frame 3 and the lower frame 4 into which the gas-tight gaskets 64 and 65 are fitted, in contact with the gas-tight gaskets 64 and 65. .

This section describes how to open the shutters from the situation shown in Figure 4. When the inner shoji 28 is opened and the inner shutter 41 is moved to the left, the door roller 45 of the inner shutter 41 rolls on the upper frame 3,
Since the upper part of the inner storm door 41 is urged toward the outside by the moment due to the gravity of the inner storm door 41, the roller 43' moves toward the outside along the cam plate 60, and the rollers 55' and 55 move toward the outside of the guide rail 52. Move to a more straight line section. The outer shutter 40 and the inner shutter 41 are engaged at the smoke return 57 and 58, so the outer shutter 40
At the same time, the rollers 42 and 4 of the outer shutter 40 move to the left.
2' moves to the outside according to the cam plates 59, 59', and the rollers 54, 54' move from the notch of the guide rail 53 to the straight portion. Thus the outer shutter 4
0, the pull of the inner shutter 41 is released.

When the inner shutter 41 is moved to the left and moved to the door pocket position, the outer shutter 40 comes to the position where the inner shutter 41 was, and when the outer shutter 40 is further moved to the left, only the outer shutter 40 moves and overlaps with the inner shutter 41. . During movement, rollers 42 and 43 are set higher than cam plates 59' and 60, respectively, so that they do not interfere with each other, and rollers 54 and 55 are set lower than cam plates 61' and 62, so that they can be moved without interference.

When closing the outer shutter 40 and the inner shutter 41 from the open state, the inner shutter 28 is opened and the outer shutter 40 is moved to the right in FIG. 4 until the entire width of the outer shutter 40 or more is exposed. The outer shutter 40 has a smoke return 57,
58, pull out the inner shutter 41. Next, both the outer shoji 19 and the inner shoji 28 are moved to the left, and then the outer shutter 40 is moved to the left. Just before the inner shutter 41 is pulled and closed, the rollers 42, 42', and 43' are moved to the cam plate 5, respectively.
9, 59', 60, and smoke return 57,
58 is engaged, the outer shutter 40 and the inner shutter 4
The upper part of 1 is pulled together. At the same time rollers 54,5
Since the cam plates 4' and 55' are engaged with the cam plates 61, 61', and 62, and the smoke returns 57 and 58 are engaged, the lower portions of the outer shutter 40 and the inner shutter 41 are pulled together.
The roller 55 then enters the notch 63. As the outer storm door 40 and the inner storm door 41 are pulled together, the airtight gaskets 64, 65, and 66 come into contact with the inner side of the outer storm door 40, and the airtight gaskets 67, 68, and 69 abut against the inner side of the inner rain door 41, respectively, to ensure airtightness. It is maintained.

When opening and closing the outer shutter 40 and the inner shutter 41, the relative positions of the rollers and the cam plate are already set as shown above, so when the outer shutter 40 is moved, the roller 42 passes through the cam plate 59' without interfering with it. However, the roller 54 passes without interfering with the cam plate 61', and when the inner shutter 41 is moved, the roller 43 passes without interfering with the cam plate 60, and the roller 55 passes without interfering with the cam plate 62.

As described above, the storm door of this invention does not require a door pocket, and the inside of the door pocket can be used effectively, so it is suitable for application to a bay window. Since the upper and lower frames of the opening are covered, it is convenient for preventing wind and rain from blowing in. Since the number of shutter boards can be stacked, the number of shutter boards can be further increased.

FIG. 9 shows another embodiment of this invention. The upper frame 3' and the lower frame 4' have guide grooves 71 and 7 on the outside, respectively.
The inner storm door 41' is supported by sliding guide pieces 73 and 74 provided on the upper and lower flanges of the inner storm door 41'. A guide piece 77 is fixed to the upper flange of the outer shutter 40' so as to hold a protrusion 76 having a groove into which an airtight gasket 75 is fitted to seal the space between the upper frame 3' and the outer shutter 40'. 77 is in contact with the protrusion 76 to support the moment of outward tilting of the outer shutter 40', and is an airtight gasket 78 that seals between the lower frame 4' and the outer shutter 40'.
A guide piece 81 is fixed to the lower flange of the outer shutter 40' so as to hold a protrusion 79 with a groove into which the outer shutter 40' is inserted, and the force directed inward due to the moment of outward falling of the outer shutter 40' is The guide piece 81 is adapted to abut and receive the protrusion 82.

As described above, the shutter of this invention has a flange that spans the entire width of the shutter and is bent upward and downward toward the inside, so that the upper and lower frames are covered from the outer circumferential side.
It works well as a rain door. Since the shutter can be guided by the upper and lower surfaces of the upper frame, no door pocket is required. Since the space inside the door pocket can be used effectively, it is particularly suitable for bay windows. If you have multiple shutters,
Each shutter is guided by a separate guide, making it easy to operate. If there are multiple shutters, a smoke return can be installed on the stile to increase the airtightness of the shutters. Since the rail member that guides a normal storm door does not protrude to the outside of the upper frame, the window feels brighter and larger.

In addition, although it is mentioned about the shutter, it can be configured as a sliding shoji installed in the opening frame, and the upper and lower stile of the sliding shoji are placed outside the upper and lower frames of the opening frame or diagonally above and below them. The glass can be made larger and the lighting area can be expanded. When used for terrace doors, there is no rail to guide the shoji on the inner circumference of the lower frame of the opening frame, making it easy to sweep out. Furthermore, when the shoji is opened, there are few irregularities on the inner periphery of the opening frame when viewed from inside and outside the room, giving a sense of smoothness.
