Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a bay window shutter, and particularly to its opening/closing structure.

(Prior art) As described in Japanese Utility Model Application Publication No. 58-73883, conventional bay window shutters connect the ends of three adjacent windows rotatably to each other, and connect the intermediate shutters to each other. The spindle provided at the tip of the slider is configured to loosely fit into the groove of the shutter rail.

(Problem to be Solved by the Invention) However, according to this conventional configuration, the most advanced shutter, that is, the shutter on the opposite side of the one that is pivoted to the base end of the window frame, cannot be used when the shutter is opened or closed. The front and back sides are reversed, and when opened, the handle and locking device on the indoor side are visible, making it look bad.In addition, since the indoor side faces toward the outdoor side, dust can adhere to the indoor side. There are problems such as dirt and buildup.
In addition, the most advanced shutters flip over as the shutters are opened and closed, resulting in poor operability.

In addition, according to the above conventional structure, the tip of the most advanced shutter, that is, the gassho frame part, is not restrained, so a locking mechanism must be provided on the gassho frame to prevent rattling, and that part has a bay window. There is a problem in that it is difficult to lock and unlock the shutters because of the shoji fittings on the main body.

In addition, when the shutters are fully opened, the three shutters overlap, so the light is blocked from the lighting area on the side of the bay window by the thickness of the shutters, and if the lighting area is a transparent glass window, the visibility is narrowed. There is a problem with storing it away.

(Means for Solving the Problems) In view of the problems of the prior art described above, the present invention provides a bay window shutter that includes a first shutter pivotally attached to the proximal end of the bay window frame, It consists of a second shutter pivotally attached to the tip of the shutter, and a third shutter pivotally attached to the tip of the second shutter, and the total width of the first storm shutter and the second shutter is the third shutter. The width of the third shutter is approximately equal to the width of the third shutter, and a guide device (roller, shaft, hanging wheel, door wheel, etc.) that moves along the guide portion (guide rail or guide groove, etc.) of the window frame is provided at the tip of the third shutter; In the fully open state of the shutter, the third shutter faces the first and second shutters and overlaps them in a folded manner. With this structure, state-of-the-art shutters do not flip when opened or closed;
In addition, when the shutter is fully open, it is as if two shutters are stacked on top of each other, and the gassho frame portion of the third shutter at the forefront is restrained by the engagement between the guide tool and the guide groove. Therefore, the locking mechanism can be provided not in the gassho frame part of the third shutter but in a part near the corner part of the window frame.

(Example) An example of the present invention will be described below with reference to the drawings.
FIG. 1 is a cross-sectional view showing about half of the bay window, and FIG. 2 is a vertical cross-sectional view showing the leading edge of the shutter in the guide groove of the window. In the figure, 1
is the lower frame of the bay window frame, 2 is the upper frame, 3 is the vertical frame,
These are configured so that the planar shape forms a trapezoid,
A lower frame 4 and an upper frame 5 for shutters are coupled to the lower frame 1 and the upper frame 2. The lower frame 4 and the upper frame 5 for the storm door may be formed of integral molding materials on the upper frame 1 and the lower frame 2, respectively. A sliding shoji 6 is attached to the front end of the window frame of this bay window, and fitted windows 7 are attached to the side surfaces on both sides. 8 is the outer wall of the building.

9, 10, and 11 are first, second, and third shutters according to the present invention, and the first shutter 9 has a vertical stile 12 at one end attached to the vertical frame 3 at the base end of the window frame via a hinge 13 A hinge 15 is attached to the vertical stile 14 on the tip side of the first shutter 9.
The tip side vertical stile 16 of the second storm door 10 is pivotally connected to the tip side vertical stile 17 of the second storm door via a hinge 18, and the proximal side vertical stile 19 of the third storm door 11 is pivotally connected to the tip side vertical stile 17 of the second storm door. It will be done. These shutters 9 to 11 are attached to the left and right, respectively, and the third shutters 11 are butted against each other at the joining part 31 of the shoji 6.

Tip-side vertical stile (gassho stile) 2 of the third shutter 11
0, a shaft 21 is attached to its lower end, and the shaft 21
A guide roller 22 is attached to the guide roller 2.
2 is loosely fitted into a guide groove 23 provided in the lower frame 4, and a shaft 24 is attached to the upper part of the vertical stile 20 so as to be swingable.
A hanging wheel 25 is attached to the shaft 24, and the hanging wheel 25 is placed on a guide rail 26 provided on the upper frame 5 so as to be freely rollable.

Further, the total width of the first shutter 9 and the second shutter 10 is configured to be approximately equal to the width of the third shutter 11. Further, the width of the first shutter 9 is approximately equal to the length of the side surface of the bay window, and the total width of the second shutter 10 and the third shutter 11 is approximately half the width of the front surface of the bay window.

Further, in this embodiment, the first shutter 9 and the second shutter 10 are connected by a hinge 16 so that they can be bent to the angle of the corner portion 27 of the bay window (for example, 60 degrees), and First shutter 9
By protruding the rotation angle regulating plate 28 fixed to the vertical stile 14 of the second shutter 10 to the outdoor side of the second storm door 10,
The second storm door 10 is configured not to rotate beyond a straight line with respect to the first storm door 9. Furthermore, the second shutter 10 and the third shutter 11 have a range of 180 degrees, ranging from a linear shape to a folded shape overlapping range.
They are connected by a hinge 18 so that they can rotate within a range of degrees.

In this shutter, in the closed state C, the hinge 16 that connects the first shutter 9 and the second shutter 10 faces a corner portion 27, is bent at this portion, and the second shutter 9 is bent at this portion. The shutter 10 and the third shutter 11 form a straight line and cover the front part of the bay window. From this closed state C, the third shutter 11 can be opened and closed by gripping the handle, operating rod, etc. (not shown), or by using a remote opening/closing mechanism (not shown) using rollers, strings (or sprockets, chains), etc. Alternatively, if these are moved in the opening direction using an automated opening/closing mechanism, etc., the vertical stile 20 of the third shutter 11 can be opened.
The hanging wheel 25 attached to the shutter rolls along the guide rail 26, the guide roller 22 moves along the guide groove 23, and the connection part (hinge 18) with the second shutter 10 draws a trajectory shown by 30. After passing through the intermediate state shown in B, the fully open state is reached as shown in A.
In this fully open state, the first shutter 9 and the second shutter 10 form a straight line, and the third shutter 11 is folded so as to face these shutters,
It will be as if two shutters have been folded. Moreover, since the third storm door 11 is not reversed during the opening/closing operation, the outdoor side surface remains facing the outdoor side. The leading edge of the third shutter 11, that is, the gassho frame 20 portion, is engaged with the guide roller 22 and the guide groove 23, and the suspension wheel 25 and the guide rail 26.
Even if a locking mechanism is provided in a part of the shutter close to the window frame corner 27 (for example, the part shown at 32 in FIG. 1), the tip of the shutter 11 can be fixed without wobbling. Because it is possible to
Locking and unlocking can be performed by simply opening the shoji 6 a little.

In addition, in this embodiment, since the rotation angle regulating plate material 28 is provided, when opening the shutter, the first shutter 9
Since the second shutter 10 does not rotate beyond the angle that forms a straight line, when opening the shutter 11, the hinge 16
The connecting part and stiles 14 and 15 are the third shutter 1.
1, and damage caused by the collision is prevented.

In addition, in the above embodiment, the case where the planar shape of the bay window is trapezoidal has been explained, but there are also cases where the planar shape is rectangular, and the part corresponding to the corner part 27 of the trapezoidal or rectangular bay window is the front surface of the bay window and the side surface. The present invention can also be applied to a surface formed to be inclined at a certain angle with respect to the surface.
Further, when carrying out the present invention, the third storm door 11 may be configured to have a door wheel swingably attached to its lower part, and a guide shaft or a guide roller provided at its upper part. Furthermore, the shutters 9 to 11 may be connected using rods.

Moreover, various changes and additions can be made to the specific shapes of the shutters 9 to 10, window frames, etc., and their combination structure, etc., without departing from the gist of the present invention.

(Effects of the Invention) As described above, in the present invention, the total width of the first shutter pivoted to the base end of the window frame and the second shutter pivoted thereto is equal to the width of the second shutter. The width of the third shutter is approximately equal to the width of the third shutter which is pivotally connected to the third shutter, and a guide member is provided at the tip of the third shutter that moves along the guide portion of the window frame, so that when the shutter is fully opened, the width of the third shutter is approximately equal to that of the third shutter. Since the third shutter faces the shutter and overlaps it in a folded manner, the third shutter, that is, the most advanced shutter, does not turn inside out when the shutter is opened and closed. Therefore, when the shutter is fully opened, dust and the like will not adhere to or accumulate on the indoor side surface of the shutter, allowing it to be kept clean. Furthermore, when the storm door is opened, the handle and locking device on the indoor side are not visible, giving it a good appearance and an excellent design. Furthermore, since the most advanced shutter does not turn over when the shutter is opened or closed, the movement associated with opening and closing becomes easy and the operability is good.

In addition, in the structure of the present invention, the tip of the most advanced shutter, that is, the gassho frame part, is restrained, so a locking mechanism can be provided in the part of the shutter close to the window frame corner, so you can simply open the shoji a little. It can be locked and unlocked.

Furthermore, in the present invention, when the shutters are fully opened, they are folded close to the building as if two shutters were overlapped, so if a window with transparent plate glass or the like on the side of the bay window is used. The visibility will be good, and if a transparent plate is used, the lighting will be good.
