Description

[Detailed Description of the Invention] The present invention relates to a bay window shutter, and more particularly to an opening/closing device for a bay window shutter consisting of a three-panel folding door.

Conventionally, there is a device disclosed in Japanese Patent Application Laid-open No. 56-20290 as this type of opening/closing device for bay window shutters.
This opening/closing device connects adjacent ends of a middle shutter and an end shutter located on the front window side of a bay window shutter consisting of a three-panel folding door through a guided member guided by a guide groove. gears are integrally provided at the adjacent ends of the gears, and the gears are engaged with each other, and the guided member is pushed and pulled using a push-pull wire or the like to move the front window. The shutter is opened and closed while the end shutter on the lower side follows the opening and closing operation of the intermediate shutter. However, with this kind of opening/closing device, the structure is complicated and the cost is high, and the hinged parts of the intermediate shutter and the end shutter mesh with each other through gears, which makes it difficult for the shutter to open under strong winds, for example. There was a risk that the wind pressure load applied to the end shutter during opening and closing operations would apply an excessive force to the gear portion of the end shutter due to the so-called lever principle, causing damage to the gear.

In view of the above-mentioned problems, it is an object of the present invention to provide an opening/closing device for a bay window shutter that has an extremely simple structure, is easy to operate, and is less likely to malfunction.

An example of this will be explained below based on the drawings.
1 and 2, 1 is a bay window installed in a bay window opening 3 of a building wall 2, and includes an upper frame 4, a lower frame 5, and mullions 6 and 7 connected between the two frames. As a result, a front window section 8 and a pair of wing window sections 9, 9 sandwiching the front window section 8 are defined on the outer peripheral surface of the bay window. A fixed shoji 11 is fitted into each portion 9. Hollow upper and lower bay window overhang frame portions 12 and 12 are provided on the outer peripheries of the upper and lower horizontal frames 4 and 5, respectively, protruding outward from the window portions 8 and 9, and these bay window overhang frame portions 12 and 12 Rail grooves 13, 13 for both doors are opened and formed along the outer periphery of the bay window in the upper and lower opposing side walls. Also, among the bay window shutters 16, 17, 18, which are three folding doors that are pivotally connected by hinges 14, 15 so as to be foldable and extendable, the upper and lower portions on the free end side of the shutter 16 at one end are connected to the respective bay window overhang frames. It is pivotally attached to the base end of the wing window in the section 12 by a pivot 19 (FIG. 3), and the shutter 17 in the middle part has slide pins 20 ( (Fig. 4) is provided protrudingly, and this slide pin 20 is loosely fitted into the upper and lower shutter rail grooves 13 to support the intermediate shutter 17 in a slidable manner, and the shutter 18 at the other end is attached to the hinge 15. Only then is it connected to the intermediate shutter 17 in a suspended state. One end of an opening/closing operation rod 21 is pivotally attached to the shutter 18 at the other end at required portions of each of its upper and lower end surfaces with a pin 22, and the other end 21a of the opening/closing operation rod 21 is attached via a bolt 23. It is slidably engaged with each of the upper and lower shutter rail grooves 13, respectively. As shown in FIG. 5, the bolt 23 attached to the other end of the lower opening/closing operating rod 21 of both the upper and lower opening/closing operating rods 21 engages its head 24 with the hollow interior 12a of the bay window ledge 12. In the fitted state, it is slidably engaged with the shutter rail groove 13, and a lock nut 26 is screwed onto the threaded portion 25 of this bolt 23, and by tightening this lock nut 26, the opening/closing operation rod 21 is attached to the bay window ledge. The opening/closing operation rod 2 is crimped onto the side wall 27 of the section 12.
1 can be locked at any position in the rail groove 13 for the shutter. It is preferable that the head 24 of the bolt 23 be formed to have a width corresponding to the width of the hollow interior 12a so that it can slide along the hollow interior 12a but not rotate. The above-mentioned members 23-26 also constitute locking means 28.
In addition, the opening/closing operation rod 21 may be provided on both the upper and lower sides of the shutter 18, and when provided on both sides, a locking means for the upper opening/closing operation rod is not required.

Therefore, the bay window shutters 16, 17, and 18 can be opened by folding them into three at the wing window portion 9 and moving them toward the building wall 2, as shown on the left side of FIG. Sliding door shoji 10 for window section 8,
10 is opened and the other end 21a of the opening/closing operation rod 21 is grasped from the indoor side and pulled along the rail groove 13 toward the center of the front window section 8, and the bay window shutters 16, 17, and 18 are extended. Among these, the middle shutter 17 and the other end shutter 18 are connected to the rail groove 1.
By moving the slide pin 20, the shutter 1 is pulled out to the front window section 8 through the states shown in FIG.
6 rotates around the pivot portion 19 to close the armhole portion 9. Furthermore, in the open position of the shutter as shown on the left side of FIG. 2, the closed position of the shutter as shown on the right side, or the half-open position as shown in FIG. When the bay window shutters 16, 17, and 18 are locked, the bay window shutters 16, 17, and 18 are stably held in their respective positions.

As explained above, the bay window shutter opening/closing device of the present invention has one end of the opening/closing operation rod pivotally connected to the shutter at the other end which is suspended over the intermediate shutter, and the other end of the opening/closing operation rod. is slidably engaged with the storm door rail groove via a bolt, and the opening/closing operation rod is pushed and pulled along the storm door rail groove to open and close the storm door.
When opening and closing the shutters in strong winds, even if the end shutter on the front window side receives strong wind pressure, this end shutter will push and pull the opening/closing operation rod connected to it, and the shutter itself will open and close in the middle. Since it can freely rotate around the pivot joint with the end shutter, there is no risk of damaging it due to excessive wind pressure exerting excessive force on the gear part of the pivot joint of the end shutter, unlike in conventional devices. It can be used safely for a long period of time without failure.
Further, a bolt attached to the other end of the opening/closing operation rod is slidably engaged with the rain door rail groove with its head fitted into the hollow interior of the bay window flange, and the bolt is slidably engaged with the rain door rail groove. A lock nut is screwed into the threaded part of the shutter, and by tightening the lock nut, the opening/closing operation rod is clamped between the bay window ledge frame part, so that the shutter can be reliably locked in any position. can. Furthermore, this locking means does not consist of a special locking mechanism, but rather uses a bolt attached to the end of an opening/closing operation rod that is part of the shutter opening/closing device, and a lock nut is screwed into the threaded part of this bolt. Since it is made of metal, its structure is simple, and the locking operation is also extremely simple since all you have to do is tighten the locking nut.

Furthermore, the bay window shutter opening/closing device of the present invention has an opening/closing operation rod attached to the other end of a triple-folding shutter as described above, and therefore has an extremely simple structure and is easy to manufacture. Therefore, it can be provided at a low cost, and it can be operated very easily since it is only necessary to move the opening/closing operation rod along the rail groove for the shutter.
