Description

[Detailed explanation of the idea] This idea relates to shutters attached to bay windows.

Three sides of a bay window are made of glass; for example, it is extremely difficult to install a shutter in the case of a bay window that is entirely made of glass, such as a bay window with double-walled glass windows on both sides and a sliding glass shoji screen on the front.

The purpose of this invention is to provide a storm door suitable for a bay window that is entirely filled with glass.The purpose of this invention is to provide a shutter that is suitable for a bay window that is entirely filled with glass. It is formed by engaging with.

Embodiments of this invention will be described below with reference to the drawings. FIG. 1 is a perspective view seen from the outside. The bay window, which is generally designated by the reference numeral 1, is attached to the frame of the building and protrudes outward from the wall 2, like a normal bay window.

FIG. 2 is a vertical cross-section of the bay window 1 in the forward direction, and FIG. 3 is a horizontal cross-section. The bay window 1 is assembled at the four corners of the opening 3 of the building at the ends of the arms 5 fixed to the pillars 4 of the building frame, and the frame is constituted by the upper frame 6, the lower frame 7, and the vertical frames 8, 8. , 8, the pillars 4 of the building frame parallel to them, and the upper and lower arms 5 that span them.
A glass 9 is fitted in between, and an outer shoji 11 and an inner shoji 12 are fitted in a double-sliding manner within the frame surrounded by the front upper frame 6, lower frame 7, and vertical frames 8, 8. A roof 13 and a base plate 14 are provided. The above explanation is the same as that of a normal bay window that is entirely made of glass.

A guide rail 15 is fixed to the pillar 4 or to the bay window 1 in the vertical direction in parallel to the pillar 4, and a guide rail 16 is fixed to the vertical frame 8 along the vertical frame 8. A bellows 17 which is vertically expandable and retractable is disposed so as to cover the outside of the bay window 1 and has a U-shape in plan view. The bellows 17 has its lower end fixed to the lower arm 5, the lower frame 7, etc. at the position of the lower frame 7. Bellows 17 is the second
As shown in FIG. 4, which is a partially enlarged view of the figure, the inner ribs 18 of the wire bent into a U-shape in plan view and the outer ribs 19 which are C-shaped in plan view but are not connected at the corners are arranged alternately. It is integrally molded with a synthetic resin film 21. As shown in Fig. 5, which is a partially enlarged view of Fig. 3, the guide rails 15, 16
At the position, a slide adapter 22 is fixed to each inner bone 18 and protrudes from the synthetic resin film 21,
The tips of 23 are engaged with guide rails 15 and 16 so as to be able to move up and down, respectively. A handrail 24 is fixed to the inner bone 18 at the top in a U-shaped plan view. Handrail 2
4 is vertically movably engaged with a guide rail 25 having a T-shaped cross section fixed along the vertical frame 8 and a guide rail 26 having a T-shaped cross section fixed perpendicularly to the building frame.

The portion of the handrail 24 that engages with the guide rails 25 and 26 is provided with a T-slot 27 in the vertical direction as shown in FIG. 7, which is a perspective view of the handrail 24.
The legs 28 are attached to the handrails 24 so that they can move up and down smoothly.
The T-slot 27 is made sufficiently long.
The length of the leg member 28 is such that the handrail 24 is at a height above the base plate 14 as a handrail.

The bellows 17 functions not only as a shutter but also as a handrail when opened as shown in FIG. 1 since there is a handrail 24 thereon. When the handrail 24 is lifted up in FIG.
26 and ascend. At that time, the inner bone 18 is connected to the guide rail 15 by the slide adapters 22 and 23.
16, the bellows 17 extends vertically along the bay window 1, and when the handrail 24 reaches the upper frame 6 and upper arm 5, it is locked by a locking tool (not shown). For example, a magnet may be fixed to each of the upper frame 6, upper armrest 5, and handrail 24 so that they are attracted to each other, or a magnet and a magnetic material may be fixed to each of them.

To open the bellows 17 from the closed state, pull down the handrail 24 and the T-slot 27 will open the guide rail 2.
5 and 26, the inner bone 18 is guided by the slide adapters 22 and 23 by the guide rails 15 and 16, and the inner bone 18 is successively lowered. Thus, the leg material 28 is the lower frame 7,
It comes into contact with arm bar 5, etc. In this state, the handrail is in use.

Incidentally, when the bellows 17 is contracted, the outer rib 19 moves outward and the synthetic resin film 21 is folded.

To reduce the height of the handrail 24, the leg members 28 are shortened. In this case, rollers or slide bearings are suitable for guiding the handrail 24 and the inner frame 18 to the guide rail. In this case, the guide rails 16 and 15 are extended downward so that the glass portion of the bay window 1 is completely exposed, and the lower end of the bellows 17 is fixed at the lower end of the guide rails 16 and 15. When doing this, when the bellows 17 is retracted, the handrail 24 is attached to the lower armrest 5 and the lower frame 7.
The glass surface of the bay window 1 is exposed to the entire surface. In this case, in order to lock the handrail 24 in the middle, it is preferable to provide a latch shown in a horizontal sectional view in FIG. 6. In FIG. 6, a round rod-shaped latch piece 31 having a knob 29 is fitted into a bracket 32 fixed to the vertical frame 8 so as to be movable in the direction of projection.
The part where the knob 29 protrudes outward is the bracket 3.
2 is cut out. The latch piece 3 is pressed by the knob 29.
1 to protrude below the handrail 24, or by making a hole in the inner surface of the handrail 24 into which the latch piece 31 is inserted, the handrail 24 can be fixed at any intermediate position and functions as a handrail.

Although the above-mentioned storm door is a bay window having a rectangular plan view, the storm door of this invention can be similarly provided for a triangular bay window having a triangular plan view, a bay window having a trapezoidal plan view, or other irregularly shaped bay windows.

As mentioned above, the rain door of this idea is equipped with a vertical guide rail on the bay window and a bellows that can be expanded and contracted in the vertical direction to cover the bay window, so even if the bay window is made entirely of glass, the rain door can be attached. can also be used as a handrail.
