Description

[Detailed description of the invention] This invention relates to a ventilation shutter that is attached to a sash frame attached to a window opening in a building.

Conventionally, the multiple slats of this type of ventilation storm door include those with screw receivers and those without screw receivers, and those with screw receivers are attached to the frame material with screws through the screw receivers, and The siding without a support had to be temporarily fastened to the auxiliary crosspiece and then assembled to the frame assembly, which had the drawback of requiring extremely laborious work.

The present invention was devised in view of the above-mentioned conventional drawbacks, and its purpose is to provide a ventilation storm door that can easily connect multiple slats and assemble them into a frame assembly in a labor-saving manner. It is a ventilation storm door with multiple blades attached to the frame assembly with gaps between them.
Dovetail grooves are formed at the upper and lower ends of each slat, so that the dovetail grooves of adjacent slats face each other, and connecting pieces are interposed between the opposing dovetail grooves at both ends of the stile to form the dovetail grooves in the frame assembly. This ventilation storm door is configured to be inserted between the grooves of a stile of a body, and to fix a screw from the stile side to a screw receiving hole formed in the connecting piece.

In addition, a dovetail groove 12b facing outdoors is formed at the upper end of the blade 12a of the lower blade board 12C, and a cross section of approximately C that fits into the groove 11H of the lower stile 11 is formed at the lower end.
A shaped fitting portion 12e is formed, and a screw receiver 12f is formed along the longitudinal direction of the fitting portion 12e. Among the slats 12A, 12B, and 12C formed in this way, the intermediate slat 12A and the lower slat 12C, which are attached to the vertical portion 10A of the vertical stile 10, are formed to have the same length, and
Intermediate blade plate 12 attached to bent portion 10B portion
A and the upper blade plate 12B are formed to be shorter stepwise along the bent portion 10B, and each blade plate 12A, 1
A locking hole 12g that engages with a locking protrusion 13D of the connecting piece 13 is provided at both ends of the dovetail grooves 12b and 12c of 2B and 12C.

Reference numeral 13 denotes a connecting piece. This connecting piece 13 is made of synthetic resin or synthetic rubber, and connects the blade plates 12 to each other via their dovetail grooves 12b and 12c, and maintains a predetermined gap T between the blade plates 12. On both sides of the block-shaped regulating part 13A, which regulates the interval between the two fitting parts 13B, a fitting part 13B having a substantially horizontally convex cross section that fits into the dovetail grooves 12b and 12c is formed. A locking protrusion 13D that fits into a locking hole 12g extending through the blade plate 12 is provided in the center. Further, a screw receiving hole 13F is provided through the side surface 13E of the regulating portion 13A.

The connecting piece 13 formed in this way has dovetail grooves 12b, 12 of each blade plate 12A, 12B, 12C.
The same grooves 12b,
12c and the locking protrusion 13 in the locking hole 12g.
After engaging the slats 12A, 12B, and 12C to connect the slats 12A, 12B, and 12C, both ends of the stile 12 connected from the lower stile 11 side of the stile 9 and the vertical stile 10, whose upper end sides are connected, are connected to the grooves 9H, After being inserted and stored in the upper stile 10J, the upper slat 12B is fixed with screws from the sides of the vertical stile 9 and vertical stile 10 via the screw receiver 12d, and each stile 12A, 12B, 12C
It is fixed by screws from the side of the stile 9 and the vertical stile 10 to the screw receiving hole 13F of each connecting piece 13 that connects the stile 9 and the vertical stile 10. In addition, a lower stile 11 is assembled between the lower ends of both stile 9 and 10, and the lower stile 11
The fitting portion 12 of the lower blade plate 12C is in the groove portion 11H.
e are fitted and screwed from the sides of both frames 9 and 10 via the screw receivers 12f, thereby forming the ventilation storm door 8.

Next, the operation and effect of the first embodiment configured as described above will be explained.

Now, the ventilation shutters 8, 8' of this example include a plurality of intermediate slats 12A and upper and lower slats 12B, 12 in the frame assembly.
C are mounted with a gap T between them, and dovetail grooves 12b, 12c are formed at the upper and lower ends of each vane plate 12, and dovetail grooves 12b, 12 of adjacent vane plates 12 are formed.
c are made to face each other, and this blade plate 12
A connecting piece 13 is interposed between the opposing dovetail grooves 12b and 12c at both ends of the frame assembly, and the connecting piece 13 is inserted into the grooves 9H and 10J formed in the connecting stile 9 and vertical stile 10 of the frame assembly. Screw receiving hole 13F formed in
It is configured to be fixed with screws from the sides of the stile 9 and the vertical stile 10. Therefore,
Multiple intermediate blade plates 12A and upper and lower blade plates 1
2B and 12C are dovetail grooves 12b and 12c that face each other and are connected by a connecting piece 13, so the blade plate 1
2 can be connected extremely easily, and the connected slats 12 can be connected to the stile 9 and the vertical stile 1.
The blade plate 12 can be attached by inserting it into the grooves 9H and 10J of the connecting frame 9.
Since they are fixed with screws from the sides of the vertical stile 10, the mutual spacing T between the vanes 12 is maintained constant by the connecting pieces 13, and they can be securely fixed.

Next, FIGS. 6 to 8 show a second embodiment of the present invention, and a ventilation shutter 15 of this second embodiment is shown.
For example, the shutter 15 is installed in the form of double doors on the outdoor side, shielding only the front side of the open part 5 of the arch window frame body 1, and the ventilation shutter 15 has a rectangular shape formed by the upper stile 16, the lower stile 17, and the left and right vertical stile 18. Each stile 16, 17, 18 has a groove 1 inside it.
6A, 17A, 18A are formed, and in this frame assembly, the slats 12 of the first embodiment, that is, a large number of intermediate slats 12A and upper and lower slats 12B, 12C are connected via connecting pieces 13 to form left and right sides. It is inserted between the grooves 18A of the vertical stile 18 and attached. Therefore, this second embodiment also provides the same effects as the first embodiment.

In addition, the ventilation shutters 8, 8', 15 of each of the above embodiments
Although the present invention is exemplified with a hinged door attached to an arch window frame body in a double-folded manner, the present invention is not limited to this, and can also be applied to a general sliding door. Further, the frames and frame members illustrated in the embodiments are all formed from extruded molded materials of light alloy materials such as aluminum.

The present invention is a ventilation storm door in which a plurality of slats are attached to a frame assembly with gaps between them, and dovetail grooves are formed at the upper and lower ends of each slat, so that the dovetail grooves of adjacent slats can be connected to each other. At the same time, a connecting piece is inserted between the facing dovetail grooves at both ends of the stile, and is inserted between the grooves of the stile of the stile assembly, and the screw receiving hole formed in the connecting piece is inserted into the stile side. Since the structure is such that the screws are fixed from the stile, it is possible to connect the slats extremely easily through the connecting pieces, and by inserting the connected slats into the grooves of the stile, they can be connected in series. In particular, since the stile is fixed to the screw receiving hole of the connecting piece from the side of the stile with screws, the mutual spacing between the slats can be maintained constant by the connecting piece, and the blades can be securely fixed.
