Description

[Detailed explanation of the invention] In this invention, a shutter rail frame is continuously formed on the outdoor end of a metal sash into which a shoji etc. is fitted, and a vertical shutter frame is attached to both open ends of this shutter rail frame. This invention relates to a metal sash with a shutter that can be attached to either the door frame or the door frame.

The purpose of this is to make it possible to freely select either the vertical shutter frame or the door bag frame and install it on either the left or right side of the shutter rail frame, and to minimize the number of parts while being left-handed or left-handed. The point is that it makes it possible to do so.

An example of implementing the present invention will be described with reference to the drawings. Reference numerals 1 and 2 are upper and lower frames of a metal sash, which are integrally molded with storm door rail frames 3 and 4 that are open at both ends on the outdoor side.

A shoji 5 or the like is slidably fitted between the upper frame 1 and the lower frame 2, and a shutter 6 is slidably fitted between the shutter rail frames 3 and 4.

Reference numeral 7 denotes one formwork of the storm door rail frame which closes one open end of the rain door rail frames 3 and 4, and is fixed to the outdoor side end of one of the metal sash formworks 8 and 9 with screws 10.

Reference numeral 11 denotes a door bag frame that is continuously fixed to the other open end of the storm door rail frames 3 and 4, and its opening 14 is sealed by a cover 12.

That is, the door is sealed only with the cover 12 without using a separate end plate or without using bent pieces of the upper plate or lower plate of the door case body 11.

Reference numeral 13 denotes a doorstop stopper that is fitted inside the formwork 7 of the storm door rail frame, if necessary.

However, as shown in Figure 3, the general shutter 6...
- has an engaging groove 15 and an engaging protrusion 16 on both side edges, and the adjacent shutters 6, 6 are connected to each other by this engaging groove 16.
It is firmly connected by the engagement of the engagement protrusion 16 and serves to prevent it from coming off during strong winds.

On the other hand, the cover 12 has a collapse prevention protrusion 17 that engages with the engagement groove 15 of the shutter 6 to prevent the shutter 6 from falling, and a collapse prevention protrusion 17 that engages with the engagement protrusion of the shutter 6 to prevent the shutter 6 from falling. Anti-tilting grooves 18 are arranged at positions symmetrical with respect to the center point P, as shown in FIG.

Furthermore, as is clear from the cross-sectional shape in FIG. It is formed into a notch shape.

As described above, the present invention integrally forms a storm door rail frame with both ends open on the outdoor side ends of the upper and lower frames of the metal sash, and one open end of this storm door rail frame is connected to the vertical edge of the metal sash. It is closed with a vertical frame fixed to one of the outdoor ends, and a door frame is continuously fixed to the other open end, and a cover is attached to the opening so that it is sealed only with the cover. The cover has anti-tilting protrusions and grooves that engage with the engagement grooves and protrusions on the side edges of the shutter to prevent the shutter from falling, arranged in symmetrical positions with respect to the center point. and the cover has a pair of guiding tapered surface portions formed in symmetrical positions with respect to the center point so that the cover can be rotated 180° to the opening. By configuring it so that it can be installed as

(a) By simply fixing the shutter form 7 in the opposite direction,
You can choose to have the shutters open to the right or to the left.

(b) The opening 14 on the end plate side of the door bag frame 11 is sealed only with the cover 12, and the protruding strip 17 or groove 18 for preventing falling is directed inward to prevent the shutter 6 stored in the door bag from falling. With the simplest structure and minimum number of parts,
It is definitely possible.

(C) Since the cover 12 that seals the opening 14 on the end plate side of the door bag frame 11 has the tapered surface portion 19 for guiding the shutter 6 to extend, the structure can be further simplified and the number of parts can be reduced. .

(d) Since the cover 12 has the tipping prevention protrusions 17 and the tipping prevention grooves 18 arranged in symmetrical positions with respect to the center point P, either the protrusions 17 or the grooves 18 are located inside the door bag. can be selectively selected and attached to the opening 14, and regardless of which of the engagement grooves 15 and the protrusions 16 of the shutter 6 are compatible, the shutter 6 can be prevented from falling when stored in the door bag.

Therefore, the left and right handing of the door pocket is further facilitated.

(e) Since the pair of guiding tapered surface portions 19.19 are cut out at positions symmetrical with respect to the center point P,
■ Even if the shutter is turned 80 degrees, the shutter 6 can be smoothly guided when the door is extended.

Moreover, the tapered surface portion 19 on the outdoor side improves the aesthetic appearance and is preferable from a safety point of view as it does not cause any damage even when the body comes into contact with it.
