DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a door car,
In particular, the present invention relates to an anti-sway device for an aluminum sash which is easy to mount in the art of anti-sway technology for aluminum building sashes.

[0002]

2. Description of the Related Art Conventionally, as a screen door sash made of aluminum, as shown in FIG.
Notches 53, 53 are formed as a structure in which a slide plate 52, which is rotatably mounted on a shaft, is mounted at a height adjustable, and female screws of a screw receiving back plate 54 arranged on the back side of the lower frame 50 member. Elongated holes 56, 55
Each of the fastening screws 57, 57 inserted through the screw 56 is screwed into each other and firmly fastened.

That is, when a door roller is mounted, notches 53, 53 are previously formed in the lower frame 50, and the notches 53, 5 are formed.
3, a sliding plate 52 on which the door roller 51 is provided is fixed by a screw receiving back plate 54 and fastening screws 57, 57, and when the fastening screw 57 is tightened, the sliding plate 52 is output. Is determined, and the door wheel 51 is adjusted to move in and out to adjust the sash steadying.

[0004]

For this reason, not only must the notch 53 be machined in the lower frame 50 of the sash, but also the screw receiving back plate 54, and the work of adjusting the amount of movement of the door wheel 51 has a problem that the workability is very poor.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and simply attaches a member having a door roller to a lower frame of a sash to complete the installation of the door roller, thereby improving workability and adjusting the door pull-out movement. It is an object of the present invention to provide an aluminum sash swing-stopper with a new structure that can easily perform the above operation with a single screw.

[0006]

According to the present invention, there is provided a swing and swing door device for an aluminum sash having a folded structure having an inwardly facing pot-shaped cross section at the lower end of a substrate portion, which is driven from the lower end of an aluminum sash lower frame. And a fixing member having a hitting-type fitting structure for externally pressing and fixing to the end edge thereof, and a vertically movable slidably supported with respect to a substrate portion of the fixing member. One end is rotated with respect to the bearing hole between the sliding member rotatably mounted on the shaft and the female screw or the bearing hole formed on the fixed member and the bearing hole or the female screw formed on the sliding member. An adjustment screw movably mounted on the shaft is screwed and connected to the female screw, and the rotation of the adjustment screw expands and contracts the distance between the female screw and the bearing hole to displace the relative position of the sliding member in the vertical direction with respect to the fixed member. Doors to adjust the amount It is an Abstract that consisted Amount adjusting mechanism.

In addition to the above structure, the lower end of the sliding plate of the sliding member is bent in the frontward direction into a crank cross-sectional shape, and is bent downward immediately outside so as not to obstruct the rolling surface of the door wheel, The gist of the present invention is that a slip-off preventing piece that is engaged with the inside of the sash window frame lower rail is formed.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 show a preferred embodiment of an anti-vibration door system for an aluminum sash according to the present invention. Reference symbol a denotes a lower frame of the aluminum sash, and the door roller device of the present invention is fixed to the lower frame a.

Reference numeral 1 denotes a fixed member, and reference numeral 2 denotes a sliding member. A door roller 3 provided on the sliding member 2 is extended and retracted by an adjusting screw 4 interposed between the fixed member 1 and the sliding member 2. Is configured to constitute the door pulling-out amount adjusting mechanism 5 for adjusting the distance.

The fixing member 1 has a folded structure having an inwardly facing pot-shaped cross section at the lower end of the substrate portion 11, and is driven from the lower end of the lower frame a to be externally pressed and fixed to the edge thereof. The slide guides 13, 13 which slidably hold the slide member 2 slidably in the vertical direction and which are located outside both side ends of the substrate portion 11, are opposed to each other.

The sliding member 2 is in close contact with the surface of the substrate portion 11 of the fixed member 1 with both side edges of a sliding plate 21 as sliding edges 22, and slides along sliding guides 13. The door wheel 3 is rotatably mounted on a door shaft 31 erected in the middle of the sliding plate 21 so that the door 3 is cantilevered so that the peripheral edge protrudes from the lower edge of the sliding plate 21. It is provided in.

Reference numeral 23 designates a lower end of the sliding plate 21 so as to protrude from the opening 24 to an outer peripheral portion of the door roller 3.
It is an anti-separation piece bent in the shape of a crank section in the front direction. The anti-separation piece 23 is bent downward immediately outside the door roller 3 so as not to hinder the rolling surface of the door roller 3, and is provided with a lower rail of an aluminum sash window frame. b.

The fixed member 1 and the sliding member 2
The upper end of the adjusting screw 4 screwed into the female screw 14 having the upper edge bent and screwed in the screw hole is rotatably mounted on a bearing hole 25 formed by bending the upper edge of the sliding constant 21. (Only the rotation is allowed and the bearing is used.)
The rotation of the adjusting screw 4 expands and contracts the interval between the female screw 14 and the bearing hole 25 to constitute a door wheel retracting / adjusting mechanism 5 that acts to displace the vertical position of the sliding member 2 with respect to the fixed member 1. are doing.

This displacement causes the knock-in type fitting structure 12
The door roller device integrated with the lower frame a of the sash can adjust the amount of movement of the door roller 3 from the lower end, and acts to adjust the swing of the aluminum sash by adjusting the door contact with the lower rail b. I do.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the description of the above embodiment, the door end retracting / adjusting mechanism 5 bends the upper edge of the substrate portion 11 of the fixing member 1 and is screwed to the female and female child 14 having a screw hole formed therein. Is screwed and connected to a bearing hole 25 formed by bending the upper edge of the sliding plate 21 of the sliding member 2 so as to be rotatable. Even if the position of 25 is reversed, the position of the sliding member 2 in the vertical direction with respect to the fixed member 1 can be displaced by the rotation of the adjusting screw 4 screwed and connected therebetween. That is, while the adjustment screw 4 has a bearing structure on the substrate 11 side, the sliding member 2
The side is screwed with the adjusting screw 4 as the female nude 14.

[0016]

As described above, the swing-stopper for an aluminum sash according to the present invention has a folded structure having an inwardly facing pot-shaped cross section at the lower end of the substrate portion, and is driven by tapping from the lower end of the lower frame. The sash-type fitting structure, which is externally pressed and fixed to the edge, allows the sash to be integrated into the sash by simply tapping it into the lower frame. Be improved.

Further, the fixing member and the sliding member are screwed and connected by a structure in which a shaft end of an adjusting screw screwed to the female screw on the fixing member side is rotatably mounted in a bearing hole on the sliding member side, Since the vertical relative position of the sliding member with respect to the fixed member is displaced by the rotation of the adjusting screw, the amount of movement of the door stroller from the lower end of the door stroller device can be easily adjusted. It has features such as easy adjustment of run-out, and the effect obtained by implementing the present invention is extremely large.
