DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner connecting device for a deformed sash and a method for connecting a corner of a deformed sash in which at least one corner forms an angle other than a right angle.

[0002]

2. Description of the Related Art Conventionally, as a corner connecting device for a deformed sash, as shown in FIGS. 6 (a) and 6 (b), two ends of two connecting legs (a) and (b) of a rectangular plate are mutually connected. First, a pair of frame members (E) are used by using a joint fitting (D) which is openably and closably connected by a support shaft (c) in a state where the plate surfaces are overlapped.
At the same time, the oblique joining ends (m) and (n) of (F) are brought together, and the connecting legs (a),
(B) is a hollow part (g) of the frame materials (E) and (F);
(H) Insert each connecting leg (a), (b) with the plate surface facing at right angles to the indoor and outdoor directions, and insert screws (i),
A corner connection device fixed in (j) is known (Japanese Utility Model Laid-Open No. 3-105581).

However, in the above-described conventional connection device, the overlapping tip portions of the connecting legs (a) and (b) and the support shaft (c) in the joint fitting (D) are particularly shown in FIG. In the hollow portions (g) and (h), the frame members (E),
When the sheared or joined surfaces (X) of (F) are subjected to shearing or twisting as shown by arrows (L) and (M) in the same figure, the two beveled joined ends (m) and (n) become There was a disadvantage that they were easily shifted from each other or easily separated.

SUMMARY OF THE INVENTION An object of the present invention is to improve the contact strength of a beveled end. As a means for achieving the object, a hollow portion is provided and an outer portion is provided in the hollow portion. Each joint end of a pair of frame members provided with a hole for a stopper which is opened from is beveled at an appropriate angle, and a pair of connection arms having a hole for a stopper at a position corresponding to the hole for the stopper of the frame material. A pair of connection arms are inserted into the hollow portion from the joint ends of the pair of frame members, respectively, using corner connection fittings that are openably and closably connected at one end thereof, and the beveled ends of both frame members are joined together. In the step of inserting and fixing a screw or a rivet from the stopper hole of the frame member to the stopper hole of the connection arm, the stopper hole of the connection arm is more corner than the stopper hole of the frame member. Slightly eccentric to the connection The inner peripheral surface of the hole for the stopper of the frame is set so that the corner is slightly shifted to that of the hole for the frame material stopper, and the frame is displaced to the corner when the screw or rivet is inserted. We propose a method of connecting corners of odd-shaped sashes, in which the beveled edges of both frame members are brought into close contact.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, a curtain wall made of aluminum sash windows is formed on the side of a building having a curved roof (R). Among the windows along the curved roof (R), various irregular sashes are provided. The following describes an example in which the present invention is applied to a corner connection structure of a modified quadrangular sash (S).

FIG. 2 shows a connection structure of the upper right corner at a corner angle of 64 degrees in the irregularly shaped sash (S). First, each of the joining ends (3) of the vertical frame member (1) and the inclined upper frame member (2), (4) is cut obliquely to an angle (32 degrees) that is one half of the corner angle.

The corner connection fitting (5) is shown in FIG.
As shown in (b), two rectangular plates having the same width as the inner widths of the hollow portions (8) and (9) in the indoor and outdoor directions of the vertical frame material (1) and the inclined frame material (2). Connecting arm (6),
One end of (7) is hingedly connected by a support shaft (10) having the same length as the width of the connection arms (6) and (7) so as to be openable and closable, and both connection arms (6) and (7) Are provided with female screw holes (11)..., (11).
The holes for the stoppers of the vertical frame member (1) and the inclined frame member (2) are provided on the outer walls (13) of the hollow portions (8) and (9) of each frame member.
In (14), screw through holes (16), (16) are provided at positions corresponding to the female screw holes (11), (11).

The pair of connection arms (6) and (7) of the corner connection fitting (5) are opened at substantially corner angles, and a spacer block (e.g., an elastic material such as rubber or synthetic resin) 12) and (12) are adhered, and these connecting arms (6) and (7) are oriented with their plate faces parallel to the indoor and outdoor directions and their spacer blocks (12) and (1).
2) is wedge-inserted into the hollow portions (8) and (9) of the vertical frame member (1) and the inclined frame member (2) with the inner side facing the inside. Each connection arm (6), (7) is a spacer block (12),
By (12), the outer walls (13) and (14) of the hollow portions (8) and (9) are respectively pressed against the inner surfaces of the hollow portions (8) and (9) to be in a temporarily fixed state.

Next, the outer walls (13) and (14) are threaded with the oblique joining ends (3) and (4) of the vertical frame member (1) and the inclined frame member (2) brought into contact with each other. Hole (1
6) ..., (16) ... and screws (15) ..., (15) ... to female threaded holes (11) ..., (1) in connecting arms (6), (7).
1) Screw each in.

By screwing as described above, as shown in FIGS. 2 and 3, the entire lengths of both connecting arms (6) and (7) and the support shaft (10) cannot be moved in the indoor and outdoor directions, and the hollow portion is formed. (8), (9), both beveled ends (3) and (4) are easily displaced or separated when sheared or twisted on the mating surface (X) due to wind pressure or the like. I will not do it.

In this case, the outer walls (13), (14)
As shown in FIG. 5, the relationship between the screw hole (16) and the screw holes (11) of the connection arms (6) and (7) is as shown in FIG. As shown in the figure, the inner peripheral surface of the female screw hole (11) is slightly offset (1 mm) closer to the corner than the hole (16) (4.1 mm diameter) with respect to the inner peripheral surface of the screw through hole (16). The corners are slightly offset. With this configuration, when the screw (15) is screwed into the female screw hole (11) through the screw through hole (16), the corner of the screw through hole (16) is formed by the screw (15). Direction, thereby the beveled joint end (4) of the frame material (2)
To the beveled joint end (3) of the other frame member (1),
Strengthening the contact between both joint ends (3) and (4).

The other corners of the deformed sash (S) are also connected in the same manner as described above using the connection fitting (5).

As a fastener used in the method for assembling the modified sash of the present invention, a pop rivet can be used instead of the screw (15) in the above example. It may be a rivet through hole.

[0016]

According to the method for connecting a corner of a deformed sash according to the present invention, the frame material is displaced to the corner by inserting a screw or a rivet so that the beveled ends of the two frame materials are brought into close contact with each other, so that a firm joining can be achieved. It can be formed, and the corners can be connected at any angle of the frame material, so that only one type of fastener is required and it is economical.
