Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a sash member connecting device capable of connecting sash members at various angles.

(Prior Art and Problems Thereof) Recently, it has become necessary to connect sash members in a trapezoidal shape, a pentagonal shape, or the like, in consideration of the design of the appearance and the relationship with the surrounding members. In this case, for example, when the sash member is framed in a trapezoidal shape as shown in FIG. 7, by inserting the joint metal fitting 17 formed at a predetermined angle into the abutting portion of the hollow sash members 14, 15, 16 It was connected.

However, in the case of the conventional connection structure, since the angle of the joint metal fitting was made to correspond to that angle for each connection portion of the sash material, if there is an error in the butt angle of the sash material during construction, the joint metal fitting will be It had to be recreated, which was very inconvenient.

(Object of the Invention) The present invention solves the above problems, and in particular, provides a sash member connecting device capable of easily and reliably connecting the sash member in accordance with the butt angle of the cut ends thereof. To that end.

(Means for Achieving the Purpose) In order to achieve the above object, the sash connecting device according to the present invention cuts the ends of the hollow portion formed in the sash at an appropriate angle, and cuts the cut ends. In a sash member connecting device for abutting and connecting via a joint metal fitting, the joint metal fitting is formed by a plurality of connecting legs which are rotatable relative to each other about a support shaft, and the connecting legs are butted. It is characterized in that it is inserted into the hollow portion of and the entire joint metal fitting is housed in the butted sash material.

(Advantage of the Invention) According to the above configuration, when the cut ends of the sash member are butted and connected to each other, the connection legs of the joint fittings are rotated in accordance with the angle of the butted portion of the sash member to be connected to each other. Are inserted into the hollow portion from the cut end of the sash material to connect them. At this time, the entire joint fitting is housed in the butted sash material.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings. The embodiment shown in FIGS. 1 to 5 shows one used for a trapezoidal sash sash A. Is a sash material, and is composed of a mold material made of aluminum or its alloy,
Each of the cross sections has a hollow portion 4 formed by projecting an H-shaped portion from the middle of the base portion of the U-shaped portion. The sash member 1 constitutes an upper frame, and the sash members 2 and 3 constitute left and right vertical frames. ing.

One end of the upper frame 1 is cut at an acute angle (30 °) and the other end is cut at an acute angle (60 °), and the upper end of one vertical frame 2 is cut at an acute angle (30 °) according to the acute angle, and the other end is cut at the other. The upper end of the vertical frame 3 is cut at an acute angle (60 °) according to the acute angle.

Next, a is a joint fitting, and two pieces of connecting legs 5 and 6 are rotatably supported by a support shaft 7 so that the opening angles of both connecting legs 5 and 6 can be adjusted. Also, both connecting legs 5, 6
The female screw hole 9 of the fixing screw 8 is bored in this. Notches 10 and 10 are formed in the end portion of one of the connecting legs 6 on the shaft support side. The thickness of the joint metal fitting a is formed so that it can be fitted inside the hollow portions 4 of the upper frame 1 and the left and right vertical frames 2 and 3.

The upper frame 1 and the left and right vertical frames 2, 3 by the joint metal fitting a.
In the case of assembling a frame with a predetermined frame, a plurality of louver blades 11 having a substantially S-shaped cross section are previously installed inside the upper frame 1 and the vertical frame 3 with a gap S in the overlapping portion, and a net or the like is provided in the gap S. Pest control member 12a and valve member 12b which is opened and closed by gravity and wind force
Is provided, and one connecting leg 5 of the joint metal fitting a, which is adjusted to be opened at 30 °, is inserted into the hollow portion 4 at one end of the upper frame 1 and fastened with the screw 8, and the other connecting leg 6 is connected to the vertical frame 2. Hollow part 4 at the end
The upper frame 1 and the vertical frame 2 are connected to each other by abutting the end of the upper frame 1 with the cut end of the upper frame 1 and fixing them with screws 8. On the other hand, one connecting leg 5 of another joint metal fitting a, which is adjusted to be opened at 120 °, is inserted into the hollow portion 4 at the other end of the upper frame 1 and fixed, and the other connecting leg 6 is attached to the end of the vertical frame 3. The hollow blade 4 is inserted into and fixed to the frame, and the louver blade 11 is fixed to the frame. Also, the left and right vertical frames 2, 3
A lower frame 13 having a mold material structure is fitted to the lower end of the above and fixedly fixed to both of the vertical frames 2 and 3. As a result, the trapezoidal sashes A are formed.

In the above-mentioned glass sash A, the entire joint fitting a is housed in each hollow portion 4 of the upper frame 1 and the vertical frame 2 or the upper frame 1 and the vertical frame 3 which are butted. Further, since the connection leg 6 of the joint metal fitting a is formed with the notches 10 and 10, burrs at the time of cutting formed at the ends of the butted frames 1 and 2 (the acute angle side of 30 °). You can escape and avoid rattling.

Next, another embodiment will be described with reference to FIG. The glass sash B according to this embodiment includes two upper frames 1'and 1 ', both ends of which are cut at 60 degrees, and left and right vertical frames 2', 3'and a lower frame 13 'of which only upper ends are cut at 60 °. The front shape is framed by a pentagon.

Also in this case, as in the case of the above-mentioned embodiment, the upper blades 1 ', 1'and one of the vertical rails 3'are preliminarily attached with louver blades 11' having an S-shaped cross section, and the upper rails 1 ', 1' Insert the connecting legs 5 ', 6'of the joint metal fitting a'opened and adjusted to an obtuse angle (120 °) into the end of the abutting part of, and screw them together, and connect the vertical frame 2'to the other end. 3'is connected by a joint metal fitting a'which is opened and adjusted at an obtuse angle in the same manner as described above, with the ends thereof abutted, the louver blades 11 'are screwed in a predetermined manner, and both vertical frames 2', 3 ' Lower frame 1 at the bottom of ′
3'can be screwed to form a framework.

By connecting the sash members in the same manner as described above, any connection angle of the sash members can be immediately dealt with. Further, there may be three or more insertion legs.
Of course, it can also be applied to the connection of sash materials other than sashes.

(Effects of the Invention) According to the sash member connecting device of the present invention, the connecting legs of the joint fittings inserted into the hollow portions of the cut ends of the sash members when connecting the sash members are mutually rotatable. Therefore, even if the sash members to be connected have any butt angle, and even if there is some error in the cutting angle at the time of construction, the sash members can be easily and reliably connected. Further, since the entire joint fitting is housed in the butted sash members and hidden from the outside, the appearance of the connected sash members is not impaired.
