Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a device that makes it possible to easily, tightly and firmly fasten the corners of the vertical and horizontal edge frames of an aluminum sash.

[Conventional technology]

Conventionally, most of the connecting devices for the corners of the vertical and horizontal edge frames of this type of aluminum sash are made by connecting the beveled edges formed at the ends of each edge frame, and then attaching an angle fitting to the connecting part. A washer is interposed on the outer surface of the insertion hole drilled in each piece of the angle fitting, and the insertion hole of each of the above two pieces is aligned with each insertion hole and screw hole of the washer and edge frame, and a screw is inserted into each insertion hole and screw hole. It is screwed into a skewer.

However, if such a method is used, the positions of the insertion holes in each edge frame corner, the insertion holes in both pieces of the angle bracket, and the screw holes in the washer tend to be mismatched, and therefore, in this case, it becomes impossible to screw the parts together, or if they are screwed together, Also, gaps tend to form between the respective diagonal edges of the frame corner, and the cuts of the diagonal edges forming the corner are exposed, resulting in an unstructured structure, and the bond strength is weak, making it difficult to assemble firmly and stably. Therefore, great pains were required in determining the positions of the holes, screw holes, angle metal holes, etc. in the corners of the edges of the frame. Therefore, in order to avoid this disadvantage, there is a device in which the insertion hole in each edge frame corner is made into a long hole, but in such a device, the screw tends to slide gradually due to vibration or impact after screwing, so it is not stable. Such a combination is impossible.

[Problem to be solved]

The present proposal is vertical in order to eliminate the existing disadvantages mentioned above.
After the corners of the horizontal edge frames are connected by aligning the insertion holes and screw holes of each edge frame itself, angle fittings, etc., and eliminating the screwing means, and joining the diagonal edges at the ends of the vertical and horizontal edge frames. The purpose is to easily, yet firmly and tightly connect them using a separate member.

[Means to solve]

In other words, the upper central half (or lower half) of a substantially rectangular plate is cut from the upper edge (or lower edge) to the middle part, and the tongue piece is bent inward at a right angle and the upper (or lower part) on both sides of the tongue piece. A male metal fitting provided with a sleeve piece with each insertion hole, a recess cut out in a shape that fits the tongue piece of the male metal fitting in the front half of the center of the approximately rectangular plate, and a recess cut out in a shape that fits the tongue piece of the male metal fitting, and a front end on both sides of the recessed recess, respectively. Each upright piece with a screw hole is provided with a female metal fitting that stands vertically above (or below), and after joining each diagonal edge on the inside of each end of the vertical and horizontal frame, Fix the base of the male metal fitting to the outside of the end of the edge frame with its tongue overlapping the outer surface of the end of the edge frame in the horizontal direction, and then attach the base of the female metal fitting to the outer surface of the end of the edge frame in the horizontal direction. After fixing with the tongue piece of the male metal fitting interposed in the recessed notch, insert a screw into the threaded hole of each upright piece of the female metal fitting through the insertion hole of each sleeve piece in the male metal fitting and tighten it. This is used to fasten the corners of the aluminum sash.

[Effect]

In this case, after the beveled edges of each end of the vertical and horizontal edge frames are joined together, the base of the male metal fitting is attached to the outside of the end of the vertical edge frame, and its tongue piece is attached to the edge of the horizontal edge frame. Since it is fixed in a superimposed state on the upper (or lower) surface of the part, it can always be easily attached.Also, when attaching a female fitting to a horizontal edge frame, the tongue piece of the male fitting is interposed in the recessed part. Since each of the upright pieces faces both sleeve pieces of the male fitting, if screws are inserted through the respective holes in both sleeve pieces, these screws will fit into each of the upright pieces. It is screwed into the screw hole in the piece and fastened firmly and tightly.

Since the present proposal is as described above, there is no need to drill holes in advance near the joints of the vertical and horizontal edge frames or to match each insertion hole and screw hole in order to fasten the corners, as in the conventional method. This invention is extremely advantageous as a corner fastening device for aluminum sashes, since it is possible to perform simple, efficient, and effective fastening without becoming unable to fasten the holes, and without having to worry about the location of the holes.

〔Example〕

In a device for forming a corner by joining the inner beveled edge S at the end of the vertical edge frame 3 and the inner bevel edge S' at the end of the horizontal edge frame 4 in an aluminum sash, the upper end of the vertical edge frame 3 (or lower end) on the outer surface,
A tongue piece T that is cut in the upper half (or lower half) of the center of the wide edge side of a substantially rectangular plate from the upper edge (or lower edge) to the middle part and bent inward at a right angle to protrude. The base 1' of the stainless steel male fitting 1, which has sleeve pieces U and U with insertion holes H perforated in the upper (or lower) sides of both sides, is connected to the edge of the edge frame 4 in the lateral direction. At the same time, screws P are inserted and fixed through welding or pre-drilled screw holes while superimposed on the upper surface (or lower surface) of the upper surface (or lower surface) of the edge frame 4 in the horizontal direction. The base of the female metal fitting 2 is provided with a recessed part R cut out in a shape that fits the tongue piece T of the male metal fitting, and each upright piece E with a screw hole N bored at the front end of both sides of the recessed notch. 2' is fixed in the concave notch R with the tongue piece T of the male metal fitting 1 interposed therein by welding or with a screw P' inserted through a previously drilled screw hole, and then both sleeve pieces U of the male metal fitting 1 are fixed.
Each screw 5 inserted through each insertion hole H is screwed into each screw hole N of each upright piece E in the female fitting 2, and X in the drawing indicates the clearance existing between the male and female fittings. be.
