Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lattice stopper for an aluminum sash window.

[0002]

2. Description of the Related Art Heretofore, there has been a fastener found in Japanese Utility Model Publication No. 60-476 as a metal fitting for attaching a surface lattice to an aluminum sash window. Since some of them are thickly projected for reinforcement, the stopper metal fittings of the above-mentioned invention cannot open and fix the opening because the tip of the opening is in an expanded state.

[0003]

Therefore, the present invention eliminates such drawbacks of the conventional products, and securely attaches and fixes the surface lattice even to an aluminum sash having a protruding portion with a thick end portion of the side frame portion. The purpose of the present invention is to provide a fastener that can be used for any purpose.

[0004]

DISCLOSURE OF THE INVENTION The present invention is a metal fitting for attaching a surface lattice to a window sash, and the tip of the rising portion of the metal concrete which is substantially L-shaped is curved outward in a substantially inverted J-shape. The terminal point of the hooking leg portion is located inward of the center of the hooking leg portion of the curve.

[0005]

[Function] Since the bent hooking leg part of the main body is fixed to the surface lattice in advance, the leg part is long and elastic, so if you try to stop this metal part in place in the window sash, The closed end of the stop leg opens and hangs over a predetermined side frame of the sash for fitting. At this time, the inner base of the latch leg strongly contacts the thick protrusion of the side frame end.

Further, since the tip of the end of the latching leg strongly abuts on the inner side surface of the side frame of the sash, the outside of the latching leg of gold concrete has its inner base relative to the protrusion. Further, the distal end portion applies elastic force to and presses the inner surface of the side frame portion, and the surface lattice is attached and fixed to the window sash by such means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 1 is a window sash, 2 is a side frame portion formed on the outer edge of the window sash 1, and a thick protrusion 3 is formed at the end of the side frame portion.

Reference numeral 4 is a surface lattice, which is composed of a horizontal rail 5 and a vertical rail 6.

Reference numeral 7 is a stopper plate having a substantially L shape as a whole, and a base portion 8 of the stopper plate is preliminarily fixed to a part of the cross rail 5 of the surface lattice 4.

Reference numeral 9 is a rising portion of the stopper concrete 7, and a tip portion of the rising portion is formed into a swelling shape, and further forms a curved hooking leg portion 10 having a substantially inverted J shape which is extended further. To do. The entire latch leg portion 10 is bent inward (toward the rising portion), and the end points 11 of the latch leg portion are located inward from the curved center point.

The end portion of the hooking leg portion is shaped so as to always close the curved space portion.

[0012]

[Effects of the Invention] When a curved hook retaining leg portion of a concrete stopper is fitted against a thick protruding portion provided at an end portion of a side frame portion of an aluminum sash, the inner base portion thereof is in contact with the protruding portion. While contacting and pressurizing this, the end part comes into contact with the inner side surface of the side frame part and repulsively presses it strongly, so that the clasp concrete latches by the pressurizing force at the two points inside and outside. The legs are completely closed and can be securely restrained and supported.

Therefore, the clasp concrete to which the surface lattice is attached can be firmly fixed to a predetermined portion of the window sash.
