Problems to be Solved by the Invention In the conventional locking protrusion for the pull handle shown in Japanese Utility Model Application Publication No. 57-16466, the fixing fitting 1 is
The two pins 3 protruding from the back side of the mounting seat 2 are inserted into the pin holes 16 of the mating frame 15 (or the mullions of the mating part) for positioning. In addition to screw holes 17 for the locking metal fittings, it was necessary to provide a pin hole 16 for the locking metal fittings on the stile 15 (or the mullion of the fitting part). In existing soundproof sashes with locking metal fittings, the locking metal fitting holes are long holes so that the amount of pull of the outdoor sliding door can be adjusted. In recent years, it has become common to replace this old-fashioned locking metal fitting with the above-mentioned locking device that uses a fixed metal fitting. In order to replace the stopper with the conventional locking device for the pull handle as described above, attach a fastener for the fastener to the connecting stile or mullion or vertical frame of the indoor sliding door of the existing soundproof sash. There was a problem in that the end user could not replace the pin holes because they needed to be newly provided.

In addition, in the conventional locking device shown in Japanese Utility Model Application Publication No. 59-33965, the engaging member protruding from the front is provided separately from the holding metal fitting, which impairs the aesthetic appearance and also prevents the engagement member and the holding metal fitting from collapsing. The strength of the grip is significantly reduced, and the gap between the engaging member and the holding fitting is likely to be contaminated by dirt, making it impractical.

Means for Solving the Problems In order to eliminate the drawbacks of the conventional device described above, the present invention provides horizontally long mounting holes at the top and bottom of a mounting seat formed in a vertically long rectangular shape, and at the center of the front surface of the mounting seat. A locking projection is provided on the back side of the mounting seat, a fitting hole is provided on the back side of the mounting seat that spans the above-mentioned upper and lower mounting hole positions, and a vertical tooth portion for positioning in the width direction is formed in the deep part of the fitting hole. Attachment holes consisting of round holes or square holes that can overlap with the attachment holes of the locking metal fittings are provided at the top and bottom of the fastening metal fittings and a mounting seat formed in an elongated rectangular shape and having a width narrower than the horizontal width of the fitting holes. , consisting of a fixing metal fitting having vertical teeth formed in the front central part of the mounting seat to engage with the teeth of the locking metal fitting, so that the fixing metal fitting and the locking metal fitting can be fastened together with a set screw. It is characterized by the following structure.

Function When the locking device for the pulling handle of the present invention is installed on a soundproof sash, a screw hole for the locking metal fitting is provided in the connecting frame of the indoor sliding door, the mullion or vertical frame of the fitting part, etc. The fixing bracket and the locking bracket can be attached with just one step, and when replacing a conventional locking bracket with the locking device of the present invention, the existing locking bracket can be installed without having to provide a pin hole for the fixing bracket as in the past. This can be easily implemented by the end user by using the existing mounting holes for the locking metal fittings as they are. When installed on the soundproof sash, the teeth of the locking metal mesh with the teeth of the fixing metal, allowing for secure positioning in the indoor-outdoor direction, and the locking metal fittings can be reliably positioned indoors and outdoors. Even when the locking arm interlocking with the shifting handle is engaged with the locking protrusion of the locking metal fitting to draw the sliding door toward the indoor side, the locking metal fitting can be prevented from shifting toward the outdoor side. In addition, when in use, the fixing metal fittings can be completely covered by the locking metal fittings, and the aesthetic appearance and cleanability similar to those of conventional locking devices can be maintained. In addition, when adjusting the amount by which the sliding door is drawn, it can be easily adjusted by loosening the set screw and changing the engagement position of the locking metal fitting and the fixing metal fitting.
