Abstract

The present invention relates to a hook operation structure of a locking device for a sliding door. In regard to the composition of the present invention, when a rotor (11) is rotated with a handle (21) by a predetermined angle, an inclined pushing surface (11a) forcedly pushes a transfer protrusion part (12) provided on a slide bar (1d) by a predetermined distance as an operation piece (11') integrated with the rotor (11) is also rotated. At this time, as soon as a latch protrusion (13) bearing a placement protrusion (h1) of a hook (h) departs from the placement protrusion (h1), a restoration force of a compression spring (s2) instantaneously actuates an unlocking piece (14) to push an unlocking push piece (h2) such that the hook (h) is unlocked. When a window is closed, as a protrusion part (h3) of the hook (h) is pushed due to contact with a striker early, the hook (h) is pushed in a direction opposite to the unlocking operation while pushing the unlocking piece (14), and, simultaneously, as the hook (h) is rotated in a direction opposite to the unlocking operation, the latch protrusion (13) provided at the end of the slide bar (1d) can bear the placement protrusion (h1), thereby making a stable change to a locked state. According to the present invention, since an existing torsion spring is not mounted on the hook (h), there can be productivity increase and cost reduction effects due to an excellent assembly property, and also, the hook can stably perform locking and unlocking operations without the torsion spring, thereby bringing about various effects such as the obviation of a failure risk, excellent durability and the like.

Description

Hook operation structure of locking device for sliding window

In an automatic locking device for sliding doors and doors, the present invention enables assembling of a hook mounted on a keeper without elastic parts such as torsion springs, while allowing the fastening and disengaging functions of the hook to be performed with reasonable precision, resulting in reduced parts It relates to a hook operation structure of an automatic locking device for sliding doors and windows in order to increase performance, increase productivity, and significantly reduce costs, and thereby maximize durability and reliability of the automatic locking device.

As is well known, most sliding windows, such as windows, living rooms, verandas, and windows in houses or apartments, are equipped with automatic locking devices.

The automatic locking device includes a keeper embedded in the window frame and a handle assembly installed outside the window frame to interlock the keeper. When the window or door is slidably closed, it is automatically locked, and holding the handle. If you push or pull while rotating in the direction you want to open, it is unlocked and the window or door can be opened.

On the other hand, in the configuration in which two-point or one-point locking is made, the keeper is configured to be spaced apart from the main body and the hook assembly, so that the rod sliding by the rotor releases the hook, Patent Document 1 (Republic of Korea Patent No. 10-2002311) No.) and Patent Document 2 (Republic of Korea Patent No. 10-2063732), the hook assembled by the hinge on the hook assembly is mounted together with the torsion spring, and at this time, the rod moving linearly by the rotor is together with the compression spring. It is installed and acts to forcibly disengage the stop block to keep the hook in a locked state.

Therefore, when the rotor is rotated by turning the handle, the rotor slides and transports the rod to forcibly press the stop block hung in the stop groove on the bottom of the hook, and accordingly the stop block coupled to the bottom of the hook to maintain the locked state. As it is separated from the hook, the hook is rotated and released by the restoring force of the torsion spring.

Also, when an open window or door is closed, the jaw part of the hook, which has been locked in the unlocked state by the torsion spring, first collides with the striker. At this moment, the hook rotates and gets caught by the striker, and at the same time, the stop block is caused by the compression spring. The automatic locking is achieved as it is hung on the bottom surface of the hook by the restoring force of the and supported, and a torsion spring with strong restoring force is also installed in the rotor in the above configuration.

However, in the conventional locking device configuration, the hook assembled to the hook assembly must be assembled together with the torsion spring to operate, and the stop block for controlling the hook is also complicated in its system and has a large number of parts, resulting in poor assembly. Problems followed, and the torsion spring mounted on the hook may change and deform in the process of using it for a long time, resulting in a significant decrease in reliability.
