Description

[Detailed description of the invention] (Field of industrial application) The present invention is installed in sliding fittings such as sliding windows and sliding doors, and when the glass doors of sliding windows and sliding doors are closed, This invention relates to a locking mechanism for fittings that is automatically locked.

(Prior Art) In general, locks of various structures are installed on fittings attached to entrances and windows of buildings such as residential houses and buildings for security purposes.

By the way, all conventional locks installed on fittings had to be operated manually. As a result, they often forgot to lock their locks when they went out, leaving the fittings unlocked when they went out, and were extremely careless.

On the other hand, in recent years many aluminum and stainless steel sashes have been used for building windows. As shown in FIG. 8, this is a window frame 15 fitted into an opening in a wall.
It consists of two glass doors 16 that are slidably fitted in the window frame 15 in the left and right directions, and a lock 17 that locks the glass doors 16, and is watertight.
It has excellent airtightness and sound insulation properties.

However, even in the above-mentioned Satsushi, since the lock is manually operated, the above-mentioned drawbacks have not been improved in any way.
There was a security problem.

(Problem that the invention aims to solve) This invention was devised to solve the above problems, and its purpose is to automatically lock sliding fittings when they are tightened. To provide a locking mechanism for fittings.

The present invention has an actuating body 5 which is provided at a corner of a sliding fitting so as to be movable along the moving direction thereof, and which has a through hole 5a in the middle thereof in a direction perpendicular to the moving direction; a first elastic body 6 whose part is biased so as to constantly protrude outward from the fitting; provided at a corner of the fitting in a direction perpendicular to the moving direction of the actuating body 5;
A support tube 14 having a cut groove 10a in the wall; is provided inside the support tube 14 so as to be movable up and down, and when the sliding fitting is opened and the actuating body 5 is in a protruding state, it is locked to this and is not protruded. When the operating body 5 is held in this state and the sliding fitting is closed and the operating body 5 is in a non-protruding state, the through hole 5a of the operating body 5 is
A locking body 7 that is inserted through the fixture, a part of which protrudes from the fixture, and fits into a recess 9 formed in the fixture frame; a support cylinder 1;
4; a second elastic body 8 which urges the locking body 7 so that a part thereof protrudes outward from the fittings; and an operating means 10 which changes the locking body 7 from a protruding state to a non-protruding state.
This is the basic structure of the idea.

(Function) In the locking mechanism, when the fitting is open, the actuating body protrudes outward from the fitting due to the urging force of the first elastic body, and the locking body is locked to the actuating body and held in a non-protruding state. ing. As a result, the fittings become movable along the fitting frame.

In addition, when the locking mechanism is tightened, the operating body is pushed by the fitting frame and becomes a non-projecting state, and accordingly, the locking between the operating body and the locking body is released, and the locking body moves to the first position. Due to the biasing force of the second elastic body, it projects outward from the fitting and is fitted into the recess of the fitting frame. As a result, the fittings are automatically locked and cannot be moved.

On the other hand, when unlocking the fittings, the locking body is changed from the protruding state to the non-protruding state by the operating means. This releases the engagement between the locking body and the recess, allowing the fitting to be opened.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a schematic front view of a sliding window sash equipped with a locking mechanism for fittings according to an embodiment of the present invention, in which 1 is a window frame (fittings frame), and 2 is a glass door (fittings). , 3 is a lock, and 4 is a lock mechanism.
