Description

Window Locking Device {Device Locking Window}

The present invention relates to a window lock.

The present invention relates to a window lock.

In general, a window is used for the purpose of lighting or ventilation on the outer wall of a building, and the transparent or opaque glass is called a window, and the window frame is fixed along the outer circumference thereof, and the window frame can be opened and closed from the window frame. Say.

Looking at the windows, the classification varies according to the purpose, shape, structure, location, or designer, and there are many names, many functions, and not only in terms of function, but also in the design of the building. There are windows and purely decorative windows, which are classified according to the opening and closing method, which is a casement window which is opened and closed as the window joined by white paper is rotated vertically or horizontally with respect to the window frame, and the window is moved along the rail of the window frame. Sliding windows that open and close as they are typical.

Since these windows are installed in the middle part of the wall of the building, the occupant unlocks the window lock for room temperature control or ventilation, and then opens and closes the window.

1 to 2 are cross-sectional views (utility model registration No. 0371733 name; door lock) showing a conventional door lock.

Conventional door locks are attached to the fixed portion of the opening and closing door (1) and the hanging piece (2) has a locking step (2a) (2b) formed on both sides;

A stator (4) attached to the door frame (3) facing the hanging piece (2) and formed into a rectangular parallelepiped;

The stator 4 forms guide holes 40 and 41 formed at intervals capable of accommodating the hook piece 2 on the outer side, and are inserted through the guide holes to hook the hooks 5a and 6a to the outer protrusions. And support shafts 50 and 60 formed on the inner end of the support shaft, and the support shafts are pivoted on the support holes 4a and 4b formed in the stator 4, and the coil is formed between the stator inner wall and the ket. It is interposed between a pair of ketches (5) (6) and two ketches where the springs (7) (8) are fitted, and a rotating shaft (90) is formed at the center to drill a square hole (91) at the center of the rotating shaft, (9a) and (9b), and the rotor 9 whose inner and outer sides are inclined surfaces 9c and 9d contacts the inner surface of the ketches 5 and 6, and the one-side connecting rod 9b is ketches 5 The handle 10 installed on the outer surface of the door frame 3 in the central shaft hole 91 of the rotating shaft 9 of the rotor 9 by contacting the inner surface and the other connecting rod 9b is brought into contact with the inner projection 6b of the chamfer 6. To rotate the square working rod (11) Able to provide a door lock.

The door lock has a stator 4 installed inside the door frame 3 and a handle 10 mounted on an outer surface of the door frame so that the square operating rod 11 connected to the handle rotation shaft is a rotor 9 of the stator 4. When it is connected to the center square hole 91, two ketches 5 and 6 installed in the stator 4 are subjected to the repulsive force of the coil springs 7 and 8 to the inner ends of the guide holes 40 and 41. In contact, the two ketches remain in parallel.

Then, the connecting rods on both sides of the rotor 9 are installed between the hooks, so that the two hooks are kept in the working standby state. At this time, when the hook piece 2 is inserted between the hooks of the two hooks, the hook doors are closed. This inclined surface and the inner support shafts 50 and 60 are hinged to the support holes 4a and 4b of the stator, so that the coil springs 7 and 8 are compressed outwardly so that the hooks 5a and ( The masterpiece is put in between 6a).

At this time, when the hook is over the hook, the two-necked hook (5) (6) is inwardly driven by the return force of the coil spring, and the hook is caught on both sides of the hook (2a) (2b) by the hook spring. The open door is locked.

On the other hand, when the door is securely locked and the door is opened, hold the handle and rotate the operating rod 11 so that the connecting rods 9a and 9b of the rotor 9 push the inner surface of the collars 5 and 6 so that the protrusion of the collar is Since the gap between the hook (5a) (6a) is moved to the outward is to open the door by moving the opening and closing door at this time.

However, the ketches have a problem in that the tip is expanded only when the rotor is rotated in one direction and the ketches cannot be rotated when the rotor is rotated in the other direction.

Furthermore, a stator with a handle is formed on the door frame, and a latch is held on the door to open and close the locking hook, and when opening the door, one hand pulls the handle of the stator formed on the door frame to one side to release the catch of the hook. There was an uncomfortable problem of opening the door with one hand.

Thus, in the case of a user who is uncomfortable with one hand, a user may not be able to open the door, thereby causing a problem that the user's usability is impaired.

In addition, if the two doors are closed by the coil spring's repulsive force in contact with the guide hole inner end and the door is closed, the inclined surface of the door and the hook face collide, and the hook side opens and the hook side opens and the hook hook is extended. The door is locked.

However, when most of the users close the door by force rather than close it closes, the noise of the metal hits as the inclined surface and the hanging piece of the hook comes into contact.

Furthermore, since the inclined surface of the ket chuck slides on the hook piece, friction noise is generated secondarily, and when the inclined surface completely escapes the hook piece, the groove formed in the hook by the elastic force of the coil spring comes into contact with the top and bottom of the hook piece and makes a third noise. This problem occurred.

Furthermore, when the door is closed, the ket odor is not expanded by the handle, but is expanded when the claw pieces formed on the door collide with each other.

The main object of the present invention for solving the above problems is to ensure that the front end of the clamp to be caught when the handle is rotated to one side or the other side when opening and closing the window at all times to ensure that the locking hole and the latch is locked when the window is opened and It is to provide a window locking device to minimize the generation of noise by avoiding hitting.
