Description

Locking device for sliding windows with damping function}

The present invention relates to a locking device for sliding windows, and more specifically, to a locking device that not only locks or unlocks a sliding door that opens and closes by sliding on a window such as a veranda, but also absorbs shock that may occur during the locking process. /This is about a “locking device for sliding windows with a damping function” that can be suppressed.

In general, sliding windows are opened and closed by installing a door that slides along a rail on a square window frame. The door frame closes by contacting the window frame and opens when the door frame separates from the window frame. These sliding windows have a structure in which the door opens and closes by sliding, and with improvements in window technology, sliding by rollers is done smoothly and quickly with little force without deceleration. Recently, windows and doors, which have become increasingly heavier for reasons such as insulation, open and close due to their own inertial force. In the process, it collides with the side of the window frame or another window (window) at excessive speed, generating impact noise, and frequently causes safety accidents in which the body, such as fingers or toes, gets caught in the door gap. To solve this problem, a damper assembly that induces the door to close slowly and smoothly in a sliding window was recently disclosed in Korean Patent Registration No. 10-2519537 (title of the invention: Damper assembly for sliding windows). However, the damper assembly for sliding windows described above requires specialized construction work because each component is installed separately on the door frame (window) and the window frame (window).

It is for this purpose.

<Description of the configuration of a locking device for sliding windows with a damping function according to the present invention>

The locking device for sliding windows with a damping function according to the present invention is installed on a 'sliding window' in which a door frame with a rail groove is opened and closed by sliding along the rail of the window frame; When the door frame is closed by contacting the window frame and the handle is rotated a predetermined angle in the opening direction, the locking state is released and the door can be opened.

Referring to Figures 1 and 2; The locking device 400 for a sliding window equipped with a damping function according to the present invention includes a keeper 410 fixedly installed on the inside of the window frame 100, and is mounted vertically on the inside of the door frame 200 and has an external body. It consists of a housing 420, a rocker 430 arranged to be movable in the vertical direction on the inner side of the housing 420, a coil spring 440 that elastically supports the rocker 430 in the upward direction, and a housing 420. ) is roughly divided into a rotation cam 450 for operating the locker 430 and a damping means 500 that exerts a damping force just before the locking operation of the locker 430. Each component that forms the locking device 400 for sliding windows is made of metal, and their detailed structures are as follows.

First, the keeper 410 is firmly mounted on the inner part of the window frame 100 through a screw (not shown), as shown in FIG. 1, and a locking jaw 432, which will be described later, is hung below the keeper 410 to lock it. A locking hole 411 is formed to maintain the state.

And, as shown in Figures 1 to 3, the housing 420 is mounted vertically on the inside of the door frame 200 corresponding to the keeper 410 at the top and bottom through fixing screws (not shown), and inside The component installation space 421 is formed in the vertical direction. In this housing 420, the rocker 430, coil spring 440, rotation cam 450, damping means 500, etc. can be accommodated and operated.

As shown in FIGS. 2 and 3, the locker 430 is arranged to be movable for a certain period in the vertical direction in the component installation space 421 of the housing 420, and a locking hole 431 is formed on one side. . On the outside of the lower end of the locker 430, a hook-shaped locking jaw 432 that can be selectively inserted into and removed from the locking hole 411 of the keeper 410 as it moves up and down protrudes upward. Therefore, when the door frame 200 is closed in contact with the window frame 100 and the locker 430 is raised, the locking jaw 432 is received in the locking hole 411 of the keeper 410 and is in a locked state, and the locker ( When 430 goes down, the locking jaw 432 comes out of the locking hole 411 of the keeper 410 and the locking state is released.

The coil spring 440 elastically supports the rocker 430 in the upward direction as shown in FIGS. 2 to 4. The upper end is fitted and coupled to the lower end of the rocker 430, and the lower end is located in the component installation space 421. supported on the floor. Accordingly, when the external force caused by the rotation of the rotary cam 450 is removed, the rocker 430 maintains an upward position due to the elastic restoring force of the coil spring 440.

As shown in FIGS. 2 to 4, the rotation cam 450 is used to rotate the locker 430 while rotating by the handle shaft 300 (see FIG. 1) connected to the handle (not shown), and the housing 420 ) It is accommodated and placed in the component installation space 421, and the handle shaft 300 is inserted and coupled thereto to rotate by the handle shaft 300. The outer wall of the rotary cam 450 is provided with a movable piece 451 that is received and hung in the locking hole 431 of the locker 430. Therefore, when the handle shaft 300 is rotated in the opening direction, the movable piece 451 rotates and the locker 430 is pulled downward for a certain section to release the locking state of the locking jaw 432. A torsion spring (not shown) is installed in the rotation cam 450, so that the rotation is restored to its initial state when the handle is released.

The unexplained symbol '460' is a button member for controlling the rise of the rocker 430. This button member 460 is elastically supported inside the housing 420 in the direction of the keeper 410 through a spring 461. Therefore, when the sliding window (door) is closed and the button member 460 moves backward in contact with the keeper 410, the locker 430 can rise, and the sliding window (door) is opened so that the button member 460 moves backwards to the keeper 410. ) and moves forward, the rise of the rocker 430 is restricted and it remains in a downward state.

Meanwhile, as shown in FIGS. 2 to 4, the damping means 500 includes a damper 510 disposed longitudinally in the component installation space 421 of the housing 420, and a component installation space of the housing 420. (421) It is defined as a link-type pressing member 520 capable of rotating at a predetermined angle by engaging a shaft 521 in the middle portion, and a damping roller 530 disposed at the outer end of the link-type pressing member 520. The damper 510 is an oil damper that can reduce shock through hydraulic pressure, and is disposed in the longitudinal direction at the upper part of the component installation space 421 of the housing 420, and an operating rod 511 that moves forward and backward extends and protrudes downward. In addition, a restoration spring 540 is disposed outside the operating rod 511 of the damper 510 to restore the link-type pressing member 520 to its initial state along with the operating rod 511. When the external force is removed from the damper 510, the operating rod 511 comes out in the forward direction (downward direction in the drawing) due to the elastic support force of the restoration spring 540. The link-type pressing member 520 is capable of rotating at a predetermined angle by combining the central upper part of the component installation space 421 of the housing 420 with the axis 521, and its inner end is the operating rod of the damper 510 ( 511) A shaft 522 is coupled to the tip, and the outer tip extends outside the housing 420, so that the operating rod 511 of the damper 510 can be moved backward when rotating in the forward direction. The damping roller 530 is disposed at the outer end of the link-type pressing member 520, and the locking jaw 432 of the locker 430 is inserted into the locking hole 411 of the keeper 410. ), it is pushed into the housing 420 component installation space 421 and rotates the link-type pressing member 520 in the forward direction. Accordingly, the link-type pressing member 520 moves the operating rod 511 of the damper 510 backward to exert a damping force, which will be explained in detail in the operation description.

<Description of the operation and effects of the locking device for sliding windows with an auxiliary opening function according to the present invention>

Next, the operation and resulting effects of the locking device for sliding windows according to the present invention configured as described above will be described with reference to FIGS. 5 to 7.

First, in order to open the sliding window (door), the locking state is released by pulling and rotating the handle in the opening direction. That is, when the handle axis 300 is rotated in the opening direction through the handle; The rotation cam 450 also rotates in the same direction, and the movable piece 451 pulls the locker 430 downward to release the locking state of the locking jaw 432. {In the embodiment of the present invention, the locking jaw 432 is completely unlocked when the rotation cam 450 along with the handle axis 300 is rotated by about 24 degrees in the door opening direction.} In this state, as shown in FIG. 5, the sliding window (door) is opened by holding the handle and pulling in the opening direction. In addition, the external force of the damper 510 of the damping means 500 is removed, and the operating rod 511 advances due to the elastic force of the restoration spring 540, and the link-type pressing member 520 is rotated in the reverse direction so that the outer end is a damping roller. It protrudes out of the housing 420 together with 530.

On the other hand, if you want to close the sliding window (door), pull the handle in the closing direction; As shown in FIG. 6, before the door frame 200 is slid toward the window frame 100 and the locking jaw 432 of the locker 430 is inserted into the keeper 410, the damping roller of the damping means 500 (530) comes into contact with the central part of the keeper (410) first.

Continuing, as shown in FIG. 7, in the process of sliding the door frame 200 and completely closing the window frame 100, the damping roller 530 rotates the link-type pressing member 520 in the forward direction and moves the housing ( It is pushed into the component installation space 421 of the damper 510, and as a result, the operating rod 511 of the damper 510 moves backward while compressing the restoration spring 540, thereby exerting a damping force. In addition, when the operating rod 511 of the damper 510 is completely retracted and the button member 460 is retracted in contact with the keeper 410, the rocker 430 rises and the locking jaw 432 of the keeper 410 It is inserted into the locking hole 411 and maintained in a locked state.

As such, in the locking device for sliding windows according to the present invention, in the process of closing the sliding window (door), the damping roller 530 and the link-type pressing member 520 are pushed into the component installation space 421 of the housing 420, causing the damper. The operating rod 511 of 510 is moved backward to perform a damping operation. Therefore, impact noise can be reduced when sliding windows (doors) are closed and safety accidents can be prevented.
