Door lock system with push open function}

The present invention relates to a door locking system with a push-open function. More specifically, the locker and the push bar are integrated into the locker housing, improving the compact structure into a single assembly, making it easy to install in a narrow space and improving on-site construction. This is excellent, and structural durability is secured by increasing the size of the rack and finials that transmit the rotational force to the push bar side. In particular, the push bar protrudes after the locker is unlocked in conjunction with the rotational movement of the handle operation axis, preventing malfunction. This is about a door locking system with a push-open function.

Typically, sliding windows such as balcony windows are installed on the window frame so that the window moves in a straight line to open and close the door in a sliding manner. An automatic locking assembly is installed in such a sliding window, and when the window is closed, the locker installed on the window side is placed on the window frame side. It is automatically locked by being locked to the installed striker, and when opening the window, if the window handle is rotated a predetermined angle in the opening direction, the locker is unlocked from the striker on the window frame, allowing the window to be opened.

However, in the case of medium to large sliding windows, the weight of the window increases as thicker glass or double-layer glass is applied compared to before to improve insulation performance, and an airtight means is installed between the window and the window frame to improve the performance of blocking noise and external air inflow. As a result, there was the inconvenience of requiring a lot of force to open the window due to friction caused by contact with the airtight means.

Accordingly, in previously published patent publication No. 10-2021-0010282, a locking device for windows that can selectively perform locking and unlocking operations with a striker provided in a window frame, a plurality of parts are operable inside. Case that can be fixed; An operating gear provided inside the case and including a rotating shaft hole that can be coupled with a handle, an arm pressing portion, and a gear protrusion; a push arm including a pressure receiving portion that interacts with the arm pressure portion and a pressure portion that can separate the window frame or the striker; A slide member that contacts and interlocks with the gear protrusion; And, a technology has previously been proposed that includes a locking member that directly interacts with the striker in conjunction with the slide member, and that allows rotational force applied to the handle to be transmitted to the operating gear and the push arm.

However, the prior art is intended to facilitate the unlocking operation of the locking device by users such as the elderly and the weak with relatively low muscle strength, but the push arm is operated in conjunction with the handle and rotates to apply pressure and cam movement to assist the opening operation. Due to the nature of the cam movement with the arm pressurizing part, a pressure receiving part of a predetermined length must be secured on the push arm to extend the length of the push arm. In addition, this takes up a lot of installation space and the push arm is a system where the push action point is the rotation axis. There was a problem that a lot of force was required for turning as it moved away from the first projection.

Accordingly, the present invention was conceived to solve the above problems. The locker and the push bar are integrated into the locker housing, improving the compact structure into a single assembly, making it easy to install in a narrow space and having excellent on-site constructability. , Structural durability is secured by increasing the size of the rack and finials that transmit rotational force to the push bar side.

The present invention relates to a door locking system with a push-opening function. In this case, the door locking system with a push-opening function has a locker and a push bar integrated into the locker housing, and the structure has been improved to be compact as a single assembly, so that it can be used in a narrow space. In addition to ease of installation, on-site constructability is excellent, and structural durability is secured by increasing the size of the rack and finials that transmit rotational operating force to the push bar side. In particular, it is linked to the rotational movement of the handle operation axis and the push bar is locked after the locker is unlocked. The main components include striker (10), rocker housing (20), rocker (30), rotor (40), straight slider (50), rack (60), and push bar (70) to prevent malfunction by protruding. Do it as

The striker 10 according to the present invention is installed on the window frame 1, and locking grooves 11 are formed on both sides.

The striker 10 is formed with a plurality of through holes so that it can be fixed with screws, and a rocker groove is formed at one or both ends to engage with a rocker 30, which will be described later.

In addition, the locker housing 20 according to the present invention is mounted on the door 2, and has a first compartment 21 in which the striker 10 is accommodated when the door 2 is closed, and is adjacent to the first compartment 21. The second compartment 22 is formed at the position.

The locker housing 20 consists of a main body that accommodates parts described later, and a cover that opens and closes the main body, and is mounted on the door 2 by screwing into fastening pieces formed at one or both ends.

In addition, when the door 2 is closed, the locker housing 20 is formed with first and second compartments 21 and 22 on one side corresponding to the window frame 1, so that the locker 30 and the push bar, which will be described later, are used. (70) are respectively accepted.

In this way, the rocker 30 and the push bar 70 are installed integrally within the single rocker housing 20, thereby improving the compact structure, which has the advantage of improving field constructability.

In addition, the locker 30 according to the present invention is installed in a pair symmetrical to each other in the first compartment 21, is supported by an elastic body 31, and is pressed and supported by the striker 10 when the door 2 is closed. Hooks 33, which rotate in opposite directions around the axis 32, protrude and operate in conjunction with the hooks 33 to engage and restrain the locking groove 11 of the striker 10.

That is, the locker 30 is rotated by the force that closes the door 2, and the striker 10 is locked and bound, and the opening operation is restricted by the straight slider 50, which will be described later.

In addition, the rotor 40 according to the present invention is installed in the rocker housing 20, is coupled to the operation shaft 4 of the handle 3 and rotates, and has a pair of drive cams 42 on the outer peripheral surface that rotate 180°. It is provided equiangularly.

The rotor 40 has a shaft hole penetrating the center of rotation so that the operation shaft 4 of the handle 3 is inserted, and a drive cam 42 is formed at an inclined angle on the outer peripheral surface.

And, during the turning operation, the driving cam 42 performs a cam movement with the driven cam 52 of the linear slider 50, which will be described later, so that the turning operating force of the handle 3 is converted into a linear operating force, thereby causing the linear slider 50 to move in a straight line. It is equipped to do so.

In addition, the linear slider 50 according to the present invention is provided as a pair, and the linear slider 50 is installed in the locking housing 20 and is pressed toward the rotor 40 by the elastic body 51, and has a driven cam at one end. (52) is installed to limit the opening operation of the rocker 30 by the driving cam 42 and cam movement.

The linear slider 50 is installed to enable linear movement within the locking housing 20, and is provided with an elastic body 51 to apply a pressing force toward the rotor 40.

Accordingly, when the turning force applied through the handle 3 is released, the rotor 40 is returned to its original position by the pressing force of the linear slider 50.

At this time, the rocker 30 has a release surface 34 formed to be in contact with the straight slider 50 in a locked operation state to fix the position. And when the linear slider 50 moves toward the rotor 40, it engages with the release surface 34 to limit the opening operation of the rocker 30, and when the linear slider 50 moves straight in the direction away from the rotor 40, the linear slider 50 moves in a straight line away from the rotor 40. The slider 50 is separated from the release surface 34 to allow the locker 30 to be opened.

In addition, the rack 60 according to the present invention is formed in the longitudinal direction on the straight slider 50 installed in the second compartment 22.

The rack 60 is formed on one side of the straight slider 50 exposed to the second compartment 22, and is provided to engage with the pinion 72 of the push bar 70, which will be described later, to maintain the straight line of the straight slider 50. The operating force is converted into a swing operating force of the push bar (70).

In addition, the push bar 70 is installed in the second compartment 22, and engages with the rack 60 to form a pinion 72 at one end to rotate around the support axis 71, and at the other end A push roller 73 is installed to pressurize the window frame 1 when the door 2 is opened.

The push bar 70 has a support hole formed so that one end is inserted into the support shaft 71, and a pinion 72 is provided to be concentric with the support hole.

Here, the support shaft 71 is disposed as far apart from the linear slider 50 as possible within the second compartment 22 to expand the space for forming the pinion 72, thereby increasing the structural durability of the pinion 72. can be reinforced.

At this time, the diameter of the push roller 73 is reduced in size compared to the depth of the second compartment 22, and an idling section is formed between the outer peripheral surface of the push roller 73 and the entrance of the second compartment 22 when the door 10 is closed. (L1) is formed.

Then, the push bar 70 idles within the idling section L1 until the linear slider 50 is moved linearly by the rotor 40 and the rotational movement and the locker 30 is unlocked, and the locker ( After 30) is unlocked, the push roller 73 of the push bar 70 protrudes out of the second compartment 22 and is provided to press the window frame 1.

That is, the rocker 30 is in a locking state, and a release surface 34 is formed to fix the position by interviewing the linear slider 50, and the push bar is formed until the linear slider 50 leaves the area of the release surface 34. The push roller 73 of (70) is provided to idle within the idle section (L1).

Accordingly, when the handle 3 is turned to open the door 2, the straight slider 50 leaves the area of the release surface 34 and the push roller 73 moves out of the second compartment 22. As it protrudes and is provided to press the window frame (1), the opening force by the push roller (73) is achieved without interfering with the locking operation of the locker (30).

In addition, a stop piece 23 is installed inside the second compartment 22 to limit the retraction depth of the push bar 70.

The push roller 73 of the push bar 70 is in contact with the stop piece 23, so that the turning angle of the push bar 70 in the retraction direction is limited.

In this way, the movement distance of the linear slider 50, which is operated in conjunction with the push bar 70 by the pinion 72 and the rack 60, in the direction of the rotor 40 is limited, so that excessive pressing force of the linear slider 50 is reduced. As a result, the turning resistance of the handle (3) is reduced, which has the advantage of allowing anyone to easily open the door without exerting much force.

In addition, a cover rail 74 is provided on the embossed portion 1a of the window frame 1 corresponding to the push roller 73.

The cover rail 74 is formed in a 'U' shape, so that one area is fitted into the embossed portion 1a of the window frame 1, and the other area is integrated into the striker 10 as shown in FIG. 3(a). or is provided to be fixed between the striker 10 and the embossed portion 1a as shown in FIG. 3(b).

Here, the cover rail 74 is formed to be harder than the embossed portion 1a of the window frame 1, and is simply fixed by the striker 10, thereby forming the embossed portion 1a of the window frame 1. As a result, damage to the embossed portion 1a of the window frame 1 due to repetitive frictional load with the push roller 73 is prevented.
