Description

{APPARATUS FOR LOCKING WINDOWS AND DOORS}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a window locking device, and more particularly, to a window locking device that easily opens and closes a window, a door, and a sliding door by applying a force in a window opening direction.

Generally, windows are collectively referred to as windows and doors.

A window is an opening which is not used for entering or exiting a person on a wall or a ceiling. It is used for the purpose of sight, ventilation, and mining, and the door is used for the entrance and exit of a person or object.

The material of the window is made of aluminum, synthetic resin, plastic, glass, steel, stainless steel, bronze, wood, refractory material.

In particular, windows have functions such as airtightness, watertightness, resistance to wind pressure, heat insulation and sound insulation. The airtightness of a window indicates the amount of air that flows into the room due to external pressure. It is closely related to the sound insulation as well as the heat insulation. The watertightness penetrates into the interior due to rain, wind, heavy rain and wind pressure And wind pressure resistance or external wind resistance means the degree to which window and glass can withstand wind or pressure and heat insulation refers to the degree to which heat inside is lost due to inherent heat conduction depending on the material. The window includes a fixed frame fixed to the wall, such as a window frame, and a movable frame corresponding to a window frame that is openably and closably coupled to the fixed frame. The soundproofness of the window means the degree of hermeticity of the contact between the fixed frame and the moving frame, and the degree of blocking the external noise according to the profile design.

In addition, the formation of condensation is less, and the development of window technology is being carried out in order to improve heat resistance, opening and closing flexibility, weatherability and maintenance performance. Here, the opening / closing flexibility means that the operation of opening the locking state is smoothly performed with the minimum force or the operation of opening the window in a locked state with the operation of closing the window is automatically performed . ≪ / RTI >

In the automatic locking device for a window according to Patent Document 1 or Patent Document 2 which is the background of the invention, since the rotation axis of the handle is arranged in a direction perpendicular to the front face of the window, a force is applied to the user to twist the wrist At the same time, the user must perform the operation of opening the window linearly by giving more force to the arm, so that the window can not be opened relatively easily or the force This is a very uncomfortable and difficult disadvantage for the elderly or children.

In the automatic locking device of the prior art such as Patent Document 1 or Patent Document 2, the latching grooves are formed at both ends in the longitudinal direction of the striker, and the hook of the main body directly collides with the edge of the latching groove, The impact force at the time of closing the window is directly transmitted to the hook, so that the operating performance quality of the automatic locking device is lowered, such as an increase in the durability of the hook and the increase in shock noise between the hook and the striker .

In the conventional automatic locking device, since the hook is retracted by the elastic force at the time of opening the window, when the window is closed again, the hook again strikes the edge of the latching groove of the striker so that a scratch And as a result, the fastening force is loosened, and the gap or clearance between the window frame and the window frame is increased, so that the sealing performance of the window is deteriorating.

In addition, since the automatic locking device of the related art is composed of three components including a handle, a locking device, and a striker, there is a disadvantage that the assembling property is relatively lowered and the operating noise is relatively large.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

In addition, the window of the present invention is generally referred to as a window or a door. In the following description of the embodiments, the window is only described or referred to based on a window, and any window or door can be included in the present invention in the case of a hinged door opening and closing structure.

1 is a profile cross-sectional view of a window frame and a window frame to which the window locking device of the present invention is applied.

Referring to FIG. 1, the present embodiment is largely composed of a handle assembly and a striker 30, which provides a simple, smooth, and quick window opening / closing function as compared to the prior art.

The window includes a movable frame 10 corresponding to a window frame surrounding an outer periphery of a plate material such as glass or plastic and a fixed frame 20 such as a window frame fixed to the wall of the building.

The stationary frame 20 includes a rail 21 and a striker 30 is coupled to an inner vertical protrusion 22 which faces the movable frame 10 from the stationary frame 20. Here, the striker 30 is coupled using a plurality of fixing screws.

In this case, the lever 100 and the shaft body 300 are rotated with respect to the hinge block 380 as the principle of the leverage. As a result, the fingering 370 of the shaft body 300 rotates the lock hook 400 Lift up to make a state as shown in Figure 11.

11, the hook shaft portion 410 of the lock hook 400 exits the square hole 31 of the striker 30 and is moved to the top dead center position again due to the lock hook 400 lifted as described above, As a result, the hollow guide portion 610 is returned to the inside of the hollow guide portion 610 and released.

Referring to FIG. 12, the lock hook 400 is in the top dead center position, and the lock button 500 does not interfere with the forward movement. Accordingly, the lock button 500 receives the elastic force of the button spring 530 and moves forward in its original state.

The locking button 500 advances back to the state as shown in FIG. 5 or FIG. 7, and the locking hook 520 of the locking button 500 supports the locking hook 400 again. The lever 100 and the shaft body 300 are then returned to the state shown in FIG. 5 or 7 by receiving the elastic force of the shaft spring 350 when the user removes the turning force applied to the lever 100 , The window is also released.

That is, in the existing product, there is a disadvantage in that noise is generated, abrasion, or scratch occurs due to the structure in which the hook strikes the striker, but the present embodiment has a structure in which the lock hook 400 protrudes toward the square hole of the striker The disadvantages of the existing products can be improved.
