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.

The lock hook is held at the top dead center position so as to be in contact with the striker before closing the window or when the window is opened so that the frictional force It is possible to provide a window locking device capable of relatively increasing the window opening / closing force and reducing the noise during opening / closing.
In other words, in the process of moving the movable frame toward the striker of the fixed frame, only one lock button supported by the button spring comes in contact with the button groove of the striker, so that the impact force due to such contact can be absorbed by the button spring And the locking hook can be automatically engaged as well as the lock hook interlocked with the lock button is inserted into the square hole of the striker.
In addition, according to the present invention, since the lock hook is seated in each square hole of the striker by the lock button, the lock hook does not hit the striker directly, so that no impact noise due to contact between the lock hook and the striker is generated, The impact force is not directly transmitted to the lock hook, so that failure of the lock hook can be prevented in advance, thereby increasing the durability of the window lock apparatus relatively and increasing the service life of the window lock apparatus.
In the present invention, since the lock hook only serves as a latching jaw against the square hole of the striker, compared with the conventional technique in which the lock hook directly bumps against the rim of the square hole of the striker after a long period of use, Or deformation can be prevented in advance.
Further, even if the long-time window locking device is used, there is no deformation or the like, so no clearance is generated between the lock hook and the rim of the square hole of the striker, thereby preventing deterioration of the sealing performance of the window.
Since the operating direction of the lever operating force and the moving direction of the moving frame are on the same operating surface, the user can easily operate the lever to open the window easily with a relatively small force .
Further, since the lever rotation direction of the present invention coincides with the movement direction of the movement frame and the rotation radius of the lever is shorter than that of the automatic locking device having a general rotary knob, the lever operation is easy and the opening of the window is simple and quick There are advantages to be able to.
In addition, the present invention can be constituted of two major components, such as a handle assembly and a striker, to provide a simple and smooth window opening / closing function.

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.
Further, the frame 10 is coupled to the stationary frame 20 so as to be movable along the rail 21.
The fixed frame 20 includes a pair of inner window doors and a pair of outer window doors which are coupled to the fixed frame 20 so as to be movable along the other rails and spaced apart in the thickness direction of the fixed frame 20.
At this time, the present invention has a lever 100 and a housing 200, which can be coupled to either a window pane or an outer window pane, and are made thin enough to prevent interference against a door located on the opposite side of the combined position.
The present invention includes means for maintaining the lock state with respect to the striker (30), or converting the locked state to the released state through the rotation (R) of the lever (100). For example, the lever 100 and the components interlocking with the lever 100 may correspond to the means.
Since the direction of the rotation of the lever 100 in this embodiment coincides with the direction of movement M of the moving frame 10 and the rotation radius of the lever 100 is relatively short as compared with that of the conventional rotary knob, The operation of the lever 100 is easy and the opening of the moving frame 10 can be made simple and quick.
For example, since the direction of rotation (R) of the lever 100, which is the direction of operation force of the lever 100, and the direction of movement (M) of the movement frame 10 lie on the same acting surface, The movable frame 10 can be smoothly and easily opened without using an excessive force to operate the lever 100. [
Particularly, when the window frame 10 is opened (e.g., released) before the window frame 10 is moved toward the striker 30, i.e., before the window is closed or locked, the lock hook 400 is moved to the striker 30 When the movable frame 10 of the window is moved toward the fixed frame 20, the lock hook 400 is brought into contact with the bottom dead center position (e.g., the inner side of the handle assembly) Since the lock hook 400 is inserted into the square hole 31 of the striker 30 by projecting to a position (e.g., the outside of the handle assembly), a smooth locking operation can be performed.
The lock hook 400 is inserted into the square hole 31 of the striker 30 to form a shoulder so that the movable frame 10 is kept in a locked state so as not to move along the rail 21 of the fixed frame 20. [ .
The release state means that the lock hook 400 is detached from the rectangular hole 31 of the striker 30 and returns to the original top dead center position due to the rotation R of the lever 100, 21). ≪ / RTI >
Accordingly, the movable frame 10 can be smoothly moved along the rails 21 of the fixed frame 20. Fig.
The configuration and the coupling relationship of the present embodiment for implementing the above-mentioned locked state or released state will be described with reference to an exploded perspective view.

5, when the window 100 is opened, that is, in the state of lifting up the elevation between the fixed frame 20 and the movable frame 10, the lever 100 is moved in the vertical direction I.e., in the Y-axis direction.
At this time, the button shaft portion 510 of the lock button is exposed on the movement line of the movable frame 10, and when the movable frame 10 moves toward the striker 30 for the locked state, It can be contacted.
In addition, in the housing 200, the lock hook is raised by the lock button.
That is, in the housing 200, the hook portion of the lock button supports the hook connection portion of the lock hook. Thus, the hook shaft portion of the lock hook is located inside the hollow guide portion 610 of the bottom plate, and even if the lock shaft is moved toward the striker 30, With no interference.
Accordingly, the user can smoothly move the movable frame 10 toward the fixed frame 20 to make a state as shown in FIG. 6 in order to make a locked state.
6, the button shaft portion 510 of the lock button 500 is in contact with the side surface of the button groove 32 of the striker 30, in accordance with the movement of the movable frame 10.
7, when the button shaft portion 510 of the lock button 500 and the engaging jaw 520 contact the button groove 32 of the striker 30 due to the contact and the movement of the moving frame It moves backward as if it is millimeter.
As the lock button 500 is pulled back, the released lock hook 400 is moved downward by the elastic force of the hook spring.
At this time, the latching jaw 520 is also retracted, and the lock hook 400 can not be supported.
The hook shaft portion 410 of the lock hook 400 is moved to the bottom dead center position as it is inserted into the square hole 31 of the striker 30 and the state shown in Figs. 5 to 9, since the lever 100 does not move at all, the lever 100 maintains a locked state in which the operating noise of the lever 100 is not generated. In this locked state, the fingering 370 of the shaft body 300 is placed under the bottom of the hook connection part 420 of the lock hook 400.
Thereafter, the user can change the locked state to the released state as described below.
Referring to FIG. 10, the user rotates (R) the lever 100 in such a manner that the lever 100 is urged in the direction of movement (M) of the window locking device to open the window.
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.
