Description
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.

According to an aspect of the present invention, there is provided a window locking device installed in a moving frame movably coupled to a rail of a fixed frame having a striker, wherein the window locking device is fixed to the moving frame, A bottom plate having a pair of hollow guide portions and a hollow support portion between the hollow guide portions; A lock button coupled to the bottom plate to move in a moving direction of the moving frame; A lock hook coupled to the bottom plate to move in a direction perpendicular to a moving direction of the moving frame; A shaft body rotatably disposed by a hinge block coupled to a block mounting projection of the bottom plate to lift the lock hook; A housing coupled to an upper portion of the bottom plate and having a pair of lever pivot holes; And a lever coupled to the end of the shaft vertical axis of the shaft body projected through the lever pivot hole by a lever bolt.
The lever includes a pair of lever corner portions spaced apart from each other so as to coincide with ends of the vertical shaft of the shaft and formed with lever bolt holes for insertion of the lever bolts, A lever body having a lever hollow shaft portion into which the shaft vertical axis of the shaft body is inserted and a lever plate connecting the corner portions with each other; And a lever body cover coupled to the lever body to enclose the lever plate and the lever corner portion.
The housing further includes: a housing lower portion which is opened toward the bottom plate and is engaged with each other while forming a step corresponding to the outer shape of the bottom plate; A housing side wall extending along the lower portion of the housing, the housing side wall defining a space for accommodating the lock button, the lock hook, and the shaft body; A first upper surface portion which is connected to the upper portion of the housing side wall to close the upper portion of the housing, the first upper surface portion being recessed to receive a user's finger and eccentrically disposed toward a side wall of the housing; A second upper surface portion protruding relatively to the one upper surface portion and having the lever pivot hole formed therein; And a cap formed on the one upper surface portion and on which the screw cap is seated.
The bottom plate may further include: a spring supporting protrusion protruded toward the opposite side of the hollow supporting portion; And the block mounting protrusions protruded on both sides of the spring support protrusion.
The lock button may include a button shaft portion inserted into the hollow support portion and having a lower end projecting outwardly of the hollow support portion; A hooking step of a Hangul type cross-sectional shape formed at an upper end of the button shaft portion; And a button spring coupled between the latching jaw and the spring support protrusion.
The lock hook may include a hook shaft portion inserted into the hollow guide portion and having a spring hole for hooking the spring, A hook connecting portion connecting the hook shaft portions and having a hooking groove portion for receiving the hooking jaw portion; And a hook spring inserted into the spring hole of the hook shaft portion, respectively.
The shaft body may include: a shaft horizontal axis rotatably coupled to a hinge block of the block mounting projection of the bottom plate; Shaft connecting portions integrally formed at both ends of the shaft horizontal axis; A shaft vertical shaft projecting integrally on an upper surface of the shaft connecting portion and having a bolt fastening hole for fastening a threaded portion of the lever bolt; A lever portion horizontally protruding from an intermediate position of the shaft horizontal axis; A spring insertion protrusion protruding from a center of an upper surface of the lever portion and fastened with a shaft spring; A finging protruding from the leverage portion to both sides of the spring insertion protrusion to the finger seating groove of the bottom of the hook connection portion, respectively; And a hinge block coupled to the block mounting protrusions respectively with block fixing screws for rotatably supporting the shaft horizontal axis.
The striker may further include: a body attached to an inner vertical projection of the fixing frame; A pair of rectangular holes formed in the front surface of the main body perpendicular to the movement direction of the moving frame and fastened to the hook shaft portion of the lock hook, respectively; And a button groove formed in a side corner of the body between the rectangular holes.
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.
