Description

{WINDOW LOCKING UNIT FOR WINDOWS AND DOORS}

More particularly, the present invention relates to a window locking device for a window, and more particularly, because it is structurally simple and easy to manufacture and assemble, and since the camshaft and the moving coaxial shaft are realized, space can be saved and volume can be reduced. And an improved window locking device for a window that can be easily, quickly, accurately and reliably locked at a time.

Generally, a window is a collective term for a window and a door. The window is mainly used for mining, ventilation, and the like, and the door is used for the purpose of entering or leaving a person or an object.

Since such a window functions as a wall separating the outside and the inside, it is natural that the airtightness, the heat insulation, the watertightness, the soundproofing, and the windproofness should be high.

Herein, the definition of a term is that an outer frame constituting a window, that is, a window frame is referred to as a window frame, and a portion having a glass for sealing a window frame that is inserted into the window frame is called a window pad.

In addition, a sliding window window having a sliding window among the windows has a rail formed on an upper portion of a window sill and a window sill lower portion for sliding a window, and a roller capable of moving while rolling over the rail is provided on a window.

As described above, most of the disclosed windows have a rectangular shape, and the opening and closing methods thereof are mainly composed of a structure that uses a roller to slide.

Meanwhile, the window constituting the window has a locking function in order to prevent the intrusion of the outside, which is provided with a striker in a part of the window, and a locker is provided in the window frame so that the striker is hooked to the locker, So that it can not be opened from the outside.

Representative prior art related to such locking devices are disclosed in Korean Patent No. 0427845 (2006.09.25), Registration No. 0446666 (2009.11.11), Registration No. 1172418 (2012.08.02), Open Patent No. 2011-0073809 (June 30, 2011).

However, in the case of the above-mentioned Registration No. 0427845, although the structure is simple and effective, since the hook-shaped locking jaw interacts with the cam to perform the locking and unlocking while linearly moving in the vertical direction, There is a concern that the sliding guide is separately provided, and since the sliding space needs to be separately secured, there is a disadvantage that the volume increases.

That is, since the window lock device should be fixed to one side of the window, the volume should not be large.

In addition, in the case of the registration room No. 0446666, there is provided a locking structure of a pivoting type so that an operation error is less than that of a sliding type, but an additional member having a locking protrusion is separately provided for power transmission of the cam, Therefore, there is a disadvantage that the power transmission process is complicated and accordingly the operator's power is large, and the assembling structure is complicated and the manufacturing cost is increased. In this case as well, So that the volume of the locking device is increased.

In addition, in the case of the above-mentioned Japanese Patent No. 1172418, although a stable and accurate locking function is performed, the structure is too complicated to increase the manufacturing cost, and in addition, , But this is not an efficient structure because the volume is limited.

In addition, although the above-mentioned Patent Publication No. 2011-0073809 has advantages in that it is easy to operate, the operation is unnatural and requires a lot of effort due to the pressing method. Especially, when the rocked window is lifted up or pulled, There is a fear that the lock function is released, and thus it is vulnerable to crime prevention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

Before a detailed description of the present invention, it is assumed that the locking device according to the present invention excludes a locked object provided on a window frame, that is, a locking object that is locked to the locked object.

1 to 4, the window locking device for a window according to the present invention includes a fixing plate 100.

The fixing plate 100 is a narrow plate, and is fixed to a windowpane.

For this, a plurality of screw holes 110 are formed at both ends of the fixing plate 100, and a fixing screw (not shown) is screwed to the window frame, that is, It is firmly fixed on this window.

The housing 200 is integrally formed with the fixing plate 100. The housing 200 has a space therein and one side is opened and a cover 210 is assembled in the opened portion. The cover 210 is detachably fixed through a known fixing member such as a bolt or a screw.

A housing through hole 220 is formed at the center of the inner bottom surface of the housing 200.

At this time, the housing through-hole 220 is formed to penetrate through the housing 200 so that a lever (not shown) is fitted in like a cover through hole 212 formed in the cover 210, It can be operated only by inserting the lever regardless of the installation position on the right side, so it is possible to use the left side lock device and the right side side lock device as a conventional device, thus making it very efficient.

In addition, a pair of guide pins 230 protrude from both sides of the housing through-hole 220 so as to be symmetrical in the radial direction of the housing through-hole 220.

The first spring SP may be a tension spring, and the second spring 570 may be a compression spring.

In addition, an arc-shaped guide 240 having a predetermined curvature in the depth direction of the housing 200 is formed in front of the housing through-hole 220, and partition walls 250 And the slide groove 260 is formed.

Further, a pair of rotation bosses 270 protrude from the outer sides of the pair of guide pins 230 with an interval therebetween.

A stopper 280 is formed below the rotary bosses 270 with an interval therebetween. One surface of the stopper 280, more specifically, a surface facing the housing through-hole 220, And the opposite surface forms a vertical plane.

A floater 300 is inserted into the guide pin 240. The floater 300 is a cylindrical member having protrusions 310 projecting symmetrically on both sides of the outer circumference of the floater 300, Is formed with a fitting hole 240 to be fitted in the guide pin 240 and is assembled by the first spring SP so as to be always pushed forward.

Since the clamp piece 500 of the floater 300 maintains a state of being always in contact with the upper jaw 520 described below unless an external force is applied thereto, It is not locked and is waiting for unlocking.

A pair of slide pieces 330 that slide along the slide groove 260 protrude below the outer circumferential surface of the floater 300 while being inserted into the slide groove 260.

In addition, an outer circumferential surface of the floater 300 below the outer circumferential surface, more precisely between the pair of slide pieces 330, is seated on the arcuate guide 240.

More specifically, the floater 300 is formed to have a thickness smaller than the length of the arcuate guide 240 and to be movable within the length of the arcuate guide 240.

A cam groove 340 is formed on the inner circumferential surface of the floater 300. The tip of the floater 300 contacts the rim of the housing through hole 220 and is not discharged out of the housing through hole 220. [ Topped.

Also, the actuator 300 is fitted with the actuator 400.

The actuator 400 has a cam protrusion 410 formed on the outer circumferential surface of the cam protrusion 410 and has a predetermined shape so as to be fitted to the cam groove 340 formed on the inner circumferential surface of the floater 300 when the actuator 300 is fitted in the floater 300. do.

Here, the cam groove 340 has a curve shape in which the actuator 400 and the floater 300 can maintain a fixed state without moving relative to each other when the lever is completely turned in the locking direction, and conversely, The same must be true when turned completely.

In addition, a lever insertion hole 420 is formed in the actuator 400 in the longitudinal direction. The lever insertion hole 420 is formed by assembling a lever (not shown) to rotate the actuator 400 And has a polygonal shape, most preferably a rectangular shape, except for a circular shape.

A hook 430 protrudes around one end of the actuator 400 so that the actuator 400 can be caught without passing through the floater 300. The length of the actuator 400 is longer than the length of the arc- As shown in FIG.

When the actuator 400 rotates, the cam protrusion 410 and the groove 340 are engaged with each other and are twisted with each other, so that the floater 300 moves forward and backward. However, This is because the only member that can move in the assembled state is the floater 300 only.

As described above, according to the present invention, since the floater 300 positioned coaxially with the actuator 400 is structured to lock and unlock while moving back and forth, a separate space is not required for providing a structure for pivoting for a locking function Optimal design is possible and volume can be reduced.

In addition, a pawl 500 is fitted to the rotary boss 270, respectively.

At this time, a jaw 272 is formed in the rotation boss 270 to form a space through which the floater 300 can flow, and the jaw 272 is longer than the length of the floater 300 It is preferable to have a height.

Since the floater 300 can flow within the range of the height of the jaw 272, the catching piece 310 of the floater 300 can be caught or released by the catch 500 have.

For this purpose, the catch 500 includes a substantially 'A' shaped catch portion 510 which can be caught by a catch (not shown) fixed to the window frame, A lower jaw 530 formed at a lower circumferential portion of the upper jaw 520 at an interval from the upper jaw 520 and a spring protrusion 550 protruding rearward adjacent to the lower jaw 530, (540).

A spring fixing boss 560 protrudes from the upper side of both ends of the housing 200 and a second spring 570 is provided between the spring fixing boss 560 and the spring protrusion 550.

At this time, the upper jaw 520 is sloped and disposed so as to be in contact with the upper surface of the fitting piece 310 of the floater 300.

When the lever inserted in the lever fitting hole 420 is turned in the opening direction by the user, the floater 300 is pushed up toward the cover 210 by the interaction between the cam groove 340 and the cam protrusion 410 During this process, the fitting piece 310 pushes up the upper jaw 520 while digging the lower portion of the upper jaw 520.

Accordingly, the pawl 500 is rotated about the pivotal boss 270 so that the two pawls 500 are opened to each other. This state is an 'OPEN' state for opening the window.

In particular, since the second spring 570 always pulls the support piece 540, the pawl 500 maintains a state in which it always tries to rotate in the direction of pawl. However, as described above, It is kept open, that is, the open state, and this state can be regarded as a state in which the lever is turned in the opening direction.

In contrast, when the lever is rotated in the locking direction, the fluidifier 300 is pushed downward in the direction opposite to the cover 210, i.e., in the depth direction of the housing 200, so that the engagement state between the fitting piece 310 and the upper jaw 520 And at the same time, the two pawls 500 are rotated by the action of the second spring 570 so that the pawls 500 of the pawl 500 are locked and locked to the pawl that is naturally fixed to the window frame .

Thus, the window lock according to the present invention does not require a separate space for pivoting the pawl 500, and the pivotal actuator 300 coaxial with the actuator 400 rotated by the lever is actuated Since the locking and unlocking are performed while moving in the axial direction of the magnet 400, the space can be efficiently used and the size of the locking device can be minimized.

Moreover, since the structure in which the rotational motion and the linear reciprocating motion are performed in parallel is possible, smooth operation can be performed without applying a large force, and a more accurate locking function can be performed.
