Description

Technical Field [0001] The present invention relates to a self-closing device for sliding window,

More particularly, the present invention relates to an automatic closing device for a door locker window, and more particularly, to a door lock door device capable of automatically closing a window at a predetermined interval during a closing operation of the window mirror, The present invention relates to an automatic closing apparatus for a door lock window using a composite pulley.

Generally, the window serves as a wall for isolating the interior and the exterior, and allows indoor air to be introduced by introducing sunlight and fresh air from the outside.

Such windows include a sliding window, a sliding door window, and a sliding sliding window window, in which a window is lifted up and raised on a rail when the door is opened or closed by using a hardware function of a sliding door window, a door window window or a lift function.

Such a window may cause the user to give more than necessary force due to a mistake or carelessness when closing the window. At this time, the closed window is subjected to a strong impact on the window frame frame by inertia. This may cause noise, and safety accidents may occur if hands are caught in the gap between the window frame frame and the window frame at the moment the window is closed.

In order to prevent this, a safety closing device of a door locker window has been proposed in Korean Patent Laid-Open No. 10-2010-0001776 (published on Jan. 06, 2010).

That is, by installing a damper on a window frame of a conventional door lock window, it is possible to prevent the door lock window from being strongly closed.

However, the sliding door window has a high frictional resistance during opening and closing operations by a mohair or a peeling piece for hermetic sealing, and accordingly, a predetermined force is required for opening and closing the window door at an early stage. Particularly, there is a problem that a large amount of force is required at the last moment of closing the window because of the frictional resistance.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide an automatic closing mechanism for a window, which can automatically close a window at a certain interval during a closing operation of a window by combining a composite pulley module and a spring structure, And to provide an automatic closing device for a door lock window using a composite pulley capable of opening and closing the door.

According to an aspect of the present invention, there is provided an automatic closing apparatus for a hair-dryer window comprising: a main body installed in a window frame; A driving unit having a spring to which one side is fixed in the main body and a composite sheave module which is connected to the other side of the spring and which includes a movable sheave and a fixed sheave interlocked with each other via a wire when opening and closing a window, And a wire fixing part provided on the windowpane so that the wire can be connected to the windowpane. The windowpane is automatically closed at a predetermined interval by elastic restoring force of the spring when the windowpipe is closed, and when the windowpane is opened, So that the window can be opened with a small force.

According to the present invention, it is possible to automatically close the window at a predetermined interval by the resilient restoring force of the spring during the closing operation of the window through the driving unit combining the structure of the spring and the composite pulley module, The tension of the spring through the composite pulley module is advantageous in that the window can be opened easily with less force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the drawings, the same reference numerals as in the drawings denote the same elements in the drawings, unless they are indicated on other drawings.

FIG. 1 is an elevation view of an indoor side of a door lock window provided with an automatic closing device for a door lock window using a composite sheave according to the present invention, and FIG. 2 is a detailed view of the 'A' portion of FIG.

1 and 2, an automatic closure apparatus 1 for a door lock window using a composite sheave according to a preferred embodiment of the present invention includes a body 100, a driving unit 200, a wire fixing unit 300 ).

The configuration of the present invention will be described in detail as follows.

The main body 100 constitutes the main body of the automatic closing device 1 and is provided on the window frame 10. Specifically, the main body 100 is installed on one side of the top of the window frame 10 in which the window 20, which is slidably opened and closed, is closed. In the main body 100, a storage space is provided so that a plurality of components constituting the driving unit 200 can be installed.

Referring to FIG. 3, a guide rail 110 is formed inside the main body 100 along the opening / closing direction of the window 20. The detailed structure of the composite pulley module 220 including the guide rails 110 will be described with reference to a driving unit 200 to be described later. .

The driving unit 200 is installed in the receiving space of the main body 100 and operates so that the window 20 can be automatically closed by the elastic restoring force of the spring 210 during a certain period of time when the window 20 is closed It plays a role.

4, the driving unit 200 includes a spring 210 having one side fixed to the main body 100, a spring 210 connected to the other side of the spring 210, and a wire (not shown) And a composite pulley module 220 in which a moving pulley 222 and a fixed pulley 223 are interlocked with each other via a pair of pulleys 220 and 225.

In this case, the spring 210 is installed on one side of the main body 100, which is the direction in which the window 20 is closed, and the composite pulley module 220 is installed on the other side of the main body 100, do.

That is, the spring 210 allows the window 20 to be closed automatically at a predetermined interval by the elastic restoring force when the window 20 is closed, and the composite pulley module 220 allows the window 20 to be closed with a small force So that the window 20 can be opened easily.

The composite pulley module 220 includes a moving member 221 connected to the other side of the spring 210 and reciprocally coupled to the guide rail 110 in the main body 100 through a roller 221a, One or more movable pulleys 222 installed on the movable member 221 to be reciprocally moved integrally with one another and one or more fixed pulleys 222 installed on the other side of the main body 100 and connected to the moving pulley through a wire 225 223).

In this case, the spring 210 always pulls the movable member 221 in the direction in which the window 20 is closed so as to maintain the tension of the wire 225 wound on the movable pulley 222 and the fixed pulley 223 have.

For reference, a composite pulley is a device that changes the direction of force or exerts a large force with less force. It has a fixed pulley and a moving pulley. When using a fixed pulley, there is no gain of force but only the direction of the force is changed, but the movement pulley sees the benefit of the force.

That is, to lift an object using a moving pulley, a force of half the weight of the object is required. However, the amount of work done is the same as using a moving pulley because you have to pull twice as much as when you do not use a moving pulley. In other words, if you use tools like pulleys, you can see gains in power, but there is no benefit in work.

For example, in the case of two fixed pulleys 223 and two movable pulleys 222, the pulling force of the wire 225 is reduced by a factor of four, and the moving distance of the end of the pulling wire 225 is increased by four times.

As another example, when three fixed pulleys 223 and two movable pulleys 222 are used, the pulling force of the wire 225 is reduced by a factor of six and the moving distance of the pulling wire 225 is increased six times.

In the present invention, an example of a case where two fixed pulleys 223 and two movable pulleys 222 are provided will be described. The number of the fixed pulleys 223 and the number of the moving pulleys 222 can be changed according to the size and weight of the window 20.

2, the wire fixing part 300 is installed on one side of the upper side of the window 20 slidingly openably coupled to the window frame 10 to pull the wire 225 wound on the composite pulley module 220 The wire fixing part 300 may be formed of various structures such as a ring or a fixing pin that can fix the end of the wire 225 to the window 20.

The wire 225 is sequentially wound on the fixed sheave 223 and the moving sheave 222 while one end 225a of the wire 225 is fixed to the moving member 221. Finally, The other end 225b of the wire 225 is fixed to the wire fixing portion 300 after the movable sheave 222 is wrapped.

The wire fixing unit 300 is installed at a position corresponding to the main body 100 provided with the driving unit 200 and operates the driving unit 200 in conjunction with the opening and closing operations of the window 20.

In this case, the wire 225 pulled by the wire fixing part 300 is formed to have a length corresponding to the width at which the window 20 is opened.

The wire fixing part 300 is pressed against one side of the protruding part 221b of the moving member 221 at a predetermined point during the closing operation of the window 20 and is pressed against the side surface of the wire fixing part 300 by the resilient restoring force of the spring 210, And an activator 310 for automatically closing the window when the window 221 is moved.

In addition, the main body 100 is operated together with the spring 210 by the movement of the movable sheave 222 interlocked with the operation of closing the window 20, thereby canceling the elastic restoring force of the spring 210, And a damper unit 400 for controlling the automatic closing speed of the damper unit 400.

The damper unit 400 includes a damper cylinder 410 fixed to one side of the main body 100 and a damper cylinder 410 coupled to the damper cylinder 410 to be movable forward and backward along the opening direction of the windowpane 20 And a damper rod 420 whose tip is fixed to the movable member 221. [

Hereinafter, the operation principle of the automatic closure apparatus 1 for a shutter window system using the composite pulley according to the present invention having the above-described structure will be described.

6, the wire 225 fixed to the wire fixing portion 300 is pulled when the window 20 is opened, and the wire 225 is pulled to move the moving member 221 are tensioned. In this case, the spring 210 can be pulled easily by a small force as it is pulled by the composite pulley module 220. For example, when the spring 210 is pulled by a large amount of 50 mm, the window 20 to which the other end of the wire 225 is connected is opened by about 200 mm.

When the opening and closing force required for opening and closing the window 20 is 4 kgf, the force of the spring 210 is required to be 4 kgf. That is, the force required to open the window is 8 kgf (window opening / closing force 4 kgf + spring 4 kgf). The force for pulling the spring 210 is reduced to 1/4 due to the use of the composite pulley module 220 in which two moving pulleys 222 and two fixed pulleys 223 are applied, The force required for opening is 5kgf (4kgf of window opening / closing force + 1kgf of spring).

7, the wire 225 drawn by the wire fixing portion 300 is released in the opposite direction due to the elastic restoring force of the spring 210. At the same time, (221) is moved in the closing direction of the windowpane (20).

When the opening interval of the window 20 is approximately 50 mm, the activator 310 provided on the window 20 is pressed against one of the projections 221b of the movable member 221 and the elasticity of the spring 210 The movable member 221 moves together with the restoring force to close the window 20 (state of FIG. 2). That is, at this moment, the automatic closing of the window 20 is possible only by the elastic restoring force of the spring 210 without applying any external force to the window 20.

In this case, when the damper unit 400 is provided in the main body 100 (see FIG. 5), the movable pulley 222 is moved together with the spring 210 when the window 20 is closed, The automatic closing speed of the window shade 20 can be controlled by canceling the elastic restoring force of the window shade 210, thereby preventing the window shade 20 from being strongly closed.

As described above, the automatic closing device 1 for a door lock window using the composite sheave according to the present invention is configured such that the closing operation of the window shade 20 is performed through the driving part 200 combining the structure of the spring 210 and the composite pulley module 220 It is possible to automatically close the window 20 at a predetermined interval by the elastic restoring force of the spring 210 and by pulling the spring 210 through the composite pulley module 220 when the window 20 is opened, It is possible to easily open the window 20 by force.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.

Particularly, in the present invention, the automatic closing device 1 is shown on the upper side of the window, for example. However, the present invention is not limited to this and can be formed on the lower side of the window. However, when there is a concern that a safety accident due to carelessness may occur when the automatic closing device 1 is installed at the lower part of the window, the automatic closing device 1 is installed on the upper part of the window where the user's hands or feet do not touch .
