SAFETY WINDOW CLOSER OF WINDOWS

The present invention relates to a safety closing device for windows and doors, and more particularly, to include a shock absorbing means in a window that is opened in the form of a slide to absorb a shock hit the window frame when the window is closed to prevent breakage as well as safety accidents. A safety closing device for windows and doors has been improved.

In general, windows and doors are generic terms of windows and doors, and windows are mainly used for the purpose of lighting, ventilation, and the like, and doors are used for the entrance of a person or an object.

Since the windows serve as a wall partitioning the exterior and the interior, it is natural that airtightness, heat insulation, watertightness, sound insulation, and wind pressure resistance should be high.

In the sliding window having a sliding window among the windows, rails are formed on the upper frame and the lower window frame, respectively, for sliding of the window frame, and rollers are formed on the upper and lower surfaces of the window to move in rolling contact with the rail. Has a structure.

In such a window, when the window sill is applied to close the door or window, the window sill is closed by impacting the window frame by inertia, which not only generates noise, but also damages or damages when an object is placed between the window frame and the window sill. You could get your back injured.

In order to prevent this, in case of opening windows such as the front door of an apartment door, a folding damper is installed at the hinge portion to alleviate the impact when the windows are closed.

However, in the case of the sliding window, unlike the casement window, because it operates over a large area along the transverse direction of the window frame it was not possible to use a folding damper.

Accordingly, the damper means (buffer means) improved to fit the sliding window has been applied for a number of names such as 'safe window', 'safe closing device', and the present applicant has also applied for a number of related technologies.

As an example, it has disclosed the Patent Publication No. 2010-0001776 as shown in Figs.

According to the disclosed, the safe closing device of the secretary window to the window is slidably installed on the rail of the rectangular frame (1), the body (11) fixedly installed on the frame (1); A carrier 20 slidably installed along the sliding direction of the window in the body 11; A spring (30) having one end fixed to the frame (1) and the other end fixed to the carrier (20) to apply an elastic force to the carrier (20) in the closing direction of the window; A damper (40) installed in the body (11), the piston (41) coupled to the carrier (20) to provide a buffer against the elastic force of the spring (30); A locking member 50 coupled to the window; According to the position of the locking member 50 according to the sliding operation of the window, the locking state and the carrier to maintain the carrier 20 in a predetermined position in the state that the elastic force of the spring 30 is applied to the carrier 20 It can be seen that the safety closing device provided with; locking / releasing means for switching to the unlocking state 20 is moved with the locking member (50).

At this time, reference numerals '10a' and '51' in the drawings are brackets, and '21' is a cam member.

By the way, the safety closing device completed by the applicant of such a structure has been found to have a remarkably advanced function and effect compared to the existing, but despite such advantages, the user to force the force to beat the elastic force that the spring 30 has There is a disadvantage that can be opened only when the window (2) has been applied, too much force due to the opening of the window (2) has caused a lot of inconvenience in use.

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

As shown in Figures 3 and 4, the safe closing device of the window according to the present invention is composed of a window frame fixing bracket 100 is fixed to the window frame which is a frame, a window pair fixing bracket 200 is fixed to the window frame is a door .

In addition, the guide plate 210 is coupled to one side of the window fixing bracket 200 so that the guide plate 210 is guided in a straight line along the window frame fixing bracket 100 so that the window fixing bracket 200 is window-shaped. Along with the window frame fixing bracket 100 is configured to be guided along the window frame fixing bracket (100).

At this time, as shown in Figure 4, the window frame fixing bracket 100 is composed of two plate members (110a, 110b) separated from each other in a moldable manner.

In addition, the first guide groove 112 and the first guide groove 112 formed in a 'U' shape on one side of the inner surface of the plate member (110a, 110b) is formed at intervals, one end is flat and the other end is The second guide groove 114 having an upward curved shape is formed.

In addition, a portion of the inner surface of the plate member (110a, 110b), preferably in the space between the first and second guide grooves (112, 114) damper 120, which is a kind of cylinder as shown in Figure 5 is installed, The damper rod 122 is connected to the damper 120.

In addition, hinges 134 and 144 coupled to the first guide groove 112 and the second guide groove 114, respectively, are positioned between the plate members 110a and 110b, respectively, along the first and second guide grooves 112 and 114. The first and second cams 130 and 140 which are sliding guides are provided.

The first and second cams 130 and 140 are connected to each other by a spring 150.

In particular, the first locking portion 132 having a substantially '?' Shape provided at the lower end of the first cam 130 is always configured to rotate in one direction, that is, in a direction facing each other, and the second cam. The second catching part 142 similar to the first catching part 132 is provided at the lower end of the 140, but the second catching part 142 is not rotated but formed of a fixed type that does not flow.

Meanwhile, first and second installation grooves 220 and 230 are recessed at an appropriate distance on one side of the window fixing frame 200, and first and second operation holes are respectively formed in the first and second installation grooves 220 and 230, respectively. 240 and 250 are installed, and the first and second actuating holes 240 and 250 are respectively rotatably installed in one direction, that is, opposite directions facing each other by the torsion spring 260 and the first cam. Disposed to be caught or interfere with 130.

In this case, the force for returning the first and second operating ports 240 and 250 may not be used as the torsion spring 260, but it may be configured to always stand upright even if it falls down by adjusting the center of gravity like the looting machine.

In addition, a locking protrusion 270 is formed on the upper surface of the window fixing frame 200 which is separated from the second operation tool 250 by the length of the spring 150 when it is not extended.

Thus, when the window fixing frame 200 is maintained in a completely closed state, the first cam 130 is bitten by the second operating port 250, and the second cam 140 is bitten by the locking protrusion 270. That is, the state as shown in Fig. 5 (a) or (m) is maintained.

The present invention as described above extends the spring 150 by using the inertia generated when closing the door (window), and the safe door closing by using the return force of the extended spring 150, and the damping force of the damper 120 On the contrary, when opening, it can be easily opened with little force.

The present invention having such a configuration has the following operational relationship.

Safety closing device according to the present invention may be divided into a door opening operation made up to (a) ~ (f) of Figure 5, and a door closing operation made up to (g) ~ (m).

First, looking at the door opening operation, the window frame fixed frame 200 is pushed to the left as much as possible to maintain the closed state of the door, the user pushes the door to the right to open the door.

Then, the state is switched from the state (a) to the state (b), that is, the left side of the first locking portion 132 of the first cam 130 is applied to the second operating port 250 while applying a force, and then the direction As the second operating port 250 is rotatably installed, as shown in the figure, the first cam 130 can be crossed without being caught by the second operating port 250.

At the same time, the locking protrusion 270 keeps the second locking portion 142 and the bite state of the second cam 140 to pull the second cam 140 in the door opening direction, and accordingly, the second cam 140. ) Moves along the second guide groove 114.

In addition, at the same time, the spring 150 is pulled toward the second cam 140 as the second cam 140 moves, and the force acts on the first cam 130 again so that the first cam 130 is It is much easier to cross over the second operating mechanism (250).

As a result, the user can easily open the door by the elastic return force of the spring 150 without applying a large force.

Subsequently, if the state (f) is maintained through the processes of (c), (d) and (e), the door is opened.

That is, the second cam 140 moves while riding on the second guide groove 114 while being caught by the locking protrusion 270, and when the upper limit point in the moving direction is reached, the locking state with the locking protrusion 270 is released. 270 may continue to move in the same direction without any interference.

At the same time, the first cam 130 is in the state beyond the second operating port 250, this time the second operating port 250 is moved in the opposite direction while the operation is reversed, the first catch provided in the first cam 130 As the part 132 is turned over, the second operating hole 250 passes through, and the first cam 130 is positioned at the top-right top dead center of the first guide groove 112, and the first operating hole continuously ( In this case, the first operation tool 240 is passed in an opposite direction to the second operation tool 250.

Therefore, the interference fixing between the first and second cams 130 and 140 and the first and second operating holes 240 and 250 and the locking protrusion 270 is maintained while the window fixing bracket 200 can be opened smoothly. do.

On the other hand, as shown in (g) ~ (m) of Figure 5, when the window fixed frame 200 is closed, the opposite operation is performed as described above, the most important is the elastic return force of the spring 150 and At the same time to utilize the shock absorber of the damper 120.

That is, the first locking portion 132 of the first cam 130 is caught by the first operating port 240 is released from the right top dead center of the first guide groove 112 is moved while extending the spring 150 When the spring 150 extends to the maximum, the first cam 130 reaches the top dead center of the first guide groove 112 and at the same time, the state of engagement with the first operating port 240 is released.

Since the second operation tool 250 is a structure that can be flipped in the opposite direction of travel, even though it interferes with the first locking portion 132 of the first cam 130, the second operation tool 250 is passed without problems (j), (k), (l). ) Is possible.

At the same time, the second cam 140 meets the restraining protrusion 270 that is returned, and thus is engaged with the stopping protrusion 270 while the state in which it is stagnant at the right top dead center of the second guide groove 114 is released. At this time, since the spring 150 is returned to the maximum elongated state, the return force of the window fixing frame 200 is further increased.

In addition, at the same time, since the damper rod 122 of the damper 120 is connected to the second cam 140, the damper rod 122, which has been extended at the time of opening, returns to the damper 120 to perform a damping action and thus has a spring ( 150, even if there is a pulling force is not closed quickly but closes while slowly buffering.

Therefore, the shock can be alleviated, so that the user can perform a safe window closing operation without causing finger pinch or injury, and as described above, the window can be easily opened with a small amount of force when opening the window. Is increased.
