Description

Miseogi Changho {SLIDING WINDOW}

The present invention relates to windows and doors, and more particularly, to windows and doors that can be easily opened by sliding-type Miseogi windows and doors with little force.

In general, a window includes a window frame installed on the wall of a building and a window installed on the window frame.

These windows perform functions such as a daylighting function to let outside light into the room, a ventilation function to ventilate the indoor air, and a cooling and heating function to block heat transfer between indoors and outdoors.

Windows and doors are classified into casement windows and sliding doors according to the opening and closing method. First, the casement window refers to a window that is opened and closed while a window coupled to a window frame through a hinge rotates with the hinge as a rotation axis. These casement windows have excellent airtightness, watertightness, and wind pressure resistance, and have the advantages of easy partitioning of the facade and securing the structure.

However, the casement windows have a disadvantage in that the elevation of the windows viewed from the inside is not as beautiful as compared to the Miseogi windows, and when a special fixing device is not provided, the windows are suddenly opened or closed by the wind.

On the other hand, Miseogi windows and doors refer to windows that open and close while making a linear reciprocating motion along the rails combined with the rails provided in the window frame.

Specifically, the window frame of the Miseogi window is provided with a plurality of rails for guiding the sliding opening and closing of the window. At this time, since the rail of the window frame is formed at a constant height to support the rolling operation of the roller mounted on the lower side of the window frame, a plurality of grooves are formed in the window frame. The window sill is maintained at a certain distance from the rail of the window frame to smoothly slide against the rail of the window frame. As described above, Miseogi windows and doors have an advantage in that the elevation of the windows viewed from the inside is more beautiful than that of casement windows.

However, Miseogi windows and doors are difficult to construct compared to casement windows and have poor airtightness, watertightness and wind pressure resistance, so that the main performance of windows and doors cannot be fully performed.

In addition, the Miseogi window is difficult to open and close because the window itself is heavier than the system window.

As described above, the windows serve to allow sunlight and fresh outside indoor air to flow into the interior, thereby enabling indoor ventilation.

Accordingly, recently, ventilation devices for indoor ventilation are installed in windows and doors.

However, as described above, the ventilation device integrally installed on the windows has a very cumbersome problem because the user must manually operate the ventilation device when indoor ventilation is required.

In addition, if the ventilation device is integrally installed on the windows, the weight of the windows becomes heavier, so that it is difficult for the elderly or children to open and close the windows.

Hereinafter, with reference to the accompanying drawings, a description will be given of the window door 100 according to an embodiment of the present invention.

As shown in Figures 1 to 6, Miseogi window 100 according to an embodiment of the present invention is a window frame 102 having a rail 102a, a rail 102a in contact with the rail 102a. ) is provided between the upper end of the window frame 102 and the window frame 104 positioned above the window frame 104 and the window frame 104, which are reciprocally slid along the window frame 102 and the window frame 104, and at least one Magnetic bodies 114 and 115 are provided, respectively, and when power is applied from the outside, attractive force is generated between the magnetic bodies 114 and 115 so that the window sill 104 is raised with respect to the window frame 102. Magnetic levitation module 110; And disposed inside the magnetic levitation module 110, according to the operating state of the magnetic levitation module 110, at least a partial space between the window frame 102 and the window sill 104 is opened and includes a ventilation module 120.

1, the window frame 102 is composed of a horizontal member and a vertical member.

The window frame 102 composed of a horizontal member and a vertical member is provided with a rail 102a for enabling the reciprocating sliding motion of the window frame 104 along the longitudinal direction of the window frame 102 .

The rail 102a is generally provided at the top, bottom, and both sides of the window frame 102 . In other words, the rail 102a is provided entirely along the periphery of the window frame 102 .

The window sill 104 is reciprocally slid along the rail 102a of the window frame 102 .

At this time, when the window 104 is closed, the indoor and outdoor are blocked, and when the open state, the indoor and outdoor are communicated.

As described above, the window sill 104 is to make the Miseogi window 100 open or closed while reciprocally sliding along the rail 102a in contact with the rail 102a of the window frame 102 .

The magnetic levitation module 110 is provided in some configuration on the window frame 102, the rest of the configuration is provided on the upper end (104a) of the window sill (104).

At this time, when the lower end 104b of the window frame 102 is raised with respect to the window frame 102 by the magnetic levitation module 110, a gap is generated between the lower end portion 104b of the window frame 102 and the window frame 102. It becomes convenient to open the Miseogi window 100.

1 and 2 , the magnetic levitation module 110 includes a housing 112 , a first magnetic body 114 , a second magnetic body 115 , and a control board 118 .

The housing 112 is to be provided on the window frame 102, the magnetic levitation module 110 is located therein.

When the magnetic levitation module 110 is positioned inside the housing 112 , one side of the open surface is covered using the housing cover 112 . When that happens, the magnetic levitation module 110 is not exposed to the outside of the misseogi window 100 .

On the other hand, the magnetic levitation module 110 is provided at the upper end 104a of the window jap 104 so as to correspond to the first magnetic body 114 and the first magnetic body 114 for generating a magnetic field, and a second magnetic body which is magnetized when power is applied. It is provided on the upper side of the 115 and the first magnetic body 114 and includes a control board 118 for controlling the supply of electricity to the second magnetic body 115 .

As such, when power is supplied to the second magnetic body 115 and magnetized, an attractive force is generated between the second magnetic body 115 and the first magnetic body 114 so that the window sill 104 is raised from the window frame 102 .

Accordingly, a predetermined space is formed between the lower end 104b of the window sill 104 and the window frame 102 so that it is easy for the user to open and close the Miseogi window 100.

At this time, the magnetic levitation module 110 detects the gap between the first magnetic body 114 and the second magnetic body 115 , and includes a gap sensor 116 for transmitting the sensed result to the control board 118 .

It may be determined whether sufficient attractive force is generated between the first magnetic body 114 and the second magnetic body 115 using the air gap sensor 116 .

As shown in (a) of Figure 5, the air gap sensor 116 is a first magnetic body 114 and a second magnetic body when the window 104 of the Miseogi window 100 is in a landing state with respect to the window frame 102. Detect the interval D1 between 115.

In addition, as shown in Fig. 5 (b), the air gap sensor 116 is a first magnetic body 114 and a second when the window 104 of the Miseogi window 100 is floating with respect to the window frame 102. The gap D2 between the two magnetic bodies 115 is sensed.

For example, when the window 104 of the Miseogi window 100 is in the landing state, the distance D1 between the first magnetic body 114 and the second magnetic body 115 is about 3 mm.

In addition, when the window 104 of the Miseogi window 100 is in a floating state, the distance D2 between the first magnetic body 114 and the second magnetic body 115 is about 1 mm.

Then, a space of about 2 mm is created between the lower end 104b of the window sill 104 and the window frame 102, which is convenient when opening and closing the misogi window 100.

The magnetic bodies 114 and 115 are coupled to the bottom surface 113 of the housing 112 .

At this time, the first magnetic body 114 is coupled to the bottom surface 113 of the housing 112 using a coupling member (not shown) such as a bolt.

A plurality of first magnetic bodies 114 are disposed at predetermined intervals with respect to the bottom surface 113 of the housing 112 . At this time, one air gap sensor 116 is provided between the adjacent first magnetic bodies 114 .

Here, three first magnetic bodies 114 and three air gap sensors 116 of the magnetic levitation module 110 are provided as one set.

The first magnetic body 114 and the air gap sensor 116 provided as a set are provided to be arranged in plurality along the longitudinal direction of the window frame 102 positioned above the window sill 104 . The second magnetic body 115 of the magnetic levitation module 110 is located in the window 104 of the corresponding position.

In this case, one of the first magnetic body 114 and the second magnetic body 115 of the magnetic levitation module 110 may be provided as a permanent magnet, and the other may be provided as an electromagnet.

In the magnetic levitation module 110 according to an embodiment of the present invention, the first magnetic body 114 is provided as a permanent magnet, and the second magnetic body 115 is provided as an electromagnet.

Accordingly, when power is applied to the second magnetic material 115 by the control board 118 , the second magnetic material 115 is magnetized and moves toward the first magnetic material 114 generating a magnetic field.

This??, the window frame 104 is moved toward the upper window frame 102 , and the lower end of the window frame 104 is raised in a direction away from the lower end of the window frame 102 .

Then, by forming a space between the lower end of the lower end of the window frame 102 and the lower end of the window frame 102, the user can open the window 100 by moving the window seat 104 without applying great force.

On the other hand, when a space is formed between the lower end of the window frame 102 and the lower end of the window frame 102 by rising from the lower end of the window frame 102, the window sill 104 is airtight, sealing, and A problem arises in maintaining basic performance such as insulation.

In order to solve this problem, the space formed between the lower end of the window sill 104 and the window frame 102 should be filled.

To this end, referring to FIG. 5 , sealing members 101 and 103 are provided at the lower end of the window sill 104 . The sealing members 101 and 103 are for sealing the space formed between the lower end of the window sill 104 and the window frame 102 .

The sealing members 101 and 103 include a mohair 101 and a gasket 103 .

The mohair 101 is provided at the lower end of the window sill 104 , and is provided at a portion in contact with both ends of the rail 102a of the window frame 102 . In other words, the mohair 101 is provided at both ends with respect to the rail 102a of the window frame 102 .

Since the mohair 101 has a relatively small frictional force than other sealing members, there is an advantage that the window sill 104 can be smoothly slid with respect to the rail 102a of the window frame 102 .

In addition, the sealing members 101 and 103 are provided at the lower end of the window sill 104 , and the gasket 103 is provided at a portion not in contact with the rail 102a of the window frame 102 .

The gasket 103 is formed of a rubber material.

The gasket 103 is provided on one surface of the lower end of the window sill 104 , and the mohair 101 is provided at the lower end of the window frame 104 , and is formed in a portion in direct contact with the rail 102a of the window frame 102 .

As the lower end 104b of the window frame 104 is raised with respect to the window frame 102, the gap formed between the lower end of the window frame 104 and the rail 102a of the window frame 102 is formed between the mohair 101 and the gasket 103. This results in a completely sealed state.

On the other hand, as shown in FIG. 6 , the window door 100 according to an embodiment of the present invention further includes a ventilation module 120 .

Here, in the ventilation module 120 , at least some space between the window frame 102 and the window sill 104 is opened according to the operating state of the magnetic levitation module 110 .

In other words, when magnetic force is generated in the magnetic levitation module 110, the space of the ventilation module 120 is closed, and when the magnetic force is not generated in the magnetic levitation module 110, the space in the ventilation module 120 is opened.

At this time, the polluted indoor air is discharged to the outside through the space formed in the ventilation module 120 , or the outdoor air is introduced into the room through the space formed in the ventilation module 120 .

On the other hand, if the ventilation module 120 does not generate an attractive force between the first magnetic body 114 and the second magnetic body of the magnetic levitation module 110, the ventilation module 120 is in an open state so that indoor air is discharged to the outside. .

In addition, if the ventilation module 120 does not generate an attractive force between the first magnetic body 114 and the second magnetic body 115 of the magnetic levitation module 110 , the ventilation module 120 is in an open state to send indoor air to the outdoors. discharge

Conversely, as shown in FIG. 6 (b), when the attractive force is generated between the ventilation module 120 and the first magnetic body 12 and the second magnetic body 14 of the magnetic levitation module 110, the ventilation module ( 120) is closed, making it impossible for indoor air to be discharged to the outside.

On the other hand, the ventilation module 120 is provided in the window frame 102 at a position corresponding to the first body portion 122 and the first body portion 122 provided inside the window pane 104, and a second magnetic body ( 115) provided in the second body portion 126, the first coupling portion 124a provided in the first body portion 122, the second body portion 126 provided in the first coupling portion (124a) The second coupling portion 124b formed at a position corresponding to and between the first coupling portion 124a and the second coupling portion 124b include an air passage provided so that indoor air is discharged to the outside or real air is introduced. .

For reference, the air passage means a flow path between the first coupling part 124a and the second coupling part 124b.

At this time, when an attractive force is generated between the first magnetic body 114 and the second magnetic body 115 , the air passage is blocked when the first coupling part 124a and the second coupling part 124b come into contact, and the first magnetic body 114 . ) and the second magnetic body 115, if no attractive force is generated, the indoor air is discharged to the outside or the outdoor air is introduced into the room.

Here, the first coupling portion 124a and the second coupling portion 124b are in contact with each other in which power is applied to the magnetic levitation module 110 , and when power is not applied to the magnetic levitation module 110 , the contact state is released

On the other hand, although not shown in the drawings, the ventilation module 120 is provided with a filter member (not shown). The ventilation module 120 filters fine dust or contaminants included in the outdoor air flowing into the room through the air passage.
