Description

{Sliding windows having windbreak device using crescent}

[0001] The present invention relates to a door for a door having airtight means using a crisscant, and more particularly, to a door for opening and closing a door by intercepting a lateral air flow through a space between a rail and a rail using a crisscenk, And to a technique for improving airtightness and insulation efficiency.

A window is a window and a door which isolates the room from the outside and blocks the wind. The window is used for ventilation of the room or for the ventilation of the room. The structure is fixed to the window frame (or door frame) (Or door) that is mounted so as to be mounted.

On the other hand, Changhee recently enforced the energy efficiency rating system that has been applied to household appliances and automobiles since July 1, 2012. This is due to the fact that about 40% of the building energy is being counted through the window, Labeling of consumption efficiency grade was attached. The window manufactured according to the window energy efficiency rating system is divided into classes 1 to 5 according to the efficiency of energy consumption, and labels are displayed so that the consumer can easily distinguish the energy saving window and purchase the product, Or products that are below minimum efficiency standards are prohibited from manufacturing and selling.

Because of this window energy efficiency rating system, window makers are currently conducting a lot of research to obtain window rating with high efficiency of heat conduction rate and confidentiality.

More specifically, various categories of windows will be discussed below.

Depending on the opening method, the window may be classified into a hinged or sliding type or a fixed type. Among the hiding methods, there is a system window method which is widely used in Europe and the United States as a method of high airtightness and heat insulating force. In the case where the handle is operated in a window, it is mainly tilt and turn It is a window.

In addition, the material used to construct the window frame (window frame) and the window (door) of the window has conventionally been a simple wood, but recently, a material such as aluminum and synthetic resin such as polyvinyl chloride (PVC) . Because aluminum does not cause oxidation, such as decay, deformation or iron like wood, it is usually applied to a veranda. However, aluminum has a disadvantage in that the heat insulating effect is deteriorated due to the high thermal conductivity and the sound insulation and insulation effect is deteriorated due to generation of clearance at the assembled part during long-term use due to thermal deformation. In contrast, synthetic resin is superior to aluminum in its insulation effect, and in most cases it is installed at the boundary between living room and veranda.

Also, recently, the construction of a composite window using a mixture of the metal material and a synthetic resin material is also increasing. Such a composite window is a window which is combined with a synthetic resin material having excellent heat insulation performance and capable of expressing various colors in order to overcome the problem that the insulation performance which is a disadvantage of metal material is low and various colors and patterns for interior use are restricted.

Meanwhile, in order to increase the energy efficiency grade, airtight and heat insulation techniques of conventional window glasses have been developed by installing a mohair or a windshield structure at a boundary between a window and a window frame to block air flow, A technology for blocking the heat conduction by forming a hollow structure, and a technique for blocking the airflow flowing in the lateral direction of the window frame frame by installing a horizonward plate at the middle portion of the window portion where the window and the window overlap.

9 is a side cross-sectional view of a window in which a horizontal wind-surfaced plate and a mohair are installed. In order to prevent airtightness through a space between a rail and a rail formed on a window frame, a conventional lower window is formed in a lower space of an opening portion where the window 600 and the window 600 intersect with each other, A horizontal swing plate 400 is installed at a portion where the window 600 and the window 600 overlap each other in the clearance space between the rail 800 and the rail 800 formed on the upper and lower sides of the door 500, .

The wind plate 400 is inserted horizontally into the space between the lower rail and the rail of the presser foot, and a plurality of wind-preventing wings 401 are inserted into a space And a plurality of such rows are arranged along the horizontal direction (rail direction).

In addition, the wind-preventing blades are arranged to be offset from neighboring neighboring rows. At this time, since the shape of the wind-preventing blade is staggered, the inflow air flows along the complicated flow path and is annihilated, and the movement of the insect is also blocked, thereby increasing the airtightness and heat insulation power, .

In addition, in the vicinity of the rail where the roller 700 is installed, mohair is provided inside the skirt in which both sides of the window are lowered toward the rail, thereby blocking the flow of air flowing into the rail.

However, most of the techniques using the above-described conventional windshield plates or mohair are techniques in which a hermetic member or a wind-up member is fixedly installed or formed for airtightness or insulation of a peripheral portion on the inner side of a windowpane frame or a rail, There is a technical disadvantage that the airtightness and the thermal insulation structure can not be provided by completely sealing the lateral air passage through the opening portion of the air flow entering the room from outside the room.

The reason for such a disadvantage is that the rollers installed on the windows on the window structure slide smoothly on the rails. When the spaces between the rails and the rails are sealed for airtightness on the opening portion, contact frictional force This is because the shutter window can not slide smoothly.

For this reason, most airtight and heat insulating members in the prior art do not have a completely closed structure, so there is a limit to providing airtightness and heat insulating capability.

On the other hand, a conventional door window is structured such that a crisscent portion is provided on the side of the opposite window of the opening portion of the opening of the door with a locking device to perform a locking action for crime prevention. When the window 600 is closed, the window 600 is fixed to the window 600 by a rotary locking device installed on the side of the window 600 to be overlapped.

In a general structure, a side surface of the indoor side window 600 on the opening of the window 600 is provided with a criss-stop lever, a crisscant rotating shaft for rotating the criss-in-the-lens lever, A crescent fixing part fixed to the side of the window so as to fix the cen- troid rotation axis, and a catching part formed with a bent hook having a bent end at one side of the outdoor side window 600 installed at the corresponding position.

When a crease lever installed on the side of the window 600 located near the indoor side is caught by the catch provided on the side of the window 600 near the outdoor side by rotating around the crisscenter rotation axis, The leftward and rightward movement of the left-right direction is interrupted.

However, since the above-mentioned crisscents are mainly used for the locking function, the structure for preventing the airtightness and insulation of the window glass is not applied, and thus it is necessary to improve the energy efficiency rating of the window glass.

FIG. 2 is a cross- FIG. 3 is a perspective view showing a state before operation of one side airtight means according to an embodiment of the present invention, and FIG. 4 is a perspective view showing a state after operation of one side airtight means according to an embodiment of the present invention FIG. 5 is a perspective view showing the structure of the other airtight means according to the embodiment of the present invention, and FIG. 6 is a side view showing a state before operation of the one airtight means according to the embodiment of the present invention. FIG. 7 is a side view illustrating a state after operation of one side airtight means according to an embodiment of the present invention, and FIG. 8 is a front sectional view illustrating a structure of one side airtight means according to an embodiment of the present invention .

As shown in the figure, the configuration of the unseasonable window according to an embodiment of the present invention includes a window frame 500 and a pair of left and right window pads (left and right side windows) that are installed on the window frame 500 and slide left and right by a roller 700 mounted on the rail 800 600).

However, the window frame 500 according to the present invention has a cross-sectional shape having the same or similar width between the rail 800 and the rail 800 formed at least at the indoor side window frame 500 when the window pane 500 is constructed as a double- Is formed to divide the upper and lower space portions of the window frame.

In addition, at least the rail 800 located on both sides of the auxiliary rail 801 of the rail 800 has a sectional shape so that the side surface thereof can be brought into contact with the airtight plate of the crimin airtight means to be described later, It forms.

The window 600 is slid along the rail 800 formed on the window frame 500 and the lower end and the upper end of the windowpane 600 of the indoor side 600 are slidably mounted on the upper and lower portions of the window frame 500, The upper auxiliary rail groove 601 and the lower auxiliary rail groove 602 are formed in the direction of the auxiliary rail 801 of the upper and lower window frames so as not to collide with the respective auxiliary rail 801, The window frame portions on which the auxiliary rail grooves are not formed are formed so as to be adjacent to each other and close to the side windowpanes 600 facing each other. When the crisscross lever of the crisscross portion 10 to be described later rotates and is hooked by the latching hooks to cause a locking action, the opposite pair of the windowpane 600 is pulled so that the window surface is closely contacted to be interfaced with the airflow gap Thereby exerting a confidential force.

The side air tightness through the space between the rail 800 and the rail 800 in the case where the window 600 having the above structure is provided is solved by the cleanscent airtight means to be described later, The airbag will increase the sealing force and provide the air window with high airtightness and insulation efficiency.

The crisscant hermetic means installed in the window of the present invention is not limited to the left and right moving interrupting action of the window 600 such as the known crisscenter device described above and also the flow of air flowing in the direction of the rail 800 of the windowpane 500 Which is a device capable of complicating the airtight action of interrupting the air.

Hereinafter, only the cleaner airtight means exposed to the indoor side in the opening of the opening portion will be mainly described, but the cleaner airtight means is installed and operated in the outdoor side window 600 of the opening unit.

In addition, the crease air tightness means provided on the opening portion is mostly the same on the indoor side and the outdoor side, but unlike the indoor side on the outdoor side 600, only the crease cent levers, the crease centric rotary shafts, And the window pane 600 corresponding thereto is different from the window pane 600 in that no separate latching piece is provided. The reason why the latch members are removed from the crisscents of the crisscant airtight means provided in the left and right windowpane 600 is that the outdoor side crisscante airtight means is configured to operate in a state in which the one side window 600 is opened, This is because the airtight means is configured to operate in a state in which both the side mirrors 600 are closed.

The opening of the window frame 500 is closed to block the side airflow of the space between the window 800 and the auxiliary rail 801 and the space between the adjacent windows 600 in the space between the rails 800, The indoor side creature airtightness means of the creatin airtight means formed on the indoor side and the outdoor side of the window 600,

A crisscross lever 11 provided on one side of one side of the one side window 600 and a crisscent rotation shaft 12 formed through the windowpane 600 so as to be interlocked with the crisscross lever 11 when the crisscross lever 11 rotates, (13) fixed to the side surface of the window by means of piece coupling so as to fix the crisscross rotation axis (12) and the crisscross rotation axis (12) on the side of the windowpane (600) And a crease member 10 made of a locking piece 14 provided on the other side window.

And a circular gear portion 20 that is axially coupled to the crisscent rotation shaft 12 within the one side of the windowpane 600 is provided.

The upper gear bracket 30 and the lower gear 30 are symmetrically arranged in the vertical direction with respect to the center of the circular gear portion 20 and are gear-engaged and configured to move in different directions when the circular gear portion 20 is rotated. A bracket 40 is provided.

And an upper rod 50 and a lower rod 60 which are respectively coupled to the upper gear bracket 30 and the lower gear bracket 40 and are formed to have a required length according to the length of the window.

And is lifted or lowered through the upper opening 603 and the lower opening 604 respectively formed on the upper surface and the lower surface of the window 600 and provided at the end portions of the upper rod 50 and the lower rod 60 And an upper airtight plate 70 and a lower airtight plate 80 which are in contact with the window frame surface to perform a hermetic action.

The crisscross portion 10 has a protruding portion of the crisscross lever 11 when the crisscross lever 11 provided on one side of the indoor side window 600 on the opening portion rotates in the locking direction The front end of the engaging piece 14 formed on one side of the outdoor side window 600 located on the same plane enters and engages with the bent catch ring. The difference is that the crisscross rotation axis 12 is fixed to the window 600 And has a construction in which it penetrates from the criss-stop fixture 13 fixed by a piece of a screw or the like to the inside of the window 600 frame. The reason for constructing the crisscross rotation axis 12 so as to be long is to rotate the circular gear 20 by the driving source of the crisscross lever 11.

The circular gear portion 20 is formed with a plurality of gear teeth 21 around a cylindrical structure and the pitch of the gear teeth 21 is set to a gear groove formed in the upper gear bracket 30 and the lower gear bracket 40 . That is, if you want smooth operation, you can make the pitch small, and if you want it to work fast, you can increase the pitch. The shape of gear teeth can be triangular, square or elliptical in cross section if they are caught in the gear groove.

When the center portion of the circular gear portion 20 having such a shape is axially coupled to the crissenter rotation shaft 12 and the crisscrant lever 11 is rotated to the lock position, 21 and the gear-coupled upper gear bracket 30 are raised, and the corresponding lower gear bracket 40 is lowered.

The upper gear bracket 30 and the lower gear bracket 40 are formed in a vertical bar shape and the upper end of the upper gear bracket 30 and the lower end of the lower gear bracket 40 are bent. Gear grooves 311 and 411 are formed in the vertical portions 31 and 41 of the upper gear bracket 30 and the lower gear bracket 40 at pitches corresponding to the gear teeth 21, Fastening grooves 321 and 421 are formed in the horizontal portions 32 and 42 of the lower gear bracket 40 and the lower gear bracket 40 so that the upper and lower rods 50 and 60 are inserted and fixed respectively. According to the illustrated embodiment, the upper rod or the lower rod is inserted into the groove formed in the horizontal portion and is fixed by a nut coupling or the like. However, the present invention is not limited to the illustrated fixing methods.

Further, a guide bar (not shown) or the like can be formed on the frame 600 for stabilizing the upward and downward movements of the upper gear bracket 30 and the lower gear bracket 40, if necessary.

The upper and lower rods 50 and 60 are moved up and down by the upper gear bracket 30 and the lower gear bracket 40 by the operation of the circular gear portion 20, The upper end of the upper rod and the lower end of the lower rod are combined with the upper airtight plate 70 and the lower airtight plate 80, respectively. At this time, although the joining portion is not limited, it is structurally stable that the upper and the lower airtight plate 70 and 80 are coupled together.

In particular, the upper airtight plate 70 and the lower airtight plate 80 can be further pressed and contracted in a state of being in contact with the window frame surface in order to raise the sealing force when the window frame surface is raised or lowered. Stoppers 51 and 61 are provided between the upper rod and the upper airtight plate and between the lower rod and the lower airtight plate so as to provide a stable elastic force so as to provide a uniform hermetic force continuously, while preventing the lower airtight plate from being damaged or deteriorated in durability Buffer springs (52, 62) are formed along the circumference of one point of the upper rod (50) and the lower rod (60) or over a part of the circumferential section to be supported by the stopper, and the upper airtight plate To provide a buffering force to the plate (80).

The buffer springs 52 and 62 normally maintain a state in which the pitch has a sufficient shrinkage capability, and the upper rod 50 and the lower rod 60 move upward or downward so that the upper and lower gas- The upper airtight plate 70 and the lower airtight plate 80 are further contracted to provide a buffering force and a continuous pressing force for protecting the upper airtight plate 70 and the lower airtight plate 80 Thereby increasing the airtightness.

The upper airtight plate 70 and the lower airtight plate 80 are spaced apart from each other in a space between the rails 800 formed on the window frame 500 in detail by a space between the rails and the auxiliary rails, Shaped cushioning material having a shape corresponding to the shape of the window 600 so as to be kept in the upper opening 603 and the lower opening 604 formed on the upper surface or the lower surface of the window 600, The protrusions are protruded from the upper opening 603 and the lower opening 604. The material is preferably a synthetic resin material having excellent weather resistance, elasticity and durability including EPDM.

The upper airtight plate 70 and the lower airtight plate 80 formed in a plate shape necessarily have rail grooves 71 and 81 corresponding to the height and width of the rail 800 due to the structure of the rail 800 formed on the window frame 500 ), It is formed as close as possible to the rail 800 so as to increase the airtightness by increasing the contact force with the rail. In order to increase the airtightness between the upper airtight plate and the lower airtight plate, the side surface of the rail 800 has a cross-sectional shape in contact with the upper airtight plate 70 and the lower airtight plate 80, Plane.

The operation of the present invention configured as described above will be described below.

The user closes the left and right windowpane 600 and moves the left and right windowpane 600 in the same one direction first to increase crime prevention and airtightness. It is pushed all the way to the left with reference to the drawing of the present invention shown in accordance with one embodiment. Thereafter, the creature lever 11 of the creature unit 10 exposed to the outside among the components of the creature airtight means located on the outdoor side of the shutter unit is rotated in one direction. The circular gear portion rotates the circular gear portion 20 so that the upper gear bracket 30 and the lower gear bracket 40 are engaged with the upper gear bracket 30 and the lower gear bracket 40, respectively, So that the upper rod 50 and the lower rod 60 connected to the upper rod 50 are linearly moved. The upper airtight plate 70 and the lower airtight plate 80 coupled to one end of the upper rod 50 and the lower rod 60 are moved to the upper opening 603 and the lower opening 603 of the window, 604 so as to block the spaces between the rails and the auxiliary rails on one side of the opening portion formed sequentially in the window frame.

When the operation of the clean room airtightness means of the one side window of the shutter is completed, the indoor side window is moved to the right side. When the indoor side window bar is pushed in this manner, the crisscross portion 10 located on the other side of the presser panel and the retaining piece 14 provided on the other side of the window pane corresponding thereto are seen. In this state, the creature lever 11 is rotated to be attached to the engaging piece 14. When the crisscross lever is rotated, the crisscross rotation axis 12 rotates to rotate the circular gear portion 20 as described above. The circular gear portion is engaged with the upper gear bracket 30 and the lower gear bracket 40, The upper rod 50 and the lower rod 60 connected to the upper rod 50 and the lower rod 60 are linearly moved. The upper airtight plate 70 and the lower airtight plate 80 coupled to one end of the upper rod 50 and the lower rod 60 are moved to the upper opening 603 and the lower opening 603 of the window, 604 so as to block the spaces between the rails and the auxiliary rails on one side of the opening portion formed sequentially in the window frame.

At this time, when the indoor airtight sealing plate 70 and the airtight sealing plate 80 are in contact with the window frame surface of the opening and closing the space between the rail and the auxiliary rail formed on the upper and lower window frames, The spaces between the rails and the auxiliary rails formed in the upper and lower window frames closed by the lowered airtight plate 70 and the lower airtight plate 80 together with the spaces between all the opening / closing rails and the auxiliary rails are sealed, The heat insulating force is increased.

Furthermore, since the upper and lower portions of the indoor side window are formed in the upper and lower auxiliary rail grooves in the longitudinal direction along the auxiliary rail to have a structure such that the auxiliary rail is housed, the space between the upper auxiliary rail and the lower auxiliary rail The airtightness efficiency is improved because the structure of the indoor side window in the opening portion of the window is made close to the gap between the outdoor side window facing the outdoor side window. In addition, even when the crisscrant lever is rotated by the rotation of the window, the gap between the window and the window is pulled by the gap between the window and the window so that the airflow is more likely to occur The clearance itself is almost completely eliminated, providing a near perfect seal.
