DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window in a building such as a house, and more particularly, to a window in a cold area where indoor heat insulation is required. It is about double windows.

[0002]

2. Description of the Related Art As a conventional double window using a blind together, a sliding door type is generally used. As a window provided with a hinge-opening type blind having high heat insulation, the window shown in FIG. 8 is used. I have. That is, as shown in FIG. 8, a conventional opening / closing window provided with a blind is provided with an upper frame 1 around an opening of a wall surface.
0, the lower frame 11 and both side frames 12 are attached to form a window frame,
A window W comprising a high-insulation double-glazed glass plate 21 stretched in an airtight state and comprising upper and lower frames 20 and left and right vertical frames 20 '.
_One of the vertical frames 20 'is attached to the side frame 12 so as to be freely opened and closed with a hinge, and the head box 51 of the blind 5 is attached to the upper edge of the opening on the indoor side wall.

[0003] and, blind at the time of closing of the window W ₀ 5
While rising opening and descending closure of a free, when opening the window W ₀ to the indoor side, the window W ₀ rises opening the blind 5
It is necessary to avoid interference with the opening movement of the vehicle.

[0004]

In the conventional inward opening window shown in FIG. 8, the opening / closing operation of the window is hindered by the blind being used in a hanging operation, and the blind is raised and opened prior to opening / closing the window. Was needed. Also, regarding the installation work on the building, the installation of the blinds was one of the hindrance factors for shortening the construction period, because the installation of the windows and the installation of the blinds were carried out by different types of workers at different times on the schedule. .

Further, since the blind 5 is provided so as to protrude from the wall surface toward the interior of the room, it hinders the activity of the resident (especially a child) in the room, and the splash of the blind is often damaged. In addition, indoor dust adheres to the splashes of the blinds and is easily stained. The present invention solves the above-mentioned problems at a glance by suspending an elevating blind inside a double window.

[0006]

Means and action for solving the problem For example, FIG.
(A), as (B), the opening and closing times each independently
Communicating with a dynamic possible inner windows W ₁ and the outer window W ₂ protrudes from one window
The lifting blind 5 is engaged with the connecting rod 43 in a detachable manner.
Was mounted between both windows W ₁ and W ₂ and on one window frame so as to be able to move up and down from the indoor side of the inner window W ₁ . Therefore, the inner window W ₁
And the outer window W _2, opening and closing as a double window remains hanging blind 5 together by the connecting rod 43 is possible.

Further, since the opening and closing of the blind 5 is performed between the double windows by an operation from the indoor side, the blind 5 is hardly stained. In addition, one and the inner window W ₁ and the outer window W ₂
Can be disengaged by the connecting rod 43 protruding from one of the windows, so that the windows W ₁ , W ₂ and the blind 5 can also be cleaned with the double windows opened as required, even when the double windows are opened. Then both windows
It can be easily implemented by separately opening and rotating W ₁ and W ₂ . Moreover, spatial S between the inner window W ₁ and the outer window W ₂
Acts as a heat insulating layer, and for interrupting a blind before the passage of the inner windows W ₁ to sunlight rays, it is possible to reduce the cooling load during summer indoor cooling.

Further, since the lifting blind 5 is hung on the outside of the inner window frame 2 and the opening / closing grip 53 and the lifting cord 54 are hung down to the inside of the room via the fastener 55, the blind 5 is used as an operating tool of the blind 5. The opening / closing grip and the lifting / lowering cord can be arranged in a beautiful manner and the appearance is not impaired. Of course, since these operating tools are merely inserted from one surface of the inner window frame 2 to the other surface, mounting and handling are easy.

Further, since the outer window frame 4 and the inner window frame 2 are removably engaged with the stopper 6 slidably mounted with the connecting rod 43 protruding from one side, the double-window opening / closing operation is performed. sometimes, in the form of an inner window W ₁ and the outer window W ₂ is kept apart by a connecting rod 43, and sliding motion that occurs between the window absorbs stopper 6 is slid, the opening and closing of double windows It can be performed smoothly.

The stopper 6 is slidably fitted to a rail 64 fixed to the inner window frame 2, and a mounting piece 65 is mounted to the inner window frame 2 via an adjustment hole group 64 h provided on the rail 64. As a result, since the sliding amount L of the stopper 6 was regulated,
The opening amount of the double window can be specified, and the opening amount of the double window can be adjusted by selecting and determining the mounting position of the mounting piece 65.

When the double window is closed, the outer window frame 4 is closed.
Inside the upper and the gap G ₂ between the outer window upper frame 31, the outer window stile 4 of the lower and the gap G ₁ between the outer window sill 32, and double glazing through the drainage hole of the outer window sill 32 Since the space S communicates with the outside air, dew condensation on the inner surface of the outer window glass plate 41 and the outside of the inner window glass plate 21 can be preferably prevented, and the air between the inner space S of the double window and the outside air can be prevented. Since the amount of communication is small through upper and lower gaps and drain holes of the double window, the space S inside the double window functions as a heat insulating layer for air.

Further, since with a multi-layer glass plate 21 inner window W ₁ is installed in a vacuum-tight state, and double-glazed windows are open on the interior side, the heat insulating function of the double glazing is greater, double It is easy to clean the inside of the window when it is opened indoors, that is, when it is pulled into the room, and when the double window is opened to the indoor side, the maintenance of the open state of the window comes off, so there is an unexpected situation. In addition, there is no danger of indoor persons (especially children) falling from windows.

Of course, in order to prevent the lever 63 from being blinded, the sliding plate 63b and the support 63c of the lever 63 are pressed against the stopper main body 61 and the cover body 62 so as to receive the elastic resistance and the material properties and the respective materials. The relevant dimensions have been designed.

[Operation of Double Window] As shown in FIGS. 2A and 2B, when the connecting rod 43 attached to the outer window frame 4 is engaged with the stopper 6 of the inner window frame 2, the inner window W ₁ and the outer window W ₂ integrally opened and closed as a double glazing via respective hinges 23 and 42. However, since there is a fixed distance between the hinges 23 and 42, that is, a distance corresponding to the thickness of the double window, as the double window is opened, there is a relative displacement between the two windows, and the double window becomes 90 °.
When opened, a shift corresponding to the distance between the hinges 23 and 42 occurs between the inner window side end and the outer window side end.

Therefore, by selecting the mounting position of the mounting piece 65 of the stopper 6 at an appropriate position of the adjustment hole group 64h on the rail 64, the sliding amount of the stopper body 61 on the rail 64 can be defined. can define the slip amount of the external window W ₂ respect to the inner window W ₁ by the opening of the heavy window, it limits the opening angle of the double-glazed windows can be specified.

In order to release the engagement between the inner window W ₁ and the outer window W ₂ , the lever 63 of the stopper 6 is pulled out from the stopper main body 61 with the double window opened, so that the T on the outer window side is released. The character-shaped head 43a comes off from the stopper 6, and the engagement between the windows can be released. Moreover, the lifting and rotating operation of the vanes 52 of the blind 5 is at the closing time and opening of double glazing as well as freely even when releasing the engagement of the inner window W ₁ and the outer window W ₂ is there.

[0027] [Others] It is also possible to hanging blind 5 to the inside of the outer window W _2. In this case, the installation of the blind operating device (lift cord) but is complicated, the longitudinal member upwardly to the stop member 55 of the inner window stile 4 of the window W ₁ hinge mounting side
By installing a no problem even when releasing the engagement between the inner window W ₁ and the outer window W _2. However, even when the hanging blind 5 to the outer window W _1, the mounting position of the stopper 6 and T-shaped rod 43, to the opposite side, i.e. the large side of the opening and closing movement of the window hinge mounting position (FIG. 2) However, it is convenient for disengagement work. Of course, it is also possible to attach the stopper 6 to the outer window frame 4 and the connecting rod 43 to the inner window frame 2.

[0028] When suspended from a blind 5 to the inner surface of the outer window W ₂ is different from the case where suspended from the inner window W ₁ side, when the blinds, the space S between the double glazing The temperature rise can be suppressed lower, and the cooling load in summer can be reduced. In addition, if the blind 5 is raised during heating in winter, the function as a heat insulating layer of the space S between the double windows can be achieved by using the inner window as the inner window. it is identical to that of the case of suspended from the W ₁ side.

As means for engaging and disengaging the inner window W ₁ and the outer window W ₂ , the lever 63 of the stopper 6 can be omitted by rotating the T-shaped head 43 a of the connecting rod by 90 °. Instead of the stopper body 61, the lever 63, and the rail 64, the rail 64 is a member having a long groove for sliding. The T-bar is slid while being held in the long groove for sliding, and is used for regulating the sliding amount of the T-bar. It is also possible to employ alternative means such as arranging the pin insertion holes at regular intervals of the sliding holes so that the pins penetrate to an arbitrary position.

[0030]

[Effect of the Invention] because it is suspended in the window stile between the blind 5 is the inner window W ₁ and the outer window W _2, you can open the window even while blinds, also blinds hanging inside the window Because it is lowered, the splashes of the blinds are less contaminated, and the blinds do not disturb the indoors. In addition, since the blind shields external solar radiation before entering the room, the cooling load during indoor cooling in summer can be reduced. Also,
With the double window open, the connecting rod 43 is used to open both windows W ₁ and W ₂ .
When the engagement is released, both windows W ₁ and W ₂ can freely rotate separately
Cleaning of both windows W ₁ , W ₂ and blind 5
Easy to implement.

Further, the space S in the double glazing, because there is a slight air convection from the upper and lower edge of the outer window W _2, double glazing inside the condensation can be prevented, yet the space S functions as a heat insulating layer And the propagation of external noise into the room can be significantly reduced. In addition, since the blinds are constructed as part of the windows, the number of man-hours for blind construction can be reduced, and the completion period of the building can be shortened.
