Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a double window device that can be opened and closed.

(Prior Art) A double-glazed window device is known in which a window device that can be opened and closed is placed further away from the window device that can be opened and closed to improve sound insulation and heat insulation. Such double-glazed windows come in two types: those in which the inner and outer windows are assembled together in advance, and those in which the inner windows are assembled later; however, both types of double-glazed windows improve the sound insulation and heat insulation effects for the room. In order to
The airtightness of the inner windows is set to be sufficiently higher than that of the outer windows. As a result, the current situation is that inner windows share more of the external wind pressure than outer windows.

In addition, in the case of double-glazed windows with an inner window installed later, the inner window is less rigid and strong than the outer window in order to reduce the cost of the inner window and prevent condensation.For example, the outer window is made of aluminum sash. The interior windows were made of wood or plastic.

(Problem to be solved by the invention) By the way, if the airtightness of the inner window is higher than that of the outer window, the sharing force of the outside air wind pressure acting on the inner window is greater than that of the outer window, so a large wind pressure will be generated. When this occurs, the deformation of the inner window becomes larger than that of the outer window, giving the occupants a sense of anxiety. This becomes more noticeable when the stiffness and strength of the inner window are lower than those of the outer window.

If the wind pressure sharing force of the inner window is greater than that of the outer window, and the rigidity and strength of the inner window is lower than that of the outer window, the risk of the inner window breaking due to wind pressure is greater than that of the outer window. may be significantly higher than that of

The present invention has been made to solve the above problems, and its purpose is to maintain a higher airtightness of the inner window than the outer window in normal times in a double window device that can be opened and closed. To provide a double-glazed window device which automatically lowers the airtightness of an inner window so that the wind pressure sharing force is approximately commensurate with the rigidity and strength of the inner window during strong winds.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an openable and closable window device in which the airtightness of the window device supported by the inner window frame is set higher than the airtightness of the outer window device. In a double window system, when both the inside and outside window systems are closed and the outside air pressure acting on the inside window system exceeds a predetermined value, a gap is formed in conjunction with a predetermined amount of deformation of the inside window system. The gist is that a gap forming mechanism is provided between the inner window body and the window frame, and the gap forming mechanism constitutes airtightness reducing means for reducing the airtightness of the inner window device.

(Embodiments) Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a partial perspective view of a double window device. Inside the outer window device 1 consisting of left and right window bodies 2 and 3 that can be opened in both directions, there are further window bodies 5 and 6 on the left and right windows that can be opened in both directions. An inner window device 4 consisting of the following is provided, and a window glass 2b is fitted into the stile 2a of each window body 2. Although not shown, the window frame and each window frame 2a

On the other hand, a piston hole 58 is formed in the middle part of the doorstop surface 57 of the vertical frame 56 of the window frame, a space 61 is formed in the wall body 60 to which the vertical frame 56 is fixed, and a coil spring 63 is inserted into this space 61. The piston 62, which is strongly elastically biased, is housed. This piston 62 faces into the piston hole 58, and is normally prevented from moving forward at the lower end of a stopper 64 which is swingably supported on the door stop surface above the piston hole 58. The stopper 64 is engaged in the engagement recess 54 of the protrusion 53.

In the figure, numeral 59 is a piston guide, and thick rubber airtight members 65, 65 having a convex cross section are fitted over the entire length on the left and right sides of the door stop surface 57.

FIG. 13a is a front view showing the state of engagement between the piston 62 and the stopper 64 under normal conditions.

With this configuration, when a large external wind pressure acts on the inner window body, the middle part of the vertical stile 51 is bent, so that the stopper 64 that engages with the engagement protrusion 53 provided on the vertical stile 51 is The piston 62 rotates as shown in FIG.
The piston 62 moves forward due to the strong springing force of the vertical stile 51. Therefore, as shown in FIG. 14, the vertical stile 51 is pushed by the piston 62 and separated from the vertical frame 56, and the inner window is forcibly opened, and the vertical frame 56 and vertical frame 51 are automatically separated. A gap S will be created between them.

The return of the piston 62 is achieved by pushing the piston 62 back and locking it again with the stopper 64.

In each of the above embodiments, a non-powered airtightness reducing means utilizing deformation of the inner window is employed, but of course a pressure sensor, a solenoid valve, etc. may also be employed.

(Effects of the Invention) As is clear from the above description, according to the present invention, in a double window device that can be opened and closed, a gap is automatically formed between the inner window device itself or the inner window body and the window frame during strong winds. Since the structure is configured to reduce the airtightness of the inner window device, it is possible to prevent large deformation of the inner window during strong winds and eliminate the feeling of anxiety among residents, and also to prevent the inner window from breaking due to wind pressure. Risks can also be eliminated.
