Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a rotating window with a double glass structure, and its purpose is to facilitate cleaning between the two glasses. .

[Conventional technology]

Conventionally, windows with a double glass structure have been generally used to enhance the heat insulation effect, and a similar structure is also used in rotating windows.

[The problem that the idea attempts to solve]

However, in windows with this type of structure, condensation may occur due to the temperature difference between the two panes and the outside air, or dust in the air may enter between the panes due to the intrusion of rainwater, albeit a small amount. There is a problem in that the adhesion not only reduces the lighting function of the glass but also impairs the aesthetic appearance of the window.

[Means to solve the problem]

This idea was made with the intention of solving the above problem, and the shoji that is fitted inside the window frame,
It is composed of an inner shoji that is rotatably supported with respect to the window frame, and an outer shoji that is swingably supported at the lower part of the inner shoji, and the inner and outer surfaces of the swinging support parts of the inner and outer shoji Attach a pair of handles to the
The penetrating shaft of the handle is thrust from each shoji toward the other shoji, and the square shaft portion provided on the other penetrating shaft is removably fitted into the engagement recess provided on the one penetrating shaft, and This paper proposes a rotating window in which a locking/unlocking means is connected to one of the through shafts.

[Effect]

In the rotating window of the above structure, by unlocking both handles, the engagement of the penetrating shafts of both handles is automatically released, and it is possible to swing the outer shoji simply by unlocking the handles for fixing the inner and outer shoji. This is the result.

〔Example〕

This invention will be explained below based on the drawings.

Figure 1 is a front view showing an example of the revolving window of this invention, and Figure 2 is a sectional view taken along the line - in Figure 1.
The case of a horizontal axis rotating window is shown. This revolving window includes an inner sash 3 fitted in a window frame 1 and rotatably supported by a rotating shaft 2, and an inner sash 3 that swings at one end in a direction orthogonal to the rotational axis of the inner sash 3, that is, at the lower end. It consists of an outer shoji 4 that is movably supported, and handles 5, 5 for fixing the inner and outer shoji are attached to the free end side of the outer shoji 4.

As shown in FIGS. 3 and 4, the support portions of the inner shoji 3 and the outer shoji 4 extend from both shojis 3 and 4 toward the other shoji, respectively. It is composed of penetrating shafts 8, 9 of the inner and outer handles 6, 7, and in this case, one of the penetrating shafts, for example, the penetrating shaft 9 of the outer handle 7, has a U-shaped cross section as shown in FIG. An engagement recess 10 is provided, and a square shaft portion 11 as shown in FIG. 6 is provided on the other side, that is, the penetrating shaft 8 of the internal handle 6, so that the engagement recess 10 and the square shaft portion 11 can be engaged and disengaged. It is made by fitting into. The manner in which the two through shafts 8 and 9 are engaged and disengaged is as shown in FIG.
For example, by rotating one of 7 by 135 degrees,
The opening of the engagement recess 10 is located on the swinging side of the outer shoji 4, and the square shaft portion 11 is separated from the engagement recess 10 so that the outer shoji 4 can swing. In the above description, the outer shoji 4 swings when the through shafts 8 and 9 rotate by 135 degrees, but it goes without saying that the rotation angle can be set arbitrarily.

Note that 12 is a blind installed between the inner and outer shoji 3 and 4, and is equipped with an extendable and retractable mechanism (not shown) so as to block light as necessary. Also 13
is a locking pinion attached to the penetrating shaft 8 of the internal handle 6, which meshes with a rack (not shown) inserted into the frame of the inner shoji 3, and connects the locking pin attached to the rack with the window frame side. A receiving metal fitting attached to the shoji 3 is engaged with the shoji 3 so that the shoji 3 can be locked. Note that this operation is such that all four circumferential surfaces of the shoji 3 are locked with one handle.

The rotating window of this invention configured as above is
By rotating and unlocking the handles 6 or 7, the engagement of the through shafts 8 and 9 of both handles 6 and 7 is automatically released, so simply releasing the locks of the handles 5 and 5 for fixing the inner and outer shoji The swinging operation of the outer shoji 4 becomes possible, and cleaning of the glass inner surfaces of the inner and outer shoji 3, 4 and the blind 12, as well as maintenance and inspection of the blind 12, can be easily performed.

After cleaning etc. are completed, when the outer shoji 4 is returned to its original position, the through shafts 8 and 9 of the inner and outer handles 6 and 7 are automatically engaged, allowing normal opening and closing operations. The external handle 7 is used for emergency intrusion, such as entering a building from the outside for rescue purposes in the event of a fire, and can be easily unlocked and opened by rotating the external handle 7 from the outside. It can be opened.

Although the above embodiment describes a horizontal axis type rotating window, similar effects can be obtained with a vertical axis type rotating window.

[Effect of idea]

As explained above, according to the revolving window of this invention, it is possible to easily clean between the inside and outside shojis, or to maintain and inspect the blinds installed between the shojis, and in case of an emergency such as a fire, the outside Since excellent effects such as being able to make emergency intrusion possible by operating the handle are achieved, its utility value is remarkable.
