Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a rotating window open confirmation device for knowing the outdoor wind condition before opening the rotating window.

[Conventional technology and its problems]

The rotating window requires a shaft that rotatably supports the shoji,
Among them, the side-opening window has a weak support structure because this shaft also moves in the expected direction. Therefore, if you open the window to the outside inadvertently under strong wind, the shoji will be agitated by the wind, and in the worst case, the shaft supporting the shoji will come off the upper and lower rails, and there is a risk that the shoji will fall and the operator will fall. is there. In addition, gusts may enter the room and scatter documents and the like in the room.

In general houses, we experience the danger of seeing the swaying of vegetation through the window, but in a residential area, there is no clue to the presence or absence of wind like vegetation. There is a high possibility of falling into the above danger.

Therefore, an object of the present invention is to provide an opening confirmation device for a rotating window that can avoid the above danger.

[Means for solving problems]

In order to achieve the above object, the present invention provides a rotary window opening confirmation device, characterized in that a conduit for communicating with an overseas is provided in a frame or a frame of a rotary window, and a wind force detecting means is provided at an indoor end of the conduit. It is in.

The conduit may be installed on either the window frame or the shoji frame. However, the indoor end of the conduit should be at eye level where the operator stands.
It is desirable to make the wind force detection means easy to see during the opening operation.

Although the wind turbine is simply shown in the embodiment as the wind force detecting means, the present invention is not limited to this, and any means capable of visually checking the presence or absence of wind may be used. It should be noted that two conduits may be provided so that air does not enter the room.

[Action]

When the rotating window is opened, it is possible to know the outdoor condition, in particular, whether strong wind is blowing or not, by the wind force detecting means, so that it is possible to prevent the sliding door from falling off and the operator from falling.

〔Example〕

 Hereinafter, embodiments will be described with reference to the drawings.

The embodiment is intended for the sliding window 1 shown in FIG. The outline of the side opening window 1 will be described with reference to this drawing. The shoji 3 built in the window frame 2 is provided with upper and lower frames 2A, which are attached to the upper and lower ends of the right frame 3D.
It moves in the find direction along the upper and lower rails laid on 2B, and further rotates about the rotation axis provided in the upper and lower slide fittings so that the left frame 3C rotates outward. This rotation is limited by a pair of arms connecting the upper and lower frames 2A and 2B and the upper and lower frames 3A and 3B, and the opening of the shoji 3 is determined by the positions of these arms. The operation is performed by the Gremont handle 4 attached to the left frame 3C.

If you accidentally open the shoji 3 in the strong wind by grasping the glemon handle 4, the hand holding the gremon handle 4 will be dragged outside when the shoji 3 is swung by the wind and suddenly opens, and at the same time, you will be physically tired. It is very dangerous. Also, since the support structure cannot be said to be strong, in the worst case, the vertical sliding metal fittings will separate from the vertical rails and the shoji 3 will fall, which may be harmful to passers-by under the building. Will be extended.

The present invention is designed to avoid the above danger, and the open confirmation device 5 for confirming the safety is provided on the left frame 3C.
In particular, the upper part of the Gremon handle 4 is selected and attached. This position has the advantage of attracting attention because it is easy to enter the operator's visual field when performing the opening operation. The detailed structure of the opening confirmation device 5 is shown in FIG.

In detail, referring to FIG. 1, a left conduit 3C is provided with one conduit 6 communicating with the inside and outside. This conduit 6 guides a part of the outdoor wind to the indoor side so that the strength of the wind blown outdoors can be known also to the indoor side. Of course, the material and the shape are not critical, and it may be formed in a hollow shape using a corrosion-resistant metal such as aluminum, a synthetic resin, a flexible rubber or the like. In the illustrated example, the conduit 6 is formed in a cylindrical shape, and the conduit 6 is bent and arranged so that steps are formed at the indoor and outdoor ends 6a and 6b in the left frame 3C. The step difference is such that the outdoor end 6b is lower than the indoor end 6a. This is designed to prevent rain, and even if rainwater may enter from the outdoor end 6b, the rainwater does not cross the step and enter the indoor side.

On the other hand, the indoor end 6a is provided with a wind force detecting means 7 that allows the indoor side to know the strength of the wind blown outdoors. Wind power detection means include, for example, mechanical detection means using a wind turbine and detection means using heat rays, but electrical detection means requires a power source, so it is desirable to use mechanical detection means if possible. Good In the embodiment, a wind turbine 7 having a simple structure is used. Although not shown, the wind turbine 7 is supported by bearings near the indoor end 6a.

The wind turbine 7 is protected by an indoor cap 8, and a transparent glass or plastic 9 is fitted on the top of the cap 8 so that the wind turbine 7 can be seen from the indoor side.
When the inner end 6a of the conduit 6 is closed by the cap 8, air does not enter the conduit 6, so that the glass or plastic 9 is provided with a plurality of through holes 9a. Since processing is troublesome in the case of glass, a through hole may be provided on the cap 8 side.

On the other hand, the outdoor end 6b is directed straight to the outside, but the side opening window 1 targeted by the embodiment is such that the left frame 3C is rotated outward and is weak against the wind blown from the left. The left wind may be detected with the outdoor end 6b facing left.

As shown in FIG. 2, an insect repellent cap 10 is attached to the outdoor end 6b. This cap 10 has a net 11 stretched on the front surface to prevent invasion of mosquitoes and the like.

In the above embodiment, when the wind is blowing outdoors, especially outside the sliding window 1, a part of the wind enters the room side through the conduit 6 and turns the windmill 7 attached to the room end 6a. The strength of the wind blown outdoors can be known from the condition of the windmill 7. The opening time can be determined without opening the shoji screen 3. However, since subjective factors are probably involved in determining the degree of turning, the windmill 7 may be prevented from turning without a predetermined wind force to notify a dangerous state. This can be easily performed by applying a thrust force that opposes the wind force to the bearing that supports the wind turbine 7 via a spring or the like.

The above is an example of one conduit, but it is also possible to use two conduits as shown in FIG. 3 to prevent wind from entering the indoor side. In this embodiment, the glass or plastic 9 of the indoor cap 8 is not provided with a through hole, and two conduits 12,
It is designed to return to the wind and the outside by using 13 and two conduits 12 and 13 are oriented such that their outdoor ends 12b and 13b are orthogonal to each other. Therefore, if the wind blows outdoors, dynamic pressure will act on one of the outdoor ends and static pressure will act on the other outdoor end, resulting in a differential pressure between the two conduits. The wind enters the indoor side through one conduit, turns the windmill, and then returns to the outdoor side through the other conduit. Since the differential pressure increases as the wind speed increases, the way the windmill rotates is proportional to the differential pressure, and it is possible to know the wind strength outdoors while staying indoors. The wind turbine 8 attached to the indoor end 12a of the one conduit 12 may be attached to the indoor end 13a of the other conduit 13.

Although the above-mentioned embodiment is intended for a side-opening window, it is also applied to other rotary windows such as a horizontal axis rotary window and a vertical axis rotary window in order to ensure safety.

[Effect of device]

As described above, according to the present invention, it is possible to know the outdoor wind condition in advance during the opening operation, so that it is possible to prevent the sliding door from falling off and the operator from falling.
