Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to vertical blinds such as Venetian blinds and winding blinds.

[0002]

[Prior art]

 Conventionally, vertical open / close blinds can be said to be louvers or curtains that hang in a blind shape over the entire inside surface of a window.A head box with an opening / closing mechanism is installed at the upper end, and the operation cord hangs from it. Or, when the operating rod was handled, the hanging curtain went up, opening from below so that light could enter.

Among the vertically openable blinds, a winding blind is a curtain in which the fabric is specially processed (stiffener process) with resin or the like, and the window is simply opened and closed by moving it up and down. The chamber blind is a parallel structure of slats (blades) that are long thin plates next to an aluminum alloy whose curtain is acrylic resin baked, and is an open / close louver type in which the slats are connected in parallel and the angle can be adjusted with a string. Therefore, it is possible not only to open and close the curtain, but also to adjust the amount of incident light that passes through the curtain by changing the slat angle.

[0004]

[Problems to be solved by the device]

 In any case, conventional vertical blinds can open and close the window from below or at a free height, so the amount of incident light can be adjusted and the light can be blocked. In order to open in order, the following problems occur in that, for example, when half-opening, the lower half always opens.

1) The sunshine position in a room is determined by the position of the sun and the open position of the vertically openable blinds, and is limited to the window side. It lacked the freedom that it was impossible.

2) The blind is originally installed for the purpose of blocking or adjusting the sun's light and for the purpose of preventing the inconvenience of others seeing into the room. However, when the blind is opened halfway, There is an inconvenience that the state of the room is always visible.

3) Furthermore, it is expected that the outside environment will not be seen and the static environment of the room will be visually maintained. However, this is also the case when the blinds are opened halfway. Since it is at eye level, the outside condition can be seen and the so-called blindfold function disappears.

In view of the above situation, the present invention provides a vertical opening-and-closing type blind not only capable of full opening and closing and lower half opening, but also upper half opening if necessary, as in the conventional case. Aimed to provide.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a vertical open / close blind according to the present invention includes an upper half blind that closes the upper half of the window as a curtain and a lower half blind that closes the lower half inside and outside the window. The feature is that they are installed in parallel and can be opened and closed independently.

If at least one of the upper half blind and the lower half blind is a Venetian blind, the opening and closing modes will be further varied.

[0011]

[Action]

 Since the vertical open / close blind is constructed as described above, it is in a fully closed state at a predetermined closed position between the upper half blind and the lower half blind, and is fully opened at both pulled up positions. It becomes a state.

However, when only the lower half blind is closed by the predetermined lower half, only the upper half is opened. This will allow sunlight to enter from only the upper half.

[0013]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

The drawing shows an example implemented as a ventilator blind, and the vertical open / close blind hangs an upper half blind 1 and a lower half blind 2 inside a window W, A head box 3 with an opening / closing mechanism is attached to the upper end.

Inner and outer glass screens 5 and 5 are fitted into the window W, and the upper half blind 1 is located inside and the lower half blind 2 is located inside thereof, but the reverse is true. May be. The type of the window W is not limited to the flat window of the opening / closing door, and may be, for example, a bay window or a dead-end window.

The blinds 1 and 2 have a large number of laterally formed slats 7, 7, ... Connected vertically by a pair of inner and outer angle slings 9, 9 that open and close at an angle. Further, in the middle of each slat 7, 7, ..., A vertical hanging string 11 that opens and closes vertically as a curtain is passed, and the angle hanging strings 9 and 9 and the vertical hanging string 11 are attached to the lower bar 13 at the lower end. It is connected to 15. This point is similar to the conventional Venetian blind, but in the lower half blind 2, the slats 7 are not provided in the upper half of the window W between the angle slings 9, 9 and the vertical slings 11. I am excluding.

On the indoor side, an operation code 17 of the upper half blind 1 and an operation code 19 of the lower half blind 2 hang down, respectively, and adjust the angle of the slat 7 independently and as a curtain. It is opened and closed. This opening / closing mechanism is the same as the conventional one, but it is convenient if it is possible to open / close both the blinds 1 and 2 by one operation code by improvement.

Next, a mode of opening and closing will be described with reference to FIGS. In the figure, the chain double-dashed line indicates the closed state of the slats 7.

In the case of FIG. 2, the upper half blind 1 and the lower half blind 2 each show a closed state as a curtain, and as shown by the solid line, the slat 7 is opened. When there is, the incident light to the room is relaxed. This is a state in which the inside cannot be seen from the outside, but the outside can be seen from the inside.

In this case, by opening and closing the slats 7 differently in the upper half blind 1 and the lower half blind 2, an unprecedented mode is obtained. For example, the slats 7 may be opened in the upper half blind 1 and closed in the lower half blind 2. As described above, various aspects can be generated based on the case of FIG.

In the case of FIG. 3, the upper half blind 1 is opened as a curtain and the lower half blind 2 is closed. In this way, the sun light can enter only from above the window W, and the light incident on the window can be blocked. In other words, the sun's rays can enter only relatively far inside the room. In this case, the lower half blind 2 can also be adjusted in the angle of the slat 7 to obtain a delicate mode that has not been obtained in the past.

In addition to the embodiment of FIG. 3, in particular, since the upper half of the window W allows sunlight to enter from the upper half of the window W, at the height where the occupants are present, heat insulation and noise prevention are achieved. , Comfortable space can be obtained in the room in winter. In addition, since it is possible to block the light incident on the window, there is no inconvenience in placing a child's study desk in the south window, which was conventionally unsuitable.

In FIG. 4, both the upper half blind 1 and the lower half blind 2 are opened as curtains. That is, it is the entire state of the window W.

In FIG. 5, the lower half blind 2 is fully opened as a curtain, and the upper half blind 1 is closed as a curtain. Therefore, direct sunlight enters only from the lower half of the window W.

Among the above, in relation to the aspect shown in FIG. 3, the upper half blind 1 can be made to descend to the lower half (see the alternate long and short dash line in the same figure). Then, the lower half of the window W will be double-closed, and the sunlight, cold air, and noise from the lower half will be reliably blocked.

[0026]

[Effect of device]

 As described above, the present invention has the following excellent effects.

For the incident light of the sun, the irradiation is not limited to the window, and the upper half blind is raised and opened, and only the lower half blind is closed at that position, thereby avoiding the window. Since the sunlight can be inserted into the back of the room, for example, it is possible to place a child's study desk in the south window without any inconvenience, and a bed for a sick person or a bedridden old person can be placed healthy by the window. By closing only the lower half of the window, it is possible not only to prevent peeping from the outside, but also to prevent stress from outside the window in a healthy state where the sun's rays are taken into the room. You can get a quiet and calm indoor environment without noticing.

When it is a Venetian blind (Claim 2), since the modes of opening and closing become more diverse, the above-mentioned various effects become remarkable.
