Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a retractable skylight mounted on a pitched roof.

[0002]

[Prior art]

 Conventional open-and-close type skylights have an opening part in the roof in the middle of the sloped surface of the sloped roof, and a skylight unit with a glass plate that can be opened and closed is attached to the opening part of the frame projecting upward. An opening / closing mechanism including a motor, a transmission unit, and a motion conversion unit is provided inside the frame body, and the motor is rotated in the forward direction or the reverse direction by the opening side operation or the closing side operation of the switch, and the rotational movement is caused by the glass. It is configured to open or close the skylight by converting it into a rotational movement of the plate.

[0003]

[Technical problems to be solved]

 Because of the above-mentioned configuration, first, the skylight unit obviously protrudes from the roof surface, impairing the roof appearance. Secondly, since the opening / closing mechanism is mounted inside the frame, the installation position is difficult and it does not fit well, and it is exposed to the optical path of the skylight, which causes a problem that the lighting efficiency also decreases.

Furthermore, the attic temperature in summer becomes considerably high, and the hotter the air rises to the top of the attic, but the conventional skylight is installed in the middle of the pitched roof, so even if the skylight is opened, high temperature air will be left in the attic. In the night, the heat dissipation performance of the building was not good, and at night, the room temperature of the room especially near the roof was kept at high temperature due to the conductive heat, which caused sleepiness and increased cooling load.

In view of the above points, the present invention has a high lighting rate and a good attic ventilation efficiency when opened, thus improving the heat dissipation performance of the building and easily installing the opening / closing drive mechanism. The purpose is to provide a retractable skylight with a good opening.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the retractable skylight according to the present invention is provided with a ridge box having a required length in the ridge of a pitched roof, and an opening frame having an upper side adjacent to the bottom side of the ridge box. It is equipped with a sliding door that is attached to the roof surface and moves along the slope of the roof to open and close the opening surface of the opening frame, and a drive mechanism that opens and closes the sliding door is housed in the ridge box. It is characterized by being. Further, the ridge box also serves as a wrapping with a ventilation hole, and the ridge box is characterized by containing a forced ventilation means for ventilating between the attic and the outside through the ventilation hole.

[0007]

[Action]

 When the drive mechanism is driven via the open / close switch, the sliding door in the opening frame is moved along the sloped roof surface to open / close the opening. Since the upper side of the opening frame is installed adjacent to the lower side of the building box, and the sliding door is attached to the opening frame so that it can be opened and closed, the attic can be opened and closed at the top. If the wing box also serves as a wrapping box that has a ventilation function, and if the wing box is equipped with forced ventilation means, it is possible to ventilate in the ridge even when the skylight is closed.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a roof having an openable skylight according to an embodiment, FIG. 2 is a plan view of the skylight portion, FIG. 3 is a sectional view taken along line XX of FIG. 2, and FIG. 4 is Y- of FIG. It is a Y sectional view.

The skylight according to the present invention comprises a ridge box 1, an opening frame 2, a sliding door 3 and a drive mechanism 4.

The ridge box 1 is mounted on the ridge portion 5 of the sloping roof R, or in place of the ridge portion, on the roof top portion, and the motor 41 constituting the drive mechanism 4 therein and one end of the motor rotation. A rotary shaft 43 coupled to the shaft, the other end of which is supported by a bearing 42 provided inside the other end of the ridge box; and a wire winding cylinder 44 fixed on the rotary shaft near both ends thereof. Is equipped with.

The opening frame 2 is formed by connecting a long frame material in a rectangular shape, is inclined downward from the mounting position of the ridge box 1 along the slope of the slope roof, and has the upper side of the frame. It is attached to the roof surface in a state of being close to the lower side of the building box 1. A concave groove (not shown) is formed on the upper side of the opening frame 2 so as to open toward the lower side, and a guide groove 21 is formed on the facing surface of the left and right frame members as shown in FIG. In the opening frame 2, there are provided doors 31 and 32 in which at least two glasses are attached to the guide groove 21. In the illustrated example, the guide grooves 21 are provided in upper and lower two steps, and a door 31 that shields the lower half of the opening frame is attached to the lower guide groove 21 by fitting it, and the upper guide groove 21 is also attached. The sliding door 32 is mounted so as to be movable from the upper half to the lower half of the opening surface of the opening frame 2. In the illustrated example, when the sliding door 32 is moved to the lower half, the opening surface of the upper half of the opening frame 2 is opened. Further, in order to enable smooth movement of the sliding door 32, rollers 33 protruding from the upper surface and the lower surface of the sliding door 32 are provided on the left and right sides of the sliding door vertically separated from each other along the roof slope. The upper and lower surfaces of the guide groove 21 are in contact with each other.

Further, the other ends of the wires 45 wound around the wire winding drum 44 provided on the rotation shaft inside the both ends of the ridge box are coupled to the upper portions on the left and right sides of the sliding door 32. A lower limit sensor and an upper limit sensor (both not shown) that operate and output when the sliding door 32 is moved downward or upward are provided, and the outputs of these sensors are output from the control circuit of the motor 41 (see FIG. (Not shown).

Then, when an open / close switch (not shown) provided at an appropriate position indoors is operated to the open side, the motor control circuit causes the motor to normally rotate, and the transmission means (the rotating shaft 43, the winding drum). When the sliding door 32 moves downward via the cable 44 and the wire 45 to open the skylight and is opened to the lower limit position overlapping the lower door 31, the lower limit sensor operates and the motor 41 is stopped.

When the open / close switch is operated to the closing side, the motor control circuit causes the motor to rotate in the reverse direction, and the sliding door 32 is moved upward through the transmission means to reach the upper limit position for closing the skylight. Operates to stop the motor. Since the upper side of the opening frame 2 is located below the building box 1, when the sliding door is opened, the top of the attic is communicated to the outside, and when the sliding door is closed, the opening frame and the sliding door are closed. Since the upper side is located below the building box, a large lighting area can be secured.

As described above, and as shown in the figure, in this skylight, the opening frame is provided along the roof slope, and the sliding door is also provided so as to be moved along the roof slope. Since it does not project from the roof surface in either open or closed state, the open / close skylight does not impair the appearance of the roof, and since it does not receive wind pressure during opening, it is highly safe. In addition, there is no fear of snow accumulating around the skylight mounting part when snowing as in the conventional case.

The structure of the opening / closing drive mechanism of the sliding door is merely an example, and the installation position of the motor is not limited as long as it is inside the ridge box, and the transmission mechanism is replaced by the motor instead of the rotary shaft and the wire. It may be constituted by a gear to be rotated, a screw rod, and a female screw body attached to the sliding door and meshed with the screw rod.

Further, although the illustrated embodiment is a preferred mode in which skylights are formed on both sides of the ridge, it goes without saying that it may be provided only on one side of the ridge.

Since the building box 1 is provided at the top of the building, ventilation holes are appropriately provided in this building box, and forced ventilation means such as a fan motor is installed in this building box to prevent the skylight from opening or opening. In unfavorable weather conditions, the forced ventilation means can be operated to remove the hot air in the attic to the outside, creating a comfortable indoor environment.

[0019]

[Effect of device]

 As described above, according to the present invention, since the skylight is installed close to the ridge, and the drive mechanism is housed in the ridge box, and the storage is good, the lighting rate is high and the attic ventilation when opened is high. Efficient, thus improving the heat dissipation performance of the building, and easy to install the drive mechanism.
