Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a skylight in which an opening/closing window is provided in an atrium formed in a roof or the like.

(Prior Art and Problems) Conventionally, a skylight has been provided in an atrium formed on a roof or the like for the purpose of letting light into the room. As shown in FIGS. 5 and 6, these skylights are constructed by screwing an opening/closing window 4 having a lighting section 3 at one end into an atrium 2 formed on a roof 1 or the like so that it can be opened and closed. It is also possible to ventilate smoke in case of emergency such as ventilation or fire.

However, since a horizontal surface 3a exists on the indoor side of the lighting section 3 provided in the opening/closing window 4, condensed water forms on the inside of the horizontal surface 3a when there is a large difference between the outside temperature and the indoor temperature such as in winter. However, there was a problem that this condensed water would fall into the room. Furthermore, in cold regions, there is a problem in that condensed water that collects at the contact area between the lower edge of the opening and closing window and the upper surface of the draining part formed around the four circumferences of the frame freezes, making it impossible to open and close the window.

(Purpose of the invention) The present invention was made in view of the above points,
To provide a skylight that prevents generated dew water from falling into a room and prevents it from becoming impossible to open and close due to freezing.

(Structure of the invention) In the present invention, an opening/closing window that covers an opening formed surrounded by the frame is screwed onto the top surface of a frame that is installed on a mounting base and has draining parts expanded on the outer side of the four peripheries. In the skylight installed, the inner surface of the opening/closing window is inclined toward one end, and a water tray is disposed below the lower end thereof, and a heater is provided in the draining part and the water tray. It is characterized by being

(Example) The present invention will be described in detail below based on an example shown in the drawings.

1 to 4 show an embodiment of the present invention, in which a plurality of mounting stands 5 integrally formed in a rectangular frame shape and made of concrete are stacked on top of a roof 1 surrounding an atrium 2. A frame body 7 with draining portions 6 extending in all directions is fixed to the upper part thereof, and an opening 8 surrounded by the frame body 7 is formed in the upper surface 7a of this frame body 7. An opening/closing window 9 that covers the opening/closing window 9 is screwed at one end. The opening/closing window 9 has a flat quadrangular truncated pyramid shape with an inclined upper end surface 10, and the upper end surface 10 is inclined toward one end.
A lighting member 12 made of a glass plate with a wire mesh is fitted into an opening 11 formed in the opening 11, and a light shielding device 15 having a light shielding sheet 14 wrapped therein is provided on the inner side 13. . Both ends of the tip 14a of this light shielding sheet 14 are connected to the lighting device 1.
The light shielding sheet 14 is fitted into a pair of grooves 16 adjacent to the inner surface 12a of the lighting member 12, and both ends of the tip 14a slide within the grooves 16, so that the light shielding sheet 14 is fitted along the inner surface 12a of the lighting member 12. Move the light to adjust the light. A water tray 17 is installed on the upper surface 7a of the frame 7 below the lower end of the lighting member 12, which is inclined to become lower toward one end of the opening/closing window 9, that is, toward the side opposite to the hinged portion. A heater 18 is provided at the bottom of this water tray 17. Further, inside the frame body 7, the heater 18 is located on the lower surface of the draining section 6 which is expanded in all directions.
A heater 19 is provided which is continuous with the heater 19. In addition,
20 and 21 are gaskets for preventing rainwater etc. from entering the room when the opening/closing window 9 is closed;
Further, 22 is a spring for opening the opening/closing window 9, and 23 is a buffer consisting of a buffer or a damper for controlling the opening speed and stably opening operation. Furthermore, 24 is an electric motor that controls the opening and closing of the opening/closing window 9 by winding one end 26a of the cable 25 wound around a rolling pulley 25 provided on the upper surface 7a of the frame 7 and the inner side 13 of the opening/closing window 9. It is a winding machine, and its start and stop switches are installed indoors, and the other end 26b of the cable 26 is wound on a manual winding machine (not shown) that is also installed indoors, and these winding machines When either the other end 26a or 26b of the cable 26 is released, the opening/closing window 9 is opened by the action of the spring 22 and the buffer 23, and when the cable is wound again, the window 9 is closed.
In addition, if you want to adjust the lighting, you can use the light shielding sheet 14.
It is sufficient to let out or feed in along the groove 16 using electric power or manual force. In particular, in this embodiment, since the light shielding device 15 wrapped with the light shielding sheet 14 is provided on the opening/closing window 9, the light shielding sheet 15 rotates together with the opening/closing window 9 to expose the opening 8.
Ventilation or smoke can be removed regardless of the amount of cable 26 that is fed out. Therefore, in the event of an emergency such as a fire, all that is required is to operate the release button on the manual winder installed in the room and let out the cable 26 all at once. Can be opened and smoke removed.

When the skylight of the present invention is installed, if there is a significant difference between the outside temperature and the indoor temperature such as in winter, condensation water 27 may occur inside the lighting member 12. The condensed water 25
The water travels through the lighting member 12 to the lower end, falls and is collected in a water tray 17 provided below this end, where it is heated and evaporated by a heater 18 provided below. do. Furthermore, water from the outside such as rain flows along the upper end surface 10 of the operable window 9 through the draining part 6 to the roof 1, and in particular, in this embodiment, the water from the outside flows into the contact area between the operable window 9 and the frame 7. is Patsukin 2
0 and 21, so there is no need to worry about it leaking into the room.

(Effects of the invention) The present invention provides a skylight in which an opening/closing window is hinged to the upper surface of a frame installed on a mounting base to cover an opening formed by the frame, and the inner surface of the opening/closing window is Because the structure is tilted toward one end, even if condensation occurs on the inner surface of the opening/closing window, the condensed water will flow down the inner surface and fall into the room through the opening. There is no. In addition, since a water tray is provided below the lower end of the inner surface of the opening/closing window, condensed water collects in this water tray.
The condensed water that has accumulated in the water tray is evaporated by the heater provided in the water tray. Furthermore, since a heater is installed inside the drainer, it is possible to prevent the contact area between the opening/closing window and the top surface of the frame from freezing in cold regions, making it impossible to open/close the opening/closing window. can.
