Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening/closing device for a daylighting skylight which can be opened and closed by electric operation and manual operation.

While skylights let in sunlight, they also need to ventilate during normal use or exhaust smoke during emergencies, so skylights that can be opened and closed are increasingly being installed. Most opening/closing mechanisms are operated manually, so
When a large number of skylights for daylighting are installed in a factory or the like, it takes a lot of time and effort to close them.
Recently, there has been a trend to increase the weight of skylights, such as increasing the size of skylights and using wired glass in order to improve lighting efficiency, and the load required to open and close them has increased. His appearance was strongly desired.

The present invention was made in view of this situation, and its gist is that a skylight is pivotally attached to an opening frame, and is attached so that elastic force in the opening direction is imparted to the skylight. In the opening/closing device of a skylight for daylighting, an electric hoist is installed inside the open side or at an appropriate location in the room, and a manual hoist is also installed, and one end of the rope attached through the skylight is hoisted up using an electric hoist. There is provided an opening/closing device for a daylighting skylight, characterized in that the opening/closing device is interlocked with a manual hoisting machine and the other end is interlocked with a manual hoisting machine.

The present invention will be explained in more detail below with reference to drawings of embodiments.

FIG. 1 is a perspective view of an opening/closing device according to an embodiment of the present invention in a closed state, FIG. 2 is a perspective view of the same in an open state, and FIG. 3 is a perspective view of an electric hoist. In the figure, reference numeral 1 denotes an opening frame made of steel that is attached to an opening A of a building, and is connected to the opening A of the building by an anchor fitting (not shown). 2 is a skylight,
Methacrylic resin, polycarbonate resin or
It consists of a skylight main body 21 made of FRP or the like, and a surrounding frame 22 surrounding the skylight main body 21 on all four sides. Reference numeral 3 denotes a hinge that connects the opening frame 1 and the surrounding frame 22. Further, in FIG. 2, 4 is an arm consisting of a main arm 41 and a sub-arm 42, 5 is a torsion bar spring consisting of two pieces that provides elastic force in the opening direction to this arm 4, and 51 is this arm. It's a cover.

In such an opening/closing device, the present invention includes an electric hoisting device 6 installed at an appropriate position inside the open side or inside the room, that is, inside the opening frame 1 in the illustrated example. The electric winding machine 6 in this example employs a reversible electric motor, and a worm gear (not shown) is built into the gear box 63 to enable forward and reverse rotation and stop during painting. . In such an opening/closing device, the rope 7 is attached through two pulleys 24, 24 fixed to the open end of the surrounding frame 22, one end of which is linked to the electric hoist 6, and the other end is connected to the manual hoist. It is linked to 9. This manual winding machine 9 consists of an operation box 91 and a rotary handle 92, and although not shown, the operation box 91 houses a winding drum and an opening/closing mechanism with a damper. In addition, 93 in the figure is an embedded conduit for guiding the rope 7.

To explain the opening/closing operation in this example,
First, there are two methods for opening.
When using the electric hoisting machine 6, first press the open button on the operation board 64 to rotate the motor 61 in the reverse direction and let out the rope 7 wound around the pulley 62. In this case, the other end of the rope 7 is fixed to the manual hoist 9, so the rope 7 is let out in the direction of the manual hoist 9 via the two pulleys 24, and the skylight 2 is moved by the torsion bar spring 5. Opened by force. In this example, an opening/closing position control mechanism 8 including an upper limit switch 81 and a lower limit switch 82 is provided. It's in control. In addition, when using the manual winding machine 9, when the push button for releasing the damper-equipped opening/closing mechanism in the operation box 91 is pressed, the pawl of the damper-equipped opening/closing mechanism is unlocked and the winding is carried out on the winding drum. The rope 7 is let out, and the skylight 2 is opened by the elastic force of the torsion bar spring 5, as in the case described above. When opening using the manual hoisting device 9 in this manner, it can be operated even during a power outage, and is particularly convenient for opening in an emergency such as a fire. On the other hand, to close using the electric hoisting machine 6, press the close button on the operation board 64, and the rope 7 will be hoisted up by the pulley 62, resisting the elastic force of the torsion bar spring 5. Then, the skylight 2 is lowered to a position where the lower limit switch 82 is activated, and the skylight 2 is closed. When using the manual hoisting machine 9, the hoisting drum in the operation box 91 is rotated by the rotary handle 92, and the rope 7 is hoisted against the elasticity of the torsion bar spring 5. is closed. Therefore, in this case as well, operation can be performed during a power outage. In this invention, the opening/closing operation by the electric winding machine 6 and the manual winding machine 9 can be used depending on the purpose, but in this example, opening/closing of a daylighting skylight equipped with an existing manual winding machine is possible. It has the advantage that the device can be easily equipped.

Although the present invention has been described above based on the illustrated embodiment, the present invention is not limited to such an example. For example, in order to impart elastic force to the skylight 2, the torsion bar spring 5 may be replaced A general coil spring can be used for the electric hoisting device 6, and it is also possible to replace the electric hoisting device 6 with one of other construction, or change the installation location to a wall surface of the room or the like.

Since the present invention has the configuration as described in detail above, it is possible to easily open and close a daylighting skylight by electric operation, and the structure is simple and easy to install. It has the advantage that it is easy to apply, and that it can be opened and closed according to the purpose by using both electric and manual operation.
