Description

TECHNICAL FIELD The present invention relates to a skylight device used for obtaining light and ventilation from a roof.

BACKGROUND ART A skylight device is formed by including a window frame 1 attached to an opening portion of a roof, and a skylight 2 having a rear end portion pivotally attached to the window frame 1 so as to be vertically rotatable. There is such a skylight device in which a gas spring 3 is attached between a side end portion of the skylight 2 and the window frame 1 so that the gas spring 3 opens the skylight 2. The gas spring 3 is formed by including a cylinder 7 in which air is sealed and a rod 8 attached to the cylinder 7 in a state of being urged by the air pressure of the sealed air in a protruding direction. The skylight 2 can be opened by rotating the skylight 2 upward by the elastic force protruding from the cylinder 7.

However, when the gas spring 3 is used as described above, the fourth
As shown in the figure, in the initial state when the skylight 2 is opened, the direction of elastic force of the gas spring 3 (arrow b) is substantially perpendicular to the direction of rotation of the skylight 2 (arrow a). The elastic force of the gas spring 3 does not effectively act as a force for rotating the skylight 2 upward, and there is a problem that the skylight 2 cannot be smoothly opened.

[Object of the Invention] The present invention has been made in view of the above points, and an object thereof is to provide a skylight device capable of smoothly rotating and opening the skylight.

DISCLOSURE OF THE INVENTION In the skylight device according to the present invention, however, the rear end of the skylight 2 is pivotally attached to the window frame 1 so as to be vertically rotatable, and the skylight 2 is attached to the upper side of the window frame 1 so as to be openable and closable. One end of the spring 3 is the skylight 2
The other end is attached to the window frame 1 at the side end of the window spring 1 to urge the skylight 2 in the opening direction by the elastic force of the gas spring 3, and the leaf spring 4 is provided between the window frame 1 and the skylight 2. Leaf spring 4
It is characterized in that the skylight 2 is biased in the opening direction by the elastic force of the leaf spring 4, and when the skylight 2 is initially rotated, it is assisted by the leaf spring 4 in which the elastic force particularly effectively acts. The skylight 2 can be smoothly rotated upward, and the present invention will be described in detail below with reference to embodiments.

The window frame 1 is formed in a rectangular frame shape as shown in FIG. 2, and is attached on the draining plate 9 at the opening of the roof. The skylight 2 is formed by attaching a glass plate 11 to the inner periphery of the frame body 10, and the rear end portion is pivotally attached to the rear end portion of the window frame 1 by a hinge 12 or the like so as to be vertically rotatable. As a result, the skylight 2 is attached to the upper side of the window frame 1 so as to be openable and closable. The gas spring 3 is formed of a cylinder 7 in which air is sealed and a rod 8 attached to the cylinder 7 in a state of being urged by compressed air pressure of the sealed air in a protruding direction. 2 are respectively arranged at both ends of the cylinder 7. As shown in FIG. 3, for example, the tip of the rod 8 is vertically rotatably connected to the frame body 10 of the skylight 2 by a connecting tool 13 and the cylinder 7 is connected. A base end is vertically rotatably coupled to the window frame 1 by a connecting tool 14, and a gas spring 3 is attached between the skylight 2 and a side end portion of the window frame 1. Since the rod 8 is biased in the direction of projecting from the cylinder 7, the gas spring 3 exerts a biasing force to rotate the skylight 2 upward. Also,
A leaf spring 4 is attached between the side end of the window frame 1 and the side end of the skylight 2 at the rear position of the gas spring 3. The leaf spring 4 is formed by bending a spring steel plate into a substantially horizontal U shape, and is attached by connecting both ends thereof to the window frame 1 and the skylight 2. Therefore, the leaf spring 4 applies a biasing force to the skylight 2 to rotate it upward. It should be noted that both the gas spring 3 and the leaf spring 4 are hidden by the upper surface side of the window frame 1 and cannot be seen from the lower room, and there is no fear of impairing the appearance.

An engaging member 15 formed of a hook or the like is provided at the tip of the skylight 2. By engaging this engaging member 15 with the window frame 1, the opening of the window frame 1 is closed by the skylight 2. I try to keep it. Then, when the skylight 2 is rotated upward to open the window frame 1, the engagement tool 15 is disengaged,
First, the elastic force of the leaf spring 4 causes the skylight 2 to initially rotate upward. In the initial stage of opening the skylight 2, the protruding direction of the rod 8 of the gas spring 3 is substantially perpendicular to the rotating direction (arrow a) of the skylight 2 as shown by the arrow b in FIG. The elastic force of 3 is not efficiently converted into the force for rotating the skylight 2, but the elastic biasing direction of the leaf spring 4 (arrow c) is the same as the rotating direction of the skylight 2.
The elastic force can be effectively acted as the turning force of the skylight 2, and since the leaf spring 4 is bent most greatly in the initial state when the skylight 2 starts to open, the elastic force is large, and The rotation can be smoothly performed by the auxiliary action of the leaf spring. When the skylight 2 is rotated upward to some extent in this way, the rotational direction of the skylight 2 and the protruding direction of the rod 8 of the gas spring 3 deviate from a right angle, and therefore the elastic force of the gas spring 3 moves the skylight 2 upward. It acts as a rotating force, and the skylight 2 can be rotated to hold the window frame 1 in an open state. Also, skylight 2
When the window frame 1 is closed with, the handle 16 provided at the tip of the skylight 2 is pulled downward so that the skylight 2 is rotated downward against the elastic force of the gas spring 3. Good.

[Advantage of the Invention] As described above, in the present invention, one end of the gas spring is attached to the side end of the skylight and the other end is attached to the window frame, respectively, and the elastic force of the gas spring biases the skylight in the opening direction. In addition, a leaf spring was provided between the window frame and the skylight to urge the skylight in the opening direction by the elastic force of the leaf spring, so the direction in which the elastic force of the gas spring works and the rotation of the skylight. In the initial stage of the rotation of the skylight, which is almost perpendicular to the direction of, the elastic force of the leaf spring acts to rotate the skylight upward, and the skylight can be smoothly opened. It is a thing.
