Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a lid opening / closing device for opening and closing a lid of a sunroof or a top light provided on a roof of a structure such as a house.

[Prior Art] Conventionally, as such a lid opening / closing device, one in which a lid is tilted up is known.

This simple tilt-up type is designed to perform the lid up / down operation by a swing link mechanism or the like. However, such a simple tilt-up type does not provide a sufficient feeling of opening, and therefore, a slide type in which the lid is tilted up is also proposed.

[Problems to be Solved by the Invention] However, such a conventional tilt / slide lid opening / closing device includes a link mechanism for tilting operation,
Including the link mechanism operated in the tilt-up state,
A slide mechanism for sliding the lid is required, and the structure is complicated and expensive.

The object of the present invention was made in view of the above-mentioned conventional problems, and in order to obtain ventilation and a great feeling of openness during rainfall,
It is an object of the present invention to provide a lid opening / closing device which has a simple structure and can be inexpensive even though the lid can be tilted up / down and slid.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a body frame fixed to an opening formed in a structure, a lid for opening and closing the opening of the body frame, and the body. A guide rail that is fixed to the inside of the frame and that also has a linear portion that extends along at least the upper edge of the side wall of the main body frame and a curved portion that is continuous with the linear portion and that gradually decreases toward the front; Provided on the side wall,
A slide rail means for rotatably supporting the rear end portion of the lid, and a lower end portion of which is connected to a slider which is extended to the lower front side of the lid and slidably engaged with the guide rail. And a drive cable that is housed in the guide rail and has one end connected to the slider and is driven by a drive means.

[Operation] According to the present invention, when the slider is located at the lower end of the curved portion of the guide rail, the lid with the leg piece connected to the slider extending forward and downward is slid. The rear end portion, which is rotatably supported by the rail means, pivots about the rear end portion to obtain the closed state.

Then, when the slider is slid backward from the open state by the drive means via the drive cable, the slider first slides along the curved portion of the guide rail. Then, the lid is moved backward by the slide rail means that supports the rear end while raising the front of the lid. Thus, the maximum tilt-up state is obtained in the continuous portion of the curved portion and the straight portion of the guide rail. If the drive cable is further driven by the drive means from the maximum tilt-up state, the slider slides along the linear portion of the guide rail, and the lid moves rearward while maintaining the tilt-up state, The maximum open state of the opening of the body frame is obtained.
