Description

[Detailed explanation of the idea] The present invention relates to a vehicle ceiling window opening/closing device.

As is well known, ceiling windows for vehicles called so-called sunroofs include swing-type opening/closing windows that include a window cover that swings to open and close a roof opening, and an opening/closing device that swings the window cover. The opening/closing device used for this type of window uses a toggle mechanism in which an operating lever is swingably supported on the window cover and is connected to a swing arm that is swingably supported on the roof. many. In devices using such a toggle mechanism, the operating lever is held fixed when the arm passes the bottom dead center or top dead center, and the window cover is maintained fully open or fully closed. However, in the opening/closing device described above, there is a risk that the operating lever may rotate unexpectedly due to vibration or the weight of the window cover or the like, and may also become rattled.

Therefore, in order to solve the above-mentioned problem, a lock mechanism designed to prevent accidental rotation of the operating lever has been proposed, for example, in Japanese Patent Laid-Open No. 51-139017, Japanese Patent Laid-Open No. 54
-Disclosed in Publication No. 27122.

That is, the device described in the above-mentioned Japanese Patent Application Laid-open No. 139017/1985 has a pin biased by a spring interposed between a swing lever and a roof-side support member that pivotally supports the swing lever. This was to prevent accidental rotation of the swing lever in the fully open and fully closed states.

However, in the conventional device described above, the swing lever rotates more than 180 degrees around the pivot portion of the roof-side support member, so the roof-side support member has to extend long to both sides around the pivot portion. It was something that had to be established. Therefore, the overall size of the device becomes large, which limits the roof thickness in particular.
It was a problem.

Furthermore, the device described in Japanese Patent Application Laid-Open No. 54-27122 attempts to prevent accidental rotation of the operating lever by interposing a detent member between the swing lever and the operating lever. To release the lock, the release member must be operated, and the lock cannot be operated with a single touch, and the lock can only be locked when the lock is fully closed.

Therefore, the present invention has been developed for a ceiling window of a vehicle that is equipped with a locking mechanism that can reliably maintain the fully open and fully closed states by simply rotating the operating lever, and that also allows the device to be made more compact. The purpose is to provide a switchgear.

Therefore, the feature is that a window cover is provided to be swingable in the vertical direction to open and close the roof opening, and one end of the operating lever is pivotally connected to the window cover so as to be able to swing freely. One end of the swinging arm is pivotally connected to the middle part in the direction, the other end of the swinging arm is pivotally connected to the roof side, and the said swinging is performed by rotating the operation lever around the window cover pivoting part. In the vehicle ceiling window opening/closing device configured to swing the window cover in the vertical direction by rotating an arm around a roof-side pivot portion, the swing arm is provided with an engaged portion. , the operating lever is provided on both sides of the swinging lever via a pivotally connected portion, and is engaged with the engaged portion through a catching resistance when the operating lever is rotated to fully open and close the window cover. The main feature is that a fully open engaging portion and a fully closed engaging portion are provided which are removably engaged.
