Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a roof window for a vehicle such as a ship or a vehicle, and is designed to smoothly open and close an opening in the roof using a cover member. The present invention relates to the provision of a roof window that is intended to prevent the generation of abnormal noises such as impact noises caused by various parts of equipment during opening and closing operations.

(Prior Art) Conventionally, an opening is formed in the roof of a vehicle such as a passenger vehicle, and a cover member is provided to open and close the opening, and the cover member is movable back and forth by a drive device. In a roof window for a vehicle in which the opening is closed by being raised or lowered from a position corresponding to the opening, the cover member and the drive device are connected via a link mechanism (for example, 49-15216, JP-A-53-98623).

(Problems to be Solved by the Invention) In the conventional link, both ends of the link are rotatably supported by the cover member and the drive device via pivots, so the cover member can easily move up and down. There is wobbling in the direction, and due to this wobbling,
Various problems have occurred, such as the opening/closing operation not being smooth, and the occurrence of abnormal noises such as collision noises caused by various parts of the device when the drive device is started.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a roof window for a vehicle that prevents the cover member from shaking in the vertical direction due to the looseness of the link equipment.

(Means for Solving the Problems) The present invention is characterized by an opening formed in the vehicle roof, which is movable in the front and rear directions below the opening, and which can be opened and closed from below. In order to achieve this, a cover member whose front part is rotatable and whose rear part can move up and down, brackets provided in a downwardly protruding shape on both left and right sides of the cover member, and brackets provided on the lower surface side of the roof on both the left and right sides of the opening are provided. a guide rail arranged in parallel along the direction; a movable body slidably fitted to the guide rail and moved in the front-back direction by a drive device and disposed behind the bracket; an engaging body that connects the movable body and the bracket; a cam member that is provided on the guide rail and has a cam surface that increases in height toward the front; and a cam engaging body provided on the bracket to slide and fit the cover member into the opening, and the front part of the engaging body and the bracket rotate via a pivot having a horizontal axis in the left-right direction. The pivot portion is movably pivoted, and the pivot portion is provided with a pressing means that presses the engaging body and the bracket in the axial direction of the pivot in order to apply frictional resistance to the relative rotation of the engaging body and the bracket. , the rear part of the engaging body and the movable body are rotatably connected via a support shaft having an axis parallel to the pivot shaft, and the cam engaging body or the bracket is attached to the engaging body and the movable body. A locking portion is provided to prevent the engaging body from rotating more than a predetermined amount downward about the support shaft so as to be held apart from the guide rail.

(Function) According to the present invention, the opening is opened by moving the cover member rearward via the movable body. At this time,
The cam engaging body slides on the cam surface and descends. As a result, the rear part of the cover member moves downward centering on the front part. At this time, since the cover member is urged downward by its own weight, rotation occurs at the pivot portions at both the front and rear ends of the engaging body, and the rear part of the cover member descends downward. During this descent, frictional resistance is applied to the front pivot portion of the engaging body by the elastic pressure means, but the weight of the cover member rotates the pivot portion against the frictional resistance. In the lowered state, the engaging body and the movable body engage with each other via the locking portion, and the cover member is prevented from lowering by a predetermined amount or more. Further, at this time, since the pivot portion between the engaging body and the bracket is resiliently supported by the compression means, rattling around the pivot of this pivot portion is prevented. Note that the pivot between the engaging body and the movable body is not provided with a play prevention means, but since the rear part of the cover member moves up and down centering on its front part, the cover member moves up and down. Rotation must occur at the pivot parts at both ends of the engaging body, but since one pivot part is elastically supported and given frictional resistance, the rotation of the other pivot part is restricted, and the engagement body and Shaking of the pivot with the moving body is prevented.

Next, to close the opening, the cover member is moved forward via the moving body. This forward movement causes the cam member to slide on the cam surface and raise the rear portion of the cover member. At this time, the front pivot portion of the engaging body rotates without wobbling against the pressing means.
