Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an opening/closing body that tilts upward with a free end and slides on a roof opening r provided on a vehicle. This invention relates to a sunroof device for a vehicle.

``Prior art'' Conventional sunroof devices include 5, for example, Utility Model 60-1.
There is one disclosed in Publication No. 06827.

That is, the publication states that guide rails are provided along both sides of the roof opening, the base of the opening/closing body is slidably supported on the guide rails, and is driven vertically along the guide rails. A drive base is slidably fitted to the side edge of the guide rail, a cam plate extending along the guide rail is provided on the drive base, and two cam grooves are provided adjacent to each other in the front and rear of the cam plate. A pair of cam pins provided at the base end of a tilting member for tilting and opening/closing the opening/closing body are slidably fitted into both the cam grooves.

When the pair of cam pins and each of the cam grooves are displaced relative to each other, the tilting member is tilted up and the tip is raised and lowered, and the opening/closing body is tilted around the base end to open and close. It is designed to open the roof opening by sliding it while it is open.

``Problems to be solved by the invention'' However, with such conventional sunroof devices,
The tilting member is held by a cam pin and a cam groove provided on the drive base, and the opening/closing body is held by the tilting member, and the holding force of the opening/closing body is determined by the fitting relationship between the cam pin and the cam groove. The holding force of the opening/closing body is weak, and there is a risk of rattling or abnormal noises occurring during opening/closing operations or when stopped.

Therefore, as shown in Figure 1O, a sliding surface 2 is placed on the guide rail l.
A sliding bin 3 is projected from a member that supports the opening/closing body and moves, and the sliding bin 3 is brought into contact with the sliding surface 2 and slid, thereby stabilizing the moving member. In order to prevent the opening and closing body from rattling, a holding member 4 is provided at the end of the guide rail 1 and a holding groove 5 is formed therein. A technique has been proposed in which the opening/closing body is stably supported when the opening/closing body is stopped by moving and fitting into the holding groove 5.

However, even with the proposed technique, although it is possible to stably hold the opening/closing body, the sliding surface of the guide rail 1
Since the holding member 4 is connected to the end of the holding member 4, when the sliding bottle 3 passes through the boundary 6, it does not move smoothly, resulting in problems such as malfunction and abnormal noise.

The present invention has been made in view of these conventional problems, and an object of the present invention is to provide a sunroof device whose opening/closing body can be opened and closed smoothly and reliably.

"Means for Solving the Problems" The gist of the present invention for achieving the above object is to provide an opening/closing body that can be tilted and slidably opened and closed in a roof opening provided on a vehicle. In the sunroof device for a vehicle, guide rails are disposed along both sides of a roof opening.

A base base that pivotally supports the base end of the opening and closing body, and a drive base that is driven vertically along the guide rail in response to opening and closing of the opening and closing body are slidably fitted to the guide rail, The base end of a tilting member for tilting and opening/closing the opening/closing body is supported on the drive base so that the tilting member can be tilted, the tip of the tilting member is pivotally connected to the middle part of the opening/closing body, and the tilting member is A cam pin is provided at the base, and a cam groove into which the cam pin fits is provided in the drive base, and the cam pin and the cam groove are arranged so that the tilting member is raised and lowered when the cam pin and the cam groove are displaced relative to each other. In order to stabilize the opening/closing body, a transfer roller having a larger diameter than the cam pin is pivotally attached to the cam pin so as to be able to transfer and contact the guide surface on the surface of the guide rail.

A horizontal holding member is disposed so as to be connected to the end of the guide rail, and the horizontal holding groove receives the cam pin located at a position floating from the guide surface of the guide rail and maintains the horizontality of the opening/closing body. A sunroof device for a vehicle is characterized in that it is provided with a sunroof device.

"Operation" The tilting opening and closing of the opening/closing body is performed by moving the drive base on the guide rail with respect to the fully closed and stopped opening/closing body. Initially, the raising/lowering member is lying down.

When fully closed, the cam pin of the tilting member is fitted into the cam groove of the drive base and is at one end of the movement stroke, and at the same time, the cam pin is fitted into the horizontal holding groove of the horizontal holding member, so that the cam pin is held. This stabilizes the tilting member, and the opening/closing body firmly maintains the water layer posture without wobbling.

When the drive base is moved to open the opening/closing body, the cam pin moves in the cam groove in the direction along the guide rail, and due to this displacement, the cam pin also moves to the upper F, which causes the lifting member to move up and down. -Gari.

The opening/closing body moves #A to open, tilts to fully open, and then moves the base base and drive base backward along the guide rail, and the opening/closing body slides open.

When the opening/closing body begins to open, the cam pin is pulled out of the horizontal holding groove of the Bokuto holding member and moved to one of the guide surfaces of the guide rail.
A transfer roller pivotally connected to a cam pin rests on the guide surface of the guide rail.

As soon as the cam pin is pulled out of the horizontal holding groove, it floats off the guide surface of the guide rail, and the transfer roller simply rests on the guide surface, so it moves smoothly from the water retaining member to the guide rail. It will be held in

During the opening/closing operation and when it is opened and stopped, the transfer roller contacts the guide surface on the surface of the guide rail and transfers or stops, and the opening/closing body performs the opening/closing operation stably and stops reliably. .

When closing the opening/closing body, operate in the reverse order to fully close it. The rolling roller comes off the guide rail, the cam pin enters the horizontal holding groove of the horizontal holding member, and is held as described above when the opening/closing body is fully closed.

When moving from the guide rail to the horizontal holding member, the transfer roller simply comes off the guide surface and the cam pin simply enters the horizontal holding groove, so the movement is smooth and there is no wobbling.
