Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for opening and closing a sunroof of an automobile or the like.

[0002]

[Background of the invention] As shown in Fig. 3, the roof of the car (1)
(2) is provided with a skylight (3), and the skylight (3) has a lid (4)
A sunroof type that can be opened and closed is provided. To open and close the lid (4), attach a bracket (5) to the lower surface of the lid (4) as shown in FIGS. 4 to 6, and attach one end of the tilt link (6) to the bracket (5).
Pivot via (7). The tilt link (6) is rotatably supported at a central portion on a support (8) via a shaft (9).
The roller (10) at the other end is rotatably fitted in the inclined guide groove (12) of the guide plate (11), and the guide plate (11) is moved back and forth by a motor (not shown). Are connected and slid back and forth along a guide rail (15) via a roller (14).

In the above configuration, when the roller (10) of the tilt link (6) is at the high end (12A) of the inclined guide groove (12) of the guide plate (11) as shown in FIG. )
Is in the fully closed state, the motor is activated and the wire (1
When the guide plate (11) is moved in the direction of the arrow in FIG. 5 by 3), the roller (10) of the tilt link (6) rolls on the inclined guide groove (12) of the guide plate (11), and the lower end is moved. (12
B), the tilt link (6) rotates about the axis (9) as shown in FIG.
(4) is fully opened.

[0004]

2. Description of the Related Art In the sunroof opening / closing mechanism,
Roller (10) and guide plate (11) for tilt link (6)
Conventionally, as a means for eliminating backlash with the inclined guide groove (12), a rubber ring (10A) is mounted around the roller (10) as shown in FIG. There is provided a configuration in which the diameter is set slightly larger than the width of the inclined guide groove (12).

[0005]

[Problem to be Solved by the Invention] However, in the above-mentioned conventional configuration, it is said that the operating resistance is increased based on the frictional resistance of the rubber ring (10A) of the roller (10), and the rattling of the rubber ring (10A) is generated. There is a problem.

[0006]

Means for Solving the Problems The present invention solves the above-mentioned conventional problems by providing a tilt link whose center is rotatably supported by a bracket (5) attached to the lower surface of a lid (4). (6), and a roller (10) at the other end of the tilt link (6) can be slid forward and backward along a guide rail (15). Rollably fitted into the groove (12), and the guide plate (1
The roller (10) slides in the inclined guide groove (1)
The lid (4) is fully closed when located at the high end (12A) of (2), and the lid (4) is fully opened when located at the low end (12B), and the inclined guide groove is provided. At both ends of (12), the groove width is gradually reduced toward the groove end so as to be slightly smaller than the diameter of the roller (10), and at the middle part, the groove width is slightly smaller than the diameter of the roller (10). An object of the present invention is to provide a sunroof opening / closing mechanism which is set large.

[0007]

[Function] When the lid (4) is fully closed, the tilt link (6)
Roller (10) is the inclined guide groove (1) of the guide plate (11).
2) is located at the high end (12A),
(A) is gradually reduced so that the groove width is slightly smaller than the diameter of the roller (10) toward the groove end, so that the roller (10) has an inclined guide groove (12) at the high end (12A). It will be in a state to bite into.

When the guide plate (11) is moved in the direction of the arrow in FIG. 5 by the wire (13) from the fully closed state of the lid (4), the roller (10) of the tilt link (6) is moved to the inclined guide groove (12). ) Rolls to the lower end (12B) side. The roller 10 rolls smoothly in the inclined guide groove 12 with little resistance.

When the roller (10) of the tilt link (6) is located at the lower end (12B) of the inclined guide groove (12), the tilt link (6) rotates about the center and one end thereof. When the lid (4) is lifted up, the lid (4) is fully opened.In this state, the lower end (12B) is gradually reduced so that the groove width becomes slightly smaller than the diameter of the roller (10) toward the groove end. As a result, the roller (10) enters the groove (12) at the lower end (12B).

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to one embodiment shown in FIGS. 1 and 2. In the sunroof opening / closing mechanism shown in FIGS. 3 to 5, an inclined guide groove (12) of a guide plate (11).
Indicates the groove width at the high end (12A) and the low end (12B).
It is slightly (e.g., 0.05 to 0.15 mm) becomes smaller as progressively reduced from the diameter of the roller (10) of the tilt link (6) toward the groove end. In the other intermediate portions, the groove width of the groove (12) is set to be slightly larger (for example, 0.1 to 0.25 mm) than the diameter of the roller (10).

In the above configuration, when the lid (4) is in the fully closed state and the fully opened state, as shown in FIGS. 1 and 2, the roller (10) of the tilt link (6) has the high end (12A) or the low end (12B). ), The roller (10) bites into the groove (12) to prevent rattling.

[0012]

[Effects of the Invention] Therefore, in the present invention, rattling of the sunroof opening / closing mechanism is effectively eliminated.

Claims (1)

(57) [Scope of request for utility model registration] An end of a tilt link whose center is rotatably supported on a bracket attached to the lower surface of the lid is pivotally connected, and a roller at the other end of the tilt link is slid back and forth along a guide rail. When the roller is positioned at the high end of the inclined guide groove by the front and rear sliding of the guide plate, the lid is fully closed, and the lid is fully closed. When located at the end, the lid is fully opened, and at both ends of the inclined guide groove, the groove width is gradually reduced toward the groove end so as to be slightly smaller than the diameter of the roller. Is a sunroof opening / closing mechanism, wherein the groove width is set slightly larger than the diameter of the roller.
