Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a sunroof device for a vehicle.

(Prior art) A front edge of a movable panel that removably fits into an opening in a vehicle roof is rotatably supported around the opening, and a rear edge of the movable panel is supported so that it can be lifted up via a lifting device. Many of the sunroof devices that have been developed employ a toggle latch mechanism as the lifting device.

That is, a toggle mechanism is formed by pivoting an operating handle pivotably supported at the rear of the movable panel to a deployment lever pivotably pivoting on the roof side, and when the operating handle is rotated. When the deployment lever passes the bottom dead center or top dead center, the movement of the operating handle is fixed and the movable panel is maintained in the open or closed state.

(Problems to be Solved by the Invention) In the above-mentioned conventional lifting device using a toggle mechanism, when the rear part of the movable panel is lifted up and opened, there is no device to actively lock this state. There was a risk that it would rattle and rotate due to vibration or wind pressure.

(Means for Solving the Problems) In order to solve the above problems, the present invention takes the following measures. That is, the feature of the present invention is that the front edge of the movable panel that removably fits into the opening of the vehicle roof is rotatably supported around the opening, and the rear edge of the movable panel can be moved up and down. In the sunroof device supported via the device so as to be freely lifted, the elevating device has an operation handle pivoted on a movable panel side and a deployment lever pivoted on a base fixed to the roof side. A deployment lever is pivotally supported in the middle of the operating handle to form a toggle mechanism, and when the operating handle is rotated to raise the rear part of the movable panel to the highest level, the deployment lever is removably engaged with the base. The point is that a locking device is provided for fitting and fixing.

(Example) Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

1 and 2, an opening 2 is provided in a vehicle roof 1, and the opening 2 is provided with a removable movable top.
The roof frame 4 is surrounded by the roof frame 4 and the roof space 2'1.

A pair of left and right tongue pieces 5 projecting forward are fixed to the lower surface of the front edge of the movable panel 3. 1t11118 of roof opening 2
A pair of left and right hinge housings 6 are fixed to the wall portion, and a fitting hole 7 is provided in the housing 6 to freely receive the tongue piece 5 therein. With the tongue piece 5 fitted into the insertion hole 7, the movable panel 3 is supported rotatably about an imaginary line 8 above its front edge.

The rear part of the movable panel 3 is supported by a lifting device 9 that can be lifted freely. The lifting device 9 includes an operation handle 12 rotatably supported via a pivot 11 to a bracket 10 fixed to the lower surface of the movable panel 3, and a base 13 fixed to the roof frame 4. It has a deployment lever 15 rotatably supported via a branch 14, and the middle part of the operating handle 12 and the deployment lever 15 are connected via a pivot 16 to form a toggle mechanism. .

The above lifting/lowering position 9 consists of a bracket 10 and an operating handle 1.
It is constructed such that it can be disassembled at either the two pivot points 11 or the pivot points 16 of the deployment lever 15 and the operating handle 12. In this embodiment, the pivot portion 11 between the bracket 10 and the operating handle 12 is configured to be freely releasable.

That is, a pair of left and right bins 17.17 are fitted into the left and right sides of the operating handle 12 so as to be movable forward and backward.
17 is urged outward by a spring 18. A pair of left and right brackets 10 are provided, and these brackets 10.10 are provided with holes 14.19 into which the bins 17.17 can be freely inserted and removed.Handles 20 are perpendicular to each of the bins 17, respectively. provided, both handles 20
．． By squeezing the bottles 1 and 20 close to each other,
7 and the hole 19 are released, and the movable panel 3 is moved to the roof 1.
It can be freely removed from the The outer end surface of the bottle 17 is trimmed, and by simply pushing the operating handle 12 between the brackets 10 and 10, the bottle 17 and the hole 19 are fitted in one-touch operation.

A pair of left and right bases 13 are fixed to the roof frame 4, and a pair of left and right deployment levers 15.1 are installed inside the base 13.
5 is disposed, and an operating handle 12 is located between the expansion levers 15° and 15. A pin 21 biased by a spring so as to protrude forward and backward from the deployment lever 15 (1111-) is fitted onto the side surface of the base 13 above and behind the pivot portion 14 between the base 13 and the deployment lever 15.

On the other hand, a recess 22 into which the bottle 21 is removably fitted is provided on the end surface of the base side of the central portion of the deployment lever 15 in the longitudinal direction. A lock device 23 is constituted by the bottle 21 and the recess 22.

That is, when the operating handle 12 is rotated to raise the rear part of the movable panel j to the highest level and fully open the opening 2, the base 13
The recess 22 of the deployment lever 15 engages with the bin 21 at the upper front end of the lever 15 to lock the fully opened state. Further, when the movable panel 3 is lowered to fully open the opening 2, the recess 22 of the deployment lever 15 engages with the rear bin 21 to lock the fully opened state.

3 and 4 show other embodiments, in which the operating handle 1
The front end of 2' is formed into two forked parts, and a bracket 10' is disposed between these two forked parts, and a pivot pin 17'
, 17' and spring 18' are attached to this bracket 1.
Built in 0'.

A support portion 24 is provided at the front end of the base 13' to support the operating handle 12' so that the operating handle 12' does not fall when the operating handle 12' and the bracket 10' are uncoupled.

FIG. 5 shows still another embodiment, in which the pivot portion 14'' between the base 13'' and the deploying lever 15'' is configured to be removable. That is, at both ends of the deploying lever 15'', there are Bins 25 and 26 protruding in opposite directions are fixed, one of which is removably inserted into a hole in the base 13'' to constitute the pivot 14'', and the other is inserted into the operating handle 12''. It is slidably inserted into the bearing lug 27 to constitute a pivot portion 16''. The pin 26 fitted into the bearing lug 27 is urged outward by a spring 28. By pressing the deployment lever 15'' in the direction of the arrow in FIG. 5 against the tension of the spring 28, the
4" is uncoupled.

In the embodiment shown in FIG. 5, the deployment lever 15'' is attached to the spring 2
Since it is biased toward the base by 8, the base 13''
and the locking device 23″ between the deployment lever 15″ and the bin 21″
may be fixed to the base 13'' without being biased by a spring, or may be a convex portion integrally molded with the base 13''.

(Effects of the Invention) According to the present invention, when the movable panel is fully opened, the toggle mechanism of the lifting device is completely locked, and the fully opened state can be reliably maintained.
