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 elevating 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 conventional lifting device using a toggle mechanism, when the rear part of the movable panel is lifted up and in the open state, there is no device to actively lock this state. There was a risk that it would rattle and rotate due to vibration and wind pressure.

(Means for Solving the Problems) The present invention provides a movable panel that removably fits into an opening in a vehicle roof. In the sunroof device, the lifting device includes an operating handle pivotably supported on a movable panel side and a deployment lever pivotably supported on a base fixed to the roof side. The deployment lever is pivotally supported in the middle of the operating handle to constitute 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 engaged with the base. A locking device for removably engaging and fixing is provided, and the locking device removably engages with a recess provided in either one of the opposing sides of the deployment lever or the base. The above-mentioned problem is solved by providing a configuration that includes a convex portion provided on the other side, and an elastic member that urges one of the concave and convex portions toward the other side.

(Example) Hereinafter, an example 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 covered by a removable movable panel 3. The roof opening 2 is surrounded by a roof frame 4.

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. A pair of left and right hinge housings 6 are fixed to the front peripheral wall of the roof opening 2, and a fitting hole 7 is formed in the housing 6 to removably receive the tongue piece 5. With the tongue piece 5 fitted into the insertion hole 7, the movable panel 3
is rotatably supported 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. This elevating device 9 includes an operation handle 12 rotatably supported via a pivot 11 to a bracket 10 fixed to the rear lower surface of the movable panel 3, and a pivot supported to a base 13 fixed to the roof frame 4. The operating handle 1 has a deployment lever 15 rotatably supported via a lever 14.
2 and the deployment lever 15 are connected via a pivot 16 to form a toggle mechanism.

The lifting device 9 is configured to be disassembled at a pivot point 11 between the bracket 10 and the operating handle 12, or at a pivot point 16 between 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 pins 17, 17 are fitted into the left and right sides of the operating handle 12 so as to be able to move forward and backward, and these pins 17, 17 are urged outward by a spring 18. A pair of left and right brackets 10 are provided, and holes 19, 1 are provided in which the pins 17, 17 are fitted so as to be freely insertable and removable.
9 is provided. A handle 20 is provided perpendicularly to each pin 17, and both handles 2
By squeezing the pins 0 and 20 close to each other, the pin 17 and the hole 19 are disengaged, and the movable panel 3 can be removed from the roof 1. pin 1
The outer end surface of 7 is trimmed, and the operation handle 1
Just push 2 between brackets 10 and 10,
The pin 17 and the hole 19 fit together with a single 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, 15 are disposed inside the base 13.
An operating handle 12 is located between 15 and 15. A pin 21 biased by a spring is fitted into the side surface of the base 13 above and behind the pivot portion 14 between the base 13 and the deployment lever 15, and is biased by a spring so as to protrude freely toward the deployment lever 15 side. 21 is a convex portion that cooperates with a concave portion 22 to be described later.

A concave portion 22 is provided on the end surface of the base side of the central portion of the deployment lever 15 in the longitudinal direction, into which the convex portion, that is, the pin 21 is removably fitted. This pin 21 and recess 22 constitute a locking device 23.

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

FIGS. 3 and 4 show another embodiment, in which the front end of the operating handle 12' is formed into two forked parts, and a bracket 10' is disposed between these two forked parts, and a pivot pin is attached to the bracket 10'. 17', 17' and spring 18'
is built into this bracket 10'.

Then, the operating handle 12' and the bracket 1
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 connection of the base 13' is released.

FIG. 5 shows still another embodiment, in which the base 13''
The pivot portion 14'' of the expansion lever 15'' and the expansion lever 15'' are configured to be removable. That is, pins 25 and 26 that protrude in opposite directions are fixed to both ends of the deployment lever 15'', respectively, and one pin 25 is removably inserted into a hole in the base 13'' to connect the pivot portion 14''. The other pin 26 is slidably inserted into a bearing lug 27 of the operating handle 12'' to constitute a pivot portion 16''. By pushing the deployment lever 15'' in the direction of the arrow in FIG. 5 against the tension of the spring 28, the coupling of the pivot portion 14'' is released.

In the embodiment shown in FIG. 5, the deployment lever 15'' is biased toward the base by the spring 28, so that the protrusion that cooperates with the recess 22'' of the locking device 23'' between the base 13'' and the deployment lever 15'' The pin that is
3'', 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.
The fully open state can be maintained reliably. Also,
Even if the locking device is locked and unlocked many times, the locking function will not be impaired due to wear of various parts.
