Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an opening/closing device for an opening/closing member such as a sunroof in a vehicle.

(Prior Art) In general, this type of opening/closing device will be explained by taking as an example a sunroof opening/closing device whose one end is pivotally connected to a roof panel to open and close an opening formed in the roof panel. 1977-
As shown in Japanese Patent No. 74211, one end of the handle is pivotally attached to the free end side of the sunroof, one end of a link is pivotally supported in the middle of the handle via a shaft, and the other end of this link is is pivotally attached to the roof panel, and when the handle is swung, the link is rotated to the inside of the handle and folded, thereby closing the sunroof.

In the opening/closing device described above, when the handle is used for deployment, the link is deployed with respect to the handle, and the free end side of the sunroof is moved against the roof panel by the link and the handle. By pushing upwards,
While opening the opening provided in the roof panel, the opening of the roof panel is opened by folding the link with respect to the handle and lowering the free end side of the sunroof by performing a folding operation using the handle. It is designed to be closed by the sunroof.

(Problems to be Solved by the Invention) However, in the above-mentioned opening/closing device, when the link is opened with respect to the handle by the unfolding operation of the handle and the sunroof is opened, the automobile may vibrate or the like. If the sunroof rattles, the link may swing, and the link may rotate in the folding direction relative to the handle, causing the sunroof to close inadvertently.

This invention was developed in view of the above circumstances.
The purpose is to use an extremely simple configuration,
To provide an opening/closing device for an opening/closing member in which the link does not inadvertently rotate in the folding direction with respect to the handle when the sunroof is opened.

(Means for Solving the Problems) The present invention provides a handle pivotably attached to one of an opening/closing member in a vehicle and a base member supporting the opening/closing member, and a free end of the handle at one longitudinal end. a pair of links pivotally connected to the other end of the opening/closing member in the longitudinal direction and a base member supporting the opening/closing member, and the links are provided so as to be able to approach and separate from each other. By bringing the two links close together, the two links can be separated from the other of the opening/closing member and the base member supporting the opening/closing member, and the opening/closing member can be opened/closed by expanding or folding the link with respect to the handle. In the opening/closing device for an opening/closing member in a vehicle, both of the links are provided with springs that bias the links in a direction of separation, and a first protrusion is formed on the connection side of the links of the handle, and the links are connected to each other. A second protrusion is formed that contacts the first protrusion near the end position of the swing in the expansion direction of the link, and when the second protrusion abuts the first protrusion, the second protrusion is caused to contact the first protrusion. The present invention is characterized in that both links are moved in a direction toward each other against the spring to overcome the first protrusion.

(Function) According to the present invention, as the link swings in the deployment direction with respect to the handle, the second protrusion comes into contact with the first protrusion and when the second protrusion crosses over the first protrusion, the spring is released. Due to the spring reaction force generated, the link is urged in the unfolding direction with respect to the handle, and the link does not inadvertently swing in the folding direction with respect to the handle.

Even if b tries to swing in the folding direction (clockwise in FIG. 7) with respect to the handle 3, the second protrusions 7, 7 abut against the first protrusions 6, 6, and the links 4a, 4b Since the sunroof 2 is prevented from swinging in the folding direction with respect to the handle 3, there is no risk of the sunroof 2 inadvertently lowering and closing the opening 11, and the sunroof 2 is reliably held in the open position. It is.

On the other hand, in order to close the opening 11 opened as described above, the handle 3 is moved to the shaft 33.
When the links 4a and 4b are forcibly swung in the counterclockwise direction in FIG. After getting over the first protrusions 6, 6 again, the links 4a, 4b are free to swing in the folding direction with respect to the handle 3, so the handle 3 can be swung at a predetermined angle counterclockwise in FIG. The links 4a and 4b can be folded against the handle 3 as shown in FIG. 6 by switching the direction of the swing clockwise in FIG. 7.

(Effects of the invention) As described above, the present invention provides a handle that is pivotally attached to one of an opening/closing member in a vehicle and a base member that supports the opening/closing member, and a handle that is pivotally attached to one of the opening/closing members and a base member that supports the opening/closing member. A pair of links are provided which are connected to each other and whose other ends in the longitudinal direction are pivoted to the other of the opening/closing member and the base member supporting the opening/closing member, and the links are provided so as to be movable toward and away from each other. Proximity of the links allows these links to be separated from the other of the opening/closing member and a base member supporting the opening/closing member, and the opening/closing member is opened/closed by expanding or folding the link with respect to the handle. In an opening/closing device for an opening/closing member in a vehicle, both links are provided with springs that bias the links in a direction of separation, and a first protrusion is formed on the connection side of the links in the handle, form a second protrusion that abuts the first protrusion near the swinging end position in the direction of expansion of the protrusion, and when the second protrusion abuts the first protrusion, the two links are By moving the link in a direction approaching each other against a spring and overcoming the first protrusion, the link can be separated from the other of the opening/closing member and the base member supporting the opening/closing member in the separating direction. By effectively utilizing a spring that biases the handle and the link, the first
With an extremely simple configuration that only requires the formation of the second protrusion and a small number of parts, the second protrusion is caused to ride over the first protrusion near the swinging end position of the link in the direction of expansion with respect to the handle, and the spring is released. The spring reaction force urges the link in the unfolding direction with respect to the handle, and prevents the link from inadvertently swinging in the folding direction with respect to the handle, thereby reliably holding the opening/closing member in the open position. I was able to do this.
