In the above-described conventional depression, a roller stop mechanism was provided (see paragraph number “0016” of FIG. 4 and FIG. 5). The stop mechanism includes a substantially L-shaped stop member pivotally supported by a shaft, a hook member that stops the rotation of the stop member, and a spring member that returns from a position stopped by the hook member. .

Japanese Patent Laid-Open No. 9-109776

However, the above-described conventional vehicle tonneau cover device requires a hook member for stopping the rotation of the substantially L-shaped stop member, its structure is complicated, and when releasing the prohibition of movement of the tonneau cover, It is necessary to remove the hook member from the pawl of the stop member (see paragraph number “0019” of Patent Document 1 and FIG. 5B), and there is a problem that the releasing operation of the hook member is troublesome.

Accordingly, the present invention has been made in view of the above-described problems of the prior art, and the object of the present invention is to allow the tonneau cover to be unlocked simply and quickly. It is.

The present invention has been made to achieve the above object, and the present invention is characterized by the following points.

First, the tonneau cover locking mechanism is provided with an engaging portion in a disk-shaped locking member provided in a recess, and the engagement of the locking member from the receiving position of the tonneau cover's terminal side boss to the position where it does not reverse by the entraining biasing force of the tonneau cover. The joint is rotated.

Second, the receiving position is determined by the first restricting portion and the spring.
3rdly, it positions by the 2nd control part to the position which is not reversed, and hold | maintains the terminal side boss | hub of a tonneau cover.
The present invention may be characterized by the following points.

That is, the engaging part has an opening on the inner peripheral side of the recess. In this case, the terminal-side boss can be firmly held at a position where the tonneau cover is not reversed by the urging urging force of the tonneau cover.
The present invention may be characterized by the following points.

That is, the recess is provided in the vehicle interior panel. In this case, the number of parts can be reduced.
The present invention may be characterized by the following points.

That is, a damper for braking the lock member is provided. In this case, when the engaging portion of the disk-shaped lock member is rotated via the tonneau cover from the position where the tonneau cover is not reversed by the entraining biasing force of the tonneau cover, the braking force by the damper is applied. Can be improved, and the texture at that time can be improved.
More specifically, there should be a time lag from when the hand is released at the time of release until the terminal side boss of the tonneau cover is released from the disk-shaped lock member, and the reverse force assists the lock / unlock operation. Thus, the texture can be improved.

According to the present invention, the position of the tonneau cover that is not reversed by the urging force of the tonneau cover is positioned by the second restricting portion. By rotating the engaging portion of the lock member, the locked state of the tonneau cover can be easily and quickly released.

In addition to this, since the receiving position of the terminal side boss of the tonneau cover is positioned by the first restricting portion and the spring, it is possible to prevent the receiving position from being shifted due to vibration of the vehicle or the like.

(Engagement part 52)
As shown in FIGS. 1, 4, and 5, the engaging portion 52 is recessed from the periphery of the lock member 50 and can receive the terminal-side boss 21 of the tonneau cover 20. The engaging portion 52 has a flat surface recessed in a substantially fan shape or substantially V shape, the bottom surface and the inner surface are closed, and the upper surface and the outer surface on the upper wall side are opened.

As shown in FIGS. 1 and 4, the engaging portion 52 communicates with the opening side surface of the engaging portion 52 and the guide groove 32 at a position corresponding to the guide groove 32 of the recess 31. The terminal-side boss 21 inserted through is received, and the position is referred to as an “accepting position”.
When the lock member 50 is rotated from the “accepting position”, the opening side surface of the engaging portion 52 is blocked by the inner peripheral surface of the peripheral wall of the recess 31. For this reason, if the lock member 50 is rotated in a state where the terminal-side boss 21 is received in the engaging portion 52, the terminal-side boss 21 cannot be removed from the lock member 50.

Thereafter, as shown in FIGS. 9 and 10, when the lock member 50 is rotated at a predetermined angle, for example, about 180 degrees from the “accepting position”, the lock member 50 is not reversed by the urging urging force of the tonneau cover 20. It is called “a position that does not reverse”.
(Tooth 53)

The spring 60 urges the first contact surface 54 of the lock member 50 toward the first restricting portion 44 of the base member 40 as shown in FIGS.

The spring 60 is located in the cylindrical shaft portion 42 of the base member 40, and has one winding end latched on the shaft portion 42 and the other winding end fitted into the outer periphery of the shaft portion 42. Hanging on part 51. The first contact surface 54 of the lock member 50 is biased toward the first restricting portion 44 of the base member 40 by the unwinding force of the spring 60. The spring 60 is set to have a weak spring force so that the “accepting position” of the lock member 50 does not move due to vehicle vibration or the like.
(Damper 70)
The damper 70 brakes the lock member 50 as shown in FIGS. As the damper 70, a rotary oil damper using the viscous resistance of silicon oil is used.

As shown in FIGS. 1 and 8, the damper 70 is attached and fixed to the damper holding portion 43 of the base member 40, and meshes the gear 41 with the tooth portion 53 of the lock member 50.
(how to use)
Next, a method of using the above-described tonneau cover lock mechanism will be described.
As shown in FIG. 3, the tonneau cover 20 in the wound state is pulled out as shown in FIG. 2 against the urging force, and the terminal-side boss 21 of the recessed portion 31 is pulled out as shown in FIG. Fit into the guide groove 32.

As shown in FIG. 4, the terminal-side boss 21 is fitted inside the opening of the concave engaging portion 52 of the lock member 50 in the “receiving position” (see FIGS. 1 and 4) from the end portion of the guide groove 32. .
Thereafter, the terminal-side boss 21 is held and the lock member 50 is rotated toward the “non-inverted position” (see FIGS. 9 and 10).
When the lock member 50 is rotated about 180 degrees, the second abutment surface 55 abuts against the second restricting portion 45 of the base member 40 and is not reversed by the urging urging force of the tonneau cover 20. Stop.

The tonneau cover 20 is locked in the pulled-out state toward the entraining urging force, and is in a closed state in which the upper part of the luggage room at the rear of the vehicle is covered.
On the other hand, in order to release the locked state, the terminal-side boss 21 is held and the lock member 50 is rotated toward the “receiving position” (see FIGS. 1 and 4).
At this time, the urging urging force of the tonneau cover 20 acts, and a rotational force that tries to rotate the lock member 50 toward the “accepting position” acts.

At that time, the gear 41 rotates due to the engagement between the tooth portion 53 of the lock member 50 and the gear 41 of the damper 70, and the braking force of the damper 70 acts.
For this reason, the lock member 50 rotates slowly and quietly toward the “receiving position” (see FIGS. 1 and 4).
When the lock member 50 is rotated to the “accepting position”, the first contact surface 54 comes into contact with the first restricting portion 44 of the base member 40, and the rotation of the lock member 50 is stopped.

In the “receiving position”, the opening of the engaging portion 52 of the lock member 50 coincides with the guide groove 32 of the concave portion 31 and is opened.
For this reason, by pulling out the terminal-side boss 21 from the engaging portion 52 through the guide groove 32, the locked state is released and the tonneau cover 20 can be opened.
The entire contents of the specification, claims, drawings, and abstract of Japanese Patent Application No. 2011-062353 filed on March 22, 2011 are incorporated herein as the disclosure of the specification of the present invention. Is.
