[Prior art]
Convertible vehicles such as open cars in which a roof panel (roof portion) and a rear window (rear window) can be freely stored in a luggage space (trunk room) are widely known. In this type of vehicle, as shown in FIG. 6, movement of a roof panel 1, a rear window 2, a package tray 3, and a luggage panel 4 is ensured.
[0003]
FIG. 6A shows a state in which the roof panel 1 and the rear window 2 are in the closed position. To bring this closed position to the state shown in FIG. The glass 2 is raised and laid down rearward, and the roof panel 1 connected to the rear window glass 2 is moved rearward while keeping its posture substantially horizontal. At this time, the luggage panel 4 is opened forward around the pivot point 5 (see FIG. 6B).
Since the rearward sloping rearward of the rear window 2 causes interference between the package tray 3 and the roof panel 1 moving rearward, the package tray 3 is erected forward as shown in FIG. The interference between the panel 1 and the package tray 3 is prevented.
[0004]
The roof panel 1 and the rear window 2 are stored in the luggage space 6 in the state of FIG. 6C, and then the slide board 7 of the package tray 3 is pulled out rearward (see FIG. 6D).
After confirming that the roof panel 1 and the rear window 2 are stored in the luggage space 6, the luggage panel 4 is fully closed (see FIG. 6E).
[0005]
In order to change from the open state shown in FIG. 6E, that is, the fully opened state to the fully closed state shown in FIG. 6A, the above operation may be reversed.
In order to load luggage into the luggage space 6 with the roof fully closed as shown in FIG. 6 (a), the lock between the luggage panel 4 and the body is released, and the rear portion is lifted so that the luggage panel 4 is opened rearward. Just do it.
[0006]
An example of the movement of the roof panel and the luggage panel described above is disclosed in JP-A-8-230484, and an example of the movement of the package tray is disclosed in German Patent No. 4446483. In this known example, a substantially U-shaped auxiliary frame is disposed in a luggage space at a rear portion of a vehicle, a support plate is fixed to an end of an opposing leg of the auxiliary frame, and the luggage panel is swung parallel quadrilateral link mechanism. , And the link mechanism enables the luggage panel to be opened rearward.
The front opening of the luggage panel is performed by rotating the luggage panel together with the support plate and the swinging parallelogram link mechanism under the assisting force of the hydraulic cylinder around the support pipe of the auxiliary frame extending in the vehicle width direction. Done. At this time, the rear part of the luggage panel is locked to the support pipe of the auxiliary frame by the lock device.
[0007]
[Problems to be solved by the invention]
As described above, in the convertible vehicle, in order to make the vehicle open, the luggage panel is opened forward, the roof panel and the rear window are stored in the luggage space, and then the luggage panel is closed. During this operation, the rear of the luggage panel is locked to the body of the vehicle using a locking device.
[0008]
As shown in FIGS. 4 and 5, the lock device 8 has a pawl 10 whose one end is pivotally supported on a base plate 9, and a claw portion 12 which can be engaged with a step portion 11 of the pawl 10. 9 and a latch 13 pivotally supported. The latch 13 has a groove 15 for receiving a striker 14 and is connected to the pawl 10 via a spring 16.
When the striker 14 fixed to the luggage panel enters the groove 15, the striker 14 rotates the latch 13 in the counterclockwise direction to engage the claw portion 12 with the step portion 11, and from the unlocked state of FIG. The locked state shown in FIG. 5 is created, and the luggage panel is fixed to the body.
[0009]
In order to release the locked state and enable the luggage panel to be opened rearward, the motor M is operated by key operation and the protruding piece 17 at the free end of the pole 10 is pushed in the direction A, or the unlocking member 18 is operated by operating the handle. Is brought into contact with the protruding piece 17, which is pushed in the direction A to move the pawl 10 against the urging force of the spring 16, so that the step 11 of the pawl 10 and the claw 12 of the latch 13 are engaged. It is only necessary to release the latch and move the latch 13 to the unlock position in FIG.
[0010]
By the way, since the center of rotation of the luggage panel does not coincide with the engagement point of the striker and the latch of the lock device, a slip occurs in the engagement portion between the striker and the latch during the front opening of the luggage panel. Due to the change in load on the engagement between the striker and the latch due to the driving force of the luggage panel and the weight of the luggage panel, slippage occurs in the engagement between the striker and the latch, causing a problem that the luggage panel's front opening locus does not become constant, In some cases, the luggage panel may interfere with the body or the like.
In addition, the above-mentioned troubles are exacerbated by misalignment of the left and right movements during opening of the luggage panel, vibration, unexpected external force, and the like.
[0011]
Therefore, an object of the present invention is to solve the above-described disadvantages of the related art.
[0012]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention basically makes a casing having walls on both sides of a striker, and a housing for accommodating a pole and a latch, engage with each other when the luggage panel is closed. Use technical measures.
The adoption of this means makes the luggage panel's rotation locus constant during the opening and closing operation of the luggage panel, prevents the luggage panel from moving in the front-rear direction, and engages the casing and the housing with the luggage panel. It functions to suppress the application of the twisting force.
[0013]
Specifically, the present invention relates to a lock device having at least a latch and a striker, and enabling the luggage panel to be opened and closed with respect to the body while maintaining the engagement between the latch and the striker.
