[Action]

 Due to the above, when the lid is closed, for example, when a part of the human body is sandwiched between the front edge of the lid and the front edge of the roof opening, the connecting means is separated due to the resistance of the human body, and the driven shoe is connected to it. Only the drive shoe slides in the closing direction (forward) with the lid left behind, which can properly prevent injury and improve safety, and drive after the coupling means is disconnected. By sliding the shoe in the opening direction (rearward), the connecting means returns to the original connected state, and the subsequent lid opening / closing operation can be performed normally.

[0007]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 is a roof of an automobile, 2 is a lid for opening and closing an opening 1a of the roof 1, and left and right guide rails 3 are provided at lower portions of both left and right sides of the roof opening 1a. , 3 are mounted in the front-rear direction, and the lid 2 is guided by the left and right guide rails 3, 3 through the left and right guide mechanisms, and slides back and forth between the front end fully closed position and the rear end fully open position. However, since the left and right guide rails and the left and right guide mechanisms are symmetrical and structurally identical, only the guide rail 3 on one side and the guide mechanism on one side are shown in FIG. In (A), the fully opened state of the glass lid 2 is shown.

Basically, the above-mentioned guide mechanism is provided with a drive shoe 4 that slides back and forth in the guide portion 31 of the guide rail 3 by rotational drive of a drive motor (not shown), and a slide movement of the drive shoe 4. A driven shoe 5 (composed of a front driven shoe 51, a rear driven shoe 52, and a connecting member (not shown) integrally connecting them) that slides back and forth in the guide portion 31 of the guide rail 3 together with the driven shoe 5. It comprises a front side link 6 and a rear side link 7 for connecting the shoe 5 and the lid 2, and a connecting means for connecting the drive shoe 4 and the driven shoe 5. A slide member 10 is mounted on the rear portion of the driven shoe 5 (rear driven shoe 52) so as to be freely slidable in the front-back direction of a predetermined stroke range.

As shown in FIG. 2, the connecting means has a hook shape having a pin portion 4a protruding upward from the upper surface of the drive shoe 4 and an engaging recess 8a with which the pin portion 4a engages. The rear portion of the front driven shoe 51 is pivotally attached to the front end portion of the front driven shoe 51 so as to be pivotable in the left-right direction, and the connecting piece 8 engages with the pin portion 4a (see FIG. 2). And a spring 9 that urges it in a clockwise direction. The front side edge portion 8b of the engaging recess 8a of the connecting piece 8 has a force greater than a predetermined value of the driven shoe 5 with respect to the driven shoe 5 in a state where the pin portion 4a is engaged with the engaging recess 8a. When the pin 4a moves forward, the pin 4a overcomes the biasing force of the spring 9 to rotate the connecting piece 8 counterclockwise in FIG. It is built. Further, the front edge 8c of the connecting piece 8 moves the drive shoe 4 rearward with respect to the driven shoe 5 in a state where the pin portion 4a is pulled out forward from the engaging recessed portion 8a, and the pin portion 4a moves forward. When is pressed, the pin portion 4a has a predetermined inclination angle so as to overcome the biasing force of the spring 9 and rotate the connecting piece 8 in the counterclockwise direction in FIG. 2 to engage with the engaging recessed portion 8a. It has a different structure.

The front side link 6 is pivotally attached to the front end portion of a lid frame 21 provided at the lower portion of the side edge of the lid 2 so that the front end thereof is rotatable in the vertical direction, and pins 6 a and 6 a provided at the central portion and the rear portion are provided. The front driven shoe 51 and the front portion of the lid 2 are connected to each other by slidably and rotatably fitted in the front and rear guide groove portions 51a and 51b of the front driven shoe 51, respectively. The rear side link 7 has its front end pivotally attached to a portion slightly rearward of the lid frame 21 so as to be vertically rotatable, has a roller 7c at its rear end, and has two intermediate front and rear pins 7a and 7b. The rear driven shoe 52 and the rear portion of the lid 2 are connected by being slidably and rotatably fitted in the groove portion 52a of the rear driven shoe 52 and the guide groove portion 10a of the slide member 10, respectively. . An arm portion 22 projects forward from the front end portion of the lid frame 21, and a roller 23 provided at the front end of the arm portion 22 is fitted in a roller guide portion 33 of the guide rail 3. The roller guide portion 33 is bent upward at the front end.

Reference numeral 11 denotes a drive wire, which is driven by a drive motor (including a speed reducer) (not shown) in the longitudinal direction to slide the drive shoe 4 connected to the drive wire 11 back and forth, It is slidably fitted in the wire guide portion 32 of the rail 3.

In the above description, when the motor rotates in one direction from the fully open state of FIG. 1A and the drive wire 11 slides forward in the wire guide portion 32, the drive shoe 4 connected to the drive wire 11 Slides forward and the pin portion 4a of the drive shoe 4 engages with the engaging recess 8a of the connecting piece 8 so that the driven shoe 5 is pulled by the drive shoe 4 and slides forward together. Then, the lid 2 is moved forward through the front link 6 and the rear link 7. When the roller 23 reaches the front end of the roller guide portion 33, the forward movement of the lid 2 is stopped by hitting the upward bending portion of the front end of the roller guide portion 33, and from this state, the drive shoe 4 and the driven shoe 5 are stopped. By sliding further forward, the two pins 6a, 6b of the front side link 6 slide relatively backward in the guide groove portions 51a, 51b, and the pins 7a, 7b of the rear side link 7 also have the groove portion 52a. And the guide groove 10a is slid relatively rearward, and the front link 6 and the rear link 7 are rotated upward about the pins 6b and 7b due to the inclination of the guide groove 51a and the groove 52a. The lid 2 is lifted up to the same height as the roof 1 (the roller 23 moves upward in the upward bending portion of the front end of the roller guide portion 33), and the weather strip provided on the periphery of the lid 2 is lifted. 2a is fully closed in elastic contact with the peripheral edge of the roof opening 1a, the closing operation of the lid is completed.

In this fully closed state, the pins 6a and 6b of the front link 6 are located near the center of the guide grooves 51a and 51b in the front-rear direction, and the slide member 10 is moved rearward relative to the rear driven shoe 52. The position is slid to the end, the pin 7a of the rear link 7 is located in the horizontal portion of the groove 52a, 7b is located near the front end of the guide groove 10a, and the roller 7c at the rear end is the rear driven shoe 52. It is located on the first guide surface 52b provided at the rear part of the vehicle.

When the drive motor further rotates in the lid closing operation direction from this fully closed state and the drive shoe 4 slides forward and the driven shoe 5 also slides forward together, the lid 2 cannot move forward, so the front link The pins 6a and 6b of 6 move relatively rearward in the guide grooves 51a and 51b, and the pin 7a of the rear link 7 comes out rearward from the horizontal portion of the groove 52a and the pin 7b is the rear end of the guide groove 10a. And the roller 7c rolls downward on the second guide surface 52c provided on the rear end surface of the rear driven shoe 52, the rear link 7 pivots upward about the pin 7b and the lid 2 moves. The rear part is lifted up and tilted up. When the drive motor rotates in the opposite direction from this tilt-up state, the rear link 7 rotates downward and the rear portion of the lid 2 is lowered downward to return to the original fully closed state.

When the drive motor rotates in the closing operation direction from the fully closed state and the drive shoe 4 slides backward and the driven shoe 5 also slides backward with it, the lid 2 is initially restrained from moving, The pins 6a and 6b of the front side link 6 slide relatively forward in the guide groove portions 51a and 51b, and the front side link 6 rotates downward about the pin 6b due to the inclination of the front end of the front side guide groove portion 51a, and the rear side The pin 7a of the link 7 slides relatively forward in the groove 52a, and the inclination of the groove 52a causes the rear side link 7 to pivot downward about the pin 7b so that the pin 7b moves relatively forward. Therefore, the slide member 10 slides to the front end with respect to the rear driven shoe 52, and the roller 7c is positioned on the guide surface 10b of the slide member 10, and the front side link 6 and the rear side lever 6c. When the link 7 is rotated downward, the lid 2 is lowered downward, the roller 23 is lowered to the lower end of the bent portion of the roller guide portion 33, and the lid 2 can be moved rearward, that is, the state shown in FIG. 1 (A). After that, by sliding the drive shoe 4 and the driven shoe 5 rearward, the lid 2 is moved to the lower portion of the roof 1 behind the opening 1a to be in a fully opened state, and the opening operation of the lid 2 is completed.

In the above description, when the lid 2 is closed, for example, a part of the human body is sandwiched between the front end of the lid 2 and the front edge of the roof opening 1a, whereby the forward movement of the lid 2 is restrained. Then, the forward slide of the driven shoe 5 is also restrained via the front side link 6 and the rear side link 7, so that the pin portion 4a of the drive shoe 4 is engaged with the front edge portion 8b of the engaging recess 8a of the connecting piece 8. Is pressed to overcome the urging force of the spring 9, and the connecting piece 8 is rotated to come out of the engaging concave portion 8a, and the driven shoe 5 is left behind and only the drive shoe 4 slides to the front fully closed position and stops. When pinched in this way, the drive shoe 4 and the driven shoe 5 are disconnected from each other, and the driven shoe 5 and the lid 2 are left behind, so that the injury due to the pinching can be properly prevented.

When the connection between the drive shoe 4 and the driven shoe 5 is disconnected in this way, the drive shoe 4 is opened again. Then, the pin portion 4a of the drive shoe 4 is stopped while the drive shoe 4 is sliding rearward, and hits the front edge 8c of the connecting piece 8 at the front end of the driven shoe 5 to press it to rotate the connecting piece 8. After engaging with the engaging recess 8a, the driven shoe 5 and the lid 2 are slid to the fully open position and stopped, and the driving shoe 4 is closed again to be in the fully closed state.

The risk of pinching during the lid closing operation is within a predetermined range near the fully closed position, and the connecting piece 8 rotates from the fully open position to the predetermined range where there is the risk of pinching (see FIG. 2). It is desirable that the guide rail 3 be provided with a rotation restricting member 12 that restricts counterclockwise rotation.

The inclination angle of the front side edge portion 8b of the engaging recess 8a of the connecting piece 8 and the biasing force of the spring 9 are always determined by the operating resistance during normal operation such as opening and closing of the lid and tilt-up operation. The portion 4a does not slip out of the engaging recess 8a, and is set to an appropriate value so that the pin 4a slips out of the engaging recess 8a as easily as possible when something is sandwiched. The inclination angle of the front edge 8c of the connecting piece 8 is stopped before the driven shoe 5 and the lid 2 start to move, and the connecting piece 8 is rotated by hitting the pin portion 4a so that the pin portion 4a is engaged. It is set as steep as possible so as to engage with the recess 8a.

The mechanism for lifting or lowering the lid 2, that is, the specific configuration of the front link 6, the rear link 7, and the driven shoe 5 in the configuration of the above embodiment is not limited to the illustrated embodiment, The idea is to use any of the conventionally known slide roof devices in which a driven shoe that slides with a drive shoe and a lid are connected via a flap mechanism that raises and lowers the lid, and the lid is opened and closed by a slide before and after the drive shoe. It is applicable.

[0022]

[Effect of device]

In a slide roof device including a flap mechanism that connects the lid and the lid and opens and closes the lid according to the sliding of the driven shoe, the drive shoe and the driven shoe are closed in the closing direction of the drive shoe when the driven shoe is closed. When the directional slide receives a resistance load of a predetermined value or more, it disengages, and after the disengagement, the drive shoe and the driven shoe are connected again by the connecting means configured by the opening slide operation of the drive shoe. As a result, if a part of the human body is caught between the front edge of the lid and the front edge of the roof opening when the lid is closed, the The drive shoe and the driven shoe are disengaged by this, and the driven shoe is left behind, and only the drive shoe slides to the fully closed position and stops, so injury can be accurately prevented and safety can be improved. At the same time, after the connecting means is disengaged as described above, by sliding the drive shoe in the opening direction, the connecting means can easily return to the original connected state, and the subsequent lid opening / closing operation can be performed normally. Therefore, in combination with the simple structure and the low cost, it can bring a great effect in practical use.
