In the roof lock device 10, the base 20 is positioned by two positioning pins 25, 25 with respect to the frame 5 provided inside the front end portion of the roof member 4, and the four mounting holes 24a, 24b, 24c, 24d are provided. Each is fixed to the roof member 4 by being fixed with screws.

  6 is a right side view of the roof lock device shown in FIG. 5, and FIG. 7 is a view showing the roof lock device shown in FIG. 6 except for the side portion of the operation lever cover. 6 and 7, the right side is the front. As shown in FIG. 6, a safety hook base 26 formed by, for example, bending a metal plate is fixed to the attachment portion 21 b of the base 20. A safety hook 28 is rotatably supported on the safety hook base 26 by a support pin 27. The safety hook 28 is formed by bending a metal plate, for example, and has an operation portion 28a that protrudes to the right. Further, the safety hook 28 is biased in a counterclockwise direction in FIG. 6 (that is, a direction in which the operation portion 28a of the safety hook 28 is pushed downward) by a torsion spring 29 provided around the support pin 27. . Furthermore, the safety hook 28 has a hook-shaped hook portion 28b at its lower end.

  As shown in FIGS. 6 and 7, the hook portion 28 b of the safety hook 28 is hooked on the first engagement receiving portion 18 a that is formed integrally with the operation lever member 18 constituting the operation lever 13 and protrudes to the right. It is designed to engage. Thus, when the hook portion 28b of the safety hook 28 is engaged with the first engagement receiving portion 18a of the operation lever 13, the operation lever 13 cannot be rotated. Therefore, the safety hook 28 and the first engagement receiving portion 18a constitute a lock mechanism that restricts the rotation operation of the operation lever 13 to the unlock side.

  As shown in FIG. 4, the operation portion 28 a of the safety hook 28 is in contact with the upper portion of the safety button 15 provided on the cover 11 by the urging force of the torsion spring 29. For this reason, when the safety button 15 is pushed in, the operation portion 28 a of the safety hook 28 is pushed up, and the safety hook 28 rotates against the urging force of the torsion spring 29. As a result, as shown by a dotted line in FIG. 7, the hook portion 28 b of the safety hook 28 is released from the first engagement receiving portion 18 a of the operation lever 13 to be disengaged, and as a result, the rotation operation of the operation lever 13 is performed. It is allowed.

  The operation lever member 18 of the operation lever 13 is rotatably connected to the side wall portions 22a and 22b of the base 20 by two pins 30 at the rear portion thereof. Thereby, the operation lever 13 can be rotated in the front-rear direction around the pin 30.

  A link plate pin 31 is installed at the rear end of the operation lever member 18. As shown in FIG. 8, a pair of link plates 32 made of, for example, a metal plate are rotatably connected to the link plate pins 31. The link plate 32 extends forward in parallel with each other on the inner side of the side wall portions 22 a and 22 b of the base 20.

  A slide pin 33 extends through each front end portion of the pair of link plates 32. As shown in FIG. 10, which is a left side view of the roof lock device 10, both ends of the slide pin 33 are engaged with guide grooves 34 formed in the side wall portions 22 a and 22 b of the base 20. The guide groove 34 has a substantially L shape including a lateral groove 34a and a vertical groove 34b. The slide pin 33 is slidable in the front-rear direction within the lateral groove 34 a of the guide groove 34.

  As shown in FIG. 8, a pair of hook members 35 made of, for example, a metal plate are provided so as to sandwich the pair of link plates 32. Long holes 35a extending in the front-rear direction are formed in the rear portions of the hook members 35, and the slide pins 33 extend through the long holes 35a.

  Further, as shown in FIGS. 6, 7, and 10, the front end portions of the hook members 35 are respectively formed as hook-shaped hook portions 37, and these hook portions 37 are mutually connected by, for example, a resin hook cap 38. Covered to be connected.

  As shown in FIG. 8, guide pins 36 are disposed in front of the slide pins 33 in parallel. The guide pins 36 pass through the long holes 35a formed in the respective hook members 35, and as shown in FIG. 10, both ends thereof engage with the guide grooves 34 formed in the side wall portions 22a and 22b of the base 20, respectively. is doing. Thereby, the guide pin 36 is slidable along the guide groove 34.

  The pair of hook members 35 are also connected by a hook pin 39 that penetrates in the vicinity of the hook portion 37 at the front end thereof. The hook pin 39 extends so that the hook pin 39 protrudes outward from the left side surface of one hook member 35, and one end of the tension coil spring 40 is hooked on the tip portion. The other end of the tension coil spring 40 is hooked on a protrusion 21 c formed on the attachment portion 21 a of the base 20.

  A first guide plate 41 is disposed between the front end portions of the pair of link plates 32. A second guide plate 42 is disposed between the pair of hook members 35. The first guide plate 41 and the second guide plate 42 are connected to each other by the male screw portion protruding from the first guide plate 41 being screwed into the female screw portion of the second guide plate 42. The slide pin 33 and the guide pin 36 pass through the first guide plate 41, respectively. The hook pin 39 penetrates through the second guide plate 42. Thus, the hook member 35 is rotatable with respect to the link plate 32 around the slide pin 33 that penetrates the pair of link plates 32.

  As shown in FIG. 11, which is a cross-sectional view of the roof lock device of FIG. 10, a handle hook 44 projects from the back surface of the operation lever 13. The handle hook 44 is made of, for example, a metal leaf spring that can be elastically deformed, and is fixed to the operation lever member 18. The handle hook 44 has an engaging portion 45 that protrudes forward in a triangular shape at the tip. As shown in FIG. 12, the engagement portion 45 of the handle hook 44 is connected to the base 20 when the operation lever 13 is slightly rotated downward about the pin 30 to be in a state indicated by a two-dot chain line. The positional relationship is such that the rear end edge of the portion 23 can be engaged.

  When the operating lever 13 is rotated downward with the engaging portion 45 of the handle hook 44 engaged with the rear end edge of the connecting portion 23 of the base 20, the handle hook 44 is elastically deformed so as to bend backward. Thus, the engagement between the engaging portion 45 and the rear end edge portion of the connecting portion 23 of the base 20 is released. Further, a hook protection wall 46 is attached to the operation lever member 18 on the rear side of the handle hook 44 in order to prevent the handle hook 44 from being deformed rearward to such an extent that the handle hook 44 cannot elastically return to the original state. It has been.

Next, the operation of the roof lock device 10 having the above configuration will be described.
In the roof lock device 10, when the operation lever 13 is in the state shown in FIG. 7, the hook portion 37 is engaged with the striker 8 on the vehicle body side, so that the roof member 4 is restricted from moving backward. It is in. Further, in this locked state, the hook portion 28b of the safety hook 28 is engaged with the first engagement receiving portion 18a of the operation lever member 18, so that the rotation of the operation lever 13 to the unlock side is restricted. Has been.

  When the operator performs the unlocking operation of the roof member 4 in the locked state, the operator grasps the front end portion 14 of the operation lever 13 with a finger other than the thumb of the right hand and presses the safety button 15 with the same thumb of the right hand. Operate and push up. Then, when the safety button 15 is pushed in, the safety hook 28 rotates in the clockwise direction in FIG. 7 against the urging force of the torsion spring 29, whereby the hook portion 28 b of the safety hook 28 is moved to the operation lever member 18. The first engagement receiving portion 18a is disengaged and released, and as a result, the rotation restriction of the operation lever 13 by the safety hook 28 is released.

  Although the operation lever 13 is rotated downward by its own weight due to the release of the rotation restriction of the safety hook 28, the engaging portion 45 of the handle hook 44 provided on the back surface of the operation lever 13 is connected to the base 20 as shown in FIG. By engaging the rear end edge of the portion 23, the operation lever 13 is again restricted from rotating at a predetermined rotation position. In this state, the operation lever 13 is held at the predetermined rotation position by the handle hook 44 as long as the operator does not perform the rotation operation so as to pull the operation lever 13 downward.

  When the operation lever 13 is in the predetermined rotation position, the tip of the hook portion 28b of the safety hook 28 comes into contact with the side surface of the first engagement receiving portion 18a, so that the hook portion 28b becomes the first engagement receiving portion. It is in the state which cannot be engaged with 18a. Therefore, regardless of the urging force of the torsion spring 29, the safety hook 28 is held in a state where the safety hook 15 is rotated in the clockwise direction when the safety button 15 is pushed. Since the operation portion 28a of the safety hook 28 thus held does not press the safety button 15 downward, the safety button 15 remains pushed into the cover 11 by the urging force of the coil spring 17, and the safety button 15 For example, the red mark portion 16 provided on the side wall of the 15 accommodation space is exposed. In this way, the safety button 15 remains in the retracted state and the red mark portion 16 is exposed, so that the operator visually confirms that the rotation restriction of the operation lever 13 by the safety hook 28 is released. Can be easily confirmed.

  From the state in which the lock by the safety hook 28 is released and the operation lever 13 is held at the predetermined rotation position by the handle hook 44 or immediately after the safety button 15 is pushed in, the operator presses the operation lever 13. When turning to the unlock side, the triangular engaging portion 45 of the handle hook 44 is pushed by the rear end edge of the connecting portion 23 of the base 20, so that the handle hook 44 is elastically deformed backward and bent. Thereby, the engagement between the engaging portion 45 of the handle hook 44 and the rear end edge portion of the connecting portion 23 of the base 20 is released, and the rotation restriction of the operation lever 13 by the handle hook 44 is released.

  After the restriction of the rotation of the operation lever 13 by the handle hook 44 is released, when the operator further rotates the operation lever 13 to the unlock side, the link plate is moved with respect to the pin 30 that is the rotation center of the operation lever 13. As the pin 31 moves forward, the hook member 35 moves forward via the link plate 32. The forward movement of the link plate 32 and the hook member 35 at this time is guided by the slide pin 33 and the guide pin 36 moving along the lateral groove 34 a of the guide groove 34 formed in the side wall portions 22 a and 22 b of the base 20. The As the hook member 35 moves forward in this manner, the hook portion 37 moves away from the striker 8 forward.

  Then, as shown in FIG. 13, when the operation lever 13 is further rotated to the unlock side, which is the rear side of the vehicle body, the guide pin 36 is formed in the longitudinal direction of the guide groove 34 formed in the side wall portions 22 a and 22 b of the base 20. The hook member 35 is largely rotated downward about the slide pin 33 by the tensile force of the tension coil spring 40 while entering the groove 34b. As a result, the hook portion 37 of the hook member 35 is completely disengaged from the striker 8 on the vehicle body side to be disengaged, and as a result, the roof member 4 is unlocked and unlocked by the roof lock device 10.

  After the roof lock device 10 is unlocked, if the operator pulls the operation lever 13 backward while holding the operation lever 13, the roof member 4 moves rearward, thereby opening the roof member 4 and storing it. Can be.

  As described above, according to the roof lock device 10 for the open car of the present embodiment, the safety button 15 for releasing the rotation restriction of the operation lever 13 by the safety hook 28 is provided in the vicinity of the side surface of the operation lever 13. Therefore, the distance between the safety button 15 and the front end portion 14 of the operation lever 13 can be shortened, and the operability in one-handed operation can be improved. Further, since the safety button 15 is provided in the vicinity of the side surface that is located away from the rotation axis (pin 30) of the operation lever 13, a finger is pinched between the safety button 15 and the operation lever 13. Also disappear.

  In addition, since the safety button 15 is arranged in a range where the thumb of the hand holding the operation lever 13 can reach, each operation of the safety button 15 and the operation lever 13 can be easily performed with one hand.

  Further, the turning operation direction of the operation lever 13 for disengaging the hook portion 37 of the hook member 35 from the striker 8 is the rear side of the vehicle body, and the safety button is positioned at the right side when viewed from the rear side of the vehicle body with respect to the turning operation direction. 15, while the safety button 15 is pressed with the thumb of the right hand, the operating lever 13 is rotated to the rear side of the vehicle body, and the roof member 4 is moved to the rear side of the vehicle body as it is. A series of opening operations can be performed smoothly.

  Furthermore, the safety button 15 is a push-type button, and the pressing direction (that is, the upper side) at the time of releasing is the direction opposite to the hook member disengagement operating direction (that is, the lower side) of the operating lever 13, so Since the safety button 15 can be pressed while gripping the operation lever 13 as if it is gripped, the rotation restriction of the operation lever 13 can be easily released.

  Furthermore, even if the rotation restriction of the operation lever 13 by the safety hook 28 is released, the rotation of the operation lever 13 is restricted by the handle hook 44, so that the operation lever 13 freely rotates downward by its own weight. Can be prevented. Further, since the restriction of the operation lever 13 by the handle hook 44 is released by the turning operation of the operation lever 13, the operation lever 13 is unexpectedly turned as soon as the restriction by the safety hook 28 is released. There is no sagging state and it is safe for the driver. Furthermore, since the restriction by the handle hook 44 is released simply by rotating the operation lever 13, the release operation does not become complicated.

Next, the lock operation of the roof lock device 10 will be briefly described.
With the roof member 4 mounted so as to close the roof portion 3 of the vehicle body, the operation lever 13 is locked from the position shown in FIG. 13 (that is, the direction opposite to the unlocking side rotation operation direction or the vehicle body front side). As the guide pin 36 is guided along the guide groove 34 of the base 20, the hook member 35 is changed from a substantially vertically open state to a substantially horizontally closed state.

  When the operation lever 13 is further rotated to the lock side, the operation lever member 18 is pulled via the link plate 32, whereby the hook member 35 is moved rearward. At this time, the hook portion 37 of the hook member 35 approaches and engages with the striker 8 on the vehicle body side.

  When the operation lever 13 is turned to the lock side until the handle hook 44 comes into contact with the rear end edge of the connecting portion 23 of the base 20, the operation hook 13 is pushed upward so that the handle hook 44 elastically moves backward. By being deformed and bent, the engaging portion 45 of the handle hook 44 gets over the rear end edge portion of the connecting portion 23 of the base 20.

  At substantially the same time as the engaging portion 45 of the handle hook 44 gets over the rear end edge of the connecting portion 23 of the base 20, the lower inclined surface of the hook portion 28 b of the safety hook 28 receives the first engagement receiving of the operating lever member 18. The safety hook 28 rotates in the clockwise direction in FIG. 7 against the urging force of the torsion spring 29 by coming into contact with the portion 18a, and as a result, when the operating lever 13 is completely returned to the locked position, 28 is rotated counterclockwise in FIG. 7 by the biasing force of the torsion spring 29, and the hook portion 28 b of the safety hook 28 is engaged with the first engagement receiving portion 18 a of the operation lever member 18.

  When the safety hook 28 is engaged with the first engagement receiving portion 18a, the safety button 15 is pushed down against the urging force of the coil spring 17 by the operation portion 28a of the safety hook 28, and the cover 11 Return to the same state. Thereby, the lock operation of the roof lock device 10 is completed.
