  In view of the above problems, it is an object of the present invention to provide a roof lock device that is easy to attach and detach, but that cannot be accidentally unlocked.

In order to solve the above-described problem, a roof lock device according to the present invention includes a handle that is pivotally supported at one end on a base fixed to a roof member and whose other end approaches or separates from the base. A hook member that is pivotally supported by the handle and can be rotated in the same direction as the rotation direction of the handle , and the handle rotates in a direction away from the base and engages with a striker fixed to the vehicle body. And a biasing member that biases the hook member in a direction to engage the striker, and an engagement receiving portion provided on the base when the handle is close to the base and protrudes from the hook member. The hook member can be turned against the urging force of the urging member, and when the handle is separated from the base, the engagement receiving portion cannot be engaged. Has a proper engaging part And things.

  According to this configuration, the engaging portion can be moved only by rotating the handle away from the base from the state where the engaging portion engages with the engaging receiving portion and restricts the rotation of the hook member. The hook member is released from the engagement receiving portion and is rotated in a direction to engage the striker by the urging member. When the handle is rotated so as to approach the base, the roof lock device is locked to the striker. Thus, the roof member can be reliably fixed to the vehicle body by a simple operation. Particularly, when the handle is moved away from the base, the hook member is automatically inserted into the hook hole of the striker by the urging force of the urging member, so that the hook member is held in the inserted state with respect to the hook hole. This eliminates the need for the operator to move the handle close to the base, and enables the hook member to be securely engaged with the striker. When the hook member is not actually engaged with the striker, the roof member is erroneously recognized as being locked. Opening and falling off can be prevented.

  Further, in the roof lock device of the present invention, the hook member is pivotally supported by the handle and rotated in a direction away from the base so as to come into contact with an interlocking protrusion provided on the hook member so that the hook member is separated from the striker. You may have a lever which has an interlocking part rotated in the direction to do.

  According to this configuration, if the handle is moved closer to the base while the handle is moved away from the base and the hook member is rotated against the biasing force of the biasing member by the lever, the engaging portion of the hook member is received. The roof member can be easily fixed.

  In the roof lock device of the present invention, the interlocking portion and the interlocking projecting piece rotate the lever when the hook member is in a direction approaching the striker at a predetermined angle or more with respect to the handle. It may be provided so that it does not contact each other even if it moves.

  According to this configuration, the pivoting range of the lever may be a minimum for locking or releasing the engaging portion of the hook member with the engaging receiving portion, and the roof lock device does not become larger than necessary. Further, since the engagement between the hook member and the striker cannot be released unless the handle is rotated more than a predetermined angle, it is possible to prevent the roof lock device from being unlocked due to an erroneous operation.

  In the roof lock device of the present invention, the interlocking portion and the interlocking protrusion may be positioned so as to contact each other when the engaging portion is locked to the engaging receiving portion. Good.

  According to this configuration, when the roof member is fixed, the engagement portion of the hook is separated from the engagement receiving portion by the lever, and friction can be prevented from occurring between the engagement portion and the engagement receiving portion. The roof member can be fixed easily by rotating the handle.

  In the roof lock device of the present invention, when the handle is moved away from the base to the maximum in a state where the striker is in a position to be engaged with the roof lock device, the hook member is moved by the striker to the biasing member. The interlocking portion and the interlocking projecting piece due to the rotation of the lever can be brought into contact with each other, and the striker is in a position to be engaged with the roof lock device. Even if the handle is rotated while holding the lever on the base side with respect to the handle, the interlocking portion and the interlocking protruding piece may not contact each other.

  According to this configuration, when the hook member is engaged with the striker, the interlocking portion can be fully opened in the separating direction without contacting the interlocking projecting piece, and the lever is operated in the fully separating state when the lever is operated in the separating direction. Is brought into contact with the interlocking protrusion, and the handle is rotated while the lever is operated, whereby the hook member is rotated integrally with the handle and the engaging portion is engaged with the engaged portion. For this reason, when removing a roof member, the engaging part of a hook member can be latched so that the next fixing operation | work is possible.

  In the roof lock device of the present invention, the safety mechanism includes a safety mechanism capable of locking the handle in an approaching state with respect to the base, and the lever is rotated in a direction away from the base, whereby the safety mechanism May be released.

  According to this configuration, it is possible to prevent the handle from rotating undesirably, so that there is no unexpected unlocking. Further, as described above, since the pseudo lock is not generated in the roof lock device of the present invention, the structure is not configured to fix the handle by the tension due to the engagement of the hook member, and even if the handle is locked by the safety mechanism, The lock is never overlooked. Further, according to the above configuration, the handle can be rotated and the safety mechanism can be released simultaneously by operating the lever. Therefore, the roof member can be fixed by moving the handle away from the base and then returning the handle. . For this reason, the roof lock device is easy to attach and detach, but cannot be easily removed when not intended.

  In the roof lock device of the present invention, the safety mechanism is pivotally supported by the handle, engageable with a safety shaft provided on the base, and is separated from the safety shaft by rotation of the lever. You may have a hook.

  According to this configuration, unintentional rotation of the handle can be prevented with a simple structure, and the roof member can be easily attached and detached.

  As described above, in the roof lock device of the present invention, the hook member is biased in the direction in which the hook member is engaged with the striker. It will not even drop out. Further, when positioning for fixing the roof member, the hook member can be locked so as to be separated from the striker, so that the positioning of the roof member is not hindered. And it is easy to attach and detach while having such features.

Embodiments of the present invention will now be described with reference to the drawings.
FIG. 1 and FIG. 2 show a side surface and a plane (a state seen from the inside when fixed to a roof member) of a roof lock device 1 according to one embodiment of the present invention. The roof lock device 1 includes a base 2 and a handle 3, and is screwed to an inner side of an end portion of a roof member (not shown) through a mounting hole 4 provided in the base 2. One end of the handle 3 is bifurcated. Each handle 3 is pivotally supported on one end of the base 2 by a handle shaft 5 and is rotatable about the handle shaft 5. The base 2 is provided with a positioning convex portion 6 that further protrudes from an end portion on which the handle 3 is pivotally supported. The handle 3 is provided so as to protrude from an end portion on the opposite side, and a hook member 7 projecting from a pivotally supported end portion and having a distal end bent in a “J” shape toward the positioning convex portion 6. And lever 8.

  Further, FIG. 3 shows a cross section of the roof lock device 1 together with a striker 9 that is fixed to a vehicle body (not shown) of an automobile and engages with the roof lock device 1, and the configuration will be described in detail. The striker 9 is provided with a positioning concave portion 10 into which the positioning convex portion 6 fits at one end and a hook hole 11 that engages with the hook member 7. The hook hole 11 is formed on the inner side surface of the automobile on the roof lock device 1. The side edge protrudes inward to form a locking edge 12. The hook member 7 is pivotally supported on the handle 3 by a hook shaft 13 provided slightly on the rear side of the handle shaft 5 when viewed from the striker 9, and on the striker 9 side with respect to the handle 3 by a hook spring (biasing member) 14. It is biased to rotate. Further, the hook member 7 is provided with an engaging portion 15 that protrudes toward the base 2 and an interlocking protrusion 16 that protrudes toward the handle 3. As shown in the figure, the engaging portion 15 engages with an engaging receiving portion 17 provided on the base 2 to lock the hook member 7 at an angle away from the striker 9 against the urging force of the hook spring 14. Is possible. The lever 8 is pivotally supported on the handle 3 by a lever shaft 18, and has an interlocking portion 19 having one end protruding outside the handle 3 and the other end extending inside the handle 3 toward the hook member 7. Yes. The lever 8 is urged by a lever spring 20 in a direction in which an end protruding from the handle 3 approaches the base 2. The handle 3 has a safety hook 21 that is coaxially supported by the lever 8 and pivotally supported by the lever shaft 18. The safety hook 21 protrudes from the handle 3 toward the base 2 and has a tip projecting in the direction of the handle shaft 5 and can be engaged with a safety shaft 22 provided on the base 2. The safety hook 23 is engaged with the safety hook 21. It has a urging end portion 24 and is urged by the safety spring 23 toward the handle shaft 5 to be engaged with the safety shaft 22 (safety mechanism). When the lever 8 is rotated against the urging force of the lever spring 20, the urging end 24 is pressed by the release protrusion 25 provided on the lever 8, and the safety hook 21 is rotated to detach from the safety shaft 22. Can be made.

Next, an operation (locking operation) for fixing the roof member to the vehicle body by the roof locking device 1 will be described with reference to FIGS.
First, as shown in FIG. 4, the engaging portion 15 of the hook member 7 is engaged with the engaging receiving portion 17 of the base 2, the handle 3 is in close contact with the base 2, and the safety hook 21 is engaged with the safety shaft 22. The positioning convex portion 6 of the roof lock device 1 in a state of being fitted is aligned with the positioning concave portion 10 of the corresponding striker 9 fixed to the vehicle body. Then, as shown in FIG. 5, when the lever 8 is pressed so as to rotate away from the base 2, the release protrusion 25 presses the urging end portion 24 of the safety hook 21, and the safety hook 21 is Release from engagement with the shaft 22. At the same time, the interlocking portion 19 of the lever 8 abuts on the interlocking protrusion 16 of the hook member 7 to slightly rotate the hook member 7 around the hook shaft 13. Thereby, the engaging portion 15 of the hook member 7 is slightly separated from the edge of the engaging receiving portion 17 of the base 2.

  Since the safety hook 21 is detached from the safety shaft 22, when the lever 8 is further pressed, the handle 3 rotates so as to separate from the base 2 around the handle shaft 5 as shown in FIG. 6. As shown in FIG. 7, when the lever 8 is further depressed and the handle 3 is rotated to the maximum opening, the tip of the hook member 7 enters the hook hole 11 of the striker 9, and the hook member 7 The portion abuts against the striker 9 and is further rotated against the urging force of the hook spring 14 around the hook shaft 13.

  Here, as shown in FIG. 8, when the pressing of the lever 8 is interrupted, the lever 8 is returned to the state parallel to the handle 3 by the lever spring 20. Then, as shown in FIG. 9, the handle 3 is rotated so as to approach the base 2. At this time, the tip of the hook member 7 is locked to the locking edge 12 of the hook hole 11 and rotates relative to the handle 3 around the hook shaft 13. Thereby, the interlocking protrusion 16 of the hook member 7 is angled with respect to the lever 8 in the direction of the striker 9, and the distance between the tip of the interlocking protrusion 16 and the lever shaft 18 is increased. Therefore, even if the handle 3 is rotated as it is, the interlocking portion 19 of the lever 8 does not come into contact with the interlocking protrusion 16. The hook shaft 13 that pivotally supports the hook member 7 also rotates around the handle shaft 5 and moves away from the striker 9. Accordingly, the roof lock device 1 itself is attracted to the striker 9 in an attempt to draw the tip of the hook member 7.

  When the handle 3 is further rotated, the tip of the safety hook 21 comes into contact with the safety shaft 22 as shown in FIG. Since the tip of the safety hook 21 has a pressure angle, when the handle 3 is further pressed toward the base 2, the safety hook 21 rotates so as to slide on the safety shaft 22, and finally, As shown in FIG. 12, the handle 3 is closed so as to be in close contact with the base 3, and the safety hook 21 is engaged with the safety shaft 22. In this way, the striker 9 is sandwiched and fixed between the positioning convex portion 6 and the hook member 7. That is, the roof lock device 1 and the roof member are fixed to the vehicle body to which the striker 9 is fixed.

Further, an operation (unlocking operation) of removing the roof lock device 1 from the striker 9 will be described in order with reference to FIGS. 13 to 20.
FIG. 13 shows a state in which the lever 8 is depressed to make the handle 3 pivotable from a state in which the roof lock device 1 is fixed to the striker 9, that is, a state in which a roof member (not shown) is fixed to the vehicle body. A state in which the engagement of the safety hook 21 is released is shown. Further, as shown in FIG. 14, the lever 8 is pressed to rotate the handle 3, and the safety hook 21 is released from the safety shaft 22. Therefore, as shown in FIG. 15, the pressing of the lever 8 is interrupted, and the lever 8 is returned in parallel with the handle 3 by the lever spring 20.

  Then, as shown in FIG. 16, the handle 3 is rotated to the maximum opening without rotating the lever 8 with respect to the handle 3. At this time, the hook member 7 is rotated toward the striker 9 by the hook spring 14, and the interlocking protrusion 16 is at a relatively large angular position from the line connecting the hook shaft 13 and the lever shaft 18. Can move to the striker 9 side of the interlocking protrusion 16 without contacting the interlocking protrusion 16.

  However, as shown in FIG. 17, when the handle 3 has the maximum opening, the interlocking protrusion 16 is substantially on the line connecting the hook shaft 13 and the lever shaft 18, and when the lever 8 is rotated in this state, the interlocking portion 19 abuts on the interlocking protrusion 16. Therefore, when the handle 8 is rotated so as to approach the base 2 while the lever 8 is rotated with respect to the handle 3, the hook member 7 is not rotated by the hook spring 14, as shown in FIG. It rotates with the handle 3 while maintaining the angle with respect to the handle 3. As shown in FIG. 19, when the handle 3 is rotated until it comes into contact with the base 2, the engaging portion 15 of the hook member 7 moves into the engaging receiving portion 17 of the base 2. When the lever 8 is released in this state, the hook 7 is rotated by the hook spring 14, and the engaging portion 15 comes into pressure contact with the edge of the engaging receiving portion 17 as shown in FIG. 20. At the same time, the safety hook 21 is also engaged with the safety shaft 22 and locked so that the handle 3 does not rotate away from the base 2.

  As shown in FIG. 20, the roof lock device 1 with the striker 9 opened returns to the state before being fixed to the striker 9 shown in FIG. Therefore, the roof lock device 1 can be easily fixed to the striker 9 again.

  Thus, the roof lock device 1 can be attached to and detached from the striker 9 with a simple operation. In particular, since the hook member 7 is biased by the hook spring 14 in the direction in which the hook member 7 is engaged with the striker 9, the hook member 7 can surely enter the hook hole 11 and be fixed. Further, even if the handle 3 is undesirably opened away from the base 2, the hook member 7 remains in the hook hole 11 because it is biased by the hook spring 14 as shown in FIG. 16. Therefore, even if the handle 3 is opened while the automobile is running, the roof member is only loose and does not fall off, which is safe.
