[0003] [Patent Document 1] JP 2019-64369 A Summary of the Invention [Problem to be solved by the invention]
[0004] In the above-mentioned sliding door device, the hook member is not engaged with the locking member unless the pressing member provided on the sliding door is displaced from the inside to the outside of the vehicle. Therefore, depending on the location where the sliding door is pushed, the hook member may not operate, and the displacement of the sliding door from the inside to the outside of the vehicle may not be restricted.
[0005] A main object of the sliding door device of the present disclosure is to provide a sliding door device that can more reliably suppress displacement of the sliding door from the inside of the vehicle to the outside of the vehicle. [Means for solving the problem]
[0006] The sliding door device of the present disclosure employs the following means to achieve the above-mentioned main object.
[0007] The sliding door device of the present disclosure is A sliding door device including a sliding door that opens and closes a door opening formed on a side surface of a vehicle body by sliding in the front-rear direction of the vehicle body, A striker fixed to an edge portion of the door opening; a first latch that is fixed to an end portion of the sliding door that faces the opening edge portion when the sliding door is fully closed, and that is pressed by the striker to rotate when the sliding door is fully closed, and that is capable of engaging with a leg portion of the striker in a direction from the vehicle interior to the vehicle exterior; The gist of the present invention is as follows.
[0008] The sliding door device disclosed herein includes a first latch that is pressed by the striker to rotate when the sliding door is fully closed and can engage with the leg of the striker in a direction from the inside to the outside of the vehicle. Since the first latch is automatically in a state where it can engage with the striker when the sliding door is fully closed, it is possible to more reliably suppress the displacement (opening) of the sliding door from the inside to the outside of the vehicle. As a result, the safety of the occupants can be ensured. [Brief description of the drawings]

[0012] The sliding door device 10 of this embodiment opens and closes a door opening 3 formed on a side surface of a vehicle body 2 by sliding a pair of front and rear sliding doors 11, 12 toward and away from each other with respect to the door opening 3. As shown in FIG. 1 , the sliding door device 10 includes a striker 14, a fully closed locking device 15, a striker 16, a fully open locking device 20, and an upper hook device 30 in addition to the pair of front and rear sliding doors 11, 12.
[0013] As shown in Fig. 1, rails 5 extending in the front-rear direction are provided on the upper and lower edges of the front half of the door opening 3, and rail 6 extending forward from the vertical middle is provided on the front edge of the door opening 3. In the front sliding door 11, rollers R are provided via support members 13 on the upper and lower parts of the rear end side as shown in Figs. 2 and 3, and roller R (not shown) is provided via a support member on the vertical middle part of the front end side. The rollers R roll on the rails 5, 6 to allow the sliding door 11 to slide forward and backward.
[0014] Further, rails 5 extending in the front-rear direction are provided on the upper and lower edges of the rear half of the door opening 3, and rail 6 extending rearward from the vertical middle part is provided on the rear edge of the door opening 3. Rollers R (not shown) are provided via support members on the upper and lower parts of the front end of the rear sliding door 12, and rollers R (not shown) are provided via support members on the vertical middle part of the rear end. The rollers R roll on the rails 5, 6, causing the sliding door 12 to slide forward and backward.
[0015] The striker 14 is fixed to one of the opposing surfaces of the pair of front and rear sliding doors 11, 12.
[0016] The full-close lock device 15 is provided on the other of the opposing surfaces of the pair of front and rear sliding doors 11, 12, and connects and locks the sliding doors 11, 12 when the sliding doors 11, 12 are fully closed. Although not shown, the full-close lock device 15 includes a latch engageable with the striker 14, a pole that engages with the latch to restrict the rotation of the latch, and a release lever for releasing the engagement between the latch and the pole.
[0017] A full-open locking device 20 is provided on each of the sliding doors 11, 12. One full-open locking device 20 is provided on the upper and rear end side of the front sliding door 11, and the other full-open locking device 20 is provided on the upper and front end side of the rear sliding door 12. When the sliding doors 11, 12 are fully open, each full-open locking device 20 engages with a corresponding one of two strikers 16 fixed to both ends in the front-rear direction of the upper edge of the door opening 3, thereby locking the sliding doors 11, 12 in the fully open state.
[0018] The two strikers 16 each include a base member 17 fixed to the vehicle body 2 and a striker body 18 supported by the base member 17. As shown in FIG. 8, the striker body 18 is a substantially U-shaped member having a pair of legs 18a, 18b extending parallel to each other and a connecting portion 18c connecting the tips of the pair of legs 18a, 18b. The base ends of the pair of legs 18a, 18b are fixed to the base member 17. A notch 19 is formed on the side surface of the leg 18b facing the vehicle interior. Each striker 16 is fixed to the upper edge of the door opening 3 so that the pair of legs 18a, 18b extend in the vertical direction and are aligned in the direction from the vehicle interior to the vehicle exterior.
[0019] 2 and 4, the full-open lock device 20 includes a base member 28 fixed to the support member 13 of the sliding door 11, a latch 21 rotatable with respect to the base member 28 and engageable with the striker 16 when the sliding door 11 is fully open, a pole 22 rotatable with respect to the base member 28 and engaging with the latch 21 to restrict the rotation of the latch 21, and a release lever 23 for releasing the engagement between the latch 21 and the pole 22. The latch 21 extends at a distance slightly wider than the outer diameter of the leg 18a of the striker 16 and has two hook portions 21a, 21b that sandwich and engage with the leg 18a. The latch 21 is biased clockwise in the drawing by a spring, and when the sliding doors 11, 12 are fully opened, the leg 18a of the striker 16 presses one of the hook portions 21a, causing the latch 21 to rotate counterclockwise. Then, by further rotating the latch 21 counterclockwise so that the pole 22 engages with the latch 21, the leg 18a of the striker 16 is sandwiched between the two hook portions 21a, 21b, and the sliding doors 11, 12 are locked in the fully open state.
[0020] An upper hook device 30 is provided on each of the sliding doors 11, 12. One upper hook device 30 is provided on the upper part and front end side of the front sliding door 11 (the end opposite to the end where one full-open lock device 20 is provided in the front-rear direction), and the other upper hook device 30 is provided on the upper part and rear end side of the rear sliding door 12 (the end opposite to the end where the other full-open lock device 20 is provided in the front-rear direction). When the sliding doors 11, 12 are fully closed, each upper hook device 30 engages with a corresponding one of the two strikers 16 described above, thereby restricting the displacement of the sliding doors 11, 12 from the inside to the outside of the vehicle.
[0021] 5 to 7, the upper hook device 30 includes a base member 38, a latch 31 that is rotatable relative to the base member 38 and that is engageable with the striker 16 when the sliding doors 11, 12 are fully closed, a pole 32 that is rotatable relative to the base member 38 and that engages with the latch 31 to restrict the rotation of the latch 31, and a release lever 35 that releases the engagement between the pole 32 and the latch 31. In this embodiment, the striker 16 with which the latch 31 of the upper hook device 30 is engaged is shared with the striker 16 with which the latch 21 of the above-mentioned full-open lock device 20 is engaged. This allows the number of parts to be reduced, thereby further reducing costs.
[0022] 5 and 6, the latch 31 has a rotation axis A1 that extends in the vertical direction of the vehicle body 2 and is rotatably supported by a base member 38, and two hook portions 31a, 31b that extend with a distance greater than the distance between the pair of legs 18a, 18b of the striker 16 and are bent so that their tips are close to each other. That is, the latch 31 is formed in a substantially C-shape when viewed from the direction of the rotation axis A1. A spring 33 is provided on the rotation axis A1 of the latch 31, and the latch 31 is biased by the spring 33 in the clockwise direction in the drawings.
[0023] 5 and 6, the pole 32 has a rotation axis A2 that extends parallel to the rotation axis A1 and is rotatably supported by a base member 38, a latch engagement portion 32a that engages with one hook portion 31a of the latch 31, and a release lever engagement portion 32b that engages with the release lever 35. A spring 34 is provided on the rotation axis A2 of the pole 32, and the pole 32 is biased by the spring 34 in the counterclockwise direction in the drawings.
[0024] As shown in FIG. 7, the release lever 35 has a rotation axis A3 that extends in a direction perpendicular to the rotation axes A1 and A2 and is rotatably supported by a base member 38, and a pole engagement portion 35a that engages with the release lever engagement portion 32b of the pole 32. A spring is provided on the rotation axis A3 of the release lever 35, and the release lever 35 is biased clockwise in the figure by the spring. When the release cable 36 is pulled by a motor (not shown) while the latch 31 and the pole 32 are engaged with each other, the release lever 35 rotates counterclockwise in FIG. 7. When the release lever 35 rotates counterclockwise, the pole 32 rotates clockwise in FIG. 6. This releases the engagement between the latch 31 and the pole 32.
[0025] In the upper hook device 30 thus configured, when the sliding doors 11, 12 are fully closed, first, one hook portion 31a of the latch 31 on the vehicle exterior side comes into contact with one leg portion 18a of the striker 16 (striker body 18) on the vehicle exterior side (see FIG. 9(a)). When the sliding doors 11, 12 slide further in the closing direction, one hook portion 31a of the latch 31 is pressed by one leg portion 18a of the striker 16, and the latch 31 rotates counterclockwise in the figure (see FIG. 9(b)). When the latch 31 rotates, the other hook portion 31b of the latch 31 on the vehicle interior side turns around to the other leg portion 18b of the striker 16 on the vehicle interior side, and one hook portion 31a of the latch 31 engages with the latch engagement portion 32a of the pole 32 (see FIG. 9(c)). Then, the sliding doors 11, 12 are fully closed in a state where the other hook portion 31b has wrapped around to the other leg portion 18b of the striker 16 (see FIG. 9(d)). As a result, even if the sliding doors 11, 12 are pressed from the inside to the outside of the vehicle, the other hook portion 31b engages with the other leg portion 18b of the striker 16, and the displacement of the sliding doors 11, 12 toward the outside of the vehicle is restricted. In this way, when the sliding doors 11, 12 are fully closed, the latch 31 automatically wraps around to the inside of the vehicle of the striker 16 and becomes capable of engaging with the striker 16, so that the displacement of the sliding doors 11, 12 from the inside to the outside of the vehicle can be restricted more reliably. As a result, the safety of the occupants can be ensured. In addition, as shown in FIG. 8, a notch 19 is formed in the other leg portion 18b on the vehicle interior side of the striker 16. Therefore, when the sliding doors 11, 12 are displaced from the vehicle interior side to the vehicle exterior side and the other hook portion 31b comes into contact with the other leg portion 18b, the other hook portion 31b engages with the notch 19 as shown in FIG. 8, thereby preventing misalignment of the engagement and more reliably preventing the sliding doors 11, 12 from being displaced from the vehicle interior side to the vehicle exterior side.
[0026] In the above-described embodiment, the sliding doors 11, 12 are provided in a pair at the front and rear and slide toward and away from each other on the vehicle body 2 to open and close the door opening 3. However, the sliding door may be a single sliding door that slides rearward relative to the door opening 3 to open and close the door opening 3.
[0027] In the above-described embodiment, the full-open lock device 20 and the upper hook device 30 are installed at the upper part of the sliding doors 11, 12, but they may be installed at the lower part of the sliding doors 11, 12.
[0028] In the above-described embodiment, the latch 21 of the full-open lock device 20 and the latch 31 of the upper hook device 30 are engaged with the same striker 16, but they may be engaged with different strikers.
[0029] The above describes the form for implementing the present disclosure using embodiments, but the present disclosure is not limited to these embodiments in any way, and it goes without saying that the present disclosure can be implemented in various forms without departing from the gist of the present disclosure. [Industrial Applicability]
