Description

  The present invention relates to a vehicle locking device that can be provided on, for example, a vehicle floor and a folding seat that is rotatably supported on the floor.

The folding seat supported rotatably on the vehicle floor includes a lock mechanism that locks the striker protruding from the vehicle floor when the seat is moved to a use position that is parallel to the vehicle floor. .
This type of locking mechanism generally includes a notch groove formed in a base member provided at the bottom of a seat portion, a hook provided rotatably in the base member, and a pole provided rotatably in the base member. It has. The hook is rotatable between a lock position for gripping the striker that has entered the notch groove and an unlock position for releasing the striker, and the pole is engaged with the hook in the lock position so that the hook is locked. It is possible to rotate between an engagement position that prohibits rotation to the release position side and a non-engagement position that allows the hook to rotate to the lock release position side away from the hook. Further, a tension spring is provided between the hook and the pole, and the hook is always urged to rotate to the unlocking position side by the urging force (tensile force) of the tension spring, and the pole is always on the engagement position side. Rotation is energized.

In this type of lock mechanism, when the rotation range of the hook is mechanically restricted between the lock position and the unlock position, the hook or pole mounting position accuracy to the base member is low (the deviation from the design position is large). In this case, the pole rotated from the non-engagement position to the engagement position may not be engaged with the hook rotated from the unlock position to the lock position. For this reason, the base member restricts the hook from rotating beyond the unlocking position to the opposite side of the locking position, while the hook exceeds the locking position and rotates toward the overstroke position opposite to the unlocking position. In general, an allowable rotation range restricting means is provided.
However, when the hook can be rotated to the overstroke position in this way, when the passenger sits with the lock mechanism locking the striker, the hook located at the lock position rotates to the overstroke position side. Folding sheets will rattle. Further, even when the user is not seated, the hook may rotate to the overstroke position side due to vibrations when the vehicle travels, and the folding seat may rattle.

Therefore, the applicant of the present invention provides the lock mechanism with a rotation prevention member that rotates coaxially with the pole, and the engagement pin formed on the pole and the engagement pin formed on the rotation prevention member are fitted so as to be relatively movable. An invention has been completed in which a linkage means for linking the rotation of the pole and the rotation preventing member with the engagement hole is completed, and a patent application has already been filed (Patent Document 1).
In this invention, when the pole rotated to the engagement position and the hook rotated to the lock position are engaged, the rotation preventing member is engaged with the hook from the side opposite to the pole. Therefore, even if a seating load or the like is applied to the seat portion, the rotation preventing member can prevent the hook from rotating to the overstroke position side.
Further, the pole is linked to an operation lever provided on the folding sheet via a wire. Therefore, when the operation lever is operated in the locked state, the pole located at the engagement position rotates to the non-engagement position, and the engagement between the pole and the hook is released. Further, when the pole rotates to the non-engagement position, the engagement pin of the pole presses the peripheral edge portion of the engagement hole of the rotation prevention member, so that the rotation prevention member separates from the hook after the movement of the pole. By operating the operation lever in this manner, the locked state of the striker by the lock mechanism can be released.
JP 2005-329804 A

In Patent Document 1, since the operation lever and the pole are linked via a wire, the following problem may occur.
That is, in order to prevent the hook and pole from being unexpectedly released when the locking mechanism is in the locked state, the contact surface of the hook and the pole is shaped so that both are firmly engaged in the locked state. It has been processed. Moreover, when the lock mechanism is in the locked state, the rotation prevention member restricts the rotation of the hook toward the overstroke position. Therefore, if the mounting position of the hook or pole on the base member is slightly deviated from the design position, the sliding contact force (friction resistance) between the pole and the hook when operating the control lever in the locked state increases. The rotating operation toward the non-engagement position becomes unsmooth.

  The object of the present invention is to reliably prevent the hook from rotating unexpectedly toward the overstroke position even when an external force is applied to the lock mechanism in the locked state, and even when the mounting position accuracy between the pole and the hook is low. An object of the present invention is to provide a vehicular locking device capable of smoothly rotating a pole engaged with a hook in a direction to release the engagement with the hook.

  The vehicle locking device of the present invention is provided with a striker on one of a vehicle body and a rotating member that is rotatable with respect to the vehicle body or a detachable detachable member, and a lock mechanism that engages and disengages the striker on the other. And a hook that is rotatable between the unlocking position for releasing the striker and the locking position for gripping the striker and is urged to rotate toward the unlocking position. Rotation range restricting means that restricts rotation from the unlocked position in the opposite direction to the locked position while allowing rotation from the locked position to the overstroke position in the opposite direction to the unlocked position, and the locked position An engagement position that restricts the hook from rotating to the unlocking position side by engaging with a hook located at a position apart from the hook. A hook that is rotatable between a non-engagement position that allows the hook to rotate toward the unlocking position and that is urged to rotate toward the engagement position, and a hook that is located at the lock position. A rotation restriction position that restricts the hook from rotating to the overstroke position side, and a rotation allowance that releases the engagement with the hook and allows the hook to rotate to the overstroke position side. An anti-rotation member that is rotatable to a position and is urged to rotate toward the rotation restriction position, and the rotation prevention member is linked to the rotation prevention member and resists the urging force toward the rotation restriction position. The operating means that can be moved to the rotation permissible position, the pole and the rotation preventing member are linked, and the pole is located at the engagement position and engages with the hook located at the lock position. When the rotation preventing member is positioned at the rotation restricting position and the rotation preventing member rotates from the rotation restricting position to the rotation permissible position, the rotation preventing member is delayed to rotate to engage the pole. Linking means for rotating from a position to the disengaged position.

  The rotation preventing member and the pole can be rotated around a common rotation axis, and the linking means includes an engagement hole formed in one of the pole and the rotation preventing member, and a protrusion provided on the other. It is possible to provide an engagement pin that can be relatively moved in the direction of the arc around the common rotation axis and fits into the engagement hole.

  It is possible to fix the striker on a floor surface in a vehicle and provide the lock mechanism on a folding sheet that is the rotating member that is rotatable relative to the floor surface.

According to the present invention, when the pole positioned at the engaging position is engaged with the hook positioned at the locking position, the rotation preventing member positioned at the rotation restricting position is engaged with the hook. Therefore, even if a seating load or the like is applied to the lock mechanism in the locked state, it is possible to reliably prevent the hook from unexpectedly rotating to the overstroke position side.
Further, when the operating means is operated, the rotation preventing member located at the rotation restricting position rotates to the rotation allowable position and releases the engagement with the hook. Then, after the hook can be rotated to the overstroke position side in this way, the pole linked to the rotation preventing member is delayed by the rotation of the rotation preventing member to the rotation allowable position side by the function of the linkage means. It rotates to the non-engagement position side. For this reason, even if the mounting position accuracy of the pole and the hook is low, the pole positioned at the engaging position can be smoothly rotated to the non-engaging position.

  According to the invention of claim 2, the linking means can be realized with a simple structure.

  According to the invention of claim 3, if the striker is locked by the lock mechanism, it is possible to reliably prevent the folding seat from rattling against the vehicle floor even if a large seating load or traveling vibration is applied to the folding seat.

Hereinafter, the present invention will be described based on illustrated embodiments.
First, a vehicle folding seat to which the present invention is applied and its peripheral members will be described. In the following description, the left side of FIGS. 1 and 2 is defined as “front”, the right side is defined as “rear”, and the front / back direction of the paper surface is defined as “left / right direction”.
FIG.1 and FIG.2 has shown the folding surface 10 provided in the floor surface F in a motor vehicle, and the floor surface F so that rotation was possible.
A pair of left and right support brackets 11 are fixed to the floor surface F, and the left and right support brackets 11 rotatably support the vicinity of both left and right ends of the rotating shaft 12 extending in the left-right direction. Further, a pair of left and right mounting brackets 13 are fixed to the vicinity of both left and right ends of the rotating shaft 12. The left and right mounting brackets 13 are respectively fixed to the front end portions of the lower surface of the bowl-shaped lower rail 14 extending in the front-rear direction and having an upper surface opened. Further, the left and right lower rails 14 are respectively supported by slidable upper rails 15 that extend in the front-rear direction and open at the lower surface, and the upper surfaces of the left and right upper rails 15 are on the left and right sides of the lower surface of the seat portion 16. The part is fixed. And the lower end part of the backrest 17 is attached to the rear-end part of the seat part 16 so that rotation around the axis of the left-right direction is possible.
The folding sheet 10 having such a structure can be rotated in the front-rear direction with respect to the floor surface F around the rotation shaft 12.
At the rear of the support bracket 11 on the floor surface F, the lower ends of a pair of left and right strikers 18 having an inverted U shape in front view are fixed.

As shown in FIGS. 3 to 10, the left and right lower rails 14 include a pair of left and right side walls 19 a and a bottom wall 19 b connecting the lower ends of the left and right side walls 19 a. An opening 19b1 is formed in the vicinity of the rear end portion of the bottom wall 19b, and a notch groove 20 is formed in the vicinity of the rear ends of the left and right side walls 19a so as to face substantially in the vertical direction. A lock mechanism 30 shown in an enlarged manner in FIGS. 3 to 10 is provided inside the left and right lower rails 14.
Next, the lock mechanism 30 and its operating device will be described.
As shown in detail in FIGS. 3 to 10, both end portions of a rotating shaft 31 extending in the left-right direction are fixed to the inner surface of the left and right side walls 19 a of the lower rail 14, and a hook 32 can be rotated on the rotating shaft 31. It is attached. Further, both end portions of a rotation shaft 39 positioned in front of the rotation shaft 31 and extending in the left-right direction are fixed to the inner side surfaces of the left and right side walls 19a, and a rotation center hole 40a ( 11) and a rotation center hole 45a (see FIG. 11) of the rotation preventing member 45 are rotatably fitted.
The hook 32 includes an engagement groove 33 into which the striker 18 can enter and an engagement protrusion 34. The peripheral surface of the engaging protrusion 34 includes a pole contact surface 35 and a rotation prevention member contact surface 36 that are separated from each other, and a sliding contact surface 37 that is located between the pole contact surface 35 and the rotation prevention member contact surface 36. It is made up of. As shown in the figure, a stopper (rotation range restricting means) 21 is installed between the inner side surfaces of the left and right side walls 19a, so that the hook 32 is counterclockwise ("clockwise" or "counterclockwise" in this description). (The direction when viewed in the direction of FIGS. 3 to 10) is restricted at the unlocking position (position of FIG. 3) where the peripheral surface (rear surface) of the hook 32 contacts the stopper 21. The hook 32 reaches the lock position shown in FIG. 7 by rotating clockwise from the unlock position. Then, when the striker 18 is engaged with the engagement groove 33, the hook 32 rotates to the lock position, so that the hook 32 locks the striker 18. Since the stopper 21 does not restrict the clockwise rotation of the hook 32, the hook 32 can be rotated further to the overstroke position on the clockwise side than the locked position.

The pole 40 is a plate-like member that is located on the same plane as the hook 32 (the positions in the left and right direction are the same). The pole 40 has a non-engagement position where it does not engage with the hook 32 (the position shown in FIG. 10), and a hook 32 where the locking surface 42, which is the peripheral surface of the locking projection 41 formed at the tip, is positioned at the locking position. It can rotate between the engagement positions (positions in FIG. 7) that contact the contact surface 35. Further, an engaging pin 43 projects from the surface of the pole 40 facing the rotation preventing member 45.
The anti-rotation member 45 is a plate-like member that is longer than the pole 40, and when viewed from the front, the distal end side is bent with respect to the proximal end side (see FIG. 11). The portion from the base end portion to the middle portion of the rotation preventing member 45 overlaps the pole 40 in the left-right direction, and the distal end portion 46 of the rotation preventing member 45 is located on the same plane as the pole 40 and the hook 32 (pole 40 and the rotation preventing member 45 are located at the same left-right position). An engagement hole 47 is formed in the rotation preventing member 45, and the engagement pin 43 of the pole 40 is fitted into the engagement hole 47 so as to be relatively movable in the arc direction around the rotation shaft 39. (The engaging pin 43 and the engaging hole 47 are components of the linking means). Further, an engagement protrusion 48 is formed at the tip 46 of the rotation prevention member 45, and a part of the peripheral surface of the engagement protrusion 48 can be engaged with and disengaged from the rotation prevention member contact surface 36 of the hook 32. A locking surface 49 is provided. The rotation preventing member 45 includes a rotation restricting position (position shown in FIGS. 3 and 7) where the locking surface 49 comes into contact with the rotation preventing member abutting surface 36 of the hook 32 and a rotation allowable position (position shown in FIG. 10) away from the hook 32. ).

Further, a winding portion of a torsion coil spring S1 located on the opposite side of the rotation preventing member 45 with the pole 40 interposed therebetween is wound around the rotation shaft 39. One locking end S1a of the torsion coil spring S1 is locked to the side surface of the pole 40 opposite to the hook 32, and the other locking end S1b is a through hole (not shown) drilled in the pole 40. It is locked to the side surface of the rotation preventing member 45 on the hook 32 side. This torsion coil spring S1 always urges the pole 40 to rotate clockwise (engagement position side), and always urges the rotation prevention member 45 to rotate counterclockwise.
Furthermore, both ends of the tension spring S2 are locked to the locking portion 38 protruding from the hook 32 and the locking portion 50 protruding from the rotation preventing member 45. The tension spring S2 always urges the hook 32 to rotate toward the unlock position (counterclockwise), and urges the rotation prevention member 45 to rotate toward the rotation restriction position (clockwise). Since the biasing force (tensile force) of the tension spring S2 is stronger than that of the torsion coil spring S1, the anti-rotation member 45 is always clockwise (although the counterclockwise biasing force by the torsion coil spring S1 is applied to the rotation prevention member 45). Try to rotate to the rotation restriction position side.
One end of a pair of left and right operation wires W is fixed to the engaging portion 51 projecting from the distal end portion 46 of the rotation preventing member 45 of the left and right lock mechanism 30, and the other end of the left and right operation wires W is left and right. It is fixed to an operation lever (operation means) 22 that is rotatably provided at the front end of one of the upper rails 15. The operation lever 22 is rotatable between a non-operation position (the position shown in FIGS. 1 and 2) and an operation position (not shown), and is always (when not operated) by a biasing means such as a spring (not shown). ) Is held in the non-operating position. When the operation lever 22 is positioned at the non-operation position, the rotation preventing member 45 is positioned at the rotation restricting position by the urging force of the tension spring S2 (see FIGS. 3 and 7). On the other hand, when the operation lever 22 is located at the operation position, the rotation preventing member 45 is located at the rotation allowable position against the urging force of the tension spring S2 (see FIG. 10).

Next, the operation of the lock mechanism 30 configured as above will be described.
When the folding sheet 10 is located at the folding position shown in FIG. 2 (the position where the seat 16 and the backrest 17 are substantially vertical), the striker 18 has escaped from the notch groove 20 and the lock mechanism 30 of the lower rail 14 and is locked. The mechanism 30 is in the unlocked state shown in FIG. At this time, the hook 32 is located at the unlocking position. Further, since the operating lever 22 is located at the non-operating position, the rear surface of the pole 40 that is urged counterclockwise by the torsion coil spring S1 contacts the sliding contact surface 37 of the hook 32 at the unlocking position. Touching. On the other hand, the rotation preventing member 45 is located at the rotation restricting position because the operation lever 22 is located at the non-operation position, and the front portion of the engagement pin 43 contacts the front portion of the engagement hole 47.
When the folding sheet 10 is rotated backward about the rotation shaft 12 and rotated to the use position shown in FIG. 1 while the operation lever 22 is positioned at the non-operation position, the striker 18 enters the notch groove 20, and Since the striker 18 engages with the engagement groove 33 of the hook 32, the hook 32 rotates clockwise (lock position side) against the urging force of the tension spring S2 (see FIG. 4). Then, the hook 32 rotates with its sliding contact surface 37 slidingly contacting the locking projection 41 of the pole 40, so that the pole 40 rotates counterclockwise against the biasing force of the torsion coil spring S1. Further, since the engaging pin 43 of the pole 40 presses the front portion of the engaging hole 47 of the rotation preventing member 45 forward, the rotation preventing member 45 is slightly rotated counterclockwise from the rotation restricting position in FIG. When the corner between the pole contact surface 35 and the sliding contact surface 37 of the hook 32 gets over the locking protrusion 41 of the pole 40, the pole 40 is moved by the biasing force of the torsion coil spring S1, as shown in FIG. Rotating clockwise, the locking surface 42 of the pole 40 and the pole contact surface 35 of the hook 32 are engaged. Further, due to the biasing force of the tension spring S <b> 2, the rotation preventing member 45 is slightly rotated in the clockwise direction while maintaining the contact state between the engagement hole 47 and the engagement pin 43. Then, as shown in FIG. 5, the engaging protrusion 48 of the rotation preventing member 45 is positioned immediately above the rotation preventing member abutting surface 36 of the hook 32 (the rotation preventing member abutting surface 36 of the hook 32 and the rotation preventing member 45. The locking surface 49 is non-contact).

Even after the locking surface 42 of the pole 40 is engaged with the pole contact surface 35 of the hook 32, the biasing force of the torsion coil spring S1 reaches the pole 40 and the rotation preventing member 45, and the biasing force of the tension spring S2 prevents rotation. It extends to the member 45. Therefore, as shown in FIG. 6, the pole 40 further rotates in the clockwise direction, the rotation preventing member 45 returns to the rotation restricting position, and the locking surface 49 of the rotation preventing member 45 is the rotation preventing member contact surface of the hook 32. 36 abuts.
Even after the rotation preventing member 45 rotates to the rotation restricting position, the urging force of the torsion coil spring S1 reaches the pole 40, and the urging force of the torsion coil spring S1 causes the pole 40 to further rotate clockwise from the position of FIG. To do. As a result, the pole 40 rotates to the engagement position shown in FIG. 7 while separating the engagement pin 43 from the front portion of the engagement hole 47, and the locking protrusion 41 of the pole 40 is connected to the pole contact surface 35 of the hook 32. It comes into contact with the stopper surface 32a which is a peripheral surface (front surface).
Thus, when the lock mechanism 30 is locked by the hook 32 rotating to the locked position while gripping the striker 18 and the pole 40 rotating to the engaged position, the torsion coil spring S1 and the tension spring S2 are rotated. Since the engaging surface 42 of the pole 40 and the pole contact surface 35 of the hook 32 are firmly engaged by the force, the pole 40 restricts the rotation of the hook 32 toward the unlocked position (counterclockwise rotation). . Further, the engagement protrusion 48 of the rotation preventing member 45 restricts the clockwise rotation of the hook 32.
If the folding seat 10 is locked to the floor F in this way and then the backrest 17 is raised until it becomes substantially vertical as shown in FIG. 1, the folding seat 10 is in a state in which a passenger can be seated. Then, since the pole 40 and the rotation preventing member 45 regulate the rotation of the hook 32 toward the unlock position and the rotation from the lock position to the overstroke position on the clockwise side, a large downward load ( For example, even when a seating load is applied, the hook 32 does not rotate from the lock position to the overstroke position side, so that the folding sheet 10 does not rattle against the floor surface F.

In order to rotate the folding sheet 10 thus locked in the use position to the folding position shown in FIG. 2, first, the backrest 17 is tilted forward until it becomes parallel to the seat portion 16, and the operation lever 22 is moved to the operation position side. Move. Then, as shown in FIG. 8, the anti-rotation member 45 located at the rotation restricting position rotates counterclockwise, so that the locking surface 49 of the anti-rotation member 45 is separated from the anti-rotation member contact surface 36 of the hook 32. Separate.
When the operation lever 22 further approaches the operation position, the rear portion of the engagement hole 47 of the rotation preventing member 45 contacts the rear portion of the engagement pin 43 as shown in FIG. Rotates counterclockwise (non-engagement position) while slightly rotating the hook 32 clockwise (overstroke position).
When the operation lever 22 is moved to the operation position, the rotation preventing member 45 reaches the rotation allowable position and the pole 40 reaches the non-engagement position as shown in FIG. Canceled. Therefore, if the folding sheet 10 is rotated forward about the rotation shaft 12 in this state, the hook 32 is rotated to the unlocked position by the rotation biasing force of the tension spring S2, and the striker 18 is engaged with the notch groove 20 and the engagement. Since it escapes from the joint groove 33, the folding sheet | seat 10 can be rotated to a folding position.
Thereafter, when the operation lever 22 is returned to the non-operation position, the lock mechanism 30 returns to the unlocked state shown in FIG.

  As described above, according to the present embodiment, by providing the stopper 21, the hook 32 is restricted from rotating counterclockwise from the unlocked position, but the hook 32 is rotated clockwise from the locked position. Therefore, even if the mounting position of the hook 32 and the pole 40 with respect to the lower rail 14 (side wall 19a) is slightly deviated from the design position (even if the mounting position accuracy is low), the hook 32 and the pole 40 are securely engaged and disengaged. It is possible. Further, since the pole 40 and the rotation preventing member 45 sandwich the hook 32 positioned at the lock position when the lock mechanism 30 is in the locked state, it is possible to reliably prevent the folding sheet 10 from rattling unexpectedly due to a load at the time of sitting.

  Moreover, when the striker 18 is unlocked by the lock mechanism 30, the rotation preventing member 45 located at the rotation restricting position is rotated in advance to the rotation allowable position side so that the hook 32 can be rotated to the overstroke position side. After that, the pole 40 located at the engagement position is rotated to the non-engagement position side. Therefore, as in the case where the pole 40 is rotated to the non-engagement position while the rotation prevention member 45 restricts the rotation of the hook 32 to the overstroke position, the sliding of the locking surface 42 and the pole contact surface 35 is performed. Since the contact force (friction resistance) does not increase, the engagement release operation between the pole 40 and the hook 32 can be performed smoothly.

Although the present invention has been described based on the above embodiment, the present invention is not limited to the above embodiment and can be implemented in various modes.
For example, the lock mechanism 30 is provided on a vehicle door (not shown) as a rotating member, and when the vehicle door is fully closed, the striker protruding from the vehicle body is locked by the lock mechanism 30 to keep the vehicle door fully closed. You may make it do.
Further, the lock mechanism 30 is provided at the bottom of a seat (detachable member, not shown) that can be attached to and detached from the floor surface F, and the lock mechanism 30 protrudes from the floor surface F when the seat is attached to the floor surface. You may lock your striker.
Furthermore, a locker 30 may be provided on the vehicle main body side by projecting a striker on the rotating member side or the detachable member side.
In addition, an engaging pin may be provided on the anti-rotation member 45 side, and an engaging hole may be provided on the pole 40 side to constitute a link means for the pole 40 and the anti-rotation member 45.
Further, the torsion coil spring S1 and the tension spring S2 may be implemented in place of urging means having another structure having the same function as these.
