It is fixed. And the outer surface reinforcement board 11F is addressed from the inner surface to the end wall opposite to the center of rotation of the door (not shown) of the rear seat of the vehicle, for example, and is fixed with bolts.

  Further, a striker receiving groove 12 extending in the horizontal direction is formed on the first outer surface 11A of the support body 11 so as to overlap the first cover 11E and the outer surface reinforcing board 11F. A striker receiving port 12K at one end of the striker receiving groove 12 opens in the second outer surface 11B opposite to the first outer surface 11A across the bent portion of the support body 11. Then, the striker receiving groove 12 is exposed to the outside of the door through the notch hole formed in the door, and the striker 15 (see FIG. 3) provided on the inner surface of the door frame of the vehicle body closes the striker. The striker receiving groove 12 enters from the receiving port 12K.

  The striker 15 as a whole has, for example, a gate structure in which a wire having a circular cross section is bent, and a pair of leg portions of the gate structure protrude from the inner surface of the door frame and are arranged in the inner and outer directions. Then, a latch 13 described below engages with one of the pair of legs of the striker 15 arranged on the outer side. 3 and 4 show only a portion of the striker 15 that engages with the latch 13.

  The latch 13 and the ratchet 14 (sometimes referred to as “pole”) shown in FIGS. 3 and 4 are assembled to a portion of the first cover 11E covered with the outer reinforcing plate 11F. 14 constitutes a latch mechanism 10R according to the present invention. As shown in FIG. 3, the latch 13 has first and second locking claws 13A and 13B which are parallel to each other, and a striker is received between the first and second locking claws 13A and 13B. Part 13C. A latch support shaft 13J passes through a portion of the latch 13 that connects the first and second locking claws 13A, 13B, and the latch 13 is centered on the latch support shaft 13J. It rotates in a plane parallel to the first outer surface 11A. The latch support shaft 13J passes through the base wall 11C of the first cover 11E facing the outer surface reinforcing plate 11F, and one end thereof is fixed to the outer surface reinforcing plate 11F.

  The latch 13 is biased in the unlatching direction (clockwise direction in FIG. 3) by a torsion spring (not shown) provided between the latch 13 and the support body 11. When the door is opened, the latch 13 is positioned at the unlatched position (position shown in FIG. 3) by the contact between the stopper contact portion 13D provided on the latch 13 and the stopper 11X provided on the support body 11. .

  In the unlatched position, the first locking claw 13A is retracted above the striker receiving groove 12 and the second locking claw 13B crosses the striker receiving groove 12, and the open end of the striker receiving portion 13C is the striker. It faces the striker receiving port 12K side of the receiving groove 12.

On the other hand, as shown in FIGS. 10 and 15, the pressure receiving contact portion 52 </ b> A is located on the rotation locus of the pressing piece 21 in the inside open lever 20 when the chipro lever 50 is disposed at the unlock position. 11 and FIG. 16, when the chipro lever 50 is disposed at the lock position, it shifts from the rotation locus of the pressing piece 21 in the inside open lever 20 to the long hole 11H side, The contact avoidance hole 53 is located on the rotation locus of the pressing piece 21 in the inside open lever 20. That is, when the chipro lever 50 is disposed at the unlocked position, the pressure receiving contact portion 52A that contacts the pressing piece 21 of the inside open lever 20 and the pressure contact that contacts the pressure receiving piece 17C of the outside open lever 17 The abutting portion 52 </ b> B is disposed on the rotation locus of the pressing piece 21 in the inside open lever 20.

  This completes the description of the configuration of the door lock device 10 of the present embodiment. Next, the effect of the door lock device 10 will be described. For example, the door lock device 10 is attached to a door (not shown) of a rear seat of the vehicle. In general, the chipro lever 50 is disposed at the unlock position. For example, when an infant rides on the rear seat, the chipro lever 50 is disposed at the lock position.

  The door lock is released by the operation of a lock operation unit, a cylinder key or the like provided in the vehicle, and the chipro lever 50 is placed in the state shown in FIG. 15 in a state where the open link 19 is disposed at the unlock position as shown in FIG. In the case where it is arranged at the unlocked position, the inside open lever 20 is rotated from the origin position to the operating position by operating the inside door handle. Then, in the middle, the pressing piece 21 of the inside open lever 20 contacts the pressure receiving contact portion 52A and the chipro lever 50 is pushed upward to rotate from the origin position to the operating position, and the chipro lever 50 is pressed. The outside open lever 17 is pushed by the contact portion 52B and rotates from the origin position to the operating position as shown in FIGS. 5 (B) to 6 (B). At this time, as shown in FIG. 7, the contact portion T1 between the pressing piece 21 of the inside open lever 20 and the sandwiched block 52 and the contact portion T2 between the sandwiching block 52 and the pressure receiving piece 17C of the outside open lever 17 are obtained. Is shifted from each other in the plate thickness direction of the chipro lever 50 (the left-right direction in FIG. 7). Then, when the outside open lever 17 rotates with the rotation of the inside open lever 20, the contact portion T2 approaches the contact portion T1 so as to line up in the vertical direction.

  When the push-up protrusion 19C pushes up the tip contact portion 16B of the lift lever 16 by the rotation of the outside open lever 17 to the operating position, the lift lever 16 is released from the origin position together with the ratchet 14 (see FIG. 4). Rotating to the position, the ratchet 14 and latch 13 are disengaged and the door is opened. That is, the inside open lever 20, the chipro lever 50, the outside open lever 17, the open link 19 and the lift lever 16 corresponding to the “force transmission component” of the present invention are the latch release operation force by the operation of the inside door handle. It is transmitted and applied to the latch mechanism 10R, and the latch of the door by the latch mechanism 10R is released.

  In order to move the chipro lever 50 from the unlock position to the lock position, the operation shaft 61 (see FIG. 1) exposed on the end face of the door may be operated. When the chipro lever 50 is moved from the unlocked position to the locked position by operating the operation shaft 61, the pressure receiving contact portion 52A of the chipro lever 50 is moved to the inside open lever 20 as shown in the change in FIGS. The contact avoidance hole 53 is located on the rotation locus of the pressing piece 21 in the inside open lever 20 by deviating from the rotation locus of the pressing piece 21 toward the long hole 11H. When the inside open lever 20 is rotated from the origin position to the operating position by the operation of the inside door handle, the pressing piece 21 enters the contact avoidance hole 53. As a result, when the chipro lever 50 is disposed at the lock position, the latch release operation force due to the operation of the inside door handle is interrupted by the chipro lever 50, and the latch release operation force is not transmitted to the latch mechanism 10R, and the latch The door latch by the mechanism 10R is held. That is, even if the door lock is released, the latch cannot be released by operating the inside door handle, and a situation where a child in the rear seat accidentally opens the door can be prevented. That is, the child protection function is enabled.

  Here, if the contact avoidance hole 53 is not formed in the chipro lever 50, the pressing piece 21 of the inside open lever 20 is moved to the chipro lever 50 only by slightly shifting the chipro lever 50 to the lock position side. It becomes impossible to block the latch release operation force with the chipro lever 50 by contacting the portion adjacent to the pressure receiving contact portion 52A. On the other hand, in the door lock device 10 of the present embodiment, since the contact avoidance hole 53 is formed between the pressure receiving contact portion 52A and the pressing contact portion 52B of the chipro lever 50, the chipro lever The pressing piece 21 of the inside open lever 20 enters the contact avoidance hole 53 of the chipro lever 50 and the latch release operation force is interrupted by the chipro lever 50 by only slightly shifting 50 to the lock position side. Can do. That is, in the door lock device 10 according to the present embodiment, the movement space of the chipro lever 50 that is operated to move between the locked position and the unlock position can be made smaller than that of the prior art. While the freedom degree of arrangement | positioning becomes high, the door lock apparatus 10 whole can be made compact.

  Further, in the door lock device 10 of the present embodiment, the chipro lever 50 has a structure including the sandwiched block 52 on one side surface of the belt-like lever body 50H extending from the rotation shaft. The clamp body 52 can be disposed between the inside open lever 20 and the outside open lever 17 by extending the lever main body 50H of the chipro lever 50 so as to sew a gap between the parts constituting the locking device 10. . Furthermore, since the inside open lever 20 has a shape in which a protruding piece-like pressing piece 21 is bent at a right angle from the outer edge on the front end side of the plate-like lever body 20H, the inside open lever 20 can be manufactured with sheet metal at a low cost. it can.

  When the door is locked by an operation of a lock operation unit, a cylinder key or the like provided in the vehicle and the open link 19 is disposed at the lock position as shown in FIG. 5A, the inside door handle and the outside door Even if the outside open lever 17 is rotated from the origin position to the operating position by any operation of the handle, the push-up protrusion 19C does not push up the tip contact portion 16B of the lift lever 16 (see FIG. 6A). ), The latch of the door by the latch mechanism 10R is held.

[Second Embodiment]
The door lock device of this embodiment is demonstrated based on FIGS. This embodiment is different from the first embodiment in that a malfunction control protrusion 50T is provided on the chipro lever 50V. Specifically, as shown in FIG. 24A, the malfunction restricting protrusion 50T has a prismatic shape with a deformed cross section that protrudes in the same direction as the connecting protrusion 51 from a position near the tip of the lever body 50H. Further, as shown in FIG. 23, the protruding amount of the malfunction restricting protrusion 50T is about half of the protruding amount of the connecting protrusion 51. And the groove side wall 64F of the rotation protrusion 64 in the switching lever 60 on the rotation shaft part 54 side from the engagement groove 62 is sandwiched between the connection protrusion 51 and the malfunction restricting protrusion 50T. A gap 64P is formed between the outer surface of the groove side wall 64F and the malfunction restricting protrusion 50T.

  Further, the lower end portion of the outer side surface of the groove side wall 64F is a lower inclined surface 64U inclined downward from the malfunction restricting protrusion 50T. Further, the upper portion of the outer side surface of the groove side wall 64F above the lower inclined surface 64U is a protrusion adjacent surface 64V that is rounded so that the center in the vertical direction is slightly separated from the malfunction restricting protrusion 50T. As shown in FIGS. 25 (A) and 25 (B), when the chipro lever 50V is disposed at the locked position, the malfunction restricting projection 50T faces the lower slope 64U of the groove side wall 64F, and As shown in FIG. 24A, when the chipro lever 50V is disposed at the unlocked position, the malfunction restricting projection 50T is formed into the projection adjacent surface 64V in the groove side wall 64F. Opposing the boundary portion between the lower slope 64U and the gap 64P described above becomes relatively small. Furthermore, when the inside door handle is operated and the chipro lever 50V is lifted by the inside open lever 20 in a state where the chipro lever 50V is disposed at the unlock position, a malfunction occurs as shown in FIG. The restriction protrusion 50T faces the position near the upper end of the protrusion adjacent surface 64V of the groove side wall 64F, and the gap 64P is further reduced. At this time, one side surface of the malfunction restricting protrusion 50T is substantially parallel to the groove side wall 64F.

  This completes the description of the configuration of the door lock device of the present embodiment. In the door lock device according to the present embodiment, when the switching lever 60 is erroneously operated as follows, the switching lever 60 can be prevented from malfunctioning and the operator can be made aware of the erroneous operation. That is, normally, the operation of the switching lever 60 should be performed with the hand released from the inside door handle. For example, the state in which the inside door handle is opened with one hand and the other hand is used. It is conceivable to perform an erroneous operation of moving the switching lever 60 from the unlock position to the lock position. When such an erroneous operation is performed, as shown in FIG. 24 (B), the pressing piece 21 of the inside open lever 20 comes into contact with the surface of the sandwiched block 52 on the rotating shaft portion 54 side. In a state where 50V is restricted from moving from the unlock position to the lock position, the switching lever 60 is rotated from the unlock position to the lock position.

  If the above-mentioned erroneous operation is performed, the rotational resistance of the switching lever 60 increases. However, if the malfunction restricting projection 50T is not provided, the switching lever 60 may be erroneously operated regardless of the increase of the rotational resistance. Subsequently, the rotating protrusion 64 of the switching lever 60 is deformed so that the engaging groove 62 is expanded. Then, while the chipro lever 50V is in the unlocked position, the switching lever 60 malfunctions and rotates to the locked position. For this reason, the operator can determine that the child protection function has been activated by noticing the erroneous operation and turning the switching lever 60 to the lock position. However, if the hand is released from the inside door handle, the inside open lever 20 returns to the origin position, and the door opens when the inside door handle is opened again by closing the door. That is, contrary to the operator's will, a situation may occur in which the child protection function is not enabled.

  On the other hand, the chipro lever 50V of the present embodiment is provided with the malfunction restricting protrusion 50T, so that the switching lever 60 is erroneously operated as described above, and the rotating protrusion 64 of the switching lever 60 is slightly changed. When deformed, the groove side wall 64F of the rotating protrusion 64 comes into contact with the malfunction restricting protrusion 50T. As a result, the rotating protrusion 64 can no longer be operated in the locking direction, and the switching lever 60 is fixed at the unlock position. That is, according to the configuration of the present embodiment, it is possible to prevent an erroneous operation due to an erroneous operation of the switching lever 60, thereby making it possible for the operator to notice that an erroneous operation has been performed. Then, the operator who has noticed the erroneous operation can release the hand from the inside door handle by trial and error and rotate the switching lever 60 to the lock position to enable the child protection function normally. In a normal state, the malfunction regulating protrusion 50T and the rotating protrusion 64 do not interfere with each other due to the gap 64P between the malfunction restricting protrusion 50T and the rotating protrusion 64.

[Third Embodiment]
The door lock device of the present embodiment is shown in FIG. 26. In the second embodiment, erroneous operation of the switching lever 60 is prevented by the malfunction restriction protrusion 50T provided on the chipro lever 50V. The present embodiment is different in that a reinforcing protrusion 60T is provided on the switching lever 60W to prevent erroneous operation of the switching lever 60W.

  Specifically, as shown in FIG. 26B, the reinforcing protrusion 60T has a rectangular parallelepiped shape, and an opening edge between the reinforcing protrusion wall 60C and the engaging groove 62 described in the first embodiment. It is arranged between. Then, as shown in FIG. 26A, in the state where the chipro lever 50 is disposed at the unlock position and the inside open lever 20 is moved to the operating position and lifts the chipro lever 50, the reinforcing protrusion 60T is It is located in the vicinity of the connecting protrusion 51. Thereby, even if the switching lever 60W is erroneously operated, the rotating protrusion 64 is reinforced by the reinforcing protrusion 60T and is not greatly deformed, and the switching lever 60W is fixed at the unlock position. In other words, even with the configuration of the present embodiment, it is possible to prevent an erroneous operation due to an erroneous operation of the switching lever 60W, thereby making it possible for the operator to notice that an erroneous operation has been performed.

[Fourth Embodiment]
This embodiment is shown in FIG. 27 and is different from the third embodiment in that a corrugated surface 52M is formed on the pressure receiving contact portion 52A in the clamped block 52 of the chipro lever 50X. The corrugated surface 52M is formed by alternately arranging peaks 52X and valleys 52Y having ridge lines parallel to the rotation axis of the chipro lever 50X (that is, the central axis of the rotation shaft portion 54). When viewed from the rotational axis direction, for example, the crest 52X and the trough 52Y are continuous in an arc shape that is mutually inverted. In addition, grease (not shown) is accumulated in the valley 52Y of the corrugated surface 52M. When the inside open lever 20 is rotated from the origin position to the operating position in a state where the chipro lever 50X is disposed at the unlock position, the pressing piece 21 of the inside open lever 20 comes into sliding contact with the corrugated surface 52M. At this time, if a granular foreign material (for example, sand particles) adheres on the pressing piece 21, the foreign material is received by the valley portion 52Y of the corrugated surface 52M. Thereby, generation | occurrence | production of the noise by the biting of a foreign material can be prevented, and the fluctuation | variation of the rotation resistance of the inside open lever 20 can be suppressed, and the operational feeling of an inside door handle is stabilized.

[Other Embodiments]
The present invention is not limited to the above-described embodiment. For example, the embodiments described below are also included in the technical scope of the present invention, and various other than the following can be made without departing from the scope of the invention. It can be changed and implemented.

(1) In the above-described embodiment, the contact avoidance hole 53 penetrates the sandwiched block 52. However, if the contact avoidance hole 53 can receive the pressing piece 21 (the rush pressing portion), the sandwiched block is prevented. 52 may not be penetrated.

(2) In the above embodiment, the latch release operation by the inside door handle is switched between enabled and disabled by switching between the locked position and the unlocked position of the chipro lever 50, but the inside door handle and the outside door handle The present invention may be applied by forming a contact avoidance hole 53 in a part for switching between both of the latch release operations between valid and invalid.

(3) In the corrugated surface 52M of the fourth embodiment, the ridge line of the crest 52X of the corrugated surface 52M is oriented in a direction parallel to the rotation axis of the chipro lever 50X. For example, FIG. As shown in FIG. 28C, the ridgeline of the crest 52X of the corrugated surface 52M may be formed so as to face the direction perpendicular to the rotation axis of the chipro lever 50Y.

(4) Instead of providing the corrugated surface 52M on the clamped block 52 of the chipro lever 50, the corrugated surface 52M described above may be provided on the pressing piece 21 of the inside open lever 20. Furthermore, instead of the corrugated surface 52M, a single foreign substance removing groove may be provided in the pressing piece 21 of the inside open lever 20 or the sandwiched block 52 of the chipro lever 50. Further, a plurality of protrusions and a plurality of through holes may be provided in the sandwiched block 52 or the pressing piece 21 instead of the corrugated surface 52M.

(5) The pivot shaft portion 54 of the chipro lever 50 of the first embodiment has a so-called snap-fit structure in which the rotation shaft portion 54 is retained by the elongated hole 11H through elastic deformation. For example, FIG. Like the rotation shaft portion 54V of the chipro lever 50Z shown in the figure, a pair of locking projections 54H and 54H are provided on the side surface of the cylindrical portion 54E protruding from the base end portion of the lever body 50H. Also good. According to this structure, the chipro lever 50Z is inserted into the elongated hole 11H of the second cover 11G in a substantially vertical posture in which the pair of locking protrusions 54H and 54H are horizontally aligned, and then the chipro lever 50Z is inserted. By changing 50Z to a substantially horizontal posture, as shown in FIG. 30, the pair of locking protrusions 54H and 54H are locked to the opening edge of the long hole 11H on the outer surface of the second cover 11G, and rotated. The shaft portion 54V can be retained in the long hole 11H.

  In the chipro lever 50Z shown in FIG. 29, the pair of locking projections 54H and 54H are arranged in a semicircle unevenly on the side away from the coupling projection 51 of the cylindrical portion 54E, while the lever The base end portion of the main body 50H is arranged up to a semicircle on the coupling protrusion 51 side in the cylindrical portion 54E. With this configuration, when the locking protrusions 54H and 54H are passed through the long hole 11H, the rotation shaft portion 54V side of the chipro lever 50Z in a substantially vertical posture is brought close to the second cover 11G, and the opposite side thereof. Is tilted away from the second cover 11G. Thereby, it becomes difficult for the rotation shaft portion 54V to fall out of the long hole 11H.
