  By the way, in order to improve the production efficiency of the door lock device, it is desired to reduce the number of parts of the door lock device. However, conventionally, the door lock device has not been improved from such a viewpoint.

  This invention is made | formed in view of such a situation, The objective is to provide the sliding door guide apparatus provided with the door lock apparatus with few parts count, and the door lock apparatus.

  (1) A door lock device that solves the above problems includes a latch that engages with a striker attached to a vehicle, a lock member that engages with the latch and stops rotation of the latch, and the latch and the lock member A support member that rotatably supports the latch, and an engagement position that biases the latch so that the latch moves toward an engageable position where the latch can engage with the striker and the lock member engages with the latch. And an urging member that urges the lock member to face.

  According to this configuration, the latch and the lock member are urged by the single urging member. For this reason, compared with the conventional structure in which the urging member is provided for each of the latch and the lock member, the number of parts is small.

  (2) In the door lock device, the biasing member is a spring member having a first coil portion and a second coil portion, and the first coil portion is inserted through a support shaft of the latch, The two coil portions are inserted into the support shaft of the lock member, and the end on the first coil portion side is hooked on the latch so that the latch is biased toward the engageable position, and the lock The end portion on the second coil portion side is hooked on the lock member so that the member is biased toward the engagement position.

  According to this configuration, since the first coil portion of the urging member is inserted through the support shaft of the latch and the second coil portion is inserted through the support shaft of the lock member, the first coil portion is inserted by another support shaft. The number of support shafts is reduced as compared to the structure to be supported or the structure in which the second coil portion is supported by another support shaft. Thereby, compared with these comparative structures, a door lock device becomes small.

  (3) In the door lock device, when the door lock device is disposed on a slide door of the vehicle via a bracket, the latch is disposed above the first coil portion, and the second coil The lock member is disposed above the portion.

  The door lock device is attached to a vehicle door via a bracket. According to the configuration as described above in the arrangement of the door lock device when attached to the door of the vehicle, the latch is arranged below the first coil part and the lock member is arranged below the second coil part. Compared to the structure, the latch and the lock member are arranged on the upper side of the bracket compared to the structure. If it does so, it will become possible to shorten the length of the striker engaged with a latch in the up-and-down direction, and this makes it possible to make the striker approach the bent corner on the rear side of the entrance / exit. Thereby, the opening area of the entrance / exit of a sliding door can be expanded. That is, the door lock device having the above-described configuration makes it possible to dispose the striker further rearward, thereby enabling the opening area of the entrance / exit of the slide door to be enlarged.

  (4) In the door lock device, the biasing member is inserted into the support member so that the first coil portion is inserted into the support shaft of the latch and the second coil portion is inserted into the support shaft of the lock member. The lock member is disposed on the second coil portion so that a space for the latch is disposed is disposed, and the latch is disposed in the space. When the first coil portion is hidden, the end portion on the first coil portion side protrudes from the latch.

  According to this configuration, even when the first coil portion is hidden by arranging the latch in the space, the end portion on the first coil portion side protrudes from the latch. That is, since the end portion on the first coil portion side is not hidden behind the latch, the operation of hooking the end portion on the first coil portion side on the latch is simplified in the assembly of the door lock device.

  (5) The slide door guide device includes a roller unit that slides on a guide rail of the vehicle, and the door lock device. Since the slide door guide device having this configuration includes the door lock device, the number of parts is small.

  The door lock device and the slide door guide device have fewer parts than conventional door lock devices.

The striker 4 is attached near the rear edge and near the lower edge of the entrance / exit 1a.

  As shown in FIGS. 2 and 3, the bracket 11 includes a fixing portion 12 that is fixed to the slide door 2 and an extension portion 13 that extends from the lower portion of the fixing portion 12 toward the vehicle 1. The bracket 11 is formed of a steel material, and a fixed portion 12 and an extension portion 13 are formed by pressing. The extension portion 13 extends toward the vehicle 1 as it goes forward. A roller unit 15 that slides on the guide rail 3 and a door lock device 20 are provided at the distal end portion 14 of the bracket 11 (that is, the distal end portion 14 of the extension portion 13). The door lock device 20 is disposed behind the roller unit 15.

The door lock device 20 will be described with reference to FIG.
The door lock device 20 includes a latch 30 that engages with the striker 4, a lock member 40 that engages with the latch 30 and stops the rotation of the latch 30, and a support member 50 that rotatably supports the latch 30 and the lock member 40. And an urging member 60.

The support member 50 rotatably supports the latch 30 and the lock member 40.
The support member 50 includes a base plate 51 and wall portions 52 provided on the edge of the base plate 51. A cable fixing portion 53 for fixing a cable 70 for rotating the lock member 40 is provided on the vehicle width outer side of the base plate 51. The distal end portion of the inner cable 71 of the cable 70 is connected to the lock member 40.

  The base plate 51 includes a first support shaft 54 (a support shaft for the latch) that rotatably supports the latch 30 and a second support shaft 55 (a support shaft for the lock member) that rotatably supports the lock member 40. It is attached. The first support shaft 54 is disposed in front of the second support shaft 55. The first support shaft 54 is provided in the vicinity of the edge of the base plate 51 so that the engagement recess 32 (see later) of the latch 30 can be disposed outside the base plate 51.

The latch 30 includes a bearing portion 31 supported by the first support shaft 54, an engagement concave portion 32 through which the striker 4 is inserted, and an engagement portion 33 into which the lock member 40 is engaged.
The engaging recess 32 is provided between two arms extending from the bearing portion 31 (hereinafter, the front arm is referred to as “first arm 34” and the rear arm is referred to as “second arm 35”).

  The engaging portion 33 is disposed on the opposite side of the engaging recess 32 with the bearing portion 31 interposed therebetween. The engaging part 33 is configured in a sector shape. A contact surface 36 with which the hook surface 43 a of the hook portion 43 of the lock member 40 abuts is provided on the latch portion biasing direction DA (described later) side of the engagement portion 33. The contact surface 36 extends along the radial direction of a circle centered on the first support shaft 54. That is, when a pressing force is applied to the contact surface 36, the rotation of the latch 30 is stopped.

  The latch 30 is urged by the urging member 60 in a direction in which the engagement recess 32 faces rearward (hereinafter referred to as “latch urging direction DA”). That is, the latch 30 is biased toward the engageable position (see later). In the door lock device 20 attached to the right rear slide door 2 in the vehicle 1 as in this embodiment, the latch biasing direction DA is the left rotation direction in plan view (see FIG. 4).

  In FIG. 4, the latch 30 and the lock member 40 are engaged, and the engagement recess 32 of the latch 30 faces forward, but the latch 30 is attached when the engagement with the lock member 40 is released. Due to the urging by the urging member 60, the engaging recess 32 faces rearward. Thereby, when the slide door 2 moves backward, the striker 4 is smoothly inserted into the engagement recess 32. In this way, the position where the latch 30 can engage with the striker 4 when the engaging recess 32 of the latch 30 faces rearward is referred to as an “engageable position” (see the two-dot chain line in FIG. 4). ).

The lock member 40 is disposed outside the vehicle width with respect to the latch 30.
The lock member 40 includes a bearing portion 41 supported by the second support shaft 55, a trunk portion 42 extending from the bearing portion 41, and a hook portion 43 that protrudes from the distal end portion of the trunk portion 42 and engages with the engaging portion 33 of the latch 30. And a connecting portion 44 that extends in a direction opposite to the extending direction of the hook portion 43 and to which the inner cable 71 is connected.

  The lock member 40 is urged by the urging member 60 in a direction in which the hook portion 43 faces the engaging portion 33 of the latch 30 (hereinafter referred to as “lock urging direction DB”). That is, the lock member 40 is urged by the urging member 60 so as to be directed to an engagement position (described later). In the door lock device 20 attached to the right rear slide door 2 (see FIG. 1) in the vehicle 1 as in the present embodiment, the lock biasing direction DB is the left rotation direction in plan view (see FIG. 4). That is, the latch biasing direction DA and the lock biasing direction DB are biased to rotate in the same direction.

  The trunk | drum 42 has the 1st side 42a by the side of the lock energizing direction DB, and the 2nd side 42b by the side opposite to the lock energizing direction DB. A contact portion 45 that contacts the engaging portion 33 of the latch 30 is provided on the first side surface 42a. The second side surface 42b is provided with a locking projection 46 on which the end 64 on the second coil portion 62 side of the biasing member 60 is engaged.

The hook part 43 protrudes in the lock urging direction DB.
The hook portion 43 has a hook surface 43 a that contacts the contact surface 36 of the latch 30. The hook surface 43 a faces the second support shaft 55. When the lock member 40 engages with the latch 30, the contact portion 45 of the lock member 40 contacts the side surface 37 of the engagement portion 33 of the latch 30, and the hook surface 43 a contacts the contact surface 36 of the latch 30. . At this time, the force applied to the hook surface 43a of the hook portion 43 due to the engagement with the latch 30 is directed in the radial direction of the second support shaft 55, so that the engagement portion 33 of the latch 30 and the hook portion 43 of the lock member 40 The engagement prevents rotation of the latch 30. Thus, the position of the lock member 40 when the engagement portion 33 of the latch 30 and the lock member 40 are engaged is referred to as an “engagement position” (see FIG. 4).

  When the inner cable 71 is pulled in a state where the latch 30 and the lock member 40 are engaged, the lock member 40 rotates in a direction opposite to the lock urging direction DB, and from the engaging portion 33 of the latch 30. Since the hook portion 43 of the lock member 40 is separated, the engagement between the latch 30 and the lock member 40 is released. And the latch 30 becomes rotatable.

The urging member 60 urges the latch 30 toward the engageable position (see the two-dot chain line in FIG. 4) and urges the lock member 40 toward the engagement position (see FIG. 4). .
The urging member 60 is configured by a spring member having a first coil portion 61 and a second coil portion 62. The spring member is formed of one wire. The first coil part 61 and the second coil part 62 are connected via a connecting part 65. The winding direction of the first coil unit 61 and the winding direction of the second coil unit 62 are opposite. With this configuration, the direction of the urging force formed by the first coil portion 61 (that is, the latch urging direction DA) and the direction of the urging force formed by the second coil portion 62 (that is, the lock urging direction DB) are determined. In the same direction.

The first coil portion 61 is inserted through a first support shaft 54 that is a shaft that supports the latch 30.
The second coil portion 62 is inserted through a second support shaft 55 that is a shaft that supports the lock member 40.
The end portion 63 on the first coil portion 61 side is hooked on the latch 30 so that the latch 30 is biased toward the engageable position. Specifically, as shown in FIG. 4, the end portion 63 on the first coil portion 61 side is a side surface 30a of the latch 30 (a surface on the opposite side to the surface on the latch biasing direction DA side in the first arm 34). ). As a result, the latch 30 is biased in the latch biasing direction DA.

  The end portion 64 on the second coil portion 62 side is hooked on the locking projection 46 of the lock member 40 so that the lock member 40 is biased toward the engagement position. As a result, the lock member 40 is urged in the lock urging direction DB. When a force that resists the lock biasing direction DB is not applied to the lock member 40, the lock member 40 rotates in the lock biasing direction DB, and the contact portion 45 of the lock member 40 is engaged with the engagement portion 33 of the latch 30. The hook portion 43 is brought into contact with the side surface 37 and the hook portion 43 is hooked on the corner portion of the engaging portion 33, so that the hook surface 43 a and the contact surface 36 of the engaging portion 33 come into contact with each other.

Further, the end portion 63 on the first coil portion 61 side has the following configuration.
The door lock device 20 is assembled as described later, but the end portion 63 on the first coil portion 61 side is configured as follows so as to facilitate assembly.

  That is, the urging member 60 is attached to the support member 50, the lock member 40 is disposed so that a space for the latch 30 is disposed, and the first coil portion 61 is hidden by the latch 30 being disposed in the space. In some cases, the end 63 on the first coil portion 61 side is configured to protrude from the latch 30 (see FIG. 6C).

Next, the arrangement of the urging member 60 and the latch 30 and the lock member 40 and the support member 50 will be described.
The urging member 60, the latch 30, and the lock member 40 have the following arrangement relationship. When the sliding door guide device 10 is attached to the vehicle 1, the latch 30 and the lock member 40 are disposed on the biasing member 60. Specifically, the latch 30 is disposed above the first coil portion 61, and the lock member 40 is disposed above the second coil portion 62. Hereinafter, the arrangement structure in which the latch 30 is arranged on the upper side of the urging member 60 in this way is referred to as an “on-latch arrangement structure”.

The operation of the on-latch arrangement structure will be described with reference to FIG.
5 (a) and 5 (b) are enlarged views of the rear lower end of the entrance / exit 1a (the portion hidden in the front lower corner of the sliding door 2 in FIG. 1), and the sliding door 2 is the rearmost. The figure when it is arrange | positioned at the side and the door lock apparatus 20 is engaging with the striker 4 is shown. In this figure, the slide door guide device 10 has a cut surface cut along a plane including the entrance 1a (a plane outside the guide rail 3 and inside the outer panel of the slide door 2 in the vehicle width direction). It is shown.

  As in the example shown in FIG. 5, the striker 4 may be disposed below the guide rail 3 and inside the entrance 1 a of the vehicle 1. In the case of such a configuration, the striker 4 is disposed in front of the bent corner portion 1b of the entrance / exit 1a so that the bracket 11 of the slide door guide device 10 does not contact the peripheral edge of the entrance / exit 1a. Moreover, since it is preferable that the opening area of the entrance / exit 1a when the entrance / exit 1a is opened (area of the opening part where a person gets on / off) is wide from the ease of getting on / off, the striker 4 is as much as possible. It is arranged behind 1a.

  FIG. 5A shows that the door lock device 20 having a comparative structure in which the latch 30 is disposed below the urging member 60 is used for the slide door guide device 10 instead of the above-described structure on the latch. The arrangement | positioning of the striker 4 in the entrance / exit 1a when there exists is shown. The length of the striker 4 in the vertical direction is set to a length with which the latch 30 can be engaged.

  In the on-latch arrangement structure, the latch 30 is arranged on the upper side of the support member 50 as compared with the comparative structure (the structure shown in FIG. 5A). For this reason, in the striker 4, the length of the lower part than the latch 30 becomes extra. That is, according to the arrangement structure on the latch, the length of the striker 4 in the vertical direction can be shortened.

  FIG. 5B shows the arrangement of the strikers 4 at the entrance / exit 1a when the door lock device 20 having the above-latch arrangement structure is used in the sliding door guide device 10. FIG. In this example, the length of the striker 4 in the vertical direction is shorter than that of the comparative structure, and the striker 4 is shifted to the bent corner portion 1b side of the entrance / exit 1a.

  That is, according to the on-latch arrangement structure, the length of the striker 4 in the vertical direction can be shortened as described above. As a result, the striker 4 can be brought closer to the bent corner portion 1b of the entrance / exit 1a, and the striker 4 can be disposed further rearward. Thereby, the opening area of the entrance / exit 1a of the slide door 2 can be enlarged. Moreover, since it is possible to shorten the length of the striker 4 in the vertical direction by the arrangement structure on the latch, the installation position of the guide rail 3 is arranged below, and the height of the lower edge of the entrance / exit 1a is lowered. Can do. This makes it easy for people to get in and out of the passenger compartment.

Next, a method for assembling the door lock device 20 will be described with reference to FIG.
As shown in FIG. 6A, in the first step, the support member 50 is inserted such that the first coil portion 61 is inserted through the first support shaft 54 and the second coil portion 62 is inserted through the second support shaft 55. The urging member 60 is attached to.

  As shown in FIG. 6B, in the second step, the lock member 40 is disposed on the second coil portion 62, and the end portion 64 on the second coil portion 62 side is connected to the locking projection portion of the lock member 40. 46 is engaged.

  As shown in FIG. 6C, in the third step, the lock member 40 is rotated so that a space in which the latch 30 is disposed is free. Specifically, the lock member 40 is rotated in a direction opposite to the lock urging direction DB. Then, the latch 30 is disposed in a space generated by the rotation of the lock member 40. At this time, the latch 30 is arranged in the space to hide the first coil, but the end 63 on the first coil portion 61 side protrudes from the latch 30.

  As shown in FIG. 6D, in the fourth step, the latch 30 is rotated so that the latch 30 and the lock member 40 are engaged. Specifically, the latch 30 is rotated in the direction opposite to the latch biasing direction DA. When the latch 30 is rotated in this way, the end portion 63 on the first coil portion 61 side is engaged with the side surface 30 a of the first arm 34 of the latch 30.

Next, the operation of the door lock device 20 according to this embodiment will be described.
The conventional door lock device 20 has a biasing member 60 for biasing the latch 30 and a biasing member 60 for biasing the lock member 40 separately. On the other hand, in the door lock device 20 according to the present embodiment, the urging of the latch 30 and the urging of the lock member 40 are performed by one urging member 60. For this reason, the number of parts is smaller than that of the door lock device 20 having the conventional structure. Moreover, according to such a structure, attachment becomes easy. Since the conventional door lock device 20 has two urging members 60, it is necessary to engage each of the two ends of each urging member 60 at a predetermined position. That is, in the conventional door lock device 20, the operation of engaging the end portion of the urging member 60 with a predetermined location is performed four times in the assembly process. In this regard, in the door lock device 20 according to the present embodiment, since there is one urging member 60, the work of engaging the end portions 63 and 64 of the urging member 60 at a predetermined position is sufficient. Thus, according to the door lock device 20 according to the present embodiment, the assembly process is simplified.

Hereinafter, effects of the door lock device 20 according to the present embodiment will be described.
(1) In the present embodiment, the door lock device 20 includes a latch 30, a lock member 40, and a biasing member 60 that biases the latch 30 and the lock member 40. The urging member 60 urges the latch 30 so that the latch 30 moves toward the engageable position where the latch 30 can engage with the striker 4, and locks the lock member 40 toward the engaging position where the lock member 40 engages with the latch 30. The member 40 is biased.

  According to this configuration, the latch 30 and the lock member 40 are urged by the single urging member 60. For this reason, compared with the conventional structure in which the urging member 60 is provided for each of the latch 30 and the lock member 40, the number of parts is small.

  (2) In the present embodiment, the urging member 60 is a spring member having a first coil portion 61 and a second coil portion 62. The first coil portion 61 is inserted through a first support shaft 54 that is a shaft that supports the latch 30. The second coil portion 62 is inserted through a second support shaft 55 that is a shaft that supports the lock member 40. The end portion 63 on the first coil portion 61 side is hooked on the latch 30 so that the latch 30 is biased toward the engageable position. The end portion 64 on the second coil portion 62 side is hooked on the lock member 40 so that the lock member 40 is biased toward the engagement position.

  According to this configuration, since the first coil portion 61 of the urging member 60 is inserted through the first support shaft 54 and the second coil portion 62 is inserted through the second support shaft 55, the first coil portion 61 is The number of support shafts is reduced as compared to a structure supported by another support shaft or a structure in which the second coil portion 62 is supported by another support shaft. Thereby, compared with these comparative structures, the door lock device 20 becomes small.

  (3) In the present embodiment, in the arrangement of the door lock device 20 when attached to the slide door 2 of the vehicle 1 via the bracket 11, the latch 30 is arranged above the first coil portion 61, and the second coil The lock member 40 is disposed on the upper side of the portion 62.

  The door lock device 20 is attached to the door of the vehicle 1 via the bracket 11. According to the above-described configuration in the arrangement of the door lock device 20 when attached to the door of the vehicle 1, the latch 30 is arranged below the first coil portion 61 and locked below the second coil portion 62. Compared to the structure in which the member 40 is disposed, the latch 30 and the lock member 40 are disposed on the upper side in the bracket 11. Then, the length of the striker 4 that engages with the latch 30 in the vertical direction can be shortened, whereby the striker 4 can be brought closer to the bent corner 1b on the rear side of the entrance 1a. . Thereby, the opening area of the entrance 1a of the slide door 2 can be expanded. That is, the door lock device 20 having the above-described configuration enables the striker 4 to be further arranged rearward, thereby enabling the opening area of the entrance / exit 1a of the slide door 2 to be increased. Moreover, since the installation position of the guide rail 3 can be arrange | positioned below and the height of the lower edge of the entrance / exit 1a can be made low, a passenger's boarding / alighting in a vehicle interior becomes easy.

  (4) In this embodiment, the biasing member 60 is attached to the support member 50 so that the first coil portion 61 is inserted through the first support shaft 54 and the second coil portion 62 is inserted through the second support shaft 55. . Then, the lock member 40 is disposed on the second coil portion 62 so that a space for the latch 30 is disposed, and the latch 30 is disposed in the space. At this time, the first coil is hidden, but the end 63 on the first coil portion 61 side protrudes from the latch 30.

  According to this configuration, even when the first coil unit 61 is hidden by arranging the latch 30 in the space, the end 63 on the first coil unit 61 side protrudes from the latch 30. That is, since the end portion 63 on the first coil portion 61 side is not hidden by the latch 30, it is easy to hang the end portion 63 on the first coil portion 61 side on the latch 30 in assembling the door lock device 20. Become.

  (5) The slide door guide device 10 according to the present embodiment includes a roller unit 15 that slides on the guide rail 3 of the vehicle 1 and a door lock device 20. Since the slide door guide device 10 having this configuration includes the door lock device 20, the number of parts is small.
