Description

  The present invention relates to a door check mechanism for a vehicle door.

  A general vehicle door is pivotally connected to a vehicle body via a door hinge on one side, and is fully opened or half-opened by a door check mechanism provided between the side and the vehicle. The predetermined opening (opening operation position) can be maintained.

  However, maintaining the door opening by the conventional door check mechanism, particularly maintaining the half-opening opening, does not prevent the door from opening more than the opening. Therefore, even when a force in the opening direction is applied to the door held at the half-opening position against the user's intention, the door cannot be opened by the conventional door check mechanism. In some cases, the door hits an obstacle on the side of the vehicle.

  Therefore, as shown in Patent Document 1, a tightening mechanism having a clamping piece for clamping the check link of the door check mechanism adds a movement restraining force to the check link to prevent the check link from moving, and the door opening degree There has been proposed a door check mechanism for fixing the door.

  In addition, a door check mechanism that limits the opening of the door with a simpler configuration has been proposed. For example, a block that rotates with respect to the check link is provided, the block is rotated, and placed between the door check and the stopper part of the check link, so that the movement of the check link is limited, and the opening of the door is increased. Limiting door check mechanisms have also been proposed.

  However, in such a door check mechanism using a rotating block, when the opening degree of the door is limited by the block, the block is used as a door check and a check link stopper to limit the movement of the check link. It is caught. When the block is sandwiched between the door check and check link stoppers, the block is blocked by the door check and check link stoppers, and the movement of the block in the rotational direction by contacting the stoppers is restricted. Cannot rotate. That is, when the door is opened to a limited opening, the user cannot operate the operation unit connected to the block and move the block. However, in such a case, there is a possibility that the user tries to rotate the block in order to change the opening degree of the door, and forcibly operates the operation unit of the door check mechanism for rotating the block. was there.

  When the user tries to forcefully operate the operation part of the door check mechanism in a state in which the block cannot rotate, an excessive force is applied to the operation part or the block, which may damage the part.

  The opening adjustment device 10 is provided with a door check (movement restriction member) 11, a check link 12, a check stopper portion 13, a bracket 14, an opening adjustment block 15, and a connection member 16.

  As shown in FIG. 1, the door check 11 is attached to the door D via a fixing member (not shown) and the check link 12 is arranged to extend inside the door D via the door check 11. . Further, the door check 11 is provided with a rotation shaft 111 of the opening adjustment block 15.

  One end of the check link 12 is rotatably attached to the vehicle body via a bracket 14 coupled to the vehicle body. The check link 12 extends through the door check 11 and into the door D. A check stopper portion 13 is provided at the other end portion of the check link 12 extending inside the door D.

  The check link 12 rotates with respect to the vehicle body as the door D rotates. When the door D is opened and closed, the door D moves in a direction away from or closer to the vehicle body based on the rotation of the door D. Therefore, the check link 12 attached to the vehicle body is rotated based on the rotation of the door D, and when the door D is opened, the check link 12 is pulled out from the inside of the door D that moves away from the vehicle body. When the door D is closed, the check link 12 is inserted into the door D that moves in a direction approaching the vehicle body. Thereby, when the door D rotates, the check link 12 can move in the length direction of the check link 12 relative to the door check 11 attached to the door D.

  When the door D is opened, the check link 12 is pulled out from the door D as the door D rotates, and moves to the one end side attached to the vehicle body of the check link 12 with respect to the door check 11. The check stopper portion 13 moves toward the door check 11 by moving the check link 12 toward one end attached to the vehicle body. When the check stopper portion 13 comes into contact with the door check 11, the movement of the check link 12 toward the one end is restricted, and the check link 12 is further restricted from being pulled out from the door D. When the movement, that is, the rotation of the check link 12 is restricted, the rotation of the door D is also restricted. Therefore, the opening degree of the door D is restricted based on the restriction of the movement of the check link 12. Here, the opening degree of the door D when the check stopper portion 13 abuts on the door check 11 is the fully open opening degree of the door D.

At this time, since the second contact portion 152 is provided so as to face the first contact portion 151 as described above, the check stopper portion 13 provided to contact the door check 11 and Face each other. Therefore, when the door D is opened when the opening adjustment block 15 moves to the position, the check link 12 moves to one end side attached to the vehicle body, and the check stopper portion 13 is moved to the second contact portion 152. Will abut. Accordingly, the opening adjustment block 15 is sandwiched between the door check 11 and the check stopper portion 13 and restricts the check link 12 from moving toward one end portion attached to the vehicle body. As a result, the rotation of the door D accompanying the movement of the check link 12 is also restricted, so that the opening of the door D is made according to the length of the opening adjustment block 15 sandwiched between the door check 11 and the check stopper portion 13. The degree can be limited.

  The opening adjustment block 15 is connected to the operating device 20 via the connection members 16 and 21 and the urging unit 17, and rotates about the rotating shaft 111 based on the operation of the operating device 20 by the user. To do.

The connecting member 16 connects the opening adjustment block 15 and the lever 22 together with the urging portion 17 and the connecting member 21. The connecting member 16 may be connected to the opening adjustment block 15 via an arbitrary arm member (not shown) provided in the opening adjustment block 15.

  The biasing part 17 is comprised from arbitrary elastic members, such as a spring and rubber | gum, and can be comprised so that it can expand | stretch (deform) in the extending direction. Further, the urging unit 17 may be configured by a pneumatic cylinder or a hydraulic cylinder configured to be able to extend (deform) in the extending direction. The urging unit 17 is connected to the connection member 16 connected to the opening adjustment block 15 and the connection member 21 connected to the lever 22 of the operation device 20, and is connected to the opening adjustment block 15 and the lever 22 of the operation device 20. Connect between them. Further, the urging unit 17 urges the lever 22 and the opening adjustment block 15 connected via the connection members 16 and 21 in a direction approaching each other. When the opening adjustment block 15 is rotated according to the movement of the lever 22, the urging unit 17 moves along with the movement of the lever 22 together with the connection members 16 and 21.

  The operating device 20 includes a connecting member 21 connected to the opening adjustment block 15 via the connecting member 16 and the urging unit 17, a lever 22 (operating unit) to which the connecting member 21 is connected, a base 23, Is provided.

  The connection member 21 can be configured using any member including, for example, a wire, a cable, a rod-shaped member (rod), and the like. The connecting member 16 connected to the opening adjustment block 15, the connecting member 21 connected to the lever 22, and the urging portion 17 connected to the connecting members 16, 21 move with the movement of the lever 22 to open the opening. The adjustment block 15 can be moved. The connecting member 21 may be connected to the lever 22 via an arbitrary arm member (not shown) provided on the lever 22. Further, the connection members 16 and 21 and the urging portion 17 may be supported by an arbitrary connection member support portion fixed to the door D, the base 23, or the like and may be oriented in the extending direction.

  The lever 22 is provided with a connecting portion 221 connected to the connecting member 21, a rotating shaft 222 that passes through the rotation center point, and a knob 223 that is an operation part operated by the user. The lever 22 is connected to the rotation shaft 222 so as to be rotatable about the rotation shaft 222, and the rotation shaft 222 is connected to the base 23. The rotation shaft 222 may be formed integrally with the lever 22, and in this case, the rotation shaft 222 is rotatably connected to the base 23.

  The knob 223 is connected to the lever 22, and the user can rotate the lever 22 about the rotation shaft 222 by moving the knob 223. The knob 223 may be formed integrally with the lever 22 or may be formed as a separate member and connected to the lever 22. The knob 223 can be provided at an arbitrary position of the lever 22. For example, the knob may be provided at an end away from the rotation shaft 222 as illustrated, or may be provided at a portion closer to the rotation shaft 222. When the lever 22 is formed integrally with the rotating shaft 222, the knob may be provided on the rotating shaft 222. In this case, the user rotates the knob to move the lever 22. It can be rotated.

  The base 23 is coupled to the door D via an arbitrary fixing member such as a bolt. The base 23 is provided with a first stopper portion 231 and a second stopper portion 232. When the opening adjustment block 15 is disposed at a position that restricts the opening degree of the door D, the first stopper portion 231 contacts the lever 22 and restricts the rotation of the lever 22, and the opening degree of the door D is reduced. The lever 22 is held at an operation position (hereinafter, limited operation position) corresponding to the position to be limited. When the opening degree adjustment block 15 is arranged at a position where the opening degree of the door D is not limited, the second stopper portion 232 abuts on the lever 22 to regulate the rotation of the lever 22 and to set the opening degree of the door D. The lever 22 is held at an operation position (hereinafter, fully open operation position) corresponding to the position set to the fully open position. The stopper portions 231 and 232 can have any shape as long as they can contact the lever 22.

  Next, operation | movement of the opening degree adjustment apparatus 10 is demonstrated using FIG. 3A and B. FIG. 3A and 3B show the operation of the opening adjustment device 10. 3A shows the opening adjustment device 10 when the opening degree of the door D is set to the fully open opening degree, and FIG. 3B shows the movement of the opening adjustment device 10 when the opening degree of the door D is limited. In FIG. 3B, the opening degree adjustment block 15 and the connecting member 16 shown in FIG. 3A are indicated by a two-dot chain line. In FIGS. 3A and 3B, the bracket 14 is omitted for simplification of description.

  When the opening degree of the door D is set so that the door D can be rotated to the full opening degree without restricting the opening degree of the door D, as shown in FIG. The adjustment block 15 is disposed above the check link 12. At this time, the first contact portion 151 does not contact the door check 11, and the second contact portion 152 does not contact the check stopper portion 13. Further, the check stopper portion 13 is attached to the vehicle body of the check link 12 without contacting the opening adjustment block 15 when the check link 12 moves in accordance with the opening operation of the door D. To contact the door check 11. Therefore, the door D can be rotated to the fully open position.

  Next, when the user operates the operation device 20 to limit the opening degree of the door D, the opening adjustment block 15 is shown in FIG. 3A indicated by a two-dot chain line, as shown in FIG. It rotates from the position of the opening adjustment block 15 in the direction (downward) indicated by the arrow A1. When the opening adjustment block 15 rotates in the direction toward the position between the door check 11 and the check stopper portion 13 along the direction indicated by the arrow A1, the first contact portion 151 contacts the door check 11. . When the opening adjustment block 15 rotates to a position where the first contact portion 151 contacts the door check 11, the opening adjustment block 15 moves between the door check 11 and the check stopper portion 13. At this time, since the first contact portion 151 contacts the door check 11, the second contact portion 152 that faces the first contact portion 151 faces the check stopper portion 13 that faces the door check 11.

  As shown in FIG. 3B, the opening adjustment block 15 includes a first contact portion 151 having a predetermined length in the longitudinal direction of the check link 12 in the vicinity of the rotation shaft 111 of the opening adjustment block 15. A cutout portion 153 is provided so as to cut out only. For this reason, the load when the opening adjustment block 15 rotates to the position between the door check 11 and the check stopper portion 13 and the first contact portion 151 contacts the door check 11 is applied to the rotation shaft 111. It is possible to avoid concentrating on the portion of the first contact portion 151 in the vicinity. Therefore, damage to the opening adjustment block 15 due to a load when the first contact portion 151 contacts the door check 11 can be suppressed.

  When the door D is opened after the opening adjustment block 15 is rotated to the position shown in FIG. 3B, the check link 12 moves to one end side attached to the vehicle body, and the check link 12 moves along with the check link 12. The stopper part 13 moves. Here, since the opening adjustment block 15 is arranged so that the second contact portion 152 faces the check stopper portion 13 as described above, the check stopper portion 13 is moved based on the movement of the check stopper portion 13. It contacts the second contact portion 152. Since the opening adjustment block 15 is in contact with the door check 11 at the first contact portion 151, movement of the check link 12 toward one end attached to the vehicle body is limited. Accordingly, the opening adjustment block 15 is sandwiched between the door check 11 and the check stopper portion 13, and the opening adjustment block 15 is attached to the vehicle body of the check link 12 to the check stopper portion 13 and the check link on the one end side. Limit 12 movements. Thereby, the movement of the check link 12 is restricted, and the rotation of the door D in the opening direction is restricted. Therefore, the opening degree of the door D can be limited by rotating the opening degree adjusting block 15 and disposing it between the door check 11 and the check stopper portion 13.

  As described above, the opening adjustment device 10 according to the present embodiment includes the door check 11 attached to the vehicle door D, and one end portion rotatably attached to the vehicle body and extending inside the vehicle door D. And a check stopper portion 13 provided at the other end of the check link 12 extending inside the vehicle door D. The check link 12 can move in the longitudinal direction of the check link 12 relative to the door check 11 based on the rotation of the door D. The opening adjustment device 10 further includes an opening adjustment block 15 that rotates with respect to the check link 12. The opening adjustment block 15 has a first contact portion 151 that contacts the door check 11, a first contact portion 151 that faces the first contact portion 151, and has a predetermined distance from the first contact portion 151. A second contact portion 152 that contacts the stopper portion 13 is included. When the opening adjustment block 15 rotates toward the check link 12 and the first contact portion 151 comes into contact with the door check 11, the opening adjustment block 15 is attached to the vehicle body of the check link 12. It is restricted to move to. When the movement of the opening adjustment block 15 to the one end side of the check link 12 is restricted and the check stopper portion 13 comes into contact with the second contact portion 152, the opening adjustment block 15 moves to one end of the check link 12. The movement of the check link 12 to the department side is restricted.

  As a result, the movement of the check link 12 toward the one end portion attached to the vehicle body of the check link 12 is limited by the opening adjustment block 15, so that an external force in the opening operation direction is unintentionally applied to the door D. Even if it is a case, it can prevent that the door D opens. Note that the restriction on the opening degree of the door D restricts only the door D from rotating in the opening direction from the restricted opening degree. Therefore, the door D is in the range from the opening degree to the fully closed position. It can rotate freely. Further, since the opening adjustment block 15 moves between the door check 11 and the check stopper portion 13 by rotating, the position of the opening adjustment block 15 relative to the door check 11 or the check stopper portion 13 is moved. A shift or the like can be prevented.

  Here, when the opening adjustment block 15 is disposed between the door check 11 and the check stopper portion 13 and restricts the opening of the door D, the opening adjustment block 15 includes the door check 11 and the check stopper. Since it is pinched by the part 13, it cannot rotate. In particular, in order for the opening adjustment block 15 to rotate when the opening adjustment block 15 is disposed at a position in contact with the door check 11, the opening adjustment block 15 is rotated with the check stopper 13 side. It is necessary to move to. Therefore, when the opening adjustment block 15 contacts the check stopper portion 13, the rotation of the opening adjustment block 15 is restricted. In this case, if the opening adjustment block 15 and the operating device 20 are connected only by a rigid connecting member that cannot be extended (deformed), the rotation of the opening adjustment block 15 is restricted. As a result, the movement of the connecting member and the operation of the operating device 20 are also restricted. However, since the opening adjustment block 15 operates in the door D, the operation of the opening adjustment block 15 is not visible to the user. Therefore, even though the operation of the operation device 20 is restricted, the user may not be aware of it and may try to operate the operation device 20 forcibly. In this case, since an excessive load is applied to the operating device 20, the operating device 20, the connection member, or the like may be damaged.

  On the other hand, in the door check mechanism 1 according to the present embodiment, the opening adjustment block 15 and the lever 22 are connected via an urging portion 17 formed of an elastic member. Therefore, even when the opening adjustment block 15 is sandwiched between the door check 11 and the check stopper portion 13 and the rotation is restricted, the lever 22 extends (deforms) the biasing portion 17 according to the user's operation. ). Therefore, even in such a case, the user can operate the operating device 20 without difficulty, and the user is prevented from applying an excessive load to the operating device 20, and the operating device 20 and the connection member are damaged. Can be suppressed.

  The operations of the opening adjustment block 15, the urging unit 17, and the operating device 20 in the door check mechanism 1 according to this embodiment will be described with reference to FIGS. FIG. 4A shows the opening adjustment block 15, the urging unit 17, and the operating device 20 when the opening adjustment block 15 is arranged at a position where the opening of the door D is limited. FIG. 4B shows the opening adjustment block 15, the urging unit 17, and the operating device 20 when the opening adjustment block 15 is arranged at a position where the opening of the door D is set to the fully open position. 4C, the opening adjustment block 15 is arranged at a position where the opening degree of the door D is restricted, and the opening degree adjustment block 15, the urging unit 17 and the operating device when the door D is opened to the opening degree that is restricted. 20 is shown. FIG. 4D shows a case where the opening adjustment block 15 is arranged at a position where the opening degree of the door D is restricted, and the operation device 20 is moved to the fully opened operation position when the door D is opened to the opening degree. The opening adjustment block 15, the urging | biasing part 17, and the operating device 20 are shown. 4A and 4B, a virtual line VL passing through the connection portion 154 of the opening adjustment block 15 and the rotation center point of the lever 22 is indicated by a two-dot chain line. 4A to 4D, the bracket 14, the door D, the base 23, and the bearing portion of the rotating shaft 111 provided on the door check 11 are omitted for simplification of description.

  When the opening adjustment block 15 is arranged at a position that restricts the opening of the door D, the opening adjustment block 15 is provided between the door check 11 and the check stopper portion 13 as shown in FIG. 4A. Be placed. The lever 22 is held at the restricting operation position. In the restricting operation position, the first stopper portion 231 contacts and holds the lever 22. When the opening adjustment block 15 is disposed at a position that restricts the opening of the door D, the check stopper portion 13 moves in the extending direction of the check link 12 to a position where it comes into contact with the opening adjustment block 15. be able to. Therefore, the user can freely open the door D to the opening degree limited by the opening degree adjustment block 15.

  Next, as shown in FIG. 4B, the user moves the lever 22 of the operation device 20 to the fully open operation position. In this case, the connection members 16 and 21 and the urging portion 17 move in accordance with the movement of the lever 22 and rotate the opening adjustment block 15 upward about the rotation shaft 111. In the fully open operation position, the second stopper portion 232 contacts and holds the lever 22. When the opening adjustment block 15 is disposed at a position where the opening degree of the door D is set to the fully open opening degree, the check stopper portion 13 does not contact the opening adjustment block 15 and the check link 12 extends. Can move in the direction. Therefore, the user can open the door D freely to the fully open position.

  On the other hand, when the opening adjustment block 15 is arranged at a position where the opening degree of the door D is restricted, when the door D is opened to an opening degree where the opening degree is restricted, as shown in FIG. 13 moves to a position where it contacts the second contact portion 152 of the opening adjustment block 15. In this case, the opening adjustment block 15 is sandwiched between the door check 11 and the check stopper portion 13, thereby restricting the movement of the check link 12 toward the one end attached to the vehicle body. Further, the check stopper portion 13 abuts on the second abutting portion 152, and the door check 11 and the check stopper portion 13 sandwich the opening adjustment block 15, thereby restricting the rotation of the opening adjustment block 15. The

  In this case, even if the user tries to move the lever 22 to the fully open operation position, the opening adjustment block 15 is moved with the movement of the lever 22 because the rotation of the opening adjustment block 15 is restricted. I can't. Therefore, when the lever 22 moves to the fully open operation position, the distance between the lever 22 and the opening adjustment block 15 at the position where the opening degree of the door D is limited, in particular, the connection portion 154 is moved. The distance between the knob 223 (operation part) and the connection portion 221 is increased. Therefore, if the opening adjustment block 15 and the lever 22 are connected by a rigid connecting member, the distance between the opening adjustment block 15 and the lever 22 cannot be changed, and therefore the movement of the lever 22 is also restricted. The

  On the other hand, in the door check mechanism 1 according to the present embodiment, the opening adjustment block 15 and the lever 22 are connected using the urging unit 17. The urging unit 17 is configured to be extendable in the extending direction, and when the distance between the opening adjustment block 15 and the lever 22 increases as the lever 22 moves, the opening adjustment block 15 and the lever 22 are Stretch between. Therefore, even when the distance between the opening adjustment block 15 and the lever 22 increases as the lever 22 moves, the biasing portion 17 extends as shown in FIG. The lever 22 can move while maintaining the connection with the lever 22. Thereby, even if the opening adjustment block 15 is sandwiched between the door check 11 and the check stopper portion 13 and the rotation is restricted, the user cannot push the lever 22 connected to the opening adjustment block 15. You can operate and move without. Therefore, it is possible to prevent the user from applying an excessive load to the operation device 20 and to prevent the operation device 20 and the connection member from being damaged.

  When the lever 22 moves in a direction away from the opening adjustment block 15 while extending the urging portion 17 and then rotates in the direction in which the door D is closed, the check link 12 moves to the check stopper portion 13 side. The check stopper portion 13 is separated from the second contact portion 152. Therefore, the holding of the opening adjustment block 15 by the door check 11 and the check stopper portion 13 is released, and the opening adjustment block 15 can be rotated. Here, the extending urging portion 17 is in a state where an external force is applied in the extending direction in the extending direction along with the movement of the lever 22 and the external force is stored. Therefore, the urging unit 17 applies an external force in a direction in which the urging unit 17 contracts, that is, a direction approaching the lever 22, to the opening adjustment block 15 in accordance with the elastic force based on the stored external force. Energize in that direction. Therefore, the opening adjustment block 15 can be rotated in a direction approaching the lever 22 by urging based on the extension of the urging unit 17. In particular, when the lever 22 has moved to the fully open operation position, the opening adjustment block 15 can be rotated to a position that does not limit the opening of the door D, as shown in FIG. 4B. Thereafter, the opening adjustment block 15 is rotated again with the movement of the lever 22 via the connecting members 16 and 21 and the biasing portion 17.

  In the door check mechanism 1 according to the present embodiment, as described above, the lever 22 that controls the rotation of the opening adjustment block 15, the lever 22 and the opening adjustment block 15 are connected, and the lever 22 and the opening adjustment block 15 are connected. And an urging portion 17 that urges the components in a direction approaching each other. The opening adjustment block 15 rotates based on the movement of the lever 22 connected via the urging unit 17. When the first contact portion 151 of the opening adjustment block 15 contacts the door check 11 and the check stopper portion 13 contacts the second contact portion 152, the lever 22 extends (deforms) the biasing portion 17. And moving in a direction away from the opening adjustment block 15. Thus, even when the opening adjustment block 15 is sandwiched between the door check 11 and the check stopper portion 13 and the rotation of the opening adjustment block 15 is restricted, the user is connected to the opening adjustment block 15. The lever 22 can be operated and moved without difficulty. Therefore, it is possible to prevent the user from applying an excessive load to the operation device 20 and to prevent the operation device 20 and the connection member from being damaged.

  Further, the urging unit 17 may extend to some extent when the opening adjustment block 15 is rotated as the lever 22 moves. Furthermore, in the present embodiment, the urging unit 17 is configured to be extensible, but the configuration of the urging unit 17 is not limited thereto. The urging unit 17 urges the opening adjustment block 15 and the lever 22 in a direction approaching each other, and when the movement of the opening adjustment block 15 is restricted, the opening adjustment block 15 and the lever 22 are deformed by deformation. It is sufficient that the lever 22 can be allowed to move while maintaining the connection. Therefore, the deformation of the urging portion 17 is not limited to expansion / contraction, and may be any form of deformation, for example, bending deformation or twisting deformation.

  Further, in the door check mechanism 1 according to the present embodiment, when the lever 22 moves between the restricting operation position and the fully open operation position, as shown in FIGS. 4A and 4B, the connecting portion 221 of the lever 22 is connected to the virtual line VL. Move beyond. Here, the imaginary line VL is a line passing through the opening adjustment block 15 and the connection part 154 of the connection member 16 and the rotation center point of the lever 22.

  As shown in FIG. 4A, when the lever 22 is in the restricting operation position, the connection portion 221 is located below the rotation center point of the lever 22, and the rotation center point is the connection members 16, 21 and the biasing portion. 17 on the upper side. As shown in FIG. 4B, when the lever 22 is in the fully open operation position, the connection portion 221 is on the upper side with respect to the rotation center point of the lever 22, and the rotation center point is the connection members 16, 21 and the biasing portion 17. On the lower side. When the connection part 221 moves beyond the virtual line VL, the connection part 221 is rotated at the center of rotation based on the tension applied from the opening adjustment block 15 via the connection members 16 and 21 and the urging part 17. The direction of movement is changed with respect to. That is, the turning direction of the lever 22 based on the tension applied from the opening adjustment block 15 via the connecting members 16 and 21 and the urging portion 17 is switched. Note that, at each operation position of the lever 22, the rotation center point may be on the opposite side with respect to the connection members 16, 21 and the urging portion 17. Therefore, for example, the rotation center point is on the left side with respect to the connection members 16 and 21 and the urging portion 17 when in the limit operation position, and the rotation center point is connected with the connection members 16 and 21 and attachment when in the fully open operation position. The operating device 20 may be configured to be on the right side with respect to the urging portion 17.

  In this case, when the lever 22 is not operated by the user, the lever 22 is in the first or second stopper portion 231, 232 at each operation position according to the tension based on the weight of the opening adjustment block 15 from the opening adjustment block 15. It is urged in the direction of abutting. Therefore, the first and second stopper portions 231 and 232 can respectively hold the lever 22 based on the tension applied from the opening adjustment block 15 at the limit operation position and the fully open operation position. Therefore, the door check mechanism 1 can hold the lever 22 at each operation position with a simple configuration, and can hold the operating state of the opening adjustment block 15 according to the position of the lever 22.

The rotation direction of the opening adjustment block 15 may be a direction in which the opening adjustment block 15 can rotate between a position sandwiched between the door check 11 and the check stopper portion 13 and a position not sandwiched between them. The direction of the moving axis can also be an arbitrary direction depending on the rotation direction. Therefore, for example, the opening adjustment block 15 may be provided below the check link 12 and configured to move toward the check link 12 by rotating upward. Further, the opening adjustment block 15 may be provided on the side of the check link 12 and configured to move toward the check link 12 by rotating leftward or rightward.

  Further, the biasing member (not shown) including, for example, a spring or rubber can be provided on the connection member 16 connected to the opening adjustment block 15. The urging member can urge the opening adjustment block 15 toward a position adjacent to the check link 12, that is, a position between the door check 11 and the check stopper portion 13. In this case, the biasing member is a direction in which the first contact portion 151 contacts the door check 11 when the opening adjustment block 15 is disposed at a position between the door check 11 and the check stopper portion 13. The opening adjustment block 15 can be biased. Thereby, when the opening adjustment block 15 is arranged at the position, the urging member presses the opening adjustment block 15 against the door check 11, so that the opening adjustment block 15 caused by vibration or the like during traveling of the vehicle. It is possible to prevent rattling and the like. In this case, the urging member opens the external force so that the lever 22 can move while the urging portion 17 extends even when the opening adjustment block 15 is sandwiched between the door check 11 and the check stopper portion 13. It can be applied to the adjustment block 15.

  In this embodiment, the opening adjustment block 15 and the lever 22 are connected using the connecting members 16 and 21 in addition to the biasing portion 17, but the biasing portion 17 is not used without using the connecting members 16 and 21.

The opening adjustment block 35 can rotate around the rotation shaft 111 provided in the door check 11 by passing the rotation shaft 111 through the hole 355. Similar to the opening adjustment block 15, the opening adjustment block 35 rotates with respect to the check link 12, the first contact portion 351 contacts the door check 11, and the second contact portion 352 checks. The movement of the check link 12 is limited by contacting the stopper portion 13. Therefore, the opening degree of the door D can be limited by using the opening degree adjustment block 35.

  The urging portion 37 is composed of an arbitrary elastic member such as a spring or rubber, and can be configured to be extended (deformed) in the extending direction. The biasing portion 37 is connected to the connection portion 354 of the opening adjustment block 35 and the connection portion 421 of the lever 42 of the operating device 40, and extends between the opening adjustment block 35 and the lever 42 of the operating device 40. Connect these. Further, the urging unit 37 urges the lever 42 and the opening adjustment block 35 in a direction approaching each other. The urging unit 37 connects the opening adjustment block 35 and the lever 42 and urges them in a direction approaching each other, so that the opening adjustment block 35 can be rotated according to the rotation of the lever 42.

  The urging portion 38 can be formed of an elastic member such as a torsion coil spring. The urging portion 38 is provided coaxially with the rotation shaft 111, and is mutually connected to the opening adjustment block 35 and the lever 42 of the operating device 40 that are connected to each other via the rotation shaft 111. An external force is applied in the direction of leaving. When the lever 42 is in the restricting operation position, the urging unit 38 applies the opening adjustment block 35 in the direction toward the door check 11, that is, in the direction in which the first contact portion 351 contacts the door check 11. Rush. As a result, the urging unit 38 makes the vehicle travel by bringing the opening adjustment block 35 into contact with the door check 11 when the opening adjustment block 35 is disposed at a position that restricts the opening of the door D. The backlash of the opening adjustment block 35 due to vibration at the time can be suppressed. It should be noted that the biasing portion 38 has an elastic modulus such that when the lever 42 is in the fully open operation position, the opening adjustment block 35 is not disposed at a position where the opening adjustment block 35 contacts the door check 11 by the biasing of the biasing portion 38. Composed.

  Unlike the operation device 20, the operation device 40 includes a lever 42 that is not connected to the base and is connected to the rotation shaft 111 of the opening adjustment block 35 so as to be rotatable. The lever 42 includes a connection portion 421 connected to the biasing portion 37, a knob 423, a hole portion 424 through which the rotation shaft 111 is passed, and an engagement portion 425 that engages with the engagement portion 356 of the opening adjustment block 35. Is provided. The lever 42 can be rotated about the rotation shaft 111 by passing the rotation shaft 111 through the hole 424, and is connected to the opening adjustment block 15 via the rotation shaft 111 so as to be rotatable. ing.

  The engaging portion 425 is composed of a rod-shaped member, and the lever 42 and the opening adjustment block 35 are engaged by engaging with the engaging portion 356 of the opening adjustment block 35 formed by a groove and a protrusion. Connecting. Accordingly, the user can integrally rotate the lever 42 and the opening adjustment block 35 around the rotation shaft 111. Here, when the opening adjustment block 35 and the lever 42 are moved away from each other, if an external force of a predetermined value or more is applied to the engaging portion 356 and the engaging portion 425, the engaging portion 356 and the engaging portion 356 are engaged. The engagement of the joint portion 425 is released. As a result, the opening adjustment block 35 and the lever 42 can be separated and rotated.

  Next, with reference to FIG. 6A thru | or D, operation | movement of the opening degree adjustment block 35, the lever 42, and the urging | biasing part 37 in the door check mechanism 2 by a present Example is demonstrated. FIG. 6A shows the opening adjustment block 35, the urging unit 37, and the lever 42 when the opening adjustment block 35 is disposed at a position where the opening of the door D is limited. FIG. 6B shows the opening adjustment block 35, the urging unit 37, and the lever 42 when the opening adjustment block 35 is disposed at a position where the opening of the door D is set to the fully open position. 6C, the opening adjustment block 35 is disposed at a position that restricts the opening of the door D, and the opening adjustment block 35, the urging unit 37, and the lever 42 when the door D is opened to the opening that is restricted. Indicates. 6D shows an opening when the opening adjustment block 35 is arranged at a position that restricts the opening of the door D, and the lever 42 is moved to the fully opened operation position when the door D is opened to the opening that restricts the opening. The degree adjustment block 35, the biasing part 37, and the lever 42 are shown. In FIGS. 6A to 6D, for simplification of description, the bearing portion of the rotation shaft 111 provided on the bracket 14, the door D, and the door check 11 is omitted.

  When the opening adjustment block 35 is disposed at a position that restricts the opening of the door D, the opening adjustment block 35 is provided between the door check 11 and the check stopper portion 13 as shown in FIG. 6A. Be placed. The lever 42 can be held at the restricting operation position by using an arbitrary holding member (not shown). When the opening adjustment block 35 is arranged at a position that restricts the opening of the door D, the check stopper portion 13 reaches the position where the check stopper portion 13 contacts the second contact portion 352 of the opening adjustment block 35. It can move in 12 extending directions. Therefore, the user can freely open the door D to the opening degree limited by the opening degree adjustment block 35.

  Next, the user rotates the lever 42 to the fully open operation position as shown in FIG. 6B. In this case, the urging portion 37 moves according to the rotation of the lever 42, and the opening adjustment block 35 is rotated upward about the rotation shaft 111. When the engagement portions 356 and 425 are engaged, the opening adjustment block 35 is connected to the lever 42 by the connection of the opening adjustment block 35 and the lever 42 by the engagement of the engagement portions 356 and 425. It can also be rotated based on the movement. The lever 42 can be held at the fully open operation position using an arbitrary holding member (not shown). When the opening adjustment block 35 is disposed at a position where the opening degree of the door D is set to the fully opened opening degree, the check stopper portion 13 does not contact the opening adjustment block 35 and the check link 12 extends. Can move in the direction. Therefore, the user can open the door D freely to the fully open position. FIG. 6B shows a state where the engaging portion 356 and the engaging portion 425 are engaged. However, even when the opening adjustment block 35 is rotated according to the movement of the lever 42 to the fully open operation position while the engagement portions 356 and 425 are disengaged, the opening adjustment block 35 is not included in the check stopper portion 13. It can be rotated to a position where it does not abut.

  On the other hand, when the opening adjustment block 35 is arranged at a position where the opening degree of the door D is restricted, when the door D is opened to the opening degree where the opening degree is restricted, as shown in FIG. 13 moves to a position where it contacts the second contact portion 352 of the opening adjustment block 35. In this case, the opening adjustment block 35 is sandwiched between the door check 11 and the check stopper portion 13, thereby restricting the movement of the check link 12 toward the one end attached to the vehicle body. Further, since the check stopper portion 13 is in contact with the second contact portion 352 and the door check 11 and the check stopper portion 13 sandwich the opening adjustment block 35, the rotation of the opening adjustment block 35 is restricted. .

  In this case, since the rotation of the opening adjustment block 35 is restricted even if the user tries to rotate the lever 42 to the fully open operation position, the opening adjustment block 35 rotates as the lever 42 rotates. I can't move. Therefore, when the engaging portion 356 and the engaging portion 425 are engaged, the engagement of the engaging portion 356 and the engaging portion 425 is released based on the operation of the lever 42 by the user, and the opening degree is adjusted. The block 35 and the lever 42 can be separated and rotated. Here, when the lever 42 is rotated to the fully open operation position, the distance between the lever 42 and the opening adjustment block 35 at the position where the opening degree of the door D is limited, in particular, the knob 423 (operation part) and the opening degree. The distance of the adjustment block 35 becomes long.

  Here, in the door check mechanism 2 according to the present embodiment, the opening adjustment block 35 and the lever 42 are connected using the biasing portion 37. The urging portion 37 is configured to be extendable in the extending direction, and when the distance between the opening adjustment block 35 and the lever 42 increases as the lever 42 moves, the opening adjustment block 35 and the lever 42 are Stretch between. Therefore, even when the distance between the opening adjustment block 35 and the lever 42 becomes longer as the lever 42 moves, the opening adjustment is performed by extending (deforming) the urging portion 37 as shown in FIG. 6D. The lever 42 can move while maintaining the connection between the block 35 and the lever 42. Thus, even when the opening adjustment block 35 is sandwiched between the door check 11 and the check stopper portion 13 and the rotation is restricted, the user can easily push the lever 42 connected to the opening adjustment block 35. Can be operated and moved. Therefore, it is possible to prevent the user from applying an excessive load to the operating device 40 and to suppress damage to the operating device 40 and the connection member.

  Further, when the lever 42 moves in a direction away from the opening adjustment block 35 while extending (deforming) the urging portion 37 and then pivots in the direction in which the door D is closed, the check link 12 moves toward the check stopper portion 13. The check stopper portion 13 moves away from the second contact portion 352. Therefore, the holding of the opening adjustment block 35 by the door check 11 and the check stopper portion 13 is released, and the opening adjustment block 35 can be rotated. Here, the extending urging portion 37 is in a state where an external force is applied in the extending direction in the extending direction along with the movement of the lever 42 and the external force is stored. Therefore, the extending urging unit 37 applies an external force in a direction approaching the lever 42 to the opening adjustment block 35 according to the elastic force based on the stored external force, and urges the opening adjustment block 35 in the direction. . Therefore, the opening adjustment block 35 can be rotated in a direction approaching the lever 42 by the biasing based on the extension of the biasing portion 37. In particular, when the lever 42 has moved to the fully open operation position, the opening adjustment block 35 can move to a position that does not limit the opening of the door D. Thereafter, the opening adjustment block 35 rotates again with the rotation of the lever 42 via the biasing portion 37.

  As described above, in the door check mechanism 2 according to this embodiment, the lever 42 is rotatably connected to the opening adjustment block 35. In the door check mechanism 2, when the first contact portion 351 of the opening adjustment block 35 contacts the door check 11 and the check stopper portion 13 contacts the second contact portion 352, the lever 42 is a biasing portion. It moves while extending (deforming) 37. Thus, even when the opening adjustment block 35 is sandwiched between the door check 11 and the check stopper portion 13 and the rotation is restricted, the user can easily push the lever 42 connected to the opening adjustment block 35. Can be operated and moved. Therefore, it is possible to prevent the user from applying an excessive load to the operating device 40 and to suppress damage to the operating device 40 and the connection member.

  In the door check mechanism 2, the opening adjustment block 35 and the lever 42 are provided with engaging portions 356 and 425 that engage with each other, respectively. Thereby, when the engaging parts 356 and 425 are engaged, the opening adjustment block 35 and the lever 42 are connected, and the opening adjustment block 35 and the lever 42 can be integrally rotated. Further, when the rotation of the opening adjustment block 35 is restricted by the door check 11 and the check stopper portion 13 and the lever 42 rotates while the urging portion 37 is extended (deformed), the engagement portions 356 and 426 The engagement is released. As a result, when the urging portion 37 extends, the opening adjustment block 35 and the lever 42 can be separated and rotated, so that even if the rotation of the opening adjustment block 35 is restricted. The lever 42 can be rotated. The engaging portions 356 and 425 are in the disengaged state, and when the user moves the lever 42 to the restricting operation position, the opening adjusting block 35 that abuts the door check 11 and restricts the rotation. It can be configured to engage with the lever 42 approaching. Further, the engaging portions 356 and 425 are engaged with each other by the rotation of the opening adjustment block 35 when the urging portion 37 that has been extended urges the opening adjustment block 35 toward the lever 42. It can also be configured. Even when the engaging parts 356 and 426 are not engaged, the biasing part 37 connects the opening adjustment block 35 and the lever 42, so that the opening adjustment block 35 is used to rotate the lever 42. Can be rotated based on.

  Further, the engaging portions 356 and 426 can have any shape as long as they are engaged with each other and are disengaged when the lever 42 moves away from the opening adjustment block 35. . For example, the engagement portion of the opening adjustment block 35 may have a groove shape, and the engagement portion of the lever 42 may have a convex shape corresponding to the engagement portion of the opening adjustment block 35.

  The urging unit 37 can be connected to any part of the opening adjustment block 35 and the lever 42, respectively. For example, the biasing portion 37 and the end portion on the side where the knob 423 is provided may be connected. Further, the urging portion 37 can be connected to the opening adjustment block 35 and the lever 42 via an arbitrary connecting member such as a wire or a cable rod-shaped member (rod).

  In the door check mechanism 2 according to the present embodiment, the lever 42 is pivotally connected to the pivot shaft 111 of the opening adjustment block 35 and is pivotally connected to the opening adjustment block 35. The structure which connects 42 with respect to the opening degree adjustment block 35 is not restricted to this. For example, the lever 42 may be pivotably connected to another pivot shaft provided in the opening adjustment block 35. Further, the opening adjustment block 35 may be pivotably connected to a pivot shaft provided on the lever 42.

  Further, the deformation of the urging portion 37 is not limited to expansion. The urging unit 37 urges the opening adjustment block 35 and the lever 42 toward each other, and when the movement of the opening adjustment block 35 is restricted, the urging unit 37 is deformed to deform the opening adjustment block 35 and the lever 42. It is only necessary to allow the movement of the lever 42 while maintaining the connection. Therefore, the deformation of the urging portion 37 is not limited to expansion / contraction, and may be a deformation in an arbitrary form, for example, a bending deformation or a twisting deformation.

  In the door check mechanism 2 according to the second embodiment, the lever 42 and the opening adjustment block 35 are connected by an urging portion 37 configured to be extendable, and are urged toward each other. However, the configuration of the urging unit that connects the lever and the opening adjustment block and urges the lever in a direction approaching each other is not limited thereto. In the door check mechanism according to the present embodiment, an urging portion that is connected to the lever and the opening adjustment block and is deformable by the rotation of the lever with respect to the opening adjustment block is provided. Since the door check mechanism according to the present embodiment has the same configuration as the door check mechanism 2 according to the second embodiment, the difference will be mainly described with reference to FIGS. 7A and 7B.

  7A and 7B show the operations of the opening adjustment block 55, the urging unit 57, and the lever 62 in the door check mechanism according to this embodiment. 7A, the opening adjustment block 55 is disposed at a position that restricts the opening of the door D, and the opening adjustment block 55, the urging portion 57, and the lever 62 when the door D is opened to the opening that is restricted. Indicates. In FIG. 7B, the opening adjustment block 55 is arranged at a position that restricts the opening degree of the door D, and when the door D is opened to the opening degree that is restricted, the lever 62 is moved to the fully opened operation position. The degree adjustment block 55, the urging portion 57, and the lever 62 are shown.

  As shown in FIG. 7A, the door check mechanism according to the present embodiment has the same configuration as the door check mechanism 2 according to the second embodiment, but a biasing portion 57 is provided instead of the biasing portion 37. The door check mechanism according to this embodiment is provided with an opening adjustment block 55 and a lever 62. The lever 62 is connected to the opening adjustment block 55 so as to be rotatable about the rotation shaft 111. The lever 62 and the opening adjustment block 55 are connected to each other by an urging portion 57 provided coaxially with the rotation shaft 111 and are urged toward each other.

  The urging portion 57 can be composed of an elastic member such as a torsion coil spring or a leaf spring, and is configured as a torsion coil spring in this embodiment. One end of the urging portion 57 is connected to the opening adjustment block 55, and the other end is connected to the lever 62. Thereby, the urging | biasing part 57 can urge the opening degree adjustment block 55 and the lever 62 in the direction which mutually approaches. Further, the urging portion 57 is deformable so that one end connected to the opening adjustment block 55 and the other end connected to the lever 62 move away from each other, and the opening adjustment block The lever 62 can be deformed by turning the lever 62 with respect to 55.

  Therefore, when the opening adjustment block 55 shown in FIG. 7A is sandwiched between the door check 11 and the check stopper portion 13 and the rotation of the opening adjustment block 55 is restricted, the lever 62 is moved to the opening adjustment block. When rotating in a direction away from 55, the urging portion 57 is deformed. FIG. 7B shows the opening adjustment block 55, the urging portion 57, and the lever 62 at this time. The urging unit 57 connects the lever 62 and the opening adjustment block 55 and urges them in a direction approaching each other while being deformed based on the rotation of the lever 62. Here, the urging portion 57 that is deformed has an external force in a direction in which the other end connected to the lever 62 moves away from the one end connected to the opening adjustment block 55 as the lever 62 moves. Is applied and the external force is stored. Thereafter, when the door D is rotated in the closing direction, the holding of the opening adjustment block 55 by the door check 11 and the check stopper portion 13 is released. Therefore, the deforming biasing portion 57 applies an external force in a direction approaching the lever 62 to the opening adjustment block 55 according to the elastic force based on the stored external force, and biases the opening adjustment block 55 in the direction. . The opening adjustment block 55 can be rotated in a direction approaching the lever 62 by biasing based on deformation of the biasing portion 57. Thereafter, the opening adjustment block 55 can be rotated with the movement of the lever 62 again.

  Thus, in the door check mechanism according to the present embodiment, the first contact portion 551 of the opening adjustment block 55 contacts the door check 11 and the check stopper portion 13 contacts the second contact portion 552. Sometimes, the lever 62 rotates while deforming the urging portion 57. Thereby, even when the opening adjustment block 55 is sandwiched between the door check 11 and the check stopper portion 13 and the rotation is restricted, the user can easily push the lever 62 connected to the opening adjustment block 55. Can be operated and moved. Therefore, it is possible to prevent the user from applying an excessive load to the operating device, and to suppress damage to the operating device, the connection member, and the like.

  In the door check mechanism according to this embodiment, since the torsion coil spring is used as the urging portion 57, the urging portion 57 is twisted and deformed by the movement of the lever 62. On the other hand, when the urging portion 57 is composed of an elastic member such as a leaf spring, the urging portion 57 is bent and deformed by the movement of the lever 62. It is not necessary to provide the urging portion 57 coaxially with the rotation shaft 111. The urging unit 57 urges the opening adjustment block 55 and the lever 62 in a direction approaching each other, and can be deformed by turning the lever 62 with respect to the opening adjustment block 55. What is necessary is just to be connected to the lever 62. FIG.

  In the door check mechanism according to the present embodiment, the lever 62 is pivotally connected to the pivot shaft 111 of the opening adjustment block 55 and is pivotally connected to the opening adjustment block 55. The structure which connects the lever 62 with respect to the opening degree adjustment block 55 is not restricted to this. For example, the lever 62 may be pivotably connected to another pivot shaft provided in the opening adjustment block 55. Further, the opening adjustment block 55 may be pivotably connected to a pivot shaft provided on the lever 62.
