Abstract

A door opening degree adjustment device includes a check link having a stopper portion, a guide member having a guide hole, and an adjustment member. The adjustment member includes a plurality of stages of step portions and a guide projection that is inserted in the guide hole movably in the extending direction of the guide hole. The adjustment member causes the stopper portion to contact the step portions of any one of the stages, thereby restricting an opening operation caused by pivoting of the door in one direction. The guide projection is arranged on an extended line that connects the stopper portion to one of the stages of the step portions that contacts the stopper portion in the direction of the movement of the check link.

First claim

The invention claimed is:

1. A door opening degree adjustment device comprising:
a check link configured to be pivotally coupled to a body of a vehicle and to be extended into a door pivotally coupled to the body, wherein the check link has a stopper portion in a distal end;
a guide member configured to be fixed in the door, wherein the guide member includes a guide hole extending in a direction different from a direction of movement of the check link caused by pivoting of the door; and
an adjustment member, wherein
the adjustment member includes
a plurality of stages of step portions, and
a guide pin that is inserted in the guide hole movably in the extending direction of the guide hole,

the adjustment member causes the stopper portion to contact the step portions of any one of the stages, thereby restricting an opening operation caused by pivoting of the door in one direction, and
the guide pin is arranged on an extended line that connects the stopper portion to one of the stages of the step portions that contacts the stopper portion in the direction of the movement of the check link.

2. The door opening degree adjustment device according to claim 1 , wherein
the adjustment member is arranged movably in a direction different from the direction of the movement of the check link caused by pivoting of the door,
the stopper portion has a plurality of stages of check-side step portions in the direction of the movement of the check link,
the adjustment member has a plurality of stages of adjustment-side step portions, wherein the number of stages of the adjustment-side step portions is greater than the number of stages of the check-side step portions, and
the adjustment member causes the stages of the check-side step portions to contact the stages of the adjustment-side step portions in an engaged state, thereby restricting the opening operation caused by pivoting of the door in the one direction.

3. The door opening degree adjustment device according to claim 1 , wherein
movement of the adjustment member in a direction different from the direction of the movement of the check link caused by pivoting of the door is guided in a predetermined movement range by the guide member, and
the door opening degree adjustment device comprises:
an urging member that urges the adjustment member such that the adjustment member moves toward one of ends of the predetermined movement range, and
a cable coupled to the adjustment member, wherein, against urging force of the urging member, the cable holds the adjustment member at a position corresponding to a manipulation amount, and
the adjustment member has an escape portion that releases the stopper portion when located at the end.

4. The door opening degree adjustment device according to claim 1 , wherein
movement of the adjustment member in a direction different from the direction of the movement of the check link caused by pivoting of the door is guided in a predetermined movement range by the guide member, and
the door opening degree adjustment device comprises:
an urging member that urges the adjustment member such that the adjustment member moves toward a first end, which is one of ends of the predetermined movement range; and
a cable coupled to the adjustment member, wherein, against urging force of the urging member, the cable holds the adjustment member at a position corresponding to a manipulation amount, and

the adjustment member has an escape portion that releases the stopper portion when located at a second end, which is the other end of the predetermined movement range.

5. The door opening degree adjustment device according to claim 1 , wherein the guide projection has a flat section at a position at which the guide pin slidably contacts the guide hole.

6. The door opening degree adjustment device according to claim 1 , wherein the guide member has an attaching wall that is held in contact with and attached to a wall portion of the door through which the check link is inserted.

7. The door opening degree adjustment device according to claim 6 , comprising a door check that is held in contact with and attached to the attaching wall, wherein
the check link is inserted through the door check, and
the door check is caused to contact the stopper portion in a state released from the adjustment member, thereby restricting the opening operation caused by pivoting of the door in the one direction at a fully open position.

8. The door opening degree adjustment device according to claim 1 , wherein
the adjustment member has a pair of adjustment walls,
the adjustment walls have the stages of the step portions and the guide pin such that the check link is allowed to be held between the adjustment walls in a parallel-arrangement direction that is different from the direction of the movement of the check link and the extending direction of the guide hole,
the guide member has a pair of support walls having the guide hole such that the adjustment member is held between the support walls in the parallel-arrangement direction, and
the check link has a pair of the stopper portions such that each of the stopper portions is allowed to contact any one of the stages of the step portions of the adjustment walls.

9. A door opening degree adjustment device comprising:
a check link configured to be pivotally coupled to a body of a vehicle and to be extended into a door pivotally coupled to the body, wherein the check link has a stopper portion in a distal end;
a guide member configured to be fixed in the door;
an adjustment member having a step portion, wherein
movement of the adjustment member in a predetermined movement range in a direction different from a direction of movement of the check link caused by pivoting of the door is guided by the guide member, and
the adjustment member restricts an opening operation caused by pivoting of the door in one direction by causing the stopper portion to contact the step portion;

an urging member that urges the adjustment member such that the adjustment member moves toward one of ends of the predetermined movement range; and
a cable coupled to the adjustment member, wherein, against urging force of the urging member, the cable holds the adjustment member at a position corresponding to a manipulation amount, wherein
the adjustment member has an escape portion that releases the stopper portion when located at the end,
one of a guide hole extending in the direction of movement of the adjustment member and a guide pin movably inserted in the guide hole is arranged in the guide member,
the other one of the guide hole and the guide pin is arranged in the adjustment member, and
the end is determined by locating the guide pin at one of ends of the guide hole.

10. A door opening degree adjustment device comprising:
a check link configured to be pivotally coupled to a body of a vehicle and to be extended into a door pivotally coupled to the body, the check link having a stopper portion in a distal end;
a guide member configured to be fixed in the door;
an adjustment member including a step portion, wherein
movement of the adjustment member in a predetermined movement range in a direction different from a direction of movement of the check link caused by pivoting of the door is guided by the guide member, and
the adjustment member restricts an opening operation caused by pivoting of the door in one direction by causing the stopper portion to contact the step portion;

an urging member that urges the adjustment member such that the adjustment member moves toward a first end, which is one of ends of the predetermined movement range; and
a cable coupled to the adjustment member, wherein, against urging force
