A roller (not shown) provided in the case (103) of 1) is pressed by the urging force of an elastic member (not shown) also provided in the case (103), and the length of the link member (102) is increased. Recessed check part (104) provided on the upper and lower surfaces of the center of the direction
By engaging with the door, a large resistance force is applied to the opening / closing operation of the door, and the door can be held in the half-open position.

[0003]

In the case of doors of automobiles, doors of buildings, etc., it may be required to change the check position depending on the body shape and preferences of the user or the situation of the place where the door is opened and closed. However, in the conventional check device as described above, the link member (102) that determines the check position is used.
The position of the check part (104) is fixed, the check position cannot be changed, and depending on the usage conditions, the opening amount is too wide and the edge of the door hits an adjacent object, or the opening amount is too narrow. There is a problem that it is inconvenient for people to get on and off.

In view of the above-mentioned problems of the prior art, the present invention provides an improved door check device that can change the door check position according to usage conditions and the like. Has an aim.

[0005]

In order to achieve the above object, the present invention has an opening / closing operation of a door by interlocking with an opening / closing operation of a door, and a check member slides by gripping a link member. In a door check device for applying a resistance force to a door, a large resistance force is applied to a door by forming a part of a sliding portion of a link member on which a check member slides and engaging the check member. The movable piece having the recessed check portion is mounted on the link member such that the position of the check portion is displaceable in the longitudinal direction of the link member.

In carrying out the invention, the intermediate portion of the movable piece is pivotally attached to the link member so as to be reversible with an axis orthogonal to the longitudinal direction of the link member, and the check portion is arranged in the longitudinal direction of the link member from the axis of the movable piece. It is preferable that the check pieces can be changed in position by reversing the movable piece by disposing the check pieces in a distant position.

In this case, the check portion is provided on a plane parallel to the plane including the rotation center axis of the movable piece and the longitudinal axis of the link member, or on the plane orthogonal to the rotation center axis of the movable piece. Is good.

Further, in practice, the movable piece may be slidably mounted in the longitudinal direction of the link member, and fastening means for fastening the movable piece to the link member at an arbitrary position may be provided.

In this case, the fastening means is a set screw,
It is preferable that a plurality of adjustment holes for position adjustment through which the set screw is selectively inserted are formed in the movable piece.

Further, the fastening means is a set screw, and the movable piece is provided with an elongated hole-shaped adjusting hole for adjusting the position, which faces the longitudinal direction of the link member, and through which the set screw is slidably inserted in the longitudinal direction. You may pierce.

[0011]

When the movable piece is moved so that the position of the check portion is displaced in the longitudinal direction of the link member, the check position where a large resistance force is applied to the opening / closing operation of the door is changed.
