[0003]

In the case of automobile doors, building doors, and the like, it is sometimes required to change the check position depending on the user's body shape and preference or the situation of the place where the door is opened and closed. However, the conventional check device as described above includes a link member (102) for determining a check position.
The position of the check section (104) is fixed and the check position cannot be changed.Depending on the usage conditions, the opening is too wide and the end of the door hits an adjacent object, or the opening is too narrow to use. There are problems such as inconvenience of getting on and off of a person.

[0004] The present invention has been made in view of the above-mentioned problems of the prior art, and provides an improved door check device capable of changing a door check position in accordance with a use situation or the like. The purpose is.

[0005]

In order to achieve the above object, the present invention provides a door opening / closing operation in which a check member squeezes and grips a link member in conjunction with the door opening / closing operation. In the door check device, the check member forms a part of the sliding portion of the link member that slides, and the check member is engaged to apply a large resistance force to the door. 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 practice, the intermediate portion of the movable piece is pivotally mounted on 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 moved in the longitudinal direction of the link member from the axis of the movable piece. It is preferable that the position of the check unit can be changed by inverting the movable piece by providing it at a remote position.

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

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

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

[0010] Further, the fastening means is a set screw, and the movable piece is provided with an elongated hole for adjusting the position, which is oriented in the longitudinal direction of the link member, and through which the set screw is slidably inserted in the longitudinal direction. It may be perforated.

[0011]

When the movable piece is moved such that the position of the check portion is displaced in the longitudinal direction of the link member, the check position at which a large resistance is applied to the opening and closing operation of the door changes.
