Description

  The present invention relates to a pivot mounting structure for a member that allows a rotating member to be rotatably attached to a structure.

  Conventionally, as a pivoting structure of members, for example, in a cabinet used in an office space such as an office, a front opening is arranged with a left door, an intermediate door, and a right door superimposed on the front and back, and a pair of left and right is reversed. One end of each link bar in the V-shaped link bar is connected to the left and right doors, and the other end of the link bar is an interlocking member such as a roller or a slider that can be moved up and down on a guide rail provided on the intermediate door along the vertical direction. In addition, each of them is coaxially pivoted so as to synchronize to improve the operability at the time of opening and closing the door and to prevent the generation of abnormal noise (Patent Document 1, Patent Document 1). 2).

However, in the one described in Patent Document 1, when one end of the link bar is pivotally attached to the door, a brush hole-shaped mounting hole including a large diameter hole and a small diameter hole is formed in the bearing portion of the door. At the same time, a pivot shaft composed of a large-diameter shaft portion and a small-diameter shaft portion is formed in the pivot attachment portion of the link bar, and the large-diameter shaft portion of the pivot shaft is inserted into the large-diameter hole of the mounting hole, and the small-diameter shaft portion is reduced in diameter. By being guided into the hole, it can be easily attached and detached. For this reason, when a load is applied to the link bar, the pivot shaft swings in the vertical direction, and not only the rotation of the link bar cannot be stably maintained but also the pivot shaft may be detached from the mounting hole.
Further, in the device described in Patent Document 2, a retaining piece is provided in the mounting hole so as to prevent the pivot from being detached. However, when a load is applied to the link bar, the pivot is swung in the vertical direction. The link bar cannot be stably rotated.

Claims (6)

A pivot attachment structure for a member attached so that the pivot member can be pivotally mounted by inserting a pivot formed in the pivot portion of the pivot member into an attachment hole formed in the attachment surface of the structure. In
The mounting hole includes an insertion hole, a circular fixing hole that is spaced downward from the insertion hole and has a smaller diameter than the insertion hole, and is narrower than the diameter of the fixing hole, and the fixing hole and the insertion hole are It is formed by a communicating part that communicates,
The pivot shaft has a base shaft portion having a diameter smaller than the width of the communication portion of the mounting hole, and a step formed at a tip portion of the base shaft portion, and has a large diameter shaft portion having a diameter smaller than the insertion hole and larger than the fixed hole. The intermediate shaft portion is formed with a step between the large diameter shaft portion and the base shaft portion, and is smaller in diameter than the fixed hole and larger in diameter than the width of the communication portion,
The pivot shaft base shaft portion inserted from the mounting hole insertion hole is guided to the fixing hole through the communication portion, and the pivot shaft intermediate shaft portion is fitted to the fixing hole, and the mounting surface of the structure and the rotating member A pivoting structure for a member, wherein a fixing member is positioned between the pivot forming surface and the pivoting member can be prevented from moving in the pivotal direction.   2. The fixing member according to claim 1, wherein the fixing member includes a base portion and an insertion holding portion that is provided on the base portion and is inserted into the base shaft portion of the pivot of the rotating member and held in a pinched state. The pivot structure of the member.   The pivot of the member according to claim 1 or 2, wherein an inclined shaft portion whose diameter is increased from the base shaft portion toward the intermediate shaft portion is formed between the base shaft portion and the intermediate shaft portion of the pivot shaft in the rotating member. Wearing structure.   4. The member pivoting structure according to claim 3, wherein the inner peripheral surface of the fitting holding portion in the fixing member is an inclined surface that matches the outer peripheral surface of the inclined shaft portion. The fixing member includes a substrate, a horizontal piece that is bent in the horizontal direction from the upper edge of the substrate in the horizontal direction by the thickness of the rotating member, and a hanging piece that is suspended from the front edge of the horizontal piece. Part, a notch formed in the hanging piece part, and a fitting holding part that is fitted in the base shaft part of the pivot and is held in a clamped state, and is bent in a horizontal direction from the lower end edge of the substrate toward the front. Formed with locking pieces,
The hanging piece is inserted from above to below between the mounting surface of the structure and the pivot forming surface of the rotating member, and
2. The pivot mounting structure for a member according to claim 1, wherein the locking piece can be locked to a lower surface portion of the rotating member when the insertion holding portion is inserted into the base shaft portion of the pivot. The fixing member was raised in the vertical direction from the substrate, a horizontal piece bent in the horizontal direction by approximately the thickness of the structure toward the front from the lower edge of the substrate, and the front edge of the horizontal piece. A rising piece, a check claw-like locking protrusion protruding from the rear surface of the rising piece, a notch formed in the substrate, and fitted into the base shaft of the pivot to be held in a clamped state. It is formed with the insertion holding part,
The substrate is inserted from below to above between the mounting surface of the structure and the pivot forming surface of the rotating member, and
When the insertion holding portion is inserted into the base shaft portion of the pivot, the rising piece can be positioned so as to sandwich the attachment surface of the structure, and the locking protrusion can be locked in the locking hole formed in the structure. 2. The pivot mounting structure for a member according to claim 1, wherein the member is pivoted.
