    • Mounts are provided on the inside surface of the left and the right sides of a seat cover on the underside of a chair, and positioning pins with heads and fastening members are provided on the upper surfaces of the bases of armrests. Each mount includes keyholed-shaped positioning holes respectively having holes for insertion of the heads of the positioning pins and slits of a width suitable for slidably receiving the rods of the positioning pins. Each mount also includes a support hole for the fastening member to be engaged in. When the positioning pins are located at the rear ends of the slits of the positioning holes, the armrest is fixed to the mount through the support hole by the fastening member. Thus the armrests are removably assembled with the chair body. The seat cover has upper and lower protrusions which contact the mount and the base of the armrest, respectively. The mount is bent so that its outboard and inboard portions are inclined relative to each other.
    • 在椅子下侧的座椅盖的左侧和右侧的内表面上设有安装件,并且在扶手的底座的上表面上设置有具有头部和紧固构件的定位销。 每个安装件包括分别具有用于插入定位销的头部的孔和适于可滑动地容纳定位销的杆的宽度的狭缝的锁定孔定位孔。 每个安装件还包括一个用于接合的紧固件的支撑孔。当定位销位于定位孔的狭缝的后端时,扶手通过紧固件通过支撑孔固定到支架上。 因此扶手可拆卸地组装在椅子主体上。 座椅盖具有分别与扶手和扶手的底座相接触的上下突起。 该安装件弯曲,使得其外侧和内侧部分相对于彼此倾斜。

    • The present device relates to a chair in which a base member is fitted onto an upper portion of a leg comprising a plurality of castors in contact with a floor together with support members for these castors, and a seat portion and a back rest are provided on an upper portion of a support plate that is capable of reclining with respect to the base member. This chair is also provided with a cam-shaped link capable of rotating about the periphery of a pin provided in the base member, an upper portion of the link protrudes towards the support plate side, and a corresponding elastic member that is compressed by the rotation of the link is provided in a bottom portion of the base member. A shaft portion in contact with the link, and which causes the link to change profile in response to the reclining action, is provided within the support plate. This configuration provides a chair that is inexpensive and can naturally adopt either a serious working position or a relaxed reclining position.
