Embodiment Construction

[0067] The seat device of the present invention may be any one of office chairs, work chairs, stools or standing aids. In this embodiment, the seat stool is taken as an example for description. The stool 1 stands on the ground 2 by its base. The base is designed as a star base 3 . The star base 3 includes a central base 4 (also called "hub") and five extension arms 5 mounted on the central base. The extending arms are evenly distributed along the center base. A roller 6 is fixed at the free end of the extension arm 5 . In the center of the center seat 4 is an accommodating sleeve 7 for the chair post 8, and the height of the chair post 8 can be adjusted by means of a gas spring (not shown in the figure).

[0068] The top of the chair post 8 is a supporting structure for placing the seat surface 9 . In the simple example shown here, the support structure includes a base support 10 and a seat support 12 . The base support 10 is placed on the chair column 8 together with a ...

Abstract

The invention discloses a seat device and a star-shaped base thereof. The seat device and the star-shaped base thereof can be particularly used for office seats, working seats, stools or standing auxiliary devices. The seat device is characterized in that the seat face can rotate or swing, and meanwhile parts installed at the upper ends of seat columns do not need to be changed, especially a supporting structure, a seat support for containing the seat face and the seat face do not need to be changed; rotation or swing of the seat face can be realized by modifying parts, mounted at the lower ends of the seat columns, of the seat device, namely mounting the movable star-shaped base. The star-shaped base is characterized in that at least one of extending arms installed on a hub is hinged to the hub and can rotate relative to the hub.

Description

technical field [0001] The invention relates to a seat device and its star-shaped base, in particular a base for office chairs, work chairs, stools or standing aids. Background technique [0002] Today, star bases are the standard solution for pedestals for seating installations, especially office chairs, task chairs and stools. Usually, it comes with a chair post that can be adjusted in height. There is a supporting structure on the chair post, which is used to place the chair surface. Supporting structures include, for example: foundation supports, seat supports and, if required, seat back supports. Star bases are often applied on swivel chairs or stools, or on seats. The seat surface of these devices can be rotated about the longitudinal axis of the chair post. [0003] Regardless of the existing removable and adjustable seats, these days, the so-called "movable chairs" are heavily hyped from an ergonomic point of view. The posture of such a seating device, such as i...
