Abstract

The invention discloses a rotary positioning mechanism, an armrest frame with a rotatable armrest seat, and a chair. The rotary positioning mechanism is suitable for being mounted on a chair armrest, and the chair armrest is provided with a supporting rod and the armrest seat capable of rotating relative to the supporting rod. The rotary positioning mechanism comprises a fixing unit and a rotating unit. The fixing unit comprises a fixing plate, an elastic ring piece and a joint block. The fixing plate is provided with two arc grooves. The elastic ring sheet is arranged between the arc grooves and is provided with a plurality of arc concave parts. A plurality of joint concave surfaces are formed on the joint block. The rotating unit rotates along with the armrest seat and comprises a linkage plate and a pushing piece. The linkage plate is provided with two rotating columns extending to the arc grooves respectively, and each rotating column is used for being in friction joint with one arc concave part. The pushing piece can be jointed with one of the joint concave surfaces in an elastic pushing manner. The armrest frame with the rotatable armrest seat and the chair comprise the rotary positioning mechanism.

Description

technical field [0001] The invention relates to a chair, in particular to a rotating positioning mechanism, a rotatable armrest frame and a chair. Background technique [0002] The swivel armchair can be rotated horizontally to adjust the position of its armrests according to body movements, which helps maintain correct body posture, reduces hand pressure, is more ergonomic, and can improve the comfort of sitting for a long time. [0003] refer to figure 1 and figure 2 , a multifunctional chair armrest assembly, taking US Patent Application Publication No. 20080073965A1 as an example, includes a rotating member 12 installed inside the armrest 11 and rotating with the armrest 11, a rotating member 12 And the holder 13 is fixedly connected with the armrest support (not shown). The rotating member 12 has a chamber 120 through the top and bottom for the holder 13 to be placed, and a plurality of tooth portions 121 located on two opposite sides and communicating with the cham...
