Abstract
A foldable chair frame and a foldable chair are provided. The foldable chair frame includes a base, having three or more opening grooves; and three or more joint structures, each including a first rotating member and a second rotating member that are coaxially pin-jointed in the opening groove. A stopper that limits a relative rotation angle between the second rotating member and the first rotating member is disposed on the first rotating member. A first abutting part that limits a relative rotation angle between the first rotating member and the base is disposed on the first rotating member; and/or a second abutting part that limits relative rotation angle between the second rotating member and the base is disposed on the second rotating member.
Claims16
A foldable chair frame, comprising:
- a base, having three or more opening grooves;
- and
- three or more joint structures, each comprising a first rotating member and a second rotating member that are coaxially pin-jointed in a corresponding opening groove, wherein
- a stopper that limits a relative rotation angle between the second rotating member and the first rotating member is disposed on the first rotating member;
- and
- a first abutting part that limits a relative rotation angle between the first rotating member and the base is disposed on the first rotating member;
- and/or
- a second abutting part that limits relative rotation angle between the second rotating member and the base is disposed on the second rotating member;
- wherein a plurality of arc-shaped grooves are disposed on one of the first rotating member and the second rotating member, limiting posts that fit with the arc-shaped grooves through sliding and limiting are disposed on the other of the first rotating member and the second rotating member, and a center of the arc-shaped groove is located on a pivot of the first rotating member.
A foldable chair frame, comprising:
- a base, having three or more opening grooves;
- and
- three or more joint structures, each comprising a first rotating member and a second rotating member that are coaxially pin-jointed in a corresponding opening groove, wherein
- a stopper that limits a relative rotation angle between the second rotating member and the first rotating member is disposed on the first rotating member;
- and
- a first abutting part that limits a relative rotation angle between the first rotating member and the base is disposed on the first rotating member;
- and/or
- a second abutting part that limits relative rotation angle between the second rotating member and the base is disposed on the second rotating member, wherein the corresponding opening groove has a top wall, and the first abutting part and/or the second abutting part abut/abuts against the top wall in an unfolded state.
