Abstract
A chair includes a frame unit including a seat frame, a leg rest that is pivotally mounted to the seat frame, and a rest adjusting mechanism that is connected between the leg rest and the seat frame. The rest adjusting mechanism is convertible between an unlocked state, where the leg rest is permitted to pivot relative to the seat frame, and a locked state, where the leg rest is not permitted to pivot relative to the seat frame.
Claims10
A chair comprising a frame unit including:
- a seat frame;
- a leg rest that is pivotally mounted to said seat frame;
- and
- a rest adjusting mechanism that is connected between said leg rest and said seat frame;
- wherein said rest adjusting mechanism is convertible between
- an unlocked state, where said leg rest is permitted to pivot relative to said seat frame, and
- a locked state, where said leg rest is not permitted to pivot relative to said seat frame:
- wherein said rest adjusting mechanism includes an operating member, a locking member, and a positioning rod that has a plurality of engaging holes and that is co-movably connected to said leg rest,
- wherein said frame unit further includes:
- two front legs connected pivotally to said seat frame and proximate to said leg rest;
- two rear legs disposed at a rear side of said front legs and connected to said seat frame;
- and
- a bottom frame connected to said front and rear legs, and having a front rod that is proximate to said front legs, said rest adjusting mechanism being mounted between said front rod and said leg rest.

- wherein said rest adjusting mechanism includes an operating member, a locking member, and a positioning rod that has a plurality of engaging holes and that is co-movably connected to said leg rest;
- and
- wherein said seat frame includes inner and outer tubes coupled telescopically to each other, and a seat adjusting mechanism mounted to said inner tube and said outer tube, and convertible between an engaging state, where movement between said inner and outer tubes is not allowed, and a disengaging state, where movement between said inner and outer tubes is allowed.

- a seat frame;
- a leg rest that is pivotally mounted to said seat frame;
- and
- a rest adjusting mechanism that is connected between said leg rest and said seat frame;
- wherein said rest adjusting mechanism is convertible between
- an unlocked state, where said leg rest is permitted to pivot relative to said seat frame, and
- a locked state, where said leg rest is not permitted to pivot relative to said seat frame;
- wherein said rest adjusting mechanism includes an operating member, a locking member, and a positioning rod that has a plurality of engaging holes and that is co-movably connected to said leg rest;
- wherein said frame unit further includes a back rest, a canopy frame mounted to said back rest, and a canopy adjusting mechanism mounted to said back rest, said canopy adjusting mechanism being convertible between an unfastened state, where a height of said canopy frame relative to said back rest is permitted to be adjusted, and a fastened state, where said canopy frame is fixed to said back rest;
- and
- wherein:
- said back rest includes a rest rod;
- said canopy adjusting mechanism includes a surrounding base that surrounds said rest rod and that is slidable along said rest rod, an actuating member that is mounted on said surrounding base, and a plurality of positioning holes formed on said rest rod of said back rest;
- when said canopy adjusting mechanism is in the fastened state, said actuating member engages one of said positioning holes;
- and
- when said canopy adjusting mechanism is in the fastened state, said actuating member is operable to be disengaged from the one of said positioning holes to convert said canopy adjusting mechanism to the unfastened state, thereby permitting movement of said canopy frame relative to said rest rod.
