Leg frame and child chair having the same
When a leg frame is assembled to a seat, the child chair is used as a high chair. When the leg frame is detached from the seat, the child chair may be served as a booster. Legs of the detached leg frame are further assembled with a footrest for storage purpose. The footrest has coupling slots that are formed by resilient arms to hold the detached legs. The footrest may also serve as a pedal for feet when the leg frame is assembled to the seat.
1. A leg frame, which is detachably coupled with a seat, comprising:
a supporting frame detachably coupling with a coupling section of the seat, the supporting frame comprising two first legs and two second legs; and
a footrest mounted on the two first legs, wherein the footrest comprises a mounting section and the two second legs are coupled with the mounting section when the supporting frame is detached from the seat.
2. The leg frame of claim 1 , wherein the coupling section comprises a plurality of openings, the two first legs and the two second legs inserting into a corresponding opening for coupling with the coupling section.
3. The leg frame of claim 1 , wherein the mounting section comprises two coupling slots for coupling with the second legs respectively.
4. The leg frame of claim 3 , wherein a wall that defines each coupling slot forms a resilient arm so that the corresponding second leg is held therebetween.
5. The leg frame of claim 1 , wherein the first legs and the second legs of the supporting frame are pipes, each comprising a fastening component for coupling with the coupling section so as to couple the supporting frame to the seat.
6. The leg frame of claim 5 , wherein each of the first legs and the second legs comprises a first hole at a pipe wall, and the fastening component comprises a protrusion for extending through the first hole.
7. The leg frame of claim 5 , wherein the fastening component is a V-shape resilient piece.
8. The leg frame of claim 1 , wherein the supporting frame comprises a lump for cooperating with a groove of the seat.
9. The leg frame of claim 1 , wherein the supporting frame comprises a bending section such that the supporting frame couples with the coupling section in a tilting angle relative to the seat.
10. A child chair comprising:
a seat;
a supporting frame comprising a plurality of legs for detachably coupling with the seat; and
a footrest mounted on the supporting frame, wherein the footrest comprises a mounting section and the legs of the supporting frame are stored with the footrest by coupling with the mounting section;
wherein the child chair is convertible between a high chair status in which the supporting frame is coupled to the seat and a booster status wherein the plurality of legs of the supporting frame is detached from the seat and stored with the footrest.
11. The child chair of claim 10 , wherein the mounting section comprises a plurality of coupling slots for coupling with the legs respectively.
12. The child chair of claim 11 , wherein a wall that defines each coupling slot forms a resilient arm so that the corresponding leg is held therebetween.
13. The child chair of claim 10 , wherein the seat comprises a plurality of openings, the legs are inserted into corresponding opening for coupling with the seat.
14. The child chair of claim 13 , wherein each leg comprises a fastening component for coupling with the seat after the legs are inserted into corresponding opening.
