Abstract

In one example, a highchair has a seat and a base. The base is attached to the seat such that, when the base is disposed on a surface, the base supports the seat above the surface. The base has a plurality of legs that are rotatable so as to transition the highchair between a raised position and a lowered position. In the raised position, the seat is disposed at a first height and the plurality of legs together define a first footprint that has a first cross-sectional area in a select plane. In the lowered position, the seat is disposed at a second height, lower than the first height, and the plurality of legs together define a second footprint that has a second cross-sectional area in the select plane that is less than the first cross-sectional area.

First claim

What is claimed:

1. A highchair, comprising:
a seat; and
a base attached to the seat such that, when the base is disposed on a surface, the base supports the seat above the surface, the base comprising a plurality of legs and a support connected to the seat and coupled to the plurality of legs such that the support is translatable along the plurality of legs so as to cause movement of the seat along the vertical direction and to cause the plurality of legs to rotate and translate horizontally, so as to transition the highchair between 1) a raised position, wherein the seat is disposed at a first height and the plurality of legs together define a first footprint that has a first cross-sectional area in a select plane, and 2) a lowered position, wherein the seat is disposed at a second height, lower than the first height, and the plurality of legs together define a second footprint that has a second cross-sectional area in the select plane that is less than the first cross-sectional area.

2. The highchair of claim 1 , wherein the highchair is configured such that movement of the seat from the raised position to the lowered position causes the plurality of legs to rotate inwardly towards a space defined between the legs, and movement of the seat from the lowered position to the raised position causes the plurality of legs to rotate outwardly away from the space.

3. The highchair of claim 1 , wherein each leg extends from the surface at a first angle when the highchair is in the raised position and a second angle when the highchair is in the lowered position, the second angle being different from the first angle.

4. The highchair of claim 1 , wherein the highchair can be transitioned between the raised position and the lowered position without changing a length of each of the plurality of legs.

5. The highchair of claim 1 , wherein the support extends downward from the seat and the base further comprises:
a plurality of couplers that couple the support to the plurality of legs such that each coupler is translatable along a respective one of the plurality of legs so as to cause the support to translate along the vertical direction.

6. The highchair of claim 5 , wherein each of one or more of the couplers comprises a slider that is configured to slide along a track defined by a respective one of the plurality of legs.

7. The highchair of claim 5 , wherein the support comprises a shaft.

8. The highchair of claim 1 , wherein the support extends downward from the seat and the base further comprises:
an upper hub coupled to each of the plurality of legs such that the legs are 1) fixed to the upper hub with respect to translation along the vertical direction, and 2) configured to rotate relative to the upper hub; and
a lower hub coupled to each of the plurality of legs below the upper hub such that the lower hub is configured to translate along the plurality of legs along the vertical direction so as to cause the plurality of legs to transition between the first footprint and the second footprint.

9. The highchair of claim 8 , wherein the support is fixed to the lower hub with respect to translation along the vertical direction and translatable relative to the upper hub with respect to the vertical direction.

10. The highchair of claim 8 , wherein the base comprises a plurality of couplers that couple the lower hub to the plurality of legs such that each coupler is translatable along a respective one of the plurality of legs so as to cause the lower hub to translate along the vertical direction.

11. The highchair of claim 1 , wherein the plurality of legs comprises:
a first leg and a second leg that are offset from one another along a lateral direction; and
a third leg and a fourth leg that are offset from one another along the lateral direction, wherein the third and fourth legs are offset from the first and second legs along a longitudinal direction, perpendicular to the lateral direction.

12. The highchair of claim 11 , wherein the first and second legs are spaced from one another by a first distance, and the first and second legs are spaced from the third and fourth legs by a second distance, greater than the first distance.

13. The highchair of claim 1 , comprising at least one lock that is configured to selectively lock the highchair in the raised and lowered positions.

14. The highchair of claim 13 , wherein each of the at least one lock is configured to engage a corresponding one of the legs to lock a position of the seat relative to the corresponding leg.

15. The highchair of claim 13 , comprising an actuator that is configured to actuate each of the at least one lock.

16. A highchair, comprising:
a seat;
a support that is attached to the seat and extends downward therefrom; and
a base comprising a plurality of legs attached coupled to the support such that the support is translatable along the plurality of legs so as to cause movement of the seat along the vertical direction such that 1) the seat is configured to raise and lower relative to the base along a vertical direction, 2) raising the seat causes each of the plurality of legs to move so as to increase a footprint of the base, and 3) lowering the seat causes each of the plurality of legs to move so as to decrease the footprint of the base.

17. The highchair of claim 16 , wherein raising the seat increases a space between the seat and the base, and lowering the seat decreases the space between the seat and the base.

18. The highchair of claim 16 , wherein the seat can be raised and lowered and the footprint can be increased and decreased without changing a length of each of the plurality of legs.

19. The highchair of claim 16 , wherein the highchair is configured such that lowering the seat causes the plurality of legs to rotate inwardly towards a space defined between the legs, and raising the seat causes the plurality of legs to rotate outwardly away from the space.

20. The highchair of claim 16 , wherein each leg extends from the surface at a first angle when the highchair is raised and a second angle when the highchair is lowered, the second angle being different from the first angle.

21. The highchair of claim 16 , wherein the base comprises:
a plurality of couplers that couple the support to the plurality of legs such that each coupler is translatable along a respective one of the plurality of legs so as to cause the support to translate along the vertical direction.

22. The highchair of claim 21 , wherein each of one or more of the plurality of legs has an outer surface that defines a guide configured to guide a respective one of the couplers as the coupler translates along the leg.

23. The highchair of claim 16 , wherein the base comprises:
an upper hub coupled to each of the plurality of legs such that the legs are 1) fixed to the upper hub with respect to translation along the vertical direction, and 2) configured to pivot relative to the upper hub; and
a lower hub coupled to each of the plurality of legs below the upper hub such that the lower hub is configured to translate along the plurality of legs along the vertical direction so as to cause the footprint to increase and decrease.

24. The highchair of claim 23 , wherein the support is fixed to the lower hub with respect to translation along the vertical direction and translatable relative to the upper hub with respect to the vertical direction.

25. The highchair of claim 23 , wherein the bas
