Abstract

A rotatable tray is installed on a child seat for accommodating a container, and the rotatable tray includes a platform, a fixing base, a positioning base, a resilient component and a supporting base. The platform includes a communicating chamber, and the fixing base is fixed in the communicating chamber. The positioning base includes a first engaging portion, and the positioning base is slidably disposed in the communicating chamber. The resilient component is disposed between the fixing base and the positioning base. The supporting base is connected to the platform, an engaging base protrudes from an end of the supporting base, and a second engaging portion is disposed on the supporting base. The engaging base is pivoted in the communicating chamber so that the platform can rotate relative to the supporting base. The resilient component drives the first engaging portion to selectively engage with the second engaging portion.

Claims

1. A rotatable tray installed on a child seat for accommodating a container, and the rotatable tray comprising:

a platform comprising a communicating chamber;

a fixing base fixed in the communicating chamber of the platform;

a positioning base comprising a first engaging portion, and the positioning base being slidably disposed in the communicating chamber of the platform;

a resilient component disposed between the fixing base and the positioning base; and

a supporting base connected to the platform, an engaging base protruding from an end of the supporting base, a second engaging portion being disposed on the supporting base, the engaging base being pivoted in the communicating chamber so that the platform rotates relative to the supporting base, and the resilient component driving the first engaging portion to selectively engage with the second engaging portion.

2. The rotatable tray of claim 1, wherein the positioning base is circumferentially fixed and slidably up and down disposed in the communicating chamber, the first engaging portion is disposed on an end of the positioning base facing the second engaging portion, and the first engaging portion protrudes from the end of the positioning base.

3. The rotatable tray of claim 2, wherein the first engaging portion comprises a plurality of first engaging teeth, the second engaging portion correspondingly comprises a plurality of second engaging teeth surrounding a central axis of the engaging base, and the resilient component is for driving the plurality of first engaging teeth to engage with the plurality of second engaging teeth.

4. The rotatable tray of claim 3, wherein the first engaging portion comprises twelve first engaging teeth, the second engaging portion comprises twelve second engaging teeth, and an angle between two adjacent first engaging teeth or two adjacent second engaging teeth is 30 degrees substantially.

5. The rotatable tray of claim 2, wherein a stopping protrusion is formed on an outer sidewall of the engaging base, a sliding slot is formed on an inner sidewall of the positioning base, the sliding slot is a curve-shaped concave structure, the stopping protrusion is slidably installed in the sliding slot, and the stopping protrusion slides in the sliding slot as the positioning base rotates.

6. The rotatable tray of claim 5, wherein the sliding slot is a curve-shaped slot and an angle of the curve-shaped slot is 180 degrees substantially.

7. The rotatable tray of claim 1, wherein the fixing base comprises a hollow chamber, an opening is formed on an end of the hollow chamber, and two resilient arms protrude from inner sides of the fixing base.

8. The rotatable tray of claim 7, wherein an annular slot is formed on an end of the engaging base, the engaging base is pivoted on the fixing base, and the two resilient arms are engaged inside the annular slot.

9. The rotatable tray of claim 1, wherein the platform further comprises a pivoting portion and at least one containing space, and the communicating chamber is connected to the pivoting portion.

10. The rotatable tray of claim 9, wherein a concave portion is formed on a sidewall of the containing space, a shape of the container is corresponding to a shape of the containing space, and a protruding portion is formed on an outer sidewall of the container for engaging with the concave portion so as to fix the container in the containing space.

11. The rotatable tray of claim 1, wherein the child seat comprises a T-shaped connecting portion, a connecting slot is correspondingly disposed on the supporting base, and the T-shaped connecting portion is inserted into the connecting slot.

12. The rotatable tray of claim 11, wherein an engaging hole is disposed on the T-shaped connecting portion, the rotatable tray further comprises an engaging component and a first spring, a central portion of the engaging component is pivoted on the supporting base, an engaging hook is formed on an end of the engaging component, a quick release pressing portion is formed on the other end of the engaging component, and the first spring is disposed between an inner sidewall of the supporting base and the quick release pressing portion so as to drive the engaging hook to engage with the engaging hole.

13. The rotatable tray of claim 1, wherein the supporting base further comprises a first connecting component and a second connecting component, a pivoting shaft is formed on an end of the second connecting component, and the first connecting component is pivoted on the second connecting component through the pivoting shaft.

14. The rotatable tray of claim 13, wherein the first connecting component is pivoted on the second connecting component in a front and rear direction of the child seat.

15. The rotatable tray of claim 14, further comprising a positioning mechanism disposed between the first connecting component and the second connecting component, and the positioning mechanism being for fixing the first connecting component on the second connecting component.

16. The rotatable tray of claim 15, wherein the positioning mechanism comprises:

a gear slidably sheathing on the pivoting shaft;

a second spring disposed between the gear and the first connecting component; and

a third engaging portion disposed on the second connecting component and surrounding the pivoting shaft, the third engaging portion comprising a plurality of third engaging teeth, and the second spring driving the gear to selectively engage with the third engaging portion as the first connecting component rotates.
