Abstract

An indicator assembly of a supporting leg device for a safety seat and a safety seat are provided. The indicator assembly includes: an indicator housing having an indicator window; an indicating member including a first area and a second area which are adjacent to each other; a first elastic member driving the indicating member to pivot to a first position; an pushing member including a ground contact end that protrudes from the bottom of the supporting leg device; a traction member movably positioned within a hollow sleeve, wherein a first end of the traction member protrudes from the upper end of the sleeve and is fixed to the indicating member, and a second end of the traction member protrudes from the lower end of the sleeve and is configured that an upward movement of the pushing member drives an upward movement of the second end of the traction member.

First claim

What is claimed is:

1. An indicator assembly of a supporting leg device for a safety seat, wherein the indicator assembly comprises:
an indicator housing adapted to be positioned at a top of the supporting leg device and having an indicator window that is formed by penetrating the indicator housing;
an indicating member including a first area and a second area which are adjacent to each other and have different colors or patterns, the indicating member being pivotally accommodated in the indicator housing so that the first area and the second area can be alternatively exposed from the indicator window;
a first elastic member contacting with the indicating member and driving the indicating member to pivot to a first position;
a pushing member adapted to be placed inside the supporting leg device and movable up and down relative to a bottom of the supporting leg device, the pushing member including a ground contact end adapted to protrude from the bottom of the supporting leg device;
a traction member movably positioned within a hollow sleeve, wherein the sleeve has an upper end configured to be immobile relative to the top of the supporting leg device, and a lower end configured to be immobile relative to the bottom of the supporting leg device; wherein a first end of the traction member protrudes from the upper end of the sleeve and is fixed to the indicating member, so that the indicating member is pulled so as to pivot to a second position, and a second end of the traction member protrudes from the lower end of the sleeve and is configured so that an upward movement of the pushing member drives an upward movement of the second end of the traction member.

2. The indicator assembly of the supporting leg device for a safety seat according to claim 1 , wherein
the indicator housing is adapted to be connected to an upper end of a first tube of the supporting leg device.

3. The indicator assembly of the supporting leg device for the safety seat according to claim 2 , wherein the lower end of the sleeve is adapted to be positioned close to an upper end of a second tube of the supporting leg device that is slidably disposed inside the first tube of the supporting leg device, and the pushing member extends upward and a height of an upper part of the pushing member exceeds beyond a height of the lower end of the sleeve, and the second end of the traction member is fixed to the upper part of the pushing member.

4. The indicator assembly of the supporting leg device for the safety seat according to claim 2 , wherein an upper part of the pushing member is adapted to pass through a retaining member provided at an upper end of a second tube of the supporting leg device that is slidably disposed inside the first tube of the supporting leg device, and the lower end of the sleeve is adapted to be fixed to the retaining member.

5. The indicator assembly of the supporting leg device for the safety seat according to claim 2 , wherein the lower end of the sleeve is positioned close to the bottom of the supporting leg device, and the pushing member extends upward and a height of an upper part of the pushing member exceeds beyond a height of the lower end of the sleeve, and the second end of the traction member is fixed to the upper part of the pushing member.

6. The indicator assembly of the supporting leg device for the safety seat according to claim 2 , wherein a remaining member is provided at the upper end of the second tube, and the sleeve is adapted to be wound into a first loop in a space under the remaining member within the supporting leg device.

7. The indicator assembly of the supporting leg device for the safety seat according to claim 6 , wherein a lower part of the remaining member extends from a sleeve remaining part, and the first loop is suspended on the sleeve remaining part.

8. The indicator assembly of the supporting leg device for the safety seat according to claim 1 , wherein an upper part of the pushing member is adapted to be positioned over the sleeve lower end fixing member provided with the bottom of the supporting leg device, and the lower end of the sleeve is adapted to be fixed to the sleeve lower end fixing member.

9. The indicator assembly of the supporting leg device for the safety seat according to claim 1 , wherein a second elastic member is connected to the pushing member, and the second elastic member forces the pushing member to move downward relative to the bottom of the supporting leg device.

10. The indicator assembly of the supporting leg device for the safety seat according to claim 1 , wherein the lower end of the sleeve is adapted to be positioned close to the bottom of the supporting leg device, and a driving member is arranged on the pushing member, and the driving member extends upward and a height of an upper part of the driving member extends beyond a height of a lower end of the sleeve, and the second end of the traction member is fixed to the upper part of the driving member.

11. The indicator assembly of the supporting leg device for the safety seat according to claim 10 , wherein a third elastic member is connected to the driving member, and the third elastic member forces the driving member to move downward relative to the bottom of the supporting leg device.

12. The indicator assembly of the supporting leg device for the safety seat according to claim 1 , wherein the sleeve includes a first section close to the upper end and a second section close to the lower end, wherein the first section is a leather sleeve, the second section is a spring sleeve, and the first section and the second section are connected at a node.

13. The indicator assembly of the supporting leg device for the safety seat according to claim 12 , wherein the second section of the sleeve is adapted to be wound into a second loop, and the second loop is adapted to be wound around a post member within the supporting leg device.

14. The indicator assembly of the supporting leg device for the safety seat according to claim 1 , wherein the upper end of the sleeve is adapted to be fixed to a sleeve upper end fixing member fixed to the top of the supporting leg device.

15. The indicator assembly of the supporting leg device for the safety seat according to claim 1 , wherein a bottom of the ground contact end is made of a thermoplastic elastomer material.

16. The indicator assembly of the supporting leg device for the safety seat according to claim 1 , wherein when the ground contact end of the pushing member does not touch the ground, the indicating member pivots to the first position and the first area is exposed from the indicating window.

17. The indicator assembly of the supporting leg device for the safety seat according to claim 1 , wherein when the ground contact end of the pushing member touches the ground, the pushing member moves upward relative to the bottom of the supporting leg device to drive the second end of the traction member to move upward, the first end of the traction member moves downward relative to the top of the supporting leg device to pull the indicating member, the indicating member pivots to the second position, and the second area is exposed from the indicating window.
