Abstract

A rod locking mechanism includes a central hub, a first rod component and a locking component. The first rod component is pivotally connected to the central hub. The first rod component includes an abutting portion. The abutting portion is movable between a first position and a second position when the first rod component pivots relative to the central hub. The locking component is movably disposed on the central hub. The abutting portion is located at a first side of the locking component when the abutting portion is located at the first position. The abutting portion drives the locking component to move when the abutting portion moves from the first position toward the second position, and the abutting portion abuts against a second side of the locking component opposite to the first side of the locking component when the abutting portion is located at the second position.

First claim

What is claimed is:

1. A rod locking mechanism comprising:
a central hub;
a first rod component pivotally connected to the central hub, the first rod component comprising an abutting portion, the abutting portion being movable between a first position and a second position when the first rod component pivots relative to the central hub; and
a locking component movably disposed on the central hub, the abutting portion being located at a first side of the locking component when the abutting portion is located at the first position, the abutting portion driving the locking component to move when the abutting portion moves from the first position toward the second position, and the abutting portion abutting against a second side of the locking component opposite to the first side of the locking component when the abutting portion is located at the second position.

2. The rod locking mechanism of claim 1 , wherein the locking component is slidably disposed on the central hub, and the abutting portion pushes the locking component to slide when the abutting portion moves from the first position toward the second position.

3. The rod locking mechanism of claim 2 , further comprising a first resilient component for biasing the locking component to recover, a first end of the first resilient component abutting against the central hub, and a second end of the first resilient component abutting against the locking component.

4. The rod locking mechanism of claim 3 , wherein an accommodating slot is formed on the locking component for accommodating the second end of the first resilient component.

5. The rod locking mechanism of claim 2 , wherein the locking component comprises a driven edge, and the locking component is driven to slide by cooperation of the driven edge and the abutting portion when the abutting portion moves from the first position toward the second position.

6. The rod locking mechanism of claim 5 , wherein the locking component further comprises an abutting edge, and the locking component abuts against the abutting portion by the abutting edge when the abutting portion is located at the second position.

7. The rod locking mechanism of claim 6 , wherein the driven edge and the abutting edge are inclined relative to a sliding direction of the locking component, a sign of a slope of the driven edge relative to the sliding direction of the locking component is opposite to a sign of a slope of the abutting edge relative to the sliding direction of the locking component, and an absolute value of the slope of the driven edge relative to the sliding direction of the locking component is greater than an absolute value of the slope of the abutting edge relative to the sliding direction of the locking component.

8. The rod locking mechanism of claim 2 , wherein the central hub comprises a fixing base, and the locking component is slidably disposed on the fixing base.

9. The rod locking mechanism of claim 8 , wherein at least one long hole is formed on the fixing base, at least one sliding slot is formed on the locking component, at least one wall of the at least one long hole is inserted into the at least one sliding slot, the locking component is slidable along a longitudinal direction of the long hole by cooperation of the at least one sliding slot and the at least one wall of the at least one long hole.

10. A stroller comprising:
a rod locking mechanism comprising:
a central hub;
a first rod component pivotally connected to the central hub, the first rod component comprising an abutting portion, the abutting portion being movable between a first position and a second position when the first rod component pivots relative to the central hub; and
at least one locking component movably disposed on the central hub, the abutting portion being located at a first side of the at least one locking component when the abutting portion is located at the first position, the abutting portion driving the at least one locking component to move when the abutting portion moves from the first position toward the second position, and the abutting portion abutting against a second side of the at least one locking component opposite to the first side of the at least one locking component when the abutting portion is located at the second position; and

a second rod component fixed on the central hub, the first rod component being pivotally movable relative to the second rod component.

11. The stroller of claim 10 , further comprising a linking component and a third rod component pivotally connected to the central hub, and two ends of the linking component being respectively pivotally connected to the first rod component and the third rod component.

12. The stroller of claim 11 , wherein the first rod component is one of a handle and a front foot, the third rod component is another one of the handle and the front foot, the second rod component is a rear foot, the at least one at least one locking component comprises two locking components, and the two locking components respectively abut against the first rod component and the third rod component when the first rod component and the third rod component are pivotally folded relative to the second rod component.

13. The stroller of claim 10 , wherein the at least one locking component is slidably disposed on the central hub, and the abutting portion pushes the at least one locking component to slide when the abutting portion moves from the first position toward the second position.

14. The stroller of claim 13 , wherein the rod locking mechanism further comprises a first resilient component for biasing the at least one locking component to recover, a first end of the first resilient component abuts against the central hub, and a second end of the first resilient component abuts against the at least one locking component.

15. The stroller of claim 14 , wherein an accommodating slot is formed on the at least one locking component for accommodating the second end of the first resilient component.

16. The stroller of claim 13 , wherein the at least one locking component comprises a driven edge, and the at least one locking component is driven to slide by cooperation of the driven edge and the abutting portion when the abutting portion moves from the first position toward the second position.

17. The stroller of claim 16 , wherein the at least one locking component further comprises an abutting edge, and the at least one locking component abuts against the abutting portion by the abutting edge when the abutting portion is located at the second position.

18. The stroller of claim 17 , wherein the driven edge and the abutting edge are inclined relative to a sliding direction of the at least one locking component, a sign of a slope of the driven edge relative to the sliding direction of the at least one locking component is opposite to a sign of a slope of the abutting edge relative to the sliding direction of the at least one locking component, and an absolute value of the slope of the driven edge relative to the sliding direction of the at least one locking component is greater than an absolute value of the slope of the abutting edge relative to the sliding direction of the at least one locking component.

19. The stroller of claim 13 , wherein the central hub comprises a fixing base, and the at least one locking component is slidably disposed on the fixing base.

20. The stroller of claim 19 , wherein at least one long hole is formed on the fixing base, at least one sliding slot is formed on the at least one lo
