Abstract

A safety lock includes a releasing component and a locking component. The locking component is movably disposed on a frame releasing component or a stroller frame. The locking component is driven by the releasing component to move relative to the frame releasing component or the stroller frame between a blocking position and a releasing position. The locking component engages with the frame releasing component to restrain the frame releasing component from unlocking the stroller frame or engages with the stroller frame to restrain the stroller frame from being folded when the locking component is located at the blocking position, and the locking component disengages from the frame releasing component to allow the frame releasing component to unlock the stroller frame or disengages from the stroller frame to allow the stroller frame to be folded when the locking component is located at the releasing position.

First claim

What is claimed is:

1. A safety lock adapted for a stroller, the stroller comprising a stroller frame, a locking device and at least one frame releasing component, the stroller frame being switchable between a folded state and an unfolded state, the locking device being for locking the stroller frame to restrain the stroller frame from being folded or for unlocking the stroller frame to allow the stroller frame to be folded, the at least one frame releasing component being for driving the locking device to unlock the stroller frame, the safety lock comprising:
at least one releasing component; and
at least one locking component movably disposed on the at least one frame releasing component or the stroller frame, the at least one locking component being driven by the at least one releasing component to move relative to the at least one frame releasing component or the stroller frame between a blocking position and a releasing position, the at least one locking component engaging with the at least one frame releasing component to restrain the at least one frame releasing component from unlocking the stroller frame by the locking device or engaging with the stroller frame to restrain the stroller frame from being folded when the at least one locking component is located at the blocking position, and the at least one locking component disengaging from the at least one frame releasing component to allow the at least one frame releasing component to unlock the stroller frame by the locking device or disengaging from the stroller frame to allow the stroller frame to be folded when the at least one locking component is located at the releasing position.

2. The safety lock of claim 1 , further comprising at least one first resilient component disposed between the at least one locking component and one of the stroller frame and the at least one frame releasing component where the at least one locking component is disposed, a first end of the at least one first resilient component being connected to or abutting against the at least one locking component, a second end of the at least one first resilient component being connected to or abutting against the one of the stroller frame and the at least one frame releasing component where the at least one locking component is disposed, and the at least one first resilient component being for biasing the at least one locking component to move to the blocking position.

3. The safety lock of claim 2 , wherein the at least one releasing component includes a driving profile, the at least one locking component abuts against the driving profile, and the at least one locking component is driven by the driving profile and the at least one first resilient component to switch between the releasing position and the blocking position when the at least one releasing component moves.

4. The safety lock of claim 3 , wherein the driving profile is formed on an outer periphery or an inner periphery of the at least one releasing component.

5. The safety lock of claim 4 , wherein the driving profile includes a driving inclined surface or a driving groove.

6. The safety lock of claim 4 , wherein the at least one releasing component is pivotally disposed on the stroller frame or the frame releasing component around a first pivoting axis, and a moving direction of the at least one locking component is substantially parallel to the first pivoting axis of the at least one releasing component.

7. The safety lock of claim 6 , wherein the at least one frame releasing component is pivotally disposed on the stroller frame, the at least one frame releasing component and the at least one releasing component are arranged along the first pivoting axis of the at least one releasing component, the first pivoting axis of the at least one releasing component is substantially collinear or parallel to a pivoting axis of the at least one frame releasing component.

8. The safety lock of claim 6 , wherein the at least one releasing component comprises a stopping protrusion for restraining a range of a pivoting movement of the at least one releasing component around the first pivoting axis.

9. The safety lock of claim 2 , further comprising an operating component movably linked to the at least one releasing component for driving the at least one locking component to move to the releasing position by the at least one releasing component.

10. The safety lock of claim 9 , wherein the safety lock comprises two releasing components and two locking components, the two releasing components are located at two lateral sides of the stroller frame, the two locking components are located at the two lateral sides of the stroller frame, and two ends of the operating component are connected to the two releasing components located at the two lateral sides of the stroller frame.

11. The safety lock of claim 9 , further comprising a second resilient component connected to or abutting against the operating component for biasing the operating component to recover.

12. The safety lock of claim 9 , further comprising at least one linking component disposed between the operating component and the at least one releasing component, and the operating component driving the at least one releasing component by the at least one linking component to drive the at least one locking component to move to the releasing position.

13. The safety lock of claim 12 , wherein the at least one locking component is substantially a step-shaft structure.

14. The safety lock of claim 1 , further comprising at least one linking component disposed between the at least one releasing component and the at least one locking component, and the at least one releasing component driving the at least one locking component to move to the releasing position by the at least one linking component.

15. The safety lock of claim 14 , wherein the at least one locking component is pivotally connected to the stroller frame or the at least one frame releasing component, and a pivoting axis of the at least one locking component is substantially collinear or parallel to a pivoting axis of the at least one frame releasing component.

16. The safety lock of claim 15 , wherein the at least one locking component comprises a first abutting segment and a second abutting segment divided by the pivoting axis of the at least one locking component, the first abutting segment is for abutting against the stroller frame, and the second abutting segment is for abutting against the at least one frame releasing component.

17. The safety lock of claim 16 , wherein an included angle between the first abutting segment and the second abutting segment is less than 90 degrees.

18. The safety lock of claim 14 , wherein a moving direction of the at least one locking component is not parallel to a pivoting axis of the at least one frame releasing component.

19. The safety lock of claim 1 , further comprising at least one third resilient component disposed between the at least one releasing component and one of the stroller frame and the at least one frame releasing component where the at least one releasing component is disposed, a first end of the at least one third resilient component being connected to or abutting against the at least one releasing component, a second end of the at least one third resilient component being connected to or abutting against the one of the stroller frame and the at least one frame releasing component where the at least one releasing component is disposed, and the at least one third resilient component being for biasing the at least
