Brake mechanism for a baby stroller

1. A brake mechanism for a baby stroller, the baby stroller having at least a wheel connected to a toothed portion and a pair of push arms capable of being repositioned by rotation to allow the stroller to be pushed forward or rearward, the brake mechanism comprising:

a braking block for operatively stopping the baby stroller by engaging with the toothed portion;

a connecting assembly for operatively actuating the braking block; and

an actuator, operatively secured to the push arm and associated with the connecting assembly for indirectly driving the brake mechanism, the actuator having a base, a control member, a release element, and an upper flexible connector, the upper flexible connector having an upper end connected with the control member via a pin and a lower end connected to the connecting assembly, the base being connected to one of the push arms, the control member being pivotally connected to the base, and the release element being lockable and releasably engaged with the control member when in a braking position;

wherein the release element has a protruding positioning portion for locking the control member in the braking position.

2. The brake mechanism for a baby stroller as claimed in claim 1 , wherein the actuator further has a pin for connecting one end of the upper flexible connector and the control member, so as to pull the upper flexible connector by rotation of the control member about the base.

3. The brake mechanism for a baby stroller as claimed in claim 1 , wherein the connecting assembly has a driving slider, a pulling slider and a lower flexible connector, the driving slider being movably secured to one of the push arms, the pulling slider being reciprocally associated with the braking block of the brake mechanism via the lower flexible connector, and the driving slider being reciprocally associated with the control member of the actuator via the upper flexible connector and abutting on the pulling slider for indirectly associating with the brake mechanism.

4. The brake mechanism for a baby stroller as claimed in claim 1 , further comprising a wheel base, a driving element and a resilient element, the wheel base being connected with the leg frame of the stroller and movably receiving the braking block and the resilient element, and being connected with a wheel hub and the driving element, the wheel hub having the toothed portion for engaging with the braking block.

5. The brake mechanism for a baby stroller as claimed in claim 4 , wherein the driving element has a part connected with one end of the lower flexible connector, and rotates about the wheel base for driving the braking block into a braking position.

6. The brake mechanism for a baby stroller as claimed in claim 4 , wherein the resilient element is biased on the braking block so as to leave the toothed portion of the wheel hub, until the driving element is pulled by the lower flexible connector.

7. The brake mechanism for a baby stroller as claimed in claim 4 , wherein the brake mechanism further includes a connecting bar for interconnecting the driving elements at both sides of the stroller, so as to simultaneously brake the wheels on both sides of the stroller.

8. A brake mechanism for a baby stroller, the baby stroller having a plurality of wheels and a pair of push arms capable of being moved forward or rearward, the brake mechanism comprising:

a braking block for operatively stopping the baby stroller;

a connecting assembly operatively associated with the braking block; and

an actuator, operatively secured to the push arm and associated with the connecting assembly for indirectly driving the brake mechanism, the actuator having a base, a control member, a release element, and an upper flexible connector, the base being connected to one of the push arms, the control member being pivotally connected to the base and associated with the connecting assembly via the upper flexible connector, and the release element being lockable and releasably engaged with the control member when in a braking position;

wherein the release element has a protruding positioning portion for locking the control member in the braking position;

wherein the actuator further has a pin for connecting one end of the upper flexible connector and the control member, so as to pull the upper flexible connector by rotation of the control member about the base; and

wherein the push arm and the base both have a slot for guiding movement of the pin.

9. A brake mechanism for a baby stroller, the baby stroller having a plurality of wheels and a pair of push arms capable of being moved forward or rearward, the brake mechanism comprising:

a braking block for operatively stopping the baby stroller;

a connecting assembly operatively associated with the braking block; and

an actuator, operatively secured to the push arm and associated with the connecting assembly for indirectly driving the brake mechanism, the actuator having a base, a control member, a release element, and an upper flexible connector, the base being connected to one of the push arms, the control member being pivotally connected to the base and associated with the connecting assembly via the upper flexible connector, and the release element being lockable and releasably engaged with the control member when in a braking position;

wherein the release element has a protruding positioning portion for locking the control member in the braking position;

wherein the connecting assembly has a driving slider, a pulling slider and a lower flexible connector, the driving slider being movably secured to the push arm, the pulling slider being reciprocally associated with the braking block of the brake mechanism via the lower flexible connector, and the driving slider being reciprocally associated with the control member of the actuator via the upper flexible connector and abutting on the pulling slider for indirectly associating with the brake mechanism; and

wherein the driving slider has a first protruded block for abutting a first abutting face of the pulling slider, and has a second protruded block for abutting a second abutting face of the pulling slider, so as to drive the pulling slider.
