Abstract

A stroller includes a stroller frame, a reversible member pivoted to the stroller frame, and a reversible mechanism. The reversible mechanism locks the reversible member at different positions and includes a sliding sleeve, a release actuator movably disposed on the reversible member and linked with the sliding sleeve, and anchoring portions disposed on at least two different positions. The sliding sleeve movably jackets the reversible member and is selectively engaged with any anchoring portion. The sliding sleeve moves together with the release actuator or is directly operated for releasing the anchoring portion, so as to make the reversible member rotatable to another position. Since the release actuator is linked with the sliding sleeve, the release actuator can be disposed at a position easy to operate, so that the handle reversing operation can be performed conveniently and quickly. Furthermore, the reversible mechanism has a simple structural design.

First claim

What is claimed is:

1. A stroller comprising:
a stroller frame;
a reversible member pivoted to the stroller frame; and
a reversible mechanism locking the reversible member at different positions relative to the stroller frame and comprising:
anchoring portions disposed on at least two different positions of the stroller frame;
a sliding sleeve movably jacketing the reversible member, the sliding sleeve being selectively engaged with any one of the anchoring portions for locking the reversible member at the different positions relative to the stroller frame;
a release actuator protrusively disposed on the reversible member and linked with the sliding sleeve, the sliding sleeve being switched between a locking position and a releasing position with movement of the release actuator or being directly operated for locking or releasing the anchoring portion, the release actuator being slidable along a lengthwise direction of the reversible member, an avoiding hole being formed on the release actuator and having an opening, and the avoiding hole being a long hole for guiding and limiting movement of the release actuator; and
a driving member slidably disposed in the reversible member and linked with the sliding sleeve, the sliding sleeve being slidably disposed on the reversible member along the lengthwise direction of the reversible member.

2. The stroller of claim 1 , wherein the stroller further comprises a pivot shaft disposed on the reversible member or the stroller frame, and the reversible member is pivotally connected to the stroller frame via the pivot shaft.

3. The stroller of claim 1 , wherein the reversible member is a handle.

4. The stroller of claim 1 , wherein the reversible mechanism further comprises a linking member disposed in the reversible member, a first end of the linking member is connected to the release actuator, a second end of the linking member is connected to the driving member, a containing cavity is formed on the reversible member, and the driving member and the linking member are slidably disposed in the containing cavity.

5. A reversible mechanism disposed on a stroller, the stroller comprising a stroller frame and a reversible member pivoted to the stroller frame, the reversible mechanism locking the reversible member at different positions relative to the stroller frame and comprising:
anchoring portions disposed on at least two different positions of the stroller frame;
a sliding sleeve movably jacketing the reversible member, the sliding sleeve being selectively engaged with any one of the anchoring portions for locking the reversible member at the different positions relative to the stroller frame;
a release actuator protrusively disposed on the reversible member and linked with the sliding sleeve, the sliding sleeve being switched between a locking position and a releasing position with movement of the release actuator or being directly operated for locking or releasing the anchoring portion, the release actuator being slidable along a lengthwise direction of the reversible member, an avoiding hole being formed on the release actuator and having an opening, and the avoiding hole being a long hole for guiding and limiting movement of the release actuator; and
a driving member slidably disposed in the reversible member and linked with the sliding sleeve, the sliding sleeve being slidably disposed on the reversible member along the lengthwise direction of the reversible member.

6. The reversible mechanism of claim 5 , wherein the reversible mechanism further comprises a linking member disposed in the reversible member, a first end of the linking member is connected to the release actuator, and a second end of the linking member is connected to the sliding sleeve.

7. The reversible mechanism of claim 6 , wherein the second end of the linking member is connected to the driving member; when the release actuator is operated, the release actuator moves the driving member via the linking member for driving the sliding sleeve to lock or release the anchoring portion.

8. The reversible mechanism of claim 7 , wherein the reversible mechanism further comprises an elastic member disposed in the reversible member, the elastic member is disposed between the reversible member and the driving member, and the elastic member biases the driving member to keep driving the sliding sleeve to be engaged with the anchoring portion.

9. The reversible mechanism of claim 8 , wherein the elastic member is in a compressed state and is disposed between the reversible member and the driving member.

10. The reversible mechanism of claim 8 , wherein the linking member is disposed through the elastic member.

11. The reversible mechanism of claim 7 , wherein the driving member is fixedly connected to the sliding sleeve.

12. The reversible mechanism of claim 6 , wherein the reversible mechanism further comprises a fixing pin, and the fixing pin is fixedly connected to the first end of the linking member and the release actuator.

13. The reversible mechanism of claim 12 , wherein a first guide slot is formed along the lengthwise direction of the reversible member, and the fixing pin is slidably disposed through the first guide slot.

14. The reversible mechanism of claim 6 , wherein the linking member is a rigid link or a flexible steel wire.

15. The reversible mechanism of claim 5 , wherein one of the sliding sleeve and the anchoring portion has a protrusion, the other of the sliding sleeve and the anchoring portion has a recessed structure, the protrusion slides into the recessed structure to lock the sliding sleeve on the anchoring portion, and the protrusion is disengaged from the recessed structure to release the sliding sleeve from the anchoring portion.

16. The reversible mechanism of claim 15 , wherein the recessed structure is an arc-shaped groove, and the protrusion has a convex curved surface mating with the arc-shaped groove.
