Abstract

A baby carrier includes a frame body and a locking mechanism. The frame body is configured to be selectively folded or unfolded, and includes a rod and a pivotable joint-component. The rod is connected to the joint-component, and a pivot of the joint-component is configured to deviate from a connection between the rod and the joint-component. The locking mechanism is slidably arranged on the rod, and is movable between a locking position restricting pivoting of the joint-component and a releasing position allowing the pivoting of the joint-component.

Claims (37)

1 . A baby carrier, comprising:

a frame body, configured to be selectively folded or unfolded and comprising a rod and a pivotable joint-component, the rod being connected to the joint-component, and a pivot of the joint-component being positioned on an axis offset from a connection between the rod and the joint-component; and

a locking mechanism, slidably arranged on the rod, and movable between a locking position restricting pivoting of the joint-component and a releasing position allowing the pivoting of the joint-component,

wherein

when the frame body is in a folded state, the locking mechanism engages with the joint-component, and the pivoting of the joint-component is restricted by the locking mechanism such that the frame body is locked in the folded state; and

when the frame body is in an unfolded state, the pivoting of the joint-component is free from being restricted by the locking mechanism.

2 . The baby carrier according to claim 1 , wherein the locking mechanism comprises:

a locking member, engaging with the joint-component to restrict the pivoting of the joint-component when the locking mechanism is in the locking position; and

a resetting member, configured to constantly drive the locking member to move to the locking position.

3 . The baby carrier according to claim 2 , wherein:

the locking mechanism further comprises a stopping member, and the stopping member is connected to the rod; and

one end of the resetting member abuts against or is connected to the stopping member, and another end of the resetting member is adapted to push the locking member.

4 . The baby carrier according to claim 1 , wherein the locking mechanism further comprises a releasing component, and the releasing component is adapted to operatively switch the locking mechanism from the locking position to the releasing position.

5 . The baby carrier according to claim 2 , wherein:

at least a portion of the rod, where the locking member is arranged, is hollow, and the locking member is arranged in the hollow portion of the rod, and is movable in a direction parallel to an axial direction of the rod;

the locking mechanism further comprises a releasing component; the releasing component is connected to the locking member, and the releasing component comprises an operating member and a second connecting member; and

the operating member is arranged on an outer side of the rod; one end of the second connecting member is connected to the operating member, and another end of the second connecting member is inserted in the rod and connected to the locking member.

6 . The baby carrier according to claim 5 , wherein the rod is provided with a limiting elongated-groove forming a travel range of a sliding of the locking member, and the second connecting member is inserted in the limiting elongated-groove to connect the operating member and the locking member.

7 . The baby carrier according to claim 5 , wherein the operating member is an operating sleeve fitting over the outer side of the rod.

8 . The baby carrier according to claim 5 , wherein the locking mechanism further comprises a fixing member; the fixing member is arranged inside the rod and is movable along a direction parallel to a longitudinal direction of the rod; and the locking member is connected to the releasing component through the fixing member.

9 . The baby carrier according to claim 8 , wherein the fixing member is a fixing sleeve; the fixing member has a fixing chamber extending along a direction parallel to the longitudinal direction of the rod; and the locking member is inserted in the fixing chamber.

10 . The baby carrier according to claim 8 , wherein the locking mechanism further comprises a first connecting member, and the locking member is connected to the fixing member through the first connecting member.

11 . The baby carrier according to claim 2 , wherein:

the joint-component comprises a first joint and a second joint; the first joint and the second joint are pivotally connected by the pivot; the first joint has a receiving hole, and the second joint has a locking hole; and

the locking member comprises a free end; the free end is inserted in and engages with the receiving hole and the locking hole when the locking member is in the locking position; and the free end disengages from at least one of the receiving hole and the locking hole when the locking member is in the releasing position.

12 . The baby carrier according to claim 11 , wherein when the frame body is in the folded state, the receiving hole and the locking hole overlap, and the free end is configured to be inserted in an overlapped area of the receiving hole and the locking hole.

13 . The baby carrier according to claim 11 , wherein both the receiving hole and the locking hole are positioned on an axis offset from the pivot of the joint-component.

14 . The baby carrier according to claim 2 , wherein the locking member is a pin.

15 . The baby carrier according claim 1 , wherein there are two joint-components arranged oppositely at two ends of the rod, and the rod is connected between the two joint-components.

16 . The baby carrier according to claim 15 , wherein pivots of the two joint-components are located on the same straight line.

17 . The baby carrier according to claim 11 , wherein the first joint is connected to a hand-gripping component of the frame body, and the second joint is connected to a rear leg support rod of the frame body; and

the first joint is provided with a boss, and a guide groove is formed on the second joint to guide the boss to slide therealong.

18 . The baby carrier according to claim 11 , wherein the first joint is formed by fastening two first half-joints, and the second joint is clamped between the two first half-joints and is pivotable relative to the first joint.

19 . The baby carrier according to claim 11 , wherein the joint-component further comprises a first housing covering the first joint and a second housing covering the second joint.

20 . The baby carrier according to claim 15 , wherein the rod comprises a first rod-portion connected to a first joint-component, a second rod-portion connected to a second joint-component, and a third rod-portion connected between the first rod-portion and the second rod-portion;

an axis of the first rod-portion and an axis of the second rod-portion coincide with each other and are parallel to the pivot of the joint-component; and

the third rod-portion is an upwardly convex curved rod.
