Abstract

An infant support structure includes a frame, a seat portion rotatably coupled to the frame so that the seat portion is movably coupled to the frame, an engagement member coupled to the seat portion, and a lock bar pivotally coupled to the lower portion of the frame, the lock bar movable between a first position disengaged from the engagement member thereby permitting swinging motion of the seat portion, and a second position engaging the engagement member and inhibiting swinging motion of the seat portion.

Claims

1. An infant swing, comprising:

a frame;

a support arm movably coupled to the frame;

a seat portion coupled to the support arm, the seat portion being movable relative to the frame; and

a locking mechanism including a first locking portion and a second locking portion, the first locking portion having a first end and a second end opposite to the first end, the first end being coupled to one of the seat portion or the frame, the second locking portion being coupled to the other of the seat portion or the frame, the first locking portion being movable between a first position in which the second end is disengaged from the second locking portion so that the seat portion can move relative to the frame, and a second position in which the second end is engaged with the second locking portion so that movement of the seat portion relative to the frame is prevented.

2. The infant swing of claim 1, wherein the first locking portion is pivotally coupled to the frame and movable between the first position and the second position.

3. The infant swing of claim 1, wherein the second locking portion is connected to and extends outward from the seat portion.

4. The infant swing of claim 1, wherein the frame has a lower portion and an upper portion, the support arm is rotatably coupled to the upper portion of the frame, the first locking portion is pivotally coupled to the frame, and the second locking portion is coupled to seat portion.

5. The infant swing of claim 1, wherein the first locking portion slidably engages the second locking portion.

6. The infant swing of claim 1, wherein the first locking portion includes a locking arm with a first end and a second end, the first end of the locking arm being pivotally coupled to the frame and the second end of the locking arm being selectively engageable with the second locking portion.

7. The infant swing of claim 6, wherein the second end of the locking arm includes a pair of resilient arms that are engageable with the second locking portion.

8. The infant swing of claim 6, wherein the locking arm is configured to be placed in a stowed position by engaging the second end of the locking arm with the frame.

9. The infant swing of claim 6, wherein the second locking portion includes a ridge, and the second end of the locking arm includes an indentation that receives the ridge when the locking arm is engaged with the second locking portion.

10. The infant swing of claim 1, wherein the second locking portion includes a first engagement member and a second engagement member, each of the engagement members being coupled to the seat portion, the first locking portion being pivotally coupled to the frame and engageable with the engagement members, the seat portion releasably locked in a first orientation when the first locking portion is engaged with the first engagement member, and the seat portion releasably locked in a second orientation when the second locking portion is engaged with the second engagement member.

11. An infant support structure, comprising:

a frame having a lower portion and an upper portion;

a seat portion rotatably coupled to the upper portion of the frame so that the seat portion is movably coupled to the frame;

an engagement member coupled to the seat portion; and

a lock bar pivotally coupled to the lower portion of the frame, the lock bar movable between a first position disengaged from the engagement member thereby permitting swinging motion of the seat portion, and a second position engaging the engagement member and inhibiting swinging motion of the seat portion.

12. The infant support structure of claim 11, wherein the engagement member is coupled to an underside of the seat portion.

13. The infant support structure of claim 11, wherein the engagement member is a first engagement member, the seat portion includes a second engagement member, the seat portion being releasably locked in a first orientation when the lock bar is engaged with the first engagement member, and the seat portion being releasably locked in a second orientation when the lock bar is engaged with the second engagement member.

14. The infant support structure of claim 11, wherein the lock bar is releasably stowed against the frame.

15. The infant support structure of claim 11, wherein the lock bar comprises arms configured to engage the engagement member.

16. An infant support structure comprising:

a support frame;

a swing arm movably coupled to the frame;

a seat portion coupled to the swing arm;

an engagement portion disposed on one of the seat portion or the support frame; and

a lock bar coupled to the other of the seat portion or the frame, the lock bar being movable between a first position in which the engagement portion receives part of the lock bar and a second portion in which the lock bar is disengaged from the engagement portion, the seat portion being maintained in a fixed position relative to the support frame when the lock bar is in its first position, and the seat portion being movable relative to the support frame when the lock bar is in its second position.

17. The infant support structure of claim 16, wherein the lock bar is pivotally coupled to the support frame and the engagement portion is fixed to the seat portion.

18. The infant support structure of claim 17, wherein the engagement portion slidably receives the lock bar.

19. The infant support structure of claim 16, wherein the lock bar comprises arms that contact the engagement portion when the lock bar is in the first position.

20. The infant support structure of claim 16, wherein the lock bar has a free end that includes a coupling mechanism that captures the support frame.
