Abstract

The present invention relates to a lower leg rest adjusting device and an infant carrier therewith for adjusting an angle of a lower leg rest pivoted to a body of an infant carrier. The leg rest adjusting device includes an operating component, a pair of angle-fixing structures and a pair of linking components. Two ends of the lower leg rest adjusting device are pivoted to the body by the pair of angle-fixing structures, and the pair of angle-fixing structures selectively being engaged with the lower leg rest. An end of each linking component is connected to the operating component, the other end of each linking component is connected to the corresponding angle-fixing structure, the operating component driving the pair of linking components to pull the pair of angle-fixing structures to be unlocked from the lower leg rest so as to adjust the angle of the lower leg rest.

First claim

What is claimed is:

1. A lower leg rest adjusting device for adjusting an angle of a lower leg rest pivoted to a body of an infant carrier, the lower leg rest adjusting device comprising:
an operating component;
a pair of angle-fixing structures, two ends of the lower leg rest being pivoted to the body by the pair of angle-fixing structures, and the pair of angle-fixing structures being selectively engaged with the lower leg rest;
a pair of linking components, an end of each linking component being connected to the operating component, the other end of each linking component being connected to the corresponding angle-fixing structure, the operating component driving the pair of linking components to pull the pair of angle-fixing structures to be unlocked from the lower leg rest so as to adjust the angle of the lower leg rest;
a pair of driving components, the operating component being slidably disposed on the lower leg rest, the pair of driving components being disposed on two opposite sides of the operating component respectively, each of the pair of driving components being connected to the corresponding linking component, and the operating component sliding inward with respect to the lower leg rest to drive the pair of driving components to move close to each other, wherein the operating component comprises two first inclined surfaces, each of the pair of driving components comprises a second inclined surface, and the first inclined surfaces and the second inclined surfaces contact against each other; and
an installation holder, the operating component being slidably disposed in the installation holder, an end of the operating component being protruded out of the installation holder, contacting inclined surfaces of the driving components and the operating component being disposed inside the installation holder, and the linking component being disposed inside the lower leg rest;
wherein the operating component comprises an anti-release protrusion, the anti-release protrusion contacting against the installation holder as the operating component slides in a direction far away from the lower leg rest and the anti-release protrusion preventing the operating component from detaching from the installation holder when the anti-release protrusion contacts the installation holder.

2. The lower leg rest adjusting device of claim 1 , wherein a line extending from a sliding direction of the operating component intersects with a line extending from a sliding direction of the driving components.

3. The lower leg rest adjusting device of claim 1 , wherein each angle-fixing structure comprises an engaging component, a first base and a second base engaged with the first base, the first base is connected to the lower leg rest, the second base is connected to the body, a containing chamber is formed by engaging the first base with the second base along a horizontal direction, and the engaging component is contained in the containing chamber.

4. The lower leg rest adjusting device of claim 3 , wherein the first base comprises a first engaging portion stretching into the containing chamber for engaging with a side of the engaging component, the second base comprises a second engaging portion stretching into the containing chamber for engaging with the other side of the engaging component, the second engaging portion is opposite to the first engaging portion, the engaging component is selectively engaged with the first engaging portion, the pair of angle-fixing structures release the lower leg rest when the engaging component detaches from the first engaging component, and the pair of angle-fixing structures fix the lower leg rest when the engaging component engages with the first engaging portion and the second engaging portion.

5. The lower leg rest adjusting device of claim 4 , wherein each angle-fixing structure comprises a pushing component and a resilient component, the pushing component is pivotally contained in the containing chamber and arranged with the engaging component, the resilient component is connected to the engaging component and the second base, the first base further comprises a pushing portion, a withstanding portion is disposed on the pushing component corresponding to the pushing portion, the linking component is connected to the corresponding pushing component, the pushing portion engages with the withstanding portion so that the pushing component drives the engaging component to move toward the second base for detaching from the first engaging portion when the linking component pulls the corresponding pushing component to pivot.

6. The lower leg rest adjusting device of claim 5 , wherein a sheathing portion is disposed in the containing chamber, and the resilient component, the engaging component and the pushing component sheathes the sheathing portion sequentially.

7. The lower leg rest adjusting device of claim 6 , wherein the first base comprises a first sheathing pillar stretching toward the second base into the containing chamber, the second base comprises a second sheathing pillar stretching toward the second base into the containing chamber, and the first sheathing pillar and the second sheathing pillar are connected to form the sheathing portion.

8. The lower leg rest adjusting device of claim 5 , wherein a third inclined surface is formed on the pushing portion, and a fourth inclined surface is formed on the withstanding portion correspondingly for contacting against the third inclined surface.

9. The lower leg rest adjusting device of claim 4 , wherein a plurality of first engaging pieces is protruded out of the first base and spaced annularly to form the first engaging portion, and a plurality of second engaging pieces is protruded out of the second base and spaced annularly to form the second engaging portion.

10. The lower leg rest adjusting device of claim 3 , wherein the second base comprises a stepping locking portion disposed in the containing chamber, the engaging component is slidably installed between the first base and the second base, and the engaging component is selectively engaged with the stepping locking portion.

11. The lower leg rest adjusting device of claim 10 , wherein a line extending from a sliding direction of the engaging component intersects with a line extending from a pivotal axis of the first base and the second base.

12. The lower leg rest adjusting device of claim 11 , wherein the second base comprises at least two locking portions disposed in the containing chamber, and the at least two locking portions are spaced along a pivoting direction of the lower leg rest to form the stepping locking portion.

13. The lower leg rest adjusting device of claim 12 , wherein the engaging component comprises a fastening portion selectively engaged with one of the least two locking portions.

14. The lower leg rest adjusting device of claim 13 , wherein one of the locking portion and the fastening portion is a sunken slot and the other of the locking portion and the fastening portion is a protrusion.

15. The lower leg rest adjusting device of claim 11 , wherein each angle-fixing structure further comprises a resilient component, an end of the resilient component is connected to the engaging component, and the other end of the resilient component is connected to the first base.

16. The lower leg rest adjusting device of claim 11 , wherein each angle-fixing structure further comprises a pivotal shaft, and the pivotal shaft passes through the first base, the engaging component and the second base.
