Abstract

The present application provides an armrest rotating mechanism suitable for being installed on an armrest tube and a frame. The armrest tube is rotatably connected to the frame. The armrest rotating mechanism includes an engagement device and an operation device. The engagement device is disposed between the armrest tube and the frame. Via the engagement device, the armrest tube can be positioned relative to the frame. The operation device is disposed on the armrest tube and connected with the engagement device. When the operation device is rotated, the engagement device is driven by the rotated operation device so as to disengage the armrest tube from the frame. Therefore, the armrest tube is adjustable relative to the frame and has a simple structure and utility convenience.

First claim

What is claimed is:

1. A child accommodating apparatus comprising:
a frame;
an armrest tube rotatably connected with the frame; and
an armrest rotating mechanism for rotating the armrest tube, the armrest rotating mechanism comprising:
an engagement device disposed between the armrest tube and the frame and for positioning the armrest tube relative to the frame, the engagement device comprising:
a fixing holder fixed on the frame, a positioning groove being formed on the fixing holder, and the armrest tube being pivoted to the fixing holder; and
an engaging pin configured to engage with or disengage from the positioning groove; and

an operation device disposed on the armrest tube and connected with the engagement device, wherein the operation device is operated to disengage the engaging pin from the positioning groove to disengage the armrest tube from the frame;
wherein the positioning groove comprises an arch portion and two recess portions located at two opposite ends of the arch portion, the engaging pin is located in one of the two recess portions when the engaging pin engages with the positioning groove, and the engaging pin moves from the one of the two recess portions into the arch portion when the engaging pin disengages from the positioning groove, and the engaging pin slides along the arch portion when the armrest tube rotates relative to the frame.

2. The child accommodating apparatus of claim 1 , wherein the engagement device further comprises:
a transmission member connected to the engaging pin and the operation device;
wherein the operation device is operated to drive the transmission member to disengage the engaging pin from the positioning groove.

3. The child accommodating apparatus of claim 2 , wherein the engagement device further comprises:
a sliding member fixed on the engaging pin; and
a resilient member disposed between the armrest tube and the sliding member, the transmission member being connected to the sliding member and the operation device.

4. The child accommodating apparatus of claim 1 , wherein the positioning groove comprises:
a groove portion; and
a plurality of restraining portions positioned at two terminal ends of the groove portion, the engaging pin being configured to move in the groove portion and to be restrained at one of the plurality of restraining portions.

5. The child accommodating apparatus of claim 1 , wherein the engagement device further comprises:
a restoring member installed on the fixing holder, an end of the restoring member abutting against the fixing holder, and another end of the restoring member abutting against the armrest tube.

6. The child accommodating apparatus of claim 2 , wherein the operation device comprises:
a housing rotatably installed on the armrest tube;
a driving groove disposed on the housing; and
an inserting pin engaged with the driving groove and connected with the transmission member.

7. The child accommodating apparatus of claim 6 , wherein an end of the inserting pin abuts against the driving groove, and the driving groove drives the inserting pin and the transmission member when the housing is rotated.

8. The child accommodating apparatus of claim 6 , wherein an extension direction of the driving groove is inclined relative to a horizontal direction, and an extension direction of the inserting pin is substantially perpendicular to a plane whereon the driving groove is located.

9. The child accommodating apparatus of claim 6 , wherein the operation device further comprises:
a button body left and right movably accommodated in the housing and partially exposed outside the housing;
a locking pin connected with the button body; and
a positioning hole positioned on a side of the housing, the locking pin being configured to protrude out of the housing so as to engage with the positioning hole.

10. The child accommodating apparatus of claim 9 , further comprising a leaf spring installed inside the button body.

11. The child accommodating apparatus of claim 2 , wherein the operation device comprises:
a housing fixed on the armrest tube;
a button body up and down movably installed on the housing and the armrest tube; and
an inserting pin selectively engaged with the button body and connected with the transmission member.

12. The child accommodating apparatus of claim 11 , wherein a sliding groove is formed on the armrest tube, and the inserting pin is movably disposed in the sliding groove.

13. The child accommodating apparatus of claim 11 , wherein an inclined surface interfering with the inserting pin is disposed on the button body, a restraining groove is positioned at a terminal end of the inclined surface, and the inserting pin is configured to move along an unlocking direction relative to the inclined surface towards the restraining groove so as to be inserted into the restraining groove for achieving an unlocking status.

14. The child accommodating apparatus of claim 11 , wherein the button body comprises an operation portion exposed outside the housing and for pulling the button body along a locking direction.
