View Patent ↗A juvenile product adjustment mechanism which allows for easy, secure adjustment by a caregiver is comprised of a rotatable key received within a sliding channel operated by a resiliently biased push button.
1. A juvenile product adjustment mechanism comprising a channel shaped to receive a rotatable key slidingly therethrough, the channel comprising at least two adjustment lobes, wherein each of said adjustment lobes is facing to each other, wherein the key further comprises a boss portion on a back portion thereof, having a width greater than a length thereof, shaped to slide between the adjustment lobes when the length of the boss is positioned parallel to the direction of adjustment of a portion of the juvenile product being adjusted and is prevented from sliding between the adjustment lobes when the length of the boss is positioned transverse to the direction of adjustment of the portion of the juvenile product being adjusted.
2. The juvenile product adjustment mechanism of claim 1 wherein the boss is rectangular shaped.
3. The juvenile product adjustment mechanism of claim 2 wherein the juvenile product being adjusted is a child car seat and the portion of the juvenile product being adjusted is a headrest.
4. The juvenile product adjustment mechanism of claim 3 wherein said headrest includes alignment guides fixedly attached thereto and said car seat includes a base portion, said base portion including alignment channels therein shaped to slidingly receive said alignment guides.
5. The juvenile product adjustment mechanism of claim 1 wherein the rotatable key is operated by means of a push button.
6. The juvenile product adjustment mechanism of claim 5 wherein said push button is resiliently biased.
7. The juvenile product adjustment mechanism of claim 6 wherein said push button is operably connected to said rotatable key by a sliding actuator.
8. The juvenile product adjustment mechanism of claim 7 wherein said sliding actuator includes an attachment leg operably connected to said rotatable key.
9. The juvenile product adjustment mechanism of claim 8 wherein said rotatable key includes a nub on the front portion thereof and said attachment leg includes a follower hole on a portion thereof shaped to operably receive said nub.
10. The juvenile product adjustment mechanism of claim 7 wherein said sliding actuator includes a spring channel therein shaped to receive a spring for resiliently biasing said push button.
11. The juvenile product adjustment mechanism of claim 1 wherein said rotatable key is rotatably mounted on said portion of juvenile product being adjusted by a washer and a fastener.
12. The juvenile product adjustment mechanism of claim 11 wherein said fastener is a screw.
13. The juvenile product adjustment mechanism of claim 1 wherein said adjustment lobes are circular in shape.
14. A juvenile product adjustment mechanism comprising a channel shaped to receive a rotatable key slidingly therethrough, the channel comprising at least two adjustment lobes, wherein each of said adjustment lobes is facing to each other, wherein the key further comprises a boss portion on a back portion thereof, having a width greater than a length thereof, shaped to slide between the adjustment lobes when the length of the boss is positioned parallel to the direction of adjustment of a portion of the juvenile product being adjusted and is prevented from sliding between the adjustment lobes when the length of the boss is positioned transverse to the direction of adjustment of the portion of the juvenile product being adjusted; wherein said rotatable key is operably connected to and rotated by a resiliently biased push button.
15. The juvenile product adjustment mechanism of claim 14 wherein the boss is rectangular shaped.
16. The juvenile product adjustment mechanism of claim 15 wherein the juvenile product being adjusted is a child car seat and the portion of the juvenile product being adjusted is a headrest.
17. The juvenile product adjustment mechanism of claim 16 wherein said push button is operably connected to said rotatable key by a sliding actuator including an attachment leg operably connected to said rotatable key.
18. The juvenile product adjustment mechanism of claim 17 wherein said rotatable key includes a nub on the front portion thereof and said attachment leg includes a follower hole on a portion thereof shaped to operably receive said nub.
19. The juvenile product adjustment mechanism of claim 18 wherein said headrest includes alignment guides fixedly attached thereto and said car seat include a base portion, said base portion including alignment channels therein shaped to slidingly receive said alignment guides.
20. A headrest height adjustment mechanism for a child car seat, said child car seat comprising a headrest and a base portion, said adjustment mechanism comprising a channel on said base portion shaped to receive a rotatable key slidingly therethrough, the channel comprising at least two adjustment lobes, wherein each of said adjustment lobes is facing to each other, wherein the key further comprises a boss portion on a back portion thereof, having a width greater than a length thereof, shaped to slide between the adjustment lobes when the length of the boss is positioned parallel to the direction of adjustment of the headrest and is prevented from sliding between the adjustment lobes when the length of the boss is positioned transverse to the direction of the headrest; wherein said rotatable key is operably connected to and rotated by a resiliently biased push button.
