Adjustable mechanism for changing floor height of a play yard
View Patent ↗The adjustable mechanism for changing floor height of a play yard according to the present invention comprises at least a foldable frame, a first bed floor, a flexible envelope and an adjustable mechanism. The foldable frame has an upper border portion and a base support assembly. The first bed floor is connected to the base support assembly. The flexible envelope has a second bed floor and a shading periphery connected with the second bed floor, the shading periphery is folded to form an indigitation length exposed outside the foldable frame thereby adjustably hanging on the upper border portion. The adjustable mechanism is operatively mounted on the foldable frame and connected with the lower end of the indigitation length for adjusting the second bed floor relative to the first bed floor in distance and height.
1. An adjustable mechanism for changing floor height of a play yard, comprising:
a foldable frame, having an upper border portion and a base support assembly;
a first bed floor, connected to the base support assembly;
a flexible envelope, having a second bed floor and a shading periphery connected with the second bed floor, the shading periphery being folded to form an indigitation length for adjustably hanging on the upper border portion; and
an adjustable mechanism for adjusting the indigitation length of the flexible envelope, the second bed floor being adjusted relative to the first bed floor in distance and height,
wherein the first bed floor has at least a vertical flap connected to the shading periphery for forming a storing space between the first bed floor and the second bed floor.
2. The adjustable mechanism for changing a floor height of a play yard of claim 1 , wherein the foldable frame includes a plurality of vertical struts pivoted with the upper border portion and the base support assembly that permits the foldable frame to be kept in an erected position and a folded position.
3. The adjustable mechanism for changing floor height of a play yard of claim 1 , wherein the first bed floor has a plurality of vertical flaps connected to the second bed floor for forming a plurality of storing spaces between the first bed floor and the second bed floor.
4. The adjustable mechanism for changing floor height of a play yard of claim 1 , wherein the flexible envelope includes a pad for paving on the second bed floor.
5. The adjustable mechanism for changing floor height of a play yard of claim 4 , wherein the pad is foldable.
6. The adjustable mechanism for changing floor height of a play yard of claim 2 , wherein the plurality of vertical struts each has a plurality of positioning portions for keeping the adjustable mechanism in a selected position, thereby fixing the second bed floor at a height.
7. The adjustable mechanism for changing floor height of a play yard of claim 6 , wherein the adjustable mechanism further comprises:
a sliding carrier connected with a corner of the flexible envelope and capable of moving along the plurality of vertical struts, thereby adjusting the indigitation length and the second bed floor;
a spring-biased locking element operatively connected with the sliding carrier for engaging with one of the plurality of positioning portions; and
a release actuator associated with the spring-biased locking element for disengaging the spring-biased locking element from the positioning portions.
8. The adjustable mechanism for changing floor height of a play yard of claim 7 , wherein the spring-biased locking element has a slanting end face that permits the sliding carrier to move downward without manipulating the release actuator.
9. The adjustable mechanism for changing floor height of a play yard of claim 6 , wherein the flexible envelope has a plurality of pulling elements for pulling the indigitation length downward, thereby lifting the second bed floor upward.
10. The adjustable mechanism for changing floor height of a play yard of claim 7 , wherein each of the plurality of vertical struts is formed with a guiding slot for guiding the sliding carrier.
11. The adjustable mechanism for changing floor height of a play yard of claim 10 , wherein the plurality of positioning portions include a plurality of holes formed within the guiding slot for engaging with the spring-biased locking element.
12. The adjustable mechanism for changing floor height of a play yard of claim 7 , wherein the release actuator includes a button for driving the spring-biased locking element.
13. The adjustable mechanism for changing floor height of a play yard of claim 7 , wherein the release actuator is retractably received in the sliding carrier and biased by a resilient element.
14. The adjustable mechanism for changing floor height of a play yard of claim 7 , wherein the spring-biased locking element is biased toward the positioning portions by a resilient element.
