Abstract

A changing table is detachably installed on a play yard and capable of weighting a child. The changing table includes a frame, a weighting module and a fabric component. The frame includes a lower frame and an upper frame. The lower frame is detachably installed on the play yard. The upper frame is movably installed on the lower frame. The weighting module comprises four load sensors disposed on four corners of the frame and between the lower frame and the upper frame. The fabric component covers the upper frame to form a supporting area for supporting the child. The changing table can measure a first weight of the child before feeding the child and further measure a second weight of the child after feeding the child, so as to determine a difference of the second weight and the first weight of the child as the feeding intake.

First claim

What is claimed is:

1. A changing table detachably installed on a play yard and capable of weighting a child, the changing table comprising:
a frame comprising:
a lower frame detachably installed on the play yard, the lower frame comprising at least one supporting portion for supporting the changing table on a surface when the changing table is detached from the play yard; and;
an upper frame movably installed on the lower frame;

a weighting module comprising four load sensors disposed on four corners of the frame and between the lower frame and the upper frame; and
a fabric component covering the upper frame to form a supporting area between the upper frame and the lower frame for supporting the child.

2. The changing table of claim 1 , wherein the lower frame further comprises a lower tube, a first lower housing and a second lower housing, the lower tube is under the supporting area, the first lower housing is connected to an end of the lower tube, the second lower housing is connected to the other end of the lower tube, the upper frame comprises a first upper tube, a second upper tube, a first upper housing and a second upper housing, the second upper tube is separated from the first upper tube, the first upper housing is connected to an end of the first upper tube and an end of the second upper tube, the first upper housing is movably installed on the first lower housing, the second upper housing is connected to the other end of the first upper tube and the other end of the second upper tube, the second upper housing is movably installed on the second lower housing, two of the four load sensors are disposed between the first lower housing and the first upper housing, and the other two of the four load sensors are disposed between the second lower housing and the second upper housing.

3. The changing table of claim 1 , wherein the lower frame further comprises at least one mounting portion for mounting on the play yard.

4. The changing table of claim 1 , wherein the weighting module further comprises a display device disposed on the lower frame.

5. The changing table of claim 4 , wherein the weighting module further comprises at least one cable connected to the display device and at least one of the four load sensors.

6. The changing table of claim 5 , wherein the at least one cable passes through the lower frame.

7. The changing table of claim 4 , wherein the display device comprises a monitor, a front cover, a rear cover and a circuit board, the front cover is fixed onto the lower frame, the monitor is installed on the front cover, the rear cover is detachably installed on the lower frame and the front cover, an accommodating space is formed between the front cover and the rear cover, and the circuit board is disposed inside the accommodating space and electrically connected to the monitor and the four load sensors.

8. The changing table of claim 7 , wherein the rear cover comprises at least one latch for engaging with the lower frame.

9. The changing table of claim 7 , wherein the display device further comprises a plurality of buttons and a battery holder, the plurality of buttons are separately installed on the front cover and electrically connected to the circuit board, the battery holder is disposed on the lower frame and away from the accommodating space and electrically connected to the circuit board.

10. The changing table of claim 1 , wherein the four load sensors are fixed on the lower frame by screwing, and two first abutting bosses and two second abutting bosses protrude from the upper frame for abutting against the four load sensors disposed between the upper frame and the lower frame.

11. A play yard assembly comprising:
a play yard; and
a changing table detachably installed on the play yard and capable of weighting a child, the changing table comprising:
a frame comprising:
a lower frame detachably installed on the play yard, the lower frame comprising at least one supporting portion for supporting the changing table on a surface when the changing table is detached from the play yard; and
an upper frame movably installed on the lower frame;

a weighting module comprising four load sensors disposed on four corners of the frame and between the lower frame and the upper frame; and
a fabric component covering the upper frame to form a supporting area between the upper frame and the lower frame for supporting the child.

12. The play yard assembly of claim 11 , wherein the lower frame further comprises a lower tube, a first lower housing and a second lower housing, the lower tube is under the supporting area, the first lower housing is connected to an end of the lower tube, the second lower housing is connected to the other end of the lower tube, the upper frame comprises a first upper tube, a second upper tube, a first upper housing and a second upper housing, the second upper tube is separated from the first upper tube, the first upper housing is connected to an end of the first upper tube and an end of the second upper tube, the first upper housing is movably installed on the first lower housing, the second upper housing is connected to the other end of the first upper tube and the other end of the second upper tube, the second upper housing is movably installed on the second lower housing, two of the four load sensors are disposed between the first lower housing and the first upper housing, and the other two of the four load sensors are disposed between the second lower housing and the second upper housing.

13. The play yard assembly of claim 11 , wherein the lower frame further comprises at least one mounting portion for mounting on the play yard.

14. The play yard assembly of claim 11 , wherein the weighting module further comprises:
a display device disposed on the lower frame; and
at least one cable connected to the display device and at least one of the four load sensors and passing through the lower frame.

15. The play yard assembly of claim 14 , wherein the display device comprises a monitor, a front cover, a rear cover and a circuit board, the front cover is fixed onto the lower frame, the monitor is installed on the front cover, the rear cover is detachably installed on the lower frame and the front cover, an accommodating space is formed between the front cover and the rear cover, and the circuit board is disposed inside the accommodating space and electrically connected to the monitor and the four load sensors.

16. The play yard assembly of claim 15 , wherein the rear cover comprises at least one latch for engaging with the lower frame.

17.
