DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1-11 illustrate a preferred embodiment according to the invention, this embodiment provides a multifunctional baby walker which has three working statuses: a conventional walker status, wherein a baby sits in the baby walker and her/his feet can touch the ground; a stroller status, wherein a baby can try to stand up and walk with help; and a riding status. The configuration of the baby walker of the invention will be further illustrated in more detail with reference to accompanying drawings.

As shown FIGS. 1 to 11, the baby walker comprises a tray frame 1 located at an upper portion of the baby walker, a chassis frame 2 located at a lower portion of the baby walker, a supporting frame 3 connected between the tray frame 1 and the chassis frame 2, multiple roller wheels 4 disposed at bottom of the chassis frame 2, as well as a seat pocket assembly 5. The chassis frame 2 comprises two symmetrical side brackets 20 at two sides of the baby walker and a front bracket 24 for connecting front ends of the two side brackets 20. The lower portion of the supporting frame 3 substantially is fixedly connected to the middle of the front bracket 21.

The supporting frame 3 further comprises a lower bracket 30 with a lower portion being fixedly connected to the front bracket 21, an upper bracket 31 with a lower end being inserted into the lower bracket 30, and between the lower bracket 30 and the upper bracket 31 a positioning mechanism is disposed for fixing them to each other. In this embodiment, the positioning mechanism comprises a button 70 disposed on the lower end of the upper bracket 31 and a positioning hole 71 opened on a side wall of the lower bracket 30, the upper bracket 31 is fixed relative to the lower bracket 30 when the button 70 is inserted into the positioning hole 71, in this case the supporting frame 3 is in a first height, as shown in FIG. 3. When it is desired to increase the height of the supporting frame 30, the button 70 is pressed and detached from the positioning hole 71, and then the upper bracket 31 is pulled up to reach a second height, as shown in FIG. 2. Furthermore, the supporting frame 3 also has an accommodating space 3a having a backwards opening, and is provide with a handle 3b for holding at an upper portion thereof.

The seat pocket assembly 5 comprises an arc front support rod 50 with a lower end being rotatably connected to the front bracket 21, a seat pocket 51 and arc rear support rods 52 at two sides of the baby walker. As shown in FIGS. 7 and 8, the seat pocket 51 can slide along the extending direction of the front support rod 50, this design is advantageous, particularly when the seat pocket 51 and the front support rod 50 are not in use, firstly the seat pocket 51 slides along the front support rod 50 so that the whole volume of them is smaller, and then the seat pocket 51 and the front support rod 50 are rotated relative to the front bracket 21 such that they are accommodated within the accommodating space 3a of the supporting frame 3. The rear support rods 52 have three statuses: in a first status, the rear support rods 52 support the seat pocket 50 together with the front support rod 51, so that the baby walker is in a riding status, as shown FIG. 5; in a second status, the rear support rods 52 support the tray frame 1 together with the supporting frame 3, so that the baby walker is in a conventional walker status, as shown FIG. 1; and in a third status, the rear support rods 52 are received within the housing space 20a at an inner side of the side brackets 20 so that the baby walker is in a stroller status as shown in FIG. 9. Specifically, the front ends of the rear support rods 52 are detachably connected to the rear portion of the seat pocket 51, and the front ends of the rear support rods 52 are also detachably connected to the tray frame 1, and the rear ends of the rear support rods 52 are connected to the side brackets 20 by connection sleeves 6. Preferably, a connecting sleeve 6 is rotatably connected to the inner side of a side bracket 20 by a first rotation shaft 6a extending horizontally, and a rear end of a rear support rod 52 is rotatably connected to the connecting sleeve 6 by a second rotation shaft 6b which is perpendicular to first rotation shaft 6a, thus, the front ends of the rear support rods 52 can move upwards and towards the middle relative to the side brackets 20, and thus the baby walker can be converted during the three statuses. By means of the above connection means, the rear support rods 52 can be adjusted freely in a wide angle range.

As described above, the height of the supporting frame 3 is adjustable. A plurality of joints 10, 11 are provided at bottom of the tray frame 1 along an anterior-posterior direction so that the tray frame 1 is adapted to connected with the rear support rods 52 in different heights. For example, the front ends of the rear support rods 52 are connected with the tray frame 1 by joints 11 when the baby walker is in a height shown in FIG. 2, and the front ends of the rear support rods 52 are connected with the tray frame 1 by joints 10 when the baby walker is in a height shown in FIG. 3.

In conclusion, the baby walker of this embodiment of the invention has the following advantages:

1. The baby walker of the invention has multiple functions, it can server as a conventional walker, a stroller for pushing or a carriage for riding, thus, it can help a baby learn to walk and can be adapted to children in a wider range of ages. Furthermore, the baby walker is adjustable in height when it is used as a conventional baby walker or a stroller, thus, expected effects can be achieved for the children or babies in different heights.

2. The baby walker is designed ingeniously and simple in configuration, and no any other parts are added comparing the existing single-functional baby walkers.

3. The baby walker can be converted conveniently and optionally during the three statuses.

The invention is illustrated detailedly as above, however it is to be noted, that the aim is intended to enable a person skilled in the art to appreciate the content of the invention and further implement it, and the protecting scope of the invention can not be limited hereby. Also, any equivalent variations or modifications made according to the spirit of the invention should be covered within the protecting scope of the invention.
