ABSTRACT:
BACKGROUND OF THE INVENTION
a) Technical Field of the Invention
The present invention relates to dual function baby walker, and in particular, to a baby walker which allow a baby to be seated or to stand and push while walking. The baby walker is suitable for baby at different walking-learning stages.
b) Description of the Prior Art
Conventional baby walkers are generally divided into two types, i.e. a sitting type baby walker and a pushing type baby walker. In the conventional sitting type baby walker, a plurality of wheels are provided to the base of the baby walker and the baby sits on the chair while his legs can touch the ground. This type of baby walker is suitable for baby at the early stage as the baby does not have strong leg muscle to support his body weight. The pushing type of baby walker has a plurality of wheels at the bottom portion thereof and a handle is provided for holding by the baby. However, this type of baby walker suits only baby when the baby is able to stand on his feet.
As these types of baby walkers are for baby at different stage of growth, a consumer has to buy a sitting-type baby walker before the baby is able to walk and at a later stage, the consumer needs to get other pushing-type baby walker when the baby is about to stand on his feet. Therefore, it is not economical to have two baby walkers at the time when the baby is at the early stage of growth.
The present invention intends to provide a dual-function baby walker for assisting baby to walk without getting two separate baby walkers.
SUMMARY OF THE INVENTION
It is the main object of the present invention to provide a dual function baby walker, wherein a supporting frame is mounted at the top of a base seat body which is disposed to the bottom of an upper housing seat including a chamber. When the chamber at the upper housing seat is provided with a chair, the baby can be seated on the chair and the legs of the baby can touch the ground to control the moving direction of the walker. When the baby is standing up, the upper housing seat can be detached from the supporting frame, and the bottom of the upper housing seat is mounted with a plurality of wheel bodies. The top of the upper housing seat is provided with a handle to provide holding for the baby while walking. Thus, the baby walker is suitable to be used for baby at different growth stages such that the baby walker can be functioned as a sitting type of baby walker and a pushing of baby walker as well.
Yet another object of the present invention is to provide a baby walker, characterized in that the upper housing seat is detachable from the supporting frame and the bottom edge of the upper housing seat is mounted with the wheel bodies, and the chamber is disposed with a bag body, the handle being fixed at the top of the upper housing seat.
The foregoing objects and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts. Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
