ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a toy stroller, and more particularly, to a foldable toy stroller having a security device for preventing the toy stroller from folding unintentionally. The security device connects the upper frame and the lower frame, and cooperates with a seat mounted to the frame so that the security device cannot be moved to allow the toy stroller to be folded unless the seat is removed from the frame.
BACKGROUND OF THE INVENTION
Generally, a conventional toy stroller is required to be foldable, and this can be achieved by hinges that foldably connect the U-shaped upper frame and the U-shaped lower frame. The upper frame is pivotably connected to two rear frames which have two rear wheels connected thereto, and the lower frame has at least one front wheel connected thereto. A seat with a hood is connected between the two sides of the lower frame. The hinges are designed to be foldable so as to fold the upper frame relative to the lower frame to reduce the space occupied by the toy stroller. Basically, the foldable hinges are equipped with a stop means, which has to be operated before the toy stroller is folded. However, the authorities of most countries require the toy stroller to have a security device to prevent the toy stroller from folding unintentionally so that the manufacturers add various types of security devices to the upper frame or the lower frame. This complicates the structure of the toy stroller and increases the manufacturing cost. In addition, children playing with the toy stroller have to operate the stop means and the security device, and the two procedures could reduce the interest to children.
The present invention intends to provide a toy stroller which has a seat having two engaging members which are mounted to the frame of the stroller and abut the hinges to limit the hinges from being moved so that the frames of the toy stroller will not be folded unintentionally.
The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional foldable toy stroller.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a security device for a foldable toy stroller which has a U-shaped upper frame and a U-shaped lower frame which is pivotally connected to the upper frame by two first hinges, and the rear frame is pivotably connected to the upper frame by two second hinges. The security device comprises two respective bodies each with a first passage to receive one side of the lower frame and a second passage to receive one side of the upper frame. Each of the bodies is located between the first hinge and the second hinge corresponding thereto.
Two engaging members are connected to the seat and mounted to the upper frame, and the two engaging members are respectively located between the body and the second hinge to limit the body's movement.
The object of the present invention is to provide a security device, which connects the upper frame and the lower frame, and is stopped from being disengaged from the lower frame by the engaging members of the seat mounted to the upper frame.
Another object of the present invention is to provide a security device, which can be released to fold the toy stroller by disengaging the seat from the frame of the stroller.
