Description
- 1. Field of Invention
- The present invention relates to a stroller, and more particularly to a detachable hand bar and foot step arrangement for a stroller wherein a child is able to stand on the foot step or sit on the stroller with different standing or sitting positions respectively.
- 2. Description of Related Arts
- Strollers have been known and sold throughout the United States since stroller becomes a necessity to every family having a young child or baby in which the stroller is considered as a convenience tool to carry the baby or young child during outdoor activities such as jogging or shopping. The conventional stroller contains a foldable structure to reduce its size for storing in the trunk. Referring to FIG. 1 of the drawing, the
conventional stroller 10 comprises afront frame 11 comprising a pair of front supporting posts 111 and aU-shaped handle 112 having two ends respectively connected to two top ends of the pair of front supporting posts 111, aback frame 12 comprising a U-shapedback supporting stem 121 having two ends upwardly extended thereof pivotally connected with thefront frame 11 by means of a pair ofpivot joints 13, a pair offront wheel 14 rotatably mounted on bottom ends of the pair of front supporting posts 111, a pair ofback wheel 15 rotatably mounted on a bottom of theback supporting stem 121, aseat frame 16, which comprises a pair of parallelseat supporting bars 161, mounted between thefront frame 11 and theback frame 12 for supporting a baby to place thereon, and a pair offolding joints 17 for connecting the pair of front supporting posts 111 and the two ends of thehandle 112 together to form therigid front frame 11, wherein by operating thefolding joints 17, thehandle 112 can be folded rearwardly and downwardly towards theback frame 12, so as to fold up thestroller 10 to reduce its size, as shown in FIG. 4. - Usually, a child or baby sits on the seat frame, which faces frontwardly while his or her parent is driving the stroller at its back such that the child may not able to see his or her parent when he or she sits on the stroller. Furthermore, children normally are active that they always like to move around. When they sit on the stroller for a while, they will start trying to move or stand on the seat. However, it is very dangerous because children are soft and weak, if they fall down from the stroller, they may get serious injure. It is quite out of control when the children start yell with their parent while they are being ignored on the stroller. Sometimes, they may just want see their parent's face to get the warm and safe feelings.
- An improved stroller comprises a foot step mounted on the back frame such that the young child is able to stand on the stroller. However, the stroller still has some drawbacks on usage under certain circumstances. For example, U.S. Pat. No. 5,622,375 owned by Fairclough discloses a platform pivotally mounting to rear sloping bars. The front edge of the platform is supported by a pair of straps or springs which are connected between the front corners of the platform and the corresponding bars of the side frame respectively. A pair of rear wheels each having a trailing arm are rotatably mounted to trailing edges of the platform respectively. In such arrangement, the stroller is unstable since the rear wheels are supported by the platform which is merely supported by the straps, the platform will absorb the shock of the stroller while the stroller is being moved. Moreover, the platform may even break since the rear wheels are far from the rear sloping bars, all forces including the child's weight and the partial weight of the stroller will exert on the platform. So, the young child may feel uncomfortable when the platform is shaking or may even get hurt if the platform is insupportably broken.
- A main object of the present invention is to provide a detachable hand bar and foot step arrangement for stroller wherein the stroller is capable of carrying an extra young child in a standing position in the foot step arrangement.
- Another object of the present invention is to provide a detachable hand bar and foot step arrangement for stroller wherein the downward force of the child's weight applied on the foot step arrangement is evenly dispensed to the stroller so as to prevent the platform from any insupportably breaking.
