Description of the Preferred Embodiment Now referring to Fig. 2, the safe folding device according to one embodiment of the present invention will be described in detail.
As shown in Fig. 2, the safe folding device according to the present invention comprises: a pair of folding mechanisms (210) having a button (212), which are provided at right and left sides of a foldable stroller respectively; a base plate (220) for
<Desc/Clms Page number 3>
a baby seat (230), provided below a baby seat (230) and having a protuberance (222) at both sides respectively ; and an operation rope (224), fixed on one surface of the base plate (220).
The folding mechanism (210) is a general folding mechanism which is popularly used in an ordinary foldable stroller, wherein the foldable stroller is fully stretched in the first engaged status (unshown in the figures) and the foldable stroller is collapsed for storage or carriage in the second engaged status (unshown in the figures). Of course, the folding mechanism (210) could be designed to have more than two engaged statuses if necessary. Since the design of the folding mechanism (210) is not major feature of the present invention, the detailed description of the folding mechanism (210) is omitted. The button (212) is a switch button of the folding mechanism (210) for switching the first engaged status and the second engaged status of the folding mechanism (210), which is used to release the engaged status of the folding mechanism (210). When the button (212) is pressed downward, the foldable stroller can be collapsed for storage. Usually, the button (212) cooperates with a spring or the like (unshown in the figures). When an external forced is applied, the button (212) would be pressed downward. Once the external force disappears, the button (212) would be returned to its normal (original) position due to the recovery force produced by the spring. Similarly, the design of the button (212) is not major feature of the present invention, the detailed description of the button (212) is omitted.
The baby seat (230) is used for receiving or accommodating a baby. Below the baby seat (230), there is provided a base plate (220) for supporting the baby seat (230).
According to the safe folding device of one embodiment of the present invention, two corresponding protuberances (222) are provided at both sides of the base plate (220) respective, as shown in Fig. 2. The function of the protuberances (222) is to contact and press down the button (212) to release the engaged status of the folding mechanism (210) (described later). According to the safe folding device of one embodiment of the present invention, an operation rope (224) is provided on one surface of the base plate (220), wherein two ends of the operation rope (224) are fixed on the base plate (220), as shown in Fig. 2. When a user intends to collapse the foldable stroller, all he or she has to do is to pull the operation rope (224) upward by one single hand to bring the base plate (220) upward so that the protuberances (222) contact and then press downward the button (212) of the folding mechanism (210) to release the engaged status of the folding mechanism (210) to collapse the foldable stroller Referring to Figs. 4-6, the operation status of the safe folding device according to one embodiment of the present invention is explained as follows.
Fig. 4 is a view, showing the status of the safe folding device shown in Fig. 3
<Desc/Clms Page number 4>
when the foldable stroller is not collapsed, i. e. the situation where the foldable stroller is in normal use (not collapsed) Fig. 5 is a view, showing the status of the safe folding device shown in Fig. 3 when a user pulls the operation rope (224) upward to the extent that the protuberances (222) of the base plate (220) just contact the button (212) of the folding mechanism (210). Fig. 6 is a view, showing the status of the safe folding device shown in Fig. 3 when a user pulls the operation rope (224) upward completely so that the protuberances (222) of the base plate (220) press down the button (212) of the folding mechanism (210) to release the engaged status of the folding mechanism (210) to collapse the foldable stroller As shown in Figs. 4-6, when a user intends to collapse the foldable stroller, all he or she has to do is to pull the operation rope (224) upward by one single hand to bring the base plate (220) upward so that the protuberances (222) contact and then press downward the button (212) of the folding mechanism (210) to release the engaged status of the folding mechanism (210) to collapse the foldable stroller According to another aspect of the present invention, there is provided a limiting groove (223) on the protuberance (222), as shown in Fig. 3 The limiting groove (223) cooperates with a limiting pin (213) for directing the moving direction of the protuberances (222) and limiting the moving distance thereof so as to make sure the protuberances (222) can precisely and correctly contact and press down the button (212) of the folding mechanism (210) to avoid the improper operation due to a user over draws the operation rope (224).
Though the button (212) is provided at the inner side of the folding mechanism (210) in Fig. 3, the button (212) may be provided at the lower side of the folding mechanism (210) if necessary in a special design as long as the button (212) can cooperate with the design of protuberance (222) to achieve the effect of collapsing a foldable stroller by the operation rope (224). Similarly, the button (222) can be designed in various manners once if the action of pressing down the button (222) can release the engaged status of the folding mechanism (210) The safe folding device for a foldable stroller according to the present invention has many merits, for example, a use can release the engaged status of a folding mechanism with only one single hand by means of using an operation rope so that a foldable stroller can be collapsed in a simple and convenient way. Besides, since the operation rope is mounted on the base plate below the baby seat, a user can not collapse the foldable stroller when a baby is in the foldable stroller. Therefore, danger incidentally caused by improper operation of a foldable stroller can be effectively avoided.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details
