Abstract
A fixing safety-control device for a collapsible child walker is composed by a pressing article and an integral stopping board. On one reinforcing rib near the end of the sliding groove in the base member is provided with a crooked groove. The inserting strip provided on one end of the stopping board is inserted into the crooked groove to be fixed, and then the pressing article is penetrated through the sliding groove of the base member to let the front head be inserted into the hole of the stopping board so as to be in a fixed position. When the seat structure being collapsed, the sliding article of the connection structure will be stopped against the stopping surface of the stopping board and fixed so as to keep a safe distance from the base member to prevent a user's hands from being clamped. At last, the pressing article is pressed to let the stopping board separate from the sliding article, and by the elasticity of the hook, the child walker can be collapsed successfully and safely.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a fixing safety-control device for a collapsible child walker, which is provided with a pressing article and a stopping board to fix the seat structure in a certain height, and more particularly to the fixing safety-control device with innovative features which can let the seat structure keep a safe distance from the base member so as to prevent a user's hands from being clamped when a child walker being collapsed.




2. Description of the Related Art




Referring to

FIG. 1

, a conventional child walker is generally composed by a base member


10


, a connection structure


20


and a seat structure


30


. When being collapsed, the catch board


301


of the seat structure


30


is pressed to make the catch portion


302


separate from the ratchet


303


, as shown in

FIGS. 2 and 3

, so as to make the sliding article


201


of the connection structure


20


be forced to slide along the sliding groove


101


of the base member


10


so that the seat structure


30


will rapidly fall down to rest against the base member


10


. Because of no safety-control device, when the seat structure


30


being forced to fall down, a user's hands are often clamped and hurt, as shown in FIG.

SUMMARY OF THE INVENTION




Therefore, the present invention is directed to a fixing safety-control device for a collapsible child walker that substantially obviates the drawback of the related conventional art.




An object of the present invention is to provide a fixing safety-control device which can fix the sliding article of the connection structure against the stopping surface of the stopping board when the seat structure of a child walker being collapsed.




Another object of the present invention is to provide a fixing safety-control device which can fix the seat structure in a certain height to keep a safe distance from the base member so as to prevent a user's hands from being clamped when a child walker being collapsed.




Yet another object of the present invention is to provide a fixing safety-control device whose pressing article can be pressed to make the stopping board separate from the sliding article to let a child walker be collapsed safely and successfully.




Accordingly, to achieve these advantages, a fixing safety-control device for a collapsible child walker in the present invention is composed by a pressing article and an integral stopping board. On a proper section of one reinforcing rib in the bottom of the base member is provided with a crooked groove. The inserting strip provided on one end of the stopping board is inserted into the crooked groove to be fixed, and then the pressing article is penetrated through the sliding groove of the base member to let the front head be inserted into the hole of the stopping board so as to be in a fixed position. When the seat structure being collapsed, the sliding article of the connection structure will be stopped against the stopping surface of the stopping board and fixed so as to keep a safe distance from the base member to prevent a user's hands from being clamped. At last, the pressing article is pressed to let the stopping board separate from the sliding article, and by the elasticity of the hook, the child walker can be collapsed successfully and safely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




A preferred embodiment of a collapsible child walker includes a base member


10


, a connection structure


20


, a seat structure


30


and two fixing safety-control devices


40


. The fixing safety-control devices


40


in the present invention are respectively provided to control both sliding articles


201


of the connection structure


20


in the base member


10


.




Each fixing safety-control device is composed by a pressing article


401


and an integral stopping board


402


, as shown in FIG.


5


. Each pressing article


401


is provided with a front head


4011


of barbs. On one end of each stopping board


402


is provided with an inserting strip


4021


, a hole


4022


is provided in the central section of each stopping board


402


, and the other end of each stopping board


402


is provided with a stopping surface


4023


and a hook


4024


.




Referring to

FIG. 6

, on one reinforcing rib


103


A near the end of each sliding groove


101


in the base member


10


is provided with a crooked groove


102


for each inserting strip


4021


provided on one end of each stopping board


402


to be inserted in and fixed. Each pressing article


401


is penetrated through each sliding groove


101


in the base member


10


to let each front head


4011


with barbs be inserted into the hole


4022


of each stopping board


402


so as to be caught and fixed.




When the seat structure


30


of the child walker being collapsed, the catch board


301


of the seat structure


30


is pressed to make the catch portion


302


separate from the ratchet


303


, as shown in FIG.


2


. When each sliding article


201


of the connection structure


20


sliding along each sliding groove


101


in the base member


10


, each sliding article


201


will be forced to stop against each stopping surface


4023


of each stopping board


402


, as shown in FIG.


6


. At the same time, the seat structure


30


will be kept a safe distance from the base member


10


, as shown in

FIG. 7

, so as to prevent from clamping a user's hands. At last, each pressing article


401


is pressed to let each stopping board


402


separate from each sliding article


201


, as shown in

FIG. 8

, and each hook


4024


provided at the other end of each stopping board


402


will properly stop against one central post


103


B. By the elasticity of ache hook


4024


, the child walker can be collapsed successfully and safely.




While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications which may fall within the spirit and scope of the invention.
