Patent number: 6244606Abstract: 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.Type: GrantFiled: August 31, 1999Date of Patent: June 12, 2001Inventor: Peng-Yao Yang
