Description
ATX-PINCH STROLLER FRAME ASSEMBLY
The invention relates to an anti-pinch stroller frame assembly, particularly to an anti-pinch stroller frame assembly having a resiliently biased leg-a}utting block mounted movably on a handle unit and abutting constantly against a rear leg unit of the stroller frame asseuibly A conventional stroller normally includes a handle unit, an armrest unit, and a leg unit adapted to be connected to a wheel unit. The handle unit is pivoted to the armrest unit and includes two opposite side tubes and two spring-biased positioners mounted movably on lower ends of the side tubes, respectively. The leg unit is pivoted to the armrest unit and includes two opposite rear legs that are connected to the positioners through twO interconnecting plates, respectively, so that the handle unit can be positioned to avoid from being rotated relative to the armrest unit, The interconnectingplates engage the positioners in a tongue-and-groove engaging manner, respectively, and can be disengaged from the positioners by moving the p.ositioners upwardly along the side tubes. As a result of the connection between the handle unit and the rear leg unit1 the lower ends of the side tubes are disposed adjacent to the rear legs, and a gap is formed between each of the lower ends of the side tubes and a respective one of the rear legs.
Since the height of the gap may be undesirably reduced due to slightly relative movement between the handle unit and the leg unit during the use of the stroller, child's finger may be accidentally pinched in the gap.
Hence, there is a need to prevent the aforementioned pinching from occurring during strolling.
Therefore, an object of the present invention is to provide an anti-pinch stroller frame assembly that can overcome the aforesaid drawback associated with the
prior art.
According to this invention, there is provided an anti-pinch stroller frame assenibly that comprises: a handle unit having a side tube that has a lower end portion, the lower end portion having a bottom end; a rear leg unit having a rear leg that is adapted to be connected to a wheel and that is connected to the side tube; and aresilientlybiasedleg-abuttingblackmountedmovably on the lower end portion of the side tube, protruding outwardly and downwardly from the bottom end of the lower end portion of the side tube, and abutting constantly and resiliently against the rear leq so as to prevent formation of a gap between the leg-abutting block and the rear leg.
