Patent attributes
A retract gate has an upper roller assembly, a lower roller assembly, an axial tube, a holding pole, and a screen body. The upper roller assembly has a rolling mechanism and a controlling mechanism. The controlling mechanism has a switch and an engaging component, the engaging component selectively sticking the differential crown gear. Two ends of the axial tube are connected with the upper roller assembly and the lower roller assembly. Two ends of the screen body are securely fixed on the holding pole and the axial tube. When the upper roller assembly is turned on, the rolling mechanism is released; when the upper roller assembly is turned off, the rolling mechanism can memorize the maximum length of the screen body and make the screen body not able to be unrolled further. Consequently, the retract gate can restrict babies and pets within a safe area.
