Abstract: An escape ladder system generally comprising a housing having an inner chamber; a collapsible ladder unit assembly removably received in the housing inner chamber; a cover plate removably coupled to the housing; and, a control unit assembly coupled to the ladder unit assembly. When in its collapsed configuration, the ladder unit assembly is retained by the control unit assembly within the housing inner chamber. The ladder unit assembly is biased for displacement from the housing inner chamber and extension into its extended configuration responsive to appropriate user actuation of the control unit assembly.

Abstract: The subject matter relates to a two-in-one tooth brush unit, comprising a tooth brush and tooth paste, featuring an accommodating hole on the handle of the tooth brush, so the tooth paste can be accommodated in the accommodating hole on the brush handle, while the accommodating hole on the handle and the tooth paste can be wrapped by an adhesive paper label; so configured to achieve functions such as; more convenient packaging process, precludes the unit from being recovered for reuse, disposal of the tooth paste and the tooth brush as one unit, adheres to environmental protection requirements, etc.

Abstract: The subject invention relates to a type of escape ladder structural improvement (1), comprising a housing, an inside ladder, an outside ladder, an outside cover and a gear transmission; the hollow interior of the housing comprising an escape channel; the inside ladder, the outside ladder and the outside cover being respectively installed on the rear and front openings of the hollow interior in the housing; said inside ladder can swing backwards to extend itself by way of its own gravitational weight when a handle is pulled, and via the gear transmission mechanism, it in turn drives the outside cover and the outside ladder to swing forwards to extend themselves, so that the escapee will be able to climb the inside ladder, to the hollow interior of the housing, then to the outside ladder, and escape from the scene by means of the escape device on the outside cover; said mechanism will enable easy operation to create a best escape channel without causing bad effects on the appearance of a building.
