A building having a security and safety function of the present invention may include: a house body that is configured to include an inner panel that defines an interior space, an outer panel that surrounds the inner panel to be spaced a predetermined distance from the outer surface of the inner panel, a heat insulating material that is installed between the inner panel and the outer panel, and an air flow passage that is formed between the inner panel and the outer panel to facilitate a fluid flow therebetween and to block the heat transfer with respect to the outside; an indoor entrance door configured to be installed on one side of the house body for entering the interior space; and an outdoor entrance door configured to be installed on the house body in front of the indoor entrance door. The building can control the entry of children or outsides into the rooftop of the building without permission from the user in order to thereby prevent safety accidents and in order to thereby improve a security function.

A ladder assembly is described. The ladder assembly includes a frame, a door, a ladder and a cord manipulation assembly. The frame at least partially surrounds a first opening. The door is movably connected to the frame. The door is configured to cover at least a portion of the first opening of the frame, the door defines a second opening. The ladder is connected to at least one of the frame and the door. The ladder has a first side rail, a second side rail spaced a distance apart laterally from the first side rail, and a plurality of rungs extending between the first and second side rails. The ladder is configured to be at least partially positioned within the first opening of the frame. The cord manipulation assembly is connected to the door. The cord manipulation assembly has a power source connector, a reel adapted to support a cord, a motor operatively connected to the reel and the power source connector, and a remote control transceiver assembly operatively connected to the motor and the power source connector.

A roofing ladder bracket and safety assembly adapted to be secured to a roof of a building comprising a base member and a clamping member configured as a ladder clamping mechanism for firmly securing a ladder to a roof of a building and including a safety mechanism to which a worker's safety equipment or a worker's tethered tool can be attached.

A foldable step system includes a cabinet that has a door. A step unit is hingedly coupled to the door. The step unit is positioned in a deployed position when the door is positioned in an open position. Thus, the step unit may support a user thereby facilitating the user to reach an elevated object. The step unit is positioned in a stored position such that the door may be positioned in a closed position. A drive is movably coupled to the step unit such that the drive selectively positions the step unit in the deployed position.

A ladder assembly is described. The ladder assembly includes a frame, a door, a ladder and a cord manipulation assembly. The frame at least partially surrounds a first opening. The door is movably connected to the frame. The door is configured to cover at least a portion of the first opening of the frame, the door defines a second opening. The ladder is connected to at least one of the frame and the door. The ladder has a first side rail, a second side rail spaced a distance apart laterally from the first side rail, and a plurality of rungs extending between the first and second side rails. The ladder is configured to be at least partially positioned within the first opening of the frame. The cord manipulation assembly is positioned between a pair of adjacently disposed rungs of the ladder. The cord manipulation assembly has a power source connector, a reel adapted to support a cord, a motor operatively connected to the reel and the power source connector, and a remote control transceiver assembly operatively connected to the motor and the power source connector.

A system is provided for safe access to a roof through an opening in a roof of a structure having a fixed ladder leading upward to the opening. The system includes a mechanism to drive a set of pushrods to raise a hatch covering the opening. The system may include a section of ladder secured to the underside of the hatch. The system may have an extendable ladder driven by the drive mechanism to slide along the fixed ladder and extend through the opening in the roof when the hatch is raised. The system may include a safety pole driven by the drive mechanism to extend through the opening in the roof when the hatch is raised. The system allows someone who needs to access the roof for inspection or maintenance to safely open the hatch, climb up through the opening in the roof, and safely step onto the roof.
