摘要： A folding staircase for use in a door opening having a threshold. The folding staircase has a pair of stringers that have an upper end and a lower end that is adapted for contacting a ground surface. The stringers are spanned by at least one tread. A hinge is connected to a floor near the door opening and a threshold plate pivotally connected thereto is movable between a use position and a stowed position. The staircase may be provided with a lifting mechanism that biases the staircase and threshold plate toward their stowed positions. The lifting device provides a variable force that provides more rotational force when the staircase would require a user to bear more of its weight and less force when less of the weight of the staircase would be borne by a user.

摘要： A safety ladder for mounting between a support surface and a ground surface includes two support assemblies and parallel step members pivoted between the support assemblies. Each support assembly includes first and second support rods each having upper and lower ends. The upper ends of the first support rods of the support assemblies are configured to be pivoted to the support surface. The safety ladder is movable between a use position, in which the lower ends of the first and second support rods of the support assemblies are adapted to simultaneously contact the ground surface, and a storage position, in which the first and second support rods stand substantially perpendicular relative to the ground surface.

摘要： An access deck assembly is provided for an aerial lift vehicle mobile platform. A base member defines an upper surface to support an operator, and has first and second guides to cooperate with the platform. A locking mechanism is supported by the base member and retains the access deck to the platform. A method of connecting an access deck assembly to a mobile platform is provided. The access deck assembly is positioned relative to the platform to be above and spaced apart from the platform floor surface, with the base member of the access deck assembly substantially within a perimeter frame of the platform. An access deck assembly has a guide member connected to a base member and configured to connect the base member to the mobile platform and support the base member directly above and spaced apart from the platform floor surface.

摘要： 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.

摘要： A self-retractable step for assisting a user in elevating him or herself above a floor, is disclosed. The self-retractable step comprises a self-retractable foot member and a cylindrical assembly coupled with the self-retractable foot member. The foot member is configured to move from one position to another position. The cylindrical assembly comprises a rotary member, one or more spring members and a protuberance member. The rotary member is configured to move the foot member to a predetermined position. Further, the spring members coupled to the rotary member is configured to self-retract the foot member from the predetermined position. The protuberance member disposed at the cylindrical assembly is configured to act as a stopper to hold the foot member in a predetermined position on retraction by the spring members. The self-retractable step further comprises a load bearing member at a base of the foot member.

摘要： A swiveling staircase is provided for access to a device disposed above the ground at a distance that a person of an ordinary height is not able to reach. The staircase includes an immobile upright stanchion and a staircase assembly pivotally coupled to the stanchion. The staircase assembly includes a platform on the top of a plurality of stairs. The staircase assembly rotates between a first position where the staircase is docked out of way for storage and a second position where the staircase assembly is facing the front side of the device so that an operator standing on the platform may be able to reach the device.

摘要： 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.
