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. Each of the step members includes a step main body, and rear and front pivot shafts extending into the step main body. Each of the rear and front pivot shafts has an outer circumferential surface.

A selectively adjustable and lockable utility mount is used to mount a device to a stable structure. The utility mount includes a hydraulic lock that applies the locking force that maintains the locked condition of the utility mount. Mounting brackets for utility mounts have spaced-apart mount elements that engage a surface of a stable structure. Some configurations of mounting bracket include mount elements that are movable between stored conditions and deployed conditions. The stored conditions reduce the size of the device to make it more convenient to pack. A climbing stick uses the storable mount elements.

A hinged ladder for ascending to and descending from a cockpit of an aircraft and method of using the ladder for access to and egress from the cockpit. The ladder is suspended from an anchor which supports the combined weight of the ladder and a user. The ladder comprises a plurality of rung plates connected by hinges. The rung plates have respective holes to accept the foot of a user. In use, the ladder is suspended from an anchor in use, and extends longitudinally. The ladder has a standoff to provide single point contact against a fuselage of the aircraft, preventing damage during use. The standoff may articulate outwardly from a rung plate about an X axis. The standoff may be braced by paired struts which articulate about respective Y axes, preventing collapse of the standoff. Each strut may be locked in position by a respective latch which articulates about a respective Z axis.
