A rigid structure such as a ladder is disclosed having rotating hinges that allow the ladder to fold up and/or be disassembled and assembled. The hinge or hinges can be provided between ladder sections with one ladder section having a male hinge element, and another having a female hinge element. A cam element provided with the female hinge element can be moved between an unlocked position in which the ladder sections can rotate with respect to each other, and a locked position in which the structure is rigid.

Locking joint for collapsible ladders and other structures

A device for pulling an elongate member includes a rotational motor having an output and a rotating drum connected to the output of said rotational motor. The device further includes a guide mechanism for guiding the resilient elongate element onto, around at least a portion of the circumference of, and off of, the rotating drum. When the rotational motor turns the rotating drum, the rotating drum thereby continuously pulls the resilient elongate element through the device.

Powered rope ascender and portable rope pulling device

A device for pulling an elongate member includes a powered rotational motor having an output and a rotating drum connected to the output of said rotational motor where the rotating drum has a longitudinal axis and a circumference. The device further includes a guide mechanism for guiding the resilient elongate element onto, around at least a portion of the circumference of, and off of, the rotating drum. When the powered rotational motor turns the rotating drum, the rotating drum thereby continuously pulls the resilient elongate element through the device.
