Abstract: Devices and system for releasably securing objects are disclosed. An insert with tabs around a perimeter is inserted into a receiver. The tabs follow inlet grooves and tab capture grooves, and then retract into tab resting depressions, securing the insert and receiver while force is maintained between the insert and the receiver. The force is removed and the tabs exit the tab resting depressions into the tab release groove. Application of the force again causes the tabs to enter into an outlet groove and out of the receiver, thus detaching the insert and the receiver. The device is preferably used in a system for raising a lowering a rectangular platform with a device at each corner of the platform.

Abstract: A device for moving an object is disclosed. The device has a drive cylinder with drive grooves and a set of idler pulleys. The idler pulleys are on a shaft that is parallel to the drive cylinder. Each of the idler pulleys rotate at an angle around the drive shaft that aligns the grooves of the idler pulleys to neighboring drive grooves. This allows the line to pass onto the drive groove, around an idler pulley, and onto a next adjacent drive groove. The line therefore winds back and forth between the drive grooves, the idler pulleys, and back to the next drive groove. One end of the line is placed under tension and the other is attached to an object or to a fixed member. The drive cylinder is driven and the line is moved through the device, or the device is moved along the line, respectively.
