Abstract: A coupler arm assembly is disclosed which includes a coupler frame with a coupler head and a channel. A hollow housing is defined between the coupler head and the channel. A knuckle is pivotally connected to the coupler head and movable between a coupled position and an uncoupled position. A core pin is received in the hollow housing of the frame. A first end of the pin selectively engages a detent of the knuckle and a second end of the pin extends away from the hollow housing parallel to the channel. The assembly includes two distinct uncoupling devices. The first device includes a solenoid disposed about an outer periphery of the coupler frame. The solenoid applies a magnetic force upon activation to move the pin from engagement with the knuckle. The second device includes a lever arm pivotally connected to the coupler frame adjacent a first end, a plunger adjacent a second end, and an uncoupler armature extending downwardly from the lever arm.

Abstract: Apparatus for automatically uncoupling track-guided toy vehicles includes a first coupling element pivotally mounted on one toy vehicle for pivotal movement between a coupling position and an uncoupling position and a second coupling element mounted on another toy vehicle. The first coupling element couples with the second coupling element when the first coupling element is in a coupling position, and the first coupling element uncouples from the second coupling element when the first coupling element is in an uncoupling position. A spring pivotally biases the first coupling element in the coupling position. A first pivotally suspends a pendulum from the first coupling member.

Abstract: This invention relates to a storage system comprising a rack having at least two opposite walls each wall being provided with several horizontal tracks, one above the other, for permanently applied carriages running along the tracks, the carriages at the first wall cooperating with the carriages at the second wall so that the carriages in pairs serve as a support for a load carrying element extending between the carriages on each horizontal plane possibly with the exception of a lower plane being movable in such a way that it is possible to create a free space above each load carrier element, a hoisting device being movable horizontally above the load carrier elements and vertically in the free space above any of the uncovered carrier elements. Each horizontal track or cooperating pair of tracks has a common drive means by means of which a suitable number of the carriages which are moved along the track or tracks can be moved simultaneously to form the free space.
