Abstract: A combination desk-step stool furniture piece may provide a portable and/or easy-to-use tool to help children reach elevated objects and have a desk and chair to foster their creative minds or however else they see fit to use it. The piece may include a support frame having a plurality of legs that define a footprint and an upper step and at least one intermediate step. One or more of the steps may lie substantially within the footprint. The upper step and/or the intermediate step may be textured to provide traction to facilitate use of the furniture piece as a step stool. The piece also may include a removable table top that may be attached to the upper step. The frame also may include a storage compartment for stowing the tabletop when the furniture is not being used as a desk. Other embodiments and features also are described.

Abstract: Various electrical connector assemblies are disclosed. The electrical connector assembly can include a pin and a socket. An outer surface of the pin can have an external thread and an annular groove that has an outside diameter that is less than an outside diameter of an adjacent leading flange. The socket can have an internal thread that mates with the external thread on the pin. The connector can comprise independent securing features, such as a threaded connection and a ball detent connection. The connector can be configured such that disengagement of the first connection feature results in disconnection of mating electrical contacts of the pin and socket. In some variants, the second connection feature remains engaged and/or is disengaged independently of the first connection feature.
