发明名称 Display tree apparatus
摘要 The present invention provides a support including a central cylindrical body spaced from an upper base and a lower base, each by a gap to provide manual access to a central axial positioned support axle for ease of transport and manipulation of the organization. The central cylindrical body includes an inner cylindrical body, each body including an axially aligned bore for receiving a rod therewithin. A modification of the invention includes a translucent outer cylindrical body, with an illumination member positioned between adjacent outer bores, wherein inner bores of the inner cylindrical body include a pressure-sensitive micro-switch positioned interiorly of the body adjacent the inner bore, whereupon removal of a rod, such as a pencil or lollipop structure from the inner and outer bores closes a circuit to effect actuation of an audible unit.
