Abstract
An interlocking modular support device for a video display or the like is disclosed. The support comprises ring-shaped modules that are identical one with another. The height of the support is adjusted by varying the number of modules employed. The modules are ring-shaped and lock together with a rotary action. The modules also lock to the video display unit they are supporting as well as to a base unit, larger than the modules, to provide a stable base for the assembly.
Claims4
An interlocking support device for a video display unit or the like, said support device comprising:
- one or more generally identical modules;
- each said module having an upper section and a lower section, wherein both the lower section of said module can mate with the upper section of another module and the upper section of said module can mate with the lower section of another module;
- a plurality of leg means within the bounds of said module, protruding from said upper section toward said lower section;
- each said leg means supporting a lip member;
- a plurality of openings through the upper section, corresponding to said leg means;
- each said opening having both a large portion and a smaller portion such that the leg means of a mating module can pass through the large portion of said corresponding opening and upon relative rotation of two mating modules said leg means can enter said respective smaller portions of said openings whereby said lip members prevent the separation of said two modules along a longitudinal direction.
