Telecommunication and electrical service box for mounting in a floor

A telecommunication and electrical service box for mounting into a floor comprising:

• a rigid container having walls and a lid for covering an upper opening in said container, said opening providing access into a cavity defined by said container, said container having access apertures in said walls for receiving service conduits therethrough, said walls including sides, said container adapted for mounting of service outlets in said cavity in service communication with said service conduits,
• at least one recess formed in said sidewalls, said at least one recess having a side opening exposing said at least one recess horizontally outwardly of sides, an elongate first threaded member rotatably and generally vertically mounted within said at least one recess, an operative end of said first threaded member exposed into said cavity so as to be accessible through said upper opening for operative engagement of said head by a user to rotate said first threaded member about its longitudinal axis,
• an elongate cantilevered member threadably mounted at a first end thereof onto said first threaded member, said first threaded member helically threaded so that rotation of said first threaded member in a first direction about said longitudinal axis urges said cantilevered member in upward translation along said first threaded member, said cantilevered member threadably mounted in threaded engagement on said first threaded member so that as said cantilevered member is urged in said upward translation by rotation of said first threaded member in said first direction, said cantilevered member is simultaneously urged to rotate also in said first direction by friction in said threaded engagement,
• a stop formed in said at least one recess for arresting said rotation of said cantilevered member in said first direction when said cantilevered member is in an extended position protruding cantilevered from said at least one recess so as to extend outwardly of said side wall,
• said first threaded member rotatable in a second direction opposite said first direction so as to translate said cantilevered member downwardly and so as to urge, by said threaded engagement, said cantilevered member to rotate also in said second direction into a retracted position nested entirely within said at least one recess, said at least one recess sized to receive said cantilevered member nested entirely therein when in said retracted position.
