A freestanding companion system with an organizational base, table, connecting, holding and adjusting mechanisms for use beside any seating or reclining furniture is disclosed. The base provides ballast for attachments, including a table, and provides areas for storing desired supplies. The connecting devices and mechanisms allow positioning of a table and other attachments in relation to the base and to the seating/reclining furniture. The table has the following adjustment features: it slides from left to right; it is adjustable closer or further away from the user; it is tiltable, past perpendicular; it swivels/rotates about its vertical support; and it is adjustable in height. Accessories can be added to the freestanding companion system at the base, table, and to the upright supports.

The traveling trolley assembly according to claim 1, wherein the running rail includes a top flange, a bottom flange and a straight web connecting the top flange to the bottom flange. 3. The traveling trolley assembly according to claim 2, wherein the distance between the first side frame bar and the second side frame bar is adjusted by varying the position of the second threaded nut to a desired trolley assembly width corresponding to the width of the bottom flange. 4. The traveling trolley assembly according to claim 1, wherein the first side frame bar is substantially identical to the second side frame bar. 5. The trolley assembly of claim 4 including first and second thread nuts mounted on said threaded rod in opposing relation to each other with at least a portion of said first frame bar therebetween for securing said first frame bar in fixed relation to said threaded nut, and said column. 6. The trolley assembly of claim 5 including third and fourth threaded nuts mounted on said threaded rod in opposing relation to at least a portion of said second frame bar for securing said second frame bar in fixed relation to said threaded rod and to said column. 7. The trolley assembly of claim 6 in which said first frame bar has a wall clamped in predetermined position on said threaded rod between said first and second threaded nuts, and said second frame bar has a wall clamped in predetermined position on said threaded rod between said third and fourth threaded nuts. 8. The traveling trolley assembly according to claim 6, wherein the first threaded nut is adjacent an inner side of the wall of the first side frame bar, the second threaded nut is adjacent an outer side of the wall of the first side frame bar, the third threaded nut is adjacent an outer side of the wall of the second side frame bar, and the fourth threaded nut is adjacent an inner side of the wall of the second side frame bar. 9. The traveling trolley assembly according to claim 6, wherein the third and the fourth threaded nuts are rotated towards each other to lock the first and the second threaded rods in place relative to the second side frame bar. 10. The traveling trolley assembly according to claim 6, wherein the first and the second threaded nuts are rotated towards each other to lock the first and second threaded rods in place relative to the first side frame bar. 11. The traveling trolley assembly of claim 1 in which said threaded rod is disposed at a level below said column. 12. The traveling assembly of claim 11 in which said column has a larger diameter than said threaded rod. 13. The trolley assembly of claim 1 in which said column has a smooth cylindrical surface substantially its entire length, and said first and second frame bars both are selectively positionable over said surface into predetermined spaced relation to each other. 14. The trolley assembly of claim 1 including nuts which are threadably engageable with said threaded rod into predetermined relation to said first and second side bars for securing said side bars in predetermined relation to said threaded rod and hence to said column. 15. The trolley assembly of claim 1 in which said threaded rod is in threaded engagement with at least said first frame bar. 16. The trolley assembly of claim 15 in which said threaded bar is in engagement with both said first and second frame bars. 17. A traveling trolley assembly for hoisting appliances comprising: a first side frame bar spaced a part from a second frame bar; a running rail extending between said frame bars; a first wheel mounted on said first side frame bar and a second wheel mounted on said second side frame bar, said wheels rotating axially parallel to each other; a connecting column extending between said first frame bar and said second frame bar, said extending column being disposed at a location below said first and second wheels and having a longitudinal axis parallel to the axis of rotation of said first and second wheels; said frame bars each being formed with an opening for mounting on said column, said connecting column having a smooth cylindrical outer surface extending substantially the length thereof for permitting selected positioning of at least said first frame bar over said smooth cylindrical surface into predetermined spaced relation to said second frame bar; a threaded rod having a longitudinal axis and being supported between first and second frame bars and having a longitudinal axis parallel to the axis of said column, and said threaded rod being operable for securing the first and second frame bars in predetermined spaced position on said connecting column. 18. The traveling trolley assembly according to claim 17, wherein a traction motor is attached to one of said side frame bars. 19. The traveling trolley assembly according to claim 18, wherein said traction motor includes an output shaft that passes from one of said frame bars to the other side frame bar. 20. The traveling trolley assembly of claim 17 in which said threaded rod is disposed directly below said column. 21. The traveling assembly of claim 17 in which said column has a larger diameter than said threaded rod. 22. The trolley assembly of claim 17 in which said first and second frame bars both are selectively positionable over said column surface into predetermined spaced relation to each other. 23. The trolley assembly of claim 22 including nuts which are threadably engageable with said threaded rod into predetermined relation to said first and second side bars for securing said side bars in predetermined relation to said threaded rod and hence to said column. 24. A traveling trolley assembly for hoisting appliances comprising: a first side frame bar spaced apart from a second frame bar; a running rail extending between said frame bars; pairs of wheels mounted on said first and second frame bars, each pair including a first wheel mounted on said first frame bar and a second wheel mounted on said second frame bar, said pairs of wheels having parallel axes of rotation; a pair of connecting columns extending between said first frame bar and said second frame bar, said extending columns being disposed at a location below said pairs of wheels and having longitudinal axes parallel to the axes of rotation of said pairs of wheels; said first and second frame bars each being formed with an opening for mounting on said columns, said connecting columns each having a smooth cylindrical outer surface extending substantially the length thereof while permitting selective positioning of said first and second frame bars over said smooth cylindrical surface into predetermined spaced relation to each other; a pair of threaded rods each having a longitudinal axis and being supported between said first and second frame bars with the longitudinal axes thereof each being disposed at a level below the longitudinal axis of a respective one of said columns, and said threaded rods being operable for securing the first and second frame bars in predetermined spaced position on said connecting columns. 25. The traveling trolley assembly of claim 24 in which said threaded rods are disposed at a level below said column. 26. The traveling assembly of claim 25 in which said columns have a larger diameter than said threaded rod. 27.
