Three wheels support the rolling base, each leg having one wheel each with the third wheel secured to the hinge mechanism. Two attachments are provided, one at the hinge with a second positioned between the legs. The attachment mechanisms accepting support members used to support lights, cameras, and other accessories. ## Claims ### Claim 1 A base comprising: a) A first leg and a second leg, said first leg and the second leg secured to each other at their second ends via a hinge mechanism; b) A first wheel secured to the first end of the first leg; c) A second wheel secured to the first end of the second leg; d) A third wheel secured to the hinge mechanism; e) A first attachment receptacle secured proximate to the hinge mechanism; f) An arm mechanism extending from the hinge mechanism between the first leg and the second leg; and, g) A second attachment receptacle positioned at an end of the arm mechanism. ### Claim 2 (depends on 1) The base according to claim 1, wherein the first leg and the second leg are selectively elongated. ### Claim 3 (depends on 2) The base according to claim 2, further including a limiting mechanism positioned proximate to the hinge mechanism, said limiting mechanism establishing a maximum angle between the first leg and the second leg. ### Claim 4 (depends on 3) The base according to claim 3, wherein the maximum angle is fifty six degrees. ### Claim 5 (depends on 2) The base according to claim 2, further including a first support, a proximal end thereof configured to be accepted by either the first attachment mechanism or the second attachment mechanism. ### Claim 6 (depends on 5) The base according to claim 5, wherein the first support is adjustable in length and wherein a distal end of the first support mechanism is configured to be secured to an accessory. ### Claim 7 (depends on 6) The base according to claim 6, further including a second support, a proximal end thereof configured to be accepted by either the first attachment mechanism or the second attachment mechanism. ### Claim 8 (depends on 7) The base according to claim 7, further including a beam adapted to be secured a distal end of the first support and a distal end of the second support such that an end of the boom extends past the second end of the first leg and the second end of the second leg. ### Claim 9 (depends on 5) The base according to claim 5, wherein the first leg includes a first bracket secured proximal to the second end of the first leg. ### Claim 10 (depends on 9) The base according to claim 9, wherein the second leg includes a second bracket secured proximal to the second end of the first leg. ### Claim 11 A base comprising: a) A first leg and a second leg, said first leg and the second leg secured to each other at their second ends via a hinge mechanism, said first leg, second leg, and hinge mechanism on rollers; b) A first attachment receptacle secured proximate to the hinge mechanism; c) An arm mechanism extending from the hinge mechanism between the first leg and the second leg; and, d) A second attachment mechanism positioned at an end of the arm mechanism. ### Claim 12 (depends on 11) The base according to claim 11, further including a first support, a proximal end thereof configured to be accepted by either the first attachment mechanism or the second attachment mechanism, said first support being adjustable in length, a distal end of the first support configured to be secured to an accessory. ### Claim 13 (depends on 12) The base according to claim 12, further including a second support, a proximal end thereof configured to be accepted by either the first attachment mechanism or the second attachment mechanism, said second support being adjustable in length, a distal end of the second support configured to be secured to an accessory. ### Claim 14 A base comprising: a) A first leg and a second leg, said first leg and the second leg secured to each other at their second ends via a hinge mechanism allowing the first leg and second leg to collapse next to each other; b) A first wheel secured to the first end of the first leg, a second wheel secured to the first end of the second leg, and a third wheel secured to the hinge mechanism; c) A first attachment receptacle secured proximate to the hinge mechanism, and a second attachment mechanism positioned using an arm suspended by the hinge mechanism, between the first leg and the second leg. ### Claim 15 (depends on 14) The base according to claim 14, further including a limiting mechanism positioned proximate to the hinge mechanism, said limiting mechanism establishing a maximum angle between the first leg and the second leg. ### Claim 16 (depends on 15) The base according to claim 15, wherein the limiting mechanism provides support for the arm mechanism. ### Claim 17 (depends on 16) The base according to claim 16, wherein the arm mechanism is moveable relative to the first and second leg.
