The support may be configured for selective connection with the track. The support may include a lock plate that may be configured to selectively limit movement of the support relative to the track in at least one of a first direction and a second direction. The support may include an anchor that may be configured to selectively limit movement of the support relative to the track in at least one of the second direction and a third direction. The support may include a cam that may be configured to selectively engage and disengage at least one of the lock plate and the anchor from the track. ## Claims ### Claim 1 A track assembly comprising: a track; and a support configured for selective connection with and movement along the track, the support including: a lock plate configured to selectively engage a lock profile of the track; and a cam connected to the support to rotate about an axis extending in a transverse direction; an anchor configured to selectively engage a ledge of the track; wherein, in a locked position of the lock plate, the lock plate is configured to restrict rotation of the anchor out of a locked position of the anchor; the lock plate includes a pin and the cam includes a recess configured to receive the pin; the pin extends in a transverse direction; a first side of the cam includes the recess; a second side of the cam includes an anchor recess; and the anchor recess is configured to receive a pin of the anchor. ### Claim 2 (depends on 1) The track assembly of claim 1, wherein the cam is configured to selectively engage and disengage the lock plate and the anchor from the track. ### Claim 3 (depends on 2) The track assembly of claim 2, wherein the second side of the cam is disposed opposite the first side of the cam; and the second side further includes a second anchor recess. ### Claim 4 (depends on 1) The track assembly of claim 1, wherein the lock plate includes a recess, and, in an unlocked position of the lock plate, the anchor is configured to rotate into the recess. ### Claim 5 (depends on 1) The track assembly of claim 1, further comprising a second track and a second support configured for selective connection with the second track, wherein the second support includes a second lock plate and a second anchor. ### Claim 6 (depends on 5) The track assembly of claim 5, further comprising a cross member connected to the support and the second support. ### Claim 7 (depends on 6) The track assembly of claim 6, wherein the second support includes a second cam, a first connecting member is connected to the cam and the cross member, and a second connecting member is connected to the second cam and the cross member. ### Claim 8 (depends on 7) The track assembly of claim 7, further comprising a third support configured for selective connection with the track and a fourth support configured for selective connection with the second track, wherein the third support includes a third lock plate, a third anchor, and a third cam, and the fourth support includes a fourth lock plate, a fourth anchor, and a fourth cam. ### Claim 9 (depends on 8) The track assembly of claim 8, further comprising a third connecting member and a fourth connecting member, wherein the third connecting member is connected to the third cam and the cross member, and the fourth connecting member is connected to the fourth cam and the cross member. ### Claim 10 (depends on 9) The track assembly of claim 9, wherein rotation of the cross member causes simultaneous rotation of the cam, the second cam, the third cam, and the fourth cam. ### Claim 11 (depends on 1) The track assembly of claim 1, wherein an initial movement of the lock plate disengages the lock plate from the lock profile; and the initial movement of the lock plate disengages the anchor from the ledge. ### Claim 12 (depends on 11) The track assembly of claim 11, wherein further movement of the lock plate causes rotation of the anchor. ### Claim 13 (depends on 1) The track assembly of claim 1, wherein the second side of the cam includes a second anchor recess, and the second anchor recess is configured to receive a second pin of the anchor. ### Claim 14 (depends on 13) The track assembly of claim 13, wherein the anchor recess includes a first section and a second section, the first section includes a first radius, the second section includes a second radius, and the second radius is smaller than the first radius. ### Claim 15 (depends on 14) The track assembly of claim 14, wherein the anchor is configured to move downward as the cam rotates and the pin of the anchor moves from the first section to the second section. ### Claim 16 (depends on 1) The track assembly of claim 1, wherein the anchor is supported on the support for vertical translation and for rotation about an axis extending in a longitudinal direction; and the lock plate is configured to selectively engage the lock profile of the track from a vertical direction. ### Claim 17 (depends on 1) The track assembly of claim 1, further comprising a wheel connected to the support and configured for rolling along a ridge disposed at a top of the track.
