I've been getting so little done in recent months because I've had a major job on, inventing and designing s suite of 'disappearing' auditorium seats for the RSC in Stratford. Some of these are used when the need to put Production Desks into the auditorium, but most are needed for wheelchair positions - I.e. Seating that can appear or disappear according as to whether it is needed as flat floor to accommodate a wheelchair, or conventional seats.... The problem is that normally this takes significant time and man-power to remove or fit seats, so a better way was needed.
These rubbish videos are of pre-production prototypes. Both units are sunk into the floor, with seats that rise automatically. The first one by swinging up from horizontal to vertical (assisted by rather powerful gas-struts) and the second using electrically powered elevator, containing a pair of seats, sunk into the floor.
Normally, developing these would take the thick end of two years, but we've had four months to do these.
