ACTIFAN DRAWINGS PORTFOLEO JULY 2012 THE BRIDGE HOUSING TRUST PRODUCT DEVELOPMENT DIVISION The following pages describe an automated window operating mechanism which also incorporates a cross flow fan. The purpose of the mechanism is in order to remotely operate the hinging sash of a window, automatically closing the window in rain and opening in the case of fire, whilst exhaust smoke efficiently and quickly with fan assistance. This is a patented concept and mechanism capable of saving lives. The current models Mk1 & Mk11 Actifan are designed for use on vertical fan lights & roof slope windows, where dense smoke can be exhausted from habitable space. A number of companies who will manufacture the other Actifan components have customised their own products to suit our needs. We are now inviting interest from plastic injection moulding companies also capable of metal fabrication to discuss the manufacture of the plastic casing and metal chassis, in order to complete the ring of manufacturers and bring the product to market. The successful applicant/ manufacturer will achieve full rights on the manufacturing of future production models, details to be negotiated following the successful quotation. SHEET 10.

Parts 1,2 & 3 are mild steel welded together and then zinc passivate electro plated; Part 8 spherical plane bearing is then driven into part 2. The crank (part 10) is mild steel. The long arm must be cleaned up, sharp edges rounded off 更多：https://www.bmcx.com/ , swivel face at the long end machined down from 5 to 4mm thick in a 12mm semi-circle; then zinc passivate electro plated; part 9 spherical plane bearing driven into the crank 16mm corner bore, and the finished product powder coated white. The swivel part 12A is machined from stainless steel (or brass); Comprising 3 pieces, the 2 hinge ‘leaves’ and the 4mm hinge pin. No electro plating is required. The rivet and circlip (parts 16 & 18) are also stainless steel for assembly with the long arm of the crank and when installed, the “Igus” slide & carriage, (part 12). The crank pivot pin is stainless steel, and must be a good ‘free to slide’ fit into part 9 (16mm spherical plane bearing). Not an interference fit. We think it advisable to make the casing mould after the fan is fitted to part 3, because the fan makers drawings may not confer perfectly accurate casing dimensions. The folded steel guide slides into position on the base plate between the two base plate rails; The outer rail is the base plate lip pressed into a channel section and the inner rail is stamped into the base plate, parallel. There is some flexibility in the guide’s longitudinal position relative to the base plate when fitted. Its purpose is to restrain any up and down movement of the actuator barrel.
