A screen system which can be easily disassembled and includes a screen, a frame supporting the screen where the frame includes a hook, and a housing supporting the frame. The housing defines a retainer which interacts with the hook whereby upon rotation of the frame in a first direction the hook engages the retainer and upon rotation of the frame in a second direction the hook disengages the retainer allowing disassembly of the screen system. The screen system may be part of a ventilation system.

Screen system allowing easy disassembly

An exhaust vent including a roof cap inlet and a roof cap outlet which are joined together without the use of fasteners and which defines a vent for use in venting gases from the inside of a building structure. The roof cap inlet includes a base portion defining an aperture and including a cylindrical extension extending below the base portion for attachment to a duct, and a rectangular extension extending above the base portion for preventing ingestion of water through the aperture. The roof cap outlet is formed with a semicircular portion defining a flow passage and includes a hemispherical portion defining a closed end for the flow passage wherein the design of the roof cap outlet provides increased strength against deformation, and the hemispherical and semicircular shape of the roof cap outlet facilitates flow of gases through the exhaust vent to the outlet opening.

An exhaust fan for bathrooms and the like having two principal structural elements--a housing assembly and a motor plate assembly--wherein the housing assembly includes a generally cylindrical housing formed of injection molded plastic. The housing assembly includes a circumferential mounting flange and mounting clips carried thereon for mounting the fan in a ceiling panel or the like in an arbitrary angular orientation. Flexible mounting tabs on the motor plate assembly releasably engage notches on the housing for snap together assembly. Integral strain relief for power supply wiring is molded into a wiring compartment in the housing. An oval duct connector having an outer circumferential lip extends from an exhaust outlet and is adapted to releasably engage a round flexibly resilient spring reinforced duct thereover. The motor plate assembly also covers the wiring compartment when fitted into the housing assembly.
