Patent attributes
A bead for releasably securing a glazing unit to a frame member, comprising a body having a first end and a second end, and a resiliently deformable member secured to the body and having a first finger extending from the body to a first end, and a second finger extending from the first finger to a second end. The first end of the body and the first end of the first finger are configured to engage with respective first and second ends of a frame member so as to secure the bead to the frame member. The second end of the body is configured to releasably secure a gasket in a first position so as to secure a glazing unit against an opposed end of the frame member. In use, application of an external force to the gasket moves the gasket to a second position and deflects the second finger from a first position to a second position, and the first finger is configured to separate from the second end of the frame member upon deflection of the second finger to the second position, so as to release the bead from the frame member.
