COMBINED STRUCTURAL BODY MADE OF RIGID MEMBERS PROVIDED WITH COUPLING ELASTIC MEMBERS

摘要

A structure, of strip form for example a composite insulated member used as part of a door frame, comprises parallel outer metallic parts (1) and an intermediate, connecting resilient body (3). The intermediate body, at each side confronting a metallic part, is of a C-shaped cross-section with the free limbs (6, 7) of the C designed to fit between opposed ribs (17, 18) on the associated metal part. The free limbs of the C have projections (14, 15) for snap-in engagement in longitudinal recesses (19, 20) in the corresponding ribs. Adhesive (5) to fix the ends (12, 13) of the ribs or plastics material to foam and fill the cavity may be provided in the channel (4). IMAGE
