CA 2384732

A resilient, insulated door panel (21) for a sliding door includes a resilient core (32) protected by a compliant outer covering (40) with a seal (50, 52) disposed about the perimeter of the panel. The panel (21) has sufficient resilience to recover from an impact that temporarily deforms it, yet has sufficient rigidity to transmit a compressive force needed for effectively setting the seals. Much of the core (32) is filled with air to not only provide effective insulation and resilience, but to also provide an extremely light-weight door panel that can be operated to travel rapidly along an overhead track. Some embodiments include relatively rigid backup plates (36) that provide a solid foundation to which the perimeter seals (50, 52) can be attached. The backup plates (36) are segmented so as not to completely restrict the flexibility of the door panel (21).

L'invention concerne un panneau (21) de porte isolé et résilient pour porte coulissante, comprenant une partie centrale (32) résiliente protégée par un revêtement (40) extérieur souple, un joint (50, 52) étant disposé sur tout le pourtour extérieur du panneau. Ledit panneau (21) est non seulement suffisamment résilient pour reprendre sa forme à la suite d'un impact l'ayant temporairement déformé, mais également suffisamment rigide pour transmettre la force de compression nécessaire à la solidarisation efficace des joints. Une partie non négligeable de la partie centrale (32) est remplie d'air non seulement pour assurer une isolation et une résilience efficace, mais aussi pour constituer un panneau de porte extrêmement léger que l'on peut rapidement faire coulisser le long d'un rail suspendu. Selon certains modes de réalisation, le panneau comprend des plaques (36) d'appui relativement rigides formant une base solide sur laquelle les joints périphériques (50, 52) peuvent être fixés. Ces plaques (36) d'appui sont segmentées de manière à ne pas restreindre complètement la flexibilité du panneau (21) de porte.
