PLASTIC TAMBOUR DOOR

Tambour or roll up door is made by vacuum forming a heated thin plastic sheet into a form wherein the front face of the door comprises a series of relatively wide parallel face strips which are joined to each other by integral thin connecting portions having a generally U-shaped cross section. The relatively thicker face strip portions provide rigidity to the door and resist vibration while the thin interconnecting portions act as hinges to permit the door to be easily guided in a curved door track having a relatively small radius. The frictional resistance of the door to sliding in a curved track can be minimized by curving the connecting portions so that they provide a very small area of contact with the track. The front surface of the sheet is preferably patterned with alternating raised and depressed areas which not only provide a pleasing appearance but also reduce the surface contact area in contact with the guides.
