  • Publication number: 20150082704
    Abstract: A roll-up door seal arrangement includes side seals, an upper seal and a lower seal to completely seal the periphery of a roll-up door when the door is in a closed position. The seals are sized and adapted to assemble to a standard roll-up door frame without a separate or dedicated frame structure. The seals provide redundant sealing surfaces, positioned to cooperate with both the door and door frame, which ensure an effective and durable fluid tight seal between the cargo space enclosed by the roll-up door and the ambient environment. The seal may be produced by extrusion from a flexible, weather resistant material such as EPDM, thereby providing a low cost solution for sealing roll-up doors having industry standard door frame constructions. The seal is firmly engageable with the door frame, such that the seal may be installed with little or no use of secondary fixation.

    Abstract: An automatic sweep for a sliding door includes a seal member that is coupled to a housing at the bottom end of the door for movement between a raised position when the door is open and a lowered position when the door is closed, in which the seal member provides an acoustical seal for the gap that would otherwise exist at the bottom of the door. The sweep is actuated by an over-centre linkage that co-operates with an abutment adjacent the door opening. As the door reaches its closed position, the linkage is displaced from a normal extended configuration to an angled configuration, which laterally displaces an operating rod connected to a leaf-spring that then presses down on the seal member to move the member to its lowered position. When the door is opened, the over-centre linkage is moved back to its extended configuration, the rod is displaced in the opposite direction, and the leaf-spring raises the seal member.

  • Patent number: 6058655
    Abstract: A partition system includes a freestanding partition system having a pocket-defining partition, and a pocket door slidably supported on the partition system for movement into and out of the pocket. The door includes a door frame having a bottom section defining a cavity that opens downwardly, and a stiff plate-shaped light seal is operably positioned in the cavity for vertical movement by gravity between different positions as the light seal engages and rides along a floor surface. The door includes an adjustable door frame having a rectangular shape with generally square corners and straight sides, but a trailing stile of the door frame is longitudinally adjustable such that, when adjusted, the rectangular shape changes to an orthogonal shape where at least one of the sides of the door frame is angularly distorted from the rectangular shape. This allows the door frame to be adjusted to better fit a door opening.

  • Patent number: 6009669
    Abstract: An aircraft door adapted to substantially seal with a door frame. The aircraft door is provided with an edge portion which is formed to engage the door frame. The edge portion has a sealed position wherein the edge portion is engaged with the door frame. The edge portion further has an unsealed position wherein the edge portion is spaced from the door frame. The aircraft door is further provided with a substantially rigid door body and an elastic portion interposed between the door body and the edge portion. The elastic portion is selectively expandable and compressible for permitting movement of the edge portion between the sealed and unsealed positions. The aircraft door is further provided with an actuator device which mechanically couples the door body with the edge portion for selectively moving the edge portion between the sealed and unsealed positions. The actuator device comprises a shape memory metal material having a predetermined transition temperature.

  • Patent number: 5675935
    Abstract: Disclosed is a door sealing mechanism for sealing specifically the horizontal gaps between bottom rail and sill and between top rail and lintel. The door sealing mechanism comprises a sealing member including a flexible, elongated blocking portion having a length greater than the height of the horizontal gap. A retractable mounting piece is used to mount the sealing member thereon and which is retractable when the sealing member is subject to an external force. An elastic member as a spring is coupled to the retractable mounting piece, which exerts a force on the sealing member when the retractable mounting piece is in retracted position and also allows the retractable mounting piece to restore to original position after the external force on the sealing member is removed.

  • Patent number: 5577349
    Abstract: A sealing system for sealing the periphery of a door relative to a frame. The sealing system includes a multi point finger seal having at least three fingers of differing height and spacing so that a first finger may contact the door and contact of the first finger and s second finger is precluded. A second finger is sized and spaced from a third finger so that a free edge of the second finger abuts the base of the third finger. A security seal is located at the bottom of the door and includes a security flap biased into the door, wherein a cam on the frame engages the flap upon closure of the door to urge the security flap toward the floor.

  • Patent number: 5425205
    Abstract: A refrigerator includes a body forming a refrigeration compartment (for cooling or freezing). The compartment has an access opening closed by a pair of side-by-side doors that are hinged adjacent opposite vertical edges of the opening. Each door includes a frame and a slide mounted in a free edge of the slide for horizontal sliding movement. When the doors are being closed, the slides engage displacement surfaces on the body which pull the slides partially out of the frame so that resilient packing members carried by the slides are moved into contact with one another to create an air seal along a vertical interface between the two doors. A magnet on the body attracts metal plates carried by the slides to hold the doors closed. Keeper members can be mounted on the body for yieldably engaging grooves formed in the slides for aiding in holding the doors closed.

  • Patent number: 4528775
    Abstract: A sealing means for a door lacking a threshold comprises a lath of resilient material, which with a substantially plane main portion is attached to the lower edge of door leaf. A head, enlarged with respect to the main portion, is provided with sealing ridges and may be bent in relation to the attachment of the lath, so the ridges will be forced towards the floor. An actuating member, comprising a longitudinally compressible leaf spring, is fitted between the lower edge of the door leaf and the head of the lath, so it extends outside the vertical hinge edge of the door leaf. Just before the door reaches its closed position the leaf spring contacts the door frame, and will then force the portion of the head adjacent to the hinge edge downwards. During the terminal portion of the closing movement the friction between the floor and the downwardly turned portions of the ridges will "roll" the head to full contact with the floor.
