  • Patent number: 11326393
    Abstract: A sliding door system (105) includes a track assembly (120) and a door (125) slidably connected to the track. Seals (245, 250, 605, 610, 300, 500) disposed about the door limit sound and/or infectious materials from passing thereby. One or more of the seals (245, 250) are disposed between the door and the track assembly. One or more other seals (605, 610) are disposed between the door and a wall to seal around the trailing end of the door. The system may also include a door dock (130) with one or more seals (300, 500) to seal around the leading end of the door. The system can also include a drop seal assembly (700) that selectively seals off a gap between the bottom of the door and the floor.

  • Patent number: 11118395
    Abstract: A sealing device of a sliding door having a slidably mounted door leaf has a drop-down seal having a sealing strip and a lowering mechanism for automatically lowering and raising the sealing strip. The lowering occurs against a restoring force. The sealing device also has an activation unit for activating the drop-down seal. The activation unit has a contact surface, which is directed upward in the lowering direction, and a contact element, which lies against said contact surface during the closing of the door leaf and thereby actuates the drop-down seal. In this way, the weight of the door leaf can be used for the lowering of the sealing strip. Furthermore, a position in which the restoring force does not influence a sliding motion of the door leaf in the longitudinal direction of the sealing strip can be achieved.

  • Patent number: 10934772
    Abstract: A self-adjusting retractable screen with an adjustable bottom bar assembly is disclosed herein. The adjustable bar assembly comprises a bottom bar assembly, an adjustable arm assembly, and a pivot assembly. The adjustable arm assembly is pivotally engaged with the bottom bar assembly via the pivot assembly, which is disposed in the horizontal center of both the bottom bar assembly and the adjustable arm assembly. During the deployment of the retractable screen, while the bottom bar assembly remains level, one side of the adjustable arm assembly can pivot upwards when the side first contacts a high point of an uneven surface, i.e., floor. When the screen retracts with the adjustable bottom bar assembly off the uneven surface, the adjust arm assembly has means to return itself to a level position.

  • Patent number: 7082727
    Abstract: A window assembly which includes at least some components which may be assembled in a snap-fit manner. In certain example embodiments, a combination of rotation/pivoting insertion, and a snap-fit assembly engagement of one or more components may be utilized in assembly. For example, a component may be engaged with a portion of another component, and then rotated and/or pivoted about a pivot axis until a portion of the component becomes engaged with a part of the window in a snap-fit manner. The combined use of rotation/pivoting about a pivot axis and snap-fit engagement allows for self-alignment to be realized during assembly thereby simplifying the assembly process.

  • Patent number: 6266924
    Abstract: A multi-finger door frame seal which results in reduced hinge bind and which creates a predetermined sound upon opening of the door is disclosed. The frame seal is mounted on the stop on the hinge jamb, while on the rabbett on the lock jamb thereby reducing hinge bind during closing of the door. Use of the multi-finger frame seal according to certain embodiments results in a generation of a predetermined sound upon opening of the door. Also disclosed is a security seal system for use adjacent the bottom of the door. The security seal includes a flap which may be either gravity-actuated or spring-actuated. In spring-actuated embodiments, a cam forces the security flap downward into the closed position as the door is closed. While in gravity-actuated embodiments, closing of the door results in gravity causing the security flap to move downward into the closed position where it is maintained while the door is closed.

  • Patent number: 4703586
    Abstract: A mechanism for automatically blocking the gap between the bottom edge of a door leaf, hung to open and close within a surrounding frame, and the adjacent threshold, when the door is closed; and automatically unblocking that gap when the door starts to open again, comprises an elongate bar housed above a strip of material in the bottom edge region of the door leaf. The bar and strip of material each are coupled to respective attraction/repulsion elements. One element is a magnet and the other is a piece of material having a positive reaction to a magnet, typically a further magnet. One end of the bar or an auxiliary member coupled to the bar protrudes from an edge of the door adjacent the door frame. The arrangement is such that, with the door open, the strip of material is raised clear of the adjacent threshold.

  • 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.
