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.
Claims20
A sliding door system, comprising:
- a track assembly including a track having a roller channel;
- a door movably connectable to the track, wherein the door has an open configuration and a closed configuration;
- one or more track assembly seals disposed between the track assembly and the door;
- and
- a drop seal assembly connected to a lower end of the door, wherein the drop seal assembly is configured to seal the gap between the door and a floor when the door is moved from the open configuration to the closed configuration, and wherein the drop seal assembly comprises:
- a scissor mechanism having a first scissor member pivotally attached to a second scissor member, the first scissor member connected to an activation member to form a first plane, and the second scissor member connected to a biasing member in a second plane that is different from the first plane
- wherein depression or release of the activation member upon closing or opening the door, respectively, causes the first scissor member to rotate relative to the second scissor member, thereby moving the second plane vertically toward or away from the first plane, and correspondingly engaging or disengaging the drop seal assembly from the floor, and wherein the activation member and biasing member extend in the substantially same longitudinal direction.
4 more elements
A sliding door system, comprising:
- a track assembly including a track having a roller channel;
- a door slidably connected to the track assembly to enable the door to move between an open configuration and a closed configuration, the door having a leading end and a trailing end;
- a drop seal assembly configured to actuate from a non-sealed configuration to a sealed configuration when the door is moved from the open configuration to the closed configuration, thereby sealing a gap between the door and a floor, and where in the drop seal assembly comprises:
- a scissor mechanism,
- an activation member that extends from a leading end of the door when the door is in the open configuration and is attached to a first end of a first scissor member of the scissor mechanism, wherein the activation member is pressed inward into the door when the door is moved into the closed configuration,
- a drop seal that is attached to a second end of the first scissor member, wherein the drop seal is linked to the activation member such that inward movement of the activation member causes the drop seal to be lowered, and
- a biasing member attached to a first end of a second scissor member of the scissor mechanism, wherein the biasing member is linked to the activation member and the drop seal at the scissor mechanism such that the biasing member raises or retracts the drop seal when the door is moved from the closed configuration to the open configuration;
- and
- a door dock configured to receive or engage the leading end of the door, the door dock comprising one or more docking seals that engage the leading end of the door when the door is closed, and wherein the activation member and biasing member extend in the substantially same longitudinal direction.
6 more elements
A sliding door system, comprising:
- a sliding door, wherein the door has an open configuration and a closed configuration;
- and
- a drop seal assembly, wherein:
- the drop seal assembly is configured to actuate from a non-sealed configuration to a sealed configuration when the door moves from the open configuration to the closed configuration, thereby sealing a gap between the door and a permanent structure;
- and
- the drop seal assembly is configured to actuate from the sealed configuration to the non-sealed configuration when the door moves from the closed configuration to the open configuration, thereby unsealing the gap between the door and the permanent structure, and
- the drop seal assembly comprises:
- a scissor mechanism,
- an activation member that extends from a leading end of the door when the door is in the open configuration and is attached to a first end of a first scissor member of the scissor mechanism, wherein the activation member is pressed inward into the door when the door is moved into the closed configuration,
- a drop seal that is attached to a second end of the first scissor member, wherein the drop seal is linked to the activation member such that inward movement of the activation member causes the drop seal to be lowered, and
- a biasing member attached to a first end of a second scissor member of the scissor mechanism, wherein the biasing member is linked to the activation member and the drop seal at the scissor mechanism such that the biasing member raises or retracts the drop seal when the door is moved from the closed configuration to the open configuration, and wherein the activation member and biasing member extend in the substantially same longitudinal direction.
