Abstract
A removal seal for emergency access and egress for panels in transit vehicles has a pair of exit panel side wings separated by two key cavities. A locking strip is inserted within the two key cavities to urge the exit panel side wings against the exit panel to secure the exit panel. The locking strip may then be removed with relative ease such that the exit panel may be freed from the exit panel side wings and released. A method for achieving such a task is also disclosed herein.
Claims20
A releasable seal assembly comprising:
- a core disposed along a first axis of a seal and extending across a width of the seal;
- a first extension profile extending from the core and having a first side wing resiliently hinged to the core;
- and
- a second extension profile extending from a core and having a second side wing resiliently hinged to the core;
- the first extension profile and the second extension profile defining an exit panel slot therebetween;
- and
- the first side wing at least partially defining a first key cavity within the core that is configured to receive a first locking strip that is configured to bias the first side wing from a relaxed position, in the relaxed position the first side wing compared to the first axis of the seal forms a first angle that is less than 90 degrees. to a first biased position to secure the exit panel within the slot.
(canceled)
A seal assembly for removably securing an exit panel to a host panel, wherein the seal assembly comprises:
- a first extension profile and a second extension profile extending from a core of a seal and disposed along a first axis of the seal;
- an exit panel slot defined within the core adjacent the first extension profile;
- wherein the first extension profile has a first side wing on one side of the exit panel slot that is resiliently hinged to the core and in a relaxed position angled away from the slot, wherein a key cavity is defined within the core adjacent the first side wing;
- and
- a locking strip,
- wherein for the first extension profile, in a first state the locking strip is positioned within the key cavity of the core such that the first side wing in a first biased position secures the exit panel within the exit panel slot;
- and
- wherein in a second state, the locking strip is removed from the key cavity of the core and the first side wing returns to the relaxed position such that the exit panel may be removed from the exit panel slot.
