A blowout latch is provided to latch a first panel to a second panel. The latch is coupled to the first panel and engaged with the second panel. The latch includes a biasing mechanism which is disengagable under pressure to move the first panel relative to the second panel. The latch may also be selectively disengaged with a lesser force than that required to overcome the biasing mechanism by bypassing the biasing mechanism. When manually disengaged, the latch maintains a biasing load on a bolt of the latch. A trigger of the latch is provided to bypass the biasing mechanism and disengage a roller assembly of the latch from the second panel.

1. A pressure relief latch for latching a first panel to a second panel and provided to release under pressure or by selective disengagement, the latch comprising:a housing;a roller movable between an engaged position in contact with the second panel and a disengaged position removed from contact with the second panel;a shaft coupled to the roller for rotational movement with the roller about an axis along the shaft;a handle;a handle support coupled to the handle, coupled to the housing, and coupled to the shaft for rotational movement with the shaft;a bolt coupled to the shaft and including a channel for receiving at least a portion of the handle support, the handle support being rotatable relative to the bolt;a trigger operatively associated with the handle, the trigger including a pin normally engaged with the bolt and the handle support, the trigger being movable to release the pin from engagement with the handle support and the bolt to permit the handle support to move relative to the bolt to rotate the shaft and roller to move the roller to the disengaged position; anda biasing mechanism normally applying a force to the bolt to prevent the bolt from rotating about the axis, the bolt being configured to disengage the biasing mechanism when internal force on the roller is translated to the bolt through the shaft, handle support, and pin. 2. The latch of claim 1, further including a roller assembly rigidly coupled to the shaft for rotation therewith including a generally “L-shaped” arm having a first end coupled to the shaft and a second end coupled to the roller configured to normally engage the second panel. 3. The latch of claim 2, further including a second roller assembly spaced from the first roller, the second roller being configured to normally engage the second panel and coupled to the shaft for rotational movement with the shaft about the axis. 4. The latch of claim 1, wherein the bolt includes an aperture and a portion of the shaft is received within the aperture for rotational movement of the shaft relative to the bolt, and wherein the bolt further includes a notch and a portion of the biasing mechanism is received within the notch. 5. The latch of claim 4, wherein the biasing mechanism includes a pin normally received within the notch of the bolt. 6. The latch of claim 5, wherein the biasing mechanism further includes a slide coupled to the pin, a spring configured to bias the pin into engagement with the bolt, and an adjuster to adjust the compression of the spring. 7. The latch of claim 4, wherein the bolt further includes a ledge normally engaged with the pin of the trigger and the handle support includes a ledge normally engaged with the pin to position the pin between the handle support and the bolt. 8. The latch of claim 1, wherein the biasing mechanism includes a slide having a pin engaged with a portion of the bolt, a spring biasing the pin into engagement with the bolt, and an adjuster to adjust the compression of the spring. 9. The latch of claim 8, wherein the adjuster is a threaded screw. 10. The latch of claim 8, wherein the pin is normally received within a notch of the bolt. 11. The latch of claim 1, wherein the trigger is pivotally coupled to the housing of the latch configured to be coupled to the first panel, and wherein pivoting movement of the trigger disengages the locking pin from the bolt and the handle support to permit the handle support to move relative to the bolt and bypass the biasing mechanism to move the roller to the disengaged position. 12. The latch of claim 1, wherein the trigger includes a spring to bias a body of the trigger to an upright position where the pin of the trigger is engaged with the bolt and the handle support. 13. The latch of claim 12, wherein the housing is configured to be coupled to the first panel and the handle is pivotally coupled to the housing, and wherein the trigger is pivotally coupled to the handle and movement of the trigger against the spring of the trigger from the upright position to a depressed position disengages the pin from the handle support and the bolt to permit the handle to rotate relative to the housing. 14. The latch of claim 13, wherein the handle support is pivotally coupled to the handle and movement of the handle support with the handle causes the handle support to rotate about the axis and rotate the shaft to move the roller to the disengaged position. 15. The latch of claim 1, wherein the handle support includes in aperture for receiving a portion of the shaft, and wherein the shaft includes an aperture generally perpendicular to the axis and the latch further includes a pin received within the shaft to rigidly couple the shaft to the handle support. 16. The larch of claim 15, further including the housing configured to be coupled to the first panel and the handle being pivotally coupled to the housing, and wherein the handle support is coupled to the handle for movement with the handle. 17. The latch of claim 16, wherein the handle support includes a downward facing surface normally engaged with the pin of the trigger and the bolt includes an upward facing surface normally engaged with the pin of the trigger so that the bolt and handle support are prevented from moving relative to one another.
