Description

technical field [0001] This invention relates to squeeze latches for doors or panels. Background technique [0002] It is known to install squeeze latches on doors or panels. Squeeze latches are used in practice to simultaneously lock a door or panel to the frame in which the squeeze latch is mounted and to seal the edge of the panel to the frame when closed. For example, a squeeze latch may be used to compress the opening of a mounting panel provided with a gasket to provide a seal. [0003] Examples of squeeze latches are given by Southco Brochure 2000 (Southco, Inc., PA) pp. 23-69. [0004] The fixed squeeze latch provides the desired preset amount of squeeze, allowing the adjustable squeeze latch some flexibility in the amount of squeeze set. [0005] Squeeze latches typically include a latch bar that engages the frame of the closure body to lock the closure's panels. Since the squeeze latch must be operated from the outside of the closure, a mechanism must be used ...

Problems solved by technology

Therefore, in this type of application, it is not desirable to have a locking device and the lock itself that allow the internal and external communication channels of the closure to reduce the degree of isolation between the closure and the environment.
