ABSTRACT:
A latching system and method are provided for facilitating an easier and/or smoother latching of a locking mechanism, such as a latching and catching mechanism for use with the closing of doors. In accordance with an exemplary embodiment, an exemplary latching system comprises a catch device and a latch handle configured for maintaining closure of a door. To reduce or prevent any undesirable “kick-back” of the latch handle during closure of the door, the catch device can comprise a catch spring mechanism configured to facilitate engagement with the latch handle. To provide for a substantially even balance against the catch device and/or to provide for a substantially even pressure against a door gasket, the latch handle can comprise a latch spring mechanism configured to allow engagement of the latch handle to the catch device as well as facilitate engagement of the door during closure.
