CA 2528981

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.

Procédé et système de verrouillage destinés à rendre plus aisé et/ou plus souple le fonctionnement d'un mécanisme de verrouillage, tel qu'un mécanisme à loquet et à verrou utilisé pour fermer les portes. Selon un mode de réalisation cité à titre d'exemple, un système de verrouillage comprend un dispositif à loquet et une poignée de verrouillage configurés pour maintenir une porte fermée. Afin de réduire ou d'éviter tout phénomène de recul indésirable de la poignée de verrouillage pendant la fermeture de la porte, le dispositif à loquet peut comprendre un mécanisme à ressort de loquet agencé pour faciliter l'enclenchement avec la poignée de verrouillage. Afin d'assurer un équilibre sensiblement uniforme au niveau du dispositif à loquet et/ou une pression sensiblement égale à l'encontre d'un joint de porte, la poignée de verrouillage peut comprendre un mécanisme à ressort de verrouillage agencé pour permettre l'enclenchement entre la poignée de verrouillage et le dispositif à loquet ainsi que pour faciliter l'enclenchement de la porte pendant la fermeture.
