The invention provides an automatic latch having a first latch member and a second latch member. The first latch member may include an opening and a cam structure. The second latch member may include a pivoted structure that includes a protrusion and a cam surface. The second latch member may also include a spring having first and second spring portions. As the cam structure is advanced towards the cam surface of the pivoted structure such that the cam structure passes over the protrusion of the pivoted structure, the first spring portion applies a bias causing the protrusion to protrude through the opening of the first latch member when the cam structure clears the protrusion. Thus, the latch is placed in a locked configuration. When in the locked configuration, the second spring portion applies a bias that tends to separate the first latch member from the second latch member, so that the latch may spring apart when intentionally unlocked.
La présente invention concerne un loquet automatique qui possède un premier élément de loquet et un second élément de loquet. Le premier élément de loquet peut comprendre une ouverture et une structure de came. Le second élément de loquet peut comprendre une structure tournée qui comprend une protubérance et une surface de came. Le second élément de loquet peut également comprendre un ressort qui possède des première et seconde parties de ressort. Lorsque la structure de came est avancée vers la surface de came de la structure tournée de sorte que la structure de came passe par-dessus la protubérance de la structure tournée, la première partie de ressort applique une sollicitation qui force la protubérance à faire saillie à travers l'ouverture du premier élément de loquet lorsque la structure de came quitte la protubérance. Ainsi, le loquet est placé dans une configuration verrouillée. Une fois dans la configuration verrouillée, la seconde partie de ressort applique une sollicitation qui a tendance à séparer le premier élément de loquet du second élément de loquet, de sorte que le loquet puisse se séparer de façon élastique lorsqu'il est ouvert involontairement.
