  • the panel latch 400 may also include a bias member 416 engaged with the second latch 404, and another similar bias member, not shown, engaged with the first latch 402.
  • the bias member may exert a pulling force on the respective latch in order to hold the latch in the latched position with the respective retention feature 430. Therefore, each bias member may exert a strong enough pulling force on the respective first or second latch to resist the force of the bias plungers 440 pushing on the removable module 442.
  • the use of a bias member on each of the first latch 402 and the second latch 404, opposed to each other may provide a balance of forces across the device module 401 to prevent the device module 401 from being urged or biased to one side or the other, thereby providing a smoother function to the panel latch 400.
  • the active nature of the panel latch 400 i.e., the actuation of the handle 406 to release the first latch 402 and the second latch 404, allows the bias members 416 to be strong enough to ensure that the device module 401, or the bias plungers 440 thereon, holds the removable module 442 correctly in place, while also providing a smooth and easy engagement and disengagement of the latches of the panel latch 400.

Abstract

Selon l'invention, dans un exemple, un verrou de panneau peut comprendre un premier verrou en prise de manière pivotante avec un panneau au niveau d'un premier point de pivot, et un second verrou en prise de façon pivotante avec le panneau au niveau d'un second point de pivot, séparé du premier point de pivot. Le verrou de panneau peut également comprendre une poignée disposée de façon mobile sur le panneau entre le premier point de pivot et le second point de pivot, un premier levier fixé au premier verrou, et un second levier fixé au second verrou. Le premier levier et le second levier peuvent tous les deux être mis en prise avec la poignée et mobiles avec celle-ci. En outre, le premier levier et le second levier peuvent déplacer le premier verrou et le second verrou, respectivement, d'une position verrouillée à une position relâchée si le premier levier et le second levier sont déplacés par la poignée.
