A hand brake having mechanism for retaining the hand brake in a substantially released and hold position to prevent unwanted application of the railway car brakes due to vibration or other energy sources during railway car motion. Such mechanism includes at least one spring(102) mounted to the hand brake housing substantially engaging a release lever(70) disposed within a quick release mechanism so as to prevent reverse rotation of the release lever causing an unintended take-up of the chain.

L'invention porte sur un frein à main équipé d'un mécanisme de retenue du frein à main dans une position sensiblement desserrée et maintenue afin d'empêcher une application indésirable des freins du wagon en raison de la vibration ou d'autres sources d'énergie pendant le mouvement du wagon. Ce mécanisme comprend au moins un ressort (102) monté sur le logement du frein à mains qui vient sensiblement en prise avec un levier de desserrage (70) disposé dans un mécanisme de desserrage rapide de manière à empêcher la rotation inverse du levier de desserrage, ce qui entraîne un enroulement imprévu de la chaîne.
