Abstract

"TRAVA DE LAçO SEM FIM". Sob um aspecto, a invenção proporciona uma trava para um laço sem fim incluindo uma roda motriz adaptada para ser acionada ou não acionada. Um laço sem fim pode ser previsto, para se engatar com a roda motriz e adaptado para ser acionado pela roda motriz para deslocar um dispositivo, tal como uma barra de segurança, conectada com o laço sem fim. Uma guia pode ser provida, compelida contra o laço sem fim em uma posição espaçada da roda motriz. Uma trava pode ser prevista, para se engatar com o laço sem fim para inibir o deslocamento do laço sem fim, a guia sendo posicionada para compelir o laço sem fim a desengatar-se da trava quando o laço sem fim é acionado pela roda motriz. A trava pode ser acionada por uma força aplicada ao dispositivo conectado com o laço sem fim quando a roda motriz não está sendo acionada. (FIGURA 3).
