Abstract

ESTA INVENCION PROPORCIONA UN PROCEDIMIENTO Y UN APARATO INNOVADORES PARA DETERMINAR EL ESTADO DE CARGA DE SUJECION VISUAL Y CONTINUO DURANTE EL APRETADO Y A LO LARGO DE LA VIDA DE UN FIJADOR. ESTA INVENCION PROPORCIONA UN ELEMENTO NO DEFORMABLE (O EN ALGUNOS CASOS ELEMENTOS) (15) ADECUADAMENTE CONFIGURADO Y SITUADO DENTRO DE UN FIJADOR PARA AMPLIFICAR LA DEFORMACION DEL MISMO SEGUN SE LE APLIQUE UNA CARGA. DE ACUERDO CON UN ASPECTO DE LA INVENCION, SE CONECTA UNA PALANCA A UN PUNTO PIVOTANTE INTERNO DE UN CARTUCHO. UN EXTREMO DE LA PALANCA REPOSA SOBRE UN SOPORTE DEL FIJADOR, MIENTRAS QUE EL OTRO SIRVE DE INDICADOR. A MEDIDA QUE SE APRIETA EL FIJADOR, ESTE SE ALARGA HACIENDO QUE EL SOPORTE SE DESPLACE HACIA FUERA DEL EXTREMO DE LA PALANCA. A MEDIDA QUE EL SOPORTE SE DESPLAZA, LA PALANCA GIRA Y HACE QUE EL EXTREMO INDICADOR SE MUEVA EN RELACION CON LA ESCALA VISUAL CALIBRADA PARA INDICAR LA FUERZA DE SUJECION. SI EL FIJADOR PIERDE TENSION, SE CONTRAERA Y HARA QUE LA PALANCA GIRE HACIA SU POSICION ORIGINAL. EL MONTAJE Y CALIBRADO DEL DISPOSITIVO REQUIERE ALGO TAN SENCILLO Y BARATO COMO GIRAR UN CARTUCHO.
