Abstract
1. Dispositivo captador de fuerzas para aparato de medición, tal como un instrumento de pesar, que comprende un bloque homogéneo paralelepipédico sensiblemente simétrico con relación a tres ejes de simetría primero, segundo y tercero perpendiculares entre sí y que presenta una cara delantera y una cara trasera perpendiculares al tercer eje de simetría, un costado inferior y un costado superior perpendiculares al segundo eje de simetría, y un primer y un segundo costados verticales perpendiculares al primer eje de simetría, así como medios de fijación de dicho bloque sobre un soporte en las proximidades del primer costado vertical y medios de unión a una placa de recepción de la fuerza a medir en las proximidades del segundo costado vertical en dicho bloque, estando practicadas, sin adelgazamiento según el tercer eje de simetría, cerca del primer costado vertical, una primera abertura transversal superior y una primera abertura transversal inferior que determina un primera zona adelgazada media, y cerca del segndo costado vertical, una segunda abertura transversal superior y una segunda abertura transversal inferior que determinan una segunda zona adelgazada media, siendo dichas zonas adelgazadas medias simétricas con relación al primer eje de simetría, estando dichas aberturas superiores e inferiores unidas respectivamente por hendiduras horizontales superior e inferior, teniendo dicho bloque igualmente entre dichas hendiduras horizontales una primera hendidura vertical que desemboca en la hendidura horizontal inferior y una segunda hendidura vertical que desemboca en la hendidura horizontal superior, estando dichas hendiduras verticales desplazadas horizontalmente, caracterizandose dicho bloque porque las hendiduras verticales determinan entre sí una zona adelgazada vertical única de menor resistencia, que presenta según el primer eje de simetría un espesor que es mínimo en el plano de los ejes de simetría primero y tercero. 2. Dispositivo, según la reivindicación 1, caracterizado porque algunas de las hendiduras verticales tienen una forma paralelepipédica y son paralelas. 3. Dispositivo, según la reivindicación 1, caracterizado porque la primera y segunda hendidura verticales están constituidas respectivamente por dos canales secantes inferior y medio y dos canales secantes medio y superior, siendo estos canales sensiblemente cilíndricos, siendo los ejes de los canales de cada hendidura vertical paralelos y estando situados en un mismo plano vertical. 4. Dispositivo, según la reivindicación 3, caracterizado porque los ejes de los canales medios pasan por el primer eje de simetria. 5. Dispositivo, según cualquiera de las reivindicaciones 1 a 4, caracterizado porque las primeras aberturas transversales tienen dimensiones más importantes que las segundas aberturas, presentando la primera zona adelgazada media un espesor según el segundo eje de simetría menor que la segunda zona adelgazada media. 6. Dispositivo, según la reivindicación 5, caracterizado porque las primeras aberturas están constituidas cada una por dos canales cilíndricos secantes de igual radio, siendo sus ejes paralelos y estando situados en un mismo plano vertical. 7. Dispositivo captador de fuerzas para aparato de medición, tal como un instrumento de pesar.
