Abstract
1. Un sujetador rotativo para usarse al unir un primer panel con un agujero libre a un segundo panel, comprendiendo dicho sujetador una espiga generalmente cilíndrica, una cabeza ensanchada que tiene superficies de apriete en un extremo de dicha espiga, teniendo dicha espiga cilíndrica al menos una rosca helicoidal, sobresaliendo dicha rosca una altura predeterminada que se extiende desde un diámetro del fondo de la rosca hasta un diámetro del vértice de la rosca, una rampa helicoidal que comienza sustancialmente en un punto de terminación de dicha rosca helicoidal y que forman una continuación de la misma, extendiéndose dicha rampa a lo largo de la espiga hasta dicha superficie inferior de la cabeza, por lo que dicha rampa helicoidal desviará hacia fuera parte del material de al menos uno de dichos paneles incrementando por ello en gran medida la torsión de extracción del tornillo con relación al panel. 2. El sujetador rotativo de la reivindicación 1, en el que la altura inicialde dicha rampa helicoidal es aproximadamente la del diámetro del fondo de la rosca aumentando dicha altura hasta una altura máxima que es al menos igual al diámetro del vértice de la rosca. 3. El sujetador rotativo de la reivindicación 2, en el que la altura máxima de la rampa helicoidal es igual en general al doble de la altura del vértice de la rosca. 4. El sujetador rotativo de la reivindicación 1 en el que la rampa helicoidal tiene varias indentaciones. 5. El sujetador rotativo de la reivindicación 4 en el que las indentaciones forman una pluralidad de dientes que se extienden en una dirección idéntica en general a la dirección rotacional del tornillo, incrementando además dichos dientes la torsión de extracción. 6. El sujetador rotativo de la reivindicación 4, en el que las identaciones forman una pluralidad de dientes que se extienden en una direccion opuesta en general a la dirección rotacional del tornillo, incrementando dichos dientes la resistencia a la extracción. 7. El sujetador rotativode la reivindicación 1 que comprende además, una segunda rampa helicoidal que comienza en un punto diametralmente opuesta en general al punto inicial de dicha primera rampa helicoidal. 8. El sujetador rotativo de la reivindicación 1 en el que la altura predeterminada del vértice de la rosca es insuficiente para contactar los bordes del agujero libre de dicho primer panel. 9. El sujetador rotativo de la reivindicación 1, en el que la rampa helicoidal tiene una altura suficiente para enganchar los bordes del agujero libre de dicho primer panel. 10. El sujetador rotativo de la reivindicación 1, en el que dicha superficie inferior incluye un rebaje debajo de dicha cabeza, desviando dicha rampa helicoidal el material de dicho segundo panel a través de dicho agujero libre hacia arriba a dicho rebaje. 11. El sujetador rotativo de la reivindicación 1, en el que dicha rampa helicoidal tiene una extensión arqueada inferior a 360ºC seguida de una continuación de radio sustancialmente constante. 12. Elsujetador rotativo de la reivindicación 11 en el que dicha rampa y dicha continuación tienen una extensión arqueada de 360º sustancialmente. 13. El sujetador rotativo de la reivindicación 12, en el que dicha rampa tiene una extensión arqueada de 270º sustancialmente y dicha continuación tiene una extensión arqueada de 90º sustancialmente. 14. El sujetador rotativo de la reivindicación 12, en el que dicha rampa tiene una extensión arqueada de 180º sustancialmente y dicha continuación tiene una extensión arqueada de 180º sustancialmente. 15. Un sujetador rotativo.
