De acuerdo con lo representado en las figuras, el eje (1) está asociado a un elemento elástico y/o flexible envolvente o semienvolvente (6) realizado preferentemente en alambre o varilla de acero de resortes o bien por un simple elemento elástico en forma de anillo de elastómero, actuando en todos los casos entre un punto fijo y una parte del eje giratorio (1) y del bloque excéntrico con el que está solidarizado dicho eje, estando dicho bloque destinado a recibir el par de giro del elemento elástico. La disposición más detallada se puede observar en las figura 5 a 7, en las que un bucle cerrado (6) tiene extremos (7) y (8) a lo largo de un eje mayor y otros (9) y (10) a lo largo de un eje menor, manera que el extremo (8) queda retenido en tope fijo formado por la patilla (12), y el extremo opuesto (7) abraza el saliente excéntrico (11) solidario del eje (1), de manera que por la acción del bucle elástico (6) sobre dichos elementos se genera un par de fuerzas transversal sobre el bloque saliente (11) que determina las dos posiciones estables del eje (1), tal como se han representado en las figuras 5 y 7, representando la figura 6 una posición intermedia inestable entre una y otra de dichas posiciones estables que corresponden a sendos ejes indicados con las líneas de trazos (13) y (14) en las figuras 5 y 7.According to what is represented in the figures, the shaft (1) is associated with an elastic and / or flexible element envelope or semi-envelope (6) preferably made in spring wire or steel rod or by a simple elastic element in the form of an elastomer ring, acting on all cases between a fixed point and a part of the rotating shaft (1) and of the eccentric block with which said axis is in solidarity, said block being intended to receive the torque of the elastic element. The more detailed arrangement can be observed in Figures 5 to 7, in which a closed loop (6) has ends (7) and (8) along a major axis and others (9) and (10) along of a minor axis, so that the end (8) is retained in abutment fixed formed by the pin (12), and the opposite end (7) hugs the eccentric projection (11) integral with the shaft (1), so that by the action of the elastic loop (6) on said elements generates a pair of transverse forces on the projecting block (11) which determines the two stable positions of the shaft (1), as they have represented in figures 5 and 7, representing figure 6 an unstable intermediate position between one of these stable positions corresponding to two axes indicated with the dashed lines (13) and (14) in figures 5 and 7.
El funcionamiento del dispositivo biestable sobre el eje (1) permitirá la sujeción de una viga en disposición superior o correa (15), figura 8, que, centrada en los bloques de centraje (4), quedará solidarizada sobre la viga o portacorrea (3) por medio de la excéntrica (5) solidaria del eje (1).The operation of the flip-flop device on the shaft (1) will allow the attachment of a beam in arrangement upper or belt (15), figure 8, which, centered on the blocks of centering (4), will be supported on the beam or belt carrier (3) by means of the eccentric (5) integral with the shaft (1).
La realización del elemento envolvente o semienvolvente podrá corresponder a la realización mostrada en la figura 9, en la que se aprecia el elemento semienvolvente (16) que es incompleto, mostrando los extremos abiertos (17) y (18) y presentando por lo demás una estructura similar a la de las figuras anteriores, ejerciendo por lo tanto la misma acción sobre el bloque excéntrico (11), que determina las dos posiciones estables del eje (1).The realization of the envelope element or Half-envelope may correspond to the embodiment shown in the Figure 9, which shows the semi-solvent element (16) that is incomplete, showing open ends (17) and (18) and otherwise presenting a structure similar to that of the figures previous, therefore exercising the same action on the block eccentric (11), which determines the two stable positions of the shaft (one).
En la figura 10 se ha mostrado otra realización alternativa en la que el elemento envolvente (19) está constituido por una tira de material elastómero, por ejemplo, una goma especial que actúa de modo similar a las realizaciones anteriormente mostradas, determinando por lo tanto las mismas posiciones estables para el eje (11).Another embodiment is shown in Figure 10. alternative in which the envelope element (19) is constituted by a strip of elastomeric material, for example, a special rubber which acts similarly to the embodiments above shown, therefore determining the same stable positions for the shaft (11).
Un ejemplo concreto de realización del eje (1) y del asa de accionamiento (2) se ha representado en la figura 11, en la que se aprecia el eje (1) dotado de la excéntrica superior de bloqueo (5), atravesando una placa (20) que queda soldada en la cara inferior de la viga (3), tal como se aprecia en las figuras 1 y 3. Dicha placa (20) presenta la aleta (12) que actúa de punto fijo de apoyo y que quedará abrazada por el elemento envolvente (6), que en esta figura se ha representado en forma de bucle cerrado. Al propio tiempo, la placa (20) presenta rebatimientos en los otros tres lados indicados con los numerales (21), (22) y (23) para protección del elemento envolvente y del conjunto de manecilla y bloque excéntrico contra proyecciones de hormigón y otros. En esta realización, la manecilla (2) presenta una amplia zona (24) que recibe el extremo del eje (1) fijado mediante un tornillo (25) y que presenta el saliente o bloque excéntrico (26) que corresponde al saliente excéntrico representado con el numeral (11) en las otras figuras. Es evidente que al solidarizar la palanca (2), (24) con el extremo del eje (1), existe una solidarización entre dicho eje (1) y el saliente (26), adoptando la configuración práctica que corresponde a lo representado en las figuras. El eje (1) presenta además un saliente o valona intermedia (27) que actúa como tope axial.A concrete example of embodiment of the shaft (1) and of the drive handle (2) is shown in Figure 11, in which shows the axis (1) provided with the upper eccentric of block (5), going through a plate (20) that is welded in the underside of the beam (3), as seen in figures 1 and 3. Said plate (20) has the fin (12) acting as a fixed point of support and that will be embraced by the envelope element (6), which in this figure it has been represented as a closed loop. To the own time, the plate (20) exhibits overflows in the others three sides indicated with the numerals (21), (22) and (23) for protection of the envelope element and the hand assembly and Eccentric block against concrete and other projections. In this embodiment, the hand (2) has a large area (24) that receives the shaft end (1) fixed by means of a screw (25) and presenting the eccentric protrusion or block (26) that corresponds to the eccentric projection represented by the numeral (11) in the Other figures It is evident that when solidarity lever (2), (24) with the end of the shaft (1), there is a solidarity between said axis (1) and projection (26), adopting the practical configuration that corresponds to what is represented in the figures. The shaft (1) presents also an intermediate projection or wall (27) that acts as a stop axial.
