Title (EN) PIVOTING ACTUATOR AND A POP-UP TARGET INCORPORATING SAME
(FR) ACTUATEUR PIVOTANT ET CIBLE INSTANTANEE L'INCORPORANT
Abstract:
(EN) A gas actuator and a pop-up target and a door incorporating the gas actuator are disclosed. The gas actuator comprises support surfaces (24, 26), pivoting surfaces (64, 66) pivotably coupled upon the support surfaces (24, 26), respectively, and flexible and inflatable members (28, 20) disposed for pivoting the pivoting surfaces (64, 66) with respect to the support surfaces (24, 26) between a first and a second position. The members (18, 20) act over a relatively large area between the support surfaces (24, 26) and the pivoting surfaces (64, 66). The magnitude of the pivoting force produced by the members (18, 20) increases to a maximum and thereafter decreases as the pivoting surface (64) pivots upwards. An accumulator (104) allows for relatively low flow rates of gas from a source of compressed gas (102) and provides relatively high flow rates of compressed gas to the members (18, 20).
(FR) Un actuateur à gaz, une cible instantanée et une porte intégrant l'actuateur à gaz font l'objet de l'invention. L'actuateur à gaz comprend des surfaces de support (24, 26), des surfaces pivotantes (64, 66) accouplées en rotation aux surfaces de support (24, 26) respectivement et des éléments flexibles et gonflables (28, 20) disposés pour faire pivoter les surfaces pivotantes (64, 66) par rapport aux surfaces de support (24, 26) entre une première et une deuxième position. Les éléments (18, 20) agissent sur une zone relativement grande entre les surfaces de support (24, 26) et les surfaces pivotantes (64, 66). L'intensité de la force pivotante produite par les éléments (18, 20) augmente jusqu'à un maximum et ensuite diminue en même temps que la surface pivotante (64) pivote vers le haut. Un accumulateur (104) permet la production de débits de gaz relativement faibles à partir d'une source de gaz comprimé (102) et fournit des débits de gaz comprimé relativement élevés aux éléments (18, 20).
