摘要:
A spring device includes an intermittent accumulator and kinetics release trigger that gradually winds up to accumulate energy as driven by manual or other random intermittent kinetics and drives an kinetics release control to trigger off the spring to release kinetics to drive a load once the kinetics to the spring is accumulated to a preset value.

A device for storing and delivering elastic energy (1), which comprises: - elastic means (3) adapted to store and deliver elastic energy, - a ring (5) adapted to be connected kinematically to a machine to which the elastic energy stored in the elastic means (3) is to be delivered, or from which energy to be stored in the form of the elastic energy in the elastic means (3) is to be drawn; - a first motion transmission shaft (7) which is connected kinematically to the elastic means (3), wherein the rotation of the first shaft (7) in a first direction of rotation (A) loads the elastic means (3), - a mechanical exchange device (9, 19) configured to render the first shaft (7) integral with the ring (5) in the first direction of rotation (A) and to render the first shaft (7) free with respect to the ring (5) in a second direction of rotation (O), which is opposite with respect to the first direction of rotation (A), allowing the free rotation of the ring (5) in the second direction of rotation (O), - a second motion transmission shaft (11), the mechanical exchange device (9, 19) being configured to render the second shaft (11) integral with the ring (5) in the second direction of rotation (O), - an assembly (13) for transferring the motion from the first shaft (7) to the second shaft (11), - a freewheel mechanism (15) configured to transmit the motion from the first shaft (7) to the transfer assembly (13) only in the second direction of rotation (O) of the first shaft (7), - a mechanism for locking the elastic means (3), which can be activated in order to lock the elastic means (3) in their loaded or partially loaded configuration, wherein the deactivation of the locking mechanism releases the elastic energy stored in the elastic means (3), producing the rotation of the first shaft (7) in the second direction of rotation (O).
摘要:
L'invention concerne un appareil pour émulsionner une préparation alimentaire fluide comprenant un récipient (1) équipé d'un couvercle amovible (2) comprenant un outil rotatif (3) plongeant dans le récipient (1) pour émulsionner la préparation et un dispositif d'actionnement mécanique pour l'entraînement en rotation de l'outil rotatif, caractérisé en ce que le dispositif d'actionnement mécanique comprend un organe d'entraînement (22) relié mécaniquement à l'outil rotatif (3) et qui agit sur l'outil rotatif (3) par l'intermédiaire d'un dispositif de déclenchement à accumulation d'énergie potentielle (24) comprenant des moyens élastiques (240) propres à stocker de l'énergie potentielle, lors d'une phase d'armement du dispositif de déclenchement à accumulation d'énergie potentielle, et à la restituer à l'organe d'entraînement (22) pour entraîner l'outil rotatif (3) en rotation, lors d'une phase de déclenchement du dispositif de déclenchement à accumulation d'énergie potentielle. Le récipient est muni d'un bec verseur (11) et le couvercle comprend une partie inférieure (21 ) par laquelle il est monté sur le récipient et dans laquelle est ménagé un canal de distribution (21 b) venant en regard du bec verseur lorsque le couvercle est monté sur le récipient. Le couvercle comporte un disque (260) monté mobile à rotation sous la partie inférieure (21 ) du couvercle de sorte à s'interposer entre un volume sous-jacent du récipient et ledit canal de distribution (21b), ledit disque comprenant des secteurs angulaires (260a, 260b, 260c) aptes à être amenés respectivement en regard dudit canal de distribution par la rotation dudit disque pour réguler le débit de versement vers ledit bec verseur suivant au moins trois positions respectivement ouverte, filtrée et fermée, ledit couvercle comportant une molette de réglage (270) du disque dans l'une desdites trois positions.
摘要:
An actuator according to one embodiment of the present invention may include a fixed member and a free member. The free member is operatively engaged with the fixed member so that the free member is moveable with respect to the fixed member. The actuator also includes means for moving the free member with respect to the fixed member. An elastic element operatively associated with the free member and the fixed member is operable to store energy without a change in an overall length of the actuator.
