  • Patent number: 10378250
    Abstract: A lock for closing a door with respect to a frame. The lock includes a lock body mounted on the door and a striker mounted on the frame, or vice versa. The lock body includes a catch element mounted so as to rotate between a striker keep position and a striker release position; elastic means suitable for driving the catch element from the striker keep position to the striker release position; a lever suitable for moving between two positions, a closing position in which it maintains the catch element in the striker keep position and an opening position in which it is disengaged from the catch element; and a service actuator suitable for applying a force f on the lever so as to bring it from the closing position to the opening position. The lock body further includes an emergency SMA actuator suitable for applying a force on the lever so as to bring it from the closing position to the opening position.

  • Patent number: 9664182
    Abstract: An SMA wire actuating element is described, having a shape memory alloy wire intended to be operably connected to an actuatable element of an actuator device, and a first and a second elongated elements made of a non-SMA material. The elongated elements are respectively restrained at a first end thereof to the ends of the shape memory alloy wire by way of crimping means of the SMA wire actuating element. The SMA wire actuating element further has a first and a second connection means intended to be operably connected to a body of the actuator device. The elongated elements are respectively restrained at a second end thereof to the connection means, whereby the portion of each elongated element comprised between its first and second ends is free to move between the crimping means and the connection means.

  • Patent number: 9630560
    Abstract: A shape memory actuator includes a supporting body, a driven element pivotably mounted on the supporting body and in permanent contact with a driving element whose movement is determined by a SMA actuating member and by at least one resilient return member acting in opposition to the SMA actuating member. The driven element is able to take two stable positions under the action of a bistable moving system connecting the driving element to the driven element such that each toggling between the two stable positions is due to an activation of the SMA actuating member, the latter being arranged together with the bistable moving system. The resilient return member, the driving element and the driven element on a same side of the supporting body are in a substantially co-planar arrangement.

  • Patent number: 9171686
    Abstract: A bistable electric switch is described. The switch has as actuators a pair of opposing SMA wires acting on a drive element integral with a snap-action spring so as to toggle the snap-action spring between two stable positions corresponding to two operating positions of the switch, the drive element being shorter than the distance existing between the two opposing SMA wires when one of the SMA wires is contracted and the other SMA wire is uncontracted. The entire force exerted by the activated SMA wire is used to overcome the resistance of the snap-action spring.

  • Patent number: 8899829
    Abstract: A temperature-sensitive label is described. The temperature-sensitive label has a temperature-sensitive system having a filiform shape memory member that has a first end portion having a terminal part fixedly secured to a first contact member, a second end portion having a terminal part restrained by a second contact member in a non-permanent way, and a central curved portion. The central curved portion is in the martensitic phase while the first and second portions are in the austenitic phase at a same environmental temperature above a critical threshold temperature to be monitored by the label such that in case of exposure to a temperature lower than the preset critical threshold temperature the end portions of the filiform shape member perform a phase transition, from austenitic phase to martensitic phase, which causes its irreversible disengagement from the restraint formed by the second contact member.

  • Patent number: 8408365
    Abstract: A locking device for preventing the rotation and/or the axial movement of a pin includes a coil spring wound around at least a portion of the pin and having one end rigidly connected to a support structure. In its undeformed condition, the spring has an internal diameter smaller than the diameter of the pin, whereby in its resting condition the spring is tightened around the pin to prevent a rotation thereof at least in a direction or an axial movement in any direction. The device includes shape memory means for causing the unwinding of the turns of the spring for the purpose of temporarily releasing the pin.
