Tensioned Flexible Operator Patents (Class 74/10.7)
  • Publication number: 20130074620
    Abstract: A semiautomatic rotational/swinging device includes a relative pivoting member, a pivoting member pivotally connected with the relative pivoting member via a pivot pin, and multiple strip-like torsion elastic members each having two end sections connected with the relative pivoting member and the pivoting member respectively. The torsion elastic members are obliquely disposed between the relative pivoting member and the pivoting member around the pivot pin. When the pivoting member and the relative pivoting member are pivotally rotated relative to each other, the end sections of the torsion elastic members are gradually shifted from the original misaligned position to an aligned position. At this time, the torsion elastic members are compressed to store energy. After the end sections pass over the aligned position, the torsion elastic members stretch from the compressed state to push the pivoting member and the relative pivoting member to automatically pivotally rotate relative to each other.

  • Patent number: 8056441
    Abstract: A control knob device has a main body defining a top surface having a ring-shaped stopping wall with two inserting openings formed thereon, and a lateral surface having a guiding recess extending upwards and downwards and a sliding slot running circumferentially and communicating with the guiding recess, with the depth thereof greater than that of the guiding recess. A shell coupled to the main body has a covering plate with two blocking portions located outside the stopping wall and adjacent to the inserting openings, and a lateral plate extending inwards to form an inserting slice corresponding to the sliding slot. The shell is coupled to the main body by the inserting slice passing through the guiding recess and inserted into the sliding slot. Two elastic ends of a spring element are inserted into the inserting openings and abut against the blocking portions for making the rotated shell return automatically.

  • Patent number: 8042429
    Abstract: A control switch includes a rotary shaft rotatably mounted therein. A switching knob is mounted to the rotary shaft and a surface of the control switch. Also, a stationary shaft is arranged beside the rotary shaft. A driving control disk and a locking control disk are sequentially and rotatably fit onto the stationary shaft so that when the switching knob on the surface is actuated, the rotary shaft is rotated to selectively drive cables through the driving control disk or the locking control disk to thereby effect switching of transmission modes and the function of locking. Thus, the amount of space required for installation is reduced and the chance of malfunctioning is also reduced and further, the costs are reduced.

  • Publication number: 20040093968
    Abstract: A rotating actuator includes a shaft (24) and a mechanical stop device (23) for generating a stop to limit the rotation of the shaft in a direction of rotation. The stop device acts upon the shaft to prevent the shaft from rotating further in the direction of rotation by blocking the shaft using a stop device acting mechanically on the shaft while enabling rotation of the shaft in a direction of rotation counter to the stop with slip in a stop arrangement. The slip is configured such that movement of the shaft in the direction of rotation counter to the stop is detectable. The stop device may include two independently triggered, mechanical stop devices. One stop device acts as a stop for limiting the rotation of the shaft to the right, and the other stop device acts as a stop for limiting the rotation of the shaft to the left.

  • Patent number: 6311574
    Abstract: A device for fine positioning of a component (1), especially for vertical fine positioning of an objective or revolving objective nosepiece (1) of a microscope, with a lever system (3) and a drive (4) for the lever system, is characterized in that the lever system (3) acts directly on a rotating part (5); that the component (1) is flexibly connected to the rotating part (5); and that the connection (6) acts such that rotation of the rotating part (5) changes the position of component (1) by unrolling the flexible connection (6) on the rotating part (5), thus causing a lifting movement of the component (1).
