  • Patent number: 10470563
    Abstract: A height-adjustable piece of furniture includes a lower part, an upper part, an actuating device, first and second reference sections and a deformation sensor. Distance between the lower and upper parts can be adjusted by the actuating device. The deformation sensor is arranged to detect change between the first and second reference sections and is connected to the actuating device such that a signal of the deformation sensor can be transmitted to the actuating device. The actuating device is configured to stop the change in distance between the lower and upper parts if the signal transmitted by the deformation sensor corresponds to a change in distance that exceeds predefined threshold values. A cable protector is also provided for a cable to be mounted, and is coupled to the first and second reference sections such that tensile force acting on the cable causes change between the first and second reference sections.

  • Patent number: 5665947
    Abstract: A cable switch actuating mechanism is provided with a shaft and a cam structure that slides on the shaft. When the associated cable is pulled to exert an axial force on the shaft, the cam actuator is pushed by the shaft into a deactuating position that moves a switch operator plunger against a plunger of an associated electrical switch. If the cable breaks, the reduction enforced on the shaft causes an internal spring to move the shaft against the cam structure and, as a result, move the switch operator into its deactuating position. Appropriate gaps between the opposite ends of the cam structure and associated surfaces of the shaft allow for thermal expansion and contraction of the cable without adverse affects on the mechanism.

  • Patent number: 5401924
    Abstract: A remote battery switch for motor vehicles provides for the remotely controlled disconnection and connection of the vehicle electrical system, for long term storage or carjacking threats. The switch attaches directly to the side terminal or top post connector of a standard motor vehicle battery, without further need for additional structural attachment. A cord or cable is run from the battery switch to the vehicle passenger interior, and is preferably discreetly accessible by the vehicle operator should the need arise. The cord or cable serves to open the switch by releasing a magnetic contact and withdrawing the magnetic switch bar against a spring, whereupon the switch bar is caught and retained by a double acting catch. A second pull on the cord releases the catch, whereupon the spring pulls the magnetic switch bar into magnetic contact with the other switch point to close the circuit. Thus, the switch may be remotely opened and closed using purely tensile forces in the cord.

  • Patent number: 5237133
    Abstract: A vehicular engine safety switch having two or more functional positions, which includes a removable restraining device such as a clip or a pin which is flexibly attachable to the body or apparel of the vehicle operator. In the primary functional mode, the clip is in place on the switch and the engine may be started. Movement of the operator from the switch by a distance determined by the length of a flexible lanyard removes the clip, and the switch returns under spring pressure to an OFF position. The engine may be restarted with or without the clip in place, the latter condition occurring, for example, if the operator has been ejected from the vehicle. The safety action of the switch is achieved by the interaction of a specially formed detent sleeve and spring-loaded detent ball, and a lock cylinder rotationally and axially spring biased relative to the detent sleeve.

  • Patent number: 5041705
    Abstract: A piston operated by a cable stretched out within hand reach along a dangerous zone actuates a tappet whose movements are transmitted to a slider. The slider in turn compresses a spring until in a first phase, before any switch actuation, a pawl engages a groove in the slider. This prevents return of the tappet to its rest position, whereby any attempt to simulate a machine breakdown by fraudulent actuation of the device leaves a trace in the device even before effective switch actuation has occurred. In a second phase the force of the spring exceeds the force necessary to retract locking pins of a striker which is therefore released abruptly to operate the switch. To restore the device to its standby state, a lock plug carrying a cam adapted to release the pawl from the groove in the slider is rotated by means of a key.

  • Patent number: 5003135
    Abstract: A cable-controlled electrical safety switch device comprises a piston 15 tensioning a cable 2 under the action of a spring 23 via a rod 10 and a screw thread 12a for adjusting the tension of the spring and of the cable. A piston groove 25 actuates a push member 28 for the switch 40. The piston is angularly adjustable. The flank 32 of the groove remote from the spring is helicoidal. When the cable is long, a higher tension is selected so that the groove flank 31 moves away from the push member 28. This distancing is desirable in order that any length variations due to heat--which are greater with a long cable--may be prevented from triggering the switch. The clearance between the other flank 32 and the push member 28 is then corrected by rotation of the piston.
