20150380849 | CONTACT DEVICE FOR CONTACTING A CONTACT CONDUCTOR ARRANGEMENT - A contact device for contacting a contact conductor arrangement with at least two contact conductors. The device has at least two contact strip arrangements, each with at least one contact strip arranged on a support. The contact strip supports connect via an arrangement of parallel rods, including two parallel connecting rods, such that the contact strip supports each connect to the connecting rods in one of two parallel hinge planes at mutually spaced hinge points on mutually parallel rotational axes and form a parallelogram with the contact strips aligned parallel to each other. At least one connecting rod central axis parallel to the rotational axes is pivotally connected to a base support at a hinge point such that an advancing motion of the base support in the direction of the contact conductor arrangement causes a corresponding advancing motion of the contact strips. | 12-31-2015 |
20110139561 | Pressing-on device for a current collector and method for energy transmission - A current collector for a rail vehicle and a method for transmitting energy from power rails to the vehicle employ a contact shoe that includes an upper sliding contact surface and a lower sliding contact surface. A first pressing-on force forms a sliding contact between the upper sliding contact surface and an upper contact surface of a first power rail, when the contact shoe is in an upper sliding contact position. A second pressing-on force forms a sliding contact between the lower sliding contact surface and a lower contact surface of a second power rail, when the contact shoe is in a lower sliding contact position. The pressing-on forces may be applied by a pressing-on device attached to the contact shoe. The contact shoe may be moved into the upper sliding contact position by the first power rail, and into the lower sliding contact position by the second power rail. | 06-16-2011 |
