Patent number: 7922201Abstract: The invention relates to a swivelable roll bar, in particular for construction vehicles, with two vertical carriers, each of which has a pair of spars, whereby in each, one spar is connected swivelably through a link joint with the another spar, and the link joint comprises a lock and a stop. The stop consists of a joint stiffener, which is built as an extension of one spar and partially grips about the end of the other. In addition to that, the lock has a continuously adjustable final control element, with which the joint stiffener can be braced against the other spar. With the grip about the other spar, the flexural strength of the link joint of the swivelable roll bar is increased. Further, the bracing of the joint stiffener against the other spar eliminates the play in the link joint. The joint stiffener is preferably built as a U-shaped tubular segment that is attached to the latter as an extension of the spar.Type: GrantFiled: February 19, 2010Date of Patent: April 12, 2011Assignee: BOMAG GmbHInventors: Hans-Werner Kürten, Karl-Harmann Mötz

Patent number: 6698531Abstract: A hand-guided vibration tamper, which is driven by a motor laterally cantilevered on the tamper head, is provided with guard plates covering its underside and lateral sides. The underside and lateral guard plates are connected to a housing for the motor, and the underside guard plate is fastened near its free end to the motor and/or an air circulation hood for the motor. Preferably, the underside guard plate is a thick-walled aluminum plate screwed together with the lateral guard plates and extends beyond to protect the air circulation hood with its extension. Advantageously, the motor is also protected by a substantially closed, upper covering connected to the lateral guard plates.Type: GrantFiled: March 27, 2002Date of Patent: March 2, 2004Assignee: Bomag GmbH & Co., oHGInventor: Hans-Werner Kürten

Patent number: 4505356Abstract: An ergonomically advantageous operator's seat and controls arrangement for tandem road rollers comprises on the transverse center line of an operator's platform operator's seats arranged side by side and rotatable about vertical axes. A control stick pivotable in two mutually orthogonal directions is located on the longitudinal center line of the operator's platform in the middle between the operator's seats. Two steering devices are mounted with their steering columns rotatable about a longitudinal, central axis on two opposite transverse sides of the platform. Thus by rotation of the seats through 180.degree., four possible seat positions for the operator are achieved. By pivoting the control stick towards the respective occupied seat and by corresponding rotation of one steering device to in front of this seat, all controls are always within easy reach of the operator.Type: GrantFiled: March 1, 1983Date of Patent: March 19, 1985Assignee: Losenhausen Maschinenbau AG.Inventors: Heinrich Baier, Hans-Georg Waschulewski, Hans-Werner Kurten
