Patent number: 10807226Abstract: A range of power tools each includes motor and transmission housings with an electric motor and a transmission mechanism mounted respectively therein, with the transmission mechanism using the rotary output of the motor to drive a cutting tool. An intermediate housing is sandwiched between the motor and transmission housings. Each of the motor housings is the same in shape, and the length of the electric motors in each of the power tool is different to the length of the electric motors in the other power tools in the range. The transmission housing is positioned differently relative to the motor housing in each power tool to accommodate the difference in length in the electric motor in that power tool, the shape of the intermediate housing in each power tool varying relative to the other intermediate housings to accommodate the difference positions of the transmission housings relative to the motor housings.Type: GrantFiled: July 15, 2015Date of Patent: October 20, 2020Assignee: Black & Decker Inc.Inventors: Ralf Bernhart, Martin Soika, Bruno Ruethers

Patent number: 7864302Abstract: A scan sensor emits detection beams for detecting objects in a scanning area within a scanning plane. The position of the scanning plane is changed by pivoting the sensor device in a scanning area, to produce multiple detection planes. Detection points of objects in the surroundings of the sensor device are detected by the detection beams in the detection planes. Lines are extracted from the detection points of a respective detection plan. Measuring points are determined at the intersection points of the lines with one or more predetermined measuring planes. The measuring points in a respective measuring plane are classified into blocks and lines are extracted on a block basis from the measuring points of the blocks generated, as a result of which structures of objects in the measuring planes are determined.Type: GrantFiled: February 1, 2007Date of Patent: January 4, 2011Assignee: Siemens AktiengesellschaftInventors: Sebastian Pook, Martin Soika

Patent number: 7705497Abstract: A power tool cooling system comprises a cooling fan disposed on a motor in a position between the upper field coil and the lower commutator. A transmission housing encapsulates the transmission mechanism. During operation, the fan is driven by the motor and draws air axially through the motor and expels the air radially outwardly through holes in the outer housing of the motor. This causes air to be drawn in through the air vents formed on the top of a tool housing, in the side of the housing and between the housing and a battery pack. The cool air flows outside of the transmission housing, but inside the tool housing such that air does not pass through the transmission mechanism. A plurality of motor openings are also formed in the outer housing of the motor to enable cool air to pass into the motor to cool the motor.Type: GrantFiled: December 29, 2005Date of Patent: April 27, 2010Assignee: Black & Decker Inc.Inventors: Klaus-Dieter Arich, Erhard Benner, Manfred Droste, Uwe Nemetz, Martin Soika, Michael Kunz

Patent number: 7696894Abstract: In the method for determining a relative position of a mobile unit by comparing scans of an environment, scans of an environment of the mobile unit are recorded continuously by a distance sensor and stored in a memory. Furthermore the processing unit compares a first scan with a second scan, with a relative position of the mobile unit at the time of the second scan being determined in relation to a position at the time of the first scan. The method is characterized by the fact that the processing unit compares the first scan iteratively with subsequent scans, with a new relative position of the mobile unit at the time of the relevant subsequent scan being determined relative to the position at the time of the first scan, and with the last relative position determined in each case being taken into account as a-priori information.Type: GrantFiled: July 31, 2006Date of Patent: April 13, 2010Assignee: Siemens AktiengesellschaftInventors: Michael Fiegert, Martin Soika

Patent number: 7306049Abstract: A gear wheel is rotatably mounted on a drive shaft. The drive shaft has a plurality of longitudinal splines formed thereon. A drive sleeve surrounds the drive shaft and has a plurality of the inner splines formed on its interior surface. The inner splines slidably intermesh with outer splines of the drive shaft such that the drive sleeve can slide up and down on but cannot rotate relative to the drive shaft. A coil spring biases the drive sleeve downwardly. Drive sleeve teeth are formed around the bottom edge of the drive sleeve. Corresponding gear plate teeth are formed on the upper surface of the gear wheel and are adapted to engage the drive sleeve teeth when the drive sleeve is in its downward most position under the influence of the coil spring. In this position, the gear wheel is operatively coupled to the drive shaft.Type: GrantFiled: December 21, 2005Date of Patent: December 11, 2007Assignee: Black & Decker Inc.Inventors: Martin Soika, Andreas Hanke, Uwe Nemetz, Michael Kunz
