Patent number: 7975388Abstract: A circular power saw (10), composed of a saw assembly (12) with a housing (14, 16) that encloses a motor and a saw blade (18) capable of being driven by the motor, and that includes a handle, whereby the saw assembly (12) is pivotably supported relative to a footplate (22) such that it can be adjusted between a minimum and maximum cutting depth, is protected against kickback by the fact that, during sawing, the saw assembly (12) is decoupled from handling forces acting on the saw blade (18), in particular from the handle (24).Type: GrantFiled: July 25, 2003Date of Patent: July 12, 2011Assignee: Robert Bosch GmbHInventors: Wolfgang Fuchs, Eduard Gansel, Heiko Roehm

Patent number: 7131899Abstract: A manual grinding tool, in particular an oscillating sander (10), with a housing (12) and an abrasive sheet carrier (14), against the working surface (15) of which an installable abrasive sheet (16; 150) rests, whereby said abrasive sheet is installed using clamping means (20, 23; 360, 500) which clamp opposite abrasive sheet ends (17, 19; 155) to the abrasive sheet carrier (14), is made easier to operate and handle because it is lighterweight and more effective by the fact that the clamping means (20, 23; 350, 500), together with an abrasive sheet end (17; 155) clamped thereto, are capable of being moved away from the diametrically opposed abrasive sheet end (19; 155) which is also clamped thereto, so that said abrasive sheet is locked under tensile stress, whereby the clamping means are composed of resilient material.Type: GrantFiled: February 10, 2003Date of Patent: November 7, 2006Assignee: Robert Bosch GmbHInventors: Eduard Gansel, Monika Renner

Patent number: 6393701Abstract: An electrical manual power saw includes a machine housing that has a housing shaft and a housing head (102) holding an interchangeable tool, and an electrical drive for driving the tool in an oscillating reciprocating motion. The housing shaft, for the sake of attaining an ergonomically defined gripping position in the vicinity of an on/off switch, has a rod-like shape, and in the transition region between the rod-shaped housing shaft and the housing head, a construction is provided. The on/off switch is disposed laterally offset on the housing head, below the axis of the shaft in such a way that when the constriction is grasped by a hand of a user the thumb of the grasping hand rests on its actuation knob.Type: GrantFiled: August 6, 1999Date of Patent: May 28, 2002Assignee: Robert Bosch GmbHInventors: Wolfgang Fuchs, Eduard Gansel, Uwe Engelfried

Patent number: 5570511Abstract: A hand circular saw comprises a swinging protective hood, a housing which carries a saw shaft axis and a saw blade held rotatable about the saw blade axis, a base plate, the housing being arranged independently turnably relative to the base plate around two further axes extending substantially perpendicular to one another, a first of the further axes being parallel to the saw shaft axis for guiding a turning movement for adjusting a cutting depth and is adjustable on a cutting depth guiding bracket with a scale, while a second of the further axes extends both parallel to the base plate and also parallel to the saw blade for guiding a turning movement for adjusting a miter angle, the cutting depth guiding bracket having an angle-profile shaped cross-section and having at least one leg which is formed as a sliding guide supporting the housing in each cutting depth position.Type: GrantFiled: January 20, 1995Date of Patent: November 5, 1996Assignee: Robert Bosch GmbHInventors: Doris Reich, Rainer Schilling, Wolfgang Fuchs, Eduard Gansel, Karl-Heinz Braunbach, Heribert Schramm, David Matzo

Patent number: 5381602Abstract: An electric motor operated hand circular saw has a base plate, a motor housing turnable relative to the base plate, an electric motor accommodated in the motor housing and having a drive shaft, a circular saw blade arranged on the drive shaft of the electric motor, and a pre-slitting abutment for adjusting a pre-slitting position of the saw blade in which the saw blade penetrates into a surface of a workpiece to be sawed by a limited pre-slitting depth.Type: GrantFiled: October 8, 1993Date of Patent: January 17, 1995Assignee: Robert Bosch GmbHInventors: David Matzo, Eduard Gansel, Heribert Schramm

Patent number: 5146682Abstract: A hand-held circular saw is designed so that a fan exhaust air from a fan wheel is introduced into a sawdust duct along the shortest path in a duct arranged inside a gearing housing, in order to reinforce a conveying of saw dust in the sawdust duct. The fan air is fed parallel to the movement direction of the sawdust, effects a vacuum in the sawdust duct and prevents stoppage of the duct.Type: GrantFiled: May 31, 1991Date of Patent: September 15, 1992Assignee: Robert Bosch GmbHInventors: Hans Blochle, Rainer Schilling, Martin Kummer, Eduard Gansel, Heribert Schramm, Helmut Eblen, Joachim Muller

Patent number: 4564181Abstract: A bench includes a rigid frame and a work board pivotable to and away from the frame. The work board can be brought into a rest position and into a plurality of operating positions and can be in at least two operating positions supported by an arm movably supported on the frame. The arm is pivotable with respect to the frame in a horizontal plane. The arm can carry at its free end a clamping device. The structure of the bench increases a range of clamping a work piece on the bench over the length of the work board.Type: GrantFiled: July 14, 1983Date of Patent: January 14, 1986Assignee: Robert Bosch GmbHInventors: Eduard Gansel, Gunter Schaal, Helmut Schneider, Heribert Schramm, Eberhard Seidel, Gunter Zilly
