  • Patent number: 8776656
    Abstract: A circular and miter box saw has a contact table containing a support device that can be pivoted about a pivoting axis relative to the contact table and a base plate. The support device is pivot-supported on the base plate. The saw further has a miter box arm that can be pivoted about the pivoting axis, and a sawing device being disposed on the miter box arm, or above the contact table, respectively, wherein the sawing device can be displaced by a gliding guide device. The circular and miter box saw has a high cutting quality and a safe work piece contact surface and is characterized in that the gliding guide device is provided substantially below the base plate.

  • Patent number: 8752644
    Abstract: An electric tool, particularly a saw, has a connecting region and an actuating handle. The actuating handle is pivotally arranged on the connecting region, wherein the actuating handle can be pivoted into a number of pivoted positions and the actuating handle has at least one actuating switch for the electrical actuation of the electric tool. An uncomfortable position of the hand during actuation of the actuating handle is avoided and a high degree of comfort is achieved by the connecting region and the actuating handle being connected to each other by way of an articulated connection and by the articulated connection having a bearing lug and a handle pivot pin in engagement with the bearing lug.

  • Publication number: 20120067185
    Abstract: A circular cross-cut and miter saw has a supporting table and a sawing device, which is pivotable about a cross-cutting axis and has a saw blade and a movable swing guard. During a cross-cutting movement of the sawing device, a swivel mechanism produces a pivoting and/or swiveling movement of the swing guard such that the swing guard can be at least partly opened by swinging the sawing device down and closed by swinging the sawing device up. Uncomfortable and dangerous handling of the swing guard during the cross-cutting movement is avoided by a locking element of the swivel mechanism disposed such that the swing guard can be opened still further, even completely, by hand or by a workpiece to be cut, if either the locking element has been actuated or the cross-cutting movement has already been at least partially carried out.
