Embodiment Construction

[0113] The exemplary embodiment relates to a hand-held power tool 10 in the form of a grinding machine, wherein, with respect to some aspects of the following description, however, other embodiments of the hand-held power tool are also possible, such as milling machines, polishing machines or the like thing. Furthermore, in the case of this embodiment an elongated handle element is shown, which can be shorter or longer altogether. The hand-held power tool according to the figures is advantageous for ceiling or wall machining. The hand-held power tool 10 according to the figures can also be referred to as a top grinder and / or a wall grinder. Aspects of the following embodiments do not necessarily only relate to grinding, polishing or milling machines, but can also be applied in the context of other hand-held power tools.

[0114] The hand-held power tool 10 has a machining head 11 , which is articulated on a handle element 12 by means of an articulation assembly 13 (albeit im...

Abstract

The invention relates to a hand-held machine tool (10) having a, in particular rod-shaped, handle element (12) for an operator to grasp and having a machining head (11), which is movably mounted on the handle element (12) by means of a joint assembly (13) and which has an electric drive motor (100) for driving a tool holder (19) for holding a machining tool (20), wherein a bottom side of the handle element (12) and a machining side of the machining head (11) face a workpiece (W) in a base position of the machining head (11), the joint assembly (13) is connected to the machining head (11) in anarticulated-connection region of the machining head (11), and a flexible suction hose for conducting a suction flow from the machining head (11) to the handle element (12) extends between the handleelement (12) and the machining head (11), which suction hose is fastened to an end region of the handle element (12) by means of a first hose end and to a suction connection (23) of the machining head(11) by means of a second hose end. According to the invention, the suction connection (23) is arranged between the end region of the handle element (12) and the articulated-connection region of themachining head (11) in the base position.

Description

technical field [0001] The invention relates to a hand-held power tool, in particular a grinding machine, with a particularly rod-shaped handle element for being held by an operator and is movably mounted on the handle element via a joint assembly machining head with an electric drive motor for driving the tool holder (Werkzeugaufnahme) for holding the machining tool, wherein in the basic position of the machining head the underside (Unterseite) of the handle element and the machining side of the machining head (Bearbeitungsseite) facing the workpiece, wherein the articulation assembly is connected to the processing head at the articulation area of ​​the processing head, wherein between the handle element and the processing head extends the suction flow (Saugstrom) from the processing head to the handle A flexible suction hose of the element is attached with a first hose end to the end region of the handle element and with a second hose end to the suction connection of the pro...
