Problems solved by technology

[0004] Since the pins on the end sides of the extension rails are inserted only into the corresponding receiving holes, there is a danger that the connection between the guide rail and the extension rails will be damaged during the machining of the workpiece and the forces acting on the rails here. At least partly loosened and the extension rail is inclined and forms an angle relative to the guide rail, which can negatively affect the work result
[0005] Another disadvantage is the unergonomic handling of the guide rails and extension rails

Embodiment Construction

[0028] exist Figures 1 to 5 1 shows a guide rail 1 comprising three individual rail elements 2 which are each pivotally coupled to one another via end-side articulations 3 . exist figure 1 The guide rail 1 is shown in the folded state, which represents the non-functional position and in which the individual rail elements 2 are stacked directly on top of each other. The rail elements 2 are each constructed identically to each other and can be folded in a Z-shape. figure 1 The non-functional locations shown in the Figure 4 and 5 The functional positions shown in , in which the rail elements 2 are closed to one another at the ends and aligned coaxially with one another, result in a continuous contact surface for guiding the hand-held power tool. The boundary line between two rail elements 2 that abut one another seamlessly is designated with reference numeral 15 .

[0029] Each rail element 2 is provided with a stop 4 which is movably mounted on the upper side of one of th...

Abstract

The invention relates to a guide rail for a hand-held power tool, comprising at least two rail elements that can be joined to form a common guide rail, the rail elements being held together by a releasable connection. The connecting means comprise a hinge means by which the individual rail elements can be pivoted between a folded non-functional position and a functional position in a common plane.

Description

technical field [0001] The invention relates to a guide rail for a hand-held power tool. Background technique [0002] A guide rail of this type is known from DE 10 2004 017 420 A1, which is placed on the workpiece to be processed for the purpose of guiding an electric hand tool, such as a hand-held circular saw, router or jigsaw. The electric hand tool can be moved longitudinally along the guide grooves in the guide rail, thus making straight cuts. A slider slides in the guide groove of the guide rail, and the slider is connected with the hand-held power tool. [0003] In order to be able to perform longer cuts, the guide rail can be connected with an extension rail. In this case, the guide rail has on one end side a plurality of receiving holes into which pins arranged on the axial end side of the extension rail can be inserted. [0004] Since the pins on the end sides of the extension rails are inserted only into the corresponding receiving holes, there is a danger tha...
