Embodiment Construction

[0031] figure 1 A hedge trimmer 1' according to the prior art is shown. The hedge trimmer 1' has a rear handle 3 with a knife unit 9 on the side opposite the motor housing. A handle tube 4 is arranged on the side facing away from the rear handle 3 . A fuel tank 6 is provided between the rear handle 3 and the motor housing. The internal combustion engine of the hedge trimmer 1' faces the handle 3 with the crankcase, and faces the cutter device 9 with the cylinder. The distance a between the axis of rotation 24 of the crankshaft and the tool arrangement 9 is therefore relatively large.

[0032] exist figure 2 The shown hedge trimmer 1 according to the invention has a handle housing 2 on which a rear handle 3 and a handle tube 4 are arranged for guiding the hedge trimmer 1 . On the side of the handle housing 2 facing away from the rear handle 3 a knife device 9 projects forward. The tool device 9 has a guide 10 and two tool holders, wherein the first tool holder 11 can be ...

Abstract

The invention relates to a hedge trimmer 1, having a blade arrangement 9 with at least one cutter bar (11, 12). The utter bar (11, 12) is driven in a reciprocating manner by the drive motor via the gear mechanism 30 in a longitudinal direction. The blade arrangement includes a guide mechanism (10, 10') that extends over at least a part of the length of the cutter bar (11, 12). The cutter bar (11, 12) is longitudinally movably held on the guide mechanism (10, 10'). The guide mechanism (10, 10') is embodied as a molded part that includes a generally flat fastening portion 76 and a profiled guide portion 77. The cutter bar (11, 12) is supported on the guide portion 77, to achieve a high intensity when the weight is lighter.

Description

technical field [0001] The invention relates to a hedge trimmer of the type stated in the preamble of claim 1 . Background technique [0002] A hedge trimmer is known from DE 296 07 614 U1 with a knife arrangement which has two knife holders and is fixed longitudinally displaceably on a guide. This guide is formed in a U-shape. This U-shape is, for example, a cut bar. The construction of the guide means is therefore the same over the entire length. [0003] DE 151 103 B1 shows a hedge trimmer with a guide, which is likewise designed in a U-shape. The U shape is arranged such that the sides of the U point upwards. In the region of the housing of the hedge trimmer, the profile is split and straightened in the longitudinal direction to form two sides for fastening the profile to the housing of the hedge trimmer. [0004] The known guides have to be constructed from relatively strong and thus heavy profiles in order to have a sufficiently high strength over their entire len...
