Electric hedge trimmer

The invention relates to a hedge trimmer with an electric one Drive, a first, firmly arranged on the housing handle with a holder and a »wide, bow-shaped between the knife and the electric motor Handle, from the dome via a rod a second in the housing lying holder can be actuated, whereby both holders have to be switched on in order to move the naval knife to move. The Heolceneohere can only run when each hand grabs one handle, so that a far-reaching security is achieved that not one Hand of the operator can get into the running knife. In a known embodiment, the is designed as a bracket Handle can be pivoted about an axis and at his

t

against a pivoting action that takes place is more frequent Switch switched on · Be bmm so etiadlg This bulb-shaped handle can be sucked into the motor binge, what can lead to early fatigue. Also becomes more common causes the device to switch off unintentionally, when the working position is leaning towards the handle difficult.

Per invention, the task is sugrunde, a Heokeneehere su eobaffen, with the hands of the Bedlewsngsaannes as well are tied when the hedge trimmer is put into operation becomes, but in which the Sobalterbedionung is essential simplified 1st and can be torgenomed without any effort.

To achieve this object, the invention provides that the "long handle also rigidly aa Gehäuee secured 1st and the fingers of the hand relatively movable lever is disposed below this handle it against the action of leather ■ which angslft a Ansät 'em linkage · Babel, the »wide · handle and the switching lever can be at least partially retracted into one another. In a particularly advantageous catfish, the wide handle has a recess into which the dowel-shaped holding lever fits. His cheap Saufon lets you see

After the invention we realized that the temple ends de · «riding handles · and the ironing wires of the Sohalt levers on the housing are roughly close to each other and the Shift lever is mounted in a bolt surrounded by a torsion spring with its strap ends, the torsion spring to push the swiveling lever away from the handle ouch. Bas seaweed that comes from a stored in the case If there is a bolt, a spring is placed near the outside pressed so that the switch is automatically in its Ausohaltstellung got. Even the holder on the first handle goes autotnatisoh in the exhibition as soon as the So hold button is released, so the hand the handle releases. The switch that can be operated by the gearshift lever is connected to the field winding of the electric motor, it sits inside the housing in a special insulating box.

Further details of the invention are based on the drawing, which represents an example of the shape of the guide, explained in more detail. Ss show:

The hedge trimmer has two handles 9,10, the hand-

10 is bow-shaped, it is with its bow ends rigidly attached to the housing 1.

According to the invention, a shift lever 13 is now provided, which is movable relative to the handle 10 against the action of a spring 14. This Sch?

formed, ale surrounds the bolt 15 and acts so that · they push away the holding lever 13 from the handle 10. Of the Handle 10 is provided with a recess 17 into which the switching lever 13 can be lowered.

In the housing 1 is now in a special insulating box 1Θ a second Sohalter 19 housed, the electrical with the field coil 20 of the electric motor 3 is connected. to its actuation is a rod 21, which consists of a bolt 22 in the sloped embodiment, which is mounted in the housing 1 so as to be longitudinally displaceable. This bolt 22 is under the influence of a spring 23, the seeks to push it out of the housing 1, so that the holding button 24- of the holding device 19 is also always automatic got into the exhibition. A shoulder 25 of the holding lever engages on the free end face of the bolt 22 on, which pushes the bolt 22 inwards as soon as the switch lever 13 with the fingers in the recess 17 of the handle 10 is pressed in and the switch 19 is switched on

When working, you must keep your hands on the handles 9 and 10 attack, and it must both the Sehaltknopf 12 of the switch 11 with the fingers of one hand as well the stop button 24 of the holder 19 over the bolt 22 and

The advantages obtained with the invention are particular that trots the use of a bow-shaped wide handle for easy handling of the Heoicensohere fatigue-free prattieeh in all situations Switch actuation is given, so seen overall an easier handling of the whole device and thus also results in greater security.
