    : Device intended for rotatable control of rig for felling machine of type grass trimmers and clearing saws, designed with one or two knobs for control of rig with associated degree instructions for different working angles. The above-mentioned device entails an improved ergonomic working method and prevents e.g. The device can be used either for an integrated type of rotatable rig or for a fully divisible telescopic type of rotatable rig, which can be varied in size and shape. The device design consists of an upper fixed rig and a lower rotatable rig, arranged as integrated or divisible. Common to both types of rigs is the circular rotatability of the axial extension of the inner rig according to the drawing and fastening for one or two locking knobs, via a continuous shaft through the fastenings according to the drawing. The upper and lower rigs of the device have integrated degree instructions around the periphery of the rig according to the drawing.

    Adaptable felling machine Description: Device intended for rotatable adjustment of the rig for felling machines such as grass trimmers and clearing saws, designed with one or two knobs for adjusting the rig with associated degree instructions for different working angles.
    The above-mentioned device entails an improved ergonomic working method and prevents e.g. back problems that are avoided by the stated device. The device can be used either for an integrated type of rotatable rig or for a completely divisible telescopic type of rotatable rig, which can be varied in size and shape.
    The device design consists of an upper fixed rig and a lower rotatable rig, arranged as integrated or divisible.
    Common to both types of rigs is the circular rotatability internally of the rig's axial extension according to the drawing and fastening for one or two locking knobs, via a continuous shaft through the fasteners according to the drawing.
    The upper and lower rigs of the device have integrated degree instructions around the periphery of the rig according to the drawing.
    Said device is designed so that the lower rig allows 360 degrees of rotatability internally and externally around the axial position of the upper rig and the possibility of being able to angle the lower rig of the device with a simple hand grip without removing the sling.

    Claims (1)
    [1]
    534 955 Claim 1 Device for a rotatable rig (2) for a felling machine of the type grass trimmer and clearing saw (1) consisting of an upper rig which is integrated with a motor and a lower rig which is rotatable relative to the upper one and which the felling device is characterized in that the upper and lower rigs have degree directions (4) around the periphery of each rig and that the upper rig has a milled groove and a locking knob (3) at its end facing the lower rig so that the lower rig can be locked in a selectable angular position. Claim 2 Device intended for rigs for grass trimmers and clearing saws according to claim 1, characterized in that the lower rig allows 360 degrees of rotatability. Claim 3 Device intended for rigs for grass trimmers and clearing saws according to claim 1, characterized by a completely divisible telescopic rotatable rig. Claim 4 Device intended for rigs for grass trimmers and clearing saws according to claim 1, characterized in that locking of the lower adjustable rig is regulated with a one-handle control.
