Handle Height Adjustment Device of Walk-Behind Power Tool, a Handle Assembly and a Walk-Behind Power Tool Comprising Such a Device

摘要

A handle height adjustment device of a handle assembly (2) of a walk-behind power tool (1). The handle height adjustment device (100) comprises a first toothed disk member (200), a second toothed disk member (300), and a disk interconnecting member. The disk interconnecting member (400) is arranged to be connected to the first toothed disk member (200) by means of a first interconnection mechanism (401), which first interconnection mechanism (401) inhibits relative movement between the disk interconnecting member (400) and the first toothed disk member (200) along an axis of rotation (500) of the handle height adjustment device (100), and which first interconnection mechanism (401) allows the disk interconnecting member to rotate relative the first toothed disk member about the axis of rotation (500). The disk interconnecting member (400) is arranged to be threadably connected to the second toothed disk member (300) by means of a second interconnection mechanism (402). The application also concerns a handle assembly and a walk-behind power tool comprising such a device.

主权项

1. A handle height adjustment device of a handle assembly of a walk behind power tool, the handle height adjustment device comprising:
a first toothed disk member arranged to be affixed to a first arm element of the handle assembly, a second toothed disk member arranged to be affixed to a second arm element of the handle assembly, a disk interconnecting member extending along an axis of rotation of the handle height adjustment device, the disk interconnecting member being operable to move the handle height adjustment device between a locked state in which the first and second toothed disk members intermesh, and an open state in which the first toothed disk member is rotatable relative to the second toothed disk member about the axis of rotation, wherein rotation of the disk interconnecting member in a first direction about the axis of rotation moves the handle height adjustment device towards the locked state, and wherein rotation of the disk interconnection member in a second direction, opposite to the first direction, moves the handle height adjustment device towards the open state,characterized in that
the disk interconnecting member is arranged to be connected to the first toothed disk member by means of a first interconnection mechanism, which first interconnection mechanism inhibits relative movement between the disk interconnecting member and the first toothed disk member along the axis of rotation, and which first interconnection mechanism allows the disk interconnecting member to rotate relative the first toothed disk member about the axis of rotation, and in that; the disk interconnecting member is arranged to be threadably connected to the second toothed disk member by means of a second interconnection mechanism.
