Abstract
The invention concerns a telescopic device (1) comprising a first tubular element (3) and an extension member (2) displaceably arranged in an axial direction within the first tubular element (3), wherein a coupling member (16) is provided relatively displaceable to the extension member (2), between at least,—a first axial position wherein the extension member is displaceable within the first tubular element, and—a second axial position wherein the coupling member (16) engages between the extension member (2) and the first tubular element (3) limiting displacement in at least one longitudinal direction, where the coupling member (16) engages the interior of the first tubular element (3).
Claims20
A telescopic device comprising a first tubular element and an extension member displaceably arranged in an axial direction within the first tubular element, wherein a coupling member is provided relatively displaceable to the extension member, between at least,
- a first axial position wherein the extension member is displaceable within the first tubular element, and
- a second axial position wherein the coupling member engages between the extension member and the first tubular element limiting displacement in at least one longitudinal direction,
- where the coupling member engages the interior of the first tubular element;
- and
- wherein an outer surface of the coupling member is provided with treads.
