English Abstract


ABSTRACT
The invention relates to a telescopic column pipe
to be located in the ground, wherein an upper pipe
element is provided with a top covering to be disposed
substantially at ground level, and is displaceably
received at a smooth portion thereof in a lower pipe
element. The upper pipe element has an outside screw
thread extending over at least part of the circumference
of side pipe element. By rotating the upper pipe element
this element can be moved up and down in relation to the
lower pipe element solely by the cooperation of the
screw thread with the surrounding ground material.


Claims

Note: Claims are shown in the official language in which they were submitted.


THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE PROPERTY
OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. Telescopic column pipe to be located in the
ground, comprising lower and upper pipe elements, the
upper pipe element of which has a thread over at least
part of the circumference thereof to be displaceable
axially in relation to the lower pipe element by a
rotational motion, c h a r a c t e r i z e d in that
the outside thread of the upper pipe element is limited
to a portion of said pipe element adjacent a top
covering provided at the upper end thereof to be located
substantially at ground level, the rest of the upper
pipe element having a smooth outside surface and being
inserted with the smooth portion into the lower pipe
element to be displaceable axially in relation to the
lower pipe element so that the upper pipe element can be
displace axially in relation to the lower pipe element
by the rotational motion solely by the engagement of the
thread in the surrounding ground material.
2. Telescopic column pipe as claimed in claim 1
wherein the thread extends around the circumference of
the upper pipe element.
3. Telescopic column pipe as claimed in claim 2
wherein the thread extends over substantially one turn
around the circumference of the upper pipe element,
beginning adjacent a rim forming part of the top
covering.
4. Telescopic column pipe as claimed in claim 1
wherein the thread forms a sharp peripheral edge.
