Definitions
- the invention relates to a telescopic well or column pipe comprising an outer tube and an insert tube axially displaceable in said outer tube, and a covering which receives in a socket the upper end of the insert tube and is rotatably connected therewith.
- the two tubes are made of plastic while the covering is made of cast iron or nodular iron.
- the covering can be rotated either for adjusting the position thereof in relation to a curb in case of a rectangular cover ⁇ ing, or for adjusting the covering to different le ⁇ vels in case of a covering which is provided with a helical flange embedded in surrounding packing ma ⁇ terial and providing axial displacement of the cover- ing when rotated.
- the purpose of the invention is to provide a ro ⁇ tary connection between the insert tube and the covering, which provides easy movement between plas ⁇ tic and iron and allows simple interconnection of said two elements and will be affected neither by existing load when the covering is run on, nor by the surrounding ground, said rotary connection being in working order also after having been used for a long time.
- the telescopic well or tele ⁇ scopic column pipe according to the invention has ob ⁇ tained the characteristics appearing from the claim.
- FIG 1 is a vertical cross-sectional view of a telescopic well of the invention
- FIG 2 is an enlarged view, partly an elevational view and partly a vertical cross-sectional view, of the covering and the insert tube as well as the rotary mounting arranged therebetween.
- FIG 3 is a fragmentary vertical cross-sectional view of the covering and the insert tube before they are put together to be interconnected
- FIG 4 is a fragmentary horizontal cross-sec ⁇ tional view of the socket of the covering and the insert tube.
- FIG 1 discloses a telescopic well having an outer tube A and an insert tube B, both made of plas ⁇ tic, and a well covering C.
- the covering comprises a covering frame 10 and a covering lid 11 which can both be made of cast iron or nodular iron, the covering lid being received in a recess in the covering frame.
- the covering frame forms a cylindrical socket 12 on the lower side thereof r and an inside shoulder 13 is provided there ⁇ in.
- the insert tube B which should be made of plas ⁇ tic material, is inserted at one end thereof into the socket 12 to engage the shoulder 13 at the end sur ⁇ face 14 of the tube.
- annular groove 15 is provided having semi-circular cross section
- a corresponding semi-circular annular groove 16 of the same dimension as the grove 15 is provided in the outer surface of the insert tube B, the two grooves being located so that they are in register when the insert tube is in ⁇ serted into the socket, to form together an annular groove having circular cross section.
- a through pas ⁇ sage 17 is provided in the socket 12, which has the same dimension and shape as the annular groove formed by the grooves 15 and 16, said passage joining tangentially said annular groove as will be seen from FIG 4.
- an extruded elastically flexible rib of a suit ⁇ able plastic material having good bearing properties is driven into the groove 15, 16.
- the rib has a smooth outside surface and the same cross-sectional form as the groove 15, 16 and should be dimensioned so that it fills completely said groove. The length thereof should be substantially equal to the circum ⁇ ference of the groove 15, 16.
- the covering frame 10 and the insert tube B are ef- fectively locked together axially by said rib.
- the rib allows the covering frame to be easily rotated in relation to the insert tube, which is an advantage when it is desired to adjust the position of the covering frame because in that case such adjustment can be easily done without the necessity of rotating the insert tube as a whole. Such rotation can be im ⁇ paired by the surrounding packing material pressing against the insert tube.
- the rib 18 When the covering is run on, the rib 18 will not be loaded because the load will be taken up by the engagement of the shoulder 13 with the annular end surface 14 of the insert tube. Thus, it is necessary for the rib 18 to take up such forces only to which it may be exposed when the insert tube is lifted at the covering frame for adjustment of the level of the covering frame. Such load is not particularly great.
- a gasket or a sealing compound can be provided as may be necessary in case of an access well for a remote heating system.
- the groove 16 can be provided by turning or form milling but it can also be provided by embossing, the insert pipe forming at the inside surface thereof a corresponding annular bead.
- the invention is not limited to an embodiment wherein the groove 15, 16 and the rib 18 have circu ⁇ lar cross-sectional shape.
- the groove can have an ⁇ other round cross-sectional shape and can be arranged to a major part in the socket 12 and to a minor part in the insert tube B, or vice versa.
- the rib should of course have a cross-sectional shape which is adapted to the shape of the groove.
