Definitions
- the present invention relates to a riser pipe with floating gully covering comprising a covering rim connected at a socket to the riser pipe.
- the invention relates to a riser pipe with a floating gully covering of the kind referred to above wherein there is provided on the outside of the riser pipe a circumferential spherically curved bulge having the center of curvature on the center axis of the riser pipe, and there is provided on the inside of the socket an annular concavity adapted to the spherical curvature of the bulge, said concavity bearing against the bulge maintaining the riser pipe and the socket in mutual engagement allowing the gully covering to be universally tilted in relation to the riser pipe.
- the connection between the riser pipe and the covering rim is formed by a ball joint which allows the gully covering to be angled in relation to the telescope pipe such that the covering can be inclined in order to be adapted to existing slope of the ground surface.
- SE-B-398 904 discloses a riser pipe with a floating gully covering, constructed in said manner, the pipe wall and the socket being curved to form matching spherical surfaces.
- this prior art embodiment is difficult to manufacture because one of the two elements forming the ball joint - the riser pipe or the socket of the curved - in the manufacture before the covered shape is imparted thereto has to be passed into or over the other element in order then to be curved.
- This method of manufacture is complicated and cumbersome.
- one element, the riser pipe or the socket can be slotted so that the elements can be pulled together by the slotted element yielding resiliently, but also this involves a cumbersome method of manufacture.
- the object of the invention is to simplify considerably the manufacture of a riser pipe with a floating gully covering of the kind referred to herein, and this object is achieved by providing a riser pipe with a floating gully covering of said kind having the characterizing features of claim 1.
- a pipe 10 which can be assumed to be made of plastics and can form the upper portion of an underground telescopic riser pipe.
- a gully covering is provided which can be made of cast iron or plastics and comprises a covering rim 11 which should be flush e.g. with the surface of a roadway and is integral with a depending connection socket 12.
- the gully covering also comprises a gully cover 13 supported by a shoulder 14 in the rim. The upper surface of the cover is flush with the upper surface of the rim.
- the pipe 10 at the upper end thereof is shaped to form a spherically curved outside surface 15 the center of curvature of which being located on the center axis of the pipe. Centrally of said spherically curved surface there is formed an annular rib 16.
- a shallow annular groove is provided in the inner side of the socket 12 said groove having a spherically curved bottom surface and the center of curvature thereof being located on the center axis of the socket.
- a through passage 18 joining said annular groove tangentially as shown in FIG 3.
- an elastically flexible strip element 19 preferably extruded of suitable plastics having good bearing properties has been inserted from the outside into the groove 17 through the passage 18 in order to interconnect the covering and the pipe.
- Said element has a smooth outside surface and this surface preferably is plane initially.
- the surface has adjusted to the curved bottom of the groove so that the element is curved transversally along the bottom.
- the element 19 adjacent the longitudinal edges thereof has two mutually spaced ribs 20 at each side of the annular rib 16, the annular rib 16 and the ribs 20 having such height that the element and the pipe interengage at these ribs.
- the gully covering 11 and the pipe 10 are effectively interlocked axially, the gully covering being easily rotated and tilted universally in relation to the pipe to allow adjustment of the position of the gully covering to existing slope of the ground surface.
- a ball joint connection beween the covering rim and the pipe.
- a spherical surface can be formed on the pipe by a simple working operation.
- the provision of an inside annular groove in the socket of the gully covering involves no difficulties.
- the element 19 can be extruded and, thus, also this element can be manufactured by a simple method of manufacture.
- the gully covering and the pipe are interconnected by the element 19 being pushed into the groove 17 through the passage 18, and also this working operation is not complicated.
- Suitable materials for the element 19 is softened PCV and hard rubber.
- the spherical surface on the pipe 10 in the simplest way is provided by shaping the pipe but it is of course also possible to mount on the cylindrical pipe a ring having a cylindral inside surface and a spherically curved outside surface. It is not necessary that the groove 17 is continuous overthe entire circumference of the socket. This groove can be limited to the peripherally spaced raised portions on the inside surface of the socket.
- the element 19 and the surface 15 interengage at the ribs 16 and 20 but the element and the surface can also interengage directly.
- the ribs limit tilting of the covering rim and prevent the rim from being pulled off the pipe by the rim being tilted.
