Definitions

  • the invention generally relates to the field of pillar systems, and more specifically to telescopic pillar systems acting as supports of wall panels on a ship or other offshore platforms.
  • partition walls to prevent or reduce view between balconies and hence improve privacy. This may be in buildings of different types, but also on e.g. passenger ships.
  • the partition walls may be mounted on fixed pillars or on fixed supports.
  • telescopic pillar systems may be used to improve flexibility in terms of tolerances and to allow modules which may fit to different applications.
  • a known type of a telescopic pillar system for example shown in WO 2019/142160 A1 and US3228646A , comprises a first and a second longitudinally extending member, wherein the two members are slidingly engaged such that the first member is inserted into the second member, thereby allowing a variable distance between the ends of the telescopic pillar.
  • the ends of such a telescopic pillar system typically comprise mounting plates which are fixedly arranged by e.g. welding, to the respective first and second members. This allows no flexibility in case the support surfaces should be provided with different angles. In fact, support surfaces with different angles are very common, especially on ship balconies. Also, it is very common that not only the angles but also the longitudinal distance varies between different balconies of the ship. It goes without saying that this complicates mounting but also the use of, or provision of any modular telescopic pillar systems for these types of applications.
  • Another object of the invention is to provide an improved resistance to fatigue caused by uncontrolled and constant movement of the installation during its lifetime.
  • Yet another object is to provide a telescopic pillar system that may be used no matter type of installation, i.e. no matter if it is land based or marine and no matter if the pillar system should be used for any add-ons such as partition walls.
  • a telescopic pillar system comprising a male rail portion having at least one protrusion and a female rail portion, said female rail portion having a longitudinal extension and a free end comprising an end plate, said end plate comprising at least one through-going opening having a cross-sectional profile as seen in a geometrical plane extending transverse to the longitudinal extension of the female rail portion, said cross-sectional profile being complementary to an outer cross-sectional profile of the at least one protrusion of the male rail portion, thereby allowing insertion of the at least one protrusion into said at least one through-going opening, wherein, in an inserted position, the male rail portion is allowed to be displaced along the longitudinal extension of the female rail portion, and allowed to be tilted in view of the geometrical plane extending transverse to the longitudinal extension of the female rail portion.
  • the longitudinal displacement and tilting is allowed during mounting of the telescopic pillar system between two supports, and also after mounting.
  • the latter is of importance to allow the installation to accommodate longitudinal and tilting movements during its lifetime.
  • the invention provides an enhanced telescopic pillar system allowed to be mounted between two separate supports, wherein a mounting of the telescopic pillar system is less sensitive not only in terms of a longitudinal separation between the two supports, but also in terms of the angle between the surfaces of the supports.
  • This effect may at least partly be achieved since the telescopic pillar system does not use any clamping means to longitudinally clamp the male rail portion and the female rail portion.
  • the male rail portion is longitudinally moveable relative to the female rail portion, before, during, and after mounting.
  • the tiltability of the male rail portion relative to the female rail portion may at least partly be achieved by the formation of a limited contact surface between the protruding portion of the male rail portion and the through-going opening of the end plate of the female rail portion.
  • the contact surface that is formed is substantially restricted to a portion of the material thickness of the circumferential edge which is defined by the through-going opening in the end plate of the female rail portion, which during a tilting of the male rail portion in view of the female rail portion comes in contact with the male rail portion.
  • a tiltability may be provided after mounting of the telescopic pillar system between two supports.
  • manufacturers do not have to individually adapt their production of telescopic pillar systems to each and every specific angle between the supports, thereby reducing time and cost.
  • the telescopic pillar system allows for longitudinally and tiltably flexible supports as the telescopic pillar system is not rigid, neither in the longitudinal nor along at least one angular extension. That is, provided the telescopic pillar system is to be mounted between two supports, e.g., a ceiling console and a floor, the longitudinal and transversal flexibility may allow the angle between the attachment plane of the ceiling console and the attachment plane of the floor to vary between different ceiling consoles. The flexibility of the telescopic pillar system may further allow mutual longitudinal and/or transversal movements between the supports.
  • Such a flexibility may thereby allow accommodation of the frequently occurring movement of, e.g., a ship hull, thereby preventing fatigue of such otherwise weak zones in vicinity of the connections between the attaching points of the telescopic pillar system and the supports.
  • respective portion of the male rail portion and the female rail portion may allow attachment of add-ons, such as partition walls.
  • male rail portion and the female rail portion may be substantially prevented from rotating relative to each other, at least in a plane transverse to the longitudinal extension. This applies even though the outer geometries should be circular. The rotation is prevented by through-going opening in the end plate of the female rail portion having a cross-sectional profile which is complementary to an outer cross-sectional profile of the at least one protrusion of the male rail portion.
  • the male rail portion may be allowed to be tilted about a tilting axis extending transverse to the longitudinal extension of the female rail portion, and wherein the outer cross-sectional profile of the at least one protrusion comprises at least one leg extending substantially orthogonally to said tilting axis.
  • Allowing the male rail portion to be substantially restricted to be tilted about a specific tilting axis enhances a transversely extended stability such that the telescopic pillar system may resist a significant load applied in the extension of the tilting axis.
  • the telescopic pillar system may thereby be load carrying against, e.g., sideways strong wind gusts.
  • the male rail portion will still have a certain flexibility in the extension along the tilting axis, thereby preventing fatigue of the articulating connection between the male rail portion and the female rail portion.
  • the outer cross-sectional profile of the at least one protrusion may have an H-profile, an I-profile or a T-profile.
  • An H-shaped cross-sectional profile has two legs interconnected by an intermediate web extending substantially perpendicular between the two legs.
  • the legs may preferably be hollow, which further enhances the strength of the protrusion.
  • the tilting axis in the context of the invention extends along the extension of web of the H-shaped profile as seen in a plane extending transverse to the longitudinal extension of the pillar system.
  • I- and T-shaped profile where the I-shaped profile has two legs and an intermediate web, thereby being substantially similar to the H-shaped profile.
  • the portions of the T-shaped profile are oriented such that the horizontal portion of the letter "T” constitutes the leg and the vertical portion constitutes the web.
  • the vertical portion of the letter “I” constitutes a web.
  • the tilting axis is substantially aligned along the web.
  • the legs of such profiles may substantially restrict rotation of the male rail portion relative to the female rail portion along the tilting axis. The legs further improve a torsional stiffness of the male rail portion.
  • the female rail portion may have a length as seen in the longitudinal extension being substantially longer than a length of the at least one protrusion of the male rail portion.
  • the length ratio between the female rail portion and the male rail portion may be set to allow a tilting angle of up to +/-45 degrees and more preferred up to +/-30 degrees.
  • the at least one through-going opening may comprise a bushing.
  • a bushing may prevent water from entering an interior of the female rail portion. Another advantage is that the bushing may contribute to dampen vibrations and thereby reduce unwanted noise that may occur in the interface between the male rail portion and the boundaries of the through-going opening. Another advantage is that the bushing may introduce additional, but controlled, friction between the male rail portion and the through-going opening of the female rail portion, thereby enhancing the longitudinal and transverse stability of the telescopic pillar system while at the same time maintaining its longitudinal and tiltable characteristics.
  • the bushing may be manufactured by rubber.
  • the rubber may be ethylene propylene diene monomer rubber (EPDM), which is a durable material that has elastic properties and absorption properties that are well suited for vibration damping, as well as having good sealing properties.
  • EPDM ethylene propylene diene monomer rubber
  • the rubber may be any other natural or synthetic rubber such as natural rubber (NR), styrene rubber (SBR), chloroprene rubber (CR), butyl rubber (IIR), silicone rubber (Q), or a mixture thereof, such as a mixture of natural rubber and styrene rubber (NR/SBR).
  • An exterior wall portion of the female rail portion may comprise at least one groove configured to allow direct or indirect support of a wall panel or bracket.
  • the female rail portion may be an extruded profile allowing grooves along at least one of its longitudinally extending sides.
  • a transverse cross-sectional profile of the female rail portion may comprise four sides, wherein the two opposing sides being perpendicular to the tilting axis comprise grooves configured to allow direct or indirect support of wall panels. Indirect support may be allowed by brackets which are used to mount the wall panel to the telescopic pillar system.
  • grooves may further comprise additional protrusions/grooves such that a complementary profile of a wall panel or a bracket may be slidingly engaged to the female rail portion, which may reduce mounting time as well as enhanced stability against, for instance substantially horizontal strong wind gusts that oftentimes occur, when mounted, transversely to the longitudinal extension of the female rail portion. Mounting of wall panels without using screws, or similar fastening means, may further allow an enhanced aesthetically pleasing impression.
  • the female rail portion may comprise, as seen in a direction transverse to the longitudinal extension of the female rail portion, two oppositely protruding flanges, and wherein said at least one protrusion of the male rail portion comprises a cut-out allowing the at least one protrusion to at least partly receive said oppositely protruding flanges.
  • the interior flanges serve as an interior reinforcement of the female rail portion to thereby improve its torsional stiffness. Thereby a slenderer pillar may be used. A drawback is however that such flanges also may restrict the available tilting angle of the male rail portion. By providing the at least one protrusion for the male rail portion with a cut-out to allow the at least one protrusion to straddle the flanges during tilting thereby not unduly affecting the available tilting angle.
  • the male rail portion may comprise a support plate, said support plate being configured to be attached to a support.
  • the female rail portion may comprise a support plate, said support plate being configured to be attached to a support.
  • the support plates may be tilted relative to the male rail portion and the female rail portion, respectively.
  • the support plate(s) are used to connect the pillar system between, e.g., a ceiling console and a floor.
  • the support plates may preferably be attached to the ceiling console and the floor by a plurality of bolts, thereby allowing for the telescopic pillar system to be rigidly clamped and thereby resist wind gusts and movement of the ship hull.
  • the support plate may be fixedly or articulately attached to the male rail portion and/or the female rail portion.
  • the support plate being fixedly attached to the male and/or female rail portions may allow the telescopic pillar system to be mounted in areas where it is desirable to have further rigidity both in the longitudinal extension and in the transverse extension. Allowing the support plates to be articulately attached to the male and/or the female rail portion allows enhanced flexibility in that the telescopic pillar system adjusts itself longitudinally and transversely to an oftentimes occurring movement of the ship hull. Thus, one or both ends of the telescopic pillar system may be provided with a fixed or articulately attached support plate.
  • the invention refers to the use of a telescopic pillar system for mounting a partition wall on a ship or on an offshore oil or gas platform.
  • the telescopic pillar system 100 may, as a non-limiting example, be configured to be mounted between a ship deck (not shown) and a ceiling console (not shown) or a cantilever (not shown) projecting from a wall or the like.
  • the ceiling console may be tilted relative to the ship deck.

  • the tilting is allowed not only in a condition when the telescopic pillar system is freestanding as is disclosed in Fig. 1 , but also in a condition when the telescopic pillar system is mounted between the ship deck and the ceiling console. Accordingly, the tilting and movability is allowed not only prior to, and during mounting, but also after mounting.

  • the male rail portion 10 comprises a support plate 11 which is configured to be directly or indirectly attached to a non-disclosed support by a plurality of bolts (not shown) extending in holes 18 in the support plate 11.

  • the minimal distance D between a first and a second bushing portion 69, separated by the interface region 68 may substantially be similar to the thickness T of the web 15 of the male rail potion 10.
  • Fig. 6 there is schematically disclosed an alternative embodiment of a protruding portion of a male rail portion having a T-shaped cross-sectional profile 80.
  • the definitions used in the description of the H-shaped cross-sectional profile are, unless nothing else is stated, reused when describing the T-shaped cross-sectional profile 80.
  • a T-shaped cross-sectional profile 80 may be described as a one-legged version of the above described H-shaped cross-sectional profile. Again, a web portion 82 extends substantially perpendicular to the extension of a leg portion 84.
  • the T-shaped cross-sectional profile 80 is disclosed as being solid. However, it is to be understood that it with remained function may be hollow.
  • the tilting axis 50 is configured to be substantially aligned with the web portion 82. The tilting axis 50 may substantially intersect the centre of mass of the T-shaped cross-sectional profile 80.
  • Fig. 7 there is schematically disclosed one embodiment of a protruding portion of the male rail portion 10 having an I-shaped cross-sectional profile 90.
  • the definitions that were used when describing the H-shaped cross-sectional profile are, unless nothing else is stated, reused when describing the I-shaped cross-sectional profile 70.
  • the I-shaped cross-sectional profile 90 basically differs from the above described H-shaped cross-sectional profile 70 in the height of the legs 94. It is to be understood that the leg 94 with remained function may be omitted in an I-shaped cross-sectional profile.
  • a web portion 92 extends substantially perpendicular to the extension of two substantially parallel leg portions 94.
  • the cross-sectional profile 90 is disclosed as being solid, although it with remained function may be hollow.
  • the tilting axis 50 is configured to be substantially aligned along the web portion 92.
  • the tilting axis 50 may substantially intersect the centre of mass of the I-shaped cross-sectional profile 90.
  • any cross-sectional profile having features similar to the embodiments described above may be configured to achieve the tilting function of the telescopic pillar system 100.
  • the protruding portion may have an H-shaped cross-sectional profile comprising an additional intermediate leg parallel to the legs 14.
  • Fig. 8 there is disclosed a schematic sideview of a freestanding telescopic pillar system 100 demonstrating how the involved parts may move relative to each other.
  • the pillar system 100 is illustrated as standing on a horizontal ground with the male and female rail portions 10;20 extending in the vertical direction.
  • the male rail portion 10 is disclosed as being substantially tiltable, see arrow A, relative to the female rail portion 20 about a tilting axis 50.
  • the tilting axis 50 is disclosed as extending along axis E y , i.e., along the viewing direction of Fig. 8 , i.e., into or outwards from the screen/paper.
  • the plane of the support plate 11 spans an angle ⁇ relative to a horizontal plane 54. In a preferred embodiment this angle ⁇ may lie within a range of angles from -45 to +45 degrees and more preferred -30 to +30 degrees.
  • the telescopic pillar system 100 may be configured to allow a larger angular range, for instance, using an end plate 40 having a wider through-going opening 42.
  • the angular range may also be changed by chamfering the edge portion 46 of the through-going opening 42 in the end plate 40 or by reducing the thickness of the end plate 40.
  • the male rail portion 10 may also, to a certain extent, be tiltable in an extension perpendicular to the tilting axis 50.
  • the male rail portion 10 When tilted, the male rail portion 10 is movable relative to the female rail portion 20 substantially along a longitudinal extension of the protruding portion 12; see arrow B.
  • the male rail portion 10 is displaceable along the longitudinal extension of the female rail portion 20, i.e. along axis E z , see arrow C.
  • the tiltability of the male rail portion 10 relative to the female rail portion 20 is at least partly achieved by the formation of a limited contacting surface between the protruding portion 12 of the male rail portion 10 and the through-going opening of the end plate 40 of the female rail portion 20.
  • the contacting surface that is formed is substantially restricted to a portion of the material thickness of the circumferential edge which is defined by the through-going opening 42 in the end plate 40 of the female rail portion, which during tilting of the male rail portion 10 in view of the female rail portion 20 comes in contact with the male rail portion 10.
  • a tiltability and longitudinal displacement is allowed after mounting of the telescopic pillar system between two supports.
  • the above-mentioned movability and tiltability is applicable both when the telescopic pillar system 100 is freestanding as of Fig. 8 , as well as when the telescopic pillar system is mounted between e.g. a ship deck and a ceiling console. Accordingly, the tilting and movability is allowed not only prior to, and during mounting, but also after mounting.
  • the telescopic pillar system 100 has been disclosed as being arranged with the male rail portion 10 received in the upper end of the female rail portion 20, it is to be understood that the male rail portion 10 with remained function may be arranged in the lower end of the female portion 20.
  • the female rail portion 20 may be provided with one male rail portion 10 in each end.
