Definitions

  • the present invention relates to a support element for holding an object at a distance from an underlying surface, and in particular, for the support of raised surfaces.
  • Support elements for raised surfaces are commonly used for all types of applications such as raised roofs, terraces, or technical flooring for outdoor and indoor applications.
  • An example can be found in GB2378457 , in which a support element for floors, ceilings, and walls is disclosed.
  • DE2457743A1 shows an element showing the features of the preamble of claim 1. A common requirement when mounting such a raised surface is that a sufficiently level surface is obtained and a sufficiently stable surface.
  • shocks or vibrations to which the raised surface is exposed can to a greater or lesser degree be absorbed so that (i) the load on the raised surface as a result of these shocks and vibrations can be reduced, and/or (ii) these shocks and vibrations can be transmitted maximally unamplified, and preferably weakened, to the underlying surface.
  • the present invention relates to a support element for holding an object at a distance from an underlying surface according to the appended claim 1.
  • FIG. 1 to 8 illustrate different embodiments of a support element according to the present invention.
  • the support elements according to the present invention are generally suited for holding an object at a distance from an underlying surface.
  • these support elements are suitable for holding tiles, beams, battens, etc. for installing raised surfaces, such as an elevated roof terrace, elevated apartment terrace, elevated garden terrace, a stage, a raised technical floor for indoor or outdoor, a raised floor for indoor or outdoor, and the like.
  • the underlying surface means the ground, the roof, the platform, the conventional building floor between floors, or any other structure at a distance from which an object, and in particular, tiles, beams, battens, etc. for the installation of raised surfaces must be installed.
  • the advantage of the present invention is that the shock and/or vibration absorbing connecting piece provides the support element with increased shock and/or vibration absorption, such that shocks or vibrations can to a greater or lesser degree be absorbed so that (i) the load on the raised surface as a result of these shocks and vibrations can be reduced, and/or (ii) these shocks and vibrations can be transmitted maximally unamplified, and preferably weakened, to the underlying surface. Furthermore, by integrating the shock and/or vibration absorbing properties in a connection piece as part of the support element, instead of as a separate element between the base and underlying surface, the durability of the shock and/or vibration absorbing element is increased.
  • a shock and/or vibration absorbing support element takes less work and time than a conventional support element with unintegrated shock and/or vibration absorbing element to be installed separately.
  • shock and/or vibration absorbing connecting piece can also contribute to improved sound absorption due to vibration of the raised surface or of the underlying surface.
  • the base, the connecting pieces, and the support plate can be made of metal or of any synthetic material that is suitable for extrusion or injection moulding, such as polypropylene, polyethylene (low and high density), polyvinyl chloride, polystyrene, ethyl vinyl acetate, acrylonitrile-butadiene-styrene or polyolefin, or a combination thereof.
  • the shock and/or vibration absorbing material in the shock and/or vibration absorbing connecting piece can be any material that can to a greater or lesser degree absorb shocks and/or vibrations, such as, for example, rubber, foam, fibres, air cushions, chambers or cells with enclosed liquid or gas.
  • the shock and/or vibration absorbing connecting piece can consist of a frame that comprises a shock and/or vibration absorbing material (for example, a more or less supple casing filled with fibres or gas, cf. a tennis ball), or a frame that is at least partly enveloped by the shock and/or vibration absorbing material (for example, a metal or synthetic skeleton enveloped by rubber or foam).
  • the shock and/or vibration absorbing connecting piece can preferably also consist completely of shock and/or vibration absorbing material. It can be made of any shock and/or vibration absorbing synthetic material which is suitable for extrusion or injection moulding, such as polystyrene, polyurethane, polyester, polyethylene, etc., or it may be made of rubber, synthetic or natural, and preferably recycled rubber, or a combination of rubber and a synthetic material. In the case of rubber, the shock and/or vibration absorbing connecting piece can be made by compression moulding of rubber (whether recycled or granulated) and a polymer, for example, polyurethane.
  • the shock and/or vibration absorbing connecting piece should preferably have a compression of just a few millimetres, less than 5 mm, or even less than 3 mm, at a load which is common for all kinds of applications such as elevated roofs, terraces, or technical flooring for outdoor and indoor applications, and this depending on the chosen shock and/or vibration absorbing material.
  • the shock and/or vibration absorbing material can be chosen according to the maximum desired or permitted compression set (which is a measure of the permanent deformation when a compressive force is removed) according to standard ASTM D395, the foregoing according to the shock and/or vibration absorbing capacity of the connecting piece.
  • the shock and/or vibration absorbing connecting piece can be provided with means allowing it to be attached to the underlying and/or overlying connecting pieces, or in the absence of multiple connecting pieces, to the base and/or the support plate, for example, click systems or snap-fit clips.
  • the shock and/or vibration absorbing connecting piece can also be attached by means of gluing or welding.
  • the shock and/or vibration absorbing connecting piece can have a geometry that engages the underlying and/or overlying connecting pieces, if any, or in the absence of multiple connecting pieces, the base and/or the support plate.
  • the aforementioned geometry can, for example, be a raised edge at the periphery, such that the shock and/or vibration absorbing connecting piece cannot slide or be pressed out of the support element.
  • the geometry can also exhibit a relief on at least one side parallel with the underlying surface, having one or more projections and/or one or more cavities, which fit into a complementary relief of an overlying or underlying connecting piece, or in the absence of multiple connecting pieces, into a complementary relief on the base and/or the support plate.
  • FIG. 1 illustrates such a shock and/or vibration absorbing connecting piece with a pronounced relief that engages and/or is complementary with other parts of the support element, the foregoing in combination with snap-fit clips (x and x').
  • FIG. 2 and 3 illustrate two shock and/or vibration absorbing connecting pieces as described in the previous section, with different height, such that the height of the support element can be changed according to the desired application, by choosing a different height of shock and/or vibration absorbing connecting piece.
  • the one or more stackable connecting pieces including the shock and/or vibration absorbing connecting piece, exhibit a relief parallel to the underlying surface on both sides, having one or more projections and/or one or more cavities allowing several connecting pieces to be stacked such that the projecting portions of one connecting piece fit into the cavities of an overlying or underlying connecting piece.
  • An advantage of the invention is that the use of connecting pieces with a relief that allow different connecting pieces to fit on each other provides increased stability because the connecting pieces cannot slide out of each other due to the relief, which is particularly important for the shock and/or vibration absorbing connecting piece since this will tend to be pushed out of the support element by compression.
  • a second advantage is that such relief is a passive and therefore durable system to link connecting pieces to each other.
  • a third advantage is that the connecting pieces provide increased height adjustability such that applications where relatively large irregularities in the underlying surface need to be accommodated and/or where the distance between the raised surface and the underlying surface is relatively large are among the possibilities.
  • the relief of one or more projections and/or one or more cavities can comprise any combination of projections and/or cavities.
  • the relief on both sides of the connecting piece parallel with the underlying surface can be identical or can be different.
  • the support element is characterised by connecting pieces, including the shock and/or vibration absorbing connecting piece, with a relief on one side, parallel with the underlying surface, which is complementary to the relief on the opposite side.
  • a 'complementary relief' means that the relief on one side parallel to the underlying surface would theoretically fit on the relief on the opposite side parallel to the underlying surface. In this way, any connecting piece will fit on any other connecting piece, and connecting pieces can be exchanged with connecting pieces with a different height.
  • the support element can therefore be built up with exchangeable connecting pieces of different heights depending on the desired distance between the underlying surface and the object which is to be supported.
  • the one or more projections and/or one or more cavities can have any form.
  • the one or more projections (5) in the relief taper towards their free end, and the cavities (6) are defined by side walls and a base, the side walls of a cavity tapering towards the base.
  • the protrusions are therefore mastaba-shaped or even pyramid-shaped, while the cavities are in the form of an inverted mastaba or even an inverted pyramid.
  • each of the connecting pieces including the shock and/or vibration absorbing connecting piece, include one projection that is carried out annularly in the vicinity of the outer circumference of one side parallel with the underlying surface, and includes one cavity that is carried out annularly in the vicinity of the outer circumference of the opposite side parallel with the underlying surface.
  • the projection is disc-shaped, and the cavity is also disc-shaped.
  • the connecting pieces can be provided with means allowing the connecting pieces to be interconnected, for example, by means of click systems or snap-fit clips.
  • Each connecting piece can have a height, measured in the vertical direction of the upright support element, between 5 and 150 mm, preferably 15 mm, 50 mm and 100 mm.
  • the base (1) of the support element includes a disc-shaped cavity in which a ring-shaped element (7) with internal screw thread fits engaging with a control piece (8) with corresponding external screw thread, the control piece exhibiting a relief on the highest side parallel with the underlying surface of one or more projections and/or one or more cavities complementary to the relief of a connecting piece of the one or more connecting pieces (see circle).
  • the ring-shaped element consequently enters the disc-shaped cavity of the base.
  • the control piece is fastened by screwing it into the internal screw thread of the ring-shaped element.
  • a support element according to the present invention provides stepless height control which, in combination with the stackable connecting pieces (3), can bridge a very large difference in height.
  • the screw thread of the control piece has such a length, measured in the vertical direction of the upright support element, that it can bridge a difference in height which is at least equal to the height of the connecting piece with the lowest height among the connecting pieces.
  • the connecting piece with the lowest height has a height of 50 mm
  • the screw thread of the control piece must be able to bridge at least 50 mm, so that the support element obtains a stepless height control from 0 to 150 mm depending on whether no, one or two connecting pieces of 50 mm are used.
  • FIG. 8 shows a support element according to the present invention that can hold an object at a distance of between 70 and 327 mm from an underlying surface, the foregoing being infinitely variable if use is made of a circular element (7) and a control piece (8) with screw thread of 57 mm in height and provided the connecting pieces of 50 mm (3') and 100 mm (3") in height are used correctly.
  • the underside of the support plate has a relief complementary to the relief of the one or more connecting pieces such that the support plate can also be placed on the intermediate piece in a stable and durable manner.
  • the highest side of the control piece parallel to the underlying surface and viewed according to the vertical direction of the upright support element can possess a relief complementary to the relief of the one or more connecting pieces such that the one or more connecting pieces can be placed on the control piece in a stable and durable manner.
  • control piece can be provided with means which make it possible to fix the lower connecting piece to the control piece, for example, by means of click systems or snap-fit clips.
  • the ring-shaped element and the control piece may be made of any synthetic material that is suitable for extrusion or injection moulding, or of metal.
