Definitions

  • the invention relates to a play equipment or outdoor furniture system of the type specified in the preamble of claim 1.
  • the invention has for its object to provide a modular system, which is suitable for the composition of some children's play equipment into a play landscape, the post elements of the modular system to be anchored more resistant to rotting than wooden posts but also have properties that are comparable to those of the wooden posts.
  • the invention includes the knowledge that a post element having a concentric metal core and consisting of plastic and in particular of recycled plastic can be dimensioned and machined such that the properties of such post elements almost correspond to those of wooden posts, these post elements also having the disadvantageous rotting properties of Do not have wooden posts.
  • connection technology which stably joins the posts with connecting elements, connectors and the like, so that the post elements, despite the material composition, act as a homogeneous body and, as such, have a long service life and thus use time to reach.
  • Recycled plastic consists of plasticized thermoplastic materials and non-plasticized granular components such as polyamides, impurities and the like.
  • the production of this recycled plastic which consists of old plastics or waste plastics, requires only a fraction of the energy required for the production of new plastics.
  • the post element made of recycled plastic is preferably produced as a solid post, and then subsequently drilled out to accommodate the metal core to become.
  • the bore can either be adapted to the cross-sectional shape of the metal core or it can also, as in an advantageous development of the invention, be provided with radially inwardly projecting longitudinal ribs, the metal core of the post element, which is preferably designed as a round hollow tube and has an outer diameter, which corresponds to the diameter on which the end faces of the longitudinal ribs lie.
  • the metal core is only connected to the plastic casing at certain points, the greater expansion of the metal core than that of the plastic casing has less effect on the plastic casing due to temperature fluctuations, so that a plastic with high strength can be used without the risk that the Plastic coating is damaged if the temperature fluctuations are too high.
  • the additional elements to be connected such as beams, lateral infills, play platforms, catwalks or also play equipment are designed with areas that can be accommodated by the holding element.
  • an end element already described is preferably firmly connected to the metal core by welding or the like, so that tubular sections of the plastic sheathing and annular holding elements can be pushed onto them alternately.
  • an end element is then connected to the metal core (in particular by screwing on), so that a stable arrangement is created.
  • the end elements are connected to elements which can serve as ground anchors or form a post shoe or form connections for struts or roofing parts.
  • connecting and covering parts In order to protect the interior of the posts - and in particular the steel cores - from the weather, connecting and covering parts have edges that extend beyond the post end, which also increase the stability.
  • the system according to the invention is essentially based on the fact that connecting and terminating elements encompass the steel core, including the sheathing, if necessary under common traversing, in order to achieve stable mutual fastening thereon.
  • the lower end of the post element is preferably connected to an end element which is designed as a base plate and can be firmly anchored in a foundation block by means of screws and dowels.
  • the post element can be provided at the lower end with an end element designed as a cover cap with an enlarged cap cross section. The post element with the attached cover cap is inserted directly into the fresh concrete of the foundation and concreted in. The expanded cap cross-section of the cover cap increases the stability of the post element.
  • the end elements form connections for struts or roofing parts. If, for example, two post elements are connected to one another at their upper ends by means of a bent tube with a cross section which corresponds to the cross section of the post elements, the end elements of the two post elements are designed such that they can be screwed or plugged into the metal core of the post element and because of an external thread can be screwed into the end of the bent tube provided with an internal thread.
  • the ends of the bent tube are also formed such that they protrude beyond the post elements so that a gap between the post element and the tube with different shrinkage or expansion can not arise.
  • the upper end of the post element is preferably covered with an end element designed as a cap.
  • the cover cap can be directly inserted or screwed into a metal core with a round cross section. If the metal core either has a square cross section or if it is provided with an internal thread in the case of a round cross section, in a preferred embodiment of the cover cap according to the invention it is designed as a thin-walled hemispherical shell which can be inserted into the cavity of the metal core by means of a corresponding extension.
  • the edge of the cover cap extends far enough beyond the post element to always be able to cover a gap caused by different thermal expansions of the composite material.
  • the approach is preferably arranged centrally as a plastic tube on the inner wall of the cover cap.
  • the plastic sheathing and the metal core of the post element as well as the plastic tube of the cover cap either have bores already during manufacture or are subsequently provided with a bore passing through the post element.
  • a screw is screwed into this bore in order to achieve a firm connection between the covering cap and the post element, so that a post element is also clamped with such an end cap.
  • the load-bearing capacity of such a post element is considerably higher than that of a post element which consists exclusively of plastic or a non-clamped plastic sheathing on a metal core.
  • plastic / metal post element can be drilled through without any problems, bolts or screws can be inserted into bores which cross the plastic casing and metal core as a further possibility for fastening additional elements.
  • the construction system according to the invention all elements consist of plastic, in particular recycled plastic and / or metal. This complete replacement of wood leads to a saving of raw materials and high quality products, although some of them are made with recycled materials.
  • the design of the post element as a coated metal core ensures that the load-bearing capacity of the supporting parts of the construction system is given while at the same time improving the weather resistance of the individual elements.
  • the weight of a post element according to the invention is less than that of a wooden post, which has proven to be advantageous when transporting the elements to the installation site and during assembly.
  • the construction system according to the invention can therefore be used in many ways and allows universal design options and is also weather-resistant and easy to use.
  • the game landscape shown in FIG. 1 essentially consists of several vertical climbing steps 1, several play platforms 2, an add-on slide 3, a net bridge 4, an arch climbing net wall 5 with a slide rod 6, several plate infills 7 and a roofing 8.
  • a total of ten anchorable post elements 11 of different lengths are required for this playground landscape.
  • the surface of the post elements 11 consists of recycled plastic and is color and structurally matched to the assemblies 1 to 8, which are also predominantly made of recycled plastic, as is shown in more detail below with reference to the detailed drawings.
  • a metal core 12 in the form of a tube with a round cross section is one Recycled plastic sheath 14 surrounded, whose thickness is less than the outer diameter of the metal core 12.
  • the metal core 12 is longer than the plastic sheath 14 and provided with an external thread 13 at both ends.
  • Such a post element 11 of a construction system for assembling a play landscape is much more durable than a wooden post. There is no risk of rotting or rotting for the parts of the post element 11 that are anchored in the ground and are therefore difficult to control or repair. Stability and strength are achieved by the metal core 12 designed as a tube.
  • the plastic sheath 14 of the post 11 is provided with pigments for protection against the UV radiation from sunlight. The pigmentation and the machinability of the plastic casing 14 contribute to the fact that the post elements 11 can be structured like a wood.
  • Figure 3 shows a second embodiment of a post element 11 '.
  • the metal core 12 is in the form of a tube with a round cross section surrounded by a plastic sheath 14 ', which has radially inwardly projecting, in the longitudinal direction of the sheath 14' extending ribs 15 and which are dimensioned such that the outer diameter of the metal core 12 used Diameter on which the ribs 15 lie corresponds.
  • the ribs 15 and the tubular casing 14 ' are approximately of the same thickness.
  • FIG. 4 shows a sectional illustration of the screw connection of a post element 11 to a rod 16, which also consists of a metal core formed as a round tube 17 and surrounded by a plastic jacket 19.
  • the round tube 17 of the rod 16 is no longer than the plastic casing 19 and is provided with an internal thread 18 at both ends.
  • a rod 16 can be used, for example, as a supporting beam (FIG. 1) for a playing platform 2 between two post elements 11 or as a cross rod (FIG. 1) for forming a railing. Since the metal core 12 and the recycled plastic sheath 14 of the post element 11 can be drilled through, the use of screws 20 for fastening rods 16 to the post element 11 is possible.
  • the screw head 21 is preferably covered with a round cap 22 made of plastic. In addition to the aesthetic effect, extensive protection of the metal against moisture and other weather influences is also achieved.
  • a support sleeve 23 with a washer 24 that crosses the entire post element 11 is inserted into a corresponding transverse bore in the post element 11.
  • the inner diameter of the support sleeve 23 and the bore diameter of the washer 24 are slightly above the screw diameter, so that the screw 20 can be easily pushed through.
  • the support sleeve 23 is provided at one end with a narrow support collar 25. The distance between the collar 25 and the washer 24 corresponds exactly to the diameter of the post element 11 minus the depth of a depression 26 for the washer 24 and part of the rod 16.
  • the depression 26 ensures that the rod to be connected to the post element 11 16 frictionally abuts the post element 11. A further tightening of the screw 20 and thus a compression of the hollow post element 11 is not possible since the rod 16 presses against the washer 24, which in turn rests on the end of the support sleeve 23 opposite the end of the collar and consequently cannot retreat.
  • FIG. 6 shows a flange-like element designed as a cover cap 27.
  • the cover cap 27 serves as an upper end for a post element 11 with a round cross section and has a recess 28 on its underside, which is provided with a thread 29.
  • This cap 27 is on the protruding piece of screwed with an external thread 13 provided metal core 12.
  • the edge of the cap of the cap 27 can protrude sufficiently far beyond the post element 11 with an elongated web 30 in order to cover a gap caused by different thermal expansions of the composite material.
  • FIG. 7 shows a further variant of a flange-like element according to the invention designed as a cover cap 31.
  • the metal core 12 of the post element 11, which is designed as a tube with a round cross section, is provided at the ends with an internal thread 13 ', and does not protrude beyond the plastic sheath 14.
  • the cover cap 31 accordingly has an extension 32 with an external thread 33, which can be screwed into the metal core 12 with an internal thread 13 '.
  • This cover cap 31 is also connected to one end of a curved tube 9, in which the cover cap 31 has on its outer edge a thread 34 which can be screwed into the internal thread of the curved tube 9.
  • FIG. 8 shows two post elements 11 anchored in the ground, which are connected to one another at the upper ends by means of a curved tube 9 and have a lateral plate infill 7.
  • the lower external thread 13 having the end of the left post element 11 is connected to a flange-like element designed as a base plate 35.
  • the base plate 35 has a recess with an internal thread 36.
  • the base plate 35 is over screws 37 and dowels 38 firmly anchored in a foundation block 39.
  • the right-hand post element 11 has an internal thread 13 'at the lower end and is provided with a flange-like element designed as a cover cap 31', the design of which approximately corresponds to that of the cover cap 31 of FIG.
  • this cover cap 31 ' is designed with an enlarged cap cross section in order to increase the stability of the post element 11 to be anchored.
  • the post element 11 with the attached cap 31 ' is inserted directly into the foundation 40 to be created.
  • the upper ends of the post elements 11 each have a flange-like element which is designed as a cover cap 27 or 31. These cover caps have already been described in detail with reference to FIGS. 6 and 7.
  • the plastic sheath 14 of the post elements 11 is clamped between the upper and lower end-bounding, flange-like elements, which are designed as cover caps 27, 31, 31 'or as a base plate 35, so that the post elements 11 are very stable.
  • the curved tube 9 connected to the flange-like element designed as a cover cap 31 can either only serve as a connection between two post elements 11 or can also be used as part of a roof 8.
  • a region 8 formed between at least four post elements 11 is roofed over, two curved ones arranged adjacent to one another are bent Tubes 9 are connected to the longitudinal axes of the tubes 9 by means of a likewise bent plate element 10.
  • the plate element 10 forming the roof 8 is designed as a transparent cover, in particular made of Lexan.
  • the plastic sheathing 14 of the two post elements 11 is interrupted at several points and fastening elements 41 are arranged on the post elements 11 at these points.
