DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
(13) Initially, reference is made to FIG. 1 and the basic structure of a small playing field according to the present invention is explained based on this. This has, for example, a roughly rectangular ground layout with two parallel longitudinal sides 10, 11, two parallel transverse sides 12, 13, which connect the two longitudinal sides to one another, and four corner posts 14, each in the corner regions, where each the longitudinal sides 10 and 11 meet the transverse sides 12, 13. The playing field boundary for the small playing field is modular and consists of interconnected fence elements 16 on the two longitudinal sides 10, 11 and on the two transverse sides 12, 13 in the form of plates or panels and vertical posts 15, to which these fence elements 16 are attached.
(14) As can be seen in FIG. 2, which shows a section, for example, of one of the longitudinal sides of the playing field boundary, the individual panels 16 of the fence elements are bordered on the top by approximately horizontally running handrail profiles 17, wherein butt connectors 18 are respectively provided, which each overarch two adjacent handrail profiles 17 across a part of their length at the region where they meet, wherein the butt connectors 18 each connect two adjacent fence elements 16 among one another and wherein fastening devices 19 extending in the transverse direction to the handrails are provided in order to connect one butt connector 18 each to two adjacent handrail profiles 17 respectively. It can be seen in FIG. 2 that, in addition to the handrail profiles 17 in the lower regions of the panels 16, footpath profiles 20 are provided, which extend in the longitudinal direction of the playing field boundary, wherein, in the connecting region of two adjacent fence elements 16, butt connectors 21, which are open towards the top and have a U-shaped cross-sectional profile, are provided for the footpath profiles 20, wherein these connectors 21 can also be connected to the footpath profiles 20 via fastening elements, which are still be explained further below.
(15) Furthermore, it can be seen in FIG. 2 that, at distance to the inner handrail profiles 17, which are facing the playing field, in addition, parallel outer handrail profiles 22 are arranged, which are also connected to one another via butt connectors 23 in the longitudinal direction, wherein, profile-like connectors 24 running at right angle to the inner and the outer handrail profiles connect the butt connectors 18 for the inner and those 23 for the outer handrail profiles 22 to one another, wherein the butt connectors 23 for the outer handrail profiles 22 can preferably be connected to the outer handrail profiles via pins or bolts, which each engage into corresponding bore holes of the two adjacent handrail profiles 22, and/or via horizontal screw connections. The connectors 24 are used to receive the vertical forces acting on the outer handrail 22, for example, due to leaning or even sitting spectators, wherein, preferably, a reinforcement blade 26, which has a standing surface at its underside, is present that protrudes outwardly at a right angle starting from the vertical post 25 located where two adjacent panels 16 meet.
(16) More detailed details concerning the vertical posts 15 and the outwardly protruding reinforcement blades 26 are derived from the illustration in accordance with FIG. 8, to which reference is made below. Some of the vertical posts 15, which lie on the longitudinal sides and optionally also on the transverse sides each between the corner posts 14, are designed as intermediate posts and comprise, on the one hand, a vertically orientated rectangular post profile 27 and, additionally, two metal sheets 28 running vertically and orientated in the region of the butt connectors in the longitudinal direction of the playing field boundary and a vertically orientated U-profile 29, which is arranged between these metal sheets 28 and connected to these metal sheets, wherein only the two metal sheets 28 extend downwards in the vertical direction to the lower butt connectors 21. The reinforcement blades 26 have a lower standing region 26 a, which can also be recognized in the horizontal section view A-A in accordance with FIG. 9, in which one also sees the structure of the post with post profile 27, metal sheets 28 and a U-profile 29. In addition, in FIG. 9, the lower upwardly open U-shaped butt connector 21 for the footpath profiles 20 can be recognized.
(17) In the following, reference is now made to the FIGS. 3 to 5. FIG. 3 shows a side view of one of the upper butt connectors 18 for the handrail profiles 17 at an enlarged scale. In FIG. 4 shows a unit with a butt connector 18 for the inner handrail profile 17, a butt connector 23 for the outer handrail profile 22, and a connector 24, which connects these two in the transverse direction to the longitudinal extension of the playing field boundary, the panels and handrails. In FIG. 5, a top view of this unit is shown. As is shown in FIG. 4, the butt connectors 18 are U-profiles that are open downwards. Pins 30 or bolts integrated in the butt connectors 18 are provided as shearing/pressure elements, which each engage into corresponding bore holes of the two adjacent handrail profiles. These pins 30 or bolts can be welded into the butt connectors and the pins 30 or bolts can each be attached on the inner side and, in the mounted state, attached to an upper horizontal bar 18 a/23 a of these U-profiles 18/23 protruding downwards. The bore holes that receive the bolts or pins 30 of the butt connectors 18/23 can be incorporated into the upper horizontal wall of the rectangular profiles of the handrail profiles 17. By engaging into the respective bore holes of two adjacent handrail profiles 17, the latter can no longer shift in the longitudinal direction of the playing field boundary. In FIG. 4, the fastening devices 31 can also be recognized, which extend in the transverse direction to the longitudinal extension of the handrail profiles and via which the butt connectors 18 each connect two adjacent handrail profiles 18.
(18) As FIG. 5 shows, a butt connector 18 comprises, for example, four such adjacent pins 30, of which two are each beyond the centre (viewed in the longitudinal direction) of the butt connector 18 so that each of these pins 30 are assigned to one of the two handrail profiles 17 and each engage into its bore holes, because the two handrail profiles 17 to be connected to each other are, of course, overarched by the butt connector 18 in such a way that they meet approximately at its centre. As can be furthermore seen from FIG. 5, the butt connectors 23 arranged at a distance to the inner handrail profiles 17 for the parallel outer handrail profiles 22 are principally constructed in the same way as the butt connectors 18 for the inner handrail profiles 17 and similarly comprise, in the mounted state, pins or bolts orientated approximately vertically downwards, which each engage into corresponding bore holes of the two adjacent outer handrail profiles. In addition, the outer butt connectors 23 can also be connected to the outer handrail profiles via horizontal screw connections 31.
(19) In FIG. 8 it can furthermore be recognized that screws 33 are provided, which are vertically screwed into a bore hole of a head plate 34 of the posts and into a bore hole of the butt connector 18, wherein these screws 33 can also be recognized in FIGS. 3 and 4. These screws secure the U-shaped butt connectors 18 on the posts against falling off and being removed.
(20) In the following, reference is made to FIGS. 6 and 7, which, in each case, in the side view or in the top view, show a section of the outer handrail profiles 22, which runs, on the one hand, in the longitudinal direction of the longitudinal side 11 of the playing field boundary and which is then bluntly angled twice, thereby running towards the corner post 14 (see also FIG. 1) so that the outer handrail can be screwed on a lateral surface of the corner post 14 via a connecting plate 32 and fastening elements. Due to the doubly-blunt angling, the connecting plate 32 runs in a plane parallel to the longitudinal extension of the outer handrail profiles. In the top view on the entire playing field in accordance with FIG. 1, the angling in the corner region can also be recognized, through which the outer handrail profile 22 runs towards the corner post 14. This type of attachment of the outer handrail profile 22 via the connecting plate 32 to the corner post 14 also achieves a high level of stability in the corner region of the playing field boundary and a favourable force flow from the longitudinal side 11 to the transverse side 12 of the playing field boundary.
(21) In the following, reference is made to FIGS. 10 and 11 and, based on these, the geometric conditions is clarified once again in the region of one of the intermediate posts 15, wherein one recognizes in the enlarged perspective illustration in accordance with FIG. 11 how the post is connected to the lower butt connector 21. There, one recognizes the two metal sheets 28 and the adjacent rectangular posts 27; in FIG. 10, the U-profile 29 can also be seen, which extends between the two metal sheets 28 in the transverse direction. In FIG. 11, one can see the upwardly open U-profile of the butt connector 21 for the footpath profile and one can see that, in the U-bar, there are a total of four pins 30 approximately lying in a row, which protrude upwards so that they can engage into bore holes of the two adjacent footpath profiles 20, which connect them in the region where they meet.
