5 Opfindelsen angâr en jord- eller gulvbelægning til tennisbaner og af den i kravets indledning angivne art.The invention relates to a ground or floor covering for tennis courts and of the nature specified in the preamble of the claim.
Underlag til dette og andre formâl er kendt fra det 10 svenske patentskrift 220.223, der angiver en be- lægning til boldbaner, opbygget af kvadratiske plastplader, der samles til en hel belægning.Substrates for this and other purposes are known from the Swedish patent specification 220,223, which specifies a coating for ball courts, made up of square plastic sheets which are assembled into a whole coating.
Selv om en belægning af den ovenfor angivne art op-15 fylder aile krav med hensyn til fjedrende egenskaber til boldspil, slidstyrke, gennemtrængelighed for vend, tilstrækkelig homogenitet over hele overfladen, lav vægt, ingen vedligeholdelse osv., lider den af den ulempe, at overfladen ved kontraktion pâ grund af 20 h0je eller lave omgivelsestemperaturer bliver ujævn, hvilket ofte gælder for udend0rs beliggende baner.Although a coating of the above type fulfills all requirements with regard to resilient properties for ball play, wear resistance, permeability of turn, sufficient homogeneity throughout the surface, low weight, no maintenance, etc., it suffers from the disadvantage that the surface due to contraction due to 20 high or low ambient temperatures becomes uneven, which often applies to outdoor courses.
Der dannes gruber og fremspring ved, at f.eks. pla-der, der udsættes for stærk solvarme, udvider sig i retning mod sâdanne plader, der ligger i skygge og 25 derfor ikke udvider sig, eller i hvert fald ikke i den udstrækning, som de solbelyste plader. De plader, der udvider sig mest, udsætter derfor de plader, der udvider sig mindst, for en meget stor kraft. Pâ grund af den store eller forholdsvis store friktionskraft, 30 som pladerne ud0ver mod underlaget, vil de plader, der udvider sig mindst, i stedet for at forskydes vandret i kraftens retning, forskydes opad, og derved vil dannes de ovennævnte fremspring og gruber, der umuligg0r enhver aktivitet pâ en sâdan belægning.Pits and projections are formed in that e.g. plates exposed to strong solar heat expand in the direction of such shadows and therefore do not expand, or at least not to the extent of the sunlit plates. The plates that expand the most, therefore, expose the plates that expand the least to a very large force. Due to the large or relatively large frictional force exerted by the plates against the substrate, the plates which extend least, instead of being horizontally displaced in the direction of the force, are displaced upwards, thereby forming the above projections and pits which makes any activity on such a coating impossible.

Det er opfindelsens formàl at anvise en belægning af den angivne art, hvor hvert element i en plade, lige-som hver enkelt plade, er i stand til at udvide sig eller trække sig sammen under vejrligets indflydelse 10 under ringe eller forholdsvis ringe pâvirkning af tilgrænsende elementer eller plader, samt at udforme pladerne eller elementernes anlægsorganer mod under-laget pâ en sâdan mâde, at specielt den uundgâelige ekspansionskraft pâvirker tilgrænsende plader pâ en 15 sâdan mâde, at hele enheder, spillebanen, bibringes en vandret forskydning, sâledes at de i indledningen nævnte gruber og fremspring ikke dannes. Belægningen kan herved anvendes uhindret af vejrligsbetingel-serne.It is an object of the invention to provide a coating of the kind specified, in which each element of a plate, like each plate, is capable of expanding or contracting under the influence of the weather under low or relatively minor influence of adjacent elements or plates, and to form the plates or elements' abutments against the substrate in such a way that especially the inevitable expansion force affects adjacent plates in such a way that whole units, the playing field, are imparted to a horizontal displacement, said pits and projections are not formed. The coating can thereby be used without hindrance by the weather conditions.

Dette opnâs ved at udforme belægningen if01ge opfin-delsen som nærmere angivet i kravets kendetegnende del.This is achieved by designing the coating according to the invention as specified in the characterizing part of the claim.
25 Ved denne udformning af en sâdan belægning opnâs, at de ribber, som skal overf0re belastningen til under-laget, og hvorpâ belægningen skal glide i tilfælde af en varmebevægelse, giver det st0rst mulige st0tte-areal og de st0rst mulige "glidesko", samtidig med, 30 at man undgâr gennemgâende ribber, der strækker sig ubrudt fra elementets ene kant til den anden og sâledes kan akkumulere f.eks. varmeudvidelse fra flere elementer. Ved netop at udf0re ribberne sâledes, at der er en afbrydelse af disse ved overgangen til et 35 nyt element, opnâs, at hvert element, nâr ribbens overside er udstyret med en opadvendende spalte, kan foretage en vis relativ bevægelse i forhold til de25 This design of such a coating achieves that the ribs which are to transfer the load to the substrate and on which the coating is to slide in the event of a heat movement provide the largest possible support area and the largest possible "sliding shoe", at the same time by avoiding through-going ribs that extend continuously from one edge to the other and thus can accumulate e.g. heat expansion from several elements. By precisely designing the ribs such that there is a break of these upon the transition to a new element, it is achieved that each element, when the top of the rib is equipped with an upwardly extending slot, can make some relative movement with respect to the ribs.

nærliggende elementer, uden at bevægelsen beh0ver sununere op over flere elementer. Det samme er tilfæl-det for selve fladen. Det m0nster, som ribberne i selve gangfladen har, giver den samme mulighed for at 5 undgâ gennemgàende ribber, som strækker sig fra den ene kant af et element til den anden og endog videre, hvorfor der i selve fladen heller ikke er sâ stor ri-siko for ophobning af spændinger, som ville f0re til en opadb0jning af fladen, nâr denne udsættes for 10 f.eks. solskin. Dette er ikke tilfældet med den fra svensk patent nr. 220.223 kendte belægning, hvor aile ribberne netop er gennemgàende pâ den mâde, at der i hvert element er et vinkelret kors, som forbinder elementets siders midtpunkter samt et gennemgàende 15 diagonalkors. Disse diagonalkors og vinkelrette midterribber gâr direkte over i naboelementernes tilsvarende strukturelementer, hvorfor der bliver mulighed for opsummering af store udvidelser, uden at disse kan udlignes pâ anden mâde end ved at give en 20 bevægelse vinkelret pâ belægningens plan. Dette und-gâs netop ved hjælp af belægningen if01ge op-findelsen, hvor overfladen dels gennemskæres af de opadvendende spalter, ligesom hverken ribber i selve fladens plan eller de ribber, hvorpâ fladen st0tter 25 pâ underlaget, er gennemgàende.nearby elements without the need to move more suns over several elements. The same is true of the surface itself. The pattern of the ribs in the walkway itself gives the same opportunity to avoid continuous ribs extending from one edge of an element to the other and even further, which is why there is not as great a ridge in the surface itself. risk of accumulation of tension which would lead to an upward bending of the surface when exposed to 10 e.g. sunshine. This is not the case with the coating known from Swedish Patent No. 220,223, in which all the ribs are precisely in the way that there is in each element a perpendicular cross connecting the center points of the element as well as a continuous diagonal cross. These diagonal crosses and perpendicular center ribs pass directly into the corresponding structural elements of the neighboring elements, which makes it possible to summarize large extensions without being able to offset them other than by giving a motion perpendicular to the plane of the coating. This is avoided precisely by means of the coating according to the invention, where the surface is partly intersected by the upwardly extending slots, just as neither ribs in the plane of the surface itself nor the ribs on which the surface supports 25 on the substrate are continuous.
I det f01gende skal opfindelsen forklares nærmere under henvisning til tegningen, der viser en udf0rel-sesform for en belægning if01ge opfindelsen, og hvor 30 fig. 1 viser en udf0relsesform for en plade til en belægning til tennisbaner if0lge opfindelsen, set fra siden, 35 fig, 2 viser den i fig. 1 viste plade set fra neden, fig. 3 viser dele af to indbyrdes forbundne plader.In the following, the invention will be explained in more detail with reference to the drawing, which shows an embodiment of a coating according to the invention, in which FIG. 1 is a side view of an embodiment of a tennis court covering sheet according to the invention; FIG. 2 is a side view of FIG. 1 from below; FIG. 3 shows portions of two interconnected plates.

Som det fremgâr af tegningen er hver plade opbygget af seksten ens, kvadratiske elementer 1. Hvert élément 1 har en overside med en plan overflade be-stâende af et antal ribber og mellemliggende âbninger 10 12 i et vist m0nster og med dimensionerne af ribber og âbninger tilpasset pladens aktuelle formâl, f.eks. tennis. Opfindelsen er ikke begrænset til særlige m0nstre for elementernes overside og heller ikke til, at elementerne har kvadratisk form.As can be seen from the drawing, each plate is made up of sixteen equal square elements 1. Each element 1 has a top face with a flat surface consisting of a plurality of ribs and intermediate openings 10 12 in a certain pattern and with the dimensions of ribs and openings. adapted to the current purpose of the plate, e.g. tennis. The invention is not limited to particular patterns for the upper side of the elements nor to the elements having a square shape.

Elementerne 1 begraenses pâ undersiden, som vist vendt opad i fig. 1 og 2, af nedad rettede kantribber 5 i en særlig konstruktion, ved hjælp af hvilke de hænger sammen med tilgrænsende elementer 1. Hj 0rneelementer-20 ne eller kantelementerne i en plade afviger i udform-ningen fra de mere centrale elementer i samme plade. Sâledes har det i fig. 1 længst oppe til venstre vis-te hj0rneelement kun to og de 0vrige kantelementer, der ikke ligger i noget hj0rne, kun tre kantribber 5, 25 medens de 0vrige elementer har fire sâdanne kantribber 5. Ribberne 5 og et centrait korsribbefremspring 3, samt fire diagoalribber 4 pâ bisektionen i kors-vinklerne tjener som st0tte- eller anlægsorganer mod underlaget, og deres anlægsflader har fortrinsvis af-30 fasede kanter, og ribberne fâr derved i tværsnit et noget afrundet profil.The elements 1 are restricted on the underside, as shown upwards in FIG. 1 and 2, of downwardly directed edge ribs 5 in a particular structure by which they are associated with adjacent elements 1. The corner elements or edge elements of a plate differ in design from the more central elements of the same plate. Thus, in FIG. 1 in the upper left corner corner element only two and the other edge elements not in any corner only three edge ribs 5, 25 while the other elements have four such edge ribs 5. The ribs 5 and a centrait cross rib protrusion 3, as well as four diagonal ribs 4 on the bisection of the cross-angles serve as supporting or abutment means against the support, and their abutment surfaces preferably have bevelled edges, and the ribs thereby have a somewhat rounded profile in cross section.
Pladens kant- og hj0rneelementer har til erstatning for de manglende kantribber 5 i stedet pâ de frie 35 yderkanter st0ttetappe 11 og hj0rnetappe 13 af hen-holdsvis halvcirkel- og hj0rnecirkelsektion.The edge and corner elements of the plate are to replace the missing edge ribs 5 instead of the free 35 outer edges supporting pin 11 and corner pin 13 of the semi-circle and corner circle sections, respectively.

De mod jorden anlæggende overflader er i fig. 2 vist fuldt optrukne, sâ at de lettere kan skelnes fra ele-mentoversidens netværk af ribber. Disse anlægs- og glideorganer letter bevægelsen af elementet 1 i aile 5 retninger pâ underlaget, d.v.s. letter egen- ekspansionen og egenkontraktionen af elementet og medf0rer, sammen med elementets 0vrige udformning, at f.eks. en af enkelte plader ud0vet ekspansionskraft medf0rer, at hele belægningen inden for ekspansions-10 tolerancen forskydes horisontalt. Det vil ses, at glidefladerne mod underlaget er fordelt i form af ribber i otte retninger, med undtagelse af kant-delene, med ca. 40° vinkelmellemrum, sâ at der opstèr mindst mulig friktion ved bevægelse i en vilkârlig 15 retning under indvirkning af temperaturen pâ elemen-terne 1.The ground surfaces are shown in FIG. 2 are fully drawn so that they can be more easily distinguished from the element surface network of ribs. These abutment and sliding means facilitate the movement of the element 1 in all 5 directions on the substrate, i.e. facilitates the self-expansion and the self-contraction of the element and, together with the other design of the element, means that e.g. an expansion force exerted by a few plates causes the entire coating within the expansion tolerance to be shifted horizontally. It will be seen that the sliding surfaces towards the support are distributed in the form of ribs in eight directions, with the exception of the edge parts, by approx. 40 ° angular space so as to minimize friction by movement in any direction under the influence of the temperature of the elements 1.
Kantdelene 5, der forbinder tilgrænsende elementer 1 inden for samme plade, er, som det fremgâr af fig 1 20 og 4, V- eller U-formet i snit, idet benene 14 danner selve elementkanterne, og forbindelsen mellem elemen-terne bestâr af broen 15 mellem benene. Broen 15 ud-g0r ligeledes selve anlægsoverfladen mod underlaget ved elementkanterne. Der dannes pâ denne mâde en 25 spalte 2 mellem tilgrænsende elementer 1, som muligg0r en vis udvidelse eller sammentrækning af elementerne. Til opnâelse af optimal bevægelighed af broen 15 og dræning af spalterne 2 forefindes en âb-ning 7 mellem tilgrænsende broer, kantdele 5, sâ an-30 lægsfladerne pâ denne mâde fâr en vis indbyrdes af-stand fra hinanden og muligg0r en relativ bevægelse under temperaturens indvirkning. Fig. 4 viser spalten 2 mellem to elementer, og det fremgâr, at spaltens 2 dybde ikke overstiger tykkelsen af et element.The edge portions 5 connecting adjacent elements 1 within the same plate, as shown in Figs. 1 20 and 4, are V- or U-shaped in section, the legs 14 forming the element edges themselves and the connection between the elements consisting of the bridge. 15 between the legs. The bridge 15 also forms the actual surface of the abutment against the substrate at the element edges. In this way, a gap 2 is formed between adjacent elements 1, which allows some expansion or contraction of the elements. In order to achieve optimum movement of the bridge 15 and drainage of the slots 2, an opening 7 is provided between adjacent bridges, edge portions 5, so that the contact surfaces in this way are spaced apart and allow a relative movement below the temperature of the bridge. impact. FIG. 4 shows the gap 2 between two elements, and it appears that the depth of the gap 2 does not exceed the thickness of an element.

Som det fremgàr af fig. 2 har en plade pâ to m0dende kanter fire b0sninger 8, og pâ de i forhold til disse parvis modstâende, indbyrdes m0dende kanter fire tappe 9. Tappene 9 har mindre 10 diameter end hullet i b0sningerne 8, sâ der fore-findes et vist spillerum til relativ bevægelse under temperaturens pâvirkning af disse dele.by means of coupling members consisting of a pin 9, centered on the free outer edge (s), respectively, of the element 1 of one plate cooperating with an insertion bushing 8, centered on 5 the adjacent edge of the adjacent element of the other plate. As can be seen from FIG. 2, a plate on two opposite edges has four bushings 8, and on the opposing ends, mutually opposing edges four pins 9. The pins 9 have a smaller diameter 10 than the hole in the bushings 8, so that there is some clearance for relative movement under the influence of temperature of these parts.
Alt i ait opnâr man sâledes if01ge opfindelsen, at 15 ekspansionerne af hver plade eller hvert pladeelement 1 pâ grund af varme, henholdsvis kontraktionerne af samme dele pâ grund af kulde pâ optimal mâde optages af henholdsvis pladen og elementet, og at, især i tilfælde af stærk varme,. den kraftpâvirkning, som i 20 ait fald en del af nabopladerne uvægerligt udsættes for, bibringer hele belægningen en ren horsiontal-forskydning.Thus, according to the invention, it is thus achieved that the 15 expansions of each plate or plate element 1 due to heat, respectively the contractions of the same parts due to cold, are optically absorbed by the plate and element respectively, and that, especially in the case of strong heat ,. the force exertion, which in 20 cases inevitably is exposed to a part of the neighboring plates, gives the whole coating a pure horsepower displacement.
