Description

Die Erfindung bezieht sich auf eine Sicherheitsbelagsplatte mit den Merkmalen aus dem Oberbegriff des Anspruches 1. Solche Sicherheitsbelagsplatten werden als Fertigbodenteile bevorzugt für Kleinspielfelder, als Fallschutzböden auf Kinderspielplätzen und unter Spiel- und Sportgeräten, aber auch bei sonstigen Freizeitanlagen, verwendet. Sie können auf beliebigem Untergrund aufgelegt werden, beispielsweise in ein Sandbett, aber auch auf eine Rohbetondecke o. dgl. unter Zwischenschaltung von Dämmaterial.The invention relates to a safety covering plate with the features from the preamble of claim 1. Such safety covering plates are preferably used as prefabricated floor parts for small playing fields, as fall protection floors on children's playgrounds and under play and sports equipment, but also in other leisure facilities. They can be placed on any surface, for example in a sand bed, but also on a raw concrete ceiling or the like with the interposition of insulation material.

Eine Scherheitsbelagsplatte ähnlicher Art ist aus dem DE-U-7 724 504 bekannt, bei der bereits das Mittelfeld der Deckplatte des Belagskörpers frei von irgendwelchen Verankerungen zu dem starren Trägerkörper gehalten ist und ein umlaufender Rand zur Verankerung der Deckplatte an dem Trägerkörper ausgenutzt wird. Dieser umlaufende Rand kann außerhalb oder innerhalb des Umrisses des Trägerkörpers an der Deckplatte angeordnet sein und über die Höhe der noppenartigen Abstandshalter hinaus nach unten reichen, wo er in einer nach innen gekehrten Umbiegung endet. Diese Umbiegung des Randes ist in das Material des Trägerkörpers eingebettet und von diesem allseits umschlossen. Die Herstellung dieser Scherheitsbelagspatten erfolgt in der Weise, daß der Belagskörper umgekehrt in eine Form eingelegt wird, wobei die noppenförmigen Abstandshalter nach oben zeigen. Sodann wird eine Trennplatte auf die Spitzen der noppenförmigen Abstandshalter aufgelegt und Beton oder eine sonstige aushärtbare Masse eingefüllt. Dabei wird die nach innen gerichtete Umbiegung des umlaufenden Randes in das aushärtbare Material eingeformt. Nach dem Aushärten der Masse des Trägerkörpers werden Belagskörper und Trägerkörper, nunmehr aneinanderhängend, aus der Form entnommen. Diese Art der Herstellung ist besonders arbeits- und kostenintensiv. Die Entformung der Sicherheitsbelagspatte ist dadurch erschwert, daß die Deckplatte am umlaufenden Rand in Höhe der Deckplatte einen nach außen vorstehenden Aufsatz aufweist, der sich auch für das Verlegen der Sicherheitsbelagsplatten insofern nachteilig auswirkt, als sich benachbarte Belagskörper nur im Bereich der Deckplatten über ihre Fortsätze aneinander abstützen können, wenn eine entsprechend gedrängte, fugenlose Verlegung erfolgt. Es besteht die Gefahr, daß die Deckplatten im verlegten Zustand Druckkräfte aufnehmen müssen und dadurch ihre Oberseite leicht eine Wellen- bzw. Beulenform einnimmt, die nicht nur unschön ist, sondern auch beim Gebrauch stört. Durch die aneinanderliegenden Fortsätze wird der Randbereich, der im übrigen ja umlaufend gleichsam in das Material des Trägerkörpers eingebettet ist, noch zusätzlich versteift, so daß in diesem Randbereich ungleiche Federungseigenschaften der Deckplatte zu dem Mittelbereich mit den noppenförmigen Abstandshaltern entstehen. Während der Mittelbereich durch die noppenförmigen Abstandshalter, die lose auf der Oberseite des Trägerkörpers aufliegen, punktförmig abgestützt ist, ist der umlaufende Rand linienförmig abgestützt, umlaufend festgehalten und damit vergleichsweise versteift.A security covering plate of a similar type is known from DE-U-7 724 504, in which the middle field of the cover plate of the covering body is already kept free of any anchoring to the rigid support body and a circumferential edge is used for anchoring the cover plate to the support body. This peripheral edge can be arranged outside or inside the outline of the carrier body on the cover plate and can extend downward beyond the height of the knob-like spacers, where it ends in an inward bend. This bending of the edge is embedded in the material of the carrier body and is enclosed on all sides by it. These security sheeting panels are produced in such a way that the covering body is inserted into a mold in reverse, with the knob-shaped spacers pointing upwards. A separating plate is then placed on the tips of the knob-shaped spacers and concrete or another hardenable mass is poured in. The inward bend of the peripheral edge is molded into the hardenable material. After the mass of the carrier body has hardened, the covering body and carrier body, now attached to one another, are removed from the mold. This type of production is particularly labor and cost intensive. De-molding of the safety covering plate is made more difficult by the fact that the cover plate has an outwardly projecting attachment on the peripheral edge at the height of the cover plate, which also has a disadvantageous effect for the laying of the safety covering plates in that adjacent covering bodies only adjoin one another in the area of the cover plates via their extensions can support if there is a correspondingly compact, seamless installation. There is a risk that the cover plates in the installed state have to absorb compressive forces and thereby their upper side easily takes on a wave or bulge shape, which is not only unattractive but also disturbs in use. Due to the adjoining extensions, the edge area, which is embedded in the material of the carrier body all the way around, is additionally stiffened, so that in this edge area unequal resilience properties of the cover plate to the central area with the knob-shaped spacers arise. While the central area is supported in a punctiform manner by the knob-shaped spacers, which rest loosely on the upper side of the carrier body, the peripheral edge is supported in a linear manner, held all the way round and thus comparatively stiffened.

Auch die niederländische Veröffenlichung Nr. 7014 057 zeigt eine Sicherheitsbelagsplatte der beschriebenen Art, bei der der Trägerkörper in seinem unteren Bereich eine nach innen gerichtete umlaufende Abstufung aufweist, die in der Unterseite des Trägerkörpers endet. Die zugehörige Deckplatte weist einen außerhalb des Umrisses des Trägerkörpers nach unten reichenden Rand auf, der in einer nach innen gekehrten Umbiegung endet. Die Höhe der Umbiegung entspricht der Höhe der durch die Abstufung gebildeten Stufe. Deckplatte und Trägerkörper werden bei der Herstellung der Sicherheitsbelagsplatte miteindander verbunden. Bei dieser Verankerung greift die Umbiegung des Randes nicht nur in die umlaufende Abstufung ein, sondern Deckplatte und Trägerkörper sind darüberhinaus durch Klemmen, Kleben oder durch Anwendung mechanischer Mittel fest miteindander verbunden. Beim Verlegen der Sicherheitsbelagsplatte wird die Umbiegung des Randes der Deckplatte zwischen dem Untergrund und dem Trägerkörper eingeklemmt, so daß keinerlei Federungsmöglichkeit der Umbiegung oder des Randes gegeben ist, zumal diese bekannten Sicherheitsbelagsplatten mit vertikalen Außenseiten des umalufenden Rands unmittelbalr aneinderstoßend verlegt werden. Hierauf is es zurückzuführen, daß diese Belagsplatte im Bereich der Ränder sehr viel härter ausgebildet ist als im übrigen Plattenbereich, so daß die Elastizität der Platten im verlegten Verband über die verlegte Fläche nicht gleichmäßig ist.Dutch publication no. 7014 057 also shows a safety covering plate of the type described, in which the carrier body has an inward circumferential gradation in its lower region, which ends in the underside of the carrier body. The associated cover plate has an edge which extends downward outside the outline of the carrier body and which ends in an inward bend. The amount of the bend corresponds to the level of the step formed by the gradation. The cover plate and carrier body are connected to one another during the production of the safety covering plate. With this anchoring, the bending of the edge not only engages in the circumferential gradation, but the cover plate and carrier body are moreover firmly connected to one another by clamping, gluing or by using mechanical means. When laying the safety covering plate, the bend in the edge of the cover plate is clamped between the substrate and the support body, so that there is no possibility of suspension of the bend or the edge, especially since these known safety covering plates with vertical outer sides of the air-circulating edge are laid immediately in an opposing manner. It can be attributed to the fact that this covering plate is made much harder in the area of the edges than in the rest of the plate area, so that the elasticity of the plates in the installed bond is not uniform over the installed area.

Der Erfindung liegt die Aufgabe zugrunde, eine Sicherheitsbelagsplatte dieser Art so weiterzubilden, daß ein gleichmäßiger Kraftabbau über die gesamte Platte und über deren Grenzen hinweg im verlegten Verband erreicht wird. Die Sicherheitsbelagsplatte soll also in all ihren Bereichen gleiche oder zumindest etwa gleiche Nachgiebigkeit aufweisen.The invention is based on the object of developing a safety covering plate of this type in such a way that a uniform reduction in force is achieved across the entire plate and beyond its boundaries in the installed bond. The safety covering plate should therefore have the same or at least approximately the same flexibility in all its areas.

Dies wird erfindungsgemäß durch die im Kennzeichen des Anspruches 1 angegebenen Merkmale erreicht. Der Belagskörper läßt sich mit dem umlaufenden Rand der Deckplatte mit seiner nach innen gerichtete Umbiegung gleichsam auf den Trägerkörper aufknüpfen, und zwar auswechselbar. Durch diese Verbindung zwischen Deckplatte und Trägerkörper werden die Federungseigenschaften ansonsten kaum beinflußt, so daß eine funktionale Trennung zwischen der Verankerung der Deckplatte an dem Trägerkörper einerseits und den die federnde Nachgiebigkeit der Deckplatte an dem Trägerkörper andererseits bewirkenden Merkmalen gegeben ist. Da sich der umlaufende Rand nicht mehr auf- bzw. an dem Trägerkörper abstützt, sondern gleichsam nach der anderen Richtung nur in eine Hinterschneidung eingreift, wird das Ausfedern des Randes in den Freiraum durchaus zugelassen. Damit wird die federnde Nachgiebigkeit bei Belastung im wesentlichen von der Ausbildung und Anordnung der Abstandhalter bestimmt. Diese lassen sich nun tatsächlich auch gleichmäßig über die Innenseite der Deckplatte verteilt anordnen, ohne daß der Verband durch zusätzliche Verankerungskörper mit dann wieder notwendigerweise unterschiedlichen Eigenschaften gestört würde. Gleichzeitig mit der Lösung der genannten Aufgabe treten auch einige überraschende Vorteile auf. Belagskörper und Trägerkörper können getrennt voneinander hergestellt, zur Baustelle transportiert, dort miteinander verbunden und verlegt werden. Die Auswechselbarkeit bei Abnutzung der Deckplatte oder bei Bruch des Trägerkörpers ist gegeben. Das Luftpolster zwischen den noppenförmigen Abstandshaltern ist nicht mehr hermetisch abgeschlossen, weil der umlaufende Rand nicht in die Masse des Trägerkörpers eingebettet ist. Ein Luftaustausch von dem Luftpolster zur Atmosphäre ist damit möglich. Dies bedeutet, daß auch bei längerer Sonnenscheineinstrahlung bzw. Temperatureinwirkung diesbezüglich eine Wellen- und Beulenbildung an der Oberfläche der Belagsplatten vermieden wird. Durch den losen überstehenden Rand des Belagskörpers aus Gummi lassen sich Maßtoleranzen der Trägerkörper aus Beton leichter ausgleichen.This is achieved according to the invention by the features specified in the characterizing part of claim 1. The covering body can be, as it were, exchangeable with the peripheral edge of the cover plate with its inward bend on the carrier body. Through this connection between the cover plate and the support body, the suspension properties are otherwise hardly influenced, so that there is a functional separation between the anchoring of the cover plate on the support body on the one hand and the characteristics causing the resilient flexibility of the cover plate on the support body on the other hand. Because the revolving No longer supports the edge or supports it on the carrier body, but rather only engages in an undercut in the other direction, the extension of the edge into the free space is entirely permitted. The resilient flexibility under load is essentially determined by the design and arrangement of the spacers. These can now actually be evenly distributed over the inside of the cover plate, without the bondage being disturbed by additional anchoring bodies which then necessarily have different properties. At the same time as the solution to the stated problem, there are also some surprising advantages. Covering body and carrier body can be manufactured separately from one another, transported to the construction site, connected there and laid. It can be replaced if the cover plate wears or if the carrier body breaks. The air cushion between the knob-shaped spacers is no longer hermetically sealed, because the peripheral edge is not embedded in the mass of the carrier body. An air exchange from the air cushion to the atmosphere is possible. This means that even in the event of prolonged sunshine or exposure to temperature, the formation of waves and bumps on the surface of the covering plates is avoided. The loose, protruding edge of the rubber covering body makes it easier to compensate for dimensional tolerances of the concrete support body.

Schließlich ist die Verlegung der Sicherheitsbelagsplatten auch vergleichsweise einfacher, da sich die nachgiebigen Ränder zweier benachbarter Platten unter Druck im Bereich der Trägerkörper aneinander anpassen, ohne daß hier vorstehende Fortsätze im Wege wären. Auch ist es möglich, Belagskörper mit unterschiedlichen Eigenschaften herzustellen und dann wahlweise mit denselben Trägerkörpern zu verbinden. Dies geschieht durch Änderung der Höhe und der Form der noppenartigen Abstandshalter. In allen Ausführungsformen wird durch die Freiräume ein Kanalsystem für die unterflächige Wasserabführung geschaffen.Finally, the laying of the safety covering panels is also comparatively easier, since the resilient edges of two adjacent panels adapt to one another under pressure in the region of the carrier bodies, without the protruding projections being in the way here. It is also possible to produce covering bodies with different properties and then optionally to connect them to the same carrier bodies. This is done by changing the height and shape of the knob-like spacers. In all embodiments, a channel system for the surface drainage is created by the free spaces.

Die Verwirklichung der im Anspruch 2 angegebenen Merkmale führt zu einer vereinfachten Verlegung und zu einem fächigen Anliegen benachbarter Platten im Verband. In horizontaler Richtung werden dabei im Bereich der Deckplatte keine nennenswerten Kräfte übertragen. Die Abstützung in horizontaler Richtung erfolgt auf der Höhe der Trägerplatten.The realization of the features specified in claim 2 leads to a simplified laying and to a flat concern of adjacent panels in the association. No significant forces are transmitted in the horizontal direction in the area of the cover plate. The support in the horizontal direction is at the height of the carrier plates.

Die klare funktionale Trennung der Abstützung der Deckplatte über die noppenartigen Abstandshalter an der Oberfläche des Trägerkörper einerseits und der verknüpfenden Verbindung zwischen Belagskörper und Trägerkörper andererseits ergibt die völlige Freiheit in der Anordnung und Verteilung und Ausbildung der noppenförmigen Abstandshalter so daß es möglich wird, die im Anspruch 3 niedergelegten Merkmale zu benutzen, um ggfs. die Nachgiebigket der Sicherheitsbelagsplatte im Randbereich zu verringern und damit an die Nachgiebigket im Mittelbereich der Belagskörper anzupassen.The clear functional separation of the support of the cover plate on the knob-like spacers on the surface of the carrier body on the one hand and the connecting connection between the covering body and carrier body on the other hand gives complete freedom in the arrangement and distribution and design of the knob-shaped spacers so that it is possible in the claim 3 used features to reduce the elasticity of the safety covering plate in the edge area and to adapt it to the elasticity in the central area of the covering body.

Auch durch die Verwirklichung der im Anspruch 4 angegebenen Merkmale ist es möglich, die Federungseigenschaften bzw. den Kraftabbau zu beeinflussen.Also by realizing the features specified in claim 4, it is possible to influence the suspension properties or the force reduction.

Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschreiben. Es zeigen:

  • Figur 1 einen Vertikalschnitt durch Teile von zwei benachbarten, in Verband verlegten Sicherheitsbelagsplatten,
  • Figur 2 eine Draufsicht auf den Belagskörper der Sicherheitsbelagsplatte von unten, im Ausschnitt und
  • Figur 3 einen Vertikalschnitt durch einen als Gummifeder ausgebildetet Abstandshalter.
Embodiments of the invention are shown in the drawings and are described in more detail below. Show it:
  • FIG. 1 shows a vertical section through parts of two adjacent safety covering plates laid in a bond,
  • Figure 2 is a plan view of the covering body of the safety covering plate from below, in the cutout and
  • 3 shows a vertical section through a spacer designed as a rubber spring.

Jede Sicherheitsbelagsplatte 1 besteht im wesentlichen aus zwei Teilen, nämlich einem Trägerkörper 2 und je einem Belagskörper 3. Die Trägerkörper 2 können aus Beton, Holz, Kunststoff od. dgl. bestehen, während die Belagskörper 3 in der Regel aus Gummi hergestellt sind. Jeder Belagskörper 3 besitzt eine Deckplatte 4 die auf ihrer Oberseite 5 die begehbare Oberfläche abgibt, während auf ihrer Unterseite 6 noppenförmige Abstandshalter 7 in großer Vielzahl und regelmäßiger Anordnung vorgesehen sind, die zweckmäßig aus Entförmungsgründen konisch zulaufen und auf der Oberfläche 8 des Trägerkörpers 2 lose aufliegen. Auf diese Art und Weise wird die Deckplatte 4 im Abstand von der Oberfläche 8 des Trägerkörpers 2 gehalten, wobei zwischen den Abstandshaltern 7 Freiräume 9 gebildet sind, die die Federungseigenschaften wesentlich verbessern. Es versteht sich, daß die Abstandshalter 7 in ihrer Höhe, Ausbildung und Anordnung auf den gewünschten Kraftabbau der Sicherheitsbelagsplatte abgestimmt bzw. abgestellt sind. Die Abstandshalter 7 erstrecken sich in regelmäßiger Anordnung über die gesamte Unterseite der Deckplatte 4, die im übrigen ebenso groß ausgebildet ist, wie die Oberfläche 8 des Trägerkörpers 2.Each safety covering plate 1 consists essentially of two parts, namely a carrier body 2 and a covering body 3 each. The carrier bodies 2 can consist of concrete, wood, plastic or the like, while the covering bodies 3 are generally made of rubber. Each covering body 3 has a cover plate 4 which gives off the accessible surface on its upper side 5, while on its underside 6 knob-shaped spacers 7 are provided in a large number and in a regular arrangement, which are expediently tapered for reasons of demolding and lie loosely on the surface 8 of the carrier body 2 . In this way, the cover plate 4 is held at a distance from the surface 8 of the carrier body 2, with free spaces 9 being formed between the spacers 7, which substantially improve the suspension properties. It is understood that the spacers 7 are adjusted in their height, design and arrangement to the desired force reduction of the safety covering plate. The spacers 7 extend in a regular arrangement over the entire underside of the cover plate 4, which is otherwise as large as the surface 8 of the carrier body 2.

An die Deckplatte 4, also mit Abstand zum Trägerkörper 2, schließt sich ein umlaufender im wesentlichen vertikal sich erstreckender Rand 10 an, der außerhalb der Umrißlinie des Trägerkörpers 2 vorgesehen ist. Dieser Rand 10 reicht nicht nur bis zur Oberfläche 8 des Trägerkörpers 2, die er selbst vermeidet, sondern noch weiter nach unten bis zu einem Teil der Materialhöhe des Belagskörpers 3. An seinem unteren Ende ist eine Umbiegung 11 vorgesehen, unter der wiederum ein Freiraum 12 gebildet bzw. angeordnet ist. Die Ausbildung im einzelnen ist auf die Ausbildung des Trägerkörpers 2 abgestimmt. Dieser besitzt in seiner einfachsten Ausführungsform einen oberen Teil 13 mit vergleichsweise größerem Umriß und einen unteren Teil 14, der mindestens um die Breite der Umbiegung 11 zurückstehend angeordnet ist. Selbstverständlich ist bei Ausbildung in Beton der Trägerkörper 2 einstückig und durchgehend gefertigt. Bei Verwendung von zwei mit einander verbundenen, beispielsweise verklebten oder verschraubten Holzplatten zur Bildung des Trägerkörpers 2 können selbstverständlich mehrstückige Teile aneinandergefügt werden. Eine solche Ausbildung aus Holzplatten bietet sich insbesondere für Turnhallen an, in denen an wechselnden Orten Turngeräte aufgestellt werden und auch wieder abgebaut werden müssen.The cover plate 4, that is to say at a distance from the carrier body 2, is adjoined by a circumferential edge 10 which extends substantially vertically and is provided outside the outline of the carrier body 2. This edge 10 not only extends to the surface 8 of the carrier body 2, which it avoids itself, but further down to a part of the material height of the covering body 3. At its lower end, a bend 11 is provided, under which in turn a space 12 is formed or arranged. The training in detail is coordinated with the training of the carrier body 2. In its simplest embodiment, this has an upper part 13 comparatively larger outline and a lower part 14 which is arranged at least by the width of the bend 11. Of course, in the case of training in concrete, the carrier body 2 is made in one piece and continuously. When using two interconnected, for example glued or screwed wooden panels to form the support body 2, multi-piece parts can of course be joined together. Such training from wooden panels is particularly suitable for gyms in which gymnastics equipment is set up at different locations and also has to be dismantled again.

Anhand von Fig. 2 ist deutlich erkennbar, wie einige der Abstandshalter 7' etwas aus dem Verband der übrigen Abstandshalter 7 herausgelöst und mit dem umlaufenden Rand 10 direkt verbunden sind, so daß dieser relativ hohe Rand, der sich im wesentlichen vertikal erstreckt, hier eindeutig abgestützt ist und ein Einknicken dieses Randes 10 an dieser Stelle vermieden wird.With reference to FIG. 2 it can be clearly seen how some of the spacers 7 'are somewhat detached from the assembly of the other spacers 7 and are directly connected to the peripheral edge 10, so that this relatively high edge, which extends essentially vertically, is clearly here is supported and a buckling of this edge 10 is avoided at this point.

Zur Erzielung von Belagsplatten unterschiedlicher Typen, also mit unterschiedlichem Kraftabbau können die Abstandshalter 7, 7, in unterschiedlicher Bauhöhe ausgebildet werden, wobei es wichtig ist, niemals auf die Freiräume 9 zu verzichten. Man kann aber die Bauhöhe dann besonders klein wählen, wenn die Abstandshalter 7 hohl ausgebildet werden, wie dies aus dem Ausschnitt gemäß Fig. 3 ersichtlich ist. Die Kegelform der Abstandshalter 7 muß doch relativ geringfügig gewählt werden, so daß eine leichte Entformung des Gummiteils aus dem Werkzeug möglich ist.In order to achieve covering plates of different types, that is to say with different force reduction, the spacers 7, 7 can be designed in different overall heights, it being important never to do without the free spaces 9. However, the overall height can be chosen to be particularly small if the spacers 7 are made hollow, as can be seen from the detail according to FIG. 3. The conical shape of the spacers 7 has to be chosen relatively slightly, so that the rubber part can be easily removed from the mold.

Durch die geometrische Gestaltung der Höhlung 15 können die Werte der auf diese Weise gebildeten Gummihohlfeder konstruktiv bestimmt bzw. festgelegt werden. Die Vielzahl dieser Hohlfedern auf der Unterseite 6 der Deckplatte 4 ergibt dann insgesamt gleichmäßige Eigenschaften, unabhängig vom Ort an der einzelnen Sicherheitsbelagsplatte.Due to the geometric design of the cavity 15, the values of the hollow rubber spring formed in this way can be determined constructively. The large number of these hollow springs on the underside 6 of the cover plate 4 then gives overall uniform properties, irrespective of the location on the individual safety covering plate.

Claims (4)

1. Elastically resilient safety covering sheet, especially for floors, consisting of a rigid supporting body (2) and a covering body (3) which is provided at the top side (8) of the latter and consists of elastically resilient material and which has a cover panel (4) which is held at a distance from the supporting body (2) and which only possesses on its underside (6) a plurality of knoblike spacers (7) which, distributed essentially uniformly, rest loosely on the surface (8) of the supporting body (2), me cover panel (4) having a continuous edge (10) located outside the outline of the supporting body (2) and with an inward-directed bent portion (11) by means of which it engages a continous inward step (13, 14) positioned in the lower region of the supporting body (2), characterised in that the continuous edge (10) of the cover panel (4) by means of its bent portion (11) in interchangeably slipped in that way on the step (13,14) of the supporting body (2) and in that such a free space (12) is provided under the bent portion (11) of the continuous edge (10) of the cover panel (4), that the continuous edge (10) admits to spring off into the free space (12) and the resilient flexibility of the cover panel (4) is substantially fixed by the performance and the arrangement of that spacers (7).
2. Safety covering sheet according to Claim 1, characterised in that the continuous edge (10) extends vertically on its outside.
3. Safety covering sheet according to Claims 1 and 2, characterised In that the continuous edge (10) is connected on its inside to some spacers (7') arranged adjacent to the edge.
4. Safety covering sheet according to Claims 1 to 3, characterised in that on the underside of the cover panel (4), next to the spacers (7'), the further spacers (7) are made slightly frustoconical and, starting from their bearing surface on the supporting body (2), hollow at least over a region of their height.
