Description

Die Erfindung betrifft eine Laufsohle mit Nocken für Sportschuhe, insbesondere Fussballschuhe, mit von der Laufseite der Laufsohle vorspringenden Befestigungsansätzen, an denen die napfförmig ausgebildeten Nocken auswechselbar befestigt sind.The invention relates to an outsole with cams for sports shoes, in particular soccer shoes, with fastening projections projecting from the running side of the outsole, to which the cup-shaped cams are exchangeably fastened.

Nach dem Sprachgebrauch werden unter Nockensohlen solche Sportschuhsohlen verstanden, auf denen - überwiegend einstückig mit der Sohle ausgebildete - Greifelemente in einer Anzahl von bis zu 20 ausgebildet sind, wobei diese Greifelemente aufgrund ihres Werkstoffes eine gewisse Federelastizität und Nachgiebigkeit haben. Solche Nockensohlen werden bevorzugt von Sportlern dann verwendet, wenn die elastische Verformbarkeit der Nocken - im Gegensatz ·zu den regelmässig harten auswechselbaren Stollen - und die daraus resultierende Dämpfung ausgenützt werden sollen. Dies gilt vor allem auf harten Plätzen und Böden, auf denen trotzdem auf eine Greifelementwirkung nicht verzichtet werden kann. Nockensohlen werden weitgehend auch im Training von Fussballspielern verwendet, da sie als schonend empfunden werden.According to common usage, cam soles are understood to mean those athletic shoe soles on which gripping elements - predominantly made in one piece with the sole - are formed in a number of up to 20, these gripping elements having a certain elasticity and flexibility due to their material. Such cam soles are preferably used by athletes when the elastic deformability of the cams - in contrast to the regularly hard interchangeable studs - and the resulting damping are to be used. This is especially true on hard places and floors, on which nevertheless on a gripping element effect cannot be dispensed with. Cam soles are also widely used in the training of football players, as they are perceived as being gentle.

Ein seit jeher vorhandenes Problem der Nockensohlen besteht darin, dass nach dem Verschleiss der Nocken die ganze Sohle und damit der Sportschuh unbrauchbar sind, auch wenn im übrigen der Schaft noch in Ordnung ist. Um daher die Lebensdauer der Nockensohle mit der des ganzen Sportschuhes in Einklang zu bringen, ist es notwendig, die Nockensohle aus einem gegen Verschleiss sehr widerstandsfähigen Kunststoffmaterial herzustellen. Da hierdurch die Sohle verhältnismässig teuer wird, ist auch schon vorgeschlagen worden, die Nocken allein aus einem verschleissfesten Material zu fertigen und sie mit der aus billigerem Werkstoff bestehenden Sohle im Giessvorgang zu verbinden. Das hat aber den Nachteil, dass der härtere Werkstoff der Nocken diesen in einem beträchtlichen Ausmass die gerade von Nocken gevronschte.Elastizität und Dämpfungseigenschaft nimmt. Dies gilt grundsätzlich auch für solche Nockensohlen der eingangs beschriebenen Art, bei denen aus verschleissfestem Werkstoff bestehende "Nockenkappen" an Befestigungsansätzen der Laufsohle, die ein Aussengewinde tragen, durch Schrauben befestigbar sind (FR-PS 20 70 253). Als Nachteil kommt bei diesen bekannten Nockensohlen noch dazu, dass die Befestigungsansätze häufig irreparabel beschädigt werden, wenn der Sportler es versäumt, rechtzeitig vor dem vollständigen Verschleiss der Laufseite der Nockenkappen diese auszuwechseln.A problem that has always existed for the cam soles is that after the cams wear out, the entire sole and thus the sports shoe are unusable, even if the shaft is still in order. Therefore, in order to harmonize the life of the cam sole with that of the entire sports shoe, it is necessary to manufacture the cam sole from a plastic material that is very resistant to wear. Since this makes the sole relatively expensive, it has also been proposed to manufacture the cams solely from a wear-resistant material and to connect them to the sole made of cheaper material in the casting process. However, this has the disadvantage that the harder material of the cams takes away to a considerable extent the elasticity and damping properties that have just been dominated by cams. This also applies in principle to those cam soles of the type described at the outset, in which "cam caps" made of wear-resistant material can be fastened to fastening attachments of the outsole, which carry an external thread, by screws (FR-PS 20 70 253). A disadvantage of these known cam soles is that the fastening approaches are often irreparably damaged if the athlete fails to replace the cam caps in good time before the running side is completely worn out.

Aufgabe der Erfindung ist es deshalb, eine Nockensohle der eingangs beschriebenen Art zu schaffen, deren Sohlenkörper insgesamt aus einem verhältnismässig billigen Material hergestellt ist und die austauschbare Nocken aus einem hochverschleissfesten Werkstoff trägt, ohne dass die Dämpfungseigenschaften der Nocken verloren sind und ein vorübergehend nicht beachteter zu weitgehender Verschleiss der Nocken die Befestigungsansätze der Laufsohle unbrauchbar macht.The object of the invention is therefore to provide a cam sole of the type described above, the sole body of which is made of a relatively cheap material and which carries interchangeable cams made of a highly wear-resistant material, without the damping properties of the cams being lost and a temporarily ignored one Extensive wear of the cams renders the attachments of the outsole unusable.

Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass jeder Befestigungsansatz eine zur Laufseite der Laufsohle hin weisende Schulter besitzt, dass auf den Befestigungsansatz eine Hülse aufschiebbar ist, die mindestens ein durch eine zugeordnete öffnung der Hülsenwandung hindurch bewegbares und die Schulter des zugeordneten Befestigungsansatzes dabei hintergreifendes Hakenelement besitzt, und dass auf die Hülse eine Nocke aufsteckbar ist, wobei das die Schulter hintergreifende Hakenelement geringfügig über die öffnung nach aussen vorsteht und mit der Innenfläche der Nocke in einem diese festhaltenden Reibschluss steht.According to the invention, this object is achieved in that each fastening attachment has a shoulder pointing towards the running side of the outsole, that a sleeve can be slid onto the attachment attachment, which sleeve has at least one hook element which can be moved through an associated opening in the sleeve wall and engages behind the shoulder of the associated attachment attachment , and that a cam can be plugged onto the sleeve, the hook element which engages behind the shoulder protrudes slightly beyond the opening and is in frictional engagement with the inner surface of the cam.

Die erfindungsgemässe Nockensohle besitzt somit Befestigungsansätze, die nicht als Schraubansätze mit einem Aussengewinde ausgebildet sind, sondern lediglich in einem bestimmten Abstand von ihrem freien Ende, zwischen diesem und der Laufseite der Laufsohle, eine zur Laufseite hin weisende Schulter besitzen. Die lediglich eine kappen- oder fingerhutförmige "Nockenschale" bildenden Nocken aus einem hochfesten Kunststoffmaterial werden an diesen Befestigungsansätzen mittels einer Hülse befestigt, die sich an ihrer Innenfläche mittels des Hakenelementes, d.h. also durch Formschluss, an der Schulter festhält, an ihrer Aussenfläche aber durch das geringfügig überstehende Hakenelement die Nockenschale durch Pressitz bzw. einen entsprechenden Reibschluss hält. Die Nockenschale selbst sorgt dafür, dass das Hakenelement sich nicht aus dem formschlüssigen Eingriff mit der Schulter durch die öffnung der Hülsenwandung hindurch herausbewegen kann, so dass ohne eine Entfernung der Nocke von der Hülse letztere nicht von dem Befestigungsansatz abgezogen werden kann. An der Aussenfläche der Nocke oder Nockenschale können Grifflächen vorgesehen werden, die mittels eines Werkzeuges ein Abziehen unter überwindung des herrschenden Reibschlusses mit der Hülse ermöglichen. Dies ist dann erforderlich, wenn die Auftrittsflä.che der Nockenschale so weit verschlissen ist, dass die Gefahr einer Beschädigung des zugeordneten Befestigungsansatzes besteht. Gleichwohl ist eine solche Beschädigung des freien Stirnendes des Befestigungsansatzes nicht kritisch, weil die die Haltewirkung ausübende Schulter erst in einem bestimmten Abstand von dem freien Stirnende angeordnet ist, so dass auch durch einen gewissen Verschleiss des Befestigungsansatzes dessen Funktion nicht beeinträchtigt wird. Ein Verschleiss der Hülse selbst ist nicht problematisch, da diese ebenso wie die Nockenschale selbst leicht ausgewechselt werden kann.The cam sole according to the invention thus has fastening attachments which are not designed as screw attachments with an external thread, but only at a certain distance from their free end, between the latter and the running side of the outsole, have a shoulder pointing towards the running side. The cams from a single cap or thimble-shaped "cam shell" High-strength plastic material is attached to these attachment lugs by means of a sleeve that adheres to the inside of the shoulder by means of the hook element, that is to say by positive locking, on the shoulder, but on the outside surface by the slightly protruding hook element holds the cam shell by press fit or a corresponding frictional connection. The cam shell itself ensures that the hook element cannot move out of the form-fitting engagement with the shoulder through the opening of the sleeve wall, so that the cam cannot be removed from the fastening attachment without removing the cam from the sleeve. Grip surfaces can be provided on the outer surface of the cam or cam shell, which allow a tool to be pulled off while overcoming the prevailing frictional engagement with the sleeve. This is necessary if the tread surface of the cam shell is worn out to such an extent that there is a risk of damage to the associated attachment projection. Nevertheless, such damage to the free end face of the fastening attachment is not critical, because the shoulder which exerts the holding action is arranged only at a certain distance from the free end face, so that its function is not impaired by a certain amount of wear on the attachment attachment. Wear of the sleeve itself is not a problem, since it, like the cam shell itself, can be easily replaced.

Bei der erfindungsgemässen Laufsohle besteht zweckmässigerweise der Sohlenkörper einschliesslich der damit einstückigen Befestigungsansätze aus einem verhältnismässig weichen und infolgedessen nicht besonders verschleissfesten Kunststoffmaterial, z.B. aus PVC. Die Nocken oder Nockenschalen, zweckmässigerweise auch die Hülsen, bestehen dagegen aus einem sehr verschleissfesten Kunststoffmaterial, z.B. aus einem Polyurethan. Da die Nocken nur einen äusseren "Überzug" für die Befestigungsansätze der Laufsohle bilden, behält die Gesamtanordnung Nocke/Befestigungsansatz die für Nocken typische und gewünschte dämpfende Nachgiebigkeit.In the outsole according to the invention there is a purpose moderately the sole body including the one-piece fastening lugs made of a relatively soft and consequently not particularly wear-resistant plastic material, for example made of PVC. The cams or cam shells, expediently also the sleeves, consist of a very wear-resistant plastic material, for example of a polyurethane. Since the cams only form an outer "covering" for the attachment lugs of the outsole, the overall arrangement of the cam / attachment lug retains the damping flexibility typical of cams and desired.

Nach einer vorteilhaften Ausführungsform ist vorgesehen, dass die Befestigungsansätze jeweils vom Boden einer flachen Vertiefung in die Laufseite der Laufsohle vorspringen, in die die Nocke oder Nockenschale im aufgesteckten Zustand mit ihrem Rand eingepasst ist. Da hierdurch parallel zur Laufsohle wirkende Kräfte, die die Nocken belasten, nicht nur allein von den Befestigungsansätzen, sondern auch von den Rändern der Vertiefungen übertragen werden, ist es hierdurch möglich, den Reibschluss zwischen den Nockenschalen und den Hülsen weniger streng zu wählen, was dem leichteren Abziehen, falls dies gewünscht ist, zugute kommt.According to an advantageous embodiment, it is provided that the attachment projections each protrude from the bottom of a shallow depression into the running side of the outsole, into which the edge of the cam or cam shell is fitted in the attached state. Since this causes forces acting parallel to the outsole, which load the cams, not only to be transmitted by the fastening lugs alone, but also by the edges of the depressions, it is possible in this way to choose the frictional connection between the cam shells and the sleeves less strictly, which is what easier pulling off, if desired, benefits.

Die Befestigungsanätze für die Nocken können anstelle einer einstückigen Ausführung auch in der Form mit dem Hauptkörper der Laufsohle verbunden sein, dass sie in diesen mittels einer Befestigungsplatte eingebettet und verankert sind. Dies gibt die Möglichkeit, für die Befestigungsansätze ein auch von der Sohle abweichendes Material zu wählen, das besonders nachgiebig elastisch ist, um hierdurch eine Einbusse an Beweglichkeit und Nachgiebigkeit der Nocken durch deren härteren Werkstoff wieder auszugleichen.Instead of a one-piece design, the attachment lugs for the cams can also be connected to the main body of the outsole in such a way that they are embedded and anchored therein by means of a fastening plate. This gives the option of one for the mounting lugs as well choose a material that differs from the sole and is particularly resiliently elastic in order to compensate for a loss in mobility and resilience of the cams due to their harder material.

Die nicht im Ganzen dargestellte Laufsohle 1, die beispielsweise aus PVC besteht, besitzt eine Vielzahl, z.B. zwanzig, von Befestigungsansätzen 2, die mit dem Laufsohlenkörper einstückig ausgebildet sind. Die Befestigungsansätze 2 springen von dem Boden 3 einer flachen kreisförmigen Vertiefung 4 vor und haben eine Länge von beispielsweise 10 mm. Jeder Befestigungsansatz 2 weist etwa in der Mitte seiner Länge eine zu dem Boden 3 hin gerichtete Schulter 5 auf, die im gezeigten Ausführungsbeispielentsprechend dem Kreisquerschnitt des Befestigungsansatzes 2 kreisringförmig ist. Der Abstand der Schulter 5 von dem Boden 3 ist mit a bezeichnet.The outsole 1, which is not shown in its entirety, which consists, for example, of PVC, has a multiplicity, for example twenty, of attachment lugs 2 which are formed in one piece with the outsole body. The attachment lugs 2 project from the bottom 3 of a flat circular depression 4 and have a length of, for example, 10 mm. Each attachment lug 2 has a shoulder 5 directed towards the bottom 3 approximately in the middle of its length A shown usführungsbeispielen tsprechend the circular cross section of the fixing lug 2 is annular. The distance of the shoulder 5 from the floor 3 is denoted by a.

Auf den Befestigungsansatz 2 ist eine im Ganzen mit 6 bezeichnete Hülse aufschiebbar (Figuren 2a, 2b), die ebenfalls aus PVC bestehen kann. Einstückig mit der Hülse 6 sind einander diametral gegenüberliegende Hakenelemente 7 ausgebildet, die am unteren Rand je einer die Hülsenwandung ganz durchsetzenden öffnung 8 "angewachsen" sind und im unbelasteten Zustand in der aus Figur 2a ersichtlichen Weise über den Aussenumfang der Hülse 6 hinausragen. Die Hakenelemente 7 besitzen Hakenflächen 9, die in dem aus Figur 2a ersichtlichen Zustand den Innenraum der Hülse 6 völlig freilassen.A sleeve, designated as a whole by 6, can be pushed onto the attachment projection 2 (FIGS. 2a, 2b), which may also consist of PVC. In one piece with the sleeve 6, diametrically opposed hook elements 7 are formed, which "grow" at the lower edge of an opening 8 that completely penetrates the sleeve wall and, in the unloaded state, protrude beyond the outer circumference of the sleeve 6 in the manner shown in FIG. 2a. The hook elements 7 have hook surfaces 9, which completely leave the interior of the sleeve 6 in the state shown in FIG. 2a.

Der Innendurchmesser der Hülse 6 ist auf den Aussendurchmesser des Befestigungsansatzes 2 im Bereich der Schulter 5 sowie auch an dessen Fuss unmittelbar in der Nähe des Bodens 3 so abgestimmt, dass die Hülse 6 allenfalls mit geringem Spiel auf den Befestigungsansatz 2 aufschiebbar ist.The inside diameter of the sleeve 6 is matched to the outside diameter of the attachment projection 2 in the region of the shoulder 5 and also at its foot directly in the vicinity of the base 3, so that the sleeve 6 can be pushed onto the attachment projection 2 with little play at best.

In der Nähe des oberen Endes ist die Nocke 10 über einen etwa der Tiefe der Ausnehmung 4 entsprechenden Bereich 13 zylindrisch ausgebildet und im Aussendurchmesser an den Durchmesser der Ausnehmung 4 angepasst. Unterhalb des zylindrischen Bereiches 13 ist eine umlaufende Ringnut 14 als Griffläche zum Einsetzen eines Abziehwerkzeuges vorgesehen.The cam or cam cap 10 according to FIG. 1 has an outer frustoconical shape with a tread surface 11 and with a smooth-walled cylindrical inner recess 12, the diameter of which is slightly larger than the outer diameter of the sleeve 6. In the vicinity of the upper end, the cam 10 is cylindrical over an area 13 corresponding approximately to the depth of the recess 4 and adapted in the outer diameter to the diameter of the recess 4. A circumferential annular groove 14 is provided below the cylindrical region 13 as a gripping surface for inserting a pulling tool.

Zum Befestigen der Nocke 10 an dem Befestigungsansatz 2 wird zunächst die Hülse 6 auf den Befestigungsansatz 2 soweit aufgeschoben, dass der (in Figur 2a) obere Rand der Hülse 6 an dem Boden 3 ansteht. In dieser Stellung befinden sich die Hakenflächen9 der Hakenelemente 7 weitgehend genau in Höhe der Schulter 5, hintergreifen diese jedoch nicht, da sie sich noch unbelastet innerhalb der öffnung 8 befinden. Der Abstand der Hakenflächen 9 von dem oberen Rand der Hülse 6 entspricht somit dem Abstand a der Schulter 5 von dem Boden 3. Wird nunmehr die Nocke 10 auf den Befestigungsansatz 2 bzw. auf die darüber befindliche Hülse 6 aufgeschoben, so werden die Hakenelemente 7 durch die zugeordneten öffnungen 8 der Hülsenwandung hindurch eingeschwenkt, so dass ihre Hakenflächen 9 die Schulter 5 des Befestigungsansatzes 2 hintergreifen. Da aber die bezüglich der Längsachse der Hülse 6 radiale Erstrekkung der Hakenelemente geringfügig grösser ist als die Ringbreite der Schulter 5 und die Dicke der Hülsenwandung zusammen, stehen die Hakenelemente mit ihrem radial inneren Ende an der Aussenfläche des Befestigungsansatzes 2 an während sie noch geringfügig über die Aussenfläche der Hülse 6 hinausragen. Das weitere Aufschieben der Nocke 10 auf die Hülse 6 kann deshalb nur unter einer gewissen örtlichen elastischen Verformung der Hakenelemente 7 und/oder der Innenwandung der Nocke 10 erfolgen. Hierdurch entsteht zwischen dieser Innenwandung und zumindest den Hakenelementen, unter Umständen aber auch einem Teil der an die Hakenelemente anschliessenden Aussenfläche der Hülse 6, ein hoher Reibschluss, durch den die Nocke 10 fest mit der Hülse 6 verbunden ist. Da die Hülse 6 wiederum formschlüssig durch die Hakenelemente 7 an der Schulter 5 gehalten ist, lässt sich die Nocke 10 von dem Befestigungsansatz 2 nur noch entfernen, wenn unter Anwendung einer Abziehkraft, die mindestens der Aufdrückkraft entspricht, die Nocke 10 zuvor von der Hülse 6 wieder abgezogen wird. Die geschilderten Abmessungsverhältnisse von Innenausnehmung 12 und Hakenelementen 7 sind so gewählt, dass die Abzugskraft auf jeden Fall erheblich über der Kraft liegt, die bei der Benutzung des Sportschuhes in Längsrichtung des Befestigungsansatzes 2 zu erwarten ist. Das bedeutet, dass die Nocke 10 zwar auswechselbar, jedoch von selbst nicht lösbar mit dem Befestigungsansatz 2 verbunden ist. Da dieser und auch die Hülse 6 die elastische Nachgiebigkeit des Sohlenmaterials besitzt und die Nocke 10, die vorzugsweise aus einem verschleissfesten Polyurethan besteht, diese Nachgiebigkeit nicht kompensieren kann, erhält man hierdurch eine Nockensohle mit der dafür typischen Nachgiebigkeit der Nocken, wobei die Nocken jedoch nach Verschleiss auswechselbar sind.To fasten the cam 10 to the fastening projection 2, the sleeve 6 is first pushed onto the fastening projection 2 to such an extent that the upper edge of the sleeve 6 (in FIG. 2a) abuts the bottom 3. In this position, the hook surfaces 9 of the hook elements 7 are largely exactly at the level of the shoulder 5, but do not engage behind them, since they are still unloaded within the opening 8. The distance of the hook surfaces 9 from the upper edge of the sleeve 6 thus corresponds to the distance a of the shoulder 5 from the floor 3. If the cam 10 is now pushed onto the fastening projection 2 or onto the sleeve 6 located above it, the hook elements 7 are pushed through the associated openings 8 of the sleeve wall are pivoted in so that their hook surfaces 9 engage behind the shoulder 5 of the fastening projection 2. However, since the radial extension of the hook elements with respect to the longitudinal axis of the sleeve 6 is slightly larger than the ring width of the shoulder 5 and the thickness of the sleeve wall together, the radially inner end of the hook elements lies against the outer surface of the attachment projection 2 while they are still slightly above the The outer surface of the sleeve 6 protrude. The further pushing the cam 10 onto the sleeve 6 can therefore only under a certain location union elastic deformation of the hook elements 7 and / or the inner wall of the cam 10 take place. This results in a high frictional engagement between this inner wall and at least the hook elements, but possibly also a part of the outer surface of the sleeve 6 adjoining the hook elements, by means of which the cam 10 is firmly connected to the sleeve 6. Since the sleeve 6 is in turn held in a form-fitting manner by the hook elements 7 on the shoulder 5, the cam 10 can only be removed from the fastening attachment 2 if the cam 10 has previously been removed from the sleeve 6 using a pull-off force which corresponds at least to the pressing force is withdrawn again. The dimensional relationships of the inner recess 12 and the hook elements 7 are selected such that the pulling force is in any case considerably greater than the force that is to be expected in the longitudinal direction of the fastening attachment 2 when the sports shoe is used. This means that the cam 10 is interchangeable, but is not detachably connected to the fastening projection 2 by itself. Since this and also the sleeve 6 have the elastic flexibility of the sole material and the cam 10, which preferably consists of a wear-resistant polyurethane, cannot compensate for this flexibility, this results in a cam sole with the typical flexibility of the cams, but the cams do Wear can be replaced.

Wie eingangs erwähnt, besteht der besondere Vorteil der hier vorgeschlagenen Lösung weiterhin darin, dass nach dem Verschleiss der Laufseite 11 der Nocke 10 in einem Ausmass, dass die Innenausnehmung 12 freigelegt wird, zwar die Gefahr besteht, dass das freie Ende des Befestigungsansatzes 2 ebenfalls beschädigt wird. Da aber die Schulter 5 sich in einem beträchtlichen Abstand davon befindet, wird die weitere Brauchbarkeit des Befestigungsansatzes.2 nicht gefährdet. Auch die sichere Halterung einer neuen Nocke 10 und gegebenenfalls Hülse 6 wird nicht beeinträchtigt, da die Hülse 6 im Bereich der Schulter 5 und in der Nähe des Bodens 3 abgestützt ist.As mentioned at the beginning, the particular advantage of the solution proposed here is still that that after the running side 11 of the cam 10 has been worn to such an extent that the inner recess 12 is exposed, there is a risk that the free end of the fastening projection 2 will also be damaged. However, since the shoulder 5 is located at a considerable distance from it, the further usability of the fastening approach 2 is not endangered. The secure mounting of a new cam 10 and, if applicable, sleeve 6 is not impaired, since the sleeve 6 is supported in the region of the shoulder 5 and in the vicinity of the base 3.

Um sicherzustellen, dass die Hakenflächen 9 der Hakenelemente 7 sich stets in dem gewünschten Abstand a vom Boden 3 der Ausnehmung 4 befinden, kann daran gedacht werden, das obere Ende der Hülse 6, wie aus Figur 2a ersichtlich ist, dünn auslaufend und daher leicht verformbar auszubilden und überdies den Abstand bis zur Hakenfläche 9 keinesfalls kleiner als den Abstand a zu halten. Hierdurch wird beim Aufschieben der Nocke 10 dieses obere Ende an dem Boden 3 geringfügig elastisch gestaucht, so dass die Hakenelemente 7 die Schulter 5 mit einer leichten Vorspannung hintergreifen.In order to ensure that the hook surfaces 9 of the hook elements 7 are always at the desired distance a from the bottom 3 of the recess 4, it can be considered that the upper end of the sleeve 6, as can be seen in FIG. 2a, runs out thinly and is therefore easily deformable form and moreover the distance to the hook surface 9 is in no way smaller than the distance a. As a result, when the cam 10 is pushed on, this upper end is slightly elastically compressed on the base 3, so that the hook elements 7 engage behind the shoulder 5 with a slight pretension.
