The hanger 3 is thus wound up almost over its entire length L to form the spiral spring 4 .
  • a longer straight shank section 3c, as in figure 1 shown, can have packaging advantages, among other things, since several toilet baskets 1 can be nested in one another in a blister pack in such a way that the housing 2 of one toilet basket 1 comes to lie in the region of the straight shaft section 3c of the second toilet basket 1.

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines WC-Körbchens mit einem Gehäuse für die Aufnahme eines Hygieneprodukts sowie einem Hänger für die Befestigung des WC-Körbchens an einem Rand einer Toilettenschüssel.The present invention relates to a method for producing a toilet basket with a housing for receiving a hygiene product and a hanger for attaching the toilet basket to an edge of a toilet bowl.

Gattungsgemäße WC-Körbchen sind bekannt und dienen der Aufnahme eines Hygieneprodukts, beispielsweise eines festen, pulverförmigen oder gelförmigen Produkts, welches der Desinfektion, Reinigung und/oder Beduftung dient. Das befüllte WC-Körbchen wird dabei mithilfe des Hängers derart über den Rand einer Toilettenschüssel gehängt, dass das Gehäuse auf der Innenseite der Toilettenschüssel unmittelbar unterhalb des Spülrandes zu liegen kommt. Bei Betätigung der Toilettenspülung läuft Wasser entlang des Spülrandes in die Toilettenschüssel und durchspült dabei auch das mit geeigneten Öffnungen versehene Gehäuse des WC-Körbchens. Hierdurch wird bei jedem Spülvorgang eine gewisse Menge des in dem Gehäuse bevorrateten Hygieneprodukts gelöst und dem Spülwasser beigemischt.Generic toilet baskets are known and are used to hold a hygiene product, for example a solid, powdery or gel-like product, which is used for disinfection, cleaning and/or scenting. The filled toilet basket is hung over the edge of a toilet bowl with the help of the hanger in such a way that the housing comes to rest on the inside of the toilet bowl directly below the flushing rim. When the toilet is flushed, water runs along the flushing rim into the toilet bowl and also flushes through the housing of the toilet basket, which is provided with suitable openings. As a result, a certain amount of the hygiene product stored in the housing is dissolved and mixed with the rinsing water during each rinsing process.

Bekannte WC-Körbchen weisen dabei in der Regel einen einteiligen Hänger mit einem geraden Schaft auf, an dessen dem Gehäuse abgewandten Ende ein Haken angeformt ist, welcher sich zur Befestigung über den Rand der Toilettenschüssel legen lässt. Nachteilig ist dabei, dass die Länge des Schafts unveränderlich ist und daher keine Anpassung an unterschiedliche Toilettengeometrien, insbesondere an unterschiedliche Randhöhen, vorgenommen werden kann. Bei einem sehr niedrigen Rand hängt das Gehäuse weit unterhalb des Spülrandes, wodurch das WC-Körbchen insgesamt nicht stabil hängt. Ist der Rand umgekehrt besonders hoch, so lässt sich das Gehäuse unter Umständen nicht unterhalb des Spülrandes anordnen sondern hängt im Bereich des Randes, wo es nicht ausreichend von Wasser umspült wird. Zudem hängt das WC-Körbchen auch in diesem Falle nicht stabil und könnte sich beispielsweise beim Öffnen der Toilettenbrille lösen und in das WC fallen.Known toilet baskets generally have a one-piece hanger with a straight shaft, at the end of which facing away from the housing a hook is formed which can be placed over the edge of the toilet bowl for attachment. The disadvantage here is that the length of the shaft is unchangeable and it is therefore not possible to adapt it to different toilet geometries, in particular to different edge heights. With a very low rim, the housing hangs far below the flush rim, which means that the toilet basket does not hang stably overall. Conversely, if the edge is particularly high, the housing may not be able to be arranged below the flushing edge, but hangs in the area of the edge where it is not sufficiently flushed with water. In addition, the toilet basket does not hang stably in this case either and could, for example, come loose when the toilet seat is opened and fall into the toilet.

Um diesen Nachteilen zu begegnen wurden bereits Hänger für WC-Körbchen vorgeschlagen, die zweiteilig ausgebildet sind. Die beiden Teile eines solchen Hängers können über einen Rastmechanismus miteinander verbunden sein, der verschiedene Einstellmöglichkeiten bietet und so eine gewisse Längenanpassung an unterschiedliche Toilettenränder ermöglicht. Derartige zweiteilige Hänger sind jedoch deutlich aufwendiger in der Herstellung und daher kostenintensiver. Zudem muss ein Nutzer den zweiteiligen Hänger an die Maße seiner Toilette anpassen. Hierzu muss der Nutzer unter Umständen mehrmals in die Toilettenschüssel hineingreifen und den Hänger positionieren, bis die richtige Längeneinstellung gefunden ist. Dies wird als unhygienisch und daher als nachteilig empfunden.In order to counteract these disadvantages, hangers for toilet baskets that are designed in two parts have already been proposed. The two parts of such a hanger can be connected to one another via a locking mechanism that offers various adjustment options and thus allows a certain length adjustment to different toilet rims. However, such two-part hangers are significantly more complex to produce and therefore more expensive. In addition, a user has to adapt the two-piece hanger to the dimensions of his toilet. For this the user may have to reach into the toilet bowl and position the hanger several times until the correct length adjustment is found. This is perceived as unhygienic and therefore disadvantageous.

Die Aufgabe der vorliegenden Erfindung liegt daher in der Bereitstellung eines WC-Körbchens, welches eine Anpassung an unterschiedliche Toilettengeometrien erlaubt und gleichzeitig günstig in der Herstellung und einfach im Gebrauch ist. Eine weitere Aufgabe der Erfindung liegt in der Bereitstellung eines Verfahrens zur Herstellung eines solchen WC-Körbchens.The object of the present invention is therefore to provide a toilet basket that allows adaptation to different toilet geometries and at the same time is inexpensive to manufacture and easy to use. A further object of the invention is to provide a method for producing such a toilet basket.

Diese Aufgaben werden durch ein Verfahren nach Anspruch 1 gelöst.These objects are solved by a method according to claim 1.

Gemäß Patentanspruch 1 umfasst das WC-Körbchen ein Gehäuse für die Aufnahme eines Hygieneprodukts sowie einen an das Gehäuse angrenzenden Hänger einer Länge L zur Befestigung an einem Rand einer Toilettenschüssel, wobei der Hänger ein dem Gehäuse zugewandtes Ende und ein dem Gehäuse abgewandtes Ende aufweist und wobei der Hänger ausgehend von seinem dem Gehäuse abgewandten Ende zu einer Spiralfeder aufgewickelt ist.According to claim 1, the toilet basket comprises a housing for accommodating a hygiene product and a hanger of a length L adjacent to the housing for attachment to an edge of a toilet bowl, the hanger having an end facing the housing and an end facing away from the housing and wherein the hanger is wound starting from its end facing away from the housing to form a spiral spring.

Vorzugsweise hat die Spiralfeder die Form einer Spirale, besonders bevorzugt einer archimedischen Spirale, oder beispielsweise einer logarithmischen Spirale oder einer hyperbolischen Spirale, oder von Variationen davon.Preferably the coil spring is in the form of a helix, more preferably an Archimedean helix, or for example a logarithmic helix or a hyperbolic helix, or variations thereof.

Die Aufwicklung des Hängers zu einer Spiralfeder erlaubt eine einfache Anpassung des WC-Körbchens an unterschiedliche Toilettengeometrien, insbesondere an unterschiedliche Randhöhen, wobei hierzu beispielsweise der Hänger mit der aufgewickelten Spiralfeder über den Toilettenrand gelegt wird und anschließend das Gehäuse gegen die Rückstellkraft der Spiralfeder innerhalb der Toilettenschüssel so weit nach unten gezogen wird, bis es unterhalb des Spülrandes zu liegen kommt, oder das Gehäuse in der Toilette, unterhalb des Spülrandes platziert wird und der aufgewickelte Hänger über den Toilettenrand gezogen wird. Die Spiralfeder wird dabei zumindest teilweise entrollt und spannt das Gehäuse schließlich aufgrund der rückstellenden Federkraft sicher in der Position unterhalb des Spülrandes fest. Der verbleibende, nicht entrollte Teil der Spiralfeder wirkt als Haken, mit dem der Hänger am oberen Rand der Toilettenschüssel fixiert wird. Von besonderem Vorteil ist dabei die Möglichkeit der kontinuierlichen Längenanpassung, da die Spiralfeder zwischen einem Minimal- und einem Maximalwert auf eine beliebige Länge entrollt werden kann. Unabhängig von der Längeneinstellung wirkt dabei stets die rückstellende Federkraft der Spiralfeder, durch die das Gehäuse unterhalb des Spülrandes festgespannt wird. Auf diese Weise kann für zahlreiche Toilettengeometrien und Randhöhen ein optimaler Sitz und Halt des WC-Körbchens unterhalb des Spülrandes erreicht werden.The winding of the hanger into a spiral spring allows the toilet basket to be easily adapted to different toilet geometries, in particular to different rim heights. For this purpose, for example, the hanger with the wound spiral spring is placed over the toilet rim and then the housing is placed inside the toilet bowl against the restoring force of the spiral spring is pulled down until it comes to rest below the rim of the flush, or the housing is placed in the toilet below the rim of the flush and the coiled hanger is pulled over the rim of the toilet. The spiral spring is at least partially unrolled and finally clamps the housing securely in the position below the flushing rim due to the restoring spring force. The remaining, uncoiled portion of the coil spring acts as a hook that secures the hanger to the top of the toilet bowl. Of particular advantage is the possibility of continuous length adjustment, since the spiral spring can be unrolled to any length between a minimum and a maximum value. Irrespective of the length setting, the restoring spring force of the spiral spring always acts, by which the housing is clamped below the flushing rim. To this In this way, an optimal fit and hold of the toilet basket below the flushing rim can be achieved for numerous toilet geometries and rim heights.

Zudem kann die Anpassung an den Toilettenrand in einem einzigen Schritt erfolgen, das heißt, ein Nutzer muss lediglich einmal in den Bereich der Toilettenschüssel hineingreifen, um das Gehäuse zu platzieren, bzw. durch Entrollen und damit Vorspannen der Spiralfeder unmittelbar unterhalb des Spülrandes zu positionieren. Er hält hierzu beispielsweise mit einer Hand den Hänger im Bereich der Spiralfeder in einem außenseitigen Bereich des oberen Randes der Toilettenschüssel fest und zieht das Gehäuse mit der anderen Hand auf der Innenseite der Toilettenschüssel nach unten, bis es unterhalb des Spülrandes zu liegen kommt und sich dort verrastet, oder er platziert und hält mit einer Hand das Gehäuse unterhalb des Spülrandes auf der gewünschten Position fest und zieht mit der anderen Hand den Hänger an der Spiralfeder über den Toilettenrand hinaus um den oberen Rand der Toilettenschüssel hinaus, so dass der verbleibende Hänger in einem außenseitigen Bereich des oberen Randes der Toilettenschüssel verrastet. Die Spiralfeder entrollt sich dabei um eine gewisse, von der Höhe des Toilettenrandes abhängige Länge. Der verbleibende, nicht entrollte Teil der Spiralfeder drückt von außen gegen den Rand der Toilettenschüssel. Ein mehrfaches Hineingreifen in die Toilettenschüssel zwecks optimaler Justierung entfällt.In addition, the adjustment to the toilet rim can be done in a single step, i.e. a user only has to reach into the area of the toilet bowl once to place the housing, or to position it directly below the flushing rim by unrolling and thus pretensioning the spiral spring. For example, he holds the hanger in the area of the spiral spring in an outside area of the upper edge of the toilet bowl with one hand and pulls the housing down with the other hand on the inside of the toilet bowl until it comes to rest below the flushing rim and settles there into place, or he places and holds the housing in the desired position below the flushing rim with one hand and with the other hand pulls the hanger on the spiral spring over the toilet rim and around the upper edge of the toilet bowl, so that the remaining hanger in one outside area of the upper edge of the toilet bowl locked. The spiral spring unrolls by a certain length, which depends on the height of the toilet rim. The remaining part of the spiral spring that has not been unrolled presses against the rim of the toilet bowl from the outside. Reaching into the toilet bowl multiple times for optimal adjustment is no longer necessary.

Die Wickelachse der Spiralfeder, d.h. diejenige Achse, um welche die Spiralfeder aufgewickelt ist, liegt im Wesentlichen senkrecht zur Längserstreckung des Hängers.The winding axis of the coil spring, i.e. the axis about which the coil spring is wound, is substantially perpendicular to the length of the hanger.

Der Hänger ist bevorzugt im nicht eingesetzten Zustand mindestens über die Hälfte seiner Länge L als Spiralfeder aufgewickelt. Gemäß einer weiteren Ausbildung ist der Hänger im nicht eingesetzten Zustand mindestens über Dreiviertel seiner Länge L als Spiralfeder auf gewickelt. Mit anderen Worten ist der Hänger über einen Großteil seiner Länge als Spiralfeder ausgebildet ist. An den als Spiralfeder aufgewickelten Längenabschnitt des Hängers kann sich im Bereich des dem Gehäuse zugewandten Endes des Hängers ein gerader Schaftabschnitt anschließen.When not in use, the hanger is preferably wound up as a spiral spring over at least half of its length L. According to a further embodiment, when not in use, the hanger is wound up as a spiral spring over at least three quarters of its length L. In other words, the hanger is designed as a spiral spring over a large part of its length. A straight shank section can be connected to the longitudinal section of the hanger wound up as a spiral spring in the region of the end of the hanger facing the housing.

Der Hänger kann einteilig ausgebildet sein. Dies ist fertigungstechnisch von Vorteil und senkt somit die Herstellungskosten. Gemäss der vorliegenden Erfindung wird der Hänger aber aus einer gereckten und einer ungereckten Folie hergestellt.The hanger can be made in one piece. This is advantageous in terms of manufacturing technology and thus reduces the manufacturing costs. According to the present invention, however, the hanger is made from a stretched and a non-stretched film.

Es können auch das Gehäuse und der Hänger einteilig ausgebildet sein, d.h. der Hänger wird zusammen mit dem Gehäuse und an dieses fest angeformt in einem gemeinsamen Fertigungsschritt hergestellt. Gemäss der vorliegenden Erfindung sind das Gehäuse und der Hänger als zwei einzelne Teile hergestellt, d.h. der Hänger wird separat von dem Gehäuse gefertigt und anschließend mit dem Gehäuse verbunden.The housing and the hanger can also be designed in one piece, ie the hanger is manufactured together with the housing and is integrally formed on it in a common production step. According to the present invention, the housing and the hanger are manufactured as two separate parts, ie the hanger is manufactured separately from the housing and subsequently with it connected to the housing.

Gemäß der Erfindung wird der Hänger durch Lamination einer gereckten und einer ungereckten Folie hergestellt. Dazu werden zunächst die beiden unterschiedlichen Folien aufeinander gebracht. Die gewünschte Form des Hängers wird sodann aus diesem Folienverbund ausgestanzt. Durch anschließende Aktivierung mittels Wärme zieht sich die gereckte Folie zusammen, wodurch sich im Verbund mit der ungereckten Folie die Spiralfeder ausbildet. Der solchermaßen gefertigte Hänger wird schließlich mit einem Gehäuse verbunden.According to the invention, the hanger is made by laminating a stretched film and an unstretched film. To do this, the two different foils are first placed on top of each other. The desired shape of the hanger is then punched out of this composite film. Subsequent activation by means of heat causes the stretched film to contract, resulting in the formation of the spiral spring in combination with the unstretched film. The hanger manufactured in this way is finally connected to a housing.

In Figur 1 ist ein im Ganzen mit 1 bezeichnetes WC-Körbchen dargestellt. Es umfasst ein Gehäuse 2, welches der Aufnahme eines Hygieneprodukts dient. Hierbei kann es sich beispielsweise um ein festes oder pulverförmiges oder gelförmiges Produkt handeln. Zur Befüllung des Gehäuses 2 mit dem Hygieneprodukt kann das Gehäuse 2 geöffnet werden. Über in den Figuren nicht dargestellte Öffnungen bzw. Durchbrüche in der Wand des Gehäuses 2 kann Wasser in das Gehäuse 2 eintreten und in dem Wasser gelöstes Hygieneprodukt kann wieder aus dem Gehäuse 2 austreten.In figure 1 a designated as a whole with 1 toilet basket is shown. It includes a housing 2, which is used to hold a hygiene product. This can be, for example, a solid or powdery or gel-like product. The housing 2 can be opened to fill the housing 2 with the hygiene product. Water can enter the housing 2 via openings or openings in the wall of the housing 2, which are not shown in the figures, and hygiene product dissolved in the water can exit the housing 2 again.

An dem Gehäuse 2 ist ein Hänger 3 angeformt, der der Befestigung des WC-Körbchens 1 an einem Rand einer Toilettenschüssel dient. Der Hänger 3 weist ein dem Gehäuse 2 zugewandtes Ende 3a und ein dem Gehäuse 2 abgewandtes Ende 3b auf. Ausgehend von seinem dem Gehäuse 2 abgewandten Ende 3b ist der Hänger 3 zu einer Spiralfeder 4 aufgewickelt. Im vollkommen entrollten Zustand weist der Hänger 3 zwischen dem Ende 3a und dem Ende 3b eine Länge L auf. Die Länge L kann beispielsweise etwa 20 cm betragen. Über mehr als Dreiviertel seiner Länge L ist der Hänger 3 in der Figur 1 als Spiralfeder aufgewickelt. Lediglich in dem an das Ende 3a angrenzenden Bereich verbleibt ein gerader Schaftabschnitt 3c, längs dessen der Hänger 3 nicht aufgerollt ist.A hanger 3 is formed on the housing 2 and is used to fasten the toilet basket 1 to an edge of a toilet bowl. The hanger 3 has an end 3a facing the housing 2 and an end 3b facing away from the housing 2 . Starting from its end 3b facing away from the housing 2 , the hanger 3 is wound into a coil spring 4 . In the fully unrolled state, the hanger 3 has a length L between the end 3a and the end 3b. The length L can be about 20 cm, for example. The trailer 3 is in the over more than three-quarters of its length L figure 1 wound up as a spiral spring. Only in the area adjacent to the end 3a remains a straight shank section 3c, along which the hanger 3 is not rolled up.

Figur 2 zeigt ein weiteres WC-Körbchens 1. Es entspricht im Wesentlichen dem in Figur 1 dargestellten WC-Körbchen, mit dem einzigen Unterschied, dass der gerade Schaftabschnitt 3c kürzer ausgebildet ist. Dies hat zur Folge, dass der zu einer Spiralfeder 4 aufgewickelte Teil des Hängers 3 nahezu bis an das Gehäuse 2 heranreicht. Der Hänger 3 ist damit nahezu über seine gesamte Länge L zur Spiralfeder 4 aufgewickelt. Ein länger ausgebildeter gerader Schaftabschnitt 3c, wie in Figur 1 gezeigt, kann unter anderem verpackungstechnische Vorteile haben, da in einer Blisterpackung mehrere WC-Körbchen 1 derart ineinander geschachtelt werden können, dass das Gehäuse 2 des einen WC-Körbchens 1 im Bereich des geraden Schaftabschnitts 3c des zweiten WC-Körbchens 1 zu liegen kommt. Auf diese Weise ist eine dichte Packung möglich. Die Länge des geraden Schaftabschnitts 3c kann sich dabei an den Abmessungen des Gehäuses 2 orientieren. figure 2 shows another toilet basket 1. It essentially corresponds to that in figure 1 shown toilet basket, with the only difference that the straight shaft portion 3c is shorter. The consequence of this is that the part of the hanger 3 wound up to form a spiral spring 4 almost reaches the housing 2 . The hanger 3 is thus wound up almost over its entire length L to form the spiral spring 4 . A longer straight shank section 3c, as in figure 1 shown, can have packaging advantages, among other things, since several toilet baskets 1 can be nested in one another in a blister pack in such a way that the housing 2 of one toilet basket 1 comes to lie in the region of the straight shaft section 3c of the second toilet basket 1. Dense packing is possible in this way. The length of the straight shaft section 3c can be based on the dimensions of the housing 2.

Der Hänger 3 ist derart zur Spiralfeder 4 aufgewickelt, dass die Spiralfeder 4 in der in den Figuren 1 und 2 gezeigten Ruhelage, d.h. im nicht eingesetzten Zustand, etwa 3 vollständige Windungen aufweist.The hanger 3 is wound up to form the coil spring 4 in such a way that the coil spring 4 is in the Figures 1 and 2 rest position shown, ie when not in use, has about 3 complete turns.

Bei dem WC-Körbchen 1 gemäß den Figuren 1 und 2 sind der Hänger 3 und das Gehäuse 2 einteilig ausgebildet und in einem Spritzgussverfahren aus einem geeigneten Kunststoff hergestellt. Dazu weist die Spritzgussform bereits eine Spiralform auf. Dieses Verfahren ist vom Anspruch 1 nicht gedeckt.In the toilet basket 1 according to Figures 1 and 2 the hanger 3 and the housing 2 are designed in one piece and are made of a suitable plastic in an injection molding process. For this purpose, the injection mold already has a spiral shape. Claim 1 does not cover this method.

Die Figuren 3 und 4 zeigen ein WC-Körbchen 1 in Einsatzlage befestigt am Rand 5 einer Toilettenschüssel 6. Dabei ist in Figur 3 ein Ausschnitt einer Toilettenschüssel 6 mit einem Rand 5 einer Höhe H1 dargestellt, während die Figur 4 einen Ausschnitt aus einer Toilettenschüssel 6 mit einem Rand 5 einer Höhe H2 zeigt. Die Höhe H1 ist größer als die Höhe H2.the Figures 3 and 4 show a toilet basket 1 in the position of use attached to the edge 5 of a toilet bowl 6. It is in figure 3 a section of a toilet bowl 6 with shown an edge 5 of a height H1, while the figure 4 shows a section of a toilet bowl 6 with an edge 5 of a height H2. The height H1 is greater than the height H2.

Zur Befestigung des WC-Körbchens 1 an dem Rand 5 der Toilettenschüssel 6 wird der zur Spiralfeder 4 aufgewickelte Teil des Hängers 3 gemäß den Darstellungen der Figuren 3 und 4 in einem außenseitigen Bereich 7 des Randes 5 festgehalten, während das Gehäuse 2 auf der Innenseite der Toilettenschüssel 6 gegen die rückstellende Kraft der Spiralfeder 4 entlang des Randes 5 nach unten gezogen wird, bis es unterhalb eines Spülrandes 8 der Toilettenschüssel 6 zur Anlage kommt. Der zu der Spiralfeder 4 aufgewickelte Teil des Hängers 3 entrollt sich dabei, wobei er sich umso mehr entrollt, je höher der Rand 5 der Toilettenschüssel 6 ist.To attach the toilet basket 1 to the edge 5 of the toilet bowl 6, the spiral spring 4 is wound into the part of the hanger 3 according to the illustrations Figures 3 and 4 held in an outside area 7 of the rim 5, while the housing 2 on the inside of the toilet bowl 6 is pulled downwards along the rim 5 against the restoring force of the coil spring 4 until it comes to rest below a flushing rim 8 of the toilet bowl 6. The part of the hanger 3 wound up to form the coil spring 4 unrolls, the higher the edge 5 of the toilet bowl 6 being, the more it unrolls.

Ein Vergleich der Figuren 3 und 4 zeigt, dass bei einem Rand 5 mit großer Höhe H1 ein längerer Abschnitt der Spiralfeder 4 des Hängers 3 entrollt wird als bei einem Rand 5 mit geringerer Höhe H2. Entsprechend verbleibt bei einem Rand 5 mit geringerer Höhe H2 ein längerer Abschnitt des Hängers 3 zur Spiralfeder 4 aufgewickelt als bei einem Rand 5 mit größerer Höhe H1. Die Aufwicklung des Hängers 3 zu einer Spiralfeder 4 erlaubt somit eine flexible und kontinuierliche Anpassung an unterschiedliche Randhöhen von Toilettenschüsseln 6. Durch die rückstellende Kraft der Spiralfeder 4 in Einsatzlage des WC-Körbchens 1 ist ein fester und stabiler Sitz des WC-Körbchens 1 sichergestellt.A comparison of Figures 3 and 4 shows that a longer section of the spiral spring 4 of the hanger 3 is unrolled with an edge 5 with a large height H1 than with an edge 5 with a smaller height H2. Correspondingly, with an edge 5 with a lower height H2, a longer section of the hanger 3 remains wound up to form the spiral spring 4 than with an edge 5 with a greater height H1. The winding of the hanger 3 into a spiral spring 4 thus allows a flexible and continuous adjustment to different edge heights of toilet bowls 6. The restoring force of the spiral spring 4 in the position of use of the toilet basket 1 ensures a firm and stable seat of the toilet basket 1.
