Description

Die Erfindung bezieht sich auf Spender zur portionierten Einzelausgabe von Tabletten, Pasten oder dergleichen.The invention relates to dispensers for portioned individual dispensing of tablets, pastes or the like.

Ein Spender dieser Art ist Gegenstand der nicht vorveröffentlichten EP-A 184 742 der Anmelderin. Dort sind die gezahnten Widerlagerleisten der Gehäuserohrwand angeformt. Die Transportleisten dagegen führen sich in Längsnuten der Gehäuserohrwand. Die Anordnung ist so, daß der gesamte lichte Querschnitt des Gehäuserohres für das Ausgabegut freibleibt. In herstellungstechnischer Hinsicht wäre es dagegen wünschenswert, das Gehäuserohr weitestgehend aus Formmaßnahmen hinsichtlich der die Spendermechanik bildenden Mittel herauszuhalten, es also bei der einfachen glatten Rohrform des Spendergehäuses zu belassen.A donor of this type is the subject of the applicant's unpublished EP-A 184 742. There the toothed abutment strips of the housing tube wall are formed. The transport strips, on the other hand, run in the longitudinal grooves of the housing tube wall. The arrangement is such that the entire clear cross section of the housing tube remains free for the output material. From a manufacturing point of view, on the other hand, it would be desirable to keep the housing tube as far as possible out of shape measures with regard to the means forming the dispenser mechanism, that is, to leave it with the simple, smooth tube shape of the dispenser housing.

Aufgabe der Erfindung ist es, einen gattungsgemäßen Spender bezüglich seiner den Vorschub des Druckbodens bringenden Mittel baulich und montagetechnisch günstiger auszubilden, ohne jedoch die Funktionszuverlässigkeit zu beeinträchtigen.It is the object of the invention to construct a generic dispenser in terms of its means bringing the pressure plate forward in terms of construction and assembly technology, without, however, impairing the functional reliability.

Gelöst ist diese Aufgabe gemäß der Erfindung dadurch, daß die Transportzahnleisten und Widerlagerzahnleisten an einem Einsatzstück des Gehäuserohres sitzen.This object is achieved according to the invention in that the transport toothed strips and abutment toothed strips sit on an insert of the housing tube.

Zufolge solcher Ausgestaltung ist ein gattungsgemäßer Spender einfachen Aufbaues und trotzdem hoher Gebrauchszuverlässigkeit erzielt: Die gesperreartig wirkenden Leisten sind zu einem separaten Bauteil vereinigt. Letzteres läßt sich hülsenartig und daher recht dünnwandig gestalten. Die Montage beschränkt sich auf das Einführen und Zuordnen dieses Einsatzstückes. Das kann vollautomatisch geschehen. Es brauchen nicht mehr einzelne Transportzahnleisten eingelegt zu werden. Auch ist es nicht mehr erforderlich, hinsichtlich der Materialwahl einen Kompromiß einzugehen; vielmehr kann das für den jeweiligen Zweck optimal geeignete Material Verwendung finden. Für die beweglichen Transportleisten werden besondere Führungen entbehrlich; in diesem Zusammenhang bietet sich eine vorteilhafte Lösung dahingehend an, daß die Transportzahnleisten und die Widerlagerzahnleisten durch randseitige Stege untereinander gekuppelt sind. Eine solche Anbindung stellt spritztechnisch kein Problem dar, ist stabil und hat überdies den Vorteil, daß die Stege als Rückstellfedem gestaltet sein können. Hierdurch wird die klassische separate Rückholfeder verzichtbar. Die Teilezahl verringert sich. Eine vor allem gebrauchsvorteilhafte Ausgestaltung ergibt sich endlich dadurch, daß das Einsatzstück entgegen Federbelastung im Gehäuserohr in der der Ausgabeöffnung entgegengesetzten Richtung in einer Art Freigang verlagerbar ist. Diese Maßnahme führt dazu, daß der Druckboden nach Loslassen der Betätigungshandhabe noch ein wenig weiter zurücktritt wodurch das auszugebende Gut sich entspannt; bei pastösem Füllinhalt kommt es dabei nicht und zu dem sonst üblichen ausgabeseitigen Überstand an pastöser Masse. Dieser Überstand wird zufolge der geringen Absenkbewegung des Druckbodens vielmehr eingezogen. Das erhält den FeuchteanschlußAs a result of such an embodiment, a generic dispenser of simple construction and nevertheless high reliability of use is achieved: the bars, which act like a lock, are combined to form a separate component. The latter can be made sleeve-like and therefore quite thin-walled. The assembly is limited to the insertion and assignment of this insert. This can be done fully automatically. It is no longer necessary to insert individual transport toothed strips. It is also no longer necessary to compromise on the choice of materials; rather, the material that is optimally suitable for the respective purpose can be used. Special guides are not required for the movable transport bars; In this context, an advantageous solution offers itself in that the transport toothed strips and the abutment toothed strips are coupled to one another by webs on the edge. Such a connection is not a problem in terms of injection technology, is stable and also has the advantage that the webs can be designed as a return spring. This makes the classic separate return spring unnecessary. The number of parts is reduced. A particularly advantageous embodiment results from the fact that the insert can be displaced against the spring load in the housing tube in the direction opposite to the dispensing opening in a kind of clearance. This measure leads to the pressure floor receding a little further after releasing the actuating handle, whereby the material to be dispensed relaxes; in the case of pasty filling contents, this does not result in the usual excess of pasty mass on the output side. This protrusion is rather drawn in due to the slight lowering movement of the pressure floor. This maintains the moisture connection

Der auf die Ausgabe pastösen Füllinhaltes abgestimmte Spender besitzt ein im wesentlichen zylindrisches Gehäuserohr 1. Letzteres schließt bodenseitig mit einem von unten her einführbaren Druckboden 2 ab. Dieser läßt sich über eine Betätigungshandhabe 3 schrittweise in Richtung des Pfeiles x bewegen.The dispenser, which is matched to the dispensing of pasty filling contents, has an essentially cylindrical housing tube 1. The bottom ends on the bottom side with a pressure base 2 that can be inserted from below. This can be moved gradually in the direction of arrow x via an actuating handle 3.

Oben schließt der Spender mit einer aufschraubbaren Decke 4 ab, welches sich trichterförmig zu einer zentralen Ausgabeöffnung 5 verengt.The dispenser ends at the top with a screw-on ceiling 4, which narrows in a funnel shape to a central dispensing opening 5.

Die Decke 4 steht in Schraubeingriff mit dem zylindrischen Gehäuserohr 1, wozu letzteres im Bereich seines oberen Randes ein Innengewinde 6 trägt, welches mit dem entsprechenden Außengewinde der zu einem Kappenkörper gestalteten Decke 4 zusammenwirkt. Die Kappenwandung 7 formt einen Ringbund 8, der sich auf den oberen Stirnrand 1' des Gehäuserohres 1 anschlagbegrenzend auflegt.The cover 4 is in screw engagement with the cylindrical housing tube 1, for which the latter has an internal thread 6 in the region of its upper edge, which cooperates with the corresponding external thread of the cover 4 designed to form a cap body. The cap wall 7 forms an annular collar 8, which lies on the upper end edge 1 'of the housing tube 1 so as to limit the stop.

Zwischen Druckboden 2 und Decke 4 befindet sich ein die pastöse Masse M enthaltender Sack 9 aus Kunststoff-Folie, -Gewebe oder dergleichen. Dieser hat die Form einer beiderends abgebundenen "Wurst". Er besitzt ebenfalls zylindrische Form und steht, unter Belassung eines mantelseitigen Ringspaltes, praktisch frei aufrecht im Spendergehäuse 1. Von den sogenannten "Wurstzipfeln" ragt das obere, geraffte Sackwandungsende 9' praktisch tüllenartig gefaßt durch die Ausgabeöffnung 5 hindurch, kurz oberhalb welcher es abgetrennt ist. Das andere, mit einer Plombe 10 verschlossengehaltene Sackwandungsende 9" ragt in eine zentrale Vertiefung 11 des Druckbodens 2.Between the pressure base 2 and the ceiling 4 there is a sack 9 containing the pasty mass M made of plastic film, fabric or the like. This has the shape of a "sausage" tied at both ends. It also has a cylindrical shape and, with an annular gap on the casing side, is practically freely upright in the dispenser housing 1. From the so-called "sausage tips", the upper, gathered sack wall end 9 'projects practically like a grommet through the dispensing opening 5, just above which it is separated . The other bag wall end 9 ″, which is closed with a seal 10, projects into a central depression 11 in the pressure base 2.

Das Auspressen der pastösen Masse M aus dem Sack 9 erfolgt über eine handhabenveranlaßte axiale Zugbewegung zweier diametral einander gegenüberliegend angeordneter Transportzahnleisten 12. Deren steilstehende Zahnflanken 12' schleppen den Druckboden 2 in Richtung des Pfeiles x mit. Hierzu gehen vom Druckboden 2 Ratschenzungen 13 aus. Gebildet sind sie von einem Kragen des topfförmig gestalteten Druckbodens. Der Kragen ist zinnenartig unterbrochen, so daß einzelne radial bewegliche Finger vorliegen, welche mit ihren leicht nach auswärts abgewinkelten Enden formschlüssig in die Transportzahnleiste 12 eingreifen. Die flachere Flanke 12" der Transportleisten 12 wird bei Gegenbewegung von den Ratschenzungen 13 frei überlaufen.The pasty mass M is squeezed out of the sack 9 via a manipulated axial pulling movement of two diametrically opposed transport toothed strips 12. Their steep tooth flanks 12 'drag the pressure base 2 in the direction of the arrow x. For this purpose, 2 ratchet tongues 13 start from the pressure floor. They are formed by a collar of the pot-shaped pressure base. The collar is crenellated, so that individual be radial there are movable fingers which engage with their slightly angled ends positively in the transport toothed strip 12. The flatter flank 12 ″ of the transport strips 12 is freely overrun by the ratchet tongues 13 in the event of a counter-movement.

Vom Rücken der sich an der Innenwandfläche des Gehäuserohres 1 geführt abstützenden Transportzahnleisten 12 gehen im oberen Bereich nach auswärts gerichtete Zapfen 14 aus. Letztere durchgreifen eine den maximalen Verlagerungshub der Transportzahnleiste 12 berück sichtigende Durchbrechung 15 der zylindrischen Wandung des Gehäuserohres 1.From the back of the transport toothed strips 12, which are supported on the inner wall surface of the housing tube 1, extend in the upper region outwardly directed pins 14. The latter pass through an opening 15 of the cylindrical wall of the housing tube 1 that takes into account the maximum displacement stroke of the transport toothed strip 12.

Die an den Zahpfen 14 der beiden Transportzahnleisten 12 angreifende Betätigungshandhabe 3 ist als doppelarmiger Hebel gestaltet. Um die diametral einander gegenüberliegenden Zapfen 14 zu fassen, gabelt sich die Betätigungshandhabe wie aus Fig. 5 ersichtlich. Die beiden entsprechend gewölbten Gabelzinken 16 sind an einander gegenüberliegenden Stellen des Gehäuserohres 1 gelagert. Die Lagerstellen tragen das Bezugszeichen 17. Sie liegen außerhalb der Diametralen. Der der seitlich vorstehenden Betätigungshandhaben-Taste 18 gegenüberliegende Endbereich, es handelt sich um den kürzeren Arm des Hebels, ist im Wege der Klipsverbindung mit denZapfen 14 gelenkig gekuppelt. Das freie, gespaltene Ende der Gabelzinken 16 läßt sich dazu entgegen der Rückstellkraft des Materiales auseinanderspreizen und über den verdickten Kopf der Zapfen 14 schnäppern. Der Kopf liegt dann in der einen Vertikalbacke ein, während die gegenüberliegende dem Gehäuserohr 1 zugewandte Vertikalbacke mittels einer Nase 16' den Einfädelweg versperrt.The actuating handle 3 engaging the teeth 14 of the two transport toothed strips 12 is designed as a double-armed lever. In order to grasp the diametrically opposite pins 14, the actuating handle bifurcates as shown in FIG. 5. The two correspondingly curved fork tines 16 are mounted at mutually opposite locations on the housing tube 1. The bearings have the reference number 17. They are outside the diametrals. The end region opposite the actuating handle button 18 protruding to the side, which is the shorter arm of the lever, is articulated by means of the clip connection with the pin 14. The free, split end of the fork tines 16 can be spread apart against the restoring force of the material and snapped over the thickened head of the pin 14. The head then lies in one vertical jaw, while the opposite vertical jaw facing the housing tube 1 blocks the threading path by means of a nose 16 '.

Um ein genügend verklemmungsfreies Bewegungsspiel für die Betätigungshandhabe 3 zu erhalten, ist die Lagerstelle 17, d.h. die einen Gelenkzapfen der Gabelzinken 16 aufnehmende Ausnehmung in der Wandung des Gehäuserohres 1 deutlich größer gewählt, praktisch als horizontaler Längsschlitz 19 realisiert.In order to obtain a sufficiently jam-free movement for the actuating handle 3, the bearing 17, i. the recess in the wall of the housing tube 1 receiving a hinge pin of the fork tines 16 is chosen to be significantly larger, practically implemented as a horizontal longitudinal slot 19.

Den über die Betätigungshandhabe 3 axial verlagerbaren Transportzahnleisten 12 sind in diese Bewegung nicht einbezogene Widerlagerzahnleisten 20 benachbart. Letztere besitzen die gleiche sägezahnartige Struktur wie die Transportzahnleisten. 12, also auch eine steile, d.h. senkrecht zur Verlagerungsrichtung des Druckbodens 2 liegende Flanke 20' und einen überlaufbaren Rücken, der von einer recht flachen Flanke 20" gebildet ist. Die jeweiligen Flanken fluchten in Umlaufrichtung, d.h. die Flanke 12' liegt höhengleich zur Flanke 20' etc.The abutment toothed racks 12 which are axially displaceable via the actuating handle 3 are adjacent to abutment toothed racks 20 which are not included in this movement. The latter have the same sawtooth-like structure as the transport toothed strips. 12, i.e. also a steep, i.e. Flank 20 'perpendicular to the direction of displacement of the pressure base 2 and a back that can be run over, which is formed by a fairly flat flank 20 ". The respective flanks are aligned in the circumferential direction, i.e. the flank 12' is at the same height as the flank 20 'etc.

Die Transportleisten 12 und die in gleicher Winkelverteilung liegenden, ebenfalls axial ausgerichteten Widerlagerleisten 20 sitzen an einem Einsatzstück 21, welches in das Gehäuserohr 1 eingesteckt ist. Das Einsatzstück ist als Hüls gestaltet mit in Umfangsrichtung liegenden quergewölbt stabartigen Elementen. Wie Fig. 3 entnehmbar, sind die Transportzahnleisten 12 und die Widerlagerzahnleisten 20 durch randseitige Stege 22 untereinander gekuppelt. Oben und unten schließt die so gebildete Hülse mit einem durchgehenden Ringkragen 23 bzw. 24 ab. Der obere Ringkragen 23 ist außenseitig bei 25 gefast, so daß das vom Boden her erfolgende Einstecken der Hülse erleichtert ist. Die wie Haltearme wirkenden Stege 22 bringen im übrigen die notwendige Flexiblität im Hinblich auf ein radiales Ausweichen für das Einklipsen der Zapfen 14 in die Gehäuserohr-Durchbrechung 15. Die Stege 22 liegen in der Ringmantelebene der Hülse und treten gegenüber der ein exponierte Lage einnehmenden Verzahnung entsprechend zurück. Sie gehen von den vertikalen Längsrändern der benachbarten Leisten aus. Wie erkennbar, sind die beweglichen Transportzahnleisten 13 praktisch in eine Fensterhöhlung 26 eingehängt. So verbleibt beiderseits ein Abstand y und oberseitig ein gegenüber diesem kleinerer axialer Abstand y' zum nur von den Stegen 22 überbrückten Fensterrahmen. Unten steht das Ende der Transportzahnleiste 12 praktisch in einem einen Lichtspalt entsprechenden Abstand vor dem dortigen Ringkragen 24. Das Maß y' berücksichtigt den für die Transportbetätigung erforderlichen Arbeitshub.The transport strips 12 and the axially aligned abutment strips 20, which are in the same angular distribution, are seated on an insert piece 21 which is inserted into the housing tube 1. The insert is designed as a sleeve with circumferentially arched rod-like elements. As can be seen in FIG. 3, the transport toothed strips 12 and the abutment toothed strips 20 are coupled to one another by edge-side webs 22. Above and below, the sleeve thus formed ends with a continuous ring collar 23 and 24, respectively. The upper ring collar 23 is chamfered on the outside at 25, so that it is easier to insert the sleeve from the bottom. The webs 22, which act as holding arms, also provide the necessary flexibility in terms of radial deflection for the clipping of the pins 14 into the housing tube opening 15. The webs 22 lie in the annular surface plane of the sleeve and correspond to the toothing which occupies an exposed position back. They start from the vertical longitudinal edges of the neighboring strips. As can be seen, the movable transport toothed strips 13 are practically suspended in a window cavity 26. Thus, a distance y remains on both sides and, on the upper side, a smaller axial distance y ′ than the window frame bridged only by the webs 22. At the bottom, the end of the transport toothed strip 12 is practically at a distance corresponding to a light gap in front of the ring collar 24 there. The dimension y 'takes into account the working stroke required for the transport actuation.

Die Stege 22 setzen im wesentlichen in den Endbereichen der Transportzahnleisten 20 an. Sie nehmen, ausgehend von der vertikalen Randkante der Widerlagerzahnleisten 20 zunächst einen rechtspitzwinkligen Verlauf, um dann aber in einer deutlichen Krümmung im wesentlichen senkrecht in die korrespondierende Randkante der Transportzahnleisten 12 einzulaufen.The webs 22 essentially start in the end regions of the transport toothed strips 20. Starting from the vertical marginal edge of the abutment toothed strips 20, they initially take a right-angled course, but then run into the corresponding marginal edge of the transport toothed strips 12 substantially perpendicularly in a clear curvature.

Die Stege 22 erfüllen außer der verbindenden Funktion auch die von Rückstellfedern, so daß nach Loslassen der Betätigungshandhabe 3 stets die Grundstellung der Machnik wieder eintritt. Die entsprechende Federkraft ist so bemessen, daß die Transportzahnleiste 12 aus der angehobenen, den Druckboden 2 nach oben schleppenden Stellung unter Überlaufen der Ratschenzungen 13 wieder in die Ausgangsstellung zurückfährt.In addition to the connecting function, the webs 22 also perform the function of return springs, so that after releasing the actuating handle 3, the basic position of the mechanics always occurs again. The corresponding spring force is dimensioned such that the transport toothed strip 12 moves back from the raised position, dragging the pressure base 2 upward, overflowing the ratchet tongues 13 into the starting position.

Der untere, d.h. standflächenseitige Ringkragen 24 ist in axialer Richtung flexibel gestaltet. Erreicht ist dies durch in Umfangsrichtung verlaufende, durch axiale Stege 27 unterbrochene Längsschlitze 28. In axialer Richtung gesehen, erstrecken sich zwei solcher Längsschlitze 28 hintereinanderliegend. Die Stege 27 sitzen einmal in der Symmetrieebene der Transportzahnleiste 12 und benachbart dazu in der Symmetrieebene der Widerlagerzahnleiste 20. In unbelastetem Zustand federt die Hülse wieder in ihre aus Fig. 3 ersichtliche Ausgangsstellung. Die Last des Ausgabegutes dagegen bewirkt das Zusammenschieben um das Freigangmaß z.The lower, i.e. standing collar collar 24 is designed to be flexible in the axial direction. This is achieved by longitudinal slots 28 which run in the circumferential direction and are interrupted by axial webs 27. Viewed in the axial direction, two such longitudinal slots 28 extend one behind the other. The webs 27 are seated once in the plane of symmetry of the transport toothed rack 12 and adjacent thereto in the plane of symmetry of the abutment rack 20. In the unloaded state, the sleeve springs back into its starting position shown in FIG. 3. The load of the output goods, on the other hand, causes them to be pushed together by the clearance dimension z.

In Grundstellung nimmt dieses Strukturgerippe dabei eine knöchernde Lage ein, d.h. die horizontalen Ringabschnitte legen sich berührend gegen die korrespondieren Längsschlitzflanken (Fig. 7).In the basic position, this structural skeleton occupies an ossified position, i.e. the horizontal ring sections touch against the corresponding longitudinal slot flanks (Fig. 7).

Bei jeder Betätigung wird immer zunächst dieser als Freigang z eingezeichnete Teilhub durchlaufen; erst dann setzt der das Überlaufen der Widerlagerzahnleisten 20 des Zahngesperres bringende Hubabschnitt ein (ca. zwei Zähne), der das Volumen zwischen Druckboden 2 und Decke 4 verringert. Wird die Betätigungshandhabe losgelassen, ziehen sich die Transportzahnleisten 12 unter Unterlaufen der Ratschenzungen 13 wieder in ihre Ausgangslage zurück. Derweil stützt sich der Druckboden 2 an den "örtlichen" Widerlagerzahnleisten 20 ab. Ist die nächste Ratschengrundstellung erreicht, sinkt anschließend das Einsatzstück 21 und mit ihm der sich daran abstützende Druckboden 2 um das Maß des erläuterten Freiganges z nach unten ab. Die Masse M entspannt sich etwas. Letzteres führt zu einem Saugeffekt, der einen etwaigen Paste-Überstand vor der Ausgabeöffnung 5 in den Sack 9 zurücksaugt.Each time this button is actuated, this partial stroke shown as clearance z is always run through; Only then does the lifting section bring about the overflow of the abutment toothed strips 20 of the tooth lock (approx. two teeth), which reduces the volume between the pressure floor 2 and the ceiling 4. If the actuating handle is released, the transport toothed strips 12 pull back into their starting position while underneath the ratchet tongues 13 ge back. Meanwhile, the pressure floor 2 is supported on the "local" abutment toothed strips 20. When the next basic ratchet position is reached, the insert 21 and with it the pressure base 2 supported on it then drops downwards by the amount of the clearance z explained. The mass M relaxes a little. The latter leads to a suction effect which sucks any excess paste in front of the discharge opening 5 into the sack 9.

In der Grundstellung gemäß Fig. 2 ist dieser Effekt noch nicht erreichbar, weil sich dort der Druckboden 2 auf der Standfläche St des Spenders abstützt. Er müßte also hier kürzer geschnitten sein oder man müßte den Erstgebrauch durchführen.In the basic position according to FIG. 2, this effect cannot yet be achieved, because there the pressure floor 2 is supported on the stand area St of the dispenser. It would have to be cut shorter here or you would have to use it for the first time.

Der untere Ringkragen 24 des hülsenförmigen Einsatzstückes 21 ist zugleich auch im Sinne einer unverlierbaren Zuordnung am Gehäuserohr 1 gestaltet; er weist dazu an seiner Mantelfläche eine Ringnut 30 auf, in welche ein Ringwulst 31 des genannten Rohrgehäuses 1 formpassend hineinragt. Dabei ist eine Nutstruktur gewählt, die so groß ist, daß auch noch ein Ringbund 32 eines dem Gehäuserohr 1 zugeordneten Standringes 33 dort seinen Halt findet.The lower ring collar 24 of the sleeve-shaped insert 21 is also designed in the sense of a captive assignment on the housing tube 1; For this purpose, it has an annular groove 30 on its lateral surface, into which an annular bead 31 of said tube housing 1 projects in a form-fitting manner. In this case, a groove structure is chosen which is so large that an annular collar 32 of a stand ring 33 assigned to the housing tube 1 also finds its hold there.

Der Spender besitzt eine Schutzkappe 34. Letztere ist, die Decke 4 domartig überfangend, auf das obere Ende des Gehäuserohres 1 aufgeschraubt, welches das entsprechende Gegengewinde besitzt. In Aufschraubstellung tritt der untere Rand 34' der Schutzkappe 34 sperrend über das freie Ende der Gabelzinken 16 der Betätigungshandhabe 3, so daß der Spender bei ordnungsgemäß aufgeschraubter Schutzkappe 34 gegen Ausgabe gesperrt ist. Den Schraubbegrenzungsanschlag bildet ein Ringbund 35, welcher, in Schaffung eines Ausweichraumes für den kürzeren Hebelarm im Bereich des den kürzeren Hebelarm bildenden Abschnitts der Betätigungshandhabe 3 eine nach oben offene Durchbrechung 36 formt.The dispenser has a protective cap 34. The latter, covering the ceiling 4 like a dome, is screwed onto the upper end of the housing tube 1, which has the corresponding counter thread. In the unscrewed position, the lower edge 34 'of the protective cap 34 locks over the free end of the fork prongs 16 of the actuating handle 3, so that the dispenser is blocked against dispensing when the protective cap 34 is properly screwed on. The screw limiting stop is formed by an annular collar 35 which, in the creation of a space for the shorter lever arm in the region of the section of the actuating handle 3 forming the shorter lever arm, forms an opening 36 which is open at the top.
