  • the present invention relates to lattice boxes for transporting liquefied gas containers, but also from other containers, and more particularly relates to a locking device which interacts with the lattice box and which has a crossbar as a frontal locking bar for locking or releasing a loading opening formed in a side wall of the box and on the box has to be arranged holding elements for receiving and holding the locking rod.
  • Such lattice boxes for liquefied gas containers and closing systems for the lattice box are known.
  • Your locking system comprises a metal cross bar held in metal receiving sleeves.
  • the known locking systems prove to be susceptible in that their most stressed parts, namely the locking rod and the receiving sleeves, which hold the rod at their ends, are subject to wear that leads to inoperability.
  • the inoperability is caused by an increasing deformation of the metallic parts or elements of the conventional locking system in that the often very heavy loading of the mesh box hits and / or rubs against the locking bar, whereby not only the impacts against the locking bar deform the bar itself, but in addition to the bumps against the breech rod, the friction on the breech rod deforming bumps of the breech rod against its receiving sleeves and thus gradually bring about a progressive state of deformation of all of these particularly stressed parts until they become unusable.
  • the applicant of the present invention first sought to counteract this problem by first developing prototypes of closure systems in a constant search for methods, model modifications and material changes which could eliminate the known disadvantageous phenomena, one type of which is distinguished in that the closure rod is not made of metal but of a plastic material that gives the rod an exceptional strength and a permanent bending strength and undeformability in practical use.
  • the above-mentioned development nonetheless has metallic sliding sleeves arranged at the ends of the locking rod which can be moved along the vertical sides of a lattice box in the region of their loading and unloading opening, and on the other hand contains a system which is distinguished by a cable or rope which runs vertically and parallel to the corner bars of the lattice box and is attached with its ends to the outside of said corner bars.

  • the invention has great advantages in that not only for the closing device composed of the two sliding holding elements and the locking rod, but preferably also for the lattice box itself, no metallic building material is used and only plastic material is used.

Abstract

Skeleton boxes for liquefied gas containers conventionally have a loading opening formed in one side wall of the box and, as a closing device, a metal closure rod which divides the loading opening transversely and is held in metal bushes. However, the use of metal leads to a progressive deformation of these metal parts, due to the gas containers knocking against the closure rod, up to non-functionability of the closing device. According to the invention, such wear is ruled out by a rigid design of the closure rod (5) and of the holding elements (1, 1') made of plastic material. The closing device is composed of a closure rod (5) which is preferably T-shaped in cross-section and two holding elements (1, 1') which are fitted over it in mirror image and are placed with a U-shaped hooked part 2 against a longitudinal bar (6) of the skeleton box (8) in each case. The closing device (1, 5, 1') which holds itself together is operated by displacing it along the longitudinal bars (6), devices serving for bounding (7) the displacement path towards the bottom and for retention (9) in the uppermost position. The skeleton box (8) is preferably likewise made of plastic in a rigid design. <IMAGE>

Freigabe einer in einer Seitenwand der Kiste ausgebildeten Ladeöffnung und an der Kiste anzuordnende Halteelemente zur Aufnahme und Halterung der Verschlußstange aufweist.The present invention relates to lattice boxes for transporting liquefied gas containers, but also from other containers, and more particularly relates to a locking device which interacts with the lattice box and which has a crossbar as a frontal locking bar for locking or releasing a loading opening formed in a side wall of the box and on the box has to be arranged holding elements for receiving and holding the locking rod.

Derartige Gitterkisten für Flüssiggasbehälter und Verschließsysteme für die Gitterkiste sind bekannt. Ihr Verschließsystem umfaßt eine in metallenen Aufnahmehülsen gehaltene Querstange aus Metall. Die bekannten Verschließsysteme erweisen sich dadurch als anfällig, daß ihre am meisten beanspruchten Teile, nämlich die Verschlußstange und die Aufnahmehülsen, welche die Stange an ihren Enden halten, einem bis zur Funktionsuntüchtigkeit führenden verschleiß unterliegen. Die Funktionsuntüchtigkeit wird durch eine zunehmende Verformung der metallischen Teile oder Elemente des konventionellen Verschließsystems dadurch bedingt, daß die oft sehr schwere Beladung der Gitterkiste gegen die Verschlußstange schlägt und/oder an ihr reibt, wobei nicht nur die Stöße gegen die Verschlußstange die Stange selbst deformieren, sondern außer den Stößen gegen die Verschlußstange auch die Reibungen an der Verschlußstange verformende Stöße der Verschlußstange gegen deren Aufnahmehülsen bewirken und so allmählich einen bis zur Unbrauchbarkeit fortschreitenden Verformungszustand sämtlicher dieser besonders beanspruchten Teile herbeiführen.Such lattice boxes for liquefied gas containers and closing systems for the lattice box are known. Your locking system comprises a metal cross bar held in metal receiving sleeves. The known locking systems prove to be susceptible in that their most stressed parts, namely the locking rod and the receiving sleeves, which hold the rod at their ends, are subject to wear that leads to inoperability. The inoperability is caused by an increasing deformation of the metallic parts or elements of the conventional locking system in that the often very heavy loading of the mesh box hits and / or rubs against the locking bar, whereby not only the impacts against the locking bar deform the bar itself, but in addition to the bumps against the breech rod, the friction on the breech rod deforming bumps of the breech rod against its receiving sleeves and thus gradually bring about a progressive state of deformation of all of these particularly stressed parts until they become unusable.

Diesem Problem suchte die Anmelderin der vorliegenden Erfindung zunächst dadurch entgegenzuwirken, daß sie in ständiger Suche nach Verfahren, Modellabwandlungen und Materialänderungen, welche die bekannten nachteiligen Erscheinungen beseitigten könnten, zunächst Prototypen von Verschließsystemen entwickelt hat, von denen sich eine Art dadurch auszeichnet, daß die Verschlußstange nicht aus Metall sondern aus einem Kunststoffmaterial hergestellt ist, das der Stange eine außergewöhnliche Festigkeit und eine im praktischen Gebrauch dauerhafte Biegefestigkeit und Undeformierbarkeit verleiht. Die genannte Entwicklung weist nichtsdestoweniger an den Enden der Verschlußstange angeordnete metallische Gleithülsen auf, welche sich entlang der vertikalen Seiten einer Gitterkiste im Bereich deren Lade- und Entnahmeöffnung bewegen lassen, und enthält andererseits ein System eingebaut, das sich durch ein Kabel oder Seil auszeichnet, welches vertikal und parallel zu den Eckstäben der Gitterkiste verläuft und mit seinen Enden an der Außenseite der genannten Eckstäbe befestigt ist. Demzufolge lassen sich die Gleithülsen entlang der vertikalen Ecken der Kiste und gleichzeitig entlang der vertikalen und zu den vertikalen Ecken parallelen Seilen derart bewegen, daß die Stange unter Aufrechterhaltung ihrer vollständigen Bewegbarkeit immer an der Kiste angebracht ist. Obwohl sich diese Ausführung im praktischen Gebrauch als wesentlich dauerhafter als die bekannten Verschließsysteme erwiesen hat, blieb aber auch dieses neue System auf die Dauer vor Verformungen und Schäden, insbesondere durch einen Verschleiß der Hülsen oder durch einen Bruch des Führungsseils, nicht verschont.The applicant of the present invention first sought to counteract this problem by first developing prototypes of closure systems in a constant search for methods, model modifications and material changes which could eliminate the known disadvantageous phenomena, one type of which is distinguished in that the closure rod is not made of metal but of a plastic material that gives the rod an exceptional strength and a permanent bending strength and undeformability in practical use. The above-mentioned development nonetheless has metallic sliding sleeves arranged at the ends of the locking rod which can be moved along the vertical sides of a lattice box in the region of their loading and unloading opening, and on the other hand contains a system which is distinguished by a cable or rope which runs vertically and parallel to the corner bars of the lattice box and is attached with its ends to the outside of said corner bars. As a result, the sliding sleeves can be moved along the vertical corners of the box and at the same time along the vertical cables parallel to the vertical corners in such a way that the rod is always attached to the box while maintaining its complete mobility. Although this design has proven to be much more durable than the known closing systems in practical use, this new system was not spared in the long run from deformation and damage, in particular due to wear of the sleeves or breakage of the guide rope.

Aufgabe der Erfindung ist es, die eingangs geschilderten Nachteile der konventionellen Verschließsysteme für Gitterkisten für den Transport von Flüssigkeitsbehältern zu beseitigen, auch die verbliebenen kleineren Schwierigkeiten, wie sie sich noch für die oben genannte, schon sehr verbesserte Entwicklung herausgestellt haben, zu lösen, und eine Gitterkiste mit höchst verschleißfreiem Verschließsystem bzw. ein derartiges Verschließsystem als solches zur Verfügung zu stellen.The object of the invention is to eliminate the disadvantages of the conventional closing systems for lattice boxes for the transport of liquid containers, as well as to solve the remaining minor difficulties, such as have been found for the above-mentioned, already very improved development, and one Lattice box with extremely wear-free To provide a locking system or such a locking system as such.

Erfindungsgemäß wird dies für eine Gitterkiste der eingangs genannten Art dadurch erreicht, daß die Verschlußstange und die Halteelemente aus einem sehr widerstandsfähigen, unelastischen Kunststoffmaterial, insbesondere aus hartem, schlagfestem Kunstharz, in einer verformungswiderstrebenden, steifen Bauart gefertigt unbiegsam sind, und daß zwei spiegelbildlich zueinander gestaltete Halteelemente dazu vorgesehen sind, daß jedes einerseits ein Ende der Verschlußstange in sich aufnimmt und andererseits einen der die Ladeöffnung der Gitterkiste begrenzenden Längsstäbe hakenartig so hintergreift und an drei Seiten umschließt, daß die an der Kiste angeordnete Verschließeinrichtung in ihrem Zusammenhalt an diesen Längs- oder Eckstäben vertikal verschiebbar ist.According to the invention, this is achieved for a lattice box of the type mentioned at the outset in that the closure rod and the holding elements are made of a very resistant, inelastic plastic material, in particular made of hard, impact-resistant synthetic resin, are inflexible in a deformation-resistant, rigid construction, and that two mirror images of each other Retaining elements are provided so that each one receives one end of the locking rod and, on the other hand, engages behind one of the longitudinal bars delimiting the loading opening of the lattice box in a hook-like manner and encloses it on three sides in such a way that the closing device arranged on the box holds together on these longitudinal or corner bars is vertically displaceable.

Die Erfindung weist dadurch große Vorteile auf, daß nicht nur für die aus den zwei gleitenden Halteelementen und der Verschlußstange zusammengesetzte Verschließeinrichtung sondern vorzugsweise auch für die Gitterkiste selbst auf jegliches metallisches Baumaterial verzichtet und nur Kunststoffmaterial verwendet wird. Die Auswahl nur von Kunststoffmaterial ist das Ergebnis vieler Versuche, bei denen sich eine praktische Nichtverformbarkeit und eine sehr hohe Biegefestigkeit für die Kunststoffbauteile sowohl der Verschließeinrichtung als auch der Gitterkiste herausgestellt haben. Die zu verwendenden Kunststoffe haben eine sehr hohe Festigkeit, gewähren eine hohe Formstabilität der aus Ihnen gefertigten Teile, erleiden keine Qualitätsverluste durch Umwelteinflüsse und sind sehr leicht.The invention has great advantages in that not only for the closing device composed of the two sliding holding elements and the locking rod, but preferably also for the lattice box itself, no metallic building material is used and only plastic material is used. The selection of only plastic material is the result of many tests, in which a practical non-deformability and a very high bending strength for the plastic components of both the closing device and the crate have been found. The plastics to be used have a very high strength, ensure a high dimensional stability of the parts made from them, do not suffer any loss of quality due to environmental influences and are very light.

Erfindungsgemäß ist die Verschlußstange als gleichförmiger Kunststoff-, insbesondere Kunstharzprofilkörper ausgebildet, der einerseits aufgrund seines Kunststoffmaterials und andererseits aufgrund seiner Querschnittsform bei mechanischer Belastung einen besonders hohen Verformungswiderstand entgegensetzt. Vorzugsweise hat die Verschlußstange eine T-Profilform, wobei im Anordnungszustand der Verschlußstange an der Gitterkiste der T-Querbalken parallel zur Ebene der Ladeöffnung der Kiste steht. Wenngleich die genannte T-Form bevorzugt ist, sind auch andere schwer deformierbare Profile für die Verschlußstange möglich.According to the invention, the locking rod is designed as a uniform plastic, in particular synthetic resin profile body, which on the one hand due to its plastic material and on the other hand due to its cross-sectional shape mechanical stress opposes a particularly high resistance to deformation. The locking bar preferably has a T-profile shape, the locking bar on the grid box of the T-crossbar being parallel to the plane of the loading opening of the box when the locking bar is in the arrangement state. Although the T-shape mentioned is preferred, other profiles which are difficult to deform are also possible for the locking rod.

Die nachfolgend verwendeten Richtungsangaben beziehen sich auf den Anordnungszustand der erfindungsgemäßen Verschließeinrichtung an der Gitterkiste und auf einen vor der Verschließeinrichtung befindlichen Betrachter.The directional information used below relates to the state of arrangement of the closing device according to the invention on the grid box and to an observer in front of the closing device.

Die Halteelemente für die Verschlußstange sind vorzugsweise als Gußteile ausgeführt und gliedern sich in zwei funktionelle Teile, nämlich einen Hauptteil zur Aufnahme der Verschlußstange und einen kleineren Teil zur Anordnung des Halteelements an einem der die Ladeöffnung der Gitterkiste seitlich begrenzenden Längsstäbe.The holding elements for the locking rod are preferably designed as castings and are divided into two functional parts, namely a main part for receiving the locking rod and a smaller part for arranging the holding element on one of the longitudinal bars delimiting the loading opening of the lattice box.

Der Hauptteil des Halteelements weist an seiner zur Ebene der Ladeöffnung rechtwinklig stehenden, senkrechten Innenseite eine an die Querschnittsform der aufzunehmenden Verschlußstange angepaßte Aufnahmeöffnung für die Verschlußstange auf und trägt einen an der Seite der Aufnahmeöffnung beginnenden, L-förmig nach hinten außen wegspringenden Teil als den kleineren Teil des Halteelements. Der L-förmige Teil bildet mit der Hinterseite des Hauptteils des Halteelements einen sich nach außen öffnenden U-Haken aus, so daß die Aufnahmeöffnung des Halteelements für die Einordnung der Verschlußstange und die seitlich offene Seite des ausgebildeten U-Hakens voneinander wegzeigen.The main part of the holding element has on its vertical inside, which is perpendicular to the level of the loading opening, a receiving opening for the locking rod which is adapted to the cross-sectional shape of the locking rod to be accommodated and carries a part which starts at the side of the receiving opening and protrudes outward in an L-shaped manner as the smaller one Part of the holding element. The L-shaped part forms with the rear of the main part of the holding element an outwardly opening U-hook, so that the receiving opening of the holding element for the arrangement of the locking rod and the laterally open side of the formed U-hook point away from one another.

Zwei spiegelbildlich zueinander gestaltete Halteelemente der beschriebenen Art, von denen jedes auf ein Ende der Verschlußstange gesteckt ist, bilden die Verschließeinrichtung gemäß der Erfindung. Die Verschließeinrichtung ist in der Weise an der Gitterkiste angeordnet oder anzuordnen, daß dasjenige Halteelement, dessen U-Haken sich nach rechts öffnet, den die Ladeöffnung rechts begrenzenden Längsstab zwischen sich aufnimmt und das linke Halteelement entsprechend den linken Längsstab. Die an den Längsstäben angelegten Halteelemente sind hinsichtlich der Querschnittsform des U-Hakens so an den Querschnitt des Längsstabes angepaßt, daß sich ein ausreichendes Spiel für ein vertikales Verschieben der Verschließeinrichtung entlang dieser Längsstäbe einstellt, aber kein so großes Spiel, daß sich die Verschließeinrichtung von den Längsstäben lösen könnte.Two holding elements of the type described, designed in mirror image to one another, each of which is plugged onto one end of the locking rod, form the Closing device according to the invention. The closing device is arranged or arranged on the lattice box in such a way that the holding element, the U-hook of which opens to the right, receives the longitudinal bar delimiting the loading opening on the right and the left holding element correspondingly the left longitudinal bar. The holding elements applied to the longitudinal bars are adapted to the cross-section of the longitudinal bar with respect to the cross-sectional shape of the U-hook in such a way that there is sufficient play for vertical displacement of the closing device along these longitudinal bars, but not so much play that the closing device differs from the Longitudinal rods could loosen.

Sind, vorzugsweise, die die Verschließeinrichtung tragenden Längsstäbe der Gitterkiste als rechteckige Kantstäbe ausgebildet, weist der Querschnitt des U-Hakens des Halteelements ebenfalls einen rechteckigen Querschnitt auf. Bei abweichenden Querschnittsformen der Längsstäbe sind die Halteelemente entsprechend angepaßt auszugestalten.If, preferably, the longitudinal bars of the lattice box carrying the closing device are designed as rectangular square bars, the cross section of the U-hook of the holding element also has a rectangular cross section. In the case of deviating cross-sectional shapes of the longitudinal bars, the holding elements are to be designed accordingly.

Für die Anordnung der Verschließeinrichtung an der Gitterkiste bestehen mehrere Möglichkeiten.There are several options for arranging the closing device on the grid box.

Bei (noch) freistehenden Längsstäben läßt sich die zusammengesetzte Verschließeinrichtung auf diese Stäbe aufsetzen und dann an ihnen entlangführen, möglich etwa bei zerlegbaren Gitterkisten oder vor dem endgültigen Zusammenbau der Gitterkiste.In the case of (still) free-standing longitudinal bars, the assembled closing device can be placed on these bars and then guided along them, possible, for example, in the case of disassembled lattice boxes or before the lattice box is finally assembled.

Von dieser Technik kann für das nachträgliche Anordnen der Verschlußeinrichtung an einer nicht zerlegbaren Gitterkiste aber kein Gebrauch gemacht werden. Für einen solchen Fall kann dann wenigstens eines der Halteelemente eine durchgehende Öffnung für die Aufnahme des Verschlußstabes aufweisen und die Montage der Verschließeinrichtung an der Gitterkiste in der Weise erfolgen, daß man die Verschlußstange durch das Halteelement mit dem durchgehenden Aufnahmekanal etwas hindurchschiebt, dieses und das andere Halteelement am jeweiligen Längsstab anlegt und dann die Verschlußstange in das andere Halteelement hineinschiebt. Bei dieser Lösung muß dann vorgesehen sein, daß sich entweder die außen gelegene Öffnung des Halteelements, das den durchgehenden Kanal aufweist, für eine Unverrückbarkeit der Haltestange im Halteelement schließen, beispielsweise mit einem Stopfen oder Deckel abschließen, läßt, oder daß man das Ende der Verschlußstange in dem durchgehenden Kanal fixiert, beispielsweise mittels eines das Halteelement und die Haltestange durchdringenden, lösbaren Steck- oder Schraubbolzens.However, no use can be made of this technique for the subsequent arrangement of the closure device on a grid box which cannot be dismantled. In such a case, at least one of the holding elements can then have a continuous opening for receiving the locking rod and the locking device can be mounted on the lattice box in such a way that the locking rod is passed through the holding element with the continuous Slides through the receiving channel somewhat, puts this and the other holding element on the respective longitudinal rod and then pushes the locking rod into the other holding element. In this solution, it must then be provided that either the outer opening of the holding element, which has the through channel, can be closed for immovability of the holding rod in the holding element, for example closed with a plug or lid, or that the end of the locking rod can be closed fixed in the continuous channel, for example by means of a detachable plug or screw bolt penetrating the holding element and the holding rod.

Eine aus statischen Gründen aber zu bevorzugende Lösung zur Anordnung einer Verschließeinrichtung gemäß der Erfindung an einer nicht zerlegbaren Gitterkiste besteht darin, nur Halteelemente mit einem nicht durchgehenden Kanal zur Aufnahme der Verschlußstange zu verwenden und wenigstens eines der Halteelemente am Ende der Aufnahmehöhlung für die Verschlußstange mit einer elastischen oder federnden Einrichtung auszurüsten, die unter Kraftanwendung zuläßt, die Verschlußstange gegen die elastisch oder federnd nachgebende Einrichtung um eine solche Strecke zu verschieben, die größer ist als die Einstecktiefe der Verschlußstange in dem anderen Halteelement. Derartige Einrichtungen, beispielsweise eine am Ende des Aufnahmekanals längs angeordnete Spiralfeder, sind zur Vermeidung eines Spiels oder einer gewissen Freigängigkeit der Verschlußstange in den Halteelementen der zusammengebauten Verschließeinrichtung bei jeder der oben genannten weiteren Möglichkeiten empfehlenswert.A solution for arranging a closing device according to the invention on a grid box that cannot be dismantled, for structural reasons, is to use only holding elements with a non-continuous channel for receiving the locking rod and at least one of the holding elements at the end of the receiving cavity for the locking rod with one Equip elastic or resilient device which, with the application of force, allows the locking rod to be displaced against the resilient or resilient device by a distance which is greater than the insertion depth of the locking rod in the other holding element. Devices of this type, for example a spiral spring arranged lengthwise at the end of the receiving channel, are recommended in order to avoid any play or a certain freedom of movement of the locking rod in the holding elements of the assembled locking device in each of the other possibilities mentioned above.

Wie oben schon erläutert, läßt sich die an der Gitterkiste angeordnete Verschließeinrichtung an den sie tragenden Längsstäben vertikal verschieben, wobei die Verschlußstange in einer Position in etwa halber Kistenhöhe die Ladeöffnung der Gitterkiste gegen ein Heraustreten des Kisteninhalts sperrt und in einer möglichst hohen Position die Ladeöffnung am größten werden läßt. Dazu soll die Verschlußstange in den entsprechenden Positionen festlegbar sein, wozu folgende Einrichtungen vorgesehen sein können.As already explained above, the closing device arranged on the lattice box can be moved vertically on the longitudinal bars carrying it, the locking bar in a position at approximately half the height of the box blocking the loading opening of the lattice box against the contents coming out and the loading opening in the highest possible position the largest. For this purpose, the locking rod should be fixable in the appropriate positions, for which purpose the following devices can be provided.

Zur Positionierung der Verschlußstange in halber Höhe dient ein an jedem der die Verschlußeinrichtung tragenden Längsstäbe ein vorstehendes Sperrteil, das den Gleitweg der Verschließeinrichtung nach unten begrenzt, beispielsweise ein Stift oder Noppen, an dem der untere Teil des Halteelements anschlägt und aufliegt.For positioning the locking rod at half height, a protruding locking part is used on each of the longitudinal rods carrying the locking device, which limits the sliding path of the locking device downwards, for example a pin or knob, on which the lower part of the holding element strikes and rests.

Zur Arretierung der Verschlußstange ohne gesonderte Manipulation in einer obersten Position ist vorzugsweise ein selbsttätiger Verschlußmechanismus derart vorgesehen, daß ein an der einen Komponente angeordnetes zusammendrückbares Teil in eine Ausnehmung der anderen Komponente reversibel einrückt oder einrastet. Dazu dient vorzugsweise eine elastische, kappenförmige Vorwölbung an einer der drei Seiten des Längsstabes, an denen der U-Hakenteil des Halteelements entlanggleitet, und eine entsprechende Ausnehmung an der zugeordneten Innenseite des Halteelements. Wird das Halteelement also nach oben geschoben, drückt die die Vorwölbung des Längsstabes berührende Oberkante des Halteelements die nachgiebige Vorwölbung zurück und zusammen, und die Zusammendrückung bleibt, bis die vorzugsweise kugelkappenförmige Ausnehmung des Halteelements die Höhe der Vorwölbung erreicht hat, wonach sich die Vorwölbung in die Ausnehmung hinein ganz oder teilweise entspannt und das Halteelement so lange festhält, bis es wieder nach unten in Richtung der Verschlußlage gezogen wird.To lock the locking rod without special manipulation in an uppermost position, an automatic locking mechanism is preferably provided such that a compressible part arranged on one component reversibly engages or engages in a recess in the other component. An elastic, cap-shaped protrusion on one of the three sides of the longitudinal bar, on which the U-hook part of the holding element slides, and a corresponding recess on the associated inside of the holding element preferably serve for this purpose. If the holding element is pushed upwards, the upper edge of the holding element touching the protrusion of the longitudinal rod presses the resilient protrusion back and together, and the compression remains until the preferably spherical cap-shaped recess of the holding element has reached the height of the protrusion, after which the protrusion moves into the The recess is completely or partially relaxed and holds the holding element until it is pulled back down towards the closed position.

Wie die Fig. 1 bis 3 am deutlichsten zeigen, gliedert sich ein Halteelement 1 bzw. ein dazu spiegelbildliches Halteelement 1' in zwei funktionelle Teile, nämlich in einen mit einer Aufnahmeöffnung 3 versehenen Hauptteil zur Aufnahme einer Verschlußstange 5 und in einen zur Anordnung an einem Seitentstab 6 der Transportgitterkiste 8 vorgesehenen L-förmigen Teil 2. Der Hauptteil hat im wesentlichen die Form eines Quaders.As shown in FIGS. 1 to 3 most clearly, a holding element 1 or a holding element 1 'which is mirror-image thereto is divided into two functional parts, namely into a main part provided with a receiving opening 3 for receiving a locking rod 5 and one for arrangement on one Side bar 6 of the transport lattice box 8 provided L-shaped part 2. The main part has essentially the shape of a cuboid.

Zur Erzielung einer möglichst starren, verformungssteifen Bauart ist der für die Aufnahme der Verschlußstange vorgesehene Hauptteil des Halteelements 1 kantig ausgeführt, wobei seine Aufnahmeöffnung 3 vorzugsweise die Form eines T hat, dessen Fuß horizontal gegen die Entladeöffnung 12 und somit gegen die in der Kiste 8 eingeordneten Behälter (nicht dargestellt) weist. Dementsprechend hat die Verschlußstange 5 ein übereinstimmendes Profil. Die gezeigte T-Anordnung führt zu einem vorne flächigen Abschluß der angeordneten Verschlußstange 5 (vgl. Fig. 4).In order to achieve a construction that is as rigid as possible and resistant to deformation, the main part of the holding element 1 intended for receiving the locking rod is angular, its receiving opening 3 preferably having the shape of a T, the foot of which horizontally against the discharge opening 12 and thus against the ones arranged in the box 8 Containers (not shown) has. Accordingly, the locking rod 5 has a matching profile. The T-arrangement shown leads to a flat closure at the front of the arranged locking rod 5 (cf. FIG. 4).

Statt einer T-Form der Verschlußstange 5 und der Aufnahmeöffnung 3 sind auch andere geometrische, einer Biegung bzw. Verbiegung der Verschlußstange 5 widerstrebende Profilquerschnitte möglich.Instead of a T-shape of the locking rod 5 and the receiving opening 3, there are also other geometrical ones Bending or bending of the locking rod 5 resistive profile cross sections possible.

Der für die Anordnung am Seitenstab 6 vorgesehene Teil 2 des Halteelements 1 hat eine L-Form, die in Verbindung mit der Hinterseite des Hauptkörpers des Halteelements 1 eine U-förmige Aussparung 4 oder einen U-Haken ausbildet, dessen seitlich offene Seite in die Gegenrichtung der Aufnahmeöffnung 3 für die Verschlußstange 5 zeigt. Entsprechend, jedoch spiegelbildlich dazu, ist das Halteelement 1' ausgebildet.The part 2 of the holding element 1 provided for the arrangement on the side bar 6 has an L-shape which, in conjunction with the rear of the main body of the holding element 1, forms a U-shaped recess 4 or a U-hook, the side of which is open in the opposite direction the receiving opening 3 for the locking rod 5 shows. Correspondingly, but in mirror image, the holding element 1 'is designed.

Zur weiteren Versteifung des Halteelements 1 bzw. 1' kann an dessen Vorderseite eine Ausnehmung 11, die versteifende, sich nach unten verjüngende trapezförmige Seitenwände ausbildet bzw. durch solche Seitenwände gebildet ist, ebenso vorgesehen sein, wie eine im oberen hinteren Bereich des Halteelements 1 bzw. 1' gelegene, der T-Konfiguration der Aufnahmeöffnung 3 folgende Aussparung 13. Die Aussparungen 11 und 13 dienen zugleich der Material- und Gewichtseinsparung.For further stiffening of the holding element 1 or 1 ', a recess 11, which forms stiffening, tapering downward trapezoidal side walls or is formed by such side walls, can also be provided on the front side, such as one in the upper rear region of the holding element 1 or 1 'located recess 13 following the T configuration of the receiving opening 3. The recesses 11 and 13 also serve to save material and weight.

Die in den Fig. 1 bis 4 ferner zu erkennende, gegenüber der Höhe des Hauptteils des Halteelements 1 (nicht notwendigerweise) geringere Höhe des den U-Haken 4 ausbildenden L-förmigen Teils 2 des Halteelements 1 dient gleichfalls der Materialeinsparung und bewirkt andererseits bei der an der Gitterkiste 8 angeordneten Verschließeinrichtung 1,5,1' eine gewisse mögliche Klemmwirkung am Seitenstab 6 folgendermaßen.1 to 4, which can also be seen in relation to the height of the main part of the holding element 1 (not necessarily) the lower height of the L-shaped part 2 of the holding element 1 forming the U-hook 4 also serves to save material and, on the other hand, results in a certain possible clamping effect on the side bar 6 arranged on the grid box 8 closing device 1,5,1 'as follows.

Da der den Längsstab 6 hakenartig umgreifende Teil 2 des Halteelements 1 nur unterhalb der Verschlußstange 5 anliegt, stellt sich bei einer schräg nach außen oder innen gerichteten Krafteinwirkung auf die Verschlußstange 5 eine gewisse Schrägstellung des U-Hakens 4 gegenüber dem Längsstab 6 ein, die zu einer Einklemmung der Verschlußstange 5 am Halteelement 1 bzw. 1' führt.Since the part 2 of the holding element 1 which engages around the longitudinal rod 6 in a hook-like manner rests only below the locking rod 5, a certain inclined position of the U-hook 4 relative to the longitudinal rod 6 arises when the force acting on the locking rod 5 obliquely outwards or inwards, which too a jamming of the locking rod 5 on the holding element 1 or 1 'leads.

Demzufolge wird sich zumindest die leere Gitterkiste 8 auch an der Verschlußstange 5 anheben lassen, und zwar bei der jeweiligen Höhenposition, die die Verschließeinrichtung und damit die Verschlußstange 6 an der Gitterkiste 8 gerade einnimmt.As a result, at least the empty lattice box 8 can also be lifted on the locking bar 5, specifically at the respective height position which the locking device and thus the locking bar 6 on the lattice box 8 is currently occupying.

Die Höhenposition der Verschließeinrichtung 1,5,1' wird nach unten durch je einen Anschlag 7 begrenzt, der von einer der drei von dem Halteelement 1 umschlossenen Seiten des Längsstabes 6, vorzugsweise an dessen Vorderseite, hervorsteht, und auf denen die Halteelemente 1 und 1' in der Verschließposition der Verschlußstange 5 aufliegen. Die Anordnungshöhe der Anschläge 7 ist vorzugsweise so gewählt, daß die Verschlußstange 5 die Ladeöffnung 12 der Gitterkiste 8 gerade in deren Mitte unterteilt.The height position of the closing device 1, 5, 1 ′ is limited at the bottom by a stop 7, which protrudes from one of the three sides of the longitudinal bar 6, preferably on the front side thereof, and on which the holding elements 1 and 1 'rest in the closed position of the locking rod 5. The arrangement height of the stops 7 is preferably chosen so that the locking rod 5 divides the loading opening 12 of the crate 8 just in the middle.

Zur Erweiterung der Ladeöffnung 12 bis zu ihrer völligen Zugänglichkeit wird die Verschließeinrichtung 1,5,1' nach oben geschoben. Mittels einer an jedem Längsstab 6 oben angeordneten Vorwölbung 9, die sich von dem nach oben geschobenen Halteelement 1 bzw. 1' elastisch, gegebenenfalls auch federnd so zudrücken läßt, daß das Halteelement über sie hinweggleiten kann, und die dann in eine Ausnehmung 10 am U-hakenförmigen Teil des Halteelements 1 bzw. 1' vortritt, läßt sich die Verschließeinheit in einer obersten Position solange arretieren, bis sie wieder nach unten gezogen wird. Gemäß des Ausführungsbeispiels nach Fig. 3 und 4 befindet sich die Vorwölbung 9 an der der Ladeöffnung 12 zugekehrten Innenseite des Längsstabes 6 der Gitterkiste 8, und die daran angepaßte Aussparung 10 des Halteelements 1 ist an der Innenseite desjenigen Schenkels des L-förmigen Teils 2, welcher der Hinterseite des Hauptkörpers des Halteelements 1 gegenüberliegt, eingelassen (Fig. 3).To expand the loading opening 12 until it is completely accessible, the closing device 1,5, 1 'is pushed upwards. By means of a protrusion 9 arranged at the top of each longitudinal rod 6, which can be pressed elastically, if necessary also resiliently, by the holding element 1 or 1 'pushed upwards in such a way that the holding element can slide over it, and then into a recess 10 at the bottom -hooked part of the holding element 1 or 1 'occurs, the closing unit can be locked in an uppermost position until it is pulled down again. According to the exemplary embodiment according to FIGS. 3 and 4, the bulge 9 is located on the inside of the longitudinal bar 6 of the lattice box 8 facing the loading opening 12, and the recess 10 of the holding element 1 which is adapted to it is on the inside of that leg of the L-shaped part 2, which is opposite the rear of the main body of the holding element 1, embedded (Fig. 3).

Wie Fig. 4 zeigt, kann eine Gitterkiste 8 gemäß der Erfindung auch mit zwei sich gegenüberliegenden Ladeöffnungen 12 und demgemäß mit zwei Verschließeinrichtungen 1,5,1' gemäß der Erfindung ausgerüstet sein.As shown in FIG. 4, a lattice box 8 according to the invention can also have two opposing loading openings 12 and accordingly two Closing devices 1,5,1 'to be equipped according to the invention.

Die Anordnung der Verschließeinrichtung 1,5,1' an den dafür vorgesehenen Längsstäben 6 der Gitterkiste 8 kann bei zusammengebauter Verschließeinrichtung, wenn also die beiden spiegelbildlichen Halteelemente 1 und 1' in ihren Aufnahmehöhlungen 3 die Verschlußßstange 5 aufgenommen haben, in der Weise erfolgen, daß die Halteelemente über ein freiliegendes Ende der entsprechenden beiden Längsstäbe 6 eingesetzt werden. Läßt die Machart der Gitterkiste 8 ein derartiges Einsetzen nicht zu, ist der Zusammenbau der Verschließeinrichtung an der fertigen Gitterkiste 8 vorzunehmen. Dies erfordert eine horizontale Verschiebbarkeit der Verschlußstange 5 in wenigstens einem der Halteelemente 1 und 1'. Eine bevorzugte Möglichkeit, für eine Verschiebbarkeit der Verschlußstange 5 im Halteelement 1 und/oder 1' zu sorgen, beruht darauf, das in den Fig. 1 und 2 gezeigte Halteelement 1 am Ende der Öffnung oder Höhlung 3 mit einer Einrichtung zu versehen, die sich unter Kraftanwendung so zusammendrücken läßt, daß der Verschiebeweg der Stange 5 in der Öffnung 3 gegen deren Ende hin wenigstens so groß ist wie die vorgesehene Eindringtiefe der Verschlußstange 5 im gegenüberliegenden Halteelement. Die Anordnung der Verschließeinrichtung erfolgt dann beispielsweise so, daß zum Beispiel das Halteelement 1' und das Halteelement 1, welches die Verschlußstange 5 bereits aufgenommen hat am jeweiligen Längsstab 6 angelegt werden und dann die Verschlußstange 5 in das Halteelement 1 hineingedrückt wird, bis sich das freie Ende der Verschlußstange 5 vor der Öffnung 3 des Halteelements 1' befindet, und daß man dann die im Halteelement 1 zusammengedrückte Einrichtung sich entspannen und die Verschlußstange 5 in die Öffnung 3 des Halteelements 1' eindringen läßt. Die genannte zusammendrückbare Einrichtung kann beispielsweise eine Schraubenfeder sein.The arrangement of the closing device 1, 5, 1 'on the provided longitudinal bars 6 of the lattice box 8 can take place with the closing device assembled, that is to say when the two mirror-image holding elements 1 and 1' have received the closing rod 5 in their receiving cavities 3, in such a way that the holding elements are inserted over an exposed end of the corresponding two longitudinal bars 6. If the design of the mesh box 8 does not permit such an insertion, the closing device must be assembled on the finished mesh box 8. This requires a horizontal displacement of the locking rod 5 in at least one of the holding elements 1 and 1 '. A preferred way of ensuring a displaceability of the locking rod 5 in the holding element 1 and / or 1 'is based on providing the holding element 1 shown in FIGS. 1 and 2 at the end of the opening or cavity 3 with a device which can compressive force can be so that the displacement of the rod 5 in the opening 3 towards the end is at least as large as the intended depth of penetration of the locking rod 5 in the opposite holding element. The arrangement of the closing device is then carried out, for example, so that, for example, the holding element 1 'and the holding element 1, which the locking rod 5 has already received, are placed on the respective longitudinal rod 6 and then the locking rod 5 is pressed into the holding element 1 until the free one End of the locking rod 5 is in front of the opening 3 of the holding element 1 ', and that then the device compressed in the holding element 1 can relax and the locking rod 5 can penetrate into the opening 3 of the holding element 1'. The said compressible device can be, for example, a coil spring.

Eine andersartige Möglichkeit, für eine Verschiebbarkeit der der Verschlußstange 5 im Halteelement 1 und/oder 1' zu sorgen, liegt darin, das Halteelement mit einem (nicht gezeigten) durchgehenden, beiderseits offenen Aufnahmekanal 3 zu versehen. Ist beispielsweise die Aufnahmeöffnung 3 des Halteelements 1 an beiden Seiten offen, läßt sich die Anordnung der Verschließeinrichtung 1,5,1' etwa folgendermaßen vornehmen. Das Halteelement 1 wird auf die Verschlußstange 5 aufgesetzt und zur Mitte hin geschoben, worauf das Halteelement 1', das die Verschlußstange 5 bereits eingeordnet enthält, an seinem Längsstab 6 angelegt wird, wonach das Halteelement 1 an der Verschlußstange 5 zurückgeschoben wird, bis es an seinem Längsstab 6 anschlägt. Anschließend ist dafür zu sorgen, daß die Verschlußstange 5 und das Halteelement 1 in ihrer Zuordnung zueinander fixiert bleiben, was beispielsweise durch eine die Wandung des Kanals 3 und das Ende der Verschlußstange 5 durchdringendes Verbindungsteil (nicht gezeigt) bewerkstelligt werden kann. Andererseits ist es möglich, die am Ende der Verschlußstange 5 gelegene Öffnung des Kanals 3 gegen ein Heraustreten der Stange 5 abzuschließen, beispielsweise mit einem in geeigneter Weise festzumachenden Stopfen oder Deckel (nicht gezeigt).Another way of ensuring that the locking rod 5 can be displaced in the holding element 1 and / or 1 'is to provide the holding element with a continuous receiving channel 3 (not shown) which is open on both sides. If, for example, the receiving opening 3 of the holding element 1 is open on both sides, the arrangement of the closing device 1, 5, 1 'can be carried out approximately as follows. The holding element 1 is placed on the locking rod 5 and pushed towards the center, whereupon the holding element 1 ', which already contains the locking rod 5, is placed on its longitudinal rod 6, after which the holding element 1 is pushed back on the locking rod 5 until it is on strikes its longitudinal rod 6. It is then to be ensured that the locking rod 5 and the holding element 1 remain fixed in their assignment to one another, which can be accomplished, for example, by a connecting part (not shown) penetrating the wall of the channel 3 and the end of the locking rod 5. On the other hand, it is possible to close the opening of the channel 3 located at the end of the sealing rod 5 against the rod 5 coming out, for example with a stopper or cover (not shown) which can be fixed in a suitable manner.

Wie anfangs schon gesagt, ist außer der sich aus den zwei spiegelbildlichen Halteelementen 1 und 1' und der Verschlußstange 5 zusammensetzenden, nur aus deformations- und und verschleißfestem Kunststoffmaterial hergestellten Verschließeinrichtung vorzugsweise auch die eigentliche Gitterkiste 8 selbst aus einem ebensolchen Kunststoffmaterial und ohne Verwendung metallischer Materialien hergestellt.As already mentioned at the beginning, in addition to the closure device, which is composed of the two mirror-image holding elements 1 and 1 'and the locking rod 5 and is only made from deformation and wear-resistant plastic material, the actual lattice box 8 itself is preferably made of the same plastic material and without the use of metallic materials produced.
