Description

Vorrichtung zur lösbaren Verbindung einer Krankentrage auf einem KrankentragenfahrgestellDevice for the detachable connection of a stretcher on a stretcher trolley
Die Erfindung betrifft eine Vorrichtung zur lösbaren Verbindung einer Krankentrage auf einem Krankentragenfahrgestell mit zumindest einem, vorzugsweise zwei am Krankentragenfahrgestell angeordneten Verbindungselementen und mit in zumindest entsprechender Anzahl an der Krankentrage angeordneten, mit den Verbindungselementen am Krankentragenfahrgestell korrespondierend ausgebildeten Rastelementen.The invention relates to a device for the detachable connection of a stretcher on a stretcher chassis with at least one, preferably two connecting elements arranged on the stretcher chassis and with at least a corresponding number arranged on the stretcher and correspondingly designed with the connecting elements on the stretcher chassis.
Beim Transport von Krankentragen in Krankentransportfahrzeugen ist es üblich, daß die Krankentragen zusammen mit einem Krankentragenfahrgestell in das Krankentransportfahrzeug eingeschoben und das Krankentragentransportgestell im Krankentransportfahrzeug verriegelt wird. Die Krankentrage ist in der Regel derart ausgebildet, daß sie formschlüssig im Krankentragenfahrgestell angeordnet ist. Diese Ausgestaltung hat sich dahingehend als vorteilhaft erwiesen, daß die Krankentrage am Einsatzort schnell und einfach aus dem Krankentragenfahrgestell herausgehoben werden kann, um beispielsweise der Aufnahme des zu bergenden Unfallpatienten zu dienen. Nachdem der zu bergende Unfallpatient auf der Krankentrage gebettet ist, wird diese auf das Krankentragenfahrgestell aufgesetzt und das Krankentragenfahrgestell zusammen mit der Krankentrage in das Krankentransportfahrzeug eingeschoben, wobei das Krankentragenfahrgestell in der Regel aus einer ausgeklappten in eine eingeklappte Position überführt und mit dem Krankentransportfahrzeug bzw. in dem Krankentransportfahrzeug angeordneten Befestigungsvorrichtungen verriegelt wird.When transporting stretchers in ambulance vehicles, it is common for the stretchers to be inserted into the ambulance vehicle together with a stretcher chassis and for the ambulance transport frame to be locked in the ambulance vehicle. The stretcher is usually designed such that it is positively arranged in the stretcher trolley. This embodiment has proven to be advantageous in that the stretcher can be quickly and easily lifted out of the stretcher chassis at the place of use, for example to serve to accommodate the accident patient to be rescued. After the accident patient to be rescued is bedded on the stretcher, the stretcher is placed on the stretcher and the stretcher and the stretcher are pushed into the patient transport vehicle, whereby the stretcher usually moves from an unfolded position to a folded position and with the patient transport vehicle the ambulance arranged fastening devices is locked.
Bei diesem Stand der Technik ist es nachteilig, daß die Krankentrage nur auf das Krankentragenfahrgestell aufgelegt ist. Im Falle eines Unfalls des Krankentransportfahrzeuges oder auch bereits bei sehr schnell gefahrenen Kurven besteht die nicht unerhebliche Gefahr, daß sich die Krankentrage von dem Krankentragenfahrgestell löst und die im Patientenraum des Krankentransportfahrzeuges mitreisenden Personen, nämlich Notarzt und/oder Rettungspersonal erheblich verletzt. Diese Gefahr tritt insbesondere bei einem Unfall des Krankentransportfahrzeuges auf.In this prior art, it is disadvantageous that the stretcher is only placed on the stretcher chassis. In the event of an accident Ambulance vehicle or even when cornering very quickly there is a not inconsiderable risk that the stretcher will become detached from the stretcher chassis and seriously injure the people traveling in the patient compartment of the ambulance vehicle, namely the emergency doctor and / or rescue personnel. This danger occurs in particular in the event of an accident involving the patient transport vehicle.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung der gattungsgemäßen Art zu schaffen, die insbesondere bei Unfällen eine erhöhte Sicherheit in einem Krankentransportfahrzeug bereitstellt.Based on this prior art, the invention has for its object to provide a device of the generic type, which provides increased safety in an ambulance, particularly in the event of accidents.
Die L ö s u n g dieser Aufgabenstellung sieht vor, daß die Rastelemente in die Verbindungselemente automatisch und auf Druck selbsttätig einrastbar sind und daß die Verrastung zwischen den Rastelementen und den Verbindungselementen zum Lösen der Verrastung manipulierbar ist.The solution to this problem provides that the latching elements can be automatically latched into the connecting elements automatically and under pressure and that the latching between the latching elements and the connecting elements can be manipulated to release the latching.
Eine erfindungsgemäße Vorrichtung hat demzufolge den Vorteil, daß zwischen der Krankentrage und dem Krankentragenfahrgestell eine sichere Verbindung bereitgestellt wird, die eine automatische Verrastung ermöglicht. Die erfindungsgemäße Vorrichtung ermöglicht somit insbesondere in Verbindung mit einer Verrastung des Krankentragenfahrgestells im Krankentransportfahrzeug eine vollständige und sichere Verankerung des Patienten, so daß auch bei Unfällen des Krankentransportfahrzeuges eine unkontrollierte Bewegung der Krankentrage mit dem darauf auflastenden Patienten oder ausschließlich der Krankentrage vermieden wird. Durch die manipulierbare Verrastung kann die erfindungsgemäße Vorrichtung derart betätigt werden, daß die vorteilhaften Eigenschaften einer Kombination aus einer Krankentrage und einem Krankentragenfahrgestell am Unfailort erhalten bleiben, nämlich dahingehend, daß die Krankentrage sehr schnell vom Krankentragenfahrgestell gelöst werden kann. Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß jedes Verbindungselement als im Querschnitt im wesentlichen rechteckförmiges Profilelement ausgebildet ist, dessen Schmalseiten im wesentlichen rechtwinklig zu einer Seite mit einem einseitig offen ausgebildeten Schlitz zur Aufnahme des Rastelementes verlaufend angeordnet sind, wobei der Schlitz an seinem geschlossenen Ende ein Hakenelement aufweist, welches lösbar mit dem Rastelement verbindbar und um einen im wesentlichen parallel zur Flächennormalen der die Schmalseiten verbindenden Seite verlaufenden Achse verschwenkbar ist. Diese Ausgestaltung sieht somit vor, daß das Rastelement in einen Schlitz des Verbindungselementes einführbar ist. Am Ende des Schlitzes ist ein Hakenelement angeordnet, das von dem Rastelement derart betätigt wird, daß bei Auftreffen des Rastelementes auf das Hakenelement dieses Hakenelement das Rastelement im Verbindungselement sperrt. Über einen einfachen Seilzug kann das Hakenelement des Verbindungselementes gelöst werden, so daß nach Betätigung des Seilzuges oder einer anderen Auslöseeinrichtung das Rastelement aus dem Verbindungselement herausgezogen werden kann.A device according to the invention therefore has the advantage that a secure connection is provided between the stretcher and the stretcher chassis, which enables automatic locking. The device according to the invention thus enables a complete and secure anchoring of the patient, in particular in connection with a locking of the stretcher chassis in the patient transport vehicle, so that even in the event of accidents of the patient transport vehicle an uncontrolled movement of the patient carrier with the patient loading it or only the patient carrier is avoided. Due to the manipulable latching, the device according to the invention can be operated in such a way that the advantageous properties of a combination of a stretcher and a stretcher chassis are retained at the location of the accident, namely in that the stretcher can be detached from the stretcher chassis very quickly. According to a further feature of the invention, it is provided that each connecting element is designed as a profile element which is substantially rectangular in cross section, the narrow sides of which are arranged essentially at right angles to one side with a slot designed to be open on one side for receiving the latching element, the slot being closed at its closed end End has a hook element which is releasably connectable to the latching element and is pivotable about an axis running essentially parallel to the surface normal of the side connecting the narrow sides. This configuration thus provides that the latching element can be inserted into a slot in the connecting element. At the end of the slot there is a hook element which is actuated by the latching element in such a way that when the latching element hits the hook element, this hook element blocks the latching element in the connecting element. The hook element of the connecting element can be released by means of a simple cable pull, so that the latching element can be pulled out of the connecting element after actuation of the cable pull or another triggering device.
Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß der Schlitz zu seinem offenen Ende hin sich V-förmig erweiternd ausgebildet ist. Diese Ausgestaltung hat den Vorteil, daß das Einschieben des Verrastelementes in das Verbindungselement wesentlich vereinfacht wird und daß das Rastelement in dem sich V-förmig erweiternden Schlitz in die richtige Position am Ende des Schlitzes geführt wird.According to a further feature of the invention it is provided that the slot is designed to widen in a V-shape towards its open end. This configuration has the advantage that the insertion of the latching element into the connecting element is considerably simplified and that the latching element is guided into the correct position at the end of the slot in the V-shaped widening slot.
Eine Weiterbildung der erfindungsgemäßen Vorrichtung sieht vor, daß das Hakenelement als um die Achse verschwenkbare, federbelastete Sperrklinke ausgebildet ist, welche mit einem Auslöseelement verbunden ist. Diese Ausgestaltung dient insbesondere der vereinfachten Handhabung und der konstruktiven Vereinfachung der Vorrichtung. Hierbei ist es nach einem weiteren Merkmal der Erfindung vorgesehen, daß das Auslöseelement einen Griff aufweist, der nach außerhalb des Profilelementes vorsteht. Dieser Griff kann entweder direkt oder über ein Kraftübertragungselement, beispielsweise einen Bouwdenzug, ein Gestänge oder dergleichen betätigt werden.A further development of the device according to the invention provides that the hook element is designed as a spring-loaded pawl which can be pivoted about the axis and which is connected to a release element. This configuration serves in particular to simplify handling and to simplify the construction of the device. Here it is after one Another feature of the invention provided that the trigger element has a handle which protrudes outside the profile element. This handle can be actuated either directly or via a force transmission element, for example a bouwden cable, a linkage or the like.
Weiterhin ist vorgesehen, daß das Auslöseelement in Querrichtung des Profilelements verschiebbar ist, wobei das Auslöseelement vorzugsweise in einer Bohrung des Profilelements geführt ist.It is further provided that the release element is displaceable in the transverse direction of the profile element, the release element preferably being guided in a bore in the profile element.
Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß zwischen dem Auslöseelement und dem Profilelement eine vorgespannte Zugfeder angeordnet ist, die dafür Sorge trägt, daß das mit der Sperrklinke verbundene Auslöseelement die Sperrklinke automatisch in eine Sperrstellung verschiebt. Diese Sperrstellung verläßt die Sperrklinke nur in dem Moment, in dem das Rastelement auf eine in Richtung der Schlitzöffnung angeordnete, schräg verlaufende Fläche der Sperrklinke auftrifft und aufgrund der Schrägstellung der Fläche diese Sperrklinke aus der Sperrstellung herausgedrückt wird. Unmittelbar nachdem das Rastelement vollständig an der schrägstehenden Fläche der Sperrklinke vorbei geschoben ist, zieht die Zugfeder die Sperrklinke in ihre Sperrstellung, wobei die Kraft der Zugfeder auf das Auslöseelement übertragen wird, welches Auslöseelement formschlüssig mit der Sperrklinke verbunden ist.According to a further feature of the invention it is provided that a prestressed tension spring is arranged between the release element and the profile element, which ensures that the release element connected to the pawl automatically moves the pawl into a locking position. This locking position leaves the pawl only at the moment when the locking element strikes an inclined surface of the pawl arranged in the direction of the slot opening and this pawl is pressed out of the locking position due to the inclined position of the surface. Immediately after the locking element is pushed completely past the inclined surface of the pawl, the tension spring pulls the pawl into its locking position, the force of the tension spring being transmitted to the release element, which release element is positively connected to the pawl.
Die Rastelemente sind vorzugsweise an einem Gestell an der Unterseite der Krankentrage befestigt. Weiterhin ist vorgesehen, daß die Rastelement jeweils einen an der Krankentrage befestigbaren Grundkörper aufweisen. Die Rastelemente sind relativ zu den Grundkörpern verstellbar.The locking elements are preferably attached to a frame on the underside of the stretcher. Furthermore, it is provided that the locking element each have a base body that can be attached to the stretcher. The locking elements are adjustable relative to the base bodies.
Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß die Rastelemente aus einer Gewindestange oder einem Gewindestangenabschnitt und einer vorzugsweise runden Platte bestehen, die gegebenenfalls unter Zwischenanordnung eines Stabelementes an der Gewindestange oder dem Gewindestangenabschnitt befestigt ist, wobei die Außenabmessungen, insbesondere der Durchmesser der Platte größer ist als der Durchmesser des Stabelementes und/oder der Gewindestange bzw. des Gewindestangenabschnitts und der Breite des Schlitzes im Bereich des Hakenelementes.According to a further feature of the invention it is provided that the locking elements from a threaded rod or Threaded rod section and a preferably round plate, which is optionally attached to the threaded rod or the threaded rod section with the interposition of a rod element, the outer dimensions, in particular the diameter of the plate being larger than the diameter of the rod element and / or the threaded rod or the threaded rod section and the Width of the slot in the area of the hook element.
Vorzugsweise ist die Gewindestange bzw. der Gewindestangenabschnitt in eine Gewindebohrung im Grundkörper einschraubbar, so daß das Rastelement hinsichtlich einer präzisen Lage relativ zum Verbindungselement einstellbar ist.The threaded rod or the threaded rod section can preferably be screwed into a threaded bore in the base body, so that the latching element can be adjusted with respect to a precise position relative to the connecting element.
Um die erfindungsgemäße Vorrichtung nachträglich an bereits bestehende Krankentragen anzuordnen ist es vorteilhaft, daß der Grundkörper aus zwei miteinander verbindbaren, vorzugsweise verschraubbaren Hälften besteht, die ein Konstruktionselement der Krankentrage umgreifen.In order to retrofit the device according to the invention on already existing stretchers, it is advantageous that the base body consists of two halves which can be connected, preferably screwed together, and which encompass a structural element of the stretchers.
Schließlich hat es sich als vorteilhaft erwiesen, zwei Rastelemente und zwei Verbindungselemente jeweils diametral gegenüberliegend an derFinally, it has proven advantageous to have two latching elements and two connecting elements, each diametrically opposite one another on the
Krankentrage und dem Krankentragenfahrgestell anzuordnen, so daß eine sichere, auch bei Unfällen haltbare Verbindung zwischen der Krankentrage und dem Krankentragenfahrgestell erzielt wird.

These locking elements 7 are described in detail below.
Die Figur 2 zeigt ein Krankentragenfahrgestell 8 in Draufsicht. Das Krankentragenfahrgestell 8 besteht ebenfalls aus einem Rahmen 9, der zwei Längsträger 10 und mehrere die Längsträger 10 miteinander verbindende Querträger 11 aufweist.Figure 2 shows a stretcher chassis 8 in plan view. The stretcher chassis 8 also consists of a frame 9 which has two side members 10 and a plurality of cross members 11 connecting the side members 10 together.
An dem Rahmen 9 ist ein an sich bekanntes klappbares Fahrgestell 12 befestigt. Dieses Fahrgestell 12 kann in einer ausgeklappten Stellung arretiert werden. Für den Transport des Fahrgestells 12 mit der darauf angeordneten Krankentrage 1 in einem nicht dargestellten Krankentransportfahrzeug wird das Fahrgestell 12 aus seiner ausgeklappten Stellung in seine eingeklappte Stellung verschwenkt, wobei das Fahrgestell 12 dann im wesentlichen direkt an den Längsträgern 10 bzw. den Querträgern 11 des Rahmens 9 des Krankentragenfahrgestells 8 anliegt. Zum Lösen der das Fahrgestell in seiner ausgeklappten Stellung haltenden Arretierelemente sind an beiden Schmalseiten desA foldable chassis 12 known per se is attached to the frame 9. This chassis 12 can be locked in an extended position. For the transport of the chassis 12 with the stretcher 1 arranged thereon in a patient transport vehicle (not shown), the chassis 12 is pivoted from its unfolded position into its retracted position, the chassis 12 then essentially directly on the longitudinal members 10 or the cross members 11 of the frame 9 of the stretcher chassis 8 is present. To release the locking elements holding the chassis in its unfolded position are on both narrow sides of the
Krankentragenfahrgestells 8 Griffelemente 13 vorgesehen, die über ein Gestänge mit den Arretierelementen des Fahrgestells 12 verbunden sind.Stretcher chassis 8 handle elements 13 are provided which are connected to the locking elements of the chassis 12 via a linkage.
Das Krankentragenfahrgestell 8 weist zwischen den Längsträgern 10 eine Tragplatte 14 auf, die sich im wesentlichen über die gesamte Länge des Rahmens 9 des Krankentragenfahrgestells 8 erstreckt. Die Tragplatte 14 stützt sich auf den Querträgern 11 ab und ist mit diesen verschraubt oder vernietet.The stretcher chassis 8 has a support plate 14 between the longitudinal beams 10, which extends substantially over the entire length of the frame 9 of the stretcher chassis 8. The support plate 14 is supported on the cross members 11 and is screwed or riveted to them.
Zwischen der Tragplatte 14 und jeweils einem Längsträger 10 sind diametral gegenüberliegend zwei Platten 15 angeordnet, die einerseits an einem Längsträger 10 und andererseits an der Tragplatte 14 befestigt, das heißt verschraubt oder vernietet sind. Jede Platte 15 trägt ein nachfolgend noch beschriebenes Verbindungselement 16, welches zur lösbaren Verbindung mit einem Rastelement 7 der Krankentrage 1 vorgesehen ist, so daß die Krankentrage 1 formschlüssig mit dem Krankentragenfahrgestell 8 verbunden wird.Two plates 15 are arranged diametrically opposite each other between the support plate 14 and a longitudinal beam 10 Side member 10 and on the other hand attached to the support plate 14, that is screwed or riveted. Each plate 15 carries a connecting element 16, described below, which is provided for releasable connection to a latching element 7 of the stretcher 1, so that the stretcher 1 is positively connected to the stretcher chassis 8.
Eine Ausgestaltung des Verbindungselementes 16 ist in der Figur 6 dargestellt. Das Verbindungselement 16 besteht aus einem rechteckförmigen Profilelement 17, welches zwei parallel zueinander verlaufende Platten 18 und 19 aufweist, die beabstandet zueinander angeordnet und über Schmalseiten 20 miteinander verbunden sind. Das Profilelement 17 weist in seiner Platte 19 einen einseitig offen ausgebildeten Schlitz 21 auf, der sich zu seinem offenen Ende hin V-förmig erweitert.An embodiment of the connecting element 16 is shown in FIG. 6. The connecting element 16 consists of a rectangular profile element 17 which has two plates 18 and 19 running parallel to one another, which are arranged at a distance from one another and are connected to one another via narrow sides 20. The profile element 17 has in its plate 19 a slot 21 which is open on one side and widens in a V-shape towards its open end.
Der Schlitz 21 dient der Aufnahme des Rastelementes 7 und weist im Bereich seines geschlossenen Endes ein Hakenelement 22 auf, welches lösbar mit dem Rastelement 7 verbindbar ist, wobei in der Figur 6 lediglich ein zylinderförmiger Abschnitt 23 des Rastelementes 7 dargestellt ist. Das Hakenelement 22 ist mit einer Lasche 24 verbunden, die um eine Achse 25 am Profilelement 17 verschwenkbar ist. An seinem der Achse 25 gegenüberliegenden Ende ist die Lasche 24 an einem Auslöseelement 26 befestigt, welches Auslöseelement 26 als L-förmige Achse ausgebildet ist, die durch eine Schmalseite 20 des Profilelementes 17 greift und an ihrem aus dem Profilelement 17 hervorstehenden Ende einen Handgriff 27 hat.The slot 21 serves to receive the locking element 7 and has a hook element 22 in the area of its closed end, which can be detachably connected to the locking element 7, only a cylindrical section 23 of the locking element 7 being shown in FIG. The hook element 22 is connected to a tab 24 which is pivotable about an axis 25 on the profile element 17. At its end opposite the axis 25, the tab 24 is fastened to a trigger element 26, which trigger element 26 is designed as an L-shaped axis which engages through a narrow side 20 of the profile element 17 and has a handle 27 at its end protruding from the profile element 17 .
Das Auslöseelement 26 ist mittels des Handgriffs 27 in Richtung eines Pfeils 28 entgegen einer Federkraft einer Feder 29 verschiebbar im Profilelement 17 gelagert. Wird der Abschnitt 23 des Rastelementes 7 in den Schlitz 21 des Profilelementes 17 eingeschoben, so haftet das Rastelement 7 hinter dem Hakenelement des Profilelementes 17 ein. Ohne Betätigung des Auslöseelementes 26 kann das Rastelement 7 nicht mehr aus dem Verbindungselement 16 freigegeben werden. Erst eine Betätigung des Handgriffs 27 und die damit verbundene Bewegung des Hakenelementes 22 gibt das Rastelement 7, das heißt dessen Abschnitt 23 frei, so daß das Rastelement 7 aus dem Schlitz 21 herausgezogen werden kann. Die in Figur 2 dargestellte Ausführungsform des Verbindungselementes 16 unterscheidet sich von der in Figur 6 dargestellten Ausführungsform des Verbindungselementes 16 dadurch, daß das Auslöseelement 26 über einen Seilzug oder Bouwdenzug 30 mit einem Zuggriff 31 verbunden ist. Der Zuggriff 31 ist an einem Ende des Rahmens 9 des Krankentragenfahrgestells 8 angeordnet.The trigger element 26 is mounted by means of the handle 27 in the direction of an arrow 28 against a spring force of a spring 29 in the profile element 17. If the section 23 of the locking element 7 is inserted into the slot 21 of the profile element 17, the locking element 7 adheres behind the hook element of the profile element 17. Without actuation of the release element 26, the latching element 7 can no longer be released from the connecting element 16. Only when the handle 27 is actuated and the associated movement of the hook element 22 releases the locking element 7, that is to say its section 23, so that the locking element 7 can be pulled out of the slot 21. The embodiment of the connecting element 16 shown in FIG. 2 differs from the embodiment of the connecting element 16 shown in FIG. 6 in that the release element 26 is connected to a pull handle 31 by means of a cable or cable pull 30. The pull handle 31 is arranged at one end of the frame 9 of the stretcher chassis 8.
Es kann hierbei vorgesehen sein, daß beide Verbindungselemente 16 über einen gemeinsamen Zuggriff 31 manipulierbar, das heißt steuerbar sind, so daß beide Verbindungselemente 16 gleichzeitig entrastet werden können. Das in den Figuren 4 und 5 dargestellte Rastelement 7, welches an dem Rahmen 2 der Krankentrage 1 befestigbar ist, weist einen Grundkörper 32 auf, welcher im Ausführungsbeispiel aus einem im Querschnitt im wesentlichen U-förmigen Profilstück 33 mit seitlich angeordneten Flanschen 34 besteht, wobei die Flansche jeweils eine Bohrung 35 zur Aufnahme von nicht dargestellten Befestigungsschrauben haben. Die Flansche 34 sind an den freien Enden des U-förmigen Profilstücks 33 kolinear angeordnet. Zwischen den Flanschen 34 ist ferner ein klobenförmiges Element 36 am Grundkörper 32 befestigt, welches im Querschnitt im wesentlichen rechtwinklig und im Längsschnitt im wesentlichen trapezförmig ausgebildet ist. In diesem aus vollem Material bestehenden Element 36 ist eine Gewindebohrung 37 angeordnet, die rechtwinklig zur Längsachse des U- förmigen Profilstücks 33 verläuft. In diese Gewindebohrung 37 ist ein Gewindestangenabschnitt 38 eingeschraubt, der koaxial in den Abschnitt 23 übergeht, an dessen freien Ende ein Schraubenkopf 39 mit Schlitz 40 angeordnet ist. Der Durchmesser des Schraubenkopfes 39 ist größer als der Durchmesser des Abschnitts 23. Ferner ist der Durchmesser des Schraubenkopfes 39 größer als die lichte Weite des Schlitzes 21 im Anschluß an die V-förmige Erweiterung des freien Endes dieses Schlitzes 21.It can be provided here that both connecting elements 16 can be manipulated, that is to say controlled, via a common pull handle 31, so that both connecting elements 16 can be unlocked simultaneously. The locking element 7 shown in FIGS. 4 and 5, which can be fastened to the frame 2 of the stretcher 1, has a base body 32, which in the exemplary embodiment consists of a profile piece 33 with a cross section which is essentially U-shaped with flanges 34 arranged on the side, whereby the flanges each have a bore 35 for receiving fastening screws, not shown. The flanges 34 are arranged colinearly at the free ends of the U-shaped profile piece 33. Between the flanges 34, a block-shaped element 36 is also fastened to the base body 32, which is essentially rectangular in cross-section and essentially trapezoidal in longitudinal section. In this element 36, which is made of solid material, a threaded bore 37 is arranged, which runs at right angles to the longitudinal axis of the U-shaped profile piece 33. A threaded rod section 38 is screwed into this threaded bore 37, which coaxially merges into section 23, at the free end of which a screw head 39 with a slot 40 is arranged. The diameter of the screw head 39 is larger than the diameter of the section 23. Furthermore, the diameter of the screw head 39 is larger than the clear width of the slot 21 following the V-shaped expansion of the free end of this slot 21.
Es ist aus den Figuren 4 und 5 zu erkennen, daß auf dem Gewindestangenabschnitt 38 ein Konterelement 41 aufgeschraubt ist. Gewindestangenabschnitt 38, Element 23 und Schraubenkopf 39 können bei diesem Rastelement 7 relativ zum Grundelement 32 verstellt werden. Um den Gewindestangenabschnitt 38, das Element 23 und den Schraubenkopf 39 nach erfolgter Einstellung gegenüber dem Element 36 festzusetzen, ist das Konterelement 41 gegen das Element 36 zu verschrauben. Die Einstellbarkeit des Abschnitts 23 relativ zu dem Element 36 ist in der Figur 5 durch den Doppelpfeil 42 dargestellt. It can be seen from FIGS. 4 and 5 that a counter element 41 is screwed onto the threaded rod section 38. Threaded rod section 38, element 23 and screw head 39 can be adjusted relative to the base element 32 in this latching element 7. In order to fix the threaded rod section 38, the element 23 and the screw head 39 after the adjustment relative to the element 36, the counter element 41 must be screwed against the element 36. The adjustability of the section 23 relative to the element 36 is shown in FIG. 5 by the double arrow 42.
