Definitions
- the invention relates to a Tragstoffendinformation for fastening a support means of an elevator system and an elevator installation, in which the support means are fastened via a Tragstoffenditati.
- the suspension means for an elevator car must be securely fastened in the elevator shaft in order to transmit the forces which occur to a supporting structure which is arranged in the elevator shaft.
- the support means such as ropes or belts are fastened during assembly with their end pieces in the Tragstoffendverbinder. In general, this is a loop in the rope, or set the belt and the support means is clamped in Tragstoffendverbinder, for example, by a wedge, which exerts a contact pressure on the rope or the belt, so that this / this against the housing of Tragstoffendverbinders is pressed and can not exude.
- a Tragstoffendverbinder in which the support means is wrapped around two wrapping elements, for example, from WO 2008/148768 known.
- a wrapping element is fixed in the housing and the second wrapping element can be inserted through an opening in the housing in the loop.
- the second wrapping element in this case consists of a sleeve and a bolt to be inserted into the sleeve, wherein the bolt is fixed by means of a tensioned by a spring mechanism in the sleeve.
- the object of the present invention is to provide a Tragstoffendthetic in which the fixing of the second wrap element is improved.
- a Tragstoffendthetic for attachment of a suspension element of an elevator system comprising a housing comprising two side walls, with at least two substantially cylindrical Umschlingungs instituten for attachment of the support means, wherein the wrap each extending between the two side walls and wherein the second wrap element designed as a movable bolt can be inserted into the housing, with a attachable to the housing fixing element for fixing the second wrapping element in its position in the housing, characterized in that the fixing element is designed such that it is in at least one between the side walls of the housing coming to recess engages the second wrapping element.
- the invention is based on the finding that the fixing of a bolt introduced into the housing, which constitutes the second belt element, can be carried out particularly simply if this bolt has a recess into which a fixing element, which can be attached to the housing, engages.
- the bolt can then no longer be moved against the fixing element and thus also against the housing.
- the bolt is fixed in its position in the housing.
- the depression can in this case run in the longitudinal or in the transverse direction of the bolt.
- the fixing element remains stable in its position relative to the housing.
- the fixing element is designed such that it is firmly connected to the housing, in particular on a lower yoke of the housing. Any force caused by displacement of the bolt against the fixing element can thereby be transferred to the housing. By its attachment to the housing is the fixing element secured against forces transmitted by the bolt and can thus secure the position of the bolt in the housing.
- a further advantageous embodiment of the invention is characterized in that the fixing element has a substantially parallel to a side wall of the housing in the housing extending surface, wherein the surface has a complementary to the cross-sectional shape of the second wrap element indentation, and wherein the indentation sized is that it can accommodate the second wrap only at its at least one recess.
- the bolt can be received only at the point with its recess of the fixing element, so that it is ensured during assembly that the fixing element or the bolt is optimally seated in relation to the position of the fixing element. If the fixing element is fastened to the housing in such a way that the surface with its indentation does not engage directly in the recess of the bolt, then the bolt can not be received in the indentation and the fixing element can not penetrate deep enough into the housing with its surface, so that a fitter immediately noticed that the fixing element can not be properly positioned. Only when the indentation receives the bolt in itself, the fixing element is correctly attached to the housing and does not protrude beyond the side walls of the housing.
- a further advantageous embodiment of the invention is characterized in that extending into the housing surface of the fixing element is dimensioned such that the flanks of the recess extending beyond the center of the cross section of the second wrapper addition.
- a further advantageous embodiment of the invention is characterized in that the flank of the fixing element arranged between the lower yoke of the housing and the second looping element is dimensioned such that it substantially fills the space between the yoke and the looping element.
- a further advantageous embodiment of the invention is characterized in that a support means end piece laid to form a loop can be arranged in the housing in such a way that the two opposing regions of the loop wrap around the first wrapping element and the second wrapping element can be inserted through the eye of the loop.
- Fig. 1 shows by way of example a Tragstoffendtagen 6, which is provided for receiving a support means 2, and in which the support means 2 is fixed so that it is held by the Tragstoffendtagen 6.
- the Tragstoffendtagen 6 in this case has a housing 1, which has two side walls 11, 12. At the front, the housing is substantially open.
- the support means 2 is arranged in the housing 1 so that a movable and insertable into the housing wrap 4 comes to rest in the eye of a loop of the suspension element.
- the wrapping element has a recess 41.
- FIG. 2 is a TragstoffendENS shown, in which the wrapping element 4 is now inserted, and is wrapped by an eye of the support means.
- the support means 2 is now held by the frictional force between the surfaces of the support means in the Tragstoffendverbinder.
- the wrapping element 4 can be introduced through an opening 14 through a side wall 11, 12 of the housing 1.
- the wrapping element can now be fixed in its position in the housing and does not slip sideways or slip out of the housing, the fixing element 5 becomes on the lower yoke 13 of the housing attached.
- the fixing element can also be fixed at other locations of the housing, for example on the side wall 11 or 12 of the housing.
- An attachment to the lower yoke 13 is particularly easy to implement, since a surface of the fixing element can be screwed with a bore by means of a screw 55 in the yoke.
- a roller or a pin-shaped element 56 can be attached under the fixing element or between the fixing element and the support means 2.
- the pin-shaped element 56 may be made of metal or of another, non-combustible, in particular non-electrically conductive material. It is clamped when tightening the fixing element 5 between quasi fixing element and support means and thus exerts on the end of the support means pressure. This serves to additionally secure the suspension element 2 in the housing.
- load-bearing tension members melts away, not enough pressure is exerted on the tension members and the frictional force of the support means is no longer sufficient to hold it in Tragstoffendverbinder.
- the roll which is not combustible, is drawn into the gap 15 between the first yoke 13 and the second yoke 17 ( Fig. 5 ).
- the tension members thus experience a pressure and are clamped to the housing by the roller or the pin.
- the gap 15 narrows between the first yoke 13 and the second yoke 17 in the direction of the housing interior.
- the pin or the roller is formed of non-electrically conductive material. If the condition of the tension members is monitored by means of electrical continuity, it must be prevented that an electrical connection via the pin-shaped element is achieved by the pressing of the roller on the strands.
- FIG. 3 shows a Tragstoffend für 6 in a state in which no support means is inserted.
- the Tragstoffend für has a housing 1 with two side walls 11,12, wherein between the side walls, a first wrapping element 3 is attached.
- the second wrapping element 4 can be introduced into the housing 1 through an opening 14 in the side wall 11 or 12. This is usually done after a suspension has already run into the housing and then introduces the second wrap 4 and the bolt in the eye of the support means.
- a sketch of the arrangement is shown on the side surface 11. If the second wrapping element 4 is now inserted into the end connector 6, the recess 41 of the second wrapping element comes to lie within the housing, that is to say between the two side walls 11 and 12. It is advantageous if the depression is indeed within the housing but relatively far at the edge, so near one of the two side walls.
- FIG. 4 shows the fixing element 5, which for fixing the in FIG. 3 and 1 shown second wrap 4 serves.
- the fixing element can be fastened to the housing 1.
- a flat element 57 is proposed for this purpose, which has a bore through which it by means of a screw 55 on the lower yoke 13th the housing 1 of the Tragstoffendverbinders 6 can be attached.
- the attachment to the housing can also be done in other ways.
- the fixing element 5 has a surface 51 which extends parallel to a side wall 11, 12 of the housing in the mounted state.
- the illustrated embodiment is merely an example. The surface may extend on either side of the housing, respectively.
- the fixing element 5 would have two parallel surfaces extending along the side surfaces of the housing. Each of the two surfaces would then engage one of two recesses of the bolt or receive the bolt in one of two recesses.
- the surface 51 has a recess 52.
- the indentation is provided for receiving the belt 4.
- the indentation 52 is dimensioned such that the wrapping element 4 can only be accommodated in it when the walls of the indentation engage in the recess 41 of the wrapping element.
- flank 53, 54 of the recess are pulled down so far that they protrude beyond the center of the belt. This ensures that even if the fixing element 5 is not seated 100 percent, the surface 51 of the fixing element is able to hold the belt 4 in its position.
- the flank 53 is selected in its width so that when inserting the fixing element 5 into the housing 1 for the flank 53 there is just so much space between the yoke and the bolt or wrap element 4 wrapped around the suspension element 2 Fixing element can be placed there. A rotational movement of the entire fixing element, for example, if the surface 57 is no longer screwed tightly to the yoke 13, thus can not immediately lead to a solution of the bolt 4.
- flank would still be close enough to the bolt in the event that the fixing element 5 loosens a little and wobbles, and even intervene in the recess 41 during rotation.
- annular recess in the bolt ensures that the flank always engages.
- a circumferential groove has the further advantage that the bolt must be adjusted only with respect to the lateral alignment. Turning the bolt in the Housing to bring him into a position in which the fixing element can engage is not necessary.
- the small roller or pin 56 which can prevent noise emanating from the suspension element even in the event of a fire, is to be positioned between the fixing element 5 and the suspension element 2, this is shown graphically on the fixing element.
- the special design of the fixing element 5, as in FIG. 4 is merely an example.
- the fixing element can be fastened at arbitrary locations of the housing. It is relevant that it engages in the fastened state in a recess of the bolt 4 and thus protects it from lateral movement.
- a fixation on the side walls is conceivable or a fixing element with a completely different shape and two surfaces which each extend to a side wall of the housing and penetrate there into the depth and hold the wrapper in position.
- the indentation 52 need not be round, as shown, it conforms to the shape of the bolt, and if the bolt has a different shape, the indentation 52 would have a corresponding complementary shape.
- the fixing element could, of course, also be a simple element protruding in the depth, without indentation, which engages in a recess of the bolt 4.
- FIGS. 5, 6 and 7 show the insertion of the support means 2 in a Tragstoffenditati 6.
- the support means 2 is placed in a loop 20. This happens because the end of the support means is guided by a fitter through the opening 16 provided on the housing. Then the support means 2 is bent in the direction of the housing and out through the second opening 15, which is also located at the lower end of the housing between the yoke 13 and the yoke 17, out of the housing. Subsequently, the suspension element or the loop 20 can be placed over the first belt 4. This is in FIG. 6 shown. Around the wrap 4 thus lie two opposite areas of the suspension element. The end of the loop of the support means then forms an eye 23. In the eye 23, the bolt 3 and the second wrapping element can be inserted.
- the support means 2 then only needs to be brought to tension on the side remote from the end by train.
- the support means may in this case be a flat belt, the belt may also have a surface structure, as for example in Figures 1 and 2 is shown. Whether the surface structures of the suspension element lie on top of each other or whether the flat sides of a support belt lie on top of each other is not relevant for the function of the suspension element end connection.
- the strap can thus be introduced in both directions even if its surfaces are designed differently.

Abstract
Description
Die Erfindung betrifft eine Tragmittelendverbindung zur Befestigung eines Tragmittels einer Aufzugsanlage sowie eine Aufzugsanlage, bei der die Tragmittel über eine Tragmittelendverbindung befestigt sind.The invention relates to a Tragmittelendverbindung for fastening a support means of an elevator system and an elevator installation, in which the support means are fastened via a Tragmittelendverbindung.
Die Tragmittel für eine Aufzugskabine müssen im Aufzugsschacht sicher befestigt werden, um die auftretenden Kräfte auf eine Tragstruktur, welche im Aufzugsschacht angeordnet ist, zu übertragen. Die Tragmittel, beispielsweise Seile oder auch Riemen werden bei der Montage mit ihren Endstücken in den Tragmittelendverbinder befestigt. In der Regel wird hierzu eine Schlaufe in das Seil, bzw. den Riemen gelegt und das Tragmittel wird im Tragmittelendverbinder eingeklemmt, beispielsweise durch einen Keil, der einen Anpressdruck auf das Seil oder den Riemen ausübt, so dass dieses/dieser gegen das Gehäuse des Tragmittelendverbinders gepresst wird und nicht ausrauschen kann.The suspension means for an elevator car must be securely fastened in the elevator shaft in order to transmit the forces which occur to a supporting structure which is arranged in the elevator shaft. The support means, such as ropes or belts are fastened during assembly with their end pieces in the Tragmittelendverbinder. In general, this is a loop in the rope, or set the belt and the support means is clamped in Tragmittelendverbinder, for example, by a wedge, which exerts a contact pressure on the rope or the belt, so that this / this against the housing of Tragmittelendverbinders is pressed and can not exude.
Alternativ ist bekannt, eine Schlaufe eines Tragmittelendstücks derart um zwei Umschlingungselemente zu legen, dass zwischen den gegenläufigen Bereichen der Schlaufe ein derart hoher Reibwert besteht, dass das Tragmittel sich selbst zwischen den zwei Umschlingungselementen festklemmt. Zusätzlich zur Umschlingung kann auch hier noch einen Anpressdruck eines Gehäuseteils auf das Tragmittel ausgeübt werden.Alternatively, it is known to lay a loop of Tragmittelendstücks so two wrap elements that between the opposing areas of the loop such a high coefficient of friction is that the support means itself clamped between the two wrap elements. In addition to the looping, a contact pressure of a housing part on the suspension element can also be exerted here.
Ein Tragmittelendverbinder, bei dem das Tragmittel um zwei Umschlingungselemente geschlungen wird, ist beispielsweise aus der
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Tragmittelendverbindung anzugeben, bei der das Fixieren des zweiten Umschlingungselements verbessert wird.The object of the present invention is to provide a Tragmittelendverbindung in which the fixing of the second wrap element is improved.
Die Aufgabe wird gelöst durch eine Tragmittelendverbindung zur Befestigung eines Tragmittels einer Aufzugsanlage, mit einem Gehäuse, das zwei Seitenwände umfasst, mit mindestens zwei im Wesentlichen zylinderförmigen Umschlingungselementen zur Befestigung des Tragmittels, wobei die Umschlingungselemente sich jeweils zwischen den zwei Seitenwänden erstrecken und wobei das zweite Umschlingungselement als in das Gehäuse einführbarer beweglicher Bolzen ausgebildet ist, mit einem am Gehäuse anbringbarem Fixierungselement zur Fixierung des zweiten Umschlingungselements in dessen Position im Gehäuse dadurch gekennzeichnet, dass das Fixierungselement derart ausgebildet ist, dass es in mindestens eine zwischen den Seitenwänden des Gehäuses zu liegen kommende Vertiefung des zweiten Umschlingungselements eingreift.The object is achieved by a Tragmittelendverbindung for attachment of a suspension element of an elevator system, comprising a housing comprising two side walls, with at least two substantially cylindrical Umschlingungselementen for attachment of the support means, wherein the wrap each extending between the two side walls and wherein the second wrap element designed as a movable bolt can be inserted into the housing, with a attachable to the housing fixing element for fixing the second wrapping element in its position in the housing, characterized in that the fixing element is designed such that it is in at least one between the side walls of the housing coming to recess engages the second wrapping element.
Der Erfindung liegt die Erkenntnis zugrunde, dass die Fixierung eines in das Gehäuse eingeführten Bolzens, welcher das zweite Umschlingungselement darstellt, besonders einfach erfolgen kann, wenn dieser Bolzen eine Vertiefung aufweist, in die ein Fixierungselement, welches an dem Gehäuse angebracht werden kann, eingreift. Der Bolzen kann dann gegen das Fixierungselement und somit auch gegen das Gehäuse nicht mehr verschoben werden. Dadurch ist der Bolzen in seiner Lage im Gehäuse fixiert. Die Vertiefung kann hierbei in Längs- oder in Querrichtung des Bolzens verlaufen. Wichtig für die Funktion ist, dass das Fixierungselement in seiner Position im Verhältnis zum Gehäuse stabil bleibt.The invention is based on the finding that the fixing of a bolt introduced into the housing, which constitutes the second belt element, can be carried out particularly simply if this bolt has a recess into which a fixing element, which can be attached to the housing, engages. The bolt can then no longer be moved against the fixing element and thus also against the housing. As a result, the bolt is fixed in its position in the housing. The depression can in this case run in the longitudinal or in the transverse direction of the bolt. Important for the function is that the fixing element remains stable in its position relative to the housing.
Dies wird insbesondere dadurch erreicht, dass das Fixierungselement derart ausgebildet ist, dass es am Gehäuse, insbesondere an einem unteren Joch des Gehäuses fest verbindbar ist. Jegliche Kraft, die durch Verschieben des Bolzens gegen das Fixierungselement entsteht, kann dadurch auf das Gehäuse übertragen werden. Durch seine Befestigung am Gehäuse ist das Fixierungselement gegen vom Bolzen übertragene Kräfte abgesichert und kann damit die Lage des Bolzens im Gehäuse sichern.This is achieved in particular by the fact that the fixing element is designed such that it is firmly connected to the housing, in particular on a lower yoke of the housing. Any force caused by displacement of the bolt against the fixing element can thereby be transferred to the housing. By its attachment to the housing is the fixing element secured against forces transmitted by the bolt and can thus secure the position of the bolt in the housing.
Eine weitere vorteilhafte Ausbildung der Erfindung ist dadurch gekennzeichnet, dass das Fixierungselement eine sich im Wesentlichen parallel zu einer Seitenwand des Gehäuses in das Gehäuse hinein erstreckende Fläche aufweist, wobei die Fläche eine zur Querschnittsform des zweiten Umschlingungselements komplementäre Einbuchtung aufweist, und wobei die Einbuchtung derart dimensioniert ist, dass sie das zweite Umschlingungselement nur an seiner mindestens einen Vertiefung aufnehmen kann. Dies hat den Vorteil, dass die Vertiefung des Bolzens nicht punktförmig sein muss, sondern sich über eine längere Strecke erstrecken kann. Die Einbuchtung und die mit ihr korrespondierende Vertiefung des Bolzens bzw. des Umschlingungselements weisen somit einen grösseren Bereich auf, über den hinweg sie ineinander greifen. Hierdurch wird eine höhere Sicherheit bei der Fixierung des Bolzens erreicht, da die Wahrscheinlichkeit, dass das Fixierungselement aus der Vertiefung des Bolzens herausrutscht, minimiert wird.A further advantageous embodiment of the invention is characterized in that the fixing element has a substantially parallel to a side wall of the housing in the housing extending surface, wherein the surface has a complementary to the cross-sectional shape of the second wrap element indentation, and wherein the indentation sized is that it can accommodate the second wrap only at its at least one recess. This has the advantage that the recess of the bolt need not be punctiform, but may extend over a longer distance. The indentation and the corresponding recess of the bolt or the wrapping element thus have a larger area over which they engage with each other. As a result, a higher security in the fixation of the bolt is achieved because the likelihood that the fixing element slips out of the recess of the bolt is minimized.
Zudem ist es vorteilhaft, dass der Bolzen nur an der Stelle mit seiner Vertiefung von dem Fixierungselement aufgenommen werden kann, so dass bei der Montage sichergestellt wird, dass das Fixierungselement bzw. der Bolzen im Verhältnis zur Position des Fixierungselements optimal sitzt. Wird das Fixierungselement derart am Gehäuse befestigt, dass die Fläche mit ihrer Einbuchtung nicht direkt in die Vertiefung des Bolzens eingreift, so kann der Bolzen in der Einbuchtung gar nicht aufgenommen werden und das Fixierungselement kann mit seiner Fläche nicht tief genug ins Gehäuse eindringen, so dass einem Monteur sofort auffällt, dass das Fixierungselement nicht richtig positioniert sein kann. Nur wenn die Einbuchtung den Bolzen in sich aufnimmt, ist das Fixierungselement korrekt am Gehäuse angebracht und steht nicht über die Seitenwände des Gehäuses hinaus.In addition, it is advantageous that the bolt can be received only at the point with its recess of the fixing element, so that it is ensured during assembly that the fixing element or the bolt is optimally seated in relation to the position of the fixing element. If the fixing element is fastened to the housing in such a way that the surface with its indentation does not engage directly in the recess of the bolt, then the bolt can not be received in the indentation and the fixing element can not penetrate deep enough into the housing with its surface, so that a fitter immediately noticed that the fixing element can not be properly positioned. Only when the indentation receives the bolt in itself, the fixing element is correctly attached to the housing and does not protrude beyond the side walls of the housing.
Eine weitere vorteilhafte Ausbildung der Erfindung ist dadurch gekennzeichnet, dass die sich in das Gehäuse hinein erstreckende Fläche des Fixierungselements derart dimensioniert ist, dass die Flanken der Einbuchtung sich über den Mittelpunkt des Querschnitts des zweiten Umschlingungselements hinaus erstrecken. Hierdurch ist gewährleistet, dass auch wenn das Fixierungselement nicht ganz optimal am Gehäuse angebracht ist, die Flanken noch in die Vertiefung auf dem Bolzen eingreifen und diesen somit vor einer Lateralverschiebung schützen. Auch in diesem Fall kann also der Bolzen nicht aus dem Gehäuse gleiten, was dazu führen würde, dass das um ihn geschlungene Auge des Tragmittels nicht mehr gesichert wäre und das Tragmittel aus der Tragmittelendverbindung ausrauschen würde.A further advantageous embodiment of the invention is characterized in that extending into the housing surface of the fixing element is dimensioned such that the flanks of the recess extending beyond the center of the cross section of the second wrapper addition. This ensures that even if the fixing element is not quite optimally mounted on the housing, the flanks still engage in the recess on the bolt and thus protect it from a lateral displacement. Also in this case, therefore, the bolt can not slide out of the housing, which would cause that the looped around him eye of the support means would no longer be secured and the support means would emanate from the Tragmittelendverbindung.
Eine weitere vorteilhafte Ausbildung der Erfindung ist dadurch gekennzeichnet, dass die zwischen dem unteren Joch des Gehäuses und dem zweiten Umschlingungselement angeordnete Flanke des Fixierungselements derart dimensioniert ist, dass sie den Platz zwischen Joch und Umschlingungselement im Wesentlichen ausfüllt. Dies hat den Vorteil, dass selbst wenn das Fixierungselement gelöst wird und die Fläche mit der Einbuchtung den Bolzen nicht mehr ganz in sich aufnimmt, weil sie schräg vom Bolzen weggezogen wird, immer noch die Flanke des Fixierungselements in die Vertiefung eingreift. Ein Lösen des Fixierungselement und ein Wegziehen oder Wegheben schräg nach unten führt immer noch nicht dazu, dass der Bolzen eine Seitwärtsbewegung ausführen kann. Somit ist der Bolzen auch gesichert, wenn das Fixierungselement sich ein wenig gelöst hat und nicht mehr 100-prozentig fest mit dem Gehäuse verbunden ist. Lediglich wenn das Fixierungselement ganz vom Gehäuse abgetrennt ist, bsp. durch einen Monteur, der es abgeschraubt hat, ist der Bolzen frei und kann aus dem Gehäuse genommen werden.A further advantageous embodiment of the invention is characterized in that the flank of the fixing element arranged between the lower yoke of the housing and the second looping element is dimensioned such that it substantially fills the space between the yoke and the looping element. This has the advantage that even if the fixing element is released and the surface with the indentation no longer completely absorbs the bolt, because it is pulled away obliquely from the bolt, the flank of the fixing element still engages in the recess. Loosening the fixation member and pulling away or raising obliquely downwards still does not cause the bolt to move sideways. Thus, the bolt is also secured when the fixing element has loosened a little and is no longer 100 percent firmly connected to the housing. Only if the fixing element is completely separated from the housing, bsp. by a fitter who unscrewed it, the bolt is free and can be removed from the housing.
Eine weitere vorteilhafte Ausbildung der Erfindung ist dadurch gekennzeichnet, dass ein zu einer Schlaufe gelegtes Tragmittelendstück derart in dem Gehäuse anordbar ist, dass die zwei gegenläufigen Bereiche der Schlaufe das erste Umschlingungselement umschlingen und dass das zweite Umschlingungselement durch das Auge der Schlaufe steckbar ist. Dies ist für den Monteur vor Ort besonders vorteilhaft, da er lediglich eine einfache Schlaufe in das Tragmittel legen muss. Diese wird in das Gehäuse und um das erste Umschlingungselement herumgeführt und bildet dann automatisch ein Auge, in das auf einfache Weise der Bolzen bzw. das zweite Umschlingungselement gesteckt werden kann. In Zusammenhang mit dem Fixierungselement, welches dann über den Bolzen gelegt, bzw. gestülpt werden kann und anschliessend befestigt, ist somit eine besonders einfache Montage der Tragmittelendverbindung bzw. des Tragmittels in der Tragmittelendverbindung und eine einfache Fixierung des Tragmittels in der Tragmittelendverbindung möglich.A further advantageous embodiment of the invention is characterized in that a support means end piece laid to form a loop can be arranged in the housing in such a way that the two opposing regions of the loop wrap around the first wrapping element and the second wrapping element can be inserted through the eye of the loop. This is particularly advantageous for the fitter on site, as he only has to put a simple loop in the suspension element. This is guided around in the housing and around the first wrapping element and then automatically forms an eye into which the bolt or the second wrapping element can be easily inserted. In connection with the fixing element, which can then be placed over the bolt or slipped and then attached, thus a particularly simple mounting of Tragmittelendverbindung or the support means in the Tragmittelendverbindung and a simple fixation of the support means in the Tragmittelendverbindung is possible.
Im Folgenden wird die Erfindung anhand der Figuren näher beschrieben und erläutert.The invention will be described and explained in more detail below with reference to the figures.

An der Vorderseite ist das Gehäuse im Wesentlichen offen. Das Tragmittel 2 wird in dem Gehäuse 1 so angeordnet, dass ein bewegliches und in das Gehäuse einführbares Umschlingungselement 4 in dem Auge einer Schlaufe des Tragmittels zu liegen kommt.

Unter das Fixierungselement bzw. zwischen Fixierungselement und Tragmittel 2 kann hierbei noch eine Rolle bzw. ein stiftförmiges Element 56 angebracht werden. Das stiftförmige Element 56 kann aus Metall oder aus einem anderen, nicht brennbaren, insbesondere nicht elektrisch leitendem Material sein. Es wird beim Festschrauben des Fixierungselements 5 quasi zwischen Fixierungselement und Tragmittel eingeklemmt und übt somit auf das Ende des Tragmittels einen Druck aus. Dieser dient zur zusätzlichen Sicherung des Tragmittels 2 im Gehäuse. Insbesondere im Brandfall, wenn ein Elastomer, welches im Tragmittel 2 angeordnete metallene, lasttragende Zugträger umgibt, wegschmilzt, wird nicht mehr genug Druck auf die Zugträger ausgeübt und die Reibkraft des Tragmittels reicht auch nicht mehr aus, um es im Tragmittelendverbinder zu halten. In diesem Fall wird die Rolle, die nicht brennbar ist, in den Spalt 15 zwischen dem ersten Joch 13 und dem zweiten Joch17 hineingezogen (
Die zwei Flanken 53, 54 der Einbuchtung sind soweit heruntergezogen, dass sie über die Mitte des Umschlingungselements herausragen. Hierdurch ist gewährleistet, dass auch wenn das Fixierungselement 5 nicht 100-prozentig sitzt, die Fläche 51 des Fixierungselements in der Lage ist, das Umschlingungselement 4 in seiner Position zu halten. Zur verbesserten Fixierung ist die Flanke 53 in ihrer Breite so gewählt, dass bei Einführen des Fixierungselements 5 in das Gehäuse 1 für die Flanke 53 gerade so viel Platz zwischen dem Joch und dem mit dem Tragmittel 2 umschlungenen Bolzen bzw. Umschlingungselement 4 besteht, dass das Fixierungselement dort platziert werden kann. Eine Rotationsbewegung des gesamten Fixierungselements, wenn beispielsweise die Fläche 57 nicht mehr ganz fest mit dem Joch 13 verschraubt ist, kann somit nicht gleich zu einer Lösung des Bolzens 4 führen. Die Flanke würde in dem Fall, dass das Fixierungselement 5 sich ein wenig löst und wackelt, trotzdem noch nah genug am Bolzen sein und bei Verdrehen sogar noch in die Vertiefung 41 eingreifen. Insbesondere im Zusammenhang mit einer ringförmigen Vertiefung im Bolzen ist gewährleistet, dass die Flanke immer eingreift. Eine derartige ringförmige Vertiefung im Bolzen, also eine umlaufende Nut hat weiterhin den Vorteil, dass der Bolzen nur in Bezug auf die seitliche Ausrichtung hin justiert werden muss. Ein Drehen des Bolzens im Gehäuse, um ihn in eine Position zu bringen, in der das Fixierungselement eingreifen kann ist nicht notwendig.The two
