Abstract

The invention relates to a wedge action connector, especially for construction equipment, with an extended support, a releasably securable holding component longitudinally movable thereon which is stable in position at various longitudinal points on the support, which has an aperture at least partially surrounding a support with a limited range of movement, the cross-section of which is somewhat larger in at least one direction transversely to the support than the latter's corresponding cross-section, and with a securing wedge having two impact ends, the cross-section of which increases in its longitudinal direction, which can also be inserted through a safety aperture merging into the acceptance aperture and which in the secured position, bearing laterally on the support, clamps the holding component securely in position against the support. To improve handling and reduce the space required, the invention proposes that the safety wedge is arc-shaped and both its impact ends point roughly in the same direction.

Description

Die Erfindung betrifft eine Keilverbindung, insbesondere für Baugeräte, mit einem langgestreckten Halteträger, mit einem darauf in dessen Längsrichtung verschiebbaren sowie an verschiedenen Längspositionen des Halteträgers lagestabil, lösbar fixierbaren Befestigungslement, das eine den Halteträger mit begrenztem Bewegungsspiel zumindest teilweise umgreifende Aufnahmeöffnung aufweist, deren Querabmessung in zumindest einer Richtung quer zur Längsrichtung des Halteträgers etwas größer als dessen entsprechende Querabmessung ist, und mit einem zwei Schlagenden aufweisenden Sicherungskeil, dessen Querschnitt in seiner Längsrichtung zunimmt, der ferner durch eine in die Aufnahmeöffnung übergehende Sicherungsöffnung in dem Befestigungselement steckbar ist und der im Befestigungszustand unter seitlicher Anlage an dem Halteträger das Befestigungselement gegen den Halteträger lagefixierend verspannt.The invention relates to a wedge connection, in particular for construction equipment, with an elongated support bracket, with a fastener that is displaceable thereon in the longitudinal direction thereof and can be fixed in position in various longitudinal positions of the support bracket, and which has a receiving opening at least partially encompassing the support bracket with limited movement play, the transverse dimension of which in at least one direction transverse to the longitudinal direction of the support bracket is slightly larger than its corresponding transverse dimension, and with a two-ended securing wedge, the cross-section of which increases in its longitudinal direction, which can also be inserted into the fastening element through a securing opening which merges into the receiving opening and which is in the fastening state under lateral attachment to the support bracket braced the fixing element against the support bracket.

Bei derartigen Keilverbindungen, z.B. in der Patenschrift FR-A-2 153 538, weisen die Schlagenden des im wesentlichen geraden Sicherungskeils in zueinander entgegengesetzte Richtungen. Deshalb muß zum Befestigen und zum Lösen der Keilverbindung an beiden Schlagenden genügend Freiraum zur Verfügung stehen. Da der Sicherungskeil im allgemeinen in Längsrichtung des Halteträgers verläuft, sind darauf anzubringende Befestigungselemente mit ausreichendem Längsabstand zu störenden Hindernissen anzuordnen, wie zu einer Wand oder einem weiteren Befestigungselement auf demselben Längsträger. Wenn dagegen der Sicherungskeil zur Vermeidung dieses Raumproblems quer zur Längsrichtung des Halteträgers angebracht wird, besteht die Problematik darin, daß die Schlagkräfte quer auf den Halteträger auftreffen, was leichter zu Schädigungen führen kann. Außerdem ist dann ein ausreichender Abstand zu seitlich benachbarten Halteträgern einzuhalten.In the case of such wedge connections, for example in patent specification FR-A-2 153 538, the striking ends of the essentially straight securing wedge point in opposite directions to one another. Therefore, there must be enough free space at both ends to fasten and loosen the wedge connection. Since the securing wedge generally in the longitudinal direction of the support beam runs, fasteners to be attached to them are to be arranged with a sufficient longitudinal distance from disturbing obstacles, such as to a wall or another fastener on the same side member. If, on the other hand, the securing wedge is installed transversely to the longitudinal direction of the holding bracket to avoid this space problem, the problem is that the impact forces hit the holding bracket transversely, which can more easily lead to damage. In addition, a sufficient distance to the adjacent support beams must then be maintained.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine verbesserte Keilverbindung der im Oberbegriff von Anspruch 1 genannten Art zu schaffen, bei der eine günstigere Raumausnutzung möglich ist und die leichter sowie zweckmäßiger zu handhaben istThe present invention is therefore based on the object of providing an improved wedge connection of the type mentioned in the preamble of claim 1, in which more favorable use of space is possible and which is easier and more expedient to handle

Zur Lösung der gestellten Aufgabe zeichnet sich eine Keilverbindung der im Oberbegriff von Anspruch 1 genannten Art erfindungsgemäß durch die im Kennzeichen dieses Anspruchs aufgeführten Merkmale aus. Hierdurch wird erreicht, daß für das die Verbindung fixierende Hineinschlagen und für das die Verbindung lösende Herausschlagen des Sicherungskeils im wesentlichen dieselbe Schlagrichtung gilt. Dieses ergibt eine wesentlich einfachere Handhabung, beispielsweise dann, wenn beim genauen Einrichten der Längsposition eines am Längsträger festzulegenden Befestigungselements ein abwechselndes Fixieren und Lösen notwendig ist. Außerdem besteht ein deutlich kleinerer Platzbedarf, so daß mehrere Verbindungen auf engerem Raum hergestellt werden können, ohne sich diese bezüglich der Handhabung gegenseitig stören.To achieve the object, a wedge connection of the type mentioned in the preamble of claim 1 is characterized according to the invention by the features listed in the characterizing part of this claim. It is hereby achieved that essentially the same direction of impact applies to the fixing and the knocking out of the securing wedge. This results in a much simpler handling, for example when an alternate fixing and loosening is necessary when the longitudinal position of a fastening element to be fixed on the longitudinal member is set precisely. In addition, there is a significantly smaller space requirement, so that several connections can be made in a narrower space without interfering with each other in terms of handling.

Gemaß den Ausgestältungen der Ansprüche 2 bis 4 bestehen mehrere Möglichkeiten der Keilgestaltung durch Verändern seiner Breite und/oder seiner Dicke. Dadurch kann die Formgebung des Sicherungskeils der jeweiligen Anwendung optimal angepaßt werden.According to the embodiments of claims 2 to 4, there are several possibilities of wedge design by changing its width and / or its thickness. As a result, the shape of the securing wedge can be optimally adapted to the respective application.

Besonders zweckmäßig ist dabei eine Veränderung der Keilbreite.A change in the wedge width is particularly expedient.

Die Weiterbildung von Anspruch 5 führt zu einem gleichmäßigen Funktionsverhalten bei der Handhabung des Sicherungskeils. Demgegenüber ermöglicht die Weiterbildung von Anspruch 6 ein anfänglich schnelles grobes Fixieren und wegen der dann kleineren Querschnittsvergrößerung sehr große Fixierkräfte am Ende des fixierenden Hineinschlagens des Sicherungskeils. Dieses fördert die Handhabung und die Zuverlässigkeit der Keilverbindung.The development of claim 5 leads to a uniform functional behavior when handling the safety wedge. In contrast, the development of claim 6 enables an initially quick, coarse fixing and, because of the then smaller enlargement of the cross section, very large fixing forces at the end of the fixing wedge of the securing wedge. This promotes the handling and the reliability of the wedge connection.

Die Bauform von Anspruch 7 ist besonders einfach und preiswert herstellbar. Dazu ist es lediglich erforderlich, das aus dem Bandmaterial beispielsweise ausgestanzte oder ausgesägte, geeignet geformte Keilgebilde quer zur Bandebene ausreichend weit zu biegen, damit die Schlagenden etwa in dieselbe Richtung weisen.The design of claim 7 is particularly simple and inexpensive to manufacture. All that is required is to bend the suitably shaped wedge structure, for example punched out or sawn out of the band material, sufficiently far transversely to the band plane so that the striking ends point approximately in the same direction.

Bei der Ausgestaltung von Anspruch 8 ergeben sich wegen der Halbringform besonders günstige Kraftübertragungsverhältnisse. Dieses gilt insbesondere in Verbindung mit einem solchen Sicherungskeil, bei dem sich nur dessen Breite (quer zur Krümmungsebene) verändert Der Begriff Halbringform soll auch solche Sicherungskeile umfassen. die mehr oder weniger als 180 Grad gekrümmt sind (hiervon um weniger als 90 Grad abweichend).In the embodiment of claim 8, particularly favorable power transmission ratios result because of the half-ring shape. This applies in particular in connection with such a locking wedge, in which only its width (transverse to the plane of curvature) changes. The term semi-ring shape is also intended to include such locking wedges. that are more or less than 180 degrees curved (deviating from them by less than 90 degrees).

Die endseitigen Schlagglieder gemäß den Weiterbildungen der Ansprüche 9 bis 13 erlauben eine sehr günstige Handhabung beim Schlagen des Sicherungskeils. Außerdem kann die Formgebung und/oder die Anbringung der Schlagglieder der jeweiligen Anwendung, wie den Raumverhältnissen, geeignet angepaßt werden.The end striking members according to the developments of claims 9 to 13 allow very favorable handling when hitting the safety wedge. In addition, the shape and / or the attachment of the striking elements of the respective application, such as the spatial conditions, can be suitably adapted.

Je nach Anwendungsfall kann die Ausbildung von Anspruch 14 oder 15 gewählt werden. Im allgemeinen dürfte die Bauform von Anspruch 14 aus Stabilitätsgründen günstiger sein, weil die Schlagkräfte dann in Längsrichtung des Halteträgers verlaufen, und nicht quer dazu. Wenn jedoch mehrere Befestigungselemente dicht hintereinander am Halteträger festzulegen sind, kann die Bauform aus Anspruch 15 günstiger oder erforderlich sein.Depending on the application, the training of claim 14 or 15 can be chosen. In general, the design of claim 14 should be cheaper for reasons of stability, because the impact forces then run in the longitudinal direction of the support beam and not transversely to it. However, if several fasteners are to be fixed in close proximity to one another on the support bracket, the design from claim 15 may be cheaper or necessary.

Die Bauform aus Anspruch 16 hat den Vorteil, daß das Befestigungselement wegen der Gabelform raumsparend seitlich auf den Halteträger aufsetzbar ist, also nicht in Längsrichtung auf diesen aufgeschoben werden muß. Andererseits kann die Bauform aus Anspruch 17 immer dann, wenn ein längsgerichtetes Aufschieben möglich ist, bei gleichem Materialaufwand Stabilitätsvorteile haben.The design of claim 16 has the advantage that the fastener can be placed laterally on the support bracket to save space because of the fork shape, that is, it does not have to be pushed onto the support bracket in the longitudinal direction. On the other hand, the design from claim 17 can always have stability advantages with the same material expenditure whenever a longitudinal pushing open is possible.

Bei der Variante aus Anspruch 18 befindet sich der Sicherungskeil am Ende des Befestigungselements, so daß dieses nicht die Handhabung des Sicherungskeils stört.In the variant from claim 18, the securing wedge is located at the end of the fastening element, so that this does not interfere with the handling of the securing wedge.

Für bestimmte Anwendungszwecke kann die Bauform aus Anspruch 19 zweckmäßig und ausreichend sein.For certain applications, the design of claim 19 can be useful and sufficient.

Das Fußwiderlager 38 ist um eine quer zum Halteträger 10 verlaufende Achse schwenkbar, so daß die Bohlenhalterung auch seitlich an einer Treppenstufe fixierbar ist, deren Unterseite der Treppensteigung entsprechend schräg verläuft. Mehrere an dem Halteträger 10 befestigte Bohlenhalter 40 dienen zum Einlegen von Baubohlen.At the end of the support bracket 10 of FIGS. 7 and 8 there is a stationary foot abutment 38 which, together with the adjustable fastening element 12, represents the clamp-like structure for clamping the entire screed holder. The foot abutment 38 can be pivoted about an axis running transversely to the support beam 10, so that the screed holder can also be fixed laterally on a stair step, the underside of which is inclined corresponding to the stair incline. A plurality of screed holders 40 fastened to the support beam 10 serve to insert screeds.

Einander entsprechende Teile der ersten und zweiten Ausführungsformen tragen dieselben Bezugszeichen. Nachfolgend wird die erste Ausführungsform an den Figuren näher erläutert, wobei diese Erläuterung sinngemäß genauso für die zweite Ausführungsform gilt.Corresponding parts of the first and second embodiments have the same reference numerals. The first embodiment is explained in more detail below with reference to the figures, this explanation correspondingly also valid for the second embodiment.

Das Befestigungselement 12 hat eine den Halteträger 10 zumindest teilweise umschließende Aufnahmeöffnung 14. Da das Befestigungselement 12 bei den dargestellten Ausführungsformen seitlich auf den Halteträger 10 aufgebracht werden muß, ist die Aufnahmeöffnung 14 an einer Seite offen, also U-förmig ausgebildet bzw. gabelartig geöffnet (Fig.3 und 5).The fastening element 12 has a receiving opening 14 which at least partially surrounds the holding carrier 10. Since the fastening element 12 has to be applied laterally to the holding carrier 10, the receiving opening 14 is open on one side, that is to say U-shaped or fork-shaped ( Fig. 3 and 5).

Ein Sicherungskeil 16 dient zum Fixieren des Befestigungselements 12 am Halteträger 10 und ist im vorliegenden Fall (beispielsweise gemäß Fig. 6) um etwa 180 Grad halbringförmig gekrümmt. Der Sicherungskeil 16 weist an seinen etwa in die gleiche Richtung weisenden Schlagenden 18, 20 hieran angeschweißte, plattenförmige, etwa radial ausgerichtete Schlagglieder auf. Diese erleichtern das Aufbringen der zum Fixieren und Lösen des Sicherungskeils 16 erforderlichen Schlagkräfte.A securing wedge 16 is used to fix the fastening element 12 to the support bracket 10 and in the present case (for example according to FIG. 6) is curved in the shape of a semi-ring by approximately 180 degrees. The securing wedge 16 has plate-shaped, approximately radially oriented striking members welded to its striking ends 18, 20 pointing approximately in the same direction. These facilitate the application of the impact forces required for fixing and releasing the securing wedge 16.

Der dargestellte Sicherungskeil 16 hat in seiner Krümmungsebene eine über seine Länge etwa gleichbleibende Dicke (Fig. 6), während die quer dazu gemessene Breite des Sicherungskeils 16 von seinem Schlagende 20 zu seinem Schlagende 18 zunimmt (Fig. 1 bis 5). Grundsätzlich ist es stattdessen oder auch zusätzlich möglich, die in der Krümmungsebene gemessene Dicke des Sicherungskeils 16 zwischen den Schlagenden 20 und 18 ansteigen zu lassen, wie es bei der zweiten Ausführungsform (Fig. 7) ersichtlich ist.The securing wedge 16 shown has an approximately its length in its plane of curvature constant thickness (Fig. 6), while the transverse width of the locking wedge 16 increases from its striking end 20 to its striking end 18 (Fig. 1 to 5). In principle, instead of or in addition, it is possible to increase the thickness of the securing wedge 16 measured in the plane of curvature between the striking ends 20 and 18, as can be seen in the second embodiment (FIG. 7).

Eine Sicherungsöffnung 22 zum Aufnehmen des Sicherungskeils 16 durchsetzt das freie Ende des Befestigungselements 12 sowie die Aufnahmeöffnung 14 und verläuft im vorliegenden Fall quer zu dieser. Sie sorgt dafür, daß der in Einschlagrichtung in seinem Querschnitt zunehmende Sicherungskeil 16 den quer zur Längsrichtung des Halteträgers 10 gemessenen Abstand (in den Fig. 1 bis 5 vertikal verlaufend) zwischen dem Rand des Halteträgers 10 und der Begrenzung der Sicherungsöffnung 22 vergrößert. Dadurch wird das Befestigungselement 12 in seiner Längsrichtung gegen den Halteträger 10 gepreßt und somit hieran fixiert.A securing opening 22 for receiving the securing wedge 16 passes through the free end of the fastening element 12 and the receiving opening 14 and in the present case runs transversely to the latter. It ensures that the securing wedge 16, which increases in cross section in the direction of impact, increases the distance measured transversely to the longitudinal direction of the holding support 10 (vertical in FIGS. 1 to 5) between the edge of the holding support 10 and the boundary of the securing opening 22. Characterized the fastening element 12 is pressed in its longitudinal direction against the support bracket 10 and thus fixed thereon.

Die bei der ersten Form U-förmige, sich nach unten öffnende Aufnahmeöffnung 14 ist an ihrem oberen Ende von einem eingeschweißten Gabelverbindungsglied 24 und seitlich von Gabelschenkeln 26 des Befestigungselements 12 begrenzt. Die Sicherungsöffnung 22 weist an Ihrer einen Seite ein stabiles eingeschweißtes Keilanlageglied 28 auf, das die Schlagkräfte auffängt.The receiving opening 14, which is U-shaped in the first form and opens downward, is delimited at its upper end by a welded-in fork connecting member 24 and laterally by fork legs 26 of the fastening element 12. The securing opening 22 has on one side a stable welded-in wedge contact member 28 which absorbs the impact forces.

Wenn der Sicherungskeil 16 durch Schlagen auf sein dickeres Schlagende 18 eingetrieben wird, bewegt er sich unter richtungsumlenkender Anlage am Keilanlageglied 28 zunehmend durch die Sicherungsöffnung 22, wobei das Befestigungslement 12 am Halteträger 10 verspannt wird. Wenn dagegen auf das Schlagende 20 geschlagen wird, bewegt er sich umgekehrt, und die Spannverbindung wird aufgehoben.When the safety wedge 16 is driven in by striking its thicker end 18, it moves increasingly under the direction-changing system on the wedge contact member 28 through the safety opening 22, the fastening element 12 being braced on the support bracket 10. On the other hand, if the striking end 20 is struck, it moves in reverse and the tension connection is released.

Da bei den beiden Ausführungsformen die Sicherungsöffnung 22 quer zur Längsrichtung des Halteträgers 10 verläuft, erstrecken sich die Schlagenden 18, 20 des Sicherungskeils 16 der dargestellten Ausführungsformen im Einbauzustand etwa in Langsrichtung des Halteträgers 10. Dadurch werden die Schlagkräfte sehr günstig vom Halteträger 10 aufgefangen Grundsätzlich ist es aber auch möglich, daß die Sicherungsöffnung in Längsrichtung - oder auch schräg dazu - verläuft. Dann würden die Schlagenden 18, 20 im Einbauzustand quer - oder schräg - zur Langsrichtung des Halteträgers 10 weisen.Since in the two embodiments, the securing opening 22 transverse to the longitudinal direction of the Holding bracket 10 extends, the striking ends 18, 20 of the securing wedge 16 of the illustrated embodiments extend in the installed state approximately in the longitudinal direction of the holding bracket 10. This, the impact forces are very cheaply absorbed by the holding bracket 10 In principle, it is also possible that the securing opening in the longitudinal direction - or also at an angle to it - runs. Then the striking ends 18, 20 in the installed state would point transversely or obliquely to the longitudinal direction of the holding support 10.

Wenn bei einer Bauvariante stattdessen nur die in der Krümmungsebene gemessene Dicke des Sicherungskeils veränderlich wäre, so wäre dieser bei der ersten Ausführungsform mit nach unten oder oben weisenden Schlagenden und bei der zweiten Ausführungsform mit nach vorne oder hinten weisenden Schlagenden einzubauen. Grundsätzlich könnten auch die Breite und die Dicke des Sicherungskeils nach Art einer Pfeilspitze veränderlich sein.If, instead, only the thickness of the securing wedge measured in the plane of curvature were variable in a construction variant, this would have to be installed with striking ends pointing down or up in the first embodiment and striking ends pointing forward or back in the second embodiment. In principle, the width and the thickness of the securing wedge could also be variable in the manner of an arrowhead.

Die Keilverbindung der vorliegenden Erfindung ist äußerst vielseitig einsetzbar, beispielsweise in der Bauindustrie bei Baugeräten. Die Keilform kann vielfältig abgewandelt werden. Wichtig ist dabei jedoch, daß die Schlagenden nicht wie beim Stand der Technik in einander entgegengesetzte Richtungen, sondern zumindest etwa in dieselbe Richtung weisen. Dabei sollte eine an sich mögliche Richtungsabweichung der beiden Schlagenden gegenüber 180 Grad weniger als ± 90 Grad betragen.The wedge connection of the present invention is extremely versatile, for example in the construction industry for construction equipment. The wedge shape can be modified in many ways. It is important, however, that the striking ends do not point in opposite directions as in the prior art, but at least approximately in the same direction. A possible deviation in direction of the two striking ends from 180 degrees should be less than ± 90 degrees.
