It offers from the DE 197 56 598 A1 known solution in particular the ability to make the connection and disconnection by only a single operation, namely a compression of the two holding elements in the axial direction.
- the known solution has various actuating and latching means which, in cooperation with a plurality of guide means in a stop position of the second holding element for connecting or releasing, cause a relative movement of the first and second holding elements in a plane perpendicular to the axial direction.
- actuating and latching means which, in cooperation with a plurality of guide means in a stop position of the second holding element for connecting or releasing, cause a relative movement of the first and second holding elements in a plane perpendicular to the axial direction.
- a disadvantage of the known from the prior art device for releasably connecting strings is that the individual elements of the Device are constructed relatively complex.
- a third element in the form of a so-called sliding part is provided, which cooperates in a special way with the two holding elements to initiate the desired relative movement, which is required for locking or releasing the locking. Due to the requirement of a third component, however, the device is relatively complex and thus costly in their production. In addition, the handling of the device is difficult, the more components it has.
- the present invention is therefore based on the object to provide a novel or improved device for releasably connecting strings, in which the disadvantages or limitations described in connection with the prior art are avoided.
- the solution according to the invention is based on a special embodiment of the bolt-like second holding element. According to the invention it is provided that this is designed as a one-piece component, which has a first, so-called. Actuating parts, and a second, so-called. Detent parts having area, both areas are interconnected.
- this embodiment of the second retaining element according to the invention it is now possible to dispense with the sliding part which is still required in the prior art. Instead, all elements or components which effect the particular movement between the first and the second holding element with one another for latching or releasing the latch, are arranged on one of the two holding elements.
- the inventive device for releasably connecting strings accordingly consists exclusively of two separate elements or components, which on the one hand brings advantages in the production and on the other hand advantages in the handling of the device.
- a device for releasably connecting strings which has a sleeve-like first retaining element for a first string and a bolt-like second retaining element for a second string, wherein the second retaining element inserted into the first retaining element and for connecting and detaching the two holding elements in an axial direction is movable and wherein the second holding element actuating and locking parts, which in Collaboration with located on the first holding element guiding and locking parts in a stop position of the second holding element for connecting or releasing cause a relative movement of the first and the second holding element in a plane perpendicular to the axial direction.
- the second holding element is configured as a one-piece component with a first region having the latching parts and a second region having the actuating parts.
- the two areas of the second holding element are arranged one behind the other as seen in the axial direction.
- both areas of the second holding element are flexibly connected to each other.
- the two regions are connected to each other via a connection region, which is designed such that a relative movement of the two regions in the plane perpendicular to the axial direction is made possible.
- the second holding element can be configured in one piece despite everything, since there is always the possibility to design the connection area in a corresponding manner, that the flexible connection is ensured.
- the connection area could be suitably dimensioned.
- Another possibility would be to use a special material for this connection area which has the required flexibility.
- the second holding element could be produced in a multi-component injection molding process. In any case, the solution of the invention has significant advantages over previously used devices, since only two different components must be manufactured and handled, which is cheaper and easier.
- the present invention relates to a measure by which the axial centering of the second holding element is ensured during insertion into the first holding element.
- the first holding element has a bottom-side depression, which cooperates with a conical tip at the front end of the second holding element. In this way, it is ensured that, in principle, there is a suitable alignment of the various latching, actuating and guide parts. This ensures that the various elements also interact as intended.
- FIGS. 1, 2, 3a and 3b first show the general structure of the connecting device according to the invention or the elements used for this purpose.
- the device has two holding elements provided with the reference numerals 1 and 2, wherein a first holding element 1 is designed in the form of a sleeve, while on the other hand a second holding element 2 is designed as a bolt.
- Both holding elements 1 and 2 have at each of an end-side end portion 11 and 7, a conical taper for attaching one or more cords, as shown in the illustrations in the FIGS. 3a and 3b can be removed. By locking the two holding elements 1 and 2 together, these strings can therefore be connected to each other.
- the two holding elements 1 and 2 are designed such that the connection of these or the release of the interconnected elements 1, 2 can be done in a simple manner. In particular, only a single action is required for the connection or the release, namely a compression of both elements in the axial direction. This is achieved by a special embodiment of the two elements, which will be explained below.
- the first support member 1 over a certain length on a cylindrical cavity 12, which is provided for receiving the second bolt-like support member 2 is.
- This cylinder-like cavity 12 is in its end facing the conical end 11 in a slightly narrower sized cavity 13, wherein the transition is achieved by a subsequent to the bottom side of the cavity 12 conical portion 13 a.
- this embodiment in cooperation with a centering part of the second holding element 2, achieves that an axial centering of the second holding element 2 takes place in the first holding element 1.
- the latching or releasing the latching between the two holding elements 1 and 2 is achieved, inter alia, by guiding and locking parts, which are arranged within the cylindrical cavity 12.
- First latching parts 15 are arranged in the input region of the sleeve, whereas the guide parts 20 are arranged in the bottom region of the hollow space 12.
- the embodiment of both the locking parts 15 and the guide members 20 may in particular the illustration in FIG. 5 as well as the two sectional views of the Figures 6a and 6b be removed.
- each locking part 15 and four guide members 20 are provided, which are arranged distributed over the inner circumference of the sleeve. It is important that each one locking part 15 is arranged exactly above a guide member 20.
- Both the latching parts 15 and the guide parts 20 are formed by protruding from the wall of the sleeve 1 in the interior 12 pins which at its upper end two laterally to the longitudinal center axis - for example, at an angle of approximately 45 ° - sloping guide surfaces 16a, 16b or 20a, 20b have.
- a further guide surface 17 is also formed, which in turn extends in relation to the axial direction of the locking parts 15 in an oblique plane.
- the configuration of the second holding element 2 can in particular the representations in the Figures 2 and 7 - 9 be removed.
- the second holding element 2 has a conical taper 5 which, upon insertion of the bolt into the sleeve, comes into contact with the conical region 13a of the first holding element 1 and thereby causes self-centering of the second holding element 2 in the first holding element 1.
- the latching and releasing of the two holding elements 1, 2 is effected by locking parts 30 and actuating parts 35 located on the second holding element 2, which interact in a special way with the guide parts 20 and latching parts 15 of the first holding element 1.
- the particular embodiment of the locking parts 30 and actuators 35 may in particular the representations of Figures 8, 9a and 9b be removed.
- the latching parts 30 are each formed by a shorter side part 31 and a longer side part 32, which are connected to each other on its underside by an obliquely to the axial direction of the support member 2 extending guide surface 33. Between both side parts 31 and 32, which at their upper ends in each case parallel to the guide surface 33 extending chamfers 31a and 32a, thus an open towards the top recess 30a is formed. As FIG. 9a can be removed, four locking parts 30 are arranged distributed on the outside of the second support member 2.
- actuating parts 35 are arranged, which in turn are designed as protruding pins to the outside.
- the actuating members 35 each have two laterally inclined to the longitudinal central axis guide surfaces 35a and 35b, on their upper sides is a single, again obliquely inclined to the longitudinal central axis guide surface 36 is provided.
- 9a and 9b eight actuating members 35 are arranged distributed over the circumference of the second holding member 2, which - in contrast to the guide and locking parts 15, 20 of the first holding element - not directly below the side parts 31 and 32 of the locking members 30, but instead slightly offset thereto are.
- the second holding elements 2 is divided into two areas 3 and 4, wherein the locking parts 30 are arranged on the first region 3 and the actuating members 35 on the second region 4.
- Both regions 3 and 4 are connected to one another via a connection region 6, wherein this connection region 6 is designed such that a relative movement of the two regions 3 and 4 in a plane perpendicular to the axial direction is made possible. This can be achieved, for example, by a corresponding shaping for the connection region 6.
- connection region 6 a flexible material use.
- the second holding element 2 is designed in one piece, which can be achieved, for example, that this is produced in a so-called multi-component injection molding process, in which case a somewhat more flexible material is selected for the formation of the transition region 6.
- FIGS. 10a-h or 11a-h show the individual phases of the assignment of the different parts to each other during the process of locking, while the FIGS. 11a-h show the individual phases when releasing the locking.
- the dimensions of the holding elements 1 and 2 and the guide, actuating and locking parts 15, 20, 30 and 35 is selected such that the cavity 12 can completely accommodate the second holding member 2, however, seen in cross section there is an overlap of the guiding and locking parts 15, 20 projecting towards the inside with the latching and actuating parts 30, 35 projecting outwards. This allows the various elements to interact as described below.
- FIG. 10a shows the arrangement of the latching and guide parts 15, 20 of the first holding element 1 with respect to the latching and actuating parts 30, 35 of the second holding element 2 in an initial stage of the latching. Shown is a state in which the second retaining element 2 has already been introduced so far into the first retaining element 1, that the actuating parts 35 come with their lower ends in abutment against the guide members 20.
- the corresponding alignment of the actuating members 35 on the guide members 20 is achieved in that the gap between the locking members 15 of the first support member 1 is dimensioned such that the locking members 30 of the second support member 2 are guided in a defined arrangement by these clearances. This has the consequence that the guide surfaces 20a and 35a of the guide and operating parts 20, 35 come into abutment against each other.
- a locking of the two holding elements 1 and 2 or a release of the latch can always be achieved by the same operation, namely a nesting of the two parts and a subsequent pulling apart.
- Both the latching and the release of the latching thus take place in the context of a snap-rotary movement, which brings a simplification in the handling of the device according to the invention.
- Of particular importance here is that only an axial actuation of the two holding elements is required, so that the latching or releasing the latch can also be carried out automatically or mechanically.
- a particular advantage of the device according to the invention consists in the fact that the device consists exclusively of two elements, which must be moved to each other. This is made possible by the above-described flexible arrangement of the actuating and locking parts of the second holding element to each other, which allows the required relative to the locking and releasing the locking relative movement of the various elements to each other.
- an actuation of only two components in an automated manner is again significantly easier to implement than was possible in the prior art in which three components were to be handled.
- the production of the entire device is simplified by reducing the number of components to be manufactured.
- FIG. 13 An alternative embodiment of a device according to the invention is finally in FIG. 13 shown.
- the first holding element 101 on its underside a hook 102, which can be used for example for hanging several cords.
- This hook 102 can optionally be opened or closed, so that, for example, can be done easily hooking additional harness cords.
- the holding elements 2 and 101 are again constructed in the manner already explained above. In particular, these in turn have the specially designed guide, actuating and locking parts, wherein the actuating and locking parts of the second holding element are arranged in two different areas, which are connected to each other in a flexible manner.
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum lösbaren Verbinden von Schnüren, welche ein hülsenartiges erstes Halteelement für eine erste Schnur sowie ein bolzenartiges zweites Halteelement für eine zweite Schnur aufweist, wobei das zweite Halteelement in das erste Halteelement einführbar und sowohl zum Verbinden als auch zum Lösen der beiden Halteelemente in einer Axialrichtung bewegbar ist.The present invention relates to a device for releasably connecting strings, which has a sleeve-like first retaining element for a first string and a bolt-like second retaining element for a second string, wherein the second retaining element insertable into the first retaining element and both for connecting and for releasing the two holding elements in an axial direction is movable.
Eine gattungsgemäß Vorrichtung zum lösbaren Verbinden von Schnüren ist beispielsweise aus der
Die bekannte Lösung weist hierzu verschiedene Betätigungs- und Rastmittel auf, welche in Zusammenwirkung mit mehreren Führungsmitteln in einer Anschlagsposition des zweiten Halteelements zum Verbinden bzw. Lösen eine Relativbewegung des ersten und zweiten Halteelements in einer Ebene senkrecht zur Axialrichtung hervorrufen. Am Ende des Zusammendrück-Vorgangs beider Elemente wird somit eine Relativverdrehung der beiden Halteelemente um die Längsachse durchgeführt, durch welche die Verrastung zwischen beiden Halteelementen eingeleitet bzw. wieder gelöst wird. Durch diese besondere Maßnahme ist eine verhältnismäßig einfache Handhabung der Verbindungsvorrichtung gewährleistet, die es insbesondere ermöglicht, das Verbinden bzw. Lösen von Schnüren auch automatisiert vornehmen zu lassen.For this purpose, the known solution has various actuating and latching means which, in cooperation with a plurality of guide means in a stop position of the second holding element for connecting or releasing, cause a relative movement of the first and second holding elements in a plane perpendicular to the axial direction. At the end of the compression process of both elements thus a relative rotation of the two holding elements is performed about the longitudinal axis, by which the locking between the two holding elements is initiated or released again. By this particular measure a relatively simple handling of the connecting device is ensured, which in particular makes it possible to make the connection or release of strings also automated.
Ein Nachteil der aus dem Stand der Technik bekannten Vorrichtung zum lösbaren Verbinden von Schnüren besteht allerdings darin, dass die einzelnen Elemente der Vorrichtung verhältnismäßig komplex aufgebaut sind. Insbesondere ist neben dem ersten Halteelement und dem zweiten Halteelement noch ein drittes Element in Form eines so genannten Verschiebeteils vorgesehen, welches in besonderer Weise mit den beiden Halteelementen zusammenwirkt, um die angestrebte Relativbewegung, die zum Verrasten bzw. Lösen der Verrastung erforderlich ist, einzuleiten. Durch das Erfordernis eines dritten Bauteils wird allerdings die Vorrichtung relativ komplex und damit kostenintensiv in ihrer Herstellung. Darüber hinaus wird die Handhabung der Vorrichtung erschwert, je mehr Bauteile diese aufweist.A disadvantage of the known from the prior art device for releasably connecting strings, however, is that the individual elements of the Device are constructed relatively complex. In particular, in addition to the first holding element and the second holding element, a third element in the form of a so-called sliding part is provided, which cooperates in a special way with the two holding elements to initiate the desired relative movement, which is required for locking or releasing the locking. Due to the requirement of a third component, however, the device is relatively complex and thus costly in their production. In addition, the handling of the device is difficult, the more components it has.
Der vorliegenden Erfindung liegt dementsprechend die Aufgabe zu Grunde, eine neuartige bzw. verbesserte Vorrichtung zum lösbaren Verbinden von Schnüren anzugeben, bei welcher die im Zusammenhang mit dem Stand der Technik beschriebenen Nachteile bzw. Einschränkungen vermieden werden.The present invention is therefore based on the object to provide a novel or improved device for releasably connecting strings, in which the disadvantages or limitations described in connection with the prior art are avoided.
Die Aufgabe wird durch eine Vorrichtung zum lösbaren Verbinden von Schnüren, welche die Merkmale des Anspruches 1 aufweist, gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The object is achieved by a device for releasably connecting strings, which has the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.
Die erfindungsgemäße Lösung beruht auf einer speziellen Ausgestaltung des bolzenartigen zweiten Halteelements. Erfindungsgemäß ist vorgesehen, dass dieses als einstückiges Bauteil ausgestaltet ist, welches einen ersten, sog. Betätigungsteile aufweisenden, und einen zweiten, sog. Rastteile aufweisenden Bereich aufweist, wobei beide Bereiche miteinander verbunden sind. Durch diese erfindungsgemäße Ausgestaltung des zweiten Halteelements besteht nunmehr die Möglichkeit, auf das beim Stand der Technik noch erforderliche Verschiebeteil zu verzichten. Statt dessen sind sämtliche Elemente bzw. Komponenten, welche die besondere Bewegung zwischen dem ersten und dem zweiten Halteelement untereinander zum Verrasten bzw. Lösen der Verrastung bewirken, an einem der beiden Halteelemente angeordnet. Die erfindungsgemäße Vorrichtung zum lösbaren Verbinden von Schnüren besteht dementsprechend ausschließlich aus zwei getrennten Elementen bzw. Bauteilen, was einerseits Vorteile bei der Herstellung und andererseits Vorteile bei der Handhabung der Vorrichtung mit sich bringt.The solution according to the invention is based on a special embodiment of the bolt-like second holding element. According to the invention it is provided that this is designed as a one-piece component, which has a first, so-called. Actuating parts, and a second, so-called. Detent parts having area, both areas are interconnected. By means of this embodiment of the second retaining element according to the invention, it is now possible to dispense with the sliding part which is still required in the prior art. Instead, all elements or components which effect the particular movement between the first and the second holding element with one another for latching or releasing the latch, are arranged on one of the two holding elements. The inventive device for releasably connecting strings accordingly consists exclusively of two separate elements or components, which on the one hand brings advantages in the production and on the other hand advantages in the handling of the device.
Erfindungsgemäß wird also eine Vorrichtung zum lösbaren Verbinden von Schnüren vorgeschlagen, welche ein hülsenartiges erstes Halteelement für eine erste Schnur und ein bolzenartiges zweites Halteelement für eine zweite Schnur aufweist, wobei das zweite Halteelement in das erste Halteelement einführbar und zum Verbinden und Lösen der beiden Halteelemente in eine Axialrichtung bewegbar ist und wobei das zweite Halteelement Betätigungs- und Rastteile aufweist, welche in Zusammenwirkung mit an dem ersten Halteelement befindlichen Führungs- und Rastteilen in einer Anschlagsposition des zweiten Halteelements zum Verbinden bzw. Lösen eine Relativbewegung des ersten und des zweiten Halteelements in einer Ebene senkrecht zur Axialrichtung hervorrufen. Erfindungsgemäß ist das zweite Halteelement als ein einstückiges Bauteil mit einem die Rastteile aufweisenden ersten Bereich und einem die Betätigungsteile aufweisenden zweiten Bereich ausgestaltet ist.According to the invention, a device for releasably connecting strings is proposed, which has a sleeve-like first retaining element for a first string and a bolt-like second retaining element for a second string, wherein the second retaining element inserted into the first retaining element and for connecting and detaching the two holding elements in an axial direction is movable and wherein the second holding element actuating and locking parts, which in Collaboration with located on the first holding element guiding and locking parts in a stop position of the second holding element for connecting or releasing cause a relative movement of the first and the second holding element in a plane perpendicular to the axial direction. According to the invention, the second holding element is configured as a one-piece component with a first region having the latching parts and a second region having the actuating parts.
Gemäß einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung sind die beiden Bereiche des zweiten Halteelements in Axialrichtung gesehen hintereinander angeordnet. Um die gewünschte Relativdrehung des zweiten Halteelements gegenüber dem ersten Halteelement durchführen zu können, ist dabei gemäß einem besonders bevorzugten Ausführungsbeispiel vorgesehen, dass beide Bereiche des zweiten Halteelements flexibel miteinander verbunden sind. Hierzu sind die beiden Bereiche über einen Verbindungsbereich miteinander verbunden, welcher derart ausgestaltet ist, dass eine Relativbewegung der beiden Bereiche in der Ebene senkrecht zur Axialrichtung ermöglicht ist. Diese besondere Art der Ausgestaltung des zweiten Halteelements gestattet es, die bereits aus dem Stand der Technik bekannten Vorgänge zum Verrasten bzw. Lösen der Verrastung durchzuführen. Dadurch, dass nunmehr eine flexible Verbindung zwischen den beiden Bereichen des zweiten Halteelements geschaffen wird, können die Einrast- und Ausrast-Bewegungen die später noch beschrieben Schnapp-Drehbewegungen vollzogen werden, ohne dass der Einsatz eines dritten Bauteils erforderlich wäre. Das zweite Halteelement kann dabei trotz allem einstückig ausgestaltet werden, da jederzeit die Möglichkeit besteht, den Verbindungsbereich in entsprechender Weise auszugestalten, dass die flexible Verbindung sichergestellt ist. Hierzu könnte beispielsweise der Verbindungsbereich in geeigneter Weise dimensioniert werden. Eine andere Möglichkeit würde darin bestehen, für diesen Verbindungsbereich ein spezielles Material zu verwenden, welches die erforderliche Flexibilität aufweist. Beispielsweise könnte in diesem Fall des zweite Halteelement in einem Mehrkomponenten-Spritzgussverfahren hergestellt werden. In jedem Fall weist die erfindungsgemäße Lösung deutliche Vorteile gegenüber bislang eingesetzten Vorrichtungen auf, da lediglich zwei unterschiedliche Bauteile hergestellt und gehandhabt werden müssen, was kostengünstiger und einfacher ist.According to a particularly preferred embodiment of the present invention, the two areas of the second holding element are arranged one behind the other as seen in the axial direction. In order to be able to perform the desired relative rotation of the second holding element relative to the first holding element, it is provided according to a particularly preferred embodiment that both areas of the second holding element are flexibly connected to each other. For this purpose, the two regions are connected to each other via a connection region, which is designed such that a relative movement of the two regions in the plane perpendicular to the axial direction is made possible. This particular type of embodiment of the second holding element makes it possible to perform the already known from the prior art operations for locking or releasing the locking. The fact that now a flexible connection between the two areas of the second holding element is created, the latching and Ausrast movements described later snap-rotary movements can be completed without the use of a third component would be required. The second holding element can be configured in one piece despite everything, since there is always the possibility to design the connection area in a corresponding manner, that the flexible connection is ensured. For this purpose, for example, the connection area could be suitably dimensioned. Another possibility would be to use a special material for this connection area which has the required flexibility. For example, in this case, the second holding element could be produced in a multi-component injection molding process. In any case, the solution of the invention has significant advantages over previously used devices, since only two different components must be manufactured and handled, which is cheaper and easier.
Weitere abhängige Ansprüche betreffen spezielle Ausgestaltungen der unterschiedlichen Betätigungs-, Rast- und Führungsteile. Diese können insbesondere speziell ausgestaltete Anlaufschrägen oder -flächen aufweisen, um die erforderlichen Bewegungen zwischen den beiden Halteelementen einzuleiten.Further dependent claims relate to specific embodiments of the different actuating, latching and guide parts. These can in particular have specially designed run-on slopes or surfaces in order to initiate the required movements between the two holding elements.
Eine andere Weiterbildung der vorliegenden Erfindung betrifft eine Maßnahme, durch welche die axiale Zentrierung des zweiten Halteelements beim Einführen in das erste Halteelement sichergestellt ist. Hierzu weist das erste Halteelement eine bodenseitige Vertiefung auf, welche mit einer konischen Spitze am vorderen Ende des zweiten Halteelements zusammenwirkt. Auf diese Weise ist sichergestellt, dass grundsätzlich eine geeignete Ausrichtung der verschiedenen Rast-, Betätigungs- und Führungsteile vorliegt. Damit ist gewährleistet, dass die verschiedenen Elemente auch wie vorgesehen zusammenwirken.Another development of the present invention relates to a measure by which the axial centering of the second holding element is ensured during insertion into the first holding element. For this purpose, the first holding element has a bottom-side depression, which cooperates with a conical tip at the front end of the second holding element. In this way, it is ensured that, in principle, there is a suitable alignment of the various latching, actuating and guide parts. This ensures that the various elements also interact as intended.

Das Verrasten und Lösen der beiden Halteelemente 1, 2 wird durch an dem zweiten Halteelement 2 befindliche Rastteile 30 und Betätigungsteile 35 bewirkt, welche in besonderer Weise mit den Führungsteilen 20 und Rastteilen 15 des ersten Halteelements 1 zusammenwirken. Die besondere Ausgestaltung der Rastteile 30 und Betätigungsteile 35 kann dabei insbesondere den Darstellungen der
Gemäß diesen Darstellungen sind die Rastteile 30 jeweils durch ein kürzeres Seitenteil 31 sowie ein längeres Seitenteil 32 gebildet, welche an ihrer Unterseite über eine schräg zur Axialrichtung des Halteelements 2 verlaufende Führungsfläche 33 miteinander verbunden sind. Zwischen beiden Seitenteilen 31 und 32, die an ihren oberen Enden jeweils parallel zur Führungsfläche 33 verlaufende Abschrägungen 31a und 32a aufweisen, wird damit eine zur Oberseite hin offene Rastausnehmung 30a gebildet. Wie
Unterhalb der Rastteile 30 sind Betätigungsteile 35 angeordnet, die wiederum als zur Außenseite vorstehende Stifte ausgestaltet sind. An ihren Unterseiten weisen die Betätigungsteile 35 jeweils zwei seitlich zur Längsmittelachse geneigte Führungsflächen 35a und 35b auf, an ihren Oberseiten ist eine einzelne, wiederum schräg zur Längsmittelachse geneigte Führungsfläche 36 vorgesehen. Entsprechend den Darstellungen der
Eine besonders wesentliche Eigenschaft des zweiten Halteelements 2 ist allerdings, dass die Anordnung der Rastteile 30 und Betätigungsteile 35 zueinander nicht vollkommen starr ist, sondern stattdessen eine zumindest geringfügige Flexibilität aufweist. Wie der Darstellung in
Das Zusammenwirken der Führungs-, Betätigungs- und Rastteile 15, 20, 30 und 35 zum Verbinden der beiden Halteelemente 1 und 2 miteinander bzw. zum Lösen der Verbindung kann den
Nachfolgend soll zunächst anhand der
Werden nunmehr die beiden Halteelemente 1, 2 weiter gegeneinander gedrückt, wie dies durch die Pfeile symbolisch dargestellt ist, so führt dies dazu, dass aufgrund der Führungsflächen 20a und 35a die Betätigungsteile 35 zur Seite (in der Darstellung nach links) abgelenkt werden, wie dies der Darstellung in
Erst wenn das zweite Halteelement 2 so weit herabgedrückt wurde, dass sich die Rastteile 30 vollständig unterhalb der Rastteile 15 befinden, wie dies in
Zu diesem Zeitpunkt befinden sich die beiden Halteelemente 1 und 2 in einer Anschlagsposition und werden nun nicht mehr ineinander gedrückt. Stattdessen werden sie nunmehr kurzfristig auseinander gezogen. Hierbei geraten nunmehr zunächst die oberen Führungsflächen 31a der Seitenteile 31 der Rastteile 30 in Anlage gegen die unteren Führungsflächen 17 der Rastteile 15, wie dies in
Zum Lösen der Verrastung werden im Wesentlichen die gleichen Bewegungen vollzogen. Zunächst werden gemäß den Darstellungen 11a - 11d die beiden Halteelemente 1 und 2 bis zur Anschlagsposition ineinander geschoben, wobei aufgrund der Ausrichtung der Rast-, Betätigungs- und Führungsteile 15, 20, 30, 35 wiederum zunächst die Betätigungsteile 35 seitlich abgelenkt werden (
Werden nunmehr die beiden Halteelemente 1 und 2 auseinandergezogen, so werden aufgrund der Führungsflächen 17 und 32a der Rastteile 15 und 30 die Rastteile 30 derart abgelenkt, dass sie vollständig aus dem Eingriff der Rastteile 15 gelangen und in die Zwischenräume zwischen den Rastteilen 15 überführt werden. Diese seitliche Ablenkung wird zu einem späteren Zeitpunkt auch von den Betätigungsteilen 35 nachgeholt, bis schließlich die Anordnung gemäß
Insgesamt kann somit ein Verrasten der beiden Halteelemente 1 und 2 bzw. ein Lösen der Verrastung immer durch die gleichartige Betätigung erzielt werden, nämlich ein Ineinanderschieben der beiden Teile und ein anschließendes Auseinanderziehen. Sowohl das Verrasten als auch das Lösen der Verrastung erfolgen damit im Rahmen einer Schnapp-Drehbewegung, was eine Vereinfachung in der Handhabung der erfindungsgemäßen Vorrichtung mit sich bringt. Von besonderer Bedeutung hierbei ist auch, dass lediglich eine axiale Betätigung der beiden Halteelemente erforderlich ist, so dass das Verrasten bzw. das Lösen der Verrastung auch automatisiert bzw. maschinell durchgeführt werden kann.Overall, therefore, a locking of the two holding elements 1 and 2 or a release of the latch can always be achieved by the same operation, namely a nesting of the two parts and a subsequent pulling apart. Both the latching and the release of the latching thus take place in the context of a snap-rotary movement, which brings a simplification in the handling of the device according to the invention. Of particular importance here is that only an axial actuation of the two holding elements is required, so that the latching or releasing the latch can also be carried out automatically or mechanically.
Ein besonderer Vorteil der erfindungsgemäßen Vorrichtung besteht dabei darin, dass die Vorrichtung ausschließlich aus zwei Elementen besteht, welche zueinander bewegt werden müssen. Dies wird durch die zuvor beschriebene flexible Anordnung der Betätigungs- und Rastteile des zweiten Halteelements zueinander ermöglicht, welche die für das Verrasten und Lösen der Verrastung erforderliche Relativbewegung der verschiedenen Elemente zueinander ermöglicht. Die Tatsache, dass die Vorrichtung insgesamt gesehen aus lediglich zwei getrennten Elementen besteht, bringt dabei zusätzliche Vorteile bei der Handhabung der Vorrichtung mit sich. Insbesondere ist eine Betätigung von lediglich zwei Bauteilen in automatisierter Weise nochmals deutlich einfacher zu realisieren, als dies beim Stand der Technik, bei dem drei Bauteile zu handhaben waren, möglich war. Auch die Herstellung der gesamten Vorrichtung wird durch die Reduzierung der Anzahl der herzustellenden Bauteile vereinfacht.A particular advantage of the device according to the invention consists in the fact that the device consists exclusively of two elements, which must be moved to each other. This is made possible by the above-described flexible arrangement of the actuating and locking parts of the second holding element to each other, which allows the required relative to the locking and releasing the locking relative movement of the various elements to each other. The fact that the device as a whole consists of only two separate elements, brings with it additional advantages in the handling of the device with it. In particular, an actuation of only two components in an automated manner is again significantly easier to implement than was possible in the prior art in which three components were to be handled. The production of the entire device is simplified by reducing the number of components to be manufactured.
