Definitions
- the invention relates to a guide rail for a linear bearing with a plurality of through openings arranged one behind the other in the longitudinal direction of the rail and extending from the top of the rail for receiving fastening elements, with a longitudinal groove open to the top of the rail and extending over the length of the guide rail, and with a longitudinal groove and the through openings outwardly covering closure body, which is partially or completely inserted into the longitudinal groove, wherein it is pressed into the guide rail under elastic deformation and is fastened there due to its restoring spring force.
- Guide rails are used on machine tools and must be replaced as wear parts from time to time. Therefore, they are often attached to the machine frame with screws.
- a cover band is used to close the bores for the screws as a closure body, which covers the entire width of the guide rail when pressed into the longitudinal groove of the guide rail bulges. Due to its return spring force, the masking tape claws into the side surfaces of the longitudinal groove, so that it is held in the groove along two contact lines. The space of the through openings is closed to the outside along these lines of contact.
- the cover band does not have flat sealing surfaces for the front seals of a guide carriage which can be moved along the guide rail, which can have a disadvantageous effect on the seal.
- a guide rail is known in which a cover plate, which (forming a flat Dichtf kiee, rests with the angled edge portions within a longitudinal groove of the guide rail on the inclined side surfaces. This results in an arrangement of the shroud relative to the guide rail as with a dovetail guide, but when installing the cover plate, it must be inserted from one end into the guide rail in the longitudinal direction of the rail.
- the published patent application DE 195 24 810 A1 shows and describes an arrangement for closing bores in a guide rail, in which two projecting resilient retaining strips for attachment are formed on a cover band used as a closure body and rest against the edges within a longitudinal groove of the guide rail , These are located on two inclined webs, which are formed by milling out the guide rail. The retaining strips can be pushed into the resulting dovetail profile of the longitudinal groove when installing the cover tape. As a result of the two inclined webs, however, there is a disadvantageous production of the guide rail.
- the invention is based on the object of providing a simply constructed guide rail with a flat sealing surface for the front seals of a guide carriage, which enables the closure body to be mounted easily.
- the closure body consists of an outer cover band and in relation to the guide rail an inner clamping band fastened thereon is formed, which has clamping regions and spacers arranged between the cover band and the clamping regions.
- the clamping band deforms when the closure body is pressed in and claws firmly in the longitudinal groove.
- the effect of the resulting deformation is compensated for by the spacer and is therefore not passed on to the masking tape. Therefore, the masking tape does not bulge.
- the clamping band can be made in one piece with the clamping areas and the spacers. Spacers which extend continuously in the longitudinal direction and spacers in several individual sections can be formed on the clamping band and connected to the cover band. The fact that a plurality of individual spacers are formed one behind the other on a clamping band means that it can be rolled.
- the masking tape and the clamping tape can be glued or welded together, for example.
- the guide rail can have two insertion grooves running in the longitudinal direction, each adjoining the longitudinal groove, into which the clamping areas of the clamping band are pressed.
- the longitudinal groove in the guide rail can be designed such that it has shoulders on its long sides.
- the masking tape can be arranged on the guide rail with edge regions lying on the top of the rail. But it is also possible that Insert the closure body into the guide rail so that the cover strip forms a common, flat outer surface with the top of the rail.
- Embodiments of the invention are shown in the drawing in comparison with a previously known guide rail, which is described in more detail below. Show it:
- Figure 1 is an end view of a closure body for a guide rail according to the invention
- Figure 2 shows the cross section of a guide rail, in which the closure body according to Figure 1 is partially inserted;
- Figure 3 shows a further closure body in an end view
- FIG. 4 shows a representation corresponding to FIG. 2 with the further closure body
- Figure 5 shows the cross section of a guide rail, in which a closure body is fully inserted in a third embodiment
- FIG. 6 shows a perspective view of the clamping band of the closure body according to FIG. 5;
- FIG. 7 shows the cross section of a guide rail into which a closure body is completely inserted in a fourth embodiment
- Figure 8 is a perspective view of a longitudinal portion of a previously known guide rail, the longitudinal groove of which is rectangular in cross section, with an end face cut in the region of a through opening;
- FIG. 9 shows an enlarged section of the end face according to encirclement IX of FIG. 8;
- FIG. 10 shows a cross section through the guide rail according to FIG. 8.
- a cover band 1 which consists of a resilient band material, for example a steel sheet, is inserted in a longitudinal groove 2 of the guide rail 5.
- the longitudinal groove starts from the upper side 3 of the rail and has a somewhat smaller width than the cover strip 1. This therefore had to bulge out towards the guide rail 5 when it was pressed into the longitudinal groove.
- a cover band 7 shown in FIGS. 1 and 2 for a guide rail 5 according to the invention is fixedly connected to a gill band 8, which lies on the surface of the cover band 7 which faces the interior of the guide rail 5.
- This clamping band 8 is provided at its longitudinal ends with two bent spacers 9, which in turn merge into clamping regions 10, namely clamping legs 10, which are bent towards the inside of the guide rail 5.
- the guide rail 5 is provided on its upper side with a central longitudinal groove 11 which serves to hold the clamping band 8.
- two insertion grooves 12 are additionally machined into the guide rail 5, which correspond to the position of the clamping legs 10 and the spacers 9 and start from the longitudinal groove 11.
- the clamping legs 10 have a slightly larger length. They therefore bend resiliently when the cover strip 7 with the clamping strip 8 is pressed into the longitudinal groove 11 and the insertion grooves 12 of the guide rail 5.
- the clamping legs 10 grip the guide rail 5 and thus hold the cover band 7, which rests with its edge regions on the top side 3 of the rail, in its position.
- the spacers 9 on the clamping band 8 are bent at right angles. However, they can also be set slightly laterally, for example forming an angle with the region of the clamping band 8 which is in contact with the cover band 7 and deviates by 5 ° from the right angle. This makes it easier to assemble.
- the embodiment of the closure body shown in FIGS. 3 and 4 differs from this embodiment in that the clamping band 13 fastened to the cover band 7, with its spacers 9 bent at right angles, has clamping legs 14 which are bent at right angles to the outside of the guide rail 5.
- the longitudinal groove 15 of the guide rail 5 is made deeper so that the spacers 9 are not laterally guided and can dodge to the inside of the guide rail 5 if the cover band 7 with the clamping band 13 is pressed into the longitudinal groove 15 until the clamping band 7 on the top of the rail 3 is present.
- the clamping limbs 14 grip the outer boundary walls of the longitudinal groove 15 of the guide rail 5.
- a clamping band 16 with clamping legs 17 in the form of a sheet metal strip is designed for a guide rail 5 according to the invention, on which spacers 18 arranged one after the other at intervals along the longitudinal center line are formed. These are attached to the inner surface of the cover strip with respect to the guide rail 5. With its outer surface, the cover band 7 forms, together with the top side of the rail 3, a flat contact surface for the front seals of the guide carriage to be used.
- the longitudinal groove 19 of the guide rail 5 is designed with steps. Thus, it has an area with a slightly smaller width than the width of the clamping band 16, so that the clamping legs 17 grip the guide rail 5 here. Below that are paragraphs 20 which limit the depth of insertion of the closure body. Over the area with the shoulders 20, the longitudinal groove 19 has an area of even greater width, in which the cover band 7 is accommodated.
- FIG. 7 An embodiment similar to this embodiment is shown in FIG. 7.
- the closure body inserted into the longitudinal groove 19 of the guide rail 5 differs only in the embodiment of its clamping band 21, which is designed with its clamping legs 22 and at least one spacer 23 as a one-piece bent sheet metal part.

Führungsschiene für ein Lineariager Guide rail for a linear bearing
Beschreibungdescription
Gebiet der ErfindungField of the Invention
Die Erfindung betrifft eine Führungsschiene für ein Linearlager mit mehreren in Schienenlängsrichtung in Abständen hintereinander angeordneten, von der Schienenoberseite ausgehenden Durchgangsöffnungen für die Aufnahme von Befestigungselementen, mit einer zur Schienenoberseite offenen, sich über die Länge der Führungsschiene erstreckenden Längsnut und mit einem die Längsnut und die Durchgangsöffnungen nach außen abdeckenden Verschlußkörper, welcher teilweise oder vollständig in die Längsnut eingesetzt ist, wobei er unter elastischer Verformung in die Führungsschiene eingedrückt und dort aufgrund seiner Rückstellfederkraft befestigt ist.The invention relates to a guide rail for a linear bearing with a plurality of through openings arranged one behind the other in the longitudinal direction of the rail and extending from the top of the rail for receiving fastening elements, with a longitudinal groove open to the top of the rail and extending over the length of the guide rail, and with a longitudinal groove and the through openings outwardly covering closure body, which is partially or completely inserted into the longitudinal groove, wherein it is pressed into the guide rail under elastic deformation and is fastened there due to its restoring spring force.
Hintergrund der ErfindungBackground of the Invention
Führungsschienen werden an Werkzeugmaschinen verwendet und müssen als Verschleißteile von Zeit zu Zeit ausgewechselt werden. Daher sind sie häufig mit Schrauben am Maschinengestell befestigt. Bei einer aus der Offenlegungs- schrift DE 196 15 075 A1 vorbekannten Führungsschiene der eingangs genannten Art wird zum Verschließen der Bohrungen für die Schrauben als Verschlußkörper ein Abdeckband verwendet, welches sich beim Eindrücken in die Längsnut der Führungsschiene auf seiner gesamten Breite zur Führungsschie- ne hin auswölbt. Durch seine Rückstellfederkraft krallt sich das Abdeckband in die Seitenflächen der Längsnut, so dass es dort längs zweier Berührungslinien in der Nut gehalten wird. Längs dieser Berührungslinien ist der Raum der Durchgangsöffnungen nach außen verschlossen. Infolge seiner Auswölbung weist das Abdeckband ebene Dichtflächen für die Frontdichtungen eines längs der Führungsschiene verfahrbaren Führungswagens nicht auf, was sich auf die Abdichtung nachteilig auswirken kann.Guide rails are used on machine tools and must be replaced as wear parts from time to time. Therefore, they are often attached to the machine frame with screws. In the case of a guide rail of the type mentioned at the beginning of the published patent application DE 196 15 075 A1, a cover band is used to close the bores for the screws as a closure body, which covers the entire width of the guide rail when pressed into the longitudinal groove of the guide rail bulges. Due to its return spring force, the masking tape claws into the side surfaces of the longitudinal groove, so that it is held in the groove along two contact lines. The space of the through openings is closed to the outside along these lines of contact. As a result of its bulge the cover band does not have flat sealing surfaces for the front seals of a guide carriage which can be moved along the guide rail, which can have a disadvantageous effect on the seal.
Aus dem Gebrauchsmuster DE 94 20 428 U1 ist eine Führungsschiene bekannt, bei der ein Abdeckblech, welches eine ebene Dichtf(äche bildet,, mit abgewinkelten Randbereichen innerhalb einer Längsnut der Führungsschiene an geneigten Seitenflächen anliegt. Dabei ergibt sich eine Anordnung des Abdeckblechs gegenüber der Führungsschiene wie bei einer Schwalben- schwanzführung. Bei der Montage des Abdeckblechs muss dieses allerdings von einer Stirnseite aus in die Führungsschiene in Schienenlängsrichtung eingeschoben werden.From the utility model DE 94 20 428 U1, a guide rail is known in which a cover plate, which (forming a flat Dichtf äche, rests with the angled edge portions within a longitudinal groove of the guide rail on the inclined side surfaces. This results in an arrangement of the shroud relative to the guide rail as with a dovetail guide, but when installing the cover plate, it must be inserted from one end into the guide rail in the longitudinal direction of the rail.
Die Offenlegungsschrift DE 195 24 810 A1 zeigt und beschreibt eine Anord- nung zum Verschließen von Bohrungen in einer Führungsschiene, bei welcher an einem als Verschlußkörper verwendeten Abdeckband zwei abstehende federnde Halteleisten für die Befestigung angeformt sind, die innerhalb einer Längsnut der Führungsschiene an den Rändern anliegen. Diese befinden sich an zwei schräggestellten Stegen, die durch Ausfräsen der Führungsschiene gebildet sind. In das so entstandene Schwalbenschwanzprofil der Längsnut können die Halteleisten bei der Montage des Abdeckbandes eingeschoben werden. Infolge der beiden schräggestellten Stege ergibt sich hier jedoch in nachteiliger Weise eine aufwendige Herstellung der Führungsschiene.The published patent application DE 195 24 810 A1 shows and describes an arrangement for closing bores in a guide rail, in which two projecting resilient retaining strips for attachment are formed on a cover band used as a closure body and rest against the edges within a longitudinal groove of the guide rail , These are located on two inclined webs, which are formed by milling out the guide rail. The retaining strips can be pushed into the resulting dovetail profile of the longitudinal groove when installing the cover tape. As a result of the two inclined webs, however, there is a disadvantageous production of the guide rail.
Zusammenfassung der ErfindungSummary of the invention
Der Erfindung liegt die Aufgabe zu Grunde, eine einfach aufgebaute Führungsschiene mit ebener Abdichtfläche für die Frontdichtungen eines Führungswagens zu schaffen, die eine leicht durchführbare Montage des Verschlußkörpers ermöglicht.The invention is based on the object of providing a simply constructed guide rail with a flat sealing surface for the front seals of a guide carriage, which enables the closure body to be mounted easily.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Verschlußkörper aus einem in Bezug auf die Führungsschiene äußeren Abdeckband und einem daran befestigten inneren Klemmband gebildet ist, welches Klemmbereiche und zwischen dem Abdeckband und den Klemmbereichen angeordnete Distanzhalter aufweist. Auf diese Weise ergibt sich ein Klemm-Mechanismus, bei welchem eine gewölbte Oberfläche des in die Führungsschiene eingesetz- ten Abdeckbandes und eine dadurch bedingte Rinne im Dichtungsbereich nicht auftritt. An Führungswagen vorhandene Dichtungssysteme können daher bei der Führungsschiene mit dem erfindungsgemäßen Verschlußkörper verwendet werden, wobei sich eine einfache Dichtungsgeometrie ergibt.According to the invention, this object is achieved in that the closure body consists of an outer cover band and in relation to the guide rail an inner clamping band fastened thereon is formed, which has clamping regions and spacers arranged between the cover band and the clamping regions. This results in a clamping mechanism in which a curved surface of the cover strip inserted into the guide rail and a resulting groove in the sealing area do not occur. Sealing systems on guide carriages can therefore be used in the guide rail with the closure body according to the invention, resulting in a simple sealing geometry.
Aufgrund eines Übermaßes des Verschlußkörpers im Klemmbereich gegenüber der Nutbreite der Führungsschiene verformt sich das Klemmband beim Eindrücken des Verschlußkörpers und krallt sich in der Längsnut fest. Die Wirkung der dabei entstehenden Verformung wird von dem Distanzhalter ausgeglichen und somit nicht an das Abdeckband weitergeleitet. Daher erfolgt eine Auswöl- bung des Abdeckbandes nicht.Due to an excess of the closure body in the clamping area compared to the groove width of the guide rail, the clamping band deforms when the closure body is pressed in and claws firmly in the longitudinal groove. The effect of the resulting deformation is compensated for by the spacer and is therefore not passed on to the masking tape. Therefore, the masking tape does not bulge.
Das Klemmband kann mit den Klemmbereichen und den Distanzhaltern einstückig ausgeführt sein. An dem Klemmband können sowohl in Längsrichtung sich kontinuierlich erstreckende Distanzhalter als auch Distanzhalter in mehre- ren einzelnen Abschnitten ausgebildet und mit dem Abdeckband verbunden sein. Dadurch, dass an einem Klemmband mehrere einzelne Distanzhalter in Abständen hintereinander ausgebildet sind, wird dieses rollbar. Das Abdeckband und das Klemmband können beispielsweise miteinander verklebt oder verschweißt sein.The clamping band can be made in one piece with the clamping areas and the spacers. Spacers which extend continuously in the longitudinal direction and spacers in several individual sections can be formed on the clamping band and connected to the cover band. The fact that a plurality of individual spacers are formed one behind the other on a clamping band means that it can be rolled. The masking tape and the clamping tape can be glued or welded together, for example.
Die Führungsschiene kann zwei in Längsrichtung verlaufende, sich jeweils an der Längsnut anschließende Einstecknuten aufweisen, in welche die Klemmbereiche des Klemmbandes eingedrückt sind. Für die Begrenzung der Eindrücktiefe der Klemmbereiche kann die Längsnut in der Führungsschiene so ausge- bildet sein, dass sie an ihren Längsseiten Absätze aufweist.The guide rail can have two insertion grooves running in the longitudinal direction, each adjoining the longitudinal groove, into which the clamping areas of the clamping band are pressed. To limit the depth of indentation of the clamping areas, the longitudinal groove in the guide rail can be designed such that it has shoulders on its long sides.
Das Abdeckband kann mit Randbereichen auf der Schienenoberseite aufliegend an der Führungsschiene angeordnet sein. Es ist aber auch möglich, den Verschlußkörper so in die Führungsschiene einzusetzen, dass das Abdeckband mit der Schienenoberseite eine gemeinsame ebene Außenfläche bildet.The masking tape can be arranged on the guide rail with edge regions lying on the top of the rail. But it is also possible that Insert the closure body into the guide rail so that the cover strip forms a common, flat outer surface with the top of the rail.

Ausführliche Beschreibung der ZeichnungDetailed description of the drawing
Bei einer vorbekannten, in den Figuren 8 bis 10 dargestellten Führungsschiene ist ein Abdeckband 1 , welches aus einem federnden Bandmaterial, beispiels- weise einem Stahlblech besteht, in einer Längsnut 2 der Führungsschiene 5 eingesetzt. Die Längsnut geht von der Schienenoberseite 3 aus und hat eine etwas geringere Breite als das Abdeckband 1. Dieses musste sich daher, als es in die Längsnut eingedrückt wurde, zur Führungsschiene 5 hin auswölben. Mit dem Abdeckband 1 , dass sich in der Längsnut 2 befindet, werden mehrere in Längsrichtung der Führungsschiene 5 in Abständen hintereinander angeordnete senkrechte Durchgangsöffnungen 4 verschlossen. Diese Öffnungen sind als Stufenbohrungen zur Aufnahme von Befestigungsschrauben ausgebildet.In a previously known guide rail shown in FIGS. 8 to 10, a cover band 1, which consists of a resilient band material, for example a steel sheet, is inserted in a longitudinal groove 2 of the guide rail 5. The longitudinal groove starts from the upper side 3 of the rail and has a somewhat smaller width than the cover strip 1. This therefore had to bulge out towards the guide rail 5 when it was pressed into the longitudinal groove. A plurality of vertical through openings 4, which are arranged one behind the other in the longitudinal direction of the guide rail 5, are closed with the cover strip 1, which is located in the longitudinal groove 2. These openings are designed as stepped bores for receiving fastening screws.
Infolge seiner elastischen Auswölbung tritt in dem Abdeckband 1 eine Rück- stellfederkraft auf, die auf die Seitenflächen der Längsnut 2 einwirkt. Auf diese Weise wird das Abdeckband 1 in der Längsnut 2 der Führungsschiene 5 gehalten. Die Längsnut 2 ist im Querschnitt rechteckig ausgeführt. Sie weist in Figur 10 Absätze 6 auf, so dass die Eindrücktiefe des Abdeckbandes 1 in en- gen Grenzen gehalten wird und zwei weitere Berührungslinien zwischen dem Abdeckband und der Führungsschiene gebildet sind. Ein in den Figuren 1 und 2 dargestelltes Abdeckband 7 für eine erfindungsgemäße Führungsschiene 5 ist mit einem Kiemmband 8 fest verbunden, welches an derjenigen Oberfläche des Abdeckbandes 7 anliegt, die zum Inneren der Führungsschiene 5 weist. Dieses Klemmband 8 ist an seinen Längsenden mit zwei abgebogenen Distanzhaltern 9 versehen, die in wiederum abgebogene und zur Innenseite der Führungsschiene 5 gerichtete Klemmbereiche, nämlich Klemmschenkel 10 übergehen. Die Führungsschiene 5 ist an ihrer Oberseite mit einer mittleren Längsnut 11 versehen, die der Aufnahme des Klemmbandes 8 dient. Für die Distanzhalter 9 und die Klemmschenkel 10 sind in die Füh- rungsschiene 5 zusätzlich zwei Einstecknuten 12 eingearbeitet, die der Lage der Klemmschenkel 10 und der Distanzhalter 9 entsprechen und von der Längsnut 11 ausgehen. Gegenüber der Breite dieser Einstecknuten weisen die Klemmschenkel 10 ein geringfügig größeres Längenmaß auf. Daher verbiegen sie sich federnd, wenn das Abdeckband 7 mit dem Klemmband 8 in die Längs- nut 11 und die Einstecknuten 12 der Führungsschiene 5 eingedrückt wird. Die Klemmschenkel 10 krallen sich auf diese Weise in der Führungsschiene 5 fest und halten damit das Abdeckband 7, welches mit seinen Randbereichen an der Schienenoberseite 3 anliegt, in seiner Lage fest. In Figur 1 sind die Distanzhalter 9 an dem Klemmband 8 rechtwinkelig abgebogen. Sie können aber auch seitlich geringfügig angestellt sein, wobei sie mit dem an dem Abdeckband 7 anliegenden Bereich des Klemmbandes 8 beispielsweise einen Winkel bilden, der um 5° von dem rechten Winkel abweicht. Auf diese Weise lässt sich eine leichtere Montierbarkeit erzielen.As a result of its elastic bulge, a return spring force occurs in the cover band 1, which acts on the side surfaces of the longitudinal groove 2. In this way, the cover tape 1 is held in the longitudinal groove 2 of the guide rail 5. The longitudinal groove 2 is rectangular in cross section. It has paragraphs 6 in FIG. 10, so that the indentation depth of the cover strip 1 is kept within narrow limits and two further lines of contact are formed between the cover strip and the guide rail. A cover band 7 shown in FIGS. 1 and 2 for a guide rail 5 according to the invention is fixedly connected to a gill band 8, which lies on the surface of the cover band 7 which faces the interior of the guide rail 5. This clamping band 8 is provided at its longitudinal ends with two bent spacers 9, which in turn merge into clamping regions 10, namely clamping legs 10, which are bent towards the inside of the guide rail 5. The guide rail 5 is provided on its upper side with a central longitudinal groove 11 which serves to hold the clamping band 8. For the spacers 9 and the clamping legs 10, two insertion grooves 12 are additionally machined into the guide rail 5, which correspond to the position of the clamping legs 10 and the spacers 9 and start from the longitudinal groove 11. Compared to the width of these insertion grooves, the clamping legs 10 have a slightly larger length. They therefore bend resiliently when the cover strip 7 with the clamping strip 8 is pressed into the longitudinal groove 11 and the insertion grooves 12 of the guide rail 5. In this way, the clamping legs 10 grip the guide rail 5 and thus hold the cover band 7, which rests with its edge regions on the top side 3 of the rail, in its position. In Figure 1, the spacers 9 on the clamping band 8 are bent at right angles. However, they can also be set slightly laterally, for example forming an angle with the region of the clamping band 8 which is in contact with the cover band 7 and deviates by 5 ° from the right angle. This makes it easier to assemble.
Von dieser Ausführung unterscheidet sich das in den Figuren 3 und 4 dargestellte Ausführungsbeispiel des Verschlußkörpers dadurch, dass das an dem Abdeckband 7 befestigte Klemmband 13 mit seinen rechtwinkelig abgebogenen Distanzhaltern 9 Klemmschenkel 14 aufweist, die zur Außenseite der Führungsschiene 5 ragend rechtwinkelig abgebogen sind. In diesem Fall ist die Längsnut 15 der Führungsschiene 5 tiefer ausgeführt, so dass die Distanzhalter 9 seitlich nicht geführt sind und zur Innenseite der Führungsschiene 5 ausweichen können, wenn das Abdeckband 7 mit dem Klemmband 13 in die Längsnut 15 eingedrückt wird, bis das Klemmband 7 an der Schienenoberseite 3 anliegt. Die Klemmschenkel 14 krallen sich in diesem Fall an den äußeren Begrenzungswänden der Längsnut 15 der Führungsschiene 5 fest.The embodiment of the closure body shown in FIGS. 3 and 4 differs from this embodiment in that the clamping band 13 fastened to the cover band 7, with its spacers 9 bent at right angles, has clamping legs 14 which are bent at right angles to the outside of the guide rail 5. In this case, the longitudinal groove 15 of the guide rail 5 is made deeper so that the spacers 9 are not laterally guided and can dodge to the inside of the guide rail 5 if the cover band 7 with the clamping band 13 is pressed into the longitudinal groove 15 until the clamping band 7 on the top of the rail 3 is present. In this case, the clamping limbs 14 grip the outer boundary walls of the longitudinal groove 15 of the guide rail 5.
In den Figuren 5 und 6 ist für eine erfindungsgemäße Führungsschiene 5 ein Klemmband 16 mit Klemmschenkeln 17 in Form eines Blechstreifens ausgeführt, an welchem an der Längsmittellinie in Abständen hintereinander angeordnete Distanzhalter 18 ausgeformt sind. Diese sind an der in Bezug auf die Führungsschiene 5 inneren Oberfläche des Abdeckbandes befestigt. Das Abdeckband 7 bildet mit seiner äußeren Oberfläche gemeinsam mit der Schie- nenoberseite 3 eine ebene Anlagefläche für die Frontdichtungen des zu verwendenden Führungswagens. Infolge dieser Anordnung des Verschlußkörpers in der Führungsschiene 5 ist die Längsnut 19 der Führungsschiene 5 mit Stufen ausgeführt. So weist sie einen Bereich mit etwas geringerer Breite als der Breite des Klemmbandes 16 auf, so dass die Klemmschenkel 17 sich hier an der Führungsschiene 5 festkrallen. Darunter befinden sich Absätze 20, welche die Eindrücktiefe des Verschlußkörpers begrenzen. Über dem Bereich mit den Absätzen 20 weist die Längsnut 19 einen Bereich mit noch größerer Breite auf, in welchem das Abdeckband 7 untergebracht ist.In FIGS. 5 and 6, a clamping band 16 with clamping legs 17 in the form of a sheet metal strip is designed for a guide rail 5 according to the invention, on which spacers 18 arranged one after the other at intervals along the longitudinal center line are formed. These are attached to the inner surface of the cover strip with respect to the guide rail 5. With its outer surface, the cover band 7 forms, together with the top side of the rail 3, a flat contact surface for the front seals of the guide carriage to be used. As a result of this arrangement of the closure body in the guide rail 5, the longitudinal groove 19 of the guide rail 5 is designed with steps. Thus, it has an area with a slightly smaller width than the width of the clamping band 16, so that the clamping legs 17 grip the guide rail 5 here. Below that are paragraphs 20 which limit the depth of insertion of the closure body. Over the area with the shoulders 20, the longitudinal groove 19 has an area of even greater width, in which the cover band 7 is accommodated.
Eine zu dieser Ausführung ähnliche Ausführung zeigt Figur 7. Der dort in die Längsnut 19 der Führungsschiene 5 eingesetzte Verschlußkörper unterscheidet sich nur in der Ausführung seines Klemmbandes 21 , welches mit seinen Klemmschenkeln 22 und mindestens einem Distanzhalter 23 als einstückig gebogenes Blechteil ausgeführt ist. An embodiment similar to this embodiment is shown in FIG. 7. The closure body inserted into the longitudinal groove 19 of the guide rail 5 differs only in the embodiment of its clamping band 21, which is designed with its clamping legs 22 and at least one spacer 23 as a one-piece bent sheet metal part.
