Description

Die Erfindung betrifft eine Vorrichtung, welche es gestattet, Dachlatten auf Dachsparren oder dergleichen Unterkonstruktion mit vorgegebenen Abständen zu befestigen.The invention relates to a device which allows roof battens to be attached to rafters or the like substructure at predetermined intervals.

An Dächern, die mit Ziegeln eingedeckt sind, kann man oft feststellen, daß die einzelnen horizontalen Ziegelreihen nicht geradlinig sind. Vielmehr sind Unregelmäßigkeiten in der Ziegelanordnung zu beobachten, die dem Dach ein unordentliches Aussehen verleihen.On roofs that are covered with tiles, you can often see that the individual horizontal rows of tiles are not straight. Rather, irregularities can be observed in the tile arrangement, which give the roof a messy appearance.

Da diese Beobachtungen auch bei Dächern gemacht werden können, die mit maschinell gefertigten und damit streng maßhaltigen Ziegeln eingedeckt worden sind, dürfte dieses Problem damit zusammenhängen, daß Dachlatten, auf denen die Ziegel ruhen, nicht mit der nötigen Genauigkeit verlegt und auf den Sparren befestigt worden sind.Since these observations can also be made on roofs that have been covered with machined and therefore strictly dimensionally stable tiles, this problem should be connected with the fact that roof battens on which the tiles rest were not laid with the necessary accuracy and attached to the rafters are.

Aus US-A-4350279 sowie US-A-4523706 ist eine Einlattvorrichtung bekannt, bei der die einander gegenüberliegenden Holme durch einen H-förmigen Rahmen verbunden sind. Die beiden senkrecht zu den Holmen verlaufenden Längsträger des Rahmens, die zur Anpassung an einen gewünschten Dachlattenabstand in ihrer Länge veränderlich sind, tragen die beiden parallelen Holme und deren Anlageelemente. Ferner ist an den Längsträgern parallel zu jedem der beiden Holme ein von den Längsträgern geführter und unter der Wirkung zweier starker Federn stehender Querbalken vorgesehen, an welchem die an die andere Seitenfläche der betreffenden Dachlatte heranführbaren Andruckelemente befestigt sind.From US-A-4350279 and US-A-4523706 a lath device is known in which the mutually opposite spars are connected by an H-shaped frame. The two longitudinal beams of the frame, which run perpendicular to the spars and whose length can be varied to adapt to a desired roof lath distance, carry the two parallel spars and their contact elements. Furthermore, on the longitudinal beams, parallel to each of the two spars, a crossbar guided by the longitudinal beams and under the action of two strong springs is provided which are attached to the other side surface of the relevant batten pressure elements.

Diese bekannte Vorrichtung hat den Nachteil, daß sich die Dachlatten nur sehr schwer zwischen die Anlageelemente und die unter Federdruck stehenden Andruckelemente einführen lassen. Ferner können bei dieser Vorrichtung nur im wesentlichen gerade Dachlatten verwendet werden, wenn sich nach anschließender Eindeckung mit Dachziegeln gerade Ziegelreihen ergeben sollen.This known device has the disadvantage that the roof battens are very difficult to insert between the contact elements and the pressure elements under spring pressure. Furthermore, only essentially straight battens can be used in this device if straight rows of tiles are to result after subsequent covering with roof tiles.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung anzugeben, die ein genaues und einfaches Verlegen von Dachlatten auf einem Feld von Dachsparren erlaubt.The invention is therefore based on the object of specifying a device which permits precise and simple laying of roof battens on a field of rafters.

Die der Erfindung zugrundeliegende Aufgabe wird durch eine Vorrichtung nach dem Anspruch 1 gelöst.The object on which the invention is based is achieved by a device according to claim 1.

Die Erfindung bringt den Vorteil, daß die einzulattenden Dachlatten mühelos in die Vorrichtung eingeführt werden können. Darüber hinaus erlaubt die Vorrichtung die Verwendung selbst verzogener Dachlatten, da diese vor dem Befestigen durch den seitlich auf sie ausgeübten Druck begradigt werden.The invention has the advantage that the roof battens to be battened can be easily inserted into the device. In addition, the device allows the use of warped roof battens, since these are straightened by the pressure exerted on them laterally before being fastened.

Dadurch, daß die Andruckelemente an einem Querbalken befestigt sind, der im Rahmenwerk schwenkbar und mit dem Motor gekoppelt ist, wird es möglich, eine einzulattende Dachlatte zwischen der Reihe von ersten Andruckelementen und der zugehörigen Reihe von Anlageelementen einzuspannen, zu halten, sicher zu positionieren und zu befestigen.The fact that the pressure elements are attached to a crossbar which is pivotable in the framework and coupled to the motor, it is possible to clamp, hold, securely position and securely insert a roof batten between the row of first pressure elements and the associated row of contact elements to fix.

Zweckmäßig kann auch eine eingelattete Dachlatte fest eingefangen werden, wenn eine zweite Reihe von Andruckelementen vorgesehen ist, die zur ersten Reihe von Andruckelementen parallel sich erstreckt und der zweiten Reihe von Anlageelementen zugeordnet sind. Alle Anlageelemente und Andruckelemente sind zweckmäßig mit Rollen bestückt, so daß das Rahmenwerk trotz des starken Ergreifens der Dachlatten unter Druck leicht von Hand seitlich verfahrbar ist. Die Verfahrbarkeit wird erleichtert, wenn in Weiterbildung der Erfindung das Rahmenwerk mit wenigstens zwei Rollen- oder Walzenpaaren versehen ist, von denen das erste im Bereich der ersten Reihen von Anlageelementen und Andruckelementen und das zweite Paar im Bereich der zweiten Reihen von Anlage- und Andruckelementen befestigt ist. Das Rahmenwerk kann dann von Hand über die Dachlatten seitlich hinweggerollt werden, wobei der Nagler je nach Bedarf betätigt und auf diese Weise eine neue Dachlatte auf den Sparren verlegt und befestigt werden kann.It is also expedient to firmly catch a slatted roof batten if a second row of pressure elements is provided which extends parallel to the first row of pressure elements and is assigned to the second row of contact elements. All system elements and pressure elements are expediently equipped with rollers, so that the framework can be easily moved by hand despite the strong gripping of the roof battens under pressure. Movability is facilitated if, in a further development of the invention, the framework is provided with at least two pairs of rollers or rollers, the first of which is fastened in the area of the first rows of contact elements and pressure elements and the second pair in the area of the second rows of contact and pressure elements is. The framework can then be rolled sideways over the roof battens, whereby the nailer can be operated as required and a new roof battens can be laid and fastened on the rafters in this way.

Um schließlich eine genaue Einstellung des gewünschten Dachsparrenabstands zu erleichtern, weist das Rahmenwerk einen Schlitten auf, auf welchem die zweite Reihe von Anlageelementen und die zweite Reihe von Andruckelementen befestigt sind und der beispielsweise mittels eines Spindeltriebes quer zur ersten Querleiste verfahr- und einstellbar ist.In order to finally facilitate an exact setting of the desired rafter spacing, the framework has a slide on which the second row of contact elements and the second row of pressure elements are fastened and which can be moved and adjusted transversely to the first transverse bar, for example by means of a spindle drive.

Zu weiteren bevorzugten Ausgestaltungen der Erfindung wird auf die Unteransprüche Bezug genommen.For further preferred embodiments of the invention, reference is made to the subclaims.

Die Erfindung wird nachstehend anhand des in der beigefügten Zeichnung dargestellten Ausführungsbeispiels im einzelnen beschrieben. Es zeigen:

Die erfindungsgemäße Einlattvorrichtung weist ein steifes und stabiles Rahmenwerk 2 auf, welches von zwei beabstandeten Längsträgern 4, 6, einem ersten Querträger 8 und einem Verbindungsträger 10 gebildet wird. Der erste Querträger 8 ist an den einander gegenüberliegenden Enden der Längsträger 4, 6 und der Verbindungsträger 10 mit den anderen Enden der Längsträger 4, 6 fest verbunden, so daß sich ein im wesentlichen rechtwinkliges Rahmenwerk ausreichender Steifheit ergibt.The lathing device according to the invention has a rigid and stable framework 2, which is formed by two spaced-apart longitudinal members 4, 6, a first cross member 8 and a connecting member 10. The first cross member 8 is fixedly connected at the opposite ends of the side members 4, 6 and the connecting member 10 to the other ends of the side members 4, 6, so that there is a substantially rectangular framework of sufficient rigidity.

Die gegenüberliegenden Enden 14, 16 eines Querbalken 12 sind in den Längsträgern 4, 6 drehbar gelagert, und zwar mit einem Abstand im Inneren des rechtwinkligen Rahmens 4, 6, 8, 10 zum ersten Querträger 8, der ungefähr der Breite einer Dachlatte entspricht. Der Querbalken 12 überbrückt den Abstand zwischen den Längsträgern 4, 6 parallel zum ersten Querträger 8.The opposite ends 14, 16 of a crossbar 12 are rotatably mounted in the longitudinal beams 4, 6, with a distance in the interior of the rectangular frame 4, 6, 8, 10 to the first cross member 8, which corresponds approximately to the width of a roof batten. The cross bar 12 bridges the distance between the longitudinal beams 4, 6 parallel to the first cross beam 8.

An den Längsträgern 4, 6 ist ferner ein Schlitten 20 befestigt, zu welchem Zweck in den aufeinander zuweisenden gegenüberliegenden Längsflächen der Längsträger 4, 6 Führungsnuten ausgebildet sind, die sich vom Verbindungsträger 10 bis in die Nähe des Querbalkens 12 erstrecken. In der Zeichnung ist lediglich die Führungsnut 42 des Längsträgers 4 zu erkennen (Fig. 1). Gleitstücke 24, 26 sind an den Enden des Schlittens 20 am Längsträger 4 und Längsträger 6 befestigt. Gleitstück 24 erstreckt sich in die Führungsnut 42 und das Gleistück 26 erstreckt sich in die entsprechende Führungsnut im Längsträger 6. Somit kann der Schlitten 20 innerhalb der und parallel zu den Längsträgern 4, 6 verschoben werden.A carriage 20 is also attached to the longitudinal beams 4, 6, for which purpose guide grooves are formed in the opposing longitudinal surfaces of the longitudinal beams 4, 6, which extend from the connecting beam 10 to the vicinity of the crossbeam 12. In the drawing, only the guide groove 42 of the longitudinal member 4 can be seen (Fig. 1). Sliders 24, 26 are attached to the ends of the carriage 20 on the side member 4 and side member 6. Slider 24 extends into the guide groove 42 and the slide 26 extends into the corresponding guide groove in the longitudinal beam 6. Thus, the slide 20 can be moved within and parallel to the longitudinal beams 4, 6.

An dem Schlitten 20 ist eine Einstellvorrichtung befestigt, zu welcher ein Halteblock 30, der auf der Oberfläche des Verbindungsträgers 10 in der Mitte zwischen den Längsträgern 4, 6 befestigt ist, ein Antriebsblock 32, der auf der Oberfläche des Schlittens 20 befestigt ist, sowie eine Spindel 34 gehören, die sich durch den Halteblock 30 und den Antriebsblock 32 erstreckt und mit einem Handgriff 36 an ihrem außerhalb des Rahmenwerkes 2 befindlichen freien Ende ausgerüstet ist. Die Spindel 34 ist in dem Halteblock 30 drehbar gelagert, jedoch an einer Bewegung längs ihrer Achse gehindert. Ein Innengewinde einer von der Spindel 34 durchsetzten Durchgangsbohrung im Antriebsblock 32 greift in das Außengewinde der Spindel 34 ein. Schließlich sitzt eine Gegenmutter 38 auf dem Spindelabschnitt 35 zwischen Antriebsblock 32 und Halteblock 30, welche beim Anziehen gegen den Antriebsblock eine weitere Drehung der Spindel 34 unterbindet. Durch Lockern der Gegenmutter 38 kann daher der Schlitten 20 auf jede gewünschte Position bezüglich des ersten Querträgers 8 längs der Längsträger 4, 6 durch Drehen des Handgriffes 36 eingestellt werden.An adjustment device is attached to the slide 20, to which a holding block 30, which is attached to the surface of the connecting support 10 in the middle between the longitudinal supports 4, 6, a drive block 32, which is attached to the surface of the slide 20, and a Belong to spindle 34, which extends through the holding block 30 and the drive block 32 and is equipped with a handle 36 at its free end located outside the framework 2. The spindle 34 is rotatably mounted in the holding block 30, but is prevented from moving along its axis. An internal thread of a through hole in the drive block 32 through which the spindle 34 passes engages in the external thread of the spindle 34. Finally, a lock nut 38 sits on the spindle section 35 between the drive block 32 and the holding block 30, which prevents further rotation of the spindle 34 when tightened against the drive block. By loosening the lock nut 38, the slide 20 can therefore be adjusted to any desired position with respect to the first cross member 8 along the longitudinal members 4, 6 by turning the handle 36.

Die Einlattvorrichtung besitzt fernerhin drei Gruppen von Rollen. Eine erste Rollengruppe ist in der Nähe des ersten Querträgers 8 und des Querbalkens 12 vorgesehen und umfaßt eine erste Rolle 44, die an einer Außenfläche des Längsträgers 4 um eine zur Längsrichtung des Längsträgers parallele Achse drehbar befestigt ist. Die zweite Rolle 64 der ersten Rollengruppe ist gegenüber der ersten Rolle 44 an einer nach außen weisenden Oberfläche des Längsträgers 6 derart befestigt, daß sie um eine zur Längsrichtung des Längsträgers 6 parallele Achse drehbar ist. Dazu ist jede der Rollen 44, 64 in einem U-förmigen Halter 45, 65 drehbar gelagert, wobei die Halter an den genannten Stellen an den Längsträgern 4, 6 befestigt sind. Jede der Rollen 44, 64 erstreckt sich axial im wesentlichen über den gesamten Abstand zwischen dem ersten Querträger 8 und dem Querbalken 12. Weiterhin ist zu bemerken, daß ein Teil der zylindrischen Außenfläche jeder der Rollen 44, 64 unter die Unterseite des Rahmenwerkes 2 soweit vorsteht, daß das Rahmenwerk 2 auf einer nicht dargestellten Dachlatte mittels der Rollen 44, 64 abrollen kann.The Einlattvorrichtung also has three groups of roles. A first roller group is provided in the vicinity of the first cross member 8 and the cross beam 12 and comprises a first roller 44 which is fastened to an outer surface of the side member 4 so as to be rotatable about an axis parallel to the longitudinal direction of the side member. The second roller 64 of the first roller group is fixed relative to the first roller 44 on an outwardly facing surface of the side member 6 such that it can be rotated about an axis parallel to the longitudinal direction of the side member 6. Is to each of the rollers 44, 64 is rotatably mounted in a U-shaped holder 45, 65, the holders being fastened to the longitudinal beams 4, 6 at the locations mentioned. Each of the rollers 44, 64 extends axially substantially over the entire distance between the first cross member 8 and the cross beam 12. Furthermore, it should be noted that part of the cylindrical outer surface of each of the rollers 44, 64 protrudes so far below the underside of the framework 2 that the framework 2 can roll on a roof batten, not shown, by means of the rollers 44, 64.

Eine zweite Rollengruppe mit den Rollen 22, 28 ist am Schlitten 20 vorgesehen. So ist Rolle 22 in der Nähe des Gleitstückes 24 und Rolle 28 in der Nähe des Gleistückes 26 befestigt. Die Rollen 22, 28 können sich um Achsen drehen, die parallel zu den Drehachsen der Rollen 44, 64 sich erstrecken. Auch von den Rollen 22, 28 ist zu bemerken, daß ein Teil des zylindrischen Umfanges desselben über die Unterseite des Rahmenwerkes 2 soweit vorsteht, daß das Rahmenwerk auf einer weiteren Dachlatte über die Rollen 22, 28 abrollen kann.A second group of rollers with the rollers 22, 28 is provided on the carriage 20. Thus, roller 22 is fastened in the vicinity of the slider 24 and roller 28 in the vicinity of the slide 26. The rollers 22, 28 can rotate about axes that extend parallel to the axes of rotation of the rollers 44, 64. Also of the rollers 22, 28 it should be noted that part of the cylindrical circumference thereof projects beyond the underside of the framework 2 to such an extent that the framework can roll over the rollers 22, 28 on a further batten.

Ein drittes Rollenpaar mit Rollen 46 und 66 ist an dem dem ersten Querträger 8 gegenüberliegende Ende des Rahmenwerkes 2 vorgesehen. Dazu sind U-förmige Rollenhalter 47, 67 an den Längsträgern 4, 6 außen in der Nähe des Verbindungsträgers 10 befestigt. Die Drehachsen der Rollen 46, 66 erstrecken sich wieder parallel zu denjenigen der Rollen 22, 28 und ermöglichen es, daß das Rahmenwerk auf einer weiteren befestigten Dachlatte abrollen kann.A third pair of rollers with rollers 46 and 66 is provided on the end of the framework 2 opposite the first cross member 8. For this purpose, U-shaped roll holders 47, 67 are fastened to the longitudinal beams 4, 6 on the outside in the vicinity of the connecting beam 10. The axes of rotation of the rollers 46, 66 again extend parallel to those of the rollers 22, 28 and allow the framework to roll on another attached roof batten.

Die Einlattvorrichtung weist insgesamt sieben Anlageelemente 52, 54, 56, 58, 72, 74, 76 auf, die von der Unterseite des Rahmenwerkes 2 vorstehen. Eine erste Reihe 50 von Anlageelementen 52, 54, 56, 58 sind an der Unterfläche des ersten Querträgers 8 befestigt. Die erste Reihe 50 von Anlageelementen erstreckt sich entlang des ersten Querträgers 8 und senkrecht zur Längsrichtung der Längsträger 4, 6.The Einlattvorrichtung has a total of seven contact elements 52, 54, 56, 58, 72, 74, 76, which protrude from the underside of the framework 2. A first row 50 of contact elements 52, 54, 56, 58 are fastened to the lower surface of the first cross member 8. The first row 50 of contact elements extends along the first cross member 8 and perpendicular to the longitudinal direction of the longitudinal members 4, 6.

Eine zweite Reihe 70 von Anlageelementen 72, 74, 76 ist an einem zweiten Querträger 78 befestigt, der den Vorderabschnitt des Schlittens 12 bildet und sich parallel zum ersten Querträger 8 erstreckt.A second row 70 of contact elements 72, 74, 76 is fastened to a second cross member 78, which forms the front section of the carriage 12 and extends parallel to the first cross member 8.

Alle Anlageelemente sind im Aufbau gleich, so daß es genügt, nur das Anlageelement 52 im einzelnen zu erläutern. Das Anlageelement 52 besteht aus einem Schaft 51 und einem auf diesem gehaltenen Kugellager 55. Der Schaft 51 ist im Preßsitz in eine Blindbohrung eingesetzt, die von der Unterfläche des ersten Querträgers 8 her in diesen eingebracht ist. Der aus der Unterseite des ersten Querträgers 8 nach unten vorstehende Teil des Schaftes 51 trägt unverdrehbar die Innenschale 53 des Kugellagers 55, dessen Außenschale 57 um die Achse des Schaftes 51, d. h. parallel zur Unterseite des ersten Querträgers 8, frei drehbar ist.All contact elements are identical in construction, so that it is sufficient to explain only the contact element 52 in detail. The contact element 52 consists of a shaft 51 and a ball bearing 55 held thereon. The shaft 51 is press-fitted into a blind hole which is introduced into the first cross member 8 from the lower surface thereof. The part of the shaft 51 projecting downward from the underside of the first cross member 8 non-rotatably supports the inner shell 53 of the ball bearing 55, the outer shell 57 of which about the axis of the shaft 51, i.e. H. parallel to the underside of the first cross member 8, is freely rotatable.

Es versteht sich, daß statt eines Kugellagers 55 auch eine Rolle oder ein Laufrad auf dem Schaft 51 frei um dessen Achse drehbar sitzen kann. Jedoch muß Vorsorge dafür getroffen werden, daß der Einspanndruck der Dachlatten, wie er von den noch zu erläuternden Andruckelementen ausgeübt wird, von den Rollen oder Laufrädern ohne weiteres aufgenommen werden kann.It goes without saying that instead of a ball bearing 55, a roller or an impeller can also be freely rotatable on the shaft 51 about its axis. However, precautions must be taken to ensure that the clamping pressure of the roof battens, as exerted by the pressure elements still to be explained, can be easily absorbed by the rollers or running wheels.

Somit weist jedes Anlageelement 52, 54, 56, 58; 72, 74, 76 ein Kugellager auf, dessen Außenschale um eine Achse frei drehbar ist, die senkrecht auf der durch das Rahmenwerk 2 definierten Ebene steht.Each contact element 52, 54, 56, 58; 72, 74, 76 a ball bearing, the outer shell of which is freely rotatable about an axis which is perpendicular to the plane defined by the framework 2.

Während die Anlageelemente der zweiten Reihe 70 untereinander gleichen Abstand längs des zweiten Querträgers 78 haben, weist die erste Reihe 50 einen ungleichmäßigen Abstand zwischen den zu dieser Reihe gehörenden Anlageelementen auf, insofern als die beiden mittleren Anlageelemente 54, 56 enger beieinander angeordnet sind, als die übrigen Anlageelemente dieser Reihe.While the contact elements of the second row 70 have the same distance from one another along the second cross member 78, the first row 50 has an uneven distance between the contact elements belonging to this row, in that the two middle contact elements 54, 56 are arranged closer together than that other investment elements in this series.

Eine erste Reihe 80 von Andruckelementen 82, 84, 86, 88 erstreckt sich parallel zu der ersten Reihe 50 von Anlageelementen. Die Andruckelemente 82, 84, 86, 88 sind an der Unterfläche des Querbalkens 12 so befestigt, daß sich jeweils ein Anlageelement 52, 54, 56, 58 einem zugehörigen Andruckelement 82, 84, 86, 88 gegenüber befindet. Jedes Andruckelement 82, 84, 86, 88 ist von gleicher Art und Bauweise wie die Anlageelemente und umfaßt daher einen am Querbalken 12 fest befestigten Schaft und ein an dessen freiem Ende befestigtes Kugellager, welches um die Achse des Schaftes frei drehbar ist.A first row 80 of pressure elements 82, 84, 86, 88 extends parallel to the first row 50 of contact elements. The pressure elements 82, 84, 86, 88 are fastened to the lower surface of the crossbar 12 in such a way that one contact element 52, 54, 56, 58 is located opposite an associated pressure element 82, 84, 86, 88. Each pressure element 82, 84, 86, 88 is of the same type and construction as the contact elements and therefore comprises a shaft fixedly attached to the crossbeam 12 and a ball bearing attached to the free end thereof, which is freely rotatable about the axis of the shaft.

Eine zweite Reihe 90 von Andruckelementen 92, 94 ist auf dem Schlitten 20 vorgesehen und der zweiten Reihe 70 von Anlageelementen 72, 74, 76 zugeordnet. Jedes Andruckelement 92, 94 weist wieder ein Kugellager auf, dessen Außenschale um die Achse eines Hebels frei drehbar ist, der noch weiter unten erläutert werden wird.A second row 90 of pressure elements 92, 94 is provided on the slide 20 and assigned to the second row 70 of contact elements 72, 74, 76. Each pressure element 92, 94 again has a ball bearing, the outer shell of which can be freely rotated about the axis of a lever, which will be explained further below.

Der Schlitten 20 besteht im wesentlichen aus einer Platte, in welche zwei rechtwinklige Öffnungen 21, 23 geschnitten sind. In der ersten Öffnung 21 ist die Rolle 22 gehalten und in der zweiten Öffnung 23 ist die Rolle 26 gehalten. Der vordere Abschnitt der Platte ist der zweite Querträger 78, der mit einem rückwärtigen Abschnitt 27 des Schlittens 20 durch drei Arme 31, 33, 37 verbunden ist.The carriage 20 consists essentially of a plate in which two right-angled openings 21, 23 are cut. The roller 22 is held in the first opening 21 and the roller 26 is held in the second opening 23. The front portion of the plate is the second cross member 78 which is connected to a rear portion 27 of the carriage 20 by three arms 31, 33, 37.

Ein erster Stützblock 39 ist auf dem rückwärtigen Abschnitt 27 und auf dem zweiten Querträger 78 befestigt und trägt einen ersten Druckluftmotor 91 für das Andruckelement 92. Die Kolbenstange 93 des Zylinders 91 ist mit einem Ende eines Hebels 95 schwenkbar verbunden. Der Hebel 95 kann um einen nicht dargestellten, in dem rückwärtigen Abschnitt 27 befestigten Stift und damit um eine Achse kippen, die parallel zur Schwenkachse des Querbalkens 12 ist. Das freie, unter den Schlitten 20 bewegbare Ende des Hebels 95 trägt das Andruckelement 92.A first support block 39 is fastened on the rear section 27 and on the second cross member 78 and carries a first compressed air motor 91 for the pressure element 92. The piston rod 93 of the cylinder 91 is pivotally connected to one end of a lever 95. The lever 95 can tilt about a pin (not shown) fastened in the rear section 27 and thus about an axis that is parallel to the pivot axis of the crossbar 12. The free end of the lever 95 which can be moved under the carriage 20 carries the pressure element 92.

Ein zweiter Stützblock 41 ist bezüglich des Antriebsblockes 32 gegenüber dem Stützblock 39 auf dem rückwärtigen Abschnitt 27 und auf dem zweiten Querträger 78 befestigt und trägt einen zweiten Druckluftmotor 71. Die Kolbenstange 73 des Zylinders 71 ist an ein Ende eines Hebels 75 angelenkt. Der Hebel 75, dessen freies unter den Schlitten 20 bewegbares Ende das Andruckelement 94 trägt, ist am rückwärtigen Abschnitt 27 um eine Achse schwenkbar angelenkt, die parallel zur Schwenkachse des Hebels 95 verläuft. Somit können die Andruckelemente 92, 94 durch entsprechende Betätigung der Motore 71, 91 um eine Achse verschwenkt werden, die parallel zur Reihe 70 der zugehörigen Anlageelemente verläuft.A second support block 41 is fastened with respect to the drive block 32 opposite the support block 39 on the rear section 27 and on the second cross member 78 and carries a second compressed air motor 71. The piston rod 73 of the cylinder 71 is articulated to one end of a lever 75. The lever 75, the free end of which can be moved under the carriage 20 and carries the pressure element 94, is articulated on the rear section 27 about an axis which runs parallel to the pivot axis of the lever 95. Thus, the pressing elements 92, 94 can be pivoted about an axis by corresponding actuation of the motors 71, 91, which axis runs parallel to the row 70 of the associated contact elements.

Zum Verschwenken des Querbalkens 12 dienen zwei weitere parallel geschaltete Druckluftmotore, welche auf der Oberfläche des ersten Querträgers 8 befestigt sind. Der Pneumatikzylinder 81 ist an dem Träger 8 befestigt und die Kolbenstange 81 ist an eine sich über den Balken 12 nach oben erhebende Nocke 85 angelenkt. Ein Zylinder 87 eines zweiten Druckluftmotors ist auf der Oberfläche des ersten Querträgers 8 befestigt und besitzt eine Kolbenstange 89, die mit einer weiteren, nicht dargestellten, sich über den Balken 12 erhebenden Nocke schwenkbar verbunden ist.Two further compressed air motors connected in parallel, which are fastened on the surface of the first cross member 8, serve to pivot the cross bar 12. The pneumatic cylinder 81 is fastened to the carrier 8 and the piston rod 81 is articulated to a cam 85 which rises above the bar 12. A cylinder 87 of a second compressed air motor is attached to the surface of the first cross member 8 and has a piston rod 89 which is pivotally connected to a further cam (not shown) which rises above the beam 12.

Druckluftleitungen 96 verbinden den Zylinder 91 und Druckluftleitungen 97 verbinden den Zylinder 71 mit Druckluftleitungen 98, welche zu einem Steuerkasten 18 führen. Entsprechend sind die Zylinder 71 und 87 mit Druckluftleitungen 99 verbunden, die ebenfalls zu dem Steuerkasten 18 führen. Wie dargestellt, besteht jede Druckluftleitung aus einem Leitungspaar, wie das für die Betätigung von Druckluftzylindern in der einen oder anderen Richtung üblich ist.Compressed air lines 96 connect the cylinder 91 and compressed air lines 97 connect the cylinder 71 to compressed air lines 98, which lead to a control box 18. Correspondingly, the cylinders 71 and 87 are connected to compressed air lines 99, which also lead to the control box 18. As shown, each compressed air line consists of a pair of lines, as is usual for the actuation of compressed air cylinders in one direction or the other.

Der erste Querträger 8 trägt ferner einen aufrechten ersten Bügel 100, und der Verbindungsträger 10 trägt einen zweiten aufrechten Bügel 102. Eine Platte 104 verbindet die oberen Teile des ersten Bügels 100 mit dem oberen Teil des zweiten Bügels 102. Der Steuerkasten 18 ist an der Verbindungsplatte 104 befestigt, über welche sich ein erster Steuerknopf 106 erhebt. Der Steuerkasten 18 enthält ein System von Druckluftleitungen und Ventilen, welche es gestatten, die hier beschriebenen Funktionen der Vorrichtung auszuführen. Druckluft-Anschlußleitungen 108 verbinden den Steuerkasten 18 mit einer nicht dargestellten Druckluftquelle. Es versteht sich, daß die Druckluftleitungen 98, 99 durch das Leitungssystem im Steuerkasten 18 mit einer Druckluftquelle verbunden sind, wenn der Steuerknopf 106 auf die entsprechende Stellung manuell eingestellt wird. Wenn somit alle vier Druckluftmotoren 71, 91, 81, 87 durch die zugehörige Druckluftleitung aktiviert werden, werden die zugehörigen Kolbenstangen 73, 93, 83, 89 in Richtung auf das eine Ende des zugehörigen Zylinders mit dem Ergebnis verschoben, daß der Querbalken 12 wie auch die zweite Reihe 90 von zweiten Andruckelementen 92, 94 sich in Uhrzeigerrichtung drehen werden, und zwar soweit, wie dies der Hubweg der Kolbenstangen zuläßt oder bis die Andruckelemente zu seitlicher Anlage an eine einzulattende und eine eingelattete Dachlatte gelangen. Es versteht sich, daß dann alle Andruckelemente wie auch alle Anlageelemente sich auf einem Niveau befinden, das etwa der halben durchschnittlichen Stärke von einzulattenden Dachlatten entspricht.The first cross member 8 also carries an upright first bracket 100 and the connecting bracket 10 carries a second upright bracket 102. A plate 104 connects the upper parts of the first bracket 100 to the upper part of the second bracket 102. The control box 18 is on the connecting plate 104 attached, over which a first control button 106 rises. The control box 18 contains a system of compressed air lines and valves which allow the functions of the device described here to be carried out. Compressed air connecting lines 108 connect the control box 18 to one, not shown Compressed air source. It is understood that the compressed air lines 98, 99 are connected to a compressed air source by the line system in the control box 18 when the control button 106 is manually set to the appropriate position. Thus, when all four air motors 71, 91, 81, 87 are activated by the associated air line, the associated piston rods 73, 93, 83, 89 are displaced towards one end of the associated cylinder with the result that the crossbar 12 as well the second row 90 of second pressure elements 92, 94 will rotate in the clockwise direction, to the extent that the stroke of the piston rods permits or until the pressure elements come to rest laterally against a batten that is to be slatted in and a slatted roof batten. It goes without saying that then all pressure elements as well as all contact elements are at a level which corresponds to approximately half the average thickness of roof battens to be lattened.

Wenn andererseits die Druckluftmotore 71, 91, 81, 87 durch eine Beaufschlagung von Druckluft der entsprechenden Druckluftleitungen in umgekehrter Richtung aktiviert werden, werden die zugehörigen Kolbenstangen 73, 93, 83, 89 in die zugehörigen Zylinder mit der Folge hineingezogen, daß der Querbalken 12 und die zweite Reihe von zweiten Andruckelementen 92, 94 sich im Gegensinn des Uhrzeigers drehen werden.On the other hand, if the compressed air motors 71, 91, 81, 87 are activated by applying compressed air to the corresponding compressed air lines in the opposite direction, the associated piston rods 73, 93, 83, 89 are drawn into the associated cylinders with the result that the crossbeams 12 and the second row of second pressure elements 92, 94 will rotate counterclockwise.

Ein automatischer Nagler 120 ist an dem ersten Querträger 8 sowie an der Kolbenstange 122 eines Pneumatikzylinders 124 befestigt. Der Pneumatikzylinder 124 ist auf der Oberseite der Platte 104 befestigt, und die Kolbenstange 124 ist mit dem Deckel des Korpus 126 des Naglers 120 verbunden und erstreckt sich durch eine Bohrung in der Platte 104. Der Naglerkopf 128 wird in vertikalen Schienen 130, 132 geführt, die an dem ersten Querträger 8 befestigt sind. Eine Druckluftleitung 134 verbindet den Pneumatikzylinder 124 mit dem Steuerkasten 18, und eine Druckluftleitung 136 verbindet den Auslöser 138 des Naglers 120 mit dem Steuerkasten 18. Ein Druckknopf 140 ist am Steuerkasten 18 vorgesehen, der eine Betätigung des Naglers 120 erlaubt.An automatic nailer 120 is fastened to the first cross member 8 and to the piston rod 122 of a pneumatic cylinder 124. The pneumatic cylinder 124 is attached to the top of the plate 104, and the piston rod 124 is connected to the cover of the body 126 of the nailer 120 and extends through a bore in the plate 104. The nailer head 128 is guided in vertical rails 130, 132 which are fastened to the first cross member 8. A compressed air line 134 connects the pneumatic cylinder 124 to the control box 18, and a compressed air line 136 connects the trigger 138 of the nailer 120 to the control box 18. A push button 140 is provided on the control box 18, which allows the nailer 120 to be actuated.

Handgriffe 142, 144 sind am oberen Teil der Bügel 100 und 102 befestigt, so daß die Einlattvorrichtung leicht von Hand transportiert werden kann. Ein weiterer Handgriff 146 ist auf der Platte 104 befestigt, der ein Verschieben der Einlattvorrichtung längs der Dachlatten erlaubt.Handles 142, 144 are attached to the upper part of the brackets 100 and 102 so that the lathing device can be easily transported by hand. Another handle 146 is fastened on the plate 104, which allows the slat device to be moved along the roof slats.

Zum Auslegen und Befestigen einer Dachlatte in einem vorgegebenem Abstand oberhalb einer befestigten Dachlatte wird der Schalter 106 in eine Position gedreht, die die Freigabe der ersten Reihe 80 der ersten Andruckelemente und der zweiten Reihe 90 der zweiten Andruckelemente veranlaßt, so daß die Andruckelemente eine Stellung einnehmen werden, wie sie aus Fig. 2 zu erkennen ist.To lay out and fasten a roof batten at a predetermined distance above a fixed roof batten, the switch 106 is rotated into a position which causes the release of the first row 80 of the first pressing elements and the second row 90 of the second pressing elements, so that the pressing elements assume a position are as can be seen from Fig. 2.

Die Einlattvorrichtung wird dann auf die letzte befestigte Dachlatte so aufgesetzt, daß die zweite Reihe 70 von Anlageelementen 72, 74, 76 an die in der Dachfläche nach oben weisende Längsseite der befestigten Dachlatte anliegen. Eine neue zu befestigende Dachlatte wird in den Zwischenraum zwischen der ersten Reihe 50 der ersten Anlageelemente und der ersten Reihe 80 von Andruckelementen eingebracht.The lathing device is then placed on the last attached roof batten in such a way that the second row 70 of contact elements 72, 74, 76 bear against the long side of the attached roof batten facing upwards in the roof surface. A new roof batten to be fastened is placed in the space between the first row 50 of the first contact elements and introduced the first row 80 of pressure elements.

Wenn der Steuerschalter 106 in eine Stellung gebracht wird, die eine Aktivierung der Motore 71, 81, 91, 87 veranlaßt, schwingt die erste Reihe von Andruckelementen in Uhrzeigerrichtung unter Druck gegen die Seitenfläche der zu befestigten Dachlatte, die daraufhin zwischen der ersten Reihe 80 von Andruckelementen und der ersten Reihe 50 von Anlageelementen mit Druck eingespannt ist. Gleichzeitig wird die Einlattvorrichtung auf der bereits eingelatteten Dachlatte festgehalten, weil die zweite Reihe 90 von Andruckelementen aufgrund der Aktivierung der genannten Motore die eingelattete Dachlatte zwischen der zweiten Reihe 70 von Anlageelementen und der zweiten Reihe 90 von Andruckelementen eingespannt hat.When the control switch 106 is brought into a position which causes the motors 71, 81, 91, 87 to be activated, the first row of pressure elements swings clockwise under pressure against the side surface of the roof batten to be fastened, which then passes between the first row 80 of Pressure elements and the first row 50 of system elements is clamped with pressure. At the same time, the lathing device is held on the already battened roof batten because the second row 90 of pressure elements has clamped the battened roof batten between the second row 70 of contact elements and the second row 90 of pressure elements due to the activation of the motors mentioned.

Man sieht, daß sämtliche Kugellager oder Rollen jedes der Andruckelemente 82, 84, 86, 88, 92, 94 und jedes der Anlageelemente 52, 54, 56, 58, 72, 74, 76 jetzt in einer gemeinsamen Ebene unterhalb des Rahmenwerkes 2 sich befinden, so daß die Anlageelemente und die Andruckelemente die Dachlatten etwa in der Mitte ihrer Stärke einspannen, wohingegen die Rollen 44, 64 und 22, 28 auf den Dachlatten ruhen und auf deren Oberfläche abrollen können.It can be seen that all ball bearings or rollers of each of the pressure elements 82, 84, 86, 88, 92, 94 and each of the contact elements 52, 54, 56, 58, 72, 74, 76 are now in a common plane below the framework 2 , so that the contact elements and the pressure elements clamp the roof battens approximately in the middle of their thickness, whereas the rollers 44, 64 and 22, 28 rest on the roof battens and can roll on their surface.

Die jetzt zwischen den Reihen 50 und 80 eingespannte Dachlatte ist bereit, befestigt zu werden. Daher wird die Bedienungsperson den Druckknopf 140 niederdrücken, was zu einer Aktivierung des Pneumatikmotors 124 führt. Dieser veranlaßt, daß der Nagler sich abwärts auf die eingespannte Dachlatte zu bewegt; danach wird ein Druckimpuls über die Druckluftleitung 136 den Nagler auslösen, so daß aus dem Naglerkopf ein Nagel durch die Dachlatte geschossen wird, die daraufhin auf einem nicht dargestellten Dachsparren befestigt ist. Bei Betrachtung von Fig. 2 sieht man, daß die Dachlatte durch die Anlageelemente 54 und 56 und die Andruckelemente 84, 86 in unmittelbarer Nachbarschaft des Naglerkopfes 128 gehalten ist.The roof batten now clamped between rows 50 and 80 is ready to be attached. Therefore, the operator will depress the push button 140, which will activate the pneumatic motor 124. This causes the nailer to move downward towards the clamped roof batten; after that will be a Trigger the pressure impulse via the compressed air line 136 so that a nail is shot from the nail head through the roof batten, which is then fastened to a rafters, not shown. 2, it can be seen that the roof batten is held in the immediate vicinity of the nailer head 128 by the contact elements 54 and 56 and the pressure elements 84, 86.

Die Bedienungsperson rollt dann die Einlattvorrichtung längs der befestigten Dachlatte und nach einer vorgegebenen Entfernung, wenn beispielsweise die nächste Dachsparre unter dem Naglerkopf erscheint, wird ein weiterer Nagel in die einzulattende Dachlatte geschossen.The operator then rolls the lattice device along the attached roof lath and after a predetermined distance, for example when the next roof barrier appears under the nail head, another nail is shot into the roof lath to be lathed.

Zum Lösen der Einlattvorrichtung von den Dachsparren und/oder zur Einfügung einer weiteren einzulattenden Dachlatte wird der Steuerschalter 106 wieder umgelegt, um dadurch die oben beschriebene Funktion auszulösen.To release the lathing device from the rafters and / or to insert a further lath to be lathed, the control switch 106 is flipped again in order to thereby trigger the function described above.
