    Der Riemen 16 wird in den Bodenteil 1 zwischen seiner Basis und dem Klinkenstück 7 des Spannhebels 4 eingeführt, bis der verzahnten Teil des Riemens 16 in den verzahnten Teil 13, 13' der Rücklaufsperre 11 eingreift. Wenn der Spannhebel 4 in Richtung des Pfeiles A um die Anlenkachse 5 von der geschlossenen Stellung bis zur maximalen Öffnungsstellung geschwenkt wird, wird mit dieser Bewegung, bei der sich gleichzeitig das mit dem Arm 7'' in den Zahnriemen 16 eingreifende Klinkenstück 7 bis zum Berühren des Anschlages 10 um die Anlenkachse 8 verdreht, der Zahnriemen 16 in Richtung des Pfeiles B transportiert und somit die Schwenkbewegung des Spannhebels 4 und des Klinkenstückes 7 in eine lineare Translationsbewegung des Zahnriemens 16 verwandelt. Die auf diese Linearbewegung des Riemens übertragene Kraft überwindet den Widerstand der Feder 14 der Rücklaufsperre 11, sodaß das Hindurchführen des Zahnriemens 16 mit sukzessivem Einrasten des verzahnten Teils 13, 13' der Rücklaufsperre 11 in aufeinanderfolgenden verzahnten Teilstücken des Riemens 16 ermöglicht wird.The belt 16 is in the bottom part 1 between its base and the pawl piece 7 of the Tension lever 4 inserted until the toothed part of the belt 16 in the toothed part 13, 13 'of the backstop 11 engages. If the clamping lever 4 in the direction of arrow A around the Articulation axis 5 pivoted from the closed position to the maximum open position with this movement, which is simultaneously the arm 7 '' in the toothed belt 16 engaging pawl 7 until touching the stop 10 around Articulation axis 8 rotated, the toothed belt 16 transported in the direction of arrow B and thus the pivoting movement of the clamping lever 4 and the pawl piece 7 in a linear translation movement of the toothed belt 16 transformed. The on this linear movement of the belt Transmitted force overcomes the resistance of the spring 14 of the backstop 11, so that Passing the toothed belt 16 with successive engagement of the toothed part 13, 13 ' the backstop 11 allows in successive toothed sections of the belt 16 becomes.

    Solche Schwenkbewegungen des Spannhebels 4 werden ausgeführt, bis der Schuh fest verschlossen ist, wobei durch die erfindungsgemäße Konstruktion gewahrleistet wird, daß bei der Verschiebebewegung des Riemens 16 mindestens ein Zahn je Öffnen und Schließen des Spannhebels 4 überwunden wird. Nach dem gewünschten Verschließen bringt man den Spannhebel 4 in seine vollständig geschlossene Stellung, in der einander zugeordnete Einrastmittel 6, 6', 6'' ein versehentliches Öffnen des Spannhebels 4 verhindern und der Spannhebel 4 in dieser Stellung den Mechanismus gegen Eindringen von Fremdkörpern abdeckt. In einer weiteren, hier nicht gezeigten Ausführungsform, kann der Spannhebel 4 zusätzlich mittels einer in Transportrichtung B hinter dem Verschluß liegenden Klammer, die in Längsrichtung bewegbar am Zahnriemen 16 oder fest am Bodenteil 1 angebracht ist, zusätzlich gegen versehentliches Öffnen gesichert werden.Such pivoting movements of the clamping lever 4 are carried out until the shoe is firmly closed is, it is ensured by the construction according to the invention that at the displacement movement of the belt 16 at least one tooth per opening and closing the Clamping lever 4 is overcome. After the desired closure you bring the Clamping lever 4 in its fully closed position, in the associated one Locking means 6, 6 ', 6' 'prevent accidental opening of the tensioning lever 4 and the Clamping lever 4 in this position the mechanism against the ingress of foreign bodies covers. In a further embodiment, not shown here, the tensioning lever 4 additionally by means of a clamp lying behind the closure in the transport direction B, the is movable in the longitudinal direction on the toothed belt 16 or is fixedly attached to the base part 1, additionally secured against accidental opening.

    Bei der Schließbewegung des Spannhebels 4, drückt das Klinkenstück 7, auf dessen Arm 7' sich die Feder 9 befindet, mit diesem Arm auf die Rücklaufsperre 11 und überwindet den Widerstand der Feder 9, sodaß, wie in Fig. 2 zu sehen ist, eine Verdrehung des Klinkenstückes 7 um einen bestimmten Winkel bewirkt wird. Diese Drehung ermöglicht es, bei geschlossenem Hebel 4, eine bemerkenswerte Reduktion der sich zwischen dem Klinkenstück 7 und dem verzahnten Teil des Riemens 16 in Richtung des Pfeiles B bildenden Öffnung des Mechanismus zu erzielen. Das bringt den großen Vorteil mit sich, daß die Wahrscheinlichkeit des Eindringens von Fremdkörpern in den Verschließmechanismus erheblich reduziert wird.During the closing movement of the clamping lever 4, the pawl piece 7 presses on the arm 7 ' is the spring 9, with this arm on the backstop 11 and overcomes the Resistance of the spring 9, so that, as can be seen in Fig. 2, a rotation of the pawl piece 7 is caused by a certain angle. This rotation allows when closed Lever 4, a remarkable reduction in the distance between the jack piece 7 and the toothed part of the belt 16 in the direction of arrow B forming the opening Mechanism. This has the great advantage that the probability the penetration of foreign bodies into the closing mechanism is considerably reduced.

    Zum Nachlassen oder Öffnen des Verschlusses öffnet man den Spannhebel 4 und drückt den Arm 15 der Rücklaufsperre 11 in Richtung Basis des Bodenteils 1, wodurch die eingerasteten Nasen 13, 13' der Sperre 11 von den in der Nähe der Rücklaufsperre liegenden Zähnen des Zahnriemens 16 getrennt werden. Durch das Öffnen des Spannhebels 4 wird der Spannmechanismus etwas aktiviert, das heißt, durch ein Eingreifen des Klinkenstückes 7 in den Zahnriemen 16 wird eine teilweise Entlastung der Rücklaufsperre 11 erzielt und somit der Trennvorgang der korrespondierenden Verzahnungen erleichtert. Dies bedeutet vor allem in Hinblick darauf, daß der Verschluß vielseitig und unter verschiedensten äußeren Bedingungen, wie z.B. Schnee, Schmutz, Nässe, Kälte eingesetzt wird, einen erheblichen Vorteil, denn dadurch wird eine unter solchen Bedingungen leicht mögliche Beschädigung der entsprechenden Verzahnungen vermieden, wodurch dem Verschluß eine lange Lebensdauer garantiert wird. In einer anderen Ausführungsform kann der Spannhebel 4 eine in Fig. 3 zu sehende Ausnehmung 4''' aufweisen, die den Zugang zum Lösen der Rücklaufsperre 11 ohne Öffnen des Spannhebels 4 gestattet. Bei einer solchen Ausführungsform kann das Klinkenstück 7 einarmig in Richtung Arbeitsbereich und die Feder 9 als Spiralfeder um die Achse 8 ausgebildet sein, womit wieder die erfindungsgemäße Wirkungsweise erreicht wird.To release or open the lock, open the clamping lever 4 and press the Arm 15 of the backstop 11 in the direction of the base of the base part 1, whereby the engaged Noses 13, 13 'of the lock 11 of the teeth of the near the backstop Toothed belt 16 are separated. By opening the clamping lever 4, the clamping mechanism something activated, that is, by engaging the pawl piece 7 in the Toothed belt 16 is a partial relief of the backstop 11 and thus the Separation process of the corresponding gears easier. This means especially in Considering that the closure is versatile and under a wide variety of external conditions, such as. Snow, dirt, wet, cold is used, a significant advantage because this will easily damage the appropriate gears avoided, which gives the closure a long life is guaranteed. In another embodiment, the tensioning lever 4 can be closed in FIG. 3 seeing recess 4 '' ', which have access to release the backstop 11 without Opening the clamping lever 4 allowed. In such an embodiment, the jack piece 7 with one arm in the direction of the work area and the spring 9 as a spiral spring around the axis 8 be formed, with which the mode of operation according to the invention is again achieved.

    Um ein Zurückspringen des in den Zahnriemen 16 eingreifenden Klinkenstückes 7 nach jeder Schwenkbewegung des Spannhebels 4 in seine ursprüngliche Lage vor dem Spannzyklus und einen besseren Eingriff des Armes 7'' in die Zähne des Zahnriemens 16 zu ermöglichen, ist in dem in Transportrichtung B vor und/oder nach dem Spannhebel liegenden Basisteil des Bodenteils 1 ein Vorsprung 2 ausgebildet, über den der Zahnriemen 16 so gleitet, daß zwischen dem Bodenteil 1 und dem Riemen 16 ein Zwischenraum zum Zurückspringen der Nocke des Klinkenstückes durch Biegung des Zahnriemens 16, sowie zum Gewährleisten eines formschlüssigen Eingriffs des Klinkenstückarmes 7'' in den Zahnriemen 16 erzeugt wird, ohne daß der Riemen beim Betätigen des Klinkenstückes 7 beschädigt wird. Das Zurückspringen des Klinkenstückes nach dem Ende jedes Spannzyklus wird durch die Feder 9 unterstützt bzw. beschleunigt. Durch diese erfindungsgemäße Wirkungsweise wird eine möglichst lange Eingreifstrecke des Klinkenstückes in den Zahnriemen und somit ein maximaler Transportweg je Spannzyklus ermöglicht.In order for the latching piece 7 engaging in the toothed belt 16 to spring back after each Swiveling movement of the clamping lever 4 in its original position before the clamping cycle and A better engagement of the arm 7 ″ in the teeth of the toothed belt 16 is shown in FIG the base part of the lying in the transport direction B before and / or after the tensioning lever Bottom part 1 formed a projection 2, over which the toothed belt 16 slides so that between the bottom part 1 and the belt 16 a space for springing back Cam of the pawl piece by bending the toothed belt 16, as well as to ensure positive engagement of the pawl arm 7 ″ in the toothed belt 16 is generated, without the belt being damaged when the pawl piece 7 is actuated. The The spring piece 9 springs back after the end of each tensioning cycle supports or accelerates. By this mode of operation according to the invention as long as possible distance of engagement of the pawl piece in the toothed belt and thus a allows maximum transport distance per clamping cycle.
