Description

Armbrustcrossbow
Die Erfindung betrifft eine Armbrust, bestehend aus einem an einen Anschlagkolben anschliessenden, die Pfeilführung aufnehmenden Träger, an welchem eine an der mit dem Abschussschlitten verbundenen Sehne des spannbar am Träger verankerten Bogens angreifbare, ein den Abschuss¬ schlitten gegen eine AbzugsVorrichtung bewegbares Stossele ent aufwei¬ sende, hebe!artig betätigbare Spann orrichtung vorgesehen ist.The invention relates to a crossbow consisting of a support adjoining a stop piston and receiving the arrow guide, on which a push rod ent which can be attacked on the tendon of the bow which is anchored to the support slide of the bow and which is movably anchored on the support, and a push rod which is movable against a trigger device transmit, lifting! actuatable clamping device is provided.
Eine solche Armbrust ist bei1spielsweise aus dem Schweizer Patent Nr. 384409 bekannt. Das Spannen einer derartigen Hochleistungs- Armbrust erfordert eine erhebliche Kraft, weshalb speziell vorgesehene Spannvorrichtungen verwendet werden. Es sind u.a. an beiden Seiten der Armbrust fluchtend abstehende Zapfen vorgesehen, auf die eine Gabel einer heibeiartig ausgeb ldeten SpannVorrichtung aufgesetzt werden kann. Ein an dem Joch der Gabel angelenktes Stosselement greift bei Betätigung des Spannhebels an dem mit der Sehne gekuppelten Abschuss¬ schlitten an und versetzt letzteren unter Verriegelung durch die Abzugsvorrichtung in Schussbereitschaft.Such a crossbow is known, for example, from Swiss Patent No. 384409. The clamping of such a high-performance crossbow requires a considerable force, which is why specially provided clamping devices are used. There are On both sides of the crossbow protruding pins are provided, on which a fork of a heibei-shaped tensioning device can be placed. A pushing element articulated on the yoke of the fork engages the launching slide coupled to the tendon when the tensioning lever is actuated and sets the latter in readiness for firing when locked by the trigger device.
Die Benützung dieser SpannVorrichtung stellt eine schwerfällige Mani- pulierbarkeit bei der Betätigung der dafür vorgesehenen Waffe dar und erweist sich nicht in allen Fällen als zuverlässig. Dementsprechend ist die ständige Bereitstellung und Aufbewahrung einer solchen Spann¬ vorrichtung umständlich und beeinträchtigt den Schiessbetrieb. Aus der EP-A- 0041206 ist weiterhin eine Armbrust bekannt, bei der das Spannen des Bogens durch ein oberhalb des Trägers und der Pfeilfüh¬ rung vorgesehenen dreiteiligen HebelSystems bewerkstelligt werden kann.The use of this tensioning device represents a cumbersome manipulation when operating the weapon provided for this purpose and does not prove to be reliable in all cases. Accordingly, the constant provision and storage of such a tensioning device is cumbersome and impairs the shooting operation. A crossbow is also known from EP-A-0041206, in which the bow can be tensioned by means of a three-part lever system provided above the support and the arrow guide.
Mittels eines in seitl ch aus der Schl ttenfuhrung herausragende Zapfen des Abschussschlittens eingreifenden Stosselementes kann der Abschussschl tten bis zur Abzugsvorrichtung zurückgestossen und einge¬ klinkt werden. Das in einer Bohrung, d.h. aus einem Lauf beschleunigte Geschoss wird beim Abschuss durch die Spannvorrichtung nicht behindert, jedoch erfordert die Sperrigkeit des verwendenten HebelSystems auch hier ein Entfernen der SpannVorrichtung von der Armbrust. Zudem ist bei dem alternativ möglichen Abschuss von Pfeilen aus einer Rinne an der Oberseite einer Führung eine Behinderung durch die Spannvor¬ richtung kaum vermeidbar.By means of a pushing element engaging in the pin of the launching slide projecting from the slide guide, the launching slide can be pushed back as far as the triggering device and latched. That in a hole, i.e. projectile accelerated from a barrel is not hindered by the tensioning device when it is fired, however, the bulkiness of the lever system used here also requires the tensioning device to be removed from the crossbow. In addition, in the alternative possible shooting of arrows from a groove on the top of a guide, a hindrance by the tensioning device can hardly be avoided.
Bei einer Armbrust nach den vorveröffentlichten Schweizer Patenten Nrn. 43'791 und 44*542 ist eine Spannvorrichtung vorgesehen, die einen an der Unterseite des Trägers der Armbrust angeordneten durch eine Schwenkbewegung betätigbaren Spannbügel aufweist, der mit einem den Abschussschlitten in Abschussposition verschiebbaren Stossstange schwenkbar verbunden ist. Diese Spannvorrichtung lässt sich nicht im Träger der Armbrust versenken' und ist nur an der Unterseite der Waffe anbringbar. Der erforderliche grosse Raumbedarf für den Spannme¬ chanismus schwächt die Stabilität des Trägers der Armbrust bzw. zwingt zu grösserem Trägerquerschnitt und beeinträchtigt dadurch die Präzision der Waffe.In the case of a crossbow according to the previously published Swiss Patent Nos. 43'791 and 44 * 542, a tensioning device is provided which has a tensioning bracket which is arranged on the underside of the crossbow carrier and can be actuated by a pivoting movement and which is pivotably connected to a bumper which can be displaced in the firing position in the firing position is. This clamping device can not be in support of the crossbow sink 'and is attached only at the bottom of the weapon. The large amount of space required for the cocking mechanism weakens the stability of the crossbow carrier or forces the cross-section of the carrier to be larger and thereby impairs the precision of the weapon.
Die FR-A-2'373'772 macht auf eine Armbrust aufmerksam, deren Träger und Kolben an der Unterseite um eine horizontale Achse schwenkbar verbunden sind. Das Spannen des Bogens erfolgt durch eine nach unten gerichtete Schwenkbewegung des Kolbens oder Trägers, wobei am vorderen oberen Ende beidseits des Kolbens Spannstangen vorgesehen sind, die einen beim Spannen des Bogens mit dem Abschussschlitten in Verbindung bringbaren Mitnahmezapfen aufweisen. Diese hebelartige Betätigungseinrichtung erfordert aufgrund des re¬ lativ kurzen Hebelarmes eine grosse Kraftanstrengung beim Spannvorgang. Durch die Verschwenkbarkeit zwischen Kolben und Träger wird die sich auf die Schiesspräzision auswirkende Stabilität der Armbrust ungünstig beeinflusst.The FR-A-2'373'772 draws attention to a crossbow, the straps and pistons of which are pivotally connected on the underside about a horizontal axis. The bow is tensioned by a downward pivoting movement of the piston or carrier, tension rods being provided at the front upper end on both sides of the piston, which have a driving pin which can be connected to the launching slide when the bow is tensioned. Because of the relatively short lever arm, this lever-like actuating device requires a great deal of effort during the tensioning process. The stability of the crossbow, which affects the shooting precision, is adversely affected by the pivotability between the piston and the carrier.
Eine nach der US-A-3'670'711 konstruierte Armbrust besitzt eine Spann¬ vorrichtung, bei der der Spannhebel an der Unterseite schwenkbar am vorderen Ende des Kolbens angeordnet ist und die an jeder Seite des Trägers verlaufende, den Abschussschlitten mit dem Spannhebel verbindende Rückzugstangen aufweist.A crossbow constructed in accordance with US Pat. No. 3,670,711 has a tensioning device in which the tensioning lever is pivotally arranged on the underside at the front end of the piston and the one that runs on each side of the carrier and connects the launching slide with the tensioning lever Retraction bars.
Diese ausserhalb der Armbrust angebrachte Spannvorrichtung erzeugt insbesondere bei Schiessbereitschaft durch das zusätzliche Gewicht, eine den Schützen übergebührlich ermüdende Belastung.This tensioning device, which is attached outside the crossbow, creates a burden that is excessively tiring for the shooter, especially when the rifle is ready to fire due to the additional weight.
Ausgehend von den oben beanstandeten Unzulänglichkeiten und verbes¬ serungsbedürftigen Konstruktionen des Standes der Technik hat sich der Erfinder die Aufgabe gestellt, eine Armbrust nach der eingangs beschriebenen Art mit einer SpannVorrichtung zu schaffen, die einen integrierenden Bestandteil der Armbrust bildet, ein schnelleres Span¬ nen des Bogens ermöglicht und nach dem SpannVorgang so plaziert werden kann, dass durch sie das Geschoss auf seiner Bahn nicht behindert wird, die Handhabung der Armbrust nicht stört und möglichst unfauf¬ fällig in der Armbrust untergebracht werden kann.On the basis of the above-mentioned shortcomings and constructions of the state of the art in need of improvement, the inventor has set himself the task of creating a crossbow according to the type described at the outset with a tensioning device which forms an integral part of the crossbow, a faster tensioning of the crossbow This allows arches and can be placed after the tensioning process in such a way that they do not hinder the projectile on its path, do not interfere with the handling of the crossbow and can be accommodated in the crossbow as inconspicuously as possible.
Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass in der Ruhe¬ lage der Spannvorrichtung, der um eine quer zur Längserstreckung des Trägers angeordnete Horizontalachse schwenkbar gelagerte Spannhebel und das an dem Spannhebel in Schussrichtung vor dessen Schwenkachse endseitig angelenkte Stosselement unter die Pfeilschussbahn am Träger versenkbar ausgebildet sind.According to the invention, this object is achieved in that, in the rest position of the tensioning device, the tensioning lever, which is pivotably mounted about a horizontal axis arranged transversely to the longitudinal extent of the carrier, and the pushing element articulated on the end of the tensioning lever in the firing direction in front of its pivoting axis under the arrow shooting path on the carrier .
Diese Spannvorrichtuπg bietet Gewähr für einen zuverlässigen Schiessbe¬ trieb und zeichnet sich durch eine angenehme Bedienungsweise und einfachen Konstruktionsaufbau aus. Vorteilhaft zeichnet sich eine Lösung aus, wenn das am Träger lagernde Spannhebelende gabelförmig ausgebildet ist, so dass der Spannhebel an seitlich des Trägers abstehenden Zapfen oder innerhalb des Trägers gelagert werden kann, wobei er in der Ruhelage auch seitlich am Träger liegend sich erstrecken könnte.This tensioning device guarantees reliable shooting operation and is distinguished by a pleasant manner of operation and simple construction. A solution is advantageous if the tensioning lever end mounted on the support is fork-shaped, so that the tensioning lever can be mounted on pins protruding from the side of the support or within the support, and in the rest position it could also extend laterally on the support.
Alternativ könnte der Träger eine etwa mittig velaufende, den Spannhe¬ bel aufnehmende Längsnut aufweisen, wobei dann der Träger bei aussen lagernder Spannhebelgabel mit Ausnehmungen zur Durchführung letzterer versehen ist.Alternatively, the carrier could have a longitudinal groove running approximately in the middle and receiving the clamping lever, the carrier then being provided with recesses for carrying out the latter when the clamping lever fork is mounted on the outside.
Als besonders günstig erweist es sich, wenn das dem an dem Abschussschlit¬ ten angreifenden Ende gegenüberliegende Ende des Stosselementes in einer an dem Spannhebel von dessen schwenklagerseitigen Ende aus .sich längserstreckenden Ausnehmung angelenkt ist, derart, dass bei eingelegter Spannvorrichtung Spannhebel und Stosselement zumindest annähernd parallel zur Pfeilschussbahn angeordnet sind, wodurch auf einfache Weise eine anspruchslose SpannVorrichtung mit geringem Raumbe¬ darf in der Ruhelage erreicht wird.It proves to be particularly favorable if the end of the pushing element opposite the end engaging on the launching slide is articulated in a longitudinally extending recess on the tensioning lever from its end on the pivot bearing side, such that when the tensioning device is inserted, the tensioning lever and pushing element are at least approximately parallel are arranged to the arrow shooting path, whereby a simple undemanding clamping device with little space is achieved in the rest position.
Es erweist sich als vorteilhaft, wenn der Abstand zwischen der Anlenk- achse des Stosselementes an dem Spannhebel und der Schwenkachse des Spannhebels wenigstens die Hälfte der Wegstrecke des mit der Sehne verbundenen Abschussschlittens von der Abzugsvorrichtung beträgt, was eine günstige Auslegung der HebelVerhältnisse zulässt.It proves to be advantageous if the distance between the articulation axis of the pushing element on the tensioning lever and the pivot axis of the tensioning lever is at least half the distance of the launching slide connected to the tendon from the trigger device, which permits a favorable design of the lever ratios.
Die Sicherung der Spannvorrichtung gegen ein unvorhergesehenes Anheben des Spannhebels aus der Längsnut lässt sich dadurch bewerkstelligen, dass das vordere Ende des Trägers mit einer auf den versenkten Spannhe¬ bel einwirkenden Arretiervorrichtung versehen ist. Anschliessend wird die Erfindung anhand eines in der Zeichnung darge¬ stellten Ausführungsbeispieles erläutert. Es zeigen :The securing of the tensioning device against unforeseen lifting of the tensioning lever from the longitudinal groove can be accomplished in that the front end of the carrier is provided with a locking device acting on the recessed tensioning lever. The invention is then explained on the basis of an exemplary embodiment shown in the drawing. Show it :

Zum Spannen des Bogens 3 ist eine SchneiIspannvorrichtung vorgesehen, die aus einem HebelSystem mit zwei Elementen besteht, nämlich einem Spannhebel 19, der im Träger 2 um eine quer zu diesem liegende AchseFor tensioning the sheet 3, a cutting tensioning device is provided which consists of a lever system with two elements, namely a tensioning lever 19 which is in the support 2 about an axis lying transversely to the latter
20 drehbar angeordnet ist und einem Stosselement 22. Die Achse 20 liegt dabei im vorderen Teil des Schlitzes 10 des metallischen Einsatzes 5 zwischen dem Bogen 3 und dem Ruhepunkt der Sehne 4. Im unteren20 is rotatably arranged and a thrust element 22. The axis 20 lies in the front part of the slot 10 of the metallic insert 5 between the bow 3 and the point of rest of the tendon 4. In the lower
Teil ist der Spannhebel 19 mit einer sich längserstreckenden AusnehmungPart is the clamping lever 19 with an elongated recess
21 versehen, in die ein Stosselement 22 geringerer Dicke eingreift und an einem Drehpunkt 23 in einem gewissen Abstand von der Achse 20 angelenkt ist. Die Ausnehmung 21 ist dabei so bemessen, dass sie das Stosselement 22 im eingelegten Zustand der Spannvorrichtung, abgesehen von seinem freien Ende, vollständig aufzunehmen vermag. Dieses freie Ende weist eine Vertiefung 24 auf, die beim Spannvorgang in einen komplementär bzw. formschlüssig geformten Vorsprung 25 des Abzugschlittens 14 einzugreifen vermag. Bei einer Bewegung des Spannhebel 19 aus der Ruhelage gegen das hintere Ende der Armbrust wird der Abzugschlitten 14 bis zum Einklinken in den HaltebUgel 18 der Abzugvorric tung nach hinten gedrückt. Um eine einwandfreie Funktion gewährleisten zu können, muss dabei der Abstand der Achse 20 vom Drehpunkt 23 etwas mehr als die Hälfte des Spannweges des Schlittens 14 oder der Sehne 4 betragen.21, into which a thrust element 22 of smaller thickness engages and is articulated at a pivot point 23 at a certain distance from the axis 20. The recess 21 is dimensioned such that it is able to completely accommodate the push element 22 in the inserted state of the tensioning device, apart from its free end. This free end has a recess 24, which is able to engage in a complementarily or positively shaped projection 25 of the trigger slide 14 during the tensioning process. When the cocking lever 19 moves out of the rest position against the rear end of the crossbow, the trigger slide 14 is pushed back until it latches into the bracket 18 of the trigger device. In order to ensure proper functioning, the distance of the axis 20 from the pivot point 23 must be slightly more than half the span of the slide 14 or the chord 4.
Um nach Beendigung des Spannvorganges die Spannvorrichtung unauffällig und ohne Behinderung des Abschussvorganges unterbringen zu können, ist der metallische Einsatz 5 und der anschliessende Vorderteil des Trägers 2 in Fortsetzung des Schlitzes 10 für die Schlittenbewegung mit den entsprechenden Längsnutabschnitten 11,26 versehen, die so bemessen sind, dass die Spannvorrichtung beim Zurückklappen in die gestreckte Lage (Ruhestellung) zusammen mit dem in der Ausnehmung 21 des Spannhebels 19 liegenden Stosselement 22 vollständig vom Träger 2 aufgenommen wird oder gegebenenfalls nicht hindernd herausragen kann. Damit die Bewegung des Abzugschlittens 14 beim Zurückschnellen nicht behindert wird, weist der anschliessende Längsnutabschnitt 11 eine grössere Tiefe auf als der Schlitz 10 für die Schlittenführung, so dass das Stosselement 22 im zurückgeklappten Zustand vollständig unterhalb des Abzugschlittens 14 zu liegen kommt und ein Zusammenprall beim Abschuss vermieden wird.In order to be able to accommodate the tensioning device inconspicuously and without obstructing the launching process after the end of the tensioning process, the metallic insert 5 and the adjoining front part of the carrier 2, in continuation of the slot 10 for the slide movement, are provided with the corresponding longitudinal groove sections 11, 26, which are dimensioned such that the tensioning device when folded back into the extended position (rest position) together with the in the recess 21 of the clamping lever 19 lying pushing element 22 is completely received by the carrier 2 or may not protrude if necessary. So that the movement of the trigger slide 14 is not hindered when it snaps back, the subsequent longitudinal groove section 11 has a greater depth than the slot 10 for the slide guide, so that the push element 22 comes to lie completely below the trigger slide 14 in the folded-back state and a collision when fired is avoided.
Zur Vermeidung eines selbständigen Lösens der Spannvorrichtung aus der Ruhestellung, ist es zweck ässig, den Spannhebel 19 im Träger 2 zu arretieren, z.B. durch. eine am vorderen Ende des Trägers 2 vorgese¬ hene Klinke 28, die in eine Aussparung 28 am Vorderende des Spannhebels 19 einrastet. Durch einen Anschlag 29 im Längsnutabschnitt 26 kann dabei sichergestellt werden, dass das Stosselement 22 zur Gänze unter die Schlittenführung 10 gedrückt wird. Andererseits kann im hinteren Teil des tieferen Längsnutabschnittes 26 ein in Gegenrichtung wirkendes federndes Abstützelement 30 vorgesehen sein, das zu Beginn des Spann or¬ ganges das freie Ende des Stosselementes 22 so weit anhebt, dass es ohne Mühe in den Vorsprung 25 des Abzugschlittens 14 eingreift. Das Anheben des Stosselementes 22 kann dabei noch durch Anschrägen des Abzugschlittens an der Vorderseite und des Stosselementes an der Unterseite des Vorderendes erleichtert werden.To avoid an independent release of the tensioning device from the rest position, it is expedient to lock the tensioning lever 19 in the carrier 2, e.g. by. a provided at the front end of the carrier 2 pawl 28 which engages in a recess 28 at the front end of the tensioning lever 19. A stop 29 in the longitudinal groove section 26 can ensure that the push element 22 is completely pressed under the slide guide 10. On the other hand, a resilient supporting element 30 acting in the opposite direction can be provided in the rear part of the deeper longitudinal groove section 26, which at the beginning of the tensioning operation raises the free end of the pushing element 22 to such an extent that it easily engages in the projection 25 of the trigger slide 14. The lifting of the push element 22 can be made easier by chamfering the trigger slide on the front and the push element on the underside of the front end.
Alternativ kann beispielsweise der Spannhebel 19 anstatt an der Ober¬ seite mit einer Ausnehmung zur Aufnahme des Stosselementes 22 versehen zu sein, auch einen durchgehenden Schlitz aufweisen und somit als Gabel ausgebildet sein, die zusammen mit dem Stosselement in den Träger 2 versenkbar ist. Andererseits kann der Spannhebel 19 auch als massive Stange ausgeführt sein, an die das gleichfalls massiv ausgeführte Stosselement 22 seitlich angelenkt ist. Auch hier ist der Längsnutabschnitt 26 im Träger 2 so bemessen, dass er die Teile der Spannvorrichtung aufzunehmen vermag.Alternatively, for example, the tensioning lever 19, instead of being provided on the upper side with a recess for receiving the pushing element 22, can also have a continuous slot and thus be designed as a fork which can be sunk into the carrier 2 together with the pushing element. On the other hand, the clamping lever 19 can also be designed as a solid rod, to which this is also massive executed push element 22 is articulated laterally. Here, too, the longitudinal groove section 26 in the carrier 2 is dimensioned such that it can accommodate the parts of the tensioning device.
In jedem Falle kann mit den beschriebenen Spannvorrichtungen eine Armbrust besonders schnell und sehr einfach gespannt werden. Vorteilhaft ist insbesondere, dass die Armbrust durch eine Zugbewegung nach hinten gespannt werden kann, d.h. dass sie beim Spannen in Gebrauchsstellung bleibt und mit dem Kolben am Körper abgestützt werden kann, und dass die Spannvorrichtung durch einfaches Zurückklappen in eine unauffällige, nicht störene Ruhestellung gebracht werden kann. Die Handhabung der Armbrust und der SpannVorrichtung wird dadurch wesentlich erleichtert.In any case, a crossbow can be cocked particularly quickly and very easily with the clamping devices described. It is particularly advantageous that the crossbow can be stretched backwards by a pulling movement, i.e. that it remains in the use position during tensioning and can be supported on the body with the piston, and that the tensioning device can be brought into an inconspicuous, non-disturbing rest position by simply folding back. The handling of the crossbow and the tensioning device is made considerably easier.
In vorteilhafter Weiterausbildung der Erfindung kann unter Beibehaltung der bisher beschriebenen sowie abgebildeten Grundstruktur des Hebel- Systems der Spannhebel 19 etwa im Bereich seines Drehpunktes 23 unter¬ teilt sein. Im Besonderen ist hierbei der erste Hebelarm 41 des Spann¬ hebels 19 im Bereich des Drehpunktes 23 abgewinkelt und der ebenfalls abgewinkelte zweite Hebelarm 44 mit ersterem 41 durch eine quer zu beiden Hebelarmen 41,44 angeordnete gemeinsame Achse 43 gegeneinander verschwenkbar verbunden, so dass der derart unterteilte Spannhebel 19 im wesentlichen als ein an der Stelle der Achse 43 stetig abwinkel- barer, in seiner wirksamen Länge längenveränderlicher Hebel wirkt, wodurch bei seinem Einsatz die minimale Grundstruktur eines Zweihebel- systems 19, 22 gewahrt bleibt. Weil der erste Hebelarm 41 als Widerlager des anderen Hebelarmes 44 ausgebildet ist, weist der so unterteilte, längenveränderliche Spannhebel beim Spannen der Armbrust ab einer vorgebbaren Verschwenkung um die Achse 20 durch Wirksamwerden des vorgenannten Widerlagers ausserdem die starre Struktur eines einteiligen Hebels auf, jedoch mit dem weiteren Vorteil, dass beim Spannen der Armbrust durch eine veränderliche Kraftw rkung ein erleichtertes und zugleich schnelleres Spannen erreicht wird. Zur Wahrung eines günstigen Gewichtes der Armbrust mit integrierter SchnellSpannvorrichtung, besteht die im dargestellten Beispiel aus dem Kolben 1 und dem Träger 2 gebildete, fast alle Armbrustteile tragende Einheit aus wenigstens einem nicht metallischen Werkstoff, wie Holz oder Kunststoff. Die im Kraftschluss zusammenwirkenden Teile zwischen Bogen 3 und Achse 20 sind in einem mechanisch hochbelastbaren metallischen Einsatz 5 der vorgenannten Einheit angeordnet, um die Armbrust bei möglichst geringem Gesamtgewicht intensiv beanspruchen zu können. Zur Sicherstellung einer hohen Beanspruchbarkeit des Erfin¬ dungsgegenstandes bei gleichzeitiger Erhaltung der Präzision, ist es von besonderem Vorteil, wenn das aus dem Kolben 1 und dem Träger 2 bestehende, die intergrierte SchnellspannVorrichtung mittragende System aus nur einem Werkstoff, beispielsweise einem Verbundstoff aus verschiedenen Komponenten, oder auch aus einem Metall hergestellt wird.In an advantageous further development of the invention, the clamping lever 19 can be subdivided approximately in the region of its pivot point 23 while maintaining the basic structure of the lever system described and illustrated so far. In particular, the first lever arm 41 of the tensioning lever 19 is angled in the region of the pivot point 23 and the likewise angled second lever arm 44 is pivotally connected to the former 41 by a common axis 43 arranged transversely to both lever arms 41, 44, so that the latter subdivided tensioning lever 19 essentially acts as a lever that can be bent continuously at the location of the axis 43 and that is length-variable in its effective length, as a result of which the minimal basic structure of a two-lever system 19, 22 is maintained when it is used. Because the first lever arm 41 is designed as an abutment of the other lever arm 44, the length-adjustable tensioning lever divided in this way has the rigid structure of a one-piece lever when the crossbow is tensioned from a predeterminable pivoting about the axis 20 by the aforementioned abutment taking effect, but with the Another advantage is that easier and faster cocking is achieved when the crossbow is cocked due to a variable force. In order to maintain a favorable weight of the crossbow with an integrated quick-release device, the unit formed in the example shown, consisting of the piston 1 and the carrier 2, which carries almost all crossbow parts, consists of at least one non-metallic material, such as wood or plastic. The parts interacting in the frictional connection between the bow 3 and the axis 20 are arranged in a mechanically heavy-duty metallic insert 5 of the aforementioned unit in order to be able to intensively stress the crossbow with the lowest possible overall weight. In order to ensure that the object of the invention can be subjected to high loads while at the same time maintaining precision, it is particularly advantageous if the system consisting of the piston 1 and the carrier 2 and carrying the integrated quick-action clamping device is made of only one material, for example a composite of different components. or is also made of a metal.
Die Armbrust nach der Erfindung weist bei umfassender Integration der SchnellSpannvorrichtung die Raumform einer vermeintlich Spannvorrich¬ tungsfreien Armbrust auf.The crossbow according to the invention has the spatial shape of a supposedly non-tensioning crossbow with extensive integration of the quick-release device.
Kurz zusammengefasst zeichnet sich die Erfindung bei einer geringen Anzahl an Teilen für die integrierte SchnellSpannvorrichtung durch einfaches und sicheres Zusammenwirken der erforderlichen Teile aus. In a nutshell, the invention is characterized by a small number of parts for the integrated quick-action clamping device by simple and safe interaction of the required parts.
