Abstract

An implement for heavy athletics comprises a supporting frame, a tensile element, which is provided with a handle and adapted to be extended against a restoring force, and an instrument for measuring the tensile force exerted on the handle. To permit an exact measurement and the provision of a tensile force-displacement characteristic which is or can be exactly adapted to a given sport, the tensile force is measured by means of an electronic force pick-up, which comprises a force-measuring sensor and is combined with a digital display device. The force-measuring sensor is connected to the handle by means of the tensile element, and the tensile element is extensible against a resistance having a predetermined characteristic.

Description

Die Erfindung betrifft ein neues Kraftsportgerät nach dem einleitenden Teil des Patentanspruches 1.The invention relates to a new weight training device according to the introductory part of patent claim 1.

Insbesondere betrifft die Erfindung ein Kraftsportgerät, das sich als Trainings- und Wettkampfgerät für Wettkämpfe mit folkloristischem Einschlag, vor allem das sogenannte Fingerhakeln, eignet.In particular, the invention relates to a weight training device that is suitable as a training and competition device for competitions with a folkloristic touch, especially the so-called finger hooking.

Ein Kraftsportgerät nach dem einleitenden Teil des Anspruches 1 ist aus der GB-A-2094647 bekannt. Es handelt sich dabei um ein Trainingsgerät, bei dem ein Seil mittels einer Handhabe aus einem Gehäuse gegen einen einstellbaren Widerstand herausziehbar ist, wobei die eingestellte Widerstandskraft sowie die Zeitdauer, für die diese Widerstandskraft überwunden wurde, angezeigt werden. Um dies zu erreichen, ist das Seil im Gehäuse auf eine Trommel aufgewickelt, die von einem Motor über ein Zwischengetriebe mit einstellbarem Drehmoment angetrieben wird, wobei das Drehmoment an verschiedene durchzuführende Übungen angepasst werden kann. Die gegen das aufgebrachte Drehmoment aufgewendete Zugkraft und das Ausmass, um das das Zugglied aus dem Gehäuse herausgezogen wird, werden durch Wegemesseinrichtungen mit beispielsweise am Trommelumfang vorgesehenen Fühlern oder photoelektrischer Abtastung erfasst und angezeigt. Es ist möglich, das vom Motor aufgebrachte Drehmoment über eine Programmsteuereinrichtung zu variieren. Es erfolgt keine unmittelbare Kraftmessung, sondern diese Kraftmessung wird aufwendig auf dem Umweg über die Wegemessung und die Erfassung der eingegebenen charakteristischen Daten des über den Motor aufgebrachten Drehmomentes bewerkstelligt. Es lässt sich praktisch keine individuell mögliche Höchstleistung bestimmen, sondern nur ermitteln, ob ein vorgegebener Widerstand überwunden wurde oder nicht.A weight training device according to the introductory part of claim 1 is known from GB-A-2094647. It is a training device in which a rope can be pulled out of a housing against an adjustable resistance by means of a handle, the resistance being set and the time for which this resistance has been overcome being displayed. To achieve this, the rope in the housing is wound on a drum which is driven by a motor via an intermediate gear with adjustable torque, the torque being adaptable to various exercises to be carried out. The tensile force exerted against the applied torque and the extent to which the tension member is pulled out of the housing are detected and displayed by path measuring devices with sensors or photoelectric scanning provided on the drum circumference, for example. It is possible to vary the torque applied by the engine using a program control device. There is no direct force measurement, but this force measurement is carried out in a complex manner on the detour via the distance measurement and the acquisition of the entered characteristic data of the torque applied via the motor. It is practically impossible to determine an individually possible maximum performance, but only to determine whether a given resistance has been overcome or not.

Aus der DE-A-21 57949 ist eine Messeinrichtung für Schwimmleistungen bekannt, mit deren Hilfe die von einem Schwimmer mittels eines Gurtes auf ein Seil übertragene Zugkraft und die Dauer der Aufbringung einer bestimmten Mindestzugkraft auf das Seil gemessen werden. Zu diesem Zweck ist das Seil in ein Gehäuse geführt und dort mit einem rotierend antreibbaren Drehkörper verbunden, der seinerseits im Gehäuse gegen eine Feder verstellbar ist und von einem Uhrwerk angetrieben wird. Der Drehkörper besitzt ein gegebenenfalls gewölbtes, konisches Endstück mit dem ein Fühlerrad in Eingriff steht. Über ein weiteres Fühlerrad wird die normale Drehzahl des Drehkörpers erfasst. Beide Fühlerräder sind mit je einem Zählwerk verbunden, so dass das eine Zählwerk, das die Zahl der Umdrehungen erfasst, die Dauer der Schwimmübung angibt und das andere Zählwerk einen dem Ausziehen des Drehkörpers gegen die Feder und damit der aufgebrachten Kraft während der gewählten Zeitdauer entsprechenden Zählwert angibt. Es werden sportliche Dauerleistungen gemessen. Eine Erfassung momentaner Spitzenleistungen ist nicht möglich.From DE-A-21 57949 a measuring device for swimming performance is known, with the help of which the tensile force transmitted by a swimmer by means of a belt to a rope and the duration of the application of a certain minimum tensile force to the rope are measured. For this purpose, the rope is guided into a housing and there connected to a rotating drivable rotating body, which in turn is adjustable against a spring in the housing and is driven by a clockwork. The rotating body has an optionally curved, conical end piece with which a sensor wheel is engaged. The normal speed of the rotating body is recorded via another sensor wheel. Both feeler wheels are connected to a counter, so that one counter, which records the number of revolutions, indicates the duration of the swimming exercise and the other counter indicates a counter value corresponding to the extension of the rotating body against the spring and thus the applied force during the selected period indicates. Continuous sporting performances are measured. It is not possible to record current peak performance.

Aus der DE-A-15 78 648 ist ein Trainingsgerät bekannt, das eine dem Gewichtheben ähnliche körperliche Betätigung ermöglichen soll. Bei diesem Gerät kann ein Seil, das durch eine Reibungsbremse gebremst wird, aus einem Haltegestell herausgezogen werden. Die auf das Seil ausgeübte Bremskraft ist nach einer Skala einstellbar. Eine exakte Bestimmung der tatsächlich aufgebrachten Zugkraft oder eines Maximalwertes der Zugkraft ist nicht möglich.From DE-A-15 78 648 a training device is known which is intended to enable physical exercise similar to weight lifting. With this device, a rope that is braked by a friction brake can be pulled out of a holding frame. The braking force exerted on the rope can be adjusted on a scale. It is not possible to determine the actual tensile force actually applied or a maximum value of the tensile force.

Aus der DE-A-14 78 056 ist ein Gerät zum Muskeltraining bekannt, bei dem ein Teil von Hand aus entlang einer durch eine Schienenführung bestimmten Bahn bewegt werden muss, wobei die Geschwindigkeit, mit der der Teil bewegt werden kann, nach einer Skala einstellbar ist. Auf den Teil wirkt zusätzlich ein motorischer Antrieb. Die von ihm aufgebrachte Kraft und die aufgewendete Muskelkraft überlagern sich am bewegten Teil und auf einer Anzeige wird die Differenz zwischen der durch die Überlagerung erzeugten Gesamtkraft und der messbaren Motorkraft als tatsächlich aufgewendete Muskelkraft angezeigt. Ein wettkampfmässiger Einsatz des Kraftsportgerätes ist nicht möglich bzw. vorgesehen.From DE-A-14 78 056 a device for muscle training is known, in which a part has to be moved manually along a path determined by a rail guide, the speed at which the part can be moved being adjustable on a scale is. A motor drive also acts on the part. The force applied by him and the muscle power applied overlap on the moving part and the display shows the difference between the total force generated by the overlay and the measurable motor power as the actual muscle power applied. A competitive use of the weight training device is not possible or intended.

Es gibt Geräte zum Muskeltraining, insbesondere zum Training der Hand- und Armmuskeln in der Grundform einer Drehfeder, deren beide aus einem Gehäuse herausgeführte Endschenkel erfasst und aufeinander zu bewegt werden müssen. Der eine Schenkel der Drehfeder ist am Gehäuse festgelegt und der andere Schenkel bildet gleichzeitig einen entlang einer Gehäuseskala verstellbaren Zeiger, so dass die im Sinne des Zusammendrückens auf die beiden Federschenkel ausgeübte Kraft grob angezeigt werden kann. Es ist aber keine objektive Kraftmessung und auch keine Erfassung des exakten Maximalwertes einer aufgebrachten Kraft möglich.There are devices for muscle training, in particular for training the hand and arm muscles in the basic form of a torsion spring, the two end legs of which have to be gripped out of a housing and must be moved towards one another. One leg of the torsion spring is fixed to the housing and the other leg simultaneously forms a pointer that can be adjusted along a housing scale, so that the force exerted on the two spring legs in the sense of compression can be roughly displayed. However, no objective force measurement and also no detection of the exact maximum value of a force applied is possible.

Die US-A-4307608 betrifft ein Gerät zur Erfassung der Muskelkraft, das im wesentlichen aus einer Kraftmessdose besteht, die mit zwei Handgriffen versehen ist, über die wahlweise Zug- oder Druckkräfte auf den Kraftmessfühler übertragen werden, von dem aus eine digitale Anzeigevorrichtung für die aufgebrachte Kraft gesteuert wird, wobei diese Anzeigevorrichtung auch Einrichtungen zur Erfassung des Maximalwertes der aufgewendeten Kraft und zum Rücksetzen der Anzeige enthalten kann. Die Kräfte werden mit beiden Händen gegensinnig aufgebracht. Es kann daher in der Praxis nur die Kraft der schwächeren Hand gemessen werden. Die Kraftmessdose hat einen vernachlässigbar kleinen Messweg, so dass kein für die meisten Sportarten typischer Kraft/Wegverlauf vorgebbar ist.US-A-4307608 relates to a device for detecting muscle strength, which consists essentially of a load cell, which is provided with two handles, via which tensile or compressive forces are transmitted to the force sensor, from which a digital display device for the applied force is controlled, and this display device can also contain devices for detecting the maximum value of the force applied and for resetting the display. The forces are applied in opposite directions with both hands. In practice, therefore, only the strength of the weaker hand can be measured. The load cell has a negligibly small measuring path, so that no force / path characteristic that is typical for most sports can be specified.

Bei den bekannten Kraftsportgeräten erfolgt daher, wenn ein Kraft-Wegverlauf im Gerät vorgegeben ist, die Kraftmessung auf dem Umweg einer Wegmessung gegen einen von aussen aufgebrachten Widerstand bzw. auf dem Umweg der Leistungsmessung eines zusätzlich benötigten Antriebsmotors. Bei reinen Kraftmessgeräten wie nach der US-A-4307608 ist keine Anpassung an den Kraftaufwand-Bewegungsablauf bekannter Sportarten möglich bzw. vorgesehen.In the known strength-training devices, therefore, if a force-displacement curve is specified in the device, the force measurement is carried out by detouring a displacement measurement against an externally applied resistance or by detouring the power measurement of an additionally required drive motor. With pure force measuring devices such as according to US-A-4307608, no adaptation to the force-movement sequence of known sports is possible or provided.

Aufgabe der Erfindung ist die Schaffung eines neuen Kraftsportgerätes, das einfach aufgebaut ist, eine direkte Messung der aufgebrachten Kräfte ermöglicht und dabei trotzdem an die Bewegungsabläufe bei verschiedenen Sportarten angepasst werden kann. Die Hauptaufgabe der Erfindung besteht in der Schaffung eines Kraftsportgerätes, welches bei dem als Fingerhakeln bekannten Kraftsport mit folkloristischem Einschlag genaue Messungen der von den Wettkämpfern erbrachten Leistungen unter gleichen Bedingungen ermöglicht und dabei trotzdem dem einzelnen Wettkämpfer ähnliche Bedingungen bietet, wie sie beim tatsächlichen Wettkampf gegen einen Gegner vorhanden sind.The object of the invention is to create a new weight training device which is simple in construction, enables direct measurement of the forces applied and yet can be adapted to the movement sequences in various sports. The main object of the invention is to provide a weight training device which in the weightlifting sport with folkloric streak known as finger-hooking enables accurate measurements of the services provided by the competitors under the same conditions and still offers the individual competitors similar conditions to those that exist in actual competition against an opponent.

Bei einem tatsächlichen Wettkampf beim Fingerhakeln sitzen die beiden Wettkämpfer einander auf Schemeln an einem stabilen Tisch gegenüber, haken die Mittelfinger der einen Hand unmittelbar ineinander oder in eine gemeinsame kurze Lederschlaufe, den sogenannten Zugriemen ein und haben die Aufgabe, die Hand des Gegners bis über eine vorbestimmte Marke, meist den eigenen Tischrand zu ziehen.In an actual finger-hooking competition, the two competitors sit opposite each other on stools at a stable table, hook the middle fingers of one hand directly into one another or into a short leather strap, the so-called pull strap, and have the task of holding the opponent's hand up to one predetermined brand, usually to draw your own table edge.

Die gestellte Aufgabe wird mit den Merkmalen des kennzeichnenden Teiles des Patentanspruches 1 gelöst.The object is achieved with the features of the characterizing part of patent claim 1.

Es wird eine elektronische Kraftmesseinrichtung zur unmittelbaren Kraftmessung verwendet; obwohl in der Regel diese Kraftmesseinrichtung einen vernachlässigbar kleinen Messweg aufweist, wird der Kraft-Wegverlauf bei der Ausübung einer bestimmten Sportart über die Zugfeder und deren Charakteristik angepasst. Beim Fingerhakeln wird die Handhabe meist als Haken zum Einhängen eines Zugriemens ausgebildet, kann aber auch unmittelbar statt des Mittelfingers des Konkurrenten erfasst werden. Die zum Ausziehen der Handhabe über dem Tisch gegen die Feder aufgewendete Kraft wird unmittelbar gemessen und angezeigt. Die Ausziehweite des Zuggliedes und der Widerstand, den das Zugglied dem Ausziehen entgegensetzt, können den tatsächlichen Verhältnissen angepasst sein. Die Messeinrichtungen können Kraftmessdosen mit Dehnungsmessstreifen oder piezoelektrischen Fühlern sein. Durch die Ausbildung mit der Anordnung eines Stützgestelles auf einer vor dem Tisch eine Stellfläche aufweisenden Stützplatte wird die Aufstellung eines Schemels auf dieser Stützplatte möglich. Das Gerät kann an beliebiger Stelle aufgestellt werden, ohne dass für das Stützgestell eine Bodenverankerung notwendig wird, weil sich die vom Wettkämpfer aufgebrachten Kräfte bezüglich der Stützplatte gegenseitig aufheben.An electronic force measuring device is used for direct force measurement; Although this force measuring device generally has a negligibly small measuring path, the force-path curve is adjusted when a certain sport is practiced via the tension spring and its characteristics. In the case of finger hooking, the handle is usually designed as a hook for hanging a pull strap, but can also be grasped directly instead of the competitor's middle finger. The force exerted against the spring to pull out the handle above the table is measured and displayed immediately. The extension distance of the tension member and the resistance that the tension member opposes to the extension can be adapted to the actual conditions. The measuring devices can be load cells with strain gauges or piezoelectric sensors. The design with the arrangement of a support frame on a support plate having a footprint in front of the table makes it possible to set up a stool on this support plate. The device can be set up at any point without anchoring to the floor being necessary because the forces exerted by the competitor on the support plate cancel each other out.

Durch die schwenkbare Lagerung des Gehäuses nach Anspruch 2 die sowohl um eine horizontale, parallel zur Tischebene verlaufende Achse als auch um eine senkrechte Achse möglich ist, stellt sich das Gehäuse mit dem Zugglied in die jeweilige Zugrichtung ein, so dass die tatsächlich aufgwendete Kraft und nicht nur die entsprechende Komponente bei einem sonst möglichen Winkel zwischen Zug- und Ausziehrichtung gemessen werden. Die vorgesehene Feder kann als mechanische oder pneumatische Feder ausgeführt sein. Durch die Dämpfungseinrichtung nach Anspruch 3 wird eine bessere Anpassung an die bei den meisten Sportarten tatsächlich herrschenden Wettkampfbedingungen erzielt und auch die Verletzungsgefahr für den Wettkämpfer durch ein nach völliger oder teilweiser Freigabe der Handhabe zurückschnellendes Zugglied verhindert. Eine bevorzugte Ausführung der Dämpfungseinrichtung ist in Anspruch 4 angegeben.Due to the pivotable mounting of the housing according to claim 2, which is possible both about a horizontal axis running parallel to the table plane and about a vertical axis, the housing adjusts itself with the tension member in the respective direction of tension, so that the force actually used and not only the corresponding component can be measured at an otherwise possible angle between the pulling and pulling directions. The spring provided can be designed as a mechanical or pneumatic spring. By the damping device according to claim 3, a better adaptation to the competition conditions actually prevailing in most sports is achieved and also the risk of injury to the competitor is prevented by a pulling member that snaps back after complete or partial release of the handle. A preferred embodiment of the damping device is specified in claim 4.

Die Ausbildung nach Anspruch 5 ermöglicht die Anzeige der höchsten von einem Wettkämpfer aufgebrachten Zugkraft. Die Anzeige kann stehenbleiben bzw. über eine eigene Löschtaste oder ein Zeitglied löschbar sein. Es ist auch eine Ausführung nach Anspruch 6 möglich, um etwa jeweils bestehende Rekorde an einem Trainingsgerät auf Dauer festzuhalten.The embodiment according to claim 5 enables the display of the highest pulling force exerted by a competitor. The display can stop or can be deleted using its own delete key or a timer. An embodiment according to claim 6 is also possible in order to permanently hold any existing records on a training device.

Bei entsprechender Adaptierung kann das Kraftsportgerät auch für andere Kraftsportarten eingesetzt werden. Für das «Armdrücken» kann man am Tisch einen Schwenkhebel lagern, der die Hand der Gegners darstellen soll und der mit dem Zugglied in Verbindung steht.With appropriate adaptation, the weight training device can also be used for other strength sports. For «arm wrestling», a swivel lever can be placed on the table, which should represent the opponent's hand and which is connected to the tension member.

Nach Fig. 1 ist das Gerät für das «Fingerhakeln» bestimmt. Dementsprechend ist ein Fingerhaklertisch 1 vorgesehen, der neben einem Stützgestell 2 auf einer Stützplatte 3 montiert ist, die vor dem Tisch 1 Platz zum losen Aufstellen eines Schemels 4 bietet. Auf diesem Schemel 4 nimmt ein Wettkämpfer Platz. Das Stützstell 2 befindet sich an der gegenüberliegenden Seite des Tisches 1, es trägt erhöht über der Tischplatte 5 eine elektronische Anzeigevorrichtung 6, die mit ihrem Anzeigefeld zur freien Tischseite weist.According to Fig. 1, the device is intended for "finger hooking". Accordingly, a finger hooking table 1 is provided, which is mounted next to a support frame 2 on a support plate 3, which offers 1 space in front of the table for loosely placing a stool 4. A competitor sits on this stool 4. The support point 2 is located on the opposite side of the table 1, it carries an electronic display device 6 elevated above the table top 5, which points with its display field to the free table side.

Oberhalb der Tischplatte ist am Stützgestell 2 um eine horizontale Querachse 7 ein Gehäuse 8 schwenkbar gelagert, aus dem ein eine Handhabe darstellender Zughaken 9 herausgeführt ist. Der Wettkämpfer hängt einen Zugriemen 10 in den Zughaken 9 ein und hakt seinen Mittelfinger in diesen Zugriemen 10. Die vom Wettkämpfer aufgebrachte Zugkraft wird elektronisch erfasst und auf der Anzeige 6 angezeigt. Der Wettkämpfer kann mit seinem Mittelfinger etwas höher oder tiefer am Zugriemen 10 angreifen als dies der Lage des Hakens 9 in Fig. 1 entspricht. Das Gehäuse 8 wird um die Achse 7 schwenken, so dass sich eine im Gehäuse 8 in einer Buchse 11 geführte Führungsstange 12 des Zughakens 9 jeweils in die Richtung des aufgewendeten Zuges einstellt.Above the table top, a housing 8 is pivotally mounted on the support frame 2 about a horizontal transverse axis 7, from which a pulling hook 9 representing a handle is led out. The competitor hangs a pull strap 10 into the pull hook 9 and hooks his middle finger into this pull strap 10. The pulling force exerted by the competitor is recorded electronically and displayed on the display 6. The competitor can attack with the middle finger slightly higher or lower on the strap 10 than this corresponds to the position of the hook 9 in FIG. 1. The housing 8 will pivot about the axis 7, so that a guide rod 12 of the pull hook 9, which is guided in the housing 8 in a bush 11, adjusts itself in the direction of the train used.

Nach Fig. 2 ist die Führungsstange 12 über eine Zugfeder 13 und ein bei entspannter Zugfeder schlaffes Drahtseil 14, das über eine weitere Feder 15 in einer Buchse 16 abgestützt ist, mit dieser Buchse 16 verbunden. Die Buchse 16 ist durch eine eine Bohrung 17 in einem Stützrahmen 18 durchsetzende Schraube 19 mit einem Endstück 20 einer Kraftmessdose 21 verbunden, die ihrerseits mit einem weiteren Endstück 22 innerhalb des Gehäuses 9 an einem Stützrahmen 23 abgestützt ist. Die Kraftmessdose 21 erzeugt abhängig von der auf das Endstück 20 wirkenden Kraft veränderliche elektrische Grössen, die elektronisch ausgewertet werden können. Insbesondere enthält die Kraftmessdose Widerstands-Dehnungsmessstreifen die dann in einer Messbrückenschaltung liegen, oder Piezoelemente.2, the guide rod 12 is connected to this socket 16 via a tension spring 13 and a slack wire rope 14 when relaxed, which is supported in a socket 16 by a further spring 15. The bushing 16 is connected by a screw 19 passing through a bore 17 in a support frame 18 to an end piece 20 of a load cell 21, which in turn is supported by a further end piece 22 within the housing 9 on a support frame 23. Depending on the force acting on the end piece 20, the load cell 21 generates variable electrical quantities which can be evaluated electronically nen. In particular, the load cell contains resistance strain gauges which are then in a measuring bridge circuit, or piezo elements.

Bei der Ausführung nach Fig. 3 sind an Stelle des Seiles 14 und der Feder 15 nach Fig. 2 zwischen der Führungsstange 12 und der Buchse 16 innerhalb der Feder 13 die Verstellgeschwindigkeit in beiden Richtungen begrenzende Dämpfungseinrichtungen angebracht. Beim Ausführungsbeispiel ist ein mit einem hydraulischen Mittel gefüllter Zylinder 24 vorgesehen, der mit der Buchse 16 verbunden ist. Aus dem Zylinder 24 ist abgedichtet eine mit der Führungsstange 10 verbundene Kolbenstange 25 herausgeführt, die einen im Zylinder 24 verstellbaren Kolben 26 trägt, der eine einen im Verhältnis zum Zylinderquerschnitt kleinen Querschnitt aufweisende Durchtrittsöffnung 27 besitzt. Die Verstellgeschwindigkeit des Kolbens 26 und damit die Ausziehgeschwindigkeit des Hakens 7 wird, ebenso wie das Zusammenziehen der vorher gespannten Feder 13 nach Freigabe des Hakens durch den Dämpfer 24 bis 27 gebremst. Man könnte auch eine etwas grössere Öffnung 27 mit einer sich bei der Rückstellbewegung schliessenden, eine kleinere Durchtrittsöffnung aufweisenden Klappe od. dgl. vorsehen, um für das Ausziehen und Zurückziehen verschiedene Dämpfungswerte zu erhalten.In the embodiment according to FIG. 3, instead of the cable 14 and the spring 15 according to FIG. 2, between the guide rod 12 and the bush 16 within the spring 13 the damping devices limiting the adjustment speed are attached in both directions. In the exemplary embodiment, a cylinder 24 is provided which is filled with a hydraulic medium and is connected to the bushing 16. A piston rod 25 connected to the guide rod 10 is sealed out of the cylinder 24 and carries a piston 26 which is adjustable in the cylinder 24 and which has a passage opening 27 which is small in relation to the cylinder cross section. The adjustment speed of the piston 26 and thus the pull-out speed of the hook 7, like the contraction of the previously tensioned spring 13, is braked by the damper 24 to 27 after the hook is released. One could also provide a somewhat larger opening 27 with a flap or the like which closes during the return movement and has a smaller passage opening, in order to obtain different damping values for the extension and retraction.

Wie Fig. 4 zeigt, liegt der elektronische Ausgang der Kraftmessdose 21 an einem Messverstärker 28, dem ein Analog-Digitalwandler 29 nachgeordnet ist. Dieser legt einen dem jeweiligen absoluten Messwert entsprechenden Digitalwert auf einen Mikroprozessor 30, der über eine Anzeige-Steuereinrichtung 31 und einen Decoder-Treiber 32 die elektronische Anzeigeeinrichtung 6 steuert, so dass dort die auf den Haken 9 wirkende Zugkraft bzw. die bei einem Versuch auftretende maximale Zugkraft angezeigt wird.As shown in FIG. 4, the electronic output of the load cell 21 is connected to a measuring amplifier 28, which is followed by an analog-digital converter 29. This places a digital value corresponding to the respective absolute measured value on a microprocessor 30, which controls the electronic display device 6 via a display control device 31 and a decoder driver 32, so that there the tensile force acting on the hook 9 or that occurring during a test maximum pulling force is displayed.
