Description

Die Erfindung betrifft einen als Muskelstärker zu verwendenden Kraftstab, welcher ähnlichen Apparaten gegenüber den Vorzug hat, daß er neben einer einfacheren und billigeren 'Konstruktion kein Kippmoment besitzt, welches bei anderen derartigen Apparaten eintritt, sobald die auf die Hiebe! ausgeübten Knäfte ungleich sind.The invention relates to a strength rod to be used as a muscle strengthener, which It has the advantage over similar apparatus that it is in addition to a simpler and cheaper one '' Construction has no overturning moment, which occurs with other such devices, as soon as the blows! the forces exercised are unequal.

Die 'Zeichnung stellt einen solchen Kraftto stab in einer Längsansicht dar.The 'drawing shows such a power unit in a longitudinal view.

Zwei Handhebel a, b sind an ihren Enden bei c durch, einen Bolzen drehbar verbunden. Zwischen dieser Verbindung sitzt, ebenfalls beweglich, auf dem Bolzene ein Verbindungs- stückd. In den Löcherne,e oder ./,/ dieses Verbindungsstückes d sind Zugfedern k, k eingehakt, Welche mit ihren anderen Enden in den Löchern h, h oder i,i der an den Hebeln befestigten Halter £, g eingehakt sind,
ao Die Wirkungsweise des Kraftstabes ist folgende: Two hand levers a, b are rotatably connected at their ends at c by a bolt. A connecting piece d is seated between this connection, also movably, on the bolt. Tension springs k, k are hooked into the holes e, e or ./,/ of this connecting piece d , the other ends of which are hooked into the holes h, h or i, i of the holders £, g attached to the levers,
ao The mode of action of the power rod is as follows:

Schwingt man die Hebelenden nach unten zusammen, so beschreiben die Enden der Federn bei h,h oder i,i um den Drehpunkte »5 größere Kreise von ihren Anfangspunkten bei h, h oder i, i ab als wie von diesen Punkten ausgehend um die Drehpunkte der Federenden bei e,e oder /,/.If you swing the lever ends downwards together, the ends of the springs at h, h or i, i around the pivot point »5 describe larger circles from their starting points at h, h or i, i than around the pivot points starting from these points of the spring ends at e, e or /, /.

Die Differenz der Radien dieser Kreiskurven ist die Strecke x-y, um welche die Zugfedern oder andere zwischengeschaltete elastische Widerstände ausgedehnt werden.
Je Weiter man die Löcher für die Federhaltungen im Verbindungsstück d von c absetzt, desto größer wird die Differenz der Radien Ond desto stärker der elastische Widerstand des Kraftstabes sein. Das Verbindungsstück«? hat ferner den Zweck, die Wirkungen 'ungleicher Federn auszugleichen.The difference in the radii of these circular curves is the distance xy by which the tension springs or other intermediate elastic resistances are extended.
The further you move the holes for the spring mounts in the connector d from c , the greater the difference in the radii Ond the greater the elastic resistance of the force rod. The connecting piece «? also has the purpose of compensating for the effects of unequal springs.

Patentanspruch:Claim: Kraftübungsstab, dadurch gekennzeichnet, daß zwei um einen gemeinsamen Drehpunkt (c) schwingende Hebel (a, b) ■ Zugfedern (k, k) o. dgl. tragen, welche am Drehpunkt (c) 'der Hebel vermittels eines um 'den, gleichen Drehpunkt (c) schwingbaren Verbindungsstückes (d) o. dgl. miteinander verbunden sind, so daß sie entsprechend 'der Differenz der verschiedenen Radienlängen, welche beim Schwingen der Hebel 1Um ihren gemeinsamen Drehpunkt (c) durch das gleichzeitige Schwingen der Federenden um ihre aus dem gemeinsamen Hebeldrehpunkt (c) herausfallenden Drehungsmittelpunkte [e, e bzw. /, /), also auf ungleich großen Kreisen wie um den Punkt (c und e, e oder /, /) entsteht, gespannt werden, wobei dier Spannungswiderstand durch. Versetzen der Löcher (e, e) im Stück (d) vom Drehpunkt Strength exercise bar, characterized in that two levers (a, b ) swinging around a common pivot point (c) ■ carry tension springs (k, k) or the like, which at the pivot point (c) 'of the lever by means of a' the, same pivot point (c) swingable connecting piece (d) or the like. Are connected to each other, so that they according to 'the difference of the different radius lengths, which when swinging the lever 1 to their common pivot point (c) by the simultaneous swinging of the spring ends around their centers of rotation [e, e or /, /) falling out of the common fulcrum (c), i.e. on circles of unequal size as arises around the point (c and e, e or /, /), are tensioned, whereby the tension resistance through. Offset the holes (e, e) in the piece (d) from the pivot point (c) ab sich verstärkt und ferner ein etwaiger Spannungsunterschied in den Federn durch das schwingbare Verbindungsstück (c) ab increases and further any difference in tension in the springs due to the oscillating connector (d) ausgeglichen wird. (d) is balanced.
