Abstract
Description
SEITENSTÜTZE FÜR HAUSHALTSLEITERN LATERAL SUPPORT FOR HOUSEHOLD MANAGERS
Viele Unfälle im Haushalt werden durch umstürzende Leitern verursacht, weil die Aufstandsfläche durch die vier Holme begrenzt wird und bei einer Verlagerung des Schwerpunktes über die Auf standsflächengrenze die Leiter mit der darauf befindlichen Person umfällt.Many household accidents are caused by ladders falling over, because the contact area is limited by the four spars and in the event of a shift of the center of gravity over the footprint boundary, the ladder with the one on it Person falls over.
Die Erfindung betrifft die Herstellung einer größeren seitlichen Aufstandsfläche durch Anbringen an einer oder beiden Seitenholmen im oberen Teil festangebrachten und drehbaren und schwenkbaren Stütze, deren Länge etwas kürzer als der Trittholm ist, sind einen rutschfesten Fuß besitzt.The invention relates to the production of a larger lateral contact area fixed by attaching to one or both side rails in the upper part and rotatable and swiveling support, the length of which is slightly shorter than the step bar are have a non-slip foot.
Beim Aufstellen der Leiter spreizen sich die Leiterholme in einem bestimmten Winkel. Dadurch wird die schwenkbar angebrachte Stütze in einem Kreisbogen nach außen mit ihrem Fußpunkt zum anderen Holm geführt und in einem ausreichend entfernten Punkt durch einen am unteren Ende angebrachten schwenkbaren Haltearm mit einer öse am Trittholm arretiert. Bodenunebenheiten werden durch Radiusabweichungen ausgeglichen. Zum anderen Holm wird mittels einer Kette, eines Hebels mit Längenverstellung, oder anderer geeigneter Halteteile festgelegt. Die Seitenstütze steht damit fest am Boden. Die Leiter kann nun nach beiden und/oder einer Seite weit hinaus belastet werden, ohne umzufallen.When the ladder is set up, the ladder stiles expand in one certain angle. As a result, the pivotably attached support is in an arc of a circle outwards with its foot point to the other spar and in one sufficient distant point by a pivoting arm attached to the lower end locked with an eyelet on the step bar. Uneven floors are caused by deviations in the radius balanced. On the other hand, a chain, a lever with length adjustment, or other suitable holding parts. The side support is now in place on the ground. The ladder can now be loaded far out on both and / or one side without falling over.
Diese Stützen sind schon ab Fabrik bei neuen Leitern oder auch bei vorhandenen Leitern im Haushalt nachträglich anzubringen.These supports are already at the factory with new ladders or with to retrofit existing ladders in the household.
Die Skizze 1 zeigt eine übliche Haushalts leiter in der Ansicht von oben und in Skizze 2 in der Perspektive.Sketch 1 shows a typical household ladder in the view of above and in sketch 2 in perspective.
Die vier Holme (a) mit den Stufen (b), den zwei zusätzlichen Seitenstützen (c) und den festen Drehpunkten (d) an den Trittholmen, sowie dem Schwenkkreis (e), der sich aus dem Offnungswinkel der Holmpaare ergibt. Die schwenkbaren Arretierungsstangen (f) mit den Halteketten (g) garantieren den festen Stand der Stützen.The four spars (a) with the steps (b), the two additional side supports (c) and the fixed pivot points (d) on the step bars, as well as the swivel circle (e), which results from the opening angle of the spar pairs. The pivoting locking bars (f) with the retaining chains (g) guarantee that the supports are stable.
Skizze 3 zeigt am unteren Ende der Trittholme angebrachte und seitlich ausziehbare gebogene Holmpaare, die durch Arretierung ebenfalls ein seitliches Kippen der Leiter verhindern und als andere Form der Seitenstützen anzusehen sind. Die Skizze zeigt die eingefahrene und die ausgefahrene Stellung der Seitenholme in der Perspektivansicht.Sketch 3 shows at the lower end of the step bars attached and laterally Extendable, curved pairs of bars, which can also be tilted to the side by locking prevent the ladder and are to be regarded as a different form of side supports. the Sketch shows the retracted and extended position of the side rails in the Perspective view.
Die schraffierte Fläche zeigt die vergrößerte Aufstandsfläche.The hatched area shows the enlarged contact area.
