„Verdrehsichere teleskopierbare Profilkombination""Twist-proof telescopic profile combination"

Die Erfindung betrifft eine Kombination offener oder geschlossener rohrförmiger Profile, die geeignet sind, Objekte wie z.B. Tischplatten, Schübe, Ablagen oder Geräte in einer festgelegten Richtung leichtgängig und geräuscharm zu bewegen.The invention relates to a combination of open or closed tubular profiles which are suitable for moving objects such as table tops, drawers, shelves or devices in a defined direction smoothly and quietly.

Der Stand der Technik beschreibt dafür offene oder geschlossene Profilkombinationen aus Metall oder Kunststoff, indem ein Profil geringerer Abmessung in einer Profilhülle, die das Profil ganz oder teilweise umgibt, längsbeweglich ist.The state of the art describes open or closed profile combinations made of metal or plastic, in which a profile of smaller dimensions is longitudinally movable in a profile shell that completely or partially surrounds the profile.

Zwischen den Profilen befinden sich entweder flüssige oder pastöse Gleitmittel, feste Gleitstoffschichten oder rollbewegliche Elemente, letztere in geeigneten Konturbereichen wenigstens eines Profils dieser Kombination.Between the profiles there are either liquid or pasty lubricants, solid lubricant layers or rolling elements, the latter in suitable contour areas of at least one profile of this combination.

Mängel:Defects:

Beim Einsatz gleitfähiger Profilkombinationen, auch mit Unterstützung durch Hilfsstoffe zum Herabsetzen des Reibkoeffizienten, ist die Qualität der Bewegung und der Aufwand an Verschiebekraft von der Oberflächenrauhheit und der Profilkontur, den Reibkoeffizienten für Ruhe und Bewegung und der senkrecht auf die Reibfläche wirkende Kraft gekennzeichnet.When using sliding profile combinations, also with the support of auxiliary materials to reduce the friction coefficient, the quality of the movement and the amount of displacement force required are characterized by the surface roughness and the profile contour, the friction coefficients for rest and movement and the force acting perpendicularly on the friction surface.

Zwischen die Profile eingefügte rollbewegliche Elemente reduzieren zwar allgemein die für die Relativbewegung erforderliche Kraft. Sie erzeugen aber durch ihre Menge und die bisher verwendete Form der Wälzbahnen, mit der Bewegungsgeschwindigkeit ansteigend, Laufgeräusche und Verschleiß durch Reibung an den Kontaktflächen der Funktionspartner.Although rolling elements inserted between the profiles generally reduce the force required for relative movement, they generate running noise and wear due to friction on the contact surfaces of the functional partners due to their quantity and the shape of the rolling tracks used to date, which increases with the speed of movement.

Beschreibung der erfindungsgemäßen Lösung:Description of the inventive solution:

Die erfindungsgemäße Lösung ist dadurch gekennzeichnet, daß zwei sich ganz oder mindestens mit einem Umschlingungswinkel von mehr als 270 Grad teilweise umhüllenden und als Strang gefertigte Profilrohre 1, 2 in Längsrichtung optimal drei Paar halbe Wälzbahnen 4, 5, 6, deren Profilierung in Ihrer Geometrie vom Kugelradius oder vom Zylinder soweit abweicht, daß nur noch punktförmige oder partiell linienförmige Berührung zwischen den Wälzbahnen in den Profilen und den Wälzkörpern stattfindet, paarweise am Innen- und Außenprofil gegenüberstehend, optimal im Winkel von 120 Grad zueinander um die Mittelachse zentriert, tragen, wobei in jeder Wälzbahn mindestens 2 Wälzkörper 7 durch Hilfsmittel 8 so auf konstanten Abstand gehalten werden, daß sie sich jeweils auf gleicher radialer Höhe gegenüber den Profilen aufhalten und ihr Abstand maximal weniger als die halbe Länge des kürzesten Profilrohrs beträgt. Bei geeigneter maßlicher Kombination der an der Wälzbewegung beteiligten Profile und Wälzkörper bewirkt bereits geringer Kraftaufwand eine präzise und geräuscharme lineare Relativbewegung, die durch eine elektrochemisch erzeugte Beschichtung der Wälzbahnen noch unterstützt werden kannThe solution according to the invention is characterized in that two profile tubes 1, 2 which completely or at least partially envelop each other with a wrap angle of more than 270 degrees and are manufactured as a strand optimally carry three pairs of half rolling tracks 4, 5, 6 in the longitudinal direction, the profiling of which deviates in its geometry from the sphere radius or the cylinder to such an extent that only point-like or partially linear contact takes place between the rolling tracks in the profiles and the rolling elements, in pairs on the inner and outer profile opposite each other, optimally centered at an angle of 120 degrees to each other around the central axis, with at least 2 rolling elements 7 in each rolling track being kept at a constant distance by means of aids 8 so that they are each at the same radial height relative to the profiles and their distance is at most less than half the length of the shortest profile tube. With a suitable dimensional combination of the profiles and rolling elements involved in the rolling movement, even a small amount of force causes a precise and quiet linear relative movement, which can be further supported by an electrochemically produced coating of the rolling tracks
