Description
Die Erfindung betrifft eine trittsichere StuhlfĂĽhrungsvorrichtung, umfassend:
- ein längliches, flaches Gehäuse, an dem ein Deckel abnehmbar und nicht sichtbar befestigt ist,
- zwei innerhalb des Gehäuses angeordnete, zueinander parallel verlaufende Linearführungen,
- einen eine Stuhlbasis tragenden Schlitten, welcher von der LinearfĂĽhrung getragen und/oder gefĂĽhrt wird,
- an elongate, flat housing to which a lid is detachably and not visibly attached,
- two linear guides arranged parallel to one another within the housing,
- a chair base supporting carriage which is supported and / or guided by the linear guide,
Eine StuhlfĂĽhrungsvorrichtung der eingangs genannten Art ist u. a. durch
Solche Stuhlführungsvorrichtungen kommen überwiegend in Konferenzräumen bzw. Sitzungsälen zum Einsatz. Sie sollen einen gewünschten, regulierbaren Abstand vom Konferenztisch und kollisionsfreie Passierräume schaffen. Der Stuhl wird im Wesentlichen senkrecht zum Konferenztisch bewegt, vor dem die Stuhlführungsvorrichtung angeordnet ist. Normalerweise wird die Stuhlbasis bzw. Stützsäule des Stuhls längs eines am Deckel eingebrachten Langlochs zur Schaffung eines Fahrkanals geführt, welcher im Bereich einer Längsachse des Gehäuses angeordnet ist. Die Breite des Langlochs beträgt wenigstens 20 mm und ist durch die Art der Befestigung und Kraftableitung vorbestimmt. Der am bodenebenen Gehäuse eingebrachte, beispielsweise 22 mm breite Fahrkanal ist jedoch mit den gültigen Bauvorschriften betreffend Anforderungen an Gehbereiche nicht konform. Demnach sollen nach den Richtlinien der Bundesanstalt für Arbeitsschutz und Arbeitsmedizin zur Vermeidung von Stolpern, Umknicken und Fehltreten die Spalten in Gehbereichen den Wert von 10 mm nicht überschreiten. Im Übrigen trägt diese Erfindung den Anforderungen des barrierefreien Bauens Rechnung. Aufgrund der schmalen Fahrkanäle stellen diese Stuhlführungsvorrichtungen im Vergleich zu bisher marktüblichen Systemen kein Hindernis für z.B. Rollstuhlfahrer oder auf Gehstützen angewiesene Personen dar.Such chair guide devices are mainly used in conference rooms or meeting rooms. They should create a desired, adjustable distance from the conference table and collision-free passages. The chair is moved substantially perpendicular to the conference table, in front of which the chair guide device is arranged. Normally, the chair base or support pillar of the chair is guided along a slot provided on the cover to create a driving channel, which is arranged in the region of a longitudinal axis of the housing. The width of the slot is at least 20 mm and is determined by the type of attachment and power dissipation. However, the introduced on the floor level housing, for example, 22 mm wide drive channel is not compliant with the current building codes regarding requirements for walking areas. According to the guidelines of the Federal Institute for Occupational safety and occupational medicine, the columns in walking areas should not exceed the value of 10 mm to avoid tripping, kinking and miscarriage. Incidentally, this invention takes into account the requirements of barrier-free construction. Due to the narrow travel channels, these chair guide devices are no obstacle to, for example, wheelchair users or persons assigned to crutches in comparison to conventional systems.
Es stellt sich daher die Aufgabe, eine neuartige Stuhlführungsvorrichtung der im Oberbegriff genannten Art zu konzipieren, deren Konstruktion den oben erwähnten Anforderungen Rechnung tragen kann.It is therefore the task of designing a novel chair guide device of the type mentioned in the preamble, whose construction can take into account the above-mentioned requirements.
Diese Aufgabe ist durch eine gattungsgemäße Stuhlführungsvorrichtung gelöst, bei der:
- am Deckel wenigstens zwei zueinander parallel verlaufende Fahrkanäle zur Aufnahme von Führungselementen angeordnet sind,
- die FĂĽhrungselemente mit der Stuhlbasis verbunden oder Teil der Stuhlbasis sind.
- at least two mutually parallel running channels for receiving guide elements are arranged on the cover,
- the guide elements are connected to the chair base or are part of the chair base.
Die Führungselemente können als Stege vorliegen, welche vorzugsweise in einem Materialstück mit der Stuhlbasis ausgeführt sind.The guide elements may be present as webs, which are preferably carried out in a piece of material with the chair base.
Eine andere Ausführungsform sieht vor, die in die Fahrkanäle eingreifenden Führungselemente als Führungsbolzen oder -schrauben auszuführen. Solche Führungselemente können beispielsweise Madenschrauben mit Innensechskant, Stehbolzen mit Auflagerteller, Schrauben mit Distanzhülse etc. sein.Another embodiment provides to perform the engaging in the driving channels guide elements as guide bolts or screws. Such guide elements may be, for example, grub screws with hexagon socket, stud with bearing plate, screws with spacer, etc.
Vorzugsweise sind am Deckel zwei zueinander parallel verlaufende Fahrkanäle eingebracht, welche spiegelsymmetrisch zu der Längsachse des Gehäuses angeordnet sind und jeweils eine lichte Breite aufweisen, welche den Wert 10 mm nicht überschreiten. Vorzugsweise liegt die lichte Breite bei maximal 6 mm. Auf diese Weise kann die Anforderung an Trittsicherheit erfüllt werden.Preferably, two mutually parallel driving channels are introduced on the cover, which are arranged mirror-symmetrically to the longitudinal axis of the housing and each having a clear width, which do not exceed the
Dieses Breitenmaß erfordert jedoch die Einführung neuer technischen Maßnahmen, mit welchen die Stabilität der Stuhlbasis und damit des Stuhls in Ruheposition und während der Hin- und Herbewegung sowie bei Hinsetzen und Aufstehen der unter der Last der auf dem Stuhl sitzenden Person gewährleistet werden kann.However, this width dimension requires the introduction of new technical measures with which the stability of the chair base and thus the chair in rest position and during the reciprocating motion and when sitting down and getting up under the burden of sitting on the chair person can be guaranteed.
Zu solchen Maßnahmen gehört vor allem eine stabile Verbindung der Stuhlbasis mit dem Schlitten, zum Beispiel über Schraubverbindungen, wie Madenschrauben. Die Stuhlbasis bildet zusammen mit dem Schlitten ein Modul, welches seine Lage gegenüber dem Deckel nach Anbringen einer Kraft, in der Art einer Laufkatze ändern kann.Such measures include above all a stable connection of the chair base with the carriage, for example via screw, such as grub screws. The chair base together with the carriage form a module which can change its position relative to the lid after application of a force, in the manner of a trolley.
Vom Vorteil ist dabei, dass die Stuhlbasis in Draufsicht auf eine Flachseite des Schlittens einen Umriss aufweist, der sich etwa mit einem Umriss des Schlittens deckt. Dies erleichtert den Einsatz von Schraubverbindungen, wie besagten Madenschrauben, welche beispielsweise zur Fixierung der Stuhlbasis am Schlitten von außen her schräg eingedreht werden können. Sollten die Führungsbolzen oder -schrauben eingesetzt sein, so können diese an einer Peripherie der Stuhlbasis angeordnet sein. Durch diese technischen Maßnahmen kann die Stabilität des Moduls noch erhöht werden. Selbstverständlich ist es möglich, die Länge der Stuhlbasis gegenüber dem Schlitten zu vergrößern.The advantage here is that the chair base in plan view of a flat side of the carriage has an outline that approximately coincides with an outline of the carriage. This facilitates the use of screw, as said grub screws, which can be screwed in, for example, for fixing the chair base on the slide from the outside obliquely. If the guide bolts or screws are used, they may be located at a periphery of the chair base. Through these technical measures, the stability of the module can be increased. Of course, it is possible to increase the length of the chair base relative to the carriage.
Vorzugsweise sind auf einer Unterseite des Schlittens U-förmige Führungsschienen und/oder Führungswagen befestigt, deren Abstand voneinander dem der Linearführungen entspricht und deren Mittelstege - im zusammengesetzten Zustand der Stuhlführungsvorrichtung - jeweils mit einer Linearführung kontaktieren.Preferably, U-shaped guide rails and / or carriages are mounted on a bottom of the carriage whose distance from each other corresponds to the linear guides and the center webs - in the assembled state of the chair guide device - each contact with a linear guide.
Dadurch, dass die am Deckel eingebrachten Fahrkanäle sehr schmal sind, kann auf - marktübliche, unterhalb des Deckels befindliche und vor dem Eindringen von Schmutzpartikeln schützende - Abdeckgurte verzichtet werden.Due to the fact that the driving channels introduced on the cover are very narrow, it is possible to dispense with covering belts which are customary in the market, located below the cover and protect against the penetration of dirt particles.
Weiterhin kann die Stuhlführungsvorrichtung mit wenigstens einer innerhalb des Gehäuses untergebrachten direkten oder indirekten Antriebstechnik ausgestattet sein, durch die eine Rückstellung des Moduls bewirkt wird, um den Stuhl nach Verlassen in eine definierte Position, z.B. direkt an den Konferenztisch, zu verfahren. Vorzugsweise, allerdings nicht zwingend, kommt eine Gasdruckfeder zum Einsatz, welche über ein Dämpferelement, wie Flaschenzug, sowohl mit dem Schlitten als auch mit einem ortsfesten Befestigungspunkt verbunden ist. Alternativ zu einer Rückholfeder kann die Schienenführung auf einer in das Gehäuse integrierten, schiefen Ebene oder einer Kippplatte angebracht sein. Hierbei wird auf

Durch Drehen des Führungselementes 40 um 60° kann die ganze Einheit wahlweise befestigt oder gelöst werden. Das Federelement 40 übt im montierten Zustand eine Vorspannkraft auf das Führungselement 40 aus und verhindert so ein Herausrutschen des Rastbolzens 44 aus der Rastkerbe 45. Zur Montage/Demontage wird zunächst eine in Achsrichtung des Führungselementes 40 wirkende Kraft eingebracht mittels derer der Rastbolzen 44 aus der Rastkerbe 45 herausgedrückt wird. Anschließend kann der Führungsbolzen um 60° gedreht und im Anschluss daran aus der Halteplatte 42 durch das Langloch 46 demontiert werden.
