Abstract
Description
Die Erfindung betrifft eine Strebenverlängerung für einen Schirm, gemäss dem Oberbegriff von Anspruch 1.The invention relates to a strut extension for a screen, according to the preamble of
Bei Schirmen, insbesondere bei Grossschirmen können verschiedene Stoffarten für den Schirmbezug des Schirmdaches mit unterschiedlichen Festigkeiten und anderen Stoffeigenschaften für den Schirm zu Verwendung kommen. Wenn nun eine gemeinsame Schirmkonstruktion für verschiedene Stoffarten etc. zum Einsatz kommen soll, besteht das Problem, dass die Bezugsstoffe sich beim Aufspannen und Schliessen des Schirmes in unterschiedlicher Weise ausdehnen bzw. verziehen können mit der Konsequenz, dass einerseits ein Überdehnen und andererseits ein ungenügendes Spannen des Schirmbezugs möglich ist.For umbrellas, especially for large umbrellas, different types of fabric can be used for the umbrella cover of the umbrella with different strengths and other material properties for the shade. If now a common screen construction for different types of fabrics, etc. is to be used, there is the problem that the cover fabrics can expand or distort during mounting and closing of the screen in different ways with the consequence that on the one hand overstretching and on the other hand insufficient clamping the shield cover is possible.
Bekannt ist einerseits, dass man zur Vermeidung eines Überdehnens oder eines ungenügenden Spannens des Stoffes gefederte Streben oder verstellbare Strebenverlängerungen einsetzt. Dann verbleibt aber immer noch die Möglichkeit, dass zuwenig Federweg nach aussen oder innen zur Verfügung steht, weil bei einem neu konfektionierten Stoffdach die Ausgangsposition des Federwegs anfangs zu nahe an einer der Federweggrenzen liegt.It is known, on the one hand, that spring-loaded struts or adjustable strut extensions are used to avoid overstretching or insufficient tensioning of the material. But then there still remains the possibility that too little spring travel is available to the outside or inside, because with a newly made fabric roof the initial position of the spring travel is initially too close to one of the spring travel limits.
Die Aufgabe der Erfindung ist es, eine Strebenverlängerung für einen Schirm vorzuschlagen, der verbessert für sehr unterschiedliche Ausführungen des Schirmbezugs geeignet ist.The object of the invention is to propose a strut extension for a screen, which is suitable for very different versions of the shield cover improved.
Die Aufgabe der Erfindung wird durch eine variable Strebenverlängerung nach Anspruch 1 gelöst. Dabei haben die Massnahmen der Erfindung zur Folge, dass bei der erfindungsgemässen Strebenverlängerung einerseits eine auf die Stoffart angepasste Federung eingesetzt werden kann und andererseits optimale Federwege eingestellt werden können.The object of the invention is achieved by a variable strut extension according to
Dadurch, dass die Verbindung des Verbindungssteges mit dem Strebenprofil mittels eines verstellbaren Pufferteils vorgesehen ist, ist es möglich, dass wahlweise mehrere Auszugspositionen des Verbindungssteges gegenüber dem Pufferteil so einstellbar sind, dass jeweils eine im wesentlichen optimale Spannung für den jeweiligen Schirmstoff, in Abhängigkeit von der Federkraft vorgewählt werden kann. Dabei ist das Pufferteil zusammen mit dem Verbindungssteg mittels des oder der Federelemente in Längsrichtung des Strebenprofils federnd mit dem Strebenprofil angeordnet. Diese Anordnung wird vorzugsweise dadurch bewirkt, dass der Verbindungssteg teilweise in das Strebenprofil einschiebbar ist.The fact that the connection of the connecting web is provided with the strut profile by means of an adjustable buffer member, it is possible that optionally a plurality of extract positions of the connecting web relative to the buffer member are adjustable so that in each case a substantially optimal voltage for the respective Schirmstoff, depending on the Spring force can be selected. In this case, the buffer member is arranged together with the connecting web by means of or the spring elements in the longitudinal direction of the strut profile resiliently with the strut profile. This arrangement is preferably effected in that the connecting web is partially inserted into the strut profile.
Vorteilhafte Ausgestaltungen sind in den Ansprüchen 2 bis 8 angegeben.Advantageous embodiments are specified in claims 2 to 8.
Vorteilhaft ist eine Ausgestaltung, bei der das Pufferteil eine Führungsgabel aufweist, die den Einstellbereich des Verbindungssteges zumindest zweiseitig umfasst. Dies ergibt gute Führungseigenschaften, insbesondere bei Druckfederelementen. Vorteilhafterweise wird die Einstellbarkeit dadurch erreicht, dass der Verbindungssteg ein linear angeordnetes Lochraster und das Pufferteil eine mit jedem der Löcher des Lochrasters wahlweise positionierbare und mittels eines Querbolzens arretierbare Bohrung aufweist.An embodiment in which the buffer part has a guide fork, which comprises the adjustment region of the connecting web at least on two sides, is advantageous. This results in good leadership properties, especially in compression spring elements. Advantageously, the adjustability is achieved in that the connecting web has a linearly arranged hole pattern and the buffer part has an optionally positionable with each of the holes of the hole pattern and lockable by means of a transverse pin hole.
Eine besonders vorteilhafte Ausgestaltung der Erfindung wird dadurch erreicht, dass ein Gehäuse, mittels dessen der Verbindungssteg, das oder die Federelemente und das Pufferteil als eine Baugruppe ausgebildet ist und das Gehäuse teilweise in das Strebenprofil einschiebbar ist.A particularly advantageous embodiment of the invention is achieved in that a housing, by means of which the connecting web, or the spring elements and the buffer member is formed as an assembly and the housing is partially inserted into the strut profile.
Um zwei Federn optimal einsetzen zu können, können vorteilhafterweise am Pufferteil Trennleisten angeordnet sein, die im Gehäuse getrennte Kammern für die Federelemente bilden.In order to use two springs optimally, can advantageously be arranged on the buffer part separator strips, which form separate chambers for the spring elements in the housing.
Eine gute Führung wird noch dadurch verbessert, dass am Pufferteil, vorzugsweise auf beiden Seiten jeweils eine seitliche Nocke und am Gehäuse jeweils eine bahnförmige Ausnehmung ausgebildet ist, in welcher die entsprechende Nocke jeweils geführt werden kann. Dadurch wird ein Auseinanderfallen der Baugruppenteile verhindert.Good guidance is even further improved in that a lateral cam is formed on the buffer part, preferably on both sides, and a web-shaped recess is formed on the housing, in which the corresponding cam can be guided in each case. This prevents the components from falling apart.
Vorteilhafterweise ist am Gehäuse ein Anschlag ausgebildet ist, mittels welchem ein Einschieben der genannten Baugruppe mit dem Gehäuse, dem Verbindungssteg, der Federelemente und des Pufferteils in das Strebenprofil begrenzt ist.Advantageously, a stop is formed on the housing, by means of which an insertion of said assembly with the housing, the connecting web, the spring elements and the buffer member is limited in the strut profile.
Um ein Vorspannen zu ermöglichen, kann am Verbindungssteg ein Vorspannloch und am Gehäuse eine Vorspannbohrung ausgebildet sein. Dann kann mittels eines Hilfsstiftes der Verbindungssteg mit dem Gehäuse durch die Federelemente vorgespannt arretiert werden. Nach dem Einschieben der Baugruppe in das Strebenprofil bis zum Anschlag kann die Arretierung gelöst werden und die Federn drücken Pufferteil und Verbindungssteg nach aussen.In order to enable a biasing, a biasing hole and the housing, a biasing hole may be formed on the connecting web. Then, by means of an auxiliary pin, the connecting web to the housing can be locked biased by the spring elements. After inserting the module into the strut profile as far as the stop, the catch can be released and the springs push the buffer part and connecting bar outwards.
Die vorbenannten sowie die beanspruchten und in den nachfolgenden Ausführungsbeispielen beschriebenen, erfindungsgemäss zu verwendenden Elemente unterliegen in ihrer Grösse, Formgestaltung, Materialverwendung und ihrer technischen Konzeption keinen besonderen Ausnahmebedingungen, so dass die in dem jeweiligen Anwendungsgebiet bekannten Auswahlkriterien uneingeschränkt Anwendung finden können.The above-mentioned as well as the claimed and described in the following embodiments, according to the invention to be used elements are subject to their size, shape design, material usage and their technical conception no special conditions of exception, so that the well-known in the respective field of application selection criteria can apply without restriction.
