Description

Es ist an sich bekannt, Gleitbahnen an Schleifmaschinen usw. durch harmonikaartige, bewegliche Bälge abzudecken und dadurch eine Verschmutzung zu verhindern. Es ist gleichfalls bekannt, daß man Leder, Papier u. dgl. Natur- oder Kunststoffe durch einfache Faltung ebener Flächen zu Bälgen formen kann, wobei der erhöhten Falte einer Seite eine vertiefte Falte der benachbarten Seite entspricht. Derartige einfach gefaltete, harmonikaartige, unten offene Bälge sind bisher für Gleitbahnschützer nicht zu gebrauchen, weil bei einer Spannung durch betriebsnotwendigen Auszug sich beide Seitenwände erheben, wodurch sich also wieder die vor dem Falten vorhanden gewesene, ebene Fläche ohne Seitenschutz bildet. Beim zurückgehenden Entspannen legt sich aber die Fläche nicht wieder in die gewünschte, harmonikaartige gefaltete Form.It is known per se, slideways on grinding machines, etc. by To cover accordion-like, movable bellows and thereby prevent contamination. It is also known to use leather, paper and the like, natural or synthetic materials can be formed into bellows by simply folding flat surfaces, with the raised Fold one side to match a recessed crease on the adjacent side. Such simply folded, accordion-like bellows open at the bottom have been used for guideway protectors up to now not to be used, because in the event of a voltage due to an operationally necessary pull-out both side walls rise, which means that they were present again before the folding forms a previously flat surface without side protection. When relaxing backwards however, the surface does not return to the desired, accordion-like folds Shape.

Die Erfindung besteht darin, an gefalteten Bälgen die Knickstellen durch Versteifungsmittel, wie Nähte, Klammern oder Niete, festzulegen, wodurch der derart ausgebildete Balg zwangsläufig beim Entspannen in die ursprüngliche Form zurückgeht. Hierdurch wird außerdem der Vorteil erreicht, daß Leder und sonstige weniger biegsame aber haltbare Stoffe zur Herstellung der Bälge benutzbar sind.The invention consists in the kinks on folded bellows by stiffening means, such as seams, staples or rivets, to set what the Bellows designed in this way inevitably return to their original shape when relaxing going back. This also has the advantage that leather and other less flexible but durable materials can be used to manufacture the bellows.

Ferner kann der Balg durch Einlegen von Drähten, Stäben, Schienen usw. aus Metall, Fiber und sonstigen Einlagen in die Nähte oder die Niet- bzw. Klammerstellen derartig in seinem Querschnitt versteift und widerstandsfähiger gestaltet werden, wodurch das lästige Durchhängen der Bälge bei breiteren und längeren Führungsbahnen unterbleibt.Furthermore, the bellows can be made by inserting wires, rods, rails etc. made of metal, fiber and other inserts in the seams or the rivets or staples so stiffened in its cross-section and made more resistant, as a result of the annoying sagging of the bellows with wider and longer guideways is omitted.

In der Zeichnung ist als Beispiel eine Ausführungsform des Erfindungsgegenstands dargestellt. Es zeigt Fig. i eine perspektivische Ansicht eines Gleitschützers, Fig. 2 einen Schnitt nach der Linie C-D der Fig. 3, Fig. 3 einen Schnitt nach der Linie A-B der Fig. 2 und Fig. 4 einen Schnitt nach der Linie E-F der Fig. 3. Fig. i zeigt einen üblich gefalteten Balg mit waagerechten Knickstellen a und den senkrechten Knickstellen b. Fig. 2 zeigt einen Schnitt durch eine senkrechte Knickstelle b. Der Schnitt läßt die durch Niete c befestigten Einlagen d in den Faltungen des Balges erkennen. Aus Fig. 3 ist ersichtlich, wie eine außenliegende Vertikalknickstelle b eine Naht e aufweist, während die innenliegende Vertikalnaht keine Versteifungsausbildung besitzt und die Horizontalknickstellen a durch Niete r zusammengehalten sind. Fig. 2 zeigt Einlagen d in Knickstellen, die durch Niete c zusammengehalten sind, wobei die Niete gleichzeitig die Einlagen d in den Khickstellen c halten und den Balg gegen Durchhängen widerstandsfähiger machen.In the drawing, an embodiment of the subject matter of the invention is shown as an example. 1 shows a perspective view of a sliding guard, FIG. 2 shows a section along line CD in FIG. 3, FIG. 3 shows a section along line AB in FIG. 2, and FIG. 4 shows a section along line EF in FIG 3. Fig. I shows a conventionally folded bellows with horizontal kinks a and vertical kinks b. Fig. 2 shows a section through a vertical kink b. The cut reveals the inserts d fastened by rivets c in the folds of the bellows. From Fig. 3 it can be seen how an external vertical kink b has a seam e , while the internal vertical seam has no reinforcement and the horizontal kinks a are held together by rivets r. 2 shows inserts d in kinks which are held together by rivets c, the rivets simultaneously holding the inserts d in the kinks c and making the bellows more resistant to sagging.
