Description
Fussstütze und Verfahren zu ihrer Herstellung. Die Fussstütze nach der Erfindung ist dadurch gekennzeichnet, dass sie aus Kunst massen und Faserstoffen gebildet ist, derart, dass die Stütze nach Aufhören des auf sie ausgeübten Fussdruckes infolge ihrer Elasti zität wieder ihre ursprüngliche Form anzu nehmen vermag.
Als Faserstoffe können dienen solche na türlicher oder künstlicher Herkunft, wie zum Beispiel Papier, Pappe, Papiermache, Ge webe aus Baumwolle, Leinen usw., Kunst seide, Naturseide, Asbest usw.
Als Kunstmassen können verwendet wer den Kunstharze, wie zum Beispiel Phenol Formaldhyd-Kondensationsprodukte, Kunst horn wie zum Beispiel Galalith, Zellulose verbindungen, wie zum Beispiel Zellulose ester oder -Äther, regenerierte Zellulose, gegebenenfalls in 11Zischung mit 'Weich ma.chern, Vulkanfiber, Hartgummi und viele andere Kunstmassen, die in Verbindung mit Faserstoffen feste aber hochelastische Ge bilde liefern.
Insbesondere sind geruchlose; mindestens nahezu unhygroskopische Kunst massen vorteilhaft verwendbar.
Die Herstellung der Fussstütze aus Kunstmasse und Faserstoff kann in verschie dener Weise erfolgen. So kann der Faserstoff mit der Kunstmasse mehr oder weniger gleichmässig imprägniert werden, es können aber auch Lagen von Faserstoff und Kunst masse miteinander abwechseln oder die Stütze kann aus nur einer oder zwei Lagen Kunstmasse und einer Lage Faserstoff be stehen.
@Sehr zweckmässig ist die Verwendung von härtbaren Kunstharzen zur Herstellung der Stütze, zum Beispiel in der Form von durch das Kunstharz miteinander vereinigten Lagen von Papier, die vor der Härtung durch härtbare Kunstharze miteinander ver klebt bezw. teilweise imprägniert und unter Formgebung unter Anwendung von Druck und Hitze in die Formeiner Stütze gebracht wurden.
Die Herstellung einer Fussstütze erfolgt zweckmässigerweise derart, dass zunächst Teile des Faserstoffes mit der Kunstmasse zusammengebracht werden, worauf man die so behandelten Teile-unter Anwendung von Druck miteinander vereinigt und in die Form der Fussstütze bringt.
Vorteilhafterweise behandelt man Faser stoffe mit solchen löslichen Kunstmassen, die bei Anwendung von Hitze zunächst schmel zen und dadurch miteinander verkleben, dann aber unlöslich und unschmelzbar werden.
Es hat sich als zweckmässig erwiesen, Papier, Pappe, Gewebe oder andere Formen von Faserstoffen mit der Kunstmasse zu tränken bezw. zu überziehen und hierauf zu vereinigen. So kann man zum Beispiel Pa pier mit einer Lösung eines geruchlosen oder geruchschwachen härtbaien Kunstharzes überziehen und nach dem Verdunsten des Lösungsmittels mehrere in passende Form geschnittene Papierstücke unter Anwendung von Druck und Hitze in die Form einer Fuss stütze bringen.
Fussstützen nach der Erfindung sind aus gezeichnet, durch hohe Elastizität, Hitze- und Schweissbeständigkeit, geringes Gewicht und grosse Widerstandsfähigkeit gegen Bruch.
Footrest and method of making it. The footrest according to the invention is characterized in that it is made of synthetic materials and fibers, in such a way that the support is able to resume its original shape after the foot pressure exerted on it has ceased due to its elasticity.
Fibers can be of natural or artificial origin, such as paper, cardboard, paper mache, fabrics made of cotton, linen, etc., artificial silk, natural silk, asbestos, etc.
Synthetic resins, such as phenol formaldehyde condensation products, synthetic horns such as galalith, cellulose compounds such as cellulose esters or ethers, regenerated cellulose, if necessary mixed with soft materials, vulcanized fiber, can be used as synthetic materials. Hard rubber and many other synthetic materials that, in conjunction with fiber, provide solid but highly elastic structures.
In particular, are odorless; at least almost unshygroscopic art masses can be used advantageously.
The production of the footrest from synthetic material and fiber can be done in different ways. So the fiber can be impregnated more or less evenly with the synthetic material, but layers of fiber and synthetic material can alternate with each other or the support can consist of only one or two layers of synthetic material and one layer of fiber.
@Very useful is the use of curable synthetic resins for the production of the support, for example in the form of layers of paper united by the synthetic resin, which glued together ver before curing by curable synthetic resins. partially impregnated and molded into the shape of a support while applying pressure and heat.
A footrest is expediently manufactured in such a way that first parts of the fiber material are brought together with the synthetic material, whereupon the parts treated in this way are combined with one another using pressure and brought into the shape of the footrest.
It is advantageous to treat fibrous materials with such soluble synthetic materials that initially melt when heat is applied and thereby stick together, but then become insoluble and infusible.
It has proven to be useful to soak paper, cardboard, fabric or other forms of fiber with the synthetic material or. to cover and then to unite. For example, paper can be coated with a solution of an odorless or weakly odor hardening synthetic resin and, after the solvent has evaporated, several pieces of paper cut into the right shape can be shaped into a footrest using pressure and heat.
Footrests according to the invention are distinguished by high elasticity, heat and perspiration resistance, low weight and great resistance to breakage.
