Dahlhaueer Str. 2 Description of the innovation Folders for sample cards should be made from spring steel with these flexible springs (Fig. 1 + 2) nib plastic cover and a plastic screw or metal plate on lower end, which are formed into an eyelet at the upper end and slide through ice a specially shaped plastic rod, davit the heavy sample card contents can be scrolled without difficulty. The sample files known up to now were “with rigid meaning or plastic screws provided that allow you to turn the page of the content), however locked the contents as the screws were rigid. The content is gone made of rigid cardboard or cardboard inlays, which are patterned with textile or flooring etc. are pasted. These rigid cardboards don't leave me too much, bmeh Turn the page with the pages falling over to the left or right, ma then to lie flat. The spring or plastic screw developed here may change your flexibility (Zehg.l) up to 90 degrees below and bent over »without them Loses elasticity. Both types of screw bend when turning the page with the contents and thus make it possible to “almost flat” Lying of the deposits. (Zehg.l) The spring screw is made of spring steel, the optionally is immersed in plastic or covered with a plastic tube. Aa lower end can be the spring cover made of a steel or resilient metal plate exist or with a plastic screw, matching the internal thread be closed by the spring. Lock the plate or do * plastic screw the lower false inside the portfolio. The upper part of the spring hood is on the other hand, formed into an eyelet from the same spring steel with the same diameter. (Zchg. 2) The eyelet of the feather hood protrudes over the upper rock of the folder out. (Fig. 4) The folder can be equipped with S, 3, 4, or more spring screws will. The eyelets protruding above the upper faIs make them special molded plastic rod (Zohg. 3 + 4) locked and swar in the form that the rod is lifted with the upper end through a & atliehe eyelets. The plastic rod has an even thickness up to the thickened "* lower end (tog. 3), while the The upper end is made so that it can be pressed into the rod. By When the upper end is pressed into the rod, the rod strength results again. (Fig. 3 + 4) This makes it easy to pull the rod into or out of the Eyelets guaranteed. Schntaanspruohe " lX spring cover, characterized in that it is fastened to spring steel and is therefore particularly flexible and is cut off or sanded off at the ends. (Fig. 1 + 2) / 2 ^ Federsehraubs made of spring steel, characterized in that they are made of plastic dipped or injected with plastic eggs but with a plastic handle is covered.

(Fig. 2) / 6) plastic, metal or wooden stick, characterized in that one end is thickened. (Fig. 3) 7) plastic-metal or wooden stick, characterized, (Let the β upper end is designed so that it again reaches rod strength when the pressure part is pressed in (Fig. 3) but stands heöh when not pressed in to prevent the rod from slipping out through the eyelets to prevent. ' 8) spring book screw made of spring steel, according to claim 1 to 4, characterized in that in connection with the plastic rod, according to claim 6 and 7, this plastic rod by impressing the resilient upper part «! can be pushed through the eyelets of the spring socket screw. In the emergency, the plastic rod locks the spring book screws resp. the eyelets, because or cannot slip through. / 9) Federschrauba or plastic screw, according to claims 1-8, characterized in that that the spring body and the screw upper and lower parts can be of any length.
