Description

  

      Spreizfeder    zum     Festhalten    der Blätter eines geöffneten Buches.    Die Zeichnung veranschaulicht eine bei  spielsweise Ausführungsform des Erfindungs  gegenstandes, und zwar zeigt:       Abb.    1 die Feder in Ansicht,       Abb.    2 die Feder in Anwendung bei ge  öffnetem Buche und       Abb.    3 die Lage der Feder bei geschlos  senem Buche.  



  Die dargestellte Feder besitzt einen fe  dernden Draht mit einem     U-artig    gebogenen  Mittelteil, der beim     Gebrauch    der Feder in  die     Buchrückenöffnung    eingeschoben wird.  Zufolge seiner Federung kann der Draht sich  der Breite des Buchrückens anpassen.  



  Die Schenkel des Drahtes werden an  ihren freien Enden durch eine Zwinge 5  zusammengehalten. An dieser Zwinge ist ein  Griff 4 befestigt, der zur Handhabung der  Feder dient. Dieser     Griff    kann zugleich als       Firmaschild    benutzt werden.  



  Der Draht geht auf der Höhe der Zwinge  in zwei nach entgegengesetzter Seite gerich  tete Arme mit nach innen gebogenen Enden    1 und 2 über. Diese dienen beim Lesen zum  Festhalten der Blätter.  



  Durch das Schliessen des Buches wird  die Feder gespannt, so dass sich das Buch  beim Wiedergebrauch automatisch an der  früher benützten Stelle öffnet.  



  Die Bedienung der Feder geschieht auf  folgende Weise: Man öffnet das Buch, schiebt  den Mittelteil 3 der Feder in die Öffnung  des Buchrückens, hebt dabei die beiden Arme  der Feder, damit ihre umgebogenen Enden  beim Loslassen auf die Blätter des     offenen     Buches zu liegen kommen. Beim Wenden des  Blattes hebt man die Arme der Feder und  zieht diese etwas aus dem Buchrücken her  aus, wendet das Blatt,     sehiebt    die Feder  wieder hinein und lässt deren Arme los.



      Spreading spring for holding the sheets of an open book. The drawing illustrates an example embodiment of the subject invention, namely: Fig. 1 the spring in view, Fig. 2 the spring in use with ge open beech and Fig. 3 the position of the spring in closed beech senem.



  The spring shown has a fe-reducing wire with a U-shaped curved central part, which is inserted into the spine opening when the spring is used. As a result of its springiness, the wire can adapt to the width of the book spine.



  The legs of the wire are held together at their free ends by a clamp 5. A handle 4, which is used to manipulate the spring, is attached to this ferrule. This handle can also be used as a company sign.



  The wire goes at the level of the ferrule in two opposite side gerich ended arms with inwardly bent ends 1 and 2 over. These are used to hold the pages when reading.



  When the book is closed, the spring is tensioned so that when the book is used again it opens automatically at the previously used location.



  The pen is operated in the following way: You open the book, slide the middle part 3 of the pen into the opening of the spine, lifting the two arms of the pen so that its bent ends come to rest on the leaves of the open book when you let go. When turning the sheet of paper, you lift the arms of the pen and pull it out of the spine of the book, turn the sheet, look in the pen again and let go of its arms.
