Description

  

      Schlossfalle.       Bei den bekannten     Schlossfallen    ist die  Gleitfläche, welche während der Schliessbe  wegung mit dem Schliessblech zusammen  arbeitet, entweder eben oder konvex ge  wölbt. Diese Formen der Gleitfläche haben  den Nachteil, dass das Auftreffen der Falle  auf die Kante .des     Schliessbleches    stossartig  hart und damit relativ geräuschvoll vor sich  geht.  



  Die Erfindung vermeidet diesen Mangel  dadurch, dass die Gleitfläche der Schloss  falle aus einem, bei der Schliessbewegung  zuerst zur Wirkung kommenden, konkav       gel.:#rümmten    Teile und einem erst nachher  zur Wirkung kommenden, konvex gekrümm  ten Teile zusammengesetzt ist, wobei diese  beiden Teile allmählich     ineinander    über  gehen.  



  Die beiliegenden Figuren zeigen ein  Ausführungsbeispiel der Erfindung, und  zwar zeigt       Fig.    1 einen Teilschnitt eines Schlosses.       Fig.        \?    einen     Schrägriss    des     Schloss-          gehäuses    mit der Falle.    Gemäss den Figuren ist die mit dem  Schliessblech     a    wie üblich zusammenarbei  tende Gleitfläche der Falle c in ihrem, bei  der Schliessbewegung zuerst zur Wirkung  kommenden Teil b konkav gekrümmt; dieser  konkav gekrümmte Teil geht allmählich in  den konvex gekrümmten Teile über.

   Beim  Schliessen der Türe oder     dergl.    drängt das  an der Fläche b gleitende Schliessblech ,die  Falle in der Pfeilrichtung zurück, bis diese,  wie üblich, in die     Ausnehmung    d des       Schliessbleches    einschnappt     (Fig.    1 ge  strichelt). Der konkav gekrümmte Teil b  der Falle bewirkt ein stossfreies, sanftes., ge  räuschloses, und vor allem auch leichtes Zu  rückschieben der Falle.  



  In     Fig.    2 ist die Falle in Vereinigung  mit dem     Schlossgehäuse    f zur Darstellung  gebracht.  



  Wie die Figuren zeigen, verläuft die       Riickenfläche    g der Falle gegen die Kante h  zu leicht schräg nach vorne, wodurch das  Einschlüpfen der Falle in die     Verschluss-          stellung    im Schliessblech erleichtert wird.



      Lock latch. In the known lock latches, the sliding surface, which works together with the strike plate during the Schliessbe movement, is either flat or convex ge arched. These shapes of the sliding surface have the disadvantage that the impact of the latch on the edge of the strike plate is suddenly hard and therefore relatively noisy.



  The invention avoids this deficiency in that the sliding surface of the lock is composed of a concave gel.:# curved part that comes into effect during the closing movement and a convex curved part that comes into effect afterwards, these two parts gradually merge into one another.



  The accompanying figures show an embodiment of the invention, namely Fig. 1 shows a partial section of a lock. Fig. \? an oblique view of the lock housing with the latch. According to the figures, the sliding surface of the latch c, which cooperates as usual with the strike plate a, is concavely curved in its part b which first comes into effect during the closing movement; this concavely curved part gradually merges into the convexly curved part.

   When closing the door or the like. The strike plate sliding on surface b pushes the trap back in the direction of the arrow until it snaps into recess d of the strike plate as usual (Fig. 1 dashed lines). The concave curved part b of the trap causes a shock-free, gentle., Ge noiseless, and above all easy to push back the trap.



  In Fig. 2, the case is shown in association with the lock housing f.



  As the figures show, the back surface g of the latch runs too slightly obliquely towards the edge h, which makes it easier for the latch to slip into the locked position in the strike plate.
