Definitions

  • the present invention relates to an assembly for preventing misregistration of the driven gear that actuates the closing and opening mechanism upon insertion of the cylinder with the key in a lock, particularly for locks in which the cylinder is to be inserted after fitting said lock to the door panel for which it is intended.
  • a lock is usually fitted to a door panel in two successive steps: the lock body is inserted in the recess provided on the side of the door panel that lies opposite with respect to the side that is pivoted to the supporting structure; then the cylinder is inserted in a transverse opening of the door panel that faces the appropriately provided seat formed in the body of the lock.
  • the lock is usually operated several times to check its good operation and placement on the supporting structure. During this step, when the cylinder is not present, it is important to ensure that the internal gears of the lock do not move, in order to prevent their incorrect movement from causing a loss of register of the system and therefore a meshing condition that is different from the one intended for correct operation.
  • the aim of the present invention is to obviate the cited drawbacks and to meet the mentioned requirements, by providing an assembly for preventing misregistration of the driven gear that actuates the closing and opening mechanism upon insertion of the cylinder with the key in a lock, which forces the mating of the driven gear with the cylinder in the initial configuration assigned to the driven gear by the manufacturer.
  • an object of the present invention is to provide an assembly that is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost.
  • the present assembly for preventing misregistration of the driven gear that actuates the closing and opening mechanism upon insertion of the cylinder with the key in a lock, characterized in that an oscillating lever is mounted in the lock and has a coupling end that is forced by elastic means into a recess of said driven gear in the absence of said cylinder, and in that said cylinder, once inserted, interferes, with a portion of its contour, with a protrusion of said lever and, by overcoming the action of said elastic means, disengages said coupling end.
  • the reference numeral 1 generally designates a lock of the type that is adapted to be inserted in the recess provided on the side of the door panel that lies opposite with respect to the side that is hinged to the supporting structure (fixed or movable wall).
  • the lock 1 is a box-like body 2 that is shaped like a parallelepiped and is provided with a plurality of distributed recesses; its face that lies opposite the one on the back wall of the recess of the door panel is coupled to a faceplate 3 for fixing to said door panel.
  • One of the recesses is arranged in the lower part of the box-like body 2 and is a through recess: it is the seat 4 of the cylinder.
  • a driven gear 5 surrounds the cylinder and accommodates the cam in a radial slot: since the gear 5 is functionally connected to the gears of the lock, its rotations produce, in one direction, the closure of a bolt 7 and, in the other direction, the opening of the bolt 7 and then the opening of a latch 8.
  • the driven gear 5 is locked due to the presence of a coupling end 10 of an oscillating lever 9 in a recess 11 arranged in the peripheral region of the driven gear 5 at the space that lies between the two successive teeth 6a and 6b.
  • the end 10 is forced into the recess 11, since the lever 9 is pivoted by means of a pivot 12 in the lower end of the box-like body 2 and is pushed by a helical spring 13 that acts with its head on the lower surface of a protrusion 14 and with its tail on the lower end of the box-like body 2.
  • the protrusion 14 is provided in such a manner that its upper surface is hump-shaped, with its greatest protrusion at the central section, and its ends, when the lock 1 is fitted without the cylinder inserted therein, are aligned with the lower profile of the seat 4. This shape is necessary to allow the easy insertion of the cylinder in the seat 4 without causing jamming thereof.
  • the box-like body 2 of the lock 1 is inserted in the recess provided on the side of the door panel that lies opposite the side that is hinged to the supporting structure (fixed or movable wall).
  • the movement of the driven gear 5 is prevented by the presence of the coupling end 10 of the oscillating lever 9 in the recess 11 arranged on the peripheral region of the driven gear 5 at the space comprised between the two successive teeth 6a and 6b.
  • the insertion of the cylinder within the seat 4 entails that the lower end of the cylinder acts on the protrusion 14, lowering it and accordingly compressing the helical spring 13.
  • the oscillating lever 9 can have a U-shaped coupling end 10a that is adapted to enter the space between the two successive teeth 6a and 6b without having to provide a specifically formed recess 11 as in the preceding description.
