Definitions

  • the present invention regards a lock for doors/windows/shutters according to the preamble of the independent claim.
  • the present lock is adapted to be advantageously used in the field of production of accessories for doors/windows/shutters, in particular in the field of production of locks, in particular locks with latch bolt and it is intended to be used for opening and closing the door/window/shutter itself, such as a door.
  • the present invention falls within the field of production of doors/windows/shutters, in particular in the field of production of accessories for doors/windows/shutters and still more particularly in the field of production of locks.
  • a lock according to the preamble of the independent claim 1 is disclosed in document US 2016/305161 A1 .
  • Multiple types of locks for closing and opening doors/windows/shutters are known on the market, e.g. for moving the movable wing of a door with respect to a fixed frame placed to border an opening screened by the movable wing itself.
  • the locks for doors/windows/shutters of known type comprise a box-like containment body intended to be embedded in the movable wing of the door/window/shutter, e.g. in the movable wing of a door.
  • the box-like body is provided with a front plate intended to be visible on a free lateral edge of the movable wing of the door; such edge is substantially vertical and is susceptible of facing a fixed upright of the frame.
  • the lock also comprises at least one latch bolt, normally made of metal material or hard plastic material, slidably inserted within the box-like body and placed to cross an opening made on the front plate of the box-like body.
  • the latch bolt is extended between two opposite ends, including a stop portion susceptible of being inserted within a shaped counter-plate (called such in the jargon of the field) and a movement portion placed within the box-like body.
  • the shaped counter-plate is normally made of metal material or hard plastic material, and is housed in the fixed upright of the frame of the door/window/shutter.
  • the shaped counter-plate defines a housing cavity for at least partially containing the stop portion of the latch bolt.
  • the latch bolt is movable between an extended position, in which it is partially extracted from the box-like body, with the stop portion placed within the shaped counter-plate, locking the movable wing of the door/window/shutter in a closed position in which it is placed to cover the opening to be screened, and a retracted position, in which the latch bolt is housed within the box-like body, it is mechanically released from the shaped counter-plate so that the user is free to move the movable wing with respect to the fixed frame, for example by rotating the door on the hinges provided on an upright of the frame in order to free the opening.
  • the locks of known type are provided with at least one handle that can be maneuvered by the user and movement means housed within the box-like body mechanically connected to the handle and to the latch bolt.
  • the handle is placed to cross the box-like body and is mechanically connected to the movement means, which usually comprise a cam which engages the movement portion of the latch bolt.
  • the lock described herein is provided with two different latch bolts, slidable in a parallel manner along two substantially horizontal directions and arranged one on top of the other.
  • Such latch bolts are both susceptible of being moved independently between the lock position and the release position in order to be respectively locked with a first and a second shaped counter-plate, provided vertically aligned and each provided with a shaped seat in order to house the stop portion of the corresponding latch bolt.
  • the latch bolt of the lock of known type (also known, in the technical jargon of the field, as a lock with mechanical latch bolt) is always at least partially extracted from the box-like body, in extended position, also with the movable wing in open position.
  • the user In order to bring the movable wing into the closed position, the user must actuate the handle and bring the latch bolt into the retracted position, bring the wing of the door/window/shutter into the closed position and release the handle. At this point, the latch bolt is spontaneously moved by the movement means from the retracted position to the extended position, in which it engages the cavity of the shaped counter-plate and locks the movable wing in the aforesaid closed position.
  • the main drawback lies in the fact that the stop portion of the latch bolt produces an unpleasant sharp noise when it is placed within the housing cavity of the corresponding shaped counter-plate, with the latch bolt in the extended position in order to lock the movable wing in the closed position.
  • the movable wing of the door/window/shutter such as a door
  • the latch bolt is forced to be moved from the extended position (in which it is normally situated) to the retracted position by interference with the fixed upright of the frame of the door/window/shutter, in order to then return into extended position once the latch bolt is aligned with the cavity of the shaped counter-plate.
  • Such forced movement of the latch bolt generated by the interference with the upright generates a noise that is annoying for the user.
  • a further drawback lies in the fact that the stop portion of the latch bolt remains permanently outside the front plate of the box-like body of the lock, and is therefore visible when the movable wing of the door/window/shutter is in open position.
  • the visible latch bolt is deemed unaesthetic with regard to outward appearance, since today - in the world of fashion and design - "clean" external lines are preferred.
  • a lock for doors/windows/shutters has for some time been known as provided with latch bolt with magnetic actuation.
  • first magnet and the second magnet of the lock of known type are both provided with two magnetic poles, aligned with each other along a substantially horizontal direction.
  • the second magnet is housed in the shaped counter-plate at a bottom wall thereof facing an access opening for the insertion of the stop portion of the latch bolt.
  • the first magnet of the latch bolt is aligned with and attracted by the second magnet of the shaped counter-plate when the movable wing of the door/window/shutter is moved into the closed position, automatically moving it from the release position into the lock position.
  • the latch bolt is configured for being invisible with the movable wing of the door/window/shutter in the open position, e.g. with the stop portion terminating with a substantially smooth wall on the same plane as the front plate.
  • the lock with magnetic latch bolt of known type is adapted to produce less noise when the stop portion of the latch bolt enters into the cavity of the shaped counter-plate, since even if the movable wing is moved close to the fixed upright in order to close the door/window/shutter, the latch bolt does not interfere with the upright itself, and therefore does not generate any annoying noise.
  • the latch bolt exits from the box-like body in order to be brought into closed position only when it is aligned with the magnet of the shaped counter-plate, without substantially intercepting the upright, reducing the generated noise.
  • Such milling operation is particularly costly and above all requires very thick and strong frames so that they can receive one such deep milling.
  • the problem underlying the present invention is therefore that of overcoming the abovementioned drawbacks by providing a lock for doors/windows/shutters which is provided with a shaped counter-plate with limited size.
  • a further object of the present invention is to provide a lock for doors/windows/shutters which is quick and simple to install.
  • a further object of the present invention is to provide a lock for doors/windows/shutters which is entirely reliable in operation.
  • a further object of the present invention is to provide a lock for doors/windows/shutters which is simple to use.
