Definitions

  • the present invention relates to a lock for a door or a window.
  • the present invention makes reference to the technical field of door closing devices.
  • such locks have a lock body that can be housed in the thickness of the leaf and comprises the bolt.
  • the bolt is moved between the extracted position and the retracted position thanks to the rotation of a square bar that passes through the lock body.
  • Such locks further comprise a pair of handles at least partially recessed into the exposed surface of the leaf and at least one of which is connected to the square bar so as to control the movement of the bolt.
  • each handle comprises a receptacle adapted to be recessed into the surface of the leaf and configured to receive an actuating member, typically a latch, directly connected to the square bar.
  • an actuating member typically a latch
  • the latch In the handle positioned on the other side, by contrast, typically on the outside of the room, the latch cannot be gripped, but rather has an indentation for a tool, or a coin, so as to allow only a possible emergency opening of the lock and, therefore, of the door or window.
  • the handle on the outside is idly mounted on the square bar.
  • each receptacle requires a recessed seat having a minimum depth, so it is essential that the leaf have a sufficient thickness, both for installing the lock and for creating the recessed seat.
  • handles are not very ergonomic and, especially in the case of hinged leaves, they require auxiliary gripping members, typically extractable. This circumstance introduces constructive complications and higher costs.
  • Document DE 29707200 U1 in accordance with the introductory part thereof, describes a lock for doors of bathrooms or toilets with a rotatable handle disposed inside the room and a display device positioned outside the room to display the "closed" status.
  • one object of the present invention is to provide a lock that can be mounted on leaves having reduced thicknesses.
  • a further object of the present invention is to propose a lock that can be rapidly and easily installed.
  • Another object of the present invention is to provide a lock that is simple to use.
  • a lock for a door or a window according to the invention has been denoted in its entirety by the reference number 1.
  • the lock 1 comprises a lock body 2 connectable to a leaf "A" ( figures 4 and 8 ) of a door or a window.
  • the lock body 2 comprises a locking element 3 that is reversibly movable between a retracted position, in which it is at least partly housed inside the lock body 2, and an extracted position, in which it is at least partly projecting from the lock body 2 so as to define a condition of closure of the door or the window.
  • the locking element 3 comprises a bolt 4.
  • the lock body 2 can comprise a magnetic retaining device 5 configured to interact magnetically with a counter-plate (not illustrated) installed on the frame of the door or the window. In this manner, the leaf “A” can be kept firmly in a closed position without the activation of the bolt 4.
  • the lock 1 further comprises an actuating means 6 for moving the locking element 3.
  • the actuating means 6 comprises a bar 13 with a polygonal cross section which is active on the lock body 2 and reversibly rotatable in order to move the locking element 3 at least between the retracted position and the extracted position.
  • the bar 13 can have a quadrangular cross section, preferably a square one. It should be underscored that the kinematic mechanism of the transmission of motion between the bar 13 and the bolt 4 is of a known type and not illustrated.
  • the lock 1 comprises a fixed handle 7 that is connectable to the leaf "A” and can be gripped by a user.
  • the fixed handle 7 is solidly joined to the lock body 2.
  • the lock 1 comprises a rotating handle 8 that is connectable to the leaf "A” and can be gripped by a user.
  • the rotating handle 8 is solidly coupled to the actuating means 6 and rotatable relative to the lock body 2 in order to move the locking element 3 between the extracted position and the retracted position.
  • the actuating means 6 and at least the rotating handle 8 can be telescopically coupled to enable the lock to be adapted to the thickness of the leaf.
  • the fixed handle 7 and the rotating handle 8 can be disposed, respectively, on the surface of the leaf outside a room and on the surface of the leaf inside a room.
  • the actuating means 6 is disposed at least partly inside the rotating handle 8.
  • the rotating handle 8 can be configured to house the actuating means 6 at least partly, thereby imparting a particular aesthetic appeal to the lock 1.
  • the lock 1 further comprises a first support element 9 and a second support element 10, each having a longitudinal dimension of extension such that they take on a configuration, during use, projecting from a leaf "A".
  • the fixed handle 7 and the rotating handle 8 can be fitted over the first support element 9 and the second support element 10, respectively.
  • this solution is highly ergonomic, as it simplifies the procedure of locking the leaf, allowing the leaf to be closed and subsequently locked with a single continuous sequence of movements of the same hand.
  • this solution makes it possible to simplify and speed up the installation of the lock by minimising the milling operations on the leaf "A" compared to the prior art.
  • the present lock 1 can be advantageously mounted on leaves having a reduced thickness, even only slightly larger than that of the lock body 2. Therefore, the lock according to the invention can have particular and effective application on glass leaves and, in general, on leaves having a thickness equal to or less than 14 millimetres.
  • the first support element 9 and the second support element 10 can be completely housed inside the fixed handle 7 and the rotating handle 8, thus being, during use, substantially out of view so as to increase the aesthetic appeal of the lock 1.
  • the fixed handle 7 and/or the rotating handle 8 can be in the form of a knob, thus ensuring optimal ergonomics and a high aesthetic appeal of the lock 1.
  • the handle can have a different form, for example to satisfy the user's needs, without altering the inventive concept of the present invention.
  • the lock 1 comprises a circlip 30 active on the rotating handle 8 in order to keep it fitted over the second support element 10.
  • the lock 1 comprises a connecting grub screw 40 active on the fixed handle 7 in order to keep it fitted over the first support element 9.
  • the first support element 9 and the second support element 10 are connectable to the leaf "A" and/or lock body 2 so that the latter is at least partly interposed between them, and thus between the fixed handle 7 and the rotating handle 8.
  • the lock 1 can comprise fixing elements 11, for example screws, suitable for connecting the first support element 9 and the second support element 10 to the leaf "A", thereby ensuring particular stability and robustness of the lock 1.
  • the fixing elements 11 are connected to the first support element 9 and second support element 10 in such a way that, during use, the fixed handle 7 and the rotating handle 8 are opposite relative to the leaf "A" of the door or window and, preferably, have respective axes of extension that coincide.
  • the axes of extension of the handles 7, 8 coincide with the axis of extension of the bar 13.
  • the first support element 9 and the second support element 10 can have, respectively, a pair of housings 50 adapted to receive, by insertion, the fixing elements 11.
  • the fixing elements 11 can comprise four screws, each of which inserted into a corresponding housing 50 and screwed, when in use, directly onto the leaf "A".
  • the fixing elements 11 can, when in use, pass through the leaf "A" and the lock body 2.
  • the fixing elements 11 can be inserted into the housings 50 of the first support element 9 so as to be connected to respective housings 50 of the second support element 10, in such a way as to maintain the first support element 9 and the second support element 10 constrained to the leaf "A".
  • the fixing elements 11 can be inserted into the housings 50 of the first support element 9 and screwed into a respective female screw inserted in the housings 50 of the second support element 10.
  • the fixed handle 7 and the rotating handle 8 can be fitted, during use, over the support elements 9, 10, they hide the fixing elements 11 from view, thus imparting aesthetic quality to the lock 1.
  • the lock 1 can comprise an auxiliary control device 12 at least partly housed in the fixed handle 7.
  • the auxiliary control device 12 can be activated in order to move the locking element 3 at least from the extracted position to the retracted position.
  • the auxiliary control device 12 can define, for example, an emergency opening system for the door or window.
  • the auxiliary control device 12 can further be activated in order to reversibly move the locking element 3 from the retracted position to the extracted position.
  • the auxiliary control device 12 comprises a control member 14 solidly joined to the bar 13 and having a seat 15, preferably an indentation, adapted to receive a tool for external actuation by a user.
  • the tool for external actuation can consist in a coin and/or the tip of a screwdriver.
  • control member 14 is fitted over the bar 13 and coupled thereto by virtue of their mating shape, in such a way as to optimise the overall dimensions of the lock 1.
  • control member 14 has a first portion 16, fitted over the bar 13, and a second portion 17 exposed to view (when the lock is in use) and bearing the seat 15.
  • the first portion 16 and the second portion 17 are reciprocally constrained by virtue of their mating shape, thus minimising the connection elements and simplifying the manufacturing process.
  • first portion 16 and the second portion 17 can be reciprocally press fitted.
  • first portion 16 is connected to the bar 13 by means of a circlip 30 which ensures an adequate positioning thereof relative to the first support element 9 of the fixed handle 7.
  • the lock 1 comprises a cylinder 18 having a shank 19 over which the rotating handle 8 is fitted.
  • the rotating handle 8 and the shank 19 are reciprocally coupled in rotation by means of a coupling grub screw 40.
  • the shank 19 essentially defines the actuating means 6.
  • the fixed handle 7 has an access opening 20 for accessing the cylinder 18 to allow the insertion of a key "C" by a user.
  • the cylinder 18 can also perform the function of an auxiliary control device for emergency opening.
  • a plug 21 is further present; it is insertable into the access opening 20 and provided with a through slot adapted to allow the insertion of the key "C".
  • the plug 21 can be connected to the fixed handle 7 by means of a circlip 30 which ensures the correct positioning thereof relative to the access opening 20.
  • the present invention relates to a door or window comprising a supporting frame, a leaf "A" which is reversibly movable relative to the frame between at least an open position and a closed position, and a lock in accordance with what was previously described.
  • the present invention achieves the proposed objects by providing a lock for a door or a window that can also be installed on leaves having reduced thicknesses.
  • the lock according to the invention is capable of enhancing the ergonomics and convenience for the user thanks to the presence of a fixed handle and a rotating handle which can be fitted, during use, over a first and a second support element so as to take on a configuration of projecting from the leaf.
  • the present invention provides a lock with a "knob"-style handle with a gripping system and a leaf stop system in a single solution for locks with one or more points of activation of the lock for the leaf.
