Definitions

  • the object of the present invention is an automatic locking system for windows or doors.
  • the invention relates to the technical field of automatic closing systems of doors and windows of buildings and refers to automatic closing systems of a magnetic type.
  • the aim of automatic closing systems is to guarantee that the bolts, also known as "closing points", of a lock installed on a door or window leaf automatically engage, i.e. without the intervention of the user, in special seatings fashioned on the fixed frame of the door or window, when the door or window leaf is in an aligned position to the frame.
  • automatic closing systems comprise a lock body installed on a door or window leaf of the door or window and a counter-plate, commonly known as a "strike-plate", installed on a fixed frame of the door or window.
  • the lock body is provided with bolts, also known as “hooks” or “closing points”, which, when the door or window leaf is in an aligned position to the frame, are released and automatically exit from suitable openings fashioned on the lock body, in order to engage in the counter-plate.
  • a mobile magnet housed in the counter-plate is attracted by the ferromagnetic face-plate of the lock body and exits so as to press a projecting button installed on said face-plate.
  • the button is mechanically connected to an unlocking mechanism for releasing the bolts. Therefore, when the door or window leaf and the frame are aligned, the pressure on the button by the magnet activates the unlocking mechanism, causing the release of the bolts and determining the automatic closing of the door or window.
  • the opening of the door or window occurs by action of a recall mechanism, for example a leverage connected to a handle, which disengages the bolts from the counter-plate.
  • suitable recall means acts on the magnet to cause the magnet to return into the counter-plate; at the same time, said recall means also acts on the unlocking mechanism in order to reposition the unlocking mechanism so that it locks the bolts in a retained condition inside the lock body. In this situation the door or window leaf is distanced from the frame and the door or window is open.
  • the presence of an element (the button) projecting from the face-plate of the lock body compromises the safety of the closing system.
  • this element if this element is accidentally or deliberately pushed, it activates the unlocking mechanism and causes the release of the bolts, also in the non-aligned condition between the door or window leaf and the frame, with the consequence that the bolts do not engage in the counter-plate and therefore do not determine the closing of the door or window.
  • this first prior art disadvantageously functions only with lock bodies having a face-plate made of a ferromagnetic material.
  • closing systems exist in which the unlocking mechanism forms a single part with a first magnet which, when the door or window leaf is aligned to the frame, is attracted by a second magnet housed in the counter-plate and arranged in a facing position to a face-plate of the lock body.
  • the attraction of the first magnet towards the second magnet determines a displacement of the unlocking mechanism, causing the release of the bolts and determining the automatic closing of the door or window.
  • the unlocking mechanism To enable the release of the bolts, it is indispensable for the unlocking mechanism to have a displacement stroke that is sufficient for releasing the release mechanism; therefore, the first magnet is housed in the lock body in a very retracted position with respect to a face-plate thereof, typically at least at about 4 mm from an external surface thereof.
  • WO2017/158449 describes a closing system in accordance with this second prior art in which the second magnet is slidably housed in the counter-plate and, when the door or window leaf is aligned with the fixed frame and the lock body is facing the counter-plate, the second magnet is attracted by a third magnet, rigidly fixed to the lock body, and approaches the first magnet.
  • the closing system is able to operate independently of the distance between the lock body and counter-plate.
  • the activation of the unlocking mechanism and therefore the release of the bolts can also occur in the condition of imperfect alignment between the door or window leaf and the frame, with the consequence that the bolts do not engage in the counter-plate and therefore do not determine the closing of the door or window.
  • Other examples of automatic systems for closing windows and doors are described in EP2634330 , DE8704036 , GB1009996 and US7308737 .
  • an object of the present invention is to make available an automatic closing system for windows or doors, which is reliable and secure, i.e. able to prevent accidental exiting of the bolts, or closing points.
  • “Closing step” is intended as the movement of the window or door leaf from an open position, in which the window or door leaf is not aligned with the fixed frame, towards a closed position, in which the leaf is aligned with the fixed frame.
  • “Approaching step” is intended as that part of the closing step starting from when the lock body starts to face the counter-plate and ending when the window or door is fully closed, i.e. when the window or door leaf and the fixed frame are aligned and the lock body is completely facing the counter-plate.
  • the approaching step is divided into an initial approaching step, starting from when the lock body starts facing the counter-plate until the lock body is partially facing the counter-plate, and a final approaching step, starting from when the lock body is partially facing the counter-plate until the window or door leaf and the fixed frame are aligned and the lock body is completely facing the counter-plate.
  • Opening side of the window or door is intended as the side facing in the direction of opening of the leaf.
  • the opening side corresponds to the side which, in the closing step, last faces the fixed frame or the components of the closing system mounted on the fixed frame.
  • the opening side corresponds to the side which, in the closing step, first faces the window or door leaf or components of the closing system fitted on the leaf.
  • “Closing side” of the window or door is intended as the side facing in the direction of closing of the window or door leaf.
  • the closing side corresponds to the side which, in the closing step, first faces the fixed frame or components of the closing system mounted on the fixed frame.
  • the closing side corresponds to the side which, in the closing step, last faces the window or door leaf or components of the closing system fitted on the leaf.

  • a switch is mounted in the lock body which is configured to assume a locking configuration wherein the switch locks the closing means in the retained configuration and an unlocking configuration wherein the switch unlocks the closing means, thereby activating the automatic movement of the closing means from the retained configuration to the release configuration.
  • the switch and the first member are configured to exchange an activation magnetic-type action adapted to switch the switch from the locking configuration to the unlocking configuration only in a final approaching step of the lock body with respect to the counter-plate, which is a part of a closing step starting from when the lock body is partially facing the counter-plate and ending when the lock body is completely facing the counter-plate.
  • the switch has a first leaf-side magnetic pole active at the front portion of the lock body.

  • the switch has a second leaf-side magnetic pole having opposite polarity to the polarity of the first leaf-side magnetic pole.

  • the switch is movable between a locking position, corresponding to the locking configuration, and an unlocking position, corresponding to the unlocking configuration. Still more preferably the switch is defined by a locking pin axially slidable between the locking position and the unlocking position.

  • the locking pin is rotatable about the longitudinal axis to reverse the position of the first leaf-side magnetic pole and the second leaf-side magnetic pole on the plane of the front portion of the lock body.
  • the first member is movable with respect to the counter-plate.
  • a second member distinct and separate from the switch, is integrally fixed to the lock body in such a way that, when the leaf is aligned with the fixed frame, the second member exercises an attraction force of a magnetic type on the first member which approaches the first member to the lock body in such a way that it magnetically interacts with the switch to activate the automatic switching of the closing means from the retained configuration to the release configuration.
  • the second member is arranged at the front portion of the lock body.
  • the first member is movable, for example slidably or rotatably, between a retracted configuration in which the first member is retracted inside a housing of the counter-plate and an extracted configuration in which the first member is extracted from the housing, to approach the switch.

  • the first magnetic member 3 is preferably movable with respect to the counter-plate 2, and in particular with respect to the housing 2b, between a retracted configuration in which the first member is retracted inside the housing 2b of the counter-plate 2 and an extracted configuration in which the first member is extracted from the housing 2b to approach a switch 5 housed in the lock body 20. Still more preferably the first magnetic member 3 is slidably movable.

  • the switch 5 is distinct and separate from the second magnetic member 6. This circumstance advantageously enables optimising both the functioning of the switch and the positioning of the second magnetic member, since the second magnetic member is most effective in a flush or projecting position with respect to the front portion of the lock body, while the switch is best housed in the lock body for reasons of security.
  • the switch 5 and the second magnetic member 6 can be installed on a same support 7.

  • the first magnetic member 3, when in the extracted configuration, is preferably in a contact configuration, including indirect contact, against an edge surface forming part of the lock body, at the switch.
  • Indirect contact means that the first magnetic member can rest on the aforesaid edge surface also by means of interposition of another member, for example a surface of a containing tray of the first magnetic member.
  • This edge surface can be for example the front portion 20b of the lock body 20 or, as shown in the figures, the support 7.
  • recall means 8 is present for returning the first magnetic member 3 into the retracted configuration inside the housing 2b, when the lock body 20 is distanced from the counter-plate 2, i.e. when the door or window leaf is not aligned to the fixed frame.
