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 unblocking 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 unblocking mechanism, causing release of the bolts and determining the automatic closure 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.
  • 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 unblocking mechanism and causes 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 lock.
  • this first prior art disadvantageously functions only with the lock bodies having a face-plate made of a ferromagnetic material.
  • the unblocking 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 unblocking mechanism, causing release of the bolts and determining the automatic closure of the door or window.
  • the unblocking mechanism To enable the release of the bolts, it is indispensable for the unblocking mechanism to have a displacement run that is sufficient for liberating 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.
  • the second prior art application described above also has some important drawbacks.
  • the distance between the lock-body and the counter-plate is not fixed, but can vary between various doors or windows.
  • a greater force of magnetic attraction is necessary, and therefore magnets having greater power are required; differently, when the distance is at a minimum, the magnets having greater power risk activating the release of the bolts before time, before the door or window leaf is completely aligned to the fixed frame. Therefore, the systems of the second prior art are disadvantageously very difficult to calibrate and can be considerably unreliable.
  • a further drawback is represented by the fact that, in the presence of face-plates of the lock-body made of a ferromagnetic material, the retracted position of the first magnet compromises the intensity of the reciprocal magnetic force of attraction with the second magnet, owing to the magnetic disturbances induced by the ferromagnetic material of which the face-plate is made. Therefore, these closing systems disadvantageously have a poorly efficient operation with face-plates made of ferromagnetic material.
  • the technical task underpinning the present invention is to provide an automatic closing system for windows or doors that obviates the drawbacks of the prior art mentioned above.
  • an aim 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 tampering and accidental exiting of the bolts, or closing points.
  • a further aim of the present invention is to realise an automatic closing system for windows or doors able to function both with ferromagnetic face-plates or with non-ferromagnetic face-plates.
  • a further aim of the present invention is to make available an automatic closing system for windows or doors which, when the door or window leaf is aligned to the fixed frame, is able to function independently of the distance between the lock-body and the counter-plate.
  • the present invention relates to an automatic closing system for windows or doors, which activates the release of the closing means following an interaction of a magnetic type between a first member, installable on a fixed frame, and a switch, installable on a door or window leaf, and wherein a first member is neared to the switch by effect of an attraction force exerted by a second member.
  • the automatic system comprises a counter-plate installable on a fixed frame and provided with a first member that is mobile with respect to the counter-plate.
  • a lock-body is present, installable on a door or window leaf and provided with closing means mobile between a release configuration, in which the closing means engage the counter-plate, and a retained configuration, in which the closing means are maintained internally of the lock-body and do not engage the counter-plate.
  • the system comprises a switch housed in the lock-body for activating a switching of the closing means at least between the retained configuration and the release configuration.
  • the system further comprises a second member solidly fixed to the lock-body so that, when the lock-body is proximal to the counter-plate, said second member exchanges, with the first member, an attraction force of a magnetic type which nears said first member to the lock-body so that it interacts magnetically with the switch for activating the automatic switching of the closing means between the retained configuration and the release configuration.
  • the switch is defined by a blocking member slidable between a blocked position, corresponding to the retained configuration of the closing means, and an unblocked position, corresponding to the release configuration of the closing means.
  • first member, the second member and the blocking member are made of different combinations of material.
  • the first and the second member can be made of a material magnetic and the blocking member can be made of a ferromagnetic material.
  • first member, the second member and the blocking member are made of a magnetic material
  • the first member is made of a magnetic material
  • the second member and the blocking member are made of a ferromagnetic material.
  • the first member and the blocking member are made of a magnetic material, while the second member is made of a ferromagnetic material.
  • the first member is made of a ferromagnetic material
  • the second member and the blocking member are made of a magnetic material.
  • first and the second member are made of a ferromagnetic material, while the blocking member is made of a magnetic material.
  • an automatic closing system for windows or doors is denoted in its entirety by number 1.
  • the system 1 comprises a counter-plate 2 installable on a fixed frame (not illustrated) and provided with a first member, preferably a first magnetic member 3, mobile with respect to the counter-plate 2.
  • the magnetic member 3 is preferably defined by a magnet of a permanent type.
  • the counter-plate can be made of a ferromagnetic material or a non-ferromagnetic material.
  • the system 1 comprises a lock-body 20 installable on a door or window (not illustrated) and provided with closing means 4.
  • the closing means 4 are mobile between a release configuration ( figure 1 ), in which the closing means 4 engage the counter-plate 20, and a retained configuration ( figure 2 ), in which the closing means 4 are maintained internally of the lock-body 20 and do not engage the counter-plate.
  • the closing means preferably comprise a hook 4a which has a hooked portion 4b suitable for engaging a portion 2a of the counter-plate 2.
  • the system 1 comprises a switch 5 housed in the lock-body 20 for activating a switching of the closing means 4 at least between the retained configuration ( figure 2 ) and the release configuration ( figure 1 ).
  • the switch can be housed completely internally of the lock-body 20. This configuration advantageously prevents accidental activation, or tampering, with the closing system, ensuring the security of the lock.
  • the system comprises a second member, preferably a second magnetic member 6, solidly fixed to the lock-body 20 so that when the lock-body 20 is proximal to the counter-plate 2, said second magnetic member 6 exerts an attraction force on a the first magnetic member 3 so as to near the first magnetic member 3 to the lock-body 20; in this way, the first magnetic member 3 interacts magnetically with the switch 5 for activating the automatic switching of the closing means 4 between the retained configuration ( figure 2 ) and the release configuration ( figure 1 ).
  • a second magnetic member 6 solidly fixed to the lock-body 20 so that when the lock-body 20 is proximal to the counter-plate 2, said second magnetic member 6 exerts an attraction force on a the first magnetic member 3 so as to near the first magnetic member 3 to the lock-body 20; in this way, the first magnetic member 3 interacts magnetically with the switch 5 for activating the automatic switching of the closing means 4 between the retained configuration ( figure 2 ) and the release configuration ( figure 1 ).
  • the fixed second magnetic member 6 attracts the mobile first magnetic member 3 so as to near it to the switch 5 which, almost simultaneously, activates the release of the closing means which block the door or window leaf.
  • the closing means 4 comprise a hook 4
  • the switch 5 activates the release of the hook 4, which, on crossing an opening 20a of the lock-body 20, hooks the hooked portion 4b thereof to the portion 2a of the counter-plate 2.
  • the second magnetic member 6 is preferably defined by a magnet of a permanent type.
  • the second member 6 is arranged at a front portion 20b of the lock-body 20 destined to face the counter-plate 2.
  • the second member 6 can be embedded in the front portion 20b of the lock-body 20 and arranged flush with an edge surface thereof.
  • the second member is embedded in the front portion of the lock-body, projectingly with respect to an edge surface of the front portion.
  • the second magnetic member projects by a distance preferably comprised between about 0 mm and about 2 mm.
  • the second magnetic member is advantageously arranged on the lock-body in an extremely advanced position.
  • This circumstance advantageously enables obviating the problems of the prior art, and in particular enables eliminating the magnetic disturbances induced by the ferromagnetic material with which the front portion of the lock-body can be made. Further, and advantageously, as the distance between the two magnetic organs is smaller, they are able to more effectively attract one another, ensuring that the system has a highly reliable operation.
  • the switch 5 is distinct and separated 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 is defined by a ferromagnetic member 10, preferably a pin, slidable between a blocked position, slidable between a blocked position, corresponding to the retained configuration of the closing means 4, and an unblocked position, corresponding to the release configuration of said closing means.
  • the ferromagnetic member 10 is preferably associated to an elastic recall member 11, typically a helical spring, which returns the ferromagnetic member 10 into the blocked condition, when the door or window leaf is dealigned from the frame, according to what will be more fully described in the following paragraphs.
  • an elastic recall member 11 typically a helical spring
  • the switch 5 and the second magnetic member 6 can be installed on a same support 12.
  • the presence of the support advantageously gives compactness to the closing system and simplifies the maintenance operations, as it is able to remove, with a single operation, both the functional elements of the lock-body, i.e. the switch and the second magnetic member.
  • the first magnetic member 3 is slidingly mobile between a retracted configuration ( figures 3A , 3F, 3G ) internally of a housing 2b of the counter-plate 2 and an extracted configuration ( figures 3B-3E ) from said housing, so as to near the switch 5.
  • the first magnetic member 3 when in the extracted configuration, is preferably in the resting configuration, including indirectly, against an edge surface that is a part of the lock-body, at the switch.
  • indirect contact it is meant that the first magnetic member can rest on the edge surface also by means of interpositioning of another member, for example a surface of a containing tray of the first magnetic member.
  • the first magnetic member 3 - when in the extracted configuration - is preferably in an indirect resting configuration against the front portion 20b of the lock-body 20 or, as illustrated in figures 3A-3G , against the support 12, at the switch 5.
  • the first magnetic member 3 is housed in a tray 35, so that an operating surface 3a of the first magnetic member 3 is in contact with a wall 35a of the tray destined to rest against the front portion of the lock-body 20.
  • recall means 8 are present for returning the first magnetic member 3 into the retracted configuration internally of 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.
  • the recall means 8 preferably comprise an elastic element 9.
  • the recall means comprise a ferromagnetic component conformed so as to exert a force of attraction on the first magnetic member of a smaller entity with respect to the force of attraction which the second magnetic member exerts on the first magnetic member, when the lock-body is proximal to the counter-plate.

  • Figure 3A shows the closing step of the door or window, when however the door or window leaf and the fixed frame are aligned and the lock-body 20 is therefore distal to the counter-plate 2.
  • the first magnetic member 3, on the side of the counter-plate 2 (side of the fixed frame), is held in the retracted configuration by the recall means 8, while on the lock-body 20 side (the door or window leaf side), the switch 5 does not interact with the first magnetic member 3 and maintains the closing means 4 in the retained configuration.
  • the switch 5 is defined by a ferromagnetic element 10 according to what is described in the foregoing, the element is in the blocked position, with an abutment portion 10a thereof defining a travel limit stop for the leverage 13 for activating the closing means 4.
  • Figure 3B shows the closing step of the door or window, when the door or window leaf and the fixed frame are aligned and the lock-body 20 is therefore facing the counter-plate 2.

  • the closing means automatically switch between the retained configuration, in which they are maintained internally of the lock-body 20, and the release configuration, in which they engage the counter-plate 2.
  • the switch 5 is defined by a ferromagnetic element 10 according to what is described in the foregoing, the element is in the unblocked position and therefore the leverage 13 can displace, causing release of the closing means, as illustrated in figure 3D .
  • the leverage 13 activates the release of the hook 4, which, on crossing an opening 3a of the lock-body 20, hooks the hooked portion 4b thereof to the portion 2a of the counter-plate 2.
