Definitions

  • the present invention relates to a compact lock for internal doors, provided with mechanisms for opening/closing the lock and blocking and releasing the lock itself in the closure configuration without the use of keys.
  • the lock that is the subject of the present description is not, therefore, equipped with a through panel, but is of the so-said "split panel” type and can be made using both purely mechanical mechanisms and mechanisms based on the use of magnets.
  • the present invention also relates to a lock assembly comprising a lock provided with a magnet and a counter-plate, or staple, also provided with a magnet capable of co-operating with that of the lock.
  • Locks shaped in this way have the characteristic of creating a certain encumbrance on both sides of the door due to the presence of the keys, in that the latter are elements protruding from the lock.
  • This encumbrance in addition to being aesthetically displeasing, can give rise to safety problems, especially in those environments where children live, as they can accidentally bump such keys and, having a stature comparable to that of the height at which the lock is mounted in the door, the bumps can cause even serious damage to the face and to the eyes.
  • the "privacy" function is performed by elements, such as, for example, pegs, or small pins, provided with a tooth configured to co-operate with a handle pawl usually equipped with a special recess.
  • the "emergency" function is often performed by a tool external to the lock, such as for example a small screwdriver, with which the "privacy” element can be pushed into the lock release position by means of a small hole usually formed in the handle rosette. It is intuitable that, as in the case of an emergency, releasing the lock in this way may not be completely immediate or, in any case, not practicable with the necessary timeliness in certain dangerous situations.
  • the object of the present invention is, therefore, to provide a lock for internal doors that can be blocked in its closure configuration by means of mechanisms inside the lock itself so that there are no elements protruding from the same lock (e.g. keys, pins, pegs), beyond the optional handle.
  • a second object is, moreover, to provide a lock for internal doors that, once blocked, can be unblocked immediately and extremely easily in the event of an emergency.
  • This object is achieved by a lock comprising:
  • the user when a user wishes to block the opening of the lock, to another user who may be on the other side of the door, again by means of the first or the second handle, the user can rotate the first or the second pawl, respectively, in a second direction opposite to said first direction, so as to pass from the rest position to a second position of functioning, wherein the tooth of the one which, of the two pawls, has been made to rotate in the second direction, comes into contact with the ribbon spring connected to the interface element.
  • the user who manoeuvres the handle on the other side of the door with respect to the one where the user is who has enabled the block can unblock the lock by applying a greater force so that the tooth of the pawl controlled by the handle on the other side of the door pushes the interface element up to the point where it translates the interface element from its first to its second position and, then, opening the lock.
  • the block can be unblocked quickly and easily, ensuring maximum safety also for those users who, due to age or disability, may not be able to unblock the block themselves.
  • a third object that the present invention proposes to achieve is, therefore, the perfect coplanarity of the lock plus handle with the door.
  • a fourth object of the present invention is, therefore, to obtain greater design freedom for the manufacturer of frames, as regards shapes and thickness of the doors.
  • a fifth object of the present invention is, therefore, to allow easier and faster assembly of locks.
  • the lock of the present invention can also be made either by means of mechanical components alone, or by means of magnetic components.
  • the latch of the lock described here can be either a traditional slide latch or, a latch connected to a rocker arm which, in turn, co-operates with a magnet also mounted in the lock.
  • This magnet co-operates with a magnet having a magnetic polarization which is opposite with respect to a magnet contained in the staple mounted in the door jamb.
  • the magnet mounted in the lock is repelled by the magnet mounted in the staple towards the inside of the lock and the rocker arm performs a rotation which, in turn, causes the passage of the latch from the opening position to the closure position.
  • the lock of the present invention makes it possible to achieve a fourth object which is to obtain all the advantages described above together with the fluidity and robustness typical of magnetic locks.
  • the special feature of basing the closure mechanism not on the attraction of two magnets as, instead, occurs in the magnetic locks of the state of the art (utility model application no. 202007901498200 and patent applications nos. 102009901700267 , 102006901431400 , 102003901154929 and 102001900943841 ), allows exploiting of the advantages of fluidity linked to magnetism not only for the movement of the latch but also for the activation of other mechanisms that can be connected thereto such as, for example, anti-seismic systems, such as those provided for in patent application no. 102016000103226 .
  • a first embodiment of the lock (100) of the present invention comprises:
  • the case (110) can comprise a base (150) and a cover plate (151).
  • the base (150) can be delimited by at least one bottom surface (140) preferably parallel to the front (108) of the lock (100) and by two surfaces (141, 142) parallel one to the other and perpendicular to the bottom surface (140).
  • the case (110) can also be formed integrally with the front (108).
  • the base (150) is a plate consisting of a full solid provided with a recess (110') shaped in such a way as to accommodate in its interior the latch (107), the interface element (111), the first pawl (105) and the second pawl (106) and to allow the translation of the latch (107), the interface element (111) and the rotation of the first pawl (105) and the second pawl (106).
  • the interface element (111) is preferably equipped with a central body (132), with a first tooth (130), or front tooth, which protrudes from said central body (132), said first tooth (130) being placed between the front (108) of the lock (100) and the central body (132) of the interface element (111), and with a second tooth (131), or rear tooth, that protrudes from said central body (132), said second tooth (131) being placed between the central body (132) of the interface element (111) and the bottom surface (140).
  • the interface element (111) is translatable from a first position wherein only the front tooth (130) abuts on the profile of the recess (110') to a second position wherein only the rear tooth (131) abuts on the profile of the recess (110').
  • the interface element (111) is then equipped with a third tooth (133), or central tooth, placed between the first tooth (130) and the second tooth (131), and with a fourth tooth (134) placed between the first tooth (130) and the third tooth (133).
  • the third tooth (133) is configured to co-operate with the tooth (105') of the first pawl (105) and with the tooth (106') of the second pawl (106), to make the lock (100) move from the closure position to the opening position, when the first pawl (105) or the second pawl (106) is turned by handle.
  • the fourth tooth (134) is configured to co-operate with the latch (107) in such a way that when the interface element (111) moves from its first position to its second position, its fourth tooth (134) drags the latch (107) inside the case (110) of the lock (100), making it move from the closure position to the opening position, thus causing the opening of the same lock (100).
  • the spontaneous rotation of the first pawl (105) is prevented by a first spring (113) configured to co-operate with the protuberance (105") of said first pawl (105). Thanks to the presence of this first spring (113), maintaining of the first pawl (105) in its rest configuration is therefore guaranteed.
  • the spontaneous rotation of the second pawl (106) is prevented by a second spring (114) configured to co-operate with the protuberance (106") of said second pawl (106), guaranteeing the maintaining of the second pawl (106) in its rest configuration.
  • Both the first spring (113) and the second spring (114) are, preferably, ribbon springs.
  • the spontaneous translation of the interface element (111) from the first to the second position is prevented by a pair of permanent magnets (117, 118) consisting of a first magnet (117) mounted in the case (110) and a second magnet (118) mounted on the interface element (111), said first (117) and second (118) magnet having the same magnetic polarization and being aligned to the direction of translation of the interface element (111).
  • the same function performed by the pair of magnets (117, 118) which hold the interface element (111) immobile in its first position can, alternatively, be performed by a spring, not shown in the drawings, which restrains the front tooth (130) of the interface element (111) abutting on the profile of the recess (110') of the case (110).
  • the translation of the latch (107) from the closure position to the opening position is also prevented by a pair of permanent magnets (115, 116) consisting of a first magnet (115) mounted in the case (110) and a second magnet (116) mounted in the latch (107), said first (115) and second (116) magnet having the same magnetic polarization and being aligned to the direction of translation of the latch (107).
  • a pair of permanent magnets (115, 116) consisting of a first magnet (115) mounted in the case (110) and a second magnet (116) mounted in the latch (107), said first (115) and second (116) magnet having the same magnetic polarization and being aligned to the direction of translation of the latch (107).
  • the function performed by the pair of permanent magnets (115, 116) which hold the latch (107) immobile in the rest position can be performed by a spring.
  • the latch (107) When the door on which the lock (100) is mounted is brought closer to the jamb, the latch (107), at contact with the jamb, is pushed into the case (110) to then exit again, returning to its rest or closure position, when the door is aligned with the jamb.
  • the latch (107) thus entering the housing provided, which is normally provided for accommodating the latch (107) in common staples or counter-plates.
  • the opening of the lock (100), or rather the transition from the closing to the opening configuration, can also be performed with the second handle, i.e. with the rotation of the second pawl (106) in a manner wholly similar to what has already been described for the first pawl (106).
  • the tooth (106') of the second pawl (106) comes into contact with the central tooth (133) of the interface element (111) and causes the translation of the latter from its first to its second position, thus causing the latch (107) to retract into the case (110) and, therefore, the opening of the lock (100).
  • the first embodiment of the lock (100) of the present invention also comprises a spring (112) connected to the interface element (111).
  • Said spring (112) is also preferably a ribbon spring (112) and is configured to co-operate with the tooth (105') of the first pawl (105), and/or with the tooth (106') of the second pawl (106) in order to block the lock (100) in its closure position.
  • the first pawl (105) When the lock (100) is in its closure configuration, the first pawl (105) can be rotated in a second direction (anticlockwise direction for an observer of Figures 5a and 5b ), said second direction being opposite said first direction, so as to pass from the rest position to a second position of functioning, in which the tooth (105') of the first pawl (105) comes into contact with the ribbon spring (112) connected to the interface element (111). In this way, the lock (100) enters a blocking configuration, since if a user, who were to be found on the other side of the door on which the lock (100) is mounted (i.e.
  • the user who manoeuvres the second handle were to try to open the lock (100) by rotating the second pawl (106), in the first direction, from the rest position to the first position of functioning, they would not succeed in their intent because the translation of the interface element (111) from the first to the second position, and therefore the retracting of the latch (107), are prevented.
  • the user who manoeuvres the second handle and thus the second pawl (106) can unblock the lock (100) by applying a greater force so that the tooth (106') of the second pawl pushes the central tooth (133) of the interface element (111) to the extent of making the interface element (111) translate from its first to its second position.
  • the spring (112) connected with the interface element is configured to co-operate with the tooth (105') of the first pawl (105), when the first pawl (105) is rotated in a second direction, said second direction being opposite to said first direction, from the rest position to a second position of functioning, in such a way as to:
  • the second pawl (106) can optionally also be used to make the lock (100) enter the blocking configuration.
  • the second pawl (106) can be rotated in a second direction (anticlockwise direction for an observer of Figures 5a and 5b ), said second direction being opposite to said first direction, so as to pass from the rest position to a second position of functioning, in which the tooth (106') of the second pawl (106) comes into contact with the ribbon spring (112) connected to the interface element (111).
  • the lock (100) enters a blocking configuration, because if a user were to try to open the lock (100) by rotating the first pawl (105), in the first direction, from the rest position to the first position of functioning, they would not succeed in their intent because the translation of the interface element (111) from the first to the second position, and therefore the retracting of the latch (107), are prevented.
  • the user who manoeuvres the first handle and, therefore, the first pawl (105) can, however, unblock the lock (100) by applying greater force so that the tooth (105') of the first pawl pushes the central tooth (133) of the interface element (111) to the extent where it makes the interface element (111) translate from its first to its second position.
  • the translation of the interface element (111) then causes, thanks to the interaction of the tooth (134) of the interface element (111) with the latch (107), the translation of the latch (107) itself, and, therefore, the opening of the lock (100).
  • the spring (112) connected with the interface element is configured to co-operate with the tooth (106') of the second pawl (106), when the second pawl (106) is rotated in a second direction, said second direction being opposite to said first direction, from the rest position to a second position of functioning, in such a way as to:
  • a second embodiment of the lock (200) of the present invention comprises:
  • the case (210) can be formed integrally with the front (208) and comprises a cover plate (251) and a base (250).
  • the latter is a plate consisting of a full solid provided with a recess (210') shaped in such a way as to accommodate in its interior the latch (207), the magnet (219), the rocker arm (220), the interface element (211), the first pawl (205) and the second pawl (206).
  • Said recess (210') is also shaped in such a way as to allow the translation of the latch (207), of the interface element (211) and of the magnet (219), as well as the rotation of the first pawl (205), of the second pawl (206) and of the rocker arm (220).
  • the interface element (211) is provided with a central body (232), with a first tooth (230), or front tooth, a second tooth (231), or rear tooth and with a third tooth (233), or central tooth, placed between the first tooth (230) and the second tooth (231) and a fourth tooth (234) placed between the first tooth (230) and the second tooth (231).
  • the interface element (211) can be translated from a first position wherein the front tooth (230) abuts on the profile of the recess (210') to a second position wherein the rear tooth (231) abuts on the profile of the recess (210').
  • the third tooth (233) is then configured to co-operate with the tooth (205') of the first pawl (205) and with the tooth (206') of the second pawl (206), when the latter are rotated by means of a handle to move the lock (200) from the closure to the opening position.

  • the spontaneous translation of the interface element (211) from the first to the second position is prevented by a pair of permanent magnets (217, 218) consisting of a first magnet (217) mounted in the case (210) and a second magnet (218) mounted on the interface element (211), said first (217) and second (218) magnet having opposite magnetic polarization and being aligned to the direction of translation of the interface element (211).
  • the same function performed by the pair of magnets (217, 218) which hold the interface element (211) immobile in its first position can, alternatively, be performed by a spring, not shown in the drawings, which holds the rear tooth (231) of the interface element (211) away from the profile of the recess (210').
  • the translation of the latch (207) from the opening position to the closure position is prevented by a pair of permanent magnets (215, 216) consisting of a first magnet (215) mounted in the case (210) and a second magnet (216) mounted in the latch (207), said first (215) and second (116) magnet having opposite magnetic polarization and being aligned to the direction of translation of the latch (207).
  • a pair of permanent magnets (215, 216) consisting of a first magnet (215) mounted in the case (210) and a second magnet (216) mounted in the latch (207), said first (215) and second (116) magnet having opposite magnetic polarization and being aligned to the direction of translation of the latch (207).
  • the function performed by the pair of permanent magnets (215, 216) which holds the latch (207) immobile in the rest position can be performed by a spring.
  • the second embodiment of the lock (200) of the present invention must be coupled to a counter-plate (300) comprising a permanent magnet (301), or an electromagnet, having opposite magnetic polarization with respect to that of the magnet (219) of the lock (200).
  • the front (208) of the lock (200) and the front of the counter-plate, or staple, (300) are aligned and the magnet (219) mounted in the lock (200) is thus repelled by the magnet (301) mounted in the staple.
  • This repulsion causes the translation of the magnet (219) mounted in the lock (200) towards the interior of the case (210), and, that is to say, the moving away of the magnet (219) mounted on the lock (200) from the front (208).
  • the recess (210') of the case (210) is shaped in such a way as to allow this translation.
  • the rocker arm (220) is configured to co-operate with the magnet (219) mounted in the lock (200) in such a way that, when said magnet (219) translates inside the case (210), moving away from the front (208), the rocker arm (220) performs a rotation, the rotation of the rocker arm (220) causing, in turn, the move of the latch (207) from the opening position to the closure position.
  • the retracting of the magnet (219) mounted in the lock (200) therefore makes the rocker arm (220) rotate in anticlockwise direction for the observer of Figures 6a and 6b and, by rotating, pushes the latch (207) towards the exterior of the case (210), causing the lock (200) to close.
  • the magnet (219) mounted in the lock (200) can be either a permanent magnet or an electromagnet.
  • the opening of the lock (200) in its second embodiment can be performed by a user using a handle connected to the first (205) or to the second pawl (206) as already described above in relation to the first embodiment of the present invention.
  • a user wants to open the door by means of a handle, they can rotate the first pawl (205), or the second pawl (206), in a first direction (clockwise for an observer of Figure 7 ), making them move from the rest position to a first position of functioning wherein their tooth (205', 206') comes into contact with the central tooth (233) of the interface element (211).
  • the force exerted by the tooth (205') of the first pawl (205), or the tooth (206') of the second pawl (206), on the central tooth (233) of the interface element (211), causes the translation of the interface element from its first position to its second position.
  • the translation of the interface element (211) thanks to the interaction of the fourth tooth (234) of the interface element (211) with the latch (207), causes, in turn, the retracting of the latch (207) inside the case (207) with the consequent opening of the lock (200).
  • the second embodiment of the lock (200) of the present invention also comprises a ribbon spring (212) connected with the interface element (211) which exercises the function of blocking of the lock (200), together with the pawls (205, 206), said ribbon spring (212) being able to co-operate with the teeth (205', 206') of the pawls (205, 206) in order to block the lock (200) in its closure position.
  • the first pawl (205) can be rotated in a second direction (anticlockwise direction for an observer of Figures 8a and 8b ), said second direction being opposite to said first direction, so as to move from the rest position to a second position of functioning, wherein the tooth (205') of the first pawl (205) comes into contact with the ribbon spring (212) connected with the interface element (211).
  • the lock (200) enters a blocking configuration, since if a user, on the other side of the door on which the lock (200) is mounted (i.e.
  • the user who manoeuvres the second handle were to try to open the lock (200) by rotating the second pawl (206), in the first direction, from the rest position to the first position of functioning, they would not succeed in their intent, since the translation of the interface element (211) from the first to the second position, and therefore the retracting of the latch (207), are prevented.
  • the user who manoeuvres the second handle, and thus the second pawl (206) can unblock the lock (200) by applying a greater force so that the tooth (206') of the second pawl pushes the central tooth (233) of the interface element (211) to the extent of making the interface element (211) translate from its first to its second position.
  • the translation of the interface element (211) then causes, thanks to the interaction of the fourth tooth (234) of the interface element (211) with the latch (207), the opening of the lock (200).
  • the spring (212) connected with the interface element is configured to co-operate with the tooth (205') of the first pawl (205) when the first pawl (205) is rotated in a second direction, said second direction being opposite to said first direction, from the rest position to a second position of functioning, in such a way as to:
  • the second pawl (206) can optionally also be used to make the lock (200) enter the blocking configuration.
  • the releasing by means of the first pawl (205) can take place by applying a greater force so that the tooth (205') of the first pawl (205) pushes the interface element (211) to the extent of making it translate from its first to its second position, thus opening the lock (200).
  • the spring (212) connected with the interface element is, therefore, further configured to co-operate with the tooth (206') of the second pawl (206), when the second pawl (206) is rotated in a second direction, said second direction being opposite to said first direction, from the rest position to a second position of functioning, in such a way as to
  • a lock assembly (200, 300) comprising the second embodiment of the present invention (200) and a counter-plate (300) is also the subject of the present invention.
  • the counter-plate (300) comprises a magnet (301) having opposite magnetic polarization with respect to that of the magnet (219) of the lock (200).
  • This magnet (301) can be a permanent magnet (301) or an electromagnet, configured to co-operate with both a permanent magnet (219) and with an electromagnet mounted in the lock (200).
  • the lock assembly (200, 300) can therefore be implemented in four different embodiments.
  • the first embodiment of the assembly (200, 300) provides for the presence of two permanent magnets (219, 301) of which one (219) in the lock (200) and the other (301) in the counter-plate (300).
  • the second embodiment provides, instead, for the two electromagnets to be mounted, one in the lock (200) and the other in the counter-plate (300).
  • the third and the fourth embodiments then provide for the combination of a permanent magnet (219) in the lock (200) and an electromagnet in the counter-plate (300) and the combination of an electromagnet in the lock (200) and a permanent magnet (301) in the counter-plate (300), respectively.
  • a rotary handle 400
  • This handle (400) comprises: a fixed handle body, a movable ring or flange (402) and a knob (403).
  • the handle body comprises: a hollow cylindrical solid (404) derived from the difference of two solid cylinders (an inner cylinder and an outer cylinder) and an upper plate (404') in the form of a circular crown whose inner circumference coincides with the outer base circumference of the hollow cylinder (404).
  • the handle body is intended to be mounted in the door and on the lock (100, 200) in such a way that the hollow cylinder (404') is mounted in the thickness of the door and the upper plate (404') abuts on the door surface so as to become flush with it.
  • the movable flange (402) too comprises an upper surface having a shape of a circular crown and is configured to be mounted inside the hollow cylindrical solid (404) of the handle body and to slide inside it.
  • the movable flange (402) is, moreover, connected to the bottom (401) of the handle body by means of two springs (501, 502).
