Definitions

  • the present invention relates to the field of closing devices and safety locks for doors and hatches; in greater detail, the present invention relates to the technical field of locks for doors, tailgates, and hatches, in particular for motor vehicles, such as vans, caravans, motorhomes and the like.
  • devices In the field of closing devices and safety locks for doors and hatches, devices generally comprising a lock body applied integrally to the concerned door, which houses a shaft, adapted to guide a closing sliding bolt integral with an end of said shaft, are available on the market.
  • a rotational actuating knob is associated with said shaft and is adapted to actuate it by rotating it and then translating it in an axial direction to close the rotational lock of the so-called "screw lock" type to which it belongs.
  • Said rotational knob is further generally provided with a cylinder lock, or similar key locking means, which makes locking with a key possible.
  • Patent document US 2014/284946 A1 discloses an example of a lever operated compression latch having an elongated, hook-ended pawl carrying a longitudinal slot, to be cam guided and pin rotated while translated to engage and withdraw from a keeper cup.
  • An example of a lock of the compression type used for doors and hatches is known from EP 3 287 578 A1 .
  • the invention achieves the purpose with a lock according to claim 1, adapted to close, by compression, a door, a tailgate, a hatch, comprising a handle block adapted to be integrally fixed to the outer side of a door, said handle block comprising a handle associated with a rotor and adapted to rotate on an axis parallel to the plane of the door from a first position to a second position, wherein said first position corresponds to a closing position of said lock and said second position corresponds to an opening position of said lock.
  • the handle block is engaged by means of the rotor to a closing block adapted to be integrally fixed onto the inner side of said door and comprises reversible engagement means with the door frame.
  • the reversible engagement means comprise a bolt adapted to rotate to promote the engagement with the frame of said door and to translate in an axial direction to successively fasten the door.
  • the reversible engagement means actuated by the handle, through a kinematic mechanism, convert the rotary motion of the rotor into a compound motion comprising, in sequence:
  • the reversible engagement means comprise a shaft connected at one end to the bolt, the other end being coupled to the kinematic mechanism so that the shaft can both rotate and translate axially allowing the bolt to perform a corresponding roto-translation.
  • the closing device of the present invention can be applied to the doors of vans, caravans, motorhomes, and the like and is characterized as an improvement of the conventional "screw lock" devices which perform both the closing and fastening by means of a simple continuous rotary movement of the handle which occurs on an axis parallel to the plane of the door.
  • the lock according to the invention also with doors, hatches, flaps provided with multiple locking points, because the possibility is envisaged, in an advantageous improvement, to generate additional translatory motions to the roto-translatory motion acting on the main bolt included in the lock body to drive remote locking blocks by means of rods or tie-rods, thus achieving an effective compression closing through the use of a single handle.
  • a preferred embodiment of the present invention comprises a handle block 10, adapted to be integrally fixed to the outer side of a door, comprising a handle 11 associated with a rotor 111, engaged with a closing block 20 adapted to be integrally fixed to the inner side of the door at the handle block 10 and comprising a shaft 19 and a bolt 16.
  • the handle block 10 may be provided with a limit stop device and may comprise a cylinder lock adapted to control a stop bolt adapted to engage, in the closing position, with an appropriate housing on the handle 11, said handle 11 being preferably of the retractable type.
  • Fig. 1b shows the handle 11 in a first position flush with the door while Fig. 4b shows the handle 11 in a second position substantially at 90° to the first position.
  • the first position corresponds to a closing position of the lock while the second position corresponds to an opening position of the lock.
  • the handle block 10 comprises reversible means adapted to transform the rotational motion of the handle 11, which occurs on an axis parallel to the plane of the door, into a rotational motion of the rotor 111, which occurs on an axis perpendicular to the plane of the door.
  • reversible means may comprise a connecting rod/crank coupling 113 as shown in Fig. 8 .
  • the rotor 111 moves the closing block 20.
  • the handle block 10 and the closing block 20 are typically two separate devices, but can also be advantageously integrated into the same lock component.
  • the closing block 20 comprises reversible engagement means with the door frame that advantageously comprise an element 16, named a bolt, adapted to rotate by means of a shaft 19 fixed at one end to facilitate engagement with the door frame 14 of the door.
  • the bolt 16 moves from an opening position, in which it is substantially parallel to the perimeter edge of the door frame 14 as shown in Figs. 4d and 4e to a closing position in which the bolt 16 is rotated substantially 90° to a position substantially perpendicular to the perimeter edge of the door frame 14 as shown in Fig. 3e .
  • the shaft 19 can translate in the axial direction.
  • the door is fastened by moving the shaft 19 axially in the approaching direction of the bolt 16 to the lock body 10.
  • the bolt 16 rotates firstly to promote the engagement with the frame 14 of said door and then translates axially to press the door onto its frame 14 and fasten the door itself.
  • a further rotation of the handle 11 to the limit stop does not apply further rotations to the bolt 16, instead, it applies an axial translation, orthogonal to the plane of the door, such to reduce the distance between the bolt 16 itself and the plane of the door on which the closing block 20 is fixed.
  • This axial translation is adapted to progressively compress the door onto its frame 14, guaranteeing the right squeezing of the seals possibly placed on the edge of the door or of the frame 14 and achieving the fastening of the door.
  • the door is opened by performing the same steps in reverse.
  • the initial rotation of the handle 11 in the opposite direction causes the axial translation of the bolt 16 so that the distance between the bolt and the door is increased.
  • the successive rotation in the same direction induces rotation of the bolt 16, which thus disengages from the frame 14.
  • STEP 3 and STEP 4 are sequential and nothing is felt on the handle, the decompression and rotation of the bolt occur in a single movement that starts at angle A and arrives at angle C.
  • the closing and compression of the seals are accomplished by closing the hatch and pushing the handle 11 into the handle block 10.
  • the insertion of the safety device can take place with any position of the handle, if this is open at the next closing it will lock in the position of step 1.
  • the reversible engagement means are advantageously driven by the handle 11 which, by means of a kinematic mechanism, converts the rotary motion of said handle, which takes place on an axis parallel to the plane of the door, into a rotary motion of the rotor 111, which takes place on an axis perpendicular to the plane of the door.
  • the rotor 111 is engaged with the closing block 20 which, through a kinematic mechanism, converts said rotational motion into a compound motion comprising, in sequence:
  • the handle 11 typically moves within a circular sector defined by a predetermined release angle (A) relative to its angular resting position corresponding to the closing of the lock which corresponds an absence of motion of the shaft 19.
  • the conversion of the rotational motion of the closing block 20, may be advantageously performed by means of a cam device which moves on a cam guide so that there is no simultaneous roto-translation of the shaft 19, but the rotational and translatory motions of the shaft 19 occur in a defined time succession.
  • Fig. 5 shows a solution which employs a screwlock 21 adapted to guide the shaft 19 inside, in a rotational and axially translatable manner, by means of a pin 22 adapted to engage both with said shaft 19 and said guide 23 present on said screwlock 21, said screwlock 21 further comprising an adjustment bushing 24 adapted to cooperate with said pin 22 and with said guide 23 to allow said screwlock 21 to rotate relatively to said shaft 19, while said shaft 19 translates axially.
  • the lock according to the invention is particularly advantageous when the door, tailgate, or hatch to which it is applied requires more than one locking point.
  • a variant envisages the use of a kinematic mechanism adapted to transform the motion of the handle 11 into one or more further translatory motions transverse to the translatory motion of the bolt 16 to allow said translatory motions to be remotely transmitted to one or more closing blocks 13 by means of one or more rods or tie-rods 12.
  • the kinematic mechanism may advantageously comprise a gear and one or more racks associated with one or more levers 17 so that the rotation of the gear causes the translation of said one or more levers.
  • the further translatory motions are advantageously transferred to a pair of levers 17 arranged on the opposite sides of the closing block 20, which levers 17 are configured to move in the same transverse direction relative to the axial motion of the bolt 16, but with opposite orientations.
  • the lock comprises:
  • the reversible engagement means of the closing locks 13 typically comprise, like the closing assembly 20, a bolt 16' adapted to rotate to promote the engagement with the frame 14 of said door, and to translate in an axial direction, to carry out the successive fastening of the door.
  • the closing blocks 13 each comprise a shaft having the rotation axis 25 substantially orthogonal to the plane of the door, and connected with an end to said sliding door bolt 16' and with the other end to a toothed wheel 17, e.g., eccentric relative to the axis of said shaft and adapted to engage with a rack 18 connected, in turn, to said second end of the rod 12.
  • a same screwlock configuration can convert the rotational motion of the toothed wheel to roto-translatory motion of the bolt in a manner similar to that seen for the bolt of the handle assembly.
