Definitions
- the present invention relates to the field of closures and safety locks for doors and hatches; in greater detail, the present invention relates to the technical field of compression locks for doors, tailgates and hatches - in particular for motor vehicles, such as vans, caravans, camper vans and the like - provided with two or more distanced closing points.
- Locks of the compression type are particularly used in the fields of doors, tailgates and hatches installed on motor vehicles, such as vans, caravan, camper vans etc. Compression locks offer quick and secure closing where a certain resistance to vibrations is required and where seals are present.
- Document FR2937363 discloses an example of door lock based on a mechanism having a locking cylinder including a rotor rotatably mounted inside a stator.
- the cylinder has a blocking unit that is constituted of opposed lateral openings and opposed locks to block the rotor in rotation when the cylinder is spaced from a protecting cap placed inside opposed lateral ribs.
- the cylinder has a confining unit that confines a captive key in the rotor when mechanical units are spaced from one another.
- the locks maintain a bolt in unlocked position, for blocking the rotor in rotation by an eccentric drive.
- FR 690 981 A discloses an example of door lock according to the preamble of claim 1.
- the present invention thus describes a lock which is adapted to close, by compressing it, a door, a tailgate, a hatch, on two or more mutually distant closing points, by actuating only one handle.
- a preferred embodiment of the present invention comprises:
- the preferably "T"-shaped handle 11 of the device according to the present invention may be provided with a travel stop device and may comprise a cylinder lock adapted to control a stop sliding door bolt adapted to engage a specific housing on said handle block 10 in closing position.
- said closing blocks 13 are of the compression type and said reversible engagement means comprise a door bolt 16 adapted to rotate, so as to promote the engagement with the frame 14 of said door 15, and to translate in axial direction, orthogonal to the plane of the door 15, to achieve the successive fastening of the door 15.
- the mechanism of the handle block 10 is thus adapted to transform the rotational motion of said handle 11 into two translational motions having opposite directions, transmitted by said rods 12.
- the handle block 10 is centrally arranged with respect to the height of the door 15, near the long side of the door 15 itself.
- the two closing blocks 13 are placed on opposite sides with respect to the handle block 10.
- the rods 12 are arranged parallel to the long side of the door 15.
- belts or pulling cables can be advantageously employed to perform the same action of the rods 12 described herein: transforming the rotating movement of said handle 11 to a plurality of translational or linear movements, still according to methods widely known in the prior art.
- the handle block 10 comprises reversible engagement means with the frame 14 of said door 15.
- Said reversible engagement means preferably comprise a door bolt 26 adapted to rotate to engage the frame 14 of said door 15 and adapted to shift in axial direction, perpendicular to the surface of the door 15, to complete the closing of the door 15.
- the rotation of the handle 11 actuates the mechanism inside the handle block 10, fixed to a first end of the two rods 12, which pushes the two rods 12 to translate in opposite directions so as to act, by means of their second end, on the sliding door bolt of the two closing blocks 13.
- the action of the second end of the rods 12 rotates the sliding door bolt of the two closing blocks 13 firstly to promote the engagement with the frame 14 of said door 15 and then translate axially to press the door 15 onto its frame 14 and fasten the door 15 itself.
- the handle 11 rotates the door bolt 16 when it is actuated and its rotation starts.
- the door bolt 16 is in position substantially orthogonal to said rods 12 and to the long edge of the door 15, and thus such to interfere with the frame 14 of the door 15.
- the door bolt 16 still has a distance A from the plane of the door 15 onto which the two closing blocks 13 are fixed.
- a further rotation of the handle 11 to the end of travel does not apply further rotations to the door bolt 16, instead it applies an axial translation, orthogonal with respect to the plane of the door 15, such to reduce the distance between the door bolt 16 itself and the plane of the door 15 on which the two closing blocks 13 are fixed.
- This axial translation is adapted to progressively compress the door 15 onto its frame 14, guaranteeing the right squeezing of any seals placed on the edge of the door 15 or of the frame 14 and achieving the fastening of the door.
- the mechanism inside the closing block 13 may be provided according to the following preferred embodiment, shown in accompanying figures 5, 6 and 7 .
- Said mechanism comprises a shaft 19 having the rotation axis 20 substantially orthogonal to the plane of the door 15, and connected to said door bolt 16 by one end and to a toothed wheel 17, eccentric with respect to the axis of said shaft 19 and adapted to engage a rack 18 connected, in turn, to said second end of the rod 12, by the other end.
- the rotation of the handle 11 acts on the rod 12, which, in turn, actuates the rack 18, which, rotates the shaft 19 and thus the door bolt 16 by engaging the toothed wheel 17.
- the mechanism comprising the toothed wheel 17 and the rack 18 is such as to allow to minimize dimensions and to modulate the torque and rotation speed of the guiding shaft 19 of the door bolt 16.
- said toothed wheel is eccentric with respect to the axis 20 of said shaft 19 and, correspondingly, the rack 18 is oblique with respect to its direction of displacement, which is parallel to the rod 12, to the second end of which said rack 18 is integrally connected.
- the handle 11 when the door 15 is open, the handle 11 is in resting position and, correspondingly, no action is performed on the rods 12 or on the door bolts 16 of the closing blocks 13.
- the door bolts 16 are in position substantially parallel to said rods 12 and the long edge of the door 15, and thus such to interfere with the frame 14 of the door 15.
- the door bolt 16 In this position, the door bolt 16 has a distance A from the plane of the door 15 on which the two closing blocks 13 are fixed.
- the gear inside the closing blocks 13 is such that the toothed wheel 17 meshes at the tooth having the minimum distance from the axis of the shaft 19 with the initial part of the rack 18, closest to said second end of the rod 12 and closest to the axis 20 of the shaft 19.
- the rack 18 works near the axis of the shaft producing high speed and low torque.
- the door bolt 16 reaches its fastening position, substantially perpendicular to the long side of the door 15 and, then, the shaft 19 starts moving, dragging the door bolt 16, which may thus complete the fastening of the door 15 by compressing the seal placed on the edge of the door 15 or of the frame 14.
- a preferred embodiment of the closing block 13 comprises a so-called screwlock 21.
- Said screwlock 21 is associated with said shaft 19 - connected, in turn, to said door bolt 16 by a first end - and with said toothed wheel 17, eccentric with respect to the axis of said shaft 19, by a second end.
- the screwlock 21 is adapted to guide the shaft 19 therein, in a rotational and axially translatable manner, by means of a pin 22 adapted to engage both said shaft 19 and a guide 23 present on said screwlock 21.
- the screwlock 21 further comprises, in turn, an adjustment bushing 24 adapted to cooperate with said pin 22 and with said guide 23 so as to allow said screwlock 21 to rotate relatively to said shaft 19, while said shaft 19 translates axially.
- the handle block 10 comprises a mechanism similar to the one employed in the closing blocks 13 described above.
- Said mechanism comprises a screwlock 27 associated by a first end to the shaft 28 - connected, in turn, to a door bolt 26 - and by a second end to a first toothed wheel 29 and to a second toothed wheel 30.
- the screwlock 27 is adapted to guide the shaft 28 therein, in a rotational and axially translatable manner, by means of a pin 33 adapted to engage both said shaft 28 and a guide 34 present on said screwlock 27.
- the screwlock 27 further comprises, in turn, an adjustment bushing 35 adapted to cooperate with said pin 33 and with said guide 34 so as to allow said screwlock 27 to rotate relatively to said shaft 28, while said shaft 28 translates axially.
- the first toothed wheel 29 is adapted to engage with a pair of racks 31, 32, each connected to one end of said rods 12.

Description
- The present invention relates to the field of closures and safety locks for doors and hatches; in greater detail, the present invention relates to the technical field of compression locks for doors, tailgates and hatches - in particular for motor vehicles, such as vans, caravans, camper vans and the like - provided with two or more distanced closing points.
- Locks of the compression type are particularly used in the fields of doors, tailgates and hatches installed on motor vehicles, such as vans, caravan, camper vans etc. Compression locks offer quick and secure closing where a certain resistance to vibrations is required and where seals are present.
- However, in the case of doors with multiple closing points, the use of compression locks requires positioning a handle block at each closing point, to the detriment of simplicity and cost-effectiveness of the construction and of practicality of use.

Fig. 13 shows a section view of the handle block of an embodiment not describing part of the present invention. - With reference to the accompanying drawings, a preferred embodiment of the present invention comprises:
- .a
single handle block 10 adapted to be fixed to adoor 15, saidhandle block 10 comprising - .a
handle 11 associated with a mechanism adapted to transform the rotational motion of saidhandle 11 into a plurality of translational or linear motions according to methods widely known in the prior art; - .a plurality of
rods 12 adapted to transmit said translational motions at a distance, each of saidrods 12 being associated, at a first end, with said mechanism; - .a plurality of
closing blocks 13 adapted to be fixed to saiddoor 15 and each associated with a second end of arod 12 of said plurality ofrods 12, saidclosing blocks 13 comprising reversible engagement means with theframe 14 of saiddoor 15 which can be actuated by means of saidrods 12. - The preferably "T"-
shaped handle 11 of the device according to the present invention may be provided with a travel stop device and may comprise a cylinder lock adapted to control a stop sliding door bolt adapted to engage a specific housing on saidhandle block 10 in closing position. - In a preferred embodiment of the present invention, said
closing blocks 13 are of the compression type and said reversible engagement means comprise adoor bolt 16 adapted to rotate, so as to promote the engagement with theframe 14 of saiddoor 15, and to translate in axial direction, orthogonal to the plane of thedoor 15, to achieve the successive fastening of thedoor 15. - In another preferred embodiment of the present invention, shown in the accompanying
figures 1 - 4 , there are two of saidrods 12 and saidclosing blocks 13. The mechanism of thehandle block 10 is thus adapted to transform the rotational motion of saidhandle 11 into two translational motions having opposite directions, transmitted by saidrods 12. Thehandle block 10 is centrally arranged with respect to the height of thedoor 15, near the long side of thedoor 15 itself. The twoclosing blocks 13 are placed on opposite sides with respect to thehandle block 10. Therods 12 are arranged parallel to the long side of thedoor 15. - In lieu of said
rods 12, belts or pulling cables can be advantageously employed to perform the same action of therods 12 described herein: transforming the rotating movement of saidhandle 11 to a plurality of translational or linear movements, still according to methods widely known in the prior art. - In another preferred embodiment of the present invention, the
handle block 10 comprises reversible engagement means with theframe 14 of saiddoor 15. Said reversible engagement means preferably comprise adoor bolt 26 adapted to rotate to engage theframe 14 of saiddoor 15 and adapted to shift in axial direction, perpendicular to the surface of thedoor 15, to complete the closing of thedoor 15. - More in detail and with reference to accompanying
figures 2 ,3 and4 , the rotation of thehandle 11 actuates the mechanism inside thehandle block 10, fixed to a first end of the tworods 12, which pushes the tworods 12 to translate in opposite directions so as to act, by means of their second end, on the sliding door bolt of the twoclosing blocks 13. The action of the second end of therods 12 rotates the sliding door bolt of the twoclosing blocks 13 firstly to promote the engagement with theframe 14 of saiddoor 15 and then translate axially to press thedoor 15 onto itsframe 14 and fasten thedoor 15 itself. - In greater detail and with reference to accompanying
figure 2 , when thedoor 15 is open, thehandle 11 is in resting position and, correspondingly, no action is applied onto therods 12 and onto thedoor bolts 16 of the twoclosing blocks 13,door bolts 16 which are in position substantially parallel to saidrods 12 and to the long edge of thedoor 15, and such to not interfere with theframe 14 of thedoor 15. In this position, thedoor bolt 16 has a distance A from the plane of thedoor 15 on which the twoclosing blocks 13 are fixed. - With reference to accompanying
figure 3 , thehandle 11 rotates thedoor bolt 16 when it is actuated and its rotation starts. When the handle has performed approximately half of the available rotation, thedoor bolt 16 is in position substantially orthogonal to saidrods 12 and to the long edge of thedoor 15, and thus such to interfere with theframe 14 of thedoor 15. In this position, thedoor bolt 16 still has a distance A from the plane of thedoor 15 onto which the twoclosing blocks 13 are fixed. - At this point, with reference to accompanying
figure 4 , a further rotation of thehandle 11 to the end of travel does not apply further rotations to thedoor bolt 16, instead it applies an axial translation, orthogonal with respect to the plane of thedoor 15, such to reduce the distance between thedoor bolt 16 itself and the plane of thedoor 15 on which the twoclosing blocks 13 are fixed. This axial translation is adapted to progressively compress thedoor 15 onto itsframe 14, guaranteeing the right squeezing of any seals placed on the edge of thedoor 15 or of theframe 14 and achieving the fastening of the door. - The mechanism inside the
closing block 13 may be provided according to the following preferred embodiment, shown in accompanyingfigures 5, 6 and 7 . - Said mechanism comprises a
shaft 19 having therotation axis 20 substantially orthogonal to the plane of thedoor 15, and connected to saiddoor bolt 16 by one end and to atoothed wheel 17, eccentric with respect to the axis of saidshaft 19 and adapted to engage arack 18 connected, in turn, to said second end of therod 12, by the other end. - Therefore, the rotation of the
handle 11 acts on therod 12, which, in turn, actuates therack 18, which, rotates theshaft 19 and thus thedoor bolt 16 by engaging thetoothed wheel 17. - The mechanism comprising the
toothed wheel 17 and therack 18 is such as to allow to minimize dimensions and to modulate the torque and rotation speed of the guidingshaft 19 of thedoor bolt 16. - In a preferred embodiment of the present invention, said toothed wheel is eccentric with respect to the
axis 20 of saidshaft 19 and, correspondingly, therack 18 is oblique with respect to its direction of displacement, which is parallel to therod 12, to the second end of which saidrack 18 is integrally connected. - With reference to accompanying
figures 2 and5 , when thedoor 15 is open, thehandle 11 is in resting position and, correspondingly, no action is performed on therods 12 or on thedoor bolts 16 of theclosing blocks 13. Thedoor bolts 16 are in position substantially parallel to saidrods 12 and the long edge of thedoor 15, and thus such to interfere with theframe 14 of thedoor 15. In this position, thedoor bolt 16 has a distance A from the plane of thedoor 15 on which the twoclosing blocks 13 are fixed. Correspondingly, the gear inside theclosing blocks 13 is such that thetoothed wheel 17 meshes at the tooth having the minimum distance from the axis of theshaft 19 with the initial part of therack 18, closest to said second end of therod 12 and closest to theaxis 20 of theshaft 19. During this first rotation step, therack 18 works near the axis of the shaft producing high speed and low torque. - Continuing the rotation of the
handle 11, as shown in accompanyingfigure 6 , the distance between the action point of therack 18 on the profile of thetoothed wheel 17 and therotation axis 20 of theshaft 19 progressively increases, producing a reduction of the speed and a corresponding increase of the torque. - Finally, when the handle approaches its end of travel, the action point of the
rack 18 on the profile of thetoothed wheel 17 occurs at the points which are the most distant from theaxis 20, the speed transmitted to theshaft 19 is the lowest and the torque is the highest. - As a result, as the
handle 11 approaches it end of travel, thedoor bolt 16 reaches its fastening position, substantially perpendicular to the long side of thedoor 15 and, then, theshaft 19 starts moving, dragging thedoor bolt 16, which may thus complete the fastening of thedoor 15 by compressing the seal placed on the edge of thedoor 15 or of theframe 14. - With reference to accompanying
Fig. 8 , a preferred embodiment of theclosing block 13 according to the present invention comprises a so-calledscrewlock 21. Saidscrewlock 21 is associated with said shaft 19 - connected, in turn, to saiddoor bolt 16 by a first end - and with saidtoothed wheel 17, eccentric with respect to the axis of saidshaft 19, by a second end. - The
screwlock 21 is adapted to guide theshaft 19 therein, in a rotational and axially translatable manner, by means of apin 22 adapted to engage both saidshaft 19 and aguide 23 present on saidscrewlock 21. Thescrewlock 21 further comprises, in turn, anadjustment bushing 24 adapted to cooperate with saidpin 22 and with saidguide 23 so as to allow saidscrewlock 21 to rotate relatively to saidshaft 19, while saidshaft 19 translates axially. - In a further embodiment not describing part of the present invention and with reference to enclosed
Figures 9 - 13 , thehandle block 10 comprises a mechanism similar to the one employed in the closing blocks 13 described above. Said mechanism comprises ascrewlock 27 associated by a first end to the shaft 28 - connected, in turn, to a door bolt 26 - and by a second end to a firsttoothed wheel 29 and to a secondtoothed wheel 30. - The
screwlock 27 is adapted to guide theshaft 28 therein, in a rotational and axially translatable manner, by means of apin 33 adapted to engage both saidshaft 28 and aguide 34 present on saidscrewlock 27. Thescrewlock 27 further comprises, in turn, anadjustment bushing 35 adapted to cooperate with saidpin 33 and with saidguide 34 so as to allow saidscrewlock 27 to rotate relatively to saidshaft 28, while saidshaft 28 translates axially. - The first
toothed wheel 29 is adapted to engage with a pair ofracks rods 12. The secondtoothed wheel 30 is adapted to engage with a furthertoothed wheel 25 associated with thehandle 11 of saidhandle block 10 in a way to allow the transmission of rotation from thehandle 11 to theshaft 28. - Therefore, through the cooperation between the
toothed wheels handle 11 transmits a rotational movement to theshaft 28 adapted to move therods 12 and thedoor bolt 26 according to the operation described above with regards to theclosing block 13 wherein thedoor bolt 26 rotates and then translates axially in a way to complete the fastening of thedoor 15 by compressing the seal placed on the edge of thedoor 15 or of theframe 14. - The
handle 11 being connected to theshaft 28 through a pair oftoothed wheels toothed wheels - Furthermore, the pair of
toothed wheels handle 11 and saidhandle block 10, thus allowing adapting the lock according to the present invention to doors of various thickness. - The description of the embodiments above makes reference to the accompanying drawings. The same reference numbers in the various figures identify the same or similar elements.
