Abstract
Closing device adapted to close a door, tailgate, hatch, on one or more mutually distant closing points by actuating a retractable external handle forming a single block with the mechanism that converts the movement of the handle into actuation commands of one or more closing blocks. The device has the feature of preventing the engagement of the safety lock when the door is open.
Description
- 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, provided with one or more spaced apart closing points.
- In the field of closing devices and safety locks for doors and hatches, devices are available in the market which generally comprise a lock body, or mechanism adapted drive two remote locks, integrally applied to the inner side of the door or hatch concerned, and an actuation handle mounted at the lock body or mechanism on the outer side of the door or hatch. The movement of the external handle is transmitted to the internal components which release the lock.
- Said handle is further generally provided with a cylinder, or similar key locking means, which makes locking with a key possible.
- It is an object of the present Patent Application to introduce a closing device for doors and hatches, with particular reference to the doors and hatches of motor vehicles such as vans, caravans, motorhomes, and the like, which has greater simplicity and practicality of use with respect to the known closing devices.
- The invention achieves the object with a closing device comprising a handle block adapted to be integrally fastened on the outer side of a door, said handle block comprising a handle and a mechanism adapted to transform the motion of said handle into one or more translational motions for actuating one or more closing blocks. The mechanism comprises a first element for transferring the motion from said external handle to a control member of said closing blocks, which first motion transfer element is provided with three operating positions, in which:
- the first operating position is a standby position in which the first motion transfer element is in such a position that said first motion transfer element may interfere with a thrust member associated with the external handle when said external handle is moved in the opening direction of the door so that the motion of said member may be transmitted to the first motion transfer element and said motion transfer element may be positioned in the second operating position thereof;
- the second operating position is an opening position in which the first motion transfer element is in a position which corresponds to the driving in opening position of the closing blocks;
- the third operating position is a secure position in which the first motion transfer element is in such a position that it may not interfere with the member associated with the external handle when said external handle is moved in the opening direction of the door.
- Thereby, not only may be the motion of the handle transferred to one or more remote locking devices with respect to the handle itself, but it is also possible to use retractable handles forming a single block with the motion transformation mechanism and that rotate on an axis parallel to the plane of the door, thus also making the lock aesthetically pleasing in addition to more efficient and simpler to mount.
- In a particularly advantageous embodiment, the handle block comprises an anchoring lever which may be actuated on the side opposite to the external handle when the lock is mounted on the door, for example by means of a rod or a tie rod associated with an internal handle and/or a key cylinder accessible from the outer side, and a second element for transferring the motion from the anchoring lever to the first motion transfer element, the anchoring lever being configured to take on three operating positions, in which:
- the first operating position of the anchoring lever is a standby position in which the second motion transfer element is such as to ensure that the first motion transfer element is in the first operating position thereof;
- the second operating position of the anchoring lever is an opening position in which the second motion transfer element holds the first motion transfer element in the second operating position thereof;
- the third operating position of the anchoring lever is a secure position in which the second motion transfer element holds the first motion transfer element in the third operating position thereof.
- By virtue of these contrivances, opening the door may be controlled also from the inside, by using a remote handle with respect to the handle block and engaging a safety lock that may or may not be deactivated from the outside by means of the key cylinder, thus further increasing the flexibility and security of use.
- In another particularly advantageous embodiment, the engagement and/or disengagement of the safety lock may be electrically controlled through a motor integrated in the handle block.
- Further objects, features and advantages of the present invention will become more apparent from the following detailed description, provided by way of a non-limiting example and shown in the accompanying drawings, in which:
-
Figure 1 shows some views of a door with, applied, a closing device according to an embodiment of the present invention, comprising a handle block, two rods or cables and two closing blocks, in addition to an internal handle; -
Figures 2 to 5 show a section according to a plane parallel to the door and a corresponding side sectional view of the handle block inFigure 1 in a standby position (Figure 2 ), in an opening position by the internal handle (Figure 3 ), in an opening position by the external handle (Figure 4 ), with engaged safety lock (Figure 5 ), respectively. - With reference to
Figure 1 , a preferred embodiment of the present invention comprises: - a
handle block 10 adapted to be integrally fastened to adoor 15, saidhandle block 10 comprising anexternal handle 11 adapted to be positioned on the outside ofdoor 15 when in mounted position and a mechanism adapted to transform the motion of saidexternal handle 11 into one or more translational motions for actuating one ormore closing blocks 13 between a closing position and an opening position by means of acontrol member 16; - one or more rods or
cables 12 adapted to remotely transmit said translational motions, each of said rods orcables 12 being associated, at a first end, with thecontrol member 16; - one or
more closing blocks 13 adapted to be fastened todoor 15 and each associated with a second end of a rod orcable 12, saidclosing blocks 13 comprising reversible engagement means 14 with the frame ofdoor 15 which may be actuated by means of said rods orcables 12. - Said reversible engagement means 14 firmly remain anchored to the frame in the closing condition and pass into the opening condition by actuating the rods or the
cables 12, while the inverse passage, i.e., from the opening position to the closing position of said reversible engagement means 14, is obtained by closing the door without needing to act on the handle. - In the version shown in
Figure 1 , there is further present aninternal handle 36 connected to thehandle block 10 by means of a rod ortie rod 17 so it also acts on thecontrol member 16, as better detailed below. - In a preferred embodiment of the present invention, the reversible engagement means 14 of the
closing blocks 13 comprise an abutment or a plate to promote the engagement of saiddoor 15 with the frame. - In another preferred embodiment of the present invention, depicted in the accompanying drawings, there are two of said rods or
cables 12 and saidclosing blocks 13. The mechanism of thehandle block 10 is therefore adapted to transform the motion ofhandle 11 into two translational motions having opposite directions, transmitted by said rods orcables 12. Thehandle block 10 is arranged centrally with respect to the height ofdoor 15, close to the long side ofdoor 15 itself. The twoclosing blocks 13 are placed on opposite sides with respect to thehandle block 10. The rods orcables 12 are arranged parallel to the long side ofdoor 15. - The
external handle 11 preferably is of the retractable type and acts like a hinged lever so as to rotate on an axis parallel to the plane ofdoor 15 so as to translate the thrust member on a plane parallel to the plane ofdoor 15. The thrust member (shown inFigures 2 to 4 ) is depicted by anarm 18 provided with atransverse protrusion 19 adapted to interfere with acorresponding extension 20 of the release lever, indicated by 21 in the drawings. - Advantageously, the
external handle 11 may consist of a single block with the motion transformation mechanism of the handle itself. This allows the handle to be mounted in conjunction with the handle block, with apparent greater assembly simplicity. - The
handle block 10 may optionally comprise a key cylinder (not shown in the drawings) adapted to place the lock in secure status, as shown below. - The
internal handle 36 comprises agripping end 136 adapted to actuate a rod or atie rod 17 according to methods known to those skilled in the art. An example of commercial product is represented by article 1130 - handle for "ghost" internal lock - in the Applicant's catalog. - The opening movement of the
external handle 11 or theinternal handle 36 actuates thecontrol member 16 inside thehandle block 10, which is fastened at a first end of the two rods orcables 12, which pushes the two rods orcables 12 to translate in opposite directions so as to act, by means of the second end thereof, on theclosing blocks 13 and release theengagement members 14 from the frame ofdoor 15. - More in detail and with reference to
Figures 2 to 5 , theinternal handle 36 moves theanchoring lever 22 which is coupled by means of agear transmission 23 to anarm 24 which acts like a crank. Therelease lever 21 has aslotted end 25 in which apin 26 slides, associated withcrank 24 so as to provide a connecting rod/crank coupling with travel of the connectingrod 21 released from the travel ofcrank 24 when theanchoring lever 22 is in the standby position shown inFigure 2 . The standby position is a position in which the driving rods orcables 12 of theclosing blocks 13 are positioned so that theengagement members 14 of theclosing blocks 13 are engaged indoor 15 in closing position. In this position,slot 25 inlever 21 ensures that therelease lever 21 may translate both due to a rotation ofcrank 24 caused by the movement of theanchoring lever 22 from the standby position to the opening position, and due to a translation caused onextension 20 of therelease lever 21 by the abutment of theexternal handle 11 with thethrust member 19 when theexternal handle 11 is actuated to open. -
Figures 3 and4 show the lock in opening position following a movement of the internal handle (Figure 3 ) and of the external handle (Figure 4 ), respectively. As can be seen, therelease lever 21 is in the same position in both cases. This position is kept so long as the door remains open and theengagement members 14 are released from the frame ofdoor 15; indeed, with the door open, theengagement members 14 keep the cables orrods 12 in traction position and prevent thecontrol member 16 from returning to the standby position. In the case ofFigure 3 , the passage from the standby position to the opening position is determined by the rotation of theanchoring lever 22 by theinternal handle 36, which ensures thepin 26 ofcrank 24 drags therelease lever 21 in movement up to reaching the situation indicated inFigure 3 . In the case ofFigure 4 , it is the translation movement caused by theexternal handle 11 on thethrust member 19 and therefore, onextension 20, that causes the translation of therelease lever 21 in the same direction by virtue of the presence ofslot 25 which releasespin 26 from therelease lever 21 up to reaching the position shown inFigure 4 . - When the
anchoring lever 22 is moved from the standby position (Figure 2 ) to the secure position (Figure 5 ), thepin 26 ofcrank 24 causes a rotation of therelease lever 21 such as to prevent the abutment of thethrust member 19 of theexternal handle 11 withextension 20 of therelease lever 21. Thereby, opening the lock from the outside is prevented and theexternal handle 11 idly moves. - The
anchoring lever 22 may be moved into the secure position both by acting on theinternal handle 36 and on the key cylinder, when present. - The release lever 21 advantageously has such a shape to interfere with a blocking element when caused to move from the opening position to the secure position so that the direct passage from the opening position to the secure position is prevented unless the standby position is taken on first. In the embodiment shown in the drawings, such a blocking element comprises a tooth 27 (shown in
Figures 3 and4 ). Therelease lever 21 has such a shape to interfere with saidtooth 27 when therelease lever 21 is caused to rotate from a stroke-end position for opening the lock into secure position. - With regards to the
control member 16, it serves the function of transforming the motion of therelease lever 21, from the standby position to the opening position and vice versa, into a translational motion of the driving rods orcables 12 of theclosing blocks 13. Each rod orcable 12 is associated, at a first end, with thecontrol member 16 so as to move from a position of maximum extension to a position of minimum extension, and vice versa. - In the configuration shown in the drawings, the control member comprises a centrally
pivoted lever 16 with each of the two ends associated with a rod ortie rod 12 arranged at opposite sides of thehandle block 10 so that both rods orcables 12 translate in the same direction, but with opposite orientation so as to control a pair ofclosing blocks 13 of the door when thehandle block 10 is mounted in median position with respect to saidclosing blocks 13. - The
release lever 21 is hinged to thepivoted lever 16 of the control member. Thereby, the motion of therelease lever 21 is transferred to the control member and therefore, to the closing blocks by means of the rods orcables 12. - Overall, the operation of the lock according to the above-described embodiment is as follows.
- The
internal handle 36 moves the anchoringlever 22 which, through the transmission gears 23, actuates therelease lever 21, which in turn rotates thecontrol lever 16, also called cable lever in the present description. The pulling of thecables 12 moves the closing blocks which open the door (Figure 3 ). - The actuation of the
external handle 11moves lever 18, which drags therelease lever 21, which in turn rotates the cable lever 16 (Figure 4 ). - If the
internal handle 36 moves the anchoringlever 22 in the direction opposite to the opening one, this lever, through the transmission gears 23, rotates therelease lever 21 on the pivot provided by thecable lever 16. Therelease lever 21 thus leaves the actuation range of thehandle lever 18. In this condition, by acting on theexternal handle 11, thehandle lever 18 does not engage therelease lever 21 and the door is not opened (Figure 5 ). - Once opening is actuated, regardless of whether this happened from the internal side or from the external side, the
release lever 21 and thecable lever 16 remain in the stroke-end position shown inFigures 3 and4 . In this configuration, the system may not enter secure status (Figure 5 ) because the rotation of therelease lever 21 is prevented by thetooth 27 circled inFigure 3 . - Indeed, the
release lever 21 is designed to pass saidtooth 27 only if it is in the standby position (Figure 2 ), which will occur again oncedoor 15 is closed. This contrivance advantageously prevents the engagement of the safety lock when the door is open. - The description of the preferred embodiments of the invention above refers to the accompanying drawings. The same reference numbers in the various drawings identify the same elements or similar elements. The detailed description given above does not limit the scope of the disclosed invention because the scope of protection of the present invention is defined by the appended claims.
