AUXILIARY LOCKING DEVICE FOR SLIDING DOORS OR HINGED DOORS AND THE LIKE FOR APPLICATIONS IN MOTOR VEHICLES

Description

BACKGROUND ART OF THE INVENTION

Field of application

[0001] The present invention relates to a locking device of sliding or hinged doors and the like, for applications in motor vehicles. In greater detail, the invention relates to a locking device of cargo doors of a commercial motor vehicle that can be used to prevent the unauthorized opening thereof, in addition to the standard lock.

Prior art

[0002] In the field of commercial motor vehicles, whether they are sliding or hinged, the cargo doors for accessing the loading receptacles of the motor vehicle comprise standard locks which in many cases are easy to force open, thus not being suitable for preventing unauthorized access to the loading receptacles.

[0003] Nowadays, various types of devices or locks for locking the cargo doors of commercial motor vehicles are very common. Such known locking devices may be purchased separately to be fixed to the cargo doors of the motor vehicles, in addition to standard locks.

[0004] A locking device for doors, for example hinged or sliding doors, for commercial motor vehicles of known type typically consists of a lock which comprises, inside a casing, a corresponding mechanism operable by a key that can be inserted into a keyhole arranged on the lock. Such a mechanism comprises a traditional lock which allows the activation of a bolt.

[0005] Such a known lock of the locking device is configured to mechanically act in conjunction with a locking element of the bolt, which is separate from the lock, to ensure the closing of the door. In particular, both the lock and such a locking element of the bolt are each fixed on a respective leaf of the door by means of fixing means so that when the leaves are in the closed position, the bolt of the lock can be inserted into a seat of the locking elements, for example by operating the key. Thereby, any relative movement between the lock and the locking element of the bolt are prevented, thus ensuring that the door remains closed.

[0006] Such a known door locking device using a bolt has the drawback of always requiring a key to control the insertion of the bolt into the seat of the locking element and to lock the door in closed position.

[0007] Moreover, since the movable bolt is included in the lock of the locking device, known systems adapted to release the device from the inside of the motor vehicle under emergency conditions and to allow the opening of the door are usually associated with the lock because they are configured to act on the bolt to release it. This causes certain drawbacks for making and implementing such emergency opening systems of the door since the lock of the device is usually fixed on the leaf of the door which is opened most often. Indeed, the case may occur in which the emergency opening mechanism of the cargo door of the motor vehicle, and particularly of sliding type, may get caught or otherwise interfere with the fixed portion of the lock applied.

[0008] Document EP2995754 A1 discloses an auxiliary device for opening and closing the loading compartment of a motor vehicle, which can be installed on the back door of the vehicle. Document ES1076172 U discloses a closing for a delivery vehicle.

SUMMARY OF THE INVENTION

[0009] The object of the present invention is to propose a locking device of sliding or hinged doors and the like, for applications in motor vehicles, in particular in commercial motor vehicles, which allows the drawbacks indicated above with reference to the known art described to be overcome.

[0010] A further task of the invention is to provide a locking device for the doors of a motor vehicle comprising contrivances which make it particularly suitable for resisting attempts of forced entry.

[0011] A further task of the invention is to provide a locking device for the doors of a motor vehicle configured to accommodate different types of lock cylinders to meet different needs of use, including at least one suitable for performing the function of "hold open".

[0012] Such objects and tasks are achieved by a locking device for doors of motor vehicles, particularly for sliding doors or hinged doors, as defined by appended claim 1.

[0013] Preferred embodiments of such a door locking device are defined by the dependent claims.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0015] With reference to the aforesaid figures 1 to 7, a locking device for doors of motor vehicles, in particular sliding doors or hinged doors, according to the invention is indicated as a whole with numeral 100.

[0016] The door locking device of the invention can be used in particular to lock the cargo doors of a commercial motor vehicle under closed conditions, in addition to a standard lock, thus preventing the unauthorized opening of such cargo doors and access to the loading receptacle of the motor vehicle.

[0017] Later in the description, the locking device 100 for doors of motor vehicles will also be indicated as locking device or more simply as device.

[0018] With reference to the drawings, the door locking device 100 comprises a lock 10 adapted to be fixed to a first leaf element 50 of the door. Such a lock 10 consists of a casing 1 for accommodating a lock unit 2 which is operable by a key (not shown) that can be inserted into a keyhole 2a prepared in casing 1.

[0019] Such a casing 1 is hemispherical- or cap-shaped with a circular base portion 1a. Such a casing 1 is made of metal material, preferably steel with heat tempering processing to reach a specific degree of hardness HRC 52-54. It is worth noting that due to the cap shape of casing 1 and to the material used to make it, the locking device 100 of the invention ensures an increased resistance to attempts of forced entry both with sharp bodies and with cutting and drilling equipment.

[0020] With reference to figures 2 to 3, the above-mentioned lock unit 2 of the locking device 100 is accommodated in casing 1 along a first axis Z (shown with a dotted line in the drawings) which is orthogonal to a base 4 for fixing lock 10 to the first leaf element 50 of the door. Such a lock unit 2 is operable to control a disc element 3 for opening/closing the locking device 100 and is positioned coaxial to said lock unit 2 to rotate between an open position and a closed position of the device, and vice versa. In other words, the opening/closing disc element 3 operates as a rotating lock bolt of the locking device 100 of the invention. Such a disc element 3 radially extends from the first axis Z and comprises a through hole 3a for the insertion of an actuation end 11' of a cylinder unit 11 or first cylinder unit of the lock unit 2.

[0021] In one example embodiment, the disc element 3 comprises a first arc-shaped engagement surface 3b and a first 3c and a second 3d protruding tooth operating as end stop elements in the rotation of the disc element 3, as will be clarified below.

[0022] In a first embodiment, the aforesaid lock unit 2 comprises a first 12 and a second 13 portion of container/adapter of the cylinder unit 11 both having a substantially circular section. Such first 12 and second 13 container portion may be coupled with each other to accommodate the cylinder unit 11 itself, thus forming a first adapter 12-13.

[0023] Moreover, a toroidal-shaped gasket 14, for example made of Teflon, is interposed between the second container portion 13 of the cylinder unit and the disc element 3.

[0024] A further gasket 14' is interposed between the cylinder unit 11 and the disc element 3.

[0025] Moreover, the lock unit 2 comprises protection elements 15, 16, 17 of the cylinder unit 11 interposed between keyhole 2a and the first container portion 12 of the cylinder unit. Such protection elements, of type known to a person skilled in the art, materialize in a defender element 15 and in dust covers 17 operable by springs (not shown) to interact with a respective cover 16. As is known, dust covers, which may be applied on certain types of lock cylinders, have the advantage of avoiding foreign bodies (e.g. dust, water, etc.) from getting inside cylinder 11 once the key is extracted from the lock, thus compromising the correct operation thereof.

[0026] Moreover, with reference to figure 1, the fixing base 4 of lock 10 includes a base sheet 6 fixed to casing 1 by means of first screws 7, in particular four screws. Such a base sheet 6 overlaps and is restrained to an undercut plate 5, which in turn may be fixed to the first leaf element 50 of the door of the motor vehicle by means of second screws 9. Respective third screws 8, in particular two screws, can be inserted into through holes 5a, 6a of the undercut plate 5 and of the base sheet 6, respectively, to ensure a solid fixing of lock 10 to the door of the motor vehicle.

[0027] The locking device 100 of the invention further comprises a locking element 20 of the disc element 3, configured to be fixed to a second leaf element 51 of the door of the motor vehicle.

[0028] Such a locking element 20 is configured to mechanically act in conjunction with the disc element 3 of lock 10 when the door is in a closed configuration, as shown in figure 2. In such a closed configuration of the door, the locking element 20 is inserted in a respective compartment 19 prepared in the hemispherical casing 1 of lock 10.

[0029] In particular, the locking element 20 comprises an engagement unit 21 shaped to delimit a seat 22 adapted to be engaged with the disc element 3 in closed position to prevent any relative movement between lock 10 and the locking element 20 in the closed configuration of the door.

[0030] In a preferred embodiment, the engagement unit of the locking element 20 comprises a hook 21 which is rotatable about a second axis Y orthogonal to the first axis Z of casing 1, from a resting position to a disengaged position. In such a disengaged position, shown in figure 4, hook 21 disengages the disc element 3 by opening the locking device 100 under emergency condition.

[0031] Advantageously, with reference to figures 2 to 4, the locking element 20 comprises manually-operated means 23 configured to operate the rotation of hook 21 about the second axis Y, from the resting position to the disengaged position to release the locking device 100 without using a key.

[0032] In greater detail, such means for operating the rotation of hook 21 consist of a cable 24, for example made of steel, having a first end 24a fixed to a head portion 25 of hook 21 and a second free end 24b which is manually operable from inside the motor vehicle under the emergency condition.

[0033] In addition, with reference to figure 6, the locking element 20 comprises elastic means 26, for example one or more springs, associated with hook 21. Such elastic means 26 are configured to elastically rotate hook 21 from the disengaged position to the resting position following the ceasing of the action executed with the manually-operated means.
For example, the aforesaid elastic means 26 materialize in a torsion spring or a compression spring.

[0034] In a preferred embodiment, the head portion 25 of hook 21 of the locking element 20 comprises a tilted contact and sliding surface 27 adapted to be engaged by the corresponding engagement surface 3b of the disc element 3 rotated in closed position. In particular, the engagement of the first surface 3b of the disc element 3 on the tilted surface 27 of hook 21 causes the rotation of hook 21 itself from the resting position, contrasting the action of the elastic means 26, away from the disc itself. Such a rotation is sufficient to engage the disc element 3 in the seat 22 of hook 21 to lock the door in closed position (figure 2).

[0035] In order to release device 100 and open the door from such a closed position of the door, there is a need to rotate the disc element, by means of a key, by 90°, from the closed position to the open position (figure 3) to bring device 100 from the locked configuration to the released configuration.

[0036] Generally, the key may only be extracted from the cylinder unit 11 in the locked position of device 100.

[0037] In a preferred embodiment, with reference to figures 1, 6 and 7, the rotatable hook 21 is fixed, for example by means of a pin 35, to a semi-circular plate 28 for fixing the .locking element 20 to the second leaf element 51 of the door.

[0038] It is worth noting that such a plate 28 comprises parallel ribs 37 for the insertion of the pin 35 of hook 21 adapted to act in conjunction with a closing element 36 to delimit a rotation compartment 38 for hook 21. It is worth noting that plate 28 and the closing element 36 simultaneously may be fixed to each other and to the second leaf element 52 of the door by means of bolts 39 (shown in figure 1).

[0039] Advantageously, the fixing plate 28 includes first 29 and second 30 security means adapted to hinder attempts to tamper with the device and/or unauthorized opening.

[0040] In particular, the first security means comprise ribs 29 arranged on a circumferential portion of the fixing plate 28 for the protection of hook 21.

[0041] The second security means comprise a tubular conduit 30 made in one piece with the fixing plate 28 and which extends from said fixing plate away from hook 21. Such a tubular conduit 30, which is in communication with the rotation compartment 38 of hook 21, is configured to promote the insertion and the protection of the release cable 24 in an emergency of device 100 (figure 7).

[0042] Such security means 29, 30 make it difficult to reach both hook 21 and the security cable 24 from the outside of device 100 in order to operate the hook in an emergency and therefore they hinder all attempts to force open and release device 100.

[0043] It is worth noting that the cap-shaped casing 1 of device 100 is shaped so as to accommodate various types of cylinder units with the related containers or adapters.

[0044] It is worth noting that the lock unit 2 in figure 1 comprises the first cylinder unit 11 which is operable by a flat key (not depicted).

[0045] Figure 8 shows a perspective and exploded view of a second example embodiment of the key-operated lock unit 2' that can be used in the locking device 100 of the invention.
Such a second lock unit 2' comprises a respective cylinder unit 111 or second cylinder unit which is operable by a tubular key 112 to act on a control element 115 of the lock unit 2'. Such a second cylinder unit 111 can be inserted into a second container or adapter 113 to be accommodated in casing 1.

[0046] Moreover, a respective toroidal-shaped gasket 114, for example made of Teflon, is interposed between the second container/adapter 113 of the second cylinder unit and the disc element 3'.

[0047] A head gasket 114a is positioned close to an opening 113a for inserting the second cylinder unit 111 into the second adapter 113.

[0048] The control element 115 comprises an actuation end 115' which can be inserted into the through hole 3a of the disc element 3'. It is worth noting that the disc element 3' comprises the first engagement surface 3b similar to the one of disc 3 in figure 1, but does not have protruding end stop teeth.

[0049] It is worth noting that with the above-described second cylinder unit 111 with tubular key 112, the device 100 of the invention advantageously implements the function of "hold open", known to a person skilled in the art. With such a function, the key may be extracted both in closed lock position and in open lock position in order to meet various needs of use. In other words, the disc element 3' may be locked in open position and key 112 may be extracted from cylinder 111.

[0050] Figure 9 shows a perspective and exploded view of a third example embodiment of the key-operated lock unit 2" that can be used in the locking device 100 of the invention.

[0051] Such a third lock unit 2" comprises a third cylinder unit 211, in particular a double cylinder, which is operable by a key (not shown). Such a double cylinder 211 has an actuation end 211' which can be inserted into the through hole 3a of the disc element 3.

[0052] Such a disc element 3 is similar to the one described with reference to figure 1.

[0053] Such a double cylinder 211 can be inserted into a respective container/adapter 213 or third adapter having U-shaped cross section to be accommodated in casing 1.

[0054] Moreover, a respective U-shaped gasket 214, for example made of Teflon, is interposed between the third container/adapter 213 of the cylinder and the disc element 3.

[0055] Additionally, a unit 215 for protecting the double cylinder 211 comprises a defender 215a fixed to a cover 215b between which a membrane 215c, for example a silicone resin membrane, and a respective head gasket 214a are interposed.

[0056] With reference to figure 10, an inner structure of the cap-shaped casing 1 configured to accommodate the various above-mentioned lock units 2, 2', 2" is described in greater detail.

[0057] In particular, casing 1 comprises a through hole 80 in communication with keyhole 2a and configured to accommodate the three types of lock units 2, 2', 2", that is the first 11, the second 111 and the third 211 cylinder unit inserted in the first 12-13, in the second 113 and in the third 213 container/adapter, respectively.

[0058] In greater detail, the hole 80 is delimited by a first wall 81 connected to an inner wall 82 of casing 1 through radial ribs 83. The aforesaid first wall 81 of hole 80 comprises canals 84, in particular four canals, which are coaxial to the aforesaid hole 80. Such canals 84 are configured to engage longitudinal ribs 85 prepared on an outer surface S, S', S'' of the first 12-13, of the second 113 and of the third 213 adapter, respectively.

[0059] In particular, such longitudinal ribs 85 allow to insert and keep in position the first adapter 12-13 of the first cylinder 11 (shown in figure 1) in hole 80.

[0060] Moreover, the through hole 80 comprises a first 86 and a second 87 compartment which radially extend from the aforesaid hole 80 along a same main direction or first direction and in opposite direction.

[0061] In greater detail, the above-mentioned second adapter element 113 of the second cylinder unit 111 comprises a protruding portion 88, with a rectangular cross section, prepared on the outer surface S' of such a second adapter element and configured to be housed in the first compartment 86.

[0062] In other words, providing such a first compartment 86 advantageously allows to insert and keep in position the second adapter element 113 of the second cylinder 111 in the hole 80 of casing 1.

[0063] Moreover, the third locking cylinder 211 of the above-described lock unit 2" housed in the third adapter element 213 comprises a first protruding portion 89 configured to be housed in the second compartment 87. In other words, providing such a second compartment 87 advantageously allows to insert and keep in position the third cylinder 211, with the related adapter 213, in the hole 80 of casing 1.

[0064] Moreover, one of the above-mentioned radial ribs 83 of casing 1 comprises a raised element 90 configured to abut with the protruding teeth 3c and 3d of the disc element 3 by acting as end stop for the rotation of such a disc element.

[0065] It is worth noting that all the components of the locking element 20 of the locking device 100 and all the fixing means used in the device are made of metal material, preferably o.f stainless steel, to ensure an increased resistance to oxidization.

[0066] Preferably, defender 15, 215a of the cylinder unit 11, 211 has the same features as the cap-shaped casing 1 in terms of materials used for the manufacturing thereof.

[0067] As noted above, the locking device 100 for doors of motor vehicles of the invention has several advantages with respect to known solutions and perfectly achieves the set objects.

[0068] In particular, with the locking device 100, there is no need to use the key to lock the door in closed position. Indeed, following the movement of the first leaf element 50 to bring the door of the motor vehicle to the closed position, due to the shape of the head portion 25 of the rotatable hook 21, the disc element 3, which is already in closed position, engages the contact and sliding surface 27 of such a head portion 25, thus causing the rotation of hook 21 away from the disc itself. Such a rotation is sufficient to engage the disc in seat 22 of the hook to lock the door in closed position. Moreover, with the device of the invention, there is no need to use a mechanism with a "quick release" movement.

[0069] Moreover, unlike known solutions, the locking device 100 for doors of motor vehicles of the invention does not have the drawbacks for making and implementing emergency opening systems of the door since such systems in device 100 are associated with the locking element 20 and not with the lock 10.

[0070] Moreover, as described above, the locking device 100 of the doors of a motor vehicle comprises security means associated with the locking element 20 which prevent the opening of the device with skill, for example by introducing foreign bodies to cause a rotation of hook 21. Such security means therefore make the door locking device 100 of the invention suitable for resisting attempts of forced entry and tampering.

[0071] Moreover, device 100 is configured to accommodate different types of lock cylinders to meet different needs of use, among them one suitable for performing the function of "hold open".

[0072] Those skilled in the art may make several changes and adaptations to the embodiments of the locking device for doors of motor vehicles of the invention, and may replace elements with others which are functionally equivalent in order to meet contingent needs, without departing from the scope of the invention as defined by the appended claims.
