Definitions

  • the present invention relates to a lock, particularly for doors of vehicles of the type of vans, trucks, semi-trailer trucks and the like.
  • such locks comprise a box-like body that can be fixed to the door of the vehicle and to which an actuation lever is pivoted about a substantially vertical axis, in order to permit its movement from a closed configuration of the lock to an open configuration (in order to enable access to the compartment of the vehicle closed by the door), and vice versa.
  • Actuation of the lever, for opening the lock causes the shifting of a pin (in a direction parallel to the door) contained in the box-like body, and the consequent disengagement of a spring latch, associated with the pin, from a corresponding seat, in order to allow the opening of the door.
  • Such locks are moreover typically provided with a further safety device, which can be actuated by an external key, in order to lock the lever in the closed configuration, and thus prevent anyone who does not have the key from accessing the compartment.
  • the door should be closed while one or more persons are inside, for example for loading/unloading activities, or simply for maintenance, or for any other reason, they will then be in the position of not being able to get out, leading to distress and imposing a prolonged wait in the compartment, while waiting for help.
  • the aim of the present invention is to solve the above mentioned problems, by providing a lock, designed for the closing of a door to an inner compartment of a vehicle, that allows anyone working inside the compartment to exit, even in the event of accidental closure of the door.
  • an object of the invention is to provide a lock that can be actuated in a practical and easy manner, without requiring an excessive effort of the person who wishes to use it from inside the compartment.
  • Another object of the invention is to provide a lock the integrity of which is ensured, without therefore risk of being damaged, even following an excessive stress being imposed on the actuation mechanism (with the lock arranged in the closed configuration).
  • Another object of the invention is to provide a lock that ensures a high reliability of operation.
  • a further object of the present invention is to provide a lock that can be easily implemented using elements and materials that are readily available on the market.
  • Another object of the invention is to provide a lock that is low cost and safely applied.
  • a lock particularly for doors of vehicles of the type of vans, trucks, semi-trailer trucks and the like, comprising a box-like shell that can be fixed to either a door of a vehicle or the body of the said vehicle, a handle being pivoted to said shell for commanding a body that can slide from a closed configuration, in which a spring latch, supported by said body at an end region thereof, is engaged in an opening associated with the other one of the body of the vehicle and the door, in order to close the said door, to an open configuration, in which said spring latch is disengaged from the opening, in order to open the door and consequently gain access to the compartment inside the vehicle, and vice versa, characterized in that it comprises an emergency command element, which can be functionally associated with said spring latch and is operable from the side opposite to that of said handle with respect to said shell, said element being capable of being actuated on command, from the compartment inside the vehicle, for the movement of said spring latch and the passage from said closed configuration to said open configuration.
  • a lock according to the invention is particularly suitable for application to doors of vehicles of the type of vans, trucks, semi-trailer trucks and the like, and it is to such application that all reference will be made hereinafter.
  • the lock 1 comprises a box-like shell 2 that can be fixed to either a door of a vehicle or the body of the same vehicle, for example by way of screws or the like, which can be inserted in slots 3 provided in lateral shaped tabs 4 of the shell 2.
  • a handle 5 is pivoted to the shell 2 for commanding a body 6 that can slide (typically, in a direction parallel to the ground and to the door of the vehicle) from a closed configuration, in which a spring latch 7, supported by the body 6 at an end region thereof, is engaged in an opening associated with the other one of the body of the vehicle and the door, in order to close the door, to an open configuration, in which the spring latch 7 is disengaged from the opening, in order to open the door for the purpose of permitting, as a consequence, access to the compartment inside the vehicle, and vice versa.
  • the spring latch 7 is normally kept in the closed configuration thanks to the elastic reaction of a compression spring 8, wound, at least partially, about the body 6.
  • a compression spring 8 wound, at least partially, about the body 6.
  • the lock 1 is installed directly on the door, with the spring latch 7 capable of being engaged in an opening fixed to the body, but it is evident that the choice to install the lock 1 on the fixed body of the vehicle, while mounting the opening on the door, is absolutely equivalent and remains within the scope of protection claimed herein.
  • the lock 1 comprises an emergency command element 10, which can be functionally associated with the spring latch 7 and which operates (according to various methods) on the side opposite to that of the handle 5 with respect to the shell 2.
  • the element 10 can thus be actuated on command, from inside the vehicle, in order to allow a person who finds himself or herself (voluntarily or otherwise) inside the compartment, to move the spring latch 7 for the passage from the closed configuration to the open configuration (and thus enabling him or her to get out of the compartment).
  • the command element 10 is substantially constituted by a crank, which comprises a shaft 11 that rotates about its own axis and which extends from the shell 2 along a direction substantially perpendicular to the direction of sliding of the body (and thus along a direction substantially perpendicular to the plane defined by the door), from the side opposite to that of the handle 5.
  • a rod 13 Transversely fixed to the tip of the shaft 11 (which protrudes into the compartment through an opening provided in either the door or the body) is a rod 13, which can be gripped by a person in order to command the rotation of the crank (constituted by the rod 13 and by the shaft 11) and the consequent sliding of the body 6 from the closed configuration to the open configuration (when the crank is made to rotate in the direction indicated by the arrow in Figures 5 and 6 ).
  • the movement means 12 comprise a first rotating cam 14, keyed on the shaft 11 at the base of the latter and elastically kept away from a shoulder 15 defined along the body 6, when the latter is in the closed configuration.
  • the first cam 14 With its rotation (integrally with that of the crank), the first cam 14 is brought into abutment against the shoulder 15, to the point where it is pushed in order to thus obtain the movement of the body 6 which performs a translational movement until it causes, consequently, the passage from the closed configuration to the open configuration.
  • the lock 1 comprises an angular torsion spring 16, wound around the base of the shaft 11. It is thus the elastic reaction of the angular torsion spring 16 that keeps the first cam 14 away from the shoulder 15, in the closed configuration.
  • the command element 10 comprises a stem 17 that extends from the shell 2 along a direction substantially perpendicular to the direction of sliding of the body 6 (and to the plane that contains the door), from the side opposite to that of the handle 5.
  • the stem 17 is rigidly fixed to the body 6 at its base and preferably is provided with a knob 18 at its tip, which protrudes into the compartment through an opening provided in either the door or the body (and more precisely in whichever of the door and the body that the lock 1 according to the invention is installed on).
  • the tip of the stem 17 extends into the compartment and thus a person who also happens to be in the compartment (accidentally for example), can get out of it by entraining the stem 17, thus making it perform a translational motion along a direction parallel to the direction of sliding, thus causing at the same time the sliding of the body 6 and the disengagement of the spring latch 7 from the opening, in order to achieve the passage from the closed configuration to the open configuration.
  • the stem 17 in order to stably couple the stem 17 to the body 6, the latter is provided with an internally threaded recess 19, provided along its lateral surface, in order to accommodate a base portion, externally threaded, of the stem 17 (as can clearly be seen from Figure 8 ).
  • the command element 10 comprises an upright 20 that extends from the shell 2 along a direction substantially perpendicular to the direction of sliding of the body 6 (and to the door), from the side opposite to that of the handle 5.
  • the upright 20 is rigidly fixed to the body 6 at its base and is associated, at its tip (which protrudes into the compartment through an opening provided in either the door or the body, whichever the lock 1 is installed on) with a lever device 21.
  • the lever device 21 (which thus is substantially accommodated in the compartment of the vehicle, or at least facing thereto) can be actuated on command (by a person inside the vehicle) in order to bring a translational motion to bear on the upright 20 (possibly using a contained stress, thanks to the device 21 itself) and thus cause the consequent sliding of the body 6, for the passage from the closed configuration to the open configuration (and permit the exit from the compartment).
  • the device 21 comprises a lever pivoted to a fulcrum 22, which is fixed to the shell 2 and extends parallel to the stem 20.
  • a lever pivoted to a fulcrum 22 which is fixed to the shell 2 and extends parallel to the stem 20.
  • Such lever is substantially constituted by a contoured bar 23 that is pivoted to the fulcrum 22 at an intermediate portion thereof (as can clearly be seen from Figure 9 ).
  • the bar 23 defines, with an end portion thereof (folded into a U-shape), a grip 24 that can be gripped by a person and, at the other end with respect to the fulcrum 22, an end appendage 25 provided with a contoured slot 26 for guiding a portion of tip of the upright 20.
  • the latter in order to ensure the stable coupling between the upright 20 and the body 6, the latter (in the embodiment proposed in Figures 9 and 10 ) is provided with a pit 27, internally threaded, provided along its lateral surface, designed to accommodate a base portion, externally threaded, of the upright 20.
  • the command element 10 is substantially constituted by an elongated peg 28, the base of which is substantially wedge-shaped in order to abut against a corresponding inclined surface 29 provided along a flank of the body 6 on the opposite side with respect to the handle 5 (so as to be facing the compartment).
  • the peg 28 could be coupled to the shell 2, just as the construction is not ruled out of locks 1 according to the invention in which the peg 28 is decoupled from the body 6, and for example can be hung inside the door beside the shell 2.
  • the command element 10 comprises a traction wire 30, accommodated with a first portion thereof, fixed to the spring latch 7, in an internal duct of the body 6.
  • Such person can thus exert a tractive force on the wire 30 in order to cause the sliding of the body 6 and of the spring latch 7 with consequent passage from the closed configuration to the open configuration, thus ensuring the opportunity to get out of the compartment.
  • the slideable body 6 independently of the type of command element 10 chosen, the slideable body 6 comprises a first halfbody 6a and a second halfbody 6b (as can be seen in particular from Figures 5 and 6 ).
  • the first halfbody 6a is placed in contact with an end part of the command handle 5, and, more precisely, in this embodiment the end part coincides with the end protrusion 5a that exerts its thrust on the lip 9, which extends from the halfbody 6a.
  • the second halfbody 6b supports the spring latch 7, on the opposite side with respect to the first halfbody 6a.
  • the two halfbodies 6a, 6b are arranged aligned along the direction of sliding and are affected by mutual fastening means 31 operable by key.
  • the two halfbodies 6a, 6b can slide integrally (pushed by the end protrusion 5a of the handle 5 or, in the other direction, by the compression spring 8), while when the mutual fastening means 31 are deactivated, the second halfbody 6b is disengaged from the first halfbody 6a, and from the handle 5.
  • the spring latch 7 is kept locked in the closed configuration (inserted in the opening) even following actuation of the handle 5 (which, with the mutual fastening means deactivated, causes the sliding of the first halfbody 6a only), and this guards against the danger that a stress imposed on the handle 5 could cause damage to the various components of the lock 1 (or the opening thereof), which on the contrary is kept intact.
  • the mutual fastening means 31 comprise a thinned end tenon 32, which extends from the first halfbody 6a and which can be accommodated, on the opposite side with respect to the spring latch 7, in a central mortise 33 provided on the second halfbody 6b and which is delimited by two end arms.
  • the tenon 32 is further provided with a central hole 32a which is aligned, when the tenon 32 is accommodated in the mortise 33 (i.e. in the arrangement shown in Figures 5 and 6 ), with at least one counterhole 34 provided along at least one of the end arms.
  • the mutual fastening means 31 thus comprise a dowel 35 that can be moved, perpendicularly to the direction of sliding of the body 6, from a first limit position, in which the dowel 35 is inserted in the hole 32a and in the counterhole 34, in order to obtain the mutual fastening of the halfbodies 6a, 6b, to a second limit position, in which the dowel 35 is inserted in the hole 32a but not inserted in the counterhole 34, for the disengagement of the second halfbody 6b from the first halfbody 6a and thus from the handle 5.
  • a respective counterhole 34 is provided in each arm, and the dowel 35 can thus be accommodated, when it is in the first limit position, both in the first counterhole 34 and in the second, or in both.
  • the fastening means 31 comprise a second rotating cam 36, operable by way of the key.
  • the second cam 36 abuts against a pair of plates 37 fixed to the ends of a stem 38 that can move perpendicularly to the direction of sliding of the body 6, in a through slot 39 provided along the second halfbody 6b.
  • the dowel 35 is fixed to one of the plates 37, in such a way that when the second cam 36 is made to rotate (by the key, insertable in an opening 40), the shifting of the plates 37 causes the simultaneous translational motion of the dowel 35 which, while remaining within the hole 32a, can alternatively be inserted into and withdrawn from at least one of the counterholes 34, for the passage from the first limit position to the second limit position, and vice versa.
  • the mutual fastening means 31 can be deactivated (using a key) in order to mutually disengage the first halfbody 6a from the second halfbody 6b.
  • any force brought to bear on the handle 5 causes the shifting of the first halfbody 6a only, while the spring latch 7 (supported by the second halfbody 6b) is kept accommodated in the corresponding opening.
  • a person who should find him or herself inside the vehicle (and thus in a situation where it is impossible to actuate the handle 5, located outside) can move the body 6, and more precisely make it pass from the closed configuration to the open configuration, by acting on the command element 10.
  • the person can easily cause the sliding of the body 6 in order to withdraw the spring latch 7 from the opening, and thus have the opportunity to get out of the compartment, even following the involuntary closing of the door.
  • the lock according to the invention fully achieves the intended aim, in that the choice to provide the lock with an emergency command element, which can be functionally associated with the spring latch engageable in the opening, and which is operable from the side opposite to that of the handle that can be actuated in order to open the door, makes it possible to actuate the element, and consequently to move the spring latch, thus opening the door, from inside the vehicle, in so doing permitting the exit of anyone working inside the compartment, even in the event of accidental closure of the door.
  • an emergency command element which can be functionally associated with the spring latch engageable in the opening, and which is operable from the side opposite to that of the handle that can be actuated in order to open the door
  • the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.
