Technical Field

The present invention relates to tamper-resistant luggage, and more particularly to luggage having a zipper opening and tamper-resistant security features.

Background

It is well known that the luggage industry comprises a complex field in which widely varying requirements coexist. Fashion and technology are often difficult requirements to reconcile. Indeed, the combination of a satisfactory aesthetic aspect with a solution with added technical value (also known as "push-tech") is currently pursued in various types of bags, from the most elegant shoulder, shoulder or hand bags, to the more mobile backpack, purse bag, bucket bag and travel bag (duffle bag), to the more professional satchels, trolley cases, suitcases, briefcases, etc.

It has therefore been shown that the use of this technique plays a crucial role not only in promoting the so-called "exclamatory effect" of the case, but also in developing solutions particularly suitable for protecting the objects to be closed, for example by using high-performance materials, which give the case extremely high impact resistance, water-permeability, cut resistance and tear resistance, while ensuring water-, fire-and dust-protection.

It must be noted, however, that these advantageous technical aspects do not always fit and match well the aesthetic requirements of more traditional bags. For example, elegant and/or everyday luggage often has closure elements such as snaps, clasps, automatic buttons, rivets, clips, small straps, small laces, zippers, which are not suitable for ensuring the need for a secure closure (strong and effective under the effect of a strong penetration).

In particular, among these closure elements, the zip fastener is the most suitable solution for connecting two opposite flaps in a quick and sealed manner, which does not allow the passage of any solid or liquid, and at the same time presents a considerable aesthetic appearance, with a high versatility and acceptance of the slider and the teeth of the zip fastener. However, the zipper itself does not guarantee significant security against unauthorized opening.

Some solutions in the prior art are available, wherein security elements and systems applied to luggage are still provided. For example, WO201914504 discloses a luggage that includes a rigid inner skeleton, an outer liner disposed on top of the rigid inner skeleton, a locking assembly coupled with the inner skeleton, a biometric sensor, and a microcontroller. The locking assembly prevents access to the interior space when the locking assembly is in the locked state. The locking assembly includes a handle and an actuator. An actuator is disposed within the locking assembly to allow the locking assembly to be selectively switched from the locked state to the unlocked state. The microcontroller is programmed to determine whether the input provided to the biometric sensor corresponds to an authorized user, and in the affirmative, trigger the actuator to allow the locking assembly to reach the unlocked state, and in the negative, disallow the locking assembly from reaching the unlocked state. A user identification system is also provided in WO2017118919, which shows a closure device applied to a suitcase.

However, in the solutions of the known art, although specific structural configurations (for example, guarded structures) and efficient electromechanical access systems to the internal compartment associated with biometric readers are utilized to identify authorized users, they rely on bulky and less attractive locking systems and impose project restrictions on the aesthetics of the bag, and therefore they do not generally provide for the use of zippers.

In contrast, for cases or suitcases that employ zippers, in order to obtain a tamper-resistant feature, it resorts to a zipper locking device disposed outside the containment box; the locking means are then usually used to externally connect the pull tab (or zipper tabs) or the bridge of two respective opposing sliders, or to connect the pull tab or slider bridge to a stop member secured to the travel stop of the zipper. A typical example of this technique is disclosed in FR 3008285. It will be readily appreciated that such locking means, being mounted in the immediate vicinity of the zip fastener, are more susceptible to tampering and atmospheric agents, which inevitably reduce its useful life.

Furthermore, the fastening arrangement of the locking device inevitably provides an attachment and hooking point for tools intended for tampering, thereby facilitating leverage and having a higher chance of success in achieving destruction.

A different solution is shown in US2009/226050, where the slider lock is hidden. In this context, a slider locking mechanism of a slide fastener is disclosed, which acts from the inside by means of a pivoting fastening lever arrangement actuated by a solenoid valve. However, this mechanism has a certain volume in the direction of the movement axis of the slider. Furthermore, actuating elements are provided which have a degree of freedom in the zipper closing/opening direction, which are more susceptible to forces acting directly on the slider.

WO2018197170 shows a similar configuration.

Finally, WO2018186257 shows another safety locking arrangement for a slide fastener, in which the locking elements are moved in a direction transverse to the longitudinal axis of the slide fastener. However, this arrangement requires the creation of a special slide and also the design of a complicated and bulky actuating device.

Furthermore, it must be noted that, in addition to the prying action applied to the padlock or slider, with a conventional zipper (although the fabric of the edge is a cut and/or penetration resistant material, or although the connection of the edge to the fabric of the case is strong), it still reduces the resistance to precisely oriented penetration attacks between the gaps formed during coupling of the zipper teeth. In particular, by applying a pressure action between the zipper teeth with an awl, a force component can be obtained which separates the zipper teeth from each other and thus determines an unauthorized opening of the zipper.

It is therefore desirable to provide a case which is capable of protecting its contents by a robust construction and a security locking system applied to the zipper, arranged to close the interior cavity of the case, and housed so as not to be exposed to atmospheric agents and tampering, and further avoiding a configuration susceptible to forces in the longitudinal direction of the zipper. Finally, it is desirable to provide a construction that also resists penetration by the awl.

Disclosure of Invention

The object of the present invention is therefore to solve the drawbacks of the prior art, providing a case structure that allows to obtain an advantageous combination between aesthetic and anti-theft technical properties in the case of closures provided with zippers.

This object is achieved by a luggage having the features defined in claim 1. Further preferred features of the invention are defined in the dependent claims.

Detailed Description

In the context of this application, the term "bag" is understood to be a portable container that can be transported by hand, with shoulder straps or wheeled for keeping and carrying personal items, including valuables.

Luggage of this type generally consists of a closed container with aesthetic, soft or semi-rigid walls on the outside that define a closable opening. The last one provides at least two opposite edges, hinged or flexibly connected to the remaining walls of the case, these edges being equipped with two opposite parts of a zipper by means of which they can be stably held one next to the other to close the opening of the case.

In a manner known per se, the zip fastener consists of two opposite rows of metal teeth (or other suitable material) susceptible of being snap-engaged with the aid of a suitably shaped slider configured to slide constrained along the teeth. The two sets of opposite teeth are constrained on the edges of respective opposite strips L, which constitute the two components of the hinge and are fastened (by spreading or gluing) on the opening edge of the case.

FIG. 1 shows an exemplary luggage A provided with a zipper C arranged to close an opening providing access to one or more interior compartments. The zipper C comprises, in a manner known per se, a slider body Cu, which is equipped above it with a bridge P for connection to a pull tab (not shown).

According to a first embodiment of the invention, the slider body Cu is provided underneath with an arch E equipped with an engagement hole Ei. Preferably, the coupling eyelet Ei is in the shape of a cylindrical hole, the axis of which is orthogonal to the longitudinal plane of the slider body Cu, i.e. to the plane in which the slider Cu is slidingly guided in the opening/closing movement of the slide fastener.

In correspondence with the end of travel stop of the slider Cu along the zipper C (i.e. the end of travel determining the closure of the zipper C), the case a has a terminal side on which locking means 1 are provided, which are housed completely below the plane of the zipper C (i.e. inside the case a).

As shown in fig. 2 and 3, the locking device 1 includes a catch clip 2, a detent mechanism 3 and an appropriately controlled actuator 4.

The locking device 1 is housed in a compartment provided inside the case a, for example integrally fixed to an inner skeleton (rigid, for example made of resin or sheet metal, or flexible) suitably provided in the layer constituting the wall of the case a.

The clip 2 consists of a transmission arm 2a (preferably a flat bar of metal material), which transmission arm 2a is constrained to a driving rod 4a of the actuator 4, the driving rod 4a being arranged to perform an alternating translational movement. The translational movement of the clip is orthogonal to the longitudinal axis of the zipper, along which the slider Cu slides: this determines the inherent robustness of the system to attempts to break the lock.

The transmission arm 2a is further provided with a locking pin 2d, the axis of the locking pin 2d being parallel to the direction of the alternating movement of the driving rod 4 a. The locking pin 2d is shaped and in section suitable to fit into the hole of the eyelet Ei of the arch E; the free end 2e of the locking pin 2d is preferably rounded, for example semicircular, to facilitate its operation, as will be explained below.

Since the locking pin 2d is intended to engage the eyelet Ei, the relative position between the locking device 1 and the sliding plane of the slider Cu is defined so that when the slider Cu is at the end of its stroke, the locking pin 2d finds itself on the translation axis aligned with the position of the eyelet Ei.

The driving arm 2 is controlled in its alternating translational movement by an actuator 4. The actuator may be manually controlled, but it is preferably an electromechanical actuator 4.

The actuator 4 according to the illustrated embodiment is of the solenoid type, comprising a ferromagnetic armature and a coil, through which an electric current is passed to generate a translational movement of a ferromagnetic control rod 4a, which is slidably mounted on the central axis of the coil.

The system also provides an electrical energy accumulator (e.g. a battery) mounted within the housing of the locking device 1 or at a remote location (e.g. below the bottom of the case).

The electromagnetic actuator 4 may be configured for active movement of the rod 4a in two directions; preferably, however, for the sake of structural simplicity of the actuator 4 and the control thereof, the active actuation is provided to take place in one direction only, while in the opposite direction the movement is ensured by an elastic element provided to the positioning mechanism 3, as will be seen later.

The operation of the actuator 4 is controlled by a trigger unit on which a user can act to determine the opening of the bag a. The triggering unit is arranged in the vicinity of the locking device 1, but at least a part of it (on which the user must act) is configured to be able to protrude through the wall thickness towards the outside of the bag a, typically corresponding to the side of the bag a adjacent to the travel stop of the slider Cu.

In the case of the electromechanical actuator 4, a suitable electrical circuit is provided by means of which the electromechanical actuator 4 is connected to a source of electrical energy (for example an accumulator located on the bag a).

The triggering unit is for example in the form of a biometric recognition device 5. Preferably, the biometric identification means 5 is a fingerprint reading and authentication means.

Alternatively or additionally, the triggering unit comprises a mechanical assembly 6, the mechanical assembly 6 enabling the user to activate the actuator 4, for example acting directly on the driving rod 4a or on a manual switch (for example a push-button switch) which establishes an electrical connection between the solenoid of the actuator 4 and the source of electrical energy.

The combining means 6 comprise, in a manner known per se, a mechanical system which releases the switch each time the correct number or alphanumeric combination is entered on a plurality of manipulable selectors, for example small wheels with numbering. The combined device 6 may replace the biometric device or it may be used in place of the biometric device 5 when there is an electronic failure or the supply battery is completely depleted or when the electronic components are in an off-line mode.

The sensor of the at least one biometric identification means 5 and/or the selector of the combining means 6 protrudes outside the bag a.

According to a preferred embodiment, the actuator 4 is of the single-effect type, so that it controls the translation of the transmission arm 2a in a single direction.

In this case, a positioning device 3 is provided, which defines stable and unstable positions of the actuator arm 2. For example, the positioning device 3 has a hollow cylindrical body 3a, and a gear plunger 3b and a return spring 3c that move integrally with the transmission arm 2a are housed in the body 3 a. The positioning device 3 operates to extend or retract the nib in a manner similar to a snap-fit mechanism used in ballpoint pens.

In particular, due to the configuration of the gear plunger 3b and the containing wall of the hollow body 3a, the axial displacement of the plunger 3b in opposition to the return spring 3c results in two different stable conditions. The first stable condition is the condition shown in fig. 5A, in which the plunger 3b is in the initial position, the return spring 3c is compressed and thus elastically loaded: in this position, the transmission arm 2a is arranged so that the locking pin 2d remains in the trajectory followed by the arch E, except for the rounded end portion 2E. The second stable condition is the condition shown in fig. 5B, in which the plunger 3B is in the fully withdrawn position, and the return spring 3c is extended and unloaded. In the following, the operation of the locking device 1 according to the invention is briefly described.

In the first step, starting from the state in which the zipper C is opened, the positioning means 3 is in the initial position. As clearly seen in fig. 5A, the driving arm 2a keeps the locking pin 2d spaced apart from the track of the slider Cu located above, except for the head 2 e. When the slider Cu pushed by the user moves to its end-of-travel position to close the zipper C, the arch E abuts the circular head 2E, thus pushing the locking pin 2d (and thus the actuator arm 2a) to move further backwards (arrow R). Due to this backward movement, the return spring 3c is further compressed and the positioning mechanism loses its stable condition.

At this time, the elastic load accumulated in the return spring 3c is released and biases the lock pin 2d forward (in the direction opposite to the arrow R) with a significant force. At the end of the travel of the slider Cu, the pin 2d is flush with the hole Ei of the arch E, so that the locking pin 2d is strongly biased into the hole Ei (fig. 5B). Note that the insertion of the locking pin 2d occurs in a direction orthogonal to the opening and closing direction of the slider Cu along the longitudinal axis of the slide fastener.

A new stable condition is thus reached, in which the locking pin 2d engages the hole Ei of the arch E: the slider Cu therefore remains captured by the locking device 1 and is no longer allowed to slide along the zipper C, thus determining a safe closure.

Thus, the condition of the slider Cu locking closed is obtained by the automatic snapping of the elastic mechanism: no further active intervention by the user is required.

When it is desired to continue to release the slider Cu, in order to be able to open the zip fastener C, the user must act on the triggering unit to cause the actuator 4 to return the driving arm 2 again (arrow R), so as to extract the locking pin 2d from the eyelet Ei (fig. 5C). To do this, the user acts on the biometric device 5 or another equivalent mechanism to toggle the switch and supply power to the solenoid of the actuator 4.

It will be appreciated that the biometric identification device 5 is kept in the on mode by the supply of power from the storage battery in the bag. If reading the fingerprint results in a positive result of a valid authorization, the biometric identification means 5 causes the actuator 4 to actuate.

The actuator 4, powered by the accumulator, itself pushes the plunger 3b completely into the cylindrical body 3a, causing a new elastic load of the return spring 3c (the return spring 3c is therefore suitable for the subsequent closing cycle): the slider Cu is disengaged from the pin 2d and can freely slide along the slide fastener C. Once the action of the actuator 4 is released, the plunger 3b is pushed slightly outwards by the bias of the return spring 3c until it returns to the first stable position shown in fig. 5A.

In summary, as soon as an authorized user acts on the trigger unit, it can be pulled by the pull tab (slider Cu) away from the engagement position with the security device 1, thereby opening the zipper C. When the user disengages the trigger unit, for example, removes the finger from the biometric reading position, the actuator 4 is deactivated, which suspends the electromagnetic force exerted on the moving rod 4 a. At this point, once the pushing force is over, the return spring 3c begins to extend, returning the positioning device to the stable state shown in fig. 5A.

As previously mentioned, the full mechanical arrangement of the combination means 6 may be utilized as an alternative to using the solenoid actuator 4 in combination with the biometric identification means 5.

Furthermore, the biometric identification device 5 and the combination device 6 may be provided physically separate and remote from the security device assembly 1, wherein the biometric identification device 5 is electrically connected to the actuator 4 by a suitable length of electrical wiring, and the combination device 6 is mechanically connected to the actuator arm 2a of the anchoring system 2 by a suitable system of suitable length of rod or by another mechanical means. All this is to prevent tampering which might successfully remove the biometric identification device 5 and/or the combination device 6 from its housing. Thus, placing the security device 1 in a compartment embedded between the fabric layers may ensure further protection of the security device 1, which is also difficult to reach through the housing of the biometric identification device 5 and the combination device 6 either manually or by prying means once the housing of the biometric identification device 5 and the combination device 6 has been deliberately removed for criminal purposes.

Fig. 6 shows a practical embodiment of the lock according to the invention, in which the various components are housed in a containing body to be embedded in the wall of the suitcase.

In accordance with another aspect of the invention, to add to the security features of case A, a special structure of zipper C is provided, which makes it more resistant to improper opening attempts.

In particular, as shown in figure 7A, two layers 7, 8 of semi-rigid material (e.g. polymeric material) are provided below the two parts of the zipper C (i.e. on the inside of the case a).

The two layers 7, 8 projecting from the two opposing parts of the zipper extend transversely to the zipper longitudinal axis by at least 10mm and partially overlap each other by a width of 2-15 mm.

Preferably, said layers 7, 8 are sewn lips, for example by sewing with nylon thread reinforced with polymer-based fibres, on the supporting strips L of the two rows of engaging teeth D of the zip fastener.

As shown in fig. 6, the two opposing layers 7, 8 are mounted to partially overlap corresponding to the longitudinal axis of the slider Cu. The two layers 7 and 8 may be partially bent inwards under the push of the arch E when the slider Cu passes.

It has been determined through experimental testing that for a range of different materials (see fig. 7B and 7C), such as polymers, polymer fabrics, metals, cardboard or other materials, the effectiveness of both layers can be maintained as long as the properties of the material and the thickness of the board ensure self-support of the layer that is joined to the zipper part in a cantilever fashion. By self-supporting it is meant that the layer is cantilevered from the attachment line to the support strip L along its entire length transverse to the zipper, maintaining itself substantially in a plane and without natural bending (as would occur if very soft materials were used). This feature keeps the layers 7 and 8 in contact with each other and against the arrangement of teeth D when the zipper is closed.

This very simple solution proves to be very effective against theft attempts, while increasing the rigidity of the bending deformability of the zip fastener C. In particular, this solution prevents to a greater extent the penetration action of the cusp load exerted in the gaps between the coupled teeth, dispersing and suppressing the energy of such a stress action applied to the slide fastener C.

According to another aspect of the invention, the structure defining the container or shell of the bag a has a complex layered configuration.

In particular, the walls of the enclosure are defined by the overlap of layers of different materials, except for the portions of the rigid inner skeleton that readily accommodate the security device 1 (e.g. located at the sides of the bag a), as shown in figure 7.

The outermost layer 9 is of leather (for example, cow leather having a thickness in the range between 0.8 and 1.8 mm) which, in addition to being waterproof and abrasion resistant, has also proved suitable for achieving the desired aesthetic finish.

Furthermore, a protective multilayer, in particular a sandwich-like arrangement, consisting of superposed layers of at least two different materials is employed further on the inside, comprising a layer 10 resistant to shear forces (for example Cut-Pro material) which layer 10 is interposed between two layers 11 of fire-blocking material (e.g. manufactured by DuPont, Wilmington, Delaware, USA)Material). The innermost layer 12 is a protective facing liner.

This delamination thus allows to obtain a housing resistant to shear and penetration and constitutes an effective, flame-retardant thermal insulation. Finally, the liner is composed of a conventional fabric suitable for aesthetic applications, such as polyester or synthetic fibers of polyester blended with cotton. Other materials, such as layers of aramid synthetic fibers or other technical materials, are not excluded.

Preferably, on the bottom of the case a there is provided a protective casing, provided in a suitable compartment inside the case a, containing the power supply unit for the device 1. The power supply unit (not shown) comprises, for example, a lithium-Ion (Li-Ion) battery or a lithium-polymer battery (Li-Po) and a main electronic board comprising a microcontroller or a general-purpose electronic processor, suitable for managing the peripheral electromechanical components on the device 1, such as the biometric identification device 5 and the actuator 4, and also managing the charging/discharging cycles of a power supply battery that can be connected to the charger, for example, through a mini USB socket or a similar general-purpose socket.

Among the electronic components that can be provided, at least the communication module is also preferably installed in an electronic board, for example of the GSM, 4G, 5G, WiFi, bluetooth type, and/or a geolocation module, for example of the GPS type.

At least a speaker (for example a buzzer) arranged inside or outside the suitcase a is also provided, if necessary, intended to emit an acoustic alarm signal as soon as an appropriate motion sensor detects the presence of an unauthorised intrusion in the compartment of the suitcase a.

Furthermore, in the case a tracking system (known per se) is provided, which communicates with the outside through a receiving-transmitting circuit, which may make use of various data transmission modules, some of which have been mentioned previously, in order to track the case a and to transmit the relative position to a dedicated server. Therefore, under the condition of being stolen, the position of the case A can be known in real time, so that the case A can be found out more easily.

Furthermore, the receiving-transmitting device is provided to one side of the bag a housed in the rigid container.

Furthermore, a motion sensor (e.g. a MEMS accelerometer) is provided which detects the motion state of the bag a in order to allow management of the various electronic devices in an energy saving mode.

From the above description it is clear that the case a according to the invention perfectly achieves the set aims.

Indeed, the case a described herein represents an effective solution to the need to be able to obtain a portable container which is generally equipped with suitable means effective to contribute to the safety of the goods stored inside, while being a product without excessive constraints from an aesthetic point of view, since it provides a safety zipper.

In particular, thanks to the presence of the safety device 1, the above problems are effectively solved, resulting in a strong, accurate, fast actuation of the slider Cu of the zip fastener C and a closure system that is simple to construct. Furthermore, the security device 1 is arranged within the compartment to avoid exposure to direct prying blows.

Furthermore, the reinforcement provided by the layer below the zipper C proves to be a suitable solution to resist the penetration behaviour on the zipper C, which is generally an easy and quick closing means, but is characterized by a reduced resistance to vertical shear stresses.

Also, by using superposed layers of different materials, each having its own execution function, a case a is defined which has high resistance to shearing, penetration and fire, and waterproof characteristics.

Finally, in the event of a theft, the bag a can be easily tracked by means of a tracking and geographical locating device, embedded in the reinforced fabric and protected by a sturdy container, stably fixed to the main structure of the bag a, to prevent vandals from destroying the intention of the bag a.

It is understood, however, that the invention is not to be considered as limited to the particular arrangements shown above, which constitute only exemplary embodiments thereof, but that different variants are possible, all within the reach of a person skilled in the art, without departing from the scope of protection of the invention, which is defined solely by the claims appended hereto.

For example, although reference has been made to an arch in the inner portion of the zipper slider, it should be understood that the shape need not be that of an arch, so long as it has an engagement eyelet.
