DESCRIPTION

TECHNICAL FIELD OF THE INVENTION

The present invention relates, in general, to the technical field of machines and/or equipment for duplicating keys. More particularly, the invention relates to an easily transportable key duplicating machine, usable for duplicating keys in mobility, which is equipped with an extractable power supply battery.

BACKGROUND OF THE INVENTION

As known, the key duplicating operation consists of reproducing on a blank key a set of grooves, notches, holes and/or punches, which distinguish the key to be duplicated, i.e. define the so- called “encryption” or “code” of the key itself.

Keys are normally duplicated by using special mechanical or electronic key duplicating machines.

A mechanical key duplicating machine typically comprises a pair of adjoining clamps to secure, respectively, an original key to be duplicated and a blank key, which must be shaped according to the original key to obtain a copy key.

A mechanical duplicating machine also comprises a mechanical probe, to detect the encryption of the original key to be duplicated, and a milling group with a milling tool, to replicate the detected encryption on the blank key. The clamps are mounted on a common support, which can be moved with respect to a machine frame along two or three mutually orthogonal directions, while the mechanical probe and the milling group are fixed or movable.

To carry out the duplication, an operator acts on the common support of the clamps to keep the original key to be duplicated into contact with the probe and to make the contact point slide along its entire encryption. The movement of the common support deriving from this “tracking” action is transferred to the blank key, which is thus simultaneously machined by the milling tool in a manner corresponding to the detected encryption.

An electronic key duplicating machine typically comprises, on the other hand, a single clamp to secure the key to be duplicated and the blank key, at successive times, a detection group, comprising, for example, an electromechanical or optical detector to detect the encryption of the key to be duplicated, and a milling group with a milling tool to reproduce the detected encryption on the blank key. The clamp and/or the detection and milling groups are mounted in a movable manner with respect to the machine frame, so that at least two, and sometimes even three, degrees of freedom are achieved. An electronic key duplicating machine further comprises an electronic control unit, through which it is possible to control the movement of the clamp and/or the detection and milling groups as well as their operation automatically.

To make a duplicate, an operator firstly secures the key to be duplicated in the clamp. Following an activation command, the electronic control unit activates the detection group and automatically moves the clamp or detection group so that it detects the encryption of the key to be duplicated. The signals generated by the detection group are received by the electronic control unit and processed and stored through a suitable software. When the detection is complete, the original key to be duplicated is replaced with the blank one. At this point, following an activation command, the electronic control unit activates the milling group, so that the previously detected and stored encryption is reproduced on the blank key. As an alternative to the duplication procedure described above, with the key duplicating machines of the electronic type, it is also possible to make copies starting from encryptions directly present or loadable in a memory of the electronic control unit, without the need to physically avail of the original key to be duplicated.

Keys are usually duplicated in specialized centres. However, there is sometimes a need to make duplicate keys in mobility to quickly and locally have a key whose encryption is known or can be determined.

To this end, there are on the market key duplicating apparatuses which are small in size and easily transportable.

An example of a mobile key duplicating apparatus is disclosed in the patent application W02020/0170118. This duplicating apparatus comprises a key duplicating machine, which is removably housed in a transport container, preferably of the shoulder type or transportable as a trolley. The transport container comprises a support base for removably fixing the key duplicating machine and at least one portion which can be opened to access the key duplicating machine housed inside it.

The duplicating apparatus can also be provided with a portable rechargeable power supply battery and for this purpose the transport container comprises an external pocket for housing this battery. The external pocket is preferably provided with a closing flap, which can be opened and closed by means of a zip, and is in communication with the interior of the transport container by means of an opening, which can be used for the passage of a power cable of the rechargeable portable battery, which extends between the battery and the key duplicating machine housed in the transport container.

The fact of providing a portable power supply battery, therefore external to the duplicating machine, however involves a series of drawbacks.

Firstly, the external power supply battery could be inadvertently disconnected from the duplicating machine, especially when the latter is working for key duplication. This causes an interruption of the duplication process, following to which the user could be forced to replace the partially duplicated blank key with a new blank key, with an obvious waste of material and lengthening of duplication times. Moreover, if the external power supply battery should run out when the duplicating machine is in use, in the absence of the possibility of connection to the mains, the user would no longer be able to operate.

Secondly, the presence of an external battery increases the overall dimensions of the duplicating machine, which could be disadvantageous if the space available to the operator of the duplicating machine is limited or reduced.

Furthermore, the operator of the duplicating machine could forget to take the battery and/or the cable connecting the battery to the duplicating machine with him, when he goes to the place of duplication, with the consequent impossibility of starting up the duplicating machine in the event it was not possible to connect the machine to the mains.

Mobile key duplicating apparatuses according to the prior art are also described in the patent documents KR 200 309 438 Yl, KR 100 455 827 Bl, EP 3 689 520 Al and IT 2018 00005296 Al.

SUMMARY OF THE INVENTION

The main object of the present invention is to provide a machine for duplicating keys in mobility, configured so as to solve in a simple and effective way the drawbacks described above with respect to known portable key duplicating machines.

More particularly, the main object of the present invention is to provide a machine for duplicating keys in mobility, configured so as to guarantee the correct operation of the same machine, in particular avoiding its accidental switching off during operation.

Another object of the present invention is to provide a machine for duplicating keys in mobility, configured so as to be easily used even in conditions of reduced or limited space.

Still another object of the present invention is to provide a machine for duplicating keys in mobility, configured so as to allow rapid insertion of a power supply battery.

These and other objects, which will become more apparent in the following description, are achieved by a machine for duplicating keys in mobility having the characteristics set forth in the attached independent claim 1. Preferred characteristics of the machine for duplicating keys in mobility are the subject of the dependent claims.

The invention therefore relates to a machine for duplicating keys in mobility comprising a clamping group, which is configured to secure at least one key to be duplicated, a milling group, which is configured to reproduce the encryption of the key to be duplicated on a blank key, and a frame for supporting the clamping group and the milling group. The duplicating machine further comprises a base and a support wall, which extends from the base and with respect to which a first portion and a second portion of the duplicating machine are defined, wherein the first portion delimits a work space, where the clamping group and the milling group are located. The duplicating machine is characterized in that a seat is formed in the second portion for the removable coupling of a power supply battery, whereby the power supply battery is inserted and extracted into and from the seat according to a predetermined direction and without the removal of components of the duplicating machine.

Thanks to this combination of features, and in particular thanks to the fact that the duplicating machine is equipped with a power supply battery that can be coupled in a removable way to the structure of the machine, the battery is prevented from disconnecting from the duplicating machine when it is in operation and at the same time that the user forgets to bring the battery to the place where the duplicating machine is to be used, with the consequent impossibility of using the machine itself, if it is not possible to connect it directly to the mains. Furthermore, the key duplicating machine thus conceived has a small size, and can therefore also be used in conditions in which the space available is reduced or limited. Furthermore, the fact of providing a removable power supply battery facilitates the replacement of the battery, once ran out, with a new charged power supply battery. Furthermore, since the battery can be inserted and removed in and from its seat without having to remove parts of the duplicating machine and/or without having to fix it to the frame and/or casing of the duplicating machine, for example by means of screws and/or bolts, the coupling and decoupling time between the duplicating machine and the power supply battery is greatly reduced.

In one embodiment, the duplicating machine comprises a protective casing, which includes a fixed part and a movable part, wherein the fixed part is located in the second portion of the duplicating machine and is supported by a part of the base, wherein the seat for the removable coupling of the power supply battery is defined in correspondence of the fixed part of the protective casing.

In one embodiment, the movable part of the protective casing of the duplicating machine is rotatable with respect to the fixed part to allow or prevent access to the work space where the clamping group and the milling group are located.

In one embodiment, the seat for the removable coupling of the power supply battery extends vertically and inside the second portion of the duplicating machine, whereby the power supply battery is inserted and extracted in and from the housing seat according to a direction which is orthogonal to a support plane for the duplicating machine. In alternative, the seat for the removable coupling of the power supply battery extends horizontally and inside the second portion of the duplicating machine, whereby the power supply battery is inserted and extracted in and from the housing seat according to a direction which is parallel to a support plane for the duplicating machine.

In one embodiment, the seat for the removable coupling of the power supply battery extends, vertically or horizontally, outside the duplicating machine, whereby the power supply battery is inserted and removed in and from the seat according to a direction which is orthogonal or parallel to a support plane for the duplicating machine.

In one embodiment, a pair of guides is formed in the seat for the removable coupling of the power supply battery, each of which is configured to cooperate with a respective longitudinal groove formed in the power supply battery to facilitate sliding insertion and extraction of the power supply battery in and from the seat.

In one embodiment, each guide extends from a proximal wall of the seat and comprises a pair of longitudinal plate-like elements, facing each other so as to define a space and each groove of the power supply battery is configured so as to define a longitudinal slot, configured to receive a respective longitudinal plate-like element of a guide of the pair of guides, and a rear portion of the power supply battery, configured to be slidably inserted and extracted in the space delimited between the pair of plate-like elements of each pair of guides.

In one embodiment, the longitudinal plate-like elements of each pair of longitudinal plate-like elements comprise a proximal longitudinal plate-like element and a distal longitudinal platelike element, which are bent in an L shape and juxtaposed so as to form as a whole a U inside which the space for sliding reception of the rear portion of the power supply battery is delimited. In one embodiment, the duplicating machine further comprises an electronic control unit, operatively connected to the clamping group and to the milling group and means for signalling the correct positioning of the power supply battery in the seat and/or the state of charge of the power supply battery.

In one embodiment, the signalling means comprises at least one LED and/or a graphical user interface and/or a mobile computer device on which a program or a software application is installed, wherein each signalling means is in electrical communication with the electronic control unit.

In one embodiment, the duplicating machine comprises a plug to which an adapter can be connected for the use of an external portable power supply battery.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

With reference to Figures 1 to 11, a machine for duplicating keys in mobility according to a preferred embodiment of the present invention is schematically illustrated.

As shown in detail in Figures 3 and 4, the duplicating machine, generally indicated by the reference numeral 100, includes a base 11 and a support wall 12, which vertically extends from the base 11. The duplicating machine 100 (hereinafter also indicated with the term machine 100) comprises a first portion Pl (hereinafter also indicated as front portion Pl) and a second portion P2 (hereinafter also indicated as rear portion P2), which are defined on opposite sides with respect to said support wall 12. In other words, the two portions Pl, P2 of the machine are defined on opposite sides with respect to the support wall 12. In Figures 5, 10, 12 and 13 it is drawn the plane PR on which the support wall 12 develops, where this plane PR shows how the two portions Pl, P2 of the machine 100 remain defined by the position of the support wall 12. The first portion Pl of the duplicating machine 100 comprises a first part 11-1 of the base 11 (or front part 11-1 of the base 11), while the second portion P2 comprises a second part 11-2 of the base 11 (or rear part 11-2 of the base 11). The two parts 11-1 and 11-2 of the base 11 are also opposite with respect to the support wall 12.

The first portion Pl of the machine 100 delimits a work space of the duplicating machine 100, where a clamping group 30, for secure keys to be duplicated whose encryption must be detected and/or blank keys to be machined correspondingly to a detected or known encryption, and a milling group 40, configured to work blank keys are placed. The second portion P2 of the machine 100 includes and/or supports the other components (for example control, power supply, actuation components) necessary for the functionality of the machine itself, which in any case do not come into contact with the key to be duplicated.

The support wall 12 supports the milling unit 40 (see Figures 3 and 4), while a front part 11-1 of the base 11 supports, completely or partially, the clamping group 30. If a function of encryption detection is provided, in the work space there will also be a respective detection group, for example of the optical or electromechanical type (not shown in the figures). The clamping group 30 comprises a clamp 31, which is mounted on a slide 32 which can be moved on a respective guide 33 fixed to the base 11 along a first direction parallel to the base 11 and perpendicular to the support wall 12.

The milling group 40 typically comprises a powered spindle onto which a milling tool is keyed. The milling group 40 is mounted on a first slide (not visible in Figures 3 and 4) which can be moved on a respective guide 41 along a second direction parallel to the support wall 12 and perpendicular to the first direction. The guide 41 is, in turn, mounted on a second slide 42, which can be moved on a respective pair of guides 43 along a third direction, parallel to the support wall 12 and perpendicular to the first and second directions.

Overall, therefore, the clamping group 30 and the milling group 40 form a working system with three degrees of freedom, very flexible and in particular suitable for duplicating flat keys, both laser or dimple keys.

As can be seen for example in Figure 1, the duplicating machine 100 comprises a protective casing 20 comprising a fixed part 21 and a movable part 22. The fixed part 21 of the casing 20 is placed in the rear portion P2 of the machine 100 and supported by the rear part 11-2 of the base 11. The movable part 22 is preferably designed as a pivotable cap, which can be raised or lowered, respectively, to allow or prevent access to the work space. Preferably, at least for the movable part 22, the protective casing 20 is transparent. In the figures, the movable part 22 is shown in the lowered position in which it delimits, together with the front part 11-1 of the base 11 and the support wall 12, the work space indicated above. When the movable part 22 occupies the raised position (not shown in the figures), the work space is made accessible to an operator. Preferably, the key duplicating machine 100 also comprises a handle 23, to facilitate its grip by a user during his movements, for example to insert or extract it from a transport container (not shown). By way of an example, the transport container is of the shoulder type and therefore comprises a pair of shoulder straps, which allow it to be transported as a backpack.

In accordance with the present invention, a seat 24 is formed in the rear portion P2 of the machine 100 for the removable coupling of a power supply battery 50. In particular, according to the invention, the power supply battery 50 can be inserted into and extracted from the seat 24 according to a predetermined direction, without removing components of the duplicating machine. In other words, the power supply battery 50 can be inserted from the outside of the machine directly into the seat 24 without the need to remove other parts of the machine, for example covering parts, internal parts, screws or other connection means. Similarly, advantageously, also the extraction/removal of the supply battery 50 from the seat 24 towards the outside is equally direct.

More precisely, in the embodiment of Figures 1 to 13 A, the seat 24 is defined at the fixed part 21 of the protective casing 20, on the opposite side with respect to the work space of the duplicating machine 100. This seat 24 extends vertically to the inside of the duplicating machine 100.

In particular, and as shown in detail in Figures 12 and 13A, the seat 24 comprises a proximal wall 24a, i.e. closest to the front portion Pl of the machine 100, a distal wall 24b, i.e. furthest from the front portion Pl of the machine 100, a pair of side walls 24c, connecting the proximal wall 24a and the distal wall 24b, and a bottom 24d.

The duplicating machine 100 also comprises a power supply battery 50, which is housed in the seat 24 in an extractable manner along a vertical direction, i.e. orthogonally to a support plane PO (indicated in Figures 5, 10 and 12) for the machine 100. The seat 24 can be configured in such a way that, following its insertion, the power supply battery 50 is completely housed inside the fixed part 21 of the protective casing 20. Alternatively, as can be seen for example in Figures 5 and 12, the seat 24 can be configured so that the battery 50, following its insertion in the seat itself, remains partially protruding from the fixed part 21 of the protective casing 20.

With reference again to Figures 9 to 13 A, a pair of guides 25 are formed inside the seat 24, to facilitate the insertion and extraction of the power supply battery 50 into and from the seat 24. In particular, each guide 25 of the pair of guides consists of two longitudinal plate-like elements, in particular, a proximal longitudinal plate-like element 26a, i.e. closest to the front portion Pl of the machine 100, and a distal longitudinal plate-like element 26b, i.e. furthest from the front portion Pl of the machine 100, which are preferably bent in an L shape and juxtaposed so as to form as a whole a U. Preferably, the guides 25 extend from the proximal wall 24a of the seat 24, towards the inside of the seat, preferably for the entire depth of the seat 24, and a space S (see Figure 9) is delimited between the longitudinal plate-like elements 26a and 26b of each guide 25.

In the battery 50 there is also formed a pair of rear longitudinal grooves 52, each of which is configured so as to define a longitudinal slot 52a, configured so as to receive a respective distal longitudinal element 26b of a guide 25 of the pair of guides, and a rear portion 53 of the battery 50, configured so that it can be slidably inserted and extracted in the space S delimited between the proximal longitudinal plate-like element 26a and the distal longitudinal plate-like element 26b of each pair of guides 25.

In the seat 24, preferably at its proximal wall 24a, electric contacts 54 for the power supply battery 50 (visible in Figure 12) are also formed.

Preferably, the duplicating machine 100 further comprises a portable power supply battery not shown), preferably of the rechargeable type, which is preferably housed in an external pocket of a transport container (not shown) of the duplicating machine 100. The electrical connection between the portable power supply battery and the duplicating machine 100 is made by means of a power supply cable, which is connected to a plug 26 (see for example Figure 5) provided in the duplicating machine 100, preferably at the base 11. An adapter (not shown) can also be connected to the plug 26, which allows a different portable power supply battery, for example a portable power supply battery of different amperage, to be used. Furthermore, a power supply cable of the duplicating machine 100, for connection to the mains, can be connected to the plug 26.

In one embodiment, and as shown in Figures 3 and 4, the duplicating machine 100 further comprises an electronic control unit or CPU (Central Processing Unit) 60, which is also placed in the work space of the duplicating machine 100 and to which the clamping group 30 and the milling group 40 are electrically connected.

The duplicating machine 100 also comprises means for signalling, to a user U, at least one operating condition of the extractable power supply battery 50, in particular means for signalling the correct positioning of the power supply battery 50 and/or the charge status of the power supply battery 50.

In one embodiment, these signalling means consist of one or more LEDs (Light Emitting Diode) 62, visible for example in Figure 1, preferably provided at the fixed portion 21 of the protective casing 20.

In alternative or in addition to the LEDs 62, the signalling means can consist of a graphical user interface, or GUI (Graphical User Interface) 64 - shown in Figures 3 and 4 - which is in electrical communication with the electronic control unit 60 and is configured to signal to the user U, for example by means of a visual or acoustic message, the state of charge of the power supply battery 50 and/or its correct positioning.

In alternative or in addition to the LEDs 62 and/or the GUI 64, the signalling means can consist of a computerized device, preferably a mobile computerized device, for example a smartphone 66.

The mobile computerized device 66 is configured to communicate with the duplicating machine 100, in particular with its electronic control unit 60 according to wireless communication modes. The mobile computerized device 66 and the key duplicating machine 100 are therefore preferably provided with communication ports (not shown) capable of locally implementing wireless communication protocols, such as for example WiFi™, Bluetooth™, Zigbee™ communication protocols, protocols for LANs (Local Area Networks) and the like.

Preferably, a software program is installed on the computerized device, or a software application 66A, in the case of the smartphone 66 shown in Figures 3 and 4, which is configured to interact with the duplicating machine 100, when carried out by the computerized device. The software program or software application allows the computerized device to exchange command data with the duplicating machine 100.

By way of example, to signal the state of correct insertion of the power supply battery 50 in the seat 24, the electronic control unit 60 is configured to detect the input voltage and if this voltage is equal to a predetermined value, equal to approximately 36 Volt, the signalling means 62, 64, 66 communicate to the user U that the power supply battery 50 has been correctly inserted in the seat 24. Otherwise, i.e. if the electronic control unit 60 detects a different value of the input voltage, the signalling means 62, 64, 66 communicate to the user U that the power supply battery 50 is not in its correct position and that it is therefore necessary to reposition it in the seat 24. Naturally, it is possible to provide any other alternative mode of signalling the state of correct positioning of the power supply battery, within the reach of a person skilled in the art. Always as an example, to signal the state of charge of the power supply battery 50, the electronic control unit 60 counts the number of keys duplicated by the duplicating machine 100 and when this number reaches a predetermined threshold value, for example equal to about 20 keys, the signalling means 62, 64, 66 communicate to the user U that the power supply battery 50 is about to run down and it is therefore necessary to replace it. Of course, it is possible to provide any other alternative mode of signalling the state of charge of the supply battery, within the reach of a person skilled in the art.

With reference to Figures 14 and 15, a machine for duplicating keys in mobility according to an alternative embodiment of the present invention is shown, which differs from the duplicating machine 100, described above and illustrated in Figures 1 to 13 A, due to the different positioning of the seat in which the power supply battery can be inserted and extracted.

The machine for duplicating keys in mobility, indicated in general with the reference number 1100, therefore comprises a seat 124 for housing in an extractable way the power supply battery 50, which is formed in the rear portion P2 of the machine at the fixed part 21 of the protective casing 20, on the opposite side with respect to the work space of the duplicating machine 1100. The seat 124 extends horizontally inside the duplicating machine 1100. As a result, the power supply battery 50 is inserted and extracted into and from the housing seat 124 according to a horizontal direction, i.e. parallel to the support plane for the duplicating machine 1100. When in position in the duplicating machine 1100, the power supply battery 50 can be completely housed in the seat 124 or, alternatively, partially housed and therefore projecting rearwardly with respect to the fixed part 21 of the protective casing 20, i.e. also cantilevered with respect to the rear part 11-2 of the base 11 see figure 14). At the same time, the seat 124 can be shaped so that the battery 50, when inserted in the seat itself, remains partially surrounded by the rear part 11-2 of the base 11.

Furthermore, a pair of guides 125 is formed inside the seat 124, to facilitate the insertion and extraction of the power supply battery 50 into and from the seat 124. In the seat 124 there are also formed electrical contacts (not shown) for the power supply battery 50. The guides 125 can be entirely similar to the guides 25, described above with reference to the duplicating machine 100, therefore they will not be described further.

Finally, and with reference to Figures 16 and 17, a machine for duplicating keys in mobility according to yet another alternative embodiment of the present invention is shown, which differs from the duplicating machine 100, described above and illustrated in the Figures 1 to 13 A, due to the fact that the seat for the removable coupling of the power supply battery, instead of being inside the fixed part 21 of the casing 20, is substantially outside it.

The machine for duplicating keys in mobility, indicated in general with the reference number 2100, therefore comprises a seat 224 for the removable coupling of the power supply battery 50, wherein this seat 224 is formed in the rear portion P2 of the machine 100 at the fixed part 21 of the protective casing 20. Also in this case, the seat 224 extends vertically outside the duplicating machine 2100. As a result, the power supply battery 50 is inserted and removed into and from the seat 224 according to a vertical direction, i.e. orthogonally to the support plane PO (indicated in Figure 16) for the duplicating machine 1100. Preferably, the seat 224 is obtained in a rear wall 211 of the fixed part 21 of the protective casing 20, i.e. the most distal wall from the front portion Pl of the machine 100 defining the work space. However, in an entirely equivalent way, it can be formed in a side 222 or upper wall 223 of the fixed part 21 (see Figure 17).

Furthermore, a pair of guides 225 is obtained inside the seat 224, to facilitate the insertion and removal of the power supply battery 50 in and from the seat 224. In the seat 224 there are also formed electrical contacts (not shown) for the power supply battery 50. The guides 225 can be entirely similar to the guides 25, described above with reference to the duplicating machine 100, so they will not be described further.

In a variant, the external seat, instead of extending vertically, can extend horizontally outside the duplicating machine, for example below the base 11 of the duplicating machine. In this case, the power supply battery 50 is inserted and removed in and from the housing seat 224 according to a horizontal direction, i.e. parallel to the support plane for the duplicating machine 1100.

From the above description, the characteristics of the machine for duplicating keys in mobility of the present invention are evident, as are the relative advantages. In particular, the machine for duplicating keys in mobility according to the invention is such as to avoid accidental switching off during operation. Furthermore, the machine for duplicating keys in mobility according to the invention can be easily used even in conditions of reduced or limited space. Finally, it is clear that the machine for duplicating keys in mobility thus conceived is susceptible to numerous modifications and variations; moreover, all the details can be replaced by technically equivalent elements.
