Description

Product Display Apparatus

FIELD OF THE INVENTION

This invention relates to consumer product advertising/display apparatus, in particular advertising/display cabinets used to promote merchandise.

BACKGROUND TO THE INVENTION

Consumer product advertising/display systems are used on shop floors, in window displays, at exhibitions or in office reception areas to display products and provide information and other material to shoppers or passers-by.

To allow different types of products to be displayed, many conventional display systems are in the form of configurable shelving systems or racks comprising a backplane to which brackets and shelving can be secured. The positioning of shelving is configurable depending on display requirements. Such shelving systems are also generally quite large, taking up significant space. It can also be difficult to create displays with shelves facing in different directions and thus often racks can only be placed against a wall or back to back. The latter case requires multiple racks.

Such display systems often require lighting. In some cases the lights are separate components which are mounted onto the displays and which require a power supply. In many cases this leads to extension cables trailing over the display racks. Some such systems, such as that shown in U55695261, incorporate internal conductors into vertical members allowing lights to be mounted on top of the shelving. In US 2002/0085373 adjacent vertical members are of differing polarity, allowing connection of electrical appliances to a low voltage power source provided by the vertical members.

As technology has developed, promoting products has become more advanced.

Product advertising/display systems often use multimedia, providing user interactivity.

Such capabilities are designed to catch the eye of a passer-by, engage a user, collect feedback and allow interaction. These more advanced display systems require more than power distribution, and requirements often vary from display to display.

The present applicant has recognised the need for an improved display system in particular a modular consumer product advertising / display cabinet that is both aesthetically pleasing and easily reconfigurable and adaptable to display and advertising requirements.

SUMMARY OF THE INVENTION

According to a first aspect of the invention there is provided a stackable consumer product advertising/display unit comprising: a housing having a plurality of faces; a first interface on a first face of the plurality of faces, wherein the first interface is configured to electrically connect the stackable display unit to a second stackable display unit to transmit power between the stackable display unit and the second stackable display unit; a second interface on a second face of said plurality of faces, wherein the second interface is configured to electrically connect the stackable display unit to a third stackable display unit to transmit power between the stackable display unit and the third stackable display unit; and an electrical coupling between the first interface and the second interface, wherein the electrical coupling is configured to electrically connect the second and third stackable display units to one another via the stackable display unit when the stackable display unit is connected to the second stackable display unit via the first interface and when the stackable display unit is connected to the third stackable display unit via the second interface.

The fact that the display units are stackable and electrically connectable means that power is routed through each display unit, with one display unit providing power to the next stacked unit. This means that a power source only needs to be coupled to one of the display units; power is then distributed to all the display units coupled via interfaces.

In some embodiments the first and second interfaces may be positioned on opposed faces of the housing such that the display units may be stacked vertically or horizontally. The stackable display unit may be cuboid shaped.

In some embodiments the first interface may be further configured to transfer data between the stackable display unit and the second stackable display unit when the stackable display unit and the second stackable display unit are coupled to one another by the first interface. This enables data to be communicated between the first and second display units as well as power, meaning that one or more of the display units may house electrical devices or components to receive and act on this data. In some embodiments display units may also act as a data source, communicating data via the first interface.

In some further embodiments the second interface is configured to transfer data between the stackable display unit and the third stackable display unit when the third stackable display unit and the stackable display units are coupled to one another by the second interface. The first and second interfaces on the stackable display unit may be further configured to transmit data between the second stackable display unit and the third stackable display unit via the stackable display unit. In other words, three display units coupled to one another may transfer data between all three display units. For example a set of display units coupled in series may allow a central unit of the three to communicate data between the two display units each coupled to one side of the central unit. Display units may communicate directly with others, or in some embodiments they may communicate via a master server, housed within one of the display unit or in a base unit according to the second aspect of the invention.

In some embodiments the stackable display unit may comprise a processing module configured to receive data from one or both of the first and second interfaces. This means that, with data transferred via one of the interfaces, the processing module may receive and/or communicate data. Data may also be routed through the processing module so that other processing modules in other display units may also receive and/or communicate data. In other embodiments not incorporating a processing module, data may also be transmitted through the display unit to the interfaces. The interfaces may be such that display units not incorporating processing modules may still be interoperable with those that do communicate data.

In some embodiments the stackable display unit may further comprise a powerline module coupled to the processing module and to the first and second interfaces, wherein the power line module is configured to communicate data between the processing module and the first and second interfaces. In other words, the data maybe overlaid, by modulating high frequency signals for example, onto the power lines such that the data is communicated via the electrical couplings providing power.

Compatibility between display units incorporating processing modules and those that do not is then provided as all the stackable display units provide a power coupling between their first and second interface.

In some embodiments the first interface may be adapted to engage with a corresponding interface on the second stackable display unit; and the second interface is adapted to engage with a corresponding interface on the third stackable display unit.

In other words, corresponding interfaces are coupleable to one other such that a connection may be made to communicate power, and further communicate data in embodiments providing data communication.

In some embodiments the first interface may be adapted to engage with a corresponding interface by one of the first interface and its corresponding interface comprising a plug and the other of the first interface and its corresponding interface comprising a socket. Furthermore, in some embodiments the second interface may be adapted to engage with a corresponding interface by one of the second interface and its corresponding interface comprising a plug and the other of the second interface and its corresponding interface comprises a socket. In some embodiments a display unit may comprise an interface with a plug and another with a socket, however more of each may be provided or a display unit may only comprise the same type of interface arrangement, for example two or more plugs or two or more sockets. It will be appreciated that more interfaces may be provided and is not limited to two interfaces.

The first and second interfaces may each comprise at least one electrical terminal for transmitting power between the stackable display unit and the second and third stackable display units respectively. In further embodiments at least one of the first and second interfaces may comprise a plurality of the electrical terminals. In such an embodiment one of the plurality of electrical terminals may be coupled to a first power rail, for example a mains AC live rail (or positive DC rail), and another of the plurality of electrical terminals may be coupled to a second said power rail, for example a mains AC neutral rail (or OV DC rail).

In some embodiments at least two of the plurality of electrical terminals may be coupled to the same said power rail. This may then allow one display unit to be rotated relative to another display unit to which it is to be coupled, enabling displayed products to be viewed from different sides. By coupling two of the plurality of electrical terminals to the same power rail a power connection may then be made even if electrical terminals on one interface and the corresponding interface on another display unit are rotated relative to one another -a power connection may be then maintained irrespective of the orientation of the plug relative to the socket for example In some embodiments the first and second interfaces are further configured to transmit data across the same electrical terminals. In other words, when, for example, using a power line interface, no further electrical terminals may be needed on the interfaces to communicate data.

In other embodiments the first and second interfaces may each comprise at least two said electrical terminals, wherein at least one of the at least two electrical terminals is configured to transmit power and wherein another of the at least two electrical terminals is configured to transmit data. In other words, separate power and data electrical terminals may be provided, for example with separate power terminals and separate data terminals. The data terminals may be, for example, a conventional network interface plug, such as an RJ45 plug, on one interface and a network interface socket, such as an RJ45 socket, on the other.

In some embodiments at least one electrical terminal on the first interface may comprise a contact surface arranged to engage with a corresponding contact surface on the corresponding interface on the second stackable unit. In other words, rather than a plug and socket arrangement, at least one electrical terminal may comprise a surface arranged to touch another on the corresponding interface on the second stackable unit. One of the surfaces may be a flat metal plate for example, and the other a conductive rod biased, by a spring for example, to provide contact with the plate when the two display units are sat one on the other. In variants, at least one electrical terminal may comprises an annular conductive ring; two electrical terminals may then be provided through the use of two concentric annular conductors.

In other variants, at least one said electrical terminal may comprise an inductive power loop. This means that no physical coupling of electric terminals may be necessary. The inductive power loop may be positioned near to and under the surface of the face having the interface. Similarly, on the second display unit, the inductive power loop may be correspondingly positioned on the face with the corresponding interface. This means that when the display unit is coupled to the second display unit, the inductive loops magnetically engage such that power may be communicated. Optionally data may be also communicated in embodiments supporting data.

In some embodiments at least one of the first and second interfaces may comprise a projection which engages in a recess having a complementary profile in the corresponding interface. In other embodiments at least one of the first and second interfaces may comprise a recess having a complementary profile to a projection on the corresponding interface. In some embodiments the projection or recess may be generally cylindrical, allowing one display unit to freely rotate relative to another about the generally cylindrical interface. In other embodiments the projection or recess may be generally in the shape of a cuboid. In such an embodiment the display units may then be limited to being positioned in four different positions relative to one another.

These positions may allow the display units to be positioned, for example, with both facing the same direction, facing opposing directions, or rotated 90 degrees relative to one another.

In some embodiments one of the first and second interfaces may comprise a projection and the other of the first and second interfaces may comprise a recess in the housing.

The projection and recess may be arranged such that when the stackable display unit is coupled and stacked with the second stackable display having a corresponding second interface, the interfaces form a flush connection such that the projection is not visible. In other words, the projection on the one interface may be sized such that it fits snugly into the recess on the other interface to conceal the projection and recess.

It will be appreciated that the first and second interfaces need not be different. In some embodiments a display the first and second interfaces may be the same, for example one display unit may have two or more interfaces with projections, or alternatively two or more with recesses, or a combination. Varying the arrangement of projections and recesses may permit different stacking arrangements. In other variants it will be appreciated that where the first and second interfaces may be physically similar (for example, having inductive couplings or surfaces arranged to engage with one another), then there may be more freedom by which units can be coupled to one other.

In some embodiments of the stackable display unit at least one of the first interface and said second interface may be rotatable relative to the housing. This may allow the display units to be rotated or turned relative to one another to display merchandise in different directions. By allowing the interface to be rotatable relative to the housing, this may allow display units to be turned relative to one another even on embodiments where the interfaces may need to be coupled in a fixed orientation. A plug that may need to be connected to a socket on another unit in a fixed orientation for example, may be rotated relative to its housing such that the connection can be provided.

In some embodiments of the stackable display unit, the stackable display unit may further comprise a power point coupled to the electrical coupling. This may be used to power an electrical item, such as a light source; and/or provide a power or charging point for a product on display.

In some embodiments the stackable display unit may further comprise an inner wall in the housing, wherein the inner wall is spaced apart from the housing so as to form a void between the inner wall and the housing. This void may be used to conceal constructional elements of the housing. Furthermore, in embodiments the electrical coupling, provided by a multi-core electrical cable for example, between the first interface and the second interface may be routed through the void between the inner wall and the housing such that it is concealed.

In some embodiments a third face of the plurality of faces on the stackable display unit may be open or may comprise a transparent window. The housing may then comprise a platform viewable through the open face or transparent window for displaying a product.

In some embodiments, the stackable display unit may further comprise a multimedia display screen viewable from at least one face of the housing. This multimedia display screen may be powered by coupling to the power point, and may be coupled to the processing module to drive the display. User input means, such as a touchscreen interface may be further provided to allow interaction with the display unit, for example to allow selection of videos and to allow a shopper to enter information, such as a contact details to request information on the product. In some embodiments the multimedia display screen may be partially transparent such that a product may be displayed on a platform behind the display and viewed through the multimedia display screen.

According to a second aspect of the invention there is provided a modular consumer product advertising/display stand comprising a plurality of stackable consumer product advertising/display units according to the first aspect of the invention.

The modular consumer product advertising/display stand may further comprise a base unit. The base unit may comprise: a housing having a plurality of faces; and a first interface on a face of the housing of the base unit. The first interface may be configured to electrically connect the base unit to one of the plurality of stackable display units to transmit power from the base unit to said stackable display unit.

The base unit may comprise a power source, for example a battery. Additionally or alternative the base unit may be couplable to a mains power source such as a mains AC interface. In some embodiments the battery may charged by coupling the base unit to mains electricity. The batter may be part of an uninterrupted power supply (UPS). In embodiments providing an AC power coupling between display units, when powered by a battery, the base unit may further comprise an inverter to convert a DC voltage from the battery to an AC output. In embodiments providing DC power coupling between display units, when powered by mains, an AC to DC converter circuit may further be provided.

In some embodiments the base unit may further comprise a processing module configured to communicate data between the base unit and the stackable display unit when coupled to one another. This processing module may act as a data server for example, communicating data to other stacked display units. It may further receive data from other stacked display units, for example storing data entered by shoppers who have requested further information or asked to join a mailing list from the manufacturer.

In some embodiments the modular consumer product advertising/display stand may further comprise an interface cover, wherein the interface cover is arranged to cover a visible interface on the housing of any one of the plurality of stackable units. This may then protect the interface to prevent a passer-by touching electrically conductive parts of the interface.

According to a third aspect of the invention there is provided a stackable consumer product advertising/display unit comprising: a housing having a plurality of faces; a first interface on a first face of the plurality of faces, wherein the first interface is configured to electrically connect the stackable display unit to a second stackable display unit to transmit power between the stackable display unit and the second stackable display unit; a second interface on a second face of the plurality of faces, wherein the second interface is configured to electrically connect the stackable display unit to a third stackable display unit to transmit power between the stackable display unit and the third stackable display unit; and an electrical coupling between the first interface and the second interface, wherein the electrical coupling is configured to electrically connect the second and third stackable display units to one another via the stackable display unit when the stackable display unit is connected to the second stackable display unit via the first interface and when the stackable display unit is connected to the third stackable display unit via the second interface, wherein the first interface is adapted to engage with a corresponding interface on the second stackable display unit; and wherein the second interface is adapted to engage with a corresponding interface on the third stackable display unit.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Herein when we refer to display units or cabinets, we encompass display units/cabinets capable of holding products for display, capable of providing advertising, multimedia displays and the like (via an LCD screen for example) and interactive displays, such as touch screens allowing users to engage with the promotional display.

The modular display cabinets described herein are stackable. This means that they may be coupled together, one on top of another, or side by side. Combinations of both may also be possible to create multi-dimensional displays.

Figure 1 shows a 3D projection of a stackable modular display cabinet 10 positioned on a base cabinet 16. The display cabinet (also referred to as a display unit) 10, as depicted, comprises a housing having a front transparent face or panel 12 that may be removed or opened to allow a product to be placed on a platform inside the cabinet.

The other sides, or faces, of the cabinet in the illustrative example are solid and non-transparent.

A second cabinet (not shown) may be stacked on top of the display cabinet in a vertical arrangement. The two units may be held in place by an interface in the form of a plug 14 on the top face 18 of the display cabinet mating with a complementary socket on the base of the second cabinet. If the second cabinet also has a plug 14 on its top surface, it will be appreciated that a third cabinet having a corresponding socket may be stacked thereon. Multiple cabinets may thus be stacked in the vertical direction.

Similarly, the base cabinet 16 also comprises a correspondingly positioned plug to interface with a socket (not shown) on the base of the display cabinet. The cabinets may also be stacked in a horizontal arrangement by rotating the cabinets by 90 degrees such that the plug and sockets still interface to connect the cabinets together.

In other variants, not depicted, a cabinet may have sockets on two faces, and plugs on two faces, enabling coupling to take place in both horizontal and vertical directions.

By varying the number of sides of the interface plug and socket, the display cabinets may be positioned relative to one another in multiple different positions. A circular interface on a face for example allows the cabinets to be rotated relative to one another to any position; a square interface plug and socket limits the number of different positions to four.

The plug 14 on the top face 18 of the cabinet also forms a cabinet to cabinet interface which allows power and/or data to be transferred between multiple stacked cabinets.

Further securing means may be used to hold the display cabinets, if the cabinet to cabinet interface is not sufficient to hold the cabinets in place. Further details of the interface, including variants of the plug and socket are discussed later with reference to Figures 4a-4j.

Figure 2a shows a front view of the display cabinet 10 of Figure 1, showing the transparent window/door 12 allowing a product to be displayed in the cabinet chamber.

It will be appreciated that the use of a transparent window/door is optional -there may just be an opening to the display platform.

Figure 2b shows a cross-sectional side view of the display cabinet of Figure 1 along the line C-C of Figure 2a, and Figure 2c shows a cross-sectional top down view of the display cabinet of Figure 1 along the line A-A shown of Figure 2a. From these Figures, it can be seen that the display cabinet further comprises an inner wall within the housing. The inner partition wall runs generally parallel to three panels of the housing (the rear and two sides). A void 15 is formed between the housing panels (side and rear 19) and the inner partition wall 17. The void 15 conceals power and/or data wires routed from the cabinet to cabinet interfaces (top and base). The void may also be used to conceal other electrical wires, such as those tapped off the power wires to provide a power point to power lights or other electrical components within the display cabinet (electronic devices, such as microcontrollers, or displays for example) . This void also conceals constructional components of the housing, such as fixings holding the housing and partition wall in position. The inner partition wall 17 may be interchangeable in some arrangements of the display cabinet, allowing partition walls with different colours, embellishments or features to be used.

Figure 2d shows a plan view of the display cabinet 10 of Figure 1. Here further details of the top panel 18 can be seen along with the cabinet interface plug 14.

Figure 3 shows an exploded view of the display cabinet embodiment of Figure 1, showing the cabinet construction. The cabinet comprises a housing having a plurality of faces, namely a front panel 12, a base panel 27, two side panels 21, a front panel 12 and a rear panel 19. The front panel 12 may be secured to the housing via a hinge or by slotting into the housing. Retaining members 25 extend vertically from each corner of the base panel 27, providing slots into which the side panels 21 and rear panel 19 fit.

Upper panel 18 is coupled to other components of the cabinet via an intermediate upper panel 29 which comprises a recess to define a void between the upper panel 18 and intermediate upper panel 29 allowing wires to be routed through to the cabinet interface 14. Similarly, the base panel 27 is coupled to an intermediate base panel 31 which creates a void between the cabinet base panel 27 and intermediate base panel allowing wires to be routed to the interface socket 15. The presence of a void also allows the interface socket 15 to be recessed into the base panel 27 so as to engage with an interface plug 14 from a base cabinet 16 or another display cabinet 10. This way, the interface is hidden when one display cabinet is mounted on another.

Within the housing, there is an inner partition wall 17 having a generally U" shape with curved rear corners. The inner partition wall 17 defines a presentation chamber which makes the display area more visually appealing.

Turning now to Figures 4a-4j, these show example embodiments of the cabinet to cabinet interface.

Figures 4a show a plan view of a first embodiment of the cabinet interface plug 14 positioned on the top panel 18 of the display cabinet 10. This embodiment corresponds to that previously shown in Figures 1-3. Figure 4b shows a side view of the interface plug of Figure 4a arranged to engage with the interface socket 15 on the base of another display cabinet or base cabinet.

The interface plug 14 is formed as a shallow cylinder projecting from the top panel of the display cabinet. As clearly shown in Figure 4a, this means that the interface plug has a circular cross-section in a plane parallel to the top panel face. This allows one cabinet to be rotated freely relative to the other.

The interface plug comprises a pair of electrical terminals 45, 46 formed as conductive concentric rings. These provide an electrical coupling between the interface plug on one display cabinet and the interface socket on another display cabinet.

On the interface socket 15, a pair of corresponding concentric rings, or alternatively two or more conductive pins 35, 36 (at least one for each connection) are arranged to align and engage with the plug conductors when two display cabinets are coupled/stacked on one another. In the illustrative embodiment in Figure 4b, the rings, or pins, herein more generally referred to as socket electrical connectors or terminals, are mounted on springs biasing the socket electrical connector down and towards the plug. This way, the connector can move in the vertical direction (as depicted in Figure 4b) ensuring the rings or pins maintain contact and provide an electrical connection. In variants it will be appreciated that the plug electrical connector may additionally or alternatively be sprung to provide similar capabilities.

The connections distribute power, either DC or AC. With a DC connection one connector may provide a +V power rail and the other connector may provide a OV power rail. With an AC power connection, one connect may provide the Live' power rail and the other connector may provide the Neutral' power rail. It will be appreciated that in some countries safety requirements may also dictate a third connection for AC voltage so that a ground rail is also provided. The connectors allow power to be transferred between cabinets discreetly, avoiding unsightly wires trailing down one side of the cabinets.

The interface may also allow data to be transferred between cabinets, either using the same two electrical connectors using power line communication over AC electricity or by providing additional connectors. Further details are described later with reference to Figures 5a, Sb and 6. Communicating data over the power connections means the internal pin count does not need to increase. Furthermore, any cabinet not having a device requiring data may then simply pass the data through with no change to the interface. This means that the cost of the simpler, product display only cabinets is kept to a minimum whilst still being compatible with other display cabinets requiring a data connection.

In Figure 4a and 4b, sprung spherical lugs 43 project from the sides of the interface plug to provide a secure, but removable, connection into a corresponding interface socket 15. Pushing the plug into the socket forces the springs to compress and the lugs to recede into the socket until the lugs align with corresponding recesses 41 around the edge of the socket. In this way one cabinet may be secured on top of another and held in position in which at least one, but preferably more, of the lugs engage with a corresponding recess on a socket. Depending on the arrangement and positioning of the lugs and recesses, a display cabinet may be secured in one or multiple different positions relative to the display cabinet or base cabinet it is mounted on to. In the embodiment of Figure 4a, four different positions are possible with all lugs equally spaced apart positioned at 90 degrees from the other around the edge of the interface socket. This means that if a cabinet is accidentally knocked or pushed the electrical connectors on the plug and socket remain in contact with one another. Four is merely an illustrative number. As the skilled person will appreciate, many other variants of securing one cabinet to the other are possible and the example described herein and depicted in Figure 4a and Figure 4b is one illustrative embodiment.

Figures 4c and 4d show plan and side views respectively a second embodiment of the cabinet to cabinet interface. In this embodiment, the circular cabinet interface is replaced with an interface plug 44 with a square cross section, limiting the number of positions that a cabinet may be positioned on top of another to four. This inhibits free rotation of one cabinet mounted on another, meaning that the cabinets may be more easily aligned. Other features of the interface, e.g. the conductors, are the same as Figure 4a and thus are not described in detail.

Figure 4e shows a plan view of a third embodiment of the cabinet to cabinet interface using a rotatable socket and/or plug. This allows cabinets to be rotated relative to one another whilst maintaining power and, if used, data communications between cabinets sat one on top of another. The socket/plug may be two-way, providing a power coupling with optional powerline communication for data over the same wires/electrical terminals. In variants the number of individual connections may be increase to four-way, eight-way or more, providing one or more data channels such as serial communications or Ethernet.

Figure 4f shows a side view of a fourth embodiment of the cabinet to cabinet interface using a conventional wired connector. In this embodiment, the connector plug 402 may be coupled to an extendable cable stored within one of the voids in the cabinets, allowing a run of cable to be pulled out of one cabinet for connection to a socket 404 on the base of another cabinet, then returned either by manual or automatic rewind, into the voids when one cabinet is sat on top of another. Again power connections may optionally provide powerline communication, or separate data connections may be provided.

Figure 4g shows a side view of a fifth embodiment of the cabinet to cabinet interface using inductive coupling. In this variant, inductive coupling elements 406, 407, avoid the need for physical engagement of a plug and socket. Couplings may be positioned below the surface of top panel 18 and above the surface of base panel 27 such that there are not directly visible from the outside of the cabinet. This way, there is no need to cover over the top panel of the uppermost cabinet to hide any connectors. Such connections may again provider power and/or data.

In a variant of the rotatable plug/socket of Figure 4e, Figures 4h-4i show details of a sixth embodiment of the cabinet to cabinet interface allowing cabinets to be coupled and positioned in steps of 90 degrees relative to one another. In this variant, two power rails P+ and A-and two data rails D+ and D-are routed between cabinets, requiring a 4 way connection. On the plug 407, the 4-way connection is repeated as shown in the Figures 4i, 4j, 4k, 41 into each quadrant of a 16-way plug with connections rotated. As shown in the upper drawings in Figures 4i-41, the socket is wired in only one quadrant, meaning that one cabinet may be positioned on top of another in four different positions and the correct connectivity is still provided as the power and data lines correctly align to ensure no cross wiring. In another variant, the socket and plug connections may be reversed, so that the connections are replicated on the socket. It will be appreciated that providing four different positions is an illustrative embodiment and more or less positions may be possible.

It will be appreciated that a similar approach may be used to provide different numbers of individual connections. If powerline communications are used, only the P-i-and P-connections for power are repeated.

In any of the described interface embodiments, the upper interface on the top panel of the cabinet may also be moveable such that it can be recessed into the cabinet when not required, then, through the use of a push to open latch, allowed to pop up out of the cabinet when a further cabinet is to be mounted on the top. In this way there may be no need for a top cover, as each cabinet may have a built in cover that can slide open to reveal the interface and plug/socket, then close to conceal the interface and plug/socket.

Figures 5a and Sb show schematic block diagrams of the base cabinet and describe further details of how power and, if required, data may be communicated between the display cabinets. In the example embodiments shown, a base cabinet incorporates power, control and computer processing hardware. In variants however it will be appreciated that such features may be incorporated into a display cabinet, using for example, the voids between the display chamber and outer housing to hide such hardware. A base cabinet may then not be required.

Referring now to Figure 5a, this shows a schematic block diagram of a first embodiment of the base cabinet 16 adopting the interface of Figures 4a and 4b and incorporating powerline technology to allow data communications over the power connections.

Base cabinet 16 includes a power unit 50 coupled to mains AC input 57. Optionally conventional battery power 54 or UPS 52 capabilities may also be provided.

A processing unit 56, provided by a computer or microcontroller, provides a data/network server providing a source of data (media files and the like) for sending to data enabled cabinets. The processing unit preferably includes storage, such as a hard disk or flash memory. The data enabled cabinets may be network bootable, requesting and receiving firmware I code to execute from the processing unit. The processing unit may also store data received from data enabled cabinets, storing and/or communicating data entered by users interacting with the data enabled cabinet.

Depending on the data processing requirements, the processing unit may be a laptop, desktop, single board computer or microcontroller such as a Raspberry Pi Arduino, Picaxe or mbed.

A control/data port 50 provides access to the processing unit, allowing an operator to configure and control the processing unit. This may be a network port for example allowing a user to remotely login and configure the processing unit. In variants, a wireless interface may also be used, eliminating the need for a physical port.

Coupled to the power unit and processing unit is a powerline interface allowing data to be transmitted simultaneously over the power connections 45, 46 between cabinets.

The powerline interface may be a powerline module with communications preferably conforming to the HomePlug AV and/or IEEE 1901 standards specifying how AC mains power lines may be used for data purposes.

The data connection enables a data network to be formed between the base unit and display cabinets having their own processing modules. In this illustrative example in which powerline communication is used, A display cabinet requiring a data connection includes a corresponding powerline module to extract and overlay data onto the power rails.

Display cabinets on this network may then be assigned a unique network address, such as an IP address. This allows the processing unit to identify, register and communicate directly with any data enabled display cabinet. The processing unit may also act as the network router to assign IF addresses. Alternatively a separate network router coupled to both the processing unit and powerline interface may be used.

In a variant of the base cabinet of Figure 5a, separate data connections may be provided, adopting the interface of Figures 4e or 4f for example. Separate wires are used for the data channel, forming a separate serial or Ethernet connection for

example.

Figure 6 shows an example implementation of the modular display cabinet system using two interconnected display cabinets 10, 61 positioned on a base cabinet 16.

The base cabinet 16 in Figure 6 uses powerline technology as described with reference to Figure 5a.

Display cabinet 10, labelled Unit #1', includes a presentation chamber covered by a transparent panel 12. Lights 64 positioned within the presentation chamber each require power. No data is required for this display cabinet. Unit #1 sits on top of base cabinet 16, interfacing via the cabinet to cabinet interface allowing power to be provided by the base cabinet. In Unit #1 the power rails are routed via wire through the void between the display cabinet housing and presentation chamber through to the top panel and upper interface plug on Unit #1.

Display cabinet 61, labelled Unit #2', includes a display 68 instead of transparent panel 12. In this example the display also incorporates a touch screen. A microcontroller 66 (or more powerful computer if more complex processing is required) is used to drive the display and process any feedback from user interactions with the touch screen. In some embodiments the display in Unit #2 may also be transparent, meaning that one or more products may still be displayed behind the display.

Unit #2 is stacked on top of Unit #1, with both power and data, via powerline technology, communicated to Unit #2 from the base cabinet via Unit #1.

The microcontroller 66 is also coupled to the powerline interface allowing the microcontroller to request a dynamically assigned IA address from the processing unit/router in the base unit. Alternatively the microcontroller may have been assigned a static IF address for that particular display unit.

The microcontroller 66 may also be used to control parameters of the display cabinet, such as light intensity, light colour and powering the display cabinet on or off. The processing unit in the base unit may also be able to communicate with the microcontroller to command and control the parameters. This may be used, for example to provide global control of all the data enabled display cabinets. Furthermore, this may also allow for synchronisation between display cabinets, simultaneously controlling light or colour changes and/or switching on and off lighting in patterns for

example.

Unit #2 is used to provide videos, animations, and engage users. If an optional user interface is provided, such as a touch screen, then the user may interact to select videos to watch, view more information, enter contact information to join mailing lists or purchase one of the products on display, either in the same display cabinet or another.

Such information may then be communicated to the processing unit in the base cabinet. Periodically the processing unit, if provided with an external network connection, may then communicate this data to a remote computer.

The microcontroller may also include non-volatile memory allowing videos or programs to be locally stored and automatically loaded when a power connection is made between Unit #2 and Unit #1. Alternatively, the microcontroller may load data over the network, receiving data from the processing unit 56 in the base cabinet. In this way, functionality, videos, and other information can be delivered directly by the processing unit or via the control/data port in the base cabinet.

A top cover 92 is positioned on the top panel of Unit #2 to cover the cabinet to cabinet interface 14 and protect against touching of the power connectors. This cover may be used to cover visible interfaces on the housing of any one of the stackable cabinets.

Figure 7 shows a second arrangement of interconnected display cabinets positioned on a base cabinet. In this more advanced variant, wired data communications between cabinets is limited to power transmission only. Power is transmitted in the same way as described with reference to Figure 6. Data communication is provided by wireless interface 72 (typically a wireless hub) in the base unit and wireless interface 72 in Unit #2. In the event that multiple display columns are present, each with their own base cabinet and processing unit, it may be necessary to register a a display cabinet is communicating with the correct base cabinet before use. Alternatively, a display cabinet may be registered with another base unit to allow such a display cabinet to communicate with a physically separate base unit, but receive power from the physically coupled base unit.

Figure Ba shows an example of a lit product display 84 in the display cabinet of Figure 1. Here two display cabinets 10 are positioned one on top of the other, each lit by respective lights 64. Shown in Figure Sb, a translucent Perspex mount 82 is used to raise the positioning of the product 84 on display, further allowing the product to be lit from below.

Figures ga-gd show example configurations of the module display cabinet system. The example configurations are shown with a separate base cabinet 16 and top cover 92.

In other variants it will be appreciated that components of the base cabinet may be incorporated into one of the display cabinets. Such a display cabinet may then be designated a master' display cabinet, providing capabilities to control other display cabinets and distribute power. Other display cabinets may then accordingly be designated as slave' display cabinets.

Figure 9a shows a first vertical arrangement of display cabinets with a base cabinet 16 holding a single display cabinet 10 and top cover 92.

Figure 9b shows a second vertical arrangement of display cabinets with a base cabinet 16 and top cover 92. In this example arrangement, display cabinet 10 labelled Unit #1 is stacked on the base cabinet. Unit #2 is rotated by 180 degrees such that a product is displayed in the opposite direction. Cabinet 101, labelled Unit #3 and having an display with touchscreen control is then rotated a further 180 degrees, facing the same direction as Unit #1.

Figure 9c shows a third vertical arrangement of display cabinets with a base cabinet 16 and top cover 92. In this example arrangement, Unit #1 provides a double height display. Unit #2, stacked on top of Unit #1 allows one or more products to be displayed.

Figure 9d shows an arrangement of horizontal display cabinets with a base cabinet 16 and top cover 92. In this arrangement, the base cabinet is positioned at one end of the horizontal display, and a top cover is mounted onto the other end. The horizontal display may be positioned on the floor, on a shelf, or each secured to a wall. In this example, Unit#1 and Unit #3 each provide an area for product display, and Unit #2 allows for user interaction, including a touch screen interface allowing a user to research and read more information about the products on display.
