Description

Attaching an Object to a Panel

The present invention relates to attachment of an object to a smooth panel. According to one aspect of the invention there is provided an arrangement for attaching an object to a smooth panel, comprising a static cling film attachable to the smooth panel, and a fastener for arrangement between the static cling film and the object and for fastening to both. Preferably the static cling film is a polyvinyl chloride) film. Polyvinyl chloride) can provide particularly beneficial properties with respect to transparency, strength and durability.

For favourable transparency and strength the static cling film is preferably 80 to 280 μηι thick, more preferably 160 to 200 μηι thick, and yet more preferably 180 μηι thick.

For stability, the arrangement is preferably such that the object can be asymmetrically positioned on the film.

According to another aspect of the invention there is provided an arrangement for attaching an object to a smooth panel, comprising a film arranged to be attachable to the smooth panel without adhesive, and a fastener for fastening the object to the film.

The fastener is preferably arranged to be positioned between the object and the film.

The film may comprise a plurality of suction cups provided on a surface for providing adhesion to the smooth panel. The suction cups may be microscopic. The film may comprise polypropylene.

For attachment strength the touch fastener is preferably of a type having mushroom-shaped interlocking stems. To ensure a thin profile, the fastener may be flat and/or planar. For reusability, the fastener is preferably arranged to be releasably fastened. Preferably, the arrangement is such that a side of the fastener that is not fastened to the film is fastened to the object.

For visibility, a region of the film adjacent a region of panel to which the object is to be attached is preferably devoid of fastener. For ease of attachment the touch fastener is preferably for fastening to the film and/or the object with a pressure sensitive adhesive.

For attachment strength the touch fastener is preferably for fastening to the object with a threaded member, preferably a screw.

For visibility of an object through the film the film is preferably transparent. For an attractive appearance the film may carry a decoration, preferably wherein the decoration is printed on the cling film. To provide visibility through the film, a region of film within the surface decoration is preferably devoid of print so as to provide at least one aperture through which an object on the other side of the film can be viewed.

According to another aspect of the invention, there is provided a film arrangement, comprising a film having a first surface attachable to a smooth panel without adhesive and a second surface with a surface decoration printed on it, wherein a region of film within the surface decoration is devoid of print so as to provide at least one aperture through which an object on the other side of the film can be viewed. The at least one aperture may have a size and shape that generally corresponds to the size and shape of a display monitor. Preferably, the at least one aperture defines a generally rectangular shape of about 1500 mm x 1000 mm, more preferably 975 mm x 575 mm, preferably about 700 mm x 400 mm, more preferably about 450 mm x 250 mm, and yet more preferably about 385 mm x 220 mm. A plurality of apertures may be provided within the surface decoration. Once a decorative pattern has been printed onto a film, such as a static cling film, the resulting article may be referred to as "printed vinyl", for example. The film may be sized as a sheet of material or "poster". The surface decoration pattern may be in the form of artwork, such as that provided on an advertising or marketing display poster, or similar, such that the sheet of printed film resembles such a poster. Furthermore, the decorative pattern may provide a surround to the, or each, aperture, which puts the, or each, aperture at the centre of focus of attention, or draws a viewer's eye to the, or each, aperture, when viewing the poster. The poster may be provided with a header portion, to attract attention.

For avoiding the back plate providing an unwanted shadow or darkened background, a region of the film having printed on it a surface decoration may be arranged to extend past the back plate, whereby said region of film may provide space for a title, a header or similar - if the arrangement is to be used as a display poster, for example.

For a secure attachment, the fastener is preferably spaced from the aperture. Preferably, the fastener is arranged above the aperture, in use.

For stability, the aperture is preferably asymmetrically positioned on the film. The asymmetry may be such that, in use, an amount of film visible above the object or aperture is greater than the amount of film visible below the object or aperture.

According to another aspect of the invention there is provided a back plate for mounting a display monitor to a smooth panel using an arrangement as described above, the back plate having a cavity spaced from the peripheral edges of the back plate for receiving a display monitor.

To aid cooling, the cavity preferably comprises at least one formation for supporting a display monitor spaced apart from a base of the back plate. Preferably, the at least one formation is spaced about 5 to 30 mm, preferably about 5 to 20 mm, preferably about 5 to 15 mm, and yet more preferably about 10 mm, from the base of the back plate. To be suitable for use with a display monitor, the cavity is preferably generally rectangular, and/or wherein the at least one formation is may be provided towards a corner of the cavity. The formation may be a chamfered corner.

To ensure a thin profile, the back plate may further comprise at least one recess that is separate from the cavity, the recess being arranged to receive a fastener.

For stability, the at least one recess is preferably provided above the cavity, in use. A further recess may be provided below the cavity, in use. A yet further recess may be provided on one or each side of the cavity, in use. The recess may be elongate to accommodate a strip of fastener. The recess may be rectangular to accommodate shorter (relative to a strip) portions of fastener. The recesses may be positioned at corners of the aperture or along the sides of the aperture, preferably spaced from the aperture, and/or may be of any suitable shape to accommodate a fastener.

To aid air flow, at least one vent may be provided in the back plate. Preferably, two vents are provided, arranged such that air can flow easily between them.

To provide a discreet status indicator, an LED may be provided inside the back plate, wherein the LED is preferably arranged to be visible through a vent (or similar opening) in the back plate. According to another aspect of the invention there is provided a system comprising an arrangement as described above.

For attachment strength the film is preferably arranged to overhang the object by at least 1 mm to at least 200 mm in at least one direction; more preferably the film is arranged to overhang the object by at least 50 mm to at least 100 mm in at least one direction; and yet more preferably the film is arranged to overhang the object by at least 75 mm in at least one direction. Preferably the film is arranged to overhang the object in at least an upward direction. For attachment strength, the film may be arranged to overhang the object or aperture asymmetrically, preferably such that the object or aperture is positioned asymmetrically on the film. The asymmetry may be such that, in use, (when attached to a panel) an amount of overhang above (or upward) of the object or aperture is greater than the amount of film visible below (or downward) of the object or aperture. Preferably, in use, the amount of film above the object or aperture is preferably at least 25%, more preferably at least 50%, more preferably at least 65%, more preferably at least 75%, more preferably at least 90% and yet more preferably at least 100% greater than the amount of overhang. For attachment strength, in use, the amount of overhang of film above an attached back plate may be roughly at least twice the amount overhang of film below the back plate. For example, the overhang may be 30 to 40 cm above the back plate and 15 to 20 cm below the back plate. More preferably, the overhang may be 36 cm above the back plate and 15 cm below the back plate.

For attachment strength preferably at least 1 cm² to at least 15 cm² of touch fastener is provided per kg weight of the object; more preferably at least 5 cm² to at least 10 cm² of touch fastener is provided per kg weight of the object; and yet more preferably at least 6.67 cm² of touch fastener is provided per kg weight of the object.

For display versatility the object is preferably a display monitor. For ease of use, the display monitor may be arranged to receive data to be displayed from a local memory source (such as a USB memory stick). For convenience and attractive appearance the display monitor is preferably capable of receiving data to be displayed by a wireless connection. With a wireless connection wiring to the display monitor can be omitted or minimised, thus reducing or avoiding the unattractive appearance of wiring to the display monitor. Alternatively, the object may be a back plate as described above, whereby a display monitor mounted in the back plate is visible through the panel when the back plate is attached to the panel.

According to a another aspect of the invention there is provided a system comprising an arrangement as described above and the smooth panel, and optionally being a system as described above.

For an attractive appearance the smooth panel is preferably a window, more preferably a glass window. Preferably the object is attached to the smooth panel such that the object is visible through the window.

According to another aspect of the invention there is provided a kit of parts for use in an arrangement or system as described above comprising a static cling film attachable to a smooth panel, and a touch fastener for arrangement between the film and an object.

According to another aspect of the invention there is provided a method of attaching an object to a smooth panel, comprising:

applying a film to the smooth panel;

applying a first touch fastener part to the film;

applying a second touch fastener part to the object; and

attaching the first and second touch fastener parts to one another such that an attachment forms. For attachment strength the method preferably further comprises wetting the smooth panel before applying the film.

For attachment strength the method preferably further comprises smoothing the film onto the panel after applying it to the panel to bring the film substantially into contact with the panel.

The film and/or the touch fastener is preferably according to the system or arrangement as described above. For reuse the method preferably further comprises detaching the object from a smooth panel. For ease of detachment the method preferably comprises disengaging the touch fastener such that the object is released from the static cling. Preferably, the method further comprises detaching the film from the smooth panel; and. Preferably detaching the film from the panel comprises: peeling a portion of the static that overhangs the object from the panel; and pulling the assembly of film, touch fastener and object from the panel. Preferably disengaging the touch fastener comprises peeling the film from the object.

applying a rigid board to the smooth panel; and

applying the object to the rigid board.

Any apparatus feature as described herein may also be provided as a method feature, and vice versa. Any feature in one aspect of the invention may be applied to other aspects of the invention, in any appropriate combination. In particular, method aspects may be applied to apparatus aspects, and vice versa. Furthermore, any, some and/or all features in one aspect can be applied to any, some and/or all features in any other aspect, in any appropriate combination.

It should also be appreciated that particular combinations of the various features described and defined in any aspects of the invention can be implemented and/or supplied and/or used independently.

Preferred features of the present invention are now described, purely by way of example, with reference to the accompanying figures, in which: Figure 1 shows a side view of the components for attachment of an object to a vertical panel;

Figure 2 shows an example of a sheet of film having a printed surface decoration with an aperture;

Figure 3 shows another example of a sheet of film having a printed decoration with a plurality of apertures;

Figure 4 shows an arrangement of a sheet of film and a display monitor;

Figure 5 shows a back plate for the arrangement of Figure 4;

Figure 6 shows another view of the back plate of Figure 5;

Figure 7 shows an arrangement of a sheet of film and a plurality of display monitors; and

Figure 8 shows a back plate for the arrangement of Figure 7.

Referring to Figure 1 , this shows the components for attachment of an object 16 (such as a video display screen) to a vertical panel 10 (such as a window). A transparent (or possibly translucent) static cling film 12 is attached to a touch fastener strip 14. The touch fastener strip 14 is formed of two opposing strips 14- 1 , 14-2 that may be identical or different, with the opposing surfaces such that they can engage with one another and fasten together, and also be released from one another by a sufficient pulling or peeling action. Of the two opposing strips parts 14-1 , 14-2 a first strip part 14-1 is attached to the static cling film 12 by means of pressure sensitive adhesive at the back of the strip 14-1 , and the other of the two opposing strips parts 14-2 is attached to the object 16 by means of pressure sensitive adhesive at the back of the strip 14-2.

As shown in Figure 1 , two fastener strips 14 extend across the object 16, one near the base of the object and one near its top. Different arrangements are possible, including only one fastener strip near the top of the object. The strip arrangement may be selected dependent on the weight balance/centre of gravity of the object. Included in the term 'fastener strip' are elongate portions cut to size from a continuous strip of material, but equally pre-formed portions of fastener, such as pre-formed discs or squares. Different shapes of fastener strips (e.g. circular, square, triangular or rectangular) and different configurations of placement can be selected. For a square or rectangular object suitable arrangements of fastener strip include: on one, some or all of the straight edges; at all four corners; or only at the top two corners of the object. For circular objects suitable arrangements of fastener strip include: a strip across the top edge; a symmetrical arrangement at the four compass points; at each of the 12 hour points; or at 1 , 2, 4, 5, 7, 8, 10 and 1 1 o'clock. A symmetrical arrangement of the fastener strip on a regular shaped object can provide better weight balance and aesthetics. For example for a rectangular screen up to 32 inches diameter an arrangement of fastener strip at the four corners formation is preferred, and for screens of 32 inches diameter or larger an arrangement of fastener strip at six locations (at the four corners and additionally at the two centres of the vertical or the horizontal screen edges) is preferable .

The object 16 can be of any size provided it fits within the area of the panel 10.

For attachment of an object such as a display monitor a minimum overhang of the static cling film relative to the fastener strip of 75 mm is suitable (and especially across the top border); the static cling film may extend beyond the fastener strip in any direction, most advantageously above the fastener strip Although 75 mm of overhang is preferred other values are possible (for example more than 5 or 10 or 25 or 50 mm, and/or less than 250 or 100 mm). The overhang may depend on the thickness of the object: for a relatively thin object such as a display monitor 75 mm may be suitable, whereas for a thicker object a larger overhang may be appropriate.

In an example, approximately 1 .5 kg of static load per 10 cm² of fastener strip can be safely attached. For a 19" display monitor, a 40 cm by 30 cm rectangular frame of fastener strip of 2.5 cm width may be placed around the edge of the monitor, and this might be able typically to support a load of up to 52.5 kg. For a 19" display monitor weighing 4 kg a 10.7 cm length of fastener strip with 2.5 cm width (27 cm²) is sufficient for attachment. Typically the weight load of the static cling film (in particular for a given minimum surface area corresponding to the object area) is greater than the fastener strip (in particular for an arrangement minimally affecting the appearance, without excessive fastener strip which may be visible), so the fastener strip needs to be selected with care.

The attachment is particularly useful for attachment to a window or similarly transparent panel, as it permits the object to be viewed through the panel, for example in a shop display. With the attachment shown in Figure 1 the object can be protected and effectively displayed at the same time. At the same time the attachment does not damage the window, nor does the attachment obstruct the window or reduce visibility of other objects in the window or mar the appearance by unsightly brackets or the like. By printing on the static cling film the display can be further enhanced.

Figure 2 shows an example embodiment of a sheet of film 18 arranged to be attached to a panel (not shown) without adhesive, such as static cling film, for example. A surface of the film 18 that is not to be attached to a panel has printed on it a decorative pattern 20 (or "surface decoration"). A region 22 of the surface decoration 20 is devoid of print (in other words, it has not been printed on). This unprinted region provides an aperture 22 through which an object on the other side of the film 18 (or a panel to which it is attached) may be viewed.

Similarly, Figure 3 shows another example of a sheet of film 19 having printed on it a surface decoration 21 . However, the sheet of film 19 in Figure 3 features four apertures 24-1 , 24-2. 24-3, 24-4 formed by leaving four discrete regions 24 of the surface decoration 21 unprinted.

As with the example described with reference to Figure 1 , a display monitor, such as an LED or LCD video panel (or screen), may be viewed through the film. The aperture(s) provided in the sheet of film are therefore dimensioned to correspond to the dimensions of a display monitor, such that a display monitor may be positioned within the aperture(s). Accordingly, the dimensions of an aperture may be, roughly, 385 mm x 220 mm for a 445 mm (17.5 inch) display monitor; roughly 700 mm x 400 mm for a 813 mm (32 inch) display monitor; or roughly 975 mm x 575 mm for a 1067 mm (42 inch) monitor, for example. As shown in Figure 2, a sheet of film 18 may have a single aperture 22 configured for either a 813 mm (32 inch) or a 1067 mm (42 inch) display monitor, for example. Alternatively, as shown in Figure 3, a sheet of film 19 may have four apertures 24-1 , 24-2, 24-3, 24-4 configured to display four 445 mm (17.5 inch) display monitors, for example.

The surface decoration (or pattern) may be printed onto the film using 'white ink technology', wherein a first under-layer of white ink is printed onto the film before the desired surface decoration is printed. This dual layer of printed ink provides the film with increased rigidity and hence structural strength. Preferably, the surface decoration is printed during a single print event, or in other words the surface decoration is printed as one single film sheet or poster.

Figure 4 shows a front side view of a film 18 having a surface decoration 20 with a region 22 that is devoid of surface decoration (or printing). A single aperture 22 is thereby provided in the film 18 generally centrally in a horizontal aspect, and spaced towards the bottom of the film 18, i.e. asymmetrically. The film 18 is attached to a smooth panel 100, which is preferably a sheet of smooth glass, such as a shop window, or similar, where the poster might be displayed. In the front view of Figure 4, the film 18 is attached to the far side of the panel 100, such that the panel 100 is in the foreground. A display monitor 90 mounted on the reverse side of the film 18 is visible through the aperture 22.

Figure 5 shows a reverse side of the film 18. A back plate 26 is attached to this reverse side of the film 18 via a fastener (not shown) which is located in a recess 28. The fastener recess 28 is spaced from the cavity 30. The recess 28 is arranged to be above the cavity 30 (and hence aperture 22) when the back plate 26 is attached to the panel 100 (via the film 18), such that the fastener supports the weight of the back plate 26. Suitable fasteners are described further on herein. The fastener is, ideally, in the form of an elongate, or strip fastener. A corresponding fastener (not shown) is also provided in a suitable position on the printed film 18. The fastener is, preferably, attached to the film 18 and back plate 26 using an adhesive that provides a stronger adhesion than that of the fastener itself so that the back plate 26 can be releasably fastened to the film 18 (and hence panel 100) without the fastener detaching from the film 18 or back plate 26 and/or damaging the print on the film 18.

In addition, the recess 28 for the fastener strip provides the advantage that it inhibits any slippage of the fastener strip down the back plate 26, and therefore provides additional attachment strength to the arrangement. The fastener may be provided as a single elongate strip, as mentioned, or as several individual (maybe shorter) elements, which may be rectangular, for example. The back plate 26 has a cavity 30 into which the display monitor 90 is received. The cavity 30 is spaced from the edges of the back plate 26, which edges provide a surrounding region of back plate 26. The surrounding region provides a surface for the fastener to be attached, preferably within a recess 28, as described above. Ideally, the cavity 30 is dimensioned such that the outward facing screen of the display monitor 90 mounted within it is substantially flush with the back plate 26 surround such that, when the back plate 26 is attached to the panel 100 (via the film 18), the screen of the display monitor 90 is adjacent the panel 100.

As shown in Figures 5 and 6, the back plate 26 has a main cavity 30, in which the monitor (not shown) is received. The main cavity 30 has three regions of different depths, as follows.

A first region 32 is shaped to receive the display monitor 90, and is generally rectangular in shape. The first region 32 ideally has substantially the same depth as the display monitor 90, such that a received monitor is flush with the back plate surround, as mentioned above.

A second region 34, having a smaller footprint than the first region 32, extends beneath the first region 32 to provide an air gap between a display monitor and the back plate, for cooling purposes. The air gap is, ideally, around 10 mm, to ensure that the overall back plate remains as thin as possible while providing sufficient heat dissipation. The second cavity portion 34 has a smaller footprint at least in part due to it having formations 36 arranged to support a monitor. Here, the formations 36 are chamfered corners in the second region 34, which support a monitor and maintain the desired air gap.

While chamfered corner formations 36 are preferred, other formations that reduce the footprint of the second region 34, relative to the first region 32, could be employed.

A third region 38 is provided beneath the second region at the base of the main cavity 30. The third region 38 is also provided towards the bottom of the back plate 26 - in a vertical sense, when the back plate 26 is fastened to a panel, in use. In this third region 38, to the base of the back plate 26, is mounted electronic componentry (such as power supply, graphics card, cooling fans, etc.)_for operating a display monitor. By mounting the electronic componentry (not shown) to the back plate 26 in the third region 38, the electronic componentry is spaced apart (via the air gap provided by the second region 34) from the rear of a display monitor received in the first region 32. The air gap improves airflow and hence cooling through the back plate 26.

Display monitors having a relatively high luminance (cd/m2) (or Nit (nt)) - of around 1 ,000 to 1 ,500 cd/m2 compared to a typical display monitor having a luminance of about 450 cd/m2 - may be used with the invention, such that content displayed on the monitor may be visible in daylight. Such high levels of luminance may cause additional heat generation due to increased power demands, for example. Cooling is therefore an important consideration.

Two cooling vents 40 are provided on the back plate 26, with a cooling vent 40 being positioned on opposing sides of the third region 38 of the cavity 30. The vents 40 are arranged such that, in use, air can flow (or be drawn) upwards through the cavity 30 of the back plate 26. The vents 40 are therefore positioned near to where the electronic componentry is mounted, to allow air to flow, to aid cooling and heat dissipation from the back plate 26 during operation of a monitor mounted within. One or more cooling fans may also be provided in the back plate 26, preferably mounted to the back plate 26 in the third cavity 38, to draw air across the electronic componentry, and thereby improve cooling.

In addition, the position of the third cavity portion 38 being towards the bottom of the back plate 26 ensures that the weight distribution (of the electronic componentry, etc.) is also towards the bottom of the back plate 26, to reduce a cantilever effect occurring that might pull the top of the base away from the film, in use. An Operating status' LED (not shown) may be provided inside the back plate 26 such that it is visible though one of the vents 40, to provide a discrete indication of the operating status of the monitor.

Figure 7 shows another embodiment, wherein a film 19 has been decoratively printed to provide a surface decoration 21 having four regions that are devoid of print to form four apertures 24-1 , 24-2, 24-3, 24-4. A different display monitor 92, 94, 96, 98 may be viewed through each aperture 24-1 , 24-2, 24-3, 24-4.

Figure 8 shows a back plate 44 for the (multiple) display monitors 92, 94, 96, 98. The back plate 44 is arranged to provide a cavity 46-1 , 46-2, 46-3, 46-4 for each of the four display monitors 92, 94, 96, 98, each cavity being spaced from the edge of the back plate 44. A further, deeper cavity 50 in which the electronic componentry for each of the display monitors 92, 94, 96, 98 can be mounted to the back plate 44 is provided generally centrally across the back plate 44, between the two upper 46-1 , 46-3 and two lower 46-2, 46-4 first cavity portions 46.

Similar to the embodiment shown in Figures 5 and 6, the back plate 44 has at least one separate recess 52 provided along the top of the back plate 44 for retaining a fastener (not shown) for securing the back plate 44 to a panel 100 via a film 19.

With the exception of the additional display monitors, the embodiment of Figures 7 and 8 shares most of the features of the embodiment of Figures 4 to 6. In particular, the asymmetrical positioning of the back plate 44 and apertures relative to the film 19, and the separate fastener recesses 52. Cooling vents (not shown) may also be provided.

Ideally, content to be displayed by a display monitor 90 may be provided by a removable memory, such as a 'USB memory stick' (i.e. a local memory source) connected to the electronic componentry in the back plate 26 via a suitable data port (not shown) such as a USB port, or similar. If so, the only wired connection to the display monitor 90 may be a power cable 42 to provide power to the display monitor 90 and associated componentry contained within the back plate 26. Such content may be described as 'local content', which can be changed by replacing, or updating the content on, the memory stick.

Similar to the single-screen embodiment of Figures 4 to 6, each display monitor of the multi-screen 92, 94, 96, 98 embodiment of Figures 7 and 8 may be controlled locally by a USB memory stick 48, or similar memory storage device.

Alternatively, display content may be centrally controlled, via the internet, for example, such that a user may change content across multiple display monitors simultaneously, or at least without having to be in physical locality of a display monitor. Accordingly, the componentry for a display monitor may also include means for establishing a, preferably wireless, network or internet connection, such as a wireless network card and dongle arrangement.

In another embodiment, content provided a display monitor may be arranged to be interacted with by a viewer. For example, a viewer may be able to control displayed content using a smart phone, or similar hand-held device. Control may be achieved via an 'App' or by registering a device with the content provided. A display monitor may further comprise suitable componentry to enable it to provide a captive portal providing digital services over a webserver.

While it is preferred to mount the display monitor to a panel using a back plate, it is of course possible to attach the display monitor directly to the panel via the film using fasteners attached directly to the display monitor, as previously described with reference to Figure 1 . Furthermore, while it is not essential for the film to have printed on it a decorative pattern, when used with a display monitor it is preferable to obscure the back plate and fastener with a decorative pattern to provide an aesthetically pleasing display poster, for example.

Two examples of possible applications are as follows:

The display monitor might be displayed in the window of a realtor or estate agent. Content displayed on the display monitor may therefore relate to real estate for sale. A person viewing the display monitor may be able to interact with the software and peruse the properties for sale.

- The display monitor and surrounding surface decoration may relate to a new movie. A person may be able to control the display monitor to display a trailer for the movie.

The above two examples are of course only two possibilities and by no means provide an exhaustive list.

The specific properties of a static cling film 12 and a fastener strip 14 are now described in more detail. It should be understood however that the examples provided below are only of preferred materials.

An example of a suitable static cling film that can provide high visibility and strength (especially tear strength) whilst being sufficiently flexible is Spandex™ clear polyvinyl chloride) (vinyl, PVC) static cling film (Spandex™ product number IP 2908). Such a static cling film adheres to surfaces without the need of an adhesive and is reusable. The static cling film is, ideally, a printable inkjet PVC film that sticks / clings to smooth gloss surfaces such as glass, smooth plastic and glossy metal surfaces. The static cling film sticks to these surfaces (such as windows or doors) without any adhesive and can be removed without leaving any residue behind.

A suitable static cling film thickness is 180 μηι, desirably between 50 and 500 μηι. Such a static cling film typically performs best in a temperature range of -30 °C to 70 °C. The film can be printed on, as mentioned above, for example to display a decorative border around the object. The film can be contour cut for a decorative effect. If the film is printed on, the printed graphic is applied such that the ink is not in direct contact with the window to avoid transfer of ink onto the window.

3M Dual Lock™ reclosable fastener is an example of a touch fastener strip 14 that can provide high strength (including 3M Dual Lock™ product numbers SJ3440, SJ3441 , SJ3442, SJ3540, SJ3541 , SJ3542, SJ3550, SJ3551 , SJ3552, SJ3560, of which SJ3551 - and SJ3552 to a somewhat lesser extent - have been found particularly appropriate). Product number SJ3550 is a preferred fastener. A suitable fastener strip has mushroom-shaped stems that interlock with one another when pressed together. A fastener strip is for example 25 mm wide. A fastener strip may also be for example 1 cm wide. The fastener strip may also be provided in the form of shapes such as circular. The fastener strip can be clear or opaque, for example black. Such fastener strips can be opened and reclosed over 1000 times.

A fastener strip can be attached to two opposing surfaces (rigid or flexible) by an adhesive, by staples, by sewing, by screw attachment, by riveting, by interlocking clips, by cable ties or similar tie strips, or by other means. A fastener strip can include apertures so that the fastener strip can be attached by screw fixing to the objects, in addition to or independently of other attachment means. Pressure sensitive adhesive is a particularly convenient means of attachment, for example with rubber or acrylic self-adhesive backing on the strip. Pressure sensitive rubber adhesive can bond to most surfaces. Pressure sensitive acrylic adhesive (such as 3M very high bond VHB™ adhesives) can provide high performance and resist harsh wet/dry, hot/cold cycles. Clear pressure sensitive acrylic adhesive can be UV resistant and plasticiser resistant. The range of suitable operating temperatures for fastener strips with pressure sensitive adhesives is in one example from -20 °F to 158°F (-29 to 70 °C) and can permit intermittent operation in the range of 158°F to 200°F (70°C to 93°C). For a stronger connection between the fastener strip and an object screw attachment (conveniently using disc-shaped fastener strip portions with a central aperture for insertion of a screw) can be chosen. Dynamic performance of a suitable fastener strip is in an example:

• Tensile disengagement for attachment of rigid to rigid surface: 207 to 380 kPa.

· Peel strength of rigid to flexible surface: 140 to 175 N.100mm.

The stem type of the fastener strip affects the dynamic performance.

Static performance of a suitable fastener strip is in an example:

• Static shear: fastener strip holds 500 to 1000 g/in² (77.5-155 g/cm²) for 7 days

• Static tensile: fastener strip holds 500 to 1000 g/in² (77.5-155 g/cm²) for 7 days

The stem types and operating temperature of the fastener strip affect the static performance. The static performance of the adhesive bond between the surface and the fastener strip is comparable to the static performance of the interlocking stems of the fastener strip.

The fastener strip in an example has a thickness (when engaged) of 3.8 to 5.8 mm and weighs from 0.5 to 1 .1 g for a fastener strip area of 25 mm x 25 mm. In an example, approximately 4 in² (25.8 cm²) of fastening strip area per pound (0.454 kg) of static load are suitable (0.176 kg of static load per 10 cm² of fastener strip).

The attachment of a fastener strip to two opposing surfaces (rigid or flexible) by staples, sewing, or riveting can for example allow bonding of the fastening strip to: polypropylene, plasticised vinyl, fabrics, leather, and rubber.

The attachment of a fastener strip to two opposing surfaces (rigid or flexible) by a pressure sensitive rubber adhesive can for example allow bonding of the fastening strip to: bare metal, painted metal, finished wood, paper, cardboard, glass, painted concrete, and plastics including polystyrene, acrylic, polyethylene, polypropylene polycarbonate and rigid vinyl. Pressure sensitive acrylic adhesive can, in addition to the above, allow bonding of the fastening strip to further plastics including plasticised vinyl. Pressure sensitive acrylic adhesive may however be unsuitable for polyethylene and polypropylene. For a good bond of the pressure sensitive adhesive it is conventionally applied at a temperature of 20 °C or above to a surface that is clean, dry and free from oil. 48 to 72 hours after application maximum bond strength is achieved. Improved resistance to edge peeling can be provided by recessing the fastener, or by rounding the corners of the fastener strip. Bond performance can in some cases (e.g. where the surface has a residue of a mould release film, or for rough or porous surfaces) be optimised by sanding or abrading the surface, or by using an adhesive primer.

Next, two procedures of mounting and dismounting an object (such as a display monitor) to/from a window are described:

Procedure 1

-To mount the object to a window:

1 . Clean the window

2. Wet the window surface

3. Apply the static cling film to the window by hand

4. Wipe bubbles between the static cling film and the window toward the edge of the static cling film, moving from the centre outwards and optionally with the assistance of a straight plastic wiping blade

5. Attach a first fastener strip part to the cling film by the pressure sensitive adhesive on the back of the strip part

6. Attach a second fastener strip part to a corresponding position on the object 7. Attach the two fastener strips parts to one another so as to mount the object to the window and apply pressure to ensure a stable connection of the fastener strip parts

-To dismount the object from a window:

1 . Peel back the static cling film starting at the corners until all static cling film overhanging the object is detached

2. Firmly grip the object and pull away from the window, such that the remaining static cling film detaches from the window

3. Peel the static cling film away from the object so as to detach the fastener strip parts from one another Procedure 2

-To mount the object:

This procedure is similar to Procedure 1 , with the difference that the fastener is first adhered to the object, with the film fastener fastened to the object fastener. The object is then mounted directly to the film with the adhesive on the film fastener exposed such that the adhesive adheres to the film, thereby ensuring that the fasteners are aligned correctly. -To dismount the object:

Again, similar to Procedure 1 , with the difference that the object is simply pulled away from the window, such that the fastener disengages leaving the film fastener attached to the window. The advantage here is that it is very simply to reattach the object to the window, assured that it is correctly orientated.

The attachment of an object to a vertical panel as described above can provide the following advantages:

• Enables connection of a product to a window

• Fast and easy to mount, dismount and remount

No mess - the object can be removed completely, without damage to or residue on the panel

The components individually are cheap and abundant

As a variety of suitable components are readily available, the system can be adapted within a wide scope

The attachment can hold significant weight

The attachment is not limited to vertical panels but can be used for panels overhanging beyond vertical, whether forward or backward, for example in tilting windows or overhead displays.

All of the components can be re-used

Enables energy efficient products, such as LED panels (that can reduce energy requirement/consumption), to be used

Long-term attachment is provided, up to a year or two years or more

The attachment is suitable for a wide range of panels (plastic, glass, and other) and objects (video display monitor, display cabinet, shelf, lighting) The duration for which the static cling film and fastener strip can maintain attachment of an object to a panel depends to some extent on factors such as the location of use and the environmental conditions, the frequency of use and the condition of the static cling film and fastener strip. For example a static cling film that has been attached and dismounted a number of times may have reduced loadbearing capacity due to accumulated residue on the surface or damage to the cling film (e.g. creases, deformations or holes).

In an alternative, the transparency of the cling film is such that the object is not adequately visible through the film. In this case, an aperture is arranged in the central portion of the cling film to enable display of the object, as described herein, with reference to Figures 4 to 8. In this case the necessary area of cling film for attachment can be maintained by providing a larger overhang of cling film around the object.

Other types of fastening strip can be used, such as hook-and-loop touch fasteners (though the described mushroom-type fastening strip is preferred as it may generally be more robust given weights and weight distribution of objects). Where the object is a digital display monitor, data to be displayed can be provided remotely by a wireless connection or by a physical connection such as a wire connecting to the screen. Power for the monitor can be provided by a physical connection such as a wire, or by other means such as a solar panel forming part of the monitor.

Where the object itself has a flat surface (such as the surface of a video monitor), or at least a surface that can conform closely to the surface of the smooth panel, then it may be possible to dispense with the fastening strips described above, and instead attach the object directly to the cling film.

In an alternative arrangement for attaching an object to a smooth panel a stiff laminate 'frame' is attached to the panel and the object is attached to the frame. The frame has an aperture sized such that the object is visible through the aperture. The frame extending around the aperture is large enough to bear the weight of the object and resist detachment of the frame from the panel. Suitable attachment of the frame to the panel, and of the frame to the object, are in particular pressure sensitive adhesives. This type of arrangement for attaching an object to a panel is particularly suitable if removal and repositioning of the object is not desired, and only a single mounting of an object once to a panel is desired. Suitable materials for the stiff frame include Foamx and MDF board. These provide the advantages of being lightweight to ensure the frame remains attached to the panel, yet strong enough to support the object. In a variant the frame has more than one aperture for displaying more than one object. Such a frame may be very similar to the 'back plate' described herein, with reference to Figures 4 to 8.

It will be appreciated that static cling film may be substituted with another material that can provide a film that is attachable to a smooth panel (without requiring adhesive) according to the arrangement of the present invention.

For example, another suitable arrangement for attaching an object to a smooth panel may comprise a film utilising micro-suction technology, wherein a film having thousands of microscopic craters (per unit area) on its surface, each functioning as a microscopic suction cup, may be provided as a direct substitute for static cling film described herein. Such a film may comprise polypropylene (PP), for example, which may offer certain advantages over PVC-based materials.

It will be understood that the present invention has been described above purely by way of example, and modifications of detail can be made within the scope of the invention.

Each feature disclosed in the description, and (where appropriate) the claims and drawings may be provided independently or in any appropriate combination.

Reference numerals appearing in the claims are by way of illustration only and shall have no limiting effect on the scope of the claims.
