This application claims priority to European Patent Application No. 23382443.2, filed May 12, 2023, and all the benefits accruing therefrom under 35 U.S.C. § 119, the contents of which in its entirety are herein incorporated by reference.
This disclosure relates to a protector for an elevator car. In particular, the disclosure may be applicable to a protector for an elevator car wall, such as for example a kickplate.
Elevator car walls, in particular the internal walls of an elevator car, are susceptible to damage during use of the elevator car. This could for example be caused by passengers leaning against or kicking the elevator car walls, or by impact from other items such as cargo being transported in the elevator car. Should the elevator car wall need repairing or replacing, a temporary shutdown of the elevator system and/or removal of the elevator car for maintenance would be needed. Elevator shutdowns are inconvenient for passengers and building managers and therefore should be avoided. There is therefore a need for protectors to be placed on the elevator car walls to protect the walls from damage.
Protectors known in the art may be attached to the wall using attachment mechanisms such as screws and bolts, or adhesives. These attachment mechanisms not only potentially mark or damage the elevator car wall, but they also take significant time to install and remove should the protector need to be replaced or moved. Because of the significant installation and removal time, more time will be spent when maintenance personnel wish to access the elevator car wall behind the protector, access the face of the protector which faces the elevator car wall, or move the protector to a different location on the elevator car wall.
The present disclosure seeks to address at least some of the drawbacks described above.
According to a first aspect of the disclosure, there is provided a protector for an elevator car. The protector comprises a protective panel; and one or more magnets mounted to the protective panel. The one or more magnets are configured to be attracted to an internal wall of a passenger compartment of an elevator car so as to retain the protective panel against the internal wall.
It will be understood that the protector according to the disclosure uses one or more magnets to retain the protective panel against the internal wall. This may provide a quick and straightforward means of attaching a protective panel to an internal wall of a passenger compartment of an elevator car. This may also allow the protective panel to be attached or fixed to the internal wall without the need to use fixing means such as screws or adhesives which would typically mark or damage the wall.
The one or more magnets could be mounted directly on the protective panel. In any example of the disclosure however, the protector may further comprise a support for mounting at least one of the one or more magnets to the protective panel. The support may space the at least one of the one or more magnets from the protective panel. This may allow the protective panel to be attached to the internal wall whilst also being spaced therefrom.
In some examples, the one or more magnets could be held against the support by magnetic attraction. In some examples however, it may be useful to provide means for holding the one or more magnets on or against the support. In any example of the disclosure, the protector may further comprise a retainer assembly which retains at least one of the one or more magnets against the support.
The retainer assembly could take many different forms. In any example of the disclosure, the retainer assembly may comprise first and second retainers extending outwardly from the protective panel. The first and second retainers may partially overlap the at least one of the one or more magnets such that the at least one of the one or more magnets is retained against the support.
In any example of the disclosure, the first and second retainers may each comprise a retainer bracket and a retainer lip. The first and second retainer brackets may extend away from the protective panel, and the first and second retainer lips may be disposed at the distal ends of the first and second retainer brackets. The first and second retainer lips may extend over part of the at least one of the one or more magnets, such that the at least one of the one or more magnets is retained between the first and second retainer lips and the support.
In any example of the disclosure, in addition to the examples of the retainer assembly described above or as an alternative, the retainer assembly may comprise a fastener extending through at least a part of at least one of the one or more magnets to fix the at least one of the one or more magnets to the support.
It will be understood that the protector comprises a protective panel for protecting the internal wall against damage. The protector may also house one or more further components for use inside the elevator car. In any example of the disclosure therefore, the protector may further comprise a component which may comprise one or more of an electrical device, an air freshener, a sound system, one or more sensors and a conduit for a fluid.
The component could be mounted to the protector in many ways, for example by being attached directly to or suspended from the protective panel. In any example of the disclosure however, the component may be disposed on a component support extending away from the protective panel.
In any example of the disclosure, the component may comprise an electrical device comprising a lighting device configured to emit light into the passenger compartment of the elevator car.
In any example of the disclosure, when the component comprises the electrical device, an electrical cable for powering and/or providing a signal to the electrical device may be mounted in a gap defined by the protective panel and a cable support.
In any example of the disclosure, the protector may comprise a diffuser. The diffuser may comprise a light diffuser. The diffuser may be disposed between the component and the passenger compartment so as to diffuse an output from the component to the passenger compartment.
According to a further aspect of the disclosure, there is provided an elevator car comprising: a passenger compartment defined by a floor, one or more internal walls and a ceiling; and one or more protectors as disclosed in any of the embodiments above, wherein the protective panel of the or each protector is retained against an internal wall of the elevator car by the one or more magnets.
It will be understood that the one or more protectors could be positioned anywhere desired within the elevator car. In any example of the disclosure, the one or more protectors may extend along part or all of the one or more internal walls adjacent to or abutting the floor.
According to a yet further aspect of the disclosure, there is provided a method for attaching the protector of any previous example to an internal wall of an elevator car, the method comprising: installing the protector adjacent to the internal wall, wherein the protective panel is held against the internal wall by the one or more magnets.
The one or more magnets could be mounted to the protective panel in any desired way. In any example of the disclosure however, the method may further comprise sliding at least one of the one or more magnets into a space defined by the first and second retainer lips, the support pad, and the first and second retainer brackets of the retainer assembly described above.
The method may further comprise sliding at least one of the one or more magnets along a part or all of the length of the protector.
The method may further comprise sliding one or more further magnets along a part or all of the length of the protector such that the magnets are spaced along the length of the protector.
In other examples, or in addition to the above, the method may comprise inserting a fastener to extend through at least a part of at least one of the one or more magnets to fix the at least one of the one or more magnets to the support.
According to a yet further aspect of the disclosure, there is provided a method of removing the protector of any previous example from an internal wall of an elevator car, the method comprising: using a threaded screw mounted between the protector and the internal wall to push the protective panel away from the internal wall.
In any example, the method of removing the protector may comprise: forming a bore hole in the protective panel; and/or inserting a fastener into a bore hole in the protective panel and attaching the fastener to the protective panel.
In any example of the disclosure, the method may further comprise inserting a bolt through the fastener.
In any example of the disclosure, the method may further comprise: rotating the bolt so as to to pass the bolt through the fastener such that the bolt extends outwardly from the protective panel towards the internal wall and then comes into contact with the internal wall; and further rotating the bolt so as to continue to pass the bolt through the fastener such that the protective panel is pushed away from the internal wall by the bolt.
In any example of the disclosure, the method may further comprise manually removing the protector from the internal wall.
From a still further aspect of the disclosure, a method of replacing the protector as described in any of the examples above is also disclosed. The method comprises: pulling a first protector away from the internal wall of an elevator car, optionally by one of the example removal methods described above; and installing a second protector on the internal wall, the protective panel of the second protector being attached to the internal wall by the one or more magnets.
As seen in
In any example of the disclosure, the elevator car 102 also comprises one or more protectors 200 disposed along one or more of the internal walls 106 thereof. The protectors 200 are configured to protect the internal walls 106 from being damaged by passengers 111 and/or cargo (not shown) in the passenger compartment 104. The protectors 200 could be located at any suitable point on a wall, for example at a height suitable to protect the wall from passengers 111 leaning against it. In some examples, the protectors 200 may be disposed at or towards the bottom of the internal wall 106, adjacent to and either forming a small gap with the floor 110 or in contact with the floor 110 of the elevator car 102. Such protectors 200 can prevent damage that could for example be caused by passengers 111 kicking or leaning against the elevator car 102. The protectors 200 may also improve the aesthetic of the passenger compartment 104, improving user satisfaction.
In any example of the disclosure, the protector 200 comprises a protective panel 202 which comprises a first side 202a and a second side 202b, as seen for example in
In all examples of the disclosure, the protective panel 202 comprises a height h, a length l (as seen in
The protector 200 comprises one or more magnets 204 (as shown for example in
At least in some examples of the disclosure, the or each magnet 204 may produce a sufficiently strong magnetic field, which results in a sufficiently strong force of magnetic attraction between the magnets 204 and the internal wall 106 such that passengers are not likely to accidentally remove the protectors 200 from attachment with the internal wall 106. The magnets 204 may be sufficiently strong such that only motivated maintenance personnel may remove the protector 200 from attachment with the internal wall 106. The maintenance personnel may swiftly and easily remove the protector 200 without the need for any specialist tools, enabling them to gain access to the hidden part of the internal wall 106 and the protector 200 more quickly, and therefore to perform maintenance more quickly. Upon completion of the maintenance, the maintenance personnel may re-attach the protector 200 to the internal wall 106 if desired. The protector 200 may be attached and/or removed many times without damaging the protector 200 or the elevator car 102 and without reducing the strength of the attachment of the protector 200 to the internal wall 106. At least in some examples of the disclosure, the magnetic force of attraction between each magnet 204 and the internal wall 106 may be between 1N and 400N, optionally between 300N and 400N.
The manufacturing process to produce the magnets 204 may include a moulding-sintering process. The manufacturing process to produce the magnets 204 may also include subtractive manufacturing techniques such as machining, which may include lathe-turning, milling, cutting, boring, drilling and grinding. The magnets 204 comprise any suitable ferromagnetic material, for example the magnets 204 may comprise any of neodymium, samarium cobalt, alnico and ferrite.
In any example of the disclosure, the protector 200 may comprise a support 210 which mounts the magnet 204 to the protective panel 202. The support 210 may space the magnet 204 from the protective panel 202. The support 210 may be formed integrally with the protective panel 202 (for example, by extrusion as will be described further below) or may be attached to the protective panel 202. The support 210 may comprise a support pad 212 and one or more support brackets 214. In at least one example of the disclosure, two support brackets 214 may extend substantially perpendicularly outward from the first side 202a of the protective panel 202. The support brackets 214 may extend across the entire length l of the protective panel 202, and may be spaced from each other along the height h of the protective panel 202. The support brackets 214 may each extend by substantially the same distance from the protective panel 202, and the support pad 212 may be disposed at a distal end of the support brackets 214, extending between the support brackets 214, thereby connecting the support brackets 214. The support pad 212 may extend substantially parallel to the protective panel 202 and may be spaced from the protective panel 202.
In at least one example of the disclosure, for example when the protector 200 comprises a metal or magnetically attractive material, the magnet 204 may be mounted to the protector 200 by magnetic attraction of the magnet 204 to the support pad 212. In any example of the disclosure however, the magnet 204 may additionally or alternatively be retained against the support pad 212 by a retainer assembly 220. In some examples of the disclosure, the retainer assembly 220 may extend at least partially around the magnet 204 such that the magnet 204 is retained between the retainer assembly 220 and the support pad 212. The retainer assembly 220 may be formed integrally with the protective panel 202 (for example, by extrusion as will be described further below) or may be attached to the protective panel 202. The magnet 204 may comprise a mounting face 204m that contacts the support pad 212 when the magnet 204 is retained in the protector 200 by the retainer assembly 220. The magnet 204 may comprise an attachment face 204c, which at least in some examples is configured to face towards and contact the internal wall 106 when the protector 200 is attached to the internal wall 106. In at least one example, the height hm of the mounting face 204m may be equal to or larger than the height hs of the support pad 212. The midpoint (not shown) of the height hm of the magnet 204 may be placed into alignment with the midpoint (not shown) of the height hs of the support pad 212.
In alternative examples of the disclosure wherein the one or more magnets 204 are configured to retain the protective panel 202 against the internal wall 106 as described above, the attachment face 204c may be configured to face towards the internal wall 106 and retain the protective panel 202 against the wall without the attachment face 204c being in direct contact with the internal wall 106. In said alternative examples, the one or more magnets 204 may produce a magnetic force of attraction that is sufficiently strong such that the protective panel 202 is retained again the internal wall without the one or magnets 204 being in direct contact with the internal wall. In such examples the one or more magnets 204 may be spaced from the internal wall 106 by a part of the protector 200, by a part of the internal wall 106, or by a component that does not form part of the protector 200 or the internal wall 106.
In some examples of the disclosure and as shown for example in
In any example of the disclosure including the first and second retainers 222, 224, the first and second retainer lips 222b, 224b may be disposed at the distal ends of the first and second retainer brackets 222a, 224a respectively. In any example of the disclosure including the first and second retainers 222, 224, the first and second retainer lips 222b, 224b may extend toward each other. In at least one example of the disclosure, the first and second retainer lips 222b, 224b may extend substantially parallel to the protective panel 202. The first and second retainer lips 222b, 224b, the support pad 212 and the first and second retainer brackets 222a, 224a may at least partially define a space 206. In at least some examples of the disclosure, the magnet 204 or a portion thereof may be disposed in the space 206. In any example of the disclosure including retainers, the first and second retainer lips 222b, 224b may overlap with or extend over first and second mating faces 208a, 208b of the magnet 204, which are configured to face towards the internal wall 106, thereby retaining the magnet 204 in the space 206 against the support pad 212. The first and second retainer lips 222b, 224b may overlap with the first and second mating faces 208a, 208b such that a gap remains between the first and second retainer lips 222b, 224b and the first and second mating faces 208a, 208b of the magnet 204. In other examples, the first and second retainer lips 222b, 224b may overlap with and contact the first and second mating faces 208a, 208b.
In at least some examples of the disclosure, the first and second mating faces 208a, 208b of the magnet 204 may form shoulders disposed on the first and second notches 208, the first and second notches 208 extending from the magnet 204, parallel to the protective panel 202. The first and second notches 208 may have a depth less than that of the magnet 204 and may be placed anywhere along the depth of the magnet 204. However, in alternative examples of the disclosure, the notch 208 may have substantially the same depth as the magnet 204, and the first and second mating faces 208a, 208b of the magnet 204 may be flush with the attachment face 204c.
As shown in
In one example of the disclosure, the retainer assembly 220 can comprise both the first 222 and second retainers 224 and one or more fasteners 230. In another example, the retainer assembly 220 comprises only the first 222 and second retainers 224. In a yet further example, the retainer assembly 220 comprises only the fastener 230.
In any example of the disclosure, the protector 200 may further comprise a component which may include one or more of an electrical device, an air freshener, a sound system, one or more sensors, and a conduit for a fluid. In some examples, the conduit for a fluid could be for hydraulic or pneumatic fluid for use in hydraulic or pneumatic systems. In other examples, the conduit for a fluid could be for a fluid for use in air conditioning, heat exchangers or odour control for example. In the arrangement shown in the Figures, the component is shown as an electrical device which comprises a lighting device 240 as discussed further below. In any example, the electrical device may receive power and/or be controlled via a wireless connection with a power source (not shown) and/or a controller (not shown). In any example, the electrical device may receive power via an electrical cable 250, also comprised within the protector 200. The electrical cable 250 may be configured to be connected to the power in the elevator car 102, for example it may be connected to an elevator car control panel (not shown). The electrical device may be configured to receive power from any power source, in one example the elevator car control panel (not shown), via the electrical cable 250. The electrical device may be configured to be controlled via signals such as electrical signals received via the electrical cable 250.
In any example of the disclosure, the electrical cable 250 may be mounted in a cable gap 258 defined by the protective panel 202 and a cable support 252. The cable support 252 may extend under the electrical cable 250 such that the electrical cable 250 rests on the cable support 252 and is supported by it. The cable support 252 may be formed integrally with the protective panel 202 (for example, by extrusion as will be described further below) or may be attached to the protective panel 202. The cable support 252 may comprise a first member 254 and a second member 256. The first member 254 may extend away from the protective panel 202, and the second member 256 may be disposed at a distal end of the first member 254 and extend away from the first member 254. In at least some examples of the disclosure, the first member 254 may extend substantially perpendicularly from the protective panel 202, and the second member 256 may extend substantially parallel with the protective panel 202. In at least some examples of the disclosure, the first member 254 may be configured to extend towards the internal wall 106 shown by dotted line 50. In alternative examples of the disclosure, the first member 254 may be configured to extend into the passenger compartment 104. The cable gap 258 may be defined by the protective panel 202, the first member 254, and the second member 256.
In examples of the disclosure, the electrical device may comprise any of an air freshener, a sound system or one or more sensors. In an alternative example of the disclosure, the electrical device may comprise a lighting device 240. The lighting device 240 may comprise one or more LEDs, for example in an LED strip, although any other electrical light source may be used. The lighting device 240 may be configured to emit light into the passenger compartment 104, providing further illumination and improving the aesthetic of the elevator compartment 104, thereby improving user experience.
The electrical device or any other component including but not limited to the alternatives described above (for example the lighting device 240) may be disposed on a component support 242 that extends away from the protective panel 202. The component support 242 may be formed integrally with the protective panel 202 (for example, by extrusion as will be described further below) or may be attached to the protective panel 202. The component support 242 may be configured to space the protective panel 202 from the internal wall 106. In some examples of the disclosure as seen in
In any example of the disclosure including a component, such as, for example, the electrical device, the component may be disposed on top of or underneath the component support 242. In other words, the component may be disposed on a first side of the component support 242 so as to face towards the floor 110 of the elevator car 102 when the protector 200 is installed on an internal wall 106 of the elevator car 102 or the component may be disposed on a second side of the component support 242 so as to face towards the ceiling 108 of the elevator car 102 when the protector 200 is installed on an internal wall 106 of the elevator car 102. In any of the examples of the disclosure, the component or electrical device may be attached to the component support 242 by any suitable means, for example with adhesive or fasteners such as screws or magnets (not shown).
In at least some examples of the disclosure, the protector 200 may comprise a diffuser. The diffuser may comprise any of a light diffuser, sound diffuser, scent diffuser or any other type of diffuser known in the art. When the diffuser comprises a light diffuser 260, the light diffuser 260 may scatter the light emitted from the lighting device 240 to create a visual effect. The visual effect may include, but is not limited to, reducing the brightness and/or making the emitted light softer. The light diffuser 260 may be translucent. The light diffuser 260 may be made of plastic. The light diffuser 260 may be disposed against the protective panel 202 of the protector 200. In any example of the disclosure, the spacer 288 and/or the light diffuser 260 may be configured to close a gap formed between the protective panel 202 and an internal wall 106 when the protector 200 is installed against the internal wall 106. The gap may be closed at an upper end of the protector 200 such that removal of the protector 200 by passengers or other unauthorised personnel is made more difficult.
The diffuser may be retained against the protective panel 202 by a diffuser retainer 262. In examples of the disclosure including a light diffuser 260, the diffuser retainer 262 and the light diffuser 260 may be disposed between the lighting device 240 and the passenger compartment 104 such that all of the light emitted from the lighting device 240 passes through the light diffuser 260 before entering the passenger compartment 104. In at least some examples where the light diffuser 260 is disposed on top of the component support 242, the diffuser retainer 262 may be disposed above the lighting device 240. In at least some examples where the light diffuser 260 is disposed below the component support 242, the diffuser retainer 262 may be disposed below the lighting device 240. The diffuser retainer 262 may be formed integrally with the protective panel 202 (for example, by extrusion as will be described further below) or may be attached to the protective panel 202.
In at least some of the examples of the disclosure, the diffuser retainer 262 may comprise a diffuser support 264 which extends from the first side 202a of the protective panel 202 (see
In at least some examples of the disclosure, the light diffuser 260 may comprise a diffuser slot 268. The diffuser slot 268 may have a shape similar to that of the diffuser retainer 262. The light diffuser 260 may be assembled onto the diffuser retainer 262 such that the diffuser retainer 262 is contained within the diffuser slot 268. In alternative examples, the light diffuser 260 may be disposed on top of, below, or on the side of the diffuser retainer 262 and may be attached to the diffuser retainer 262 by any suitable means, for example through the use of an adhesive or a fastener such as, but not limited to, a screw (not shown). In one example, the light diffuser 260 may be configured to be disposed between the protective panel 202 and the internal wall 106 shown by the dotted line 50. In another example, the light diffuser 260 may be configured to be disposed between the protective panel 202 and the passenger compartment 104. In any example of the disclosure wherein the diffuser comprises any of a sound diffuser, scent diffuser or any other type of diffuser, the diffuser may be attached to the protective panel 202 through the use of similar features to those described above.
In any of the examples above, the protector 200 may further comprise a foot 290 extending from the protective panel 202. The foot 290 may be configured to contact the floor 110 of the elevator car 102 when the protector 200 is attached to the internal wall 106 of the elevator car 102. The foot 290 may be formed integrally with the protective panel 202 (for example, by extrusion as will be described further below) or may be attached to the protective panel 202. The foot 290 may be configured to space the protective panel 202 from the internal wall 106.
In at least some examples of the disclosure, the protective panel 202 and/or some other parts of the protector 200, including but not limited to any combination of parts including the foot 290, the retainer assembly 220, the support 210, the cable support 252, the electrical support 242, the diffuser retainer 262 and the spacer 288 may be made of a metal, for example aluminium. In at least some examples of the disclosure, the protective panel 202 and/or any of the combination of parts listed above may be manufactured by extrusion. Alternatively, the protective panel 202 and/or any of the combination of parts listed above may comprise any other suitable material, for example another material capable of extrusion, such as a plastic or aluminium.
In at least some examples of the disclosure, the protective panel 202 and/or other parts of the protector 200, including but not limited to any combination of parts including the foot 290, the retainer assembly 220, the support 210, the cable support 252, the electrical support 242, the diffuser retainer 262 and the spacer 288 may be made of a non-magnetic material. By using a non-magnetic material for the protective panel 202 and/or other parts of the protector 200 described above, the force of magnetic attraction between the or each magnet 204 and the internal wall 106 of the elevator car 102 can be increased.
In at least some examples of the disclosure, the protective panel 202 may provide floor level protection or may be a kickplate.
A method for attaching the protector 200 of any of the examples above to an internal wall 106 of an elevator car 102 may include mounting one or more magnets 204 to the protective panel 202, wherein the magnets 204 are retained against the support 210 by a retainer assembly 220. The method further includes installing the protector 200 adjacent to the internal wall 106 such that magnetic attraction between the one or more magnets 204 and the internal wall 106 causes the protector 200 to be attached to the internal wall 106.
Mounting a magnet 204 to the protector 200 may comprise sliding the magnet 204 into the space 206 defined by the first and second retainer lips 222b, 224b, the support pad 212 and the first and second retainer brackets 222a, 224a. The method may further comprise sliding the one or more magnets 204 along a part or all of the length l of the protector 200, for example such that they are regularly spaced along the length l of the protector 200. In other examples, or in addition to the above, mounting a magnet 204 to the protector 200 may comprise inserting a fastener 230 to extend through at least a part of the magnet 204 to fix the magnet 204 to the support 210.
In at least some examples of the disclosure seen, for example, at
In at least some examples of the disclosure, the protector 200 may comprise a plurality of removal assemblies 300 disposed along the length or height of the protector 200. Alternatively, the protector 200 may comprise only one removal assembly 300. It will further be understood that the bore hole may be present in the protective panel at all times or it may be formed by maintenance personnel when they wish to remove a protector 200 from the elevator car 102.
A method for removing the protector 200 as described in any of the examples above is also disclosed. It will be understood that the method can be used in relation to any example of the protector 200 described previously. The method for removing the protector 200 may use the removal assembly 300 described above and may comprise: forming a bore hole in in the protective panel 202 if not already present; inserting a fastener 304 into a bore hole in the protective panel 202 and attaching the fastener 304 to the protective panel 202. The fastener 304 attached to the protective panel 202 is shown in
An alternative method for removing a protector 200 from a wall which may use an alternative removal assembly 300 is also provided. It will be understood that the alternative method can be used in relation to any example of the protector 200 described previously. The alternative method is illustrated in
The alternative method may comprise: attaching a fastener 304 to the internal wall 106 of the elevator car 102; inserting a bolt 302 into the fastener 304 such that the threads of the bolt 302 engage the threads of the fastener 304; forming a bore hole in the protective panel 202 if not already present; passing a tool through the bore hole and into engagement with the bolt 302; loosening the bolt 302 with the tool such that it moves in a direction normal to the internal wall 106 and such that a proximal end of the bolt 302, opposite the end received in the fastener 304, contacts the protective panel 202, wherein the plane head 306 is disposed at the proximal end of the bolt 302; continuing to loosen the bolt 302 such that the protector 200 is pushed away from the internal wall 106 in a direction N normal to the internal wall 106 to create a clearance gap (not shown) between the protector 200 and the internal wall 106; and manually removing the protector 200 from the internal wall 106. In at least some examples of the disclosure including the alternative method, the steps of attaching the fastener 304 to the internal wall 106; and inserting the bolt 302 into the fastener 304 such that the threads of the bolt 302 engage the threads of the fastener 304, may be performed before the protector 200 is attached to the internal wall 106.
A method for replacing the protector 200 as described in any of the examples above is also disclosed. The method comprises: pulling a first protector 200 away from the wall 106 of an elevator car 102 with a force greater than that exerted by the one or more magnets 204, optionally by one of the example removal methods described above; and installing a second protector 200 on the wall 106, the protective panel 202 of the second protector 200 being attached to the wall 106 by the one or more magnets 204.
It will be appreciated by those skilled in the art that the disclosure has been illustrated by describing one or more examples thereof, but is not limited to these examples; many variations and modifications are possible, within the scope of the accompanying claims.
