Definitions

  • the current invention relates to the field of illuminated displays in general.
  • the invention relates specifically to a sign display assembly with an illuminated translucent or transparent panel, optionally containing information, that holds at least one removable back lit plate, optionally containing information, where said plate may be removed and replaced with itself, or with another plate containing different information, without causing damage to itself or to the said panel.
  • the one or more plates may be located on the illuminated panel in different places, according to the design requirements of the sign assembly.
  • Advertising and sign display systems have been known that use illumination to increase the visibility of the information displayed on the sign display panel.
  • This illumination may be front lit, back lit or edge lit according to the invention.
  • the information contained on the display panel, or poster contained thereon may be either: unchanging in nature, such as in shop fascias or permanent advertisements, or may require changing periodically as with advertising hoardings or billboards. Examples of these types of inventions can be seen in the following prior art:
  • the inventions generally specify a single plate and have limited scope for including additional plates or illuminated displays of information, indicia or graphics which may compliment the information contained on the plate.
  • the plaques contain information about the deceased which may be replaced with another if required.
  • the information contained on the plurality of plates can be changed or replaced readily. Furthermore the lighting to each individual plate may be turned on or off selectively, thus giving further meaning to the information. All the inventions facilitate the ready removal and replacement of the plates, however, the inventions specify that only the plates should be illuminated and there is limited scope for including additional illuminated display of information such as advertising, artwork or images which may compliment the information contained on the plates.
  • a sign assembly consisting of at least one removable back lit plate, optionally containing back lit information, held on an illuminated translucent or transparent panel, which may optionally contain information such as advertising material, artwork, characters, images, indicia or graphics, whereby the said plate may be removed and replaced with itself, or with another plate containing different information, without causing damage to itself or to the said panel.
  • the plate(s) may be held on the illuminated panel in different locations, according to the design requirements of the sign assembly.
  • the illumination may be natural or artificial light, or both, and arranged in such a way as to provide the back lighting for both panel and plate(s).
  • the aim of the current invention seeks to overcome the problems of prior art by combining the advantages of an eye catching and easy to read illuminated display panel, which may optionally contain information, with one or more removable back lit plates, or plaques, where the information contained thereon is not only more visible by way of the back lighting, but can also be changed readily by replacing the plate(s) with other(s) containing different information.
  • the invention provides a sign display system whereby part of the information display can be changed easily, whilst maintaining other parts unchanged.
  • the invention provides a sign display system whereby one or more plates, optionally containing information, may be accommodated in various locations on an illuminated panel which may also contain further information.
  • the invention provides a sign display system whereby the removable plate(s) and the supporting translucent panel are both back lit such that the information contained on said plate(s) and said panel are both illuminated and rendered more visible.
  • the light source may be natural light, as would be the case if the invention is located in a window opening, or situated in front of a window opening which has access to natural light.
  • the light source may be artificial light, whereby the invention would be located over a light box or situated in such a way that a source of artificial light can be directed to the back of the invention.
  • a further alternative may employ both natural and artificial light to provide the illumination. This said further alternative may be employed, for example, when a natural light source diminishes thus requiring artificial lighting to boost the illumination.
  • the front of the invention is defined as the side which is meant to be viewed by an observer.
  • the light source for the illumination is situated behind the plate(s) and the translucent, or transparent panel, which holds the said plate(s).
  • the illuminated translucent or transparent panel occupies a surface area significantly greater than that occupied by the plate(s) in order to increase the visual impact of said panel.
  • an objective of the current invention is to provide a high visual impact display which can be seen even in low light situations.
  • the advertising material, artwork or supporting information contained on the illuminated panel may either be permanent in nature, semi permanent, i.e. rarely changed or modified, or may not be included at all; i.e. the illuminated panel may be monochromatic or contain no information or decoration at all.
  • the back lit plate is held on the illuminated panel in such a way as it can be removed and replaced readily without damage to itself or to the said panel,
  • a further objective of the invention is to provide a sign display assembly containing back lit removable plate(s) whereby information contained thereon can be changed or replaced easily. Also, the plate(s) held on the illuminated background panel may remain blank, i.e. without containing information, until required otherwise by changing circumstances.
  • each individual plate may be illuminated selectively by turning on or off a corresponding light source situated immediately behind the said plate.
  • those skilled in the art would devise the illumination such that the light source for the illuminated panel and the individual plates can be distributed and controlled separately.
  • Fig. 1A shows an embodiment of the invention showing the general arrangement of the illuminated panel (2), plate(s) (1) and the sign assembly frame (3).
  • fictitious information depicted as the characters: 'MANAGEMENT STRUCTURE', ' Q Seven Industries and the artwork 'Q 7' is designated as the supporting information (4) which compliments the information (10) on the plate(s) (1).
  • the supporting information (4) is deemed to be permanent or semi-permanent in nature and is contained on the illuminated panel (2). Suggested means used to apply the supporting information (4) to the panel (2) are described below in paragraphs [0052] to [0057], though not to the exclusion of other means which achieve the desired results.
  • the information (10) contained on the plates (1) is deemed to be variable and can be changed by replacing the appropriate plate with another containing different information. Suggested means used to apply the information to the plates are described below in paragraph [0068] and paragraphs [0070] to [0072], though not to the exclusion of other means which achieve the desired results.
  • the illuminated panel (2) is held in a frame (3) whose proportions are not restricted by the specification of this invention but which broadly follow the shape and size of the said panel.
  • the frame (3) may be made from suitable materials such as, but not exclusively, wood, UPVC or plastic extrusions, aluminium extrusions or steel profiles and fabricated using the known methods as used by those skilled in the window frame or door making industry.
  • the said panel (2) may be held in a rebated portion of the frame as commonly adopted to fit glass panels into frames used in the window or door making industry. These may include, though not exclusively, battens, clips, adhesive mastic or special profile strips designed to clip onto the rebated section of a window frame extrusion.
  • join between the panel (2) and the frame (3) may be sealed to resist the elements by means (not illustrated) such as mastic, silicon sealants or flexible sealing strips.
  • the panel (2) may be made from any material which is translucent or transparent and fulfills the structural and constructional requirements of the sign display. Such materials may include, though not exclusively, glass, polymers, acrylic, fiberglass, resins, polycarbonates and plastics. In the preferred embodiment of the invention the preferred material is translucent acrylic sheet though other materials may be used such as those previously described.
  • the material used for panel (2) may be coloured, monochromatic, opalescent, translucent or transparent and may have one or all of its surfaces 'frosted', for example by sand blasting, to act as a diffuser to the light source (11).
  • a method is suggested whereby information may be displayed through, or in front of the panel (2) by the inclusion of a poster or advertising material which may be affixed either directly to the surface of the panel (2) or sandwiched between the panel (2) and a supplementary panel (not illustrated) adjacent to panel (2). It is desirable that the poster or advertising material should be sufficiently translucent to allow the passage of light so that it appears illuminated when subjected to a light source behind it.
  • a method is suggested whereby information may be applied to the surface of panel (2) by painting, printing or screen printing an opaque medium which may be further decorated when dry, set or hardened.
  • a further method is suggested whereby information may be applied to the surface of panel (2) by the application of self-adhesive lead strips which, when applied, may have the enclosed spaces they create decorated by the application of coloured translucent laminates.
  • Such methods are used to create a simulated visual effect similar in aspect to a stained glass window.
  • the panel (2) may also be made as an actual stained glass window constructed from individual glass pieces assembled with lead came using the methods know by those skilled in the arts.
  • the assembly of frame (3), panel (2) and plates(s) (1), as shown in this embodiment, may be located in a window opening, or in front of a window opening, whereby the illumination for the sign assembly comes from a light source (11) which may be natural light.
  • Optional artificial light sources (12), such a spot lights, may be used to supplement the natural light source when said natural light source fails or diminishes.
  • the frame (3) may be devised such that it is hinged to a fixed frame (not illustrated) to permit the frame & panel assembly (3 & 2) to be operate as an opening window.
  • Fig. 1B shows the plate (1), panel (2) and frame (3), in cross section, and shows the orientation of the invention where the front is defined as the side seen by the viewer (13).
  • the illumination (11) and/or (12) is directed at the opposite side to the viewer and provides the back lighting for both panel (2) and plate(s) (1).
  • Fig. 2A shows the preferred embodiment for representing information (10) on the plate (1) where the said information may be represented as characters, indicia, images or artwork.
  • the surface areas occupied by the information (10) are substantially translucent whilst the remaining surfaces of the plate are substantially opaque, or sufficiently less translucent than those of the information, so as to create a high contrast between said information and said plate.
  • Fig. 2B shows the preferred embodiment material made from a multi layered material composed of at least two layers; one layer (14) being substantially opaque and the other layer (15) being substantially translucent. In this embodiment the material is orientated so that the substantially opaque layer (14) is facing the viewer (13).
  • the plate material is a specialised multi layered plastic or acrylic composite material which is composed of the aforementioned substantially opaque and substantially translucent layers.
  • This preferred material is not exclusive and other materials may be used which achieve the desired results.
  • the information (10) may be formed by removing parts of the substantially opaque layer (14), using a laser, engraver or router cutter, to reveal below the substantially translucent substrate layer (15) in the form of the information shapes.
  • An alternative plate material may be composed of a translucent or transparent substrate (15), such as a glass, resin, polycarbonate, plastic or acrylic, with a substantially opaque layer (14) applied to it, such as a paint film or a laminate film.
  • a translucent or transparent substrate such as a glass, resin, polycarbonate, plastic or acrylic
  • a substantially opaque layer (14) applied to it, such as a paint film or a laminate film.
  • the information may be formed by applying the substantially opaque layer (14), as a paint or pigment film, directly to the substantially translucent substrate (15) leaving the unpainted areas to form the shapes of the information.
  • a mask in the form of the information shapes, may be applied first to the substrate layer (15) and then removed later after the substantially opaque paint or pigment layer has been applied and hardened.
  • a suggested method to apply the paint film is by paint spraying but this does not exclude other methods which achieve the desired results.
  • a laminate film made of a substantially opaque material, with the information shapes already cut out, may be applied to the substantially translucent substrate (15) leaving translucent areas visible in the form of the the information shapes.
  • Fig. 2C shows an alternative orientation of the plate (1) where the substantially translucent layer (15) is facing the viewer (13).
  • the information is formed in the substantially opaque layer (14), but with the shape of the information in reverse format, as a mirror image, so that the information can be read correctly when viewed as described.
  • Fig. 3A shows an alternative embodiment for representing information (10) on the plate (1) where the said information may be represented as characters, indicia, images or artwork.
  • the surface areas occupied by the information (10) are substantially opaque whilst the remaining surfaces of the plate are substantially translucent, or sufficiently less opaque than those of the information, so as to create a high contrast between said information and said plate.
  • Fig. 3B shows the alternative embodiment material made from a multi layered material composed of at least two layers; one layer (14) being substantially opaque and the other layer (15) being substantially translucent. In this embodiment the material is orientated so that the substantially opaque layer (14) is facing the viewer (13).

  • the information is formed by the substantially opaque layer (14), but with the shape of the information in reverse format, as a mirror image, so that the information can be read correctly when viewed as described.
  • Fig. 4 illustrates a preferred means of holding the plate (1) to the panel (2) such that the said plate may be removed without damage to itself or to the said panel.
  • the fastening method is at least one screw threaded bolt (5), coupled to a screw threaded nut (6), with said bolt passing through a proportionally sized hole through both plate (1) and panel (2) so that both components are held together when the said nut is screwed onto the threaded portion of bolt (5).
  • An alternative mechanical fastening may be the use of at least one clevis pin (not illustrated), instead of the bolt (5), similarly passing through a proportionally sized hole through both plate (1) and panel (2) and a split pin, or pin, (not illustrated), instead of a nut (6), to secure the clevis pin and components together.
  • Another alternative fastening may be the use of at least one magnet (not illustrated) to hold the plate (1) to the panel (2).
  • a magnet or magnets may be fixed to the panel (2) and a corresponding magnetisable plate, or plates, fixed to the plate (1) such that when the two are brought into contact with each other in the correct position, the plate (1) is thereby held by the said panel as a result of magnetism.
  • Alternative materials and/or alternative location of the magnet(s) may be employed which achieve the same objective of magnetically holding the plate (1) to the panel (2).
  • a further alternative method of holding the plate (1) to the panel (2) is by using a 'slide and groove' method (not illustrated) such that the plate (1) may be slidably located in position on the panel (2) in grooved retainers fixed to the same panel.
  • These grooved retainers may take the form of two flanges, spaced apart at an appropriate distance to accommodated the plate (1), and fixed to the panel (2), such that when the plate 1 is slid between the flanges, the said plate is held securely in place but can be slidably removed if required.
  • Designs of 'slide and groove' fixings already exist in prior art and suitable devices which achieve the objective may be adopted by those skilled in the arts.
  • a 'hook and eye' material such as the material with the trade name 'Velcro', to hold the plate (1) and panel (2) together.
