Title: LUMINESCENT DISPLAY DEVICE
Inventor(s): David A. TURK, Dean T. ANDREWS
Title: LUMINESCENT DISPLAY DEVICE
FIELD OF THE INVENTION
This invention relates to devices for displaying addresses and other identifying indicia, and more particularly, to house numbers which are visible in the dark.
BACKGROUND OF THE INVENTION
Most buildings have affixed to their exterior some means of identifying their address. This is typically done using one or more large numbers identifying the street number of the building, which can be seen by drivers or passers-by who may be looking for a building corresponding to a given street address. It is also common to find other identifying indicia on buildings, including the name of a commercial building or the names of tenants of a commercial building, a street name, or surnames of the residents of a house. Further, a combination of letters, numbers and symbols may appear on a sign constructed to be easily viewed by the public.
Currently, many house numbers are constructed of a shiny, non-corrosive, metallic alloy such as brass. These devices are relatively inexpensive, sturdy, weather-resistant and easily visible by drivers and passers-by in the daylight. Some house numbers are made of other materials, affixed to a backing typically of a contrasting colour, or may simply be painted onto a sign or wall. However, these prior art numbers are not very visible in the dark.
There exist various devices for identifying addresses of houses and buildings which are visible at night, including U.S. Patent No.
5,408,773 issued to Hwang on April 25, 1995, U.S. Patent No. 4,951,405 issued to Sabala on August 28, 1990, U.S. Patent No. 4,903,172 issued to Schoniger et al. on February 20, 1990, U.S. Patent No. 4,373,284 issued to Crane on February 15, 1983, U.S. Patent No. 4,272,901 issued to Matthews on June 16, 1981, U.S. Patent No. 4,254,257 issued to Lordier on March 3, 1981, U.S. Patent No. 4,009,535 issued to Stock on March 1, 1977, and U.S.
Patent No. 3,864,861 issued to Hill, Jr. on February 11, 1975. However, all of these devices require an electrical or photoelectric energy source to illuminate the identifying indicia or display unit. Most of these prior art devices contain many components which can make the movement or installation of the device cumbersome. These devices may also be bulky and boxy looking which may make their appearance unattractive.
The device of Whitehouse disclosed in United Kingdom Patent Application GB 2,250,636 is a building identification means made of a supporting substrate which surface is coated with a material that glows in the dark. However, while the glowing material may allow for greater visibility in the dark, this device is inferior to other devices made of brass with regards to durability, visibility in the daylight, and attractiveness.
There is accordingly a need for a device for displaying identifying indicia which is easily visible during the day and at night, which is durable and attractive, and which does not require an electrical energy source.
SUMMARY OF THE INVENTION
The invention provides for a device for displaying identifying indicia comprising a substrate shaped to resemble an alphanumeric character, the substrate having a top surface being made from a material visible in the presence of light, having a top surface and a top layer of luminescent material in the shape of the same character, with the top layer covering only a part of the top surface of the substrate thereby leaving the remainder of the top surface uncovered.
The top layer is preferably inlaid in the top surface of the substrate, which is preferably made of brass. The luminescent material is preferably a photoluminescent material which absorbs energy in the presence of light, and emits light in the dark.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
Figure 1 is a top plan view of a device for displaying the numeral "1" in accordance with the preferred embodiment of the present invention;
Figure 2 is a side elevational view of the device shown in Figure 1;
Figure 3 is a top plan view of a device for displaying the numeral "1" in accordance with an alternative embodiment of the present invention; and Figure 4 is a side elevational view of the device shown in Figure 3.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figures 1 and 2, illustrated therein is a device for displaying identifying indicia shown generally as 10, made in accordance with the preferred embodiment of the invention. Display device 10 comprises a substrate 12 which is shaped to resemble a specific identifier to be displayed, and a top layer of luminescent material 14. The term "luminescent material" as used herein, refers to materials capable of glowing in the dark, including photoluminescent and phosphorescent materials, which absorb energy in the presence of light and subsequently emit light in the dark.
As shown in Figure 1, substrate 12 comprises top surface 16 and side walls 18, which are shaped to resemble the number "1". Substrate 12 typically takes the shape of a single alphanumeric character, but it may also take the shape of a combination of two or more alphanumeric characters. Alphanumeric characters include upper case and lower case alphabetical characters, numbers, or symbols. The alphanumeric characters may taken on different shapes, sizes, fonts, and designs, and the numbers and symbols may have origins in languages other than English.
Substrate 12 is composed of a solid material visible in the presence of light, such as a coloured plastic, wood, metal or metallic alloy.
In the preferred embodiment of the present invention, substrate 12 is composed of brass. The dimensions of substrate 12 will vary depending on the application of the present invention. For example, if display device 10 were to be affixed to the exterior of a house, substrate 12 may have a height of about six inches, a width of about three inches, and a thickness of about one-half of an inch.
Substrate 12 may contain one or more bores 20 on the bottom surface which can be used to mount device 10 onto a wall or sign on which pegs, nails, screws or the like are embedded. The depth of bores 20 will vary, and will typically be one-half the thickness of substrate 12.
Alternatively, bores 20 may be constructed to extend through to the top surface of substrate 12. Other alternative means of mounting device 10 onto a wall or sign may be available.
Top layer of luminescent material 14 also resembles the shape of the specific identifier to be displayed. Top layer 14 is preferably inset from the side walls 18, and covers only a central portion of substrate 12 leaving the outer edges of top surface 16 of substrate 12 visible, thereby forming a border 22 which is an outline of the shape of the specific identifier to be displayed. Top layer 14 in the shape of the specific identifier to be displayed allows the identifier to be seen easily in the dark, while the visible border 22 of substrate 12 in the shape of the specific identifier allows the identifier to be easily recognized in daylight.
Preferably, top layer 14 is inlaid in groove 24 in top surface 16 of substrate 12, and has a thickness identical to the depth of groove 24, such that the top surface of layer 14 is flush with top surface 16 of substrate 12. This results in a device 10 having a level top surface.
Top layer 14 is preferably composed of a plastic embedded with a photoluminescent pigment such as ProGlow's Nightlight20 (Trade Mark) pigment powder, which is affixed to substrate 12 by a suitable adhesive. ProGlow's Nightlight20 pigment powder emits a light, yellowish-green colour in the dark, and may appear yellow or white in the daytime. ProGlow's Nightlight20 is said to glow for 20 hours at a minimum luminosity of 46 mcd/m2 after exposure to any light source for 10 minutes, and can reach a luminosity as high as 1794 mcd/m2 immediately after removal of the light source. Furthermore, such pigment powder withstands most chemicals and functions normally outdoors under severe environmental conditions, which make it suitable for use in the construction of the present invention. The plastic may be made with a resin such as DuPont's Surlyn~ ionomer resin, which produces a clear, durable plastic. Alternatively, top layer 14 may comprise a photoluminescent powder mixed in with a paint or other base to be applied directly, or indirectly through an intermediate substrate, onto substrate 12.
Referring now to Figures 3 and 4, shown therein is a device made in accordance with an alternative embodiment of the invention.
Device 30 comprises a substrate 32 and a top layer of luminescent material 34 both resembling a specific identifier to be displayed. Substrate 32 comprises a top surface 36 and side walls 38. In this embodiment of the 25 invention, top layer 34 covers a peripheral portion of substrate 32, leaving a central portion of top surface 36 of substrate 32 exposed. Top layer 34 forms an outline of the identifier to be displayed. Top layer 34 allows the identifier to be seen easily in the dark, while the exposed central portion of top surface 36 of the substrate 32 allows the identifier to be easily 30 recognized in daylight. Substrate 32 may contain one or more bores 40 on the bottom surface which can be used to mount the device onto a wall or sign. Top layer 34 is preferably inlaid in groove 44 in top surface 36 of substrate 32, such that top surface of layer 34 is flush with top surface 36 of substrate 32.
Display device 10 can be easily mounted onto the exterior of a building or on a sign. Device 10 is also durable and attractive, and is easily visible during the day and at night, and does not require an electrical energy source.
It should be apparent to those skilled in the art that while the layer of luminescent material is preferably inlaid in a groove in the top surface of the substrate mounted flush with the top surface of the substrate, the thickness of the top layer of luminescent material could be greater or less than the depth of the groove. Furthermore, the top layer may be applied to the top surface of the substrate using an adhesive.
Alternatively, the layer of photoluminescent material could be painted onto the top surface of substrate although this construction would not be as durable or attractive as the preferred embodiment.
It should therefore be understood that various modifications can be made to the preferred and alternative embodiments described herein without departing from the subject invention, the same of which is defined in the appended claims.
