Application August 3, 1948, Serial No. 42,218
This invention relates in general to marker devices which are particularly adapted for use in marking the edges of passageways such as sidewalks, driveways, highways and the like.
Driveway and highway markers, as such, which utilize the customar reflecting elements are old in the art, but the present invention contemplates not only a novel form of mounting means for these reflector units, but also utilizes an area of a luminous substance in conjunction with said reflector units.
The primary object of the present invention is to provide a marker device of the character herein described which combines as a single unit a reflector element and an area of luminous material adjacent thereto, both of which are adapted t o be mounted on a suitable supporting member.
Another object of the invention is to provide a marker device wherein a supporting member has applied thereto, closely adjacent areas of light reflecting material and a luminous material.
A further object of the invention is to provide a marker device which has mounted thereon a plate or disc formed of a luminous material, and which plate or disc has mounted thereon one or more reflector elements. The luminous plate is of such a character as to absorb light during the day, or any other light which may be directed thereon, and to then emit the light thus absorbed at night. Also, the reflector units are such as to reflect any light which may be directed thereon at night, whereupon the markers may be seen by reason of the luminous material when no other light is present, and the reflector elements may be seen when light is directed thereon.
Still another object of the invention is to provide a novel form of mounting means for a reflector and luminous unit, wherein a supporting member is provided with a recess open at one side and at one end thereof. The luminous material is in the form of a plate or disc which is adapted to have one or more reflector units mounted thereon. The unit is then received within the recess of the supporting member and retained therein so that the entire device can be suitably located along the edges of sidewalks, driveways, and the like.
Other objects and advantages of the invention will become apparent upon reading the following description taken in conjunction with the accompanying drawing in which:

Fig. 8 is an enlarged fragmentary vertical sectional view along the lines 8---8 of Fig. '7.
Briefly described, the invention involves the use of one or more reflecting discs and adjacent to which are areas formed of a luminous material. The luminous substance is preferably formed of a solid sheet or plate of material, and may either be adapted to support one or more of the reflector units thereon, or the reflector unit may be a sep-- arate and dist nct element from the areas of luminous material. In one form of the invention the luminous member has openings therein, adapted to receive and mount a plurality of reflector elements. In another form of the invention, the reflector unit is mounted by itself, and portions of a luminous material are mounted closely adjacent thereto. The resulting object in either case will be the same. Also, in another form of the invention, the luminous disc and reflector elements may be so mounted on a supporting member as to face in two directions opposite to each other on opposite sides of the supporting member, all as will be more clearly pointed out hereinafter.
Referring now more particularly to the drawing, and especially to the form of the invention shown in Figs. 2, 3, and 4, the supporting member is generally indicated by the numeral I, and may, if desired, have the lower end thereof tapered to form a point, as at 2, so that the entire device may be easily placed in the ground adjacent sidewalks, driveways, and the like.
In this form of the invention, both sides of the supporting member l are provided with recesses which may be indicated by the numerals 3 and 4. Actually, these recesses constitute an opening entirely through the supporting member with an enlarged portion intermediate the two sides of the member, as shown at 5. This enlargement of the recess thereby provides inwardly extending flanges 6 and 1 at one side of the support, and flanges 8 and 9 on the opposite side of the support. The units formed by the reflectors and luminous substance are adapted to be received within the enlarged part of the recess, and will thereby be held in place against lateral movement by means of the flanges 6, l, 8 and 9.
Both units in this form of the invention are preferably identical, and are indicated generally by the numeral ill. Each unit consists of an elongated plate 5 l formed of a luminous material which is capable of absorbing light and then emitting the light at night so it may be seen in the dark. Each plate H has a plurality of openings 12 therein, and the number of these openings is not an important consideration. For purposes of illustration, three such openings have been shown. The reflector element it may be of any conventional and commercially available type of light reflecting material. This element usually consists of a reflecting surface It and an annular flange it around the base thereof. Each reflector element i3 is adapted to be received in one of the openings l2 of the luminous plate H. A recess is provided around each opening H at one side of the disc 52 which may receive the annular flange !5, as more clearly seen in Figs. 3 and 4. This will enable the reflecting part of the element is to extend into and through each of the openings 2, whereby the back or base of the reflector unit will be flush with the inner surface of the lmninous plate H.
The upper end of the recess in the supporting member is normally left open so that two of the units can be placed back to back, and inserted into the recess through the open upper end thereof. After the units are in place in back to back relation, a suitable block or plug H5 may be inserted to close the open upper end of the recess. Suitable means can be used, if desired, to permanently secure the plug it in place so that it may not be easily removed.
The entire device thus provided permits the luminous portion and reflector portions of the marker to be seen from both sides; thus if a number of the markers are placed along the sides of the driveway, they can be seen from either side thereof, and will locate the edges of the driveway at night. The flanges provided on opposite sides of each of the recesses are utilized to retain the units in place therein, and prevent removal thereof.
Figs. 5 and 6 illustrate a modified form of the invention, wherein only one of the units may be used, so that the luminous and reflecting portions thereof maybe seen from only one side of the supporting member. In this case, the support may be indicated by the numeral ii, and will have a recess iii open at one side thereof and at its upper end. The inner part of the recess [8 is enlarged as at E9, thereby providing the retaining flanges 2B and 2!. The unit, consisting of the luminous plate and reflector elements, may be of the same form as that described above, and may include the plate ll and reflectors IS. The unit may be inserted into the recess [3 from the open upper end thereof in the manner described above, and such open upper end may be either temporarily or permanently closed by means of a suitable plug similar to the plug 56. The two forms of the invention are similar, except that in the one case, the units may be seen from both sides of the support, and in the other case the units may be seen from only one side of the supr -v Still another form of the invention is illustrated in Figs. and 8. In this modification, the reflector units and luminous discs are entirely separate and distinct from each other. The luminous discs are entirely separate and distinct from each other. The luminous discs indicated at 22 may be of any suitable shape, and are adapted to be received in recesses 23 of the sup port 24. These recesses are preferably of the same configuration as the luminous discs 22, so that these discs will fit snugly therein, and be retained by any suitable means such as the nails 25.
From an economical standpoint, the luminous discs 22 shown herein have been illustrated as being circular. The reason for this is that when the luminous plates H have the openings 12 cut therein, the result will be the discs 22, which will have formerly filled the openings [2. Thus, there will be no waste to the luminous material used if both forms of the invention are to be manufactured.
The reflector elements 2@ may be of a suitable form to be received within and retained by a holder element 2i. This holder element may have any suitable form of retainin means, but-preferably will include an inwardly extending annular rib 28 on the sides thereof. The holder member 2i may have any suitable form of base 29, and will be inserted in a recess 38 provided in one side of the support 2 1. Fastening means, such as the nail 3i, may then be used to secure the holder 2! in place in the recess. The holder 21 is preferably formed of a resilient material, or at least the annular rib 28 thereof should be resilient, so thatthe reflector element 25 can be forced into the holder after it is mounted in place on the supporting member i l, and then retained therein by the rib 23.
Any suitable number of the luminous discs 22 and reflector elements 25 may be utilized, but for purposes of illustration, there has been shown one reflector unit 26 having a luminous disc 22 on each side thereof.
In the first form of the invention, the luminous material or area will be located not only closely adjacent and between the reflector elements, but will also completely surround these elements. This is true in both forms of the invention shown in Figs-2 to 6 inclusive. The other forms shown in Figs. '7 and 8 do not have the luminous area surrounding the reflector elements, but they are merely located closely adjacent thereto. In all forms of the invention, however, the basic principal is employed of having at least one reflector unit and an area of luminous material adjacent thereto, both mounted on a supporting member,
whereby the final marker device is adapted to define the edges or limits of passages such as sidewalks, driveways, and the like.
Changes may be made in the form, construction and arrangement of parts from those disclosed herein without in any way departing from the spirit of the invention or sacrificing any of the attendant advantages thereof, provided, however, that such changes fall within the scope of the claims appended hereto.
