Description:
BACKGROUND OF THE INVENTION
The present invention relates to a signpost structure and, more particularly, to a signpost structure including an information-bearing cylindrical sign capable of 360° visibility and legibility.
A wide variety of signpost structures of different types and construction are well-known to the average person. These signposts generally include signs for communicating a variety of different kinds of information to a viewer such as, for example, traffic information, street names, and information for use in connection with specialized applications such as public transportation (e.g., bus stop information). While existing signpost structures perform a very necessary and valuable function, the signs of these signpost structures are generally flat, and accordingly, communicate the information thereon to a viewer only through a very narrow viewing range, typically considerably less than 180°. Thus, in applications where it might be desirable to provide 360° visibility of sign information, for example, in bus stop or street sign applications, existing signpost structures are unsatisfactory. In addition, existing signpost structures generally do not present a distinctly unique appearance to a viewer.
BRIEF SUMMARY OF THE INVENTION
Briefly, in accordance with the present invention, a signpost structure is provided including an information-bearing cylindrical sign which is capable of 360° visibility and legibility and, in addition, is uniquely different and distinguishable from the flat signs of existing signpost structures. The cylindrical sign of the signpost structure of the invention is hollow and is formed from an initially rectangular, flat, flexible sign blank. The cylindrical sign has an outer surface having a plurality of identical items of information thereon and further has first and second side edges. The signpost structure also includes an edge-placement means which places the first and second side edges of the sign blank adjacent to each other thereby forming the initially flat, rectangular sign blank into the hollow cylindrical sign. The plurality of items of information at the outer surface of the sign blank are arranged so that at least one item of information is always presented to a viewer when the side edges of the sign blank have been placed adjacent to each other by the edge-placement means in forming the cylindrical sign. The signpost structure further includes an elongated support member having a cross-sectional area less than the cross-sectional area of the cylindrical sign, and mounting means mounting the cylindrical sign to the elongated support member.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to FIG. 1, there is shown in a perspective view a signpost structure 1 in accordance with a first embodiment of the invention. The signpost structure 1 includes a cylindrical sign 3 bearing multiple identical legends 3a thereon parallel to the axis of the sign 3, an edge stiffening and mounting member 15 used in conjunction with the cylindrical sign 3, and a support structure 5 for supporting the cylindrical sign 3 and the associated edge stiffening and mounting member 15. For purposes of explaining the present invention, it is assumed that the signpost structure 1 is to be used in connection with public transportation. For this reason, the legends "BUS STOP" have been selected for use on the cylindrical sign 3. However, it will be appreciated that for other applications the cylindrical sign 3 may bear any other suitable legends or symbols, whether pictorial in form or otherwise.
The cylindrical sign 3 as shown in FIG. 1 is formed from a flat, rectangular, flexible sign blank such as shown in FIG. 2. The sign blank of FIG. 2 is preferably of a lightweight, weather-resistant and impact-resistant organic plastic material, such as, for example, a cellulose acetate butyrate plastic material or a polystyrene plastic material. For its use in public transportation, the sign blank is preferably selected to be of a basic white color and the "BUS STOP" legends 3a, typically of a black color, are silk-screened together with an upper border 3b and a lower border 3c, both typically of a red color, against the white background. The above combination of colors insures that the cylindrical sign 3 will be eye-catching, both to motorists and pedestrians alike.
As indicated in FIG. 2, the multiple "BUS STOP" legends 3a are arranged vertically on the sign blank and such that each of the legends 3a, with the exception of the left-most legend 3a, is spaced from the preceding legend 3a by a distance a, and the right-most legend 3a is spaced from the right edge of the sign blank by a second, greater, distance b. As will be apparent hereinafter, the dimensions a and b are selected such that when the sign blank is formed into a cylindrical sign, specifically, by slightly overlapping the side edges of the sign blank (the left edge overlapping the right edge), the right-most legend 3a in FIG. 2 then likewise becomes spaced from the left-most legend 3a in FIG. 2 by the aforementioned distance a. As a result, the information content of the cylindrical sign becomes available to a viewer through a range of 360°, that is, a legend 3a of the sign is always visible to a viewer facing the sign.
The sign blank of FIG. 2 also has a plurality of openings 7, 9, 11 and 13 provided therein for use in forming the sign blank into a cylindrical sign, one opening being provided in each corner region of the sign blank. The openings 7 and 9 and the openings 11 and 13 are spaced from each other by a distance c and the openings 7 and 11 and the openings 9 and 13 are spaced from each other by a distance d such that when the sign blank is formed into a cylindrical sign the opening 7 is coaxially aligned with the opening 9 and the opening 11 is coaxially aligned with the opening 13.
To form the sign blank of FIG. 2 into a cylindrical sign, the aforementioned edge stiffening and mounting member 15, shown in detail in the top and front views of FIGS. 3 and 4, respectively, is employed. The edge stiffening and mounting member 15 is basically an S-shaped element, typically of sheet metal, and includes a pair of diagonally opposed curved end portions 15a and 15b separated by an integral flat portion 15c. The curved end portions 15a and 15b of the edge stiffening and mounting member 15 define spaces for receiving the opposite side edges of the sign blank. Specifically, the curved end portion 15a of the edge stiffening and mounting member 15 receives the right edge of the sign blank and the curved end portion 15b receives the left edge of the sign blank. The flat portion 15c of the edge stiffening and mounting member 15 further has a pair of openings 17 provided therein and spaced apart from each other by the aforementioned distance d so as to be coaxially aligned with the pairs of openings 7, 9 and 11, 13 of the sign blank when the side edges of the sign blank have been inserted into and received in the respective curved end portions 15a and 15b of the edge stiffening and mounting member 15.
When the side edges of the sign blank have been inserted into and received by the curved end portions 15a and 15b of the edge stiffening and mounting member 15, as mentioned above, the cylindrical sign so formed may be attached, together with the accompanying edge stiffening and mounting member 15, directly to the aforementioned support structure 5. The support structure 5 is preferably of a type described in detail in U.S. Pat. No. 3,628,296, to Herbert J. Henry, and assigned to the same assignee as the present invention. The support structure 5 comprises, as shown in FIG. 1, an elongated longitudinally perforated tubular sign support post 5a and a longitudinally perforated tubular anchor sleeve 5b inserted into a base medium (e.g., a sidewalk or the ground) and into which the sign support post 5a is telescoped and suitably attached, for example, by a nut-and-bolt arrangement. As is evident from FIG. 1, the tubular sign support post 5a (and also the tubular anchor sleeve 5b) has a cross-sectional area substantially smaller than the cross-sectional area of the cylindrical sign 3, as taken in a plane normal to the central (longitudinal) axis of the sign 3. The tubular members 5a and 5b are typically of metal and are commercially available from the Unistrut Corporation, Wayne, Mich., under the trade name "Telespar."
To attach the aforedescribed cylindrical sign and the accompanying edge stiffening and mounting member 15 to the support structure 5, specifically, to the sign support post 5a, a pair of threaded bolts are simply passed through the pairs of openings 7, 9 and 11, 13 in the cylindrical sign, through the associated openings 17 in the edge stiffening and mounting member 15, through opposed pairs of openings in opposed sides of the sign support post 5a, and then threaded into associated nuts. It will be appreciated that the large number of openings in the sides of the sign support post 5a permit the cylindrical sign and the associated edge stiffening and mounting member 15 to be attached thereto at any one of several possible points along the length thereof. A top view of the completed signpost assembly 1 is shown in FIG. 5.
The signpost structure 1 of FIG. 1, as described hereinabove, offers many advantages and features. The cylindrical sign of the signpost structure 1, by virtue of its configuration and use of several colors, is unique and readily distinguishable from conventional flat signs. In addition, it is able to withstand the normal effects of weather, it is not susceptible to rusting and, due to its resiliency and flexibility, is not readily susceptible to being significantly damaged, for example, due to vandalism or as a result of accidental vehicular impact. In addition, the sign has sufficient thickness (e.g. 0.040 in.) and stiffness to maintain its shape without the requirement of additional support beyond that provided by the edge stiffening and mounting member 15 and the sign support post 5a. Further, the cylindrical sign is lightweight and may be quickly demounted from its support post and, if desired, used elsewhere. Due to the fact that the sign blank from which the cylindrical sign is formed is flat and flexible, the cylindrical sign is conveniently formed on-site, thereby avoiding the necessity of the blank being formed into a cylindrical sign beforehand and then transported to the site. This feature is significant when large numbers of cylindrical signs are to be prepared and storage space does not readily permit the storage of the required number of cylindrical signs.
Referring now to FIG. 6, there is shown in a perspective view a signpost structure 20 in accordance with an alternative embodiment of the invention. The signpost structure 20 of FIG. 6 is similar to the signpost structure 1 of FIG. 1 and, like the signpost structure 1 of FIG. 1, includes a cylindrical sign 21 and a sign support post 22. The signpost structure 20 of FIG. 6 differs most significantly from the signpost structure 1 of FIG. 1 in that the sign support post 22 is positioned centrally of the cylindrical sign 21 rather than being offset with respect to the central axis of the sign as is the case with the signpost structure 1. The respective positioning of the sign support post 22 and the cylindrical sign 21 is achieved by means of an edge stiffening and mounting member 23 as shown in detail in the top and front views of FIGS. 7 and 8, respectively. As shown in FIGS. 7 and 8, the edge stiffening and mounting member 23 includes an S-shaped section 24 having a pair of diagonally opposed curved end portions 24a and 24b for receiving the side edges of the cylindrical sign 21 and a flat portion 24c integral with the portions 24a and 24b, and further includes an L-shaped section 25 integral with and extending away from the curved end portion 24a. The flat portion 24c of the S-shaped section 24 further includes a pair of openings 27, spaced apart from each other by the aforementioned distance d, so as to be coaxially aligned with the openings in the cylindrical sign 21, and the horizontal portion of the L-shaped section 25 also includes a pair of openings 29, also spaced apart from each other by the aforementioned distance d. The edge stiffening and mounting member 23 is typically of sheet metal. To attach the cylindrical sign 21 and its associated edge stiffening and mounting member 23 to the sign support post 22, threaded bolts are passed through the openings in the cylindrical sign 21 and the coaxially aligned openings 27 in the S-shaped section 24 and then threaded into nuts, thereby to secure the cylindrical sign to the edge stiffening and mounting member 23, and threaded bolts are passed through the openings 29 in the L-shaped section 23 and associated opposed pairs of openings in opposed sides of the sign support post 22 and then threaded into nuts, thereby to secure the edge stiffening and mounting member 23 to the sign support post 22. A top view of the completed signpost structure 20 is shown in FIG. 9.
Although preferred embodiments of the invention have been described hereinabove, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the invention as called for in the appended claims.
The present invention relates to a signpost structure and, more particularly, to a signpost structure including an information-bearing cylindrical sign capable of 360° visibility and legibility.
A wide variety of signpost structures of different types and construction are well-known to the average person. These signposts generally include signs for communicating a variety of different kinds of information to a viewer such as, for example, traffic information, street names, and information for use in connection with specialized applications such as public transportation (e.g., bus stop information). While existing signpost structures perform a very necessary and valuable function, the signs of these signpost structures are generally flat, and accordingly, communicate the information thereon to a viewer only through a very narrow viewing range, typically considerably less than 180°. Thus, in applications where it might be desirable to provide 360° visibility of sign information, for example, in bus stop or street sign applications, existing signpost structures are unsatisfactory. In addition, existing signpost structures generally do not present a distinctly unique appearance to a viewer.
BRIEF SUMMARY OF THE INVENTION
Briefly, in accordance with the present invention, a signpost structure is provided including an information-bearing cylindrical sign which is capable of 360° visibility and legibility and, in addition, is uniquely different and distinguishable from the flat signs of existing signpost structures. The cylindrical sign of the signpost structure of the invention is hollow and is formed from an initially rectangular, flat, flexible sign blank. The cylindrical sign has an outer surface having a plurality of identical items of information thereon and further has first and second side edges. The signpost structure also includes an edge-placement means which places the first and second side edges of the sign blank adjacent to each other thereby forming the initially flat, rectangular sign blank into the hollow cylindrical sign. The plurality of items of information at the outer surface of the sign blank are arranged so that at least one item of information is always presented to a viewer when the side edges of the sign blank have been placed adjacent to each other by the edge-placement means in forming the cylindrical sign. The signpost structure further includes an elongated support member having a cross-sectional area less than the cross-sectional area of the cylindrical sign, and mounting means mounting the cylindrical sign to the elongated support member.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to FIG. 1, there is shown in a perspective view a signpost structure 1 in accordance with a first embodiment of the invention. The signpost structure 1 includes a cylindrical sign 3 bearing multiple identical legends 3a thereon parallel to the axis of the sign 3, an edge stiffening and mounting member 15 used in conjunction with the cylindrical sign 3, and a support structure 5 for supporting the cylindrical sign 3 and the associated edge stiffening and mounting member 15. For purposes of explaining the present invention, it is assumed that the signpost structure 1 is to be used in connection with public transportation. For this reason, the legends "BUS STOP" have been selected for use on the cylindrical sign 3. However, it will be appreciated that for other applications the cylindrical sign 3 may bear any other suitable legends or symbols, whether pictorial in form or otherwise.
The cylindrical sign 3 as shown in FIG. 1 is formed from a flat, rectangular, flexible sign blank such as shown in FIG. 2. The sign blank of FIG. 2 is preferably of a lightweight, weather-resistant and impact-resistant organic plastic material, such as, for example, a cellulose acetate butyrate plastic material or a polystyrene plastic material. For its use in public transportation, the sign blank is preferably selected to be of a basic white color and the "BUS STOP" legends 3a, typically of a black color, are silk-screened together with an upper border 3b and a lower border 3c, both typically of a red color, against the white background. The above combination of colors insures that the cylindrical sign 3 will be eye-catching, both to motorists and pedestrians alike.
As indicated in FIG. 2, the multiple "BUS STOP" legends 3a are arranged vertically on the sign blank and such that each of the legends 3a, with the exception of the left-most legend 3a, is spaced from the preceding legend 3a by a distance a, and the right-most legend 3a is spaced from the right edge of the sign blank by a second, greater, distance b. As will be apparent hereinafter, the dimensions a and b are selected such that when the sign blank is formed into a cylindrical sign, specifically, by slightly overlapping the side edges of the sign blank (the left edge overlapping the right edge), the right-most legend 3a in FIG. 2 then likewise becomes spaced from the left-most legend 3a in FIG. 2 by the aforementioned distance a. As a result, the information content of the cylindrical sign becomes available to a viewer through a range of 360°, that is, a legend 3a of the sign is always visible to a viewer facing the sign.
The sign blank of FIG. 2 also has a plurality of openings 7, 9, 11 and 13 provided therein for use in forming the sign blank into a cylindrical sign, one opening being provided in each corner region of the sign blank. The openings 7 and 9 and the openings 11 and 13 are spaced from each other by a distance c and the openings 7 and 11 and the openings 9 and 13 are spaced from each other by a distance d such that when the sign blank is formed into a cylindrical sign the opening 7 is coaxially aligned with the opening 9 and the opening 11 is coaxially aligned with the opening 13.
To form the sign blank of FIG. 2 into a cylindrical sign, the aforementioned edge stiffening and mounting member 15, shown in detail in the top and front views of FIGS. 3 and 4, respectively, is employed. The edge stiffening and mounting member 15 is basically an S-shaped element, typically of sheet metal, and includes a pair of diagonally opposed curved end portions 15a and 15b separated by an integral flat portion 15c. The curved end portions 15a and 15b of the edge stiffening and mounting member 15 define spaces for receiving the opposite side edges of the sign blank. Specifically, the curved end portion 15a of the edge stiffening and mounting member 15 receives the right edge of the sign blank and the curved end portion 15b receives the left edge of the sign blank. The flat portion 15c of the edge stiffening and mounting member 15 further has a pair of openings 17 provided therein and spaced apart from each other by the aforementioned distance d so as to be coaxially aligned with the pairs of openings 7, 9 and 11, 13 of the sign blank when the side edges of the sign blank have been inserted into and received in the respective curved end portions 15a and 15b of the edge stiffening and mounting member 15.
When the side edges of the sign blank have been inserted into and received by the curved end portions 15a and 15b of the edge stiffening and mounting member 15, as mentioned above, the cylindrical sign so formed may be attached, together with the accompanying edge stiffening and mounting member 15, directly to the aforementioned support structure 5. The support structure 5 is preferably of a type described in detail in U.S. Pat. No. 3,628,296, to Herbert J. Henry, and assigned to the same assignee as the present invention. The support structure 5 comprises, as shown in FIG. 1, an elongated longitudinally perforated tubular sign support post 5a and a longitudinally perforated tubular anchor sleeve 5b inserted into a base medium (e.g., a sidewalk or the ground) and into which the sign support post 5a is telescoped and suitably attached, for example, by a nut-and-bolt arrangement. As is evident from FIG. 1, the tubular sign support post 5a (and also the tubular anchor sleeve 5b) has a cross-sectional area substantially smaller than the cross-sectional area of the cylindrical sign 3, as taken in a plane normal to the central (longitudinal) axis of the sign 3. The tubular members 5a and 5b are typically of metal and are commercially available from the Unistrut Corporation, Wayne, Mich., under the trade name "Telespar."
To attach the aforedescribed cylindrical sign and the accompanying edge stiffening and mounting member 15 to the support structure 5, specifically, to the sign support post 5a, a pair of threaded bolts are simply passed through the pairs of openings 7, 9 and 11, 13 in the cylindrical sign, through the associated openings 17 in the edge stiffening and mounting member 15, through opposed pairs of openings in opposed sides of the sign support post 5a, and then threaded into associated nuts. It will be appreciated that the large number of openings in the sides of the sign support post 5a permit the cylindrical sign and the associated edge stiffening and mounting member 15 to be attached thereto at any one of several possible points along the length thereof. A top view of the completed signpost assembly 1 is shown in FIG. 5.
The signpost structure 1 of FIG. 1, as described hereinabove, offers many advantages and features. The cylindrical sign of the signpost structure 1, by virtue of its configuration and use of several colors, is unique and readily distinguishable from conventional flat signs. In addition, it is able to withstand the normal effects of weather, it is not susceptible to rusting and, due to its resiliency and flexibility, is not readily susceptible to being significantly damaged, for example, due to vandalism or as a result of accidental vehicular impact. In addition, the sign has sufficient thickness (e.g. 0.040 in.) and stiffness to maintain its shape without the requirement of additional support beyond that provided by the edge stiffening and mounting member 15 and the sign support post 5a. Further, the cylindrical sign is lightweight and may be quickly demounted from its support post and, if desired, used elsewhere. Due to the fact that the sign blank from which the cylindrical sign is formed is flat and flexible, the cylindrical sign is conveniently formed on-site, thereby avoiding the necessity of the blank being formed into a cylindrical sign beforehand and then transported to the site. This feature is significant when large numbers of cylindrical signs are to be prepared and storage space does not readily permit the storage of the required number of cylindrical signs.
Referring now to FIG. 6, there is shown in a perspective view a signpost structure 20 in accordance with an alternative embodiment of the invention. The signpost structure 20 of FIG. 6 is similar to the signpost structure 1 of FIG. 1 and, like the signpost structure 1 of FIG. 1, includes a cylindrical sign 21 and a sign support post 22. The signpost structure 20 of FIG. 6 differs most significantly from the signpost structure 1 of FIG. 1 in that the sign support post 22 is positioned centrally of the cylindrical sign 21 rather than being offset with respect to the central axis of the sign as is the case with the signpost structure 1. The respective positioning of the sign support post 22 and the cylindrical sign 21 is achieved by means of an edge stiffening and mounting member 23 as shown in detail in the top and front views of FIGS. 7 and 8, respectively. As shown in FIGS. 7 and 8, the edge stiffening and mounting member 23 includes an S-shaped section 24 having a pair of diagonally opposed curved end portions 24a and 24b for receiving the side edges of the cylindrical sign 21 and a flat portion 24c integral with the portions 24a and 24b, and further includes an L-shaped section 25 integral with and extending away from the curved end portion 24a. The flat portion 24c of the S-shaped section 24 further includes a pair of openings 27, spaced apart from each other by the aforementioned distance d, so as to be coaxially aligned with the openings in the cylindrical sign 21, and the horizontal portion of the L-shaped section 25 also includes a pair of openings 29, also spaced apart from each other by the aforementioned distance d. The edge stiffening and mounting member 23 is typically of sheet metal. To attach the cylindrical sign 21 and its associated edge stiffening and mounting member 23 to the sign support post 22, threaded bolts are passed through the openings in the cylindrical sign 21 and the coaxially aligned openings 27 in the S-shaped section 24 and then threaded into nuts, thereby to secure the cylindrical sign to the edge stiffening and mounting member 23, and threaded bolts are passed through the openings 29 in the L-shaped section 23 and associated opposed pairs of openings in opposed sides of the sign support post 22 and then threaded into nuts, thereby to secure the edge stiffening and mounting member 23 to the sign support post 22. A top view of the completed signpost structure 20 is shown in FIG. 9.
Although preferred embodiments of the invention have been described hereinabove, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the invention as called for in the appended claims.
