The disclosure relates generally to border trim on a billboard and more specifically it relates to an apparatus and method using aluminum extrusions to form the trim or border of a billboard or sign to house the cable, pulleys, guides, and other individual components of a cable tensioning system for securing and stretching a printed display sheet on a billboard or sign.
Display sheets in the form of printed words, photographs, or drawings on flexible semi-translucent media, such as vinyl, polyethylene, or polypropylene sheets attached to or stretched over a metal or wooden substrate forming an advertising billboard or commercial signage, have been in use for many years and known in the prior art. The display sheets are typically attached to the substrate, which forms the billboard face, by an apparatus, such as a cable tensioning system attached to either the front or the back the substrate. When a frontal attachment method is used, decorative trim is typically placed around the perimeter of the substrate and mounted several inches from the face of the substrate to conceal the attachment apparatus. The trim creates the appearance of a picture frame. However, unlike a picture frame there is a gap of several inches between the trim and the advertising display sheet. When the billboard is mounted high in the air above motorists or pedestrians, the gap is not generally noticeable. But when the billboard is located closer to the ground, the gap is noticeable and can be an undesirable distraction from the advertising display.
Another problem resulting from the gap between the border trim or frame and the substrate, or an exposed cable tensioning system is the accumulation of debris that can occur along the bottom portion of the billboard. On billboards mounted close to the ground, which is a prevalent practice in European and other countries outside of North America, drinking cups, bottles, and other trash is often placed in the gap, which can interfere with the operation of the system when the display face is changed. The trash can also pile up and block vision of a part of the display face and create a potential for injury to a worker removing broken bottles and other hazardous trash placed in the gap.
A recent frontal attachment apparatus and method is the cable tensioning system disclosed in U.S. Patent Application No. 20090019570 filed Jul. 16, 2007, comprised of cables, anchor plates, cable guides, and locking clips, which application is incorporated herein by this reference in its entirety. Each of the individual components of existing cable tensioning systems is attached directly to the substrate or to the support structure of the billboard using bolts or screws. Holes must be drilled in the substrate at specified locations for each cable guide and pulley. If the installer incorrectly places a component, the cable system may not function properly. For example, the cable may slip off an incorrectly placed cable guide. As a result, each incorrectly installed component must be removed, new holes drilled, and screws or bolts attached in the correct location.
Templates with mounting and hole drilling locations may be used on signs and smaller billboard but the use of templates for large billboards is impractical because of the size of the template required, the cost of the template, and the difficulty inherent in handling and attaching the template onto the billboard substrate. Another problem is when the cable tensioning system is positioned on the perimeter of the substrate it is exposed to the elements subjecting it to rust and other deterioration over time if left uncovered.
Therefore, it is readily apparent that there is a recognizable unmet need for an apparatus and method to house a cable tensioning system positioned around the perimeter of billboard, wherein a billboard with a cable tensioning system may be configured to fit one or more sizes and configurations of a billboard, to conceal the cable tensioning system, cover the gap between the frame and the display sheet, and eliminate the need for a separate border trim on around the perimeter of the billboard.
Briefly described, in example embodiment the present apparatus overcomes the above-mentioned disadvantages and meets the recognized need for an apparatus and method to house cable tensioning system positioned around the perimeter of a billboard comprising, in general, a trim base C-shaped channel having a front face, a bottom face, and a hanger face configured to form a trough or C-channel; one or more T-tracks and splice tracks positioned on the interior of the trough or C-channel for mounting a plurality of components of a cable tensioning system; a concave member positioned on the front face; a trim cap having a support extension and a contact extension configured to rotate about the concave member, wherein the trim cap is configured to cover the trough or open top of the C-channel; and a spring positioned between one hanger section and the support extension, wherein the spring is configured to rotate the trim cap about the concave member and, thus, functions to conceal from public view the cable, pulleys, guides, and other individual components of a typical billboard cable tensioning system used to secure and stretch a printed display sheet, and protects the components from weather, dust, and undesirable debris.
According to its major aspects and broadly stated, the present apparatus meets the recognized need for a border trim assembly comprising, in general, a C-channel member having a front section, a concave member positioned on the front section, a bottom section, a hanger section, and a trim cap having a support extension and a contact extension configured to rotate about the concave member, wherein the trim cap is configured to cover the gap, trough or open top of the C-channel.
In an exemplary embodiment, the apparatus and method to house a cable tensioning system around the perimeter of a billboard, includes a border trim assembly for a billboard having an exposed display sheet tension system for attachment of a display sheet to the billboard panel, the assembly comprising: a structure having a mount section configured to position the display sheet tension system, a hanger section configured to affix the structure to the billboard panel, and a support section; a concave member positioned on the support section; and a trim cap configured to rotate about the concave member, wherein the trim cap is configured to cover the display sheet tension system.

In still a further exemplary embodiment, the method of covering an exposed display sheet tension system for attachment of a display sheet to the billboard panel includes the steps of providing a structure having a mount section configured to position the display sheet tension system, a hanger section configured to affix the structure to the billboard panel, and a support section, a concave member positioned on the support section, and a trim cap configured to rotate about the concave member, wherein the trim cap configured to cover the display sheet tension system, mounting the border trim assembly to the billboard frame, adjusting the trim cap to fit the gap between the display sheet and the support section, and positioning a leaf spring between the support section and the trim cap wherein the spring is configured to rotate the trim cap about the concave member to cover the display sheet tension system.
In still a further exemplary embodiment, the method of filling a gap between a billboard frame and a display sheet includes the steps of providing a border trim assembly, which further comprises a C-channel having a front section with one T-slot, a splice slot, or a combination splice and T-slot, and a concave member positioned on the front section; a bottom section with one or more T-slots; a hanger section with two or more T-slots configured to affix the C-channel to the billboard frame or billboard panels and one or more T-slots to affix components of a cable tensioning system within the trough of the C-channel; and a trim cap having a support extension and a contact extension configured to rotate about the concave member wherein the trim cap is configured to cover the gap; hanging the trim assembly to the billboard frame; adjusting the trim assembly to fit the gap between the display sheet and the billboard frame; and positioning a leaf spring between the hanger section and the support extension wherein the leaf spring is configured to rotate the trim cap about the concave member to cover the gap.
The present disclosure may utilize aluminum extrusions consisting of a C-channel trim base with two or more T-shaped channels or T-slots and a hinged cap with a leaf spring to facilitate opening and closing. Bolts inserted into the T-slots secure the extrusion to the frame or panel sections of the billboard, depending upon the make-up of the billboard structure. With an alternative embodiment, the trim base is mounted onto an L-shaped bracket, which has been attached to the billboard frame, a wall, or other flat surface. [Although “billboard” is used throughout this application, the present disclosure may also be used on smaller signs. Therefore, the use of “billboard” herein also includes “signs.”] Bolts and nuts in the T-slots secure cable guides, pulleys, and other cable tensioning system components. The aluminum extrusion can be virtually any length, but to facilitate ease of handling or comply with cargo shipping restrictions, the length of the extrusions can be cut into individual sections for handling ease and shipping compliance. During installation individual extrusion sections can be joined together where the sections abut with metal splice plates inserted into splice tracks on the interior of the C-channel member.
Accordingly, a feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a trim cap attached to the trim base with a ball and socket-type hinge.
Still another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a concave member positioned at the top of the front face of the C-channel configured to form the socket into which the hinge pin of the trim cap is inserted to rotate within the concave member when the trim cap is opened and closed.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a leaf spring positioned between the mount leg on the top of the front face of the C-channel and the support extension of the trim cap to provide tension to open and close the trim cap.
Yet another feature of the apparatus to house cable tensioning system around perimeter of billboard is its ability to provide a base stop at the top of the front face configured to form a surface against which the stop leg on the trim cap strikes, preventing the cap from rotating beyond the stop or opening too far, which could allow the leaf spring to detach from the assembly.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a closing stop on the top surface of the hinge leaf spring mount, which is provided to prevent the trim cap from closing beyond 90 degrees or another desired angle and prevents the trim cap from separating from the trim base at the hinged connection.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a trim base having an elongated opening on the bottom section into which one leg of an L-shaped bracket can be inserted. Moreover, the other leg of the bracket is attached by bolts or screws to a wall eliminating the need for a metal or wood substrate backing
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of billboard is its ability to provide one end of the leaf spring configured to lie in a groove in the leaf spring mount near the top of the front section and other end of the leaf spring configured to lie in a corresponding groove in the trim cap leaf spring mount located on the underside of the trim cap.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of billboard is its ability to provide a top portion of the trim cap configured to have a tool lip into which a tool with a flat blade such as a flat screw driver or hook can be inserted to open the trim cap.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a small gap between the top of the trim cap and the bottom of the tool lip to prevent pedestrians from opening the trim cap by hand.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a lock inserted into the cap to prevent the trim cap from being opened by others.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a gap between the top of the trim cap and the bottom of the tool lip large enough to allow opening of the trim cap by placing fingers into the gap and pulling the trim cap open without a tool. This is an exemplary embodiment on billboards installed in a location not accessible by the general public.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a trim cap with a length equal the width of the C-channel from the front face of the front section to the rear face of the mounting section, which results in the trim cap forming a 90 degree closure on the top of the C-channel.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a trim cap with a length configured to exceed the width of the C-channel, which results in the trim cap forming an angle slanting down from the display media to the front face of the front section. This is an exemplary embodiment on billboards mounted low to the ground. The downward angle of the trim cap will cause objects such as cups, bottles, and other objects to slide off the trim cap.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide the contact end of the trim cap, which rests against the display media configured with a rounded hook or rounded bead to prevent the edge from catching or cutting the display media when the trim cap is opened and closed.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide tension, created by the leaf spring, configured to cause the contact end of the trim cap to press against the display media, holding it against the substrate or panel sections. This tension helps to remove wrinkles in the display media.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a trim cap configured to reduces rain, snow and other damage to the tensioning system components.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a trim base having an angled baffle on the rear face above the mounting T-slots, wherein the display media runs across the apex of the baffle causing the display media to stretch smoothly across the face of the billboard. This is a exemplary embodiment for back-lit signs, in which a light source such as light emitting diodes (LED's), fluorescent tubes, or incandescent bulbs, are mounted on a back substrate providing illumination from behind the display media.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide billboard trim that can accommodate various sizes and dimensions of billboards.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a hinge configuration between the C-channel and trim cap that is easy to assemble.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a C-channel member and trim cap configured to withstand the weather.
Yet another feature of the apparatus to house a cable tensioning system around the perimeter of a billboard is its ability to provide a trim cap that can accommodate various sizes of billboards and different sized gaps between the display sheet and the billboard trim.
