This invention relates to free standing and readily dissassembleable graphic displays such as those used for trade shows. More particularly, this invention relates to retractable banner stands.
Retractable banner stands are typically used to support and display a relatively large flexible sign or banner. These stands are widely used in reception areas, trade shows, museums, art exhibits, academic and research society meetings, advertising displays, and other areas in which visual information is temporarily displayed. A flexible sign or banner is extended upwardly from a floor-based housing and a post extending from the housing is used to maintain the display banner extended and upright. The banner is wound on a core that is disposed within the housing. The ends of the housing typically comprises two metal plates.
Retractable banner stands are also collapsible, as typical uses of these stands dictates that they be easily and quickly erected, easily and quickly collapsed, and light-weight and compact, and thus easily transported and stored. In many cases, it is desirable that one person, working alone, be capable of simply and quickly erecting, collapsing, and transporting a retractable banner stand.
The flexible sign or banner displayed by retractable banner stands have graphical images disposed thereon, typically on one side. Where it is desirable to view graphical images from both sides of a banner stand, it is known to connect two banner stands together, each with the same size banners, so that the graphic image side of each banner face outwardly. This can be accomplished by simply connecting two housings together and using a single post for supporting both banners. It is also known to have two banners on two different cores extend from a single housing unit with a single post positioned in the middle of the housing for supporting both banners. These double-sided banner stands are typically about twice as bulky and twice as heavy as a single-sided banner stand.
It would be advantageous to provide a retractable banner stand that permitted graphical images to be viewed from both sides of the banner stand, without the additional bulk and weight associated with double-sided banner stands.
An example embodiment of the present invention has a base, two upright posts, a crossbar, and a single banner with graphic image(s) disposed on both sides of the banner. The base generally includes a housing, two housing end cap assemblies, a single core, and a retracting mechanism. The banner is wound around the core, and the retracting mechanism unwinds and winds the banner with respect to the core. The leading edge of the banner is attached to the crossbar, which is wider than the width of the banner. The banner stand has an erect upright mode for displaying the images(s), and a collapsed mode for transporting the banner stand. In the erect mode, the upright posts are retained in the base by means of a quick-release locking mechanism, the banner extends upwardly from the base, and the crossbar engages with, and is supported by, the upper portion of each of the upright posts.
In certain embodiments of this invention, a retractable banner stand assembly has a base, two upright posts extending from the base and a single banner. The banner extends upwardly from the base and is supported by the upright posts. The base is placed on the floor, a table, or other horizontal surface. The base generally includes a housing, two housing end cap assemblies, a single core, a retracting mechanism, and a foot. The core and retracting mechanism are contained within the housing. The banner is wound around the core, and the retracting mechanism unwinds and winds the banner with respect to the core.
A feature and advantage of certain embodiments of this invention, is that the end cap assemblies provide multiple functions, particularly beyond the functions of the end plates in conventional retractable banner stands. The end caps are preferably formed from polymers that present “friendlier” engagement surfaces with floor surfaces than conventional metal end plates. Moreover, the end cap assemblies provide structure for accommodating the components of a quick-release locking mechanism, provide an aesthetically pleasing appearance and provide a recess for the ends of the crossbar when the banner is retracted.
A feature and advantage of certain embodiments of this invention is that the upright posts are retained in the base by means of two quick-release locking mechanisms, each contained within one of the housing end cap assemblies. In a typical retractable banner stand, setup and takedown by a single person is feasible. A person can install an upright post, and then extend the banner with one hand, while holding the post in place with their other hand and reverse the process during takedown. Once the banner is extended to the top of the post, the tension of the retracting mechanism holds all the components in their erected positions. In the case of the present invention, such setup and takedown techniques are not feasible, as there are two upright posts. The use of a locking mechanism permits a single person to quickly and simply setup or takedown the banner stand. The use of locking mechanisms facilitates the extension of the banner into the erected position, engaging the crossbar with the posts during the setup, disengaging the crossbar during takedown, without requiring the operator to attend to maintaining either of the upright posts in their respective sockets. The locking mechanism in certain embodiments, may be actuated by a push button or a pull lever, either by hand or by foot. In certain embodiments a spring actuated detent mechanism can lock the pole in until it is pulled out by a predetermined force to overcome the detent retention force.
A feature and advantage of certain embodiments of this invention is that the minimum distance between the posts is greater than the width of the banner providing a visual “framing” of the banner. Another feature and advantage of certain embodiments of this invention is that the upper (leading) edge of the retractable banner is attached to a crossbar which is wider than the width of the banner. The crossbar engages with, and is supported by, the upper portion of each of the upright posts to support the crossbar and the banner when the retractable banner stand is erected. This can be by means of a prong and hole engagement. In certain embodiments, the sockets for the poles can be positioned such that prongs on the cross bar fit therein when the banner is retracted.
A feature and advantage of certain embodiments of this invention is that the two housing end cap assemblies are located at either end of the housing. This results in a base that is wider than the typical base of a retractable banner stand; each of the housing end cap assemblies adapted to contain a quick-release locking mechanism to retain an upright post.
A feature and advantage of certain embodiments of this invention is that the two housing end cap assemblies are footed. This elevates the housing off the floor, providing clearance for a swivel foot to be attached to the base.
A feature and advantage of certain embodiments of this invention is that an inverted U-shaped frame is attached to the base by way of the vertical legs outboard of the banner slot and with the horizontal leg removably connecting to the vertical legs and supporting the banner.
A feature and advantage of certain embodiments of this invention is that a single banner can display unobstructed views of a graphic image disposed on a first side of the banner, and unobstructed views of a graphic image disposed on the second side of the banner when viewed from a viewing position displaced from and directly in front of each of the respective sides of the banner.
A feature and advantage of certain embodiments of this invention is that the cross bar member supporting the banner can be elevated off of the vertical posts and the vertical posts are retained in their sockets by the retaining mechanism so as to not make disassembly difficult.

Trailing edge 76 may be attached directly to core 34 or through core connection mechanisms that allow replacement of banner 28 with a different banner.
In operation, a user can grasp crossbar 26 and pull banner 28 from housing 32 to display substantially all of graphic image(s) 30 disposed on both sides of the banner. The spring-biasing of the retracting mechanism of core 34 acts to urge banner 28 to be re-wound on core 34, and thus acts to provide a constant retracting force on banner 28. When this retracting force is unopposed, the spring-biasing of the retracting mechanism of core 34 acts to retract banner 28 through slot 88 into housing 32, winding the banner on the core.
Housing 32 can have horizontal surface engagement members such as feet 38 to provide stable support to banner stand 20 on a horizontal surface, such as a floor. Feet 38 are arranged so that they are substantially parallel to housing 32 when banner stand 20 is in the collapsed mode; when banner stand 20 is in the erect mode, feet 38 are arranged so that they are substantially perpendicular to housing 32, as depicted in
In another embodiment (not illustrated), feet 38 can be snapped or slid onto housing 32 and can be removed for transportation and storage.
In operation, banner stand 20 can be transformed from erect upright mode 40 to collapsed mode 42 by a single user. Banner stand 20 can also be transformed from collapsed mode 42 to erect upright mode 40 by a single user. A user can follow the following steps to transform banner stand 20 from erect upright mode 40 to collapsed mode 42: (a) grasp and pull up crossbar 26 so that prongs 84 disengage from cavities 58; (b) slowly release tension on crossbar 26 so that the spring-biasing of the retracting mechanism of core 34 acts to retract banner 28 through slot 88 into housing 32; (c) release crossbar 26 when it contacts housing 32; (d) grasp an upright post 24 in one hand while depressing lock button 60 with the other hand to release the post from the housing; (e) repeat step (d) for the other post; (f) disassemble posts by grasping one segment 48 in each hand, and pulling segments apart, repeat for the other segments, arrange the segments so that they are substantially parallel with each other and store the disassembled post 24; (g) repeat step (f) for the other post; and (h) rotate foot 38 so that it is substantially parallel to housing 32 and store base 22.
A user can follow the following steps to transform banner stand 20 from collapsed mode 42 to erect upright mode 40: (a) remove base 22 from storage container and rotate foot 38 so that it is substantially perpendicular to housing 32; (b) remove post 24 from storage container assemble post 24 by inserting ends of segments 48 one into the other, bungee cord 50 will act to retain segments as assembled; (c) repeat step (b) for the other post; (d) insert post lower locking portion 46 into socket 62 until tab 68 engages with recessed portion 54; (e) repeat step (d) for the other post; and (f) grasp and pull crossbar 26 up towards upper portion 44 and engage prongs 84 into cavities 58.
