This present invention relates generally to a mechanical sign waving machine platform for street side advertising and promotional purposes.
Businesses, schools and other entities have long employed the use of signs and other media to attract, inform, and/or direct customers, such as by advertising a special promotion or event, providing directions to a specific location, and so forth. One popular technique is to utilize or employ individuals to hold signs outside or otherwise near an entities' location to better engage passersby, such as stationing a human sign holder on the side of a busy street in order to draw the attention of motorists. It is thought that a sign that is displayed by a human sign holder is better at attracting and maintaining attention, as compared to the static nature of fixed signs, because the individual holding a hand-held sign may twirl, wave, or otherwise move the sign around, interact with passersby by waving or gesturing, dress in a costume or otherwise add a performance element to the display of the sign, and so forth.
This technique suffers from many drawbacks, some of which are related to sign visibility. For example, the elevation at which a hand-held sign may be displayed is generally limited to how high a person can raise the sign over his or her head, which may limit the visibility range of the sign. Also, a hand-held sign should be large enough to display information effectively, but if too large, the sign may be too cumbersome; a user may not have a hand free to wave to traffic. Further, large signs may block the individual holding the sign from view reducing the interactive impact with motorists and passersby. User fatigue from standing and holding a sign for long periods of time is a major issue, especially if the individual is expending energy to move him or herself, and/or the sign, around. Also, a major issue is the labor cost to employ human sign holders.
To address these limitations, several entities have developed a mechanical sign waving machine to replace human sign holders. These machines typically have their sign waving apparatus mounted on top of a base with wheels. To avoid tipping over, level ground is required. Additionally, most machines can easily blow over on windy days limiting the elevation at which their signs can be displayed. These machines can be heavy especially at their bases making it difficult for users to physically carry and handle. Also, most of these sign waving machines do not have the capability to attach accessories such as mannequins, flags, and extra signs including electrical versions.
Therefore, what is needed is a lightweight, rugged, rust proof, sign waving machine platform that includes a sign waving apparatus plus the capability to attach media accessories such as mannequins, flags and extra signs, all of which as a single unit can freely swing with the wind.
Various embodiments of a sign waving machine platform for store front and street side promotions are disclosed herein. This platform is made from aluminum tubes that support a sign waving apparatus plus an upper web for hanging optional media accessories. The basic embodiment has a vertical spine, consisting of two interconnected aluminum tubing members, which supports the upper web and at the bottom of the spine attaches to a motor housing assembly that encloses a motor that connects to a sign waving frame. The motor housing fits inside the sign waving frame which resembles a box-shaped truss structure. A variety of signs can be attached to all sides of the sign waving frame allowing viewing from many traffic directions. The adjustable upper web provides the mounting sites for accessories such as additional signs, advertising devices, mannequins, and flags to complement those signs attached to the sign waving apparatus.
A battery which can lie on the ground or elsewhere, provides the power to the low speed electric 12-volt gear head motor that is capable of operating at multiple speeds in both clockwise and anti-clockwise directions. The motor's drive shaft is partially exposed outside of the housing and is coupled to an adjustable drive bracket which connects to a bearing assembly attached to the sign waving frame. It is the rotation of the motor drive shaft and the drive bracket that causes movement of the sign waving frame relative to the motor housing. Most of the weight of the sign waving frame and attached signs is supported by support brackets which minimizes the overhung load on the motor drive shaft. These support brackets are mounted to the housing and are connected to other bearing assemblies mounted to the sign waving frame. These support brackets are freewheeling and move in tandem with the drive bracket. The drive and support brackets are all adjustable providing a wide variety of sign motions including a sideways swinging motion and a vertical rocking motion.
The platform is loosely attached at the top to user-furnished structures such as posts, racks or carts to provide a free-swinging motion to counteract the effects of wind. Connectors include zip ties, cords and rope that can be locally purchased in stores. The entire platform plus attachments swing in unison like one large pendulum. Because the spine and motor box set inside the sign waving frame, any signs attached to the sign waving frame may overlap any media hanging from the upper web without interfering in sign movement. This feature can provide a unique visual effect of overlapping dueling messaging. Because all items and loads are hung, the possibility of tipping over is minimal unlike ground based competitive versions that need to sit on level surfaces and can tip over possibly damaging their sign waving apparatuses.
The platform's core structural brace members consist of 2 smaller aluminum insert tubes that slide inside a larger aluminum host tube. Attached to both ends of the host tube are thumb screws and when twisted, press against and pinch the insert tubes to produce a snug, secure fasten. All connecting joints are made from the same large host tube and include thumb screws for fastening. To make more rugged, some slop or spacing between the tubes is designed in, so if dirty or damaged, the insert tubes may still slide and still be snuggly fastened using the thumb screws.
All the brace members can telescope or stretch up to the point where the not-to-exceed markings stamped onto the insert tubes, have become visible. If stretched beyond the markings, the insert tube may slide too far and the thumb screw could miss it. The overall length of the brace members can also be changed by connecting additional host and insert tubes and by providing tubes of different lengths, such as in lfoot increments. Because of this structural versatility, the spine, upper web and sign waving frame has numerous configurations and can substantially stretch or telescope in many directions to accommodate a variety of drive motor configurations and sign sizes. This platform can easily be adapted to support other sign waving apparatuses including competitive versions that sit on top of the ground; basically hanging them off the ground so that they can swing with the wind.
The platform, being made from aluminum tubes, is sturdy, rugged, rust proof, and lightweight. Depending on the configuration and components used, the platform has a display capacity of about 300 pounds; 400 and more if reinforced components are used. It can easily be disassembled for storage by simply un-twisting the thumb screws. In some embodiments, other fastening mechanisms or combinations thereof may be employed including snap buttons, and bolts with nuts. In other embodiments, alternate tube sizes, wall thicknesses, and tube dimensions may be optionally used. In some embodiments, other materials such as composites and plastics might be used instead of aluminum. In other embodiments, the platform's components and members may be coated with a reflective paint or powder coat where the reflection and bright colors can help gain the attention of passersby.
The concepts, features, methods, and component configurations briefly described above are clarified with reference to the accompanying drawings and following detailed descriptions. Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions, sizing, and/or relative placement of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of various embodiments of the inventions.
In the following paragraphs, the present embodiments will be described in detail by way of example with reference to the attached drawings. Throughout this description, the preferred embodiment and examples shown should be considered as exemplars, rather than as limitations on the present embodiments.
Support brackets 540 and 550 mounted to housing assembly 300 are likewise connected to other bearing assemblies 950 mounted to sign waving frame 400. These support brackets 540 and 550 are free wheeling and move in tandem with drive bracket 530. Most of the combined weight of sign frame 400 and its attached signs are supported by support brackets 540 and 550. The overhung weight load on drive bracket 530 is minimal. All the support and drive brackets are adjustable providing a wide variety of sign motions including a sideways swinging motion and a vertical rocking motion.
Upper web 250 provides additional mounting sites for accessories such as electric signs E, mannequins M, and other signs S to complement those signs attached to sign waving frame 400. Using connectors C, spine 200 and web 250 are loosely attached at the top to user-furnished structures such as posts, racks or carts. These attachments provide a free-swinging motion in many directions to counteract the effects of wind W. Because all loads are hung, the possibility of tipping over is minimal unlike competitive versions that sit on the ground requiring a bottom-heavy counterweight arrangement plus level surface; they can still tip over possibly damaging their sign waving apparatuses.
The core structural methodology for platform 100 is based around 2 aluminum tubes; one slides inside the other allowing spine 200, upper web 250 and sign waving frame 400 to stretch or telescope in many directions. Thumb screws 800 are attached to all the connecting joints and are used as an easy-to-use secure fastening mechanism. Spine 200, upper web 250 and sign waving frame 400 have numerous configurations depending on the combination of joints, tube lengths and telescoping. Because of this structural versatility, platform 100 can easily be adapted to support other sign waving apparatuses, basically elevating them off the ground and switching them to a hanging mode that swings. In other embodiments, different motors and sign frame coupling mechanisms such as pins, can easily be attached to sign waving frame 400.
Insert tube 650 easily slides inside host tube 600 and all the joints. As illustrated by the dashed lines in
Shown in
Bearing joint 950 is used to connect drive bracket 530 and support brackets 540 and 550 to sign waving frame 400. Bearing joint 950 consists of a front and rear host tubes 600 welded together. Bearing 955 is bolted to the front-host tube 600 using bolt and lock nut 957. The rear host tube 600 is used to fasten joint 950 to sign waving frame 400. The insert tubes 650 in sign waving frame 400 slide inside joint 950's rear host tube 600 allowing joint 950 to freely slide and then be securely fastened using the thumb screws on joint 950's rear host tube 600.
As shown in
Motor drive shaft 350 protrudes from box 310 and is connected to drive bracket 530. Within bracket 530, shaft coupler 590 and bolt 595 fasten motor drive shaft 350 to one end of sleeve 545. The other end of sleeve 545 is fastened to bearing assembly 950, shown in
Connector bar 510 provides the connection points for brackets 540 and 550 and is attached to both sides of motor box 310 using bolts with lock nuts 520. From 1 to 5 support brackets can be used depending on the loads and envelope size of motor box assembly 300, sign waving frame 400 and its attached signs. This arrangement of support brackets and connector bars supports most of the combined weight of sign waving frame 400 and its attached signs. Being made from aluminum tubes, a typical sign waving frame 400 including bearings weighs about 15 pounds. Average sign weight is about 10 pounds. As a result, the overhung weight on drive bracket 530 and motor drive shaft 350 is minimal.
As shown in
In a different embodiment, one or more sides of sign waving frame 400 can be welded as a single rigid structure replacing the adjustable telescoping version. In such an embodiment, tubes 650 would be inserted into bearing assemblies 950 prior to welding tubes 650 together. This will allow bearing assembly 950 to still slide along tubes 650 before fastening using thumbscrews 800 attached to bearing assembly 950. In a similar embodiment, one or more sides of sign waving frame 400 can be bolted together while still allowing bearing assembly 950 to slide. In another embodiment, a pin mechanism can be used in place of the bearing assembly 950. In other embodiments, a bent and shaped shaft can be used instead of drive bracket 530 and support brackets 540 and 550.
Included in the assembly of sign waving frame 400 are tubes 410 made from insert tube 650 that have drilled holes for fastening signs to frame 400 using bolt 420 and wing nut 430. In some embodiments, other attachment mechanisms could be used such as hook-and-loop fasteners and applying adhesive materials to multiple surfaces of the signs and sign waving frame 400.
Using connectors C, platform 100 can connect to a variety of customer furnished structures including posts, racks and mobile carts. Connectors C include zip ties, cables, rope, clips and other. Platform 100 is fastened only loosely at the top so it can freely swing in many directions with the wind W minimizing aerodynamic forces. All loads and forces on platform 100 are channeled through sign waving frame 400, motor box assembly 300, upper web 250 and spine 200. Platform 100 has a display capacity of about 300 pounds; 400 and more if reinforced components are used. In other embodiments, heavier hanging loads can be supported by using additional tubes and braces plus aluminum tubes with a thicker wall thickness.
The entire platform 100 plus attachments swing in unison like one large pendulum. Because spine 200 and motor box assembly 300 set inside sign waving frame 400, any signs attached to sign waving frame 400 may overlap any media hanging from upper web 250 without interfering in sign movement. This feature can provide a unique visual effect of overlapping dueling messaging.
Platform 100 has numerous configurations depending on the combination of joints, tube lengths plus telescoping. This structural versatility allows sign waving frame 400 to fit over and attach to other industry sign waving apparatuses to elevate them off the ground and switching them to a hanging mode that swings. Furthermore, using upper web 250, additional media and devices can be attached to complement the unique features of such competitive industry apparatuses.
The preferred material for any attached signs should be rigid, lightweight, and weather-proof such as corrugated plastic board. A reflective sign surface such as using reflective paint helps in gaining the attention of passersby. Platform 100 is of multi-piece construction with many common parts, resulting in lower manufacturing and storage cost. Further, providing platform 100 components in a compact customer kit to be assembled by a user may reduce shipping costs. Also, custom reader boards may be offered that include grommets for easy attachment to platform 100. These boards have grommets on all four corners so that they can be connected to other reader boards to increase overall sign size. All platform 100 components and reader boards nest well in the same shipping container that meets requirements for inexpensive air freight with home delivery.
It will be apparent to those skilled in the art that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the invention. The present invention is intended to embrace all such alternatives, modifications and variances that fall within the scope of the appended claims.
