Abstract
A flag holder for use on a sign stand which includes a support member and a spring member so configure to releasably secure a plurality of flags. The support member includes a mounting surface adaptable to secure the flag holder to the sign stand, a guide pocket or flange extending from the mounting surface, and a base flange extending from the mounting surface to support the end of the staff. The spring member of the flag holder is secured to the support member and engages the flag staff. The spring member applies enough force on the flag staff to prevent displacement of the flag, yet allows the staff to be easily inserted and removed.
Description




BACKGROUND OF THE INVENTION




1. Technical Field




The present invention relates generally to sign and stand devices for signs or other display devices, and more particularly to an improved apparatus used on a sign stand for holding flags.




2. Discussion




Numerous sign stand devices have been designed for displaying advertisements and information to the public. On construction sites, for example, such signs are typically positioned on an upright member of sign stands that are either anchored in the ground, held in place by sand bags or other heavy objects, or spring-mounted on bases which allow them to bend or deflect relative to the base without tipping over under high wind forces. Signs commonly used at construction sites or at roadside emergency situations are square, rectangular, or diamond in shape, flat in configuration, made of metal or wood, and have pertinent informative or warning messages or symbols on them. In addition, flexible roll-up retro-reflective signs are also being used today. These signs are made out of a heavy duty flexible and foldable material, such as vinyl or reinforced cloth or plastic.




In addition to the information displaying sign panel, sign stand devices may also include flags mounted on them to alert observers to the sign. These flags are generally mounted to the top of the upright member of the sign stand to provide high visibility to motorists that pass by them. Various devices are currently used to mount these flags onto the sign stand.




One such device is a steel bracket secured to the upper end of the upright member of the sign stand by means of conventional fasteners extending through mounting holes in a vertical portion of the bracket and through the upper end of the upright member. This bracket includes an upper horizontal portion, a vertical portion, an intermediate horizontal portion vertically spaced from the upper horizontal portion, and an angulated lower portion. The staffs of the flag are inserted through a number of openings in the upper horizontal portion of the first piece, through a corresponding number of openings in the intermediate horizontal portion, and abut the lower portion.




One disadvantage of this design is that the flags are not secured in the bracket holder. This makes them susceptible to inadvertently being separated from the bracket. For example, inclement weather conditions, especially high winds, may cause the flags to be blown out of the bracket.




A variation of the one piece steel bracket which addresses the problem of flag separation uses a second substantially U-shaped steel piece in association with the first steel bracket which functions as a locking mechanism to rigidly secure the flag staffs in place. The locking mechanism utilizes a pair of threaded fasteners such as nuts and bolts or screws to clamp the flag staff between the first and second brackets.




This bracket, like many of the other brackets presently in use for mounting or attaching such signs to the sign stands, is often difficult and time consuming to operate, and typically is relatively heavy and bulky thereby making them inconvenient for use in construction or emergency situations. Other notable drawbacks of the locking mechanism are increased weight, increased size, additional fabrication labor and additional cost which are a byproduct of the added U-shaped bracket. Furthermore, the threaded fasteners can become separated and lost from the flag holder rendering the locking mechanism unusable.




In addition, because the sign stands are often used in roadside locations, they on occasion became involved in collisions with motor vehicles. Both state and federal agencies have instituted various motor vehicle safety standards to address this issue. Specifically, NCHR-350 is a recently enacted federal law that relates to crash performance of roadside sign stands. In view of the more stringent requirements of NCHR-350, improvements may be required in the sign stands in order for them to meet these standards. In particular, some bracket designs currently in use may contribute to the poor performance of the sign stands during the tests because of their weight, size, and configuration.




Therefore, there is a need for an improved flag holder for use on a sign stand device which is relatively light in weight, compact in size, economical to produce, and which can be made operational with relative ease and expediency.




SUMMARY OF THE INVENTION




It is therefore an object of the present invention to provide a sign stand with a flag holder that can be set up and made operational with as little difficulty and as quickly as possible.




It is a further object of the present invention to provide a flag holder that is lightweight.




Another object of the present invention is to provide a flag holder that is economical to produce.




It is still another object of the present invention is to provide a flag holder that can accommodate different size flag staffs.




Accordingly, the present invention is directed to an improved flag holder that is mountable to a sign stand. The flag holder includes a support member and a spring member which allow a plurality of flag staffs to be secured in place. The support member has a mounting surface adaptable to secure the flag holder to the sign stand. The support member further includes a guide pocket or flange extending outwardly from the mounting surface. The guide flange has an opening formed therethrough to receive the flag staff. The support member also includes a base flange extending outwardly from the mounting surface. The spring member of the flag holder is secured to the support member and has a flange with an arcuate configuration which engages the flag staff, wherein the flange is releasably positionable to disengage the flag staff. The flange applies sufficient force on the flag staff to prevent flag separation, yet allows the staff to be easily inserted and removed. In addition, the flag holder is adaptive to accommodate various flag staff sizes.




The present invention uses this simple, elegant design to provide a flag holder that is lightweight and easily transportable. The support member of the flag holder may be formed of a plastic material which is lightweight and durable. The lightweight nature of the flag holder allows for convenient set-up and reduces the overall weight of the sign stand in order to better accommodate federal motor vehicle safety standards.




Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood however that the detailed description and specific examples, while indicating preferred embodiments of the invention, are intended for purposes of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




As the drawings show preferred embodiments of the present invention, one skilled in the art will readily recognize that the principles of the invention are well adapted for application to devices other than sign and stand assemblies other than those shown in the drawings. Furthermore, one skilled in the art will readily appreciate that various adaptations of the preferred embodiments may be combined or otherwise modified without departing from the spirit and scope of the invention.





FIG. 1

shows a flag holder


20


in use on a sign stand


8


with a sign


10


mounted on an upright


12


. The upright


12


is supported on the ground preferably by a plurality of ground-engaging legs


14


and a spring mechanism


16


which allow the sign


10


and upright


12


to deflect relative to the base assembly


17


in a downward direction when subjected to wind forces and then resiliently return to the normal upright position shown in FIG.


1


. It is understood, of course, that the flag holder


20


of

FIG. 1

may also be used with other types of sign stands or frame members, whether permanently anchored or portable.




The upright


12


may be composed of any conventional material which is sturdy enough to be used for the purpose described herein, but is preferably composed of a hollow metal construction, such as aluminum or steel. The cross-sectional shape of the upright


12


is preferably square (as shown in FIGS.


1


and


2


), although it should be understood that the frame can have any suitable cross-sectional size and shape so long as it can be used as a stand for a construction sign or similar display.




The sign


10


has a large flexible and foldable sign panel


15


typically having a warning, message or symbol on one side and a pair of cross-braces


11


and


13


pivotally attached to one another on the other side. The flexible sign panel


15


is preferably composed of a heavy-duty material such as vinyl or reinforced cloth or plastic, for example. The cross-braces


11


and


13


are made of a relatively rigid material (such as fiberglass, metal, or wood) and serve to brace and support the flexible sign panel in its fully extended position. As shown in

FIG. 2

, one of the cross-braces


11


is pivoted to a horizontal position when the sign is mounted to the upright


12


, while the other cross-brace


13


is vertically situated. Any of the attaching means known in the art may be used to retain the corners of the sign panel at the ends of the cross-braces


11


and


13


in order to erect the sign to its display configuration. A presently preferred configuration is the Duralatch® attachment system manufactured by Marketing Displays International, Inc. of Farmington Hills, Mich. When the sign


10


is removed from the upright


12


and is to be taken down, at least two comers of the flexible sign panel material are detached from the other ends of their corresponding cross-brace, and the cross-braces are pivoted to a generally parallel, mutually aligned relationship. The flexible sign panel


15


which remains attached to one of the cross-braces, may then be folded or rolled up around the mutually-aligned cross-braces for compact, convenient storage.




As seen in

FIGS. 1 and 2

, a plurality of warning flags


18


at the top of the upright


12


are held in place by the flag holder


20


. Flags


18


are of the type having a flag staff


19


which are commonly used as a high level warning for approaching traffic. Although the flag holder of the present invention is shown in the drawings as preferably holding three flags, it would be understood by one skilled in the art that the flag holder may be adapted to hold more or less than three flags without departing from the spirit and scope of the present invention.





FIGS. 2-7

illustrate a first preferred embodiment of the present invention. The flag holder


20


includes a support member


22


and three spring members


24


disposed in guide pockets


26


for releasably securing the flag staff


19


to the sign stand


8


. The support member


22


is preferably diamond-shaped and includes a web


28


interconnecting the guide pockets


26


which extend outwardly from a front face


22




a


of the support member


22


. The diamond-shaped configuration of the support member


22


minimizes the width of the flag holder


20


to make it light and compact.




The flag holder


20


of the present invention may be mounted to the sign stand


8


by a variety of methods. As is shown in

FIG. 4

, the back side


22




b


of the support member


22


has a pair of guide ribs


29


extending therefrom. In a first preferred mounting method, the guide ribs


29


are used to slide the support member


22


directly onto the vertical cross-brace


13


(not shown) of the sign assembly


10


to align the flag holder


20


into mountable position. The flag holder


20


can then be secured to the cross-brace


13


by suitable fastening means, such as threaded fasteners, rivets, or snap-fit. This method is preferably used in conjunction with the Duralatch® attachment system manufactured by Marketing Displays International, Inc. of Farmington Hills, Mich.




The compact configuration of the flag holder


20


along with its ability to be mounted directly to the cross-brace


13


allow the flag holder


20


to remain attached to the sign assembly even when the sign assembly is not in use. When the sign


10


is removed from the frame member


12


and is to be taken down, at least two corners of the flexible sign panel material are detached from the other end of their corresponding cross-brace. The cross-braces


11


and


13


are pivoted to a generally parallel, mutually aligned relationship. The flexible sign panel


15


, which remains attached to the cross-braces


11


and


13


, along with the flag holder


20


, which also remains attached to one of the cross-braces


11


and


13


, may then be folded or rolled up around the mutually aligned cross-braces for compact, convenient storage.




In a second preferred mounting method, conventional fasteners such as rivets or lock nuts and bolts may extend through mounting holes


30


formed in support member


22


to secure the flag holder


20


to the upright


12


. The guide ribs


29


may be used in this mounting method to locate the flag holder


20


for alignment in its mounting position on the upright member


12


.




With reference again to

FIGS. 3 and 5

, the three guide pockets


26


extend outwardly from the front face


22




a


of the support member


22


. The guide pocket


26


is defined by upper retainer or flange portion


32


, a pair of side walls


33


, and base flange


34


extending outwardly from the web


28


. The guide pocket


26


locates and supports a flag staff


19


in flag holder


20


so as to define a staff receiving volume. The spring members


24


are secured within the guide pockets


26


.




Base flange


34


includes a bottom wall


36


that extends outwardly from the front face


22




a


. Opposite the front face


22




a


, a lip


38


extends upwardly from the bottom wall


36


and toward the web


28


to form a slightly acute angle


40


. A groove or relief


42


is formed in front face


22




a


within the guide pocket


26


. In this manner, base flange


34


forms a cavity into which the spring member


24


may be “snapped” into position. As best seen in

FIG. 5

, the groove


42


in the front face


22




a


engages upper edge


43


of the spring member


24


for releasably securing the spring member


24


in the guide pocket


26


.




As seen in

FIGS. 6 and 7

of the drawings, the spring member


24


is a resilient component that accommodates various diameter flag staffs (normally ¾″ and typically ranging between {fraction (5/8-13/16)}″) and includes a vertical wall


44


and a horizontal wall


46


fabricated with a slightly obtuse angle


48


formed therebetween such that when the spring member


26


is placed into one of the guide pocket


26


, the vertical wall


44


is brought into a substantially orthogonal position


50


(i.e., about 90° as shown in

FIG. 5

) with respect to the horizontal wall


46


. By reducing the angle between the vertical and horizontal walls


44


,


46


, a retention force is generated in the spring member


26


to releasably retain the spring member


24


within the guide pocket


26


.




A downwardly angled tab or flange


52


extends from the vertical wall


44


and functions as a retaining element to secure the flag staff


19


in the guide post


26


. The downwardly angled flange


52


is resiliently deflectable and has an arcuate relief


54


formed in the free end. The radius of relief


54


is smaller than that of flag staff


19


, preferably having a diameter in the range of {fraction (3/8-9/16)}″ (approximately 50%-70% of the staff diameter), thereby allowing the comers


56


of the arcuate relief


54


to engage the staff


19


and make a positive lock therewith. As the flag staff


19


is inserted, the flange


52


deflects downwardly. Once inserted, the flange


52


and its comers


56


formed by relief


54


apply pressure on or bite into the staff


19


and frictionally prevent its upward movement. This configuration also allows the flag holder


20


to securely retain different size staffs


19


.




A clamping force on the flag staff


19


is provided by a cantilevered spring element


57


comprising flange


58


which angles upwardly and inwardly and tab


62


which intersects flange


58


at corner


63


. Spring element


57


works in association with the flange


52


to secure the flag staff


19


in place. The intersection of horizontal wall


46


and flange


58


creates a slightly acute angle


60


. To provide sufficient freedom of movement of spring element


57


, the angle


40


formed between the lip


38


of the base flange


34


is slightly greater than the angle


60


formed between the horizontal wall


46


and the flange


58


. Spring element


57


is adapted to apply a clamping force onto a flag staff inserted within the flag holder


20


. The clamping force may be removed by deflecting the spring element


57


away from the front face


22




a


, allowing the flag staff


19


to be removed from the flag holder


20


.




The tab


62


can be depressed downwardly away from support member


22


to pull the spring element


57


away from the support member


22


, thereby allowing the removal of the flag staff


19


. The tab


62


is large enough to provide a surface that may be easily gripped by, for example, a worker wearing large, bulky gloves.




The web


28


of the support member


22


includes upper and lower access holes


64


,


66


. Lower access hole


66


provide access to each of the spring members


24


. If, for instance, the spring member


24


needs to be removed from the support member


22


, a tool, such as a screwdriver, may be inserted through the appropriate lower access holes


66


to press against the vertical wall


44


of the spring members


24


, thereby forcing the vertical wall


44


to deflect away from the front face


22




a


and out of the groove


42


. In this way, the spring member


24


may be popped out of its installed position in the guide pocket


26


.




The access holes


64


,


66


also reduce the weight of the flag holder


20


and facilitate manufacturing thereof. More specifically, the support member


22


may be formed using an injection molding process. Conventionally, many intricate parts have been formed by an expensive injection molding process which requires the use of cams, slides and pins. However, by aligning the access holes


64


,


66


with the position of flanges


32


,


34


, a more simple and less expensive parting die may be used to fabricate the support member of the present invention, thereby reducing the overall cost and complexity of the molding process.





FIGS. 8-10

illustrate an alternate embodiment of the flag holder according to the principles of the present invention. The flag holder


120


includes a support member


122


and three spring members


124




a


,


124




b


, and


124




c


. The support member


122


includes a guide flange


126


and a web


128


. The spring members


124


are secured to the support member


122


by rivets (not shown) or similar known mounting mechanism, such as threaded fasteners or a suitable adhesive. Conventional fasteners


127


may extend through support member mounting holes (not shown) to secure the flag holder


120


to the upright frame


12


. A flag staff


19


(not shown) may be releasably inserted through an opening


132


in the guide flange


126


of support member


122


.




The spring members


124


are preferably spaced more closely to one another than are the openings


132


so that the flags staffs


19


diverge, thereby avoiding interference with one another and increasing their visibility. As presently preferred, the embodiment of

FIGS. 8-10

uses a spring member configuration similar to that illustrated in

FIGS. 5 and 6

of the drawings and described herein. The spring member


124


includes a generally vertical wall


144


and a horizontal wall


146


. The included angle between vertical wall


144


and horizontal wall


146


is approximately 90°. An elastically deformable flange


152


extends from the vertical wall


144


downwardly towards horizontal wall


146


. The downwardly angled flange


152


includes an arcuate cutout (not shown, but similar to that as shown in

FIG. 7

) of a radius slightly smaller than that of flag staff


19


, thereby allowing the comers


156


of the arcuate cutout to engage the staff


19


and make a positive lock. As the flag staff


19


is inserted, the flange


152


may deflect slightly downwardly. Once the flag staff


19


is inserted, the flange


152


and its comers


156


bite into the staff


19


and frictionally prevent its upward movement in a manner heretofore described.




A clamping force on the flag staff


19


is provided by a cantilevered spring element


157


which includes an upwardly angled flange


158


and release tab


162


. The release tab


162


can be depressed downwardly away from mounting surface


128


to bend or rotate the flange


158


away from the mounting surface


128


. This deflection removes the clamping force on the flag staff


19


, thus allowing it to be disengaged from the downwardly extending flange


152


and removed from the flag holder


120


. The tabs


162


are large enough to provide a surface that may be easily gripped by, for example, a worker wearing large, bulky gloves.





FIGS. 11-14

illustrate another alternate embodiment of the flag holder according to the principles of the present invention. The flag holder


220


includes a support member


222


and a spring member


224


. The support member


222


includes a guide flange


226


, a mounting surface


228


, and a base flange


234


. The spring member


224


has a vertical wall


244


for mounting to the support member


222


and a release tab section


262


, which includes three tab portions


262




a


,


262




b


, and


262




c


. As seen in

FIGS. 11

,


12


, and


14


, each tab portion


262




a


,


262




b


, and


262




c


is a downwardly angled flange extending away from the mounting surface


228


of the support member


222


. Arcuate reliefs


254




a


,


254




b


and


254




c


which are complementary to the flag staff


19


are formed in the free end of each tab portion


262


.




The spring member


224


is secured to the support member by rivets


266


, as shown in

FIGS. 11-12

, or by similar known mounting mechanism, such as threaded fasteners or a suitable adhesive. Conventional fasteners


227


extend through spring member mounting holes


229


and through support member mounting holes


230


to secure the flag holder


220


to the upright


12


.




An opening


232


formed in the guide flange


226


of support member


222


is adapted to receive a flag staff


19


. Staff


19


also passes through the release tab portions


262


of spring member


224


by way of arcuate relief


254


. The release tabs


262


, and thus reliefs


254


, are preferably spaced more closely to one another than are the openings


232


so that the flags staffs


19


diverge, thereby avoiding interference with one another and increasing their visibility.




The release tab portion


262


of the spring member


224


are elastically deformable such that they resiliently deflect downward to allow a staff


19


to be inserted into the flag holder


220


. Each relief


254


preferably has a configuration such that it engages the perimeter of the staff


19


. Once the staff


19


is inserted, engagement with the spring member


224


prevents its upward removal. The release tab portion


262


exerts a frictional force on the staffs


19


and works in association with the base flange


234


of support member


222


to secure the flags in the flag holder


220


. The bottom of each flag staff


19


is seated in the flag holder


220


in such a way that it abuts the base flange


234


of support member


222


. As shown in the preferred embodiment of

FIGS. 11-14

, the base flange


234


is formed so that a vertical lip


238


constrains the bottom of each staff


19


in a direction which opposes the force exerted by the release tab


262


. The flag staff


19


can be removed by manually depressing the release tab


262


downwardly towards the mounting surface


228


so that it no longer engages the staff


19


, thereby allowing it to be freely removed.





FIGS. 15-17

illustrate an alternate embodiment of the flag holder according to the principles of the present invention. The flag holder


320


includes a support member


322


and three spring members


324




a


,


324




b


, and


324




c


. The support member


322


includes a guide flange


326


, a mounting surface


328


, and a base flange


334


. A plurality of openings


332


are found in the guide flange


326


.




The spring members


324


include a vertical wall


344


secured to the support member


322


by rivets


366


, as shown in the

FIGS. 15-17

, or by similar known mounting mechanism, such as threaded fasteners or a suitable adhesive. Conventional fasteners (not shown) extend through center spring member mounting holes (not shown) and support member mounting holes to secure the flag holder


320


to the upright frame


12


. A release tab


362


extends downwardly and outwardly from the vertical wall


344


. An aperture


354


is formed in the release tab


362


for receiving a flag staff


19


. The release tabs


362

432


of guide flange


426


and through relief


454


of spring member


424


. The release tab portions

As presently preferred, the support member of each embodiment is formed of a lightweight plastic material which is readily formable into the desired shape. The spring member is preferably formed of a spring steel or other suitable material. The tabs of the spring member are elastically deformable to allow resilient downward deflection during installation and removal of the flag staffs. The design of the flag holder in accordance with the present invention allows the flags to be firmly secured in place by the association of the spring member with the support member. As such, the need for an additional clamping bracket is rendered unnecessary. This allows the flag holder of the present invention to be lighter than other lock systems while maintaining its ability to secure the flags in place. The present invention also makes it more convenient to set-up, since no locking bracket assembly of threaded fasteners are required.




From the foregoing description of the preferred embodiments, it will be readily apparent that certain variations, modifications, or alterations may be made therein. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
