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

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.
