Abstract
An apparatus (12) for supporting a flag comprising a housing (26) having an opening (24) in a side face. A passage (30) extends trough housing (26). The housing (28) has a lower tubular part (40) that is mounted to the top of a flagpole (10). A cable (16) is attached to an arm (14). The cable extends from a winch (22) up through the flagpole and through the passage (30) in the housing (26). The cable is attached to the arm (14). In order to attach a flag to arm (14), winch (22) is operated to extend cable (16) and to lower arm (14) to the ground. Once a flag is attached to arm (14), the winch (22) is operated to retract the cable (16). This draws the arm (14) into the housing (26). Continued retraction of the cable (16) results in the arm (14) adopting an essentially horizontal position. The apparatus may rotate.
Description
FIELD OF THE INVENTION
The present invention relates to an apparatus for supporting flags, banners or the like. The apparatus may be mounted to the top of a flagpole or the like or it may form part of a flagpole or the like.
BACKGROUND OF THE INVENTION
Flagpoles are well known to all members of the community. The typical flagpole has an elongate pole extending vertically from the ground. A pulley is located at an upper end of the pole and a wire runs around the pulley. A flag is removably attached to the wire by personnel on the ground and the flag is then raised. Such flagpoles have a vertical edge of the flag attached to the wire, As a result, when conditions are not windy, the flag hangs limply against the pole.
In addition to hanging flags from flagpoles, it is becoming common to want to display advertising banners or commemorative banners from poles. With such banners it is especially undesirable to have the banner hang limply from the pole as the advertising or commemorative message is lost. In order to overcome this problem, poles may have horizontally extending arms fitted thereto such that the banner may hang from the horizontal arm. As the banner is suspended from a horizontal edge, it is fully displayed even in windless conditions.
Unfortunately, it can be difficult to hang banners or flags from such poles as the horizontal arms are typically fixed at the top of the pole or, if not at the top, quite some distance above the ground. In order to hang banners or flags on such poles, it is necessary to use ladders or cherry pickers to enable a person to reach the required height to hang the banner or flag. Alternatively, it is necessary to lower the pole to ground level. Either case is unsatisfactory in certain elements.
SUMMARY OF THE INVENTION
It is an objective the present invention to overcome or at least ameliorate some of the difficulties with the prior aft.
In a first aspect, the present invention provides an apparatus for supporting a flag, banner or the like comprising a housing having a passage therethrough, an arm, cable means attached to the arm and extending rough the passage wherein retracting the cable means through the housing causes the arm to be retracted into the housing and to be positioned in a predetermined orientation and releasing the cable means causes the arm to move from the predetermined orientation.
As used throughout the specification, the term “cable means” means extends to any cable, wire, rope or other generally filamentous material, irrespective of the particular construction thereof.
Preferably, releasing the cable means causes the arm to move out of the predetermined position under the influence of gravity.
The apparatus may further comprise mounting means for mounting the apparatus to a flagpole or the like. The mounting means may be used to mount the apparatus to the top of the flagpole or the like. The apparatus may be mounted to the top of the flagpole such that the apparatus can rotate.
The mounting means may suitably comprise a bush means having a flange at one end, the bush means being positioned such that it extends into a hollow part of a flagpole or the like and the flange rests on top of the flagpole, said bush means having an internal passage for receiving at least part of the housing.
Alternatively, the mounting means may comprise a bearing means affixed to a flagpole or the like, the bearing means supporting the housing.
In one particularly preferred embodiment, the passage in the housing includes an opening in a side face of the housing. This opening preferably has a lower edge and a wall of the passage extends upwardly and inwardly from the lower edge of the opening. In this fashion, the wall assists in guiding the arm to the desired predetermined orientation.
The arm preferably has a first shoulder positioned close to but away from an end thereof. When the arm is being retracted into the housing the shoulder may contact an engagement means to prevent fiber inward movement of the arm. Continued retraction of a cable means causes the arm to pivot upwardly about the engagement means into the predetermined position.
Preferably, the passage is shaped to allow the arm to pivot about the engagement means. In this regard, the passage may be shaped to provide clearance for movement of the portion of the arm that extends from the first shoulder to an inner end of the arm.
The first engagement means is suitably a first rod in the housing.
The arm preferably has a second shoulder opposed to the fist shoulder. In this embodiment, when the arm is in the predetermined orientation, the first and second shoulders may be positioned on opposite sides of the engagement means to thereby lock the arm against lateral movement when the arm is in the predetermined position.
In some instances, the opposed shoulders may be considered to define a neck region.
The housing may also include guide means around which the cable means can pass. The guide means is suitably a rotatable wheel, although a guide rod or arm may also be used.
The cable means should be sufficiently long to pass down the flagpole or the like and enable the arm to be lowered to essentially ground level. The banner or flag can then be attached to the arm and the cable means retracted to thereby raise the arm and position the arm on the predetermined position. To change a flag or banner, the cable means is unwound to thereby again lower the arm.
The predetermined orientation of the arm is generally horizontal. In some embodiments, the am may extend slightly upwardly and away from the housing when it is in the predetermined position. This assists in keeping the arm generally horizontal when the arm is carrying the weight of a flag, banner or the like.
In order to facilitate winding and unwinding of the cable means, a winch may be provided. The winch is suitably mounted within the flagpole for security purposes.
In another aspect, the present invention provides a flagpole or the like having an opening in a side surface thereof, a passageway extending from the opening and along the flagpole, an arm, a cable means attached to the arm, the cable means extending from the arm and through the passage wherein retraction of the cable means causes an end of the arm to move through the opening in the side surface of the flagpole or the like and to adopt a predetermined orientation and releasing the cable means causes the arm to move from the predetermined orientation.
In this aspect of the invention, the flagpole or the like may have a housing mounted therein. The housing may be generally similar to the housing as described with reference to the first aspect of the invention. Appropriate changes to the housing maybe made to account for the housing being mounted within the flagpole or the like.
Other features of the second aspect of the invention are suitably as described with reference to those features in the fist aspect of the invention.
The present invention also encompasses a flagpole or the like having the apparatus of the first aspect of the invention mounted thereto.
In embodiment where the apparatus can rotate about the flagpole or the like, the cable means is preferably provided with a swivel joint to avoid twisting of the cable means.
The arm may be suitably provided with means for attaching a flag or banner thereto. The arm may also be provided with fixing means to enable an extension arm to be fixed thereto. This will allow larger banners or flags to be suspended from the arm.
The predetermined orientation of the arm is preferably generally horizontal.

DETAILED DESCRIPTION OF THE DRAWINGS
It will be appreciated that the attached drawings are intended to illustrate a preferred embodiment of the present invention and the invention should not be considered to be limited to the embodiments shown therein.
Turing to
FIG. 1
, a hollow flagpole
10
is provided with the apparatus
12
in accordance with the invention. The apparatus
12
may be described as a rotating finial. The apparatus
12
will be described in more detail with reference to
FIGS. 2
to
4
hereunder. Suffice to say that apparatus
12
is rotatably mounted to the top of hollow flagpole
10
. The apparatus
12
includes an arm
14
. A cable means, in the form of a cable
16
is attached to one end of arm
14
. The cable
16
comprises an upper part
16
A and a lower part
16
B that are connected by a stainless steel swivel
20
. The swivel is provided to ensure that the cable
16
will not become twisted should the rotatable finial
12
rotate about the axis of the flagpole
10
in use.
A winch
22
having a removable handle
24
is mounted to the inside of the flagpole
10
. Winch
22
is used to unwind and wind up the cable
16
.
In order to attach a flag, banner or the like to arm
14
, the winch handle
24
is operated so that the cable
16
is unwound, which causes arm
14
to move from its upper position shown in
FIG. 1
to a position adjacent or near the ground. The arm
14
moves via position
14
B as shown in FIG.
1
. Once the arm has been positioned near the ground, a person can attach a flag or banner to the arm. The winch
22
is then wound up which causes cable
16
to lift the arm with attached flag or banner upwardly until the end
18
of arm
14
enters opening
24
. Further winding of the winch causes the arm
14
to move to the essentially horizontal position shown in FIG.
1
.
It will be appreciated that the above described manner of changing and fixing flags to the flagpole is much simpler than prior art methods which involved either putting a person up towards the top of the pole by a ladder or a cherry picker or dismantling or undoing the pole to lower it to essentially ground level.
Turning now to
FIGS. 2 and 3
, the apparatus
12
includes a housing
26
. The housing
26
has an opening
24
in one side face thereof. The opening
24
has a lower edge
28
.
The housing
26
also includes a passage
30
extending therethrough. The passage
30
opens at one end in opening
24
and opens at the other end at opening
32
.
As best seen from
FIG. 2
, the passage
30
has a wall
34
that extends upwardly and inwardly from lower edge
28
of opening
24
. The upper wall of passage located above lower wall
34
extends essentially horizontally or, in some embodiments, at a slight upwards angle to the horizontal. The upper wall is shown by reference numeral
36
in FIG.
2
.
The passage
30
also includes a chamber
38
that is located above the position of the end
18
of arm
14
when arm
14
is held in its predetermined orientation. The reason for the passage having this shape will be explained in more detail hereunder.
The lower part of housing
26
includes a downwardly extending tubular member
40
. Tubular member
40
may be formed integrally with the upper part of housing
26
or it may be formed as a separate part and a subsequently affixed to upper part of housing
26
. Downwardly extending member
40
defines part of passage
30
of the housing.
As best shown in
FIG. 3
, the apparatus may further include a bush
42
. Bush
42
includes a downwardly depending sleeve
44
that is sized to snugly fit within the inner diameter of hollow flagpole
10
. The bush
42
also includes an upper flange
46
, which upper flange rests on the upper part of flagpole
10
. The inner diameter of bush
42
is sized such that it can snugly accept downwardly extending tubular member
40
of housing
26
.
In use, bush
42
is permanently affixed to the upper part of flagpole
10
, for example, by the use of screws, bolts or the like. The screws, bolts or the like preferably pass along a chord of the flagpole
10
such that they nestle in recesses
48
formed in the tubular member
40
of housing
26
. In this manner, the screws, bolts or the like hold the housing
26
in position so that the housing
26
cannot be axially removed from the bush
42
. However, housing
26
is still able to rotate within the bush
42
.
It is preferred that the bush
42
is made from a self-lubricating polymeric material, such as Ertalon1fx. This is a polymeric material that incorporates graphite particles. The use of this material, or like materials, ensures that the housing
26
can freely rotate within the bush
42
.
The arm
14
has an end
18
to which the cable
16
is attached, or as shown in
FIG. 7
, from which the cable
16
extends. In the embodiment shown in
FIG. 2
the cable
16
passes through an opening in the end
18
of arm
14
and is connected to the arm
14
internally of the arm. The arm
14
is provided with a first shoulder
50
and a second shoulder
52
. Shoulders
50
,
52
are located a short distance away from end
18
of am
14
.
The housing
26
also includes a first rod
54
and a second rod
56
mounted within the housing. As best shown in
FIG. 2
, first rod
54
is sized such that it can be positioned within the neck portion defined between first shoulder
50
and second shoulder
52
. Second rod
56
is positioned as shown in FIG.
2
. Second rod
56
acts as a guide for the cable
16
.
In use of the invention shown in
FIGS. 1
to
3
, the cable
16
is initially unwound such that arm
14
is positioned close to the level of the ground. The banner and flag are attached to the arm and the cable
16
is then wound up. This raises the arm upwardly until end
18
of arm
14
begins to enter opening
24
in the side face of housing
26
. Continued retraction of the cable causes the end
18
of arm
14
to move into the housing and up along the wall
34
. As mentioned earlier, wall
34
extends upwardly and inwardly from the lower edge
28
of opening
24
. The wall
34
acts to guide the arm
14
as it is retracted into passage
30
of housing
26
.
The arm
14
continues to be retracted into the passage
30
by continued retraction of the cable until the first shoulder
50
engages with first rod
54
. Once the shoulder
50
engages with rod
54
, the arm
14
cannot be further retracted into passage
30
. However, continued force applied via retraction of cable
16
causes the arm
14
to pivot about the engagement between first shoulder
50
and first rod and first rod
54
. As a result, end
18
of arm
14
rotates downwardly and the end of arm
14
that is extending out of opening
24
pivots upwardly. Pivoting of the arm
14
continues until the arm
14
comes into contact with upper wall
36
of the passage
30
. At this time, second shoulder
52
is either in engagement with or in close abutment to first rod
54
. This thereby prevents lateral motion of the arm
14
. In other words, the arm
14
is effectively locked into position.
If the wind blows, the housing
26
may rotate in bush
42
.
In order to remove or change a flag or banner firm arm
14
, the cable
16
is unwound. As soon as the cable begins to unwind, the force of gravity causes the arm
14
to pivot about first rod
54
. This pivotal motion results in end
18
of arm
14
moving upwardly. In order to accommodate this movement (and the similar movement when the arm
14
is retracted into passage
30
) passage
30
is provided with chamber
38
above the end
18
as shown in FIG.
2
.
Once the cable
16
has been unwound sufficiently such that am
14
comes into contact with wall
34
, further unwinding of the cable
16
results in the arm
14
moving downwardly and out of the passage
30
. The arm can then be lowered to the ground.
FIG. 4
shows the arm
14
in ether detail. In particular,
FIG. 4
shows some constructional details of the arm
14
as well as the fitment of an optional extension arm thereto.
With reference to
FIG. 4
the arm
14
comprises a hollow tube
58
having a cap
60
fitted into one end. The other end has plug
62
fitted thereto. Plug
62
defines the first and second shoulders
50
,
52
as well as the end
18
of the arm
14
. Plug
62
has an opening
64
and a passage
66
extending therethrough, which passage and opening are sized to be able to receive the cable
16
. In order to affix the cable
16
to the plug
62
, the cable
16
is passed through passage
66
until a length of cable
16
extends therefrom. A swaging element
68
is then used to lock the cable
16
in place.
Although the end
18
of arm
14
shown in
FIG. 14
comprises plug
62
, it will be appreciated that end
18
may be integrally formed with the arm
14
. Similarly, the cable
16
does not necessarily have to pass or extend into the arm
14
. Indeed, the cable
16
may simply be attached to the end
18
of the arm
14
.
In order to facilitate fitment of banners or flags to the arm
14
, the arm may be provided with a stainless steel saddle
70
. Stainless steel saddle
70
may suitably be screwed or welded to the arm
14
.
The arm
14
is also provided with a button spring
72
which has a projection extending from a hole
74
in the arm
14
. The button spring
72
enables easy fitment of an extension arm
76
to the arm
14
. In particular, extension arm
76
is also provided with an opening
78
through which button spring
72
can fit when the opening
78
is positioned over the button spring
72
. The button spring
72
may have an external profile that enables easy fitment.
The present invention enables especially convenient changing of flags, banners or the like, The apparatus enables the support arm for holding the flag to be securely positioned in a generally horizontal orientation. Engagement between the arm
14
and the upper wall
36
of the passage maintains the arm
14
in the horizontal orientation. Moreover, engagement between the first and second shoulders
50
,
52
and the first rod
54
locks the arm
14
into a fixed lateral position.
The second rod
56
is positioned as shown in
FIG. 2
in order to ensure that a suitable turning moment is applied by retraction of the cable once the first shoulder
50
contacts the first rod
54
.
The embodiments shown in
FIGS. 1
to
3
relate to a rotating finial that is positioned on top of a flagpole. However, it will be appreciated that the housing
26
may be mounted to an intermediate portion of a flagpole. In this arrangement, it is not necessary to have the downwardly extending tubular member
40
as part of the housing
26
. Furthermore, it will be necessary to provide an opening in the outer surface of the flagpole that is generally coincident with the opening
24
in the side surface of the housing. It may also be appropriate to form the housing such that it is generally cylindrical in this embodiment so that it neatly fits inside cylindrical flagpoles. It will also be appreciated that similar apparatus may be integrally formed with the flagpole rather than having a separate housing that is mounted to the flagpole. However, the use of a separate housing has the advantage that it can be retrofitted to existing flagpoles.
FIG. 5
shows a cross-sectional view of an alternative arm construction. The arm of
FIG. 5
has a generally similar construction to the arm of FIG.
4
and like features in
FIG. 5
have been given the same reference numeral as the equivalent features in FIG.
4
. Those feature need not be discussed further.
The arm of
FIG. 5
differs from that in
FIG. 4
in that a compression spring
80
is fitted to abut against end
82
of plug
62
. A washer
84
is placed against the opposite end of compression spring
80
and, in conjunction with swaging element
68
assists in holding the cable in place.
The use of the compression spring
84
in the arm of
FIG. 5
assists in lowering impact forces caused by retracting the cable, thereby potentially increasing the useful life of the arm.
FIGS. 6 and 7
show a housing and apparatus that is generally similar to that shown in
FIGS. 2 and 3
. Features in
FIGS. 6 and 7
that are common with features in
FIGS. 2 and 3
have been given the same reference numerals as those in
FIGS. 2 and 3
and need not be described further.
The main difference between the embodiment of
FIGS. 2 and 3
and the embodiment of
FIGS. 6 and 7
is that the embodiment of
FIGS. 6 and 7
includes a rotatable guide wheel
90
mounted on a pin or axle
92
to guide the cable
16
. The guide wheel
90
replaces the second rod
56
and acts to reduce friction on the cable
16
during retraction or extension of the cable
16
.
FIG. 8
shows the apparatus of
FIGS. 6 and 7
mounted to a flagpole. The features of
FIG. 8
are similar to those of FIG.
1
and like reference numerals have been used on both Figures. The description of
FIG. 1
is equally applicable to FIG.
8
and further description of
FIG. 8
is not required.
The housing of
FIGS. 2 and 3
or
6
and
7
may be made from two separate pieces mat are joined together by screws or other suitable fasteners. Screw holes
100
may be provided for that purpose.
FIGS. 9 and 10
shows another embodiment of the present invention. In
FIGS. 9 and 10
, features that are common with the embodiment of
FIGS. 1
to
4
or with the embodiment of
FIGS. 5
to
8
are denoted by the same reference numeral.
In the embodiment of
FIGS. 9 and 10
, the arm
14
is not provided with shoulders
50
,
52
, as shown in
FIGS. 1
to
8
. Housing
26
also does not have pin
54
.
In the embodiment of
FIGS. 9 and 10
, arm
14
has an essentially cylindrical side surface and a curved or rounded end
101
. When the cable
16
is fully retracted, end
101
extends into chamber extension
102
. Tension on cable
16
and contact between the side wall of arm
14
and top
104
of passage
30
results in the arm
14
being held in place. The arm can be lowered in a similar fashion to that described for the embodiments of
FIGS. 1
to
8
.
FIGS. 11
to
16
who a further embodiment of the present invention. A number of the features of the embodiment shown in
FIGS. 11
to
16
are common to the embodiments shown in
FIGS. 1
to
10
. For convenience, like features in
FIGS. 11
to
16
will be denoted by the same reference numberal as used for the corresponding features in
FIGS. 1
to
10
, but with the addition of a prime (′)

190
includes opposed keyways
192
,
193
that receive projections
194
,
195
that are formed on the side of the upper part of tubular member
40
′. In use, if the apparatus
12
′ rotates, foe example, as caused by wind blowing a flag, the upper bush
190
rotates on the upper flange
46
′ of lower bush
40
′. The frictional forces acting on the apparatus can be reduced by manufacturing the upper and lower bushes from suitable plastics materials, especially from a self-lubricating polymer. It will be appreciated that the mounting of the apparatus
12
′ to the flagpole
10
′ is essentially identical to the mounting of the apparatus
12
to the flagpole
10
, as described with reference to
FIGS. 1-10
, except for the inclusion of upper bush
190
.
The arm
14
′ has an end
18
′ to which the cable
16
′ is attached, or as shown in
FIG. 15
, from which the cable
16
′ extends. In the embodiment shown in
FIG. 15
the cable
16
′ passes through an opening in the end
18
′ of arm
14
′ and is connected to the arm
14
′ internally of the arm. Unlike the arm
14
of
FIG. 4
, the arm
14
′ is not provided with first and second shoulders.
The housing
26
′ also includes a first rotating wheel
90
′ which acts as a guide for the cable
16
. A second rotating wheel
91
is alos provided to assist in guiding the cable
16
′ and ensure that the cable
16
′ does not rub on the inner wall of passage
30
′. Wheels
90
′ and
91
are mounted on respective axles
193
,
194
.
In use of the invention shown in
FIGS. 11
to
16
, the cable
16
′ is initially unwound such that arm
14
′ is positioned close to the level of the ground. The banner or flag is attached to the arm and the cable
16
′ is then wound up. This raises the arm upwardly until end
18
′ of arm
14
′ begins to enter opening
24
′ in the side face of housing
26
′. Continued retraction of the cable causes the end
18
′ of arm
14
′ to move into the housing and up along the wall
34
′. As mentioned earlier, wall
34
′ extends upwardly and inwardly from the lower portion of opening
24
′. The wall
34
′ acts to guide the arm
14
′ as it is retracted into passage
30
′ of housing
26
′.
The arm
14
′ continues to be retracted into the passage
30
′ by continued reaction of the cable. Eventually, the arm
14
′ pivots on point
197
where wall
34
′ meets horizontal lower wall
198
. As a result, end
18
′ of arm
14
′ rotates downwardly and the end of arm
14
′ that is extending out of opening
24
′ pivots upwardly. Pivoting of the arm
14
′ continues until the arm
14
′ comes into contact with upper wall
36
′ of the passage
30
′. The arm is held in place against movement out of opening
24
′ by the tension applied to cable
16
′.
