Description

PORTABLE BARRIER ARM FOR MANUAL TRAFFIC CONTROL

RELATED APPLICATIONS

This application derives priority from New Zealand patent application numbers 733660 and 738477 incorporated herein by reference.

TECHNICAL FIELD

Described herein is a portable barrier arm for manual traffic control. More specifically, a traffic control barrier comprising two paddles perpendicular (offset or out of phase approximately 90 degrees) to each other for controlling vehicle movement during emergencies, road construction, public events, or other activities.

BACKGROUND ART

It is common practice to employ flag men to control traffic flow in highway construction zones. These individuals manipulate passive signs which bear short, lettered, instruction messages, i.e., STOP or GO. The instructions are usually provided on opposite planar sides of a sign board, and the sign board is typically mounted on the top of a pole, the opposite end of the pole being positioned on the ground. The instruction transmitted to an approaching motorist is thus changeable by simply rotating the pole so that the appropriate message is presented to approaching traffic.

For example, US Patent No. 6,134,819 discloses a portable illuminated traffic signal device. In particular, a traffic signing device that includes a strobe light directed upon a portable traffic sign for alerting distant motorists of an upcoming traffic condition and for enhancing readability of the traffic sign. The signalling device includes a rotatable sign assembly releasably attached to a primary shaft suitable for holding by a road construction worker. The sign assembly includes a handle which cooperates with a channel within the primary shaft whereby the sign can be rotated to discrete, locked positions without repositioning the primary shaft or strobe light. Thus, either side of a sign may be displayed to oncoming traffic while a worker's eyes are always shielded from the strobe light.

US Patent No. 2015/0121731 discloses a traffic control paddle with extendable rod handle paddle having a display sign having two opposing display sides; a unitary handle comprising a plurality of telescoping tubes, the handle having opposing ends, the first end reversibly attachable to the display sign, the handle adjustable between a fully extended position and a plurality of collapsed positions; a handle adjustment means comprising a twist lock mechanism to convert the paddle between discrete positions; one or more LED lights attached to the handle; and a base plate attached to the second end of the handle.

US Patent No. 9,305,472 discloses an illuminated traffic control paddle that includes a head with a

2018205085 10 Jul 2018 handle and a head having two sides. The head has a perimeter, a face inset within the perimeter, a surface on the face carrying literal indicia, and an upstanding lip extending around the perimeter and projecting above the face. Two spaced-apart light-emitting diodes in the face are seated in annular projections. The handle carries batteries and a switch to provide power to the light-emitting diodes. The light-emitting diodes are spaced above and below the literal indicia on the face and are programmed to blink.

However, a disadvantage of the above traffic control paddles is that they do not provide a physical barrier across a lane in the direct line of sight of a driver. A barrier being across the lane prevents a vehicle from driving through or missing the traffic control paddle all together.

US Patent No. 4,065,104 discloses a portable barricade for use at school crossings, and the like, has a frame mounted on wheels and is provided with at least one lamp assembly for warning parties approaching the barricade of the presence of a potentially hazardous condition. Attached to the frame is a brake which permits selective retention of the barricade in a desired position in a crosswalk or similar location for a predetermined length of time. Once the need for the barricade at the particular location has ended, the brake may be released and the frame moved to another location.

However, a disadvantage of the above barricade is that it is bulky and designed to close off a road for substantial period of time without allowing vehicles to easily access in the interim. This is because the entire barricade has to be wheeled away (once the brakes have been released) in order to allow vehicles in the interim to pass through the lane.

Crossing guards play a vitally important role in school safety and traffic management. Traditional crossing guards stand watch and operate a horizontal traffic control paddle comprising a barrier arm that is removably attached to a permanently mounted vertical pole or the like. In order to control the movement of traffic across a lane, the crossing guard walks out onto the lane thereby swinging out the barrier arm into the line of traffic. However, a disadvantage of this apparatus and barrier operation is that it exposes the crossing guard to live traffic when they walk out into the lane.

It should be appreciated from the above that there is a need for an apparatus for manual, automated and/or remotely operated traffic control that provides a temporary physical barrier for traffic management at road sites that avoids the need for flag men or crossing guards to walk out onto live traffic. Furthermore, it would be advantageous if the above can be achieved with a simplified design requiring minimal componentry or to at least provide the public with a useful choice.

Further aspects and advantages of the process and product will become apparent from the ensuing description that is given by way of example only.

SUMMARY

Described herein is a portable barrier arm for manual traffic control. More specifically, a traffic control barrier comprising two paddles perpendicular (offset or out of phase approximately 90 degrees) to each other for controlling vehicle movement during emergencies, road construction, public events, or other 5 activities.

In a first aspect there is provided a portable barrier arm for manual traffic control comprising:

an elongate pole member having a top end and a bottom end, the top end having at least one bearing mechanically coupled to the elongate pole member for axial rotation of the pole member in at least one direction;

the bottom end of the pole base mounted to a base member;

a barrier arm linked to the top end of the elongate pole member via the bearing, and having a first paddle member at a distal end with indicia thereon;

an elongate pole extension member attached to the barrier arm, and having a second paddle member with indicia thereon mounted on the elongate pole extension member; and a locking assembly for selectively locking the barrier arm in and releasing the barrier arm for rotation from a stationary position, wherein the barrier arm rotates from a stationary inwards position to an outwards position across a road lane when the locking assembly is released from the stationary position, and wherein the first and second paddle members are mounted perpendicular (offset or out of phase approximately 90 degrees to each other) and the second paddle member is turned edge on and thus the indicia thereon is not visible to a pedestrian and/or driver of a vehicle on the road lane.

In a second aspect there is provided a portable barrier arm for manual traffic control comprising:

an elongate pole member having a top end and a bottom end, each end having at least one bearing mechanically coupled to the elongate pole member for axial rotation of the pole member in at least one direction;

a base linked to the bottom end of the elongate pole via the bearing;

an elongate pole extension member attached to the barrier arm, and having a second paddle member with indicia thereon mounted on the elongate pole extension member; and a locking assembly for selectively locking the barrier arm in and releasing the barrier arm for rotation from a stationary position, wherein the barrier arm rotates from a stationary inwards position to an outwards position across a

2018205085 10 Jul 2018 road lane when the locking assembly is released from the stationary position, and wherein the first and second paddle members are mounted perpendicular (offset or out of phase approximately 90 degrees) to each other and the second paddle member is turned edge on and thus the indicia thereon is not visible to a pedestrian and/or driver of a vehicle on the road lane.

Ina third aspect there is provided an automated or remotely operated portable barrier arm for manual traffic control comprising:

an elongate pole member having a top end and a bottom end, the elongate pole member being configured for axial rotation in at least one direction;

a base linked to the bottom end of the elongate pole for housing a motor and electronic componentry;

a barrier arm having a first paddle member at a distal end with indicia thereon attached to the elongate pole member;

a second paddle member with indicia thereon mounted to the top end of the elongate pole member perpendicular (offset or out of phase approximately 90 degrees) relative to the first paddle member;

wherein the barrier arm rotates from a stationary inwards position to an outwards position when the barrier arm is automatically or remotely operated such that the barrier arm is turned out across a road lane and the second paddle member is turned edge on and thus the indicia thereon is not visible to a pedestrian and/or driver of a vehicle on the road lane.

Advantages of the above are that the portable barrier arm is easy to operate and does not take long to set up. The barrier keeps the operator out of live traffic as it avoids the need for the operator to walk out onto the road. The barrier is visible from some considerable distance away and being at eye level and in direct line of sight. Thus, providing a physical barrier across the lane such that a driver can not miss the barrier or drive through the lane and hence meeting Code of Practice temporary Traffic Management (COPTTM) standards for long-term worksites where MTCS are deemed Inappropriate. In a normal prior art Stop/Go operation, the Manual Traffic Control (MTC) and paddle is difficult to identify amongst the numerous collection of orange cones and equipment on a road site. The configuration where there is no indicia on the reverse side of the paddles such as 'GO' means that drivers are not looking up the road at the reverse side of the other operator's paddle. The barrier also avoids the problem of a fatigued operator continuously having their paddle on 'Go', and only the apparatus is required to be manually operated when traffic is required to be stopped. The barrier is portable which means that it can easily be relocated/transported to provide temporary traffic management option at road work sites and the like. For example, the base is lightweight and the poles and paddles are detachable or removable from the base for compact storage. Also, the use of a removable cone that can easily be integrated into the elongate pole meets temporary traffic management regulations. For the automated and/or remotely controlled traffic control system, there is increased safety and economic benefits as either an operator is

2018205085 10 Jul 2018 out of live traffic (operating via a remote) or not required as per a fully automated system.

DETAILED DESCRIPTION

As noted above, described herein is a portable barrier arm for manual traffic control. More specifically, a

2018205085 10 Jul 2018 traffic control barrier comprising two paddles perpendicular (offset or out of phase approximately 90 degrees) to each other for controlling vehicle movement during emergencies, road construction, public events, or other activities.

For the purposes of this specification, the term 'about' or 'approximately' and grammatical variations thereof mean a quantity, level, degree, value, number, frequency, percentage, dimension, size, amount, weight or length that varies by as much as 30, 25, 20,15,10, 9, 8, 7, 6, 5, 4, 3, 2, or 1% to a reference quantity, level, degree, value, number, frequency, percentage, dimension, size, amount, weight or length.

The term 'substantially' or grammatical variations thereof refers to at least about 50%, for example 75%, 10 85%, 95% or 98%.

The term 'comprise¹ and grammatical variations thereof shall have an inclusive meaning - i.e. that it will be taken to mean an inclusion of not only the listed components it directly references, but also other non-specified components or elements.

The term 'manual traffic control' or grammatical variations thereof should be understood to mean providing road traffic control that involves directing vehicular and/or pedestrians or providing a physical barrier around a school zone, construction zone, accident or other road disruption or the like, thus ensuring the safety of emergency response teams, construction workers and the general public.

The abbreviation MTC should be understood to be a person employed by a contractor to manage traffic through a worksite and may be used for situations that include: stopping traffic to avoid a hazard, allowing traffic from opposite directions to use one lane alternately (alternating flow), stopping all road traffic to allow construction traffic to cross or for blasting, or tree work, slowing traffic where they need to travel very slowly, e.g. over new seal or in poor visibility, and giving road users verbal instructions or directions.

The term 'paddle' or grammatical variations thereof should be understood to mean a paddle sign with pole for displaying indicia for traffic and pedestrian safety concerns.

The term 'indicia' or grammatical variations thereof refers to signs, indications such as 'STOP', 'GO', 'SLOW' or the like on the paddles.

The terms 'automated' and 'automatically' or other grammatical variations thereof should be understood to mean a traffic control system that emulates the actions and decisions of flagmen to control and direct vehicular and/or pedestrian traffic. Such a control system may utilise a computer, sensors, video cameras, radio communications and the like.

The term 'remotely operated' or grammatical variations thereof should be understood to mean a traffic control system that utilises a remote control, radio communication or the like to control and direct vehicular and/or pedestrian traffic.

2018205085 10 Jul 2018 an elongate pole member having a top end and a bottom end, the top end having at least one bearing mechanically coupled to the elongate pole member for axial rotation of the pole member in at least one direction;

the bottom end of the pole base mounted to a base member;

an elongate pole extension member attached to the barrier arm, and having a second paddle member with indicia thereon mounted on the elongate pole extension member; and a locking assembly for selectively locking the barrier arm in and releasing the barrier arm for rotation from a stationary position, wherein the barrier arm rotates from a stationary inwards position to an outwards position across a road lane when the locking assembly is released from the stationary position, and wherein the first and second paddle members are mounted perpendicular (offset or out of phase approximately 90 degrees to each other) and the second paddle member is turned edge on and thus the 15 indicia thereon is not visible to a pedestrian and/or driver of a vehicle on the road lane.

The base may be a square plate and provide support and weight to anchor the barrier apparatus.

The base may also include fixing elements to retain a road cone that is mounted thereon the elongate pole member.

In one embodiment, the base may optionally include hinged side members. In this way, the base can be 20 folded away for compact storage. Also, sand bags and the like may be rested on the hinged side members to provide additional weight and prevent the apparatus from toppling over in adverse weather conditions.

The elongate pole member or mast may comprise a steel tube that links and/or fixedly retains the base to the barrier arm. As above, a road cone maybe inserted over the elongate pole member and thus 25 covers the elongate pole member. In this way, the apparatus meets regulations at temporary traffic management (TTM) sites. It should be appreciated by those skilled in the art that the cone may be replaced with other housings on non-TTM sites or may not have any housing.

In a preferred embodiment, the apparatus may include one top bearing that is manufactured out of nylon and mounted above a cone top to provide axial rotation of the barrier arm.

In alternative embodiments, the apparatus may also include a bottom bearing mechanically coupled to the bottom end of the elongate pole member for axial rotation of the pole member in at least one direction.

In further alternative embodiments, the bearing may include a sliding cambered face to urge movement of the barrier arm in an inward and outwards position. The bearing may be configured to allow at least

2018205085 10 Jul 2018

90° of movement of the barrier arm.

The locking assembly may comprise a locking pin and a latch. The gate latch style pin may slide over bearing tube sides. In this way, when the barrier arm rotates and when the barrier arm reaches a full open or closed position, the pin head may slot into a predrilled hole or opening in the bearing tube to lock further arm movement. The head of the locking pin may be urged into the hole by a spring or other such biasing means.

The latch may include a right angle external ending to allow the pin to be withdrawn from the hole against bias by a user.

The barrier arm may extend across the elongate pole member or mast, such that the weight of the arm may be balanced over the top of the mast. In this way, if the user releases the arm, the arm will balance and not drop vertically or at least may not drop either side of the mast.

The barrier arm may be telescopic. In this way, the barrier arm may be extended and/or retracted form the centre to full width of the lane or may be used to block off roadways of varying widths (1750 mm 4000) and keep components clear of the curbside if necessary.

The road ending of the barrier arm may extend out into the roadway when the paddle or sign is out and may comprise usual markings along the shaft and standard indicia such as a 'STOP' sign at the shaft distal end.

The road ending of the barrier arm may be manufactured out of rectangular hollow section steel (RHS). However, this should not be seen as a limitation on the present invention. For example, the barrier arm may be manufactured out of round pole section steel, plastic, composite material or the like.

The pavement ending of the barrier arm may be dimensioned so that it is long enough for a user to comfortably grasp and manoeuvre when the barrier arm is rotated outwards onto the roadway.

The pavement ending of the barrier arm may include a counterweight at a distal end so as to allow for a shorter shaft length than the road ending barrier arm as described above. Furthermore, the counterweight helps to balance the arm over the mast.

The apparatus may include an elongate pole extension member attached to the barrier arm, and having a second paddle member with indicia 'GO' thereon mounted on the elongate pole extension member.

The apparatus configured in this way may meet temporary traffic management (TTM) site requirements.

For TTM applications, the face of the first paddle member with indicia 'STOP' may be mounted substantially perpendicular or at approximately 90° to the face of the second paddle member with indicia 'GO' such that, when the barrier arm is in a closed position kerbside, the second paddle member with 'GO' indicia faces the on-coming traffic. In other embodiments, the second paddle member may be removed when not used.

2018205085 10 Jul 2018 an elongate pole member having a top end and a bottom end, each end having at least one bearing mechanically coupled to the elongate pole member for axial rotation of the pole member in at least one direction;

a base linked to the bottom end of the elongate pole via the bearing;

an elongate pole extension member attached to the barrier arm, and having a second paddle member with indicia thereon mounted on the elongate pole extension member; and a locking assembly for selectively locking the barrier arm in and releasing the barrier arm for rotation from a stationary position, wherein the barrier arm rotates from a stationary inwards position to an outwards position across a road lane when the locking assembly is released from the stationary position, and wherein the first and second paddle members are mounted perpendicular (offset or out of phase approximately 90 degrees) to each other and the second paddle member is turned edge on and thus the 15 indicia thereon is not visible to a pedestrian and/or driver of a vehicle on the road lane.

In a third aspect there is provided an automated or remotely operated portable barrier arm for manual traffic control comprising:

The base may be a weather proof housing or rigid casing that encloses and protects additional componentry or equipment.

The base may be of a sufficient weight to anchor the barrier apparatus and support the weight of the barrier arm, yet still be of an optimal weight for ease of portability. It is envisaged the base may be between approximately 20 - 40 kgs.

2018205085 10 Jul 2018

The base may also include a stand or feet members to raise the base above ground level thereby providing additional protection from the elements. Also, the stand or feet members may provide additional weight and stability to prevent the apparatus from toppling over in adverse weather conditions.

In one embodiment, the base may optionally include handle side members. In this way, the base can be easily lifted up and transported for portability.

The battery may be housed in the base comprising an in-built rechargeable battery with up to 14 hours of continuous operation. In this way, no external power source is required. It is envisaged that the battery may be a rechargeable lithium-ion battery or equivalent with high energy density, minimal 10 memory effect and low self-discharge.

The apparatus may comprise an actuator for moving and controlling the barrier arm. In one embodiment the actuator is an LA12 manufactured by Linak™ of the type 12XX00-2XXX12XX having a 12V motor, 4 mm spindle pitch, 300 N thrust, 150 N self-lock, typical speed of 16-27 mm/s depending on load, stroke length of 40-130 mm and operating between 1.75 - 2.5 amps. An actuator provides a practical and cost15 effective alternative to small-scale traditional hydraulic and pneumatic systems. The LA 12 is ideal for applications requiring short linear movements. However, this should not be seen as a limitation on the embodiments envisaged for this invention as conceivably hydraulic, pneumatic and other types of systems could be used with this apparatus.

The actuator may have permanent magnetic motor that operates between 12-24 V DC having a gear ratio able to move the barrier arm and counteract wind resistance during rotation of the barrier arm.

The apparatus may comprise electronic circuitry and software program protocols developed by Lodar™ radio controls. For example, wiring and circuitry utilised from Lodar™ 92 and 93 series, field transistor (FET) receivers.

The apparatus may use a remote or radio control transmitter and receiver system that allows an operator to be located at least 600 metres away from traffic, thereby providing a safe work site environment. A remote control battery pack with alkaline manganese batteries (3-9 Volts) may provide up to 200 hours of continuous and/or intermittent operation.

In one embodiment, the apparatus may use a Lodar™ radio transmitting unit with a single press mechanism configured to operate within a temperature range of -20°C to 55°C with an output of 1 mW 30 and IP rating between 55-67 and having a range of 60 -600 metres with an external aerial. In this way, a sole operator can manage traffic through the worksite with repeated presses of a single button on the remote/radio control unit. Furthermore, this allows for labour saving as only one operator is required to control the traffic flow at both ends of the work zone.

The receiving unit may be a Lodar™ 15 amp field-effect transistor (FET) for multiple switching functionality having a complementary range of 60 - 600 metres.

2018205085 10 Jul 2018

The apparatus may use a camera system. In this way, a sole operator can manage traffic through the worksite without requiring a line of site between the base units. As above, this allows for labour saving as only one operator is required to control the traffic flow at both ends of the work zone.

The above remote/radio control system should not be seen as a limitation on the embodiments envisaged for this invention. Other control systems may be conceivably used with this invention. For example, the use of camera(s), sensor(s), wireless communications and other integrated technologies may allow a fully automated system of operation with vehicle and/or pedestrian detection system that does not require an operator to activate the barrier.

The elongate pole member or mast may comprise a light weight steel or aluminium tube that links and/or fixedly retains the base to the barrier arm. The mast may include a 300 mm horizontal T-section for connection of the barrier arm to the mast. The barrier arm may comprise a hollow flexible sleeve for sliding engagement onto a fixed bracket that may be attached to the rotating elongate pole member.

A locking fastener may comprise a locking pin clip to removably retain the hollow sleeve of the barrier arm onto the fixed bracket.

The elongate pole member or mast may be hollow for sliding engagement with a shaft of the motor. As above, a locking fastener may comprise a locking pin clip to removably retain the elongate pole member onto the motor shaft and provide the drive mechanism for axial rotation of the mast.

As above, the second paddle member may comprise either a 'GO' (RP41) or a 'SLOW' (RP42) sign that maybe inserted over or removable mounted to the elongate pole member. The paddle may be used in combination with the following signs in advance: T1A/B Road Works, TA2 manual traffic control, and TGI speed limit -Temporary signs (30 km/h or less). In this way, the apparatus meets regulations i.e. code of practice for temporary traffic management (COPTTM) sites.

The barrier arm may be manufactured out of lightweight plastic, fibreglass, or the like, such that the weight of the arm may be minimised. However, this should not be seen as a limitation on the present invention. For example, the barrier arm may be manufactured out of round or rectangular hollow section (RHS) pole section steel or the like. In this way, the moment of force of the arm may be reduced and prevent the apparatus from toppling over or causing undue strain on the motor and gearing mechanism during axial rotation.

The road ending of the barrier arm may extend out into the roadway when the paddle or sign is out and may comprise usual markings along the shaft and standard indicia such as a 'STOP' (RP4) sign at the shaft distal end.

Furthermore, the apparatus that includes a barrier that extends out into the roadway may enhance vehicular compliance at the 'STOP' sign by creating a physical barrier. In this way, the safety of MTC and other people onsite is increased whilst complying with long-term worksite regulations (COPTTM) where 35 the use of MTCs are regarded as inappropriate and stop/go operations must not be used where two-way

2018205085 10 Jul 2018 traffic flow can be maintained past a worksite. According to guidelines, the recommended devices for traffic management at these worksites are portable traffic signals or barrier arm systems as described herein.

The axial rotation of the elongate pole or mast may permit movement of the barrier arm in a horizontal plane. As noted above, the 'STOP' and 'GO signs or paddles may be separate and mounted 90 degrees out of phase with each other i.e. the face of the first paddle member with indicia 'STOP' may be mounted substantially perpendicular or at approximately 90° to the face of the second paddle member with indicia 'GO' such that, when the barrier arm is in a closed or first position kerbside (the arm may be turned to be aligned with the road edge and may not be visible to on-coming traffic), the second paddle member with 'GO' indicia faces the on-coming traffic. In a second position, where the barrier arm may be turned out across the road lane which presents the barrier arm with the 'STOP' sign to the driver, the second paddle member with 'GO' sign is turned edge on to the driver and hence is not visible. An advantage of this configuration is that the 'STOP' / 'GO signs are prevented from both showing at any one time to avoid confusion.

Further advantages of the above may include:

• Improved safety for a user as at no stage does the user need to step out on the pavement to operate the barrier arm;

• The barrier arm has neutral weight balance provided by counterweight. Therefore, minimal strength and balance needed to operate and hence suitable for use for children at school crossings;

• The apparatus is portable without the requirement of permanently installed mounting posts which means that it can easily be relocated to provide temporary traffic management option at road work sites and the like;

• The barrier arm is visible from some considerable distance away and being at eye level and in direct line of sight. Thus, providing a physical barrier across the lane such that a driver can not miss the barrier or drive through the lane and hence meeting COPTTM standards for long-term worksites where MTCS are deemed inappropriate;

• The configuration of the barrier arm also avoids the problem of a fatigued operator continuously having their paddle on 'Go', and only required to be manually operated when traffic is required to be stopped;

• The use of a removable cone that can easily be integrated into the elongate pole meets temporary traffic management (TTM) regulations;

• An apparatus with a base that is is lightweight where the poles and paddles are detachable or removable from the base/motor unit allows for compact storage.

• For the automated and/or remotely controlled traffic control system, there is increased safety

2018205085 10 Jul 2018 and economic benefits as either an operator is out of live traffic (operating via a remote) or not required as per a fully automated system with vehicle detection.

The embodiments described above may also be said broadly to consist of the parts, elements and features referred to or indicated in the specification of the application, individually or collectively, and any or all combinations of any two or more said parts, elements or features.

Further, where specific integers are mentioned herein which have known equivalents in the art to which the embodiments relate, such known equivalents are deemed to be incorporated herein as if individually set forth.

WORKING EXAMPLES

The above described apparatus and use is now described by reference to specific examples.

EXAMPLE 1

With reference to Figures 1, 2, and 3, an assembled portable barrier arm apparatus 1 with road cone 2 inserted through an elongate pole 3 (best seen in Figure 4) and barrier arm 4 in the outwards stop position is shown.

The base 5 is a metal square plate that provides support and weight to anchor the barrier arm apparatus (best seen in Figure 4). The base 5 includes fixing elements 6 to fixedly retain a road cone 2 that is inserted over the elongate pole member 3 to act as a cover to satisfy regulations at temporary traffic management (TTM) sites.

A top bearing 7 (best seen in Figures 4 and 5) is mechanically coupled to the top end of the elongate pole member 3 for axial rotation of the pole member 3. The bearing 7 is manufactured out of nylon and is configured to allow at least 90° of movement of the barrier arm 4.

As shown in Figure 6, the locking assembly 7 comprises a locking pin and a latch. When the barrier arm 4 rotates and when the barrier arm 4 reaches a full open or closed position, the pin head 8 slots into a predrilled hole or opening 9 of the elongate pole 3 to lock further arm 4 movement. The head 8 of the locking pin is urged into the hole 9 by a spring. The latch includes a right angle extrusion to allow the pin to be withdrawn from the hole 9 against bias by a user.

As shown in Figures 1, 2, and 3 the barrier arm 4 extends across the elongate pole member 3, such that the weight of the arm 4 is balanced over the top of the pole member 3. The road ending 10 of the barrier arm 4 extends out into the roadway when the 'STOP' paddle or sign is out at the shaft distal end.

The pavement ending 11 of the barrier arm 4 is dimensioned so that it is long enough for a user to comfortably grasp and manoeuvre when the barrier arm 4 is rotated outwards onto the roadway. Also,

2018205085 10 Jul 2018 the pavement ending 11 of the barrier arm 4 includes a counterweight 18 at a distal end to provide a neutral balance of the arm 4 over the elongate pole member 3.

A second paddle member or 'GO' sign is mounted on the elongate pole extension member 3 to meet temporary traffic management (TTM) site requirements. For TTM applications, the face of the first paddle member or 'STOP' sign is mounted substantially perpendicular or at approximately 90°to the face of the second paddle member or 'GO' sign such that, when the barrier arm 4 is in a closed position kerbside, the second paddle member or 'GO' sign faces the on-coming traffic.

EXAMPLE 2

With reference to Figure 7, the portable barrier arm apparatus 1 is designed to operate as follows. There are predominately two positions for the barrier arm 4 i.e. inward or outwards.

The base 4 of the portable barrier arm apparatus 1 is positioned on the pavement kerbside with barrier arm 4 parallel to the road traffic direction in a first position which allows traffic to pass through the roadway. In this first position, a driver will sight the second paddle member or 'GO' sign which is mounted on the elongate pole extension member 3. A user stands at point X or Y. In order to stop traffic, a user unpins the gate latch about the pavement area and rotates the barrier arm 4 90° such that barrier arm 4 provides a physical barrier on to the roadway while exposing the face of the first paddle member or 'STOP' sign at the shaft distal end to the driver (i.e. second position). The gate latch engages a second locating hole to retain the barrier arm 4 in an outward position. Simultaneously, the second paddle member or 'GO' sign which is mounted on the elongate pole extension member 3 perpendicular to the first paddle member or 'STOP' sign is rotated out of view of the driver.

To allow traffic back through the roadway, the order of operation as described above is reversed such that the barrier arm 4 is parallel to the road traffic direction in a first position.

EXAMPLE 3

With reference to Figures 8 and 9, an assembled remotely operated portable barrier arm apparatus 1 is shown in the 'STOP' position (left side of Figures 8 & 9) and 'GO' position respectively (right side of Figures 8 & 9).

The base 5 is a weatherproof housing or rigid casing that encloses and protects additional componentry and equipment (not shown) such as electronics, battery, receiver, and motor. The base 5 is of a sufficient weight to anchor the barrier apparatus 1 and is approximately 30 kgs. As shown, the base 5 includes a stand 12 with feet member 13 to elevate the base above ground level for additional protection from the elements.

As above, the battery (not shown) is housed in the base 5 and is a rechargeable lithium-ion battery with

2018205085 10 Jul 2018 at least 14 hours of continuous operation with an output of 1 mW and IP rating between 55-67. A radio control transmitter (not shown) and receiver (not shown) are housed in the base 5 that allows an operator to be located away from traffic. In particular, the radio control transmitter is a Lodar™ radio transmitting unit with a single press mechanism configured to operate within a temperature range of 5 20°C to 55°C having a range of 60 - 600 metres with an output of 1 mW and IP rating between 55-67. A sole operator can manage traffic through the worksite with repeated presses of a single button on the radio control unit to activate the barrier arm 4.

The receiving unit is a Lodar™ 15 amp field-effect transistor (FET) for multiple switching functionality having a complementary range of 60 -600 metres.

The elongate pole member or mast 3 is a lightweight aluminium tube that links and fixedly retains the base 5 to the barrier arm 4. The mast 3 includes a 100 mm horizontal T-section for connection of the barrier arm 4 to the mast 3. The barrier arm 4 is a telescopic hollow aluminium box section with a flexible sleeve 14 for sliding engagement onto a fixed bracket 15 that is attached to the rotating elongate pole member 3.

A locking fastener (not shown) comprises a locking pin clip to removably retain the hollow sleeve of the barrier arm 4 onto the fixed bracket 15.

Also, the elongate pole member or mast 3 is hollow for sliding engagement with a shaft (not shown) of the actuator/motor (not shown). As above, a locking pin clip is utilised to removably retain the elongate pole member 3 onto the actuator/motor shaft (not shown) and provide the drive mechanism (not shown) for axial rotation of the mast 3.

As shown, the second paddle member is a 'GO' sign 16 that is mounted to the elongate pole member 3.

The barrier arm 4 is manufactured out of lightweight aluminium material, such that the weight of the arm is minimised.

The road ending of the barrier arm 4 extends out into the roadway when the paddle or sign is out and comprises usual markings along the shaft and standard indicia such as a 'STOP' sign 17 at the shaft distal end (best seen in left side of Figure 8).

The axial rotation of the elongate pole or mast 3 permits movement of the barrier arm 4 in a horizontal plane. As noted above, the 'GO' and 'STOP signs 16,17 or paddles are separate and mounted 90 degrees out of phase with each other i.e. the face of the first paddle member with indicia 'STOP' 17 is mounted substantially perpendicular or at approximately 90° to the face of the second paddle member with indicia 'GO' 16 such that, when the barrier arm 4 is in a closed or first position kerbside (the arm may be turned to be aligned with the road edge and may not be visible to on-coming traffic), the second paddle member with 'GO' indicia faces the on-coming traffic - see right side of Figure 8 . In a second position (see left side of Figure 8), where the barrier arm 4 is turned out across the road lane which presents the barrier arm 4 with the 'STOP' sign 17 to the driver, the second paddle member with 'GO' sign 16 is

2018205085 10 Jul 2018 turned edge on to the driver and hence is not visible.

EXAMPLE 4

With reference to Figures 10 and 11, a pair of remotely operated barrier arm apparatus 1 is shown in a two-way traffic flow situation which are designed to operate as follows:

There are predominately two positions for the barrier arms 4 i.e. inward GO (left and right side of Figures 10 and 11 respectively) and outwards STOP (right and left side of Figures 10 and 11 respectively).

With reference to Figure 10, each base 5 of the portable barrier arm apparatus 1 is positioned on the pavement kerbside with barrier arm 4 parallel to the road traffic direction in a first position which allows traffic or vehicle (A) on the left lane to pass through the roadway. In this first position, a driver in vehicle (A) will sight the second paddle member or 'GO' sign 16 which is mounted on the elongate pole extension member 3 and hence be aware that they can safely pass through the roadway on the left hand side.

An operator with remote or radio transmitter (not shown) which is in radio communication with the receiver unit (not shown) housed in the base 5 is at a safe point located away from traffic or vehicles (A) and (B).

In order to stop traffic or vehicle (B) on the right side lane of the roadway (Figure 8), the operator presses a single button on the remote or radio transmitter which sends an RF signal to the receiving unit within the base 5 thereby activating the actuator/motor for axial rotation of the elongate pole member

3. This in turn allows 90 degree rotation of the barrier arm 4 such that barrier arm 4 rotates 90 degrees in a horizontal plane and provides a physical barrier to vehicle (B) on to the roadway while exposing the face of the first paddle member or 'STOP' sign 17 at the shaft distal end to the driver (i.e. second position). Simultaneously, the second paddle member or 'GO' sign 16 which is mounted on the elongate pole extension member 3 perpendicular to the first paddle member or 'STOP' sign 17 is rotated out of view of the driver of vehicle (B).

To allow traffic back through the roadway, the order of operation as described above is reversed and the button on the remote pressed again, such that the barrier arm 4 is parallel to the road traffic direction in a first position (right side view of Figure 9).

Aspects of portable barrier apparatus for manual traffic control have been described by way of example only and it should be appreciated that modifications and additions may be made thereto without departing from the scope of the invention as claimed herein.
