[0001] The present invention relates to a guide device, and to a car park that includes
a plurality of guide devices. In particular, but not exclusively, the invention relates
to a guide device for delimiting the boundaries of parking spaces in which vehicles
may be parked, defining the layout of the car park, and helping drivers to guide their
vehicles into and out of parking spaces.
[0002] In public and private car parks, the dimensions of designated parking spaces are
calculated such that each parking space is wide enough for the parking of a "standard"
vehicle, and allows adequate space between adjacent parked vehicles for the occupants
to get out of and into the vehicles with an assumption of relative ease. The width
is calculated on the assumption that all drivers park their vehicles nearly centrally
within the designated parking spaces.
[0003] Conventional markings on the ground of parking spaces are generally not visible during
a parking manoeuvre and as a result, most drivers will seek to park at around the
midpoint between two adjacent vehicles. It is well known that not all drivers park
neatly, and any inaccuracies in the position of a row of parked vehicles can be perpetuated
and maintained as vehicles join or depart from the row of parked vehicles concerned.
For example, once a driver has located a vacant parking space in a car park, he is
often faced with the situation that the vehicles in the two adjacent parking spaces
have not parked straight and/or in the centre of their respective spaces, thereby
reducing the amount of space available to the driver on parking. A number of problems
arise, the most obvious being that there will be insufficient room for the occupants
to get out of the vehicle. Due to poor parking or mere carelessness, vehicles are
often damaged when the doors of adjacent vehicles are opened, or by manoeuvring shopping
trolleys or prams between the parked vehicles. Vehicles can also be damaged along
their flanks by collision while another vehicle exits or enters a parking space. Poor
parking also results in a loss of parking capacity if the gap between two adjacent
vehicles is too narrow for safe and convenient use.
[0004] The inventor's earlier International patent application No. PCT/GB99/02148 discloses
a guide device for helping drivers to manoeuvre their cars into parking spaces by
employing a barrier device that is within the driver's view. The barrier device is
positioned along the flanks of the parking spaces, occupying the space between parked
vehicles, thereby preventing shopping trolleys, prams and similar hazards from parking
between parked vehicles. By denying easy access to the rear of the parking spaces,
drivers are obliged to manoeuvre their vehicles forward into the parking space, leaving
their rear luggage compartment adjacent to the aisle, rather than reversing into the
parking space, which is more time consuming and hazard prone. The structure and materials
of the barrier device are such that the device will not injure the surface of the
car in the event of contact or impact.
[0005] However, this guide device has a number of limitations.
[0006] The guide device is relatively long, extending along the flank of the vehicle and
causing interference with the opening doors. Although the horizontal arm of the device
will deflect upon the opening of a vehicle's doors, some drivers anticipate physical
inconvenience from the device's presence between parked vehicles, for example interference
with the opening doors of any wider than average vehicle, or interference with the
opening of vehicle doors in use by a less than physically able driver or passenger.
[0007] Herringbone car parks use one way aisles in either direction on either side of chevronned
parking spaces set at an angle to the aisles. A common problem encountered in car
parks of herringbone configuration arises when drivers drive through a vacant bay
in front oftheir parking space to emerge in the next aisle going the wrong way. Another
problem arises when drivers position their vehicle by reference to the adjacent vehicle,
failing to take account of the offset, which is created by the fact that the parking
spaces are at an angle to the aisle. Vehicles are therefore often parked with their
rear extremity in the aisle, thereby causing an obstruction in the aisle. The guide
device disclosed does not demarcate the end boundary of the parking space or prevent
drivers driving through a vacant bay in front to emerge in the next aisle.
[0008] The guide device is also fixed into position by cramp bolt, adhesive or grouting
and is therefore only suitable for use on hard, solid car park surfaces, such as concrete
or tarmacadam. In particular, it is not suitable for use on grass or aggregate.
[0009] Grass or aggregate parking areas are commonly used for overflow or similar light
duty purposes. Grass, aggregate and similar surfaces can be constructed with an engineered
sub-base sufficient to allow their use in low turnover parking situations, such as
daily employee or commuter parking. Grass parking can be virtually maintenance free,
but its present limitation is in providing physical organisation and visual structure
to the surface of the parking area. White painted lines or similar delineations frequently
have to be re-made and are therefore inappropriate.
[0010] Where there are no ground markings, vehicles are often directed nose to tail along
roads and access lanes, and then supervised by stewards into self generating rows
and aisles of parked vehicles. Drivers tend to park further apart than in designated
car parks thereby creating a reduced parking density. Upon exit, drivers return to
their vehicles in no particular order, and then commence moving out of the car park
"ad hoc". Most drivers take the nearest competitive shortcut to the exit, which results
in congestion.
[0011] The aim of the present invention is to provide a guide device and car park that includes
a plurality of the guide devices that mitigate at least some of the above-mentioned
problems.
[0012] According to the present invention, there is provided a guide device for helping
drivers to guide their vehicles into parking spaces, said guide device including a
support member that is constructed and arranged to stand on the ground, at least one
arm that is supported by the support member and in use extends substantially horizontally
from the support member, and a ground anchor having a lower part for anchoring in
the ground and an upper part to which the support member may be attached.
[0013] The present invention encourages and helps drivers to park their vehicles in parking
spaces more accurately, so that they are parked near the centre and nearly straight
within the parking space. The guide device is positioned above the ground, within
the driver's line of sight, thereby providing visual and physical guidance to drivers
engaged in manoeuvring into or out of a parking space.
[0014] Advantageously, the support member includes a ground-contacting portion that is deformable
to accommodate movements of the ground.
[0015] Advantageously, the support member includes a resilient plastics moulding.
[0016] Preferably, the support member includes ground engaging elements for preventing rotation
of the support member relative to the ground.
[0017] Advantageously, the ground engaging elements comprise spikes on a lower surface of
the support member.
[0018] Advantageously, the ground anchor includes a spike that is suitable for being driven
into the ground.
[0019] Preferably, the guide device includes means for attaching and locking the ground
anchor to the support member to prevent rotation relative thereto.
[0020] Advantageously, the guide device includes a plurality of arms that are supported
by the support member, said plurality of arms including a first arm for demarking
a side boundary of a parking space and a second arm for demarking an end boundary
of a parking space.
[0021] The present invention further provides a guide device for helping drivers to guide
their vehicles into parking spaces, said guide device including a support member that
is constructed and arranged to stand on the ground, and a plurality of arms that are
supported by the support member, said plurality of arms including a first arm for
demarking a side boundary of a parking space and a second arm for demarking an end
boundary of a parking space.
[0022] The guide device helps drivers to park their vehicles accurately within a parking
space. The first arm demarking the side of the parking space helps drivers to position
their vehicles straight within the parking space. The second arm demarking the end
of the parking space is directly in front of the driver and provides a visible designation
to the end of the parking space so that vehicles are parked further forward in the
parking spaces, thereby preventing the rear extremity of the vehicle from obstructing
the aisle. The second arm also prevents drivers from driving though a vacant bay in
front of their parking space.
[0023] Preferably, the first and second arms are constructed and arranged to be substantially
horizontal in use.
[0024] Preferably, the first and second arms are substantially perpendicular to each other.
[0025] Preferably, the first arm is substantially longer than the second arm.
[0026] Advantageously, the first arm has a length in the range 100-300cm, preferably approximately
150cm, and the second arm has a length in the range 100-150cm, preferably approximately
80cm.
[0027] Preferably, the support member is constructed and arranged to be substantially vertical
in use.
[0028] Preferably, the or each arm is made of a plastics material.
[0029] Advantageously, the or each arm is made of polyethylene.
[0030] The present invention further provides a car park having a plurality of guide devices
including any of the features described in the preceding statements of invention,
said guide devices being arranged to define the layout of the car park and demark
the boundaries of parking spaces within which vehicles may be parked.
[0031] The car park may have a grassed surface or any other suitable surface, for example
aggregate or tarmac.
[0032] Advantageously, the car park includes a plurality of vehicle access lanes, said parking
spaces being set at an acute angle to the access lanes.
[0033] Advantageously, the car park has a herringbone layout.
[0034] An embodiment of the invention will be described, by way of example, with reference
to the accompanying diagrams, in which:
Figure 1 is a plan view of a car park, illustrating the positions of the guide devices;
Figure 2 is a top view of the guide device;
Figure 3 is a side view of the guide device;
Figure 4 is a end view of the guide device;
Figure 5 is a side view of a mounting peg and bolt;
Figure 6 is a partially sectional side view of a mounting pin and bolt;
Figure 7 is a cross-sectional view of the mounting pin, and
Figure 8 is a side section, showing the mounting pin in use.
[0035] Figure 1 shows the use of the guide device 2 to delimit the width of each parking
space 4 in a "chevron" or "herringbone" parking layout. The guide device is fixed
to the ground towards the end of the parking space 4.
[0036] The guide device is shown in figures 2, 3 and 4, and consists essentially of two
horizontal arms 6,8, which are arranged at 90° to each other and attached to a perpendicular
support 10. The device is then mounted on a mounting peg 12 that is driven into the
ground, and is secured to the peg by means of a bolt 14.
[0037] The device 2 is preferably made of a low friction, high density plastic, for example
polyethylene.
[0038] The arms 6,8 are of different lengths, approximately 150cm and 90cm respectively,
and are positioned at a height of approximately 80cm above the ground.
[0039] The support 10 includes a bolt hole 16, approximately 40cm from the end of the support
for securing the device in position by means of a bolt 14 to the mounting peg 12.
The mounting peg extends downwards through a hole in the base of the support and is
positioned off-centre relative to the support, thereby discouraging rotation of the
device. For mounting the device on unstable surfaces, such as grass or aggregate,
the support 10 includes downwardly projecting teeth 18 on the base of the support
and a flexible collar 20. The downwardly projecting teeth 18 help prevent rotation
of the device once it has been secured in position. Once the device has been secured
in position, the flexible collar 20 maintains the downward pressure of the device
on the ground, whilst allowing for ground movement, for example seasonal heave due
to a varying amount of surface moisture in clay or similar soils.
[0040] The mounting peg 12, shown in figure 5, is cruciform in section. It is approximately
90cm in length and made of galvanised steel. A nut 21 is welded in the top end of
the mounting peg. There are also castellations (not shown) on the top of the mounting
peg. The bolt 14 is a tamper proof bolt. A steel washer 22 and a plastic washer 24
are used when attaching the support member securely to the mounting peg.
[0041] Operation of the guide device will now be described in relation to use on a grass
or aggregate surface.
[0042] Once the position of the guide device at the end of the parking space has been determined,
the mounting peg 12 is inserted approximately 50cm into the ground. The support member
10 of the guide device is then placed over the projecting part of the mounting peg
12. The guide device is then bolted to the mounting peg 12. The guide device is positioned
so that the longer arm 6 is directed along the side and the shorter arm 8 along the
end boundary of I the parking space. Before the bolt 14 is tightened, the guide device
can be rotated on the mounting peg 12 until correctly aligned with adjacent guide
devices and the intended car park geometry. When correctly aligned the bolt 14 can
be tightened compressing its fabric between the castellations on the top of the peg
and the plastic washer 24 above, thereby preventing further rotation. Rotation of
the device is also prevented by means of the downwardly projecting teeth 18 on the
base of the device, which engage with the surface of the ground.
[0043] When the support member is fixed to the mounting peg with the bolt 14, the flexible
collar is compressed against the ground and will maintain downward pressure on the
ground surface, and make good any loss of soil volume following installation, or seasonal
heave due to varying amounts of surface moisture in the ground.
[0044] The device helps guide drivers and their vehicles into a parking space so that when
parked the vehicle is positioned near to the centre of the designated bay.
[0045] The shorter arm 8 is positioned along the end boundary of the parking space and prevents
drivers from driving through the parking space into a vacant parking space in front.
When the parking layout has a herringbone configuration, this prevents the driver
from emerging in the next aisle going the wrong way and thereby disrupting traffic
flow. The shorter arm 8 also provides a visible designation of the position of the
end of the parking space, further helping the driver to position the car correctly
within the parking space.
[0046] The position of the guide device also prevents damage to the flanks of the vehicles
by preventing the manoeuvring of shopping trolleys and prams between parked vehicles.
[0047] Due to the increased accuracy of parking by drivers into and out of parking spaces,
the width of the access lanes to the parking spaces could be reduced. This will increase
the potential capacity of a parking area.
[0048] The use of the guide device on grass, aggregate or similar surfaces enables the greater
potential for use of these areas as more efficient parking areas. Grass and similar
car parks can be cost effectively constructed to durable engineering standards. They
also have the advantage of being permeable to rain water, and therefore do not contribute
to storm water flows in piped drainage and in nearby rivers, or keep rain water from
aquifers or ground water beneath.
[0049] A mounting pin, which can be used as an alternative to the mounting peg to hard surfaces
such as tarmac or concrete, is shown in Figs. 6 to 8. The mounting pin 30 is made
of any suitable material such as stainless steel and is generally cylindrical, having
a length of 460mm and a diameter of 20mm. The lower portion 32 of the pin (e.g. the
bottom 100mm) has a cruciform cross-section, as shown in Fig. 7. At its upper end,
the pin has a collar 34 of a plastics material, for example HDPE, which is engaged
by a washer 36 and a bolt 38 that engages a threaded bore 40 in the upper end of the
peg. The head of the bolt is protected with an armoured ring 42.
[0050] In use, a 20mm diameter hole 44 is drilled into the ground and filled with epoxy
resin, which serves as a fixative and a sealant. The peg is inserted into the hole
to the depth of the cruciform lower section 32 (as shown in Fig. 3), leaving the upper
section 46 standing above ground level. The support member is placed over the peg
and the collar 34 is then placed onto the peg and the bolt 38 and washer 36 are located
in position and fastened down, to compress the collar against the support member.
This locks the support member in position. If necessary, and adhesive pad (not shown)
can be placed underneath the support member, to prevent it turning relative to the
ground.
[0051] Various modifications of the guide device are envisaged, for example the device may
have three or even four orthogonal arms designating the limits of adjacent parking
spaces in different configurations of car park layout.
[0052] When the device is to be used on hard solid surfaces, such as concrete or tarmacadam,
the upper part of the mounting peg can be fixed to the surface of the ground by a
corrosion resistant metal flange, which can then be cramp bolted or otherwise attached
to the surface.
[0053] There is also a potential for providing advertising material on, or attached to the
device.
