[0001] The present invention relates to a device for fitting over at least a portion of
the housing of a fuel delivery nozzle.
Background of invention
[0002] Devices for displaying information on a fuel delivery nozzle, for example a petrol
pump nozzle, are known. Such devices are often subjected to rough treatment in use,
for example being dropped or run over by the wheels of automotive vehicles, and it
is relatively common for such devices to be damaged or dislodged in use.
[0003] The environment in which such devices are used also commonly leads to the devices
coming into contact with volatile and potentially damaging chemicals. The display
window common to such devices, through which information is displayed to an operator,
is therefore commonly subject to degradation or breakage, requiring replacement of
the display window when the device is in service, while allowing the display window
to remain attached in use. There is also a need for the display window to be removable
so that the information displayed on the device can be updated in use.
[0004] Furthermore, such devices are often assembled and attached to the fuel delivery nozzle
by persons who lack mechanical assembly skills, therefore there is a risk of incorrect
assembly when such persons assemble the display device to the fuel delivery nozzle.
Such incorrect assembly can often lead to parts falling off in use and being damaged
or lost.
[0005] Finally, at least two types of fuel delivery nozzle exist, 'standard' and 'vapour
recovery', these having differing physical dimensions and shape. Known types of display
devices for attaching to a fuel delivery nozzle use different attachment methods and/or
components for attaching to different types of fuel delivery nozzles. Problems exist
with the known display devices whereby incorrect components for attachment may be
used which leads to insecure fitment, loss and/or breakage of the display device.
Additionally, the correct components for fixing the display device to the fuel delivery
nozzle may not be immediately available, thereby causing undue inconvenience to the
user of the display device.
[0006] The invention is set out in the claims.
[0007] An improved display device with a more intuitive method of assembly is thus provided,
in terms of both how the individual parts making up the display device are assembled
to each other, and how the complete display device is assembled to the fuel delivery
nozzle. An improved display device is further provided, requiring less assembly by
users in the field, and less disassembly and subsequent re-assembly in the field.
An improved display device which is suitable for fixing to both types ('standard'
and 'vapour recovery') of fuel delivery nozzle is thus provided.

Detailed description
[0009] As shown in Fig. 1, in an embodiment, the present invention incorporates a body (10),
also referred to herein as a hood. As shown in Fig. 2, the hood (10) is constructed
with an internal lattice structure (18) which is both relatively strong and lightweight,
and defines a display surface (40). The display surface (40) can accommodate information
for display, which may be carried on a card or other suitable media, and which is
viewable through a transparent lid or cover (20). The lid (20) is hingeably attached
to the hood (10) by a hinge (50). The hinge (50) is arranged so that the lid (20)
can be detached from the hood (10) if necessary, this being necessary, for example,
if the lid (20) has become degraded or damaged. A splashguard (80) is optionally fitted
to the hood (10).
[0010] As shown in Figs. 1 and 2, the reverse side of the hood (10) from that having the
display surface (40) is shaped so as to be compatible with the shape of common types
of fuel delivery nozzle (90), including particularly those commonly known as 'standard'
and 'vapour recovery' types, both of which include a pipe (95) projecting from a housing
or boot (92) moulded or otherwise formed thereon. The pipe (95) diameter and housing
(92) size of the 'vapour recovery' type of fuel delivery device is relatively larger
than the corresponding diameter of the 'standard' or 'slimline' type of fuel delivery
device nozzle (90). The front of the fuel delivery nozzle (90) is herein defined as
a point closest to the pipe (95) opening. It will be appreciated that a substantial
match between the shape of the hood (10) and the shape of the fuel delivery nozzle
housing (92) is all that is required for effective attachment of the hood (10) to
the fuel delivery nozzle housing (92), an exact match being unnecessary. As shown
in Fig. 5, the hood (10) is secured to the fuel delivery nozzle (90) by securing means
or element (30), in this embodiment, a generally U-shaped, rigid clip (30).
[0011] Referring to Fig. 3, the hood (10) includes an upper surface, also referred to as
a display surface (40), which is generally oval in shape and downwardly gently curved
when viewed from the side. A skirt (60) descends from the upper surface (40) defining
parallel sidewalls (15) and curved front and rear end walls (16, 17). As shown in
Fig. 6, the inner face of each sidewall (15) incorporates one of a pair of parallel
passageways or channels (35) in which the distal ends (32) of the clip (30) slideably
locate. The channels (35) in the hood (10) are parallel to each other and oblique
relative to the general direction of the upper surface (40) of the hood (10), and
thereby the length of the channels able to be accommodated in the hood is increased
relative to that which would be achieveable if the channels (35) were aligned in a
normal direction to the general direction of the upper surface (40). Thereby the range
of adjustment of the clip (30) is extended such that it is suitable for encompassing
attachment of both 'standard' and 'vapour recovery' types of fuel delivery nozzle
to the hood (10). The clip (30) includes a central portion (31) for engaging against
the nozzle housing (92) and end arms (33) each receivable in the channel. The angle
of the channels (35) also causes the clip (30) to be located at an angle such that
the central portion (31) of the 'U' section of the clip (30) is located around a forward
portion of the fuel delivery nozzle housing (92). The point where the clip (30) is
secured or attaches to the hood (10) is located substantially centrally between the
front (16) and rear (17) end walls of the hood (10). Thereby, the security of attachment
of the hood (10) to the fuel delivery nozzle (90) is increased. The clip (30) incorporates
screw receiving holes (73) at each distal end (32). The hood (10) incorporates corresponding
screw locating holes (71) through which screws (72) can be inserted. The shafts of
said screws (72) engage in screw receiving holes (73) of the clip (30) in order to
retain the clip (30) in position in the hood (10).
[0012] Turning to the hinge arrangement, as shown in Figs. 3 and 4, the lid (20) is hinged
to the hood (10) by a hinge (50). The hinge (50) allows the lid (20) to be opened
sufficiently far that access to the screws (72) can be gained without the necessity
to detach the lid (20) from the body (10). In particular, as shown in Figs. 7 and
7a, the lid (20) includes opposing claws (22) which define a concentric cylindrical
space therebetween, and are slideably received around corresponding cylindrical stubs
(12) of the body (10), to a position where they are retained by a detent from which
they can be forced to remove the lid. In the detent position the claws (22) are rotatable
around the stubs (12) providing the hinging action. The lid (20) incorporates a clip
(25) on its end opposite to the hinge (50), the clip (25) being receivable into a
locating hole (19) on the body (10) and suitable for retaining the lid (20) in the
closed position when the display device is in use.
[0013] The splashguard (80) optionally locates in the hood (10) and is retained in position
between the fuel delivery nozzle (90) and the hood (10).
[0014] The hood (10) optionally comprises an overhanging lip (60) aligned with the position
where multiple parts of a mould come together. This reduces the prominence of the
appearance of 'flashing' which is a problematic feature of injection moulding.
[0015] In operation, the hood (10) is positioned to at least partially cover the fuel delivery
nozzle (90) and is attached thereto by means of the clip (30) which is slideably located
in the angled channel (35) incorporated in the hood (10). The 'U' portion of the clip
(30) locates around the fuel delivery nozzle (90) and the ends of the 'U' shaped clip
(30) are attached to the hood (10) by screws (72) inserted through the top of the
hood (10) until the hood (10) is firmly fastened and can accommodate both 'standard'
and 'vapour recovery' types of fuel delivery nozzle (90). The general direction of
the display surface (40) is ideally close to the general direction of the pipe (95)
of the fuel delivery nozzle (90) so that the height or thickness of the body (10)
is minimised. The obliqueness of the channel (35) in which the clip (30) is slideable,
relative to the pipe of the fuel delivery nozzle, allows the range of adjustment of
the clip (30) to be greater than if a clip adjustable in a substantially normal direction
to the pipe of the fuel delivery nozzle was employed. The increase in adjustment range
is achieved without necessitating an increase in the thickness of the body (10) relative
to the display surface (40) area. The thickness or height of the body (10) is thereby
able to be minimised while still allowing a relatively wide range of adjustment of
the clip (30).
[0016] This advantageously avoids problems with the incorrect type of clip (30) being ordered,
reduces problems of leftover stock, and thereby reduces waste and stock storage costs,
reduces the number of parts to be manufactured and associated tooling costs, reduces
problems with incorrect assembly due to the wrong clip being used by an operator,
and reduces associated problems of insecure attachment leading to display devices
becoming detached from the fuel delivery nozzle (90) and possibly then becoming damaged.
[0017] In operation, the lid (20) is removably hinged to the body (10) and arranged to hold
in place an information card upon which is placed information. The information on
the information card is viewable through the lid (20) which is transparent. The lid
(20) can be supplied pre-assembled to the body (10). The hinged arrangement of the
lid (20) to the body (10) allows the lid (20) to be hinged open so as to gain access
to both the information card and to the screws (72) which secure the clip (30) to
the body (10), without the need to separate the lid (20) from the body (10). The possibility
of incorrect user assembly of lid (20) to body (10) is thereby obviated, which advantageously
reduces the risk of detachment of lid (20) in use, and subsequent loss or damage.
The lid (20) is removable by the use of force greater than that normally encountered
when merely hinging the lid (20) open. The facility to replace damaged or degraded
lids in service easily and efficiently is therefore provided, with reduced risk of
losing the lid by inadvertent detachment.
[0018] It will be appreciated that further variations on the described embodiments are possible.
For example, the clip can incorporate barbs on its ends which locate in receiving
indentations in the body, rather than being secured by screws. Alternatively, the
clip could be a flexible securing means such as a tie wrap. The clip may secure to
itself in order to provide securing tension, or may be secured to the body in order
to provide securing tension. The channels in the body can be open sided channels or
closed sided channels or passageways. The channels or passageways can be closed at
the display surface end (for example if the clip is secured by barbs) or can be open
at the display surface end (for example if the clip is secured by screws secured into
the ends of the clip). The channel may be perpendicular rather than oblique if the
height of the hood permits. The display surface may be an upper surface that is user
viewable, opposed to a nozzle engagement surface.
[0019] Suitable materials for construction of the hood (10) are plastic, rubber or similar
materials. The lid (20) is constructed from a transparent plastic, nylon, or similar
material. The hood (10) and lid (20) can be formed by a process of injection moulding
or other suitable process for forming such materials. The clip (30) is constructed
from a suitable rigid material such as plastic or metal, which may be injection moulded
or formed by a bending process, or by die casting, or by other suitable processes.
The splashguard (80) can be constructed from a compliant rubber material, or other
similar material, by a process of injection moulding or other similar process.
