Description
An outdoor parasol heater
Field of the Invention
to a combined outdoor parasol heater and foot heating
arrangement. In a preferred embodiment the invention
relates to a parasol heater and foot heater arrangement
which are fuelled from the same gas supply.
Background to the Invention
Parasol heaters are well known in the art and are used for
outdoor heating. They utilise a gas fuel supply which is
provided in an housing in a lower portion of the heater. A
pole extends upwardly from the lower portion to a burner
arrangement which is above head height. A parasol dish is
provided above the burner arrangement and is adapted to
deflect heat downwardly about the pole, thereby providing
for a heating or warming of persons around the heater. One
example of such a parasol heater is described in EP 0 976
979, of the present inventor, which describes a parasol
heater which provides the parasol in multiple sections so
as to enable an efficient packing of same.
The traditional parasol heaters were only provided with a
heater in an upper region thereof. The present inventor has
modified such simple arrangements to incorporate other
features such as tables, a light and also a table barbecue.
Such arrangements are described in GB 0125122 and IE
S2000/0879. These adaptations are advantageous in that
additional benefits are provided to the user. Not only can
he extend the sitting out period in the outdoor environment
by utilisation of the parasol heater but he can also
provide lighting in the event that the user wishes to sit
out in the evening or night time. Furthermore, the
provision of a table barbecue enables the user(s) to sit
around the parasol heater, taking advantage of the heat and
light provided, and cook or prepare his food. This
combination of features has prompted the user to extend
further the time period in which they wish to sit out.
A problem in providing such additional structures to the
user and enabling the user to sit around the parasol heater
is that the heat from the parasol heater cannot always make
its way to regions about the lower portions of the parasol
heater. Thus, the users’ lower trunk portions and legs can
be occluded from the heat and may become susceptible to
cold. This is a problem also in situations not involving
the additional parasol “furniture” described above, but
where the users are not standing or sitting in an erect
position but rather lounging or lying about. As the
distance from the user to the warmth of the parasol heater
is now increased, the heat provided by the parasol has
dissipated greatly before it reaches the users.
There is therefore a need to provide a heating arrangement
for heating regions immediately above the ground level so
as to provide for a warming of the lower portions (feet,
legs etc.) of users. The easiest, and most common, way to
do this is to provide a fire, for example in the form of a
campfire or braziers about which people can sit. As the
parasol heater utilises a bottled gas supply it is
important to keep it away from such direct heat for fear of
combustion of the gas. Such arrangements thereby require
the users to provide the parasol heater away from the
campfire or braiier. For example the users may sit around
the campfire, thereby warming their lower portions and
provide one or more parasol heaters in an outer
circumferential arrangement about the fire to provide
warmth for their backs and upper portions. This is
|E02(l795
disadvantageous in that it requires a plurality of burners
and, as the persons are only utilising a small portion of
the warmth provided by the burner, is inefficient. It also
suffers in that people tend less to sit around the parasol
heater.
One way to overcome this is to provide for the people to
sit around the parasol heater and provide a plurality of
braziers in an outer circumference about the people.
Although this is more cost effective, as braziers are
cheaper than parasol heaters, there is the problem that
dual supplies of heat are required. Furthermore, the user
of traditional fuels such as campfires and braziers require
a preparation and subsequent cleaning which many find
tedious.
There is therefore a need to provide a parasol heater that
is adapted to provide warmth not only to upper portions of
a user, but also to lower portions.
Object of the Invention
It is an object of the present invention to provide a
parasol heater that provides a heat supply in upper and
lower portions thereof.
Summary of the Invention
Accordingly the present invention provides a parasol heater
having a housing portion adapted to house a bottle of gas,
a pole extending upwardly from the housing portion and
adapted to support a gas burner arrangement, the burner
arrangement being provided below a parasol adapted to
deflect heat generated by the burner downwardly about the
pole and wherein the parasol heater includes a second gas
ED20793

burner arrangement, the second burner arrangement provided
below the housing portion and adapted to provide for a
heating of the environment about the housing portion.
The second burner arrangement is desirably adapted to
provide for a heating of the environment circumferentially
about the housing portion.
The second burner arrangement is desirably provided in a
burner housing, the burner housing having a lower portion
and an upper portion, a series of fingers extending
upwardly from the lower portion to the upper portion,
thereby defining a plurality of apertures from which heat
generated by the gas burner can escape.
The perimeter defined by the lower portion is desirably
greater than that defined by the upper portion such that
the fingers extend upwardly and inwardly from the lower
portion to the upper portion. By providing the lower
portion of greater perimeter area than that of the upper
portion the burning housing provides stability to the
parasol heater mounted above.
The burner arrangement is desirably provided in a mid
portion of the burner housing, directly below the housing
portion for the bottle of gas.
The upper portion is desirably provided with insulation
means adapted to insulate the lower portion of the housing
portion from heat generated by the burner arrangement. The
insulation ensures that a bottle of gas contained within
the housing is not heated by the burner arrangement
provided below.
|EU20793
The insulating means desirably includes a plurality of
individual insulating layers. In a preferred embodiment,
the layers are selectable from one or more of the following
types of insulation:
an air gap,
an insulating membrane,
a layer of steel or similar metallic structure, and/or
a reflective layer.
The use of a reflective layer directly above the burner
arrangement serves to reflect heat downwardly from the
upper portion of the burner housing. The provision of one
or more layers of steel or similar metallic material in
combination with one or more layers of insulating membranes
provides a sandwich structure which provides additional
heat insulation in the upper portion.
In a first embodiment a plurality of layers are provided in
a sequence of a first reflective layer having a first steel
layer provided thereon, the first steel layer having an
insulating membrane provided thereon, the insulating
membrane separating the first steel layer from a second
steel layer, the second steel layer being separated from a
support platform by an air gap.
The thickness of the reflective layer is typically greater
than about 0.8 mm, the first and second steel layers having
a thickness of about 3 mm each, the air gap having a height
of about 20 mm and the insulating membrane being about 15mm
in thickness.
The burner arrangement desirably provides at least about
l.5KW of heat energy. The burner arrangement may include a
catalytic converter.
|EU20795
In a first embodiment the burner arrangement is provided
with a control knob on an outside surface of the burner
housing. In an alternative embodiment the control knob may
be provided elsewhere on the parasol heater, such as for
example adjacent to the control knobs for the parasol
burner arrangement.
These and other features of the present invention will be
better understood with reference to the following drawings.

Detailed Description of the Drawings
The present invention will now be described with reference
to Figures 1 to 5 of the accompanying drawings.
As shown in Figure 1, the present invention provides a
parasol heater 100 having a housing portion 105 adapted to
house a bottle of gas. A pole 110 extends upwardly from the
housing portion 105 and is adapted to support a gas burner
arrangement 115. The burner arrangement 115 is provided
below a parasol dish 120 which is adapted to deflect heat
generated by the burner downwardly about the pole. In the
|EU20793
embodiment of Figure l the parasol dish is formed in
multiple sections 120a, l20b but it will be appreciated
that the dish 120 may be formed in one or more pieces or
sections depending on the preference or intended use. The
embodiment of Figure 1 also includes a lighting arrangement
125 provided between the burner arrangement ll5 and the
pole llO, but again it will be understood that the present
invention is not intended to be limited to parasol heaters
with or without lights, as they can be included or omitted
depending on the application of the invention.
As is seen in Figure l, the present invention provides for
a second burner arrangement to be incorporated with the
parasol heater. In the embodiment illustrated in Figure l
the burner arrangement is provided in a burner housing 130,
the burner housing being below the housing portion 105 for
the bottle of gas. By providing a burner arrangement below
the housing lO5, the parasol heater of the present
invention provides for a heating of the environment about
the housing portion lO5.
The burner housing is provided with a lower portion l35 and
an upper portion 140. The upper and lower portions are
separated by a series of fingers l45 extending upwardly
from the lower portion 135 to the upper portion 140,
thereby defining a plurality of apertures 150 from which
heat generated by the gas burner can escape.
The plurality of apertures 150 about the burner housing 130
provide for an escape of heat, as generated by the burner
within the housing, out in a radial or circumferential
pattern about the housing portion.
In the preferred embodiment shown in the accompanying
figures, the perimeter defined by the lower portion is
lEn2n793
greater than that defined by the upper portion. As such,
the fingers 145 extend upwardly and inwardly from the lower
portion to the upper portion. By providing the lower
portion of greater perimeter area than that of the upper
portion, the burning housing provides stability to the
parasol heater mounted above. It also provides for a
dissipation of the heat generated by the burner within the
burner housing away from the housing 105 for the gas supply
bottle.
As shown in Figure 2, which shows a portion of the parasol
heater of Figure 1 with the housing 105 removed, a gas fuel
supply bottle 200 is provided with a fuel line 205 which
branches into at least two individual supply lines 210,
215. A first supply line 210 extends upwardly so as to
provide fuel for the burner arrangement 115, whereas a
second fuel line 215 passes downwardly to provide fuel for
the burner provided in the burner housing 130. The fuel
lines are typically provided in a conventional flexible
rubber material and in the case of the second fuel line 215
is connectable to fixed supply conduit 220 which is
connectable to the burner arrangement within the burner
housing 130.
Although shown as only one fuel line passing upwardly, it
will be appreciated that if a number of other appliances,
such as the lighting arrangement 125, are provided that
this fuel line 210 may be branched further so as to provide
for fuelling each of these separately. In this manner the
present invention provides for the fuelling of two or more
individual components of the parasol heater using the same
gas supply bottle 200.
As shown in Figures 3 and 4, a burner arrangement 400 is
desirably provided in a mid portion of the burner housing
IEU20793
, directly below the housing portion for the bottle of
gas. This is desirably effected by providing a support
bracket 420 in a mid portion of the housing 130, the
bracket adapted to support the burner 400. In the
embodiment of Figure 4, three cross members 425 are
arranged within an inner portion of the burner housing 135.
The cross members are arranged equidistant apart about the
circumference of the burner housing 135 and extend from the
side walls, as defined by the fingers 145, into the support
bracket 420. Not only do the cross members 425 provide
support for the bracket 420, they are also advantageous in
that the provide structural support for the housing 135.
The fuel supply conduit 220 extends through an upper
surface 300 provided in an upper region 140 of the housing
to a control manifold 430 mounted to an inner portion of
the housing opposite to a control knob 310 provided on a
corresponding outer surface of the housing. Movement of the
control knob 310 effects a control on the volume of gas
that can pass from the supply conduit 220 to a direct feed
supply 405 for the burner 400. Additional electrical
connections 410 which provide for an ignition of the burner
400 also extend from the control manifold 430. The burner
is typically of a conventional type and is desirably
adapted to provide at least about l.5KW of heat energy. The
burner arrangement may include a catalytic converter, which
is not shown in these figures.
In this preferred embodiment the control knob is provided
on an outside surface of the burner housing. In an
alternative embodiment, which is not shown, the control
knob may be provided elsewhere on the parasol heater, such
as for example adjacent to control knobs 155 for the
parasol burner and lighting arrangements (see Figure 1).
|ED2fl7As shown in Figures 3 and 5, the upper portion 140 is
desirably provided with insulation means 320 adapted to
insulate the lower portion of the housing portion (i.e.
where the gas bottle will sit) from heat generated by the
burner arrangement. The insulation ensures that a bottle of
gas contained within the housing is not heated by the
burner arrangement provided below.
The insulating means desirably includes a plurality of
individual insulating layers. In a preferred embodiment,
shown in the section of Figure 5, the layers are selectable
from one or more of the following types of insulation:
an air gap 505
an insulating membrane 510
a layer of steel or similar metallic structure 515,
and
a reflective layer 520.
The use of a reflective layer 520 directly above the burner
arrangement serves to reflect heat downwardly from the
upper portion 140 of the burner housing. The provision of
one or more layers of steel or similar metallic material in
combination with one or more layers of insulating membranes
provides a sandwich structure which provides additional
heat insulation in the upper portion.
In the embodiment shown in Figure 5, a plurality of layers
are provided in a sequence of a first reflective layer 520
having a first steel layer 515 provided thereon. The first
steel layer is provided with an insulating membrane 510
thereon, the insulating membrane separating the first steel
layer 515a from a second steel layer 515b. Above the second
steel layer 515b, an air gap 505 is provided, the air gap
separating the second steel layer 515b from a support
|E02fl7platform 525. The support platform 525 provides a support
for the bottle or cannister of gas when placed within the
housing 135.
The thickness of the reflective layer is typically greater
than about 0.8 mm, the first and second steel layers having
a thickness of about 3 mm each, the air gap having a height
of about 20 mm and the insulating membrane being about 15mm
in thickness.
It will be appreciated that the insulating means herein
described is exemplary of the type of insulating means that
may be utilised so as to prevent a transfer of heat, as
generated by the burner 400, to the bottle of gas provided
in the housing 135. Any other alternative insulating may
use all or none of the types of layers provided herein to
ensure that the heat is not transferred upwardly.
Similarly it will be appreciated that the configuration of
the finger/aperture arrangement described is not intended
to limit the present invention to such an arrangement, as
it will be understood that a number of different
configurations could be used to ensure an adequate transfer
of heat from the gas burner within the burner housing to
the environment about the lower portion of the parasol
heater.
It will be further understood that the gas burner heater
provided in the base portion can be operated separably from
that of the parasol burner or other fittings to the parasol
heater. Such independent operation is advantageous in that
it provides for individual selection of the type and volume
of heat that is required for a specific user.
|EU207
The present invention provides a parasol heater with
separate individual burner arrangements provided in both
upper and lower portions of the parasol heater. Although it
has been described with reference to specific combinations
of integers it will be appreciated that the present
invention is not intended to be limited to any one set of
combinations and individual integers can be included or
omitted depending on the specific requirements of the
heater.
The words “comprises/comprising” and the words
“having/including” when used herein with reference to the
present invention are used to specify the presence of
stated features, integers, steps or components but does not
preclude the presence or addition of one or more other
