DETAILED DESCRIPTION

[0028] One embodiment of the present invention will now be described with reference to FIGS. 1 to 5 of the accompanying drawings.

[0029] As shown in FIG. 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.

[0030] In the embodiment of FIG. 1 the parasol dish is formed in multiple sections 120a, 120b 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 sections can be coupled or engaged with one another in a variety of different ways such as for example overlapping adjacent edge portions of adjacent sections and then securing these overlapping sections using bolts or the like.

[0031] Alternatively an interlocking folding arrangement may be used. These and other way to secure adjacent sections—which are provided to the user in a disassembled state and are then secured together on-site will be apparent to the person skilled in the art.

[0032] As is evident from FIG. 1 the gas burner 115 is provided below the parasol dish 120, the parasol dish being adapted to deflect heat generated by the gas burner downwardly about the pole. Per the present teaching the parasol is adapted to be tilted relative to the top 115A of the gas burner 115. The tilting is achieved by having the parasol dish pivotably connected to the gas burner by a pivot coupling which is adapted to allow the parasol dish to move in an arc over a side edge of the gas burner. This arc is also an arc relative to a longitudinal axis 125 of the pole 110.

[0033] The heater 100 further comprises a tilting actuator 130, in the form herein exemplified as a handle, coupled to the dish and extending over the gas burner 115.

[0034] The parasol dish 120 is further rotatably connected to the pole by a rotatable coupling 140 which is adapted to allow the parasol dish to rotate about the longitudinal axis 125 of the pole.

[0035] In use actuation of the rotatable coupling and movement of the tilting actuator effects a corresponding movement of the parasol dish through the pivot coupling and about the longitudinal axis to allow for targeted reflection of heat from the gas burner.

[0036] As shown in FIG. 1 but also in the detail of FIG. 2, the parasol dish is preferably coupled to the gas burner such that the gas burner and parasol dish rotate together on actuation of the rotatable coupling. In this way the parasol is configured to tile relative to the burner but rotate in unison with the burner.

[0037] FIG. 2 shows a burner housing 200, the burner housing comprising each of the gas burner and the parasol dish.

[0038] The rotatable coupling 140 comprises at least one bearing 205, in this embodiment two bearings 205, 210, which are each configured to engage with the burner housing 200 to enable a rotation of the burner housing about the longitudinal axis of the pole. By providing the bearings, the fluidity of motion is improved but also the rotation movement is less prone to degradation over time through use of for example a simple interference fit between two metal parts.

[0039] The rotatable coupling desirably comprises an insert 220, the insert being configured to couple to each of the burner housing 200 and the pole 110, the at least one bearing 205, 210 being provided on the insert.

[0040] The insert 220 is desirably dimensioned to be received within each of the burner housing and the pole, the insert extending between the burner housing and the pole. In this way, and as seen in FIG. 2, each of the burner housing and the pole define a receiver—or socket—within which the insert 220 is located, the insert spanning across between the pole and the burner housing.

[0041] The insert 220 is desirably dimensioned to be at least partially supported by the pole. This support can be provided by a top surface of the pole defining a ledge upon which the insert is seated.

[0042] As is visible in FIG. 2, and again in FIG. 4, where first and second bearings 205, 210 are provided, they are desirably spaced apart from one another on the insert so as to distribute the load of the supported burner housing 200.

[0043] The rotatable coupling is desirably configured to constrain the rotation to less than 360 degrees. This can be achieved, per FIGS. 3A and 3B (FIG. 3B is a section along the line B-B) through use of a stop screw 300 that projects through the burner housing 200 to engage with a detail abutment 310 that is provided on the insert 220. The detail abutment 310 is desirably asymmetric in form and is configured in use to engage with the screw to prevent rotation. The use of a stop screw advantageously allows the user to selectively control whether constrained rotation is actuated or not.

[0044] As shown in FIGS. 4 and 5 (FIG. 5 is a section along the line C-C of FIG. 3B), the rotatable coupling desirably comprises an actuator 400, the actuator being configured to transition between a locked and an unlocked configuration, wherein in the locked configuration the parasol is not rotatable about the longitudinal axis of the pole and in the unlocked configuration the parasol is rotatable about the longitudinal axis of the pole. The locked and unlocked configurations are desirably provided by a clamping action through the use of engaging first and second clamp bodies 410a, 410b against the insert 220. A washer 430 may be provided between an actuator handle 420 and the clamp bodies 410a

[0045] The gas fuel supply is typically a gas bottle supply which is housed within the housing 105.

[0046] The burner arrangement for use in such a parasol heater would be a 13 or 15kW burner which can be run from a bottled gas supply

[0047] The present invention provides a parasol heater with a parasol dish which is rotatable about an axis of the pole on which it is supported. Optionally the dish is also a tiltable parasol dish. 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 features, integers, steps, components or groups thereof. Furthermore the words “upper/lower” and the like are used for ease of explanation only and it is not intended to limit the invention to any one orientation.
