Abstract
A heating device of a portable nature is disclosed. The heating device of a portable nature includes a heating element, a hinged coupled to the heating element, and an arm coupled to the hinge.
Claims28
A heating device of a portable nature comprising:
- a head assembly;
- a hinge coupled to the head assembly;
- and
- an arm coupled to the hinge;
- wherein the head assembly comprises:
- a heating element;
- a reflective shield at least partially surrounding the heating element;
- an external shade at least partially surrounding the reflective shield;
- a chimney extending at least partially through an upper portion of the external shade, the chimney comprising an external vent and a side port;
- and
- an air space between the reflective shield and the external shade, the air space (a) defining a perimeter inlet opening extending around the heating element and (b) communicating with an inside area of the chimney via the side port of the chimney, thereby defining a convective air flow path into the air space via the perimeter inlet opening, through the air space, into the inside area of the chimney via the side port of the chimney, and out of the head assembly via the external vent of the chimney.

A heating device of a portable nature comprising:
- an emitter of electromagnetic energy;
- a reflective shield at least partially surrounding the emitter;
- an external shade at least partially surrounding the reflective shield;
- a chimney comprising a thermally insulating material and extending at least partially through an upper portion of the external shade, the chimney comprising an external vent and a side port;
- and
- an air space between the reflective shield and the external shade, the air (a) defining a perimeter inlet opening extending around the heating element and (b) communicating with an inside area of the chimney via the side port of the chimney, whereby convective air is allowed to flow around the heating device, into the air space via the perimeter inlet opening, through the air space, into the inside area of the chimney via the side port of the chimney, and out through the external vent of the chimney.
3 more elements
A heating device of a portable nature comprising:
- a base;
- a lamp assembly including:
- an emitter of electromagnetic energy aimed towards a target,
- a reflective shield at least partially surrounding the emitter and reflecting at least a portion of the electromagnetic energy towards the target,
- an external shade made from a first thermally insulating material and at least partially surrounding the reflective shield, and
- a chimney thermally insulated relative to the reflective shield and coupled to at least one of the emitter, the reflective shield and the external shade, the chimney comprising an external vent and a side port;
- and
- wherein an air gap between the reflective shield and the external shade (a) defines a perimeter inlet opening extending around the heating element and (b) communicates with an inside area of the chimney through the side port of the chimney, such that convective air is allowed to flow into the air gap via the perimeter inlet opening, through the air gap, into the inside area of the chimney via the side port of the chimney, and out of the head assembly via the external vent of the chimney;
- and
- a support arm mechanically connected to the base and the lamp assembly, wherein the support arm movably supports the lamp assembly.
7 more elements
A heating device of a portable nature comprising:
- a base;
- a lamp assembly comprising:
- a means for generating infrared radiation,
- a means for reflecting infrared radiation toward an intended target,
- a means for externally shading and insulating the lamp;
- a chimney configured to channel heated convective air flows through the lamp assembly, the chimney including an external vent and a side port and extending at least partially through an upper portion of the means for externally shading and insulating the lamp;
- an air gap between the means for reflecting infrared radiation and the means for externally shading and insulating the lamp, the air gap (a) defining a perimeter inlet opening extending around the means for generating infrared radiation and (b) communicating with an inside area of the chimney via the side port of the chimney, thereby defining a convective air flow path into the air gap via the perimeter inlet opening, through the air gap, into the inside area of the chimney via the side port of the chimney, and out of the head assembly via the external vent of the chimney;
- and
- a support arm mechanically connected to the base and the lamp assembly, wherein the support arm moveably supports the lamp.
