1. Field of the Invention
This invention relates to covers for heaters, such as stand-type gas or electric heaters, and methods of using the same. The heater can be, for example, a movable or fixed patio heater or table-top heater.
2. Description of Related Art
Typical tower heaters, such as those used for outdoor and patio use, have an appearance that is considered “industrial” and sterile by many. Some newer designs for tower heaters obstruct the typical “industrial” design, for example, providing the tower heater with the configuration of a palm tree, or other design. These alternate designs are permanently fixed to the heater. However, it is often desired to change the design of the heater without having to have separate heaters for each design or without having to incur the expense to purchase a new standup heater to change the design.
Tower heaters (e.g., patio heaters) are often used in public, residential, and commercial locales. For example, tower heaters are often located in outdoor seating areas at restaurants, in plazas, and outdoor malls; or by event planners or rental companies for functions or parties. These locations make the heaters optimum sites for advertising. However, the towers are often too thin and the heat shields of the heaters are too steep of an angle and its surface too hot to reasonably display advertising. The base is also well below eye level, so posting advertising on the base would be generally out of sight.
Therefore, replaceable and/or removable outer configuration for tower heaters is desired. Furthermore, a configuration of a heater and accompanying method for reasonably attaching a display to a tower heater is desired.
A device for camouflaging the mechanical structure of a tower (e.g., patio, outdoor) heater is disclosed. The device can be a cover or shell. The cover can have an assembly of, for example, two to four panels or “skins” or cover sections. The cover sections can be rigid or flexible. The cover sections can be rotatably attached to each other, for example via one or more rotatable hinges. The cover sections can be attached to the underlying mechanical structure of the tower heater in a “clamshell” fashion.
The cover can be constructed from one or more elements that extend longitudinally along the entire cover, or horizontally with the split occurring somewhere around the base and tower, or the cover can be made from a body cover and/or separate head cover. The body cover can have a tower cover and a separate base cover. The head cover can be a decorative “shade” or shield around the existing parabolic heat deflector (i.e., heat shield or heater head) at the top of the heater structure.
The head cover can have a cylindrical or a conical, square, polygonal, elliptical, hemispherical configuration or a partial configuration of any of the aforementioned configurations, or a combination of any of the configurations thereof. If the head cover has a conical or partial conical configuration, the angle of the cone with respect to the longitudinal axis of the heater can be from about 0° to about 45°± in either direction, more narrowly from about 0° to about 25° in either direction.
One or more displays can be attached to the heater head, tower, body, base, head cover, tower cover, base cover, body cover, or combinations thereof. The displays can have a flat or curved surface. The displays can form an angle with the longitudinal axis of the heater from about 0° to about 45°± in either direction, more narrowly from about 0° to about 25° in either direction.
The cover can be made from one or more rigid or semi rigid materials, for example thermoplastics (e.g., Polyethylene terephthalate (PET), Polyethylene (PE), Polypropylene (PP)), polycarbonates, or silicon or vinyl-base materials or EVA copolymers which may, for example, be blow, injection, or rotational molded, fiberglass reinforced polymers (“FRP” or fiberglass), resins, stamped or spun sheet metal, urethane over a formed metal structure, heat resistant fabrics stretched around a metal frame, or combinations thereof in smooth or textured finish. The material can be opaque, translucent or transparent. The cover can be made from materials that can be lightweight, suited for outdoor use, long lasting, and have a durable finish in multiple colors. The cover can be made by being molded, for example roto-molded.
The cover sections can be attached to and detached from each other with mechanical hardware, such as one or more fasteners including quick release fasteners 70, one or more piece of hook and loop tape (e.g., Velcro); one or more piece of interlocking stem and head tape (e.g., Dual Lock from 3M Corporation of Minneapolis, Minn.), magnets, latches, clips, ties, hooks, locking pins, the ports and flanges to which they are to attach, and combinations thereof, for example applied on overlapping flanges (e.g., tongue-and-groove, guide-pins, grooves) or into ports of adjacent cover sections. The fasteners 70 can be locked, hooked, pressed, snapped or otherwise joined together into place.
The cover sections can be hinged together, for example in a clamshell fashion.
The cover sections can have horizontal seams. The horizontal seams can divide the cover sections into two or more section that can telescope or separate when moved relative to each other in a vertical direction. For example, a lower section can slide upwards, and may temporarily come to rest on the tinder structure of the patio heater column to gain access, for example, to the propane tank area, for example to service the propane tank area or replace the propane tank. The cover sections can be simply and repeatedly assembled, disassembled, and easily transported between locations, or stored by nesting the cover sections together.
The covers can have fluting or grooves, textures, appliqués, self-adhesive tape, and combinations thereof. For example, these features (e.g., fluting/grooves, textures, decorative rings, etc.) can hide joints between the cover sections while providing aesthetic design alternatives.
The head cover sections can be punctured, louvered, folded, made of metal mesh, or otherwise treated, for example to dissipate and/or collect and/or direct heat and/or to provide alternate aesthetics.
The head cover sections can be attached to and detached from the tower, head and base of the heater. The head cover sections can have or be attached to straps or spokes. For example, two to four or three to six straps or spokes can radially extend from the center of the heater. The straps or spokes can attach to the cover section (e.g., the head cover or the body cover). Mechanical quick-release fasteners 70 can attach the cover sections to the heater head or body (e.g., tower or base). The fasteners 70 can thermally insulate the cover sections from the heater head or body. The thermal insulators can be spacers and/or a layer of thermal insulating material.

The head cover 22 can have a head cover slope 32 less than 0°. The sign 72 on the head cover 22 can be tilted downward, upward, or perpendicular to the ground. The sign 72 on the body cover 24 can be tilted downward, upward, or perpendicular to the ground.
As shown in
Corresponding fasteners 70 on the heater cover 20 and, where applicable, the uncovered heater 2 can be fastened after the heater cover 20 is positioned on and/or around the uncovered heater 2.
The cover first section 82 can be completely separate (e.g., not attached at a hinge 64) from the cover second section 84 before use. The cover first section 82 and cover second section 84 can be translated in a position to together surround the body 4. Fasteners 70 on the cover first section 82 can then be attached to fasteners 70 on the cover second section 84.
Any or all parts of the heater cover 20 can have horizontal and/or vertical ridges 210, ribs or grooves. The ridges 210 on the body cover 24 can align to the ridges 210 on the tower cover 36.
During assembling and attaching of the tower cover 36 to the body cover 24, the tower cover 36 can be snap-fitted, glued (or other adhesive, epoxy), attached via one or more pieces of hook and loop tape (e.g., Velcro); one or more pieces of interlocking stem and head tape (e.g., Dual Lock from 3M Corporation of Minneapolis, Minn.), attached via a pressure collar, or used with any fastener listed herein or combinations thereof to or from the body cover 24. Once assembled, the seam 48 can be substantially horizontal.
For example, a propane or other liquid or gas fuel tank and/or electrical power supply and controls can be stored inside the body cover 24. For example, to access (e.g., for service or replacement) the propane tank and/or power supply and controls, the body cover 24 can be detached from the tower cover 36 and the body cover 24 can then be lifted above the propane tank and/or power supply and controls for rapid access. The tower cover 36 can be permanently or semi-permanently attached to the heater column 10 or removed during the accessing, for example, of the propane tank under the cover 24.
a through 32d illustrate a variation similar to that shown in
The tower cover 36 can be fixed or separably attached to the tower 10. For example, the tower cover 36 can be attached to the tower 10 via brackets, clamps, hooks, or combinations thereof internal to the tower cover 36. The base cover 34 can be separate and unattached from the tower cover 36 and the tower 10. The base cover 34 can be attached or unattached from the base and/or tower. A joiner, such as a ring, can have serve merely to hide or obscure the seam 48 between the base cover 34 and the tower cover 36 and not to join the tower cover 36 to the base cover 34.
For example, the tower cover 36 and the base cover 34 can be made as a single unit, then cut above, below, or through the ring at the joint 38 to separate the tower cover 36 and the base cover 34.
The inner diameter of the base cover 34 at the joint 38 can be larger than the outer diameter of the tower cover 36 at the joint 38. The minimum inner diameter of the base cover 34 can be larger than the maximum outer diameter of the tower cover 36.

The base cover 34 can be raised, as shown by arrows, for example to expose the contents of the base 8. For example, the base cover 34 can be slid or otherwise lifted at least partially vertically concurrent with the tower cover 36. The base cover 34 can be radially inside or outside of the tower cover 36. The base cover 34 can be lifted above the tower cover 36. The base 8 can include a propane or other fuel tank or controls. The base cover 34 can be moved temporarily to a position around a part or all of the length of the tower cover 36.
The contents of the base 8 can be accessed, for example, the fuel tank can be serviced or replaced. The base cover 34 can then be lowered to the position shown in
The tower cover 36 can be configured to be slidably or otherwise lowered at least partially vertically concurrent with the base cover 34. The tower cover 36 can be lowered to the ground.
The base cover 34 can be configured to be not directly attached to the base. For example, the base cover 34 can be resting freely on or anchored to the ground and/or pressed down by or attached to the tower cover 36 when the base cover 34 is in a position encircling the base. The tower cover 36 can be configured to be not directly attached to the remainder of the tower. For example, the tower cover 36 can be resting freely on or attached to the base cover 34.

The shaft 116 can be inserted through ports in the first panel 106 and/or the second panel 108, and/or the shaft 116 can bore through the first panel 106 and/or the second panel 108. The shaft 116 can be oriented at a perpendicular, near perpendicular or slight perpendicular angle to the seam 48.
In one variation, three fasteners 70 can be used on each side of the body cover 24 (i.e., six total fasteners), for example one near the top of the body cover 24, one near the middle of the body cover 24, and one near the bottom of the body cover 24.
A retainer clip 160 can be attached to or integral with the shaft body 161 and/or placed between the first panel 106 and the second panel 108 and the fastener 70 can be inserted through the retainer clip 160.
The fastener 70 can have a handle 166 rotatably attached to the shaft head 111. The handle 166 can be used to rotate and push and pull the fastener 70 directly by hand. The handle 166 can be rotated, as shown by arrows 167 in
The shaft 116 can be attached to or integral with a spring 168. The spring 168 can slidably rest against the side of the second panel 108. The shaft 116 can have threads 132. The shaft 116 can be threadably attached to the first panel 106, and/or second panel 108, and/or the retainer ring 164. The shaft 116 can be rotated, for example, screwing the shaft 116 to increase compression of the spring 168 between the end of the shaft 116 and the second panel 108.
The body cover 24, head cover 22, fasteners 70, or other elements described herein can be made from thermoplastics (e.g., Polyethylene terephthalate (PET), Polyethylene (PE), Polypropylene (PP), including those used in rotational or blow molding) one or more fiber-reinforced polymers (e.g., FRP, fiberglass), resin, sheet metal (e.g., stamped sheet metal), urethane, heat resistant fabrics (e.g., stretched around a steel frame or other structure), or combinations thereof.
