ATT O N EYS United States Patent 3,052,790 RADIANT HEATER Thomas W. Diehl, 7350 E. 24th St., Tyler M. Harkreader, 1534 E. 35th Place, and Samuel A. Chalmers, 5808 S. Quebec, all of Tulsa, Okla.

Filed Nov. 9, 1959, Ser. No. 851,606 2 Claims. (Cl. 219-3 4) This invention relates to improved applications of radiant heat as applied to localized areas.

Therefore an object of the present invention is the principle of attachment of the heating unit to the inside of the back panel of a desk well or the frame of a desk, table or bench to provide concentrated and localized radiant heating on floor areas for warmth of feet and legs.

Another object is to provide an electric switch or rheostat to either be attached to a desk, table or bench or left unattached as desired to control the heat and turn off the unit.

Still another object of this invention is to help prevent colds and other related sickness caused directly or indirectly from cold floors and drafty areas.

Another object of the invention is to provide safety by attaching the heating unit to a desk, table or bench and thus removing a dangerous object from the floor.

Another object of the invention is to remove the heating unit from the floor area to simplify building maintenance.

Another object of the invention is the use of low wattage elements so that several units can be used at the same time on the same circuit without creating a fire hazard through overloading electrical wiring.

Other and further objects of the invention will appear in the course of the following description.

In the accompanying drawing, which forms a part of the instant specification and is to be read in conjunction therewith, an embodiment of the invention is shown with like numerals used to indicate like parts.

The sole figure of the drawing is a perspective View of a radiant heater embodying the instant invention with major component parts numerically set forth.

Referring to the drawing, the radiant heater consists of a parabolic (11) reflector shell formed around two (2) ends in which is housed a heating element 1. The heating element 1 is suspended between two insulating ceramic stand-offs 4 by two terminals 6 through which two threaded rods extend to and through the parabolic (11) reflector shell. Terminal wires within the shield 13 lead from the threaded rods 5 to the pronged fitting 9. An extension cord 12 leads from the pronged fitting 9 through the switch or rheostat that is attached to a desk, table or bench or left free as required. The radiant heating unit is suspended from two adjustable Wings 7 allowing directional focusing of the heating unit through a 180 degrees are by pivoting on two rivets 14 that attach the wings 7 to the ends 2, as well as lowering or raising the heating unit on the two rods 8 that pass through the wings 7 and connect to a desk, table or bench. A removable guard 3 fits into the front of the reflector shell 11.

Thus it will be seen that there has been provided a radiant heating unit to be mounted within the well of a desk or attached to the frame of a desk, table or bench with a manual or rheostat heat control attached to a desk, table or bench, or left unattached as required.

From the foregoing it will be seen that this invention is one well adapted to attain all the ends and objects hereinabove set forth, together with other advantages which are obvious.

It will be understod that other applications are of utility and not completely set forth. This is contemplated by and is within the scope of the claims.

As many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all materials hereinbefore set forth or shown in the drawing are to be interpreted as illustrative and not in a limiting sense.

Having described our invention, we claim:

1. A radiant heater for adjustably mounting on a flat surface, comprising, in combination;

a rectagonal parabolic reflector;

a first and second end section supported to and closing at the ends thereof said reflector;

an electric heating element mounted within the confines of said reflector and said end sections;

a first mounting member pivotably supported to said first end section and a second mounting member pivotably supported to said second end section, each of said mounting members having a pair of wing portions integrally formed in a spaced relationship with each other, said wing portions extending at an angle to the length of said reflector and each of said wing portions having an opening therein;

a first and second rod support member, each of said rod members having integral end portions extending substantially perpendicularly thereof, said first rod support member received by said openings of said pair of wing portions of said first mounting member and, in like manner, said second rod support member received by said openings of said pair of wing portions of said second mounting member, whereby said wing portions at the openings thereof engage said rod support members to positionably support said reflector to said rod support member;

and means at the end portions of said rod support members to support said rod support members to said flat surface.

2. A radiant heater according to claim 1 including means of maintaining said reflector in predetermined pivotal positions relative to said mounting members.
