Description of the Invention
The invention concerns heaters for benches, particularly benches on which athletes or the like may sit, such as substitute players waiting to go in the game.
In the preferred embodiment, the heat is developed by a self-contained heater provided with a blower, such as a construction heater which is desirably placed behind the bench. The heat developed is then conducted by a conduit, desirably a 9 inch conduit, into the space under the bench, from which it is carried through a T in the conduit to discharge at two points into the space below the bench.
The space below the bench is substantially closed on the bottom, front, back and sides, except for distribution openings by which the heat is distributed to personnel in and around the bench. These distribution openings are on the top toward the back of the bench, and also in the front of the bench, such as the top of the front of the bench and the bottom of the front of the bench.
Some of the athletes sitting on the bench may have trouble through failure to heat their toes, and for this purpose openings into the interior of the bench are provided at the lower level in the back of the bench. Also pliable tubes are provided to conduct heat, for example to the neck, face and head of the user.
These openings desirably have covers and may be optionally opened.
In adapting the invention to use on the benches in tiers, the source of heat is distributed continuously with the benches at intervals along them.
The drawings bring out the invention by exemplified embodiments.
FIG. 1 is a perspective of a bench, heater and connecting conduit.
FIG. 2 is a section through the bench conduit and heater.
FIG. 3 is a fragmentary back view of the bench.
FIG. 4 is a top plan view partly in section.
FIG. 5 is a plan section of an alternate form.
FIG. 1 shows a bench of the type used by athletes while waiting for substitutes. The bench is preferably about one foot and a half high, 10 inches or so deep and about 15 feet long, although of course the specific requirements will be varied. It may have a back rest. The part that the athlete sits on may be made of wooden planks, say 2 inches or so thick, while the front, back and sides of the lower part are preferably formed of plywood joined in the form of a box, which rests on the ground or concrete and is preferably bottomless. The lower part may be made of plywood of 1/2 inch or thicker and the backrest may be of plywood such as one inch plywood.
The means of generating the heat is preferably by combustion, although it may be generated by electric resistance heating. Well known units for generating heat are the self-contained combustion heaters which contain a burner and also a blower and which produce a blast of warmed air through for example a 9 inch conduit.
These heaters have substantially 100 percent combustion and may be used in spaces requiring heat, such as warehouses and construction shacks.
In the preferred form a combustion heater 20 is used having a blower which produces heated air under pressure blown through a conduit 22 into a T conduit 23 under the bench.
The bench has a back 24, two ends 25, a front 26, and a top 27. It has an optional back rest 28.
At the back of the top of the bench, there are slots 30, which are covered with closures 31, preferably of the sliding type. In the front of the bench there are a slot 33, preferably about the front corner and a slot 32 at the bottom of the front, preferably provided with a removable cover.
In an optional form, such as is suited to benches in tiers which must be heated, the heaters 20' are arranged continuously with the benches at intervals along the benches, and they discharge at intervals under the benches corresponding to the intervals at which the T-conduit discharges.
In wearing football shoes, the toes of the wearer may be susceptible of becoming cold and the wearer may want therefore a place to warm his toes. Openings 40 are provided covered by flaps 41 in the back of the bench, so that athletes or others could insert the tips of the shoes in the holes. This is spring loaded and preferably a flop hinge.
At times the athletes or others may desire to have the neck, face or head heated and for this purpose flexible tubes 43 are made available, cut off by valves 44. This may also be used to warm the hands, particularly of a substitute player who may have to throw a pass or catch a pass if he is put in the football game.
While the use by football teams is particularly pleasing, the invention may also find use, for example, for spectators of parades, such as the Philadelphia Mummer's Parade and especially for broadcasters who are broadcasting such parades.
It will be evident of course that on the conduits and the like which convey heat, insulation may be useful or even essential.
In view of my invention and disclosure, variations and modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art, to obtain all or part of the benefits of my invention without copying the device shown, and I therefore claim all such insofar as they fall within the reasonable spirit and scope of my claims.
