Abstract
Abstract Infrared-radiating equipment having ceramic radiators and reflectors. Any desired number of uniform reflectors are hinged to each other at their longer sides and articulated with bearing bolts. Enough radiators to attain the desired heating effect are accommodated next to each other in a common reflector. The radiators are preferably rod-shaped or rectangular.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
231 words
Infrared-radiating appartus comprising: ceramic radiators; reflectors supporting said radiators; hinged joint means at edges of said reflectors and having sleeve means; and connecting pin means passing through said sleeve means for hingedly interconnecting a plurality of reflectors to form a predetermined geometrical shape supporting said radiators in a predetermined arrangement; said reflectors having sloping walls connected to a correspondingly wide rear portion; said rear portion having groups of openings for mounting said radiators; said reflectors having auxiliary openings for passing power lines of said radiators; said sleeve means comprising sleeve members mutually displaced at a distance from each other so that sleeves of another reflector can be inserted therebetween to form a hinged connection between a plurality of reflectors; rod-shaped members inserted through said sleeves for assembling a plurality of reflectors in sequence; reflectors being connectable hingedly next to and behind each other; said radiators comprising elongated rectangular elements having a ceramic body with heat conductors embedded therein and terminating into power-supply lines at ends of said radiators; said radiators having supports comprised of ceramic material; attaching connecting wires being passed through said supports; each radiator having two supports on its rear surface; said attaching connecting wires being passed through openings in said reflectors and being twisted together in back of the reflectors; and power-supply lines passed through said auxiliary openings and connected to electric terminals in back of said reflectors.
Claim 2
Dependent Claim
231 words
Infrared-radiating appartus comprising: ceramic radiators; reflectors supporting said radiators; hinged joint means at edges of said reflectors and having sleeve means; and connecting pin means passing through said sleeve means for hingedly interconnecting a plurality of reflectors to form a predetermined geometrical shape supporting said radiators in a predetermined arrangement; said reflectors having sloping walls connected to a correspondingly wide rear portion; said rear portion having groups of openings for mounting said radiators; said reflectors having auxiliary openings for passing power lines of said radiators; said sleeve means comprising sleeve members mutually displaced at a distance from each other so that sleeves of another reflector can be inserted therebetween to form a hinged connection between a plurality of reflectors; rod-shaped members inserted through said sleeves for assembling a plurality of reflectors in sequence; reflectors being connectable hingedly next to and behind each other; said radiators comprising elongated rectangular elements having a ceramic body with heat conductors embedded therein and terminating into power-supply lines at ends of said radiators; said radiators having supports comprised of ceramic material; attaching connecting wires being passed through said supports; each radiator having two supports on its rear surface; said attaching connecting wires being passed through openings in said reflectors and being twisted together in back of the reflectors; and power-supply lines passed through said auxiliary openings and connected to electric terminals in back of said reflectors.
Claim 3
Dependent Claim
183 words
Infrared-radiating apparatus comprising: ceramic radiators; reflectors supporting said radiators; hinged joint means at edges of said reflectors and having sleeve means; and connecting pin means passing through said sleeve means for hingedly interconnecting a plurality of reflectors to form a predetermined geometrical shape supporting said radiators in a predetermined arrangement; said reflectors having a portion with groups of openings for mounting said radiators; said sleeve means comprising sleeve members mutually displaced at a distance from each other so that sleeves of another reflector can be inserted therebetween to form a hinged connection between a plurality of reflectors; rod-shaped members inserted through said sleeves for assembling a plurality of reflectors in sequence; reflectors being connectably hingedly next to and behind each other; said radiators comprising elements having a ceramic body with heat conductors embedded therein and terminating into power-supply lines at ends of said radiators; said radiators having supports comprised of ceramic material; attaching connecting wires being passed through said supports; said attaching connecting wires being passed through openings in said reflectors; and power-supply lines connected to electric terminals in back of said reflectors.
Claim 4
Dependent Claim
183 words
Infrared-radiating apparatus comprising: ceramic radiators; reflectors supporting said radiators; hinged joint means at edges of said reflectors and having sleeve means; and connecting pin means passing through said sleeve means for hingedly interconnecting a plurality of reflectors to form a predetermined geometrical shape supporting said radiators in a predetermined arrangement; said reflectors having a portion with groups of openings for mounting said radiators; said sleeve means comprising sleeve members mutually displaced at a distance from each other so that sleeves of another reflector can be inserted therebetween to form a hinged connection between a plurality of reflectors; rod-shaped members inserted through said sleeves for assembling a plurality of reflectors in sequence; reflectors being connectably hingedly next to and behind each other; said radiators comprising elements having a ceramic body with heat conductors embedded therein and terminating into power-supply lines at ends of said radiators; said radiators having supports comprised of ceramic material; attaching connecting wires being passed through said supports; said attaching connecting wires being passed through openings in said reflectors; and power-supply lines connected to electric terminals in back of said reflectors.
