Definitions

  • the reclining section including a reclining, flexible heating surface having a layer of electrically conductive heating material, insulating layers enclosing said electrically conductive layer, and electrical contacts connected to said heating material for electrical connection to live voltage or a battery.
  • the heating material having a positive temperature coefficient of electrical resistance to minimize voltage supply requirements and to provide current limitations.
  • This invention relates to electrically heated furniture and is described in terms of a chair structure, more specifically a heated reclining chair.
  • the heating of the reclining section is accomplished with a surface heat conducting unit which reduces only slightly the flexibility of the body supporting or reclining structure.
  • the heating unit can be built integrally in the reclining surface, or the reclining surface can be treated to serve as a heat conductor.
  • FIGS. 1 and 2 are isometric views which illustrate linebattery-energized embodiments
  • F IG. 3 is a plan schematic view of the and FIG. 4 is a sectional schematic view through the reclining section on an enlarged scale.
  • H0. 1 shows a deck chair which except as noted hereinafter is of customary construction. Assembled in the reclining section 1 is an electrically heatable surface heating unit. On the bottom of the deck chair a socket 7 (FIG. 3) is attached, the socket being connected with the surface heating unit by electric wiring as described hereinafter. In the socket a plug 12 with a flexible extension cable 13 has been inserted, the latter serving as a connection to a source of electric current.
  • FIG. 2 illustrates a battery-powered embodiment of the invention.
  • the transverse rods 2 of the chair are of hollow cylindrical shape and serve to receive the battery, e.g., the cell 3.
  • the principal component of the heating arrangement is the surface heating unit 4, which is shown in FIG. 3. It can advantageously consist of a carrier material consisting of a synthetic material, e.g. Teflon, which has been treated to be heat conductive. Suitable techniques and compositions for this purpose have been reported in the literature and published patents. See for example, Swiss Pat. No. 456,741 as shown therein, the resistance material can preferably be made from nonpolar plastic materials including polyolefins, e.g., polypropylene, polyethylene, polybutene or mixtures thereof. Polyvinylchloride and lupolen can also be used. Dispersed in the nonconductive component may be graphite or carbon black.
  • the surface heating unit is flexible and preferably substantially coextensive with the entire reclining surface or actually constitutes the reclining surface.
  • the resistance value of these conductive layers may be selected such that the heating can be carried out with voltages not exceeding lethal values, e.g., voltages less than 65 volts. ln this case the special precautions required to avoid shock are not necessary.
  • lethal values e.g., voltages less than 65 volts. ln this case the special precautions required to avoid shock are not necessary.
  • alternating current via stepdown transformers (e.g., one which reduces the mains voltage to say 42 volts), or direct current, from batteries e.g. cells supplying 6, 12 or 24 volts.
  • stepdown transformers e.g., one which reduces the mains voltage to say 42 volts
  • direct current from batteries e.g. cells supplying 6, 12 or 24 volts.
  • surface heating unit 4 one can and surface heating unit;
  • the contact strips deposit the contact strips 5, as shown in FIG. 3, alongside the surface heating unit. This may be done for example by spraying copper to form the contacts. With these contact strips one can achieve an even distribution of current over the complete surface. Alternatively, the contact strips can be disposed over the broadside of the surface.
  • the current conductor wires 6 are welded or soldered to the contact strips 5 or connected thereto by using appropriate connectors.
  • the wires 6 are connected in turn to the socket 7. Should a low voltage be required (preferably no more than 65 volts) a suitable socket of special configuration must be provided which will not receive the customary line voltage plugs. lf batteries are used, they can be placed on the underside of the chair, e.g., in the hollow transverse rod 2.
  • FIG. 4 illustrates a cross section of the finished reclining structure.
  • the surface heating unit 4 which in this case is constructed from fabric, are copper wires 8 disposed in the selvedge to improve conductivity to the contact strips 5.
  • the surface heating unit is covered with insulating material 9.
  • the heat-insulating layer 10 is provided. in this case it consists of a synthetic material e.g., a coating of PVC or epoxy resin affixed to a rough aluminum foil heat reflector 11.
  • the insulator 10 and the foil 11, the surface heating unit 4, and insulating layers 9, are encapsulated in the fabric sections 1, which forms the actual reclining surface of the deck chair.
  • chairs according to the invention require very little electric power. Generally one needs less than 30 watts of power.
  • the chair is particularly effective for use on cold, sunny winter days. The user of the deck chair is exposed in this event to the warm sun energy on one side and the warmth of the reclining section of the deck chair on the other.
  • the invention is not to be limited to the specific examples shown and is adaptable to other seats as well including garden chairs or benches, Hollywood swings, hammocks, car seats, chair lifts and the like.
  • An article of furniture comprising a body support having a plurality of longitudinal members arranged to for man open frame, and a reclining section connected to said frame to provide a seating area within the frame, said reclining section including a reclining surface having a flexible heating section which includes a layer of electrically conductive heating material with integral temperature-responsive distributed current-limiting means, insulation means for electrically insulating said layer of heating material, and electrical contact means connected to said heating material for supplying a voltage to said material whereby said reclining section is electrically heated, said current-limiting means comprise a material having a positive temperature coefficient of electrical resistance.
  • heating surface includes a layer of spray-deposited electrical contact material connected to said heating material.
  • said layer of heating material comprises a unitary flexible plastic sheet occupying a substantial part of said reclining section.
