  • N0.Z 323,258 57 ABSTRACT A device adapting an existing domestic bathtub for [30] Foreign Application Priority Data steam or dry hot-air bath comprising a base frame- Jan. 14, 1972 Japan 47-6321 work, an end plate hinged to Said framework, a etachable cover member positioned over said frame- [52] US. Cl. 4/162, 4/160 rk an nd pla having openings adjacent the 0p- [51] Int.
  • the conventional domestic bathtubs have been exclusively employed for hot-water bathing and if a-person desires to have a steam or hot dry air bath at home, usually, he has been obliged to have a paricular bathtub specifically designed for such a purpose. If any existing domestic bathtub is converted to a steam or dry hot-air bath, such conversion requires a lot of labor and many accessary parts resulting in increasement in cost.
  • a principal object of the present invention is to provide a device which adapts an existing domestic bathtub for steam or dry hot-air bath by simply modifying the existing domestic bathtub at less expense.
  • Another object of the present invention is to provide a device which adapts an existing domestic bathtub for steam or dry hot-air bath and which is easily and readily attached to and detached from the existing domestic bathtub.
  • a further object of the present invention is to provide a device which adapts an existing domestic bathtub for steam or dry hot-air bath by the utilization of a conventional electric heater.
  • FIG. I is a perspective view of an existing domestic bathtub on which a device according to the present invention is mounted showing the bathtub is in its closed or non-use state;
  • FIG. 2 is a side elevational view of said bathtub of FIG. 1 showing it operation state with the dot-chain line and the non-use state with the full line;
  • FIG. 3 is a vertically sectional view of said device shown in FIGS. 1 and 2;
  • FIG. 4 is a perspective view of said device with the cover member thereof removed therefrom to show the interior of the device;
  • FIG. 5 is similar to FIG. 4, but shows the device in its folded state
  • FIG. 6 is a perspective exploded view on an enlarged scale of a heater to be employed in conjunction with the device of the invention.
  • FIGS. 1 and 2 thereof in which an existing domestic bathtub 10 is shown as having'the device 12 of the invention detachably mounted thereon.
  • the dev-ice 1 2 generally comprises a U-shaped base framework 14 having a U-shaped downwardly extending flange (not shown) which is positioned inwardly of and spaced from the peripheral edges of the framework and adapted to be fitted in the open top of the bathtub.
  • the base framework 14 has an end plate 14a hinged to the inner end of the framework 14 and the end plate also has a U-shaped downwardly extending flange 14b which is positioned inwardly of and spaced from the peripheral edges of the end plate to be fitted in the open top of the bathtub.
  • Props 16 are provided on the upper surface of the base framework 14 in spaced positions and the props extend uprightly at right engles to the plane of the base framework 14.
  • the base framework 14 and end plate are normally covered by a cover member 15 which inclines downwardly from the outer end of the base framework 14 toward the inner end of the framework.
  • the end plate 14a has a rectangular opening 17 in the center thereof and the cover member 15 is also provided with a similar rectangular opening 18 in alignment with the opening 17 for the purpose to be described hereinbelow.
  • An air heating or steam generating assembly 19 is detachably mounted on the end plate 14a with the lower portion of the assembly detachably received in the openings in the end plate and cover member for heating air or generating steam and recycling the same within the space defined by the bathtub and cover member.
  • the base framework 14, end plate 14a and props 16 may be formed of a metal such as aluminum alloy or stainless steel or synthetic resin of thermostability or thermoresisting property.
  • the props 16 may be integrally formed with the base framework 14 or separate parts.
  • the cover member 15 may be formed of a rather thick synthetic resin sheet and as shown in FIG. 1, the cover member has a cut longitudinally extending between the opposite ends of the cover member to provide an access opening through which the body of a person who is subjected to hot-air or steam treatment may go into or out of the bathtub 10.
  • the cover member 15 also has a circular opening 20 adjacent the outer end through which the head of the person whose body is received within the bathtub 10 may be exposed to the outer air.
  • the opening 20 is normally closed by a lid 21 a part of which is suitably secured to the cover member 15 for manual opening or closing.
  • the cover member 15 is provided in its outer periphery with a plurality of spaced lock means 22 which sealingly engage the periphery of the base framework 14 and end plate 14a to seal the bathtub when the cover member is placed in position.
  • the cut in the cover member 15 is provided with a slide fastener 23 to slidably move along the cut for closing or opening the cut. Although only one cut is provided in the cover member 15 in the illustrated embodiment, two cuts may be provided in the cover member without departing from the spirit of the invention so that the body of the user may be more easily received into and taken out of the bathtub 10.
  • the air heating or steam generating assembly 19 is itself of a conventional construction and does not constitute any part of the present invention. However, since the present invention utilizes the function of the assembly, the construction and operation of the assembly will be briefly described herein.
  • the air heating or steam generating assembly 19 is illustrated in the form of an electric heater.
  • the heater 19 is operated with electric power supplied from a suitable power source (not shown) through a conductor 24 and comprises a housing 25, an electric motor 26 housed in the housing and mounted on a support plate 27, a fan 28 operatively connected to the motor 26 to be driven thereby and a heating element 29.
  • a suitable power source not shown
  • a fan 28 operatively connected to the motor 26 to be driven thereby and a heating element 29.
  • actuating switch button 30 Provided on the top of the housing 25 are an actuating switch button 30 and a pilot lamp 3].
  • the pilot lamp 31 which is electrically connected to a suitable thermosetting element (not shown) for adjusting the temperature of air is lit up thereby to rotate the fan 28 through the motor 26 and heat the heating element 29.
  • a suitable thermosetting element not shown
  • the air in the space defined by the bathtub and cover member is circulated by the fan 28 passing through the now heated element 29 to incrementally increase the temperature of the air in the space. In about to 30 minutes after the initiation of the operation on the heater, the air temperature will be increased to a desired level suitable for the desired treatment whereupon the pilot lamp 31 momentarily lights out to indicate that the air temperature has reached to the desired level.
  • a device adapting a domestic bathtub for steam or dry air bath comprising a U-shaped base support framework, an end plate hinged on one side to the open end of said framework, a plurality of props formed with said framework projecting uprightly therefrom, a cover member detachably positioned over said framework and end plate to define a treating space between the cover member and bathtub, said cover member having a first opening adjacent one end through which. the head of a user may project to be exposed to the outer air, a second opening adjacent the other end, a longitudinally extending slit opening between said first and second openings, a slide fastener arranged to open and close said slit opening, and a heater detachably mounted in said second opening of the cover member.
  • said cover member further has a plurality of lock means for sealingly engaging the peripheral edges of said framework and end plate to hold the framework and end plate in position.
