Definitions

  • the invention relates to a multi-purpose bathtub comprising a bath container passing into an edge plate and also containing a bottom and a cover containing two sidewalls situated opposite each other and passing on the one end of the bath container into a lean-back wall, and on the opposite end of the bath container, into a foot wall while the cover of the bath container passes on its lower side into the bottom of the bath container
  • bathtubs are made as longitudinal containers with a flat or deflected non-articulated bottom and with sidewalls featuring a more or less complex shape
  • the flat bottom of the bathtub permits to use it also for taking the shower since the risk of slipping on the damp and relatively smooth surface of the flat bottom is sensibly inferior to that in a bathtub with deflected bottom
  • the flat or even deflected non-articulated bottom of the bathtub involves considerably high water consumption if the person having a bath wishes to be immersed under the water level with the whole of their body
  • the person having a bath especially a person whose ability to move has been reduced by age, illness or accident, finds it difficult repeatedly to sit down and to stand up in the bathtub with a flat or even deflected not-articulated bottom
  • the frequent disproportion between the height of the person having a bath and the length of the bathtub with flat or even deflected bottom renders it difficult for the person to take up the most convenient relaxation position
  • the problems of the persons having a bath connected with the movements of standing up and sitting down in a bathtub are dealt with in the published patent application DE OS 41 23 635 describing a bathtub with articulated bottom of the bath container and articulated lean-back surface for the back of the person having a bath, said lean-back surface being continued as a head rest for the person having a bath
  • the bottom of the bath container comprises a sitting surface slightly raised above the basic surface of the bottom of the bath container
  • the basic surface of the bottom of the bath container is the lowest surface of the bath container and passes at the side opposite to said lean-back surface into a foot support surface oriented obliquely upwards
  • the foot support surface then passes into a horizontal lean surface for heels of the person sitting in the bathtub with stretched out legs
  • the horizontal lean surface for heels passes into the cover of the bath container Situated on the upper edge of the bath container is a grip helping the person having a bath to sit down and to stand up
  • Another drawback consists in that even after assuming the partly lying relaxation position not all body muscles are relieved because the legs of such a partly lying person lean only in the upper portion of the thighs and on the heels and feet which is not sufficient for relieving all body muscles
  • Still another drawback consists in the big volume of the bath container necessarily involving increased water consumption when having a bath with the whole body immersed under the water level
  • the published patent application PCT/US91/06910 describes a bathtub with articulated walls and complements
  • the bathtub according to this invention comprises two articulated sidewalls situated opposite each other and passing into two mutually opposite situated articulated lean-back surfaces, each of them comprising a head rest, with the lower part of the cover of the bath container passing into the bottom of the bath container
  • One of the sidewalls carries a grip to help the person having a bath to move
  • the bath container also contains a set of massage nozzles seated in the walls of the cover of the bath container
  • the invention aims at doing away with, or at least at minimizing, the drawbacks of the state of art
  • a multi-purpose bath container whose principle consists in that the bottom of the bath container contains in the direction from the lean-back surface of the bath container to the heel wall of the bath container a sitting section passing into an upwards sloping middle part which in its turn passes into a heel part
  • This invention reduces the water quantity required for immersing the whole body of the person having a bath under the water level, and also permits to take up a more convenient relaxation position relieving all muscles of the whole body
  • the heel part of the bottom is oriented obliquely upwards, and its angle of inclination with the horizontal plane is inferior to the angle of inclination of the middle part of the bottom with the same plane
  • the mutual distance between the two sidewalls decreases in the direction from the lean-back wall to the heel wall, thus further reducing the quantity of water required for immersing the whole body of the person having a bath under the water level
  • the longitudinal symmetry plane of the bath container makes with the longitudinal symmetry plane of the edge plate an acute angle different from zero which permits to increase the length of the bath container without increasing the length of the edge plate and thus to use the bathtub even in relatively small rooms
  • the longitudinal symmetry plane of the bath container makes with the longitudinal symmetry plane of the edge plate such an acute angle different from zero that one of the sidewalls of the bath container is parallel with its adjoining lateral edge of the edge plate thereby increasing the surface of the edge plate on the opposite side of the bath container which promotes the creation of a rest surface or of a sitting surface
  • the bottom of the bath container contains a tread surface for having the shower situated in the plan view between the transition of the lean-back wall to the sitting section of the bottom of the bath container and the heel wall, with at least a part of the tread surface for taking a shower passing into a circumference wall, the latter in its turn passing into the respective walls of the bath container and/or into the edge plate
  • the shape and position of the tread surface preferably may be modified as needed
  • the tread surface for taking a shower is in the plan view preferably situated between the longitudinal symmetry plane of the bath container and one of the side edges of the edge plate, said side edge of the side plate being in plan view concurrent with its adjoining sidewall of the bath container which provides for a width of the respective surfaces of the bottom of the bath container sufficient to permit the person having a bath to take up a convenient relaxation position
  • At least a part of the tread surface protrudes outside the edge plate in the direction outside this edge plate thus additionally increasing the width of the respective bottom surfaces and by means of this also the convenience of the person having a bath in its relaxation position
  • the tread surface for taking a shower is the lowest surface of the bath container thus permitting to obtain between the tread surface, the other walls of the bath container, and the edge plate level differences suitable for good water flow-off
  • the tread surface for taking a shower permits to use the multipurpose bathtub also for taking a shower Unlike the current types of bathtubs, it reduces to a minimum the risk of slipping and injury when taking a shower
  • Suitable level differences between the respective surfaces of the bath container may be advantageously used by the persons having a bath to sit down to, and to stand up from, the relaxation position
  • Persons with reduced movement ability can sit down without risk, for instance on the heel part of the bottom of the bath container with the feet put on the tread surface for taking a shower, and can then easily and securely move to the relaxation position with the whole body immersed under the water level, or they can have a shower in a sitting position, and can then more easily and securely stand up and securely get out of the bathtub
  • a part of the tread surface for taking a shower passing into a sidewall of the bath container and/or into the respective edge plate is preferably fitted with a grip
  • the bath container is fitted with a set of massage nozzles situated, preferably in recesses, in the bottom or in the respective walls of the bath container so as to obtain turbulent streams in said recesses and thus to increase the relaxation effectiveness of the massage nozzles, further supported by the ergonometncally shaped bath container, on the person having a bath in this multi-purpose bathtub
