Definitions

  • This invention relates to a device for displacement of liquid, particularly water in a storage vessel such as a bath or pool.
  • Inflatable devices designed for use in baths are also known. Typically, such devices take the form of inflatable chairs designed to assist elderly or infirm in entering or exiting a bathtub.
  • UK Patent Application GB-A-2 322 798 discloses a solid device which is filled with water and is designed to permanently occupy a proportion of the bath space. Such devices are uncomfortable for the user, and often lack flexibility of application.
  • US Patent US 5 896 598 discloses an inflatable seat which is equipped with a mechanical inflation means, and is designed to assist a person in getting into a bath and then to be deflated once the user has entered the bath, thus negating any water-saving properties.

  • the device As the device can be deflated, it is dimensioned and arranged so that it can be packed away into a relatively small package (deflated volume compared with when inflated) and so can be readily delivered to end users and by post.
  • the displaceable volume may be relatively small, that is less than 1 litre and even smaller than say 150 ml. Additionally a plurality of displaceable devices may be provided.
  • the device may be produced as a basic modular version with suitable spaces or voids shaped and dimensioned to receive add on components, such as updates with new features.
  • the displaceable device may have indicators showing how much liquid is displaced.

Abstract

L'invention concerne un dispositif de déplacement de liquides (3, 13, 23, 33, 43, 53, 63, 73) qui comprend un ou plusieurs contenants gonflables (3, 13, 23, 233, 338, 336, 43, 53, 63, 66, 67, 73, 74), et un accessoire (4, 14, 24, 34, 45, 55, 65, 66, 75) pour fixer le dispositif de déplacement de liquides à un récipient de stockage de liquides (1). Quand il est gonflé et fixé à une surface intérieure (11) du récipient de stockage de liquides (1), le dispositif de déplacement de liquides déplace le liquide dans le récipient de stockage de liquides. Lesdits un ou plusieurs contenants (3, 13, 23, 23a, 33a, 33b, 43, 53, 63, 66, 67, 73, 74) peuvent se trouver entièrement ou en partie en dessous de la surface (2) du liquide à l'intérieur du récipient de stockage de liquides (1). L'accessoire comprend une attache (66) ou un moyen d'aspiration (4, 14, 24, 34, 45, 55, 65, 75) tel que des ventouses. Le contenant comprend un seul compartiment (3, 13, 53, 63), ou plusieurs compartiments (23, 23a, 33a, 33b, 43, 66, 67, 73, 74) raccordés de sorte qu'un gaz puisse circuler entre eux. Le dispositif peut être un jouet comprenant un compartiment de stockage (35, 50, 68).
