Definitions

  • This invention relates to waterbeds, and in particular to waterbed mattresses.
  • Waterbeds in the past have usually been made with a mattress consisting of a large, watertight bladder covered by mattress ticking, and a heavy supporting structure or frame to maintain the shape of the mattress and support the heavy weight of the water filling the bladder.
  • a difficulty with this type of waterbed is that it cannot be moved without draining the mattress, and in view of the large quantity of water, this is time-consuming and wasteful since the water is usually not re-used.
  • a further difficulty with these waterbeds is that a leak in the bladder can cause extensive damage.
  • a flotation mattress pad for a bed comprising a rectangular inner bladder constructed from an impervious plastic material having a top side and bottom side with coterminous peripheral edges which are heat sealed to each other in order to form a fluid-tight enclosure.
  • the top side has a valve.
  • a rectangular outer bladder is constructed from a fluid impervious plastic material having a top side and a bottom side with coterminous peripheral edges heat sealed to each other in order to form a fluid- tight enclosure which encloses the inner bladder.
  • the top side of the outer bladder has an opening which is positioned to surround the valve on the inner bladder and allow access thereto.
  • a mattress cover for a flotation mattress pad.
  • the cover comprises an upper side which is constructed of mattress ticking having a thermal barrier layer, and a bottom side and peripheral sides, both made of a woven cloth fabric.
  • the cover is provided with an elongate zippered opening in order to allow the insertion of outer and inner bladders and the filling thereof.
  • FIG. 1 is perspective view of a flotation mattress pad having two inner bladder assemblies
  • Fig. 2 is an enlarged sectional view of the flotation mattress pad taken along lines 2-2 of Fig. 1;
  • Fig. 3 is a plan view of a portion of the mattress pad indicated in Figure 1 by circle 3 showing the quilting design thereon;
  • Fig. 4 is a perspective view similar to Fig. 1 but showing a mattress pad with a single inner bladder with retaining straps; and Fig. 5 is a perspective view of the underside of the mattress pad of Fig. 1.
  • a flotation mattress pad 8 is shown in an open position in Fig. 1.
  • a zipper 20 is used to removably affix a top of a mattress cover 14 to a side of the mattress cover 14.
  • Disposed within the mattress cover 14 are two double bladder assemblies 15, each bladder assembly 15 including an outer bladder 12 which surrounds an inner bladder 10 which contains a valve 16 therein, which valve is used to fill the inner bladder 10 with a fluid such as water.
  • the flotation mattress pad in Fig. 1 is for a wider bed, such as a standard size double mattress bed, a queen size mattress bed or a king size mattress bed, and appropriately contains two half-width, full length bladder assemblies 15. Alternatively, rather than using the two half-width outer bladders, a single full width outer bladder may be employed (not shown) .
  • the bladder would have two circular openings 17 in its top side positioned to permit access to the valve 16 in each inner bladder 10.
  • Utilization of two half-width inner bladders 10 and outer bladders 12 reduces the transmission of waves caused by one user of the flotation mattress pad 8 to a second user laying beside the first.
  • the mattress pad 8 is preferably about 5 centimetres (2 inches) thick; however, it may be as thin as 2.5 centimetres (1 inch) or as thick as 10 centimetres (4 inches) .
  • Fig. 2 is a sectional view of the flotation mattress pad 8 taken along lines 2-2 of Fig. 1.
  • the mattress cover 14 surrounds the outer bladder 12 which itself surrounds the inner bladder 10 which holds the fluid 44 therein.
  • the outer bladder 12 may be made of a thinner material than the inner bladder 14.
  • the outer bladder could be made of 10 mil vinyl and the inner bladder made of 20 mil vinyl.
  • the upper side 40 of the mattress cover 14 is composed of a mattress ticking 26 which is peripherally edged by a hem 18 which binds the outside edges of the layers of the mattress ticking 26 to each other as well as securing one side of the zipper 20 to the mattress ticking 26.
  • the mattress ticking 26 itself is composed of a top polyester woven cloth 28, which is above a non-woven polyester filling 30, which is above a polyurethane foam layer 32, which is above a thermal barrier 34, which is above a bottom polyester cloth 37, all of which are quilted together.
  • the thermal barrier layer 34 consists of a thin plastic film 35, reflective on both sides, which is attached to one side of a felted sheet 36.
  • the other side of the zipper 20 is secured to an upper edge of a side surface 22 of the mattress cover 14.
  • An additional hem 19 secures a lower edge of the side surface 22 of the mattress cover 14 to the bottom 24 of the mattress cover 14.
  • cover 14 could be made out of lambswool or conventional mattress ticking. Also, cover 14 could be made reversible, with upper side 40 having lambswool on one side and normal mattress ticking on the other side. With a full zipper 20 around the periphery of cover 14, mattress cover 14 could be turned inside out to make the upper surface either lambswool or mattress ticking.
  • Optional attaching devices such as flaps 21 may be provided at the corners and along the sides of cover 14. Flaps 21 are provided with grommets 23 for attaching light rope or straps 25 to mattress pad 8 for tying down the mattress pad where it is used in a mobile location such as in a truck, a recreation vehicle or a boat.
  • straps 25 could be attached directly to cover 14 or to flaps 21 by being sewn in place, and such straps could be provided with hook and loop type releasable fasteners on the ends of the straps so that they could surround an anchoring device or even another conventional mattress located under mattress pad 8.
  • the flotation mattress pad may be marginally shortened and narrowed in order to provide a space between the peripheral edges of the bed mattress and the peripheral edges of the mattress pad when viewed in plan.
  • Fig.3 is an enlarged plan view of the mattress ticking 26 showing the top side 40 of the mattress cover 14, having a decorative quilting stitching 38 which holds all the layers together.
  • a mattress pad 50 is shown which would be suitable for each one of a set of twin beds, or a single bed.
  • a single bladder assembly 15 shown in chain dotted lines in Fig. 4 would be used inside an appropriately sized cover 14.
  • a flotation mattress pad for a single bed is sufficiently light that a child might be able to pull it off the bed.
  • the mattress cover may be provided with two outer safety straps 52 attached to the underside or bottom 24 of cover 14. One strap would encircle each end of a conventional bed mattress to secure mattress pad 50 in place.
  • the two safety straps are about 7.5 centimetres (3 inches) wide, are formed of elasticized fabric, and are sewn between opposed bottom hems 19 of mattress cover 14.
  • three non-stretch inner straps 54 span from opposite bottom side hems 19 of mattress cover 14, across the top of the bladder assembly 15 to hold bladder assembly 15 inside mattress cover 14.
  • Straps 54 are about 7 to 10 centimetres in width and are made of the same material as side surfaces 22, which is a felted synthetic material flame treated to increase tear strength, but yet remain breathable. However, straps 54 could be made of any suitable webbing or elasticized material, if desired. Straps 52, 54 are optional, and usually are not required at all on the larger mattress pads containing two bladder assemblies 15. However, straps 52, 54 could be employed in the embodiments shown in Figures 1 to 3 if desired.
  • the inner bladders may be filled with an antifreeze solution such as ethylene glycol or propylene glycol to prevent freezing.

Abstract

L'invention concerne un matelas relativement mince destiné à un lit, comprenant trois parties distinctes: une vessie interne (10), un vessie externe (12) et un enveloppe de protection du matelas (14). Ladite vessie interne est formée d'une face supérieure et d'une face inférieure rectangulaires qui sont soudées le long des bords. La partie supérieure comporte une valve (16). La vessie externe représente une protection véritablement efficace pour la vessie interne. Cette vessie externe entoure la vessie interne et elle est étanche aux fluides excepté au niveau d'une ouverture circulaire (17) qui permet d'accéder à la valve située sur la partie supérieure de la vessie interne. Elle est fabriquée suivant le même procédé que la vessie interne, qu'elle enferme de manière permanente. L'enveloppe de protection du matelas présente une surface supérieure (40) réalisée en coutil piqué (26). Ledit coutil comprend une couche de protection thermique (34). L'enveloppe de protection du matelas présente un fond (24) et des côtés (22) réalisés dans un tissu tissé relativement léger. Cette enveloppe de protection entoure complètement la vessie. Une fermeture éclair allongée (20) située le long du bord de la surface supérieure permet d'introduire les vessies et d'accéder à la valve qu'on utilise pour le remplissage.
