Definitions

  • the present invention is directed to a waterbed and more specifically to a waterbed which provides a cushion about its perimeter which serves to maintain the mattress height at the perimeter and, to some extent, maintain the perimeter shape.
  • Means are provided to give additional rigidity to the cushioned side walls to prevent their flexing upon the effect of water pressure from the water bag within, the additional means being in the form of a liner for the water bag itself which liner also envelopes the cushions and is secured to itself so as to form a sling which constrains the outward movement of the cushions.
  • a relatively high pressure "air frame” has been employed, the pressure in the "air frame” being sufficiently high to withstand the weight of the occupant as he leaves or enters the waterbed.
  • the "air frame” does, of course, provide substantial relative comfort compared with the rigid wood frame.
  • a liner was provided originally in the form of an impervious vinyl open topped bag secured to the wooden frame so as to contain any such leakage. Later, the liner took the form of a second water bag but with a major portion of the top open so as to permit access to the valve for filling the inside bag or bags.
  • the resilient peripheral support structure is retained in position by the waterbed liner, the liner structure itself forming slings along each of the rectilinear sides of the water bag with the cushion being removable either by opening the slings or by passing the cushion through openings at the ends of the slings.
  • the water bag cooperates with the slings to maintain the rectilinear condition of the peripheral supports by restricting their movement.
  • FIGURE 1 a perspective view of a waterbed showing the water bag encased in resilient peripheral supports retained by slings formed in the liner.
  • FIGURE 2 is a perspective view of the waterbed, as shown in FIGURE 1, but with the water bag removed.
  • FIGURE 3 is a sectional view along the lines 3-3 of FIGURE 2 showing particularly the position of the slings when there is no water bag in the waterbed.
  • FIGURE 4 is a view taken along the lines 4-4 of FIGURE 1 and is similar to FIGURE 3 but showing the position of the slings when the water bag is in place.
  • FIGURE 5 is a detailed view taken along the lines 5-5 of FIGURE 3 showing one form of attachment of the upper portion of the sling to the bottom of the liner.
  • FIGURE 6 is a view similar to FIGURE 5 but showing an alternate form of attachment.
  • FIGURE 7 is a plan view showing the position of the resilient peripheral supports and their attachment to each other but with the waterbed liner and slings not being shown for clarity.
  • FIGURES 8 and 9 are perspective views respectively of side and end resilient peripheral cushions showing a preferred means of attachment.
  • FIGURE 10 is a view similar to FIGURE 4 but showing a desirable addition in the form of a removable mattress ticking about the entire waterbed so that it has the outward appearance of an innerspring mattress.
  • FIGURE 11 is a perspective view, similar to FIGURE 2 but showing alternative sling opening means.
  • FIGURE 12 is a sectional view taken along the lines 12-12 of FIGURE 11.
  • FIGURE 1 a waterbed 11 which includes a water bag 13 surrounded by a liner 15.
  • the liner 15 not only includes a bottom 17 (not shown in FIGURE 1 but seen in FIGURES 3 and 4) together with generally upright rectilinear sides 19 and ends 21. Further extensions of the upright sides 19 form inwardly extending portions 23 and 25 while continuations of the ends 21 form inward extensions 27 and 29.
  • the extensions 23 and 25 cooperate with the sides 19 and the bottom 17 to form slings.
  • the inward extensions 27 and 29 cooperate with the ends 21 and the bottom 17 to form two additional slings.
  • the manner of securing the extensions to the bottom 17 is by means of a hook and loop fastener wherein one element, for instance the loop portion, 31, is permanently secured to the bottom 17 in any convenient manner such as by heat sealing or adhesive, for example.
  • the hook portion 33 is secured to the end edges of the inwardly extending members 23, 25, 27 and 29 as typically shown in FIGURE 5.
  • the slings formed in part by the inwardly extending members 23 and 25 serve to retain resilient side peripheral supports 35 and 37.
  • the slings formed in part by the inwardly extending members 27 and 29 serve to retain end peripheral supports 39 and 41.
  • the resilient peripheral supports 35, 37, 39 and 41 may, as shown, be in the form of rectilinear air bags or cushions each having a valve 43 for the admission of air from any desirable means such as from the exhaust of a normal home vacuum cleaner.
  • the resilient peripheral supports may be in the form of foam rubber or the like or even the combination of air bag and foam rubber.
  • the side cushions 35 and 37 each incorporate fastening means 45 ne ar the ends thereof on their inner surface.
  • Such fastening means may take the form of the loop portion of a loop and hook fastener.
  • the corresponding hook portion 47 is secured at the ends of the end portions 39 and 41.
  • the hook and loop portions cooperate to secure each of the cushions 35, 37, 39 and 41 in a generally rectangular array as shown in FIGURE 7.
  • the liner 15 is placed on a flat surface onto which the bed is to be located.
  • the flat surface may be a rigid platform such as of plywood or the like, or it may be a boxspring of a normal bed.
  • the resilient cushions are placed in position and if the cushions are in the form of air bags it is preferable that they be inflated prior to positioning within the liner 15, although this is not essential.
  • the position of the cushions in a liner of the type shown in FIGURES 2 and 5, is accomplished by merely releasing the hook and loop fasteners, connecting the extensions 23, 25, 27 and 29 to the bottom 17, placing the cushions in the pocket of the slings formed by such extensions and bottom.
  • the fasteners are then reconnected such that the extensions 23, 25, 27 and 29 are drawn over a free space 49 between each cushion and the extension itself as shown typically in FIGURE 3, with respect to the cushion 35 and the extension 23.
  • Such placement of the cushions should also include the connection of the hook and loop fasteners 45 and 47 on the cushions themselves so as to assure that they take the general position as shown in FIGURE 7.
  • the empty water bag 13 is placed on the bottom 17 within the confines of the cushions as well as the inward extensions 23, 25, 27 and 29.
  • the water bag 13 is then filled with water until it takes on the condition, as shown in FIGURES 1 and 4 and the extensions 23, 25, 27 and 29 take the position as shown in FIGURE 4. It will be noted that upon filling the water bag 13 with water the weight of the water forces the extensions to be tightened by increasing their linear path or extent from that as shown in FIGURE 3 to the longer and more tortsious path as shown in FIGURE 4.
  • each extension may originally be drawn taut, as shown in FIGURE 3, but need not be so.
  • each extension may form a curve from its point of contact with the cushion (e.g. cushion 35) to the bottom 17 so long as a free space 49 is formed into which the extension may be forced by the filled water bag.
  • the linear path or extent of the extension from the top of cushion to the point of attachment to the bottom 17 is elongated when the water bag is filled. This elongation serves to tighten the extensions 23, 25, 27 and 29 and thus tends to roll the cushions inwardly.
  • the extensions could be permanently secured to the bottom 17 such as by a heat seal 51, as shown in FIGURE 6.
  • the sling may not be opened at the ends of the extensions 23, 25, 27 and 29 as is the case with the hook and loop connection but rather the cushions may be individually inserted at the corner separations 53 formed by the individual extensions 23, 25, 27 and 29 as shown in FIGURES 1 and 2.
  • the cushions are not absolutely rigid but rather will bend slightly and likewise the material of the liner 15 is sufficiently pliable that it may be pushed out of the way at the opening 53 to permit passage of the cushion.
  • extension 29 may be pushed downward and the adjacent portion of extension 23 raised slighly so as to increase the opening 53 to permit passage of the cushion.
  • insertion or removal of a cushion in this manner may even be accomplished with the water bag 13 filled with water. It will, of course, be necessary to somewhat relieve the pressure of the water at the edge of the bag adjacent the cushion to be inserted or removed.
  • the waterbed 11 is shown with totally enclosing ticking, of fabric or other mattress material.
  • the ticking may be quilted as on more modern mattresses or the standard ticking of the more institutional mattresses available today. Particularly the ticking need not be waterproof and preferably is capable of permeating air.
  • the ticking includes a bottom 55 and an upstanding wall portion 57 which completely surrounds the upright sides of the waterbed 11.
  • the bottom 55 and side 57 are sewn together at a bead 59 extending about the entire periphery of the bottom 55.
  • a top 61 is removably secure such as by means of a zipper 63.
  • the top 61 may be removed or at least opened so as to service the waterbed within.
  • the inward extensions 23 ⁇ , 25 ⁇ , 27 ⁇ and 29 ⁇ each include an openable closure 65, such as a zipper.
  • the closures 65 are located adjacent the upright sides 19 and ends 21 and positioned to be accessible at the top of the cushions.
  • the closure 65 may be used to insert or remove the individual peripheral cushion.
