Abstract

A water bed comprises a pair of separate mattresses 20 whose firmness and temperature may adjusted independently of one another. Each mattress has a plurality of transverse portions 24 to reduce water vibration and turbulence within the mattress. A plurality of longitudinal air tubes 25 run through the transverse portions and communicate with an air bag. Pressurised air may be pumped into the air bag and tubes to allow the firmness of each mattress to be adjusted as desired. The mattresses are also separated by insulation which allows the water in them to be at different temperatures.

Description

WATER BED BACKGROUND OF TKE INVENTION 1. Field of the invention This invention relates to an improvcment for water bed and particularly to an improvement which can reduce water turbulence within the water bed The improved structure of the water bed according to the present invention is characterized by that it comprises two watered mattresses whose degree of resilliency and its temperature can be individually adjusted according to the different requirements of the couple sleeping on the bed 2. Description of the prior are Conventional watered usually employs high frequency fusion to form an air cushion flange around the water bed. The abrupt change of water pressure caused by external forces and the rapid and turbulent movement of water can ruptur: the flange at the fusion portion and results in water leakage. The resilliency of a conventional water bed is difficult to adjust and the bed body is not stable enouglL Moreover, the mattress (including those or without air bounding peripheries) itself is loosely constructed to form a configration of fiat circular flange not only disgusting in its appearance but also impending the danger of pesn sleeping on it to slip down accidentally.

Serious swinging or vibration caused by moving of a person sleeping on the bed often disturbs and awakens the other one. Further, the water contaaned in a conventional standard size watered is not isolated by any separator, consequently, there is no different in temperature and resilliency between two sides of the bed to meet with different requirements and habits of the couple sleeping on it, thus the couple must tolerate with each other A standard size watered has same level of temperature and softness that could become a problem when two people tying on it having different slceping habits and reiu cmcnts.

StLARY OF mE INVENTION In view of the above described disadvantages, it is therefore an object of the present invention to develop an improved structure of water bed in which plurality of transverse partitions are installed in the mattress which are able to effectively depress rapid longitudinal water flow from hcad to cnd of the mattress, and plurality of penetrated holes are provided for each partition for admitting small amout of water to seep through there between and alleviating the water pressure. In this way, an abrupt variation of water pressure caused by instantancously applying a heavy weight on the mattress can be effectively all@viated to a great extent. It is not only able to maintain very stable state of the mattress. but also can prevent the destruction of high frequency fused partitions on the mattress, but also can prevent the destruction of high frequency fished partitions on the marress by strong water hammer phenomenon It is another object of the present invention to provide for the actress a plurality of air tubes passing over above described transverse partitions. An air inlet is provided for an air bag installed at one side of the mattress for adjusting the resilliency of the mattress by injected air inside it and air tubes to make the mattress suitable for different weight and physical figures of individual users application. Therefore, the mattress of the water bed ray effectively support and contact every portion of the user's body when he is lying on the back or on the side thus the effect of complete support and profound rest of the user by lying on the water bed according to the present invention can be achieved from the viewpoint of human body engncering It is another object of the present invention by applying an unique means of Inside high frequency fusion to the above described plurality of transverse partitions to form a mattress weil stuffed and figured symmetrically.

It is yet another object of the present invention to providc two parts of water filled maaress combined in one piece to form a mattress unit for a standard size water bed By such arrangement, the couplet lying on the bed may individually adjust. the temperature and resilliency of their own sub-mattresses to fit their own requirements and weight without disturbing the other one tying besidc. Thus the aim of user's profound sleep an effect of protecting user's back bone will be obtained.

A fi=thcr object of the present invention is to provide, in case of water leakage caused by deterioration of high frequency fused partitions occurrs, a special protecting means which is the waterbed cover for the whole mattress to prevent the Icaking water from seeping out of the mattress and keep the water in the waterbed covcr so the floor of the bed room won't be contaminated. In addition, detachable rectangular shaped holes are provided both at the head and the end portions of the waterbed covcr for the convenience of filline the water in or replacing the individual sub-mattresses when it is necessary, the sub-mattress may be replaced individualy.

BRIEF DESCRIPTION OF mE DRAWINGS The invention, as well as its many advantage, may be further understood by the following detailed description and drawings in-which: Fig 1 is a perspective view of this invention; Fig 2 is a bottom view of this invention; Fig 3 is a perspective view of the water bed mattress; and Fig 4 is an exploded view of the water bed mattress.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to Figs. 1 and 2, the watered according to this invention includes a bed cover 101 two separate water bed mattresses 20 and a rectangular separator 21 made of foam or air bag which keeps the water bed mattresses 20 apart so that each water bed mattress 20 may have different softness and temperatres. The four lateral sides of the bed caver 10 may be padded with foams or air bags to make the mattress weil stuffed and shaped in symmetrical configuranom The two ends 40 of each water bed mattress may also be padded with a foam or air beg for same purpose. At the two ends of the top surface of the bed cover 10, there are two cut offopcnmgs 11 which enable the water bed mattress 20 be inserted, or removed there through Each water bed mattress 20 has a pair of water inlets 22 and an air inlet 23 located in the opening 11.

Referring to Figs. 3 and 4, the water bed mattress 20 includes a plural namber of transverse partitions 24. The four sides of each partition 24 are fixed on the inside surfaces of the water bed mattress 20 via high frequency fusion. It is principaUy able to facilitate the water bed mattress 20 to be well stuffed and form a synanctrical configuration around the peripherals of the water mattress 20. Especially the transversely arranged partitions 24 can effectively alleviate the water hammer phenomenon entailed by the abrupt variation of water pressure inside the water bed mattress 20. Each partition 24 has a plural number of opening 241 to facilitate water pressure leveling within the water bed mattress 20.
