The waterbed 1 includes a mattress 2 , which is filled with water or another medium and heated. This mattress 2 is in a picture with a frame 3 on a mattress carrier 6 added. The frame 3 is up here on a head side 4 and a foot side 5 of the waterbed 1 or the mattress 2 shown. The mattress carrier 6 is on a pedestal 7 arranged, with unspecified supports 8th of which only one is shown schematically, stiffened and reinforced. On a top 2a the mattress 2 is a schematically represented person 9 , The top 2a the mattress 2 is elastic and adapts to the body shape of the person 9 at.

In the area of the foot side 5 is the mattress 2 with a passage 20 formed, which is circular here and is substantially perpendicular from a bottom 2 B to the top 2a the mattress 2 extends through the same. The implementation 20 is with a wraparound wall 22 opposite the water-filled interior 2c the mattress 2 sealed. The wall 22 For example, it can be made of the same mattress material 2 be prepared and is at least in the direction of movement 26 compressible or flexible by means of suitable folds. At the top 2a the mattress 2 is the implementation with a movement element 21 closed, with the moving element 21 here is circular and a section of the material of the top 2a the mattress 2 forms. On the bottom 2 B can carry out 20 completely open in diameter or except for a drive opening 31 (please refer 7 ) to be introverted.

The movement element 21 is via a connection 24 with one end of a drive element 23 connected pivotably about an axis. The connection 24 can be a joint or a flexible connection. The drive element 23 For example, it may be a rod, a rope or a strip of cloth or the like. The drive element 23 extends through the implementation 20 through an opening 6a in the mattress carrier 6 in a room inside the pedestal 7 in the area of the foot side 5 of the waterbed 1 , At the end of the drive element located in this room 23 Here is a coupling element 25 provided, which is formed like a loop.

In this room is a drive device 10 arranged. The drive device 10 includes an engine 11 with a motor axis 16 , a clutch connected to its output 12 and a connected gearbox 13 , Furthermore, the drive device 10 a bracket 17 and a controller 18 on.

The gear 13 here has an output element 14 on, which as an eccentric with an eccentric axis 14 around the motor axis 16 rotates. The output element 14 is with the coupling element 25 of the drive element 23 connected. The output element 14 For example, it may be a bolt or hook that fits into the loop-like coupling element 25 is plugged in.

The drive device 10 with engine 11 , Clutch 12 , Transmission 13 and control device 18 is on the bracket 17 attached and with this as a unit einbaubar. Here is the bracket on the mattress carrier 6 attached. Of course, other locations may be possible, for example on one of the supports 8th or on the pedestal 7 ,

For the function of the drive device 10 this is done by means of an operating device 19 , which are here on the frame at the top 4 is arranged, actuated. This will be explained in more detail below.

The switched-on drive device 10 generated by means of the engine 17 a rotational movement which via the clutch 12 to the gearbox 13 is transmitted. The coupling 12 is here as a safety component in the form of an overload clutch, z. B. slip clutch formed. The gear 13 converts the rotary motion into a reciprocating motion by the output element 14 on a circular path as an eccentric around the motor axis 16 rotates and thereby over the coupling element 25 the drive element 23 placed in a movement corresponding to that of a crank chain. The revolving output element 14 forms the crank. By the connection of the drive element 23 via the connection to the movement element 21 becomes a reciprocating motion, z. B. with a stroke of about 5 cm, the moving element 21 in a direction of movement 26 essentially perpendicular to the top 2a the mattress 2 generated. The movement element 21 may have an elasticity, that of the top 2a the mattress 2 is equal to or less.

The movement of the movement element thus generated 21 gets on the medium in the interior 2c the mattress 2 transmitted, whereby this gets into a vibration with wave motion. The waves are planted within the medium from the foot side 5 away to the head, what's on the top 2a person 9 as a massage can feel. The vibration or wave generation by the drive device 10 can be adjusted by an adjustable speed of the motor 11 be changed in a predetermined frame. This is related to 8th described in more detail.

The drive element 23 transmits only tensile forces on the movement element as rope or fabric strip 21 and pull it down towards the pedestal 7 , The moving element is after reaching a bottom dead center of the crank or the output element 14 due to the spring action of the mattress 2 , the Wall 22 the implementation 20 pushed up again. The walls of the mattress 2 be through the interior 2c located incompressible medium during the vibrations deflected accordingly.

In 2 is a plan view of a first embodiment of a mattress according to the invention 2 shown.

It's just the mattress 2 with her top 2a shown, their structure corresponds 1 , head 4 and foot side 5 are each given, with the length of the mattress 2 by the distance between the head side 4 and foot side 5 is fixed. In the area of the foot side 5 are in this example three movement elements 21 across the width of the mattress 2 distributed at right angles to the length. The two outside moving elements 21 are allow by suitable distance to the middle movement element 21 a shelf for the legs of the person 9 , All movement elements 21 are with connections 24 (dashed), where (not visible) in each case a drive element 23 is articulated, and each form an upper closure of a respective associated implementation 20 (please refer 1 ). The bushings 20 are as explained above in the mattress 2 built-in. The diameter of a movement element 21 may be 15 to 20 cm, for example.

In this case, every movement element 21 a drive device 10 assigned. It is possible that these drive devices 10 synchronously or individually independently for movement generation can be used.

For a particularly even across the width of the mattress 2 distributed movement initiation can, according to a second embodiment, the in 3 with representation of the top of the mattress 2 is shown, a movement section 27 in the top 2a the mattress 2 be introduced, which is the movement elements 21 combines. This movement section 27 can also be in the material of the top 2a molded or formed on the inside.

4 shows a plan view of a third embodiment of the invention mattress 2 , in which in the foot area a movement strip 28 is applied, on both sides, each with a connection 24 provided and is drivable about it. The movement strip 28 here forms a planar, rectangular movement element and can special stiffeners in its longitudinal direction across the width of the mattress 2 exhibit. In 5 is a molding or insertion of the moving strip 28 in a bag 29 the mattress 2 in a partial sectional view of the third embodiment according to 4 shown, with the bag 29 in the top 2a is located and across the width of the mattress 2 extends.

Alternatively, the bag may be 29 also in a reference 30 are located. This is as a variant in a partial sectional view 5 shown. The reference 30 can be done later from the foot side 5 over the mattress 2 to be pulled. As a result, this is for the movement initiation of a drive means to be assigned 10 retrofitted.

In the embodiments according to 4 to 6 It is advantageous if an area of the top 2a below the motion inducing element 28 has a higher elasticity. Because this is in the area of the foot 5 the mattress 2 In the case, this does not cause the person's unpleasant feelings of discomfort 9 out.

In 7 is clearly visible that the bottom 2 B the mattress 2 the implementation 20 except for one opening 31 closes. The drive element 23 extends through this opening 31 and hangs on the bottom 2 B out. In this embodiment, the transmission 13 designed such that the output element as a hook element 14a is formed, which already a reciprocating linear motion in the direction of movement 26 when the engine is switched on 11 the drive device 10 performs. Due to the hook-shaped shape of the hook element 14a is a threading of the same in the loop-shaped coupling element 25 especially light and easy when the drive device 10 , z. B. as a complete unit, under the mattress support 6 (not shown here, but related to 1 easy to imagine) is installed.

Finally shows 8th an exemplary block diagram of the drive device 10 the waterbed according to the invention 1 ,

Here is the controller 18 for the mattress 2 or the waterbed 1 with the mattress 2 to 2 with three drive devices 10 shown. Of course it can be less or more. The control device 18 is with a connection 18a to an electrical energy source, eg. As a power grid or a battery supply connected. In addition, the controller is available 18 with the operating device 19 in connection. This connection can be wired or wireless, z. As radio or infrared, his. Here are the drive devices 10 synchronized, ie all motors run in the same direction of rotation and angle of rotation, so that the coupled motion elements 21 perform equal up and down movements, or are in phase. The control device 18 can z. B. electromechanical and / or semiconductor switching elements, wherein the motors 11 Can be DC, AC or AC motors. It is advantageous if their supply voltage is a safety extra-low voltage in order to minimize dangers.

The actuating device 19 has a switch-on element in this example 19a , a switch-off element 19b , a first control switching element 19c and a second control switching element 19d on. With the activation element 19a become the drive devices 10 switched on, with the switch-off element 19b switched off. The first control switching element 19c serves to increase the oscillation frequency of the movement elements 21 ie, to increase the speed of the motors, and the second control 19d to reduce the oscillation frequency. Of course, other versions with z. B. rotary switches and rotary actuators possible.

The embodiment described above does not limit the invention. It is modifiable within the scope of the appended claims.

It is conceivable, for example, that with two or more movement elements 21 only one drive device 10 is provided, wherein the drive elements 23 then to a common output element 14 , For example, a continuous rod, are coupled. Even a continuous, cranked "crankshaft" is conceivable.

The stroke of the hook element 14a can by means of an adjustable transmission 13 be adjustable.

The movement elements 21 may have other shapes instead of circular areas.

The reference 30 to 6 can be a relatively rigid movement strip 28 have, with a padding over the bag 29 is arranged.

The movement strip 28 to 4 can be made retrofittable as a rigid element, with a corresponding padding is useful here as well.

The drive element 23 can also be done within the implementation 20 ends, with a coupling rod or a coupling band between the output element 14 and the coupling element 25 is provided that from the bottom 2c in the implementation 20 introduced and with the coupling element 25 is coupled.

It is also conceivable that the drive element 23 as a separate part in the connection 24 can be used.

Furthermore, it may be possible for two or more drive devices 10 these are not only synchronous but also individually, in groups or separately controllable to the oscillation frequency of the movement elements 21 to influence individually.
