Adjustable mattress

Abstract

An adjustable mattress includes a base layer, a lifting unit, an inflation unit, an elastic unit, and an air cushion layer. The lifting unit is disposed on the base layer. The elastic unit is spaced apart from the base layer and connected to the lifting unit. The air cushion layer is disposed on the elastic unit and connected to the inflation unit. The lifting unit controls the travel of the elastic unit, and the inflation unit controls the gas pressure of the air cushion layer.

Claims

1. An adjustable mattress, comprising: a base layer; a lifting unit disposed on the base layer; an inflation unit; an elastic unit spaced apart from the base layer and connected to the lifting unit; and an air cushion layer disposed on the elastic unit and connected to the inflation unit, wherein, The lifting unit controls the stroke of the elastic unit, and the inflation unit controls the gas pressure of the air cushion layer.

2. The adjustable mattress as claimed in claim 1 further includes a separating layer disposed between the air cushion layer and the elastic unit.

3. The adjustable mattress as claimed in claim 1 further includes a reinforcing unit that extends vertically and connects the elastic unit to the bottom layer, respectively.

4. The adjustable mattress as claimed in claim 1 further includes a filling layer disposed in the air cushion layer.

5. The adjustable mattress as claimed in claim 1 further includes at least one auxiliary rod extending and fixed to the elastic unit and the bottom layer.

6. The adjustable mattress as described in claim 1, wherein, The elastic unit includes a movable layer connected to the lifting unit, a fixed layer spaced between the movable layer, and an elastic layer disposed between the movable layer and the fixed layer. The lifting unit includes a manual actuator, a drive shaft connected to the manual actuator and extending horizontally, and two sliders respectively slidably sleeved on the drive shaft and respectively connected to the corresponding movable layer. The manual actuator can drive the drive shaft to displace the sliders relative to each other, thereby allowing the corresponding movable layer to move between a distant position and a nearby position relative to the bottom layer.

7. The adjustable mattress as described in claim 1, wherein, The air cushion layer includes an outer shell and a partition disposed within the outer shell, the outer shell and the partition defining two air chambers; the inflation unit includes two inflation pipes respectively communicating with the air chambers and two depressurization mechanisms respectively communicating with the inflation pipes.

8. The adjustable mattress as described in claim 7, wherein, The air cushion layer also includes a plurality of torsion plates respectively disposed in the air chambers and connected to the outer shell.

9. The adjustable mattress as described in claim 7, wherein, The inflation unit also includes two inflation motors disposed on the bottom layer and respectively connected to the inflation pipes, two pressure sensors respectively connected to the air chambers, and a controller electrically connected to the inflation motors and the pressure sensors.
