Flexible air cushion unit and assembly structure

Abstract

The present invention provides an air cushion unit that can be assembled into any shape and dimension, and more particularly to an innovative one which is prefabricated with interconnected air rings, air pipes and air chambers along with close-packed air columns and air nozzles, allowing to adjust flexibly the pressure value. So, it can be widely applied to meet different sitting or lying demands under various stress states.

Description

BACKGROUND OF INVENTION[0001](1) Field of the Invention[0002]The present invention relates generally to an air cushion unit, and more particularly to an innovative one which is prefabricated with interconnected air chambers, close-packed air columns and nozzles, allowing to adjust flexibly the pressure value for meeting the customer demands.[0003](2) Description of the Prior Art[0004]People often place pads or cushions on the chairs or beds for comfortable sitting or lying.[0005]Such pads or cushions are generally made of foamed materials such as cotton cloth or sponge, or sealed liquid materials. However, the following shortcomings are observed during actual applications:[0006]Firstly, any cushion presents a given flexibility no matter it is made of whichever materials, so it is impossible to change the flexibility for most comfortable sitting or lying at one's own discretion or preference.[0007]Secondly, any cushion is designed for specific requirements, namely, the flexibility ma...

AI Technical Summary

Benefits of technology

[0010]Thus, to overcome the aforementioned problems of the prior art, the inventor has provided the present invention of practicability. The major objective of the present invention is to assemble an air cushion unit composed of air pipe, air ring and air chamber along with close-packed air columns; moreover, with the support of interconnected independent air chambers, the air cushions permit to generate consistent stress state, thus achieving optimum sitting or lying equilibrium and comfort.

[0011]Another objective of the present invention is to design interconnected independent air chambers of air cushion units along with air nozzles, enabling the users to set flexibly the stress value for meeting their own sifting or lying requirements.

[0013]Another objective of the present invention is to arrange the tapered mouths at both sides of air columns, so that air cushion units could be compactly assembled via screws.

Problems solved by technology

Firstly, any cushion presents a given flexibility no matter it is made of whichever materials, so it is impossible to change the flexibility for most comfortable sitting or lying at one's own discretion or preference.

Secondly, any cushion is designed for specific requirements, namely, the flexibility may be pursued with compromise of air permeability, or air permeability may be pursued with compromise of comfort.

Thirdly, some cushions may lose original comfortable function due to gradual hardening of soft materials.

Fourthly, the cushions made of any material will be subject to the distortion or deformation of the stress surface, making it difficult to achieve optimum sitting or lying comfort.
