Abstract
An automatic inflatable cushion includes a cushion body, at least two airbags installed in the cushion body and capable of adjusting height and saturation independently, and an elastic member having fine pores filled in each airbag, and a manual switch valve installed on an outer surface of each airbag, so that when the manual switch valve is pressed towards the inside from both sides, the elastic member in the airbag is expanded and inflated naturally to improve the convenience of adjusting the height and saturation of the cushion.
Description
- The present invention relates to cushions such as pillows, seat cushions, backrests etc provided for users to lay or sit on, in particular to an automatic inflatable cushion whose height, saturation, and comfortability can be adjusted simply and easily.
- Cushions including pillows, seat cushions and backrests available in the market are provided for us to lay, sit or lean on. For example, an appropriate pillow usually has the effects of improving our sleeping quality significantly, overcoming the problem of cervical pains effectively, and providing good prevention and treatment to the cervical pains. A major factor for determining whether or not a pillow is appropriate depends on the height and softness of the pillow, and our living habits are different from one another, so that the definition of the appropriate height and softness of the pillow varies. However, most pillows available in the market are filled pillows, and the height and softness of such pillows are fixed and cannot be adjusted, so that it is not easy for users to select the pillows with appropriate height and softness of themselves. Pillows with inappropriate height and softness not just cause difficulty to cure cervical fatigue and pain only, but also affect sleeping quality and physical health. Similarly, the conventional filled seat cushions and backrests have the drawback of unable to adjust the height and softness flexibly or meet the requirement of each individual's need.
- In view of the aforementioned common drawback of the conventional cushion including pillow, seat cushion, backrest, etc, an automatic inflatable was introduced into the market, and such cushion comprises an airbag installed in the cushion, an elastic member filled in the airbag and automatically expanded or compressed by external forces, and a manual air valve installed on a surface of the airbag and having a single press button installed at the top of the manual air valve. When a user presses the press button, the airbag and the elastic member in the cushion are expanded, so that the air in the airbag is squeezed out from the manual air valve. Now, if the user releases the press button, the air in the airbag will be stopped from discharging out from the manual air valve, and the cushion will remain at a compressed status with the airbag. If the user presses the press button again, the elastic member will be expanded automatically to pop up the uncompressed airbag and cushion, so that the outside air is sucked into the airbag from the manual air valve naturally. Now, if the user releases the press button, the air in the airbag will be stopped from discharging out from the manual air valve, and the cushion will remain at an expanded status with the airbag.
- However, the drawback of such inflatable cushion resides on that the press button is pressed by a user in a direction from the top of the manual air valve towards the airbag, so that when the user presses the cushion, the action force pressing on the press button is also applied to the airbag to deform the cushion, distribute the user while adjusting the height and softness of the cushion, and cause inconvenience to shape the cushion.
- In view of the aforementioned problems and drawbacks of the prior art, the inventor based on years of experience in the related industry to conduct extensive researches and experiments, and finally designed and develop an automatic inflatable cushion in accordance with the present invention to overcome the problems and drawbacks of the prior art.
- Therefore, it is a primary objective of the present invention to provide an automatic inflatable cushion, particularly the automatic inflatable cushion whose height and softness can be adjusted simply and easily to overcome the drawbacks of the prior art including the deformation of the cushion caused by pressing the press button from the top of the manual air valve towards the airbag, the interference to users to adjust the height and softness of the cushion, and the inconvenience of shaping the cushion.
- To achieve the aforementioned and other objectives, the present invention provides an automatic inflatable cushion, comprising: a cushion body; at least two airbags, installed in the cushion and capable of adjusting the height and saturation; an elastic member, having fine pores filled in the airbag; and a manual switch valve, installed on a surface of the airbag, and including a valve body interconnecting the interior of the airbag to outside air, and two press buttons symmetrically installed on both side of the valve body and provided for selectively opening and shutting the valve body.
- In the aforementioned structure, each press button may be pressed from both sides of the valve body such that the press buttons become closer to each other in order to reduce the height of the cushion body and allow the interior of the airbag to be interconnected to outside air. Now, if the user presses the cushion body again, the airbag and its fine pores and elastic member are compressed to discharge air from the valve body. After the cushion body is compressed to an appropriate height, the user may release each press button, and allow the press buttons to restore their original positions automatically to close the valve body, so that the interior of the airbag is isolated from the outside air. Such arrangement can maintain the height and softness of the cushion body as the airbag shrinks.
- If it is necessary to increase the height of the cushion body, the user may press the press buttons again, so that the interior of the airbag is interconnected to the outside air. Since the two press buttons are disposed on both sides of the valve body respectively, the cushion body is not pressed when the force is applied to the press buttons, so that the airbag containing the elastic member with the fine pores is expanded naturally, and air enters from the valve body. After the airbag is inflated to an appropriate height, each press button is released, so that the cushion body can increase the saturation and maintain the height with the airbag.
- In an embodiment, the valve body includes a valve chamber formed therein and interconnected to the interior of the airbag, a valve port formed separately on both sides of the valve body and interconnected to the valve chamber, a valve door movably installed in the valve port, and spring installed between the valve doors and provided for driving the valve door to open or shut the valve port, and each press button is installed on the respective valve door and exposed from the respective valve body through the respective valve port, and provided for being pressed from both sides of the valve body towards the center of the valve body to open the valve port.
- In an embodiment, the valve body includes a flared ring disposed at the bottom of the valve body and capable of performing a high frequency wave sealing with the surface of the airbag surface, so that the ring can be soldered onto the valve body by high frequency wave sealing.
- In an embodiment, the cushion body is a pillow, a seat cushion or a backrest.
- In an embodiment, the two airbags are partially stacked, and the stacked position of the airbags has a smaller thickness.
- In an embodiment, the cushion body has a first arc surface, and the airbag has a second arc surface corresponsive to the first arc surface.
- Compared with the prior art, the present invention includes at least two two airbags installed in the cushion body for independently adjusting height and saturation, and an elastic member with fine pores filled in the airbag, and a manual switch valve installed on a surface of the airbag. When use, the cushion body is pressed from both sides of the manual switch valve towards the center, so as to prevent the pressing force from being applied onto the airbag or affecting the natural expansion or inflation of the elastic member, and improve the convenience of adjusting the height and saturation and comfortability of the cushion. The present invention can overcome the problem of causing a deformation of the cushion body when a force applied to the press button is exerted onto the airbag.

Seal the periphery of the fabric by the high frequency wave sealing method to form the
airbag 20, and arrange themanual switch valve 40 at an edge of theairbag 20, and reserve a side pocket when sealing the periphery of theairbag 20. - 3. Stuff the
elastic member 30 into theairbag 20 from the side pocket, and then sealing the side pocket of theairbag 20 by the high frequency wave sealing method, and theelastic member 30 stuffed in theairbag 20 always maintains an upwardly or downwardly expanded elastic force. - With the aforementioned structure, each
press button 421 may be pressed from both sides of the valve body 41 (as shown inFIG. 6 ) to overcome the elastic force of thespring 50 in order to reduce the height of thecushion body 100, so that thevalve doors 461 become closer to each other with thepress button 421 to open thevalve ports 45 on both sides of thevalve body 41, and the interior of theairbag 20 is interconnected to outside air through the throughhole 21, theair inlet 44, thevalve chamber 43 and thevalve port 45. Now, if anyairbag 20 in thecushion body 100 is pressed again, theairbag 20 and its fine pores andelastic member 30 will be compressed, and the air in theairbag 20 will be released from thevalve ports 45 on both sides of thevalve body 41 to the outside. After thecushion body 100 is compressed to an appropriate height, eachpress button 421 is released (as shown inFIG. 5 ) to drive thespring 50 to restore thevalve doors 461 and thepress button 421 to their original positions, and thevalve doors 461 shut thevalve ports 45 on both sides of thevalve body 41 respectively, so that the interior of theairbag 20 is isolated from the outside air to form an aright status. Therefore the height and softness of thecushion body 100 are maintained as theairbag 20 shrinks. - If a user wants to increase the height of the
cushion body 100, the user may press thepress buttons 421 again to open thevalve ports 45 on both sides of thevalve body 41, so that the interior of theairbag 20 is interconnected to outside air through thevalve ports 45. Since the twopress buttons 421 are installed on both sides of thevalve body 41 respectively, therefore the force applied to thepress buttons 421 is not exerted onto thecushion body 100, and theelastic member 30 having the fine pores in theairbag 20 can be expanded naturally, and air enters from thevalve ports 45 of thevalve body 41. After theairbag 20 is inflated to an appropriate height, eachpress button 421 is release to shut thevalve port 45, so that thecushion body 100 can improve the saturation and maintain the height with theairbag 20. - It is noteworthy that the
elastic member 30 is made of a breathable material such as particles or filaments filled into a fabric or bag, so that when air flows into or out of theairbag 20, the fabric or bag can block the impact force of the air current exerted onto the particles or filaments and prevent them from sticking onto thevalve door 461 and prevent an air leakage of thevalve door 461. - With reference to
FIGS. 7 to 9 for another preferred embodiment, two symmetrical axial connectingportions 48 are disposed on an inner wall of thevalve chamber 43, and anaxial sleeve 463 is formed at an end of thevalve door 462 and pivotally coupled to the axial connectingportion 48, so that an end of thevalve door 462 is pivotally coupled to the inner wall of thevalve chamber 43, and eachpress button 422 is installed on therespective valve door 462, and exposed from both sides of thevalve body 41 through thevalve port 45. InFIG. 10 , when the user presses thepress buttons 422 on both sides of thevalve body 41, thevalve doors 462 are driven by thepress buttons 422 to rotate to a tilted status to open thevalve port 45. The remaining components and implementation method are the same as the foregoing embodiments, and thus will not be repeated. - In
FIG. 7 , anelastic ring 12 may be installed at the periphery of theopening 11 for sheathing the flaredring 47 of themanual switch valve 40 and preventing the exposedmanual switch valve 40 from being separated from theopening 11 due to the movement of thecushion body 100. - With reference to
FIG. 11 for another feasible embodiment, thecushion body cushion body 102 is a backrest, thecushion body 102 may have afirst arc surface 13, and theairbag 20 may have asecond arc surface 22 corresponsive to thefirst arc surface 13, so that the seat cushion and the backrest may be used as an automobile seat cushion and backrest as well. - In summation, the present invention with the design of being pressed from both sides of the
manual switch valve 40 towards the interior to prevent the pressing force from being exerted onto theairbag 20, so that the natural inflation of theelastic member 30 will not be affected, and the convenience of adjusting the height and saturation and comfortability of the cushion can be improved. The invention can overcome the problem of the prior art having a deformation of the cushion body easily due to the forces applied to the conventional press button being exerted onto the airbag.
