DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1, 2, 3, and 4, a static equilibrium adjusting system according to the present invention comprises a bladder 10 and a regulation valve 20. A detailed description will be provided below, in which the bladder 10 has an internal space in which an elastic restoration device 11 is arranged to support an external pressing force 30.

The regulation valve 20 is connected to and in communication with the bladder 10 to provide an adjustable reverse-resisting force to resist an air pressure that is generated, in a direction toward the regulation valve 20, by the bladder 10 upon receiving the external pressing force 30 acting thereon.

In an embodiment, the elastic restoration device 11 comprises one of a foaming material, a foam, rubber, cotton-like material (such as cotton), chemical fiber cotton, for generating a rebounding force.

In an embodiment, the regulation valve 20 comprises a valve opening 21, a valve diaphragm 22, an elastic element 23, and a push member 24, wherein the valve opening 21 is arranged in an interior of the regulation valve 20 and in communication with the bladder 10; the valve diaphragm 22 is positionable in tight engagement with and seals and closes the valve opening 21; the elastic element 23 is in elastic contact engagement with the valve diaphragm 22; and the push member 24 is arranged at one side of the regulation valve 20 to push and press down the elastic element 23.

In an embodiment, the elastic element 23 is selected as a spring.

Referring to FIGS. 3 and 4, the external pressing force 30 presses downward the bladder 10 and the elastic restoration device 11, and in the instant embodiment, the external pressing force 30 is a human head pressing down the bladder 10 and the elastic restoration device 11. Through selection among bladders 10 having different sizes of internal space, and selection among of elastic restoration devices 11 having different densities and elastic properties, different negative pressure rebounding force may be generated, which, in combination with a balance force generated through regulation setting of the regulation valve 20, provides the bladder 10 with a supporting force of negative pressure difference, so as to achieve an effect of equilibrium among the external pressing force 30, the bladder 10, and the regulation valve 20, providing the bladder 10 with adjustability of supportability (namely softness/stiffness) and height, and the bladder 10, after adjustment of supportability and height, may automatically position and shape due to negative pressure effect.

When the external pressing force 30 presses down the bladder 10 and the elastic restoration device 11, such as a human head leaning on the bladder 10, the valve opening 21 generates an air pressure pushing open the valve diaphragm 22 to allow a portion of air to release out of the regulation valve 20 through the through opening formed in the regulation valve 20, and then, the elastic element 23 and the valve diaphragm 22 elastically seal and close the valve opening 21 to provide an opposite, corresponding reverse-resisting force to resist the air pressure that the bladder 10 generates, upon receiving the external pressing force 30, in a direction toward the regulation valve 20, to thereby achieve an effect of equilibrium support of the bladder 10.

Referring to FIG. 2, in an embodiment, the bladder 10 is connected to and in communication with a self-charging valve 40. The self-charging valve 40 comprises a plurality of apertures 41, and an airtight sealing element 42 is arranged in the self-charging valve 40 and between the plurality of apertures 41. The airtight sealing element 42 is selected as an elastic material, such that the airtight sealing element 42 elastically seals and closes the apertures 41.

Referring to FIG. 5, in case that the external pressing force 30 is applied to press down the bladder 10 and the elastic restoration device 11 (such as the human head moving away from the bladder 10), the elastic restoration device 11 generates a negative pressure rebounding force to support the bladder 10, and the air pressure of the bladder 10 sucks backwardly the airtight sealing element 42 of the self-charging valve 40, the airtight sealing element 42, due to the effect of backward suction by the air pressure of the bladder 10, elastically deforms to automatically open the apertures 41 to drawn external air through the apertures 41 into the self-charging valve 40 and then reaching into the bladder 10, so as to automatically recharge air into the bladder 10 for restoration of an original shape thereof, thereby avoiding deformation of the elastic restoration device 11 resulting from elastic fatigue thereof.

In a next use of the bladder 10, the height of the bladder 10 follows the reverse-resisting force adjusted and set by the regulation valve 20 to generate a static equilibrium effect, maintained at a memorized keeping state for being high/low or soft/stiff.

Referring to FIGS. 6 and 7, in an embodiment, the push member 24 is in movable threading engagement with the regulation valve 20.

By rotating the push member 24 to induce movements of different extents for pushing the elastic element 23 to generate different degrees of deformation, the valve diaphragm 22 is made to induce reverse-resisting forces of different magnitudes for resisting the air pressure of the bladder 10 to achieve an effect of adjusting the supportability and height of the bladder 10 based on personal needs, meaning the extent of softness/stiffness of the bladder 10 can be adjusted.

Further, after the adjustment of the supportability and height, the bladder 10 may automatically position and shape based on an effect of negative pressure. For example, when a human head lies on the bladder 10, in addition to the adjustment of the supportability and height of the bladder 10 based on personal needs, the automatic positioning and shaping of the bladder 10 makes it more snugly around the human head to enhance comfortability.

Referring to FIG. 8, in an embodiment, the regulation valve 20 and the self-charging valve 40 are integrated and combined as a one-piece structure.

Referring to FIG. 9, in an embodiment, the push member 24 is arranged on the regulation valve 20 in a pushable manner.

Through pushing and moving the push member 24 to achieve displacements of different extents the elastic element 23 is pressed to generate different degrees of deformation, so that the valve diaphragm 22 may resist the air pressure of the bladder 10 with reverse-resisting forces of different magnitudes.

At the contact site between the regulation valve 20 and the push member 24, a wavy and ridge-like corrugation engagement structure may be arranged for automatic positioning of the push member 24 after the displacement.

Referring to FIG. 10, in an embodiment, the regulation valve 20 that is provided with the pushable push member 24 is integrated and combined with the self-charging valve 40 as a one-piece structure.

The central bladder 10 is provided with an air tube 12 for communication between interior and exterior thereof, so that when the central space 12 is depressed down, interior air can be discharged with a proper amount.

As such, when a human head lies on the pillow 60, a center-low and two-side-high condition may be presented to be snugger, supporting, and stabilizing the head, meeting human head ergonomics and enhancing stress relief effect.

Further, the regulation valve 20 is in communication with two independent bladders 10, and each of the independent bladders 10 is individually provided with an independent self-charging valve 40.

As such, such a structure is applicable to a pillow and, in the pillow, a plurality of static equilibrium adjusting zones that are each independent of each other are formed. Each one of the independent bladders 10 is of an independent operation for regulation with the regulation valve 20. Air flowing inside each of the independent bladders 10 is not affecting each other. In other words, the pillow may exhibit an effect of adjusting only at the zone that is pressed by the human head, while the other zones that are not in contact with the human head are not showing any effect of adjusting. As such, preciseness of adjustment of each independent one of the bladders 10 is enhanced, and the snugness and comfortability of the pillow are also enhanced.

Referring to FIG. 13, in an embodiment, the self-charging valve 40 is provided, in an interior thereof, with a separation board for supporting an additional airtight sealing element 42, so that when the bladder 10 sucks in air for self-charging, the additional airtight sealing element 42 provides an airtight sealing effect by which the bladder 10 does not suck in gases from the regulation valve 20 and tube lines thereof, so that the sucked-in self-charging air flow of the bladder 10 is more stable and the adjustment of the bladder 10 is made more stable.

Referring to FIG. 14, in an embodiment, a concave surface 211 is formed on a circumference of the valve opening 21 of the regulation valve 20, and the valve diaphragm 22 is provided with a convex surface 221 corresponding to the concave surface 211, and the concave surface 211 and the convex surface 221 match each other to increase a contact area therebetween and to improve positionability. A positioning peg 222 is provided on an underside of the valve diaphragm 22 to extend through the valve opening 21 but not blocking and contacting the valve opening 21, so as to make the valve diaphragm 22 not readily move to a position separating from the valve opening 21.

As such, either in a condition of closing the valve opening 21 or in a condition of being pushed by an air pressure to open the valve opening 21, the valve diaphragm 22 can be retained on and positioned at the valve opening 21 to enhance the preciseness of opening and closing of the valve opening 21 by the valve diaphragm 22.

Referring to FIGS. 15, 16, and 17, in an embodiment, two or more than two sets of bladder 10 and regulation valve 20 are provided, and a box 50 is provided to receive and hold such regulation valves 20 to achieve an aesthetic effect.

As such, different ones of the regulation valves 20 are operable to individually control independent ones of the bladders 10 for application to a pillow product, so that when a human head lies thereon, each of the bladders 10, based on a pressing force acting thereon, may individually adjust the supportability (namely softness/stiffness) and height to enhance preciseness of adjustment of the bladder 10, and the snugness and comfortability of the pillow are also enhanced.

Referring to FIG. 18, in an embodiment, the external pressing force 30 is force that is generated by taking the bladder 10 as an acted body, while an acting body, such as a human body, actively applies a pressure to the bladder 10, such as the bladder 10 being applied to a chair, a pillow, a mat that are structured for a human body to lie thereon.

Referring to FIG. 19, in an embodiment, the external pressing force 30 is counteracting force that is generated by taking the bladder 10 as an acting body that is moved toward and snugly around an acted body, such as a human body, such as the bladder 10 being applied to various products, such as a neck protector (cover) and a knee sleeve, for being sleeve on human torsos and organs.

Referring to FIG. 20, in an embodiment, the bladders 10 are set in a stacked arrangement, and each of the bladders 10 is in communication with the regulation valve 20 in order to increase a support height and when the external pressing force 30 vanishes, the bladders 10 of the stacked arrangement can be charged with air simultaneously, and the elastic restoration devices 11 inside the bladders 10 of the stacked arrangement simultaneously generate negative pressure rebounding forces to expand the bladders 10 for increasing the speed of restoration back to the original height and shape.

Referring to FIG. 21, in an embodiment, the bladders 10 are set in a stacked and connected arrangement, and the connection site may have an airtight sealing by means of techniques of hot pressing or hot melting. The connected site is provided with a passage hole 13, and air inside the bladders 10 of the stacked arrangement may flow toward each other through the passage hole 13, so that the supporting height can be increased and when the external pressing force 30 vanishes, the bladders 10 of the stacked arrangement can be charged with air simultaneously, and the elastic restoration devices 11 inside the bladders 10 of the stacked arrangement simultaneously generate negative pressure rebounding forces to expand the bladders 10 for increasing the speed of restoration back to the original height and shape.
