Static balance adjustment system and method

Abstract

A static balance adjustment system and method includes a bag and an adjusting valve. The internal space of the bag has an elastic recovery device to withstand external pressure. The adjusting valve is connected to the bag and provides an adjustable check resistance to resist the air pressure generated towards the adjusting valve after the bag bears external pressure. The external pressure presses down on the bag and the elastic recovery device. By selecting bags with different internal spaces and elastic recovery devices with different densities and elasticities, different negative pressures and rebound forces are generated. Combined with the balancing force generated by the adjustment setting of the adjusting valve, the bag has a negative pressure difference support force, so that the external pressure, the bag, and the adjusting valve form a static balance. Thus, the support (i.e., softness / hardness) and height of the bag can be adjusted, and the bag can automatically position and shape itself by the negative pressure after adjusting the support and height.

Description

Technical Field

[0001] This invention relates to an adjustment system and method, and more particularly to a static balance adjustment system and method in the field of bag technology. Background Technology

[0002] Inflatable and deflated airbags and air cushions are commonly used in many products such as cushions, pillows, and mattresses. They are typically equipped with a valve body, which controls the intake and desorption of air in the airbag or air cushion by opening and closing the valve port of the air chamber inside the valve body.

[0003] However, when using airbags and air cushions, if the human body, such as the head or body, applies pressure to the airbag or air cushion, the valve body can only perform the function of deflating the air. It cannot respond to the different pressures (such as the weight of the head or body) on the airbag or air cushion and resist the air pressure of the airbag or air cushion with different magnitudes of reaction force. Therefore, it cannot adjust the support (i.e., softness and firmness) and height of the airbag or air cushion according to individual needs, and the range of products that can be applied is limited and the practicality is poor.

[0004] Therefore, the current structure and function of airbags and air cushions are still not ideal. Summary of the Invention

[0005] The purpose of this invention is to provide a static balance adjustment system that uses "static balance" to adjust the support (i.e., firmness) and height of the bag.

[0006] Another objective of this invention is to provide a static balance adjustment method that uses "static balance" to adjust the support (i.e., firmness) and height of the bag.

[0007] To achieve the above objectives, the present invention provides a static balance adjustment system comprising: at least one pouch with an internal space having an elastic recovery device for withstanding external pressure; at least one regulating valve connected to the pouch, providing an adjustable check resistance to resist the air pressure generated towards the regulating valve after the pouch bears external pressure; the external pressure presses down on the pouch and the elastic recovery device, and by selecting pouches with different internal spaces and elastic recovery devices with different densities and elasticities to generate different negative pressures and rebound forces, combined with the balancing force generated by adjusting the regulating valve, the pouch has a negative pressure difference support force, thereby establishing a static balance between the external pressure, the pouch, and the regulating valve. Furthermore, the pouch's support and height can be adjusted, and after adjusting its support and height, the pouch can automatically position and shape itself through the negative pressure.

[0008] The elastic recovery device can be any of the following: foam material, foam, rubber, spring, or spring sheet.

[0009] The regulating valve includes a valve port, a valve plate, an elastic element, and a pusher. The valve port is located inside the regulating valve and communicates with the bladder. The valve plate is used to fit and close the valve port. The elastic element elastically abuts against the valve plate. The pusher is located on one side of the regulating valve and is used to push the elastic element.

[0010] The elastic element is a spring.

[0011] The actuating element is movably screwed onto the regulating valve.

[0012] The actuating element is disposed in the regulating valve in a movable manner.

[0013] The bag is connected to a self-filling valve, which has several openings. An airtight component is provided inside the self-filling valve and between the openings. The airtight component is made of elastic recovery material, which allows the airtight component to elastically seal the openings.

[0014] The pillow can have several pouches arranged in a row within a pillow body, which is then placed inside a pillowcase to form a pillow product. The central pouch is not connected to the pouches on either side, forming an independently operating pouch. The central pouch has an air tube for internal and external communication, and when the central pouch is pressed down, a suitable amount of air can be expelled from its interior.

[0015] The self-inflating valve has another airtight component installed inside the partition, so that when the bag is self-inflating and drawing back air, the airtightness of the other airtight component prevents the bag from drawing in gas from the regulating valve and its pipeline.

[0016] The regulating valve has a concave surface around its valve port, and the valve plate has a convex surface corresponding to the concave surface, so that the concave surface and the convex surface fit together. The valve plate has a positioning post on its lower side that passes through the valve port but does not block it and contacts the valve port.

[0017] The bag and the regulating valve can be in two or more sets, and the regulating valves are housed in a box.

[0018] The external pressure refers to the force generated when the active body actively applies pressure to the bag when the bag is a passive body.

[0019] The external pressure refers to the relative reaction force generated when the sac moves toward and fits tightly against a passive body, acting as the active body.

[0020] The bag is stacked and connected, with a through hole at the joint. The air inside the stacked bags can circulate through the through hole. In addition to increasing the support height, when the external pressure is removed, the stacked bags are also inflated. At the same time, the elastic recovery device inside the stacked bags generates negative pressure and rebound force to expand the bags.

[0021] To achieve the aforementioned other objective, the static balance adjustment method of the present invention includes:

[0022] a. An elastic recovery device is provided in the internal space of a bag to withstand external pressure, and a regulating valve is connected to the bag to provide an adjustable check resistance to resist the air pressure generated towards the regulating valve after the bag withstands external pressure.

[0023] b. Apply the external pressure to the bag and the elastic recovery device, and generate different negative pressures and rebound forces by selecting bags with different internal spaces and elastic recovery devices with different densities and elasticity.

[0024] c. The balancing force generated by the adjustment setting of the regulating valve gives the bag a negative pressure difference support force, so that the external pressure, the bag, and the regulating valve form a static balance. As a result, the bag's support and height can be adjusted, and the bag can be automatically positioned and shaped by the negative pressure after the support and height are adjusted.

[0025] By adopting the above solution, the present invention can respond to different levels of pressure (such as the weight of the head and body) on the airbag and air cushion, and resist the air pressure of the airbag and air cushion with different levels of reaction force, thereby adjusting the support (i.e., softness and hardness) and height of the airbag and air cushion according to individual needs, thus increasing its practicality.

Detailed Implementation

[0047] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the static balance adjustment system of the present invention includes a bag 10 and an adjusting valve 20. The following will describe it in detail:

[0048] The pouch 10 has an elastic recovery device 11 inside to withstand external pressure 30.

[0049] The regulating valve 20 is connected to the bag 10 to provide an adjustable check resistance to resist the air pressure generated towards the regulating valve 20 after the bag 10 is subjected to external pressure 30.

[0050] In one embodiment, the elastic recovery device 11 is any of the following: foam material, foam, rubber, cotton material (such as cotton), synthetic fiber cotton, etc., used to generate a rebound force.

[0051] In one embodiment, the regulating valve 20 includes a valve port 21, a valve plate 22, an elastic element 23, and a pusher 24. The valve port 21 is located inside the regulating valve 20 and communicates with the bladder 10. The valve plate 22 is used to fit and close the valve port 21. The elastic element 23 elastically abuts against the valve plate 22. The pusher 24 is located on one side of the regulating valve 20 and is used to push the elastic element 23.

[0052] In one embodiment, the elastic element 23 is selected from a spring.

[0053] Please see Figure 3 , Figure 4 As shown, the external pressure 30 is applied to the pouch 10 and the elastic recovery device 11. In this embodiment, the external pressure 30 is applied by the head pressing down on the pouch 10 and the elastic recovery device 11. By selecting pouches 10 with different internal spaces and elastic recovery devices 11 with different densities and elasticities, different negative pressures and rebound forces are generated. Combined with the balancing force generated by adjusting the setting of the regulating valve 20, the pouch 10 has a negative pressure difference support force, so that the external pressure 30, the pouch 10, and the regulating valve 20 form a static balance. As a result, the support (i.e., softness and hardness) and height of the pouch 10 can be adjusted, and the pouch 10 can be automatically positioned and shaped by the negative pressure after adjusting the support and height.

[0054] When the external pressure 30 is applied to the pouch 10 and the elastic recovery device 11, if the head is resting against the pouch 10, the valve port 21 generates air pressure and pushes open the valve plate 22, allowing a portion of the air to be discharged through the through hole of the regulating valve 20. After the regulating valve 20 is discharged, the elastic member 23 and the valve plate 22 elastically close the valve port 21, providing a corresponding backflow prevention resistance to resist the air pressure generated towards the regulating valve 20 after the pouch 10 bears the external pressure 30, thus achieving the function of supporting and balancing the pouch 10.

[0055] Please see Figure 2As shown, in one embodiment, the pouch 10 is connected to a self-inflating valve 40, the self-inflating valve 40 is provided with a number of openings 41, and an airtight element 42 is provided inside the self-inflating valve 40 and between the number of openings 41. The airtight element 42 is selected from an elastic recovery device material, so that the airtight element 42 elastically seals the openings 41.

[0056] Please see Figure 5 As shown, when the external pressure 30 does not press down on the pouch 10 and the elastic recovery device 11 (such as when the head leaves the pouch 10), the elastic recovery device 11 generates negative pressure and rebound force to open the pouch 10. The air pressure of the pouch 10 will draw back the airtight part 42 of the self-inflating valve 40. The airtight part 42 can elastically deform due to the air pressure draw back from the pouch 10 and automatically open the opening 41. External air is drawn back through the opening 41 into the self-inflating valve 40 and then into the pouch 10, so that the pouch 10 can automatically re-inflate and return to its original state, which can prevent the elastic recovery device 11 from becoming fatigued and deformed.

[0057] When the bag 10 is used again, the high and low positions of the bag 10 will be balanced by the anti-reverse resistance set by the regulating valve 20, maintaining the memory state between high and low or soft and hard.

[0058] Please see Figure 6 , Figure 7 As shown, in one embodiment, the pusher 24 is movably screwed to the regulating valve 20.

[0059] By rotating the pusher 24 to create different degrees of movement, the elastic element 23 is pushed to produce different degrees of deformation, so that the valve plate 22 can resist the air pressure of the bag 10 with different sizes of backflow resistance, thereby achieving the function of adjusting the support and height of the bag 10 according to individual needs, that is, adjusting the softness and hardness of the bag 10.

[0060] Furthermore, after adjusting the support and height, the pouch 10 can automatically position and shape itself through negative pressure. For example, when the head is resting against the pouch 10, in addition to adjusting the support and height of the pouch 10 according to individual needs, the pouch 10 can fit the head more closely after automatically positioning and shaping itself, thus enhancing comfort.

[0061] Please see Figure 8 As shown, in one embodiment, the regulating valve 20 and the self-filling valve 40 are integrated into a single unit.

[0062] Please see Figure 9 As shown, in one embodiment, the pusher 24 is pushable and disposed on the regulating valve 20.

[0063] By pushing the pusher 24 to move to different degrees, the elastic element 23 is pushed to produce different degrees of deformation, so that the valve plate 22 can resist the air pressure of the bag 10 with different sizes of backflow prevention resistance.

[0064] A wave-shaped or mountain-shaped concave-convex locking structure may be further provided at the contact point between the regulating valve 20 and the pusher 24, so that the pusher 24 can be automatically positioned after adjustment and movement.

[0065] Please see Figure 10 As shown, in one embodiment, the regulating valve 20, which has a pushable pusher 24, and the self-filling valve 40 are integrated into a single unit.

[0066] Please see Figure 11 , Figure 12 As shown, in one embodiment, the pouch 10 may be arranged in three rows and disposed in a pillow body 60, which is inserted into a pillowcase 61 to form a pillow product.

[0067] The central sac 10 is not connected to the two side sacs 10 to form an independent operating sac. The central sac 10 has an air tube 12 for internal and external communication. When the central sac 10 is pressed down, a suitable amount of air inside can be discharged.

[0068] Therefore, when the head is resting against the pillow, it can be positioned with the middle lower and the sides higher to better fit, support, and stabilize the head, conforming to human head ergonomics and enhancing the pressure relief effect.

[0069] In addition, the regulating valve 20 connects two independent bags 10, and each independent bag 10 is equipped with an independent self-inflating valve 40.

[0070] Accordingly, when this structure is applied to a pillow, several independent static balance adjustment zones can be formed on the pillow. Each independent pocket 10 and the adjusting valve 20 operate independently when adjusting, and the airflow within each independent pocket 10 does not affect each other. In other words, the pillow only has an adjustment effect in the area where the head is under heavy pressure, while other areas where the head is not in contact have no adjustment effect. This improves the adjustment accuracy of each independent pocket 10 and also improves the pillow's conformity and comfort.

[0071] Please see Figure 13 As shown, in one embodiment, the self-inflating valve 40 is provided with another airtight component 42 through a partition, so that when the bag 10 is self-inflating and drawing back air, the airtightness of the other airtight component 42 prevents the bag 10 from drawing in the gas from the regulating valve 20 and its pipeline, making the airflow of the bag 10 self-inflating and drawing back air more stable and the adjustment of the bag 10 more stable.

[0072] Please see Figure 14As shown in one embodiment, the valve port 21 of the regulating valve 20 has a concave surface 211 on its periphery, and the valve plate 22 has a convex surface 221 corresponding to the concave surface 211, so that the concave surface 211 and the convex surface 221 fit together, increasing the contact area and improving the positioning. The valve plate 22 has a positioning post 222 on its lower side that passes through the valve port 21 but does not block it and contacts the valve port 21, so that the valve plate 22 is not easy to fall off the valve port 21.

[0073] Therefore, whether the valve plate 22 is closed or opened by air pressure, it can ensure that the valve plate 22 is positioned at the valve port 21, thereby improving the accuracy of the valve plate 22 in opening and closing the valve port 21.

[0074] Please see Figure 15 , Figure 16 , Figure 17 As shown, in one embodiment, the bag 10 and the regulating valve 20 can be in two or more sets, and the regulating valve 20 can be housed in a box 50, thus achieving an aesthetic effect.

[0075] The present invention includes two regulating valves 20, one of which is connected to two independent bags 10 and two independent self-inflating valves 40, with the two bags 10 disposed on both sides, and the other regulating valve 20 is connected to one independent bag 10 and one independent self-inflating valve 40, with the bag 10 disposed in the middle.

[0076] Therefore, different regulating valves 20 can be used to control different independent pouches 10. When the head rests on the pillow, each pouch 10 can adjust its own support (i.e., firmness) and height according to the pressure it bears, which can increase the accuracy of pouch 10 adjustment and improve the pillow's fit and comfort.

[0077] Please see Figure 18 As shown, in one embodiment, the external pressure 30 refers to the force generated when the pouch 10 is a passive body, such as when an active body, like a human body, actively applies pressure to the pouch 10; for example, when the pouch 10 is applied to products such as chairs, pillows, and cushions for the human body to lean against.

[0078] Please see Figure 19 As shown, in one embodiment, the external pressure 30 refers to the relative reaction force generated when the pouch 10 is an active body and moves toward a passive body such as the human body and fits tightly; such as when the pouch 10 is applied to products such as neck protectors (sleeves) and knee braces to fit the human torso and organs.

[0079] Please see Figure 20As shown, in one embodiment, the pouch 10 is stacked, and each pouch 10 is connected to the regulating valve 20. In addition to increasing the support height, when the external pressure 30 disappears, the stacked pouch 10 is also inflated at the same time, and the elastic recovery device 11 inside the stacked pouch 10 generates negative pressure and rebound force to expand the pouch 10, which can accelerate the restoration of the original height and shape.

[0080] Please see Figure 21 As shown, in one embodiment, the pouch 10 is stacked and connected. The joint can be airtight by means of hot pressing, hot melting and other techniques. The joint has a through hole 13, through which the air inside the stacked pouch 10 can circulate. In addition to increasing the support height, when the external pressure 30 is removed, the stacked pouch 10 is also inflated. At the same time, the elastic recovery device 11 inside the stacked pouch 10 generates negative pressure and rebound force to expand the pouch 10, which can accelerate the restoration of the original height and shape.

[0081] Please see Figure 22 As shown, in one embodiment, the elastic recovery device 11 is a spring used to generate a rebound force.

[0082] Please see Figure 23 As shown, in one embodiment, the elastic recovery device 11 is a spring-like piece used to generate a rebound force.

[0083] Please see Figure 1 As shown, the static balance adjustment method of the present invention includes:

[0084] a. An elastic recovery device 11 is provided in the internal space of a bag 10 to withstand external pressure, and a regulating valve 20 is connected to the bag 10 to provide an adjustable check resistance to resist the air pressure generated towards the regulating valve 20 after the bag 10 withstands external pressure 30.

[0085] b. Press the external pressure 30 down on the bag 10 and the elastic recovery device 11, and generate different negative pressures and rebound forces by selecting bags 10 with different internal spaces and elastic recovery devices 11 with different densities and elasticity.

[0086] c. The balancing force generated by the adjustment setting of the regulating valve 20 gives the bag 10 a negative pressure difference support force, so that the external pressure 30, the bag 10, and the regulating valve 20 form a static balance. As a result, the support and height of the bag 10 can be adjusted, and the bag 10 can be automatically positioned and shaped by the negative pressure after the support and height are adjusted.

[0087] The above are examples of embodiments provided in this case for illustrative purposes only and should not be construed as limiting the scope of this case. In other words, all variations and designs made in accordance with the scope of the listed patent applications should be included in the scope of the patents in this case.
