WO2018053673A1 - Self-filling cushion capable of quick charge and quick discharge - Google Patents

Abstract

Provided is a self-filling cushion capable of quick charge and quick discharge. The self-chargeable cushion comprises a cushion body. An outside surface layer of the cushion body forms an airtight or watertight sealable capsule in the cushion body. A filler capable of swelling after a pressure or a restriction is released is arranged in the sealable capsule. The sealable capsule communicates with outside air or liquid through one or a plurality of openings relatively larger or much larger than a conventional self-chargeable valve. The opening can be sealed in a coiled or folded manner. When air or liquid is charged, the cushion body swells after the pressure or the restriction is released on the filler, so as to inhale outside fluid. Because the openings are relatively larger or much larger than the normal self-chargeable valve, the instantaneous volume of the inhaled fluid is much greater than that of the conventional self-chargeable valve, so as to quickly charge or discharge air or liquid. When the air or the liquid is discharged, the opening is opened and the fluid in the cushion body can be extruded from the tail end of the sealable capsule to the opening portions. Because the openings are much larger than the normal self-chargeable cushion, the speed for discharging the air or the liquid is much higher than that of the normal self-chargeable cushion.

Description

[Correct according to Rule 26 05.01.2017] A self-filling pad that can be quickly charged and discharged Technical field

The invention relates to a self-inflating pad, in particular to a self-inflating pad which can be quickly charged and discharged.

Background technique

Various beds, mats and linings have been widely used in daily life, sports, industrial and agricultural activities, and the military by inflating or filling liquid in a closed capsule. For example, inflatable cushions used by soldiers or outdoor enthusiasts for camping; airbeds, waterbeds, cushions, toys, etc. used in home or medical care; floating beds used in disaster relief or rescue, and cushions used in industrial and agricultural production.

However, due to the filling and filling of fluids, especially when inflating, various pumps are often used, which brings different degrees of inconvenience to carrying and using. If you do not use a variety of air pump or air pump and only blow by mouth, because the pad body tends to be relatively large, it poses a great challenge to the inflator's lung capacity, physical exertion and comfort after blowing.

U.S. Patent No. 9,395,007 discloses a solution for obtaining aeration effect faster by blowing a certain distance from the air inlet without using a pump; however, the solution is blown farther from the air inlet and the body itself is also Larger, so the maturity and firmness of the mat is not ideal; and there is considerable challenge to the inflated lung capacity, physical exertion and comfort after inhalation.

At present, the self-filling pad with its own expansion inside the pad body, especially the self-inflating pad, has been widely used by outdoor enthusiasts. Compared with the general air cushion, the utility model has the advantages that the air pump or the air cylinder is not required to be inflated, and the mouth blow is not necessary, so that it is relatively simple and convenient to carry and use. When in use, as long as the valve on the self-inflating pad is opened, the inhalation gas can be inflated by the expansion of the internal filling material, and the valve can be used after the valve is closed.

However, the gas nozzles or valves of the self-inflating mats currently available on the market are relatively small, and the practical effective gas passages have a minimum cross-sectional area of only a few square millimeters to several tens of square millimeters. The instantaneous airflow rate that can be passed through when charging and discharging is small, so that the automatic inflation time is long, the charging is not full, the exhaust gas is slow, the exhaust time is long, or the exhausting time cannot be completely exhausted, and the storage volume is too large. At the same time, due to the existence of these shortcomings, the self-inflating pad cannot be fully expanded and the thickness of the cushion body after expansion is also limited to a certain extent, and it is impossible to make a thicker bed or pad; at the same time, the expansion of the density is further limited (or The application of expansion materials with smaller expansion forces but higher expansion rates.

Chinese patent CN204427422U announced that "an inflatable cushion with airtight zipper valve" can better solve the problem of rapid charge and discharge, but there are several obvious problems: the purchase cost of watertight or airtight zipper itself and Installation cost Higher; the airtight performance is easily reduced after long-term use, especially after the roll (or fold) in the process of storage, carrying and/or compression, the airtightness and reliability of the airtight zipper are significantly reduced; As stated in the patent specification, it takes a lot of effort to open and close the zipper, which easily damages the pad body, the expansion body and the zipper itself.

Chinese patent CN202820476U discloses a solution for sealing with a "zipper seal". Although the solution solves the problem of rapid charge and discharge through a large opening, it also has high production cost and low sealing reliability, especially after repeated extrusion in the process of storage and use of the self-inflating pad, which is extremely easy to make " The zipper seals cause problems such as deformation, distortion, and inability to fit well, resulting in a significant decrease in the sealability and reliability of the product.

Therefore, consumers need a self-inflating mat that can combine rapid charging and discharging, simple operation, small storage size, large expansion ratio, high compression ratio, high sealing reliability, and long-term repeated use.

Summary of the invention

In view of the current state of the art, the technical problem to be solved by the present invention is to provide a self-inflating pad for quickly charging and discharging air with a fast charge and discharge and a reasonable design.

The technical solution adopted by the present invention to solve the above technical problem is: a self-filling pad capable of quickly charging and discharging, comprising a pad body and an opening for entering and leaving a fluid, the outer surface of the pad body being airtight or watertight a coating layer forming a sealable capsule in the pad body, the capsule body being filled with a filler which expands after releasing pressure or restraint applied thereto, the size of the opening a combination of one or more of the ways in which the opening can be rolled up, folded, tied, locked, pressed or clamped between 0.1% and 100 times the smallest cross-section of the body of the cushion body Sealed.

Further, a membrane valve for controlling the flow of the fluid is disposed in the opening. The membrane valve not only functions to prevent backflow of fluid when the fluid enters and exits, but when the opening is wound or folded, the membrane valve is simultaneously rolled up and pressed to cut off a passage for fluid leakage; Thereby, the airtightness, watertightness and reliability and durability of the seal can be further improved. The membrane valve can be a pipe structure with two ends open, or a sheet valve valve structure that can be opened and closed.

Further, one or several kinds of splicing means such as a splicing eyelet, a button, a buckle, a strap, a rope or a zipper are arranged on the edge of the pad body, so that one or more different pad bodies can be spliced together. Use as a larger cushion or other special shape such as tents, awnings, floating rafts, boats, etc.

Further, the pad body may be provided with a kind of detachable pillow, storage bag, fixing device, massage device, calling device, sensor, reflective strip, pump or decoration, etc. Or several, so as to be suitable for use in different situations such as camping, travel, home, medical, military, rescue or disaster relief.

Further, the filling body in the pad body is a detachable structure, so that the pad body coating layer is used as a thin pad, a mat, a waterproof pad, a waterproof bag, a water bag and a hollow float after the filler is extracted. Wait for use.

Further, the closable capsules may be one or more. The closable capsule can be separated into mutually independent, independent, and relatively small volumes by further winding the opening to cut the channels that communicate with each other. Capsule. This can increase the fullness of the capsule, reduce the possibility that the pressure-bearing part of the cushion becomes too thin due to the gas displacement inside the capsule; and can reduce the risk of air leakage, because even one or several closed capsules Air leaks or leaks can occur, and several other closed capsules can continue to function.

Further, the self-filling pad is provided with a valve to discharge excess fluid in the case where the opening is squeezed into too much fluid, or to replenish the fluid when the capsule pressure is insufficient to adjust the pressure and fullness of the capsule. Degree, firmness, etc.

Further, a blown or supplemental aeration can be added to the pad through the opening or the inverted membrane valve to achieve greater balloon pressure and better cushion load bearing capacity. It is important to note that this type of supplemental insufflation or supplemental inflation is not an option, but rather an additional option for users who are accustomed to insufflation or physical permission to comply with existing or traditional methods of use. In addition:

Since the pad body has inhaled most of the air by its own expansion, the amount of air required to be replenished or replenished is relatively small, and does not pose a challenge to the user's lung capacity, physical exertion, or comfort after inhalation.

Since the pad body is increased in pressure in the pad by squeezing additional air in the opening or passage, it is not necessary to blow vigorously when replenishing or replenishing the air. The blower only needs to blow the opening, the passage or the valve film that is turned over without causing discomfort, and does not need to blow vigorously. Therefore, there is no challenge to the user's lung capacity, physical exertion, or comfort after inhalation.

Further, the filler in the self-filling pad is provided with a hollow structure to reduce the weight of the pad body and reduce the carrying capacity, improve the comfort of use or realize the shape of the control pad body.

Further, the filler in the self-filling pad can be filled with fillers of different densities or different pressure capacities at different locations, so as to apply different contact pressures to different parts of the human body, thereby improving the comfort of the user or Achieve the purpose of controlling the shape of the pad body.

Further, different capsules may be adjusted in one way or in several ways by adjusting the amount of fluid to be enclosed, replenishing the fluid, releasing some of the fluid that has been enclosed, using fillers of different densities or different pressure capacities, and the like. The combination adjusts the pressure, fullness and comfort of the corresponding capsule.

Further, the shape of the pad body, the density of the pad body and/or the fullness of the different capsules (pressure bearing capacity) and the physiological curvature of the longitudinal direction of the human body and/or the lateral head, neck, shoulders, back, waist, The outer contours of the hips, thighs, calves or feet are matched or opposite. The user can adjust the pressure capacity or softness of each part according to different usage conditions and personal preference to obtain maximum comfort. Some people want to lie down on the back of the lower back and/or the lower leg when they are resting after a long journey or fatigue. Some people just do the opposite. They like to lie down and have less stress on the back and/or lower leg. . The traditional self-filling pad has no other choice because the pressure of different parts cannot be adjusted; and the invention has different capsules which can be separated and the internal pressure can be adjusted, so that the user can strengthen according to his personal preference. Some parts of the support force or reduce the support of certain parts to achieve a personalized and personalized design. This is especially meaningful for outdoor enthusiasts or soldiers after a long journey.

Preferably, the above different parts can be made into a cradle-like structure (high side, low inside), and then the pressure of different parts can be adjusted to obtain the most comfortable and most comfortable use effect for the user after the fatigue outdoor activity. To minimize fatigue.

Compared with the prior art, the invention has the advantages that: by setting a large opening portion, the fluid can enter and exit the sealable space in the mat body with a relatively larger or much larger instantaneous flow rate, and the charging and discharging gas can be obviously accelerated. Speed, easier to use and can use thicker packing to make the pad thicker; it can also be set by conventional air valve, membrane valve, multiple capsules, special shaped capsules, special shape filling Objects, different density fillers, compressible storage pockets, splicable structures, pillows, massage devices, call devices, sensors, reflective strips, pumps, trims, and separation of fillers and capsules The combination means that the product is more convenient to store and carry, more reliable, more user-friendly, and better to use.

The invention is applicable to all fluids, including aeration or liquid filling. Such as self-inflating pads, self-filling water beds, self-filling gels or slurry medical / health beds.

The invention can be applied to outdoor camping, sports, car and boat cushions, home, toys and other daily life; soldiers or field workers; air beds and water beds used in home or medical care; floating beds used in disaster relief or rescue; Cushions used in production, etc.

The invention has reasonable design and can be widely applied to different fields.

detailed description

In order to make the objects, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in FIG. 1-2, a self-filling pad capable of quickly filling and discharging a fluid includes a pad body 1 and an opening 3 for entering and leaving a fluid. The outer skin of the mat has an airtight or watertight coating so that an airtight or watertight closable bladder can be formed inside the mat. The closable capsule in the pad is filled with a filler 2 (e.g., a reboundable sponge, foam, fiber or floe, etc.) that expands upon release of pressure or restraint. The closable bladder communicates with an external fluid (e.g., external air or water) through one or more openings 3 that are much larger or larger than conventional valves. Since the cross-sectional area of the fluid passing through the opening is much larger than that of a conventional valve, the opening 3 can be passed through a relatively large instantaneous flow or flow compared to a conventional valve to achieve rapid inflation (liquid) or exhaust (liquid) The opening 3 can be effectively and reliably sealed by means of crimping or folding, such as shown in Figures 3-6, 29-31, 35, 44, and 74-83. That is, as with the sealing principle of the waterproof bag which has been widely used, when the cross section AA' of the opening 3 is closed, the coated cloth constituting the opening 3 is pressed and pressed toward the capsule direction (that is, in the direction toward the EE' section). When rolled up, because the inner surfaces of the opening 3 and the cushion coating are coated with a gas-tight or water-tight coating, these air-tight or water-tight coatings are tightly pressed together to cut the fluid in and out of the gasket. The passage of the capsule, in particular after repeated crimping and folding, the passage of the fluid in and out is completely cut off, thereby achieving a reliable seal. The more the opening 3 is rolled up or repeatedly folded, the better the sealing effect, reliability and durability.

After the opening 3 is wound up, it can pass through a magic buckle such as that shown in FIG. 4, a Japanese buckle shown in FIG. 5, a zipper shown in FIG. 6, a strap shown in FIG. 30, and a drawing shown in FIGS. 49-54. Fixing in a manner similar to the waterproof bag sealing structure to prevent the opening 3 of the rolled up seal from being loosened to cause air leakage or liquid leakage.

Preferably, a membrane valve 10 composed of a membrane structure can be disposed within the opening 3. The film structure 10 is in addition to the fluid In addition to the effect of preventing backflow of fluid during entry and exit (as shown in Figures 27-28, 33-34 and 37), the film structure 10 is simultaneously flattened when the opening 3 is wound up. The leaking channels are rolled up and pressed against each other inside the opening to further block the fluid (as shown in Figures 29-30, 35 and 44). Therefore, the airtightness, watertightness and reliability of the seal can be further improved.

Preferably, the membrane valve may be a cylindrical or mesa structure in which both ends are through holes (also large openings), and an opening of the membrane valve is completely and sealingly heat-sealed into the openings 3 or/and 33 edge. When the cushion body inhales the outside air, the outside air can enter the cushion body through the membrane valve without difficulty (as shown in Figs. 27, 32 and 36). When the pad body is filled with sufficient air, the pressure inside the pad body is higher than or equal to the external atmospheric pressure, and the membrane valve 10 is automatically closed by the internal and external pressure difference and/or its own gravity. Thus, the air inside the pad is prevented from escaping (as shown in Figures 33-34 and 37). When it is necessary to vent or use the membrane valve 10 to replenish additional gas, the membrane valve 10 can only be pulled out (flip) in reverse by hand to achieve rapid venting (as shown in Figure 28) or to supplement additional gas (as shown). 40)).

As shown in Figures 41-43, the membrane valve can also be a simple one-piece membrane valve 105, as long as the fluid passage is sufficiently large to not affect the fluid ingress and egress rate and the membrane valve is closed without leakage.

The opening 3 can be rolled up (as shown in Figures 3-6, 29-30, 35, 44 and 74-83), pressed (as shown in Figure 31), folded, etc. Use one or several ways in combination (as shown in Figures 49-54) to seal.

Preferably, the openings 3 may also be stuck to each other by the clicker 11 and/or the card slot 12 to be sealed and rolled up to obtain a sealing effect. The clicker bar 11 and/or the card slot 12 can be used as a reel for winding up the pad body when in the stowed condition to more exhaust the gas in the pad body for a smaller storage and carrying size. Preferably, the clicker 11 can also be designed as an extra-sized extra air pump (inflator) or the like to achieve a multi-purpose use. In addition, the bar 11 and/or the card slot 12 can also be designed as an antenna-like retractable structure to reduce the carrying and receiving volume.

As shown in FIGS. 23-24, 81, and 83, the number of the openings is not limited to one, but may be set to be plural as needed.

As shown in Figures 23-24, the position of the opening is not limited to the head or foot of the pad body, but may be placed at any suitable position on the top, bottom, left and right, and/or front and rear of the pad as needed.

As shown in Figures 12-15, the opening 3 can be made relatively long and/or relatively large, with a certain space 32 being reserved between the opening 3 and the expansion 2 so that the upper surface of the opening can be lifted by The method draws in more air and eventually squeezes into the expansion 2 to the high cushion 1 and the fullness, firmness and comfort of the individual capsules.

When inflating, the user can open the opening 3 as much as possible by hand or lift the upper surface of the open end as much as possible to accommodate more air (as shown in Figures 36 and 42); then close the opening 3 and then The entire opening portion 3 is rolled up from the open end to the closed end. In this way, more air is squeezed into the expanded sponge 2 in the pad body (as shown in Fig. 44), thereby further improving the fullness, firmness and comfort of the pad body 1 and each bag body.

Figure 32 is a view showing a side surface of the self-filled mat body covering layer 19 (i.e., without using glue to cover the layer) An embodiment of sticking to an expansion in the pad. Lift the mask 19 by hand to inhale more air. After releasing the hand, as shown in Fig. 33, additional air will be enclosed inside the cushion body. In order to obtain a flat surface of the pad body, the pad body can be turned upside down (as shown in Figure 34), and then the opening is rolled up and fixed tightly to obtain a self-filling with a fuller degree of fullness and firmness of the pad. The mat is for use (as shown in Figure 35).

As shown in Fig. 11, in the case where the inflation fullness requirement is not high, the pad body is thick or/and the expansion property of the expansion product is strong, the space for accommodating extra more air may not be reserved; The sealed space inside all the mats outside the opening is filled with the expansion. That is, the space 32 reserved for accommodating additional air can also be filled with the same density, higher density (to form a pillow) or lower density as the body expansion (so that it can be automatically inhaled without the outer surface of the hand opening). More extra air) of the expansion.

As shown in Figures 38-41, the user can also inflate the cushion body with the opening 3 or the inverted membrane valve 10 that is folded by both hands or inflate the cushion body with a gas pump to obtain a larger capsule pressure. And the body weight bearing capacity. It should be specially pointed out that this kind of supplemental insufflation or supplemental inflation is not a necessary option, but it is a habit to use the mouth to inflate or not affect the physical strength, to give the user a way to comply with existing or traditional methods of use. Extra options. In addition:

Since the cushion body has inhaled most of the air by its own expansion, the amount of air to be replenished or supplemented is relatively small, and does not pose a challenge to the user's lung capacity, physical exertion, or comfort after blowing.

Since the pad body is obtained by squeezing additional air in the opening or passage to obtain an increase in pressure in the pad (instead of an increase in pressure by blowing), it is not necessary to blow vigorously when blowing air. The blower only needs to blow the opening, the passage or the valve film that has been turned over without causing any discomfort, without the need for vigorous blowing. Therefore, this traditional or additional option does not pose a challenge to the user's lung capacity, physical exertion or comfort after blowing.

The cushion body 1 may further be provided with one or more conventional air nozzles 9. Such conventional air nozzles may perform additional blow-blowing after the openings 3 are closed to further improve the fullness and firmness of the cushion body. And the comfort of use; it is also possible to let off too much gas in the case of too much opening/squeezing gas to avoid damage to the pad and/or adjustment of the capsule due to too much gas being sealed. Fullness, firmness and comfort.

The filling sponge 2 (expanded material) in the mat body may be punched with holes or other various specific spatial structures to reduce the average density of the foam sponge and the total weight of the filler, reduce the material cost, and reduce the storage and transportation space. Easy to store and carry.

An air pillow 8 (shown in FIG. 9, FIG. 30, FIG. 47, FIG. 49, FIG. 51-52, FIG. 57, FIG. 78-83) may be disposed on the cushion body 1, and the air pillow 8 may be disposed on the air pillow 8. A separate air valve 91 (shown in Figures 49 and 51). It is also possible to provide a pillow that continuously communicates with the internal space of the self-filling pad (there is no isolation valve between them, as shown in Figs. 47, 79 and 82) or temporarily communicated when inflated, and after being inflated, the valve is closed or folded. Pillows in which the space within the pillow is maintained independently and/or under different pressures (as shown in U.S. Patent Nos. 2,372,218, 2,423,890 and US Pat.

Preferably, as shown in FIG. 30, the opening portion 3 can be pressed under the pillow or the cushion body after being wound up to further The high sealing performance allows the sealed capsule to withstand more pressure and better prevent fluid leakage.

As shown in Figures 21-26, if the opening 3 is sufficiently large after being rolled up, it can be used directly as a pillow.

Preferably, as shown in FIGS. 7-10, 13-16, 19-26, 45-47 and 57-83, the confined space in the pad body may be divided into a plurality of relatively small capsules. . When the opening 3 is wound up, the openings 33 of these relatively small capsules are also simultaneously wound up and sealed. In this way, each of the relatively small capsules can be sealed independently of each other, which not only improves the fullness of the cushion body, the degree of inflation and the comfort of use, but also reduces the risk of air leakage and failure. The reasons are as follows:

The reason why the relatively small sealed capsules that are separated from each other can improve the fullness of the cushion body, the degree of inflation and the comfort of use are as follows: when the sealed space in the cushion body is a large whole (as shown in FIG. 17) The fluid on the underside of the pressure receiving portion of the pad is squeezed under pressure to other uncompressed portions (as shown in Figure 18). Therefore, unless the internal pressure is sufficiently large (the higher the pressure, the higher the requirements on the mechanical properties and pressure resistance of the cushion material, the higher the corresponding material and production cost, and the more difficult the inflation. Large; therefore, the required inflation effect should be obtained under the lowest possible pressure), otherwise the upper, lower and filling sponges of the pad body can be easily squeezed together after the force is applied, and the front is present. The unfavorable situation of sticking the back. That is to say, the fluid and/or expansion in the pad fails to function as a support for the design, and there is an uncomfort similar to sleeping directly on a "hard bed" or similar to sitting directly on a hard floor ( As shown in Figure 18). The main reason for this problem is that the closed space in the pad body is too large, and the expansion of the capsule body becomes larger and the amount of shrinkage after the fluid is compressed is also relatively large, and the inside of the pad body is closed. The fluid (especially the gas) has enough space to flow to other unstressed locations (as shown in Figure 18). Once the confined space is divided into a plurality of relatively small closed capsules that are not connected to each other, especially when the mutually non-connected and relatively small capsules are smaller in area of projection than the area of the human body contact surface (force surface) The space for the fluid to flow or escape in the relatively small closed capsule is relatively small or absent, and the amount of expansion and contraction of the capsule is also suppressed due to the smaller total surface area, and the gas deformation of the capsule body is suppressed. The amount is also suppressed by the fact that the amount of closed gas is significantly reduced. Therefore, only by the compressibility of the gas (or liquid) in these relatively small spaces, the gas or liquid in the closed capsule can fully exert the bearing function (as shown in Fig. 19), so that the small capsule can withstand the pressure ( That is, the carrying capacity) is significantly improved.

If the mutually unconnected and relatively small capsules have a projected area smaller than the contact surface area in contact with the human body (ie, the entire small capsule is completely covered by the force receiving surface), it is sealed in these relatively small closed capsules. The gas (or liquid) will always have a load-bearing effect even if it has a certain amount of compression. This avoids or reduces the occurrence of discomfort such as "back-to-back", "sleeping on a hard bed" or "similar to sitting directly on a hard floor." Therefore, the more the sealed space of the pad body is divided into more independent small capsules, the better the overall weight-bearing effect of the pad body. The corresponding mat fullness, firmness and ease of use will be better. Of course, the more separate capsules are separated, the more difficult and costly to manufacture. Therefore, a reasonable separation capsule size, shape and/or number is required depending on the application and cost budget. The roll-up structure of the present invention can well solve this conflict, and obtain as many as possible small capsules without increasing the manufacturing cost and simplifying the use procedure, and the large-sized cushions composed of the mutually independent small capsules .

In addition, after the sealed space in the pad body is divided into a plurality of sealed small capsules that are not connected to each other, even if one or several closed capsules are punctured or leaking/leaking, there are many others. A closed capsule can continue to function. Therefore, after the mat is divided into a plurality of relatively small independent bladders that are not connected to each other, the risk of air leakage or overall failure of the self-filling mat can be significantly reduced.

Preferably, as shown in Figures 8, 10 and 13-15, the openings 33 of the mutually independent sealable capsules may be disposed between the openings 3 and the expandable filler 2, and in both A sufficient distance is left to form a space 32 (i.e., a space between the section CC' and the section DD' in which the opening is not rolled up, that is, the small space II in Fig. 46 ', III', IV', small spaces II', III', IV', V', VI') in Figures 78-83. That is, the opening 3 is divided into two portions by the plurality of openings 33 of the mutually independent and relatively small sealing capsules: the integral fluid passage 31 of the pad body and the plurality of gas streams of the sealing capsules which are independent and relatively small. Channel 32. When the opening 3 is rolled up, it can be rolled up to the extent that the integral opening 31 will be wound up but not completely wound up, that is, the AA' section has been tightly sealed and the CC' section has not been wound up yet (ie, The mutually independent and relatively small capsule openings 33 have not been wound up, and then ventilated or deflated by a conventional gas valve 9 as needed, so that all small capsules that are not yet independent of each other are equivalent The pressure is filled with gas; after the qi or deflation is completed, all the openings including the relatively small capsule opening 33 are continuously wound (ie, the opening 3 continues to be wound in the EE' direction, and the CC' section is also wound up and Sealed until it is rolled up to the DD' section, these relatively small capsules can be separated from each other without communication, thereby realizing the separation of the large cushion body into a plurality of small capsules independent of each other.

Further, in order to achieve different pressures for different capsules, the channels 32 of the separated small capsules can be divided into spaces of different sizes (such as spaces II', III' shown in FIG. IV', spaces II', III', IV', V', VI') shown in Figures 79-83. When these different sized spaces are rolled up, the different volumes of additional fluid within them will be squeezed into the corresponding spaces in communication therewith (see spaces II, III, IV as shown in Figure 46, Figure 79- Spaces II, III, IV, V, VI) shown in 83). Finally, these small capsules result in different internal final pressures due to the different amounts of fluid that are eventually squeezed in, so that different small capsules ultimately achieve different load carrying capacity (pressure resistance). The method for obtaining different pressures of different capsules by squeezing different reserved spaces is further described below with reference to Figs. 45-47:

As shown in Fig. 45, since the openings of the capsules II, III, and IV are uniform in size, after the AA' section is rolled up, the extra gas in the space I is pressed into the capsules II, III, and IV in an equal pressure manner. After the completion of the winding, the pressures in the capsules II, III and IV of the examples were equal. At this time, in addition to reducing the risk of failure of the entire cushion due to air leakage in a certain part, small capsules with different pressures are not obtained.

However, as shown in Fig. 46, if the openings of the spaces II', III', IV' are of different sizes, the volume of these spaces will also vary in size: the space III' contains the most extra gas, the space II' and The amount of additional gas contained in IV' is relatively small. Before the AA' section is rolled up to the section CC', the extra gas in the space I is pressed isostatically into the capsules II+II', III+III', IV+IV', at which time the capsules II, III The pressure increase in IV is equal. When the opening is wound through the section CC' to obtain the sealing effect, the gas in the space II' will be squeezed into the space II, and the gas in the space III' will be squeezed into the space III, empty The gas in the IV' will be forced into the space IV. Since the space III' contains more extra gas than the space II' and IV', when the opening is rolled to the C"C" section to obtain a sealing effect, the pressure in the capsule III is higher than that. The pressure of capsules II and IV is high, so the load-bearing capacity of capsule III is better than that of capsules II and IV.

Figure 47 is a schematic illustration of another different load carrying capacity of different capsules obtained by different sized extruded spaces. Due to the different opening sizes of the spaces II, III, IV and V+VI and the order in which they are rolled up, the amount of additional gas contained in these spaces varies. Before the AA' section is rolled up to the CC' section, the extra gas in space I is compressed into all other small spaces, at which point the pressure rises in each capsule are equal. When the opening is wound through the CC' section to obtain the sealing effect and continues to be entangled in the EE' section, the pressure in the space II is significantly increased, and the gas in the other space is increased by the same pressure in the relative II but the same as the increase in the pressure ( At this time, the pressure increase of other small spaces will be smaller than that of space II). After continuing to squeezing to the C ₂ C ₂ 'section to achieve a sealing effect, the pressure increase in space III is greater than that in spaces IV and V, but less than the pressure increase in space II. After the sealing effect is obtained by winding the C ₃ C ₃ ' section, the differential effect of the pressure P in each of the differently opened capsules is "P _II > P _III > P _IV > P _V = P _VI ".

Therefore, in addition to the additional inflation or deflation can be used to adjust the pressure (load bearing capacity) of different capsules, different pressures of different capsules can be obtained by setting the size of the extra gas channels (accommodation spaces) of different independent capsules. (Load capacity). By using one or more of the various ways described above, different load bearing capacities can be obtained in the mat body according to the required regularity.

Based on the above principle, we can achieve the pressure bearing capacity of different parts of the pad body and the physiological bending of the human body by adjusting the shape of the pad body, the density of the filling material and/or the fullness (pressure bearing capacity) of different capsules. The lateral contours of the head, neck, shoulders, back, waist, hips, thighs, calves or feet of the human body are matched (corresponding or relatively), and the user can adjust the pressure bearing capacity of each part according to different usage conditions and personal preferences. Or softness and hardness for maximum comfort (as shown in Figure 55-56). When resting after work, some people hope that the contact surface between the human body and the pad body can be evenly stressed after lying down (as shown in Figure 55), while others will want more force on the lower back and/or lower leg ( As shown in Figure 56, some people just do the opposite. They like to lie down and have less stress on the back and/or lower leg. Even different users are more or less stressed on the same part. The opposite of different preferences (as shown in Figure 70--73). The traditional self-filling pad can not adjust the pressure of different parts, the user has no choice: either the whole body is hardened at the same time, or the whole body is soft at the same time; and the invention can be separated and the internal pressure can be separated Adjusting the different capsules allows the user to strengthen the support strength of some parts according to their personal preferences or reduce the support force of some parts to realize the humanized and personalized design. This is especially meaningful for outdoor enthusiasts or soldiers after a long journey.

Preferably, by providing small capsules of different shapes and sizes, the cushion body can be made into an ergonomic mummified shape, similar to a baby cradle structure ("side height, low interior", as shown in Fig. 58--67 Shown), or "low side, middle height" structure (as shown in Figures 62-65, 68 and 82), or even "the middle of the spine bearing part and both sides are high and enlarge the leg calf And the heel and other parts Low" (as shown in Figure 69 and Figure 83) and other structures that allow people to rest more comfortably, and then adjust the pressure of different parts to give the tired user the most comfortable use and minimize fatigue .

The term "high" or "low" as used herein refers not only to the spatial extent of the capsule and its cross-section, but also to the density, internal pressure and/or load carrying capacity of the filler in the mat. As shown in Fig. 70 and Fig. 72, when not in use, the surface of the pad body may be a flat plane, and the spatial height of different capsules is not seen; the density of the inflated bodies in the capsule body at the time, the pressure inside the capsule body. And / or the carrying capacity of the capsule is high or low.

The following are some specific examples:

As shown in FIG. 70, the filler density or pressure of different portions of the pad body may be different; different density fillers 21, 22, 23 may exert different supporting forces on different contact faces between the pad body and the human body (ie, Different carrying capacity).

As shown in Fig. 71, the density or pressure of the filler in different parts of the pad body may be different, and the shape of the pad body is matched with the contour of the human body for better use.

As shown in Fig. 72, the density or pressure of the filler in different parts of the pad body may be different, and the shape of the pad body is opposite to the contour of the human body to suit different usage preferences.

As shown in FIG. 73, in another embodiment of the present invention, the density or pressure of each part of the pad body is different and does not correspond to the physiological curvature of the human body, and there is a correspondence and a relative.

Figure 74 is a schematic illustration of an embodiment of an octagonal self-filling pad of the present invention. This type of self-filling pad has a narrow head, a wide shoulder, a chest, abdomen and hip, and the leg to the foot gradually become smaller, matching the projection contour of the human body. Reduce the amount of raw materials, reduce the overall weight and storage size.

Figure 75 is a view showing an embodiment in which an octagonal self-filling pad of the present invention is divided into mutually independent capsules.

Figure 76 is a view showing the above-described octagonal self-filling pad of the present invention being separated into mutually independent capsules and "the bladder pressure in the middle after sealing is high and/or the packing density is large, and the capsule pressure on both sides is low. Examples of and/or low packing density".

Figure 77 is a view showing an octagonal self-filling pad embodiment of the present invention, the inside of which is divided into mutually independent capsules and "after sealing, the outer capsule has a high pressure and/or a high density of the filling, and the inner capsule Low pressure and/or low filler density (similar to the structure of a baby cradle).

Figure 78 is a view showing a mummified self-filling pad embodiment of the present invention, in which the inside of the pad body is divided into mutually independent capsules, and the different capsule bodies are in the shape of the longitudinal physiological bending of the human body and the cross-sectional contour of the human body. The density of the capsules is equal pressure or / and filler, cradle-like structure.

Figure 79 is a view showing another embodiment of the mummy-shaped self-filling pad of the present invention, in which the inside of the pad body is divided into mutually independent capsules and "the different capsules are in the shape and the longitudinal physiological curvature of the human body and the cross-sectional profile of the human body. All are matched (by designing different opening sizes, the capsules are not equal in pressure but the density of the filling is equal, cradle-like structure).

Figure 80 is a view showing still another embodiment of the mummy-shaped self-filling pad of the present invention, in which the inside of the pad body is divided into mutually independent capsules, and the different capsules are in the shape and the longitudinal physiological curvature of the human body and the cross-sectional contour of the human body. Consistent; each capsule is not equal pressure and / Or the fillers are not equal in density, the outer height is low, and the cradle-like structure.

Figure 81 is an illustration of the embodiment of Figure 80 which is realized by squeezing a shared opening, but by squeezing a combination of a plurality of different small capsule openings or small capsule openings to achieve separation of the mummified self-filling pad into The different capsules of each other are in conformity with the longitudinal physiological curvature of the human body and the cross-sectional contour of the human body; the capsules are not equal in pressure and/or the packings are of different density, the outer height is low and the cradle-like structure.

Figure 82 shows another embodiment of a mummy-shaped self-filling pad, in which the inside of the pad body is divided into mutually independent capsules, and the different capsule bodies are in conformity with the longitudinal physiological curvature of the human body and the cross-sectional contour of the human body; The capsules are not equal in pressure and/or the fillings are unequal in density, and the outer height is low. That is, the spine is naturally lifted according to the physiological curvature of the human body to facilitate relaxation and relieve fatigue.

Figure 83 shows a further embodiment of a mummy-shaped self-filling pad in which the inside of the pad body is divided into mutually independent capsules, the different capsules conforming to the longitudinal physiological curvature of the human body and the cross-sectional contour of the human body; The capsules are not equal in pressure and/or the unequal density of the filler, and the position and pressure on the lower part of the spine and on both sides are high, and the position or pressure of the transition between the two is low. That is, the spine portion is naturally lifted according to the physiological curvature of the human body, and the legs and/or the back of the foot are relatively lowered to facilitate relaxation and relieve fatigue.

The embodiment shown in Fig. 83, like the embodiment shown in Fig. 81, does not split and seal the mummified shape by squeezing a shared opening but by squeezing a combination of a plurality of different small capsule openings or small capsule openings. Self-filling the space inside the pad and adjusting the pressure of different capsules.

The various self-filling pads shown above utilize the large opening of the present invention and the manner in which it is rolled up and closed, making full use of ergonomics and different use preferences of different individuals and designing for different environments; regulating human body and cushion body Contact surface contact (bearing) pressure, humanized to achieve the best use of results.

Figures 49-54 show the structure of several imitation waterproof bag sealing openings.

As shown in Fig. 49, at the outer edge of the opening 3, a loop of webbing or strip 14 is provided by sewing or hot pressing. A male end 151 and a female end 152 of a latching structure are respectively disposed at both ends of the webbing or strip 14.

As shown in FIG. 51, when the male and female ends of the buckle can be fastened when the air is filled and discharged, the loop structure formed by the webbing or the strip 14 can expand the opening 3 more and better. It is more conducive to air in and out, faster inflation or exhaust.

After the inflation is completed, the webbing or strip 14 is tightly wound in the direction of the mat body (ie, toward the EE' cross-section), and the male and female snaps of the webbing or strip 14 are buckled after being wound up. Tight, the self-filling pad can obtain a good sealing effect. This sealing method has been widely used in outdoor products such as waterproof bags, and is a highly reliable and low-cost sealing method.

Preferably, as shown in FIG. 50, in order to further facilitate compression and reduce the storage volume, the webbing or strip 14 may not be hot pressed or sewn on the opening 3, but rather a belt loop structure similar to that on the pants. 16 to control the position of the webbing or strip 14. When desired, the webbing or strip 14 is threaded into the belt loop structure 16 to perform its function as shown in Figures 49 and 51. The webbing or strip 14 can be withdrawn from the belt loop structure 16 when not in use or stored. In this way, not only can the storage volume be further reduced and the compression can be facilitated, but the webbing or strip 14 can also be used. The locks 151 and 152 and the like are used as a tie for the compression package or other bundles, tie ropes, etc., to achieve a multi-purpose use.

The belt loop structure 16 can also be replaced with a simple tube (cuff) structure. The webbing or strip 14 is used through the tube when it is needed for use; the webbing or strip 14 is withdrawn from the tube during storage for convenient storage, and the webbing or strip 14 is also It can be used as a tie for compression packaging or other binding, tightening ropes, etc.

Fig. 52 is a view showing another example of the state in which the imitation waterproof bag opening and the opening and the pillow are both detachable structures, and the respective portions are separated and assembled.

As shown in Fig. 53, in this embodiment, the opening 3 is formed as a detachable two-hole through-hole bag body. When necessary, as shown in Fig. 52, the opening may be connected to the opening of the pad by a zipper, a strap or a buckle to perform the function of squeezing additional air or sealing (directly when inhaling or discharging gas) This long opening 3) is not necessarily required by the use of a short, large opening in the pad. In order to achieve no air leakage when the long opening 3 is squeezed with additional air or a tight seal, as shown in FIG. 54, a sufficiently long cylindrical or table-like membrane valve 101 may be disposed in the long opening 3, in the mat. A cylindrical or mesa membrane valve 102 of sufficient length is provided in the short opening of the body. After the long opening 3 is securely fixed to the cushion body by a zipper, a strap or a buckle, etc., the membrane valve 101 and the membrane valve 102 are slid together as shown in FIG. 54 (ie, the membrane valve 101 is entirely or large. Part of the membrane valve 102 is included or covered after being turned over, so that it can squeeze additional air or achieve sealing. Of course, the detachable long openings shown in Figures 52-54 can be more than just one but a plurality. The design function is achieved by connecting the dragon or connecting different detachable long openings to different parts of the pad body.

Although the detachable opening 3 shown in Fig. 53 increases the material and manufacturing cost, it can additionally have one or more waterproof bags (the two ends of the opening 3 as shown in Fig. 53 are rolled up and sealed, that is, a complete usable Waterproof bag). Because it has openings at both ends, it is especially suitable for storing extremely long objects. In addition, the detached long opening 3 can also be used as a storage bag or a compression bag of the self-filling pad after being stored;

Preferably, the filler in the self-filling pad can be made into various hollow structures or other special shapes in order to reduce the weight of the pad body, reduce the carrying volume, increase the thickness of the pad body, improve the comfort of use or realize the control pad. Body shape and other various purposes. There are many ways to fill the filler, including many of the programs disclosed in the expired Chinese patent CN2462778Y.

Preferably, the pad body is provided with a ties, a button, a buckle, a zipper or an eyelet 13 and the like which can be used for splicing, so as to splicing one or more different pad bodies into a larger pad body and double layer. Or a multi-layer mat (as shown in Figures 21-26) can even be used in other special shapes such as tents or floating rows (as shown in Figure 84) or sunshades or arches (shown in Figure 85).

Further, the pad body may be provided with a pillow, a storage bag, a massage device, a calling device, a sensor, a reflective strip, etc., so as to be suitable for use in different situations such as camping, traveling, home, medical, rescue or disaster relief.

Further, the filler 2 in the pad body 1 can be extracted to use the pad outer bag as a thin pad, a mat, a waterproof pad, a waterproof bag, a water bag or a temporary float.

Further, the outer bag of the self-inflating pad can be made in a manner similar to a sleeping bag compression bag so that it can be put away after being stowed The self-filling pad makes the storage volume smaller and more convenient to carry and store by compressing and tightening the strap. The webbing used to tighten or bundle the compression bag may be a webbing 14 that is withdrawn from the opening shown in FIG.

Preferably, the sealed capsules which are independent of each other can be sequentially adjacent to each other in the horizontal direction as shown in FIGS. 7-10 and 13-14, and can also be arranged as shown in FIG. In the vertical direction, the adjacent rows are alternately staggered.

Preferably, the structure possessing the multi-layered sealed capsules can be made into a honeycomb, honeycomb-like or any other structure.

Preferably, the adjacent closed capsules arranged in the vertical direction are mutually staggered, and the joints 18 between the adjacent sealed capsules are shielded for better cold insulation effect and better. Prevent the occurrence of uncomfortable situations such as the aforementioned "back-to-back".

In order to better compare and explain the cold insulation effect of different structures, as shown in FIG. 20, since the joint between the adjacent sealing capsules is directly bonded to one or more surfaces of the cushion body, a bonding pattern 18 is provided. When the self-filling pad is used in a cold environment, the bonding pattern 18 is thinner than other air and sponges in the middle, because the thickness is too thin and no other sponge covers or blocks, the body heat is It is easy to be conducted out from between these joints, and the cold flow from the outside will invade from these joints as well, so that the self-filling mat can be kept warm and cold-proof. To this end, as shown in Fig. 15 or Fig. 16, when adjacent closed capsules are staggered, the joints 18 between adjacent sealed capsules of the same level are sealed by different levels of the capsule and its interior. Covered or obscured by the filler. Thereby, heat is prevented from being excessively lost along the embossing pattern 18 and cold flow is prevented from easily intruding from the embossed line 18. In this way, when used in a cold environment, the cold insulation performance of the mat body can be better exerted to improve user comfort and avoid danger.

In addition, different mats can also achieve one or more purposes such as "improving the cold insulation performance, improving the comfort of the user and reducing the risk" by stacking. Figures 21-26 are several of these embodiments.

The number and size of the independent sealed capsules of the two self-filling pads shown in FIG. 21 are different. By adjusting the number and size of the independent sealed capsules, all the bonding patterns 18 can be realized after being stacked. The sealing air and filler in the other layer of the cushion are shielded, and heat is prevented from being lost through the joint or cold air is intruded through the joint.

In addition, as shown in FIG. 21, by adjusting the number and size of the independent sealed capsules, the protruding portion of one of the cushion bodies can just fall into the concave portion of the other cushion body, and even if the stitching between the different levels of the cushion body is not used, the stitching is not used. The eyelets 13 are connected, and the upper and lower cushions are also well engaged with each other to avoid easy relative movement.

Preferably, as shown in Figures 22, 24 and 26, a multi-layer self-filling pad can also be obtained for a single or relatively small person by folding a large size self-filling pad for two or more people. This type of embodiment can be used not only as a double self-filling pad and a single-layer self-filling pad, but also as a double-layer or multi-layer self-filling pad suitable for use in a cold environment.

Figure 24 shows a double self-filling pad, the relatively small independent capsules are arranged on the pad body in two halves, and are vertically disposed and laterally disposed, respectively. When the pad body is opened, it can be used by two or more people as a single layer pad, and after folding, it becomes a double layer pad which can be used by a single person, and the direction of the joint grain is perpendicular to each other to improve the cold resistance performance.

As shown in Figures 23-24, 81 and 83, the number of openings and the position of the opening and the pillow obtained by winding up through the opening The number and position of the heads can be flexibly arranged arbitrarily according to the specific shape and use of the mat. In particular, one or several openings of the separate capsules that are separated within the pad body can be flexibly combined and aligned (as shown in Figures 81 and 83).

Fig. 26 shows another double self-filling pad, in which the relatively small independent capsules are arranged separately in the left and right halves, and are arranged in different directions. When opened, it can be used as a double-layer mat for double use. After folding, it can be used as a double-layer mat for single use, and the direction of the joint is arranged to cross each other.

In addition, the pad body can also be made into a three-fold or even multi-fold structure, and the corresponding joint pattern can be superimposed in a crisscross manner in various complicated ways (and the joint pattern does not necessarily have to be a straight line, and other such as a curved line, a curved line, a broken line) Or profiled lines can be). In order not only to obtain better cold insulation effect, but also to obtain better inflation fullness, cushion hardness and comfort.

Compared with the prior art, the invention has the advantages that the invention can facilitate the gas to enter and exit the airtight portion with a relatively larger or much larger instantaneous flow rate by setting a large opening portion, so that the speed of charging and discharging gas can be obviously accelerated. It is more convenient to use and can use the denser packing to make the pad thicker. It can also be set by conventional gas valve, membrane valve, multiple capsules, special shape cushion, special shape capsule, special Shaped fillers, fillers of different densities, compressible storage pockets, splicable structures, pillows, massage devices, call devices, sensors, reflective strips, pumps, trims, and detachable fills and capsules A series of different combinations, to achieve a more convenient storage and carrying of the product, more reliable use, more humane, better use and a series of improvements and optimization.

The above description is not intended to limit the invention, and the invention is not limited to the above examples or embodiments, and any changes, modifications, additions or substitutions made in the technical field and within the scope of the invention are also The scope of protection of the present invention.
