The present invention is the bedding system from the geometry-variable of cooling and self-ventilation.It relates to the structure of several sleeps with annex, includes but not limited to pillow, other similar rest structure and Pet bed.
Pillow
Pillow of the present invention is illustrated among Figure 1A-1C with label 30 generally.Figure 1A-1C shows the multiple view of pillow of the present invention in its pivotally attached pillowcase.Pillow 30 can be opened the monolithic shape-memory material of chamber type (open-cell) structure and makes by having big three-dimensional, is perhaps made by many such materials.Open chamber type structure and make pillow have venting capability, promptly can see through windstream freely, in the clear.All parts and the annex thereof of pillow 30 are breathed freely, and discharge the heat that this health produces before being used for when the heat that health produces occurring and in heat is stored in pillow.Pillow 30 is modular and pivotally attached.
Shown in Figure 1A, 1B and 1C, pillow 30 comprises first periphery wall, 32, second relative periphery wall the 34, the 3rd elongated periphery wall 36 and the 4th elongated relative periphery wall 38.Pillow 30 is made of a plurality of modular cores.Pillow 30 has intermediate core 33, and external core 31,35 and intermediate core 33 are placed side by side.In a plurality of cores 31,33,35 each is all inserted core retainer plate 50 (Fig. 5 A-5C), and this core retainer plate 50 inserts pillowcase 60 (Fig. 6 A-6B) then.Shown in Figure 1A, intermediate core 33 can be longer than external core 31,35.A plurality of modular cores have similar design and architectural feature, also are in the spirit and scope of the invention yet have dissimilar cores in same pillow 30.
In embodiments of the present invention, it is thick that intermediate core 33 is approximately the 16 inches long wide X3 inches of X11 inch, and in the external core 31,35 each all to be approximately the 8 inches long wide X3 inches of X11 inch thick.
Pillow is a pivotally attached, thus in a plurality of core 31,33,35 one can move and pivot around another.
The structure that corner plate is housed of three compartments by pillowcase 60 is provided with hinged, and compartment is of a size of and holds described a plurality of core 31,33,35 respectively.Pillowcase 60 allows cores to pivot relative to each other and rotate along hinged crease 39.

In " open and flat " shown in Figure 1A structure, the thickness of pillow 30 is to design at bowing the person of sleeping and the person of sleeping on one's back, because it allows user's head to place with angle nature, that benefit rest.In " folding " shown in Fig. 1 C structure, the increase thickness of pillow 30 makes the side person's of sleeping head be supported on suitable height, thus backbone arrange suitably, reduced spinal compression and increased sleeper's traveling comfort.Otherwise Figure 1B show from open and flat structure to folded structure conversion or according to pillow of the present invention with according to pillow assembly of the present invention.
In one embodiment, the thickness that is in the pillow 30 of the open and flat structure shown in Figure 1A is approximately 3 inches, length and is approximately 32 inches, and this length is near the width of single bed.In the folded structure shown in Fig. 1 C, the thickness of pillow 30 is approximately 6 inches, and length is approximately 16 inches.It will be apparent to one skilled in the art that and can change size of the present invention---comprise thickness and length, and it is in the spirit and scope of the invention still.
Fig. 2 A and Fig. 2 B show and have the close up view that big three-dimensional interconnection is opened the shape-memory material of chamber type structure.Pillow to open chamber type structure big more, air is easy more to be flow through, it is big more with the heat that the health of taking away produces, and has reduced sleeper's uncomfortable property thus and has kept local temperature lower.What open chamber type structure is permeability to windstream on the other hand.Opening chamber type structure can be artificial material or natural material.The example of artificial material includes but not limited to: non-weaving extrusion type nylon polymer is the form of fabric of the 3 D weaving of being made by regenerated fibers such as for example polyester.The example of natural material includes but not limited to: cotton perhaps presents its form of mixtures.The size of the filament that the flexibility of pillow 30 and rockiness can be extruded by control and the quantity of opening filament in the per unit volume of chamber type structure change.
Shape-memory material well known in the prior art open a plurality of cores 31,33,35 that chamber type structure can be used for pillow 30.Fig. 3 A-3D illustrates and has the embodiment that big three-dimensional is opened the multiple shape-memory material of chamber, and it is very suitable for described a plurality of core 31,33,35.The example of opening chamber type structure not repeating, ccasual three dimensional pattern more from the patterns of change of the regular repetition of plurality of fibers to plurality of fibers.Though the sparse property of opening chamber type structure of shape-memory material can change, but selects this structure, because this structure is allowed the heat that air free-flowing and then dissipation health produce.The porosity of opening chamber type structure of shape-memory material is beneficial to air flows.
Having this material of opening chamber type structure will allow the air free stream to cross the heat that pillow produces with the dissipation health.Have on all directions the big three-dimensional that all sees through windstream fully and open the material of chamber type structure and will allow wind circulation, be beneficial to gushing out and eliminating of a stagnant heat in the bag, waste gas, reduced uncomfortable property by gathering of heat of elimination thus.
But open the overlapping fiber that chamber type structure can comprise alternative.Open chamber type structure and can comprise a plurality of ridges, be beneficial to that each ridge of a plurality of chi chungs is crossed in airiness and by the zone between each ridge of a plurality of chi chungs.Open chamber type structure and can comprise that a plurality of passages are therefrom to guide windstream and windstream is guided out pillow 30.
The chamber type structure opened of the present invention provides the intensity that supports user's head weight, has reduced the spot pressure by producing with face joint, and has improved blood circulation.
Open chamber type structure and also support for example characteristics such as flame resistance, elasticity and absorptivity.The all material that uses in all cores, core retainer plate and pillowcase all can see through free-pouring air fully from it.
The big chamber type structure of opening of the core material of pillow 30 provides a plurality of passages, is used to make air to flow through and take away heat without restriction.High volume one surface area ratio by pillow has strengthened transfer of heat.Therefore, the natural law of heat and maskant transfer is followed in the mobile and motion of air.Warmer air rises, colder air descends.Heavier gas will be under the lighter gas.
Because its motion and flow and will no longer rely on any dynamo-electric auxiliary device, this exchange is that mourn in silence fully and very flexible, can destroy or lose efficacy without any thing, and will not need to maintain personnel or operation budget.
Because it opens chamber type structure, the present invention is dissipated heat that health produces to alleviate generally the discomfort that mutual action was caused by health and bedding system.Because the part of sleeper's health engages the contact surface of pillow 30, the heat that health produces is stored in the local environment of health and contact surface joint.Open chamber type structure a plurality of passages are provided, air therefrom flows through and takes away heat, has strengthened from contact surface by conduction, convection current and thermal-radiating transfer of heat by such chamber type structure of opening.
Over-all heat transfer conduction, convection current and thermal radiation and transmit.Transfer of heat is the function of temperature and hot-fluid.Temperature is a tolerance of obtainable heat energy size.Hot-fluid is that heat energy moves to the another location from a position.Heat always from high temp objects to the cryogenic object transmission.Do not having under the situation of thermal drop, will not have transfer of heat, and not have hot-fluid.According to the first law of thermodynamics, transfer of heat has changed the interior energy of high temp objects and cryogenic object, and the energy size that high temp objects loses (emitting) equals the energy size that cryogenic object obtains (reception).The application that the first law of thermodynamics is a conservation of energy theorem aspect hot.
In conduction, the heat only molecule disturbance by in material is transmitted, and on the material monolithic without any motion.When the heat energy of high-temperature zone flow to low-temperature space, the particle that energy is higher, speed is higher of heat gave its energy and its temperature that raises at internal disturbance and the colder particle that energy is lower, speed is lower of collision.In the present invention, some heat are also by dissipating along the conduction of chamber node.
In convection current, over-all heat transfer is the own Motion Transmission of air or water or other fluid quality for example.Fluid is removed from thermal source, takes away heat energy thereupon.When stationary fluid is heated, there is local volume expansion, be attended by the local corresponding decline of density.The pressure gradient that gravity causes causes the fluid buoyance lift that expands and moves, by the Motion Transmission heat of hot fluid.
Thermal radiation is with the transmission of electromagnetic wave form from the heat energy of warm surface dissipation.Thermal radiation need not propagation medium.Occur between the solid surface by thermal-radiating transfer of heat, even also be like this among vacuum.
Be present in indoor ambient air and free stream crossed the arbitrary face of the pillow that the periphery by pillow limits.The chamber type of opening of the present invention is configured to free-pouring air high volume-surface area ratio is provided, and has strengthened thus from the extraction of the heat of a plurality of cores 31,33,35 of pillow 30, and it is taken in the atmosphere.Some heats are also by dissipating along the conduction of chamber node.Eliminated the discomfort that temperature that the heat that produces because of health causes rises the sleeper is produced.
The modular construction of pillow 30 of the present invention and open chamber type structure the matrix of cleaning easily is provided when needed.Fig. 4 A, 4B and 4C show the module of pillow 30.These modules are made of one of a plurality of cores 31,33,35 in the insertion core retainer plate 50.Pillow 30 of the present invention has a plurality of modules.In the embodiment shown in Figure 1A-1C, pillow has three modules.Have one, two, four or more the pillow of multimode also be in the spirit and scope of the invention.The pillow module can immerse in the clean solution, carries out rinsing subsequently.Because it opens chamber type geometry, the pillow module will become dry fast.
By allowing windstream through opening chamber type structure, with shortage the pillow of the prior art of the permeability of windstream to be compared, pillow 30 and user's thereof local environment will more be rich in oxygen.Having useful application aspect the children of this concrete feature in overcoming baby carrier the sudden infant death syndrome (SIDS), drawn sudden infant death syndrome in theory because of autointoxication---the baby sucks the carbon dioxide of himself breathing out and produces.Lack air flows in its baby carrier and compare gas concentration lwevel than the big soluble CO of existence with oxygen-enriched air
2Be stuck near the situation that the baby is and its total amount becomes fatal gradually.This is under the prone position situation all the more so the baby, under this posture, and its facial pillow or crib sheet of contacting with nose.By more oxygen-abundant air space is provided, opens chamber type structure and can be used to prevent SIDS.The air of the chamber type structure of flowing through out will be taken away the carbon dioxide of exhalation and bring fresh oxygen-enriched air for the baby.
The elastic shape memory material that has constituted pillow 30 of the present invention will recover from its stress and strain after load is removed.In case receive the weight of user's head, the shape-memory material of pillow 30 of the present invention is not returned the power that is deformed into direct ratio with it.The shape-memory material of pillow 30 is lax under load, provides distribution of pressure simultaneously on user's head scope.The distribution of pressure has reduced spot pressure, has eliminated potential blood vessel and has been obstructed and has improved traveling comfort.After removing the weight load of head, shape-memory material makes pillow 30 recover it and is not subjected to the structure of load at first.
In embodiments of the present invention, shape-memory material is viscoelastic.Visco-elastic material presents adhesion properties and elastic property.In cohesive material, all energy dissipations that apply are heat.In elastomeric material, all energy that apply are stored in the material.
In embodiments of the present invention, shape-memory material is the material (for example, loofahs material or similar structures) that has out the natural generation of chamber type structure.In another embodiment of the present invention, shape-memory material is a fungi-proof.The growth of pathogenic microorganisms can be eliminated or suppress to anti-biotic material.In embodiments of the present invention, shape-memory material is a biocompatibility.
As mentioned above, because the hard degree of the density of opening chamber type structure of pillow 30 of the present invention and type control pillow, by it is changed, the rockiness of pillow and flexibility can change.Though the hard degree of pillow 30 of the present invention can change, the large scale of opening chamber type structure will remain unchanged, to keep air freedom and the heat that easily flows through and then take away the health generation.
