Description

High-frequency sealing of the elastic layer to improve the supporting effect

The invention relates to a cushion body which performs high-frequency sealing on the elastic layer to improve the supporting effect, in particular, the high-frequency technique is used to weld at least two elastic layer two corresponding side edges into one body, so that the elastic layer can be warped by elasticity. A cushion body that produces different bulkiness and thus achieves a better support effect.

According to the relationship between modern people because of work or living habits, they often stay in the same position for a long time. For example, office workers sit at their desks for a long time, silver-haired people sit on sofas for a long time, and teenagers spend a long time in front of game consoles. Over time, not only It is prone to fatigue and is more likely to unwittingly deviate from the correct posture, causing problems in muscles, spine or joints. Therefore, some industry players have identified this demand and designed a variety of "seat cushions" that can help people maintain their sitting posture, or "headrests", "neck pillows" and "mattresses" that allow people to relax in the correct posture. Various cushion products such as "chair cushion" and "back cushion".

However, most of the various cushion products are made of foamed materials. Therefore, once used for a long time, the foamed material will gradually lose its supporting effect due to elastic fatigue. In addition, although the foaming material can Softly hold the user's head, neck, waist or back, but it does not provide a firm support force to ensure the correct posture of the user, that is, the conventional cushion product can not effectively take into account Comfort and "support" are two appeals. Although in the "mattress" product, the "independent tube spring" design can solve the problem that the general spring mattress is easy to partially collapse and deform. However, the "independent tube spring" is limited by its structure and cannot be applied. In various sizes of headrests, neck pillows, seat cushions and other products, and its production process and production costs are also high, there are many limitations in the application of difficult to implement.

In addition, the inventor of the present invention has designed a product "a pillow that can assist the head to relax" and has applied for a Taiwan invention patent (application number 102147775), which is advantageous for the product. With its unique configuration, the principle of "cranial sacral therapy" is used to abut the corresponding part of the user's skull, thereby promoting the flow of cerebrospinal fluid in the user's head. However, the inventors have found that if only the general foaming material is used to make a "pillow that can assist the head to relax", once the foamed material loses its elasticity, the effect will be greatly reduced, so it is necessary to improve the material. To enhance the efficacy and durability of the "Pedients that can help the head relax."

In summary, at present, various cushion products are limited by the characteristics of the material, and cannot provide a comfortable touch under the premise of ensuring the stability and strength of the support. Therefore, how to materialize the cushion product Or the structure is improved to take into account its "comfort" and "support", and at the same time, it can be applied to the product of "the pillow that can assist the head to relax" developed by the inventor in the past. Important issues to solve.

In view of the fact that the conventional cushion products cannot balance the effects of "comfort" and "support", the inventors have, after years of research and development experience, finally designed a pair of elastic layers of the present invention. The high-frequency sealing to improve the supporting effect of the cushion body can effectively improve many shortcomings of the conventional technology.

An object of the present invention is to provide a cushion body for high-frequency sealing of an elastic layer to improve a supporting effect, comprising two first elastic layers, at least two first sealing portions and a jacket layer; the first elastic layers respectively The utility model is composed of a plurality of elastic yarns which are twisted and twisted, and the elastic yarns are made of plastic materials (such as PE, EVA, PP, PVC, PET or a mixture thereof); the first sealing parts are in the first The two corresponding side edges of the elastic layer are respectively formed by welding with a high-frequency technique, and after the elastic wires of the corresponding side edges of the first elastic layers are welded and fixed, the elastic wires of other parts of the first elastic layer can be Warping outward, so that the thickness of the corresponding side edge of the first elastic layer can be smaller than the thickness of other portions; an accommodating space is formed in the outer layer, and the configuration of the accommodating space and the first elasticity The layers are matched to fix the first elastic layer in the accommodating space to form the pad body. Thus, by the design of the first sealing portions, the portions of the first elastic layer that are away from the first sealing portions are relatively bulky, and can softly support the user's head, back or waist. The portions of the first elastic layer adjacent to the first sealing portions are relatively dense, and the portions of the first elastic layer that are away from the first sealing portions are prevented from being excessively deformed or collapsed after bearing. .

Another object of the present invention is that the pad body further includes two second elastic layers, each of the second elastic layers also composed of a plurality of twisted and wound elastic wires, and is positioned between the first elastic layers, so that One of the first elastic layers corresponds to the side through which the second elastic layers abut each other. Accordingly, the elastic layer can be designed to have different hardnesses according to product requirements, so as to produce better support effects.

For the sake of review, the reviewer can have a further understanding and understanding of the application mode, structural features and purposes of the present invention. The embodiments are described in conjunction with the drawings, which are described in detail as follows:

The present invention is a pad body for high-frequency sealing of the elastic layer to improve the supporting effect. Referring to FIG. 1 , a first preferred embodiment of the present invention, the pad body 1 includes two first elastic layers 11 , At least two first sealing portions 110 and a jacket layer 12, wherein the first elastic layers 11 are respectively composed of a plurality of twisted and wound elastic wires P, and have toughness and elasticity, and the elasticity The material of the wire P can be PE (polyethylene), EVA (Ethylene vinyl acetate), PP (polypropylene, Polypropylene), PVC (polyvinyl chloride), PET (ethylene phthalate). A plastic material such as a polyester terephthalate or a mixture of the foregoing plastic materials, and each of the first elastic layers 11 may be made of different materials.

When the first elastic layer 11 is formed, the configuration is a fluffy plate having a uniform thickness (only a schematic cross-sectional view in FIG. 1), and one of the first elastic layers 11 can mutually correspond to each other. In the high-frequency technique, the two corresponding side edges of the first elastic layer 11 are welded, so that the elastic wires P in the corresponding side edges of the first elastic layers 11 can be fixed into one body, thereby forming the In the first joint portion 110, since the elastic filaments P have a certain elasticity and toughness, the first elastic layer 11 is welded after the elastic filaments P of the corresponding side edges of the first elastic layers 11 are welded and fixed. Because the elastic yarn P of other parts is stretched and compressed toward both sides, it can be warped outwards, and appears to be relatively bulky, so that the thickness of the corresponding side edges of the first elastic layers 11 can be smaller than the thickness of other parts. .

The jacket layer 12 can be a cloth sleeve or an elastic mesh layer, and an accommodation space 120 is formed therein, and the configuration of the accommodation space 120 is matched with the first elastic layers 11 so as to be able to The pad body 1 is formed by the first elastic layer 11 being fixed in the accommodating space 120. The size of the accommodating space 120 can be designed according to the requirements of the manufacturer. For example, the width of the accommodating space 120 can be slightly smaller than the thickness of the first elastic layer 11, so that the first elastic layer 11 must be slightly compressed as a whole. The width of the accommodating space 120 may be slightly larger than the thickness of the first elastic layer 11 only to maintain the smoothness of the surface of the pad body 1.

Thus, the gap between the elastic wires P of the first elastic layer 11 adjacent to the first sealing portions 110 will be smaller than the distance between the first elastic layers 11 by the design of the first sealing portions 110. The gap between the elastic wires P of the first first sealing portion 110, that is, the portion of the first elastic layer 11 away from the first sealing portions 110 will be relatively bulky (low density), Softly supporting the head, the back or the waist of the user, and the portions of the first elastic layer 11 adjacent to the first sealing portions 110 are denser (higher density), and the first elasticity can be avoided. The portion of the layer 11 remote from the first sealing portions 110 is excessively deformed or collapsed after the load bearing, whereby the optimum supporting effect can be combined by the change in the softness of the cushion body 1.

It is to be noted that the first sealing portion 110 shown in FIG. 1 is only a schematic view. After the elastic wire P is sealed by high-frequency technology, the first sealing portion 110 may have an irregular shape. The first elastic layer 11 can be designed to have different densities and supports according to design requirements, for example, selecting elastic wires P of different wire diameters, changing the original gap or distortion between the elastic wires P, Use different materials, different thicknesses, etc. As far as the material is concerned, according to the test results of the inventors, PE and EVA have the best effect, but the cost of PE is higher, while among other materials, PVC is hard and PET is soft.

In other embodiments of the present invention, more elastic layers can be combined to form a cushion body, as shown in FIGS. 2A-2D, which are four main embodiments of the present invention (the outer layer is omitted in the drawings) 2A is a second preferred embodiment of the present invention. The pad body 2 includes two second elastic layers B1 and B2 in addition to the two first elastic layers A1 and A2. The elastic layers A1. A2, B1, and B2 are each composed of a twisted and entangled elastic yarn, and two corresponding side edges of the first elastic layers A1 and A2 can be sealed to form a first sealing portion X; the second elastic layers B1 and B2 Positioned between the first elastic layers A1, A2 such that one of the first elastic layers A1, A2 can be abutted against each other through the second elastic layers B1, B2; the second elastic layer The two corresponding side edges of B1 and B2 can also be welded by a high-frequency technique to form two second sealing portions Y, so that the thickness of the corresponding side edges of the second elastic layers B1 and B2 can be smaller than the thickness of other portions.

2B is a third preferred embodiment of the present invention, but the two corresponding side edges of the first elastic layer A1, A2 and the second elastic layer B1, B2 are simultaneously welded together by a high-frequency sealing technique, that is, The second side edges of the second elastic layers B1 and B2 can pass through the high-frequency technique, and the first sealing portions X and the second B are combined with the corresponding side edges of the first elastic layers A1 and A2. 2B is a view in which the first sealing portion X and the second sealing portion in the second drawing are welded together, and the structure shown in FIG. 2B is compared with the method shown in FIG. 2A. At the same time, four layers of elastic layers A1, A2, B1, and B2 are sealed, so the change in elasticity is more obvious, that is, the density of the two sides is higher.

2C is a fourth preferred embodiment of the present invention, the structure is such that one side edge of the second elastic layers B1, B2 is transmitted through a high-frequency technique, and a side edge corresponding to one of the first elastic layers A1, A2 The first sealing portion X is sealed together, and the other side edge of the second elastic layers B1 and B2 can be separately sealed into a second sealing portion Y by a high-frequency technique, and accordingly, the cushion body 2 is Two The elasticity and softness of the corresponding side edges will be different.

2D is a fifth preferred embodiment of the present invention, and one side edge of the second elastic layers B1 and B2 is also passed through a high-frequency technique and is sealed together with a side edge corresponding to one of the first elastic layers A1 and A2. The first sealing portion X is synthesized, and the other side edges of the second elastic layers B1 and B2 are kept bulky and are not sealed by high-frequency technology, so that a special tactile sensation of external hard and soft can be formed.

In Figures 2A to 2D, four applicable sealing methods are respectively illustrated. The manufacturer can select the corresponding sealing method according to the characteristics of the product to be produced, so as to produce rich changes of soft and hard, as shown in Fig. 3, The method of applying the cushion of this case to the pillow is described by the inventor's "Pedient for assisting the head to relax". The pillow 3 includes a supporting body 31, two contact portions 32 and an abutting portion 33. The top of the supporting body 31 is for supporting a neck of a user lying on the back, and a recess 310 is recessed at the bottom. A recessed portion 311 is respectively disposed on the support body 31 adjacent to the two corresponding ends and corresponding to the tibia of the user's head; one end of the contact portions 32 respectively engages with the corresponding ends of the support body 31, and Maintaining a first predetermined spacing from each other, the other ends of the contact portions 32 extending away from the support body 31 and maintaining a second predetermined spacing from each other, the second predetermined spacing being less than the first predetermined spacing, So that the configuration of the contact portions 32 can correspond to the two parietal bones of the user's head, respectively.

The abutting portion 33 extends from one side of the support body 31 and is located between the contact portions 32 to respectively abut the support body on the neck and the head of the user. In the case of 31 and the contact portions 32, the tibia of the user's head can be held not only at the position corresponding to the recessed portions 311, but also the support body 31 can be oriented toward the weight of the user's neck. The groove 310 is bent downward and deformed, so that the two corresponding ends of the support body 31 are bent upward and deformed, so that the other end of the contact portion 32 can be tilted toward the top bone of the user's head to support the two parietal bones. At the same time, the free end of the abutment portion 33 can be tilted toward the occiput of the user's head and abut against the occiput.

In order to improve the supporting effect of the pillow 3 on the user's skull, one side of the supporting body 31, the other side and the outer edge of the abutting portion 33 may be designed as a reinforcing portion 34 (the position is indicated in FIG. 3) And the range, that is, the first elastic layer A1, A2 and the two corresponding side edges of the second elastic layers B1, B2 are collectively sealed into the first sealing portion by the sealing method shown in the above FIG. 2B X, to have a harder support; and the outer edge of the contact portion 32 (ie, the pillow in Figure 3) The first elastic layer and the second elastic layer (such as the sealing method shown in FIG. 2A) may be respectively sealed by a high-frequency technique to form a first sealing portion and a second sealing portion. In other words, in terms of softness, "one side of the support body 31, the other side, and the outer edge of the abutting portion 33" are larger than "the outer edge of the contact portion 32", "the contact portions" The outer edge of 32 has a hardness greater than the rest of the pillow 3. According to the above, the wearer can also coat the degree of tightness of the pillow 3 with the outer layer, and change the supportability of the pillow 3 and the warping effect after the force.

In addition, as shown in Figures 2A to 2D, the softness between the elastic layers A1, A2, B1, and B2 can be freely adjusted without being consistent, that is, the first elastic layers A1, A2 (or The second elastic layers B1, B2) may be soft and hard, and the first elastic layers A1, A2 and the second elastic layers B1, B2 may have different hardnesses, respectively. The factors affecting the softness include the material of the elastic filament P and the wire diameter (the diameter of the elastic filament P is about 0.05 to 1 mm, and preferably 0.05 to 0.5 mm), the spacing, and the distortion. The degree of thickness or the thickness of the entire elastic layer is understood by those skilled in the relevant art, and the manner of changing the "pitch" and "distortion degree" is as follows.

Please refer to Fig. 4, which is a schematic diagram of the elastic layer. First, the plastic material P' (mostly solid granular) is placed in a heating bath 41 to be melted by heat, crucible, pushed and melted. The plastic material P' enables the molten plastic material P' to pass through a plurality of small holes 410 at the bottom of the heating tank 41 to form the elastic filament P. The elastic filament P is gradually entangled and twisted with cooling, and finally is arranged through a guiding passage 42 (which may be a channel of the Teflon inner wall or a passage formed between the plurality of rollers) It is formed into a fluffy plate shape and formed by water cooling.

According to the foregoing process, the size or spacing of the holes 410 can be changed to change the "wire diameter" and "pitch" of the elastic wires. Further, the operator can also use a fan 43 to increase the air convection around the elastic wires P. Thus, You can change the "degree of distortion" (the faster the cooling, the more obvious the distortion). Alternatively, the operator can design a collecting wall 421 at the top end of the guiding passage 42, so that the elastic wires P on both sides of the outermost edge will be guided by the collecting wall 421 to gather toward the middle.

As shown in Figures 4 and 5, Figure 5 shows an elastic layer 5 (which can be used as the first elastic layer or the second elastic layer) after the elastic yarn P is guided by the folding wall 421. During the manufacturing process, the elastic filament P is gathered toward the center, so that the two high-density portions 51 can be formed in the elastic layer 5 adjacent to the two corresponding side surfaces (ie, the top surface and the bottom surface shown in FIG. 5). A low density portion 52. Similarly, the operator can design the gathering wall 421 only on one side of the guiding channel 42, so that the elastic layer 5 will only have a corresponding side adjacent to it (or at least one of the outer sides of the elastic layer 5). The portion having the high density portion 51.

Moreover, the main object of the present invention is to seal the multilayer elastic layer by high-frequency technology to produce a difference in elasticity and hardness, and in actual application, if the manufacturer has added the above-mentioned "high-density portion" in a single elastic layer. The structural features of 51" are that before stacking and affixing multiple layers of elastic layers, the manufacturer can further high-frequency sealing the "single layer" elastic layer to enhance its supporting effect, as shown in Figure 6 ( In order to avoid the complexity of the drawing, the high-density part is not drawn in the figure. When a first elastic layer 6 is cooled and formed, the manufacturer can use the high-frequency technique to seal the two corresponding sides (ie, the top of the drawing shown in Fig. 6). a corresponding portion on the surface and the bottom surface to form a plurality of third sealing portions 61, and the third sealing portions 61 can form a plurality of sealing lines on the two corresponding sides of the first elastic layer 6, please Referring to Figures 6, 7A and 7B, the sealing lines 71, 72 can be formed into a diamond shape or a wave shape (may also be square, round, etc.), and after the formation of the sealing lines 71, 72, the manufacturer begins. Laying two layers of the first elastic layer 6 against each other and performing the corresponding side edges thereof Sealing cycle, the first sealing portion 70 is formed, similarly, lines 71, 72, such sealing can be designed on the second elastomeric layer.

Referring to FIG. 8 , a partial enlarged view of a pad body 8 includes two first elastic layers 81 , 82 and a plurality of third sealing portions 83 , wherein the first elastic layers 81 . The left and right ends of the 82 can be naturally integrated through the first sealing portion (as shown in FIGS. 7A and 7B). However, in FIG. 8, the influence of the third sealing portion 83 is emphasized in a microscopic manner. Therefore, the first seal was not drawn, and the first seal was first. As shown in FIG. 8, in the present embodiment, the third sealing portions 83 on the first elastic layers 81, 82 of the different layers are mutually staggered (in the case of FIG. 7A as an example, that is, two layers of first elasticity) The sealing lines 71 of the layers 6 are offset from one another, whereby a user 80 (which may be the head, waist, hips or back) rests on the pad body 8, which produces at least the following three effects:

(1) Covering the leaning portion: Since the cushion body 8 of the present invention has good elasticity, the central portion of the cushion body 8 will be warped upwards after being loaded, thereby increasing contact with the user 80. The area prevents the user's head, neck, buttocks or back from sliding on the pad body 8, thereby forming an incorrect posture.

(2) Stable supporting effect: as shown in Fig. 8, after the elastic filaments P on the first elastic layers 81, 82 are partially welded together (i.e., the third sealing portion 83 is formed), the first The surface of an elastic layer 81, 82 will be wavy (ie, the third sealing portion 83 will be recessed), and the portion touched by the user is the relatively fluffy portion of the first elastic layer 81, 82. Therefore, the cushion body 8 can produce an effect like a "independent cylinder spring", and the bulk F of the user 80 can be uniformly received by the fluffed portions, and the deformation in the up and down direction is generated due to the third sealing portion 83. The first sealing portions (not shown) at both ends of the first elastic layers 81 and 82 are denser and can be held at a fixed position. Therefore, it is possible to ensure that the fluffed portions are not deformed by left and right sway.

(3) Structural strength of the cushion body 8: since the third sealing portions 83 on the first elastic layers 81, 82 of the different layers are mutually shifted, that is, the distribution of the softness and hardness on the first elastic layers 81, 82 According to the difference, the supporting effect between the first elastic layers 81 and 82 can be complemented, and the weight F to be uniformly transmitted to the upper, lower, left and right directions can not only improve the stability of the support, but also The durability of the cushion body 8 can be extended.

The high-density portion 51 shown in the fifth embodiment can also be combined with different support effects depending on the installation position. Referring to FIG. 9, a schematic view of the first preferred embodiment of the present invention is provided for convenience. The relative position of each part will be described. The first elastic layer 11' has an upper layer portion 111' and a lower layer portion 112'. The other elastic layer 11' has an upper layer portion 111' and a lower layer portion 112'. The first elastic layer 12' also has an upper layer portion 121' and a lower layer portion 122'. The manufacturer can design a high-density portion on each of the first elastic layers 11', 12' according to the actual needs of the product (such as the fifth (1) Four-layer reinforcement: When the upper layer portions 111', 121' and the lower layer portions 112', 122' are all passed through the process method shown in Fig. 4 to form a high-density portion, the pad is at this time. The body has the highest overall hardness, has the strongest supporting force, is not easy to be compressed, has the smallest deformation, and can effectively fix the ride or abutment of the user; (2) Three-layer reinforcement: when the first elastic layer 11', In 12', the upper layer portions 111', 121' and the lower layer portion 122' are formed with a high density portion, but the lower layer portion 112' is not formed high. At the time of the degree, the first elastic layer 11' is in a state of "upper and lower soft", so the overall hardness is lower than that of the "four-layer reinforcement"; and if the "three-layer reinforcement" is changed to the upper layer Portion 121', lower layer portion 112', 122' has a high density portion, and the upper portion 111' has a general density, so that the overall hardness can be slightly lowered; (3) double layer strengthening: that is, only two of the first elastic layers 11', 12' The portion is provided with a high-density portion, and the overall hardness is softer than the "three-layer reinforcement". According to the inventor's practical experience, if the high-density portion is provided in the upper layer portion 111' and the lower layer portion 122', the entire The pad body is in an "outer hard and soft" state, taking into account the elasticity and the supporting force; and if the high-density portion is provided in the lower layer portions 112', 122', since the two first elastic layers 11', 12' are The structure of "soft and hard" makes it feel softer and has a distinctly deformed feel.

Referring to FIG. 10, the cushion body of the present invention is formed as a cushion of a seat, wherein the upper and middle sections of the central axis of the cushion body 9 are provided with a joint portion 91, 92. (In particular, in FIG. 10, the position of the sealing portions 91, 92 is indicated in a schematic manner, and the actual sealing manner can be referred to the description of the first or 2B and the corresponding paragraphs), and Between the sealing portions 91, 92, that is, the portion of the pad body 9 adjacent to the top portion, a slit 90 is formed in the longitudinal direction (for example, through a cutting or punching tool, and is formed on the pad body 9), according to which Since the partition 90 can form the upper half of the cushion body 9 into the left and right regions, and the sealing portions 91 and 92 can bulge the middle portion of the two regions, the cushion can be further raised. The effect of the body 9 on the upper body of the user, for example, when the pilot of the aircraft is driving, if the body is to be tilted and turned, it is often necessary to use the center of gravity of the whole body for control (especially the fighter driver is more obvious), and generally The seat cushion is too loose, so the driver once leans That is, it is possible to produce a slip on the seat cushion; and the cushion body of the present invention is designed to pass through the partition 90, and when the driver is sitting, the left and right parts of the cushion body 9 can be supported by more obvious topography. The back part (such as the effect of "covering the leaning part"); and when the driver tilts the body to the left, since the left part of the pad body 9 is compressed, the right part thereof can generate warpage, and Still close to the driver's back, the driver can use the back reaction of the pad body 9 to help his body center of gravity pull back in a short time.

Referring to FIG. 11, a seat cushion 93 corresponding to the cushion of FIG. 10 is provided. A position of the seat cushion 93 corresponding to the driver's buttocks is provided with a recessed groove 930 adjacent to the recessed groove 930 and corresponding to driving. The portion of the thigh is provided with two sealing portions 931 (as shown in the above-mentioned first or second FIG. 2B, only the position thereof is shown), and the recessed groove 930 can cover the seat cushion 93. The driver's buttocks 931 prevent the driver's thigh from slipping.

Whether it is the slit 90 in FIG. 10 or the recessed groove 930 in FIG. 11 , the purpose is to recess a partition portion in an intermediate portion of the mat body (that is, the configuration of the partition portion may be a recessed groove , the opening, the slit), when the user rides or leans on the same, the part of the cushion body corresponding to the two sides of the partition can be warped upwards to support the user's riding or leaning position. Moreover, if the user changes the ride or leans against the center of gravity, the cushion body can also be deformed accordingly, so that the supporting effect is more obvious. Similarly, in the pillow 3 shown in FIG. 3, the operator can also be in the support body 31. A partition is recessed in the top surface. In addition, the pad can also be applied as a physical therapy posture adjustment chair.

The above description is only a few preferred embodiments of the present invention, but the technical features of the present invention are not limited thereto, and those skilled in the relevant art can easily think about changes after considering the technical content of the present invention. , should not depart from the scope of protection of the present invention.
