Description

Shock reduction member {Shock-absorbing member}

TECHNICAL FIELD The present invention relates to an impact reducing member, and more particularly, to an impact reducing member which is applied mainly to an article to be used in contact with a human being so as to effectively alleviate a shock that may be applied to the body when using the article.

In general, ① rugs such as mats, mattresses and cushions ② pillows ③ protective equipment ④ shoe insoles, soles ⑤ sofas, seats such as chairs or saddles, etc. Articles that can be subject to various impacts, such as pressure, have a shock reduction member that provides softness or mitigates the impact a user will receive.

Shock absorbing materials that have been used for a long time include cushioning materials made by agglomeration or compacting of natural materials such as cotton, straw and natural rubber.In recent years, as technology is advanced, rather than using springs, original or foamed soft synthetic resins. The trend is to use synthetic rubbers or airbags. However, these impact reducing members were less efficient or limited in use as follows.

-Natural materials, such as cotton, straw, and natural rubber, generally do not expect high buffering effects. And most of them are relatively large in weight and relatively inefficient.

-Most of the springs are made of metal, so they are heavy and difficult to form at will.

-In the case of foamed flexible synthetic resins, foams of continuous foam are usually formed. In order to exhibit a practical level of buffering effect despite the low density according to the foam structure, the elastic modulus of the flexible synthetic resin material must be increased. However, this results in side effects that reduce the feel and shock absorbency of the foam. On the other hand, in the case of making a foam in the form of an independent bubble with a flexible synthetic resin, there is a limit to increase the elastic modulus of the material in the manufacturing process, so that a relatively too soft cushioning material is obtained, thereby exhibiting practical limitations of the member.

-Synthetic rubber is heavy when it is used in agglomerate state and its displacement due to compression is small. In many cases, it cannot function as a cushioning material. Of course, the same is true of natural rubber.

In addition, even in the case of the foamed synthetic rubber, the foam of the continuous foam is a problem in the foam structure, the foam of the independent foam is too soft due to the constraints in the manufacturing process, there is a limitation in the application purpose, and to supplement In the case where the synthetic rubber having high elastic modulus is mixed with the synthetic rubber, the compressive deformation occurs due to the repeated external force during the use of the member, resulting in a side effect of impairing the buffering ability. The same is true of natural rubber.

-Like air springs, air bags are difficult to manufacture at will, so their use is limited.

In summary, since the impact reduction members currently in widespread use are often inversely correlated with durability, cushioning capacity, and weight (apparent specific gravity), they do not show satisfactory effects according to the application. Bar, there is an urgent need for improvement.

An object of the present invention is to provide an impact reducing member that is economical and can more effectively alleviate an impact.

According to an embodiment of the present invention, a main body having a honeycomb structure formed of an elastic material and arranged such that at least a portion of the grooves are arranged in a row in a vertical direction, sealing each groove of the main body and entering and exiting air through the inlet of the groove An impact reduction member is provided that includes a closure means for sealing the.

Here, the groove of the main body may have a dome shape at the bottom thereof. In addition, the sealing means may include a sealing sheet bonded to the main body of the inlet of each groove of the main body is sealed.

According to an embodiment of the present invention, a honeycomb comprising a first body, a second body, and a sealing sheet, wherein the first body and the second body are made of a resilient material and the grooves are arranged so that the grooves are continuously arranged on one side thereof. The grooves have a comb structure and are disposed such that the grooves face each other, and the sealing sheet seals the grooves of the first and second bodies to block the entry and exit of air through the inlet of the grooves. Both surfaces are bonded to each other such that the openings of the grooves of the two main bodies are sealed to the first and the second main bodies, and the grooves of the first main body and the grooves of the second main body are provided with impact reducing members having different sizes. Can be.

In addition, according to an embodiment of the present invention, the elastic material and the grooves on one side of the both sides are arranged so as to be continuous horizontally and vertically, has a honeycomb structure and is provided with a plurality and close to each other and one side and the other side An impact reduction member comprising a main body bonded in a laminated state such that each groove between the seals is sealed, and sealing means for sealing each groove of an exposed groove of the plurality of main bodies to block the entry and exit of air through the inlet of the groove; May be provided.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the impact reducing member according to the present invention.

An impact reducing member according to a first embodiment of the present invention is shown in FIG. The impact reducing member of the first embodiment is mainly made by humans such as rugs (mats, mattresses, cushions), pillows, protective gears (such as helmets), insoles, soles or midsoles of shoes, and seats (such as sofas, chairs and saddles). It applies to articles that need to be used in direct or indirect contact, which mitigates the various impacts that a user may experience while using the articles.

As shown in Fig. 1, the impact reduction member of the first embodiment includes a main body 10 formed such that grooves 15 of a specific shape are continuously and horizontally continuous, and sutures sealing each groove 15 of the main body 10 are shown. Means;

The main body 10 is made of a flexible and stretchable material. As a material having such properties, a rubber (natural rubber, synthetic rubber) or a flexible synthetic resin belonging to a high molecular compound (polymer) is used. Flexible synthetic resins suitable for use as the material of the main body 10 include polyvinyl chloride, polystyrene, polyethylene, polyethylene-co-vinyl acetate, polyurethane (polyurethane), polypropylene, and the like.

The main body 10 may not be made of any one of rubber and soft synthetic resin. That is, depending on the implementation conditions, two or more different kinds of rubbers may be mixed or a mixture of two or more different kinds of soft synthetic resins may be formed, respectively, a mixture of at least one kind of rubber and soft synthetic resins. However, it is preferable to use natural rubber or synthetic rubber mainly because it is advantageous in terms of elasticity and compression set resistance.

The impact reducing member of the first embodiment is formed into an outline suitable for the purpose of the article to which it is applied.

According to this, although the shape is not specifically determined, the main body 10 was formed in the flat rectangular parallelepiped shape as an example here. In addition, the groove 15 may be formed so as to cover only a part of the main body 10, or may be formed so as to cover the whole of the main body 10, but here, one surface of the main body 10 is provided. It was formed so as to cover the whole (top view in Figure 1).

The grooves 15 arranged vertically and horizontally allow the body 10 to have a honeycomb structure. Each groove 15 providing the honeycomb structure may be circular (including elliptical) or polygonal in cross section, here formed as a regular hexagon. When formed in a regular hexagon as shown in FIG. 1, the grooves 15 may be arranged at the same interval when all the sizes of the grooves 15 are the same. Of course, this may also be formed in the shape of a square or an equilateral triangle instead, but the reason why it is a regular hexagon is that it provides a lower density and stable structure.

Each groove 15 can be changed according to the article to be applied such that its depth may be all or partly different, but here, all grooves are formed to be the same.

Each groove 15 also has its bottom 16 in a dome shape, which reinforces the mechanical properties of the honeycomb structure.

The sealing means is provided in each groove 15 to prevent air, which is intended to be filled in each groove 15, from flowing out of the groove 15 through the inlet of the groove 15 or vice versa. The inlet of) allows each groove 15 to act as an independent air cell. The sealing means includes a sealing sheet 22 which is adhered to the groove 15 forming surface of the main body 10 (upper surface in FIG. 1) so as to be in close contact with the entire surface of the body 10 and blocks the inlet of each groove 15. .

In the case of the sealing sheet 22, it is made of an elastic material similarly to the main body 10. Preferably, natural rubber or synthetic rubber is used as a material having such properties. Of course, harder materials may be used depending on the implementation conditions.

Bonding of the sealing sheet 22 is carried out by the method of fusion | melting and an adhesive agent. Adhesives that can be used to bond the sealing sheet 22 include natural rubber, styrene butadiene, synthetic rubber such as isoprene-isobutylene, chloroprene, and hot melt. melt), polyvinyl chloride, and the like.

As described above, the impact reducing member of the first embodiment, in which each groove 15 of the main body 10 is sealed by the sealing sheet 22 and serves as an independent air cell, is deformed due to the elasticity of the material when the impact is applied. At the same time, the restoring force appears and at the same time, the air inside the groove 15 is compressed and the repulsive force appears at the same time. In this process, the neighboring grooves 15 disperse the impact, so the elasticity and the circular recovery force are very excellent. Not only is it large, but it is not easily squeezed even after repeated impacts, so that permanent deformation is not easily generated. In addition, the impact reducing member of the first embodiment also has the advantage that the thermal insulation effect is excellent due to the heat insulating action of the air trapped in the groove 15.

On the other hand, the impact reduction member of the first embodiment is a cushioning effect is determined by the elastic properties of the material, in general, the elastic material is a rubber or synthetic resin raw materials, such as reinforcing agents, softening agents, fillers, etc. It is made by adding according to a predetermined ratio, and as a result, when the material is tensioned, the elongation when reaching the yield point is required to be at least 50% or more, more preferably 100% or more.

Here, the material refers to a polymer compound that has been crosslinked or compounded under conditions that do not include a composite material reinforcement such as short fibers, and the properties such as hardness and elastic modulus of the material may be used for the article to be applied and the site of the article. Of course, it must be properly designed according to.

2A to 2D show a mattress, a pillow, a shoe insole, and a chair to which the impact reduction member of the first embodiment is applied, respectively.

The mattress includes at least one cushion member formed in a cuboid shape having a size that one or more persons can lie down, and a cover covered with a cushion composed of the cushion member, as shown in FIG. Can be used as a cushion member of this mattress. (The thin dashed line indicates a cover.) The impact reducing member of the example can be applied to other types of rugs, such as mats, cushions, etc., by changing the shape, such as thickness and size.

As shown in Fig. 2B, the impact reducing member of the first embodiment can be used as a pillow as it is formed in the shape of a pillow. You can, of course, cover a pillowcase if you need it (the thin line is a pillowcase). Alternatively, you can attach a detachable finish made of soft, soft fibers instead of the pillowcase.

As illustrated in FIG. 2C, the impact reducing member of the first embodiment may be used as the insole of a shoe as it is formed in the shape of an insole close to the bottom of the shoe such as shoes and sneakers. Of course, if necessary, a finishing sheet may be attached to the upper surface (the surface on which the sole touches the foot) to improve the feel.

As such, when applied to shoes, the impact reducing member of the first embodiment may be applied to constitute only a part of the insole, since it does not necessarily have to be the entire insole. That is, for example, it may be added only to a portion where a relatively heavy weight of the user is carried, such as the back portion of the insole (where the heel touches). Alternatively, a plurality of layers may be laminated to have a multilayer structure. Alternatively, in this way, only a portion where the weight of the user is carried may have a multilayer structure.

Here, only the use of the impact reduction member of the first embodiment as an insole of the shoe has been described. Alternatively, the impact reduction member of the first embodiment may be applied to constitute the bottom of the upper, and the sole (including the midsole) may be used. It can also be adapted to configure.

The chair has a seat portion and a back portion, and as shown in Fig. 2D, the impact reducing member of the first embodiment can be used as a cushion provided in the back portion to provide softness. Of course, the impact reducing member of this first embodiment can be applied not only to the back portion but also to the seat portion to be used as a cushion.

On the other hand, the impact reduction member of the first embodiment applied as described above may provide the user with an anti-slip or acupressure effect by having the surface has an uneven structure, if necessary, nano silver (nano silver), etc. in the material It is also possible to have antimicrobial properties by adding an antimicrobial agent.

Next, other embodiments that are configured similarly to the impact reducing member of the first embodiment will be described. In this case, another embodiment will be described based on other parts as compared with the impact reducing member of the first embodiment.

3 is a perspective view showing an impact reducing member according to a second embodiment of the present invention, as shown here, the impact reducing member of the second embodiment has other configurations and its comparison with that of the first embodiment; The working effects are the same for both of the same, but having two main bodies 10 and 10A, except that the two grooves 15 and 15A are sealed by one sealing sheet 22.

3, since the main body 10 (hereinafter referred to as the upper main body) and the sealing sheet 22 located above are the same as those of the first embodiment, detailed description thereof will be omitted.

3, the main body 10A (hereinafter referred to as a lower main body) located at the lower side is different from the upper main body 10 only in that the size of the groove 15A is different, and each groove in the sealing sheet 22 is different. 15A is sealed and adhere | attached so that the entrance of air through the inlet of this groove 15A may be blocked. That is, the lower main body 10A is disposed so that the upper main body 10 and the grooves 15A and 15 face each other, and the sealing sheet 22 is interposed between the upper and lower main bodies 10 and 10A. Both sides are bonded to the upper and lower bodies 10 and 10A so that the inlets of the grooves 15 and 15A are sealed.

As described above, the impact reducing member of the second embodiment has a multi-layer honeycomb structure by the two main bodies 10 and 10A, and thus has a superior feel and elasticity than a single layer, and the grooves of the two main bodies 10 and 10A. (15) (15A) Different sizes provide different touch and elasticity depending on which one is used. For example, when the impact reducing member of the second embodiment is applied to a pillow, when it is turned upside down during use, the other side is provided with a different feel and elasticity than before.

4 is a perspective view showing an impact reducing member according to a third embodiment of the present invention. As shown here, the impact reducing member of the third embodiment may have other configurations and its comparison with that of the second embodiment. The effects are all the same, except that in the case of the upper body 10, the groove 15 is formed on one side of both sides, and further includes one or more laminated body 10B.

Here, the laminated main body 10B is the same as the upper or lower main body 10 and 10A, and the groove 15B forming surface thereof is the other side of the upper surface of the upper main body 10 (the surface where the groove is not formed). ), The grooves 15B are laminated so as to be sealed and adhered in this stacked state. Of course, the groove 15B of the laminated body 10B may be different in size from that of the upper or lower body 10 (10A). In addition, the laminated main body 10B may be formed on the other side of both sides of the lower main body 10A by forming a groove 15A on one side of both sides of the lower main body 10A instead of the upper main body 10. In some cases, the upper and lower bodies 10 and 10A may be stacked. When the laminated body 10B is stacked only on any one of the upper and lower main bodies 10 and 10A, the other one of the upper and lower main bodies 10 and 10A may be omitted.

According to this laminated body 10B, the impact reduction member of 3rd Example can change the thickness without providing the sealing sheet 22 separately.

FIG. 5 is a perspective view showing an impact reducing member according to a fourth embodiment of the present invention, and as shown here, the impact reducing member of the fourth embodiment may have other configurations and its comparison with that of the first embodiment. The effects are all the same, except that the main body 10 is provided without the sealing sheet 22.

The two main bodies 10 here are the same as those of the first embodiment and are formed such that the grooves 15 coincide with each other when the grooves 15 face each other, and thus the grooves 15 coincide with each other. Is bonded. According to this, one of the two main bodies 10 also serves as a sealing means.

6 is a perspective view showing an impact reducing member according to a fifth embodiment of the present invention, as shown here, the impact reducing member of the fifth embodiment has all other configurations compared with that of the first embodiment; The same thing is different, except that the main body 10C is composed of the honeycomb structure 12 and the shield 13, which will be described below.

The honeycomb structure 12 is provided so that the holes penetrating at least a portion thereof vertically and horizontally continuously, and the shield 13 is made of the honeycomb structure 12 by an adhesive or the like so that one of both ends of each hole is sealed. Is bonded to.

Here, the hole of the honeycomb structure 12 whose one end is blocked by the shield 13 becomes the groove 15C of the main body 10C, and the groove 15C has its inlet as that of the first embodiment. Likewise sealed by the sealing sheet 22 serves as an independent air cell each.

Thus, the impact reduction member of the fifth embodiment configured by dividing the main body 10C into the honeycomb structure 12 and the shield 13 has one or more additional honeycomb structures 12 as shown by the double-dotted line. It may also be bonded to be laminated on both sides.

Meanwhile, although the bottom of the groove 15C is not shown to be formed in a dome shape in the drawings, the shield 13 may be recessed in a hemispherical shape with each part facing the hole of the honeycomb structure 12. Thus, each groove 15C may have a dome shape at its bottom.

Also in the case of the second to fourth embodiments, the main body may be divided into a honeycomb structure and a shield.

The present invention has been described above, but the present invention is not limited to the embodiments disclosed in the specification and the accompanying drawings, and may be variously modified by those skilled in the art without departing from the technical spirit of the present invention.

For example, in the above description, the grooves are concentrated on only one side of the main body, but the grooves may be formed in any part as long as the grooves can be sealed by sealing means. Therefore, the grooves may be formed on both sides of the main body, respectively, and the grooves on both sides may be different in size from each other, and this configuration can expect an effect similar to that of the second embodiment.

In addition, in the above description, the sealing sheet is only bonded to the main body, but the sealing sheet may have protrusions that are fitted into the grooves of the main body when the sealing sheet is bonded to the main body. The protrusion improves the bonding force between the main body and the sealing sheet, and may be bonded while being inserted into the groove to improve the bonding force.

In addition, the present invention may be applied or partially used instead of a suture stopper which is fitted into each of the grooves and bonded in such a fitted state to seal the inlet of the groove as sealing means.
