1 to 5, the shock absorbing pad elastic structure according to an embodiment of the present invention includes a cover member 10 and an elastic ball 20.

The cover member 10 may be a plate-type pad structure or a tube-type structure or an expansion joint pad structure in which the upper cover 11 and the lower cover 12 are bonded to form a hollow space.

That is, the plate-shaped pad structure is not only personal household goods or sports goods, but also lifesaving goods and vehicle tires, as shown in the attached FIGS. 1 to 8. In addition, it can be applied in various fields such as expansion joint members for construction, and more specifically, floor mats for noise absorption, cushions for acupressure and ventilation, insoles for sneakers, bicycle saddles, and shock absorbers applied to the inside of protective equipment (eg, helmets). It can be effectively applied to pads, protective patches attached to sportswear (eg, taekwondo, baseball, boxing, kendo, etc.) (eg, nangsim, chest, etc.) or protective patches attached to shoulder straps of bags.

For example, as shown in FIGS. 1 to 4, the cover member 10 may have a structure of a floor mat or a cushion for absorbing noise, and as shown in FIG. 6, the cover member 10 As it is manufactured as an insole structure for sneakers, a single pad with excellent ventilation can be applied as an outsole.

That is, when the cover member 10 constituting the inner insole of the shoe fills the elastic ball 20 having various specifications and various strengths (elasticity) with protrusions according to the shape of the sole of the foot in its inner space, the movement of the sole However, it can reduce the impact caused by the load, massage the feet, and provide excellent ventilation.

As another example, the cover member 10 is manufactured as a tire structure as shown in the attached FIG. 9 or manufactured to have any one shape among a hole vest, a hole tube, and a water play tube as shown in the attached FIG. 10 It can be.

In addition, the cover member 10 can be manufactured to have the shape of the expansion joint pad structure as shown in FIGS. 11 and 12. In this case, the cover member 10 has a contact wing F1 and is a building or road Alternatively, it is possible to connect the connection parts of the concrete walls 100 constituting the retaining wall.

As described above, the cover member 10, which can be manufactured and applied in shapes required in various fields, is composed of a soft polyurethane material manufactured in various shapes to have a hollow space (not shown).

When the cover member 10 is a plate-shaped pad structure or an expansion joint pad structure, fine ventilation holes 10a may be formed.

Therefore, the outer circumferential surfaces of the upper cover 11 and the lower cover 12 are bonded together so that the cover member 10 formed of a plate-shaped pad structure or an expansion joint pad structure forms the hollow space, As shown in FIG. 2, boundary projections 10b facing each other are formed on the inner upper and lower surfaces, and/or as shown in the accompanying Fig. 3, the boundary projections 10b may be connected by a connecting member 10c. will be.

Here, the cover member 10 has been described as being made of a soft polyurethane material, but the upper cover 11 is made of soft fibers or hard polyurethane, and the lower cover 12 to be given flexibility and balance. ) may be composed of hard polyurethane or soft fibers.

On the other hand, in the case where the cover member 10 is a protective patch (e.g., nangsim, chest, etc.) attached to an athletic suit (taekwondo, baseball, boxing, kendo, etc.), the cover member 10 ) It may further include a whistle member 30 that generates an alarm sound due to the air moving through the elastic balls 20 according to the volume change of the space portion (not shown) when an impact is applied to the ).

That is, as shown in FIG. 13, the whistle member 30 does not generate an alarm sound when the air movement is less than a certain amount due to an impact pressure of less than a certain amount applied to the cover member 10, and the cover member A first air channel (31) having a first length (L1) and a first width (W1) so as to generate an alarm sound when a certain amount of air moves due to an impact pressure of a certain amount or more applied to (10), the first A second air passage 32 having a second length L2 shorter than the length L1 and a second width W2 lower than the first width W1, and branching from the first air passage 31 It includes a whistle flow path (33).

The elastic balls 20 are filled in a plurality of sizes in the space of the cover member 10, that is, innumerable amounts of small circular balls (10 to 80 mm), as shown in FIG. 5, the elastic On the surface of the ball 20, protrusions 21 and grooves 22 are repeatedly formed so as to form a planar connecting body structure by being continuously coupled in the longitudinal and transverse directions while being mutually coupled with the adjacent elastic balls 20, thereby forming the elastic The space formed between the balls 20 is capable of maintaining about 20% of the total volume of the space of the cover member 10 in which the planar connector is accommodated.

In other words, since the elastic ball 20 has a mutually repeating regular shape of the protrusions 21 and grooves 22 on its surface, a stable mat-type planar connector structure can be achieved while male-female coupling in any direction. In the case of manufacturing this as an internal shock absorber of the pad structure, if only the contact area with the upper and lower covers 11 and 12 constituting the cover member 10 is bonded, even if the impact is strongly received on one side, the cover member 10 It is possible to effectively prevent the phenomenon that the elastic ball 20 accommodated inside is biased to one side. Therefore, the frame of the cover member 10 can be maintained constant.

Here, the elastic ball 20 is a soft polyurethane material having elasticity, which may be a sphere or cube-shaped elastic structure having a certain space on the inner surface, formed on the surface of the elastic ball 20. The protrusion 21 to be can be fitted into the fine ventilation hole 10a formed in the cover member 10 .

The elastic balls 20 that are continuously coupled in either direction or both directions of the longitudinal direction and the transverse direction to form a planar connector structure may be adhesively fixed to the inner surface of the cover member 10. In this case, in the accompanying FIG. 4 As such, one or at least one flat area 20a may be formed on the elastic ball 20 to enable stable contact and fixation with respect to the inner surface of the cover member 10.

On the other hand, when the protrusion 21 formed on the surface of the elastic ball 20 is fixedly coupled in a form inserted into the microhole 10a of the cover member 10, it is formed between adjacent elastic balls, It is connected to the existing space and provides excellent air permeability and cushioning.

In other words, since it is laminated by connecting the elastic balls 20, the volume is maintained as much as the height of the elastic balls 20 to be stacked, but when a load is applied from the top, the elastic balls that are continuously coupled in the transverse direction When the flat connector, which is the connection structure of (20), is pressed in a state where movement is inhibited from side to side, the cross section of the elastic ball (20) is pressed in a shape close to a square by the upper cover (11) while maintaining a unit volume The height is changed while the rear is deformed, and as a result, it is stretched in a limited range in the lateral direction, and when the load applied to the top is removed, the elastic ball 20 recovers to its original shape and provides excellent cushioning properties. There is.

In particular, when the cover member 10 is applied as a protective patch for athletics (nose core, chest, etc.), it is beneficial for player protection by a buffering action that absorbs impact force, and when a blow is applied from an opponent player, depending on the impact As the cover member 10 is pressed, the air between the balls goes out to the space where the whistle member 30 is located and emits a sound, so that the match party can quickly and effectively recognize whether the opponent is hitting.

Meanwhile, in the elastic balls 20 accommodated at least one in the space of the cover member 10, the inside of the elastic balls 20 accommodated and disposed in the middle region of the space effectively absorbs external impact. And air of a certain volume (eg, approximately 1/3) may be filled to absorb the impact by using the elastic repulsive force.

Here, when the elastic ball 20 is applied to sports shoes as shown in FIG. 6, the elastic ball 20 is connected in the transverse direction to form a plate-shaped pad structure and is accommodated on the inner surface of the cover member 10 By arranging the size and elastic density in various combinations, it is possible to provide functional shoes with increased wearing comfort. As shown in FIG. 6, the outsole is combined with elastic balls 20 with a diameter of 10 mm to form a mat-type flat connector having a sense of stability, while the insole located on the upper part is micro-elastic with a diameter of about 2.0 mm. By connecting and combining the balls 20 ', it is possible to construct a flat connector in the form of a flexible mat.

In addition, considering the functional position, it is also beneficial to combine and connect a soft polyurethane material with relatively excellent elasticity compared to the outer part for the bending section (L1) so that flexibility can be added to the front folding part of the shoe.

When the elastic ball 20 is applied to a bicycle saddle as shown in FIG. 7, the entire surface of the saddle cover is combined with elastic balls 20 having a diameter of 10 mm to form a stable mat. Although it constitutes a plane connecting body, micro elastic balls (20') with a diameter of about 2.0 mm are arranged on the circumferential surface, which rubs against the user's calf and repeatedly applies stimulation, to increase elasticity. Flexibility can be added. It can be configured so that

On the other hand, as shown in FIG. 8 to which the elastic ball 20 is attached, it is applied to a vehicle tire, and when filling the inside of the cover member 10 constituting a tubular structure, the inside of the elastic ball 20 contains nitrogen gas. can be filled.

That is, the elastic ball 20 is densely packed inside the vehicle tire constituting the cover member 10 to enable safe operation even with a sudden puncture while driving, which can be effectively applied to a cargo truck.

In this case, the overall load may increase due to the elastic ball 20 filled inside the tire, but this can improve driving stability, and when nitrogen gas is filled inside the elastic ball 20, the inserted It is possible to offset the increase in load due to the weight of the elastic ball (20).

In addition, when the elastic ball 20 fills the inside of the cover member 10 manufactured in a tube shape, the projection 21 and the groove 22 on the surface of the elastic ball 20 have a mutually regular coupling structure. Since it has, it is possible to prevent the elastic ball 20 filled inside the cover member 10 from being biased to one side, and to provide a buffer of uniform distribution as a whole, regardless of road conditions. This will ensure driving stability.

On the other hand, the elasticity of the conventional sponge is determined according to the physical properties of the raw material, and therefore it is impossible to vary the partial elastic area, but in the present invention, the cover member 10, which is a plate-shaped pad structure, is an elastic ball ( Since the degree of elasticity varies depending on the thickness of 20), a pad structure having various distributions may be provided by arranging and combining balls in a required combination.

That is, the pad structure can use the elastic balls 20 in various sizes, starting from microballs having a diameter of 2.0 mm, and as shown in FIGS. 1 to 4, flat connectors are stacked in at least one layer. As shown in FIG. 9, when the pad structure having the planar connector is attached to the inner surface of a motorcycle or other occupant protective helmet or a baseball player protective helmet, an elastic protective layer is formed evenly on the entire surface. In addition, since it has air permeability, it prevents damage to the wearer's hairstyle, and therefore does not act as a factor to avoid even for users who value appearance.

That is, by varying the size and elasticity of the elastic ball 20 according to the strength and weakness of the head structure and the internal and external positions, the impact on the brain can be reduced, and the impact applied from either side can be effectively absorbed, and the head If you scan the shape, it is composed of small balls, so you can easily fit the liner ergonomically with any shape of head structure, and air can flow between the spaces between the elastic balls (20), so external matters can be detected and intake and exhaust can be performed well. will be.

In addition, as shown in the attached FIG. 10, when the cover member 10 forms an outer shell of a life jacket, life tube, life boat, etc. and a plurality of elastic balls 20 are filled therein, safety due to air loss Accidents can be avoided, and while changing the size and elasticity of the elastic ball 20 depending on the position, it is less comfortable to wear, has natural movement, closely adheres to the body, and obtains a slim size and more deformed design.

Therefore, even if the conventional tube structure enjoys water play in the sea or river, when the surface of the tube is damaged by the branches of nearby waterside plants or sharp foreign substances during water play, the air stored inside quickly escapes and loses buoyancy. Therefore, it is impossible to request a rescue or to secure time until a rescuer arrives, and therefore, it is impossible to prevent a serious safety accident even in a rescueable environment. 20) is made of a cover member 10 filled with countless amounts, even if a part of the surface of the cover member 10 is damaged due to contact with a floating object during water play, the elastic ball 20 accommodated therein will not affect it.

Therefore, it is possible to maintain a certain buoyancy under any circumstances, and even in such a dangerous situation, it is possible to provide beneficial advantages in preventing and preventing safety accidents, such as requesting rescue or quickly escaping from a dangerous area.

In this way, the shock absorbing buffer pad elastic structure according to the embodiment of the present invention manufactures the cover member 10 constituting the outer shell of various products, as shown in the attached FIGS. 1 to 13, while the cover member 10 ) In a state in which a plurality of elastic balls 20 are filled in the hollow space portion of the interior, the whistle member 30 is selectively applied.

At this time, the elastic ball 20 is mutually coupled with adjacent elastic balls by the protrusions 21 and grooves 22 repeatedly formed on the surface, and can form a flat connecting body structure that is continuously coupled in the transverse direction.

Therefore, when an external force is applied to the cover member 10 constituting the outer shell, and the external force causes a change in the volume of the hollow space portion inside the cover member 10, the planar connection structure filled in the space portion The elastic ball 20 constituting the is to be able to provide a buffering property of uniform distribution by maintaining the frame while preventing the phenomenon biased to one side.

Then, when an external force is applied while wearing or attaching the cover member 10 constituting the outer shell, the external force is applied to the cover member 10 as well as the hollow space formed in the cover member 10 It is possible to protect the user from impact while being continuously multi-stage absorbed by the volume change of the part and the elastic ball 20 filled in the space part.

On the other hand, while attaching the cover member 10 forming the outer shell to form a protective patch-type pad (eg, chest, chest, etc.) to the athletic suit, in the case of applying the whistle member 30 to the cover member 10, the When an external force is applied to the cover member 10, it is possible to generate an alarm sound due to the air exhausted to the outside, which is beneficial for player protection by a buffering action that absorbs impact force, and when a blow is applied from the opponent player, the impact Accordingly, as the cover member 10 is pressed, the air between the elastic balls 20 goes out to the space where the whistle member 30 is located and emits a sound, so the match party can quickly and effectively recognize whether the opponent is hitting There is.

In the above, the technical concept of the shock absorbing buffer pad elastic structure of the present invention has been described together with the accompanying drawings, but this is an exemplary description of the most preferred embodiment of the present invention, but does not limit the present invention.

Therefore, the present invention is not limited to the specific embodiments described above, and various modifications can be implemented by anyone having ordinary knowledge in the art to which the present invention belongs without departing from the gist of the present invention claimed in the claims.
