Description

[Technical field]

[0001] The present invention relates to a method for producing a cushioning element for sports clothing, in particular for sports shoes. Regarding the law. [Background technology]

[0002] Cushioning elements are very important in the field of sports clothing and are used for a wide variety of sports. Examples of this include winter sports clothing, running clothing, There are outdoor clothing, football clothing, golf clothing, martial arts clothing, etc. These cushioning elements serve to protect the wearer from impacts and blows, as well as to provide protection against, for example, It acts as a padding when the wearer falls. Typically, one or more of these materials deform under external pressure or impact, thereby absorbing the impact energy. Contains multiple transformation elements.

[0003] Cushioning elements play a very important role in the construction of shoes, especially sports shoes. With the aid of cushioning elements arranged in the sole or as part of the sole, the shoe is particularly It has a variety of different features that can be noticeable in terms of different strengths depending on the particular type of shoe. Primarily, these shoe soles have a protective function. Due to their high rigidity, the shoe sole is resistant to the force of sharp objects that the shoe wearer steps on. In addition, shoe soles generally have enhanced wear resistance. The abrasion resistance protects the shoe from excessive wear. In addition, the shoe sole is This can increase the grip of the shoe on the ground and therefore promote faster movement. A further function of the shoe may be to provide some stability. The sole is designed to provide cushioning, for example to absorb the force generated when the shoe strikes the ground. Finally, the shoe sole can protect the foot from mud or splashes of water. It is possible to provide protection and / or perform several other functions.

[0004] In order to meet these multiple functionalities, various cushioning elements for sports clothing can be produced. The materials and methods of manufacture are known in the prior art.

[0005] Examples include ethylene vinyl acetate (EVA), thermoplastic polyurethane (TPU), and rubber. , polypropylene (PP) or polystyrene (PS) shoe soles Each of these different materials is a cushioning element for each shoe type. Various soles are more or less well suited to particular shoe types depending on the specific requirements of the user. It offers a unique combination of properties. For example, TPU is highly resistant to abrasion and wear. Furthermore, EVA is known for its high stability and relatively good cushioning characteristics. This is particularly evident in

[0006] Furthermore, the use of foamed materials has been considered for producing shoe soles. Thermoplastic polyurethanes (eTPUs) are disclosed in WO2008 / 087078, WO2007 / 082838, WO2010 / 136398, and WO2005 / 066250 Foamed thermoplastic polyurethanes are known due to their light weight and particularly good elasticity and shock-absorbing properties. Furthermore, according to WO2005 / 066250, a foamed thermoplastic polymer Soles made from polyurethane are bonded to the shoe upper without the use of additional adhesives. The adhesive can be fixed to the substrate.

[0007] EP1854620A1 teaches a method for filling cavities with expanded particles. DE202008017042U1 is a method for producing a liquid crystal display device made of particles of a synthetic material having a partially closed surface. DE 4236081 A1 discloses a molding tool for producing a foam component. The present invention relates to a method for manufacturing components from foamed synthetic materials and a mold for carrying out such a method. DE19652690A1 describes a component, a method for producing and DE202010008893U1 describes a method for producing a semiconductor device using a semiconductor laser and an apparatus for carrying out the method. , discloses an apparatus for producing a particle foam component.

[0008] To produce particles from a foamed thermoplastic urethane, the thermoplastic urethane is, for example, first To achieve this, the foam is filled with a blowing agent in a suspension or extrusion process and then heated to a temperature of 100°C. For example, thermoplastic urethanes can be stored in water initially. whereby the water is absorbed by the thermoplastic urethane and in a further step The mixture is then vaporized to give a thermoplastic urethane foam.

[0009] For example, the midsole is made of EVA, the torsion element is made of TPU, and the a Manufacture of soles for shoes, such as outsoles, adhesive cushioning elements made of modified EVA, etc. Various components for the production of the shoe are then fabricated in a further manufacturing step. Its assembly into a sole is known from the prior art.

[0010] One drawback of the manufacturing methods known from the prior art is that these methods do not, as just described, This involves the manufacture of various individual parts of the cushioning element that will later need to be connected to each other. This is because, for example, different moulds can be used to manufacture individual parts, Each separate part must be released from these molds and inserted into a new one, and The possibility of influencing the characteristics of the cushioning elements during the manufacturing process is almost limited. This will result in significant additional costs. [Prior art documents] [Patent documents]

[0011] [Patent Document 1] WO2008 / 087078 [Patent Document 2] WO2007 / 082838 [Patent Document 3] WO2010 / 136398 [Patent Document 4] WO2005 / 066250 [Patent Document 5] EP1854620A1 [Patent Document 6] DE202008017042U1 [Patent Document 7] DE4236081A1 [Patent Document 8] DE19652690A1 [Patent Document 9] DE202010008893U1 Summary of the Invention [Problem to be solved by the invention]

[0012] Based on the prior art, therefore, one object of the present invention is to provide a method for producing a cushioning element for sports clothing. In particular, one object of the present invention is to provide an improved manufacturing process for By increasing the possibility of influencing the characteristics of the cushioning elements during the manufacturing process, This reduces the number of steps, simplifies the manufacturing process, and enables highly automated production. The present invention provides a method for manufacturing a cushioning element for a garment. [Means for solving the problem]

[0013] According to a first aspect of the invention, these objects are achieved by the use of a randomly generated foamed material. The method for producing a cushioning element for sports clothing from a plurality of arranged particles provides a method for producing a cushioning element for sports clothing from a plurality of arranged particles. This method at least partially achieves this by filling a mold with a plurality of particles of a foamed material. The particles are then packed into a mold in a transport liquid and / or vapor stream. It is filled inward.

[0014] The use of multiple particles of foamed material allows for the storage and Due to the particular ease of construction and handling, the manufacturing process for the cushioning element is significantly facilitated. Also, by filling the mold with particles with the assistance of liquid and / or vapor flow, The particles are packed as uniformly as possible without the need for additional particle distribution during This reduces the risk of defects in the material of the cushioning element and simplifies the manufacturing process. This allows for a significant simplification of the process.

[0015] In a preferred embodiment, a plurality of particles of foamed material are formed in a mold. The mixture is treated with pressure and / or heat and / or steam.

[0016] Thereby, the particles of the foamed material are formed, for example, at least on the surface of the particles. In a particularly preferred embodiment, The particles are chemically bonded by pressure treatment and / or heat treatment and / or steam treatment. Such bonds are particularly durable and long-lasting and do not require the use of additional bonding agents, e.g. adhesives. In addition, the pressure treatment and / or the treatment temperature, treatment duration, etc. may be adjusted. or changes in the parameters of the heat and / or steam treatment may result in changes in the characteristics of the cushioning element during manufacture. It is possible to affect the symptoms.

[0017] In a further embodiment, the plurality of particles of the expanded material are subjected to pressure. The mixture is then filled into the mold.

[0018] This allows the particles to be already in a compressed state when introduced into the mold, This is prior to the additional manufacturing step where the pellets are compressed in the mold only after they have been filled into the mold. By changing the pressure at which the particles are packed into the mold, it is possible to manufacture, for example, The density of the material of the cushioning element can further be influenced.

[0019] In a further embodiment, the transport liquid is subjected to pressure and / or heat and / or steam. The mold is at least partially removed from the mold prior to treatment with air.

[0020] In one embodiment, the residual transport liquid is preferably pressure-treated and / or heat-treated and The transport liquid then solidifies in the mold under the influence of heat and / or steam treatment. It has further functions in the manufacture of the shock absorbing element and can further influence the characteristics of the shock absorbing element. This again leads to a significant simplification in the manufacturing process. The body can, for example, improve the stability of the cushioning element and its tear strength. This allows, for example, the production of very thin and very light cushioning elements.

[0021] In a further embodiment, the liquid and / or the solidified liquid is subjected to pressure treatment and / or after completion of the heat treatment and / or steam treatment, at least Also partially dissolved and / or melted and / or removed.

[0022] This allows, for example, a further reduction in the density and therefore the weight of the cushioning element.

[0023] A further aspect of the present invention is a process for filling a mold with a plurality of particles of a foamed material. A sports garment made of randomly arranged particles of a foamed material, including a The method comprises the steps of: forming a cushioning element for a material by forming a cushioning element for a material by forming a cushioning element for a material on a wall of a mold; and forming a plurality of particles of foamed material adjacent to said portion of the mold wall. The method further comprises the step of heating to a temperature that causes partial or complete melting.

[0024] Within the mold, the foamed material adjacent to the mold walls is at least partially already melted. As a result, the surface features of the cushioning element can be fabricated without requiring additional manufacturing steps. This could have a far-reaching and even further impact.

[0025] In one embodiment, the particles of the foamed material are compressed in a mold under pressure and and / or further treated with heat and / or steam.

[0026] In a further embodiment, the portion of the mold wall that is heated by the method described above comprises: It has a structured surface.

[0027] This can serve, for example, as an optical design. When designed as a ball, the surface structure may be, for example, a pusher for the sole to improve traction. It can be designed as a profile.

[0028] In one embodiment, the at least partially melted particles, after cooling, form a cushioning element. It is configured to be selectively cured.

[0029] Partial melting and cooling results in a change in the density and / or mass of the partially melted particles on the surface. The stiffness or rigidity may be increased, for example, as compared to non-fused particles in the interior of the cushioning element. The structure may be further structured, for example having a lattice or honeycomb or rib shape. By obtaining the above-mentioned structure, the stiffness of the cushioning element can be selectively increased in one or more directions. This becomes possible.

[0030] According to a further aspect of the present invention, a randomly arranged plurality of foamed materials is provided. The method for producing cushioning elements for sports clothing from particles of foamed material is The method includes filling a mold with a plurality of particles and then filling the particles with a liquid matrix material. The coating provides a substantially uniform distribution of the particles in the matrix material. This includes the step.

[0031] In a preferred embodiment, a plurality of particles and / or The matrix material is further treated with pressure and / or heat and / or steam.

[0032] Further improvements in achieving uniform particle distribution are achieved by coating the particles with a liquid matrix material. At the same time, the matrix material can assume any kind of additional function. For example, the matrix material may be pressure-treated and / or heat-treated and / or or steam treatment, resulting in a higher tear strength. At the same time, the matrix material provides high flexibility. It is also possible to provide protection.

[0033] A further aspect of the invention is a method for producing a foamed material comprising the steps of placing a functional element in a mold and and filling the mold with a plurality of particles comprising: The filling step is carried out by at least two openings of different types. A randomly arranged foamed material is placed between multiple moving parts. The present invention comprises a method for producing a cushioning element for sports apparel from a plurality of particles.

[0034] This allows the functional element to be attached without the need for an adhesive bond between the cushioning element and the functional element. The functional element can be fixed in the cushioning element without any form closure between the functional element and the cushioning element. Alternatively, the functional element may be adhesively bonded to the cushioning element during manufacture. For this purpose, the functional elements can be, for example, bonded prior to placement in the mold. The adhesive may be coated with an adhesive agent such as a glue.

[0035] Thus, in one embodiment, a plurality of particles of foamed material are placed in a mold. The material is treated with pressure and / or heat and / or steam.

[0036] Also, an additional bond between the functional element and the cushioning element can be established hereby. By varying the manufacturing parameters, the characteristics of such bonds can be further influenced, e.g. It becomes.

[0037] In a preferred embodiment, at least two openings are made of a foamed material. The packed particles are arranged to surround the functional element from at least two different sides.

[0038] This means that the functional element is covered as much as possible from all sides by a number of particles made of foamed material. This ensures that the cushioning element is more uniformly surrounded, thus avoiding defects in the cushioning element to a large extent. This is particularly advantageous for functional elements which have a flat design.

[0039] In a particularly preferred embodiment, the functional element is arranged within the cushioning element just described. Various aspects of the method for bonding the molded article include, for example, a method in which a portion of the mold wall is heated and bonded. This may be combined with one embodiment of the method further described above.

[0040] This allows the characteristics of the cushioning element to be selectively modified in various ways by using only one mold. It is possible that the impact of

[0041] In another preferred embodiment, the functional element itself is made of a liquid matrix material as described above. The method is produced by coating a plurality of randomly arranged particles of a foamed material with The cushioning element is formed of a material having a thickness of 100 mm or less.

[0042] In another preferred embodiment, the functional element is a foil, in particular a thermoplastic The foil comprises a resistant urethane.

[0043] Such foils can affect the characteristics of the cushioning element in several different ways. For example, the foil can play a role in the optical design or provide additional stability to the cushioning element. This foil can be used on the one hand for optical design purposes, e.g. It is possible to enclose a cushioning element externally, for example in order to improve stability. It is also possible to arrange the foil in the cushioning element, for example in the form of air and and / or may be arranged to allow liquid to pass through in only one direction. The foil is implemented as a membrane and provides a ventilation system that simultaneously protects the wearer against external moisture. For this purpose, thermoplastic urethane is used. Foils containing urethane are particularly useful, especially in combination with particles made of expanded thermoplastic urethane. This is advantageous because they are highly resistant to chemical reactions with such foils. This is because it can initiate academic connections.

[0044] The foil may, for example, provide a closed surface structure for the cushioning element. Foils can be useful for enhancing durability or for decorative purposes. When used, for example when walking, the cushioning element may be used in the sole of a shoe, and may be It also acts as a "functional skin" that controls the movement and expansion of the foamed material of the impact element. For example, the foil may surround the foamed material of the cushioning element in certain areas and Therefore, to limit the expansion and / or movement of the foamed material in this area, This may be desirable in areas where high stability is important. .

[0045] On the other hand, the foil may be used in places where the foam is not easily absorbed, for example in the toe area of ​​the shoe sole. In areas where the high energy recovery capacity of foamed materials can be beneficially utilized, The "free" regions, in which the trapped material is allowed to move and expand to a greater extent, are defined as, for example, It may also be used to form in such a manner as described further below.

[0046] In particular, the functional element is a plurality of randomly arranged particles of a second foamed material. It is possible for the foil to be provided as a container or "bag" for containing the The second foamed material may be the same as the foamed material of the cushioning element described above. (hereinafter simply referred to as the "foamed material"). However, the second foamed material , it is also possible for the material to be different from the foamed material.

[0047] Such a container allows for the storage of many different shapes of cushioning elements without the need for dedicated molds. disposing a plurality of randomly arranged particles of a second foamed material in the region; In particular, this allows the secondary foaming of the cushioning element in a simple manufacturing process. It is possible to arrange a plurality of randomly arranged particles of a selected material.

[0048] A number of different options are possible: the foil forming the container may be porous, for example It may be porous, may have perforations, may have a mesh-like structure, or may have a different structure. In the manner described above, the second emitting layer may be permeable to heat and / or steam. The plurality of particles preferably comprises a foamed material of the cushioning element. The particles are also treated with pressure and / or heat and / or steam in a mold. In this case, the foil and possible openings of the container can be sealed from the second foamed material. and preferably further comprising a foamed material. It should be small enough that it is not possible for it to pass through these openings.

[0049] In such a process, the foil is decomposed to become a foamed material. a plurality of randomly arranged particles of a first material and a plurality of randomly arranged particles of a second material; However, the foil may also be retained within the cushioning element. The foil may thus be made up of a plurality of particles of a foamed material and a second It may also act as a binder between multiple particles of foamed material. In this case, the foil serves as a "functional skin" as described above, for example. It may exhibit further functionality, such as:

[0050] For example, the density of the randomly arranged particles of the second foamed material may be: The density of the randomly arranged particles of the foamed material is higher than that of the second foam. A foil of foamed material surrounding the particles is disposed within the second foamed material within the cushioning element. This provides areas of high stability by further restricting the movement and expansion of the trapped material. It is possible.

[0051] The density of the randomly arranged particles of the second foamed material is also The density of the randomly arranged particles of foamed material can be lower than that of the Thus, a plurality of particles of the second foamed material are "liberated." This leads to more pronounced movement and expansion of these particles, and to the possibility of them collapsing when, for example, walking on a stepping-off platform. A region that allows high energy return to the user is formed within the cushioning element, They may be provided in essentially any desired shape and / or location within the element.

[0052] Furthermore, the foil, in particular a plurality of randomly arranged foils of a second foamed material, A foil that serves as a container for containing particles, even if not expressly described , any other method, practice of the invention described herein or that would occur to one of skill in the art. It should be clearly noted that the term may be used in conjunction with any of the above aspects or modes. Such foil containers having a plurality of particles of foamed material are made of foamed material. Alternatively, multiple particles can be placed in a mold that is filled in the vapor / transport liquid stream. It is.

[0053] In a preferred embodiment, the functional element comprises a plurality of particles of foamed material. Does not include.

[0054] The functional elements can be assembled in a flexible manner without the use of adhesive binders by utilizing the manufacturing method described above. This allows a large number of materials to be used to design such functional elements, since they can be fixed in the impact element. In particular, the materials used are in contact with the foamed material of the cushioning element. This allows for a great deal of freedom in terms of configuration.

[0055] According to a further aspect of the invention, there is provided a method for the preparation of a medicament for use in the method described herein. a plurality of particles of a first expanded material and / or a second expanded material; The particles may vary in material and / or size and / or density and / or color. It comprises a mixture of at least two different types of particles.

[0057] The cushioning elements are characterized by foamed materials that vary in material, size, color, density, etc. The right combination of different particle types allows for a wide range of cushioning properties depending on the requirement profile of the cushioning element. This can be affected in various ways in the manufacturing methods mentioned herein. A number of combinations for influencing the manufacture of the cushioning element, in combination with one or more This results in a variety of possibilities and options.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0070] The presently preferred embodiment of the present invention is directed to a method for manufacturing soles for sports shoes. The detailed description below primarily relates to the method for It should be emphasized that the present invention is not limited to these embodiments. For example, the present invention is applicable to winter sports clothing, Running clothing, outdoor clothing, football clothing, golf clothing, martial arts clothing, etc. The invention can also be advantageously applied to a method for producing cushioning elements for individuals.

[0071] FIG. 1 shows a schematic diagram of a method 100 for manufacturing a cushioning element. A plurality of randomly arranged particles 110 of a material that is The step of filling the mold 120 is comprised of a first portion 122 and a second portion 125. The particles 100 are now transported through a transport liquid flow and / or vapor flow 130. It is filled into 120.

[0072] A liquid flow and / or vapor flow 130 is used to aid in the transport into the mold. In a preferred embodiment, the transport liquid is water. In this case, a powder that behaves like a liquid is used as the transport liquid, which allows the foamed material to be The material prevents the plurality of particles 110 from adhering to each other and / or from being interconnected. One example of such a powder is Luwax® OP P available from BASF. Other materials having similar characteristics would be equally suitable.

[0073] For this purpose, the particles 110 are first transferred to a transport liquid or vapor in, for example, a collection vessel 140. The mixture is mixed with the air and then pumped through the inlet pipe 150 into the mold 120. FIG. 1 only shows a single inlet pipe 150 and a single inlet. However, the present invention contemplates that the particles 110 may be fed through two or more inlet pipes 150 and / or through two or more inlet pipes 150. It is to be clearly noted here that the present invention also includes embodiments in which the mold 120 is filled through more than one inlet. Keep it.

[0074] In a preferred embodiment, the particles 110 in the liquid and / or vapor stream 130 are The foam is then filled into the mold 120 under pressure. This allows the foam to be filled into the mold 120 already when the mold 120 is filled. The material of the cushioning element is compressed to a certain degree by a plurality of particles of the material. Therefore, the density of the material of the cushioning element to be manufactured is In particular, the pressure for packing the particles in the liquid and / or vapor stream 130 into the mold 120 Determined by force.

[0075] In a further embodiment of the method 100, the transport liquid and / or vapor is foamed. The desired amount of particles 110 of the mixed material may be removed at least partially or further from the mold 120 after the introduction of the mixed material. For example, to this end, the mold 120 may be filled with the transport liquid after the introduction of the particles 110. It has a series of openings (not shown) that allow for the removal of body and / or vapor. For example, the opening may be connected to a vacuum system (also not shown) that draws in aspiration. The transport liquid and / or vapor is extracted from the mold 120 by.

[0076] The foamed material is filled into the mold 120 with the assistance of liquid and / or vapor flow 130. By using a plurality of randomly arranged particles 110 of the material, such a buffer can be achieved. In particular, the liquid and / or vapor flow 130 allows the lamination of the lamination. It is ensured that the randomly arranged particles 110 are filled into the mold 120 as uniformly as possible. This reduces the risk of defects forming in the material of the cushioning element. The method may be used with additional functional elements (not shown) that are placed within the mold 120 prior to filling. It is particularly preferred that the liquid and / or vapor flow 130 is arranged on all sides. circulates through this element, thus transporting the particles 110 to multiple sides of the functional element. This makes it possible to reduce the risk of defect formation in the cushioning element.

[0077] In combination with the liquid flow and / or vapor flow 130, a laminar flow of foamed material is formed. The use of a plurality of randomly arranged particles 110 is particularly advantageous because The particles 110 do not require any special configuration and are resistant to such liquid flow due to their low density. and / or because it can be easily transported into the vapor stream 130.

[0078] In a further embodiment, after filling of the mold 120, the particles 110 are subjected to a pressure treatment and and / or exposed to heat treatment and / or steam treatment. After filling the mold 120 and before pressure / heat / steam treatment, the inlet pipe 150 (combined The opening(s) or, rather, the inlet opening(s) of the mold 120 are closed. or a plurality of particles 11 made of a foamed material by heat treatment and / or steam treatment. The bonding occurs, for example, by a slight melting of their surfaces. In the form, the particles 110 are pressure treated and / or heat treated and / or steam treated. Such a bond is particularly permanent and resistant, and can be achieved by using adhesives, etc. The exact nature of the bond that occurs between the particles may be determined by the pressure treatment. and / or heat treatment and / or steam treatment, e.g. pressure, temperature, duration, and treatment time. It is determined by strict parameters such as the theory and so on.

[0079] In a further optional embodiment of this method, the transport liquid is partially removed from the mold 120. The remaining liquid is removed naturally or by the application of the pressures mentioned above. Solidification in the mold 120 under the effect of processing and / or heat treatment and / or steam treatment The transport liquid is therefore important in the manufacture of cushioning elements for sports clothing as well as in the materials and It can take on additional functions that further reduce production costs. For example, solidified transport liquid The body may further increase the tear strength of the cushioning element.

[0080] In a further embodiment, the transport liquid and / or the solidified liquid are further pressurized. After completion of the force treatment and / or heat treatment and / or steam treatment, by pressure or buffer At least partially dissolved and / or melted and / or by other means from the element It can be removed.

[0081] By combining the various aspects of the inventive manufacturing method described herein, Thus, the characteristics of the method and of the cushioning element so produced can be affected in a number of ways.

[0082] A further method 20 for producing a cushioning element for sports clothing according to an embodiment of the invention 0 is shown diagrammatically in FIG. 2, which is a randomly generated The method includes filling a mold 220 with the plurality of particles 210 arranged therein. 00, the mold 220 includes a first portion 222 and a second portion 225. Thus, after completion of the manufacturing process described above, both portions 222 and 225 This allows for easy removal of the cushioning element from the mold 220 by opening the molds 220 relative to each other. However, it should be clearly understood that the configuration of mold 220 shown herein serves only as an example. The method 200 may be used in conjunction with a single segment or with three or more segments. The same applies to differently configured versions of the type shown diagrammatically in FIG. The same is true for the manufacturing method shown.

[0083] In a preferred embodiment of the method according to the present invention, the method 200 is carried out in a mold made of metal. The wall portion 230 of the 220 is made of foamed material adjacent to the wall of the portion 230. and heating the mixture to a temperature causing partial or complete melting of the plurality of particles. Preferably, the portion 230 of the wall of the mold 220 is configured such that a current does not flow through the portion. For example, one or more conductor spirals may be inserted into this portion 230 of the wall. The conductive spiral is arranged so that a current can flow through it to heat the walls of the mold 220. In another embodiment, the current flow is induced by electromagnetic induction. 2, but selectively turned on and off at individual portions 230 of the wall of the mold 220. By switching between different areas of the cushioning element, different areas of the cushioning element can be affected using a single mold 220. One embodiment in which the material can be subjected to high temperature water / steam or other means is particularly preferred. For example, a cavity in the mold 220 for increasing the temperature by flowing or for subsequent cooling. Other approaches to temperature control, such as via a cavity (not shown), are also contemplated.

[0084] Additionally, a plurality of randomly arranged particles 210, as already described above, are placed within the mold 220. It may also be subjected to pressure treatment and / or heat treatment and / or steam treatment in be.

[0085] According to a further aspect of the invention, at least a portion 230 of the wall of the mold 220 is heated. has a structured surface. The structure may be, for example, a honeycomb shape, a corrugated shape, a lattice shape, a ribbed shape, etc. The mold 220 may be embossed, zigzag, or designed in any other manner. By appropriately selecting the structure of the heated portion 230 of the wall, the surface of the cushioning element can be adjusted The characteristics of the corresponding parts can be influenced as desired. Thus, for example, The method 200 described herein is directed to a cushioning element designed as a shoe sole. This can be used to stamp out structures that are visible on the ground, for example. Such a structure can increase the slip resistance of the ball. It is also possible for the object to play more of a role in optical design and decoration.

[0086] In a further embodiment of the method 200 described above, the at least partially molten particles are The mold 220 is further configured to selectively harden the cushioning element after cooling. The particles located in the area of ​​the heated portion 230 of the part are partially melted and then cooled. As a result, the strength of these particles is such that they are more susceptible to the heat dissipated from the portion 230 of the wall of the mold 220. This is because the melting temperature in this area is increased compared to the grains that were not even partially melted. This results in an increase in the stiffness of the cushioning element at the center of the cushion. 2 and 3, which is designed to have the structure described above. By combining these, the behavior of the cushioning element, and in particular its stiffness, can be selected in individual areas. It is possible to selectively be affected.

[0087] 3 and 4 show a cushioning element manufactured by the method 200 described herein. Examples of surface designs for 300 and 400 are shown. The cushioning element 300 is made up of individual honeycombs 310 and The honeycomb-shaped surface is composed of the honeycomb 310 and the thin channel 320 located between the honeycombs. For example, the honeycomb 310 allows the cushioning element 300 to be set up as a shoe sole. In this case, a larger support surface of the cushioning element 300 is provided. For example, the channels 320 can absorb liquid displaced during walking, which , which has a positive effect on the slip resistance of such soles.

[0088] On the other hand, the cushioning element 400 is composed of irregular protrusions 410 and recesses 420. It has a surface.

[0089] This results in a smaller bearing surface area of ​​the cushioning element compared to cushioning element 300. This reduces the pressure drop but also improves the ability to cause, for example, liquid displacement.

[0090] Furthermore, different designs of the surfaces of the cushioning elements 300 and 400 may affect the cushioning elements in different ways. Affects stiffness.

[0091] In short, the surface structure of the cushioning element and its stiffness are as described herein. By the method 200 and the appropriate selection of the structure of the portion 230 of the wall of the mold 220 that is to be heated, Thus, it can be affected in many different ways.

[0092] A further aspect of the invention is that the mold comprises randomly arranged multiple molds made of foamed material. The matrix is ​​filled with a number of particles, which are then coated with a liquid matrix material to form a matrix. Cushioning element for sports clothing, realizing substantially uniform distribution of particles in a cushioning material - Patents.com For example, liquid polyurethane, i.e. liquid PU , or a material having equivalent characteristics, is discussed as a liquid matrix material.

[0093] The use of a matrix material increases the likelihood that the characteristics of the cushioning element will be substantially constant, particularly This reduces the risk of defects occurring in the material.

[0094] In a preferred embodiment, a plurality of particles and / or The matrix material is further treated with pressure and / or heat and / or steam. The risk liquid may begin to bond with particles of, for example, solidified and foamed material. Moreover, these can be, as already mentioned above, for example by melting or The molecules are preferably allowed to initiate a bond between themselves through a chemical reaction. Therefore, the matrix liquid can have two functions. The body promotes as uniform a distribution of material as possible in the mould and on the other hand reduces the need for cushioning. It is therefore possible to further influence the features of the matrix. The liquid can, for example, increase the tear strength of the cushioning element or make it very thin. It can be used to produce very light cushioning elements. Depending on the relationship between the amount of particles of the foamed material and the material used, Accordingly, the cushioning element can be obtained with a variety of possible designs.

[0095] FIG. 5 illustrates randomly distributed particles that are substantially uniformly distributed in the solidified matrix material 520. 5. A midsole fabricated by the methods described herein having a plurality of particles 510 fabricated thereon. 5 shows an embodiment of a cushioning element designed as a midsole 500. It is extremely thin and very lightweight while having high tear strength and deformation ability. In the embodiment shown in 5, liquid PU was used as the matrix material.

[0096] A further method 600 for manufacturing a cushioning element according to an embodiment of the invention is shown in FIG. The method is shown diagrammatically in the example shown in FIG. A stamp 630 is used to place a functional element 640 in the mold. However, as with the embodiments of the method according to the invention described above, a setup of the type shown in FIG. The above-mentioned gauge should be regarded as an example only. For example, the functional element 640 may be fixed on a needle. 6, and can be placed into the molds 620, 630 therewith.

[0098] Further, the method 600 may further comprise removing at least one of the particles from the mold as shown in the upper portion of FIG. A plurality of randomly arranged foamed materials are formed through two openings 625, 635. The method includes filling a mold with particles 610 of at least two openings 625, 63. 5 is preferably closed after completion of filling 602 of the mold.

[0099] In a particularly preferred embodiment, the at least two openings 625, 632 are formed from foam. The particles 610 to be filled are made of a material that is mixed with the functional element 64 from at least two different sides. 0. This allows the particles 610 around the functional element 640 to A substantially uniform distribution is ensured and therefore the risk of defect formation in the material of the cushioning element is reduced Depending on the shape and size of the functional element 640, the functional element 640 may be in a flat state. With the design, the distribution of particles 610 within the mold is ensured to be as uniform as possible. Thus, it may be possible to use more than two openings to fill the mold and / or to position the openings in a desired way. It may be advantageous to change the position.

[0100] Optionally, the method 600 may further include moving a stamp 630 toward the negative mold 620. The method further includes a step 605 of compressing the particles 610 packed in the mold. The result of this compression is shown diagrammatically in the lower part of FIG. 6. This compression 605 causes the foamed material to The density of the plurality of particles 610, and therefore the softening point produced using the method described above, This step increases the density of the shock absorber. In addition, this step serves to reduce the thickness of the shock absorber. It can be achieved.

[0101] Additionally, the method 600 described herein may be a method of manufacture according to other aspects of the present invention. As already mentioned above in connection with the use of pressure and / or steam and / or heat This can include treating the particles 610 in the mold.

[0102] In a particularly preferred embodiment of the method 600 just described, further comprising a mold 620, 30, the wall portions of the molds 620, 630 are shaped to form the emitting portions adjacent to the wall portions as described above. a temperature at which the plurality of particles of the foamed material are at least partially melted; It can be heated.

[0103] In a further embodiment, the functional elements include, in part, those described herein. and coating a plurality of particles of foamed material in a mold with a liquid matrix material so as to form a The cushioning element is manufactured by:

[0104] In addition, the individual aspects of the manufacturing method described in this specification can be combined with each other as much as possible. Such combined methods are clearly within the subject matter of the present invention. It should be noted generally that the individual steps of the described methods are not intended to be limiting unless they are combined to achieve the desired function. It should be noted again that, insofar as they are not necessary for the manufacture of a cushioning element having Such modified methods also fall within the scope of the present invention. Cushioning element produced by an embodiment of the method and sports clothing comprising such a cushioning element also form part of the present invention.

[0105] FIG. 7 illustrates a method for producing a cushioning element according to a further embodiment of the present invention. A further variant of the method 700 is shown. In contrast to method 600, in method 700 placed a functional element 740 in the mold as shown diagrammatically in the upper portion of FIG. The mold is then filled with a plurality of randomly arranged particles 710 of the foamed material. The device 702 has at least two openings 72 between a plurality of movable parts 720, 730 of different types. In the method described herein, the mold is After filling 702 the mold is filled by moving 705 the mold parts 720, 730 towards each other. , and then closed. As a result, the randomly arranged particles 710 arranged in the mold , depending on how far these two parts 720, 730 of the mold are moved towards each other, If necessary, it is further compressed. The result of this step is shown diagrammatically in the lower part of FIG. will be done.

[0106] Also in this case, at least two openings 725 are provided to allow for possible movement of the particles 710 within the mold. To achieve as uniform a distribution as possible and to avoid as much as possible the occurrence of defects in the cushioning elements In order to achieve this, the particles 710 are arranged to surround the functional element 740 from at least two sides. It is preferable that

[0107] 10 and 11 show a further embodiment 1000 of a method for manufacturing a cushioning element, Shows 1100.

[0108] In the method 1000 generally shown in FIG. 10, first, in an optional step, a function An element 1040 is placed in the mold. The mold shown in FIG. In a further step, the mold is formed by removing the seed in the movable stamp 1020. The foamed material 1010 is filled through two or more openings at different locations. After filling, Then, the opening used to perform the filling 1010 is preferably closed. In a step, the stamp 1020 is moved further toward the negative mold 1030, The mold can then be closed, thereby sealing the foamed material disposed within the mold. A compression of the plurality of particles of the foamed material is then achieved. The particles may be subjected to, for example, further pressure / steam / heat treatment etc., on one of the walls of the mould. The part may be heated, and so on.

[0109] In the method 1100 generally shown in FIG. 11, first, in an optional step, a function An element 1140 is also placed in the mold. However, the mold in the example shown in FIG. (or even more) movable stamps 1120, 1125, which are The mold may include one or more stationary portions 1130 and 1135. In this case, the mold is inserted, for example, through an opening in the movable stamp 1120, 1125. It is also possible to fill the material with particles 1110 made of a foamed material. In a further embodiment of the method according to the invention and as described herein, e.g. For example, the lower stamp 1125 is first moved further outward from the mold, and then the stamp is inserted from above into the mold. It is also possible to fill the mold with particles. This eliminates the need to convert the mold at first, e.g. , since it does not require a filling hole and therefore allows filling with particles from below as well The functional element 1140 to be placed near the bottom surface of the sole to be manufactured is Once the mold is filled in this way, the lower stamp 112 5 continues upwards, i.e., until it assumes its final position relative to the functional element 1140. In a preferred embodiment, the lower stamp and the functional element are then moved into 1140, the excess particles of foamed material that may be located between the By loading the lower stamp 1125, the The mold can then be further filled and / or closed, and the cushioning element is Multiple runs can be made as described above. Thus, the schematic diagram of FIG. The methods discussed herein do not involve the need to convert the machines used for production. It is possible to produce cushioning elements in combination with many different designs of functional elements without do.

[0110] In a preferred embodiment of the above-mentioned methods 600, 700, 1000, 1100, The functional elements 640, 740, 1040, 1140 are preferably made of a foil, particularly preferably a thermoplastic foil. The functional elements 640, 74 are provided as such foils. 0, 1040, and 1140 have a particular effect on the surface characteristics and dimensional stability of the cushioning element. It can be used to exert an effect.

[0111] For this purpose, the foil can on the one hand be externally exposed, e.g. for optical design purposes. and surrounding the cushioning element in the cushioning element, e.g., for the purpose of improving stability. In relation to the other functional elements 640, 740, 1040, 1140 described above, As previously mentioned, the foil may be inserted into the mould. Alternatively, the foil may be attached to the surface of the mould. It is also possible to insert the mold into the mold so that it fits snugly against the The pellets can be deep-drawn prior to insertion into the mold. In this case, the pellets , poured into a kind of foil shell, so that the foil is present in the finished cushioning element. In some cases, it encloses the cushioning element.

[0112] Furthermore, it is possible to combine both variants, i.e. using the foil as a cover for the cushioning element. It can be used as a functional element within a cushioning element as well as in a cushioning material.

[0113] In particular, the foil may provide a closed surface structure for the cushioning element. This may improve the durability of the cushioning element. Foils can also be useful for enhancing durability or for decorative purposes, e.g. When the cushioning element is used in the sole of a shoe, the cushioning is provided during use, such as during walking. It also serves as a "functional skin" that controls the movement and expansion of the foamed material of the element. The foil may also be waterproof, e.g. comprising a cushioning element with such a foil. The membrane may be a breathable membrane that prevents water from entering shoes or clothing that are worn.

[0114] The foil may be, for example, in order to enclose the foamed material of the cushioning element in certain areas. Therefore, to limit the expansion and / or movement of the foamed material in that area. , which is desirable in areas where high stability is important. It can become something.

[0115] On the other hand, the foil, as will be explained in more detail shortly, can be used for example in the sole of the shoe. In the toe area, for example, the high energy recovery capacity of foamed materials can be advantageously utilized. The foamed material is allowed to move and expand to a greater extent in areas where it is to be used. It is also possible to use it to create a "free" area where

[0116] FIG. 12 illustrates a variation 1200 of the embodiment of the method 600 of the present invention shown in FIG. All of the descriptions and discussion provided in relation to the embodiment 1200 shown in FIG. The same applies.

[0117] As discussed above, the functional element 640 of FIG. 6 may comprise a foil 1240. Additionally, the foil 1240 may be made of a second foamed material, as shown in FIG. A container 1240 or “bag” containing a plurality of randomly arranged particles 1245 is shown. It is possible for the software to be provided as a "package."

[0118] Any of the functional elements 640, 740, 1040, 1140 described herein may A foil 1240, in particular a plurality of randomly arranged foils made of a second foamed material. a foil 1240 serving as a container 1240 for containing particles 1245 of It is explicitly stated here that this is possible.

[0119] Moreover, such containers are intended to be within the scope of the present disclosure even if not expressly stated. It may be used with any embodiment or aspect of the present invention as understood or contemplated by one of ordinary skill in the art. This may also be the case.

[0120] The second foamed material is the same as the foamed material of the cushioning element described above. However, the second foamed material may be The material can also be different from the foamed material. Possible materials for the plurality of particles 1245 include the plurality of particles 110 made of foamed materials. , 210, 510, 610, 710, 1010, and 1110 Fees are included.

[0121] Such a container 1240 allows the cushioning element to be assembled without the need for dedicated molds 620, 630. A plurality of differently shaped regions of the second foamed material are randomly arranged in the The container 1245 can be, for example, a container having a preset shape. This pre-shaping can provide particles 1245 within the cushioning element. The placement and shape of the regions is controlled. In particular, this allows for a simple manufacturing process. A plurality of randomly arranged particles 1245 of a second foamed material are disposed within the impact element. This also makes it possible to place the device on the foot of a person wearing the shoe, for example. Inlets / inserts that provide particularly beneficial energy recovery, cushioning, or stability, etc. For example, the sole may have an inlet or insert in the forefoot or heel area. become.

[0122] The foil 1240 forming the container 1240 is made of a second foamed material. The particle 1245 is preferably made of a foamed material of the cushioning element together with a plurality of particles 610. Then, in the molds 620, 630, the molds are treated with pressure and / or heat and / or steam. For example, the material may be porous, may have perforations, or may have a mesh-like structure, so that the material can be or may be permeable to heat and / or vapor in a different manner. In this case, the foil 1240 and the possible opening of the container 1240 are covered with a second foamed a plurality of particles 1245 of a foamed material and preferably further comprising a foamed material; Small enough that particles 610 are unable to pass through those openings. It should be.

[0123] In such a process, the foil 1240 decomposes to form a foamed material. and a plurality of randomly arranged particles 610 of a second material. A plurality of particles 1245 may be directly bonded to each other. However, the foil 1240 may also act as a binder. 0 may remain within the cushioning element. Thus, the foil 1240 is a foamed material and a plurality of particles 1245 made of a second expanded material. In this case, the foil 1240 may also serve as a bridge between the For example, it may show further functionality, such as acting as a "functional skin" as mentioned above. good.

[0124] For example, a plurality of randomly arranged particles 1245 of a second foamed material. The density is greater than the density of the randomly arranged particles 610 of the foamed material. a foil 124 surrounding a plurality of particles 1245 made of a second foamed material; 0 by also restricting the movement and expansion of the second foamed material within the cushioning element. In this way, it is possible for a highly stable region to be formed. 20, 630 by being compressed under pressure into the container 1240 , higher densities can be achieved.

[0125] Also, a plurality of randomly arranged particles 1245 of a second foamed material are densely packed. The density is lower than the density of the randomly arranged particles 610 of the foamed material. The particles 1245 may be, for example, in a container 1 inserted in the mold 620, 630. 240, a lower density can be achieved. Areas of essentially any desired shape and / or location within the element may be used to provide cushioning. In this region, a plurality of particles of the second expanded material may be formed. 1245 is “liberated” to allow for more significant movement and This allows for inflation and high energy return to the user, for example when taking a step while walking.

[0126] In another embodiment, the functional element 640, 470 is made of a foamed material. In particular, the functional element does not include a plurality of particles of foamed material. This is because, for example, the buffer element is then replaced by a functional element. There is the possibility of removing or replacing functional elements, e.g. electronic elements that provide a power supply. This is advantageous for functional elements because they are present in the , a reinforcing element or an outsole element or something similar.

[0127] As previously mentioned, the characteristics of the cushioning element may be combined with various aspects of the methods described herein. Depending on the combination and / or each process parameter (e.g. pressure, duration, temperature, type of section A number of different configurations may be used, depending on the variation in the number of It is possible for the impact to be felt in a variety of ways.

[0128] According to a further aspect of the invention, a method is provided comprising the steps of: The characteristics of the cushioning element produced by the method are determined by the appropriate selection of the particles of the foamed material. This means that it is possible to be further affected.

[0129] differing in particular in material and / or size and / or density and / or color A plurality of particles of an expanded material including a mixture of at least two types of particles, In particular, the following materials may be used in the methods described herein: One or more of the following: foamed ethylene vinyl acetate, foamed thermoplastic urethane, Foamed polypropylene, foamed polyamide, foamed polyether block amide, foamed polyoxy Methylene, expanded polystyrene, expanded polyethylene, expanded polyoxyethylene, expanded ethylene The propylene diene monomer can be considered as a raw material.
