Definitions
- the present invention relates to a gymnastic band made of a flexible, elastic material for strengthening the muscles, ligaments and tendons of the movement apparatus, which is used in particular in medical therapy.
- Conventional exercise bands are made of rubber (rubber) or latex.
- latex has a number of disadvantages. It is known that some people are allergic to latex, which is the case when using latex-containing exercise bands, e.g. local skin irritation, such as eczema. Furthermore, latex has a rather sticky consistency and is therefore frequently dusted with powder or the like in order to prevent the gymnastic band from sticking together. Powdering latex is very harmful from a health point of view, since the powder itself can act as an allergy-causing substance on the skin.
- the powder when the exercise band is used, the powder easily passes into the air and, often loaded with latex particles, can be inhaled into the lungs of the user, so that powder and / or latex in the lungs can trigger systemic allergic reactions.
- Another disadvantage of latex is that many people find its smell unpleasant.
- latex When pulling apart or stretching, latex is further characterized by a non-linear force-displacement characteristic which, as is known by medical therapists, leads to only auxotonic strain on the muscles, that is to say that with increasing stretching of the gymnastic band, that of the gymnastic band Elongation opposite tensile resistance increases disproportionately.
- this is not always desirable because it limits the amount of movement of Joint parts can be severely restricted when the exercise band is stretched if the muscle strength is insufficient to stretch the exercise band sufficiently.
- a gymnastic band with a lower tensile resistance In order to ensure a sufficient range of motion for weaker muscles, a gymnastic band with a lower tensile resistance must therefore be selected, which for the same material has so far only been produced by varying the thickness of the gymnastic band or by changing the Shore hardness of the rubber-like material. Conversely, an exercise band with a tensile resistance that is too low for a particular muscle can easily get small tears, which can lead to a sudden and sudden tearing of the exercise band, which in turn can lead to injuries.
- the object of the present invention is to provide an exercise band with which the disadvantages mentioned at the outset can be avoided.
- the present invention relates to an exercise band for strengthening muscles, ligaments and tendons of the musculoskeletal system, which is made from a flexible, elastic band material.
- the exercise band comprises at least one (preferably at room temperature) thermoplastic elastomeric material (a) and a further material (b) that is different from the thermoplastic elastomer.
- the material (b) comprises silicone or teflon.
- the materials (a) and (b) are preferably present in different layers.
- At least one layer comprises silicone or Teflon and another layer of the thermoplastic elastomer different from silicone or Teflon.
- the exercise band comprises at least one thermoplastic elastomeric material and has grooves on at least one side (i.e. on one or both sides) in the form of grooves along the longitudinal direction (along the direction of stretch) of the band.
- the gymnastic band is made from a band material which comprises at least one - preferably at room temperature (i.e. at approximately 21 ° C.) - elastic thermoplastics or thermoplastic elastomers, hereinafter referred to as thermoplastic elastomer or thermoplastic elastomer material.
- thermoplastic elastomers are: e.g .: styrene block copolymers (TPE-S), SEBS, thermoplastic copolyesters, polyether esters (TPE-E), thermoplastic polyurethanes (TPE-U), polyether polyamide block copolymers (TPE-A).
- TPE-S styrene block copolymers
- SEBS SEBS
- thermoplastic copolyesters polyether esters
- TPE-U thermoplastic polyurethanes
- TPE-A polyether polyamide block copolymers
- Thermoplastics generally have a lower elasticity than elastomers. According to the invention, however, thermoplastics can also be used which are provided with elastic properties by adding appropriate materials known per se, such as fillers and / or plasticizers.
- the thermoplastic elastomers used according to the invention fillers and / or plasticizers such as waxes, aerosil (highly disperse silica), dyes, lubricants (oleic acid amide, erucamide), antioxidants (hydroquinones, pyrocatechols, gallates etc.) or barium sulfate can generally be added.
- thermoplastic elastomer advantageously makes it possible to dispense with the use of latex which triggers allergies or the powder applied thereon. Since thermoplastic elastomers do not age as quickly as latex, there is also the advantage that the exercise band is subject to a considerably lower risk of tearing if it is overstretched, so that injuries can be avoided.
- thermoplastic elastomers can be mixed with other, in particular elastic, materials (preferably with crosslinked materials).
- Preferred here are e.g. addition or condensation crosslinked silicones (especially under platinum catalysis addition crosslinked silicones), EADM rubber, NBR rubber and other irreversibly crosslinkable materials.
- the exercise band is constructed in layers and has at least two layers made of different materials.
- Such a layered structure of the gymnastic band enables the stretch properties or the tensile resistance of the gymnastic band to be influenced in a particularly simple manner by selecting suitable layer materials.
- This can also increase the chemical resistance of the thermoplastic elastomeric materials to oils and solvents (such as those found in nail polish removers or Disinfectants are available) and they are also stabilized against elevated temperatures.
- a layer made of at least one thermoplastic elastomer is particularly advantageous, which is combined, for example, with a layer of Teflon or a layer made of silicone and / or mixtures thereof.
- the thermoplastic elastomer is preferably coated on both surfaces with a layer of another material (in particular silicone or Teflon). It is also possible to coat one side of the band with a material, for example silicone, and the other side of the band with another material, for example Teflon.
- the thermoplastic elastomer is particularly preferably completely covered or covered with a layer of another material (preferably silicone and / or Teflon). This can be done, for example, by coating in an immersion bath or during extrusion. This coating improves the chemical resistance and thus the durability of the strip material.
- the tape can thus also be disinfected more easily in order to avoid the risk of contact infection by users.
- the layer which contains a thermoplastic elastomer preferably has a layer thickness of 50 ⁇ m to 2 mm, particularly preferably from 100 ⁇ m to 1 mm and in particular from 200 ⁇ m to 600 ⁇ m.
- the further layer (s) can have a thickness of 5 ⁇ m to 2 mm; If the layer containing the thermoplastic elastomer is coated with Teflon, the Teflon layer preferably has a thickness of 10 ⁇ m to 15 ⁇ m.
- the tape comprises a first layer which contains a thermoplastic elastomer and a second layer which contains silicone, the layer thickness of the second layer is preferably 5 to 100% of the layer thickness of the first layer.
- the gymnastics band of the present invention has an absorbent surface on one or both sides, which is designed in particular as flocking with absorbent fibers or as an applied fleece.
- absorbent fibers are cellulose, synthetic fibers or viscose.
- the absorbent surface can be produced, for example, by electrostatic flocking or by pressing a fleece onto the hot thermoplastic elastomer (for example after extrusion).
- the absorbent surface is preferably not applied to the thermoplastic elastomer with the aid of an adhesive.
- the tape material can only comprise a thermoplastic elastomer or a mixture of thermoplastic elastomers.
- the gymnastic band of the present invention comprises in one layer a mixture of at least one thermoplastic elastomer (a) and a material (b) different from a thermoplastic elastomer.
- a weight ratio (a): (b) of 30:70 to 95: 5% by weight is preferred, in particular 85:15 b ⁇ s 95: 5% by weight.
- silicone in particular addition- or condensation-crosslinked silicones
- Teflon acrylonitrile-buitadiene rubber
- EPDM rubber e.g. Santoprene
- polyurethanes polystyrenes and other irreversibly crosslinkable materials form three-dimensional structure.
- silicone for example, refers to higher molecular weight connections, with a three-dimensional structure alternately composed of silicon and oxygen atoms. Silicon atoms in Silicones that do not reach their electron octet through the formation of bonds to oxygen are saturated with organic residues R.
- the framework can be linear or highly branched.
- One example is polymeric compounds of repeating units of the general formula R 2 SiO, where the radicals R can be the same or different and are conventional radicals known to those skilled in the art. Examples of the radicals R are hydrogen, methyl, vinyl or phenyl groups.
- the associated "weakening" of the band material allows the tensile resistance of the gymnastic band to be reduced in an extremely advantageous manner when it is stretched.
- a certain, desired force-displacement characteristic can be imparted to the gymnastic band as it is stretched by the surface structure.
- the surface structure can be used to impart a linear force-displacement characteristic to the gymnastics band.
- the preferably provided grooves also result in the contact area of the surface plane of the exercise band being reduced. Since thermoplastic elastomers can also have sticky properties, the grooves can advantageously also prevent the gymnastic band from sticking together by reducing the surface level that acts as sticky.
- At least one of the two surfaces of the band has a multiplicity (at least 2) of depressions (grooves) which extend from the surface plane of one side in the direction of the opposite side.
- These depressions can each have a rectangular, in particular square or round, cross section perpendicular to the surface plane.
- the depressions (grooves) advantageously run along the stretching direction of the band.
- the exercise band can have a honeycomb surface structure.
- a honeycomb surface structure gives the tape properties similar to that of a fabric, i.e. that it has a high tensile strength with high flexibility and low tendency to bulge and fold.
- This is achieved by the "bridges" of a gymnastic band designed in this way between the honeycombs.
- the webs advantageously extend at right angles to one another, so that the depressions in the surface plane have a rectangular, in particular square, cross section. This gives the band an essentially uniform stretching behavior.
- the depressions can each have a hexagonal, in particular equilateral, hexagonal cross section in the surface plane.
- the two surfaces or the surface structures of the gymnastic band according to the invention can be the same or different.
- the wells can, for example, by. Embossing of the gymnastics band produced.
- the gymnastic band according to the invention comprises at least one longitudinal reinforcement strip made of a material different from the band material in order to further reduce the risk of sudden tearing.
- This preferably tear-resistant reinforcement strip can e.g. have a length corresponding to the length of the tape at maximum stretch; e.g. be arranged in a zigzag shape or in loops in or on the belt.
- the exercise band of the present invention preferably includes an indicator that indicates the amount of force applied.
- the indicator can e.g. a color indicator or a strain gauge, as used in scales.
- the indicator can be made of a piezoelectric material. The use of this indicator advantageously allows the force applied to be controlled and thus enables dosed therapy.
- the gymnastic band according to the invention can, as is also usual with conventional latex gymnastic bands, be produced by melting or subsequent solidification. According to the invention, however, it is preferred to produce the gymnastic band by means of the much cheaper extrusion.
- the strip material should preferably be an extrudable material.
- a strip material which, when stretched in the strip direction, is essentially one without the use of additives has linear force-displacement characteristic.
- the tensile resistance increases substantially proportionally with the stretching of the gymnastic band; the tape therefore preferably essentially fulfills Hooke's law.
- a band material with such behavior can be used in a particularly advantageous manner to strengthen muscles, ligaments and tendons of the musculoskeletal system: as already mentioned above, in contrast to conventional gymnastics bands, it enables a greater range of motion of joint parts, which in particular increases the mobility of joints under load can be trained.
- the lower increase in tensile resistance compared to conventional gymnastic bands with stretching of the gymnastic band avoids the risk of undesired overloading of the user's musculoskeletal system, for example in the case of previously damaged or weak tendons, such as after a tendon tear.
- the course of therapy can also be favorably influenced.
- the ends of the gymnastic band according to the invention can be designed as loops which e.g. can be produced by fusing.
- the ends of the tape can be joined together (e.g. by fusing the ends) to create an endless loop.
- the gymnastic band can be provided with handles at the ends.
- the gymnastic band according to the invention has excellent properties with regard to tear strength and stretching behavior.
- the exercise band can be manufactured inexpensively by extrusion. The invention will now be illustrated using exemplary embodiments, reference being made to FIG. 1.
- Fig. 1 shows a schematic representation in cross section in the band direction of an embodiment of the exercise band according to the invention.
- Fig. 1 shows a section of a gymnastic band according to the invention in cross section in the direction of the band, the cut being made perpendicular to the band plane.
- the gymnastics band 1 is made of the thermoplastic elastomer TPE-S and manufactured by extrusion. Both surfaces of the exercise band are provided with a surface structure. The surfaces have a multiplicity of depressions 4 which, starting from the surface planes 2, 3 of the two sides, extend in the direction of the opposite side. The depressions 4 have a groove shape, the grooves extending along the band direction of the exercise band 1. The grooves 4 are formed by the grooves 4 adjacent elevations 5.
- the surface structures of the two sides of the exercise band were created by embossing the exercise band produced by extrusion. The surface structure in the form of grooves allows a targeted weakening of the tensile resistance of the gymnastic band 1 when stretched.

Description
Gymnastik and Gymnastics and
Die vorliegende Erfindung betrifft ein Gymnastikband aus einem flexiblen, elastischen Material zur Stärkung von Muskulatur, Bändern und Sehnen des Bewegrungsapparats, welches insbesondere in der medizinischen Therapie eingesetzt wird.The present invention relates to a gymnastic band made of a flexible, elastic material for strengthening the muscles, ligaments and tendons of the movement apparatus, which is used in particular in medical therapy.
Herkömmliche Gymnastikbänder sind aus Gummi (Kautschuk) bzw. Latex gefertigt. Latex ist edoch mit einer Reihe von Nachteilen verbunden. So ist es bekannt, dass manche Menschen auf Latex allergisch reagieren was bei der Verwendung von Latex- haltigen Gymnastikbänden z.B. zu lokalen Hautirriationen, wie Ekzemen führen kann. Weiterhin hat Latex eine eher klebrige Konsistenz und wird deshalb, um ein Zusammenkleben des Gymnastikbands zu vermeiden, häufig mit Puder oder dergleichen bestäubt. Eine Puderung von Latex ist jedoch in gesundheitlicher Hinsicht sehr bedenklich, da der Puder selbst als Allergie auslösender Stoff auf der Haut wirken kann. Zudem tritt der Puder bei Einsatz des Gymnastikbands leicht in die Luft über und kann, oft mit Latexpartikeln beladen, in die Lunge des Anwenders eingeatmet werden, so dass Puder und/oder Latex in der Lunge systemische allergische Reaktionen auslösen können. Ein weiterer Nachteil von Latex ist, dass sein Geruch von vielen Menschen als unangenehm empfunden wird.Conventional exercise bands are made of rubber (rubber) or latex. However, latex has a number of disadvantages. It is known that some people are allergic to latex, which is the case when using latex-containing exercise bands, e.g. local skin irritation, such as eczema. Furthermore, latex has a rather sticky consistency and is therefore frequently dusted with powder or the like in order to prevent the gymnastic band from sticking together. Powdering latex is very harmful from a health point of view, since the powder itself can act as an allergy-causing substance on the skin. In addition, when the exercise band is used, the powder easily passes into the air and, often loaded with latex particles, can be inhaled into the lungs of the user, so that powder and / or latex in the lungs can trigger systemic allergic reactions. Another disadvantage of latex is that many people find its smell unpleasant.
Beim Auseinanderziehen bzw. Dehnen zeichnet sich Latex ferner durch eine nicht-lineare Kraft-Weg-Kennlinie aus, welche, wie medizinischen Therapeuten bekannt ist, zu einer lediglich auxotonen Belastung der Muskulatur führt, d.h. dass mit zunehmender Dehnung des Gyrnriastikbands der von dem Gymnastikband der Dehnung entgegengesetzte Zugwiderstand in überproportionaler Weise ansteigt. Dies ist jedoch nicht immer erwünscht, da hierdurch der Umfang der Bewegung von
Gelenkteilen bei einer Dehnung des Gymnastikbands stark eingeschränkt sein kann, wenn die Muskelkraft nicht ausreicht, das Gymnastikband hinreichend zu dehnen.When pulling apart or stretching, latex is further characterized by a non-linear force-displacement characteristic which, as is known by medical therapists, leads to only auxotonic strain on the muscles, that is to say that with increasing stretching of the gymnastic band, that of the gymnastic band Elongation opposite tensile resistance increases disproportionately. However, this is not always desirable because it limits the amount of movement of Joint parts can be severely restricted when the exercise band is stretched if the muscle strength is insufficient to stretch the exercise band sufficiently.
Um bei schwächeren Muskeln einen ausreichenden Bewegungsumfang zu gewährleisten, muss deshalb ein Gymnastikband mit einem geringeren Zugwiderstand gewählt werden, welches bei gleichem Material bislang lediglich durch eine Dickenvariation des Gymnastikbands bzw. durch Ändern der Shore-Härte des gummiartigen Materials hergestellt wird. Umgekehrt kann ein Gymnastikband mit einem für einen bestimmten Muskel zu geringen Zugwiderstand leicht kleine Risse bekommen, welche zum einen plötzlichen und schlagartigen Durchreißen des Gymnastikbands führen können, was wiederum zu Verletzungen führen kann.In order to ensure a sufficient range of motion for weaker muscles, a gymnastic band with a lower tensile resistance must therefore be selected, which for the same material has so far only been produced by varying the thickness of the gymnastic band or by changing the Shore hardness of the rubber-like material. Conversely, an exercise band with a tensile resistance that is too low for a particular muscle can easily get small tears, which can lead to a sudden and sudden tearing of the exercise band, which in turn can lead to injuries.
Die Aufgabe der vorliegenden Erfindung liegt darin, ein Gymnastikband zur Verfügung zu stellen, mit welchem die eingangs genannten Nachteile vermieden werden können.The object of the present invention is to provide an exercise band with which the disadvantages mentioned at the outset can be avoided.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1, 2 oder 4 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the features of claims 1, 2 or 4. Advantageous embodiments of the invention are specified in the subclaims.
Die vorliegende Erfindung betrifft ein Gymnastikband zur Stärkung von Muskulatur, Bändern und Sehnen des Bewegungs- apparats, welches aus einem flexiblen, elastischen Bandmaterial gefertigt ist. Das Gymnastikband umfasst wenigstens ein (bevorzugt bei Raumtemperatur) thermoplastisches elastomeres Material (a) und ein weiteres, von dem thermoplastischen Elastomeren verschiedenes, Material (b) .The present invention relates to an exercise band for strengthening muscles, ligaments and tendons of the musculoskeletal system, which is made from a flexible, elastic band material. The exercise band comprises at least one (preferably at room temperature) thermoplastic elastomeric material (a) and a further material (b) that is different from the thermoplastic elastomer.
Insbesondere umfasst das Material (b) Silikon oder Teflon.
Bevorzugt liegen die Materialien (a) und (b) in verschiedenen Schichten vor.In particular, the material (b) comprises silicone or teflon. The materials (a) and (b) are preferably present in different layers.
Weiter bevorzugt umfasst dabei wenigstens eine Schicht Silikon oder Teflon und eine andere Schicht des von Silikon oder Teflon verschiedenen thermoplastischen Elastomer.More preferably, at least one layer comprises silicone or Teflon and another layer of the thermoplastic elastomer different from silicone or Teflon.
Alternativ oder zusätzlich umfasst das Gymnastikband wenigstens ein thermoplastisches elastomeres Material und weist auf wenigstens einer Seite (d.h. auf einer oder auf beiden Seiten) Vertiefungen in Form von Rillen entlang der Längsrichtung (längs zur Dehnungsrichtung) des Bandes auf.Alternatively or additionally, the exercise band comprises at least one thermoplastic elastomeric material and has grooves on at least one side (i.e. on one or both sides) in the form of grooves along the longitudinal direction (along the direction of stretch) of the band.
Erfindungsgemäß ist das Gymnastikband aus einem Bandmaterial gefertigt, welches wenigstens einen - bevorzugt bei Raumtemperatur (d. h. bei z. B. etwa 21°C) - elastischen Thermoplasten oder thermoplastischen Elastomeren, im Weiteren thermoplastischer Elastomer bzw. thermoplastisches elastomeres Material genannt, umfasst.According to the invention, the gymnastic band is made from a band material which comprises at least one - preferably at room temperature (i.e. at approximately 21 ° C.) - elastic thermoplastics or thermoplastic elastomers, hereinafter referred to as thermoplastic elastomer or thermoplastic elastomer material.
Beispiele für thermoplastische Elastomere sind: z.B.: Styrol- blockcopolymere (TPE-S) , SEBS, thermoplastische Copolyester, Polyetherester (TPE-E) , thermoplastische Polyurethane (TPE-U) , Polyether-Polya id Blockcopolymere (TPE-A) . Derartige thermoplastische Elastomere sind an sich, d.h. auch ohne Zusatz weiterer Materialien, thermoplastisch und elastisch.Examples of thermoplastic elastomers are: e.g .: styrene block copolymers (TPE-S), SEBS, thermoplastic copolyesters, polyether esters (TPE-E), thermoplastic polyurethanes (TPE-U), polyether polyamide block copolymers (TPE-A). Such thermoplastic elastomers are in themselves, i.e. even without the addition of other materials, thermoplastic and elastic.
Thermoplaste weisen grundsätzlich eine geringere Elastizität auf als Elastomere. Erfindungsgemäß können jedoch auch Thermoplaste eingesetzt werden, die durch Zugabe entsprechender an sich bekannter Materialien, wie z.B. Füllstoffe und/oder Weichmacher, mit elastischen Eigenschaften versehen werden. Die erfindungsgemäß eingesetzten thermoplastischen Elastomere
können allgemein mit Füllstoffen und/oder Weichmachern wie z.B. Wachsen, Aerosil (hochdisperse Kieselsäure), Farbstoffen, Gleitmitteln (Ölsäureamid, Erucamid) , Antioxidantien (Hydrochinone, Brenzcatechine, Gallate etc.) oder Bariumsulfat versetzt werden.Thermoplastics generally have a lower elasticity than elastomers. According to the invention, however, thermoplastics can also be used which are provided with elastic properties by adding appropriate materials known per se, such as fillers and / or plasticizers. The thermoplastic elastomers used according to the invention fillers and / or plasticizers such as waxes, aerosil (highly disperse silica), dyes, lubricants (oleic acid amide, erucamide), antioxidants (hydroquinones, pyrocatechols, gallates etc.) or barium sulfate can generally be added.
Die Verwendung eines thermoplastischen Elastomeren ermöglicht in vorteilhafter Weise, auf die Verwendung von Allergie auslösendem Latex bzw. den darauf aufgebrachten Puder zu verzichten. Da thermoplastische Elastomere nicht so schnell altern wie Latex, ergibt sich zudem der Vorteil, dass das Gymnastikband einer erheblich geringeren Gefahr des Einreißens bei einer Überdehnung unterliegt, so dass Verletzungen vermieden werden können.The use of a thermoplastic elastomer advantageously makes it possible to dispense with the use of latex which triggers allergies or the powder applied thereon. Since thermoplastic elastomers do not age as quickly as latex, there is also the advantage that the exercise band is subject to a considerably lower risk of tearing if it is overstretched, so that injuries can be avoided.
Erfindungsgemäß können die thermoplastischen Elastomere mit anderen, insbesondere elastischen, Materialien (bevorzugt mit vernetzten Materialien) gemischt werden. Bevorzugt sind hier z.B. additions- oder kondensationsvernetzte Silikone (insbesondere unter Platinkatalyse additionsvernetzte Silikone) , EADM Kautschuk, NBR Kautschuk und andere irreversibel vernetzbare Materialien.According to the invention, the thermoplastic elastomers can be mixed with other, in particular elastic, materials (preferably with crosslinked materials). Preferred here are e.g. addition or condensation crosslinked silicones (especially under platinum catalysis addition crosslinked silicones), EADM rubber, NBR rubber and other irreversibly crosslinkable materials.
Bei einer weiteren vorteilhaften Ausführungsform der Erfindung ist das Gymnastikband schichtenförmig aufgebaut und weist wenigstens zwei Schichten aus verschiedenen Materialien auf. Ein solcher schichtenförmiger Aufbau des Gymnastikbands ermöglicht in besonders einfacher Weise durch Wahl geeigneter Schichtmaterialien, die Dehneigenschaften bzw. den Zugwiderstand des Gymnastikbands in gewünschter Weise zu beeinflussen. Auch können dadurch die chemische Resistenz der thermoplastischen elastomeren Materialien gegenüber Ölen und Lösungsmitteln (wie sie z.B. in Nagellackentfernern oder
Desinfektionsmitteln vorhanden sind) verbessert und sie außerdem gegenüber erhöhten Temperaturen stabilisiert werden. Vorteilhaft ist insbesondere eine Schicht aus zumindest einem thermoplastischen Elastomer, die z.B. mit einer Schicht Teflon oder einer Schicht aus Silikon und/oder Gemischen davon kombiniert ist. Bevorzugt ist das thermoplastische Elastomer auf beiden Oberflächen mit einer Schicht aus einem anderen Material (insbesondere Silikon oder Teflon) beschichtet. Auch ist es möglich, eine Seite des Bandes mit einem Material, z.B. Silikon, und die andere Seite des Bandes mit einem weiteren Material, z.B. Teflon, zu beschichten. Besonders bevorzugt ist das thermoplastische Elastomer komplett mit einer Schicht aus einem anderen Material (bevorzugt Silikon und/oder Teflon) überzogen bzw. umhüllt. Dies kann z.B. durch Beschichtung in einem Tauchbad oder beim Extrudieren erfolgen. Durch diese Beschichtung verbessert sich die chemische Resistenz und damit die Haltbarkeit des Bandmaterials. Das Band kann somit auch leichter desinfiziert werden, um die Gefahr einer Kontaktinfektion von Anwendern zu vermeiden.In a further advantageous embodiment of the invention, the exercise band is constructed in layers and has at least two layers made of different materials. Such a layered structure of the gymnastic band enables the stretch properties or the tensile resistance of the gymnastic band to be influenced in a particularly simple manner by selecting suitable layer materials. This can also increase the chemical resistance of the thermoplastic elastomeric materials to oils and solvents (such as those found in nail polish removers or Disinfectants are available) and they are also stabilized against elevated temperatures. A layer made of at least one thermoplastic elastomer is particularly advantageous, which is combined, for example, with a layer of Teflon or a layer made of silicone and / or mixtures thereof. The thermoplastic elastomer is preferably coated on both surfaces with a layer of another material (in particular silicone or Teflon). It is also possible to coat one side of the band with a material, for example silicone, and the other side of the band with another material, for example Teflon. The thermoplastic elastomer is particularly preferably completely covered or covered with a layer of another material (preferably silicone and / or Teflon). This can be done, for example, by coating in an immersion bath or during extrusion. This coating improves the chemical resistance and thus the durability of the strip material. The tape can thus also be disinfected more easily in order to avoid the risk of contact infection by users.
Bevorzugt weist die Schicht, die ein thermoplastisches Elastomer enthält, eine Schichtdicke von 50 μm bis 2 mm auf, besonders bevorzugt von 100 μm bis 1 mm und insbesondere von 200μm bis 600μm. Die weitere (n) Schicht (en) kann/können eine Dicke von 5 μm bis 2 mm aufweisen; ist die das thermoplastische Elastomer enthaltende Schicht mit Teflon beschichtet, weist die Teflonschicht bevorzugt eine Dicke von 10 μm bis 15 μm auf. Wenn das Band eine erste Schicht umfasst, die ein thermoplastisches Elastomer enthält, sowie eine zweite Schicht, die Silikon enthält, so beträgt die Schichtdicke der zweiten Schicht bevorzugt 5 bis 100% der Schichtdicke der ersten Schicht.
Weiter bevorzugt weist das Gymnastikband der vorliegenden Erfindung auf einer oder auf beiden Seiten eine saugfähάge Oberfläche auf, die insbesondere als Beflockung mit saugfähigen Fasern oder als aufgebrachter Vlies gestaltet ist. Beispiele für saugfähige Fasern sind Cellulose, Kunstfasern oder Viskose. Die saugfähige Oberfläche kann beispielsweise durch elektrostatische Beflockung oder durch Aufpressen eines Vlieses auf den heißen thermoplastischen Elastomer (z.B. nach dem Extrudieren) hergestellt werden. Bevorzugt wird die saugfähige Oberfläche nicht mit Hilfe eines Klebstoffs auf den thermoplastischen Elastomer aufgebracht.The layer which contains a thermoplastic elastomer preferably has a layer thickness of 50 μm to 2 mm, particularly preferably from 100 μm to 1 mm and in particular from 200 μm to 600 μm. The further layer (s) can have a thickness of 5 μm to 2 mm; If the layer containing the thermoplastic elastomer is coated with Teflon, the Teflon layer preferably has a thickness of 10 μm to 15 μm. If the tape comprises a first layer which contains a thermoplastic elastomer and a second layer which contains silicone, the layer thickness of the second layer is preferably 5 to 100% of the layer thickness of the first layer. More preferably, the gymnastics band of the present invention has an absorbent surface on one or both sides, which is designed in particular as flocking with absorbent fibers or as an applied fleece. Examples of absorbent fibers are cellulose, synthetic fibers or viscose. The absorbent surface can be produced, for example, by electrostatic flocking or by pressing a fleece onto the hot thermoplastic elastomer (for example after extrusion). The absorbent surface is preferably not applied to the thermoplastic elastomer with the aid of an adhesive.
Das Bandmaterial kann lediglich einen thermoplastischen Elastomeren oder eine Mischung von thermoplastischen Elastomeren umfassen.The tape material can only comprise a thermoplastic elastomer or a mixture of thermoplastic elastomers.
Gemäß einer bevorzugten Ausführungsform umfasst das Gymriastik- band der vorliegenden Erfindung in einer Schicht eine M±schung aus wenigstens einem thermoplastischen Elastomeren (a) und einem von einem thermoplastischen Elastomeren verschiedenen Material (b) . Bevorzugt ist dabei ein Gewichtsverhältnis (a) : (b) von 30:70 bis 95:5 Gew.-%, insbesondere von 85:15 b±s 95:5 Gew.-%.According to a preferred embodiment, the gymnastic band of the present invention comprises in one layer a mixture of at least one thermoplastic elastomer (a) and a material (b) different from a thermoplastic elastomer. A weight ratio (a): (b) of 30:70 to 95: 5% by weight is preferred, in particular 85:15 b ± s 95: 5% by weight.
Beispiele für die genannten von Thermoplasten verschiedenen Materialien sind: Silikon (insbesondere additions- oder kondensationsvernetzte Silikone) , Teflon, Acrylnitril-Buitadien Kautschuk (NBR), EPDM Kautschuk (z. B. Santoprene) , Polyurethane, Polystyrole und andere irreversibel vernetzbare Materialien die eine dreidimensionale Struktur ausbilden. Der Ausdruck Silikon bezeichnet z.B. höhermolekulare Verbinclungen, mit einem alternierend aus Silizium- und Sauerstoff-Atomen aufgebauten dreidimensionalen Gerüst. Silizium-Atome in
Silikonen, die durch das Ausbilden von Bindungen zu Sauerstoff ihr Elektronen-Oktett nicht erreichen, werden mit organischen Resten R abgesättigt. Das Gerüst kann linear oder stark verzweigt sein. Ein Beispiel sind polymere Verbindungen aus sich wiederholenden Einheiten der allgemeinen Formel R2SiO wobei die Reste R gleich oder verschieden sein können und an sich übliche, dem Fachmann bekannte Reste sind. Beispiele für die Reste R sind Wasserstoff, Methyl, Vinyl oder Phenylgruppen .Examples of the materials mentioned other than thermoplastics are: silicone (in particular addition- or condensation-crosslinked silicones), Teflon, acrylonitrile-buitadiene rubber (NBR), EPDM rubber (e.g. Santoprene), polyurethanes, polystyrenes and other irreversibly crosslinkable materials form three-dimensional structure. The term silicone, for example, refers to higher molecular weight connections, with a three-dimensional structure alternately composed of silicon and oxygen atoms. Silicon atoms in Silicones that do not reach their electron octet through the formation of bonds to oxygen are saturated with organic residues R. The framework can be linear or highly branched. One example is polymeric compounds of repeating units of the general formula R 2 SiO, where the radicals R can be the same or different and are conventional radicals known to those skilled in the art. Examples of the radicals R are hydrogen, methyl, vinyl or phenyl groups.
Mittels der in einer bevorzugten Ausführungsform vorhandenen Rillen kann durch die damit einher gehende "Schwächung" des Bandmaterials der Zugwiderstand des Gymnastikbands bei dessen Dehnung in äußerst vorteilhafter Weise gezielt vermindert werden. Mit anderen Worten, kann durch die Olberflächen- strukturierung dem Gymnastikband bei dessen Dehnung eine bestimmte, gewünschte Kraft-Weg-Kennlinie vermittelt werden. So kann dem Gymnastikband durch die Oberflächenstrukturierung etwa eine lineare Kraft-Weg-Kennlinie vermittelt werden.By means of the grooves present in a preferred embodiment, the associated "weakening" of the band material allows the tensile resistance of the gymnastic band to be reduced in an extremely advantageous manner when it is stretched. In other words, a certain, desired force-displacement characteristic can be imparted to the gymnastic band as it is stretched by the surface structure. For example, the surface structure can be used to impart a linear force-displacement characteristic to the gymnastics band.
Die bevorzugt vorgesehenen Rillen führen zudem dazu, dass die Kontaktfläche der Oberflächenebene des Gymnastikbands verringert wird. Da thermoplastische Elastomere auch klebrige Eigenschaften aufweisen können, kann durch die Rillen in vorteilhafter Weise auch ein Verkleben des Gymnastikbands durch Verringern der klebrig wirkenden Oberflächenebene vermieden werden.The preferably provided grooves also result in the contact area of the surface plane of the exercise band being reduced. Since thermoplastic elastomers can also have sticky properties, the grooves can advantageously also prevent the gymnastic band from sticking together by reducing the surface level that acts as sticky.
Des weiteren verhindern erhöhte LängsStrukturen zwischen den Rillen bei einer im Verhältnis zu einem glatten Band vergleichbaren Kraft ein plötzliches (schlagartiges) Durchreißen des Bandes und tragen dadurch wesentlich zum Schutz des Anwenders/Patienten bei.
In einer bevorzugten Ausführungsform weist mindestens eine der beiden Oberflächen des Bandes eine Vielzahl (mindestens 2) von Vertiefungen (Rillen) auf, welche sich ausgehend von der Oberflächenebene einer Seite in Richtung der abgewandten Seite erstrecken. Diese Vertiefungen können jeweils senkrecht zur Oberflächenebene einen rechteckigen, insbesondere quadratischen oder runden Querschnitt aufweisen. Die Vertiefungen (Rillen) verlaufen vorteilhaft entlang der Dehnungsrichtung des Bands.Furthermore, increased longitudinal structures between the grooves prevent a sudden (abrupt) tearing of the band with a force comparable to a smooth band and thus contribute significantly to the protection of the user / patient. In a preferred embodiment, at least one of the two surfaces of the band has a multiplicity (at least 2) of depressions (grooves) which extend from the surface plane of one side in the direction of the opposite side. These depressions can each have a rectangular, in particular square or round, cross section perpendicular to the surface plane. The depressions (grooves) advantageously run along the stretching direction of the band.
Gemäß einer weiteren Ausführungsform kann das Gymnastikband eine wabenförmige Oberflächenstruktur aufweisen. Eine derartige Oberfläche verleiht dem Band ähnliche Eigenschaften wie sie ein Gewebe hat, d.h. dass es bei hoher Flexibilität und geringer Neigung zum Aufwölben und Faltenbilden eine hohe Reißfestigkeit aufweist. Dies wir durch die zwischen den Waben verbleibenden "Stege" eines derart gestalteten Gymnastikbands erreicht. Die Stege erstrecken sich vorteilhaft rechtwinklig zueinander, so dass die Vertiefungen in der Oberflächenebene einen rechteckigen, insbesondere quadratischen Querschnitt aufweisen. Dies verleiht dem Band ein im wesentlichen gleichmäßig ausgeprägtes Dehnverhalten. Alternativ können die Vertiefungen je in der Oberflächenebene einen sechseckigen, insbesondere gleichseitig sechseckigen Querschnitt aufweisen.According to a further embodiment, the exercise band can have a honeycomb surface structure. Such a surface gives the tape properties similar to that of a fabric, i.e. that it has a high tensile strength with high flexibility and low tendency to bulge and fold. This is achieved by the "bridges" of a gymnastic band designed in this way between the honeycombs. The webs advantageously extend at right angles to one another, so that the depressions in the surface plane have a rectangular, in particular square, cross section. This gives the band an essentially uniform stretching behavior. Alternatively, the depressions can each have a hexagonal, in particular equilateral, hexagonal cross section in the surface plane.
Die beiden Oberflächen bzw. die Oberflächenstrukturen des erfindungsgemäßen Gymnastikbandes können gleich oder verschieden sein.The two surfaces or the surface structures of the gymnastic band according to the invention can be the same or different.
Die Vertiefungen können z.B. durch. Prägen des gefertigten Gymnastikbands erzeugt werden. Alternativ ist es z.B. möglich,
die Vertiefungen bereits bei der Fertigung des Gymnastikbands etwa durch entsprechende Erhebungen beim Formgießen bzw. Extrudieren vorzusehen.The wells can, for example, by. Embossing of the gymnastics band produced. Alternatively, it is possible, for example, to provide the recesses already during the production of the gymnastic band, for example by means of corresponding elevations when molding or extruding.
Gemäß einer weiteren bevorzugten Ausführungsform umfasst das erfindungsgemäße Gymnastikband mindestens einen längslaufenden Verstärkungsstreifen aus einem vom Bandmaterial verschiedenen Material um die Gefahr des plötzlichen Durchreißens weiter zu verringern. Dieser bevorzugt reißfeste Verstärkungsstreifen kann z.B. eine Länge aufweisen, die der Länge des Bandes bei maximaler Dehnung entspricht; er kann z.B. zickzackförmig oder in Schlaufen in oder auf dem Band angeordnet sein.According to a further preferred embodiment, the gymnastic band according to the invention comprises at least one longitudinal reinforcement strip made of a material different from the band material in order to further reduce the risk of sudden tearing. This preferably tear-resistant reinforcement strip can e.g. have a length corresponding to the length of the tape at maximum stretch; e.g. be arranged in a zigzag shape or in loops in or on the belt.
Wiederum bevorzugt umfasst das Gymnastikband der vorliegenden Erfindung einen Indikator, der die Höhe der angewendeten Kraft anzeigt. Der Indikator kann z.B. ein Farbindikator oder ein Dehnungsmessstreifen, wie er bei Waagen verwendet wird, sein. Der Indikator kann aus einem piezoelektrischen Material bestehen. Die Verwendung dieses Indikators erlaubt es in vorteilhafter Weise, die angewendete Kraft zu kontrollieren und ermöglicht somit eine dosierte Therapie.Again, the exercise band of the present invention preferably includes an indicator that indicates the amount of force applied. The indicator can e.g. a color indicator or a strain gauge, as used in scales. The indicator can be made of a piezoelectric material. The use of this indicator advantageously allows the force applied to be controlled and thus enables dosed therapy.
Das erfindungsgemäße Gymnastikband kann, wie auch bei herkömmlichen Latex-Gymnastikbändern üblich, durch Aufschmelzen bzw. nachfolgendes Erstarren hergestellt werden. Erfindungsgemäß ist jedoch bevorzugt, das Gymnastikband durch das wesentlich preisgünstigere Extrudieren herzustellen. Zu diesem Zweck soll das Bandmaterial vorzugsweise ein extrudierbares Material sein.The gymnastic band according to the invention can, as is also usual with conventional latex gymnastic bands, be produced by melting or subsequent solidification. According to the invention, however, it is preferred to produce the gymnastic band by means of the much cheaper extrusion. For this purpose, the strip material should preferably be an extrudable material.
Bei einer bevorzugten Ausgestaltung- der Erfindung wird ein Bandmaterial verwendet, das bei einer Dehnung in Bandrichtung auch ohne den Einsatz von Zusatzstoffen eine im wesentlichen
lineare Kraft-Weg-Kennlinie aufweist. D.h., dass bei einer Dehnung des Gymnastikbands der Zugwiderstand im wesentlichen proportional mit der Dehnung des Gymnastikbands zunimmt; das Band erfüllt also bevorzugt im wesentlichen das Hooke'sche Gesetz . Ein Bandmatexial mit einem derartigen Verhalten kann in besonders vorteilhafter Weise zur Stärkung von Muskeln, Bändern und Sehnen des Bewegungsapparats angewendet werden: wie bereits vorstehend erwähnt ermöglicht es im Gegensatz zu herkömmlichen Gymnastikbändern, einen größeren Bewegungsumfang von Gelenkteilen, wodurch insbesondere die Beweglichkeit von Gelenken unter Belastung trainiert werden kann. Zudem wird durch den im Vergleich zu herkömmlichen Gymnastikbändern mit Dehnung des Gymnastikbands geringeren Anstieg des Zugwiderstands die Gefahr einer ungewollten Überlastung des Bewegungsapparats des Anwenders vermieden, beispielsweise bei vorgeschädigten bzw. schwachen Sehnen, wie etwa nach einem Sehnenriεs. Hierdurch kann nicht nur eine erneute Schädigung der Sehne, beispielsweise durch ansonsten auftretende mikroskopische Risse vermieden werden, sondern es kann auch der Verlauf einer Therapie günstig beeinflusst werden.In a preferred embodiment of the invention, a strip material is used which, when stretched in the strip direction, is essentially one without the use of additives has linear force-displacement characteristic. This means that when the gymnastic band is stretched, the tensile resistance increases substantially proportionally with the stretching of the gymnastic band; the tape therefore preferably essentially fulfills Hooke's law. A band material with such behavior can be used in a particularly advantageous manner to strengthen muscles, ligaments and tendons of the musculoskeletal system: as already mentioned above, in contrast to conventional gymnastics bands, it enables a greater range of motion of joint parts, which in particular increases the mobility of joints under load can be trained. In addition, the lower increase in tensile resistance compared to conventional gymnastic bands with stretching of the gymnastic band avoids the risk of undesired overloading of the user's musculoskeletal system, for example in the case of previously damaged or weak tendons, such as after a tendon tear. As a result, not only can renewed damage to the tendon, for example due to microscopic tears that otherwise occur, be avoided, but the course of therapy can also be favorably influenced.
Gemäß einer weiteren vorteilhaften Ausführungsform können die Enden des erfindungsgemäßen Gymnastikbandes als Schlaufen ausgebildet sein, die z.B. durch Verschmelzen hergestellt werden können. Alternativ können die Enden des Bandes aneinandergefügt sein (z.B. durch Verschmelzen der Enden), um eine endlose Schleife zu erhalten. Gegebenenfalls kann das Gymnastikband an den Enden mit Griffen versehen sein.According to a further advantageous embodiment, the ends of the gymnastic band according to the invention can be designed as loops which e.g. can be produced by fusing. Alternatively, the ends of the tape can be joined together (e.g. by fusing the ends) to create an endless loop. If necessary, the gymnastic band can be provided with handles at the ends.
Wie dargestellt wurde, weist das erfindungsgemäße Gymnastikband hinsichtlich Reißfestigkeit und Dehnverhalten hervorragende Eigenschaften auf. Zudem kann das Gymnastikband preisgünstig durch Extrudieren hergestellt werden.
Die Erfindung wird nun anhand von Ausführungsbeispielen dargestellt, wobei Bezug auf Fig. 1 genommen wird.As has been shown, the gymnastic band according to the invention has excellent properties with regard to tear strength and stretching behavior. In addition, the exercise band can be manufactured inexpensively by extrusion. The invention will now be illustrated using exemplary embodiments, reference being made to FIG. 1.
Fig. 1 zeigt eine schematische Darstellung im Querschnitt in Bandrichtung eines Ausführungsbeispiel des erfindungsgemäßen Gymnastikbands.Fig. 1 shows a schematic representation in cross section in the band direction of an embodiment of the exercise band according to the invention.
Fig. 1 zeigt einen Ausschnitt eines erfindungsgemäßen Gymnastikbands im Querschnitt in Bandrichtung, wobei der Schnitt senkrecht zur Bandebene geführt ist. Das Gymnastikband 1 ist aus dem thermoplastischen Elastomerem TPE-S gefertigt und durch Extrudieren hergestellt. Beide Oberflächen des Gymnastikbands sind mit einer Oberflächenstruktur versehen. Die Oberflächen weisen eine Vielzahl von Vertiefungen 4 auf, welche sich ausgehend von der Oberflächenebenen 2, 3 der beiden Seiten in Richtung der abgewandten Seite erstrecken. Die Vertiefungen 4 haben eine Rillenform, wobei sich die Rillen entlang der Bandrichtung des Gymnastikbands 1 erstrecken. Durch die Rillen 4 sind den Rillen 4 angrenzende Erhebungen 5 ausgebildet. Die Oberflächenstrukturen der beiden Seiten des Gymnastikbands wurde durch Prägen des durch Extrudieren hergestellten Gymnastikbands erzeugt. Durch die Oberflächenstruktur in Rillenform kann eine gezielte Schwächung des Zugwiderstands des Gymnastikbands 1 bei Dehnung erzielt werden.
Fig. 1 shows a section of a gymnastic band according to the invention in cross section in the direction of the band, the cut being made perpendicular to the band plane. The gymnastics band 1 is made of the thermoplastic elastomer TPE-S and manufactured by extrusion. Both surfaces of the exercise band are provided with a surface structure. The surfaces have a multiplicity of depressions 4 which, starting from the surface planes 2, 3 of the two sides, extend in the direction of the opposite side. The depressions 4 have a groove shape, the grooves extending along the band direction of the exercise band 1. The grooves 4 are formed by the grooves 4 adjacent elevations 5. The surface structures of the two sides of the exercise band were created by embossing the exercise band produced by extrusion. The surface structure in the form of grooves allows a targeted weakening of the tensile resistance of the gymnastic band 1 when stretched.
