Definitions
- the invention relates to a floorball stick with a blade, a substantially round shaft and a handle. Furthermore, the invention relates to a set of floorball sticks of different lengths. Furthermore, the invention relates to a floorball stick.
- Floorball English name "floorball”, is a team sport from the family of the stickball games, which include roller hockey and ice hockey. It is a game similar to ice hockey, where you can also play behind the goals.
- a conventional floorball stick is composed of a shank and a shovel.
- the upper end of the shaft hereafter referred to as the handle end of the shaft, is wrapped in a grip band, which ensures the necessary grip when playing.
- a cap is attached at the upper end of the shaft.
- the blade is connected to the shaft by means of one or more fastening screws, which run transversely to the longitudinal axis of the rod.
- the shaft may have a straight course or a sectionally curved course, as shown CH-A-695 480 known.
- the cross-sectional shape of the shaft may be different, the shapes having different play characteristics and handling. According to the regulations of the "International Floorball Federation", however, the stem must be at least in its lower half have a round cross-sectional shape with a radius of curvature of at least 9 mm.
- Shanks of circular or oval cross-section are known.
- a special form represents a shaft with a dual cross-sectional shape, which has an oval shape for the upper hand, and a round shape for the lower hand.
- shaft inserts also referred to as “stripes” or “oval kits”
- an originally round shaft shape in the grip area can be changed to an oval. The short or long shaft insert is attached to the shaft and then the grip band is wound over it.
- Grip tapes are usually self-adhesive, about 200 cm long and between 2.5 and 3 cm wide. They are wound spirally around the handle shell.
- Standard grips consist of a layer of foam which is sealed with a grippable and abrasion-resistant surface.
- Unihockey advocatesrs wear resulting in abrasion of the grip band or a displacement of the grip band and affect the secure grip. This results in the need to renew the grip at regular intervals, with an old grip strip and the underlying shaft must be cleaned to remove adhesive residue, which produce an irregular and bad beklebbare shaft surface, and then a new grip tape are glued to the shaft end got to. This change process is time consuming and costly.
- Another disadvantage is an inadequate ability to adjust the grip to a personal hand anatomy.
- the cross-sectional shape of the shaft is rectangular.
- CA-A-2 179 329 suggests it in a hockey stick before, a handle with rectangular cross-sectional shape in the hollow rectangular shaft form fit to insert and through Bonding to fix.
- U.S. Patent 5,816,961 also shows the positive insertion and sticking of a handle in a hockey stick.
- CA-A-2 270 681 shows an elastically expandable handle for a hockey stick, which is mounted with the help of compressed air over the stick.
- WO 2004/067100 refers to this as a disadvantage and proposes for hockey sticks with rectangular cross-sectional shape again before an insertable into the shaft handle. Mentioned in this document but also sticks with round cross-sectional shape.
- the attachment of the handle is made by a press fit of the handle in the shaft or by gluing and / or a screw. For the replacement of the handle, the release of the interference fit by pulling force or releasing the adhesive bond by heat is proposed.
- the fastener is at least partially relieved of the task of anti-rotation and a widening of the holes in the shaft for the fastener by a relative movement of the handle and shaft is avoided because it is collected by the separate rotation.
- the handle is configured as a handle that engages over the shaft and furthermore preferably has a multi-part construction with a rigid inner part and an elastic covering of the same.
- the shaft is designed in several parts and in particular has a separate shaft grip part. The adaptation of the pole length can then be done with otherwise unchanged shaft by replacing a shaft portion against a shaft portion of another length, in particular by the replacement of the shaft grip part against a shaft grip part of a different length.
- Another object is to provide a set of floorball sticks of different lengths, which is easy to manufacture.
- the fastening with a fastening means extending in the longitudinal direction of the shaft avoids the previously used screw extending transversely through the shaft and the blade. As a result, the shaft is not weakened at this point. This allows a longer life of the shaft. Further deleted a possible risk of injury to the players.
- the shaft is held in the receiving part of the blade by clamping and it is provided a rotation.
- FIG. 1 shows a floorball stick 1 without the blade (which is also referred to as a blade).
- This racket has a shaft 4 and a handle 2 releasably secured thereto.
- the blade-side end 9 of the shaft 4 of the racket is inserted in the full racket in the receiving area 13 of the blade 3.
- the blade 3 is in FIG. 2 shown separately.
- a complete racket thus results in mounted blade 3 or in conjunction with the FIGS. 1 and 2 ,
- FIG. 8 shows an exploded view of the handle portion of the floorball stick.
- the shaft 4 is shown with only a part of its upper portion 5.
- the handle 2 has a rigid inner part 10 and a comparison in the elastic outer part 11. Both parts are preferably made of plastic and in the preferred embodiment, the outer part 11 is formed in the manufacture directly around the inner part 10 around, for example by introducing the plastic material for the outer part in a form in which the inner part is arranged. A coating of the inner part with an elastic outer skin, which forms the outer part 11, is possible.
- the inner part 10 may be closed by a separate cover 10a.
- the handle 2 could also be a one-piece handle without the separation in the inner part and the outer part.
- the handle 2 is pushed for attachment to the shaft 4 in the shaft longitudinal direction over the shaft, so that the shaft is received in the handle.
- the attachment against the pulling of the handle in Shaft longitudinal direction is effected with a fastening means 19 which passes through the shaft.
- this fastener is shown as a screw 19. This is introduced on one side into a recess of the handle, which is aligned with correspondingly recesses in the shaft when fully inserted into the handle shaft.
- a thread is provided in this, in which the screw 19 can be screwed.
- the thread is provided in a plate 12, which is secured in the handle.
- the screw head of the screw 19 is covered with a cover plate 19a.
- the rotation is provided with cooperating positive surfaces on the handle and shaft in the region of the fastener, which is preferred.
- the fastening means can then during fastening, or when tightening the screw, cause the surfaces are pressed together in the direction of action of the fastener, which causes the play-free rotation by means of the surfaces.
- the rotation can also be designed so that the surfaces act on each other under the effect of the fastener without bias by at least one surface is elastically deformed by the other when pushing the handle on the shaft.
- diametrically opposed surfaces are provided on the handle for forming the cooperating surfaces.
- FIG. 10 has a cross section along the section line AA of FIG. 9 shows.
- the surfaces are in this example on the one hand on the handle or on the inner part 10 of the handle in Shape of a web 20 provided and opposite as a flat surface 21.
- the cooperating surfaces of the rotation on the shaft are shaped accordingly.
- the web 20 engages in a groove 22 of the shaft 4 and the portion 5 of the shaft, which is particularly in FIG. 8 is clearly visible.
- the flat surface 21 bears against a flat surface 23 of the shaft 4 or section 5.
- the web 20 may be rectangular in cross-section, but is trapezoidal in the example shown, which is preferred.
- the fastener or the screw 19 extends through the web 20, it can press it into the groove.
- the fastening means presses the surfaces 21 and 23 against each other.
- the anti-twist device extends in the longitudinal direction beyond the direct area of the fastening means, so that a sufficiently large total area is available for securing against rotation.
- the "full-surface" anti-rotation in which the respective surfaces of the handle and shaft essentially abut each other with their entire surface
- guides which provides greater flexibility allow the shaft in the grip, as in FIG. 11 shown a section along the section line BB of FIG. 8 shows.
- the shank side, the groove 22 and the surface 23 serve as guide surfaces and the handle side webs 24 and 25 are provided.
- the webs 24 and 25 are preferably different in height ( FIG. 11 ) and also extend differently far towards the blade ( FIG. 9 ) Which as a further function, a single defined possibility for pushing the handle on the shaft results.
- the attachment means ends the area in which the handle and shaft are connected to each other, which in FIG. 9 it can be seen, wherein the upper end of the shaft portion 5 can be seen.
- the shaft 4 or 5 is also acted upon on the inside by the handle, in particular in the fastening region of the fastening means.
- the handle thus forms an inner support for the shaft, so that it does not deform even at low wall thickness under the influence of the fastener.
- FIG. 10 is the corresponding support as a round sleeve 30 with a plurality of webs 31 visible. This sleeve 30 extends downwardly as a part of the rigid inner part from above in the handle and forms in the inner part of an annular space, in which the end of the shaft enters, when the handle is pushed over the shaft.
- the shaft itself is formed in the longitudinal direction of several sections. This can produce manufacturing advantages, but gives the possibility in particular to influence the diameter and the properties of the shaft along its length in a simple manner.
- FIGS. 1 to 6 show an embodiment.
- the shaft is in FIG. 1 shown as a four-part shaft.
- the handle 2 is shown.
- the shaft 4 has on the handle side, the already mentioned section 5, which is circular below the handle, but within the handle, but preferably the above-explained and eg in FIG. 8 has apparent form.
- the section 5 can itself consist eg of two nested parts, which is not shown here. In the direction of the blade then follows the section 6, which in FIG. 3 is shown in cross-section along the section line VV.
- the section 6 is preferably conical in order to adapt the section 5 of smaller diameter to the section 7, which adjoins the section 6 on the blade side.
- Section 7 of the shaft is in FIG. 4 in cross section shown. It is made up of two concentrically arranged parts. Section 7 is followed by section 8, which initially has an oval cross-sectional shape (section along the line SS in FIG. 5 ) and subsequently in the area 8 'has a special shape for the rotationally secure attachment of the blade (section along the line RR in FIG. 6 ).
- the individual sections of the shaft 4 can be inserted into one another and attached to one another by gluing.
- the material of the sections is for example a conventional plastic, as it is known for the production of floorball sticks or a conventional composite material or a carbon fiber composite.
- the different sections may consist of different materials, depending on their function and load. The choice of the known materials, the expert can readily meet with his expertise.
- FIG. 7 shows three Unihockeyeaur 1, which are composed of different sections.
- the previously explained sections 5, 6, 7 and 8 are provided, but of course, a different number and distribution can be provided.
- the length of the clubs of a set of clubs of different lengths is now determined by the fact that the different length is achieved by only one section, preferably the grip-side section of the shaft, which is used in different lengths for the clubs of different length , In the example shown, this is the section designated by the various beaters with 5 or 5 'or 5 ", which is provided in different lengths All other sections 6, 7 and 8 and also the handle 2 each have the same length for all bats In this way, rackets of different lengths can be manufactured in a cost effective manner, in which also the club characteristics vary only slightly with length.
- the explained aspect of the length selection by the choice of different lengths sections in the rackets of a racket set may be combined with the previously discussed aspect of the interchangeable
- Another aspect of the invention relates to the attachment of the blade 3 on the shaft 4 of a floorball stick. This may or may not be combined with the aforementioned aspects of the interchangeable handle and / or the racket set with bats of different lengths.
- FIG. 12 a longitudinal section at the point of attachment of the blade 3 on the shaft 4 and the lowest portion 8 'of the shaft 4 in a shaft formed of a plurality of sections.
- FIG. 12 shows only the shaft-side receiving part 13 of the blade or trowel. 3
- the shaft is preferably formed at its lower end deviating from a circular cross-sectional shape in order to form a rotation with respect to the blade 3 with appropriate shaping of the receiving part of the blade 3.
- the fastener can thus be relieved of the task to ensure the rotation of the attachment blade-shaft.
- Two round sections 40 and 41 of the cross-sectional shape are interconnected by two groove-shaped sections 43.
- two inserts or possibly only one insert 55 can be inserted in a form-fitting manner in sections 43.
- the shape of the inserts follows, as shown by the dashed curves, the radius of curvature of the round sections 40 and 41 FIG.
- connection between the shaft and blade can be provided such a shape of the shaft and the corresponding, On the shaft abutting surfaces of the receptacle 13 are formed substantially opposite, so that the blade is thereby secured against rotation about the shaft longitudinal axis and secured against rotation.
- attachment of blade and shank can indeed be carried out without such or other shaped anti-rotation, but this is not preferred.
- the fastening means which comprises in particular a screw 15 and a nut 17, extends substantially in the longitudinal direction of the shaft.
- the screw could be screwed into a tightly arranged in the stem stopper (for example, carries a nut or itself has an internal thread), so that the blade is fixed directly by the screw on the shaft in the shaft longitudinal direction when the screw, as shown, with their head on the blade supported (with the interposition of a washer 50).
- the attachment of the blade to the shaft takes place in that the shaft is clamped to the blade.

Abstract
Description
Die Erfindung betrifft einen Unihockeyschläger mit einer Schaufel, einem im Wesentlichen runden Schaft und einem Griff. Ferner betrifft die Erfindung einen Satz von Unihockeyschlägern unterschiedlicher Länge. Weiter betrifft die Erfindung einen Unihockeyschläger.The invention relates to a floorball stick with a blade, a substantially round shaft and a handle. Furthermore, the invention relates to a set of floorball sticks of different lengths. Furthermore, the invention relates to a floorball stick.
Unihockey, englische Bezeichnung "floorball", ist eine Mannschaftssportart aus der Familie der Stockballspiele, zu denen auch Rollhockey und Eishockey gehören. Es handelt sich dabei um ein dem Eishockey ähnliches Spiel, bei dem auch hinter den Toren gespielt werden kann.Floorball, English name "floorball", is a team sport from the family of the stickball games, which include roller hockey and ice hockey. It is a game similar to ice hockey, where you can also play behind the goals.
Ein herkömmlicher Unihockeyschläger ist aus einem Schaft und einer Schaufel zusammengesetzt. Das obere Ende des Schafts, im Folgenden griffseitiges Ende des Schafts genannt, ist mit einem Griffband umwickelt, welches beim Spielen die nötige Griffigkeit sicherstellt. Am oberen Ende des Schafts ist eine Verschlusskappe angebracht. Am unteren Ende des Schafts, im Folgenden schaufelseitiges Ende des Schafts genannt, ist die Schaufel mit dem Schaft mittels einer oder mehrerer Befestigungsschrauben verbunden, welche quer zur Längsachse des Stocks verlaufen. Der Schaft kann einen geraden Verlauf oder auch einen abschnittsweise gekrümmten Verlauf haben, wie aus
Die Querschnittsform des Schafts kann unterschiedlich sein, wobei die Formen verschiedene Spieleigenschaften und Handling aufweisen. Gemäss den Bestimmungen der "International Floorball Federation" muss der Schaft aber mindestens in seiner unteren Hälfte eine runde Querschnittsform mit einem Rundungsradius von mindestens 9 mm aufweisen. Es sind Schäfte mit kreisrundem oder ovalem Querschnitt bekannt. Eine Spezialform stellt ein Schaft mit einer dualen Querschnittsform dar, welcher eine ovale Form für die obere Hand, und eine runde Form für die untere Hand hat. Mit sogenannten Schafteinlagen, auch als "stripes" oder "oval kits" bezeichnet, kann dabei eine ursprünglich runde Schaftform im Griffbereich zu einer ovalen verändert werden. Die kurze oder lange Schafteinlage wird dazu an den Schaft befestigt und anschließend wird das Griffband darüber gewickelt.The cross-sectional shape of the shaft may be different, the shapes having different play characteristics and handling. According to the regulations of the "International Floorball Federation", however, the stem must be at least in its lower half have a round cross-sectional shape with a radius of curvature of at least 9 mm. Shanks of circular or oval cross-section are known. A special form represents a shaft with a dual cross-sectional shape, which has an oval shape for the upper hand, and a round shape for the lower hand. With so-called shaft inserts, also referred to as "stripes" or "oval kits", an originally round shaft shape in the grip area can be changed to an oval. The short or long shaft insert is attached to the shaft and then the grip band is wound over it.
Griffbänder sind meistens selbstklebend, etwa 200 cm lang und zwischen 2,5 und 3 cm breit. Sie werden spiralförmig um die Griffschale gewickelt. Standard-Griffbänder bestehen aus einer Lage Schaumstoff, die mit einer griffsicheren und abriebfesten Oberfläche versiegelt wird. Im Gebrauch des Unihockeyschlägers ergeben sich Abnutzungserscheinungen, die einen Abrieb des Griffbandes oder ein Verschieben des Griffbandes bewirken und den sicheren Griff beeinträchtigen. Daraus entsteht die Notwendigkeit, das Griffband in regelmässigen Zeitabständen zu erneuern, wobei ein altes Griffband abgezogen und der darunterliegende Schaft gereinigt werden muss, um Kleberückstände zu entfernen, welche eine unregelmässige und schlecht beklebbare Schaftoberfläche erzeugen, und anschliessend ein neues Griffband an das Schaftende geklebt werden muss. Dieser Wechselprozess ist zeitraubend und kostspielig. Ein weiterer Nachteil ist eine unzureichende Möglichkeit, den Griff auf eine persönliche Handanatomie anzupassen.Grip tapes are usually self-adhesive, about 200 cm long and between 2.5 and 3 cm wide. They are wound spirally around the handle shell. Standard grips consist of a layer of foam which is sealed with a grippable and abrasion-resistant surface. In the use of Unihockeyschlägers wear resulting in abrasion of the grip band or a displacement of the grip band and affect the secure grip. This results in the need to renew the grip at regular intervals, with an old grip strip and the underlying shaft must be cleaned to remove adhesive residue, which produce an irregular and bad beklebbare shaft surface, and then a new grip tape are glued to the shaft end got to. This change process is time consuming and costly. Another disadvantage is an inadequate ability to adjust the grip to a personal hand anatomy.
Bei Eishockeyschlägern ist die Querschnittform des Schafts rechteckig.
Es ist Aufgabe der Erfindung, einen verbesserten Unihockeyschläger mit einem auswechselbaren Griff zu schaffen.It is an object of the invention to provide an improved floorball stick with a replaceable handle.
Diese Aufgabe wird bei dem eingangs genannten Unihockeyschläger dadurch gelöst, dass der Schaft und der Griff mit als Verdrehsicherung formschlüssig zusammenwirkenden Flächen versehen sind, und dass mindestens ein lösbares, den Schaft durchsetzendes Befestigungsmittel für den Griff vorgesehen ist.This object is achieved in the above-mentioned floorball club in that the shaft and the handle are provided with positively locking cooperating surfaces as anti-rotation, and that at least one releasable, the shaft passing through fastener is provided for the handle.
Durch die mechanische Verdrehsicherung mit formschlüssig zusammenwirkenden Flächen am an sich runden Schaft bzw. am Griff, ergibt sich eine sehr gute Sicherung gegen ein Drehen des Griffs am Schaft. Damit kann auf eine Klebung in der Regel verzichtet werden und es genügt ein lösbares Befestigungsmittel, welches insbesondere den Schaft durchsetzt, um den Griff in Schaftlängsrichtung zu fixieren. Eine lösbare, z.B. durch Wärme lösbare, Klebung als Befestigungsmittel kann aber zusätzlich oder anstelle des durchsetzenden Befestigungsmittels eingesetzt werden. Dabei ist das Befestigungsmittel von der Aufgabe der Verdrehsicherung mindestens teilweise entlastet und ein Aufweiten der Bohrungen im Schaft für das Befestigungsmittel durch eine Relativbewegung von Griff und Schaft wird vermieden, da diese von der separaten Verdrehsicherung aufgefangen wird. Durch das lösbare Befestigungsmittel, welches z.B. ein Gewindebolzen ist, ergibt sich eine sehr einfache Auswechselbarkeit des Griffes.Due to the mechanical anti-rotation with positively cooperating surfaces on the per se round shaft or on the handle, there is a very good security against rotation of the handle on the shaft. This can be dispensed with gluing in the rule and it is sufficient a releasable fastening means, which in particular passes through the shaft to fix the handle in the longitudinal direction of the shaft. A detachable, eg heat-releasable, gluing as a fastening means but in addition to or instead of the enforcing Fastener can be used. In this case, the fastener is at least partially relieved of the task of anti-rotation and a widening of the holes in the shaft for the fastener by a relative movement of the handle and shaft is avoided because it is collected by the separate rotation. Due to the releasable fastening means, which is for example a threaded bolt, results in a very simple interchangeability of the handle.
Bevorzugt ist der Griff als ein den Schaft übergreifender Griff ausgestaltet und er weist ferner bevorzugt eine mehrteilige Konstruktion mit einem starren Innenteil und einer elastischen Umhüllung desselben auf. Ferner ist es bevorzugt, dass der Schaft mehrteilig ausgeführt ist und insbesondere einen separaten Schaftgriffteil aufweist. Die Anpassung der Stocklänge kann dann bei ansonsten unverändertem Schaft durch Auswechslung eines Schaftteils gegen ein Schaftteil anderer Länge erfolgen, insbesondere durch die Auswechslung des Schaftgriffteils gegen ein Schaftgriffteil anderer Länge.Preferably, the handle is configured as a handle that engages over the shaft and furthermore preferably has a multi-part construction with a rigid inner part and an elastic covering of the same. Furthermore, it is preferred that the shaft is designed in several parts and in particular has a separate shaft grip part. The adaptation of the pole length can then be done with otherwise unchanged shaft by replacing a shaft portion against a shaft portion of another length, in particular by the replacement of the shaft grip part against a shaft grip part of a different length.
Eine weitere Aufgabe ist es, einen Satz von Unihockeyschlägern unterschiedlicher Länge zu schaffen, welcher einfach herstellbar ist.Another object is to provide a set of floorball sticks of different lengths, which is easy to manufacture.
Diese Aufgabe wird mit einem Satz von Unihockeyschlägern nach Anspruch 11 gelöst.This object is achieved with a set of floorball sticks according to
Es ist ferner Aufgabe der Erfindung bei einem Unihockeyschläger eine verbesserte Befestigung der Schaufel am Schaft zu schaffen.It is also an object of the invention to provide a Unihockeyschläger improved attachment of the blade on the shaft.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 13 gelöst.This object is achieved with the features of
Die Befestigung mit einem sich in Schaftlängsrichtung erstreckenden Befestigungsmittel vermeidet die bisher verwendete, quer durch den Schaft und die Schaufel verlaufende Schraube. Dadurch wird der Schaft an dieser Stelle nicht geschwächt. Dies erlaubt eine längere Lebensdauer des Schafts. Ferner entfällt eine mögliche Verletzungsgefahr für die Spieler. Bevorzugt wird der Schaft im Aufnahmeteil der Schaufel durch Klemmung gehalten und es ist eine Verdrehsicherung vorgesehen.The fastening with a fastening means extending in the longitudinal direction of the shaft avoids the previously used screw extending transversely through the shaft and the blade. As a result, the shaft is not weakened at this point. This allows a longer life of the shaft. Further deleted a possible risk of injury to the players. Preferably, the shaft is held in the receiving part of the blade by clamping and it is provided a rotation.
Weitere bevorzugte Ausgestaltungen ergeben sich aus den weiteren abhängigen Ansprüchen.Further preferred embodiments will become apparent from the other dependent claims.

Zunächst wird ein erster Aspekt der Erfindung, der die lösbare Befestigung des Griffs 2 am Schaft 4 betrifft, an Hand der
Im gezeigten Beispiel ist die Verdrehsicherung mit zusammenwirkenden formschlüssigen Flächen an Griff und Schaft im Bereich des Befestigungsmittels vorgesehen, was bevorzugt ist. Das Befestigungsmittel kann dann beim Befestigen, bzw. beim Anziehen der Schraube, bewirken, dass die Flächen in Wirkungsrichtung des Befestigungsmittels aneinander gepresst werden, was die spielfreie Verdrehsicherung mittels der Flächen bewirkt. Vorzugsweise sind ebene Flächen vorgesehen, gekrümmte Flächen können aber auch vorgesehen sein. Die Verdrehsicherung kann aber auch so ausgestaltet sein, dass die Flächen auch ohne Wirkung des Befestigungsmittels einander unter Vorspannung beaufschlagen, indem mindestens die eine Fläche durch die andere beim Aufschieben des Griffes auf den Schaft elastisch verformt wird.In the example shown, the rotation is provided with cooperating positive surfaces on the handle and shaft in the region of the fastener, which is preferred. The fastening means can then during fastening, or when tightening the screw, cause the surfaces are pressed together in the direction of action of the fastener, which causes the play-free rotation by means of the surfaces. Preferably flat surfaces are provided, but curved surfaces can also be provided. However, the rotation can also be designed so that the surfaces act on each other under the effect of the fastener without bias by at least one surface is elastically deformed by the other when pushing the handle on the shaft.
In dem gezeigten Beispiel sind am Griff zur Ausbildung der zusammenwirkenden Flächen einander diametral gegenüberliegende Flächen vorgesehen. Dies ist bevorzugt und besonders in
In Richtung zur Schaufel hin, bzw. nach unten, wird die "vollflächige" Verdrehsicherung (bei der also die entsprechenden Flächen von Griff und Schaft im Wesentlichen jeweils mit ihrer ganzen Oberfläche aneinander anliegen) in dem bevorzugten Beispiel durch Führungen abgelöst, welche eine grössere Flexibilität des Schafts im Griff erlauben, wie in
Oberhalb des Befestigungsmittels endet der Bereich, in dem Griff und Schaft miteinander verbunden sind, was in
Vorzugsweise ist der Schaft selber in Längsrichtung aus mehreren Abschnitten gebildet. Dies kann herstellungstechnische Vorteile bilden, gibt aber besonders die Möglichkeit, den Durchmesser und die Eigenschaften des Schaftes entlang seiner Länge auf einfache Weise zu beeinflussen. Die

Ein weiterer Aspekt der Erfindung betrifft die Befestigung der Schaufel 3 am Schaft 4 eines Unihockeyschlägers. Dieser kann mit den vorgenannten Aspekten des auswechselbaren Griffs und/oder des Schlägersatzes mit unterschiedlich langen Schlägern kombiniert sein oder nicht.Another aspect of the invention relates to the attachment of the
Zur Erläuterung dieses Aspekts zeigt
Der Schaft ist an seinem unteren Ende vorzugsweise abweichend von einer kreisrunden Querschnittsform geformt, um mit entsprechender Formgebung des Aufnahmeteils der Schaufel 3 eine Verdrehsicherung für die Schaufel 3 zu bilden. Das Befestigungsmittel kann damit von der Aufgabe entlastet werden für die Verdrehsicherung der Befestigung Schaufel-Schaft zu sorgen. Bevorzugt ist dabei eine Form des Endes des Schaftes, wie sie in
Wie in
In dem gezeigten Beispiel weist der Schaft 4 an seinem schaufelseitigen Ende den verjüngten Teil 9 auf, welcher in den schaftseitigen Teil bzw. die Aufnahme 13 der Schaufel bzw. Schaufel eingesteckt wird. Die Dimensionierung von Schaft und Aufnahme sind dabei vorzugsweise so gewählt, dass sich die dargestellte fluchtende Aufnahme des Schafts in der Aufnahme ergibt, so dass kein äusserer Absatz zwischen Schaufel und Schaft vorhanden ist. Der verjüngte Teil 9 des Schafts 4 bzw. der Abschnitts 8 des Schafts, hat eine so dimensionierte Dicke, dass er zwischen der Wand 18 und einer Innenwand 19 in der Aufnahme 13 zu liegen kommt, welche sich konzentrisch zur Aussenwand 18 im Inneren der Aufnahme befindet. Es ergibt sich somit ein Formschluss für die erwähnte Verdrehsicherung. Ein hohlzylindrischer Innenteil 19a bildet eine schräge Auflagefläche für einen Zylinderkörper 16, der mit einer Gegenschräge versehen ist. Die Innenwand 19 ist in ihrer Höhe ebenfalls an die schräge Fläche des Innenteils 19a angepasst. Die Innenwand 19 und der Innenteil 19a können einstückig mit einem Zwischenboden 20 der Schaufel 3 ausgebildet sein. Die in Richtung der Längsachse der Schafts 4 angeordnete Schraube 15 wird von einer der Schaufel zugewandten Seite der Zwischenwand 20 durch diese eingeführt und durch ein Loch in dem Zylinderkörper 16 geschoben. Schaftseitig ist der Zylinderkörper mit einem Gewinde versehen, z.B. derart, dass die Mutter 17 unbeweglich und konzentrisch zur Aussenwand des Schafts 4 eingesenkt ist. Die Mutter 17 nimmt das Ende der Schraube 15 auf.In the example shown, the
Beim Anziehen der Schraube 15 wird der Zylinderkörper durch die Schraube in der Figur nach unten gezogen und dabei in Folge der schiefen Ebene zunehmend in der Figur nach links gedrückt. Der Schaft wird dadurch zwischen der Wand 18 und dem Zylinder 16 eingeklemmt und damit reibschlüssig festgehalten. Der vorgängig erläuterte Formschluss zwischen Schaft und Aufnahme des Schafts in der Schaufel ergibt die Sicherung gegen eine Rotation der Schaufel um die Schaftlängsachse.When tightening the
Die beschriebene Ausführungsform der Befestigung des Schafts an die Schaufel stellt ein Beispiel dar. Andere Ausführungsformen für die Befestigung mit einer in Richtung der Längsachse des Schafts angeordneten Schraube können gleichermassen eingesetzt werden. Der Körper für die Befestigung kann z.B. ein Kegelstumpf mit einer in Richtung der Schaufel zeigenden Deckfläche sein, dessen Mantelfläche beim Anziehen der Schraube gegen innenwandig am Schaft angeordnete Vorsprünge oder Schaftflächen drückt und dadurch eine nach aussen gerichtete Spreizbewegung der Schaftwand bewirkt.The described embodiment of the attachment of the shank to the blade is an example. Other embodiments for attachment to a screw arranged in the direction of the longitudinal axis of the shank can equally be used. The body for attachment may e.g. a truncated cone with a pointing in the direction of the blade top surface, the lateral surface presses when tightening the screw against the inside of the shaft arranged projections or shaft surfaces and thereby causes an outward spreading movement of the shaft wall.
Der Vorteil dieser Anordnung ist die Möglichkeit einer sicheren Befestigung der Schaufel an den Schaft 4, ohne dass die dafür notwendigen Befestigungsmittel sichtbar sind bzw. hervorstehen oder dass ein gestufter Übergang zwischen Schaufel und Schaft entsteht, wodurch, wegen der Präsenz scharfer Kanten Verletzungsgefahr bestünde.The advantage of this arrangement is the possibility of secure attachment of the blade the
