Description

Shuttlecock

The invention relates to a shuttlecock comprising a core impact cap and a shuttlecart, which in turn comprises a fixing part and a jacket and the fixing part is inserted into the core impact cap.

Technological background

The geometry of the known from the prior art shuttlecock balls, the weight of the same and the attachment between the impact cap and the basket and special accessories, such as an outward (forward) usable lighting on the cap of the striking cap, according to the priority needs of users in different Way more or less have been put in the foreground. It must therefore always compromises are found, which must decide to have a shuttlecock fluidly and provided with defined weight for competitive sports have optimal flight characteristics or should the sports equipment for grassroots use relatively universal and simply have good performance properties, including last but not least the shelf life of the product itself counts.

It will be explained below with reference to selected examples of the prior art, with which solutions has been tried so far to design high quality shuttlecocks.

According to DE 199 41 916 A1 a shuttlecock ball is proposed, which consists essentially of a conically shaped basket with molded fixing pin and a slidable over the latter impact cap. An improved positive fixation between the two is made by the fixing pin engages with a mounted at its outwardly facing end radially projecting edge in an adequate groove on the bottom of the striking cap, the securing of this layer by one or more pressing rings, which over the cylindrical Outside perimeter of the impact cap are pulled, is made. By pressing these rings in the elastic material of the impact cap a non-destructive separation between the basket and impact cap is no longer possible. In EP 1 635 971 B1 a shuttlecock ball is mentioned. This is analogous to the aforementioned solution equipped with a basket and percussion cap, which are toroidal rings in an annular groove between the basket and percussion cap or in the percussion cap itself to improve the flight behavior, a desired noise generation or better visual recognition - during flight - are. For these rings while different materials of geometric dimensions are provided, and they also for generating an acoustic perception, during the flight of the Flugkorbballs, z. B. are provided with holes. Furthermore, the outer surface of the impact cap, in the region of the dome, characterized by trough-like recesses. Ring groove-like depressions for receiving the toroidal rings are according to a variant of this solution in the cylindrical portion on the outer surface of the striking cap.

With DE 10 2005 039 121 A1, a shuttlecock is presented as a kit for individual production (of the same). It consists essentially of individual connectable with the impact cap segments of a basket, wherein the segments can be fixed in pairs by an inner clamping ring in the lower basket area together and then the segments are connected to the striking cap, wherein one or more cap rings, formed as press rings, the Secure the position of the basket segments inside the striking cap. Above the edge of the striking cap and at the beginning of the basket insert, an additional stabilizing for the durability of the construction and to improve the flight characteristics attached outer clamping ring can be provided.

According to DE 10 2007 041 169 A1, a shuttlecock has become known in which in addition to the usually required strength between the basket and the striking cap, by means of the known elements pressing rings, the formation of the basket for improving the flight characteristics is in the foreground. Thus, the basket is provided on its outer edge terminating outward therefrom with inwardly inclined edges, which are also wavy cut. In the individual separated by transverse webs segments of the basket, axially extending, segment webs are present, which are spaced differently in groups, in particular in the outwardly limiting the basket end segment. In a variant of this solution, the pressing rings, flush with the outer surface of the cylindrical portion of the striking cap, are sunk into the striking cap. From the illustrated prior art, it can be seen that the attachment between the basket and striking cap still receives full attention and it has not been possible to dispense with the usually used and at least manually poorly negotiable pressing rings.

It is therefore necessary to look for a solution that makes it easier to fix the connection between the basket and the impact cap of a shuttlecock ball.

Thus, it is an object of the invention to provide a shuttlecock having a particularly strong connection between the basket and impact cap.

Summary of the invention

This object is achieved by a shuttlecock with the features of the first claim.

Thus, the invention relates to a shuttlecock comprising a core impact cap and a shuttlecart, which in turn comprises a fixing part and a jacket. In this case, the fixing part is inserted into the core impact cap, wherein the assembled component of fixing part and core impact cap has a cohesive encapsulation. The advantage of the invention lies in a particularly strong and non-destructive detachable connection between the core impact cap with fixing part and the encapsulation. The encapsulation forms at least part of the impact cap. Thus, a particularly strong and non-destructive detachable connection between the impact cap and the flight cage is made. It is also advantageous that no anchoring on the jacket or on the fixing part of the flying basket is necessary for this connection. In the present invention, fixing part is also to be understood as a fixing pin, which is arranged on the tapering end of a substantially conically shaped jacket of the flying basket. The fixing pin or the fixing part is arranged within the striking cap. In the present invention, the impact cap is composed of a core impact cap and the encapsulation.

The shuttlecock has a striking cap which includes the core impact cap. The outer shape of the striking cap is composed of two parts. A substantially cylindrical part, with two round base surfaces and a curved circumferential side surface, wherein the circumferential side surface is arranged parallel to a longitudinal axis of the fixing pin and has one of the base surfaces to the shell of the shuttlecock. The second part of the outer shape is formed by a dome-shaped or hemispherical part arranged on the base surface facing away from the jacket. It should be noted that the description of the two parts of the striking cap only serve to explain the outer shape and give no conclusions about the manufacture and composition of the striking cap. In a preferred embodiment, the base surface facing away from the casing has a larger radius than the base surface facing the casing. This creates a conical or teardrop-shaped outer shape of the impact cap, which positively influences the flight characteristics of the shuttlecock ball.

According to the invention, the connection between the shuttlecock, that is to say the jacket with the arranged fixing part, and the impact cap are designed as a material fit. Cohesive compounds in the context of the invention are those in which the connection partners are held together by atomic or molecular forces. They are at the same time non-releasable compounds which can only be separated by decomposing the connecting means. The cohesive connection according to the invention can be a monolithic compound, encapsulation and core impact cap being made in one piece, or being produced by means of soldering, welding, gluing, vulcanizing or dipping, spraying or by injection molding.

In a preferred embodiment of the invention, the cohesive connection is made by means of dipping. For this purpose, the fixing part is first introduced into a preformed core impact cap. The resulting component of jacket and fixing part, and this surrounding core impact cap is then dipped with the core impact cap first in a suitable liquid material, so that the core impact cap and the fixing part are completely enclosed or encapsulated by the liquid material. The jacket includes construction conditionally directly on the fixing part. Thus, parts of the shell in the region of the fixing part are at least wetted by the liquid material. This has the advantage that forms a stepless transition between the impact cap and the coat of the Flugkorbballs, which in turn positively influences the flight characteristics of the Flugkorbballs and prevents breakage of the webs. Furthermore, it is preferred that the cohesive connection is produced by means of an injection molding process.

It is therefore preferred a shuttlecock, wherein the realized by means of dipping and / or injection molding of the core impact cap cohesive encapsulation comprises parts of the shell. The liquid is preferably a material which changes to the solid state at room temperature and which also belongs to the group of elastomers. Both natural materials such as rubber but also thermoplastics, rubber, latex, silicone and miravites are preferred. In order to influence in particular the rebound resilience, these materials can be processed in different designs, in particular with regard to their properties such as density and elasticity.

In a particularly preferred embodiment of the invention, the encapsulation comprises one or more encapsulation layers, which adjoin the outer surface of the core impact cap or an inner encapsulation layer over part or all of its surface. Here, starting from the core impact cap, a first encapsulation layer is integrally bonded to the core impact cap and to parts of the shell. Preference is given to one to five encapsulation layers, particularly preferably one to four encapsulation layers, more preferably one to three encapsulation layers. The individual encapsulation layers are advantageously designed either from the same material or from different materials. In particular, in the combination of different materials within the individual encapsulation layers, the physical properties of the materials, in particular the density, which directly affects the weight of the shuttlecock ball, as well as the elasticity, which in turn affects the rebound resilience vary. At least one, in particular the first, encapsulation layer is preferably produced by means of dipping, potting and / or injection molding.

In a further preferred embodiment of the invention, at least one outer encapsulation layer has a recess. This serves in particular for receiving an application. In this case, the shape and size of the recess correspond to a negative image of a region of the application intended for attachment to the impact cap. The application is preferably arranged in a material and / or form-fitting manner in the receptacle. The fixation of the application is preferably carried out by gluing and / or by locking. The application is preferably arranged in an area of the impact cap on which, with great probability or with optimal play behavior during the use of the shuttlecock ball, a contact between the racquet and the shuttlecock takes place. Thus, the rebound resilience is specifically optimized.

The application shows in comparison to other components of the striking cap another, in particular higher, elasticity, another, in particular brighter color and / or a reflection behavior. The advantage of a higher elasticity lies in an optimized power transmission from the racket to the ball when hitting the ball. A color-projecting and / or reflective embodiment of the application advantageously leads to a player being able to better recognize the optimum position when the ball bounces or falls, thus improving its play.

In a further preferred embodiment of the invention, it is provided that elastic moduli are arranged within the impact cap, in particular in a boundary region between the application and the core impact cap and / or encapsulation layer. Advantageously, these elastic moduli, in particular in the impact region of the impact cap, have a positive influence on the rebound resilience of the shuttlecock ball. The elastic moduli comprise a material which has a higher elasticity than the core impact cap or one of the encapsulation layers. Advantageously, they are arranged symmetrically in the impact cap with respect to an axis of rotation of the flight cage.

The last encapsulation layer and / or the outer surface of the application, that is the region of the impact cap which defines the outer shape of the impact cap, advantageously has contours, in particular circular and / or honeycomb-shaped depressions, which increase the aerodynamic character of the shuttlecock ball. In addition, their edges are preferably designed such that they increase a grip on the racket clothing and thus provide more accuracy.

In addition, colored, in particular luminous, preferably fluorescent materials can be applied to the last encapsulation layer. These can also be applied in layers by means of potting. They make it possible to increase the visibility of the shuttlecock ball, especially in restricted light and visibility conditions. It is also advantageous if the impact cap has one or more channels which are arranged parallel to the extension direction of the shuttlecock ball. The channels are preferably penetrating openings which generate noises, in particular a whistling sound, during the flight of the shuttlecock ball. The channels may have a variable diameter along their direction of extent to produce a whistling sound of a particular frequency. The channels preferably extend through the striking cap, ie both the core impact cap and the application, and a part of the fixing part of the flying basket adjacent to the striking cap, so that a draft of air is generated through the striking cap during the flight of the shuttlecock ball.

In a further preferred embodiment of the invention it is provided that the fixing part has a cavity in the interior, which optionally has a separate filler and / or a ball and / or encapsulation material of the first encapsulation layer. In the present invention, the fixing part arranged at the tapering end of the jacket is preferably a cylindrical circumferential band of defined height. Preferred heights are in particular in the range of 0.5 cm to 1, 5 cm, more preferably 1 cm in height. Particularly preferably, the fixing part on the side facing the jacket on a substantially circular, planar or concave or convex curved base. The base surface of the cylinder opposite top surface, however, is open. As already stated above, before the arrangement of the encapsulation layer or encapsulation layers, the fixing part is first introduced into the core impact cap. The core impact cap has a receiving area, for example in the form of a depression. This receiving area corresponds to the outer shape of the cylindrical fixing part and can either be inserted only so deep that the inlet depth corresponds to the height of the cylindrical fixing part, so the fixing part can be completely absorbed. Alternatively, the receiving area may be in the form of a through opening passing through the core impact cap.

If the core impact cap is designed to be closed, then, after the formation of the encapsulation layers, a cavity remains in the interior of the fixing part and thus in the interior of the impact cap. This can advantageously lead to increased elasticity of the impact cap. Alternatively or additionally, the cavity serves to receive a locking means of the application. For this purpose, the core impact cap on an opening, which is arranged in the region of the receptacle. The application has a corresponding longitudinally extending bulge with a taper, wherein the diameter of the bulge is smaller than the diameter of the cavity. The opening of the core impact cap in turn has a diameter which is less than the diameter of the bulge. If the bulge is introduced into the opening of the core impact cap, the taper of the bulge of the application is arranged at the level of the opening and the application thus locked in the impact cap.

In this embodiment, it is further preferred that the elongate bulge has an at least partially permeable channel. This channel is used to generate an air flow through the ball and thus the whistling sound generation and / or the arrangement of a weight (mass with a higher density than application). Advantageously, the arrangement of the weight and in particular its position leads to an influence on the center of gravity of the shuttlecock ball and thus to a specific influencing of the flight characteristics.

In another embodiment, a ball can be arranged in this cavity before insertion of the fixing part in the core impact cap. This can have the effect that, on the one hand, the weight of the shuttlecock ball, in particular the striking cap, is increased. In addition, this weight is not fixed, but rather has a certain movement tolerance. The ball and thus the weight is displaced within the fixing part. This can positively affect the flight characteristics of the shuttlecock.

Likewise, a separate filling body can be arranged in the cavity of the fixing part, which completely fills the cavity. It is irrelevant whether or not the core impact cap has an opening for encapsulation.

In a further embodiment, the fixing part which is open at the top is introduced into a core impact cap provided with a through-opening. In the formation of the first encapsulation layer by means of dipping, the cavity of the fixing pin is inevitably filled with the encapsulation material of the first encapsulation layer. This can advantageously the flight characteristics, in particular the rebound resilience of the striking cap, influence. By selectively selected execution or filling forms of the cavity in the interior of the fixing part thus the flight characteristics, in particular the rebound resilience of the shuttlecock can be selectively adjusted.

In a further embodiment of the invention, it is preferred that at least one outer encapsulation layer has a peripheral groove, and in this groove a trim ring can be arranged. The diameter of the groove is greater than or equal to the inner diameter of the trim ring. Under circumferential groove is to be understood in the present invention, a depth relief or a contour of the impact cap of the shuttlecock, which extends circumferentially around the impact cap. This circumferential groove is designed so that it can accommodate a trim ring. The height of the trim ring and the width of the groove, the shape of the groove and the shape of the inner portion of the trim ring and the diameter of the groove and the inner diameter of the trim ring correspond to each other. This means that in particular the diameter of the groove is chosen so that a particular elastic trim ring can be guided over the impact cap and is held in the groove, so you can not slip out without targeted external influence. The trim ring is preferably made of colored, luminous and / or translucent rubber. Thus, the trim ring is preferably functional. Depending on the configuration of its size and / or the material from which it is made, it can positively influence the flight characteristics and / or the visual perception by the player through increased resistance and / or specific weight and / or visually perceptible properties.

It is advantageous if the trim ring also has one or more channels which extend perpendicular to a diameter of the trim ring and are embedded in a defined proportion in the trim ring or this, in the form of an opening, perpendicular to the diameter. The channel (s) may be used to receive luminescent material in the form of rods, creases, rings, bands, potting or the like, and thus positively affect perceptibility by the player. If, however, the channels are designed as openings passing through the trim ring, they can generate noises, in particular a whistling sound, during the flight of the shuttlecock ball and thus give an acoustic signal, which is added to the visual perception of the shuttlecock ball. In an alternative embodiment, ornamental rings described above can also be arranged on impact caps, which do not have a groove for receiving the ornamental ring. In such a case, the trim ring can advantageously be arranged later on existing impact caps. The diameter of a decorative ring is in this case to be adapted such that it is smaller than the circumference of the striking cap, but the difference can be overcome by a stretchability of the material of the trim ring and the trim ring is fixed by tension on the striking cap.

In a particular embodiment of the invention it is preferred that the jacket has an opening opposite the fixing part, which spans a surface and each point of the surface by rotation of respectively 22.5 °, 45 °, 90 °, 120 ° or 360 ° about an axis of rotation is translatable, with the axis of rotation through the center of the surface perpendicular to this. Thus, the jacket on the opposite side of the fixing part spans a highly symmetrical surface. From a triangle, through a square and rectangle, to an octagon, hexagon, or sedezigon, all the way to a circular shape, this can include almost all point-symmetrical geometrical shapes. However, particularly preferred are substantially square and / or triangular shapes, since they have the smallest air resistance. Essentially in this context means that in particular the sides of the regular shapes, that is to say, for example, the sides of the triangle and / or the square, do not necessarily have to be rectilinear, but preferably have concave or convex curvatures. In addition, the corners, ie the points at which adjacent sides of the geometric figure meet, can be both round and pointed. Pointed shapes show the corners, especially when two adjacent sides have a maximum of a concave curvature and converge at the respective corner pointed. Alternatively, however, the corners can also be designed as curves. This is the case in particular when, for example, concave-shaped side parts have a further turning point in a region adjacent to the corner, or the sides have a convex curvature. Also preferred are all embodiments between these two described extreme embodiments of the invention. In a further embodiment of the invention, it is preferred that the flying cage has segment-forming longitudinal webs and transverse webs at least in one region, wherein the longitudinal webs extend longitudinally from the fixing part to an edge and are connected via the transverse webs, optionally at least those located at the flight cage opening Transverse webs are formed wavy. Thus, segments form between longitudinal and transverse webs. These segments form a trapezoidal or a rectangular area depending on the configuration or shaping of the shell. In turn, the segments can be subdivided by segment webs, which likewise run like the longitudinal webs from the fixing part to the edge of the shell. The transverse webs are arranged such that they intersect on the one hand, the longitudinal webs and on the other hand rotate parallel to the edge of the lateral surface, the lateral surface. As well as the longitudinal webs and the transverse webs are preferably uniformly spaced from each other. Two adjacent transverse bridges each form one floor. In principle, it is preferred that the segmentations begin at a predefined distance from the impact cap of the flying basket. This means that the first crosspiece is arranged at a defined distance from the impact cap. This distance is preferably 20 mm (± 3 mm), to be measured on a longitudinal web starting from the striking cap. At the first crosspiece preferably three so-called base stages are arranged. These base stages are characterized by the fact that all segment webs are adjacent to each other at the same distance. It is preferred that at least one, preferably eight, further stages follow this basic stage. The segments within the further stages preferably divide into two areas, one area having twice the number of segment bars than the adjacent one. By this arrangement of the segment webs, a different air resistance of the two segment areas can be generated. This in turn leads to the flight of the ball to a deflection of the air flow and turn to a rotation of the shuttlecock ball. The transverse webs are preferably arranged at a distance of 6 mm (± 3 mm) from each other. This distance of 6 mm (± 3 mm) also defines the height of each step. At the outermost stage is preferably followed by a final stage, which has a height of one third of the other stages. Depending on the further steps following the base steps, the total length of each longitudinal web from the fixing part to the edge of the longitudinal web thus preferably corresponds to 33 mm to 55 mm (± 3 mm) or the length of a longitudinal web starting from the striking cap to the edge of the Longitudinal bar 43 mm to 65 mm (± 3 mm). The length of the longitudinal webs and in particular the number of further stages significantly influences the airspeed as well as the rotation of the flying basket during the game. The shorter the flight cage is configured, that is, the fewer the further stages are arranged on the base stages, the faster the ball flies.

However, the speed, but also the other flight characteristics, in particular the rotation, can also be influenced by the shape of the shell as a whole. Therefore, in a further embodiment of the flying cage, it is preferred for the jacket to be cylindrical, angled or flared in a region spaced from the impact cap. In other words, the jacket is conically shaped, at least in an area adjacent to the impact cap, at a defined distance from the impact cap can then deviated from the basically conical or conical shape of the shell or the slope of the cone side can be increased or decreased. An axis of rotation of the cone described means that, starting at this defined distance from the impact cap, the jacket extends, for example, parallel to the axis of rotation. This would result from this distance, a cylindrical shape of the shell, which has a greatly reduced air resistance and thus a higher airspeed result. Another possibility would be that, starting at the defined distance from the striking cap, the jacket is tilted more away from the axis of rotation toward the outside, ie away from the axis of rotation, or towards the inside, ie towards the axis of rotation. Such a flared or angled shape of the shell also affects the airspeed. In particular, a strongly outwardly flared shape of the shell could lead to increased air resistance and thus to a reduction in speed while increasing the rotational forces. The latter embodiment would result in a more stable trajectory. The properties are particularly enhanced when the modified shape of the shell starts relatively close to the impact cap. Therefore, it is preferred that the formation of the jacket, in particular the exhibition to the outside, before the fourth stage, ie before the first further stage, in particular before the segmentation, particularly preferably starts directly on the striking cap.

The invention is also not limited to the embodiments shown here. Rather, it is possible to implement variants of the means and features mentioned further variants of the invention. Thus, for example, by combining the suitable features, a shuttlecock perfectly designed for the requirements of a professional player or of a beginner player can be provided.

Detailed description of the invention

FIG. 1 shows a shuttlecock 10 according to the invention in a sectional view to the main axis of the shuttlecock 10. The shuttlecock 10 can be subdivided into two sections, namely the striking cap 20 'and the shuttlecock 30. The striking cap 20' in turn comprises a core striking cap 21 which is surrounded by an encapsulation 20 is surrounded. This encapsulation 20 is double in the illustrated embodiment and therefore consists of two encapsulation layers, a first encapsulation layer 22 which adjoins directly to the core impact cap 21 and a second encapsulation layer 23. The encapsulation layers 22 and 23 can be applied in the same way, be prepared for example by dipping or spraying. You can either use the same material, which preferably comprises rubber, rubber, latex or other elastomers. However, the composition of the individual encapsulating layers 22 and 23 may be different from each other. Likewise, the thicknesses and densities of the encapsulant layers 22 and 23 may differ. In the illustrated embodiment, the encapsulation 20 has only two encapsulation layers 22, 23, but in other embodiments of the invention the encapsulation 20 may also have further, preferably up to four, encapsulation layers. In the illustration, it is clear that the encapsulation 20 completely encloses the core impact cap 21, as well as the fixing part 35 of the flight basket 30 introduced in the core impact cap 21; moreover, parts of a shell 31 are also enclosed by the encapsulation 20.

In the core impact cap 21 of the fixing part 35 of the flying basket is introduced. For this purpose, the core impact cap 21 has a cavity in the interior, which corresponds in shape and size of the fixing part 35. The fixing part 35 has an upwardly open cylindrical shape. If the fixing part 35, as in the illustrated illustration of FIG. 1, is introduced into the core striking cap 21, a cavity 36 is formed in a first embodiment. The cylindrical fixing part 35, as in the illustration of Figure 1, have a concave base surface. At this base, the jacket 31 of the air basket 30 is arranged circumferentially. At least in the area close to the fixing part, the jacket 31 has a conical shape, the fixing part 35 being arranged at the tip of the cone. Starting from the fixing part 35, in the selected illustration of FIG. 1, the jacket 31 opens far as far as a shuttle cage opening 39. In the area of the lift cage opening 39, the jacket 31 shows the largest diameter.

The first embodiment of an aircraft basket 10 according to the invention shown in FIG. 1 is optimized in particular with respect to the rebound resilience. This is achieved inter alia by the cavity 36 in the interior of the fixing part 35, which arises when the fixing part 35 is inserted without prior filling in the core impact cap 21. Depending on the configuration of the encapsulation layers 22 and 23, the elasticity of the encapsulation 20 is further increased by the remaining cavity 36. The impact force, which is applied to the striking cap 20 'by means of a suitable racquet, is discharged through the cavity by means of air pressure to the concave shaped base surface of the fixing part 35. Figure 2 shows a shuttlecock 10 according to the invention in a further embodiment, which substantially corresponds to the representation of Figure 1. The embodiment of the shuttlecock ball 10 shown in FIG. 2 also has a jacket 31, which is arranged on a fixing part 35. This fixing part 35 is also inserted into a core striking cap 21 as in FIG. In contrast to the embodiment shown in Figure 1, the striking cap 20 'in the second embodiment possibility above the fixing part 35 an opening. During production of the first encapsulation layer 22 arranged on the core impact cap 21 by means of dipping or spraying, the cavity 36 in the interior of the fixing part 35 was filled with the mass of the encapsulation layer 22 through the opening of the core impact cap 21.

Another difference from the first embodiment is that the encapsulation consists of only a first encapsulation layer 22. This also has a groove 24, so a depth profile. This groove 24 is formed to receive a trim ring 40. Shape and size of groove 24 and trim ring 40 correspond to each other so that they can optimally interlock and the trim ring 40 is fixed.

The trim ring 40 may, as in the illustration of Figure 2 additionally have at least one channel 41. In the embodiment shown in Figure 2, the trim ring 40 has two parallel types of channels 41. These channels 41 extend along the flight direction, ie perpendicular to a diameter or perpendicular to the direction of rotation of the trim ring 40 to the outer encapsulation layer 22. The trim ring 40 has two kinds of channels 41, that is, a channel, which is designed as passing through the ornamental ring 40 openings and another type of channel 41, in which the openings are embedded only in a certain part in the trim ring 40.

The differences between the second embodiment and the first embodiment shown in FIG. 1 are aimed in particular at two functions of the shuttlecock ball 10. The arrangement of the encapsulating material 22 in the interior of the cavity 36 of the fixing part 35 influences the weight of the shuttlecock ball 10 and thus the airspeed, but also the resilience of the striking cap 20 'is strongly influenced by the encapsulating material. The arrangement of the ornamental ring 40 on the striking cap 20 ', however, has an effect on the flight characteristics only in relation to the increased aerodynamic drag. Rather, an ornamental ring 40 arranged in this way can increase the perception of a shuttlecock ball 10 during the game, in particular during the flight. This can be ensured by the fact that on the one hand, the channels 41 passing through the trim ring 40 as a result of the passage of air during flight produce a whistling sound and thus give an audible signal. On the other hand, the channels can record visually perceptible materials. This can be, for example, in the form of glow sticks, but also of optical dyes, fluorescent or luminous materials in the form of tapes and / or functional materials, which are arranged by casting, injection molding, dipping or the like within the channels.

FIG. 3 likewise shows a longitudinal sectional illustration of an inventive flight cage 30. The third embodiment shows, similar to the embodiment in FIG. 1, a striking cap 20 'which has an outer encapsulation layer 23 and a further, a first encapsulation layer 22. Also as described in the first embodiment, the first encapsulation layer 22 adjoins the core impact cap 21. The core impact cap 21 shown in FIG. 3 is an upwardly closed mold. This means that a fixing part 35 can be introduced into the core-striking cap 21 before the encapsulation layers 22 and 23 are arranged without encapsulating material from the first encapsulation layer 22 entering the cavity 36 in the interior of the fixing part 35 in the subsequent encapsulation. In contrast to the first embodiment of the shuttlecock ball 10, a separate packing is introduced in the third embodiment in the interior of the fixing part 35. This packing corresponds in shape and size to the resulting cavity 36. To achieve this arrangement, the packing must be introduced into the cavity 36 before the fixing member 35 is inserted into the core impact cap 21. As an alternative to introducing a virtually tightly closing separate filling body, a ball, not shown here, with a defined weight and a defined size can likewise be introduced into the cavity 36. Such a ball can then be at most as large in diameter as the diameter of the fixing part, but it is preferred that the diameter of the ball is significantly smaller than the diameter of the cylindrical basic shape of the fixing part 35.

Another difference to the first embodiment of the invention lies in the shape of the jacket 31st This has as well as in the first embodiment has a substantially conical shape. The slope of the cone, so the inclination of the lateral surface, is However, not the same from the fixing part 35 to the airbag opening 39. On the contrary, the jacket 31 has a greater deflection toward the outside in a region spaced from the fixing part. The jacket 31 is shown at this area much further than in the cap close range. In the embodiment shown here begins the stronger exhibition of the lateral surface in the area where a continuation of the outer impact cap 20 'in the direction of the jacket 31 would cut the lateral surface.

The embodiments in FIG. 3 primarily aim at the flight characteristics of the shuttlecock 10. If the cavity 36 is filled with a separate filling body, the rebound resilience and weight of the shuttlecock ball 10 can be greatly influenced by the material of the separate filling body. Thus, in particular the speed of the shuttlecock 10 is influenced, in particular increased. If, on the other hand, a movable ball is arranged in the interior of the cavity 36, in addition to the weight increase by the ball, a shift in the weight can be achieved.

A shape of the lateral surface 31, as shown in the third embodiment, in particular increases the aerodynamic drag of the shuttlecock 10 during flight. By increasing the air resistance of the shuttlecock 10 can be quasi braked in flight. In this case, the air resistance increases and as a result the braking effect at an elevated angle, so with increasing flight cage opening 39. The maximum possible air resistance is achieved when the shell 31 is arranged in the issued area almost parallel to a circular base of the striking cap 20 '. Then also the hoistway opening 39 is maximum. Depending on the design of the lateral surface with respect to a segmentation shown later, the increase in air resistance can additionally lead to a greater rotation of the flight cage 10 in flight. This in turn has a positive effect on the stabilization of the trajectory of the shuttlecock ball 10. The third embodiment shown is therefore a suitable especially for beginners embodiment of a shuttlecock 10 of the invention.

For better illustration, a three-dimensional drawing of a further embodiment, in particular an embodiment of the flight cage 30, is shown in FIG. The illustrated flight cage 30 has a fixing part 35 and a cavity 36 located therein. The fixing part is designed in a cylindrical shape, wherein in the region of the base surface of the fixing part 35, a jacket 31 connects. The jacket is by means of a plurality of longitudinal webs 32, which extend from the fixing part 35 to the shuttle opening 39, and divided transversely to the longitudinal webs 32 transverse webs 33 into segments. The transverse webs 33 start at a predetermined distance from the fixing part 35. The transverse webs 33 are executed parallel to one another. Two transverse webs 33 each delimit a step. Starting from the fixing part 35, three so-called base stages are initially formed. Additional stages are arranged at these base stages. This can be both a further stage as well as several, in particular as shown, five further stages. The individual segments can have further, not shown subdivisions in the form of segment bars. A special feature of the air basket 30 shown here is the jacket shape. In contrast to the outwardly shaped shell shape shown in FIG. 3, a jacket 31 is shown in FIG. 4 which, in the region of the segmentation with completion of the third base stage, no longer has a conical outward appearance, but rather extends cylindrically as far as the flight cage opening 39. This division of a cylindrically shaped casing part and a conically shaped casing part can likewise take place outside the segmentation, that is to say in the region between the fixing part 35 and the first transverse web 33. The earlier the alternative shaping of the jacket takes place, the stronger is the influence of the jacket shape on the flight characteristics of the flight cage 30. If a shuttlecock 10 is equipped with a flight cage 30 shown in FIG. 4, it is characterized in particular by a very low air resistance and thus by an increased altitude Flight speeds off.

FIG. 5 shows three boundary forms of a particularly preferred embodiment of an aerial basket 30. The plan view shows a fixing part 35, to which a jacket 31 connects. This has longitudinal webs 32 and transverse webs 33. The forming segments are in turn subdivided by segment webs 34. Although the pattern of longitudinal webs 32, segment webs 34 and transverse webs 33 proceeds uniformly from the first transverse web 33 over the entire lateral surface, only individual regions are completely sketched in the drawings of FIG. 5 for better illustration.

As already shown and explained in the embodiments of FIGS. 1 to 4, the shape of the jacket 31 broadens starting from the fixing part 35. At the end of the jacket 31 opposite the fixing part 35, the shuttle opening 39 is formed. This in turn biases a surface 37. The surface is shaped as a regular figure. Particularly preferred are forms which are defined by rotation about an axis in the center 38 of the Fixing part 35 and the center 38 of the surface 37 extends, is interconvertible at a certain angle. Particularly preferred are geometric shapes such as triangles, which result from rotation at an angle of 120 °, squares, which in turn require a rotation of 90 ° about the axis of rotation, as well as hexagons and most other geometric shapes to a regular circle. Shown in FIG. 5 is a surface 37 which essentially spans a triangle. The sides 37a of the triangle are in each case of the same length and can be concave, as shown in partial illustration A, in a straight line, as shown in partial illustration B, or else convexly, as shown in partial illustration C. Adjacent sides converge at the corner points 37b of the geometric shape, respectively. Here are also given several design options. Favor are both tapered sides 37a, which then meet in the corner 37b in exactly one point. The two adjacent sides 37a then preferably enclose an angle between 5 ° and 90 °. An alternative embodiment of the geometrically shaped surface 37 is a more or less rounded configuration.

FIG. 6 likewise shows the plan view of a flight cage 30. The geometric shape of the surface 37 shown here is that of a square. FIG. 6A shows an embodiment which has moderately concave-shaped sides 37a of the geometric shape, with two adjacent sides 37a each tapering in a corner 37b. The included angle is about 15 °. A very extreme, but still preferred embodiment is shown in Figure 6B. The likewise square basic shape of the surface 37 has very strongly concave-shaped sides 37a, each of which has two points of inflection to the outside, so that two adjacent sides 37a converge in the corner 37b almost in a perfect semicircle and barely include a measurable angle.

The formations of the flight baskets 30 shown in FIGS. 5 and 6 in particular influence the airspeed and the rotational capability and thus the stability of the trajectory of a shuttlecock according to the invention, owing to the aerodynamic drag that forms. The embodiments 5A, 6A and 6B show because of the strongly concave sides 37a embodiments, which would be characterized by particularly high airspeed. In contrast, the use of an aircar 30 shown in Figure 5C results in a rather slower, very stable flying shuttlecock 10. FIG. 7 shows the shuttlecock 10 according to the invention in a further preferred embodiment. The basic construction of the shuttlecock ball 10 shown in FIG. 7 essentially corresponds to the basic structure of the embodiments already described.

The flight cage 30, which comprises a fixing part and a jacket is positively and / or cohesively arranged in a striking cap 20 '.

The striking cap 20 'in this case comprises an encapsulation 20, which was obtained in particular by encapsulation of the fixing part in an injection molding tool. In an embodiment shown, the encapsulation 20 comprises the core impact cap and at least one encapsulation layer. The encapsulation 20 has on the side facing away from the jacket a recess 25 for receiving an application 50. The recess corresponds to the negative image of the application 50 and may comprise a recess for receiving a pin for better retention, the pin being arranged on the side of the application 50 facing the encapsulation 20, in particular a part of this, as shown in FIG , Furthermore, the encapsulation 20 above, ie on the side facing away from the jacket side of the fixing part on an opening 53.

Adjacent to the surface of the recess 25 is an application 50, which is connected to the encapsulation 20 in a material and / or form-locking manner. The application 50 is made of natural materials such as rubber, or of thermoplastic materials such as latex and silicone. The application 50 has a bulge 51, which extends longitudinally in the direction of the fixing part and also has a taper 52, ie a region in which the diameter of the bulge is reduced. The elongated bulge 51 itself has a diameter which is greater than that of the opening 53.

The bulge 51 is placed in the striking cap 20 'in such a way that it is arranged in the cavity 36 of the fixing part. For this purpose, the bulge 51 of the application 50 is guided through the opening 53, so that the taper 52 is arranged at the level of the opening 53. Due to the ratios of the diameters of the bulge 51, opening 53 and taper 51 to one another, a firm locking of the application 50 on the encapsulation 20 is created. Within the impact cap further modules, such as elastic modules 42, weights 43 or signal transmitters (not shown) may be arranged. For manufacturing reasons, these are preferably arranged at the boundary between the encapsulation 20 and the application 50 and / or in the application 50 itself.

Elasticity modules 42 have the function to increase the rebound resilience of the shuttlecock ball 10. They are made of materials which have a higher elasticity than the encapsulation 20 and / or the application 50.

Weights 43 influence specifically the center of gravity and thus the flight characteristics of the shuttlecock 10. They are preferably arranged inside and / or at the bulge 51 of the application 50.

Signalers are visible at least in part on the surface of the striking cap 20 '. This can be, for example, a nubbed, preferably reflective, fluorescent or colored layer which is arranged between the application 50 and the encapsulation 20. In this embodiment, the application 50 has perforations which are designed and arranged such that the studs pass through the application at least to a certain extent and are visible when viewed on the surface of the application 50.

The invention is not limited to the embodiments shown here. Rather, it is possible to realize by variations of the means and features mentioned further variants of the invention.
