[0007] The projection with a locking element arranged between the free end and the fixed end of the projection is not disclosed in US patent application US2219156A (see US patent application US2219156A, Fig. 1, projection 2, locking element 3) and US patent application US20100107946A1 (see US patent application US20100107946A1, Fig. 1, projection 2, locking element 3); furthermore, in US patent application US2219156A, the locking element of the first hub component is arranged on the use side of the second hub component, not in the locking element recess of the second hub component spoke through the relative rotation of the hub components. Figure 2 Utility model content

[0008] ​​​​The utility model discloses a wheel hub (Felge) with a tire, comprising a first wheel hub part and a second wheel hub part. In a view normal to these, the wheel hub part (Felgenteil) has a generally circular cross section, which is suitable for a circular tire. The first wheel hub part comprises a concentrically arranged first opening The second wheel hub part comprises a concentrically arranged second opening. These openings are used to rotatably mount the wheel hub parts around a wheel axle (Radachse).

[0009] The wheel hub parts can be combined together in such a way that a single wheel axle extends through the first opening and through the second opening. The wheel hub parts can be arranged relative to each other with a wheel hub spacing (Felgenabstand) measured in the direction of the wheel axle being greater than or equal to zero.

[0010] The wheel hub parts can be moved relative to each other along the wheel axle, provided that the relative movement between each other is not locked by the locking element described below.

[0011] The primary task solved by the utility model is to design the wheel hub parts to be replaceable (austauschbar). The utility model is realized by the following way, i. e. the first wheel hub part comprises at least one protrusion extending in the direction of the wheel axle in the first spoke area, the protrusion can be introduced (einbringbar) into the notch (Ausnehmung) of the second wheel hub part, wherein the protrusion comprises a locking element at the free end of the protrusion or between the free end and the fixed end (angeschlossenes Ende), and the locking element can be engaged with the second wheel hub part.

[0012] The protrusion is arranged in the spoke area and / or the wheel hub flange (Felgenhorn) and / or the wheel hub side (Felgenflanke). The user can see the spoke area, especially the outer spoke area. The user can check whether the connection formed by the locking element introduced into the notch has been loosened.

[0013] The protrusion connected with the first wheel hub part comprises a free end and a fixed end, and the fixed end of the protrusion is connected with the first wheel hub part.

[0014] The connection formed by introducing the locking element into the notch is loosable. For example, the user can stick the locking element in the notch, so that the connection is not loosable. The locking element can prevent being opened.

[0015] According to the wheel hub of the utility model, the protrusion extends radially (radial) or tangentially (tangential) relative to the first wheel axle.

[0016] The protrusion can be cuboid in shape. The cuboid can extend radially or tangentially and longitudinally with respect to the hub axis from the hub surface defined by the spoke The protrusion can extend radially or tangentially and longitudinally with respect to the hub axis from the hub side or the hub flange.

[0017] The protrusion can extend radially or tangentially and longitudinally with respect to the hub axis from the hub side or the hub flange.

[0018] The protrusion can extend radially or tangentially and longitudinally with respect to the hub axis from the hub side or the hub flange.

[0019] The design of the recess makes it possible for the protrusion and the locking element to be introduced into the recess.

[0020] The locking element can be a separate element. The locking element can be designed in one piece with the protrusion.

[0021] According to the hub of the utility model, by rotating the first hub element about the hub axis and with respect to the second hub element, the locking element arranged at the free end of the protrusion or between the free end and the fixed end of the protrusion can be engaged with the second hub element.

[0022] Possible embodiments regarding the design of the protrusion, the locking element and the recess will be discussed in the following description of the drawings.

[0023] According to the hub of the utility model, the protrusion can be introduced into the recess defined by one or two spokes.

[0024] The recess can be designed on one spoke. The cavity between two spokes can be regarded as a recess.

[0025] According to the hub of the utility model, the locking element can be introduced into the locking element recess of the second hub element arranged on the spoke.

[0026] The utility model disclosed herein also solves a second task, namely the replacement of solid rubber tires. In the prior art, solid rubber tires for scooters and similar vehicles exhibit very low elasticity and thus cannot be stülpen on the hub. According to the prior art, the tires are injected (aufgespritzt) or cast (aufgegossen) on the existing one-piece hub. A worn-out or unusable tire means that the inseparable hub and wheel combination manufactured according to the prior art must be disposed of. In particular, since the combination of wheel and hub consists of a plurality of materials, recycling is not possible.

[0027] By introducing the locking element into the locking element recess, the hub components can be pressed against one another. For example, the locking element can comprise a first contact surface which is arranged at right angles to the wheel axis, and the locking element recess can comprise a second contact surface which is inclined with respect to the wheel axis (or vice versa), such that, by introducing the locking element into the locking element recess, a continuously increasing pretension is generated, by means of which the hub components are pressed against one another.

[0028] The locking element and the locking element recess can comprise a detachable snap-in connection. By introducing the locking element into the locking element recess, the locking element is snapped into the locking element recess.

[0029] The task of the present application is to make it possible for a tyre to be removed from a hub and to be replaced by a new tyre.

[0030] According to the hub of the present application, the hub components comprise a first tyre clamping surface and a second tyre clamping surface, wherein the tyre is held or clamped by means of the tyre clamping surfaces.

[0031] As explained at the outset, the hub according to the present application comprises at least two hub components which are detachably connected to one another. An intermediate element can be arranged between the hub components. The connected hub components hold the tyre in a formschlüssig and / or clamped manner. By loosening the connection which holds the hub components and moving the hub components away from one another, a worn tyre can be replaced by a new tyre. The hub according to the present application can then be reassembled.

[0032] According to the hub of the present application, the first tyre clamping surface and the second tyre clamping surface are mirror-inverted with respect to a mirror plane axis which is arranged at right angles to the wheel axis.

[0033] According to the hub of the present application, a further locking element prevents the first hub element from rotating with respect to the second hub element.

[0034] According to the hub of the present application, the tyre comprises at least one tyre recess, and at least one of the hub components comprises at least one tyre connection protrusion which engages with the tyre recess.

[0035] The tire recess and the tire connecting protrusion are used to further connect the tire with the at least one hub part. The tire recess can be designed as a recess extending radially on the tire wall, into which a tire connecting protrusion, likewise designed radially, can be introduced. In a preferred embodiment, the tire, on its two sides, the tire flanks which come into contact with the hub part, comprises at least one tire recess and a tire connecting protrusion which matches the hub part.

[0036] The utility model also relates to arranging light sources such as LEDs in or on the hub.

[0037] According to the prior art, hubs with light sources such as LEDs are increasingly popular, especially for children's ride-on devices such as scooters, pedal cars and the like. The light sources can be switched on when the hub is rotating and switched off when the hub is stationary, thus demonstrating the rotational movement of the hub to the child.

[0038] According to the prior art, the hub is designed at least integrally with the light source. For example, a damaged light source cannot be separated from the hub.

[0039] The task of the utility model disclosed here is to arrange LEDs detachably in or on the hub. This task can also be solved without relying on a mechanical connection of the hub parts mentioned above.

[0040] A first solution provides that the at least one hub part comprises an LED element.

[0041] The hub part can be designed as an LED element.

[0042] A second solution provides that the LED element is arranged between a first hub part and a second hub part.

[0043] The LED element is fixed directly or indirectly by the hub parts. If it is fixed indirectly by the hub parts, a further element, such as a tire, is arranged between the hub parts and the LED element.

[0044] The at least one hub element can comprise a recess or a protrusion on its surface facing the LED element for detachably mounting the LED element.

[0045] A third solution provides that the LED element is mounted on the outside of the hub part.

[0046] The hub part can comprise a recess or a protrusion for detachably mounting the LED.

[0047] The three solutions mentioned above arrange the LED in a tire which is fixed by the hub parts. This has the advantage that the LED is protected by the tire.

[0048] The LED is mentioned here as an example of a light source, since the use of LEDs is advantageous compared to other electric light sources. However, the use of other electric light sources, such as light bulbs, is by no means excluded.

[0049] The LED element can be connected to the at least one hub component directly or indirectly and thus via another element. Depending on the different suggestions of the solution, the connection can be releasable or non-releasable. The connection can be made by mechanical connection means or adhesive connection means (Verbindungsmittel). For example, the non-releasable connection between the at least one hub component and the LED element can be an integral design of the LED element and the hub component. For example, the integral design of the LED element and the hub component can be the production of the LED element and the hub component as a Spritzgusselement.

[0050] The LED element comprises an LED as a light source and a generator or a battery as an electrical source. In particular, the conduction of the current from the battery to the LED can be controlled by the movement of the hub component. For example, the generator can be driven by the relative movement between the wheel axle and the hub component. The generator can supply power to the LED only when there is a relative movement between the wheel axle and the hub component.

[0051] One LED element or a plurality of individual LED elements can be arranged in such a way that the light is emitted radially with respect to the hub component or the wheel axle. The emitted light can be emitted to the surroundings, for example, through the tire.

[0052] LEDs which emit light in the longitudinal direction can emit light to the surroundings directly or indirectly via the hub component.

[0053] The LED element can consist of a plurality of LEDs arranged on a strip. The light strip can surround (umlaufend) the at least one hub component or the wheel axle at a certain distance.

[0054] According to the hub of the present application, the at least one hub component or another element is made of a light-transmitting material, and the other element is arranged in the hub.

[0055] Part of the light quantity emitted by the LED can be emitted to the surroundings via part of the surface of the hub. The part of the light quantity can be emitted in different parts of the light quantity. According to the common theory, this can be used to display patterns on the hub with light.

[0056] Light-transmitting elements with light-focusing or light-scattering properties, such as crystals or lenses, can be installed in the hub in order to emit light into the hub or into the surroundings.

[0057] The present application will be further explained with reference to the following embodiments shown in the accompanying drawings.​ Attached Figure Description

Likewise, not all elements in the drawings are marked with reference signs.

[0070] Regarding the drawings Figure 1 , 2 :

[0071] Figure 1 A wheel hub with a tire 1 is shown. The wheel hub comprises a first wheel hub part 2 and a second wheel hub part 3.

[0072] Figure 2 A view of the second wheel hub part 3 is shown.

[0073] The first wheel hub part 2 has a circular first surface extension 9. The surface extension is at a 90 degree angle to an axle 4. The second wheel hub part 3 also has a circular second surface extension 10, which is at a 90 degree angle to the axle 4. The axle 4 extends through a first opening 5 in the center of the first wheel hub part 2 and a second opening 6 in the center of the second wheel hub part 3.

[0074] The first wheel hub part 2 is rotatably mounted on the axle 4 through the first opening 5 and the second wheel hub part 3 is rotatably mounted on the axle 4 through the second opening 6.

[0075] The first wheel hub part 2 and the second wheel hub part 3 can be arranged at a wheel hub distance 7. The wheel hub distance 7 can be changed by moving the wheel hub parts relative to each other if the wheel hub parts are not in an upright connection. Figure 1 The wheel hub distance 7 is symbolically marked. The wheel hub distance 7 can be zero when the wheel hub parts are assembled.

[0076] The first wheel hub part 2 comprises at least one protrusion 8 extending in the direction of the axle 4. The protrusion 8 is arranged on the side of the first wheel hub part 2 facing the second wheel hub part 3.

[0077] The second hub component 3 includes a notch 9 located in the extension of the second surface. The notch 9 is designed so that the protrusion 8 can be introduced into the notch 9.

[0078] Figure 1 The illustrated embodiment includes multiple protrusions 8 and multiple notches 9. In the accompanying drawings, only some of the protrusions 8 and notches 9 are labeled to maintain clarity.

[0079] A locking element 11 is arranged between the free end 10 and the fixed end of the protrusion 8.

[0080] Figure 1 In the embodiment shown, the locking element 11 is placed on the side of the second hub component 3 facing the first hub component 2 and engages with the second hub component 3.

[0081] exist Figure 1 In the illustrated embodiment, the locking element 11 is arranged by introducing a protrusion 8 into a notch 9 on the side of the second hub component 3 opposite to the first hub component 2. The locking element 11 engages with the second hub component 3 by rotating the first hub component 2 about the axle 4 (clockwise, for example) and relative to the second hub component 3. The locking element 11, positioned in this way, extends parallel to the side of the second hub component 3 opposite to the first hub component 2, thereby establishing a connection between the first hub component 2 and the second hub component 3. This connection prevents the hub components from moving relative to each other and in the direction of the axle 4.

[0082] Figure 1 The illustrated embodiment, in a preferred embodiment, includes a plurality of protrusions 8. Each protrusion 8 is arranged to project from the side of the first hub component 2 facing the second hub component 3. The protrusions 8 are arranged radially around the wheel axle 4 on the side of the first hub component 2 facing the second hub component 3.

[0083] Each protrusion 8 of the first hub component 2 has a matching notch 9 in the second hub component 3. The protrusions 8 and notches 9 have the same cross-section, and with this preferred design shown here, each protrusion 8 can be introduced into each notch 9.

[0084] Such a notch 9 can be designed to be located in the second hub component 3, which is designed as a disc (Scheibe), or in the spokes of the second hub component 3. Figure 1 This illustrates an embodiment with a unique (ansprechend) design, in which the notch 9 is designed as a notch defined by two adjacent spokes.

[0085] As mentioned above, the locking element 11 is positioned on the side of the second wheel hub part 3 facing away from the first wheel hub part 2. This side of the locking element 11, with which the locking element engages, is designed with a locking element recess 12 in the spoke of the second wheel hub part 3.

[0086] The above description of the figures relates to the first task faced by the present application.

[0087] To solve the second task faced, the wheel hub part comprises a first tire clamping surface 13 and a second tire clamping surface 14. The tire 1 is fixed by the tire clamping surfaces, or clamped after a pretensioning force has been applied. By assembling the wheel hub parts (see arrow 15) and connecting the wheel hub parts with the locking element 11, the tire 1 is received by the wheel hub parts. In this way, the tire 1 and the wheel hub parts are mounted so that they can be rotated relative to the wheel axle 4 and around the wheel axle 4. In this way, the combination of the wheel hub parts and the tire 1 can be inserted onto the wheel axle 4.

[0088] The above combination can also be removed from the wheel axle 4. The connection of the wheel hub parts can be released, so that the tire 1 can be released from the wheel hub parts. In this way, a worn tire can be removed and replaced by a new tire.

[0089] During the receiving by the wheel hub parts, the tire 1 is not deformed or only slightly deformed, in addition to possible clamping. This allows the receiving of a tire 1 with a high rigidity, such as is common on roller skates, inline skates, scooters and similar products.

[0090] The first tire clamping surface 13 and the second tire clamping surface 14 can be designed mirror-symmetrically with respect to a mirror plane 16, which is oriented at a right angle to the wheel axle 4.

[0091] In a preferred case, the wheel hub part also comprises a further locking element 29, which prevents a rotation of the first wheel hub part 2 relative to the second wheel hub part 3. The connection of the wheel hub parts is ensured by the further locking element 29.

[0092] With regard to Figure 3 :

[0093] Figure 3 An exploded view of a further embodiment of a wheel hub and tire 1 combination according to the present application is shown. In addition to the features of the embodiment shown in Figure 1 and Figure 2 described above, the embodiment shown in Figure 3In the embodiment shown, the tire 1 comprises at least one tire recess 17 and at least one hub part comprises a tire connection protrusion 18, which engages with the tire recess 17. In addition to the above-mentioned means, the tire 1 can also be secured by means of the tire recess 17 and the tire connection protrusion 18. Figure 3 The embodiment shown comprises a plurality of tire recesses 17 arranged radially on the tire 1 and a plurality of tire connection protrusions 18 arranged radially on the hub part, in the preferred case.

[0094] With regard to Figure 4 :

[0095] Figure 4 A sectional view of the embodiment shown is shown. Figure 3 A sectional view of the embodiment shown is shown.

[0096] With regard to Figure 5 :

[0097] Figure 5 An exploded view of a first embodiment of the application is shown. Figure 5 A hub with a tire 1, a first hub part 2 and a second hub part 3 is shown. The hub parts comprise a first opening 5 or a second opening 6 for rotatably mounting the hub parts about a wheel axis 4. The wheel axis 4 is only symbolically represented in the form of a dashed line in Figure 5 .

[0098] The hub parts are arranged at a variable hub distance 7 from one another in the case of a single wheel axis 4. The hub distance 7 can be changed by assembling the hub parts into a hub.

[0099] The hub comprises an LED element 19 arranged between the first hub part 2 and the second hub part 3 and secured thereby.

[0100] Figure 5 A special case is shown, in which the first hub part 2 and the second hub part 3 comprise a first recess 20 or a second recess 21 for detachably mounting the LED element 19. It is also conceivable that only one of the hub parts comprises such a first recess 20 or a second recess 21 or a similar protrusion for detachably mounting the LED element 19. In the preferred case, the first recess 20 or the second recess 21 or a similar protrusion has a shape that matches the LED element 19, so that the LED element 19 can be secured by form closure. Clamping securing with or without the first recess 20 or the second recess 21 or the protrusion is also conceivable, as long as the LED element is not subjected to excessive loads due to the clamping force.

[0101] As a supplement or alternative to the form fit, the skilled person is also familiar with other adhesive or mechanical connection methods for detachably arranging the LED element 19 on or in the first hub part 2 and / or the second hub part 3.

[0102] The LED element 19 comprises a generator 22, wherein one part of the generator 22 is fixed by the hub parts and another part of the generator 22 is fixed by the axle 4. By the relative movement between one of the hub parts and the axle 4, the parts of the generator 22 are also moved and generate an electric current when the hub is rotated. It is also conceivable to replace the generator as an electric power source by a rechargeable battery (Akku), wherein the electric power output of the rechargeable battery is connected to the LEDs 23, if applicable.

[0103] The LED element 19 further comprises LEDs 23 which are arranged in a radial direction. When supplied with electric power, the LEDs 23 emit light through the tire 1. In the assembled state of the hub, the hub parts and the LED element 19 are arranged inside the tire 1. Both the tire 1 and the hub parts protect the LED element 19. In the assembled state of the hub, the LEDs 23 are arranged in the tire 1. Figure 5 In the shown embodiment, the hub parts are preferably connected to each other by mechanical connection means and / or adhesive connection agents. The hub is formed by assembling the hub parts together in the assembly direction 15.

[0104] In addition, as shown in Figure 5 The hub parts further comprise a further locking element 29 which prevents a rotation of the first hub part relative to the second hub part. By the further locking element 29, a connection of the hub parts is ensured. In combination with Figure 5 In combination with the shown embodiment, according to one embodiment of the hub of the present application, the further locking element 29 comprises a cover and three locking bars which are arranged on the cover and which extend in parallel to the axle 4, wherein the three locking bars are arranged in a triangle, i.e. two of the three locking bars are arranged at an upper position of the cover and the third of the three locking bars is arranged at a middle or lower position of the cover and in between the two locking bars. See Figure 5As shown, the length of the two locking rods located at the upper part of the cover body is greater than that of the third locking rod located at the middle or lower part of the cover body, three first locking rod recesses are arranged on the first hub component 2, and the three first locking rod recesses correspond to the three locking rods respectively, two second locking rod recesses are arranged on the second hub component 3, and the two second locking rod recesses correspond to the two locking rods located at the upper part of the cover body respectively, the end of the three locking rods away from the cover body is provided with a hook body, the hook body of the two locking rods located at the upper part of the cover body can hook the limiting block in the second locking rod recess, and the hook body of the third locking rod can hook the limiting block in the corresponding first locking rod recess. In this way, by respectively passing the two locking rods located at the upper part of the cover body through the first locking rod recess and the second locking rod recess and hooking the hook bodies of the two locking rods to the corresponding limiting blocks respectively, and by passing the third locking rod through the corresponding first locking rod recess and hooking the hook body of the locking rod to the corresponding limiting block, the installation of another locking element 29 is realized, and the another locking element 29 can prevent the first hub component 2 from rotating relative to the second hub component 3, and the connection of the hub components can be ensured through the another locking element 29.

[0105] Further, with reference to Figure 5 As shown, the LED element 19 further comprises radially arranged LEDs 23, and the above-mentioned two second locking rod recesses are located on the two sides of one of the LEDs 23, that is, after the installation of the another locking element 29, the two locking rods located at the upper part of the cover body clamp the LED 23, and the another locking element 29 can further ensure that the first hub component 2 cannot rotate relative to the second hub component 3. In the extension direction of the wheel shaft 4, the projection of the LED 23 can overlap the first locking rod recess corresponding to the third locking rod.

[0106] With regard to Figure 6 :
