[0001] Description

[0002] rim

[0003] The invention relates to a rim according to the preamble of claim 1.

[0004] The invention disclosed here relates to a rim with a tire, which rim comprises a first rim part and a second rim part. When viewed perpendicular to the rim, the rim parts have a cross-section suitable for a circular tire, usually also circular. The first rim part comprises a concentrically arranged first opening. The second rim part comprises a concentrically arranged second opening. The openings serve to rotatably mount the rim parts about a wheel axle.

[0005] The rim parts can be joined together such that a single wheel axle extends through the first opening and through the second opening. The rim parts can be arranged at a rim distance greater than or equal to zero, measured in the direction of the wheel axis.

[0006] The rim parts can be moved relative to each other along the wheel axis, provided that the relative movement to each other is not blocked by a locking element described below.

[0007] DE7834277U1 discloses a two-piece rim with a bayonet lock. This bayonet lock is arranged in a plane of the rim parallel to the tread. This arrangement is disadvantageous for the user because the user cannot check the proper connection via the closed bayonet lock.

[0008] US2219156 does not disclose a projection with a locking element arranged between the free and closed ends of the projection (see, among others, Figure 4 of US2219156). Furthermore, in US2219156, the locking element 14 of the first rim part is arranged on the applied side of the second rim part and not in a locking element recess of a spoke of the second rim part by relative rotation of the rim parts. US20100107946 does not disclose projections with locking elements, which locking elements are each arranged between the connected end and the free end of the projection.

[0009] In DE20118566, Figure 2 shows that the projections 332, 331 of one rim part 31 and the projections 341, 342 of the rim ring 32 are arranged in the tire. All projections are arranged in the rim rims 314, 322 and thus cannot be inserted into recesses formed by the spokes.

[0010] US20170274989 does not disclose a projection with a locking element arranged between the free and closed ends of the projection (see, among others, Figure 4 of US20170274989). In US20170274989, it is not arranged in a locking element recess of a spoke of the second rim part by relative rotation of the rim parts.

[0011] US1541445 , Figure 2 shows a projection and a locking element which are arranged in the rim and thus not in the spoke area.

[0012] The invention disclosed here has the first task of making the rim parts interchangeable.

[0013] According to the invention, this first object is achieved by claim 1.

[0014] The first rim part comprises, in a first spoke region, at least one projection extending in the direction of the wheel axis, which projection can be introduced into a projection recess in the second rim part, wherein the projection comprises a locking element at the free end or between the free end and the connected end of the projection, which locking element can be brought into engagement with the second rim part.

[0015] The projection is arranged in the spoke area and / or in the rim flange and / or rim flank of the first rim part. Accordingly, the projection recess is arranged in the spoke area or in the rim flange or in the rim flank of the second rim part, so that the projection can be inserted into the projection recess. This feature is illustrated in the figures.

[0016] Possible embodiments of the rim according to the invention are shown below, explaining how the locking element can be brought into engagement with the second rim part.

[0017] The solution according to the invention is characterized in that the locking element can be introduced into a locking element recess arranged in a spoke of the second rim part.

[0018] The locking element comprises a locking element partial surface which is oriented at a right angle to the wheel axis. The locking element recess comprises a locking element recess partial surface which is oriented at a right angle to the wheel axis. When an engagement is established, the aforementioned partial surfaces make contact and, as contact surfaces, prevent the rim parts from moving relative to one another, in particular from moving apart. Different angles to the aforementioned angles are also conceivable, provided that movement of the rim parts relative to one another is prevented.

[0019] The spoke area, particularly the outer spoke area, is visible to the user. The user can check whether the connection established by the locking element engaging with the second rim part has been released.

[0020] The locking element recess can have a shape adapted to the shape of the engaged locking element, so that when properly engaged, the locking element fills the locking element recess. Congruent shapes of the locking element recess and the inserted locking element are conceivable. The locking element can have a variable shape, so that when the locking element is inserted into the locking element recess, the locking element assumes a shape congruent with the locking element recess. The locking element can also have a fixed shape.

[0021] In this way, a displacement of the locking element or the beginning of a loosening of the engagement is easily recognizable by a person skilled in the art. Possible shapes of the locking element recess are discussed below based on the embodiments illustrated in the figures.

[0022] The locking element can be held by a clamp. According to the prior art, clamping can be achieved by elastically deforming at least one contact surface of the locking element or of the locking element recess. A clamping engagement of the locking element with the second rim part can also be produced in such a way that, when the aforementioned engagement is produced, at least one rim part is deformed in the direction of the other rim part. The aforementioned deformation of a rim part can be produced, for example, by curving the first rim part towards the second rim part or vice versa, or by curving the rim parts towards one another. A clamping engagement can also be produced by stretching the projection. The forms of clamping engagement mentioned as examples have the common property that the rim parts are pressed towards one another.

[0023] The locking element can be held in the locking element recess via a locking connection. A contact surface of the locking element and a contact surface of the locking element recess can each comprise a partial element of the locking connection.

[0024] The locking element can be secured by another mechanical connection such as a screw in the locking element recess.

[0025] The projection connected to the first rim part comprises a free end and a connected end, at which connected end the projection is connected to the rim part. The locking element can be designed as a projection at the free end or as a projection arranged between the free end and the connected end.

[0026] As an alternative or in addition to the detachable connection of the rim parts mentioned as an example, the user can make the connection non-detachable, for example by gluing the locking element to the second rim part. The locking element can be secured against opening by an additional mechanical connecting means or by an adhesive connection. The rim according to the invention can be characterized in that the projection extends radially or tangentially to the first wheel axis.

[0027] The projection may be in the shape of a cuboid. The cuboid may protrude from a spoke surface defined by the spokes and extend in a radial or tangential and longitudinal direction to the wheel axis.

[0028] The projection may extend from the rim flank or from the rim flange in a radial or tangential direction and in a longitudinal direction to the first wheel axis.

[0029] The projection is oriented so as to project towards the second rim part in order to be introduced into a projection recess arranged in the second rim part.

[0030] The projection can be held in the projection recess by clamping or by a locking connection or by another mechanical connection in the projection recess.

[0031] The locking element can be a separate element from the projection. The locking element can be formed integrally with the projection. Advantageously, the first rim part, together with the projection and the locking element, is made from a single plastic part.

[0032] The rim according to the invention is characterized in that the locking element arranged at the free end of the projection or between the free end and the connected end of the projection can be brought into engagement with the second rim element by rotating the first rim element about the wheel axis and relative to the second rim element, the locking element being introduced into the locking element recess. For this purpose, the locking element is designed as a projection element oriented in the direction of rotation and thus in the radial direction, further to the recess. The above-mentioned contact surfaces A possible embodiment of the design of the projection and the locking element as well as the recess is discussed in the following description of the figures.

[0033] The rim according to the invention, in particular the second rim part, can be characterized in that the projection can be introduced into a projection recess of the second rim part defined by one spoke or by two spokes.

[0034] The projection recess may be formed in a spoke. The hollow space between two spokes may be considered a projection recess.

[0035] The rim according to the invention is characterized in that the locking element can be introduced into a locking element recess arranged in a spoke of the second rim part or into a locking element recess of a rim cover placed on the second rim part.

[0036] The invention disclosed here also addresses the second problem of being able to replace a tire made of solid rubber. According to the prior art, tires made of solid rubber for kickboards and similar vehicles have very low elasticity and for this reason cannot be slipped onto a rim. A tire according to the prior art is sprayed or poured onto existing one-piece rims. A worn-out or no longer usable tire means that the inseparable combination of rim and wheel rim manufactured according to the prior art has to be disposed of. In particular, recycling is not possible because a combination of wheel and rim comprises several materials.

[0037] By inserting the locking element into the locking element recess, the rim parts can be pressed against each other, thereby compressing a tire held between the rim parts. By inserting the locking element into the locking element recess, an increasing preload force can be generated while deforming the tire, with which preload force the rim parts are pressed against each other.

[0038] The invention disclosed here has the object of making it possible to remove a tire from the rim so that only the worn tire can be replaced by a new tire.

[0039] The rim according to the invention can be characterized in that the rim parts comprise a first tire clamping surface and a second tire clamping surface, wherein the tire is held or clamped by the tire clamping surfaces. As explained at the beginning, the rim according to the invention comprises at least two rim parts, which rim parts are connected by a detachable connection. An intermediate element can be arranged between the rim parts. The connected rim parts hold the tire in a form-fitting and / or clamping manner. By releasing the connection holding the rim parts and after moving the rim parts apart, the worn tire can be replaced with a new tire. The rim according to the invention can then be reassembled.

[0040] The rim according to the invention can be characterized in that the tire clamping surfaces are formed so as to be mirror-symmetrical to a mirror axis, which mirror axis is oriented at a right angle to the wheel axis.

[0041] The rim according to the invention can be characterized in that a further locking element prevents rotation of the first rim element relative to the second rim element.

[0042] The rim according to the invention can be characterized in that the tire comprises at least one tire recess and at least one rim part comprises at least one tire receiving projection, which tire receiving projection is brought into engagement with the tire recess.

[0043] The tire recess and the tire receiving projection serve to further accommodate the tire by at least one rim part. The tire recess can be formed as radially extending recesses in the tire wall, into which tire recesses and radially formed tire receiving projections are inserted. Advantageously, the tire comprises at least one tire recess on both sides contacting the rim parts, and tire receiving projections that match the rim parts.

[0044] The invention further relates to the arrangement of a light source such as an LED in or on the rim.

[0045] State-of-the-art rims with an LED light source are enjoying increasing popularity, particularly for children's rides like scooters, kickboards, etc. The light source can be switched on when a rim rotates and off when the rim is stationary, indicating the rim's rotation to the child.

[0046] According to the current state of the art, rims are formed as a single piece, at least with the light source. It is not possible to separate a defective light source from the rim, for example.

[0047] The invention disclosed here addresses the problem of removably arranging an LED in or on the rim. This problem can also be solved independently of the mechanical connection of the rim parts described above by the following invention.

[0048] The first solution provides that at least one rim part includes an LED element.

[0049] A rim part can be designed as an LED element.

[0050] The second solution provides that an LED element is arranged between the first rim part and the second rim part.

[0051] The LED element is held directly or indirectly by the rim parts. With indirect support of the rim parts, another element, such as a tire, is arranged between the rim part and the LED element.

[0052] At least one rim element can comprise, on its surface facing the LED element, an LED element recess or an LED element projection for detachably mounting the LED element.

[0053] The third solution provides for an LED element to be arranged on the outside of a rim part.

[0054] The rim part can comprise an LED element recess or an LED element projection for detachably mounting the LED element.

[0055] The three approaches mentioned can be characterized by the fact that the LED element is arranged within a tire held by the rim parts. This has the advantage that the LED is protected by the tire. An LED element is mentioned here as an example of a lighting source because the use of an LED element is advantageous compared to other electrical lighting sources. However, the invention in no way excludes the use of other electrical lighting sources such as light bulbs, etc.

[0056] The LED element can be connected to at least one rim part directly or indirectly, and thus via another element. The connection can be detachable or non-detachable, depending on the proposed solution. The connection can be made using a mechanical fastener or an adhesive fastener. A non-detachable connection between at least one rim part and the LED element can, for example, be such that the LED element and the rim part are formed as a single piece. A single-piece design of the LED element and the rim part can, for example, be produced such that the LED element and the rim part are produced as a single injection-molded element.

[0057] An LED element comprises an LED as the light source and a generator or a battery as the power source. The conduction of current from the battery to the LED can be controlled, in particular, by the movement of a wheel rim part. A generator can, for example, be operated by the relative movement between the wheel axle and a wheel rim part. A generator can only supply power to the LED when there is a relative movement between the wheel axle and a wheel rim part.

[0058] One LED element or several individual LED elements can be arranged so that light is emitted in a radial direction toward the rim element or the wheel axle. The emitted light can, for example, be transmitted through a tire into the environment.

[0059] A longitudinally emitting LED can emit light directly or indirectly via a rim part to the environment.

[0060] The LED element can comprise a plurality of LEDs arranged on a strip. The strip can extend at a distance from the at least one rim part or the wheel axle. The rim according to the invention can be characterized in that at least one rim part or another element is made of a translucent material, which further part is arranged in the rim.

[0061] A portion of the light emitted by the LED can be transmitted to the surrounding area via a portion of the rim. Partial amounts of the light can be transmitted via different portions. According to current theory, this allows the light to be used to display a pattern on the rim.

[0062] A translucent element with light-focusing or light-scattering properties, such as a crystal or a lens, can be arranged in the rim to emit the light within the rim or to the environment.

[0063] The rim can be designed according to the features of the dependent claims. The invention is further explained with reference to the following embodiments shown in the figures:

[0107] Regarding Figures 1 and 2:

[0108] Figure 1 shows a rim with a tire 1. The rim comprises a first rim part 2 and a second rim part 3.

[0109] Figure 2 shows a view of the second rim part 3 .

[0110] The first rim part 2 has a circular first surface extension, which surface extension is oriented at an angle of 90 degrees to the one wheel axle 4. The second rim part 3 has, as it were, a circular second surface extension, which second surface extension is oriented at an angle of 90 degrees to the wheel axle 4. The wheel axle 4 extends through a first opening 5 arranged in the center of the first rim part 2 and a second opening 6 arranged in the center of the second rim part 3. The first rim part 2 is rotatably mounted on the wheel axle 4 through the first opening 5 and the second rim part 3 is rotatably mounted through the second opening 6.

[0111] The first rim part 2 and the second rim part 3 can be arranged at a rim spacing 7. The rim spacing 7 can be varied—when the rim parts 2, 3 are not connected vertically—by possibly shifting the rim parts 2, 3 relative to one another. The rim spacing 7 is shown symbolically in Figure 1. The rim spacing 7 can be zero when the rim parts 2, 3 are joined together.

[0112] The first rim part 2 comprises at least one projection 8 extending in the direction of the wheel axle 4. The projection 8 is arranged on the side of the first rim part 2 facing the second rim part 3. The projection 8 is designed as a cuboid extending at a right angle to the first surface extension. Other shapes of the projection 8 are also conceivable.

[0113] The second rim part 3 comprises a projection recess 9 in the second surface extension. The projection recess 9 is designed such that the projection 8 can be inserted into the projection recess 9.

[0114] The embodiment shown in Figure 1 advantageously comprises a plurality of projections 8 and a plurality of projection recesses 9. In order to maintain clarity of the figures, only a selection of the projections 8 and the projection recesses 9 are identified by a reference symbol.

[0115] A locking element 11 is arranged between the free end 10 and the connected end of the projection 8. The locking element comprises a contact surface, which contact surface is oriented at a right angle to the wheel axis 4.

[0116] The embodiment shown in Figure 1 is designed such that the locking element 11 is brought into engagement with the second rim part 3 on the side of the second rim element 3 which is arranged towards the first rim element 2. In the embodiment shown in Figure 1, the locking element 11 is arranged by introducing the projection 8 into the projection recess 9 on the side of the second rim part 3 which is facing away from the first rim part 2. By rotating the first rim part 2 about the wheel axis 4 (here for example clockwise) and relative to the second rim part 3, the locking element 11 can be brought into engagement with the second rim part 3. The locking element 11 thus positioned extends parallel to the side of the second rim part 3 facing away from the first rim part 2 and thus establishes a connection between the first rim part 2 and the second rim part 3.This connection prevents movement of the rim parts 2, 3 relative to each other and in the direction of the wheel axis 4. Figure 3 shows an engaged position of the first rim part 2 and the second rim part.

[0117] The embodiment illustrated in Figure 1 advantageously comprises a plurality of projections 8. Each projection 8 is arranged to project from the side of the first rim part 2 facing the second rim part 3. The projections 8 are arranged radially around the wheel axis 4 on the side of the first rim part 3 facing the second rim part 3.

[0118] Each projection 8 of the first rim part 2 is assigned a matching projection recess 9 in the second rim part 3. Due to the advantageous design of the projections 8 and the projection recesses 9 with identical cross-sections, as shown here, each projection 8 can be inserted into each projection recess 9.

[0119] The projection recess 9 can be formed as such in a second rim part 3 designed as a disc or in a spoke of the second rim part 3. Figure 1 shows an embodiment with an attractive design, in which embodiment the projection recess 9 is formed as a recess defined by two adjacent spokes.

[0120] It is mentioned above that the locking element 11 is positioned on a side of the second rim part 3 facing away from the first rim part 2. This side, with which the locking element 11 is brought into engagement with a locking element surface, is specifically designed as a locking element recess 12 in a spoke of the second rim part 3.

[0121] The above description of the figures relates to the first task of the invention.

[0122] To achieve the second objective, the rim parts 2, 3 comprise a first tire clamping surface 13 and a second tire clamping surface 14. The tire 1 is held by the tire clamping surfaces 13, 14 or held in a clamped manner after a pre-tensioning force is applied. The tire 1 is received by the rim parts 2, 3 by bringing the rim parts 2, 3 together (see arrows 15) and connecting the rim parts 2, 3 by the locking element 11. The tire 1 and the rim parts 2, 3 are thereby mounted so as to be rotatable relative to the wheel axle 4 and about the wheel axle 4. For this purpose, the combination of rim parts 2, 3 and tire 1 can be pushed onto the wheel axle 4.

[0123] The aforementioned combination can also be removed from the wheel axle 4. The connection between the rim parts 2, 3 can be loosened, thus releasing the tire 1 from the rim parts 2, 3. In this way, a worn tire can be removed and replaced with a new one.

[0124] The tire 1 is not deformed or only slightly deformed during the manufacture of the mount by the rim parts—apart from any clamping. This allows the mounting of a tire 1 with a high degree of rigidity, which is common, for example, in scooters, inline skates, kickboards, and the like.

[0125] The tire clamping surfaces 13, 14 can be designed to be mirror-symmetrical to a mirror axis 16 or mirror surface, which mirror axis 16 is oriented at a right angle to the wheel axis 4.

[0126] Regarding Figure 3:

[0127] The rim parts 2, 3 can advantageously have a further locking element 19 (not shown in Figure 1, see Figure 3), which further locking element 19 prevents rotation of the first rim element relative to the second rim element. The connection of the rim parts 2, 3 is secured by the further locking element 19.

[0128] Figure 3 shows an exploded view of a further embodiment of the combination of rim and tire 1 according to the invention. In addition to the features of the embodiment shown in Figures 1 and 2 and described above, in the embodiment shown in Figure 3 the tire 1 comprises at least one tire recess 17 and at least one rim part 2, 3 comprises a tire receiving projection 18, which tire receiving projection 18 is brought into engagement with the tire recess 17. The tire 1 is held by the tire recess 17 and the tire receiving projection 18 in addition to the means described above. The embodiment shown in Figure 3 advantageously comprises a plurality of tire recesses 17 arranged radially on the tire 1 and tire receiving projections 18 arranged radially on the rim parts 2, 3.

[0129] Figure 3 shows the further locking element 19, which is already mentioned in the description of Figure 1.

[0130] Regarding Figure 4:

[0131] Figure 4 shows a sectional view of the embodiment shown in Figure 1 or Figure 3.

[0132] In Figure 4, the locking element recess 12 for receiving the locking element 11 is visible on the side of the second rim part 3, which side of the second rim part 3 faces away from the first rim part 2.

[0133] The locking element recess 12 has a shape which is open to the outside and thus to the side facing away from the first rim part. The locking element recess 12 can also have an alternative shape which is closed to the outside and has only a recess for receiving the locking element 11, as shown in Figure 10.

[0134] Regarding Figure 5:

[0135] Figure 5 shows an exploded view of a first embodiment of the invention. Figure 5 shows a rim with a tire 1, a first rim part 2, and a second rim part 3. The rim parts 2, 3 comprise a first opening 5 and a second opening 6, respectively, for rotatably supporting the rim parts 2, 3 about a wheel axle 4. The wheel axle 4 is shown only symbolically in Figure 5 in the form of a dash-dotted line.

[0136] The rim parts 2, 3 are arranged at a variable rim distance 7 to form a single wheel axle 4. The rim distance 7 can be changed by assembling the rim parts 2, 3 to form a rim.

[0137] The rim comprises an LED element 19 which is arranged between the first rim part 2 and the second rim part 3 and is held thereby.

[0138] Figure 5 shows the special case in which the first rim part 2 and the second rim part 3 comprise a first LED element recess 20 and a second LED element recess 21, respectively, for the detachable mounting of the LED element 19. It is also conceivable for only one rim part 2, 3 to comprise such an LED element recess 20, 21 or, equivalently, a projection for the detachable mounting of the LED element 19. The LED element recesses 19, 20 or, equivalently, the projections advantageously have a shape adapted to the LED element 19, so that the LED element 19 is held by a positive fit. A clamping holder is also conceivable, with or without LED element recesses 20, 21 or projections, provided that the clamping force does not place excessive strain on the LED element.

[0139] In addition to or as an alternative to the positive connection, the person skilled in the art also knows further adhesive or mechanical connection methods for the detachable arrangement of the LED element 19 on or in the first rim part 2 and / or second rim part 3.

[0140] The LED element 19 comprises a generator 22, wherein one part of the generator 22 is held by a rim part 2, 3 and another part of the generator 22 is held by the axle 4. A relative movement between a rim part 2, 3 and the axle also moves the parts of the generator 22, and current is generated when the rim rotates. Instead of the generator, a rechargeable battery is also conceivable as a power source, wherein the current output from the rechargeable battery is preferably connected to an LED 23.

[0141] The LED element 19 further comprises LEDs 23 arranged in the radial direction. The LEDs 23 emit light through the translucent tire 1 when supplied with current. In the assembled state of the rim, the rim parts 2, 3 and the LED element 19 are arranged inside the tire 1. The tire 1 and also the rim parts 2, 3 protect the LED element 19. In the embodiment shown in Figure 5, the rim parts 2, 3 can be connected to one another in an advantageous manner by a mechanical connecting means 8, 9 and / or by an adhesive connecting means. The rim is formed by bringing the rim parts 2, 3 together 15.

[0142] Figure 5 further shows the further locking element 29. The further locking element 29 comprises at least one insertion part 30, which insertion part 30 is inserted into a cavity formed by two spokes of the rim parts 2, 3. In Figure 5, the further locking element 29, in particular the insertion parts 30, is inserted via the cavity between two spokes of the first rim part 2 into the cavity between two spokes of the second rim part 3. The further locking element is held on the first rim part 2 by a plate connecting the insertion parts 30 and on the second rim part 3 by a snap-in connection.

[0143] Regarding Figure 6:

[0144] Figure 6 shows a sectional view of another embodiment of the rim according to the invention. The rim again comprises assemblable rim parts 2, 3, which rim parts 2, 3 form a common wheel axle 4. The wheel axle 4 is again shown as a dot-dash line.

[0145] An LED element 19 is arranged close to the wheel axle 4. The LED element 19 can in turn comprise a generator 22, wherein a part of the generator 22 connected to the wheel axle 4 and another part of the generator 22 connected to a rim part 2, 3 are moved relative to one another by the rotational movement of a rim part 2, 3 to the wheel axle 4. The LED is designed as an LED strip 24 which runs around the wheel axle 4 at a distance, which LED strip 24 emits the light to the environment via a light-permeable spoke region 28.

[0146] The rim parts 2, 3 are advantageously formed in the spoke area 28 from a glass or other translucent material.

[0147] Regarding Figure 7:

[0148] Figure 7 shows an exploded view of the LED element 19 from Figure 6 .

[0149] The LED element 19 comprises a generator 22. The generator 22 comprises two parts, which are moved relative to each other to generate current. Such generators are known in the art.

[0150] The LED element 19 further comprises an LED strip 24, which LED strip 24 is arranged at a distance from the wheel axle 4. The LED strip 24 contacts and preferably runs around the outer part of the generator 22 in the sense of a compact design. The LED strip 24 here comprises at least one radially arranged LED (not shown in Figure 7), which LED emits a light via the spoke region 28 of a rim part 2, 3, which spoke region is made of a translucent material. Figure 7 shows the special case in which the translucent spoke region 28 is designed as a component separate from the rim parts 2, 3.

[0151] The translucent spoke area 28 can be mounted immovably via a mechanical connection to the rim parts 2, 3.

[0152] The LED element 19 is arranged between the rim parts 2, 3, 28, as shown in Figure 6. The rim parts 2, 3, 28 hold the LED element 19 via a positive fit.

[0153] Figures 6 and 7 show an arrangement of the LED strip 24 near the wheel axle 4. It is also conceivable that the LED strip is arranged near the tire 1, so that the light is emitted via a translucent tire 1 and / or via the spoke area. Regarding Figure 8:

[0154] Figure 8 shows an exploded view of another embodiment of the rim according to the invention, which embodiment is similar to the embodiment shown in Figure 5. The rim comprises substantially similar elements to the embodiment according to Figure 5.

[0155] In contrast to the embodiment according to Figure 5, the first rim part 2 comprises the LED element 19. The LED element 19 can be formed integrally with the first rim part 2. The LED element 19 and the first rim part 2 can be manufactured as a molded part, such as an injection-molded part. The LED element 19 can also be inseparably connected to the first rim part 2 by an adhesive layer or by a mechanical connection.

[0156] Regarding Figure 9:

[0157] Figure 9 shows an exploded view of another embodiment of the rim according to the invention.

[0158] Figure 9 shows a rim with a tire 1 comprising a first rim part 2 and a second rim part 3, which rim parts 2, 3 comprise a first opening 5 and a second opening 6 respectively for rotatable mounting about a wheel axle 4. The rim parts 2, 3 can be arranged at a variable rim distance 7 to form a single wheel axle 4. An LED element 19 is arranged outside the second rim part 3. Figure 9 shows a detachable arrangement of the LED element 19 on the second rim part 3, which detachable arrangement is produced by a mechanical connection or an adhesive connection between the LED element 19 and the second rim part 3. A non-detachable connection is also conceivable here.

[0159] The rim further comprises a decorative cover 27 with preferably translucent properties. Thus, light emitted by the LED 23 can be emitted via the decorative cover 27.

[0160] In the embodiments described here, the tire 1 preferably has translucent properties, so that light emitted by the LED 23 is emitted via the tire. The figure description for Figure 9 includes a detailed description of the LED element 19, which detailed description also applies to the other figure descriptions.

[0161] The figures described above show only one possible mechanical connection form for the rims that can be assembled, which connection form comprises a projection 8 and a recess 9. Other mechanical or adhesive connection forms for connecting the rim parts 2, 3 are also conceivable, and these connection forms can be used by a person skilled in the art. The figures described above also show one possible connection form for the tire 1 to the rim parts 2, 3. Other connection forms are also conceivable here.

[0162] Figure 10 :

[0163] Figure 10 is described with reference to Figure 4. The embodiment shown in Figure 10 differs from the embodiment shown in Figure 4 only in the shape of the locking element recess 12.
