  Abnehmbare Felge. 



   Die Erfindung betrifft eine abnehmbare Felge und besteht insbesondere darin, dass zwischen einer Schlossplatte und einer Deckplatte die Enden der geteilten Grundfelge durch Drehen einer Doppelnocke zusammengezogen oder auseinandergeschoben werden können.

   Die Felge 8 des Drahtspeichenrades (Fig. 1) ist geteilt und wird durch ein Schloss (Fig. 2,3 und 4) zusammengehalten. Dieses Schloss ermöglicht die Grundfelge   8     periphe1Îsëh   zusammenzuziehen oder bei aufgelegter Pneumatikfelge 15 auseinander zu schieben. Zu diesem Zwecke

   Die Grundfelge ist an der Peripherie derart geformt, dass sie in auseinandergeschobenem Zustande mit ihrer Krempe (Fig. 2 und 4) die Hilfsfelge   umfasst   und dadurch ein axiales Ver-

  Die Flügelmuttern tragen an ihren   zylindrischen   Teilen Verstärkungen   12,   um das Herausfallen derselben in   angeschraubtem   Zustande zu verhindern. Die abnchmbare Pneumatikfelge 15 ist derart geteilt, dass ihre Enden (Fig. 6)   ineinandergreifen, sodnss ein axiales Verschieben   derselben unmöglich ist. Die Teilungsfuge ist durch eine Stahlplatte 16, welche an einem Ende der Hilfsfelge aufgenietet ist gedeckt, wodurch das Einzwicken des   Pneumatikschlauches verhindert   wird. An der Stahlplatte 16 sind zwei Einbeulungen 22 angebracht, welche die   Bohrungen 8     (Fig. 3, 5.   6,7) des Felgenringes überdecken.

   Die Bohrungen   23 diesen   zur Aufnahme einer Vorrichtung, mit welcher ermöglicht wird, die Hilfsfelge zusammenzuziehen, sodass der Durchmesser soweit verkleinert wird, dass der Pneumatik leicht aufgelegt   werden kann (Fig. 7). Ist   der Pneumatik aufgelegt, so wird die Felge mit derselben   Vorrichtung auseinandergespannt, bis   ihre beiden Enden wieder   zusammenstossen   (Fig. 5 und 6).

Das Plättchen 18 der Pneumatikfelge greift in den konischen Raum der auf der Radfelge aufgenieteten Plättchen 17, wodurch ein gegenseitiges Verschieben der beiden Felgen unmöglich ist.

  Removable rim.



   The invention relates to a removable rim and consists in particular in that the ends of the divided base rim can be drawn together or pushed apart between a lock plate and a cover plate by rotating a double cam.
 EMI1.1
 The floor plan is shown in FIGS. 9 and 10 with the cover plate 3 removed: FIG. 12 shows a longitudinal section of the two rims at the tube valve.



   The rim 8 of the wire spoke wheel (Fig. 1) is divided and is held together by a lock (Fig. 2, 3 and 4). This lock enables the base rim 8 to be drawn together periphe1Îsëh or to slide it apart when the pneumatic rim 15 is in place. For this purpose
 EMI1.2
 Go through the locking plates (Fig. 8, 9, 10 and 11).



   The base rim is shaped on the periphery in such a way that, when pushed apart, it surrounds the auxiliary rim with its rim (Figs. 2 and 4), thereby creating an axial
 EMI1.3
 



  The wing nuts have reinforcements 12 on their cylindrical parts in order to prevent them from falling out in the screwed-on state. The detachable pneumatic rim 15 is divided in such a way that its ends (FIG. 6) interlock, so that an axial displacement of the same is impossible. The dividing joint is covered by a steel plate 16, which is riveted to one end of the auxiliary rim, which prevents the pneumatic hose from being pinched. On the steel plate 16 there are two indentations 22 which cover the bores 8 (Fig. 3, 5, 6,7) of the rim ring.

   The bores 23 these for receiving a device with which it is possible to draw the auxiliary rim together so that the diameter is reduced to such an extent that the pneumatic system can easily be placed on (FIG. 7). Once the pneumatic system has been applied, the rim is stretched apart with the same device until its two ends meet again (FIGS. 5 and 6).



     So that the wing nuts 11 of the wheel rim pushed apart come to stand concentrically with the screw bolts 10 of the rim 15, on the one hand on the wheel rim and

The plate 18 of the pneumatic rim engages in the conical space of the plate 17 riveted onto the wheel rim, whereby mutual displacement of the two rims is impossible.



    PATENT. AN8PROCBE.



     1. Removable rim, characterized in that between the lock plate (2) and the cover plate (3) the ends of the divided base rim (8) are pulled together or pushed apart by rotating a double cam (1).

Claims

2. Rim according to claim 1, characterized in that the cutouts (20) for the double. cams are shaped in such a way that when the cam is rotated slightly more than 9 () 0, an automatic turning back is prevented when the rim ends (8) are pushed apart.

3. Rim according to claim 1 and 2, characterized in that the lock plate (2) with the cover plate (3) by bolts (5) and screws (6) is connected, a space is created between the two plates in which the ends of the Rim (8) are guided by means of the slots (7).

4. Rim according to claim 1 to 3, characterized in that the lock plate (2) has edges (24) which cause the two ends of the rim (8) to be held together axially.

5. Rim according to claim 1 to 4, characterized in that the base rim (8) is provided on both sides of the closure with bores (13) in which the wing nuts (11) are mounted. EMI2.1 their cylindrical part are provided with a reinforcement (12), which prevents falling out of the bore (13).

7. A rim according to claim 1 to 6, characterized in that the removable rim (15) is divided in such a way that the ends engage in one another and thus an axial displacement is prevented. EMI2.2 is attached, is covered and thus prevents the pneumatic hose from being entangled.

9. A rim according to claim 1 to 8, characterized in that the cover plate (16) has bulges (22) which cover the bores (23) of the rim (15) in such a way that a hollow space is created between the rim and the cover plate.

10. A rim according to claim 1 to 9, characterized in that the detachably split rim is provided on both sides of its dividing joint with dents (9) and screw bolts (10) onto which the wing nuts (11) are screwed, whereby the two rims are firmly held together achieved and mutual displacement of the same is prevented.

11. A rim according to claim 1 to 10, characterized in that the removable, split rim is provided with two bores (23) into which the clamping device engages for contracting or pushing the pneumatic rim apart.

12. Rim according to claim 1 to 11, characterized in that on the base rim both- EMI2.3
