Pivoting lever lock for a vehicle, in particular a two-wheel vehicle, with a pivoting lever (20 ; 120) which is pivotably mounted about a pivoting axis (18) on a frame part (12a ; 112a) on the side next to a wheel (10) provided with an opening, i.e., between a locked position where it penetrates the opening and is locked so as to be unable to pivot, if necessary by means of cooperation with a lock bearing (17 ; 117) mounted on an opposite frame part (12b) and a travel position where it is disengaged from the wheel (10) and is secured so as to be unable to pivot, the pivoting lever or an extension (56) of the pivoting lever (20 ; 120) arranged on the pivoting axis side being rotatably mounted in a pivoting boss (16 ; 116) about an axis of rotation (22) perpendicular to the pivoting axis (18) and the pivoting boss (16 ; 116) being pivotably mounted about the pivoting axis (18) on a pivot bearing (14 ; 114) which is to be secured to the frame (12) and which is designed so as to have a pivot bearing pate (14a ; 114a) lying transverse to the pivoting axis (18), and securing against pivoting being ensured at least in the travel position by means of engagement of a securing member (72 ; 172) provided in the region of the boss in a recess (66 ; 166) in the pivot bearing (14 ; 114) for receiving the securing member, it being possible for this engagement to be established or released by rotating the pivoting lever (20 ; 120) or its extension (56) about its longitudinal axis (22) into or out of a rotationally secured position, characterized in that the securing member (72 ; 172) cooperates with an engagement path which is arranged outside the pivoting boss (16 ; 116) on the pivot bearing plate (14a ; 114a), describes a partial circle about the pivoting axis (18) and points in the direction of the pivoting axis (18), this engagement path having or forming the recess (66 ; 166) for receiving the securing member.

Description

DK 151862 C

The present invention relates to a swing bar lock of the kind set forth in the preamble of claim 1.

A lock of the type initially mentioned is known in which a securing element receiving means is arranged on a demand of the swing bearing and where the securing element located on the swing bar is remote from that corresponding to the swing hub. In addition, the pivot bracket is positioned laterally relative to the pivot axis defining the pivot axis.

A similar swing bar lock is known from US Patent No. 4,180,998 in which the swing lock in driving style is not obtained by a recess in the swing bar within the swing hub cooperating with a recess in a swing pin. In this embodiment, the pivot bar with its axis of rotation is also necessarily positioned laterally with respect to the pivot axis, so that an asymmetric design of the pendulum bar latch appears, which can be objected to both from a viewpoint of touch friendliness and a viewpoint of appearance.

For the oscillation protection in this known embodiment, only a relatively small lever arm is available in driving style, which requires a very precise design of the cooperating parts in order to obtain a reliable anti-vibration protection in driving style and possibly also in the blocking path 11 in the case. Finally, there is a danger that due to the recess in the pivot bracket and the recess in the pivot pin there will be a clamp in the pivot bearing especially in intermediate positions.

The object of the invention is to provide a swing bar lock which, from both a touch and an appearance point of view, represents an improvement.

This is achieved according to the invention by the measures specified in the characterizing part of claim 1.

In the design according to the invention, the pivot hub can be designed with at least approximately 2 without structural problems.

DK 151862 C

circular outline about the pivot axis, said circular outline in diameter being equal to the circular outline of the pivot bearing plate. In this way, a mold is obtained which is largely free of corners and edges which can give rise to damage, the shape by its simplicity also being aesthetically satisfactory, which form can be further improved in aesthetically and touch-friendly terms by rotate the bearing plate disposed end surface of the pivot hub as set forth in claim 3, the arc shape extends about the axis of rotation, i. with a generator which is passed along an arc about the axis of rotation.

A further decisive advantage of the swing bar lock according to the invention in relation to the swing bar lock known from said patent is that the engagement of the securing element and the securing element receiving means can be placed at a greater radial distance from the swing axle without an undesirable increase in the design dimensions. available for supporting the swing bar against swinging torques. In particular, the radius of the swing bearing plate can be more or less fully utilized to obtain a larger weight arm. The presence of the sidewall does not significantly affect the aesthetic, appearance or touchability of the swivel lock, as it substantially follows the circumferential surface of the swivel hub. The fuse element receiving means and optionally also the locking element receiving means are arranged parallel to the pivot axis with respect to its direction of action. Similarly, the securing element performs a motion substantially parallel to the pivot axis as it moves between either the pivot release position and the pivot position or between the pivot release position 11 and the pivot lock path 11 in each. This avoids unwanted clamping in the intermediate positions.

The diameter of the swing bearing plate is optimally utilized to support the swing bar in the driving position and possibly also in the locking position.

U.S. Patent No. 3,988,910 discloses a swing bar lock in which the swing bar can be slidably longitudinally 3

DK 151862 C

is carried a locking bolt. Here, the locking bolt engages with its portion projecting from the free swinging bend in the locking position in a locking element receiving member on the overlying frame and in the running for 11 times in a locking element receiving member mounted on an outrigger. However, this support on the swivel bearing must here extend far beyond the dimension of a swivel bearing, which is practically over the entire length of the swivel bracket, so that one cannot in the narrower sense speak of a securing element receiving member in the swivel bearing. In addition, in this known embodiment, the longitudinal axis of the pivot bracket is also set at a considerable distance from the pivot axis, so that a design which is unsatisfactory in terms of aesthetic appearance and touch-friendliness also emerges.

Furthermore, a swing bar lock is known in which the swing bar is pivotally mounted about its longitudinal axis in a swing hub and carries at its free end a locking element which, in locking path 11, does not engage a locking element receiving member on the opposite frame part and in the driving element 11 engaging the locking element. means arranged on a pivot joint associated with the swing bar of the swing bar. The length of the outrigger is determined by the length of the swing bar. Thus, there is also a comprehensive design here, against which the interior can be raised in terms of appearance and touch friendliness. In this embodiment, the axis of rotation of the swing bar also has a considerable distance from the swing axis.

US Patent No. 2,691,289 discloses a swing bar lock in which the swing bar is extendable about its longitudinal axis and for locking in the locking position and in the jib at the end at the opposite end of the swing bar occupies a cylinder lock whose axis lies approximately in the axis of rotation of the swing bar. intersects the swing axis of the swing bar. Also, this swing-bar lock, which is of a different type to that mentioned in the preamble of claim 1, does not show possibilities for a touch-friendly and aesthetically improved lock design and an improved 4

DK 151862 C

utilizing the swing bearing plate dimensions to achieve increased swing torque support.

Preferred embodiments and structural features of the swing bend or ridge of the invention are set forth in the dependent claims.

In addition to the advantages of touch-friendliness and an improved appearance, the measures mentioned in claims 2 and 3 also provide an optimal solution in terms of material consumption, manufacturing costs, space requirements and weight.

The measure of claim 4 is known per se from US Patent No. 4,180,998. It is also compatible with the inventive solution principle, in that the pivot pin can be kept suitably short, whereby the space available within the pivot hub as indicated in claim 17 can be utilized for applying a pivot clamping element.

The measure of claim 5 facilitates easier service.

Claim 6 specifies the various options for blocking the swing bar in the locking rest for 11 at a time, the solution with the locking bearing having to be preferred for reasons of safety against unauthorized breaking. By the measure specified in claim 7, it can be absolutely ensured that the swivel bracket during the driving cannot leave driving style 1 none. In this embodiment, both the pivot biasing element and the pivot clamping element can be omitted to secure the pivot bracket in the driving position for 11 at a time, insofar as such tensioning elements are not desired for other reasons.

Claim 8 provides an opportunity for a simple design of the pivot lock during extensive utilization of commercially available structural elements.

Claim 9 specifies additional measures for aesthetic and simple design.

5

DK 151862 C

Claim 10 specifies different options for use. Removing the key in the latch turn 11 has the advantage of avoiding an unauthorized lock, for example by playful children. The fact that the key is not removed has the advantage that the key is always carried safely and is available for lockdown.

The measures specified in claims 11 and 12 serve to simplify the locking structure.

The measure specified in claim 13 will be understood from the point of view of operating comfort.

The measure of claim 14 reduces the handles required to prepare the vehicle for loosening the pivot lock and turning the pivot bracket from the locking position to the free pivot 11. The pivot clamping member may also be replaced by a suitable pivot torque generating mass distribution. The measure of claim 15 is again particularly encouraging for aesthetic and touch-friendly structure. The measure of claim 16, as already indicated in connection with the claim of claim 4, is advantageous insofar as the space around the pivot pin can be utilized for placing the clamping spring.

The measure according to claim 17, by simple design, provides a covering of the spring and protects against penetration of dirt.

The measure of claim 18 is important not only because a biased clamping element ensures an approximately horizontal spring characteristic throughout the pivot path, but also because the biasing in the drive system secures abutment of the fuse against the fuse receiving member and thus prevents rustling noise during driving.

The measure according to claim 19 is intended to facilitate the mounting of the bias clamp element with bias.

6 υιν ιο 100 ^ υ

The measure of claim 20 further enhances the operating comfort in so far as the swivel bar after releasing the pivot lock and swivel of the swivel bar for the free swivel steering automatically moves quickly to 5 travel distances and is secured there. A stable position of the turnbuckle, in which this is partly not secured and partly does not interfere with a breakthrough in the wheel, is not conceivable in this embodiment, so the risk is excluded that the user of the vehicle can start driving with an unsecured turnbuckle, and that the swivel bar thereon, due to shaking, can engage blocks in the breakthrough in the wheel.

Oe measures as claimed in claim 22 provide a reliable securing of the swing bar in driving position, even when there is no bias of the swing bar towards the driving position. In this embodiment, which, moreover, is not tied to a missing pivot clamp element, one must inevitably, before starting to drive the vehicle, turn the pivot bracket from the locking path 11 to the free pivot 11 and then 20 to the driving path 11 in turn and secure it. there, so that you can start driving the vehicle at all.

The measure of claim 24 provides additional security against an unintentional blockage.

25

In the design of the locking bearing and swing bar according to claim 25, access to the flared swing bar end is further complicated by the first wear step, which means that a turning tool cannot be applied to the swing bar. 30

The measure of claim 26 provides for a simplified mounting of the swing bend or the ridge in the case where the locking bearing is separated from the swing bearing.

Claim 27 specifies an option for the design of the swing bend or the mold, which is particularly suitable for retrofitting.

DK 151862 C

The measure of claim 29 allows for a simple mass production, while the measure of claim 30 further serves to achieve touchability and good appearance.

FIG. 13 shows a swing bar lock according to the invention, where the swing bearing and the locking bed are arranged on a U-shaped hoop; FIG. 14 is a section 1, the line XIV-XIV of FIG. 13, FIG. 15 is a section 1 along line XV-XV in FIG. 13, FIG. 16 is a section along line XV-XV of FIG. 13 in another embodiment of the U-shaped hanger; FIG. 17 is a section along line XV-XV of FIG. 13 in a further altered configuration of the U-shaped hanger; FIG. 18 shows a further embodiment of a swing bar lock according to the invention, in which the swing bearing and the locking bed are separately clamped to the legs of a wheel fork and FIG. 19 is a detail of the embodiment of FIG. 18.

FIG. 1 shows the rear wheel 10 equipped with spokes on a bicycle and the rear wheel fork 12 receiving the rear wheel with its fork legs 12a and 12b. On the fork leg 12a, a swivel bearing 14 is welded and on the fork leg 12b a locking bearing 17. On the swivel bearing 14, a swivel hub 16 is pivotally mounted about a pivot axis 18. In the swivel hub 16 a swivel 20 is pivotally mounted, about its longitudinal axis 22.

The design of the pivot bearing and pivot hub is shown in more detail in FIG. 5 and 6. The pivot bearing 14 is constituted by a pivot bearing plate 14a which is welded to the frame leg 12a and in a cup-like manner is enclosed by an engagement wall 14b. In the middle of the pivot bearing plate 14a stands a pivot pin 14c. The pivot hub 16 exhibits a pivot bore 16a which receives the pivot pin 14c. Further, the pivot hub 16 comprises an annular protrusion 16b which is intended to abut the inner peripheral wall of the engagement wall 14b, and within the annular protrusion 16b a curved channel 16c is formed which is concentric with the pivot pin 14c and the pivot bore 16a. This 9

DK 151862 C

curved channel 16c is intended to receive a bias spring 24. The bias spring 24 is secured with one end 26 of a pin 28 disposed in the hub 16 on the bottom of the curved channel 16c. The other end 29 of the screw spring 24 is hooked onto a pin 30 which is mounted on an anchor disk 32. The anchor disk 32 has the same rounded outline as the engagement wall 14b of the pivot bearing 14. At the mounting, the end 26 of the pin 28 and the end 29 of the pin 30 are secured. and the anchoring member 32 is brought into contact with the hub 16. The hub 16 is then inserted into the pivot bearing 14, whereby the spring 24 is biased by appropriate rotation of the anchor member 32. The anchor member 32 then falls into the rounded outline of the engaging wall 14b so that the bias is maintained. Then, a fuse pin 34 is inserted into a bore 36 of the pivot hub 16 and this fuse pin 34 engages with a ring groove 38 in the pivot pin 14c, but does not prevent rotation of the pivot hub 16 relative to the pivot bearing 14.

In a diametrically through channel 40 in the pivot hub 16, a profile cylinder lock 42 with cam profile is inserted. The duct 40 is part of its length, cf. 6, similarly formed with comb profile, but ends at the other end, cf. 1, as a circular channel. The profile cylinder lock 41 is inserted as shown by the arrow direction 44 in FIG. 6, so that the profile cam 46 comes into contact with the end of the channel portion 48. Then, at the open end of the channel portion 48, an end piece 50 is secured which is secured by a locking screw 52. The profile inside the housing 42 comprises a locking cylinder or core 56 which can be turned by means of a key 54, cf. 1. At the end of the core 56 lying to the right in FIG. 6, the pivot bracket 20 is pivotally and axially flush to the lock core 56 by means of a split 58. A screw torsion spring 60 is anchored to one end of the lock core 56 with its one end not shown, and its other end 62 is intended to abut against the channel portion. 48. When the cylinder lock 42 is inserted into the channel 40, the screw torsion spring 60 is provided with a bias.

As can be seen particularly in FIG. 5 and 7, in the pivot bracket 20 close to the hub 16, but outside this a cutout 10 is formed.

DK 151862 C

64. As can be seen in FIG. 7, there is an unfolded view of the peripheral region of the engaging wall 14b, as in FIG. 5 can be seen in the viewing direction VII, the engagement wall 14 is formed with a notch 66 for receiving a pivot element. In addition to this notch 66 is a curve path 68 formed with a steeply decreasing edge for receiving a pivot element. 70. By means of the cutter 64, a corner 72 is formed on the swing bar 20, acting primarily as a pivot locking element, but also as a pivot locking element.

In FIG. 7 engages the pivot element 72 with the pivot element receiving groove 66; this position corresponds to the position of the swing bar 20, as shown in FIG. 1 is shown in dashed lines. The bias generated by the screw torsion spring 60 searches in FIG. 7 to pivot the pivot member toward the pivot member receiving slot 66. The FIG. 7 in Hing for the pivot bracket 20 is referred to as the pivot lane 11 in the ring. This pivot locking position can be set such that the key can be removed from the cylinder lock 42 and the pivot bracket 20 thus lockably lockable; in that case, the pivot element 72 cannot come out at all from the pivot element receiving slot 66. However, it is also conceivable that the embodiment shown in FIG. 7 does not allow the key to be removed from the cylinder lock 42. In that case, the engagement of the pivot element 72 in the notch 66 is secured by the spring force from the screw torsion spring 60. When the pivot bracket 20 is in the position shown in FIG. 7, the swivel bracket 20 can be swiveled from the one shown in FIG. 1 is a dashed position to the position shown in FIG. 1 in full line. In the embodiment shown in FIG. In the dashed position, namely the driving position 11, the swing bar 20 is out of engagement with the wheel 10. In order to make it possible to swing the swing bar 20 to the position shown in FIG. 1 in a fully drawn position, the pivot bracket 20 must first be turned against the action of the screw torsion spring 60 so that the pivot member 72 exits the slot 66 to receive it. Only then can the pivot bracket 20 be pivoted, 11

the pivot element 72 now moves along the curve path 68 until the pivot element 72, which from now on acts as a pivot element, falls into the portion adapted to receive the pivot element, i.e.. behind the flank 70. After the pivot element 72 has exceeded the flank 70, under the influence of the screw torsion spring 60, the pivot element 20 can rotate so far in the direction of the arrow 76 that the pivot bracket 20 reaches a pivot locking direction. In this pivot locking 11, the locking core 56 has reached such an angular path with respect to the cylinder lock 42 that the key 54 can be pulled out so that from now on the swivel bar can no longer be rotated. The swing bar 20 is then in the fully extended position of FIG. 1, and therefore can no longer be turned, and - because of the engagement between the pivot element 72 and the flank 70 arranged to cooperate therewith - from now on can also no longer be pivoted. Wheel 10 is locked. FIG. 8 shows the engagement between the pivot element 72 and the flank 70 arranged to cooperate therewith. 8 shows a partial unfolding of the engagement wall 14b, seen in the direction of arrow VIII in FIG. 5th

If the bike is to be unlocked, key 54 must be inserted again. Then, by means of the key 54, the swing bracket 20 can be turned against the action of the screw torsion spring 60 from the one shown in FIG. 8 as shown in FIG. 8, but in a broken line, the pivot release path 11 showed. The screw spring 24 then swings the swing bar 20 back from the one shown in FIG. 1 in full line position to the dashed position, whereby the pivot element 72 slides across the curve path 68 and finally, under the influence of the screw torsion spring 60, again snaps into the pivot element receiving groove 66. A stop finger 80 positioned on the engagement wall 14b prevents swinging bend 20 from preventing swinging FIG. 1 dashed position.

Since the large bar length of the swing bar 20 can cause a locking of the swing bar 20 in the embodiment shown in FIG. 1, only by the engagement between the pivot element 72 and the pivot element receiving flank 70, as shown in FIG. 8, may 12

DK 151862 C

In an extreme case, the lock is equipped with a latch 17. This latch 17 cooperates with a latch 82 on the free end of the latch 20, cf. 1. The locking bearing 17 and the cooperating locking catch 82 are shown in detail in FIG. 2-4. The latch 17 includes a two-stage input slot 17a, 17b having a first, wider step 17a and a second narrower step 17b. Adjacent to the narrower step 17b in the slot, a uptake chamber 17c is formed upwards. The wider wear stage 17a is dimensioned so that - as shown in FIG. 2 - can record and control the full round cross section of the swing bar. The end region of the swing bar is, as shown in FIG. 1 and 2, by means of a two-sided milling formed with a flattened end region 84. This flattened end region can just pass the narrower wear step 17b when the swing bar as shown in FIG. 3 is in the pivot unlock position in which it can be held against the action of the screw torsion spring 60 by turning the key 54. When the pivot bracket 20 has entered the latch 17, as shown in FIG. 3 and the key is released, then the swing bar can rotate into the pivot lock 11 shown in FIG. 4. In this pivot locking position, the key can be removed so that the swing bar can no longer be turned. The swing bar is blocked from re-exiting the latch 17, firstly because the flared end region 84 can no longer pass through the narrower wear step 17b, and secondly, because the latch 82 abuts against a bearing surface 17d of the recording space 17c. As can be seen in FIG. 2, the full cross section of the swing bar penetrates so deep into the wear step 17a that with a turning tool it is impossible to enter the flattened end area 84 and thereby rotate the swing bar by breaking the cylinder lock 42.

The modified embodiment shown in FIG. 9-12, partially corresponds to that of FIG. 1-8, and to the extent consistent, the corresponding parts are provided with the same reference numerals, but each time incremented by the number 100.

DK 151862 C

In changing the embodiment of Figs. 1-8 to the one of Figs. 9, the screw spring which serves as a swing biasing means lapses together with the associated auxiliary parts. FIG. 10 shows an unfolding of the engaging wall 114b as viewed in the arrow direction X. FIG. 10 again shows the pivot element receiving groove 166 which is designed in a similar manner to FIG. 7. Shaped in another way, however, the pivot member 172, which is formed as a protrusion on the otherwise fully rounded cross-section of the pivot bar 120. Furthermore, the curve path and the pivot element receiving member have lapsed. Close by, but separated from the pivot element receiving groove 166 by means of a tip stand 188, is a pivot element impact face 190. The direction of bias indicated by an arrow 176 is the inverse of that of FIG. 1-8. In the embodiment shown in FIG. 9-12, the latch appears only in latch bed 117; The locking position is shown in FIG. 12. In order to unlock the swing bar lock, the swing bar is brought into the position shown in FIG. 11, the pivot path 11 enables the end of the pivot bracket to exit from the latch 117. When the pivot bracket now extends from the one shown in FIG. 1 fully extended position falls into the dashed position - assuming that the key has been released - the swing bar 120 rotates back in the position shown in FIG. 10, thanks to the effect of the screw torsion spring present in this embodiment similar to the one shown in FIG. 6. When the swing bar is in this pivot position and approaches the one shown in FIG. In the dashed position, the pivot element 172 abuts against the pivot element impact surface 190. The pivot position 120 of the pivot bracket 120 thus conditioned is designated as impact path 11. In this impact position 11, the pivot element 172 cannot enter the pivot element receiving groove 166. This ensures that the swing bar 120, as long as it is in the impact position, continues to engage the spokes in wheel 10. With the swing bar in this position the wheel cannot be rotated. In order to enable the wheel to be turned, the swing bar must be brought into the position shown in FIG. 10 in dotted line 14

DK 151862 C

plotted turn-locking device corresponding to the one shown in FIG. 1 dashed driving position. To this end, it is necessary to rotate the swing bar 120 out of the full bar of FIG. 10 plotted against the effect of the screw torsion spring, i.e. toward the direction of arrow 176 until the pivot locking member 172 can step over and past the tip stand 188. Then the swing bar 120 is pivoted into the one shown in FIG. 1, and the pivot member 172 may fall into the pivot member receiving slot 166, such as the one shown in FIG. 10 is shown in dotted line. Now the swing bar is in the driving position and it is also secured. Also in this case, the fuse may be based solely on the spring bias from the one shown in FIG. 6, or further, the pivot member 172 and the pivot member receiving groove 166 may be aligned so that in the embodiment shown in FIG. 10 in the position shown in dashed line, it is possible to remove the key so that the swing bar 120 can thus be made removable.

As can be seen in FIG. 1, the pivot bearing 14 and the locking bearing 17 are independently welded or otherwise attached to each fork leg 12a and 12b, respectively. In order to facilitate the placement of the pivot bearing and the locking bearing, it is possible, when the pivot hub 16 is removed, to connect the pivot bearing 14 and the locking bearing 17 with one another by means of a mounting connecting means which compulsively keeps the pivot bearing 14 and the locking bearing 17 at the correct distance between them and orientation. This mounting connector may further be arranged to allow some axial displacement of the locking bearing 17 relative to the pivot bearing 14, corresponding to the extent in which the locking lug 82 is narrower than the receiving space 17c.

The mounting connector may be a simple and inexpensive plastic part which, during storage and transport, joins together pivotal and locking bearings 14 and 17, respectively, and which can be removed and discarded after locking on the bicycle frame so that it can then be mounted 15

DK 151862 C

the pivot hub 16 with the pivot bracket 20 on the pivot bearing 14. It is readily possible to design the mounting connector so as not to interfere with the welding or other attachment of the pivot bearing 14 and the locking bearing 17.

In FIG. 13, analogous parts are provided with the same reference numerals as in the embodiment of FIG. 1-8, but this time in each case increased by the number 200. In the FIG. 13, the pivot bearing 214 and the barrier bearing 217 are mounted on a U-bar 290, namely on its legs 290a and 290b, respectively, which are interconnected by means of a bridge 290c. In the legs 290a and 290b of the U-bar 290, two long-shaped long holes 290d are formed which extend parallel to the bridge 290c. Through the long holes 290d, tightening screws 290e are inserted, whose tool engagement heads 290f are in an outer case 290g and whose ends 290h are screwed into each claw 290i. Each claw 290i, with its foot 290k, is disposed in the second outer rim 2901 of the long hole 290d, and in this fold can be rotated about the axis of the screw 290e so that the claw can grip the relevant leg in a bicycle frame from the outside or from the inside. By displacing the screw 290e along the long hole 290d, it is possible to adjust the lock to different frame fork widths, a further adjustment being achieved by turning each claw 290i about the axis of the clamping screw 290e.

In the FIG. 15, the U-bar 290 is formed with a U-profile, which is closed by a cross-section T-shaped U-bar 290m.

In the FIG. 16, the U-bar 290 'is also U-shaped in cross-section and closed by a U-shaped filler body 290n, which also has a U-shaped cross-section. The entire U-bar 290 'is molded with a plastic covering 290o.

In the embodiment of FIG. 17, the U-bar 290 "is shaped with a T-shaped cross-sectional profile and is also molded.

In the embodiment shown in FIG. 18, analog parts are again provided with the same reference numerals as in FIG. 1, but this time in each case increased by the number 300. In this embodiment, the swivel bearing 314 and the locking bearing 317 are clamped separately to the fork legs 312a and 312b, respectively, as follows:

The swing bearing 314 is provided with a bearing ring 394 which is intended to abut against the wheel fork leg 312a. On the inner circumference of the ring 394, an undercut ring groove 394a is formed in which two claw inserting notches 394b are cut at two diametrically opposite locations. The wheel fork leg 312a is enclosed by a U-shaped clamping bracket 394c, on the free ends of which are claws 394d. As can be seen in FIG. 19, the claws 394d engage the undercut ring groove 394a. The mounting is carried out so that after the U-shaped clamping hanger 394c is brought into abutment against the wheel fork leg 312a, the claw inserting notches 394b are brought into alignment with the claws 394d, and the ring 394 is then inserted over the claws 394d until they are reached. the same depth as the undercut ringnote 394a. Then, the pivot bearing 314 can be turned to the one shown in FIG. 18 and 19, whereby the claws 394d engage the cut ring groove 394a. Now, in a threaded bore 394 formed in the bottom portion of the U-shaped clamping bracket 394c, a clamping screw 394f can be brought into contact with the wheel fork leg 312a and tightening the claws 394d relative to the cut ring groove 394a. The clamping screw has a screw head 394g with an hexagon, which is connected to the threaded part of the screw 394f through a weakening roller 394h. After a predetermined tightening is reached, the head is turned 394g off under the influence of the clamping tool so that the clamping device can no longer be loosened.

The entire clamping device can be covered with a plastic injection molded cover 394i and exhibiting a snap bead 394k which can be intercepted in a ring recess 3941 in the pivot bearing 314.
