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

Such a swing bar lock is known from US Patent No. 4,180,908, in which the swing lock in the driving position is obtained by a recess in the swing bar within the swing hub cooperating with a recess in a swing pin. In this embodiment, the swing bar with its axis of rotation is necessarily positioned laterally with respect to the swing axis, so that an asymmetrical design of the swing bar lock can be provided, which can be raised objectively from both a viewpoint of touch friendliness and a viewpoint of appearance.

The object of the invention is to provide a swivel bracket of the aforementioned type with an improved design from the aforementioned points of view.

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 20 approximately circular outline about the pivot axis without constructive problems, this circular outline in diameter being similar 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 of its simplicity 25 also being aesthetically satisfactory, which form can be further improved in aesthetically and touch-friendly terms in that it The end surface of the pivot hub lying away from the pivot bearing plate as claimed in claim 3 extends the arc shape about the axis of rotation, i.e. 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 site of engagement of the securing element and the securing element receiving means can be placed in an undesirable increase in the design dimensions.

However, this protrusion on the pivot bearing must here extend far beyond the dimension of a pivot bearing / practically over the entire length of the pivot bracket, so that one cannot in the narrower sense speak of a locking element receiving member in the pivot 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 there is also a design which is unsatisfactory in terms of aesthetic appearance and touch friendliness.

Furthermore, a swing bar lock is known, in which the swing bar is pivotally mounted about its longitudinal axis in a swing hub 25 and its free end carries a locking element which engages in the locking position in a locking element receiving member on the opposite frame part and in the driving position. The length of the boom is determined by the length of the swing bar, and thus there is also an elaborate design against which objections regarding appearance and touchability can be raised. 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 swivel bracket in which the swivel bracket is extendable about its longitudinal axis and for securing in the locking position and in the driving position at its end facing the swivel bearing, a cylinder lock whose axis lies approximately in axis of axis of rotation and approximately intersects axis of axis of swing. Also, this pivot bend 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 utilization of the pivot bearing plate dimensions to obtain increased pivot support torque. .

Preferred embodiments and constructive features of the swing bar latch according to 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 rhyme available within the pivot hub as stated in claim 17 can be utilized for applying a pivot clamping element.

The measure of claim 5 facilitates easier operation.

Claim 6 specifies the various options for blocking the swing bar in the locking position, 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 travel cannot leave the driving position. In this embodiment, both the pivot biasing element and the pivot biasing element can

is omitted to secure the swing bar in the driving position, insofar as such clamping elements are not desired for other reasons.

Claim 8 provides an opportunity for a simple design 5 of the pivot lock during extensive use of commercially available structural elements.

Claim 9 specifies additional measures for aesthetic and simple design.

Claim 10 specifies different options for use.

10 Removing the key in the locking position 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 measure of claim 11, while achieving aesthetic shape and touchability, provides optimal utilization of the diameter of the pivot bearing plate to support the pivot bracket in driving position and locking position. The sidewall can thereby further take over the function of a protection against penetration of dirt and moisture. The locking element receiving means and the locking element receiving means are in their direction of action parallel to the pivot axis. Similarly, the securing element performs a movement substantially parallel to the pivot axis when it moves between either a free pivot position and partly the pivot position or the locking position, and an unintentional clamp which cannot be excluded by U.S. Patent No. 4,180,998. swivel lock, is thereby avoided.

The measures specified in claims 12 and 13 serve to simplify the locking structure.

The measure specified in claim 14 will be understood from the point of view of operating comfort.

The measure of claim 15 reduces the handles required for the preparation of the vehicle for solution

of the pivot lock and a pivot of the swing bar from the lock position to the free pivot position. The pivot clamping element may also be replaced by a suitable pivot torque generating mass distribution. The measure mentioned in claim 16 is again particularly encouraging for aesthetic and touch-friendly construction. The measure of claim 17, as already indicated in connection with the claim of claim 4, is advantageous in that the space around the pivot pin can be utilized for positioning 10 of the clamping spring.

The measure according to claim 18, by simple design, provides a cover of the spring and protects against penetration of dirt.

The measure of claim 19 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 driving position ensures abutment of the locking member against the locking element receiving means and thus prevents noise from underrun.

The measure of claim 20 is intended to facilitate the mounting of the bias clamp element with bias.

The measure of claim 21 further enhances the operating comfort in so far as the pivot bracket after releasing the pivot lock and pivot of the pivot bracket to the free pivot position automatically moves quickly to the driving position and is secured there. A stable position of the swing bar, in which this is partly not secured and partly does not intervene in a breakthrough in the wheel 30, is not conceivable in this embodiment, so that the risk is excluded that the user of the vehicle can start driving with unsecured swing bar, and that, due to shaking, the pivot bar may interlock in the breakthrough in the wheel.

The measures specified in claim 23 provide a reliable securing of the swing bar in the driving position, even when there is no biasing of the swing bar 'towards the driving position. In this embodiment, which is otherwise not tied to a missing pivot clamp element, one must inevitably, before starting to drive the vehicle, turn the pivot bracket from the locking position to the free pivot position and then to the driving position and secure it there to can start driving with the vehicle at all.

The measure of claim 25 provides additional security against accidental blocking.

In the design of the locking bearing and the swing bar according to claim 26, access to the flared swing bar end is further impeded by the first wear stage, which means that a turning tool cannot be applied to the swing bar.

The measure according to claim 27 causes a simplified mounting of the swing bar lock in the case where the locking bearing is separated from the swing bearing.

Claim 28 provides an option for the design of the swing bend lock, which is particularly suitable for retrofitting.

The measure of claim 30 'allows for simple mass production, while the measure of claim 31 further serves to achieve touchability and good appearance.

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 bar 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 swing bearing 14 is formed by an 8 DK 15186 2 B j i! Oh! swing bearing plate 14a, welded to the frame leg 12a and enclosed in a beaker-like manner by an engaging 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 <5 pin 14c. Further, the pivot hub 16 comprises a ring protrusion 16b 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 curved channel 16c is intended to receive a bias spring 24. The bias spring 24 is hooked with one end 26 of a pin 28 located in the hub 16 on the bottom of the curved channel 16c. The other end 29 of the screw spring 24 is wrapped on 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 on 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. Then the hub 16 is inserted into the pivot bearing 14, whereby the spring 24 is held pre-tensioned 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. Channel 40 is part of its length, cf. FIG. 6, also formed 30 with combat profile, but ends at the other end, cf. FIG. 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 duct portion 48. Then, at the open end of the duct portion 48, an end piece 35 50 is secured which is secured by a locking screw 52.

the linder lock 42 comprises a lock cylinder or core 56 which can be rotated by a key 54, cf. FIG. First

At the end of the core 56, located to the right of FIG. 6, the pivot bracket 20 is pivotally fixed and axially flush 5 to the locking core 56 by means of a split 58. A screw torsion spring 60 is anchored in its locking end 56 by one end, and its other end 62 is intended to lie 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 of this, a cutter 64 is formed. As can be seen in FIG. 7, there is an unfolded view of the peripheral area of the engagement wall 15b, 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, a curve path 68 is formed which is adapted to receive a pivot element 20, steeply falling flank 70. Due to the milling 64, a corner 72 is formed on the swivel bracket 72, 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 slot 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 rotate the pivot element toward the pivot element receiving groove 66. The pivot position 20 of the pivot bracket 20 shown in FIG. 7 is referred to as the pivot position. This pivot locking position may 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 overhead cannot exit from the pivot element receiving slot 66. However, it is also conceivable that the pivot locking position shown in Fig. 7 does not allow the key to be taken out of 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 spring torsion spring 60. When the pivot bracket 20 is in the pivot locking position shown in FIG. 7, the pivot bracket 20 cannot be pivoted from the dashed dot shown in Fig. 1. position in the fully drawn position of Fig. 1. In the dashed position of Fig. 1, namely the driving position, the pivot bracket 20 is out of engagement with the wheel 10. In order to be able to pivot the pivot bracket 20 to the Fig. 1 with 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 element 72 emerges from the slot 66 for receiving it 15. The yoke 20 is pivoted as the pivot element 72 now moves along the j curve path 68 until the pivot element 72, which from now on acts as a pivot element, falls into the portion arranged to receive the pivot element, i.e..

20, at the rear of the flank 70. After the pivot element 72 has exceeded the flank 70, under the influence of the screw torsion spring 60, the pivot member 20 can rotate so far in the direction of the arrow 76 that the pivot 20 reaches a pivot lock position. In this pivot lock position, the locking bar 56 has reached such an angular position with respect to the cylinder lock 42 that the key 54 can be pulled out so that the swing bar can no longer be turned from now on. The swing bar 20 is then in the fully drawn position of FIG. 1, and therefore can no longer be rotated, and - because of the engagement 30 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 engaging wall 14b in the direction of arrow VIII in FIG. 5. j

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.

5 8, but in interrupted line, showed the turn release position.

The screw spring 24 then swings back the swing bar 20 from the full line position shown in FIG. 1 to the line dotted position, whereby the pivot element 72 slides across the curve path 68 and finally, under the influence 10 of the screw torsion spring 60, snaps again into the pivot locking element 66. A stop finger 80 placed on the engagement wall 14b prevents the swinging bar 20 from moving past the one shown in 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 be insufficient and still allow a violent breaking of the swing bar latch in extreme cases, 20 the latch is provided with a latch 17. This latch 17 cooperates with a latch 82 on the free end of the latch 20, cf. FIG. 1. The locking bearing 17 and the cooperating locking catch 82 are shown in detail in FIG. 2-4. The locking bearing 17 comprises 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 of the slot, an uptake compartment 17c is formed at the top. 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 rotation

of the key 54. When the swing bar 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 position shown in FIG. 4. In this pivot-5 rest 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 stage 17b, and secondly, because the latch 82 abuts against a contact surface 17d of the recording space 17c. As can be seen in FIG. 2, the full cross section of the swing bar penetrates so deeply into the wear step 17a that with a turning tool it is impossible to enter the flattened end region 84 and thereby rotate the swing bar by destroying 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, however each time incremented by the number 100.

In changing the embodiment of FIG. 1-8 to that of FIG. 9, the screw spring which serves as a swing biasing means lapses together with the associated auxiliary parts. Pig. 10 shows an unfolding of the engagement wall 114b as viewed in the arrow direction X.

In FIG. 10 again shows the pivot element receiving groove 66 formed in a similar manner to FIG. 7. Shaped in another way, however, is the pivot element 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 a spike 188, is a pivot element impact face 190. The bias direction, indicated by an arrow 176, is the inverse of the

in 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 shows the pivot release position in which the end of the swing bar can step out of the locking bed 117. When the swing bar is now from the position shown in FIG. 1 fully extended position falls into the dashed position - assuming that the key is released - the swing bar 120 rotates back in the position shown in FIG.

10 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 is approaching 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 thus conditioned is referred to as the impact position. In this impact position, 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 the wheel 10. With the swing bar in this position, so the wheel is not turned. In order to enable the wheel to be turned, the swing bar must be brought into the position shown in FIG. 10 in the dotted line, the turn-lock position 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 action of the screw torsion spring, i.e. toward the direction of arrow 176 until the pivot member 172 can step over and past the tip 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 166/35 as 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 can either be based solely on the spring bias from the one shown in FIG.

6, or further, the pivot element 172 and the pivot element 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.

10 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 taken away, to connect the pivot bearing 14 and the locking bearing 17 with one another by means of a mounting connecting means which forcibly holds the pivot bearing 14 and the locking bearing 17 at the proper distance between them. and orientation. This mounting connector may further be arranged 20 to allow some axial displacement of the locking bearing 17 relative to the pivot bearing 14, corresponding to the extent in which the locking catch 82 is narrower than the receiving space 17c.

The mounting connector may be a simple and inexpensive plastic part which already connects associated pivoting and locking bearings 14 and 17 with each other during storage and transport, and which after removal of the lock on the bicycle frame can be removed and discarded so that the pivot hub can then be mounted. 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 fastening of the pivot bearing 14 and the locking bearing 17.

In the embodiment of FIG. 13, the swivel bearing 214 and the locking leg 217 are arranged 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, the tool engagement heads 29O of which lie in an outer case 290g, 10 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 moving the screw 290e along the long hole 29Od, it is possible to adjust the lock to different frame fork widths, a further adjustment being achieved by rotating each claw 290i about the axis of the clamping screw 290e.

In the embodiment shown in FIG. 15, the U-bar 290 is formed with a U-profile, which is closed by a cross-section T-shaped U-bar 29Om.

In the embodiment shown in 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 overall U-bar 290 'is molded with a plastic covering 290o.

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 above 5 opposite locations. The wheel fork leg 312a is enclosed by a U-shaped clamping bracket 394c, on free ends provided with claws 394d. As can be seen in FIG. 19, the claws 394d engage the undercut ring groove 394a. The mounting ring 10 is designed so that after the U-shaped clamping bracket 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 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 tighten the claws 394d relative to the undercut ringnote 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 groove 394h. After a predetermined tightening is reached, the head 394g is rotated under the influence of the tightening tool so that the clamping device can no longer be loosened.

The entire clamping device may be covered with a plastic injection molded cover 30 394i and exhibiting a snap bead 394k which. may be intercepted in a ring recess 3941 in pivot bearing 314.

The locking bearing 317 is similarly attached to the second wheel fork leg 312b.

The swing bar lock is provided with swing bar 320 of such length that it approximately corresponds to the largest opening widths between the wheel fork legs 312a and 312b. At smaller fork width wheel forks, the pivot bearing 314 and the locking bearing 317 are shifted downward, corresponding to the downward diverging course of the wheel fork legs 312a and 312b. For example, if it is not sufficient to displace the two bearings 314 and 317 downward to the same extent in order to adjust the horizontal distance between the bearings 314 and 317 to the greater length of the swing bar 320, it may be possible, e.g. displacing the locking bearing 317 further downward than the pivot bearing 314, thereby increasing the distance between them. In such cases, too, to ensure the proper interaction between the bearings 314 and 317 and the pivot bracket 15 320, the bearings 314 and 317 can be rotated relative to the U-shaped clamping braces 394c.
