Description

Bicycle with at least one tool-less removable pedal

DESCRIPTION

The invention relates to a bicycle with at least one tool-free removable pedal, which is fastened to a arranged on the bicycle anti-theft bracket.

Such a bicycle is known from DE 196 14 494 C1. This bicycle has a crank with two cranks, to each of which a pedal is attached. This is in every crank an adapter

screwed, which has a variety of mounting bolts. On this adapter, the pedal with a connected to an axis of the rack adapter counterpart is attachable. in the

Adapter counterpart is a locking device integrated, which cooperates in the locked state with the fastening bolts of the adapter. Furthermore, an anti-theft mounting bracket is attached to the frame of the bicycle, which is the adapter

having corresponding fastening bolt. The

Locking device is designed for example as a lock and the lock is unlocked, for example, with a key relative to the adapter. In the unlocked state, the pedal can be removed from the adapter and on the

Anti-theft bracket attached and locked with this. In normal operation of the bicycle with arranged on the pedal arms of the pedal pedal, the locking device and the lock can easily pollute and beyond penetrating moisture are impaired in their function. In addition, the locking device causes a significant additional weight of the normally executed in lightweight construction pedal.

The invention has for its object to provide a bicycle with at least one tool-free removable pedal, the

reliable and trouble-free with one on the bike

arranged anti-theft holder is connectable.

This problem is solved by the fact that

Anti-theft bracket has a lock which is lockable with the axis of the pedal. It is the

Anti-theft bracket so prefers the bike

arranged that this easily accessible and thus easy to handle. Furthermore, the castle is on the

Anti-theft bracket so arranged that it is better protected in each case against an urgent dirt and moisture than may be the case on a pedal crank. In addition, only one lock needs to be arranged on the anti-theft bracket. This allows the pedal to be like a conventional pedal in

Be lightweight and designed in particular in a

Replacing the pedal as a result of a defect or other

Demands on a pedal is thus a cost-effective replacement possible.

In a further development of the invention, the axis of the pedal at a free end on a guide portion and a holding portion. With the guide section, the axis of the pedal is either in an adapter connected to the crank or in a

Receptacle of the anti-theft holder used and fixed in position. For this purpose, the guide portion, for example, a hexagon, in the adapter or the Recording device of the anti-theft holder is used. In particular, when mounted on the adapter is thereby ensured that the axis of the pedal is fixed against rotation and thus during a pedaling movement of the

Bicycle in any case, a rotational movement between the

ball-bearing pedal and the axle takes place. These

Anti-rotation is but when attached to the

Anti-theft bracket not required. The one of the

Guide section independent holding section acts with an easy to handle locking device on the adapter

or together with the castle. This embodiment is particularly advantageous in terms of a functionally reliable handling. In a further embodiment of the invention, the holding portion is formed by a circumferential annular groove. In this annular groove, either the locking device or the lock engages in a suitable manner. Preferably, in a further embodiment, the lock of the anti-theft holder on a bolt which engages in the locked state in the annular groove. Thus, regardless of the rotational position of the guide section in the

Anti-theft bracket has been introduced, a

reliable and easy locking possible. In a further development of the invention, the anti-theft holder is mounted on a frame and / or a fork of the bicycle. In this case, the anti-theft holder is arranged so that the pedal is inserted, for example, through a rim into the receiving device of the anti-theft holder. As a result, the rim is prevented from rotating and also the rim can not be disassembled from the bicycle. In the context of the invention, it is also possible, the anti-theft holder so to arrange that when pedal is used simultaneously or alternatively a pedal crank is prevented from rotating.

In a further embodiment of the invention, the

Anti-theft mounting bracket on a housing and / or a holding plate, which is welded or soldered to the frame and / or a fork. The housing or the holding plate is preferred without the bicycle manufacturer during the production process

significant additional effort associated with the frame and / or fork. Incidentally, the fork may be the front fork or else a rear fork independent of the frame of the bicycle, which is installed, for example, in a rear-wheel-sprung embodiment of the bicycle. On a thus prepared bicycle, the inventive

Anti-theft device can also be retrofitted easily. In the housing, the lock is preferably used so that this is not removable in normal operation. For one

However, the lock can be repaired by an authorized person using, for example, a corresponding person

Tool key be disassembled. For safety reasons, however, the lock is not removable when the pedal is inserted. On the retaining plate, the housing for the lock can be fastened so that the housing can not be disassembled from the retaining plate when the lock is inserted, in particular when retrofitting. For this purpose, the housing, for example, have holders, for example in the form of screw, which are not accessible when the lock is inserted.

In development of the invention, the

Anti-theft device on a housing that with the

Frame and / or a fork screwed, riveted or jammed. This embodiment has the advantage that no modification to the frame or a fork is necessary. Therefore, this is suitable Especially suitable for retrofitting any bicycle. In the context of this embodiment, the housing can be attached directly or with the interim disposal of a holding part of the bicycle. This is in particular also provided, existing fastening devices on the bike

For example, it is customary for the attachment of a brake for the front wheel and / or the rear wheel on the

Provide frame or a fork receiving bolts (so-called pivots) on which the brake is placed and secured. Here, a U-shaped bracket can be installed to stabilize the frame or a fork, which prevents expansion of the frame or a fork even with a violent braking operation. Such a bracket may for example be provided as a replacement part with a holding plate or a bracket with which the housing is subsequently connectable. In this embodiment, the connection is of course designed so that it is not solvable when inserted lock. In the context of the invention, however, it is also provided to form the bracket or the holding plate or the bracket integrally directly with the housing. Depending on the location of the

Recording bolt is even at a conceivable distance of

Fasteners for the strap on removing the

Theft prevention holder with the pedal inserted by other frame parts not possible. For example, when installing on a front fork, the bracket may be formed so that this on one side of the front fork and the

Anti-theft device on the other side of the

Front fork are arranged so that when the pedal is used even with an attempted disassembly of the front seat of the bracket with the Theftststurcherungseinrichtung can not be stripped off the front fork. The anti-theft device with the pedal used is inseparable from the bicycle

jammed. In a further embodiment of the invention are two

Anti-theft devices installed on the bike. In this case, it is provided in particular, an anti-theft device on the frame and an anti-theft device on the

Provide front fork. Both anti-theft devices are preferably operable with a common key.

Further development of the invention is the anti-theft holder with a securing device, for example in the form of a

Safety chain, a safety rope or a safety bar can be connected or combined. The securing device can be a stationary component, such as a

Street lamp, are looped and fixed to the bicycle using the anti-theft bracket. For this purpose, the securing device, for example, two eyelets on the axis of the pedal before the insertion in the

Receiving device are attached. After the pedal is attached to the antitheft mount, the eyelets between the antitheft mount and the pedal are unsolvable

trapped. The fact that no separate lock is required for this backup device, this is inexpensive to deploy and very easy to stow. It is within the scope of the invention also possible to provide the securing device at one end with a guide portion and a holding portion and to provide at the opposite end with an over the securing device überstreifbaren eyelet. It is then the

Sicherungsseinfichtung, which in turn may be a safety chain or a safety rope, wrapped around a stationary component optionally with the further inclusion of a bicycle part and then passed with the guide portion and the holding portion through the eyelet. Finally, the holding section is inserted into the receiving device of the anti-theft holder. This form of backup provides an alternative or at least two Theft protection brackets installed on the bicycle complement the safety form with a pedal.

Further advantageous embodiments of the invention can be found in the description of the drawings, in which one in FIGS

illustrated embodiment of the invention is described in detail.

a retrofittable anti-theft bracket with a pedal in an insertion position, a retrofittable anti-theft bracket with an inserted pedal, a retrofittable and frame mounted bicycle anti-theft bracket with a pedal in an insertion position, a retrofittable anti-theft bracket with an inserted pedal mounted on a frame of a bicycle; To be welded to a frame of a bicycle mounting plate on which an anti-theft bracket is mounted with an inserted pedal and mounted on a front fork U-shaped bracket with a bracket on which a

Anti-theft mounting bracket is mounted with an inserted pedal. FIG. 1 shows a retrofittable anti-theft holder 1, which has a housing 2 accommodating a lock 3. The housing 2 has a lateral receiving device 4, in which a

Guide portion 5 and a holding portion 6 of a pedal 10 is used. The receiving device 4 and thus de complete anti-theft holder 1 is permanently connected to a clamp 7 which is fastened to a frame 8 and / or a fork (Figure 3) of a bicycle. In this case, the attachment is such that the anti-theft holder 1 after the successful installation can not subsequently be removed or removed. The assembly can be done, for example, in the form that the clamp 7 on the frame 8 by means of a non-detachable

Screw (shown by the center line 9) is fastened. The non-releasable screw connection can be realized, for example, by a screw head which can only be rotated in one direction or by a screw head which turns off or shears off during the starting operation. The lock 3 is actuated by means of a key 1 1, wherein the insertion opening for the key 1 1 in the lock 3 of a displaceable

Cover 12 is closed with the key removed 1 1. As a result, the insertion opening is reliably protected against penetrating dirt or against ingress of moisture.

The pedal 10, which is normally attached to an adapter bolted to a pedal arm of a pedal crank of the bicycle and fixed by means of a manually releasable locking device, has a pedal body 13, the structure and

Embodiments results in particular from Figures 3 and 4. The pedal body 13 has inter alia a central axle body 14 (FIG. 3) in which an axle 15 is rotatably mounted (ball).

End side, the axis 15 on the out of the tread 13th

outstanding area the holding section 6 and the

Guide section 5 on. The holding section 6 is of a encircling annular groove formed in the locked state of the

Lock 3 a spring-loaded latch, which is moved back by a rotation of the key 1 1 in an unlocked position engages. The guide section 5 has a hexagonal profile which, in the event of interaction with an adapter bolted to the crank, ensures that the axis is secured against rotation in the

Crank is fixed. This ensures that at one

Pedaling the bicycle crank by a cyclist

excluding the (ball-bearing) Tretkörper 13 a

Rotary movement relative to the axis performs.

Figure 2 shows the components shown in Figure 1, wherein the pedal 10 with the guide portion 5 and the holding portion 6 in the

Receiving device 4 of the anti-theft holder 1

inserted and locked. The pedal 10 is thus fixed to the

Theft prevention holder 1 connected and can only be released by unlocking the lock 3 and out of the

Recording device 4 are removed. Figure 3 shows the anti-theft mounting bracket 1 mounted on a frame 8 and / or a fork. In the frame 8, a partially illustrated rim 16 with a rim 17 and spokes 18 is rotatably supported. On the frame 8 is still a

Stud bolt 19 welded to which a likewise only partially illustrated brake lever 20 is fixed with one eye. In order to safely avoid widening of the frame 8 during a braking operation, a U-shaped bracket on the frame 8, the rim 16 is mounted and placed on the two receiving bolts 19, the two 16 comprising the rim frame tubes or

Fork tubes are arranged, plugged and fastened.

FIG. 4 shows, analogously to FIG. 2, the pedal inserted into the receiving device 4 of the anti-theft holder 1 and locked 10. As a result, the rim 16 is prevented from rotating and beyond that can not be dismantled and removed from the frame 8. In addition, during or before the insertion process of the pedal 10 in the receiving device 4, a stationary component such as a lantern looping chain (or a corresponding steel cable) are placed with two end eyelets on the axis 15 of the pedal 10. In the locked state of the pedal 10, the chain is held with the eyelets between the housing 2 of the anti-theft holder 1 and the pedal body 13 of the pedal 10. Through such a chain is the bike

additionally secured in place. As for the attachment of the chain without a lock of its own there is a further weight advantage and the chain can be easily stowed when not in use.

Figure 5 shows one on a frame of a bicycle

to be welded holding plate 2, on the one

Anti-theft holder 1 is mounted with an inserted pedal 10. The holding plate 21 is in the production of a bicycle to the (not shown here) frame 8 and / or a fork welded (or soldered) and painted together with the other parts. On this plate 21, the housing 2 a of the anti-theft holder 1 in the production of the bicycle or even attached later, for example, screwed tight, with one or more mounting screws by a

Receiving opening 28 for the lock 3a are inserted into corresponding holes in the housing 2a and are screwed to the holding plate 21. For example, the

Fixing screws may be formed as Allen screws, which unwound through the receiving opening 28 with a

Allen key are accessible. After this mounting operation, the lock 3a is inserted into the receiving opening 28. It can this assembly process done so that the lock 3a snaps into the receiving opening 28 in a suitable manner during the insertion process and only with a special workshop key

For example, in a repair case again from the

Receiving opening 28 is removable. During normal operation, the lock 3a with a key 1 1 a to use.

FIG. 6 shows a U-shaped bracket 23 mounted on a front fork 22 of a bicycle with a bracket 24 on which an anti-theft bracket 1 with an inserted pedal 10 is mounted. The U-shaped bracket 23 is on the at both

Fork tubes arranged receiving pin 19, which are provided for mounting by the brake levers 20, additionally plugged and bolted to the receiving bolt 19, each with a fixing screw which is hidden in the figure 6 on the illustrated fork side of the housing 2a and therefore not visible. Due to the mounted housing 2a, the fastening screw is not accessible and therefore not the U-shaped bracket 23

demountable.

A fixing screw 25 is screwed into the bracket 24 at the level of the receiving pin 19 and serves to align the U-shaped bracket 23 with respect to the front fork 22nd

or their two fork tubes. With a (or

a plurality of) retaining screw 26, the housing 2a screwed to the bracket 24. The retaining screw 26 thus acts with the subsequently inserted into the receiving opening 28 of the housing 2a

Lock 3a together, that the retaining screw 27 is not moved to lock the housing 2a with inserted lock 3

or can be rotated. Above the retaining screw 27, an opening 27 is inserted into the bracket 24, in which the guide portion 5 of the pedal 10 protrudes. This is

ensured that even with only one installed retaining screw 26th a lift-off of the housing 2a is not possible. The opening 28 may be covered by a cap or may be formed as an unrecognizable blind hole. In this embodiment as well, the assembled lock 3a can be removed again from the housing 2a only with a special workshop key.
