Definitions

  • the invention relates to a quick release hub for bicycles with a thief-secured by a lock and adjustable in the direction of the hub axis clamping element.
  • Quick release hubs for bicycles are known. Their purpose is to enable the wheels to be quickly removed and inserted, for example on racing bikes or mountain bikes.
  • a special closure In the known quick release hubs, a special closure is provided. This consists of a rod which projects axially through the hub body and is axially displaceable and which is provided at one end with a fixed head.
  • the actual clamping mechanism is arranged at the other end of the rod and, in a known embodiment, provides an eccentric bolt which is pivotally mounted by means of a lever and thereby axially displaces the corresponding clamping element during the pivoting movement.
  • the lever for pivoting the eccentric pin can be removed from it when not in use, and the opening of the eccentric pin provided for inserting the lever can also be optionally locked or released by means of a lock.
  • This quick release hub therefore provides for the use of a separate lever for actuating the eccentric bolt.
  • this lever can easily be lost.
  • the invention is based on the task of creating a further developed quick release hub for bicycles with an anti-theft device.
  • a threaded rod lying in the hub axis is provided, that a cylindrical clamping nut is screwed onto the end thread of the threaded rod and that a manually operable, knob-like rotating body is arranged on the clamping nut theft-proof state is freely rotatable on the clamping nut and which can be locked for the clamping state by actuating the lock in such a way that the clamping nut also rotates when the rotating body is rotated.
  • a quick release hub for bicycles with an anti-theft device designed according to this technical teaching has the advantage that not only the occasional theft is prevented, but also effective theft.
  • the basic idea of the invention is to provide a clamping nut arranged on a threaded rod as the clamping mechanism, but this clamping nut can only be rotated, ie actuated, when the ring-like rotating body arranged on the cylindrical clamping nut is brought into a fixed connection with the clamping nut has been. This can be done in that the lock creates a corresponding positive connection between the rotating body and the clamping nut, so that the rotary movement of the rotating body is transmitted to the clamping nut. In the anti-theft state, the clamping nut cannot be unscrewed by means of the rotating body.
  • the sleeve-like rotating body is freely rotatably mounted on the cylindrical clamping nut, no pliers can be attached to the rotating body, for example, in order to turn off the clamping element in the anti-theft state by force.
  • the knob-like rotating body should have a diameter such that the impeller can be securely fastened in the fork of the bicycle without great effort.
  • the rotating body can be essentially cylindrical.
  • a development of the quick release hub according to the invention suggests that the lock is arranged on or in the rotating body. This represents a technically simple way of accommodating the lock, the rotating body having enough space to be able to accommodate the lock. By actuating the lock in the rotating body, it thus comes into engagement with the cylindrical clamping nut for the clamping state of the quick-action clamping hub and thus establishes the positive connection between these two parts.
  • the rotating body completely encloses the clamping nut.
  • the complete encirclement of the clamping nut by the rotating body is to be understood to mean that the clamping nut does not have any areas which protrude beyond the rotating body and which could form a point of application for attaching pliers or the like.
  • the outer end face of the clamping nut can be seen from the outside, as long as it just ends with the end face of the rotating body or is even sunk in the rotating body, so that the already mentioned approach of pliers is prevented in all cases.
  • the clamping nut has a coaxial disk which closes one end of the rotating body facing the fork of the bicycle and which has a profile on its inside such that the lock arranged in the rotating body has a shape can be brought to an end with the profiling.
  • This represents an easy way to technical Realization of the principle of the invention is represented by the fact that the washer fixedly arranged on the clamping nut can be brought into operative connection with the rotating body when the lock is actuated accordingly and engages in the profiling of the washer.
  • the disk not only serves to receive the profiling for the positive connection between the rotating body and the disk or the clamping nut, but also serves as a cover disk for the sleeve-like rotating body. Since the profiling forms a unit with the disc, the system is very stable on the one hand, and on the other hand, this system is very easy to construct.
  • the profiling is formed by a toothed ring fixedly arranged on the inside of the disc, between the teeth of which a cam of the lock can be brought.
  • the use of a toothed lock washer with a ring gear represents a technically simple possibility to produce a positive connection between the lock of the rotating body and the washer and thus with the clamping nut.
  • the teeth of the ring gear form a large contact area on the one hand, and on the other hand the teeth are distributed over the entire circumference of the ring gear, so that a positive connection between the rotating body and the disk is possible in a large number of angular positions.
  • the cam has a semicircular profile that can be rotated about its axis.
  • the axis of rotation of this semicircular profile will thus lie on or somewhat outside the circumferential diameter of the ring gear, the semicircular cam being turned radially outwards in the anti-theft state, while in the tensioned state it is rotated inwards and reaches the area between two teeth of the ring gear. so that the positive connection is created.
  • Such a lock with a rotatable, semicircular profile-shaped cam can be implemented in a technically simple manner by modifying conventional locking cylinders.
  • the clamping nut is a T-profile nut which is pushed through from one side of the rotating body and onto which the washer is axially placed in a form-fitting manner from the other side of the rotating body.
  • the head of the T-profile nut preferably closes flush with the outer end face of the rotating body.
  • the T-profile nut has the further advantage that it forms a U-profile with its head for receiving the freely rotatable rotating body. Furthermore, due to the bracing with the fork in cooperation with the disk, it forms a securing of the lock body from the fork side with respect to a lifting off of the lock body from this side.
  • a further development of the quick release hub according to the invention proposes that a freely rotatable sleeve is arranged in the area between the tensioning element and the fork of the bicycle. Since, due to the design of the steerer tube, it will often not be possible for the rotating body to reach all the way to the fork, a corresponding distance range must be bridged. However, since a freely rotatable sleeve is arranged, no pliers can be used to forcefully unscrew the quick-release mechanism.
  • the quick-release hub has a fixed clamping bolt at the other end of the threaded rod, on which a ring is freely rotatably mounted.
  • This freely rotatable ring also prevents pliers from being attached with the purpose of unscrewing the clamping bolt.
  • the ring completely encompasses the clamping bolt, so that there are no protrusions in the sense of the above explanations that could be turned off.

  • a clamping bolt 4 in the form of a T-profile nut is firmly screwed onto the thread 3 on the right-hand side of the threaded rod 2. Instead, it is also conceivable to connect this clamping bolt 4 to the threaded rod 2, for example by welding or gluing. A fixed arrangement of the clamping bolt 4 on the threaded rod 2 is required. However, screwing on the threaded bolt 4 may make the overall assembly easier.
  • a spacer 5 attached to the threaded rod 2 connects to the clamping bolt 4. This spacer 5 forms with the T-profile of the clamping bolt 4 a U-profile in which a correspondingly formed ring 6 is freely rotatable.
  • the other side of the threaded rod 2 has the actual clamping mechanism of the quick release hub.
  • the corresponding clamping element 7 initially has a clamping nut 8, also in the form of a T-profile nut, which is screwed onto the corresponding thread 3 of the threaded rod 2.

While the disk 10 has an opening corresponding to the diameter of the threaded rod 2, the corresponding disk of the toothed ring 11 has an opening with an essentially square cross-sectional profile. This cross-sectional profile corresponds to a corresponding extension 13 of the clamping nut 8, so that when the unit consisting of the washer 10, the ring gear 11 and the spacer 12 is plugged onto the extension 13 of the clamping nut 8, a positive connection upon a rotational movement of the clamping nut 8 is created.
