Definitions

  • the invention relates to a removable clamping lever. Furthermore, the invention relates to a multifunction tool. Furthermore, the invention relates to a bicycle seat post clamping device. The invention also relates to a bicycle seat post fixing arrangement. Furthermore, the invention relates to a Ko plettsystem.
  • a steel tie rod with a diameter of about 5 mm leading through the hollow hub axle of a wheel is used as the clamping axle, which exerts an axial clamping force on the outer surfaces of a dropout of a bicycle frame or a bicycle fork. This clamping force leads to a sufficient locking of the hub axle in the frame or the fork of a bicycle.
  • a quick release usually works with an eccentric, which is actuated by a small hand lever.
  • the high tensile stress causes correspondingly high frictional forces, so that the lever does not come loose by itself.
  • the eccentric is swiveled a little beyond the maximum deflection, the eccentric dead center, before it rests against the frame or the fork, so that it is fixed in the closed position by the tensile stress of the clamping axle.
  • the lock nut of the quick release can be adjusted by hand when open to preset the entire device so that there is sufficient tension at the end of the lever travel.
  • the lever of the quick release is opened, which sometimes requires a lot of force. Then usually the nut opposite the lever must be held and the lever with the swing the quick-release axle around a few turns counterclockwise so that the wheel can be lifted out of the dropout.
  • the lever is swung clockwise after the wheel is installed. The correct pre-adjustment is achieved when the lever can then be rotated without any effort until it is at an angle of 90 degrees to the plane of the impeller. Finally, forcefully wrap it all the way around until it lies as flat as possible against the frame or fork.
  • the lever should be pointing backwards so that it does not come loose unnoticed if you hit an obstacle with your bike and so that no cords, lines, wires or even items of clothing are swept away in heavy traffic. Difficulties can therefore arise during handling, whether it is that a lever has been tightened too much and is difficult to loosen, or that the clamping force has been selected too low and the impeller is not securely fixed, or that the position of the lever has changed incorrectly selected, which is associated with the described dangers.
  • quick-release axles are used for wheels these days, which have a very high level of stability and can be easily detached and fixed using a small tool.
  • This tool is preferably designed as a hexagon socket.
  • the task is therefore to provide functional elements on the bicycle that are easy to handle, with which adjustment, maintenance and repair work can be carried out more effectively and with less effort than is possible with conventional means, even during a ride.
  • the removable two-wheeler clamping lever or bicycle part clamping lever according to the invention also referred to as “clamping lever” for short in the context of the present invention, has a ratchet function for freely selectable positioning of the lever position of the clamping lever.
  • a ratchet also known as a ratchet, includes a screwing tool that, in contrast to a conventional wrench, does not have to be used again and again if there is not enough space to complete a complete turn with the key put on. Instead, to incrementally tighten or loosen a bolted joint, the ratchet is repeatedly moved back and forth through a specified angle. The ratchet transmits manual force in one direction of rotation directly to the tools to be rotated.
  • the ratchet function makes it easier to define or dose a tensile stress through the clamping lever, so that fixing and loosening assemblies on a bicycle is easier compared to using conventional quick-release skewers and the fixation is more reliable than with a quick-release skewer .
  • the clamping lever according to the invention is also advantageously designed to be removable, ie it can be detached from a fixed assembly, so that one and the same clamping lever can be used on different assemblies of the bicycle, which means that resources can be saved.
  • a bicycle seat post clamp for example, can be tightened with the clamping lever, then the clamping lever can be released from the fixed bicycle seat post clamp and used, for example, to loosen or fix wheels with thru axles to the dropouts of a bicycle frame or a bicycle fork can be used.
  • the clamping lever In order to fix the clamping lever while driving, it preferably has a plug-in safety device or at least a part of such a plug-in safety device.
  • the insertion lock can include a projection or bulge on the clamping lever, which corresponds to a complementary element on the part to which the clamping lever is to be fixed, for example the bicycle seat post clamp or the through axles (at the dropouts) of a bicycle.
  • the plug-in safeguard can also comprise an elastic material, for example, so that an insertion process in which the elastic material is compressed is possible.
  • the plug-in protection could also be implemented using a magnet that is attached to the bicycle seat post clamp or the quick-release axles.
  • the plug-in safeguard preferably has an O-ring made of elastic material, which is arranged between an annular recess on the tensioning lever and an annular recess on the component to which the tensioning lever is fixed.
  • the O-ring can be part of the clamping lever, for example. Alternatively, however, it can also be part of the component to which the clamping lever is to be fixed. Several securing elements, preferably at least some O-rings, can also be arranged on the tensioning lever and/or on the corresponding component to which the tensioning lever is fixed.
  • the clamping lever is protected against falling out as a result of vibrations, in particular during a bicycle ride, and can thus be carried directly on the bicycle without the need for additional holders or bags.
  • the multifunction tool according to the invention which can also be referred to as a two-wheeler multifunction tool, in particular a bicycle multifunction tool, has the clamping lever according to the invention or a clamping lever with a toothing function for freely selectable positioning of the lever position of the clamping lever.
  • a toothing can usually be loosened by pulling a toothing on the head of the lever of the drive axle or the tool holder and the lever position can be freely selected in relation to the rest. In this way, a desired end position of the clamping lever on the bicycle can be defined in particular.
  • clamping lever can be used for other tool functions. These functions are achieved through a modular structure of the multifunction tool. This means that at least one additional tool element can be connected to the clamping lever in order to perform an additional tool function in addition to the clamping function. In addition to the advantageous possible uses already mentioned, additional maintenance tasks can advantageously be carried out or repair processes can be implemented.
  • the bicycle seat post clamping device has a bicycle seat post clamp and a carrier for storing bicycle tools, which is designed to be mountable on the bicycle seat post clamp.
  • the bicycle seat post clamp is primarily used to fix and release a vertical position of a bicycle saddle, which is achieved in that a seat post attached to the bicycle saddle is clamped to a seat tube of a bicycle frame using the bicycle seat post clamp.
  • Additional tools, preferably bit tools, are advantageously stored on the bicycle support clamp by means of the carrier.
  • Such a bit tool also referred to as a bit insert, includes, for example, an exchangeable screwdriver blade without a handle for a specific screw head profile.
  • the mostly hexagonal holder is shaped in such a way that the bit tool can be inserted into a correspondingly standardized bit holder.

  • the bit holder can be a fixed part of the drive or comprise a separate part that can be combined with the drive.
  • components for fixing the bicycle seat post clamping device in the released state of the bicycle seat post clamping device can also be used to perform a tool function, whereby the number of parts used for the dual function can be kept low.
  • the bicycle seat post fixing arrangement according to the invention which in addition to the bicycle seat post clamping device preferably according to the invention already mentioned also has a multifunction tool according to the invention.
  • the multifunction tool according to the invention in addition to the clamping lever function for fixing and releasing numerous assemblies, such as the bicycle seat post clamping device, also has tool functions which, in particular, interact with tools, in particular bit tools, which are kept ready by the carrier for storing bicycle tools become, can be realised.
  • the complete clamping lever and multifunction tool system according to the invention also referred to as “complete system” for short within the scope of the invention, has at least one removable clamping lever according to the invention, a multifunction tool according to the invention and a bicycle seat post fixing arrangement according to the invention.
  • the at least one removable clamping lever is designed to release or fix a wheel with a quick-release axle on a dropout of a bicycle frame or a bicycle fork.
  • the removable clamping lever is preferably designed in such a way that it can be fixed to the respective dropout when the impeller is fixed to the quick-release axle and can be carried there during a journey.
  • the removable clamping lever in the complete system according to the invention can be used to loosen and in particular to permanently fix wheels with a quick-release axle. Wheels are often mounted on thru axles that are inserted through the wheel hubs of the wheels.
  • the removable clamping lever can be used to advantage for loosening and fixing the quick-release axles and can thus replace a tool that has to be carried along for this purpose.
  • the complete system according to the invention has a large number of double and multiple functions for individual components, which saves tools to carry and increases the number of maintenance and repair options during a bike ride.
  • the removable tensioning lever according to the invention preferably comprises a connecting element via which the ratchet function for fixing and/or releasing one of the following functional units can be transmitted:
  • the clamping lever preferably being designed in such a way that it can be fixed on the respective dropout on the quick-release axle when the wheel is fixed,
  • the aforementioned connecting element of the clamping lever according to the invention is preferably designed in such a way that, after a functional unit has been fixed, it can be detached from the functional unit in such a way that the fixing of the functional unit is retained.
  • the clamping lever can be used one after the other for processing different functional units. For example, a seat post can first be adjusted and fixed. The clamping lever is then released from the seat post, whereby the seat post remains fixed, and is used to release or fix a wheel. In this way, the clamping lever has multifunctional properties for both loosening and fixing components. As already mentioned, wheels are often mounted with thru axles. The removable clamping lever can be used to advantage for loosening and fixing the quick-release axles and can thus replace a tool that has to be carried along for this purpose.
  • the connecting element of the clamping lever according to the invention is very particularly preferably designed as a pin-like connecting element, preferably as a hexagon.

  • the connecting bolt is first inserted through a recess in a clamping jaw on this side of the bicycle seat post clamp.
  • the counter element is inserted from the opposite side through a recess of a clamping jaw on the other side of the bicycle seat post clamp. If the connecting bolt is screwed tight in the counter element, the bicycle seat post clamp fixes a bicycle seat post in a seat tube of a bicycle frame.
  • the connecting bolt can, in addition to a receptacle for the already mentioned pin-like connecting element, also have an annular projection which is preferably set back somewhat from the end and which has a larger diameter than the recesses of the clamp and so when the bicycle seat post clamp is screwed tight Apply pressure to the jaw facing you to tighten the bicycle seat post clamp around the seat tube.
