Definitions
- the invention relates to a device for lifting and lowering the saddle of a bicycle with a gas spring and an actuating device, the gas spring being arranged at least partially within a frame tube of the bicycle and a cylinder-piston arrangement with an end, the cylinder or the piston has assigned trigger, the cylinder or the piston being assigned to the frame tube or the saddle and the actuating device comprising an actuating element acting directly on the trigger.
- the bicycle was optimized for different purposes, for example also from an ergonomic point of view. It has been found that the bicycle is to be dimensioned or adapted to the rider in such a way that the cyclist can extend his leg into the lowest position of the pedal while driving, namely that in the lowest position of the pedal the cyclist's leg is at least in largely stretched state.
- the wheels and frame are to be dimensioned accordingly and the saddle is to be fixed accordingly via the linkage carrying the saddle.
- the device known from DE 44 01 980 A1 for lifting and lowering the saddle of a bicycle has a gas spring and an actuating device which can be operated from the bicycle handlebar.
- the gas spring is at least partially arranged within a frame tube of the bicycle and has a cylinder-piston arrangement with an end-side trigger assigned to the cylinder.
- the piston is assigned to the frame tube.
- the actuating device has an actuating element which acts directly on the trigger.
- the actuating element essentially consists of a lever which is movable over the actuating device and rotatable about an axis which is stationary relative to the cylinder and which presses directly on the trigger of the gas spring when the actuating device is operated.
- the actuating member is designed in such a way that usually only two operating states can be reached, namely the undeployed state, in which the device is locked and the triggered state, in which the piston can essentially move freely into or out of the cylinder.
- the undeployed state in which the device is locked
- the triggered state in which the piston can essentially move freely into or out of the cylinder.
- Such an exact setting requires at known device usually a multiple attempt, the saddle must be raised and lowered several times until the saddle is at the desired height.
- Such a complicated and usually lengthy adjustment procedure considerably reduces the basic advantages of such a device for lifting and lowering the saddle of a bicycle.
- the present invention is therefore based on the object of designing and developing a device for lifting and lowering the saddle of a bicycle of the type mentioned at the outset in such a way that a more convenient and more precisely adjustable height adjustment of the saddle is made possible with a structurally simple design.
- a device of the type mentioned - conventional - is characterized in that the actuating member is designed as a force and / or path-reducing or translating lever arrangement and that one of the levers - the trigger lever - presses directly on the trigger.
- the triggering is to be avoided by means of a simple lever and instead the actuating member is to be designed in such a way that there is a force and / or displacement under or translation.
- a specific lever arrangement is provided, one of the levers - the trigger lever - pressing directly on the trigger.
- the actuation of the trigger can be metered due to the lever arrangement, so that regulation of the gas spring speed on the one hand and the extension position on the other hand is possible with the lowest possible triggering forces of the gas spring.
- the device according to the invention realizes a device in which a more convenient and more precisely adjustable height adjustment of the saddle is made possible with a structurally simple design.
- the gas spring could be adjustable and / or limited with regard to its maximum lifting height.
- a mechanical stop on the device that can be adjusted to the height of the driver would be conceivable.
- the lever arrangement could include an adjusting mechanism.
- the lever arrangement could comprise an eccentric, a cam or cam or a gear or even a gear.
- the lever arrangement for the transmission or transmission can be designed as desired, the main issue here being that the triggering forces are reduced.
- the release lever could be pivoted at one end about a fixed axis of rotation and at the other end could be pivotally connected to a second lever - connecting lever - at the end thereof.
- the connecting lever could in turn be pivotally connected at its other end to a third lever - actuating lever - the actuating lever in turn being articulated at one end about a fixed axis of rotation and being operatively connected at its other end to the actuating device.
- three levers are provided within the scope of such a configuration, which, with the corresponding ratio of the lever sections on the one hand of the release lever and on the other hand of the actuation lever, promote a reduction in the release force.
- the ratio of the lever sections on the one hand of the release lever between the fixed axis of rotation and the trigger and between the trigger and the pivot connection to the connecting lever and on the other hand the actuating lever between the fixed axis of rotation and the pivot connection with the connecting lever and between the pivot connection with the connecting lever and the free end or operative connection with the actuating device specify the degree of reduction or reduction.
- the actuating member could be of flat construction in a flange construction and also have flat means for fastening to any part.
- the actuating member could be aligned with the gas spring in a specific arrangement and / or arranged in a frame adjoining the trigger.
- the frame could comprise a total of four frame pillars, which preferably end freely at the ends, for receiving the fixed axes of rotation in pairs.
- the frame could be assigned to the cylinder or the piston. In any case, the frame must be connected to that element of the gas spring - the cylinder or the piston - which has the trigger.
- the frame could be screwed to the cylinder or the piston.
- the gas spring could be connected to a receiving element for the saddle.
- the receiving element extends, so to speak, between the element of the gas spring not assigned to the frame - the cylinder or the piston - and the saddle.
- a screw connection between the gas spring and the receiving element would also be conceivable here. This would result in a screw connection essentially between the receiving element and the piston or the cylinder.
- the receiving element could be tubular.
- the receiving element could accommodate part of the gas spring - for example the cylinder.
- a possible screw connection between the receiving element and gas spring could then also be implemented within the tubular receiving element.
- the outer surface of the receiving element could be round.
- the receiving element could also be polygonal at least at the end facing away from the saddle.
- the gas spring, the frame and possibly the receiving element could be at least partially arranged in a tubular housing. It would also be advantageous if the housing were a round tube, since in this case the device would be very easily positioned in the frame tube of the bicycle. If necessary, however, a configuration of the housing as a polygonal tube would also be conceivable. If a housing designed in this way as a polygonal tube cooperates with a frame tube which is also designed as a polygonal tube, securing against rotation of the housing relative to the frame tube would be ensured.
- the housing could be assigned to the part of the gas spring assigned to the frame tube - the cylinder or the piston.
- the housing could be assigned to the frame.
- the housing would then form the connecting link between the gas spring and the frame tube.
- the housing could be fixed in a practical manner on the frame tube and / or, if necessary, pushed into it until a collar of the housing stops on the frame tube. This would ensure a particularly simple arrangement of the device on the bicycle, also with regard to the possibility of retrofitting the device on conventional bicycles.
- the housing could either be clamped or screwed to the frame tube.
- a further simple connection possibility between the housing and the frame tube could be realized in that the housing has an external thread and the frame tube has an internal thread.
- a counter screw could be assigned to the external thread of the housing.
- the housing With regard to securing against rotation between the receiving element of the saddle and the housing connected to the frame tube, the housing could be polygonal on its inside in order to prevent engagement with the polygonal receiving element, which may be complementary, in a complementary manner guarantee.
- a latching connection between the housing and the receiving element or a configuration of the housing or the receiving element would also be conceivable such that the housing or the receiving element has a groove or an engagement element for engaging against rotation.
- the housing could be closed off at the free end of the frame with a cover.
- the actuating device acts - directly or indirectly - on the trigger via the actuating member.
- the actuating device could act on the actuating element electrically, preferably via a miniaturized servomotor or stepper motor.
- the actuating device could act inductively on the actuating member.
- the actuating device could act on the actuating member via a magnet — electrically operated lifting or pressure magnet. It would also be conceivable, within the scope of a further configuration option, for the actuating device to act hydraulically or pneumatically on the actuating member.
- an adjustment device for the length of the Bowden cable could be assigned to the housing.
- the adjusting device could be arranged in a practical manner in the area where the Bowden cable exits the housing.
- the one-piece device could be arranged in the region of the collar of the housing.
- the adjusting device could simply protrude from the collar and in the further course essentially parallel to the saddle and then essentially perpendicular to the direction of movement of the cylinder-piston arrangement his.
- the adjusting device could have a passage with an internal thread in a structurally simple manner for a hollow adjusting screw receiving at least the pulling wire of the Bowden cable.
- the internal thread could be arranged essentially parallel to the direction of movement of the cylinder-piston arrangement. In other words, the internal thread could extend in the pulling direction of the pull wire.
- the actuating device could comprise a lever, button or the like, the actuating device in the case of the provision of a Bowden cable having a lever receiving the Bowden cable at the end.
- the lever, button or the like could be assigned to the handlebar of the bicycle.
- the device In contrast to the previously proposed manual actuation of the device for lifting and lowering the saddle of a bicycle, it would be particularly advantageous and from the point of view of extremely comfortable cycling if the device would work automatically. It would be of further advantage if the device were to operate in a speed-dependent manner, so that the saddle is raised when a predeterminable speed is exceeded and is lowered when the speed falls below a predefinable speed. To this extent, the saddle is raised - automatically - when a certain speed is reached.
- a time delay could also be provided, so that if the speed falls below a certain speed, for example only briefly, the bicycle saddle is not immediately lowered due to a special traffic situation.
- the automatic device could also be combined with manual actuation, so that despite reaching a predeterminable speed, a manual unlocking is required before the saddle rises into the actual driving position.
