Description

Device for stationary bicycle training

The invention relates to a device for stationary bicycle training, having a support on which a smart trainer can be positioned, on which a rear axle of a bicycle can be rotatably mounted.

Smart trainers are known as training tools for stationary bike training. It is usually provided that a rear axle of a bicycle can be rotatably mounted on the smart trainer, the smart trainer usually having a braking device which applies a, usually adjustable, braking force to rotation of the rear axle. In this way, normal cycling training on a road can be simulated. The braking device is usually designed to apply a resistance that brakes the rotational movement directly to the rotatable rear axle or indirectly to a wheel of the bicycle that rotates with the rear axle.

This is where the invention comes into play. The object of the invention is to provide a device of the type mentioned at the outset, which enables an optimized simulation of bicycle training.

The object is achieved according to the invention in that, in a device of the type mentioned at the outset, a base element which can be positioned on a surface is provided, with which the support is connected via at least one spring element so that it can be moved, in particular tilted about a longitudinal axis.

The basis of the invention is the idea of using the device for stationary bicycle training to realistically simulate bicycle training carried out on a road.

Riding a bicycle usually involves tilting movements of the bicycle relative to the surface of the bicycle. Because movements, in particular tilting movements, of a bicycle mounted on a smart trainer can be carried out practicably during stationary bicycle training with the device, a realistic driving experience for a user and a reduction in tension within the framework of the vehicle can be made possible. By connecting the support to the base element via at least one spring element, a movement, in particular a tilting movement, of the support relative to the base element can be implemented in a simple manner. Typically, the at least one spring element is arranged, in particular between the support and the base element, in such a way that a movement, in particular tilting, of the support relative to the base element against a spring force of the spring element is possible. Several such spring elements can expediently be provided. The spring elements can be designed differently or the same.

It is practical if the tilting movement can be carried out around a longitudinal axis. The tilting then usually takes place orthogonally to the longitudinal axis. The longitudinal axis is generally oriented parallel to a longitudinal direction of the device, in particular the longitudinal direction of the support. The longitudinal axis can be a longitudinal axis of the device. Usually, the longitudinal axis is parallel to the longitudinal direction of a bicycle arranged on the support or the smart trainer when used as intended. The at least one spring element generally has a spring, the spring being connected to the support via a first connection element and to the base element via a second connection element. The connection elements can be plate-shaped. Most of the time, the connection elements are formed with, in particular, metal. The at least one spring element or its spring is usually designed with a or as a coil spring.

It is advantageous for a realistic movement, in particular a tilting, of the support if several spring elements are provided, which are positioned symmetrically to the longitudinal axis in a top view of the support. The spring elements can be designed as described for at least one spring element. It is expedient if, in plan view, the spring elements are arranged in pairs with respect to the longitudinal axis, wherein the spring elements of a pair can be arranged essentially mirror-symmetrically to the longitudinal axis. It is favorable for high stability if, in plan view, one or more spring elements, in particular at least one pair of spring elements, are in an arrangement range of 15% to 85%, in particular 20% to 80%, preferably 25% to 75%, of an extension the support is located in the longitudinal axis direction of the longitudinal axis. There are preferably several pairs of Spring elements in the arrangement area. The described arrangement of the spring elements preferably applies in a top view.

Top view usually refers to a view from above or in a vertical direction of the device, in particular support, when the device is used as intended. The longitudinal axis is usually aligned parallel to or corresponds to the longitudinal direction of the device, in particular the support. The top view is usually a view in a direction parallel to the stacking direction, as detailed below.

It is advantageous if at least one damper element is provided, via which the support is connected to the base element. In this way, tilting mobility of the support relative to the base element can be implemented in a practical manner. As a rule, the at least one damper element is arranged between the support and the base element. In particular, the damper element can be used to dampen a tilting movement of the support relative to the base element. The damper element is usually designed as a vibration damper in order to dampen a vibration caused by the at least one spring element, in particular tilting shrinkage of the support. It is expedient if the at least one damper element causes strong damping, in particular damping in the vicinity of an aperiodic limit. The damper element may have an elastic segment to dampen the vibration. The elastic segment can be formed, in particular, from rubber. It has proven useful if the damper element has two metal connections, between which the elastic segment is arranged, one of the metal connections being connected to the base element and the other metal connection being connected to the support. The metal connections are usually formed with, in particular, metal, often an iron alloy. The damper element can be, for example, a rubber buffer. Several damper elements can expediently be provided.

It is advantageous for a high level of robustness if several damper elements are provided distributed along the longitudinal axis, which are preferably arranged symmetrically to the longitudinal axis. The longitudinal axis is preferably defined by the damper elements. In particular, the damper elements can lie essentially on the longitudinal axis. It has proven useful if at least three, especially at least four, Damper elements are provided. The damper elements are usually arranged at regular intervals from one another. The damper elements can be arranged in pairs with respect to the longitudinal axis, wherein the damper elements of a pair can be arranged essentially mirror-symmetrically to the longitudinal axis. However, it is preferred if the damper elements are arranged on a, in particular single, straight line, preferably at regular intervals from one another. The straight line preferably lies on the longitudinal axis in plan view. In particular, the longitudinal axis can be defined by connection areas at which the damper elements are connected to the support.

It is beneficial for robustness if, when viewed from above, the spring elements are at a greater distance from the longitudinal axis than the damper elements. The distance is usually measured orthogonally to the longitudinal axis. In particular if the spring elements are arranged in pairs, it is advantageous if, in plan view, the damper elements are arranged in a direction orthogonal to the longitudinal axis between the pairs of spring elements. It has proven useful if at least one pair of spring elements and one damper element are arranged in a plan view in such a way that they lie on a straight line aligned orthogonally to the longitudinal axis. Preferably, several pairs of spring elements are each arranged with a damper element in this way. It is favorable for high stability if, in plan view, at least one such arrangement of a pair of spring elements and a damper element is in an arrangement range of 15% to 85%, in particular 20% to 80%, preferably 25% to 75%, of an extent Support is located in the longitudinal axis direction of the longitudinal axis. Preferably there are several such arrangements in the arrangement area.

A robust implementation can be achieved if the support is plate-shaped. Typically, a longitudinal direction of the support is parallel to a longitudinal direction of a bicycle arranged on the support when used as intended. The support can, for example, be a plate, in particular made of wood. It is advantageous if the base element is plate-shaped. Typically, a longitudinal direction of the base element is parallel to a longitudinal direction of a bicycle arranged on the support when used as intended. The basic element can, for example, be a plate, in particular made of wood. The support and the base element are usually arranged at a distance from one another by the at least one damper element and/or the at least one spring element. It is practical if the support and the base element are arranged essentially parallel to one another, in particular if the support and the base element are plate-shaped. In particular, this can be the case for an unloaded state of the support or a non-tilted state of the support about the longitudinal axis relative to the base element.

It is advantageous if the support and the base element are arranged one above the other along a stacking direction. The stacking direction is usually oriented orthogonally to a longitudinal direction and width direction of the support or the base element. A height of the support or the basic element is usually smaller than a respective length and a respective width of the support or the basic element. The longitudinal direction, width direction and height direction are usually orthogonal to one another. It is useful if the support and the base element have the same shape and/or size. This applies in particular if the support and/or the base element are plate-shaped.

Usually, an area of the device, in particular the support, in which the smart trainer or the rear axle of the bicycle is located when the device is used as intended is referred to as the rear axle area and / or optionally an area of the device, in particular the support, in which the smart trainer or the rear axle of the bicycle is located When the device is used as intended, the front wheel bearing or front axle of the bicycle is located in a top view, referred to as the front axle area. A direction from the rear axle area to the front axle area, in particular parallel to the longitudinal axis, is usually referred to as the alignment direction.

For a robust movement, in particular a tilting movement, it is advantageous if, in plan view, a center of gravity, in particular a center of gravity and/or center of mass, of the support is located in a first half, in particular a first third, of a support extension of the support in the longitudinal axis direction of the longitudinal axis. This is particularly true when viewed from above. Usually the first half of a second half of the support extension is along the alignment direction Upstream of the longitudinal axis or the first third is upstream of a second third and this is upstream of a third third of the support in the alignment direction along the longitudinal axis.

It is advantageous for tilting stability if, in plan view, the rear axle region of the support is located in the alignment direction in a first half, in particular a first third, of a support extension of the support in the longitudinal axis direction of the longitudinal axis. Usually, the first half is arranged upstream of a second half of the support extension in the alignment direction along the longitudinal axis or the first third is arranged upstream of a second third and this is arranged upstream of a third third of the support in the alignment direction along the longitudinal axis. It is useful if the support is designed for a corresponding arrangement of the smart trainer or the rear axle of the bicycle on the first half or the first third of the support.

It is advantageous if, in plan view, a pair of spring elements, in particular designed as described, is arranged in the alignment direction on a first half, in particular a first third, of a support extension of the support in the longitudinal axis direction of the longitudinal axis. Usually, the first half is arranged upstream of a second half of the support extension in the alignment direction along the longitudinal axis or the first third is arranged upstream of a second third and this is arranged upstream of a third third of the support in the alignment direction along the longitudinal axis.

It is practical if the support has a tapering width at least in sections along the longitudinal axis, in particular in the alignment direction. It is advantageous if an average width of the first half, in particular of the first third, of the edition is greater than an average width of the second half, in particular of the third third, of the edition. The width is usually measured in plan view orthogonal to the longitudinal axis. In a top view of the support, the support can expediently have a substantially drop-like shape or a substantially trapezoidal shape, in particular according to a, preferably isosceles, trapezoid. Typically, the longitudinal axis in a plan view of the support forms an axis of symmetry of the support.

For practical application, it is advantageous if the support has a shape in plan view, which can be formed along the longitudinal axis by several partial segments, wherein a first sub-segment has a trapezoidal shape and a second sub-segment has a rectangular shape or trapezoidal shape, the first sub-segment being connected on a longer base side of its trapezoidal shape to the second sub-segment, preferably a longer side of its rectangular shape or longer base of its trapezoidal shape. It is preferred if a third sub-segment has a trapezoidal shape and the second sub-segment has a rectangular shape, the second sub-segment being arranged between the first sub-segment and the third sub-segment, so that in each case a longer base side has a trapezoidal shape with opposite sides, in particular longer sides , the rectangular shape of the second sub-segment are connected. In particular, the second sub-segment can have a square shape. The aforementioned trapezoidal shapes usually have two mutually parallel base sides, which are connected by two mutually non-parallel leg sides. In plan view, the longitudinal axis preferably represents an axis of symmetry, in particular a mirror symmetry axis, for the shape of the support. The aforementioned shape applies in particular if the support is plate-shaped. The basic element can be designed in a manner analogous to that stated above. It is preferred if the rear axle region of the support is arranged in the first segment and/or second sub-segment. The front axle area is preferably arranged in the third sub-segment. This has proven to be advantageous for robust and comfortable tilting of the support. It is advantageous if a pair of spring elements, in particular designed as described, is arranged on the first sub-segment and/or second sub-segment.

It has proven useful if there is a blocking device with which movement, in particular tilting, of the support relative to the base element can be blocked. Depending on the training objective, this can prevent the support from moving or tilting. The blocking device can, for example, have one or more movable blocking bodies, which can be arranged, in particular reversibly, between the support and the base element, so that the mobility or tiltability of the support is blocked. For this purpose, the blocking device can expediently have a control, which can in particular be designed mechanically, electrically, hydraulically and/or pneumatically. For example, with the control, the blocking body can be arranged between the support and the base element as stated. It is advantageous if a preload of the at least one spring element can be adjusted. As a result, the mobility, in particular tiltability, can be adjusted depending on the application conditions, for example depending on the weight of a user. It is practical if preloads of different spring elements can be adjusted differently. It can be advantageous if the preloads of several, in particular all, spring elements can be adjusted at the same time. A preload control device, in particular mechanical, electrical, hydraulic and/or pneumatic, can expediently be present, with which the preload(s) can be adjusted, in particular in the aforementioned manner.

It is advantageous if the at least one spring element has a progressive spring characteristic. This usually results in a restoring force of the spring element that increases disproportionately with the deflection of the spring element. This is favorable for a comfortable deflection of the support for a user. It is practical if the at least one spring element is formed with a helical spring, in particular with a conical spring design, and/or a mixed circuit of several springs. The mixing circuit can have a plurality of springs, in particular coil springs, connected in parallel and/or in series. The springs of the mixing circuit are usually connected to the support via a common first connection element and to the base element via a common second connection element. The connection elements can be plate-shaped. Most of the time, the connection elements are formed with, in particular, metal.

It is advantageous if several spring elements, which connect the support and base element, have spring element axes with axial directions which are orthogonal to the longitudinal axis and have an angle of 0.5° to 45° to an imaginary vertical plane in which the longitudinal axis lies. In particular, the angle can be between 1° and 30°, preferably between 1° and 5°. The vertical plane is preferably a plane of symmetry of the device, in particular of the support. It has proven useful if at least one such spring element is arranged on both sides of the vertical plane. Spring elements are preferably arranged in pairs on both sides of the vertical plane in such a way that the axial directions of the spring element axes of spring elements of a pair are preferably the same Have angles. Preferably, the spring element axes of spring elements of a pair have axial directions which are not aligned parallel to one another, in particular mirror-symmetrically, to the vertical plane. In particular, the spring element axes are aligned mirror-symmetrically to the vertical plane. Usually, ends of the spring elements of the pair connected to the base element are further spaced apart than ends of the spring elements associated with the support. It has proven useful if at least two pairs of the aforementioned spring elements are provided.

For a simple implementation, it is expedient if several spring elements, which connect the support and the base element, have spring element axes with axial directions which are orthogonal to the longitudinal axis and parallel to an imaginary vertical plane in which the longitudinal axis lies. The vertical plane is preferably a plane of symmetry of the device, in particular of the support. It has proven useful if at least one such spring element is arranged on both sides of the vertical plane. Spring elements are preferably arranged in pairs on both sides of the vertical plane in such a way that the axial directions of the spring element axes of spring elements of a pair preferably have the same angles. Preferably, the spring element axes of a pair of spring elements are aligned mirror-symmetrically to the vertical plane. It has proven useful if at least two pairs of such spring elements are provided. Spring elements aligned both parallel and, as stated above, at an angle to the vertical planes can be provided. The alignments of the spring element axes then relate to the same vertical plane.

It is advantageous if there are one or more stop elements which limit movement, in particular tilting, of the support relative to the base element. The stop element can be arranged in a fixed position relative to the base element or the support. The stop element can be arranged between the support and the base element. It is practical if the stop element has an elastic stop section, which can be formed with rubber, for example, in order to use the stop section to dampen a shock between the support and the base element. Appropriately, several stop elements can be arranged on both sides of the longitudinal axis, especially in plan view. It is beneficial if there is one on both sides imaginary vertical plane, in which a longitudinal axis of the device lies, two stop elements are arranged, which limit movement, in particular tilting, of the support relative to the base element. The stop elements can be arranged mirror-symmetrically to the vertical plane.

It is practical if the at least one spring element is detachably arranged in the device. As a result, the spring element can be easily replaced, for example by a spring element with a different spring characteristic.

It has been shown that, compared to classic bicycle training on a road, stationary bicycle training often results in greater instability in the area of a zero position in relation to a tilting movement of the support or a bicycle located on the support, which is usually caused by a reduced or lack of gyroscopic effect, caused by a rotational movement of the bicycle wheels, can be explained during stationary training. For a high level of practical application, it is advantageous if a stabilization device connected to the support and the base element is provided, which has a spring and/or damper unit with a non-linear, in particular degressive, spring and/or damper characteristic curve in order to maintain the support relative to the base element to stabilize against a tilting movement around the longitudinal axis from the zero position. The zero position is usually a zero position of the edition. The zero position of the support usually refers to an alignment of the support relative to the base element without tilting the support about the longitudinal axis. In the zero position of the support, the support and the base element are usually aligned parallel to one another or the support is usually aligned horizontally. The stabilization device can expediently be connected to the support, and in particular to the base element, in such a way that the support is tilted from the zero position against a resistance force of the stabilization device. The spring characteristic curve and/or damper characteristic curve is preferably degressive with increasing deflection from the zero position. The stabilization device is usually part of the device.

It is preferred if the spring and/or damper characteristic curve of the spring and/or damper unit is symmetrical to the zero position of the support relative to the base element and is degressive, so that there is resistance to a tilting movement about the longitudinal axis increases less as the deflection increases. This makes it possible to achieve a realistic tilting behavior of the support, in particular without a sudden change in resistance.

The damper unit can be formed with an elastically and/or plastically deformable damper body in order to form the resistance when the damper body is deformed. The damper unit can have several damper bodies. The spring unit can be formed with several springs, in particular a mixed circuit of several springs. The damper body can be made of an elastic material, in particular rubber. The damper body can have a shell, in particular a deformable one, filled with a gel-like, partially liquid, liquid and/or gaseous medium. The damper body can have one or more chambers, which can be filled with the medium. The chambers can be connected to one another in a medium-conducting manner via membranes and/or openings, so that when the damper body is deformed, the medium is at least partially transferred between different chambers, in particular pressed from one chamber into another chamber, by a pressurization caused by the deformation.

The stabilization device, in particular the spring unit and/or the damper unit, is usually arranged between the support and the base element. The support is usually connected to the base element via the stabilization device, in particular the spring unit and/or the damper unit. The stabilization device can have several spring units and/or several damper units.

For a high level of robustness, it is advantageous if several damper bodies or several springs of the stabilization device are arranged between the support and the base element, which are preferably each positioned symmetrically to the longitudinal axis in a top view of the support. It is expedient if, in a top view, the damper bodies or the springs are arranged in pairs with respect to the longitudinal axis, whereby the damper bodies of a pair can be arranged essentially mirror-symmetrically to the longitudinal axis. Alternatively and/or cumulatively, it can be advantageous if one or more damper bodies are arranged on the longitudinal axis. It is advantageous if the support is designed for positive and/or non-positive connection of a smart trainer. For this purpose, the support can have a connecting device. One or more recesses can expediently be present in the support in order to insert the smart trainer, in particular in a form-fitting manner, into the recesses or in particular the connecting device has the recesses. It has proven useful if there are several essentially parallel depressions, with preferably longitudinal directions of the depressions being aligned orthogonally to the longitudinal axis. Alternatively or cumulatively, the connecting device can have a rope in order to tension the smart trainer with the rope on the support in a non-positive manner. The rope can be, for example, a cord, a cable or a band. It is advantageous if the connecting device is designed to be detachable from a support body of the support. The connecting device can then expediently have the aforementioned depressions. In this way, the support can be adapted to accommodate different smart trainers, in particular modularly, by loosening and replacing the connecting device.

Different connection devices can expediently be provided, which correspond to differently designed smart trainers, in order to connect different smart trainers to the support or the support body via the respective corresponding connection devices. The connecting device can be connectable to the support body in a form-fitting and/or force-fitting manner. A coupling device can be provided for this purpose. It is practical if the connecting device is designed with a connecting plate, the connecting plate having one or more recesses mentioned above. The coupling device can, for example, have a recess in the support for receiving the connecting device, in particular the connecting plate. A non-positive connection of the coupling device to the support can be implemented, for example, with a screw connection or clamp connection.

It has proven useful if the device has a front wheel bearing for supporting a front wheel of a bicycle, which bicycle is connected via a rear axle to a smart trainer positioned as intended on the device. The front wheel bearing can be plate-shaped. The front wheel bearing can have a recess for receiving the front wheel, in particular in a form-fitting manner. The Front wheel bearing can be implemented, in particular designed and/or aligned, in a manner analogous to that described for the support.

It is expedient if the front wheel bearing can be moved, in particular tilted, and connected to a surface via at least one spring element. It is practical if the front wheel bearing is connected to the base element in a movable, in particular tiltable manner, via at least one spring element. The front wheel bearing can be tiltable with the at least one spring element about a longitudinal axis, in particular the aforementioned longitudinal axis. The front wheel bearing can expediently be connected to the base element via one or more damper elements. The connection of the front wheel bearing to the base element can be implemented in a manner analogous to that of the support, in particular with a corresponding arrangement or alignment of spring elements and/or damper elements.

The support and front wheel bearings can be designed separately from one another, in particular with separate plates. The front wheel bearing can be movable relative to the support. It has proven useful if the front wheel bearing is made in one piece with the support. The front wheel bearing can expediently be designed as part of the support. The support and front wheel bearing can thus be implemented with a single plate, which is connected to the base element via the at least one spring element in a movable manner, in particular tiltable about the longitudinal axis. The longitudinal axis is usually oriented in the longitudinal direction of the support.

It is expedient if the base element is designed with a plate. In plan view, the base element, in particular its plate, can have essentially the same shape and/or size, in particular longitudinal extent and width extent, as the support, in particular its plate.

It is advantageous if a smart trainer, on which a rear axle of a bicycle can be rotatably mounted, is connected to the support, in particular in a detachable manner. As stated above, this allows an optimized simulation of bicycle training to be implemented by properly storing a bicycle on the Smart Trainer. Accordingly, it is advantageous if a bicycle is connected to the Smart Trainer, with a rear axle of the bicycle being mounted on the Smart Trainer in order to be able to communicate with the Smart Trainer. Trainer to apply a braking force or resistance against a user's intended pedaling movement on the bicycle. Smart trainer and possibly bicycle can be part of the device for stationary bicycle training. Although an implementation with a smart trainer is preferred, a bicycle ergometer, in particular a rear area of the bicycle ergometer, with the support, in particular releasably, can be used in an analogous manner instead of the smart trainer or instead of the smart trainer with the rear axle of a bicycle mounted on it , be connected. This means that an optimized simulation of bicycle training can be implemented with the bicycle ergometer, in particular analogous to the smart trainer with the rear axle of the bicycle mounted on it. Accordingly, it is advantageous if the device, in particular the support, is designed for the positive and/or non-positive connection of a bicycle ergometer. For this purpose, the connection device can be designed accordingly, in particular in a manner analogous to that for connecting to the smart trainer. The bicycle ergometer can be part of the device for stationary bicycle training, in particular instead of the smart trainer and possibly bicycle. A rear axle area of the bicycle corresponds to a rear area of the bicycle ergometer and a front axle or a front wheel of the bicycle corresponds to a front area of the bicycle ergometer.

Further features, advantages and effects of the invention result from the following illustration of an exemplary embodiment. The drawings to which reference is made show:

1 is a perspective view of a device for stationary bicycle training, on which a smart trainer and a bicycle are arranged;

Fig. 2 shows the device for stationary bicycle training from Fig. 1;

Fig. 3 shows the device for stationary bicycle training without a support in a top view; 4 to 6 show the device of FIG. 1 in a non-tilted state and in tilted states.

Fig. 1 shows a schematic representation of a device 1 for stationary bicycle training in a perspective view. The device 1 is formed with a plate-shaped support 6 and a plate-shaped base element 7, the support 6 and base element 7 having at least one spring element 8 relative to one another movable, in particular tiltable, are connected. The at least one spring element 8 is arranged between the support 6 and the base element 7. The base element 7 can have, at least in sections, an anti-slip coating, for example a rubber coating, on its underside for resting on a surface. The support 6 and the base element 7 are each formed with, in particular, a plate. The support 6 and the base element 7 are arranged one above the other at a distance from one another in a stacking direction essentially orthogonal to a longitudinal direction and width direction of the support 6 or the base element 7. The longitudinal direction and width direction are aligned orthogonally to each other and each orthogonally to a height direction of the respective plate. A longitudinal extent in the longitudinal direction and a width extent in the width direction are generally designed to be greater than a height in the height direction of the respective plate. The height direction is usually essentially parallel to the stacking direction.

A smart trainer 2 and in particular a bicycle 3 can be positioned on the support 6 as shown in FIG. 1. A rear axle 4 of the bicycle 3 can be rotatably mounted on the smart trainer 2. With the Smart Trainer 2, when used as intended by a user, a braking force can be applied to the rear axle 4, which is driven by the user by pedaling. The smart trainer 2 and possibly the bicycle 3 can be part of the device 1 for stationary bicycle training. In an analogous manner, instead of the smart trainer 2 and bicycle 3, a bicycle ergometer can be positioned on the support 6 or connected to it.

The support 6 has a connecting device formed with recesses 10 for a positive connection of the smart trainer 2 to the support 6. For this purpose, for example, two recesses 10 oriented parallel to one another can be present in the support 6 in order to positively insert the legs of the smart trainer 2 into the recesses 10, for example shown in Fig. 2. In addition, a connecting means, in particular as part of the connecting device, for a Non-positive connection of the smart trainer 2 to the support 6 may be provided, for example one or more tension straps, in order to tension the smart trainer 2 to the support 6. The support 6 and the base element 7 are connected to one another so that they can be tilted relative to one another about a longitudinal axis L. The longitudinal axis L is usually oriented parallel to a longitudinal direction of the device 1, in particular support 6. It is useful if the support 6 and the base element 7 have the same shape and/or size. In plan view, the longitudinal axis L preferably represents an axis of symmetry, in particular a mirror axis of symmetry for the shape of the support 6 and/or shape of the base element 7. The longitudinal axis L is usually essentially parallel to a longitudinal axis L of the bicycle 3, the rear axle 4 of which, when used as intended, is on the bicycle Smart Trainer 2 is stored.

A front wheel bearing 11 can expediently be provided for supporting a front wheel of the bicycle 3, which bicycle 3 is connected via a rear axle 4 to a smart trainer 2 positioned as intended on the device 1. The front wheel bearing 11 can be implemented with the support 6, for example formed by a section of the support 6 on which the front wheel can be stored. The support 6 can have a recess to accommodate the front wheel with the recess. Preferably, the support 6 is in plan view for an arrangement of the smart trainer 2 or the rear axle 4 of the bicycle 3 on a first half of an extension of the support 6 in the longitudinal axis direction of the longitudinal axis L and for an arrangement of a front axle 5 or a front wheel of the bicycle 3 formed on a second half of the extent of the support 6 in the longitudinal axis direction of the longitudinal axis L. Usually, in an alignment direction oriented parallel to the longitudinal axis L from the rear axle 4 to the front axle 5, the second half is arranged downstream of the first half. Accordingly, it is advantageous if the connecting device or its recesses 10 are arranged on the first half and the front wheel bearing 11 on the second half.

Alternatively, the front wheel bearing 11 can be implemented separately from the support 6, for example with a separate plate, which is connected to the base element 7 in a movable, in particular tiltable manner. This is shown in FIG. 2 by a dashed line running orthogonally to the longitudinal axis L.

In plan view, the support 6 can expediently have a tapering width in the longitudinal axis direction of the longitudinal axis L, at least in sections. It is cheap if the support 6 has a drop-like shape, in particular a bulbous area of the drop forming a rear area of the drop, shown for example in Fig. 3. It has proven useful if the plate of the support or plate of the base element has a shape in plan view which can be formed along the longitudinal axis by a plurality of partial segments, a first partial segment having a trapezoidal shape, a second partial segment having a rectangular shape and a third partial segment having a trapezoidal shape. The second partial segment is arranged between the first partial segment and the third partial segment, so that a longer base side of the trapezoidal shape of the first and third partial segment is connected to opposite sides, in particular longer sides, of the rectangular shape of the second partial segment.

Between the support 6 and the base element 7, a plurality of damper elements 9 are arranged, which connect the support 6 and the base element 7 to one another in a movable manner, in particular in a tilting manner, about the longitudinal axis L. The damper elements 9 are usually formed with an elastic segment, usually made of rubber. With the damper elements 9, a tilting movement, in particular tilting vibration, of the support 6 can be dampened. The damper elements 9 can be designed as rubber buffers.

The damper elements 9 are arranged in a plan view along the longitudinal axis L, in particular on the longitudinal axis L, shown for example in Fig. 3. Fig. 3 shows a schematic representation of the device 1 of Fig. 1 without support 6 in a plan view or without base element 7 in a view opposite to the top view. It is advantageous if several spring elements 8 are provided. These are preferably arranged symmetrically to the longitudinal axis L in a top view. It has proven useful if, in plan view, at least one pair of spring elements 8, which spring elements 8 are arranged mirror-symmetrically to the longitudinal axis L, is located in an arrangement range of 15% to 85% of an extension of the support 6 in the longitudinal axis direction of the longitudinal axis L. It is advantageous if, in plan view, the pair of spring elements 8 and one of the damper elements 9 are arranged in such a way that the spring elements 8 of the pair and the damper element 9 are located on a straight line aligned orthogonally to the longitudinal axis L. 4 to 6 show schematic representations of the device 1 in a view along the longitudinal axis L in the alignment direction. In FIGS. 4 to 6, the longitudinal axis L is aligned orthogonally to the plane of the drawing. 4 shows the device 1 in a state without tilting of the support 6 relative to the base element 7. The support 6 and the base element 7 are then aligned essentially parallel to one another. Between the support 6 and the base element 7 are the damper elements 9 and the spring elements 8. The spring elements 8 can expediently be formed with a spring and two connecting elements, the spring being arranged between the connecting elements and one of the connecting elements with the support 6 and the other connection element is connected to the base element 7. Fig. 5 shows the device 1 in a state with a tilting of the support 6 relative to the base element 7 counterclockwise about the longitudinal axis L and Fig. 6 with a tilting of the support 6 relative to the base element 7 in a clockwise direction about the longitudinal axis L. The tilting the support 6 is connected to a corresponding compression or expansion of the spring elements 8, in particular their springs.

It is usually provided that the spring elements 8 have spring element axes F, the axial directions of the spring element axes F being aligned orthogonally to the longitudinal axis L and parallel to an imaginary vertical plane in which the longitudinal axis L lies; this is shown in FIG. 4 with dash-dotted spring element axes F shown. It is advantageous if the axial directions of the spring element axes F are orthogonal to the longitudinal axis L and are aligned at an angle of 0.5° to 45° to an imaginary vertical plane in which the longitudinal axis L lies, this is shown in dashed lines in FIG Spring element axes F 'shown. In this case, it is advantageous if spring elements 8 arranged in plan view on different sides of the longitudinal axis L have spring element axes F with axis directions aligned mirror-symmetrically to one another with respect to the longitudinal axis L.

If the device 1 for stationary bicycle training has a, in particular plate-shaped, support 6, on which a smart trainer 2 can be positioned, on which a rear axle 4 of a bicycle 3 can be rotatably mounted, and a base element 7 that can be positioned on a surface, in particular plate-shaped , whereby the support 6 and the base element 7 have at least one spring element 8 movable, in particular tiltable about a longitudinal axis L, are connected to one another, an optimized simulation of a bicycle training can be made possible. This is particularly true if, in plan view, several spring elements 8 are arranged in pairs on both sides of the longitudinal axis L and / or the spring elements 8 have spring element axes F with axial directions which are orthogonal to the longitudinal axis L and an angle of 0.5 ° to 45 ° to an imaginary one vertical plane in which the longitudinal axis L lies.
