    description
    The invention relates to a scooter with a folding steering axis according to the type specified in the preamble of claim 1 protection.
    Collapsible scooters are well known. Due to their compactness, they have become a popular form of transport. There are various ways of making the steering axle foldable, see DE 200 08 653 U1, DE 201 08 067 U1 and DE 10 2011 107 219 A1.
    In a known manner, a scooter comprises a running board and a steering axle which has a front wheel on a front fork at its lower end and a handlebar at its opposite upper end. At the rear end of the footboard, a rear wheel is mounted on a rear fork of the footboard. The footboard and the steering axle are connected via a steering axle holder. The steering axle holder has a guide tube which is used to guide the steering axle and is supported on the front fork. At the front end of the footboard, the steering axle holder is rotatably arranged on a joint, which has two tabs that are spaced apart from one another. The joint has an axis of rotation and has two positions: an unfolded, built-up operating position and a folded-up folding position. These two positions are secured by means of a locking mechanism arranged on the hinge.
    The invention is based on the object of providing a folding arrangement for a scooter that is easy to use and locks the scooter in its operating position and its folding position with greater security compared to the prior art.
    According to the invention, the scooter is designed to be foldable with a hinge for the steering axis, the hinge being designed with a locking mechanism which can be actuated exclusively via a safety device. The safety device blocks the locking mechanism in the operating position and the folding position must first be released before the locking mechanism is released. This ensures that the scooter is securely locked in its operating position and its folding position.
    In a preferred embodiment, the joint has a first part which is non-positively, positively or cohesively connected to the front region of the footboard. The first part of the joint can be connected to the footboard, for example by means of a screw or rivet connection. This has the advantage that the static first part of the joint can be made strong, so that the weight forces are distributed between the front and rear wheels.
    Preferably, the first part of the joint is designed as a housing. This gives the joint increased stability. The housing can be made of aluminum and / or plastic, which means that the weight of the scooter is low enough to be easily transportable.
    The housing has a bearing bore for receiving a further joint part.
    The steering axle holder preferably forms a second part of the joint. The steering axle holder is connected to a bearing pin which engages in the bearing bore of the first part of the joint. As a result, the housing and the steering axle holder are movably, in particular rotatably, connected to one another, as a result of which the scooter can be folded.
    According to a further embodiment, the housing is formed by the pair of tabs and a guide wall connecting the pair of tabs. The closed shape of the housing contributes to the stability of the static part of the joint.
    The housing preferably has engagements into which the locking mechanism can engage and lock. This ensures that the scooter is secured in the upright operating position and / or in the folded and folded position of the steering axle.
    In a further embodiment, the pair of tabs of the housing defines a bottom
    gene-shaped slot. The slot can serve as a guide for the movable second part of the joint.
    Preferably, the steering axle holder is designed at its lower end in the direction of the footboard as a fork which has a connecting guide pin. The fork-shaped area of the steering axle holder surrounds the housing. A stable guidance of the steering axle holder in its rotation around the housing is thus possible.
    Preferably, the guide bolt connecting the fork of the steering axle holder passes through the arcuate slot of the housing. The slot and the guide pin together form a stable guide for the folding movement of the steering axle holder from the upright operating position to the folded folded position and vice versa.
    According to a preferred embodiment, a locking mechanism is arranged on the steering axle holder by means of which the steering axle is secured in the operating position and / or the folding position.
    The locking mechanism preferably has a rotary shaft which passes through the steering axle holder above the pair of tabs. The rotating shaft has a flange at one free end and is connected to a handle at the other free end. The locking mechanism can advantageously be actuated via the handle.
    In a preferred embodiment, a rocker element is arranged on the rotating shaft. The rocker element is designed at one end to form a holding means assigned to the safety device. At the other end, the rocker element is designed as a pawl that engages in the respective engagements of the housing in the operating position and in the folding position. This ensures the respective position of the steering axle holder.
    In a further embodiment, the rocker element is combined with a spring. The restoring force of the pretensioned spring presses the pawl in the direction of engagement in the housing. The pawl of the rocker element remains in a locked position and ensures the safe position of the steering axis in the respective folding or operating position.
    According to a further embodiment, a securing device is arranged on the steering axle holder, which has a displacement element. In the starting position, the displacement element blocks the retaining means of the rocker element and thus ensures that the pawl of the rocker element is clamped in the engagement of the housing so that it cannot slip. By releasing the sliding element, there is room for the holding means. It is thus possible to release the pawl of the rocker element from the respective engagement using the handle of the locking mechanism. The released pawl can thus slide over the guide wall in order to lock into the respective other engagement, the displacement element returning to its starting position and the holding means of the rocker element being blocked again. The consequence of this is that the pawl is clamped in such a way that it cannot slip in the engagement of the housing. The blocked locking mechanism thus secures the position of the steering axle both in the folding position and in the operating position. The folding movement of the steering axle holder is only possible by first releasing the sliding element of the safety device and then releasing the pawl of the locking mechanism from its engagement. This ensures that the scooter is securely locked in the operating position and in the folded position.
    The sliding element is preferably installed with a spring. The restoring force of the spring acts in the direction of the blocking position of the rocker element. By moving the sliding element against the force of the spring, there is room for the holding means of the rocker element. This in turn enables the pawl to be released from the engagement of the housing by means of a handle and to slide over the guide wall from the operating position into the folded position and vice versa. If the sliding element is released, the spring pushes it back into its starting position and blocks the holding element, so that the pawl is fixed in the respective engagement and the position of the steering axis is also securely fixed.
    Further advantages, features and possible uses of the present invention
    result from the following description in conjunction with the exemplary embodiments shown in the drawings.
    In the description, in the claims and in the drawing, the terms and assigned reference symbols used in the list of reference symbols given below are used. In the drawing means:
    [0023] FIG. 1 shows an illustration of a foldable scooter according to the invention;
    [0024] FIG. 2 is a side plan view of the joint of the scooter in the deployed operating position; and
    Fig. 3 is a side plan view of the joint of the scooter in the folded folded position.
    1 shows an embodiment of a scooter 10 according to the invention, comprising a footboard 12 and a steering axle 14 which has a steering axle holder 16. The steering axle 14 is connected to the footboard 12 via the steering axle holder 16. The steering axle holder 16 is formed at its upper end with a guide tube 18 in which the steering axle 14 is guided. The guide tube 18 is supported on the front fork 20. At its second end, the steering axle holder 16 is fastened in a lockable manner via a joint 22 on the footboard 12. The joint 22 has an axis of rotation R about which the steering axis holder 16 is rotatably mounted. The steering axle 14 can assume two positions: an unfolded, built-up operating position and a folded position. These two positions are secured in the joint 22 by a locking mechanism 24. The locking mechanism 24 of the joint 22 can only be actuated via a safety device 50, as is described below.
    In Fig. 2, the built-up operating position of the joint 22 of the scooter 10 is shown. The joint 22 has a housing 26 which is fastened to the front end of the footboard 12. The housing 26 is designed with a pair of tabs 28, consisting of two tabs 28 spaced apart from one another. In the present case, only one tab 28 of the pair of tabs 28 is shown for reasons of clarity. The pair of tabs 28 is fastened to the step 12 by means of a screw or rivet connection, for example. On the front wheel side, a front plate 32 connects the two tabs 28 and on the upper side they are connected to one another via a guide wall 34. The guide wall 34 has two spaced-apart engagements 36a, 36b, the first engagement 36a securing the unfolded, built-up position of the scooter 10 and the second engagement 36b securing the collapsed, folding position of the scooter 10, as shown in FIG. 3. The pair of tabs 28 defines a curved slot 38 below their upper edge and a bearing bore above the footboard 12.
    The steering axle holder 16 is formed at its end on the footboard side to form a fork which is connected via a guide pin 42. The fork-shaped end of the steering axle holder 16 engages around the housing 26, the guide pin 42 sliding through the curved slot 38 of the pair of tabs 28. A bearing pin 40 connected to the fork of the steering axle holder 16 engages in the bearing bore of the housing 26.
    The locking mechanism 24 has a rotary shaft 44 which penetrates a bore in the steering axle holder 16 above the pair of tabs 28. The rotary shaft 44 has a flange at one free end and a handle 54 at the other free end. A rocker element 46 is arranged on the rotary shaft 44, which is designed as a pawl 47 at one end and has a holding means 48 at the other end. The pawl 47 can engage in the engagements 36a, 36b of the housing 26, securing the operating position or the folding position of the scooter 10. In the present case, the scooter 10 is in the unfolded operating position, the pawl 47 engaging in the engagement 36a on the front wheel. A tensioned spring 52 is arranged on the pawl 47 and presses the pawl 47 into the engagement 36a in order to secure the upright position of the steering axle 14.
    The holding means 48 of the locking mechanism 24 cooperates with a securing device 50, which has a spring 56, the tensioning force of which acts on a displacement element 60,
    includes. In the present case, the displacement element 60 can be displaced against the spring force via a handle 62 attached to the steering axle holder 16. The holding means 48 of the locking mechanism 24 lies on the sliding element 60. This arrangement blocks the rotary movement of the handle 54 and locks the pawl 47 in engagement 36a. Moving the handle 62 and thus the sliding element 60 against the spring force creates a clearance between the steering axle holder 16 and the holding means 48. This makes it possible to rotate the handle 54 against the force of the spring 52 to disengage the pawl 47 36a to solve. A rotary movement of the handle 54 is only possible if the sliding element 60 of the securing device 50 is released beforehand. Lifting the pawl 47 out of the engagement 36a enables the steering axle holder 16 to rotate about the axis of rotation R of the joint 22, the pawl 47 sliding over the guide wall 34 until it engages in the other engagement 36b, around the folding position of the scooter 10, as shown in FIG. 3.
    3 shows the folded up position of the joint 22 of the scooter 10, which is achieved by means of a folding movement of the steering axle holder 16. The steering axle 14 can be folded from an upright operating position into a folded-up folding position and vice versa. By releasing the sliding element 60 of the securing device 50 against the force of the spring 56, there is clearance for the holding means 48 of the locking mechanism 24. This in turn enables the pawl 47 of the locking mechanism 24 to be released from the engagement 36a, 36b of the housing 26 by means of the handle 54 is solvable. Thus, the pawl 47 can slide back and forth over the guide wall 34 of the housing 26 between the recesses 36a, 36b in order to fold the scooter 10 in a folding movement from the operating position into the folding position and vice versa. If the handle 62 of the sliding element 60 is released, the spring pushes the sliding element 60 back into its starting position, the holding element 48 being blocked so that the pawl 47 is fixed in the respective engagement 36a, 36b and the respective position of the steering axis 14 is securely fixed .
