Definitions
- the invention relates to a folding scooter and a handlebar.
- Folding scooters are known from the prior art.
- Corresponding scooters usually have two axes, each with a floor roller, between which a running board is arranged.
- One of the floor casters can be steered via a handlebar, the steering rod of which is guided by a steering column which projects upward substantially perpendicularly to the running board when the scooter is ready to drive.
- the handlebars usually extend to both sides of the handlebar with their grips and are often height-adjustable.
- Such scooters usually have one or more
- the steering column with the handlebar guided therein can be pivoted into a position in which the steering column lies essentially parallel to the footboard.
- the handlebar grips may be in a substantially parallel position to the handlebar so that the handles no longer protrude laterally over the footboard when the scooter is folded together.
- the handles are fastened to the handlebars via a snap-in connection and are secured against loss using a rope. To fold the scooter, who detached the locking connections and attached the handles to side brackets on and parallel to the handlebar. To make the scooter ready to drive, the handles must be inserted and locked into the corresponding receptacle on the handlebars.
- the object of the present invention is to provide a folding scooter and a handlebar which no longer has the disadvantages known from the prior art or only has them to a minor extent.
- the invention relates to a folding scooter comprising a running board arranged between two axles, each with at least one floor roller, and a steering column connected to the running board for a handlebar of one of the two axles, the handlebar being a steering rod guided in the steering column with at least one in the unfolded state to the side of which it comprises a stretching handle, the at least one handle being pivotable about a folding axis about a folding axis relative to the steering column between a folded-out and a folded-in state, and one perpendicular to the folding axis rotatable securing sleeve is provided, which extends over the folding axis of the folding joint and which has a lateral recess, so that the handle in a first position of the securing sleeve is pivoted from the unfolded to the folded state and the handle in at least a second position of the securing sleeve in the unfolded condition is secured.
- the invention relates to a handlebar with a handlebar with at least one handle extending laterally in the unfolded state, the at least one handle being pivotable about a folding axis about a folding axis relative to the handlebar between an unfolded and a folded-in state, one vertically to
- Folding axis rotatable securing sleeve which extends over the folding axis of the folding joint and which has a lateral recess, so that the handle in a first position of the securing sleeve can be pivoted from the unfolded to the folded state and the handle in at least a second position Is secured in the unfolded state.
- the inventive combination of folding joint and rotatable locking sleeve perpendicular to the folding axis makes it easy to fold and unfold the handle of a handlebar.
- the axis for pivoting the handle is defined by the respective folding joint, the hedging sleeve, which extends over the folding axis, secures the handle in the unfolded state by the wall of the securing sleeve in the pivoting plane perpendicular to the folding axis on both sides in a form-fitting manner the folding axis lies on the folding joint.
- the locking sleeve is rotated from a corresponding two-th position to a first position
- the recess provided according to the invention, through which the folding hinge can then "swivel" in order to achieve the folded-in state.
- the securing sleeve must move from the first position back into the second position be rotated to secure the handle in the unfolded position.
- the securing sleeve in the folded state of the handle has a third position arranged between the first and second position for securing the handle in a folded state, in which the sleeve engages with the edge limiting the cut-out on a stop of the handle.
- the securing sleeve can no longer be turned into the second position.
- the securing sleeve can be rotated from the first position in the direction of the second position until the edge delimiting the saving lies on the handle or the folding joint. If a stop - for example a step or a groove - is provided in this area, into which the edge of the recess engages or against which the edge lies, the handle can be secured in the folded state.
- a return spring is provided for resetting the fuse sleeve from the first to the second and / or third position.
- a corresponding return spring can ensure that the securing sleeve inadvertently remains in the first position or is inadvertently turned into the first position.
- the locking sleeve is rotated by the return spring from the first position to the full second position or, for example, also to the third position depends on the position of the handle, that is, whether it is folded in or out.
- the folding axis can be substantially perpendicular to the handlebar, so that the handles are preferably essentially parallel to the handlebar when folded. Alternatively, it is possible that the folding axis is essentially parallel to the handlebar.
- the lateral protrusion of the handlebar over the running board can at least be reduced.
- the folded handle then points towards the running board.
- the recess points towards the footboard in the second position of the securing sleeve.
- the recess of the securing sleeve points downward when the folding scooter is used in the second position, so that the risk of dirt penetrating into the folding joint and the securing sleeve is reduced.
- the securing sleeve is mounted between the handlebar and the folding axis. In this case, the position of the securing sleeve does not change with the pivoting of the handle, but rather remains constant with respect to the handlebar.
- the outer diameter of the securing sleeve is preferably substantially the same as the diameter of the handle of the handlebar.
- the securing sleeve can then be used as an additional handle element in continuation of the actual handle.
- FIG. 1 a first embodiment of a folding scooter according to the invention with handles that can be folded in and out;
- Figure 3a-e schematic representation of the unfolding and folding of the handle according to Figure 2a, b.
- FIG. 1 A folding scooter 1 according to the invention is shown in FIG. 1
- the folding roller 1 comprises two axes perpendicular to the sheet plane, each with a bottom roller 3.
- the bottom roller 3 is rotatably mounted on one end of a footboard 4, while the other bottom roller 3 on a handlebar 10 with two on both sides of the Height-adjustable steering rod 12 of the handlebar 10 extending handles 11 is mounted.
- the handlebar 12 is rotatable in a steering column 5 leads GE, whereby the bottom roller 3 mounted thereon is steerable.
- the steering column 5 is connected to the footboard 4 via a folding joint 6. With the aid of the folding joint 6, the folding scooter 1 shown in the ready-to-drive state in FIG. 1 can be folded together such that the steering column 5 is oriented parallel to the running board 3.
- FIG. 2a one of the two handles 11 attached to the handlebar 12 of the handlebar 10 is shown in the extended state in greater detail.
- Figure 2b shows a sectional view through this handle 11. The other handle 11 is accordingly provided on the other side of the handlebar 10.
- the handle 11 is connected to the handlebar 12 via a folding joint 13.
- the folding axis 14 of the folding joint 13 runs parallel to the axis 12 'of the handlebar 12.
- One part 13' of the folding joint 13 is integrally formed on the handlebar 10, while the other part 13 '' is connected to the handle 11.
- the folding joint 13 comprises a securing sleeve 15 which is rotatably mounted about an axis 16 perpendicular to the folding axis 14 between the steering rod 12 and the folding axis 14.
- the securing sleeve 15 has an outer diameter that is essentially identical to the handle 11 and has a recess 17 which, in FIG. 2a, b, shows the second position of the securing sleeve 15 in the direction of the footboard 4 of the folding scooter 1 (see FIG. 1), this second position being defined by a limiting screw 18 cooperating with a stop.
- the securing sleeve 15 can basically be rotated in the direction indicated by the arrow 90, whereby a return spring 19 pushes back the securing sleeve 15 in the direction of the second position shown in FIGS. 2a, b. In this second position, any pivoting of the folding joint 13 is prevented by the securing sleeve 15.
- the handle 11 can be moved around pivot axis 14 in the direction of arrow 91 from the unfolded state shown in FIGS. 2a, b to a folded-in state.
- the securing sleeve 15 is pivoted about the axis 16 in the direction of the arrow 90 and against the remindstellfe of 19 in a first position, in which the recess 17 extends substantially parallel to the folding axis 14. This position is shown in Figure 3b.
- the securing sleeve 15 must be held in the first position shown festge, so that it does not snap back due to the return spring 19 in the second position (see FIG. 3a), in which the handle is fixed in the extended position.
- the handle 11 can be pivoted about the folding axis 14 into a folded-in state, specifically in the direction of the recess 17. The same is shown in FIG. 3c.
- the securing sleeve 15 is released so that it basically pushes back to the second position due to the return spring 19 (cf. FIG. 3a). Because the handle 11 is now pivoted into the folded state, the securing sleeve 15 does not reach the second position, however, part 13 ′′ of the folding joint 13 assigned to the handle 11 or the handle 11 in the third shown in FIG. 3d
- an edge 17 ′ delimiting the recess 17 of the securing sleeve 15 engages in a stop 20 of the part 13 ′′ of the folding joint 13 assigned to the handle 11.
- the stop 20 is formed by a step 21, one side of which extends parallel to the folding axis 14 and the axis 16 when the handle is folded.
- the securing sleeve 15 In order to be able to convert the handle 11 from the folded state shown in FIG. 3d, e back to the folded state shown in FIG. 3a, the securing sleeve 15 must first be brought back into its first position (see FIG. 3c) , before the handle 11 can then be pivoted into the desired unfolded position (cf. FIG. 3b). If the securing sleeve 15 is then released, it moves due to the return spring 19 into the second position according to FIG. 3a, whereby the handle 1 is secured in the then unfolded position.
