- the shape of the sole is also designed so that the other components of the climbing aid do not touch the ground even during normal walking, which includes, for example, rolling the user's foot and thus do not represent an obstacle while walking.
- the sole is adapted to the basic shape of the shoe support so that it does not have any when using the climbing aid to climb the step axes Is an obstacle, in particular such that it does not hinder the simple hooking of the hooking devices.
- the basic shape of the sole can predominantly correspond to the shape of the base plates, or it can also cover only a section or partial area of the base plates.
- the climbing aid comprises at least one folding mechanism for the first hooking device and / or a folding mechanism for the second hooking device.
- the at least one folding mechanism is suitable for folding up the first hooking device and / or the second hooking device in relation to the shoe support.

The user now preferably checks the safe stance and the correct setting of the climbing aid.
- the method can also be used for going down, whereby it should be noted that the stance direction must always be selected so that the toe end of the shoe support, which corresponds to the toe end of the climbing aid, must point to a higher step axis.
- the climbing aid must therefore be used in reverse when going down.
- the climbing aids in such a way that it is also possible to run down in forward gear.
- Such an addition can be a rotating mechanism with a snap-in option.

- the climbing aids include one or more folding mechanisms for folding up one or more hooking devices, it may be necessary to fold down the hooking devices again before climbing the step axes, provided that the folding mechanisms were previously used to fold up one or more hooking devices.
- the fastening of the first and second climbing aids can be preceded by an adjustment of the climbing aids to the respective escalator or the distances between the exposed step axes of the escalator, provided that the climbing aid includes the adjustment option described above.
- the setting can also be made during or after climbing the step axes, but care must be taken to ensure that the user is standing and / or held securely while the setting options, for example the connecting link of the second hooking device, are loosened.
- the aim of setting the climbing aids can be that the shoe support of each climbing aid is as horizontal as possible when climbing the step axes, so that the user has the impression that he is standing on a predominantly horizontal surface, for example a step on a staircase or escalator. Correct setting ensures a safe and comfortable stance for the user and fatigue-free work.
- favorable embodiments of the invention can enable quick and uncomplicated access to escalators in which the steps have also been removed in large sections. This can make work on escalators easier, for example if only one or two steps have to be removed and then reinstalled to replace the stepped set. Troubleshooting, repairs, or routine maintenance can also change make it easier, as the relevant areas can be quickly reached, checked and processed.

- FIGS. 4a and 4b show a climbing aid with an angle actuator and a sole.
- FIG. 1 An embodiment of a climbing aid 100 is shown in FIG.
- the climbing aid is designed so that it is suitable for climbing step axles 110, 112.
- the step axis 110 is a first step axis and the step axis 112 is a second step axis.
- the climbing aid 100 comprises a shoe support 120 which includes a heel-side base plate 124 and a toe-side base plate 126.
- the base plates 124 and 126 are connected to one another via a connecting member 122.
- the connecting member 126 offers the possibility of adjusting the distance between the base plates 124, 126 so that the climbing aid 100 can be adapted to different shoe sizes.
- a bracket 128 is attached to the toe end of the shoe support 120, into which a shoe (not shown) can be pushed so that it is fixed there.
- a bracket 129 which fixes the shoe at the heel end.
- further straps can be provided for fastening the shoe (not shown).
- the climbing aid 100 comprises a first hooking device 130 at the heel end of the climbing aid, as well as a second hooking device 140 at the toe end of the climbing aid 100 Use rests on the step axis 110 along a length that is approximately the Width of the climbing aid 100 corresponds. This creates a form fit to the first step axis 110, which prevents any movement in a non-axial direction.
- the second hooking device 140 comprises two partial hooks spaced apart in the axial direction, both of which are open at the bottom in the same way as the hook of the first hooking device 130 and are designed to form a form fit to the second step axis 112, the width of the second hooking device being approximately the width of the first hooking device is equivalent to.
- the embodiment shown with two partial hooks offers an advantageous weight saving, which is particularly effective in this area due to the spacing of the partial hooks from the shoe support 120.
- a hooking device 140 with a continuous hook comparable to the hooking device 130 can also be used, for example to increase the stability of the component.
- the second hooking device 140 includes a connecting member 142 which, in the form of the angle actuator 150, includes an adjustment option for setting the angle of the second hooking device 140 in relation to the shoe support 120.
- the angle actuator 150 is shown enlarged in Figure lb.
- the locking screw 154 is provided with a knurled head so that it can be opened or closed by hand without a tool.
- a climbing aid 200 is shown in side view as it is present after it has been attached to the shoe 210 of a user.
- the climbing aid 200 largely comprises the components of the embodiment from FIGS. 1 a, b, so that the same reference symbols are used for the same features.
- the shoe 210 is first inserted into the bracket 128 for attachment, and then the heel is inserted into the bracket 129.
- the climbing aid is then fixed to the shoe 210 by means of tape 220.
- further straps can be provided for fastening the shoe (not shown).
- the opening on the bottom of the hooks of the hooking devices 130, 140 described in connection with FIG. 1 a can be seen particularly clearly.
- the openings have a cross section which corresponds to a section of a circle, the diameter of which is slightly larger than the diameter of the step axes 110, 112, which are to be climbed with the climbing aid. This ensures that tolerances or inaccuracies to be expected are compensated for during use and that the climbing aid locks itself to a small extent in accordance with the position of the step axes.
- the change in the angle is particularly noticeable as a change in the position of the hook of the second hooking device 140.
- the change in the angle means a rotation of the hook of the second hooking device 140 along a circular path 250, whereby it can also be seen that the axis of the angle actuator 150 lies parallel to the axis of the hook cross section of the hooking device 140 and the step axis 112.
- a change in the angle of the hooking device 140 and the change in the position of the hook of the hooking device 140 along the direction 250 thus does not change the axis of the hook cross section in relation to the step axis 112.
- a climbing aid 300 is shown, which represents an extension of the climbing aid 200, so that only the decisive differences will be discussed.
- the climbing aid 300 in the area of the connecting member 142 of the second hooking device 140 includes an adjustment option for adjusting the length of the connecting member 142 in the form of the length adjusting member 310. Adjusting the length of the connecting member 142 thus enables the position of the hook of the second hooking device to be changed 140 also in direction 350.
- a largely arbitrary positioning of the hook of the hooking device 140 along the directions 250, 350 is possible.
- This has the advantage that the climbing aid 300 shown can be used for the differently arranged step axes of escalators from different manufacturers, as well as for different escalator inclinations from the same manufacturer.
- FIG. 3b a possible embodiment of a connecting member 142 is shown, which comprises both an angle control element 150 and a catch control element 310.
- the angle actuator 150 corresponds to the design as it has already been explained in connection with FIG. 1b and is not described again here.
- the catch actuator 310 of the example shown includes a scaling 360 which enables the user to carry out a rough adjustment of the climbing aid far away from the escalator.
- the angles shown here are common inclinations of the middle section of escalators.
- the catch actuator 310 is designed as a telescopic linkage, in which a first part of the connecting member 320 can be retracted into a rail 322.
- the rail has a catch hole 324 along the catching direction, through which a locking screw 354 fastened to the first part of the connecting member 320 is guided.
- the locking screw 354 when open, allows the first part of the connecting link 320 to move in the rail 322 such that the overall length of the connecting link 142 changes, but not the angle of the first part of the connecting link 320 in relation to the rail 322
- the locking screw 324 is closed, a contact pressure arises between the rail 322 and the first part of the connecting member 320 guided therein, so that these components are fixed with respect to one another.
- the screw 324 is designed as a knurled screw so that it can also be opened or closed without a tool.
- a climbing aid 400 is shown in FIG. 4a, which represents a further embodiment of the climbing aid 100, so that only the decisive differences will be discussed.
- the climbing aid 400 comprises a sole attached to the ground, which comprises a sole of the first base plate 410 and a sole of the second base plate 412.
- the sole makes it easier for the user to walk on normal ground, so that the climbing aid can also be used on the shoe during other activities can be left without disturbing.
- the sole prevents components of the hooking devices 130, 140 and the shoe support 120 from resting and subsequently from being worn away Protection against slipping.
- FIG. 4b shows a front view of the climbing aid 400, from which it becomes clear that the sole of the first base plate 410 and the sole of the second base plate 412 behind it represent the only contact surface between the ground and the climbing aid when walking normally on flat ground. It can also be seen that a lateral protrusion of the soles has been avoided, so that the risk is reduced that the sole interferes with the hooking of the hooking devices 130, 140 into the step axles 110, 112.
- the illustrated embodiments of the climbing aid according to the invention include several optional features. Some of these features have been shown in combination with other features. However, it is clearly evident to the person skilled in the art that any combination of these features is possible in order to obtain favorable embodiments.
- a climbing aid according to the invention can comprise a connecting element without actuators, with an angled actuator 150, a length actuator 310, or a combination of angled actuator 150 and length actuator 310.
- the climbing aid according to the invention can, as shown in all examples, comprise a shoe support 120 which offers an adjustment option for adapting to the size of the user's shoe 210, but this feature is not absolutely necessary to achieve the desired effect; other shoe supports known from the prior art can be used.
- each of the climbing aids that are conceivable in this way can be designed with a sole, wherein the sole, as described in FIGS. 4a and 4b, can comprise several parts.
