## Abstract

A therapeutic walking trainer with a foot receiving portion for receiving at least a sub-region the forefoot of a user or for forming a connection with a toe of a shoe, having at least one main carrier which can be displaced in and/or counter to an adjustment direction, and with an actively and/or passively operable adjustment unit for the relative adjustment, oriented essentially perpendicular to the adjustment direction, of the foot receiving portion relative to the at least one main carrier.

## Claims

### Claim 1

A therapeutic walking trainer comprising:
a foot receiving portion for receiving at least a sub-region of a of a user or for forming a connection with a toe of a shoe;
at least one main carrier that is adapted to be displaced in and/or counter to an adjustment direction; and
an actively and/or passively operable adjustment unit for the adjustment of the foot receiving portion between a raised position and a lowered position relative to the at least one main carrier,
wherein a top surface of the at least one main carrier, that faces the foot receiving portion, is a tread surface, and
wherein, when the foot receiving portion is in the lowered position, a portion of the foot or the shoe of the user directly contacts and treads on the tread surface, and wherein, when the foot receiving portion is in the raised position, the portion of the foot or the shoe of the user is lifted off the tread surface, so as to be spaced apart from the tread surface; wherein the portion of the foot or the shoe of the user, that either directly contacts and treads on the tread surface or is spaced apart from the tread surface, is the forefoot of the user or the toe of the shoe.

### Claim 2 (depends on 1)

The therapeutic walking trainer according to claim 1, further comprising a traction element or a pressure element.

### Claim 3 (depends on 2)

The therapeutic walking trainer according to claim 2, wherein the foot receiving portion and/or a supporting carrier is associated with an actuator, via which the foot receiving portion and/or the supporting carrier are adjustable relative to the at least one main carrier between a raised position and a lowered position.

### Claim 4 (depends on 3)

The therapeutic walking trainer according to claim 3, wherein the actuator is associated with an actuator drive for motorized adjustment of the foot receiving portion and/or the supporting carrier.

### Claim 5 (depends on 3)

The therapeutic walking trainer according to claim 3, wherein the traction element or the pressure element is coupled to the actuator, wherein the foot receiving portion and/or the supporting carrier are adjustable by an actuation of the actuator via the traction element or via the pressure element, and wherein the at least one main carrier is adapted to be pushed, pulled or pressed in and/or counter to the adjustment direction by actuating the actuator via the traction element or via the pressure element.

### Claim 6 (depends on 3)

The therapeutic walking trainer according to claim 3, wherein the actuator is pivotally connected to the at least one main carrier, wherein the actuator is associated with a control element which interacts with a control cam provided on a foot receiving portion and/or on the supporting carrier, and wherein the foot receiving portion and/or the supporting carrier are adjustable by adjusting the control element relative to the control cam.

### Claim 7 (depends on 2)

The therapeutic walking trainer according to claim 2, wherein the adjustment unit comprises a supporting carrier which is pivotally connected at one end to the at least one main carrier, and at the other end non-rotatably or pivotally connected to the foot receiving portion, wherein the traction element or the pressure element is coupled with the supporting carrier such that the at least one main carrier is adapted to be pushed, pulled or pressed in and/or counter to the adjustment direction by actuating the supporting carrier via the traction element or via the pressure element.

### Claim 8 (depends on 2)

The therapeutic walking trainer according to claim 2, wherein the traction element or the pressure element is coupled to the at least one main carrier such that the main carrier is adapted to be pushed, pulled or pressed in and/or counter to the adjustment direction.

### Claim 9 (depends on 1)

The therapeutic walking trainer according to claim 1, wherein a holder is provided which comprises a harness system.

### Claim 10 (depends on 9)

The therapeutic walking trainer according to claim 9, wherein the holder is formed of a vertical part, a horizontal part, and a bent section connecting the vertical part with the horizontal part.

### Claim 11 (depends on 1)

The therapeutic walking trainer according to claim 1, wherein the at least one main carrier is associated with a drive that provides a motor-driven adjustment or displacement of the at least one main carrier in and/or counter to the adjustment direction.

### Claim 12 (depends on 1)

The therapeutic walking trainer according to claim 1, wherein the adjustment unit comprises a supporting carrier, wherein a first end of the supporting carrier is pivotally connected to the at least one main carrier, and a second end of the supporting carrier is non-rotatably or pivotally connected to the foot receiving portion.
