Abstract

A chairless chair exoskeleton in order to provide seating support to the user while the user is standing particularly in industrial field includes at least one foot connection element for being connected to the foot of the user and at least one calf support element connected to said foot connection element, and at least one thigh support element connected to said calf support element by means of at least one joint and at least one energy storage element associated to the thigh support element from one side and associated to the calf support element from the other side.

First claim

What is claimed is:

1. A chairless chair exoskeleton in order to provide a seating support to a user while the user is standing particularly in an industrial field, comprising
at least one foot connection element for being connected to a foot of the user, and at least one calf support element connected to the at least one foot connection element, and
at least one thigh support element connected to the at least one calf support element by means of at least one joint and at least one energy storage element, wherein the at least one energy storage element is associated to the at least one thigh support element from a first side and associated to the at least one calf support element from a second side,
wherein the subject matter chairless chair exoskeleton comprises
at least one movement groove provided on the at least one calf support element;
an activation arm, wherein the activation arm is associated to the at least one energy storage element from one side and positioned in a manner at least partially displacing in the at least one movement groove from another side;
a locking arm, wherein the locking arm is connected from one side in a manner linearly displacing in the at least one movement groove, and the locking arm extends in a manner making a downward protrusion from the at least one foot connection element in a direction of the at least one calf support element; and
the locking arm is configured that when a first end of the locking arm presses to the ground, a second end of the locking arm fixes one end of the activation arm in the at least one movement groove.

2. The chairless chair exoskeleton according to claim 1 , wherein the activation arm is configured to provide the at least one energy storage element to be in at least one free position by means of releasing from a resting of the locking arm as the user lifts his/her heel from the ground.

3. The chairless chair exoskeleton according to claim 1 , wherein the at least one energy storage element is connected to the locking arm in a movable manner by means of at least one activation arm.

4. The chairless chair exoskeleton according to claim 1 , wherein the activation arm is configured to rotate in an axis of the activation arm at least partially at two end parts.

5. The chairless chair exoskeleton according to claim 1 , wherein a foot embodiment of the locking arm is configured to contact the ground by means of at least one housing provided at a rear part at least partially.

6. The chairless chair exoskeleton according to claim 1 , wherein at least one spring is provided, and the at least one spring is configured to drive a downward and upward directional movement of the locking arm.
