The present invention refers to a supporting device for facilitate a working activity in a knelt down position.
Presently in the mechanic field exist beds provided with wheels which permit to work under a car.
Besides there are little working chairs provided with wheels which permit to seat and make some operations in particular on the cars.
Both do not permit to make a working activity on a knelt down position.
Today there are much working activity, in particular in the mechanic field, in which it is frequently necessary to operate in a knelt down position for a long time, and work in this position often cause fatigue and pain.
Purpose of the present invention it is to realize a supporting device for facilitate a working activity in particular in a knelt down position which permit to an user to pass easily and quickly from a stand up position to said knelt down position and vice versa, and that at the same time permit to avoid instability and rotations of the same supporting device during the passage from a position to the other.
Another purpose is to realize a supporting device for facilitate a working activity in particular in a knelt down position which should be stable and that permit to an user to maintain the same position and the same freedom of movement as if the supporting device were not present.
Still another purpose is to have a supporting device for facilitate a working activity in particular in a knelt down position that permit to an user to easily get down on his knees and to agilely move himself maintaining said knelt down position.
Still another purpose is that to have a supporting device for facilitate a working activity in particular in a knelt down position that should be not cumbersome and that should be easy to transport.
Further purpose is that to have a supporting device for facilitate a working activity in particular in a knelt down position that can be easy to realize and easy to assemble.
These purposes according to the present invention are reached realizing a supporting device for facilitate a working activity in particular in a knelt down position according to claim 1.
Further features of the invention are pointed out in the following claims.
The features and the advantages of a supporting device for facilitate a working activity in particular in a knelt down position according to the present invention will appear more evident from the following illustrative and not limitative description, referred to the attached schematic drawings in which:
