the user can then let go of the board which remains perfectly balanced in a horizontal position resting on his shoulder through the intermediary of the device so that only very low forces need to be exerted on the crossmembers 4 and 5 and the muscles of the head are not fatigued the head incidently not having to support any vertical load the user can then walk to his destination and proceed to off load the board by carrying out the loading maneuvers in reverse noting that the shoulders of a normal person are slightly arcuate towards the front the comfort and the distribution of the load may be improved by placing the two shoulder members 1 not in parallel planes but in planes slightly convergent in the forward direction by way of further improvements each shoulder member 1 may be provided with a vertical tubular part disposed to rotate freely inside the corresponding upright 3 also formed by a tubular part which enables the two members 1 to assume automatically the best possible orientation this arrangement also enables the members 1 to be turned to lie flat in the plane of the uprights 3 the portage frame 2 may also be pivoted to the upper ends of the uprights 3 by means of two pivots 8 with horizontal axes aligned with one another and offset below the frame to permit it to be folded into a plane parallel to and contiguous with the plane of the uprights 3 in order facilitate storage and.
