1. An oscillating-mount split-hinge device configured to be fitted on a door that includes at least one panel that is mounted to pivot on a frame, the split-hinge device comprising:

  • at least one lower split-hinge configured to support at least the bulk of the load of the panel of said door; and

    at least one upper split-hinge configured to form an anti-tilting holding point and axial guide of the panel,wherein each of the lower split-hinge and the upper split-hinge comprisesone or more of a stationary split-hinge part integrated with the frame and a movable split-hinge part attached to and integrated with the panel, anda pivoting shaft configured to be integrated with one of the frame and the panel, the pivoting shaft being configured to enable rotatably guiding the movable split-hinge part relative to the stationary split-hinge part around said pivoting shaft,wherein insertion of an axial superposition of at least one ball roller bearing and at least one ball stop about the upper pivoting shaft allows for guiding rotation of the movable split-hinge part relative to the stationary split-hinge part around the pivoting shaft of the lower split-hinge the at least one ball roller bearing of the lower-split hinge being configured to support primarily radial loads, the at least one ball stop being configured to support primarily axial loads, the at least one ball roller bearing and the at least one ball stop of the lower split-hinge being configured to permit an angular lack of coaxiality of the stationary split-hinge part relative to the movable split-hinge part of the lower split-hinge, an application point of resulting contact actions of roller bearing elements of said ball stop being eccentric relative to the median plane of the ball stop, the ball stop being mated with the ball roller bearing such that said application point substantially corresponds to the pivoting center of the ball roller bearing, an axial spacing between the ball roller bearing and the ball stop being adjustable by an adjustment brace through which the lower pivoting shaft passes axially and is inserted between the ball stop and the ball roller bearing,wherein insertion of a superposition of at least one ball roller bearing about the upper pivoting shaft allows for guiding rotation of the movable split-hinge part relative to the stationary split-hinge part around the pivoting shaft of each upper split-hinge the at least one ball roller bearing of the upper split-hinge being configured to support primarily the radial loads, the at least one ball roller bearing of the upper split-hinge being configured to permit an angular lack of coaxiality of the stationary split-hinge part relative to the movable split-hinge part of the upper split-hinge, andwherein each movable split-hinge part comprises a hub configured to accommodate the corresponding pivoting shaft, the stationary split-hinge part of each lower split-hinge and upper split-hinge having a hinge shape that carries the pivoting shaft,the pivoting shaft of the lower split-hinge being mounted to rotate freely in the corresponding lower hub by successively passing through, from a base of the lower hub, the ball roller bearing, the adjustment brace, the ball stop, and a plain bearing forming a pivot connection that preserves play between the corresponding pivoting shaft and an inside sliding surface of said plain bearing to facilitate an angular offset of the pivoting shaft within the angular limits imposed by the ball roller bearing and said ball stop associated with the ball roller bearing, andthe pivoting shaft of each upper split-hinge being mounted to rotate freely in the corresponding hub by successively passing from a base of the upper hub, through the ball roller bearing and a plain bearing forming a pivot connection that preserves play to offset the upper pivoting shaft within angular limits imposed by the ball roller bearing.
