Abstract: The invention relates to an electronic labelling device formed by a label holder and at least one electronic label. The electronic label is formed by a display screen (8), an electronic unit (9) and a connecting plate (10). The back of the screen (8) comprises a rib (12) for hooking to a groove in the label holder such that only the screen (8) is visible.

Abstract: The invention relates to an electronic labelling device formed by a label holder and an electronic label. The front portion (4) of the label holder includes a substantially flat front face (6) comprising an elastically deformable omega-shaped groove (7) intended to receive an omega-shaped rib belonging to the label.

Abstract: Electronic labelling system with rail 1 supporting labels fixed onto the edge face of a shelf, the rail and the shelf having the same height, the rail 1 having a free edge 8 and a top groove 9. The electronic label 2 bears a ridge 15 that can be inserted into the groove 9 of the rail 1, and a member 16 for fixing to the free edge 8 of the rail 1.

Abstract: A sign support comprises a rear portion (1) and a front portion (2) interconnected by a flexible hinge (3), and means for adjusting the inclination of the front portion (2) relative to the rear portion (1). An abutment element (12) is connected by a breakable connection (13) to one of said rear and front portions (1 and 2) and defines with the latter a trough (12) of which one free edge constitutes an abutment to define a first position, substantially vertical, of the front portion (2), said abutment element (12) being adapted to be removed by rupture of the breakable connection (13) to define a second position of the front portion (2) of downward inclination.

Abstract: A labeling system includes an open housing (3) having a bottom (37), an upper wing (31) and a lower wing (32), an electronic label (2) adapted to be positioned in the open housing (3) and having a hook (23, 24) coacting with the wings (31, 32) of the housing (3), a suspension element (4) with two walls (41, 42) disposed parallel to each other and connected by a cylindrical portion (43) adapted to be disposed astride the crosspiece (12) of a display unit with a peg (1), and a positioning device (35, 25, 45) which ensures the relative positioning and retention of the housing, of the label and of the suspension element, and which are inaccessible when the electronic label is positioned in the housing.

Abstract: This labeling system comprises an open housing (3) having a bottom (37), an upper wing (31) and a lower wing (32), an electronic label (2) adapted to be positioned in the open housing (3), in the form of a flat rectangular parallelepipedal body with a display screen (27) on its front surface (26), and comprising hooking means (23, 24) coacting with corresponding means (33, 34) of the wings (31, 32) of the housing (3), a suspension element (4) comprising two walls (41, 42) disposed parallel to each other and connected by a cylindrical portion (43) adapted to be disposed astride the crosspiece (12) of a display unit with a peg (1), and positioning means (35, 25, 45) which ensure with the hooking means of the label and the corresponding means of the wings on the housing, the relative positioning and retention of the housing, of the label and of the suspension element, and which are inaccessible when the electronic label is positioned in the housing.

Abstract: Electronic labeling system includes a rail for supporting labels and at least one electronic display label, the rail having two facing wings with each of the wings having in its medial region a longitudinal groove, the electronic label having on one of its two opposite edges a longitudinal rib adapted to be inserted in the groove of one of the rail wings and on the other of the opposite edges at least one retractable pin adapted to snap into the groove of the other rail wing, and at least one recess in which is disposed a ferromagnetic core carrying the pin which is urged to project from the corresponding edge of the label, the core being adapted to be displaced in the recess by magnetic attraction to retract the pin and free the label.

Abstract: The primary interface (2) is connected to all secondary interfaces (3) by a single two-wire line (2) carrying an alternating supply current under low voltage, and control and test data in the form of pulses; each secondary interface (3) is connected to all its labels (4) by a single two-wire line (34) carrying an alternating supply current under very low voltage, and control and test data in the form of pulses; all data are transmitted using the carrier current principle.
