Abstract
An electronic shelf label system includes a powered rail for holding electronic shelf labels. The front side of the rail includes a recess that is physically configured to receive a protrusion at the upper rear side of the shelf label. The shelf label further comprises a lower hook member for engaging with a lower edge of the rail. The rail may comprise two conductors for providing the labels with power and data for display on the label. Data and power may be provided via a controller and power module connected to the back of the rail.
Claims17
A rail for holding a shelf label, the rail having a front side and a rear side, the rail comprising:
- an elongated body having a substantially flat front surface;
- an elongated top member having a lower surface, the top member being connected to the body such that the top member protrudes horizontally from the front surface away from the rear side and the lower surface is provided substantially perpendicularly to the front surface, and the top member further having a top protrusion protruding downwardly and substantially perpendicularly from the lower surface, the top protrusion for receipt by a recess at the top of the label;
- and
- a first conductor and a second conductor provided substantially parallel to one another along the length of the rail and being embedded in the elongated body such that they do not extend beyond the front surface,
- wherein the elongated body comprises a front recess in the front surface, the front recess being at an upper side delimited by the top member.
The rail according to 6, further comprising a rear surface opposite to the front surface, wherein a wall of the first conductor cavity and a wall of the second conductor cavity protrude from the rear surface;
- the body further comprising a rear connector arranged to engage with an accessory connector comprised by an auxiliary device, the rear connector being provided at the rear surface and comprising a connector cavity having an opening at the rear side, wherein and the connector cavity is provided between the first conductor cavity and the second conductor cavity.
An electronic shelf label for displaying information, the shelf label comprising:
- a label body having a front side for displaying information, a rear side opposite to the front side and a top side at the top of the label body;
- a lower hook member protruding from a lower portion of the rear side having an upwardly facing opening configured to receive a lower edge of a rail for holding the electronic shelf label, the rail for fixation to a shelf;
- and
- a rear protrusion protruding from the top of the rear side having a closed upper side substantially flush with an upper side of the label body.
A rail for holding at least one shelf label, and a controller module for controlling the at least one shelf label, the rail, the rail having a front side and a rear side, the rail comprising:
- an elongated body having a substantially flat front surface;
- an elongated top member having a lower surface, the top member being connected to the body such that the top member protrudes horizontally from the front surface away from the rear side and the lower surface is provided substantially perpendicularly to the front surface, and the top member further having a top protrusion protruding downwardly and substantially perpendicularly from the lower surface, the top protrusion for receipt by a recess at the top of the label;
- the controller module for controlling at least one electronic shelf label provided on the rail for holding the at least one_electronic shelf label, the controller comprising:
- a housing for housing control electronics configured to control the electronic shelf label;
- and
- a controller connector comprising a protrusion protruding from the controller module and being wider at a distance from the controller module, the protrusion comprising at least a first controller electrode and a second controller electrode, the controller connector arranged to engage with a rear connector cavity of the rail.
An electronic shelf label system comprising:
- (a) a rail having a front side and a rear side, the rail comprising:
- an elongated body having a substantially flat front surface;
- an elongated top member having a lower surface, the top member being connected to the body such that the top member protrudes horizontally from the front surface away from the rear side and the lower surface is provided substantially perpendicularly to the front surface;
- and the top member further having a top protrusion protruding downwardly and substantially perpendicularly from the lower surface, the top protrusion for receipt by a recess at the top of the label;
- and
- a first conductor and a second conductor provided substantially parallel to one another along the length of the rail and being embedded in the elongated body such that they do not extend beyond the front surface,
- wherein the elongated body comprises a front recess in the front surface, the front recess being at an upper side delimited by the top member;
- (b) an electronic shelf label comprising:
- a label body having a front side for displaying information, a rear side opposite to the front side and a top side at the top of the label body;
- a lower hook member protruding from a lower portion of the rear side having an upwardly facing opening configured to receive a lower edge of a rail for holding the electronic shelf label;
- and
- a rear protrusion protruding from the top of the rear side having a closed upper side substantially flush with an upper side of the label body;
- and
- (c) a controller module including a housing for housing control electronics configured to control the electronic shelf label;
- and
- (d) a controller connector comprising a protrusion protruding from the controller module and being wider at a distance from the controller module, the protrusion comprising at least a first controller electrode and a second controller electrode, the controller connector arranged to engage with a rear connector cavity of the rail.
