Abstract

Battery unit for an electronic price label and an electronic price label, which includes a separate, external, replaceable battery unit having a battery, and a fastening means, which may be detachably fasten the battery unit to the frame part of the electronic price label.

Claims

1. An electronic price label, comprising:

a frame part of the electronic price label;

a separate, external, replaceable battery unit, which comprises a battery; and

a first fastener, which is adapted to detachably fasten the battery unit to the frame part of the electronic price label or into connection with said frame part,

wherein the first fastener comprises a stud or spike for fastening the electronic price label to a product, and

wherein the first fastener, the frame part of the electronic price label and/or the battery unit are arranged so that the first fastener can be turned into a first position in a direction of the frame part and into a second position at a right angle to the frame part.

2. The electronic price label according to claim 1, further comprising a first electrical connector part and a second electrical connector part fitted into connection with the frame part, and

wherein the first fastener detachably fastens the battery unit to the frame part of the electronic price label in such a way that connection poles of the battery of the battery unit are in electrical contact with the first electrical connector part and the second electrical connector part.

3. The electronic price label according to claim 2, wherein the connection poles of the battery are in continuous electrical contact with the first electrical connector part and the second electrical connector part.

4. The electronic price label according to claim 2, further comprising conductors for conducting current from the connection poles of the battery to the first electrical connector part and to the second electrical connector part of the electronic price label, and the connection poles of the battery are in continuous electrical contact with the first electrical connector part and/or the second electrical connector part via means for conducting current.

5. The electronic price label according to claim 1, further comprising conductors arranged in the battery or in connection with the battery.

6. The electronic price label according to claim 1, wherein at least one connection pole of the battery is in wireless electrical contact with the electronic price label.

7. The electronic price label according to claim 6, further comprising a primary loop or primary winding in connection with the battery and a secondary loop or secondary winding in connection with the frame part.

8. The electronic price label according to claim 1, wherein a surface of the frame part is essentially planar and the battery unit is adapted to be fastened onto the essentially planar surface of the frame part.

9. The electronic price label according to claim 1, wherein the first fastener further includes a magnetic lock.

10. The electronic price label according to claim 1, wherein a second end of the stud or spike is arranged to be of essentially semicircular shape.

11. The electronic price label according to claim 1, wherein the stud or spike and a magnetic lock fasten the battery to the frame part.

12. The electronic price label according to claim 1, wherein the battery unit comprises a protective casing of the battery, which protective casing forms a recess for the battery.

13. The electronic price label according to claim 1, wherein the battery unit further comprises an intermediate part, which is adapted to be fastened between the battery and the frame part of the electronic price label.

14. The electronic price label according to claim 13, wherein the intermediate part, the battery and a protective casing of the battery are fixed to each other.

15. The electronic price label according to claim 13, further comprising a second fastener for fastening the intermediate part to the protective casing.

16. The electronic price label according to claim 15, further comprising a third fastener for fastening the frame part to the intermediate part.

17. The electronic price label according to claim 13, further comprising a second fastener for fastening the intermediate part to the protective casing and a third fastener for fastening the intermediate part to the frame part.

18. The electronic price label according to claim 13, wherein the price label further comprises fastening means for fastening the intermediate part to a protective casing and a fastening means for fastening the intermediate part to the protective casing is arranged in the structure of the protective casing or in connection with the protective casing and/or in the structure of the intermediate part or in connection with the intermediate part.

19. The electronic price label according to claim 5, wherein at least one of the conductors is a spring.

20. The electronic price label according to claim 1, wherein the electronic price label further comprises a remotely readable identifier.

21. The electronic price label according to claim 20, wherein the remotely readable identifier is arranged in connection with the battery unit.

22. The electronic price label according to claim 1, further comprising a memory, which is adapted to retain information when the current is disconnected.

23. The electronic price label according to claim 2, wherein the first electrical connector part and the second electrical connector part are adapted to conduct current from the connection poles of the battery to a circuit board or a display of the electronic price label.
