Two-position tab

1. A tabbing apparatus, comprising:

a pocket; and

a tab element disposed within the pocket in a retracted position and including:

an indexing segment protruding from the pocket in an extended position as a tab and being received within the pocket in the retracted position, the indexing segment configured for displaying writing thereon for indexing a file,

an anchor portion, and

an intermediate portion pivotably connecting the anchor portion and indexing segment;

wherein the anchor portion is anchored to pocket so that, the intermediate portion pivots during the movement of the index segment between the retracted and extended positions.

2. The tabbing apparatus of claim 1 , wherein the indexing segment, intermediate portion and anchor portion are hingedly connected to each other for allowing the indexing segment to slide between the retracted position and the extended position.

3. The tabbing apparatus of claim 2 , wherein the indexing segment, intermediate portion and anchor portion are hingedly connected to each other for allowing the indexing segment to slide substantially linearly between the retracted position and the extended position.

4. The tabbing apparatus of claim 1 , wherein the indexing segment, intermediate portion and anchor portion are hingedly connected to each other for allowing the indexing segment to move between the retracted position and the extended position while substantially retaining an orientation.

5. The tabbing apparatus of claim 1 , wherein the tab element has a mid position in which the indexing segment is disposed between the extended and retracted positions, the pocket comprising a resilient member associated with the tab element the biasing the indexing segment away from the mid position toward the extended or retracted position depending on which side of the mid position the indexing segment is positioned.

6. The tabbing apparatus of claim 5 , wherein the resilient member is associated with the tab element such that the indexing segment in the retracted and extended positions is stably at rest.

7. The tabbing apparatus of claim 1 , wherein the intermediate portion comprises a plurality of intermediate segments connected by hinges between the anchor portion and the indexing segment so that the hinges are pivoted progressively along the intermediate portion during the movement between the retracted and extracted positions.

8. The tabbing apparatus of claim 5 , wherein the resilient member comprises a resilient wall of the pocket that is flexed by the intermediate portion in the mid position.

9. The tabbing apparatus of claim 8 , wherein the intermediate portion is hingedly connected to the anchor portion and indexing segment for pivoting during movement of the indexing segment between the retracted, mid, and extended positions, wherein the pocket has a cross-section that is elongated in depth and has a width, and the intermediate portion biases the resilient wall to increase the width of the pocket in the mid position compared to in the retracted and extended positions of the indexing segment.

10. The tabbing apparatus of claim 9 , wherein the intermediate portion extends at least partially widthwise with respect to the pocket in the mid position for biasing the resilient wall to increase the pocket width.

11. The tabbing apparatus of claim 1 , wherein the pocket is disposed at an edge of a file for indexing the file.

12. A file, comprising:

a first panel having an edge and being configured and dimensioned for holding papers; and

the tabbing apparatus of claim 1 , wherein the pocket is provided on the first panel near the edge such that the indexing segment protrudes beyond the edge in the extended position.

13. The file of claim 12 , wherein the file comprises a second panel having an edge and being hinged with respect to the first panel for holding papers therebetween, wherein the indexing segment extends beyond the edge of the second panel in the extended position.

14. The file of claim 12 , wherein the file is folded to provide the first and second panels.

15. The tabbing apparatus of claim 1 , further comprising an adhesive on the pocket configured and disposed for attachment to a file.

16. The tabbing apparatus of claim 1 , wherein the pocket defines a slit along a top portion for allowing the indexing segment to substantially linearly slide into and out of the pocket between the retracted and extended positions.

17. The tabbing apparatus of claim 16 , wherein the indexing segment is wider than the slit for locking the indexing segment in the extended position.

18. The tabbing apparatus of claim 1 , wherein the tab element comprises a plurality of tab elements such that selected ones of the indexing segments can be positioned in the extended and retracted positions for selectively indexing a file.

19. The tabbing apparatus of claim 1 , wherein the anchor portion is affixed to a wall of the pocket.

20. The tabbing apparatus of claim 7 , wherein:

the tab element has a mid position in which the indexing segment is disposed between the extended and retracted positions, the pocket comprising a resilient member associated with the tab element for biasing the indexing segment away from a mid position toward the extended or retracted position depending on which side of the mid position the indexing segment is positioned;

one of the intermediate segments is hingedly connected to the anchor portion and indexing, segment for pivoting during movement of the indexing segment between the retracted, mid, and extended positions, wherein the pocket has a cross-section that is elongated in depth and has a width, and said one of the intermediate segments biases the resilient member to increase the width of the pocket in the mid position compared to in the retracted and extended positions of the indexing segment; and

the resilient member comprises a resilient wall of the pocket that is flexed by the intermediate segments in the mid position.

21. A tabbing apparatus, comprising:

a pocket; and

a tab element having an indexing segment configured for protruding from the pocket in an extended position as a tab, being received within the pocket in the retracted position, and having a mid position between the retracted and extended positions, wherein the indexing segment is configured for displaying writing thereon for indexing a file;

wherein the pocket comprises a resilient member associated with the tab element for biasing the indexing segment away from the mid position toward the extended or retracted position depending on which side of the mid position the indexing segment is positioned on.

22. A file, comprising:

a first panel having an edge and being configured and dimensioned for holding papers; and

the tabbing apparatus of claim 21 , wherein the pocket is provided on the first panel near the edge such that the indexing segment protrudes beyond the edge in the extended position.

23. The tabbing apparatus of 21 , wherein the tab element in the retracted, mid, and extended position has a substantially U-shape from the indexing segment to the anchor portion when viewed from a lateral cross-section, one of the hinges being at a bottom of the U-shape in each of the said positions.
