Abstract

A wireless telecommunication device (10) and collapsibly retractable writing surface (50) therefor wherein the wireless telecommunication device includes an outer casing (12) and a collapsibly retractable writing surface (24) which is suitable for receiving and retaining written information thereon. The retractable writing surface (24) has an open position wherein the surface is disposed for receiving and retaining written information thereon and a closed position wherein the surface is fully retracted.

Claims

1. A wireless telecommunication device, comprising:

an outer casing; and

a collapsibly retractable writing surface suitable for receiving and retaining written information thereon, said retractable writing surface having an open position wherein said surface is disposed for receiving and retaining written information thereon and a closed position wherein said surface is fully retracted;

wherein said writing surface comprises a collapsibly foldable writing sheet having a plurality of folds and wherein said writing sheet is substantially flat when said writing sheet is in said open position and said writing sheet is substantially collapsed when said writing sheet is in said closed position;

said collapsibly foldable writing sheet being substantially semicircular, said folds defining generally triangular panels;

wherein said writing sheet is pivotally attached by a pivoting attachment member to said outer casing such that said writing sheet may be pivoted between said open and closed positions by said pivoting attachment member.

2. A wireless telecommunication device in accordance with claim 1 wherein said writing sheet may be fixedly secured into a recess in one side of said outer casing when said writing sheet is in said closed position.

3. A wireless telecommunication device, comprising:

an outer casing; and

a collapsibly retractable writing surface suitable for receiving and retaining written information thereon, said retractable writing surface having an open position wherein said surface is disposed for receiving and retaining written information thereon and a closed position wherein said surface is fully retracted;

wherein said writing surface comprises a collapsibly foldable writing sheet having a plurality of folds and wherein said writing sheet is substantially flat when said writing sheet is in said open position and said writing sheet is substantially collapsed when said writing sheet is in said closed position;

wherein said writing sheet is pivotally attached to said outer casing such that said writing sheet may be pivoted between said open and closed positions; and

further comprising a member having first and second ends, said member being pivotally attached at said first end to said outer casing, said member being substantially attached along its length to an edge of said writing sheet such that rotation of said member about said pivotally attached first end swings said writing sheet between said open and closed positions.

4. A wireless telecommunication device in accordance with claim 3 wherein said second end of said member is detachably connected to said outer casing when said writing surface is in said open position.

5. A wireless telecommunication device, comprising:

an outer casing; and

a collapsibly retractable writing surface suitable for receiving and retaining written information thereon, said retractable writing surface having an open position wherein said surface is disposed for receiving and retaining written information thereon and a closed position wherein said surface is fully retracted;

wherein said writing surface is pivotally attached to said outer casing such that said writing surface may be pivoted between said open and closed positions;

via an integrated pivoting member having first and second ends, said member being pivotally attached at said first end to said outer casing, said member being substantially attached along its length to an edge of said writing sheet such that rotation of said member about said pivotally attached first end swings said writing sheet between said open and closed positions;

wherein said writing surface comprises at least two serially adjoined panels wherein an overlying panel substantially overlies an overlied panel when said writing surface is in said closed position; and

wherein said overlying and overlied panels mutually include guidance means for guiding the relative positions of said overlying and overlied panels.

6. A wireless telecommunication device in accordance with claim 5 wherein said guidance means comprises an alignment pin on one of said serially adjoined panels and a groove within another of said serially adjoined panels.

7. A wireless telecommunication device in accordance with claim 5 wherein said writing surface may be fixedly secured into a recess in one side of said outer casing when said writing surface is in said closed position.

8. A collapsible writing surface for attachment to a wireless telecommunication device having an outer casing, said collapsible writing surface having a closed position wherein said writing surface is fully retracted and an open position wherein said writing surface is fully extended and disposed for receiving and retaining written information thereon, said writing surface comprising:

a series of generally triangular panels mutually constrained for rotational movement at a pivot point of said triangular panels, said panels lying in substantially parallel planes whereby said panels may be rotated between a closed position wherein said panels are generally aligned in a stacked overlying relationship and an open position wherein each of said triangular panels substantially shares one of its edges with an adjacent panel in said series.

9. A wireless telecommunication device, comprising:

an outer casing; and

a collapsibly retractable writing surface suitable for receiving and retaining written information thereon, said retractable writing surface having an open position wherein said surface is disposed for receiving and retaining written information thereon and a closed position wherein said surface is fully retracted;

wherein said writing surface comprises a collapsibly foldable writing sheet and wherein said writing sheet is substantially flat when said writing sheet is in said open position and said writing sheet is substantially collapsed when said writing sheet is in said closed position;

wherein said writing sheet is pivotably attached to said outer casing such that said writing sheet may be pivoted between said open and closed positions by a member having first and second ends, said member being pivotally attached at said first end to said outer casing, said member being substantially attached along its length to an edge of said writing sheet such that rotation of said member about said pivotally attached first end swings said writing sheet between said open and closed positions; and

wherein said writing sheet comprises a plurality of generally triangularly shaped panels having consecutively shared edges, said sheet being collapsibly foldable along said shared edges.
