Abstract

A document carrying device has a rigid case formed of upper and lower case halves. The lower and upper case halves are joined together by a hinge wall and lower and upper living hinges. The lower and upper case halves and the hinge wall are complementary to form a substantially closed enclosure when aligned with each other. A ring binder chassis is fixed inside the case to an inner surface of the hinge wall.

Claims

1_9. ] a document carrying device comprising:

a rigid case formed of upper and lower case halves;

the lower and upper case halves joined together by a hinge wall and lower and upper living hinges;

the lower and upper case halves and the hinge wall being complementary to form a substantially closed enclosure when aligned with each other; and

a ring binder chassis fixed inside the case to an inner surface of the hinge wall.

2_9. ] The device of claim 1 with the upper and lower case halves selectively connectable by latches.

3_9. ] A document carrying device comprising:

a rigid case formed of upper and lower case halves;

the lower case half formed of a rectangular lower case half main wall and three lower case half side walls extending perpendicularly from side edges of the lower case half main wall;

the upper case half formed of a rectangular upper case half main wall and three upper case half side walls extending perpendicularly from side edges of the upper case half main wall;

the lower and upper case halves joined together by a hinge wall and lower and upper living hinges;

the lower and upper case half side walls and the hinge wall complementary to form a substantially closed enclosure when aligned with each other; and

a ring binder chassis fixed inside the case to an inner surface of the hinge wall.

4_9. ] The device of claim 3 with at least one of the lower case half side walls having a central section reduced in height relative to the other lower case half side walls in order to permit ease of writing on the lower case half main wall.

5_9. ] A document carrying device comprising:

a rigid case formed of upper and lower case halves;

the lower and upper case halves joined together by a hinge;

the lower and upper case halves and hinge being complementary to form a substantially closed enclosure when aligned with each other; and

a ring binder chassis fixed inside the case to an inner surface of the enclosure; and

at least one page holder formed of flexible plastic and connected to one of the upper or lower case halves, the page holder being provided to hold edges of papers to one of the upper or lower case halves.

6_9. ] The device of claim 5 with a plurality of page holders.

7_9. ] The device of claim 5 with the page holder having a base tab removably retained by a pocket in a wall of one of the upper or lower case halves.

8_9. ] The device claim 5 with the page holder having a U-shaped hold-down portion, the hold-down portion having two side sections and an end section.

9_9. ] The device of claim 6 with the side sections each are curved to have an inner contact area and an outer contact area.

10_9. ] The device of claim 6 with the end section being upwardly bent to enable insertion of one or more paper edges.

11_9. ] The device of claim 5 with the page holder including a central finger provided to hold a writing instrument such as a pen or pencil in a space between the central finger and a hold-down portion of the page holder.

12_9. ] The device of claim 1 with at least one register on one of the lower or upper case halves provided to permit automatic alignment of the upper and lower case halves as they are moved to the closed position, the register engaging a registration portion of the other of the lower or upper case halves.

13_9. ] The device of claim 12 with a plurality of registers and registration portions.

14_9. ] The device of claim 12 with the registration portion being an upstanding registration tab.

15_9. ] The device of claim 3 with at least one register on one of the lower or upper case halves provided to permit automatic alignment of the upper and lower case halves as they are moved to the closed position, the register engaging a registration portion of the other of the lower or upper case halves.

16_9. ] The device of claim 15 with a plurality of registers and registration portions.

17_9. ] The device of claim 16 with the registration portion being an upstanding registration tab.

18_9. ] A document carrying device comprising:

a rigid case formed of upper and lower case halves;

the lower case half formed of a rectangular lower case half main wall and three lower case half side walls extending perpendicularly from side edges of the lower case half main wall;

the upper case half formed of a rectangular upper case half main wall and three upper case half side walls extending perpendicularly from side edges of the upper case half main wall;

the lower and upper case halves joined together by a hinge wall and lower and upper living hinges;

the lower and upper case half side walls and the hinge wall being complementary to form a substantially closed enclosure when aligned with each other;

a ring binder chassis fixed inside the case to an inner surface of the hinge wall;

with the upper and lower case halves selectively connectable by latches along a complementary pair of one of the lower case half side walls and one of the upper case half side walls;

at least one page holder formed of flexible plastic and connected to one of the upper or lower case halves, the page holder being provided to hold edges of papers to one of the upper or lower case halves;

with the page holder having a base tab removably retained by a pocket in a wall of one of the upper or lower case halves;

with the page holder having a U-shaped hold-down portion, the hold-down portion having two side sections and an end section;

with the side sections each are curved to have an inner contact area and an outer contact area;

with the end section being upwardly bent to enable insertion of one or more paper edges;

with the page holder including a central finger provided to hold a writing instrument such as a pen or pencil in a space between the central finger and a hold-down portion of the page holder;

with at least one register on one of the lower or upper case halves provided to permit automatic alignment of the upper and lower case halves as they are moved to the closed position, the register engaging a registration portion of the other of the lower or upper case halves.
