Based on the need of the size of the file folder, the change of the connection board can satisfy the needs of the consumers.
Abstract: A sheet stand which stands a sheet, such as a piece of paper, with a simple operation. The sheet stand includes the sheet stand body 20 and the ball 30. The bottom of the sheet is held between the curved holding surface 21 of the sheet stand body 20 and the ball 30. Then, the ball 30 moves toward the curved surface 24 at the holding surface 21 by its own self-weight, thereby grabbing the bottom of the sheet bending the bottom portion inside to make the sheet firmer to stand.
Abstract: The rings of a loose leaf ring binder are selectively locked and unlocked by a locking member which travels within a slot on the spine of the ring binder. The leaf springs of the loose leaf ring binder have notches formed below a portion of the slot. Therefore, when a W-shaped locking prong of the locking member is aligned with the notches, the leaf springs can freely flex upwardly and downwardly allowing the rings of the loose leaf ring binder to open and close. However, when the W-shaped locking prong is not aligned with the notches, the W-shaped locking prong is urged against the leaf springs thereby maintaining the leaf springs in a downward position thereby locking the rings of the loose leaf ring binder in a closed position. The locking member further includes a locking tab to maintain the locking member within a locked position within the slot.
Abstract: A book holder is disclosed which addresses the unique and heretofore unresolved needs of readers of paperback pocketbooks. In its simplest form, the holder consists of two pieces interlocked so that they are capable of sliding lengthwise in relation to one another. One end of each piece is formed so that when the device is laid upon any flat surface and extended to its most open position, and open paperback pocketbook may be laid face up on top, then the device slid closed to such a position that the formed ends cup over the open pages on opposite sides, thus restraining same for easy viewing. The device includes a detent so as to prevent sliding out of the interlock and falling apart, yet this detent needs be such that it can be overcome with reasonable hand force to allow cleaning or removal of foreign objects.

Abstract: By modification of the design on the U-shaped bracket in previously awarded U.S. Pat. No. 4,628,572, the invention provided a renovated structure for a kind of hinge-typed clipboard which can also equally avoid to use rivets in assembly work. Its elements consist of a board, a supporting base, a clamping element, a torsional spring and a pivotal axle. The distinctive features are that the supporting base is made of metal plate with both sides bent upward and ends rolled up into tube shape. On the board, two transverse groove slots are provided to allow the tube-shaped element of supporting base penetrating through upward from the bottom of the board for combination with clamping element, spring and pivotal axle into an integral clipboard.

Abstract: A holder for sheet material frictionally secures the sheet material intermediate a back plate and a plurality of rollers. A rigid planar plate in converging relationship to the back plate guides the rollers against the back plate to compress the sheet material against the back plate and frictionally retain the sheet material. On exertion upon the sheet material of a pulling force generally in the plane of the back plate, the compressive force will be increased and withdrawal of the sheet material will be prevented. A pulling force exerted upon the sheet material at a substantial angle with respect to the back plate will urge the rollers along the rigid planar plate away from the back plate resulting in removal of the compressive force and permitting release of the sheet material.
