Description

The present invention relates to a clipboard having a plurality of holding pieces.

When a piece of paper is sandwiched and fixed to a clipboard provided with a paper fixing clipboard only at the top of the clipboard, the piece of paper is not fixed at the bottom, so that the piece of paper is fixed to this clipboard at the bottom. There is a problem that the piece of paper is folded or curled when the piece of paper is lifted, and in order to solve such a problem, a clipboard provided with a paper fixing clip portion at the bottom is known (Patent Document 1).

Japanese Unexamined Patent Publication No. 11-157269

In such a clipboard, the upper paper fixing clip part sandwiches and fixes the upper part of the paper piece, and the lower fixing clip part sandwiches and fixes the lower part of the paper piece, so that the lower part of the paper piece is prevented from floating, and further, these If the clip portion is formed of a holding tool consisting of a presser foot rotatably provided with respect to the substrate and an urging means for urging the presser foot to press the substrate, the clip portion is made of paper. It has a strong fixing force and can be used upside down.

Further, the upper paper fixing clip portion is formed by a holding tool provided with a presser foot and an urging means, and the lower fixing clip portion is provided on an elastic plate material integrally molded with the substrate and a tip thereof. If it is formed by a pressing portion that sandwiches and presses a piece of paper placed on the substrate, the former has a strong fixing force of the paper to the substrate, and the latter has a weak fixing force of the paper. Since the paper can be easily fixed by simply inserting the paper clip between the substrate and the pressing part, such a clipboard is used for the upper paper in a usage mode in which the paper piece is fixed at the upper part and the paper piece is inserted / removed at the lower part. Both the fixed clip portion and the lower fixed clip portion are more convenient than those formed by a holding tool provided with a holding tool and a urging means.

However, both of these clipboards are common in that one end and the other end of a piece of paper placed on the board are sandwiched by the respective clip portions to fix the piece of paper, and the piece of paper is securely fixed to the board. It is highly convenient for the purpose of It is necessary to repeat the operation for fixing and the operation for opening in the paper fixing clip portion of the above, which is not very convenient.

Further, a plurality of pieces of paper were placed on the clipboard, these were sandwiched by the clipboard, and the first piece of paper was rolled up and placed at a position closer to the substrate than the position where the first piece of paper was placed. When the second piece of paper is exposed and the user acts such as looking at the characters or figures written on the second piece of paper or writing something on it, the first piece of paper is maintained in a rolled state. However, if the clipboard does not have the means to keep the piece of paper rolled up, the user must continue to hold the first piece of paper with his or her fingers or the like. However, their actions will be severely restricted.

Further, in such a usage pattern, when the first piece of paper unintentionally returns to the state where it overlaps with the second piece of paper, the first piece of paper is partially placed on one of the paper fixing clips. In such a state, the first piece of paper may be broken or torn by receiving an external force such as the user's finger hitting the piece of paper.

An object of the present invention is to provide a clipboard that solves these problems.

The clipboard of the present invention has a base for attaching to one end of one surface of a substrate, a main holding piece rotatably provided with respect to the base, and an urging to press the main holding piece against the base. A clipboard provided with a main holding tool comprising a force means and a main holding tool, which is rotatably provided on the other surface of the substrate, which is a surface opposite to the one surface, and is in contact with the substrate. It has a directionally urged other side clipboard.

The other-side holding tool has a other-side fixing piece and another-side holding piece rotatably connected to the other-side fixing piece via a hinge portion, and the other-side fixing piece is the other side of the substrate. By being attached to the other side holding piece, the other surface holding piece is rotatably arranged with respect to the substrate.

For example, a magnetic material having a polar relationship that attracts each other is embedded in the substrate and the other-side holding piece of the other-side holding tool, or either the substrate or the other-sided holding tool has a magnetic material embedded in one of them and the other. A metal piece having a property of being attracted to the magnetic material is embedded in the substrate, so that a magnetic force is generated between the substrate and the other surface holding tool in the direction in which they are in contact with each other.

By forming the other-side holding tool in this way, the paper piece placed on the substrate is held by the main holding tool, the paper piece is rolled up and brought into contact with the other surface of the substrate, and the paper piece is magnetically pressed. It can be stopped by sandwiching it between the board and the other side holding tool.

It consists of a base for attaching to one end of one surface of the substrate, a main holding piece rotatably provided with respect to the base, and an urging means for urging the main holding piece to press the base. A clipboard provided with a main holding tool, which is rotatably provided with respect to the substrate on the other surface, which is a surface opposite to the one surface of the substrate, and is urged in a direction in contact with the substrate. The other- side holding tool has the other-sided holding tool, and the other-sided holding tool includes a other-sided rotating piece rotatably provided with respect to the substrate and another-sided holding piece connected to the other-sided rotating piece. , Have.

That is, in the other-side holding tool, the other-side rotating piece and the other-side holding piece are connected in succession via a folding line, in other words, between the hinge portion of the other-side fixing piece and the other-side holding piece. By providing the surface rotating piece, the other surface rotating piece is rotated to stand upright or tilted with respect to the substrate according to the thickness of the paper piece group to be sandwiched, and the other surface holding piece and the substrate are provided. By bending the other side holding piece with respect to the other side rotating piece at the position of the folding line so that the other side holding pieces are substantially parallel to each other, a separation corresponding to the thickness of the paper piece group is created between the substrate and the other side holding piece. Can be provided.

The tip of the other-side holding piece is a finger inclined in a direction away from the substrate from the hinge portion of the other-side fixing piece toward the tip portion in a state where the other-side holding tool is in contact with the other surface of the substrate. It has a hinged part.

When such a finger rest inclined portion is provided, even if the other surface holding tool is in close contact with and fixed to the substrate by a strong magnetic force, the tip portion is between the other surface holding piece and the substrate. Since there is always a gap, the user can easily lift the other-side holding tool from the board by hanging his or her fingers or the like in the gap.

It consists of a base for attaching to one end of one surface of the substrate, a main holding piece rotatably provided with respect to the base, and an urging means for urging the main holding piece to press the base. A clipboard provided with a main holding tool, which is rotatably provided with respect to the substrate on the other surface, which is a surface opposite to the one surface of the substrate, and is urged in a direction in contact with the substrate. It has an other- side holding tool and is rotatably provided at the other end of the substrate at a position facing the one end, and is polymerized on the one surface of the substrate and on the other surface of the substrate. It has a second position to be polymerized and an auxiliary clipboard formed so that either one can be selected.

The sub-holding tool has a sub-fixing piece fixed to the substrate and a sub-holding piece rotatably connected to the sub-fixing piece.

For example, a magnetic material having a polar relationship that attracts each other is embedded in the holding portion of the substrate and the auxiliary holding tool, or a magnetic material is embedded in one of the substrate and the auxiliary holding tool, and the magnetic force is applied to the other. By embedding a metal that has the property of being attracted to the body, a magnetic force is generated between the substrate and the auxiliary holding tool in the direction in which they come into contact with each other.

Further, in order to selectively realize the first fixed position and the second fixed position, the auxiliary holding tool needs to be formed so as to be rotatable approximately 360 ° with respect to the substrate. ..

In order to realize this, a bendable piece is provided between the sub-fixed piece and the sub-holding piece, and the bent piece extends from the sub-fixed piece fixed to the other surface of the substrate. , The sub-sandwich piece is positioned so as to polymerize with the sub-fixed piece on the other surface of the substrate, and the sub-sandwich piece is positioned so as to polymerize on one surface of the substrate. ..

With such a configuration, the clipboard of the present invention has a plurality of pieces of paper placed on one end of one surface of the substrate by a main holding tool, and the first piece of paper is rolled up to hold the first piece of paper. The second piece of paper placed closer to the board than the position where the piece of paper was placed is exposed, and the user sees the characters and figures written on the second piece of paper or puts something on it. Since the first piece of paper can be sandwiched between the substrate and the other side holding tool on the other surface of the substrate when writing or writing, the first piece of paper is maintained in a rolled state. In such a case, the user does not need to keep holding the first piece of paper with his / her own fingers or the like.

Further, in the clipboard of the present invention, in a state where a piece of paper is sandwiched by a main holding tool at one end of one surface of a substrate, a piece of paper is sandwiched at the other end of one surface of the piece of paper with the secondary holding tool as the first position, and the piece of paper is used as a substrate. On the other hand, depending on the usage mode in which the operation of firmly holding each piece of paper and repeating the operation of rolling and returning each piece of paper to the stacked state, the auxiliary holding tool is set as a second position that does not come into contact with the piece of paper on one side. It is possible to select to open the piece of paper at the other end.

It is a perspective view of the clipboard which held a piece of paper by the main holding tool. It is a perspective view of the clipboard in a state where the sandwiched piece of paper is rolled up and fixed on the other surface of the substrate. It is a right side view of the clipboard in a state where the sandwiched piece of paper is rolled up and fixed on the other side of the substrate. It is an enlarged right side view which shows the neighborhood of the other surface holding tool. It is a perspective view of the clipboard which held a piece of paper by a main holding tool and a secondary holding tool. It is an enlarged right side view which shows the neighborhood of a secondary holding tool. It is a perspective view which shows the state in which the vicinity of the main holding tool of a piece of paper held by a clipboard is rolled up. It is a perspective view of the clipboard provided with the paper piece fixative. It is a rear view of the clipboard.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present specification, unless otherwise specified, the vertical direction visually recognized in FIG. 9 is referred to as the "vertical direction of the clipboard", and the left-right direction visually recognized is referred to as the "left-right direction of the clipboard".

The clipboard 1 shown in FIG. 1 has a main holding tool 3 composed of a base 31 and a main holding piece 33 rotatably and urged in a direction in contact with the base 31 at an upper end of one end of the substrate 2. A wedge-shaped mounting portion 34 is attached by penetrating the substrate 2 and the base portion 31 so that one surface 21 and the base portion 31 are in contact with each other, and the paper piece 4 has a paper piece 4 whose upper end is the base portion 31 and the main holding piece 33. When it is placed on one surface 21 of the substrate 2 so as to be located between and, it is sandwiched between the base portion 31 and the main sandwiching piece 33 by the urging force of the main sandwiching piece 33.

In a state where the upper end of the paper piece 4 is sandwiched by the main holding tool 3 with respect to such a clipboard 1, as shown in FIG. 2, the first paper piece 4 is rolled up and the first paper piece 4 is placed. The second piece of paper 4 placed closer to the board than the clipboard is exposed, and the other end, that is, the lower end, which is the end facing the upper end of the first piece of paper 4, is the other surface 22 of the board 2. It can be sandwiched by the other-side clipboard 5, which will be described later.

More specifically, as shown in FIG. 3, in a state where the upper end of the first piece of paper 4 is sandwiched by the main holding tool 3, the first piece of paper 4 straddles the main holding tool 3 and its lower end and its lower end thereof. A near portion is located between the other surface 22 of the substrate 2 and the other surface holding tool 5, and is in contact with the other surface 22 of the substrate 2, and the portion is generated between the substrate 2 and the other surface holding tool 5. The paper pieces 4 are fixed on the other surface 22 of the substrate 2 by being sandwiched by the urging forces in the directions in contact with each other.

As shown in FIG. 4A, in the other-side holding tool 5, the other-side holding piece 51 and the other-side fixing piece 55 are rotatably connected to each other via the hinge portion 54, and the other-side fixing piece 5 is connected. By fixing 55 to the other surface 22 of the substrate 2, the other surface holding piece 51 becomes rotatable with respect to the substrate 2, for example, although not shown, the substrate 2 and the other surface holding piece 51 A metal having a polar relationship that attracts each other is embedded in the metal, or a metal having a property that one of the substrate 2 and the other surface holding piece 51 has a magnetic material embedded in one and the other has a property of being attracted to the magnetic material. When the pieces are embedded, a magnetic force is generated between the substrate 2 and the other surface holding piece 51 in the direction in which they are in contact with each other.

By the way, in order to stably fix the paper piece 4 on the other surface 22 of the substrate 2, it is preferable that the other surface holding piece 51 and the substrate 2 are in a parallel positional relationship, which is shown in FIG. 4A. In the configuration, when a large amount of paper pieces 4 are rolled up and fixed on the other surface 22 of the substrate 2, the other surface holding piece 51 stands upright with respect to the substrate 2.

Therefore, according to such an application, as shown in FIG. 4B, in the other surface holding tool 5, the other surface rotating piece 53 and the other surface fixing piece 55 rotate with each other via the hinge portion 54. In addition to being movably connected, the other-side holding piece 51 and the other-side rotating piece 53 may be rotatably connected to each other via the folding line 52.

With such a configuration, when a large amount of paper pieces 4 are rolled up and stopped on the other side of the substrate,
The other side rotating piece 53 is rotated to stand upright or tilted with respect to the substrate 2 according to the number / thickness of the paper pieces 4 to be sandwiched, and the other surface holding piece 51 and the substrate 2 are substantially parallel to each other. By bending the other-side holding piece 51 with respect to the other-side rotating piece 53 at the position of the folding line 52 so as to be, it corresponds to the number / thickness of the paper pieces 4 between the substrate 2 and the other-side holding piece 51. It is possible to provide a separation.

Next, the clipboard 1 shown in FIG. 5 will be described. The description of the same configuration as that of the clipboard 1 shown in FIG. 1 will be omitted.

In such a clipboard 1, a sub-pinching tool 6 is rotatably provided at the lower end of the substrate 2 provided with the main pinching tool 3 with respect to the substrate 2, and a piece of paper 4 is placed on the clipboard 1. The sub-pinching tool 6 can pinch the lower end of the paper piece 4 in a state where the upper end thereof is pinched by the main pinching tool 3.

As shown in FIG. 6, the sub-holding tool 6 has a bending piece 62 in which the sub-holding piece 61 and the sub-fixing piece 63 for holding the paper piece 4 between itself and the substrate 2 are flexibly formed. The sub-fixing piece 63 is fixed to the other surface 22 of the substrate 2 and the bent piece 62 is bent so that the holding piece 61 is polymerized on the one surface 21 of the substrate 2. , A second position to be polymerized on the other surface 22 of the substrate 2 via the sub-fixing piece 63, is formed so as to be selectable. If it is assumed that the number of paper pieces 4 to be placed is large, a large bending piece 62 may be used, and if it is assumed that the amount of paper pieces 4 to be placed is small, the bending piece 62 may be used. A smaller one may be adopted, and further, instead of the bent piece 62, the holding piece 61 and the sub-fixing piece 63 may be continuously provided via a hinge or a folding wire.

FIG. 6A shows a state in which the paper piece 4 is placed on one side 21 of the substrate 2 and the sub-holding piece 61 is in the second position. In this state, since the paper piece 4 is not sandwiched at the lower end of the substrate 2, if the upper end of the paper piece 4 is sandwiched by the main holding tool 3, the paper piece 4 can be freely rolled up while being bound to the clipboard 1. It can be moved back and forth.

For example, although not shown, a magnetic material having a polar relationship that attracts each other is embedded in the substrate 2 and the sub-pinching piece 61, or a magnetic material is embedded in either the substrate 2 or the sub-pinching piece 61. On the other hand, a metal piece having a property of being attracted to the magnetic material is embedded in the other, so that a magnetic force in a direction in which the substrate 2 and the auxiliary holding piece 61 are in contact with each other is generated.

If the substrate 2 and the sub-pinching piece 61 are formed in this way, the sub-pinching piece 61 is fixed to the other surface 22 of the substrate 2 by the magnetic force thereof, so that the sub-pinching piece 61 binds the paper piece 4 to the clipboard 1. It is suitable because it does not hinder the free turning and unwinding in the state of being held, but it is limited to such a configuration as long as the auxiliary holding piece 61 can be fixed to the other surface 22 of the substrate 2. It is not necessary, and both may be configured to engage with each other in a removable manner such as a hook-and-loop fastener.

In order to sandwich the lower end of the paper piece 4 between the substrate 2 and the sub-pinching piece 61 from the state shown in FIG. 6A, the sub-pinching piece 61 is fixed to the other surface 22 of the substrate 2 from the state where the sub-pinching piece 61 is fixed to the other surface 22 of the substrate 2. The state shown in FIG. 6 (b) in which the sub-holding piece 61 is not fixed to the board 2 by pulling the sub-holding piece 61 away from the other surface 22 of the board 2 with the user's fingers or the like to release the fixed state. The sub-pinching piece 61 may be moved toward the position facing the surface 21 of the substrate 2 and the sub-pinching piece 61 may be fixed at the first position shown in FIG. 6 (c).

As described above, if a magnetic material or a metal piece is embedded in the substrate 2 and the sub-pinching piece 61, the magnetic force generated between the two passes through the paper piece 4 placed on one surface 21 of the substrate 2. By this force, the paper piece 4 is sandwiched between the substrate 2 and the sub-pinching piece 61.

By the way, depending on the material of the paper piece 4, in the vicinity of the main holding tool 3 so as to repeat the operation of rolling and returning the paper pieces 4 placed on the substrate 2 and held by the main holding tool 3 to the stacked state. At the point, when the rolled state is irreversible, that is, a state with a'rolling'is attached, and the main holding tool 3 continues to be held in that state, as shown in FIG. 7, the paper piece 4 It is conceivable that the paper piece 4 is maintained in a raised state with respect to the substrate 2 due to'rolling'at both ends in the left-right direction in the vicinity of the main holding tool 3.

If such a state is left unattended, the user's finger may hit the raised portion, which may cause a problem that the paper piece 4 is broken or torn.

Therefore, as shown in FIG. 8, the main holding piece 33 has the same or the same length as the paper piece 4 in the left-right direction so that such four sides can be held at the upper end and its vicinity over the entire length in the left-right direction. A slightly long main holding piece auxiliary tool 35 may be attached, or, although not shown, the length of the main holding piece 33 in the left-right direction may be the same as or slightly longer than the length of the paper piece 4 in the left-right direction.

As shown in FIG. 9, the mounting portion 34 penetrating the substrate 2 and the base 31 appears on the other surface 22 of the substrate, and the other surface fixing piece 55 is fixed to the other surface 22 of the substrate 2 via the hinge 54. Further, if the configuration has the other surface rotating piece 53 and the folding line 52, the other surface holding piece 51 is rotatably formed with respect to the substrate 2 through them.

Further, the length of the other side holding piece 51 in the vertical direction is such that the upper end of the paper piece 4 is sandwiched by the main holding tool 3 and is rolled so as to straddle the main holding tool 3, and the lower end thereof and the portion in the vicinity thereof are formed. If the lower end of the piece of paper 4 in such a state is reached in contact with the other surface 22 of the substrate 2, the length of the other surface holding tool 5 in the left-right direction is the length of the substrate 2 as visually recognized in FIG. The length in the left-right direction is not limited to substantially the same as the length in the left-right direction, and a suitable length may be adopted according to the assumed size and amount of the piece of paper 4.

The length of the auxiliary holding tool 6 in the left-right direction is set to be slightly shorter than that of the substrate 2, whereby the auxiliary fixing tool 6 is formed so that each side end except the lower end is surrounded by the other side fixing piece 55. However, with such a configuration, if the thickness of the other side fixing piece 55 is the same as or slightly thicker than that of the sub-fixing piece 61, the sub-fixing piece 61 is the second. It is possible to prevent the user's fingers from touching and unintentionally moving away from the second position in the state of being in the position, but it is not necessary to be limited to such a configuration, and the auxiliary holding tool 6 is in the left-right direction. The length of the substrate 2 may be substantially the same as that of the substrate 2, and may be formed so that the upper end of the sub-fixing piece 61 and the lower end of the other surface fixing piece 55 face each other.
