Description

  The present invention relates to a sheet binding tool that binds sheets such as paper, documents, cards, and bag sheets in which binding holes are formed.

  A sheet binding tool is used to bind sheets such as paper and documents having binding holes. The applicant of the present invention is a sheet binding tool that can spread the bound sheets flat on both sides and can change the width of the binding tool and the back of the file according to the number of sheets to be bound in a state where the file is completely bound. Proposed (see Patent Document 1).

  4A is a development view of a conventional sheet binding tool, and FIG. 4B is a cross-sectional view showing a state in which a file cover is opened.

  In FIG. 4, the sheet binding tool is formed of a single binding plate, and is folded in half on a single binding plate formed of a resilient material with a little elasticity, for example, a synthetic resin such as polypropylene. A binding band plate 1 in which a binding band 6 for passing through a binding hole 18 of a sheet 17 of paper or the like is connected to the edge of the plate is formed on one side with the fold line 4 as a boundary, and on the other side. A binding band locking plate 3 in which a binding band insertion hole 11 for inserting the binding band 6 is formed is formed. Furthermore, a foldable locking portion forming portion 20 is formed in the binding band locking plate 3, and a locking hole 21 for locking the binding band 6 is formed in the locking portion forming portion 20.

  The use method is that the binding band 6 of the sheet binding tool attached to the back cover 16 of the file is passed through the binding hole 18 of the sheet 17 and then passed through the binding band insertion hole 11 of the binding band locking plate 7 and further outward. It latches through the latching hole 21 of the latching part formation part 20 bent.

  When the sheet 17 is opened by moving the binding hole 18 of the sheet 17 to the front cover 19 side or the back cover 16 side along the binding band 6, the sheet 17 can be spread in a planar manner on both sides.

Since the binding band 6 is passed through the binding band insertion hole 11 and the locking hole 21 of the locking portion forming portion 20 bent outward, the binding band is difficult to be removed. Moreover, since the binding band insertion hole 11 and the locking hole 21 are easy to move with respect to the binding band 6, the sheet 17 can be easily spread.
JP 2002-254874 A

  In the binding tool described in Patent Document 1, the binding band 6 is easy to move through the binding band insertion hole 11 and the locking hole 21, and the binding band locking plate 3 is formed of a resilient material having a restoring force. Therefore, even when the binding band locking plate 3 is locked by the binding band 6, the binding band locking plate 3 is lifted upward due to elasticity, and the force for pressing the sheet is weakened, and the sheet is displaced when handling the file. And it was awkward.

  Further, when the cover of the file is opened, the binding band locking plate rises upward due to elasticity, and the locking portion forming portion rises upward, so that the binding tool does not look good.

  Therefore, the present invention provides a sheet binding tool that securely presses the bound sheets and does not stand up when the cover is opened.

  The present invention binds a binding band plate to which a band-like binding band for passing through a binding hole of a sheet such as paper is connected, and a binding band locking plate in which a locking portion for locking through the binding band is formed. In a sheet binding tool formed of a single plate so as to be bendable through a fold at the back of the tool, the binding band has a plurality of stopper protrusions formed in a direction perpendicular to the longitudinal direction of the binding band, and the binding band The locking plate has a binding band insertion hole having a binding band insertion hole for inserting the binding band in the longitudinal direction of the binding band, a stopper portion for locking the binding band, and an opening in which the binding band can be detached from the side. The pressers are sequentially formed in the same row, and the stopper portion between the binding band insertion hole and the binding band presser is formed with a pawl that engages with the stopper projection. The features.

  The stopper claw and the stopper projection move in the forward direction of the binding band. The stopper projection moves over the stopper claw, and the stopper projection engages with the stopper claw in the backward direction to prevent movement. It is formed into a shape. Further, the binding tool back portion has a plurality of trapezoidal holes formed at intervals between the fold line at the boundary with the binding band locking plate and the fold line at the boundary with the binding band locking plate. It is formed of a trapezoidal connection piece, and a back forming fold for bending according to the number of sheets to be bound can be formed on the connection piece.

  In the sheet binding tool of the present invention, since the binding band locking plate is pressed without moving the binding band by the engagement of the stopper projection of the binding band and the pawl of the stopper portion, the binding band locking plate stands up. Therefore, the sheet can be held so as not to be displaced by being pressed by the sheet, and the sheet can be prevented from being misaligned and misaligned when handling the file.

  In the sheet binding tool of the present invention, since the binding band and the binding band locking plate are prevented from moving the binding band by the engagement between the stopper projection of the binding band and the pawl of the stopper portion, the file is opened. However, it is possible to suppress the binding band locking plate from standing upward due to elasticity, and the file binding tool is compactly accommodated, and the appearance is improved compared to the conventional standing binding portion.

  Further, in the sheet binding tool of the present invention, when the sheet is spread, the two binding bands are released from the band locking groove with one touch, and the stopper projection and the stopper portion are disengaged from each other. However, since the binding band insertion hole can be moved backward, the sheet can be easily spread in a planar shape.

  FIG. 1A is a development view of the sheet binding tool of the present invention, and FIG. 1B is a cross-sectional view taken along line AA in FIG. FIG. 2A is a perspective view showing a state where the binding band of the sheet binding tool of the present invention is locked, and FIG. 2B is a cross-sectional view taken along the line BB.

  The sheet binding tool is made of a single synthetic resin plate having elasticity, for example, a synthetic resin plate such as polypropylene. The synthetic resin plate includes a binding band plate 1, a binding tool back portion 2, and a binding band. The stop plate 3 is formed in order through the fold lines 4 and 5. The binding band locking plate 3 is rigid in order to hold the bound sheet, and is reinforced by, for example, reinforcing ribs 22. The fold lines 4 and 5 are formed with a small thickness in order to facilitate folding in two.

  The binding band plate 1 has a pair of binding bands 6 for binding through the binding holes 18 (FIG. 3) of the sheet 17 at intervals between the edges of the binding band plate 1 in a direction perpendicular to the crease 4. Established. On the back surface of the binding band 6, a plurality of saw blade-like stopper projections (indicated by solid lines for explanation) in a direction perpendicular to the longitudinal direction of the binding band 6 to be engaged with the pawl 15 of the stopper portion 12 ) 7 is formed in a wave shape. As shown in FIG. 2, the pawl 15 of the stopper portion 12 and the stopper projection 7 are formed in a ratchet manner, so that the binding band 6 can be easily advanced by moving the stopper projection 7 over the pawl 15 of the stopper portion 12. In the backward direction, the stopper projection 7 is engaged with the pawl 15 of the stopper portion 12 to prevent the movement.

  In this embodiment, the binding tool back portion 2 serving as the back of the sheet binding tool has a plurality of folds 4 between the fold line 4 at the boundary with the binding band locking plate 1 and the fold line 5 at the boundary with the binding band locking plate 3. A trapezoidal hole 8 is formed and a plurality of trapezoidal connection pieces 9 are formed. The crease 5 at the boundary with the binding band locking plate 3 is shortened by making the length of the crease 5 a short side of the trapezoid so that it can be easily folded in order to hold the sheet. Further, the connecting piece 9 may be formed with spine forming folds 10 for folding according to the number of sheets to be bound.

  In the present embodiment, the binding tool back portion 2 is formed with a plurality of trapezoidal connection pieces 9 with gaps 8 provided at intervals. However, the binding band locking plate remains as a plate without any holes. 1 and the fold lines 4 and 5 and the back forming fold line 10 of the binding band locking plate 3 may function in the same manner as in the case of the connecting piece.

  The binding band locking plate 3 is formed with a binding band locking portion for locking the binding band 6 of the binding band plate 1. In the binding band locking portion, a binding band insertion hole 11 for inserting the binding band 6 in the longitudinal direction of the binding band 6, a stopper portion 12 for locking the binding band 6, and a binding band presser 13 for pressing the binding band 6 are arranged in the same row. It forms in order toward an edge. The binding band presser 13 is formed in a bowl shape, and has an opening 14 through which the binding band 6 enters and exits from the side on the side opposite to the side edge.

  A stopper 15 formed between the binding band insertion hole 11 and the binding band presser 13 is formed with a pawl 15 that engages with the stopper projection 7 of the binding band 6. A plurality of pawls 15 are preferably formed. Since the stopper projection 7 and the pawl 15 of the stopper portion 12 are locked in a ratchet manner, when the binding band locking plate 3 is pressed to the sheet side, the binding band 6 is connected to the binding band presser 13 from the binding band insertion hole 11. When the binding band locking plate 3 is about to open, the binding band 6 is prevented from moving in the direction from the binding band presser 13 to the binding band insertion hole 11, and the binding band locking plate 3 can be kept from opening.

  Next, a method for using the sheet binding tool of this embodiment will be described.

  FIG. 3A is a cross-sectional view showing a state where a file cover using the sheet binding tool of the present invention is opened, and FIG. 3B is a perspective view showing a state where the sheet is opened.

  When the sheet binding tool is used for a file, the binding band plate 1 is fixed to the back cover 16 of the opened file by an adhesive or welding.

  When the sheet 17 is bound to the sheet binding tool, the binding band 6 of the binding band plate 1 is passed through the binding hole 18 of the sheet 17 to be bound.

  The binding band 6 through the binding hole 18 of the sheet 17 is inserted into the binding band insertion hole 11 of the binding band locking plate 3. Further, the binding band 6 inserted through the binding band insertion hole 11 is inserted from the opening 14 of the binding band press 13 across the stopper portion 12 and passed through the lower side of the binding band press 13 and pressed.

  After the sheets 17 are bound, when the file cover 19 is bound, the binding band locking plate 3 is pressed and the binding band 6 moves forward, and the stopper protrusion 7 formed on the binding band 6 is the stopper portion 12. To the pawl 15. In this way, the binding band locking plate 3 can hold the sheet 17 so as not to be displaced, so that it is possible to prevent the sheet 17 from being misaligned during handling of the file.

  Further, in a state where the binding band 6 is locked to the binding band locking portion of the binding band locking plate 3, the binding band locking plate 3 remains on the stopper projection 7 of the binding band 6 even if the file is opened. Since the binding band is prevented from moving, the binding band locking plate 3 can be prevented from standing upward due to elasticity. In addition, the file binding tool is compactly accommodated, and the appearance is better than that of a conventional standing binding portion.

  Next, when the sheet 17 is spread in a flat shape, the two binding bands 6 pressed by the binding band press 13 are brought close to each other with the thumb and other fingers so that the two binding bands 6 can be formed with one touch. The binding band presser 13 is disengaged from the opening 14 and the stopper projection 7 of the binding band 6 and the pawl 15 of the stopper 12 are unlocked, so that the binding band 6 can move backward through the binding band insertion hole 11 and the sheet 17 Can be spread easily.
