Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a binding tool effective when binding, for example, computer paper.

Conventional technology and its problems Conventionally, a substrate and a presser made of an elastic material in which a base end portion is tiltably supported by the substrate, a free end portion is engageable with the substrate, and an intermediate portion is bent downward. There is known a binding tool that is configured by a plate and that is configured so that a computer sheet or the like is sandwiched between the substrate and the pressing plate and that binding can be performed on the sheet without forming a binding hole. .

However, according to this configuration, when the elastic force of the pressing plate is increased so that a sufficient clamping force for holding the sheet is obtained,
Large force is required for binding and removing paper,
If these operations become troublesome and a pressing force suitable for binding and removing paper is applied to the holding plate,
The paper gripping force is insufficient, and the paper easily comes off during transportation, and because the paper nipping force varies depending on the thickness of the paper to be bound, the paper easily comes off even when a small amount of paper is bound. Was.

SUMMARY OF THE INVENTION Therefore, the present application utilizes the lever ratio so that the paper can be strongly sandwiched between the pressing member and the substrate even when the number of sheets to be bound is small, thereby eliminating the defects of the conventional ones. It has been resolved.

Hereinafter, embodiments of the present application will be described in detail with reference to the drawings. (1) is a long substrate having an L-shaped cross section, which is made of thin steel plate, leather or synthetic resin at both ends of the horizontal piece (2), and has engaging claws (3), (3) at its tip. A pair of flexible straps each equipped
They are fastened at the rear ends of (4) and (4), respectively. (5) is the substrate
A horizontal piece (2) of the board (1) having a length approximately equal to (1)
A holding member having a narrower width and an upwardly U-shaped cross-section, and the upper end portions of the left and right rising portions of the holding member (5) are curled inwardly on the inner surface of the holding member (5). a is formed. (6) and (6) are pivotally attached (6) a at their outer ends to both ends of the pressing member (5) so that they can be raised and lowered, and are fitted into the pressing member (5) in a laid down state. Cross-section downward U-shaped 1
Use a pair of operating levers to move the band in the longitudinal direction of the upper surface.
Engagement holes (7) ... (7) ... are provided in which the engaging claws (3) and (3) of (4) and (4) are selectively engaged, respectively. ing.
(8) and (8) are provided at both ends of the pressing member (5), and the stop band (4) and (4) are in sliding contact with each other in a use state,
(9) is a rib bent upward along the side edge of the horizontal piece (2) of the substrate (1), and (10) and (10) are slidably engaged in the holding member (5). A pair of restraining members for holding the operating levers (6) and (6) in the laid-down state. The restraining members have a downwardly U-shaped cross section, and the left and right lower ends thereof are further bent outward so that the pressing member ( Suppressing portions (11) and (11) that slidably engage with the engaging groove (5) a of 5) and that restrain the free ends of the operating levers (6) and (6) from the upper surface at one end. Are projected integrally with each other.

The binding device configured in this way is provided with a substrate (1) at a position near the back cover b of the back cover c of a cover member A formed by, for example, connecting a front cover a, a back cover b, and a back cover c in series. The horizontal piece (2) is fixed by, for example, a stopper to form a binder.

When binding the paper p to the binder, the side edge of the paper p to be bound is placed on the horizontal piece (2) of the substrate (1) with the pressing member (5) removed from the substrate (1). ), Then the pressing member (5) is placed on the upper surface of the side edge of the paper p, and the operation levers (6) and (6) are erected so that the stop band (4),
The engaging claws (3) and (3) of (4) are selectively engaged with arbitrary engaging holes (7) and (7), respectively. After that, from this state, the operation lever
When the (6) and (6) are laid down, the stop bands (4) and (4) are separated from the distance between the pivoting portion (6) a of the operating lever (6) and the end surface of the sliding contact piece (8), It is indexed according to the ratio of the distance between the pivoting portion (6) a of the operating lever (6) and the engaging portion of the stop band (4), and downward force is also applied to the pivoting portion (6) a. Then, the pressing member (5) is strongly pressed downward,
Therefore, the paper p is strongly held on the substrate (1) by the pressing member (5). In this state, the restraining members (10) and (10) are slid respectively to restrain the free ends of the operation levers (6) and (6) by the restraining portion (11).

Also, from this sandwiched state, the restraining members (10), (10) slide in opposite directions to separate the restraining portion (11) from the free end portion of the operating lever (6), and then the pushing portion of the operating lever (6). (6) Press b upward to raise the operating lever (6). In this case the stop band (4),
Since the force in the upright direction acts on the operation levers (6) and (6) via (4), the upright operation of the operation lever (6) can be easily performed.

FIG. 5 shows another embodiment of the present application. The difference from the first embodiment is that the engaging projections (12), (12) are provided on one side surface of the free end of the pressing member (5). The pivot shafts (13) protruding from each other and pivotally connecting the pressing member (5) and the operation levers (6) and (6) are attached to the operation levers (6) and (6) when the operation levers (6) and (6) are folded down. Due to the indexing force acting on the bands (4) and (4), the operating levers (6) and (6) are inclined in one lateral direction with respect to the holding member (5), and the engaging protrusions (12) and (12) ) Are tilted so as to be respectively locked in the engaging grooves (5) a, so that the restraining member (1) for holding the operation levers (6), (6) in the laid-down state.
The point is that (0) and (10) are omitted.

When the operation levers (6) and (6) are turned down,
(6) and (6) lie down with respect to the pressing member (5) in a slightly inclined state, but at the time of the laying down, the free ends of the operation levers (6) and (6) move in the direction opposite to the inclined direction. By pressing the
2) and 12 are engaged with one engaging groove 5a formed in the pressing member 5, so that the operation levers 6 and 6 are kept in the down state. .

EFFECTS OF THE INVENTION As described above, according to the present application, since the pressing member is pressed against the substrate by utilizing the lever ratio, the engaging claw can be selectively inserted into the engaging hole even when the paper to be pinched is small. By engaging, it has an advantage that it can be held with a strong clamping force, and the structure is simple and the handling is easy.
