Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a staple removing tool for easily removing staples stapling a document or staples of a packaging bag enclosing components without damaging them.

2. Description of the Related Art Conventionally, staple removing tools for removing staples of a document or staples of a packaging bag in which parts and the like are enclosed are
A spatula that intervenes between the staple and the document or the packaging bag is attached to the tip of the long and tapered gripping member, and the upper surface of the spatula is parallel to the staple with the elastic plate removed at the required interval. The elastic plate is provided with a joining projection that abuts against the surface of the spatula in the lower surface of the tip of the elastic plate. The staple is inserted between the spatula part and the elastic part by inserting it in between, and the staple part is pulled out by tilting the spatula part upward and the staple thus extracted is separated from the spatula part and the elastic plate. It is something to hold during.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, according to the above-described conventional staple removing tool, when discharging the staples retained between the spatula portion and the elastic plate, it is necessary to perform a troublesome work of pulling out the staples by a hand or the like. Not only that, but there were defects such as scratches on the hands due to staples during the work.

Therefore, in order to solve the above-mentioned defects, the present application proposes, on the joining surface, a convex portion that continuously comes in contact with the surface of the substrate, which will be described later, from the front end portion of the joining surface, and a horizontal depression. A gripping member formed by joining an upper gripping piece made of synthetic resin, in which a recessed surface, a ridge having an inclined surface in the rearward direction, and a recessed portion are sequentially formed, to the lower gripping piece, and joining of the lower gripping piece A substrate made of a steel plate that is fixed to the surface and has a tip spatula projecting from the tip of the gripping member, and is inserted in the recessed portion so as to be movable back and forth, and is press-fitted between the ridge and the substrate during forward movement. The present invention provides a staple removing tool characterized in that it comprises an externally operable wedge part that presses the front part of the upper gripping piece upward, and preferably, the gripping member is provided on both sides of the recessed portion position. The surface of the wedge has a depression, and the wedge piece A flange piece facing the inside of the hollow portion is provided at both ends of the rearwardly movable shaft portion, and a wedge piece is integrally provided on the front surface of the shaft portion.

However, when the document is closed and the staples are removed using the removing tool of the present application, the gripping member is gripped while the wedge piece is slid backward, and the lower surface of the front end of the lower gripping piece is brought into contact with the document surface. Then, the spatula of the board is pushed forward while inserting the spatula between the document and the staple.

Then, the staple pushes up the convex portion to enter the gap, and when the gripping member is tilted upward, the staple is extracted and retained in the gap.

When the staples retained in the gap are discharged in this way, the wedge piece is slid forward by an external operation. Then, the wedge piece is press-fitted between the ridge and the substrate, the front part of the upper gripping piece bends upward, and the convex part separates from the board by this, so that the gripping member stands upright. The staple held in the gap can be discharged from between the convex portion and the substrate.

Example Hereinafter, an example of the present application will be described in detail with reference to the drawings.
(1) is an elongated gripping member made of synthetic resin, which is formed by vertically joining an upper sliding piece (1) a and a lower gripping piece (1) b having substantially the same shape. The upper gripping piece (1) a is , The joint surface is a flat and tapered piece, and the convex portion (2) continuously abutting from the front half of the joint surface on the rear surface of the substrate (13) described later, and the rear portion thereof. (3) with a concave surface that is horizontally depressed in
And a hill portion (5) having an inclined surface (4) on the rear side, and a recessed portion (6) which is continuously recessed horizontally in the rearward direction, and the recessed portion (6) is formed. ), Notches and recesses (7) are provided on both side surfaces, and engaging holes (8) are provided at the front and rear positions of the joining surface. The lower gripping piece (1) b is also composed of a taper-shaped piece whose joint surface is flat, and the front half of the joint surface conforms to the shape of the substrate (13) described later,
Moreover, a concave surface (10) corresponding to its thickness is formed, and a shaft pin (11) engaging with the engaging hole (8) is provided at the front and rear positions so as to project. Further, on both side surfaces, a cutout recess (12) is provided which matches the cutout recess (7) when joined to the upper gripping piece (1) a. (13)
Is a base plate made of a steel plate fitted in the concave surface (10) and having a spatula portion (14) protruding from the tip of the lower gripping piece (1) b at the front end, and the front shaft pin ( There is a hole (15) through which 11) is inserted. Reference numeral (16) is a wedge piece made of synthetic resin, and a shaft (1
Collar pieces (1) facing the inside of the notches (7) and (12) at both ends of (7)
8) and has a triangular wedge piece (1
9) is projected.

Then, the substrate (13) is attached to the concave surface (10) of the lower gripping piece (1) b.
And the spatula portion (14) is projected from the tip of the lower gripping piece (1) b, and the shaft portion (16) of the wedge piece (16) is inserted into the concave portion (6) of the upper gripping piece (1) a. Both gripping pieces (1) a and (1) b are integrally joined by an adhesive or a set screw with the interposition of 17).

In this joined state, the shaft pin (11) is fitted into the engagement hole (8), the spatula portion (14) projects from the tip of the gripping member (1), and the collar piece (18) is provided with the cutout portion (7). ), (8), the convex portion (2) abuts on the surface of the substrate (13), and the recessed surface (3) causes a gap between the upper gripping piece (1) a and the substrate (13). A gap (20) is formed.

For example, when the staple A that closes a document is removed using the removing tool of the present invention configured as above, the wedge member (16) is slid backward and the gripping member (1) is gripped to lower the lower part. The lower surface of the front end of the gripping piece (1) b is brought into contact with the document surface, and the spatula portion (14) of the substrate (13) is pushed forward while inserting it between the document and the staple A.

Then, when the staple A pushes up the convex portion (2) and enters the gap (20) and then the gripping member (1) is tilted upward, the staple A is extracted and retained in the gap (20). It

The staple A retained in the gap (20) in this way
When discharging, hold the collar piece (18) and wedge piece (16).
Slide forward. Then, the wedge piece (19) becomes a hill (5).
And the substrate (13) are press-fitted, and the front part of the upper gripping piece (1) a is bent upward, so that the convex portion (2) becomes the substrate (1).
Since it is separated from 3), the staple A held in the gap (20) can be discharged from between the convex portion (2) and the substrate (13) by standing the gripping member (1) vertically. .

EFFECTS OF THE INVENTION As described above, according to the present application, the staples extracted can be retained between the substrate and the front portion of the upper gripping piece, and the retained staples have the convex portions abutting on the substrate surface. This has the advantage that the staples can be easily ejected without being damaged by the external operation of the wedge piece, and that the staples can be easily ejected without being damaged.
