Description

[Detailed description of the invention] Industrial field of application The present application relates to a file for storing documents and the like.

BACKGROUND ART Conventionally, two binding pieces made of synthetic resin have been placed in the vertical middle part of the folding part of a cover body which is formed by providing a front cover, a spine cover, a folding part, and a back cover in series. Attach it in an upright position, insert this binding piece into the two holes drilled in the center of the long presser metal fitting,
Moreover, by bending each of the binding pieces and restraining them on the presser metal fittings by two restraining pieces slidably attached to the presser metal fittings, it is possible to create a file called a normal flat file for binding documents, etc. The files used are well known.

Problems that the invention aims to solve By the way, the restraining part in conventional files is made by pressing a thin metal plate in the shape of a horizontal rectangle.
Leaving the left and right side edges and the rear edge, a ridge is formed in the longitudinal direction of the center, which is open at the front end and closed at the rear end.
The left and right side edges of each of the restraining pieces are guided by guide grooves provided on the left and right side edges of the presser fitting so that they can freely slide.

However, the rear edge of the restraint piece is made of a thin metal plate, and there is play between the left and right side edges of the restraint piece and the left and right guide grooves of the presser fitting. While the restraining pieces are sliding on the holding fitting, especially when sliding with force, the trailing edge of one of the restraining pieces may sink into the underside of the other trailing edge, causing A phenomenon occurs in which the edges bite into each other and restrict the sliding movement of the restraining member.

By the way, when inserting a binding piece into a hole drilled in a presser metal fitting, generally, one hand holds one binding piece and the other hand tilts the presser metal fitting to insert the two restraining pieces. While sliding, first open one of the holes and insert one of the binding pieces into the one hole, then tilt the presser metal fitting in the opposite direction to the above and insert the two restraining pieces. The other binding piece is slid to open the other hole of the presser metal fitting, and in this state, the other binding piece is inserted into the other hole.

Therefore, if the sliding movement of the presser metal fitting is restricted due to the rear edges of the two restraining pieces biting together, it may be difficult to insert the binding piece described above into the hole of the presser metal fitting. This has some disadvantages.

Means for Solving the Problems Therefore, the purpose of the present application is to solve the above-mentioned inconveniences by inserting two binding pieces into the two holes provided in the presser metal fitting, and inserting the two binding pieces into the presser metal fitting. By bending the binding pieces in relative directions and restraining them using the two slidably attached restraining pieces, documents, etc., can be secured to the trailing edge of each of the restraining pieces in a bound file. , a protrusion protruding from the surface side is provided, and in the above, the protrusion is provided by bending the rear edge of the restraining piece upward, or The rear edge of the restraining member may be inclined in the width direction, or the trailing edge of the restraining member on one side may be bent in an inverted V shape.

As in the past, after inserting the binding holes of documents etc. into the binding pieces, insert them through the holes provided in the presser metal fittings and place them on the surface of the document, and in this state, The restraining pieces are slid toward the ends of the presser fitting to bend the binding pieces in the relative direction, and the restraining pieces are restrained from being placed on the presser fitting.

Even if the rear edges of the restraining parts are joined together vigorously during handling, the protrusions provided on the rear edges will come into contact and the rear edges will overlap in the vertical direction. There is no risk of the restraining piece being bitten, and therefore the sliding movement of the restraining piece against the holding fitting is maintained smoothly.

In addition, when the protruding part is formed by slanting the rear edge of the restraining part in the width direction, or by bending one side of the trailing edge of the restraining part in an inverted V shape, two restraining parts Even if the pieces have the same configuration, since the protrusions are not directly joined to each other, there is no risk of a biting phenomenon occurring.

Embodiment Hereinafter, the embodiment of the present application will be described in detail based on the drawings. The cover body 1 is made up of a front cover 2, a spine 3, a folding part 4, and a back cover 5. Two binding pieces 6, 6 made of synthetic resin are attached to the portion 4 in an upright state. The elongated presser metal fitting 7 has the binding pieces 6, 6 at its center position.
Holes 8, 8 through which they are inserted, convex stoppers 9, 9, and claw pieces 10, 10 that engage with non-slip portions 6' formed on the inner surfaces of the binding pieces 6, 6 are arranged symmetrically, respectively. Guide grooves 11, 11 are formed on the left and right side edges along the longitudinal direction.

2 that is slidably attached to the presser fitting 7;
The right and left side edges 13, 13 of the restraining pieces 12, 12 are formed by pressing a horizontally rectangular thin metal plate.
and a rear edge part 14, a ridge part 15 is provided in the longitudinal direction of the center thereof, which is open at the front end and closed at the rear end. Each of the 12 rear edges 14 is provided with a protrusion 16 that protrudes toward the front surface.

2 and 3 show a case in which the center portion of the rear edge portion 15 is bent upward and then further folded in half to provide a protruding portion 16.

Then, as in the conventional case, after inserting the binding holes of the document P etc. into the binding pieces 6, 6, the holes 8, 8 provided in the presser metal fitting 7 are inserted, respectively, and this is placed on the surface of the document P. In this state, slide the restraining pieces 12, 12 toward the ends of the holding fitting 7, and remove the binding pieces 6, 12, respectively.
6 in the relative direction, and the restraining pieces 12,
12, it is restrained on the presser fitting 7.

Even if the rear edges of the restraining pieces 12, 12 come together vigorously during handling, the protrusions 16, 16' provided on the rear edges will not come into contact as shown by the phantom lines in FIG. Therefore, their trailing edges do not overlap in the vertical direction.

FIG. 4 further shows a case where the protruding portion 16' is formed in an inverted V-shape toward one side edge of the rear edge portion 14.
FIG. 5 shows a case where the rear edge portion 14 is inclined in the width direction to form a protruding portion 16″.
Even if they have the same configuration, the two restraining pieces 1
2 and 12 are the protruding portions 1 as shown by the imaginary lines in the figure.
Since the 6' and 16'' do not directly contact each other, there is no room for the rear edges of the restraining pieces 12, 12 to overlap in the vertical direction.

Effects Since the present application is constructed as described above, there is no risk that the sliding movement of the restraining piece against the presser fitting will be restricted due to the phenomenon that the trailing edges of the restraining piece bite into each other during handling. Therefore, there is an advantage that the binding piece can be easily inserted into the hole of the presser metal fitting.
