Description

[Detailed description of the invention] This invention relates to a rotating binding metal fitting. In order to stitch documents into files, rotary binding fittings are widely used in which documents are inserted and removed by rotating a rotating plate with a binding rod attached, but conventional binding fittings have a complicated structure. What's more, the rotating plate was not properly locked after the file was inserted.

This invention improves the conventional rotating binding metal fitting to obtain a rotating binding metal fitting that is simple in structure and has a perfect locking of the rotating plate.

To explain the figures, FIGS. 4 to 8 show an example of a conventional rotating binding metal fitting. FIG. 4 is a perspective view of the binding metal fitting 50 when it is closed, and FIG. 6 is a view showing the bottom plate 5, FIG. 7 is a view showing the sliding plate 6, and FIG. 8 is a view showing the rotating plate 7 to which the spelling rod is attached. This binding fitting 50 is composed of three parts: a bottom plate 5, a sliding plate 6, and a rotating plate 7 to which binding rods 72, . . . are attached. The bottom plate 5 has a number of teeth 52, . Furthermore, multiple (2 in the figure)
T-shaped cut and raised pieces 54 are provided. Attachment portions 56, 56 for attaching the rotating plate 7 are formed at both ends of the plate main body 51 by bending or the like. Then, the mounting holes 56' are drilled, and the mounting protrusions 76 (see FIG. 8) protruding from both ends of the rotating plate 7 are fitted into the mounting holes 56', and the rotating plate 7 is attached to the bottom plate 5. Figure 5).

The sliding plate 6 has one end of the plate main body 61 bent to form a finger rest 62, and cut and raised engaging pieces 63, 63 on the left and right sides.
is provided. The upper part of this engaging piece 63 serves as an engaging protrusion 63'. Further, there is a cut-and-raised engagement piece 65 in the center, and on the left and right sides thereof, T-shaped holes 64 from which the cut-and-raised pieces 54 of the bottom plate 5 protrude upward,
64 is open.

The rotating plate 7 has a large number of spelling rods 72, .
75, left and right notches 74, 74, and center notch 74
exists. The left and right protrusions 73, 73 are provided with a protrusion 73' that engages with an engagement protrusion 63' of the sliding plate 6, as will be described later.

As shown in FIG. 5, a sliding plate 6 is placed on the bottom plate 5.
The rotating plate 7 has mounting protrusions 7 on both ends.
6 are attached to the bottom plate 5 by passing them through the holes 56' of the mounting portions 56 at both ends of the bottom plate 5. Since the T-shaped cut-and-raised piece 54 provided on the bottom plate 5 is combined so as to protrude above the T-shaped hole 64 of the sliding plate 6, it can be slid from side to side by the hole 64 of the sliding plate 6. Furthermore, the T-shaped cut-and-raised piece 54 prevents the sliding plate from separating from the bottom plate.

Figure 5 shows the sliding plate 6 pulled to the left to open the rotating plate 7 (therefore the spelling rods 72,...). If you turn the rotating plate 7 onto the bottom plate 5 and push the sliding plate 6 to the right using the finger hook 62,
The cut and raised pieces 63 and 65 fit into the edges of the protrusions 73 and 75, respectively, and lock the rotating plate 7. At this time, the engaging protrusion 63' of the cut and raised piece 63 engages with the engaging protrusion 73' on the edge of the protrusion 73. When opening the binding tool, pull the sliding plate 6 to the left to return to the state shown in FIG. becomes.

This conventional binding tool has a complicated structure, and there is a risk that the binding tool will open if some force is applied to the finger hook 62, etc., and the locking tool is not reliable.

This invention eliminates the drawbacks of the conventional rotating binding device. Figure 1 is a perspective view of the rotating binding device of this invention when it is closed, Figure 2 is a view showing the bottom plate, and Figure 3 is a diagram showing the bottom plate. It is a figure showing a rotating plate, and the rotating binding metal fitting 10 of this invention consists of a bottom plate 2 and a rotating plate 3, and the rotating plate 3 is rotatably attached to the bottom plate by a core rod 4.

The front edge of the plate main body 21 of the bottom plate 2 has a bent portion 22 for reinforcement. Also, several core rod attachment portions 23 are formed on the rear edge. Further, the plate main body 21 is provided with a plurality of cut and raised pieces 24, and the ends thereof are bent to form an upright piece 25 and an end bent portion 2.
6 is formed.

As shown in FIG. 3, the rotating plate 3 is provided with a large number of spelling rods 32, . One end is bent upward to form an upright portion 35, to which a locking body 36 is rotatably attached with a pin (not shown) or the like. The lock body 36 consists of a mounting part 37 formed to cover the upright part and a finger rest part 38 formed integrally therewith and detached from the upright part 35. A notch 33 is provided on the other side of the plate body 31 to avoid the core rod attachment portion 23 of the bottom plate 2.

In the rotary binding fitting 10 of this invention, the core rod 4 is passed through the portion 41 of the rotation plate 3 that is perpendicular to the boundary between the plate body 31 and the binding rod 32, and the core rod 4 is placed at a position corresponding to the notch 33. It is attached to a certain core rod attachment part 23. Therefore, the rotating plate 3 can be rotated about the core rod 4 as a rotation axis, and at the same time, the bottom plate 3 can be rotated by the width of the notch 33.
Can be slid on top. This time, when the moving plate 3 is moved to the leftmost end, the locking body 36 is located at the upright piece 25 of the bottom plate 2.
It is located on the left side, and the cut and raised piece 24 is located in the space of the notch 34.
comes, so the rotating plate 3 can be rotated so that the binding metal fittings are opened.

When binding a document, move the rotating plate 3 to the left end, stitch the document onto the binding rod 32, close the rotating plate 3, and then move the rotating plate 3 to the right end. It enters below the raised piece 24 and prevents the rotating plate 3 from rotating. As shown in FIG. 1, the locking body 36 is located at the bent portion 26 of the bottom plate, so when the finger rest 38 is pinched and rotated forward, the mounting portion 37 will cover the upright portion 35. At the same time as the finger rest 38 rotates as shown in FIG. The rotating plate 3 is frictionally engaged to stop the rotation of the rotating plate 3.

To open the binding tool, pinch the finger hook 38 and rotate the lock body 36 in the backward direction as shown in Fig. 1, remove the lock body 36 from the bent end portion 26, and slide the rotating plate to the left. , the left end of the notch 34 also comes off from under the cut and raised piece 24, and the rotating plate becomes rotatable.

This invention has such a structure, so it has a much simpler structure than the conventional rotating binding metal fittings, and it has created a rotating binding metal fitting that can securely lock the rotating plate with the binding rod attached. .
