Description

Detailed Description of the Invention

Industrial application fields

  The present invention relates to a thin binding tool for binding a thin piece such as a piece of paper, and more specifically, a member for binding a thin piece (ring-shaped one) has a function of making a punch hole, thereby eliminating the need for a punch called a punch. About.

  Generally, when collecting or storing various materials, it is convenient to make a hole in the material with a punch called a punch and bind this hole through a binder binding member (ring-shaped one). In addition to the binder that binds the material, a punch is required to make a hole in the material. This punch is quite heavy and bulky and hard to carry. Therefore, it was inconvenient to collect data at various places and walk around.

Problems to be solved by the invention

  The object of the present invention is to eliminate the need for a heavy and bulky punch called a punch by providing a binding member (ring-shaped member) of a thin binding tool called a binder with a function of making a punch hole. However, it is in a place that makes collecting materials convenient.

Means to solve the problem

  In order to achieve the above object, according to the first aspect of the present invention, in the first aspect of the present invention, the binding member includes a binding member rotatably provided on the support base, and a blade body having a cutting blade around the hole. A hole formed in a thin piece inserted into a hole in the body and placed on the blade body, and the hole thus formed in the thin piece is passed through a binding member, and in the second invention, the binding provided rotatably on the support base A hole provided with a member and a hole and having a cutting blade provided at the front end portion of the binding member is inserted into the hole to make a hole in the thin piece placed on the hole, and thus the hole formed in the thin piece Is configured to pass through the binding member.

  FIG. 1 shows an embodiment of a thin binding tool according to the present invention. First, in FIG. 1 (a) (see also FIG. 1 (b) in which the cross section taken along the line AA 'is enlarged), a rotating shaft 7 is attached to the support base 1. A binding member 9 provided in the center so as to be freely rotatable (in the drawing, a rotation shaft 8 thinner than the rotation shaft 7 is fitted in the bearing portion and rotates around the shaft), and is cut around the hole 3. A blade body 2 having a blade 4 is provided. The binding member 9 has a ring shape, and the portion H on the tip side has an arc shape (or a substantially arc shape) centered on the rotation center of the binding member 9. 3 is configured so that it does not hit even if it is fitted. The front end portion of the binding portion 9 has a slightly smaller cross section than the hole 3 because it is necessary to open the hole with the cutting blade 4 by inserting a thin piece into the hole 3, and from here, the cross section of the binding member 9 is It becomes gradually smaller by the joint portion 10 and becomes almost constant thereafter (this makes it easier for the bound thin piece to move) and slightly thicker at the root portion. The blade body 2 has a structure having a cutting blade 4 (the cutting blade 4 is located at a position protruding from the support base 1) around the hole 3, and the cutting blade 4 has a crest portion 5 and a trough portion 6 as shown in FIG. And can easily bite into the thin piece placed on the blade body 2 (of course, the blade body as shown in FIG. It is necessary to sharpen the cutting edge 4). In this case, the cutting edge 4 may be sharpened to sharpen the sharpness, but for safety, it is preferable to have a small roundness at the top of the peak portion 5 so that it will not be injured even if a finger hits it. (This will make the sharpness dull, but since the finger does not enter the valley portion 6, sharpness can be restored by sharpening this portion). An operation member 12 is built in the support base 1, and a projection 11 formed on the rotating shaft 7 is configured to fit into a notch 13 (see FIG. 1D) formed on the operation member 12. That is, when the operation member 12 is fully pulled out as shown in the drawing, the projection 11 is completely pulled out from the notch 13 as shown in FIG. 1 (d) (the operation member 12 is viewed from above), and the binding member 9 is When the operation member 12 is pushed in, the protrusion 11 is pushed into the back of the cutout portion 13 (S portion), and in this state, the binding member 9 is fixed, and the tip portion thereof is in the hole 3. It is in the inserted state. Next, how to use is explained. When the operation member 12 is fully pulled out as shown in FIG. 1 (a), the projection 11 comes out of the notch 13 as shown in FIG. 1 (d), and the binding member 9 becomes rotatable. Therefore, in FIG. 1 (b), a thin piece such as a piece of paper is placed on the blade body 2, is pushed in until it hits the claw 16, is positioned, and the binding member 9 is pushed down from above (there are two binding members 9 in the figure). , Each of them is pushed down simultaneously), and a hole is made in the thin piece by the cutting blade 4. Normally, the projection 11 is pushed down until it hits the stopper portion 1 ′ of the support base 1, but when the operating member 12 is completely pushed in this state, the projection 11 is pushed toward the back of the notch portion 13, and the binding member 9 is It can no longer rotate and is fixed (at this time, the tip of the binding member 9 is in the hole 3). Next, as shown in FIG. 3 (d), if the thin piece 18 pierced by the cutting blade 4 is lifted upward, it will come out of the blade body 2, and then the presser length l under the claw 16 is short, so that the claw 16 The flakes can be moved freely through the binding ring 9 (the flakes once pulled out from the claws 16 do not go under the claws 16 again). Thus, if the thin piece is pushed down the binding member 9 to make a hole, it immediately passes the thin piece through the binding member 9 and can be bound. If a piece of paper, such as a document, is stapled with staples, it is better to make a hole in two or three times as shown in FIG. 3 (e). The other half is put on the blade body 2 as it is without removing it from the blade, and a hole is made. Here, in FIG. 1C, the diameter of the hole opened in the thin piece by the blade body 2 is d, and since this d is larger than the diameter of the front end portion of the binding member 9 (about 1 mm larger). When the bound thin piece is extracted from the binding member 9 or inserted in the reverse direction, it is performed smoothly (in the case of FIG. 3C, the cutting blade 4 is sharp, so a hole having a diameter d 'is opened). If the thin pieces are bound and the binding member 9 is inserted into the hole 3 of the blade body 2 and fixed, the height of the blade body 2 is as low as about 3 mm as shown in FIG. Since the distance δ between the member 9 is as small as about 0.5 mm, the tip of the finger only hits the binding member 9 as shown, and does not hit the cutting blade 4 of the blade body 2. The thin binding tool according to the present invention is attached to a cover as shown in FIG. 3 (a) and binds many thin pieces such as paper pieces. In FIG. 1A, the rotating shaft 8 that is thinner than the rotating shaft 7 is supported by the bearing portion. However, the rotating shaft 7 is attached to the bearing portion 17 formed on the support base 1 as shown in FIG. The rotating shaft 7 may be fitted and supported by the bearing portion 17. In FIG. 11 (a), there are two binding members 9. However, as shown in FIG. 3 (g), four binding members 9 may be provided. In this case, it is difficult to press all four of the binding members 9 simultaneously. Therefore, since only two pieces are inevitably pushed, the other two pieces are likely to be cut easily if a plurality of thin pieces are overlapped and forcibly punctured (especially when the binding ring 9 is made of plastic). In order to prevent this, it is conceivable to divide the rotary shaft 7 in the middle as shown in FIG. 3 (h), and to make this portion a meshing portion 20, which is pushed by a spring 19 and meshed with each other. Therefore, for example, when two binding members 9 on the front side are pushed down, if the forcible force is applied to the two opposite sides, the engagement of the concavity and convexity of the meshing portion 20 is released against the spring 19 to prevent cutting. I can do it. Further, as shown in FIG. 3 (R), the binding member 9 is connected to the bearing portion 21 that fits into the rotation shaft 7, and when the two on the near side of the binding member 9 are pushed down, the two on the opposite side are pressed. If an unreasonable force is applied, the projection 22 formed on the rotating shaft 7 comes out of a recess (formed on the bearing portion 21) into which the projection 22 is fitted, and the bearing portion 21 is idled to prevent breakage. Next, when the cutting blade 4 is sharp in FIGS. 1A and 1B, it is desirable to provide a safety guard 23 so as to cover the cutting blade 4 as shown in FIG. This is a through portion for passing the binding member 9). However, since the safety guard 23 is a fixed type, once a hole is made in a thin piece, it must be extracted and then re-passed through the binding member 9, which is troublesome. Therefore, the safety guard may have a movable structure as shown in FIG. That is, as shown in FIG. 2 (b) (see also FIG. 2 (c) viewed from the direction B), the safety guard 25 is usually provided so as to surround the blade body 2, but it is safe. Only when opening, the safety guard 25, which is rotatable about the rotation shaft 26, is tilted as shown in FIG. 2 (d) to expose the blade body 2, and a hole is made. In this case, the safety guard 25 may be rotated around the rotation shaft 26 ′ instead of the rotation shaft 26. Furthermore, as shown in FIG. 2E, if the tip of the cutting edge 4 is provided in the recess so as to be buried slightly (about 0.5 mm) from the surface of the support base 1, the diameter of the recess is small, so that a finger does not enter and is safe. Yes (the jagged height of the cutting edge 4 is also reduced).

  In FIG. 1, the cutting blade 4 is provided on the support base 1 side, but FIG. 4 shows a structure corresponding to the structure provided on the binding member 9 side. That is, in FIG. 4 (a) (see also FIG. 4 (b) showing the CC ′ cross section), a cutting blade 28 is provided at the tip of the binding member 27, and a hole 32 is provided in the support base 1. ing. FIG. 4 (c) is an enlarged view taken along arrow D in FIG. 4 (b), and shows a specific cross section of the cutting blade 28 when the cutting blade 28 is in the vicinity of the hole 32 (for example, FIG. The cross section in the x direction, the y direction, and the z direction is conceivable as in (), but the one end portion 28a of the cutting blade 28 in the cross section of the connecting portion 30 between the blade body 29 and the binding member 27 is considered. It protrudes outward from the end portion, and a certain height difference is provided between the one end portion 28a and the other end portion 28b of the cutting blade 28. In this way, the hole opened in the thin piece by the cutting blade 28 is an oval long in the y direction, and is longer than the length of the connecting portion 30 by an amount corresponding to λ. Since it can pass through the front end of the binding member 27 with a gap (λ = 1 mm or so), it can be easily passed when the bound thin piece is removed from the binding member 27 or inserted in reverse (of course, the hole 32 is also in the y direction). Long oval). In this case, if a cross section in the x direction is considered and a clearance corresponding to the clearance λ is given also in this cross section, the front end portion of the binding member 27 can be passed with a slight clearance in both the x direction and the y direction. (The holes that can be drilled in the flakes can be round). However, the above is not indispensable, and the configuration shown in FIG. 4 (e) in which the front end portion of the binding member 27 is not formed as shown in FIG. 4 (c) may be used (the bound thin piece is extracted from the binding member 27). Or a little bit of trouble when inserting or inserting) Reference numeral 31 denotes a connecting portion that gradually becomes thinner from the connecting portion 30 and is connected to the binding member 27, and is used for smoothly passing a hole formed in the thin piece. Although the cutting blade 28 may be sharp, it is desirable to have a small roundness at the corner for safety. In FIG. 4C, the cutting blade 28 may have a jagged structure having a crest 33 and a trough 44 as shown in FIG. In this case as well, for safety, it is preferable to give a small roundness to the top of the peak (since no finger enters the valley 34, this part may be sharpened to improve sharpness). The binding member 27 and the rotation shaft 7 may be made of plastic or metal. In the latter case, the strength is high, and when aluminum or an alloy thereof is used, a die-casting method can be performed. (The same applies to the case of FIG. 1). 4 is the same as that of FIG. 1 in that the thin piece is placed on the hole 32, and the blade body 29 having the cutting blade 28 provided at the tip of the binding member 27 is placed in the hole 32. Insert a hole into the hole. Reference numeral 16 denotes a claw as described in FIG.

  5 (a) includes a binding member 35 and a hole 37 that are rotatably provided on the support base 1, and the binding member 35 is pushed down twice so that the tip of the binding member 35 becomes a hole 37. Inserted twice, a hole is made in the thin piece placed on the hole 37, and the hole is formed in such a manner that the cross section of the hole is larger than the cross section of the cutting blade 36 provided at the tip of the binding member 35. It is easy to pass the tip of 35. Although the binding member 35 viewed from the direction of the arrow E is enlarged and shown in FIG. 5B, the cutting blade 36 may have a crest and a trough as shown in FIG. When a thin piece such as a piece of paper is placed on the hole 37 and pushed into contact with the nail 16 to be positioned, and the binding member 35 is pushed down for the first time, a round hole as shown in FIG. open. Next, as the second time, the binding member 35 is pushed to the opposite side against the spring 38 (pushing about 0.5 to 1 mm), and if pushed down as it is, for example, an oblong hole as shown in FIG. 37 is of course oval to match this). In FIG. 5 (f), the rotation shaft 37 is pushed to the other side by the cam surface 39 and the spring 40 only by pushing down the binding member 35 once, for example, an oval hole as shown in FIG. The hole is made easy to pass through the tip of the binding member 35. FIG. 5G shows an enlarged view of the front end portion of the binding member 35 as viewed from the direction of the arrow F. In the case of FIG. 5 (f), the spring 40 is not necessary if the cam surfaces 39 are provided facing each other as shown in FIG. 5 (h).

The invention's effect

  According to the present invention, since the binding member is provided with a function of making a hole, a puncher called a heavy and bulky punch is not required, the load is reduced, and it becomes very convenient. Therefore, when collecting and gathering materials in various places, you can feel the convenience, and you cannot forget or lose the punch and you can't bind the materials. In the present invention shown in FIGS. 1 and 4, punching a thin piece immediately leads to binding through the binding ring 9 (27), so that it can be quickly performed. According to the present invention, a hole can be easily formed and bound, so that it can be conveniently used as a thin binding tool for a scrapbook.
