[Outline of Embodiment] The clip (this clip) according to the embodiment of the present invention is such that the first clip body opens and closes with a first torsion spring, the second clip body opens and closes with a second torsion spring, the connecting part connects the first clip body and the second clip body, and adjusts the distance between the first clip body and the second clip body, and is stored in the storage parts provided in the first clip body and the second clip body, and brings the first clip body and the second clip body into contact with each other and integrates them. Thereby, the distance between the first clip body and the second clip body can be adjusted, the pages of an open book can be held, and furthermore, when they are brought closer, they can be integrated into one clip to be miniaturized.
[0018] [This Clip: Figures 1 to 9] This clip will be described with reference to FIGS. 1 to 9. FIG. 1 is a schematic view of the clip with the connecting part extended, FIG. 2 is a schematic view of the clip with the connecting part contracted, FIG. 3 is a front view of the clip with the connecting part extended, FIG. 4 is a front view of the clip with the connecting part contracted, FIG. 5 is a rear view of the clip, FIG. 6 is a right side view of the clip, FIG. 7 is a left side view of the clip, FIG. 8 is a plan view of the clip, and FIG. 9 is a bottom view of the clip.
[0019] As shown in FIGS. 1 to 9, this clip includes a first clip body 10, a second clip body 20, and a connecting part 30. Each part of this clip will be specifically described.
[0020] [First clip body 10] The first clip body 10 includes a first front part 11, a first rear part 12, and a first rotating shaft 13. In order to rotatably connect the first front part 11 and the first rear part 12 with the first rotating shaft 13, protrusions 11a, 11b are formed on the back surface of the first front part 11, and protrusions 12a, 12b are formed on the front surface of the first rear part 12.
[0021] Furthermore, the rotating shaft 13 is inserted into the holes formed in the protrusions 11a, 11b, 12a, 12b, and a first torsion spring 14 is attached to the rotating shaft 13. The first front part 11 and the first rear part 12 are opened and closed on the bottom surface side by the first torsion spring 14. A storage part 15 with a cavity for storing half of the connecting part 30 is formed on the first rear part 12.
[0022] [Second clip body 20] The second clip body 20 includes a second front part 21, a second rear part 22, and a second rotating shaft 23. And, in order to rotatably connect the second front part 21 and the second back part 22 with the second rotation axis 23, protrusions 21a, 21b are formed on the back surface of the second front part 21, and protrusions 22a, 22b are formed on the front surface of the second back part 22.
[0023] Furthermore, the rotation axis 23 is inserted into the holes formed in the protrusions 21a, 21b, 22a, 22b, the second torsion spring 24 is attached to the rotation axis 23, and the second front part 21 and the second back part 22 are opened and closed on the bottom surface side by the second torsion spring 24. A storage part 25 is formed on the second back part 22, which is provided with a cavity for storing half of the connecting part 30.
[0024] On the right side surface of the front part 11 of the first clip body 10, a convex first front convex part 16 and a concave first front concave part 17 are formed, and on the left side surface of the front part 21 of the second clip body 20, a convex second front convex part 26 and a concave second front concave part 27 are formed. Also, on the right side surface of the back part 12 of the first clip body 10, a concave first back concave part 18 is formed, and on the left side surface of the back part 22 of the second clip body 20, a convex second back convex part 28 is formed.
[0025] The concave shape is a shape that is connected and fixed in a fitted (mated) manner when the convex shape is inserted. Then, the first front convex part 16 is fitted into the second front concave part 27 and connected, the second front convex part 26 is fitted into the first front concave part 17 and connected, the second back convex part 28 is fitted into the first back concave part 18 and connected, and the first clip body 10 and the second clip body 20 are integrated.
[0026] [Connecting part 30] The connecting part 30 is formed of a square prism metal, and half of its length is stored in the storage part 15 and half of its length is stored in the storage part 25. Therefore, when the connecting part 30 is received in the receiving parts 15 and 25, the first clip body 10 and the second clip body 20 are adhered. As described above, the first front convex part 16 is inserted into the second front concave part 27, the second front convex part 26 is inserted into the first front concave part 17, and the second rear convex part 28 is inserted into the first rear concave part 18, so that the first clip body 10 and the second clip body 20 are connected and integrated.
[0027] In addition, stoppers 30a and 30b are provided at the ends of the connecting part 30 to prevent the connecting part 30 from coming out of the receiving parts 15 and 25. That is, the stoppers 30a and 30b move within the receiving parts 15 and 25. In FIGS. 2 to 9, the stoppers 30a and 30b are configured to appear on the surface side of the first back surface part 12 and the second back surface part 22, but as shown in FIG. 1, they may be configured to be hidden inside and not appear on the surface side.
[0028] Furthermore, since the shape of the cavities of the receiving parts 15 and 25 is also a quadrangular prism shape similar to the shape of the connecting part 30, the first clip body 10 and the second clip body 20 do not rotate separately about the connecting part 30, and the surfaces of the first back surface part 12 and the second back surface part 22 are kept in the same direction, which stabilizes the clamping of the pages of the book.
[0029] [Usage method of this clip: FIG. 10] The usage method of this clip will be described with reference to FIG. 10. FIG. 10 is a schematic diagram showing the usage method of this clip. As shown in FIG. 10(a), in order to keep the book in an open state, this clip pulls out the connecting part 30 from the receiving parts 15 and 25, adjusts the length of the connecting part 30 according to the size of the book, opens the first clip body 10 to clamp the upper side of one page of the book, and opens the second clip body 20 to clamp the upper side of the other page of the book.
[0030] As shown in Fig. 10(a), since the connecting part 30 of this clip is configured to straddle the upper side of the back cover of an open book, the back cover of the book will not get in the way when using this clip, which also protects the back cover. The first clip body 10 and the second clip body 20 can sandwich the book corresponding to the thickness of the left and right pages, and can stably maintain the book in an open state. Also, even when there is a difference in the thickness of the left and right pages in the open state, the first clip body 10 and the second clip body 20 can be fixed by the force of their respective springs. Since the first clip body 10 and the second clip body 20 are connected, it can prevent the book from closing and can stably maintain the open state.
[0031] Also, as shown in Fig. 10(b), to clip a book with a short width, such as a leaflet, etc., the connecting part 30 is stored in the storage parts 15 and 25 and connected, and the first clip body 10 and the second clip body 20 are integrated so that both clip bodies 10 and 20 are opened simultaneously to sandwich the book. In Fig. 10(b), since it is configured to sandwich the lower side of a memo, receipt, etc., this clip will sandwich from the upper side, and since the lower side has an expanded shape, the memo, receipt, etc. can be stably stood on this clip as a base.
[0032] In addition, when using the first clip body 10 and the second clip body 20 integrally, it is desirable to open this clip by pressing the upper right of the first front part 11 and the upper left of the second front part 21 simultaneously, and pressing the upper right of the first back part 12 and the upper left of the second back part 22 simultaneously.
[0033] However, even when either the first front part 11 or the second front part 21 is pressed, since they are connected by the connection of the first front convex part 16 and the second front concave part 27, the connection of the second front convex part 26 and the first front concave part 17, and the connection of the second back convex part 28 and the first back concave part 18, the first clip body 10 and the second clip body 20 open and close simultaneously.
[0034] [Effects of the Embodiment] According to this clip, the first clip body 10 opens and closes with the first torsion spring 14, the second clip body 20 opens and closes with the second torsion spring 24, and the connecting part 30 connects the first clip body 10 and the second clip body 20, and adjusts the distance between the first clip body 10 and the second clip body 20, and is stored in the storage parts 15 and 25, and brings the first clip body 10 and the second clip body 20 into contact and integrates them. Thereby, the distance between the first clip body 10 and the second clip body 20 is adjusted, the pages of the opened book are sandwiched and held, and furthermore, when they are brought closer, they are integrated into one clip, which has the effect of miniaturization.
[0035] In particular, according to this clip, even when there is a difference in thickness depending on the number of left and right pages when opened, the first clip body 10 and the second clip body 20 can be fixed by the force of their respective springs, and the fact that the first clip body 10 and the second clip body 20 are connected prevents the book from closing, and has the effect of stably holding the opened state.
Industrial Applicability
[0036] The present invention is suitable for a clip that adjusts the distance between two clips, keeps the book in an open state, and when brought closer, the two clips can be integrated and used.
