Description

[Detailed explanation of the idea] "Industrial application field" The present invention relates to a bookmark with a clip.

``Prior art'' In the past, bookmarks were generally strips of paper with thin strings attached to them, but since they were simply inserted between books, they could be used to carry books around or The book often slipped off the moment I opened it and was lost. For this reason, a bookmark with a clip as shown in FIG. 15 was later devised. The bookmark with a clip is formed by bending an elastic plate such as plastic into a U-shape to form a clip part A that clips the cover of the book,
A string C, which is inserted between books, is attached to the bent base A' of the clip part A via a link B.

This bookmark with a clip was able to overcome the drawbacks of conventional bookmarks in that it does not slip when carrying or opening the book, but since the length of the string C is constant, it is difficult to use this bookmark. The drawback was that the types of books that could be used were limited. In other words, there are various types of books, from tall ones to short ones. However, conventional bookmark strings with clips are made to be somewhat long so that they can cover as many types as possible. For this reason, when used on short books, the tip of the string protrudes too much from the bottom of the book, which is unsightly, and on the other hand, when used on tall books, the string is not long enough and is difficult to use. There is a problem.

``Problems to be solved by the invention'' This invention was created in view of the above points, and the length of the string attached to the clip part can be adjusted appropriately according to the book. It is an object of the present invention to provide a bookmark with a clip which can solve the above-mentioned problems and also allows the string to be rolled into a string storage box when not in use.

"Means for Solving the Problems" The present invention will now be described in more detail with reference to illustrated embodiments.

Fig. 1 is a perspective view of the first embodiment of the present invention;
The figure is a central vertical sectional view of the string storage box, Figure 3 is an enlarged cross-sectional view taken along the line in Figure 2, Figure 4 is an enlarged cross-sectional view taken along the line in Figure 2, and Figure 5 is an enlarged line taken in Figure 2. FIG.

In the figure, reference numeral 1 denotes a clip portion made of plastic or the like, which is designed to hold the cover of a book between opposing gripping pieces 1a and 1a'. 2 is the clip portion 1
This is a string storage device installed at the top of the lanyard. The string storage device 2 has a cylindrical string-wrapping shaft 4 in the center of a rectangular string storage box 3 with a string outlet 3a provided at a predetermined position.
At the same time, a disk 5 having a square hole 5a (described later) for adjusting the band plate in the center is fixed to one end surface of the string-wrapping shaft 4, and a string storage box 3 is attached on the other side.
A string storage box 3 for the operating rod 7 is attached to the side wall of the operating rod 7 so as to pass through the side wall of the operating rod 7, and is fitted into a hole 3b provided in the side wall so as to be slidable in the horizontal direction, and is returned to its original position with a coil spring 6. A strip plate 8 twisted into a screw shape that fits into the square hole 5 of the disk 5 is provided on the inner end surface.
A ratchet mechanism 10 is provided on the string winding shaft 4 to which the string 9 is fixed and further connected to and wound around the base of the string 9.

The ratchet mechanism 10 also includes a ratchet 11 fixed to the string winding shaft 4, and a click 13 pivotally supported on the inner wall of the string storage box 3 via a pivot 12.
It is attached to the side wall on the back side of the string storage box 3 so as to pass through it, and is slidably fitted into a hole 3c provided in the side wall and returned to its original position with a coil spring 14. It consists of an operating rod 15.

Next, the operation of the above embodiment will be explained.

First, the clip portion 1 is clamped to the cover of a book (not shown). In this state, the operating rod 7 is moved by the coil spring 6.
Press against the action of the string storage box 3 inward (toward the right in the figure). As the operating rod 7 moves into the string storage box 3, the band plate 8 fixed to the end face of the operating rod 7 also moves at the same time, and the disc 5 rotates through the band plate 8 and the square hole 5a of the disc 5. and the disk 5
As the string is rotated, the string winding shaft 4, which is fixed to the end face thereof, also rotates and the string 9 is let out.

Then, tie the string 9 to the appropriate length according to the height of the book.
When the operating rod 7 is stopped when the string 9 is let out, the click 13 comes into contact with the teeth of the ratchet 11 to prevent reverse rotation, and the string 9 is maintained in the state of being let out to a predetermined length.

Further, when the length of the string that has been let out is shortened or the string is to be stored in the string storage box 3, it is only necessary to press the operating rod 15, and the click 13 is disengaged from the teeth of the ratchet 11 and the string is removed. The winding shaft 4 rotates in the opposite direction and begins to wind the string 9. If the pressure on the operating rod 15 is released at an appropriate timing, the length of the string 9 can be shortened or the string 9 can be completely wound into the string storage box 3. It is something that can be put away.

Next, a second embodiment of the present invention shown in FIG. 6 will be described.

FIG. 6 is a central vertical sectional view of the string storage device.

The difference between this embodiment and the first embodiment is that a cylindrical body 17 with a spiral groove 16 cut in the circumferential surface is used in place of the disk 5 in the first embodiment, and a strip plate 8 is used. Instead, a push rod 19 is used, which has a pin 18 attached to its tip end that fits slidably into the groove 16.

Therefore, since the other configurations are the same as those of the first embodiment, the same members are given the same reference numerals and detailed explanations will be omitted.

However, according to this embodiment, when the operating rod 7 is pushed into the string storage box 3 against the action of the coil spring 6, the push rod 19 moves rightward in the figure, and the pin 18 attached to the tip thereof moves. is the groove 16 of the cylindrical body 17
The cylindrical body 17 is rotated by pressing while sliding on the inside. Furthermore, through the rotation of the cylindrical body 17, the string-wrapped shaft 4 is rotated.

Next, the third aspect of the present invention shown in FIGS. 7 and 8 will be described.
An example will be described.

FIG. 7 is a longitudinal cross-sectional view, and FIG. 8 is a cross-sectional view taken along the line in FIG.

The differences between this embodiment and the first embodiment are as follows:
A bevel gear and a rack and pinion are used in place of the disc 5 and strip 8 in the first embodiment.

Specifically, a bevel gear 20 is fixed to the end face of the string-wrapping shaft 4, and the bevel gear is attached to a rotating shaft 21 installed in the string storage box 3 so as to be perpendicular to the string-wrapping shaft 4. This embodiment is different from the first embodiment in that the bevel gear 22 that meshes with the pinion 20 and the pinion 23 are fixed together, and the rack 24 that meshes with the pinion 23 is connected to the end surface of the operating rod 7 inside the string storage box 3. It is.

However, in this embodiment, when the operating rod 7 is pushed into the string storage box 3, the rack 24 moves to the right in the figure, and the pinion 2 meshed with the rack 24 moves to the right in the figure.
Rotate 3. Along with this, the rotating shaft 21 rotates, and the string-wrapped shaft 4 rotates via the two bevel gears 22 and 20.

Incidentally, since the other configurations and functions are the same as those of the first embodiment, the same members are given the same reference numerals and detailed explanations will be omitted.

Next, a fourth embodiment of the present invention shown in FIGS. 9 to 12 will be described.

9 is a perspective view, FIG. 10 is a central vertical cross-sectional view of the string storage device, FIG. 11 is an enlarged cross-sectional view taken along the line - in FIG. 10, and FIG. 12 is an enlarged cross-sectional view taken along the line - in FIG. 10.

The differences between this embodiment and the first embodiment are as follows:
The string-wrapped shaft 4, the disc 5, in the first embodiment,
Instead of the strip plate 8 and the coil spring 6, an operating shaft, a reel with a cord, and a spiral spring are used. In the illustrated embodiment, the shape of the string storage box 3 is cylindrical in longitudinal section.

Note that the other configurations are almost the same as those of the first embodiment.

However, to explain this example more specifically,
The cylindrical operating shaft 25 is attached to the side wall of the string storage box 3 so as to pass through it, and is fitted into the hole 3d provided in the side wall so as to be slidable in the horizontal direction.The inner end of the string storage box 3 is hollowed out. A fitting hole 25a for a support shaft, which will be described later, is bored in the support shaft fitting hole 25a, and a support shaft 26 protruding from the inner surface of the side wall of the string storage box 3 opposite to the side wall having the hole 3d can be freely slid into the support shaft fitting hole 25a. Furthermore, a plate-shaped stopper 27 is provided protrudingly from the end of the operating shaft 25 on the support shaft 26 side, and the operating shaft 25 is
A coil spring 28 is inserted between the end face on the support shaft 26 side and the side wall on the support shaft 26 side, so that the plate-shaped stopper 27 is always fitted into a notch in the vertical wall of the string winding reel described later. On the other hand, a notch 31 into which one end of the plate-shaped stopper 27 fits is provided in the vertical wall 30a of the string-wrapped reel 30, which is rotatably attached to the operating shaft 25 with a support cylinder 29 at a substantially central portion thereof. At the same time, a spiral spring accommodating annular part 32 is integrally provided on the string winding reel 30, a spiral spring 33 is accommodated in the spiral spring accommodating annular part 32, and one end of the spiral spring 33 is housed in the spiral spring accommodating annular part 32. It is connected to the inner surface of the spiral spring accommodating annular portion 32, and the other end is connected to the operating shaft 25.

Reference numerals 34 and 34 denote guide plates, which are provided on the inner surface of the side wall of the string storage box 3 on the side of the support shaft 26. The guide plates 34, 34 are provided to move the operating shaft 25 only in the horizontal direction without rotating it.

Next, the operation of this embodiment having the above configuration will be explained.

When pulling out the string 9, pinch the end of the string 9 and pull it out. When pulling out the string 9, first pull out the operating shaft 2.
5 against the coil spring 28 and push it inside the string storage box 3. As a result, the operating shaft 25
The plate-shaped stopper 27 has a notch 31 provided in the vertical wall 30a of the string winding reel 30 as shown by the arrow.
It's more out of place. In this state, when the end of the string 9 is pinched and pulled, the string winding reel 30 rotates about the operating shaft 25 as the string is pulled out.
When the reel 30 with the string winding rotates in this manner, the spiral spring 33 is also gradually charged with energy. When the pressure on the operating shaft 25 is released after it has been pulled out to the required length, the operating shaft 25 returns to its original position by the action of the coil spring 28, and the plate-shaped stopper 27 again engages the notch of the string-wound reel 30. 31 to prevent the reel 30 from rotating in the opposite direction. As a result, the string is pulled out to the required length and held.

Further, when shortening or storing the string, this is done at the timing when the pressure on the operating shaft 25 is released. That is, when the operation shaft 25 is pressed again, the plate-shaped stopper 27 comes off from the notch 31 of the string-wrapped reel 30, and the string-wrapped reel 30
is rotated in the direction of winding the string by the action of the spiral spring 32. At this time, if you momentarily release your finger from the operating shaft 25 to release the pressure, the string 9 will be moved to the string winding reel 3.
The string 9 will be wound up only slightly at zero, but if you hold it down for a long time, the string 9 will be completely wound up on the string winding reel 30.

Finally, a fifth embodiment of the present invention shown in FIGS. 13 and 14 will be described.

FIG. 13 is a central vertical sectional view, and FIG. 14 is an exploded perspective view of the main parts.

This embodiment is a simpler version of the fourth embodiment, and is attached to the side wall of the string storage box 3 so as to pass through it, and is fitted into a hole 3d provided in the side wall so as to be slidable in the horizontal direction. A cylindrical operation shaft 35
A coil spring 36 is inserted between the inner end surface of the string storage box 3 and the side wall facing the hole 3d of the string storage box 3, so that the spring plate is always in a position where it bites into the teeth of the ratchet described later. At the same time, the other end of the spiral spring 37, whose one end is connected to the inner wall of the string storage box 3, is connected to the operation shaft 35, and the ratchet 38 is fixed, and the ratchet 38 is further bitten into the teeth of the ratchet 38 to prevent rotation. A blocking plate spring 39 is attached to the inner wall of the string storage box. Furthermore, in this embodiment, the string 9 is wound around the operating shaft 35 itself.

However, in this embodiment, when pulling out the string 9, the end of the string 9 is pinched and pulled out, and when the string is pulled out, the operating shaft 35 rotates, and the spiral spring 37 is loaded with energy. It is something that will be done.
When the string is pulled out to the required length, the spring plate 39 bites into the teeth of the ratchet 38 and is held at the pulled out length. Further, when shortening or storing the string, it is sufficient to press the operating shaft 35, and as a result, the spring plate 39 is disengaged from the teeth of the ratchet 38, and the operating shaft 35 is placed under the action of the spiral spring 37. Therefore, it rotates in the winding direction.

``Effects of the Invention'' The present invention has the above-mentioned structure and operation, and allows the length of the string attached to the clip to be adjusted as appropriate to match the length of the book. Therefore, it is possible to completely eliminate the problems of conventional bookmarks, such as the bookmarks protruding greatly from the book or being too short to be difficult to use. Also,
When not in use, it can be rolled up in a string storage box, making it practical and highly effective.
