Description

[Detailed description of the invention] This invention relates to a bookmark string that can be inserted into a desired page of a book that is being read.

Conventionally, bookmark strings are attached by gluing the base end to the inner surface of the upper edge of the spine of a book, but this gluing requires manual labor, which increases bookbinding costs. An increasing number of books are not equipped with bookmark strings, and the inconvenience has been pointed out.

On the other hand, the bookmark string of this invention is made separately from the book so that it can be easily attached to various books as needed. One end of the string 1 is folded back a little length and tied together to form a ring-shaped trap 2.
It is made of rubber bands 3, 3, and in this case,
The size of the trap 2 is such that the inner diameter allows the two rubber bands 3, 3 to move sufficiently.

This invention has the above-mentioned structure, and in order to use it, as shown in Figure 2, the base end of the flat string 1, the trap 2, is attached to the upper edge of the spine of the desired book, and Stretch the rubber bands 3 and 3 and hook them on the front and back covers respectively, move them to each binding part that is the border with the spine, and after fixing and securing these parts by sandwiching them from the front and back, attach the flat string 1. It is used by inserting it into the required page of the book,
In this case, when installing the trap 2, the rubber bands 3, 3
Since the rubber bands 3 and 3 hooked to the front and back covers are formed in a size that allows for sufficient movement, the rubber bands 3, 3 attached to the front and back covers naturally equalize the tension on the left and right parts that sandwich these covers. It slides into the trap 2, thus eliminating curvature of the front and back covers and damage caused by biting of the rubber band.
The fact that the trap 2 is of a considerable size means that when attached, the trap 2 is stretched in the horizontal direction according to the width of the spine to prevent the rubber bands 3 from being bitten into the spine. ing.

Incidentally, as shown in Fig. 2, books are usually wrapped with an outer cover 4, so the rubber bands 3.3 are covered with this outer cover and are not exposed to the outside, giving a good appearance. .

As described above, this invention has many advantages, such as being able to be easily attached to a desired book and using it at any time, and being extremely simple in structure and inexpensive.
