Abstract

PROBLEM TO BE SOLVED: To obtain a paperweight for holding an opening state of a book, in which: reading is not disturbed; pages are turned with ease; and the paperweight can be used without occupying any large space irrelevant to a large or small size of the book.SOLUTION: Weights are connected to both ends of a flexible string, and a take-up mechanism, which takes up the string by means of a spring force, is provided for at least one of the weights. A lock mechanism which fixes a take-up length of the string and a release button therefor can be provided. A spread state of a book is retained by holding, with the string, upper or lower blank space portions of pages of the open book. The weights disposed on both sides are placed adjacently to both outer sides of the open book. The page can be turned without moving the weights by shifting a central portion of the string upwardly (when the upper blank space is held), turning a paper sheet while flexibly bending the paper sheet slightly downwardly, and inserting the turned paper sheet into a space disposed under the string.

Description

  The present invention relates to a paperweight used to hold a book placed on a desk or the like in an open state.

  It is common to read a book by holding it with your hand or holding it open and turning it while turning the page. For example, when writing the contents of a book in a notebook, put your hand on the book placed on the desk. There are times when you want to keep open without attaching. If it is a thin and easy-to-open book, it will be kept as it is if it is opened and placed on the desk, but a thick book or a book that is bound tightly will be closed if it is opened and placed on the desk, The paper is greatly swollen and the desired page cannot be read. In such a case, a paperweight is placed so as to be passed to the opened left and right pages so that a desired page is held open.

  However, paperweights are generally made of metal, and even transparent glass is thick, so the places where paperweights are placed cannot be read. Therefore, it is necessary to make a paperweight while reading. Especially when browsing, the paperweight must be moved frequently, and when turning the page, it is necessary to remove the paperweight, turn the page, and set the paperweight again. It is very troublesome when writing.

  As means for solving this trouble, Patent Documents 1 and 2 propose a paperweight having a structure in which weights are attached to both ends in the longitudinal direction of an elongated transparent plate. This paperweight is used with a transparent plate so that it spans both the left and right pages of an open book. The weights at both ends are located on both sides of the open book, and the open page is only covered with a thin transparent board, so the area covered with the paperweight is small, and the letters on the covered area can be read through the transparent board. The book can be read as it is until the page is turned.

  However, even if a transparent plate holds the open page, the light is bent or reflected at the upper and lower edges of the plate, so that it cannot be read accurately. In particular, in horizontal writing, one line cannot be read, so the weight needs to be shifted.

  If a hard transparent plate that is difficult to bend is used as the transparent plate, the paperweight becomes large and inconvenient to carry. However, there is a problem that the weight must be opened and pressed all the way to the left and it takes up space, and in any case, it is inconvenient in practice unless you prepare a large or small item that matches the size of the book .

  The problem is that turning pages is troublesome. If you hold the left and right weights with your left and right hands, when you remove the paperweight from the book, the book will close or the page will move, so you must move the paperweight with one hand. In the structure in which the paperweight is lifted by holding the middle of the transparent plate with one hand, the transparent plate becomes considerably thicker, and the upper and lower edges of the plate become unreadable. On the other hand, when a flexible transparent plate is used, one hand lifts the weight with one hand and the other hand turns the page. When turning the page, it is necessary to lift one weight high or If you try to put it in a shifted position, the direction of the other weight will change or the transparent plate will be twisted, so you will have to correct the position of the paperweight after turning the page.

  The present invention is intended to provide a paperweight for reading books with a structure that eliminates such problems, and does not obstruct the reading of an open page, can be easily turned, and the size of a book can be reduced. Regardless of the location, the issue is to obtain a paperweight that can maintain the spread state.

  The writing paperweight of the present invention has a weight 2 and 3 connected to both ends of a flexible string 1, and a winding mechanism 4 for winding the string 1 by spring force is provided on at least one of the weights 2. It is. The one weight 2 can be provided with a lock mechanism 5 for fixing the winding length of the string 1 and its release button 6 as necessary. The winding mechanism 4 has a simple structure in which a pulley 41 that is urged to rotate in the winding direction of the string 1 by a winding spring (spring spring) 42 is provided.

  A paperweight for book-reading according to the present invention holds the open state of a book by pressing the upper or lower margin of the opened page with the string 1. The weights 2 and 3 on both sides are placed adjacent to both outsides of the open book 11, but the edges on the side in contact with the book may be placed so as to hold the left and right margins of the page. When turning the page, using the string 1 and the flexibility of the paper of the book, the middle part of the string 1 is moved upward with one hand (the same applies hereinafter when the upper margin of the page is pressed with the string 1). It is possible to turn the page easily without moving the weights 2 and 3 by turning the paper to be turned and bending it so that it is slightly shifted downward, and moving the turned paper so as to be inserted under the string 1. it can.

  Examples of the preferable string 1 include a thin and flat so-called flat string that may be attached as a bookmark to a hardcover book, and a round or square cross section made of a material such as a toothbrush. The former has excellent flexibility, and the latter has excellent durability.

  The paperweight of the present invention holds the open state of the book by holding the upper or lower margin part of the open book with the string 1, so there is no possibility of hindering reading. The spread state of the book is maintained by the tension of the string 1, but the weights 2 and 3 on both sides are placed close to the left and right outside of the book with the winding mechanism provided on the weight 2 regardless of the size of the book. Therefore, regardless of the size of the book, the necessary tension can be applied to the string 1 and the place is not taken up. Then, since the page of the book can be turned without moving the weights 2 and 3 using the flexibility of the string 1 and the flexibility of the paper of the book, the page turning operation is facilitated. Further, when not in use, the string can be wound up in one weight 2, which is convenient for carrying and storage.

  Embodiments of the present invention will be described below with reference to the drawings. The paperweight for book reading of this invention is provided with the flexible string 1, and the weights 2 and 3 provided in the both ends. The weights 2 and 3 in the figure have a structure in which resin covers 22 and 32 are mounted on thick plate-like metal bases 21 and 31 having a weight that does not move due to a reaction force from a pressed book. .

  In one weight 2, a winding mechanism 4 for the string 1 is accommodated in a space between the cover 22 and the metal base 21. The other weight 3 is not provided in the space between the cover 32 and the metal base 31, and a hook 33 is provided at one end thereof, and the tip of the string 1 is tied to the hook 33.

  In the illustrated embodiment, the weight 3 on the distal end side of the string 1 has the same shape as the weight 2 on the proximal end side, but it can be made only of a metal substrate, or it can be of a truncated pyramid shape used for fishing. Any shape can be used as long as it does not roll and move.

  As shown in FIG. 2, the winding mechanism 4 in the weight 2 includes a pulley 41 that is urged to rotate in the winding direction of the string 1 by a winding spring 42. The pulley 41 is pivotally supported on a shaft 43 standing on the metal base 21 so as to be freely rotatable. A winding spring 42 is provided between the tip of the shaft and the pulley 41 and wound around a winding groove of the pulley 41. The base end of the string 1 is fixed to one place of the winding groove. The cover 22 is provided with a draw-out port 23 for the string 1, and the other weight 3 is connected to the tip of the string 1 drawn from the draw-out port.

  A lock mechanism 5 for fixing the drawing position (drawing length) of the string 1 is provided in the vicinity of the drawing port 23. The lock mechanism 5 shown in the figure is a cam that is rotatably provided around a shaft 53 provided on the cover, and a protruding portion 54 of the cam 51 by a spring force of a winding spring 52 that urges the cam to rotate, and a cover. The string 1 is clamped between the receiving part 24 and the receiving part 24 integral with 22 and fixed. The cam 51 is integrally provided with a release button 6 for pushing the cam 51 in the direction opposite to the biasing direction of the winding spring 52, and this release button 6 protrudes to the outside of the side surface of the cover 22. .

  When the user pushes the release button 6 with the finger of the hand holding the weight 2, the string 1 is unfixed by the lock mechanism, and when the finger is released from the release button 6, the string 1 is pulled out by the spring force of the winding spring 52. It is drawn from the port 23 and wound around the pulley 41.

  FIG. 3 is a diagram showing a use state of a paperweight for a book reading having the above structure. As shown in the figure, the paperweight for book reading according to the present invention has margins above or below the book 11 opened by the string 1 that puts the weights 2 and 3 in the immediate vicinity of the left and right of the book 11 and connects the two. Use with the part held down. That is, the string 1 is pulled out longer than the width of the opened book and placed on the book, and both sides of the blank portion above (or below) the book in which the hook 33 of the weight 3 and the drawer opening 23 of the weight 2 are opened. When the release button 6 is pressed in the position, the extra length of the string 1 is wound up and pulled between the weights 2 and 3, and the upper side (or the lower side) of the opened book is pressed to hold the book. The spread state is maintained.

  When turning the page, push the middle part of the string upward with the fingertip of one hand, pull the outer side of the paper to be turned down slightly with the other hand, turn it off the string 1, and then turn the upper side of the turned paper. Is inserted under the string 1, the page can be turned without moving the weights 2 and 3.

  When not in use, the string 1 is caught in the weight 2 by bringing the weights 2 and 3 closer together while the release button 6 is pressed, so it is easy to carry and takes up space even if it is always placed on the desk. Alternatively, it can be used as a normal paperweight as it is.
