Description

  The present invention relates to a seesaw-type book stand, and more specifically, to a seesaw-type book stand that is less likely to slip or lose its shape such as books and magazines.

  Soft-covered books and magazines with weak backs were difficult to stand up against the bookshelf, curved and slipped off, and could not be stored in an organized manner. Up to now, book stands have been proposed for organizing such books and magazines that do not lose their shape. For example, a proposal for a main stand comprising an elongated bottom plate having a flat portion and a partition portion standing upright from the flat portion of the bottom plate, and having one or more convex protrusions on the partition portion opposite to the partition portion (Patent Document 1). By pressing a cover of a book or the like against such a partition, even a soft cover book or the like can be stored while suppressing deformation.

  However, in the state in which a plurality of partitioning portions that stand upright on the flat portion of the plate portion are provided, for example, a book or the like is displayed on the left side of the book stand so as to press the cover against the partitioning portion, specifically, the book When the bookcase is tilted so that the left edge of the booklet is in contact with the floor when the left cover of the book is pressed against the partition, the weight of a relatively heavy book is displayed on the right side of the bookcase. As a result, the bookshelf tilts so that the bottom right edge of the plate stand comes into contact with the floor, and as a result, the books displayed on the left side of the bookshelf are shifted to the right due to a change in the tilt of the bookstand. was there.

  The seesaw type book stand of the present invention includes a seesaw substrate in which a plurality of coaxially arranged connecting holes are formed to penetrate in the thickness direction, side plates that are fixed upright on both the left and right sides of the seesaw substrate, and a seesaw The back plate on which the substrate and the side plate are locked, the bottom plate in which a plurality of support portions for supporting the seesaw plate are formed at positions corresponding to the connecting holes, and either the left or right ends of the bottom plate between the seesaw substrate and the bottom plate It is characterized by comprising a gap plate fixed to one side, and the support portions are respectively inserted into the corresponding connecting holes and rotatably support the seesaw substrate.

  According to the above configuration, since the gap plate exists between the seesaw substrate and the bottom plate, the seesaw substrate is moved to the other side even if the books are additionally displayed in a state where the seesaw substrate is inclined to one side by the display of books or the like. The seesaw substrate can be kept parallel to the bottom plate without tilting. Thereby, it can prevent that a book etc. slip down.

  Also, the seesaw-type book stand of the present invention has one magnet fixed on the gap plate and the other magnet fixed on the seesaw substrate among the pair of magnets facing different poles, and the same poles facing each other. Of the pair of magnets, one magnet is fixed on the opposite side of the gap plate on the bottom plate, the other magnet is fixed on the seesaw substrate, and the support portion is disposed on the gap plate side from the center of the seesaw substrate. It is characterized by that.

  According to the above configuration, since the balance is made by the magnet and the support portion is disposed on the gap plate side from the center of the seesaw substrate, when no books are displayed, the seesaw substrate is used as the bottom plate. Can be kept in parallel. When books etc. are displayed on a seesaw-type book stand, the seesaw-type book stand is inclined. Furthermore, when books etc. are displayed on the whole seesaw-type bookcase, the seesaw substrate can be kept in parallel with the bottom plate.

  The seesaw-type book stand of the present invention is excellent in functional beauty, and even if the inclination of the book stand is changed, it is possible to prevent slippage or loss of shape of a book, magazine, etc. without using a book end.

The width (W) of the seesaw substrate 11 and the width (W) of the back plate have the same length. The seesaw substrate 11, the side plates 12L and 12R, and the back plate 13 in the present embodiment use light paulownia materials (average specific gravity 0.25), but are not limited to this, and use similar light wood or resin materials. Also good.

  As shown in FIG. 2, the seesaw substrate 11 has a plurality of connecting holes 11a and 11b (two in this embodiment) so as to penetrate in the thickness direction (H). The connection holes 11a and 11b are formed in a rectangular shape when viewed from the top surface of the seesaw substrate 11, and are arranged side by side in the depth direction (D) so that the center in the left-right direction (W) is located on the same line.

  As shown in FIGS. 2 and 3, insertion holes 11c, 11d, and 11e for inserting a rotation shaft center rod 17 to be described later are circular in the front and back surfaces of the seesaw substrate 11, and the connection holes 11a and 11b. Is formed. As indicated by broken lines, the insertion holes 11c and 11d are formed so as to penetrate from the front surface or the back surface to the positions where the connection holes 11a and 11b are located, respectively. The insertion hole 11e is formed so as to penetrate the connecting hole 11a and the connecting hole 11b.

  As shown in FIG. 3, permanent magnets 21 and 23 are arranged on the bottom surface of the seesaw substrate 11. Specifically, as shown in FIG. 6, the permanent magnets 21 and 23 are arranged so as to be buried in the bottom surface of the seesaw substrate 11. The permanent magnets 21 and 23 are preferably strong permanent magnets. For example, strong permanent magnets such as neodymium magnets, samakoba magnets, and neodibond magnets are used.

  Returning to FIG. 1, the seesaw-type book stand 1 has a bottom plate 14 having the same size as the seesaw substrate 11 on the bottom side of the seesaw substrate 11. The gap plate 15 is positioned on one of the left and right ends (W) (on the right side in the document in this embodiment) so as to be sandwiched between the seesaw substrate 11 and the bottom plate 14. The gap plate 15 is fixed to the upper surface of the bottom plate 14. The bottom plate 14 and the gap plate 15 in the present embodiment use wood heavier than paulownia (for example, magnolia (average specific gravity 0.52)), but is not limited thereto, and uses similar wood or resin material. May be.

  As shown in FIG. 4, the bottom plate 14 has a plurality of support portions 16a and 16b (two in the present embodiment). The support portions 16a and 16b are formed in a rectangular shape when viewed from the upper surface of the bottom plate 14, and the upper portions thereof are rounded in the left-right direction (W), and the centers in the left-right direction (W) are located on the same line. Are arranged side by side in the depth direction (D).

  As shown in FIGS. 4 and 5, insertion holes 16 c and 16 d for inserting a rotating shaft rod 17 to be described later are formed in a circular shape on the front and back surfaces of the support portions 16 a and 16 b. As indicated by broken lines, the insertion holes 16c and 16d are formed so as to penetrate from the front surface to the back surface of the support portions 16a and 16b.

  As shown in FIGS. 4 and 5, a permanent magnet 22 is disposed on the upper surface of the bottom plate 14. A permanent magnet 24 is disposed on the bottom surface of the gap plate 15. Specifically, as shown in FIG. 6, the permanent magnet 22 is disposed so as to be buried in the upper surface of the bottom plate 14, and the permanent magnet 24 is disposed so as to be buried in the bottom surface of the gap plate 15. That is, after the step of burying the permanent magnet 24 in the bottom surface of the gap plate 15 is performed, the gap plate 15 is fixed to the upper surface of the bottom plate 14 so that the permanent magnet 24 is not exposed on the upper surface of the gap plate 15. As with the permanent magnets 21 and 23, the permanent magnets 22 and 24 are preferably strong permanent magnets. For example, strong permanent magnets such as neodymium magnets, samakoba magnets, and neodibond magnets are used.

  FIG. 6 is a front view showing the seesaw-type book stand 1 of FIG. As shown in FIG. 6, the seesaw substrate 11 is rotatably supported with respect to the support portions 16a and 16b by inserting the integral rotation shaft rod 17 in the order of the insertion holes 11c, 16c, 11e, 16d, and 11d. . In this embodiment, the rotation shaft center rod 17 is a wooden rod, but is not limited to this, and a seesaw using a rod made of bamboo, iron, resin, or the like may be used as long as it has sufficient strength. The substrate 11 may be supported.

  The support portions 16 a and 16 b are fixed at positions on the bottom plate 14 that are offset from the center in the left-right direction (W) of the seesaw-type book stand 1. That is, in this embodiment, the length from the support portions 16a, 16b to the side plate 12L in the left-right direction (W) is longer than the length from the support portions 16a, 16b to the side plate 12R, and the side plate 12L side is on the side plate 12R side. Heavier than For this reason, even in a state where no books or the like are displayed, the seesaw substrate 11 is tilted around the rotation axis 17 and the aesthetic appearance is impaired.

  Therefore, as shown in FIG. 6, the N pole of the permanent magnet 21 is placed on the side plate 12L side, and the N pole of the permanent magnet 22 is placed on the bottom side. That is, it arrange | positions so that the south pole of the permanent magnet 21 and the south pole of the permanent magnet 22 may oppose each other. Further, the N pole of the permanent magnet 23 and the N pole of the permanent magnet 24 are both arranged on the side plate 12R side. That is, it arrange | positions so that the south pole of the permanent magnet 21 and the north pole of the permanent magnet 22 may oppose each other. As a result, the seesaw substrate 11 and the bottom plate 14 are parallel to each other in a state where no books are displayed. Here, since the thickness (H) of the gap plate 15 is designed so that the seesaw substrate 11 and the bottom plate 14 are parallel to each other, the seesaw substrate 11 is located on the side plate 12R side around the rotation shaft center rod 17. There is no inclination to it.

  FIG. 7 is a front view showing a state in which a plurality of books 30 are leaned against the seesaw-type bookcase 1 of the present embodiment. As shown in FIG. 7, when the book 30 is displayed, the side plate 12 </ b> L side becomes heavier than the side plate 12 </ b> R side, so that the repulsive force between the permanent magnet 21 and the permanent magnet 22, the permanent magnet 23, and the permanent magnet 24 are generated. The forces attracting each other are insufficient, and the seesaw substrate 11 is tilted about 3 to 5 degrees with respect to the bottom plate 14 around the rotation shaft center rod 17. As a result, books and magazines can be leaned without slipping or losing shape without using a book end.

  Although illustration is omitted, the seesaw-type book stand 1 of the present embodiment approaches the state where the weight balance between the side plate 12L side and the side plate 12R side is not displayed when the book 30 is fully displayed to the side plate 12R side. Thus, the seesaw substrate 11 and the bottom plate 14 become parallel to each other again by the force of repulsion of the permanent magnet 21 and the permanent magnet 22 and the force of the permanent magnet 23 and the permanent magnet 24 attracting each other.

  The seesaw-type book stand of the present invention is excellent in functional beauty, evoke a sense of play by placing it indoors, etc., and can lean against books and magazines without slipping or losing shape without using a book end. It is expected to raise interest in the organization of books and books from children to adults.
