Description

  The present invention relates to a book end used for standing books and arranging them.

  Bookends are tools that have been used for a long time to stand books in a standing state, and now they have a simple design that emphasizes practicality, and are rich in decoration. A variety of bookends with various shapes, structures, and materials have been proposed and put to practical use.

  Among them, for example, as shown in FIG. 9, a book end 10a, 10b having a shape in which the center of a single metal plate is punched in an inverted U shape, and its peripheral portion is bent at a right angle with respect to the punched inverted U shape portion. The structure is simple and can be easily manufactured, and at the time of storage, a plurality of bookends can be stacked compactly with the protruding parts in the same U-shape aligned in the same direction. High and frequently used.

  However, this type of book end also has weaknesses, and one or more books are taken out from the books held in a standing state between the pair of left and right book ends 10a, 10b when necessary. As a result, the remaining books lose their support and lean to the left or right and lean against the side plate of the book end. As a result, either the left or right book end or both book ends slide sideways toward the opposite side of the book, that is, backward. There is a problem that.

  In order to solve this problem, for example, in Patent Documents 1 to 3, it is proposed that a slip stopper is attached to the bottom surface of the book end. If a non-slip is attached to the bottom surface of the book end, the book end certainly does not skid when the book is taken out, and the remaining books can be stably held between the book ends.

  However, according to the knowledge obtained by the present inventor, the book end with a non-slip attached to the bottom surface is arranged on the book side, that is, in front of the book end in order to eliminate the space generated in the removal mark after the book is taken out. If you try to move the book end, the anti-slip attached to the bottom will resist the movement in this direction, and if you press the side plate of the book end with one hand, the book end will not slide sideways toward the front. Have difficulty. For this reason, in order to move the book end with a non-slip attached to the bottom of the bottom plate toward the book side, it is necessary to lift the book etc. with one hand while pushing the book end with the other hand to move it. You will need it. As described above, the attachment of the anti-slip results in inconvenience that it is returned and becomes unusable.

  The present invention was made in order to eliminate the disadvantages of both the conventional non-slip type and non-slip type book ends. It is an object of the present invention to provide a book end that can be stably held with one hand and can be easily slid with one hand in order to eliminate the space generated in the trace of taking out the book.

  As a result of repeated trial and error to solve the above problems, the inventor acts on the book end when taking out the book, etc., and the book end, etc. It was found that the force applied to the book end mainly acts at different positions on the bottom plate of the book end when trying to skid the book end forward to eliminate the space left in the take-out trace. . Based on this knowledge, the present inventor has provided a non-slip only on the bottom surface of the bottom plate on which the force to try to skid the book end backward acts mainly, and tried to skid the book end forward. It was confirmed that the above problems could be solved at once by not providing a slip stopper on the bottom surface of the bottom plate on which the force applied to the book end mainly acts, and the present invention was completed.

  That is, the present invention includes a bottom plate and a side plate that rises substantially perpendicular to the bottom plate, and the bottom plate exists on both the front and rear sides of the side plate, and on the bottom plate portion that exists in front of the side plate. A book end for placing and using books, etc., when the portion of the bottom plate that exists in front of the side plate is a front bottom plate portion, and the portion that exists behind the side plate is a rear bottom plate portion, The above problem is solved by providing a book end in which the bottom surface of the front bottom plate portion is not provided with a slip stopper and the bottom surface of the rear bottom plate portion is provided with a slip stopper.

  According to the knowledge independently obtained by the present inventor, when books or the like arranged between book ends are inclined, the force to try to slide the book ends backward, that is, toward the opposite side of the books is mainly. It acts on the bottom surface of the rear bottom plate portion, and if a slip stopper is provided here, it is sufficient to prevent a side slip when taking out the book. On the other hand, when the side plate is pushed to slide the book end forward, that is, toward the book side, in order to eliminate the space generated in the takeout mark of the book etc., the force acts mainly on the bottom surface of the front bottom plate part. It is. Nonetheless, the bottom of the book end was considered to be all homogeneous, and the anti-slip was attached to the bottom of the front bottom plate part. is there. In the book end of the present invention, as described above, since the anti-slip is not provided on the bottom surface of the front bottom plate portion, a force is applied to the side plate from the outside even when a book or the like is present on the bottom plate. Thus, the book end can be easily slid forward with one hand.

  In a preferred embodiment, the book end of the present invention is a central bottom plate in which the portion of the bottom plate that is positioned in front of the book end with respect to the rear bottom plate portion and behind the book end with respect to the front bottom plate portion. When it is a part, it is a book end in which a slip stopper is not provided on the bottom surface of the central bottom plate part. The bottom surface of the central bottom plate portion corresponds to a region directly below the side plate and also corresponds to a region obtained by extending the region directly below the side plate in the horizontal longitudinal direction of the side plate. It is a place that becomes a fulcrum when a force is applied to the side plate. Therefore, if the anti-slip is not provided in this place, the bookend can be more easily slid forward.

  The book end of the present invention is basically used as a pair of left and right with the front bottom plate portions facing each other, like the conventional book end. However, the book end of the present invention may be used alone and may be used so as to support a book or the like only on one side surface thereof, or may be used in combination of three or more in an appropriate direction. In any case, it may be used in such a direction that the front bottom plate portion on which a book or the like is placed during use is inward.

  In addition, there is no special restriction | limiting in the object hold | maintained by the book end of this invention, For example, a book, a book, a magazine, a catalog, a brochure, other printed matter, a document, etc. may be sufficient.

  The book end of the present invention can be used even when one or more required books are taken out from books placed side by side, even if the remaining books are tilted and lean against the side plate of the book end. Has the advantage that it will not slide backwards and the remaining books will not fall down, and the side plate of the book end should be It has an advantage that the book end can be easily slid forward and toward the book by simply pushing with one hand.

It is a figure which shows an example of the use state of a book end. It is a figure which shows an example of the use state of a book end. It is a right view which shows another example of the book end of this invention. It is a bottom view of a book end. It is a perspective view which shows an example of the conventional book end.

  Hereinafter, the present invention will be described in detail with reference to the drawings, but the present invention is not limited to the illustrated one.

  FIG. 1 is a perspective view showing an example of a book end according to the present invention. In FIG. 1, 1 is a book end, 2 is a bottom plate of the book end 1, and 3 is a side plate of the book end 1. As shown in FIG. 1, the book end 1 of this example is formed by punching a substantially central portion of a flat plate member into an inverted U shape, and forming a punched inverted U-shaped portion and its root portion as a bottom plate 2. 2 is a book end having a shape in which a peripheral portion of an inverted U-shaped portion is bent at a right angle to form a side plate 3, and its basic shape itself is not different from the conventional book ends 10a and 10b shown in FIG. .

  Reference numeral 4 denotes a reinforcing bent portion provided in a straight line continuously from the side plate 3 to the bottom plate 2. Since the bent portions 4 are provided on the left and right sides of the side plate 3, the strength of the side plate 3 is increased, and the side plate 3 can always be kept upright to the bottom plate 2 even when a relatively large external force is applied. it can. The bent portion 4 is not essential for the book end 1 of the present invention, but is preferably provided to reinforce the strength of the side plate 3.

  There are no particular restrictions on the material that constitutes the book end 1, and it is sufficient to use materials that are usually used for the book end of the type. Metals such as iron, copper, and brass, plastics, etc. It can be configured using an appropriate material.

FIG. 2 is a plan view of the book end 1. As shown in FIG. 2, the bottom plate 2 extends on both sides of the side plate 3, and when used as a book end, the side on which the books B ₁ , B ₂ , B ₃ are placed, Assuming that the front side is α and the opposite side is the rear side β for convenience, the bottom plate 2 exists on both the front α side and the rear β side of the side plate 3.

  In FIG. 2, a region 2 f that is hatched to the right is a front bottom plate portion that exists on the front α side of the side plate 3 of the bottom plate 2, and a region 2 r that is hatched to the left is the bottom plate 2. This is a rear bottom plate portion existing on the rear β side with respect to the side plate 3. Since the side plate 3 has a thickness, the front bottom plate portion 2f and the rear bottom plate portion 2r are usually not continuous, and a central bottom plate portion 2c exists as an area corresponding to the thickness of the side plate 3 between them. To do. That is, the center bottom plate portion 2c corresponds to a region immediately below the side plate 3 and a region obtained by extending the region immediately below in the horizontal longitudinal direction of the side plate 3 (the direction perpendicular to the front-rear direction and the vertical direction in FIG. 2). It is the bottom plate part.

  3 is a right side view of the book end 1, and FIG. 4 is a bottom view. 3 and 4, 5 is a non-slip. As shown in FIGS. 3 and 4, the anti-slip 5 is provided over the entire bottom surface of the rear bottom plate portion 2r, but is not provided on the bottom surface of the front bottom plate portion 2f. Further, the anti-slip 5 is not provided on the bottom surface of the central bottom plate portion 2c. As described above, the anti-slip 5 is provided on the bottom surface of the rear bottom plate portion 2r, but the anti-slip 5 is not provided on the bottom surface of the front bottom plate portion 2f and the bottom surface of the center bottom plate portion 2c. This is a feature of the book end 1 according to the above.

5 and 6 are diagrams illustrating an example of a usage state of the book end 1 illustrated in FIGS. 1 to 4. FIG. 5 shows a state in which several books are taken out from a plurality of books arranged between the pair of book ends 1. As a result of taking out several books from the state in which they are closely aligned, the remaining books become unstable and fall down toward the side plate 3 of the book end 1 as shown by the arrows in the figure. Since the slip stopper 5 is provided on the bottom surface of the rear bottom plate portion 2r of the book, the book end 1 does not slide backward, and the books B ₁ , B ₂ , and B ₃ that have fallen on the side plate 3 are securely attached on the spot. Can support.

On the other hand, in FIG. 6, from the state shown in FIG. 5, in order to eliminate the space generated by removing the book, a force is applied to the side plate 3 to slide the book end 1 forward, that is, in the direction in which the book exists. Indicates the state. As shown in FIG. 6, although the anti-slip 5 is provided on the bottom surface of the rear bottom plate portion 2r of the book end 1, no anti-slip is provided on the bottom surfaces of the front bottom plate portion 2f and the intermediate bottom plate portion 2c. By simply pushing the side plate 3 toward the front of the book end 1 with one hand, the book end 1 uses the bottom surface of the front bottom plate portion 2f as a sliding surface and the books B ₁ and B placed on the front bottom plate portion 2f. _2, B ₃ smoothly skidding with, it is possible to eliminate the space created by removing the book.

  The material of the anti-slip 5 is not particularly limited, and a sheet-like or thin-layer material having a relatively large friction coefficient such as rubber or synthetic resin may be used as the anti-slip. The means for providing the anti-slip 5 at an appropriate position on the bottom surface of the bottom plate 2 is not limited. For example, the sheet-like or thin-layer anti-slip 5 may be bonded or pasted using an adhesive or glue. .

  FIG. 7 is a right side view showing another example of the book end 1 according to the present invention, and FIG. 8 is a bottom view of the book end 1 shown in FIG. The book end 1 of this example is different from the example described above in that the anti-slip 5 is provided not on the entire bottom surface of the rear bottom plate portion 2r but on a part of the bottom surface of the rear bottom plate portion 2r. ing.

  As shown in FIGS. 7 and 8, in the book end 1 of this example, the front tip surface of the anti-slip 5 is located rearward by a distance d from the front tip surface of the rear bottom plate portion 2r. As described above, when the front end surface of the anti-slip 5 provided on the bottom surface of the rear bottom plate portion 2r is located behind the front front surface of the rear bottom plate portion 2r by a distance d, the side plate 3 is pushed to push the book end. When 1 is slid to the front α side, there is less resistance due to the anti-slip 5 and the book end 1 can be slid more smoothly to the front α side, that is, the side where the book exists. can get.

  The value of d may be d> 0, but is preferably equal to or longer than the length of the central bottom plate portion 2c, that is, the length in the α-β direction. More than twice the length is more preferable. However, the value of d is preferably equal to or less than (1/2) of the length in the front-rear direction of the rear bottom plate portion 2r, that is, the length D in the α-β direction.

  It is desirable that the rear end surface of the anti-slip 5 coincides with the rear end surface of the rear bottom plate portion 2r. When the rear end surface of the anti-slip 5 is coincident with the rear end surface of the rear bottom plate portion 2r, the force applied to the side plate 3 by the falling book is more reliably received by the anti-slip 5, and the book end 1 It is possible to more effectively prevent backward slipping.

  On the other hand, the length L in the width direction of the book end 1 of the anti-slip 5, that is, the direction orthogonal to the α-β direction may be shorter than the length H in the width direction of the rear bottom plate portion 2 r of the bottom plate 2. <H. However, the width direction length L of the anti-slip 5 is longer than the width direction length W of the front bottom plate portion 2f protruding in a tongue shape, and it is preferable that L> W. Since the book end 1 according to the present invention is generally symmetrical with respect to the center line in the width direction of the book end 1 including the anti-slip 5, if L> W, the front bottom plate portion 2 f is In length, it will be completely contained by the anti-slip 5. Moreover, when the book end 1 has the bending part 4 for reinforcement, it is preferable that the length L of the anti-slip 5 in the width direction includes both the two bending parts 4.

  As with the book end 1 of this example, as described above with reference to FIGS. 5 and 6, it is difficult to slide backward, and it is possible to firmly receive and support books that fall over and forward. It is easy to slip, and an excellent effect that the space generated by taking out a book or the like can be easily eliminated by one-hand operation is obtained.

  As described above, according to the book end of the present invention, it is possible to stably hold the remaining book even when the book is taken out, and to fix the book end to the book side so as to eliminate the space generated after the book is taken out. Since it can be easily slid, the book or the like can be held and managed in an extremely simple state. The present invention exerts its power in the display, storage and management of books and magazines in a standing state in a library, a bookstore, etc., and its industrial applicability is great.
