Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a book stand.

[0002]

[Prior art]

 As a general book stand, there is a book stand that is bent into an L-shape to form a pair of two pieces and applies them to both sides of a book arranged in a standing manner to prevent the book from falling down. This book stand is often installed on a bookshelf, so it is easy to deal with the increase or decrease of books. Also, a book stand, which is composed of a bottom plate on which books are placed, a back plate that supports the back of the books, and side plates that support both sides of the arranged books, is common, and is installed in an open space such as a desk.

[0003]

[Problems to be solved by the device]

 The above-mentioned book stand with a pair of L-shaped plates can easily cope with increase and decrease of books, but since both sides of the book are simply applied, the books arranged are unstable when used in an open space such as a desk. This tends to result in the need for a solid box-shaped frame such as a bookshelf or cabinet. On the other hand, a book stand consisting of a bottom plate, a back plate, and a side plate can stably arrange books on a desk, but cannot easily cope with the increase or decrease of books. Therefore, there is a means to accommodate the increase and decrease of books by installing a partition plate, but the lengths of the bottom plate and back plate are fixed. For this reason, even if the number of books is small, the entire book stand occupies an extra space, or a book stand of each size is required according to the storage space.

The present invention has been made in consideration of the above-mentioned problems, and can easily cope with increase and decrease of books, can be installed regardless of the size of the storage space, and creates an extra space even when there are few books. The purpose is to provide a book stand that does not allow it.

【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a book stand of the first embodiment, which is composed of a bottom portion 1, a back portion 2, side pipes 3 on both left and right sides, a partition portion 4, and a bottom support piece 5. The bottom portion 1 is formed by attaching four bottom pipes 7 between the left and right side end portions 6a and 6b. Similarly, the back portion 2 is also formed by attaching two back portion pipes 9 between the left and right side end portions 8a and 8b. The bottom pipe 7 is composed of left and right bottom pipes 7a and 7b which can be inserted into each other, and the back pipe 9 is also composed of left and right back pipes 9a and 9b which can be inserted into each other.

The left and right bottom pipes 7a and 7b and the left and right back pipes 9a and 9b are formed so that the outer diameter of one pipe is smaller than the inner diameter of the other pipe, as shown in FIG. Since they can be plugged into each other, the overall length can be expanded or contracted from the length of one pipe to the total length of the mutual pipes. In the figure, the left bottom pipe 7a is inserted into the right bottom pipe 7b, but the reverse is also possible. As shown in FIG. 2, the end of the pipe 7a (9a) is bent outward to increase the outer diameter, while the end of the pipe 7b (9b) is bent inward to increase the outer diameter. By making the pipe smaller, it is possible to further improve the usability by adopting a configuration that prevents the pipe from falling off when the pipe is stretched.

A hinge 10 is formed at each side end 6a, 6b, 8a, 8b of the bottom portion 1 and the back portion 2 so that the bottom portion 1 and the back portion 2 can be folded together. As a result, when not in use, it becomes a flat plate and can be stored compactly. The side pipe 3 is formed by bending a pipe material into a quarter circle shape or an elliptical shape, and both ends of the pipe 3 are provided at the respective side end portions 6a, 6b, 8a, 8b of the bottom portion 1 and the back portion 2. The stand can be easily installed by inserting it into the cut-out engaging hole and screwing with the screw 11, and the pipe 3 can be removed from the bottom 1 and the back 2 by the reverse operation, The bottom part 1 and the back part 2 can be folded into a flat plate shape.

The partition portion 4 is formed by forming a pipe material into a substantially fan-shaped frame, can be sandwiched between the back pipe 9 by the front and rear plates 12 a and 12 b and the screw 11, and can be attached to any position of the book stand. However, the mounting position can be easily changed. The number of partitions 4 can be set to one or more depending on the amount of books. FIG. 3 is a view showing a cross section of the bottom pipe and the bottom support piece 5.

As shown in FIG. 3, four arcuate pipe receivers 5 a are formed on the upper surface of the bottom support piece 5 so that four bottom pipes 7 can be placed. Can be supported near the central position to prevent the occurrence of bending. The bottom support piece 5 is particularly effective when the bottom pipe 7 is long or when the book is heavy. The number of bottom support pieces 5 mounted is not limited to one as shown in FIG. 1, and the number can be increased as necessary.

Although the side portion 3 is formed of a pipe material in the embodiment, it may be formed of a plate material, a net material, or a wire material. In this case, the length of the side portion 3 is expanded or contracted according to the amount of books to be placed. It is possible to form a book stand for this proposal. Next, another embodiment of the bottom portion will be described with reference to FIG.

As shown in FIG. 4, the bottom portion 1 is composed of two left bottom plates 13a and a right bottom plate 13b that form a pair on the left and right. The left bottom plate 13a has a simple plate shape, but the right bottom plate 13b has both sides folded back so that the left bottom plate 13a is inserted into the right bottom plate 13b. As a result, the pipes can be inserted into each other in the same manner as the operations of the pipe mechanisms having different diameters described above, so that the horizontal length of the book stand can be appropriately changed.

Further, as long as they are formed so as to be insertable into each other, they may be constituted by rods in addition to pipes and plates, and those materials may be metals, plastics, wood, etc. . Furthermore, it goes without saying that the other embodiments described for the bottom portion 1 are similarly applicable to the back portion 2.

Next, another embodiment of the partition section 4 will be described with reference to FIG. As shown in FIG. 5, the partition part 4 is a partition plate 14 of a plate material. Further, the partition plate 14 can use not only the flat plate shown in FIG. 5 but also mesh members, rods, wires and the like. The means for attaching / detaching the partition plate 14 to / from the back portion 2 is not limited to the screw plate. For example, as shown in FIG. 5, the mounting portion 15 is also made of rubber, which is an elastic material, synthetic resin or the like in an arc shape so that the back pipe 9 can be held and detached. Other types of attachment / detachment means, such as a spring type clip and a magnet, can also be used.

[0022]

[Effect of device]

 As described above, according to the present invention, since the bottom portion and the back portion can be freely expanded and contracted, it is possible to change the length of the entire book stand with respect to the increase or decrease of books. As a result, when the number of books is small, the length can be shortened to make a compact book stand, and when the number of books is increased, the length can be increased to accommodate it, which is very convenient.

When pipe materials are used for the bottom and the back, the weight can be reduced. When the bottom support piece is arranged on the lower side of the bottom portion, it is possible to prevent the occurrence of bending even if the bottom portion becomes long. The stability of the placement of books can be increased by using plates for the bottom and back.

Since the detachable partition section is provided, it is possible to easily deal with increase and decrease of books. When the partition section is made of pipe material and can be attached to and detached from the back pipe by a screw plate, the weight of the partition section can be reduced and the partition can be easily attached and detached. The bottom part and back part are joined by hinges so that they can be folded, and the side parts can be attached and removed freely, so they can be stored compactly when not used as a book stand.
