Abstract

(57) [Summary] [Purpose] To provide a book stand that is manufactured in large quantities with a small number of parts, has a minimal number of parts, is inexpensive, is easy to assemble and disassemble, and is convenient to carry. [Structure] Narrow plate-shaped sliding guide pieces 22 to 27 of one side surface portion of a side wall portion 21 are inserted into a ring 31 of a base portion of a side plate member 3 to form one side of a book stand. Two of these are prepared, the side plate members 3 face each other with the respective sliding guide pieces 22 to 27 inside, and the sliding guide pieces 22 to 27 are overlapped with each other to form the book stand 1. The guide rails 28 provided on the sliding surface sides of the sliding guide pieces 22 to 27 allow the sliding guide pieces to slide smoothly without shifting. Further, the stoppers provided at the end portions of the sliding guide pieces 22 and 27 prevent the bottom plate members 2 from being separated from each other in the left-right direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a book stand whose width can be changed.

[0002]

[Prior art]

 Conventionally, as a book stand whose width can be changed, a wooden one as shown in Fig. 5 has been commercially available. This is like a combination of two bookshelves, and the back support plates 46 to 47 and the bottom plates 48 to 52 are slidably provided alternately, and the side plate portions 42 to 45 are widened to the left and right to adjust the width. .

[0003]

[Problems to be solved by the device]

 However, as for the component parts, four side plates are required, and at least four bottom plates are required from the practical point of view, and the processing was troublesome. Also, the mechanization of the assembly was difficult, and it could only be done by human hands, which took time and effort. Moreover, since the side plate and the bottom plate are fixed with nails, screws, and adhesives, it is difficult to disassemble, and even if the width is minimized, it was bulky and difficult to carry.

The present invention was devised in view of the above problems. It is manufactured in large quantity with a small number of parts, the number of parts is reduced as much as possible, the cost is low, and the assembly and disassembly are easy. The purpose is to provide a book stand that is convenient to carry.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the book stand of the present invention is a book stand composed of two bottom plate members and a side plate member forming a partition and an end, and one side surface portion of a side wall portion of the bottom plate member. A narrow plate-shaped sliding guide piece is formed at different vertical positions so that the sliding guide pieces are vertically overlapped with each other so that the bottom plate members can slide in the left-right direction. A guide rail is provided on the sliding surface of the sliding guide piece, a stopper is provided at the end of the sliding surface, and the side plate member is erected so as to be slidable on the sliding guide piece.

[0006]

[Action]

 According to the above book stand, the side plate members are erected at the ends of the two bottom plate members, respectively. Then, the two bottom plate members are combined so that the sliding guide pieces formed at the upper and lower different positions on the one side surface of the side wall portion of the bottom plate member overlap vertically. The guide rails protruding from the vertically overlapping sliding guide pieces allow the bottom plate members to slide stably in the left-right direction. Also, when adjusting the width of the stand by holding the side plate member, even if the bottom plate member is pulled too much to the left or right, the stoppers provided at the end of the sliding surface of the sliding guide piece will be caught and more The width does not spread. A side plate member for partitioning will be provided if necessary.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment. 1 is a perspective view of a book stand according to an embodiment of the present invention with a minimum width, FIG. 2 is a sectional view taken along the line AA of FIG. 1, FIG. 3 is a perspective view of the book stand of FIG. FIG. 4 is a perspective view of a bottom plate member alone of a book stand according to an example of the present idea.

In FIG. 1, 1 is a stand, 2 is a bottom plate member integrally molded with synthetic resin, and 3 is a side plate member similarly molded integrally with synthetic resin. As shown in FIG. 4, the bottom plate member 2 has six narrow plate-shaped sliding guide pieces 22 to 27 formed on one side surface portion of the side wall portion 21 so as to project at different vertical positions. Further, the guide rail 28 is provided on the facing surface side of the sliding guide pieces 22 to 27 which are formed to alternately project above and below the side wall portion 21, and the width thereof is, as shown in FIG. The inner width of the rail is equal to the outer width of the lower rail. Further, a stopper 29 for preventing the bottom plate member 2 from splitting in the left-right direction is provided at the end of the sliding guide piece 22 and the sliding guide piece 27 on the same side as the guide rail 28. There is. Here, the side plate member 3 is formed by providing a side plate 32 on a rectangular ring 31 as shown in FIG.

The book stand 1 according to the embodiment of the present invention is composed of five parts, which are two bottom plate members 2 and three side plate members 3. The sliding guide pieces 22 to 27 are inserted into the ring 31 of the side plate member 3 and the ring 31 is moved to the base of the sliding guide pieces 22 to 27. The bases of the sliding guide pieces 22 to 27 have a role of reinforcing and a role of restraining the ring 31 of the side plate member 3, and are sized to fit on the inner surface of the ring 31. This is the right side plate of the book stand 1. Similarly, the side plate member 3 is attached to the other bottom plate member 2 to form the left side plate. If a partition is required, insert the required number of slide guide pieces 22 to 27 before stacking the slide guide pieces.

After the side plate members 3 have been attached to the left and right bottom plate members 2 and 2, as shown in FIG. 3, the end portions of the slide guide piece 22 and the slide guide piece 27 are overlapped with each other, and along the guide rail 28. Push in to adjust the width of the book stand 1. Then, the position of the side plate member 3 for partitioning is adjusted. Even if the bottom plate members 2 are separated from each other too much, the sliding guide pieces will not come off due to the stoppers 29 provided at the ends of the sliding guide pieces 22 and the sliding guide pieces 27.

When the main stand 1 is disassembled and carried, the slide guide piece 22 and the slide guide piece 27 are separated from each other vertically, and the bottom plate members 2 and 2 are divided into the left and right in the reverse order of the assembly, and the middle partition is used. The side plate member 3 for the end portion is pulled out from the sliding guide pieces 22 to 27, and is stacked and carried.

[0012]

[Effect of device]

 As described above, the book stand of the present invention is composed of two kinds of members, the bottom plate member and the side plate member, and can be manufactured at low cost by mass production. In addition, since there are only two bottom plate members and only side plate parts, the number of parts is small, and they can be assembled simply by inserting them and disassembled simply by removing them. Disassembling makes it convenient to carry without being bulky.

Further, in the book stand of the present invention, the partition can be provided at a desired position as needed. In addition, the guide rail allows smooth width adjustment, and the stopper does not divide the book stand into two parts.
