Description

  The present invention relates to a metal shelf and a metal wagon. In particular, the present invention relates to a beautiful metal shelf and wagon that can be easily assembled and disassembled, and that can reliably prevent the column from being inclined with respect to the shelf during use.

  A shelf made by assembling metal shelves and columns is generally called a steel shelf. Steel shelves are made by fixing multiple shelves between four columns. Such metal shelves are widely used for organizing and arranging various articles.

  On the other hand, a metal wagon can be made by attaching a caster below each column constituting the metal shelf. Such metal wagons are used in various ways. For example, it is used to carry tools and products in factories, to prepare materials and experimental tools in laboratories and transport them to the necessary places, and to carry food and tableware in cafeterias.

  Metal shelves and metal wagons intended for the above-described applications are generally open structures. The open structure is a structure having no walls at all, and can place an article on the shelf from any direction, and can take out the article on the shelf from any direction. As described above, such a structure is made up of a plurality of shelf boards and four support columns that support the shelf boards at four corners.

  The shelf with such a structure was disassembled when not in use and can be assembled at the place of use when in use. In addition, in order to reduce the weight of the shelf board and reduce the bending, the shelf board is formed into a shallow box shape and the thickness of the shelf board is made as small as possible. On the other hand, the column was made of angle steel and its width was small.

  As a result, the contact surface between the portion corresponding to the side wall of the shelf board and each piece of the angle steel occupies a small area, and it has been forced to be coupled with only one bolt and nut. However, when the abutment surface is coupled with only one bolt and nut in this way, there is a disadvantage that the column is easily tilted when the column of the shelf is pushed from the lateral direction. In particular, when a heavy object is placed on the shelf board, the column is tilted even if it receives a slight lateral force, and in extreme cases the shelf is crushed. This defect was particularly noticeable when casters were attached to the bottom of the shelf to form a wagon.

Japanese Patent No. 3437988 discloses means for improving the above-mentioned drawbacks. The means is that a small piece of metal plate is placed on the outside of the surface corresponding to the side wall of the shallow box-shaped shelf, and the side surface of the small piece of metal plate is positioned away from the corner by the length of the column. When assembling, the side face of the small metal plate abuts against the side face of the support column to prevent the support column from tilting. According to this means, it is possible to surely prevent the column from being inclined.
Japanese Patent No. 3437988

  However, it has been found that the means disclosed in the above patent are not satisfactory for metal shelves and wagons. This is because the metal plate pieces are attached to the outer surface of the shelf board, so that the shelf and the wagon are not good-looking products, and the metal plate pieces protrude from the outside of the shelf board. This is because it becomes difficult to handle these items neatly. In addition, since the metal plate piece is narrower than the width of the shelf side, the length of the contact surface where the shelf contacts the side of the column is smaller than the width of the shelf side. Therefore, a gap is likely to be formed on the contact surface, and therefore, a situation in which the inclination of the support column with respect to the shelf board cannot be prevented occurs. Thus, it has been found that such a problem needs to be solved.

  The present invention is intended to improve the above-mentioned problems of the proposal of Japanese Patent No. 3437988. That is, the present invention uses a means different from the above-mentioned patent to reliably prevent the support column from being inclined with respect to the shelf plate by simply fixing the support column and the shelf plate with a bolt. It is intended to facilitate the handling of the shelf board and improve the beauty of the shelf board.

  In order to solve the above-mentioned problems, the present invention adopts a method in which a side wall portion located at the corners of the four corners of a rectangular quadrilateral shallow box-like shelf board is cut out, and the side wall side surface caused by the notch is formed into an angle steel. The inscribed piece is attached to the inside of the side wall, the inscribed piece extends into the cutout portion of the side wall, and the supporting column is fixed to the inscribed piece with a bolt. To do.

  That is, the present invention comprises a plurality of right-angled quadrangular metal shelves and four struts made of angle steel, and the corners of the four corners of each shelf are in contact with the inner surface of the struts, In the metal shelf to be fixed and assembled by the above, the shelf board is formed by bending a metal plate, and is formed into a shallow box shape with four side walls standing from the bottom of a right-angled quadrilateral. The side walls located at the four corners are notched by the length of the column, and an inscribed piece extending in parallel with the side wall is fixed inside the side wall, and the inscribed piece extends into the notch. Further, the present invention provides a metal shelf characterized in that both sides of the support are sandwiched by side faces formed by side wall notches during assembly, and the support is fixed to the inscribed piece with bolts.

  Moreover, this invention provides the metal wagon which attaches a caster below each support | pillar in the said metal shelf. The wagon consists of a plurality of right-angled quadrilateral metal shelves and four struts made of angle steel. The corners of the four corners of each shelf are in contact with the inner surface of the struts, and bolts are used. In the metal shelf to be fixed and assembled, the shelf plate is made by bending a metal plate into a shallow box shape with four side walls rising from the bottom of a right-angled quadrilateral, and the four corners of the box The side wall located at the length of the column is cut out by the length of the column, an inscribed piece extending parallel to the side wall is fixed inside the side wall, and the inscribed piece extends into the notched portion, At the time of assembly, both sides of the support are sandwiched by the sides made by side wall notches, the support is fixed to the inscribed piece with bolts, and casters are attached below each support to make the metal shelf movable It is what.

  In the metal shelf according to the present invention, the shelf plate is formed by bending a metal plate, is formed into a shallow box shape with four side walls standing from the bottom of the right-angled quadrilateral, and is positioned at the four corners of the box. Since the side wall is cut out by the length of the width of the column, an inscribed piece extending in parallel with the side wall is fixed inside the side wall, and the inscribed piece extends into the notched portion. Since the inscribed piece is located on the inner side of the side wall, and therefore the surface is flush with the side wall, the shelf board is easy to handle and therefore the shelf board is easy to assemble, and the shelf Appearance is good. Also, since the side of the side wall made by the side wall notch is brought into contact with the side of the support and the support is sandwiched by the side of the sidewall, the support is sandwiched by the long side extending the entire height of the side wall, and accordingly. Inclination of the column with respect to the shelf board can be reliably prevented. The metal shelf according to the present invention provides the effects as described above.

  The metal wagon according to the present invention also has the same effect as the metal shelf.

  An embodiment of the present invention will be described with reference to the drawings as follows. FIG. 1 is a perspective view of a metal wagon according to the present invention. FIG. 2 is a perspective view of a shelf board used in the present invention. FIG. 3 is a developed view of the shelf board shown in FIG. FIG. 4 is a partially cutaway enlarged perspective view showing a connection relationship between the shelf board and the support column shown in FIG. 2. 5 to 8 are partially cutaway enlarged perspective views of other shelf boards that can be used in the present invention.

  FIG. 1 shows a metal wagon according to the present invention. In FIG. 1, A is a right-angled quadrilateral metal shelf, B is a support made of angle steel, C is a bolt fixing the shelf A to the support B, and D is a support B It is a caster attached below The metal wagon shown in FIG. 1 abuts the corners of the four corners of the shelf A on the inner side surfaces of the four columns B, and fixes each abutment surface with one bolt C. Each shelf board A is made between four support columns B to form metal shelves, and casters D are attached below each support column B.

  The shelf board A shown in FIG. 1 is formed into a shallow box shape by bending a metal plate as shown in FIG. In FIG. 2, the shelf A is formed into a shallow box shape by vertically raising four side walls 31, 32, 33 and 34 from the bottom 21 of the right quadrilateral. Each side wall 31, 32, 33 and 34 is notched at the four corners of the box by a length Q corresponding to the width of the column. Further, inscribed pieces 41, 42, 43, and 44 extending in parallel with the respective side walls are fixed inside the side walls 31, 32, 33, and 34, and each inscribed piece is placed in the notch of the side wall described above. It is extended.

  The shelf A shown in FIG. 2 is made by punching a metal plate into the shape shown in FIG. 3 and then bending the metal plate along a straight line shown by a dotted line in FIG. The punching plate F shown in FIG. 3 has side walls 31, 32, 33, and 34 each having a height of N on the four sides of a right-sided quadrilateral base 21 with L on one side and M on the other side. It is made by attaching inscribed pieces 41, 42, 43, and 44 each having a height P at the tip of the side wall. The height P is made smaller than the height N in the figure, but may be made larger. Each of the side walls 31, 32, 33 and 34 is notched only by a portion having a length Q along the side L or M from the corner of the bottom 21, thereby forming a notch R. On the other hand, the inscribed pieces 41, 42, 43 and 44 are not cut out and are kept in the length of one side L or M of the bottom 21.

  In the punched plate F shown in FIG. 3, first, the inscribed pieces 41, 42, 43 and 44 are folded back along the dotted lines in the same direction and overlapped with the side walls 31, 32, 33 and 34, respectively. Next, the side walls 31, 32, 33, and 34 are folded along the dotted line in the same direction as the inscribed pieces 41, 42, 43, and 44 are folded, and the side walls 31, 32, 33, and 34 are bent with respect to the bottom 21. Standing vertically. In this way, the shelf board A is configured by making the punched board F into a shallow box shape.

  When one of the corners of the shelf A shown in FIG. 2 is enlarged and shown, the structure shown in FIG. 4 is obtained. In FIG. 4, the shelf A has a box shape with side walls 32 and 33 standing around the bottom 21, and the side walls 32, 33 are newly cut out from the corners of the box by a length Q. 321 and 331 are formed, and a notch R is formed. Inside the side walls 32 and 33, inscribed pieces 42 and 43 extending in parallel with the side walls are fixed, and the inscribed pieces 42 and 43 extend into the notch R. At this time, the side surfaces 212 and 213 of the bottom 21 are positioned on the same plane as the inscribed pieces 42 and 43, respectively, or positioned on the inner side. On the other hand, the support B made of angle steel has an inner surface having a width of length Q.

  When the inner surface of the column B is brought into contact with the corner portion of the shelf A shown in FIG. 4, the length of the notch R is Q and the length of the inner surface of the column B is Q. B just fits into the notch R of the shelf A. Therefore, both side surfaces 51 and 52 of the column B come into contact with the side surfaces 321 and 331 of the shelf board A, respectively, and come into close contact with each other over the entire height of the side wall of the shelf board. After that, when bolts are fixed to the bolt holes 61 and 62 provided in the support column B and the bolt holes 420 and 430 provided in the inscribed pieces 42 and 43, respectively, the support column B is fixed by being sandwiched between the side surfaces 321 and 331. It will be.

  When the column B is fixed by being sandwiched between the side surfaces 321 and 331 of the shelf board A, the side surfaces 321 and 331 extend to the entire height of the side wall of the shelf board A. Since it receives the force which prevents an inclination over the full length of the thickness of the board A, it can prevent reliably inclining with respect to the shelf board A. Moreover, since there is no thing protruding outside from the side wall surface on the side wall surface of the shelf board A, the handling of the shelf board A is easy, so that the assembly and disassembly of the shelf becomes easy, and the appearance is also beautiful. Yes.

  2 to 4 show an example in which the inscribed piece is continuously connected to the side wall from the beginning, and the inscribed piece is formed only by bending the punching plate F. And may be attached to the side wall later. That is, the shelf board that can be used in the present invention is such that, for example, the inscribed pieces 71 to 75 are attached to the inside of the side walls 31, 32, 33, and 34 by spot welding like the shelf board G shown in FIG. It may be. Further, like the inscribed pieces 71 and 72, they may be separately provided on one side wall.

  Further, the inscribed piece may be not only a single layer but also a plurality of layers. That is, as for the shelf board which can be used by this invention, the inscribed piece 42 may be comprised by the two layers 421 and 422 like the shelf board H shown, for example in FIG. The inscribed piece 42 in FIG. 6 has inscribed pieces 421 and 422 connected to the end of the side wall 32. The inscribed piece 421 is first folded and overlapped with the inscribed piece 422 to form the inscribed piece 42. Then, the overlapped inscribed pieces 42 are further folded back inside the side wall 32.

  The inscribed piece provided on the inner side of the side wall may cover the entire inner side surface of the side wall, and may further extend along the bottom. The shelf board that can be used in the present invention is not only the inscribed piece 42 covering the inner surface of the side wall 32, for example, like the shelf board J shown in FIG. 7, but the tip 423 extends along the bottom 21. It may be.

  Further, the shelf plate that can be used in the present invention has the inscribed piece extending along the bottom, but may extend only a part of one side of the bottom. That is, in the shelf board that can be used in the present invention, the lower end 423 of the inscribed piece 42 may extend over one entire side of the bottom 21 like the shelf board K shown in FIG. Like the lower end 433 of the inscribed side 43, it may be cut in the middle extending along one side of the bottom to form a notch 434 so that the lower part of the side wall 33 is not covered.

  When the punched plate F having the structure as shown in FIG. 3 is made and bent into the shelf plate A shown in FIG. 2, the shelf plate can be made well. In particular, if each inscribed piece 41 to 44 is attached to each side wall as a series extending over the entire side wall, the bending of the bottom plate 21 can be reduced, so that the shelf plate with little bending even when a load is applied. Can be made. Among these, when the tip of the inscribed pieces 41 to 44 is extended along the bottom 21 as indicated by reference numeral 423 in FIG. 7, a shelf board with less bending can be obtained. In this respect, the present invention can provide a shelf board with high utility value.

  Further, the shelf boards A, G, H, J, and K can all be sandwiched between the columns B with the side walls facing upward, like the shelf board A shown in the middle and lower stages of FIG. Moreover, like the shelf board A shown in the upper part of FIG. If the side wall is fixed to the column B with the side wall facing upward, the shelf will be attached with spillage prevention on all sides, and if the side wall is fixed to the column B with the side wall facing downward, the shelf will not spill over. Become. A shelf board with a spill stopper is convenient for placing small articles, but it is inconvenient to take out the articles. On the other hand, shelves without spill protection are convenient for placing big things. Therefore, it is convenient that the form of the shelf and the wagon can be changed as necessary using the same shelf board.
