Description

  The present invention relates to a metal shelf and a metal wagon. In particular, the present invention relates to a metal shelf and a metal wagon that can be easily assembled and disassembled, and can easily prevent the column from being inclined with respect to the shelf board by a simple operation.

A metal shelf is generally called a steel shelf. This shelf is formed by bending a metal plate to form a column and a shelf plate, which are assembled into a shelf. The metal wagon is said to be a steel wagon, and a caster is attached below the column constituting the metal shelf so that the metal shelf can be moved.
Various metal shelves and metal wagons have been proposed. In many cases, a metal plate bent into a shallow box shape is used as a shelf plate, and a metal plate bent into an angle shape is used as a support column.

  More specifically, the above shelf plate is formed by bending a metal plate to form a flat bottom and four side walls standing up from now on, and forming a shallow rectangular box as a whole. Some of the shelves also have a structure in which the end of the side wall is folded back inward or outward, the folded part is extended in parallel with the side wall, and the side walls are doubled. . Therefore, in the shelf board, the four side walls or the outer surfaces of the folded portions form the side face of the shelf board. On the other hand, the column is composed of a long body obtained by bending a metal plate into an angle. Some of the pillars are simply L-shaped in cross section, and edge pieces projecting further inwardly are attached to both ends of L to form small inward grooves on both sides. In some cases, a narrow slope is formed along the L fold. The shelf board and support | pillar used by this invention include such a thing.

  In order to make a shelf by combining the shelf plate and the column as described above, the column is raised, the corners of the four corners of the shelf are brought into contact with the inner surface of the column, and the contact part is fixed with a bolt. Yes. In this case, in order to facilitate the assembly to the shelf and to easily place the article on the shelf, a column having a narrow width and a shelf plate having a low side wall are used. Accordingly, the contact area between the shelf board and the support column is small, and this contact surface must be coupled with a small number of bolts. As a result, the coupling between the shelf board and the column is easily wobbled, and therefore the column is easily inclined with respect to the shelf board. Therefore, the assembled shelf is easily twisted. Various attempts have been made to fix the column and the shelf so as to solve this problem.

  In Japanese Patent No. 3437898, a small piece of a metal plate is attached on the outer surface of the side wall of the box-shaped shelf board at a distance from the corner of the shelf board so that the edge of the small piece abuts the side surface of the column. Discloses a means for preventing the column from tilting with respect to the shelf. According to this means, since the edge of the metal plate piece sandwiches both side edges of the support column, the support column can be prevented from being inclined with respect to the shelf plate. However, since this means lacks a means for temporarily locking the shelf board to the support column at the beginning of the assembly, the shelf board is easily slipped on the surface of the support column, and therefore, the assembly is not easy.

Utility Model Registration No. 3085475 is provided with a locking projection that protrudes inwardly on an angled column, a locking hole is provided in the corner of the shelf, and the locking projection is inserted into the locking hole. Propose to lock the shelf to the column. However, this proposal discloses, as a specific example of the locking projection, that the support column is provided with two parallel cuts extending perpendicularly to the longitudinal direction, and an intermediate portion of the cut is pushed out to form a chevron-shaped locking projection. There are only. In this case, the locking projection only serves to prevent the shelf board from falling. In other words, this locking projection cannot prevent the column from tilting with respect to the shelf board.

  Japanese Patent No. 4473095 describes means for preventing the support column from being inclined with respect to the shelf board as in the above-mentioned Japanese Patent No. 3437988. That means is to cut out the corners of the side walls of the shelf, and abut the side walls of the side wall against the side of the column to prevent the column from tilting with respect to the shelf. Since this means also lacks a means for locking the corner of the shelf to the support at the beginning of assembly, the shelf is easily slid on the surface of the support, and therefore is not easy to assemble.

Japanese Patent Application Laid-Open Nos. 2008-36117 and 2008-36118 both describe means for fixing the corners of the shelf boards at arbitrary positions on the columns. However, as a fixing means, a hollow complex column having a slit-like opening is used as a column, a female screw piece is inserted into this column, a corner fixing piece is attached to the corner of the shelf, and the corner fixing unit is attached. The bolt is fixed from one piece to the female screw piece. This means requires two auxiliary tools, a female screw piece and a corner fastening piece, which is complicated and it is not easy to fix the shelf to the column.
Thus, until now, it has been difficult to lock the shelf to the column at the beginning of assembly, and it has been difficult to reliably prevent the column from tilting with respect to the shelf by simple operation. was there.

  The present invention has been made to solve the above problems. In other words, the present invention is a metal that can easily lock the corner of the shelf to the column at the beginning of assembly, and can prevent the column from tilting with respect to the shelf simply by fixing with bolts. A shelf is provided. The present invention also provides a metal wagon made so that the metal shelf can be moved by attaching a caster to the lower side of the support column of the metal shelf.

  The present invention will be briefly described as follows based on an example of implementation. First, as shown in FIG. 1, the right side quadrilateral metal plate piece is fixed to the inner side surface of the column B to provide the right side quadrangle protrusion 1 and the upper edges 11 and 111 are arranged in the longitudinal direction of the column. The descending edges 13 and 131 are oriented parallel to the longitudinal direction of the column. On the other hand, in the case of the shelf A, two cuts parallel to the shelf surface are formed on the side surface in contact with the support column, and a cut perpendicular to the cut is made at the back of the cut, so that the metal plate piece is projected. A right-handed quadrilateral notch 2 into which 1 can be inserted is provided.

At the time of assembly, the support B is set up, the shelf A is held almost horizontally and brought close to the support B, and the shelf A is moved to the arrow while the one side wall 21 of the shelf A is first brought into contact with the inner surface of the support B. Protruding portion 1 is inserted into the cutout 2 in the side wall 21 while proceeding in the E direction. Then, the shelf board A is locked to the support column B because the upper edge 22 of the notch 2 is supported on the upper edge 11 of the protrusion 1.
When the shelf A is further moved in the direction of arrow E in this state, the protruding portion 1 is inserted into the cutout 2 of the side wall 211, and the upper edges 22 and 221 of the cutout 2 are respectively connected to the upper edge 11 of the protruding portion 1. And 1
11 and close. At the same time, the drooping edges 24 and 241 of the notch 2 come into close contact with the descending edges 13 and 131 of the protrusion 1, respectively. Accordingly, the protrusion 1 brings the upper edges 11 and 111 into close contact with the upper edges 22 and 221 of the notch 2, respectively, and the descending edges 13 and 131 on both sides of the upper edge are respectively connected to the hanging edge 24 of the notch 2. 241 is brought into intimate contact.

  Thus, since the protrusion 1 is inserted into the notch 2 in close contact with edges in three directions perpendicular to each other, the protrusion cannot move in the notch. Accordingly, the shelf board A is locked in a state in which it cannot move with respect to the column B. Thus, the gist of the present invention is to firmly connect the shelf board A to the column B.

  Generally, when overlapping metal plates, dowels are attached to determine the overlapping position. That is, a protrusion is provided on one plate, a recess is provided on the other plate, the protrusion is inserted into the recess, and the plate is locked. However, many dowels are small and their shapes are not precisely defined. Therefore, it is completely different from a dowel to provide a right-angled quadrilateral projection as described above, to make the edge straight, to determine the direction in which the straight line is directed, and to be in close contact over a considerable length of the edge. ing.

  In the example described above, a small metal plate piece is prepared and fixed to the inner side surface of the support by welding or the like, but the metal plate piece may not be prepared separately. Since the present invention requires an edge of the protrusion made of a small piece of metal plate, the protrusion can be made by extruding a part of the column, or provided by cutting up a part of the column. Can do.

  Further, when the metal plate piece is a right-angled quadrilateral as described above, among the protrusions made by the metal plate piece, what is required is the upper edge and the falling edges 13 and 131 located on both sides thereof as described above. And the remaining lower edge may be any shape, for example, two folded edges. The reason is that when the shelf board is attached to the support column, the shelf board descends due to its own weight, so the upper edge of the notch is supported by being in contact with the upper edge of the protrusion, so the lower edge does not have to be in close contact. Because. Rather, it is preferable that the lower edges are not in close contact with each other because the protruding portion can be easily fitted into the notch. However, if the shelf board is turned upside down so that it can be used by being fixed to the column, it is necessary to make the lower edge of the shelf board close to the upper edge of the column protrusion. . Moreover, the metal plate piece and the notch are not limited to one in each corner of the shelf plate, and may be provided in two or more.

  In the description so far, the shape of the protrusion is a right-angled quadrilateral, but the shape of the protrusion is not limited to a right-angled quadrilateral. The shape of the protrusion can be a polygon such as a hexagon or an octagon. In the case of a hexagon, an octagon, etc., it is preferable that a regular hexagon or a regular octagon is extended in the direction in which one side of the regular hexagon or regular octagon is extended. In this case, it is preferable that the column is attached to the column with the extended direction directed in the longitudinal direction of the column. That is, it is preferable that the polygonal edge extending in the longitudinal direction of the support column is longer than the edge extending in the width direction of the support column.

  Thus, according to the present invention, a metal plate is bent into a right rectangular quadrilateral shallow box shape and a metal plate is bent into an angled column, and the column is raised to form four corners of the shelf plate. In metal shelves that are assembled by abutting the corners on the inner side of the column and fixing the abutting part with bolts, a polygonal protrusion is provided on the inner side of the column that contacts the shelf, and the side of the shelf that contacts the column A notch into which the protruding portion can be inserted is provided, and when the shelf is assembled, the protruding portion of the column is inserted into the notch of the shelf plate, the upper edge of the notch is brought into close contact with the upper edge of the protruding portion, and the upper edge of the notch is A metal shelf, characterized in that two drooping edges located on both sides and extending downward are brought into close contact with two descending edges extending downward of the protrusion, and the corner of the shelf abuts against the inner surface of the column. It is to provide.

  In addition, the present invention provides a metal wagon in which a caster is further provided below the support in the metal shelf to facilitate the movement of the metal shelf. The metal wagon is composed of a shelf plate that is bent into a rectangular box by bending a metal plate and an angled column that is bent from a metal plate. In metal shelves that are assembled by abutting the corners on the inner side of the column and fixing the abutting part with bolts, a polygonal protrusion is provided on the inner side of the column that contacts the shelf, and the side of the shelf that contacts the column Provided with a notch into which the above protrusion can be inserted, and when the shelf is assembled, the protrusion of the column is inserted into the notch of the shelf plate so that the upper edge of the notch is in close contact with the upper edge of the protrusion and both sides of the upper edge of the notch Two drooping edges that are located at the bottom and are in close contact with the two descending edges that extend below the protrusion, and the shelf corners abut against the inner surface of the column to form metal shelves. A caster is attached to the main body.

  According to this invention, since the polygonal protruding portion is provided on the inner side surface of the support column in contact with the shelf plate, and the notch into which the protruding portion can be inserted is provided on the side surface of the shelf plate in contact with the support column, the protruding portion is provided at the beginning of assembly. A shelf board can be locked to a support | pillar only by inserting in a notch.

  The shape of the notch is such that, when the shelf is assembled, the upper edge located above the notch is in close contact with the upper edge located above the protrusion, and the two hanging edges are located on both sides of the upper edge of the notch and extend downward. When the protrusion is inserted into the notch, the upper edge of the protrusion and the two lower edges positioned on both sides of the protrusion are respectively formed in close contact with the two lower edges extending below the protrusion. Allow close contact between the upper and lower edges of the notch. Therefore, when the protruding portion is inserted into the notch, the protruding portion cannot move in the lateral direction at all in the notch. Therefore, the column does not tilt with respect to the shelf board only by inserting the protrusion into the notch. In this state, if the contact portion between the support column and the shelf board is fixed with bolts, the assembly is completed. Therefore, the assembly is easy and the assembled shelf is difficult to twist.

Therefore, according to the present invention, it is possible to prevent the support column from being inclined with respect to the shelf board simply by inserting the protruding portion into the notch and then fixing it with a bolt. This is the greatest effect of the present invention.
In addition, when a support | pillar fixes a metal plate small piece and provided the protrusion part, since the protrusion part and a notch do not appear on the outer side of a shelf at all, the external appearance of a shelf is favorable.

It is a partially cutaway perspective view of still another support that can be used in the present invention. It is a partially cutaway perspective view of another metal shelf assembled by this invention.

  As already mentioned, FIG. 1 shows one embodiment of the present invention. In FIG. 1, the protruding portion 1 is formed by welding a small piece of metal plate to the inner side surface of the column B. The metal plate piece is formed by bending a right-angled quadrilateral metal plate at a right angle along a central line parallel to one side to make an L-shaped cross section. The metal plate pieces are welded in close contact with the inner side surfaces of the columns in accordance with the folds of the columns.

The protrusion 1 forms upper edges 11 and 111 bent in an L shape, and lower edges 13 and 131 depending on both sides of the upper edge. The upper edges 11 and 111 extend perpendicular to the longitudinal direction of the column, and the two descending edges 13 and 131 extend parallel to the longitudinal direction of the column.
The length L of the upper edge 11 or 111 of the protrusion perpendicular to the longitudinal direction of the support column can be 95 to 5% of the width W of the support column B. Among them, 80 to 10% is preferable. Particularly preferred is a range of 70 to 20%.

  On the other hand, the shelf board A is provided with a notch 2 on the side surface in contact with the column B. The notch 2 is made by making two cuts parallel to the shelf surface from the corner of one side wall 21, and further making a cut perpendicular to the shelf surface at the back of the cut, and cutting out a rectangular quadrilateral surrounded by the cut. It has been. The edge of the cut is a right quadrilateral edge. Thus, an upper edge 22, a vertical edge 24, and a lower edge 23 are formed in the notch 2.

  Similarly, the side wall 211 adjacent to the side wall 21 is cut from the corner to make a notch, and an upper edge 221, a vertical edge 241 and a lower edge 231 are formed. It is preferable that the notch attached to the side wall 21 and the notch attached to the side wall 211 are symmetrical. The two notches 2 formed in this way are combined to form a notch into which the protruding portion 1 can be inserted. The upper edges 22 and 221 of the notch 2 extend parallel to the shelf surface, and the vertical edges 24 and 241 located on both sides thereof extend perpendicular to the shelf surface.

  The length of the vertical edge of the notch 2, for example, the length M of the vertical edge 241 can be 95-5% of the height N of the side wall of the shelf A, but is preferably 80-20%, More preferred is 70 to 30%, and most preferred is in the range of 60 to 40%.

  In this case, the length of the upper edge 11 of the protrusion 1 is made equal to the length of the upper edge 22 of the notch 2, and the length of the upper edge 111 is made equal to the upper edge 221 of the notch 2. Then, the protrusion 1 can be inserted into the notch 2 just. Therefore, as described above, the side wall 21 is set along the inner surface of the support column B, the shelf A is advanced in the direction of the arrow E, and the upper side edge 22 of the side wall 21 is aligned with the upper edge 11 of the support column B. The shelf A is advanced in the direction of arrow E, and the protruding portion 1 is inserted into the notch 2. Then, the protruding portion 1 is completely fitted into the notch 2, and the shelf board A is locked to the column B. After that, by simply screwing the bolt C into the bolt hole 3, the shelf board A and the column B can be fixed to form a shelf.

In this case, the lower edge of the protrusion 1 may be in close contact with the lower edges 23 and 231 of the notch 2, but it is better not to be in close contact. This is because it is easier to insert the protruding portion into the notch if it is not in close contact.
Thus, the assembled shelf is fixed in a state in which the upper edges 22 and 221 of the notch 2 are in close contact with each other over substantially the entire length of the upper edges 11 and 111 of the projecting portion 1, so that the shelf board A falls. It is prevented. At the same time, since the descending edges 13 and 131 of the protrusion 1 are in close contact with the vertical edges 24 and 241 of the notch 2 for a considerable length, the protrusion 1 is fixed in a state where even the fine movement is not possible within the notch. Has been. Therefore, the column B cannot be tilted with respect to the shelf A. Thus, the shelf board A and the support column B are easily and firmly fixed by fitting the protruding portion 1 and the notch 2 so that the support column cannot be tilted with respect to the shelf board. The metal shelf according to the present invention is assembled in this way, and is difficult to twist.

The metal wagon according to the present invention is such that a caster is attached below each support column of the metal shelf assembled in this manner so that the shelf can be moved.
FIG. 2 shows a metal wagon according to the present invention. In FIG. 2, A is a shelf board formed by bending a metal plate into a right rectangular quadrilateral shallow box shape, B is a column made by bending the metal plate into an L-shaped section, and C Is a bolt which fixes the shelf A to the column B, and D is a caster attached below the column B. The metal wagon shown in FIG. 1 comes into contact with the corners of the four corners of the shelf A and the inner side surfaces of the four columns B, and each of the abutting portions is fixed by one bolt C. The shelf board A is placed between four columns B to form a metal shelf, and casters D are attached below each column B.

  In FIG. 3, the projecting portions are separately attached to the half portions of the column B connected to the L shape. Further, any of these protrusions is formed by extruding a part of the column. The upper edges 101 and 111 of these protrusions are located at the same height of the column B, and both extend perpendicular to the longitudinal direction of the column. Descent edges 13 and 131 are formed at the ends of the upper edges 101 and 111, both of which extend parallel to the longitudinal direction of the column. These are the same as those in FIG.

In the shelf A of FIG. 3, the front half of the side wall is folded inward to double the side wall, and the shelf is difficult to bend. Such a turn-back is missing in the portion that abuts on the support on the side of the shelf board.
In one side wall 21 of the shelf board A shown in FIG. 3, a notch 2 exactly the same as the side wall 21 in FIG. There, the upper edge 22 and the lower edge 23 extend parallel to the shelf surface, and the vertical edge 24 extends perpendicular to the shelf surface. The distance R from the end of the side wall 21 to the vertical edge 24 is equal to the distance P from the descending edge 13 of the protrusion to the folding line.

On the other side wall 211 of the shelf A, the end of the notch 2 is closed, and the notch 2 is formed into a right-angled quadrangular hole. The cutout may have such a shape. The upper edge 221 of the side wall 211 is located at the same height as the upper edge 22 of the side wall 21 and extends parallel to the shelf surface. The vertical edge 241 of the notch 2 extends perpendicularly to the shelf surface, and the distance S from the end of the side wall is made equal to the distance Q from the fold of the column B to the descending edge 131 of the protrusion.
In this case, the two notches 2 are sized such that the protruding portions 10 and 100 can be inserted therein.

  The shelf board A shown in FIG. 3 is similar to the shelf board A shown in FIG. 1. First, the side wall 21 is brought into contact with the inner side surface of the column B and is advanced in the direction of arrow E so that the side wall 21 is inside the notch 2. The protruding portion 10 of the column B is inserted into the column. Then, the upper edge 22 of the notch is supported by the upper edge 101 of the protruding portion 10 so that the shelf A is temporarily locked to the support column. Thereafter, when the shelf board A is further advanced along the arrow E, the protruding portion 100 of the support column B is inserted into the notch 2 where the side wall 211 is. At this time, since the distance P is equal to the distance R and the distance S is equal to the distance Q, the vertical edges 24 and 241 of the shelf A are respectively the descending edge 13 of the projecting portion 10 and the descending edge 131 of the projecting portion 100. The protrusions 10 and 100 are both held in the notch 2 without any backlash. As a result, the support column is maintained in a state where it cannot be tilted with respect to the shelf board.

In addition, the horizontal board 4 provided in the lower end of the support | pillar B in FIG. 3 is a board for attaching a caster. A hole 41 provided in the horizontal plate 4 is a bolt hole for mounting a caster.
In the present invention, the protrusion provided on the wand of the support can be provided by cutting up a part of the support as shown in FIGS. 4 and 5 in addition to the means shown in FIGS. In FIG. 4, a U-shaped cut is horizontally placed in each bent half of the column B, and the protrusions 10 and 100 are formed by slightly projecting the inside of the cut, thereby forming the upper edge 11 and 111 and descending edges 13 and 131 are provided.

In FIG. 5, two U-shaped cuts having a small depth are placed in each half of the column B in parallel with the longitudinal direction of the column, and the inside of the cut is erected almost vertically and orthogonal to each half. The upper edge 11 and the lowering edge 10 as well as the upper edge 111 and the lowering edge 100 are formed. Such a projection may be used.
4 and 5 is provided on the support column B, the notch provided on the ledge of the shelf can be shaped as shown in FIGS. 1 and 3, but FIG. As shown in FIG. 5, the upper edge side 22 and the vertical edge 24 that are in close contact with the upper edge 11 and the lowering edge 10 can be formed. Further, the shelf A can be provided with a notch in which the upper edge 221 and the vertical edge 241 that are in close contact with the upper edge 111 and the descending edge 100 of the protruding portion are separated.

  In the case where the protrusion provided on the support B has a hexagonal shape, as shown in FIG. 6, a substantially regular hexagonal plate is bent at a right angle along the central axis extending in the longitudinal direction, and the cross section is symmetrical. In addition, it is preferable that a shape extended in the direction of the central axis is welded to the inner surface of the column with the central axis aligned with the folding line of the column. In this case, as shown in FIG. 6, it is preferable to weld the hexagonal upper edges 11 and 111 so as to be perpendicular to the longitudinal direction of the support column, but as shown in FIG. May extend obliquely symmetrically with respect to the central axis, and an edge adjacent thereto may be parallel to the longitudinal direction of the column.

  When the protrusion is configured as shown in FIG. 6, the descending edge of the protrusion extending in the longitudinal direction of the support column is bent in a “<” shape. In this case, the notch 2 provided in the shelf board A just receives the protrusion, the upper edge of the notch 2 is in close contact with the upper edge of the protrusion, and the vertical edge extending in the direction perpendicular to the shelf surface of the notch 2 is: It is bent in the shape of a “<” and is in close contact with the descending edge of the protrusion.

  In the case where the protruding portion is hexagonal, the column B as shown in FIG. 8 can be used as the column B instead of the column B shown in FIG. In FIG. 8, the hexagonal protrusions are made by making a cut in four sides of the U-shape with the central part bent at each half of the column and slightly extruding the inside of the cut.

  When the protrusion provided on the support B is octagonal, as shown in FIG. 9, the upper edges 11 and 111 of the protrusion are extended perpendicular to the longitudinal direction of the support B, and the oblique edge 15 following the upper edge is extended. And 151 are shortened, the descending edges 13 and 131 that follow are lengthened and extend parallel to the longitudinal direction of the column, and the subsequent oblique edges 16 and 161 are the same length as the oblique edges 15 and 151. It is preferable that the lower edge has the same length as the upper edge and extends perpendicular to the longitudinal direction of the column.

  As shown in FIG. 9, it is preferable that the protruding portion has a vertically symmetrical shape. Since the shelf board A can be installed upside down if it is vertically symmetrical, the shelf board A can be used as a square dish with side walls, and at the same time, the same shelf board can be used as a top board with the side walls facing downward. Can also be used conveniently.

  Moreover, as a polygon which a support | pillar attaches to a trap, it is preferable that the edge extended in parallel with the longitudinal direction of the support | pillar B is longer than the edge extended perpendicularly | vertically to the longitudinal direction of the support | pillar B. That is, with respect to FIG. 1, it is preferable that the lengths of the descending edges 13 and 131 are larger than the lengths of the upper edges 11 and 111. In this way, when the protruding portion is inserted into the notch, it becomes easy to reduce rattling of the protruding portion in the notch, and therefore, it is possible to reliably prevent the column from tilting with respect to the shelf board. .

  The part where the shelf board A is fixed to the column B with the bolts C can be as shown in FIG. 10, for example, in addition to those shown in FIGS. In FIG. 10, the end of the side wall of the shelf board A is folded inward over the entire length of the side wall so that the side wall is doubled, and the folded back 25 extends to the corner of the shelf board.

  Originally, as shown in FIGS. 1 and 3, the shelf board A and the support column B are provided with bolt holes 3, and the bolts are passed through the nuts and fixed with nuts. However, in FIG. 10, since the folding | returning 25 has covered the bolt hole 3, the nut cannot be attached. Therefore, a nut hole 31 for passing a nut is formed in the turnback 25. The nut hole 31 does not only pass through the nut F but also needs to be rotated or fixed, so that the nut hole 31 is large enough.

  Leaving the large nut hole 31 as it is not only looks bad, but it may also impair safety. Therefore, the cap 5 is fitted in the nut hole 31 so as to close the hole. The cap 5 has a structure in which a disk-shaped head and a cylindrical leg are integrated. The diameter of the cylindrical leg is slightly reduced, and the cap is split into two along the cylindrical axis. Yes. The cap 5 is made by integrally molding with a synthetic resin having elasticity in such a structure, for example, polypropylene. Therefore, the cap 5 is locked to the nut hole 31 by the elasticity of the cylindrical leg. Therefore, attachment and removal of the cap 5 are easy.

  According to this invention, it is possible to easily assemble a solid shelf in which the protruding portion provided on the support column is fitted into the notch provided on the shelf plate, and the column is not tilted with respect to the shelf plate simply by being coupled with the bolt. Therefore, the present invention has great practical value. In addition, since the caster can be attached below each column of the shelf thus assembled to form a solid wagon, the present invention is further of practical value.
