  The assembly shelf 10 includes a column 1, a pair of coupling members 2, and a shelf member 3. In order to fix one shelf member 3 to the column 1, one shelf member 3, four columns 1, and four sets of coupling members are required. The assembly shelf 10 having three upper and lower shelves in FIG. 1 requires three shelf members 3, four support columns 1, and 12 sets of coupling members. Twelve sets of coupling members mean that there are 12 pairs of coupling members, and the number of members of the coupling members is 24.

  In the assembly shelf 10, the column 1 is symmetric about a column axis (virtual vertical axis at the center of the coupling unit), which includes two main columns 11 (11 a, 11 b) and a coupling unit 12 that couples the main column 11. Shape. That is, the support column 1 is obtained by integrating the two main support columns 11 (11a, 11b) and the connecting portion 12. The symmetrical shape means line symmetry in the longitudinal direction of the shelf member in the use state with the support shaft as the center, and line symmetry in the short direction of the shelf member. The planar shape of the main column 11 is not particularly limited, but in this example, it is a substantially flat, substantially pentagonal shape, and the corners of the substantially pentagonal shape are rounded. The length (longitudinal direction) in the vertical direction of the main column 11 is appropriately determined depending on the number of shelves. Such a main column 11 gives strength to the column 1 and facilitates the engagement of the coupling member 2. Although the main support | pillar 11 may be a substance or a hollow body, it is preferable that it is a hollow body at the point which can provide lightweight and high intensity | strength. When the main support column is a hollow body, it is preferable to cover the open end opening with a cap.

  The assembly shelf 10 is formed with a plurality of lateral grooves (engagement recesses) 13 at predetermined regular pitches in the longitudinal direction (up and down direction) on both side surfaces 111a and 111b of the main column 11 (11a and 11b). Since the lateral groove (engagement recess) 13 is formed on a rounded side surface, the depth of the central portion and the depth of both end portions are different, the depth of both end portions is zero, and is continuous with the shape of the main column 11. In the lateral groove 13, if the central portion has a depth, the protrusions 25a and 25b can be reliably engaged and are sufficient for supporting as a shelf. The pitch interval in the longitudinal direction of the lateral grooves (engagement recesses) 13 is appropriately determined depending on the length of the main column 11 or the purpose of use. Further, the depth of the lateral groove (engagement recess) 13 is appropriately determined depending on the thickness or supporting weight of the main column 11.

  The lateral grooves (engaging recesses) 13 on both side surfaces 111a and 111b, that is, the lateral groove 13 that appears in front of FIG. 2 and the lateral groove 13 that does not appear in FIG. It extends parallel to each other in the horizontal direction. In FIG. 2, the lateral groove 13 of the main column 11 a and the lateral groove 13 of the main column 11 b are in the same position in a side view. The lateral groove 13 enables the coupling member 2 to be attached and serves as a guide for the installation position (height) of the shelf member.

  The shape of the connecting portion 12 is a plate-like long body having a predetermined width and a predetermined thickness. The thickness of the connecting portion 12 is determined as appropriate so that the strength of the support column 1 can be imparted. Further, the width of the connecting portion 12 (the length in the YY direction in FIG. 2) is appropriately determined depending on the thickness of the inner arm portions 23a and 23b forming the first engaging portions 22a and 22b of the coupling member 2. .

  Assuming that the assembly shelf 10 as shown in FIG. 1 is one unit (usually upper and lower stages), in one support column 1 used in one assembly shelf, the pair of coupling members 2 and 2 and the shelf member 3 are provided as support columns. 1 in the short direction (the YY direction in FIG. 2 and the longitudinal direction in plan view), that is, a half of the Y-direction of one main column 11a and the connecting portion 12 (see FIG. 2). 2 in the X region). In this way, when two of the assembly shelves 10 are connected in the Y-Y direction by using half of the support columns 1, one support column 1 is shared when the left and right shelf members 3 and 3 are fixed. (FIGS. 4 and 6).

  The pair of coupling members 2 a and 2 b have a first engagement portion that engages with the column 1 and a second engagement portion that engages with the shelf member 3, and has a half region in the short direction of the column 1. The column 1 is attached so as to be clamped from both sides. The pair of coupling members 2a and 2b are symmetrical to each other, and only one of the coupling members will be described. The one coupling member 2a is substantially U-shaped in plan view having a predetermined height (length in the vertical direction), and has a concave portion 22a having a shape corresponding to one side surface shape 16 of the one main support column 11a. And a protrusion 25a that fits in the lateral groove 13 formed on the inner surface of the recess 22a, and an inner arm 23a that is a part of the component forming the recess 22a and has a length until it comes into contact with the connecting portion 12. . That is, the first engaging portions are the concave portion 22a that contacts the side surface of the main column 11a, the protruding portion 25a, and the inner arm portion 23a. The arm-like portions 23a and 23b are in contact with or close to the connecting portion 12, but the contact or close portions are arranged in a half region in the short direction of the support column 1 of the connecting portion 12 (in the direction orthogonal to the support shaft). It is installed.

  The protrusion 25a is formed integrally with the coupling member 2a, and engages with the lateral groove 13 of the main column 11 to control the engagement between the column 1 and the coupling member 2. The shape of the protrusion 25a is a rod-like shape that has a rectangular cross section and extends in the YY direction.

  Further, a plate-like object (protruding object) (second engaging portion) 24a is formed on the outer surface of the back plate 21a and slightly below the center. The second engagement portion 24a is symmetrical with respect to a vertical axis passing through the center, and has inclined side surfaces 242 and 242 that gradually expand downward and an inclined back surface 241 that gradually expands downward. Note that the inclination of the inclined back surface 241 is gentler than that of the inclined side surface 242. Further, the lower end surface of the second engaging portion 24a and the lower end surface of the coupling member 2a are flush with each other.

  Further, a plate-like object (protruding object) (second engaging portion) 24b (not shown) is formed on the outer surface of the back plate 21b, like the one coupling member 2a. The shape of the second engagement portion 24b is the same as that of the second engagement portion 24a of one coupling member 2a. Note that the height (vertical length) of the pair of coupling members 2 a and 2 b is substantially the same as the height (thickness) of the shelf member 3.

  In order to attach the pair of coupling members 2a and 2b to the support column 1, first, the coupling members 2a and 2b are provided with projections 24a and 24a in the two lateral grooves 13 at the position where the shelf member 3 is to be installed. Further, the concave portions 22a of the one coupling member 2a are applied to one side surface 16 of the main column 11a. Next, the other coupling member 2b is similarly assembled to the main support column 11b (FIG. 3). Since the assembly of the pair of coupling members 2a and 2b and the support column 1 has almost no gap between the members, it is as if the shape of a part of the support column 1 is. That is, the assembly of the pair of coupling members 2a and 2b and the support column 1 is a box-shaped body formed in a half region in the short direction of the support column 1, and a plate-like object (protruding shape) is formed on both sides of the box-shaped body. Thing) 24a and 24b are attached.

  The shelf member 3 is configured such that third engagement portions 31 that engage with plate-like objects (projections) 24a and 24b (second engagement parts) are formed at substantially four corners. In this example, the four corners are ends of the shelf member 3 in the short direction. By setting the four corners to such positions, the installation area formed by the four columns can be increased, and the installation of the assembly shelf 10 is stabilized. The shelf main body portion of the shelf member may be either a board shape or a mesh shape, but it is preferable that the shelf shape is easy to form the third engagement portion 31.

  The third engaging portion 31 of the shelf member 3 is formed by hollowing out a portion 311 corresponding to the volume for storing the box-shaped body formed by the pair of coupling members 2a and 2b and the support column 1, and the plate-like objects 24a and 24b. A portion 34 corresponding to the volume in which the shape is accommodated is formed on both sides of the portion 311. That is, the inclined surface 33 at the front end of the left and right small spaces 34 of the third engaging portion 31 is an inclined surface that gradually increases as it goes downward, and the side surface 341 of the small space 34 is an inclination that gradually increases as it goes downward. Surface. When the third engagement portion 31 of the shelf member 3 is engaged with the second engagement portions 24a and 24b, the respective taper portions of the second engagement portion and the third engagement portion are fitted to make the both strong. In addition to being fixed, the top surface of the concave portion forming the small space 34 comes into contact with the upper surface of the plate-like object 24a, so that the downward pushing is stopped and the vertical position is determined, and the pair of coupling members 2a, 2b Is not disconnected (FIG. 4).

  In the assembly shelf 10, another shelf member connected in the longitudinal direction of the assembly shelf and the other shelf member of the same shape that fixes the other shelf member in the other half region in the short direction of the column 1. The coupling shelf 20 is fitted, and the two shelf members 3 and 3 are connected to each other through one support column 1, whereby the assembly shelf 20 can be formed. That is, as shown in FIG. 6, the assembly shelf 20 is configured as two assembly shelves by providing the shelf members 3 on both sides of one column 1. The assembly shelf 20 is different from the assembly shelf 10 in a fixed portion of the intermediate support column 1. That is, as shown in FIG. 4, the shelf member 3 and the pair of coupling members 2a and 2b that are newly connected to the other half region portion in the short direction of the column 1 that is not used in the assembly shelf 10 are used. Is attached. The shelf member 3 and the pair of coupling members 2a, 2b to be used and the mounting method are the same as those of the assembly shelf 10. The assembly shelf 10 may be an assembly shelf that is connected in triplicate or more in a similar manner.

  In the assembly shelf 10 and the assembly shelf 20, for example, a case where it is desired to remove the intermediate shelf member 3 b or a case where it is desired to change the installation position (a hollowing operation) will be described with reference to FIGS. 1, 7, and 8. The hollowing of the intermediate shelf member 3b in FIG. 7 slightly lifts the intermediate member 3b upward. At that time, there is no obstacle in the upper space X of the intermediate member 3b, and there is a sufficient gap between the support column 1 and the third engaging portion 31 of the shelf member 3 in the portion where the coupling members 2a and 2b are not present. Become. When slightly lifted, the intermediate shelf member 3b is inclined so as to be inclined downward or upward in the longitudinal direction (see FIG. 7). This tilted position is a position where the horizontal dimension of the tilted intermediate shelf member 3b is smaller than the gap between the two columns 1 and 1 of the assembly shelf 10. If the intermediate shelf member 3b is pulled out from the state in which the intermediate shelf member 3b is inclined, the intermediate shelf member 3b can be removed. After that, the pair of coupling members 2a and 2b may be removed or the positions may be changed. In order to reinstall the intermediate shelf member 3b, an operation method opposite to the above removal method may be used. The state after the re-installation of the intermediate shelf member 3b is shown in FIG. In this way, the assembly shelf 10 and the assembly shelf 20 can be easily subjected to a hollowing operation.

  The assembly shelf of the present invention is not limited to the above embodiment, and various modifications can be adopted. For example, as the cross-sectional shape of the main column 11, a circular cross-sectional shape, an elliptical cross-sectional shape, a triangular cross-sectional shape, and the like can be cited in addition to the above-described flat, substantially pentagonal shape. Further, instead of engaging the lateral groove (engagement recess) 13 of the main column 11 and the projection (engagement projection) 24 of the coupling member 2, the projection (engagement projection) 24 is coupled to the main column 11. An engagement form in which the lateral groove 13 is formed in the member 2 may be employed. In addition, the shapes of the engagement recesses and the engagement protrusions are not limited to the above-described lateral grooves and rod-shaped members having a rectangular cross section, but include engagement forms of circular grooves and circular protrusions, engagement forms of elliptic grooves and elliptic protrusions, and the like. Various engagement forms can be taken.

  The assembly shelf of the present invention can be used as a display shelf that can be easily assembled and disassembled in offices, homes, warehouses, stores, etc., and in stores.
