  Next, an assembly shelf according to an embodiment of the present invention will be described with reference to FIGS. The assembly shelf 10 is fitted into the four support columns 2 formed with locking grooves or locking holes at regular or irregular intervals in the longitudinal direction, the coupling member 1 attached to the support column 2, and the coupling member 1. And a shelf member 31 having a concave engaging portion 3. In order to fix one shelf member 31 to the column 2, one shelf member 31, four columns 2, and four coupling members 1 are required. The assembly shelf 10 having three upper and lower shelves in FIG. 1 requires three shelf members 31, four support columns 1, and 12 sets of coupling members 1. Twelve sets of coupling members 1 are 12 members, that is, 24 members. In the present invention, the front means a direction orthogonal to the direction in which the concave inner peripheral surface of the concave engagement portion 3 faces.

  The coupling member 1 is fitted to the support column 2, and one shelf member 31 is located in a ½ region in the radial direction of the coupling member 1 in a front view (in the region indicated by reference symbol X / 2 in FIG. X is supported by the length of the coupling member 1 in the left-right direction (see FIGS. 1 and 17). In order to support one shelf member 31 within a ½ region in the radial direction of the coupling member 1 in front view, the position change of the intermediate shelf member in the assembly shelf having a plurality of upper and lower stages can be performed without changing the other shelf members. The intermediate shelf member can be hollowed out. In addition, the other shelf members can be assembled in the horizontal direction without changing the existing assembly shelf.

  As shown in FIGS. 3 and 5, the coupling member 1 includes two members 1 a and 1 b that are fitted to each other so as to embrace the column 2 from both sides, and each of the two members 1 a and 1 b is directed downward. The first taper 16a (16b) is formed in a shape that gradually increases in diameter according to the above, and the second taper 17a (17b) is formed in a shape that gradually decreases in the downward direction, and the coupling material 1 is fitted into the column 2 At this time, the first taper 16a of one member 1a and the second taper 17b of the other member are arranged in a ½ region in the radial direction of the coupling member 1 (reference numeral X / 2 in FIG. 17) in a front view. Is done. That is, the radial direction of the coupling member 1 in front view refers to the radial direction extending in the left-right direction in front view. Further, when the coupling member 1 is fitted into the support column 2, the first taper 16b of the other member 1b and the second taper 17a of the one member are the other one in the radial direction of the coupling member 1 in a front view. / 2 It is arranged in the area. As described above, since the two tapers for coupling the two members of the one member 1a and the other member 1b are arranged in the ½ region in the radial direction of the coupling member 1 in a front view, the hollowing operation is performed. It becomes possible. In addition, the code | symbol a is attached | subjected to one member and b is attached | subjected to the other member, respectively.

  The gradual diameter expansion of the first taper 16a (16b) is based on the axis of the support column 2 when the coupling member 1 is assembled to the support column 2. Therefore, the gradual diameter expansion of the first taper 16a (16b) refers to an inclination that is away from the axis of the support column 2 downward. Further, the gradual reduction in the second taper 17a (17b) is based on the front view when the coupling member 1 is assembled to the support 2 and based on the axis of the support 2. Therefore, as shown in FIG. 10, the gradual reduction in the second taper 17a (17b) refers to an inclination that approaches the axis of the support column 2 downward in a front view (simply, an inclination in the left-right direction in the front view). Say.) The front side refers to the side in which the connecting direction of the shelf members is the left-right direction, that is, the side F in FIG. In addition, although one side of the connection direction length of a shelf member becomes a longitudinal direction normally, it does not necessarily become a longitudinal direction. Moreover, the corner | angular part of the wall part in which the 2nd taper 17a (17b) is formed is an acute angle from a planar viewpoint (refer FIG. 8). Thereby, the collar part 32 of the concave engaging part 3 does not come off outside.

  The two members forming the coupling member 1, that is, one member 1a and the other member 1b may have the same shape and the same dimensions. In this example, one member 1a and the other member 1b have the same shape and the same dimensions, and if one member 1a is inverted 180 degrees on a plane, it becomes the other member 1b. When the one member 1a and the other member 1b have the same shape and the same size, only one mold is required, and the manufacturing cost is reduced. In the following description, the description of one member 1a is the description of the other member 1b.

  Each of the two members 1a and 1b in the coupling member 1 includes a main body portion 11a (11b) having an inner peripheral surface 142 (143) corresponding to the side surface shape of the support column 2 and the support column 2 from both sides of the main body portion 11a (11b). These arm portions 12a and 13a (12b and 13b) extend in the radial direction (inward direction). That is, in this example, as shown in FIGS. 4 to 11, one member 1 a includes a main body portion 11 a having a concave inner peripheral surface 142 corresponding to the peripheral surface shape of the support column 2, and one of the main body portions 11 a. Two arm portions 12a that are separated from each other in the vertical direction extending in the radial direction of the support column 2 from the side (opposite side in front view) and the central portion in the vertical direction on the other side (front side in front view) of the main body portion 11a. The other member 1b includes a main body portion 11b having a concave inner peripheral surface 143 corresponding to the peripheral surface shape of the support post 2, and a main body portion 11b. One arm portion 13b extending in the radial direction of the column 2 from the vertical center of one side (opposite side in front view) of the column 2 and the column 2 from the other side (front side in front view) of the main body 11b The two arms that are spaced apart from each other in the vertical direction extending in the radial direction Consisting of a 2b.

  When the coupling member 1 is fitted into the support column 2, one arm portion 13b of the other member 1b fits in the space between the two arm portions 12a of the one member 1a, and between the two arm portions 12b of the other member 1b. One arm portion 13a of one member 1a is fitted into the space. That is, when the coupling member 1 is fitted into the support column 2 in one arm of both arms, the arm of one member and the arm of the other member are alternately arranged.

  The main body 11a (11b) has a concave plate shape having a predetermined height and a predetermined width, and has a first taper 16a (16b) having a shape in which the outer peripheral surface of the predetermined width and the predetermined height is expanded in the downward direction. It has become. The predetermined width dimension is not particularly limited, but is approximately the diameter of the support column 2 in a side view. Thereby, intensity | strength can be hold | maintained and the fitting intensity | strength to the support | pillar 2 can be raised. If the taper of the first taper 16a (16b) is approximately 2 to 3 degrees, sufficient tightening strength can be provided.

  Further, the inner peripheral surface 142 (143) of the main body portion 11a (11b) is further provided with a protrusion 14a (14b) or a protrusion that is locked to the support column 2. The protrusion 14a (14b) is engaged with the annular or partial annular engagement groove 22 of the support column 2, and is formed on a part or all of the inner circumferential surface 142 (143) in the width direction. Article. When the protrusion 14a (14b) and the locking groove 22 are locked, the movement in the vertical direction can be restricted. Moreover, in the case of a protrusion, it will engage with the locking hole of the support | pillar 2 (not shown). The locking hole is a bottomed non-through hole or a through hole.

  Both arms 12a, 13a (12b, 13b) are for forming the second taper 17a (17b). The arm lengths of both arm portions 12a and 13a (12b and 13b) are formed such that when the coupling member 1 is fitted into the support column 2, the distal end portion further extends from the center of the support column 2 in front view. The second taper 17a (17b) can be formed in the other half region in the radial direction of the coupling member 1.

  As shown in FIG. 5, the taper shape of the second taper 17a (17b) in one member 1a (1b) is a rectangular plane having a predetermined length and a predetermined width, and appears in a front view. is there. That is, as shown in FIG. 8, the second taper 17 a (17 b) is formed on the side opposite to the main body that can be obtained by hollowing out the central portion in the length direction of a plate-like object having a predetermined thickness as an arm portion. Say the wall. If the taper of the second taper 17a (17b) is approximately 2 to 3 degrees, sufficient tightening strength can be provided.

  In addition, the wall 18a (18b) formed on the main body 11a (11b) side, which is formed by hollowing out the central portion in the length direction of the plate-like object having a predetermined thickness, attaches the coupling member 1 to the support column 2. In this case, the other member is formed so as to be positioned closer to the main body than the second taper 17b. Thus, when the coupling member 1 is assembled to the support column 2 and the concave engaging portion 3 of the shelf member 31 is fitted, only the first taper 16a of one member 1a and the second taper 17b of the other member 1b are concavely engaged. The wall portion 18a (18b) does not become a hindrance to assembling.

  As shown in FIG. 10, when the coupling member 1 is assembled to the support 2, the taper that appears on the right side of the axis of the support 2 in front view is the first taper 16 a that expands downward, The first taper 16a is a second taper 17b, 17b having an inversely inclined shape. The second tapers 17b and 17b that appear in the front view are formed on the upper and lower arms that are separated from each other, and are thus separated, but the taper has a continuous shape. On the other hand, the second taper 17b shown in the rear view is one arm at the center. The wall portion 18a that appears between the second tapers 17b and 17b in a front view is formed on one member, and is not continuous with the second tapers 17b and 17b but is a step. The level difference between the second tapers 17b and 17b and the wall portion 18a is referred to as a tension allowance m (see FIG. 10), and the two members 1a and 1b can hold the column 2 firmly. When the tension allowance m is zero, the effect of strongly hugging is drastically reduced.

  Further, in both arm portions 12a and 13a (12b and 13b), the concave surface 15a (15b) located between the second taper 17a and 17a (17b and 17b) and the wall portion 18a (18b) gradually expands downward. It is the taper shape (5th taper) formed in this shape. The fifth taper corresponds to the sixth taper of the concave engaging portion 3 of the shelf member 31, and the fitting of the concave engaging portion 3 to the coupling member 1 allows the coupling member 1 to be fitted to the column 2. The combined strength is increased. If the taper of the fifth taper 15a (15b) is approximately 2 to 3 degrees, sufficient tightening strength can be provided.

  The coupling member 1 is made from a metal, a resin, or a composite thereof. Among these, resin-made ones are preferable in that no metal sound is generated during assembly and the assembly is easy. As the resin, engineering plastics such as polyacetal resin, polyamide resin, acrylonitrile-butadiene-styrene copolymer synthetic resin (ABS resin), epoxy resin, phenol resin, and polycarbonate resin can be used. These synthetic resins are excellent in impact resistance, wear resistance, and chemical resistance. The resin may further contain reinforcing fibers such as glass fibers and carbon fibers.

  As the support | pillar 2, what formed the cyclic | annular or partial cyclic | annular locking groove in the longitudinal direction at the regular or irregular space | interval can be used. The cross-sectional shape of the support column 2 is not particularly limited, and examples include a circular cross section, an elliptical cross section, a square cross section, a rhombic cross section, an X shape, and an H shape. The partial annular groove may be a groove that is cut linearly with respect to the outer peripheral surface and has a large groove depth at the center of the groove and becomes shallower toward the end of the groove.

In the shelf member 31 used in the assembly shelf 10, at least one of the recessed engagement portions 3 is formed at a position other than the four corners of the shelf member 31. The four corners of the shelf member 31 refer to the ends (side portions) where the concave engaging portions 3 are formed. When the shelf member 31 is rectangular in plan view, the rectangular end portions (side portions) or Say neighborhood. Concave engaging portion 3 of the present example is formed at a position entering the inner L ₂ minutes from the end (see FIG. 2). By installing the concave engagement portion 3 on the inner side, the support column 2 is less likely to stay on the eye and the feeling of pressure is lost. Moreover, since there is a small space shelf surface on the outside of the support column 2, display different from the conventional one is possible. The shelf body portion of the shelf member 31 may be either a board shape or a mesh shape. L ₂ length is applied to at least one strut is preferable that entered the inside of at least 5cm or more from the end, a further _{(L 1/4) ± (} L 1/8) degrees is particularly preferred .

  The concave engaging portion 3 includes a third taper 33 that contacts the first taper 16a (16b) of one member 1a of the coupling member 1 and second tapers 17b and 17b of the other member 1b of the coupling member 1. And a sixth taper 36 that contacts a fifth taper 15a (15b) formed on both arms 12a (12b) and 13a (13b) of the coupling member 1. The assembly shelf 10 is formed by fitting the concave engagement portion 3 into the coupling member 1, and the shelf member 31 is disposed between the axial centers of the two columns 2 and 2 in a front view. The fifth taper 15a (15b) of the coupling member 1 and the sixth taper 36 of the concave engaging portion 3 are optional components.

As shown in FIGS. 13 to 15, the concave engagement portion 3 of the shelf member 31 includes an engagement main body portion 35 having an inner peripheral surface corresponding to the left and right side surface shape of the coupling member 1, and the engagement main body portion 35. A third taper 322 is formed on the inner peripheral surface (inner wall surface) 33 on the back side of the hollow portion 311 and gradually expands downwardly. A fourth taper 321 is formed on the surface 32 of the portion 34 on the third taper side. That is, as shown in FIGS. 13 and 15, the fourth taper 321 appears in a front view (reference numeral Z ₂ -Z _{2 in} FIG. 13), and the second taper 17 a (17 b) of the coupling member 1. ). Further, the third taper 322 has a shape corresponding to the shape of the first taper 16 a (16 b) of the coupling member 1, and in this example, has a concave shape that increases in diameter downward.

  Further, the inner side surface 36 of the flange portion 34 has a taper (sixth taper) gradually expanding downward. The sixth taper 36 corresponds to the fifth taper 15 a (15 b) of the coupling member 1. By fitting the concave engagement portion 3 into the coupling member 1, the sixth taper is changed to that of the coupling member 1. Since both arm parts 12a and 13a (12b and 13b) are pushed strongly to the support 2 side, the fitting strength of the coupling member 1 to the support 2 is increased. If the taper of the sixth taper 36 is approximately 2 to 3 degrees, sufficient tightening strength can be provided.

  Further, the corner of the flange portion 34 on the third taper side is an acute angle in plan view. Thereby, the wall part (2nd taper 17a (17b)) formed in the same acute angle engages, and the engagement of the concave engagement part 3 does not come off outside.

  Next, an example of a method for fixing the shelf member 31 to the column 2 will be described below. First, the lowermost shelf member 31 b is fixed to the support column 2 via the coupling member 1. That is, the coupling member 1 is attached to a predetermined position below the column 2 in the height direction. The coupling member 1 is fitted so that the two members face each other and the support column 2 is held from both sides. At this time, the locking groove 22 of the support column 2 and the protrusion 14a (14b) of the coupling member 1 are matched. As a result, the locking groove 22 of the support column 2 and the protrusion 14a (14b) of the coupling member 1 are locked and restrict the movement in the vertical direction. The coupling member 1 is attached to the four struts 2. Next, the concave engaging portion 3 of the shelf member 31b is pushed into the coupling member 1 from above to below (FIG. 17A). As a result, the third taper 322 of the shelf member 31 abuts against the first taper 16a of one member 1a of the coupling member 1 and presses the one member 1a in the direction of the column 2 (FIG. 17A). Direction), the fourth taper 321 of the shelf member 31 is in contact with the second taper 17b of the other member 1b of the coupling member 1, and presses the other member 1b in the direction of one member side (FIG. 17A). In the direction of reference B), the support column 2 is hugged by the two members of the coupling member 1 (FIG. 17B). Thus, the shelf member 31 and the support column 2 are not in contact with each other, and the shelf member 31 is supported by the coupling member 1, and the concave engagement portion 3 of the shelf member 31 is positioned below the coupling member 1. By pushing to the side, the coupling member 1 is strongly fixed to the support column 2. Next, the intermediate shelf member 31a and the uppermost shelf member 31 are attached, and either may be attached first. That is, the intermediate shelf member 31a and the uppermost shelf member 31 may be attached first, or the uppermost shelf member 31 and the intermediate shelf member 31a may be attached first. In the conventional assembly shelf, the intermediate shelf member 31a cannot be attached last, but in the assembly shelf of the present invention, the intermediate shelf member 31a can be attached last. It becomes easy.

Assuming that one assembly shelf 10 as shown in FIG. 1 is provided (usually upper and lower stages), the shelf member 31 is disposed between the shafts of the two columns 2 and 2 in a front view (see FIGS. 1 and 17). ). That is, as shown in FIG. 26, the length (l ₂ ) of one side in the front view of the shelf member 31 is the length between the axis Y of the support column 2 on one side (left side) and the axis Y on the other side (right side). Is equal to or slightly smaller than (l ₁ ). That is, one shelf member 31 is supported in a ½ region in the radial direction of the coupling member 1 in a front view. As shown in FIG. 26, when the length (l ₂ ) of one side in the front view of the shelf member 31 is slightly smaller than the length (l ₁ ) between the shafts of the two columns 2 and 2, the assembly is performed. When connecting the shelves 10, the end portions (side portions) of the two shelf members 31 do not come into contact with each other, and assembly is facilitated. The gap between the end portions of the two shelf members 31 assembled (twice between the axis of one assembly shelf column 2 and the end surface of the shelf member 31) (reference numeral n in FIG. 27) is preferably within 5 mm. Is preferably within 2 mm from the standpoint that the small items placed on the shelf member 31 can be prevented from falling. The edge part of the shelf member 31 is an edge part of the concave engaging part 3 in this example. Thus, the both ends of the shelf member 31 are not located outside the axis of the two support columns 2 and 2 when viewed from the front. In addition, the axial center Y says the center of the support | pillar 2 extended in the perpendicular direction in front view.

  The shelf member 31 is supported in a half region in the radial direction of the coupling member 1 in a front view. In this way, by using half of the support column 2 (half of the coupling member 1), when two of the assembly shelves 10 are connected in the longitudinal direction, one support column 2 is connected to the left and right shelf members 31, 31. Can be shared when fixing (FIGS. 16 and 19).

  In the shelf member 31 used in the assembly shelf 10, the number of support columns 2 is not limited to four, and may be two, three, or five or more, for example. In this case, at least the number of the supporting columns 2 to be used is formed on the shelf member 31 in the concave engaging portion 3. When there are two, three, or five or more struts 2, the formation position of the concave engagement portion 3 in the shelf member 31 is determined at an appropriate position in consideration of the purpose of use, installation stability, design, and the like. When there are two or three columns 2, it is possible to produce an elegant shelf that is not present. Moreover, when the number of the support | pillars 2 is five or more, installation strength and installation stability can be improved.

  Next, the coupled assembly shelf will be described with reference to FIG. That is, in the assembly shelf 10, the third taper 322 that contacts the first taper 16 b of the other member 1 b of the coupling member 1 and the fourth taper 321 that contacts the second taper 17 a of one member 1 a of the coupling member. This is obtained by fitting another shelf member having the concave engagement portion 3 having the other engagement member 3 into the other region of the coupling member 1 of the assembly shelf 10. That is, the connected assembly shelf 20 is another shelf member of the same shape that is connected in the longitudinal direction of the assembly shelf 10 in the other half region in the radial direction (longitudinal direction) of the coupling member 1 in the front view. The assembly shelf 20 can be formed by fitting the two concave engaging portions 3 and connecting the two shelf members 31, 31 through the single column 2. That is, as shown in FIG. 19, the assembly shelf 20 has two assembly shelves by providing shelf members 31 on both sides of one column 1. The assembly shelf 20 is different from the assembly shelf 10 in the fixed portion of the intermediate column 2. That is, as shown in FIGS. 1 and 19, the shelf member 3 to be newly connected is attached to the other half region portion in the radial direction of the coupling member 1 that is not used in the assembly shelf 10. The shelf member 31 to be used and the mounting method thereof are the same as in the case of the assembly shelf 10.

  In the assembly shelf 10 and the assembly shelf 20, for example, a case where it is desired to remove the intermediate shelf member 31a or a case where it is desired to change the installation position (a hollowing operation) will be described with reference to FIGS. The hollow of the intermediate shelf member 31a in FIG. 1 slightly lifts the intermediate member 31a upward. At that time, there is no obstacle in the upper space S of the intermediate member 31a, and there is a sufficient gap between the support column 2 and the concave engaging portion 3 of the shelf member 31 in the portion where the coupling member 1 does not exist. When slightly lifted, the intermediate shelf member 31a is tilted so as to be inclined downward or upward in the longitudinal direction (see FIG. 18). This tilted position is a position where the horizontal dimension of the tilted intermediate shelf member 31a is smaller than the gap between the two columns 2 and 2 of the assembly shelf 10. If the intermediate shelf member 31a is pulled out from the state in which the intermediate shelf member 31a is inclined, the intermediate shelf member 31a can be removed. After that, if the coupling member 1 is removed or attached by changing the position and the intermediate shelf member 31a is reinstalled, the installation position of the intermediate shelf member 31a can be changed.

  In order to reinstall the intermediate shelf member 31a, an operation method opposite to the above removal method may be used. In this way, the assembly shelf 10 and the assembly shelf 20 can be easily subjected to a hollowing operation.
