[0006] [Problems to be solved by the invention]

[0007] In this combination frame, since the pair of protrusions have to assume the positioning function of the long side direction of the beam component and the short side direction of the beam component, the pair of protrusions must have a certain strength. Therefore, the pair of protrusions need to be formed into a certain size. On the other hand, if the pair of protrusions are formed into a certain size, the freedom of the installation height of the beam component will be reduced, so that the installation height of the beam component can only be adjusted at a relatively large interval. In addition, if the pair of protrusions are formed in a certain size, when the installation height of the beam component is changed, the beam component and the pair of protrusions will collide, making it difficult to change the installation height of the beam component.

[0008] Therefore, an object of the present invention is to provide a modular frame in which the installation height of the beam member can be adjusted in smaller intervals and the installation height of the beam member can be adjusted very easily.

[0009] [Technical means to solve the problem]

[0010] The following invention solves the above-mentioned problem. That is, the combined frame (1) of the present invention includes a support member and a beam member. The support member has a first side surface and a second side surface adjacent to the first side surface, wherein the first side surface has a plurality of recesses arranged at equal intervals along the axial direction. The beam member has a first part and a second part, wherein the first part has a convex portion and faces the first side surface; the second part is arranged adjacent to the first part and faces the second side surface. Each of the recesses extends along the normal direction of the second side surface. The beam member is suitable for moving between a first position and a second position. In the first position, the beam member, in a state separated from the support member, faces the second part to the second side surface. In the second position, the beam member moves from the first position along the normal direction of the second side surface and is fixed to the support member by inserting the convex portion into one of the recesses.

[0013] The combined frame (4) of the present invention is also the combined frame as described in (3), wherein the first side has a protrusion at a position surrounded by the recesses and the second recesses, and when the beam component is located at the third position, the protrusion falling into the second recesses engages with the protrusion.

[0014] The combined rack (5) of the present invention is also a combined rack as described in (3) or (4), wherein the track includes a top surface, a first guide surface, and a second guide surface, wherein the first guide surface is adjacent to the top surface and is arranged on the first side surface, and the second guide surface is opposite to the first guide surface arranged adjacent to the top surface, and the second guide surface is inclined downward in a manner away from the first side surface.

[0015] The combined frame (6) of the present invention is also the combined frame as described in (5), wherein the saddle portion has a guided surface guided by the second guide surface, and the guided surface is inclined in a manner approaching the track as it moves upward.

[0016] The combined frame (7) of the present invention is also the combined frame as described in (5) or (6), wherein the beam component has a beam body extending along the normal direction of the first side surface, and the normal direction of the first side surface is consistent with the long side direction.

[0017] The combined frame (8) of the present invention is also the combined frame as described in (1) to (7), wherein the support member further has a first side surface, which is located opposite to the first side surface and adjacent to the second side surface.

[0036] With reference to the following drawings, an embodiment of the combined frame of the present invention will be described. The combined frame of the present invention is composed of a very small number of parts and is easy to assemble and disassemble. In addition, the installation height of the beam member can be adjusted at a finer interval, and the concave and convex shape is simple and easy to clean. In the following, the long side direction of the combined frame is L, the short side direction intersecting (orthogonal) with the long side direction L of the combined frame is S, and the height direction of the combined frame (the axial direction of the support member) is A for description.

[0037] [First embodiment]

[0038] like Figures 1 to 3 As shown, the combined frame 11 includes four pillar components 12, a plurality of connectors 13, a plurality of beam components 14, a foot 15 and a layer plate 16. The four pillar components 12 are arranged at the four corners of the combined frame 11. A plurality of rod-shaped connectors 13 are arranged along the short side direction S and connect the pillar components 12 together. A plurality of beam components 14 extend transversely along the long side direction L and span between the pillar components 12. The foot 15 is arranged at the lower end of the connector 13. The layer plate 16 spans between a pair of beam components 14.

[0039] like Figure 1 and Fig.15 As shown, the layer plate 16 has a pair of hook-shaped portions 17 at both ends in the short-side direction S, and the layer plate 16 is suitable for hooking with the pair of beam members 14. The layer plate 16 has a plurality of through holes 18. The through holes 18 extend in the short-side direction S, for example, in an elongated shape.

[0040] The upper and lower ends of the support member 12 are provided with connecting pieces 13, respectively. The connecting pieces 13 have the same shape as each other and extend in the lateral direction (horizontal direction).

[0041] like Figure 3 and Figure 4 As shown, each connector 13 is in the shape of a rectangular prism with a longitudinal section, and has a pair of insertion holes 21 at both ends. The prism-shaped insertion portions 22 provided at both ends of the support member 12 are inserted into these insertion holes 21, and the support members 12 can be easily connected to each other. The connector 13 is integrally formed of a resin material, but may also have a core material inside, such as a hollow square tube made of steel. In this case, the connector 13 can be manufactured, for example, by insert molding.

[0042] The foot 15 is connected to the connecting member 13 located at the lower end of the support member 12. Figure 4 As shown, the foot 15 is composed of a bolt 15A and a nut 15B, and the foot 15 can be adjusted according to the length extending from the connecting member 13. Of course, the foot 15 can also be set as a caster so that the combined frame 11 can be moved.

[0043] like Figures 1 to 4 As shown, the four support members 12 are arranged in the same manner. Each support member 12 extends in the vertical direction. The support member 12 has an insertion portion 22 at both ends in the axial direction A (up and down).

[0044] like Figures 4 to 6 As shown, the support member 12 is formed into a prism shape. The support member 12 is formed integrally from a resin material, but there may also be a core material inside, such as a hollow square tube made of steel, etc. In this case, the support member 12 can be manufactured, for example, by insert molding.

[0045] exist Figure 6 In order to make the structure of the assembly frame 11 easier to understand, the beam member 14 is rotated 180° compared to its actual position and is suspended in mid-air.

[0046] The support member 12 has a pair of opposing first side surfaces 23, a second side surface 24 adjacent to the first side surface 23, and a pair of rails 25 protruding from the second side surface 24. A normal direction 31 of the first side surface (a straight line direction perpendicular to the first side surface 23) is along the long side direction L of the assembly frame 11. A normal direction 32 of the second side surface (a straight line direction perpendicular to the second side surface 24) is along the short side direction S of the assembly frame 11. The second side surface 24 is perpendicular to either of the pair of first side surfaces 23. The support member 12 is bilaterally symmetrical.

[0047] Each of the pair of first side surfaces 23 has a plurality of recesses 33, a plurality of second recesses 34, and a protrusion 35. The plurality of recesses 33 are arranged at equal intervals relative to the axial direction A. The plurality of second recesses 34 extend downward from the bottom of the plurality of recesses 33. The protrusion 35 is slightly square and is arranged at a position surrounded by the recesses 33 and the second recesses 34. The recesses 33 extend in the lateral direction, that is, in the normal direction 32 of the second side surface (a direction orthogonal to the second side surface 24).

[0048] Each second recess 34 is connected to the bottom of the recess 33 (the end of the recess 33 opposite to the second side surface 24). The second recess 34 extends in the vertical direction (the axial direction A of the support member 12). Looking at the first side surface 23 from the front, the recess 33 and the second recess 34 form an "L" shape. The lower end of the second recess 34 is connected to the bottom of the recess 33 directly below. The shape of the lower end of the second recess 34 is not limited to this. For example, a protrusion extending along the normal direction 32 of the second side surface may be provided from the lower end of the protrusion 35 to separate the space between the lower end of the second recess 34 and the space directly below the recess 33.

[0049] The protrusion 35 has a square shape when the first side surface 23 is viewed from the front. The protrusion 35 is shaped so as to protrude by several millimeters from a portion including the recess 33 and the second recess 34. The protrusion 35 is formed so as to cross the first side surface 23 from a first guide surface 42 of the rail 25, which will be described below.

[0050] like Figure 6 As shown, a pair of rails 25 extend along the axial direction A of the pillar member 12. The pair of rails 25 are arranged at both ends of the second side surface 24 in the width direction. Each of the pair of rails 25 has a top surface 41, a first guide surface 42, and a plurality of second guide surfaces 43, wherein the first guide surface 42 is arranged on the first side surface 23 and adjacent to the top surface 41, and the plurality of second guide surfaces 43 are opposite to the first guide surface 42 arranged adjacent to the top surface 41.

[0051] The plurality of second guide surfaces 43 are arranged in series in the axial direction A of the support member 12 so as to correspond one-to-one to the plurality of recesses 33 arranged at fixed intervals in the axial direction A of the support member 12. Each of the plurality of second guide surfaces 43 moves away from the first side surface 23 when moving downward. Therefore, when the beam member 14 moves from the second position P2 to the third position P3, the second guide surfaces 43 can pull the beam member 14 in a direction closer to the first side surface 23 and position it.

[0052] like Figure 2 and Figure 3 As shown, a plurality of beam members 14 are formed in the same form as each other. The beam members 14 extend in the lateral direction (horizontal direction). The beam members 14 are formed integrally from a resin material, but the beam body 46 may also have a core material inside, such as a hollow square tube made of steel, etc., which will be described below. In this case, the beam members 14 can be manufactured, for example, by insert molding.

[0053] like Figure 6 and Figure 7 As shown, the beam member 14 has a first portion 44 facing the first side surface 23, a second portion 45 facing the second side surface 24, and a beam body 46 extending from the first portion 44 along the normal direction 31 of the first side surface. The first portion 44 and the second portion 45 are in an "L" shape when viewed from the axial direction A of the support member 12. The beam body 46 is formed in a prism shape with a longitudinal rectangular cross section.

[0054] The first portion 44 has a plurality of protrusions 47 and a plurality of hooks 53, wherein the plurality of hooks 53 extend laterally (horizontally) from the upper end of each of the plurality of protrusions 47. The first portion 44 has, for example, three protrusions 47 and three hooks 53. When the first portion 44 is viewed from the front, each protrusion 47 is square. The hooks 53 are formed integrally with the protrusions 47. The shapes of the protrusions 47 and the hooks 53 make them protrude from the rest of the first portion 44 by several millimeters. The intervals between the plurality of protrusions 47 are roughly equivalent to the intervals between the recesses 33.

[0055] like Fig.12 As shown, when the beam member 14 is located at the third position P3 , the hook 53 includes a portion hooked on the protrusion 35 of the support member 12 .

[0056] like Figure 6 As shown in FIG. 4 , the second portion 45 is plate-shaped. The second portion 45 has a saddle portion 51 that is saddle-shaped (arch-shaped in cross section). The saddle portion 51 extends along the axial direction A of the support member 12 and can span the rail 25. The saddle portion 51 has a plurality of guided surfaces 51A, which are guided by the second guide surface 43. Figure 6 , Figure 7 , Fig.13As shown in FIG. 1 and FIG. 2 , the guided surface 51A is inclined so that it approaches the rail 25 (the central axis C of the rail 25 ) when moving upward.

[0057] Next, the assembly method and function of the combined frame 11 of the embodiment of the present invention will be described. Figure 4 As shown, the operator connects the pair of support members 12 in the short-side direction S through a pair of connectors 13 to form a frame 52. In this process, the operator fixes the upper ends of the support members 12 to each other through the upper connector 13, and fixes the lower ends of the support members 12 to each other through the lower connector 13. In addition, the foot 15 is also connected to the lower connector 13. In this way, two frames 52 are formed.

[0058] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown in FIG. 1 , the operator needs to bridge the beam member 14 between the adjacent support members 12 along the longitudinal direction L. In this process, as shown in FIG. Figure 7 and Fig.10 As shown, the operator places the beam member 14 at the first position P1 , where the beam member 14 is separated from the support member 12 and the second portion 45 faces the second side surface 24 .

[0059] like Figure 7 and Figure 8 As shown in FIG. 1 , the operator moves the beam member 14 from its first position P1 to the second position P2 along the normal direction 32 (approximately the horizontal direction) of the second side surface, and fixes the beam member 14 to the support member 12 by inserting the protrusion 47 into one of the plurality of recesses 33. At this time, the saddle 51 of the second portion 45 of the beam member 14 will cross the track 25 of the support member 12. At this time, as shown in FIG. Fig.10 and Fig.11 As shown, the three protrusions 47 of the beam member 14 are to be inserted into the three recesses 33 of the support member 12. The operator should insert the protrusions 47 of the beam member 14 into the deepest part of the recesses 33 of the support member 12.

[0060] like Fig. 9 As shown in FIG. 1 , the beam member 14 inserted into the deepest part of the recess 33 of the support member 12 can be pushed down by hand or hit from above with a hammer or other tool to make it fall down. Fig.11 and Fig.12As shown, the convex portion 47 of the beam member 14 moves from the deep part of the concave portion 33 of the support member 12 to fall into the second concave portion 34. Thereby, the beam member 14 moves from the second position P2 to the third position P3. In addition, in the present embodiment, although the beam member 14 moves from the second position P2 to the third position P3 by pushing it in with hands or tools, this is not limited to this method, and the beam member 14 can also move from the second position P2 to the third position P3 by its own weight.

[0061] At this time, if Fig.12 As shown, the convex portion 47 dropped into the second concave portion 34 is engaged with the protrusion 35 of the pillar member 12. This means that when the beam member 14 is located at the third position P3, the beam member 14 is locked on the pillar member 12, and in this state the beam member 14 cannot fall off from the pillar member 12. In other words, if a moment acts on the beam member 14 in the direction from the second side 24 to the first side 23, the saddle portion 51 of the second portion 45 is caught on the rail 25, thereby preventing the beam member 14 from falling off from the pillar member 12. On the other hand, if a moment acts on the beam member 14 in the direction from the first side 23 to the second side 24, the convex portion 47 dropped into the second concave portion 34 is caught on the protrusion 35, thereby preventing the beam member 14 from falling off from the pillar member 12.

[0062] In this way, the combined frame 11 of the present embodiment locks the beam member 14 by moving from the second position P2 to the third position P3, so no separate fixing element is required to lock the beam member 14. This reduces the number of components and simplifies the overall structure of the combined frame 11. In addition, even if the combined frame 11 is subjected to vibration or the like when moving, the beam member 14 will not accidentally fall off from the support member 12.

[0063] When the beam member 14 moves from the second position P2 to the third position P3, the saddle 51 of the second portion 45 of the beam member 14 can slide along the rail 25 of the support member 12. This stabilizes the posture of the beam member 14 moving from the second position P2 to the third position P3 and prevents the beam member 14 from falling off from the support member 12 during the movement.

[0064] When the beam member 14 moves from the second position P2 to the third position P3, the beam member 14 is positioned relative to the support member 12 and firmly fixed to the support member 12 by the wedge effect between the second guide surface 43 of the rail 25 and the guided surface 51A of the saddle 51. The beam member 14 is positioned relative to the long side direction L of the assembly frame 11. In other words, Fig.13 and Fig.14 As shown, when the beam member 14 moves from the second position P2 to the third position P3 , the guided surface 51A of the beam member 14 is guided by the second guide surface 43 of the rail 25 .

[0065] At this time, the second guide surface 43 moves away from the first side surface 23 when moving downward, and the guided surface 51A is inclined, so the guided surface 51A moves toward the track 25 (the central axis C of the track 25) when moving upward, and the beam member 14 is attracted (pushed) to the first side surface 23 of the support member 12 under the action of the wedge effect. In this way, the beam member 14 is firmly fixed to the support member 12. In addition, the beam member 14 can be prevented from being deformed, and the beam member 14 can be correctly positioned with respect to the long side direction L of the assembly frame 11. In addition, it can also be prevented that the user accidentally drops the beam member 14 from the support member 12.

[0066] In this embodiment, the beam member 14 is only correctly positioned relative to the long side direction L, because the size of the long side direction L has a great influence and the deviation is easily detected. No special positioning is performed in the short side direction S, because the size has a small influence and the deviation is not easy to detect.

[0067] like Figure 2 As shown, after the beam member 14 is installed at a predetermined installation height, as shown in FIG. Fig.15 As shown, a layer plate 16 is installed between a pair of beam members 14. The layer plate 16 can be easily installed on the pair of beam members 14 by aligning a pair of hook-shaped portions 17 with the beam members 14 and placing the layer plate 16 on the beam members 14. Figure 1 As shown, the assembly of the modular frame 11 is completed by installing the layer plates 16 on all the beam members 14. The steps of disassembling the modular frame 11 can be reversed to the above steps.

[0068] If the installation height of the layer plate 16 is to be changed, the installation height of the layer plate 16 can be changed very conveniently by simply removing the layer plate 16 and appropriately changing the position of the beam component 14 relative to the support component 12.

[0069] Fig.16 A variation of the combined rack 11 is shown. In the variation of the combined rack 11, a left-right symmetrical support member 12 as described above can be used as a support for two combined racks 11. In other words, in the support member 12 located in the middle of the figure, the first side surface 23 located on the left and the track 25 located on the left are used to support the combined rack 11 on the left. Similarly, in the support member 12 located in the middle of the figure, the first side surface 23 located on the right and the track 25 located on the right are used to support the combined rack 11 on the right. In this way, the two combined racks 11 can be connected together for use. In addition, the number of combined racks 11 connected together is not limited to two, and an unlimited number of combined racks 11 can be connected if space permits.

[0070] According to this embodiment, the following description can be made. The combined frame 11 includes a support member 12 and a beam member 14. The support member 12 has a first side surface 23 and a second side surface 24, the first side surface 23 has a plurality of recesses 33 arranged at equal intervals relative to its axial direction A, and the second side surface 24 is adjacent to the first side surface 23. The beam member 14 has a first portion 44 and a second portion 45, the first portion 44 has a convex portion 47 and faces the first side surface 23, and the second portion 45 is arranged adjacent to the first portion 44 and faces the second side surface 24. Each of the plurality of recesses 33 extends along the normal direction 32 of the second side surface. The beam member 14 can move between a first position P1 and a second position P2, the first position P1 being when the beam member 14 is separated from the support member 12 and the second portion 45 faces the second side surface 24, and the second position P2 being when the beam member 14 moves from the first position P1 along the normal direction 32 of the second side surface, and the beam member 14 is fixed to the support member 12 by inserting the convex portion 47 into one of the plurality of recesses 33.

[0071] According to this structure, the beam member 14 can be fixed to the pillar member 12 in a one-touch manner by a simple structure of inserting the protrusion 47 into the first recess 33. This makes it very easy to change the installation height of the beam member 14. In addition, since the beam member 14 can be fixed by moving along the normal direction 32 of the second side surface, the recesses 33 can be set at smaller intervals, so that the installation height of the beam member 14 can be adjusted at smaller intervals. In addition, the combined structure of the protrusion 47 and the recess 33 is simple and easy to clean, and is suitable for use in food factories.

[0072] In this case, the first side surface 23 has a plurality of second recesses 34, each of which extends downward from the bottom of each of the plurality of recesses 33. The protrusion 47 can fall into the second recess 34 when in the second position P2, and thus the beam member 14 can move from the second position P2 to the third position P3 below the second position P2.

[0073] According to this structure, the convex portion 47 can fall into the second concave portion 34, and the beam member 14 can be moved from the second position P2 to the third position P3, so that the beam member 14 can be prevented from accidentally falling off the support member 12.

[0074] In this case, the support member 12 includes a rail 25 protruding from the second side surface 24 and extending in the axial direction A. The second portion 45 has a saddle 51 in a saddle shape extending in the axial direction A and capable of crossing the rail 25. When the beam member 14 moves from the second position P2 to the third position P3, the saddle 51 can slide along the rail 25.

[0075] According to this configuration, since the second portion 45 has the saddle portion 51 , when the beam member 14 moves from the second position P2 to the third position P3 , the saddle portion 51 can prevent the beam member 14 from falling off from the support member 12 .

[0076] The first side surface 23 has a protrusion 35 at a position surrounded by the recess 33 and the second recess 34 . When the beam member 14 is located at the third position P3 , the protrusion 47 dropped into the second recess 34 engages with the protrusion 35 .

[0077] According to this structure, when the beam member 14 is located at the third position P3, the beam member 14 can be prevented from falling off from the support member 12. In other words, when a moment acts on the beam member 14 in the direction from the second side surface 24 to the first side surface 23, the saddle portion 51 of the second portion 45 is caught on the rail 25, thereby preventing the beam member 14 from falling off from the support member 12. On the other hand, if a moment acts on the beam member 14 in the direction from the first side surface 23 to the second side surface 24, the convex portion 47 falling into the second concave portion 34 is caught on the protrusion 35, thereby preventing the beam member 14 from falling off from the support member 12.

[0078] The track 25 has a top surface 41, a first guide surface 42 and a second guide surface 43. The first guide surface 42 is adjacent to the top surface 41 and is located on the first side surface 23. The second guide surface 43 is opposite to the first guide surface 42 adjacent to the top surface 41. The second guide surface 43 is inclined away from the first side surface 23 when moving downward.

[0079] According to this structure, when the beam member 14 moves from the second position P2 to the third position P3, the second guide surface 43 acts like a wedge, pulling the beam member 14 toward the first side surface 23 of the pillar member 12. In this way, the beam member 14 can be positioned relative to the pillar member 12 and prevent the beam member 14 from making noise. The wedge effect can also firmly fix the beam member 14 to the pillar member 12. This can prevent the user from accidentally causing the beam member 14 to fall off the pillar member 12.

[0080] The saddle portion 51 has a guided surface 51A guided by the second guide surface 43 , and the guided surface 51A is inclined so as to approach the rail 25 when moving upward.

[0081] According to this structure, when the beam member 14 moves from the second position P2 to the third position P3, the guided surface 51A in addition to the second guide surface 43 acts like a wedge, pulling the beam member 14 toward the first side surface 23 of the support member 12. In this way, the beam member 14 can be positioned relative to the support member 12 and prevent the beam member 14 from making a noise. The additional effect of the above-mentioned wedge effect can make the beam member 14 more firmly fixed to the support member 12.

[0082] The beam member 14 has a beam body 46 extending along the normal direction 31 of the first side surface. The normal direction 31 of the first side surface coincides with the longitudinal direction L.

[0083] According to this structure, the beam member 14 can be positioned relative to the long side direction L of the combined frame 11. Therefore, according to the above configuration, generally speaking, the beam member 14 can be positioned relative to the long side direction L of the combined frame 11, and if positioning with a stricter standard is required, it can be positioned relative to the support member 12. On the contrary, in the present invention, since the short side direction S intersecting with the long side direction L is shorter in length, the influence of the misalignment in the short side direction S is smaller than that in the long side direction L. Therefore, the positioning in the short side direction is not important.

[0084] The support member 12 has an additional first side surface 23 at a position opposite to the first side surface 23 and adjacent to the second side surface 24. This structure allows the support member 12 to be bilaterally symmetrical, and the beam member 14 can be connected to the left and right sides of the support member 12. In this way, when two modular racks 11 are arranged adjacent to each other, the two modular racks 11 can share one support member 12, thereby reducing the number of support members 12 and reducing the cost of installing the modular racks 11 in factories or stores. In addition, by connecting a plurality of modular racks 11 in series, the rigidity of the modular racks 11 can be increased, thereby achieving a more stable modular rack 11.

[0085] The above embodiments can be implemented through various further replacements and changes. Of course, the above different embodiments can also be combined into one present invention according to actual conditions.
