Description

Technical Field

[0001] The present invention relates to a storage rack, particularly a concave square tube storage rack.

Background Art

[0002] A prefabricated storage rack is a storage rack composed of a plurality of independent members (such as storage layers, connecting members, etc.) that can be assembled and used for storage. The design of prefabricated storage racks usually emphasizes flexibility and expandability, meeting the requirements of housing, offices, etc.

[0003] Conventionally, there is a distinction between round columns (round tubes) and square columns (square tubes). When using round tube columns, horizontal assembly in the lateral direction is not possible, and the storage rack cannot be effectively expanded in the lateral direction. Therefore, it is considered advantageous to use square tubes. However, the conventional square tube and storage rack structures have relatively complex structures, require time for assembly, have more production processing and packaging processes, and have the disadvantage of high costs.

The shelf board 130 is placed on the corresponding storage layer 120, and these three storage layers 120 and the shelf board 130 connected to them are assembled sequentially between the support column assemblies 110 along the stacking direction L11, thereby enabling the construction of various different combinations of concave rectangular tube storage racks 100.

[0029] Figure 3A is an explanatory diagram of the support assembly according to the present invention from one perspective. Figure 3B is a partial perspective view of the concave rectangular tube according to the present invention. Figure 3C is a partial explanatory diagram of the concave rectangular tube according to the present invention. Figure 3D is a partial side view of the concave rectangular tube according to the present invention. Referring to Figures 2 to 3D, the support assembly 110 of the present invention includes a concave rectangular tube 112 and a plurality of inclined holes MC. The concave rectangular tube 112 is a rectangular tube structure having a concave shape composed of a first plate 112A, a second plate 112B, a third plate 112C, and a plurality of concave plates GA. The present invention increases the structural strength of the support assembly 110 by changing the rectangular tube to a concave rectangular tube 112.

[0030] Both sides of the first plate 112A are connected to the second plate 112B and the third plate 112C, respectively, and the second plate 112B and the third plate 112C are parallel to each other, forming a three-sided structure, the second plate 112B is stretched and bent into a connecting plate 112D, the third plate 112C is stretched and bent into another connecting plate 112D, and both sides of the multiple concave plates GA are connected to the connecting plate 112D of the second plate 112B and the connecting plates 112C and 112E, respectively Connected to the plate, the first plate 112A, the second plate 112B, the third plate 112C, and multiple concave plates GA are connected to form a three-dimensional concave structure. The second plate 112B and the third plate 112C are on opposite sides, and the concave plates GA and the first plate 112A are on opposite sides. The concave rectangular tube 112 has a hollow section MB inside, and is a hollow tube. By combining multiple concave plates GA, the overall structural strength of the concave rectangular tube 112 is increased, and it can withstand external pressure and load. As an example in Figure 3A, there are five concave plates GA, and the number of concave plates GA can be adjusted according to the actual situation.

[0031] In one embodiment, the concave plate GA includes a recess 114A, a first plate portion 114B, and a second plate portion 114C. Both sides of the recess 114A are connected to the first plate portion 114B and the second plate portion 114C, the first plate portion 114B is connected to the connecting plate 112D of the second plate 112B, the second plate portion 114C is connected to the connecting plate 112E of the third plate 112C, and the recess 114A may be a recessed portion of the concave plate GA.

[0032] In one embodiment, the concave plate GA has inclinations on three surfaces, namely the first plate portion 114B, the second plate portion 114C, and the recess 114A, each having an inclined structure. As shown in Figure 3C, the first plate portion 114B has an inclination angle A1 with respect to the connecting plate 112D of the adjacent second plate 112B. Similarly, the second plate portion 114C has an inclination angle A1 with respect to the adjacent third plate 112C and connecting plate 112E. The inclination angle A1 increases along the assembly direction L12, and as shown in Figure 1, the assembly direction L12 is opposite to the stacking direction L11.

[0033] As shown in Figure 3A, there are multiple recessed plates GA, and each recessed plate GA is fitted with one inclined hole assembly BS. For example, an inclined hole assembly BS is fitted into the recess 114A of a recessed plate GA, and the inclined hole assembly BS has two sets of inclined holes, a first set of inclined holes B1 and a second set of inclined holes B2. The first set of inclined holes B1 and the second set of inclined holes B2 are provided side by side and penetrate the recess 114A of the recessed plate GA, and each of the first set of inclined holes B1 and the second set of inclined holes B2 has two inclined holes MC along the assembly direction L12, so the inclined hole assembly BS of the recessed plate GA in this embodiment has four inclined holes MC.

[0034] In one embodiment, the inclined hole MC is given an inclined structure to penetrate the inclined structure of the first plate portion 114B and the second plate portion 114C and cover a part of the position of the inclined hole MC. In another embodiment, the inclined hole can be provided so as to have an inclination angle with respect to the first plate portion or the second plate portion, that is, the inclined hole itself is an angled hole (Angled Hole or Slanted Hole), and the angled hole is a hole that is not parallel to the surface of the first plate portion 114B or the second plate portion 114C in its longitudinal direction, but is drilled at an angle at a certain angle.

[0035] On the other hand, taking Figure 3D as an example, along the assembly direction L12, the recess 114A has an inclination angle A2 with respect to the front end of the concave rectangular tube 112 (such as the connecting plate 112D of the second plate 112B), and along the assembly direction L12, the inclination angle A2 becomes increasingly larger.

[0036] Figure 4A is a perspective view illustrating a shelf attached to a first assembly member according to the present invention. Figure 4B is a perspective view illustrating a shelf attached to a second assembly member according to the present invention. Figure 4C is a side view illustrating a shelf attached to a first assembly member according to the present invention. Figure 4D is a side view illustrating a shelf attached to a first assembly member according to the present invention from a different angle. Referring to Figures 2, 4A to 4D, the storage layer 120 of the present invention includes a shelf 122, two first assembly members 124, and two second assembly members 126. The shelf 122 is a long frame and includes a first cross member 122A, a second cross member 122B, a third cross member 122C, and a fourth cross member 122D. The extension direction of the first cross member 122A is parallel to the extension direction of the third cross member 122C, and there is a distance between the first cross member 122A and the third cross member 122C. The extension direction of the second cross member 122B is parallel to the extension direction of the fourth cross member 122D, and there is a distance between the second cross member 122B and the fourth cross member 122D. Both ends of the first cross member 122A are connected to the second cross member 122B and the fourth cross member 122D, and both ends of the third cross member 122C are connected to the second cross member 122B and the fourth cross member 122D, forming a long frame as shown in Figure 2. The left and right sides of the shelf 122 are the second cross member 122B and the fourth cross member 122D, respectively, and the front and rear sides of the shelf 122 are the third cross member 122C and the first cross member 122A, respectively.

[0037] In this embodiment, the two first assembly members 124 and the two second assembly members 126 are each provided at the positions of the cross members corresponding to the shelf 122, and the first fastener 124B of the first assembly member 124 and the second fastener 126B of the second assembly member 126 are located on the left and right sides of the shelf 122. For example, the first assembly member 124 is installed on the second cross member 122B and the fourth cross member 122D, and the second assembly members 126 are installed at both ends of the first cross member 122A. One side of the second assembly member 126 is installed on the first cross member 122A, and the second fastener 126B of the second assembly member 126 is located on the outside of the second cross member 122B, straddling the second cross member 122B. Since the left and right sides of shelf 122 are the second cross member 122B and the fourth cross member 122D, respectively, the second fastener 126B of the second assembly member 126 also straddles the fourth cross member 122D and is located on the outside of the fourth cross member 122D.

[0038] The first assembly member 124 of this embodiment includes a first body 124A, two first fasteners 124B, and at least one rib 124C. The first body 124A has a Z-shaped hook structure, the first fasteners 124B are fasteners with a Z-shaped hook structure, and the rib 124C is provided on the outer surface of the first body 124A and can increase the strength of the first assembly member 124. The first body 124A includes a first fixing member C1 and a fastener connecting member C2. The first fixing member C1 is a plate, and the first fixing member C1 is fixed to the surface of the second cross member 122B of the shelf 122, and the first assembly member 124 can be provided on the second cross member 122B. Similarly, the first fixing member can be fixed to the outer surface of the fourth cross member of the shelf, and the first assembly member 124 can be provided on the fourth cross member 122D.

[0039] The fastener connecting member C2 connects the two first fasteners 124B to the first fixing member C1, and the fastener connecting member C2 is a plate bent from one side of the first fixing member C1, and the two first fasteners 124B are each connected to different positions on the fastener connecting member C2, and there is a distance between the two first fasteners 124B and the surface of the second cross member 122B, that is, the two first fasteners 124B are not in contact with or connected to the surface of the second cross member 122B.

[0040] In one embodiment, the inner surface of the first fastener 124B is an inclined surface SA1, that is, the fastener of the present invention has an inclined surface and an inclined structure. The inclined surface SA1 of the first fastener 124B has a fastener inclination angle A3 with respect to the fastener connecting member C2. Also, taking Figure 4D as an example, the fastener connecting member C2 has a fastener structure inclination angle A4 with respect to the first fixing member C1, that is, the fastener connecting member C2 has an inclined structure. Since the fastener connecting member C2 connects these two first fasteners 124B, these two first fasteners 124B also have a fastener structure inclination angle A4 with respect to the fastener connecting member C2.

[0041] The second assembly member 126 of this embodiment includes a second body 126A, two second fasteners 126B, and at least one rib 126C. The second body 126A has an L-shaped hook structure, and the second fasteners 126B are fasteners with an L-shaped hook structure. The rib 126C can be provided on the outer surface of the second body 126A, and can increase the strength of the second assembly member 126. The second body 126A includes a second fixing member D1 and a fastener connecting member D2. The second fixing member D1 is a plate, and the second fixing member D1 is fixed to the surface of the first cross member 122A of the shelf 122, and the second assembly member 126 is provided on the first cross member 122A.

[0042] The fastener connecting member D2 connects the two second fasteners 126B to the second fixing member D1, and the fastener connecting member D2 is a plate bent from one side of the second fixing member D1, and the two second fasteners 126B are each connected to different positions on the fastener connecting member D2, and there is a distance between the two second fasteners 126B and the surface of the second cross member 122B, that is, the two second fasteners 126B are not in contact with or connected to the surface of the second cross member 122B.

[0043] Since the structure of the second fastener 126B is similar to that of the first fastener 124B, the inner surface of the first fastener 124B in Figure 4C is a sloped surface SA1, and the fastener connecting member C2 in Figure 4D has a fastener structure inclination angle A4 with respect to the first fixing member C1, and this can also be applied to the structure of the second fastener 126B.

[0044] From the above, it can be seen that the fasteners for the storage layer 120 of the present invention are provided on the shelf 122, and the fasteners are divided into, for example, a first fastener 124B and a second fastener 126B, the first assembly member 124 is installed on the first fastener 124B, the second assembly member 126 is installed on the second fastener 126B, and the number and installation configuration of the fasteners can be adjusted according to the actual situation.

[0045] Figure 5 is a perspective view showing the process of assembling the storage layer according to the present invention to the support column assembly. Figures 6 and 7 are perspective views showing the process of attaching the first assembly member according to the present invention to the inclined hole, respectively. Figure 8 is a perspective view showing the first assembly member according to the present invention engaged with the inclined hole.

[0046] First, referring to Figure 5, in this embodiment, the process of assembling the storage layer 120 to these four support column assemblies 110 involves first moving the storage layer 120 in the direction of movement L3, where movement L3 is horizontal movement or movement in the direction of the concave plate GA of the concave rectangular tube 112.

[0047] Next, as shown in Figures 6 and 7, the two first fasteners 124B within the first assembly member 124 move toward the concave plate GA of the concave rectangular tube 112, gradually moving the two first fasteners 124B closer to the positions of the two inclined holes MC until the two first fasteners 124B are positioned within the corresponding inclined holes MC.

[0048] Next, the storage layer 120 continues to move along the assembly direction L12, moving the two first fasteners 124B downwards from the inclined hole MC until the two first fasteners 124B engage with the inclined hole MC on the left side of the concave plate GA, as shown in Figure 8, thereby securing the first assembly member 124 of the storage layer 120 to the concave rectangular tube 112 of the support assembly 110.

[0049] Furthermore, in the present invention, as shown in Figure 4D, the fastener connecting member C2 has a fastener structure inclination angle A4 with respect to the first fixing member C1, and the inclined structure of the fastener connecting member C2 along the assembly direction L12 can be fastened together with the inclined structure of the inclined hole MC.

[0050] Furthermore, as shown in Figure 4C, the inner surface of the first fastener 124B is an inclined surface SA1, and the first fastener 124B itself has an inclined structure. The inclined structure of the first fastener 124B is fitted into the inclined hole MC and fastened, improving stability.

[0051] At the same time, the two second fasteners 126B of the second assembly member 126 in Figure 4B can be fitted with the description of the first fastener 124B described above, and the two second fasteners 126B can be engaged with the inclined hole MC on the left side of the concave plate GA, thereby fixing the second assembly member 126 of the storage layer 120 to the concave rectangular tube 112 of the support assembly 110.

[0052] Thus, as shown in Figure 1, the storage layer 120 of the present invention is fixed between these four support column assemblies 110 by engaging these fasteners (for example, the first fastener 124B and the second fastener 126B) of the storage layer 120 with the inclined holes MC of the concave plate GA. Next, the shelf board 130 is placed on top of the storage layer 120, positioning the shelf board 130 between these support column assemblies 110.

[0053] Next, the storage layer 120 and the shelves 130 are sequentially installed between the support columns 110 along the stacking direction L11 to form the concave rectangular tube storage rack 100 as shown in Figure 1.

[0054] Furthermore, the concave plates GA at different positions on the concave rectangular tube 112 allow the storage layer 120 to be moved, disengaging the fasteners of the storage layer 120 (e.g., the first fastener 124B and the second fastener 126B) from the inclined holes MC of the concave plates GA, and, depending on the situation, engaging the fasteners of the storage layer 120 (e.g., the first fastener 124B and the second fastener 126B) with the inclined holes MC of the concave plates GA at different positions to adjust and raise or lower the storage layer 120.

[0055] Figure 9 is a perspective view of one embodiment of the process by which two storage layers according to the present invention are attached to a concave rectangular tube. Figure 10 is a perspective view of one embodiment of the process by which the inclined holes of the support assembly according to the present invention are engaged. First, refer to Figures 3A, 9, and 10. Each concave plate GA has an inclined hole set BS, and the inclined hole set BS has two sets of inclined holes, a first set of inclined holes B1 and a second set of inclined holes B2, and the first set of inclined holes B1 and the second set of inclined holes B2 each have two inclined holes MC installed along the assembly direction L12, so that the inclined hole set BS on the concave plate GA of this embodiment has four inclined holes MC, the first set of inclined holes B1 which can be assembled to the left side of the same concave rectangular tube 112, and the second set of inclined holes B2 which can be assembled to the right side of the concave rectangular tube 112, that is, adjacent storage layers 120 and 120A can share the concave rectangular tube 112, and the storage layers 120 and 120A can be combined and arranged side by side, thus providing an aesthetically pleasing appearance and saving costs.

[0056] Furthermore, taking the first assembly member 124 as an example, in other embodiments, the second assembly member 126 shown in Figure 4B can also be engaged with the corresponding inclined hole MC using the above method, allowing adjacent storage layers 120 and 120A to share the concave rectangular tube 112, and enabling the storage layers 120 and 120A to be combined and arranged side by side.

[0057] Figure 11 is a perspective view of another embodiment of the concave rectangular tube storage rack according to the present invention. Referring to Figure 11, the concave rectangular tube storage rack 200 of the present invention includes a plurality of column assemblies 210, five storage layers 220, and five shelves 230. The number of storage layers 220 and shelves 230 may be multiple, and the shelves 230 may be in a grid. Figure 11 has a total of four column assemblies 210. There is a distance between two column assemblies 210 located at the front, and also a distance between two column assemblies 210 located at the rear, and the front and rear two column assemblies 210 are similarly spaced apart, and these column assemblies 210 are arranged in a rectangle or any shape. The shelves 230 are provided on the corresponding storage layers 220, and these five storage layers 220 and the shelves 230 connected to them are assembled sequentially between the column assemblies 210 along the stacking direction L11, so that a variety of different concave rectangular tube storage racks 200 can be constructed.

[0058] Figure 12 is a partial perspective view illustrating the concave rectangular tube in Figure 11 according to the present invention. Referring to Figures 11 and 12, the support assembly 210 of the present invention includes a concave rectangular tube 212 and a plurality of inclined holes MC2. The concave rectangular tube 212 is a rectangular tube structure having one concave shape, composed of a first plate 212A, a second plate 212B, a third plate 212C, and a concave plate GA2. The present invention increases the structural strength of the support assembly 210 by changing the rectangular tube to a concave rectangular tube 212. The difference between the support assembly 210 in Figure 12 and the support assembly 110 in Figure 3B is that the number of concave plates GA2 is one, i.e., the concave plate GA2 is a single plate, whereas the difference from Figure 3B is that the number of concave plates GA is multiple.

[0059] Both sides of the first plate 212A are connected to the second plate 212B and the third plate 212C, respectively, and both sides of the concave plate GA2 are connected to the second plate 212B and the third plate 212C, respectively. The first plate 212A, the second plate 212B, the third plate 212C, and the concave plate GA2 are connected to form a three-dimensional concave structure. The second plate 212B and the third plate 212C are on opposite sides, and the concave plate GA2 and the first plate 212A are on opposite sides. The concave rectangular tube 212 has a hollow section MB2 inside, making it a hollow tube. Together with the concave plate GA2, the structural strength of the entire concave rectangular tube 212 is increased, allowing it to withstand external pressure and load.

[0060] In one embodiment, the concave plate GA2 includes a recess 212D, a first plate portion E1, and a second plate portion E2. Both sides of the recess 212D are connected to the first plate portion E1 and the second plate portion E2, the first plate portion E1 is connected to the second plate 212B, the second plate portion E2 is connected to the third plate 212C, and the recess 212D may be a recessed portion of the concave plate GA2.

[0061] As shown in Figure 12, there is one concave plate GA2, and multiple inclined hole assemblies BS2 are installed on this single concave plate GA2. For example, the recess 212D of the concave plate GA2 is fitted with multiple inclined hole assemblies BS2 arranged along the assembly direction L12, and each inclined hole assembly BS2 has two sets of inclined holes, a first set of inclined holes B12 and a second set of inclined holes B22. The first set of inclined holes B12 and the second set of inclined holes B22 are arranged side by side and penetrate the recess 212D in the concave plate GA2, and each of the first set of inclined holes B12 and the second set of inclined holes B22 has two inclined holes MC2 along the assembly direction L12, so that the inclined hole assemblies BS2 on the concave plate GA2 in this embodiment have four inclined holes MC2.

[0062] The inclined hole MC2 has an inclined structure. The inclined hole MC2 has an inclination angle A5 relative to the adjacent plate portion (such as the second plate portion E2 or the first plate portion E1), meaning that the inclined hole MC2 itself is an oblique hole, and the longitudinal direction of the inclined hole MC2 is not parallel to the surface of the first plate portion E1 or the second plate portion E2, but is a hole that has been excavated obliquely at a certain angle.
