[0001] The invention relates to a screw-free and rivet-free combined storage rack. Background Art

[0002] The screw-free and rivet-free modular rack can be randomly assembled to meet the needs of home interiors, offices and other occasions. Traditionally, there is a distinction between round columns (round tubes) and square columns (square tubes). If round tube columns are used, they cannot be assembled horizontally and cannot be effectively expanded. Therefore, it seems to be advantageous to use square tubes.

[0003] However, the storage rack formed by the traditional square tube column is usually fixed with rivets or screws, which is inconvenient to assemble and disassemble, and reduces the usability. In addition, the combination storage rack without screws and rivets has many accessories, which makes the assembly time-consuming, complicated and inconvenient, and further leads to the disadvantages of many production, processing and packaging processes and high costs.

[0004] Therefore, how to improve the problems encountered by conventional methods will be one of the issues that the industry needs to solve. Summary of the invention

[0006] The present invention provides a screw-free and rivet-free combined storage rack, comprising a plurality of column assemblies, at least one storage layer, and a plurality of connecting assemblies. Each column assembly comprises four plates, a plurality of trapezoidal holes, and at least one bent plate, and the four plates are connected together. The trapezoidal holes are penetrated through one of the four plates, and each bent plate is bent inside the corresponding trapezoidal hole. Each connecting assembly is respectively arranged at the corresponding storage layer, and these connecting assemblies are used to assemble the storage layer between these column assemblies. Each connecting assembly comprises at least one hook. The hook is inserted into the corresponding trapezoidal hole, and each hook is buckled into the corresponding trapezoidal hole along a vertical assembly direction.

[0007] In one embodiment, the trapezoidal hole has a first width and a second width along the vertical assembly direction, and the first width is greater than the second width.

[0008] In one embodiment, each of the bent plate members is an inclined member.

[0009] In one embodiment, the hook member includes a first hook member and a second hook member, and the first hook member is spaced apart from the second hook member by a setting distance.

[0010] In one embodiment, the connection assembly includes a fixed plate and a bent connection member, one side of the bent connection member is connected to the fixed plate, and the other side of the bent connection member is respectively connected to the hook member, and the hook member is separated from the fixed plate by a distance.

[0011] In one embodiment, the hook member is not parallel to the fixing plate member.

[0012] In one embodiment, the connection assembly includes a supporting member connected to and extending on one side of the bent connection member.

[0013] Based on the above, the screw-free and rivet-free combined storage rack of the present invention achieves the purpose of fast assembly and structural stability by virtue of the trapezoidal holes of the column components and the slope design of the hooks. Along the vertical assembly direction, the hooks are tightly engaged with the corresponding trapezoidal holes, thereby achieving fast assembly and structural stability.

Figures 1 to 4 The column assembly 110 of the present invention includes four plates, namely, a first plate 112, a second plate 116, a third plate 114, and a fourth plate 118, a plurality of trapezoidal holes G, namely, a first trapezoidal hole G1 and a second trapezoidal hole G2, and a first bent plate M1 and a second bent plate M2. The first plate 112 and the third plate 114 are parallel to each other, the second plate 116 and the fourth plate 118 are parallel to each other, the first plate 112 is connected to the second plate 116, the second plate 116 is connected to the third plate 114, the third plate 114 is connected to the fourth plate 118, and the fourth plate 118 is connected to the first plate 112. The four plates are connected together to form a square tube having a hollow portion PA. The trapezoidal hole G is provided in one of the four plates. For example, the trapezoidal hole G of the present invention is penetrated through the first plate 112. For the convenience of subsequent description, the first trapezoidal hole G1 and the second trapezoidal hole G2 are grouped together. The distance between each group of trapezoidal holes G and the next group of trapezoidal holes G is consistent, and they are arranged in order from top to bottom.

[0040] The first trapezoidal hole G1 has a top side GA and a bottom side GB along an upright assembly direction LC2, wherein the width of the first width H1 of the top side GA is greater than the width of the second width H2 of the bottom side GB, that is, the first trapezoidal hole G1 is a trapezoidal shape that is wide at the top and narrow at the bottom along the upright assembly direction LC2. Similarly, the second trapezoidal hole G2 is the same as the first trapezoidal hole G1. In addition, there is a first distance D1 between the top side GA of the first trapezoidal hole G1 and the top side GA of the second trapezoidal hole G2, there is a second distance D2 between the top side GA of the first trapezoidal hole G1 and the top side GA of the next first trapezoidal hole G1, and the distance between the second trapezoidal hole G2 and the first trapezoidal hole G1 above is less than the distance between the second trapezoidal hole G2 and the first trapezoidal hole G2 below.

[0041] The first bent plate M1 and the second bent plate M2 are bent inside the first trapezoidal hole G1 (and the second trapezoidal hole G2), respectively, and the first bent plate M1 and the second bent plate M2 extend from the first side GC and the second side GD of the first trapezoidal hole G1 and are bent to the inner surface of the first plate 112, respectively, so that the first bent plate M1 and the second bent plate M2 are located inside the hollow portion PA. For example, the first bent plate M1 and the second bent plate M2 are, for example, plates bent from the outer surface of the first plate 112 to the inside, respectively, and the first bent plate M1 and the second bent plate M2 have a protruding length K3.

[0042] The first bent plate M1 and the second bent plate M2 are inclined members to match the design of the trapezoidal hole G being wide at the top and narrow at the bottom. For example, the first bent plate M1 and the second bent plate M2 are arranged opposite to each other, and the distance K1 between the top end of the first bent plate M1 (close to the top side GA of the first trapezoidal hole G1) and the top end of the second bent plate M2 (close to the top side GA of the first trapezoidal hole G1) is greater than the distance K2 between the bottom end of the first bent plate M1 (close to the bottom side GB of the first trapezoidal hole G1) and the bottom end of the second bent plate M2 (close to the bottom side GB of the first trapezoidal hole G1).

Figure 6 Schematic diagram of the connection assembly of the present invention. Figure 7 for Figure 6 Schematic diagram of the connection component side. Figure 8 for Figure 6 See the diagram for the other side of the connection assembly. Figure 1 , Figures 5 to 8The storage layer 130 of the present invention includes a grid 132, two first cross bars 134, and two second cross bars 136, wherein the two first cross bars 134 are located at the front and rear sides of the grid 132, and the two second cross bars 136 are located at the left and right sides of the grid 132, and the length of the first cross bars 134 is greater than the length of the second cross bars 136. The connecting components 120 are arranged on both sides of the second cross bars 136, so that the four connecting components 120 are located at the four corners of the storage layer 130.

[0044] The connecting assembly 120 includes a fixed plate 122, a bent connecting member 124, a first hook member N1, a second hook member N2, and a supporting member 126, wherein the fixed plate 122 is fixed to both sides of the second cross bar 136, so that the connecting assembly 120 is assembled to the storage layer 130. One side of the bent connecting member 124 is connected to the fixed plate 122, and the other side of the bent connecting member 124 is connected to the first hook member N1 and the second hook member N2 to form a U-shaped member. The bent connecting member 124 is bent and extended from one side of the fixed plate 122, and the first hook member N1 and the second hook member N2 are bent and extended from one side of the bent connecting member 124, and the first hook member N1 and the second hook member N2 are separated by a setting distance ND. The supporting member 126 is connected and extended to one side of the bent connecting member 124, and the supporting member 126 is located between the first hook member N1 and the second hook member N2.

[0045] In one embodiment, the first hook member N1 and the second hook member N2 are designed as an inclined member. The first hook member N1 and the second hook member N2 are respectively separated from the fixed plate 122 by a distance. In addition, the first hook member N1 and the second hook member N2 are respectively not parallel to the fixed plate 122, so that the first hook member N1 and the second hook member N2 have an inclined angle A1 relative to the fixed plate 122. In other embodiments, the hook member may be one.

[0046] The following Figures 9 to 17 The assembly process is described below. For ease of explanation, Figures 9 to 16 Not drawn as Figure 1 The storage layer shown: First, Fig. 9 and Fig.10 , the connecting component 120 moves in an assembly direction LC1, and the assembly direction LC1 is toward the first trapezoidal hole G1 and the second trapezoidal hole G2 of the first plate 112 in the column component 110, and the position of the first hook N1 corresponds to the position of the first trapezoidal hole G1, and the position of the second hook N2 corresponds to the position of the second trapezoidal hole G2. Fig.11 and Fig.12As shown, the first hook member N1 is inserted into the first trapezoidal hole G1, and the second hook member N2 is inserted into the second trapezoidal hole G2. The abutment member 126 is located on the outer surface of the first plate member 112 in the column assembly 110, and the fixing plate member 122 is located on the outer surface of the second plate member 116 in the column assembly 110.

[0047] Then, if Fig.13 and Fig.14 As shown, the connecting component 120 is applied downward along the vertical assembly direction LC2, that is, the first hook member N1 is buckled in the first trapezoidal hole G1, and the second hook member N2 is buckled in the second trapezoidal hole G2. As the connecting component 120 is assembled downward along the vertical assembly direction LC2, since the first trapezoidal hole G1 and the second trapezoidal hole G2 are both trapezoidal hole designs with a wide top and a narrow bottom, the first hook member N1 and the second hook member N2 are designed with a slope, as shown in FIG. Fig.15 and Fig.16 As shown, as the first hook member N1 and the second hook member N2 move toward the vertical assembly direction LC2, the first hook member N1 and the second hook member N2 are pressed by the trapezoidal shape of the first trapezoidal hole G1 (or the second trapezoidal hole G2), which facilitates assembly, and through the structural shape matching, the connecting component 120 can be firmly assembled to the column component 110, and then as shown in FIG. Fig.17 As shown, the storage layer 130 is assembled to the column assembly 110 .

[0048] The first hook member N1 and the second hook member N2 are respectively against the first bent plate member M1, and the extension member N11 and the extension member N21 of the second hook member N2 are respectively disposed in the first plate member 112. Fig.16 As shown, there is still space between the first trapezoidal hole G1 and the second trapezoidal hole G2 for installing another connecting component 120. Fig.18 As shown, for the present invention as Figure 1 The screw-free and rivet-free combined storage rack 100 can be horizontally expanded and extended along the horizontal direction L1 for assembly, thereby increasing assembly convenience.

[0049] Fig.19 FIG. 4 is a schematic diagram of another viewing angle of the screw-free and rivet-free combined storage rack of the present invention. Fig. 20 This is a partial exploded schematic diagram of two column assemblies in the stacking direction of the present invention. Fig.19 and Fig. 20 ,in Fig.19 for Figure 1. The column assembly 110 can be divided into a first column assembly 110A and a second column assembly 110B along the stacking direction L2, and the second column assembly 110B is located above the first column assembly 110A. In one embodiment, a connector 140 can be used to combine the first column assembly 110A and the second column assembly 110B along the stacking direction L2 to achieve the required height of the screw-free and rivet-free modular storage rack 100. For example, the connector 140 includes a first protrusion 142 and a second protrusion 144, the first protrusion 142 is inserted into the first column assembly 110A, and the second protrusion 144 is inserted into the second column assembly 110B, wherein the first protrusion 142 has a hollow portion F1 to expose the first trapezoidal hole G1. The second protrusion 144 has a hollow portion F2 to expose the second trapezoidal hole G2.

[0050] In summary, the screw-free and rivet-free combined storage rack of the present invention achieves the purpose of fast assembly and structural stability by virtue of the trapezoidal holes of the column components and the slope design of the hooks, so that the hooks are tightly engaged with the corresponding trapezoidal holes along the vertical assembly direction.
