Description

[Technical Field]

[0001] The present invention relates to a storage cabinet, and more particularly to a foldable storage cabinet that can be folded to reduce its volume for convenient storage. [Background technology]

[0002] Currently, the most common storage case structure consists of a case body and a case lid. Because the case body has a fixed structure, it cannot be folded at will, occupying a lot of space and making it inconvenient for storage, transportation, and use. Lockers are widely used and can be found in almost every office and home, both domestically and internationally. Current locker designs are primarily based on the individual needs of users and environments, and there are few universal lockers. As a result, lockers are specific and limited (e.g., student lockers, home clothing lockers, refrigerated lockers, etc.) and can only be used in certain locations. However, as people's demands for living space increase, a few large lockers alone are no longer sufficient to meet their needs. Therefore, several convenient small lockers (e.g., small children's lockers, small plastic lockers, etc.) have emerged. Furthermore, many supermarkets and entertainment facilities have further designed automatic lockers to facilitate the convenience of customers' items. While these designs meet the requirements for use in certain environments, these lockers still occupy a large amount of space when not in use, making the problem even more pronounced in space-constrained environments (e.g., homes). Summary of the Invention [Problem to be solved by the invention]

The state after the above parts have been assembled is as shown in FIG. As described above, in one embodiment, the bottom pivot portion 1011 and the top pivot portion 1012 may not be molded into the back plate 101 but may be molded into the housing 103 at the same time, or the bottom pivot portion 1011 may be molded into the back plate 101 and the top pivot portion 1012 may be molded into the housing 103, or the bottom pivot portion 1011 may be molded into the housing 103 and the top pivot portion 1012 may be molded into the back plate 101.

[0025] As described above, the bottom pivot 1011 may be molded into the bottom of one of the housing 103 and back plate 101, and the top pivot 1012 may be molded into the top of the second of the housing 103 and back plate 101. In one embodiment, when the first of the housing 103 and back plate 101 is the same as the second of the housing 103 and back plate 101, the top pivot 1012 and the bottom pivot 1011 are both located on the same one of the housing 103 and back plate 101. That is, the top pivot 1012 and the bottom pivot 1011 are molded into the back plate 101 or the housing 103 at the same time. In another embodiment, when the first of the housing 103 and the back plate 101 is different from the second of the housing 103 and the back plate 101, the top pivot 1012 is located on one of the housing 103 and the back plate 101, and the bottom pivot 1011 is located on the other of the housing 103 and the back plate 101. That is, the bottom pivot 1011 can be molded into the back plate 101 and the top pivot 1012 can be molded into the housing 103, or the bottom pivot 1011 can be molded into the housing 103 and the top pivot 1012 can be molded into the back plate 101, but the invention is not limited thereto. In one embodiment, the first cover plate pivot portion 1052 of the cover plate 1051 is provided corresponding to the top pivot portion 1012, so that when the top pivot portion 1012 is provided on the housing 103, the first cover plate pivot portion 1052 of the cover plate 1051 is provided toward the top pivot portion 1012 of the housing 103. In one embodiment, the bottom plate pivot portion 1041 of the bottom plate 104 is provided corresponding to the bottom pivot portion 1011, so that when the bottom pivot portion 1011 is provided on the housing 103, the bottom plate pivot portion 1041 of the bottom plate 104 is provided toward the bottom pivot portion 1011 of the housing 103.

[0026] In one embodiment, the housing 103 and the back panel 101 may both have a bottom pivot 1011, and the bottom panel pivot 1041 may be optionally pivotally attached to the bottom pivot 1011 of the housing 103 or the back panel 101. The folding direction of the bottom panel 104 is determined by the pivot object of the bottom panel pivot 1041. In one embodiment, the housing 103 and the back panel 101 may both have a top pivot 1012, and the first cover panel pivot 1052 may be optionally pivotally attached to the top pivot 1012 of the housing 103 or the back panel 101, and the folding direction of the cover panel 1051 is determined by the pivot object of the first cover panel pivot 1052.

[0027] 3, which is a schematic diagram of the opening and closing of the top and door panels of a folding storage cabinet, in which a storage space 107 is formed inside the folding storage cabinet 10 shown in FIG. 3. When the top panel 105 opens relative to the back panel 101, a user can place items on the bottom panel 104 within the storage space 107 from above the folding storage cabinet 10. When the door panel 106 opens relative to the housing 103, a user can also place items on the bottom panel 104 within the storage space 107 from the front of the folding storage cabinet 10. Of course, the top panel 105 and the door panel 106 can also be opened simultaneously to put items in and take them out.

[0028] Referring to Figure 4, which is a schematic diagram of the top panel folding, and also referring to Figure 2, two wings 1054 are pivotally attached to both sides of the cover plate 1051 of the top panel 105 shown in Figure 2, and the top panel 105 is normally abutted against the two folding side panels 102 by the two wings 1054, so that the top panel 105 normally has a width H1 before the two wings 1054 are folded. The two wings 1054 can be opened, closed, and folded relative to the cover plate 1051, so that after the two wings 1054 are folded relative to the cover plate 1051, the top panel 105 has a width H2. Comparing width H1 and width H2, it can be seen that width H2 is clearly smaller than width H1. 5, which is a schematic diagram of the top panel 105 being folded. As shown in FIG. 4, when folding storage cabinet 10 is folded for storage when not in use, the two wings 1054 of top panel 105 are first folded relative to cover panel 1051, forming width H2 on top panel 105. As a result, the two wings 1054 are folded, and the entire top panel 105 is folded relative to back panel 101, and then overlaps with back panel 101, allowing top panel 105 to be folded into storage space 107. Referring to FIG. 6, which is a schematic diagram of the bottom panel being folded. As shown in FIG. 5, bottom panel 104 is normally pivotally attached to back panel 101, and both sides of bottom panel 104 abut against two folding side panels 102. Therefore, when folding the bottom plate 104, a force can be applied from the bottom of the bottom plate 104 to push the bottom plate 104 upward, so that the bottom plate 104 is folded relative to the back plate 101 and overlaps the back plate 101. It should be noted that the folding order of the top plate 105 and the bottom plate 104 is merely exemplary, and it is not necessarily the case that the top plate 105 must be folded after the bottom plate 104 is folded so that the top plate 105 covers the bottom plate 104, as shown in the figure. Referring to FIG. 2, in one embodiment, the back plate 101 has a bottom surface A, an upper surface B, and a lower surface C, and the top pivotal connection 1012 is located on the upper surface B and the bottom pivotal connection 1011 is located on the lower surface C.If the distance between the top pivot part 1012 and the bottom surface A is greater than the distance between the bottom pivot part 1011 and the bottom surface A, when folding the top plate 105 and the bottom plate 104, the bottom plate 104 must be folded first and then the top plate 105 so that the top plate 105 and the bottom plate 104 are sequentially stored in the storage space formed by the bottom surface A, upper surface B, and lower surface C of the back plate 101. If the distance between the top pivot part 1012 and the bottom surface A is less than the distance between the bottom pivot part 1011 and the bottom surface A, when folding the top plate 105 and the bottom plate 104, the top plate 105 must be folded first and then the bottom plate 104 so that the top plate 105 and the bottom plate 104 are sequentially stored in the storage space formed by the bottom surface A, upper surface B, and lower surface C of the back plate 101. In other words, to ensure that the top panel 105 and the bottom panel 104 are fully accommodated in the accommodation space of the back panel 101 and do not affect the folding of the folding side panel 102, the distance between the top pivot 1012 and the bottom surface A must not be equal to the distance between the bottom pivot 1011 and the bottom surface A, and the difference between the two distances must be greater than at least one difference threshold. The difference threshold may be the thickness of the last folded element of the top panel 105 or the bottom panel 104. For example, if the top panel 105 is folded after the bottom panel 104 is folded, the difference threshold may be the thickness of the wing panels 1054 of the top panel 105 in the folded state. If the bottom panel 104 is folded after the top panel 105 is folded, the difference threshold may be the thickness of the bottom panel 104. In one embodiment, when the top pivot 1012 is molded into the housing 103 at the same time as the bottom pivot 1011, the housing 103 may have a bottom surface, an upper surface, and a lower surface, and the distance between the top pivot 1012 and the bottom surface of the housing 103 is different from the distance between the bottom pivot 1011 and the bottom surface of the housing 103 to avoid the top panel 105 and the bottom panel 104 from affecting the folding of the folding side panels 102. In yet another embodiment, if the height of the back panel 101 is greater than the sum of the lengths of the bottom panel 104 and the top panel 105, i.e., if the top panel 105 and the bottom panel 104 do not overlap after being folded, the distance between the top pivot 1012 and the bottom surface A may be equal to the distance between the bottom pivot 1011 and the bottom surface A.

[0039] Below are the verification results after reinforcing the bottom board and shelf boards.

[0040] Next, an experiment was conducted using embodiment 1 and comparative example 1, and a pressure resistance experiment was conducted on the side plates of embodiment 1 of the present invention and comparative example 1. A weight of 30 kg was applied to the bottom plate of embodiment 1 (i.e., the bottom plate 104 of the present invention will be referred to as bottom plate 200 hereinafter) and the bottom plate 300 of comparative example 1, and the results were analyzed using a computer-aided engineering (CAE) simulation calculation method. The results are shown in (a) (i.e., embodiment 1) and (b) (i.e., comparative example 1) of Figure 26. The difference between the bottom plate 300 of Comparative Example 1 and the bottom plate 200 of Embodiment 1 is that the bottom plate 300 of Comparative Example 1 does not include the overall reinforcing structure included in the reinforcing structure 1042 of the present invention. Table 1 shows the maximum deformation values obtained in the first embodiment and the first comparative example. [Table 1] As can be seen from Table 1, the maximum deformation value of the bottom plate 300 in Comparative Example 1 is 1.98 times the maximum deformation value of the bottom plate 200 in Embodiment 1. Therefore, it can be seen that in Embodiment 1, the maximum deformation value of the bottom plate 200 is lower than in Comparative Example 1, and pressure resistance is effectively improved. Pressure resistance experiments were conducted on the shelf boards of embodiment 1 of the present invention and comparative example 1, and a weight of 15 kg was applied to the shelf board of embodiment 1 (i.e., shelf board 108 of the present invention will be referred to as shelf board 400 hereinafter) and the shelf board 500 of comparative example 1, respectively, and the results of analysis using a CAE simulation calculation method are shown in Figure 27 (a) (i.e., embodiment 1) and (b) (i.e., comparative example 1). The difference between shelf board 500 of Comparative Example 1 and shelf board 400 of Embodiment 1 is that shelf board 500 does not include the overall reinforcing structure included in reinforcing structure 1082 of the present invention. Table 2 shows the maximum deformation values obtained in the first embodiment and the first comparative example. [Table 2] As can be seen from Table 2, the maximum deformation value of shelf 500 in Comparative Example 1 is 1.28 times the maximum deformation value of shelf 400 in Embodiment 1. This shows that in Embodiment 1, the maximum deformation value of shelf 400 is lower than in Comparative Example 1, and pressure resistance is effectively improved.

[0041] 28 and 29, which show another embodiment (10) of the present invention, in which at least one or more fixing portions 1047 are molded on two opposite sides of the bottom plate 104 shown in FIGS. 28 and 29, and the fixing portions 1047 may be molded into hook members. The first side plate 1025 and the second side plate 1026 each have at least one or more relative fixing portions 1029 molded on one side of these fixing portions 1047, and the relative fixing portions 1029 may be molded into a hook groove-like structure for fixing the fixing portions 1047, so as to provide stable support when a heavy object is placed on the bottom plate 104 after the bottom plate 104 is fixed to the relative fixing portions 1029 by the fixing portions 1047.

[0042] 30 and 31, which show another embodiment (eleventh) of the present invention, in which at least one or more locking devices 1085 are molded on two opposing sides of the shelf 108 shown in Figures 30 and 31, and locking device fixing grooves 1040 are molded in the housing 103 at positions corresponding to the locking devices 1085, and the shelf 108 can be fixed to these locking device fixing grooves 1040 by these locking devices 1085 when not in use so that the shelf 108 stands upright relative to the housing 103 for convenient storage. In one embodiment, at least one of these locking devices 1085 can further be molded with a protrusion 1086 that can improve the tightness with which the locking device 1085 is fitted into the locking device fixing groove 1040, so that the shelf 108 can be more firmly fixed to the housing 103.

[0043] 32 to 34, which show another embodiment (twelfth) of the present invention. Referring also to FIGS. 1, 5 and 17, at least one or more anti-bending members 10251 and at least one or more abutment pins 10261 are molded on the same side as the third side panel pivot portion 1027 and the fourth side panel pivot portion 1028 of the first side panel 1025 and the second side panel 1026 shown in FIG. 32, and an arc-shaped groove 10252 for abutting the abutment pin 10261 is molded in the anti-bending member 10251. After the first side panel 1025 and the second side panel 1026 are connected, the abutment pin 10261 is forced to fit into the slot 10252 of the anti-bending member 10251. Thus, when the top panel 105, bottom panel 104, and shelf panel 108 of the foldable storage cabinet 10 are all retracted and the storage space 107 of the foldable storage cabinet 10 is not supported by any object, the abutment pin 10261 fits into the slot 10252 of the anti-bending member 10251, and the first side panel 1025 and the second side panel 1026 are connected together, thereby providing better anti-bending capability. That is, as shown in FIG. 34 , when the storage space 107 is not supported by any object, the first side panel 1025 and the second side panel 1026 are prevented from being bent or deformed by a small external force.
