Description

[0001] This application claims priority to Chinese Patent Application No. 2024208433823, filed on April 22, 2024, entitled "A Storage Box", the contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to a storage box, and more specifically, to a storage box with an improved latch. Background Technology

[0003] Molded plastic storage boxes are known. Current storage boxes have each side panel hinged to the base, and the side panels can selectively move around the hinge between a use position substantially perpendicular to the base and a folded position parallel to the base. Adjacent side panels are joined at corners using any of a variety of methods to selectively lock the storage box in the use position. When not in use, the side panels move to the folded position to save space. However, when in the folded position, existing storage boxes tend to have side panels detach from the base, increasing the likelihood of damage from impacts during transport.

[0004] Furthermore, existing storage boxes typically use a top opening and a lid for access. However, when multiple boxes are stacked, the lid cannot be opened directly due to the obstruction at the bottom of the upper box, making access difficult. To overcome this drawback, existing improvements have added side openings and side doors to the storage boxes. These side doors can be opened or closed by rotation, selectively opening or closing the side openings. However, existing side doors generally use a simple locking structure with insufficient locking force, resulting in unstable closure and easy opening under slight external force. This leads to poor locking reliability and low security performance. Utility Model Content

[0031] In the following description, different embodiments of this application will be described. Specific structures and details are presented for illustrative purposes to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that this application can be implemented without these specific details. Furthermore, well-known features will be omitted or simplified to make the described embodiments clear.

[0032] Referring now to the accompanying drawings, in which the same reference numerals denote the same parts in several views. Figure 1 A perspective view of a storage box 10 according to one embodiment is shown. Figure 2 An exploded view of the storage box 10 is shown. The storage box 10 typically includes a base plate 12, side plates 14, 16, and 18, a door frame 20, a top plate 22, and two door panels 24. Side plates 14, 16, 18, and the door frame 20 are connected to the base plate 12 by multiple hinges. Side plates 14, 16, 18, and the door frame 20 can rotate about the hinges between a use position and a folded position. In the use position, side plates 14, 16, 18, and the door frame 20 are typically perpendicular to the base plate 12; in the folded position, side plates 14, 16, 18, and the door frame 20 are typically parallel to the base plate 12.

[0033] Each hinge includes a hinge member 30 and a hinge receiver 32. The hinge member 30 is integrally molded with and extends downward from the lower edge of the side panels 14, 16, 18, and door frame 20, and the hinge receiver 32 is integrally molded with the base plate 12 and extends upward from the base plate 12. Optionally, the positions of the hinge member 30 and the hinge receiver 32 can be interchanged. The hinge receiver 32 is used to pivotally receive the hinge member 30.

[0034] During transportation or storage, side panels 18 and door frame 20 are folded onto the base plate 12, and then side panels 14 and 16 are folded onto side panels 18 and door frame 20. Optionally, side panels 14 and 16 may be folded onto the base plate 12, while side panels 18 and door frame 20 are folded onto side panels 14 and 16.

[0035] Figure 3 This is a schematic diagram of a hinge member 30 on the side plate 14 as viewed from the inner surface of the side plate 14. Other hinge members 30 are the same or substantially similar.

[0036] refer to Figure 3 and Figure 4 The hinge member 30 includes a hinge pin body 36 fixed to the lower edge of the side plate 14 via a base. An opening 38 is formed approximately at the center of the base of the hinge member 30 such that the base forms a pair of supports 40 that connect the hinge pin body 36 to the lower edge of the side plate 14. The hinge pin body 36 includes two cylindrical ends 42 located outside the two supports 40 and a non-cylindrical portion 44 located between the two supports 40.

[0037] The non-cylindrical portion 44 includes a first side 46 formed on a portion of its circumferential surface, a second side 48 adjacent to and extending from the first side 46, a third side 50 adjacent to and extending from the second side 48, a fourth side 52 adjacent to and extending from the third side 50, a fifth side 54 adjacent to and extending from the fourth side 52, and a sixth side 56 adjacent to and extending from the fifth side 54. The sixth side 56 is arranged adjacent to the first side 46, forming a circumferentially continuous distribution of the structure. The first side 46 and the fourth side 52 are circumferential or cylindrical surfaces, with the first side 46 substantially opposite to the fourth side 52. The second side 48 and the fifth side 54 are planar surfaces, with the second side 48 substantially opposite to and parallel to the fifth side 54. The third side 50 and the sixth side 56 are planar surfaces, with the third side 50 substantially opposite to and parallel to the sixth side 56. The cross-sectional configuration of the non-cylindrical portion 44 is defined such that the cross-sectional width W2 of the second side 48 and the cross-sectional width W5 of the fifth side 54 are greater than the cross-sectional width W3 of the third side 50 and the cross-sectional width W6 of the sixth side 56. The dimensions of the paired opposite sides of the non-cylindrical portion 44 (e.g., the second side 48 to the fifth side 54, the third side 50 to the sixth side 56) can be asymmetrically arranged, i.e., different cross-sectional widths are allowed on both sides. The first side 46 and the fourth side 52 are configured as circumferential surfaces to improve the rotational flexibility of the non-cylindrical portion 44 in the hinge receiver 32; however, at least one of the first side 46 and the fourth side 52 can be configured as a plane if reduced flexibility is desired. The improvement of the hinge in this application is that the width between the second side 48 and the fifth side 54 is the minimum width Wmin (or thickness) of the non-cylindrical portion 44, which will be further described below. Since the non-cylindrical portion 44 does not have a uniform outer perimeter, the width between the two sides described in this application is the vertical distance between the second side 48 and the fifth side 54 in the cross-section of the non-cylindrical portion 44, and the vertical distance between two straight lines tangent to and parallel to the outer perimeter of the cross-section of the first side 46 and the fourth side 52.

[0038] Figure 5This is a partial perspective view of the interior of the base plate 12, showing the hinge receiver 32. The hinge receiver 32 includes a pair of opposing, generally concave brackets 58, each bracket 58 including a concave circular surface 60 and two vertical surfaces 62 extending upward on either side of the circular surface 60. A pair of opposing feet 64 are defined between the pair of brackets 58, wherein at least one foot 64 is configured to be slightly deformable, each foot 64 including an inclined surface 66 located at its upper end facing the opposing foot 64, thereby forming a downwardly tapering flared opening between the two feet 64. Each foot 64 also includes an arcuate surface 68 engaging with the lower edge of the inclined surface 66. Optionally, the hinge receiver 32 has a hollowed-out bottom 70. Optionally, one of the feet 64 may be replaced by a wall of the base plate 12, leaving the hinge receiver 32 with only one foot 64.

[0039] like Figure 6 As shown, the side plate 14 and the base plate 12 are in a separated installation position, which is between the use position and the folded position. The angle between the side plate 14 and the base plate 12 is greater than the angle in the folded position but less than the angle in the use position, i.e., greater than 0 degrees and less than 90 degrees. Preferably, the angle is closer to 45 degrees, for example, 30-60 degrees, and the most preferred angle is 45 degrees. In this position, the direction of the minimum dimension Wmin of the non-cylindrical portion 44 is substantially parallel to the base plate 12. In this position, the two cylindrical ends 42 of the hinge member 30 are aligned with the two brackets 58 of the hinge receiver 32. Along the downward direction, the hinge member 30 is inserted into the hinge receiver 32. The third side 50 of the hinge member 30 contacts the inclined surface 66 of one of the shank legs 64, and the fifth side 54 of the hinge member 30 contacts the inclined surface 66 of the other shank leg 64. Under the application of appropriate force, the slightly deformable shank legs 64 thus deflect outward, allowing the hinge pin body 36 to be fully inserted into the hinge receiver 32 from the flared end. At this time, the two cylindrical ends 42 of the hinge member 30 are received in the two brackets 58 of the hinge receiver 32, and the non-cylindrical portion 44 of the hinge member 30 is located between the two shank legs 64 of the two hinge receivers 32.

[0040] Similarly, such as Figure 7As shown, the side plate 14 and the base plate 12 are in the mounted joint position, which is at the same angle as the mounted separation position. The difference is that at this time, the hinge member 30 of the side plate 14 has been inserted into the hinge receiver 32 of the base plate 12. In this position, the hinge member 30 inserted into the hinge receiver 32 can also be disengaged from the hinge receiver 32 in the upward direction. When disengaged, the second side 48 of the hinge member 30 contacts the arcuate surface 68 of one of the shank feet 64, and the sixth side 56 of the hinge member 30 contacts the arcuate surface 68 of the other shank foot 64. Under the application of appropriate force, the slightly deformable shank foot 64 is thus deflected outward, allowing the hinge pin body 36 to disengage from the flared end of the hinge receiver 32.

[0041] As can be seen from the above, the key is that the non-cylindrical portion 44 of the hinge member 30 aligns with the guide opening of the hinge receiver 32 with its minimum dimension Wmin. Therefore, the second side 48 and the fifth side 54, which define the minimum dimension Wmin, are the key surfaces on which the hinge member 30 can be inserted into or detached from the hinge receiver 32. The third side 50 and the sixth side 56 of the hinge member 30 are equivalent to guide surfaces, which are only used to guide the non-cylindrical portion 44 to align with the guide opening with its minimum dimension Wmin. Therefore, in other embodiments, the non-cylindrical portion 44 may also be without the third side 50 and the sixth side 56. In this case, the second side 48 is adjacent to the fourth side 52, and the fifth side 54 is adjacent to the first side 46. When the hinge member 30 is inserted into or detached from the hinge receiver 32, the second side 48 and the fifth side 54 respectively contact the inclined surface 66 or the arcuate surface 68 of the handle 64.

[0042] like Figure 8 As shown, in the usage position, the first side 46 of the hinge member 30 contacts the arcuate surface 68 of one of the handles 64, and the fourth side 52 of the hinge member 30 contacts the arcuate surface 68 of the other handle 64. Since the width between the first side 46 and the fourth side 52 is greater than the width between the second side 48 and the fifth side 54, and the width between the first side 46 and the fourth side 52 is configured such that even if the handle 64 deflects outward, it is insufficient to disengage the hinge member 30 from the hinge receiver 32, therefore each hinge member 30 is locked in the hinge receiver 32. Similarly, as... Figure 9As shown, in the folded position, the first side 46 of the hinge member 30 contacts the arcuate surface 68 of one of the handle legs 64, and the second side 48 of the hinge member 30 contacts the arcuate surface 68 of the other handle leg 64. Since the maximum width extending between the first side 46 and the second side 48 is also greater than the width between the second side 48 and the fifth side 54, and the maximum width between the first side 46 and the second side 48 is configured such that even if the handle leg 64 deflects outward, it is insufficient to cause the hinge member 30 to disengage from the hinge receiver 32, each hinge member 30 is also locked in the hinge receiver 32. Through the above construction, it is ensured that the hinge member 30 cannot disengage from the hinge receiver 32 when the storage box 10 is in the use position and the folded position, ensuring the user experience, and at the same time preventing the hinge member 30 from disengaging from the hinge receiver 32 due to vibration during transportation, which would cause accumulation and damage.

[0043] like Figure 3 and Figure 8 As shown, the abutment 69 is fixed to the lower edge of the side panel 14 and located within the opening 38. When the side panel 14 is rotated to the use position, the abutment 69 abuts against the inner surface of the base plate 12, preventing the side panel 14 from rotating further in the direction opposite to the folded position. Side panels 16, 18, and the door frame 20 have the same or similar abutments 69.

[0044] like Figure 10-13 As shown, the door panel frame 20 includes two side straight frame members 71 extending along the height, and an upper straight frame member 74 and a lower straight frame member 76 extending along the length direction located between the two side straight frame members 71. Each door panel 24 includes a pivot side 78 and an opposing free side 80. The pivot sides 78 of the two door panels 24 are respectively adjacent to the two side straight frame members 71 and engaged between the upper straight frame member 74 and the lower straight frame member 76 (or may be engaged on the side straight frame members 71). The two door panels 24 are rotatable about their respective pivot sides 78.

[0045] The door frame 20 defines an opening 82. When the two door panels 24 rotate about the pivot side 78 until the two free sides 80 are opposite each other and located within the opening 82, the two door panels 24 close the opening 82. The upper straight frame member 74 of the door frame 20 includes two downwardly extending blocking members 88 that can prevent the two door panels 24 from rotating further into the storage box 10. The corresponding two door panels 24 have relief recesses 90 corresponding to the positions of the blocking members 88, so that the surfaces of the door panels 24 and the door frame 20 remain flush when the opening 82 is closed.

[0046] The door frame 20 also includes an upper latch 92, which is substantially located in the middle of the upper straight frame member 74. The upper latch 92 includes a switch 94 that slides along a sliding groove 96 on the upper straight frame member 74. The sliding groove 96 extends in the same direction as the length of the upper straight frame member 74 (i.e., the length of the door frame 20). Two pins 98 are integrally molded with the lower edge of the switch 94 and extend downward from the lower edge (i.e., vertically into the opening 82) to be disposed in the opening 82, so that the pins 98 can slide along the length of the upper straight frame member 74 (i.e., the length of the door frame 20) by sliding the switch 94.

[0047] Each door panel 24 includes an upper straight edge member 100 facing the upper straight frame member 74 of the door panel frame 20 when the opening 82 is closed. An upper locking groove 102 is provided on the upper straight edge member 100 at a position corresponding to the pin 98 of the upper latch 92. The upper locking groove 102 has an open top corresponding to the pin 98. The upper locking groove 102 includes a first groove 104 extending along the length direction of the upper straight edge member 100 (i.e., the length direction of the door panel 24) and a second groove 106 extending along the width direction of the upper straight edge member 100 (i.e., the width or thickness direction of the door panel 24). The first groove 104 of the upper locking grooves 102 of the two door panels 24 extends from their respective second grooves 106 in the same direction, so the upper locking grooves 102 on the two door panels 24 are not mirror-symmetrical. One end of the first groove 104 and the proximal end of the second groove 106 communicate to form a generally L-shaped upper locking groove 102. The distal end of the first slot 104 is closed, and the distal end of the second slot 106 faces into the storage box 10 and has a slot 108 corresponding to the pin 98. The pin 98 can slide to align with the slot 108 and enter the locking slot 102 from the slot 108 (the length of the pin 98 extending downward from the switch 94 makes it only possible to enter or leave the locking slot 102 through the slot 108, and the open top of the locking slot 102 allows the pin 98 to move within the locking slot 102). The locking slot 102 and the bolt 98 are configured such that when the bolt 98 is aligned with the slot 108, as the door panel 24 rotates toward the bolt 98, the bolt 98 enters the locking slot 102 from the slot 108, and when the door panel 24 is fully closed, the bolt 98 is located at the junction of the proximal ends of the first slot 104 and the second slot 106, in which position the slide switch 94 can move the bolt 98 toward the distal end of the first slot 104 along the extension direction of the first slot 104. When the bolt 98 is located in the first slot 104 and is not aligned with the slot 108, the door panel 24 will be prevented from opening.

[0048] When the door panel 24 is to be opened, the latch 98 is first moved along the first groove 104 to the connection point of the near end of the first groove 104 and the second groove 106 by means of the switch 94. Since the latch 98 is aligned with the groove 108 in this position, when the door panel 24 is rotated outward away from the latch 98, the latch 98 will exit the locking groove 102 from the groove 108.

[0049] A lower latch 110 with the same structure as the upper latch 92 can also be provided on the lower straight frame member 76 of the door panel frame 20. Correspondingly, a lower locking groove (not shown in the figure) is provided on the lower straight edge member 101 of the door panel 24. As needed, only the upper latch (with corresponding upper locking groove) or the lower latch (with corresponding lower locking groove) can be provided. A blocking member 112 with the same structure as the blocking member 88 can also be provided on the lower straight frame member 76. Correspondingly, an avoidance recess (not shown in the figure) is provided on the door panel 24 at the position corresponding to the blocking member 112. As needed, only the blocking member can be provided on the upper straight frame member 74 or the lower straight frame member 76. It should be understood that in other embodiments, there may be only one door panel 24, in which case the number of corresponding latches 98 may be one. With a single door panel, the door panel can be rotatably engaged on one side of the door panel frame adjacent to the upper straight frame member, lower straight frame member, or side straight frame member. The position of the upper latch 92 is also adjusted accordingly, typically opposite the rotating side of the door panel, and the lock groove is correspondingly provided on the upper / lower straight edge member in the length direction or the side straight edge member in the height direction of the door panel. It should be understood that the door panel frame 20 may be an independent component or may be jointly formed by other components such as side panels, bottom panels, and top panels. It should be understood that the upper latch 92 may be provided on the door panel frame 20 or on the top panel 22. It should be understood that there may be two latches, each latch controlling the sliding of one latch.
