[0068] See Figure 2 , Figures 4 to 8 This utility model provides a flip-up caster assembly 110. The flip-up caster assembly 110 includes a first fixing member 111, a guide member 112, a first sliding member 114, and a caster member 115. The first fixing member 111 is adapted to be fixed to the base frame 101 of a container 100. The guide member 112 is connected to the lower part of the first fixing member 111 in the vertical direction D3. The first sliding member 114 is located below the first fixing member 111 in the vertical direction D3. The first sliding member 114 is movably connected to the guide member 112 in a retracted position and an extended position along a first horizontal direction D1. In the retracted position, the first sliding member 114 is limited between the first fixing member 111 and the guide member 112 along the vertical direction D3 of the first fixing member 111. In the extended position, the first sliding member 114 is pivotally connected to the guide member 112 about a rotation axis AX between a use position and a folded position. Any two of the rotation axis AX, the vertical direction D3, and the first horizontal direction D1 are perpendicular. The caster component 115 is located below the first fixed component 111 in the vertical direction D3. The caster component 115 is connected to the first sliding component 114.
[0069] When the first sliding member 114 is in the use position, the caster member 115 is located on the side of the first sliding member 114 away from the first fixed member 111 along the vertical direction D3, and the caster member 115 can move along the first horizontal direction D1 with the first sliding member 114.
[0070] When the first sliding member 114 is in the folded position, the caster member 115 is located on the side of the first sliding member 114 away from the first fixed member 111 along the first horizontal direction D1, and the caster member 115 cannot move towards the retracted position along the first horizontal direction D1.
[0071] According to an embodiment of the present invention, the flip-up caster assembly 110, when applied to a container 100, allows the first sliding member 114 to be placed in the retracted position, enabling the caster assembly 115 to support the container 100 and facilitating its movement. This allows the container 100 to be used in scenarios where it is unsuitable to move it using construction machinery. When applied to the container 100, placing the first sliding member 114 in the extended position and rotating it to the folded position allows the container 100 to stably carry goods.
[0072] See Figures 5 to 8In some embodiments, the flip-up caster assembly 110 includes a pair of guide members 112. The pair of first guide members 112 are spaced apart and arranged opposite each other along a first horizontal direction D1. A groove 113 extending along the first horizontal direction D1 is formed between the guide members 112 and the first fixing member 111. The flip-up caster assembly 110 also includes a second sliding member 121. The second sliding member 121 is movably connected to the groove 113 along the first horizontal direction D1. A first sliding member 114 is pivotally connected to the second sliding member 121 about a rotation axis AX. The first sliding member 114 in the retracted position is within the groove 113. The first sliding member 114 in the extended position disengages from the groove 113 to be able to rotate about the rotation axis AX between a use position and a folded position. The first sliding member 114 in the use position and the second sliding member 121 are arranged sequentially along the first horizontal direction D1. The first sliding member 114 in the folded position intersects with the second sliding member 121. During the movement of the first sliding member 114 along the first horizontal direction D1, the second sliding member 121 remains within the groove 113. The second sliding member 121 helps prevent the first sliding member 114 from completely disengaging from the guide member 112, and facilitates the movement of the first sliding member 114 from the folded position to the used position to the retracted position.
[0073] See Figures 5 to 7 Furthermore, the guide member 112 includes a positioning hole 112a. The positioning hole 112a extends along a first horizontal direction D1 and communicates with the slide groove 113. The guide member 112 includes a first limiting wall 112a1 corresponding to one end of the positioning hole 112a along the first horizontal direction D1. The flip-up caster assembly 110 also includes a first connecting member 118. The first connecting member 118 passes through the positioning hole 112a and is connected to the second sliding member 121. The first sliding member 114 is in the extended position when the first connecting member 118 abuts against the first limiting wall 112a1. The first connecting member 118 can move in the positioning hole 112a along the first horizontal direction D1 with the second sliding member 121. Through the abutting engagement of the first limiting wall 112a1 and the first connecting member 118, the first sliding member 114 can be prevented from continuing to move after it has moved to the extended position, thereby preventing the first sliding member 114 and the second sliding member 121 from disengaging from the guide member 112.
[0074] Continue reading Figures 5 to 7Optionally, the guide member 112 includes a second limiting wall 112a2 corresponding to the other end of the positioning hole 112a along the first horizontal direction D1. The first sliding member 114 is in the retracted position when the first connector 118 abuts against the second limiting wall 112a2. In the installed state installed to the container 100, the second limiting wall 112a2 is further away from the outside of the container 100 in the horizontal direction than the first limiting wall 112a1. By providing the second limiting wall 112a2 to cooperate with the first connector 118, the first sliding member 114 can be limited in the retracted position.
[0075] In other examples, the guide member 112 may not have a second limiting wall 112a2. That is, the positioning hole 112a is an open hole. In the installed state of the container 100, the positioning hole 112a can be closed by the base frame 101 of the container 100. This means that the second limiting wall 112a2 is provided on the base frame 101 of the container 100.
[0076] Optionally, the first connector 118 is a fastener such as a bolt or pin. The positioning hole 112a is an oblong hole.
[0077] See Figure 6 and Figure 7 Furthermore, the first sliding member 114 includes a first connecting portion 114a. The first connecting portion 114a aligns with the positioning hole 112a when the first sliding member 114 is in the retracted position. The flip-up caster assembly 110 also includes a second connecting member 119. The second connecting member 119 is detachably connected to the positioning hole 112a and the first connecting portion 114a. The connection of the second connecting member 119 to the positioning hole 112a and the first connecting portion 114a facilitates securing the first sliding member 114 to the guide member 112, thereby preventing movement of the first sliding member 114 and holding it in the retracted position. By removing the second connecting member 119 from the positioning hole 112a and the first connecting portion 114a, movement of the first sliding member 114 in the first horizontal direction D1 is possible.
[0078] Optionally, the second connector 119 is a fastener such as a bolt or pin. If the second connector 119 is a bolt, the first connecting portion 114a is a threaded hole.
[0079] See Figure 2 , Figure 4 ,as well as Figure 7Furthermore, the tilting caster assembly 110 also includes a second fixing member 122 and a third connecting member 123. The second fixing member 122 is adapted to be fixed to the side wall 103 of the container 100. The second fixing member 122 includes a second connecting portion 122a. The caster assembly includes a caster mounting member 116 and a caster 117. The caster mounting member 116 is fixed to a first sliding member 114. The caster mounting member 116 includes a third connecting portion 116a. The third connecting member 123 is adapted to be detachably connected to the second connecting portion 122a and the third connecting portion 116a. By providing the second fixing member, it is convenient to fix the first sliding member 114, which is tilted to the folded position, to the second fixing member 122 when the container 100 is in use, thereby fixing the caster assembly 115 to the side wall 103 of the container 100 and preventing the caster assembly 115 from tilting to the use position during the transport of the container 100.
[0080] Optionally, the third connecting member 123 can be a fastener such as a bolt or pin. If the third connecting member 123 is a bolt, the second connecting portion 122a is a threaded hole. The second fixing member 122 can be a metal block or a thickened metal plate. The caster mounting member 116 can be a metal plate. The caster 117 can be a swivel wheel.
[0081] See Figures 4 to 7 Furthermore, the first sliding member 114 and the second sliding member 121 are located between a pair of guide members 112 along a second horizontal direction D2 parallel to the axis of rotation AX. This also limits the movement of the first sliding member 114, the second sliding member 121, and the caster member 115 along the second horizontal direction D2.
[0082] Optionally, the first sliding member 114 is a slider. The second sliding member 121 can be a strip-shaped or rod-shaped structure.
[0083] See Figures 5 to 7 Optionally, the first fixing member 111 is constructed as a plate. The guide member 112 includes a first guide 112c and a second guide. The first guide 112c is fixed to the lower part of the first fixing member 111 along the vertical direction D3. The second guide is connected to the end of the first guide 112c along the vertical direction D3 away from the first fixing member 111. A groove 113 is formed between the first fixing member 111, the first guide 112c, and the second guide. The groove 113 is, for example, a U-shaped groove. With both the first sliding member 114 and the second sliding member 121 located within the groove 113, the second guide 112 and the first fixing member 111 together limit the first sliding member 114 and the second sliding member 121 in the vertical direction D3, and in particular, the load of the container 100 can be carried through the cooperation of the first sliding member 114 and the first fixing member 111.
[0084] In other embodiments not shown, one end of the first fixing member 111 in the first horizontal direction D1 is provided with a clearance notch suitable for accommodating the first sliding member 114. When the first sliding member 114 is in the extended position, the rotation axis AX is aligned with the clearance notch in the vertical direction D3 to allow the first sliding member 114 to rotate between the use position and the folded position. The first sliding member 114 in the folded position is in the clearance notch. By providing a clearance notch in the first fixing member 111, the first sliding member 114 can rotate to the folded position when it slides to the extended position without the second sliding member 121.
[0085] Optionally, the first sliding member 114 can be connected to the positioning hole 112a by fasteners such as bolts. In the installed state where the tilting caster assembly 110 is installed on the container 100, a portion of the positioning hole 112a is located outside the horizontal direction of the container 100, so that when the first sliding member 114 moves to the end of the positioning hole 112a and is in the extended position, it can be tilted upward to the folded position.
[0086] See Figures 1 to 4 Another embodiment of the present invention provides a container 100. The container 100 includes a base frame 101, a pair of side walls 103, corner brackets 104, and the aforementioned flip-up caster assembly 110. The base frame 101 includes a pair of bottom side beams 102. Each bottom side beam 102 has a pair of mounting slots 102a at its lower part. The pair of mounting slots 102a are located at both ends of the bottom side beam 102. The pair of side walls 103 are connected to the upper part of the bottom side beams 102. The corner brackets 104 are connected to the corners of the base frame 101. There are multiple flip-up caster assemblies 110. The multiple flip-up caster assemblies 110 are respectively connected to the bottom side beams 102 at each mounting slot 102a. The flip-up caster assembly 110 includes a second fixing member. The second fixing member is fixed to the side wall 103 at the mounting slot 102a. When the first sliding member 114 is in the retracted position, the caster member 115 protrudes from the lower surface of the corner bracket 104. When the first sliding member 114 is in the folded position, the caster member 115 is higher than the lower surface of the bottom corner member 104. The caster member 115 is detachably connected to the second fixing member.
[0087] In container 100, the first horizontal direction D1 is the width direction of container 100, the second horizontal direction D2 is the length direction of container 100, and the vertical direction D3 is the height direction of container 100.
[0088] According to the embodiments of the present invention, the container 100, by applying the above-mentioned tilting caster assembly 110, enables the container 100 to have flexible mobility in some application scenarios where it is not convenient to move it with engineering machinery, and enables the container 100 to have stable load-bearing capacity in application scenarios where it carries goods and transports or stores goods over long distances, thereby achieving the effect that moving the container 100 without specific engineering machinery does not affect its stability when carrying and placing goods.
