Hinge device and foldable container having the same

Abstract

The present application provides a hinge device and a foldable container having the same. The hinge device includes a fixed hinge, a movable hinge, a tilting pedal, and a locking mechanism. The fixed hinge includes a pair of wall panels arranged vertically. The tilting pedal is pivotally connected to a bracket and / or the fixed hinge. The locking mechanism is pivotally connected to the fixed hinge between a locked position and a released position. The locking mechanism includes a bracket, a bracket pin, and a locking block. The bracket includes a blocking member. The bracket pin is provided near the outer end to the bracket to pivot the bracket to the fixed hinge. The locking block is movably retained by the bracket. When the movable hinge pivots relative to the fixed hinge from a horizontal position to a vertical position, it pushes the locking block in the locked position, causing the movable hinge in the vertical position to be at least partially located below the locking block in the locked position. When the movable hinge pivots from the vertical position to the horizontal position, the locking block blocks movement of the movable hinge. The locking mechanism can be driven from the locked position to the released position by operating the tilting pedal and the blocking member.

Description

Technical Field

[0001] The present application generally relates to the technical field of containers, and more particularly to a hinge device and a foldable container having the same. Background Art

[0002] In current foldable containers, the foldable end frames are hinged to the base frame via a hinge device. After the end frames are erected, the pins of the hinge device need to be manually operated to lock the end frames. The hinge device generally includes a movable hinge fixed to the lower end of the end frame and fixed hinges fixed to both sides of the base frame end. The movable hinge is hinged to the fixed hinge via a pin shaft, so that the end frame of the container can be flipped between a folded position folded on the base frame and an open position along the vertical direction. When the end frame of the container is in the open position, the operator inserts the pin from the inside of the fixed hinge to the outside into the corresponding holes or notches of the movable hinge and the fixed hinge, so that the movable hinge is fixed to the fixed hinge, so that the end frame cannot be flipped from the open position to the folded position under the action of external force. When the end frame of the container needs to be flipped from the open position to the folded position, the operator needs to pull out the pin in advance.

[0003] In addition, in current foldable containers, the pivot axis of the hinge assembly (e.g., the tilting pin) is positioned away from the end frame of the container, allowing the end frame to stand in the open position, making it easier for the operator to operate the latch without requiring other operators to hold the end frame. However, in some cases, the operator may forget to lock the latch into the correct position. Furthermore, since the latch is within the outer contour plane of the container in both the open and locked states, it is difficult for the operator to detect it. If the latch of the hinge assembly is not locked into the correct position, there will be a significant safety hazard to the on-site personnel, the container, the cargo, and the equipment used to operate the container when the operator is operating the foldable container.

[0004] In order to solve the above problems, a patent application with publication number CN110406820A discloses a hinge device. Although it can solve the above problems, it still has the following shortcomings: (1) In order to ensure the tight locking between the movable hinge and the fixed hinge, the gap between the locking block and the fixed hinge and the movable hinge is small when locking. In order to ensure that the locking block can operate smoothly when it flips around the bracket pin, the locking block needs to be movably clamped on the bracket. While flipping around the bracket pin, the locking block can also flip around itself; however, in order to move the locking mechanism to the release position, the locking mechanism is provided with a pull ring, which is directly pivoted on the locking block. When the pull ring is manually pulled up for operation, the locking block will not be able to flip around itself, and the locking block will be stuck. Then, the opening operation of the locking block will be greatly affected or even impossible to operate; (2) After the locking mechanism moves to the release position, it will remain in the release position and will not return to its original position. After the operator performs the folding or opening operation of the end frame, it is necessary to release the locking state of the locking mechanism in the release position and allow the locking mechanism to move to the locking position under the action of its own weight. The mechanism for maintaining the locking mechanism in the released position complicates the structure of the entire hinge device, making it inconvenient to produce and use; (3) the bracket includes a side plate and an end plate connected to the side plate, and the contact surface between the side plate and the end plate and the locking block is an outwardly protruding arc surface, thereby realizing the movable clamping between the locking block and the bracket, which is equivalent to the locking block receiving groove being processed by the bracket and the end plate. The processing cost and difficulty are high, and there are many steps.

[0005] Therefore, it is necessary to provide a hinge device and a foldable container having the same to at least partially solve the above problems. Summary of the Invention

[0109] Hereinafter, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings. These drawings illustrate representative embodiments of the present application and do not limit the present application.

[0110] The present application provides a hinge device 100 and a foldable container having the hinge device 100. The foldable container mainly includes a base frame (not shown) arranged in a horizontal direction and end frames (not shown) arranged at both ends of the base frame, and the end frames can move between a folded position folded on the base frame and an open position perpendicular to the base frame. The hinge device 100 is used to pivotally connect the end frames to the base frame. The base frame is roughly constructed as a rectangular frame structure, and the hinge devices 100 are arranged on both sides of the end of the base frame and at both ends of the end frames. In order to facilitate understanding of the solution, first combine Figures 1 to 14 The structure of the hinge device 100 will be described in detail.

[0111] See also Figures 1 to 14 As shown, the hinge device 100 mainly includes a fixed hinge 110, a movable hinge 120, a flip pedal 160 and a locking mechanism 140. The fixed hinge 110 is used to be fixedly connected to the bottom frame (not shown), and the movable hinge 120 is used to be fixedly connected to the end frame (not shown).

[0112] The fixed hinge 110 includes a pair of wall panels arranged in a vertical direction D1. The movable hinge 120 is provided between the pair of wall panels of the fixed hinge 110. The movable hinge 120 is connected to the fixed hinge 110 and can pivot relative to the fixed hinge 110 between a horizontal position and a vertical position.

[0113] Specifically, if Figures 1 to 3 As shown, the fixed hinge 110 includes an outer wall panel 111 and an inner wall panel 114 disposed opposite the outer wall panel 111 , the outer wall panel 111 and the inner wall panel 114 being disposed along a vertical direction D1 and parallel to each other.

[0114] The fixed hinge 110 and the movable hinge 120 are pivotally connected via a pivot shaft 130, so that the movable hinge 120 can move between a horizontal position and a vertical position. The pivot shaft 130 can be roughly configured as a circular columnar structure. Figure 4 and Figure 5 As shown, the movable hinge 120 may be provided with an inner pin shaft hole 123, and the outer wall panel 111 and the inner wall panel 114 may be provided with outer pin shaft holes 115. The pivot shaft 130 extends through the inner pin shaft hole 123 and the outer pin shaft hole 115 to pivotally connect the movable hinge 120 to the fixed hinge 110. In this embodiment, one end of the movable hinge 120 is provided on the inner side of the outer wall panel 111 and the inner wall panel 114, and the other end of the movable hinge 120 extends beyond the outer wall panel 111 and the inner wall panel 114 for connection to the end frame.

[0115] The locking mechanism 140 is capable of locking the living hinge 120 in a locked position (see Figure 1 ) and a release position for releasing the movable hinge 120 and is pivotally connected to the fixed hinge 110. Specifically, see Figures 6 to 8 The locking mechanism 140 mainly includes a bracket 141, a locking block 143, and a bracket pin 144. The bracket 141 is pivotally connected to the fixed hinge 110. The bracket 141 includes an outer plate 145 and an inner plate 154 arranged along the vertical direction D1, a connecting member 146 connecting the outer plate 145 and the inner plate 154, and a blocking member 155 arranged along the horizontal direction D2.

[0116] See you later Figures 1 to 3The outer side plate 145 of the bracket 141 is disposed between the outer wall panel 111 and the movable hinge 120, and the inner side plate 154 is disposed between the inner wall panel 114 and the movable hinge 120. The bracket pin 144 is disposed at the bottom of the outer end of the bracket 141 along the transverse direction D2 and pivotally connects the bracket 141 to the outer wall panel 111 and the inner wall panel 114 of the fixed hinge 110. The blocking member 155 is disposed on at least one of the outer side plate 145 and the inner side plate 154.

[0117] Combine Figures 1 to 3 The locking block 143 is movably engaged with the bracket 141. The flip pedal 160 of the hinge device 100 is pivotally connected to at least one of the bracket 141 and the fixed hinge 110, so that the flip pedal 160 can pivot relative to the bracket 141. The flip pedal 160 is configured to rotate to engage with the blocking member 155, thereby driving the locking mechanism 140 from the locked position to the released position, thereby allowing the movable hinge 120 to pivot toward the horizontal position.

[0118] During the process of the movable hinge 120 pivoting from the horizontal position to the vertical position, the movable hinge 120 can push the locking block 143 in the locking position. As a result, the movable hinge 120 in the vertical position is at least partially located below the locking block 143 in the locking position, thereby locking the movable hinge 120 in the vertical position (the locking block 143 in the locking position blocks the movable hinge 120 from moving from the vertical position to the horizontal position).

[0119] When the movable hinge 120 needs to be pivoted from the vertical position to the horizontal position, the flip pedal 160 is operated to rotate relative to the bracket 141 until the flip pedal 160 engages with the blocking member 155 on the bracket 141. The flip pedal 160 is then continued to rotate, causing the flip pedal 160 to rotate the bracket 141 around the axis of the bracket pin 144, thereby changing the position of the locking block 143 and allowing the locking block 143 to separate from the movable hinge 120. At this point, the movable hinge 120 can be rotated from the vertical position to the horizontal position.

[0120] It should be noted that, in this document, the "horizontal position" of the movable hinge 120 corresponds to the "folded position" of the end frame, and the "vertical position" of the movable hinge 120 corresponds to the "open position" of the end frame. In other words, when the movable hinge 120 is in the horizontal position, the movable hinge 120 is generally arranged in the horizontal direction, and when the movable hinge 120 is in the vertical position, the movable hinge 120 is generally arranged in the vertical direction.

[0121] When the locking mechanism 140 is in the locked position (see Figure 1), the position of the living hinge 120 is locked, so that the end frame is locked in the open position. When the locking mechanism 140 is in the release position, the lock on the position of the living hinge 120 can be released, so that the end frame can be pivoted from the open position to the folded position (see Figure 3 ).

[0122] The hinge device 100 according to the present application has a simple structure and is easy to manufacture and use. An operator can operate the flip pedal 160 by stepping on it, thereby moving the locking mechanism 140 from the locked position to the released position. Simultaneously, the operator can manually flip the end frame to move the movable hinge 120 from a vertical position to a horizontal position, and vice versa. This allows a single operator to independently complete both the folding (pivoting the end frame to the folded position) and assembly (pivoting the end frame to the open position) operations of the foldable container, providing ease of use and labor savings.

[0123] See also Figure 5 , the movable hinge 120 is provided with a protrusion 121. The protrusion 121 is provided at the outer end of the movable hinge 120, and the protrusion 121 may include an upward supporting surface 122. It should be noted that the directional terms "outside" and "upper" here are used as a reference when the movable hinge 120 is in a vertical position. When the movable hinge 120 is pivoted from a horizontal position to a vertical position, the protrusion 121 can abut against the locking block 143 and apply a thrust to the locking block 143, so that the locking block 143 moves outward and leaves the locking position. When the movable hinge 120 is in a vertical position, the supporting surface 122 is provided below the locking block 143 and can abut against the locking block 143, so that the locking block 143 can be clamped between the supporting surface 122 of the protrusion 121 and the fixed hinge 110 in the vertical direction.

[0124] The protrusion 121 may also be provided with abutment surface 124. The support surface 122 is tilted relative to the abutment surface 124 (see FIG. Figure 5 In this embodiment, when the movable hinge 120 is in the vertical position, the abutment surface 124 is arranged to be inclined upward toward the outer end of the hinge device 100. When the movable hinge 120 is pivoted from the horizontal position to the vertical position, the abutment surface 124 can abut the locking block 143 and push the locking block 143 away from the locked position.

[0125] See you later Figures 1 to 3 The fixed hinge 110 may further include a bottom corner piece 116 provided at the lower portion of the exterior wall panel 111 and a connecting corner piece 117 provided at the upper portion of the exterior wall panel 111. The bottom corner piece 116 and the connecting corner piece 117 are both provided at the outer ends of the exterior wall panel 111 and the interior wall panel 114. Figure 4The outer end surface F1 of the bottom corner piece 116 extends beyond the outer end surfaces of the exterior wall panel 111 and the interior wall panel 114 (the outer end surfaces of the exterior wall panel 111 and the interior wall panel 114 are the end surfaces away from the movable hinge 120). The fixed hinge 110 also includes a clamping block 112. The clamping block 112 is arranged at the outer ends of the exterior wall panel 111 and the interior wall panel 114 along the transverse direction D2 and is mounted to the exterior wall panel 111 and the interior wall panel 114. The clamping block 112 is provided with a locking surface 113, which is the lower surface of the clamping block 112. When the movable hinge 120 is in the vertical position, the locking block 143 can be clamped between the locking surface 113 and the support surface 122 in the vertical direction.

[0126] In this embodiment, the connecting member 146 connects the outer plate 145 and the inner plate 154 into a whole, and the blocking member 155 is supported and connected between the outer plate 145 and the inner plate 154. Figure 6 As shown, the connecting member 146 of the bracket 141 is arranged at the outer end of the locking block 143 along the horizontal direction D2 and is arranged above the bracket pin 144. The blocking member 155 is located above the bracket pin 144 and below the connecting member 146. The outer side plate 145 and the inner side plate 154 are pivotally mounted to the outer wall plate 111 and the inner wall plate 114 via the bracket pin 144 (see Figures 1 to 3 The bottom of the outer side plate 145 and the inner side plate 154 are provided with side plate pin holes 153, and the outer wall plate 111 and the inner wall plate 114 of the fixed hinge 110 are correspondingly provided with wall plate pin holes 118 (see Figure 4 The bracket pin 144 extends through the side panel pin hole 153 and the wall panel pin hole 118 to pivotally connect the bracket 141 to the fixed hinge 110.

[0127] Preferably, in this embodiment, the bracket pin 144 is provided at the outer end of the outer wall panel 111 and the inner wall panel 114 (the end away from the movable hinge 120), and the pivot shaft 130 is provided at the inner end of the outer wall panel 111. The center of gravity of the locking mechanism 140 is located on the side of the vertical plane where the axis of the bracket pin 144 is located, close to the pivot shaft 130 (see FIG. Figure 10 ), so the locking mechanism 140 can automatically return to the locked position under the action of its own gravity.

[0128] Continue to refer to Figure 6The locking block 143 is movably retained by the outer plate 145 and the inner plate 154. Specifically, the outer plate 145 and the inner plate 154 are provided with an upwardly opening receiving groove 147, in which the locking block 143 is movably retained. The connecting member 146 is disposed at the outer end of the locking block 143. In this embodiment, the receiving groove 147 is entirely provided on the side plate 145. Therefore, the receiving groove 147 can be manufactured by simply cutting the material in an annular shape, which simplifies the manufacturing process, reduces costs, and improves precision control. The upper area of ​​the inner surface of the receiving groove 147 is configured as an outwardly protruding arcuate surface 148. The arcuate surfaces 148 are disposed on opposite sides of the locking block 143 and contact the locking block 143. This reduces the contact area between the receiving groove 147 and the locking block 143 and ensures that the locking block 143 can rotate around the bracket pin 144 while also rotating around itself, thereby realizing the switching operation of the locking mechanism 140 between the released position and the locked position.

[0129] Combine Figure 6 and Figure 7 The lower area of ​​the inner surface of the receiving groove 147 is constructed as an arc-shaped transition surface 149. This transition surface 149 can be located near the outer end of the side plate 145. A relief notch 152 is provided on the locking block 143 at the location corresponding to the transition surface 149. The portion of the locking block 143 between the outer side plate 145 and the inner side plate 154 does not have the relief notch 152. Therefore, the relief notches 152 are provided on both sides of the outer end of the locking block 143, allowing the locking block 143 to rotate in the receiving groove 147 using the arc-shaped surface 148 as a fulcrum, while the side plate 145 can limit the locking block 143 in the lateral direction D2. The transition surface 149 can be rounded or oblique.

[0130] A limiting member 151 is provided on the outer end surface of the locking block 143 . The limiting member 151 is provided below the connecting member 146 and can abut against the connecting member 146 to limit the locking block 143 from upwardly separating from the receiving groove 147 .

[0131] refer to Figures 8 to 10In this embodiment, the flip pedal 160 includes an operating portion 161 and a matching portion 162 that are connected to each other. The matching portion 162 is located between the outer plate 145 and the inner plate 154, and the operating portion 161 is located at the outer end of the bracket 141. The operating portion 161 and the matching portion 162 are respectively located on both sides of the bracket pin 144, and a connecting hole 163 for connecting to the bracket pin 144 is provided at the connection position between the operating portion 161 and the matching portion 162. In other words, in this embodiment, the pivot axis of the flip pedal 160 is the same as the pivot axis of the bracket 141. The operating portion 161, the matching portion 162 and the bracket pin 144 constitute a lever structure. By operating the operating portion 161, the matching portion 162 on the other side of the bracket pin 144 is driven to rotate, so that the matching portion 162 contacts the blocking member 155, thereby realizing the transmission of force to the blocking member 155.

[0132] The flip pedal 160 can pivot about the axis of the bracket pin 144 between a stowed position and a flip position.

[0133] In the storage position, the engaging portion 162 does not contact the blocking member 155, and the operating portion 161 does not extend beyond the vertical plane of the outer end of the fixed hinge 110. At this time, the locking mechanism 140 is in the locking position.

[0134] In the flip position, the engaging portion 162 abuts the blocking member 155, and the operating portion 161 extends beyond the vertical plane of the outer end of the fixed hinge 110. When the flip pedal 160 rotates about the axis of the bracket pin 144 toward the outer end of the bracket 141, it drives the bracket 141 to rotate synchronously. At this point, the flip pedal 160 drives the locking mechanism 140 toward the released position. It will be understood that in this embodiment, the vertical plane of the outer end of the fixed hinge 110 specifically refers to the vertical plane of the end of the fixed hinge 110 away from the movable hinge 120. The fact that the flip pedal 160 extends beyond this plane facilitates user operation.

[0135] In this embodiment, the flip pedal 160 and the blocking member 155 are both located between a pair of side plates of the bracket 141, and the operating portion 161 is connected to the matching portion 162 to form a ring (see FIG. Figure 8 ), facilitating user operation. In other embodiments not disclosed in this application, those skilled in the art may flexibly adjust the position, shape, and size of the operating portion 161, the mating portion 162, and the blocking member 155 according to actual circumstances. For example, the lever arm on the operating portion 161 side (specifically, the distance between the operating portion and the bracket pin 144) may be set to be larger than the distance between the blocking member 155 and the bracket pin 144 to achieve a more labor-saving and easier operation. For example, the flip pedal and the blocking member may be positioned between the bracket 141 and the fixed hinge 110.

[0136] In this embodiment, the fixed hinge 110 further includes a bottom corner piece 116, which is provided to the lower portion of the outer side panel 145 and the inner side panel 154 (see FIG. Figure 4 ). See Figure 8 The mating portion 162 includes a first mating surface 162a for mating with the blocking member 155 and a second mating surface 162b for mating with the bottom corner piece 116. The blocking member 155 has a blocking surface 155a for contacting the first mating surface 162a.

[0137] When the flip pedal 160 is in the storage position, Figure 9 As shown, the flip pedal 160 is now rotated until the mating portion 162 abuts the top surface F2 of the floor fitting 116, and the operating portion 161 does not extend beyond the outer end surface F1 of the floor fitting 116 (the operating portion 161 does not extend beyond the vertical plane of the outer end of the fixed hinge 110). Specifically, the flip pedal 160 is now entirely located inside the outer end surface F1 of the floor fitting 116, and the flip pedal 160 is not in use. In other words, when in the stowed position, the flip pedal 160 does not extend beyond the outer contour of the foldable container. The placement of the flip pedal 160 does not affect the size of the foldable container and effectively protects the flip pedal 160.

[0138] When the flip pedal 160 is in the flip position, see Figure 10 At this time, the matching portion 162 of the flip pedal 160 abuts against the blocking member 155, and the operating portion 161 of the flip pedal 160 is located outside the outer end surface F1 of the bottom corner piece 116 (the operating portion 161 is beyond the vertical plane of the outer end of the fixed hinge 110). At this time, the flip pedal 160 is subjected to a clockwise torque with the bracket pin 144 as the origin. It can be understood that when the flip pedal 160 is flipped to the outer side of the outer end surface F1 of the bottom corner piece 116 ( Figure 10 (the middle position) allows for easier application of force to the flip pedal 160 by hand or foot. The corresponding contact between the mating portion 162 of the flip pedal 160 and the blocking member 155 (the contact between the first mating surface 162a and the blocking surface 155a) allows for force transmission. Preferably, the blocking member 155 is configured such that when the flip pedal 160 is in the flip position, the blocking surface 155a is parallel and in close contact with the first mating surface 162a.

[0139] In this state, the flip pedal 160 is continuously operated to rotate about the axis of the bracket pin 144 toward the outer end face F1 of the bottom corner piece 116. The flip pedal 160 can drive the entire bracket 141 to rotate synchronously about the axis of the bracket pin 144 toward the outer end face F1 of the bottom corner piece 116 through the blocking member 155 (see Figure 12 ), thereby rotating the locking mechanism 140 to the release position.

[0140] Figure 10 In the embodiment shown, the flip pedal 160 is configured such that the center of gravity of the flip pedal 160 in the storage position is located on the side of the vertical plane where the axis of the bracket pin 144 is located, facing the mating portion 162 ( Figure 10 In this way, if the user removes the external force applied to the operating portion 161 of the flip pedal 160, the bracket 141 will return to the locking position under the action of its own weight, and drive the flip pedal 160 to rotate to the Figure 10 When the flip pedal 160 is in the flip position shown in Figure 10 When the flip position shown in FIG is turned over, the flip pedal 160 will automatically return to the storage position ( Figure 9 ), thereby allowing the flip pedal 160 to remain stably in the stored position when not in use. Thus, when this hinge device using the flip pedal 160 is used in a foldable container, the flip pedal 160 does not protrude beyond the outer contour of the container, facilitating the stacking and transportation of the foldable container.

[0141] For the same purpose, in other embodiments not disclosed in this application, additional devices may be provided to stably maintain the retractable pedal 160 in the stored position. For example, an elastic member may be provided between the mating portion 162 of the retractable pedal 160 and the bottom corner piece 116. When the retractable pedal 160 is not in use, the elastic member (elastic force) enables the retractable pedal 160 to return to the stored position and remain in the stored position.

[0142] See also Figure 11 In the second embodiment of the present application, the flip pedal 260 is configured such that the center of gravity of the flip pedal 260 in the storage position is located on the side of the vertical plane where the axis of the bracket pin 144 is located, facing the operating portion 261 ( Figure 11 In this way, without applying any external force, the flip pedal 260 will rotate around the axis of the bracket pin 144 under the action of its own weight, so that the flip pedal 260 is always in the Figure 11 , wherein the locking mechanism 140 is still in the locked position. This allows the user to directly operate the flip pedal 260 to engage the engaging portion 262 with the blocking member 155, eliminating the need to previously flip the flip pedal 260 out. It is understood that when this hinge device employing the flip pedal 260 is used in a foldable container, those skilled in the art can flexibly select a fixing method to secure the flip pedal 260 in the stowed position during container stacking or transportation, when the flip pedal 260 is not required.

[0143] The foldable container of the present application includes a base frame and end frames (not shown). A hinge device 100 is disposed between the base frame and the end frames. A movable hinge 120 is fixedly connected to the end frame, and a fixed hinge 110 is fixedly connected to the base frame. The hinge device 100 of the present application and the foldable container using the hinge device 100 of the present application can automatically lock the movable hinge 120 in the vertical position when the movable hinge 120 pivots to the vertical position, which is convenient to operate, reduces damage to the hinge device 100, and reduces the maintenance cost of the product. Furthermore, by providing a flip pedal 160 pivotally connected to the fixed hinge 110, the flip pedal 160 can be operated from the outer end side of the fixed hinge 110 to move the locking mechanism 140 from the locked position to the released position, thereby moving the movable hinge 120 from the vertical position to the horizontal position. Furthermore, the flip pedal 160 is not connected to the locking block 143. Therefore, operating the flip pedal 160 does not restrict the movement of the locking block 143, and the flip pedal 160 can also freely pivot relative to the bracket 141.

[0144] In one embodiment of the present application, the tilt pedal 160 is connected to the bracket pin 144, which is a preferred method for achieving the pivotal connection of the tilt pedal to the bracket 141. The tilt pedal 160, the bracket 141, and the fixed hinge 110 are coaxially arranged (in this embodiment, the bracket pin 144). It is understood that those skilled in the art can also achieve the pivotal connection of the tilt pedal 160 to the bracket 141 in other ways.

[0145] See also Figure 13 In the third embodiment of the present application, a first flip pedal shaft 364 may be provided between a pair of side plates of the bracket 141, so that the flip pedal 360 can rotate relative to the bracket 141 around the axis of the first flip pedal shaft 364. Figure 13 As shown, the flip pedal 360 includes an operating portion 361 and a mating portion 362, respectively located on either side of a first flip pedal shaft 364. The connecting hole of the flip pedal 360 is connected to the first flip pedal shaft 364. The flip pedal 360 rotates around the axis of the first flip pedal shaft 364 between a storage position and a flip position.

[0146] In the storage position, the matching portion 362 of the flip pedal 360 does not contact the blocking member 155 , and the operating portion 361 does not extend beyond the vertical plane where the outer end of the fixed hinge 110 is located.

[0147] In the flip position (not shown), the engaging portion 362 abuts against the blocking member 155, and the operating portion 361 extends beyond the vertical plane where the outer end of the fixed hinge 110 is located. It is easy to understand that when the flip pedal 360 is rotated until the engaging portion 362 abuts against the blocking member 155 (cooperates with the blocking member 155), if the flip pedal 360 is continued to be operated (toward the outer end of the fixed hinge 110), the bracket 141 can also be rotated around the axis of the bracket pin 144, thereby achieving the effect of rotating the bracket 141 relative to the fixed hinge 110. Figure 13 As shown, the first flip pedal pivot 364 is located above the bracket pin 144. It will be appreciated that in this embodiment, the center of gravity of the flip pedal 360 can also be designed with reference to the previous two embodiments. It will be appreciated that in this embodiment, the direction of the outer end of the fixed hinge 110 is also the direction of the outer end of the bracket 141.

[0148] See also Figure 14 In the fourth embodiment of the present application, a second flip pedal shaft 464 may be provided between a pair of wall panels of the fixed hinge 110, so that the flip pedal 460 can rotate relative to the fixed hinge 110 around the axis of the second flip pedal shaft 464. Figure 14 As shown, the flip pedal 460 includes an operating portion 461 and a mating portion 462, respectively located on either side of a second flip pedal shaft 464. The connecting hole of the flip pedal 460 is connected to the second flip pedal shaft 464. The flip pedal 460 rotates around the axis of the second flip pedal shaft 464 between a storage position and a flip position.

[0149] In the storage position, the matching portion 462 of the flip pedal 460 does not contact the blocking member 155 , and the operating portion 461 does not extend beyond the vertical plane where the outer end of the fixed hinge 110 is located.

[0150] In the flip position (not shown), the engaging portion 462 abuts the blocking member 155, and the operating portion 461 extends beyond the vertical plane of the outer end of the fixed hinge 110. When the flip pedal 460 rotates about the axis of the second flip pedal rotating shaft 464, the engaging portion 462 of the flip pedal 460 can also engage with the blocking member 155 provided to the bracket 141. Continued operation of the flip pedal 460 (toward the outer end of the fixed hinge 110) can also drive the bracket 141 to rotate about the axis of the bracket pin 144, thereby achieving the effect of rotating the bracket 141 relative to the fixed hinge 110.

[0151] like Figure 14 As shown, the bracket 141 is pivotally connected to the fixed hinge 110 through the bracket pin 144, and a stopper 441 is provided on at least one of the pair of wall panels of the fixed hinge 110. The stopper 441 is located below the bracket 141 and between the bracket pin 144 and the pivot shaft 130 (see FIG. Figure 14), the stopper 441 and the bracket pin 144 jointly support the bracket 141. The second flip pedal shaft 464 is parallel to the bracket pin 144 and is located below the bracket pin 144. The flip pedal 460 is located between a pair of side plates of the bracket 141. In this way, when the bracket 141 rotates about the axis of the bracket pin 144, the second flip pedal shaft 464 and the flip pedal 460 will not hinder the rotation of the bracket 141. The blocking member 155 is located between the bracket pin 144 and the second flip pedal shaft 464. It will be understood that in this embodiment, the center of gravity position of the flip pedal 460 can also be designed with reference to the previous embodiment.
