The present specification generally relates to hinges for opening doors in a container and, more specifically, to hinges that provide multiple axes of rotation for a door of a shipping container.
Containers can be utilized to assist with transporting and storing goods of various size, weight, and composition. For example, a container can be provided as a box that provides a top opening for loading goods into the box. The container can include a lower interface for handling by a transport device. Typical transport devices can include forklifts, pallet jacks, front loaders, or the like. Some containers can be provided with drop down doors to facilitate the loading of goods into a container by expanding the size of the top opening.
However, the drop down doors can weaken the structure of the container by providing a point of failure. Accordingly, goods may be lost or damaged should the door fail. Some containers include locking features that secure the door to the container. However, such locking features can be complex and make the door inefficient to open. Further, such locking features may alter the opening geometry and prevent the door from fully opening. The door can thus create an obstruction that makes the container more difficult to load and reduces the efficacy of the door.
Accordingly, a need exists for alternative hinges that provide multiple axes of rotation for a door of a shipping container.
In one embodiment, a multi-axis hinge can include a fixed axis body and an articulating body. The fixed axis body and the articulating body can be in rotational engagement and can be configured to rotate with respect to one another around a hinge rotational axis. The fixed axis body can include a first pillar and a second pillar that extends away from the hinge rotational axis. The first pillar and the second pillar can each include a panel engagement member. The articulating body can include a first articulating pillar and a second articulating pillar that extends away from the hinge rotational axis. The first articulating pillar and the second articulating pillar can each include a door engagement member.
In another embodiment, a container can include a multi-axis hinge, an access panel, and a door. The multi-axis hinge can include a fixed axis body and an articulating body. The fixed axis body and the articulating body can be in rotational engagement and can be configured to rotate with respect to one another around a hinge rotational axis. The access panel can comprise a doorway that forms a recess that extends from an upper perimeter of the container towards a base of the container. The fixed axis body of the multi-axis hinge can be in rotational engagement with the access panel. The door can be configured to selectively close and open with respect to the doorway. The articulating body of the multi-axis hinge can form a rotational and sliding engagement with the door.
In a further embodiment, a container can include a multi-axis hinge, an access panel, and a door. The multi-axis hinge can include a fixed axis body and an articulating body. The fixed axis body and the articulating body can be in rotational engagement and can be configured to rotate with respect to one another around a hinge rotational axis. The access panel can comprise a doorway that forms a recess that extends from an upper perimeter of the container towards a base of the container. The fixed axis body of the multi-axis hinge can be in rotational engagement with the access panel to define a fixed axis of rotation. The door can be configured to selectively close and open with respect to the doorway.

The access panel 110 can comprise one or more pocket members 114 configured to selectively prevent motion of a door 130 with respect to a fixed axis of rotation 132. Specifically, the pocket member 114 can form a cavity adjacent to the doorway 112. For example, each pocket member 114 can form a cavity along a transitional feature 116 that is positioned along the access panel 110 adjacent to the doorway 112. In some embodiments, the pocket member 114 can comprise a spacer 118 offset from the transitional feature 116 such that the spacer is nearer to the doorway 112 than the transitional feature 116. The pocket member 114 can further comprise an outer bounding feature 120 that spans the distance between the transitional feature 116 and the spacer 118. The outer bounding feature 120 can be thinner than the transitional feature 116 and the spacer 118. Accordingly, a cavity can be formed by the transitional feature 116, the spacer 118, and the outer bounding feature 120. Alternatively or additionally, the access panel 110 can comprise an inner bounding feature 122 configured to delimit the motion of the door 130 with respect to the fixed axis of rotation 132. In some embodiments, the inner bounding feature 122 can extend from the doorway 112 towards the transitional feature 116. The inner bounding feature 122 can be offset from the outer bounding feature 120 by the spacer 118. Accordingly, the cavity can be located between the outer bounding feature 120 and the inner bounding feature 122.
In embodiments with multiple pocket members 114, the pocket members 114 can be arranged in a substantially serrated pattern. For example, the pocket members 114 can be aligned in a substantially linear column and separated from one another. Each outer bounding feature 120 can form projections having a span 124 there between. In some embodiments, the inner bounding feature 122 can be larger than the outer bounding feature 120. Accordingly, the inner bounding feature 122 can at least partially cover the span 124 between each of the pocket members 114.

The locking member 136 can be configured to engage with the pocket member 114 of the doorway 112. Accordingly, the locking member 136 can be shaped to fit within the cavity bounded by the pocket member 114, i.e., the locking member 136 can be correspondingly shaped to the cavity. Alternatively or additionally, the locking member 136 can extend from the projecting member 134 towards the pocket member 114, when the door 130 is in the closed position. For example, when the door 130 is in the closed position, the locking member 136 can extend substantially downwards from the projecting member 134.

The multi-axis hinge 140 can comprise a stop feature 152 configured to set a predetermined angle 154 between the fixed axis body 142 and the articulating body 144 with respect to the hinge rotational axis 146. In some embodiments, the first joint member 148, the second joint member 150, or both can comprise an angled face 156 positioned adjacent to the hinge rotational axis 146. For example, each of the first joint member 148 and the second joint member 150 can comprise an angled face 156 that bounds the motion of the fixed axis body 142 and the articulating body 144 around the hinge rotational axis 146. Thus, when the angled faces 156 come into contact, additional rotation of the fixed axis body 142 and the articulating body 144 around the hinge rotational axis 146 can be mitigated. In some embodiments, the predetermined angle 154 can be between about 75° and about 105° such as, for example, between about 80° and about 100° in one embodiment, or between about 80° and about 95°.
The fixed axis body 142 can comprise a first pillar 158 and a second pillar 160 configured to offset the hinge rotational axis 146 from the fixed axis of rotation 132. Specifically, each of the first pillar 158 and the second pillar 160 can be an elongate body that extends away from the first joint member 148 of the fixed axis body 142. In some embodiments, the first pillar 158 and the second pillar 160 can be offset from one another along the fixed axis of rotation 132. In one embodiment, the first pillar 158 and the second pillar 160 can be substantially parallel. Each of the first pillar 158 and the second pillar 160 can comprise a panel engagement member 162 that is configured to form a rotational engagement with the access panel 110 along the fixed axis of rotation 132. Accordingly, the panel engagement member 162 can be offset from the first joint member 146 of the fixed axis body 142. In some embodiments, the panel engagement member 162 can be a substantially cylindrical pillar that extends from one or both of the first pillar 158 and the second pillar 160 and along the fixed axis of rotation 132. Alternatively or additionally, the panel engagement member 162 can be a cylindrical bore (
The articulating body 144 can comprise a first articulating pillar 164 and a second articulating pillar 166 configured to offset a sliding rotational axis 168 from the fixed axis of rotation 132. Specifically, each of the first articulating pillar 164 and the second articulating pillar 166 can be an elongate body that extends away from the second joint member 150 of the articulating body 144. In some embodiments, the first articulating pillar 164 and the second articulating pillar 166 can be offset from one another along the sliding rotational axis 168. In one embodiment, the first articulating pillar 164 and the second articulating pillar 166 can be substantially parallel. Each of the first articulating pillar 164 and the second articulating pillar 166 can comprise a door engagement member 170 that is configured to form a sliding and rotational engagement with the door 130 such that the door 130 can slide with and rotate along the sliding rotational axis 168. Accordingly, the door engagement member 170 can be offset from the second joint member 150 of the articulating body 144. In some embodiments, the door engagement member 170 can be a substantially cylindrical pillar that extends from one or both of the first articulating pillar 164 and the second articulating pillar 166 and along the sliding rotational axis 168. Alternatively or additionally, the door engagement member 170 can be an elongate slot (
According to the embodiments described herein, the multi-axis hinge 140 can be substantially “H” shaped. For example, the first pillar 158 of the fixed axis body 142 can be aligned with the first articulating pillar 164 of the articulating body 144 and the second pillar 160 of the fixed axis body 142 can be aligned with the second articulating pillar 166 of the articulating body 144. Alternatively or additionally, the hinge rotational axis 146 can be offset from the fixed axis of rotation 132 by a distance that is less than the offset between the hinge rotational axis 146 and the sliding rotational axis 168. Accordingly, the first pillar 158 of the fixed axis body 142 can extend a shorter length than the first articulating pillar 164, the second articulating pillar 166, or both. Likewise, the second pillar 160 of the fixed axis body 142 can extend a shorter length than the first articulating pillar 164, the second articulating pillar 166, or both.
The multi-axis hinge 140 can also comprise one or more cantilevered detents configured to couple the multi-axis hinge 140 to the container 100. For example, the fixed axis body 142 can comprise a first cantilevered detent 172 that extends from the second pillar 160 towards the first pillar 158. The first cantilevered detent 172 can be substantially aligned with the fixed axis of rotation 132. In some embodiments, the first cantilevered detent 172 can extend only partially across the span between the second pillar 160 and the first pillar 158. Alternatively or additionally, the articulating body 144 can comprise a second cantilevered detent 174 that extends from the second articulating pillar 166 towards the first articulating pillar 164. The second cantilevered detent 174 can be substantially aligned with the sliding rotational axis 168. In some embodiments, the second cantilevered detent 174 can extend only partially across the span between the second articulating pillar 166 and the first articulating pillar 164. Accordingly, the second cantilevered detent 174 can act as a follower to a surface substantially perpendicular to the hinge rotational axis 146 to guide articulation of the articulating body 144. It is noted that, while the first cantilevered detent 172 is depicted as extending from the second pillar 160, the first cantilevered detent 172 can extend from the first pillar 158 without departing from the scope of the present disclosure. Likewise, while the second cantilevered detent 174 is depicted as extending from the second articulating pillar 166, the second cantilevered detent 174 can extend from the first articulating pillar 164. It is furthermore noted that each of the first cantilevered detent 172 and the second cantilevered detent 174 can be configured to flex or deflect during installation of the multi-axis hinge 140 to the container 100.

The multi-axis hinge 140 can be in rotational and sliding engagement with the door 130 to promote a sequence of motion of the door 130. In some embodiments, the door 130 can comprise one or more sliding engagement members 186 each configured to form a rotational and sliding engagement with the door engagement member 170 of the articulating body 144 of the multi-axis hinge 140. Accordingly, the door 130 can translate with respect to the sliding rotational axis 168. Generally, the sliding engagement member 186 is correspondingly shaped to the door engagement member 170. In some embodiments, the sliding engagement members 186 can comprise an elongate slot configured to receive the door engagement member 170 in a rotational and sliding engagement. Alternatively or additionally, the sliding engagement members 186 can comprise a substantially cylindrical pillar configured to be received by the door engagement member 170 (

In some embodiments, the access panel 110 can comprise a panel engagement feature 191 such as a recess or corrugation provided along the bottom of the doorway 112 that is configured to receive a bottom edge 192 of the door 130. Thus, when the door 130 is in the first state 10, the panel engagement feature 191 can overlap the bottom edge 192 of the door 130 such that rotation of the door 130 around the fixed axis of rotation 132 is mitigated. The amount of overlap can be less the span 124 between the pocket members 114. Accordingly, motion of the door 130 can be unobstructed by the panel engagement feature 191 when the door 130 is in the second state 12.
Generally, the door 130 can translate between the first state 10 and the second state 12 via substantially vertical motion along the doorway 112. Specifically, the door 130 can translate with respect to the sliding rotational axis 168. For example, the sliding engagement member 186 of the door 130 and the door engagement member 170 of the multi-axis hinge 140 can move linearly with respect to one another to transition between the first state 10 and the second state 12. When in the second state 12, the door 130 and the multi-axis hinge 140 can be free to rotate with respect to the fixed axis of rotation 132, the hinge rotational axis 146, and the sliding rotational axis 168. Accordingly, the door 130 can be opened by rotating along the fixed axis of rotation 132, the hinge rotational axis 146, the sliding rotational axis 168, or a combination thereof to transition from the second state 12 to a third state 14. Likewise, the door 130 can be closed by rotating along the fixed axis of rotation 132, the hinge rotational axis 146, the sliding rotational axis 168, or a combination thereof to transition from the third state 14 to the second state 12.
