Outer guard for transport refrigeration systems
An outer guard assembly or system is described, which may be used in transport units, such as for example in transport refrigeration including the units and/or systems thereof. The outer guard assembly or system includes transitions components to facilitate mounting to a trailer or container of a transport unit, so as to shift or transfer load of the mounting from the transport refrigeration unit to the trailer or container, on which the transport refrigeration unit is mounted. The outer guard in some examples includes an openable mechanism to provide clearance, such as for example to open and/or access doors, panels, equipment, and components of a transport refrigeration unit.
1. An outer guard system for a transport refrigeration unit, the transport refrigeration unit including an outermost housing that houses all of the equipment of the transport refrigeration unit, the outer guard system comprising:
an assembly of rail members that form an outer guard structure;
transition components including first transition components and second transition components; and
connection structures including first connection structures and second connection structures, wherein
the first transition components and the first connection structures are configured to mount the outer guard structure to the transport refrigeration unit outside of the outermost housing of the transport refrigeration unit,
the second transition components and the second connection structures are configured to mount the outer guard structure to a trailer or container,
the outer guard structure is configured to be disposed outside of the transport refrigeration unit, and
the assembly of rail members includes an upper guard, an intermediate guard, and a lower guard, and one or more of the upper guard, the intermediate guard, and the lower guard includes one or more of the first transition components and one or more of the second transition components.
2. The outer guard system of claim 1 , wherein the one or more of the second transition components are connected to a member of the upper guard so as to mount the outer guard structure to the trailer or container.
3. The outer guard system of claim 2 , wherein the one or more of the second transition components on the upper guard includes a transition bracket, the transition bracket including a channel.
4. The outer guard system of claim 1 , wherein the one or more of the first transition components are connected to a member of the lower guard so as to mount the outer guard structure to the transport refrigeration unit.
5. The outer guard system of claim 4 , wherein the one or more of the first transition components on the member of the lower guard includes a transition bracket and a transition bracket support plate, where the transition bracket includes a surface on which the transport refrigeration unit is mounted.
6. The outer guard system of claim 4 , wherein the one or more of the first transition components on the member of the lower guard includes multiple transition support plates and transition spacers, and
the support plates and spacers are assembled with the connection structures onto the member of the lower guard to support the outer guard structure and to mount the lower guard of the outer guard structure to the transport refrigeration unit.
7. The outer guard system of claim 1 , further comprising:
an openable mechanism located on the upper guard, the connection structures including third connection structures, and the upper guard including one or more cross members, a front member connected to the one or more cross members, and a pivotable structure, which are assembled using the third connection structures,
wherein the openable mechanism is formed by at least the front member, the one or more cross members, the pivotable structure, and the third connection structures.
8. An outer guard system for a transport refrigeration unit, comprising:
an assembly of rail members that form an outer guard structure;
transition components;
connection structures;
an openable mechanism, wherein
the transition components and the connection structures include transition components and connection structures configured to mount the outer guard structure to the transport refrigeration unit,
the transition components and the connection structures include transition components and connection structures configured to mount the outer guard structure to a trailer or container,
the assembly of rail members includes an upper guard, an intermediate guard, and a lower guard, one or more of the upper guard, the intermediate guard, and the lower guard includes one or more of the transition components configured to mount the outer guard structure onto the transport refrigeration unit and onto the trailer or container,
the openable mechanism is located on the upper guard,
the upper guard includes a front member connected to one or more cross members and a pivotable structure, which are assembled using the connection structures, and are arranged to make up the openable mechanism, and
the front member includes one or more connection structures of the connection structures and which are removable, the one or more cross members includes the pivotable structure and includes one or more connection structures of the connections structures, such that the openable mechanism is in the open state when the connection structures of the front guard are removed from connection, and the cross member(s) are moved about the pivotable structure.
