Mobile cooling box with hinge module
A mobile cooling box having a box main body and at least one lid for opening the box and providing access to the inside of the box. The at least one lid is pivotally attached to the box main body by at least two hinge modules. Each hinge module comprises a pin module having a hinge pin with a front end, a rear end, a longitudinal axis about which the lid is pivotable and predominantly a smooth outer surface of a cylindrical shape. Each hinge module further comprises a bearing module having a hinge bearing accommodating the hinge pin. The hinge pin laterally extends with its front end into the hinge bearing. Thus, during pivoting the lid with respect to the box main body an axis of the hinge bearing remains co-linear with the longitudinal axis of the hinge pin.
1. A mobile cooling box, comprising:
a box main body having a lid disposed over an opening of the box main body;
the lid being pivotally attached to the box main body by two hinge modules, each hinge module of said two hinge modules being disposed at an end of the lid to provide pivoting movement of the lid relative to the box main body;
each of said two hinge modules having a hinge pin defining a longitudinal axis between a first end and a second end, said lid having said pivoting movement about said longitudinal axis;
a bearing module having a bearing which receives said hinge pin;
said lid capable of being pivotable to a preselected position and capable of being removed from the hinge pin but incapable of removal when in a closed position.
2. The mobile cooling box of claim 1 , further comprising a thread at one of said first end or said second end, and a tool engagement portion at the other of said first end or said second end.
3. The mobile cooling box of claim 2 , further comprising a backing plate disposed between the hinge pin and the thread.
4. The mobile cooling box of claim 2 , said bearing module having a spring element which retains said hinge pin in said bearing module.
5. The mobile cooling box of claim 1 said hinge pin disposed in a vertical surface of said box main body.
6. The mobile cooling box of claim 1 , said box main body having a first pair of long sides and a second pair of short sides.
7. The mobile cooling box of claim 6 , said lid pivotally connected along one long side of said first pair of long sides.
8. The mobile cooling box of claim 7 , said lid being a first lid and a second lid.
9. The mobile cooling box of claim 6 , said lid pivotally connected along one short side of said second pair of short sides.
10. The mobile cooling box of claim 1 , said box main body having an interior floor comprising a first elevation and a second, different elevation.
11. The mobile cooling box of claim 10 , further comprising an evaporator beneath a higher elevation of said first elevation or said second, different elevation.
12. The mobile cooling box of claim 1 further comprising spring loaded handles which are biased toward said box main body.
13. A mobile cooling box, comprising:
a box main body and a lid pivotally connected to said box main body;
a hinge module disposed at each of two ends of said lid, said hinge module having a hinge pin and a bearing which allows for pivotal movement to open and close said lid;
a spring disposed adjacent to said hinge pin to retain said hinge pin in said bearing, said spring deflecting to allow removal of said lid at a preselected position;
an engaging portion which is co-linear with said hinge pin and separated by a backing plate.
14. The mobile cooling box of claim 13 , said engaging portion threadably engaging a vertical surface of said box main body.
15. The mobile cooling box of claim 13 said hinge pin being predominantly cylindrical and having a smooth outer surface.
16. The mobile cooling box of claim 13 , further comprising a tool engagement portion within said hinge pin at a first end.
