Flexible galley cart caster guides

1. A resilient caster guide comprising:

a mounting flange configured to be received against a wall of a storage compartment for a galley cart; and

a flexible alignment element angularly extending from the mounting flange into the storage compartment, said flexible alignment element incorporating a curved portion terminating in a bead distal from the mounting flange, said curved portion enhancing flexibility in a lateral direction and said bead enhancing stability of the flexible alignment element in a longitudinal direction to induce resilient recovery, said flexible alignment element configured to contact a caster extending from a base of the galley cart received in the storage compartment and to resiliently deform to maintain longitudinal alignment of the caster.

2. The resilient caster guide as defined in claim 1 wherein the curved portion curves downward toward a floor of the storage compartment to urge downward flexing of the flexible alignment element when contacted by the caster and inducing lateral displacement of the bead.

3. The resilient caster guide as defined in claim 1 wherein the flexible alignment element has an angle of greater than 90° with respect to the mounting flange.

4. The resilient caster guide as defined in claim 1 wherein the mounting flange incorporates a plurality of slotted apertures to receive fasteners therethrough to fix the flange to the wall of the galley cart storage compartment.

5. The resilient caster guide as defined in claim 4 wherein the slotted apertures are vertically oriented to allow leveling and height adjustment of the caster guide.

6. The resilient caster guide as defined in claim 1 wherein the flexible alignment element engages the caster upon entry of the galley cart into the storage compartment and maintains engagement of the caster through an insertion length of the galley cart into the storage compartment.

7. The resilient caster guide as defined in claim 1 wherein the flexible alignment element has a lateral flex range accommodating varying placement of the caster on the base of the cart.

8. The resilient caster guide as defined in claim 1 wherein the flexible alignment element is formed of plastic or polycarbonate.

9. A galley cart storage compartment comprising:

walls extending from a floor, said walls spaced to accommodate insertion of a galley cart;

a mounting flange configured to be received against an associated one of the walls; and,

a flexible alignment element angularly extending from the mounting flange into the storage compartment, said flexible alignment element configured to contact a caster extending from a base of the galley cart received between the walls and to resiliently deform to maintain longitudinal alignment of the caster.

10. The galley cart storage compartment as defined in claim 9 wherein the flexible alignment element incorporates a curved portion terminating in a bead distal from the mounting flange, a lower surface of the curved portion partially defining a cavity and the associated one of the walls further defining the cavity providing open access for inspection and cleaning of the lower surface.

11. The galley cart storage compartment as defined in claim 9 wherein the flexible alignment element has a lateral flex range that accommodates varying configurations of placement of the caster on the base.

12. The galley cart storage compartment as defined in claim 9 wherein the flexible alignment element has a leading edge including a chamfer to receive and direct the caster during insertion.

13. The galley cart storage compartment as defined in claim 9 wherein the mounting flange incorporates a plurality of slotted apertures and the galley cart storage compartment further comprises fasteners received through the slotted apertures to fix the flange to the associated one of the walls.

14. A method for caster alignment control comprising:

providing a storage compartment having walls extending from a floor, said walls spaced to accommodate insertion of a galley cart;

providing a mounting flange configured to be received against an associated one of the walls; and,

providing a flexible alignment element angularly extending from the mounting flange into the storage compartment, said flexible alignment element configured to contact a caster extending from a base of the galley cart received between the walls and to resiliently deform to maintain longitudinal alignment of the caster;

receiving the galley cart in an entry of the storage compartment;

longitudinally engaging the caster on the cart with the flexible alignment element extending in an undeformed shape from one of the walls of the storage compartment;

resiliently flexing the flexible alignment element for displacement laterally but maintaining engagement with the caster; and

longitudinally constraining the caster with the flexible alignment element to maintain alignment of the caster for insertion and extraction of the cart from the storage compartment.

15. The method as defined in claim 14 wherein the step of longitudinally engaging includes engaging the caster with a chamfered edge.

16. The method as defined in claim 14 wherein the flexible alignment element is curved and wherein the step of resiliently flexing comprises flexing downwardly to receive the caster.

17. The method as defined in claim 14 further comprising:

maintaining contact with the caster with the flexible alignment element when the cart is present in the storage compartment; and

reducing vibration induced noise during taxi, take-off, turbulence, and landing.

18. The method as defined in claim 14 further comprising:

removing the cart from the storage compartment; and

resiliently returning the flexible alignment element to the undeformed shape.

19. The method as defined in claim 14 wherein the step of resiliently flexing includes flexing over a flex range to receive the caster with differing configuration on the galley cart.

20. The galley cart storage compartment as defined in claim 9 wherein the flexible alignment element has an angle of greater than 90° with respect to the mounting flange.
