Retainer

1 . A retaining assembly for a galley comprising:

a retaining arm;

a mounting rod; and

a biasing device;

wherein the retaining arm is movable between a non-retaining position and a retaining position;

when in the retaining position, the retaining arm is arranged to prevent movement in a retaining direction;

wherein the retaining arm is adjustably mounted to the mounting rod such that its position on the mounting rod is adjustable in the retaining direction; and

wherein the biasing device is arranged to provide a biasing force on the retaining arm to bias a position of the retaining arm on the mounting rod, the biasing force configured to cause an adjustment of the position of the retaining arm on the mounting rod in a direction of the biasing force and permitting adjustment in an opposite direction by application of a force greater than the biasing force.

2 . The retaining assembly as claimed in claim 1 , further comprising a first limiter arranged to limit movement of the retaining arm caused by the biasing force.

3 . The retaining assembly as claimed in claim 2 , wherein the first limiter and the biasing device are arranged on opposite sides of the retaining arm.

4 . The retaining assembly as claimed in claim 2 , wherein the first limiter is adjustably mounted to the mounting rod such that its position on the mounting rod is adjustable in the retaining direction.

5 . The retaining assembly as claimed in claim 1 , wherein the biasing device is arranged to provide a biasing force greater than 100 Newtons.

6 . The retaining assembly as claimed in claim 1 , wherein the biasing device is arranged to provide a biasing force less than 100 Newtons.

7 . The retaining assembly as claimed in claim 1 , further comprising a second limiter arranged to limit movement of the retaining arm against the biasing force.

8 . The retaining assembly as claimed in claim 7 , wherein the second limiter and the biasing device are arranged on the same side of the retaining arm.

9 . The retaining assembly as claimed in claim 7 , wherein the second limiter is a tube or sleeve positioned around the biasing device.

10 . The retaining assembly as claimed in claim 1 , wherein the retaining arm is movable between the non-retaining position and the retaining position by rotating in a plane substantially perpendicular to the retaining direction.

11 . The retaining assembly as claimed in claim 1 , wherein the biasing device is a spring, and wherein the spring is a coil spring wound around the mounting rod.

12 . A storage unit for storing one or more items in a galley, the storage unit comprising a retaining assembly the retaining assembly comprising:

a retaining arm;

a mounting rod; and

a biasing device;

wherein the retaining arm is movable between a non-retaining position and a retaining position;

when in the retaining position, the retaining arm is arranged to prevent movement in a retaining direction;

wherein the retaining arm is adjustably mounted to the mounting rod such that its position on the mounting rod is adjustable in the retaining direction;

wherein the biasing device is arranged to provide a biasing force on the retaining arm to bias a position of the retaining arm on the mounting rod, the biasing force configured to cause an adjustment of the position of the retaining arm on the mounting rod in a direction of the biasing force and permitting adjustment in an opposite direction by application of a force greater than the biasing force, and

wherein the retaining arm is arranged to retain the one or more items in the retaining direction when the retaining arm is in the retaining position.

13 . The storage unit as claimed in claim 12 , wherein the storage unit is a galley trolley compartment and wherein the one or more items are galley trolleys.

14 . The storage unit as claimed in claim 12 , wherein the storage unit is arranged to store a first item in a rear part of the storage unit and the storage unit is arranged to store a second item in a front part of the storage unit;

wherein the retaining assembly is arranged to retain:

the first item against forward movement from the rear part; or

the second item against rearward movement from the front part; or

the first item against forward movement from the rear part and the second item against rearward movement from the front part.

15 . The storage unit as claimed in claim 14 , wherein the mounting position of the retaining arm is adjustable in use to move between a first position and second position;

wherein when in the first position, the retaining arm is arranged to retain the first item against forward movement from the rear part; and

wherein when in the second position, the retaining arm is arranged to retain the second item against rearward movement from the front part.
