Abstract: A container (1) with collapsible sides (3a,3b,3c,3d,5a,5b), wherein at least one side (3a) is provided with at least one pivotally mounted lock handle (12) with a lock pin (13) that can, while protruding from the side (3a), be introduced into an opening (14) in an abutting side (3d), wherein the lock pin (13) can, by turning of the lock handle (12), be caused to lockingly engage with the opening (14). The lock handle (12) is pivotally mounted in such a manner that in this locking position as well as in its resting position in which the lock pin does not engage with the opening (14) is situated substantially along the side (3a), while in other positions it protrudes considerably from the side (3a). The lock handle (12) is provided with a spring mechanism that will, irrespective of the position of the lock handle, influence it with a force in a direction towards its locking and resting positions.

Abstract: A rollercarriage having a carriage bottom below which a plurality of wheels (3, 5) is mounted, at least one of the wheels being mounted swingably about a substantially vertical swivel axis (7) which does not intersect the axis for the rotation of the wheel. The roller carriage is moreover provided with retention means to retain the at least one swingably mounted wheel (5) on an overlying roller carriage. The retention means comprise a support face (8) which supports the swingably mounted wheel at a support point (18), an outer engagement area (16) extending at least partly about the swivel axis (7), and an inner engagement area (16) positioned between the swivel axis (7) and the outer engagement are (16), said outer and inner engagement areas restricting the rolling movement of the at least one swingably mounted wheel (5) on an overlying roller carriage.

Abstract: A roller carriage has a carriage bottom below which a plurality of wheels is mounted, at least one of the wheels being mounted swingably about a substantially vertical axis of swing. The roller carriage moreover has retention device to retain the swingable wheel or wheels on an overlying roller carriage, the wheel retention device being constructed as a substantially horizontal guide track which extends along at least part of a circle. The guide track forms two engagement areas which restrict the movement of the swingable wheel or wheels of an overlying roller carriage.
