The umbrella mechanism 10 of the invention comprises a central hub 12 and a plurality of elongate spokes 16, each comprising a pair of flat resilient strips 16.1 and 16.2 which may be of metal or a plastics material. One of the ends of each of the resilient strips 16.1 and 16.2 are connected to the hub 12 and the other end is connected to a canopy 66. The resilient strips 16.1 and 16.2 are movable between an extended configuration in which they extend outwardly from the hub 12 and a storage configuration in which they are wound around the hub 12 in an overlapping relationship with the other spokes 16. Guide formations 20, radially arranged around the hub 12, facilitate movement of the spokes 16 between their extended and storage configurations. The umbrella mechanism also includes a handle 14 which comprises a piece of strip material which is coiled within the hub 12 in its inoperative configuration and which is uncoiled into an extended volute spring shape in its operative position.
