It is to be understood, however, that the carrying handle or handles may be positioned at any suitable location, and in any appropriate orientation, on the pushchair frame without sacrificing any of the advantages of the present invention. Moreover, additional handles may be included to further facilitate manipulation of the pushchair frame depending on the particular application of the frame.
Preferably, the pushchair frame further comprises actuation means coupled to the releasable locking mechanism and operable to unlock the yoke and the front and rear wheel frames from their operating position. The actuation means are arranged for operation by the parent or carer and are preferably disposed on each of the carrying handles, or alternatively, on the push/pull handle, or both as required. In preferred arrangements, the actuation means are integrally combined with each carrying handle, such that each handle includes an elongate depressible ‘pad’ mounted on a rotatable grip that when depressed releases the grip so that it may be partly or fully rotated in order to facilitate unlocking of the releasable locking mechanism. The actuation means are preferably connected to the locking mechanism by way of a mechanical coupling. In preferred embodiments, each carrying handle may independently perform the function of unlocking the yoke and the front and rear wheel frames from their operating position, in response to the parent or carer performing a ‘press and twist’ action on either carrying handle.
By “operating position” we mean the position the pushchair frame adopts during normal use of the pushchair (i.e. when not collapsed or stowed), and corresponds to an arrangement in which the front and rear wheel frames are spaced from one another and the yoke is in an orientation in which it is neither generally adjacent to either the front or rear wheel frames. In such a position the yoke may typically be regarded as being in a substantially “upright” position relative to the wheel frames and the surface of the ground or floor on which the wheels are located.
To facilitate operation and manipulation of the pushchair frame, at least one carrying handle is preferably disposed on the rotatable yoke. The handle may be manually gripped by the parent or carer to facilitate collapsing and subsequent unfolding of the frame, as well as being useful for carrying the folded frame. Preferably, the pushchair frame comprises a pair of carrying handles, preferably oppositely disposed on either side of the yoke. In other words, one handle is preferably provided towards the front-facing side of the yoke and the other is preferably provided towards the rear-facing side of the yoke. An advantage of providing two oppositely opposed handles is that ease of operation can be maintained irrespective of whether the attached seat is either front-facing or rear-facing, as the parent or carer can manually grip whichever handle is on the side of the pushchair that is most convenient for them.
