Definitions
- This invention relates generally to folding strollers of the type adapted to carry two passengers (children), where one child is positioned behind and lower than the other.
- a problem with known strollers of the above described type is that they have an awkward folding action that requires significant repositioning of both seats in order to facilitate their folding to a collapsed configuration and back again.
- a stroller adapted to be folded between an in use configuration and a collapsed configuration, the stroller comprising a first passenger support, and a second seat adapted to be moved between an in use position and a stowed position, wherein the stroller is adapted to fold to the collapsed configuration when and only when the second seat is in the stowed position.
- the invention may be said to include a stroller comprising a first passenger support and a second seat, the stroller being adapted to be folded between an in use configuration and a collapsed configuration in two stages, the first stage comprising a movement of the second seat from an in use position to a stowed position, and the second stage being a folding of the stroller. Returning the stroller to the in use configuration then would require reversal of these stages.
- the invention may be said to include a stroller comprising a first passenger support and a second seat having an in use position and a stowed position, where the second seat can be moved between the in use and stowed positions and back again, without needing to move the first passenger support.
- the in use position for the second seat is both behind and lower than the first passenger support.
- the stroller When in the collapsed configuration, the stroller is not useable and is folded so as to be generally flattened and thereby consume less space. When in the in use configuration, the stroller is configured to receive and transport either one or two passengers in a manner well understood in the art.
- the first passenger support is also a seat.
- the first passenger support may be a bassinet or the like.
- the second seat is adapted to move to and from the stowed position with a combined sliding and rotating action.
- the stroller comprises a first frame assembly supporting the first seat, and a second frame assembly supporting the second seat, the second frame assembly being pivotally connected to the first frame assembly.
- the first frame assembly is comprised of an upper sub frame and a lower sub frame, where these are pivotally connected to one another via a releasably lockable hinge mechanism, for folding between the in use configuration and the collapsed configuration and back again.
- the lower sub frame comprises at least one wheel assembly at or toward a lowermost end thereof.
- the upper sub frame of the first frame assembly supports the first seat and provides a handle at or toward an uppermost end thereof.
- the second frame assembly comprises a pair of arms, where each of these arms is pivotally connected to the lower sub frame of the first frame assembly at or toward a first end thereof, and where each of these arms supports a wheel assembly at or toward a second end thereof.
- the second seat is supported on a carriage frame which in turn is supported between the arms of the second frame assembly.
- this carriage frame (and the second seat supported thereby) may be removably secured to the arms of the second frame assembly.
- the second seat is adapted to slide along and pivot relative to this carriage frame so that it may move between its in use (i.e. inclined) and stowed (i.e. reclined) positions.
- the carriage frame comprises user operable locking means which permit the second seat to be locked in at least the in use and stowed positions.
- the invention may be said to include a method of folding the above described stroller between the in use and collapsed configurations, or visa-versa.
- a stroller configured for use is collapsed by firstly releasing the carriage locking mechanism and sliding the second seat along the carriage and toward the first end of the arms, this simultaneously causing the second seat to recline to a stowed position close to the arms, the releasably lockable hinge mechanism of the first frame assembly can then be released and the lower sub frame of this folded beneath both the upper sub frame and the second frame assembly, this being the strollers collapsed configuration.
- the stroller can be returned to the in use configuration by reversing this process.
- Figure 1 is a perspective view of an exemplary stroller in its in use configuration, with the second seat fully inclined (i.e. in it's in use position);
- Figure 2 is a side view of the stroller in Figure 1, in it's in use configuration
- Figures 3 and 4 are side views of the stroller in Figures 1 and 2, illustrating successive stages of the second seats movement, ranging from its fully inclined position to its stowed position;
- Figures 5 through 9 are side views of the stroller in Figures 1 through 4, illustrating successive stages of the strollers folding action as it is folded into its collapsed configuration;
- Figure 10 is a detail view in which the first seat has been removed to permit visibility of the carriage locking means
- Figure 11 is a detail view in which the seat padding and material has been removed to permit visibility of the seat frame and the carriage locking means;
- Figure 12 is a perspective schematic of the stroller illustrating the carriage locking means.
- FIG. 1 where there is illustrated a stroller 1 having a first seat 2 and a second seat 4 positioned behind and lower than the first seat 2.
- the stroller comprises a first frame assembly 6 removably supporting the first seat 2, and a second frame assembly 8 removably supporting the second seat 4.
- the first and second seats 2 and 4 are removably attached to their respective frame assemblies 6 and 8 using releasable connector fittings of a type well understood in the relevant art.
- these connector fittings employ spring loaded catches or pins either operated or released by buttons or levers.
- the frame assemblies referenced herein are fabricated from a tubular metal material, such as steel or aluminium.
- the first seat 2 is connected to the first frame assembly 6 via an adaptor which repositions the first seat 2 upward and forward and thereby provides additional space for the second seat 4 and its occupant behind and lower than the first seat 2.
- the first frame assembly 6 is comprised of an upper sub frame 6a and a lower sub frame 6b, where these are pivotally connected to one another via a releasably lockable hinge mechanism at A, so as to permit the folding of these sub frames 6a and 6b relative to each other between an in use configuration and a collapsed configuration and back again.
- the lower sub frame 6b comprises one or more (a pair in this case) removable castor wheel assemblies 10 at a lowermost end thereof. In use, these castor wheel assemblies 10 permit steering of the stroller 1.
- the upper sub frame 6a of the first frame assembly 6 supports the first seat 2 and comprises a handle 12 at an uppermost end thereof.
- the releasably lockable hinge mechanism at A is adapted to provide user releasable locking for securing the upper and lower sub frames 6a and 6b in the in use configuration (as illustrated in Figures 1 and 2), or release these so that they may be folded to the collapsed configuration (as illustrated in Figure 9) .
- This releasably lockable hinge mechanism A will also be of a type well understood in the art. Again, these releasably lockable hinge mechanisms typically employ spring loaded catches or pins either operated or released by buttons or levers.
- the second frame assembly 8 comprises a pair of arms 8a, where each of these arms 8a is pivotally connected to the lower sub frame 6b of the first frame assembly 6 at a first end thereof at point B. Each of these arms 8b supports a removable rear wheel assembly 14 at a second end thereof.
- the second seat 4 is supported on a carriage frame 20 which in turn is removably supported between the arms 8a of the second frame assembly 8.
- the second seat 4 is adapted to slide relative to carriage frame 20 between its in use (as illustrated in Figures 1 and 2) and stowed (as illustrated in Figure 4) positions.
- the second seat 4 has a pair of oppositely directed lugs 4b projecting from the frame 4a thereof at a location toward a forward edge of the seat 4; each of theses lugs 4b locates in and may slide along a track 22 running in an inner edge of the carriage frame 20.
- the second seat 4 is also indirectly connected to the carriage frame 20 by a pair of struts 30, each strut 30 extending between a side of the back portion of the second seat 4 (i.e. aft of lugs 4b) and the carriage frame 20, and each strut 30 being pivotally connected to these at points C and D respectively.
- the second seat 4 is adapted to move to and from its stowed position with a combined sliding and rotating action. That is, as the second seat 4 slides toward the first seat 2 (i.e. the stowed position), it reclines away from the same. Conversely, as the second seat 4 slides away from the first seat 2 (i.e. toward the in use position), it inclines toward the first seat 2.
- An advantage of this combined sliding and rotating action is that is prevents any significant rearward shift of the centre of gravity of the stroller 1, which may lead to rearward toppling of a loaded stroller. That is, the centre of gravity of the stroller 1 is maintained between the front wheel assembly 10 and rear wheel assembly 14 of the stroller 1.
- the carriage frame 20 comprises user operable locking means which lock the second seat 4 in at least the in use and stowed positions.
- This locking means operates in two stages.
- a first locking or adjustment stage permits movement of the second seat 4 between an inclined position (as illustrated in Figure 2), and a partially reclined position (as illustrated in Figure 3) suitable for a child sleeping in the second seat 4. Further movement of the second seat 4 from this partially reclined position (as illustrated in Figure 3) to the stowed position (as illustrated in Figure 4) is prevented by a second locking or safety stop stage, which must be separately released before the second seat 4 can be moved from the partially reclined position (as illustrated in Figure 3) to the stowed position (as illustrated in Figure 4). This second safety stop then prevents the second seat 4 from being inadvertently moved toward the stowed position (as illustrated in Figure 4) whilst a child is seated therein.
- the adjustment stage is controlled by a handle 50 positioned on the upper back edge of the second seat 4.
- This handle 50 is connected to a wire cable 51 routed through the second seat's frame 4a to a spring loaded pin 52 that engages in one of a series of spaced apart apertures represented at 54 and 56 and located in the track 22 running in inside edge of carriage frame 20. Pulling on the handle 50 retracts the pin 52 from the aperture in which it is held captive thereby permitting the second seat 4 to slide along track 22, where releasing the handle 50 permits the pin 52 to extend and engage the next aperture that it passes.
- the safety stop is controlled by a button 60 located on the carriage frame 20 itself.
- This button 60 is connected to a catch 62 which prevents one of the seat lugs 4b from passing thereby unless the button 60 is operated thereby removing the catch 62 from in front of the lug 4b.
- a second pair of struts 40 extends between a respective side of the first frame assembly 6 and an arm 8b of the second frame assembly 8, each strut 40 being pivotally connected to these at points E and F respectively.
- a stroller 1 configured for use (as illustrated in Figure 1) is collapsed by firstly releasing the carriage locking mechanism (by releasing the two stages of this in turn) and sliding the second seat 4 toward the first end of the arms 8 a, this simultaneously causing the second seat 4 to recline to a stowed position close to the arms 8a (as illustrated in Figure 4).
- the releasably lockable hinge mechanism of the first frame assembly 6 can then be released (as illustrated in Figure 5) and the lower sub frame 6b of this folded beneath both the upper sub frame 6a and the second frame assembly 8, this being the strollers collapsed configuration (as illustrated in Figures 6 through 9).
- the stroller 1 can be returned to the in use configuration by reversing this process.
- a significant advantage of the stroller 1 described herein is that only the second seat 4 (as distinct from both seats) need be positioned (by stowing this) to facilitate the folding collapse of the stroller 1.
