Description

Baby carriage

Technical Field

The present invention relates to a baby carriage and a method of operating a baby carriage.

Background

Infants and toddlers are transported by a wide variety of styles and names of unpowered wheeled vehicles. Infants and very small infants are often placed on flat beds or tilt chairs mounted on wheeled undercarriages, which are commonly referred to as "strollers", "pushchairs" or "strollers". Larger infants and toddlers may be transported through less secure, mostly fabric seats, sometimes referred to as "strollers". These terms are often used interchangeably and in the following description the term "stroller" will be used to cover all such vehicles for children from birth to toddlers.

As infants grow, the requirements for vehicles change. For example, while most of the time a newborn baby must be allowed to lie flat, a larger baby may wish to sit up and view the world around him. Various solutions to this necessary conversion are proposed in the prior art, including seats adjustable between upright and lying configurations, and modular systems in which a plurality of different vehicle bodies can be interchangeably accommodated on a common chassis.

In the trolley market, there are a variety of designs that can meet the different needs of the user. From large pushchairs with movable seating units to small compact prams with fabric seats fixed directly to the frame. In addition to the weight difference of each trolley, the main difference is mainly in what kind of seat is used. Factors such as wheel size may give different "push" characteristics and may cope with different terrains, all variables in the design of the pushchair.

To aid in differentiation, carts are sometimes divided into two specific areas:

a movable seat providing a forward and parent facing configuration. These typically have an attachment point around the center of the chassis which allows the seat to be clipped on and off, as well as using the same fasteners to place the crib or car seat in place.

A "fixed" seat, which is typically a "fabric harness" that is directly fixed to the chassis.

SUMMERY OF THE UTILITY MODEL

There are various disadvantages in prior art vehicles including, but not limited to, being overly heavy, difficult to fold, versatility, and cost. Embodiments of the present invention aim to provide a trolley in which at least some of the problems of the prior art are at least partially solved.

The utility model is defined by the appended independent claims to which reference should now be made. Further, preferred features can be found in the dependent claims thereof.

According to one aspect of the present invention there is provided a baby stroller comprising a chassis and a plurality of ground wheels, the chassis comprising a lower mount and an upper mount for mounting a baby support, wherein, in the case of at least one type of support, the chassis is arranged to interchangeably accommodate a plurality of different baby supports by engagement of the support with only the lower mount, and in the case of at least one other type of support, the chassis is arranged to interchangeably accommodate a plurality of different baby supports by engagement of the support with both the lower mount and the upper mount.

At least one support may be mounted on the lower mount only and at least one other support may be mounted on both the lower mount and the upper mount.

The support may comprise a seat or a bed.

In this way, the lower fixture may be used to accommodate both forward and rearward facing seats, or a crib/bed used with an undercarriage, but when combined with the upper fixture, lighter seats may be attached to the undercarriage. This allows a single chassis to adapt to different needs, avoiding the purchase of another chassis.

According to another aspect of the present invention there is provided a baby stroller comprising a base frame, a plurality of wheels and a support for a baby, wherein the support comprises: a first lower portion mounted on a lower mounting of the undercarriage; and a second upper portion releasably attached to the upper mount of the undercarriage.

The lower portion of the seat includes a seat base and the upper portion of the seat includes a seat back.

The lower and/or upper portion of the seat may comprise a sheet of material. Preferably, the material is a fabric.

In a preferred arrangement, the upper portion is releasably attached to the upper mount of the chassis in at least two spaced apart positions on the chassis, more preferably on a handle portion of the cart.

At least a second portion of the seat is attachable to the chassis by engagement of a first attachment member mounted on an upper portion of the seat and a second attachment member on an upper mount of the chassis.

According to another aspect of the present invention, there is provided a foldable stroller, comprising: a chassis including a handle portion; a plurality of wheels; and a support for the infant, wherein the chassis comprises first and second leg portions connected for relative pivotal movement between the folded and unfolded configurations, wherein the trolley further comprises a mount coupled to at least one of the first and second leg portions for pivotal movement relative thereto in either of two directions.

This allows the support (e.g. seat) mounted on the mount to fold towards the front or rear of the trolley when in use, as the mount can rotate/pivot in either direction relative to the leg/wheel.

In a preferred arrangement, the mount is coupled to at least one of the first and second leg portions by a floating hinge such that the mount is rotatable in both directions relative to the leg portions.

The mounts coupled to the first and second leg portions may accommodate mounts of an infant support, including a seat or a bed. The mount may comprise a lower mount on the undercarriage, which may have an upper mount.

In a preferred arrangement, the mount is coupled to the leg portions by hinge pins that engage a first slot in the first leg portion and a second slot in the second leg portion, whereby the slots constrain movement of the mount as the pins slide within the slots.

The mount may comprise a mounting portion for receiving a portion of the seat to mount the seat on the chassis.

Preferably, one or both of the first and second leg portions comprises a pair of spaced apart legs joined by a strut.

The hinge member may comprise a retaining arm arranged to engage one of the struts, or more preferably both struts, to limit the range of pivotal movement of the leg portion.

The stroller may include a handle portion, which may be integral with the chassis. Preferably, the handle portion is arranged for pivotal movement relative to one or both of the leg portions.

Preferably, the handle portion is foldable in two directions relative to the leg portion.

The handle portion may be arranged to engage at least one of the leg portions during the unfolding operation so as to cause relative pivoting of the leg portions away from each other. In a deployment operation, the handle portion and the leg portion may be engaged by sliding the pin in or along the track to a limit region beyond which the pin abuts against the abutment to effect relative pivotal movement upon further depression of the handle portion.

According to another aspect of the present invention there is provided a stroller comprising a chassis, a baby seat and a plurality of wheels, wherein at least one wheel is linked to the chassis by a wheel mounting member having a plurality of mounting portions for mounting the wheel such that the wheel is mountable on the chassis in a plurality of positions.

The wheel mounting member may have a plurality of mounting portions for mounting the brake member such that the brake member can be optimally positioned relative to the wheel.

Alternatively or additionally, the wheel may include one or more brake receiving portions for receiving a braking member to brake the wheel. The brake receiving portion may be located around the wheel and may be located at a radial distance from the center of the wheel so as to cooperate with the brake member.

The utility model also includes a method of mounting a seat on the undercarriage of a stroller, the method comprising: releasably mounting a lower portion of the seat to the lower mount; and releasably attaching an upper portion of the seat to the upper mount.

The method may include a method of installing a seat comprising a sheet material, such as fabric.

The utility model also includes a method of transitioning a stroller between a collapsed configuration and an expanded configuration, wherein the stroller has a chassis comprising first and second leg portions connected for relative pivotal movement between the collapsed and expanded configurations, wherein the stroller further comprises a mount coupled to the first and/or second leg portions for pivotal movement relative to the leg portions in either of two directions.

The coupling may be by a floating hinge such that the mount is rotatable in two directions relative to the leg portions, the method comprising limiting relative pivotal movement between the leg portions by engagement of the mount with the leg portions.

The utility model also includes a method of mounting a wheel on a stroller, the method comprising connecting the wheel to a chassis of the stroller by a wheel mounting member having a plurality of mounting portions for the wheel such that the wheel is mountable on the chassis in a plurality of positions.

The utility model may comprise any combination of features or limitations referred to herein, except combinations of features that are mutually exclusive or mutually contradictory.

Detailed Description

Referring to fig. 1, fig. 1 shows a stroller, generally at 100, including a chassis 120, a baby seat 130, a pair of front ground wheels 140a, a pair of rear ground wheels 140b, and a push handle 150. The seat 130 is detachable from the chassis 120, as described below.

Fig. 2 a-2 d illustrate the chassis 120 with the seat 130 in various different configurations. In fig. 2a, the seat is shown separately. In fig. 2b, a pair of seats is shown, facing each other and sharing a common mounting platform. In fig. 2c, the seat is shown in a rearward configuration on the chassis and in fig. 2d, the seat is shown in a forward configuration and tilted on the chassis.

Fig. 3a and 3b show an alternative seat 160, the seat 160 being detached from the chassis (fig. 3a), the seat 160 being attached (fig. 3 b). The seat 160 is a lightweight seat type made of a fabric material and mounted on the chassis in a lower portion and also in an upper portion, as described below.

Fig. 4 shows the flat bed 170 alone (fig. 4a) and the flat bed 170 mounted on the base frame (fig. 4 b).

The

seats

130, 160 and bed 170 may be removably mounted to the chassis by engaging mounting lugs 180 in lower mounts/members (not shown in these figures). In the case of seat 160, additional attachment is made at upper portion 190 located on handle 150.

For storing the trolley in, for example, a car, the trolley is fully foldable. Fig. 5a to 5d schematically show key stages in folding the trolley 100. The seat is omitted in each case for the sake of clarity.

Fig. 5a shows the trolley in a deployed configuration. The base frame 120 includes a pair of front legs 200 and a pair of rear legs 210. The front and rear legs are hinged together from side to side so that the front and rear legs can pivot relative to each other about point P.

In fig. 5b, the first latch (not shown) is released and the handle 150 is retracted down to a retracted position on the chassis 120. In fig. 5c, the second latch (not shown) is released and the handle 150 is folded forward over the front leg. In fig. 5d, the third latch (not shown) is released and the front and rear legs are pivoted towards each other, thereby placing the wheelbarrow in a fully collapsed configuration in which the wheelbarrow is locked using the fourth latch (not shown).

Fig. 6 shows the seat 160 partially attached to the chassis. The seat 160 is of the type consisting essentially of a sheet of material (most commonly fabric) and takes the form of a harness. The seat 160 is attached to the chassis at a lower attachment point and an upper attachment point.

In particular, the lower semi-rigid seat base 160a of the seat 160 is provided with two lower mounting lugs 220, the two lower mounting lugs 220 being removably located in the receptacles 230 of the lower mounting member 240. Additionally, at the upper seat back portion 160b, two upper mounting lugs 250 may be removably received in the slots 260 of the upper mounting member 270 on either side of the handle 150. In this figure, the fabric portion of the seat is shown in phantom for clarity. The upper portion 160b of the seat is not yet attached to the chassis.

Fig. 7 shows one of the upper lugs 250 positioned in the slot 260 of the upper mounting member.

To deploy the seat 160, the base 160a is first mounted on the lower mounting member 240, then the fabric back 160b is raised, and the upper lugs 250 are attached to the upper mounting member 270.

Fig. 8 shows one of the lower mounting members 240. The lower mounting member is located where the front leg and the rear leg are pivotally connected. The lower mounting member includes a central portion 240a and a pair of retaining arms 240b that engage front and

rear struts

280a, 280b when the undercarriage is fully deployed, the front struts 280a connecting the front legs 200 to one another and the rear struts 280b connecting the rear legs 210 to one another. The arms 240b limit the angle between the deployed legs.

The lower mounting member engages

legs

200 and 210 as a floating hinge, as described below. This allows the lower mounting member to pivot forward or rearward when the chassis is in the folded configuration, whereby the seat (not shown) can also be folded in either direction when mounted on the chassis.

Fig. 10 shows the undercarriage in a folded configuration, in which the

legs

200 and 210 pivot together and the lower mounting member pivots towards the front leg 200.

Fig. 11 shows only a portion of one half of the chassis with the strut 280 truncated. The lower mounting member pivots toward the rear leg.

Fig. 12 is a schematic exploded view showing the connection between one of the front legs 200, one of the rear legs 210, the handle 150 and the lower mounting member 240. Also, the

struts

280a and 280b are truncated.

The handle 150 is pivotally mounted with the front leg 200 and the rear leg 210 by a first pin 290 that passes through an aperture 300 in the connecting portion 310 of the handle 150, then through an aperture 320 in the connecting portion 330 of the front leg 200, and finally through an aperture 340 in the connecting portion 350 of the rear leg 210. The locking block LB locks the parts together.

The handle may be used to unfold the chassis from the folded configuration. This is achieved by pressing the handle in the direction of arrow a which causes the lugs L in the connecting portion 310 of the handle to slide in the holes 320 of the connecting portion 330 of the front leg until the lugs L abut the notches N in the holes 320, which then forces the legs to pivot apart.

Lower mounting member 240 is mounted for rotation about a second pin 360, which second pin 360 passes through a hole in lower mounting member 370 and into arcuate slots S1 and S2 in connecting

portions

350 and 330 of

legs

280b and 280a, respectively. This forms a floating hinge connection between the lower mounting member and the front and rear legs, with the pivoting of the lower mounting member being constrained by pins 360 in slots S1 and S2. The floating hinge is offset from the pivot axis between the front and rear legs and allows the lower mounting member (and any seat mounted therein) to pivot forward or rearward when the undercarriage is in the folded configuration. As

legs

200 and 210 pivot apart,

legs

200 and 210 reach their limits of movement when retaining arm 240b of the lower mounting member engages

posts

280a and 280 b.

Thus, the lower mounting member 240 is able to rotate/pivot in either direction relative to the legs/wheels, allowing a support (e.g., a seat) mounted on the lower mounting member 240 to fold forward or backward in use.

FIG. 13 shows the second pin 360 positioned in slots S1 and S2.

Fig. 14 shows a second embodiment of a lower mounting member 240'. In this embodiment, mounting member 240' has a fixed pivot axis P relative to

legs

200 and 210. When the mounting member is pivoted in the direction of arrow B in the drawings, a pair of spring-loaded locking pins LP enter the respective leg-receiving receptacles LS, and thus the mounting member 240' is locked in position relative to the legs.

Also, the lower mounting member 240 'can rotate/pivot in either direction relative to the legs/wheels, allowing a support (e.g., a seat) mounted on the lower mounting member 240' to fold forward or backward in use.

Referring to fig. 15, fig. 15 shows one of the wheels 140 of the cart. The wheel 140 is connected to the leg 210 by a wheel mounting member 380, the wheel mounting member 380 itself being fixed to the leg 210. The wheel mounting member 380 has a plurality of mounting holes 390 for receiving a rotatable spindle (not shown) of the wheel 140. The mounting holes 390 are spaced apart at locations around the wheel mounting member 380 so that the wheel 140 can be accommodated at different locations on the wheel mounting member.

This means that the cart may use wheels of different sizes, which may be useful on different terrains. In addition, different positions of the wheels may change the effective wheelbase of the cart, which may aid in stability.

Referring to fig. 16a to 16c, fig. 16a to 16c show the wheel 140 mounted on the wheel mounting member 380. The mounting holes 390 may also be used to attach a brake member 400, the brake member 400 acting on the wheel to prevent rotation of the wheel. The brake members are actuated by one or more levers or cables (not shown). By selecting a suitable mounting hole, the brake member can be optimally positioned relative to the wheel, depending on the size and position of the wheel. In the illustrative example, only three such apertures are shown. However, there may be more or fewer mounting holes.

Referring to fig. 17, fig. 17 schematically illustrates an alternative embodiment of a wheel mounting member 380 ', the wheel mounting member 380' being located at the base of each of at least the rear legs (not shown) of the cart.

The wheel mounting member 380' includes a plastic body 382 having an integrally formed axle bore 384 for mounting the axle of a pair of wheels (not shown) in one of a plurality of positions. Each position allows the cart to accommodate wheels of different diameters and allows for different wheelbases. In this example, the brake member 400 'is in the form of a pin, the brake member 400' being located within a brake member housing 402 and being axially movable by actuation of a brake lever 404 and releasable by actuation of a brake release button (not shown). Alternatively, the actuation and release controls may be provided according to an alternative arrangement (not shown).

Fig. 18 shows a wheel 140 for mounting on the wheel mounting member 380' of fig. 17. The wheel includes a hub 142, spokes 144, a rim 146 with a tire 146a, and a brake engagement portion 148, the brake engagement portion 148 including a plurality of receptacles 148a for receiving the brake members 400' when axially displaced. The radial spacing of the receptacles 148a is selected to correspond to the wheel diameter based on the distance between the axle bore and the brake member, whereby the receptacles can receive the brake member 400' regardless of which axle bore is in use.

The chassis and/or wheels may be of any suitable material, such as, but not limited to, metal (e.g., steel, aluminum/alloy) or plastic. The support/seat/bed may be a combination of plastic and fabric. The mount may be plastic or metal.

Embodiments of the pushchair according to the present invention allow for multiple versions of the pushchair to be produced from a common single chassis. In particular, the lower fixture/mount provides an attachment point for the movable seat, and when combined with the lower fixture, the upper attachment/fixture connected to the handle allows for a "fabric harness" to be easily attached.

Furthermore, the folding mechanism, for example using a floating hinge, allows the lower mounting member (attachment system) to fold with the chassis, making it more compact for storage, and also makes the cart self-supporting/free of supports when in the folded configuration.

The wheel mounting arrangement allows for the use of different sized wheels.

This results in a trolley system that allows multiple seat/infant support configurations to be attached to and detached from the chassis/frame. The lower mount allows all seats to be directly attached to the frame. This connection is common to all seats.

A second attachment point at the upper portion of the chassis/handle facilitates attachment of a soft strap that attaches to the handle and provides support for the upper portion of the seat to form the side of the seat through which the backrest may be supported.

The respective fasteners are attached to the sides of the fabric harness, which allows the harness system to be quickly and easily removed from the frame and allows different seats to be attached in its place.

The mount may be varied in design to allow the lateral dimensions of the seat to be varied.

The lower mounting member/anchor is driven by the frame and is supported when in its deployed position, thereby preventing the seat from collapsing.

When folded, the two leg portions (support members) articulate about a central pivot point, allowing the lower mounting member (attachment) to rotate forward or backward into the frame/chassis.

This allows any seat connected to the lower mounting member/attachment to rest in a position perpendicular to the respective leg portion (frame member).

The pivot point of the lower mounting member (attachment) is offset from the hinge point of the leg/frame member, but rotates about the virtual axis of the leg/frame member when folded.

When deployed and in use, the concentric grooves fix the pivot point of the lower mounting member/attachment in a constrained position.

The trolley frame also comprises a rear configuration which allows, for example, to attach wheels of different diameters, in particular at the rear.

The rear rail system allows the assembly to be moved to various positions, allowing different wheel diameters to be attached to the frame without affecting the geometry of the cart.

Referring to fig. 19a and 19b, fig. 19a and 19b schematically illustrate an alternative embodiment of the seat 1160 shown in fig. 6 and 7 in a side view and a front view, respectively, for use with the cart 100 described herein. The seat 1160 is mounted to the chassis 120 of the cart in two locations. First, there is a lower semi-rigid base 1160a that is removably attached to the chassis in substantially the same lug and socket arrangement as the embodiment of fig. 6. However, the seat 1160 also has a pair of tubes 1170, one of the pair of tubes 1170 being located on one side of the seat 1160 and serving as a support for the fabric back of the chair by passing through sleeves in the fabric back of the chair (not shown). The tube 1170 itself is telescopically/slidably mounted in a mounting bracket 1180, the mounting brackets 1180 being pivotally attached on each side of the handle 150. Tube 1170 is pivotally connected to base 1160 a.

Fig. 20a and 20b show the trolley folded towards the front of the handle 150 in the direction of arrow C. As the handle 150 is pivotally folded over the chassis, the tube 1170 is also pivoted relative to the base 1160 a. Thus, they are able to slide within the bracket 1180 to accommodate displacement due to the space between the respective pivots.

Fig. 21 is a more detailed view of the rack 1180 showing a portion of the tube 1170 in the rack 1180. The bracket 1180 is generally tubular and has a channel portion 1182 on an outer surface for receiving a ledge 1184 (not shown in this view) of the handle 150. The slot 1182 has a T-shaped profile for capturing and retaining a complementary shaped tab 1184, the slot 1182 being slidably engageable with the tab 1184 when the seat is engaged and disengaged with the chassis 120.

Whilst endeavoring in the foregoing specification to draw attention to those features of the utility model believed to be of particular importance it should be understood that the applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
