Definitions

  • the invention relates to a buggy.
  • a buggy is defined as a pushchair for transporting children.
  • a buggy typically has an undercarriage with wheels, a sitting and/or reclining part for a child and a handle for handling the buggy.
  • a buggy is often used when an adult moves around with a child, regardless of the context such as going to a shop, going for a walk, visiting an amusement park, visiting family, and so on.
  • the buggy is provided with a sitting and/or reclining part in which the child can be placed and can typically be secured.
  • the buggy is convenient fortransporting objects which may or may not be related to childcare.
  • Buggies are commercially available in many forms, sizes and colours and can typically be collapsed so as to be stored and transported compactly. The majority of buggies is additionally designed to strike a good balance between compact, convenient and inexpensive.
  • the object of the invention is to provide a buggy which is optimized for shared use.
  • a further object of the invention is to provide a buggy which is optimized to be rented out.
  • the invention provides for this purpose a buggy comprising an undercarriage and a bucket, wherein the bucket is formed as a seat for a child, characterized in that the undercarriage comprises a rigid frame and that the bucket is integrally formed from an EPP material and is mounted fixedly onto the undercarriage.
  • a rigid frame with an EPP bucket thereon can be manufactured, assembled, maintained and cleaned in very simple manner. These are all significant conditions for enabling shared use.
  • a rigid frame with an EPP bucket thereon is further weather-resistant.
  • a further advantage is that EPP is an insulating material, such that the EPP does not feel cold and does not absorb moisture, even when it has been in a cold and humid environment for a long time. This allows the buggy to be left outside, for instance in a parking facility of a public or private area frequented by people with children, this making the buggy suitable for rental.
  • An EPP bucket is simultaneously strong and comfortable.
  • the bucket preferably has on either side a strengthening beam which extends over the whole length of the bucket.
  • a strong EPP bucket can de formed, which can be mounted on the rigid frame in simple manner.
  • the strengthening beams can be curved so that the distance between the strengthening beams is smaller at the top and at the bottom than in the middle.
  • the strengthening beams preferably run parallel to carriers of the rigid frame so that the bucket rests with the strengthening beams on these carriers.
  • the carriers preferably have substantially the same curvature as the strengthening beams.
  • Connections are preferably further provided to connect the strengthening beams to the rigid frame.
  • the front side of the bucket preferably extends substantially in 1 plane. On one hand, this provides for an aesthetic design and, on the other, this facilitates the production process. EPP is formed in a mould. Providing a mould for a bucket wherein the front side of the bucket extends in 1 plane is considerably simpler and reduces the complexity and, with this, the cost price of the mould.
  • the bucket preferably has an upper segment with a seat part and a lower segment with a footrest. Integrally forming the seat part and the footrest simplifies the production process of the buggy.
  • the bucket preferably has an opening between the footrest and the seat part. More preferably, the footrest and the seat part of the bucket are formed by beam-like connections between the strengthening beams, which beam-like connections preferably extend parallel.
  • the seat part is further connected to a backrest which extends upward from the seat part as a bucket between the strengthening beams. Manufacturing both the seat part, the footrest and the backrest integrally from EPP improves both the comfort for the child and the use and maintenance of the buggy.
  • the frame preferably connects a set of wheels to a support for the bucket, wherein the frame further has a handle for handling the buggy.
  • the set of wheels is further preferably connected to a U-shaped of V-shaped frame part, wherein a rear set of fixed wheels are connected to ends of the legs of the U-shaped or V-shaped frame part, and wherein a front set of swivel wheels are further connected to the U-shaped or V-shaped frame part, wherein the transverse distance between the front set of swivel wheels is smaller than the transverse distance between the rear set of wheels so that the front set of swivel wheels of a first buggy fits between a rear set of fixed wheels of a second buggy.
  • the front set of swivel wheels can consist of one or more swivel wheels.
  • the buggy can thus be formed with one central swivelling front wheel, or the buggy can be formed with two front wheels which are placed adjacently of each other and which both swivel.
  • Making the frame U-shaped or V-shaped, connecting the rear wheels to the outer ends of the legs of the U-shape or V-shape and making the front of the frame narrower than the rear enables the front wheels of a first buggy to be pushed between the rear wheels of a second buggy, and enables a plurality of buggies to be pushed partially together. This facilitates orderly storage of a plurality of buggies in for instance a parking facility, which is important for shared use and for rental.
  • a luggage carrier is preferably provided inside the U-shaped or V-shaped frame, which luggage carrier is connected pivotally to the frame at the position of the front set of swivel wheels and which luggage carrier is supported loosely by the frame at the position of the rear set of fixed wheels.
  • a luggage carrier greatly increases the convenience of use of the buggy. More specifically, the luggage carrier will enable efficient use of the space underneath the seat.
  • the luggage carrier can be formed by a plastic plate or plastic tray which fits in the U-shaped or V- shaped frame.
  • the plastic plate or plastic tray can optionally have a bottom formed by a mesh or net.
  • the luggage carrier preferably has a ride-on board extending between the rear set of wheels and provided to rest on the legs of the U-shaped or V-shaped frame part on either side.
  • the ride-on board provides for increased convenience of use and improves the strength of the buggy.
  • the rear wheels preferably have a brake mechanism which makes mechanical contact with the luggage carrier when in its lowermost position in order to uncouple the brake mechanism, wherein the brake mechanism brakes when the luggage carrier is in upward pivoted position. Uncoupling the brake when the luggage carrier is brought into the lowermost position automatically brings the buggy into a mode of use. Conversely, the buggy will remain firmly in place by energizing the brake when the luggage carrier is pushed upward. This increases the convenience of use and increases the ease of pushing the one buggy into the other buggy.
  • the frame is preferably provided with a sun hood which extends at least partially over the bucket.
  • the sun hood further preferably has a viewing panel so that an adult located behind the buggy, at the handle, can see the child in the buggy through the viewing panel.
  • the viewing panel can be made of a transparent plastic or can be formed by an opening in the sun hood.
  • the sun hood also forms a protection against rain, snow and wind.
  • the sun hood is preferably provided fixedly on the frame.
  • the sun hood can be made of a hard plastic or of metal.
  • the frame preferably comprises an identification mechanism, position detection mechanism, a digital communication mechanism and output mechanism chosen from an auditive, visual and tactile mechanism, such that use by end users of the buggy is digitally manageable by an owner.
  • User management by an owner of a plurality of buggies is possible via a digital backend system.
  • This backend system collects the locations of the buggies. Via this backend system end users can register use of a buggy and the owner can charge for this use. A user can be informed about correct and/or incorrect use of the buggy via the output mechanism.
  • the identification mechanism for instance a QR code, barcode, NFC chip or similar means, allows every buggy to be uniquely identified and allows feedback to a backend system.
  • the position detection mechanism allows intensity of use of roads, passageways and other infrastructure to be measured. Road and junction activity can also be measured, so that infrastructure can be improved in targeted manner. In other words, frequently used roads, passageways and junctions can be expanded or optimized for frequent use in other ways.
  • the frame further preferably comprises at least one of vibration sensors and motion sensors. It is particularly in combination with a position detection mechanism that these vibration and/or motion sensors allow the condition of a ground surface to be measured. This can be interesting and valuable information for cities, parks, companies or other organizations responsible for maintenance and/or interested in infrastructure quality. Information about vibrations and motions, measured in the buggy, is further indicative of the intensity of use and therefore also of wear on the buggy. This information therefore allows proactive maintenance and repairs to be carried out. This minimizes failure and enables the return of the buggy to be optimized further.

  • figure 2 shows a bucket of the preferred embodiment of figure 1
  • figure 3 shows an undercarriage of the preferred embodiment of figure 1
  • figure 4 shows that two buggies according to the invention can be stacked horizontally
  • figure 5 shows a snap mechanism suitable for connecting a bucket to an undercarriage
  • figure 6 shows a connecting mechanism suitable for connecting parts of an undercarriage to each other.
  • the same or similar elements are designated in the drawing with the same reference numerals.
  • FIG. 1 shows a buggy 1.
  • the buggy 1 has an undercarriage 2 and a bucket 3.
  • the bucket 3 is mounted fixedly on the undercarriage 2.
  • a sun hood 4 is further mounted fixedly on undercarriage 2 in order to cover at least a part of bucket 3.
  • a viewing panel 21 of a transparent plastic can be provided in sun hood 4, preferably in the centre at the top. Alternatively, the viewing panel 21 can be formed in sun hood 4 as an opening.
  • sun hood 4 describes just one possible function of the hood in question, and that sun hood 4 also has other functions such as protection against rain, wind, snow and other external influences.
  • the term sun hood 4 is therefore not limitative, and any hood which protects against the sun when necessary, even if it were to have a different primary purpose, will be deemed a sun hood 4.
  • Undercarriage 2 extends upward and has a handle 5 so that the buggy can be handled by a person.
  • Undercarriage 2 is provided with two front swivel wheels 6. One centrally positioned front swivel wheel can also be provided as alternative.
  • Undercarriage 2 is further provided with two rear wheels 7.
  • the rear wheels 7 are fixedly connected to undercarriage 2 via a rotation shaft which allows for normal rotation of the wheels 7.
  • Undercarriage 2 is provided to support bucket 3.
  • Uuggage carrier 8 is preferably formed as a hard plastic tray, at least a portion of the edges of which fit onto the frame of undercarriage 2 so as to rest thereon.
  • Bucket 3 is formed integrally from EPP, expanded polypropylene, which is a polypropylene-based particle foam. Bucket 3 has an upper segment with a seat part 11 and a backrest 12. Bucket 3 further has a lower segment with a footrest 10. Bucket 3 has a strengthening beam 9 on both sides. The strengthening beams impart resistance against bending to bucket 3. The strengthening beams 9 are further provided to rest on corresponding support beams of undercarriage 2 and so determine the position of bucket 3 relative to undercarriage 2.
  • strengthening beams 9 extend from the top to the bottom of bucket 3, and because strengthening beams 9 rest over substantially the whole length on undercarriage 2, forces engaging on bucket 3 and weight located in bucket 3 are distributed over a large contact surface between bucket 3 and undercarriage 2, so that peak forces or point forces that could break bucket 3 can be avoided.
  • Footrest 10 is formed by a beam which connects strengthening beams 9 to each other on the lower side of bucket 3.
  • Seat part 11 is formed by a beam which connects strengthening beams 9 to each other in a central zone of bucket 3.
  • Beam -like seat part 11 preferably extends in the same direction as footrest 10 in order to facilitate removal of bucket 3 from a mould in one piece.
  • Front side of bucket 3, formed by strengthening beams 9, seat part 11 and footrest 10, preferably extends in one plane. This also facilitates manufacture in a mould.
  • the bucket is open 13 between seat part 11 and footrest 10.
  • bucket 3 has a backrest 12 which extends upward and on the rear side of the seat part between the two strengthening beams 9 so as to serve as support for the back of a child.
  • Seat part 11 and backrest 12 preferably have an ergonomic design.
  • a belt is preferably provided in order to secure a child in the buggy.
  • the belt serves here to prevent a child from falling out of the buggy. This principle is known and will therefore not be further elucidated in this description.

  • Bucket 3 is formed integrally from EPP.
  • Strengthening beams 9 extend substantially wholly from top to bottom, have a width of at least 30 mm, preferably at least 40 mm, more preferably at least 50 mm. In the lower segment the strengthening beams 9 have a height, measured perpendicularly of the frontal plane, of at least 60 mm, preferably at least 80 mm, more preferably at least 100 mm. In the upper segment the strengthening beams 9 have a height, measured perpendicularly of the frontal plane, of at least 80 mm, preferably at least 100 mm, more preferably at least 120 mm. In mounted state the strengthening beams 9 extend upward at an angle of between 45 degrees and 80 degrees relative to the horizontal direction, preferably between 55 degrees and 70 degrees.
  • Footrest 10 connects strengthening beams 9 on a lower side.
  • the beam-like footrest In mounted state the beam-like footrest is substantially flat and substantially horizontal at the top.
  • the footrest has a thickness, measured in upward direction, of at least 20 mm, preferably at least 30 mm, more preferably at least 40 mm, and has a thickness, measured in horizontal direction, of at least 60 mm, preferably at least 80 mm, more preferably at least 100 mm.
