Definitions

  • This invention relates to a collapsible pushchair for infants otherwise known as a baby buggy or stroller and more particularly to a pushchair which can be easily collapsed for storage or transportation when not in use.
  • the invention relates to a puschair that can be collapsed to a size which is extremely compact and acceptable as carry-on luggage on an aeroplane.
  • Collapsible pushchairs are well known. Generally these have a number of tubular frame members to which a seat is attached. Braces extend between and are pivotally attached to the frame members so as to support the frame members and control the folding process. Often, the members or braces are pivotally connected to each other so that the pushchair will fold in a generally scissor like fashion with the frame members and braces folding onto or against each other so that the pushchair assumes a more compact configuration suitable for storage when not in use.
  • a problem with known pushchairs is that they generally have a complicated construction and are difficult to collapse and open ready for use.
  • the arrangement of pivots and braces that provides the mechanism that allows the pushchair to fold is complex and makes the pushchair difficult and expensive to manufacture.
  • the folding mechanism also presents a number of opportunities for fingers to become trapped between tubular members or braces during the folding procedure resulting in injury.
  • a collapsible pushchair comprising a chassis to which wheels are attached, a pair of spaced parallel tubular body portions fixed relative to and extending upwardly from the chassis away from the wheels on opposite sides of a seat, a first handle part received in each tubular body portion and slideable between an extended position in which the first handle part primarily extends from an upper end of the tubular body portion towards a person pushing the pushchair and, a second position in which the first handle part has been slid through each tubular body portion so that the first handle part extends from the upper end and a lower end of each of the tubular body portions.
  • tubular body portions and the first handle part are configured such that substantially the same length of the first handle part protrudes from the upper and lower ends of each tubular body portion when the first handle part is in its second stowed position.
  • the tubular body portions and the first handle part may be configured such that, when the first handle part has been slid through each of its tubular body portions into its stowed position, the pushchair can be moved into an upright position in which it is supported on said wheels and the first handle part protruding from the lower end of the tubular body portions.
  • the lower ends of the first handle part are received within their corresponding tubular body portions when the first handle part is in its extended position.
  • the lower ends of the first handle part may protrude from the lower end of each of the tubular body portions when the first handle part is in its extended position. Preferably, only a very small length of the first handle part protrudes from the lower end of the tubular body portions.
  • caps or abutment members are attached to the lower ends of the first handle part to prevent the first handle part from being pulled through the tubular body portions when the first handle part is extended.
  • the end caps comprise feet to support the pushchair in an upright position when the first handle part is in its stowed position.
  • the pushchair comprises a locking mechanism to lock the first handle part in its extended and stowed positions within the tubular body portions.
  • the pushchair comprises a second handle part, the second handle part being slideable between a first position in which it extends upwardly from an end of the first handle part towards a person pushing the pushchair and a retracted position in which it is received within the first handle part.
  • the first handle part can comprise a separate tubular member received in each tubular body portion and the second handle part comprises a U- shaped frame member that extends from the upper end of each of the separate tubular members and connects them together so that, when the second handle part is retracted within the separate tubular members, further downward force on the second handle part simultaneously pushes both separate tubular members through their respective tubular body portions so that the first handle part is moved from its extended toward its retracted position.
  • the wheels comprise a primary wheel attached to the chassis adjacent to the lower end of each of the tubular body portions.
  • the pushchair advantageously also comprises a pair of secondary wheels located behind the primary wheels and stowable between the primary wheels when the pushchair is collapsed.
  • a pair of parallel arms extends from the chassis, a secondary wheel being connected to each of said arms.
  • Each of said arms may be pivotally mounted to the chassis and comprise two portions pivotally connected to - A -
  • each arm pivots relative to the chassis and the two portions pivot relative to each other when the secondary wheels are moved into their stowed position between the primary wheels.
  • a stay extends between each of the secondary wheels and the upper end of the tubular body portion.
  • the stay is pivotally attached to the tubular body portion such that the stay pivots relative to the tubular body portion when the secondary wheels are moved into their stowed position between the primary wheels.
  • the pivotal attachment of the stay to the tubular body portion is spaced from the tubular body portion in a direction towards the secondary wheels to provide a space between the tubular body portion and the stay to receive the arms when the secondary wheels are received in their stowed position between the primary wheels.
  • a flexible seat hanger preferably extends between each of the tubular body portions and the stays.
  • a method of collapsing a collapsible pushchair comprising a chassis to which wheels are attached, a pair of spaced parallel tubular body portions fixed relative to and extending upwardly at an angle from the chassis away from the wheels on opposite sides of a seat and a first handle part received in each tubular body portion, the method including the step of sliding the first handle part into the tubular body portion from a first extended position in which it primarily extends from an upper end of the tubular body portion towards a person pushing the pushchair, into a second stowed position in which the first handle part extends from the upper end and a lower end of each of the tubular body portions.
  • the method of the invention preferably also includes the step of sliding the second handle portion into the first handle portion prior to sliding the first handle portion into the tubular body portion.
  • the chassis may be moulded from any suitable rigid plastics material such as mineral filled polypropylene.
  • the secondary wheels are retained in their stored position in the chassis by means of a releasable latch mechanism.
  • the means which connect the secondary wheels to the chassis operate so that said wheels automatically unfold from the chassis under the action of gravity when the releasable latch mechanism retaining them in the chassis in their stowed position is released.

  • the lower end 13 of each tubular body portion 6,7 is connected to a generally tubular and similar sized portion of the chassis 2 on each side 3,4 which is also open at its lower end 14 so that each tubular body portion 6,7 together with its respective chassis side 3,4 to which it is attached has a longitudinal passage extending all the way through it.
  • first handle portion 15 comprising separate elongate tubular members 16, 17 are slideably received in each of the tubular body portions 6, 7.
  • first handle portion 15 is shown in its first or extended position in which each of the elongate tubular members 16, 17 of the first handle portion 15 extend primarily or wholly from the upper end 12 of their corresponding tubular body portions 6, 7. In this position, the lower end of each of the tubular members 16, 17 are received within the tubular portion of the chassis 2 and are prevented from being pulled all the way through the tubular body portions 6,7.
  • abutments or caps 18 are provided on the lower end of each tubular member 16, 17 which contact or engage with the chassis 2 when the first handle portion 15 is in its extended position so as to prevent the tubular members 16, 17 from being pulled through the tubular body portions 6, 7 and separated from the pushchair 1, as the diameter of the caps 18 is greater than the diameter of the aperture in the chassis sides 3,4.
  • the diameter of the caps 18 is greater than the diameter of the aperture in the tubular body portions 6,7 but less than the diameter of the aperture in the chassis sides 3,4 so that the end caps 18 are received within or partially or wholly enclosed by the chassis sides 3,4 when the first handle portion 15 is fully extended.
  • a second handle part 19 extends from the upper end of each of the tubular members 16,17.

  • the second handle part 19 is U-shaped so that each of the elongate members 20,21 are connected together by a cross-member 22 which also forms the handle of the pushchair to enable it to be grasped by a user and pushed, or pulled, along.
  • a locking mechanism 23 locks the second handle part 19 to the first handle part 15 in its extended position.
  • This locking mechanism 23 may take any convenient form but could, for example, comprise a sprung pin in each of the elongate members 20,21 of the second handle part 19 that engages in a corresponding aperture in each of the tubular members 16,17 of the first handle part 15 and which can be easily released by a user to enable the pushchair 1 to be collapsed.
