Definitions

  • This invention relates to a stroller or baby carriage with controlled steering wheels that make the stroller or baby carriage more easily steerable.
  • strollers or baby carriages have essentially two types of drive, i.e. with fixed wheels in which change of direction takes place by pressing on the handle bar to raise the front wheels and allow turning the vehicle by hinge pinning on the rear wheels, and with pivoting wheels in which change of direction takes place by applying steering torque with the arms, that is by holding back the carriage by one part of the pushing bar and pushing on the opposite side thereof.
  • Both solutions require physical effort. In the case of strollers or baby carriages of the twin type, the effort is still greater and guidance more difficult.
  • the general purpose of this invention is to remedy the above mentioned shortcomings by making available a stroller or baby carriage in which direction is controlled by means of an active steering device.
  • a stroller or baby carriage device including a supporting frame for a member receiving one or more children, a pushing bar and front and rear wheel pairs and characterized in that a pair of wheels is made steering and controlled by a steering wheel device arranged on said bar.
  • FIG 1 shows a diagrammatic perspective view of a frame for a stroller or baby carriage realized in accordance with the principles of this invention
  • FIG 2 shows a diagrammatic perspective view of the steering mechanism controlled by the wheels of the frame of FIG 1
  • FIG 3 shows a diagrammatic perspective view of the steering wheel or handle bar of the frame of FIG 1.
  • FIG 1 shows diagrammatically a carriage designated as a whole by reference number 10 having a frame 11 supporting a known child-containment member 12 (in broken lines) which depending on use can be a baby's chair for realizing a stroller or a small passenger compartment for realizing a baby carriage.
  • a known child-containment member 12 in broken lines which depending on use can be a baby's chair for realizing a stroller or a small passenger compartment for realizing a baby carriage.
  • the carriage with the containment member can be adapted to the transport of one or more babies as easily imaginable to those skilled in the art.
  • a stroller for two babies is diagrammed in the figures.
  • the vehicle has a push bar 13 appropriately positioned and four wheels of relatively large diameter.
  • the two rear wheels 14 are keyed to a single axis 15 arranged normal to the line of march.
  • the two front wheels 16 are keyed to respective axle shafts each hinged in accordance with the respective vertical axis 17 so as to form steering-wheel units 21 around axes perpendicular to the ground.
  • the wheel units 21 are connected together by means of a tie rod 18 so as to have synchronous parallelogram movement.
  • FIG 2 shows in greater detail the kinematics for steering the front wheels.
  • each wheel unit includes an L-shaped arm 22 hinged on the steering axis 17 and realizing the parallelogram transmission for the tie rod 18.
  • the hinging points 23 of the tie rod 18 are at a certain distance h2 from the axis of the hinge 17 hinging the wheel units to the frame so as to form the parallelogram kinematics.
  • an appropriate elastic rebound element 24 can be inserted close to the steering tie-rod.
  • Said member 24 includes two springs for returning to the rectilinear running position. With a damping effect, said springs draw apart to have a balance point with the wheels in straight- line running position and have the purpose of making the steering smoother and less sensitive to favor greater comfort for the occupant of the stroller.
  • Two flexible control cables 25 running along or in the frame to the steering wheel 19 reach the tie rod 18 from opposite directions.
  • FIG 3 shows a detail of the steering wheel keyed and free to rotate around the axis 20 however oriented.
  • the two cables 25 that transmit to the kinematic mechanism of the wheels a traction generated by rotation of the steering wheel by means of a lever 26 integral with the steering wheel and with arm hi are connected to the steering wheel.
  • an appropriate locking push-button 27 allows locking of handlebar rotation so as to be able to lock the steering wheels aligned with the axis of the vehicle in case of special requirements, for example steering with only one hand or on rough ground.
  • the relationship between hi and h2 defines the steering relationship between the angle ⁇ of the steering wheel and the angle ⁇ of the wheels.
