Children are commonly transported in pushchairs or buggies. For many purposes, such transporters are perfectly adequate but they can be bulky and are not easily manoeuvrable. They can be difficult to navigate through small gaps, into small spaces or crowded areas, or to lift over obstacles. Moreover, these transporters do not perform well when pushed at speed or over rough ground, resulting in an uncomfortable ride for the child and, in some circumstances, causing damage to the pushchair or buggy.
It is becoming desirable to include children in physical activities such as jogging, running or hill-walking. However, the physical weight of a child of more than a few months old can preclude the possibility of the child being carried in a sling or backpack-type carrier during such activities. If the child is not carried, the lack of physical strength of the child may prevent the activity from being continued for as long as is desired by the child's parent, carer or guardian.
There is a need for a lightweight, portable, child transporter which can be used to transport a child over rough ground and/or at speed so that the child can participate in activities such as jogging, running or hill-walking undertaken by the child's parent, carer or guardian. There is also a need for a child transporter which is controllable and highly manoeuvrable by an adult walking or running over rough terrain so that the child can accompany the adult during such activities without needing to be carried. Ideally, the transporter itself needs to be transportable.
Child transporters have been proposed in the past. Examples are shown in DE 296 03 016 U1, DE 85 27 278 U1, EP 1 582 433 A1 and U.S. Pat. No. 5,511,802. However, in all of these prior art documents, the child transporter carries the child in such a way that the child's weight is borne, at least in part, by the child's parent, carer or guardian. This makes the child transporter more arduous to use than it need be. If the child transporter is arduous to use, the parent, carer or guardian may be reluctant to use the child transporter or, when he or she does use it, may not push the child transporter as far or as fast as the child would like to go.
The present application describes a child transporter comprising a wheel having an axle, a seat located directly above the wheel for supporting the child, at least one footrest for supporting the child's feet such that, in use, the child straddles the wheel, and a handle extending away from the wheel so as to be graspable by an adult. Preferably, the wheel forms the only point of contact with the ground when the child transporter is in use. This arrangement allows the child to sit astride the single wheel, but with the accompanying adult controlling the speed of forward movement, the balance and the steering of the transporter. The child's centre of gravity is positioned directly over the wheel, ideally passing substantially through the axle of the wheel, so that the force required to steer and balance the child transporter is minimised. At walking speed, the adult is able to steer and balance the transporter. At jogging speed, the gyroscopic effect of the rotating wheel keeps the wheel upright and the adult needs only to steer the transporter. The transporter is therefore highly manoeuvrable and controllable by the adult which makes the transporter suitable for use over rough terrain and at speed. Allowing the weight of the child to be carried by a suitable transporter means that the adult can take part in physical activities without carrying the child, which in turn allows the adult to be physically active for longer whilst maintaining appropriate supervision and control of the child. Such a transporter is also suitable for use in crowded areas such as towns or shops.
In some embodiments, the handle is collapsible and/or foldable and, more preferably, the handle forms a carrying handle for the child transporter when the handle is in a collapsed or folded position. This makes transportation and storage of the child transporter easier and more convenient than would be the case with a fixed handle.
In some embodiments, the child transporter includes at least one stabilising wheel connected to the handle such that, in use, movement of the handle in a direction perpendicular to the ground determines whether or not the at least one stabilising wheel contacts the ground. This allows the adult the option of using the stabilising wheel or wheels to make it easier to control the child transporter at lower speeds, particularly when travelling over smooth surfaces such as roads or pavements. The additional stability provided by the stabiliser wheel or wheels decreases the amount of effort required to maintain the child transporter in an upright position, particularly if the child being transported moves his or her weight from side to side.
Further preferred and advantageous features will be explained and become apparent with reference to the following specific embodiments of the disclosed child transporter, in which:
The child transporter 10 shown in
The seat assembly 14 also comprises a seat 28 which is provided on and supported by the frame 16. The seat 28 comprises a seat portion 30 and two side panels 32. The seat portion 30 extends across the wheel 12 so that the seat portion 30 projects beyond the extremities of the wheel 12 on either side thereof The seat portion 30 extends between the second U-shaped portion 20 and the handgrip 26 and is shaped so as to allow a child to sit comfortably thereon whilst allowing the wheel 12 to rotate beneath it. The shape of the seat portion 30 is contoured so that, if a younger child is seated on the child transporter (10), the child can comfortably sit in a forward position whilst, if an older child is to be transported, that child can sit further back on the seat portion (30). The side panels 32 extend downwardly from the seat portion 30 towards the first side portions 22, extending forwardly as far as the first U-shaped portion 18. The side panels 32 are generally planar to ensure that rotation of the wheel 12 is not inhibited.
Footrests 34 are provided on the seat assembly 14. The footrests 34 extend outwardly from the side panels 32, again without interfering with the rotation of the wheel 12. In the embodiment shown in
A handle 36 extends rearwardly from the seat assembly 14 and includes a longitudinal portion 38 and a transverse portion 40. The length of the longitudinal portion 38 is such that, when the child transporter 10 is in use, the transverse portion 40 is conveniently graspable by an adult so that the child transporter 10 can be pushed along the ground. In the embodiment shown, the transverse portion 40 is located approximately 1100 mm from the central axis of the wheel 12, although this distance can be varied between 990 mm and 1300 mm depending upon the height of the adult who will be using the child transporter 10 to transport a child. The transverse portion 40 extends to either side of the longitudinal portion 38 and is appropriately shaped to allow the transverse portion 40 to be grasped with both hands by an adult.
The longitudinal portion 38 of the handle 36 is constructed so that the handle 36 can be rotated with respect to the seat assembly 14 and collapsed so as to facilitate transport and storage. In the embodiment shown in
The wheel 12 shown in
As mentioned above, the footrests 34 are adjustable so that they can be positioned in any one of a number of different positions (for example, three) with respect to the seat portion 30. In the embodiment shown in
The child transporter 10 shown in
The child to be carried is then allowed to sit on the seat portion 30. The child grasps the handgrip 26 and places his or her feet on the footrests 34. The position of the child is such that the child straddles the wheel 12 with his or her bottom sitting on the seat portion 30 and his or her legs positioned on either side thereof outside the side panels 32. The side panels 32 prevent the child's legs, feet or clothing from coming into contact with the wheel 12. The arrangement just described is illustrated in
It is also possible for the adult to push the child transporter 10 forwards at a pace which is faster than walking pace. Jogging or running paces are easily possible. As the speed of rotation of the wheel 12 increases, so does the gyroscopic effect tending to keep the wheel 12 in an upright orientation. This reduces the force needed to be applied by the adult to overcome any tipping forces and thus allows the adult to release one hand from the transverse portion 40 if desired. The remaining hand is moved to the centre of the transverse portion 40. This ensures that the adult remains in control of the push force being applied to the child transporter 10 and any steering which is required. With only one hand being needed for effective control of the child transporter 10, the adult is free to perform extensive periods of jogging or running over rough terrain whilst maintaining appropriate control and supervision of the child.
The child transported of the present application is not limited to the embodiment described in detail above. Various changes and alterations can be made without departing from the scope of the invention. For example, the shape of the distal end of the handle 36 can be varied in many different ways, some examples of which are shown in

Another feature of the child transporter 10 shown in
Finally,
Any and all of the arrangements described above would be advantageous from the point of view of allowing the child transporter described above to be stored and transported conveniently.
A further aspect of the child transporter 10 described in relation to
Keeping the child's arms and hands close to the central axis minimises the ability of the child to apply a tipping force to the transporter, which must be countered by the adult making use of the transporter. Other than that, none of the handgrips 26a, 26b, 26c, 26d shown in
It is not necessary for the side panels 32 to be designed as shown in
It has been mentioned that the handle 36 of the child transporter 10 can be used to provide a carrying handle for the child transporter 10.
When the child transporter 10 is to be stored or itself transported, the handle 36 is rotated with respect to the seat assembly 14 by releasing the rotatable joint adjacent the seat assembly 14 to allow the handle 36 to be folded towards the hand grip 26. The sprung pins 44 are released to allow the second section 38b of the handle 36 to slide telescopically with respect to the first section 38a until the transverse portion 40 is looped over the handgrip 26. A second spring pin 44a is provided to hold the second section 38b in the correct position with respect to the first section 38a so that the handle 36 cannot move with respect to the handgrip 26. The shape of the handgrip 26 ensures that the handle 36 remains in a fixed relationship with the seat assembly 14. The handle 36 can then be used to transport the child transporter 10 as required.
Another embodiment of the child transporter is shown in
A further variation to the embodiments described above lies in the type of wheel which can be used in the child transporter 10. In the preceding paragraphs, it is envisaged that the wheel 12 will be of the type commonly used in apparatus used for transporting children such as children's scooters or bicycles. Such wheels may be rubber or inflated but will normally have a rounded profile as illustrated in
It is envisaged that the child transporter 10 could be manufactured from a variety of different materials. For example, the frame 16 and handle 36 may be manufactured from aluminium to provide strength and rigidity whilst being lightweight. Other materials may be used, including steel. The seat portion and side panels may be manufactured from a plastics material, although wood may also be used. The wheel may be aluminium or another metal such as steel, or may be wooden or plastic.
Turning now to the embodiment shown in
The child transporter 200 includes two features not included in the first previous embodiment. First, the handle 230 includes, at its distal end, an upwardly extending grip portion 234 which also extends in a forwards direction, away from the adult in control of the child transporter 200. The grip portion 234 is here shown as a simple rod-shaped element but can be made any convenient shape for gripping by a user in the manner described below. The second feature not included in the first previous embodiment is the stabiliser 240. The stabiliser 240 consists of a generally U-shaped bracket 242 which is either connected to the frame 222 in the vicinity of the footrests 228 or may be integrally formed with the frame 222. The bracket 242 extends rearwardly so as to surround a lower, rearward portion of the wheel 220. The bracket 242 carries two stabilising wheels 244 which lie on a common axis lying behind the wheel 220. The stabilising wheels 244 are positioned so that they are spaced apart by a distance which is greater than the width of the wheel 220. This means that, when the stabilising wheels 244 are in contact with the ground, the points of contact of the wheel 220 and the stabilising wheels 244 form a triangle.
The stabiliser 240 is fixedly connected to the handle 230 via the frame 222. This means that, when the wheel 220 is in contact with the ground and the handle 230 is lifted away from the ground, the stabilising wheels 244 will also be lifted away from the ground. When the handle 230 is lowered towards the ground, the stabilising wheels 244 will be lowered towards the ground.
The child transporter 200 can be used in the following manner. When used at low speeds, and particularly on relatively smooth surfaces, the adult has the option to grasp the grip portion 234 rather than the transverse portion 232. Because the grip portion 234 is above the transverse portion 232, the natural position of the adult's hand will bring the distal end of the handle 230 into a relatively low position compared to the position in which it would be if the adult were to grasp the transverse portion 232. This will lower the stabiliser 240 and bring the stabilising wheels 244 into contact with the ground as shown in
It is envisaged that the stabiliser 240 can be made detachable from the frame 222 simply by using sprung pins of the type described above or by any other readily available detachable connectors. It is also envisaged that the shape of the grip portion 234 could be varied from that shown and that the stabilising wheels 244 could be replaced by a single roller or other rolling support elements. The stabiliser 240 could, if required, be arranged to extend forwardly so that the stabilising wheels 244 were located underneath the footrests 228. In this instance, the grip portion 234 would be arranged to extend downwardly from the transverse portion 232 so that, in use, transferring one's grip from the transverse portion 232 to the grip portion 234 would lower the stabilising wheels 244 onto the ground.
The skilled reader will appreciate that the invention is not strictly limited to the details given in the above detailed description. Variations and alterations will be apparent to a skilled reader.
