(6) FIG. 5 is a perspective cutaway view of the undercarriage and the folding mechanism of FIG. 4, along a transverse central plane of the item of luggage of FIGS. 1 to 4; and

(7) FIG. 6 is an enlarged view of the undercarriage of the item of luggage of FIGS. 1 to 5.

(8) Referring to FIG. 1, there is shown an item of luggage in accordance with the present invention, indicated generally as 1. The item of luggage 1 comprises a semi-rigid case 2 formed of expanded polyurethane. The case 2 is shaped to accommodate a handle 3 which passes through it and is connected by an undercarriage, indicated generally as 4, to a pair of wheels 5 and 6. The handle 3 is telescopic and locks in the extended position shown in FIG. 2. The handle 3 has a button 7, which when depressed enables the handle 3 to be lowered. An additional carry handle 8 is also provided on the case 2.

(9) With the telescopic handle 3 raised, as shown in FIG. 2, the item of luggage 1 may be wheeled in the manner of a conventional wheeled suitcase or flight bag.

(10) The item of luggage 1 of FIG. 1 may have any desired overall dimensions, but these may be selected so that it may comply with applicable carry-on luggage requirements of aircraft operators.

(11) With continued reference to FIG. 1, the undercarriage 4 comprises a support member 9 formed from a rigid injection moulded plastic. To this is mounted a bracket 9, which bracket 9 is also secured directly to the case 2 by shield plate 10. Pivotally mounted to the bracket 9 is the proximal end of footplate 11. Footplate 11 has mounted at its distal end a wheel 12.

(12) The case 2 has moulded into its back face a recess 13, in which recess 13 the footplate 11 and wheel 12 are accommodated when the footplate 11 is in a raised, folded configuration shown in FIG. 1.

(13) With reference now to FIG. 2, there is illustrated the same item of luggage 1 as shown in FIG. 1, but in FIG. 2 the telescopic handle 3 has been raised and the footplate 11 lowered to form a scooter 1, with the pair of wheels 5 and 6 now forming the front pair of wheels of the scooter 1, with the wheel 12 at the distal end of the footplate 11 forming a rear wheel 12 of the scooter 1 and with the telescopic handle 3 becoming the handlebar 3 of the scooter 1.

(14) As will be described in greater detail below with reference to FIGS. 5 and 6, there is provided a locking mechanism between the bracket 9 and footplate 11 which locks the footplate 11 in the position shown in FIG. 2. Additionally, the undercarriage 4, as is also described later, permits the scooter 1 to be steered by leaning the handlebar 3 to the left or right, causing the pair of wheels 5 and 6 to turn to the left or right respectively.

(15) Referring now to FIGS. 3 and 4, these are views which correspond to FIGS. 1 and 2 respectively, but which show to an enlarged scale the components of the undercarriage 4 and its connection to the footplate 11 when in the folded configuration (FIG. 3) and the extended configuration (FIG. 4).

(16) FIG. 5 is a cutaway section through the component shown in FIG. 4 taken along a transverse plane of the footplate 11 and undercarriage 4. This shows the various components seen in FIG. 5, but also discloses the locking mechanism, indicated generally as 14, for locking the footplate 11 in the positions shown in both FIGS. 3 and 4.

(17) Referring now primarily to FIG. 5, but also with reference to FIGS. 3 and 4, there is shown a support member 15 of the undercarriage 4 mounted below the fabric of case 2, with a portion 16 of the support member 15 extending through a hole in the bottom of the case 2. The bottom of the telescopic handle 3 is received and locked in place in the support member 15 by pin 17. A plate 18, injection moulded from a rigid plastic to substantially match the contours of a portion of the case 2 is positioned, as shown in FIG. 5, to sandwich the portion of the case 2 to the support member 15 of the undercarriage 4 and thus the plate 18 mounts the support member 15 on to the case 2.

(18) A bracket 9 is mounted to the support member 15 by fasteners 19. The bracket 9 is also mounted directly to the case 2 by shield plate 10, which both acts to stabilise the position of the bracket 9 and prevent the bracket 9 snagging on any raised obstacle.

(19) The footplate 11 has at its proximal end a section of square tube 20, secured by fasteners 24 and 25 to an extruded aluminum section 23, forming the main body of the footplate 11. The section of square tube 20 has, on opposite sides, two slots 21 (only one of which can be seen in FIG. 5) through which slots 21 pivot pin 22 extends, which pivot pin is retained in a fixed location in the bracket 9. This arrangement permits the footplate 11 to pivot about the pin 22 from the folded configuration of FIG. 1 to the extended configuration of FIG. 2. It also permits the footplate 11, including the section of square tube 20, to move longitudinally by virtue of the pin 22 sliding along the slots 21.

(20) A spring 26 acts between fastener 25 and the pivot pin 22 (which may also be a fasteners) and biases fastener 25 towards the pivot pin 22 and thus biases the foot plate 11 towards the bracket 9, so that it adopts the position shown in FIG. 5. The locking mechanism 14 additionally comprises a locking pin 27 which extends out through opposite sides of the section of square tube 20 and is urged by the action of spring 26 into contact with curved edges 9a and 9b of the bracket 9. It thus engages with opposed pairs of notches 28, 29 and 30, 31 in the curved edges 9a and 9b of the bracket 9 and thus acts to lock the footplate 11 in either the folded configuration shown in FIG. 3 or the extended configuration shown in FIG. 4. Two end caps 32 and 33 are also provided to protect the locking mechanism 14 from the ingress of dirt.

(21) Although not shown in the figures, the locking pin 27 may be further extended so that it extends past the curved edges 9a and 9b of the bracket 9. A secondary locking member may then be provided, in the form of a hook attached to the bracket, which may be hooked over the locking pin 27 when the locking pin is located in notches 30 and 31, in order to prevent the footplate 11 being pulled away from the bracket 9. Thus the secondary locking member ensures that the footplate 11 remains locked in the extended position as shown in FIG. 5, unless the secondary locking member is first released.

(22) The locking mechanism described above with reference to FIG. 5 enables the footplate 11 to be released from the folded configuration, shown in FIG. 1, by simply holding the wheel 12 or footplate 11, raising it vertically against the force of the spring 26 so that the locking pin 27 is disengaged from the notches 28 and 29. It may then be lowered to the extended position shown in FIG. 2. Here the spring 26 automatically urges the locking pin 27 into the notches 30 and 31, locking the footplate 11 in the extended position shown in FIG. 2, where a secondary locking member (not shown) may be hooked over the pin 27 to prevent accidental release of the footplate 11 from the locked position shown in FIG. 2.

(23) To fold the footplate 11 from the configuration shown in FIG. 2 back to the folded configuration of FIG. 1, any secondary locking member is first released, the footplate 11 pulled away from the case 2 to enable it to be folded vertically to the position shown in FIG. 1. Here the spring 26 biases the locking pin 27 into the notches 28 and 29, again locking the footplate 11 in the folded position of FIG. 1.

(24) Those features of the undercarriage which permit the scooter 1 to be steered by leaning the handlebar 3 (telescopic handle) to the left or right will now be described with reference to FIGS. 4 and 6.

(25) The undercarriage, indicated generally as 4, comprises a support member 15 fixed to the bottom of the case 2. At either transverse end of the support member 15 is a downwardly protruding spindle 34, 35 each of which is inclined at an angle, so that it extends both downwardly and towards the rear of the scooter. On each spindle there is rotatably mounted a respectively first or second steering components 36 and 37, which each support a respective axle 41, 42 of respective wheels 5, 6.

(26) A track rod 38 is pivotally connected at either end to respective ones of the first and second steering components 36, 37 and acts to keep the first and second steering components 36, 37 aligned. This thus keeps the wheels 5, 6 aligned.

(27) As can perhaps be most clearly seen from FIG. 5, a spring 39 is attached to the support member 15. Respective ends of the spring 39 (only one of which can be seen in FIG. 5) pass through two apertures 40 (only one of which can be seen in FIG. 5) in the track rod 38 and the spring 39 acts to center the track rod 38 and thus keep the wheels 5, 6 in a straight ahead position, as shown in FIG. 6.

(28) With reference now to FIG. 6, when pressure is exerted on the handlebar 3 of the scooter 1, pushing it to the left of FIG. 6, this urges the wheel 5 to move upwards relative to the support member 15 and permits the wheel 6 to move downwards relative to the support member 15. Because of the inclination of the spindle 35, movement of the wheel 5 upwards relative to the support member 15, also causes the wheel 5 to move backwards (out of the page as shown in FIG. 6) as the associated axle 41 rotates about the spindle 35, turning the wheel 5 to the left. The track rod 38 causes the wheel 6 to be rotated in the same direction by the same amount. Thus when the scooter 1 is travelling in a forward direction, (into the page as shown in FIG. 6), pushing the handlebar 3 to the left causes the wheels to angle to the left and steer the scooter 1 to the left. Likewise, pushing the handlebar 3 to the right causes the scooter 1 to the turn to the right.

(29) Although one embodiment of the invention has been described above with reference to the accompanying figures, it will be appreciated that many modifications may be made within the scope of the appended claims. For example, the case 2 could be detachable from the remaining components of the scooter. This would require the telescopic handle 3 to be located outside of the case 2 and it may require appropriate fitments to be provided on the support member 15 and/or handle 3 to which the case may be releasably attached, the case having, if appropriate, reinforcing elements either moulded or secured thereto, arranged to releasably engage the fitments on the support member 15 and/or telescopic handle 3.

(30) In addition to the above, the case 2 is illustrated is formed of a semi-rigid material. However, it could equally be a soft case, similar to a soft holdall with the telescopic handle 3 either passing through it or with the holdall portion again releasably attached to the remaining components. With this arrangement it may be necessary for the undercarriage to comprise guards to ensure the soft bag does not contact the wheel 5, 6.

(31) In yet another alternative, the case could be in the form of a rucksack with straps mounted thereto. In such an arrangement, the handle may be arranged to draw the straps into the rucksack when the telescopic handle is raised. If the rucksack is the form of a rigid or semi rigid case, the accommodation of footplate in a recess 13 may avoid the footplate 11 coming into contact with the back of the person wearing the rucksack. Where the rucksack is a soft bag, the rucksack may additionally comprise a semi-rigid portion to define a recess in which the footplate 11 may be accommodated, to again prevent it coming into contact with the back of a wearer of the rucksack. However, the invention is not to be construed in any way as limited to the additional embodiments mentioned herein.
