Definitions

  • This invention relates to wheeled load-carrying apparatus, for example dollies, trolleys, carts, various articles of luggage and wheelbarrows.
  • Such items are known in very many forms.
  • the motive power to move the load is supplied by the person using the apparatus, and the wheels are mounted so as to be freely rotatable about their axes (hereinafter called wheel axes for simplicity).
  • wheel axes for simplicity.
  • WO 2009/098461 discloses wheeled apparatus for transporting loads where the apparatus has a base structure carrying a pair of spaced apart rotatable ground-engaging members, each mounted for free rotation on the base structure and with wheel axes being coplanar, but at an angle to one another of at least 10°, and the arrangement being such that the angle between the plane of a surface on which the apparatus rests and the plane of the wheel axes may be varied.
  • Such apparatus can be thought of as including a pair of wheels set at a substantial positive camber angle, in contrast to the few degrees of camber angle adopted in many four-wheeled vehicles for the pair of wheels by which the vehicle is steered.
  • WO2009/098461 are generally hemispherical members having an outer ground-engaging surface, which may be provided with a tread, and a central hub which fits the inclined axles on which each hemispherical member rotates.
  • Such hemispherical members are included in the term "wheels" as T/GB2012/000682
  • wheels 2 used herein as well as, for example, more standard types of wheel consisting of a hub, rim and tyre.
  • Such wheels are also known for use in vehicles designed to travel over rugged terrain, as disclosed in US-A- . 4353428, which also discloses such wheels arranged at a substantial positive camber.
  • the wheeled apparatus when the wheel axes are both in a vertical plane, the wheeled apparatus may be easily pulled along the ground in a direction perpendicular to that plane. If the wheel axes are moved out of a vertical plane, because of the substantial positive camber, the two wheels adopt, a splayed or "toed-in" configuration relative to the ground on which they rest, which exerts a braking effect on the apparatus.
  • the apparatus is braked to such an extent that it no longer rolls easily along on the wheels, because each wheel tries to roll on the ground in different directions, though the apparatus can be rotated as a whole about a vertical axis, with each wheel then rolling along a horizontal circular arc centred on that vertical axis.
  • apparatus for transporting loads including a pair of freely rotatable ground-engaging wheels to enable the apparatus to be pulled or pushed along with the wheels in contact with the ground, a load-carrying frame or container supported on the wheels, wherein the wheels have a high positive camber angle and are each mounted for free rotation on a stub axle, a connector piece extends laterally from each stub axle and each connector piece is mounted at its end remote from the stub axle, to enable the connector piece to swivel, relative to the frame or container, about an axis which is horizontal when the apparatus is being used, over an angular range of 5 to 25°, and means enabling the frame or container to be rotated about a horizontal axis relative to the ground on which the apparatus rests.
  • This horizontal axis may be thought of as running in the direction of a "load axle", i.e. the axle on which the load supported by the wheels may rest.
  • the present invention provides a wheeled support structure for use in apparatus as defined above consisting of a pair of wheels mounted on a pair of axles, the axles being inclined to one another by at least 10°, and preferably by 50° to 100°, the axles being mounted at each end of an elongate member constituting a load axle of the apparatus via a connector member at each end thereof, the connector members extending at an angle to the direction of the elongate member and to the axis of the axles, and each elongate member, the axles and the connector members being coplanar.
  • Each connector member is fixed at one end to the elongate member and at the other end to the inclined axle on which the wheel is mounted.
  • the elongate member may be of any appropriate length, and may consist of two elongate members connected together by means enabling the overall length to be varied.
  • the wheel support structure is an elongate bar having a lateral extension at each end, the lateral extensions being coplanar, with the angled axles for the wheels mounted at the ends of the extension members and those axles being coplanar.
  • the bar can be thought of as being a load axle cranked at each end to form a pair of wheel axles.
  • a load-supporting structure such as a box or frame
  • the load axle tries to adopt a position with the extensions going up and the axles of the wheels extending downward from the tops of the extensions and in a vertical plane.
  • the load axle is lower than the wheel axles.
  • the wheeled support structure self- aligns with the elongate member rotating slightly if the wheels are on a sloping surface so that the elongate member and the wheel axles remain in a plane substantially perpendicular to the surface of the slope. The juddering problem noted above is avoided. This occurs because the wheeled support structure can rotate by a limited amount relative to the box or frame.
  • a simple way of achieving this is to provide that the connector pieces are located for movement within a generally sector-shaped area having radial walls defining the angular range over which the connector pieces may swivel relative to the box or frame.
  • the connector pieces first move towards, and then come to rest against, one or other side wall of the sector-shaped area and subsequent movement of the box or frame then moves the axles of the wheels out of the vertical plane, which increasingly points the wheels in different directions and so exerts an increasing braking force on the apparatus, i.e. it can no longer be rolled easily along (though it can still be swivelled about a vertical axis if desired).
  • the present invention thus generally provides load-carrying apparatus comprising a box or frame structure adapted to receive or support a load, means enabling the box or frame structure to be rotated about a horizontal axis relative to the ground on which it rests, and two ground-engaging wheels mounted for free rotation on axles connected to the box or frame structure, wherein the axles can themselves swivel to a limited extent relative to the box or frame structure.
  • the axles on which the two wheels rotate are coplanar in a vertical plane when the apparatus rests on a horizontal surface and are preferably inclined at 75° to 105° to one another, so as to provide a substantial camber angle between the two wheels.
  • Each axle is mounted on the box or frame structure in a fashion allowing it to pivot re)at ' ive thereto about an axis substantially parallel to the ground on which the wheels rest.
  • two wheel and mounting units may be used, each consisting of a wheel mounted on a stub shaft for rotation about a first axis, the stub shaft being mounted at or near one end of a radius arm, and the radius arm being rotatable about a second axis at or near its other end, the two axes being at an angle of at least 30°, preferably 35° to 55°.
  • the length of the crank or radius arm needs to be sufficient. This can be achieved if the axis around which the crank or radius arm rotates lies between the edge of the wheel where it contacts the ground and the end of the hub from which the stub axle emerges.
  • WO 2009/098461 also describes (and illustrates in Figure 5) a three-wheeled item of luggage such as a shopping bag, which rests on all three wheels when vertical and on just two of the three when inclined, so that it can be pushed or pulled along with rotation only of the two ground-engaging wheels.
  • each of the wheels is mounted on the load-receiving part of the item via an intermediate sw/vellable member having on one side a stub axle on which the wheel is mounted and the intermediate member being mounted swivelably about an axis at an angle to the direction of the stub axle.
  • One way of achieving this is to provide on the side of the swivellable member away from the stub axle a set of mounting bars, each of which may slide in a slot in a base member fixed relative to the load-receiving portion. This enables the member to move relative to the base when the angle of the base to the horizontal is varied, i.e. when the item is tipped so as to rest on two wheels only of the three.
  • an item of this type there are three mounting bars and three corresponding slots for each of the wheels.
  • the bars and slots may be interchanged without affecting the working of the apparatus, e.g. the stub .
  • - axle may be mounted on a cup-shaped base having three slots in it into which three bars fitted to the load-receiving portion of the apparatus are inserted.

  • Figure 4 is a perspective view of a suitcase with a detachable wheeled support member
  • Figure 5 is a section through part of the suitcase shown in Figure 4.
  • Figures 6 and 7 show diagrammatically how the invention is applied to a three-wheeled bag.
  • Figure 1 shows diagrammatically an arrangement of a pair of generally hemispherical wheels 1 , 2, each having a central hub 3.
  • the wheels are mounted on opposite ends of an elongate member which consists of a central straight bar 5 which act as a load axle.
  • a laterally projecting short section 6 At each end of bar 5 is a laterally projecting short section 6.
  • Each section 6 may be fixed to the end of the central bar 5, or it may be bent out from, and integral with, bar 5.
  • Figure 2 shows the arrangement shown in Figure 1 set in a supporting base member 10 having a groove in it in which bar 5 is rotatably mounted. At each end of bar 5, section 6 lies within a generally triangular or sector-shaped recess 1 1 formed in base member 10; The sides of each recess limit the degree to which bar 5 can rotate about its elongate axis relative to base member 10.
  • Base member 10 may be attached to a box structure to form a wheeled article of luggage, as shown in Figure 3.
  • the article of luggage consists of a box structure 15 having set into one side of it an extendable handle 16 which is set on a pair of struts 17 to enable it to be extended from, or stowed adjacent to, the box structure 15 in known fashion.
  • the handle 16, struts 7 and the locking mechanism for locking struts 17 in position are of standard construction.
  • the angles and dimensions are such that when the handle 16 is extended and the user wishes to pull or push the case along, usually with the ⁇ telescopic members 17 lying in a plane inclined at 30 to 45° to the horizontal, the sections 6 lie within the boundaries of recesses and central bar 5, sections 6 and the stub axles 7,. all lie in an essentially vertical plane. They continue to lie in that vertical plane even if the general angle of inclination of the body 15 to the horizontal is varied within the e.g. 30 to 45° range.

It shows a wheel 40 running on a stub axle 41 which is fixed to a plate 42 which itself has three pins 44 protruding from the back of it. These pins 44 pass through slots 45 in a moulding 46 (which forms the base of the bag) and are held captive by suitable heads 47 so that the plate 42 is fixed to the moulding 46, but can move according to the shape of the slots 45.
  • a moulding 46 which forms the base of the bag
  • the slots 45 are not simply cut through a flat plane; the edges of the slots 45 are ramped in such a way that the plate 42 when it moves, as pins 44 slide in, the slots 45, tilts relative to its starting plane.
  • the positions of the pins 44 and slots 45 and the shaping of the ramps enable the plates, and hence the stub axles 41 and wheels 40, to swivel relative to moulding 46. This motion is repeated for each two-wheel combination due to the symmetry of the system.
  • the start angle for this effect will be the same as for the fixed axle three-wheeler shown in 00682
