Definitions

• the present invention relates to a shopping trolley that can be detachably connected to a baby carriage, or perambulator, and being of the kind defined in the preamble of Claim 1.
• the object of the present invention is to provide a shopping trolley construction that enables the trolley to be detachably connected to a baby carriage or perambulator of different models and designs in the manner of a trailer.
• the object also includes the design or construction that will enable the user to stand behind the trolley and still be able to comfortably reach the pulling/pushing handle of the baby carriage so as to push the carriage and therewith pull the trolley.
• the objects also include a trolley construction which renders the trolley stable and less liable to tip.
• the object also includes a construction that will enable the direction of movement of the baby carriage coupled to the shopping trolley to be changed by tipping the carriage onto its rear wheels and swinging the carriage handle so as to release engagement of the front wheels with the floor, in a conventional manner.
• the object also includes the ability of coupling the shopping trolley to different baby carriages in a beneficial and simple fashion. This object is achieved in accordance with the invention with a shopping trolley defined in the following independent Claim.
• the inventive trolley is primarily intended to accommodate so-called shopping baskets, i.e. standard shopping baskets that are designed and dimensioned to enable them to be easily carried on the arm of a shopper.
• the invention comprises providing the trolley chassis with a draw bar or tow bar that includes at its outer end means for coupling the bar to a pushing/pulling handle on the baby carriage.
• the coupling means is located centrally above a polygon whose corner points are defined by the points on which the trolley is supported against the surface of the floor.
• the trolley will include a front wheel that will lie immediately behind the rear end of the carriage chassis.
• the handle of the baby carriage extends generally obliquely rearwards and upwards from the carriage chassis, wherein the front part of the loading surface can be placed in a region immediately behind the carriage and beneath the handle of the carriage, so that the shopping trolley will take up only a small amount of space behind a vertical plane that extends through the gripping part of the handle while enabling the carriage to be easily tipped forwards at the same time.
• the trolley draw bar is designed to allow the coupling means to move vertically in relation to the trolley chassis.
• the coupling means may be connected to the carriage handle by means of a telescopic and vertically orientated connection.
• the trolley will also preferably include a biasing spring that functions to move the coupling means to a vertical upper end position, and thus enable the coupling means to be pressed down towards the trolley chassis against the action of a spring force.
• a wheel is also provided on each rear corner of the trolley, and the trolley chassis will preferably include an edge beam that extends along a path outwardly of said line so that a support foot that is normally spaced a short distance from the floor surface is able to provide a supportive point that counteracts tipping of the trolley around said line.
• a shopping trolley that includes the inventive features is stable and can be swung relative to the baby carriage, or perambulator, in the horizontal plane, and the effective protrusion of which behind the baby carriage handle is acceptably small at the same time as the trolley is stable against tipping of the trolley and the bottom goods carrying surface of the trolley is able to support two conventional baskets side-by-side, wherein a further basket can be placed at a higher level in a basket holder placed on a generally vertical section of the draw bar, wherein the upper basket holder enables a basket to be placed behind the baby carriage handle, as seen in the forward direction of carriage movement.
• the bottom basket supporting surface of the trolley may conveniently have the form of a platform whose front edge is hinged to the chassis so as to enable the platform to be lifted up against the draw bar.
• the upper basket carrier may have the form of a frame that can be lifted to a generally vertical position, this lifting facility enabling the inventive shopping trolleys to be stacked together in their pushing direction.
• Fig. 1 is a schematic side view of the inventive trolley coupled to a baby carriage
• Fig. 2 is a schematic view taken on the line II-II in Fig. 1;
• Fig. 3 illustrates schematically the free end-part of the trolley draw bar with means for coupling the draw bar to the baby carriage handle.
• Figs. 1 and 2 illustrate a shopping trolley whose chassis, or undercarriage, includes three casters 1, 2, 3, wherein the front caster 1 lies in the longitudinal centre plane of the trolley and the casters 2 and 3 lie essentially on an axis that is perpendicular to the longitudinal centre plane.
• a draw bar 4 is connected to the front region of the trolley chassis 5.
• the front part of the trolley/chassis 5 that connects with the caster 1 has a generally triangular flat shape so as to enable the trolley to be swung relative to the baby carriage 7 despite the front caster 1 lying close to the rear edge of the carriage chassis.
• a draw bar 4 is connected to the front part of the chassis 5 and extends upwards to an extent at which its end-part 41 lies above a central region of the chassis 5.
• the upper end- part 41 of the draw bar is connected to the handle 8 of the baby carriage 7 by means of a coupling 9, and more particularly to a handgrip part 81 that extends generally horizontally and transversely of the direction in which the baby carriage 7 is pushed.
• the end-part 41 of the draw bar 4 is positioned so that the caster 1 will tend naturally to lie foremost in the towing direction of the shopping trolley 11 when drawn, or pulled, by the baby carriage 7.
• the chassis 5 extends along a contour that lies well outside respective lines 14.
• the chassis 5 forms a generally V-shaped element whose legs 51 include a bend 52 approximately in the longitudinal centre region, said bend 52 being spaced outwardly of respective lines 14 so that the leg end-parts 53 that carry the casters 2, 3 are generally parallel with one another.
• support parts 55 Provided on the undersides of the legs 51 in the region of the bends 52 are support parts 55 that extend down to a level immediately above the floor surface 30 on which the casters 1, 2, 3 run.
• the trolley 11 is made particularly stable against tipping, both when moving the trolley in a curved path and when the trolley 11 is pulled straight forwards, by virtue of the caster 1 being located at a considerable horizontal distance in front of the handgrip 81.
• the chassis 5 includes a loading platform 57 which is hinged by a front hinge 56 and on which two shopping baskets 12 can be placed side-by-side with the longitudinal axis of respective baskets extending in the longitudinal direction of the trolley.
• the bottom part of the draw bar slopes upwardly and rearwardly to provide space for the baskets 12 on the bottom platform.
• the upper part of the draw bar 4 carries a rectangular frame 44.
• the frame 44 is hinged so that it can be lifted to a vertical position.
• the frame 44 is configured to receive a shopping basket 12 in the illustrated position.
• the bar section 41 is tubular and has an inner bottom plate 49 which forms a support for a pressure spring 48 that acts on the bottom end of a shaft 47.
• the bottom part of the shaft 47 includes a shoulder 62 that grips beneath a plate 50 fixed to the upper end of the bar section 41 so as to prevent the shaft 47 from being lifted free from the tubular part 41.
• the shaft 47 carries the coupling 9, which in the illustrated case is comprised of a horizontal plate 63 with upwardly facing recesses for accommodating the handgrip 81 of the carriage.
• An upper plate 65 is hinged at 64 to one end of the bottom plate 63.
• the plate 64 also includes recesses for accommodating the carriage handgrip 81, wherein the plates 63, 64 can together enclose the carriage handgrip 81 in any one of a number of selected positions at different horizontal distances from the axis of the shaft 47.
• the free end 66 of the upper plate 65 may have the form of a pin and an elastic rubber tensioning belt 67 may be attached to the bottom plate 63.
• the belt 67 may include one or more pin-receiving openings that are spaced from an attachment end, such as to enable the carriage handgrip 81 to be positively locked.
• the shaft 47 is conveniently rotatable in the tubular part 41.
