Abstract

A shopping trolley includes a frame 2, and a castor wheel arrangement 16 comprising a roller 28 turnable about a horizontal first axis, a bracket 26 mounting the roller 28 and turnable about an upwardly extending second axis perpendicular to the first axis and provided by a metal bearing pin 30 forming part of the bracket 26, a metal housing 18 mounting the bearing pin 30 and turnable about a horizontal third axis substantially perpendicular to the second axis and fixed relative to the frame, the housing 18 being of a non-circular internal cross-section. The third axis is provided by a metal pivot pin 20 which extends transversely of the bearing pin 30 through a lateral recess in the bearing pin 30 and is carried by the housing 18 and serves to abut against the lower longitudinal end of the recess, there being an anti-friction bearing member fixed to the bearing pin 30 and of an external cross-section substantially corresponding to the internal cross-section of the housing 18 and serving to prevent turning of the bearing pin 30 relative to the pivot pin 20 to the extent that the pin 30 contacts the pin 20.

Description

APPARATUS
This invention relates to a vehicle including a castor wheel arrangement.
According to one aspect of the present invention, there is provided a vehicle including:- a frame, and a castor wheel arrangement comprising a roll turnable about a first axis, bracket means mounting said roll for turning about said axis and turnable about an upwardly extending second axis substantially perpendicular to said first axis and provided by a bearing pin forming part of said bracket means and also substantially perpendicular to said first axis, bearing means mounting said bearing pin and turnable about a third axis substantially perpendicular to said second axis and fixed relative to said frame.
Owing to this aspect of the invention, it is possible to reduce relatively the production cost of the castor wheel arrangement.
According to another aspect of the present invention, there is provided a vehicle including:- a frame, and a castor wheel arrangement comprising a roll turnable about a first axis, bracket means mounting said roll for turning about said axis and turnable about a second axis substantially perpendicular to said first axis and provided by a metal bearing pin forming part of said bracket means, and metal housing means mounting said bearing pin and mounted upon said frame, said housing means being of a non-circular internal cross-section, a lateral recess in said bearing pin, a metal abutment extending transversely of said bearing pin through said recess and carried by said housing means and serving to abut against at least one longitudinal end of said recess, and an anti-friction bearing member fixed to said bearing pin and of an external cross-section substantially corresponding to the internal cross-section of said housing and serving to prevent turning of said pin relative to said abutment to the extent that said pin contacts said abutment.
Owing to this aspect of the invention, it is possible to avoid metal-tometal sliding contact between the bearing pin and the abutment and so avoid consequential wear.
In order that the invention may be clearly and completely disclosed, reference will now be made, by way of example, to the accompanying drawings, in which:- Figure 1 is a fragmentary, top perspective view of a shopping trolley, but with parts omitted for the sake of clarity, and Figure 2 is an exploded, underneath perspective view of a castor wheel arrangement of the trolley.
Referring to the drawings, the trolley includes a frame 2 which includes struts (omitted for the sake of clarity) to which is fixed a basket 4 of the trolley. The frame 2 carries front and rear pairs 6 and 8 of castor wheels. The frame includes two lateral members 10, a horizontal cross-member 12 and a shallow-V-shaped cross-member 14. At the vertex of the member 14 is mounted a castor wheel arrangement 16 which provides a fifth wheel to deter lateral movement of the trolley, particularly under gravity on a transverse slope of the ground or floor. The arrangement 16 includes an upwardly extending, tubular, steel housing 18 of square cross-section, closed at its upper end l8A and open at its lower end l8B.
The housing 18 is mounted on the cross-member 14 by way of a horizontal, steel, pivot pin 20 whereof the ends are borne in bearing holes in respective lugs 22 and 24 fixed to the cross-member 14. The lug 24 is of an angular form to extend in front of the housing 18 at a location above the level of the pin 20 to provide a stop to limit forward turning of the housing 18 about the pin 20. The member 14 itself includes a portion which provides a stop above the level of the pin 20 to limit rearward turning of the housing 18. The arrangement 16 also includes a bracket 26 and a roll 28 embraced thereby.
The bracket 26 is mounted in a threaded bore 32 in the lower end of an upwardly extending bearing pin 30 which is co- axially mounted in the housing 18 so as to be longitudinally displaceable relative to the housing 18, but not turnable relative thereto. The bracket 26 is rotatable about the axis of the pin 30, which is perpendicular to the axis of rotation of the roll 28. Progressing upwardly from the bore 32, the pin 30 is formed externally with a lateral, rectangular recess 34, a flat 36, and a lower annular rectangular groove 38 and an upper annular rectangular groove 40 both co-axial with the pin 30 and intersected by the flat 36. Mounted in the respective grooves 38 and 40 so as substantially to fit longitudinally slidingly in the housing 18 and to encircle closely the pin 30 are split bearing rings 42 and 44 of polyamide/graphite material to promote slidability on the inside surface of the housing 18. The rings 42 and 44 project sufficiently from the pin 30 to prevent contact between the housing 18 and the pin 30, so as to prevent metal-to-metal contact, particularly sliding contact, which promotes wear.
The chordal depth of the recess 34 is sufficiently great that, provided that the base surface 34A thereof remains substantially parallel to the pin 20, there is a small spacing between the pin 20 and the surface 34A. The transverse bars 42A and 44A bounding the substantially closed Ushapes of the interiors of the rings 42 and 44 co-operate with the flat 36 to prevent the pin 30 from turning about its own axis relative to the pin 20 sufficiently that the surface 34A contacts the pin 20, so that metal-to-metal sliding contact therebetween is prevented. A helical compression spring 46 acts between, on the one hand, a shoulder at the lower end of a co-axial bore (not seen) formed in the pin 30 from the upper end 30A of the pin 30 and, on the other hand, the inside surface of the closed upper end l8A of the housing 18, so as continuously to urge the pin 30 downwardly relative to the housing 18. The inside surface of the end 18A is provided with a centering boss (not seen) for the spring 46, the boss extending into the upper end of the spring. The pin and a pin 48 parallel to and at a higher level than the pin 20 are mounted fixedly in respective pairs 50 and 52 of unilateral, transverse holes in the wall of the housing 18.
The condition of maximum extension of the spring 46 is defined by the bar 44A coming to bear lightly against the pin 48, which always remains out of contact with the pin 30, to prevent the upper end surface 34B from contacting the pin 20. The condition of minimum extension of the spring 46 is defined by the pin 20 abutting the lower end surface 34C of the recess 34. The form of the cross-member 14 and the level of the upper end l8A of the housing 18 are advantageously such that the front cross-bar (12) of an identical trolley nested-in from the rear can pass over the housing 18 to give good nestability.
In use, when the trolley is being pushed forward, the housing 18 occupies a forwardly tilted condition in which it bears on the lug 24, with the pin 30 forwardly tilted, and in which the fifth wheel (28), urged into contact with the ground or floor by the spring 46, tends to maintain a straight path of travel of the trolley, even on a transverse slope. To change direction, the user simply pivots the trolley around the fifth wheel, except that, when the user moves the trolley backwards, the roll 28 turns the housing 18 into its vertical condition in which it bears against the cross-member 14 and in which the pin 30 is vertical and thus the roll 28 does not substantially deter movement of the trolley in any desired rearward direction.
