BRIEF DESCRIPTION OF THE DRAWINGS The present invention will become more fully understood from the following detailed 25 description of preferred but non limiting embodiments thereof, described in connection with the accompanying drawings wherein: Fig. 1 illustrates an isometric view of an article handling apparatus in accordance with the present invention; 30 Fig. 2 illustrates another isometric view of the article handling apparatus, with the article P:\WPDOCS\AMD\Spifications\I249381 .doc-2 Septanbe 2004 provided in an alternative disposition to that of Fig. 1; Fig. 3 shows an elevational view of the apparatus in the position shown Fig. 1; 5 Fig. 4 shows an elevational view of the apparatus in the position shown in Fig. 2; Fig. 5 shows an isometric view of the article handling apparatus, but without the article in position; 10 Fig. 6 shows an isometric view of the article handling apparatus, again without the article, but in a compact position for storage; Fig. 7 shows a plan view of the article handling apparatus shown in Fig. 5; 15 Fig. 8 shows a plan view of the article handling apparatus shown in Fig. 6; and, Fig. 9 shows an isometric view of the article handling apparatus, incorporating a sliding mechanism. 20 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Throughout the drawings, like numerals will be used to identify similar features, except where expressly otherwise indicated. As shown in the drawings, the article handling apparatus, generally designated by the 25 numeral 1, includes a base frame portion, generally designated by the numeral 2, for movement of the apparatus 1 over a substrate surface, and, a handling frame, generally designated by the numeral 3, for gripping and moving an article, such as a tyre 4, shown in Figs. 1 to 4. 30 As seen in the drawings, the base frame 2, includes a pair of moveable arm members 5 extending from a central body portion 6. Most preferably, but not essentially, each of the P:\WPDOCS\AMD\Speifications\249381 I.doc-2 Septembe 2004 -6 arms 5 is articulated about articulation point 7. The illustrated embodiment shows two arm portions 8 and 9 forming each arm 5, the arm portions 8 and 9 being articulated about an articulation point 7. Any number of articulated arm portions may be provided. 5 The base frame 2 includes wheels or other movement means for movement of the base frame and therefore the article handling apparatus over a substrate surface. The illustrated embodiment shows three wheel sets on the base frame 2, indicated by reference numerals 10, 11 and 12. Obviously, additionally wheels could be provided depending upon the particular embodiment. The provision of the wheels on the extremities of the arms and on 10 the central body portion, as illustrated in the embodiment herein described, provides good balance to the apparatus, as will be clearly understood to persons skilled in the art. Articulation of the arm members, may be effected by any known form of actuation means, such as hydraulic cylinders, electric motors, or any combination thereof. The illustrated embodiment shows hydraulic cylinders 13 provided between the members forming arm 9. 15 Obviously the location of actuation means is variable as will clearly understood by a person skilled in the art. The handling frame 3 of the article handling apparatus 1 is also formed of a pair of arm members 14 extending from a central portion 15. The central body portion 15 of the 20 handling frame 3 may either be separate from or formed integrally with the central body portion 6 of the base frame 2. That is, whereas the handling frame 3 is shown in the illustrated embodiment as being upwardly disposed from the base frame 2, and separated by a vertical framework 16, the handling framework could alternatively extend from the central body portion 6 of the base frame 2 and this could be embodied in a more arcuate or 25 curved fashion, rather than the more rigid or angular manner shown in the illustrated embodiment. Likewise, the handling frame 3 may be attached to the central portion 15 via a sliding mechanism 29, such as shown in Fig. 9, to enable further movement, particularly in difficult to reach positions. 30 The ends of each arm 14 of the handling frame 3 are shown to include a gripping means 17, for gripping the tyre or other article to be handled. The gripping means illustrated in P:\WPDOCS\AMD\Spcificatios\1249381.doc-2 Septmbe 2004 the drawings is embodied as a pair of pate plate members, whereby the tyre or other article is gripped by being pressed between the plates 17. As will be understood by persons in the art, the plates 17 are movable about a universal type joint, to allow orientation of the plates 17 depending upon the shape of the article, in any direction. Some of the typical 5 movements capable are illustrated by comparing Figs. 1 and 2 of the drawings. It will be understood that the tyre can be extended about an axis extending between the plates 17 by a full rotation of 3600 whilst likewise the plates 17 may be offset from their pivot points to grip an article of any desired shape or construction. 10 The gripping means 17 may be moved by any conventional means, for instance by an electric motor, by a pneumatic or hydraulic cylinders, or any other form of actuation means known to persons skilled in the art. Likewise, the arms 14, which are also shown in the drawings to be formed of two members 18 and 19 connected about articulation points 20 may also be moved by any known form of actuation means such as hydraulic cylinders, 15 electric motors, etc. The actuation means for effecting articulated movement of the arm members 14 illustrated in the drawings, are in the form of hydraulic cylinders 21. The handling frame 3 is also shown in the drawings to include a substantially vertically extendable central body portion 16 which basically interconnects it to the base frame 2. It 20 will be appreciated by a person skilled in the art that the operation of the central body portion 16 is somewhat analogous to the movements effected by a fork-lift apparatus in that it is able to be moved in a substantially vertical manner, by virtue of an appropriate actuation apparatus, such as electric motors or hydraulic cylinders. The embodiment illustrated shows a pair of hydraulic cylinders 22 to effect such movement. The central 25 body portion 16 shown in the illustrated embodiment also shows the capability of a pivotal connection 23 at the upper end of the central body portion, and a pivotal movement capability between the base frame 2 and the central body portion of a handling frame 3, by virtue of a pivotal connection operable by hydraulic cylinders 24. 30 It will therefore be appreciated that a variety of movements are capable of being performed by the article handling apparatus shown in the drawings. It will further be understood by a PAWPDOCS\MD\Spcificatios\1249381 Ldoc-2 Septmbe 2004 -8 person skilled in the art that the movement capabilities are widely variable. In order to control the operation of the apparatus handling apparatus, this may be effected by means of a remote control device, or by one or more control means built integrally to 5 the device. The device shown in the drawings shows control means, to control movement of the base frame over the substrate surface, together with movement of the handling frame to effect gripping and movement of the article, by virtue of a controller 25, provided adjacent the central body portion 6, and also, by additional controllers 26 and 27 shown adjacent the wheels 11 and 12 respectively at the ends of the arms 5 of the base frame 2. 10 Whilst the controller 25 is shown in the drawings being somewhat displaced from the central body portion by arm 28, such displacement need not be necessary, and, in situations where the length of the article handling apparatus is critical, may be reduced or eliminated. As perhaps illustrated in Figs. 6 and 8, the article handling apparatus of the present 15 invention is able to be very compactly stored by appropriate contraction of the arms towards the central point of the article. Likewise, it will be appreciated that, due to the unique design of the article, the article handling apparatus of the present invention is capable of being manipulated through tight spaces, and the base frame is capable of being provided under vehicles having relatively little height from the substrate surface, to 20 perform a wide variety of manipulating tasks. Whilst the present invention has been hereinbefore described as being particularly appropriate for handling tyres of large earthmoving or mining equipment, primarily because the large size and otherwise awkwardness of handling such components, the 25 article handling apparatus of the present invention will be understood to be able to be easily adapted for handling tyres or wheels of any dimensions, and in fact, for handling articles of a wide variety of shapes and sizes. Whilst the illustrated embodiment shows particular details of such an article handling 30 apparatus, it will be very clearly understood by a person skilled in the art that a wide variety of variations and modifications will become apparent to persons skilled in the art.
P:\WPDOCS\AMD\Specifications\i2493811.doc-2 Septemb 2004 -9 All such variations and modifications should be considered to fall within the scope of the invention as broadly hereinbefore described and as hereinafter claimed.
