Description: IMPLEMENT FOR COLLECTING ANIMAL FAECES This invention relates to an implement for collecting animal faeces particularly when you are out walking the dog or other animal, or after other animals have excreted in your garden or in a play area. Accordingly, the present invention is an implement for collecting animal faeces comprising a baton in which the lower portion at least is tubular with towards the lower end being enlarged and having an open end whereat a disposable cartridge is internally fitted, the cartridge having collecting means with one or a series of apertures .which are in communication with a container located within the baton, and means to eject the cartridge from the baton for disposal after use, the cartridge having an containment ring positioned externally of the baton and the collection means having a ring member in which is defined the one or the series of apertures, the ring member being movable relative to the containment ring during a faecal matter lifting operation. Preferably, the collecting means comprises a tubular body at one end across which the ring member is provided, the other end having the container, e.g. a bag of plastics material, and catch means to be engaged by gripping means provided at the lower end of an internally movable sub-assembly. The sub-assembly desirably comprises a frusto-conical cone having an open lower end with the gripping means and a closed upper end connected by a rod to a handle at the top of the baton and mounted for movement relative to the baton. Towards the top of the baton, two metrically opposite guideways are beneficially provided having a first elongate part parallel to the longitudinal axis of the baton, a second transverse part at the top of the first part and a third shorter elongate part parallel to the first elongate part and extending upwardly. The inside of the handle has preferably two diametrically inwardly extending guides to track the guideways. A detent or sleeping policeman is beneficially provided in the second transverse part to prevent accidental movement between the first and third parts. The handle is desirably spring-biased away from the baton and the length of the first elongate part of the guideway determines the extent of movement of the ring member between a position at the top of the containment ring and at its bottom, i.e. the extent of its lifting movement. Rotational movement of the handle desirably causes the guides to move across into the second transverse part of the respective guideway past the detent or sleeping policemen and into the third part, the handle moving under spring-biasing to cause the gripping means to separate from the catch means and the cartridge to be ejected, the limit of the handle movement determined by the length of the third part of the guideway. Preferably also, the containment ring has an inwardly-directed lip at its upper end and the tubular body below the ring member has an outwardly-directed flange to engage the lip. The containment ring desirable has a friction-fit shoulder at its upper end to engage with the bottom end of the tubular wall of the baton. This serves to prevent upward movement of the cartridge as the cartridge is about to be ejected by upward movement of the sub-assembly. A cap is desirably provided to be a friction-fit over the bottom end and sides of the containment ring. Preferably further, the ring member has a series of radial fingers extending inwardly from its periphery. Eight fingers are desirably in the series, four fingers being longer than the other four fingers, the longer fingers alternating with the others. The inner ends of all fingers each beneficially have a bulbous end. An embodiment of the present invention will now be described by way of example, with reference to the accompanying drawing, in which:- Fig. 1 shows a cross-sectional view of an implement according to the present invention, showing a baton 10 with a cap in position over a containment ring; Figs. 2A, 2B, 2C and 2D show in cross-sectional views of the lower part of the baton a sequence of actions involved in the use of the baton, the containment ring having the cap thereover, and with the cap removed, the containment ring pushed into faecal matter to be lifted, a ring member pushed into the faecal matter, and the baton lifted out of the faecal matter with the faecal matter held on the other side of the ring member respectively; Fig. 3 shows an enlarged view of a guideway provided at the upper end of the baton 10; and Fig. 4 shows an enlarged view of the ring member. Referring to the drawings, an implement for collecting animal faeces comprises a baton 10 in which the lower portion 10A at least is tubular with towards the lower end 10B being enlarged and having an open end whereat a disposable cartridge 12 is internally fitted. The cartridge 12 has collecting means with one or a series of apertures which are in communication with a container 14 located within the baton 10. Means to eject the cartridge 12 from the baton 10 for disposal after use is provided. The cartridge 12 has a containment ring 16 positioned externally of the baton 10. The collection means having a ring member 18 in which is defined the one or the series of apertures. The ring member 18 is movable relative to the ' containment ring 16 during a faecal matter lifting operation. The collecting means comprises a tubular body 20 at one end across which the ring member 18 is provided, the " other end having the container 14, e.g. a bag of plastics material, and catch means in the form of a continuous or part continuous peripheral rib 22 to be engaged by gripping means provided at the lower end of an internally movable sub-assembly 24. The sub-assembly 24 comprises a frusto-conical cone 26 having an open lower end with the gripping means and a closed upper end connected by a rod 28 to a handle 30 at the top of the baton 10 and mounted for movement relative to the baton 10. Towards the top of the baton 10, two diametrically opposite guideways 32 are provided having a first elongate part 32A parallel to the longitudinal axis of the baton 10, a second transverse part 32B at the top of the first part 32A and a third shorter elongate part 32C parallel to the first elongate part 32A and extending upwardly. The inside of the handle 30 has two diametrically inwardly extending guides 34 to track the guideways 32. A detent or sleeping policeman 36 is provided in the second transverse part 32B to prevent accidental movement between the first and third parts 32A, 32C. The handle 30 is spring-biased by a tension spring 38 away from the baton 10 and the length of the first elongate part 32A of the guideways 32 determines the extent of movement of the ring member 18 between a position at the top of the containment ring 16 and at its bottom, i.e. the extent of its lifting movement. Rotational movement of the handle 30 causes the guides 34 to move across into the second transverse part 32B of the respective guideway 32 past the detent or sleeping policemen 36 and into the third part 32C, the handle 30 moving under the spring-biasing to cause the gripping means to separate from the catch means and the cartridge 12 to be ejected, the limit of the handle movement determined by the length of the third part 32C of the guideway 32. The containment ring 16 has an inwardly-directed lip 40 at its upper end and the tubular body 20 below the ring member 18 has an outwardly-directed flange 42 to engage the lip 40. The containment ring 16 has a friction-fit shoulder 44 at its upper end to engage with the bottom end 46 of the tubular wall of the baton 10. This serves to prevent upward movement of the cartridge 12 as the cartridge 12 is about to be ejected by upward movement of the sub-assembly 24. A cap 48 is provided to be a friction-fit over the bottom end and sides of the containment ring. The ring member 18 has a series of radial fingers 50 extending inwardly from its periphery. Eight fingers 50 are in the series, four fingers being longer than the other four fingers, the longer fingers alternating with the others. The inner ends of all fingers each have a bulbous end 52. The gripping means is a continuous or dis-continuous groove 54 provided internally of the cone 26, the rib 22 and groove 54 being matable. In use, with the cap 48 removed, the containment ring 16 is pushed into the faecal matter to be lifted and is advantageous since it prevents the faecal matter trapped therein from spreading outwardly as the ring member 18 is pressed down into and through the faecal matter and ensuring the trapped faecal matter is all held by the ring member 18. The baton 10 is then used again to lift another portion of the faecal matter, the second portion of the faecal matter pushing the first portion upwardly into the container. The baton 10 is used in this way as often as is required to lift all the faecal matter at the one location and at a series of locations, if necessary, during an exercising walk with the pet animal, generally a dog. The handle may be constructed to have a closable cavity for carrying a disinfectant, a self-defensive offensive liquid, for example mace, or accommodation for a torch or an alarm mechanism. Where the cavity holds a liquid, a spray nozzle may be associated with dispersement of the liquid. Variations and modifications can be made without departing from the scope of the invention described above and as claimed hereinafter.
