    DETAILED DESCRIPTION OF THE EMBODIMENTS

    [0044] With reference to drawings FIGS. 1 to 4, a sweeper apparatus 1 according to an embodiment of the present disclosure is illustrated in a range of views. The sweeper apparatus 1 comprises a panel member 2 having a flexible mat-like structure configured to be moved e.g., by towing, across a ground surface G to sweep the ground surface. The panel member 2 has an underside 3 which, in use, faces the ground surface G to be swept, and an upper side 4 which includes a series of collection surfaces 5 for collecting debris swept from the ground surface G. The panel member 2 further includes a plurality of openings 6 that extend between the underside 3 and the upper side 4 for conveying debris (not shown) from the ground surface G to the collection surfaces 5 on the upper side 4 of the panel member 2. To this end, each of the openings 6 in the panel member 2 includes, or is formed, in a guide structure 7 for guiding the transfer or conveyance of the debris from the ground surface G to the collection surfaces 5 of the apparatus 1. The guide structure 7 at each opening 6 includes an inclined surface 8 which extends, in use, upwards and rearwards from a position adjacent or close to the ground surface G to the associated collection surface 5 on the upper side 4 of the panel member 2. In this connection, the inclined surface 8 extends to a rear edge 9 of the respective or associated opening 6. When the apparatus 1 is moved over the ground surface G, the debris passes from the underside 3 of the apparatus 1 along the inclined surfaces 8 of the guide structures 7 and through the openings 6 to the collection surfaces 5. The collection surfaces 5 In this embodiment comprise sections of mesh material with an array of apertures (not shown) that permit small particles, such as crumb rubber, rubber infill, sand or other infill materials, swept up off ground surface G to pass back to the ground surface G through the mesh.

    [0045] The sweeper apparatus 1 further comprises an assembly 100 that is configured to be mounted on the panel member 2 for trapping the debris that is conveyed to the collection surfaces 5 on the upper side 4 of the panel member 2. The assembly 100 for catching or retaining the debris includes a cover 10 and a frame 11. When mounted on the panel member 2, the cover 10 is supported spaced above the collection surfaces 5 by the frame 11 comprising at least one frame member 12. In this way, the frame 11 cooperates with the cover 10 to form or define a collection space 13 between the cover 10 and the collection surfaces 5 on the upper side 4 of panel member 2. This arrangement provides the user with a clearer view of the debris that accumulates in the collection space 13 and can also facilitate better access when emptying the debris from the collection space. In this embodiment, the at least one frame member 12 comprises two substantially parallel ribs or struts or battens 14 which extend laterally across the panel member 2 for supporting the cover 10 spaced above the collection surfaces 5. In this context, the ribs or struts or battens 14 span or extend across substantial the full width of the panel member 2. Further, the ribs or struts or battens 14 are configured to be secured in a releasable manner to the panel member 2 to form or define the collection space 13.

    [0046] The cover 10 comprises an expanse of a flexible textile mesh or fabric material and the frame 11 shapes the cover 10 over the collection surfaces 5. In this context, the cover 10 may be stretched or tensioned over the frame members 12. To this end, the mesh cover 10 may include an elastic material or a stretch material to facilitate the tensioning or shaping of the cover 10 over the frame 11. In this embodiment, the frame members 12 are fibreglass battens 14 having a rectangular cross-section (i.e., similar to sail battens), preferably with dimensions of 15 mm3 mm, although round cross-sectioned fibreglass rods (e.g., up to 8 mm diameter) would also be suitable. The frame members 12 (i.e., ribs or battens 14) are configured to be releasably fixed or mounted on the panel member 2, preferably via one or more straps 15 with releasable fasteners, such as hook and loop fasteners, like Velcro. This is useful for the quick and easy assembly and disassembly of the apparatus before and after use. Alternatively, or in addition, the cover 10 itself includes integral sleeves 15 for receiving the elongate and flexible ribs or struts or battens 14 which then tension or shape the cover 10. This way, the frame members 12 (i.e., ribs or struts or battens 14) are received or integrated in the sleeves or pockets 15 in the flexible cover 10 to form the debris retaining assembly 100.

    [0047] As can be clearly seen in FIGS. 1, 3 and 4, when mounted on the panel member, the cover 10 has or defines forward-facing opening 16 into the collection space 13 formed between the cover 10 and the upper side 4 of the panel member. That is, the opening 16 faces a forward direction or a direction of travel T in which the apparatus 1 is configured to be moved across the ground surface G. Furthermore, the opening 16 extends across a substantial width of the panel member 2, thereby providing a user a clear and unobstructed view of the debris in the collection space 13 as well as easy access to remove collected items. This wide forward-facing opening 16 also operates to collect debris that is flicked-up by a leading edge 17 of the apparatus 1 as it is moved over the ground surface G.

    [0048] The length and width dimensions of the panel member 2 may be selected to suit the particular use, but these dimensions in this embodiment are about 1.5 metres for length and about 2.5 metres for width. A plurality of openings 6 between the underside 3 and the upper side 4 of the panel member 2 for conveying the debris from the ground surface G to the collection surfaces 5 are arranged side-by-side and extend transversely or laterally of the panel member 2 in separate rows 18. Similarly, the plurality of collection surfaces 5 are arranged at locations which are spaced apart from one another along the length of the apparatus, i.e., in the direction of in-use travel or movement of the apparatus 1, with each collection surface 5 being associated with a respective row 18 of openings 6 in the panel member 2.

    [0049] The underside 3 of the mat-like panel member 2 includes a ground-engaging pad or strip 19 extending across its width for agitating loose debris such as leaves, stones, twigs and the like (or foreign objects, e.g., metal objects, such as nuts, bolts, screws, hair pins) on the ground surface G as the apparatus 1 is moved over the ground. The ground-engaging pad or strip 19 is provided along the leading edge 17 of the panel member 2 forward of the openings 6 in the direction of travel T. The ground-engaging pad 19 includes elements, such as bristles or flexible rubber strands, to agitate the loose debris without causing damage to the ground surface G being swept. Also, as can be seen in FIGS. 1, 2 and 4, a trailing edge 20 of the mat-like panel member 2 includes handles 21 for lifting and carrying the apparatus 1 before and after use. The handles 21 are also used for holding and shaking the apparatus 1 to empty the collected debris out of the collection space 13, with the debris then able to fall out of the forward-facing opening 16. The handles 21 may also be used for hanging up the mat-like panel member 2 in storage, i.e., when not in use. A towing member 22 is preferably provided attached to the leading edge 17 of the panel member 2 for hand-drawn or vehicle-towed movement of the sweeper apparatus 1 over the ground surface G. In this regard, the towing member 22 may, for example, be provided in the form of a flexible cord (e.g., for hand-drawn use) or a rigid linkage (e.g., for connection to a vehicle).

    [0050] Referring now to FIGS. 5 to 7 of the drawings, a sweeper apparatus 1 according to another embodiment of the present disclosure is illustrated in different views. As before, the sweeper apparatus 1 comprises a panel member 2 having a flexible mat-like structure configured to be moved e.g., by towing, across a ground surface G to sweep the ground surface. The panel member 2 has an underside 3 which, in use, faces the ground surface G to be swept, and an upper side 4 having a series of collection surfaces 5 for collecting debris swept from the ground surface G. The panel member 2 has multiple openings 6 that extend between the underside 3 and the upper side 4 for conveying debris (not shown) from the ground surface G to the collection surfaces 5 on the upper side 4 of the panel member 2. To this end, each opening 6 in the panel member 2 again includes, or is formed, in a guide structure 7 for guiding the transfer or conveyance of the debris from the ground surface G to the collection surfaces 5 of the apparatus 1. The guide structure 7 at each opening 6 includes an inclined surface 8 that extends, in use, upwards and rearwards from a position at or adjacent to the ground surface G to an associated collection surface 5 on the upper side 4 of the panel member 2. This way, when the sweeper apparatus 1 is moved over the ground surface G, the debris passes from the underside 3 of the apparatus 1 and up the inclined surfaces 8 of the guide structures 7 through the openings 6 to the collection surfaces 5.

    [0051] As like reference signs designate like parts in the sweeper apparatus 1 shown in drawing FIGS. 5 to 7, it will not be necessary to repeat the description of those features already discussed in detail above. This description therefore concentrates on the features of this embodiment which differ from the sweeper apparatus 1 shown in FIGS. 1 to 4. In this regard, it will be apparent from FIGS. 5 and 6 that the frame 11 of the debris retaining assembly 100 of the sweeper apparatus 1 comprises a single fame member 12 in the form of a curved rib or batten 14. That frame member 12 forms or defines a single span that extends transversely or laterally across a width of panel member 2 substantially parallel to the leading edge 17 and substantially perpendicular to the direction of travel T. Again, the curved rib or batten 14 is received or held in a sleeve or pocket 15 of the cover 10 and shapes that cover 10 as shown in the drawings. The rib or batter 14 is preferably fibreglass, once again with a rectangular cross-section of about 15 mm3 mm, although round cross-sectioned fibreglass rods (e.g., up to 8 mm diameter) would also be suitable. The cover 10 of this embodiment includes a movable closure 23, such as a flap or a fabric panel of the same material, arranged across the opening 16 into the collection space 13. In this way, the front or forward-facing opening 16 may optionally be closed or obscured as desired. A zipper Z or other suitable fastening means, such as studs or Velcro straps, can be provided for attaching or securing the movable closure 23 to the cover 10 around a periphery of the opening 16. As before, the assembly 100 is configured to be releasably fixed to the panel member 2 by straps 15 provided at the ends of the frame member 12. The fact that the frame 11 of the assembly 100 has only a single lateral span in this embodiment, here with just a single batten or rib 14, provides easier collapsibility for storage when the sweeper apparatus 1 is rolled-up and/or folded for storage.

    [0052] With reference to drawing FIGS. 8 to 10, a sweeper apparatus 1 and associated assembly 100 according to a further embodiment of the disclosure is shown in a range of views. In this embodiment, the cover 10 of the debris retaining assembly 100 includes a rearward extension 10 that is movable in the direction of arrows E. Considering FIG. 8, the assembly 100 is shown in plan view separated into component parts, including three fabric panels 24, 25, 26 and two pairs of curved ribs or battens 14 forming frame members 12 of the frame 11. Each pair of curved ribs or battens 14 forms or defines a single transverse or lateral span across a width of panel member 2 generally perpendicular to the direction of travel T. To this end, the two partial sleeves or pockets 15 combine when the two fabric panels 24, 25 are stitched together to form a single sleeve or pocket 15 corresponding to the one shown in FIGS. 5 and 6. Indeed, the portion of cover 10 in FIG. 8 comprising the fabric panels 24, 25 generally corresponds to the cover 10 in FIGS. 5 and 6. By adding the extension 10 formed of the fabric panel 26 with a further pair of curved ribs or battens 14, the cover 10, 10 in this embodiment then assumes the form illustrated in FIGS. 9 and 10. As will be appreciated, this assembly 100 affords a substantially larger collection space 13 for holding or retaining debris on the upper side 4 of the mat or panel member 2 in use. The fact that each transverse or lateral span of the frame 11 across the panel member 2 comprises a pair of frame members (i.e., ribs or battens 14) in end-to-end relationship to form the single span provides for enhanced collapsibility of the assembly in storage.

    [0053] With reference to FIG. 11, the adjacent ends 27 of the frame members 12 (i.e., of the ribs or battens 14) may be simply received in respective sleeves or pockets 15 in the cover 10 and separated by one or more lines of stitching. Alternatively, however, with reference in FIGS. 12a and 12b, the frame 11 may include a pivot joint 28 provided in this example in the form of a disc joint, that receives and accommodates the ends 27 of the respective frame members 12 (i.e., of the ribs or battens 14) and provides for relative rotation about a central axis or pivot pin 29 of the joint 28. The pivot joint 28 may also be lockable with the frame members 12 (i.e., ribs or battens 14) may in a particular orientation or positione.g., an extended position or a collapsed position.
