DESCRIPTION OF THE PREFERRED EMBODIMENT

(14) A turf grooming deck according to a preferred embodiment of the present invention will now be described with reference to FIGS. 1 to 9 of the accompanying drawings. The turf grooming deck 10 includes a deck member. 20 mounted to a lawn tractor 12, a first plurality of brush modules 40, and a second plurality of brush modules 50.

(15) The deck member 20 is intended to be mounted to a lawn tractor 12 in a manner substantially similar to attachment of a deck surrounding a blade for mowing grass. More particularly, the deck member 20 is configured to be attached to a lawn tractor 12 and mounted to a framework between a pair of front wheels 13 and a pair of rear wheels 14 (FIG. 1).

(16) The deck member 20 includes a configuration substantially similar to that of a traditional lawnmower deck except as specifically described below. The deck member 20 includes an upper platform 21 (a.k.a. an upper surface) having a generally planar configuration. In an embodiment, the upper platform 21 has a pentagonal configuration, e.g., a geometric shape having five corners and five edges. Further, the deck member 20 includes a plurality of downwardly depending surfaces that will be referenced as including a front wall 22, a rear wall 23, and a pair of sidewalls 24 extending between the front 22 and rear 23 walls, respectively. A bottom surface of the upper platform 21 and the downwardly depending walls, together, define an interior area 27. In an embodiment, the turf grooming deck 10 may include at least one magnetic member 80 (and, preferably, a pair of magnetic members 80) each magnetic member 80 having an elongate and generally rectangular configuration that is coupled to the front wall 22 of the deck member 20. Preferably, each magnetic member 80 extends downwardly toward a ground surface, such as the artificial turf surface, and is operative to magnetically attract and, therefore, pick up or extract any metallic materials that may be lying on the artificial turf that is being cleaned/groomed as will be described in more detail later. It is understood that metallic or magnetic materials collected by the magnetic members 80 may be periodically cleaned off with a swipe of a tool or a person's gloved hand, or the like.

(17) In a critical aspect, the pair of opposed sidewalls 24 each define at least two and, preferably, a plurality of channel openings 25 through which access from outside the deck member 20 and the interior area 27 beneath the deck member 20 may be accessed as will be described in further detail later. More particularly, the pair of sidewalls 24 define a pair of channel openings 25, respectively, the pair of channel openings 25 being adjacent the front wall 22 of the deck member 20. Further, the pair of sidewalls 24 may also define a pair of auxiliary openings 26, respectively, the pair of auxiliary openings 26 being positioned adjacent the rear wall 23. The purpose of the channel openings 25 and auxiliary openings 26 will be discussed later. It is understood that additional walls and frame structures not described above may be included in various embodiments.

(18) In another critical aspect, the deck member 20 of the turf grooming deck 10 may include a plurality of channels 30 mounted to a bottom surface 20a of the deck member 20, each channel 30 being configured to slidably receive a brush module, as will be explained in more detail below. More particularly, each channel 30 may include a pair of rails 31 that are parallel to one another and each having a linear configuration (FIG. 5a). In other words, each channel 30 provides a track along which a base of a respective brush member may travel along and as will be described in further detail later. Importantly, respective channels 30 are coupled to the bottom surface 20a of the deck member 20 and may be arranged in a diamond-shaped configuration as this configuration is most conducive to completely clean or remediate a turf surface. More particularly, the diamond-shaped configuration will allow respective pair of brush members to make contact with a turf surface at opposing angles (FIG. 4a).

(19) Similarly, an auxiliary channel 32 may be mounted to a bottom surface 20a of the deck member 20 in a position that is parallel with the rear wall 23 and that is intermediate (i.e., sandwiched between) the plurality of channels 30 and the rear wall 23. As will be explained below, a first auxiliary brush member 45 may include a first auxiliary base 46 having an elongate configuration so as to be slidably received upon the auxiliary channel 32, the first auxiliary brush member 45 being configured for insertion into or removal from a respective auxiliary opening 26. In an embodiment, the first auxiliary brush member 45 may include a plurality of first auxiliary tines 47 as shown particularly in FIGS. 6. Similarly, a second auxiliary brush member 60 may include a second auxiliary base 61 having an elongate configuration so as to be slidably received upon the auxiliary channel 32, the second auxiliary brush member 60 being configured for insertion into or removal from a respective auxiliary opening 26. In an embodiment, the auxiliary brush member 60 may include a plurality of tightly packed second auxiliary bristles 62 as shown particularly in FIGS. 5a and 5b.

(20) In another critical aspect, the turf grooming deck 10 includes at least one first brush module 40 and, preferably, a plurality of first brush modules 40. Each first brush module 40 has a configuration that is receivable and slidably movable along a respective channel 30 after having been inserted into the interior area 27 through a respective channel opening 25. More particularly, each first brush module 40 may include a first base member 42 having an elongate, linear, and planar surface configuration that is slidably movable along the rails 31 of a respective channel 30 after being inserted through a respective channel opening 25. It is understood that the movement of a first brush module 40 along a channel 30 is by manual exertion of a user. Further, each first brush module 40 includes a plurality of tines 41 as will be described in more detail later.

(21) Similarly, the turf grooming deck 10 includes at least one second brush module 50 and, preferably, a plurality of second brush modules 50. Each second brush module 50 has a configuration that is receivable and slidably movable along a respective channel 30 after having been inserted into the interior area 27 through a respective channel opening 25. More particularly, each second brush module 50 may include a second base member 52 having an elongate, linear, and planar surface configuration that is slidably movable along the rails 31 of a respective channel 30 after being inserted through a respective channel opening 25. Further, each second brush module 50 may include a plurality of tightly packed bristles 51 as will be described in more detail later. It is understood that the movement of a second brush module 50 along a channel 30 is by manual exertion of a user. It is understood that because the channels 30 and base members 42, 52 are mounted to the bottom surface 20 of the deck member 20, the first and second brush modules 40, 50 are actually upside down such that the tines 41 and bristles 51 extend downwardly toward and in contact with the ground surface as shown in the illustrations, i.e., with the artificial turf.

(22) It is understood that, in use, the plurality of first brush modules 40 must be slidably removed from the plurality of channels 30 before the plurality of second brush modules 50 and be inserted as will be described in greater detail later.

(23) The specific configurations and constructions of the first and second brush modules will now be discussed in detail. Each first brush module 40 includes at least one and, preferably, a plurality of metal tines 41, each tine 41 being coupled to and extending away from a top surface of a first base member 42 (FIG. 8). In an embodiment, each tine 41 may be coupled to the base member 42 using a combination of bolts and brackets or comparable fasteners as would be understood by persons of ordinary skill in the art. Preferably, each tine 41 has a linear and elongate configuration that, in use, will make contact with and intentionally disrupt the artificial turf surface. The plurality of tines 41 may generally define a longitudinal axis (a.k.a. a horizontal axis). In an embodiment, the plurality of tines 41 may be separated or segregated into groupings 41a, each grouping including a predetermined number of tines 41, such as groupings each having two tines or four tines. Preferably, each grouping 41a defines its own grouping axis that is offset from the overall longitudinal axis defined by the plurality of tines 41—such as being offset forwardly or rearwardly or even angularly (FIG. 8).

(24) By contrast, each second brush module 50 includes at least one and, preferably, a plurality of tightly packed bristles 51. Specifically, the bristles may be tightly packed synthetic push broom type bristles 51 (FIG. 5a). Again, the plurality of bristles 51 are configured to recondition and clean a surface of the turf as the brushes are moved across the turf surface.

(25) In another aspect, the deck member 20 includes at least one stop member 70 mounted and positioned adjacent each channel opening 25. In an embodiment, the stop member 70 may be in the form of a spring-loaded pin and, thus, movable between a compressed configuration allowing insertion of a respective brush member (FIG. 5b) and a deployed configuration not allowing insertion or removal of a respective brush member (FIG. 4a). More particularly, each stop member 70 is positioned between the proximal end of a respective channel 30 and a respective channel opening 25 and is configured to prevent an unintended outward sliding of a respective brush module. In other words, each stop member 70 has a shape configuration and profile sufficient to block passage of a respective base member of a respective brush module.

(26) In use, the deck member 20 is mounted to the frame of a lawn tractor 12 between its pairs of front and rear wheels and a manner substantially similar to mounting a deck configured to mow a lawn. Only in the case of the present invention, the deck member 20 conspicuously has no blade for cutting grass but, rather, has the plurality of channels 30, the pair of channel openings 25, and the plurality of first brush modules 40, and plurality of second brush modules 50. As described above, the plurality of first brush members 40 may be inserted through respective channel openings 25 into the interior area 27 of the deck member 20 and along the rails 31 of respective channels 30. When the lawn tractor is actuated (i.e., when the motor thereof is energized), the plurality of first brush members 40 are configured to firmly engage an artificial turf surface whereby to disrupt the rubber or rubber fragments of the artificial turf. Other components, including a vacuum, may be utilized for lifting or removing said fragments. Then, according to a preferred method of the present invention, the plurality of first brush members 40 may be individually and respectively removed from respective channels 30 via respective channel openings 25 and systematically replaced by the plurality of second brush members 50 via the same openings. Once again, the lawn tractor 12 may be engaged to traverse the artificial turf surface so that the plurality of bristles may be engaged upon the artificial turf surface so as to clean it thoroughly. Finally, the plurality of second brush members 50 may be individually removed via respective channel openings 25.

(27) It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
