Illustrative Embodiment
An illustrative embodiment of a top surface mover 10 is shown engaged with a tractor 12 in FIG. 1. The illustrative embodiment of a top surface mover 10 may be used to properly position a top surface piece 18, as will be described in detail below. Generally, the top surface mover 10 may comprise a vertical portion 30, a horizontal portion 40, and an engagement pad 20. The vertical portion 30 may include a vertical receiver 32 and a vertical beam 34 moveable with respect to the vertical receiver 32 along the longitudinal axis thereof. Similarly, the horizontal portion 40 may include a horizontal receiver 42 and a horizontal beam 44 moveable with respect to the horizontal receiver 42 along the longitudinal axis thereof.
The movement of the vertical beam 34 with respect to the vertical receiver 32 and/or the horizontal beam 44 with respect to the horizontal receiver 42 may be accomplished via one or more actuators 16, as shown in the illustrative embodiment of the top surface mover 10. The actuators 16 may be powered via a pressurized fluid originating at the tractor 12 and transported to the top surface mover 10 via fluid conduit 15. If actuators 16 are used, they may be positioned in the vertical receiver 32 and horizontal receiver 42, respectively, such that a first end of each actuator 16 is engaged with the receiver 32, 42 and the second end is engaged with the beam 34, 44.
In other embodiments the actuators 16 may be powered via electricity or any other suitable motive force. Furthermore, in still other embodiments of the top surface mover 10 the movement of the vertical beam 34 with respect to the vertical receiver 32 and/or the horizontal beam 44 with respect to the horizontal receiver 42 may be manually accomplished. Accordingly, the top surface mover 10 as disclosed and claimed herein is not limited by the structure and/or method used to cause the vertical beam to move with respect to the vertical receiver 32 and/or the horizontal beam 44 to move with respect to the horizontal receiver 42.
The illustrative embodiment of the top surface mover 10 is shown with the vertical beam 34 and horizontal beam 44 fully extended in FIG. 2A and the beams 34, 44 fully retracted in FIG. 2B. The optimal distance of travel of the vertical beam 34 with respect to the vertical receiver 32 and/or horizontal beam 44 with respect to the horizontal receiver 42 will vary from one application of the top surface mover 10 to the next, and is therefore in no way limiting to the scope thereof.
As clearly shown in FIGS. 1-2B, one end of the horizontal beam 44 may be cooperatively engaged with the vertical receiver 32 at a horizontal/vertical interface 45. In this configuration, extension of the horizontal beam 44 causes the vertical portion 30 to move in the same direction, and retraction of the horizontal beam 44 causes the vertical portion 30 to move in the same direction. It is contemplated that the horizontal portion 40 and engagement pad 20 may be configured so that the inside edge of the engagement pad 20 may be positioned inside the outer edge of the wheels of the prime mover. As is evident from the current disclosure, the top surface mover 10 may be configured such that the engagement pad 20 is moveable with respect to the prime mover in at least two dimensions.
A mounting member 46 may be engaged with the horizontal portion 40 to cooperatively engage the top surface mover 10 with a prime mover (e.g., tractor 12). In the illustrative embodiment of the top surface mover 10, the mounting member 46 may comprise a plate secured to the horizontal receiver 42 with apertures therein. Fasteners (such as bolts) may be used to align apertures in the mounting member 46 to apertures in the prime mover and thereby engage the top surface mover 10 with the prime mover. If additional robustness is required, one or more braces 14 may be used to engage the mounting member 46 with the horizontal portion 40. Additionally, a portion of the horizontal receiver 42 may be engaged with the prime mover if more rigidity, strength, and/or robustness is required. Any structure and/or method suitable for the particular application of the top surface mover 10 may be used to engage the top surface mover 10 with a prime mover, and therefore the specific structure and/or method used therefor in no way limits the scope of the top surface mover as disclosed and claimed herein.
An engagement pad 20 may be cooperatively engaged with one end of the vertical beam 34 at a connector portion 22 of the engagement pad 20. The connector portion 22 may rigidly engage with engagement pad 20 with the vertical beam 34, or it may be configured to allow a small amount of movement (e.g., 1-10 degrees of slope) between the engagement pad 20 and the vertical beam 34. The engagement pad 20 may be formed with a surface engager 24 on the bottom surface thereof, and a plurality of engagement protrusions 24a may extend outward from the surface engager. The optimal number of protrusions 24a will vary from one embodiment of the top surface mover 10 to the next, as will the specific distance from which the surface engager 24 the protrusions 24a extend. However, it is contemplated that in some applications the optimal length of the engagement protrusions 24a will be such that when the surface engager 24 is fully engaged with a top surface piece 18, the distal ends of the engagement protrusions 24a do not contact the ground surface 17. This dimension will depend on the thickness of the top surface piece 18, but in most applications will be between 0.1 inches and 2.0 inches. In this configuration, extension of the vertical beam 34 causes the engagement pad 20 to move in the same direction, and retraction of the vertical beam 34 causes the engagement pad 20 to move in the same direction.
Illustrative Method of Use
Having described a preferred embodiment of the top surface mover 10, one method of using the top surface mover 10 will now be described. Generally, the top surface mover 10 may be adapted to properly position a top surface piece 18. The illustrative method of use described herein is generally directed toward a top surface piece 18 configured as a piece of grass sod. However, the present disclosure is not so limited and includes embodiments configured for positioning any top surface piece 18 for which a top surface mover 10 may be advantageous.
Generally, when laying sod, sections of sod are unrolled onto the ground surface 17 and positioned adjacent on another to close all top surface gaps 19 that may exist between two top surface pieces 18. FIG. 4A shows a top surface piece 18 after it has been unrolled and generally positioned adjacent properly placed top surface piece 18. As shown, a top surface gap 19 exists between the unrolled top surface piece 18 and the properly positioned top surface piece 18.
The user may move the prime mover until the engagement pad 20 is approximately centered over the top surface piece 18. This may require extending and/or retracting the horizontal beam 44 and/or moving the prime mover forward or backward. Once the user is satisfied with the position of the engagement pad 20 with respect to the unrolled top surface piece 18, the user may extend the vertical beam 34 so that the surface engager 24 touches the top surface piece 18 and the engagement protrusions 24a extend into the top surface piece 18.
Once the engagement pad 20 is fully engaged with the top surface piece 18, the user may extend or retract the horizontal beam 44 as needed to slide the top surface piece 18 along the ground surface 17 with the top surface 10 mover until the top surface gap 19 reaches a predetermine value wherein the predetermine value is further defined as in the range of 0-2 inches. In this way, the top surface mover 10 is functional to position the top surface piece 18 from side to side. When the engagement pad 20 is fully engaged with the top surface piece 18, the user may also adjust the position of the top surface piece 18 in the fore-aft dimension by moving the prime mover forward or backward.
After the top surface piece 18 is properly positioned, the user may retract the vertical beam 34, thereby disengaging the engagement pad 20 and the top surface piece 18. At this point, the user may move to the next top surface piece 18 and repeat any necessary steps required to properly position that top surface piece 18 and close/adjust any top surface gaps 19 associated therewith. Using this method, the top surface gaps 19 around the various top surface pieces 18 may be virtually invisible, leading to improved outcome in ground surface coverage, affixation to the ground surface, 17 and improved aesthetics.
Having described the preferred embodiments, other features of the top surface mover 10 and method of use will undoubtedly occur to those versed in the art, as will numerous modifications and alterations in the embodiments as illustrated herein, all of which may be achieved without departing from the spirit and scope of the top surface mover 10 and/or method of use as disclosed herein. It should be noted that the top surface mover 10 and method of use are not limited to the specific embodiments pictured and described herein, but are intended to apply to all similar apparatuses and methods for positioning a top surface piece. Modifications and alterations from the described embodiments will occur to those skilled in the art without departure from the spirit and scope of the top surface mover 10 and/or method of use.
