There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A plurality of wheels 30 is each rotatably coupled to the housing 12 thereby facilitating the housing 12 to be rolled along a support surface 32. Each of the wheels 30 is positioned on the perimeter wall 28 of the deck portion 16 of the housing 12, and each of the wheels 30 is aligned with a respective one of four corners 34 of the perimeter wall 28. A handle 36 is pivotally coupled to and angles upwardly from the housing 12. The handle 36 can be gripped by a child such that the child can push the housing 12 in the convention of a lawn mower. The handle 36 has a central portion 38 which is perpendicularly oriented between a pair of outward portions 40. Each of the outward portions 40 has a distal end 22 with respect to the central portion 38 and each of the outward portions 40 is pivotally engaged to a respective engagement point on the upper wall 26 of the deck portion 16 of the housing 12 at a point located adjacent to the distal end 22 of the outward portions 40.
A drive unit 42 is movably integrated into the housing 12 and the drive unit 42 is in mechanical communication with at least one of the wheels 30. The drive unit 42 is rotated when the at least one wheel is rotated. The drive unit 42 comprises a primary gear 44 that is positioned around an axle 46 extending between a rear pair of the wheels 47. In this way the primary gear 44 rotates about a rotational axis of the axle 46 when the rear pair of wheels 48 rotates. The primary gear 44 has a front face 50 and the front face 50 has a plurality of teeth 52 extending away from the front face 50. Moreover, the teeth 52 are spaced apart from each other and are distributed around a perimeter of the front face 50 such that the teeth 52 encircle the rotational axis of the axle 46.
The drive unit 42 includes a first pulley 54 that is rotatably disposed on a bottom side 56 of the upper wall 26 of the deck portion 16 of the housing 12. The drive unit 42 includes a shaft 58 that has an upper end 60 and a lower end 62, and the shaft 58 is rotatably disposed in the shaft well 24 in the distal end 22 of the shaft receiver 20. Additionally, the upper end 60 is positioned within the shaft well 24 and the lower end 62 is spaced downwardly from the distal end 22 of the shaft receiver 20. The drive unit 42 includes a second pulley 64 that is positioned around the shaft 58 such that the second pulley 64 rotates the shaft 58 about an axis extending through the upper end 60 and the lower end 62. The drive unit 42 includes a belt 66 extending around the first pulley 54 and the second pulley 64 such that the second pulley 64 is rotated when the first pulley 54 rotates.
The drive unit 42 includes a secondary gear 68 that has an upper surface 70 and an outer surface 72, and the upper surface 70 is coupled to the second pulley 64. The outer surface 72 tapers inwardly from the upper surface 70, and a plurality of teeth 74 is integrated into the outer surface 72 and is distributed around the outer surface 72. The plurality of teeth 74 on the outer surface 72 engages the plurality of teeth 52 on the front face 50 of the primary gear 44 such that the secondary gear 68 rotates the second pulley 64 when the primary gear 44 rotates. The primary gear 44 has a greater number of teeth than does the secondary gear 68 such that the rotational speed of the secondary gear 68 is increased with respect to the rotational speed of the primary gear 44. Additionally, the first pulley 54 has a diameter that is greater than the diameter of the second pulley 64. In this way the rotational speed of the second pulley 64 is significantly increased beyond the rotational speed of the pair of rear wheels 47.
A trimming unit 76 is coupled to the drive unit 42 and the trimming unit 76 is rotated when the drive unit 42 is rotated. The trimming unit 76 is directed downwardly on the housing 12 thereby facilitating the trimming unit 76 to trim the lawn when the housing 12 is pushed along the lawn. The trimming unit 76 comprises a trimming head 78 that has a top surface 80 and a perimeter surface 82. The top surface 80 is coupled to the lower end 62 of the shaft 58 such that the trimming head 78 is rotated when the shaft 58 rotates, and the shaft 58 is centrally positioned on the top surface 80. The trimming unit 76 includes a plurality of filaments 84 that is each coupled to and extends away from the perimeter surface 82 of the trimming head 78. In this way each of the filaments 84 can strike grass 86 growing in the lawn when the trimming head 78 is rotated thereby trimming the grass 86.
In use, the handle 36 is gripped to push the housing 12 along the lawn. The rear wheels 30 drive the drive unit 42 to rotate the trimming unit 76. In this way the filaments 84 on the trimming head 78 are rapidly rotated to trim grass 86 growing in the lawn. Thus, a child can practice employing a powered lawnmower without the risk of being injured while still actually trimming the grass 86. Moreover, the trimming unit 76 is motionless when the rear wheels 30 are not rotating, thereby facilitating the trimming unit 76 to be harmless.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
