The aerating-roller attachment for riding lawn mower 100 (hereinafter invention) comprises a roller 200, a plurality of spikes 210, and a mounting bracket 280. The invention 100 may be coupled to a riding lawn mower via the mounting bracket 280 and may aerate a lawn. The riding lawn mower may pull the roller 200 behind the riding lawn mower and the roller 200 may rotate as the riding lawn mower moves. The plurality of spikes 210 may be pressed into the lawn and then withdrawn from the lawn as the roller 200 turns. The weight of the riding lawn mower may force the plurality of spikes 210 into the lawn leaving a plurality of aeration holes such that water, nutrients, and air may penetrate the lawn.
The roller 200 may be cylindrical and may rotate around a longitudinal axis 202. The longitudinal axis 202 may emerge from the roller 200 at the center of a left roller end 204 and at the center of a right roller end 206 and may be oriented parallel to the lawn. The plurality of spikes 210 may be dispersed on the roller 200 such that each of the individual spikes 220 comprising the plurality of spikes 210 may be oriented perpendicular to the longitudinal axis 202 of the roller 200.
The individual spike 220 may be defined by a distal spike end 224 and a proximal spike end 222. The distal spike end 224 may be coupled to the roller 200. The proximal spike end 222 may form a pointed tip such that the individual spike 220 may pierce the lawn.
The plurality of spikes 210 may be arranged into a plurality of spike clusters 230. An individual spike cluster 232 may be a subset of the plurality of spikes 210 that lie in the same plane that is perpendicular to the longitudinal axis 202. Said another way, all of the individual spikes 220 within the individual spike cluster 232 are located the same longitudinal distance from the left roller end 204 of the roller 200.
In some embodiments, the plurality of spikes 210 that are within the individual spike cluster 232 may be spaced radially such that the plurality of spikes 210 are distributed evenly around the longitudinal axis 202 at a separation angle 238. The separation angle 238 may be measured between a first spike 234 and a second spike 236 where the first spike 234 is adjacent to the second spike 236.
In some embodiments, the individual spike cluster 232 may comprise four of the individual spikes 220. In some embodiments, the individual spike cluster 232 may comprise seven of the individual spikes 220 such that the spacing between the plurality of aeration holes is reduced.
In some embodiments, the individual spike clusters 232 may be radially offset from each other by an offset angle 256. A first spike cluster 252 may be rotated by the offset angle 256 relative to a second spike cluster 254 such that the individual spikes 220 of the first spike cluster 252 do not longitudinally align with the individual spikes 220 of the second spike cluster 254. The offset angle 256 may be measured from a vertically oriented spike 258 of the first spike cluster 252 to a closest spike 260 of the second spike cluster 254.
The mounting bracket 280 may comprise an attachment plate 282 and a pair of mounting arms. The attachment plate 282 may be coupled to the riding lawn mower such that the roller 200 is positioned where the roller 200 may contact the lawn directly or indirectly via the plurality of spikes 210. The pair of mounting arms may project perpendicularly away from the attachment plate 282 to hold the roller 200 at a distance from the riding lawn mower such that the roller 200 and the plurality of spikes 210 may rotate without interference from the riding lawn mower. A left arm 294 may be coupled to the left end of the attachment plate 282 and a right arm 296 may be coupled to the right end of the attachment plate 282.
An individual mounting arm 286 selected from the left arm 294 and the right arm 296 may be defined by a proximal arm end 288 and a distal arm end 290. The proximal arm end 288 may couple to the attachment plate 282. The distal arm end 290 may comprise a pivot point 292. The roller 200 may couple to the pivot points 292 of the pair of mounting arms such that the longitudinal axis 202 of the roller 200 passes through the pivot points 292.
In some embodiments, the roller 200 may be made of plastic, rubber, composite resins, or combinations thereof.
In use, the mounting bracket 280 may be coupled top the riding lawn mower such that the plurality of spikes 210 press into the lawn. As the riding lawn mower moves forward, the roller 200 may rotate and each rotation of the roller 200 may press the plurality of spikes 210 into the lawn. The riding lawn mower may be driven over the lawn leaving the plurality of aeration holes behind the riding lawn mower.
Unless otherwise stated, the words “up”, “down”, “top”, “bottom”, “upper”, and “lower” should be interpreted within a gravitational framework. “Down” is the direction that gravity would pull an object. “Up” is the opposite of “down”. “Bottom” is the part of an object that is down farther than any other part of the object. “Top” is the part of an object that is up farther than any other part of the object. “Upper” may refer to top and “lower” may refer to the bottom. As a non-limiting example, the upper end of a vertical shaft is the top end of the vertical shaft.
As used herein, “align” may refer to the placement of two or more components into positions and orientations which either arranges the components along a straight line or within the same plane or which will allow the next step of assembly to proceed. As a non-limiting example, the next step of assembly may be to insert one component into another component, requiring alignment of the components.
As used herein, the words “couple”, “couples”, “coupled” or “coupling”, may refer to connecting, either directly or indirectly, and does not necessarily imply a mechanical connection.
As used in this disclosure, the terms “distal” and “proximal” may be used to describe relative positions. Distal refers to the object, or the end of an object, that is situated away from the point of origin, point of reference, or point of attachment. Proximal refers to an object, or end of an object, that is situated towards the point of origin, point of reference, or point of attachment. Distal implies ‘farther away from’ and proximal implies ‘closer to’. In some instances, the point of attachment may be the where an operator or user of the object makes contact with the object. In some instances, the point of origin or point of reference may be a center point, a central axis, or a centerline of an object and the direction of comparison may be in a radial or lateral direction.
As used herein, the word “longitudinal” or “longitudinally” may refer to a lengthwise or longest direction.
As used herein, the word “pivot” may include any mechanical arrangement that allows for rotational motion. Non-limiting examples of pivots may include hinges, holes, posts, dowels, pins, points, rods, shafts, balls, and sockets, either individually or in combination.
As used in this disclosure, “vertical” may refer to a direction that is parallel to the local force of gravity. Unless specifically noted in this disclosure, the vertical direction is always perpendicular to horizontal.
