Abstract
A ground treatment device including a housing fabricated from at least one injection molded part. An axle with a ground treatment attachment mounted thereto can be rotatably secured to opposing sides of the housing. The housing can include a gear housing structure which is configured to house gears for enabling operation of the ground treatment attachment using a power tool. An upper frame can be secured to opposing sides of the housing. The ground treatment attachment can be configured to cultivate the ground.
Claims9
A ground treatment device comprising:
- a metallic upper frame, being a single-piece metallic support and including a horizontal portion;
- a first vertical portion and a second vertical portion;
- and a first curved portion and a second curved portion forming transitions between the horizontal portion and the first and second vertical portions, respectively;
- a housing being a single injection molded piece comprising:
- a elevated front portion;
- an elongated back portion;
- a curved top surface extending between the elevated front portion and the elongated back portion;
- opposing exterior sides, the opposing exterior sides including a first exterior side and a second exterior side, each exterior side including a bearing slot for mounting an axle thereto;
- a frame mounting structure located on the first exterior side of the housing, the frame mounting structure extending vertically upward above a highest point of the curved top surface and having a first socket on an exterior vertical surface of the first exterior side, the first socket being a cavity for securing the frame mounting structure to a first vertical surface of the first vertical portion of the metallic upper frame;
- and
- a gear housing structure located on the second exterior side of the housing, wherein the gear housing structure has an outward facing interior region, the gear housing structure extending vertically above a highest point of the curved top surface and having a second socket on an exterior vertical surface of the second exterior side, the second socket being a cavity for securing the gear housing structure to a second vertical surface of the second vertical portion of the metallic upper frame;
- and
- an axle located on an interior portion of the housing, wherein the axle is rotatably mounted to the bearing slots on the opposing exterior sides, and wherein the axle includes a ground treatment attachment mounted thereto,
- wherein the single injection molded piece exposes the ground treatment attachment in a direction that is opposite a user when the ground treatment device is being used by the user and covers the ground treatment attachment in a vertical direction and in an opposing direction that is closest to the user when the ground treatment device is being used by the user.
