Abstract

Disclosed herein are self-guiding roller devices and system for compressing a medium. In one aspect, the roller devices and systems include: an attachment frame having a first pivot portion and configured to connect to a powered machine; a roller assembly including at least one rotatable roller component and at least one roller frame having a second pivot portion being configured to connect to the first pivot portion; and a pivot member configured to connect the first and second pivot portions, the roller assembly being able to rotate 360-degrees about the attachment frame while being driven from behind by an attached powered machine. Also disclosed herein are methods of using the disclosed roller devices and systems.

Claims

1. A roller device for attachment to a powered machine, the roller device comprising:

a) an attachment frame configured to detachably connect to a front portion of a powered machine, the attachment frame comprising;

i) at least one support arm having first and second opposed ends, the first end having a first pivot portion configured to receive a pivot member, and the second end being configured to connect to the front portion of the powered machine;

b) a roller assembly comprising;

i) at least one rotatable roller component;

ii) at least one roller frame having first and second ends, the first end being rotatably connected to a first end of the roller component with a rotating means configured to allow rotation of the roller component, the second end being rotatably connected to a second end of the roller component using a rotating means configured to allow rotation of the roller component, and the roller frame having a second pivot portion being configured to connect to the first pivot portion; and

c) a pivot member connecting the first and second pivot portions;

wherein the roller assembly can rotate 360-degrees about the attachment frame while being driven from behind by an attached powered machine;

wherein the roller assembly is configured to be pulled forward in a desired path upon forward movement of an attached powered machine;

wherein the first pivot portion is configured to rotate the roller assembly around a first pivot axis, and the second pivot portion is configured to pivot the roller assembly about a second pivot axis;

wherein a vertical axis on which the roller component rotates is spaced apart behind from a vertical axis of the pivot member on which the roller assembly rotates; and

wherein the roller component follows behind the first pivot portion of the attachment frame.

2. The device of claim 1, wherein the roller assembly tracks behind the pivot member and is configured to maintain alignment by pivoting about the pivot member at the second pivot portion.

3. The device of claim 2, wherein the first pivot portion comprises a first pivoting means configured to rotate the roller assembly around the first pivot axis, and the second pivot portion comprises a second pivoting means configured to pivot the roller assembly around the second pivot axis.

4. The device of claim 3, wherein the second pivot axis is parallel to a movement direction and corresponds with a contact point between the roller component and a surface elevation of a medium thereby positioning the second pivot axis correspondingly to the surface elevation at the point of contact.

5. The device of claim 3, wherein the second pivot axis is parallel to a movement direction;

and wherein the roller device is configured to maintain the second pivot axis substantially aligned with a vertical plane parallel to the movement direction and substantially corresponding with a contact point between the roller component and a surface upon which the roller component is supported; and

wherein the first pivot axis will substantially remain at a fixed point relative to the roller component as the first pivoting means rotates about its axis.

6. The device of claim 3, wherein when the attachment frame and roller assembly are connected, the roller frame is oriented to the ground at an angle of from about 15 to about 75 degrees.

7. The device of claim 6, further comprising a powered machine connected to the attachment frame.

8. The device of claim 7, wherein the powered machine comprises a lawn maintenance machine, walk behind mower, riding mower, tractor, skid-steer, motor driven vehicle, all-terrain vehicle (ATV), or utility task vehicle (UTV), or powered track type machine.

9. A method for compressing a medium, the method comprising:

a) providing the device of claim 7; and

contacting a medium with the roller component to thereby compress the medium.

10. The device of claim 1, wherein the attachment frame comprises two support arms, wherein the first ends are connected to the first pivot portion, and wherein the second ends are configured to detachably connect to a first and second front portions of the powered machine.

11. The device of claim 1, wherein the second end of the support arm further comprises a third pivot portion rotatably connected to a portion of the powered machine by a pivot member.

12. The device of claim 1, wherein the first and second pivot portions comprise an aperture or port for receiving a pivot member.

13. The device of claim 1, wherein the roller device is not dependent upon the turning radius of the powered machine to which it is attached.

14. The device of claim 1, further comprising a plurality of roller components.

15. The device of claim 14, wherein each roller component is configured to rotate independent of other roller components.

16. A medium compressing system, the system comprising:

a) a powered machine

b) a roller device comprising;

i) an attachment frame configured to detachably connect to the powered machine, the attachment frame comprising;

1. at least one support arm having first and second opposed ends, the first end having a first pivot portion configured to receive a pivot member, and the second end being configured to connect to a portion of the powered machine;

ii) a roller assembly comprising;

1. at least one rotatable roller component;

2. at least one roller frame having first and second ends, the first end being rotatably connected to a first end of the roller component with a rotating means configured to allow rotation of the roller component, the second end being rotatably connected to a second end of the roller component using a rotating means configured to allow rotation of the roller component, and the roller frame having a second pivot portion being configured to connect to the first pivot portion; and

iii) a pivot member connecting the first and second pivot portions;

wherein the roller assembly can rotate 360-degrees about the attachment frame while being driven by the powered machine;

wherein the roller assembly is configured to be pulled forward in a desired path upon forward movement of an attached powered machine;

wherein when the first and second pivot portions are connected by the pivot member;

and wherein the roller assembly tracks behind the pivot member and is configured to maintain alignment by pivoting about the pivot member at one or more pivot portions.

17. The system of claim 16, wherein the attachment frame comprises two support arms, wherein the first ends are connected to the first pivot portion, and wherein the second ends are configured to detachably connect to a first and second front portions of the powered machine.

18. The system of claim 16, wherein the first pivot portion comprises a first pivoting means configured to rotate the roller assembly around a first pivot axis, and the second pivot portion comprises a second pivoting means configured to pivot the roller assembly around a second pivot axis.

19. The system of claim 18, wherein the second pivot axis is parallel to a movement direction;

and wherein the roller device is configured to maintain the second pivot axis substantially aligned with a vertical plane parallel to the movement direction and substantially corresponding with a contact point between the roller component and a surface upon which the roller component is supported;

wherein the first pivot axis will substantially remain at a fixed point relative to the roller component as the first pivoting means rotates about the first pivot axis.

20. The system of claim 19, wherein the second pivot point is positioned below the first pivot point;

and thereby allowing the roller device to contour to a surface elevation of a medium being compressed independent of the position of the powered machine in relationship to the contour of the surface medium.
