Abstract

A stabilizer pad for use with stabilizer legs of a work machine is disclosed. The stabilizer pad may include a frame configured for attachment to the stabilizer leg of the work machine. The stabilizer pad may further include at least one resilient member including a plate member having one or more mounts. The resilient member may also include one or more resilient pads having longitudinal axes which are parallel to the plate member. The resilient pads may comprise at least one fiber reinforced elastomeric layer. A bottom or second surface of a resilient pad may define a continuous ground contact surface.

First claim

What is claimed is:

1. A resilient member for a stabilizer pad of a work machine, the resilient member comprising:
a plate member including one or more mounts configured for attachment to a stabilizer leg, the plate member defining a first plane;
a first resilient pad defining an elastomeric envelope which at least partially surrounds the plate member, the first resilient pad including a first surface from which the one or more mounts extend and a second surface opposite the first surface, the first resilient pad defining a second plane; and
a second resilient pad attached to the second surface of the first resilient pad, the second resilient pad defining a third plane;
wherein the first and second resilient pads include at least one fiber reinforced elastomeric layer; and
wherein the first, second, and third planes are parallel.

2. The resilient member of claim 1 , further comprising a continuous ground contact surface.

3. The resilient member of claim 1 , further comprising a fabric layer disposed between the first and second resilient pads.

4. The resilient member of claim 1 , wherein the second resilient pad comprises a first surface attached to the first resilient pad and a second surface opposite the first surface,
wherein the second surface of the second resilient pad is parallel to a ground surface when the resilient member is in contact with the ground surface.

5. The resilient member of claim 1 , wherein the elastomeric envelope comprises two elastomeric sheets attached together to surround the plate member.

6. The resilient member of claim 1 , wherein the elastomeric envelope comprises one elastomeric sheet secured around the plate member.

7. The resilient member of claim 1 , wherein the mounts are threaded bosses.

8. The resilient member of claim 1 , further comprising a third resilient pad including a first surface attached to the second resilient pad and a second surface opposite the first surface;
wherein the third resilient pad includes at least one fiber reinforced elastomeric layer.

9. The resilient member of claim 8 , wherein the second surface of the third resilient pad is parallel to the plate member.

10. A stabilizer pad for a work machine, the stabilizer pad comprising:
a frame attachable to a stabilizer leg, a resilient member, and a connector for securing the resilient member to the frame;
the resilient member comprising:
a plate member having one or more mounts configured for attachment to the frame;
a first resilient pad defining an elastomeric envelope which at least partially surrounds the plate member and one or more mounts, the first resilient pad having a first longitudinal axis; and
a second resilient pad attached to a second surface of the first resilient pad, the second resilient pad having a second longitudinal axis;
wherein the first and second resilient pads include at least one fiber reinforced elastomeric layer and the first and second longitudinal axes are parallel to the frame.

11. The stabilizer pad of claim 10 , wherein the elastomeric envelope comprises two elastomeric sheets attached together to surround the plate member.

12. The stabilizer pad of claim 10 , wherein the elastomeric envelope comprises one elastomeric sheet secured around the plate member.

13. The stabilizer pad of claim 10 , wherein the resilient member further comprises a fabric layer disposed between the first and second resilient pads.

14. The stabilizer pad of claim 10 , wherein a surface of the second resilient pad defines a continuous ground contact surface.

15. The stabilizer pad of claim 10 , wherein the resilient member further comprises a third resilient pad attached to the second resilient pad, the third resilient pad having a third longitudinal axis.

16. The stabilizer pad of claim 15 , wherein the resilient member further comprises a fabric layer disposed between the second and third resilient pads.

17. The stabilizer pad of claim 10 , wherein the resilient member further comprises an elastomeric coating which at least partially surrounds the plate member and first and second resilient pads.

18. The stabilizer pad of claim 17 , wherein the elastomeric coating defines a continuous ground contact surface which is parallel to the plate member.

19. The stabilizer pad of claim 10 , wherein the plate member defines a first plane, the first resilient pad defines a second plane, the second resilient pad defines a third plane, and wherein the first, second, and third planes are parallel.

20. A resilient member for use with a stabilizer leg of a work machine, the resilient member comprising:
a plate member including one or more mounts configured for attachment to the stabilizer leg;
a first resilient pad defining an elastomeric envelope which at least partially surrounds the plate member;
a second resilient pad attached to the first resilient pad;
a third resilient pad attached to the second resilient pad;
a first fabric layer disposed between the first and second resilient pads;
a second fabric layer disposed between the second and third resilient pads; and
an elastomeric coating at least partially surrounding the plate member and first, second, and third resilient pads;
wherein the second resilient pad is disposed between the first resilient pad and third resilient pad;
wherein the first, second, and third resilient pads include at least one fiber reinforced elastomeric layer;
wherein the first resilient pad has a first longitudinal axis, the second resilient pad has a second longitudinal axis, and the third resilient pad has a third longitudinal axis, the first, second, and third longitudinal axes being parallel to the plate member; and
wherein a second surface of the third resilient pad defines a ground contact surface that is parallel to the plate member.
