SUMMARY
Examples of such patents include: U.S. Patent 3,666,327 (Padilla) entitled "Track Shoe Protector"; U.S.
Patent 4,068,905 (Black et al) entitled "Detachable Road Protecting Device For Tracked Vehicles"; U.S. Patent 5,388,900 (Suzuki) entitled "Crawler Pad"; U.S. Patent 5,769,511 (Hattori) entitled "Crawler Track Shoe Cover For Protection Of Road Surfaces";
U.S. Patent 6,213,573 (Nakayama) entitled "Rubber Pads"; and U.S. Patent 6,412,888 (Miyoshi) entitled "Rubber Pad and Lock Pin For Iron Crawler Belt". What is required is a detachable cushioning pad that is easily attached and detached, can fit more than one size of track and is sufficiently robust to maintain its position when rocks or other obstacles are encountered during movement.
SUMMARY
[0004] There is provided a detachable cushioning pad for a tracked vehicle including an elongated body having a longitudinal axis, a top surface, a bottom surface, and opposed ends.
The body has an interior surface that defines at least one interior cavity with openings at the opposed ends in communication with the at least one interior cavity. A
cushioning pad is mounted on the top surface of the body. Clamping members are provided, with each of the clamping members having a track engaging end, a remote end and a shank extending between the track engaging end and the remote end. The remote end and a portion of the shank of each clamping member extends through one of the openings at the opposed ends of the body into the interior cavity. The clamping members are movable along the longitudinal axis to selectively position the track engaging end of each of the clamping members. A
lock is positioned within the at least one interior cavity of the body for locking the clamping members in a selected axial portion. The lock has a quick release mechanism on an exterior of the body.
The detachable cushioning pad, as described above, has the lock protected from damage within the body and yet it remains easily adjustable to suit installation requirements.
The particular means for locking the clamping members in a selected axial position, which will hereafter be further, described uses a locking wedge acting upon the shank of the clamping members. The locking wedge has a locking position and a release position. A spring is used to bias the locking wedge into the locking position. An external release mechanism is provided. When activated, the release mechanism overcomes the biasing force of the spring and moves the locking wedge to the release position.

Structure and Relationship of Parts:
Structure and Relationship of Parts:
[0007] Referring to FIG. 1 and FIG. 2, a detachable cushioning pad for a tracked vehicle 10 includes an elongated body 12 which has a longitudinal axis 14, shown in FIG. 6, a top surface 16, a bottom surface 18 and opposed ends 20. Referring to FIG. 6, body 12 has an interior surface 22 that defines an interior cavity 24 with two openings 33 and 35 at each of the opposed ends 20 in communication with interior cavity 24. Referring to FIG. 3, a cushioning pad 26 is mounted on top surface 16 of the body 12.
[0008] Referring to FIG. 6, clamping members 28 each have a track engaging end 30, a remote end 32 and a shank 34 extending between the track engaging end 30 and the remote end 32. Remote end 32 and a portion of the shank 34 of each clamping member 28 extends through one of the openings 33 at opposed ends 20 of body 12 into interior cavity 24.
Clamping members 28 are movable along the longitudinal axis 14 to selectively position track engaging end 30 of each clamping members 28. A stiffener 31 is positioned at track engaging end 30 of clamping member 28. A stop 29 is positioned at remote end 32 of each clamping member 28 to prevent remote end 32 of clamping member 28 from being withdrawn through one of openings 33 at opposed ends 20 of body 12.

A stop 29 is positioned at remote end 32 of each clamping member 28 to prevent remote end 32 of clamping member 28 from being withdrawn through one of openings 33 at opposed ends 20 of body 12.
[0009] Referring to FIG. 8, a lock, generally indicated by reference numeral 36, is positioned within the interior cavity 24 of body 12 for locking clamping members 28 in a selected axial position. Lock 36 includes a locking wedge 38, which acts upon shank 34 of clamping members 28. Locking wedge 38 has a locking position and a release position. A
spring 40 biases locking wedge 38 into the locking position. Biasing spring 40 has a first end 42 housed in a spring pocket 44 and a second end 46 acting upon the locking wedge 38. A
quick release mechanism, generally indicated by reference numeral 48, is located on an exterior of body 12. Release mechanism 48 includes an axially aligned shaft 50which extends through one of openings 35 at opposed ends 18 of body 12 and movable axially relative to the body 12. Shaft 50 has a first end 52 accessible from exterior of the body 12 and a second end 54 extending into interior cavity 24. Locking wedge 38 is mounted in an inclined orientation to shaft 50. In order to facilitate locking wedge 38 being positioned in an inclined orientation, second end 54 of shaft 50 is bent. A manual input button 56 is provided at first end 52 of shaft 52. A force is applied manually to input button 56 axially moves the shaft 50 overcomes the biasing force of spring 40 and moves locking wedge 38 to the release position.

A force is applied manually to input button 56 axially moves the shaft 50 overcomes the biasing force of spring 40 and moves locking wedge 38 to the release position.
[0010] Referring to FIG. 2, bottom 18 of body 12 has a hollow 58 to overlie topographical profiles on an endless track. Lateral movement restraint members 60 depend from bottom 18 of body 12 to engage topographical profiles on the endless track and retard lateral movement.
Operation:
Operation:
[0011] Referring to FIG. 6, detachable cushioning pad for a tracked vehicle 10 is placed on a track such that bottom surface 18 of body 12 is adjacent the track and restraint members 60 engage the track. Manual input button 56 on release mechanism 48 on an exterior of body 12 is pressed to move shaft 50 to overcome the biasing force of spring 40 and move locking wedge 38 to the released position. Once locking wedge 38 is in the release position, the length of clamping members 28 may be adjusted by pulling or pushing clamping members 28 axially through openings 33 at opposed ends 20 of body 12. Stops 29 at remote end 32 of each clamping member 28 prevents remote end 32 of clamping member 28 from being withdrawn through openings 33 at opposed ends 20. Clamping members 28 are positioned with track engaging end 30 securely engaging the track. Once clamping members 28 are in the desired location, button 56 on release mechanism 48 is released and the biasing force of spring 40 returns locking wedge 38 to the locking position.
Advantages:
[0012] Sensitive components, such as lock 26 and biasing spring 40 are protected within housing 12, which makes detachable cushioning pad 10 more robust. Clamping members 28 can be adjusted to fit different widths of track. This adjustability facilitates use with different sizes and makes of track.
