Claims
- 1. An apparatus comprising:a boom quick coupler and a boom cylinder quick coupler, said boom quick coupler comprising: a body defining at least one bore about a transverse boom pivot axis, said bore adapted for selective alignment with a transverse bore defined in an associated boom; a first transversely extending open recess defined in said body about a first transverse axis that is parallel to said transverse boom pivot axis, said first recess adapted for selective receipt of a first associated pin affixed to an associated excavator; a second transversely extending open recess defined in said body about a second transverse axis that is parallel to the first transverse axis, said second recess adapted for selective receipt of a second associated pin affixed to the associated excavator; and, said boom cylinder quick coupler comprising: a boom cylinder coupler body defining a bore about a transverse cylinder pivot axis, said coupler body adapted for pivotable connection to first and second associated fluid cylinders by insertion of a pin through said bore and through aligned bores defined in first and second members respectively connected to said first and second associated fluid cylinders; a first pin-receiving recess defined in said boom cylinder coupler body about a third transverse axis that is parallel to said transverse cylinder pivot axis, said first pin-receiving recess adapted for selective receipt of a first associated pin connected to the associated boom; and, a second pin-receiving recess defined in said boom cylinder coupler body about a fourth transverse axis that is parallel to said first transverse axis, said second pin-receiving recess adapted for selective receipt of a second associated pin connected to the associated boom; and, a boom-receiving channel that intersects said first and second pin-receiving recesses defined in said boom cylinder coupler body, said boom-receiving channel adapted for receipt of at least a portion of the associated boom therein when said first and second recesses defined in said boom cylinder coupler body respectively receive the first and second associated pins connected to the boom.
- 2. The quick coupler apparatus as set forth in claim 1, wherein said first and second transversely extending open recesses of said boom quick coupler are conformed in said body so that said second recess is positioned to receive the second associated pin when the first associated pin is seated in said first recess.
- 3. The quick coupler apparatus as set forth in claim 1, wherein said first and second transversely extending open recesses are each defined to include respective first and second open mouths that open in transverse directions relative to each other.
- 4. The quick coupler apparatus as set forth in claim 3, wherein said first transversely extending open recess opens in an end region of said body and wherein said second transversely extending open recess opens in a bottom region of said body, said end and bottom regions of said body arranged transverse relative to each other.
- 5. The quick coupler apparatus as set forth in claim 1, wherein said body comprises:first and second parallel, spaced-apart sidewalls, wherein said at least one bore comprises first and second cylindrical bores defined respectively through said first and second sidewalls, said first and second bores aligned with each other on said transverse boom pivot axis.
- 6. The quick coupler apparatus as set forth in claim 5, wherein said first and second sidewalls define therebetween a channel conformed to accommodate a proximal end of the associated boom.
- 7. The quick coupler apparatus as set forth in claim 1, further comprising:a boom lock mechanism connected to said body and including a lock member adapted for selective movement between a retracted position and an extended position, said lock member at least partially spanning an open mouth of said second transversely extending open recess when in the extended position to thereby capture a second associated pin in the second transversely extending open recess.
- 8. The quick coupler apparatus as set forth in claim 1, wherein said first and second transversely extending open recesses are at least partially defined by first and second partially cylindrical surfaces centered on said first and second transverse axes, respectively.
- 9. In combination with an excavator that includes: (i) a boom; (ii) first and second boom cylinders; (iii) first and second excavator pins connected to the excavator; and, (iv) first and second boom pins connected to the boom, a system for releasably connecting the boom to the excavator and for releasably connecting the first and second boom cylinders to the boom, said system comprising:a boom quick coupler and a boom cylinder quick coupler, said boom quick coupler comprising: a body defining at least one bore about a transverse boom pivot axis, said bore adapted for selective alignment with a transverse bore defined in an associated boom; a first transversely extending open recess defined in said body about a first transverse axis that is parallel to said transverse boom pivot axis, wherein the first excavator pin is received in the first transversely extending recess; a second transversely extending open recess defined in said body about a second transverse axis that is parallel to the first transverse axis, wherein the second excavator pin is received in the second transversely extending recess; said boom cylinder quick coupler comprising: a boom cylinder coupler body defining a bore about a transverse cylinder pivot axis, said coupler body connected to said first and second fluid cylinders by insertion of a mounting pin through said bore and through aligned bores defined in first and second members respectively connected to said first and second fluid cylinders; a first pin-receiving recess defined in said boom cylinder coupler body about a third transverse axis that is parallel to said transverse cylinder pivot axis, wherein the first boom pin is received in said first pin-receiving recess; and, a second pin-receiving recess defined in said boom cylinder coupler body about a fourth transverse axis that is parallel to said first transverse axis, wherein the second boom pin is received in said second pin-receiving recess.
- 10. The quick coupler apparatus as set forth in claim 1, further comprising:at least one boom cylinder lock mechanism connected to said boom cylinder coupler body, said at least one boom cylinder lock mechanism including a boom cylinder lock member that is selectively movable between a retracted position and an extended position, said boom cylinder lock member, when extended, at least partially obstructing said second pin-receiving recess defined in said boom cylinder coupler body.
- 11. The quick coupler apparatus as set forth in claim 1, wherein said first and second pin-receiving recesses of said boom cylinder coupler body define partially cylindrical inner regions centered on said third and fourth transverse axes, respectively.
