Appl. No.:

10/454704

Inventors:

Kenneth R. Friedland - Centennial CO, US
Charles Leroy Welch - Westminster CO, US
Donna Kelleen Darnell - Boulder CO, US

Assignee:

Construction Technology, Inc. - Denver CO

International Classification:

E02F 7/04

US Classification:

414724, 37405, 414912

Abstract:

A fork lift attachment for multi-purpose buckets that is easily installed and secured. The mechanism fits under the bucket and is supported by a slot on the top side of the tine and a latch at the heel of the tine. The latch is tightened causing the fork lift attachment to be cinched onto the bucket. A security chain readily and visibly secures the latch so as to prevent the fork lift attachments from being dislodged even if the hydraulics open the bucket.

Appl. No.:

6/938423

Inventors:

Paul T. St. Louis - Littleton CO

Assignee:

Consolidated Technologies, Inc. - Denver CO

International Classification:

B60D 108

US Classification:

285 39

Abstract:

This invention relates to a peripheral connector for a standard coupler, which permits the coupler to be remotely connectable and disconnectable. A male unit and a female unit of the invention enclose a male half and a female half of the coupler, respectively, and cover them with protective boots. A female unit projects an assembly, thereby opening the boot covering the female coupler half. The projected assembly pushes against portions of the male unit, opening the boot covering the male unit, and connecting the coupler. Disconnection is accomplished by moving the projected assembly in the opposite direction.

Abstract:

A hitch apparatus for detachably connecting a bucket to a power operated boom of a self propelled backhoe or excavator vehicle in which the hitch includes a body having a pair of upstanding side walls for hinge mounting onto the manipulative end of the boom. At the underside of the body secured in a relatively forward location of a bottom wall connecting the sidewalls is a hook member defining a transverse jaw channel in which to receive a transverse hingepin extending between spaced apart support lugs secured to the backside of the bucket. Rearwardly extending downward from the backside of the bottom wall is an elongated transverse sleeve adapted to be received intervening between the lugs of the bucket and containing a cyindrical rotatably displaceable bushing within the bore of the sleeve. The bushing is formed having an eccentric internal bore that by arcuate displacement of the bushing can be axially aligned with opposite apertures in the lugs. A support pin extending through the lugs and bushing secures the hitch apparatus attached to the bucket and can be withdrawn for subsequent detachment.
