Fork lift attachment for multi-purpose bucket
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.
1. A fork attachment for use with a multi-purpose bucket to convert the bucket into a forklift, said bucket having at least two jaws pivotally mounted to each other with at least one of the jaws having a leading edge, said fork attachment comprising:
(a) a fork tine having a forward part, a rear part and a top side;
(b) at least one member forming a rear facing slot adjacent the top side of said tine to engage the leading edge of the one jaw of said bucket therein, and
(c) a pivoting latch secured in the jaw of the bucket and attached to the tine to resist movement of the tine relative to the one jaw of said bucket away from engagement of said leading edge in said slot.
2. The fork attachment of claim 1 wherein the latch is removably attached adjacent the slot forming member.
3. The fork attachment of claim 1 wherein the latch is removably attached to said tine.
4. The fork attachment of claim 1 wherein the latch is positioned on the top side of the tine.
5. The fork attachment of claim 4 wherein the one jaw has a rear edge and the latch is positioned to engage the rear edge of the one jaw of said bucket.
6. The fork attachment of claim 5 wherein the latch is hinged to allow the latch to move to engage the rear edge of the one jaw of said bucket.
7. The fork attachment of claim 1 wherein the latch is positioned to be clamped between the two jaws of the bucket.
8. The fork attachment of claim 1 wherein the latch is rotatably mounted to the tine and has a rear surface with a rear contact point and a front surface with a front contact point and wherein the force of the second jaw of the bucket against the rear surface of the latch causes the front contact point of the latch to engage the one jaw of the bucket.
9. The fork attachment of claim 8 wherein the latch is rotatably mounted to the tine by a hinge and the rear contact point is farther from the binge than the front contact point.
10. The fork attachment of claim 1 wherein the tine has a hinge attached to its rear part and wherein the latch has a rear contact point and the latch is attached to the slot forming member by a link extending therebetween, and the attachment point of the link to the latch is at a location farther from the hinge than the rear contact point of the latch is from the hinge.
11. The fork attachment of claim 10 wherein the link is adjustable.
12. The fork attachment of claim 1 , wherein the latch has a front side facing the tine, and a back side, and wherein the latch has a safety stop on the front side of the latch.
13. The fork attachment of claim 1 wherein the tine has at least two hinge points on its rear part and wherein the latch is selectively attachable to the tine at at least the two locations of the hinge points.
14. The fork attachment of claim 1 further including a rear bearing point on the top side of the tine for engagement with the one jaw of said bucket.
15. The fork attachment of claim 1 further including a front bearing point on the slot forming member for engagement with the one jaw of said bucket.
16. The fork attachment of claim 1 further including a vertical extension extending upward from adjacent the slot forming member and not attached to said bucket, whereby the vertical extension acts as a backstop to stabilize a load carded on the tine or tines, and as a visual aid to the operator of the bucket to help determine the location of the tine when picking up a load.
17. The fork attachment of claim 16 wherein the vertical extension further includes a lifting aid.
