Definitions
- TITLE Quick coupler to attach a tool to the end of the arm of a loader or the like
- the present invention relates to a quick coupler for fixing a tool to the end of the arm of a loader or the like.
- a quick coupler has two parts, one of which is made integral with the arm of the machine and the other resulting from a modification of the tool or is constituted by a part made integral with said tool.
- One of the parts comprises a shaft, situated towards one of the ends of said part, capable of cooperating with a hook, forming an open bearing, carried by the other part.
- This device gives full satisfaction when applied to the fixing of small-sized buckets, but it is no longer the same when it comes to large-sized buckets because the forces which come into play are incompatible with the use of silent blocks.
- one of the parts of the fastener comprises a movable wedging member capable, at the end of the locking of the two parts, of being inserted between them, the contact taking place at a point situated substantially in line with the tree.
- FIG 1 is a sectional view of the part of the fastener, comprising the shaft, modified according to the invention
- FIG 2 is the top view of Figure 1;
- FIG. 3 is a sectional view of the part of the fastener comprising the hooks, modified according to the invention.
- FIG. 4 is the top view of FIG. 3;
- FIG. 5 is a sectional view, at the end of locking and showing the action of the device of the invention;
- FIG 6 is a sectional view, similar to that 5, showing the position of the movable members allowing the stall.
- the attachment shown has been limited, so as not to unnecessarily complicate the drawings, to the organs necessary for understanding the device of the invention. It should therefore be noted that all the components necessary to fix one or other of the parts either on the bucket or on the loader arm have been omitted.
- the attachment consists of two parts 1 and 2, that 1 comprising the shaft 3 and that 2 the hooks 4.
- the locking is effected by means of an automatic snap-in operation involving a sliding plate 5 carried by the part 1 and the notch 6 of a shoe 7 carried by the part 2.
- This mechanism is described in prior documents and , in particular, in document FR-2785952.
- the part 2 comprising the hooks, has an extension 8 extending substantially in line with the location of the axis of the shaft 3, said extension forming between it and the corresponding face la of part 1, when the two parts are locked, a space in which a wedging member 9 can be inserted.
- the extension 8 has an oblique surface 8a, forming a ramp, capable of cooperating with a similar surface 9a of the member 9 when the latter moves along the arrow F1.
- the member 9 is carried by a sliding plate 10 , held against the face 1a of the part 1.
- the plate 10 is constantly subjected to a force tending to move it according to the arrow Fl. Springs, not shown
- Maintaining and guiding the plate 10 is ensured by known means, similar to those used for maintaining and guiding the plate Locking 5.
- the plate 10 is subjected to the action of springs (not shown) similar to those, known, used for the plate 5.
- the recoil of the plate 5 is used to determine that of the plate 10, the two plates being judiciously dimensioned so that the stroke of the plate 5 is greater than that of the plate 10 .
- the plate 10 has at least one finger 1 1 passing through the usual orifice
- the plate 5 is displaced, according to arrow F2, in the usual way.
- the recoil of the plate 5 determines that of the plate 10 by means of the fingers 1 1 entrained by the edge 13a of the orifice 13.
- the part 2 can then pivot freely according to the arrow F3.
