Definitions
- TITLE Safety device for quick coupler intended to fix a tool at the end of the arm of a loader or the like.
- the present invention relates to a safety device for quick coupler intended to fix a tool at the end of the arm of a loader or the like.
- a fastener in two parts, comprising a hooking member provided with a cradle making it possible to straddle a shaft made integral with the other part, one of the parts comprising an opening that can be crossed by a hook-shaped extension under which a sliding locking plate can be inserted, making it possible to keep the two parts constituting the fastener pressed against one another.
- the locking plate is kept in the armed position and, in this position, it does not oppose the passage of the hook-shaped extension through the aforementioned opening. It is during this passage that the aforementioned extension releases the locking plate which, under the action of springs which relax, is inserted under the hook to lock the two parts of the fastener one against the other.
- the hook and the plate have oblique surfaces which cooperate and press the two parts of the fastener one against the other. If, for any reason, presence of earth for example, the locking plate extends only imperfectly under the corresponding part of the hook, the abovementioned cooperation is imperfect and under shock and vibration, there is a risk of stalling fear with all the inconvenience this may present.
- the present invention which overcomes this drawback, is remarkable in that the hook has a means capable of cooperating with the locking plate to oppose the rotation of the part of the fastener comprising said hook.
- FIG. 1 is a view of a quick coupler of a known type
- FIG. 2 is a view, on a larger scale of FIG. 1, showing the position of the locking plate when an incident occurs;
- FIG. 3 is a view, similar to that 1, showing a modified fastener according to the invention
- FIG. 4 is the top view of FIG. 3;
- FIG. 5 is a view, similar to that 4, showing the fastener in the safety position
- FIG. 6 is the elevation view of FIG. 5
- the fastener which conforms to that described in the French patent application published under the number 2785952, has two parts 1 and 2, each substantially affecting the shape of a stirrup.
- One of the parts has a shaft 3 which can be gripped by a cradle 4 of the other part.
- the part 2 has on its middle part 2a an extension 5 forming
- the extension 5 can pass through an opening 7 provided on the middle part 1 a of part 1.
- On the part 1 can slide a locking plate 8, having an opening 9 for passage of the extension 5.
- the plate 8 is shown in the armed position, the openings 7 and 9 being substantially coincident.
- the plate 8 is held in this position by means, for example of a pivoting locking finger 10.
- the oblique edge 8a of the plate 8 is inserted under the part 6a of the hook, the cooperation of the oblique parts in contact having the effect of pressing two parts of tie it together.
- the present invention which overcomes this drawback, consists in providing a safety device opposing the pivoting of the part comprising the hook as soon as the latter has passed through the openings 7 and 9.
- the extension 5 has at its upper part, at least, a lateral finger 11, the openings 7 and 9 having recesses 12 and 13 allowing the passage of said finger.
- the extension 5 repels the finger 10 and the fingers 11 are located above the plane of the plate 8, which moves according to the arrow Fi.
- FIG. 6 is shown the same type of incident as that represented in FIG. 2: the contact between the surfaces 6a and 8a is very imperfect from the ground preventing, for example, the plate 8 from fitting completely under the hook. If the contact between the two aforementioned surfaces is broken, part 2 of the fastener will pivot, slightly until the fingers 11 will come to bear against the plate 8 by opposing the stall and the fall of the tool linked to said part 2.
