Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

The present invention has been described according to preferred embodiments, but equivalent variants can be conceived without departing from the protective scope offered by the following claims.

CLAIMS

1. Crushing tool (1), suitable for being fixed to a movable arm of an operating machinery or another similar device, comprising

a support (2) fixable to the free end of the movable arm,

a first jaw (5) connected to said support (2),

a second jaw (6) articulated to said first jaw (5) at a first articulation axis (A), said first jaw (5) and second jaw (6) comprising respective distal portions (7) and proximal portions (8), provided with respective distal operating ends (7a) and proximal operating ends (8b), suitable to operate on materials of different types and/or with different features in order to obtain the crushing or breaking thereof, and

at least one linear actuator (13; 13a, 13b), having a first end (14) articulated to said support (2) at a second articulation axis (B), and a second end (15) articulated to said second jaw (6) at a third articulation axis (C),

characterized in that it comprises variation means (18) of the position of said second articulation axis (B) and/or of said third articulation axis (C) with respect to the position of said first articulation axis (A), so as to obtain different use configurations of the tool (1).

2. Tool according to claim 1, wherein said variation means (18) are suitable to modify the position of said second articulation axis (B) with respect to the position of said first articulation axis (A), and comprise an articulation pin (19), integral with said first end (14), and at least two seats (20,21), provided in said support (2), for the selective engagement of said articulation pin (19), so as to obtain at least two corresponding different use configurations of the tool (1), in particular at least one first configuration and at least one second configuration.

3. Tool according to claim 2, wherein said seats (20,21), comprising a first

seat (20) and a second seat (21), are substantially aligned along the longitudinal axis of the tool (1), or of said support (2).

4. Tool according to one of claims 2,3, wherein said seats (20,21) comprise respective through holes provided in said support (2).

5. Tool according to claim 4, wherein said seats (20,21) comprise respective pairs of through holes, coaxial and opposite, provided in the opposite walls (23) of said support (2).

6. Tool according to one of claims 2-5, wherein said first ends (14) of said linear actuator (13) comprises a kind of eyelet, within which said articulation pin (19) is engaged.

7. Tool according to claim 6, wherein said articulation pin (19) comprises two opposite terminal portions (24) which project with respect to said first end (14), so as to be engaged in said seats (20,21) of said support (2).

8. Tool according to the preceding claim, wherein said variation means (18) comprise means for selective insertion/removal of said opposite terminal portions

(24) of said articulation pin (19) in said seats (20,21).

9. Tool according to claim 8, wherein said selective insertion/removal means are manual or automated.

10. Tool according to the preceding claim, wherein said selective insertion/removal means comprise a device suitable to selectively retract said opposite terminal portions (24) of said articulation pin (19), in a manner so as to allow the removal of such portions from said seats (20,21).

11. Tool according to one of the preceding claims, wherein said distal operating ends (7a) are shaped in such a way to make an opening angle greater than that of said proximal operating ends (8a).

12. Tool according to the preceding claim, wherein said proximal operating ends (8a) are suitable to operate as shears.

13. Tool according to one of the claims 2-12, wherein the first center distance (Dl) between said first articulation axis (A) and said second articulation axis (B) in said first use configuration is smaller than the second center distance (D2) between said first articulation axis (A) and said second articulation axis (B) in said second use configuration.

14. Tool according to one of the claims 2-13, wherein the second maximum value (F4) of the force exerted by said jaws (5,6) obtainable in said second use configuration, given the same linear actuator (13) used, is greater than the first maximum value (Fl) obtainable in said first use configuration.

15. Tool according to claim 1, wherein said variation means (18) are suitable to modify the position of said second articulation axis (B) with respect to the position of said first articulation axis (A), and comprise a seat integral with said first end (14), and at least two articulation pins, integral with said support (2), for the selective engagement within said seat.

16. Tool according to one of the preceding claims, wherein said first jaw (5) and said second jaw (6) are both rotatable around said first articulation axis (A), said tool (1) comprising a first linear actuator (13a) and a second linear actuator (13b) respectively associated with said first jaw (5) and with said second jaw (6), so as to obtain a mirrored configuration with respect to the longitudinal axis of the tool (1).
