Claims
- 1. Apparatus for remote handling of equipment, comprising:a fixed jaw and a mobile jaw; actuating means for linearly displacing the mobile jaw relative to the fixed jaw; said actuating means comprising a first arm integral with a first handle, and a second arm integral with a second handle; said handles being articulated on a same articulation axis; each arm having a free end; a cable having two ends and coupling said actuating means to said equipment; a first end of said cable being connected to the mobile jaw, said cable sliding inside a flexible sheath having a first end and an opposite second end; the first end of the sheath abutting the fixed jaw, and the free end of said first arm structured and arranged to serve as a stop for the second end of the sheath, while allowing the cable passing therethrough to slide freely; the free end of said second arm being connected to a second end of said cable; a ratchet mechanism mounted on one of the handles cooperating with a stub provided on the other handle for holding said handles one against the other and therefore keeping the mobile jaw in a position close to the fixed jaw, except when the stub of the ratchet is released by the action of an unlocking mechanism; and wherein the first arm and the first handle are aligned parallel to a median axis passing through the articulation axis between the handles, and the second arm and second handle form between them, an angle in a plane of movement perpendicular to the articulation axis of a size such that when the two handles are brought towards one another, the distance between the free ends of the two arms is at least equal to the maximum linear displacement of the mobile jaw.
- 2. The apparatus according to claim 1, wherein each arm and its respective handle is formed as a strip substantially leaving supports for the handles and the articulation flat, while the arms are twisted 90° on themselves to receive respectively at their free ends machining forming the stop for the sheath for the first arm, and the cable connection for the second arm.
- 3. The apparatus according to claim 1, further comprising a return spring arranged between the two handles close to their articulation, said spring urging said handles and hence the mobile jaw and the fixed jaw apart when at rest.
- 4. Apparatus for remote handling of equipment, comprising:a fixed jaw and a mobile jaw; actuating means for linearly displacing the mobile jaw relative to the fixed jaw; said actuating means comprising a first arm integral with a first handle, and a second arm integral with a second handle; said handles being articulated on a same articulation axis; each arm having a free end; a cable having two ends and coupling said actuating means to said equipment; a first end of said cable being connected to the mobile jaw, said cable sliding inside a flexible sheath having a first end and an opposite second end; the first end of the sheath abutting the fixed jaw, and the free end of said first arm structured and arranged to serve as a stop for the second end of the sheath, while allowing the cable passing therethrough to slide freely; the free end of said second arm being connected to a second end of said cable; a ratchet mechanism mounted on one of the handles cooperating with a stub provided on the other handle for holding said handles one against the other and therefore keeping the mobile jaw in a position close to the fixed jaw, except when the stub of the ratchet is released by the action of an unlocking mechanism; wherein the two handles are brought towards one another, in a plane of movement perpendicular to the articulation axis, the arms move apart in the same plane, symmetrically one to the other in relation to a median axis passing through the articulation axis and between the handles to make an angle such that when the two handles are one against the other, the distance between the free ends of the two arms is at least equal to the maximum linear displacement of the mobile jaw.
- 5. The apparatus according to claim 4, wherein each arm and its respective handle is formed as a strip substantially leaving supports for the handles and the articulation flat, while the arms are twisted 90° on themselves to receive respectively at their free ends machining forming the stop for the sheath for the first arm, and the cable connection for the second arm.
- 6. The apparatus according to claim 4, further comprising a return spring arranged between the two handles close to their articulation, said spring urging said handles and hence the mobile jaw and the fixed jaw apart when at rest.
- 7. Apparatus for remote handling of equipment, comprising:a fixed jaw and a mobile jaw; actuating means for linearly displacing the mobile jaw relative to the fixed jaw; said actuating means comprising a first arm integral with a first handle, and a second arm integral with a second handle; said handles being articulated on a same articulation axis; each arm having a free end; a cable having two ends and coupling said actuating means to said equipment; a first end of said cable being connected to the mobile jaw, said cable sliding inside a flexible sheath having a first end and an opposite second end; the first end of the sheath abutting the fixed jaw, and the free end of said first arm structured and arranged to serve as a stop for the second end of the sheath, while allowing the cable passing therethrough to slide freely; the free end of said second arm being connected to a second end of said cable; a ratchet mechanism mounted on one of the handles cooperating with a stub provided on the other handle for holding said handles one against the other and therefore keeping the mobile jaw in a position close to the fixed jaw, except when the stub of the ratchet is released by the action of an unlocking mechanism; wherein the two handles are brought towards one another in a plane of movement perpendicular to the articulation axis, the arms to which they are respectively connected are angled in the same plane, on the same side of a median axis passing through the articulation axis and between the handles, the second arm being angled more than the first arm, such that when the two handles are one against the other, the distance between the free ends of the two arms is at least equal to the maximum linear displacement of the mobile jaw.
- 8. The apparatus according to claim 7, wherein each arm and its respective handle is formed as a strip substantially leaving supports for the handles and the articulation flat, while the arms are twisted 90° on themselves to receive respectively at their free ends machining forming the stop for the sheath for the first arm, and the cable connection for the second arm.
- 9. The apparatus according to claim 7, further comprising a return spring arranged between the two handles close to their articulation, said spring urging said handles and hence the mobile jaw and the fixed jaw apart when at rest.
- 10. The apparatus according to claim 7, wherein the area of articulation of the second arm does not coincide with the area where said second arm joins the second handle, which is offset by an appendage that unites the two areas.
