Definitions

  • This invention relates to a jaw tool as disclosed in the preamble of claim 1.
  • Pliers, pincers or cutting nippers, with an electrically insulating safety device preventing any unintentional approaching of an operator's hands to the metal portions of the jaws are known (US-A-1 503 536).
  • Still today pliers for operating under tensioning are used, having on the pliers' handles or handgrips a coating of suitable insulating material, and having on said handles adjacent to the jaws such bulges that an operator, when holding the pliers in his hand, cannot exceed with his fingers said bulges, and accordingly come unintentionally into contact or touch with the metal portion which, when the pliers operate on a circuit under tension, may give rise to fatal accidents.
  • a drawback is that when electrically insulated pliers have the capability of a considerable opening, adjacent to the jaw pivoting point there is a quite wide opening that a finger may slip therebetween and thus come into contact or touch with the metal portion.
  • This invention is directed to overcome such a drawback of a known electrically insulated jaw tool in a simple and effective manner.
  • the invention proposes a jaw tool of the type having known enlarged portions on the handles adjacent to the jaws for preventing an operator's hand from exceeding from the outside such enlarged portions.
  • segments are provided between such enlarged portions, said segments at least partly sliding in an opening of such an enlarged portion, for making up an obstacle to any unintentional touch of an operator's hand or fingers to the metal between the tool handles beyond such segments.
  • the pliers shown therein comprise handles 1 and 2, which are covered with a suitable insulating material and extending at the top in jaws 3 and 4 pivoted to each other at 5.
  • pliers of this type comprise enlarged portions 6 and 7 provided on the handles adjacent to the pivoting point, having the purpose that an operator's hand gripping said handles 1 and 2 is inhibited from exceeding the enlarged portions 6 and 7, unintentionally reaching into the zone of said jaws 3 and 4, the latter being not insulated.
  • openings respectively indicated at 10 and 11 are provided in said enlarged portions 6 and 7, preferably on either side of the pliers, in which openings a segment 12 of any suitable material is slipped in.
  • Such openings 10 and 11 and accordingly said segment 12 may be configurated as an arc of circle with center at 5, or said openings may be simply straight or rectilinear and said segment 12 may have a sufficient degree of flexibility to be arranged as an arc of circle in the free section and straight or rectilinear in the section inside said openings 10 and 11.
  • the segment 12 may be blocked on one enlarged portion, for example enlarged portion 10, and freely slidable in enlarged portion 11, or may be freely slidable in both, being of a sufficient length that at maximum opening of the pliers it cannot exit from said openings 10 and 11.

Claims (6)

1. Ein Maulwerkzeug mit Griffen (1, 2), die mit elektrisch isolierendem Material überzogen sind, mit in der Nähe des Mauls (3, 4) als Schutzausbauchungen vorgesehenen erweiterten Bereichen (6, 7), um das Überschreiten der erweiterten Bereiche (6, 7) mit der Hand des Bedieners zu verhindern, dadurch gekennzeichnet, daß zwischen dem erweiterten Bereich (6 oder 7) des einen Griffes und dem erweiterten Bereich (6 oder 7) des anderen Griffes ein zusätzliches Hindernissegment (12) vorgesehen ist, daß die Hand des Bedieners daran hindert, das Segment (12) zwischen den geöffneten Werkzeuggriffen (1, 2) zu überschreiten, das Segment (12) ist gleitend (Fig. 3) zumindest teilweise in einer Öffnung (11) eines erweiterten Bereiches (7) vorgesehen.
2. Ein Werkzeug nach Anspruch 1, dadurch gekennzeichnet, daß das Segment (12) an einem erweiterten Bereich (6 oder 7) an einem Griff (1 oder 2) gesichert ist und in der Öffnung (11 oder 10) des erweiterten Bereiches (7 oder 6) an dem anderen Griff (2 oder 1) frei gleitbar ist.
3. Ein Werkzeug nach Anspruch 1, dadurch gekennzeichnet, daß das Segment (12) in Öffnungen (10 und 11) der erweiterten Bereiche (6, 7) beider Griffe (1 und 2) frei gleitbar ist.
