Definitions

  • the present invention relates to hooks comprising a safety latch which is pivotally mounted on the body of the hook so as to be able to be applied to the spout of this hook and to close the opening thereof, and the end portion of which opposite the spout possibly has a connecting element, for example an eye.
  • the latch thus automatically comes into the safety position when the hook is subjected to a load.
  • hooks of this kind comprising a latch which is disposed at the rear of the hook and of which a spout can engage in an opening provided in the central part of the latch, when the latter is in the safety position.
  • the latch cannot thus inadvertently release the opening of the hook. But experience shows that it can happen that the latch, by pivoting from its safety position, comes to jam the thumb placed on the lock.
  • the present invention relates to an improvement made to these hooks in order to avoid this drawback.
  • the hook according to the invention is characterized in that the latch comprises, at its rear part, a boss capable of coming into abutment against a substantially tangent face of the lock, which limits the pivoting of the latch, and in that the hook body is shaped so as to allow the latch to pivot by a sufficient angle so that its beak emerges from the opening of the latch in the safety position, but insufficient for it come outside the path of the boss of this latch.
  • the central part of the pawl has a second opening in which the spout of the latch can engage when the boss of the pawl bears against this latch.
  • the safety latch 4 is pivotally mounted around an axis 5 between two ears the provided at the upper part of the body 1.
  • the upper end of this latch is provided with an eye 6 and its lower end can be applied to the spout 3 by closing the opening 2 and thus preventing the release of the sling or the ring in which the spout 3 has been engaged.
  • the lock 7 is pivotally mounted at 8 at the rear of the body 3, between the two ears la.
  • the bolt or beak 9 of this lock can engage in an opening 10 of complementary shape provided at the periphery of the central part 4a, forming a hub, of the latch 4 so immobilizing the latter in its safety position; a certain play is of course provided to allow the spout 9 of the lock to disengage from the opening 10.
  • a machining 11 provided in the body 1 allows the lock 7 to pivot enough so that its beak 9 emerges from the opening 10.
  • the hub 4a of the length 4 has a second opening 12 in which the spout 9 of the lock can engage when the latch is in the open position ( Figure 2).
  • This opening also has a shape complementary to that of the spout 9, that is to say it has two faces 12a and 12b against which the faces 9a and 9b of this spout 9 come to bear.
  • the latch has a boss 4b which comes to bear on the face 9c of the spout 9, opposite the face 9a thereof.
  • This face 9c is substantially tangent, that is to say perpendicular to the radius of rotation of the latch 7, passing through the point of contact.
  • the machining 11 has a depth allowing the latch 7 to pivot sufficiently so that the thumb 13 of the user operating the latch is not crushed by the latch coming in the open position. However, this depth is insufficient to allow the face 9c of the spout 9 to come out of the path of the boss 4b.
