Definitions

  • the invention relates to a pair of pliers for collecting objects or slugs, consisting of two symmetrical clamp halves which are pivotable relative to each other.

  • this guide pin is screwed in the first half bracket so that it is adjustable, can be stabilized either deeper or less deep in the first half bracket. This has the consequence that the coil spring, through which the guide pin is inserted, the lower half of the second half of the clamp applied with less force with less deep screwing with less force.
  • concave recesses are provided which can take nudibles with closed forceps. Gripping pins that point diagonally in the direction of the actuating lever and are rounded at the tips, additionally guarantee a safe intake of nudibranches and prevent at the same time that they can catch on the gripper ends.
  • the hooks are present at the ends, but a) to Spitz (injury of slugs, increased mucus secretion), b) much too massive (no complete closing of the gripper ends is possible).
  • the gripping ends can be completely closed because the gripping pins in the concave recesses leave enough room for it, so that the slugs are included in the concave recesses at the tips and are additionally held by the rounded gripping pin.
  • shaking off the wrench is squeezed to the operating levers (handles) and beaten with the gripper ends lightly on the edge of a designated vessel, which causes the safe removal of the worm from the pliers.

  • nude scraps can catch in the catch elements after gripping, removal could be impossible by shaking alone.
  • the catch elements are simplified, so they do not guarantee a secure hold, as snails get caught in contact with the pliers and can slide upwards and slide off.

Compare the concave recesses on the gripping ends with the gripping pins in my invention. Andre's pliers, of all the above, would be most suitable for the activity of nudibranch picking, but are incomparable in construction to my invention, because the design requires much more operations and parts (more expensive to manufacture).

Abstract

L'invention concerne une pince servant à ramasser des objets ou des limaces, cette pince étant constituée de deux branches symétriques (1, 2) pouvant pivoter l'une par rapport à l'autre. Chaque branche présente un levier d'actionnement et un levier de préhension. L'extrémité de préhension présente des évidements concaves dans lesquels est placée une pointe de préhension (8). Les pointes de préhension présentent une forme de cône à bout arrondi et sont inclinées en direction du levier d'actionnement. Entre les branches est disposé un ressort de torsion (4) qui forme l'articulation des branches pouvant pivoter à la manière d'une pince. Les extrémités coudées du ressort de torsion sont fixées (10) chacune à une branche et soumettent la pince à une précontrainte en position fermée. Dans un trou (13, 14) traversant les deux branches, une goupille de guidage (6) est fixée de façon réglable (14) dans la première branche, passe à travers la seconde branche avec du jeu (13) et est guidée à travers un ressort hélicoïdal (5) qui sollicite les branches en position fermée. La force de sollicitation peut être régulée (6c). Pour la production d'une pince selon l'invention dans différentes longueurs, les proportions A : B : C = 5 : 3,5 : 1 sont appropriées.
