Definitions

  • the present invention relates to a drive device with large travel, automatic approach and large multiplication of force applicable to pliers, scissors and most tools consisting of two handles and which must be closed manually as tongs, riveters or shears.
  • the tool incorporating this device, automatically adapts to the size of the piece without the need for any previous manipulation.
  • an important feature is that every time the handles are closed and opened the blades are closed a small amount until the total closure is completed. In addition to avoiding the need to use other tools with very long handles, this system is handled with the speed and agility of traditional scissors until contact with the piece is established.
  • the tool using the drive system according to the present invention patent, comprises a first member composed of the jaw, or specific piece of the tool, followed by an intermediate piece, where the main shaft is located, and the handle.
  • the second member consists of the jaw, or specific piece of the tool, and the intermediate part that is articulated in its central area with the first member or is moved by a slide with respect to the first member.
  • the third member is the handle of the second member described above and articulates with it at the opposite end to the specific jaw or piece of the tool.
  • This joint in addition to being a joint, consists of a prestressed spring and a stop that prevents this spring from rotating the handle indefinitely with respect to the second member.
  • the action of the joint, spring and stop make these two members behave as if they were a single kinematic link, similar to member one, as long as there is no force that modifies the length of the spring. In this situation, the system behaves like a conventional tool with a large path in the jaws or specific parts of the tool.
  • the handles continue to close, the spring that joins the handle and the second member yields and a rotation occurs between them.
  • the handle will stop touching the stop and the ratchet, also separating from its stop, will be released and will move forward until it touches the integral teeth of the first member.
  • the system becomes a new mechanism consisting of a new lever constituted by the handle that is divided into two very unequal parts: one is practically its length and the other the distance between the axis that joins it with the second member and ratchet shaft. Being the disproportion of these distances very large the force that is achieved in the jaws is considerable.
  • a second ratchet can optionally be mounted so that the angle of closure gained does not recede when opening the handles. In this way it is achieved, opening and closing the handles successively, so that the blades are progressively closed from the initial position until the piece is pressed or cut.
  • Another optional accessory is a toothed arm that is articulated at the end of one of the handles and can be deployed and attached to an elastic hook attached to the other handle. In this way a piece can be kept pressed without operator manipulation.
  • This tool can be combined with articulated levers that can serve as an extension of the handles if you need a large lever arm.
  • Figs. 1 to 3 represent part of the number one, two and three members.
  • Fig. 4 represents the assembly formed by members two and three joined together. In this Fig. Two stops are observed, (12) and (13), integral to the member 2 that limit the rotation produced by a spring (14).
  • Fig. 5 shows the deformation of the previous assembly when external forces are applied.
  • Fig. 6 shows a ratchet (16) articulated to member 3.
  • Fig. 7 shows the assembly formed by the previous pieces.
  • Figs. 8 and 9 show in detail the situation when no effort is being made on the tool.
  • the member 3 touches the foraia stop (13) that the assembly formed by the member 2 and 3 behave like a single kinematic link without relative movement with each other as shown in Fig. 4.
  • the ratchet (16 ) is turned towards link 3 by making contact with the stop (13).
  • Figs. 10 and 11 show the rapid approach to the work piece.
  • Fig. 12 it is shown how, as the handles continue to join together, the assembly formed by members 2 and 3 begins to fold, which allows the spring (18) of the ratchet to act causing it to meet the teeth. This process ends in the position corresponding to Fig. 13.
  • Fig. 15 There is a second ratchet (20) articulated to link 2 whose purpose is to prevent the jaws or blades from receding, Fig. 16 and 17, if the tool handles are separated again.
  • Fig. 18 shows how the toothed retaining part (19) engages in the part (22) and locks the tool.
  • Fig. 19 shows the fully assembled tool.
  • Figs. 20 and 21 show another embodiment of the tool, based on the same principles, where the joint (8) between members 2 and 3 has been replaced by a slide joint. (108)
  • the present invention consists of a drive device for tools consisting of two handles which, used for pliers as a non-limiting example, is essentially composed of the members whose parts are shown in Figs. 1, 2 and 3.
  • Fig. 1 represents part of the member 1 which is formed by the first jaw, intermediate part and handle and has the toothed part (6) attached.
  • the ratchet (16) will act on these teeth.
  • Fig. 2 represents part of member 2, formed by the second jaw and the intermediate part.
  • the shaft (8) that is coupled with the hole (5) mentioned above.
  • Fig. 3 represents part of member number 3 that constitutes the lower handle of the tool and is articulated with member 2 thanks to its bore (11).
  • the projections (10) and (9) will serve to limit the angle of rotation by being able to contact the stops (12) and (13).
  • Fig. (4) represents the assembly formed by members two and three joined by the joint (15). In this Fig. Two stops are observed, (12) and (13), integral to member 2.
  • the stop (13) limits the rotation produced by a prestressed spring (14) that forces, in the absence of other forces, link 3 make contact with the stop (13).
  • Fig. (5) shows how the assembly shown in Fig. (4) is modified when external forces are applied.
  • Fig. (6) shows a ratchet (16) articulated on an axis (17) close to the axis (15). On this acts a spring (18) that tends to rotate it by pulling it towards the outside of the handle.
  • Fig. 7 shows the assembly formed by the pieces described above.
  • Figs. 8 and 9 show in detail the situation when no effort is being made on the tool, this happens as long as the two jaws or blades do not press the work piece together.
  • the member 3 touches the stop (13) so that the assembly formed by the member 2 and 3 behaves like a single kinematic link without relative movement with each other.
  • the ratchet (16) is forced to enter the link 3 because its upper corner makes contact with the stop (13).
  • Its possible action with the teeth belonging to (6) and integral to link 1 is annulled in this situation: these circumstances mean that in this first phase of operation the assembly behaves like a conventional tool with a relatively large jaw path, which It allows a quick approach to the work piece. This is illustrated in Figs. 10 and 11 that show this approximation.
  • a second ratchet (20) is observed articulated with link 2.
  • the ratchet is in its resting position, which is achieved because its U-shaped spring (21) tends to open and thanks at the alignment of the ends of the spring and the ratchet joint acts a pair clockwise.
  • Fig. 18 shows how the toothed retaining part (19) that is usually retracted acts, a situation shown in Fig. 15, to engage in the piece (22) and thus allow one or more pieces to be held without need for operator manipulation.
  • the piece (22) is attached to the member 3 by one end in such a way that it can be flexed enough to fit the teeth (22).

Abstract

L'invention concerne un procédé consistant à incorporer une pièce dentée solidaire dans un des manches et à diviser l'autre au moyen d'une articulation, maintenant dans la phase d'approche de l'outil sa rigidité à l'aide d'un ressort pré-tendu et d'une butée, et permettant ensuite une déformation faisant intervenir un cliquet et modifiant le mécanisme, un second système de levier étant alors utilisé, permettant de transmettre une force élevée. Le dispositif de l'invention comprend des cliquets supplémentaires permettant des approches successives et le blocage de l'outil. On obtient une approche rapide et automatique, s'adaptant à la pièce sans manipulation préalable, et exerçant une force jusqu'à vingt fois supérieure à celle appliquée dans les manches. L'outil conserve la même agilité et capacité de fonctionnement que l'outil original, exigeant une pression très réduite de la part de l'utilisateur.
