Definitions

  • the present invention refers to an improved hand tool of the gripper-type used to secure one or several objects and that due to its special structure and shape has some advantageously minimum dimensions.
  • the tool of the invention is of the type that consists of a fixed arm member and another moveable arm member, as well as a fixed clamp member and another moveable clamp member in order to secure objects securely and totally correctly.
  • the tool includes a locking mechanism in order to ensure the blocking position.
  • the novelty of the invention is centered essentially on this effective and simple blocking mechanism that has an advantageous structure and functioning.
  • Said clamp comprises an L-shaped frame, an internally screw threaded sleeve at the end of one leg of the frame, said sleeve lying along an axis parallel with the other leg of the frame, a handle on the frame lying in alignment with the second mentioned leg of the frame, a spindle mounted in the sleeve for longitudinal adjustment therethrough, a clamp pad at the end of the spindle remote from the handle, a L-shaped movable jaw pivoted to the end of the second mentioned leg of the frame to exert a clamping force against the end of the spindle, a clamp pad on the movable jaw adapted when the clamp is in work holding position to align with the pad on the spindle, a handle pivoted to the movable jaw in spaced relation to its pivoted connection with the frame, a link pivoted to the handle near its pivoted connection with the movable jaw and a pivot connecting
  • the improved hand tool as claimed that constitutes the object of the invention is of the gripper-type for securing objects, which at the same time due to its special shape has reduced dimensions.
  • It comprises two arm members, a fixed one and another moveable one, the same having a fixed clamp member and a moveable clamp member, respectively, both being face to face and between which one or several objects to be secured will be placed.
  • the object or objects will be pressed between both clamp members when the tool assembly is in its active blocking or locking position.
  • the tool includes a locking mechanism that is defined by a connecting rod that is jointedly coupled by one of its ends to a cylinder where the moveable clamp member itself is connected and which is conveyed in a guiding slot of the fixed arm member.
  • the other end of the connecting rod is connected, also jointedly, to the moveable arm member itself, that is in turn jointedly connected to an end point of the fixed arm member.
  • the improved hand tool comprises a fixed arm member (1) and another moveable arm member (2), both including a fixed clamp member (3) and a moveable clamp member (4), respectively.
  • the fixed arm member (1) constitutes the main body of the tool.
  • the tool of the invention includes a blocking or locking mechanism in order to ensure the securing by pressure of one or several objects (5) located between both clamp members (3) and (4).
  • This blocking or locking mechanism is defined by a connecting rod (6) that is jointedly coupled by an end point (7) in a piston (8) that is conveyed in a guiding slot (9) of the fixed arm member (1).
  • the other end of the connecting rod (6) is jointedly coupled in an intermediate point (10) of the moveable arm member (2), both arm members (1) and (2) also jointedly connecting in an end point (11).
  • the moveable arm member (2) is connected to a cylinder (12) integral with the piston (8) and wherein the moveable clamp member (4) screws.
  • the moveable arm member (2) also includes a cam-type lever (13) that is jointed in a top articulation (14) of said moveable arm member (2), the purpose of said lever (13) being to facilitate the unlocking or unblocking of the moveable arm member (2) and in general of the tool assembly of the invention.
  • the fixed clamp member (3) although it forms an integral part of the fixed arm member (1) like an elbowed extension thereof, said fixed clamp member (3) could be defined by a detachable-type independent element secured to the cited fixed arm member (1).
  • the two clamp members (3) and (4) are face-to-face, in such a way that in order to place the tool in an active blocking position, it will be necessary to tilt the moveable arm member (2) until the same abuts against the fixed arm member (1), in such a way that in this process, the piston (8) will move conveyed in the guiding slot (9) of the fixed arm member (1), the moveable clamp member (4) approaching the fixed clamp member (3), between which the objects to be secured (5) (figure 1) are located.
  • the two articulation points (7) and (10) of the connecting rod (6) and also the articulation point (11) that connects both arm members (1) and (2) are advantageously aligned in the same direction.
  • the spring (15) In the blocking position of the tool, the spring (15) is compressed, in such a way that in the unblocking operation, the spring will assist in said operation.
  • the distance between the two clamp members (3) and (4) may be advantageously adjusted, depending on the needs thereof, thanks to that the moveable clamp member (4) has a thread-type structure that screws on the cylinder (12) that acts like a nut, although it could also be done reversely.
  • This moveable screwed clamp member (4) carries out the same task as the conventional adjusting screw of this type of pressure tool.
