MANUAL GRIPPING DEVICE FOR CLAMPING OBJECTS

摘要

The invention relates to a mechanical device for manually clamping objects (10), which allows a user to clamp objects which, owing to their characteristics, uses or processes, would be dangerous to the users hand, as well as simply to clamp different objects. The device consists of five main parts: an upper jaw (15), a lower jaw (25), an upper handle (45), a lower handle (30), and a simple lever two-point shaft (65). In order to clamp an object with the device, the user inserts his/her thumb into the buttonhole for the thumb (35) in the lower handle (30) and the rest of the fingers into the upper handle (45) in the space between the handle (50) and the finger-adjustment rod assembly (60). By expanding the fingers of the hand the upper (15) and lower (25) jaws open and by contracting the fingers the jaws close. Objects are clamped in an extension of the forearm, on the side opposite the palm of the hand. This device (10) can be used ambidextrously by making a simple change to the assembly of the lower handle (30).

1) A mechanical device for manually clamping objects, designed to be a device for clamping objects which, owing to their characteristics, uses or processes, would be dangerous to the user's hands, as well as simply to clamp different objects, consists of an upper jaw, a lower jaw, a simple lever two-point shaft, an upper handle, and a lower handle, characterized by, to the use of this device by the user, the simple lever two-point shaft is located in parallel way to the axis formed by the fingers of the hand when these form a fist, and is located on the side opposite the palm of the hand, wherein to exert pressure by the hand of user on the upper handle and the lower handle, it generates torques that are transferred by the simple lever two-point shaft, causing the opening or closing of the upper jaw and the lower jaw, wherein the clamping objects are made in an extension of the forearm, on the side opposite the palm of the hand, wherein this device is for ambidextrous use by making a simple change in the assembly of the lower handle, this device comprise:
a) a laminar structure which imitates the shape of the upper jaw of the bony structure of a mammal, called upper jaw, with an array of teeth for clamping abrasion, with two holes in its middle part for the assembly with the lower jaw and with the simple lever two-point shaft, and with two holes in its lower part for the assembly with the upper handle, b) a laminar structure which imitates the shape of the lower jaw of the bony structure of a mammal, called lower jaw, with an array of teeth for clamping abrasion, with two holes in its middle part for the assembly with the upper jaw and with the simple lever two-point shaft, and with two holes in its lower part for the assembly with the lower handle, c) an axis of simple lever, called simple lever two-point shaft, which is used for the transference of the torques generated by the pressure of the user's hand on the upper handle and the lower handle, which for principle of simple lever generate torques on the upper jaw and the lower jaw, d) an upper handle assembly, called upper handle, which is used by the user to generate a torque by the pressure of the hand of the user on this handle, torque which is transferred by the simple lever two-point shaft to the upper jaw, e) a lower handle assembly, called lower handle, which is used by the user to generate a torque by the pressure of the hand of the user on this handle, torque which is transferred by the simple lever two-point shaft to the lower jaw, Wherein, before of a clamping object operation, the thumb of the hand is inserted in the buttonhole for the thumb of the lower handle, and the others fingers of the hand (from the index finger to the little finger) are inserted in the upper handle, in the space between the handle and the finger-adjustment rod assembly. Where a clamping object operation is realized by the following steps: (1) Opening operation—to the expansion of the fingers of the user's hand, makes the upper handle and the lower handle separate between them, in order to open the upper jaw and the lower jaw. (2) Closing operation—to the contraction of the fingers of the user's hand, makes exert pressure on the handles of the upper handle and the lower handle, in order to close the upper jaw and the lower jaw.
