  "abstract": "Provided is a wire grip, which has excellent workability for bracing the wire and which can grip a linear object for bracing the wire without applying any excessive load to the linear object. The wire grip comprises a stationary-side wire gripping portion having a body and a movable-side wire gripping portion, whereby a linear object can be gripped between them, where a first action portion for moving the movable-side wire gripping portion back and forth and a second action portion connected to the first action portion by a connecting rod are turnably attached to the body, whereby the connecting rod is pulled substantially parallel to the gripping portions so that the connecting rod, and the first and second action portions are linked to act to move the movable-side wire gripping portion towards the stationary-side wire gripping portion.",
  "claims": [
    "1. A wire grip, comprising; a body (10); a stationary-side wire gripping portion (1) provided in said body (10); a movable-side wire gripping portion (2) being movably provided to face said stationary-side wire gripping portion (1); a first action portion (3) being provided on said body (10) at a first pivot (31); wherein said first action portion (3) has a substantial L-shape including two arms, said first pivot (31) being located between said two arms; wherein said first action portion (3) is further turnably connected with said movable-side wire gripping portion (2) at a working point (33) located at one of said two arms; a connecting rod (5); wherein a first end of said connecting rod (5) is turnably connected with the one of said two arms at a second pivot point (32); a second action portion (4) being pivotably located on said body (10) at a third pivot (41); wherein an intermediate portion of said connecting rod (5) is turnably connected with said second action portion (4) at a fourth pivot (42); whereby an electric wire (W) gripped between said movable-side wire gripping portion (2) and said stationary-side gripping portion (1) when a second end of said connecting rod (5) is pulled substantially parallel to said movable-side wire gripping portion (2) and said stationary-side wire gripping portion (1).",
    "2. The wire grip of claim 1, wherein the second end of said connecting rod (5) is located in the vicinity of a line extending proximally from said movable-side wire gripping portion (2).",
    "3. A method of gripping a wire using a wire grip according to claim 1, comprising the steps of: i. arranging an electric wire (W) between said movable-side wire gripping portion (2) and said stationary-side wire gripping portion (1); ii. pulling the second end of said connecting rod (5) in a direction substantially parallel to said movable-side wire gripping portion (2) and said stationary-side wire gripping portion (1) so that the electric wire (W) is gripped between said movable-side wire gripping portion (2) and said stationary-side wire gripping portion (1)."

  "description_excerpt": "The present invention relates to a wire grip used for gripping a linear object such as an electric wire, i.e. an electric power wire and a communication wire and an elevator wire to brace the linear object.\n\nConventionally, for bracing the wire in an electric wire construction, a wire grip that grips the electric wire is used to pull the electric wire by a wire puller. However, most of the conventional wire grips have problems of working inefficiency. For example a worker must move during a step of inserting a linear object (an electric wire) and a step of fixing the linear object by a grip member of the wire grip. Therefore, the wire grips have been required to improve their efficiency when they are used to brace wires in a dangerous situation such as work in high places and in a small area where work space is limited. Therefore, the wire grip 500 described as follows has been suggested and introduced (see The Patent Document 1). The wire grip 500 has a structure in which a action portion 503 activates a movable-side wire gripping portion 52 to grip the linear object W when a stationary-side wire gripping portion 501 as described in FIG. 5 is hung on the linear object and then a an arc-like pulling portion 504 inserted into an inserting opening 505 is pulled in the direction of an arrow A. And the wire grip 500 can also be operated easily by workers without moving from a front side of the wire grip 500.\n\nHowever, in the wire grip 500 shown in FIG. 5, since the pulling portion 504 is pulled in the direction of the arrow A (obliquely downward to the right as shown in FIG.",
