|20140115834||TIE CLAMP - A tie clamp includes: a clamp body formed by bending an elastic metal material having a relatively long length as compared to the width thereof in a circular shape; a male restrainer and a female restrainer formed at the opposite end sides of the clamp body to restrain an object to be restrained; and an ear formed on each of the male restrainer and the female restrainer so that a tool can be used to reduce the diameter of the clamp body to turn the clamp body into a restraint state.||05-01-2014|
|20130280004||TORQUE CONTROL BOLT FOR HOSE CLAMP - Disclosed is a torque control bolt for a hose clamp, which is configured to transmit a torque from a tool to a fastening bolt of a hose clamp to induce the fastening of the hose clamp, and then to be ruptured to prevent the transmission of torque exceeding a set value so as to prevent the damage of the hose clamp and the hose. The control bolt includes: a rupture bolt with a fastening body to transmit the torque from the tool to a head of the fastening bolt; a coupling unit formed on the head and the rupture bolt and configured to keep the coupling force between the head and the rupture bolt; and a rupture section formed on the rupture bolt and configured to prevent the torque from the tool from being transmitted to the fastening bolt when the torque exceeds the set value.||10-24-2013|
|20130088006||TORQUE CONTROL CAP FOR HOSE CLAMP - Torque control cap for a hose clamp makes the hose clamp to fasten a hose with a set torque even if an excessive power if transferred to a fastening bolt. The cap is applied to the hose clamp comprising a clamp body formed by circularly bending a narrow and long plate member and a detachable means configured to fasten or release a hose through decreasing or increasing a diameter of the clamp body and installed at one of a right or left side end of the clamp body, and is configured to fasten a fastening bolt with an optimum torque in accordance with the selected hose and prevent the hose and the hose clamp from being damaged, and the torque control cap includes a fastening tip coupled to a head of the fastening bolt to transfer a fastening force of a tool to the fastening bolt, and a cutaway part.||04-11-2013|
|20130000083||HOSE CLAMP - A hose clamp includes: a clamp body having a plurality of screw holes passing therethrough; a coupling housing disposed at one side of the clamp body and into which an opposite side of the clamp body is inserted; and a coupling screw rotatably disposed in the coupling housing and engaged with the screw holes of the clamp body inserted within the coupling housing, wherein the clamp body includes a compensating means including at least one compensation bead formed at one side of the clamp body for resiliently fastening a hose by a degree by which a diameter of the hose is decreased so as to firmly tighten the hose. The hose clamp can prevent the compensation means from being deformed over the resilient area, so that the compensation means is not deformed over the resilient area.||01-03-2013|
