Abstract
A device for hanging a building member contains a gripper adapted to be secured to an anchor member embeded in a ceiling wall of a building, a wire article hanging from and secured to the gripper at its one end, and a second gripper adapted for securing the other end of the wire article and for hanging a building member. The gripper allows the wire article to pass in one direction along the longitudinal direction of the wire article but not in the opposite direction.

A device for hanging a building member comprising wire article securing means adapted to be secured to an anchor member secured to a ceiling wall of a building for hanging and securing a wire article, and building member securing means adapted to be hung and secured by said wire article for hanging a building member, at least one of said wire article securing means and said building member securing means comprising a kit consisting of a wire article gripper and a wire article extraction device, said wire article gripper including an outer casing having an inner surface tapering towards one end of the casing and having an opening for introducing a wire article therethrough, a split gripping element accommodated within said outer casing and having a tapered outer surface complementary to said tapered inner surface, and a spring member held between a spring holding element secured within said outer casing and said split gripping element, said spring member normally biasing said split gripping element towards said one end, the arrangement being such that, when the wire article is forced to be inserted through said opening into said outer casing against the action of said spring member, said gripping element is moved along said tapered surfaces while being extended radially outward to permit said wire article to be introduced into the inside of said outer casing and after the wire article is introduced to a predetermined position and when the forcing operation is discontinued, the spring member thrusts the split gripping element along the tapered surfaces until the wire article is clamped and secured in position by the gripping element, said wire article extraction device including a disk having a radial slot for introducing the wire article thereinto from the outside and a central opening communicating with said radial slot and a semicylindrical shank having an inside diameter equal to the diameter of said central opening, said wire article extraction device being applied from outside to the portion of the wire article extending above said wire article gripper when said wire article is inserted into and clamped in said wire article gripper, said portion of said wire article being then received in said central opening and in said shank, and said wire article extraction device being then lowered through said opening onto the upper surface of said split gripping element to cause said split gripping element to be lowered and simultaneously extended apart radially against the force of said spring to release said wire article.
A device for hanging a building member comprising wire article securing means adapted to be secured to an anchor member secured to a ceiling wall of a building for hanging and securing a wire article, and building member securing means adapted to be hung and secured by said wire article for hanging a building member, at least one of said wire article securing means and said building member securing means comprising a kit consisting of a wire article gripper and a wire article extraction tool, said wire article gripper including an outer casing having an inner surface tapering towards one end of the casing and having an opening for introducing a wire article therethrough, a split gripping element accommodated within said outer casing and having a tapered outer surface complementary to said tapered inner surface, a cylindrical holder within said outer casing, and a spring member held between a spring holding element secured within said outer casing and said holder, said spring member normally biasing said split gripping element towards said one end, the arrangement being such that, when the wire article is forced to be inserted through said opening into said outer casing against the action of said spring member, said gripping element is moved along said tapered surfaces while being extended radially outward to permit said wire article to be introduced into the inside of said outer casing and after the wire article is introduced to a predetermined position and when the forcing operation is discontinued, the spring member thrusts the split gripping element along the tapered surfaces until the wire article is clamped and secured in position by the gripping element, a through-hole being formed in said holder for introducing said tool therethrough into the inside of said outer casing to move said holder and said spring member such that said gripping element is moved along said tapered surfaces and simultaneously extended radially outward to release said wire article.
A device for hanging a building member comprising wire article securing means adapted to be secured to an anchor member secured to a ceiling wall of a building for hanging and securing a wire article, and building member securing means adapted to be hung and secured by said wire article for hanging a building member, at least one of said wire article securing means and said building member securing means comprising a kit consisting of a wire article gripper and a wire article extraction tool, said wire article gripper including an outer casing having an inner surface tapering towards one end of the casing and having an opening for introducing a wire article therethrough, a split gripping element accommodated within said outer casing and having a tapered outer surface complementary to said tapered inner surface, and a spring member held between a spring holding element secured within said outer casing and said split gripping element, said spring member normally biasing said split gripping element towards said one end, the arrangement being such that, when the wire article is forced to be inserted through said opening into said outer casing against the action of said spring member, said gripping element is moved along said tapered surfaces while being extended radially outward to permit said wire article to be introduced into the inside of said outer casing and after the wire article is introduced to a predetermined position and when the forcing operation is discontinued, the spring member thrusts the split gripping element along the tapered surfaces until the wire article is clamped and secured in position by the gripping element, a through-hole being formed in said outer casing for introducing a tool therethrough into the inside of said outer casing to move said spring member such that said gripping element is moved along said tapered surfaces and simultaneously extended radially outward to permit said wire article to be passed freely through the gripper to release the wire article.
