Abstract
A pair of projection elements 42, 42 are formed on the opposite sides of an inner link 4. Each projection element 42 is formed with a cutout recess 42b. A fitting shaft part 72a, which is formed on each end of an abutment shaft 72, is inserted into the cutout recess 42b through an open part thereof and turnably fitted to a bottom part of the cutout recess 42b. A second abutment part 71c of a coiled spring 71 is abutted with an enlarged-diameter part 72b of the abutment shaft 72. The abutment shaft 72 is biased towards the bottom side of the cutout recess 43b from the open part side thereof by the coiled spring 71.
Claims5
A hinge with catch comprising a skeleton side attaching member which can be attached to a skeleton;
- a door side attaching member which can be attached to a door;
- an inner and an outer link whose opposite ends are turnably connected to said skeleton side attaching member and said door side attaching member, respectively, so that said door side attaching member is turnably connected to said skeleton side attaching member between a closed position and an open position;
- an abutment member disposed generally in parallel relation to rotation axes of said inner and outer links and whose opposite ends are turnably supported by selected one of said inner and outer links;
- and biasing means for turnably biasing said door side attaching member through said abutment member and said selected link, by one end of said biasing means which is in abutment with said skeleton side attaching member and the other end thereof which is in abutment with an outer peripheral surface of said abutment member;
- wherein said selected link is provided with a pair of cutout grooves which are spacedly disposed in an axial direction of said abutment member, said pair of cutout grooves being formed such that opposite ends of said abutment member can be turnably inserted into said cutout grooves through open parts thereof until they reach bottom parts of said cutout grooves, said abutment member being pressed against the bottom parts of said cutout grooves by biasing force of said biasing means.
