20110123291 | ANCHOR BOLT ASSEMBLY - An anchor bolt assembly includes a sleeve affixed to a first plate member and having a locating groove extending around the inside wall thereof, a retaining member having a shank and a head provided with a retaining ring and movable in and out of the sleeve, a spring member adapted for forcing the retaining member out of the sleeve to a locking position to lock a second plate member to the first plate member and a pull cap connected to the distal end of the shank for pulling by the user to move the retaining member away from the locking position to an unlocking position where the second plate member is unlocked from the first plate member and the retaining ring is engaged with the locating groove to hold the retaining member in the unlocking position. | 05-26-2011 |
20110135421 | METAL PLATE MEMBER FIXATION DEVICE - A metal plate member fixation device includes an adapter having a hollow base and a tubular bonding portion perpendicularly extended from the hollow base for bonding to a mounting through hole of a first metal plate member, and a locking device formed of a barrel, which is detachably connectable to the hollow base of the adapter before bonding of the adapter to the first metal plate member, a driving member, a lock screw and a spring member and adapted for detachably locking the first metal plate member to a second metal plate member. | 06-09-2011 |
20110302759 | FLOATING CAPTIVE SCREW INSTALLATION METHOD - A floating captive screw installation method includes the step of inserting a lock screw through a spring member and then inserting the lock screw with the spring member into a stepped barrel, the step of inserting the stepped barrel with the spring member and the lock screw into a rotary cap to keep the head of the lock screw outside the rotary cap, the step of forcing a toothed engagement portion of the head of the lock screw into engagement with a retaining groove in the top open side of the rotary cap tightly, and the step of letting a front coupling flange of the rotary cap be stopped against the bottom side of a top coupling flange of the stepped barrel. This installation method eliminates a secondary processing process, saving much installation labor and time. | 12-15-2011 |
20120040035 | CAPTIVE SCREW FABRICATION MOLD - A captive screw fabrication mold for molding a plastic or rubber knob on the head of a lock screw for captive screw is disclosed to include a bottom die having a tubular post vertically disposed in each bottom die cavity thereof for holding a lock screw for molding, and an upper die that has an annular rib vertically downwardly suspending in each upper die cavity thereof for stopping against the head of the lock screw in the associating bottom die cavity around the top protrusion of the lock screw to isolate the molding chamber in each upper die cavity, avoiding overflow of the applied molten material into the tool groove in the top protrusion of each lock screw. | 02-16-2012 |
20120099943 | Captive fastener - A captive fastener includes a mounting base member bonded to a first panel frame, a locking shank loaded with a spring member and axially movably mounted in the mounting base member hole for engaging into a mounting through hole of a second panel frame to detachably lock the second panel frame to the first panel frame, and a driving member, which is coated with a color index coating for identification and connected to the locking shank after bonding the mounting base member to the first panel frame and operable to move the locking shank between a locking position where the first panel frame and the second panel frame are locked and an unlocking position where the first panel frame is detachable from the second panel frame. | 04-26-2012 |
20120170993 | QUICK-POSITIONING CAPTIVE SCREW - A quick-positioning captive screw includes a mounting base member having an outer thread spirally extending around the peripheral wall of a top flange thereof, the outer thread having a leading end terminating in the top edge of the top flange and a tail end terminating in the bottom edge of the top flange and cutting a part of the top flange into a rib, a lock screw having an inner thread located on the inside wall of a plastic cap thereof for threading through the outer thread into the space around the periphery of the mounting base member below the bottom edge of the top flange after bonding of the mounting base member to an external panel frame by reflow soldering, and a spring member sleeved onto the threaded shank of the screw bolt of the lock screw and stopped between the head of the screw bolt and the inside step of the mounting base member. | 07-05-2012 |
20120189401 | FASTENING STRUCTURE - A fastening structure includes a thin, light weight, low torque metal plate member having a mounting through hole, and a fastening member, which has a shank body, a mounting flange extending around the periphery of the bottom end of the shank body and riveted to the mounting through hole and a screw hole on the shank body for the fastening of an external screw member to secure an external circuit board to the top end of the shank body at a distance from the plate member. The mounting flange has a tapered peripheral wall reducing gradually upwardly from the bottom end of the shank body toward the top end thereof and riveted to a mounting through hole of the plate member and a step located on the topmost edge of the tapered peripheral wall around the periphery of the shank body and kept in flush with the top wall of the plate member. | 07-26-2012 |
20140173877 | HOLELESS PLATE MEMBER RIVETING METHOD - A holeless plate member riveting method for riveting a retaining member to a holeless plate member using a press by: placing the holeless plate member on a first die of the press and attaching a mounting structure of the retaining member to the holeless plate member opposite to the first die, and then attaching a cavity of a second die of the press to the retaining member, and then operating the press to stamp the second die against the retaining member and the first die, forcing a cutting edge of the mounting structure of the retaining member to cut into the holeless plate member to the extent where a toothed portion and annular locating groove of an engagement structure of the retaining member are kept in permanent engagement with a deformed part of the holeless plate member. | 06-26-2014 |
