Magnetic latch for fastening a hinged closure member to a support
A magnetic latch for fastening a closure member to a support. The magnetic latch comprises a keeper assembly including a magnet and a latch bolt assembly having: an elongated frame (32); a latch bolt (14) moveable between a latching position and a retracted position; a latch bolt biasing member urging the latch bolt into its retracted position; and a latch bolt operating mechanism configured to move the latch bolt from its latching position to its retracted position against a magnetic attraction. The latch bolt operating mechanism comprises: an effort link rod (37); a load link rod (34); and a second-order lever (35) interposed between the effort link rod and the load link rod. The second-order lever reduces the force required to operate the latch bolt operating mechanism thus allowing for an increased magnetic attraction of the latch bolt towards the magnet in the keeper assembly.

HLOCK Temporary Construction Door Latch
A Temporary Construction door latch/lock is disclosed which is both rugged and economical. The latch includes a half circle flanged housing which acts as a bushing for a journal portion of an operator. The operator includes 2 slots (For 2″¾ and 2″⅜ size doors) to accommodate the latching and the locking pin that serves also as the handle portion to move the latch back to open the door. At the inner end of the operator, a generally cylindrical latch is placed to the interior of the housing through the face of the door to interact with the frame. The latch moves back and force with respect to the housing and is limited in movement by a spring goes inside the housing. The latch is secured to the operator by a latching and a locking pin, which means to prevent the whole latch to come apart. The housing is fixed to the door by securement means which draws the flange of the housing against the exterior of the door.
Fenestration cam lock assemblies and methods
Fenestration lock assemblies, fenestration units including the lock assemblies, and methods of assembling the lock assemblies. The lock assemblies use a cam and follower design that transfers rotary motion to a lock bolt that moves in translation between an extended/locked state and a retracted/unlocked state.

Gate apparatus with springless automatic return gate
A gate apparatus having an automatically returning gate, an upper latch operated by an upper button, and a lower latch operated by an upper finger handle. Each of the latches must be opened to open the gate. The gate returns without the aid of a spring to a position close to the closed position or to the closed position by the structure of a pivot or hinge connection between the gate and the frame of the gate. Gate tubes are rectangular in section for their entire length. Wood panels are included in the gate and excluded from other portions of the gate apparatus to make the gate stand out to the user seeking to open the gate.

Barrier with structurally different corner gate connections
A barrier that includes four structurally different corner connections for fixing a gate frame of the barrier to and between opposing vertical surfaces. A first connection includes a headed straight pin engaging a pivot hook and socket, a second connection includes a headed straight pin engaging a socket, a third connection includes headless bent pin engaging a socket and a limiter, and a fourth connection includes a headless bent pin engaging a socket.
Latch mechanism of storage case
A latch mechanism of a storage case where a case cover is openably and closably connected to a case body, the latch mechanism includes a latch arm connected to the case body and an arm receiving portion provided on the case cover. A hook is formed on a tip side of the latch arm. A locking claw is formed on a tip side of the arm receiving portion. The arm receiving portion is formed with an inclined surface that guides the hook toward a claw tip of the locking claw.
