A magnetic latch for a display of a laptop computer is disclosed. The latch uses magnetic attraction to maintain the display closed and uses magnetic repelling forces to pop-up the display when opened. The latch includes one or more magnetic elements in the body of the laptop and at least one magnetic element in the display. When the display is closed, the magnet element in the display is positioned adjacent the magnet element in the body having an opposite polarity so that the magnet elements are attracted to one another. To pop-up the display, the user moves the magnetic element in the display so that it meets the magnetic pole in the body having the same polarity. When these meet, the repelling force between them causes the display to open slightly so that a user can then readily open the display.

A hatch assembly for a marine vessel included a slam latch and a frame and a cover having the slam latch disposed therein. The slam latch includes a housing having inner and outer portions and a pivotal handle for rotation between open and closed positions. A reciprocal fastening element including a second cam surface is adapted to engage the frame for retaining the cover against the frame. A spring biases the handle into a closed position and together with the first cam surface maintains the handle in an opened position when the handle is rotated through a predetermined angle. The latch also includes a push rod for converting the rotation of the handle to the reciprocal movement of the fastening element. The latch also includes a pair of seals to prevent water from passing through the latch.

An oven latch includes a base, a pivot, and a latch arm with a slot that engages the pivot and allows the latch arm to slide and rotate relative to the pivot. A motor mounted on the base rotates a cam, and a rod connected between the cam and the latch arm closes the latch when the cam turns, thereby pivoting the latch arm closed to engage the oven door and sliding the latch arm inwards along the latch arm slot to pull in the door. The pivoting and sliding motion of the latch arm is controlled by a guide slot formed in the base having a normal guide portion and a repair guide portion. During normal operation, an end of the rod moves along the normal guide portion of the guide slot. If the motor fails, the end of the rod may be manipulated into the repair guide portion of the guide slot to open the latch when the motor and cam are in the closed position.

A safety gate for a doorframe, which is able to prevent small children from going into a restricted or dangerous area, has a lock that requires two different and independent steps to proceed the unlock process. Furthermore, after the lock is unlocked, the user still needs to lift the plate body before the pivotal movement of the plate body with respect to the first side bar is possible.

A crib railing includes a driving means, an opening/closing means and a railing coupling with the driving means and the opening/closing means. The driving means' seat has a top surface formed as a helical parabolic surface to allow the railing to automatically return at any angles relative to the driving means. The opening/closing means has an upper cover, a depressing means, a handgrip means, a slider, a lower cover and a linkage bar. The depressing means and handgrip means are single-handed operable at meantime, and can drive the linkage bar running through the handgrip means up and down to form an open or latch relationship with the railing. The handgrip means has a wedge with an inclined member to drive the slider to latch on a latch member of the railing. The invention provides the opening/closing movements of the driving means and opening/closing means and swiveling return of the railing.

A lock unit for a vehicle includes a rotatable catch biased in an opening direction about a catch rotation axis toward an open position of the lock unit in which a first recess of the catch is configured to receive a striker of the vehicle. Additionally, the catch includes a second recess disposed before the first recess in the opening direction. A pawl including a slot rotatable about a fixed pawl pivot axis is biased toward both the catch and the pawl pivot axis. The pawl includes a blocking arm which extends into the second recess of the catch when the lock unit is in a secondary latched position. A blocking lever of a ratchet abuts the blocking arm of the pawl against the catch in a primary latched position of the lock unit preventing rotation of the pawl away from the catch. When the lock unit is forced from the secondary latched position to the primary latched position, the pawl moves in a longitudinal direction of the slot avoiding the rotational blocking action of the ratchet.
