A latch assembly is provided that includes a latch arm having a rotational axis and an engagement surface on a distal end of the latch arm a length from the rotational axis. The engagement surface is stowed in a stowed state of the latch arm. The latch arm is configured to receive a pushing force to depress the latch arm a predetermined distance along the rotational axis. The latch assembly also includes a turret assembly having a top end with the latch arm mounted thereon. The turret assembly is configured to, in response to the pushing force being applied to the latch arm, raise and rotate the latch arm about the rotational axis to thereby transition the latch arm from the stowed state to a deployed state in which the engagement surface is exposed.

A latch is configured to fix a panel relative to a frame. The latch includes a housing having a longitudinal axis and defining an aperture along the longitudinal axis; a cap mounted within the aperture of the housing for rotation about the longitudinal axis, the cap comprising a drive surface; and a cover coupled to the housing to pivot about a lateral axis, the cover pivotable to be in a closed position in which the cover covers the cap; wherein when the cap is in an unlatched position, the drive surface of the cap is aligned with an engagement surface of the cover and positioned to block the cover from pivoting to the closed position; and wherein when the cap is in a latched position, the drive surface is unaligned with the engagement surface and positioned to permit the cover to pivot to the closed position.

A multi-axial catch comprises a mount and a catch body coupled to the mount. The mount affixes the catch to a frame and the catch body has a recess to position a latch head of a latch within the recess to engage the latch with the catch. The catch can include a cam to form the recess. The catch rotates around a rotation axis in response to a longitudinal motion of the latch. The catch body is coupled to the mount to allow the catch body to rotate around a pivot axis in response to a transverse motion of the latch. The catch includes an elastic coupler to position the catch in a rotational at-rest position and an elastic coupler to position the catch-body in a transverse at-rest position. The recess allows the latch head to move laterally, in response to a lateral motion of the latch, within the catch.

A lockable manhole cover incudes, for example, a manhole cover installable in an opening in a manhole frame, a locking member attached via a pin and slot arrangement beneath the manhole cover, and a lever pivotally attached to the manhole cover. A lower end portion of the lever is operably engageable with the locking member to move the locking member relative to the manhole cover. The lever is disposable in a lowered position so that an end portion of the locking member is operably engageable with a portion of the manhole frame for use in inhibiting removal of the lockable manhole cover from the manhole frame. The lever is disposable in a raised position so that the end portion of the locking member is operably disengageable with the portion of the manhole frame to allow removal or installation of the lockable manhole cover from or in the manhole frame.

An openable roof lock structure for an automobile includes an engaged member fixed to a front header, and an automatic lock device fixed to an openable roof, the automatic lock device being attachable to and detachable from the engaged member. The automatic lock device includes a hook member having a leading end portion in one end, the leading end portion to be engaged with the engaged member, and a drive part to which the other end of the hook member is coupled, the drive part turning the hook member to an upper side of a vehicle to engage the hook member with the engaged member. The hook member includes a buffering member that has elasticity and is abutted with the engaged member on the upper side of the vehicle in a state that the leading end portion is not engaged with the engaged member.

A portable securing apparatus which is readily secured to a manway of a vessel having a portal intended to enable entry of service personnel into the vessel is described. The securing apparatus affords an improved grip to assist service personnel to enter the vessel. The securing apparatus is for temporary mounting to the manway. The securing apparatus includes a mounting plate mountable to a flange conventionally provided as part of the manway, and a handle for accommodating manual grasp of the securing apparatus.

A back-and-forth movement device includes a guiding section that regulates an operation between a case-side member and a forward/backward member, and a guided section to be guided by the guiding section. In the back-and-forth movement device, a case partly includes a proximate wall portion that is in proximity to the forward/backward member, the guiding section is provided on a side opposite to the forward/backward member with respect to the proximate wall portion, and an engaging section of a restriction member and an extending portion of the guided section extend substantially parallel to each other on the side opposite to the forward/backward member with respect to the proximate wall portion.
